Description

Technical Field

[0001] This utility model belongs to the field of automotive component technology, and more specifically, it relates to a vehicle rear wheel arch body connection structure. Background Technology

[0002] Advances in automotive technology have intensified competition among automakers, leading to higher performance targets. Currently, wheel arches are coated with sealant to prevent mud, water, and gravel splashed up by the wheels from entering the vehicle body, while also providing sound and heat insulation. However, the wheel arches are also where shock absorbers are mounted. The dynamic stiffness of the shock absorber mounting points is directly proportional to the strength of the wheel arch. However, the use of sealant for convenience has resulted in compromised structural strength of the wheel arches, leading to a less-than-ideal ride comfort in the passenger compartment and further noise reduction.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a car rear wheel arch body connection structure in order to achieve a more practical purpose. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a vehicle rear wheel arch body connection structure, which solves the problem that the sealing of the wheel arch is compromised due to the ease of applying adhesive, resulting in poor structural strength, poor vibration damping experience in the driver's cabin, and noise that still needs to be reduced.

[0005] The purpose and function of this utility model's automobile rear wheel arch body connection structure are achieved by the following specific technical means:

[0006] A vehicle rear wheel arch body connection structure includes a crossbeam, on which a floor sheet metal is welded. One side of the crossbeam is connected to the wheel arch. A first longitudinal beam and a second longitudinal beam are respectively provided on the outer side of the wheel arch. The bottom of the first longitudinal beam extends to fit the crossbeam and connect to the floor sheet metal. The top of the first longitudinal beam fits the wheel arch and connects to the D-pillar. The bottom of the second longitudinal beam extends on the floor sheet metal and connects to a second longitudinal beam on the other side of the wheel arch. The top of the second longitudinal beam fits the wheel arch and extends upward to connect to the C-pillar.

[0007] Furthermore, both the first longitudinal beam and the second longitudinal beam have welded edges.

[0008] Furthermore, a longitudinal beam outer plate is installed on the inner side of the wheel cover, and the longitudinal beam outer plate is inverted U-shaped.

[0009] Furthermore, a connecting surface is formed around the periphery and center of the outer plate of the longitudinal beam, and the connecting surface corresponds to the position of the weld edge.

[0010] Furthermore, a vertical edge extends upward from the outer side of the crossbeam, the wheel cover is connected to the vertical edge, and the bottom of the outer plate of the longitudinal beam is connected to the crossbeam by bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By changing the geometry of the wheel arch connecting to the floor sheet metal, the first and second longitudinal beams ensure two structural adhesive seals on the water inlet channel, without interrupting the force transmission path of the vehicle body, ensuring the integrity of the force transmission structure and improving the dynamic stiffness of the shock absorber mounting point.

[0020] Example 1

[0021] As attached Figure 1 To be continued Figure 2 As shown:

[0022] This utility model provides a car rear wheel cover body connection structure, including a crossbeam 2, a floor sheet metal 1 welded on the crossbeam 2, a wheel cover 3 connected to one side of the crossbeam 2, which is shown as a car rear wheel cover 3 in this embodiment, a vertical edge 201 extending upward from the outer side of the crossbeam 2, the wheel cover 3 being connected to the vertical edge 201, increasing the height of the connection between the wheel cover 3 and the crossbeam 2, and extending the connection surface between the wheel cover 3 and the crossbeam 2.

[0023] The outer side of the wheel arch 3 is provided with a first longitudinal beam 4 and a second longitudinal beam 5. The bottom of the first longitudinal beam 4 extends to fit the crossbeam 2 and connects to the floor sheet metal 1. The top of the first longitudinal beam 4 fits the wheel arch 3 and connects to the D-pillar. The first longitudinal beam 4 improves the structural strength of the wheel arch 3, but only the single-line strength. The bottom of the second longitudinal beam 5 extends on the floor sheet metal 1 and connects to the second longitudinal beam 5 on the wheel arch 3 on the other side of the car to ensure the continuity of the force transmission path. The top of the second longitudinal beam 5 fits the wheel arch 3 and extends upward to connect to the C-pillar. The first longitudinal beam 4 and the second longitudinal beam 5 cooperate to improve the dynamic stiffness of the rear shock absorber and the torsion of the whole vehicle. The edges of the first longitudinal beam 4 and the second longitudinal beam 5 are provided with welded edges 7 to extend the contact surface with the wheel arch 3 when applying sealant.

[0024] The inner side of the wheel cover 3 is equipped with a longitudinal beam outer plate 6, which is inverted U-shaped. The longitudinal beam outer plate 6 enhances the rigidity of the inner side of the wheel cover 3. At the same time, the outer side and the middle of the longitudinal beam outer plate 6 form a connecting surface 601. The connecting surface 601 corresponds to the position of the welding edge 7, so that the connecting surface 601 and the welding edge 7 form corresponding welding points, connecting the longitudinal beams on the inner and outer sides of the wheel cover 3. The longitudinal beams overlap and are staggered in the z direction to form two rows of welding points, which improves the welding strength and structural strength.

[0025] The bottom of the outer plate 6 of the longitudinal beam extends beyond the vertical edge 201 and is connected to the crossbeam 2 by bolts. This ensures that after the outer plate 6 of the longitudinal beam is connected to the first longitudinal beam 4 and the second longitudinal beam 5, it is stable by combining with the crossbeam 2, so that the vibration of the shock absorber can be absorbed by the entire wheel cover 3 and the frame.

[0026] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
