Description

Technical Field

[0001] This utility model relates to the field of camera focusing technology, specifically a focusing mechanism for a mobile phone camera module. Background Technology

[0002] With the rapid development of the mobile phone industry, digital video recording functions on mobile phones are becoming increasingly popular among users, and the requirements for camera resolution and clarity are gradually increasing. Mobile phone digital video recording functions involve capturing still images or recording short videos using a built-in digital camera. As an important additional function of mobile phones, its technology and effects are becoming increasingly mature and sophisticated.

[0003] A search revealed prior art publication number CN204334762U, which discloses a standard head for a mobile phone camera module. The head includes a support with a filter, motor, and lens arranged sequentially upwards. A step is provided within a rectangular frame formed by a limiting block on the top surface of the support, and the filter is adhered to the step with UV adhesive. The motor and lens are connected by threads. An octagonal prism is provided on the top surface of the motor, which can cooperate with a claw plate on the top of the lens for automatic focusing. A groove is provided on the bottom surface of the motor to cooperate with the limiting block on the top surface of the support. The bottom surface of the motor and the top surface of the support are welded together after installation. This utility model combines the specifications of the wafer, support, motor, and lens, satisfying optical parameters and structural assembly requirements. It reduces the overall height of the module, simplifies the production process of traditional camera modules, and offers flexible and convenient assembly. Its widespread application has good economic and social benefits.

[0004] However, existing mobile phone camera modules cannot adjust the camera angle. This fixed-angle design results in insufficient flexibility during shooting, making it unable to adapt to different shooting scenarios and needs. For example, when shooting landscapes, portraits, or low-angle objects, users may need to adjust the phone's angle to achieve a better composition, but because the camera's angle is fixed, this causes inconvenience. Furthermore, in some special scenarios, such as shooting close-up objects or performing macro photography, fixed-angle cameras cannot achieve autofocus or require users to manually adjust the phone's position to focus, affecting the convenience and efficiency of shooting.

[0005] Therefore, based on the above-mentioned search and combined with existing technologies, a mobile phone camera module focusing mechanism is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a focusing mechanism for a mobile phone camera module to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A focusing mechanism for a mobile phone camera module includes: a substrate, a capacitor-resistor assembly disposed on the top surface of the substrate, a wafer disposed on the capacitor-resistor assembly, a bracket disposed on the substrate, a motor fixedly mounted on the inner wall of the bracket, a connecting post disposed inside the motor, and a camera body disposed above the connecting post; and an adjustment mechanism disposed between the connecting post and the camera body, and used to adjust the angle of the camera body.

[0009] Preferably, the adjusting mechanism includes: a connecting plate, which is disposed above the connecting column. A circular groove is formed on the top surface of the connecting column.

[0013] Preferably, the top surface of the connecting plate is connected to the bottom surface of the camera body, and the diameter of the connecting plate is smaller than the diameter of the circular groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In one typical implementation of this application, please refer to Figures 1-5 As shown, a mobile phone camera module focusing mechanism includes: a substrate 1, a capacitor-resistor assembly 2 is disposed on the top surface of the substrate 1, a wafer 3 is disposed on the capacitor-resistor assembly 2, a bracket 4 is disposed on the substrate 1, a motor 5 is fixedly installed on the inner wall of the bracket 4, a connecting post 6 is disposed inside the motor 5, and a camera body 7 is disposed above the connecting post 6.

[0024] An adjustment mechanism is provided between the connecting column 6 and the camera body 7, and is used to adjust the angle of the camera body 7.

[0025] The adjustment mechanism includes: a connecting plate 10, which is positioned above the connecting column 6. A circular groove 9 is formed on the top surface of the connecting column 6. Four sliding grooves 11 are formed on the inner wall of the circular groove 9. Limiting rods 12 are fixedly installed on the inner walls of each of the four sliding grooves 11. Iron blocks 13 are provided on the outer surfaces of each of the four limiting rods 12, and the iron blocks 13 slide within the sliding grooves 11. The adjustment mechanism also includes: four cylinders 16, which are fixedly installed on the side walls of the four iron blocks 13. A ball 17 is fixedly installed on the top surface of each of the four cylinders 16. The adjustment mechanism also includes a driving component.

[0026] The driving components include: electromagnets 14, four electromagnets 14 are provided and fixedly installed in four sliding grooves 11 respectively, and springs 15 are provided between the four electromagnets 14 and the four iron blocks 13. A driving chip 8 is fixedly installed on the top surface of the substrate 1.

[0027] The bottom surface of the connecting plate 10 has four spherical grooves 18, and four spheres 17 are movably connected to the four spherical grooves 18 respectively.

[0028] Based on the above features, the angle of the connecting plate 10 can be adjusted. Specifically, when it is necessary to shift the connecting plate 10 to the corresponding position, it is only necessary to activate the corresponding electromagnet 14. When the electromagnet 14 is activated, it will attract the iron block 13. When the iron block 13 moves, both the cylinder 16 and the ball 17 move, pulling the connecting plate 10 and causing it to shift. During the downward movement of the iron block 13, the spring 15 will be compressed and deformed. In addition, the current applied to the electromagnet 14 can be controlled to control the distance the iron block 13 descends.

[0029] The top surface of the connecting plate 10 is connected to the bottom surface of the camera body 7. The diameter of the connecting plate 10 is smaller than the diameter of the circular groove 9. Through the above features, when the connecting plate 10 is adjusted, the camera body 7 connected to the connecting plate 10 will also be adjusted synchronously.

[0030] Working principle:

[0031] In use, when the angle of the camera body 7 needs to be adjusted, the drive chip 8 sends a control signal to the electromagnet 14. When the connecting plate 10 needs to be shifted in a certain direction, the corresponding electromagnet 14 is activated. For example, if the connecting plate 10 is to be shifted to the left, the electromagnet 14 on the left is energized and generates a magnetic field, thereby attracting the iron block 13 to move in the direction of the electromagnet 14. When the iron block 13 moves, due to its cooperation with the limiting rod 12, the iron block 13 can slide along the limiting rod 12 in the sliding groove 11. As the iron block 13 moves, the cylinder 16 fixed on its side wall and the ball 17 at the top of the cylinder 16 also move. The ball 17 is located in the spherical groove 18 on the bottom surface of the connecting plate 10. When the ball 17 moves, it will cause the connecting plate 10 to shift. During the downward movement of the iron block 13, its bottom will compress the spring 15, causing the spring 15 to deform and store elastic potential energy. By controlling the current flowing through the electromagnet 14, the displacement distance of the iron block 13 can be adjusted, thereby precisely controlling the angle of the connecting plate 10. The top surface of the connecting plate 10 is connected to the bottom surface of the camera body 7, so when the angle of the connecting plate 10 changes, the angle of the camera body 7 also changes accordingly, thus achieving the focusing function.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
