Detailed Implementation

[0046] This utility model discloses a cleaning device for cleaning vehicle-mounted cameras. This utility model also provides a vehicle-mounted camera.

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] During the cleaning process of the lens 100 of the vehicle camera, simply rinsing the lens 100 with water (such as using a high-pressure water gun) can leave water stains on the surface of the lens 100 after rinsing, affecting the cleaning effect. Simply wiping the lens 100 can ensure that the dust on the surface of the lens 100 is cleaned, but the wiping parts are prone to getting dirty, which can affect their service life; and, for dirt adhering to the surface of the lens 100 (such as structures formed after the mud and water mixture has dried), simply wiping with the wiping parts can easily affect the cleaning effect.

[0049] Therefore, this utility model embodiment provides a cleaning device that adopts a structure that combines rinsing and wiping.

[0050] like Figures 1-10 As shown in the figure, the cleaning device provided in this embodiment of the present invention is used to clean the lens 100 of a vehicle-mounted camera, and includes a rinsing mechanism 400 and a wiping mechanism. The rinsing mechanism 400 has a water supply path for providing cleaning water to the lens 100; the wiping mechanism includes a wiping component 210 for wiping the lens 100 and a driving component 220 for moving the wiping component 210 relative to the lens 100.

[0051] The cleaning device provided in this embodiment of the utility model includes a rinsing mechanism 400 that supplies cleaning water to the lens 100 through a water supply path to achieve a rinsing operation on the lens 100; and a wiping mechanism whose drive assembly 220 moves the wiping component 210 relative to the lens 100 to achieve a wiping operation on the lens 100. By combining rinsing and wiping, the cleaning operation of the lens 100 can be effectively completed, facilitating the cleaning of vehicle-mounted cameras.

[0052] To facilitate wiping, the wiping component 210 has a wiping rod segment that can be correspondingly arranged with the lens 100 and a connecting rod segment that connects to the end of the wiping rod segment. The wiping rod segment is used to contact and wipe the lens 100; the driving end of the driving assembly 220 is connected to the connecting rod segment. That is, the driving end of the driving assembly 220 and the wiping rod segment are connected by the connecting rod segment, which avoids interference between the driving assembly 220 and the wiping rod segment, and allows for more flexible arrangement of the wiping rod segment, so that the wiping rod segment wipes the lens 100 in a suitable position.

[0053] Of course, the wiping component 210 can also be configured with other structures, such as a "T"-shaped wiping bar, with the connecting rod segment connected to the middle part of the wiping bar segment and the connecting rod segment being perpendicular to the wiping bar segment. Alternatively, the wiping component 210 can be directly configured as a wiping block (such as a sponge or non-woven fabric structure), and the wiping component 210 can be directly connected to the drive end of the drive assembly 220.

[0054] The drive assembly 220 may include a linear drive component and / or a rotary drive component. By activating the drive assembly 220, its drive end moves relative to the main body of the drive assembly 220, thereby driving the wiping component 210 to move relative to the lens 100 to achieve the wiping operation.

[0055] like Figure 3 and Figure 4 As shown, the wiping component 210 has a wiping rod segment that can be correspondingly arranged with the lens 100 and connecting rod segments respectively arranged at both ends of the wiping rod segment. The wiping rod segment is used to contact and wipe the lens 100; the driving end of the driving assembly 220 is connected to the connecting rod segment. With the above arrangement, the wiping component 210 includes a connecting rod segment, a wiping rod segment and a connecting rod segment arranged in sequence. That is, two driving assemblies 220 can be set to be connected to both ends (two connecting rod segments) of the wiping component 210 respectively, so as to achieve the effect of uniformly applying force to the wiping rod segment, ensuring the uniformity of the contact pressure between the wiping rod segment and the lens 100 during the wiping process, thereby improving the wiping effect of the lens 100. Since the driving component 220 can be positioned below the upper surface of the lens 100 (the surface on which the lens 100 acquires image information), a connecting structure can be provided between the wiping rod segment and the connecting rod segment. This allows the wiping rod, including the wiping rod segment and the connecting rod segment, to have an "Ω"-like structure. This allows the lens 100 to be located between the two connecting rod segments, and the wiping rod segment can be moved radially along the lens 100 by the rotation of the connecting rod segment itself (e.g., ...). Figure 8 As shown), the connecting rod segment moves along the circumference of the lens 100 (rotation direction centered on the axis of the lens 100) to realize the operation of rotating the wiping rod segment along the upper surface of the lens 100 (as shown). Figure 7 shrink).

