In summary, it can be seen that, by controlling the movement of the sliding cover plate 140, the housing 200 and the sliding block 130 through the swing rod 120, the folding function of the folding device can be realized, and the folding device can be formed with a continuous and complete housing in any state, so that the integrity and the aesthetic property of the appearance of the device can be realized, and the continuous and complete housing can shield the internal structure of the folding device, thereby realizing the waterproof and dustproof performances of the device.

The hinge mechanism of the folding equipment provided by the embodiment of the application realizes the folding function of the equipment, the two shells and the screens of the folding equipment are respectively arranged at two sides of the hinge mechanism, the hinge mechanism comprises a main shaft assembly and two hinge assemblies, the hinge assemblies comprise a swinging rod, a sliding cover plate and a sliding block, the swinging rod is rotationally connected with the main shaft assembly and is in sliding connection with the sliding block, in this way, in the rotating process of the swinging rod relative to the main shaft, the sliding block can be driven to rotate relative to the main shaft assembly and also slide relative to the swinging rod so as to adjust the width of the hinge mechanism to adapt to the deformation of the screen, the sliding cover plate is in sliding connection with the main shaft assembly and is connected with the swinging rod, and in the rotating process of the swinging rod relative to the main shaft assembly, the sliding cover plate can be driven to slide on the main shaft assembly. The sliding cover plate, the shell and the sliding block are controlled to move through the swing rod, when the folding equipment is in a folded state, the sliding cover plate slides to a position between the main shaft assembly and the shell, so that the two sliding cover plates, the two shells and the main shaft assembly form a continuous and complete shell of the folding equipment, when the folding equipment is in a fully unfolded state, the folding equipment is converted from the folded state to the unfolded state, the sliding cover plate slides close to the main shaft assembly, the shells move close to the main shaft assembly, the two shells can move to the outer side of the main shaft assembly to finally cover the main shaft assembly, when the folding equipment is in the semi-unfolded state with a certain angle, the two shells and the main shaft assembly can form the continuous and complete shell of the folding equipment, and when the folding equipment is in the fully unfolded state, the two shells can form the continuous and complete shell of the folding equipment. Therefore, the swing rod controls the sliding cover plate, the shell and the sliding block to move, so that the folding function of the folding equipment can be realized, and the continuous and complete shell can be formed in any state.

It should be understood that the structure of the individual components and the connection relationships between the components in the apparatus shown in fig. 1-11 are for illustrative purposes only and that any alternative structure of components that function in the same manner as each component is within the scope of the embodiments of the present application.

It should be understood that in embodiments of the present application, the terms "connected," "fixedly connected," "rotatably connected," and "contacted," are to be construed broadly, unless explicitly stated or limited otherwise. The specific meaning of the various terms described above in embodiments of the present application will be understood by those of ordinary skill in the art as the case may be.

For example, the connection may be a fixed connection, a rotating connection, a flexible connection, a mobile connection, an integrated connection, an electrical connection, or the like, or may be directly connected, or may be indirectly connected through an intermediate medium, or may be internal communication between two elements or an interaction relationship between two elements.

For example, for a "fixed connection" it may be that one element is directly or indirectly fixedly connected to another element, and the fixed connection may include mechanical connection, welding, bonding, etc., where the mechanical connection may include riveting, bolting, screwing, keying, snap-in connection, plugging, etc., and the bonding may include adhesive bonding, solvent bonding, etc.

For example, the explanation of "contact" may be that one element is in direct contact with another element or in indirect contact, and furthermore, the contact between two elements described in the embodiments of the present application may be understood as a contact within an allowable range of mounting error, and there may be a small gap due to the mounting error.

It should also be understood that the description of embodiments of the present application as "parallel" or "perpendicular" may be understood as "approximately parallel" or "approximately perpendicular".

It will be further understood that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, are merely for convenience in describing and simplifying the description of the present application based on the orientation or positional relationship shown in the drawings, and do not denote or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the application.

It should be noted that the terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying a number of technical features being indicated. Features defining "first", "second" may include one or more such features, either explicitly or implicitly.

In embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "at least part of an element" means part or all of the element. "and/or" describes an association of associated objects, meaning that there may be three relationships, e.g., A and/or B, and that there may be A alone, both A and B, and B alone, where A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
