Problems solved by technology

However, in the process of driving, once an accident occurs, the driver and passenger are often injured before they react, or the driver and passenger have been trapped in the car because they have been panicked and have not been able to get rid of their seat belts, resulting in injury or death. If the vehicle falls into the river, it is more likely that the driver and passengers will not be able to disengage their seat belts in time, resulting in suffocation and death

Embodiment Construction

[0034] The invention includes a motor, a backup power supply and five switches connected with the motor. The backup power supply is in a charging state at ordinary times. Buckle provides electrical energy.

[0035] working principle:

[0036] In the normal state, the cam driven by the motor is at the initial position, and the five switches are all in the disconnected state. When the buckle of the seat belt is inserted into the buckle, the buckle pushes the tongue inside the buckle, and the switch at the bottom of the tongue is activated. When it is connected, the moving lock tongue drives the connecting rod to push the spring at the same time. When the connecting rod is pushed beyond the vertical position, the force of the spring makes the pressure rod exert downward pressure on the lock plate, and the lock plate is pressed into the lock of the buckle. In the hole, the front end of the lock plate falls on the cam at this time; when the lock is unlocked, pull the handle, and t...

Abstract

The invention relates to an automatic automobile safety belt release device which has the structure that a motor is connected with a cam as well as a hand shank and lock plate connecting shaft in a unidirectional interlock way, a locking dog can slide on a bracket, a connecting rod is connected with the locking dog, and the other end thereof is connected with a compressive bar; the compressive bar is arranged on a slideway, a pressure spring is connected with a lock plate, and the other end thereof is connected with the connecting rod; a power supply is connected with the motor, the other endof the motor is connected with K4 which is connected with K5 in parallel; K1 and K3 are connected with K2 in parallel, the K4 and the K5 are serially connected with the K1, the K2 and the K3 which are connected in parallel after being connected in parallel, the output is connected with the other end of the power supply; the K5 is arranged at the front bottom of the locking dog, the K1 is connected with the handle shank in a contacting way, the cam is arranged below the lock plate, and the K2 and the K4 are arranged below the cam. The device solves the danger problem when timely manual releaseis impossible, which is caused by that only manual release is possible, and automatic release is impossible. A safety belt release switch can be arranged on the most convenient position inside the automobile and is not limited on the lock catch beside the seat; furthermore, the manual unlocking manner is remained and is carried out simultaneously with electromotion unlocking so as to reduce releasing force, thus having faster and more accurate operation in an emergency.

Description

technical field [0001] The invention relates to an automobile safety belt, in particular to an electric release device for the automobile safety belt. Background technique [0002] Before the present invention, the safety belts of automobiles at home and abroad are all manually disengaged, no matter how the vehicle type, grade, brand and car price are, and the unlocking mode of the lock buckle is all push-type. However, in the process of driving, once an accident occurs, the driver and passenger are often injured before they react, or the driver and passenger have been trapped in the car because they have been panicked and have not been able to get rid of their seat belts, resulting in injury or death. If the vehicle falls into the river, it is more likely that the driver and passengers will not be able to disengage their seat belts in time, resulting in suffocation and death. Contents of the invention [0003] Purpose of the present invention will overcome above-mentione...
