技术领域technical field

本申请涉及电子产品技术领域，特别涉及一种同步装置、应用该同步装置的可折叠壳体组件及应用该可折叠壳体组件的可折叠电子设备。The present application relates to the technical field of electronic products, and in particular, to a synchronization device, a foldable casing assembly using the synchronization device, and a foldable electronic device using the foldable casing assembly.

背景技术Background technique

随着技术的发展，可折叠电子设备(例如可折叠手机、可折叠平板电脑等)已经越来越多的出现在人们的工作和生活之中。可折叠电子设备在使用过程中，其柔性屏会发生弯折。此时，为了保证柔性屏弯折区域受力均匀、避免柔性屏损坏，需要使柔性屏的两个非弯折区域的转动是同步的，即需要使可折叠电子设备中支撑两个非弯折区域的两个壳体的转动是同步的。因此，如何保障折叠电子设备中支撑两个非弯折区域的两个壳体能够同步转动，一直是研发人员研发方向。With the development of technology, foldable electronic devices (such as foldable mobile phones, foldable tablet computers, etc.) have increasingly appeared in people's work and life. When a foldable electronic device is in use, its flexible screen will bend. At this time, in order to ensure that the bending area of the flexible screen is evenly stressed and avoid damage to the flexible screen, it is necessary to synchronize the rotation of the two non-bending areas of the flexible screen, that is, the foldable electronic device needs to support the two non-bending areas. The rotation of the two shells of the zone is synchronized. Therefore, how to ensure that the two housings supporting the two non-bending regions in the folding electronic device can rotate synchronously has always been the research direction of the researchers.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

本申请提出一种同步装置100，其应用于可折叠电子设备。可以理解地，可折叠电子设备包括柔性屏和可折叠壳体组件1000。The present application proposes a synchronization device 100, which is applied to a foldable electronic device. It can be understood that the foldable electronic device includes a flexible screen and a foldable housing assembly 1000 .

如图1所示，可折叠壳体组件1000包括第一壳体200、第二壳体300以及弯折部(未图示)；第一壳体200与第二壳体300并排且间隔设置；弯折部设于第一壳体200与第二壳体300之间，并具有背对设置的第一侧边和第二侧边，第一侧边朝向第一壳体200并与第一壳体200连接，第二侧边朝向第二壳体300并与第二壳体300连接；第一壳体200设有第一安装面，第二壳体300设有第二安装面，第一安装面在第一壳体200折叠于第二壳体300时与第二安装面相对设置或背对设置；柔性屏设于第一安装面和第二安装面之上。As shown in FIG. 1 , the foldable casing assembly 1000 includes a first casing 200, a second casing 300 and a bending portion (not shown); the first casing 200 and the second casing 300 are arranged side by side and spaced apart; The bent portion is disposed between the first casing 200 and the second casing 300 and has a first side and a second side opposite to each other, and the first side faces the first casing 200 and is connected with the first casing. body 200 is connected, the second side is facing the second shell 300 and is connected with the second shell 300; the first shell 200 is provided with a first mounting surface, the second shell 300 is provided with a second mounting surface, the first mounting surface When the first housing 200 is folded on the second housing 300, the surface is arranged opposite or opposite to the second installation surface; the flexible screen is arranged on the first installation surface and the second installation surface.

