[0025] In related technologies, vehicle windshield cleaning systems primarily clean the windshield through the reciprocating motion of wipers combined with detergent sprayed from nozzles. However, existing windshield cleaning systems generally have wiper blind spots, especially in the area near the A-pillar trim. Due to the limited travel of the wiper blades, dirt in this area is difficult to remove directly, becoming a cleaning dead zone. Currently, the only way to solve the wiper blind spot is through manual cleaning after parking; it cannot be cleaned while driving, increasing the driver's blind spot near the A-pillar and affecting vehicle safety.

[0026] Reference Figure 1 , Figure 2 and combined Figure 4 , Figure 5 , Figure 1 and Figure 4 The following are schematic diagrams of the windshield cleaning system in embodiments of the present invention. Figure 2 This is an assembly diagram of the first nozzle 300 and the second nozzle 500 according to an embodiment of the present invention. Figure 5 This is an assembly diagram of the first nozzle 300 and the A-pillar trim 200 according to an embodiment of the present invention. Figure 1 and Figure 2 The windshield wiper 400 is at its highest position. Figure 4The windshield wiper 400 is in its lowest position. As shown in the figure, a first aspect embodiment of the present invention provides a windshield cleaning system for cleaning a windshield 100. The windshield cleaning system includes an A-pillar trim 200, a first nozzle 300, a wiper assembly, and a second nozzle 500. The A-pillar trim 200 extends along a first direction and is connected to one side of the windshield 100. The first nozzle 300 is connected to the A-pillar trim 200 and has a first outlet. The wiper assembly includes a drive member and a wiper 400. The wiper 400 abuts against the windshield 100. The drive member drives the wiper 400 to rotate upwards, so that the wiper 400 moves to its highest position. Alternatively, the drive member can be used to... The windshield wiper 400 is driven to rotate downwards to move to its lowest position. The second nozzle 500 is connected to the windshield wiper 400. When the windshield wiper 400 is at its highest position, the first outlet faces the windshield wiper 400 and the second outlet faces the A-pillar trim 200. Both the first and second outlets can spray cleaning medium onto the area of ​​the windshield 100 between the windshield wiper 400 and the A-pillar trim 200. The spray areas of the first nozzle 300 and the second nozzle 500 are arranged along a first direction. In this way, dirt can be cleaned from the area of ​​the windshield 100 near the A-pillar trim 200, eliminating blind spots during driving and improving vehicle safety.

[0027] For example, when there are stains on the windshield 100 near the A-pillar trim 200, the first nozzle 300, the second nozzle 500, and the wiper assembly are activated. Both the first and second outlets spray cleaning media onto the windshield 100 to clean the stains on the windshield 100 near the A-pillar trim 200. When the drive unit drives the wiper 400 to rotate to the highest position, the spray areas of the first nozzle 300 and the second nozzle 500 are arranged along the first direction, which can increase the cleaning area of ​​the cleaning media on the windshield 100 near the A-pillar trim 200 to clean the stains on the windshield 100 near the A-pillar trim 200. This can eliminate blind spots during driving and improve vehicle safety.

[0028] It should be noted that the first direction is roughly along the Z-axis of the vehicle, which is the height direction of the vehicle. The axis of the first outlet forms a certain angle with the surface of the windshield 100, and the axis of the second outlet forms a certain angle with the surface of the windshield 100.

[0029] It should be noted that the first nozzle 300 and the second nozzle 500 can be fan-shaped nozzles or columnar nozzles. The specific structure of the first nozzle 300 and the second nozzle 500 is common knowledge to those skilled in the art and will not be described in detail here.

[0030] It should be noted that the driving component can be a stepper motor or a servo motor, etc. Specific implementation methods can be adjusted according to actual needs and are not limited here.

[0031] It should be noted that the first nozzle 300 can be fixedly connected to the A-pillar trim 200 by snap-fit ​​or threaded connection, and the second nozzle 500 can be fixedly connected to the wiper 400 by snap-fit ​​or threaded connection, without limitation.

[0032] like Figure 1 , Figure 2 As shown, in this embodiment, three first nozzles 300 are configured, arranged along a first direction. Two second nozzles 500 are configured. When the wiper 400 is in its highest position, the spray areas of the two second nozzles 500 are located between the spray areas of the two adjacent first nozzles 300, which can increase the cleaning area of ​​the cleaning medium in the area of ​​the windshield 100 near the A-pillar trim 200 and expand the coverage of the cleaning medium to clean the stains in the area of ​​the windshield 100 near the A-pillar trim 200, thereby improving the safety of vehicle use.

