[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] Please refer to the following Figures 1 to 7 A door waterproofing system and a vehicle according to an embodiment of the present invention are described.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the vehicle door waterproof system according to the embodiment of the present invention comprises: a vehicle door 1, a corner window glass 2 and a water guide 3, the vehicle door 1 comprises an inner panel assembly 11 and an outer panel assembly 12, the inner panel assembly 11 is arranged on the inner side of the outer panel assembly 12, and a door lock installation position 1111 is arranged on the inner panel assembly 11. It can be understood that the inner and outer directions of the inner and outer panel assembly 11 and the outer and inner directions of the outer panel assembly 12 are consistent with the inner and outer directions of the vehicle door 1. The inner side of the vehicle door 1 is the side of the vehicle door adjacent to the cabin, and the outer side of the vehicle door 1 is the side of the vehicle door away from the cabin.

[0037] The corner window glass 2 is fixed between the inner panel assembly 11 and the outer panel assembly 12. The water guide 3 is provided at the lower end of the corner window glass 2 and extends along the length direction of the corner window glass 2, at least part of the water guide 3 extends toward the direction of the outer panel assembly 12, and the water guide 3 and the outer side of the corner window glass 2 define a water guide groove 32, the water guide groove 32 extends along the length direction of the corner window glass 2, and at least part of the water guide groove 32 is located above the door lock installation position 1111.

[0038] It can be understood that the up-down direction of the corner window glass 2 is consistent with the up-down direction of the vehicle, and the length direction of the corner window glass 2 is consistent with the front-rear direction of the vehicle.

[0039] According to the vehicle door waterproofing system of an embodiment of the present invention, since a water guide member 3 is provided at the lower end of the corner window glass 2 and extends toward the outer panel assembly 12, and at least part of the water guide groove 32 is located above the door lock installation position 1111, the water flow that penetrates into the vehicle door 1 from the corner window glass 2 can be discharged through the water guide member 3 to avoid the water flow dripping downward onto the door lock installation position 1111, thereby improving the waterproofing effect of the vehicle door 1.

[0040] Alternatively, if Figure 1 As shown, in the length direction of the water guide member 3, the front end of the water guide groove 32 is lower than the rear end of the water guide groove 32. It can be understood that the water flow from the vehicle window flows from the back to the front along the extension direction of the water guide groove 32 under the action of gravity, so that the water flow avoids the door lock installation position 1111 under the corner window glass 2, thereby effectively solving the water leakage problem of the door lock installation position 1111, and the structure is simple, reliable, and easy to implement.

[0041] Alternatively, if Figure 2 As shown, the water guide 3 has a lip 31, the lip 31 is elastic, the lip 31 and the outer side of the corner window glass 2 define a water guide groove 32, and the lip 31 elastically abuts against the outer panel assembly 12. Specifically, the outer panel assembly 12 includes a vehicle door outer panel 121 and an outer panel reinforcement plate 122, the outer panel reinforcement plate 122 is arranged on the inner side of the vehicle door outer panel 121, and the lip 31 elastically abuts against the outer panel reinforcement plate 122. The vehicle door waterproof system of the embodiment of the present invention can guide the water inside the outer panel reinforcement plate 122 to the water guide groove 32 by elastically abutting the lip 31 against the outer panel reinforcement plate 122, so as to avoid the problem of water dripping along the outer panel reinforcement plate 122 to the door lock installation position 1111, thereby further avoiding the probability of water leakage at the door lock installation position 1111.

[0042] It is understandable that if Figure 2 As shown, the water guide member 3 is wrapped around the lower edge of the corner window glass 2, and a water guide groove 32 with an angle less than 90 degrees is formed between the upper end surface of the lip 31 and the outer side surface of the corner window glass 2. The side of the lip 31 away from the corner window glass 2 is elastically abutted against the outer panel reinforcement plate 122, which can further guide the water flow that penetrates into the vehicle door 1 to avoid the problem of water leakage from the door lock installation position 1111.

