Description

Technical Field

[0001] The present invention relates to the technical field of vehicle tire inflation, and in particular to a movable air supply system and a vehicle. Background Art

[0002] Tires are important supporting and gripping parts of vehicles during driving. Correct tire pressure can ensure that the contact area between the tire and the ground is moderate, providing good grip, thereby enhancing the braking performance and handling stability of the vehicle. Too low tire pressure will affect the contact between the tire and the ground, reduce the braking effect, increase the risk of skidding, and threaten driving safety. Too low tire pressure may also cause tire overheating and accelerated wear.

[0003] During driving, if a tire is punctured by a sharp object such as a nail, screw or glass fragment, it will cause slow air leakage and insufficient tire pressure, and if the valve is damaged or the seal is poor, it will cause the tire pressure to drop. Insufficient tire pressure will increase vehicle fuel consumption, reduce tire life, and even cause a risk of tire blowout. The vehicle is prone to instability during driving, increasing the risk of traffic accidents. Summary of the invention

[0026] When a vehicle is driving, there are usually sharp objects on the road such as nails that pierce the tire and cause air leakage, or the wheel valve is not sealed tightly and causes air leakage, which will make the vehicle unstable during driving and increase the risk of traffic accidents. In order to solve the problem of how to supply air to the tire during driving, a movable air supply system is proposed. Figure 3As shown, a movable air supply system may include a bearing assembly 01 and an air supply assembly 02. The bearing assembly 01 may include an outer ring unit 11, an inner ring unit 12, and a rolling unit 13. The outer peripheral wall of the outer ring unit 11 may be rollingly connected with the inner peripheral wall of the inner ring unit 12 through the rolling unit 13, and the rolling connection may reduce friction and extend the service life of the bearing assembly 01. The inner ring unit 12 may drive the outer ring unit 11 to rotate through the rolling unit 13. The inner ring unit 12 may rotate relative to the outer ring unit 11 along its own circumferential direction, so that the inner ring unit 12 of the bearing may support the rotating parts in the mechanical device and transmit force and motion when rotating.

[0027] The air supply assembly 02 may include a first air supply unit 21, a second air supply unit 22, a first adapter unit 23, and a second adapter unit 24. The first adapter unit 23 may include a first sealing ring 231, a second sealing ring 232, and a connecting ring disk 233. The inner peripheral wall of the first sealing ring 231 may abut against a portion of the outer peripheral wall of the outer ring unit 11, which may improve the sealing performance of the first sealing ring 231 and effectively prevent gas leakage from the gap between the two. The outer peripheral wall of the first sealing ring 231 may be detachably connected to a portion of the inner peripheral wall of the connecting ring disk 233, making it more convenient and quick to install and replace the first sealing ring 231, thereby reducing maintenance costs. The inner peripheral wall of the second sealing ring 232 may abut against a portion of the outer peripheral wall of the outer ring unit 11, which may make the two closely connected and improve the sealing effect of the second sealing ring 232. The outer peripheral wall of the second sealing ring 232 may be detachably connected to a portion of the inner peripheral wall of the connecting ring disk 233, which may facilitate the installation and separate replacement of the second sealing ring 232 and reduce maintenance costs. One side of the first sealing ring 231 can be in contact with one side of the second sealing ring 232, so that the two are closely connected to eliminate the gap between them and enhance the sealing effect. The first sealing ring 231, the second sealing ring 232, and the outer ring unit 11 can surround and form a first cavity, and one end of the first air supply unit 21 can pass through the outer ring unit 11 to communicate with the first cavity. In this way, the gas output by the vehicle's own air source can pass through the first air supply unit 21 and pass through the outer ring unit 11 into the first cavity. One side of the connecting ring disk 233 can be detachably connected to the inner ring unit 12, which is convenient for separate disassembly and replacement and also convenient for installation. There is grease in the first cavity for lubrication, which reduces the wear caused by the rotation of the outer ring unit 11 and the first sealing ring 231 and the second sealing ring 232, thereby extending the service life of the first sealing ring 231 and the second sealing ring 232. When the vehicle is running, the rotation of the wheel drives the inner ring unit 12 to rotate, thereby causing the connecting ring disk 233 to rotate. The connecting ring disk 233, the first sealing ring 231, and the second sealing ring 232 can surround and form a second cavity. The second cavity can be communicated with the first cavity through the second air supply unit 22. The second adapter unit 24 can be communicated with the second cavity. The gas that is convenient to enter the first cavity can enter the second cavity through the second air supply unit 22. When the gas enters the first cavity, since the inner circumferential wall of the first sealing ring 231 abuts against part of the outer circumferential wall of the outer ring unit 11, and the inner circumferential wall of the second sealing ring 232 abuts against part of the outer circumferential wall of the outer ring unit 11, the first sealing ring 231 and the second sealing ring 232 have a sealing effect, and the grease in the first cavity will not be blown away by the gas and remains in the first cavity, and can be used for lubrication between the outer ring unit 11 and the first sealing ring 231 and the second sealing ring 232. Then, the gas that has entered the second cavity can supply air to the tire through the second adapter unit 24.This can ensure that the tires can be supplied with air while the vehicle is driving, so that the vehicle can maintain stability during driving and avoid traffic accidents caused by insufficient tire pressure while the vehicle is driving.

