Problems solved by technology

In fact, for different vehicle models and different use positions of the buffer, it is often necessary to provide different buffer spacing to achieve a better buffer effect, which requires multiple sets of molds to produce buffers of different specifications, which significantly improves the Manufacturing cost and use cost

Embodiment Construction

[0038] The making and using of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention and do not limit the scope of the invention. The expression of the structural position of each component such as up, down, top, bottom, etc. in the description is not absolute, but relative. These directional expressions are appropriate when the various components are arranged as shown in the drawings, but when the positions of the various components in the drawings are changed, these directional expressions are also changed accordingly.

[0039]In the present invention, the longitudinal direction of the part refers to the direction along the length of the part, the transverse direction of the part refers to the direction perpendicular to the longitudinal direction of the part, and the circumferential direction of the part refers to the direction along the c...

Abstract

The invention provides a buffer device. The buffer device comprises a base which defines a containing cavity in the longitudinal direction, and the containing cavity is provided with a first joint part; the buffer pin is provided with a pin main body suitable for being inserted into the accommodating cavity, and the pin main body is provided with a second joint part; the locking bush and the base are fixed to each other; the pin main body can rotate in the accommodating cavity between an initial adjusting position and a locking position relative to the accommodating cavity; at the initial adjustment position, the first joint part is not jointed with the second joint part so as to allow the pin main body to move along the longitudinal direction; when the pin main body leaves the initial adjustment position and rotates to the locking position, the first joint part is jointed with the second joint part and drives the pin main body to move in the longitudinal direction to deviate from the base; at the locking position, the pin main body is locked by the locking bushing; the locking bushing includes a first locking portion positionable in at least two circumferential orientations relative to the receiving cavity to lock the pin body in at least two locking positions. The buffering device allows the buffering distance to be adjusted according to actual application requirements.

Description

technical field [0001] The present invention generally relates to the technical field of buffer devices, in particular to adjustable buffer devices. Background technique [0002] Usually, door components such as the trunk door, hood, and door of a vehicle form a small gap between the vehicle body and the vehicle body when they are closed, resulting in: When the vehicle is running, the door component repeatedly collides with the vehicle body due to vibration and bumps to generate noise Abnormal noise affects user experience. In order to avoid the noise caused by these gaps, bumpers are usually installed on the car body. [0003] Typically, the bumper has an abutment surface adapted to abut against the door component to provide cushioning. In the installation process of the buffer, usually, the abutment surface of the buffer is pushed by normally closing the door part, so that the abutment surface of the buffer is at the reference position, and then the abutment surface is f...
