When the push plate 8 tends from the initial state to the first motion state, the second drive shaft 17 moves from the first section to the second section, and the push plate 8 drives the rotating member 12 to rotate through the second drive shaft 17, thereby driving the door lock 4 to open through the pull wire 11, and the transmission method is reliable and stable, and the structure is simple. In the embodiment of the present invention, the pull wire 11 is a brake wire, the first section and the second section of the second drive groove 18 are connected at an obtuse angle, and the second section is parallel to the guide groove 22, and the first section extends toward the inner side of the push plate 8 relative to the second section. When the push plate 8 is in the initial state, the second drive shaft 17 is located in the first section, and when the push plate 8 tends from the initial state to the first motion state, the second drive shaft 17 reaches the second section, and in the second motion state and the third motion state, the second drive shaft 17 is located in the second section.

[0041] Preferably, the first rotating shaft 24 of the rotating member 12 is arranged close to the second driving shaft 17, so that the rotating member 12 will form a lever, and only a small movement stroke of the second driving shaft 17 is needed to drive the corresponding end of the rotating member 12 to rotate with a small stroke, while the other end produces a larger stroke rotation, thereby easily pulling the pull wire 11 to drive the door lock 4 to open.

6. A linkage device according to claim 1, characterized in that: The battery lock (9) is rotatably mounted on the mounting frame (14) via a second rotating shaft (25); the battery lock (9) is provided with a third driving shaft (19); the push plate (8) is provided with a third driving groove (20); the third driving shaft (19) is movably plugged into the third driving groove (20); the third driving groove (20) has a first section and a second section connected, and the width of the first section is greater than the width of the second section; when the push plate (8) moves from a first motion state to a second motion state, the third driving shaft (19) moves from the first section to the second section, and the push plate (8) drives the battery lock (9) to rotate via the third driving shaft (19), thereby enabling the battery lock (9) to be opened.

7. A linkage device according to claim 6, characterized in that: The first end of the battery lock (9) is a lock hook, which can be matched with the lock slot of the battery. The second end of the battery lock (9) is provided with the third drive shaft (19), and the second end is also connected to a second elastic member (13). The second elastic member (13) is configured to make the battery lock (9) always have a tendency to make the lock hook match with the lock slot of the battery.

8. A linkage device according to claim 7, characterized in that: The battery lock (9) is connected to an emergency part (26), an end of which extends out of the linkage device (5), and the battery lock (9) can be driven to rotate by operating the emergency part (26).
