[0045] The existing camera cleaning device includes a driving mechanism and a belt transmission mechanism; the belt transmission mechanism is located on both sides of the camera lens window, so that the transmission belt of the belt transmission mechanism is located in front of the lens window. The driving mechanism drives the driving wheel of the belt transmission mechanism to rotate, thereby driving the transmission belt and the driven wheel to rotate, so that the cleaning blades on the transmission belt sweep across the surface of the window to clean the window. Because the transmission belt is sleeved on the driving wheel and the driven wheel, the front side of the window is equivalent to having two layers of transmission belts, causing the cleaning device to protrude more from the front side of the window, and thus there is a serious problem of blocking the camera's field of view. Therefore, how to prevent the cleaning device from blocking the camera's field of view is an urgent problem to be solved in the industry.

[0046] In order to solve the problem that the cleaning device in the prior art seriously blocks the camera's field of view, the specific embodiment of the first aspect of the utility model provides a cleaning device. Figures 1 to 5 The cleaning device of the utility model is described in detail. Figure 1 It is a schematic diagram of the assembly structure of the cleaning device and the front face provided by the utility model; Figure 2 yes Figure 1 Schematic diagram of the cross-sectional structure of the AA section; Figure 3 It is a front view structural schematic diagram of the cleaning device provided by the utility model; Figure 4 It is a schematic diagram of the top view of the cleaning device provided by the utility model; Figure 5It is a schematic diagram of the structure of the cleaning roll provided by the utility model when viewed from above.

[0047] like Figures 1 to 4 As shown, in a specific embodiment of the present invention, the cleaning device includes a cleaning belt 100, at least two pulleys 200 and a driving assembly 300;

[0048] The cleaning tape 100 is used to be arranged on the front side of the window 30, and a hollow area 101 corresponding to the window 30 is opened on the cleaning tape 100. Along the length direction of the cleaning tape 100, two pulleys 200 are respectively arranged on both sides of the window 30; one end of the cleaning tape 100 is wound around the pulley 200 on one side of the window 30, and the other end of the cleaning tape 100 is wound around the pulley 200 on the other side of the window 30. The driving component 300 is connected to the pulley 200 on at least one side; when the driving component 300 drives the pulley 200 on one side of the window 30 to rotate to wind the cleaning tape 100, the pulley 200 on the other side of the window 30 releases the cleaning tape 100, so that the non-hollow area of ​​the cleaning tape 100 sweeps across the window 30, thereby cleaning the window 30.

[0049] In this embodiment, pulleys 200 are respectively provided on both sides of the window 30 along the length direction of the cleaning tape 100, and the pulleys 200 on both sides of the window 30 are respectively wound around the two ends of the cleaning tape 100; and then combined with the driving component 300, the driving component 300 is connected to at least the pulley 200 on one side of the window 30, and the driving component 300 is used to drive the pulley 200 on this side to wind the cleaning tape 100, and at the same time, the pulley 200 on the other side of the window 30 releases the cleaning tape 100, so that there is a layer of cleaning tape 100 on the front side of the window 30, and at the same time, the non-hollow area of ​​the cleaning tape 100 is swept across the window 30, so that the window 30 is cleaned. Compared with the solution of cleaning the window 30 by a belt drive mechanism in the prior art, a layer of cleaning tape 100 is provided on the front side of the window 30 of the present embodiment, and pulleys 200 are arranged on both sides of the window 30, thereby reducing the height of the cleaning device protruding from the window 30, thereby solving the problem of the cleaning device in the prior art blocking the camera's field of view.

[0050] like Figure 5 As shown, in some embodiments, the cleaning tape 100 includes a tape body 110 and a cleaning sheet 120;

[0051] The tape body 110 is formed with a hollow area 101, and the two ends of the tape body 110 are respectively wound around the pulleys 200 on both sides. The cleaning sheet 120 is detachably connected to the side of the tape body 110 facing the window 30, and the cleaning sheet 120 is arranged in the non-hollow area of ​​the tape body 110 along the length direction. By providing the cleaning sheet 120, and the cleaning sheet 120 is detachably connected to the tape body 110, the type of the cleaning sheet 120 can be replaced according to actual conditions, thereby expanding the scope of application. Cleaning sheets 120 with different cleaning effects can be selected according to the usage scenario to achieve the target cleaning effect, such as a cleaning sheet made of silicone or a cleaning sheet made of fur.

[0052] Furthermore, when the tape body 110 is wound and moves leftward or rightward, the cleaning sheet 120 sweeps across the viewing window 30 to clean the viewing window 30 .

[0053] Optionally, the tape body 110 is a nylon tape, and the cleaning sheet 120 is detachably connected to the nylon tape via Velcro.

[0054] Optionally, the cleaning sheet 120 is glued to the nylon belt.