[0043] In a specific embodiment, Figure 1As shown, the lip 31 includes a first section 311, a second section 312 and a transition section 313. The first section 311 is arranged at the front end of the second section 312. The transition section 313 is arranged between the first section 311 and the second section 312 and is smoothly connected to the first section 311 and the second section 312. The height of the first section 311 is lower than that of the second section 312. In the direction from the back to the front of the water guide 3, the heights of the first section 311 and the second section 312 are gradually reduced. It can be understood that the extension paths of the first section 311, the second section 312 and the transition section 313 are generally stepped. The first section 311 and the second section 312 gradually tilt downward in the direction from the back to the front. The rear end of the transition section 313 is connected to the front end of the second section 312, and the front end of the transition section 313 is connected to the rear end of the first section 311. Since the water guiding member 3 of the vehicle door waterproofing system of the embodiment of the present invention adopts a structural design with a low front and a high rear, the water flow is guided from the rear of the vehicle door 1 to the position in front of the door lock installation position 1111 of the vehicle door 1 under the action of gravity, and is discharged through the front end of the first section 311, thereby improving the water guiding effect of the water guiding member 3.

[0044] Alternatively, if Figure 2 As shown, an elastic sealing edge 34 is provided on the inner side of the water guide 3. For example, the sealing edge 34 may be a double-layer sealing structure. The sealing edge 34 extends toward the direction close to the inner panel assembly 11 and elastically abuts against the inner panel assembly 11, thereby preventing water or dust from entering the cavity in the vehicle door 1, thereby improving the sealing effect of the vehicle door 1.

[0045] Alternatively, if Figure 2 As shown, the door waterproof system further includes an outer water cut 4, which is disposed on the outer panel reinforcement plate 122 and abuts against the corner window glass 2. It can be understood that the outer water cut 4 is located above the water guide 3, and the outer water cut 4 can prevent most of the water on the window glass from penetrating into the door 1, thereby reducing the probability of water seepage at the door lock installation position 1111 of the door 1.

[0046] In some embodiments, Figure 1 and Figure 3 As shown, the vehicle door 1 further includes an upper guide rail 51 and a lower guide rail 52, which are arranged between the outer panel assembly 12 and the inner panel assembly 11, and both extend in the up-down direction of the vehicle door 1. The upper guide rail 51 is arranged at the upper end of the lower guide rail 52 and is arranged opposite to the lower guide rail 52, and there is an installation gap between the upper guide rail 51 and the lower guide rail 52. It can be understood that the vehicle door 1 is provided with a main window glass (not shown), which is located in front of the corner window glass 2, and the upper guide rail 51 is located between the main window glass and the corner window glass 2, and the upper guide rail 51 and the lower guide rail 52 can provide guidance for the up-down movement of the main window glass.

[0047] Since the upper guide rail 51 and the lower guide rail 52 are arranged relative to each other in the up and down directions, water on the main window glass or the corner window glass 2 can flow along the upper guide rail 51 to the lower guide rail 52, so that the water flow can be guided to avoid the water flow flowing to other positions in the vehicle door cavity, reducing the probability of water seepage at the door lock installation position 1111.

[0048] In addition, since a certain gap needs to be left when the upper guide rail 51 and the lower guide rail 52 are installed, interference between the upper guide rail 51 and the lower guide rail 52 is avoided to facilitate the assembly of the upper guide rail 51 and the lower guide rail 52. For example, the installation gap between the upper guide rail 51 and the lower guide rail 52 is greater than or equal to 4 mm and less than or equal to 8 mm. For example, the installation gap between the upper guide rail 51 and the lower guide rail 52 can be 4 mm, 6 mm or 8 mm. The inventors of the present application have found through experimental research that when the installation gap between the upper guide rail 51 and the lower guide rail 52 adopts the above range, it can not only ensure the smoothness of the water conduction of the upper guide rail 51 and the lower guide rail 52, but also facilitate the assembly of the upper guide rail 51 and the lower guide rail 52.