[0056] like Figure 8 As shown, the driving assembly 220 includes a first driving member 221. The driving end of the first driving member 221 is connected to the connecting rod segment and can drive the connecting rod segment to rotate in a first direction, so that the wiping rod segment can move radially along the lens 100. That is, the first driving member 221 is a rotary driving component, and the first direction can be the radial direction of the lens 100. The connecting rod segment rotates along its axis (the axis of rotation of the first driving member 221), thereby driving the wiping rod segment to rotate about the axis of rotation of the first driving member 221 as the axis of rotation, thereby wiping the upper surface of the lens 100. The upper surface of the lens 100 can be a curved surface to improve the wiping effect of the wiping rod segment. Alternatively, the upper surface of the lens 100 can be a flat surface, and the wiping part (such as a sponge or rubber block) of the wiping rod segment can be elastically deformed to fit the upper surface of the lens 100 to complete the wiping operation.

[0057] Furthermore, after wiping, the wiping rod can be moved away from the upper surface of the lens 100 to avoid interference between the wiping component 210 and the lens 100 during image acquisition, thus ensuring the normal use of the lens 100.

[0058] like Figure 7 As shown, the drive assembly 220 includes a second drive member 222, which drives the connecting rod segment to move along a second direction, so that the wiping rod segment can rotate around the center of the lens 100. That is, the second drive member 222 can be a rotary drive component or a linear drive device, and the second direction can be the circumference of the lens 100. The second drive member 222 can drive the connecting rod segment to move along the circumference of the lens 100, so that the wiping rod segment can rotate around the center of the lens 100, thereby wiping the upper surface of the lens 100. The upper surface of the lens 100 can be a curved surface or a flat surface. The wiping operation is completed by the elastic deformation of the wiping part (such as a sponge or rubber block) of the wiping rod segment to conform to the upper surface of the lens 100.

[0059] Preferably, such as Figure 7 and Figure 8 As shown, the drive assembly 220 includes a first drive member 221 and a second drive member 222. The drive end of the first drive member 221 is connected to the connecting rod segment and can drive the connecting rod segment to rotate along a first direction, so that the wiping rod segment can move radially along the lens 100. The second drive member 222 can drive the connecting rod segment to move along a second direction, so that the wiping rod segment can rotate around the center of the lens 100. The first drive member 221 can be a drive member that drives the wiping component 210 to move relative to the lens 100. That is, when wiping is required, the first driving member 221 drives the connecting rod segment of the wiping component 210 to rotate along the first direction, so that the wiping rod segment is correspondingly positioned with the upper surface of the lens 100; when wiping is completed or not required, the first driving member 221 drives the connecting rod segment of the wiping component 210 to rotate along the first direction, so that the wiping rod segment avoids the lens 100 (e.g., the wiping rod segment moves to the side of the lens 100), to avoid interference from the wiping component 210 during image acquisition, ensuring the normal use of the lens 100. The second driving member 222 is the driving member that drives the wiping component 210 to wipe the lens 100. That is, by driving the connecting rod segment to move along the second direction, the wiping rod segment can rotate around the center of the lens 100 as the rotation center to complete the wiping operation on the upper surface of the lens 100.

[0060] That is, through the joint operation of the first driving member 221 and the second driving member 222, two movements can be realized: 360° rotation (the second driving member 222 enables the wiping rod segment to rotate around the center of the lens 100) and reciprocating swing (the first driving member 221 enables the wiping rod segment to move radially along the lens 100), so as to realize the function of wiping the lens 100 from multiple angles.

[0061] like Figure 9 As shown, the drive assembly 220 also includes a slide rail structure 224 and a motion slider 223. The slide rail structure 224 includes an annular track 2241 for being arranged along the outer periphery of the lens 100; the motion slider 223 has a slider portion 2231 that slides in cooperation with the annular track 2241; the second drive member 222 is used to drive the motion slider 223 to move along the annular track 2241; and the main body of the first drive member 221 is connected to the motion slider 223.