[0033] For example, when the wiper 400 is in its highest position, the first nozzle 300 and the second nozzle 500 are staggered along the first direction, and the spray area of ​​the second nozzle 500 is located between the spray areas of two adjacent first nozzles 300. This allows the cleaning medium sprayed from the second outlet to clean the area of ​​the windshield 100 between the spray areas of adjacent first nozzles 300, thereby increasing the cleaning area of ​​the cleaning medium in the area of ​​the windshield 100 near the A-pillar trim 200 and expanding the coverage of the cleaning medium to clean the stains in the area of ​​the windshield 100 near the A-pillar trim 200, thereby improving the vehicle's safety.

[0034] It is understandable that when there are two first nozzles 300 and one second nozzle 500, the spray area of ​​the second nozzle 500 is located between the spray areas of the two adjacent first nozzles 300.

[0035] As another implementation, there are two first nozzles 300 and three second nozzles 500. When the wiper 400 is in the highest position, the spray area of ​​the first nozzle 300 is located between the spray areas of the two adjacent second nozzles 500, which can also increase the cleaning area of ​​the cleaning medium in the area of ​​the windshield 100 near the A-pillar trim 200. This is not limited here.

[0036] In another implementation, when the wiper 400 is in its highest position, a portion of the spray area of ​​the second nozzle 500 overlaps with the spray area of ​​the first nozzle 300, which can eliminate the gap between the spray areas of the second nozzle 500 and the first nozzle 300. The spray areas of the first nozzle 300 and the second nozzle 500 can completely cover the area of ​​the windshield 100 near the A-pillar trim 200, increasing the cleaning area of ​​the cleaning medium in the area of ​​the windshield 100 near the A-pillar trim 200, so as to clean the stains in the area of ​​the windshield 100 near the A-pillar trim 200.

[0037] Of course, in other specific embodiments, the first nozzle 300 may be configured with one, two or four, and the second nozzle 500 may be configured with one, three or four. The number of the first nozzle 300 and the second nozzle 500 can be adjusted according to actual needs, and no limitation is made here.

[0038] Reference Figure 6 , Figure 6 This is a schematic diagram of the assembly of the windshield wiper 400 and the second nozzle 500 according to an embodiment of the present invention. As shown in the figure, in this embodiment, the windshield wiper 400 includes a rocker arm 410 and a wiper blade 420. The wiper blade 420 is connected to the rocker arm 410 and has a long strip structure. The output end of the drive unit is connected to the rocker arm 410. The second nozzle 500 is connected to the rocker arm 410. The wiper blade 420 is used to abut against the windshield 100. Among the three first nozzles 300, the first nozzles 300 at both ends along the first direction are the top nozzle and the bottom nozzle. When the windshield wiper 400 is in the highest position, the top nozzle is higher than the bottom nozzle. The highest point of the wiper blade 420 is located within the spray area of ​​the top nozzle, and the lowest point of the wiper blade 420 is located within the spray area of ​​the bottom nozzle. The top nozzle can clean the area of ​​the windshield 100 above the highest point of the wiper blade 420, and the bottom nozzle can clean the area of ​​the windshield 100 below the lowest point of the wiper blade 420, so as to eliminate the movement traces of the highest and lowest points of the wiper blade 420 and avoid affecting the driving visibility.

[0039] For example, taking the driver's cabin as being on the left side of the vehicle, the A-pillar trim 200 is located on the left side of the windshield 100. When the wiper 400 is in its highest position, the length direction of the wiper blade 420 is parallel to the first direction, that is, the A-pillar trim 200 and the wiper blade 420 are arranged along the second direction, which is roughly the Y-axis direction of the vehicle. The first nozzle 300 and the second nozzle 500 are arranged opposite each other in the left-right direction. The outlet of the first nozzle 300 faces to the right, and the outlet of the second nozzle 500 faces to the left. The spray area of ​​the top nozzle can cover the highest point of the wiper blade 420, which can clean the dirt on the windshield 100 above the highest point of the wiper blade 420. The spray area of ​​the bottom nozzle can cover the lowest point of the wiper blade 420, which can clean the dirt on the windshield 100 below the lowest point of the wiper blade 420, so as to eliminate the movement traces of the highest and lowest points of the wiper blade 420 and avoid affecting the driving visibility.

