Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a cleaning device and a vehicle having the same. Background Technology

[0002] With the development of vehicle technology, the level of vehicle intelligence is also increasing. In order to realize various intelligent functions of vehicles, more and more sensors are installed on vehicles. During the operation of the vehicle, when the sensors are blocked by debris, it may affect the normal operation of the sensors. Therefore, some models are equipped with sensors cleaning devices. In related technologies, the cleaning position of the cleaning medium and the position of the sensor are prone to deviation, which affects the cleaning effect on the sensors. Utility Model Content

[0003] This application provides a cleaning device and a vehicle having the same, aiming to improve the problem of poor cleaning effect of the cleaning device on sensor assemblies.

[0004] A cleaning apparatus according to a first aspect of this application includes: a housing adapted to be connected to a vehicle body; a sensor assembly disposed on the housing; a controller and a limit switch disposed on the housing and electrically connected to the controller; and a cleaning assembly including a flap and a first drive member, the flap being rotatably connected to the housing, the first drive member being electrically connected to the controller, the flap having a nozzle communicating with a cleaning medium container, the nozzle being adapted to spray a cleaning medium, the first drive member being adapted to drive the flap to a cleaning position, in which the nozzle is positioned toward the sensor assembly, and the flap triggering the limit switch.

[0005] According to the cleaning apparatus of the first aspect of this application, the sensor assembly can be cleaned, and by setting a limit switch, the positional accuracy of the nozzle when the cleaning apparatus cleans the sensor assembly can be improved, so that the cleaning medium can more accurately rinse the sensor assembly and improve the cleaning effect of the cleaning apparatus on the sensor assembly.

[0006] According to some embodiments of this application, a through hole is formed on the housing along the thickness direction, the through hole is spaced apart from the sensor assembly in a first direction, one end of the flap extends into the through hole and is rotatably connected to the inner wall of the through hole, the nozzle is spaced apart from the rotation axis of the flap, the extension direction of the rotation axis of the flap is perpendicular to the thickness direction of the flap, and the first direction is perpendicular to the extension direction of the rotation axis of the flap.

[0007] By setting through holes and making the flap rotatably connected to the inner wall of the through holes, the component structure of the cleaning device can be made more compact, reducing the space occupied by the cleaning device on the vehicle, and thus reducing the difficulty of arranging the cleaning device on the vehicle.

[0008] According to some embodiments of this application, the cleaning assembly further includes: a push rod connected between the flap and the first driving member, one end of the push rod being rotatably connected to the flap, and the first driving member being adapted to drive the push rod to move along the length direction of the push rod so as to drive the flap to rotate.

[0009] The flap is rotated by pushing the push rod. When the flap stops, the torque of the flap on the push rod is small, so that the flap and push rod can stop moving more smoothly, reducing the displacement of the flap and push rod when they stop moving, and further improving the positional accuracy of the nozzle.

[0010] According to some embodiments of this application, the limit switch is disposed on the side edge of the through hole away from the sensor assembly in the first direction. The limit switch has a trigger part opposite to the through hole. In the direction of the nozzle toward the rotation axis of the flap, one end of the flap is provided with a sealing plate. The sealing plate and the nozzle are respectively disposed on both sides of the rotation axis of the flap. The flap also has a storage position. In the storage position, the flap and the sealing plate are disposed in the through hole. The sealing plate and the trigger part are arranged at intervals. In the cleaning position, the sealing plate contacts the limit switch to trigger the limit switch.

[0011] Therefore, the limit switch can be triggered when the flap is in the cleaning position, and the triggering structure is relatively simple, which can reduce the difficulty of production and design.

[0012] According to some embodiments of this application, in the storage location, the flap and the sealing plate block the through hole.

[0013] This reduces the probability of foreign objects interfering with other components by passing through the through-hole, thus improving the reliability of the vehicle during operation.

