Description

Technical Field

[0001] This invention relates to the field of camera technology, and specifically to an infrared high-definition camera based on dynamic privacy occlusion control. Background Technology

[0002] A camera, also known as a computer camera, computer eye, or electronic eye, is an image acquisition device widely used in video conferencing, telemedicine, and real-time monitoring. When unattended, a camera can monitor its surroundings from all angles. Users often have conflicting needs: they want thorough monitoring but also want their privacy protected.

[0003] Therefore, it is necessary to set up a shielding component to dynamically shield the camera lens for privacy. However, if the position of the shielding component is not fixed accurately, it may not be able to completely cover the lens's field of view, creating a risk of privacy leakage. If the shielding component vibrates or shifts during operation due to insecure fixing, it will affect the mechanical life.

[0004] Meanwhile, prolonged hanging of the camera can cause dust, smoke, or moisture to contaminate the lens surface, resulting in blurry images.

[0005] In summary, there is a need to develop an infrared high-definition camera based on dynamic privacy occlusion control, which combines precise positioning and reliable fixation to solve the above problems. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an infrared high-definition camera based on dynamic privacy occlusion control, specifically comprising: Mounting plate, camera, lens, housing, with a detachable clamping mechanism mounted on the outer surface of the housing; The infrared high-definition camera based on dynamic privacy occlusion control also includes: The device includes a privacy shielding component, which can be precisely adjusted to rotate from top to bottom to provide privacy protection for the lens's field of view. The shielding component is mounted on the inner surface of the clamping mechanism. The device secures the camera to the wall surface via a mounting plate. The lens is quadrilateral with rounded corners. The outer casing is longer than the camera, and its top extends beyond the camera body to accommodate the clamping mechanism and the privacy shielding component. The device can control the rotation of the privacy shielding component to dynamically block the lens's exterior privacy.

[0007] In the initial stage, the clamping mechanism, shielding components, and reverse cleaning components of this device will not affect the normal shooting operation of the camera. At the same time, a certain space is reserved between the top of the camera and the upper surface of the wall. This space does not need to be too long, just enough to facilitate the operation of the shielding components later.

[0008] Furthermore, the clamping mechanism includes a standard clamping plate with a standard clamping groove on its outer surface. Two arc-shaped plates are symmetrically mounted on both sides of the standard clamping plate. An arc-shaped clamping plate is fixed to the side of each arc-shaped plate away from the standard clamping plate, and its outer surface has an arc-shaped clamping groove. Bolts are threaded to the center of the upper surfaces of both the standard clamping plate and the arc-shaped clamping plates. The curvature of the two arc-shaped clamping plates matches the curvature of the outer shell, facilitating installation on the outer surface of the shell. The clamping mechanism possesses sufficient strength and rigidity, and, together with bolts and other parts, firmly fixes the shielding component and the reverse cleaning component inside the shielding component to the outer surface of the shell, ensuring the installation stability of the entire device.

[0009] Furthermore, the standard clamping groove and the arc-shaped clamping groove have the same shape as the surface of the contact area with the outer shell, and the size of the opening of the standard clamping groove and the arc-shaped clamping groove are consistent with the thickness of the outer shell.

[0010] Furthermore, the shielding component includes a support base, on the inner wall of which a small motor is mounted. A connecting plate is fixedly connected to the output end of the small motor, and a shielding cover is mounted on the top of the connecting plate. Power modules are mounted on the edges of both sides of the inner wall of the shielding cover. The outer surface of the support base is fixedly connected to the side of a standard clamping plate closest to the small motor. The support base secures and supports the small motor, and the power modules can be installed inside the shielding cover, facilitating disassembly when replacement is needed.

[0011] Furthermore, a reverse cleaning component is fixedly attached to the inner surface of the shielding component. This reverse cleaning component moves from the center of the lens to both sides to clean the outer surface of the lens. The reverse cleaning component includes an electric telescopic rod, with a limiting component fixedly attached to its extended end. A striking component is fixedly attached to the outer surface of the limiting component, and a fixing rod is slidably connected to the inner wall of the limiting component. A cleaning brush plate is mounted on the top of the fixing rod, and an insertion hole is provided on its outer surface. The end of the electric telescopic rod away from the limiting component is installed on the inner wall of the shielding cover. The electric telescopic rod is symmetrically arranged on both sides of the center of the shielding cover. The electric telescopic rod can be electrically connected to the output terminal of the power module via a wire, which is embedded in the inner wall of the shielding cover for cable distribution. Except for standard components such as the camera, lens, small motor, and electric telescopic rod, which use the same materials as existing components, other components such as the connecting plate and shielding plate are made of plastic to reduce the overall weight of the device.

