Description

Technical Field

[0001] The present invention relates to the technical field of motor vehicles, and more specifically, to an automatic inflation and deflation type wheel, and also to an automatic inflation and deflation method for a wheel. Background Art

[0002] During the driving and use of vehicles, due to the complex and ever-changing road conditions, including but not limited to potential obstacles such as sharp stones, broken glass, and nails, it is very easy to get a puncture, which in turn causes the wheel to leak air slowly or quickly. Once the wheel pressure drops, it will not only affect the vehicle's handling performance and increase fuel consumption, but may also cause excessive wear of the wheel due to insufficient air pressure, and even cause a tire blowout in extreme cases, seriously threatening driving safety and the safety of passengers' lives and property. Therefore, regular and detailed inspection and maintenance of the wheels has become an indispensable part of ensuring safe driving of the vehicle.

[0003] When the wheel pressure drops, it is particularly important to add air in time. This can not only quickly restore the normal working state of the wheel, but also effectively avoid problems such as unstable driving and extended braking distance caused by insufficient air pressure, ensuring that the vehicle can continue to drive on the road stably. Especially for vehicles that frequently drive on uneven roads or harsh environments, such as off-road vehicles and pickup trucks, these vehicles face more complex and changeable road conditions, and the test on the wheels is more severe. In addition, such vehicles will also use two wheels side by side to improve their load capacity and road adaptability.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] This embodiment discloses an automatic inflation and deflation type wheel, referring to Figure 1 , Figure 2 and Figure 3 As shown, the wheel hub includes an aluminum alloy material, and the wheel hub includes a ring body 1 and a ring body 2. The inner circumference size of the ring body 2 is mutually adapted to the outer circumference size of the ring body 1, and a portion of the ring body 2 is sleeved on the outer circumference of the ring body 1.

[0038] An end face portion 101 is fixedly connected to the inner periphery of one end of the ring body 1, and an end face portion 201 is fixedly connected to the inner periphery of one end of the ring body 2. The end face portion 101 and the end face portion 201 form a structure protruding toward the inner periphery. The end face portion 101 and the end face portion 201 are pressed against each other to achieve axial positioning, and the end face portion 101 and the end face portion 201 are connected and fixed by a plurality of bolts 3.

[0039] A connection hole is provided at the end surface 101 and the end surface 201, and the bolt 3 passes through the connection holes of the end surface 101 and the end surface 201, and the end surface 101 and the end surface 201 are locked and fixed by the bolt 3 and the nut 301, so that the ring body 1 and the ring body 2 of the wheel hub can be fixedly connected to form an integrated structure. In addition, a countersunk hole 203 is provided on the surface of the end surface 201, and the countersunk hole 203 can accommodate the head of the bolt 3, so that the flatness of the surface can be maintained.

[0040] A sealing ring 102 is fixedly connected to the outer periphery of the ring body 1, and a sealing ring 202 is fixedly connected to the outer periphery of the ring body 2. The wheel is installed between the sealing ring 102 and the sealing ring 202. After the wheel is installed, an annular sealed chamber structure can be formed between the wheel, the ring body 1 and the ring body 2 to prevent air leakage from the wheel body.

[0041] A sealing ring 1 5 is provided between the end surface portion 101 and the end surface portion 201 , and the sealing ring 1 5 can realize a pressure seal between the ring body 1 and the ring body 2 2 .

[0042] Reference Figure 3 As shown, an air inlet hole 106 is provided on the side of the end surface 101 facing away from the end surface 201, and an air guide groove 108 is provided on the outer periphery of the end surface 101. The air guide groove 108 extends to the outside of the ring body 2. The end surface 101 is provided with a connecting hole 107, which is arranged along the radial direction, one end of which is connected to the air inlet hole 106, and the other end of which is connected to the air guide groove 108, so that the air inlet hole 106, the connecting hole 107 and the air guide groove 108 are connected, so that the air inlet hole 106 can be connected to the inner cavity of the wheel, and the wheel can be inflated.

