[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a wiper support structure, wherein a water trough 200 and a reinforcing plate 201 arranged along the width direction of the front cabin are arranged in the front cabin, the reinforcing plate 201 is fixedly arranged on the outer edge of the top of the water trough 200, and the reinforcing plate 201 is also provided with reinforcing ribs along its length direction to enhance the strength of the water trough 200.

[0035] The support structure is arranged in the front cabin to support the wiper, and the support structure includes a first bracket 300, a second bracket 400 and a third bracket 500 arranged in sequence, referring to Figure 1 The first bracket 300, the second bracket 400 and the third bracket 500 are arranged roughly along the width direction of the front cabin, and the first bracket 300, the second bracket 400 and the third bracket 500 are all provided with mounting points for fixed connection with the wiper.

[0036] It can be understood that there are multiple panel structures in the front cabin, so the first bracket 300, the second bracket 400 and the third bracket 500 are not strictly arranged on a straight line or a plane. The first bracket 300, the second bracket 400 and the third bracket 500 only need to ensure stable installation of the wiper.

[0037] Specifically, the reinforcing plate 201 and the front cabin cover plate are both fixedly connected to the first bracket 300, and the reinforcing plate 201 is arranged along the width direction of the front cabin. It can be understood that the reinforcing plate 201 is arranged roughly horizontally, and the front cabin cover plate is arranged on both sides of the front cabin, and the front cabin cover plate is arranged roughly vertically. The first bracket 300 is fixedly connected to the reinforcing plate 201 and the front cabin cover plate. Then the front cabin cover plate can at least provide X-direction support for the first bracket 300, and the reinforcing plate 201 can at least provide Z-direction support for the first bracket 300. The first bracket 300 is supported with strong force, and the first bracket 300 is limited to a certain extent, so it is not easy to shake, and thus the support effect for the wiper is stable. Furthermore, the front cabin cover plate is generally tilted toward the front of the vehicle, and the front cabin cover plate can at least provide X-direction support and Y-direction support for the first bracket 300. Refer to Figure 1 and Figure 2 In some embodiments, the reinforcing plate 201 has an inclined surface facing the cockpit, so that the reinforcing plate 201 can provide Z-direction support and Y-direction support for the first bracket 300. The reinforcing plate 201 and the front engine compartment cover provide X-direction support, Y-direction support and Z-direction support for the first bracket 300, which can further improve the fastening degree of the first bracket 300 set in the front engine compartment, thereby improving the supporting effect of the first bracket 300 on the wiper. At the same time, the reinforcing plate 201 and the front engine compartment cover jointly limit the first bracket 300 in the X-direction, Y-direction and Z-direction, which can reduce the vibration of the wiper during operation, causing the first bracket 300 to shake and generate noise, thereby improving the NVH performance of the vehicle.

[0038] The second bracket 400 is fixedly disposed on the front panel 100, and the third bracket 500 is fixedly disposed in the water channel 200. Figure 1It can be understood that the reinforcing plate 201 is arranged on the water flow channel 200 and is away from the side of the front panel 100, and the first bracket 300 is fixedly connected to the reinforcing plate 201, then the first bracket 300 and the second bracket 400 have different Z-direction heights, the first bracket 300 and / or the third bracket 500 and the second bracket 400 are located at different positions in the Y direction, and the first bracket 300, the second bracket 400 and the third bracket 500 arranged in sequence are located at different positions in the X direction, wherein the X direction, the Y direction and the Z direction starting from the same origin are the same. They are perpendicular to each other, and the X direction is parallel to the width direction of the front cabin, that is, in this embodiment, the installation points of the first bracket 300, the second bracket 400 and the third bracket 500 are not located on the same plane. When the wiper is installed on the supporting structure, the first bracket 300, the second bracket 400 and the third bracket 500 will limit the wiper in multiple directions to ensure the stability of the wiper during operation, reduce the amplitude and frequency of shaking, and thus reduce the noise of the wiper during operation, improve the NVH performance of the front cabin, and improve the comfort of the ride.

[0039] Reference Figure 2 and Figure 3 In some embodiments, the first bracket 300 includes a mounting main board 301 and a first mounting plate 302 and a second mounting plate 303 arranged on the periphery of the mounting main board 301. An angle is provided between the mounting main board 301 and the first mounting plate 302 and the second mounting plate 303, so that the shape of the first bracket 300 is irregular and fits the structural arrangement in the front cabin, and the first bracket 300 is not easy to shake. The first mounting plate 302 is provided with at least one first connection point connected to the reinforcing plate 201, and the second mounting plate 303 is provided with at least one second connection point connected to the front cabin sealing plate. The first connection point and the second connection point are located in different planes. So that the reinforcing plate 201 and the front cabin sealing plate provide multi-directional support for the first bracket 300. Both the first connection point and the second connection point can be through holes, and corresponding mounting holes can be provided at the positions corresponding to the reinforcing plate 201 and the front cabin sealing plate, and the installation of the first bracket 300 can be completed by bolts. In order to ensure the stability of the installation of the first bracket 300, the first mounting plate 302 can be provided with two through holes, and the second mounting plate 302 can be provided with a through hole. The axes of the three through holes are not in the same plane, thereby improving the installation firmness of the first bracket 300 and preventing the first bracket 300 from shaking.