[0014] According to some embodiments of this application, in the storage position, a fixing hole is formed on the side surface of the flap facing the trigger part, and the nozzle is disposed in the fixing hole. The cleaning device further includes a baffle, the thickness of which is less than the thickness of the housing at the through hole, the baffle is disposed in the through hole, and the baffle is connected to the inner wall of the through hole near the sensor assembly. In the storage position, the flap and the baffle are stacked. In the cleaning position, in the direction of the sensor assembly facing the through hole, the baffle extends beyond the nozzle.

[0015] By setting up a baffle, when the nozzle sprays the cleaning medium toward the sensor assembly, the baffle can block the cleaning medium, reducing the probability of the cleaning medium entering the through hole and the probability of the cleaning medium passing through the through hole affecting the normal operation of other components. This can further improve the reliability of the vehicle during operation.

[0016] According to some embodiments of this application, the cleaning assembly further includes: a cleaning pipeline and a second driving member, the cleaning pipeline being connected between the nozzle and the cleaning medium container, the second driving member being connected in series on the cleaning pipeline, the second driving member being electrically connected to the controller, and the second driving member being adapted to drive the cleaning medium to be ejected from the nozzle.

[0017] This allows for the linkage between the nozzle and the flap position, reducing the probability of the nozzle accidentally spraying when the flap has not reached the cleaning position. Furthermore, the flap rotation into position serves as the trigger condition for the nozzle to work, which can improve the cleaning efficiency of the cleaning device.

[0018] According to some embodiments of this application, a cleaning channel is formed inside the flap, and the cleaning pipeline passes through the cleaning channel and is connected to the nozzle.

[0019] Therefore, the space occupied by the cleaning pipeline and the flap can overlap, making the component structure of the cleaning device more compact, thereby further reducing the difficulty of the layout and design of the cleaning device.

[0020] According to some embodiments of this application, the housing is further provided with a mounting hole extending through the housing in the thickness direction. The sensor assembly includes a radar and a protective housing. The protective housing is sealed in the mounting hole. The radar is connected to the side of the protective housing facing the vehicle body. The protective housing is formed as a viewing window for the radar. In the cleaning position, the nozzle is positioned facing the mounting hole, and the nozzle and the radar are respectively located on both sides of the protective housing in the thickness direction of the housing.

[0021] By installing a protective shell, the radar can be protected. By sealing the mounting hole with the protective shell, the radar can transmit and receive signals normally. Furthermore, by placing the radar between the protective shell and the vehicle body, the probability of damage to the radar during operation can be reduced.

[0022] The vehicle according to the second aspect of this application includes: the cleaning device according to the first aspect of this application; and a vehicle body, wherein the housing is connected to the vehicle body.

[0023] According to the second aspect of this application, by providing the cleaning device according to the first aspect of this application, the cleaning effect on the sensor assembly can be improved, thereby reducing the probability of sensor assembly failure during operation and improving the reliability of the vehicle during operation.

[0034] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] The following is for reference. Figure 1 The cleaning apparatus 100 according to an embodiment of this application is described.

[0036] The cleaning device 100 provided in this application embodiment, such as Figure 1 As shown, it includes: housing 10, sensor assembly 20, controller, limit switch 30 and cleaning assembly 40.

[0037] Specifically, the housing 10 is adapted to be connected to the vehicle body, the sensor assembly 20 is disposed on the housing 10, the limit switch 30 is disposed on the housing 10 and is electrically connected to the controller, the cleaning assembly 40 includes a flap 41 and a first drive member 42, the flap 41 is rotatably connected to the housing 10, the first drive member 42 is electrically connected to the controller, the flap 41 is provided with a nozzle 411, the nozzle 411 is in communication with the cleaning medium container, the nozzle 411 is adapted to spray the cleaning medium, the first drive member 42 is adapted to drive the flap 41 to rotate to the cleaning position, in the cleaning position, the nozzle 411 is positioned toward the sensor assembly 20, and the flap 41 triggers the limit switch 30.

[0038] The sensor assembly 20 can be either a radar assembly 21 or a camera assembly.

