Embodiment 1

[0040] During the normal state, the locking bolt 9 stretches into the fixed frame (C) from the round hole 1' for placing the locking bolt on the movable frame (B), and the cross-sectional geometric shape of the seat used to close the seat is a hole 1 with rounded corners. The seat is locked in the center, and the metal block 5 used for the control lock will be locked under the action of the movable suction head return spring 4' (because the metal block 5 is integrated with the movable suction head 4 and the manual control hammer 2). The lock bolt 9 of the seat is sealed, and the locking work of the seat is completed.

[0041] When the car collides and reaches a certain strength, the automatic contactor installed on the car works, and the coil of the electromagnetic controller 3 in the special switch A set on the movable part of the seat bottom-the movable frame has current passing through, because the electromagnetic The direction of the electromagnetic force received by the m...

Embodiment 2

[0044] Remove the electromagnetic controller, suitably increase the weight of the metal block 5 ' that is used for the control lock bolt and increase the spring 15 that keeps the metal block 5 'normal state useful (the rest are the same as embodiment 1), in the absence of the electromagnetic controller , rely on the inertia of metal block 5 ' and manual control hammer 2 and also can open seat (being applicable to the car that can travel at high speed). The working process is as follows: when the car is running normally, the lock bolt 9 extends from the round hole 1' on the movable frame into the hole 1 whose cross section is a rounded rectangle on the fixed frame to lock the seat, increasing the weight of the metal block 5 'Under the action of the spring 15 used to maintain the normal state of the metal block 5', the latch 9 that has locked the seat is blocked, and the metal block 5' cannot be moved forward at the same time. When the collision force of the car reaches a certai...

Abstract

A special switch features that the electromagnetic controller is installed in such manner that its axial direction is just the longitudinal direction of car, so making the destroying inertia become the power to open the switch while changing the electric power of care to the electromagnetic force to open the switch. When an accident occurs, the inertia and electromagnetic force simultaneously act on a metal bock while can control locking bolt of chair to move it in longitudinal direction, so moving the locking bolt outward to release the chair.

Description

technical field [0001] The invention relates to a switch, in particular to a switch which is opened by inertial force and electromagnetic force and is suitable for the front seat of a car. Background technique [0002] There are many types of switches. At present, the common ones are electromagnetic switches, knife switches, password switches, and voice-activated switches. But there is no switch for the front safety seat of the car, because the car driver's safety seat is when the car has an accident and the collision force reaches a certain intensity, the safety seat will change from a fixed seat to a rear safe area. The movable seat, my father Liu Yunzhao invented this kind of seat in 1992, the patent number is: 92100620.9. After the improvement, he applied for a patent to the Chinese Patent Office on November 5, 1996 with the title "Multifunctional Car Front Safety Seat", which has also been approved, and the patent No. is: 96112075.4. He uses the electromagnetic switch...
