When the supporting plate 18 moves to the charging single cabinet 3 with the electric quantity indicator 4 lighted, the control system 24 orders the air cylinder 232 to start, the air cylinder 232 pushes the charged battery to the supporting plate 18 through the push plate 231, meanwhile, the control system 24 orders the first power part to start, the first power part orders the battery to move towards the direction close to the calibration plate through the belt line, and therefore the battery is stably stored on the supporting plate 18. The support plate 18 outputs the charged batteries from the feeding hole 17, so that the workers can conveniently and quickly take the batteries for replacement.

In the second embodiment of the present application, an implementation principle of a battery rack for a quick replacement system of an electric bicycle battery pack is as follows: when the base 1 is detached from the battery replacing operation vehicle 10, the control system 24 drives the cabinet 2 to rotate the battery to the side plate 13 with the feeding hole 17 through the rotating motor 34. Then, the control system 24 drives the lifting assembly 16 to start, when the lifting assembly 16 drives the supporting plate 18 to move to the charging single cabinet 3 with the electric quantity indicator 4 lighted, the control system 24 drives the discharging assembly 23 and the pushing assembly 21 to start, and the charged battery is stably supported on the supporting plate 18 under the combined action of the discharging assembly 23 and the pushing assembly 21. Then the control system 24 drives the lifting assembly 16 to move, the lifting assembly 16 drives the supporting plate 18 to move towards the direction close to the second driving member, when the supporting plate 18 moves to the feeding hole 17, the second driving member drives the supporting plate 18 to move towards the direction away from the cabinet body 2, so that the supporting plate 18 transmits the charged batteries to the side of the side plate 13 away from the cabinet body 2, and at the moment, a worker can take off the charged batteries for replacement.

The staff will change the dead battery and place in backup pad 18, and control system 24 orders about backup pad 18 to move towards the direction of keeping away from base 1, and first driving piece 19 orders about backup pad 18 to drive dead battery and moves to the side that curb plate 13 is close to cabinet body 2, and control system 24 orders about calibration subassembly 22 to start simultaneously, and calibration subassembly 22 calibrates the position of battery. When the control system 24 drives the supporting plate 18 to move to the empty charging single cabinet 3, the control system 24 drives the battery without electricity to be automatically inserted into the charging single cabinet 3 through the pushing assembly 21 and the calibration assembly 22, and then the automatic taking and placing of the battery can be completed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