[0039] During vehicle operation, when the sensor assembly 20 needs to be cleaned, the first drive unit 42 drives the flap 41 to rotate toward the cleaning position. When the flap 41 triggers the limit switch 30, the limit switch 30 transmits an electrical signal to the controller. The controller controls the first drive unit 42 to stop driving the flap 41 and fix the position of the flap 41 at the cleaning position according to the electrical signal transmitted by the limit switch 30. Then, the nozzle 411 sprays cleaning medium toward the sensor assembly 20. The cleaning medium washes away the debris on the sensor assembly 20, thereby cleaning the sensor assembly 20.

[0040] Understandably, compared to the controller controlling the stroke of the first drive unit 42 to control the position of the flap 41, by setting the limit switch 30, when the flap 41 reaches the cleaning position, the actual position of the flap 41 coincides more closely with the theoretically designed cleaning position. Thus, when the nozzle 411 sprays the cleaning medium toward the sensor assembly 20, the actual coverage of the cleaning medium on the sensor assembly 20 coincides more closely with the theoretical coverage of the cleaning medium, and the cleaning medium can more accurately rinse the sensor assembly 20.

[0041] According to the cleaning device 100 provided in the embodiments of this application, the sensor assembly 20 can be cleaned. Furthermore, by setting the limit switch 30, the positional accuracy of the nozzle 411 when the cleaning device cleans the sensor assembly 20 can be improved, thereby allowing the cleaning medium to more accurately rinse the sensor assembly 20 and improving the cleaning effect of the cleaning device 100 on the sensor assembly 20.

[0042] In some embodiments of this application, such as Figure 1 As shown, a through hole 11 is formed on the housing 10 along the thickness direction. The through hole 11 and the sensor assembly 20 are arranged at intervals in the first direction. One end of the flap 41 extends into the through hole 11 and is rotatably connected to the inner wall of the through hole 11. The nozzle 411 is arranged at intervals with the rotation axis of the flap 41. The extension direction of the rotation axis of the flap 41 is perpendicular to the thickness direction of the flap 41. The first direction is perpendicular to the extension direction of the rotation axis of the flap 41.

[0043] In this way, during the rotation of the flap 41, the through hole 11 can provide clearance space for the flap 41. When the flap 41 is retracted, the through hole 11 can accommodate at least part of the flap 41. As a result, the space occupied by the flap 41 and the housing 10 will overlap to a certain extent, which can make the component structure of the cleaning device 100 more compact, reduce the space occupied by the cleaning device 100 in the vehicle, and thus reduce the difficulty of arranging the cleaning device 100 in the vehicle.

[0044] In some embodiments of this application, such as Figure 1 As shown, the cleaning assembly 40 further includes a push rod 43, which is connected between the flap 41 and the first driving member 42. One end of the push rod 43 is rotatably connected to the flap 41. The first driving member 42 is adapted to drive the push rod 43 to move along the length of the push rod 43 so as to drive the flap 41 to rotate.

[0045] For example, the first driving member 42 can be a linear motor, and the push rod 43 is connected to the motor shaft of the linear motor so that the first driving member 42 drives the push rod 43 to move along the length direction of the push rod 43; the first driving member 42 can also be a rotary motor, and the push rod 43 is connected to the motor shaft of the first driving member 42 through a ball screw transmission mechanism so that the first driving member 42 drives the push rod 43 to move along the length direction of the push rod 43; the first driving member 42 is fixed to the vehicle body.

[0046] Understandably, compared to rotary transmission, the torque exerted by the push rod 43 on the push rod 43 when the flap 41 stops is smaller when the flap 41 rotates. Thus, when the flap 41 triggers the limit switch 30 to stop the first drive member 42 from driving the push rod 43, the impact of the push rod 43 on the first drive member 42 is smaller. This allows the flap 41 and the push rod 43 to stop moving more smoothly, reducing the displacement of the flap 41 and the push rod 43 when they stop moving, and further improving the positional accuracy of the nozzle 411.

