Description

Technical Field

[0001] This utility model relates to components of automotive door module window regulators, and more particularly to a door module base plate with a waterproof structure. Background Technology

[0002] As the automotive industry moves towards lightweighting, modularization, integration, and intelligence, traditional window regulators have evolved into integrated door module regulators. Their lightweight, integrated, and comfortable features have been widely praised by customers and the market. However, their waterproofing and installation point strength have consistently been criticized by major OEMs and door module manufacturers, with frequent complaints about door leaks. The reason for these leaks in previous door modules was primarily due to the lack of waterproofing or water-draining structures in the pre-embedded nut holes, anti-collision sensor mounting locations, and door wiring harness mounting locations on the base plate. Figure 6 As shown, the anti-collision sensor mounting hole 2, the pre-embedded nut mounting hole 3, and the wiring harness mounting hole 4 on the door module base plate 1 lack waterproof or water-draining structures. This causes rainwater in the wet area of ​​the door to accumulate around the holes, accelerating the corrosion of the metal screws. If too much rainwater accumulates or the rainwater flow is large, it will enter the dry area of ​​the door, causing water to enter the vehicle interior. To avoid the defects of water leakage and insufficient rigidity of the door module base plate mounting holes, a waterproof system and reinforcement structure need to be designed for the door module base plate. Summary of the Invention

[0003] This utility model provides a door module base plate with a waterproof structure to solve the problems of water leakage from the mounting holes and insufficient installation strength of current door module base plates.

[0004] The technical solution adopted by this utility model is that there are anti-collision sensor mounting holes, pre-embedded nut mounting holes and wire harness mounting holes on the door base plate. A platform hole higher than the door base plate is added at the pre-embedded nut mounting hole, and reinforcing ribs are added around the pre-embedded nut mounting hole. A rainwater guide plate is set at the wire harness mounting hole, and a waterproof baffle is set at the anti-collision sensor mounting hole.

[0005] The inner wall of the platform hole opens outward, and the angle α between the outer wall and the substrate is greater than 90 degrees.

[0006] The waterproof baffle is semi-circular.

[0007] The advantages of this utility model are its novel structure. By adding a waterproof structure, rainwater is prevented from flowing through the pre-embedded nut mounting holes, wiring harness mounting holes, and anti-collision sensor mounting holes, thus preventing rainwater from accumulating and entering the dry area of ​​the door, thereby improving the overall waterproof capability of the door module. Rainwater cannot accumulate at the pre-embedded nut mounting holes, making the screws and nuts less prone to corrosion, thereby improving the overall corrosion resistance of the door module. Due to the addition of a reinforcing rib structure, the Y-direction strength of the door module is increased, and the stiffness at the mounting holes is increased by 8-10%.

Detailed Implementation

[0009] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0010] like Figure 1 , 2 As shown in Figures 3, 4, and 5, the door base plate 1 has anti-collision sensor mounting holes 2, pre-embedded nut mounting holes 3, and wiring harness mounting holes 4. A platform hole 5, higher than the door base plate 1, is added at the pre-embedded nut mounting hole 3, and reinforcing ribs 6 are added around the pre-embedded nut mounting hole 3. A rainwater guide plate 7 is installed at the wiring harness mounting hole 4, and a waterproof baffle 8 is installed at the anti-collision sensor mounting hole 2. These measures prevent rainwater from flowing through the mounting holes and entering the dry cavity of the door.

[0011] like Figure 3 As shown, the inner wall 501 of the platform hole 5 opens outward, and the angle α between the outer wall 502 and the substrate is greater than 90 degrees, to prevent water from flowing along the door substrate into the pre-embedded nut 9, and to avoid water accumulating at that place or flowing into the vehicle.

[0012] like Figure 4 As shown, the waterproof baffle 8 is semi-circular.

[0013] Working principle By adding platform holes 5 to the pre-embedded nut mounting holes, setting rainwater guide plates 7 to the wiring harness mounting holes, and setting waterproof baffles 8 at the anti-collision sensor mounting holes, rainwater will not accumulate and enter the dry area of ​​the door, thus improving the overall waterproof capability of the door module. Rainwater cannot accumulate at the pre-embedded nut locations, and screws and nuts are less prone to corrosion, thus improving the overall corrosion resistance of the door module. The reinforcing rib structure increases the Y-axis strength of the door module, increasing the stiffness at the pre-embedded nut locations from 102 N / mm to 112 N / mm.

[0014] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the scope of protection of the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, any equivalent substitutions or modifications made by those skilled in the art based on the technical solution and the inventive concept of the present invention within the scope of the technical concept disclosed in the present invention shall all fall within the scope of protection of the present invention.

[0015] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. For example, reinforcing ribs can be added at the anti-collision sensor mounting hole and the wire harness mounting hole according to the strength requirements. Therefore, in order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
