[0030] The tire 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0031] Referring toFigures 1-2 As shown, the tire 100 according to an embodiment of the present invention may include: a wheel hub 10, an outer tire 30, and an inner tire 20.

[0032] Specifically, the wheel hub 10 is used to support the outer tire 30 and the inner tire 20, buffer external impacts, and improve the driving performance of the tire 100. Both the outer tire 30 and the inner tire 20 are mounted on the wheel hub 10. The inner tire 20 and the wheel hub 10 define a first chamber 21, and a second chamber 31 is defined between the outer tire 30 and the inner tire 20. The outer tire 30 has the same function as a conventional tire. The outer tire 30 contacts the ground and can achieve position movement. The inner tire 20 is equivalent to a tire embedded in a conventional tire, that is, the inner tire 20 is a tire embedded in the outer tire 30.

[0033] When the tire 100 is inflated once, the inner tire 20 and the outer tire 30 are inflated respectively to make the pressures in the first chamber 21 and the second chamber 31 reach the specified pressures to achieve the load-bearing and running functions. Among them, the inflation method of the tire 100 can be inflation through a pump, an air pump, etc.; the pressure in the first chamber 21 can be greater than, equal to, or less than the pressure in the second chamber 31, that is, the first chamber 21 and the second chamber 31 can be inflated according to one tire pressure value or two different tire pressure values to meet different requirements, and these are all within the protection scope of the present invention. The tire 100 can be used for machinery such as vehicles, and the present invention does not limit this.

[0034] When the load is small, such as when running without load, the pressure on the outer tire 30 is small, and thus the deformation of the outer tire 30 is small. At this time, the outer tire 30 does not contact the inner tire 20. The performance of the tire 100 is affected by the outer tire 30 and the pressure, and the pressure in the second chamber 31 and the performance of the outer tire 30 can enable the tire 100 to achieve the load-bearing and running functions. Therefore, the tire 100 can meet the performance requirements of running without load. When the load is large, such as when running at half load or full load, the pressure on the outer tire 30 is large, and thus the deformation of the outer tire 30 is large, causing the outer tire 30 to contact the inner tire 20. And as the pressure increases, the inner tire 20 deforms. At this time, the performance of the tire 100 is affected by the outer tire 30, the inner tire 20, and the weight of the vehicle, and the pressure in the first chamber 21, the pressure in the second chamber 31, the performance of the outer tire 30, and the performance of the inner tire 20 can enable the tire 100 to achieve the load-bearing and running functions. Therefore, the tire 100 can meet the performance requirements of half load and full load. The performance requirements of the tire 100 under other load conditions are similar to the above situations and will not be elaborated here.

[0035] Therefore, inflating the tire 100 once can meet the performance requirements of different loads such as running without load, at half load, and at full load, without the need to replace tires 100 with different performances to adapt to different loads, which has good economy and high user comfort.

[0036] Meanwhile, a cut-off valve 40 is provided between the first chamber 21 and the second chamber 31. The cut-off valve 40 has a connected state in which the first chamber 21 and the second chamber 31 are connected and a blocked state in which the connection is blocked. When the tire 100 is operating normally, the cut-off valve 40 can be in the blocked state to meet the performance requirements for different load bearings. Among them, the cut-off valve 40 can be provided at parts such as the inner tire 20 and the wheel hub 10, or a component for installing the cut-off valve 40 can be additionally provided, and these are all within the protection scope of the present invention.

[0037] When the pressure in the second chamber 31 decreases and the pressure of the outer tire 30 is insufficient, the cut-off valve 40 can be controlled to be in the connected state, so that the first chamber 21 is connected to the second chamber 31, thereby supplementing gas from the first chamber 21 to the second chamber 31 to increase the pressure of the second chamber 31. When the pressure of the second chamber 31 reaches a preset value, the cut-off valve 40 can be controlled to be in the blocked state to keep the pressure of the outer tire 30 constant and make the tire 100 run more stably. Among them, the preset value can be set according to requirements.

[0038] When the outer tire 30 has a blowout, the cut-off valve 40 is controlled to be in the blocked state to block the first chamber 21 and the second chamber 31, so as to keep the pressure of the first chamber 21 temporarily unchanged. At this time, the inner tire 20 can instantly take over the tire 100 and keep running safely, effectively reducing the safety hazards caused by the blowout of the outer tire 30, reducing the incidence of safety accidents, and improving the running safety of the tire 100.

[0039] According to the tire 100 of the embodiment of the present invention, after inflation, it can meet the performance requirements for different load bearings, has good economy, and the user's comfort is relatively high. At the same time, when the tire 100 is operating normally, if the pressure of the second chamber 31 decreases, gas can be supplemented from the first chamber 21 to the second chamber 31 to increase the pressure of the second chamber 31, keep the pressure of the tire 100 relatively constant, strengthen the running stability of the tire 100, and when the outer tire 30 has a blowout, the inner tire 20 can instantly take over the tire 100 and keep running safely, effectively reducing the incidence of safety accidents and improving the running safety of the tire 100.

