[0046] In the embodiment, the tire body 1 is divided into multiple independent chambers 11, when one chamber 11 leaks, the remaining chambers 11 can maintain normal use, thereby avoiding serious tire burst accidents. Since the valve assembly 2 is arranged on the tire body 1, the valve assembly 2 is provided with multiple valve cores 21, and each valve core 21 is communicated with each chamber 11 through the inflation pipe 3, so that each chamber 11 can be inflated together while ensuring the independence of each chamber 11, and the inflation process is more convenient. Since each chamber 11 is inflated through the valve assembly 2 at the same time, compared with single inflation of each chamber 11, the present scheme makes the air pressure consistency in each chamber 11 better, and guarantees the use performance of the run-flat tire. The inflation pipe 3 can be fixed to the inner side wall of the tire body 1 to prevent the inflation pipe 3 from swinging or falling off during use.

[0047] It can be understood that each chamber 11 is communicated by an independent inflation pipe 3, and part of the inflation pipe 3 may pass through the adjacent other chamber 11 to reach the corresponding chamber 11. At this time, the inflation pipe 3 and the other chamber it passes through are still sealed, and only communicated with the corresponding chamber 11.

[0048] Reference Figure 3 and Figure 4 In the embodiment, the valve assembly 2 further includes an outer sleeve 22, the inner part of the outer sleeve 22 is provided with an inflation cavity 221 and multiple radially penetrating installation grooves 222, each valve core 21 is connected to each installation groove 222, one end of each installation groove 222 is communicated with each inflation pipe 3, and the other end of each installation groove 222 is communicated with the inflation cavity 221.

[0049] Specifically, taking the direction shown in the figure as an example, the outer sleeve 22 can be a substantially cylindrical sleeve, and the inflation cavity 221 is arranged at the upper end of the outer sleeve 22. In the un-inflated state, the inflation cavity 221 is open upward, and the valve core 21 is closed, so it will not leak. When inflating, connect the external air source device to the inflation cavity 221, and open each valve core 21 to inflate. The upper end inlet of each valve core 21 is communicated through the inflation cavity 221, so that each chamber 11 can be inflated at the same air pressure at the same time, improving the efficiency of inflation, and making the air pressure of each chamber 11 balanced, which is beneficial to the use of the run-flat tire. In the embodiment, the outer sleeve 22 is used to integrate multiple valve cores 21, and the inflation cavity 221 can be connected to the external air source device to facilitate inflating each valve core 21 at the same time.

[0050] In the embodiment, the valve core 21 is provided with external threads, the installation groove 222 is provided with internal threads, and the valve core 21 is threadedly connected with the installation groove 222.

[0051] ReferenceFigure 4 The valve assembly 2 further comprises a pressing piece 23 detachably connected with the outer sleeve 22, the pressing piece 23 is capable of abutting against each valve core 21 to simultaneously open each valve core 21, and the pressing piece 23 is capable of separating from each valve core 21 to close each valve core 21. By abutting against each valve core 21 simultaneously through the pressing piece 23, each valve core 21 is opened simultaneously to facilitate simultaneous inflation.

[0052] In some embodiments, the pressing piece 23 can be detached and connected to the air outlet of an external air source device, so that when the external air source device is docked to the valve assembly 2 for inflation, the pressing piece 23 abuts against the valve core 21 to open the valve core 21, and the plurality of valve cores 21 can be inflated simultaneously to inflate each chamber 11 of the run-flat tire simultaneously. Of course, the pressing piece 23 does not block the air outlet of the external air source device, for example, a ring-shaped pressing piece 23 or a gas hole on the pressing piece 23.

[0053] Reference Figure 4 The valve assembly 2 further comprises a cap 24 detachably connected with the outer sleeve 22, and the cap 24 is capable of playing a protective role when connected to the outer sleeve 22. In some embodiments, the top of the cap 24 can be closed, so that the internal valve core 21 can be protected by the cap 24. When inflation is needed, the cap 24 can be removed for inflation.

[0054] Reference Figure 1 and Figure 2 The inner cavity is circumferentially and / or radially divided into a plurality of chambers 11.

For some larger tires, the inner cavity can be divided into two parts in the radial direction, and each part is circumferentially divided into a plurality of chambers 11, for example, a total of eight chambers 11, to improve the run-flat performance. The number of valve cores 21 corresponds to the number of chambers 11, for example, eight chambers 11 are provided with eight valve cores 21. The chambers 11 can be separated by a separator, which can be made of the same rubber material as the tire body, or other materials used to make tires, which are soft, elastic and not easy to break. The inflation pipe 3 can communicate with the corresponding chamber 11 through the separator, and the inflation pipe 3 and the separator are in sealed connection.

[0055] Reference Figure 5The valve core 21 comprises a core seat 211, a core body 212 and an elastic member 213. The core seat 211 is internally provided with a through air passage 2111. The air passage 2111 is internally provided with a first shoulder 2112 and a second shoulder 2113. The core body 212 is arranged through the air passage 2111. The core body 212 is provided with a first protrusion 2121 and a second protrusion 2122 extending in the radial direction. The elastic member 213 is arranged in the air passage 2111 and connected or abuts to the core seat 211 and the core body 212 at both ends. The first protrusion 2121 and the second protrusion 2122 abut to the first shoulder 2112 and the second shoulder 2113 respectively to block the air passage 2111. The core body 212 is blocked in the core seat 211 by the elastic member 213. When inflating is needed, the core body 212 is pressed to push the elastic member 213 to open the air passage 2111, which is convenient for sealing and inflating.

[0056] Specifically, the elastic member 213 can be a compression spring. Taking the direction shown in the figure as an example, the upper end of the compression spring abuts to the lower end of the first protrusion 2121 of the core body 212, and the lower end of the compression spring abuts to the lower end inside the air passage 2111. Under the condition that no external force is applied, the compression spring pushes the core body 212 upward to abut to the core seat 211 to block the air passage 2111, and the valve core 21 is closed. When the core body 212 is subjected to downward pressure, the compression spring is compressed downward, and the first protrusion 2121 and the second protrusion 2122 are separated from the first shoulder 2112 and the second shoulder 2113. At this time, the valve core 21 is opened, and each chamber 11 can be inflated by an external high-pressure gas source device.

When charging is not needed, the cap 24 without the charging port 241 can be replaced, and the crimping piece 23 does not need to be arranged in the cap 24. That is, the cap 24 with the crimping piece 23 and the charging port 241 is designed for convenience of charging, and the ordinary cap 24 can be replaced after charging is completed.

[0060] Reference Figure 4 In the embodiment, the crimping piece 23 is annular, the valve core 21 is arranged in the outer sleeve 22 in a same height, and the crimping piece 23 corresponds to the position of the valve core 21 in the vertical direction.
