Description

Technical Field

[0001] The present application relates to a wheel rim applicable to new energy vehicles, belonging to the technical field of wheel rims. Background Art

[0002] The rim, commonly known as the wheel circle, is a component for mounting and supporting a tire on the periphery of a wheel. It forms a wheel together with the wheel spoke. The rim and the wheel spoke can be integral, permanently connected, or detachable. The rim and the tire cooperate to bear the load of the entire vehicle. During the use of the vehicle, complex road conditions are encountered, so the rim will be subjected to strong alternating loads. When the rim is subjected to strong alternating loads, its wear will be aggravated and even deformation will occur, which will not only affect the assembly of the tire, but also increase the probability of tire detachment during normal driving.

[0003] New energy vehicles are a new development direction in the automotive industry. There are great differences in the power generation method, power transmission method, and chassis layout between new energy vehicles and fuel vehicles. During the road driving verification process of new energy vehicles, the rim structure designed according to traditional fuel vehicles has problems such as cracking of the inner rim edge and reduction of the service life of the bead of the automotive rubber tire, posing great potential safety hazards.

[0004] Therefore, there is an urgent need to provide a wheel rim structure applicable to new energy vehicles to improve the safety and stability of new energy vehicles during driving. Utility Model Content

[0005] In order to solve the above problems, the present application proposes a wheel rim applicable to new energy vehicles. This wheel rim can effectively protect the bead of the automotive rubber tire, extend the service life of the automotive rubber tire, and also has the advantage of being easy to assemble.

[0006] The present application provides a wheel rim applicable to new energy vehicles, including a rim body. The rim body is provided with an outer rim edge, an assembly groove, and an inner rim edge. An outer bead seat is arranged beside the outer rim edge, and the outer rim edge is of an annular structure. The outer rim edge bends inward to be connected to the outer side of the outer bead seat. The inner rim edge is of an arc-shaped structure, and an inner bead seat is arranged beside the outer rim edge. The assembly groove is arranged in the middle of the rim body, and the assembly groove includes an upper edge on the outer side of the assembly groove and an upper edge on the inner side of the assembly groove. Both the upper edge on the outer side of the assembly groove and the upper edge on the inner side of the assembly groove are upwardly convex arc segments.

[0007] Optionally, the height of the upper edge on the outer side of the assembly groove is greater than the height of the upper edge on the inner side of the assembly groove.

[0008] Optionally, the height of the outer rim edge is greater than the height of the inner rim edge.

[0009] Optionally, a convex portion is further arranged in the middle of the assembly groove.

[0010] Optionally, the convex portion is arc-shaped, and the arc radius of the convex portion is R1, where 5 ≤ R1 ≤ 10.

[0011] Optionally, the arc radius of the inner rim is R2, where 10 mm ≤ R2 ≤ 15 mm.

[0012] Optionally, the arc radius of the upper edge of the outer side of the assembly groove is R3, and the arc radius of the upper edge of the inner side of the assembly groove is R4, where R3 < R4.

[0013] Optionally, the distance between the upper edge of the outer side of the assembly groove and the outer rim is L1, and the distance between the upper edge of the inner side of the assembly groove and the inner rim is L2, where L1 > L2.

[0014] The wheel rim provided by this application has the following advantages:

[0015] This wheel rim can effectively protect the bead of the automotive tire and extend the service life of the automotive tire, and also has the advantage of being easy to assemble;

[0016] Since new energy vehicles need to carry an additional battery module compared with traditional vehicles, they have a greater load capacity. The wheel rim provided by this application is provided with an assembly groove and a convex portion in the middle, which can reduce the deformation amount of the inner rim under heavy load conditions, thereby improving the fixing stability of the tire and the wheel rim under heavy load conditions.
