Description

A vehicle-mounted tire inflation device

technical field

The utility model relates to a tire inflation device carried and driven by an automobile, which belongs to the technical field of automobiles.

Background technique

The popularity of automobiles has brought great convenience to people's travel. Most modern cars use tubeless tires. During the use of the tires, sometimes the phenomenon of jogging gas occurs due to tire punctures and other reasons, resulting in a gradual decrease in tire pressure. When the tire pressure drops to a certain level, the car cannot run normally. The usual solution to this type of problem is to replace the spare tire and then go to a nearby repair shop to get it repaired. However, replacing the spare tire requires proficient operation of auxiliary tools such as jacks and the need to move the tire, which requires certain skills and physical conditions of the driver. Therefore, it is difficult for some drivers to solve it by themselves, and changing the spare tire will stain the clothes and skin. Bring a lot of troubles to car drivers, especially white-collar workers and female drivers. If the car does not have a spare tire or the spare tire is damaged, you need to wait for rescue, which will waste more time for the driver and cause greater inconvenience to the life and work of the driver. Therefore, people are in urgent need of a kind of on-board inflation device that can inflate tires at any time, to thoroughly eliminate the worry that tire jogging gas brings to the crew.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a vehicle-mounted tire inflation device carried and driven by the vehicle.

The purpose of this utility model is realized with following technical scheme:

A vehicle-mounted tire inflation device, which includes a three-way and a pressure regulator, the air inlet of the three-way is connected with the quick socket of the intercooler of the turbocharger system of the automobile engine through a quick plug, and one air outlet of the three-way Inflate the tire, and connect the other air outlet to the pressure regulator.

The vehicle-mounted tire inflation device also includes a diaphragm alarm in the composition, and the diaphragm alarm is connected to the exhaust port of the pressure regulator.

In the above vehicle-mounted tire inflation device, the air inlet of the three-way is provided with a one-way valve.

The utility model uses the turbocharger system of the automobile engine as the power source to inflate the tires, and has the advantages of simple structure, low cost and high reliability. The installation is very convenient and fast, which solves the problem of temporary inflation of vehicle tires well, completely eliminates the troubles caused by tire jogging gas to passengers and drivers, and has high promotion value.

Description of drawings

Fig. 1 is a structural representation of the utility model.

The labels in the figure are: 1. Turbocharger; 2. Intercooler; 3. Intercooler shortcut socket; 4. Quick plug; 5. Tee; 6. Voltage regulator; 7. Diaphragm alarm; 8. Tires.

Detailed ways

Referring to Fig. 1, the utility model is made up of tee 5, pressure regulator 6, diaphragm alarm 7 and connecting pipeline. The turbocharger is the power source of the engine. According to different pressures, it is divided into low boost P _b ≤ 0.17MPa, medium boost 0.17MPa < P _b ≤ 0.25MP, high boost 0.25MPa < P _b ≤ 0.35MPa , Ultra-high pressure P _b > 0.35MPa, the car is generally medium pressure, the tire pressure is generally 0.20 MPa, judging from the pressure value that the pressure is higher than the rated pressure of the tire, it can provide inflation for the tire. When the engine starts and reaches a certain speed (generally about 1500 rpm), the turbocharger 1 starts to compress the air. After the compressed air is cooled by the intercooler 2, it reaches the inside of the tire 8 through the tee 5 and the connecting pipeline. When the tire pressure When the rated pressure is reached, the excess gas is discharged through the pressure regulator 6. The diaphragm alarm 7 installed at the outlet of the pressure regulator 6 is a diaphragm siren. When the high-pressure gas flows through the diaphragm alarm 7, the diaphragm of the siren vibrates and sends out an alarm sound, prompting the owner to complete inflation;

A one-way valve is integrated in the three-way 5. When the air source is disconnected, the one-way valve is closed to ensure that the gas in the tire will not leak out. The connecting pipeline is connected to the tire with an ordinary pumping joint; the three-way 5 uses a quick plug 4 to connect with the engine. The intercooler 2 is connected, and the quick socket 3 of the intercooler is an iron pipe matched with the quick plug 4. When it is not inflated, it is blocked with a quick plug cap.

When the tires of the vehicle need to be inflated, connect this device with the intercooler 2 and the tires 8, start the engine after the installation is complete, and lift the gas pedal in the idling state to increase the pressure of the supercharger. When the alarm is heard, the inflation is completed. , shut off the engine, remove the inflator, and return the engine booster cap.

The parts used in the device are common parts, easy to obtain, and low in cost.
