Description

Technical Field

[0001] This utility model relates to the field of wheel rim technology, specifically to a deformation-resistant electric vehicle wheel rim with annular reinforcing ribs. Background Technology

[0002] As a key component for load bearing and force transmission, the wheel rim design must simultaneously meet multiple requirements such as lightweight, high strength, and resistance to deformation. Currently, electric vehicle wheel rims are mostly made of materials such as aluminum alloy, magnesium alloy, or high-strength steel, and are formed through casting, forging, or rolling processes. The typical structure includes the wheel rim body, the spoke connection, and functional holes such as valve stem holes and balance weight mounting slots. To achieve lightweighting, existing wheel rims generally adopt a thin-walled design, and some products improve structural strength by locally thickening the rim edge, setting straight reinforcing ribs, or adding reinforcing plates at the spoke connection.

[0003] Although existing technologies have improved rim performance to some extent through lightweight design and local reinforcement measures, in actual applications, rims need to withstand greater radial loads during driving. The thin-walled structure or straight reinforcing ribs used in existing rims have limited radial support capacity. When driving fully loaded on bumpy roads, the rim body is prone to dents or bulges due to radial impact, which can lead to failure of the tire-rim seal, causing air leakage, abnormal tire pressure, or even the risk of tire blowout.

[0004] Therefore, a deformation-resistant electric vehicle wheel rim with ring-shaped reinforcing ribs is needed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a deformation-resistant electric vehicle wheel rim with annular reinforcing ribs to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A deformation-resistant electric vehicle wheel rim with annular reinforcing ribs, comprising: The rim body has outwardly protruding flanges on both sides, and an inwardly concave arc-shaped surface is provided between the two flanges. A reinforcing rib assembly is disposed on the wheel rim body to enhance the overall strength of the wheel rim body; The spoke condition is located on the inner side of the rim body.

[0007] As a preferred embodiment of this utility model, the reinforcing rib assembly includes an outer reinforcing rib and an inner reinforcing rib, which are respectively disposed on the outer and inner sides of the wheel rim body.

[0008] As a preferred embodiment of this utility model, the outer reinforcing rib includes an outer main reinforcing rib, a plurality of outer secondary reinforcing ribs a and a plurality of outer secondary reinforcing ribs b, the plurality of outer secondary reinforcing ribs a and a plurality of outer secondary reinforcing ribs b being symmetrically distributed on the inner side of the wheel rim body, and the outer main reinforcing rib being disposed in the middle of the inner side of the wheel rim body.

[0009] As a preferred embodiment of this utility model, the inner reinforcing rib includes an inner main reinforcing rib disposed in the middle of the concave arc-shaped surface, and inner secondary reinforcing ribs disposed on both sides of the inner main reinforcing rib.

[0010] As a preferred embodiment of this utility model, the cross-sections of the inner main reinforcing rib and the outer main reinforcing rib are designed with a gradual change, and the positions of the inner main reinforcing rib and the outer main reinforcing rib correspond to each other.

[0011] As a preferred embodiment of this utility model, the outer surfaces of the inner secondary reinforcing rib, the outer secondary reinforcing rib b, and the outer secondary reinforcing rib a are all arc-shaped.

[0012] As a preferred embodiment of this utility model, the spokes include a plurality of spokes arranged in a circumferential array, and the connecting end of the spokes to the rim body is provided with a groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention constructs a high-rigidity three-dimensional support frame by setting up annular reinforcing ribs that correspond to both the inner and outer surfaces. This greatly enhances the radial stiffness and bending resistance of the rim body, effectively resisting severe impacts from the road surface. When fully loaded or traveling on bumpy roads, the impact force can be quickly dispersed and absorbed through this main load-bearing frame, thereby fundamentally preventing the rim body from denting or bulging due to local stress concentration. This ensures the sealing reliability of the tire-rim joint and effectively prevents the risks of air leakage, abnormal tire pressure, and even tire blowout. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figure 1-3 This utility model provides a technical solution: For an example, please refer to... Figure 1 , 2 3, a deformation-resistant electric vehicle wheel rim with annular reinforcing ribs, comprising a wheel rim body 1 as the basic load-bearing structure, a reinforcing rib assembly for reinforcing the body, and a spoke configuration for transmitting driving and braking torque.

