Buffer block assembly and connection structure of automobile trunk lid with compact arrangement

Abstract

The invention discloses a car trunk cover buffer block assembly compact in arrangement. The car trunk cover buffer block assembly comprises a buffer block support, a buffer body and a sealing gasket,wherein the buffer body is adjustably installed on the lower portion of the buffer block support, an included angle is formed between an installation part on the upper side of the buffer block supportand a buffer connecting part on the lower side of the buffer block support, a gasket installation hole and a support installation hole are horizontally formed in the upper portion of the buffer blocksupport, and one end of the sealing gasket is installed in the gasket installation hole in a protruding mode. The invention further comprises a connecting structure of the car trunk cover buffer block assembly compact in arrangement. The included angle is formed between the installation part on the upper side of the buffer block support and the buffer connecting part on the lower side of the buffer block support, when the upper portion of the buffer block support is installed on a car trunk cover and the buffer body is installed on the lower portion of the buffer block support, the installation surface of the buffer block support makes contact with a sloping internal plate of the trunk cover, and the buffering contact surface of the buffer body makes vertical contact with a rear gutter channel, so that the dimension of the buffer block assembly in the Y direction is compact, and the buffer block assembly is easy to arrange; the internal plate of the trunk cover is easily formed in a punching mode.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a buffer block assembly and a connection structure of a compact automobile trunk lid. Background technique [0002] During the closing process of the trunk of the car, a certain displacement will continue to be generated due to inertia after the trunk is closed. When the displacement reaches a certain level, the trunk lid, side panels, rear taillights and other environmental parts will be bumped or even damaged. Therefore, it is necessary to arrange buffer blocks on the left and right sides of the trunk lid. [0003] In order to ensure beautiful appearance and improve aerodynamic performance, the design surface difference between the trunk lid and the side wall of the body is small; in order to increase the volume of the trunk of the car and increase the entrance size of the trunk, it is necessary to control and reduce the size of the water tank Sectional size, wh...

Problems solved by technology

[0003] In order to ensure beautiful appearance and improve aerodynamic performance, the design surface difference between the trunk lid and the side wall of the body is small; in order to increase the volume of the trunk of the car and increase the entrance size of the trunk, it is necessary to control and reduce the size of the water tank Sectional size, while the buffer blocks on the left and right sides of the trunk lid need to be arranged in the water tank. If the cross-sectional size of the water tank is too small, it will make it difficult to arrange the buffer block. If the cross-sectional size is too large, it will encroach on the entrance size of the trunk lid; Due to the tired use of the trunk lid, the installation part of the buffer block is not strong enough, or the sealing performance is poor; in addition, the trunk lid and the side wall of the body have accumulated more assembly errors during a series of assembly processes, making the trunk lid Even if the buffer block is installed, it will not have enough buffering effect

[0004] The Chinese patent with the application number 200910196340.5 discloses a buffer block capable of adjusting the initial spring-up performance of the automobile door cover. are parallel to each other, if the buffer block is applied to the left and right sides of the trunk lid, it will occupy the Y-direction space of the water tank
