Embodiment 1

[0025] in such as figure 1 figure 2 In the shown embodiment 1, a car battery safety device is connected to the wiring terminals of the car battery. The housing is a cylindrical structure, including a left housing 12 and a right housing 13, and the left housing and the right housing are screwed together; the power-off mechanism includes an electromagnetic coil 1, a fixed contact, and Head 2 and moving contact 3, the center of the housing is provided with a fixed column 4 and a movable column 5, the central axis of the fixed column and the central axis of the movable column are on the same straight line, one end of the fixed column and one end of the housing The side is fixed, and the electromagnetic coil is fixed on the other side of the housing through an open iron core 7 with a central hole 6; the iron core is a cylindrical structure, and the center of the cylindrical iron core is provided with a circular Central column 14, the central hole is arranged in the center of the...

Embodiment 2

[0029] There are 8 elastic fingers in embodiment 2, which are evenly distributed around the central axis of the elastic stop bowl, and the longitudinal section of the elastic fingers is trapezoidal (see image 3 ), the thickness of the base of the elastic finger is greater than the thickness of the free end of the elastic finger, the width of the base of the elastic finger is greater than the width of the free end of the elastic finger, and the rest are the same as in Example 1.

Embodiment 3

[0031] A tension spring 21 is provided between the fixed partition and the armature plate of embodiment 3 (see Figure 4 ), the two ends of the extension spring are respectively fixedly connected with the fixed partition and the armature plate, and the rest are the same as those in Embodiment 1 or Embodiment 2.

[0032] The automobile battery safety device of the present invention does not work at ordinary times, and the armature plate is located at the side of the elastic retaining bowl close to the fixed column and is close to the elastic finger, so the fixed contact and the movable contact are in contact conduction state at ordinary times. After accidents such as strong collisions occurred in the automobile, the corresponding anti-collision system of the vehicle sent a safety airbag ignition signal, and the automobile safety airbag control unit provided a control signal to the automobile storage battery safety device of the present invention at this time, and the electromagn...

Abstract

The invention discloses a vehicle storage battery safety device, comprising a rigid shell and an outage mechanism arranged in the shell; the outage mechanism comprises an electromagnetic coil capable of connecting with a vehicle safety airbag control unit, a static contact and a moving contact; the static contact is arranged at one end of a fixing post; the moving contact is arranged at the opposite end of a moving post of which the other end is glidingly arranged in a center hole of an opening iron core of the electromagnetic coil; a round armature plate is arranged in the middle of the moving post; an elastic check bowl is arranged in the middle of the shell and is provided with elastic fingers in annular distribution and inclined to one side of the electromagnetic coil; the dangling end of each elastic finger forms an armature hole of which the diameter is smaller than the armature plate. The vehicle storage battery safety device effectively solves the problems of low reliability and slow reaction speed of a vehicle collision outage protection device in the prior art, and the vehicle storage battery safety device is simple in structure, high in reliability, fast in action speed and has very high practical value.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile storage battery safety device which is opened in an emergency state of the automobile. Background technique [0002] After a car accident such as a strong collision, it is prone to oil leaks or oil leakage from the mailbox. If the power supply of the accident vehicle is not cut off in time, the short circuit or other circuit failures that may accompany the car accident may cause sparks or burns, which will easily cause car fires. and other more serious secondary accidents. In the prior art, there is also a power-off method similar to cutting off the power supply through contactors, relays, etc., but because the contactors, relays, etc. of the car may be impacted and stuck after a strong collision, even if the power is cut off, it may not be able to turn off the power. Its contacts are broken, so this method of power off is very unreliable. The pu...