[0040] When inflating the tire 100, the current pressure of the tire 100 can be known through an inflation device, etc. For example, in some embodiments, the inflation device includes a pressure gauge. If the pressure of the first chamber 21 is less than the pressure of the second chamber 31, the pressure of the second chamber 31 will squeeze the inner tire 20 inward and deform the inner tire 20 until the pressure of the first chamber 21 is equal to the pressure of the second chamber 31. Therefore, after the inflation of the tire 100 is completed, the pressure of the first chamber 21 is greater than or equal to the pressure of the second chamber 31.

[0041] In some embodiments of the present invention, such as Figure 2As shown, the pressure in the first chamber 21 is higher than the pressure in the second chamber 31. Specifically, when inflating the tire 100, it is required that the final pressure value in the first chamber 21 after inflation is higher than the final pressure value in the second chamber 31. Then, when the outer tire 30 deforms, the inner tire 20 will inhibit the deformation of the outer tire 30, and the greater the load, the greater the force of the inner tire 20 to inhibit the deformation of the outer tire 30, enhancing the ability of the tire 100 to adapt to heavy loads and improving the practicality of the tire 100. Moreover, when the pressure in the second chamber 31 decreases, the on-off valve 40 is controlled to be in a connected state. Then, under the pressure difference that the pressure in the first chamber 21 is higher than the pressure in the second chamber 31, the gas in the first chamber 21 enters the second chamber 31 with a higher efficiency, thereby accelerating the pressure increase speed in the second chamber 31 and further improving the practicality of the tire 100.

[0042] In some embodiments of the present invention, as Figure 2 shown, the tire 100 further includes a pressure detector for detecting the pressure in the second chamber 31. Among them, the pressure detector can be arranged at any position such as the on-off valve 40, the outer tire 30, the inner tire 20, the wheel hub 10, etc., as long as it can detect the pressure in the second chamber 31.

[0043] When the detection result of the pressure detector is lower than the preset pressure value, the on-off valve 40 is in a connected state. After inflation, when the pressure in the first chamber 21 is higher than that in the second chamber 31, in the connected state, the pressure in the first chamber 21 is higher and the pressure in the second chamber 31 is lower. Connecting the first chamber 21 and the second chamber 31 can make the gas in the first chamber 21 enter the second chamber 31, increasing the pressure in the second chamber 31 to improve the running performance of the tire 100. When the pressure in the second chamber 31 increases to the preset pressure value, the on-off valve 40 is in a blocked state to keep the pressure of the outer tire 30 constant and improve the running stability of the tire 100.

[0044] When the detection result of the pressure detector is not lower than the preset pressure value, the on-off valve 40 is in a blocked state. At this time, the pressure in the second chamber 31 is sufficient to achieve the load-bearing and running functions. Blocking the first chamber 21 and the second chamber 31 can maintain the pressure difference between the first chamber 21 and the second chamber 31 to meet the performance requirements for different load-bearing.

[0045] The pressure detector detects the pressure in the second chamber 31 more precisely, making the state switching of the on-off valve 40 more reliable and improving the running reliability of the tire 100. Among them, the preset pressure value can be set according to the detection results of the actual operation of the tire 100, and the present invention does not limit this. As long as the tire 100 can operate normally when the pressure in the second chamber 31 is at the preset pressure value. It should be noted that the state switching of the on-off valve 40 can be automatically switched or controlled by other structures such as the pressure detector, etc., and these are all within the protection scope of the present invention.

[0046] In some embodiments, as Figure 2 shown, when the detection result of the pressure detector is normal pressure, the on-off valve 40 is in a blocked state. At this time, the pressure in the second chamber 31 is a large pressure, and it can be considered that the outer tire 30 is in a flat tire state. The blocked state of the on-off valve 40 can block the first chamber 21 and the second chamber 31, maintain the pressure in the first chamber 21, and further enable the inner tire 20 to take over the tire 100 and maintain safe driving when the outer tire has a flat tire, improving the safety of the operation of the tire 100.

[0047] In some embodiments of the present invention, the on-off valve 40 includes a valve body, a plugging member, and an elastic member. Specifically, the valve body has a valve passage, the plugging member is used to open and block the valve passage, the elastic member is disposed between the plugging member and the valve body, and is used to apply a driving force for driving the plugging member to block the valve passage. The plugging member can open the valve passage when the difference between the pressure value in the first chamber 21 and the pressure value in the second chamber 31 is greater than the driving force. Here, the difference refers to the value obtained by subtracting the pressure value in the second chamber 31 from the pressure value in the first chamber 21.

