Description

Technical Field

[0001] This invention relates to the field of automotive repair and emergency equipment technology, specifically to a vehicle-mounted emergency inflation device based on tire air storage and its inflation method. Background Technology

[0002] As an important means of daily transportation, proper tire pressure is crucial for ensuring driving safety in automobiles. In actual use, sometimes individual tires may lose pressure, rendering the vehicle unable to move; in more serious cases, the tire bead may slip off the rim bead seat.

[0003] To address the above situation, existing solutions mainly rely on onboard air compressors for inflation or tire replacement with a spare tire, or external equipment for pressure boosting. However, these solutions have the following shortcomings in practical applications: Firstly, replacing a spare tire is cumbersome, and some users lack the ability to do so independently. Secondly, when the tire bead detaches from the rim bead seat, the air pressure and flow rate output by a conventional onboard air compressor are insufficient to achieve proper tire positioning (even if the tire bead repositions and adheres to the rim bead seat), resulting in incomplete inflation. Furthermore, external pressure boosting equipment is often difficult to obtain in remote areas or emergency situations, making it impossible to resolve the problem promptly.

[0004] In existing technologies, the potential of tires as natural air storage containers has not been fully utilized. Although the concept of tire pressure balance exists, there is a lack of specialized and reliably sealed connection devices, making it impossible to achieve stable gas delivery; furthermore, no technical solution has been proposed to use an on-board air pump to pressurize normal tires into a high-pressure air storage source to solve the problem of "tire sitting" when the tire bead detaches from the rim.

[0005] Therefore, there is an urgent need for a vehicle-mounted emergency inflation device and corresponding method that is simple in structure, easy to use, and adaptable to both general emergency inflation scenarios and tire bead reset scenarios, in order to make up for the shortcomings of existing technologies. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing vehicle-mounted emergency inflation technology in that it cannot effectively inflate in extreme scenarios (such as when the tire bead detaches from the rim), and to provide a compact and reliably sealed vehicle-mounted emergency inflation device; at the same time, it provides an inflation method based on the device, which uses the vehicle's own normal tires as an air storage source to achieve "tire-sitting" operation in extreme scenarios and tire pressure balance in normal scenarios, thus creating conditions for the vehicle to travel to a repair station.

[0007] To solve the above-mentioned technical problems, the present invention provides a vehicle-mounted emergency inflation device based on tire air storage, comprising:

[0008] An air supply pipe, one end of which is provided with an air receiving end connector for connecting to the tire to be inflated;

[0009] An air source connection assembly includes an air source valve and an air supply end connector; the outlet of the air source valve is connected to the other end of the air transmission pipe, and its inlet is connected to a tire as an air storage source through the air supply end connector.

[0010] Both the gas supply end connector and the gas receiving end connector are equipped with sealing elements at their connection points with the gas transmission pipe.

[0011] In some embodiments of the present invention, the air supply end connector includes a connecting pipe and a first valve connector, one end of the connecting pipe being connected to the inlet of the air source valve and the other end being connected to the first valve connector.

[0012] In some embodiments of the present invention, the gas receiving end connector is a second valve connector, which is directly connected to one end of the gas supply pipe.

[0013] In some embodiments of the present invention, the gas source valve is characterized as a ball valve.

[0014] In some embodiments of the present invention, according to the method of claim 6, the valve core of the high-pressure air-storage tire and / or the depressurized tire is first removed, and then the threaded valve is screwed into the corresponding tire valve thread.

[0015] A vehicle-mounted emergency inflation method based on tire air storage includes the following steps:

[0016] S1. High-pressure air source tire: Using an on-board air pump, the air pressure of at least one normal tire is increased to near its rated maximum pressure to form a high-pressure air storage tire;

[0017] S2. Connecting pipes: Connect the air supply end connector of the vehicle-mounted emergency inflation device to the high-pressure air storage tire, and connect the air receiving end connector to the deflated tire;

[0018] S3. Release airflow impact: Open the air source valve to release the high-pressure gas in the high-pressure storage tire to the deflated tire through the air supply pipe. The generated high-pressure airflow impacts the inner wall of the deflated tire to complete the tire bead reset.

[0019] In some embodiments of the present invention, when a threaded valve valve device is used, in step S2, the valve cores of the high-pressure storage tire and / or the depressurized tire must first be removed, and then the threaded valve valve is screwed into the corresponding tire valve thread.

[0020] In some embodiments of the present invention, after step S3, the method further includes:

[0021] S4. Replenish air pressure: Keep the vehicle-mounted emergency inflation device connected, or use a vehicle-mounted air pump to replenish air into the tires that have completed bead reset, until they reach a driving pressure.

[0022] A method for balancing pressure between tires includes:

[0023] Connect the air supply end connector of the device to the first tire with higher air pressure, and connect the air receiving end connector 2 to the second tire with lower air pressure.

[0024] Open the air supply valve to allow the air in the first tire to flow to the second tire until the air pressure of the two tires is balanced or the second tire reaches the target pressure.

