Embodiment Construction

[0021] The technical solution of the present invention will be further explained below according to the drawings and specific embodiments.

[0022] The overall design principle of the leakage blockage of the automobile door is to design according to the actual conditions of the leakage hole and the structure of the inner panel of the vehicle door. In this preferred embodiment, carry out the design of leakage plugging of the present invention according to the leakage hole of square automobile door. figure 1 Shown is a structural schematic diagram of the leakage and blockage of the automobile door in the embodiment of the present invention. from figure 1 It can be seen from the figure that the liquid leakage blockage includes a fixed structure 1 , a blockage baffle plate 2 , a suspension structure 3 , a blockage pad 4 and a clamping structure 5 .

[0023] Fixing structure 1 is the plugging fitting surface. Here, the blocking fitting surface is designed as two curved surfaces a...

Abstract

The invention discloses a leakage block, which belongs to the technical field of automobiles. The leakage block structure comprises a fixing structure, a blocking pad and a suspended structure, wherein the leakage block is integrally fixed to a structure where a leakage hole is positioned by the fixing structure; and the blocking pad is arranged on the suspended structure and is vertically arranged by covering the leakage hole. When no liquid leaks from the leakage hole, the blocking pad has a sealing effect on the leakage hole; and when liquid flows out from the leakage hole, a gap is produced between the blocking pad and the outer edge of the leakage hole under the hydraulic action, so that the liquid is discharged from the gap. The leakage block guarantees the drainage function of the leakage hole and meanwhile can be used for sealing the leakage hole in case of no liquid discharge to solve the problem of air leakage of the leakage hole, so that the noise, vibration and harshness performance of the structure for mounting the leakage hole can be improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a vehicle body structure, especially a device related to a liquid leakage hole. Background technique [0002] In the design of modern automobiles, there are leak holes on the car doors, back doors or trunk lids, etc. The leak holes play an important role in the leakage of electrophoresis and the discharge of rainwater. However, the existence of the leakage hole will cause the problem of air leakage, thereby reducing the noise, vibration and harshness performance (ie NVH performance) of the vehicle. In order to ensure the function of the liquid leakage hole to discharge liquid, it is necessary to ensure that the leakage hole is unblocked when there is liquid, and to eliminate or alleviate the problems of vehicle noise, vibration and low acoustic roughness caused by air leakage, it is necessary to use it when there is wind When it exists, ensure that the tunnel is not unblocked ...
