Each side end plate 420 is provided with a second screw hole 428. The mounting frame 200 is provided with at least two screw holes 201. Each locking member 470 is screwed into the second screw hole 428 through the corresponding screw hole 201, allowing the mounting frame 200 to be detachably connected to the two side end plates 420, thereby reliably supporting and fixing the two side end plates 420 to the mounting frame 200. In this embodiment, a second reverse rivet nut 4203 is protruding from the side of each side end plate 420 facing away from the mounting frame 200. The second screw hole 428 is defined in the second reverse rivet nut 4203, allowing each locking member 470 to be reliably screwed into the second screw hole through the corresponding screw hole 201. It is understood that in other embodiments, the second reverse rivet nut 4203 is not required, and the second screw hole is directly defined on the side end plate 420. Specifically, each locking member 470 is a screw or a bolt. And / or,

[0066] like Figure 9 、 Figure 10 and Figure 11As shown, in one embodiment, a limiting fold 4252 is protruded from the support portion 425 of each side end plate 420, and the mounting frame 200 is provided with at least two limiting holes 203.

In this embodiment, the mounting frame 200 is provided with at least one limiting hole 203 at each end in the longitudinal direction, so that the mounting frame 200 is reliably positioned and assembled with the two side end plates 420 along the longitudinal direction.

In this embodiment, the first bending baffle 202, the second bending baffle 204 and the mounting frame 200 are an integrally stamped structure, so that the first bending baffle 202, the second bending baffle 204 and the mounting frame 200 are reliably connected, while reducing the number of components of the energy storage power supply 10, even making the structure of the energy storage power supply 10 more compact.

[0068] like Figure 4 、 Figure 5 and Figure 12 As shown, further, positioning grooves 206 are respectively provided on both end sides of the mounting frame 200, and a positioning boss 441 is protruded from the top of each insulating plate 440, so that the positioning boss 441 of each insulating plate 440 is located in the corresponding positioning groove 206, thereby realizing rapid positioning and assembly of the mounting frame 200.

The first fixing column 210 is supported and fixed to the BMS board 310, and the inverter insulation gasket 350 is provided with an insulating through-hole 331. The second fixing column 220 is supported and fixed to the inverter module 320 through the insulating through-hole, so that the inverter module 320 and the BMS board 310 are relatively insulated and installed on the mounting frame 200.

The inverter insulation gasket 350 is provided with a connecting through-hole 351 and a avoiding through-hole 352. The second fixing member 330 is passed through the connecting through-hole 351, so that the second fixing member 330 is screwed into the second threaded hole 222 through the positioning hole 322. The support column 340 is also electrically connected to the inverter module 320 through the avoiding through-hole 352, so that the BMS board 310 is electrically connected to the inverter module 320, and at the same time, a predetermined height exists between the inverter insulation gasket 350. In this embodiment, the support column 340 includes an insulating sleeve 341 and a nut column 343. The insulating sleeve 341 is sleeved on the nut column 343.

The BMS board 310 has a first conductive hole 313, and the inverter module 320 has a second conductive hole (not shown). The two ends of the nut column 343 are respectively located in the first conductive hole 313 and the second conductive hole, so that the nut column 343 is electrically connected to the BMS board 310 and the inverter module 320 respectively.

[0075] like Figure 5 、 Figure 6 、 Figure 12 、 Figure 13 and Figure 14As shown, further, the horizontal module 410 also includes a positive connecting aluminum sheet 416 and a negative connecting aluminum sheet 417, and the positive connecting aluminum sheet 416 and the negative connecting aluminum sheet 417 are both arranged on the first side bracket 414a; the number of battery cells 412 is multiple, and the multiple battery cells 412 are arranged side by side, and the two ends of each battery cell 412 are respectively embedded in the two side brackets 414, and the positive poles of the multiple battery cells 412 are all electrically connected to the positive connecting aluminum sheet 416, and the negative poles of the multiple battery cells 412 are all electrically connected to the negative connecting aluminum sheet 417; the positive connecting aluminum sheet 416 and the negative connecting aluminum sheet 417 are both electrically connected to the BMS board 310. In this embodiment, the positive connecting aluminum sheet 416 and the negative connecting aluminum sheet 417 are both aluminum sheets, replacing the nickel sheets of the prior art, which is relatively low in cost. The battery module structure 400 is fixed by two side end plates 420 and screw members 430. Each side end plate 420 is fixedly connected to the bottom shell 110, and the overall assembly structure is relatively simple and lightweight. Furthermore, the BMS board 310 is provided with a positive reverse rivet terminal 314 and a negative reverse rivet terminal 315.

Specifically, the locking member is a bolt or a screw.

[0077] like Figure 2 and Figure 3 As shown, further, the connection position between the fixing portion 421 and the bottom shell 110 is adjustable, so that the distance between the two side end plates 420 can be adjusted, thereby enabling the two side end plates 420 to adapt to horizontal modules 410 of different sizes. In this embodiment, the fixing through-hole 4213 is a waist-shaped hole, so that the connection position between the fixing portion 421 and the bottom shell 110 is adjustable.

[0078] Compared with the prior art, the present disclosure has at least the following advantages:

[0079] 1) The battery module structure 400 includes a horizontal module 410, two side brackets 414 arranged opposite to each other, and the two ends of the battery cell 412 are respectively embedded in the two side brackets 414, so that the horizontal module 410 can be placed horizontally in the housing 100; during assembly, the first side end plate 420a is located on the side of the first side end plate 420a away from the second side end plate 420b, and the second side end plate 420b is located on the side of the second side end plate 420b away from the first side end plate 420a, and the screw member 430 is sequentially penetrated through the first side end plate 420a. The third through hole 4232 of the locking portion 423 of the first side end plate 420a, the first through hole 4142, the second through hole 4144, and the third through hole 4232 of the locking portion 423 of the second side end plate 420b are used to sequentially lock and assemble the first side end plate 420a, the first side bracket 414a, the second side bracket 414b, and the second side end plate 420b using the screw member 430. This secures the battery cell 412 between the two side brackets 414, significantly reducing the height of the battery module and facilitating the development of a low-profile design for the energy storage power supply 10.

[0080] 2) Since each side end plate 420 includes a fixing portion 421, a locking portion 423 and a supporting portion 425 connected in sequence, the fixing portion 421 is connected to the bottom shell 110, and the locking portions 423 of the two side end plates 420 respectively abut against the side of the corresponding side bracket 414 away from the battery cell 412, that is, the locking portions 423 of the two side end plates 420 respectively abut against the two sides of the horizontal module 410, and the supporting portions 425 of the two side end plates 420 are jointly supported on the mounting frame 200, so that the mounting frame 200 is located above the horizontal module 410, and there is a ventilation gap between the mounting frame 200 and the horizontal module 410, which is conducive to ventilation and heat dissipation of the battery module, that is, the ventilation and heat dissipation effect of the battery module is improved.

[0081] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
