[0043] Along the height direction of the back door, that is, the height direction of the vehicle, the back door interior panel 20 has a median line. Along the width direction of the back door, that is, the width direction of the vehicle, the back door interior panel 20 has two side edges arranged opposite to each other, both of which extend along the height direction of the back door, and the line connecting the midpoints of the two side edges is constructed as the median line of the back door interior panel 20. The unlocking drive mechanism 1 is located above the median line, so that the unlocking drive mechanism 1 can be arranged at a higher position of the back door, which is convenient for trapped passengers in the vehicle to quickly find the position of the unlocking drive mechanism 1, and it is convenient for trapped passengers to unlock the back door lock 10 by controlling the unlocking drive mechanism 1, which is conducive to the rapid escape of trapped passengers.

[0044] When the vehicle is severely deformed and the trapped passengers are stuck in a specific position inside the vehicle, since the unlocking drive mechanism 1 is arranged at a higher position on the tailgate, the rescuers can access the unlocking drive mechanism 1 by smashing the tailgate glass, which makes it easy for the rescuers to unlock the tailgate lock 10 by controlling the unlocking drive mechanism 1, thereby facilitating the rescuers to quickly carry out subsequent rescue.

[0045] Specifically, the back door is provided with a back door lock 10, and the back door lock 10 can be used to lock or unlock the back door. The unlocking wire 2 is connected between the unlocking drive mechanism 1 and the back door lock 10, and the unlocking drive mechanism 1 can drive the unlocking wire 2 to move so that the back door lock 10 is unlocked. The back door has a back door interior panel 20, and along the height direction of the back door, that is, the height direction of the vehicle, the back door interior panel 20 has a midline, and the unlocking drive mechanism 1 is located above the midline, so that the unlocking drive mechanism 1 can be arranged at a higher position of the back door, which is convenient for trapped passengers in the car to quickly find and control the unlocking drive mechanism 1 to unlock the back door lock 10. When the vehicle is severely deformed and the trapped passengers are stuck in a specific position in the car, the rescuers can control the unlocking drive mechanism 1 to unlock the back door lock 10 by smashing the back door glass, so that the rescuers can quickly carry out subsequent rescue.

[0046] Therefore, by setting the unlocking drive mechanism 1 to drive the unlocking wire 2 to unlock the tailgate lock 10, and the unlocking drive mechanism 1 is located above the midline, the unlocking drive mechanism 1 can be arranged at a higher position of the tailgate, which is convenient for trapped passengers in the vehicle to quickly find and open the tailgate lock 10, and rescuers can open the tailgate lock 10 by smashing the tailgate glass, which is conducive to the rapid rescue of rescuers, meets the passengers' needs for rapid escape, and thus improves the safety of vehicle use.

[0047] In some embodiments of the present invention, Figure 4 As shown, the distance between the unlocking drive mechanism 1 and the midline is greater than the distance between the unlocking drive mechanism 1 and the upper edge of the rear door interior trim panel 20 .

[0048] The unlocking drive mechanism 1 is arranged on the rear door interior panel 20. Along the height direction of the vehicle, the rear door interior panel 20 has a relative upper edge and a lower edge. The distance between the upper edge and the unlocking drive mechanism 1 and the unlocking drive mechanism 1 is less than the vertical distance between the unlocking drive mechanism 1 and the midline. This arrangement allows the unlocking drive mechanism 1 to be arranged at a higher position on the rear door, making it easier for trapped passengers in the vehicle to find the position of the unlocking drive mechanism 1 more quickly and unlock the rear door. It is further easier for rescuers to control the unlocking drive mechanism 1 to unlock the rear door lock 10 by smashing the rear door glass, thereby further meeting the passengers' needs for quick escape.

[0054] Among them, the rotating shaft 112 is rotatably arranged on the back door interior panel 20, so that the unlocking handle 11 can be rotated relative to the back door interior panel 20, so that the passenger can drive the unlocking pull wire 2 to unlock the back door lock 10 by rotating the unlocking handle 11. The rotating shaft 112 can be rotatably arranged on the back door interior panel 20 through a bearing, and the rotating shaft 112 can also be assembled in the pivot hole of the back door interior panel 20, so that the rotating shaft 112 can be rotatably arranged on the back door interior panel 20. The handle body 111 and the connecting block 113 are both fixedly arranged on the rotating shaft 112. As some embodiments of the present application, the handle body 111, the rotating shaft 112 and the connecting block 113 can be integrally formed to reduce the risk of cracking or even disconnection of the handle body 111, the rotating shaft 112 and the connecting block 113, which is conducive to improving the overall structural stability of the unlocking handle 11. As some embodiments of the present application, the handle body 111 and the connecting block 113 can be connected to the rotating shaft 112 by a convex key, so as to improve the reliability of the synchronous rotation of the handle body 111, the connecting block 113 and the rotating shaft 112, and reduce the risk of the handle body 111, the connecting block 113 and the rotating shaft 112 being detached, thereby reducing the risk of the rear door lock 10 being difficult to unlock due to the failure of the unlocking handle 11.

