Safety belt warning system

Abstract

The invention discloses a safety belt warning system, belonging to the technical field of security accessories of automobiles. The safety belt warning system comprises a winding device, a safety belt braid, a safety belt lock assembly and a safety belt reminder, wherein the safety belt lock assembly comprises a slot and a plug buckle; and the safety belt reminder comprises a pressure sensor, a signal detection device, a shifting piece, a controller and a warning device and is connected in a buckling manner. According to the safety belt warning system, the behavior of a driver that the warning device is cheated by virtue of properties of a traditional plug buckle can be greatly improved, and the behavior that the driver uses a safety belt to penetrate through the space between the back of a passenger and a seat or penetrate from the back of the seat and inserts the safety belt into a safety belt slot can be further avoided; and by virtue of the peculiarity of an assembly structure and the difference of key tooth slots, the accidental falling of the safety belt plug buckle is avoided, and sundries cannot enter an opening of the safety belt slot. The safety belt warning system is peculiar and simple in structure, difficult to replace, low in interhancgeability rate and manufacturing cost, safe, reliable and easy to popularize and use, and damaged parts are easily changed.

Description

technical field [0001] The invention relates to the technical field of automobile safety accessories, more specifically, to a safety belt warning system. Background technique [0002] With the popularity and popularization of automobile products, people pay more and more attention to the safety factor of automobiles. The safety belt of automobiles is an important safety guarantee to protect people from accidents such as automobile collisions. Good seat belts can significantly reduce casualties in accidents. Therefore, the setting of seat belts is becoming more and more important. However, at present, many drivers and passengers have a fluke mentality, thinking that the speed will not be too high, and there is no chance to use them. Seat belt, when the car itself has an alarm sound and the instrument alarm shows that the driving "seat belt is not fastened" prompt, still do not wear the seat belt during driving, or use the versatility of the seat belt buckle, and choose a meta...

Problems solved by technology

This application modified the seat belt buckle, and stored the minimum angle value in the controller. As long as the angle of rotation of the buckle seat exceeds this angle value after the seat belt is fastened, the controller will judge that the seat belt has been fastened. However, if the buckle of the passenger seat is inserted into the slot on the main driver's seat, and the object is placed on the seat to cause the angle of the rear seat belt to rotate, its shortcomings will be obvious, so it can be seen This application does not change the general characteristics of the seat belt buckle, it is not unique and irreplaceable, and the structural parts of the seat belt buckle in this application are almost all mechanical components, resulting in the components in the buckle. It is easy to be worn and damaged during use, which makes the maintenance or replacement cost higher. At the same time, the seat belt buckle has been changed more in this application, which will change the force relationship in the buckle and greatly reduce the safety performance of the seat belt.
