[0030] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of elements other than the listed elements and may also include additional elements not specifically listed.

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a wind resistance reduction wiper, including a wiper arm 1, a wiper blade 2 and a drive unit 3. The wiper blade 2 is installed on the wiper arm 1, and the drive unit 3 drives the wiper arm 1 to rotate, so that the wiper arm 1 drives the wiper blade 2 to clean the windshield of the car. A wind resistance reduction hole 11 is opened on the wiper arm 1.

[0032] In the wind resistance reduction wiper provided in this embodiment, by opening a resistance reduction hole 11 on the wiper arm 1, when the wiper arm 1 rotates under the drive of the drive unit 3 to clean the windshield of the car, the air flow can pass through the resistance reduction hole 11 on the wiper arm 1, thereby reducing the wind resistance experienced by the wiper arm 1, and then reducing the wind resistance experienced by the wiper as a whole, improving the wiper arm force of the wiper, making the cleaning effect of the wiper better, and reducing the power loss of the car.

[0033] Furthermore, the wiper arm 1 has a plurality of resistance reducing holes 11, which are sequentially distributed along the length of the wiper arm 1. This can enhance the wind resistance reduction effect of the wiper arm 1 and reduce the structural strength of the wiper arm 1.

[0034] At the same time, the resistance reduction hole 11 provided on the wiper arm 1 is a rectangular hole. The rectangular hole can have a larger length within the width limit of the wiper arm 1, thereby providing the wiper arm 1 with a larger ventilation area, thereby achieving a better wind resistance reduction effect.

[0035] Furthermore, if Figure 3 As shown, the wiper arm 1 includes a main body 12 and mounting portions 13 vertically mounted on opposite sides of the main body 12. The drag reduction holes 11 are formed in the main body 12. This allows airflow to pass through the drag reduction holes 11 without being blocked by other parts of the wiper arm 1, allowing airflow to pass more smoothly, thereby achieving a better wind resistance reduction effect.

[0036] like Figure 4As shown, the windage reduction wiper system includes two wiper arms 1 and two wiper blades 2. One wiper blade 2 is mounted on each wiper arm 1. The installation method of the wiper blades 2 and wiper arms 1 is currently a relatively mature technology and will not be described in detail here. A drive unit 3 drives the two wiper arms 1 to rotate synchronously. By driving the two wiper arms 1 with a single drive unit 3, the two wiper arms 1 can swing in unison and avoid interference during swinging.

[0037] like Figure 4 and Figure 5 As shown, the drive unit 3 includes a driving member 31, a rotating member 32, a first transmission member 33, and a first connecting member 34. The rotating member 32 has a fixed end 321 and a rotating end 322 opposite to each other. The driving member 31 drives the rotating member 32 to rotate about the fixed end 321. One end of the first transmission member 33 is pivotally connected to the rotating end 322 of the rotating member 32, so that the first transmission member 33 moves back and forth under the drive of the rotating member 32. The other end of the first transmission member 33 is pivotally connected to one of the wiper arms 1. The two ends of the first connecting member 34 are pivotally connected to the two wiper arms 1 respectively.

[0038] The driving member 31 drives the first transmission member 33 to move back and forth through the rotating member 32. The first transmission member 33 drives one of the wiper arms 1 to swing during the reciprocating movement. One of the wiper arms 1 drives the first connecting member 34 to move during the swinging process. Since the first connecting member 34 connects the two wiper arms 1, one of the wiper arms 1 drives the other wiper arm 1 to swing during the swinging process, so that the swinging of the two wiper arms 1 tends to be consistent.

[0039] Furthermore, if Figure 6 As shown in , the drive unit 3 further includes a mounting member 35, two second transmission members 36, and two second connecting members 37. The mounting member 35 has a first end 351 and a second end 352 opposite to each other. The mounting member 35 is provided with a first connecting hole and a second connecting hole at the first end 351 and the second end 352, respectively. The axial directions of the first connecting hole and the second connecting hole are perpendicular to the rotation direction of the wiper arm 1. The two second connecting members 37 are respectively inserted into the first connecting hole and the second connecting hole, and the two ends of the two second connecting members 37 are respectively connected to a wiper arm 1 and a second transmission member 36. One end of the first transmission member 33 is pivotally connected to the rotating member 32, and the other end of the first transmission member 33 is pivotally connected to one of the second transmission members 36. The two ends of the first connecting member 34 are respectively pivotally connected to the two second transmission members 36.

