Bumper block capable of adjusting initial bounce property of car door closure

Abstract

The invention relates to a bumper block capable of adjusting the initial bounce property of a car door closure, comprising a bumper block body and a bumper block mounting structure matched with the bumper block body, wherein the bumper block body is provided with a pipe casing substrate, the pipe casing substrate is provided with a regulation spring, one end of the pipe casing substrate is provided with a height regulation guide rod matched and connected with the regulation spring, and the other end of the pipe casing substrate is provided with a force regulation mechanism matched with the regulation spring. The bumper block provided by the invention can avoid the influence of a manufacturing tolerance. According to the variation of door closure quality, the bounce height and bounce forceof the door closure are regulated without any design change. Moreover, the product provided by the invention has good popularity, can adapt to the door closures with the requirement of different weights and different bounce weights and has small influence on door closing force. In addition, the bump block provided by the invention also has the beneficial effects of outstanding performance and thelike, is convenient for installation and regulation, and can be widely used in various car door closures.

Description

technical field [0001] The invention relates to a buffer block structure, in particular to a buffer block capable of adjusting the initial spring-up performance of an automobile door cover. Background technique [0002] In today's automotive technology requirements, after the car door is unlocked, it is required to be able to spring open to a certain height, so that the hand can be easily opened with force; when closing, it is required to be neither laborious nor to damage the surrounding parts. In order to complete or partially complete the above functional requirements, buffer blocks are usually designed and installed on the car door cover. The car door cover buffer block is generally installed on the door cover sheet metal parts, the specific position and structure are as follows figure 1 and Figure 2a shown. [0003] At present, the buffer block structure commonly used on the automobile door cover mainly has the following three structural forms: fixed type (such as ...

Problems solved by technology

[0005] However, the existing buffer block structure has a limited pop-up height for the door cover with heavy weight, especially without outward opening handle; although some existing buffer block structures can partially adjust the pop-up height, such as adjustable buffer The block can be screwed out to a certain length to assist the door cover to pop up, but it often increases the closing force, causing customers to complain

[0006] During the design process of the door cover, the change of the quality of the door cover, such as the quality change caused by the increase or decrease of the configuration, often needs to change the part design to ensure the appropriate pop-up height, and the cost will increase; at the same time, during use, as the sealing strip compresses Due to the attenuation of the reaction force and the influence of other factors, the pop-up height of the door cover will also decrease, which cannot be compensated, affecting the opening

[0007] The existing buffer block cannot meet the requirement of adjusting the pop-up height of the door cover, let alone meet the requirement of adjusting the pop-up height

These problems have greatly reduced the practical effect of the current door cover buffer block and the ability to share between systems
