Description

Technical Field

[0001] This utility model relates to the field of camera module technology, and in particular to a camera module PCB circuit board. Background Technology

[0002] Currently, camera modules are commonly used in various fields such as mobile terminals, entertainment terminals, industrial control terminals, financial terminals, medical terminals, and vehicle terminals for image information acquisition and transmission. These modules, combined with the control unit of the main unit, enable intelligent implementation of corresponding functions. Furthermore, with the development of electronic technology, various smart terminals are moving towards integration, miniaturization, and functional diversification, resulting in a significant reduction in internal installation space. Therefore, due to the limitations of internal installation space, circuit boards and other components must be as small and thin as possible. However, when circuit boards are narrow and thin, installation stability becomes a concern, and they are also susceptible to vibration and other factors, further reducing installation and operational stability. This, in turn, affects the quality of image information acquisition and the effectiveness of subsequent use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a camera module PCB circuit board that is small in size, has good fixation after installation, and has a certain shock resistance.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a camera module PCB circuit board, including a strip-shaped PCB circuit board, a camera and a microphone are fixed on the front side of the PCB circuit board, the camera and the microphone are respectively electrically connected to a circuit module for signal processing, the circuit module is arranged on the PCB circuit board on both sides of the camera and a shielding cover is respectively attached to the outside of the circuit board, a PCB connector electrically connected to the circuit module is also fixed on the PCB circuit board, a shock-absorbing adhesive layer is fixed on the back side of the PCB circuit board, and the surface of the shock-absorbing adhesive layer is covered with a removable protective film layer, and a connecting screw hole is arranged through the PCB circuit board.

[0005] As a preferred technical solution, the circuit module is driven by a status indicator light, and a light hole is provided through the shielding cover corresponding to the status indicator light.

[0006] As a preferred technical solution, the width of the PCB circuit board is ≤5mm and the thickness is ≤1mm.

[0007] As a preferred technical solution, the connecting screw holes are provided in two locations, located on both sides of the long axis of the PCB circuit board.

[0008] As a preferred technical solution, the connecting screw hole is provided through the shielding cover.

[0009] As a preferred technical solution, the shock-absorbing adhesive layer is provided to cover the entire back side of the PCB circuit board.

[0010] As an improvement to the above technical solution, the protective film layer is provided with a removal operation part extending to the outside of the shock-absorbing adhesive layer.

[0011] As an improvement to the above technical solution, an installation gap is formed between the shield and the front side of the PCB circuit board to accommodate the circuit module, and an escaping notch is formed at each of the four corners of the shield, which is connected to the installation gap.

[0012] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: the formed PCB circuit board is relatively thin and narrow, and the shielding cover can improve its rigidity to a certain extent to prevent the circuit board from bending and breaking. During use, the entire board can be installed and fixed in the terminal device by connecting screw holes and screws. While strengthening the fixation with the shock-absorbing adhesive layer, a certain shock-absorbing effect can also be obtained to prevent excessive vibration from affecting the stability of the camera and microphone. The protective film layer covers and protects the shock-absorbing adhesive layer before the board is installed and used, so as to facilitate storage and ensure the adhesion of the shock-absorbing adhesive layer. The overall embodiment forms a narrow and thin strip structure, which is especially suitable for use in smart terminals with narrow internal installation gaps. Attached Figure Description

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. It is needless to say that those of ordinary skill in the art can recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the drawings and the description are illustrative in nature and are not intended to limit the protection scope of the claims.

[0019] As Figure 1 , Figure 2 and Figure 3 shown, the camera module PCB circuit board can be installed and applied to various smart terminals for collecting information such as video, audio, and images, so as to cooperate with the processor in the smart terminal to complete the implementation of corresponding tasks or functions. Specifically, it includes a PCB circuit substrate 1 in a rectangular strip structure. A camera 2 and a microphone 3 are fixed on the front surface of the PCB circuit substrate 1. The camera 2 and the microphone 3 are respectively electrically connected to a circuit module for signal processing. The circuit module is disposed on the PCB circuit substrate 1 on both sides of the camera 2 and shield covers 4 are respectively buckled on the outside. Among them, two microphones 3 are provided and are disposed on the PCB circuit substrate 1 on both sides of the camera 2 to pick up sound signals more accurately. The shield cover 4 is mainly used to block external electromagnetic interference, and can also physically protect some electronic components in the circuit module, and improve the overall strength of the PCB circuit board to a certain extent.

