Description
Technical Field
[0001] This utility model belongs to the field of lens module technology and relates to a bracket structure for a camera lens module. Background Technology
[0002] A camera module with focusing function typically includes a lens, a voice coil motor, a lens mount, a filter, an imaging chip, and a circuit board. The lens is mounted inside the voice coil motor, which drives the lens to extend and retract to achieve focusing. The lens mount has a light-transmitting hole that runs through the upper and lower surfaces. The filter is located inside the light-transmitting hole of the lens mount. The voice coil motor is bonded to one end of the lens mount, and the end of the lens mount away from the voice coil motor is bonded to the circuit board. The imaging chip is located on the circuit board, directly opposite the light-transmitting hole of the lens mount.
[0003] In existing technologies, the lens bracket and circuit board are glued together. However, this connection method is prone to shaking during collisions and bumps, which affects the overall focusing accuracy and precision. Therefore, we have designed a bracket structure for the camera lens module. Summary of the Invention
[0004] The purpose of this utility model is to provide a bracket structure for a camera lens module to solve the problems mentioned in the background art.
[0005] The objective of this utility model can be achieved through the following technical solution: A bracket structure for a camera lens module includes a rectangular plate and a light-transmitting hole on the rectangular plate. A terminal plate recess is provided on one side of the rectangular plate, and a terminal connecting plate is installed inside the terminal plate recess. Two circuit board pins are installed at the bottom of the terminal connecting plate, and rubber insulating rings are installed at the bottom of the two circuit board pins. A first anti-collision strip is provided on one side of the top of the rectangular plate, and two second anti-collision strips are provided on the other side of the top of the rectangular plate. The ends of the two second anti-collision strips are respectively connected to the outer edge of the light-transmitting hole.
[0006] In the aforementioned bracket structure for a camera lens module, a side limiting platform is also included. A limiting rod is installed at one end of the side limiting platform. A channel is opened on one side of the rectangular plate. The channel is connected to the limiting rod and allows the limiting rod to extend to the light-transmitting hole.
[0007] In the aforementioned bracket structure for a camera lens module, a circuit board bonding part is installed at the bottom end of the side limiting platform.
[0008] In the aforementioned bracket structure for a camera lens module, the thickness of the first anti-collision strip is equal to the thickness of the second anti-collision strip, and the first anti-collision strip is less than half the thickness of the rectangular plate.
[0009] In the aforementioned bracket structure for a camera lens module, four light-limiting recesses connected to a rectangular plate are provided along the edge of the light-transmitting hole.
[0010] In the aforementioned bracket structure for a camera lens module, the terminal connection board is an insulated PCB structure.
[0011] Compared with the prior art, the advantages of the bracket structure of the camera lens module of this utility model are as follows: By opening a terminal plate recess on one side of the rectangular plate, a terminal connecting plate is installed inside the terminal plate recess, and two circuit board pins are installed at the bottom of the terminal connecting plate. Rubber insulating rings are installed at the bottom of the two circuit board pins. This facilitates quick positioning and installation onto the circuit board without the need for adhesive, ensuring good connection stability and positional installation accuracy, and making it convenient to use. At the same time, a limiting pressure rod, a side limiting platform, and a circuit board bonding part are set. The limiting pressure rod abuts against the light sheet located inside the light-transmitting hole, which facilitates better limitation of the position of the light sheet and ensures good firmness and stability.

Detailed Implementation
[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0017] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a bracket structure for a camera lens module;
[0018] Example 1: The bracket includes a rectangular plate 1 and a light-transmitting hole 2 located on the rectangular plate 1. A terminal plate recess 6 is provided on one side of the rectangular plate 1. A terminal connecting plate 7 is installed inside the terminal plate recess 6. The terminal connecting plate 7 is an insulated PCB structure. Two circuit board pins 8 are installed at the bottom of the terminal connecting plate 7. Rubber insulating rings 9 are installed at the bottom of the two circuit board pins 8. Four light-limiting recesses 3 connected to the rectangular plate 1 are provided at the edge of the light-transmitting hole 2.
[0019] Furthermore, based on Embodiment 1, it also includes a side limiting platform 12, one end of which is equipped with a limiting pressure rod 11, and a channel 10 is opened on one side of the rectangular plate 1. The channel 10 is connected to the limiting pressure rod 11 and the limiting pressure rod 11 extends to the light-transmitting hole 2. A circuit board bonding part 13 is installed at the bottom end of the side limiting platform 12.
[0020] The above scheme is designed to limit the position of the light sheet located inside the light-transmitting hole 2, thereby better defining the position of the light sheet and ensuring good firmness and stability.
[0021] In the above scheme, in order to reduce the impact effect of the rectangular plate 1, a first anti-collision strip 4 is provided on one side of the top of the rectangular plate 1, and two second anti-collision strips 5 are provided on the other side of the top of the rectangular plate 1. The ends of the two second anti-collision strips 5 are respectively connected to the outer edge of the light-transmitting hole 2. The thickness of the first anti-collision strip 4 is equal to the thickness of the second anti-collision strip 5, and the first anti-collision strip 4 is less than half the thickness of the rectangular plate 1.
[0022] In use: Two holes for matching circuit board pins 8 are made on the circuit board. The two circuit board pins 8 at the bottom of the terminal connecting plate 7 are installed in the corresponding holes, so that the rectangular plate 1 is located on the circuit board. The rubber insulating rings 9 at the bottom of the two circuit board pins 8 make the rectangular plate 1 more secure. Four light sheet limiting recesses 3 are provided on the edge of the light-transmitting hole 2, which are connected to the rectangular plate 1. This gives the light sheet inside the light-transmitting hole 2 good stability. At the same time, the limiting pressure rod 11 is inserted into the channel 10 and extends to the light-transmitting hole 2, abutting against the edge of the light sheet to ensure good stability. This solution facilitates quick positioning and installation on the circuit board without the need for adhesive, ensuring good connection stability and positional installation accuracy, and is easy to use.
