Description

Technical Field

[0001] The utility model relates to the technical field of go-kart exhaust pipes, in particular to an exhaust pipe with a silencer structure for indoor go-karts. Background Art

[0002] Go-karts are miniature sports cars. Their simple structure, high safety, and exceptional racing characteristics have made them extremely popular in countries like Europe and Japan. Go-karts are a type of racing car. According to current international regulations, they can only be powered by a small gasoline engine or electric motor. Gasoline-powered karts inevitably have exhaust pipes and other components, and karts used for indoor recreation require some form of exhaust silencing.

[0003] Existing devices primarily reduce noise by installing a muffler on the outer wall of the exhaust pipe. Much of the prior art resembles an exhaust pipe muffler device. Patent number CN207349678U includes an exhaust pipe comprising an air inlet and an air outlet. A fan is disposed near the air outlet, and a mounting frame is disposed on the outer peripheral wall of the exhaust pipe. The mounting frame includes a plurality of parallel horizontal beams and a plurality of parallel vertical beams. The horizontal and vertical beams are arranged perpendicularly to each other and form a plurality of openings filled with sound insulation material. While the sound insulation material is secured by the mounting frame to reduce noise transmission, the device still has room for improvement.

[0004] The existing devices mainly install an integrated silencer component on the outer wall of the exhaust pipe, which makes it difficult to quickly assemble and replace the silencer material in some devices, thereby making it inconvenient to maintain the silencer component of the exhaust pipe. At the same time, it is difficult to quickly expose or seal the silencer material in some devices, thereby making it inconvenient to assemble the silencer material, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, an exhaust pipe with a silencer structure for indoor karts is proposed. Utility Model Content
