The rotary elastic buffer block is repeatedly adjusted by workers as the adjusting area is not visible after the door is closed; the door can receive great impact when adjusting too high, closes the door, influences the durability of panel beating, in the door closed position, the door receives great counter-force all the time, can lead to opening the door and collapse and make a sound, influences customer's use experience. The buffer block can not prevent the effect of closing excessively when adjusting to be too low, and door panel beating and side wall have collision risk, can lead to the paint layer to break, and the panel beating also has the risk of panel beating fracture when serious. Because the buffer blocks cannot be effectively supported, the door can vibrate and produce abnormal sound on a bumpy or twisted road surface; the buffer blocks on two sides are unevenly adjusted, so that the surface difference and the gap between the door and the side wall can be influenced, and the appearance quality of the whole automobile is influenced.

The elastic buffer block with the pressure spring does not need to be adjusted manually, but the compression amount is always a variable because the system tolerance is required to be absorbed by the pressure spring; the torque of the pressure spring is too small to effectively support and buffer; the excessive torque of the compression spring can cause larger impact and sound quality problems.

The self-adjusting buffer block provided by the utility model plays a role in buffering the automobile door by means of the elasticity of the elastic body, and does not depend on the elasticity of the spring, so that the elastic force value (the interaction between the spring force and the elastic force in the prior art is difficult to be effectively vacant) can be effectively controlled, and the adjusting area of the self-adjusting buffer block is visible, so that the buffer block is convenient to adjust visually. The vehicle door comprises vehicle doors on two sides of a vehicle, a tail box door and a vehicle cover door of a vehicle head.

Specifically, referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of one direction of a new buffer block structure in an embodiment of the present utility model. Fig. 2 is a cross-sectional view of another direction of the novel buffer block structure in an embodiment of the present utility model. In one embodiment of the present utility model, a self-adjusting bumper is provided that includes two body portions, one being an elastomer 1 and the other being a mounting base 3. The elastic body 1 is used as a buffering main body, the installation base 3 is used for fixing the elastic body 1, the installation base 3 is usually installed on a sheet metal of a vehicle door, and the fixing mode of the installation base 3 includes but is not limited to interference fit, screwing, buckling and the like.

A fixing component is used between the elastic body 1 and the mounting base 3 and is used for fixedly connecting the elastic body 1 and the mounting base 3. In an embodiment, the elastic body 1 extends opposite to the mounting base 3 to form a part for fixing connection, the elastic body 1 includes a first connection part, and the mounting base 3 includes a second connection part adapted to the first connection part.

Further, the first connecting portion and the second connecting portion are respectively provided with a mounting portion for assembling the fixing assembly. Since the fixing component is located between the elastic body 1 and the mounting base 3, the fixing component can fix the elastic member and the mounting base 3 through the mounting portion.