[0062] like Figure 5 , Figure 7 and Figure 8 As shown, in the embodiment where connecting rod segments are provided at both ends of the wiping rod segment, the number of moving sliders 223 is also two, and they are arranged one-to-one with the two connecting rod segments. The number of first driving members 221 is two, and they are arranged one-to-one with the two moving sliders 223.

[0063] The main body of the first driving member 221 can be disposed on the motion slider 223, that is, the motion slider 223 carries the first driving member 221.

[0064] Furthermore, the drive assembly 220 also includes a gear 225, which is disposed at the drive end of the second drive member 222; the slide rail structure 224 also includes a gear tooth structure 2242 disposed circumferentially along the annular track 2241, with the gear 225 meshing with the gear tooth structure 2242; the main body of the second drive member 222 is connected to the moving slider 223. Through the above arrangement, the main body of the second drive member 222 can be disposed on the moving slider 223, that is, the moving slider 223 carries the second drive member 222. The second drive member 222 is a rotary drive device.

[0065] Specifically, during the process of the second driving member 222 driving the motion slider 223 to move along the annular track 2241, the driving end of the second driving member 222 drives the gear member 225 to rotate, so that the gear member 225 meshes with the gear tooth structure 2242 and moves circumferentially along the annular track 2241, so that the motion slider 223 moves along the annular track 2241.

[0066] Among them, the gear tooth structure 2242 and the ring track 2241 can be an integral structure or a separate structure, and the two are positioned relative to each other.

[0067] That is, the aforementioned multi-angle lens wiping function of the lens 100 is achieved by two sets of motors (first drive unit 221 and second drive unit 222), a movable wiping rod (wiping rod segment), and a moving slider 223 on the camera support. The second drive unit 222 can be connected to a gear unit 225 located below the moving slider 223 via a rigid coupling. The gear unit 225 meshes with the gear tooth structure 2242 on the camera support. The slider portion 2231 of the moving slider 223 has a groove, which contacts the annular track 2241 on the camera support to ensure the stability of the moving slider 223 during movement.

[0068] The rotors of the two motors (second drive unit 222) rotate in the same direction, driving the gear unit 225 to rotate, thereby enabling the slider to move around the camera in a circular motion, thus allowing the wiping rod (wiping rod segment) to complete a 360° wiping operation on the lens. The rotors of the two motors (first drive unit 221) rotate in opposite directions, driving the wiping rod to rotate, thereby achieving a reciprocating swing wiping of the lens 100.

[0069] Of course, the second driving component 222 can also be set as a linear driving component, and the gear component 225 can be replaced with a rack structure. The rack structure meshes with the gear tooth structure 2242, which can also make the moving slider 223 move along the circular track 2241.

[0070] Alternatively, the drive assembly 220 can include a disk that coincides with the axis of the lens 100. The end of the connecting rod segment away from the wiping rod segment is connected to the disk, and the second drive member 222 is a rotary drive component that drives the disk to rotate, causing the disk to rotate and drive the connecting rod segment to rotate circumferentially around the lens 100, thereby enabling the wiping rod segment to rotate around the center of the lens 100.

[0071] To improve service life, the wiping component 210 includes a wiping rod and a wiping element detachably mounted on the wiping rod. The drive end of the drive assembly 220 is connected to the wiping rod, and the wiping element is used to contact the lens 100. The wiping rod may include the aforementioned wiping rod segment and connecting rod segment, and the wiping element is detachably connected to the wiping rod segment. The wiping element may be a sponge, rubber block, or foam, etc.

[0072] This utility model embodiment also provides a vehicle-mounted camera, including a lens 100, and also includes any of the cleaning devices described above.

[0073] Since the cleaning device described above has the aforementioned technical effects, the vehicle-mounted camera equipped with the cleaning device should also have the same technical effects, which will not be described in detail here.

[0074] like Figure 1 , Figure 2 and Figure 10As shown, the vehicle-mounted camera includes a camera body 200 and a protective cover 300. The lens 100 is located on the first surface 201 of the camera body 200. The protective cover 300 is used to connect with the first surface 201 of the camera body 200. The inner wall of the protective cover 300 and the first surface 201 of the camera body 200 form a receiving cavity for accommodating the lens 100. The protective cover 300 has a window for light to pass through and is correspondingly arranged with the lens 100. The wiping mechanism of the cleaning device is located in the receiving cavity.

