[0002] In modern life, whether it is for the need of low-carbon life or for the convenience of life, social shared green energy products are becoming more and more abundant. For movable shared green energy products, in order to ensure long-term use, they must either have a fixed charging scene or a design that allows convenient battery replacement. For small products such as power banks, having a fixed charging scene is relatively economical and convenient. However, for larger electrical appliances such as bicycles, a design that allows convenient battery replacement is obviously more suitable. So how can battery replacement be made convenient?

[0003] In the prior art, the user needs to open the space on the appliance for placing the mobile power supply, take out the exhausted mobile power supply, and put in a new fully charged mobile power supply. Since the mobile power supply itself needs to be protected from external damage, the space for placing the mobile power supply is mostly relatively sealed, and the mobile power supply also needs to be limited, which makes replacing the mobile power supply more complicated.

[0004] In summary, the replacement convenience of mobile power supplies in the prior art is relatively poor, so there is room for further improvement. Summary of the invention

[0067] Furthermore, in the present embodiment, a first groove 11 is provided on the lower side of the limit block 8, an inner cavity is provided on the right end of the second fixing member 4, a first through hole 13 is provided on the side wall of the inner cavity, the circulating track member 5 is located in the inner cavity, a circulating track is provided on the upper side of the circulating track member 5, and a first protrusion 12 for cooperating with the first through hole 13 is integrally formed on the lower part of the side wall of the circulating track member 5. The circulating track member 5 is stably installed in the inner cavity of the second fixing member 4 through the cooperation of the first protrusion 12 and the first through hole 13, and the upper part of the circulating track member 5 is slidably connected with the first groove 11 of the limit block, so that the limit block 8 can also be slid into the inner cavity of the second fixing member 4.

[0068] Furthermore, in the present embodiment, the axial hole length of the second through hole 15 is smaller than the axial length of the charge and discharge port 14, so that when the second fixing member 4 is in a connected state with the first fixing member 3, the charge and discharge port 14 of the first fixing member 3 can pass through the second through hole 15 of the second fixing member 4 to be electrically connected to the battery pack 20, but when the second fixing member 4 is in a pop-up state with the first fixing member 3, the end of the charge and discharge port 14 is located in the second through hole 15, so that the first fixing member 3 is not connected to the battery pack 20, thereby, the charge and discharge port 14 guides the second fixing member 4, ensures the accuracy of the operation between the second fixing member 4 and the first fixing member 3, and when the battery pack 20 is in the pop-up state, the second through hole 15 of the second fixing member 4 can also isolate the charge and discharge port 14 and the battery pack 20, to prevent the battery pack 20 from being intermittently connected to the charge and discharge port 14 during the replacement process.

[0069] Furthermore, in this embodiment, the connection component 2 may also be in other forms, as long as the connection component 2 can connect or release the battery pack 20 as the relative distance between the second fixing member 4 and the first fixing member 3 changes.

[0070] Furthermore, in this embodiment, the connection shell 16 may have a cavity 19 , so that the connection shell 16 accommodates the battery pack 20 or a part of the battery pack 20 through the cavity 19 .

[0071] Furthermore, in this embodiment, the side surfaces of the battery pack 20 are all different, so that the battery pack has only one insertion form.

[0075] A permanent magnet 25 is disposed on one end of the battery pack 20 , and a power output jack for electrical connection is also disposed at the end of the battery pack 20 .

[0076] The storage assembly includes a storage shell 26, one end of which is provided with a charging and discharging port 14 for electrically connecting to the battery pack 20. The limiting assembly includes an electromagnet 24 and a commutator. The electromagnet 24 is arranged at the end of the storage shell 26, so that the electromagnet 24 can attract or repel the permanent magnet 25 on the battery pack 20 when energized. The commutator is electrically connected to the electromagnet 24, so that the commutator can change the direction of current, thereby changing the magnetic pole of the electromagnet 24. The battery pack 20 is attracted or repelled by the change of the magnetic pole of the electromagnet 24, thereby achieving the limitation or ejection of the battery pack 20.
