Description

Technical Field

[0001] The utility model relates to the technical field of camera sensor lens cleaning, in particular to a cleaning device. Background Art

[0002] Camera sensors have increasingly strict requirements for lens cleanliness, especially when used outdoors or in harsh environments. Water, fog, frost, mud, insects and other substances may adhere to the surface, blocking the camera sensor's sensing area and causing image blur, distortion, glare, etc. If this type of camera sensor is used in autonomous driving, it will cause safety accidents.

[0003] Currently, most camera sensors on the market lack lens cleaning devices. A small number of camera sensors incorporate a water-spraying nozzle within the lens's sensing area. This nozzle sprays a large amount of cleaning fluid onto the lens surface during the cleaning process, resulting in continuous obstruction of the sensor's sensing area and causing the sensor to malfunction. Furthermore, after cleaning, a significant amount of cleaning fluid remains on the lens surface, obstructing the sensor's sensing area and attracting dust from the environment, resulting in secondary contamination. To address this residual cleaning fluid issue, existing technologies have improved the nozzle assembly by replacing the original nozzle assembly with a raised jet nozzle assembly that features both water and air jet functions. This assembly operates by performing an air jet after spraying the cleaning fluid to remove residual cleaning fluid. However, this raised jet nozzle assembly is relatively complex in structure, and to address the residual cleaning fluid issue, a large number of nozzles are typically required. Consequently, when used in mining areas, the raised jet nozzle assembly is susceptible to damage from scratches or bumps.

[0004] To this end, the utility model provides a cleaning device. Utility Model Content

DETAILED DESCRIPTION

[0029] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and are not to be construed as limitations on the present application. In addition, the following embodiments and features in the embodiments may be combined with each other unless there is a conflict. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0031] like Figures 1-10 As shown, a cleaning device includes: a base 1, a cover plate 2 and a valve body 3, wherein a first guide unit for placing a camera sensor lens 6 to be cleaned is provided at the front end of the base 1, a first fluid output unit for conveying pressurized gas and / or pressurized liquid to the first guide unit is provided in the base 1, and a second fluid output unit connected to the first fluid output unit is provided in the base 1. By providing the base 1, the cover plate 2, the valve body 3, the first guide unit, the second guide unit, the first fluid output unit and the second fluid output unit, the device can realize multiple cleaning modes, is suitable for multiple lens cleaning needs, and makes lens cleaning more efficient and convenient.

[0032] It should be noted that the present application can use different cleaning modes according to different cleaning needs to clean different types of dirt, making cleaning more efficient and faster. For example, when cleaning water droplets on the surface of the camera sensor lens 6, pressurized gas can be applied and the airflow of the pressurized gas can be used to clean the lens surface. That is, in this mode, if liquid substances are attached to the surface of the camera sensor lens 6, only pressurized gas needs to be introduced for cleaning without consuming cleaning liquid, so as to reduce the consumption of cleaning liquid; for example, when cleaning mud on the surface of the camera sensor lens 6, pressurized liquid can be introduced first, and then pressurized gas can be introduced to form a water mist spray, and the water mist can be used to flush the mud on the lens surface. Pressurized gas can then be introduced multiple times to clean the residual liquid on the lens surface by a separate jet to complete the lens cleaning operation. That is, in this mode, if solid dirt such as dust, mud, and insect corpses are attached to the surface of the camera sensor lens 6, the atomized cleaning liquid can be used to clean the lens surface and flushed with the airflow of pressurized gas. Compared with the existing nozzle device with a water spray function, the consumption of cleaning liquid can be effectively reduced.