[0012] Furthermore, all the cleaning brushes on the cleaning brush plate are soft-bristled, and the edge shape of the cleaning brush plate is designed to conform to the corners of the lens surface. The soft-bristled brushes can slide and clean the lens surface, and the soft bristles prevent damage to the lens surface during the sliding cleaning process.

[0013] Furthermore, the limiting component includes a limiting block, the inner wall of which is provided with a mounting hole, an alignment rod slidably connected to the inner wall of the limiting block, a compression spring mounted on the upper surface of the alignment rod, a limiting rod mounted at the center of the top of the alignment rod, and a pull ring mounted on the top of the limiting rod. The limiting block can fix the extended end of the electric telescopic rod to the fixing rod and the cleaning brush, and precisely limit the position and orientation of the cleaning brush through the limiting block.

[0014] Furthermore, the mounting holes on the inner wall of the limiting block are fixedly connected to the circular holes at the protruding end of the electric telescopic rod by bolts and nuts.

[0015] Furthermore, the outer surface of the alignment rod is slidably connected to the inner wall of the insertion hole, the end of the compression spring away from the alignment rod is fixedly connected to the inner wall of the limiting block, the outer surface of the limiting rod is slidably connected to the inner wall of the limiting block, and the pull rings are symmetrically arranged on both sides of the fixing rod. The extended end of the electric telescopic rod has a circular hole, allowing it to slide into the inner wall of the limiting block and limit its position, preventing left and right rotation. Bolts and nuts further secure the limiting block, preventing it from detaching from the surface of the electric telescopic rod.

[0016] Furthermore, the size of the insertion hole is consistent with the size of the alignment rod, and the circular hole on the extended end surface of the electric telescopic rod is consistent with the size of the mounting hole.

[0017] Furthermore, the striking component includes a bent rod with a limiting groove formed on its outer surface. A striking plate is rotatably connected to the inner wall of the limiting groove. The side of the bent rod closest to the limiting rod is fixedly connected to the outer surface of the limiting block. The striking plate can be made of aluminum alloy, which combines strength and lightweight properties, ensuring both structural strength and portability.

[0018] The beneficial effects of this invention are as follows: The rotation of the cover in the blocking component effectively provides privacy protection for the lens surface; the clamping mechanism ensures stable installation and quick disassembly of both the blocking component and the reverse cleaning component, while guaranteeing precise positioning of both components on the lens surface during subsequent operations; the reverse movement of the two cleaning brush plates in the reverse cleaning component allows the cleaning brushes to slide from the center of the lens to both sides, preventing the brushes from scraping in a straight line from one direction to another, thus avoiding excessively long dust movement paths on the lens surface and preventing damage to the lens surface. While friction damage may occur, the symmetrical design of the cleaning brush plate and its shape that matches the edge of the lens effectively avoid cleaning dead spots. Through the engagement of the alignment rod and fixing rod in the limiting component and the synergistic action of the limiting block, the cleaning brush plate can be quickly installed and removed. On the one hand, this effectively prevents cleaning failure caused by incorrect installation angle or positional deviation of the cleaning brush plate. On the other hand, after the cleaning brush has been working for a long time, the soft bristles may harden. The limiting component allows for manual replacement of the cleaning brush plate, improving the ability to quickly change the cleaning brush. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] For the first embodiment, please refer to... Figures 1-4 This invention relates to an infrared high-definition camera based on dynamic privacy occlusion control, specifically comprising: Mounting plate 1, camera 2, lens 3, housing 4, the outer surface of housing 4 is equipped with a detachable clamping mechanism 5; The infrared high-definition camera based on dynamic privacy occlusion control also includes: The shielding component 6 is precisely adjustable in its downward rotation angle to provide privacy shielding for the field of view of the lens 3. The shielding component 6 is mounted on the inner surface of the clamping mechanism 5. The device uses a mounting plate 1 to fix the camera 2 to the wall surface. The lens 3 is quadrilateral with rounded corners. The outer casing 4 is longer than the camera 2, and its top extends beyond the camera 2 body to accommodate the clamping mechanism 5 and the shielding component 6. This device can control the shielding component 6 to dynamically shield the exterior of the lens 3.