具体地，第一壳体200和第二壳体300均为长方体形的板状结构，二者大小相当，且共平面设置。第一壳体200内可形成容纳腔，用于安装可折叠电子设备的电器元件。同理，第二壳体300内也可形成容纳腔，用于安装可折叠电子设备的电器元件。弯折部可由若干刚性单元通过排列和铰接而成(类似手表钢带的结构)。弯折部也为长方体形，其两条较长的侧边——第一侧边和第二侧边背对设置。弯折部设置于第一壳体200与第二壳体300之间，并与第一壳体200和第二壳体300共平面设置。弯折部的第一侧边朝向第一壳体200设置，并与第一壳体200的面向第二壳体300的侧边连接，弯折部的第二侧边朝向第二壳体300设置，并与第二壳体300的面向第一壳体200的侧边连接。此时，由于弯折部可进行弯折操作，第一壳体200相对于第二壳体300便可折叠，并具有折叠状态和展开状态。相对地，第二壳体300相对于第一壳体200也可折叠，并具有折叠状态和展开状态。需要说明的是，第一壳体200的展开状态是指第一壳体200相对于第二壳体300平铺时的状态；同样地，第二壳体300的展开状态是指第二壳体300相对于第一壳体200平铺时的状态。Specifically, the first casing 200 and the second casing 300 are both cuboid-shaped plate-like structures, and the two are of the same size, and are disposed coplanarly. A receiving cavity may be formed in the first housing 200 for installing electrical components of the foldable electronic device. Similarly, an accommodating cavity may also be formed in the second housing 300 for installing the electrical components of the foldable electronic device. The bent part can be formed by arranging and hinged several rigid units (similar to the structure of a watch steel band). The bent portion is also in the shape of a rectangular parallelepiped, and its two longer sides, the first side and the second side, are arranged opposite to each other. The bent portion is disposed between the first casing 200 and the second casing 300 and coplanar with the first casing 200 and the second casing 300 . The first side of the bending portion is disposed toward the first casing 200 and is connected to the side of the first casing 200 that faces the second casing 300 , and the second side of the bending portion is disposed toward the second casing 300 , and is connected with the side of the second casing 300 facing the first casing 200 . At this time, since the bending portion can perform a bending operation, the first casing 200 can be folded relative to the second casing 300, and has a folded state and an unfolded state. Conversely, the second casing 300 is also foldable relative to the first casing 200, and has a folded state and an unfolded state. It should be noted that the unfolded state of the first housing 200 refers to the state when the first housing 200 is tiled relative to the second housing 300 ; similarly, the unfolded state of the second housing 300 refers to the state of the second housing 300 The state when 300 is tiled relative to the first housing 200 .

这样，当可折叠电子设备的折叠是内折形式时，且在第一壳体200处于折叠状态时(即，在第一壳体200折叠于第二壳体300时；也即，在第二壳体300折叠于第一壳体200时；亦即，在第二壳体300处于折叠状态时)，第一壳体200的第一安装面与第二壳体300的第二安装面相对设置，即第一壳体200和第二壳体300叠合；而在第一壳体200处于展开状态时(即第二壳体300处于展开状态时)，第一壳体200的第一安装面与第二壳体300的第二安装面则共平面设置。类似地，当可折叠电子设备的折叠是外折形式时，且在第一壳体200处于折叠状态时(即，在第一壳体200折叠于第二壳体300时；也即，在第二壳体300折叠于第一壳体200时；亦即，在第二壳体300处于折叠状态时)，第一壳体200的第一安装面与第二壳体300的第二安装面背对设置，即第一壳体200和第二壳体300叠合。而在第一壳体200处于展开状态时(即第二壳体300处于展开状态时)，第一壳体200的第一安装面与第二壳体300的第二安装面则共平面设置。In this way, when the folding of the foldable electronic device is in the form of inward folding, and when the first case 200 is in a folded state (ie, when the first case 200 is folded to the second case 300; that is, when the second case 200 is folded When the housing 300 is folded to the first housing 200; that is, when the second housing 300 is in a folded state), the first mounting surface of the first housing 200 is disposed opposite to the second mounting surface of the second housing 300 , that is, the first housing 200 and the second housing 300 are superimposed; and when the first housing 200 is in the unfolded state (ie, when the second housing 300 is in the unfolded state), the first mounting surface of the first housing 200 The second mounting surface of the second casing 300 is coplanar. Similarly, when the folding of the foldable electronic device is in the form of outward folding, and when the first casing 200 is in a folded state (ie, when the first casing 200 is folded to the second casing 300; that is, when the first casing 200 is folded on the second casing 300; When the second casing 300 is folded to the first casing 200; that is, when the second casing 300 is in the folded state), the first mounting surface of the first casing 200 and the second mounting surface of the second casing 300 are behind The pair is arranged, that is, the first casing 200 and the second casing 300 are superimposed. When the first housing 200 is in the unfolded state (ie, when the second housing 300 is in the unfolded state), the first mounting surface of the first housing 200 and the second mounting surface of the second housing 300 are coplanar.

