Therefore, the height of the parts of the driving mechanism 3 that may interfere with the mobile phone body 2 should be lower than the height of the support plate 15.

[0057] In some embodiments, the rotating shaft 32 is positioned in the accommodating cavity through a support 35 , the support 35 is welded in the accommodating cavity, and the rotating shaft 32 is supported by at least two supports 35 .

[0058] The more the number of the supports 35 is, the higher the connection strength between the rotating shaft 32 and the bottom shell 11 is. The specific number of the supports 35 is not limited and can be freely determined according to the length of the rotating shaft 32. The supports 35 are provided with support holes, and rolling bearings can be provided between the rotating shaft 32 and the support holes. The rotating shaft 32 will bear a certain radial force during the rotation process, so a deep groove ball bearing or a radial thrust bearing can be provided between the rotating shaft 32 and the support hole.

[0059] In some embodiments, a guide block 311 is further provided in the accommodating cavity to guide the rack 31. There are two guide blocks 311, which are respectively located on both sides of the rack 31. The cross-sectional shape of the rack 31 is a trapezoid that is wide at the top and narrow at the bottom.

[0061] The handle 34 is disposed outside the accommodating cavity, and the handle 34 is rotatably connected to the bottom shell 11 via a shaft.

[0062] The shaft body can be an integrated structure with the bottom shell 11, and the shaft body can also be provided with a limit block, which is used to prevent the handle 34 from being separated from the shaft body, and the limit block can be fixed to the shaft body by threads.

[0063] Reference Figures 1 to 9 As shown, when the handle 34 rotates in the first direction, the driving slot 341 interferes with the driving column 312, so that the handle 34 drives the rack 31 to move in the first direction, and the handle 34 is then engaged with the gear 321. During the rotation of the gear 321, the shaft 32 rotates synchronously with the gear 321. At this time, the rotation direction of the shaft 32 is the first direction. The shaft 32 and the gear 321 can be an integrated structure, and the shaft 32 and the gear 321 can also be assembled by key connection.

[0064] When the handle 34 rotates in the second direction, the driving slot 341 interferes with the driving column 312, so that the handle 34 drives the rack 31 to move in the second direction, and the handle 34 is then meshed with the gear 321. During the rotation of the gear 321, the shaft 32 moves synchronously with the gear 321. At this time, the rotation direction of the shaft 32 is the second direction.

[0065] In some embodiments, the cover 13 includes a drive seat 131, a cover 132 covering the imaging hole 111, and a connecting portion 133 fixing the cover 132 to the drive seat 131, the screw hole is provided on the drive seat 131, the cover 132, the connecting portion 133, and the drive seat 131 are an integrated structure, and a guide plate for guiding the cover 13 is also provided in the accommodating cavity, and the guide plate and the bottom shell 11 are an integrated structure. A weight-reducing groove for reducing the weight of the connection portion 133 may also be provided on the connection portion 133, and the weight-reducing groove may pass through the connection portion 133.

[0066] In some embodiments, the cover plate 12 is rotatably connected to the bottom shell 11 via a connecting shaft 36, the connecting shaft 36 is rotatably connected to the bottom shell 11, the connecting shaft 36 is installed on the cover plate 12 via a key connection, and the worm gear 33 is installed on the connecting shaft 36 via a key connection.

[0067] In some embodiments, the cover plate 12 is overlapped on the bottom shell 11, and a protective ring 21 for protecting the mobile phone body 2 is also provided in the accommodating cavity. The mobile phone body 2 is clamped on the protective ring 21, and the protective ring 21 is bonded to the side wall of the accommodating cavity. A partition 16 is also provided in the accommodating cavity, and the partition 16 divides the accommodating cavity into a driving cavity and an installation cavity. The mobile phone body 2 is arranged in the installation cavity, and the rack 31 is located in the driving cavity. The partition 16 is provided with a through hole that cooperates with the rotating shaft 32, and the partition 16 and the bottom shell 11 are an integrated structure.

[0068] Specifically, when the rotating shaft 32 moves in the first direction, the worm 322 meshes with the worm wheel 33, causing the worm wheel 33 to rotate in the first direction, thereby causing the cover 12 to rotate in the first direction. At this time, the cover 12 is opened. When the rotating shaft 32 rotates in the first direction, the screw 323 rotates in the first direction. When the screw 323 rotates in the first direction, the cover body 13 moves in the first direction, thereby causing the imaging hole 111 to be opened. The worm 322 can drive the worm wheel 33 to rotate, while the worm wheel 33 cannot drive the worm 322 to rotate. At this time, after the cover 12 is opened, its position is determined. Even if the handle 34 is released, the cover 12 will not rotate automatically, making the mobile phone body 2 easy to operate.

[0069] When the rotating shaft 32 moves in the second direction, the worm 322 meshes with the worm wheel 33, causing the worm wheel 33 to rotate in the second direction, thereby causing the cover plate 12 to rotate in the second direction. At this time, the cover plate 12 is closed. When the rotating shaft 32 rotates in the second direction, the screw 323 rotates in the second direction. When the screw 323 rotates in the second direction, the cover body 13 moves in the second direction, thereby causing the imaging hole 111 to be half-closed.

[0070] The screw 323, the rotating shaft 32, and the worm 322 may be an integrated structure.

[0071] The above describes the subject technical solution and corresponding details of the present invention. It can be understood that the above description is only some implementation plans of the subject technical solution of the present invention, and some details may be omitted during the specific implementation.

[0072] In addition, in some embodiments of the above invention, multiple embodiments may be implemented in combination, and various combinations are not listed one by one due to space limitations. Those skilled in the art can freely combine and implement the above embodiments as needed in specific implementation to obtain a better application experience.
