It should be understood that the description is only illustrative and is not intended to limit the scope of the invention. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present invention.

The seat comprises a seat headrest 1 and a seat body 2, wherein the seat headrest 1 comprises a headrest main body 3, a headrest auxiliary piece 4, a containing space 5 and an actuator, the headrest main body 3 and the headrest auxiliary piece 4 are combined to form the containing space 5, the headrest main body 3 is positioned at the front part of the headrest, the headrest auxiliary piece 4 is positioned at the rear part of the headrest, and the containing space formed by combination is provided with an opening. The opening is positioned at the top or the side part of the headrest main body, and a storage cover (not shown) is arranged at the opening, and can cover the opening in a first mode and can be opened upwards or sideways in a second mode.

The seat headrest 1 further comprises a cover driver connected to the storage cover for driving the storage cover to move relative to the headrest body, wherein the storage cover is located at a closed position in a first mode, and the storage cover is located at an open position in a second mode. In fig. 1, the headrest body 3 is shown as the front half of the seat headrest 1, and the headrest auxiliary 4 is shown as the rear half of the seat headrest 1, both of which can be changed in position as required, i.e., the headrest auxiliary 4 is provided as the front half of the seat headrest 1, and the headrest body 3 is provided as the rear half of the seat headrest 1. As shown in fig. 2 and 3, the seat headrest 1 further comprises at least one telescopic mechanism 6 which is accommodated in the accommodation space 5 in the first mode and which protrudes from the accommodation space 5 in the second mode, and which is movable between the first and second modes by an actuator. An application load 7 is fixedly connected to the front end of the telescopic mechanism 6, and when the telescopic mechanism 6 extends out of the accommodating space 5, the application load 7 is located in front of the user of the headrest 1 by avoiding an obstacle (the head of the user sitting on the seat is shown as a circle in fig. 3).

The structure of the telescopic mechanism 6 will be described in detail. As shown in fig. 4-7, comprises a main arm 8 having an outer side and an inner side, an outer arm 9 having an outer arm end 13, an inner arm 10 having an inner arm end 14, the outer arm 9 being slidably connected to the main arm 8 on the outer side, the inner arm 10 being slidably connected to the main arm 8 on the inner side, a drive motor 11, a belt 12 provided in the main arm 8 and connected to the drive motor 11, the belt 12 being connected to the outer arm end 13 of the outer arm 9 and to the inner arm end 14 of the inner arm 10.

The main arm 8 includes a main body 15 and a cover 16, which are connected by a screw connection, a fitting connection, or other detachable connection, and have an accommodating space therein. The middle of the main body part 15 is provided with a driving belt movement limiting part 17, one end of the limiting part 17 is provided with a driving motor 11, other driving and rotating devices can be selected, the surface of the driving motor 11 can be provided with a toothed part which is matched with the inner surface of the driving belt 12, the other end of the limiting part 17 is provided with a driving belt sleeving part 18, and the driving belt sleeving part 18 can be selected as a gear or a common fixed end which synchronously rotates with the driving motor 11. In this way, the belt 12 is coupled to the drive motor 11 and the belt coupling portion 18, and the movement track of the belt 12 is restricted by the intermediate belt movement restricting portion 17 and the outer arm 9, the inner arm 10, and the main arm 8 together. When the drive motor 11 rotates, the toothed portions on the surface of the drive motor 11 and/or the toothed portions on the surface of the belt socket 18 (when a gear that rotates synchronously with the drive motor is selected) mesh with the toothed portions on the inner surface of the belt 12, driving the belt 12 to rotate, so that the outer arm 9 and the inner arm 10 move in opposite directions. The invention is driven by a single driving motor, thereby reducing the complexity of the extension device.

The length of the outer arm 9 is equal to that of the main arm 8, the outer arm end 13 is positioned at one end of the outer arm 9, and the outer arm 9 is fixedly connected to the transmission belt 12 through the outer arm end 13, so that the outer arm 9 moves along with the movement of the transmission belt 12, and the fixed connection can be in a clamping or sleeving or other fixed connection mode. Furthermore, the outer arm 9 is slidably connected to the main arm 8, said sliding connection being achieved by providing grooves and rails at the respective mating positions of the outer arm 9 and the main arm 8. The inner arm 10 is relatively short and is fixedly connected to the belt 12 via an inner arm end 14, so that the inner arm 10 moves along with the movement of the belt 12, and the fixed connection can be a clamping connection, a sleeving connection or other fixed connection mode. Furthermore, the inner arm 10 is slidably connected to the main arm 8, said sliding connection being achieved by providing grooves and rails at the corresponding mating positions of the inner arm 10 and the main arm 8.

The outer arm 9 slides along the outer side of the main arm 8, which has an outer start 19 and an outer end 20, the outer arm 9 moves between the outer start 19 and the outer end 20, the inner arm 10 slides along the inner side of the main arm 8, which has an inner start 21 and an inner end 22, and the inner arm 10 moves between the inner start 21 and the inner end 22. The outer starting end 19, the outer ending end 20, the inner starting end 21 and the inner ending end 22 are positioned at two ends of the main arm 8, and the outer starting end 19 and the inner starting end 21 are positioned at different sides, namely, at two ends of the main arm 8 respectively, and the outer ending end 20 and the inner ending end 22 are also positioned at two ends of the main arm 8. The telescopic mechanism 6 of the invention adopts the two-dimensional motion, thereby further reducing the complexity of the structure and facilitating the manufacture.

