[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0022] A two-way locking base structure, referring to Figure 1, including a base 10, the base 10 includes a base body 11 and a lens barrel 12 arranged on the base body 11, the bottom of the base body 11 is open, and one end of the camera module is used to extend into the base 10, and the lens of the camera module extends into the base 10 and is accommodated in the lens barrel 12.
[0023] Reference Figure 1 and Figure 2 The lower end surface of the base 10 is connected to the bottom plate of the camera module, and the upper end surface of the base 10 is used to connect to the whole machine. The two outer walls of the base 10 are both provided with a two-way locking structure for two-way locking. The two two-way locking structures are arranged on the two opposite outer walls of the base 10. The lower end of the two-way locking structure is connected to the bottom plate of the camera module, and the upper end of the two-way locking structure is connected to the whole machine. The two-way locking structure includes a locking seat 20 and a screw hole penetrating the locking seat 20. The locking seat 20 and the base 10 are integrally formed, and the screw hole is vertically penetrated in the locking seat 20. The screw hole is arranged as an upper and lower through hole.
[0024] Reference Figure 1 A partition plate 30 is provided in the screw hole for separation. The partition plate 30 is located in the middle of the screw hole. The partition plate 30 divides the screw hole into two independent upper screw holes 21 and lower screw holes 22. The upper screw hole 21 is located above the partition plate 30, and the upper end of the upper screw hole 21 is an opening. The lower screw hole 22 is located below the partition plate 30, and the lower end of the lower screw hole 22 is an opening. The inner walls of the upper screw hole 21 and the lower screw hole 22 are both provided with threads along the length direction.
[0025] Further, refer to Figure 1 The partition plate 30 is made of metal material, and the thickness of the partition plate 30 is 0.5 mm. The partition plate 30 is used to prevent the upper screw hole 21 and the lower screw hole 22 from colliding with each other after being combined with the screws, causing one of the screws to loosen or fall off.
[0026] Reference Figure 1 The lower screw hole 22 of the base 10 is locked with the bottom plate of the camera module, and a self-tapping screw 40 is inserted into the lower screw hole 22 to lock the bottom plate of the camera module with the base 10.
[0027] Reference Figure 1 The upper screw hole 21 of the base 10 is used to lock with the whole machine, and a self-tapping screw 40 is also inserted into the upper screw hole 21 to fix the whole machine and the camera module.
[0028] Further, refer to Figure 1 The wall thickness of the upper screw hole 21 and the lower screw hole 22 are both greater than 1 mm to prevent the self-tapping screw 40 from being squeezed, deformed or broken when the base 10 is locked with the self-tapping screw 40.
[0029] Reference Figure 1 When the self-tapping screw 40 is locked with the upper screw hole 21 or the lower screw hole 22, the self-tapping screw 40 is locked into the upper screw hole 21 or the lower screw hole 22 for at least three circles to ensure the stability of the locking.
[0030] Furthermore, in order to prevent the upper screw holes 21 of the base 10 from causing deformation of the bottom plate of the camera module after the whole machine is installed with self-tapping screws 40, when the bottom plate of the camera module is a PCB structure, the thickness of the bottom plate should be more than 1.6 mm. When the bottom plate of the camera module is an FPC structure, a steel sheet reinforcement plate with a thickness of more than 0.3 mm needs to be added to the bottom plate to increase the deformation resistance of the bottom plate of the camera module.
[0031] Reference Figure 1 By setting a two-way locking structure, the base 10 is first locked with the bottom plate of the camera module, and the self-tapping screw 40 is passed through the bottom plate of the camera module and inserted into the lower screw hole 22 to lock it. When the camera module is assembled with the whole machine, the self-tapping screw 40 is inserted into the upper screw hole 21 to fix the camera module and the whole machine. The two-way locking structure facilitates the two-way locking of the camera module and the whole machine, thereby ensuring that the camera module and the whole machine can be firmly fixed to avoid displacement.
[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