[0033] In one possible implementation, Figure 2 As shown, the first guide unit is a guide surface 8, and a lens placement hole 10 is provided on the guide surface 8 at a position corresponding to the camera sensor lens 6 to be cleaned. It should be noted that, in this embodiment, the guide surface 8 is preferably a smooth plane to facilitate improving the cleaning effect. At the same time, a lens placement hole 10 is provided on the guide surface 8 for placing the camera sensor lens 6 to be cleaned; in addition, by adding a guide surface 8 on the outside of the camera sensor lens 6, and designing the injection port 19 of the guide groove 18 into a planar structure, both have high structural strength and can protect the camera sensor lens 6. Especially when the camera sensor 21 is used on a special vehicle in a mining area and there is a lot of sand and gravel splashing in the mining area, it can not only ensure the damage resistance of the injection nozzle itself, but also reduce the probability of sand and gravel impacting and damaging the camera sensor 21.

[0034] In one possible embodiment, the first fluid output unit is a first fluid output channel 4, and a through hole 9 is provided on the guide surface 8 at a position corresponding to the first fluid output channel 4. It should be noted that, in this embodiment, one end of the first fluid output channel 4 can be connected to the pressure gas storage device, and the other end is connected to the second guide unit through the through hole 9, so as to transport the pressure gas through the first fluid output channel 4 to the second guide unit, and apply the pressure gas to the surface of the camera sensor lens 6 to be cleaned via the second guide unit.

[0035] In one possible implementation, Figure 3As shown, the cover plate 2 and the first guide unit are clearance-fitted to form a second guide unit, and the second guide unit is communicated with the first fluid output unit for applying the pressurized gas and / or pressurized liquid passing through the first fluid output unit to the surface of the camera sensor lens 6 to be cleaned. The second fluid output unit is a second fluid output channel 5, one end of the second fluid output channel 5 passes through the base 1 and is detachably connected to the valve body 3, and the other end of the second fluid output channel 5 is communicated with the first fluid output channel 4. It should be noted that by setting the second fluid output channel 5 and the valve body 3, the valve body 3 can be used to transport the pressurized liquid through the second fluid output channel 5 to the first fluid output channel 4, and then transport it to the second guide unit via the first fluid output channel 4, and finally apply the pressurized liquid to the surface of the camera sensor lens 6 to be cleaned via the second guide unit.

[0036] In one possible embodiment, the valve body 3 includes a valve seat 13, and a third fluid output unit for conveying the pressurized liquid to the second fluid output channel 5 is provided in the valve seat 13. The third fluid output unit is connected to the second fluid output channel 5. The valve seat 13 is provided with a check member for preventing the pressurized liquid or pressurized gas from flowing back, and the check member is arranged at the connection between the third fluid output unit and the second fluid output channel 5. It should be noted that in this embodiment, the valve body 3 has two structural compositions. The valve body 3 can be composed of a valve seat 13 and a rubber sleeve 14, or it can be composed of a valve seat 13 and a check valve. It can be flexibly selected according to actual conditions. As long as it can realize the conveyance of pressurized liquid to the second fluid output channel 5 and prevent the pressurized liquid or pressurized gas from flowing back into the valve seat 13, it will not be limited here.

[0037] In one possible implementation, Figure 3 and Figure 7As shown, when the valve body 3 is composed of a valve seat 13 and a rubber sleeve 14, a cylindrical sealing end face 15 is provided at one end of the valve seat 13, and a third fluid output channel 16 is provided in the valve seat 13. A fourth fluid output channel 17 connected to the third fluid output channel 16 is opened on the cylindrical sealing end face 15. The fourth fluid output channel 17 is connected to the second fluid output channel 5. The third fluid output channel 16 is used to transport the pressurized liquid to the second fluid output channel 5 through the fourth fluid output channel 17. The rubber sleeve 14 is sleeved on the cylindrical sealing end face 15 to prevent the pressurized liquid or pressurized gas from generating backflow in the second fluid output channel 5, and the rubber sleeve 14 covers the fourth fluid output channel 17. It should be noted that In this embodiment, when the pressure liquid flows to the fourth fluid output channel 17 through the third fluid output channel 16, the pressure of the pressure liquid can push open the rubber sleeve 14 covering the fourth fluid output channel 17, and then enter the second fluid output channel 5, and then be transported to the second guide unit by the first fluid output channel 4, and finally the pressure liquid is applied to the surface of the camera sensor lens 6 to be cleaned through the second guide unit. In addition, the elastic effect of the rubber sleeve 14 can be used to tighten it on the cylindrical sealing end face 15 of the valve seat 13, playing a check function; at the same time, an external thread section is provided on the valve seat 13, and a corresponding internal thread section is provided at the position of the second fluid output channel 5 corresponding to the external thread section, which is convenient for assembly.

