Electromagnetic induction type anti-collision safety helmet belt

Abstract

The invention relates to an automobile safety device with active and passive characteristics and belongs to the field of traffic safety equipment. In the safety device, a safety belt tightening device is arranged at a headrest; an exposed end of the safety belt is connected with a safety helmet through a latch and a pin; an electromagnet and a brake mechanism which is controlled by an electromagnet coil are additionally arranged on the safety belt tightening device; an electromagnetic sensor is arranged at a safety belt reel of the safety belt tightening device and is connected to an input end of a microcomputer through a signal wire; and the output of the microcomputer is connected with an automotive engine rotating speed electric control mechanism, a brake electric control mechanism and the electromagnet coil of the safety belt tightening device. The safety device can replace an air bag, timely discover behavior disorder of a driver, timely prompt or brake, protect head safety of the driver and other passengers and prevent cervical vertebra of the driver and other passengers from being subjected to whiplash injury during an accident, and is low in cost and high in reliability.

Description

Technical field [0001] The invention relates to an automobile safety device and belongs to the field of traffic safety equipment. Background technique [0002] Driving safety is the first consideration when driving a car. For car safety devices, they are divided into active safety devices and passive safety devices. At present, all cars are equipped with seat belts and seat head restraints. Usually, the seats are equipped with three-point seat belts to position the human body on the seat. Although existing cars are equipped with seat belts, when a car accident occurs, the head will still be severely injured due to the inertial force. For this reason, some cars are equipped with airbags. However, the airbag has the following defects: 1. Due to the poor quality of some products, the airbag cannot be opened in time when a car accident occurs; 2. In a high-speed crash, even if the airbag is opened, the driver's head will still be hit hard. The airbag goes on and then rebounds...
