Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a tire inflation system and a vehicle. Background Technology

[0002] With the widespread adoption of automobiles, most families now own a car. Tire pressure is a crucial checkpoint during car maintenance, as it significantly impacts safe driving. When a car is not undergoing maintenance, if tires leak air due to slow deflation, punctures, or other reasons, they need to be inflated promptly to avoid potential safety hazards.

[0003] Chinese patent CN220682340U discloses a tire inflation terminal, including an air storage / deflation assembly and an inflation assembly. The air storage / deflation assembly includes an air tank, an air intake device and an air delivery device connected to the air tank. The air intake device is connected to the inflation assembly to achieve automatic inflation, and the air delivery device is connected to the tire to achieve inflation and / or deflation. The inflation assembly includes an air storage container, a compressor and an inflation device connected to the air storage container, and the inflation device is connected to the air storage / deflation assembly to achieve automatic inflation.

[0004] However, the aforementioned Chinese patent has some drawbacks, specifically: the gas storage tank and the gas filling component in the gas storage and release assembly need to be designed and manufactured separately, which results in higher costs. Utility Model Content

[0005] This invention provides a tire inflation system and vehicle to solve the problem that the air tank and inflation components in the air storage and deflation components of related technologies need to be designed and manufactured separately, resulting in high costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] On one hand, a tire inflation system is provided, comprising an air tank, an air spring, a first connecting pipe, a tire, and a second connecting pipe. The air tank has a first air outlet and a second air outlet, the air spring has a first air inlet, and the first connecting pipe is connected to the first air outlet and the first air inlet. The tire has a second air inlet, and the second connecting pipe is connected to the second air outlet and the second air inlet, and the second connecting pipe is detachably connected to the second air inlet.

[0008] As described above, the first air outlet of the air tank is connected to the first air inlet of the air spring via the first connecting pipe, enabling the air tank to provide air for the air spring to adjust the vehicle's height. Simultaneously, the second air outlet of the air tank is connected to the second air inlet of the tire via the second connecting pipe, enabling the air tank to inflate the tire, thus ensuring the vehicle can continue to drive safely. In this configuration, the air tank can provide air for both the air spring and the tire, increasing its functionality and reducing the number of air tanks required in vehicle design and production, thereby lowering costs. Furthermore, the second connecting pipe is detachably connected to the second air inlet of the tire, allowing the second connecting pipe to be connected to the second air inlet of the next tire after inflating one tire, thus enabling inflating multiple tires, reducing the total length of the second connecting pipe and lowering production costs.

[0009] In some embodiments, the second connecting pipe includes a first pipe segment and a second pipe segment, which are detachably connected; the first pipe segment is connected to a second air outlet, and the second pipe segment is connected to a second air inlet. The first pipe segment may be located inside the vehicle, and the second pipe segment may be located outside the vehicle. The detachable connection eliminates the need for a connecting pipe outside the vehicle and facilitates the storage of the second pipe segment.

[0010] In some embodiments, the tire inflation system further includes a dual-connector, which includes a first interface and a second interface, wherein the first interface is detachably connected to a first pipe segment; and / or, the second interface is detachably connected to a second pipe segment. It is understood that with repeated tire inflation, the first or second interface of the dual-connector will wear down. Therefore, since the dual-connector is detachably connected to the first and second pipe segments, only the dual-connector needs to be replaced after wear occurs; there is no need to replace the connecting pipe, resulting in lower costs.

[0011] In some embodiments, the tire inflation system further includes a first valve disposed on a first pipe section. It is understood that the first valve controls the flow of air through the first pipe section where the first valve is located, thereby controlling the flow of air between the air tank and the dual-connector, effectively functioning as a switch. Simultaneously, when the first and second pipe sections are disconnected, the first valve ensures the normal operation of other vehicle systems.

