[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] like Figure 1 and Figure 5 As shown, in one embodiment, at least one water flow hole 11 is provided on the wiper cover 1, and the water flow hole 11 penetrates the wiper cover 1 in the up and down directions; the inner surface of the water flow hole 11 has a drainage area 111; along the top-down direction, the drainage area 111 is inclined toward the water flow hole 11, and the drainage area 111 can guide the airflow entering the water flow hole 11 from top to bottom to the target object, so that the water molecules carried in the airflow collide with the target object and precipitate, thereby realizing water vapor separation and reducing the amount of suspended water in the airflow.

[0032] The drainage area 111 is a portion of the inner surface of the water flow hole 11 , and the drainage area 111 may be a flat surface or a curved surface.

[0033] In this embodiment, the up-down direction refers to the up-down direction of the vehicle, that is, the height direction of the vehicle; the front-back direction refers to the front-back direction of the vehicle, that is, the length direction of the vehicle; the left-right direction refers to the left-right direction of the vehicle, that is, the width direction of the vehicle. Figure 1 and Figure 5 In the directions shown, the up-down direction is parallel to the Z axis, the front-back direction is parallel to the X axis, and the left-right direction is parallel to the Y axis.

[0034] When the wiper cover 1 is applied to a vehicle, the wiper cover 1 is mounted on the vehicle body and is located between the front windshield and the hood. Figure 2 and Figure 3The vehicle also has a water receiving device 2, an air conditioner and a drain pipe. The water receiving device 2 has a water storage chamber 21, a drainage hole 22 and an exhaust hole 23; the water receiving device 2 is located below the wiper cover 1, and the water storage chamber 21 is opposite to the water flow hole 11. The air flow passes through the water flow hole 11 from top to bottom and enters the water storage chamber 21.

[0035] Furthermore, both the drain hole 22 and the exhaust hole 23 extend through the outer surface of the water receiving device 2 and communicate with the water chamber 21. The air intake duct of the air conditioner connects to the water chamber 21 through the exhaust hole 23, and the drain pipe connects to the water chamber 21 through the drain hole 22. During operation, air within the water chamber 21 can enter the air intake duct of the air conditioner, and water within the water chamber 21 can be discharged through the drain pipe. The configuration of the wiper cover 1 of this embodiment reduces the water content of the air within the water chamber 21 of the water receiving device, thereby effectively preventing rainwater and other substances from entering the air intake duct of the air conditioner.

[0036] Furthermore, the target object may be a wall of the water chamber 21, or a corresponding object independent of the water receiving device 2 and mounted within the water chamber 21 (in this case, the target object may be the guide plate 3 described below). Preferably, the target object is independent of the water receiving device 2, which facilitates the production and preparation of the water receiving device 2.

[0037] In one embodiment, the drainage area 111 extends from the upper surface of the wiper cover 1 to the lower surface of the wiper cover 1, which can improve the airflow guidance effect.

[0038] In one embodiment, the water flow hole 11 may be a square hole, a round hole, etc., and the cross section of the water flow hole 11 may be a regular shape or an irregular shape.

[0039] like Figure 4 and Figure 5 As shown, in one embodiment, the inner surface of the water flow hole 11 has four side surfaces, namely a first side surface 112, a second side surface 113, a third side surface 114, and a fourth side surface 115. The first side surface 112 and the second side surface 113 are spaced apart in the left-right direction, and the third side surface 114 and the fourth side surface 115 are spaced apart in the front-back direction. The first side surface 112 is located to the right of the second side surface 113, and the third side surface 114 is located behind the fourth side surface 115. Furthermore, the two ends of the first side surface 112 intersect with the third side surface 114 and the fourth side surface 115, respectively, and the two ends of the second side surface 113 intersect with the third side surface 114 and the fourth side surface 115, respectively.

[0040] In addition, at least one or a portion of at least one of the first side surface 112 , the second side surface 113 , the third side surface 114 , and the fourth side surface 115 may be the drainage area 111 .