[0040] Reference Figure 2 and Figure 3In some embodiments, the first bracket 300 is also provided with flanges on its periphery, the mounting main board 301 is plate-shaped, and flanges can be provided on the periphery of the mounting main board 301 and the outer sides of the first mounting plate 302 and / or the second support plate 600 to improve the strength of the first bracket 300 itself and provide stable support for the wiper. In some embodiments, the reinforcing plate 201 partially wraps the shock tower 700 and is connected to the shock tower 700, and the first bracket 300 is close to the connection between the water channel 200 and the reinforcing plate 201 to improve the dynamic stiffness of the first bracket, thereby reducing the noise of the wiper during operation.

[0041] Reference Figure 4 The second bracket 400 includes a first box-type main body 401 and a third mounting plate 402 and a fourth mounting plate 403 arranged on the peripheral side of the first box-type main body 401. The front panel 100 is provided with at least two step surfaces. The first mounting plate 302 is fixedly connected to one step surface, and the second mounting plate 303 is fixedly connected to the remaining step surfaces. It can be understood that the front panel 100 where the step surfaces are located has planes with different orientations. When the second bracket 400 is fixedly connected to the front panel 100, the front panel 100 can provide supporting forces in different directions for the second bracket 400. When the wiper is working, the direction of the force applied to the second bracket 400 is changeable. Therefore, the second bracket 400 in this embodiment has strong anti-deformation performance, and the second bracket 400 is not easy to shake, which can improve the NVH performance of the front cabin.

[0042] In some embodiments, the first box-type body 401 is in the shape of a triangular prism with high strength and stable structure. The side edges of the first box-type body 401 are parallel to the step surface. It can be understood that the first box-type body 401 has an installation surface facing the front cabin, and the installation point is set on the installation surface.

[0043] Considering that the dash panel 100 is arranged vertically, in some embodiments, the support structure further includes a second reinforcing plate 201, and the second reinforcing plate 201 and the second bracket 400 are respectively arranged on the inner side and the outer side of the dash panel 100, the inner side of the dash panel 100 is the side facing the cockpit, and the outer side is the side facing the front cabin, the second reinforcing plate 201 is fixedly connected to the second bracket 400, and the dash panel 100 is located between the second reinforcing plate 201 and the second bracket 400, that is, by adding the second reinforcing plate 201 to the inner side of the dash panel 100, the strength of the dash panel 100 where the second bracket 400 is installed is improved, thereby improving the support strength of the dash panel 100 to the second bracket 400, reducing the possibility of deformation caused by force at the installation of the second bracket 400, improving the stability of the wiper, and thereby improving the NVH performance of the front cabin. Further, a reinforcing rib is arranged in the middle of the second reinforcing plate 201 to improve the strength of the second reinforcing plate 201, and further improve the support strength of the dash panel 100 to the second bracket 400.

[0044] Reference Figure 1 In some embodiments, a boss 203 in the middle of the water flow trough 200 is provided with two support plates 600 on opposite sides of the boss 203 along the width direction of the front cabin. The top end of the support plate 600 is fixedly connected to the front windshield of the vehicle, and the bottom end of the support plate 600 is fixedly connected to the top surface of the boss 203. The two support plates 600 are used to improve the strength of the water flow trough 200. The third bracket 500 includes a second box-type main body 501 and a fifth mounting plate 502, a sixth mounting plate 503 and a seventh mounting plate 504 arranged on the side of the second box-type main body 501. The fifth mounting plate 502 and the sixth mounting plate 503 are both fixedly connected to the boss 203, and the seventh mounting plate 504 is fixedly connected to a support plate 600. It can be understood that when the support plate 600 is vertically arranged, the support plate 600 supports the third bracket 500 in the X direction and / or Y direction, and there is an angle between the seventh mounting plate 504 and the fifth mounting plate 502. It can be understood that the third bracket 500 has high strength and is not easy to deform. It is also restricted by the support plate 600 and the top surface of the boss 203. The third bracket 500 is also not easy to shake and generate noise due to the operation of the wiper.

[0045] The second box-type body 501 is in the shape of a triangular prism and has high stability. The second box-type body 501 is not easily deformed and has a strong support force for the wiper. The side edges of the second box-type body 501 are parallel to the top surface of the boss 203 so that the second box-type body 501 has an installation surface for installing the wiper.

[0046] The top surface of the boss 203 is provided with an air inlet 202, and two support plates 600 are respectively provided on opposite sides of the air inlet 202. The third mounting plate 402 is fixedly connected to a side of a support plate 600 facing away from the air inlet 202 to prevent the support plate 600 from blocking the wiper operation. At the same time, the air inlet 202 of the water trough 200 is set in the middle of the top surface of the boss 203 and is located between the two support plates 600. An air inlet pipe is arranged between the air inlet and the blower of the air conditioner. It can be understood that the air inlet end of the blower can be set at the top of the blower, and the air inlet pipe has no bends. At this time, the air inlet pipe is short and straight, and it is not easy to generate noise when the air is taken in, which can significantly improve the NVH performance of the vehicle. Furthermore, the air inlet pipe is short in length, easy to assemble and can save the layout space of the front cabin. At this time, the front panel 100 does not need to set a avoidance structure for the air inlet pipe. The front panel 100 can be formed in one piece to improve the integrity of the front panel 100 and improve its own strength, which is beneficial to the stable support of the wiper by the second bracket 400.

[0047] In this embodiment, the second bracket 400 and the third bracket 500 are both fixedly installed at their corresponding positions by welding.
