[0094] The first main driving rod 221 and the second main driving rod 222 of the present invention form a two-link mechanism 22; in the present invention, the two-link mechanism 22 drives the vehicle door 1 to open or close by receiving power output from the driver.

[0095] The locking groove 2311 is divided into two sections, namely, a guiding straight section 23111 and a transition section 23112; the guiding straight section 23111 is the L1 section, and the transition section 23112 is the L2 section.

[0096] The function of the L1 segment is to guide the rear door 11 into the trajectory during the rotation of the two link mechanisms 22 by a defined angle. Figure 4 , ensuring that the rear door 11 maintains a defined safety distance from the front door 12 during the process of continuing to open, and the length of the safety distance depends on the size required to guide the rear door 11 into the trajectory.

[0097] The function of the L2 section is to reliably guide the rear door 11 into the L1 section during its closing process.

[0098] The first telescopic rod 24 maintains the posture of the vehicle door 1 during the opening or closing process by changing its length, ensuring that the vehicle door 1 is parallel to the vehicle body when fully opened.

[0099] The auxiliary support system 3 opens / contracts as the door 1 opens / closes, thereby keeping the movement of the door 1 stable and reliable.

[0100] The first mounting bracket 21 is fixed to a vehicle body frame (not shown).

[0101] The number one rod is the first main driving rod 221 .

[0103] The first rod and the second rod are connected by a pin shaft and can rotate relative to each other; the second rod is the second main driving rod 222.

[0104] The second rod is fixed on the vehicle door 1. The second rod has a protruding structure for fixing the lock catch 232.

[0105] The first rod and the second rod each have a protruding structure for connecting the second telescopic rod 33 .

[0106] The lock body 231 is fixed on the vehicle body frame.

[0107] The second mounting bracket 31 is fixed to a vehicle body frame (not shown).

[0108] The third rod is the first secondary connecting rod 321 , the fourth rod is the second secondary connecting rod 322 , and the fifth rod is the third secondary connecting rod 323 .

[0111] The fifth rod is fixed on the vehicle door 1.

[0112] The third rod and the fifth rod each have a protruding structure for connecting the second telescopic rod 33 .

[0113] In the first stage of the movement, that is, the L1 section working area of ​​the locking groove 2311.

[0114] The driver drives the two connecting rod mechanisms 22 to rotate through a defined angle, which makes the moving length of the system in the locking slot 2311 be L1.

[0115] The two link mechanisms 22 drive the rear door 11 to enter through a rigid connection. Figure 4 Within the trajectory shown, it is ensured that the rear door 11 maintains a defined safety distance from the front door 12 during the subsequent movement.

[0116] In the first stage of the movement, the first telescopic rod 24 can be actively extended and retracted to provide power.

[0117] It can also passively expand and contract to play a damping role and keep the system running smoothly.

[0118] In the first stage of the movement, the auxiliary support system 3 moves with the vehicle door 1 through a rigid connection, so as to keep the system running stably and reliably.

[0119] In the second stage of the movement, that is, the L1 section of the locking groove 2311 is completed.

[0120] The driver drives the two-link mechanism 22 to continue to rotate through a defined angle, which depends on the definition of the opening of the door 1 and the definition of the safe distance between the fully opened door 1 and the vehicle body.

[0121] In the second stage of the movement, the first telescopic rod 24 actively retracts and contracts to maintain the posture of the door 1 during the opening or closing process, ensuring that the door 1 is parallel to the vehicle body when fully opened.

[0122] The telescopic length is defined according to factors such as the opening degree of the door 1 and whether the door 1 is parallel to the vehicle body when fully opened.

[0123] In the second stage of the movement, the auxiliary support system 3 moves with the vehicle door 1 through a rigid connection, so as to keep the system running stably and reliably.