[0028] In some embodiments, Figure 2As shown, the first sealing ring 231 may include a first body 2311, a first lip 2313, a second lip 2314, and a third lip 2315. The second sealing ring 232 may include a second body 2321, a fourth lip 2323, a fifth lip 2324, and a sixth lip 2325. The first body 2311 may be spaced apart from the second body 2321, and the spaced apart arrangement may form a spaced apart area, and grease may be placed in the spaced apart area for lubrication. At the same time, the spaced apart arrangement may play a supporting role so that the first sealing ring 231 and the second sealing ring 232 maintain their shapes. One end of the first lip 2313 may be fixedly connected to the inner circumferential wall of the first body 2311, and the other end may extend in a direction away from the second body 2321 and close to the outer ring unit 11, and the end of the first lip 2313 away from the first body 2311 may abut against the outer circumferential wall of the outer ring unit 11. In this way, foreign matter can be effectively prevented from entering the interval area during the driving of the vehicle, and when the first sealing ring 231 and the outer ring unit 11 rotate relative to each other, the end of the first lip 2313 away from the first body 2311 can still be in close contact with the outer peripheral wall of the outer ring unit 11 to prevent grease leakage. The second lip 2314 can be spaced apart from the first lip 2313, and the second lip 2314 can further prevent foreign matter from entering the interval area. One end of the second lip 2314 can be fixedly connected to the inner peripheral wall of the first body 2311, and the other end can extend in a direction close to the second body 2321 and close to the outer ring unit 11. The end of the second lip 2314 away from the first body 2311 can be in contact with the outer peripheral wall of the outer ring unit 11. In this way, the end of the second lip 2314 away from the first body 2311 can be in closer contact with the outer peripheral wall of the outer ring unit 11, effectively preventing the grease used for lubrication in the first cavity from leaking. The third lip 2315 can be spaced apart from the second lip 2314. One end of the third lip 2315 can be fixedly connected to the side of the first body 2311 close to the second body 2321, and the other end can extend in the direction close to the second body 2321. When the gas enters the first cavity, the airflow forms a swirl to squeeze the grease into the space between the third lip 2315 and the second lip 2314, and the grease will not be blown out of the first cavity. At the same time, it is convenient for the grease to wet the second lip 2314, reducing the wear caused by the rotation of the outer ring unit 11 and the first sealing ring 231. One end of the fourth lip 2323 can be fixedly connected to the inner peripheral wall of the second body 2321, and the other end can extend in the direction away from the first body 2311 and close to the outer ring unit 11. The end of the fourth lip 2323 away from the second body 2321 can abut against the outer peripheral wall of the outer ring unit 11. In this way, foreign matter can be effectively prevented from entering the first cavity, and when the second sealing ring 232 and the outer ring unit 11 rotate relative to each other, the end of the fourth lip 2323 away from the second body 2321 can still continue to be tightly abutted against the outer wall of the outer ring unit 11, effectively preventing the leakage of grease used for lubrication in the first cavity.The fifth lip 2324 can be spaced apart from the fourth lip 2323, and the fifth lip 2324 can further prevent foreign matter from entering the first cavity. One end of the fifth lip 2324 can be fixedly connected to the inner circumferential wall of the second body 2321, and the other end can extend in a direction close to the first body 2311 and close to the outer ring unit 11. The end of the fifth lip 2324 away from the second body 2321 can abut against the outer circumferential wall of the outer ring unit 11. In this way, the end of the fifth lip 2324 away from the second body 2321 can abut more closely against the outer circumferential wall of the outer ring unit 11, effectively preventing the grease used for lubrication in the first cavity from leaking. The sixth lip 2325 can be spaced apart from the fifth lip 2324, and one end of the sixth lip 2325 can be fixedly connected to a side of the second body 2321 close to the first body 2311, and the other end can extend in a direction close to the first body 2311, and the sixth lip 2325 can abut against the third lip 2315. The first cavity is formed between the second lip 2314, the third lip 2315, the fifth lip 2324, the sixth lip 2325 and the outer ring unit 11. When the gas enters the first cavity, the airflow squeezes most of the grease into the space between the sixth lip 2325 and the fifth lip 2324, reducing the leakage of grease in the first cavity. At the same time, the grease wets the fifth lip 2324, reducing the wear caused by the rotation of the outer ring unit 11 and the second sealing ring 232.