[0055] The connecting block 113 is connected to the unlocking cable 2, and the connecting block 113 and the unlocking cable 2 can be connected by, but not limited to, riveting, hooking, etc. Specifically, since the handle body 111 and the connecting block 113 are both fixed to the rotating shaft 112, the passenger can rotate the handle body 111, so that the rotating shaft 112 and the connecting block 113 rotate together with the handle body 111, and when the connecting block 113 rotates, it can drive the unlocking cable 2 to move so that the tailgate lock 10 is unlocked, thereby achieving the effect of unlocking the tailgate lock 10 by rotating the handle body 111.

[0056] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the unlocking handle 11 is movably disposed on the rear door interior panel 20 .

[0057] The unlocking handle 11 is movably disposed on the rear door interior panel 20, for example, the unlocking handle 11 can be translated along the surface of the rear door interior panel 20, and the unlocking handle 11 can also be pulled in a direction away from the rear door interior panel 20, but the present application is not limited thereto, and the unlocking handle 11 can also be movably disposed on the rear door interior panel 20 in other ways, as long as the unlocking handle 11 is movably disposed on the rear door interior panel 20. The present application takes the example of pulling the unlocking handle 11 in a direction away from the rear door interior panel 20 as an example, and the unlocking handle 11 is movably disposed on the rear door interior panel 20, and the pulling design facilitates the occupant to apply force, thereby reducing the difficulty for the occupant to drive the unlocking wire 2 through the unlocking drive mechanism 1 to unlock the rear door lock 10, thereby improving the opening efficiency of the rear door lock 10.

When the rear door needs to be opened, the passenger overcomes the elastic force to rotate the handle body 111, thereby controlling the unlocking handle 11 to drive the unlocking wire 2 to unlock the rear door lock 10. When the passenger releases the handle body 111, the elastic force of the torsion spring controls the handle body 111 to reset.

[0060] As some embodiments of the present application, when the unlocking handle 11 is movably disposed on the back door interior panel 20, the reset driving member 3 can be constructed as a spring, one end of the spring can be assembled on the handle body 111, and the other end of the spring can be assembled on the back door interior panel 20. When the back door needs to be opened, the passenger overcomes the tension of the spring and pulls the handle body 111, thereby controlling the unlocking handle 11 to drive the unlocking wire 2 to unlock the back door lock 10. When the passenger releases the handle body 111, the tension of the spring controls the handle body 111 to reset. After the handle body 111 is reset, the back door is closed, and the back door lock 10 can be automatically locked, thereby improving the closing efficiency of the back door.

[0061] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the tailgate interior panel 20 is formed with a mounting groove 201 recessed toward the inside of the tailgate, and at least a portion of the unlocking drive mechanism 1 is located in the mounting groove 201 .

[0062] The rear door interior panel 20 may be formed with a mounting groove 201 that is recessed toward the rear door, and the mounting groove 201 is open toward the interior of the vehicle.

[0068] When a vehicle with three rows of seats has a safety accident, it is necessary to ensure that the third row of passengers can evacuate the vehicle quickly. Due to the luxury and comfort requirements of the second row of seats, the seats usually have wide armrests, which results in limited space for the third row of passengers to get off the vehicle, and even the aisle between the second row of seats and the door is difficult for people to pass. The second row of seats needs to be moved forward a certain distance before the third row of passengers can get off the vehicle from the rear side of the seat. This application uses the back door as a quick escape channel for the third row of passengers, sets an unlocking drive mechanism 1 to drive the unlocking pull wire 2 to unlock the back door lock 10, and cooperates with the third row of seat backs that can be quickly folded, so that the escape channel for passengers to escape through the back door is unobstructed. The structure is simple and reliable, and the evacuation and rescue speed of trapped passengers in three-row vehicles is effectively improved, thereby meeting the passengers' needs for quick escape and improving the safety of vehicle use.