[0043] Furthermore, the automatic inflatable and deflated wheel further comprises an inflating device 9, which comprises an inflating connector 901, which is mounted at the axial center of the wheel hub, and an air guide tube 902 is connected to the inflating connector 901, and an inflating connector 904 is connected to the end of the air guide tube 902, and the inflating connector 904 is mounted to the air inlet hole 106. The inflating device 9 can be used to introduce air into the air inlet hole 106 along the air guide tube 902, and then the required air pressure can be injected into the wheel.

[0044] The inflation device 9 also includes an air tank, an air pump and a valve device. The air pump can be used to inject gas into the air tank. An air pressure detector is also connected to the air pipe 902 to detect the air pressure in the wheel. When the air pressure in the wheel is insufficient, the air in the air tank can be injected into the wheel through the air joint 901 along the air pipe 902 to supplement the air pressure in the wheel. When the air pressure in the wheel is too high, the air in the wheel is partially discharged through the pressure relief valve, thereby achieving wheel pressure relief and maintaining the air pressure in the wheel within the required range.

[0045] Further, refer to Figure 2 , Figure 3 As shown, an axially penetrating air inlet hole 103 is provided at the end surface 101, and an air guide groove 105 is provided on the periphery of the end surface 101. A connecting hole 104 is provided at the end surface 101, and the connecting hole 104 is arranged along the radial direction, with one end connected to the air inlet hole 103 and the other end connected to the air guide groove 105.

[0046] In addition, an axially penetrating air guide hole 204 is provided on the second end surface portion 201, and the air guide hole 204 is connected to the first air inlet hole 103, and a sealing ring 26 is provided between the first end surface portion 101 and the second end surface portion 201. The sealing ring 26 is located at the periphery of the air guide hole 204 and the first air inlet hole 103, and can achieve a sealed connection between the air guide hole 204 and the first air inlet hole 103. When the sealing ring 26 is installed, a sealing groove can be provided at the corresponding position, and the sealing ring 26 can be embedded in the sealing groove, so that the connection and sealing between the two can be achieved.

[0047] Reference Figure 3 As shown, the automatic inflation and deflation wheel also includes a sealing plug 4, which is inserted into the air guide hole 204 and the air inlet hole 103 to achieve sealing of the air guide hole 204 and the air inlet hole 103. The sealing plug 4 can seal the hole connecting the air guide hole 204 and the air inlet hole 103 with the inner cavity of the wheel, thereby achieving the closure of the road channel, and the air can be inflated and deflated into the wheel through the air inlet hole 106.

[0048] This embodiment also discloses another automatic inflation and deflation type wheel. Figure 4 , Figure 5 , Figure 6 , Figure 7 Detailed description.

[0049] In this embodiment, two wheel hubs are provided, and the two wheel hubs are fixedly installed side by side and are roughly symmetrically distributed. The end surface portions 201 of the two wheel hubs are pressed against each other and are fixedly connected, so that two wheels can be installed side by side. The two wheels are respectively an outer wheel and an inner wheel. The outer wheel is located on the outer side of the vehicle, and the inner wheel is located on the inner side of the vehicle. The wheel in this embodiment is suitable for the rear wheel of the vehicle, and can carry a large load to ensure the stability of the vehicle.

[0050] Among them, two side-by-side wheel hubs are provided with two air inlet holes 106, one of which is connected to the air duct 902 through an air charging connector 904, so as to inflate air into the wheel; and the other air inlet hole 106 can be sealed by a sealing plug 8 to avoid air leakage.

[0051] After the two hubs are mounted and fixed to each other, the air guide holes 204 of the two hubs are connected to each other, and the peripheral connection of the two air guide holes 204 is sealed by the sealing ring 3 7. The two air guide holes 204 and the two air inlet holes 103 are coaxial and connected to each other to form a balance channel 12.

[0052] The automatic inflation and deflation wheel in this embodiment further includes a pressure stabilizing device 11, which includes two connection covers 1100, which are respectively arranged at the two ends of the balancing channel 12. The connection cover 1100 is integrally connected with a tubular plug body 1101, which extends into the end of the balancing channel 12 to achieve sealing, thereby enabling the connection cover 1100 to communicate with the air inlet 103.

[0053] In addition, a connecting port 1103 is opened on the outer periphery of the plug body 1101, and the connecting port 1103 is connected to the connecting hole 104, so that the two wheels can pass through the air guide groove 105, the connecting hole 104, the air inlet hole 103, and the balance channel 12, so that the inner cavities of the two wheels can be connected to each other.