[0020] In this embodiment, an installation gap for accommodating the circuit module is formed between the shield cover 4 and the front surface of the PCB circuit substrate 1. Escape air cutouts 5 communicating with the installation gap are respectively formed at the four corners of the shield cover 4. The circuit module generates heat during operation, causing a thermal pressure to be formed in the installation gap, and the internal supporting sensors and some electronic components are sensitive to temperature. For example, the thermal pressure environment will affect the accuracy of sensor signal detection, etc. By providing the escape air cutouts 5, rapid pressure relief can be achieved for the installation gap to eliminate the influence of thermal pressure and ensure the stable operation of the circuit module. The circuit module supporting the camera 2 and the microphone 3 generally includes an image sensor, an image signal processor, a power management chip, a clock circuit, a protection circuit, a control bus, etc. In addition, pads and other basic structures are also disposed on the PCB circuit substrate 1. The above are all well-known contents to those of ordinary skill in the art and will not be described in detail here.

[0021] The PCB circuit board 1 is also fixed with a PCB connector 6 that is electrically connected to the circuit module. The image information obtained by the camera 2 and the sound information picked up by the microphone 3 are respectively sent to the circuit module for processing. The resulting processed signal can be sent to the processor in the smart terminal through the PCB connector 6, forming important technical information for the smart terminal to complete tasks or realize corresponding functions. At the same time, it can also receive relevant information from the processor in the smart terminal to realize parameter adjustments of the camera 2 and the microphone 3.

[0022] The circuit module is connected to a status indicator light 7, and a light hole is provided through the shielding cover 4 corresponding to the status indicator light 7 to indicate the working status of the entire circuit board. If the status indicator light 7 is set as a red-green indicator light, the circuit module controls the operating voltage of the status indicator light 7 so that it displays green under normal circuit board conditions and red under abnormal conditions. Furthermore, during the installation and use of the circuit board, the status indicator light 7 can be directly observed from the smart terminal, allowing for timely detection of the circuit board's status and prompt handling of any abnormalities, thereby helping to ensure the reliability of the smart terminal's operation.

[0023] In this embodiment, the PCB circuit board 1 has a width ≤ 5mm and a thickness ≤ 1mm, resulting in a relatively thin and narrow PCB circuit board, suitable for use in various smart terminals with limited internal mounting clearance. Connecting screw holes 8 are provided through the PCB circuit board 1, which cooperate with screws to secure the circuit board within the smart terminal. Specifically, two connecting screw holes 8 are provided, located on both sides of the long axis of the PCB circuit board 1, allowing for installation of the circuit board with minimal screws. The connecting screw holes 8 are correspondingly arranged through the shielding cover 4, and the strength of the shielding cover 4 provides support for the screws, ensuring a secure installation of the entire circuit board.

[0024] A shock-absorbing adhesive layer 9 is fixed to the back of the PCB circuit board 1, and the surface of the shock-absorbing adhesive layer 9 is covered with a removable protective film layer 10. The shock-absorbing adhesive layer 9 enhances the fixation of the circuit board to a certain extent. Furthermore, due to its flexibility, it also provides shock absorption to prevent excessive vibration from affecting the stability of the camera 2 and the microphone 3, thereby indirectly ensuring the stability of acquired image and sound signals. To maximize the bonding effect, the shock-absorbing adhesive layer 9 covers the entire back of the PCB circuit board 1.

[0025] In this embodiment, a removal operation section 11 extending to the outside of the shock-absorbing adhesive layer 9 is provided on the protective film layer 10. Before use, the shock-absorbing adhesive layer 9 is covered for protection to prevent adhesion between circuit board products. It also prevents dust and other foreign matter from adhering to the shock-absorbing adhesive layer 9, which could affect its fixing effect after use. During installation, the protective film layer 10 can be quickly removed using the removal operation section 11, improving installation efficiency.

[0026] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