[0041] like Figure 5 As shown, in one embodiment, the wiper cover 1 includes a cover body 12 and a drainage structure 13 connected in sequence, and the water flow hole 11 includes a first section hole and a second section hole connected in sequence; the first section hole is arranged on the cover body 12; the second section hole is arranged on the drainage structure 13; the drainage structure 13 is arranged below the cover body 12 and surrounds the outside of the first section hole.

[0042] This arrangement can reduce the thickness of the cover body 12 while ensuring the size of the water flow hole 11 in the up and down directions, thereby reducing the cost of the wiper cover 1.

[0043] The cover body 12 can be considered as the wiper cover 1 in the prior art, and the configuration of this embodiment can be considered as an additional provision of the drainage structure 13 on the basis of the existing wiper cover 1. Of course, when the drainage area 111 extends from the upper surface of the wiper cover 1 to the lower surface of the wiper cover 1, the configuration of this embodiment also makes certain modifications to the first section of the hole in the existing wiper cover 1 so that its inner surface can guide the airflow.

[0044] In addition, a water flow hole 11 may include a first section hole and a second section hole. When there are multiple water flow holes 11, each first section hole is set on the cover body 12, and there are multiple drainage structures 13, and one drainage structure 13 is provided with a second section hole.

[0045] In one embodiment, the inner surface of the water flow hole 11 includes the inner surface of the first hole section and the inner surface of the second hole section, wherein the inner surface of the first hole section and the inner surface of the second hole section may be smoothly transitioned.

[0046] In one embodiment, the cover body 12 and the drainage structure 13 may be an integrally formed structure. For example, the two may be integrally formed by injection molding.

[0047] In one embodiment, in the vertical direction, the surface of the cover body 12 facing away from the drainage structure 13 (i.e., the upper surface of the cover body 12) is the upper surface of the wiper cover 1, and the surface of the drainage structure 13 facing away from the cover body 12 (i.e., the lower surface of the drainage structure 13) is the lower surface of the wiper cover 1. When the drainage area 111 extends from the upper surface of the wiper cover 1 to the lower surface of the wiper cover 1, the drainage area 111 extends from the upper surface of the cover body 12 to the lower surface of the wiper cover 1 in the vertical direction.

[0048] In one embodiment, when the target object is independent of the water receiving device 2, it can be connected to the wiper cover 1. In this case, the wiper cover 1 has a connection area for connecting to the target object. After assembly, the target object is connected to the connection area. This helps to ensure the relative position of the drainage area 111 and the target object, which helps to improve the water vapor separation effect.

[0049] In one embodiment, the wiper cover 1 is provided with a plurality of hole groups spaced apart along the front-to-back direction; each hole group has at least one water flow hole 11; that is, the number of water flow holes 11 on the wiper cover 1 is multiple, and these water flow holes 11 are divided into multiple groups. Here, "multiple" means greater than or equal to two, and the term "multiple" has the same meaning in each embodiment and will not be repeated hereafter. Figure 4 In the example shown, there are three hole groups, each of which has a plurality of water flow holes 11 .

[0050] In addition, when a hole group includes a plurality of water flow holes 11 , the plurality of water flow holes 11 in the hole group are sequentially spaced apart along the left-right direction.

[0051] Furthermore, there are multiple connection zones, spaced apart along the front-to-back direction. Each hole group corresponds to a connection zone one-to-one; the drainage surface of each water flow hole 11 within a hole group is used to direct airflow to a target object connected to the corresponding connection zone. For ease of assembly, each connection zone can be connected to a single target object.

[0052] like Figure 5 As shown, in one embodiment, along the direction from back to front, the wiper cover 1 includes a first plate 14, a second plate 15, a third plate 16 and a fourth plate 17 connected in sequence; the second plate 15 is located above the first plate 14, the third plate 16 is located above the second plate 15, and the fourth plate 17 is located below the third plate 16; the first plate 14 and the third plate 16 are spaced apart in the up-down direction, and the second plate 15 and the fourth plate 17 are spaced apart in the front-to-back direction.

