Description
Technical Field
The utility model belongs to the technical field of mounting brackets for vehicles, and particularly relates to a mounting and vibration isolation structure for an electric compressor for a vehicle and the vehicle.
Background
In a traditional fuel engine vehicle, a compressor is arranged on the side of an engine wheel train and vibration isolation is carried out through suspension of a power assembly. Compared with the traditional belt drive compressor, the displacement of the electric compressor is only 1/4-1/5 of that of the traditional belt drive compressor, but the running speed range can reach 8000-10000 rpm, which is more than twice that of the traditional mechanical belt drive compressor, the source excitation is larger, and the vibration noise risk is larger. If the electric compressor is arranged on the electric drive by referring to the traditional fuel oil automobile, vibration isolation is carried out by means of electric drive suspension, and the mode coupling of the cylinder body between the operation frequency band of the electric compressor and the electric drive shell exists, so that a series of problems such as vibration noise of the electric drive and even damage of the electric drive are excited, and the NVH problem of the thermal management system of the new energy automobile is further highlighted; particularly, the air conditioner is used for refrigerating and heating, the power battery is used for cooling, the electric drive and the controller are used for cooling, the electric compressor is needed to intervene, noise and vibration are generated in the running process of the electric compressor, and NVH (noise and vibration harshness) problems generated by part of vehicle type electric compressors are larger than the influence of the electric drive.
For automobile factories, most of electric drives are purchased samples and are not produced by the electric drives, and part of electric drive factories are not willing to add other system components on the electric drives or reserve the installation positions of other system samples. And secondly, compared with a fuel power assembly, the electric drive of the pure electric vehicle is small in size, and compared with fuel oil, the electric drive of the pure electric vehicle mostly adopts precursor configuration, and the same new energy vehicle type can be configured by precursor, four-wheel drive, rear drive and the like. Even if the electric compressors of the front drive and the four-drive vehicle type can be arranged on the front electric drive, the rear drive configuration vehicle type cannot be commonly used all the time; even like the parallel type hydrogen fuel cell rear-drive vehicle type, the hydrogen fuel cell stack has huge volume, occupies most of the space of the front cabin, and cannot be provided with a large-volume compressor vibration isolation structure. If the electric compressor is in vibration isolation by being placed on the electric drive and suspended by the electric drive, the electric compressor needs to be arranged on the rear electric drive, so that the arrangement difficulty and the cost of the thermal management system are increased in multiple, and the development difficulty is high.
Therefore, there is a need for developing a new motor-driven compressor mounting and vibration isolation structure for a vehicle and a vehicle.
