[0019] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment:

[0021] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0022] A non-inflatable foamed tire includes a main body 1. A hub 2 is provided inside the main body 1. A protective layer 4 is provided outside the hub 2 inside the main body 1. A shock-absorbing layer 6 is provided outside the hub 2 inside the protective layer 4. A buffer layer 7 is provided outside the hub 2 inside the shock-absorbing layer 6. A connecting layer 8 is provided outside the hub 2 inside the buffer layer 7. When the non-inflatable foamed tire is put into use, the main body 1 is connected to the hub 2 through the connecting layer 8. The main body 1 and the protective layer 4 have high strength and strong wear resistance, and can better withstand various force abrasions during the driving process of the tire. The shock-absorbing layer 6 and the buffer layer 7 protect the hub 2, offset part of the force on the hub 2, extend the service life of the tire, make the driving more stable and comfortable, improve the driving safety, and improve the stability and overall performance of the tire.

[0023] Furthermore, the materials of the main body 1 and the protective layer 4 are both rubber. A plurality of bead wires 3 are provided at equal intervals outside the protective layer 4 inside the main body 1. Rubber has the advantages of high hardness, good wear resistance, good anti-aging ability, good impact resistance, shock absorption and cold resistance. It can effectively resist external friction and will not be affected by external temperature changes. Therefore, the main body 1 has high strength and strong wear resistance, and good appearance performance. The bead wires 3 further strengthen the strength of the main body 1, make the tire more durable, and extend the service life.

[0024] Among them, a plurality of elastic blocks 41 are provided at equal intervals between the main body 1 and the shock-absorbing layer 6 inside the protective layer 4. A cavity 42 is opened inside the elastic block 41. When the non-inflatable foamed tire is put into use, the cavity 42 can absorb part of the impact load and improve the stability of the main body 1.

[0025] Secondly, a fixing block 5 is provided between every two groups of elastic blocks 41. A through hole 51 is formed in the outer side of the fixing block 5. When the non-pneumatic foamed tire is put into use, with the rotation of the tire, friction will cause the tire to heat up. When air passes through the through hole 51, part of the heat is taken away, avoiding damage to the tire caused by high temperature and extending the service life.

[0026] Furthermore, the material of the shock-absorbing layer 6 is a polyester fiber porous air cushion, and the material of the buffer layer 7 is cord rubber. The polyester fiber air cushion has the characteristics of light weight, durability, tear resistance, etc. Cord rubber has good heat conductivity, aging resistance, fatigue resistance and low heat generation, and can maintain certain physical and mechanical properties at high temperatures. The shock-absorbing layer 6 can effectively reduce the impact of vibration on the vehicle, and the buffer layer 7 can absorb part of the pressure transmitted from the direction of the hub 2, protecting the hub 2 and making the driving more stable and comfortable, improving the driving safety.

[0027] Furthermore, a small bump belt 13 is provided on the outer side of the main body 1. Twill patterns 12 are provided on both sides of the small bump belt 13 on the outer side of the main body 1. A plurality of groups of grooves 11 are provided at equal intervals at one end of the twill pattern 12 away from the small bump belt 13 on the outer side of the main body 1. When the non-pneumatic foamed tire is put into use, the small bump belt 13, the twill pattern 12 and the grooves 11 can all increase the surface friction of the main body 1, so that the tire has a better grip effect, making the driving more stable and comfortable and improving the driving safety.

[0028] Furthermore, a bracket 21 is provided inside the hub 2. A plurality of groups of through holes 22 are provided at equal intervals on the outer side of the bracket 21. Mounting holes 23 are provided between the plurality of groups of through holes 22 on the outer side of the bracket 21. When the non-pneumatic foamed tire is put into use, the hub 2 is connected to the vehicle through the mounting holes 23. The design of the through holes 22 reduces the weight of the tire, makes the tire lighter, and also improves the heat dissipation effect. The bracket 21 makes the structure of the tire more stable, improves the strength of the tire, and extends the service life of the tire.

[0029] In this embodiment, the implementation scenario is specifically as follows: During actual use, when the non-inflatable foam tire is put into use, the main body 1 is connected to the wheel hub 2 through the connecting layer 8, and the wheel hub 2 is connected to the vehicle through the mounting holes 23. The materials of the main body 1 and the protective layer 4 are both rubber, so that the main body 1 and the protective layer 4 have high strength and strong wear resistance, can better withstand various stress and wear during the driving process of the tire, and have good appearance performance. The bead wire 3 further strengthens the strength of the main body 1, makes the tire more durable, and extends the service life. The cavity 42 can absorb part of the impact load and improve the stability of the main body 1. When air passes through the through hole 51, part of the heat is taken away, avoiding damage to the tire caused by high temperature and extending the service life. The material of the shock-absorbing layer 6 is a polyester fiber porous air cushion, which can effectively reduce the impact of vibration on the vehicle. The material of the buffer layer 7 is cord rubber, which can absorb part of the pressure transmitted from the direction of the wheel hub 2, protecting both the wheel hub 2 and making the driving smoother and more comfortable, improving the driving safety. The small bump belt 13, the twill 12 and the groove 11 can all increase the surface friction of the main body 1, thus making the tire's grip effect better, making the driving smoother and more comfortable, improving the driving safety, improving the stability and overall performance of the tire. The design of the perforation 22 reduces the weight of the tire, makes the tire lighter, and also improves the heat dissipation effect. The bracket 21 makes the structure of the tire more stable, improves the strength of the tire, and extends the service life of the tire. Compared with the existing non-inflatable foam tire, the present utility model can improve the overall practicality of the non-inflatable foam tire through the design.

[0030] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