[0055] It is understandable that the hollow area 101 and the cleaning sheet 120 matching the window 30 can be designed according to the size of the window 30 .

[0056] Optionally, a light-transmitting member, such as a transparent polyvinyl chloride (PVC) flexible plate, can be provided at the position of the hollow area 101. The light-transmitting member allows light to pass through without affecting the normal shooting of the camera. The strength of the tape body 110 can also be enhanced by providing the light-transmitting member.

[0057] like Figures 1 to 3 As shown, in some embodiments, the cleaning device further includes a housing 600;

[0058] Among them, the housing 600 is arranged on the front side of the window 30, and is used to be detachably connected to the front face 20 to form an installation gap 601; the cleaning tape 100, the pulley 200 and the drive assembly 300 are all arranged in the installation gap 601; the pulley 200 and the drive assembly 300 are detachably connected to the housing 600. By setting the housing 600, it is possible to provide an installation position for the pulley 200 and the drive assembly 300, avoiding the pulley 200 and the drive assembly 300 from being directly installed on the front face 20 of the camera, and also facilitating the overall installation of the cleaning device, thereby improving the installation efficiency. The existing cleaning device cannot be replaced, resulting in the cleaning sheet 120 being severely worn as the use time increases, and the required cleaning effect cannot be achieved. However, this embodiment facilitates the replacement of the cleaning tape 100 by detachably connecting the pulley 200 to the housing 600, thereby ensuring the cleaning effect of the cleaning tape 100 on the window 30. In addition, by providing the housing 600 , the cleaning tape 100 can be located in the installation gap 601 , thereby preventing the cleaning tape 100 from being exposed to the outside, reducing the risk of the cleaning tape 100 being contaminated, and improving the aesthetics.

[0059] It can be understood that the housing 600 is provided with an opening corresponding to the window 30 to allow light to be directed toward the window 30 to avoid blocking the window 30 .

[0060] Specifically, when the cleaning tape 100 cannot meet the cleaning requirements, first remove the outer shell 600 from the front face 20, then remove the pulleys 200 on both sides of the window 30 from the outer shell 600, and replace them with a new cleaning tape 100; finally, reinstall the pulleys 200 wound with the new cleaning tape 100 to the outer shell 600, and then install the outer shell 600 to the front face 20.

[0061] Optionally, the vertical distance between the side of the housing 600 away from the viewing window 30 and the viewing window 30 is 1 mm to 2 mm. This vertical distance can ensure that the blocking of the camera's field of view by the cleaning device is reduced to a sufficiently low level, or even does not block the camera's field of view.

[0062] Specifically, the vertical distance between the side of the housing 600 away from the viewing window 30 and the viewing window 30 is 1 mm, 1.5 mm or 2 mm.

[0063] For ease of description, the following Figures 2 to 4 The pulley 200 on the left side is named as a first pulley 210 , and the pulley 200 on the right side is named as a second pulley 220 .

[0064] In some embodiments, the front face 20 is formed with recessed portions on the left and right sides of the viewing window 30, the first pulley 210 is located in the recessed portion on the left side of the viewing window 30, and the second pulley 220 is located in the recessed portion on the right side of the viewing window 30. By forming the recessed portion on the front face 20, the gap between the cleaning tape 100 and the viewing window 30 can be further reduced, and the height of the cleaning device can be further reduced to avoid blocking the viewing angle of the camera.

[0065] In some embodiments, the driving assembly 300 is connected to the pulleys 200 on both sides to drive the pulleys 200 on both sides to rotate alternately. Specifically, the driving assembly 300 is connected to the first pulley 210 and the second pulley 220. When the driving assembly 300 drives the first pulley 210 to rotate, the second pulley 220 is not driven to rotate, but the second pulley 220 rotates in the same direction as the first pulley 210 under the drive of the cleaning tape 100, so that the cleaning tape 100 moves to the left. When the driving assembly 300 drives the second pulley 220 to rotate, the first pulley 210 is not driven to rotate, but the first pulley 210 rotates in the same direction as the second pulley 220 under the drive of the cleaning tape 100, so that the cleaning tape 100 moves to the right.

[0066] In this embodiment, the cleaning tape 100 can be reused by connecting the drive assembly 300 to the pulleys 200 on both sides.

[0067] Optionally, the driving assembly 300 includes a first driving member 310 and a second driving member 320; the first driving member 310 is connected to the first pulley 210 for driving the first pulley 210 to rotate; the second driving member 320 is connected to the second pulley 220 for driving the second pulley 220 to rotate.

[0068] Optionally, the first driving member 310 includes but is not limited to a stepping motor. The second driving member 320 includes but is not limited to a stepping motor.

