[0001] The utility model relates to the technical field of vehicles, in particular to a motor mount structure and a vehicle. Background Art

[0002] With the rapid development of the automotive industry, in order to conform to the concept of energy conservation and emission reduction, the rise of pure electric vehicles is irresistible. The power type of pure electric vehicles is replaced by a motor, and the motor mount structure system is usually arranged based on the center of mass of the powertrain, adopting three-point mounting. Two mounts are arranged in front of the motor and one mount is arranged behind the motor, and then all three mounts are installed on the subframe.

[0003] In order to avoid the metal impact noise between the motor mount structure and the subframe when the powertrain moves left and right, a rubber gasket structure is usually added to the end of the bushing of the rear motor mount structure for buffering and noise reduction. The rubber gasket at the end is manually sleeved on the inner core of the mount bushing, rather than fixed on the inner core of the mount bushing. The rubber gasket can move left and right, and it is impossible to ensure the consistency of the component state. There is a risk of the rubber gasket falling off during transportation. When the motor mount structure is assembled with the subframe, it is easily squeezed and deformed by the mount installation bracket on the subframe, thus causing the metal impact noise between the mount and the subframe and customer complaints. Summary of the Utility Model
