A car door anti-locking device for automatically bouncing and unlocking mechanical locks

Abstract

The invention discloses a vehicle door anti-lock device with automatic bounce and unlock of a mechanical lock. The structure of the vehicle door anti-lock device comprises a vehicle door, a mechanicallock control device and an electronic lock control device, wherein the mechanical lock control device is provided with a transmission motor, a transmission gear and a mechanical lock bouncing device;the transmission motor is riveted and connected inside the vehicle door through bolts; the electronic lock control device is provided with a hydraulic ejector rod device and an anti-lock device; thehydraulic ejector rod device is vertically welded above the anti-lock device; and the anti-lock device is vertically welded on the inner wall of the vehicle door. The vehicle door anti-lock device hasthe beneficial effects that after circuit is powered off, the work of the transmission gear is stopped, so that the mechanical lock bouncing device is driven to work, the bolt is driven to pop out, and the mechanical lock is unlocked at the same time, so that passengers in the vehicle do not need to pull the bolt to unlock, the vehicle door can be pushed open in time to escape under the conditionthat the water pressure inside and outside the vehicle is balanced, and the accident that the passengers drown due to ignorance of the action of the bolt is avoided.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a car door anti-locking device for automatically bouncing and unlocking a mechanical lock. Background technique [0002] Cars are a common tool for daily transportation. Although cars have generally entered every household, there are still accidents of drowning due to cars falling into rivers every year. After the car falls into the river, the air inside the car will cause water Squeeze the door, and the gravity can reach 150 kg. Therefore, when the water pressure inside and outside the car has not reached balance, the door cannot be opened. However, when falling into the river, the people in the car will generally panic, and their strength and oxygen will be exhausted before the water pressure is balanced, so it is difficult to support the escape after the water pressure is balanced. [0003] Aiming at the current door anti-locking equipment, a relative solution has been formulated fo...

AI Technical Summary

Problems solved by technology

[0004] In view of the current situation of cars falling into the river, mechanical locks are installed inside the general car. Even if the car is flooded or the power system is damaged, the door can be opened through the mechanical lock. The general mechanical lock is a latch device. The door can be opened by pulling it up, but this safety device has not been popularized. Many people do not know the function of the bolt, which leads to delays in the best escape time. Therefore, a device that automatically pops out the bolt to open the door lock after a power failure is needed