[0040] It should be noted that when the wiper 400 is in its lowest position, the outlet of the second nozzle 500 is set upward. At this time, the cleaning medium sprayed by the second nozzle 500 acts on the area of ​​the windshield 100 within the travel range of the wiper 400, which can pre-wet the windshield 100, which is beneficial for the wiper blade 420 to clean the windshield 100, thereby improving the cleaning effect of the windshield 100.

[0041] It should be noted that the left and right directions refer to the width of the vehicle. When the driver's cabin is located on the right side of the vehicle, the A-pillar trim 200 is located on the right side of the windshield 100.

[0042] Understandably, the wiper blade 420 is detachably connected to the rocker arm 410. After the wiper blade 420 wears out, the user can replace it with a new one without replacing the rocker arm 410, which can reduce the maintenance cost of the wiper 400.

[0043] In this embodiment, when the drive unit drives the wiper 400 to rotate upward, the first nozzle 300 and the second nozzle 500 operate. On the one hand, the second nozzle 500 can pre-wet the area of ​​the windshield 100 within the travel range of the wiper 400. The cleaning medium sprayed by the first nozzle 300 can lift up the dirt on the windshield 100. At this time, the wiper 400 hits the lifted dirt and can knock the lifted dirt to the A-pillar trim 200 or the outside of the A-pillar trim 200, which can efficiently clean the dirt attached to the area of ​​the windshield 100 near the A-pillar trim 200.

[0044] In this embodiment, when the drive unit drives the wiper 400 to rotate downward, the first nozzle 300 and the second nozzle 500 stop operating. On the one hand, this can save cleaning medium and reduce waste; on the other hand, it can prevent the newly sprayed cleaning medium from affecting the driver's visibility, thereby improving the vehicle's safety.

[0045] In this embodiment, the wiper 400 has a first position, which is located between the lowest position and the highest position. When the wiper 400 rotates from the lowest position to the first position, the first nozzle 300 stops operating. When the wiper 400 rotates from the first position to the highest position, the first nozzle 300 operates. This can save cleaning media and reduce waste, so as to achieve efficient cleaning of stains in the area of ​​the windshield 100 near the A-pillar trim 200.

[0046] For example, the first position is when the wiper 400 moves halfway through its stroke. During the stroke of the wiper 400 from the lowest position to the first position, the first nozzle 300 stops operating, which can reduce the waste of cleaning media. During the stroke of the wiper 400 from the first position to the highest position, the first nozzle 300 operates. The cleaning media sprayed by the first nozzle 300 can lift up the dirt adhering to the windshield 100. The wiper 400 can hit the lifted dirt and can knock the lifted dirt to the A-pillar trim 200 or the outside of the A-pillar trim 200.

[0047] It should be noted that the position of the wiper 400 can be detected by detecting the rotation duration or rotation angle of the wiper 400. The rotation angle of the wiper 400 can be detected by an angle sensor, and the rotation duration of the wiper 400 can be detected by a displacement sensor, which will not be described in detail here.

[0048] In this embodiment, when the wiper 400 is in its highest position, the wiper 400 remains in place for a first predetermined duration, and the first nozzle 300 and the second nozzle 500 operate for a second predetermined duration, the second predetermined duration being less than or equal to the first predetermined duration. On the one hand, the wiper 400 can prevent the cleaning medium sprayed from the first outlet from obstructing the driver's view; on the other hand, it can perform deep cleaning on the area of ​​the windshield 100 near the A-pillar trim 200, thereby improving the cleaning effect of the first nozzle 300 and the second nozzle 500.

[0049] For example, if the second predetermined duration is 1 second and the first predetermined duration is 1.5 seconds, when the wiper 400 is in its highest position, the first nozzle 300 and the second nozzle 500 operate for 1 second. Afterward, the first nozzle 300 and the second nozzle 500 stop operating, and the wiper 400 remains in its highest position for 0.5 seconds. The wiper 400 can prevent the cleaning medium sprayed from the first outlet from obstructing the driver's view, thereby improving vehicle driving safety. Furthermore, when both the second and first predetermined durations are 1 second, after the first nozzle 300 and the second nozzle 500 operate for 1 second, the wiper 400 moves downward, and the first nozzle 300 and the second nozzle 500 stop operating, which also prevents the cleaning medium sprayed from the first outlet from obstructing the driver's view.

[0050] Reference Figure 7 , Figure 7 This is a schematic diagram of the structure of the first nozzle 300 in an embodiment of the present invention. As shown in the figure, in this embodiment, when the wiper 400 moves from the lowest position to the highest position, the first nozzle 300 sprays liquid and gas. The liquid is detergent, and the gas is high-pressure air. The high-pressure air carries the detergent to form a jet with better atomization effect, which can enhance the scouring force on the windshield 100 and help clean the stains attached to the windshield 100.

