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.

Embodiment 1

[0027] Such as figure 1 As shown, the automobile includes a car door 1, and a car lock 2 is arranged in the car door 1. The car lock 2 includes an inner locking twist 21 and a lock body 22. The contact part 32 at the outer end and the connecting part 33 in the middle, the hinge part 31 and the connecting part 33 have a smooth transition, the contact part 32 and the connecting part 33 have a smooth transition, the hinge part 31 is hinged with the lock body 22, and the deformation sensing rod 3 can go around the hinge point Rotation, in the present embodiment, there is a gap between the connection of the hinged part 31 and the connecting part 33 and the outside of the inner locking knob 21, and the distance of the gap is 1 mm. In actual production, the distance of the gap can be 5 mm or 10 mm, the joint between the hinged part 31 and the connecting part 33 may also directly abut against the outer side of the inner locking knob 21 . In this embodiment, there is a gap between the...

Embodiment 2

[0030] Such as image 3 As shown, the structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the deformation sensing rod 3 includes the abutting portion 34 at the inner end, the rotating portion 35 in the middle and the touching portion at the outer end 36, the rotating part 35 and the touch part 36 transition smoothly, the abutting part 34 and the rotating part 35 are approximately perpendicular, the rotating part 35 is hinged with the lock body 22, the deformation sensing rod 3 can rotate around the hinge point, the abutting part 34 and the inner There is a gap between the inner sides of the locking knobs 21, and the distance of the gap is 1mm. In actual production, the distance of the gap can be 5mm or 10mm, and the abutting portion 34 can also abut against the inner side of the inner locking knobs 21, The axial centerline of the touch portion 36 is substantially perpendicular to the outer panel ...

Embodiment 3

[0032] Such as Figure 4 As shown, the structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the deformation sensing rod 3 is in the shape of a straight rod, and the inner end of the deformation sensing rod 3 is connected to the inner locking torque 21. There is a gap between the outer sides, and the distance of the gap is 1 mm. In actual production, the distance of the gap can be 5 mm or 10 mm. The inner end of the deformation sensing rod 3 can also directly abut against the outer side of the inner locking torque 21, deforming The sensing rod 3 can move along the axial direction of the deformation sensing rod 3 .

Abstract

The invention provides a safety device for preventing a car door from being opened in the lateral colliding process, and belongs to the technical field of automobile parts. The problems that when lateral collisions happen to an existing car, a car door is opened by mistake, and a passenger can be hurt twice are solved. According to the safety device for preventing the car door from being opened in the lateral colliding process, a car comprises the car door, a car lock is arranged in the car door, and comprises an inner locking button, the safety device comprises a deformation induction rod in the car door, the inner end of the deformation induction rod is in linkage with the inner locking button, the outer end of the deformation induction rod abuts against an outer plate of the car door, or a clearance exists between the outer end of the deformation induction rod and the outer plate of the car door. When the outer plate of the car door moves inwards, the outer plate of the car door pushes the deformation induction rod, and the deformation induction rod is made to drive the inner locking button to lock the car door. The safety device for preventing the car door from being opened in the lateral colliding process has the advantages of being high in transmission sensitivity and good in 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...
