Problems solved by technology
[0003] The first type is a bellows formed by blow molding TPV (thermoplastic vulcanizate) material. This kind of bellows has a lot of residual material in the molding process, which leads to high molding costs, poor durability, poor dimensional accuracy, and poor sealing. Easy to collapse, poor motion compensation ability
[0004] The second is the corrugated tube formed by processing rubber (thermosetting material) through the injection process, such as vulcanized rubber. This type of rubber is formed through complex processes such as coking, and the molding process is difficult to control, resulting in the overall wall thickness of the product and the wave pitch of the corrugated section. Larger, high cost of raw materials, low production efficiency, and this type of rubber is a thermosetting material that cannot be injection molded

Embodiment Construction
[0025] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present disclosure, but are not intended to exhaust all possible ways of the present disclosure, nor are they used to limit the scope of the present disclosure.
[0026] Such as figure 1 with figure 2 As shown, the present disclosure provides a bellows for a vehicle, which can be used in the air intake system of the vehicle, for example, the bellows is used to connect a supercharger and an air filter, although the present disclosure is not limited thereto. The corrugated pipe includes a corrugated section 1, a turning section 2 and a connecting section 3. In a natural state, the corrugated section 1 is straight, the turning section 2 is curved, and the turning section 2 connects the corrugated section 1 and turns relative to the corr...

Abstract
According to the corrugated pipe for the vehicle, the corrugated pipe is provided with a corrugated section, the corrugated section is provided with a plurality of wave-shaped parts which are sequentially connected, so that the corrugated pipe has a plurality of wave crests and wave troughs, and when the corrugated pipe is in a natural state, the wave height of the wave-shaped parts is set in a first height range, and the wave crest angle is set in a first angle range; the wall thickness of the corrugated section is set to be within the first thickness range, when the corrugated pipe is integrally formed in the mode of injection molding of the thermoplastic elastomer, the corrugated pipe is easy to demould in the injection molding process, and the corrugated pipe has good collapse resistance and motion compensation capacity. The defects of blow molding production of corrugated pipes are avoided, the defects of complex rubber injection molding process and high raw material cost are overcome, and the production efficiency is improved.
Description
technical field [0001] The disclosure relates to engine accessories, in particular to a vehicle bellows. Background technique [0002] The outlet pipe of the air filter of the air intake system of the automobile engine is generally a bellows, and the existing bellows include the following two types: [0003] The first type is a bellows formed by blow molding TPV (thermoplastic vulcanizate) material. This kind of bellows has a lot of residual material in the molding process, which leads to high molding costs, poor durability, poor dimensional accuracy, and poor sealing. When it is easy to collapse, the motion compensation ability is poor. [0004] The second is the corrugated tube formed by processing rubber (thermosetting material) through the injection process, such as vulcanized rubber. This type of rubber is formed through complex processes such as coking, and the molding process is difficult to control, resulting in the overall wall thickness of the product and the wave...