[0025] The advantages of this invention compared to the prior art are:

[0026] This invention utilizes the pressure of a vehicle's normal tires as a high-pressure air source, combined with a dedicated emergency inflation device, to provide high-pressure, high-capacity compressed air. This enables a "sitting" operation when the tire bead detaches from the rim, solving the problem of tire bead repositioning that conventional vehicle-mounted air compressors cannot handle. It addresses both scenarios requiring "sitting" when the tire bead detaches from the rim and scenarios involving pressure balancing between tires. It eliminates the need for additional large air storage equipment. In scenarios involving pressure balancing between tires, emergency inflation can be achieved through the pressure difference between tires when a vehicle-mounted air pump is not available, enhancing the device's practicality and versatility. The device consists of core components such as an air supply pipe, air source valve, and connectors, featuring a compact structure for easy vehicle storage. Connection is simple, requiring no professional skills; users can quickly complete pipe connections and inflation operations. Each connection point is equipped with a seal, working with the connecting pipe and ball valve to ensure leak-free high-pressure gas delivery. The threaded valve simplifies connection, increases airflow channels, and improves inflation efficiency. Attached Figure Description

[0039] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0041] Example 1: Standard Connection Device

[0042] like Figures 1 to 3 As shown, the vehicle-mounted emergency air-filling device of this embodiment includes an air supply pipe 1 as the main passage. A standard second valve connector 21 is directly installed at the right end of the air supply pipe 1, serving as the air receiving end connector 2. An air source valve 3, which is a ball valve in this example, is connected to the left end of the air supply pipe 1. The inlet end of the air source valve 3 is connected to a standard first valve connector 42 via a connecting pipe 41 (a connecting pipe made of brass is used in this embodiment). The first valve connector 42, the connecting pipe 41, and the air source valve 3 together constitute the air supply end connection assembly. O-rings or Teflon tape seals 5 are press-fitted between the first valve connector 42 and the air supply pipe 1, and between the second valve connector 21 and the air supply pipe 1, to ensure airtightness under high pressure.

[0043] Example 2: Threaded quick-connect device

[0044] like Figure 4 and Figure 5As shown, this embodiment is an improvement upon embodiment one. The air receiving end connector 2 is replaced with a threaded valve stem 6. This threaded valve stem 6 has an internal thread 61. Before use, the valve core on the target tire valve stem needs to be removed to expose the tire valve stem thread and central through hole on the tire valve stem base. Then, the threaded valve stem 6 is directly screwed onto the thread, achieving a quick, straight-through connection. The air supply end connector can also be replaced with a threaded valve stem 6. The airflow speed is fastest when both ends use threaded valve stems 6.

[0045] Application Example 1: High-Pressure Gas Storage Tire Bead Reset Method (using the threaded quick-connect structure of Example 2)

[0046] When a vehicle's tires become underinflated to the point that the tire bead slips off:

[0047] (1) Air storage preparation: Use a vehicle-mounted electric air pump to pressurize a coaxial or adjacent normal tire to near its rated maximum safety pressure (e.g., if the rated pressure is 350 kPa, inflate it to 330 kPa) to form a "high-pressure air storage tire".

[0048] (2) Quick connection: Close the air supply valve 3. Use a valve core wrench to remove the valve cores of the "high-pressure storage tire" and the "depressurized tire". Tighten the threaded valve 6 (air receiving end and air supply end) of the device to the valve core base of the depressurized tire and the high-pressure tire.

[0049] (3) Instant impact: Quickly turn the air source valve 3 to full open. The gas in the "high pressure storage tire" rushes into the cavity of the depressurized tire. Using the impact force and flow of the gas expansion, positive pressure is instantly formed in the inner cavity of the tire, pushing the tire bead back into the rim groove.

[0050] (4) Restore tire pressure: After the tire bead is reset, close the air supply valve 3. Remove the device and reinstall the valve cores of both tires. Finally, use the vehicle's air pump to inflate the reset tires to the standard tire pressure.

[0051] Application Example 2: Rapid Tire Pressure Balancing Method (using the standard connection structure of Example 1)

[0052] When a tire is low on air and cannot be driven, requiring emergency inflation:

[0053] (1) Prepare for connection: Close the gas source valve 3.

[0054] (2) Connecting device: Connect the first valve stem connector 42 to the valve core of the tire at the supply end; connect the second valve stem connector 21 to the valve core of the tire that needs to be inflated.

[0055] (3) Quick inflation: Open the air supply valve 3. Air is pumped from the tire with normal pressure to the tire with low pressure until the tire pressure is balanced. After the required pressure is reached, close the valve and remove the device to quickly complete the pressure balance between the tires.

[0056] Application Example 3: Emergency air supply for pneumatic equipment or tools

[0057] In addition to its use for gas transfer between tires, the device of this invention can also be used as an independent emergency gas source to power small pneumatic equipment or tools. Specific application methods are as follows:

[0058] (1) Prepare for connection: Close the gas source valve 3.

[0059] (2) Equipment Connection: Connect the first valve connector 42 or the threaded valve 6 of the air supply end connector of the device to the valve of the aforementioned air-supplying tire. At the air receiving end, the second valve connector 21 or the threaded valve 6 can be converted into a quick-connect fitting, metric thread fitting, or other standard pneumatic interface to connect to the air inlet of pneumatic equipment that requires air supply, such as a pneumatic wrench, pneumatic jack, pneumatic spray gun, or an air inflator for inflating tires of other vehicles.

[0060] (3) Emergency use: Slowly open the air source valve 3. Compressed air from the air supply tire will be delivered to the pneumatic equipment via the air supply pipe 1 to drive it. The output airflow and pressure can be adjusted by controlling the opening of the air source valve 3 to meet the needs of different tools.

[0061] This invention is particularly useful in emergency situations such as remote areas lacking fixed air sources and roadside rescue sites. It makes full use of the vehicle's own resources, converting the tires into a mobile, unpowered, simple compressed air supply station, thus expanding the vehicle's emergency self-rescue and mutual rescue capabilities.

[0062] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
