Description

Technical Field

[0001] This utility model relates to the field of tire inflation, specifically a control system for automatic inflation of aircraft tires. Background Technology

[0002] Aircraft tires are crucial components that ensure the aircraft's movement on the ground. To maintain proper tire function, they need to be inflated periodically. Typically, tire inflation is done manually by opening and closing valves. This requires operators to frequently open and close the valves, monitoring the inflation pressure. All operations are manual, demanding high levels of responsiveness from the personnel. Furthermore, it's difficult to manually control the valve opening, often resulting in inflation exceeding the actual pressure, necessitating deflation. The entire inflation process is cumbersome. Utility Model Content

[0003] To achieve the above objectives, the purpose of this utility model is to provide a control system for automatic inflation of aircraft tires, which can solve the problems existing in the background art. This utility model provides the following technical solution:

[0004] A control system for automatic aircraft tire inflation includes a first connector, a second connector, a panel, a pressure reducer, and a burst-proof cage for holding the tire. Both the first and second connectors are connected to a pipeline connector, which is equipped with a vent valve and connected to an inflation hose. The panel is electrically connected to a pressure sensor, the vent valve, and a solenoid valve. The panel is mounted on an electrical control box, which also houses indicator lights, a pressure sensor, and the solenoid valve. The pressure reducer is connected to a nitrogen cylinder via the pipeline connector and a connecting pipe. The burst-proof cage is used to push the tire into the cage during inflation to prevent accidental tire bursting. The inflation port is located on the tire and is used for inflating it. The first and second connectors connect to the pipeline connector; the appropriate connector is used depending on the tire model. During inflation, the first and second connectors are aligned with the inflation port. Both sides of the inflation hose are connected to the pipeline connector. The vent valve is connected to the pipeline via the pipeline connector; when the tire pressure is too high, air can be released through it. The solenoid valve is connected to the pipeline via a pipe connector and controlled via a panel to control the on / off state of the gas path. The pressure sensor is also connected to the pipeline via a pipe connector; it primarily collects the pipeline pressure and inputs an analog signal to the panel. Indicator lights are fixed to the electrical control box and are mainly used to provide feedback on the equipment's operation, such as standby, running, and fault status, allowing operators to quickly assess the equipment's condition. The panel, also fixed to the electrical control box, is primarily used to control the equipment's inflation process and for human-machine interaction. The solenoid valve, pressure sensor, indicator lights, and panel are all mounted on the electrical control box, which houses all the electrical components of the equipment. Pipe connectors and connecting pipes are interconnected, forming the gas path for the entire inflation pipeline. The pressure reducer is connected to the nitrogen cylinder via pipe connectors and connecting pipes, primarily reducing the high-pressure nitrogen in the cylinder to the low-pressure nitrogen required by the equipment. The nitrogen cylinder provides the gas source for the entire equipment. The operating process of this product is as follows: The operator rolls the tire into the explosion-proof cage, then selects the corresponding first or second connector according to the tire model, and connects the corresponding connector to the inflation port. The deflation valve is closed. The pressure reducer is connected to the nitrogen cylinder through the pipe connector and pipe connection pipe. The nitrogen cylinder is opened, and the pressure reducer reduces the high-pressure nitrogen in the cylinder to the low-pressure nitrogen required for equipment inflation. Then, power is supplied to the electrical control box. After power is supplied, the panel begins to display, and the indicator lights reflect the equipment's operating status. During use, the operator only needs to set the upper and lower inflation limits on the panel, and then press the start button on the panel. The panel controls the solenoid valve to open and close intermittently, thus inflating the tire. During the period when the solenoid valve is closed, the pressure sensor detects the current tire pressure. When the pressure approaches the required value, the panel controls the solenoid valve to open and close more frequently until the pressure sensor detects that the tire pressure value matches the required value, at which point inflation stops.Furthermore, during the entire inflation process, indicator lights will provide signal guidance to the operator.

[0005] As a further embodiment of this utility model: both the first connector and the second connector are quick-connect connectors, which are simple to operate and have a fast connection speed.

[0006] As a further embodiment of this utility model, both the inflation tube and the connecting tube are made of flexible tubing.

[0007] As a further embodiment of this invention, both the venting valve and the solenoid valve are ball valves.

