[0023] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0024] Reference Figures 1 to 5 A mobile power exchange device includes a power receiving device 1 and a power exchange device 2. The power receiving device 1 is provided with a power receiving platform 11 for automatically disassembling and assembling a battery A. The power exchange device 2 includes a storage bin 21, a transition bin 22 and a grabbing mechanism 23. The grabbing mechanism 23 is arranged above the storage bin 21 and the transition bin 22, and is used to carry the battery A back and forth between the storage bin 21 and the transition bin 22. The side wall of the transition bin 22 is provided with a transfer bridge 24 that can be vertically flipped, and is used to bridge the power receiving platform 11 and transfer the battery A back and forth between the transition bin 22 and the power receiving platform 11. When replacing power, the transfer bridge 24 is overlapped with the power receiving platform 11 to form a power exchange channel between the power receiving device 1 and the power exchange device 2. The grabbing mechanism 23 carries the designated battery A in the storage bin 21 to the transition bin 22, and transfers it to the power receiving platform 11 through the transfer bridge 24. Finally, the power receiving platform 11 automatically completes the battery installation process, thereby realizing the power exchange process. It should be noted that the original battery on the power receiving device 1 has been moved back to the storage compartment 21 of the battery exchange device 2 by the above reverse process, so the process is not repeated here. The design of the battery exchange compartment 22 and the transfer bridge 24 in the present invention makes the spatial layout of the battery exchange device 2 more compact, shortens the battery exchange operation route, effectively improves the battery exchange efficiency, and can realize automatic battery exchange operation, which has the advantages of simple structure, ingenious design, convenient operation and strong practicality.

[0025] Reference Figures 1 to 5 The storage bin 21 includes a storage rack 211 and a shell 212 covering the outside of the storage rack 211; the storage rack 211 is provided with a plurality of slots 213 for placing batteries A, and is equipped with a fixed lock block 214 for fixing batteries A. Specifically, a door is provided at the rear end of the shell 212 to facilitate loading and unloading and management of batteries A; the fixed lock block 214 is controlled by the battery exchange system. When it is determined which battery A needs to be transported, the battery exchange system controls the fixed lock block 214 to unlock, and the grabbing mechanism 23 is used to transport it.

[0026] Reference Figures 1 to 5The grabbing mechanism 23 includes a guide rail 231 and a crane 232; the guide rail 231 is fixed above the storage bin 21 and the transition bin 22, the crane 232 can be slidably arranged on the guide rail 231, and a claw plate 233 for grabbing the battery A is arranged below the crane 232. Specifically, at least one positioning groove is arranged on both sides of the exterior of the battery box of the battery A, and the claw plate 233 is provided with a plurality of claw hooks adapted to the positioning groove, thereby ensuring that the claw plate 233 can effectively clamp the battery A to prevent it from falling during transportation. However, the structure of the grabbing mechanism 23 is not limited to this, and in actual applications, a grabbing mechanism such as a manipulator that can realize battery transportation can also be used.

[0027] Reference Figures 1 to 5 The battery exchange device 2 further includes a shift mechanism 25, which is disposed in the transition bin 22 and is used to push the battery back and forth between the transition bin 22 and the transfer bridge 24. Specifically, the shift mechanism 25 includes a shift plate 251 and a push block 252; the shift plate 251 is fixed at the bottom of the transition bin 22, and a plurality of rollers 253 are disposed in the shift plate 251 for driving the battery A to move laterally; two push blocks 252 are disposed on both sides of the shift plate 251 through a screw rod (not shown in the figure) so as to be able to reciprocate laterally, and are used to push the battery A on the shift plate 251 to the transfer bridge 24. When replacing the battery, the grabbing mechanism 23 moves the designated battery A in the storage bin 21 to the shifting plate 251 of the transition bin 22. The two push blocks 252 push the battery A laterally under the action of the screw rod. At the same time, the roller 253 at the bottom of the shifting plate 251 rotates at the same time, pushing the battery A to move laterally from the bottom, thereby quickly pushing the battery A to the transfer bridge 24 for the next step of the battery replacement operation. The design of the shifting mechanism 25 makes the structure of the transition bin more compact and further improves the efficiency of battery replacement.

