In some embodiments of the present invention, the battery replacing robot 3 may be an AGV cart. The stacker crane 4 is used for transferring the battery 8 between the battery replacing robot 3 and the battery rack 5.

Specifically, after the electric automobile stops at parking area 1, trade electric robot 3 can remove the vehicle bottom to electric automobile to take off the insufficient voltage battery on the electric automobile, trade electric robot 3 and carry the insufficient voltage battery who takes off and remove to battery frame 5 after that, hacking machine 4 can shift the insufficient voltage battery to battery frame 5 this moment, and shift full-charge battery on the battery frame 5 to trade electric robot 3 on, trade electric robot 3 and carry full-charge battery to remove to electric automobile's vehicle bottom after that, and install full-charge battery on electric automobile, accomplish the change of battery 8. The structure of the palletizer 4 is well known to those skilled in the art and will not be described in detail herein.

According to the utility model discloses trade power station 100 through setting up parking area 1 outside container 2 to the electricity changing robot 3 that the setting can freely remove between parking area 1 and battery rack 5 has cancelled the electricity changing platform among the correlation technique, has greatly simplified the structure of trading power station 100, has reduced the volume of container 2 (for example, in some embodiments of the utility model, container 2 can be for 3 meters in the bottom surface size), and the installation and the transportation of container 2 of being convenient for have reduced installation and cost of transportation.

According to some embodiments of the present invention, the battery rack 5 comprises a buffer rack 51 and a charging rack 52, and the buffer rack 51 and the charging rack 52 are respectively disposed at two sides of the stacker crane 4.

As shown in fig. 2 and 3, the buffer frame 51 may be disposed on a side of the palletizer 4 close to the open mouth 21 of the container 2, and the charging frame 52 may be disposed on a side of the palletizer away from the open mouth 21 of the container 2. Specifically, the buffer rack 51 is used for temporarily storing the insufficient-power battery removed from the electric vehicle. In the battery replacing process, after the battery replacing robot 3 moves to the battery rack 5, the insufficient battery can be stored on the buffer rack 51, after the full-charge battery is placed on the battery replacing robot 3 by the stacker crane 4, the insufficient battery on the buffer rack 51 is transferred to the charging rack 52 by the stacker crane 4, and the insufficient battery is charged. Therefore, the battery replacement method can avoid the confusion of the insufficient battery and the full battery, and is favorable for improving the battery replacement efficiency.

The gripping member 63 may be used to grip the battery 8.

For example, before the swapping robot 3 moves to the buffer rack 51, the first driving mechanism 61 may drive the grabbing piece 63 to descend, the second driving mechanism 62 may drive the grabbing piece 63 to rotate so that the grabbing piece 63 avoids the swapping robot 3, so as to avoid interference between the grabbing piece 63 and the swapping robot 3, and when the swapping robot 3 moves to the buffer rack 51, the second driving mechanism 62 drives the grabbing piece 63 to rotate so that the grabbing piece 63 extends into the bottom of the insufficient battery, so as to take the insufficient battery out of the swapping robot 3. Meanwhile, the stacker crane 4 can take the fully charged battery off the charging rack 52 and place the fully charged battery on the charging robot 3. The gripper 63 can then be driven by the first drive mechanism 61 to move into abutment with the stacker 4, and the brown-out battery is transferred by the stacker 4 onto the charging rack 52. From this, can improve battery 8's transportation efficiency, and then can improve and trade electric efficiency, it is long when sparingly trading the electricity.

According to the utility model discloses a some embodiments are equipped with a plurality of places 53 on charging frame 52, and a plurality of places 53 are at the interval setting in the direction of height of charging frame 52. In the description of the present invention, "a plurality" means two or more. Thereby, the storage capacity of the charging stand 52 is improved, and the volume of the charging stand 52 and thus the volume of the container 2 can be reduced.

According to some embodiments of the present invention, referring to fig. 1, 2 and 4, the battery replacement robot 3 includes: a body 31, a traveling mechanism, and a battery mounting and dismounting mechanism 32. The traveling mechanism is arranged below the body 31 and is configured to drive the battery replacing robot 3 to reach a target position. The target positions may include positions below the battery 8 of the electric vehicle, below the buffer rack 51, and below the stacker crane 4. The battery detaching mechanism 32 is provided on the body 31, and the battery detaching mechanism 32 is used for detaching the battery 8 of the electric vehicle.

For example, the traveling mechanism may drive the battery replacement robot 3 to reach below the battery 8, below the buffer rack 51, and below the stacker 4 of the electric vehicle according to a preset traveling route. Therefore, the utility model discloses a trade electric robot 3 can be need not to lay special guide rail and need not to move between parking area 1 and battery holder 5 under the situation that sets up vehicle positioning mechanism on trading the electric platform, greatly increased trade electric robot 3's flexibility, reduced the complexity that trades station 100.

According to some embodiments of the present invention, the battery replacement robot 3 further includes a positioning sensor 33 and a controller. The positioning sensor 33 can at least acquire the relative position of the current position and the target position of the battery replacing robot 3. The controller is communicated with the positioning sensor 33 and the travelling mechanism, and the controller is configured to control the travelling mechanism to work according to the relative position acquired by the positioning sensor 33 so that the electric replacing robot 3 reaches the target position.

Specifically, under the control of the controller, the traveling mechanism and the positioning sensor 33 can form a control closed loop, the control closed loop enables the positioning sensor 33 to acquire the relative position between the current position of the battery replacing robot 3 and the target battery replacing position every time the battery replacing robot 3 adjusts the position once through the rolling of the traveling mechanism, and the controller controls the traveling mechanism to roll through the relative position to further adjust the position of the battery replacing robot 3 until the battery replacing robot 3 reaches the target position.

It can be seen that the battery replacement robot 3 is moved by the traveling mechanism, and the traveling mechanism, the controller and the positioning sensor 33 form a control closed loop, so that the battery replacement robot 3 can move to a target position under the condition of being separated from the guide rail, and the battery 8 replacement action and the battery 8 transportation action of the electric vehicle to be replaced are realized. From this, not only improved the motion flexibility of trading electric robot 3 for trade electric robot 3 can break away from traditional guide rail and remove, has removed the degree of difficulty of laying of guide rail from, has still simplified the structure of trading power station 100 greatly, makes electric automobile need not accurate positioning on parking area 1, even need not under the situation of location, can change power battery 8.
