As shown in Figures 3 and 4, the sliding mechanism includes a lower slide 20 with a guide rail 13, and an upper slide 10 that is slidably connected to the lower slide 20 through the guide rail 13, and two slides are installed between the lower slide 20 and the upper slide 10. An elastic element 30, the elastic element 30 includes a first connecting arm 31, a second connecting arm 32 and an arc segment 33, the first connecting arm 31 is connected with the upper slide plate 10, and the second connecting arm 32 is connected with the upper slide plate 10 The lower plate 20 is connected, and the arc segment 33 connects the first connecting arm 31 and the second connecting arm 32 . The elastic elements 30 are arranged oppositely, and can be in a compressed state or a stretched state at the same time.

The elastic body 30 is a spring. Furthermore, the spring can be wound with a very thin steel wire to make a high-strength heterosexual spring. The spring has a simple structure, which not only ensures sufficient spring force but also enables the spring to occupy less space and reduce the thickness of the structure.

The upper slide plate 10 and the lower slide plate 20 are respectively provided with spring connection holes 12 and 22 , and the springs can be connected between the upper slide plate 10 and the lower slide plate 20 with the fixing column 40 .

Corresponding to the guide rails 23 on the opposite sides of the lower slide 20, guide grooves 13 are installed on the opposite sides of the upper slide 10. When assembling, one end of the spring is fixed on the spring connection hole 12 of the upper slide 10 with a fixing column 40. , and the other end is fixed on the spring connection hole 22 of the lower plate 20 with a fixed column 40, and then the guide rails 23 on both sides of the lower plate 20 are placed in the corresponding guide grooves 13 of the upper slide plate 10 to complete the assembly of the entire sliding mechanism.

In the initial position shown in Figure 3, the upper slide 10 is at the lower end of the lower slide 20, and the spring is in a free state or slightly stretched. state. Push the upper sliding plate 10 upwards, compress the spring, and the spring stores elastic force. When the spring connecting holes 12 and 22 are at the same horizontal position, the spring reaches the maximum compression amount, and the elastic force of the spring reaches the maximum. After that, the spring releases the elastic force, and the compression amount decreases. Small, the upper slide plate 10 continues to slide under the effect of the elastic force of the spring until the spring returns to a free state or slightly stretched state by the compressed state, and the upper slide plate 10 is at the upper end of the lower slide plate. During the whole process, the shape transition of the spring 30 is smooth, the stress is uniform during the deformation process, and the structure is stable.

Please refer to FIG. 8 . FIG. 8 schematically shows a mobile phone with a sliding mechanism of the present invention, which includes a main body 60 and a cover 50 .

The upper sliding plate 10 and the lower sliding plate 20 of the sliding mechanism are respectively provided with a fixing hole 11 and a fixing hole 21.

On the main body 60. The above-mentioned assembly process is simple, and at the same time, the whole assembly process ensures good flatness of the spring and uniform force distribution, so the above-mentioned mobile phone has a good sliding feel.

As shown in Figure 8, it is a schematic diagram of the closed state of the mobile phone. It is assumed that this is the initial state, that is, the cover body 50 completely covers the main body 60. At this time, the upper slide plate 10 is at the lower end of the lower slide plate 20, and the spring is in a free state or slightly The stretched state ensures that the cover body 50 is stable relative to the main body 60 .

When an external force is applied to the cover body 50 along the guide rail 20, the cover body 50 slides upward relative to the main body 60 along the guide rail 23, and the cover body 50 drives the upper slide plate of the sliding mechanism to move upward together, compressing the spring, and the spring stores elastic force.

As shown in Figure 8, the cover body of the mobile phone slides for a certain distance and is in an intermediate state. At this time, the spring connection holes 12 and 22 are at the same horizontal position, the spring reaches the maximum compression, and the elastic force of the spring reaches the maximum.

Remove the external force applied on the cover body 50 at this time, the spring releases the elastic force, and the compression amount decreases. The state returns to a free state or a slightly stretched state, and the upper slide plate 10 is at the upper end of the lower slide plate. At this moment, the cover body 50 reaches the final position of opening, and the operation area on the main body 60, such as the keyboard area, is exposed, and the mobile phone can be controlled. Operation of various functions, as shown in FIG. 9 is a schematic diagram of the mobile phone in an open state. During the whole process, the shape transition of the spring is smooth, the force is uniform during the deformation process, and the structure is stable.

In order to make the cover 50 no longer slide after the operating area of the main body 60 is fully exposed, it is only necessary to adjust the length of the guide rail 23 .

The sliding of the cover body 50 of the mobile phone back to the initial state and the opening of the cover body 50 is a reverse process. The closing movement of the cover body 50 can be soft and brisk, so details will not be described here.
