Problems solved by technology

However, there are still some drivers who are unwilling to wear seat belts and can easily trick the system by inserting a fake deadbolt into the buckle or inserting the deadbolt into the buckle with the webbing against the seat detection, burying a huge security risk

Embodiment 1

[0031] Example 1, such as figure 1 and figure 2 As shown, a car safety warning system includes a seat, a seat belt assembly matched with the seat, and an existing seat belt buckle detection system. The safety belt assembly includes a retractor assembly 1, a webbing 2, a lock tongue 3, a guide 8 and a buckle 9, and the retractor assembly 1 and the guide 8 are installed 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 retractor assembly 1 is located below the guide 8; the webbing 2 is pulled upwards from the retractor assembly 1 and passed through the The guide 8 extends downwards after passing through the dead bolt 3 and is fixed on the vehicle body. The lock tongue 3 is slidably mounted on the webbing 2 and can be releasably inserted into the lock buckle 9 .

[0032] The existing safety belt buckle detection system includes a pressure sensor arranged under the seat to detect whether there is a...

Embodiment 2

[0062] Embodiment 2: The main difference with Embodiment 1 is that, as Figure 7 As shown, the detection feature 5 is a metal strip attached to the webbing 2, and the metal strip extends from the middle of the webbing 2 to its inner end; the switch sensing device 7 is arranged on The proximity switch at the exit of the housing 11 corresponds to the position of the metal strip on the webbing passing through the exit.

[0063]Since the metal strap extends along the webbing toward its inner end, once the driver and occupant buckle the seat belt correctly, the webbing with the metal strap attached must pass through the exit, and the webbing at the exit must have a metal strap on it so that it can be accessed switch detected. When the safety belt is not buckled or directly buckled from the back of the driver and passengers, the webbing with the metal belt is still in the housing, so that there is no metal belt on the webbing at the exit of the housing, and the proximity switch can...

Abstract

The invention discloses an automobile safety warning system. The system comprises a pressure sensor used for detecting a riding state of a driver and passengers, a detection switch which is arranged in a lock catch of a safety belt and used for detecting an insertion state of a spring bolt, a warning device used for sending out a warning prompt, and a warning controller used for receiving a detection signal and sending the warning information according to the detection signal, the pressure sensor, the detection switch and the warning device are all electrically connected with the warning controller, the device further comprises a winder assembly, the winder assembly comprises a shell and a rotating shaft rotatably installed on the shell, a woven tape is wound on the rotating shaft, a detection feature object used for being detected is fixedly attached to the woven tape, the detection feature object is located in the middle of the woven tape, and a switch sensing device used for detecting whether the detection feature object passes or not is further arranged at an outlet of the shell and electrically connected with the warning controller. The device has advantages of being ingeniousin structural design, accurate and reliable in detection means, good in warning effect, beneficial to improving driving safety and the like.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile safety warning system. Background technique [0002] With the development of society and the improvement of economic level, the number of cars is also increasing year by year. Cars bring great convenience to our travel, but with more and more cars on the road, traffic accidents occur from time to time. To ensure the safety of drivers and passengers, seat belts are installed on cars. 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 correctly inserted into the buckle. However, there are still some drivers who are unwi...
