Description

Technical Field

[0001] The present invention relates to the technical field of automotive component processing, and more specifically, to a modular structure of an automotive rear wheel housing. Background Art

[0002] The automotive rear wheel housing is one of the important components of an automobile. The existing automotive rear wheel housing is usually an integral sheet metal stamping structure with complex shape features, high mold manufacturing costs, and deep drawing depth. Quality defects such as hidden damages and cracks are likely to occur in the parts, and the scrap rate is relatively high.

[0003] In addition, the existing rear wheel housing structure of an automobile also has the problem of poor versatility and cannot meet the requirements of the wheel housing space for different tire widths and wheelbases.

[0004] Therefore, in order to solve the above technical problems, there is an urgent need in the market for an automotive rear wheel housing structure with a simple structure, low cost, and certain versatility. Summary of the Invention

[0005] For this reason, the purpose of the present invention is to propose a modular structure of an automotive rear wheel housing, and its specific technical solution is as follows:

[0006] A modular structure of an automotive rear wheel housing is symmetrically assembled at the left and right rear wheel space positions of the frame assembly. Each rear wheel housing structure is composed of an outer rear wheel housing panel and an inner rear wheel housing panel. Among them,

[0007] The outer rear wheel housing panel is located on the outer side of the rear wheel space of the frame assembly. The upper part is an arc-shaped outer panel structure, and the lower part is a vertical side outer panel structure connected to both ends of the arc-shaped outer panel structure along the vehicle length direction. The connection between the arc-shaped outer panel structure and the vertical side outer panel structure is a fillet transition;

[0008] The inner rear wheel housing panel is located on the inner side of the rear wheel space of the frame assembly. The inner rear wheel housing panel includes an arc-shaped inner panel structure adapted to the radian of the arc-shaped outer panel structure and a vertical side inner panel structure adapted to the length of the vertical side outer panel structure; the connection between the arc-shaped inner panel structure and the vertical side inner panel structure is a fillet transition, and the outer rear wheel housing panel can just overlap on the inner rear wheel housing panel; on the side of the inner rear wheel housing panel away from the outer rear wheel housing panel is a vertical inner panel plane, and the connection between the vertical inner panel plane and the arc-shaped inner panel structure and the vertical side inner panel structure is a fillet transition;

[0009] The bottom edge of the vertical side outer panel structure and the overall bottom edge of the vertical side inner panel structure and the vertical inner panel plane are all connected to the frame assembly.

[0010] The present invention provides an automobile rear wheel housing structure with a simple structure, reliable process, certain versatility and low cost, which meets the space requirements of the body platform for different wheel housings.

[0011] Based on the above technical solutions, the present invention can also be improved as follows:

[0012] Preferably, a relief structure with a corresponding thickness is designed at the overlapping part of the inner panel of the rear wheel housing and the outer panel of the rear wheel housing. This relief structure makes the plane formed after the outer panel of the rear wheel housing overlaps with the inner panel of the rear wheel housing flush with the adjacent outer surface of the inner panel of the rear wheel housing.

[0013] The above relief structure makes the outer surface of the entire automobile rear wheel housing structure smooth as a whole, which not only ensures the connection strength of the automobile rear wheel housing, but also ensures the overall aesthetic appearance of the automobile rear wheel housing.

[0014] Preferably, the bottom edge of the vertical side outer plate structure, the vertical side inner plate structure and the overall bottom edge of the vertical inner plate plane have a flange edge extending horizontally outwards for connecting with the vehicle frame assembly. The flange edge overlaps on the vehicle frame assembly and is welded and assembled by resistance welding.

[0015] The flange edge can make the overall structure of the automobile rear wheel housing more firmly fixed on the vehicle frame assembly.

[0016] Preferably, after the flange edge is welded to the vehicle frame assembly, sealant is applied at the overlapping position to ensure a more beautiful and tighter connection between the flange edge and the vehicle frame assembly.

[0017] Preferably, by adjusting the length of the outer panel of the rear wheel housing in the vehicle width direction, the space size of the wheel housing can be adjusted to adapt to different vehicle models.