[0008] As a further solution of this utility model: the panel adopts a touch screen all-in-one machine, which is simple to operate and has good stability.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This product is simple to operate and requires minimal manual intervention; operators only need to observe the inflation process, making it convenient and quick. Furthermore, this product is suitable for various tire models, and by expanding the inflation circuit, it can inflate multiple tires simultaneously. Attached Figure Description

[0015] See Figure 1A control system for automatic inflation of aircraft tires includes a first connector 4, a second connector 5, a panel 11, a pressure reducer 14, and a blast-proof cage 1 for holding the tire. Both the first connector 4 and the second connector 5 are connected to a pipe connector 13. A vent valve 7 is installed on the pipe connector 13, and the pipe connector 13 is connected to an inflation pipe 6. The panel 11 is electrically connected to a pressure sensor 9, the vent valve 7, and a solenoid valve 8. The panel 11 is mounted on an electrical control box 12, which also houses an indicator light 10, the pressure sensor 9, and the solenoid valve 8. The pressure reducer 14 is connected to a nitrogen cylinder 16 via the pipe connector 13 and a pipe connecting pipe 15. The blast-proof cage 1 is used to push the tire 2 into it during inflation to prevent accidental bursting of the tire 2. The inflation port 3 is located on the tire 2 and is used for inflating the tire 2. The first connector 4 and the second connector 5 are connected to the pipe connector 13. The corresponding connectors are changed according to the different tire models 2. During inflation, the first connector 4 and the second connector 5 are connected to the inflation port 3. Both sides of the inflation pipe 6 are connected to the pipe connector 13. The deflation valve 7 is connected to the pipe through the pipe connector 13. When the tire pressure 2 is too high, it can be deflated through this valve. The solenoid valve 8 is connected to the pipe through the pipe connector 13 and is controlled by the panel 11 to control the air passage. The pressure sensor 9 is connected to the pipe through the pipe connector 13. It mainly collects the pressure in the pipe and then inputs an analog signal to the panel 11. The indicator light 10 is fixed on the electrical control box 12 and is mainly used to provide signal feedback on the operation of the equipment, such as standby, running, and fault status feedback, allowing operators to quickly judge the equipment status. The panel 11 is fixed on the electrical control box 12 and is mainly used for controlling the inflation of the equipment and for human-machine interaction. Solenoid valve 8, pressure sensor 9, indicator light 10, and panel 11 are all mounted on electrical control box 12, which is the location for all electrical components of the equipment. Pipe connector 13 and pipe connecting pipe 15 are interconnected, forming the gas path for the entire inflation pipeline. Pressure reducer 14 is connected to nitrogen cylinder 16 via pipe connector 13 and pipe connecting pipe 15, primarily to reduce the high-pressure nitrogen in nitrogen cylinder 16 to the low-pressure nitrogen required by the equipment. Nitrogen cylinder 16 provides the gas source for the entire equipment. The operating process of this product is as follows: The operator rolls tire 2 into explosion-proof cage 1, then selects the corresponding first connector 4 or second connector 5 according to the tire 2 model, and connects the corresponding connector to inflation port 3. The vent valve 7 is closed. The pressure reducer 14 is connected to nitrogen cylinder 16 via pipe connector 13 and pipe connecting pipe 15. Nitrogen cylinder 16 is opened, and the pressure reducer 14 reduces the high-pressure nitrogen in nitrogen cylinder 16 to the low-pressure nitrogen required for equipment inflation. Then power is supplied to the electrical control box 12. After power is supplied, the panel 11 begins to display, and the indicator lights 10 reflect the operating status of the equipment.In use, the operator only needs to set the upper and lower inflation limits on the panel 11, and then press the start button on the panel 11. The panel 11 controls the solenoid valve 8 to open and close intermittently, thereby inflating the tire 2. During the period when the solenoid valve 8 is closed, the pressure sensor 9 detects the current tire pressure of the tire 2. When the air pressure approaches the required value, the panel 11 controls the solenoid valve 8 to open and close at a faster frequency until the pressure sensor 9 detects that the tire pressure value of the tire 2 matches the required value, at which point inflation stops. Throughout the inflation process, an indicator light 10 will provide signal guidance to the operator.