柔性屏贴装于第一壳体200的第一安装面和第二壳体300的第二安装面之上，以随第一壳体200相对于第二壳体300的开合运动(或随第二壳体300相对于第一壳体200的开合运动)，呈现不同的使用状态，从而满足用户不同的操作需求。此时，可以理解地，柔性屏被划分成为两个非弯折区域和一个弯折区域，一个非弯折区域由第一壳体200支撑，另一个非弯折区域由第二壳体300支撑，弯折区域则由弯折部支撑。The flexible screen is mounted on the first mounting surface of the first housing 200 and the second mounting surface of the second housing 300, so as to follow the opening and closing movement of the first housing 200 relative to the second housing 300 (or with the The opening and closing motion of the second casing 300 relative to the first casing 200 ) presents different use states, so as to meet the different operation requirements of the user. At this time, it can be understood that the flexible screen is divided into two non-bending areas and one bending area, one non-bending area is supported by the first casing 200 , and the other non-bending area is supported by the second casing 300 , the bending area is supported by the bending part.

基于前述可折叠电子设备的结构，为了使可折叠电子设备中支撑柔性屏的两个非弯折区域的两个壳体能够同步转动，从而使柔性屏的两个非弯折区域能够同步转动，保证柔性屏弯折区域受力均匀，避免柔性屏损坏；Based on the structure of the aforementioned foldable electronic device, in order to enable the two housings supporting the two non-bending areas of the flexible screen in the foldable electronic device to rotate synchronously, so that the two non-bending areas of the flexible screen can rotate synchronously, Ensure that the bending area of the flexible screen is evenly stressed and avoid damage to the flexible screen;