[0023] In the initial stage, the clamping mechanism 5, the blocking component 6, and the reverse cleaning component 7 set in this device will not affect the normal shooting operation of the camera 2. At the same time, a certain space length is reserved between the top of the camera 2 and the upper surface of the wall. This space length does not need to be too long, just enough to facilitate the operation of the blocking component 6 later.

[0024] The clamping mechanism 5 includes a standard clamping plate 51 with a standard clamping groove 52 on its outer surface. Arc-shaped plates 53 are symmetrically mounted on both sides of the standard clamping plate 51. An arc-shaped clamping plate 54 is fixed to the side of the arc-shaped plate 53 away from the standard clamping plate 51. An arc-shaped clamping groove 55 is formed on the outer surface of the arc-shaped clamping plate 54. Bolts are threaded to the center of the upper surfaces of both the standard clamping plate 51 and the arc-shaped clamping plate 54. The bending shape of the two arc-shaped clamping plates 54 matches the bending shape of the outer shell 4, facilitating installation on the outer surface of the outer shell 4. The clamping mechanism 5 possesses sufficient strength and rigidity, and together with bolts and other parts, firmly fixes the shielding component 6 and the reverse cleaning component 7 inside the shielding component 6 to the outer surface of the outer shell 4, ensuring the installation stability of the entire device.

[0025] The standard clamping groove 52 and the arc-shaped clamping groove 55 have the same shape as the surface of the contact part with the outer shell 4, and the size of the groove opening of the standard clamping groove 52 and the arc-shaped clamping groove 55 is consistent with the thickness of the outer shell 4.

[0026] The shielding component 6 includes a support base 61, a small motor 62 is mounted on the inner wall of the support base 61, a connecting plate 63 is fixedly connected to the output end of the small motor 62, a shielding cover 64 is mounted on the top of the connecting plate 63, and power modules 65 are mounted on the edges of both sides of the inner wall of the shielding cover 64. The outer surface of the support base 61 is fixedly connected to the side of the standard clamping plate 51 near the small motor 62, and the small motor 62 is fixed and supported by the support base 61. The power modules 65 can be installed inside the shielding cover 64, and can be easily disassembled when the power modules 65 need to be replaced.

[0027] The specific work process is as follows: First, the device securely mounts the shielding component 6 and the reverse cleaning component 7 onto the surface of the housing 4 via the clamping mechanism 5, without affecting the shooting operation of the camera 2.

[0028] Before installing the device, the operator aligns the openings of the standard clamping groove 52 and the arc-shaped clamping groove 55 with the protruding part of the outer shell 4, and pushes the standard clamping plate 51 and the arc-shaped clamping plate 54 to slide inward along the outer surface of the outer shell 4 until the end face of the outer shell 4 is tightly fitted against the inner wall of the standard clamping groove 52 and the arc-shaped clamping groove 55. Since the size of the openings of the standard clamping groove 52 and the arc-shaped clamping groove 55 is the same as the thickness of the outer shell 4, the standard clamping plate 51 and the arc-shaped clamping plate 54 can no longer move left or right or tilt along the surface of the outer shell 4. At this time, the installer connects three bolts into the inner wall of the standard clamping plate 51 and the arc-shaped clamping plate 54 respectively, until the bottom of the bolts is tightly fitted against the upper surface of the outer shell 4, thus achieving a firm clamping.

[0029] The size and shape of the standard clamping groove 52 and the arc-shaped clamping groove 55 are designed for the edge curvature and thickness of the outer shell 4. The arc-shaped clamping plates 54 on both sides are indispensable and can limit the position of the clamping mechanism 5, further ensuring that the shielding cover 64 in the shielding component 6 and the reverse cleaning component 7 are in the correct position, such as ensuring that the shielding cover 64 is in the center, so that the shielding cover 64 can be correctly aligned with the front of the lens 3 during subsequent rotation.

[0030] In the initial stage, the cover 64 is in a flipped-up position, which does not obstruct the operation of the camera 2. When it is necessary to cover the lens 3, the cover 64 can accurately cover the front position of the lens 3 of the camera 2, effectively blocking the lens 3. At the same time, the clamping mechanism 5 is detachable. In different usage scenarios, such as when a camera 2 is damaged, it can be quickly disassembled and the entire device can be transferred to other cameras 2 of the same type for use. This avoids the trouble of disassembly or the inability to disassemble, which would prevent the transfer and reuse of a damaged camera 2.

