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

Embodiment Construction

[0016] For the convenience of explanation, the following problems are first defined: the direction of vehicle length is X direction, the direction of vehicle width is direction Y, and the direction of vehicle height is Z direction. The exhaust pipe decoration cover is installed at the rear of the car for the purpose of left-right symmetry and beauty. A fake trim cover where the exhaust pipes would be.

[0017] An exhaust pipe decorative cover, comprising an outer frame 10 and an inner panel 20, a Y-direction positioning tongue 11 and a snap-in piece 12 protrude from the edge of the outer frame 10 toward the inner panel 20, and the Y-direction positioning tongue 11 It is inserted into the positioning hole 21 provided on the inner plate 20 to form a Y-direction positioning fit. The snap-in piece 12 is provided with a square hole 121, and the inner plate 20 is provided with a snap-in body 22 at a position corresponding to the snap-in piece 12. The connecting body 22 is engaged wi...

Abstract

The invention provides an exhaust pipe decorative cover with small flanging length, small weight and low cost on the premise of ensuring the reliability of cooperation between the electroplating outer frame and the inner panel, and the edge of the outer frame faces the inner panel The protrusion is provided with a Y-direction positioning tongue and a clamping piece. The Y-direction positioning tongue is inserted into the positioning hole opened on the inner plate to form a Y-direction positioning fit. The clamping piece is provided with a square hole. The inner plate is connected with the clamping A clamping body is arranged at the corresponding position of the sheet, and the clamping body forms a clamping fit with the square hole, and a hollow deformation hole is opened on the inner plate adjacent to the clamping body. The single-layer snap-in body structure is adopted, which requires less vertical space than the common double-layer U-shaped groove structure. In addition, in order to maintain the elasticity of the snap-in body itself, the bottom of the snap-in body is hollowed out. The common method of increasing the length of the cantilever is not used to maintain the elasticity of the clamping body, which effectively shortens the clamping position between the inner panel and the outer frame, thereby shortening the length of the flange of the outer frame and achieving the purpose of reducing weight and cost .

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...