[0053] In addition, the first plate 14, the third plate 16 and the fourth plate 17 are all provided with water holes 11 and connection areas; the drainage area 111 of the water hole 11 on the first plate 14 is used to guide the airflow to the guide plate 3 connected to the first plate 14; the drainage area 111 of the water hole 11 on the third plate 16 is used to guide the airflow to the guide plate 3 connected to the third plate 16; the drainage area 111 of the water hole 11 on the fourth plate 17 is used to guide the airflow to the guide plate 3 connected to the fourth plate 17.

[0054] Among them, the water flow holes 11 arranged on the first plate 14 form a hole group, which corresponds to the connection area on the first plate 14; the water flow holes 11 arranged on the third plate 16 form a hole group, which corresponds to the connection area on the third plate 16; the water flow holes 11 arranged on the fourth plate 17 form a hole group, which corresponds to the connection area on the fourth plate 17.

[0055] In addition, the first plate 14 , the second plate 15 , the third plate 16 and the fourth plate 17 are all part of the cover body 12 , the first plate 14 , the third plate 16 and the fourth plate 17 are all provided with a first section hole, and the first plate 14 , the third plate 16 and the fourth plate 17 are all provided with a drainage structure 13 .

[0056] In one embodiment, the connection area and the drainage area 111 are spaced apart in the front-to-back direction. After assembly, the drainage area 111 and the target object are also spaced apart in the front-to-back direction.

[0057] like Figure 4 As shown, in one embodiment, each water flow hole 11 includes a first hole 11a, which is also a water flow hole 11. The inner surface of the first hole 11a has a drainage area 111. At this time, the first hole 11a and the connecting area are spaced apart in the front-to-back direction.

[0058] When the first hole 11a has a first side surface 112, a second side surface 113, a third side surface 114 and a fourth side surface 115, one of the four side surfaces is the drainage area 111. Figure 5 In the illustrated example, the water holes 11 provided on both the first plate 14 and the fourth plate 17 are first holes 11a. Furthermore, the drainage areas 111 of the water holes 11 on both the first plate 14 and the fourth plate 17 are located on the third side surface 114. The connection area on the first plate 14 is located in front of the water holes 11 on the first plate 14, and the connection area on the fourth plate 17 is located in front of the water holes 11 on the fourth plate 17.

[0059] like Figure 4 As shown, in one embodiment, each water flow hole 11 includes a second hole 11b, which is also a water flow hole 11. Two drainage areas 111 are provided on the inner surface of the second hole 11b. The two drainage areas 111 are located on the front and rear sides of the connecting area, and are spaced apart from the connecting area. This arrangement allows the airflow directed from the two drainage areas 111 to be separated into water vapor using the same target object.

[0060] exist Figure 5 In the example shown, the water flow holes 11 provided on the third plate 16 are second holes 11 b . In addition, the two drainage areas 111 of each water flow hole 11 on the third plate 16 are the third side surface 114 and the fourth side surface 115 .

[0061] like Figure 1 As shown, an embodiment of the utility model provides a cover assembly, including a guide plate 3 and the wiper cover 1 described in any one of the above embodiments; wherein, the guide plate 3 is the above-mentioned target object, the guide plate 3 is connected to the wiper cover 1, and protrudes downward from the wiper cover 1; the drainage area 111 can guide the airflow entering the water flow hole 11 from top to bottom to the guide plate 3.

[0062] In one embodiment, the wiper cover 1 and the guide plate 3 are detachably connected, so that when one of them is damaged, only the damaged one needs to be replaced, thereby reducing maintenance costs.

[0063] In one embodiment, after the vehicle is in use, guide plate 3 is positioned within water chamber 21 and spaced apart from water receiving device 2. This avoids or minimizes any adverse effects on airflow toward exhaust hole 23. During use, water droplets condensed on guide plate 3 flow along the guide plate to the bottom of water chamber 21. In other words, guide plate 3 guides the water droplets above it into water chamber 21.

