Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to a door waterproofing system and a vehicle. Background Technology

[0002] As a major component of the vehicle body, car doors must possess excellent sealing performance to ensure a clean and comfortable interior environment. The door lock area is a dry zone and must not allow water leakage. However, in related technologies, the external water-cutting structure at the corner window location includes a sealing strip that abuts against the corner window glass to prevent water from entering the door interior. When the vehicle is driven in heavy rain or during a high-pressure wash, a large amount of water accumulates at the junction of the sealing strip and the corner window glass. This allows water to easily seep into the door interior and drip onto the door lock, eventually causing water to leak from the lock mounting location. This reduces the overall quality of the vehicle and negatively impacts the user experience. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose a door waterproofing system that can prevent water from entering the door lock installation location and improve the waterproofing effect of the door.

[0007] According to an embodiment of the present invention, the door waterproofing system has a water guide at the lower end of the corner window glass that extends toward the outer panel assembly, and at least part of the water guide channel is located above the door lock mounting position. As a result, water that seeps into the door from the corner window glass can be discharged through the water guide to prevent water from dripping down onto the door lock mounting position, thereby improving the waterproofing effect of the door.

[0008] In some embodiments, along the length of the water guide, the front end of the water guide channel is lower than the rear end of the water guide channel.

[0009] In some embodiments, the water guide has a lip that is elastic, the lip defining the water channel with the outer side of the corner window glass, and the lip abutting against the outer panel assembly.

[0012] In some embodiments, the door further includes an upper guide rail and a lower guide rail, which are disposed between the outer panel assembly and the inner panel assembly. Both the upper guide rail and the lower guide rail extend along the vertical direction of the door. The upper guide rail is disposed at the upper end of the lower guide rail and is arranged opposite to the lower guide rail. There is an installation gap between the upper guide rail and the lower guide rail.

[0013] In some embodiments, the installation gap between the upper guide rail and the lower guide rail is greater than or equal to 4 mm and less than or equal to 8 mm.

[0014] In some embodiments, the front end of the water guide is provided with a drainage channel, the drainage channel is connected to the water guide groove, and the drainage channel is arranged adjacent to the upper guide rail or the lower guide rail.

[0015] In some embodiments, the inner panel assembly further includes an inner door panel and an inner panel reinforcement plate, the inner panel reinforcement plate being disposed between the inner door panel and the outer panel assembly, the door lock mounting position being disposed on the inner door panel, the inner panel reinforcement plate having a guide portion, at least a portion of the guide portion being disposed above the door lock mounting position, and the guide portion extending downward at an angle toward the outer panel assembly.

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

[0035] The following is a reference appendix. Figures 1 to 7 A door waterproofing system and a vehicle according to embodiments of the present invention are described.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the vehicle door waterproofing system according to an embodiment of the present invention includes: a vehicle door 1, a corner window glass 2, and a water guide 3. The vehicle door 1 includes an inner panel assembly 11 and an outer panel assembly 12. The inner panel assembly 11 is disposed inside the outer panel assembly 12, and a door lock mounting position 1111 is provided on the inner panel assembly 11. It is understood that the inward and outward directions of the inner panel assembly 11 and the outer panel assembly 12 are consistent with the inward and outward directions of the vehicle door 1. The inner side of the vehicle door 1 is the side of the vehicle door adjacent to the passenger compartment, and the outer side of the vehicle door 1 is the side of the vehicle door away from the passenger compartment.

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

[0038] It is understandable that the vertical direction of the corner window glass 2 is consistent with the vertical direction of the vehicle, and the length direction of the corner window glass 2 is consistent with the front-to-back direction of the vehicle.

[0039] According to an embodiment of the present invention, the door waterproofing system has a water guide 3 at the lower end of the corner window glass 2 extending toward the outer panel assembly 12, and at least part of the water guide groove 32 is located above the door lock mounting position 1111. As a result, water that seeps into the door 1 from the corner window glass 2 can be discharged through the water guide 3 to prevent water from dripping down onto the door lock mounting position 1111, thereby improving the waterproofing effect of the door 1.

