Problems solved by technology

However, there are still some drivers who are unwilling to wear seat belts. Drivers can easily be fooled by inserting the deadbolt into the buckle with a fake deadbolt or inserting the deadbolt into the buckle with the webbing attached to the seat. Systematic detection hides a huge potential safety hazard

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with embodiment.

[0030] During specific implementation: if Figure 1~Figure 5As shown, a safety belt assembly capable of detecting the buckled state includes a retracting device, a safety belt 14, a lock tongue 7, a guide 8 and a buckle 9, and the retracting device and the guide 8 are installed on a seat On the vehicle body on one side of the seat, the buckle 9 is installed on the vehicle body on the other side of the seat, and the retracting device is located below the guide 8; the safety belt 14 is pulled out upwards from the retracting device Pass through the guide 8, then pass through the lock tongue 7, extend downwards and be fixed on the vehicle body. The lock tongue 7 is slidably mounted on the safety belt 14 and can be releasably plugged into the buckle 9 .

[0031] The detection of the safety buckle state includes a pressure sensor arranged under the seat to detect whether there ...

Abstract

The invention discloses a safety belt assembly capable of detecting the buckled state, which comprises a pressure sensor arranged on a seat, a detection switch for an insertion state, a warning device and a warning controller, and the pressure sensor, the detection switch and the warning device are electrically connected It is connected to the alarm controller; it also includes a retractor and a main frame, and the two ends of the retractor are integrally rotatably installed on the main frame through a rotating shaft, and a secondary retracting coil spring is also arranged between the retractor and the main frame. The retracting direction of the secondary retracting coil spring is opposite to that of the retracting coil spring; the length of the reversely wound safety belt on the housing matches the minimum pull-out length of the seat belt when it is correctly buckled; There is a distance sensor arranged radially toward the housing, and the distance sensor is electrically connected to the warning controller. The invention has the advantages of reasonable combination design, accurate and reliable detection means, the ability to identify the false insertion state, and the advantages of improving driving safety and the like.

Description

technical field [0001] The invention relates to the technical field of automobile safety belts, in particular to a safety belt assembly capable of detecting the fastening state. Background technique [0002] With the development of society and the improvement of economic level, the number of cars is also increasing year by year. Automobiles have brought great convenience to people's travel, but along with more and more automobiles on the road, traffic accidents occur from time to time. For ensuring the safety of drivers and passengers, safety belts are all provided on automobiles. According to the statistics of the Ministry of Communications, wearing a seat belt can reduce the death rate of an accident by 85%, so wearing a seat belt is extremely important. [0003] In order to remind the driver to fasten the safety belt during driving, a detection switch is usually provided at the buckle of the safety belt assembly to detect whether the deadbolt of the safety belt is correc...