[0031] When camera 2 is operating normally and shooting is required, the blocking component 6 is in the position as follows: Figure 2 The position shown will not affect the operation of camera 2. When camera 2 stops working, the blocking component 6 is activated to block the lens 3 of camera 2 for privacy. The small motor 62 starts and drives the connecting plate 63 and the blocking cover 64 to rotate counterclockwise towards the side closer to the lens 3 through the output end. After they have rotated to a certain angle, until the blocking cover 64 is in a vertical position and the opening side of the blocking cover 64 faces camera 2, the small motor 62 stops. At this time, the blocking cover 64 can effectively block the front of the lens. The blocking cover 64 is larger than the lens 3, and the lens 3 is recessed into the inner surface of camera 2. Therefore, the blocking cover 64 will not touch the lens 3, and replacement will not cause squeezing damage to the lens 3. When the lens 3 of camera 2 is working normally, the small motor 62 starts again and controls the connecting plate 63 and the blocking cover 64 to rotate clockwise to reset until the blocking cover 64 rotates to the original position angle.

[0032] Second embodiment, please refer to Figures 1-10This invention relates to an infrared high-definition camera based on dynamic privacy occlusion control. A reverse cleaning component 7 is fixedly attached to the inner surface of the occlusion component 6. The reverse cleaning component 7 moves from the center of the lens 3 to both sides to clean the outer surface of the lens 3. The reverse cleaning component 7 includes an electric telescopic rod 71. A limiting component 72 is fixedly attached to the extended end of the electric telescopic rod 71. A striking component 73 is fixedly attached to the outer surface of the limiting component 72. A fixing rod 74 is slidably connected to the inner wall of the limiting component 72. A cleaning brush plate 75 is installed at the top of the fixing rod 74. An insertion hole 76 is provided on the outer surface of the fixing rod 74. The end of the electric telescopic rod 71 away from the limiting component 72 is installed on the inner wall of the occlusion cover 64. The electric telescopic rods 71 ​​are symmetrically arranged on both sides of the center of the occlusion cover 64. The electric telescopic rods 71 ​​can be electrically connected to the output terminal of a power module 65 via wires. The wires are embedded in the inner wall of the occlusion cover 64 and distributed in a cabling manner. The power module 65 supplies power to the electric telescopic rods 71. Except for standard components such as camera 2, lens 3, small motor 62, and electric telescopic rod 71, which are made of the same materials as existing components, other components such as connecting plate 63 and cover 64 are made of plastic to reduce the weight of the overall device.

[0033] The cleaning brushes on the cleaning brush plate 75 are all soft-bristled, and the edge shape of the cleaning brush plate 75 is designed to fit the corners of the lens 3 surface. The soft-bristled brushes can slide and clean the lens 3 surface, and due to their soft material, damage to the lens 3 surface can be avoided during the sliding cleaning process.

[0034] The limiting component 72 includes a limiting block 721. The inner wall of the limiting block 721 has a mounting hole 722. An alignment rod 723 is slidably connected to the inner wall of the limiting block 721. A compression spring 724 is mounted on the upper surface of the alignment rod 723. A limiting rod 725 is mounted at the center of the top of the alignment rod 723, and a pull ring 726 is mounted on the top of the limiting rod 725. The limiting block 721 can fix the extended end of the electric telescopic rod 71 to the fixing rod 74 and the cleaning brush, precisely limiting the position and orientation of the cleaning brush.

[0035] The mounting hole 722 on the inner wall of the limiting block 721 is fixedly connected to the circular hole at the protruding end of the electric telescopic rod 71 by bolts and nuts. The outer surface of the alignment rod 723 is slidably connected to the inner wall of the insertion hole 76. The end of the compression spring 724 away from the alignment rod 723 is fixedly connected to the inner wall of the limiting block 721. The outer surface of the limiting rod 725 is slidably connected to the inner wall of the limiting block 721. Pull rings 726 are symmetrically arranged on both sides of the fixing rod 74. The protruding end of the electric telescopic rod 71 has a circular hole, which allows the protruding end of the electric telescopic rod 71 to slide into the inner wall of the limiting block 721 and limit the position of the limiting block 721, preventing it from rotating left or right. The limiting block 721 is further fixed by bolts and nuts to prevent it from detaching from the surface of the electric telescopic rod 71.