[0029] In some embodiments, the second air supply unit 22 may include a first vent 221 and a second vent 222. The first vent 221 may penetrate the third lip 2315, and the second vent 222 may penetrate the sixth lip 2325, so that the first cavity can be connected to the second cavity through the first vent 221 and the second vent 222. The gas entering the first cavity can pass through the first vent 221 and the second vent 222 to enter the second cavity. The first vent 221 may be arranged at intervals along the circumference of the third lip 2315. The second vent 222 may be arranged at intervals along the circumference of the sixth lip 2325. The interval arrangement of multiple holes can increase the gas flow rate through the multiple holes, thereby improving the efficiency of tire inflation.

[0030] In some embodiments, the first sealing ring 231 may further include a first extension portion 2316, and the second sealing ring 232 may further include a second extension portion 2326. One end of the first extension portion 2316 may be fixedly connected to a side of the third lip portion 2315 close to the outer ring unit 11, and the other end may extend in a direction close to the outer ring unit 11. One end of the first extension portion 2316 close to the outer ring unit 11 may be spaced apart from the outer peripheral wall of the outer ring unit 11, one end of the second extension portion 2326 may be fixedly connected to a side of the sixth lip portion 2325 close to the outer ring unit 11, and the other end may extend in a direction close to the outer ring unit 11. One end of the second extension portion 2326 close to the outer ring unit 11 may be spaced apart from the outer peripheral wall of the outer ring unit 11, and one side of the first extension portion 2316 may abut against one side of the second extension portion 2326. The gas entering the first cavity is easily diverted from the abutment between one side of the first extension 2316 and one side of the second extension 2326 to generate a swirl flow and compress the second lip 2314 and the fifth lip 2324 to achieve a better sealing effect, while further preventing the grease from being blown out of the first cavity, and better guiding the grease to lubricate the second lip 2314, the fifth lip 2324 and the outer ring unit 11. The side of the first extension 2316 away from the second extension 2326 can be smoothly connected to the side of the third lip 2315 close to the outer ring unit 11, and the side of the second extension 2326 away from the first extension 2316 can be smoothly connected to the side of the sixth lip 2325 close to the outer ring unit 11. The smooth transition connection allows the gas to form a swirl flow better, thereby forming a better seal and reducing the leakage of grease. One end of the first vent 221 close to the first cavity can be arranged in the smooth transition connection area between the first extension 2316 and the third lip 2315, and one end of the second vent 222 close to the first cavity can be arranged in the smooth transition connection area between the second extension 2326 and the sixth lip 2325. In this way, the gas can be better discharged from the first cavity to prevent grease leakage. In this way, the gas can flow more smoothly and stably, and the smooth transition connection can better guide the flow direction of the gas, thereby improving the efficiency of inflating the tire.

[0031] In some embodiments, the ends of the second lip 2314 and the fifth lip 2324 close to the outer ring unit 11 can both adopt arc transition, which can prevent the grease from being blown out of the first cavity by the gas, and can guide the grease to lubricate the second lip 2314, the fifth lip 2324 and the outer ring unit 11 along the arc transition direction.

[0032] In some embodiments, the first sealing ring 231 may further include a first deformation cavity 2312, and the second sealing ring 232 may further include a second deformation cavity 2322. The first deformation cavity 2312 and the second deformation cavity 2322 may be annular cavities, the first deformation cavity 2312 may be disposed in the first body 2311, and the second deformation cavity 2322 may be disposed in the second body 2321. The reaction force generated by the first deformation cavity 2312 and the second deformation cavity 2322 being squeezed and deformed can make the third lip 2315 and the sixth lip 2325 abut more firmly, so that they better fit the sealing surface, thereby improving the sealing effect.

