Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
The application provides a shockproof resistance to compression type vehicle chassis pencil structure includes: the wire harness protective sleeve comprises a wire harness body and a protective sleeve, wherein the integral structure of the protective sleeve is a hollow tubular structure, a heat dissipation channel 2 is arranged in the protective sleeve, and the heat dissipation channel 2 longitudinally penetrates through the whole protective sleeve; the protective sheath includes protective sheath inlayer and protective sheath skin, and the rule is provided with a plurality of connection structure 1 between protective sheath inlayer and the protective sheath skin, and connection structure 1 inside cavity, connection structure 1 side are provided with the gas pocket.
Specifically, the wire harness body is provided in the wire harness installation region 8 within the protective sheath, and a plurality of wire harness bodies are separately provided therebetween by the connection structure 1.
Specifically, the protective sleeve inner layer comprises a protective sleeve inner layer inner side 6 and a protective sleeve inner layer outer side 7, and the protective sleeve inner layer is an area formed by the protective sleeve inner layer inner side 6 and the protective sleeve inner layer outer side 7; the protective sheath skin includes the outer outside 5 of protective sheath, and the protective sheath skin is the region that the outer outside 5 of protective sheath and the protective sheath inlayer outside 7 formed.
The connecting structure 1 is horn-shaped and hollow, and the horn-shaped connecting structure 1 comprises a flared end 3 and a necking end 4; wherein 3 one sides of flaring end are connected with protective sheath skin outside 5, and 4 one sides of throat end are connected with the inboard 6 of protective sheath inlayer, and the inboard 6 of protective sheath inlayer of junction has the exhaust hole that suits with 4 sizes of throat end, makes connection structure 1 can carry out gas exchange with the outside.
