Description

Device for emergency release of door hinges

technical field

The invention provides a device for urgently releasing the hinge connection of a car door, which belongs to the technical field of auto parts.

Background technique

The door hinge is the main support that connects the door to the body. The revolving car door uses bolts as connecting parts. The bolt connection is simple and reliable. It firmly connects the body and the door, realizes the rotation of the door around the bolt axis, and completes the opening and closing of the door. The door hinges can be removed using a special tool.

Yet adopt bolt connection, even if there is special tool to dismantle hinge, it is also very difficult to remove hinge connection in emergency, and the operation of special tool is relatively difficult, and the occupant is difficult for grasping. When encountering an emergency (such as a damaged door lock or a door that is difficult to open due to deformation; when the car falls into the water and needs to prepare for escape), the traditional hinge connection method becomes an obstacle for the occupant to quickly open an escape channel.

Contents of the invention

The purpose of the present invention is to provide a device that can be used for emergency release of the hinged connection of the car door, which can quickly release the hinged connection between the door and the vehicle body in an emergency, so as to facilitate the quick removal of the door and quickly create an escape route.

The present invention realizes above-mentioned function and adopts following technical scheme:

The bolt connection in the traditional car door hinge connection is replaced by a pin connection. The invention includes a fixed support and a pin installed in the pin hole of the fixed support. It is characterized in that the bottom of the pin is equipped with a magnet, and the bottom of the pin hole of the fixed support is also Equipped with a magnet, the top plug passes through the fixed support and contacts the bottom of the pin, the spring is located on the upper part of the top plug, and the lower part of the top plug cooperates with the emergency trigger thrust device, both the top plug and the emergency trigger thrust device are located in the bracket, The seat and the fixed support are connected by threads, and the bracket is located under the fixed support. When the hinge connection needs to be released, press the switch of the emergency trigger thrust device, the emergency trigger thrust device generates a huge thrust, pushes the top plug to move upwards, and then uses the top plug to quickly eject the pin from the pin hole to release the hinge connection of the door.

The device for emergency release of the hinge connection of the car door: four holes are left on the upper part of the bracket, and internal threads are processed on the inner surface of the upper part.

The device for emergency release of the hinge connection of the car door: two magnet pieces are respectively installed on the bottom of the pin and the bottom of the pin hole of the fixed support, and the possible axial movement of the pin is constrained by the magnetic force of the magnet.

The device for emergency release of the hinge connection of the car door: the connection between the fixed support and the door frame is bolted or welded.

The device for urgently releasing the hinged connection of the car door: the power supply is the vehicle battery.

Its working principle is:

When the car is running normally, the magnetic force of the upper magnet sheet and the lower magnet sheet is used to ensure the normal cooperation between the pin and the pin hole, restrict the possible axial movement of the pin, and ensure the normal connection of the hinge. When a car accident occurs and the hinge connection of the car door needs to be released quickly, press the switch of the emergency trigger thrust device to immediately connect the electric squib circuit in the gas generator of the emergency trigger thrust device, ignite the ignition medium in the electric squib, and the flame will ignite. Ignite the propellant powder and the gas generating agent to generate a large amount of gas, which urgently triggers the air bag of the thrust device to expand rapidly upward, and at the same time pushes the top plug connected to it to move upward, so that the top plug has huge kinetic energy, and then the pin overcomes the friction resistance provided by the pin hole And the magnetic force between the two magnet pieces pushes the pin out of the pin hole quickly. Subsequently, the gas in the airbag of the emergency trigger thrust device is quickly discharged from the hole on the surface of the airbag, which helps the top plug to return to the bracket under the action of the spring, so that the hinged connection of the car door is released, and it is convenient to quickly remove the car door.

Compared with the prior art, the present invention has the advantage that in case of emergency, when it is necessary to quickly create an escape passage, the thrust provided by the emergency trigger thrust device can quickly push the pin out of the pin hole by using the top plug, thereby releasing the lock of the door hinge. connection for quick removal of the door. In addition, the present invention also has the advantage of simple operation.
