The guide piece 3 and the wiping piece 4 can swing on the car window in a reciprocating way only by enabling the rotating piece 2 to drive the sliding block 5 to move; compared with the prior art that the wiper device needs the combined action of the intermediate shaft, the second connecting rod and the wiper shaft to enable the first connecting rod to drive the wiper piece to do reciprocating swing within a certain angle range, the wiping device for the whole car window needs fewer parts, and is simple in structure and high in assembly efficiency; and because the related middle parts are only the sliding blocks 5, the number of the sliding blocks is small, so that the probability of failure of the wiping device of the car window is greatly reduced; and through setting up slider 5, can make the swing motion of guide 3 comparatively stable to make the wiper device's of door window operating stability better.

Further, the wiping device for the vehicle window further comprises a driving member; the driving part is in driving connection with the rotating part 2, and the driving part is used for driving the rotating part 2 to rotate around the fixing part 1. This enables automatic wiping of the interior surface of the window. In other embodiments, a handle may be provided on the rotary member 2, and the inner surface of the window may be wiped by manually rotating the rotary member 2 through the handle. In this embodiment, the driving member may be any one of an air cylinder and an electric push rod. Taking the cylinder as an example, the body of the cylinder is rotatably arranged on the frame, and the cylinder rod of the cylinder is rotatably connected with the rotating part 2.

Alternatively, both the length of the wiper 4 and the length of the rotor 2 may be telescopic. In particular, the length of the wiper 4 matches the length of the rotor 2, and both match the passenger's viewing range requirements; the guide piece 3 can do reciprocating swing in different angle ranges by adjusting the length of the rotating piece 2, so that a proper swing angle can be found according to the specific situation in the car window; meanwhile, the length of the wiping part 4 on the guide part 3 can be adjusted, so that the range meeting the viewing requirements of passengers can be brushed. Exemplarily, taking the rotating member 2 as an example, the rotating member 2 includes a first rod and a second rod, the first rod is slidably sleeved on the second rod, the first rod and the second rod are respectively rotatably connected with the fixing member 1 and the slider 5, the first rod is provided with a spring pin, the second rod is provided with a plurality of pin holes at intervals along the length direction thereof, and the spring pin can be inserted into any one of the pin holes.

As shown in fig. 2, in the present embodiment, the wiping member 4 includes a wiping strip 41 for wiping the inner surface of the window, and a supporting member 42 for fixing the wiping strip 41, the supporting member 42 is mounted on the guide member 3, a water guiding groove is provided on the supporting member 42, and a micro-hole is provided on the wiping strip 41, the micro-hole is communicated with the water guiding groove, so that water wiped on the wiping strip 41 can directly flow into the water guiding groove through the micro-hole, so as to prevent wiping water on the wiping strip 41 from overflowing into the vehicle. The wiping strip 41 may be a sponge.

Further, as shown in fig. 2, the guide member 3 is provided with the accommodating cavity 31 and the communicating hole for communicating the accommodating cavity 31 and the water guiding groove, so that accumulated water in the water guiding groove can directly flow into the accommodating cavity 31 through the communicating hole, thereby preventing the accumulated water in the water guiding groove from overflowing into the vehicle, and ensuring that the riding experience of passengers is better.

Further, as shown in fig. 2, the wiping device for a vehicle window further includes a piston 62 and a first valve 61. Wherein, the piston 62 is arranged in the accommodating cavity 31, the piston 62 is in sliding fit with the guide member 3, and the piston 62 can slide back and forth in the accommodating cavity 31 along the length direction of the accommodating cavity 31; the first valve 61 is arranged in the accommodating cavity 31, and the first valve 61 is configured that when the piston 62 moves away from the wiping piece 4, the first valve 61 opens the communication hole to enable the accumulated water in the water guide groove to flow into the accommodating cavity 31 through the communication hole, so that the phenomenon that the accumulated water in the water guide groove is too much to continuously accommodate the water on the wiping strip 41 can be avoided; when the piston 62 moves closer to the wiper 4, the first valve 61 closes the communication hole to block the water guide groove from the accommodating chamber 31, and prevents the water in the accommodating chamber 31 from being squeezed out when the piston 62 moves. The direction in which water on the wiper 4 flows into the housing chamber 31 is shown by an arrow a in fig. 2.

