Device for emergent removing door hinge connections

Abstract

The invention provides a device for emergent removing door hinge connections. The device for emergent removing the door hinge connections comprises a fixed support and a pin mounted in a pin hole of the fixed support, the device is characterized in that the bottom of the pin is provided with a magnet, the bottom of the pin hole of the fixed support is also provided with a magnet, a top plug passes through the fixed support and is contacted with the bottom of the pin, a spring is located at the upper portion of the top plug, the lower portion of the top plug is matched with an emergency trigger thrust device, both of the top plug and the emergency trigger thrust device are located in a bracket, the bracket and the fixed support are connected in a threaded mode, the bracket is located under the fixed support, and a rubber cushion is arranged between the bracket and the fixed support. According to the device for emergent removing the door hinge connections, the magnets are used to restrain possible axial movement of the pin in normal car driving process, when the hinged connection needs to be removed, the emergency trigger thrust device generates great thrust and pushes the top plug to move upward rapidly, therefore the top plug is used for the pin to overcome axial restriction of the magnets and disengage the pin hole, so that vehicle door hinge connections are removed, and the vehicle door is easy to be disassembled. The device for emergent removing the door hinge connections can quickly remove the vehicle door hinge connections, make it convenient to disassemble the vehicle door, and quickly create an escape passage.

Description

technical field [0001] 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 [0002] 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. [0003] 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 ...

Problems solved by technology

[0003] However, if the bolt connection is used, even if there is a special tool to disassemble the hinge, it is very difficult to remove the hinge connection in an emergency, and the operation of the special tool is difficult, and it is difficult for the occupant to grasp it.

When encountering an emergency (such as the door lock is damaged or the door is difficult to open due to the deformation of the door; when the car falls into the water and needs to prepare for escape), the traditional hinge connection method becomes an obstacle for the occupants to quickly open the escape channel.