[0028] Reference Figures 1 to 5 , the transfer bridge 24 includes a warehouse wall plate 241, a guide plate 242 and a first conveying crawler 243; one end of the warehouse wall plate 241 can be vertically flipped and hinged to the side wall of the transition warehouse 22, and the other end of the warehouse wall plate 241 is overlapped on the power receiving platform 11. The middle part of the warehouse wall plate 241 is provided with a first conveying crawler 243, and guide plates 242 for preventing the battery A from running are fixed on both sides of the first conveying crawler 243. When the battery is not replaced, the warehouse wall plate 241 is the side wall plate of the transition warehouse. When the battery is replaced, the warehouse wall plate 241 is flipped downward to horizontally overlap the power receiving platform 11, thereby forming a power replacement channel between the power receiving device 1 and the power replacement device 2. The shifting mechanism 25 pushes the battery A onto the first conveying crawler 243, and transfers the battery A to the power receiving platform 11 through the first conveying crawler 243. In this process, the design of the guide plate 242 can play a guiding and positioning role, effectively preventing the battery A from running, and ensuring that it enters the power receiving platform 11 smoothly. In practical applications, if necessary, the transfer bridge 24 can be provided on both side walls of the transition bin 22, thereby making the battery replacement process more flexible and convenient.

[0029] Reference Figure 1 and Figure 2 In order to facilitate internal inspection and maintenance, a bin cover 221 is provided on the top of the transition bin 22, and the bin cover 221 is flipably hinged to the shell 212 of the storage bin through a cylinder matching connection assembly.

[0030] Reference Figures 1 to 5 The power receiving platform 11 includes a support plate 111, a second conveying crawler 112 and a lifting mechanism (not shown in the figure); the power receiving device 1 is provided with a power receiving compartment (not shown in the figure) for installing batteries; the support plate 111 can be lifted up and down in the power receiving compartment through the lifting mechanism, and the support plate 111 is provided with a second conveying crawler 112 connected to the first conveying crawler 243 at one end close to the power exchange device 2. The support plate 111 is provided with a plurality of positioning lock blocks 113 for clamping the battery A on both sides thereof, and a stopper 114 for preventing the battery A from falling off is provided at the end away from the second conveying crawler 112. After the screw rod of the push block 252 reaches the end of its stroke, the first conveyor belt 243 and the second conveyor belt 112 begin to work together to reliably convey battery A to the specified position of the support plate 111. After confirming that battery A has reached the specified position, the power receiving system activates multiple positioning lock blocks 113 to clamp battery A on the support plate 111. The support plate 111 falls into the power receiving compartment under the action of the lifting mechanism, so that the power supply interface of battery A and the power interface at the bottom of the power receiving compartment are reliably connected, thereby completing the battery replacement operation.

[0031] Reference Figures 1 to 5 In order to ensure that the transfer bridge 24 is reliably connected to the power receiving platform 11, a position sensor can be set between the two. After the two are successfully connected, the battery handling program can be started. In addition, in order to ensure stable connection and safe battery replacement, an automatic lock or a mutually cooperating mortise and tenon structure can be set between the two. Those skilled in the art can refer to the above description to understand and implement it, so it will not be repeated here.

[0032] Reference Figures 1 to 5 As a preferred solution: the battery exchange device 2 and the power receiving device 1 are both transformed from logistics trucks. Specifically, the storage compartment 21 of the battery exchange device 2 is set in the cargo compartment of the logistics truck; the transition compartment 21 of the battery exchange device 2 and the power receiving platform 11 of the power receiving device 1 are both set between the driving compartment and the cargo compartment of the logistics truck. The design concept of mobile battery exchange can be realized by low-cost transformation of existing logistics trucks, which effectively saves production costs and makes mobile battery exchange technology widely applicable to the field of new energy logistics.

[0033] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
