In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figures 1 to 3As shown, an embodiment of the utility model provides a rear windshield water guide structure, comprising a rear windshield body 1, a water guide member 2, and a water guide groove 3 arranged on a vehicle body; the water guide member 2 comprises a drainage portion 21 connected to an end of the rear windshield body 1 close to a trunk lid 4; the water guide groove 3 is located below the drainage portion 21; an end of the drainage portion 21 away from the rear windshield body 1 extends downward into the water guide groove 3, so as to guide water on the rear windshield body 1 into the water guide groove 3. Among them, an end of the rear windshield body 1 close to the trunk lid 4 is connected to the drainage portion 21 of the water guide member 2, the drainage portion 21 is suspended above the water guide groove 3 on the vehicle body, and an end of the drainage portion 21 away from the rear windshield body 1 extends downward into the water guide groove 3. Understandably, the drainage portion 21 can be designed to be arc-shaped, so the drainage path of the drainage portion 21 is an arc-shaped drainage surface that bends downward from the rear windshield body 1. Therefore, after the water flows from the position of the rear windshield body 1 to the drainage portion 21, a Coanda effect (wall attachment effect) will be produced and the water will adhere to the arc-shaped drainage surface of the drainage portion 21, thereby deviating from the original flow direction toward the position of the sealing strip and changing to a tendency to flow along the convex arc-shaped drainage surface. In this way, the water will be drained into the water guide groove 3, and will not cross the sealing strip position at the upper edge of the trunk and impact into the trunk.

[0027] In the above-mentioned embodiment of the utility model, the drainage portion 21 of the water guide member 2 is installed at one end of the rear windshield body 1 close to the trunk lid 4, and the end of the drainage portion 21 away from the rear windshield body 1 extends downward to the water guide groove 3 arranged on the vehicle body. In this way, when the trunk lid 4 is opened, the water on the rear windshield body 1 will naturally adhere to the arc-shaped guide surface of the drainage portion 21 and flow downward, and finally be smoothly introduced into the water guide groove 3 without directly rushing into the trunk. The utility model changes the direction of water flow in a smaller space by designing the drainage portion 31 to prevent water from entering the trunk, thereby improving the overall waterproof performance of the vehicle. In addition, the utility model has a simple structure, good concealment, and good aesthetics.

[0028] In one embodiment, if Figures 2 to 3As shown, the drainage portion 21 includes a fixing element 211 connected to the rear windshield body 1, and an arc-shaped elastic piece 212 connected to the fixing element 211; one end of the arc-shaped elastic piece 212 away from the fixing element 211 extends downward to the water guide groove 3. The arc-shaped elastic piece 212 is used to abut against the trunk lid 4 when the trunk lid 4 is closed, and is used to guide the water on the rear windshield body 1 into the water guide groove 3 when the trunk lid 4 is opened. It can be understood that the fixing element 211 of the drainage portion 21 is connected to one end of the rear windshield body 1 close to the trunk lid 4, the arc-shaped elastic piece 212 of the drainage portion 21 is connected to the fixing element 211, and one end of the arc-shaped elastic piece 212 away from the fixing element 211 extends downward to the water guide groove 3. Furthermore, the fixing element 211 and the arc-shaped spring piece 212 can be made of elastic materials such as rubber, silicone or composite materials, as long as the fixing element 211 and the arc-shaped spring piece 212 have certain elasticity and deformation ability, and no specific limitation is made here. When the trunk lid 4 is closed, the arc-shaped spring piece 212 is compressed by the trunk lid 4 and deformed, thereby being able to cover the gap between the trunk lid 4 and the rear windshield body 1, and preventing water or dust impurities from entering the interior of the trunk; when the trunk lid 4 is opened, the arc-shaped spring piece 212 recovers to the uncompressed and deformed state due to the elasticity of its material itself. At this time, when water flows to the arc-shaped spring piece 212, the water flow can naturally adhere to the arc-shaped drainage surface on the arc-shaped spring piece 212 and flow downward, so as to be smoothly introduced into the water guide groove 3 on the vehicle body, effectively preventing water from entering the interior of the trunk from the rear windshield body 1.

