Emergency unlocking system for automobile door

Abstract

The invention discloses an automobile door emergency unlocking system, and belongs to the technical field of automobile safety technology background technology. The existing automobile door emergency unlocking system has technical defects. The possibility that an automobile door fails to unlock under the conditions of automobile power loss, wire harness open circuit, electric appliance faults and the like caused by an automobile accident exists, and great hidden danger is caused to the personal safety of passengers. According to the solution, 1, each vehicle door is provided with a small-capacity energy storage standby power supply, and normal power supply of an unlocking motor is guaranteed under the condition that a vehicle main power supply completely fails; 2, each door is provided with an independent unlocking control panel, so that the door is automatically unlocked under the condition that a vehicle main control computer is damaged and fails or a wire harness is fully broken and loses communication with the control panel; and 3, an emergency physical switch is arranged between the small-capacity energy storage standby power supply and the unlocking motor, so that the vehicle door can still be unlocked under the condition that the main power supply, the main computer, the wiring harness and the control panel are completely damaged. The method is suitable for automobile manufacturing and automobile modification technology upgrading.

Description

Technical Field

[0001] Automotive safety technology. Background Art

[0002] At present, the number of cars in society is large, and traveling by car has become the main mode of transportation. Car accidents also occur frequently in complex and crowded traffic environments. From many accident cases, we can see that many cars cannot unlock their doors when they encounter accidents or technical failures, resulting in the occupants of the car being unable to save themselves and the people outside the car being unable to rescue them, causing a lot of unnecessary personal injuries. Most cars are now equipped with central locking, and unlocking relies entirely on the central control computer to issue instructions, with a single power supply. In an emergency, power outages, damage to the central control computer, or a broken wiring harness will cause the emergency door unlocking to fail. The present invention can avoid the failure of emergency door unlocking caused by power outages, damage to the central control computer, or a broken wiring harness. The multiple redundant safety designs can greatly increase the chances of people trapped in the car being rescued. Summary of the Invention

[0003] The vehicle door emergency unlocking system includes: ① a small-capacity energy storage backup power supply to ensure door unlocking in the event of a main power outage; ② an independent unlocking control panel to ensure door unlocking in the event of a loss of communication with the central control computer; and ③ a physical emergency switch to ensure door unlocking in the event of a complete electronic circuit failure.

[0004] Specific implementation methods: ① Each door of the vehicle is equipped with a small-capacity energy storage backup power supply. Under normal circumstances, it is fully charged and on standby, and automatically powers the emergency unlocking system in the event of a main power outage. ② Each door is equipped with an independent unlocking control panel, which receives unlocking and locking commands from the main control computer under normal circumstances and automatically unlocks the door in the event of an abnormal loss of communication with the central control computer. ③ A physical switch without any electronic components is configured between the small-capacity energy storage backup power supply and the unlocking motor to unlock the door in the event of a main power outage, damage to the central control computer, a wiring harness break, or damage to the independent unlocking control panel. In an emergency, the emergency unlocking system of each door can operate independently, and even if some doors are damaged, it will not affect the normal unlocking of other doors.

Claims

1. A car door emergency unlocking system, comprising a small-capacity energy storage backup power supply, an independent unlocking control panel, and a physical emergency switch, characterized by: The car door can still be unlocked in an emergency even if the car's main power supply is interrupted, the central control computer is damaged, the wiring harness is broken, or the independent unlocking control panel is damaged.

2. The automobile door emergency unlocking system according to claim 1, characterized in that: Independent of the vehicle's main power supply, each door is equipped with a small-capacity energy storage backup power supply to ensure the normal operation of the vehicle's door emergency unlocking system when the main power supply is interrupted.

3. The automobile door emergency unlocking system according to claim 2, characterized in that: Each door is equipped with an independent unlocking control panel, which receives unlocking and locking commands from the main control computer under normal circumstances, and automatically unlocks the door when communication with the central control computer is abnormally lost.

4. The automobile door emergency unlocking system according to claim 3, characterized in that: A physical switch without any electronic components is configured between the small-capacity energy storage backup power supply and the unlocking motor. The door can still be unlocked in an emergency when the main power supply of the car is interrupted, the central control computer is damaged, the wiring harness is broken, or the independent unlocking control panel is damaged.