[0038] In one possible embodiment, when the valve body 3 is composed of a valve seat 13 and a check member, a fifth fluid output channel 26 for conveying pressurized liquid to the second fluid output channel 5 is provided in the valve seat 13, and the third fluid output unit is connected to the second fluid output channel 5. A check member is provided at the front end of the valve seat 13 for preventing the pressurized liquid or pressurized gas from flowing back, and the check member is arranged at the connection between the fifth fluid output channel 26 and the second fluid output channel 5. The working principle of the valve body composed of the valve seat 13 and the check member is similar to that of the check valve. Therefore, the types of such valve bodies include but are not limited to spring-type check valves, ball-type check valves, wave check valves, piston-type check valves, etc., which can be flexibly selected according to actual conditions. As long as it can prevent the pressurized liquid or pressurized gas from flowing back into the valve seat 13, it is no longer limited here. At the same time, in this embodiment, two types of valve bodies are provided, including a spring-type check valve (such as Figure 8 as shown) and ball check valves (as Figure 9As shown), the spring-loaded check valve is composed of a valve seat 13, a first compression spring 22 and a valve disc 23. One end of the first compression spring 22 is fixedly connected to the inner wall of the second fluid output channel 5, and the other end is fixedly connected to the valve disc 23 to push the valve disc 23 to close. Its working principle is as follows: under pressure gas and / or pressure liquid or in a non-working state, the first compression spring 22 is in a compressed state, and the valve disc 23 can be closed under the action of the first compression spring 22 to achieve unidirectional flow of the fluid. When it is necessary to introduce pressure liquid into the second fluid output channel 5, the first compression spring 22 is in a compressed state under the action of the pressure liquid. 2 is compressed, and the pressurized liquid pushes open the valve disc 23 and enters the second fluid output channel 5, thereby achieving the function of passing the pressurized liquid. The ball check valve consists of a valve seat 13, a second compression spring 24 and a ball valve 25. One end of the first compression spring 24 is fixedly connected to the inner wall of the second fluid output channel 5, and the other end is fixedly connected to the ball valve 25, which is used to push the ball valve 25 to close. Its working principle is similar to that of the spring-type check valve and will not be described in detail here. In addition, an external threaded section is provided on the valve seat 13, and a corresponding internal threaded section is provided at the position corresponding to the external threaded section in the second fluid output channel 5 to facilitate assembly.

[0039] In one possible implementation, Figure 6 As shown, the second guide unit is a guide groove 18, the through hole 9 is provided in the guide groove 18, the guide groove 18 is a fan-shaped opening structure, the open end of the guide groove 18 is a jet port 19, and the jet port 19 is a planar structure. It should be noted that, in this embodiment, the pressure liquid and / or pressure gas enters the guide groove 18 through the first fluid output channel 4, flows out from the jet port 19 at the end of the guide groove 18, flushes the lens surface, and completes the cleaning operation; in addition, compared with the existing convex jet nozzle device, for example: the jet port 19 is a circular hole-shaped nozzle, and the jet port of the guide groove 18 of the present application is 19 is a surface structure. Since the divergent surface of the guide groove 18 is a conical area starting from the injection port 19, if it is necessary to cover the same area of the lens at the same cone angle, the existing nozzle needs to be arranged at a position far away from the lens, which is not convenient for spatial arrangement and occupies more space. At the same time, the distance between the nozzle and the lens is far, which will cause the pressure liquid and / or pressure gas ejected from the nozzle to have more energy flow loss and poor energy efficiency. The injection port 19 with a surface structure can effectively shorten the arrangement distance between the guide groove 18 and the lens, effectively reduce energy flow loss, and improve energy efficiency.