[0029] In one embodiment, if Figure 2 and Figure 3 As shown, a mounting groove 5 is provided between the rear windshield body 1 and the vehicle body, and the fixing element 211 is installed in the mounting groove 5. It can be understood that the mounting groove 5 provided between the rear windshield body 1 and the vehicle body can be used to install the fixing element 211, and the fixing element 211 is inserted in the mounting groove 5 by interference fit, so that a tight connection is formed between the fixing element 211 and the mounting groove 5. Since the interference fit installation can generate a clamping force, the connection stability between the fixing element 211 and the mounting groove 5 can be strengthened to prevent the fixing element 211 from falling off due to the pressure of the trunk lid 4 when the trunk lid 4 is closed, and at the same time, water can be prevented from entering the trunk through the mounting groove 5.

[0030] In one embodiment, if Figure 2 and Figure 3As shown, the rear windshield water guide structure further includes a rear windshield rubber strip 6, which is installed in the installation slot 5 and is located at one end of the fixing element 211 away from the arc-shaped elastic sheet 212. It is understandable that the rear windshield rubber strip 6 is installed in the installation slot 5, and the rear windshield rubber strip 6 can fill the gap between the rear windshield body 1 and the vehicle body, and can play a sealing role during the driving process of the vehicle, reducing the impact damage of vibration to the windshield body and the vehicle body; and the rear windshield rubber strip 6 is arranged at one end of the fixing element 211 in the installation slot 5 away from the arc-shaped elastic sheet 212, which can play a role in fixing and limiting the fixing element 211, and enhance the firmness of the installation of the fixing element 211; it is understandable that the rear windshield rubber strip 6 and the fixing element 211 can be connected or not connected.

[0031] In one embodiment, if Figure 2 and Figure 3 As shown, the water guide 2 also includes a flexible connection part 22 arranged on the side of the drainage part 21 away from the trunk lid 4; the flexible connection part 22 is connected between the drainage part 21 and the inner wall of the water guide groove 3. It can be understood that the flexible connection part 22 is arranged between the drainage part 21 and the inner wall of the water guide groove 3, and the flexible connection part 22 can also be made of elastic materials such as rubber, silicone or composite materials, as long as the material of the flexible connection part 22 has a certain elasticity and deformation ability, and no specific limitation is made here. When the trunk lid 4 is opened, when water flows downward along the arc-shaped drainage surface of the drainage part 21, the water will generate downward pressure on the drainage part 21. At this time, the flexible connection part 22 (arc-shaped spring sheet 212) will also be slightly deformed by the pressure, so that the end of the drainage part 21 is further bent downward to increase the water flow speed, thereby achieving a faster and smooth drainage of water into the water guide groove 3. When the trunk lid 4 is closed, the drainage portion 21 will be subjected to the pressure of the trunk lid 4, thereby pushing the flexible connection portion 22 to deform to absorb and buffer the pressure. At the same time, it is also used to support the drainage portion 21 (arc-shaped spring piece 212) to prevent the drainage portion 21 from being damaged by colliding with the vehicle body due to excessive pressure; and the flexible connection portion 22 can also push the drainage portion 21 to abut against the trunk 4 under the action of its own elastic force when the water guide member 2 is pressed by the trunk lid 4, thereby ensuring the sealing performance of the gap between the trunk lid 4 and the rear windshield body 1 when the trunk lid 4 is closed.

[0032] In one embodiment, if Figure 2 As shown, one end of the flexible connection part 22 away from the drainage part 21 is bonded to the inner wall of the water guide groove 3; it can be understood that one end of the drainage part 21 is bonded to the inner wall of the water guide groove 3, which ensures the firmness of the connection between the flexible connection part 22 and the inner wall of the water guide groove 3, simplifies the installation of the flexible connection part 22, and reduces the installation difficulty and cost.

[0033] In one embodiment, the flexible connection part 22 and the drainage part 21 are an integrally formed structure. Further, the water guide 2 is an integrally formed structure. It can be understood that when the flexible connection part 22 and the drainage part 21 are an integrally formed structure, or the water guide 2 is an integrally formed structure, the connection between the flexible connection part 22 and the drainage part 21 (or between the various components of the water guide 2) is more secure, reducing the looseness caused by improper connection of the separate parts, thereby ensuring that when the drainage part 21 is subjected to pressure or vibration, the stability and reliability of the water guide 2 can be improved.