Specifically, as shown in fig. 2 and 3, a stopper 32 is provided at a communication position of the accommodation chamber 31 and the communication hole; the first valve 61 includes a first valve plate 611 and a first elastic member, the first valve plate 611 is located between the stop member 32 and the piston 62, the first elastic member connects the first valve plate 611 and the inner wall of the accommodating cavity 31, and the first elastic member drives the first valve plate 611 to abut against the stop member 32. In this embodiment, the first elastic member may be any one of a torsion spring, a tension spring, and a compression spring. The stopper 32 is a stepped surface formed between the receiving chamber 31 and the communicating hole (the inner diameter of the receiving chamber 31 is larger than that of the communicating hole, and a stepped surface is formed therebetween), and the stopper 32 may be an annular projection protruding from the receiving chamber 31. In this embodiment, the first valve 61 is a mechanical valve, which can make the reliability of the opening or closing operation of the first valve 61 higher, and in other embodiments, the first valve 61 can be replaced by an electromagnetic valve, which needs to be noted that the mechanical valve has a lower cost than the electromagnetic valve.

The first valve 61 works as follows: when the piston 62 moves towards the wiper 4, the containing volume of the gas in the containing cavity 31 becomes smaller, the gas is compressed, the direction of the acting force given to the first valve plate 611 by the gas is the same as the direction of the acting force given to the first valve plate 611 by the first elastic member, at this time, the first valve plate 611 abuts against the stop member 32, the communication hole is closed, and the water can be prevented from flowing out of the containing cavity 31. When the piston 62 moves away from the wiper 4, the receiving volume of the gas in the receiving chamber 31 becomes large, the gas pressure decreases, the gas gives the first valve sheet 611 a suction force, the direction of the suction force is opposite to the direction of the urging force given to the first valve sheet 611 by the first elastic member, and when the suction force can overcome the urging force given to the first valve sheet 611 by the first elastic member, the first valve sheet 611 moves away from the stopper 32 with respect to the first elastic member to open the communication hole.

Specifically, a sliding groove communicated with the accommodating cavity 31 is further arranged in the guide 3, as shown in fig. 2, the piston 62 is provided with a connecting piece 65, the connecting piece 65 penetrates through the sliding groove and is connected with the slider 5, and the piston 62 is close to the wiper 4 relative to the connecting piece 65, so that the slider 5 can slide to drive the connecting piece 65 to move, and the connecting piece 65 drives the piston 62 to move in the accommodating cavity 31; and the piston 62 is always located between the chute and the wiper 4 to avoid air leakage and water leakage at the position where the piston 62 moves to the chute. In the embodiment, the sliding block 5 drives the piston 62 to move synchronously, so that a driving part for driving the piston 62 to move independently can be saved. In other embodiments, a motor may be provided on the guide 3 to drivingly connect the motor to the piston 62, such that the motor moves the piston 62.

The connecting member 65 is substantially U-shaped, one end of the U-shaped structure is located in the accommodating cavity 31 and connected to the piston 62, and the other end of the U-shaped structure passes through the sliding groove and is located outside the accommodating cavity 31 and connected to the slider 5. So set up, can guarantee that spout and piston 62 have certain interval in the length direction along guide 3, and then guarantee that the spout is located outside the motion range of piston 62, prevent that piston 62 from moving to the position department of spout from producing gas leakage, leaking.

As an alternative, the accommodating cavity 31 is provided with an opening at an end far away from the wiper 4, one end of the U-shaped structure is located in the accommodating cavity 31 and connected with the piston 62, and the other end of the U-shaped structure bypasses the opening and is located outside the accommodating cavity 31 and connected with the slider 5. The U-shaped structure can ensure that a certain moving space is formed between the guide part 3 and the connecting part 65, so that in the process that the sliding block 5 drives the connecting part 65 to move, the connecting part 65 and the guide part 3 cannot generate interference.

