[0002] The pre-tensioned seat belt is a kind of car seat belt. The difference from other seat belts is that a pre-tensioner is added to the pre-tensioned seat belt. The pre-tensioner can sense a certain impact during a collision. The gas generating agent, etc. generate an action to instantly pull the seat belt closer. Although this pre-tensioned seat belt can improve safety performance, the gas generating agent needs to be filled by professionals after use, which is very troublesome, and some electric ones The power supply of the pre-tensioned seat belt is powered by the body battery. Once the circuit of the body is damaged, the pre-tensioned seat belt will not be able to operate and will not play the role of safety protection.

The invention discloses a charging device for a seat belt buckle with an early warning function. The charging device comprises a seat belt retractor, a seat belt is wound on the seat belt retractor, astorage battery component is arranged in a battery protecting shell, a speed reducer is connected to an output end of a motor which is arranged at the upper end of an L-shaped support, and a rotatingplate is connected to an output end of the speed reducer. The upper end of an electromagnet support is provided with an electromagnet, the outer wall of a first guide roller is provided with throughholes, and insertion columns are slidably inserted into the through holes. The charging device has advantages that the motor is arranged on one side of the seat belt retractor, the electromagnet repels a magnet plate after being electrified, then the insertion columns protrudes to clamp the seat belt, the motor acts quickly to enable rotation of the rotating plate to quickly retract part of the seat belt, and thus, the length of the seat belt tied to the body of a user is reduced, and the protective performance is improved; by an independent power supply device, dependency on automobile intrinsic power supply is avoided, and failure in safety protection due to failure in action of a pre-tensioned seat belt when an automobile circuit is damaged can be avoided.