[0040] In a possible embodiment, the cover plate 2 is detachably connected to the first guide unit by opening a threaded through hole on the cover plate 2 and a corresponding threaded mounting hole on the guide surface 8. The two can be assembled using screws for easy assembly and disassembly.

[0041] In one possible embodiment, a sealing unit for sealing the guide groove 18 is provided between the cover plate 2 and the guide surface 8. It should be noted that, in this embodiment, the sealing unit has two structural compositions. The sealing unit can be composed of a sealing groove 20 and a sealing body, or it can be a sealing gasket 12. It can be flexibly selected according to actual conditions. As long as the function of sealing the guide groove 18 can be achieved, it will not be limited here.

[0042] In one possible implementation, Figure 3-Figure 4 As shown, the sealing unit includes a sealing groove 20 and a sealing body. The sealing groove 20 is arranged on the cover plate 2, and the inner contour of the sealing groove 20 is arranged to fit the outer contour of the guide groove 18. The sealing body is arranged in the sealing groove 20. By arranging the sealing groove 20 on the outside of the guide groove 18 and filling the sealing body in the sealing groove 20, the guide groove 18 can be sealed. It should be noted that the sealing body can be sealed with a sealing strip or filled with sealant.

[0043] In one possible implementation, Figure 10 As shown, the sealing unit is a sealing gasket 12, which is provided with a notch. The inner contour of the notch is the same as the outer contour of the guide groove 18, and a through hole is opened on the sealing gasket 12 to facilitate the assembly of the cover plate 2, the sealing gasket 12 and the guide surface 8.

[0044] In one possible embodiment, a clamping unit for fixing the camera sensor 21 to be cleaned is provided on the side of the base 1, and the clamping unit includes a first clamping arm 7 and a second clamping arm. The first clamping arm 7 and the second clamping arm are arranged on both sides of the base 1, and the first clamping arm 7 and the second clamping arm are provided with a plurality of threaded holes 11 for threaded connection of fastening screws; by providing the first clamping arm 7 and the second clamping arm, the camera sensor 21 can be installed between the two, and there are at least two groups of threaded holes 11 on the first clamping arm 7 or the second clamping arm, which can quickly adapt to camera sensors 2 of various sizes. 1, so as to quickly adjust the installation position of the camera sensor 21 in the upper, lower, left, right, front and rear directions, and keep the camera sensor lens 6 aligned and flat with the first guide unit. No additional adapter is required, and the device can be firmly installed on the camera sensor 21. Even in a relatively harsh vibration and impact environment, the cleaning effect of the device can be guaranteed. It should be noted that, in this embodiment, the first clamping arm 7 and the second clamping arm are preferably arranged symmetrically. During the clamping process, it can ensure that the two sides of the camera sensor 21 are evenly stressed, and it is not easy to deviate during the assembly process, which is convenient for installation.

[0045] The working principle of the present invention is as follows: first, a sealing unit is installed between the cover plate 2 and the guide surface 8, and the sealing unit is flexibly selected according to actual conditions. Then, the cover plate 2 is fixed to the base 1 with screws, and then the valve body is threadedly connected to the second channel 5. The device is then integrated with the camera sensor by screws, and the valve body 3 is connected to the external pressure liquid storage device, and the external pressure gas storage device is connected. Different cleaning modes are used according to the cleaning requirements of the camera sensor lens 6 surface. For example: when cleaning water droplets on the surface of the camera sensor lens 6, pressurized gas can be applied and the airflow of pressurized gas can be used to clean the lens surface. For example: when cleaning mud and dirt on the surface of the camera sensor lens 6, pressurized liquid can be introduced first, and then pressurized gas can be introduced to form a water mist spray, and the water mist can be used to flush the mud and dirt on the lens surface. Pressurized gas can be introduced multiple times, and the residual liquid on the lens surface can be cleaned by a separate jet to complete the lens cleaning operation.
