Abstract

The invention provides a connection device between a subframe and a vehicle body, wherein the connection device includes two ends, namely a first end and a second end, the first end is fixedly connected to the subframe, and the second end Fixedly connected to the vehicle body, the second end includes at least one vehicle body side connection end and at least one vehicle body bottom panel connection end, the vehicle body side connection end is fixedly connected to the vehicle body side, and the vehicle body bottom panel connection end is fixedly connected to the vehicle body bottom panel. The invention also provides an automobile using the connecting device. The multi-point rigid connection method of the connection device of the present invention has good force transmission performance, and can transmit the collision force of the sub-frame to the vehicle body from multiple directions, reducing the amount of the sub-frame intruding into the cockpit during a collision.

Description

technical field [0001] The invention relates to a connection device between an auxiliary frame and a vehicle body and an automobile using the same. Background technique [0002] With the development of society, cars, as a means of transportation, are gradually entering every family. Users have higher and higher requirements for the performance of cars, but the safety requirements are still the first. This requires that the vehicle must be able to protect the safety of the occupants well under different circumstances. However, the existing connection structure between the sub-frame and the body sometimes cannot meet this requirement. In the process of car design, this kind of similar connection structure plays an important role, and their performance directly affects the driving stability of the car. and security. [0003] The performance of the connection structure between the sub-frame and the body indirectly affects the comfort and safety of the car. Most of the existin...