[0040] Optionally, such as Figure 1 As shown, along the length of the water guide 3, the front end of the water guide channel 32 is lower than the rear end of the water guide channel 32. It can be understood that water from the car window flows from back to front under the influence of gravity along the extension direction of the water guide channel 32, thus avoiding the door lock mounting position 1111 below the corner window glass 2. This effectively solves the leakage problem of the door lock mounting position 1111, resulting in a simple, reliable, and easily implemented structure.

[0041] Optionally, such as Figure 2 As shown, the water guide 3 has a lip 31, which is elastic. The lip 31 defines a water guide groove 32 with the outer side of the corner window glass 2, and the lip 31 elastically abuts against the outer panel assembly 12. Specifically, the outer panel assembly 12 includes a door outer panel 121 and an outer panel reinforcing plate 122. The outer panel reinforcing plate 122 is located on the inner side of the door outer panel 121, and the lip 31 elastically abuts against the outer panel reinforcing plate 122. The door waterproofing system of the embodiment of the present invention, by elastically abutting the lip 31 against the outer panel reinforcing plate 122, can guide water on the inner side of the outer panel reinforcing plate 122 to the water guide groove 32, thereby avoiding the problem of water dripping along the outer panel reinforcing plate 122 to the door lock mounting position 1111, and further reducing the probability of water leakage at the door lock mounting position 1111.

[0042] It is understandable that, such as Figure 2 As shown, the water guide 3 covers the lower edge of the corner window glass 2, and the upper end face of the lip 31 forms a water guide groove 32 with an angle of less than 90 degrees between it and the outer side of the corner window glass 2. The side of the lip 31 away from the corner window glass 2 elastically abuts against the outer panel reinforcement plate 122, which can further guide the water that seeps into the door 1 to avoid the problem of water leaking out from the door lock mounting position 1111.

[0043] In a specific embodiment, such as Figure 1As shown, the lip 31 includes a first segment 311, a second segment 312, and a transition segment 313. The first segment 311 is located at the front end of the second segment 312. The transition segment 313 is located between the first segment 311 and the second segment 312 and is smoothly connected to both segments. The height of the first segment 311 is lower than that of the second segment 312. Along the direction from back to front in the water guide 3, the heights of both the first segment 311 and the second segment 312 gradually decrease. It can be understood that the extension paths of the first segment 311, the second segment 312, and the transition segment 313 are generally stepped. The first segment 311 and the second segment 312 gradually slope downwards along the direction from back to front. The rear end of the transition segment 313 is connected to the front end of the second segment 312, and the front end of the transition segment 313 is connected to the rear end of the first segment 311. Because the water guide component 3 of the door waterproofing system in the embodiment of the present invention adopts a structure design that is low in the front and high in the rear, the water flow is guided from the rear of the door 1 to the position in front of the door lock mounting position 1111 under the action of gravity, and discharged through the front end of the first section 311, thereby improving the water guiding effect of the water guide component 3.

[0044] Optionally, such as Figure 2 As shown, the inner side of the water guide 3 is provided with an elastic sealing edge 34. For example, the sealing edge 34 can be a double-layer sealing structure. The sealing edge 34 extends toward the inner panel assembly 11 and elastically abuts against the inner panel assembly 11, thereby preventing water or dust from entering the cavity inside the door 1 and improving the sealing effect of the door 1.

[0045] Optionally, such as Figure 2 As shown, the door waterproofing system also includes an external water cutter 4, which is installed on the outer panel reinforcement plate 122 and abuts against the corner window glass 2. It can be understood that the external water cutter 4 is located above the water guide 3, and the external water cutter 4 can prevent most of the water on the window glass from seeping into the door 1, thereby reducing the probability of water seepage at the door lock mounting position 1111 of the door 1.

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

[0047] Since the upper guide rail 51 and the lower guide rail 52 are arranged opposite each other in the vertical direction, the water flow on the main window glass or corner window glass 2 can flow along the upper guide rail 51 to the lower guide rail 52, thereby guiding the water flow to avoid the water flow flowing to other positions in the door cavity and reducing the probability of water seepage at the door lock installation position 1111.