[0012] In some embodiments, the tire inflation system further includes a second valve, which is disposed on the second pipe section. When multiple tires need to be inflated, the operator connects the second pipe section to the first pipe section via a double-connector and opens the first valve. Then, the valve on the second pipe section is connected to the second air inlet of the first tire, and the second valve is opened again to inflate the first tire. When the first tire is inflated and the second tire is being inflated, the second valve is closed and the valve is disconnected from the second air inlet of the first tire. The valve is then connected to the second air inlet of the second tire, and the second valve is opened again to inflate the second tire. The process of inflating multiple tires is repeated sequentially, and will not be described in detail here. When all tires are inflated, the second valve is closed and the valve and second air inlet are disconnected. Then, the first valve is closed and the first and second pipe sections are disconnected. During this process, the operator can directly replace the second air inlet connected to the valve by closing the second valve, without having to go to the trunk to close the first valve and then replace the second air inlet connected to the valve, thus improving the efficiency of inflating multiple tires. At the same time, directly closing the second valve, compared to closing the first valve in the trunk, can reduce the delay time in shutting off the air supply.

[0013] In some embodiments, the tire inflation system further includes a pressure relief valve disposed on the first pipe section, which is used to reduce the gas pressure output from the air tank to a preset value, so that the gas pressure input to the tire meets the normal tire pressure range.

[0014] In some embodiments, the preset value is 2.2 bar to 2.5 bar. It should be noted that the normal tire pressure range is 2.2 bar to 2.5 bar. Therefore, the preset value meets the normal tire pressure requirements.

[0015] In some embodiments, the air tank is provided with a third air inlet, and the tire inflation system further includes an inflation device and a third connecting pipe. The inflation device is provided with a third air outlet, and the third connecting pipe is connected to the third air outlet and the third air inlet. In this case, the inflation device and the air tank are connected through the third connecting pipe to achieve the function of inflation of the air tank.

[0016] On the other hand, a vehicle is provided that includes the tire inflation system described in the first aspect.

[0017] In some embodiments, the vehicle further includes a trunk, and the tire inflation system further includes a first valve and a two-way connector. The first valve has an operating part, and the two-way connector includes a first interface and a second interface. The operating part is located inside the trunk; and / or, the second interface is located inside the trunk. In this case, since the operating part is exposed inside the trunk, it is convenient for the operator to operate when it is necessary to open or close the first valve. At the same time, the operating part being located inside the trunk achieves the effect of not changing the original appearance and structure of the vehicle.

[0018] Therefore, the above-mentioned technical features of this utility model have the following beneficial effects:

[0019] (1) The first air outlet of the air tank is connected to the first air inlet of the air spring through the first connecting pipe, enabling the air tank to provide an air source for the air spring to adjust the vehicle's height. Simultaneously, the second air outlet of the air tank is connected to the second air inlet of the tire through the second connecting pipe, enabling the air tank to inflate the tire, thus ensuring the vehicle can continue to drive safely. In this configuration, the air tank can provide an air source for both the air spring and the tire, increasing its functionality and reducing the number of air tanks required in vehicle design and production, thereby lowering costs. Furthermore, the second connecting pipe is detachably connected to the second air inlet of the tire, allowing the second connecting pipe to be connected to the second air inlet of the next tire after inflating one tire, thus enabling inflating multiple tires, reducing the total length of the second connecting pipe and lowering production costs.

[0020] (2) The first pipe section can be installed inside the vehicle, and the second pipe section can be installed outside the vehicle. The first pipe section and the second pipe section are detachably connected, so that there is no need to leave a connecting pipe outside the vehicle, and it is convenient to store the second pipe section.

[0021] (3) As the number of times the tire is inflated increases, the first or second interface of the double connector will wear out. Therefore, since the double connector is detachably connected to the first and second pipe sections, only the double connector needs to be replaced after wear occurs, without replacing the connecting pipe connected to it, which is low cost.

[0022] (4) The first valve is used to control the flow of air in the first pipe section where the first valve is located, and thus to control the flow of air between the gas tank and the double-connector, thus realizing the function of a switch. At the same time, when the first pipe section and the second pipe section are disconnected, the first valve can ensure that other systems of the vehicle work normally.

