Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] figure 1 It is the layout of the multi-function door micro-explosion system on the vehicle body. The driver's button is arranged on the driver's console, the driver's button can control the door pneumatic device through the vehicle electronic control system, and the pneumatic device controls the opening state of the car door. An emergency button is arranged above the pneumatic device, and the pneumatic device can also be activated by pressing the emergency button in an emergency to control the opening state of the car door. When the pneumatic device is working, the door sensor circuit will be connected, and the power supply of the door sensor circuit is installed above the emergency button. When the door sensor detects that the gap between the door and the door frame is too small to open the door, it sends a signal to the controller. The controller is arran...

Abstract

The invention discloses a multifunctional car door micro-explosion system. When an emergency situation such as a fire, collision, falling into water or falling off a cliff occurs in a passenger car, adoor of the passenger car cannot be opened, and the micro-explosion system is triggered to act to open the door. The system is provided with a second set of mechanical door opening device. At the same time, an own two-way hydraulic damping device of the system can absorb part of energy of front impact and reduces structural deformation of the car. When a vehicle-mounted sensor detects the emergency situation or a driver presses a door opening button, a door opening system is operated and a car door sensor detects whether the door is open or not. When the door fails to open, the micro-explosive device is triggered to act to assist the door to fully open. When a control system of the micro-explosive device fails, the driver and passengers can open the door by operating a mechanical device.The multifunctional car door micro-explosion system can ensure the passengers to escape quickly, and the advantages of reliable escape and high realization are achieved.

Description

technical field [0001] The invention belongs to the technical field of emergency evacuation of passenger cars, and in particular relates to a multifunctional vehicle door micro-explosion system. Background technique [0002] In the past major traffic accidents of passenger cars, the investigation found that when a fire broke out in the engine compartment of a passenger car or inside the compartment, it was difficult for the driver to detect it at the first time, which made the drivers and passengers miss the best escape time at the initial stage of the fire. When the passenger car fell into the water, due to the large water pressure difference inside and outside the car, before the car was flooded with water, the door could not be opened due to water pressure restrictions, and personnel could not open the door in a short time to escape. When a collision accident occurs in a bus, the driver and passengers cannot operate the emergency door to open smoothly due to injuries, and...
