At the same time, it is also necessary to ensure a certain degree of sealing and stability of the installation structure. The intake pipe must ensure sufficient flow area to reduce air resistance. Usually, the intake pipe is generally connected and installed with an intake rubber tube with a corrugated structure.

[0003] The current automobile air intake pipe is composed of a hard pipe and a soft pipe. When the hard pipe is connected to the soft pipe, the hard pipe or the soft pipe is prone to deviation, resulting in low sealing at the engine connection, poor air transmission effect, and affecting use. In addition, due to the complex internal structure of the automobile and limited operating space, bolts are used to install the air intake rubber pipe, which is inconvenient to connect and time-consuming and labor-intensive. Therefore, the utility model designs an air intake rubber pipe that is easy to install and has a corrugated structure to solve the problems existing in the prior art. Utility Model Content
