Tire pressure detector with centre-of-gravity shift

Abstract

The invention provides a tire pressure detector with centre-of-gravity shift. The tire pressure detector with the centre-of-gravity shift is used for a wheel. The wheel is provided with a rim sectionand a tire. Air pressure space is formed between the tire and the rim section. An air nozzle which communicates with the air pressure space is arranged on the rim section. The tire pressure detector includes a tire pressure detector body and a detection module. The tire pressure detector body is movably arranged in the air pressure space and is provided with accommodating space. The tire pressuredetector body is provided with long axles with different lengths and short axles perpendicular to the long axles. The detection module is located in the accommodating space, and the detection module is used for sensing the air pressure in the air pressure space. Therefore, the tire pressure detector body can rotate in the direction of the long axles, and can be installed without any tools, and theeffect of convenient installation is achieved.

Description

technical field [0001] The invention relates to a related field of tire pressure detection for wheels, in particular to a tire pressure detector with center of gravity offset. Background technique [0002] The tire pressure detector is an electronic system installed on the wheel to detect whether the air pressure of the tire is sufficient. This system will detect in real time and let the driver know by instrument, digital display or simply by light or sound. Know the changes in tire pressure to reduce traffic accidents caused by over-inflated or under-inflated tires. [0003] The operation mode of the tire pressure detector can be mainly divided into indirect type and direct type. Among them, the indirect tire pressure detector does not directly detect the tire pressure, but detects the rotation speed of the wheel. If the system detects that the rotation speed of a certain wheel is too different from the rotation speed of other wheels, there may be a If the tire pressure i...

Problems solved by technology

Among them, the indirect tire pressure detector does not directly detect the tire pressure, but detects the rotation speed of the wheel. If the system detects that the rotation speed of a certain wheel is too different from the rotation speed of other wheels, there may be a If the tire pressure is abnormal, the driver will be reminded. However, the indirect tire pressure detection system cannot provide the driver with the actual tire pressure value.

[0004] Furthermore, the direct type tire pressure detection system, its sensor with signal transmission function, can provide the actual tire pressure value of the driver's wheel. Among them, according to the installation method, it can be divided into two types: the tire outside type and the inside type. The sensor is installed on the air nozzle of the wheel, which can be easily installed by the car owner. However, due to the weight of the sensor itself, locking it on the air nozzle will cause uneven distribution of the wheel mass, which will affect the wheel balance. Risk of damaging the sensor

[0005] Moreover, when the rubber valve is combined with the tire outside sensor, there will be a phenomenon of swinging when the vehicle is moving, and the rubber body of the rubber valve may be at risk of breaking after long-term operation.

In addition, the in-tire sensor is installed in the rim of the wheel, and the tire needs to be disassembled for installation. Since it is generally a fixed tire pressure detector, the air nozzle needs to be locked on the rim. During installation, it is often Due to the careless construction of the technician, the tire skin or tools for dismantling the tire directly hit the valve or the sensor, causing the valve to break or the sensor to be damaged, resulting in additional costs for the merchant