[0023] (5) When multiple tires need to be inflated, the operator connects the second pipe section to the first pipe section via a double-connector and opens the first valve. Then, the valve on the second pipe section is connected to the second air inlet of the first tire, and the second valve is opened to inflate the first tire. When the first tire is inflated and the second tire is being inflated, the second valve is closed and the valve is disconnected from the second air inlet of the first tire. The valve is then connected to the second air inlet of the second tire, and the second valve is opened to inflate the second tire. The process of inflating multiple tires is repeated sequentially and will not be described in detail here. When all tires are inflated, the second valve is closed and the valve and second air inlet are disconnected. Then, the first valve is closed and the first and second pipe sections are disconnected. During this process, the operator can directly replace the second air inlet connected to the valve by closing the second valve, without having to go to the trunk to close the first valve and then replace the second air inlet connected to the valve, thus improving the efficiency of inflating multiple tires. At the same time, directly closing the second valve, compared to closing the first valve in the trunk, can reduce the delay time in shutting off the air supply.

[0024] (6) A pressure relief valve is installed on the first pipe section to reduce the gas pressure output from the gas tank to a preset value so that the gas pressure input to the tire meets the normal tire pressure range.

[0025] (7) The preset value is 2.2 bar to 2.5 bar. It should be noted that the normal tire pressure range is 2.2 bar to 2.5 bar. Therefore, the preset value meets the normal tire pressure requirements.

[0026] (8) The gas replenishment device and the gas storage tank are connected by a third connecting pipe to replenish the gas storage tank.

[0027] (9) Since the operating part is exposed inside the trunk, it is convenient for the operator to operate when it is necessary to open or close the first valve. At the same time, the operating part is located inside the trunk, so as not to change the original appearance structure of the vehicle.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0037] Figure 1 This application provides structural schematic diagrams of vehicles for some embodiments; Figure 2 Structural block diagrams of an air tank, tire, and second connecting pipe provided for some embodiments of this application; Figure 3 This is a schematic diagram of the structure of the air tank, air spring and first connecting pipe provided in some embodiments of this application.

[0038] like Figure 1As shown, this application embodiment provides a vehicle 1000, which can be any power-driven vehicle such as a fuel vehicle or a new energy vehicle. The vehicle 1000 includes a tire inflation system 100.

[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the tire inflation system 100 includes an air tank 10, an air spring 50, a first connecting pipe 40, a tire 30, and a second connecting pipe 20. The air tank 10 has a first air outlet 11 and a second air outlet 12. The air spring 50 has a first air inlet 51. The first connecting pipe 40 is connected to the first air outlet 11 and the first air inlet 51. The tire 30 has a second air inlet 31. The second connecting pipe 20 is connected to the second air outlet 12 and the second air inlet 31, and the second connecting pipe 20 and the second air inlet 31 are detachably connected.

[0040] As described above, the first air outlet 11 of the air tank 10 is connected to the first air inlet 51 of the air spring 50 via the first connecting pipe 40, enabling the air tank 10 to provide an air source for the air spring 50 to adjust the vehicle height of the vehicle 1000. Simultaneously, the second air outlet 12 of the air tank 10 is connected to the second air inlet 31 of the tire 30 via the second connecting pipe 20, enabling the air tank 10 to inflate the tire 30, thus ensuring the vehicle 1000 can continue to drive safely. In this configuration, the air tank 10 can provide an air source for both the air spring 50 and the tire 30, increasing the functionality of the air tank 10 and reducing the number of air tanks 10 in the design and production of the vehicle 1000, thereby reducing costs. In addition, the second connecting pipe 20 is detachably connected to the second air inlet 31 of the tire 30, which allows the second connecting pipe 20 to be connected to the second air inlet 31 of the next tire 30 after one tire 30 has been inflated, thereby enabling the inflation of multiple tires 30, reducing the total length of the second connecting pipe 20 and lowering production costs.