[0064] The guide plate 3 and the water receiving device 2 are spaced apart from each other, which means that the guide plate 3 and the side wall of the water storage chamber 21 are spaced apart from each other, and the guide plate 3 and the bottom wall 28 of the water storage chamber 21 are spaced apart from each other.

[0065] In one embodiment, the guide plate 3 can be a flat plate structure. After assembly, the guide plate 3 is vertically arranged with the front-to-back direction being the thickness direction. The guide plate 3 is connected to the cover plate body 12 and / or the guide plate 3 is connected to the drainage structure 13.

[0066] like Figure 2 and Figure 3 As shown, the water chamber 21 has an overall rectangular structure. The sidewalls of the water chamber 21 include a first sidewall 24, a second sidewall 25, a third sidewall 26, and a fourth sidewall 27. The first sidewall 24 and the second sidewall 25 are spaced apart in the left-right direction, while the third sidewall 26 and the fourth sidewall 27 are spaced apart in the front-to-back direction. The first sidewall 24 is located to the right of the second sidewall 25, and the third sidewall 26 is located behind the fourth sidewall 27. The exhaust hole 23 is provided on the third sidewall 26 and penetrates the third sidewall 26 in the front-to-back direction.

[0067] In addition, the first side wall 24 , the second side wall 25 , the third side wall 26 and the fourth side wall 27 are all connected to the top of the bottom wall 28 . The drainage hole 22 is provided on the bottom wall 28 and passes through the bottom wall 28 in the up-down direction.

[0068] In one scenario, the air conditioner is located behind the water receiving device 2. To facilitate assembly, the exhaust hole 23 is provided on the rear side of the water receiving device 2, that is, the exhaust hole 23 is located on the rear side wall (i.e., the third side wall 26) of the water receiving device 2. After assembly, the exhaust hole 23 is located behind the guide plate 3 in the front-to-back direction.

[0069] Furthermore, the water flow holes 11 are located on the same side of the exhaust hole 23 in the left-right direction.

[0070] In one embodiment, when the inner surface of the water flow hole 11 has a first side surface 112 and a second side surface 113 that are spaced apart; in the left-right direction, the first side surface 112 is located between the second side surface 113 and the exhaust hole 23; at this time, along the top-down direction, the first side surface 112 is inclined toward the inside of the water flow hole 11, that is, along the top-down direction, the first side surface 112 gradually approaches the second side surface 113; the second side surface 113 is parallel to the up-down direction, or, along the top-down direction, the second side surface 113 is inclined toward the outside of the water flow hole 11, that is, along the top-down direction, the second side surface 113 gradually moves away from the first side surface 112.

[0071] At this time, the first side surface 112 can also play a role in guiding the airflow, and the guidance of the first side surface 112 can make the airflow flow in the direction away from the exhaust hole 23, so that the airflow can collide with the airflow flowing toward the exhaust hole 23, thereby facilitating water vapor separation. In addition, the second side surface 113 is vertical or tilted outward to avoid directing the airflow toward the exhaust hole 23, thereby facilitating water vapor separation.

[0072] like Figure 3 As shown, in one embodiment, when the exhaust hole 23 is located behind the guide plate 3, the guide plate 3 and the exhaust hole 23 are staggered in the front-to-back direction, so as to avoid or reduce adverse effects on the flow of air to the exhaust hole 23.

[0073] The staggered arrangement of the guide plate 3 and the exhaust hole 23 in the front-to-back direction may mean that, in an orthographic projection on a plane perpendicular to the front-to-back direction, the projection of the guide plate 3 and the projection of the exhaust hole 23 do not overlap.

[0074] It should be understood that the above-mentioned related settings can also be replaced by other methods, such as:

[0075] In other embodiments, the drainage area 111 may not extend to the upper surface of the wiper cover 1 , and / or the drainage area 111 may not extend to the lower surface of the wiper cover 1 .

[0076] In other embodiments, the guide plate 3 and the wiper cover 1 may also be an integrally formed structure.

[0077] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
