[0035] See also Figures 1 to 10, shown is a vehicle wiper device in an embodiment of the present utility model, comprising a mounting mechanism 10 provided on a front door 14 of a vehicle, a driving mechanism provided on the mounting mechanism 10, and a wiper mechanism connected to the driving mechanism, wherein the wiper mechanism comprises a first wiper 15 acting on a main rearview mirror 11, a second wiper 16 acting on an auxiliary rearview mirror 12, and a third wiper 17 acting on a side window glass 13, the driving mechanism comprises a main power source, a first connecting rod assembly 20 connecting the main power source and the first wiper 15, and a first connecting rod assembly 21 connecting the first connecting rod 22. The main power source generates electricity through the first link assembly 20 to drive the first wiper 15 to reciprocate at the main rearview mirror 11, the first link assembly 20 drives the second wiper 16 to reciprocate at the auxiliary rearview mirror 12 through the second link assembly 30, and the main power source generates electricity through the third link assembly 40 to drive the third wiper 17 to rotate back and forth at the side window glass 13.

[0036] It can be understood that the present invention provides a mounting mechanism 10 on the front door 14, and provides a driving mechanism and a wiper mechanism connected to the driving mechanism on the mounting mechanism 10. When the door is opened, the mounting mechanism 10, the main rearview mirror 11, and the auxiliary rearview mirror 12 are driven to rotate together, thereby avoiding the conflict between the door and the wiper caused by being provided on the A-pillar; at the same time, a first wiper 15 is provided on the main rearview mirror 11, a second wiper 16 is provided on the auxiliary rearview mirror 12, and a third wiper 17 is provided on the side window glass 13, and the main rearview mirror 11 is connected to the auxiliary rearview mirror 12 by the first connecting rod assembly 20. The power source is connected to the first wiper 15, the first wiper 15 and the second wiper 16 are connected through the second connecting rod assembly 30, and the main power source is connected to the third wiper 17 through the third connecting rod assembly 40. The three wipers can be moved synchronously through one power source and three connecting rod assemblies, which greatly improves the compactness of the structure, reduces the occupied space, and improves the aerodynamic coefficient; further, since the utility model also provides a wiper at the auxiliary rearview mirror 12, the blind spot can be checked even in rainy and snowy weather, thereby improving driving safety.

[0037] Specifically, in this embodiment, the main power source is a first motor 50, and the first connecting rod assembly 20 includes a reciprocating lifting structure connected to the first motor 50, a first driving rod 55 connected to the reciprocating lifting structure, a sleeve 57 installed on the main rearview mirror 11, and a first rotating rod 571 rotatably arranged in the sleeve 57, one end of the first rotating rod 571 is fixedly connected to a rotating rod 56, and the end of the rotating rod 56 away from the first rotating rod 571 is rotatably connected to the first driving rod 55, the first connecting rod assembly 20 also includes a parallel rotating structure 58 fixedly connected to the other end of the first rotating rod 571, and a first curved rod 59 hinged to the parallel rotating structure 58, the first curved rod 59 is rotatably connected to the first wiper 15; the parallel rotating structure 58 includes a first crank 581 fixedly connected to the first rotating rod 571, and a first crank 58 hinged to the first crank 58 A second crank 582 and a third crank 584 are arranged in parallel, and a first rotating shaft 585 is mounted on the main rearview mirror 11. The middle portion of the third crank 584 is rotatably connected to the first rotating shaft 585. The parallel rotating structure 58 also includes a first connecting rod 586 having two ends rotatably connected to the first crank 581 and the second crank 582, respectively, and a second connecting rod 583 having two ends rotatably connected to the second crank 582 and the third crank 584, respectively. The end of the third crank 584 away from the second connecting rod 583 is hinged to the first crank rod 59. The reciprocating lifting structure includes a worm 53 fixedly connected to the motor shaft of the first motor 50, a worm wheel 51 meshing with the worm 53, a second rotating rod 52 fixedly connected to the worm wheel 51, and a rotating block 54 fixedly connected to the second rotating rod 52. The rotating block 54 is rotatably connected to the first driving rod 55.

[0038] When the first wiper 15 is required to wipe the rain from the main rearview mirror 11, the first motor 50 can be started, the first motor 50 drives the worm 53 to rotate, the worm 53 drives the worm wheel 51 to rotate, and the second rotating rod 52 drives the rotating block 54 to rotate, so that the first driving rod 55 moves back and forth; because the sleeve 57 is fixed on the main rearview mirror 11, the up and down reciprocating movement of the first driving rod 55 will drive the first rotating rod 571 to rotate back and forth through the rotating rod 56, and then drive the parallel rotating structure 58 to move through the first rotating rod 571. Specifically, the first rotating rod 571 will drive the first crank 581, the second crank 582 and the third crank 584 to swing back and forth synchronously, and the third crank 584 will swing around the first rotating shaft 585 as the axis, and then drive the first wiper 15 to swing back and forth in parallel through the first crank rod 59, so as to achieve the cleaning of rain from the main rearview mirror 11. Its motion trajectory can be referred to. Figures 3 and 4 .