[0034] In one embodiment, if Figure 2 and Figure 3 As shown, at the connection point between the drainage portion 21 and the rear windshield body 1, the tangent of the drainage portion 21 is parallel to the rear windshield body 1. It can be understood that the curvature of the drainage portion 21 and the rear windshield body 1 at the connection point is continuous, that is, at the connection point, the curvature radius of the drainage portion 21 and the rear windshield body 1 are the same, so that when water flows through the connection point between the drainage portion 21 and the rear windshield body 1, the water can smoothly transition along the tangent direction of the drainage portion 21, which can reduce the turbulence and resistance caused by the curvature change, and improve the water flow guiding efficiency.

[0035] In one embodiment, if Figure 2 and Figure 3 As shown, the rear windshield water guide structure further includes a sealing strip 7 sealedly connected between the trunk lid 4 and the vehicle body; the sealing strip 7 and the water guide member 2 are arranged on opposite sides of the water guide groove 3. It can be understood that the sealing strip 7 is arranged between the trunk lid 4 and the vehicle body, which can effectively prevent water or other liquids from entering the trunk, and the sealing strip 7 and the water guide member 2 are arranged on opposite sides of the water guide groove 3 to form a double waterproof mechanism. First, the water guide member 2 is responsible for guiding the water flowing down from the rear windshield body 1 into the water guide groove 3, and second, the sealing strip 7 can prevent water from flowing into the vehicle from the gap between the trunk lid 4 and the vehicle body.

[0036] In one embodiment, if Figure 2 and Figure 3 As shown, the height of the highest point of the sealing strip 7 is greater than the height of the lowest point of the drainage portion 21. It can be understood that the height of the highest point of the sealing strip 7 and the height of the lowest point of the drainage portion 21 both refer to the height relative to the horizontal road surface when the vehicle is located on the water surface road surface; that is, when water is introduced into the water guide groove 3 through the drainage portion 21, the height of the lowest point of the drainage portion 21 (that is, the end of the drainage portion 21 away from the rear windshield body 1) from the horizontal road surface is always lower than the highest height of the sealing strip 7 from the horizontal road surface, so that the water will be smoothly diverted to the water guide groove 3, and will not go over the highest point of the sealing strip 7 and enter the luggage compartment.

[0037] The utility model also provides a vehicle, comprising the above-mentioned rear windshield water guide structure. In the vehicle in the above-mentioned embodiment of the utility model, the rear windshield water guide structure comprises a rear windshield body 1, a water guide member 2, and a water guide groove 3 arranged on the vehicle body; the water guide member 2 comprises a drainage portion 21 connected to the end of the rear windshield body 1 close to the trunk lid 4; the water guide groove 3 is located below the drainage portion 21; the drainage portion 21 extends downwardly from the end away from the rear windshield body 1 into the water guide groove 3, so as to guide the water on the rear windshield body 1 into the water guide groove 3. Among them, the end of the rear windshield body 1 close to the trunk lid 4 is connected to the drainage portion 21 of the water guide member 2, the drainage portion 21 is suspended above the water guide groove 3 on the vehicle body, and the drainage portion 21 extends downwardly from the end away from the rear windshield body 1 into the water guide groove 3.

[0038] In the vehicle of the above-mentioned embodiment of the utility model, the drainage portion 21 of the water guide member 2 is installed at one end of the rear windshield body 1 close to the trunk lid 4, and the drainage portion 21 extends downward from the end of the rear windshield body 1 to the water guide groove 3 arranged on the vehicle body. In this way, when the trunk lid 4 is opened, the water on the rear windshield body 1 will naturally adhere to the arc-shaped guide surface of the drainage portion 21 and flow downward, and finally be smoothly introduced into the water guide groove 3 without directly rushing into the trunk. The utility model changes the direction of water flow in a smaller space by designing the drainage portion 31 to prevent water from entering the trunk, thereby improving the overall waterproof performance of the vehicle. The utility model has a simple structure, good concealment, and good aesthetics.
