The waterproof performance of the whole vehicle will directly affect the comfort and safety of customers using the vehicle. Therefore, the waterproof design of automobiles is particularly important. As a high-incidence area of water leakage problems, how to ensure the sealing performance of the doors has become a key issue in automobile R & D, trial production and production.

[0003] Automobile waterproof plastic covers are a new trend in the sealing and waterproofing measures of passenger cars. They play an important role in water isolation and drainage inside the doors and are an important part of the customer experience. The internal structure of the doors is complex. The more functions are configured and the more wiring harnesses there are, and the internal structures of different automobile doors vary greatly. Therefore, it is necessary to design a suitable automobile waterproof plastic cover.

[0004] For large-area waterproof plastic covers, they usually do not have the function of fixing the wiring harness, resulting in some sections of the wiring harness inside the door being in a suspended state for a long time.

[0005] In addition, the existing waterproof plastic covers and the inner sheet metal of the doors have different coefficients of thermal expansion. When the external temperature rises, the body of the waterproof plastic cover will expand due to heat, and the resistance of the inner sheet metal of the door will cause the body of the waterproof cover to be squeezed and deformed, and in severe cases, the sealing ring may fail.

[0030] The following further elaborates on the present utility model in conjunction with specific embodiments, so that those skilled in the art can understand the present utility model more clearly.

[0031] It should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0032] Embodiment 1

[0033] Refer to Figure 1 、 2 、5, this embodiment provides a door waterproof system, including:

[0034] Inner door sheet metal 1, on which there is a window. The opening of the window can follow the waterproof principle. The upper half of the window is close to the direction of the outer door panel, and the lower half is far from the direction of the outer door panel, forming a step difference to reduce the risk of water flowing into the space between the inner door panel and the guard plate.

[0035] Waterproof cover plate 2, whose shape is correspondingly adapted to the window. The waterproof cover plate 2 is installed on the inner door sheet metal 1 by bolts. Specifically, the waterproof cover plate 2 protrudes with connecting parts around, and there are connection holes 10 on the connecting parts. There are mounting holes 9 at the edge of the inner door sheet metal 1 close to the window. By passing bolts through the connection holes 10 and the mounting holes 9 and locking them with nuts, the waterproof cover plate 2 can be locked and fixed to the inner door sheet metal 1. Moreover, the bolts are closely matched with the sheet metal, and both the dimensional error and the installation position error do not exceed 1 mm. In order to improve the stability of the installation process of the waterproof cover plate 2, a limiting structure 11 can also be provided at the edge of the inner door sheet metal 1 close to the window to play a certain limiting role on the waterproof cover plate 2, effectively improving the stability of the installation process of the waterproof cover plate 2.

[0036] An elastic sealing structure 3, whose shape is adapted to the window, is arranged between the waterproof cover plate 2 and the window so that the waterproof cover plate 2 and the window form a sealed fit. Optionally, the elastic sealing structure 3 is a sealing strip with a rectangular cross-section, which is formed by foaming, has a soft material and is easy to compress. The width dimension of the sealing strip can be designed according to actual needs, and the minimum value is 5 mm. The thickness of the sealing strip should be greater than the distance between the edge of the waterproof cover plate 2 and the edge of the window.

[0037] Reinforcing ribs 4 are arranged on the inner side surface of the waterproof cover plate 2 to improve the anti-deformation ability of the waterproof cover plate 2.

[0038] A wire harness fixing structure 5 is arranged on the reinforcing rib 4 to fix the wire harness inside the door, especially for vehicles with more complex functions, such as electric vehicles, etc. Optionally, the wire harness fixing structure 5 can be any structure capable of fixing the wire harness, such as a wire harness clip, a wire harness card or a wire harness tie.

[0039] Based on the above structure, the door waterproof system provided in this embodiment, by arranging the reinforcing ribs 4 on the inner side surface of the waterproof cover plate 2, can not only improve the strength of the waterproof cover plate 2, but also improve the anti-deformation ability of the waterproof cover plate 2. By arranging the wire harness fixing structure 5 to fix the wire harness inside the door, it is possible to avoid the wire harness shaking frequently during the movement of the vehicle, damaging the internal structure of the door, and even causing the wire harness to loosen and fall off. Moreover, arranging the wire harness fixing structure 5 on the reinforcing rib 4 can avoid directly arranging a connection structure on the waterproof cover plate 2 and damaging the integrity of the waterproof cover plate 2.

[0040] For example, the wire harness fixing structure 5 can be installed on the reinforcing rib 4 through bolts. Corresponding screw holes need to be reserved on the reinforcing rib 4. Installing through bolts is very convenient, has high installation efficiency and stable structure. Among them, a plurality of screw holes are arranged at intervals along the length direction of the reinforcing rib 4, so that the wire harness fixing structure 5 can be installed at a suitable position according to the actual situation, which is more flexible to use and has a wide application range. Moreover, there is no need to arrange connection structures such as screw holes on the waterproof cover plate 2, ensuring the integrity of the waterproof cover plate 2.

[0041] In this embodiment, the waterproof cover plate 2 can be a polypropylene (PP) plastic cover plate, which has excellent water resistance, corrosion resistance and processing performance.

[0042] The elastic sealing structure 3 can be an ethylene propylene diene monomer (EPDM) rubber sealing ring, which has excellent weather resistance, aging resistance and sealing performance, ensuring the long-term reliability of the waterproof system.

[0043] In some other embodiments, the reinforcing rib 4 can be a reinforcing rib with a regular hexagonal cross-section, and the side length is 23 mm. The side surface of the waterproof cover plate 2 is covered with the reinforcing ribs 4. This can comprehensively improve the anti-deformation ability and structural strength of the waterproof cover plate 2. Moreover, the regular hexagonal structure itself has extremely strong resistance to deformation and is very stable.

[0044] Embodiment 2

[0045] On the basis of Embodiment 1, two reinforcing ribs 4 are provided on the inner side surface of the waterproof cover plate 2. Refer to Figure 3-4 , the two reinforcing ribs 4 are arranged in parallel at intervals, and chutes are provided on the opposite inner walls of the two reinforcing ribs 4 so that the two reinforcing ribs 4 together form a slide rail, and a slider 6 is slidably fitted in the slide rail. The slider 6 is fixedly connected to the wire harness fixing structure 5 by bolts.

[0046] In this way, as the slider 6 slides in the slide rail, it can drive the wire harness fixing structure 5 to slide, and thus the position of the wire harness fixing structure 5 can be adjusted according to the actual situation.

[0047] Among them, a positioning screw hole is provided on the side wall of the slider 6, a positioning through hole 8 corresponding to the positioning screw hole is provided through the side wall of the reinforcing rib 4, and a positioning screw 7 is screwed in the positioning screw hole. The positioning screw 7 is inserted into the positioning through hole 8.

[0048] By passing one end of the positioning screw 7 through the positioning through hole 8 and extending it into the positioning screw hole for screwing and fixing, the slider 6 can be kept relatively fixed with respect to the reinforcing rib 4, and thus the wire harness fixing structure 5 can be kept relatively fixed with respect to the waterproof cover plate 2, and the position of the wire harness fixing structure 5 can be fixed. When the position needs to be adjusted, the positioning screw 7 can be removed. It is more flexible to use and has a wide range of applications.

[0049] In the present utility model, the mechanisms, components and parts for which no specific structures are described are existing structures that already exist in the prior art and can be directly purchased from the market.

[0050] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it cannot be understood as a limitation to the present utility model. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0051] The above are only the preferred embodiments of the present utility model and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
