Trough-glassy structure for lowering top-impacting sound of car door glass of car

Abstract

The invention discloses a trough-glassy structure for lowering top-impacting sound of car door glass of a car. The trough-glassy structure comprises a trough body and the car door glass, the car doorglass is connected to the inner side of the trough body in a clamped mode, a first lip and a second lip are arranged on the positions, on the lower part of the trough body, of the surfaces of the twosides of the car door glass, and a solid bubble is arranged at the top end of the trough body. According to the trough-glassy structure, a buffer lip or a buffer hollow bubble at the top end of the trough body is designed to be the solid bubble, and buffer ribs are additionally arranged on the outer surface of the bubble, so that the trough-glassy structure is different from the current structurethat the top section of a trough of a window frame is a U-shaped body, and lips of the car door glass are tightened by the buffer lip or the buffer bubble, the compression-resistant and impact-resistant capabilities of a buffer structure can be improved by the solid bubble, the top-impact sound during ascending of the car door glass is prevented or reduced, the riding comfort and the degree of satisfaction of a customer are improved, and the situation that in the long-time using process of a traditional trough, the buffer lip and the buffer bubble are crushed or deform and consequently cannotrecover to be in original states is avoided effectively.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a glass woolen structure for reducing the sound of the door glass hitting the top of the car. Background technique [0002] With the improvement of people's living standards, car travel is becoming more and more popular. Customer satisfaction The sound quality of car window glass lifting has become the focus of users' attention. The main function of the car's glass groove is to seal the gap between the door glass and the window frame. , waterproof and dustproof, airtight passenger compartment, improve NVH performance, and provide guidance for glass lift. [0003] At present, during the use of the wool structure of the window frame, the performance of the woolen groove continues to decay with the increase of time and the long-term impact and extrusion of the woolen groove when the glass is closed, the buffer lip and the buffer bubble are crushed or deformed. As a result, it ca...

Problems solved by technology

[0003] At present, during the use of the wool structure of the window frame, the performance of the woolen groove continues to decay with the increase of time and the long-term impact and extrusion of the woolen groove when the glass is closed, the buffer lip and the buffer bubble are crushed or deformed. As a result, it cannot return to the original state, the cushioning effect is lost, and there will be a loud impact sound when the glass rises. When the door glass is lowered, the trough is suddenly driven by the door glass after being squeezed by the glass. At the same time, the trough structure installation The tightness of the door sheet metal directly affects the effect of the groove, and a slight gap will easily lead to deformation of the groove
