A safety device for preventing side impact vehicle door from opening

Abstract

The invention provides a safety device for preventing the opening of a side collision door, which belongs to the technical field of auto parts. It solves the problem that the car door will be opened by mistake when a side collision occurs in the existing automobile, causing two injuries to the occupants. The safety device for preventing the opening of the side impact car door, the car includes the car door, the car door is provided with a car lock, the car lock includes an inner locking twist, the safety device includes a deformation sensing rod provided in the car door, the inner end of the deformation sensing rod and the inner lock Anti-twist linkage, the outer end of the deformation sensing rod abuts against the outer panel of the door or there is a gap between the outer end of the deformation sensing rod and the outer panel of the door, when the outer panel of the door moves inward, the outer panel of the door pushes The deformation sensing rod makes the deformation sensing rod drive the inner locking twist to lock the car door. The safety device for preventing side collision doors from opening has the advantages of high transmission sensitivity and good safety performance.

Description

technical field [0001] The invention belongs to the technical field of auto parts and relates to a safety device for preventing the opening of a side collision door. Background technique [0002] With the progress of society and the improvement of people's living standards, automobiles have become more and more common means of transportation for people to go out and travel, and people are paying more and more attention to the safety and comfort of automobiles. [0003] Automobile comprises car door, and car door comprises the outer panel that is positioned at outer side, and car lock is arranged in the car door, and car lock comprises outward opening swing arm, inner locking knob and dead bolt, and the outer plate of car door is provided with outward opening handle, and outward opening handle passes through The inertia block and the push rod are connected with the outward swing arm, that is, when the outward swing handle is opened, the outward swing arm is driven downward th...

Problems solved by technology

[0004] When the inner locking switch is not pulled and the inner locking knob is in the locked position, when the outward opening handle is opened, it will eventually drive the outward opening swing arm to rotate downward through a series of transmissions to unlock. When the car has a side collision, this structure There are three types of mechanisms that may be opened by mistake: 1. The deformation and indentation of the middle part of the door drive the outer door handle to move downward as a whole, thereby driving the push lever to move downward to unlock the lock; 2. The indentation of the door directly hits the outward opening swing arm and the push lever Or the moving parts such as the counterweight may cause the outward swing arm to move downward and unlock the lock. 3. The local deformation of the outward swing handle will cause the outward swing handle to open and unlock.

Generally, when a side collision occurs, the door will be greatly deformed. When the car has a side collision, the collision will cause the door to be opened by mistake, and the occupant may be thrown out of the car, causing more serious secondary injuries, and the safety performance is low.
