Description

Technical Field

[0001] The utility model relates to the technical field of tire pressure monitoring systems, in particular to an inner tube of an engineering load vehicle with a tire pressure monitoring system. Background Art

[0002] Automobile tire pressure monitoring system, airbag system and seat belt system are equipped in automobiles. They are called the three major safety systems and can ensure the driving safety of drivers. Abroad. Around 2012, countries such as Europe, the United States, Japan and South Korea have written automobile tire pressure monitoring system into the law.

[0003] In 2017, the TPMS penetration rate in the Chinese market was about 30%, mainly installed on mid-to-high-end models.

[0004] On October 14, 2017, the Standardization Administration of China officially approved the mandatory national standard "Performance Requirements and Test Methods for Passenger Car Tire Pressure Monitoring Systems" (GB26149-2017), requiring that from January 1, 2019, all newly certified passenger cars in the Chinese market must be equipped with TPMS; from January 1, 2020, all passenger cars produced will begin to implement mandatory installation requirements.

[0005] For vehicles other than passenger cars (including engineering vehicles, trucks, etc.), there are currently no relevant regulations in the corresponding laws and regulations because the tire pressure monitoring system technology is still immature (especially for vehicles with inner tube tires).

[0006] 2. Existing tire pressure monitoring system:

[0007] 1) Principle of tire pressure monitoring system

[0008] When the car is stationary or moving, the tire pressure monitoring system automatically collects and wirelessly forwards information such as tire pressure and tire pressure sensor power in real time. In addition, the tire pressure monitoring system promptly transmits important alarm information such as high-pressure and low-pressure tire leakage and low sensor power to the driver of the moving car, so that he can quickly understand the tire information of his vehicle and ultimately avoid tire blowouts during driving, ensuring the driving safety of the car driver.

[0009] 2) Composition of tire pressure monitoring system

[0010] The tire pressure monitoring system is composed of a combination instrument display interface, a tire pressure monitoring system controller, and a sensor. The tire pressure sensor is attached to the inner wall of the inner tube, and then transmitted to the display screen in the cab through a signal collector. It displays the tire pressure and tire pressure monitoring.

[0011] The specific working process of the tire pressure monitoring system is:

[0012] First, the tire pressure sensor collects and monitors the tire pressure;

[0013] Then, it is transmitted to the TPMS controller box wirelessly; the TPMS controller box performs logic judgment decoding;

[0014] Finally, it sends the judgment result to the display interface of the instrument cluster through the CAN line. The instrument cluster uses warning lights and buzzers to warn the driver of abnormal tire failure.

[0015] 3. The tire pressure monitoring system for vehicles with inner tube tires is currently in a technical blank area, and there is no mature technology for tire pressure monitoring. The current technical difficulties include:

[0016] 1. The air pressure of a tube-type tire is concentrated inside the inner tube. After the inner tube is installed, it is difficult to collect tire pressure data unless it is inserted destructively.

[0017] 2. Before the inner tube is formed, the tire pressure monitoring system is installed. Due to the high-temperature steam vulcanization characteristics of the inner tube, attention should be paid to the heat and steam resistance of the monitoring module.

[0018] 3. The necessity of installing tire pressure monitoring systems on non-passenger vehicles and the degree of cooperation from vehicle manufacturers and users.

[0019] 4. Due to the large number of tires, construction vehicles and cargo vehicles have new requirements on cost economy and complexity of control system software.

[0020] Therefore, how to provide an inner tube of an engineering truck with a tire pressure monitoring system to solve the problems existing in the prior art is of great significance for its application. Utility Model Content

[0045] The sensor 1 is installed on the inner wall of the inner tube body 2, and the air nozzle 3 is installed on the outer wall of the inner ring of the inner tube body. The installation position of the sensor 1 is not limited to the inner wall of the inner tube body. Figure 1 The sensor 1 can be installed at the location of the inner wall, inner circle or outer circle. When installing the air nozzle 3, first open a hole in the inner wall of the unconnected tire tube, then pass the air nozzle 3 through the hole, and fix it with adhesive.

[0046] The sensor 1 includes an outer protective layer 11, a sensing unit 12, a wall-attached bottom sheet 13, a signal transmission unit 14, a circuit board 15 and a battery 16;
