Wherein, when the second rotating member is located at the first inflation position, the communication hole communicates with the air vent groove. When the second rotating member is located at the second inflation position, the communication hole is disposed opposite to the hole wall of the mounting hole and is covered by the hole wall of the mounting hole.

[0005] In an exemplary embodiment of this application, the second rotating member includes a rotating section, a fixed section, a first blocking portion and a second blocking portion. The first blocking portion is located inside the inner cavity of the rotating section.

The second blocking portion is located inside the inner cavity of the fixed section. The second blocking portion is connected to the cavity wall of the inner cavity of the fixed section and moves synchronously with the fixed section. When the second rotating member is located at the first inflation position, the orthographic projection area of the first blocking portion and the second blocking portion along the axial direction of the second rotating member is equal to the orthographic projection area of the inner cavity along the axial direction of the second rotating member. When the second rotating member is located at the second inflation position, the orthographic projection area of the first blocking portion and the second blocking portion along the axial direction of the second rotating member is smaller than the orthographic projection area of the inner cavity along the axial direction of the second rotating member.

[0006] In an exemplary embodiment of the present application, the rotating section has a first opening, the first blocking portion is disposed at the first opening, the fixed section has a second opening, the second blocking portion is disposed at the second opening, and both the first opening and the second opening are located at the connection between the fixed section and the rotating section; the distance between the first blocking portion and the second blocking portion along the axis of the second rotating member is equal to 0.

[0007] In an exemplary embodiment of the present application, when the second rotating member is in the first inflation position, the positive projection of the first blocking portion along the axis of the second rotating member is in contact with the positive projection of the second blocking portion along the axis of the second rotating member, and they do not overlap.

[0008] In an exemplary embodiment of the present application, the rotating section and the fixed section are within the mounting hole, the outer diameter of the rotating section is equal to the outer diameter of the fixed section, and is equal to the inner diameter of the mounting hole.

[0009] In an exemplary embodiment of the present application, the second rotating member further includes a limiting section, the limiting section is connected to the end of the rotating section away from the fixed section, and the outer diameter of the limiting section is greater than the outer diameter of the rotating section and greater than the outer diameter of the first rotating member.

[0010] In an exemplary embodiment of the present application, the ventilation groove has a ventilation end and a closed end along the axis of the first rotating member, the closed end is located on one side of the limiting section, and the ventilation end is located on one side of the fixed section; the communication hole is provided corresponding to between the closed end and the ventilation end, and the ventilation end is communicated with the outer tire of the tire.

[0011] In an exemplary embodiment of the present application, the inflation structure further includes an end cover portion and an elastic seal, the end cover portion is connected to the second rotating member, and the end cover portion is provided with an air inlet hole communicating with the inner cavity; the elastic seal elastically abuts against the inner cavity and seals the air inlet hole.

[0012] The second aspect of the present application discloses a wheel structure, including a rim, a tire, and the inflation structure as described above, and the inflation structure is passed through the rim and communicated with the tire.

[0013] The third aspect of the present application discloses a vehicle, including a gas source device and the wheel structure as described above, and the gas source device is connected to the wheel structure.

[0014] The solution of the present application has the following beneficial effects:

[0015] In an embodiment of the present application, when the inflation structure is installed on a wheel, since the first rotating member is provided with a mounting hole, an air vent groove communicating with the outer tire of the tire is recessed in the hole wall of the mounting hole, and the second rotating member is rotatably connected in the mounting hole. The second rotating member is provided with an inner cavity and a communication hole communicating with the inner cavity, and the inner cavity communicates with the inner tube of the tire. Therefore, when the second rotating member is in the first inflation position, the communication hole communicates with the outer tire through the air vent groove, and the inner cavity communicates with the inner tube, so that the inflation structure can inflate the outer tire and the inner tube to maintain the tire pressure of the outer tire and the inner tube; when the second rotating member is in the second inflation position, the communication hole is disposed opposite to the hole wall of the mounting hole and is covered by the hole wall of the mounting hole, so that the inflation structure can only inflate the inner tube, which is beneficial to improving the inflation rate of the inner tube.

[0016] Therefore, when the outer tire is damaged and the inner tube needs to be quickly inflated to support the continued use of the outer tire, the second rotating member needs to be rotated to the second inflation position, and the communication hole is covered by the hole wall of the mounting hole, so that the inflation structure can inflate the inner tube more quickly, and then use the inner tube to support the damaged outer tire to continue to be used, avoiding replacing the tire.