[0054] After the two wheels are connected, the air pressure of the wheels can be balanced with each other. When the air pressure of the wheel on one side decreases, the gas in the other wheel can be replenished into the leaking wheel, thereby achieving a basically balanced pressure state for the two wheels.

[0055] Reference Figure 6 , Figure 7As shown, a conical flared portion 1102 is formed at one end of the plug body 1101 toward the middle section of the balancing channel 12, and the flared portion 1102 forms a conical structure. A valve core 13 is slidably connected in the balancing channel 12, and a plurality of through grooves 1309 are provided on the outer periphery of the valve core 13. The through grooves 1309 are arranged along the axial direction of the valve core 13 and pass through to both ends of the valve core 13; the two ends of the valve core 13 can be connected through the through grooves 1309, so that the balancing channel 12 can achieve smooth ventilation.

[0056] Conical portions 1301 are formed at both ends of the valve core member 13, and the conical portions 1301 and the flared portion 1102 are adapted to each other. During the axial sliding process of the valve core member 13, the conical portions 1301 can approach the flared portion 1102, thereby making the conical portions 1301 and the flared portion 1102 abut against each other, thereby achieving sealing at the flared portion 1102.

[0057] The connecting cover 1100 is provided with a piston cavity 1104, and both ends of the valve core member 13 are fixedly connected with a connecting rod 1302, and one end of the connecting rod 1302 away from the valve core member 13 is fixedly connected with a piston part 1303. The piston of the piston part 1303 is connected to the piston cavity 1104, and can slide in the piston cavity 1104. In addition, a support spring 1105 is pressed against the side of the piston part 1303 away from the valve core member 13, and the two ends of the support spring 1105 are respectively pressed between the valve core member 13 and the inner wall surface of the piston cavity 1104, so that the valve core member 13 can be elastically maintained by the support spring 1105. The valve core member 13 can be maintained in a relatively centered position by two support springs 1105, so that the two ends of the valve core member 13 are separated from the flared part 1102, ensuring that the flared part 1102 can be in an open state so that the gas can flow smoothly.

[0058] For example, when the right wheel of two side-by-side wheels suddenly has a flat tire, the air pressure of the right wheel will suddenly decrease, directly approaching the external atmospheric pressure, while the air pressure of the left wheel is still at a higher state. The air pressure of the high-pressure wheel on the right will flow to the wheel on the flat tire side along the balance channel 12. However, due to the excessive pressure difference between the wheels on both sides, the air pressure will push the valve core member 13 to move to the right until the tapered portion 1301 at the right end of the valve core member 13 will abut against the flared portion 1102, thereby achieving a pressure-sealed state at the flared portion 1102, thereby avoiding the situation where the wheel on the left has excessive gas leakage, and still maintaining the left wheel at a higher state, so that one of the two side-by-side wheels can work normally. In the case of a flat tire, the balance channel 12 can be quickly blocked and closed, and the stability of the vehicle can still be basically maintained by one of the two side-by-side wheels.

[0059] Reference Figure 6 , Figure 7 As shown, the valve core component 13 includes two valve core halves 1300 , which are respectively located at the left and right ends of the balance channel 12 , and the two valve core halves 1300 are combined together to form the valve core component 13 .

[0060] The left valve core half body 1300 is fixedly connected with an extension rod 1305, and the right valve core half body 1300 is provided with a second piston chamber 1307. The end of the extension rod 1305 extends into the second piston chamber 1307 and is sealed and slidably connected with the right valve core half body 1300. A guide slide hole 1311 is provided in the right valve core half body 1300, and the extension rod 1305 passes through the guide slide hole 1311 and is sealed and slidably connected with the guide slide hole 1311.

[0061] In addition, the piston in the piston chamber 1307 is connected with a piston part 1306, and the piston part 1306 is fixedly connected to the end of the extension rod 1305. The piston chamber 1307 can be divided into two left and right chambers by the piston part 1306, and the left and right chambers are in a relatively separated and sealed state. Moreover, a linkage spring 1308 is elastically pressed on the right side of the piston part 1306, one end of the linkage spring 1308 presses on the piston part 1306, and the other end presses on the pressure of the right chamber, so that the piston part 1306 can be pushed to the left direction by the linkage spring 1308. Through the elastic action of the linkage spring 1308, the two valve core halves 1300 can be pushed in the direction away from each other, so that the two valve core halves 1300 can be maintained in a structure away from each other. The conical parts 1301 of the two valve core halves 1300 can correspond to the flared parts 1102 on both sides and maintain a state close to each other.

