[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figures 1-4 This utility model provides a camera lens protection mechanism, including a camera body 1, a lens body 2 fixedly connected to one side of the camera body 1, and a protective component covering the outside of the lens body 2. The protective component includes a protective frame 3 fitted over the lens body 2, and an inner ring 301 fixedly connected inside the protective frame 3, which is wrapped around the outside of the lens body 2. A cushioning cotton is filled between the inner ring 301 and the protective frame 3. Two symmetrically arranged baffles 308 are slidably connected to the side of the protective frame 3 facing the shooting end of the lens body 2. T-slots 309 are provided at the top and bottom of the side of the protective frame 3 facing the shooting end of the lens body 2. The top and bottom of the opposite ends of the two baffles 308 facing the protective frame 3 are provided with... The T-shaped slider is adapted to the T-slot 309. The bottom of the protective frame 3 is fixedly connected to the drive motor 302. The output shaft of the drive motor 302 is fixedly connected to the transmission screw 303. The external thread of the transmission screw 303 is connected to the movable frame 304. The interior of both sides of the protective frame 3 is provided with a sliding groove 305 for the top of both sides of the movable frame 304 to slide. The top of both ends of the movable frame 304 facing the baffle 308 is fixedly connected to the movable plate 306. The top and bottom of each movable plate 306 are rotatably connected to the linkage plate 307. The other ends of the two linkage plates 307 on the same movable plate 306 are rotatably connected to the top and bottom of the baffle 308 on the same side of the same movable plate 306 near the other baffle 308.

[0024] When the camera is not in shooting mode, the two baffles 308 are in a closed state, completely blocking the shooting end of the lens body 2. At this time, the T-shaped sliders on the top and bottom of the side of the baffle 308 facing the protective frame 3 are located in the T-shaped grooves 309 on the top and bottom of the side of the protective frame 3 facing the shooting end of the lens body 2, which stabilizes the position of the baffle 308 and prevents dust, water vapor and other substances from entering the lens, thus protecting the lens.

[0025] When shooting is required, the drive motor 302 fixedly connected to the bottom of the protective frame 3 is started. The output shaft of the drive motor 302 starts to rotate, driving the transmission screw 303 fixedly connected to it to rotate. Since the moving frame 304 is externally threaded to the transmission screw 303, and the top of both sides of the moving frame 304 slides in the sliding grooves 305 opened inside the protective frame 3 on both sides, under the action of threaded transmission and the limiting action of the sliding grooves 305, the moving frame 304 will move along the axial direction of the transmission screw 303. The moving plates 306 fixedly connected to the top of both ends of the moving frame 304 facing the baffle 308 will move accordingly. The top and bottom of each moving plate 306 are rotatably connected to the linkage plate 307, and the other end of the linkage plate 307 is rotatably connected to the top and bottom of the baffle 308 on the same side as it. As the moving plate 306 moves, the linkage plate 307 will rotate, thereby pushing the two baffles 308 to slide to both sides along the T-slot 309, realizing the opening of the baffles 308, exposing the shooting end of the lens body 2 for shooting operation.

[0026] After the shooting is completed, the drive motor 302 is controlled to rotate in the opposite direction, the transmission screw 303 also rotates in the opposite direction, the moving frame 304 moves in the opposite direction along the transmission screw 303, driving the moving plate 306 and the linkage plate 307 to move in the opposite direction, the linkage plate 307 pulls the two baffles 308 to slide along the T-slot 309 towards the middle until the two baffles 308 close again, blocking the shooting end of the lens body 2 again, and continuing to protect the lens;

[0027] The protective frame 3 is fitted on the outside of the lens body 2. The inner ring 301 tightly wraps the lens body 2, and the space between the two is filled with buffer cotton. It can wrap the lens body 2 in all directions and provide a solid protective barrier for the lens. The buffer cotton can effectively absorb and disperse the impact energy from external collisions, drops and other accidents, greatly reduce the damage caused by vibration to the precision lens, and extend the service life of the lens.

