[0053] With the development of new energy technology, the use of battery equipment increases. When the power of the electrical equipment is exhausted, the power can be supplemented by connecting the charging equipment, for example, electric vehicles can be connected to the charging pile for charging. Compared with the way of connecting the charging equipment to supplement the power, replacing the battery can achieve faster power supplement. Currently, there is also a battery replacement station specially used for replacing the battery. The battery replacement station includes a battery replacement station body, and the battery replacement station body has a battery replacement channel. The battery replacement station body is provided with a battery storage device and a battery replacement device. The battery replacement channel is used for parking vehicles, and the battery storage device is used for storing batteries. When battery replacement is needed, the vehicle is parked in a specified area in the battery replacement channel, the battery replacement device removes the discharged battery of the vehicle, and the battery is transported to the battery storage device through related equipment. The full battery on the battery storage device is installed on the vehicle through the battery replacement device to achieve vehicle battery replacement. During the whole life of the battery replacement station, the battery needs to be exchanged with the outside, for example, the old battery is taken out from the battery storage device to the outside for maintenance, renovation or recycling, and the well-maintained battery or new battery from the outside is placed in the battery storage device to realize the updating and maintenance of the battery, so as to provide good battery for vehicle battery replacement.

[0054] Currently, a forklift is often used to transport the battery from outside the station to inside the station or to transport the battery from inside the station to outside the station. For example, a transfer trolley transports the battery, the forklift unloads the battery from the transfer trolley and moves the battery to inside the station, and then forks the battery into the station. However, the forklift operation is difficult and has high positioning requirements, resulting in low battery transfer efficiency and affecting the working efficiency of the battery replacement station.

[0055] In view of this, in order to improve the low transfer efficiency of the forklift and affect the working efficiency of the battery replacement station, some embodiments of the present application provide a transfer device applied to a battery replacement station. The transfer device includes a rack and a hoisting mechanism. The rack is used to be rotatably connected to the battery replacement station body. The hoisting mechanism is used to hoist the battery. The hoisting mechanism is connected to the rack, and the rack is used to drive the hoisting mechanism to switch between a first position located inside the battery replacement station and a second position located outside the battery replacement station.

[0056] In the above scheme, the transfer device is arranged in the battery replacement station, and the rack is rotatably connected to the battery replacement station body. Through the rotation of the rack, the battery can be quickly transferred between the first position and the second position, so as to realize the quick battery exchange between the battery replacement station and the outside, improve the updating and maintenance efficiency of the battery of the battery replacement station, and further improve the working efficiency of the battery replacement station.

[0057] The battery swap station disclosed by the embodiments of the present application can be used for replacing the batteries of vehicles, but is not limited to this, and can also be used for replacing the batteries of other power-consuming devices such as ships, aircrafts and the like, for example, electric toys, electric tools, electric cars, electric vehicles, ships, spacecrafts and the like.

[0065] The frame 11 is a structural member that can be directly or indirectly connected to the battery swap station body 101, and the frame 11 is rotatable relative to the battery swap station body 101. The rotation axis of the frame 11 (indicated by O in FIG. 2) can be parallel to the direction of gravity z.

[0066] For example, the frame 11 can be arranged near the warehouse door of the battery swap station body 101, and is directly or indirectly connected to the wall of the battery swap station body 101 through bearings or shafts, etc. "Indirectly" can be understood as, in some embodiments, the wall of the battery swap station body 101 and the frame 11 can be connected through additional support structural members.

[0067] In some embodiments, the frame 11 can be made of aluminum alloy, stainless steel or other metals.

[0068] In some embodiments, the rack 11 can be configured with a driving device capable of driving the rack 11 to rotate relative to the battery swap station body 101. For example, the driving device is a driving motor driving the rack 11 to rotate. In some embodiments, the rack 11 can be driven to rotate relative to the battery swap station body 101 by manually pushing the rack 11.

[0069] The hoisting mechanism 12 is used for hoisting the battery 20, and can lift the battery 20 from the ground or other positions to a certain height, and cooperate with the rotation of the rack 11 to realize the transfer of the battery 20. In some embodiments, the hoisting mechanism 12 can be switched between the first position and the second position by rotating the rack 11 by 90 degrees, 180 degrees or other angles.

[0070] For example, the transfer trolley transports the battery 20 to the second position; the hoisting mechanism 12 is switched to the second position by rotating the rack 11, the hoisting mechanism 12 grabs the battery 20 on the transfer trolley and lifts the battery 20 to a certain height so that the battery 20 is separated from the transfer trolley; the rack 11 is rotated by 90 degrees, the hoisting mechanism 12 is switched to the first position inside the battery swap station 100, the hoisting mechanism 12 releases the battery 20 to the first position, and other devices inside the battery swap station 100 transport the battery 20 at the first position to the battery storage device.

