[0033] An energy storage power supply according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0034] The utility model aims to provide an embodiment of an energy storage power supply.

[0035] Reference Figure 1 In this embodiment, an energy storage power supply mainly includes an energy storage body 100 and a moving component 190.

[0036] Reference Figure 2 As for the energy storage body 100, the energy storage body 100 includes a casing 110, a lithium battery pack 120 and an inverter 130 arranged in the casing 110, so that the casing 110 can protect the lithium battery pack 120 and the inverter 130, and prevent the lithium battery pack 120 and the inverter 130 from being damaged by collision with external objects.

[0037] Specifically, the housing 110 includes a bottom shell 140, an aluminum alloy bottom plate 150, a middle shell 160 and an upper shell 170 connected in sequence from bottom to top. The lithium battery pack 120 is installed on the aluminum alloy bottom plate 150. The housing 110 is also provided with a plurality of metal screws 180, which pass through the upper shell 170 and the middle shell 160 and are threadedly connected to the aluminum alloy bottom plate 150.

[0038] It can be understood that the lithium battery pack 120 is an energy storage element and is heavy. By providing an aluminum alloy bottom shell 140 to support the lithium battery pack 120, and the bottom shell 140 and the middle shell 160 are both connected to the aluminum alloy bottom plate 150, the casing 110 can use the aluminum alloy bottom plate 150 as a supporting core to ensure the structural strength of the frame. At the same time, by providing a plurality of metal screws 180 on the frame, the metal screws 180 pass through the upper shell 170 and the middle shell 160 and are threadedly connected to the aluminum alloy bottom plate 150, so that the metal screws 180 can tightly connect the upper shell 170, the middle shell 160 and the aluminum alloy bottom plate 150 into one, thereby improving the structural strength of the frame and providing the frame with strong compressive strength, making it convenient for two or more energy storage bodies 100 to be stacked and connected in parallel or for capacity expansion. Therefore, the energy storage power supply can reduce the use of metal shells while ensuring the strength of the core structure, while reducing manufacturing costs and weight while ensuring the strength of the fuselage, making it easy to carry.

[0039] In some specific embodiments, four metal screws 180 are provided, and the four metal screws 180 are respectively distributed at the four corners of the rack, thereby making the position distribution of the metal screws 180 on the rack more balanced.

[0040] In some specific embodiments, the material of the bottom shell 140, the middle shell 160 and the upper shell 170 is set to plastic, thereby making the weight of the housing 110 lighter and, in turn, making the energy storage power supply more convenient to carry.

[0041] In some specific embodiments, a partition 230 is provided inside the middle shell 160, and the partition 230 divides the interior of the middle shell 160 into an upper chamber 240 and a lower chamber 250. The upper chamber 240 accommodates the inverter 130, and the lower chamber 250 accommodates the lithium battery pack 120. Therefore, on the one hand, the partition 230 can separate the lithium battery pack 120 and the inverter 130, so that the heat generated by the lithium battery pack 120 during operation can be isolated by the partition 230, reducing the heat transferred to the inverter 130 and reducing the impact of the heat generated by the lithium battery pack 120 during operation on the inverter 130. On the other hand, the partition 230 can support the inverter 130 to prevent the inverter 130 from crushing the lithium battery pack 120.

[0042] In some specific embodiments, the side wall of the middle shell 160 is provided with a heat dissipation opening 260 that passes through the inside and outside. The heat dissipation opening 260 is covered with a ventilation net 270 , thereby facilitating heat dissipation of the middle shell 160 .

[0043] Furthermore, the heat dissipation vent 260 communicates with the upper cavity 240 and the lower cavity 250 , so that the heat dissipation vent 260 can dissipate heat from both the upper cavity 240 and the lower cavity 250 at the same time.

[0044] In some specific embodiments, a heat dissipation fan 280 is installed inside the ventilation net 270 , so that the heat dissipation fan 280 can actively dissipate heat inside the middle shell 160 , thereby improving the heat dissipation efficiency.

[0045] Furthermore, the cooling fan 280 is located in the lower cavity 250. It can be understood that the lithium battery pack 120 is the main heat source of the energy storage body. The cooling fan 280 is located in the lower cavity 250, so that the cooling fan 280 can be close to the lithium battery pack 120, thereby improving the heat dissipation effect of the cooling fan 280 on the lithium battery pack 120.

[0046] In some specific embodiments, a handle 290 is provided on the top of the upper shell 170, and the metal screw 180 passes through the handle 290. The top of the metal screw 180 is not lower than the top surface of the handle 290, thereby making it convenient for the user to use the handle 290 to carry the energy storage body. At the same time, the metal screw 180 can fix the handle 290, making the handle 290 more secure. In addition, the top of the metal screw 180 is not lower than the top surface of the handle 290, so that the top of the metal screw 180 can abut and support another energy storage body, thereby improving the compressive strength of the energy storage body.

[0047] In some specific embodiments, the lithium battery pack 120 is electrically connected to the inverter 130 , and a function panel is further provided on the housing 110 . The function panel is provided outside the middle housing 160 , and is used to control the operation of the energy storage body 100 .

[0048] Reference Figure 3 As for the mobile component 190, the mobile component 190 includes a bracket 200, a pull rod 210 connecting the bracket 200, and a wheel 220. The wheel 220 is used to support the movement of the bracket 200, and the bracket 200 is used to support the energy storage body 100, thereby facilitating the mobile use of the energy storage power supply at any time.

[0049] In some specific embodiments, a slot 300 is provided at the top of the upper shell 170, and a block 310 is provided at the pull rod 210. The block 310 cooperates with the slot 300 to limit the position, so that the block 310 can limit the top of the casing 110 frontward and back and left and right, thereby preventing the casing 110 from separating from the moving component 190, making the structure of the energy storage power supply more solid and compact.

[0050] Furthermore, the pull rod 210 is provided with a cross beam 320, and the clamping block 310 and the cross beam 320 are detachably connected by bolts, thereby facilitating the disassembly and installation of the energy storage body and the moving assembly 190, thereby making the use of the energy storage body more flexible.

[0051] Reference Figure 4 In some specific embodiments, at least two energy storage bodies 100 are provided, and at least two energy storage bodies 100 are stacked up and down. The top of the metal screw 180 of one energy storage body 100 can support the bottom shell 140 of another adjacent energy storage body 100 above, thereby facilitating the expansion of the energy storage capacitor.