[0018] Preferably, the outer panel of the rear wheel housing overlaps on the inner panel of the rear wheel housing and is welded and assembled by resistance welding.

[0019] A modular automobile rear wheel housing structure of the present invention simplifies the original rear wheel housing structure and reduces the manufacturing process difficulty while meeting the requirements of structural strength and stiffness. This split design method meets the manufacturing requirements of automobile modularization and generalization. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment:

[0033] The following will Figures 1-4 describe in detail a modular structure of an automobile rear wheel housing according to an embodiment of the present invention.

[0034] As Figure 1 、 2 shown, an embodiment of the present invention discloses a modular structure of an automobile rear wheel housing. There are two such structures, which are symmetrically assembled at the left and right rear wheel spaces of the frame assembly 1.

[0035] As Figure 3 、 4 shown, each rear wheel housing structure is composed of an outer rear wheel housing panel 2 and an inner rear wheel housing panel 3. The outer rear wheel housing panel 2 overlaps the inner rear wheel housing panel 3 and is welded and assembled by resistance welding. Among them,

[0036] the outer rear wheel housing panel 2 is located at the outer side of the rear wheel space of the frame assembly 1. Its upper part is an arc-shaped outer panel structure 21, and its lower part is two vertical side outer panel structures 22 connected to both ends of the arc-shaped outer panel structure 21 along the vehicle length direction. The connection between the arc-shaped outer panel structure 21 and the two vertical side outer panel structures 22 is a fillet transition.

[0037] The inner panel 3 of the rear wheel housing is located inside the rear wheel space of the frame assembly 1. The inner panel 3 of the rear wheel housing includes an arc-shaped inner panel structure 31 adapted to the arc of the arc-shaped outer panel structure 21 and a vertical side inner panel structure 32 adapted to the length of the vertical side outer panel structure 22; the connection between the arc-shaped inner panel structure 31 and the vertical side inner panel structure 32 is also a fillet transition; the above structure enables the outer panel 2 of the rear wheel housing to just overlap on the inner panel 3 of the rear wheel housing and be welded and assembled by resistance welding.

[0038] Furthermore, a relief structure 34 with a corresponding thickness is designed on the overlapping part of the inner panel 3 of the rear wheel housing and the outer panel 2 of the rear wheel housing. This relief structure 34 makes the plane formed after the outer panel 2 of the rear wheel housing overlaps with the inner panel 3 of the rear wheel housing flush with the adjacent outer surface of the inner panel 3 of the rear wheel housing to ensure the smoothness of the entire outer surface of the rear wheel housing of the vehicle.

[0039] One side of the inner panel 3 of the rear wheel housing away from the outer panel 2 of the rear wheel housing is a vertical inner panel plane 33, and the connection between this vertical inner panel plane 33 and the arc-shaped inner panel structure 31 and the vertical side inner panel structure 32 is also a fillet transition.

[0040] The bottom edge of the vertical side outer panel structure 22 and the overall bottom edge of the vertical side inner panel structure 32 and the vertical inner panel plane 33 are all connected to the frame assembly 1.

[0041] Specifically, the bottom edge of the vertical side outer panel structure 22 and the overall bottom edge of the vertical side inner panel structure 32 and the vertical inner panel plane 33 have a flange edge 4 extending horizontally outward for connection with the frame assembly 1. This flange edge 4 overlaps on the frame assembly 1 and is welded and assembled by resistance welding, and further sealant is applied at the overlapping position for sealing.

[0042] The outer panel 2 of the rear wheel housing of the present invention is integrally an arc-shaped structure. By adjusting the length of the outer panel 2 of the rear wheel housing in the vehicle width direction, the size of the wheel housing space can be adjusted to achieve assembly with vehicles having different wheel housing space requirements.

[0043] This split design method of the outer panel 2 + inner panel 3 of the rear wheel housing of the present invention simplifies the original rear wheel housing structure while meeting the requirements of structural strength and stiffness, and at the same time reduces the manufacturing process difficulty, meets the manufacturing requirements of vehicle modularization and generalization, and is suitable for popularization and application.

[0044] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts among the various embodiments can be referred to each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0045] The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