此时，结合图1，可以理解地，当第一连接臂20随可折叠电子设备的第一壳体200而转动时，由于第一滑动件40和第二滑动件50是同步且朝相反方向运动的，第一连接臂20便可通过与其传动连接的第一滑动件40、以及连接在第一滑动件40和第二滑动件50之间的连接组件60，驱动第二滑动件50发生与第一滑动件40同步的且朝相反方向的运动，从而通过第二滑动件50驱动与其传动连接的第二连接臂30发生与第一连接臂20同步的转动、且转动方向与第一连接臂20的转动方向相反，进而通过第二连接臂30驱动可折叠电子设备的第二壳体300发生与第一壳体200同步的转动，且转动方向与第一壳体200的转动方向相反，直至第一连接臂20和第二连接臂30叠合(即第一连接臂20和第二连接臂30均处于折叠状态)，直至第一壳体200和第二壳体300叠合(即第一壳体200和第二壳体300均处于折叠状态)。同理，当第二连接臂30随可折叠电子设备的第二壳体300而转动时，由于第一滑动件40和第二滑动件50是同步且朝相反方向运动的，第二连接臂30便可通过与其传动连接的第二滑动件50、以及连接在第一滑动件40和第二滑动件50之间的连接组件60，驱动第一滑动件40发生与第二滑动件50同步的且朝相反方向的运动，从而通过第一滑动件40驱动第一连接臂20发生与第二连接臂30同步的转动、且转动方向与第二连接臂30的转动方向相反，进而通过第一连接臂20驱动可折叠电子设备的第一壳体200发生与第二壳体300同步的转动，且转动方向与第二壳体300的转动方向相反，直至第一连接臂20和第二连接臂30叠合(即第一连接臂20和第二连接臂30均处于折叠状态)，直至第一壳体200和第二壳体300叠合(即第一壳体200和第二壳体300均处于折叠状态)。At this time, with reference to FIG. 1 , it can be understood that when the first connecting arm 20 rotates with the first housing 200 of the foldable electronic device, since the first sliding member 40 and the second sliding member 50 are synchronized and face opposite directions When moving, the first connecting arm 20 can drive the second sliding member 50 to interact with the first sliding member 40 through the first sliding member 40 drivingly connected thereto and the connecting assembly 60 connected between the first sliding member 40 and the second sliding member 50 . The first sliding member 40 moves synchronously and in the opposite direction, so that the second sliding member 50 drives the second connecting arm 30 connected to it to rotate synchronously with the first connecting arm 20, and the rotation direction is the same as that of the first connecting arm 20. 20 rotates in the opposite direction, and then drives the second casing 300 of the foldable electronic device to rotate synchronously with the first casing 200 through the second connecting arm 30, and the rotating direction is opposite to the rotating direction of the first casing 200 until The first connecting arm 20 and the second connecting arm 30 are overlapped (that is, both the first connecting arm 20 and the second connecting arm 30 are in the folded state), until the first housing 200 and the second housing 300 are overlapped (ie the first Both the case 200 and the second case 300 are in a folded state). Similarly, when the second connecting arm 30 rotates with the second casing 300 of the foldable electronic device, since the first sliding member 40 and the second sliding member 50 move synchronously and in opposite directions, the second connecting arm 30 The first sliding member 40 can be driven to synchronize with the second sliding member 50 through the second sliding member 50 that is drive-connected therewith and the connecting assembly 60 connected between the first sliding member 40 and the second sliding member 50. Movement in the opposite direction, so as to drive the first connecting arm 20 to rotate synchronously with the second connecting arm 30 through the first sliding member 40, and the rotation direction is opposite to the rotating direction of the second connecting arm 30, and then pass the first connecting arm 20 drives the first casing 200 of the foldable electronic device to rotate synchronously with the second casing 300, and the rotating direction is opposite to the rotating direction of the second casing 300, until the first connecting arm 20 and the second connecting arm 30 overlap. (that is, both the first connecting arm 20 and the second connecting arm 30 are in a folded state) until the first casing 200 and the second casing 300 are overlapped (that is, both the first casing 200 and the second casing 300 are in a folded state) state).

也即，通过本实施例的同步装置100，可有效控制第一连接臂20和第二连接臂30以相同的速度叠合或展开，使得第一连接臂20和第二连接臂30的运行速度得以同步，从而使可折叠电子设备中与两连接臂分别连接的两个壳体能够同步转动，进而使两个壳体支撑的柔性屏的两个非弯折区域能够同步转动，保证柔性屏弯折区域受力均匀，避免柔性屏损坏。That is, through the synchronization device 100 of this embodiment, the first connecting arm 20 and the second connecting arm 30 can be effectively controlled to overlap or unfold at the same speed, so that the running speed of the first connecting arm 20 and the second connecting arm 30 can be effectively controlled. can be synchronized, so that the two shells connected to the two connecting arms in the foldable electronic device can rotate synchronously, so that the two non-bending areas of the flexible screen supported by the two shells can rotate synchronously, ensuring that the flexible screen is bent. The folding area is evenly stressed to avoid damage to the flexible screen.

需要说明的是，本实施例的同步装置100，既可应用在外折形式的可折叠电子设备中，也可应用在内折形式的可折叠电子设备中。并且，同步装置100的第一滑动件40和第二滑动件50，既可在相互靠近的同步运动过程中，驱动第一连接臂20和第二连接臂30同步转动而叠合；也可在相互远离的同步运动过程中，驱动第一连接臂20和第二连接臂30同步转动而叠合。本领域技术人员可以根据实际产品需求进行合理设置，在此不再一一赘述。It should be noted that, the synchronization apparatus 100 in this embodiment can be applied to a foldable electronic device in an outwardly folded form, or in a foldable electronic device in an inwardly folded form.

