[0023] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments: like Figures 1 to 5 As shown, an energy storage power supply 10 of an embodiment includes a battery pack 100 and a fixing assembly 200, and the fixing assembly 200 is used to accommodate and fix the battery pack 100; in one embodiment, the fixing assembly 200 includes a base 210, a fixing column 220 and a lower pressure frame 230, the base 210 is provided with a fixing area 212, the fixing column 220 is fixedly connected to the base 210, the lower pressure frame 230 is connected to the fixing column 220, and the lower pressure frame 230 is arranged opposite to the fixing area 212.

[0024] Furthermore, the connection position between the lower press frame 230 and the fixing column 220 is adjustable, so that the distance between the lower press frame 230 and the fixing area 212 is adjustable, and then the lower press frame 230 adjusts the distance between the lower press frame 230 and the fixing area 212 according to the height dimension of the battery pack 100, so that the fixing assembly 200 can be compatible with battery packs 100 of different height dimensions. In one embodiment, the fixing assembly 200 is provided with a reference plane, and the reference plane is parallel to the horizontal plane. The distance between the lower press frame 230 and the reference plane is the adaptation distance.

[0025] The above-mentioned fixing assembly 200 and energy storage power supply 10, since the lower pressure frame 230 is connected to the fixing column 220, the lower pressure frame 230 and the fixing area 212 are arranged opposite to each other, and the connection position of the lower pressure frame 230 and the fixing column 220 is adjustable, so that the distance between the lower pressure frame 230 and the fixing area 212 is adjustable, and the adapter bracket 240 can be selectively installed on the fixing area 212, so that the fixing assembly 200 can adapt to the installation of battery packs 100 of different models, thereby improving the compatibility of the shell of the energy storage power supply 10.

[0026] like Figures 1 to 5As shown, further, the battery pack 100 is a first battery pack 100a or a second battery pack 100b. In this embodiment, the battery pack 100 is divided into a first battery pack 100a and a second battery pack 100b according to the shape, so that the fixing component 200 can be compatible with at least two shapes of battery packs 100. It can be understood that for the first battery pack 100a, according to the size of the battery pack 100, such as the height of the battery pack 100, the type of the first battery pack 100a can be a first battery pack 100a of multiple specifications. Similarly, for the second battery pack 100b, according to the size of the battery pack 100, such as the height of the battery pack 100, the type of the second battery pack 100b can be a second battery pack 100b of multiple specifications. In this way, according to different combinations of shapes and specifications, the fixing component 200 can be compatible with and accommodate and fix multiple types of battery packs 100.

[0027] like Figures 1 to 4 As shown, in order to make the connection between the battery pack 100 and the base 210 more secure, in one embodiment, the fixing assembly further includes a screw column 400, and the lower pressing frame 230 is provided with a positioning hole 232, and the screw column 400 is detachably connected to the fixing area 212 through the positioning hole 232 and the limiting hole 102 of the battery pack, respectively, so that the connection between the battery pack 100 and the base 210 is more secure. In this embodiment, the battery pack 100 is provided with a limiting hole 102, and the screw column 400 is detachably connected to the fixing area 212 through the positioning hole 232 and the limiting hole 102, respectively, so that the connection between the battery pack 100 and the base 210 is more secure. Specifically, the battery pack is a first battery pack 100a.

[0028] Furthermore, the base 210 is provided with a mounting screw hole 213, and the screw column 400 is screwed into the mounting screw hole 213 through the positioning hole 232 and the limiting hole 102 respectively, so that the screw column 400 is detachably connected to the fixing area 212 through the positioning hole 232 and the limiting hole 102 respectively.

[0029] like Figures 5 to 7 As shown, in another embodiment, the fixing assembly 200 further includes an adapter bracket 240, and the adapter bracket 240 is detachably connected to the fixing area 212, and the adapter bracket 240 is arranged opposite to the lower pressure frame 230, so that the battery pack is fixed between the lower pressure frame and the adapter bracket. In this embodiment, the adapter bracket 240 is installed on the fixing area 212, the lower pressure frame 230 is connected to the fixing column 220, and the battery pack is fixed between the lower pressure frame 230 and the adapter bracket 240, so that the upper end of the battery pack abuts against the lower pressure frame 230, and the lower end of the battery pack abuts against the adapter bracket 240. Specifically, the battery pack is the second battery pack 100b.

[0030] Since the adapter bracket 240 is detachably connected to the fixed area 212, when installing different types of battery packs 100, the adapter bracket 240 can be selectively installed on the fixed area 212 to be compatible with at least two different types of battery packs 100, thereby reducing the design of the base 210 of a specific model, and then reducing the design of the outer shell manufacturing mold, thereby improving the compatibility of the outer shell of the energy storage power supply 10; the adapter bracket 240 is installed on the fixed area 212, the lower pressure frame 230 is connected to the fixed column 220, and the battery pack is fixed between the lower pressure frame 230 and the adapter bracket 240, so that the adapter bracket 240 can be selectively removed or installed in the fixed area 212, that is, the adapter bracket 240 can be selectively installed on the fixed area 212. Since the lower pressure frame 230 is connected to the fixing column 220, the lower pressure frame 230 and the fixing area 212 are arranged opposite to each other, and the connection position between the lower pressure frame 230 and the fixing column 220 is adjustable, the distance between the lower pressure frame 230 and the fixing area 212 is adjustable, and the adapter bracket 240 can be selectively installed on the fixing area 212, so that the fixing assembly 200 can adapt to the installation of more types of battery packs 100, further improving the compatibility of the shell of the energy storage power supply 10.

