Description

Technical Field

[0001] The utility model relates to the field of photographic components, in particular to a camera module base. Background Art

[0002] At present, conventional camera modules require glue to be used in the assembly of the circuit board and the base. After bonding, the glue needs to be baked at a high temperature of 85°C for half an hour to solidify the glue. However, since the base is mostly made of plastic, the base and glue will undergo slight deformation due to thermal expansion after being exposed to high temperatures, which will cause changes in the original optical properties of the entire module, such as the focus point, and affect the final imaging effect of the module.

[0003] Therefore, there is an urgent need to propose a camera module base that can maintain the optical properties of the module after installing a circuit board. Utility Model Content

[0022] 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.

[0023] The present application proposes a camera module base, in which a circular clamping assembly 30 is arranged inside the shell 10 to clamp the circuit board 20 in the circular clamping assembly 30. The present application does not require glue bonding and high-temperature baking of the shell 10 and the circuit board 20 to fix the circuit board 20. The present application directly clamps the circuit board 20 by setting the circular clamping assembly 30, thereby maintaining good optical properties of the module and simplifying the process of installing the circuit board 20.

[0024] Specifically, see Figure 1, including: a shell 10 and a circuit board 20. The upper bottom surface and the lower bottom surface of the shell 10 are both provided with openings, the interior is hollow, and a receiving cavity 11 is provided. A circular clamping component 30 is provided in the receiving cavity 11, and the circuit board 20 is clamped in the circular clamping component 30.

[0025] Furthermore, the circular clamping assembly 30 is disposed at the lower end of the accommodating cavity 11, and the upper end is used to connect with the photographic lens 50, so as to protect the lens 50 from being worn by the desktop or workbench during placement.

[0026] Furthermore, the annular clamping assembly 30 includes a first annular piece 31 and a second annular piece 32. The first annular piece 31 extends from the bottom of the accommodating cavity 11 in a radial direction, and the second annular piece 32 extends from the accommodating cavity 11 above the first annular piece 31. The first annular piece 31, the second annular piece 32 and the shell 10 are combined to form a mounting groove. The circuit board 20 is clamped in the mounting groove. There is no need for glue bonding and high-temperature baking. The circuit board 20 is directly clamped by the mounting groove to fix the circuit board 20.

[0027] Because the conventional thickness of FPC is 0.12 mm and the conventional thickness of PCB is 1 mm, the distance between the first annular piece 31 and the second annular piece 32 in the embodiment of the present application is 0.14 mm or 1.1 mm, so that the FPC or PCB can be stably fixed in the installation groove to avoid shaking.

[0028] In one embodiment, see Figure 1 The top of the housing 10 is provided with an internal thread, which can be screwed with the external thread on the photographic lens 50, so as to facilitate the installation of the lens 50.

[0029] In order to facilitate the user to grasp and assemble the lens 50, the housing 10 is cylindrical and hollow inside to accommodate other electronic components.

[0030] In one embodiment, the housing 10 includes a first housing and a second housing, the first housing and the second housing are snap-fitted in their radial direction, and the snap-fitting of the first housing and the second housing is between the first annular piece 31 and the second annular piece 32, so as to facilitate the assembly of the circuit board 20 in the mounting groove and to facilitate the removal and maintenance of the circuit board 20. Similarly, in another embodiment, the housing 10 includes a first housing and a second housing, the first housing and the second housing are snap-fitted in their axial direction.

[0031] Since there are errors in the specifications of the circuit board 20 , an elastic material layer 40 is provided between the circuit board 20 and the annular clamping assembly 30 to prevent the circuit board 20 from shaking in the installation slot and affecting the user's experience.

[0032] In addition, an adhesive layer is provided between the circuit board 20 and the annular clamping assembly 30 , and the circuit board 20 and the annular clamping assembly 30 are adhered to each other through the adhesive layer, so that the circuit board 20 is more firmly clamped in the mounting groove.

[0033] 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.
