[0020] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0021] like Figures 1 to 5 As shown, a dustproof and waterproof integrated lens includes a housing 1. A lens frame 4 is mounted inside the housing 1, and a front lens group 5 is mounted inside the lens frame 4. Furthermore, a P-IRIS aperture and a rear lens group 2 are sequentially mounted inside the housing 1 behind the lens frame 4.

[0022] like Figures 1 to 5 As shown, the lens frame 4 is movably mounted inside the housing 1. Specifically, the integrated lens includes a mounting plate 401, a motor 402, a lead screw 403, a slider 404, and guide posts 405. Two guide posts 405 are fixedly disposed between the housing 1 and the cover plate 6. The lens frame 4 is movably fitted onto the two guide posts 405, and the two guide posts 405 are located on the left and right sides of the lens frame 4, respectively. More specifically, the two ends of the guide posts 405 are inserted into the sleeves of the housing 1 and the cover plate 6, thereby fixing the guide posts 405 between the housing 1 and the cover plate 6. Of course, the number of guide posts 405 is not limited to two.

[0023] The lens frame 4 includes, but is not limited to, a slider 404 detachably fixedly connected by screws; the housing 1 includes, but is not limited to, a mounting plate 401 detachably fixedly connected by screws, a lead screw 403 rotatably connected to the mounting plate 401, and a motor 402 for rotating the lead screw 403, while the lead screw 403 is threadedly connected to the slider 404. When the motor 402 drives the lead screw 403 to rotate, since the lead screw 403 is threadedly connected to the slider 404, the slider 404 moves back and forth accordingly, thereby causing the lens frame 4 and the front lens group 5 to move back and forth, realizing the floating focusing function of the integrated camera lens.

[0024] like Figures 1 to 5 As shown, the integrated camera lens also includes a cover plate 6, a lens 7, an outer cover 8, a first sealing ring 91, and a second sealing ring 92.

[0025] The cover plate 6 is detachably and fixedly connected to the front end of the housing 1 by screws, and the lens 7 is fixedly sealed to the hollow area of ​​the cover plate 6.

[0026] Specifically, the front end of the cover plate 6 has a first annular recess 61 and a second annular recess 62. The second annular recess 62 is located outside the first annular recess 61, and the two are connected. During assembly, the edge of the lens 7 is fixedly adhered to the first annular recess 61 with strong adhesive, and then the second annular recess 62 is filled with waterproof sealant (not shown in the figure) to seal the gap between the cover plate 6 and the lens 7. It can be seen that a double sealing measure is used between the lens 7 and the cover plate 6 to ensure the airtightness of the assembly. Using the first annular recess 61 and the second annular recess 62 for positioning and assembly improves assembly accuracy and helps to improve the airtightness.

[0027] like Figures 1 to 5 As shown, the outer cover 8 is detachably and fixedly fitted onto the outside of the housing 1 and the cover plate 6, and the lens 7 is exposed through the hollow area at the front end of the outer cover 8; the front end of the outer cover 8 is sealed to the cover plate 6 between the outer periphery of the lens 7 and the cover plate 6 by a first sealing ring 91, and the rear end of the outer cover 8 is sealed to the housing 1 by a second sealing ring 92.

[0028] Specifically, the housing 1 is provided with three blind holes 81, and the housing 1 is secured to the blind holes 81 from back to front with screws.

[0029] The housing 1 is also provided with a second annular platform 11, and the rear end of the outer cover 8 is provided with a fourth annular recess 82. The front end of the cover plate 6 is also provided with a third annular recess 63, which is located outside the second annular recess 62 and the two are not connected. The front end of the outer cover 8 is provided with a first annular platform 84. First, the cover plate 6 is fixedly connected to the housing 1, and then the outer cover 8 is fixedly connected to the housing 1. After the outer cover 8 is fixedly connected to the housing 1, the second sealing ring 92 seals and abuts between the fourth annular recess 82 and the second annular platform 11; at the same time, the first sealing ring 91 seals and abuts between the third annular recess 63 and the first annular platform 84.

[0030] Preferably, the front end of the outer cover 8 is provided with a plurality of reinforcing ribs 85 arranged in a ring to connect the first annular platform 84. The reinforcing ribs 85 strengthen the first annular platform 84, making the first annular platform 84 less prone to deformation due to the contact of the first sealing ring 91, thus making it more secure and providing better sealing.

[0031] Preferably, the outer cover 8 forms an annular boss 83 on the inner edge of the fourth annular recess 82 for positioning and abutting the second sealing ring 92, making the assembly of the second sealing ring 92 simpler and further improving the sealing performance. Of course, the height of the annular boss 83 should be lower than the height of the second sealing ring 92.

[0032] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