[0033] In some embodiments, the connecting ring disc 233 may include a connecting disc body 2331, a fourth channel 2332, and a connecting portion 2333. The inner peripheral wall of the connecting disc body 2331 may abut against the outer peripheral wall of the first sealing ring 231 and the outer peripheral wall of the second sealing ring 232, respectively, so that the first lip 2313, the second lip 2314, the fourth lip 2323, and the fifth lip 2324 may abut against the outer ring unit 11 more firmly, and the first sealing ring 231 and the second sealing ring 232 may be prevented from falling off. One end of the connecting portion 2333 may be fixedly connected to one side of the connecting disc body 2331, and the other end may be detachably connected to the inner ring unit 12, so as to facilitate the installation and maintenance of the connecting ring disc 233. When the wheel rotates during the driving of the vehicle, the inner ring unit 12 also rotates. The connection between the connecting portion 2333 and the inner ring unit 12 can drive the connecting ring disc 233 to rotate, so as to facilitate the delivery of gas to the second adapter unit 24 during the rotation of the wheel. One end of the fourth channel 2332 can be connected to the second air supply unit 22, and the other end can pass through the connecting disc 2331 and the connecting part 2333 in sequence to communicate with the second adapter unit 24. When the gas reaches the first cavity, it can enter the second cavity through the second air supply unit 22, and then pass through the connecting disc 2331, the connecting part 2333 and the second adapter unit 24 in sequence along the fourth channel 2332, and finally supply the gas to the tire for inflation.

[0034] In other embodiments, the outer ring unit 11 may include an outer ring body 111 and an outer ring flange 112. The outer ring body 111 provides a stable frame so that the rolling unit 13 can roll smoothly. The outer ring flange 112 can usually be fixed to the vehicle body or other components by bolts or other fasteners to ensure that it can be firmly installed on the vehicle. The inner ring unit 12 may include an inner ring body 121 and an inner ring flange 122. The inner ring flange 122 may be detachably connected to the connecting portion 2333, which is convenient for installation and separate removal and replacement of the connecting portion 2333 or the inner ring flange 122. The inner ring body 121 can be used to bear loads, and when the inner ring flange 122 rotates, it can drive the connecting ring disc 233 to rotate through the connecting portion 2333.

[0035] In some embodiments, Figure 1 As shown, the first gas supply unit 21 may include a first channel 211, a second channel 212, and a third channel 213. The first channel 211, the second channel 212, and the third channel 213 may be connected in sequence. The first channel 211, the second channel 212, and the third channel 213 may all be arranged in the outer ring unit 11. Since the space around the outer ring unit 11 is compact and the wall thickness of the outer ring body 111 is thin, the first channel 211 may be arranged in the outer ring flange 112. Due to the influence of the first sealing ring 231 and the second sealing ring 232, the third channel 213 may extend in the direction close to the inner ring unit 12, so as to facilitate the gas delivery. The end of the third channel 213 away from the second channel 212 may be connected to the first cavity, so that the gas may flow to the first cavity along the third channel 213 in the direction away from the second channel 212.

[0036] In some embodiments, the distance from the side of the third channel 213 close to the inner ring unit 12 to the central axis of the inner ring unit 12 is smaller than the distance from the side of the second channel 212 close to the inner ring unit 12 to the central axis of the inner ring unit 12. This allows the third channel 213 to form a groove for buffering, which is used to guide the airflow to pass through the connection in a smoother path, thereby helping to buffer the gas at the connection between the second channel 212 and the third channel 213, thereby reducing fluid resistance, ensuring the air delivery volume, and thus improving the air delivery efficiency of the tire. At the same time, it can act as a buffer to prevent grease in the first cavity from flowing into the second channel 212.

[0037] In some embodiments, a vehicle may include a vehicle body, a wheel, and an air supply pump. The air supply pump may be arranged on the vehicle body to provide gas to the wheel. The inner ring unit 12 may be detachably connected to the vehicle body, and the outer ring unit 11 may be detachably connected to the wheel. The detachable connection facilitates the replacement and maintenance of the outer ring unit 11, which may reduce maintenance time and cost. The air supply pump may be connected to the first cavity through the first air supply unit 21, and the end of the second adapter unit 24 away from the connecting ring disc 233 may be connected to the wheel. In this way, the gas output by the air supply pump during the rotation of the wheel enters the first cavity through the first air supply unit 21, and then enters the second cavity after passing through the second air supply unit 22, and finally the gas may enter the second adapter unit 24 from the second cavity to inflate the wheel.

[0038] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present disclosure.
