Vehicle behavior recognition and prediction is a key technology, and machine vision technology has broad application prospects. Machine vision technology includes image acquisition devices (such as cameras), which capture environmental information for subsequent processing and analysis.

[0003] However, after a period of use, dust tends to accumulate on the lens surface, reducing the accuracy of the collected data. Furthermore, the camera cannot be cleaned while driving. Some vehicles are equipped with a lens cleaning function, which uses a nozzle installed near the camera to clean dirt from the lens surface. However, existing nozzles cannot be retracted into the vehicle before and after use. Once installed, they protrude from the vehicle exterior, affecting the overall aesthetics. Utility Model Content

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 6 The present invention provides a cleaning mechanism for cleaning a camera on a vehicle, comprising: a liquid storage tank 1, a water pump 2 and a telescopic assembly 3. The water pump 2 is connected to the liquid storage tank 1 through a first pipe 11. The first pipe 11 is used to transport the liquid in the liquid storage tank 1 to the water pump 2 for pressurization. The telescopic assembly 3 comprises a base 31, a drive motor 32, a crank 33, a sliding sleeve 34 and a telescopic rod 35. The crank 33 is provided at the power output end of the drive motor 32. One end of the telescopic rod 35 is connected to the crank The handle 33 is rotatably connected, and the other end is connected to the water outlet end of the second pipe 12. The water inlet end of the second pipe 12 is connected to the water pump 2. The sleeve 34 is slidably mounted on the rod body of the telescopic rod 35. The sleeve 34 is rotatably connected to the base 31. The drive motor 32 is used to drive the crank 33 to rotate so that the telescopic rod 35 drives the water outlet end of the second pipe 12 to extend out of the vehicle. The water pump 2 is used to pressurize the liquid to spray the mirror of the camera through the water outlet end of the second pipe 12.

[0022] In the present application, the central axis of the rotational connection between the crank 33 and the telescopic rod 35 is not aligned with the central axis of the power output of the drive motor 32. Therefore, when the drive motor 32 drives the crank 33 to rotate, the central axis of the rotational connection between the crank 33 and the telescopic rod 35 rotates about the central axis of the power output of the drive motor 32. Accordingly, the central axis of the telescopic rod 35 is not aligned during the rotation of the crank 33, and the direction of the central axis of the telescopic rod 35 is constantly changing. In the present application, the sliding sleeve 34 can support the telescopic rod 35. Because the sliding sleeve 34 is in sliding connection with the telescopic rod 35, the central axis of the sliding sleeve 34 is not aligned during the rotation of the crank 33, and the direction of the central axis of the telescopic rod 35 is constantly changing. Therefore, the sliding sleeve 34 needs to be rotatably connected to the base 31 to match the changes in its central axis.

[0023] It is worth noting that when the central axis of the telescopic rod 35 and the central axis of the power output end of the drive motor 32 are located in the same plane and the central axis of the telescopic rod 35 is located behind the central axis of the power output end of the drive motor 32, the telescopic rod 35 is in a retracted state and the water outlet end of the second pipe 12 is hidden inside the vehicle; when the central axis of the telescopic rod 35 and the central axis of the power output end of the drive motor 32 are located in the same plane and the central axis of the telescopic rod 35 is located in front of the central axis of the power output end of the drive motor 32, the telescopic rod 35 is in an extended state and the water outlet end of the second pipe 12 is exposed outside the vehicle.

[0024] In the present application, during the extension and retraction of the telescopic rod 35, the water outlet end of the second pipe 12 can maintain a state of continuous water discharge, thereby spraying the camera in all directions to improve the cleaning effect.

[0025] In one feasible embodiment, the sliding sleeve 34 includes a sliding portion 341 and a rotating portion 342, which are vertically connected. The sliding portion 341 is slidably mounted on the body of the telescopic rod 35, and the rotating portion 342 is rotatably connected to the base 31 via a first bearing. In this embodiment, the first bearing supports the rotating portion 342, reducing friction between the rotating portion 342 and the base 31 through rolling, thereby reducing wear and improving efficiency. During the extension and retraction of the telescopic rod 35, the central axis of the sliding portion 341 overlaps with the central axis of the telescopic rod 35 and their directions continuously change, while the central axis of the rotating portion 342 remains in the same position.

[0026] In one feasible embodiment, the telescopic rod 35 is connected to the water outlet end of the second pipe 12 via a connecting sleeve 4, and the connecting sleeve 4 is detachably connected to the telescopic rod 35. In this embodiment, the detachable connection between the connecting sleeve 4 and the telescopic rod 35 allows the direction of the water outlet end of the second pipe 12 to be adjusted.

[0027] Specifically, the connecting sleeve 4 includes a connecting end 41 and a sleeve end 42. The connecting end 41 and the sleeve end 42 are connected. The connecting end 41 defines a through hole 411 for inserting the second pipe 12. The through hole 411 is configured to interference fit with the second pipe 12 to secure the second pipe 12 to the connecting end 41. The sleeve end 42 defines a countersunk hole 421 and a threaded hole 422. The countersunk hole 421 is defined along the axis of the telescopic rod 35, while the threaded hole 422 is defined along the radial direction of the telescopic rod 35. The countersunk hole 421 allows the telescopic rod 35 to be inserted, and the threaded hole 422 is configured to be threadedly engaged with a bolt 423 to secure the sleeve end 42 to the telescopic rod 35. In this embodiment, the sleeve end 42 can be loosened by tightening the bolt 423, allowing the sleeve end 42 to rotate on the end of the telescopic rod 35. Once the sleeve end 42 is rotated to a desired position, the bolt 423 can be tightened to secure the sleeve end 42.

[0028] In one feasible embodiment, the drive motor 32 includes a transmission shaft 321. The base 31 is provided with a plurality of second bearings 311, which are spaced apart along the axial direction of the transmission shaft 321. The transmission shaft 321 sequentially passes through the plurality of second bearings 311 and is connected to the crank 33. The plurality of second bearings 311 can increase the support force of the transmission shaft 321 and prevent the transmission shaft 321 from deflecting during rotation, which could cause the axis of rotation to deviate.

[0029] In one feasible embodiment, a cover 5 is further included. The cover 5 is configured to cover the base 31. A waist-shaped hole 51 is defined between the base 31 and the cover 5. The waist-shaped hole 51 allows the telescopic rod 35 to pass through and swing. Since the telescopic rod 35 swings continuously during extension and retraction, the waist-shaped hole 51 provides space for the telescopic rod 35 to swing. The cover 5 protects the components within the base 31.

[0030] The present invention also provides a vehicle including any of the cleaning mechanisms described above, wherein the vehicle has a window 6 through which the telescopic rod 35 extends, and a baffle 7 is hingedly connected to the window 6, the baffle 7 being configured to shield the window 6. When the telescopic rod 35 is extended, the baffle 7 can be pressed against the window 6, causing it to flip upward. Because the end of the telescopic rod 35 is connected to the second pipe 12, the second pipe 12 is likely to come into contact with the baffle 7 during the extension process. Therefore, the second pipe 12 can be made of a relatively rigid hose to prevent the baffle 7 from squeezing and deforming the second pipe 12. Alternatively, a support plate can be provided at the end of the telescopic tube to protect the baffle 7 from being squeezed. Furthermore, the baffle 7 is magnetic. When the telescopic rod 35 is retracted, the baffle 7 flips downward under the action of gravity and is attracted to the window 6 by magnetic force. The baffle 7 shields the window 6, preventing the external environment from affecting the cabin.
