[0002] A dual-camera fixed-focus lens module refers to a camera module that integrates two fixed-focus lenses. It is typically used in devices such as smartphones to provide better shooting results and functionality. This type of module consists of two cameras, each with its specific focal length and function, working together to improve image quality.
[0003] The dual-camera fixed-focus lens module can simultaneously capture images from both cameras, use parallax to calculate depth information, and achieve functions such as background blur and object segmentation; or merge images from different focal lengths to enhance resolution and dynamic range.
[0004] Existing dual-camera fixed-focus lens modules have the following drawbacks in practical use:
[0005] Currently, dual-camera fixed-focus modules are mostly fixed to the mounting point using multiple screws. This method requires operators to adjust and align the screws so that they are perpendicular to the mounting point before tightening them. This process involves fixing multiple screws one by one, making it quite cumbersome. Utility Model Content

[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.
[0025] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a dual-camera fixed-focus lens module fixed focusing device.
[0026] The specific technical solution includes a mounting plate 1 and a dual-camera fixed-focus lens module 3. The dual-camera fixed-focus lens module 3 is formed by a mounting groove 2 on one side of the mounting plate 1, which contains two fixing mechanisms 4. The dual-camera fixed-focus lens module 3 corresponds to the fixing mechanism 4. The fixing mechanism 4 includes a fixing plate 5, a rotating shaft 11, and a gear 12. The fixing plate 5 has a mounting cavity 6, which is rotatably mounted in the mounting cavity 6. The gear 12 is fixedly mounted around the rotating shaft 11. Two toothed plates 15 are provided on one side of the inner wall of the mounting cavity 6. The toothed plates 15 mesh with the gear 12. A snap-fit plate 16 is fixedly mounted on one end of the toothed plate 15. A snap-fit groove 17 is provided on one side of the snap-fit plate 16. Two insertion slots 7 are provided. Four connecting posts 8 are provided on one side of the dual-camera fixed-focus lens module 3. Insertion blocks 9 are fixedly installed at one end of the connecting posts 8. Insertion blocks 9 are inserted into the mounting cavity 6 through the insertion slots 7. The insertion blocks 9 have slots 10 on their periphery. The snap-fit plate 16 is inserted into the slots 10 through the snap-fit slots 17. Two slide rails 13 are fixedly installed on one side of the inner wall of the mounting cavity 6. The slide rails 13 have a slide groove 14 on one side. A slide plate is fixedly installed on one side of the toothed plate 15. The slide plate is slidably installed in the slide groove 14. The two toothed plates 15 are located on both sides of the toothed plate 15. The insertion blocks 9 are I-shaped and the snap-fit plate 16 is C-shaped. The slide rails 13, slide grooves 14 and slide plate can improve the smoothness of the toothed plate 15 when it moves.
[0027] Reference Figure 4 As shown, a limiting mechanism 18 is provided on one side of the fixed plate 5. The limiting mechanism 18 is connected to the rotating shaft 11. The limiting mechanism 18 includes a rotating shaft 20, a limiting slide rod 22, and a rectangular plate 25. A rotating groove 19 is provided on one side of the fixed plate 5, and the rotating shaft 20 is rotatably installed in the rotating groove 19. A limiting slide groove 21 is provided on one side of the rotating shaft 20, and the limiting slide rod 22 is slidably installed in the limiting slide groove 21. The rectangular plate 25 is fixedly installed at one end of the limiting slide rod 22. A rectangular groove 24 is provided on one side of the fixed plate 5, and the rectangular plate 25 is inserted into the rectangular groove 24. The rotating shaft... 20 is fixedly connected to one end of the rotating shaft 11. A spring 23 is provided between the limiting slide rod 22 and the limiting slide groove 21. Pulling grooves 26 are provided on all sides of the rectangular plate 25. One end of the limiting slide rod 22 is cross-shaped. The limiting slide groove 21 is cross-shaped as a whole. By cooperating with the cross shape at one end of the limiting slide rod 22 and the limiting slide groove 21, the limiting slide rod 22 can only slide in the limiting slide groove 21 and cannot rotate. Thus, the limiting slide rod 22 can drive the rotating shaft 20 to rotate. The pulling groove 26 makes it easy for the user to pull the rectangular plate 25 away from the rectangular groove 24.
[0028] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:
[0029] In use, when fixing and installing the dual-camera fixed-focus lens module 3, the plug 9 on one side of the dual-camera fixed-focus lens module 3 is inserted into the plug slot 7, thereby inserting the plug 9 into the mounting cavity 6. After the plug 9 is fully inserted into the mounting cavity 6, the slot 10 on the periphery of the plug 9 will align with the snap plate 16. Then, the rectangular plate 25 is pulled out of the rectangular slot 24, and the rectangular plate 25 is rotated to drive the limiting slide rod 22 to rotate. The rotation of the limiting slide rod 22 can drive the rotating shaft 20 to rotate through the limiting slide groove 21. The rotation of the rotating shaft 20 can drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 can drive the gear 12 to rotate. The rotation of the two toothed plates 15 can drive the two toothed plates 15 to move synchronously. The synchronous movement of the two toothed plates 15 can drive the two snap-fit plates 16 to move synchronously, so that the two snap-fit plates 16 can synchronously snap with the two plug-in blocks 9 through the snap-fit grooves 17 and 10. By snapping with the two plug-in blocks 9, the plug-in blocks 9 and the connecting post 8 can be fixed and limited, thereby fixing and installing the dual-camera fixed-focus lens module 3. Then, the rectangular plate 25 is inserted into the rectangular groove 24 again, which can limit the rectangular plate 25, the limiting slide bar 22 and the rotating shaft 20, ensuring the stability of the snap-fit plates 16 and the plug-in blocks 9 after they are snapped with each other.

In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
