Abstract

The invention belongs to the technical field of automobile safety belts, and relates to a vehicle sensing locking device, a belt sensing locking device and a vehicle safety belt locking sensing device, wherein the vehicle sensing locking device comprises a frame, a belt winding barrel, a cylindrical permanent magnet, a coil, a magnetic conductive sphere body, a cam, an ejector rod, a motor and a controller. According to the vehicle sensing locking device, the belt sensing locking device and the vehicle safety belt locking sensing device, induction current is generated to control the rotation of the motor based on the electromagnetic induction principle, the principle is simple, the control is convenient, the locking function of the belt winding barrel can be accurately and rapidly achieved, the phenomenon of locking delay of a safety belt retractor in an emergency locking process is effectively solved, and compared with a prior mechanical locking device, the working reliability and safety of the safety belt retractor are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automobile seat belts, and in particular relates to a car sensor locking device, a belt sensor locking device and a car seat belt locking sensor device. Background technique [0002] At present, automobiles have become an indispensable means of transportation in life, and the safety of automobiles has been paid more and more attention by consumers and automobile manufacturers. As a necessary safety device on a car, the seat belt can firmly tie the occupant to the seat when the vehicle collides or emergency brakes, prevents secondary collisions, and avoids or reduces the degree of injury to the occupants. In order to ensure that the webbing of the car seat belt will not be pulled out during vehicle collision or emergency braking, the seat belt retractor is generally provided with a locking device. The traditional locking device is generally realized by using a mechanical structure. The steel ball senses t...
