Abstract

The invention discloses a rear traction device and an automobile. The rear traction device comprises a rear floor cross beam arranged on an automobile vehicle, a longitudinal beam connected with the rear floor cross beam, a traction hook lower mounting plate and a traction hook upper mounting plate. The traction hook lower mounting plate comprises a first connecting part connected with the longitudinal beam, a second connecting part connected with the rear floor cross beam and a third connecting part connected with the traction hook upper mounting plate. The first connecting part and the thirdconnecting part are located on the two sides of the second connecting part correspondingly, and the third connecting part is exposed out of the side, away from the longitudinal beam, of the rear floor cross beam. The traction hook upper mounting plate comprises a fourth connecting part connected with the third connecting part and a fifth connecting part connected with the rear floor cross beam. Aspace for mounting a traction hook nut is formed between the traction hook upper mounting plate and the traction hook lower mounting plate. According to the technical scheme provided by the invention, when the nut bears traction force, the traction force can be transmitted to the rear floor cross beam and the longitudinal beam, stress is dispersed, and welding spots are also not prone to being stripped.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a rear traction device and an automobile. Background technique [0002] Such as figure 1 As shown, the current rear traction device of a traditional passenger car is to weld the tow hook nut 8 through the rear anti-collision beam 1 on the tow hook mounting bracket 2, and the tow hook mounting bracket 2 is fixed to the rear end plate 3 of the car body by screws. In fact, this rear traction device has problems such as poor tensile strength, cracking of the bracket, and failure of solder joints. Contents of the invention [0003] The main purpose of the present invention is to provide a rear traction device and an automobile, aiming to solve the technical problems of the existing rear traction device such as poor tensile strength, cracking of brackets, and failure of solder joints. [0004] To achieve the above object, the rear traction device provided by the present inventi...
