The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
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.
In an alternative embodiment, the first connecting portion and the second connecting portion are both in sleeve shapes, and become the first sleeve 2 and the second sleeve 4 respectively. The first connecting part is a first sleeve 2 of the elastic body 1, and the second connecting part is a second sleeve 4 of the fixing assembly. The first sleeve 2 is an outer sleeve, the second sleeve 4 is an inner sleeve, and the second sleeve 4 is positioned in the first sleeve 2.
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. The mounting portion may be a hole provided above the first sleeve 2 and the second sleeve 4. The fixing component is transversely arranged in the mounting part, namely, the base 3 and the elastic body 1 are fixedly mounted in the transverse direction perpendicular to the buffering direction, buffering of the buffering block is not participated, elastic force of the buffering direction is not provided, and the buffering value is convenient to control.

Therefore, the hardness of the buffer block elastic body 1 can be conveniently adjusted according to different vehicle door weights and requirements to adapt to different vehicle types.
As can be seen from fig. 1, the stroke of the elastic body 1 is also inconsistent in different positions of the four mounting portions of the fixing assembly, so that the provided elastic force value is also different, and therefore, the hardness of the elastic body 1 of the buffer block can be adjusted by adjusting the position of the fixing assembly, so as to adapt to different vehicle types; and meanwhile, the adjustment time of workers is also reduced. Different from the rotary elastic body 1 buffer block and the elastic buffer block with the pressure spring, the hardness of the elastic body 1 is visually adjusted and controllable, and the hardness of the elastic body 1 is difficult to control by two schemes in the prior art to adapt to the requirements of different vehicle doors.
As described above, the first connecting portion may rotate relative to the second connecting portion, and the fixing component may lock the first connecting portion at the mounting position of the first connecting portion. It follows that the installation of the utility model is also more convenient than in the prior art. When the buffer block is specifically installed, the installation base 3 of the buffer block is installed on the inner plate of the vehicle body or the door, and then the door is gently closed, so that the peripheral surface difference and the uniform gap are ensured; finally, the door is opened lightly, the elastic body 1 of the buffer block is rotated, and the first sleeve 2 is rotated, so that the fixed assembly is ensured to be clamped into the mounting part (hole). I.e. the first sleeve 2 is lockable by the securing assembly after rotation relative to the second sleeve 4.
Referring to fig. 1, the fixing component has a resilient function, for example, the fixing component includes a spring 6. The fixing assembly further includes a support member supporting the elastic member. The elastic piece is sleeved on the supporting piece and provides elasticity for the supporting piece. Friction force for supporting the elastic force of the elastic piece exists between the supporting piece and the mounting part.
In one embodiment, the support is a bayonet 5 and the resilient member is a spring 6. The elastic force of the spring 6 supports the bayonet lock 5, and the friction force between the bayonet lock 5 and the second sleeve 4 is used for supporting the elastic body 1, so that the self position of the elastic body is ensured. In the embodiment shown in fig. 2, the bayonet 5, the spring 6 are in the upper mounting position, and a right-hand cut of the first sleeve 2 is omitted in order to facilitate viewing of the drawing.
In order to reduce abnormal sound, the end part of the bayonet lock 5 is provided with plastic coating; the spring 6 is provided with a sheath 7, and grease is applied between the sheath 7 and the spring 6 to prevent abnormal sound. In other embodiments, preventing the head of the bayonet 5 from engaging the mounting portion (hole) includes, but is not limited to, over molding the tip of the bayonet 5, oiling the tip and hole, and the like.
In summary, the utility model aims to design a novel buffer block structure, and when the vehicle door is closed, the theoretical position of the elastic body 1 can be found according to the surface difference, so that the system tolerance can be effectively absorbed, and the adjustment time of workers can be reduced; the hardness of the buffer block elastic body 1 is adjusted to adapt to different vehicle types according to different door weights and requirements, and the stability of quality is ensured.