[0049] Alternatively, if Figure 3 As shown, a drainage channel 33 is provided at the front end of the water guide member 3, and the drainage channel 33 is communicated with the water guide groove 32, and the drainage channel 33 is arranged adjacent to the upper guide rail 51 or the lower guide rail 52. It can be understood that the water flow collected in the water guide groove 32 can flow to the front of the water guide groove 32 and be discharged through the drainage channel 33. Since the drainage channel 33 is arranged adjacent to the upper guide rail 51 or the lower guide rail 52, the water flow can flow downward along the guiding effect of the upper guide rail 51 and the lower guide rail 52, further reducing the probability of water seepage at the door lock installation position 1111.

[0050] Alternatively, if Figure 3 and Figure 4 As shown, the inner panel assembly 11 further includes a vehicle door inner panel 111 and an inner panel reinforcement plate 112, the inner panel reinforcement plate 112 is arranged between the vehicle door inner panel 111 and the outer panel assembly 12, the door lock installation position 1111 is arranged on the vehicle door inner panel 111, and the inner panel reinforcement plate 112 has a guide portion 1121, at least part of the guide portion 1121 is arranged above the door lock installation position 1111, and the guide portion 1121 extends downwardly and obliquely toward the direction close to the outer panel assembly 12. It can be understood that, since the door lock installation position 1111 is arranged below the guide portion 1121, and the door lock installation position 1111 is arranged on the vehicle door inner panel 111, by arranging the guide portion 1121 in a direction away from the vehicle door inner panel 111 and being spaced apart from the vehicle door inner panel 111, so that the guide portion 1121 is inclined downwardly and toward the direction close to the outer panel assembly 12, it can be prevented that the water flow on the inner panel reinforcement plate 112 directly drips onto the door lock installation position 1111.

[0051] In some embodiments, Figures 4 to 7As shown, the vehicle door waterproof system also includes a door lock assembly 6, which includes a door lock reinforcement plate 61 and a door lock body 62. The door lock reinforcement plate 61 is arranged at the door lock installation position 1111, and the door lock reinforcement plate 61 includes a reinforcement plate body 611 and a flange 612. The flange 612 is arranged at the upper end of the reinforcement plate body 611, and the flange 612 extends upwardly and obliquely in a direction away from the inner plate assembly 11. The door lock body 62 is installed on the reinforcement plate body 611. It can be understood that when water flows downward along the vehicle door inner plate 111 to the door lock assembly 6, the water can flow along the guide groove formed by the flange 612 and the vehicle door inner plate 111 to prevent the water from entering the door lock body 62, thereby improving the waterproof effect of the door lock body 62.

[0052] Alternatively, if Figure 6 As shown, there is a rubber coating layer 63 between the reinforcing plate body 611 and the inner plate assembly 11, the rubber coating layer 63 is arranged adjacent to the upper edge of the reinforcing plate body 611, and the outer peripheral contour of the rubber coating layer 63 is convex in the direction away from the door lock body 62. It can be understood that the outer peripheral contour of the rubber coating layer 63 can be an arc-shaped structure convex upward, or an inverted "V"-shaped structure, so that the water flow can be dispersed to both sides of the door lock body 62 through the guiding effect of the rubber coating layer 63, so as to prevent the water flow from entering the door lock body 62, thereby improving the waterproof effect of the door lock body 62.

[0053] Alternatively, if Figure 7 As shown, the door lock assembly 6 further includes a foam 64, which is disposed between the door lock body 62 and the door lock reinforcement plate 61, and at least part of the foam 64 is disposed on the upper edge of the door lock body 62 and the side edge of the door lock body 62. Therefore, the water flow can be dispersed to both sides of the door lock body 62 through the guiding effect of the foam 64 to prevent the water flow from entering the interior of the door lock body 62, thereby improving the waterproof effect of the door lock body 62.