[0047] In some embodiments of this application, such as Figure 1 As shown, the limit switch 30 is located on the side edge of the through hole 11 away from the sensor assembly 20 in the first direction. The limit switch 30 has a trigger part 31, which is opposite to the through hole 11. In the direction of the nozzle 411 toward the rotation axis of the flap 41, a sealing plate 412 is provided at one end of the flap 41. The sealing plate 412 and the nozzle 411 are respectively located on both sides of the rotation axis of the flap 41. The flap 41 also has a storage position. In the storage position, the flap 41 and the sealing plate 412 are located in the through hole 11. The sealing plate 412 and the trigger part 31 are arranged at intervals. In the cleaning position, the sealing plate 412 contacts the limit switch 30 to trigger the limit switch 30.

[0048] For example, the first drive member 42 and the flap 41 are respectively disposed on both sides of the limit switch 30. The first drive member 42 is fixed to the vehicle body, and the push rod 43 passes through the through hole 11 to push the flap 41 to rotate.

[0049] When the sensor assembly 20 needs to be cleaned, the first drive member 42 drives the push rod 43 to push the flap 41 so that the nozzle 411 gradually moves away from the housing 10 and rotates. At the same time, the sealing plate 412 gradually rotates toward the trigger part 31. When the sealing plate 412 contacts the trigger part 31 and triggers the limit switch 30, the flap 41 reaches the cleaning position. The controller controls the first drive member 42 to stop driving the push rod 43 and fix the flap 41 in the cleaning position. After cleaning is completed, the first drive member 42 drives the push rod 43 to move in the opposite direction of the above process. The push rod 43 drives the flap 41 to gradually rotate to the storage position.

[0050] Therefore, the limit switch 30 can be triggered when the flap 41 is in the cleaning position. The triggering structure is relatively simple, which can reduce the difficulty of production and design. In addition, when the flap 41 is stored, the sealing plate 412 can block the space between the flap 41 and the inner wall of the through hole 11, reduce the probability of foreign objects passing through the through hole 11, and improve the reliability of the vehicle during operation.

[0051] In some embodiments of this application, at the storage location, the flap 41 and the sealing plate 412 block the through hole 11.

[0052] For example, in the storage position, a sealing material is filled between the flap 41 and the inner wall of the through hole 11, and a sealing material is filled between the sealing plate 412 and the inner wall of the through hole 11.

[0053] This further reduces the probability of foreign objects interfering with other components by passing through the through hole 11, thereby improving the reliability of the vehicle during operation.

[0054] In some embodiments of this application, such as Figure 1 As shown, a fixing hole 413 is formed on the side surface of the flap 41 facing the trigger part 31 in the storage position, and the nozzle 411 is disposed in the fixing hole 413. The cleaning device 100 also includes a baffle 50. The thickness of the baffle 50 is less than the thickness of the housing 10 at the through hole 11. The baffle 50 is disposed in the through hole 11 and is connected to the inner wall of the through hole 11 near the sensor assembly 20. In the storage position, the flap 41 and the baffle 50 are stacked. In the cleaning position, in the direction of the sensor assembly 20 facing the through hole 11, the baffle 50 extends beyond the nozzle 411.

[0055] When the sensor assembly 20 needs to be cleaned, the first driving member 42 drives the flap 41 to gradually rotate to the cleaning position. During this process, the nozzle 411 gradually moves away from the baffle 50. After cleaning, the first driving member 42 drives the flap 41 to rotate from the cleaning position to the storage position. During this process, the nozzle 411 gradually approaches the baffle 50. In the storage position, the flap 41 and the baffle 50 are stacked, and the baffle 50 covers the nozzle 411.

[0056] By setting the baffle 50, when the nozzle 411 sprays the cleaning medium toward the sensor assembly 20, the baffle 50 can block the cleaning medium, reducing the probability of the cleaning medium entering the through hole 11 and the probability of the cleaning medium passing through the through hole 11 and affecting the normal operation of other components. Thus, the reliability of the vehicle during operation can be further improved.

