Description

Technical Field

[0001] This utility model relates to the field of windshield washer control technology, and in particular to a control device for repeatedly wiping the camera area with windshield washer blades. Background Technology

[0002] Most windshield wipers on the market have a fixed wiping area during operation, meaning the wiper arm has a fixed working stroke. However, with the increasing precision of monitoring systems such as electronic radar, there are also higher requirements for the clarity of the camera's field of view. Some manufacturers' windshield wipers have excessively long working strokes, which cannot effectively and quickly clean the camera's field of view, resulting in wasted power. Utility Model Content

[0003] The technical problem this utility model aims to solve is to address the issue that existing windshield wipers have a fixed wiping area during operation, resulting in excessively long working strokes, ineffective and inefficient cleaning of the camera's field of vision, and wasted power. This invention provides a control device for repeatedly wiping the camera area with water-spraying wiper blades, repeatedly spraying and wiping the camera area while not spraying other areas.

[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0005] A control device for repeatedly wiping a camera area with a washer-spray wiper blade includes a washer-spray wiper blade, a wiper motor that drives the washer-spray wiper blade to reciprocate and wipe the glass, and a wiper controller that controls the operation of the wiper motor. The wiper controller controls the operation of the wiper motor by controlling the output voltage. The wiper controller is powered by a battery and is communicatively connected to a water pump control module. The water pump control module controls the operation of the water pump, which is connected to the washer nozzle in the washer-spray wiper blade through a water pipe to spray water. The wiper controller is signal-connected to a detection module in the camera to receive signals from the detection module when it detects excessive dirt or dust on the windshield surface in the camera area. When the detection module detects excessive dirt or dust on the windshield surface in the camera area, it sends a "small-area multiple wipes on the camera area" command to the wiper control module via LIN communication. The washer-spray wiper blade then repeatedly wipes the windshield in the camera area during its entire wiping stroke from bottom to top.

[0006] In a preferred embodiment of this utility model, according to the pre-calibrated wiping angle range of the camera area, when the wiper controller receives a signal from the detection module in the camera that there is too much sewage or dust on the windshield surface in the camera area, the angle sensor in the wiper motor performs feedback control to limit the water-spraying wiper blades from reciprocating to wiping the windshield in the camera area.

[0007] In a preferred embodiment of this utility model, during the continuous reciprocating wiping action of the water-spraying wiper blade within the camera's imaging area, the detection module inside the camera will provide real-time feedback on the cleaning level. This cleaning level is adjusted according to a preset setting. When the wiping cleaning reaches this requirement, the detection module inside the camera will send a LIN communication signal to the wiper controller again, and the wiper controller will end the repetitive wiping action.

[0008] In a preferred embodiment of this utility model, the wiper controller has a LIN communication interface, which is connected to the water pump control module via LIN communication; the water pump control module is also connected to the water pump via LIN communication.

[0009] In a preferred embodiment of this utility model, a toggle switch is connected to the water pump control module.

[0010] By adopting the above technical solution, the water-spraying wiper blade of this utility model repeatedly wipes the windshield area within the camera area during the wiping process, so as to achieve a clear view of the camera, which not only shortens the working distance and saves energy, but also cleans the target area and achieves the target cleanliness.

[0012] Figure 2 This is a schematic diagram of the water-spraying wiper blade of this utility model repeatedly wiping the windshield area within the camera area. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] See Figure 1The figure shows a control device for segmented water spraying by windshield wiper blades. It includes a windshield wiper blade 10, a wiper motor 20 that drives the wiper blade 10 to reciprocate and wipe the glass 80, and a wiper controller 30 that controls the operation of the wiper motor 20. The wiper controller 30 controls the operation of the wiper motor 20 by controlling its output voltage. The wiper controller 30 is powered by a battery 40 and is communicatively connected to a water pump control module 50. The water pump control module 50 controls the operation of a water pump 60, which is connected to the spray nozzles in the windshield wiper blade 10 via a water pipe. The wiper controller 30 has a LIN communication interface 31, which is connected to the water pump control module 50 via LIN communication. The water pump control module 50 and the water pump 60 are also connected via LIN communication. A toggle switch 70 is connected to the water pump control module 50.

[0015] The wiper controller 30 is connected to the detection module 80 inside the camera to receive signals from the detection module 80 when it detects excessive water or dust on the surface of the windshield A area in the camera area. When the detection module 80 detects excessive water or dust on the surface of the windshield A area in the camera area, it sends a "small area multiple wipes in the camera area" command to the wiper control module via LIN communication. The water-spraying wiper blade 10 then repeatedly wipes the windshield A area in the camera area during its entire wiping stroke from bottom to top.

[0016] Based on the pre-calibrated wiping angle range of the windshield A area within the camera's field of view, when the wiper controller 30 receives a signal from the detection module 80 inside the camera that there is too much dirty water or dust on the surface of the windshield A area within the camera's field of view, the angle sensor inside the wiper motor 20 performs feedback control to limit the water-spraying wiper blades 10 from reciprocating to wiping the windshield A area within the camera's field of view.

[0017] During the continuous reciprocating wiping action of the water-spraying wiper blade 10 on the windshield A area within the camera area, the detection module 80 inside the camera will provide real-time feedback on the cleaning level. This cleaning level is adjusted according to a preset setting. When the wiping cleaning reaches this requirement, the detection module 80 inside the camera will send a LIN communication signal to the wiper controller 30 again, and the wiper controller 30 will stop the repetitive wiping action.

[0018] The water-spraying wiper blade of this invention repeatedly wipes the windshield area within the camera area during the wiping process, so as to achieve a clear view of the camera. This not only shortens the working distance and saves energy, but also cleans the target area and achieves the target cleanliness.
