The invention discloses a back-suspension installation structure. The back-suspension installation structure comprises a back-floor longitudinal beam, a back floor and a back wheel cover. The back-floor longitudinal beam comprises a first side plate, a bottom plate and a second side plate, wherein the first side plate, the bottom plate and the second side plate are sequentially connected. The first side plate and the second side plate are oppositely arranged. The back floor is welded to the back-floor longitudinal beam and is opposite to the bottom plate. The back wheel cover is welded to the back floor. The back-suspension installation structure further comprises a back-suspension-limiting-block installation support, a back-suspension-spring installation support and a back-suspension-spring-installation-support supporting plate, the back-suspension-spring installation support is fixed to the bottom plate, the back-suspension-limiting-block installation support is fixed to the bottom plate through a back suspension spring, one end of the back-suspension-spring-installation-support supporting plate is fixed to the back-suspension-spring installation support, and the other end of the back-suspension-spring-installation-support supporting plate is fixed to the first side plate. According to the back-suspension installation structure, a back wheel cover reinforcement plate is avoided, haunch space can be increased while the weight of an automobile body is reduced, and welding spots between the back wheel cover and the back floor are not prone to crack.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a rear suspension installation structure and an automobile. Background technique [0002] MPV (Multi-Purpose Vehicles) is a car that combines the large passenger space of a station wagon, the comfort of a car and the functions of a van. MPV cars generally have a hatchback structure, with a complete and large passenger space and luggage space. Seats for 5-8 people can be arranged in the car. The seat configuration generally adopts two to three rows. The layout is flexible and can be fully folded or laid down. , some can also move back and forth, left and right, or even rotate, which gives it great flexibility in its internal structure. [0003] The existing MPV car layout is based on the car structure, which is produced on the car platform, and generally directly adopts the frame structure of the car. The frame structure is generally a support structure formed by multiple lo...