[0041] In some examples, such as Figure 3As shown, the vehicle 1000 also includes a height sensor 61, a height control unit 62, and a solenoid valve 63. The height sensor 61 and height control unit 62 are mounted on the frame of the vehicle 1000, and the solenoid valve 63 is mounted on the first connecting pipe 40. The height sensor 61 and height control unit 62 are connected via a first signal line 64, and the height control unit 62 and solenoid valve 63 are connected via a second signal line 65. The air tank 10 has a first air outlet 11, and the air spring 50 has a first air inlet 51. The first connecting pipe 40 is connected to the first air outlet 11 and the first air inlet 51. The height sensor 61 detects changes in the height of the vehicle 1000 and transmits the information to the height control unit 62. The height control unit 62 controls the operation of the solenoid valve 63, which controls the timing, duration, and cycle of inflation and deflation of the air spring 50 by the air tank 10, thereby adjusting the height of the vehicle 1000, suppressing the roll and pitch of the vehicle 1000, and improving ride comfort.

[0042] In some embodiments, such as Figure 3 As shown, the air tank 10 is provided with a third air inlet 13, and the tire inflation system 100 also includes an inflation device 70 and a third connecting pipe 80. The inflation device 70 is provided with a third air outlet 71, and the third connecting pipe 80 is connected to the third air outlet 71 and the third air inlet 13. In this case, the inflation device 70 and the air tank 10 are connected through the third connecting pipe 80 to achieve the function of inflation of the air tank 10.

[0043] In some examples, the air replenishment device 70 includes an air pump that draws in air and delivers it to the air storage tank 10 via a third connecting pipe 80, thereby replenishing the air storage tank 10.

[0044] In some embodiments, such as Figure 2 As shown, the second connecting pipe 20 includes a first pipe section 21 and a second pipe section 22. The first pipe section 21 and the second pipe section 22 are detachably connected. The first pipe section 21 is connected to the second air outlet 12, and the second pipe section 22 is connected to the second air inlet 31. The first pipe section 21 can be located inside the vehicle 1000, and the second pipe section 22 can be located outside the vehicle 1000. The detachable connection of the first pipe section 21 and the second pipe section 22 eliminates the need for a connecting pipe outside the vehicle 1000 and facilitates the storage of the second pipe section 22.

[0045] For example, the second pipe section 22 can be a flexible hose, which is easy to operate and bend, making it convenient for operators to connect the second pipe section 22 to the second air inlet 31 and to place the second pipe section 22.

[0046] In some examples, such as Figure 2As shown, the tire inflation system 100 includes a valve 27, which is airtightly connected to the second air inlet 31 and is detachable, enabling it to inflate multiple tires 30 and prevent air leakage during the inflation process.

[0047] In some embodiments, such as Figure 2 As shown, the tire inflation system 100 also includes a dual-connector 23, which includes a first interface 231 and a second interface 232. The first interface 231 is detachably connected to the first pipe segment 21; and / or, the second interface 232 is detachably connected to the second pipe segment 22. It is understood that as the number of times the tire 30 is inflated increases, the first interface 231 or the second interface 232 of the dual-connector 23 will wear down. Therefore, since the dual-connector 23 is detachably connected to the first pipe segment 21 and the second pipe segment 22, after wear occurs, only the dual-connector 23 needs to be replaced; there is no need to replace the connecting pipe, resulting in lower costs.

[0048] In some embodiments, such as Figure 2 As shown, the tire inflation system 100 also includes a first valve 24, which is disposed on the first pipe section 21. It can be understood that the first valve 24 is used to control the flow of air through the first pipe section 21, where the first valve 24 is located, and thus to control the flow of air between the air tank 10 and the double-connector 23, achieving a switch function. Simultaneously, when the first pipe section 21 and the second pipe section 22 are disconnected, the first valve 24 ensures the normal operation of other systems in the vehicle 1000.

[0049] Figure 4 Structural block diagram of the trunk provided for some embodiments of this application.

[0050] In some embodiments, combined with Figure 1 , Figure 2 and Figure 4 The vehicle 1000 also includes a trunk 90, and the tire inflation system 100 includes a first valve 24 and a dual-connector 23. The first valve 24 has an operating part 241, and the dual-connector 23 includes a first interface 231 and a second interface 232. The operating part 241 is located inside the trunk 90; and / or, the second interface 232 is located inside the trunk 90. ​​In this case, since the operating part 241 is exposed inside the trunk 90, it is convenient for the operator to operate when it is necessary to open or close the first valve 24. At the same time, the operating part 241 is located inside the trunk 90, which achieves the effect of not changing the original appearance structure of the vehicle 1000.