[0069] Optionally, one end of the cleaning tape 100 is wound around the first pulley 210, and the other end of the cleaning tape 100 is wound around the second pulley 220; the first driving member 310 is connected to the first pulley 210, and the first driving member 310 drives the first pulley 210 to rotate left, and the first pulley 210 winds up the cleaning tape 100. At the same time, the second pulley 220 rotates left under the drive of the cleaning tape 100 to release the cleaning tape 100, so that the cleaning sheet 120 of the cleaning tape 100 moves from right to left, thereby cleaning the window 30.

[0070] Optionally, one end of the cleaning tape 100 is wound around the first pulley 210, and the other end of the cleaning tape 100 is wound around the second pulley 220; the second driving member 320 is connected to the second pulley 220, and the second driving member 320 drives the second pulley 220 to rotate right, and the second pulley 220 winds up the cleaning tape 100. At the same time, the first pulley 210 rotates right under the drive of the cleaning tape 100 to release the cleaning tape 100, so that the cleaning sheet 120 of the cleaning tape 100 moves from left to right, thereby cleaning the window 30.

[0071] In some embodiments, the cleaning device further includes a pressing assembly 400; the pressing assembly 400 abuts against a side of the cleaning tape 100 away from the window 30, and is used to press the cleaning tape 100 toward the window 30, so that the cleaning tape 100 maintains contact with the window 30. Specifically, the pressing assembly 400 abuts against the front side of the cleaning tape 100, and by providing the pressing assembly 400, the cleaning tape 100 can always maintain contact with the surface of the window 30 during the movement, thereby ensuring the cleaning effect.

[0072] It is understandable that when the pressing assembly 400 presses the cleaning tape 100 toward the viewing window 30 , the cleaning tape 100 can still move to the left or right under the drive of the pulley 200 .

[0073] Optionally, the pressing assembly 400 includes a pressing plate; the pressing plate is provided with an opening corresponding to the viewing window 30 ; the front side of the pressing plate is connected to the housing 600 , and the rear side of the pressing plate abuts against the front side of the cleaning tape 100 .

[0074] Optionally, the pressing assembly 400 includes at least two pressing sheets 410; along the length direction, the two pressing sheets 410 are respectively arranged on both sides of the window 30, and the two pressing sheets 410 are both in contact with the side of the cleaning tape 100 away from the window 30. Specifically, the front side surfaces of the two pressing sheets 410 are connected to the housing 600, the rear side surfaces of the two pressing sheets 410 are in contact with the front side surface of the cleaning tape 100, and the two pressing sheets 410 are respectively arranged on the left and right sides of the window 30 along the length direction. By providing the pressing sheets 410, it is avoided to open holes on the pressing plate, thereby reducing the manufacturing cost, and reducing the material cost.

[0075] In some embodiments, the cleaning device includes a self-cleaning component 500; the self-cleaning component 500 is used to connect with the front face 20, and the self-cleaning component 500 abuts against the side of the cleaning tape 100 facing the window 30, and is used to clean the cleaning tape 100. Specifically, the rear side of the self-cleaning component 500 is used to connect with the front face 20, and the front side of the self-cleaning component 500 abuts against the cleaning sheet 120 on the rear side of the cleaning tape 100. By providing the self-cleaning component 500 to realize automatic cleaning of the cleaning tape 100, the cleaning effect of the cleaning tape 100 on the window 30 can be improved.

[0076] Optionally, the self-cleaning assembly 500 includes a cleaning arm and a driving motor; the driving motor drives the cleaning arm to swing relative to the cleaning tape 100 , thereby achieving automatic cleaning of the cleaning tape 100 .

[0077] Optionally, the self-cleaning assembly 500 includes at least two scrapers 510; along the length direction, the two scrapers 510 are respectively arranged on both sides of the viewing window 30; one end of the scraper 510 is used to be connected to the front face 20, and the other end of the scraper 510 abuts against the side of the cleaning tape 100 facing the viewing window 30. By connecting one end of the scraper 510 to the front face 20, when the cleaning tape 100 moves to the left or right, the cleaning tape 100 also moves relative to the scraper 510, and the other end of the scraper 510 also abuts against the side of the cleaning tape 100 facing the viewing window 30, and the scraper 510 realizes automatic cleaning of the side of the cleaning tape 100 facing the viewing window 30.

[0078] Specifically, the rear side of the scraper blade 510 is connected to the front face 20 , and the front side of the scraper blade 510 abuts against the cleaning sheet 120 . As the cleaning tape 100 moves, the scraper blade 510 moves relative to the cleaning sheet 120 , thereby automatically cleaning the cleaning sheet 120 and improving the cleaning effect of the window 30 .

[0079] like Figure 1 As shown, a specific embodiment of the second aspect of the present invention provides a camera. The camera includes a front face 20, a window 30, and a cleaning device according to any of the above embodiments; the window 30 is embedded in the front face 20, and the cleaning device is located in front of the window 30 and is detachably connected to the front face 20.

[0080] Since the camera of this embodiment includes the cleaning device of any of the above embodiments, it has at least the above advantages.
