Description

TECHNICAL FIELD

[0001] The utility model relates to a battery replacement technical field, concretely relates to a battery replacement station's relay battery replacement equipment and including the equipment of battery replacement station. BACKGROUND

[0002] The working principle of the corresponding mobile device for battery replacement in the existing vehicle battery replacement process is generally as follows: the battery replacement device needs to be first moved to a battery replacement station to take down the battery box of the vehicle at the station, then moved to a battery taking station where the battery rack is located to store the battery box of the vehicle at the empty battery compartment of the battery rack, then get the full battery box from the battery rack, and finally moved to the battery replacement station to release the full battery box to the vehicle. In the whole battery replacement process, each mobile device performs the action of taking and placing the battery box for the same work object (vehicle) in series, and the total of all series actions lengthens the waiting time of the vehicle to be replaced, thereby increasing the occupancy of the single object in the battery replacement station and reducing the overall efficiency of the battery replacement station, and the disadvantage is more prominent when the vehicle is continuously replaced. SUMMARY

[0003] In view of the above existing problems, it is necessary to provide a battery replacement method and a battery replacement device to improve the battery replacement efficiency of the battery replacement station for vehicles and reduce the station rate of the vehicle. Therefore, the utility model provides a relay battery replacement device of a battery replacement station and a battery replacement station including the device. The relay battery replacement device provided by the utility model completes the transfer and replacement of the battery box of an object at one time through one transportation, avoids the action of replacing the battery box from another place after getting the battery box of the vehicle in the existing battery replacement process, and returns to the battery replacement station, thereby reducing the travel distance in the battery replacement process and improving the battery replacement efficiency of the vehicle.

[0004] Specifically, the utility model provides a relay battery replacement device of a battery replacement station, which comprises at least one running slide rail and at least two bridge type hoisting assemblies. The bridge type hoisting assembly comprises a bridge type hoisting frame and a hoisting overhead traveling crane arranged on the bridge type hoisting frame. The running slide rail is arranged between the battery taking station and / or the charging station and the battery replacement station. The at least two bridge type hoisting frames move along the running slide rail and independently bear the function of carrying the replacement battery box and / or the battery box of the vehicle to be replaced between the battery taking station and the battery replacement station and / or between the charging station and the battery replacement station. The hoisting overhead traveling crane moves along the bridge type hoisting frame and gets and / or releases the battery box of the vehicle to be replaced and / or the replacement battery box at the required position.

[0005] Preferably, each battery replacement station is provided with two bridge type hoisting assemblies, which generally bear the work of carrying the battery box of the vehicle to be replaced and the replacement battery box of one battery replacement station respectively (at the same time), so that the unloading of the battery box of the vehicle to be replaced and the loading of the replacement battery box are realized after one-time operation to the position (such as the battery replacement station).

[0006] Further, for the battery replacement demand of each battery replacement station, the first hoisting crane in the bridge hoisting assembly (cooperating through the connecting device, lifting device, etc.) carrying the replacement battery box from the battery taking station reaches the battery replacement station, the second hoisting crane moves above the depleted battery box to grab and carry the depleted battery box away, and then the first hoisting crane moves to the battery replacement station to release the replacement battery box, and the second hoisting crane moves to the charging station to release the depleted battery box.

[0007] Further, for the battery replacement demand of each battery replacement station, the first hoisting crane in the bridge hoisting assembly (cooperating through the connecting device, lifting device, etc.) carrying the replacement battery box from the battery taking station reaches the battery replacement station, the second hoisting crane moves above the depleted battery box to grab and carry the depleted battery box away, and then the first hoisting crane moves to the battery replacement station to release the replacement battery box, and the second hoisting crane moves to the charging station to release the depleted battery box.

[0008] For example, when there are N simultaneous battery replacement demands, N+1 bridge hoisting assemblies can be used to run at the same time, first taking N replacement battery boxes from the battery taking station, and then the first hoisting crane in the bridge hoisting assembly grabs and carries the depleted battery box of the first battery replacement station away, and then the adjacent bridge hoisting assembly releases the replacement battery box at the station to become the empty bridge hoisting assembly of the next battery replacement station, and so on to realize relay replacement of one-time taking.

[0009] Of course, for N simultaneous battery replacement demands, at most 2N (i.e., N+1 to 2N) bridge hoisting assemblies can be used to run at the same time, and such a setting is more complex but has higher efficiency.

[0010] Further, the relay battery replacement device can include two running rails respectively arranged between the battery taking station and the battery replacement station and between the battery replacement station and the charging station; and the two bridge hoisting assemblies of each battery replacement station are respectively located on the two running rails and independently run without interfering with each other.

[0011] Further, the battery taking station and the charging station can also be combined to provide replacement (e.g., full) battery boxes and receive depleted battery boxes for charging.

[0012] In addition, the utility model also provides a battery replacement station of the relay battery replacement device of the battery replacement station.

[0013] The battery replacement station includes a battery replacement station, a battery taking station, a charging station, and the relay battery replacement device. The battery replacement station provides a vehicle parking position, the battery taking station is provided with a corresponding battery compartment, etc., and the charging station receives depleted battery boxes for charging. Preferably, the battery taking station and the charging station in the battery replacement station can also be combined.

[0014] In addition, the device of the utility model also provides a battery replacement method for replacing battery boxes for vehicles, including the following steps:

[0015] (1)Battery pre-hoisting: the first trolley crane will replace the full battery from the battery taking position and hoist to the appropriate height;

[0016] (2)Trolley crane pre-positioning: the second trolley crane will pre-position the trolley crane to the battery position on the vehicle after the vehicle is parked;

[0017] (3)Vehicle entry: the vehicle is driven to the designated position;

[0018] (4)Lowering the empty trolley crane: the second trolley crane is lowered;

[0019] (5)Grabbing and hoisting: the second trolley crane grabs the depleted battery on the vehicle and hoists it to a certain height;

[0020] (6)Double battery movement: the second trolley crane moves away, and the first trolley crane moves the full battery to the position above the vehicle;

[0021] (7)Lowering the full battery: the first trolley crane is lowered, and the full battery falls onto the vehicle; at the same time, the second trolley crane transports the depleted battery back to the charging position;

[0022] (8)Hoisting and moving away: the first trolley crane is hoisted and moved away from the vehicle;

[0023] (9)Vehicle exit: the vehicle loaded with the full battery exits the battery swapping station.

[0024] Compared with the prior art, in the above-mentioned relay battery swapping device and battery swapping station, when the vehicle is being swapped, the full battery box is loaded, after the second trolley crane takes the depleted battery box from the vehicle, the first trolley crane can immediately move the full battery box loaded to the vehicle, completing the transfer and replacement of the battery box, avoiding the need to replace the battery box from another location and return to the swapping position after taking the battery box of the vehicle in the existing swapping process, thereby reducing the travel distance in the swapping process and improving the swapping efficiency of the vehicle.