[0039] Furthermore, the second connecting rod assembly 30 includes a second rotating shaft 36 installed on the main rearview mirror 11, a third connecting rod 32 fixedly connected to the second rotating shaft 36, a second driving rod 31 hinged to the third connecting rod 32, a first triangular plate 33 rotatably connected to the second driving rod 31, and a second curved rod 34 rotatably connected to the first triangular plate 33, the end of the second curved rod 34 away from the first triangular plate 33 is rotatably connected to the second wiper 16, and the end of the second crank 582 away from the first connecting rod 586 is fixedly connected to the second rotating shaft 36.

[0040] It can be understood that when the second crank 582 rotates, it will drive the second rotating shaft 36 and the third connecting rod 32 to rotate, and then drive the second driving rod 31 to move up and down reciprocatingly through the third connecting rod 32. When the second driving rod 31 moves up and down reciprocatingly, it will drive the second curved rod 34 to swing through the first triangular plate 33, and then drive the second wiper 16 to move back and forth vertically through the second curved rod 34, thereby achieving the cleaning of rainwater from the auxiliary rearview mirror 12. Its motion trajectory can be referred to Figure 5 .

[0041] Furthermore, the third connecting rod assembly 40 includes a third rotating shaft 80 arranged at a non-axial position of the worm gear 51, a third driving rod 46 rotatably connected to the third rotating shaft 80, a fourth rotating shaft 81 rotatably connected to the end of the third driving rod 46 away from the third rotating shaft 80, a cam 43 rotatably connected to the fourth rotating shaft 81, a fifth rotating shaft 82 arranged at the axis of the cam 43, a limit block 41 embedded in the cam 43, and a spline shaft 44 fixedly connected to the limit block 41, and a fourth driving rod 45 rotatably connected to the third wiper 17, the spline shaft 44 passes through the cam 43 and the fifth rotating shaft 82 and is fixedly connected to the fourth driving rod 45, the fourth rotating shaft 81 is located at a non-axial position of the cam 43, and the cam 43 is provided with a limit groove 42 for the limit block 41 to be embedded.

[0042] It can be understood that while the worm gear 51 is rotating, the third driving rod 46 on its back side drives the cam 43 to swing back and forth, thereby driving the limit block 41 and the spline shaft 44 to swing back and forth. The reciprocating swing of the spline shaft 44 drives the third wiper 17 to rotate back and forth through the fourth driving rod 45, thereby achieving rainwater cleaning of the side window glass 13. Its motion trajectory can be referred to Figure 6 .

[0043] Furthermore, the automobile wiper device also includes a clutch mechanism, which includes a lifting assembly for moving the third wiper 17 away from the side window glass 13, and a plug-in assembly connected to the lifting assembly, and the plug-in assembly is used to move the limit block 41 away from the cam 43; the lifting assembly includes a second motor 73, a flywheel 74 connected to the second motor 73, a four-bar structure 76 provided at a non-axial position of the flywheel 74, a seventh rotating shaft 77 connected to the four-bar structure 76, and a drive plate 71 fixedly connected to the seventh rotating shaft 77, a pulley 72 is provided on the fourth driving rod 45, and the drive plate 71 is used to squeeze the pulley 72, the plug-in assembly includes an eighth rotating shaft 70 fixedly connected to the four-bar structure 76, a pushing block 47 fixedly connected to the eighth rotating shaft 70, and a toggle rod 48 provided on the pushing block 47, and a slot 49 for inserting the toggle rod 48 is recessed on the spline shaft 44.

[0044] It is understandable that when the driver wants to open the side window glass 13, the third wiper 17 will hit the driver's hand. Therefore, a clutch mechanism needs to be provided to ensure that the third wiper 17 can stop when the first wiper 15 and the second wiper 16 are working. Specifically, the fourth drive rod 45 includes a fixed portion 451 connected to the spline shaft 44, and a rotating portion 452 rotatably connected to the fixed portion 451. The rotating portion 452 is rotatably connected to the third wiper 17, and the second motor 73 is started, so that the second motor 73 drives the flywheel disc 74 to rotate back and forth, thereby driving the four-bar structure 76 to move, wherein the four-bar structure 76 has a second triangular plate 761, and the second triangular plate 761 rotates When the cam 43 is pulled away from the driving plate 71, the fourth driving rod 45 is moved, and the fourth driving rod 45 is moved together with the third wiper 17. This prevents the third wiper 17 from interfering with the driver. This design structure can prevent the fourth driving rod 45 from rotating when the third wiper 17 is pushed away. Figures 7 to 9 .

[0045] Furthermore, the first driving rod 55 includes a main rod 551 fixedly connected to the reciprocating lifting structure, a rotating sub-rod 552 rotatably arranged inside the main rod 551, and a universal joint 553 connecting the rotating sub-rod 552 and the rotating rod 56.

[0046] It is understandable that when encountering a situation of meeting other vehicles on a narrow road, the main rearview mirror 11 and the auxiliary rearview mirror 12 can be driven to rotate in three directions by rotating the sub-rod 552 and the universal joint 553 to cope with various emergencies.

[0047] Finally, the mounting mechanism 10 (ie, the protective shell) is put on each structure, and the mounting mechanism 10 is installed on the front door 14 .

[0048] In summary, the automobile wiper device in the above-mentioned embodiment of the present invention can avoid the problem in the prior art that the wiper arranged on the A-pillar causes the door to conflict with the wiper; and can improve the compactness of the structure and the aerodynamic coefficient; finally, a wiper is also arranged at the auxiliary rearview mirror, so that the blind spot can be checked even in rainy and snowy weather, thereby improving driving safety.