Further, as shown in fig. 2, the wiping device for the vehicle window further includes a water collecting box 63 and a water discharging pipe 66, a water discharging port communicated with the accommodating cavity 31 is further provided on the guide member 3, an inlet of the water discharging pipe 66 is communicated with the water discharging port, the piston 62 is always located on one side of the water discharging port far away from the wiping member 4, and an outlet of the water discharging pipe 66 is communicated with the water collecting box 63; when the water accumulated in the accommodating chamber 31 is excessive, the water accumulated in the accommodating chamber 31 can be directly discharged into the water collecting box 63 through the water discharge port and the water discharge pipe 66.

As shown in fig. 2, the wiping device for a vehicle window further includes a second valve 64 disposed at the drain port, the second valve 64 is configured such that when the piston 62 moves away from the wiping member 4, the second valve 64 closes the drain port, the accommodating chamber 31 does not leak air from the drain port, and the piston 62 is not affected to suck water in the water guide groove into the accommodating chamber 31; when the piston 62 moves closer to the wiper 4, the second valve 64 opens the drain opening, and the piston 62 pushes the water in the accommodating chamber 31 from the drain opening to the drain pipe 66 for draining. Wherein the direction in which the water in the accommodating chamber 31 is discharged into the water collecting box 63 is shown by an arrow B in fig. 2.

Specifically, as shown in fig. 2 and fig. 3, the second valve 64 includes a second valve plate 641 and a second elastic member, the second valve plate 641 is rotatably disposed on the outer surface of the guide 3, the second elastic member connects the second valve plate 641 and the outer surface of the guide 3, and the second elastic member drives the second valve plate 641 to abut against the outer surface of the guide 3 to close the drain opening. In this embodiment, the second elastic member may be any one of a torsion spring, a tension spring, and a compression spring. In this embodiment, the second valve 64 is a mechanical valve, which can make the reliability of the opening or closing operation of the second valve 64 higher, and in other embodiments, the second valve 64 may be replaced by a solenoid valve, which is noted that the mechanical valve has a lower cost than the solenoid valve.

The working principle of the second valve 64 is similar to that of the first valve 61, and the specific working principle of the second valve may refer to the first valve 61, which is not described herein again in detail. When the piston 62 moves closer to the wiper 4, the second valve plate 641 moves away from the outer surface of the guide 3 relative to the second elastic member, and the water outlet is opened to discharge the water in the accommodating chamber 31 into the water collecting box 63. When the piston 62 moves away from the wiper 4, the second valve plate 641 abuts against the outer surface of the guide 3 to close the drain opening.

Further, as shown in fig. 2, the drain pipe 66 is slidably disposed through the slider 5 and connected to the water collecting box 63, so that the drain pipe 66 can limit the rotation of the slider 5, and the drain pipe 66, the guide 3, and the rotation member 2 can act on each other to prevent the slider 5 from rotating in the sliding process, thereby better limiting the rotation of the slider 5.

The operation of the wiping device for a vehicle window in the present embodiment is as follows:

when water mist appears on the inner surface of the vehicle window: firstly, the driving piece works to enable the driving piece to drive the rotating piece 2 to rotate around the fixed piece 1; then, the rotating part 2 drives the guide part 3 to perform reciprocating swing within a certain angle range on the vehicle window through the sliding block 5 so as to drive the wiping part 4 on the guide part 3 to perform reciprocating swing on the vehicle window, so that the wiping strip 41 of the wiping part 4 wipes water mist on the vehicle window.

Then, the water wiped on the wiping strip 41 directly flows into the water guide groove through the minute holes.

Wherein, in the sliding process of the sliding block 5, the sliding block 5 drives the piston 62 to move synchronously through the connecting piece 65: when the piston 62 is moved away from the wiper 4, the first valve 61 is opened, the second valve 64 is closed, and water in the water guide channel is sucked into the accommodating chamber 31 to perform a water sucking operation. When the piston 62 is moved closer to the wiper 4, the first valve 61 is closed, the second valve 64 is opened, and the piston 62 pushes the water in the accommodating chamber 31 to be discharged from the water discharge port into the water discharge pipe 66 for the water discharge operation.

And finally, after the passenger obtains a satisfactory window viewing range, stopping the driving piece to complete the whole wiping working process of the window wiping device.

The embodiment also provides an automobile comprising the wiping device of the window, and the wiping device of the window is arranged on the inner surface of the window of the automobile. The vehicle window can be a front windshield, a rear windshield, and windshields on the left and right sides.