[0033] The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation of the present application.

[0034] As Figures 1 to 10 shown, this embodiment provides an inflation structure for a wheel, including: a first rotating member 1 and a second rotating member 2. The first rotating member 1 is inserted through the rim 5 of the wheel. The first rotating member 1 is provided with a mounting hole 101, and a ventilation groove 102 is recessed in the hole wall of the mounting hole 101. The ventilation groove 102 communicates with the inside of the outer tire 61 of the tire 6. The second rotating member 2 is rotatably connected in the mounting hole 101. The second rotating member 2 is provided with an inner cavity 201 and a communication hole 202 communicating with the inner cavity 201. The inner cavity 201 communicates with the inside of the inner tube 62 of the tire 6.

[0035] Furthermore, the second rotating member 2 has a first inflation position and a second inflation position that can be switched with each other in the mounting hole 101. When the second rotating member 2 is in the first inflation position, the communication hole 202 communicates with the ventilation groove 102. When the second rotating member 2 is in the second inflation position, the communication hole 202 is disposed opposite to the hole wall of the mounting hole 101 and is covered by the hole wall of the mounting hole 101.

[0036] In this embodiment, when the inflation structure is installed on the wheel, since the first rotating member 1 is provided with an installation hole 101, and the inner wall of the installation hole 101 is recessed with a ventilation groove 102 communicating with the outer tire 61 of the tire 6, and the second rotating member 2 is rotatably connected in the installation hole 101, the second rotating member 2 is provided with an inner cavity 201 and a communication hole 202 communicating with the inner cavity 201, and the inner cavity 201 communicates with the inner tube 62 of the tire 6. Therefore, when the second rotating member 2 is in the first inflation position, the communication hole 202 communicates with the outer tire 61 through the ventilation groove 102, and the inner cavity 201 communicates with the inner tube 62, so that the inflation structure can inflate the outer tire 61 and the inner tube 62 to maintain the tire pressure of the outer tire 61 and the inner tube 62; when the second rotating member 2 is in the second inflation position, the communication hole 202 is disposed opposite to the inner wall of the installation hole 101 and is covered by the inner wall of the installation hole 101, so that the inflation structure can only inflate the inner tube 62, which is beneficial to improving the inflation rate of the inner tube 62.

[0037] Therefore, when the outer tire 61 is damaged and the inner tube 62 needs to be quickly inflated to support the continued use of the outer tire 61, the second rotating member 2 needs to be rotated to the second inflation position, and the communication hole 202 is covered by the inner wall of the installation hole 101, so that the inflation structure can inflate the inner tube 62 more quickly, and then the damaged outer tire 61 can be supported by the inner tube 62 to continue to be used, avoiding replacing the tire 6.

[0038] Combined with Figures 3 to 5 As shown, the second rotating member 2 includes a rotating section 21, a fixed section 22, a first blocking portion 23 and a second blocking portion 24. The first blocking portion 23 is located in the inner cavity 201 of the rotating section 21, and the first blocking portion 23 is connected to the inner wall of the inner cavity 201 of the rotating section 21 and moves synchronously with the rotating section 21; the second blocking portion 24 is located in the inner cavity 201 of the fixed section 22, and the second blocking portion 24 is connected to the inner wall of the inner cavity 201 of the fixed section 22 and moves synchronously with the fixed section 22.

[0039] In this embodiment, the rotating section 21 is rotatably connected to the fixed section 22, the inner cavity 201 of the fixed section 22 communicates with the inner tube 62, and the communication hole 202 is located in the rotating section 21, that is, the rotating section 21 can rotate relative to the first rotating member 1 along the axial direction of the installation hole 101 to change the positions of the communication hole 202 and the ventilation groove 102.

[0040] Further, when the rotating section 21 is in the first inflation position, the orthographic projection area of the first blocking portion 23 and the second blocking portion 24 along the axial direction of the second rotating member 2 is equal to the orthographic projection area of the inner cavity 201 along the axial direction of the second rotating member 2; when the rotating section 21 is in the second inflation position, the orthographic projection area of the first blocking portion 23 and the second blocking portion 24 along the axial direction of the second rotating member 2 is smaller than the orthographic projection area of the inner cavity 201 along the axial direction of the second rotating member 2.