[0062] A through hole 1304 is provided in the center of the left valve core half 1300. The left end of the through hole 1304 passes through the piston part 1303 along the connecting rod 1302 and is connected to the chamber on the left side of the piston chamber 1104. The right end of the through hole 1304 extends along the extension rod 1305 to the piston part 2 1306.

[0063] In addition, an opening 1310 connected to the through hole 1304 is opened on the left side of the piston part 1306, so that the through hole 1304 can be connected to the chamber on the left side of the piston chamber 1307. Gas can be introduced from the piston part 1306 to the opening 1310 through the through hole 1304, and then into the chamber on the left side of the piston chamber 1307. Through other additions in the chamber on the left side of the piston chamber 1307, the piston part 1306 can be pushed to the right relative to the piston chamber 1307, so that the two valve core halves 1300 can approach each other, and the tapered portions 1301 of the two valve core halves 1300 can approach each other.

[0064] In this embodiment, the inflating device 9 further comprises an inflating joint 901, which is installed at the axial center of the wheel hub, and is also connected to a second air guide pipe 903, and a second air guide pipe 905 is connected to the end of the second air guide pipe 903, and the second air guide pipe 905 is connected to the left connection cover 1100, and is in communication with the chamber on the left side of the piston chamber 1104. High-pressure gas can be introduced into the piston chamber 1104 through the second air guide pipe 903, specifically into the chamber on the left side of the piston chamber 1104, and the gas is then introduced into the second piston chamber 1307 through the through hole 1304, so as to adjust the position of the two valve core halves 1300.

[0065] The present embodiment also discloses a method for automatic inflation and deflation of wheels. By adopting the automatic inflation and deflation type wheels as described above, the wheels can be automatically inflated and deflated through the inflation device 9, and when a structure in which two wheels are arranged side by side is adopted, the two wheels can replenish air to each other; and when one of the wheels produces tire protection or a large amount of air leakage, it can also be cut off.

[0066] When the air pressure difference between the left and right wheels is too large, the air pressure of one wheel will push the valve core member 13 to move axially, so that the tapered portion 1301 at one end of the valve core member 13 can block the flared portion 1102 on the corresponding side. When the wheel on the side with low tire pressure rotates during driving, the self-sealing fluid in the wheel will block the punctured part, so that the wheel can return to a basically sealed state again.

[0067] The inflating device 9 can fill the wheel with high-pressure gas to replenish the inner cavity of the wheel. At the same time, the inflating device 9 can pass high-pressure gas into the left chamber of the second piston chamber 1307 through the second air guide pipe 903 and the second inflating joint 905. Under the action of the high-pressure gas, the two valve core halves 1300 will produce relative movement, and the two valve core halves 1300 can approach each other, thereby exerting a force on the two valve core halves 1300 to move toward the middle position of the balance channel 12, exerting a force on the valve core halves 1300 to approach each other, thereby making the tapered portion 1301 of the valve core halves 1300 separate from the flared portion 1102, thereby making the flared portion 1102 recover from a closed state to an open state. Then, the valve core member 13 can open the originally closed flared portion 1102, thereby making the balance channel 12 recover to a connected state, thereby making the inner cavities of the two wheels recover to a connected state. When the inflating device 9 inflates the left wheel, the internal pressure of the two wheels can be connected through the balance channel 12 to restore the pressure balance, so that the two wheels can be inflated and pressure balanced again. Moreover, after the two valve core halves 1300 are close to each other, the distance between the piston part 1303 at both ends of the two valve core halves 1300 will be reduced, so that the pressure of the support spring 1105 on the piston part 1303 will also be reduced, and the pressure between the tapered part 1301 and the flared part 1102 can be reduced, so that the tapered part 1301 and the flared part 1102 can be separated, so as to ensure that the balance channel 12 can be opened to achieve air pressure balance and gas transmission of the two wheels.
