[0002] In modern transportation vehicles, as a key component connecting the tire and the vehicle, the design and performance of the rim directly affect the safety, handling and comfort of the vehicle. Traditional rims mostly adopt flat or simply curved structures, and the edge part lacks sufficient rigidity and strength, being prone to deformation when impacted, and even causing the tire to come off the rim, seriously threatening driving safety. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a rim with edge reinforcement to solve the problems raised in the above background art.

[0004] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0005] A rim with edge reinforcement, including a middle ring, edge rings are arranged at both ends of the middle ring, a reinforcement ring is arranged inside the edge ring, the edge ring and the reinforcement ring are connected end to end to form a cavity, and a sponge is arranged in the cavity.

[0006] Preferably, the surface of the edge ring in contact with the tire is of a wavy structure.

[0007] Preferably, reinforcing blocks are arranged inside the middle ring.

[0008] Preferably, both ends of the reinforcing block are connected to the reinforcement ring.

[0009] Preferably, there are eight reinforcing blocks, and the eight reinforcing blocks are arranged inside the middle ring and are evenly distributed along its circumferential direction.

[0010] Preferably, a reinforcing ring is further arranged in the middle ring at the middle part of the reinforcing block.

[0011] Preferably, the outer connection part of the edge ring and the reinforcement ring is of an arc-shaped structure.

[0012] Preferably, the sponge is fixed in the cavity by gluing.

[0013] Advantageous Technical Effects of the Utility Model

[0014] 1. By arranging a reinforcement ring inside the edge ring and arranging a sponge in the cavity formed between the two, the utility model can effectively improve the strength of the rim edge, better withstand external impacts, prevent the rim from deforming, thus ensuring driving safety, and the sponge can absorb noise and improve the driving experience.

[0015] 2. One side of the edge ring in contact with the tire is a wavy structure, which can improve the strength and press more forcefully on the tire surface to prevent the tire from falling off. At the same time, the outer connection of the edge ring and the reinforcement ring is an arc-shaped structure, which can reduce resistance, disperse stress, and make the rim edge less likely to be damaged.

[0022] To make the technical solutions of the present invention clearer and more definite to those skilled in the art, the present invention will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present invention are not limited thereto.

[0023] As Figures 1 - 5 shown, an edge-reinforced rim provided in this embodiment includes a middle ring 1. Edge rings 2 are provided at both ends of the middle ring 1. A reinforcement ring 3 is provided inside the edge ring 2. The edge ring 2 and the reinforcement ring 3 are connected end to end to form a cavity 4. A sponge 5 is provided in the cavity 4, which can improve the edge strength of the rim, thereby enhancing the impact resistance, preventing the rim from deforming, ensuring driving safety, and the sponge 5 can absorb noise and improve the driving experience.

[0024] In this embodiment, as Figure 1 shown, one side of the edge ring 2 in contact with the tire is a wavy structure, which can improve the strength and also the contact force to prevent the tire from falling off.

[0025] In this embodiment, as Figure 1 shown, strengthening blocks 6 are provided inside the middle ring 1 to improve the overall strength of the rim and make it less likely to deform and be damaged.

[0026] In this embodiment, as Figure 1As shown, both ends of the reinforcing block 6 are connected to the reinforcing ring 3, which plays a supporting role for the reinforcing ring 3 and keeps the structures of all parts of the rim consistent in stability.

[0027] In this embodiment, as Figure 2 shown, there are eight reinforcing blocks 6. The eight reinforcing blocks 6 are inside the middle ring 1 and are evenly distributed along its circumferential direction, ensuring that the force is evenly dispersed on the rim and further enhancing the load-bearing stability.

[0028] In this embodiment, as Figure 2 shown, a reinforcing ring 7 is further provided in the middle of the reinforcing block 6 inside the middle ring 1 to further improve the rim strength.

[0029] In this embodiment, as Figure 1 shown, the outer connection part between the edge ring 2 and the reinforcing ring 3 is an arc-shaped structure, which can reduce resistance and disperse stress, making the rim edge less likely to be damaged.

[0030] In this embodiment, as Figure 1 shown, the sponge 5 is fixed in the cavity 4 by gluing to prevent the sponge 5 from shifting during driving and ensure the effect.

[0031] In summary, in this embodiment, by providing a reinforcing ring 3 inside the edge ring 2 and arranging a sponge 5 in the cavity 4 formed therebetween, the strength of the rim edge can be effectively improved, better withstand external impacts, prevent the rim from deforming, thus ensuring driving safety. And the sponge 5 can absorb noise and improve the driving experience; the surface of the edge ring 2 in contact with the tire is a wavy structure, which can improve the strength and press more forcefully on the tire surface to prevent the tire from falling off. At the same time, the outer connection part between the edge ring 2 and the reinforcing ring 3 is an arc-shaped structure, which can reduce resistance and disperse stress, making the rim edge less likely to be damaged.
