Automatic fusing device and method for safety belt and vehicle

Abstract

The invention discloses an automatic fusing device and method for a safety belt and a vehicle, the safety belt automatic fusing device comprises a safety belt, a lock pin, a lock catch and a safety belt retractor, a braid hole is formed in the lock pin, and a thrust block is arranged in the lock catch; the device also comprises a heating wire, a safety airbag controller, a power module and a BCM body controller for controlling the power module be on and off. The safety airbag controller is connected with the BCM body controller, a first binding post is arranged at the lower end of a spring bolt of the lock pin, and the two ends of the electric heating wire are connected with the power module and the first binding post. A second binding post used for abutting against the first binding post is arranged on the top face of the thrust block. The BCM body controller and the second binding post are connected with the power module, and the electric heating wire is arranged in the braid hole and used for fusing the safety belt in the braid hole. According to the automatic fusing device for the safety belt, the tied safety belt is automatically electrified, heated and rapidly fused, the restraint of the safety belt on people is rapidly eliminated, and trapped passengers in a passenger compartment are rescued.

Description

technical field [0001] The invention relates to the technical field of vehicle safety belts, in particular to a safety belt automatic fuse device, a method thereof, and a vehicle. Background technique [0002] Vehicle seat belts are widely equipped on various types of cars because they can effectively restrict the position of the occupant and avoid secondary collisions between the occupant and objects inside and outside the vehicle. Existing vehicle seat belts are composed of retractors, seat belts, lock pins, and buckles. Although seat belts can effectively prevent the occupants from secondary collisions with other objects and greatly improve the safety of the occupants, the damage to the seat belt buckle and unlocking device after the collision prevents the occupants from being able to get rid of the restraints of the seat belts in time and escape the passenger compartment smoothly. The safety of the occupants constitutes a certain threat. For example, when the safety bu...

Problems solved by technology

However, this structure has the following problems: First, it is prone to false triggering. For example, if the temperature inside the car increases due to weather changes, or the occupant smokes, etc., as long as the device is installed, the safety belt that is not in use will be falsely triggered and fused; The second is that it is easy to cause secondary damage. For example, when the gunpowder burns, it will cause secondary damage to the occupants, and it is also easy to cause the plastic parts near the device to catch fire, resulting in more property losses. , poor aesthetics
