[0002] When driving a vehicle on a highway or a national or provincial road in rainy weather at a high speed, when the tires of the vehicle in front rotate, the sewage and rainwater on the road surface are carried up and adhered to the rear window glass and the mirror surface of the rearview mirror. The window and the rearview mirror will become blurred. The driver in the cab cannot observe the road conditions behind the vehicle through the window and the rearview mirror, so that it is impossible to ensure safety when changing lanes and turning. In rainy weather, there is no windshield wiper on the window and the rearview mirror, and the sewage and rainwater adhered to the window glass and the rearview mirror cannot be cleaned and wiped in time.

[0026] Embodiment

[0027] Such as Figure 1 And Figure 2As shown in the figure, a pneumatic magnetic coupling type windshield wiper proposed by the utility model includes a cylinder body 1 installed on the outer body of the vehicle. The cylinder body 1 includes a fixing plate 11 fixedly installed on the outer body of the vehicle. The fixing plate 11 is fixed by passing screws through the screw holes on it. On the side of the fixing plate 11 away from the vehicle body, two groups of fixing blocks 12 are installed. The positions of the fixing blocks 12 are fixed and are respectively fixed at both ends of the fixing plate 11. A cylinder 13 is fixedly connected between the two groups of fixing blocks 12. A strong magnetic piston 14 is slidably connected in the cylinder 13, which is used to move the strong magnetic piston 14 when the pressure difference above and below the strong magnetic piston 14 changes. A sliding block 15 is also slidably sleeved on the outer ring of the cylinder 13. The strong magnetic piston 14 has strong magnetism, and the sliding block 15 and the strong magnetic piston 14 attract each other. When the strong magnetic piston 14 moves, it drives the sliding block 15 to move synchronously.

[0028] Furthermore, the above windshield wiper further includes a pneumatic component 2, which is used to drive the strong magnetic piston 14 to slide in the cylinder 13. The pneumatic component 2 includes a reversing switch 21 installed in the cab, and the reversing switch 21 is fixed in the cab. On one side of the reversing switch 21, two groups of connectors 22 are provided. Connecting air pipes 23 are installed in both groups of connectors 22. The ends of the two groups of connecting air pipes 23 away from the connectors 22 are respectively fixedly connected with connecting joints 24. The two groups of connecting joints 24 are respectively arranged in the fixing blocks 12, and one end of the connecting joint 24 is communicated with the cylinder 13. The reversing switch 21 changes the air pressure above and below the strong magnetic piston 14 in the cylinder 13 through the connecting air pipes 23, thereby driving the strong magnetic piston 14 to move up and down. An operating rod 25 is installed on the reversing switch 21, which is used to switch the positions of inflation and exhaust. On the side of the reversing switch 21 away from the connectors 22, two groups of exhaust holes 26 corresponding to the connectors 22 are provided for exhaust. An air inlet hole 27 is also provided between the two groups of exhaust holes 26. The air inlet hole 27 is connected to the vehicle-mounted air storage cylinder to provide power for the movement of the strong magnetic piston 14. After the vehicle-mounted air storage cylinder enters the reversing switch 21 through the air inlet hole 27, when inflating the upper part of the strong magnetic piston 14 through the upper connector 22, connecting air pipe 23, and connecting joint 24, the gas below the strong magnetic piston 14 is discharged through the lower connecting joint 24, connecting air pipe 23, connector 22, and exhaust hole 26. At this time, the strong magnetic piston 14 moves downward. After the vehicle-mounted air storage cylinder enters the reversing switch 21 through the air inlet hole 27, when inflating the lower part of the strong magnetic piston 14 through the lower connector 22, connecting air pipe 23, and connecting air pipe 23, the gas above the strong magnetic piston 14 is discharged through the upper connecting joint 24, connecting air pipe 23, connector 22, and exhaust hole 26. At this time, the strong magnetic piston 14 moves upward.

[0029] Further, the above windshield wiper further includes a cleaning assembly 3 fixedly connected to the sliding block 15. The cleaning assembly 3 is used to move synchronously with the sliding block 15 and clean the vehicle window. The cleaning assembly 3 includes a connecting plate 31 disposed on one side of the sliding block 15. A sliding groove 32 is formed in the connecting plate 31. Two fixing bolts 33 are disposed in the sliding groove 32. The fixing bolts 33 are threadedly connected to the sliding block 15, facilitating fixing the connecting plate 31 to the side of the sliding block 15, so that when the sliding block 15 moves, it drives the connecting plate 31 to move synchronously. At the same time, the setting of the sliding groove 32 facilitates adjusting the contact position between the wiper blade 36 and the glass. A mounting plate 34 is rotatably connected to one side of the connecting plate 31 close to the fixing plate 11. One end of the mounting plate 34 away from the connecting plate 31 is rotatably connected to a mounting bracket 35. A wiper blade 36 is mounted on one side of the mounting bracket 35 away from the mounting plate 34, and its function is to drive the wiper blade 36 to move synchronously when the sliding block 15 moves, so that when the wiper blade 36 moves, it can scrape off the sewage and rainwater on the vehicle window or rearview mirror. A tension spring 37 is connected between the connecting plate 31 and the mounting plate 34, which is used to release elastic force to ensure that the wiper blade 36 is in full contact with the surface to be cleaned.

[0030] In this embodiment, when driving on a rainy day, when turning or changing lanes, the driver swings the operating lever 25 up and down in the cab. After the on-vehicle air storage tank enters the reversing switch 21 through the air inlet hole 27, when the gas fills the upper part of the strong magnetic piston 14 through the upper connector 22, the connecting air pipe 23, and the connecting joint 24, the gas below the strong magnetic piston 14 is discharged through the lower connecting joint 24, the connecting air pipe 23, the connector 22, and the exhaust hole 26. At this time, the strong magnetic piston 14 moves downward. Thus, the strong magnetic piston 14 attracts the sliding block 15 to move downward synchronously, and drives the contact position of the wiper blade 36 with the outer surface of the vehicle window to move downward. When starting to fill the lower part of the strong magnetic piston 14 with gas through the lower connector 22 and the connecting air pipe 23, the gas above the strong magnetic piston 14 is discharged through the upper connecting joint 24, the connecting air pipe 23, the connector 22, and the exhaust hole 26. At this time, the strong magnetic piston 14 moves upward, and at this time the wiper blade 36 moves upward. Thus, the wiper blade 36 moves up and down as the driver swings the operating lever 25, realizing the up and down movement of the wiper blade 36, thereby cleaning the surface of the vehicle window or rearview mirror, facilitating observing the vehicles and pedestrians behind, and preventing traffic accidents when turning or changing lanes.

[0031] The above specific embodiments are merely an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
