[0027] See Figures 1 - 5, an embodiment of the present utility model provides a wheel, which includes a wheel hub 100, a tire 200 and a valve 300. The tire 200 is assembled on the wheel hub 100, and a tire cavity is formed between the tire 200 and the wheel hub 100. A sealing ring 101 is provided on the outer peripheral surface of the wheel hub 100. A partition 201 is provided on the inner peripheral surface of the tire 200. The partition 201 and the tire 200 are an integral body. The partition 201 cooperates with the sealing ring 101 and divides the tire cavity into a first sub-cavity 202 and a second sub-cavity 203. The valve 300 is used to inflate the first sub-cavity 202 and the second sub-cavity 203. The valve 300 includes a valve outer sleeve 301 and a valve core 302. An air core guiding hole 303 and an inflation hole 304 extending from the air core guiding hole 303 to the outer end are provided inside the valve outer sleeve 301. The valve outer sleeve 301 is provided with a first air outlet hole 305 and a second air outlet hole 306 communicating with the air core guiding hole 303. A sealing surface 307 is provided between the air core guiding hole 303 and the inflation hole 304. The valve core 302 is floatingly assembled in the air core guiding hole 303 and can be located at an open position or a closed position. When the valve core 302 is at the closed position, the valve core 302 abuts against the sealing surface 307, blocks the inflation hole 304 and the air core guiding hole 303, and blocks the first air outlet hole 305 and the second air outlet hole 306. When the valve core 302 is at the open position, the valve core 302 is separated from the sealing surface 307, and conducts the inflation hole 304 with the first air outlet hole 305 and the second air outlet hole 306. The valve 300 is installed on the sealing ring 101. The sealing ring 101 is provided with a third air outlet hole 102 communicating the first air outlet hole 305 with the first sub-cavity 202, and the sealing ring 101 is provided with a fourth air outlet hole 103 communicating the second air outlet hole 306 with the second sub-cavity 203. Wherein, the valve core 302 can automatically return to the closed position under the air pressure in the tire cavity or by setting an elastic member.

[0028] Combined with Figures 1 - 5 , in the technical solution of the present utility model, a partition 201 is provided on the inner peripheral surface of the tire 200, and the tire cavity is divided into a first sub-cavity 202 and a second sub-cavity 203. When one sub-cavity fails, the other sub-cavity can enable the vehicle to continue to drive smoothly. Wherein, the valve core 302 of the valve 300 is a one-way double core, which is respectively connected to the first sub-cavity 202 and the second sub-cavity 203 of the tire 200. When the valve core 302 is at the open position, it can simultaneously inflate the first sub-cavity 202 and the second sub-cavity 203 on both sides through the valve 300; when the valve core 302 is at the closed position, while blocking the inflation hole 304 and the air core guiding hole 303, the valve core 302 blocks the first air outlet hole 305 and the second air outlet hole 306. When the tire cavity on one side is at low pressure, the tire cavity on the other side still maintains normal pressure. The inflation structure of the present utility model is ingeniously designed, more concise, lower in cost, and can better meet the use requirements of multi-cavity tires 200.

[0029] Specifically, refer to Figure 1 、 Figure 2, the wheel hub 100 includes a rim 104 and spokes 105. The rim 104 has a certain width. On one axial edge of the rim 104, there is a first bead 106, and on the other axial edge of the rim 104, there is a second bead 107. A sealing ring 101 is provided on the outer peripheral surface of the rim 104 between the first bead 106 and the second bead 107. The tire 200 includes a first sidewall 204, a second sidewall 205, and a tread 206 between the first sidewall 204 and the second sidewall 205. The tread 206 of the tire 200 is used to directly contact the road surface. The first sidewall 204 and the second sidewall 205 do not contact the ground. The sidewalls mainly work in a flexed state and must withstand large mechanical deformations. The thickness of the sidewalls can be slightly thinner than that of the tread 206. The inner edge of the first sidewall 204 forms a first bead 207, and the inner edge of the second sidewall 205 forms a second bead 208. The first bead 207 cooperates with the first bead 106, and the second bead 208 cooperates with the second bead 107 to assemble the tire 200 on the wheel hub 100, enabling the tire 200 to be firmly fixed on the wheel hub 100 and resist the force that causes the outer tire to separate from the wheel hub 100 during vehicle operation. A partition 201 is provided on the inner peripheral surface of the tread 206 between the first sidewall 204 and the second sidewall 205. The partition 201 cooperates with the sealing ring 101 and divides the tire cavity into a first sub-cavity 202 and a second sub-cavity 203.