[0036] The size of the insertion hole 76 is consistent with the size of the alignment rod 723, and the circular hole on the extended end surface of the electric telescopic rod 71 is consistent with the size of the mounting hole 722.

[0037] The striking component 73 includes a bent rod 731, with a limiting groove 732 formed on its outer surface. A striking plate 733 is rotatably connected to the inner wall of the limiting groove 732. The side of the bent rod 731 closest to the limiting rod 725 is fixedly connected to the outer surface of the limiting block 721. The striking plate 733 can be made of aluminum alloy, which combines strength and lightweight, ensuring both structural strength and portability.

[0038] The specific work process is as follows: When the cover 64 needs to cover the lens 3, it needs to be rotated at a certain angle before it can cover the lens 3. During the rotation, the cover 64 can drive the electric telescopic rod 71, the limiting component 72, the fixing rod 74 and the cleaning brush plate 75 to rotate until the opening of the cover 64 is completely aligned with the orientation of the lens 3. At this time, the cover 64 is in a vertical state, and the brush on the cleaning brush plate 75 is also facing the lens 3. Since two electric telescopic rods 71 ​​are symmetrically arranged, there are left and right symmetrical cleaning brushes on both sides of the center of the lens 3. When the electric telescopic rod 71 extends and retracts, it can slowly drive the limiting component 72, the fixing rod 74 and the two cleaning brush plates 75 to move in opposite directions, so that the brush on the cleaning brush plate 75 can slide and clean along the surface of the lens 3 from the center of the lens 3 to the sides until the edge of the cleaning brush is attached to the edge of the lens 3.

[0039] Since the edges of the cleaning brush plate 75 and the edges of both sides of the lens 3 are all set to the same shape, and the length of the cleaning brush plate 75 is consistent with the height of the lens 3, the cleaning brush can basically completely cover the surface of the lens 3, thereby effectively cleaning the dust on the surface of the lens 3. Therefore, the design of the size and shape of the cleaning brush plate 75 can effectively avoid the problem of incomplete cleaning of dead corners due to the inconsistency between its shape and size and that of the lens 3. Finally, the cleaning brushes on both sides extend from the middle of the lens 3 to both sides for cleaning, which has a better cleaning effect. This avoids the problem of the brush scraping in a straight line from one direction to another, which would cause the dust to move on the surface of the lens 3 for too long, and may cause friction damage to the surface of the lens 3.

[0040] When camera 2 needs to be restarted, the cover 64 and connecting plate 63 are reversed counterclockwise and reset to their original positions under the drive of small motor 62. As the cover 64 begins to move away from the front of lens 3 and rotates, the electric telescopic rods 71 ​​on both sides extend and drive the two cleaning brush plates 75 to move towards each other until the sides of the two cleaning brush plates 75 come into contact. During the movement of the two towards each other, due to the rotation of the cover 64, the cleaning brushes on the cleaning brush plates 75 are not in contact with the surface of lens 3, that is, the cleaning brushes will not slide across the surface of lens 3 again, thus avoiding the situation where the cleaned dust falls back onto the surface of lens 3.

[0041] Combination Figure 5 and Figure 6 It can be concluded that the electric telescopic rod 71 and the fixed rod 74 here are in their initial positions. Figure 5 After the cover 64 rotates to a certain angle, it reaches Figure 6After reaching the desired state, the striking component 73 will also rotate. However, the upper striking plate 733 tends to rotate closer to the fixed rod 74 under the influence of gravity, as the rotation angle changes. That is, the upper striking plate 733 will rotate along the surface of the bent rod 731 towards the side closer to the cleaning brush plate 75, while the lower striking plate 733 will remain attached to the outer surface of the pull ring 726 under the influence of gravity. Therefore, as the cleaning brush plate 75 continues to rotate counterclockwise, the striking plates 733 on both sides of the fixed rod 74 will rotate along the surface of the limiting groove 732 towards the side closer to the cleaning brush plate 75 under the influence of gravity due to the change in angle, until one end of the striking plate 733 is aligned with the cleaning brush plate. 75 impacts the side closer to the fixing rod 74, thereby knocking off the dust adhering to the surface of the cleaning brush. During this process, there is still a certain distance between the cleaning brush and the surface of the lens 3. Due to the rotation angle of the cleaning brush plate 75 at this time, the brush on its surface faces away from the lens 3. The dust that is shaken off will also fall into the space below under gravity, instead of falling onto the surface of the lens 3 on one side. Therefore, by using the angle change between the shielding cover 64 and the cleaning brush plate 75, the striking part 73 can make the striking plate 733 strike the cleaning brush plate 75 due to gravity during the rotation, thereby cleaning off the dust on the surface of the brush and avoiding secondary contamination of the lens 3 during the next use.

