Embodiment 1

[0047] like figure 1 As shown, the embodiment of the present invention provides a trailing arm rear suspension fixing device, which includes a mounting plate 1, a reinforcing plate 2 and a mounting part 3;

[0048] like figure 1 shown, and see figure 2 and image 3 , the two ends of the mounting plate 1 are bent in the same direction to form two mounting plate bending parts 11, and the surrounding edges of the reinforcing plate 2 are bent in the same direction to form four reinforcing plate bending parts 21;

[0049] The reinforcement plate 2 is fixed on the rear floor 4 of the automobile through the two corresponding reinforcement plate bending portions 21, and the reinforcement plate 2 is fixed on the rear longitudinal beam 5 and the door sill beam of the automobile through the other two reinforcement plate bending portions 21 between 6;

[0050] like figure 2 shown, and see Figure 4 , the mounting plate 1 is fixed on the rear floor 4 of the automobile through the t...

Embodiment 2

[0082] An embodiment of the present invention provides an automobile, which includes a trailing arm rear suspension fixing device.

[0083] The embodiment of the present invention uses the trailing arm rear suspension fixing device, and the trailing arm rear suspension fixing device is fixed between the rear longitudinal beam 5 and the door sill beam 6, and the unnecessary surface area of ​​the rear longitudinal beam 5 is subtracted, not only The material is saved, and the weight of the vehicle body is also reduced; in the device, the mounting plate 1, the reinforcing plate 2, the rear floor 4, the rear longitudinal beam 5, and the sill beam 6 of the automobile form a box-shaped structure, and the mounting part 3 is arranged on the mounting plate 1 Between the reinforcement plate 2, keep a certain distance between the installation plate 1 and the reinforcement plate 2. This structure can disperse the force, prevent the phenomenon of stress concentration, and improve the strengt...

Abstract

The invention discloses a trailing arm rear suspension fixing device and an automobile, belonging to the field of automobile design. The trailing arm rear suspension fixing device includes a mounting plate, a reinforcement plate and a mounting part; the mounting plate, the rear longitudinal beam of the automobile, the door sill beam and the rear floor form a box-like structure, and the reinforcement plate is located in the box In the shape structure; the installation part is located between the installation plate and the reinforcement plate, and the two ends are respectively connected with the installation plate and the reinforcement plate, and the rear suspension of the trailing arm is fixed on the trailing arm through the installation part. on the rear suspension mount. In the present invention, by fixing the trailing arm rear suspension fixing device between the rear longitudinal beam and the sill beam, the unnecessary surface area of ​​the rear longitudinal beam is subtracted, which not only saves materials, but also reduces the weight of the vehicle body; the box of the device The shape structure can disperse the force and prevent the phenomenon of stress concentration; the mounting plate is also provided with reinforcing ribs to improve the strength and rigidity of the fixing device.

Description

technical field [0001] The invention relates to the field of automobile design, in particular to a trailing arm rear suspension fixing device and an automobile. Background technique [0002] The trailing arm rear suspension is a suspension structure designed for the rear wheels of the car, which is used to realize the connection between the rear wheels and the body. The shock absorber and coil spring on the rear suspension of the trailing arm can absorb the impact force of the road on the wheel so as to absorb the shock and support the body, providing the driver with a more stable and safer driving environment. [0003] The current trailing arm rear suspension is fixedly installed on the rear longitudinal beam of the car by bolts. In order to ensure sufficient strength, a mounting reinforcement plate is welded on the inner lining of the rear longitudinal beam, and the bolts pass through the rear longitudinal beam and the installation reinforcement plate successively. [000...
