Abstract

The invention discloses an automobile rear frame assembly and an automobile, relates to automobile parts techniques and solves the problem that the application of the prior rear frame assembly causes inefficiency of collision energy absorption and ease of oil tank damage and decreases safety of the automobile. The automobile rear frame assembly according to the embodiments comprises a rear impact beam; rear rail structures identical to each other are fixed to two ends of the same side of the rear impact beam; each rear rail structure comprises an outer longitudinal side member and an inner longitudinal middle member, the longitudinal side member and the longitudinal side member gather at the rear impact beam and then split and extend in parallel; the part, from the gathering position to the extension end, of each longitudinal side member is in arc structure, and the part, from the gathering part to the extension end, of each longitudinal middle member is in an arc structure; a rear cross beam is fixed between the longitudinal side members; the longitudinal middle members extend to the rear cross beam from the gathering positions; an oil tank is fixed on the longitudinal middle members; a connecting beam is fixed between the longitudinal middle members, corresponding to an oil tank area. The automobile rear frame assembly is mainly applied to automobiles.

Description

technical field [0001] The invention relates to vehicle accessory technology, in particular to an automobile rear frame assembly and an automobile. Background technique [0002] Nowadays, collisions or rear-end collisions are not uncommon in the process of driving a car. Among them, in order to reduce the degree of injury caused by the accident to the occupants of the car, the structural design of the rear frame assembly of the car plays a key role, which can absorb the Collision energy, thereby reducing collision momentum, etc. [0003] At present, the rear vehicle frame assembly in the prior art is as figure 1 As shown, it includes: a rear anti-collision beam 11, and the same side of the rear anti-collision beam 11 is fixedly connected with two rear longitudinal beams 12 arranged at intervals, wherein, the rear longitudinal beam 12 is provided with a fixed bracket 14 for supporting and fixing the fuel tank 13 . When the car collides rearward, the rear anti-collision bea...