[0071] In the above scheme, the transfer device 10 is arranged in the battery swap station 100, and the rack 11 is rotatably connected with the battery swap station body 101, and by rotating the rack 11, the battery 20 can be quickly transferred between the first position and the second position, so as to realize the quick exchange of the battery 20 between the battery swap station 100 and the outside world, improve the updating and maintenance efficiency of the battery 20 of the battery swap station 100, and further improve the working efficiency of the battery swap station 100.

[0072] According to some embodiments of the present application, one end of the rack 11 is used for rotatable connection with the battery swap station body 101, and the other end is provided with a hand holding member 15 for holding the hand to push the rack 11 to rotate relative to the battery swap station body 101.

The battery 20 can be fixed by the clamping of the mechanical hand, and the battery 20 is lifted by the lifting of the lifting mechanism 13. Alternatively, the grabbing mechanism 14 comprises a hook. The hook can hook the groove on the battery 20, and the battery 20 is lifted by the lifting of the lifting mechanism 13.

[0079] In the above solution, the lifting mechanism 13 and the grabbing mechanism 14 are cooperated, so that the battery 20 can be effectively grabbed away from the support surface. On the one hand, the risk of surface damage of the battery 20 caused by the friction between the battery 20 and the support surface can be reduced. On the other hand, the battery 20 can be quickly transferred between the inside and outside of the battery swap station 100 by cooperating with the rotation of the rack 11.

[0080] According to some embodiments of the present application, referring to FIG. 2, the grabbing mechanism 14 comprises a support 140 and a plurality of grabbing members 141.

For example, the support 140 comprises a plurality of cross beams and a plurality of vertical beams. The plurality of cross beams and the plurality of vertical beams are welded to form a square frame structure. The lifting mechanism 13 can be connected with the middle part of the support 140.

[0082] The grabbing mechanism 14 comprises a plurality of grabbing members 141, which are respectively connected with the support 140 and are respectively located at different positions. Each grabbing member 141 can grab the battery 20 to form a connection therebetween, thereby enabling the battery 20 to be moved.

[0083] In some embodiments, referring to FIG. 5 and FIG. 6, FIG. 5 is a schematic view of the transfer device 10 and the battery 20 in some embodiments of the present application, and FIG. 6 is a schematic view of the transfer device 10 and the battery 20 in some embodiments of the present application. The plurality of grabbing members 141 can respectively act on at least two opposite sides of the battery 20. For example, along the width direction of the battery 20, part of the grabbing members 141 are located on one side of the width direction of the battery 20, and the other part of the grabbing members 141 are located on the other side of the width direction of the battery 20.

[0084] In the above scheme, on the one hand, by arranging the plurality of grabbing members 141, the transfer device 10 can effectively grab the battery 20, and the risk of the battery 20 falling off is reduced.

[0089] In some embodiments, the hook 1413 can be made of aluminum alloy, stainless steel, carbon steel or the like.

[0090] In some embodiments, the hook 1413 can be directly or indirectly rotatably connected between the bracket 140 and the hook 1413, so that the hook 1413 has a certain degree of freedom, can be placed into the card slot 21 and engaged with the upper edge of the card slot 21, and can be taken out of the card slot 21.

[0091] In the above scheme, the hook 1413 cooperates with the card slot 21 of the battery 20, which can efficiently connect or efficiently disconnect from the battery 20, so that the transfer device 10 has high transfer efficiency.

[0093] The anti-falling piece 1410 is used to prevent the hook 1413 from falling out of the card slot 21 of the battery 20.

[0094] In some embodiments, the anti-falling piece 1410 is movably connected with the hook 1413, so that the position of the anti-falling piece 1410 is adjustable relative to the hook 1413, so that the position of the anti-falling piece 1410 can be adjusted to enable the anti-falling piece 1410 to engage with the lower edge of the card slot 21 to limit the hook 1413 from being taken out of the card slot 21, or enable the anti-falling piece 1410 to be separated from the lower edge of the card slot 21, so that the hook 1413 can be taken out of the card slot 21.

[0095] Optionally, the anti-falling piece 1410 is hinged to the hook 1413, and the anti-falling piece 1410 can be deflected relative to the hook 1413, one end of the anti-falling piece 1410 can be provided with a bent portion 14100, which is used for clamping the lower edge of the clamping groove 21, and the other end of the anti-falling piece 1410 is used for pulling, so as to deflect the anti-falling piece 1410. Illustratively, by pulling the other end of the anti-falling piece 1410, the bent portion 14100 is deflected downward to be clamped on the lower edge of the clamping groove, or the bent portion 14100 is deflected upward to be separated from the lower edge of the clamping groove.