Those skilled in the art can make reasonable settings according to actual product requirements, which will not be repeated here.

此外，可以理解地，当将同步装置100装配至可折叠电子设备的第一壳体200和第二壳体300之间时，可折叠电子设备的安装部上可配置出相应的避让空间，以容纳同步装置100。In addition, it can be understood that when the synchronization device 100 is assembled between the first housing 200 and the second housing 300 of the foldable electronic device, a corresponding avoidance space may be configured on the mounting portion of the foldable electronic device to avoid The synchronization device 100 is accommodated.

进一步地，为了增强第一滑块件滑动时的稳定性，以及增强第二滑动件50滑动时的稳定性，底座10沿第一连接臂20至第二连接臂30的方向开设有第一滑槽11，第一滑动件40至少部分插设于第一滑槽11内，第二滑动件50至少部分插设于第一滑槽11内。并且，由于第一滑块件和第二滑动件50均沿第一滑槽11进行滑动，底座10的垂直第一滑槽11长度方向的宽度得以减小，从而有利于减小底座10的体积，减少同步装置100的空间占比。Further, in order to enhance the stability of the first sliding member 50 when sliding, and to enhance the stability of the second sliding member 50 when sliding, the base 10 is provided with a first sliding member along the direction from the first connecting arm 20 to the second connecting arm 30 . In the groove 11 , the first sliding member 40 is at least partially inserted in the first sliding groove 11 , and the second sliding member 50 is at least partially inserted in the first sliding groove 11 . In addition, since the first sliding member and the second sliding member 50 both slide along the first chute 11 , the width of the base 10 in the vertical direction of the length of the first chute 11 is reduced, thereby helping to reduce the volume of the base 10 , reducing the space ratio of the synchronization device 100 .

此时，当第一连接臂20转动并驱动第一滑动件40朝背离第二滑动件50的方向滑动时，第一滑动件40通过第一连杆63可拉动第三滑动件61朝向第一滑槽11滑动；而当第三滑动件61朝向第一滑槽11滑动时，第三滑动件61通过第二连杆65便可推动第二滑动件50朝背离第一滑动件40的方向滑动，从而实现第一滑动件40和第二滑动件50朝相反方向同步滑动；此时，第一连接臂20和第二连接臂30同步转动而叠合。同理，当第一连接臂20转动并驱动第一滑动件40朝向第二滑动件50滑动时，第一滑动件40通过第一连杆63可推动第三滑动件61朝背离第一滑槽11的方向滑动；而当第三滑动件61朝背离第一滑槽11的方向滑动时，第三滑动件61通过第二连杆65便可拉动第二滑动件50朝向第一滑动件40滑动，从而实现第一滑动件40和第二滑动件50朝相反方向同步滑动；此时，第一连接臂20和第二连接臂30同步转动而展开。At this time, when the first connecting arm 20 rotates and drives the first sliding member 40 to slide in a direction away from the second sliding member 50 , the first sliding member 40 can pull the third sliding member 61 toward the first sliding member 61 through the first link 63 The sliding slot 11 slides; and when the third sliding member 61 slides toward the first sliding slot 11 , the third sliding member 61 can push the second sliding member 50 to slide away from the first sliding member 40 through the second link 65 , so that the first sliding member 40 and the second sliding member 50 slide in opposite directions synchronously; at this time, the first connecting arm 20 and the second connecting arm 30 rotate synchronously and overlap.

Similarly, when the second connecting arm 30 rotates and drives the second sliding member 50 to slide toward the first sliding member 40 , the second sliding member 50 can push the third sliding member 61 away from the first sliding slot through the second link 65 . 11; and when the third sliding member 61 slides in a direction away from the first sliding slot 11, the third sliding member 61 can pull the first sliding member 40 to slide toward the second sliding member 50 through the first link 63 , so that the first sliding member 40 and the second sliding member 50 slide in opposite directions synchronously; at this time, the first connecting arm 20 and the second connecting arm 30 rotate synchronously to expand.

