[0029] Embodiment 1:

[0030] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , a split portable energy storage power supply, comprising an inverter module 10 and a battery module 20, wherein the inverter module 10 and the battery module 20 are separately arranged, and the inverter module 10 and the battery module 20 are stacked.

[0031] The inverter module 10 is electrically connected to the battery module 20 through a connection component. The connection component includes a male connector 100 and a female connector 200 that mates with the male connector 100. The inverter module 10 protrudes with the male connector 100 towards the battery module 20, and the battery module 20 protrudes with the female connector 200 towards the inverter module 10.

[0032] In this embodiment, the split-type portable energy storage power supply can be configured with multiple battery modules 20. When one of the battery modules 20 electrically connected to the inverter module 10 runs out of power, the battery module 20 can be detached and replaced with another battery module 20 with power to extend the usage duration of the split-type portable energy storage power supply, thus facilitating the use by the user.

[0033] As described above, for the split-type portable energy storage power supply proposed by the present utility model, through the split arrangement of the inverter module 10 and the battery module 20, on the one hand, the battery module 20 can be detachably replaced, and on the other hand, the split-type portable energy storage power supply is decomposed into at least two parts, which can be carried by multiple people to achieve the function of portability; through the cooperation of the male connector 100 and the female connector 200, the inverter module 10 and the battery module 20 can be electrically connected by plugging, avoiding connection through additional wires, and realizing the convenience of disassembly between the inverter module 10 and the battery module 20. The split-type portable energy storage power supply can not only conveniently detach and replace the battery module 20, but also is convenient to carry.

[0034] At least one detection unit is provided on the female connector 200 and / or the male connector 100. The detection unit is used to detect the connection status of the connection component.

[0035] After the male connector 100 is plugged into the female connector 200, the detection unit detects whether the male connector 100 is fully inserted into the female connector 200; if it is detected that the male connector 100 is fully inserted into the female connector 200, the detection unit connects the circuit between the inverter module 10 and the battery module 20 to achieve power-on; if it is detected that the male connector 100 is not fully inserted into the female connector 200, the detection unit disconnects the circuit between the inverter module 10 and the battery module 20 to achieve power-off; the detection unit plays a role in improving the usage safety of the split-type portable energy storage power supply.

[0036] In this embodiment, the inverter module 10 is stacked above the battery module 20, and the inverter module 10 is electrically connected to the battery module 20.

[0037] Please refer to Figure 2 ,Figure 5 and Figure 6 The inverter module 10 protrudes towards the battery module 20 with a first positioning boss 11. A plugging slot 111 for accommodating the connecting male head 100 is recessed in the first positioning boss 11. A first positioning sunk table 21 that cooperates with the first positioning boss 11 is recessed in the battery module 20. The cooperation between the first positioning boss 11 and the first positioning sunk table 21 is used to align the connecting male head 100 with the connecting female seat 200, playing a positioning role during the installation of the inverter module 10 on the battery module 20.

[0038] Furthermore, the side wall of the first positioning boss 11 inclines towards the inside of the first positioning boss 11 along the direction close to the battery module 20, and the inner side wall of the first positioning sunk table 21 inclines towards the outside of the first positioning sunk table 21 along the direction close to the inverter module 10. Such a setting facilitates the cooperation between the first positioning boss 11 of the inverter module 10 and the first positioning sunk table 21 of the battery module 20, and is convenient for the user to disassemble and assemble the battery module 20.

[0039] Please refer to Figures 4 - 6 . The inverter module 10 is circumferentially provided with a limiting protrusion 12 around the connecting male head 100. The battery module 20 is circumferentially provided with a limiting seat 22 around the connecting female seat 200. A limiting groove 221 that cooperates with the limiting protrusion 12 is recessed in the limiting seat 22. The cooperation between the limiting protrusion 12 and the limiting seat 22 plays a further positioning role for the inverter module 10 and the battery module 20, thereby further aligning the connecting male head 100 with the connecting female seat 200.

[0040] Since the cross-sections of both the connecting male head 100 and the connecting female seat 200 are non-centrally symmetric shapes, when plugging the connecting male head 100 into the connecting female seat 200, it is necessary to align a direction to successfully plug in.

[0041] Therefore, further, the cross-sections of both the limiting seat 22 and the limiting protrusion 12 are also non-centrally symmetric shapes. Such a setting can play an anti-misoperation role. On the one hand, it is convenient for the user to successfully plug the connecting male head 100 of the inverter module 10 into the connecting female seat 200 of the battery module 20. On the other hand, it avoids damage to the connecting male head 100 or the connecting female seat 200 caused by plugging the connecting male head 100 into the connecting female seat 200 in the wrong direction.

[0042] Please refer to Figures 1 - 5 and Figures 7 - 9 . The inverter module 10 and the battery module 20 are locked through a buckle structure.

[0043] The locking structure is located at the connection between the inverter module 10 and the battery module 20. The locking structure includes a locking member 30, a locking groove 112, and a guiding groove 211 that cooperates with the locking groove 112.

[0044] The locking groove 112 is formed on the side wall of the first positioning boss 11 of the inverter module 10. The guiding groove 211 is formed through the side wall of the first positioning sunk platform 21 of the battery module 20. The locking member 30 is slidably arranged along the guiding groove 211, and one end of the locking member 30 passes through the guiding groove 211 and is slidably arranged in the locking groove 112.

[0045] More specifically, the locking member 30 includes a sliding block 31 and a pushing block 32 connected to the sliding block 31. The sliding block 31 passes through the guiding groove 211 and is slidably arranged in the locking groove 112. The pushing block 32 is slidably arranged on the side wall of the battery module 20. An anti - detachment block 33 is arranged on the sliding block 31, and the anti - detachment block 33 is used to prevent the locking member 30 from detaching from the guiding groove 211.

[0046] The locking groove 112 is provided with an unlocking groove 1121 in the direction towards the battery module 20, and the unlocking groove 1121 extends to the lower surface of the first positioning boss 11. The unlocking groove 1121 is used to release the locking of the inverter module 10 and the battery module 20 by the locking member 30.

[0047] When it is necessary to lock the inverter module 10 and the battery module 20, the user can push the pushing block 32 to make the sliding block 31 slide along the guiding groove 211 and away from the unlocking groove 1121 to achieve the purpose of locking. When it is necessary to disassemble and replace the battery module 20, the user can push the pushing block 32 to make the sliding block 31 slide above the unlocking groove 1121, and then lift the inverter module 10 to make the sliding block 31 pass through the unlocking groove 1121 and detach from the locking groove 112 to achieve the purpose of unlocking.

[0048] Furthermore, the length of the unlocking groove 1121 in the horizontal direction is greater than the length of the sliding block 31 in the horizontal direction to ensure that the sliding block 31 can detach from the locking groove 112 through the unlocking groove 1121.

[0049] Please refer to Figure 5 , a pair of hand - holding grooves 23 are recessed on the side wall of the battery module 20. The pair of hand - holding grooves 23 facilitate the user to pick up the battery module 20. A battery pack is arranged in the battery module 20, and the battery pack is electrically connected to the connection base 200.

[0050] A power control module is provided on the inverter module 10, and the power control module is electrically connected to the male connector 100; the power control module includes an inverter. A heat dissipation device is further provided on the inverter module 10, and the heat dissipation device dissipates heat through the heat dissipation holes on the side wall of the inverter module 10 to achieve the thermal management of the inverter module 10.

[0051] More specifically, a display panel 13, an input plug-in module 14, and an output plug-in module 15 are provided on the side wall of the inverter module 10.