[0042] If the cleaning brush is used frequently and in a harsh environment, the soft bristles may harden after prolonged use, leading to cleaning failure. Therefore, cleaning brushes in this condition need to be replaced promptly. First, the operator extends two fingers and pushes the upper and lower pull rings 726 away from each other until the upper and lower alignment rods 723 disengage. During this disengagement, the limiting rod 725 slides along the inner surface of the limiting block 721. The compression spring 724 compresses the alignment rods 723 to resist the operator's pushing force until one end of each alignment rod 723 slides out from the inner wall of the fixing rod 74. At this point, the other hand can remove the fixing rod 74 from the inner surface of the limiting block 721, thus completing the disassembly of the fixing rod 74 and the cleaning brush plate 75. The operator then removes two fingers from the pull rings 726, and the two pull rings 726, limiting rods 725, and alignment rods 723 all return to their original positions under the reset of the compression spring 724.

[0043] When a new cleaning brush plate 75 needs to be replaced, similarly, the operator extends two fingers to push the upper and lower pull rings 726 away from each other, so that the alignment rod 723 does not obstruct the insertion of the fixing rod 74. At this time, the fixing rod 74 is inserted into the inner wall of the limiting block 721, so that the insertion hole 76 on the surface of the fixing rod 74 is completely aligned with the end faces of the upper and lower alignment rods 723. The pull rings 726 are released, and the two alignment rods 723 re-enter the inner wall of the insertion hole 76 under the elasticity of the compression spring 724, thus fixing and limiting the fixing rod 74 and the cleaning brush plate 75. The limiting treatment of the fixing rod 74 by the two alignment rods 723 can prevent the cleaning brush plate 75 from shifting in angle and position when installing a new cleaning brush plate 75, and further avoid the problem that the cleaning brush may not be able to reach the surface of the lens 3 for wiping due to inaccurate angle or position fixation during the subsequent cleaning process of the lens 3.

[0044] The specific workflow is as follows: First, this device achieves stable installation and quick disassembly of the camera 2 through the clamping mechanism 5. The standard clamping groove 52 and the arc-shaped clamping groove 55 are precisely designed for the curvature and thickness of the outer shell 4, ensuring that the clamping plate fits tightly against the outer shell 4, limiting the lateral movement and tilting of the entire device. The bolts further secure the clamping, while ensuring that the blocking component 6 and the reverse cleaning component 7 can be accurately positioned on the surface of the lens 3 in subsequent processes. The detachable nature of the clamping mechanism 5 allows for quick disassembly when the camera 2 used in this device is damaged, enabling its transfer and use among different cameras 2 of the same type, thus improving the utilization rate of the device.

[0045] Secondly, this device uses the opposite movement of two cleaning brush plates 75 to allow the cleaning brushes to slide and clean from the center of the lens 3 to both sides. The symmetrical design of the cleaning brush plates 75 and their shape that matches the lens 3 can effectively avoid cleaning dead corners and improve cleaning ability. At the same time, it can prevent the brush from scraping in a straight line from one direction to another, which would cause dust to move on the surface of the lens 3 for too long and eventually lead to friction damage to the surface of the lens 3.

[0046] After cleaning, during the resetting process of the cover 64, the cleaning brush is disengaged from the surface of the lens 3. At the same time, the cleaning brush plate 75 moves towards each other under the action of the electric telescopic rod 71, which can avoid the problem of secondary pollution. In addition, the tapping component 73 automatically cleans the dust on the brush by using gravity and angle changes, ensuring that the cleaning brush has the ability to continuously clean the lens 3.

[0047] Finally, the device is designed with a limiting component 72, which, through the engagement of the alignment rod 723 and the fixing rod 74 and the synergistic effect of the limiting block 721, ensures the quick installation and removal of the cleaning brush plate 75. On the one hand, it effectively prevents cleaning failure caused by the installation angle and position deviation of the cleaning brush plate 75. On the other hand, after the cleaning brush has been working for a long time, the soft brush may harden. The limiting component 72 can manually replace the cleaning brush plate 75, improving the ability to quickly replace the cleaning brush.
