Detachable type subframe support structure

The utility model relates to a component of a car, especially to a detachable type subframe support structure, which comprises connection plates disposed on both sides of a subframe, while respectively located between the subframe and a longitudinal beam of the car body; a mounting hole is formed on each connection plate; the connection plate is connected with the longitudinal beam of the car body by passing a fastening bolt through the mounting hole; a detaching hole enabling a fastening bolt to pass through and detach is formed on each connection plate, and at a position between the mounting hole and the head of the car; and the detaching hole is communicated with the mounting hole; The utility model achieves the beneficial effects that: a detaching slot is added at the position of the fastening bolt for connecting the subframe and the longitudinal beam, thereby when the car is gotten into a head-on collision, the fastening bolt can be detached from the detaching hole to cause the power assembly to sink; in this way, the support structure reduces impact of the power assembly to the front coaming plate, and can protect the personal safety of the driver and passengers in the car effectively.