[0041] In this embodiment, when the rotating section 21 is in the first inflation position, the first barrier portion 23 and the second barrier portion 24 have a certain blocking effect on the gas inflating the inner tube 62. The first barrier portion 23 and the second barrier portion 24 can reduce the inflation rate of the inflation structure to the inner tube 62 when the communication hole 202 communicates with the ventilation groove 102 and the outer tire 61 is inflated, so as to ensure the normal use of the outer tire 61; when the rotating section 21 is in the second inflation position, the communication hole 202 does not communicate with the ventilation groove 102, and the first barrier portion 23 and the second barrier portion 24 need to provide a channel for inflating the inner tube 62, and increase the inflation rate of the inflation structure to the inner tube 62, so as to ensure that the inner tube 62 can support the damaged outer tire 61 to continue to be used.

[0042] It should be understood that when the outer tire 61 is not damaged and can be used normally, the inflation structure does not need to inflate the inner tube 62, and only needs to inflate the outer tire 61 to maintain the tire pressure of the outer tire 61; when the outer tire 61 is damaged and the inner tube 62 needs to support the normal use of the outer tire 61, the inflation structure does not need to inflate the outer tire 61, and only needs to inflate the inner tube 62, and the inner tube 62 can be used to maintain the normal use of the outer tire 61.

[0043] Combined Figures 3 to 5 As shown, the rotating section 21 has a first opening 203, the first barrier portion 23 is arranged at the first opening 203, the fixed section 22 has a second opening 204, the second barrier portion 24 is arranged at the second opening 204, and both the first opening 203 and the second opening 204 are located at the connection between the fixed section 22 and the rotating section 21; the axial distance between the first barrier portion 23 and the second barrier portion 24 along the second rotating member 2 is equal to 0.

[0044] It should be understood that the axial distance between the first barrier portion 23 and the second barrier portion 24 along the second rotating member 2 is not exactly equal to 0, and can be close to 0, that is, a certain error is allowed.

[0045] In this embodiment, the axial distance between the first barrier portion 23 and the second barrier portion 24 along the second rotating member 2 is equal to 0, so that when the rotating section 21 is in the first inflation position, the first barrier portion 23 and the second barrier portion 24 can be completely attached along the axis of the second rotating member 2, so as to ensure that the first barrier portion 23 and the second barrier portion 24 can completely isolate the inner cavity 201 of the rotating section 21 and the inner cavity 201 of the fixed section 22, and all the gas is used to inflate the outer tire 61 to maintain the tire pressure of the outer tire 61.

[0046] It should be understood that since the axial distance between the first blocking portion 23 and the second blocking portion 24 along the second rotating member 2 is equal to 0, the first blocking portion 23 and the second blocking portion 24 can completely isolate the inner cavity 201 of the rotating section 21 and the inner cavity 201 of the fixed section 22. Therefore, no gap is formed between the first blocking portion 23 and the second blocking portion 24 to connect the first opening 203 and the second opening 204, and gas will not inflate the inner tube 62 through the path of the first opening 203, the gap between the first blocking portion 23 and the second blocking portion 24, and the second opening 204, which is beneficial to improving the inflation rate of the outer tire 61.

[0047] Combined with Figure 4 As shown, when the second rotating member 2 is in the first inflation position, the positive projection of the first blocking portion 23 along the axis of the second rotating member 2 is in contact with the positive projection of the second blocking portion 24 along the axis of the second rotating member 2 and does not overlap.

[0048] In this embodiment, both the first blocking portion 23 and the second blocking portion 24 are semi-circular structures. When the second rotating member 2 is in the first inflation position, the first blocking portion 23 and the second blocking portion 24 together can completely enclose the inner cavity 201, so that when the inflation structure inflates the outer tire 61, it will not inflate the inner tube 62; when the second rotating member 2 is in the second inflation position, the positive projections of the first blocking portion 23 and the second blocking portion 24 along the axis of the second rotating member 2 overlap, and the overlapping positive projection area of the first blocking portion 23 and the second blocking portion 24 is half of the inner cavity 201 of the rotating section 21 or the inner cavity 201 of the fixed section 22, which is beneficial to improving the inflation rate of the inflation structure for the inner tube 62. Furthermore, when the outer tire 61 is damaged, the inflation time of the inner tube 62 is reduced to ensure that the outer tire 61 can be quickly used again.

[0049] In this embodiment, the inner diameter of the inner cavity 201 of the rotating section 21, the inner diameter of the inner cavity 201 of the fixed section 22, the diameter of the first blocking portion 23, and the diameter of the second blocking portion 24 are all equal to ensure that the first blocking portion 23 and the second blocking portion 24 can isolate the inner cavity 201 of the rotating section 21 and the inner cavity 201 of the fixed section 22.