[0051] In some examples, the trunk 90 includes a spare tire compartment 91, which is located at the bottom of the trunk 90, and the first operating part 241 and the second interface 232 are located inside the spare tire compartment 91. It is understood that the spare tire compartment 91, being located at the bottom of the trunk 90 and closer to the air tank 10, can shorten the length of the first pipe segment 21 connecting to the air tank 10 and the first interface 231.

[0052] In some embodiments, such as Figure 2 As shown, the tire inflation system 100 also includes a second valve 25, which is located on the second pipe section 22. The second valve 25 controls the flow of air through the second pipe section 22. When multiple tires 30 need to be inflated, the operator connects the second pipe section 22 to the first pipe section 21 via a double-connector 23 and opens the first valve 24. Then, the air nozzle 27 on the second pipe section 22 is connected to the second air inlet 31 of the first tire 30, and the second valve 25 is opened to inflate the first tire 30. When the first tire 30 is inflated and the second tire 30 is to be inflated, the second valve 25 is closed and the air nozzle 27 is disconnected from the second air inlet 31 of the first tire 30. Then, the air nozzle 27 is connected to the second air inlet 31 of the second tire 30, and the second valve 25 is opened to inflate the second tire 30. The process of inflating multiple tires 30 is repeated sequentially, and will not be described in detail here. After all tires 30 have been inflated, close the second valve 25 and disconnect the valve stem 27 and the second air inlet 31. Then close the first valve 24 and disconnect the first pipe section 21 and the second pipe section 22. During this process, the operator can directly replace the second air inlet 31 connected to the valve stem 27 by closing the second valve 25, eliminating the need to go to the trunk 90 to close the first valve 24 and then replace the second air inlet 31 connected to the valve stem 27, thus improving the efficiency of inflating multiple tires 30. Furthermore, directly closing the second valve 25, compared to going to the trunk 90 to close the first valve 24, reduces the time spent closing the inflator.

[0053] In some examples, the second valve 25 is located on the end of the second pipe section 22 near the air nozzle 27. This arrangement allows the second valve 25 to be located close to the tire 30, making it easier for the operator to open and close the second valve 25.

[0054] In some examples, combined Figure 2 and Figure 4The trunk 90 also includes a storage box 92, which is located at the bottom of the trunk 90 and on one side of the spare tire box 91. The second pipe section 22, the second valve 25 and the air nozzle 27 can be placed in the storage box 92, which facilitates the access to the second pipe section 22, the second valve 25 and the air nozzle 27, and protects the second pipe section 22, the second valve 25 and the air nozzle 27 from rolling or flying out and causing damage during the driving of the vehicle 1000.

[0055] In some embodiments, such as Figure 2 As shown, the tire inflation system 100 also includes a pressure relief valve 26, which is installed on the first pipe section 21 and is used to reduce the gas pressure output from the air tank 10 to a preset value so that the gas pressure input to the tire 30 meets the normal pressure range of the tire 30.

[0056] In some embodiments, the preset value is 2.2 bar to 2.5 bar. It should be noted that the normal tire pressure range for tire 30 is 2.2 bar to 2.5 bar; therefore, the preset value meets the normal tire pressure requirements for tire 30. For example, the preset value can be 2.2 bar, 2.4 bar, or 2.5 bar.

[0057] In some embodiments, the air pressure range of the air tank 10 is 6 bar to 20 bar. It should be noted that the air pressure range required for the normal operation of the air spring 50 is 6 bar to 20 bar, which is greater than the normal air pressure range of the tire 30. Therefore, the air pressure range of the air tank 10 should simultaneously meet the normal operating requirements of both the air spring 50 and the tire 30. For example, the air pressure of the air tank 10 can be 6 bar, 14 bar, or 20 bar.

[0058] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
