The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] See also Figures 1 to 10, shown is a windshield wiper device for an automobile in an embodiment of the present invention, comprising a mounting mechanism 10 arranged on a front door 14 of an automobile, a driving mechanism arranged on the mounting mechanism 10, and a windshield wiper mechanism connected to the driving mechanism, the windshield wiper mechanism comprising a first windshield wiper 15 acting on a main rearview mirror 11, a second windshield wiper 16 acting on an auxiliary rearview mirror 12, and a third windshield wiper 17 acting on a side window glass 13, the driving mechanism comprising a main power source, a first connecting rod assembly 20 connecting the main power source and the first windshield wiper 15, and a third connecting rod assembly 21 connecting the first connecting rod assembly 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 reciprocate 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, so as to avoid the door and the wiper from being conflicted 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 present invention 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 the present embodiment, the main power source is a first motor 50, 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 one 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 581 hinged to the first crank 58 The second crank 582 and the third crank 584 are arranged in parallel, and the first rotating shaft 585 is installed on the main rearview mirror 11. The middle part 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 whose two ends are rotatably connected to the first crank 581 and the second crank 582 respectively, and a second connecting rod 583 whose two ends are rotatably connected to the second crank 582 and the third crank 584 respectively. One 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] It can be understood that when it is necessary to make the first wiper 15 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 reciprocates up and down; 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 reciprocatingly 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 rainwater on the main rearview mirror 11. Its movement trajectory can be referred to. Figure 3-4 .

[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, one end of the second curved rod 34 away from the first triangular plate 33 is rotatably connected to the second wiper 16, and one 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, the second shaft 36 and the third connecting rod 32 are driven to rotate, and then the second driving rod 31 is driven to move up and down reciprocatingly through the third connecting rod 32. When the second driving rod 31 moves up and down reciprocatingly, the second curved rod 34 is driven to swing through the first triangular plate 33, and then the second curved rod 34 is driven to move back and forth vertically, so as to achieve the cleaning of rain water for the auxiliary rearview mirror 12. The 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 with 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 continuously, the third driving rod 46 on the back thereof 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, and 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. The motion trajectory can be referred to in 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 arranged at a non-axial position of the flywheel 74, a seventh rotating shaft 77 connected to the four-bar structure 76, and a driving plate 71 fixedly connected to the seventh rotating shaft 77, a pulley 72 is provided on the fourth driving rod 45, and the driving 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 arranged 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 reciprocate, thereby driving the four-bar linkage 76 to move, wherein the four-bar linkage 76 has a second triangular plate 761, and the second triangular plate 761 rotates When the cam 43 is pulled away from the cam 43, the push block 47 and the toggle rod 48 are driven to rotate through the eighth rotating shaft 70, so as to pull the spline shaft 44 toward a position away from the cam 43. The movement of the spline shaft 44 drives the limit block 41 and the fixing portion 451 to move together. At the same time, the four-link structure 76 also drives the drive plate 71 to rotate through the rotation of the seventh rotating shaft 77. The drive plate 71 squeezes the pulley 72 together with the fourth drive rod 45, so that the fourth drive rod 45 and the third wiper 17 move toward a direction away from the side window glass 13 to prevent the third wiper 17 from interfering with the driver. This design structure can make the fourth drive rod 45 no longer rotate while pushing the third wiper 17 away. Its movement trajectory can be referred to. Figure 7 to Figure 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 disposed 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 wiper arranged on the A-pillar in the prior art causing 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.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
