Problems solved by technology

[0003] The traditional motor will generate large vibration during use, and due to the influence of resonance, the noise generated by the motor will be relatively large, which not only affects the use of the motor, but also affects the power provided by the motor to the car. The vibration and heat dissipation cannot be improved well, so further improvement is needed on this basis

Abstract

The invention relates to the technical field of automobile motors, in particular to a new energy automobile motor with a built-in sound absorption structure. The new energy automobile motor with the built-in sound absorption structure comprises: a driving motor which is internally provided with the sound absorption structure and is used for reducing the noise of the driving motor during working; a damping mechanism which is fixedly connected with the driving motor and is used for improving the stability of the driving motor during working; and a heat dissipation structure which is fixedly connected to the interior of the driving motor and is used for reducing heat generated in the driving motor. The driving motor is internally provided with the sound absorption structure, so that the noise of the driving motor can be reduced to the maximum extent, the situation that the driving comfort is reduced due to the fact that the sound is too loud when people drive a vehicle is avoided, meanwhile, the stability and the heat dissipation condition of the motor during working are improved to a certain extent, and the situation that the service life of the driving motor is affected since aging phenomenon occurs in parts in the driving motor due to high temperature can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobile motors, in particular to a new energy automobile motor with a built-in sound-absorbing structure. Background technique [0002] New energy vehicle motor is a kind of motor used in new energy vehicles. Its function is to convert electric energy into kinetic energy and provide power for new energy vehicles. Its quality determines how far new energy vehicles can go. It is a new energy vehicle assembly important components in. [0003] The traditional motor will generate large vibration during use, and due to the influence of resonance, the noise generated by the motor will be relatively large, which not only affects the use of the motor, but also affects the power provided by the motor to the car. The vibration and heat dissipation can not be improved well, so further improvement is needed on this basis. Contents of the invention [0004] The purpose of the present invention is to provide a ne...
