Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive decorative exhaust tip. Background Technology

[0002] A car exhaust tip, also known as an exhaust pipe sleeve, is a component installed at the end of the original exhaust system. It serves a decorative and aesthetic purpose for the car. Some car exhaust tips also have other functions, such as preventing the exhaust pipe from deforming, turbulence, and changing the exhaust sound. Some car exhaust tips can also reduce the noise emitted by the exhaust pipe to a certain extent and make the sound slightly softer and more pleasant.

[0003] For example, Chinese patent application number 202222034928.4 discloses a detachable and assembleable automotive tailpipe, including a housing, an exhaust pipe on the back of the housing, a locking bolt at the connection between the housing and the exhaust pipe, and a tailpipe trim piece at the end of the housing away from the exhaust pipe. This detachable and assembleable automotive tailpipe includes a housing and a tailpipe trim piece. By aligning the two connecting blocks on the tailpipe trim piece with the first connecting block and the first connecting block, and inserting them into the first connecting slot and the second connecting slot, a ring-shaped step can be positioned and installed with the tailpipe trim piece. Simultaneously, the locking bolt, threaded hole one, and threaded hole two can be used to install the tailpipe trim piece inside the housing. Furthermore, through modular design, the housing and tailpipe trim piece can be quickly disassembled and positioned for installation. The housing and tailpipe trim piece can be processed together or separately, presenting different visual effects and further enhancing aesthetics.

[0004] Those skilled in the art desire to design an exhaust tip that serves a decorative and aesthetic purpose for automobiles, based on existing technologies. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a decorative exhaust tip for automobiles that serves both decorative and aesthetic purposes.

[0006] To achieve the above objectives, this utility model provides a decorative exhaust tip for automobiles, comprising an outer shell, a main shell, a connecting pipe, a connecting piece, and a locking structure. The outer shell includes an isosceles trapezoidal shell of a certain length. The main shell includes an irregularly shaped inner shell, one end of which is circular and the other end is an isosceles trapezoid. The circular end radiates outwards in a trumpet shape towards the other end, gradually transforming into an isosceles trapezoid. The outer shell is disposed outside the main shell. One end of the outer shell is fixedly connected to one end of the isosceles trapezoid of the irregularly shaped inner shell through a connecting piece. The circular end of the irregularly shaped inner shell is connected to the connecting pipe. The other end of the connecting pipe is installed on the automobile exhaust pipe. The connecting pipe is fixed to the automobile exhaust pipe through the locking structure.

[0007] Furthermore, the locking structure includes a through mounting internal thread hole located on the side of the connecting pipe near the end of the vehicle's exhaust pipe, and a fixing bolt is screwed into the mounting internal thread hole.

[0008] Preferably, the number of mounting internal threaded holes is one to three.

[0009] Furthermore, the outer shell, main shell, connecting pipe, and connecting piece are made of stainless steel.

[0010] Preferably, the outer shell and the main shell are bluing treated.

[0011] Furthermore, the outer shell, main shell, connecting pipe, and connecting piece are made of galvanized iron.

[0012] Furthermore, the outer contour of the connecting piece is an isosceles trapezoid and its cross-sectional contour is equal to that of the inner cross-sectional contour of the outer shell. The inside has an isosceles trapezoidal slot corresponding to the shape of the outer contour, and the cross-sectional contour of the isosceles trapezoidal slot is equal to the outer contour of the isosceles trapezoidal end cross-section of the irregular inner shell.

[0013] Furthermore, the outer shell, main shell, connecting pipe, and connecting piece are all connected by welding.

[0014] This utility model uses an isosceles trapezoidal outer shell in conjunction with an irregularly shaped inner shell. The irregularly shaped inner shell gradually transforms from an isosceles trapezoid into a circle, resulting in a natural and smooth transition and a more aesthetically pleasing overall design.