可以理解地，该连接组件60，不仅可以保障第一滑动件40和第二滑动件50朝相反方向同步滑动，实现第一连接臂20和第二连接臂30同步转动；而且还具有运动空程少、同步性好、结构简单、制造方便、装配快捷、稳定性强、可靠性高等优点。Understandably, the connecting assembly 60 can not only ensure that the first sliding member 40 and the second sliding member 50 slide in opposite directions synchronously to realize the synchronous rotation of the first connecting arm 20 and the second connecting arm 30; It has the advantages of less quantity, good synchronization, simple structure, convenient manufacture, quick assembly, strong stability and high reliability.

进一步地，相较于相关技术中第一连接臂20与第二连接臂30之间通过多个齿轮副(例如6个齿轮所构成的5个齿轮副)来实现二者同步转动的方式，该连接组件60不论搭载前述齿轮齿条传动方式，还是搭载前述连杆机构传动方式，均可以有效减少第一连接臂20与第二连接臂30之间齿轮副的数量，减少同步装置100运行过程中运动空程的出现几率，从而提升同步装置100中第一连接臂20与第二连接臂30的同步性，实现可折叠电子设备中与两连接臂分别连接的两个壳体之间更好地同步转动，实现两个壳体支撑的柔性屏的两个非弯折区域之间更好地同步转动，进而提升柔性屏弯折区域受力的均匀性，降低柔性屏损坏的可能。Further, compared with the related art in which the first connecting arm 20 and the second connecting arm 30 are rotated synchronously through multiple gear pairs (for example, five gear pairs formed by 6 gears), the Regardless of whether the connecting assembly 60 is equipped with the aforementioned rack-and-pinion transmission method or the aforementioned link mechanism transmission method, the number of gear pairs between the first connecting arm 20 and the second connecting arm 30 can be effectively reduced, and the number of gear pairs during the operation of the synchronizing device 100 can be reduced. The occurrence probability of the motion idling is improved, thereby improving the synchronization between the first connecting arm 20 and the second connecting arm 30 in the synchronization device 100, and realizing a better connection between the two shells respectively connected to the two connecting arms in the foldable electronic device. Synchronous rotation achieves better synchronous rotation between the two non-bending regions of the flexible screen supported by the two housings, thereby improving the uniformity of force in the bending region of the flexible screen and reducing the possibility of damage to the flexible screen.

当然，在其他实施例中，也可以使用其他连接组件60来保障第一滑动件40和第二滑动件50朝相反方向同步滑动，例如：两根平行的滑动杆之间设置一个齿轮，滑动杆的面向齿轮的表面为齿条面，齿条面沿滑动杆的长度方向布局，并与齿轮的齿轮面啮合；齿轮转动，驱动两根滑动杆朝相反的方向滑动。至于更多其他方式，本领域技术人员可以根据连接组件60的功能作用合理实施，在此不再一一赘述。Of course, in other embodiments, other connecting components 60 can also be used to ensure that the first sliding member 40 and the second sliding member 50 slide synchronously in opposite directions, for example: a gear is arranged between two parallel sliding rods, and the sliding rods The surface of the gear facing the gear is a rack surface, and the rack surface is arranged along the length direction of the sliding rod and meshes with the gear surface of the gear; the rotation of the gear drives the two sliding rods to slide in opposite directions. As for other manners, those skilled in the art can reasonably implement them according to the functions of the connecting component 60 , which will not be repeated here.