[0040] Since the windshield of the car is installed at an angle on the car, by adding two second transmission members 36, the first transmission member 33 and the wiper arm 1 do not need to be directly connected. Connecting through the second connecting member 37 can enable the end of the wiper arm 1 where the wiper blade 2 is not installed to maintain a certain distance from the windshield of the car, adapting to the inclined installation of the windshield of the car.

[0041] Specifically, the rotating member 32 has a relative fixed end 321 and a rotating end 322. The fixed end 321 of the rotating member 32 is fixedly connected to the driving member 31. The driving member 31 drives the rotating member 32 to rotate around the fixed end 321. An axial hole is provided on the rotating end 322 of the rotating member 32. The first transmission member 33 has opposite ends, and axial holes are provided at both ends of the first transmission member 33. The rotating end 322 of the rotating member 32 and one end of the first transmission member 33 are rotatably connected by passing a first connecting shaft 38 through their axial holes. When the driving member 31 drives the rotating member 32 to rotate, the rotating end 322 of the rotating member 32 drives the first transmission member 33 to move back and forth. The other end of the first transmission member 33 is rotatably connected to one of the second transmission members 36. The second transmission member 36 has a third end 361 and a fourth end 362 opposite to each other, and an axial hole is provided between the third end 361 and the fourth end 362, and a second connecting shaft 39 is passed through the axial hole at one end of the first transmission member 33 close to the second transmission member 36 and the axial hole between the third end 361 and the fourth end 362 of the second transmission member 36, so that the first transmission member 33 and the second transmission member 36 are connected. The third end 361 of the second transmission member 36 is fixedly connected to one end of the second connection member 37, and the wiper arm 1 is fixedly connected to the other end of the second connection member 37. When the rotating member 32 drives the first transmission member 33 to reciprocate, the first transmission member 33 drives the second transmission member 36 to reciprocate around the third end 361 of the second transmission member 36. When the third end 361 of the second transmission member 36 reciprocates, it drives the second connection member 37 to rotate back and forth, thereby driving the wiper arm 1 fixedly connected to the second connection member 37 to reciprocate. At the same time, the first connection member 34 has two opposing ends and an axial hole is defined at both ends. The axial hole at one end of the first connection member 34 is connected to the axial hole at the fourth end 362 of the second transmission member 36 via a third connecting shaft 40, thereby rotating the first connection member 34 and the second transmission member 36. The other end of the first connection member 34 is connected to the axial hole at the fourth end 362 of the other second transmission member 36 via the third connecting shaft 40, thereby rotating the first connection member 34 and the other second transmission member 36. In this way, when the second transmission member 36 moves back and forth under the rotation of the driving member 31 driving the rotating member 32, the second transmission member 36 drives the first connecting member 34 to move back and forth, so that the first connecting member 34 drives the other second transmission member 36 to move back and forth. The two second transmission members 36 are connected to the two wiper arms 1 in the same way. When one of the second transmission members 36 drives one of the wiper arms 1 to move back and forth, the other second transmission member 36 also drives the other wiper arm 1 to make the same reciprocating movement.

[0042] Exemplarily, the second connecting member 37 is a pin.

[0043] Exemplarily, the driving member 31 can be a motor, and the output end 311 of the motor is fixedly connected to the rotating member 32. The output end 311 of the motor drives the rotating member 32 to rotate during the rotation process. The rotating member 32 can be movably and fixedly connected to the first transmission member 33 through a pin shaft, so that the first transmission member 33 and the rotating member 32 rotate relative to each other at the pin shaft, thereby driving the first transmission member 33 to move back and forth.

[0044] This embodiment also provides a car, comprising the wind resistance reducing wiper as described above.

[0045] In summary, the wind resistance reduction wiper provided in this embodiment and the automobile having the same have a resistance reduction hole 11 opened on the wiper arm 1, so that the wind resistance overcome by the wiper arm 1 during swinging is reduced, thereby achieving the effect of reducing wind resistance and having a stronger wiper arm force.

[0046] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