[0048] After inflation is completed, the pressure in the first chamber 21 is higher than or equal to the pressure in the second chamber 31. During use, affected by factors such as weather and sealing reliability, the pressure in the second chamber 31 will decrease, and the difference between the pressure value in the first chamber 21 and the pressure value in the second chamber 31 will increase. For example, in winter, the tire 100 deforms due to thermal expansion and contraction, or when it is observed that the tire 100 has a significant air loss before driving, resulting in a decrease in the pressure of the outer tire 30.

[0049] When the difference is less than or equal to the driving force, the elastic member applies a driving force to the plugging member to block the valve passage, and at this time, the on-off valve 40 is in a blocked state.

[0050] When the difference is greater than the driving force, the gas in the first chamber 21 squeezes the plugging member to open the valve passage, making the on-off valve 40 in a connected state, and then enabling the gas in the first chamber 21 to enter the second chamber 31, increasing the pressure in the second chamber 31 to improve the operating performance of the tire 100. When the pressure in the second chamber 31 increases to the point where the difference is less than or equal to the driving force, the elastic member applies a driving force to the plugging member to block the valve passage to keep the pressure of the outer tire 30 constant and improve the stability of the operation of the tire 100.

[0051] In some embodiments, the plugging or opening of the plugging member can also be manually opened by moving the plugging member to replenish air to the outer tire 30, and the present invention does not limit this.

[0052] In some embodiments, the driving force of the elastic member can be adjusted. The elastic member can be an elastic object such as a spring. For example, the driving force can be adjusted by adjusting the deformation amount of the spring.

[0053] In some embodiments of the present invention, as Figure 2 shown, the tire 100 further includes a first inflatable tube 50. The first inflatable tube 50 is in communication with the first chamber 21 and is used to inflate the first chamber 21. When inflating the tire 100, the first chamber 21 can be inflated through the first inflatable tube 50, so as to obtain a certain tire pressure value, and the operation is relatively convenient. The first inflatable tube 50 can be an air nozzle, an inflation valve, a pipe with a switching valve, etc. The first inflatable tube 50 can be provided on components such as the wheel hub 10 and the outer tire 30. The present invention does not limit this, as long as the first inflatable tube 50 can be in communication with the first chamber 21 and the first chamber 21 can be inflated through the first inflatable tube 50.

[0054] Furthermore, in some embodiments, as Figure 2 shown, the tire 100 further includes a second inflatable tube 60. The second inflatable tube 60 is in communication with the second chamber 31 and is used to inflate the second chamber 31. When inflating the tire 100, the second chamber 31 can be inflated through the second inflatable tube 60, so as to obtain a certain tire pressure value, and the operation is relatively convenient. The second inflatable tube 60 can be an air nozzle, an inflation valve, a pipe with a switching valve, etc. The second inflatable tube 60 can be provided on components such as the wheel hub 10 and the outer tire 30. The present invention does not limit this, as long as the second inflatable tube 60 can be in communication with the second chamber 31 and the second chamber 31 can be inflated through the second inflatable tube 60.

[0055] The first chamber 21 is inflated by the first inflatable tube 50, and the second chamber 31 is inflated by the second inflatable tube 60. Therefore, after inflating the tire 100 through the first inflatable tube 50 and the second inflatable tube 60, a tire pressure value or different tire pressure values can be obtained, and the inflation operation is convenient and the feasibility is relatively high.

[0056] Of course, in some embodiments, the second inflatable tube 60 can also be omitted, and the inflation of the first chamber 21 and the second chamber 31 can be achieved by the cooperation of the first inflatable tube 50 and the on-off valve 40, so as to reduce the number of components and lower the cost.

[0057] In some embodiments, the on-off valve 40 penetrates through the inner tire 20. Then, the on-off valve 40 is in direct contact with both the first chamber 21 and the second chamber 31 at the same time. In the connected state, the pressure increase efficiency of the second chamber 31 through the on-off valve 40 is higher, and there is no need to additionally provide components for installing the on-off valve 40, making the structure of the tire 100 more compact and improving the operating performance of the tire 100.

[0058] In some embodiments including a first charging tube 50 and a second charging tube 60, as Figure 2 shown, the on-off valve 40 connects the first charging tube 50 and the second charging tube 60. Then, there is no need to additionally open a channel connecting the first chamber 21 and the second chamber 31 for the tire 100. The gas flow between the first chamber 21 and the second chamber 31 can be realized through the first charging tube 50 and the second charging tube 60, which is beneficial to improving the structural compactness of the tire 100 and enhancing the running performance of the tire 100.

