Description

Technical Field

[0001] The invention relates to the technical field of automobile body manufacturing, in particular to an anti-collision limiting device for automobile doors. Background Art

[0002] During the process of painting the empty shell of the car body, the car door needs to be kept in a normal closed state. The current common protective measure is to use tape to fix the car door to the door opening to prevent the car door from colliding with the door frame. However, this solution is not only inefficient, but also after the tape is removed, the car body will have adhesive residues that are difficult to handle, affecting the appearance of the car body. Summary of the invention

[0003] In view of the defects existing in the prior art, the purpose of the present invention is to provide an anti-collision limiter for automobile doors, which can select a corresponding number of anti-collision limiters according to needs, and install them at different positions of the door frame and the door to fix and limit them and prevent them from colliding with the door opening to damage the paint film. The device is simple and convenient to operate and can be easily promoted.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an anti-collision limit device for a car door, comprising at least two clamping parts, and a connecting part is arranged between each two adjacent clamping parts; at least one clamping part is used to clamp the stop edge of the door opening, and at least one clamping part is used to clamp the stop edge inside the door frame.

[0005] On the basis of the above technical solution, the clamping part comprises a U-shaped elastic clamping body, in which a frame is arranged; and a plurality of anti-dropping teeth are arranged on the inner side of the clamping mouth of the elastic clamping body.

[0006] On the basis of the above technical solution, the elastic clamping body is made of foam rubber, and the frame is made of steel strip, insulating wood or rubber plate.

[0007] On the basis of the above technical solution, the connecting portion is vertically or inclined.

[0008] On the basis of the above technical solution, the connecting portion includes at least one elastic body, the elastic body is connected to an adjacent elastic body or a clamping portion, and a through hole is arranged in the elastic body.

[0009] Based on the above technical solution, the elastic body is circular, regular hexagonal or polygonal.

[0010] On the basis of the above technical solution, the elastic body is made of foamed rubber.

[0011] On the basis of the above technical solution, the orientation of the bayonet of at least one clamping portion is opposite to the orientation of the bayonet of the remaining clamping portions.

[0012] The present invention also discloses an anti-collision limit device for a car door, comprising at least two clamping parts, and a connecting part is arranged between each two adjacent clamping parts; at least one clamping part is used to clamp the edge of the door, and at least one clamping part is used to clamp the edge of the stopper of the door opening or the edge of the stopper inside the door frame.

[0013] The beneficial effects of the present invention are:

[0014] The present invention can select a corresponding number of anti-collision limit devices according to needs, and install them at different positions of the door frame and the door to fix and limit them, which is simple and convenient to operate. Specifically, the inclination angle of the connection part of the anti-collision limit device is arbitrary, and the length is also arbitrary. The through hole in the elastic body will deform under force, which is suitable for different positions. In addition, multiple clamping parts can be set to clamp multiple positions to meet the limit size requirements. Therefore, the present invention can meet the paint film protection at the door opening of all mainstream automobile body paint painting processes at home and abroad.