进一步地，为了增强第三滑动件61滑动时的稳定性，增强连接组件60在与第一滑动件40和第二滑动件50配合时的稳定性，底座10沿第三滑动件61的滑动路径开设有第二滑槽13，第三滑动件61包括背对设置的滑动端和安装端，滑动端插设于第三滑槽内，第一连杆63的背对第一滑动件40的一端套设于安装端，第二连杆65的背对第二滑动件50的一端套设于安装端。Further, in order to enhance the stability of the third sliding member 61 when sliding, and enhance the stability of the connecting assembly 60 when it cooperates with the first sliding member 40 and the second sliding member 50 , the base 10 follows the sliding path of the third sliding member 61 . A second chute 13 is provided. The third sliding member 61 includes a sliding end and a mounting end that are opposite to each other. The sliding end is inserted into the third sliding groove. The end of the second link 65 facing away from the second sliding member 50 is sleeved on the installation end.

并且，为了防止第三滑动件61从第二滑槽13中脱出，使第三滑动件61滑动时的稳定性进一步增强，第二滑槽13具有两相对设置的侧壁，侧壁沿第二滑槽13的长度方向开设有限位凹槽131；滑动端的侧面朝向限位凹槽131凸设有限位块，限位块至少部分插设于限位凹槽131内。具体地，在图3所示的实施例中，背对设置的两限位块均沿滑动端的周向环绕设置并相互连接，并最终形成环状结构的限位块。此时，即便第三滑动件61发生了自转，第三滑动件61的限位块仍有部分插设于限位凹槽131内，保障了第三滑动件61自转状态下滑动时的稳定性。In addition, in order to prevent the third sliding member 61 from falling out of the second sliding slot 13 and further enhance the stability of the third sliding member 61 when sliding, the second sliding slot 13 has two opposite side walls, and the side walls are along the second A limiting groove 131 is defined in the longitudinal direction of the chute 13 ; a limiting block protrudes from the side of the sliding end toward the limiting groove 131 , and the limiting block is at least partially inserted into the limiting groove 131 . Specifically, in the embodiment shown in FIG. 3 , the two limiting blocks arranged opposite to each other are circumferentially arranged and connected to each other along the circumference of the sliding end, and finally form a limiting block of annular structure. At this time, even if the third sliding member 61 rotates, the limiting block of the third sliding member 61 is still partially inserted into the limiting groove 131, which ensures the stability of the third sliding member 61 when sliding under the autorotation state. .

进一步地，如图2和图3所示，第一连杆63包括相连接的第一杆段631和第二杆段633，第一杆段631的背对第二杆段633的一端套设于安装端，第二杆段633的背对第一杆段631的一端转动连接于第一滑动件40；第二连杆65包括相连接的第三杆段651和第四杆段653，第三杆段651的背对第四杆段653的一端套设于安装端，第四杆段653的背对第三杆段651的一端转动连接于第二滑动件50；第二杆段633相对于第一杆段631下沉设置，第三杆段651相对于第四杆段653下沉设置，第三杆段651位于第一杆段631与底座10之间。这样，有利于保障第三杆段651和第四杆段653处于同一高度位置，从而有利于提升连接组件60在与第一滑动件40和第二滑动件50配合时的稳定性，进而使得第一滑动件40与第二滑动件50的同步性得以提升。Further, as shown in FIGS. 2 and 3 , the first connecting rod 63 includes a first rod segment 631 and a second rod segment 633 that are connected to each other, and one end of the first rod segment 631 facing away from the second rod segment 633 is sleeved At the installation end, the end of the second rod section 633 facing away from the first rod section 631 is rotatably connected to the first sliding member 40; The end of the third rod section 651 facing away from the fourth rod section 653 is sleeved on the installation end, and the end of the fourth rod section 653 facing away from the third rod section 651 is rotatably connected to the second sliding member 50; the second rod section 633 is opposite to The first rod section 631 is set down, the third rod section 651 is set down relative to the fourth rod section 653 , and the third rod section 651 is located between the first rod section 631 and the base 10 . In this way, it is beneficial to ensure that the third rod section 651 and the fourth rod section 653 are at the same height position, which is beneficial to improve the stability of the connecting assembly 60 when it cooperates with the first sliding member 40 and the second sliding member 50, thereby making the first sliding member 40 and the second sliding member 50 stable. The synchronization between the first slider 40 and the second slider 50 is improved.
