Vehicle door auxiliary locking device and vehicle provided with same

JANG YOU-JIN / LU ZHEN / SHI WEN

The vehicle door auxiliary locking device can improve the impact resistance of a vehicle door, is high in reliability, simple in structure and convenient to disassemble and assemble, and comprises a handle assembly (1), a linkage mechanism (2), a limiting mechanism (3) and a spring bolt, and the handle assembly (1) and the linkage mechanism (2) are connected in a manner that the handle assembly (1) and the linkage mechanism (2) cannot rotate relatively; the linkage mechanism (2) is fixedly connected with the limiting mechanism (3) and the spring bolt, the handle assembly (1) rotates to drive the linkage mechanism (2) to move, the linkage mechanism (2) moves to drive the limiting mechanism (3) and the spring bolt to move, and when the spring bolt is located at the locking position, the limiting mechanism (3) and the spring bolt are locked. When the spring bolt is located at the locking position, the limiting mechanism (3) is located at the first limiting position so as to keep the locking state of the auxiliary locking device for the vehicle door, and when the spring bolt is located at the unlocking position, the limiting mechanism (3) is located at the second limiting position so as to keep the unlocking state of the auxiliary locking device for the vehicle door.