[0028] The transmission system, consisting of a drive motor 302, a transmission screw 303, a moving frame 304, a moving plate 306, and a linkage plate 307, enables the automatic opening and closing of the two baffles 308. Users do not need to operate them manually. The baffles 308 can be quickly opened when shooting is needed and quickly closed after shooting. This avoids the problem of missing shooting opportunities due to cumbersome manual operation and improves shooting efficiency. The automatic opening and closing design allows the shooting end of the lens body 2 to be promptly covered by the baffles 308 when not in use, greatly reducing the time the lens is exposed to dangerous environments such as dust and moisture, and effectively protecting the optical performance of the lens.

[0029] In this embodiment, a connecting component is provided on the side of the protective component facing the camera body 1. The connecting component includes a connecting frame 4. Connecting hook plates 401 are fixedly connected to both sides of the connecting frame 4 facing the camera body 1. The top and bottom of the camera body 1 are provided with grooves that are adapted to the connecting hook plates 401. An arc-shaped groove is opened on the top of the connecting frame 4. A locking clamp 402 is rotatably connected to one side of the top of the connecting frame 4. A connecting plate 403 with a central hole is fixedly connected to the side of the connecting frame 4 facing the protective frame 3. Connecting parts 4031 are fixedly connected to the four corners of the connecting plate 403. The protective frame 3 is fixedly connected to the connecting parts 4031 by bolts.

[0030] The protective frame 3 is placed over the lens body 2. At this time, the inner ring 301 fixed inside the protective frame 3 will tightly wrap around the lens body 2. The cushioning cotton filled between the inner ring 301 and the protective frame 3 can buffer the external impact force in subsequent use, providing initial protection for the lens body 2. The connecting frame 4 is placed facing the protective frame 3. The connecting parts 4031 at the four corners of the protective frame 3 and the connecting plate 403 are fixedly connected by bolts, so that the connecting frame 4 is firmly installed on the side of the protective frame 3 facing the camera body 1. The connecting hook plates 401 on both sides of the connecting frame 4 facing the camera body 1 are aligned with the grooves on the top and bottom of the camera body 1. The connecting hook plates 401 are inserted into the grooves to achieve initial positioning. Then, the locking clamp 402 rotatably connected on the top side of the connecting frame 4 is rotated, so that the locking clamp 402 rotates around the rotation point until the locking clamp 402 is engaged in the appropriate position on the top of the camera body 1, completing the firm connection between the connecting component and the camera body 1, and thus making the entire protective component firmly installed outside the camera lens.

[0031] The working principle and usage process of this utility model are as follows: First, the protective frame 3 is placed on the outside of the lens body 2. Its inner ring 301 tightly wraps the lens. The buffer cotton between the inner ring 301 and the protective frame 3 can buffer external impact. The connecting frame 4 is placed facing the protective frame 3. The connecting parts 4031 at the four corners of the protective frame 3 and the connecting plate 403 are fixed with bolts so that the connecting frame 4 is stably installed on the side of the protective frame 3 facing the camera body 1. The connecting hook plates 401 on both sides of the connecting frame 4 are inserted into the matching grooves at the top and bottom of the camera body 1 for initial positioning. Then, the locking clamp 402 at the top of the connecting frame 4 is rotated to fasten the top of the camera body 1, thus completing the firm connection between the connecting component and the camera body 1, so that the entire protective component is stably installed outside the camera lens.

[0032] When the two baffles 308 are closed, the T-shaped slider of the baffle 308 is located in the T-shaped groove 309 of the protective frame 3, which stabilizes the position of the baffle 308 and prevents dust and moisture from entering the lens.

[0033] Start the bottom drive motor 302 of the protective frame 3. Its output shaft drives the transmission screw 303 to rotate. The moving frame 304 moves under the limit of the threaded transmission and the slide groove 305, which drives the moving plate 306 to move. The linkage plate 307 rotates and pushes the two baffles 308 to slide open along the T-slot 309 to both sides, exposing the lens shooting end.

[0034] The drive motor 302 is controlled to rotate in the opposite direction, the transmission screw 303 rotates in the opposite direction, the moving frame 304 moves in the opposite direction, which drives the moving plate 306 and the linkage plate 307 to move in the opposite direction. The linkage plate 307 pulls the two baffles 308 to slide and close along the T-slot 309 towards the middle, continuing to protect the lens.

[0035] It should be noted that in the above solution, a connecting wire is fixedly connected to one side of the drive motor 302, and a switch is provided on the outside of the connecting wire. The other end of the connecting wire is provided with a USB interface. This is existing technology, so it has not been described in detail.