[0048] Furthermore, a certain gap needs to be maintained between the upper guide rail 51 and the lower guide rail 52 during installation to avoid interference and facilitate their assembly. 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. Alternatively, the installation gap between the upper guide rail 51 and the lower guide rail 52 can be 4 mm, 6 mm, or 8 mm. Through experimental research, the inventors of this application have discovered that when the installation gap between the upper guide rail 51 and the lower guide rail 52 is within the above-mentioned range, both the smooth water flow of the upper guide rail 51 and the lower guide rail 52 can be guaranteed, and the assembly of the upper guide rail 51 and the lower guide rail 52 can be facilitated.

[0049] Optionally, such as Figure 3 As shown, the front end of the water guide 3 is provided with a drainage channel 33, which is connected to the water guide trough 32. 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 collected in the water guide trough 32 can flow to the front of the water guide trough 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 can flow downward along the guiding action of the upper guide rail 51 and the lower guide rail 52, further reducing the probability of water leakage at the door lock mounting position 1111.

[0050] Optionally, such as Figure 3 and Figure 4 As shown, the inner panel assembly 11 also includes a door inner panel 111 and an inner panel reinforcing plate 112. The inner panel reinforcing plate 112 is disposed between the door inner panel 111 and the outer panel assembly 12. A door lock mounting position 1111 is disposed on the door inner panel 111. The inner panel reinforcing plate 112 has a guide portion 1121, at least a portion of which is located above the door lock mounting position 1111, and the guide portion 1121 extends downward at an angle toward the outer panel assembly 12. It can be understood that since the door lock mounting position 1111 is disposed below the guide portion 1121 and the door lock mounting position 1111 is disposed on the door inner panel 111, by arranging the guide portion 1121 in a direction away from and spaced apart from the door inner panel 111, so that the guide portion 1121 is inclined downward toward the outer panel assembly 12, water on the inner panel reinforcing plate 112 can be prevented from dripping directly onto the door lock mounting position 1111.

[0051] In some embodiments, such as Figures 4 to 7As shown, the door waterproofing system also includes a door lock assembly 6. The door lock assembly 6 includes a door lock reinforcing plate 61 and a door lock body 62. The door lock reinforcing plate 61 is located at the door lock mounting position 1111. The door lock reinforcing plate 61 includes a reinforcing plate body 611 and a flange 612. The flange 612 is located at the upper end of the reinforcing plate body 611 and extends upwards at an angle away from the inner panel assembly 11. The door lock body 62 is mounted on the reinforcing plate body 611. It can be understood that when water flows down along the inner door panel 111 to the door lock assembly 6, the water can flow along the guide channel formed by the flange 612 and the inner door panel 111, thus preventing water from entering the interior of the door lock body 62 and improving the waterproofing effect of the door lock body 62.

[0052] Optionally, such as Figure 6 As shown, an adhesive layer 63 is provided between the reinforcing plate body 611 and the inner plate assembly 11. The adhesive layer 63 is arranged adjacent to the upper edge of the reinforcing plate body 611, and the outer periphery of the adhesive layer 63 protrudes in a direction away from the door lock body 62. It can be understood that the outer periphery of the adhesive layer 63 can be an upwardly convex arc structure or an inverted "V" shape structure, so that water flow can be dispersed to both sides of the door lock body 62 through the guiding effect of the adhesive layer 63, so as to prevent water flow from entering the interior of the door lock body 62 and improve the waterproof effect of the door lock body 62.

[0053] Optionally, such as Figure 7 As shown, the door lock assembly 6 also includes foam 64, which is disposed between the door lock body 62 and the door lock reinforcing plate 61. At least a portion of the foam 64 is disposed along the upper edge and side edge of the door lock body 62. Therefore, water flow can be dispersed to both sides of the door lock body 62 by the guiding effect of the foam 64, thereby preventing water from entering the interior of the door lock body 62 and improving the waterproof effect of the door lock body 62.
