Description

The invention relates to the field of electrical equipment of vehicles and can be used for emergency, automatic shutdown of the battery in order to prevent fire, short circuit and other dangerous situations.

A device for opening the battery [AC No. 1699833 B60R 16/02 from 12/23/1991]. The device consists of a button, a light bulb, an ignition switch, resistors, capacitors, a thyristor, a battery, a relay, diodes, a pulse transformer, a device for mounting on battery terminals, a disconnecting device, sensors, triggers, and safety devices.

The disadvantage of this device is the possibility of sparking and heating when the relay and other nodes are activated, as well as the low reliability of the circuit power off.

Closest to the proposed invention is an automatic electronic battery switch [Patent RU 2350494 B60R 16/02 of 03/27/2009].

The automatic electronic switch of the battery contains a device for mounting on battery terminals, a disconnecting device, sensors, triggers, safety devices, a resistor, a transistor, and a self-healing fuse.

The disadvantage of this device is the possibility of sparking when triggered by sensors and triggers, the low reliability of the de-energized circuit, as well as its heating.

The objective of the invention is the creation of an emergency automatic circuit breaker for the battery, eliminating sparking and heating of the main elements of the vehicle electrical system, which has high reliability of de-energizing the circuit.

The problem is achieved in that in the emergency automatic battery switch containing the device for mounting on the battery terminals, disconnecting devices, sensors, triggers, safety devices, the device for mounting on the battery terminals is made in the form of a rectangular block, consisting of two sections having the possibility of relative movement, in one of the sections of the block a cylinder with compressed gas is installed, connected by a flexible pipe to cylindrical chambers, laid in each section of the rectangular block coaxially with the terminals on which the contacting bushings with movable pistons are mounted, and magnetic and mechanical locking devices are located in the upper parts of the cylindrical chambers, the trigger mechanism being made in the form of an electromagnetic valve.

In FIG. 1 is a diagram of a battery emergency circuit breaker.

The automatic emergency battery switch contains a device for mounting on the battery terminals, made in the form of a rectangular block, consisting of two sections 1 and 2, with the possibility of relative movement, opening device 3, sensors 4, triggers 5. In section 1 there is a cylinder with a compressed gas 6, connected by a flexible conduit 7 with cylindrical chambers 8 located in each section of the rectangular block coaxially to the terminals 9, on which the contact sleeves 10 are mounted with movable rhinoceros 11. In the upper parts of the cylindrical chambers 8 are magnetic 12 and mechanical 13 locking device. The trigger mechanism is made in the form of an electromagnetic valve 14. To fasten sections 1 and 2 of the rectangular block to the battery, belts 15 are provided.

Automatic emergency switch battery operates as follows.

Initially, the device is connected to the battery, through the contact of the movable pistons 11 with the contacting bushings 10, which are worn on the terminals of the battery 16.

In the event of an emergency (head-on collision, coup, etc.) or short circuit, sensors 4 (shock, accelerometers, etc. installed in the car and connected to the electronic control unit and the device itself) send a signal to the electronic control unit of the car, which delivers to the electromagnetic valve 14, which opens the flow of compressed gas through the flexible pipe 7, into the cylindrical chambers. Where there is a sharp increase in pressure, leading to the raising of the movable piston 11 in the upper position. Here it is fixed by magnetic holders 12 and mechanical latches 13. The formed gap between the piston 11 and the contacting sleeve 10 reliably opens the electrical network (disconnects the battery).

Disconnecting both battery terminals almost completely prevents the occurrence of a short circuit in case of damage to the rectangular block (case) in the event of an accident.

The presence of double piston fixation in the upper position with the help of magnetic holders and mechanical latches also helps to increase reliable battery disconnection.

The execution of a rectangular block (case) of the device in the form of two sections with the possibility of relative movement makes it possible to use it with various types of batteries.

The use of compressed gas enclosed in a cylinder as an energy source prevents heating and sparking during operation of the device.

In addition, in the event of a device being triggered, it is possible to replace the used cylinder with a new one.

The cylindrical shape of the chambers 8 simplifies the attachment of the emergency battery circuit breaker to the battery terminals, and this form is easier to manufacture in mass production.

The presence of a spring contributes to the constant contact of the piston with the terminals, which is necessary when driving a car.

With a relatively simple design, the proposed emergency automatic battery switch reliably disconnects the battery from the vehicle network, which prevents the occurrence of fire and other dangerous situations.
