[0029] When the cover plate 2 is in the closed position on the fixed seat 1, the locking block 3 on the cover plate 2 is inserted into the cavity 4 on the fixed seat 1, and one end of the locking member 5 is inserted on the locking block 3, providing fixation for the cover plate 2 in the closed position on the fixed seat 1; when the small vehicle door is powered off in an emergency, the cover plate 2 can be unlocked by manually pulling the operating member 8, and the specific process is as follows: manually pull the operating member 8, the unlocking member 7 is driven by the operating member 8, the unlocking member 7 abuts against the locking member 5, and drives the locking member 5 to separate from the locking block 3, the locking block 3 moves out of the cavity 4 on the fixed seat 1, after the locking block 3 leaves the cavity 4, the cover plate 2 can rotate from the closed position to the maximum unfolded position on the fixed seat 1, during this process, only need to manually pull the operating member 8 to open the small vehicle door, which is not affected by the power-off of the small vehicle door, thus ensuring the use experience and the maintenance convenience of the vehicle.

[0030] For the locking member 5 to be inserted into the locking block 3, a through hole 9 is provided on the locking block 3. The locking member 5 and the unlocking member 7 are arranged opposite to each other, on both sides of the through hole 9. One end of the locking member 5 is movably inserted into the through hole 9, thereby providing a fixing effect when the cover plate 2 is in the closed position on the fixed seat 1, ensuring that the cover plate 2 will not be accidentally opened in the closed state.

[0031] Specifically, the unlocking assembly 6 further includes: a mounting seat 10, which is connected to one end of the cavity 4; an elastic member 11. An installation groove is provided in the mounting seat 10. One end of the elastic member 11 is inserted into the installation groove, and the other end abuts against one side of the unlocking member 7. The elastic member 11 is preferably a spring.

[0032] Furthermore, a pushing column 12 is provided on the unlocking member 7. One end of the pushing column 12 is movably inserted into the through hole 9 on the locking block 3 and abuts against the locking member 5 movably. The pushing column 12 is used to drive the locking member 5 away from the through hole 9.

[0033] Furthermore, a surrounding inclined surface 13 is provided at one end of the pushing column 12 that is movably inserted into the through hole 9. The locking block 3 can slide along the inclined surface 13 and pass over the pushing column 12 due to the unlocking member 7 moving away from the through hole 9, and finally leave the cavity 4.

[0034] Manually pull the operating member 8. The operating member 8 drives the unlocking member 7 to move, thereby driving the pushing column 12 to abut against the locking member 5 and pushing the locking member 5 away from the through hole 9. At this time, the elastic member 11 is compressed and undergoes elastic deformation. Stop manually pulling the operating member 8, and the elastic member 11 recovers elastic deformation, driving the unlocking member 7 back to its original position. At the same time, the locking block 3 is driven by the cover plate 2 to move along the inclined surface 13 and finally pass over the pushing column 12, disengaging from the cavity 4. Subsequently, the cover plate 2 rotates from the closed position to the maximum unfolded position on the fixed seat 1.

[0035] Furthermore, a driving member 14 is also provided on the fixed seat 1. One end of the locking member 5 away from the cavity 4 is arranged at the output end of the driving member 14. The driving member 14 is used to drive the locking member 5 to move. When the cover plate 2 rotates from the maximum unfolded position to the closed position on the fixed seat 1, it drives the locking block 3 to be inserted into the cavity 4. The locking member 5 is driven by the driving member 14 to be inserted into the through hole 9. At this time, the unlocking member 7 is located at the relative position of the locking member 5. Due to the arrangement of the elastic member 11, when the locking member 5 is inserted into the through hole 9 and abuts against the unlocking member 7, the unlocking member 7 will be pushed by the locking member 5, so as not to interfere with the operation of the locking member 5. When the vehicle door is not powered off, the driving member 14 can be used to drive the locking member 5 away from the through hole 9, so that the locking block 3 leaves the cavity 4. The driving member 14 can be a motor or an electromagnet.

[0036] In order to connect the operating member 8 and the unlocking member 7, a hollow portion 15 is provided on the mounting seat 10. One end of the operating member 8 is connected to one end of the unlocking member 7 through the hollow portion 15.

[0037] Specifically, the operating member 8 is a wire rope. One end of the wire rope is connected to the unlocking member 7, and the other end extends into the carriage and is hidden by a fixing clip or a hook inside the carriage, so as to ensure the stability of the wire rope inside the carriage, keep the appearance of the carriage clean and safe, and also facilitate manually pulling the wire rope to unlock the cover plate 2 in case of an emergency.