[0050] In this embodiment, combined with Figure 1 and Figure 4 As shown, the rotating section 21 and the fixed section 22 are in the mounting hole 101. The outer diameter of the rotating section 21 is equal to the outer diameter of the fixed section 22 and is equal to the inner diameter of the mounting hole 101, so that the rotating section 21 and the fixed section 22 of the second rotating member 2 can be smoothly passed through the first rotating member 1 without other installation tools, which is convenient for the installation of the inflation structure.

[0051] Combined with Figure 1 and Figure 4As shown, the second rotating member 2 further includes a limiting section 25. The limiting section 25 is fixedly connected to one end of the rotating section 21 away from the fixed section 22. The outer diameter of the limiting section 25 is greater than the outer diameter of the rotating section 21 and greater than the outer diameter of the first rotating member 1.

[0052] In this embodiment, the outer diameter of the limiting section 25 is greater than the outer diameter of the rotating section 21, and the outer diameter of the limiting section 25 is greater than the outer diameter of the first rotating member 1, so that the limiting section 25 has a limiting function on the first rotating member 1, and the limiting section 25 can limit the installation position of the first rotating member 1 on the second rotating member 2. When the second rotating member 2 is axially inserted into the first rotating member 1 along the mounting hole 101, the first rotating member 1 can abut against the limiting section 25, preventing the second rotating member 2 from passing through one end of the first rotating member 1 and then passing out from the other end of the first rotating member 1, which affects the installation of the inflation structure.

[0053] In addition, the outer diameter of the limiting section 25 is greater than the outer diameter of the first rotating member 1, that is, the outer diameter of the limiting section 25 is greater than the diameters of the mounting hole 101 and the ventilation groove 102, so as to close one side of the ventilation groove 102 close to the limiting section 25 and prevent the gas for inflating the tire 6 from leaking.

[0054] It should be understood that since the gas for inflating the tire 6 may leak from one side of the ventilation groove 102 close to the limiting section 25, affecting the inflation rate of the tire 6, therefore, the outer diameter of the limiting section 25 should be greater than the diameters of the mounting hole 101 and the ventilation groove 102, and one side of the ventilation groove 102 close to the limiting section 25 is closed by the limiting section 25 to prevent the inflating gas from leaking.

[0055] Combined with Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, the ventilation groove 102 has a ventilation end 102a and a closed end along the axial direction of the first rotating member 1. The closed end is located on one side of the limiting section 25, and the ventilation end 102a is located on one side of the fixed section 22; the communication hole 202 is provided corresponding to between the closed end and the ventilation end 102a, and the ventilation end 102a is communicated with the outer tire 61 of the tire 6.

[0056] In this embodiment, the communication hole 202 is located in the rotating section 21, and the first rotating member 1 is sleeved on the rotating section 21. The communication hole 202 is located between the closed end and the ventilation end 102a, so that the communication hole 202 can be communicated with the outer tire 61 of the tire 6 through the ventilation end 102a of the ventilation groove 102 and inflate the outer tire 61 of the tire 6 to ensure the inflation rate of the tire 6 and reduce the inflation time of the tire 6.

[0057] Combined with Figure 3 and Figure 4As shown, the inflatable structure further includes an end cover portion 3 and an elastic seal 4. The end cover portion 3 is connected to the limiting section 25, and the end cover portion 3 is provided with an air inlet hole 301 communicating with the inner cavity 201; the elastic seal 4 elastically abuts against the inner cavity 201 and seals the air inlet hole 301.

[0058] In this embodiment, the end cover portion 3 is detachably connected to one end of the limiting section 25 away from the rotating section 21. When the end cover portion 3 is detached from the limiting section 25, the elastic seal 4 can be installed into the inner cavity 201 from one end of the limiting section 25 away from the rotating section 21; when the end cover portion 3 is connected to the limiting section 25, the end cover portion 3 and the limiting section 25 move synchronously, and the elastic seal 4 can elastically abut against the inner cavity 201 to close the air inlet hole 301.

[0059] In this embodiment, as shown in combination with Figure 4 As shown, the elastic seal 4 includes an elastic member 41 and a seal member 42. The seal member 42 is connected to the elastic member 41. The elastic member 41 is located in the inner cavity 201 of the limiting section 25 and the inner cavity 201 of the rotating section 21. The seal member 42 is in contact with the end cover portion 3. The elastic member 41 elastically abuts between the seal member 42 and the first barrier portion 23 and drives the seal member 42 to move along the axial direction of the inner cavity 201 to close or open the air inlet hole 301.

