Pipe joint, engine assembly and vehicle

Abstract

The invention relates to a pipe joint, an engine assembly and a vehicle. The pipe joint is used for communicating a pipeline with a mounting hole of a first substrate, the hole bottom of the mountinghole is formed as a reduced diameter part; and the pipe joint comprises a core pipe, a mounting part, the core pipe comprises a straight pipe part and a first corrugated section formed at one end of the straight pipe part and radially protruding, and the core pipe is a metal pipe; the mounting part is of a hollow structure, the mounting par sleeves the straight pipe part and is axially limited bythe first corrugated section, the pipe joint can extend into the mounting hole and is locked on the first base body through the mounting part, so that the first corrugated section is axially extrudedbetween the end part of the mounting part and the hole bottom, the wave crest of the first corrugated section radially abuts against the inner wall of the mounting hole, and the mounting hole communicates with a flow channel in the first base body, and the inner diameter of the core pipe is larger than or equal to the inner diameter of the flow channel. The pipe joint is installed, and the wave crest of the first corrugated section extends outwards in the radial direction and abuts against the inner wall of the installation hole under the extrusion action to play a sealing role. According to the pipe joint, parts are fewer, and the installation is convenient.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle manufacturing, in particular, to a pipe joint, an engine assembly and a vehicle. Background technique [0002] In most mechanical devices, oil passages and water passages are required to lubricate and cool the mechanical devices. For example, in the field of engines, the oil passages and water passages of the engine need to be connected to the pipelines of the oil tank and water tank outside the engine through pipe joints. At present, the structure of the pipe joint includes flanges, bolts for fixing the flanges and seals, and the seals are usually O-rings or sealing gaskets. However, the existing pipe joints are composed of many parts, which increases the cost of parts and labor costs during installation, and also greatly reduces the production cycle when the engine is mass-produced. Contents of the invention [0003] A first object of the present disclosure is to provide a pipe joint...
