DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figure 1-6As shown, the utility model provides a technical solution: a self-cleaning device for automobile cameras and laser radars, comprising a camera end 1, a disk cover 3 is fixedly sleeved on the right end of the camera end 1, a glass retaining ring 2 is rotatably inserted inside the disk cover 3, the left side of the glass retaining ring 2 is in sliding contact with the right end of the camera end 1, an end cover 5 is fixedly connected to the right end of the disk cover 3, the inner and outer diameter difference of the glass retaining ring 2 is greater than the right end diameter of the camera end 1, so that the glass retaining ring 2 can completely block the camera end 1.
[0028] A water spray structure 4 is provided between the glass retaining ring 2 and the end cover 5. The water spray structure 4 is installed inside the disk cover 3. The inner ring of the glass retaining ring 2 is provided with a power soft wheel 6 in contact. The right end of the power soft wheel 6 rotates and penetrates the left side of the end cover 5. The inner ring side of the glass retaining ring 2 is a groove ring structure, which is convenient for the power soft wheel 6 to rotate and drive the glass retaining ring 2 to rotate by contacting the groove ring structure of the glass retaining ring 2. A motor 7 is fixedly installed on the right side of the end cover 5. The right end of the power soft wheel 6 is fixedly connected to the output end of the motor 7. The water spray structure 4 includes a water spray plate 401, a water supply pipe 403, and an inner cavity plate 40 4 and the movable plugging plate 402, the end cover 5 is fixedly sleeved on the outer surface of the water supply pipe 403, the inner cavity plate 404 is fixedly sleeved on the left end of the water supply pipe 403, the right side of the water spray plate 401 is fixedly connected to the left side of the inner cavity plate 404, the movable plugging plate 402 is slidably inserted between the inner cavity plate 404 and the water spray plate 401, and the side of the movable plugging plate 402 close to the axis of the disk cover 3 is fixedly connected with a friction ring 405, the friction ring 405 is rotatably sleeved on the inner ring surface of the disk cover 3, and the friction wheel 406 is frictionally contacted below the friction ring 405, and the friction wheel 406 is fixedly sleeved on the power soft wheel 6 The outer surface of the friction collar 405 is fixedly connected with a stabilizing block 11 on the right side, and a track plate 12 is slidably sleeved on the outer surface of the stabilizing block 11. The right side of the track plate 12 is fixedly connected to the left side of the end cover 5. When the friction collar 405 moves, the stabilizing block 11 is driven to slide in the track plate 12, and the moving track of the movable blocking plate 402 is limited. The upper surface of the friction collar 405 is fixedly connected with a spring telescopic rod 407, and the other end of the spring telescopic rod 407 is fixedly connected to the flat plate 9 located above. A through groove 408 is provided on the right side of the movable blocking plate 402. The right side of the water spray plate 401 is fixedly connected to the outer surface of the friction collar 405. A water inlet hole 409 is provided on the side and inside the inner cavity plate 404. The friction force between the friction wheel 406 and the friction ring 405 ensures that when the friction wheel 406 rotates, it can contact with the friction ring 405 to push the friction ring 405 to rotate, push the spring telescopic rod 407 to compress, and drive the movable blocking plate 402 to move, so that the through groove 408 connects the water supply pipe 403 and the water inlet hole 409. The shape of the through groove 408 is arc-shaped, which increases the time for the through groove 408 to be connected with the water inlet hole 409 and the water supply pipe 403. The arc axis of the through groove 408 is coaxially arranged with the glass retaining ring 2.
[0029] The outer surface of the power soft wheel 6 is fixedly sleeved with a gear wheel 15, and an elastic plate 16 is meshed above the gear wheel 15. The other end of the elastic plate 16 is fixedly connected to the disc cover 3. When the motor 7 drives the power soft wheel 6 to rotate, the gear wheel 15 pushes the elastic plate 16 to bend elastically and continuously displace it. When the motor 7 stops, the elastic plate 16 meshes with the gear wheel 15 to ensure that when the spring telescopic rod 407 pushes the friction ring 405 to reset, the friction ring 405 will not push the friction wheel 406 to rotate. The friction between the friction wheel 406 and the friction ring 405 increases the time for the friction ring 405 to reset, and increases the time for the through groove 408 to communicate with the water supply pipe 403 and the water inlet hole 409.
[0030] The bottom surface of the disk cover 3 is rotatably connected with a through-hole sealing plate 8, and a positioning plate 14 is arranged below the right end of the through-hole sealing plate 8. The positioning plate 14 is slidably plugged into the outer screen of the disk cover 3, and clean water can be discharged through the through-hole sealing plate 8. When the positioning plate 14 is located below the through-hole sealing plate 8, the through-hole sealing plate 8 blocks the disk cover 3. After pushing the positioning plate 14 and the through-hole sealing plate 8 to be misaligned, the through-hole sealing plate 8 can be opened to clean the impurities remaining in the disk cover 3. The right side of the disk cover 3 and the front and rear sides of the camera end 1 are fixedly plugged with a flat plate 9, and there is a gap between the flat plate 9 and the glass retaining ring 2. The right end of the flat plate 9 is fixedly connected to the left side of the end cover 5. Next, a water-absorbing sponge 10 is installed inside the disk cover 3 and between the glass retaining ring 2 and the end cover 5. The water-absorbing sponge 10 can absorb water stains on the surface of the glass retaining ring 2 that has moved out of the disk cover 3 to prevent water stains from remaining on the surface of the glass retaining ring 2 and affecting the shooting when the glass retaining ring 2 rotates to the right side of the camera end 1. The inner ring surface of the glass retaining ring 2 is in rotational contact with two stabilizing wheels 13, and the two stabilizing wheels 13 are both rotationally connected to the left side surface of the end cover 5. The power soft wheel 6 and the two stabilizing wheels 13 are distributed in a circular array around the axis of the glass retaining ring 2. The glass retaining ring 2 and the disk cover 3 are coaxially arranged, and the two stabilizing wheels 13 increase the stability of the glass retaining ring 2 when it rotates.
[0031] Working principle: after the glass retaining ring 2 on the right side of the camera end 1 is blurred, the motor 7 drives the glass retaining ring 2 to rotate through the power soft wheel 6, and the toothed wheel 15 continuously pushes the elastic plate 16 to deform and dislocate elastically, and at the same time, the friction wheel 406 rotates by contacting with the friction ring 405, and the friction ring 405 and the movable blocking plate 402 are driven to move by the friction force, so that the through groove 408 is connected with the water supply pipe 403 and the water inlet hole 409, ensuring that when the glass retaining ring 2 is active, the water spray plate 401 can spray water outward in time to clean the glass retaining ring 2 to be cleaned, and when the glass retaining ring 2 is moved, the water spray plate 401 can spray water outward in time to clean the glass retaining ring 2 to be cleaned. When the flat plate 9 on the left side moves out, the absorbent sponge 10 absorbs the moisture on the surface of the glass retaining ring 2 to prevent water stains from remaining on the surface of the glass retaining ring 2 and affecting the shooting when the glass retaining ring 2 rotates to the right side of the camera terminal 1. After the clean glass retaining ring 2 rotates to the right side of the camera terminal 1, the motor 7 is stopped, the power soft wheel 6 stops rotating, and the spring telescopic rod 407 gradually pushes the friction ring 405 and the movable blocking plate 402 to reset, so that the movable blocking plate 402 blocks the water inlet hole 409 again, so that the water spray plate 401 can delay stopping the water spraying, thereby increasing the cleaning effect of the glass retaining ring 2.
