Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] Such as Figure 5 to Figure 9 The vibration-absorbing structure of a motor shown includes a mounting base 14, a motor assembly, and several connecting structures for connecting the motor assembly to the mounting base 14. The connecting structure includes a connecting column 12 and a fixed connection with the tail end of the connecting column 12. The rubber block 13, the head end of the connecting column 12 and one of the rubber block 13 are fixedly connected on the installation base 14, and the other one of the head end of the connecting column 12 and the rubber block 13 is fixedly connected on the motor assembly.

[0028] In this embodiment, the rubber block 13 is fixedly connected to the end surface of the tail end of the connecting column 12 by bonding.

[0029] In this embodiment, the rubber block 13 is fixedly connected to the installation base 14 by bonding. ...

Abstract

The invention relates to a motor vibration absorption structure, which comprises a mounting base, a motor assembly and a plurality of connecting structures for connecting the motor assembly to the mounting base, wherein each connecting structure comprises a connecting column and a rubber block fixedly connected with the tail end of the connecting column, one of the head end of the connecting column and the rubber block is fixedly connected to the mounting base, and the other of the head end of the connecting column and the rubber block is fixedly connected to the motor assembly. According to the invention, the motor assembly is used as a mass block to form the motor vibration absorption structure, the vibration absorption function is realized under the premise of ensuring the normal use ofthe motor on the vehicle body, the problems of cost increase and weight increase are relieved or eliminated, and the power economy and weight reduction of the whole vehicle are facilitated.

Description

technical field [0001] The invention relates to automobile noise control technology, in particular to a vibration-absorbing structure of a motor. Background technique [0002] As customers demand higher and higher ride comfort, the continuous improvement of interior sound quality has become a challenging task for many NVH engineers. The first-order natural frequency of the body component modal is usually tens of Hz to tens of Hz , it is easy to be excited by the engine and the road surface, and interacts with the chassis suspension mode, the vehicle bending and torsion mode, and the acoustic cavity of the passenger compartment to radiate noise into the car. When the modes are coupled, it is easy to deteriorate the noise inside the car and form low-frequency roar (with There is a strong sense of ear pressure). Therefore, in the late stage of automobile body development, it is necessary to perform NVH tuning on the vehicle. In order to realize the modal decoupling of body par...
