A spring 135 is provided between the tray 133 and the second moving frame 131, and the spring 135 is fitted over a pin (not shown) having one end fixed to one of the tray 133 and the second moving frame 131, and having a length shorter than an undeformed length of the spring 135 and longer than a 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, the second prong 134 for forking the battery of the vehicle to be fixed relative to the battery of the vehicle. An insertion member 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 inserting the insertion member 136 into the insertion groove 132, so that the tray 133 is moved when the second moving frame 131 moves laterally.

The movement of the first and second moving

frames

121 and 131 with respect to the lifting frame 106 will be briefly described below with reference to fig. 4 and 12.

As shown in fig. 4, the lifting frame 106 is laterally arranged with a guide rail 150, and the lower surfaces of the first moving frame 121 and the second moving frame 131 are each provided with a guide block 140, and the guide block 140 slides 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, 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 provided below 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 connected to the second moving frame 131. The second moving frame 131 is erected above the first moving frame 121 without contacting 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. Each of the first and second driving

parts

160 and 170 includes a screw nut transmission mechanism and a rotary motor that drives a screw of the screw nut transmission mechanism to rotate, thereby achieving linear motion of the first and second moving

frames

121 and 131. The lead screw nut transmission mechanism and the rotating motor have been widely used in the prior art, and are not described in detail herein. Of course, those skilled in the art may also adopt other devices such as a linear motor, etc. as the first and second driving

parts

160 and 170.

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

When it is necessary to remove the battery of the vehicle, the shuttle-type battery pack replacement apparatus 100 is first moved to the bottom of the vehicle. The first and second driving

parts

160 and 170 receive a command and make the first and second moving

frames

121 and 131 move laterally to a predetermined position first, then the jacking driving unit 184 receives a command and makes the lifting frame 106 ascend to a predetermined position, at which time the first fork 122 forks a lock base for locking a battery pack on the vehicle, the second fork 134 forks a battery of the vehicle, the unlocking mechanism 123 unlocks the battery lock so that the battery is no longer locked on 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 detached from the vehicle, falls onto the tray 133 after the battery is detached from the vehicle, then the lifting frame 106 moves downward, moves downward with the battery, and then the shuttle-type battery pack exchanging apparatus 100 moves away from the bottom of the vehicle with the detached battery.

When it is necessary to install the battery of the vehicle, the shuttle-type battery pack replacing apparatus 100 moves to the bottom of the vehicle with the fully charged battery, the first driving part 160 and the second driving part 170 receive a command and make the first moving frame 121 and the second moving frame 131 move laterally to a predetermined position first, the jacking driving unit 184 receives a command and makes the lifting frame 106 ascend to a predetermined position, at this time, the first fork 122 forks a lock base for locking the battery pack on the vehicle, the second fork 134 forks the fully charged battery, and then, the first moving frame 121 remains stationary while the second moving frame 131 moves toward a direction close to 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 swapping station includes: a charging room (not shown), a battery changing platform 190, a lifting mechanism 191, and a shuttle-type battery pack replacement apparatus 100.

The lifting mechanism 191 is arranged on the battery replacing platform 190 and used for lifting the vehicle 200 on the battery replacing platform 190. The lift mechanism 191 is typically a pier for supporting the four wheels of the vehicle 200. In fig. 13, the lifting mechanism 191 is in a lifted state.

The shuttle-type battery pack replacement apparatus 100 can shuttle between the swapping station 190 and the charging room for transporting the fully charged battery 210 in the charging room to the vehicle 200 or transporting the battery 210 detached from the vehicle 200 to the charging room for charging.

When the shuttle-type battery pack replacing apparatus 100 is loaded with the battery 210 (whether a battery detached from the vehicle 200 or a fully charged battery) and needs to enter and exit from the bottom of the vehicle 200, the elevating mechanism 191 lifts the vehicle 200 upward to allow the shuttle-type battery pack replacing apparatus 100 to smoothly enter and exit from the bottom of the vehicle 200.

Since the shuttle battery pack replacing apparatus 100 employs the cam mechanism, its height is low (the total height of the apparatus is 175mm), 4 cams 181 are lifted 80mm synchronously, and the height of the floor of the vehicle 200 from the ground is generally 190 mm. After the vehicle 200 enters the battery replacing platform 190, the shuttle-type battery pack replacing device 100 can directly enter the bottom of the vehicle 200, and the shuttle-type battery pack replacing device 100 is lifted by 80mm, so that the locking or unlocking of the battery can be realized. After the battery is removed, the lifting mechanism 191 lifts the vehicle 200 by 200mm to allow the shuttle-type battery pack exchanging apparatus 100 to be removed from the bottom of the vehicle 200 with the battery.

Because the overall height of the shuttle-type battery pack replacing device 100 is reduced, the battery replacing platform 190 of the battery replacing station does not need to be provided with a deeper pit to allow the shuttle-type battery pack replacing device 100 to enter the bottom of the vehicle 200, and therefore the overall height of the battery replacing platform 190 is reduced, so that the heights of an upper ramp and a lower ramp entering the battery replacing platform 190 can be reduced to 230mm (the original height is 480mm), and further, the difficulty in driving the vehicle 200 is reduced. The lengths of the up-ramp and the down-ramp are correspondingly reduced from 7345mm and 4545mm to 4500mm and 3000mm, so that the construction cost of the power station is reduced.

While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention 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 spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
