Detailed Description
The utility model provides a hasp structure of electron safety belt. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
A buckle structure of an electronic safety belt, as shown in fig. 1 to 4, includes a buckle 1 disposed at a free end of the safety belt, and a locking base 2 for locking and releasing the buckle.
A limiting clamping groove 3 is arranged in the locking base 2, a telescopic elastic mechanism 4 is arranged on one side wall of the limiting clamping groove 3, an electromagnetic adsorption end 5 is arranged on the other side wall of the limiting clamping groove 3, and a locking block 6 which penetrates through the lock catch 1 and is attracted with the electromagnetic adsorption end is arranged on the telescopic elastic mechanism 4.
Specifically, the electromagnetic absorption end 5 has an electrical circuit that is communicated with the power supply system of the vehicle, and the electrical circuit belongs to a simple power supply circuit, and only needs to satisfy the power supply requirement of the electromagnetic absorption end 5, which is not described herein again.
Between the car starts to go up the electricity, carry out the preassembleing of hasp 1 and lock position base 2 earlier, directly peg graft hasp 1 in spacing draw-in groove 3 promptly, realize hasp 1 and the preliminary locking of lock position base 2 this moment.
After the automobile starts and is powered on, the electromagnetic adsorption end 5 is powered on to generate adsorption force on the locking block 6, so that the adsorption locking effect under the power-on state is met, the situation that the lock catch 1 is loosened due to false triggering cannot be generated, the lock catch 6 can be loosened only under the power-off state of the electromagnetic adsorption end 5, and therefore safety is improved.
In one embodiment, the elastic mechanism 4 comprises a fixed member 41 fixedly disposed in the capture base 2, and an elastic expansion member 42 is disposed between the fixed member 41 and the lock block 6. The resilient bellows 42 is a compression spring. More finely, the end face of the locking piece towards the electromagnetic absorption end is provided with a top chamfer inclined plane and a bottom chamfer inclined plane.
Specifically speaking is clear, before electromagnetism absorption end 5 goes up the electricity, hasp 1 can realize free buckle and pull out from the operation in spacing draw-in groove 3, specifically, at the grafting in-process, hasp 1 produces pressure to top chamfer inclined plane, thereby locking piece 6 deviates from 5 direction displacements of electromagnetism absorption end oppression spring, when hasp 1 is pegged graft and is targetting in place, thereby locking piece 6 receives spring deformation to reset and passes the lockhole realization locking of hasp 1, the resilience force of safety belt is not enough to drive locking piece 6 displacements this moment.
When carrying out the hasp 1 pine and taking off, grip the safety belt and carry and draw to the realization is to the drive of locking piece 6, can realize breaking away from the operation of spacing draw-in groove 3.
And electromagnetic adsorption end 5 is under the power-on state, possesses great earth magnetism adsorption affinity between electromagnetic adsorption end 5 and the locking piece 6, and the lock catch 1 lock solid is in spacing draw-in groove 3 this moment, and the pine also can not appear taking off even if the great impact force appears.
In one embodiment, the power-off button 7 is disposed on the electrical circuit of the electromagnetic attraction terminal 5, and the power-off button 7 is disposed on the capture base 2.
Specifically speaking, the power-off button 7 is used as a temporary buckle and an emergency, specifically speaking, when the power-off button 7 is pressed, the electromagnetic adsorption end 5 is demagnetized, so that the electromagnetic adsorption end can be released from the lock block 6, and at the moment, the insertion and extraction operation of the lock catch 1 can be realized.
In addition, when the child touched outage button 7 by mistake, because flexible elastic mechanism 4 possesses certain elasticity locking effect, the difficult 1 pine of production hasp takes off the phenomenon, in addition, after outage button 7 triggers, electromagnetism absorption end 5 still possesses certain earth magnetism and subsides the time, probably about 5 ~ 8 seconds, and electromagnetism absorption end 5 still has certain earth magnetism adsorptivity this time quantum, can effectively avoid the pine to take off.
Can discover through the above description, the utility model relates to an electronic safety belt's hasp structure adopts flexible elastic mechanism to adsorb the end with the electromagnetism and mutually supports, can realize elasticity locking in advance and go up the effect of electricity fixed locking, and the spurious triggering when effectively preventing children from using loosens the buckle phenomenon, has improved the safety in utilization of safety belt. Possess the design of outage button, the electromagnetism when can realize the car power-on state adsorbs the end power-off control, and the manual pine that easily emergency is under looses and uses. The overall design is simple and ingenious, and the phenomenon of loosening of the misoperation lock catch is effectively reduced.
The above technical solutions of the present invention have been fully described, and it should be noted that the present invention is not limited by the above description, and all technical solutions formed by equivalent transformation or equivalent transformation adopted by the spirit of the present invention in the aspects of structure, method or function by those of ordinary skill in the art all fall within the protection scope of the present invention.