As shown in fig. 4, an end portion of the outer arm 9 extending outwards is provided with a load fixing portion 23, the load fixing portion 23 is used for fixing an application load 7 expected to be carried by the telescopic mechanism 6, the application load 7 shown in fig. 4 is an optical lens, and the application load 7 can be replaced according to different requirements of application occasions. The load securing portion 23 is shown only schematically in fig. 4, and its specific shape and configuration can be changed adaptively according to the application load 7 to be mounted. The other side of the inner arm 10, opposite the inner arm end 14, i.e. remote from the main arm 8, is provided with an application connection 24 to an application device (not shown) for fixedly connecting the telescopic mechanism 6 to the application device. The application connection 24 is schematically illustrated in fig. 4 as a gear, and other connection configurations that facilitate connection may be used. On the other hand, the load securing portion 23 may be provided on the side of the inner arm 10 toward the inner terminal end 22, and the application connecting portion 24 may be provided at a position of the outer arm 9 toward the outer terminal end 20 and away from the outer arm end 13.

The telescopic mechanism 6 further comprises a control switch electrically connected to the driving motor 11 for controlling the forward rotation and the reverse rotation of the driving motor 11, i.e. for controlling the extension and retraction movements of the telescopic mechanism 6. The control switch may be provided on the application device or in other convenient locations for operation. The control switch can also control the opening and closing of the storage cover 4 at the same time, so that when the storage cover 4 is opened, the telescopic mechanism 6 extends out of the storage space 5 from the front of the seat headrest 1.

As shown in fig. 5, the load fixing portion 23 may be rotated by a certain angle according to the operation of the control switch, so that the telescopic mechanism 6 is extended and retracted, so as to reduce the accommodation space 5.

The telescoping process of the telescoping mechanism 6 is described as having the components in a retracted state in the initial state of the telescoping mechanism 6, as shown in fig. 6. At this point the outer arm end 13 of the outer arm 9 is located at the outer start 19, said outer arm 9 substantially coinciding with the main arm 8, the inner arm end 14 of the inner arm 10 is located at the inner start 21, the whole telescopic mechanism 6 is in a retracted state with respect to the application device and is fixedly connected to the application device by means of the application connection 24. When the telescopic mechanism 6 needs to be used, a user presses a control switch button, the driving motor 11 starts to rotate, the driving belt 12 is driven to move by the motor, the inner arm 10 moves from the inner initial end 21 to the inner terminal end 22, the outer arm 9 moves from the outer initial end 19 to the outer terminal end 20, the main arm 8 extends outwards relative to the inner arm 10 in a direction away from the application device, and the outer arm 9 extends outwards relative to the main arm 8 in a direction away from the application device. When the fully extended state is reached, one end of the load securing portion 23 extends the length of the outer arm 9+ main arm 8 with respect to the application device, corresponding to the length of both main arms. When the control switch is pressed again (or the control switch has a different drive direction for the drive motor 11 controlled by a different button), the drive motor 11 is turned in the opposite direction, i.e. clockwise, and the main arm 8 and the outer arm 9 are moved relative to the inner arm 10 in a direction towards the application device until retracted or brought into close proximity to the application device.

Conductive members are provided on the outer and inner sides of the main arm 8, and conductive members are also provided on the inner and outer arms 10, 9 on the sides contacting the main arm 8, so that the inner and outer arms 10, 9 remain energized when they slide relatively on the main arm 8. The conductive member may be specifically configured to coat a conductive material on the contact side surfaces of the main arm 8, the outer arm 9 and the inner arm 10, or may be configured to coat a conductive material on the contact side surfaces of the main arm 8, and fix a conductive sheet or a conductive wire on the corresponding contact surfaces of the outer arm 9 and the inner arm 10, so that the inner arm 10 and the outer arm 9 remain energized when they slide relatively on the main arm 8. In this way, if the application load 7 mounted on the telescopic mechanism 6 is an electronic component or a current signal is required, the current signal can be transmitted to the mounted application load 7 through the inner arm 10, the main arm 8, and the outer arm 9. The current signal is provided by the application connection 24 being connected to a power source.

The application load 7 may be selected as an optical element, a communication device, a display, and/or a device with a photographing or video recording function, and the optical element may be a lens or glasses, including a reflecting mirror, a concave lens, a convex lens, a phenanthrene lens, or the like, or a lens with a magnifying effect, through which a user can see a virtual image. The communication equipment can be an earphone, a sound and/or a microphone, so that a user can conveniently use the communication equipment when communicating with the outside, and the device with a photographing or video recording function can be a camera or a mobile phone, so that the communication equipment is convenient for the user to use when needing to record images in front of the seat.

In addition, a sound system can be fixedly arranged in the storage space 5, so that a user can conveniently listen to music or other audio information in the riding process.

Another aspect of the invention provides a seat comprising a seat body 2 and a seat headrest 1 as described above, which seat can be fixedly mounted on a motor vehicle, but can of course also be used in the field of furniture or in other applications where it is desirable.
