A spring 135 is provided between the tray 133 and the second moving frame 131, the spring 135 is fitted around a pin (not shown), one end of the pin is fixed to one of the tray 133 and the second moving frame 131, and the length of the pin is shorter than the undeformed length of the spring 135 and longer than the shortest contracted length of the spring 135, so that the second moving frame 131 elastically supports the tray 133.

As shown in fig. 10-11, the side of the tray 133 is provided with a second prong 134, which second prong 134 is adapted to cradle the battery of the vehicle to be fixed relative to the battery of the vehicle. An insert 136 is provided below the tray 133, a V-shaped insertion groove 132 is provided above the second moving frame 131, and the tray 133 is fixed with respect to the second moving frame 131 by being inserted into the insertion groove 132 through the insert 136, so that the tray 133 can be driven to move when the second moving frame 131 moves laterally.

In the present embodiment, a structure of the battery lifting portion, which is a double-layer structure, is schematically shown.

The manner of movement of the first and second moving frames 121 and 131 with respect to the lifting frame 106 is briefly described below in connection with fig. 4 and 12.

As shown in fig. 4, the lifting frame 106 is laterally provided with a guide rail 150, and the lower surfaces of the first and second moving frames 121 and 131 are each provided with a guide block 140, and the guide blocks 140 slide on the guide rail 150. The first moving frame 121 and the second moving frame 131 share the same guide rail 150. The lifting frame 106 is further provided with a first driving part 160 and a second driving part 170, wherein the first driving part 160 is used for driving the first moving frame 121 to move transversely, and the second driving part 170 is used for driving the second moving frame 131 to move transversely.

As shown in fig. 12, the first moving frame 121 is disposed under the second moving frame 131, and the first moving frame 121 is connected to the first driving part 160 through the connection plate 124 to be driven by the first driving part 160. The first moving frame 121 is provided with a guide opening 125 to expose a guide block 140 coupled to the second moving frame 131. The second moving frame 131 is erected above the first moving frame 121 but is not in contact with the first moving frame 121, and a lower surface of the second moving frame 131 is connected with the second driving part 170 to be driven by the second driving part 170. The first and second driving parts 160 and 170 each include a screw nut transmission mechanism and a rotating motor driving a screw of the screw nut transmission mechanism to rotate, thereby achieving linear movement of the first and second moving frames 121 and 131. The screw nut transmission mechanism and the rotating motor are widely applied in the prior art, and are not described herein. Of course, other devices such as a linear motor may be used as the first and second driving parts 160 and 170 by those skilled in the art.

The first driving part 160, the second driving part 170 and the jacking driving unit 184 are all controlled by a control unit, which may be a control device provided to the shuttle type battery pack replacement apparatus 100 or a general control device of a battery exchange station to which the shuttle type battery pack replacement apparatus 100 is applied.

When it is necessary to disassemble the battery of the vehicle, the shuttle type battery pack changing apparatus 100 is first moved to the bottom of the vehicle. The first and second driving parts 160 and 170 receive the instruction and cause the first and second moving frames 121 and 131 to first move laterally to a predetermined position, then the lift driving unit 184 receives the instruction and causes the lift frame 106 to rise to a predetermined position, at which time the first fork 122 forks the lock base for locking the battery pack on the vehicle, the second fork 134 forks the battery of the vehicle, the unlocking mechanism 123 unlocks the battery lock so that the battery is no longer locked to the vehicle, then the first moving frame 121 remains stationary, and the second moving frame 131 moves in a direction away from the first moving frame 121 so that the battery is disengaged from the vehicle, the battery falls onto the tray 133 after being disengaged from the vehicle, then the lift frame 106 moves downward with the battery, and then the shuttle-type battery pack replacing apparatus 100 drives away from the bottom of the vehicle with the battery detached.

When it is desired to mount the battery of the vehicle, the shuttle-type battery pack changing apparatus 100 moves to the bottom of the vehicle with the battery fully charged, the first and second driving parts 160 and 170 receive the instruction and cause the first and second moving frames 121 and 131 to first laterally move to the predetermined position, the lift driving unit 184 receives the instruction and causes the lift frame 106 to rise to the predetermined position, at which time the first fork 122 forks the lock base for locking the battery pack on the vehicle, the second fork 134 forks the battery fully charged, and then the first moving frame 121 remains stationary while the second moving frame 131 moves in a direction approaching the first moving frame 121 so that the battery is fixed to the vehicle and the unlocking mechanism 123 locks the battery to the vehicle.

As shown in fig. 13, the power exchange station includes: a charging chamber (not shown), a battery exchange platform 190, an elevating mechanism 191, and a shuttle battery pack exchange apparatus 100.

The lifting mechanism 191 is disposed on the power exchanging platform 190 and is used for lifting and lowering the vehicle 200 on the power exchanging platform 190. Lifting mechanism 191 is typically a pier for supporting four wheels of vehicle 200. In fig. 13, the lifting mechanism 191 is in a lifted state.

The shuttle type battery pack changing apparatus 100 can be moved to and from the battery changing table 190 and the charging chamber for transporting the battery 210 fully charged in the charging chamber to the vehicle 200 or transporting the battery 210 detached from the vehicle 200 to the charging chamber for charging.

When the shuttle type battery pack changing apparatus 100 is loaded with the battery 210 (whether the battery is detached from the vehicle 200 or the battery is fully charged) and it is desired to get in and out from the bottom of the vehicle 200, the lifting mechanism 191 lifts the vehicle 200 upward to allow the shuttle type battery pack changing apparatus 100 to get in and out smoothly from the bottom of the vehicle 200.

Since the shuttle type battery pack replacement apparatus 100 employs the cam mechanism, which is itself low in height (apparatus overall height 175 mm), 4 cams 181 simultaneously lift 80mm, and the floor of the vehicle 200 is generally 190 mm in height from the ground. After the vehicle 200 enters the battery changing table 190, the shuttle type battery pack changing device 100 can directly enter the bottom of the vehicle 200, and the shuttle type battery pack changing device 100 lifts 80 and mm, so that locking or unlocking of the battery can be achieved. After the battery is removed, the lifting mechanism 191 lifts the vehicle 200 up to 200mm to allow the shuttle-type battery pack changing apparatus 100 to be removed from the bottom of the vehicle 200 with the battery.

Because the overall height of the shuttle battery pack replacement apparatus 100 is reduced, the battery pack replacement station 190 of the power exchange station does not need to be provided with deeper pits to allow the shuttle battery pack replacement apparatus 100 to enter the bottom of the vehicle 200, and therefore, the overall height of the battery pack replacement apparatus 190 is reduced, and the heights of the ascending ramp and the descending ramp entering the battery pack replacement apparatus 190 can be reduced to 230mm (the original height is 480 mm), and further, the difficulty in driving in the vehicle 200 is reduced. The lengths of the ascending ramp and the descending ramp are correspondingly reduced from the original 7345 mm and 4545 mm to 4500mm and 3000mm, so that the construction cost of the power exchange station is reduced.

While specific embodiments of the application have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and the scope of the application is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the principles and spirit of the application, but such changes and modifications fall within the scope of the application.