[0051] In this embodiment, during the process of the wiper 400 moving from the lowest position to the highest position, the second nozzle 500 sprays liquid. When the wiper 400 is at the highest position, the second nozzle 500 sprays liquid and gas. The liquid is detergent, and the gas is high-pressure air. The high-pressure air carries the detergent to form a jet with better atomization effect, which can enhance the scouring force on the windshield 100 and help clean the stains attached to the windshield 100.

[0052] It should be noted that the vehicle's washer fluid storage tank is connected to the first nozzle 300 and the second nozzle 500 via the first and second pipelines, respectively. The output end of the vehicle's high-pressure air pump is connected to the first nozzle 300 and the second nozzle 500 via the third and fourth pipelines, respectively. The first pipeline is equipped with a first solenoid valve, which is used to control the opening and closing of the first pipeline. The second pipeline is equipped with a second solenoid valve, which is used to control the opening and closing of the second pipeline. The third pipeline is equipped with a third solenoid valve, which is used to control the opening and closing of the third pipeline. The fourth pipeline is equipped with a fourth solenoid valve, which is used to control the opening and closing of the fourth pipeline. Details will not be provided here.

[0053] In this embodiment, the windshield cleaning system also includes a control module and a detection module. The first nozzle 300, the second nozzle 500, the drive unit, and the detection module are electrically connected to the control module. The detection module is used to detect whether there are stains on the side of the windshield 100 near the A-pillar trim 200. The control module controls whether the first nozzle 300, the second nozzle 500, and the drive unit operate according to the detection signal from the detection module, which can realize the automated operation of the windshield 100 cleaning system, thereby improving the user experience.

[0054] For example, when the detection module detects stains on the side of the windshield 100 near the A-pillar trim 200, the detection module sends a first detection signal to the control module. The control module controls the first nozzle 300, the second nozzle 500, and the drive unit to operate according to the first detection signal, so that the cleaning medium sprayed by the first nozzle 300 and the second nozzle 500 can act on the area of ​​the windshield 100 near the A-pillar trim 200 to clean the stains. After the stains are cleaned, the detection module sends a second detection signal to the control module. The control module controls the first nozzle 300, the second nozzle 500, and the drive unit to stop operating according to the second detection signal. This can realize the automated operation of the windshield 100 cleaning system, thereby improving the user experience.

[0055] It should be noted that the detection module can be a camera or light transmittance sensor inside the vehicle body, and the control module can be the whole vehicle control system, without any restrictions.

[0056] In this embodiment, the first outlet is tilted downwards, and the cleaning medium sprayed from the first outlet can flow downwards along the surface of the windshield 100 with the assistance of gravity. This can accelerate the downward flow of the cleaning medium, thereby driving the stains downwards and facilitating the cleaning of the stains.

[0057] like Figure 1 As shown in this embodiment, when the wiper 400 is in the highest position, the second outlet is tilted downwards. The dirt can be washed away by the cleaning medium sprayed from the first outlet and the cleaning medium sprayed from the second outlet, which accelerates the downward flow of the cleaning medium and improves the cleaning effect of the windshield 100.

[0058] A second aspect of the present invention provides a vehicle including a body, a windshield 100, and a windshield cleaning system according to a first aspect of the present invention. The windshield 100 is mounted on the body, and the A-pillar trim 200 and the wiper assembly are also mounted on the body. The A-pillar trim 200 is connected to one side of the windshield 100, and the wiper 400 abuts against the windshield 100. It can clean dirt from the area of ​​the windshield 100 near the A-pillar trim 200, eliminate blind spots during driving, and thus improve the safety of vehicle use.

[0059] For example, when there are stains on the windshield 100 in the area near the A-pillar trim 200, the first nozzle 300, the second nozzle 500, and the wiper assembly are activated. Both the first and second outlets spray cleaning media onto the surface of the windshield 100 to clean the stains in the area near the A-pillar trim 200. When the drive unit drives the wiper 400 to rotate to the highest position, the spray areas of the first nozzle 300 and the second nozzle 500 are arranged along the first direction, which can increase the cleaning area of ​​the cleaning media on the windshield 100 in the area near the A-pillar trim 200 to clean the stains in the area near the A-pillar trim 200 of the windshield 100. This can eliminate blind spots during driving and improve vehicle safety.