[0060] It should be understood that the diameter of the seal member 42 should be greater than the diameter of the air inlet hole 301 to ensure that the seal member 42 can seal the air inlet hole 301; the diameter of the seal member 42 should be less than the diameter of the inner cavity 201 to ensure that when the tire 6 is inflated, the gas can enter the tire 6 from the gap between the seal member 42 and the inner cavity 201.

[0061] For example, the seal member 42 is a steel ball, an iron ball, a steel block, etc.; the elastic member 41 is a spring, a rubber block, etc.

[0062] In this embodiment, the seal member 42 is a steel ball and the elastic member 41 is a spring. The side of the end cover portion 3 close to the limiting section 25 is provided with an installation groove 302. The installation groove 302 communicates with the air inlet hole 301. The installation groove 302 is used to install the steel ball to ensure that the steel ball can completely seal the air inlet hole 301.

[0063] Specifically, when the gas source device is connected to the hole wall of the air inlet hole 301, if the air pressure at the air inlet hole 301 is greater than the air pressure in the tire 6, that is, when the tire 6 needs to be inflated, the gas of the gas source device will push the steel ball and compress the spring, and then the gas will flow into the inner cavity 201 through the gap around the steel ball and finally enter the tire 6; if the air pressure at the air inlet hole 301 is less than the air pressure in the tire 6, that is, when the tire 6 inflation is completed, the spring will return to its original state and push the steel ball to seal the air inlet hole 301.

[0064] As shown in combination with Figures 7 to 10As shown, this embodiment provides a wheel structure, including a rim 5, a tire 6, and the above-mentioned inflation structure. The inflation structure is passed through the rim 5 and communicated with the tire 6.

[0065] In this embodiment, in combination with Figure 8 As shown, the wheel structure further includes a nut 7. The nut 7 is sleeved on the first rotating member 1 and connected to the rim 5 to realize the installation of the inflation structure on the rim 5.

[0066] In this embodiment, in combination with Figure 9 and Figure 10 As shown, the tire 6 includes a tire cover 61 and an inner tube 62. The tire cover 61 is sleeved on the rim 5, and the inner tube 62 is located between the tire cover 61 and the rim 5 and closely adheres to the surface of the rim 5. When the first rotating member 1 is passed through the rim 5, the air vent groove 102 of the first rotating member 1 is communicated with the tire cover 61 for inflating the tire cover 61; the inner cavity 201 of the second rotating member 2 is connected to the inner tube 62 for inflating the inner tube 62.

[0067] For example, the tire cover 61 is made of materials such as natural rubber or synthetic rubber with good wear resistance and safety; the inner tube 62 is made of materials such as natural rubber or butyl rubber with good elasticity.

[0068] In this embodiment, the inner tube 62 is of an annular structure, and the wall thickness of the inner tube 62 is 3 - 5 mm.

[0069] The installation steps of the above-mentioned wheel structure are as follows: First, install the inner tube 62 on the inner wall of the rim 5 and adjust the position of the inner tube 62 to ensure that the inflation structure can be aligned with the installation position on the rim 5; then, fix the inflation structure on the rim 5 through the nut 7; finally, install the tire cover 61 on the rim 5 through the tire disassembly and assembly machine of the tire 6.

[0070] This embodiment also provides a vehicle, including a gas source device and the above-mentioned wheel structure. The gas source device is connected to the wheel structure.

[0071] In this embodiment, after the gas source device is communicated with the air inlet hole 301, it is possible to select the object to be inflated according to the situation of the tire cover 61. By rotating the limiting section 25 to drive the rotating section 21 to rotate, the inflation structure respectively opens the air channels connected to the tire cover 61 or the inner tube 62, so that the tire pressure of the tire cover 61 or the inner tube 62 reaches the tire pressure required for the vehicle to travel.

[0072] In addition, when the outer tire 61 is punctured by a sharp object, it is first necessary to remove the sharp object from the inside of the outer tire 61, and then inflate the inner tire 62 through the inflation structure so that the tire pressure of the inner tire 62 is the same as that of the other three tires 6 of the vehicle, and finally the outer tire 61 can be used continuously. After inflating the inner tire 62 by rotating the inflation structure, the inner tire 62 can support the damaged outer tire 61 to continue to be used, avoiding traffic accidents caused by air leakage of the outer tire 61, and the operation is convenient and fast, so as to reduce the time and effort required to replace the spare tire 6.
