Exhaust pipe decorative cover

Abstract

The invention provides an exhaust pipe decorative cover. According to the exhaust pipe decorative cover, on the premise that the matching reliability of an electroplating outer frame and an inner plate is guaranteed, the flanging of the electroplating outer frame is small in length, light in weight and low in cost. The exhaust pipe decorative cover is characterized in that a Y-direction positioning tongue piece and a clamping piece are arranged on the frame edge of the outer frame in the mode of protruding towards the inner plate, and the Y-direction positioning tongue piece is inserted into a positioning hole formed in the inner plate to form Y-direction positioning matching; and a square hole is formed in the clamping piece, a clamping body is arranged at the position, corresponding to the clamping piece, of the inner plate, the clamping body is matched with the square hole in a clamped mode, and a hollowed-out deformation hole is formed in the position, close to the clamping body, of the inner plate. Compared with a common double-layer U-shaped groove structure, a single-layer clamping body structure is adopted, the requirement for the longitudinal space is small, in addition, in order to keep the elasticity of the clamping body, the bottom of the clamping body is hollowed out, the elasticity of the clamping body is not kept by increasing the length of a cantilever commonly, the clamping position of the inner plate and the outer frame is effectively shortened, therefore, the flanging length of the outer frame is shortened, and the purposes of weight reduction and cost reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pipes, in particular to an exhaust pipe decorative cover. Background technique [0002] Automobile exhaust pipes are generally divided into two types: exposed and hidden. Among them, the exposed exhaust pipes are generally covered with decorative covers to increase the sense of refinement and sportiness of the vehicle. With the continuous improvement of the exterior shape and refined design of automobiles, more and more models choose to design exposed exhaust pipe decorative covers to highlight the overall sporty feeling of the vehicle, but it is limited by the space layout of the exhaust system and The platform of the exhaust pipe continues to meet the requirements, and some models choose to use the exhaust pipe decorative cover, that is, the exhaust pipe decorative cover is not directly facing the car exhaust pipe, but the interior of the decorative cover is a sealing structure, and t...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the exhaust pipe decoration cover mostly adopts the shape feature that the outer frame is a U-shaped electroplated frame, and the inner plate is a black leather-patterned part. Modeling structure, if the inner plate adopts the traditional U-shaped groove + cantilever clamping structure, in order to avoid the thickness of the mold at this place being too thin and resulting in insufficient strength, plus the double-layer material thickness of the U-shaped groove, the width of the U-shaped groove should not be too small ;In addition, in order to ensure the elasticity of the clamping structure, the length of the cantilever should not be short, which will cause the clamping surface of the outer frame and the inner plate to be relatively backward, resulting in longer flanges of the electroplated outer frame, thereby increasing the area of ​​the electroplated parts and Related product cost