[0096] Optionally, the anti-falling piece 1410 is slidably connected to the hook 1413 in the direction of gravity, and the anti-falling piece 1410 can be clamped on the lower edge of the clamping groove 21 by moving the anti-falling piece 1410 downward, and the anti-falling piece 1410 can be separated from the lower edge of the clamping groove 21 by moving the anti-falling piece 1410 upward. Illustratively, a driving device is arranged between the anti-falling piece 1410 and the hook 1413, and the driving device can be a mechanism capable of outputting linear motion, such as a cylinder, a linear motor, or a single-axis mechanical arm, etc., and the driving device can drive the anti-falling piece 1410 to ascend and descend to change the position of the anti-falling piece 1410.

[0097] In the above scheme, when the hook 1413 is clamped on the upper edge of the clamping groove 21 of the battery 20, the anti-falling piece 1410 can abut the lower edge of the clamping groove 21, thereby locking the hook 1413 in the clamping groove 21, limiting the hook 1413 from separating from the clamping groove 21, effectively reducing the risk of the battery 20 falling off the transfer device 10, and making the transfer device 10 have higher reliability.

[0098] According to some embodiments of the present application, the grabbing piece 141 further comprises a resilient piece 1411. The anti-falling piece 1410 is hinged to the side of the hook 1413 away from the bracket 140, the end of the anti-falling piece 1410 is provided with a bent portion 14100 for clamping the lower edge of the clamping groove 21, and the resilient piece 1411 is arranged between the anti-falling piece 1410 and the hook 1413, for providing the anti-falling piece 1410 with an elastic force, so that the anti-falling piece 1410 has a tendency to deflect relative to the hook 1413 to move the bent portion 14100 to the side away from the hook 1413.

[0099] In some embodiments, the hinge axis between the anti-falling piece 1410 and the hook 1413 can be parallel to the horizontal plane. Alternatively, the middle part of the anti-falling piece 1410 is hinged to the lower end of the hook 1413 through the hinge shaft 1412, so that the two ends of the anti-falling piece 1410 can swing up and down relative to the hook 1413. The elastic piece 1411 is used to provide an elastic force to the anti-falling piece 1410, so that the anti-falling piece 1410 is deflected, and the bent part 14100 has a tendency to be deflected to the side away from the hook 1413 to be clamped to the lower edge of the clamping groove 21. When the bent part 14100 is clamped to the lower edge of the clamping groove 21, the bent part 14100 can define the position of the hook 1413 relative to the clamping groove 21 in the direction of gravity z, and lock part of the hook 1413 in the clamping groove 21.

[0100] Alternatively, referring to FIGS. 7 and 8, the inner side of the hook 1413 faces the battery 20, and the lower end of the hook 1413 is formed with an opening that penetrates the inner and outer sides of the hook 1413. The anti-falling piece 1410 is arranged in the opening and can swing relative to the hook 1413 through the hinge shaft 1412, and the two ends of the anti-falling piece 1410 are located outside the opening, one end of which is provided with the bent part 14100, and the other end is provided for an operator or equipment to pull to deflect the anti-falling piece 1410.

[0101] The elastic piece 1411 is arranged in the opening and connected to the hook 1413 and the anti-falling piece 1410, and the bent part 14100 is arranged perpendicularly relative to the main body of the anti-falling piece 1410. When the elastic piece 1411 is in a natural state, the bent part 14100 is at the lowest part of the anti-falling piece 1410, so as to be clamped to the lower edge of the clamping groove 21, thereby limiting the hook 1413 from being pulled out. When it is necessary to take out the hook 1413, the operator or equipment pulls the end of the anti-falling piece 1410 away from the battery to overcome the elastic force of the elastic piece 1411, so that the bent part 14100 moves upward, thereby canceling the clamping to the lower edge of the clamping groove 21, so as to be able to pull out the hook 1413 from the clamping groove.

[0102] In some embodiments, the elastic piece includes but is not limited to a spring, a rubber block or other structural member capable of providing an elastic force to the anti-falling piece 1410.

[0103] In the above scheme, by arranging the elastic piece 1411, the bent part 14100 always has a tendency to move to the side away from the hook 1413, so that when the hook 1413 is clamped to the clamping groove 21 of the battery 20, the bent part 14100 can effectively be clamped to the lower edge of the clamping groove 21, thereby realizing the locking between the hook 1413 and the battery, effectively reducing the risk of the battery 20 falling off the transfer device 10, and making the transfer device 10 have higher reliability.