[0030] In some embodiments, referring to Figure 1 , the distance between the partition 201 and the first sidewall 204 is equal to the distance between the partition 201 and the second sidewall 205. The partition 201 is located between the two sub-cavities, equivalent to assembling two tires 200 of the same specification.

[0031] Furthermore, referring to Figure 1 、 Figure 2 、 Figure 5 , the sealing ring 101 is provided with a valve mounting hole that extends in the thickness direction of the rim 104. The valve 300 is installed in the valve mounting hole, and the outer end of the valve 300 protrudes from the inner peripheral surface of the wheel hub 100.

[0032] In some embodiments, referring to Figure 5 , the sealing surface 307 is a curved surface, and the valve core 302 has a spherical head that cooperates with the curved surface. The valve core 302 and the sealing surface 307 cooperate through the spherical head and the curved surface, and the cooperation area is larger, which can effectively improve the sealing effect in the closed position.

[0033] In some embodiments, referring to Figure 5 , the valve 300 further includes a cap 307 and an elastic member 308 provided on the back side of the valve core 302. The valve core 302 can abut against the sealing surface 307 under the action of the elastic member 308, and the valve core 302 can automatically return to the closed position under the action of the elastic member 308.

[0034] Further, referring to Figure 4 and Figure 5 , a detachable end cap 309 is provided on the back side of the air nozzle 300 by the elastic member 308. The end cap 309 is hermetically connected to the air nozzle outer sleeve 301. The end cap 309 is used to facilitate the disassembly and assembly of the air core 302 and the elastic member 308 in the air nozzle outer sleeve 301, and at the same time prevent the gas in the tire cavity from leaking through here.

[0035] In some embodiments, referring to Figure 4 and Figure 5 , the air core 302 is provided with a pressing rod 310 extending outward along the inflation hole 304. When it is necessary to actively release the gas in the tire cavity, the pressing rod 310 can be pressed inward into the air nozzle 300. The pressing rod 310 drives the air core 302 to move inward into the air nozzle outer sleeve 301 and separates from the sealing surface 307. The rest of the first sub-chamber 202 and the second sub-chamber 203 can be discharged through the air nozzle 300.

[0036] Further, referring to Figure 4 and Figure 5 , the pressing rod 310 is provided with a limiting boss 311. The hole wall of the inflation hole 304 is provided with a limiting groove that cooperates with the limiting boss 311. The cooperation between the limiting boss 311 and the limiting groove plays a role in circumferential rotation limitation, ensuring the matching accuracy between the air core 302 and the air nozzle outer sleeve 301.

[0037] In some embodiments, referring to Figure 1 and Figure 5 , the sealing ring 101 protrudes toward the inside of the tire cavity. The end face of the sealing ring 101 is provided with a V-shaped groove 106. The end of the partition 201 is provided with a V-shaped flange that cooperates with the V-shaped groove 106. The V-shaped flange and the V-shaped groove 106 cooperate to form a double-sealing structure, ensuring that the gases in the first sub-chamber 202 and the second sub-chamber 203 do not communicate with each other after inflation. When one side is at low pressure, the other side remains at normal pressure. At the same time, the sealing ring 101 that protrudes toward the inside of the tire cavity can also strengthen the rigidity of the wheel hub 100.

[0038] The embodiments of the present invention also provide an automobile, including the wheel in any of the above embodiments.

[0039] In the description of this specification, the description referring to terms such as "example", "embodiment" or "some embodiments" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0040] Certainly, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