[0057] In some embodiments of this application, such as Figure 1 As shown, the cleaning assembly 40 also includes a cleaning pipeline 60 and a second drive unit 70. The cleaning pipeline 60 is connected between the nozzle 411 and the cleaning medium container. The second drive unit 70 is connected in series with the cleaning pipeline 60 and is electrically connected to the controller. The second drive unit 70 is adapted to drive the cleaning medium to be sprayed out from the nozzle 411.

[0058] When the sensor assembly 20 needs to be rinsed, the first drive unit 42 drives the flap 41 to rotate to the cleaning position. When the flap 41 reaches the cleaning position, the flap 41 triggers the limit switch 30. The limit switch 30 sends an electrical signal to the controller. The controller controls the first drive unit 42 to stop driving the flap 41, and the controller controls the second drive unit 70 to enter the working state, so that the nozzle 411 sprays the cleaning medium toward the sensor assembly 20.

[0059] Therefore, the position states of the nozzle 411 and the flap 41 can be linked, reducing the probability of the nozzle 411 spraying accidentally when the flap 41 has not reached the cleaning position. Furthermore, the rotation of the flap 41 into position serves as the condition for triggering the operation of the nozzle 411, which can improve the cleaning efficiency of the cleaning device 100.

[0060] Preferably, the second driving component 70 is a water pump.

[0061] In some embodiments of this application, such as Figure 1 As shown, a cleaning channel is formed inside the flap 41, and the cleaning pipe 60 passes through the cleaning channel and is connected to the nozzle 411.

[0062] For example, one end of the cleaning channel is connected to the fixing hole 413, and the cleaning pipe 60 extends through the cleaning channel into the fixing hole 413 and is connected to the nozzle 411.

[0063] Therefore, the space occupied by the cleaning pipeline 60 and the flap 41 can overlap, making the component structure of the cleaning device 100 more compact, thereby further reducing the difficulty of arranging and designing the cleaning device 100.

[0064] The cleaning pipeline 60 includes a first pipeline 61 and a second pipeline 62. The first pipeline 61 passes through the cleaning channel, and the second pipeline 62 is connected between the first pipeline 61 and the cleaning medium container. The second pipeline 62 is a flexible hose.

[0065] In some embodiments of this application, such as Figure 1 As shown, a mounting hole is also formed on the housing 10, extending through the housing 10 along the thickness direction. The sensor assembly 20 includes a radar 21 and a protective housing 22. The protective housing 22 is sealed in the mounting hole. The radar 21 is connected to the side of the protective housing 22 facing the vehicle body. The protective housing 22 forms a window for the radar 21. In the cleaning position, the nozzle 411 is positioned facing the mounting hole, and the nozzle 411 and the radar 21 are respectively located on both sides of the protective housing 22 in the thickness direction of the housing 10.

[0066] During the operation of radar 21, the signal passes through the protective shell 22 and enters and exits the radar 21. When there are many impurities on the protective shell 22, it is necessary to clean the protective shell 22. The controller controls the flap 41 to rotate to the cleaning position, and the nozzle 411 sprays the cleaning medium toward the protective shell 22.

[0067] By setting up a protective shell 22, the radar 21 can be protected. By sealing the mounting hole with the protective shell 22, the radar 21 can transmit and receive signals normally. Furthermore, the radar 21 is located between the protective shell 22 and the vehicle body, which can reduce the probability of the radar 21 being damaged during operation.

[0068] The vehicle according to an embodiment of this application includes: the cleaning device 100 according to the first aspect of this application and the vehicle body, with the housing 10 connected to the vehicle body.

[0069] According to the embodiments of this application, by providing the cleaning device 100 according to the embodiments of this application, the cleaning effect on the sensor assembly 20 can be improved, thereby reducing the probability of sensor assembly 20 failure during operation and improving the reliability of the vehicle during operation.
