The buffer structure can be set as an annular elastic body surrounded by at least two arc-shaped elastic parts as required, and the at least two arc-shaped elastic parts are spliced and surrounded to form an annular structure; the arc-shaped elastic parts can be arranged into one, two, three and four parts according to the requirement. The buffer structure 400 is provided with a concave-convex surface 410 near one side of the supporting component 300, and the concave-convex surface 410 is matched with the second supporting disk 330. The buffer structure 400 may be coupled to a corresponding number of the second support plates 330 by means of vulcanization bonding or the like. The two adjacent arc-shaped elastic parts can be directly connected by vulcanization bonding and the like.

It should be noted that the buffer structure 400 may be a single annular structure. The provision of the cushioning structure 400 as at least two separate pieces (preferably integrally cast or vulcanization molded) allows for better assembly and attachment of the cushioning structure 400. Cushioning structure 400 may be made of rubber, thermoplastic elastomer, or other suitable materials.

In a second aspect, embodiments of the present application provide a vehicle including a vehicle body and the non-pneumatic tire described above, the non-pneumatic tire being detachably mounted on the vehicle body.

Based on the embodiment of the application, the vehicle with the non-pneumatic tire is lower in cost and higher in safety. The assembly structure 100 is provided in cooperation with a vehicle, and the whole non-pneumatic tire can be mounted on the vehicle by the assembly structure 100, and different assembly structures 100 can be provided adaptively according to different vehicle types. The reinforcing structure 200 may increase the overall strength of the non-pneumatic tire, and the reinforcing structure 200 may carry the support assembly 300 and the buffer structure 400. The support assembly 300 can provide a supporting force for the non-pneumatic tire, and after the non-pneumatic tire is mounted on the vehicle, the support assembly 300 can provide a supporting force, and particularly, the support assembly is supported by a plurality of support units 310, and the support units 310 can provide a certain elastic supporting force by the support portions 311 with arc structures, so that the vehicle can better run on a bumpy road surface, and the vibration of the vehicle is reduced. The cushion structure 400 may further provide cushioning vibration reduction capabilities for a non-pneumatic tire. Also, the plurality of support units 310 of the present application may exist alone, and after only a portion of the support units 310 is damaged, the replacement cost of repair may be reduced by partially replacing the portion of the support units 310. Moreover, since the non-pneumatic tire does not have the pneumatic tube of the pneumatic tire, when the non-pneumatic tire is pricked by a sharp object, the cushioning structure 400 can be only pierced and pricked on the supporting unit 310, and the supporting unit 310 cannot lose functions due to partial breakage, so that safe running of the vehicle can be ensured. The non-pneumatic tire in the embodiment of the application has the beneficial effects of lower cost and higher safety.

The vehicle body comprises a vehicle body and a vehicle frame, wherein the vehicle body is arranged above the vehicle frame, the vehicle body can be enclosed into a passenger cabin, the vehicle frame is used for supporting the vehicle body, a rotating shaft is arranged on the vehicle frame, and a non-pneumatic tire is detachably arranged on the rotating shaft. The engine of the vehicle can directly or indirectly drive the rotating shaft to rotate so as to drive the non-pneumatic tire to rotate, and when the non-pneumatic tire contacts the ground, the whole vehicle can be driven to run along the ground through friction force.

The same or similar reference numerals in the drawings of the present embodiment correspond to the same or similar components; in the description of the present application, it should be understood that, if there is an azimuth or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc., based on the azimuth or positional relationship shown in the drawings, this is for convenience of description and simplification of the description, but does not indicate or imply that the apparatus or element to be referred must have a specific azimuth, be constructed and operated in a specific azimuth, and thus terms describing the positional relationship in the drawings are merely used for illustration and are not to be construed as limitations of the present patent, and that the specific meaning of the terms described above may be understood by those of ordinary skill in the art according to the specific circumstances.

The foregoing description of the preferred embodiment of the present utility model is not intended to limit the utility model to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
