Matching structure of door guard plate and inner triangular block and assembling process of matching structure

Abstract

The invention discloses a matching structure of a door protection plate and an inner triangular block and an assembling process of the matching structure. The matching structure comprises a door metalplate, a door guard plate, an inner triangular block and a screw, wherein a threaded hole is formed in the door metal plate, a cylindrical hole is formed in the middle of the upper end of the door guard, the screw penetrates through the cylindrical hole and is screwed in the threaded hole so as to enable the door guard plate to be tightly matched with the door metal plate, a cross-shaped positioning hole is formed beside the cylindrical hole, a first clamping groove and a second clamping groove are formed in the two sides of the upper end of the door guard plate, a third clamping groove is formed in the side edge of the door guard plate, a cross-shaped positioning pin is arranged in the middle of the lower end of the inner triangular block, a first inserting buckle and a second insertingbuckle are arranged on the two sides of the cross-shaped positioning pin respectively, a third inserting buckle is arranged on the side edge of the lower end of the inner triangular block, the inner triangular block is connected with the door guard plate in a matched mode, the cross-shaped positioning pin is inserted into the cross-shaped positioning hole for positioning, the first inserting buckle is inserted into the first clamping groove for clamping, the second inserting buckle is inserted into the second clamping groove for clamping, the third inserting buckle is inserted into the third clamping groove for clamping, and the position degree of the door guard plate in the Y direction is ensured; and the position degree of the inner triangular block in the X direction or the Z directionis ensured.

Description

technical field [0001] The invention belongs to the technical field of automobile design. Specifically, the invention relates to a matching structure of a door guard plate and an inner triangle block and an assembly process thereof. Background technique [0002] In normal production and assembly, the gap between the door guard plate of the car and the inner triangle block becomes larger due to the sinking of its own weight, forming a wedge-shaped gap, which makes it difficult to control the gap surface difference between the door guard plate of the car and the inner triangle block. [0003] In addition, the inner wall of the door guard plate of the car is matched with the side of the instrument panel, and the door guard plate of the car sinks, which makes it difficult to control the Y-direction position of the door guard plate. In severe cases, the inner wall of the door guard plate contacts the side of the instrument panel. Generate friction noise and affect ride comfort. ...

AI Technical Summary

Problems solved by technology

[0002] In normal production and assembly, the gap between the door guard plate of the car and the inner triangle block becomes larger due to the sinking of its own weight, forming a wedge-shaped gap, which makes it difficult to control the gap surface difference between the door guard plate of the car and the inner triangle block

[0003] In addition, the inner wall of the door guard plate of the car is matched with the side of the instrument panel, and the door guard plate of the car sinks, which makes it difficult to control the Y-direction position of the door guard plate. In severe cases, the inner wall of the door guard plate contacts the side of the instrument panel. Generate friction noise and affect ride comfort

[0004] In addition, often open and close the door, so that the inner triangle block is constantly squeezed by the sealing rubber strip on the door frame, which will cause the inner triangle block to move and loosen in the X or Z direction.