[0075] That is, the protective cover 300 has the function of protecting the lens 100 and the wiping mechanism, and the protective cover 300 can also play a certain role in dust and water protection. In actual use, the protective cover 300 will be embedded in the whole vehicle of the vehicle on which the vehicle-mounted camera is installed.

[0076] like Figure 1 and Figure 6 As shown, the flushing mechanism 400 includes an outer pipe 410 and an inner pipe 420 that are interconnected. The water supply path includes the pipes of the outer pipe 410 and the inner pipe 420. The outer pipe 410 is located outside the receiving cavity and is used to connect to an external water supply device. The inner pipe 420 is located inside the receiving cavity, and its water outlet can be correspondingly set with the lens 100. The flushing mechanism 400 can be a high-pressure flushing pipe to clean the lens. The external water supply device connected to the outer pipe 410 can include an external water tank. A high-pressure pump draws water from the water tank and introduces the water into the outer pipe 410, which then flows into the inner pipe 420. Since the inner pipe 420 passes through the outer wall of the protective cover 300 around the lens 100, the flushing function can be realized. To avoid interference between the inner tube 420 and the wiping component 210, the inner tube 420 can be configured as a flexible tube (such as a rubber tube). When the inner tube 420 is in contact with the wiping component 210, the inner tube 420 can avoid the wiping component 210 through elastic deformation. Alternatively, the inner tube 420 can be moved relative to the lens 100. During the rinsing operation, the inner tube 420 moves to a position corresponding to the lens 100 so that the liquid flowing out of the inner tube 420 can rinse at least the upper surface of the lens 100. When rinsing is complete or not required, the inner tube 420 moves away from the lens 100 to avoid interference between the inner tube 420 and the wiping component 210.

[0077] Furthermore, the shield 300 has a drainage function for clean water.

[0078] The protective cover 300 may have a water outlet on the first surface 201 near the camera body 200 for the liquid inside the cavity to flow out. That is, the water outlet at the bottom of the protective cover 300 allows more water to flow out from the water outlet, thus relieving the water pressure.

[0079] Furthermore, the first surface 201 of the camera body 200 may have an annular groove 202 located outside the lens 100 and an inclined groove 203 connecting the annular groove 202 and the outer wall of the camera body 200, the inclined groove 203 being inclined downward in a direction away from the lens 100. Preferably, the camera support (first surface 201) has an annular groove 202, and four or six inclined grooves 203 with slopes are evenly distributed around the annular groove 202, which can completely drain residual cleaning water.

[0080] The cleaning device provided in this embodiment is applied to a vehicle-mounted camera. The working principle of the vehicle-mounted camera in a vehicle is as follows:

[0081] While the car is in motion, the controller automatically analyzes the images captured by the onboard camera to determine if there is any dirt or grime. If dirt is found, a message will appear on the dashboard or center console indicating that the lens is dirty and the driver needs to activate the onboard camera cleaning function.

[0082] When the vehicle camera cleaning function is turned on, the water spraying mechanism 400 (high-pressure water pipe) will spray water to clean the upper surface of the lens 100, initially removing dust from the upper surface of the lens 100.

[0083] Then, a pair of motors (first drive unit 221) rotate in opposite directions to realize the reciprocating swing of the movable wiping rod, thereby performing a preliminary wipe on the upper surface of the lens 100; then, a pair of motors (second drive unit 222) rotate in the same direction to drive two gears to rotate in the same direction, thereby causing the two moving sliders 223 to slide along the circular track 2241, realizing the 360° rotation of the movable wiping rod, thereby performing a detailed wipe on the upper surface of the lens 100, and finally completing the cleaning of the lens.

[0084] In addition, the cleaning device is equipped with a drainage function. The water outlet on the cover 300 can drain the cleaning water in time. The multiple inclined grooves 203 evenly distributed on the bottom (first surface 201) of the cover 300 can help drain the residual water inside gradually.

[0085] The vehicle-mounted camera provided in this embodiment can effectively clean dirt and water stains from the lens 100 of the vehicle-mounted camera during vehicle operation, thus meeting the cleaning needs of the lens 100.

[0086] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0087] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention.
