[0002] With the maturity of technology and the increasing attention paid by the country and society to environmental protection, electric vehicle technology has developed rapidly in recent years; accordingly, more and more electric heavy trucks have been put into use in production sites such as factories and docks;

[0003] Unlike ordinary family cars, which can be charged using charging piles during rest time at night, heavy trucks, as important production and transportation facilities, need to be kept in use for a long time. When their power is exhausted, it is preferred to quickly replace the battery pack so that the truck can be quickly put into production again. However, the battery pack replacement process for heavy trucks in battery swap stations in the prior art is cumbersome and slow, and only one battery can be replaced at a time. The operation is not convenient, which affects the replacement efficiency. Therefore, a battery swap station for heavy truck battery replacement is proposed to solve the above problems.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 In this embodiment, a battery swap station for heavy trucks is used to replace batteries. Two first three-dimensional battery compartments 11, a second three-dimensional battery compartment 18, a first RGV robot 13, and a second RGV robot 16 are arranged on both sides of the aisle. The middle aisle 15 can pass heavy trucks, such as Figure 1 As shown;

[0024] The battery pack brackets on both sides of the heavy truck are provided by the present solution. The bracket mounting surface 21 is mounted on both sides of the heavy truck. The rotating lock 22 can lock the battery pack. Figure 2 As shown;

[0025] In addition to the equipment hardware, this solution is also equipped with a complete station control system, which includes a three-dimensional battery bin system [used to control the operation of the lifting vehicle 56 and the automatic telescopic fork 57 in the three-dimensional battery bin], an RGV robot system [used to control the operation of the first RGV robot 13 and the second RGV robot 16], a first visual system 12 and a second visual system 17 [used to monitor, record and control the angle of the battery pack entering and exiting the three-dimensional battery bin, so as to facilitate one-step installation], a parking assistance system [including vision, laser and voice to assist the driver to park the heavy truck in place], a charging module system [used to control the charging and battery charging status in the three-dimensional battery bin], a cooling system [used to control the cooling of the entire set of equipment], and a fire fighting system [used to monitor the temperature of the entire set of equipment and fire fighting after problems occur]. There is also a vehicle-mounted system T-BOX parallel to the station control system [used to monitor the use of the vehicle-mounted battery and control the unlocking and locking of the rotating lock 22]. The station control system and the vehicle-mounted system are connected to each other in communication to ensure synchronization and automatic operation;

[0026] When the heavy truck uses up a set amount of electricity, the T-BOX installed at the bottom of the heavy truck will remind the driver to go to the battery swap station for battery swap. The T-BOX is provided by this solution, and the T-BOX will communicate with the station control system. After the heavy truck drives to the middle aisle 15, the parking assistance system of the charging stereoscopic warehouse will prompt the heavy truck whether it has parked in place. After parking, the T-BOX automatically opens the rotating lock 22 by controlling the electric propulsion device 41, such as Figure 3 , Figure 4 As shown;

[0027] After the rotary lock 22 is automatically opened, the first RGV robot 13 and the second RGV robot 16 on both sides of the three-dimensional battery warehouse automatically walk to the bottom of the heavy truck battery pack, and then the first RGV robot 13 and the second RGV robot 16 rise to lift the battery pack above the rotary lock 22, and the battery pack is separated from the heavy truck. Then the first RGV robot 13 and the second RGV robot 16 transport the battery pack to the three-dimensional battery warehouse, as shown in FIG. Figure 1 As shown. The first RGV robot 13 and the second RGV robot 16 can move up and down, left and right, forward and backward in the illustrated position, and the top platform can rotate. The first RGV robot 13 and the second RGV robot 16 system, in conjunction with the visual systems 12 and 17 of the charging station, can correct the orientation deviation of the battery pack caused by the improper parking of the heavy truck, so that it can accurately fall into the standard position 54, and at the same time, when transporting the fully charged battery pack to the heavy truck, it should be installed in the direction of the heavy truck;

[0028] After the first RGV robot 13 and the second RGV robot 16 transport the battery packs to the three-dimensional battery warehouse, the battery warehouse system will control the lifting vehicle 56 and the automatic telescopic fork 57 on the lifting vehicle through the servo motor 51, the transmission rod 52, and the transmission chain 53 in the three-dimensional battery warehouse to first transport the battery packs without power to the standard position 54, and then the lifting vehicle 56 and the automatic telescopic fork 57 will transport the fully charged battery packs from other charging positions 58 to the first RGV robot 13 and the second RGV robot 16. Figure 5 As shown;

[0029] The first RGV robot 13 and the second RGV robot 16 then transport the fully charged battery pack to the battery pack bracket of the heavy truck and place it on the rotating lock 22. The station control system notifies the T-BOX to lock the battery pack. At this time, the onboard system will perform a self-check on the battery. After the self-check passes, the heavy truck drives away and the battery replacement is completed.

[0030] It is mentioned that the automatic telescopic fork 57 places the fully charged battery pack on the first RGV robot 13 and the second RGV robot 16. After the first RGV robot 13 and the second RGV robot 16 transport the battery pack, the lifting vehicle 56 and the automatic telescopic fork 57 will transport the battery pack on the standard position 54 to the charging position 58 for charging. This is done for overall operating efficiency.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
