Abstract

The invention discloses a motor cladding structure integrating sound absorption and anti-collision performance. The motor cladding structure comprises a first substrate and a second substrate, whereina plurality of bosses are correspondingly and uniformly distributed on one side surfaces of the first substrate and the second substrate, the bosses on the first substrate and the second substrate are enclosed to form a half cavity, a plurality of through holes are formed in the bottom surface of the half cavity on the first substrate, and the bosses of the second substrate are fixed on the corresponding bosses of the first substrate, therefore, a plurality of cavity structures composed of two half cavities are formed between the two layers of substrates, and the cavity structures and corresponding through holes form Helmholtz resonance cavities. The motor coating structure is simple in structure and easy to realize; moreover, one side surface of the first substrate provided with the through hole is contacted with the motor, the middle cavity structure and the through hole form a series of Helmholtz resonance cavities, high-frequency noise emitted by the motor can be efficiently processed, and the motor is protected when being impacted by the outside.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a motor covering structure integrating sound absorption and anti-collision performance. Background technique [0002] As human beings attach importance to the natural environment, electric vehicles are being vigorously promoted as a new energy vehicle. The internal power system of an electric vehicle relies on the motor inside the vehicle. As a precision rotating component, the motor generates high-frequency noise and is easily damaged in the event of a collision. Contents of the invention [0003] The purpose of the present invention is to provide a motor covering structure integrating sound absorption and anti-collision performance, so as to solve the problems in the prior art that the motor of an electric vehicle generates high-frequency noise during operation and is easily damaged during collision. [0004] For reaching this purpose, the present inven...
