As shown in fig. 6 and 7, the distance detecting device 212 is provided with a spring piece 211, when the emergency protective cover 26 is not rotated, the spring piece 211 is tightly attached to the back surface of the emergency protective cover 26, once the emergency protective cover 26 is rotated, the spring piece 211 is compressed, the distance between the spring piece 211 and the distance detecting device 212 is adaptively changed, when the distance detecting device 212 detects a preset alarm distance relative to the distance between the spring piece 211, an alarm signal is generated, and then the alarm signal is transmitted to the domain controller through the communication line 213 to alarm, such as making a sound and/or a picture to alarm, so that a user can be reminded that the emergency protective cover 26 is triggered, and the effect of prompting the user to stop in time can be played when the child or the old uses the vehicle door emergency device by mistake, so that the user is avoided using the vehicle door emergency device by mistake.

As shown in fig. 6 and 7, in some embodiments, the internal emergency unlocking mechanism 2 includes:

A door opening part 22 connected to the inner flexible cable 23, and pulling the inner flexible cable 23 after being triggered;

An internal flexible inhaul cable 23, one end of which is connected with the vehicle door opening part 22, and the other end of which is connected with the emergency connecting rod 5, and can drive the emergency connecting rod 5 to rotate after being pulled;

A component support bracket 24 connected to the door opening member 22 for supporting the door opening member 22.

As shown in fig. 7, the door is easily opened by operating the door opening member 22 such as sliding the door, thereby driving the inner flexible cable 23 and pulling the door lock under the tension of the inner flexible cable 23.

As shown in fig. 7, in some embodiments, the door opening member 22 includes a spring (not shown) and a slider 221, the slider 221 connecting the inner flexible cable 23 with the spring,

The spring is secured to the component support frame 24,

The sliding block 221 compresses the spring when sliding on the sliding rail of the component support frame 24, specifically, the sliding block 221 pulls the inner flexible cable 23 and compresses the spring when sliding, so that the user can reset by using the spring when releasing the sliding block 221.

As shown in fig. 6 and 7, the door opening member 22 may be composed of a spring (of course, the spring is not shown in fig. 6 and 7 for simplicity of the drawing) and a slide block 221, the spring being located directly under the slide block 221, of course, the spring being compressed when the slide block 221 slides on a slide rail, the inner flexible cable 23 being pulled downward, thereby opening the door lock by the other end of the inner flexible cable 23 to easily open the door in an emergency.

In addition, after the door is opened, the user releases the sliding block 221, and the sliding block 221 can be quickly reset under the action of spring force without manual reset, so that the operation convenience of the internal emergency unlocking mechanism 2 can be further improved.

What has been described above is merely illustrative of the principles and preferred embodiments of the present application. It should be noted that several other variants are possible to those skilled in the art on the basis of the principle of the application and should also be considered as the scope of protection of the present application.
