Description

Technical Field

[0001] This utility model belongs to the field of automotive body technology, specifically relating to a door drainage structure. Background Technology

[0002] With the development of the automotive industry, the requirements for automobiles are also getting higher and higher. Traditional car door drainage channels usually have drainage holes on the outer panel of the door, which are then covered by the lower door guard plate. When the amount of rainwater is too large or too much water enters the inside of the door during car washing, the rainwater or water sprayed during car washing will accumulate inside the door and cannot be drained in time. The excessive water will then invade other parts of the car door. On the irregular surface of the inner door panel where anti-corrosion measures are not in place, problems such as corrosion and rust may occur. Utility Model Content

[0003] The purpose of this invention is to provide a car door drainage structure that improves the drainage effect inside the car door.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vehicle door drainage structure includes an outer door panel, an inner door panel, and a lower guard plate assembly disposed at the lower part of the outer and inner door panels. The lower guard plate assembly includes an outer lower guard plate and an inner lower guard plate that are interlocked with each other. The inner lower guard plate includes a drainage plate that is horizontally placed in the middle of the inner lower guard plate. The drainage plate has an upper plate and a lower plate that are vertically arranged on its inner and outer edges in the vehicle width direction, respectively. The upper and lower edges of the upper and lower plates are interlocked with the outer lower guard plate. The drainage plate has a drainage groove with the groove opening facing upward and the groove length direction consistent with the vehicle length direction. A drainage hole is provided in the drainage groove near the upper plate. The drainage plate is inclined downward along the vehicle width direction towards the side where the drainage groove is located.

[0006] In the above solution, the inner panel of the lower guard plate is equipped with a drainage plate. The drainage plate has a drainage groove with the opening facing upward and the groove length direction consistent with the vehicle length direction. When the amount of rainwater is too large or when too much water enters the inside of the car door during the car wash, it will flow into the drainage groove to form a water storage area, thereby ensuring that the excessive water will not invade other parts of the car door and improve the drainage effect of the car door.

[0012] like Figures 1-5 The diagram shows a door drainage structure, including an outer door panel 10, an inner door panel 20, and a lower guard plate assembly 30 disposed below the outer door panel 10 and the inner door panel 20. The lower guard plate assembly 30 includes an outer lower guard plate 31 and an inner lower guard plate 32 that are interlocked with each other. The inner lower guard plate 32 includes a drainage plate 321 placed horizontally in the middle of the inner lower guard plate 32. The inner and outer edges of the drainage plate 321 in the vehicle width direction are respectively provided with an upper plate 322 and a lower plate 323 arranged vertically. The upper and lower edges of the upper plate 322 and the lower plate 323 are interlocked with the outer lower guard plate 31. The drainage plate 321 is provided with a drainage groove 324 with the groove opening facing upward and the groove length direction consistent with the vehicle length direction. A drainage hole 40 is provided in the drainage groove 324 near the upper plate 322. The drainage plate 321 is inclined downward along the vehicle width direction towards the side where the drainage groove 324 is located.

[0013] In the above solution, the lower guard plate assembly 30 is located at the lower part of the outer door panel 10 and the inner door panel 20. The lower guard plate outer panel 31 is connected to the outer door panel 10. The lower guard plate inner panel 32 is provided with a drainage plate 321 in the middle. The drainage plate 321 is inclined downward along the vehicle width direction towards the side where the drainage groove 324 is located. Therefore, the water flowing down through the outer door panel 10 and the inner door panel 20 is guided by the drainage plate 321 and flows out from the drainage hole 40. At the same time, the drainage plate 321 is provided with a drainage groove 324 with the groove opening facing upward and the groove length direction consistent with the vehicle length direction, which is used to receive the water flowing down through the outer door panel 10 and the inner door panel 20. When the water volume is large and the drainage hole 40 cannot directly drain the water quickly, the drainage groove 324 can collect the excess water flow and prevent excessive water flow from splashing and invading other parts of the car door.

[0014] To reduce the number of molds and assembly time, this solution uses a vertically arranged water-retaining dam 50 formed on the drainage plate 321. The water-retaining dam 50, the drainage plate 321, and the upper plate 322 form a drainage trough 324 with the opening facing upward and the length of the trough aligned with the length of the vehicle, thereby constraining and guiding excess water flow.

[0015] Preferably, the edge of the door outer panel 10 and the door inner panel 20 is placed at the opening or inside the drainage groove 324 to ensure that water flowing down from the door outer panel 10 and the door inner panel 20 can directly reach the drainage groove 324. At the same time, the edge of the door outer panel 10 and the door inner panel 20 extends into the groove of the drainage groove 324. The edge of the panel and the water-blocking dam 50 of the drainage groove 324 form a double-layer barrier, which constitutes a meandering water flow path and can effectively prevent water from splashing out.

[0016] Furthermore, the water barrier 50 is arranged obliquely inward along the width of the vehicle, and the drainage channel 324 forms an open channel. When water flows down from the edge of the outer door panel 10 and the inner door panel 20, the obliquely arranged water barrier 50 can not only hold more water, but also block the splashed water in the path of water splashing.

[0017] Furthermore, based on experimental analysis of water accumulation, the vertical height of the dam 50 is greater than 7mm, which provides a good water-blocking effect.

[0018] Furthermore, the outer panel 31 and the inner panel 32 of the lower guard plate are interlocked with each other. The outer panel 31 of the lower guard plate has an outward flange 311 along the side of the vehicle length direction, and the inner panel 32 of the lower guard plate has an inward flange 325 along the side of the vehicle length direction. The outward flange 311 and the inward flange 325 are interlocked.