[0021] The rim body 1 forms the skeleton of the entire rim. It has outwardly protruding flanges 3 on both sides. The core function of these two flanges 3 is to reliably restrain the tire bead, ensuring that the tire does not come off the rim during inflation and driving, especially important during sharp turns or lateral impacts. Connecting the two flanges 3 is not a flat surface, but an inwardly concave arc-shaped surface 9. The design of the arc-shaped surface 9 cleverly reduces the overall weight of the rim while ensuring basic support strength, achieving lightweighting. This arc-shaped structure itself has good stress distribution characteristics, enabling it to absorb and disperse some energy through its elastic deformation when subjected to radial impact, serving as the first line of defense against deformation.

[0022] The reinforcing rib assembly is installed on the rim body 1, specifically divided into an outer reinforcing rib located on the outer side and an inner reinforcing rib located on the inner side. They reinforce the rim body from both the inner and outer sides to form a stable structure.

[0023] The outer reinforcing rib is located on the outer side of the rim body 1. It includes a main outer reinforcing rib 5 located in the central region of the arc-shaped surface, and several secondary outer reinforcing ribs a7 and b8 symmetrically distributed on both sides of the main outer reinforcing rib 5. The main outer reinforcing rib 5 serves as the core load-bearing ridge on the outer side. Its cross-section adopts a gradual design, that is, the thickness and height of the rib smoothly transition from the center to both sides. This can effectively disperse and transfer the concentrated impact force from the tire to a wider area of ​​the rim body 1, thereby avoiding stress concentration and preventing the rim from cracking or permanently deforming due to excessive local stress.

[0024] The inner reinforcing ribs are located on the inner side of the rim body 1, primarily to withstand the tension from the spokes and the torque generated during driving and braking. It includes an inner main reinforcing rib 4 and inner secondary reinforcing ribs 6 located on either side of the inner main reinforcing rib 4. The inner main reinforcing rib 4 and the outer main reinforcing rib 5 correspond to each other radially on the rim. This corresponding inner and outer arrangement allows the impact force, after being transmitted through the outer main reinforcing rib 5, to be directly and efficiently transferred to the inner main reinforcing rib 4. Together, they form a high-rigidity main load-bearing frame, greatly improving the bending and torsional resistance of the rim's center.

[0025] The spokes are used to connect the hub and the rim. In this embodiment, it includes multiple spokes 2 evenly distributed in an array along the circumference of the rim. To ensure the strength and precision of the connection point, a groove is specially provided at the end where the spoke 2 connects to the rim body 1. The groove can form a precise engagement and positioning with the connector on the rim, which not only enhances the firmness of the connection and prevents the spokes from rotating or shifting under force, but also simplifies the assembly process.

[0026] Working Principle and Synergistic Effect: During vehicle operation, when encountering a vertical impact, the ground impact force is transmitted through the tire to the concave arc-shaped surface 9. The main load-bearing frame, composed of the corresponding outer main reinforcing ribs 5 and inner main reinforcing ribs 4, takes effect first, providing strong radial support to resist overall bending deformation. For lateral impacts or complex torsional loads, the symmetrically distributed outer secondary reinforcing ribs a7, b8, and 6 work together. Their arc-shaped outer surface design helps guide and disperse stress, forming an efficient force flow transmission network that rapidly diffuses local stress, effectively preventing dents and deformation at the rim edge or in localized areas. The entire system, through the close cooperation between the basic structure of the rim body 1 and the interlocking network of reinforcing ribs, achieves high strength and high rigidity while maintaining lightweight design, ultimately resulting in excellent anti-deformation performance.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