[0059] In some embodiments, as Figure 2 shown, the on-off valve 40 connects the first charging tube 50 and the second charging tube 60, and the on-off valve 40 is located outside the first chamber 21 and the second chamber 31. Then, the external structure of the on-off valve 40 is not affected by the tire pressure, which is beneficial to improving the structural stability and service life of the tire 100 and is conducive to enhancing the accuracy of the state switching of the on-off valve 40. At the same time, the on-off valve 40 is located outside the first chamber 21 and the second chamber 31, which is convenient for overhauling or replacing the on-off valve 40.

[0060] In some embodiments of the present invention, as Figure 2 shown, the first charging tube 50 penetrates through the wheel hub 10, and the second charging tube 60 penetrates through the wheel hub 10 and the outer tire 30, which is convenient for inflating the first chamber 21 and the second chamber 31 respectively from the wheel hub 10, and the operation is relatively convenient.

[0061] In some embodiments, the second charging tube 60 penetrates through the wheel hub 10 or the outer tire 30. Then, the position of the second charging tube 60 and the second chamber 31 is relatively compact, and the inflation speed of the second chamber 31 through the second charging tube 60 is relatively fast, which improves the inflation efficiency of the tire 100.

[0062] The vehicle according to the embodiment of the present invention includes the tire 100 according to the embodiment of the present invention. Since the tire 100 according to the embodiment of the present invention has the above beneficial technical effects, the vehicle according to the embodiment of the present invention can adapt to the performance requirements of different loads after inflation, has better economy, and the user's comfort is relatively high. At the same time, when the tire 100 is running normally, if the pressure of the second chamber 31 decreases, the first chamber 21 can supply gas to the second chamber 31 to increase the pressure of the second chamber 31 and keep the pressure of the tire 100 relatively constant, enhancing the running stability of the tire 100. Moreover, when the outer tire 30 bursts, the inner tire 20 can instantaneously take over the tire 100 and keep running safely, effectively reducing the incidence of safety accidents and improving the running safety of the tire 100.

[0063] Next, the tire 100 according to a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the following description is only illustrative and should not be construed as a limitation of the invention.

[0064] AsFigures 1-2 As shown, a tire 100 according to a specific embodiment of the present invention is for a vehicle. The tire 100 includes a wheel hub 10, an inner tire 20, an outer tire 30, a first inflatable tube 50, a second inflatable tube 60, a on-off valve 40, and a pressure detector.

[0065] The inner tire 20 is disposed inside the outer tire 30. The inner tire 20 and the wheel hub 10 define a first chamber 21, and a second chamber 31 is defined between the outer tire 30 and the inner tire 20. The first inflatable tube 50 passes through the wheel hub 10, and the second inflatable tube 60 passes through the wheel hub 10 and the outer tire 30. The on-off valve 40 connects the first inflatable tube 50 and the second inflatable tube 60, and the on-off valve 40 is located outside the first chamber 21 and the second chamber 31. The pressure detector is used to detect the pressure value of the second chamber 31.

[0066] When inflating the tire 100, the first chamber 21 is inflated through the first inflatable tube 50, and the second chamber 31 is inflated through the second inflatable tube 60, so that two different tire pressure values can be obtained, and the pressure of the first chamber 21 is higher than that of the second chamber 31. When the tire 100 is running normally, the on-off valve 40 is in a blocked state, and the tire 100 can adapt to the performance requirements of different loads.

[0067] If the pressure detector detects that the pressure value of the second chamber 31 is not lower than the preset pressure value, at this time the outer tire 30 has sufficient pressure and the tire 100 is in a normal running state, then the on-off valve 40 is in a blocked state, separating the first chamber 21 from the second chamber 31. Among them, the preset pressure value can be set according to requirements.

[0068] If the pressure detector detects that the pressure value of the second chamber 31 is lower than the preset pressure value, at this time the outer tire 30 has insufficient pressure, then the on-off valve 40 switches to a connected state, and gas is supplemented from the first chamber 21 to the second chamber 31, which is beneficial to improving the stability of the overall vehicle performance and the driving safety of the user. When the pressure detector detects that the pressure value of the second chamber 31 reaches the preset pressure value, the on-off valve 40 switches to a blocked state to stop inflating the second chamber 31, keeping the pressure of the outer tire 30 constant and making the tire 100 run more stably.

[0069] If the pressure detector detects that the pressure value of the second chamber 31 is equal to the large pressure value, at this time it can be considered that the outer tire 30 has a flat tire, and the on-off valve 40 switches to a blocked state, separating the first chamber 21 from the second chamber 31 to maintain the pressure difference between the pressure of the first chamber 21 and the large pressure, so that the inner tire 20 can instantly take over the tire 100 and keep the vehicle running safely, effectively reducing the incidence of safety accidents and improving the driving safety of the user.

[0070] The other components and operations of the tire 100 and the vehicle according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.

[0071] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense.