[0031] In one embodiment, when in use, the adapter bracket 240 is installed or removed from the fixed area 212 as needed. Through the clever design of the adapter bracket 240, the design of the base 210 of a specific model is reduced, thereby reducing the design style of the shell manufacturing mold, improving the compatibility of the fixing assembly 200, and thereby improving the compatibility of the shell of the energy storage power supply 10. When the adapter bracket 240 is installed, the reference plane is the surface where the adapter bracket 240 abuts against the bottom surface of the battery pack 100. When the adapter bracket 240 is not installed, the reference plane is the surface where the inner wall of the base 210 abuts against the bottom surface of the battery pack 100.

[0032] like Figure 1 , Figures 5 to 7 As shown, in one embodiment, the fixing assembly 200 further includes a mounting member 300 , and the adapter bracket 240 is detachably connected to the fixing area 212 via the mounting member 300 , so that the adapter bracket 240 is detachably connected to the fixing area 212 .

[0033] like Figure 1 , Figures 5 to 8 , Fig.12 As shown, further, the base 210 is provided with a mounting screw hole 213, the adapter bracket 240 is provided with a mounting through hole 242, and the mounting member 300 is screwed into the mounting screw hole 213 through the mounting through hole 242, so that the adapter bracket 240 is detachably connected to the fixing area 212. In this embodiment, the mounting member 300 is a screw or a stud.

[0034] In one embodiment, the mounting screw hole 213 is not only adapted to the screw connection assembly of the screw column 400, but also adapted to the screw connection assembly of the mounting member 300, thereby improving the compatibility of the mounting screw hole, realizing the switching installation requirements of the first battery pack 100a and the second battery pack 100b, and making the structure of the base 210 more compact and having higher structural strength. In other embodiments, the position where the positioning area is screwed to the screw column 400 and the mounting screw hole 213 can also be staggered, that is, the position where the positioning area is screwed to the screw column 400 and the mounting screw hole 213 are not the same screw hole.

[0035] See also Figure 6 Furthermore, the mounting holes 242 are waist-shaped holes, and the extending direction of the mounting holes 242 is parallel to the length or width direction of the adapter bracket 240, so that the connection position between the adapter bracket 240 and the fixing area 212 is adjustable, thereby improving the compatibility of the adapter bracket 240. Furthermore, there are multiple mounting holes 242, and the mounting member 300 is screwed into the mounting screw hole 213 through one of the mounting holes 242, thereby improving the flexibility of the fixed connection between the adapter bracket 240 and the fixing area 212.

[0036] It can be understood that in other embodiments, the mounting member 300 can be omitted, and the adapter bracket 240 is not limited to being detachably connected to the fixing area 212 through the mounting member 300. For example, the adapter bracket 240 is snap-connected to the fixing area 212. Specifically, the fixing area 212 is provided with a snap groove, and the adapter bracket 240 is formed with a snap, and the snap is snapped into the snap groove, so that the adapter bracket 240 is snap-connected to the fixing area 212.

[0037] like Figures 4 to 6 As shown, in one embodiment, the adapter bracket 240 is also used to be detachably connected to the battery pack 100 when installed in the fixing area 212. When the adapter bracket 240 is fixed to the fixing area 212, the adapter bracket 240 is also fixedly connected to the battery pack 100, so that the battery pack 100 is better fixedly connected to the fixing area 212 through the adapter bracket 240. See also Figures 8 to 10 In this embodiment, the fixing assembly 200 further includes a locking member 250, the adapter bracket 240 is provided with a connecting through hole 244, the battery pack 100 is provided with a locking hole 106, and the locking member 250 is screwed into the locking hole 106 through the connecting through hole 244, so that the adapter bracket 240 can be detachably connected to the battery pack 100. Specifically, the locking member 250 is a screw or a stud.

[0038] like Figures 4 to 5As shown, in one embodiment, the adapter bracket 240 includes a positioning support portion 240a and a fixing portion 240b that are connected to each other, and an angle exists between an extension direction of the positioning support portion 240a and an extension direction of the fixing portion 240b; the positioning support portion 240a is detachably connected to the fixing area 212, and the fixing portion 240b is used to be detachably connected to the battery pack 100, so that the fixing portion 240b and the positioning support portion 240a can be fixedly connected to the fixing area 212 and the battery pack 100 in two directions, respectively, thereby improving the convenience and reliability of installing the battery pack 100 on the fixing assembly 200. In this embodiment, the angle is 90°, that is, the extension direction of the positioning support portion 240a and the extension direction of the fixing portion 240b are perpendicular to each other, so that the fixing portion 240b can better limit and fix the side wall of the battery pack 100 when the positioning support portion 240a is connected to the bottom of the battery pack 100, so as to prevent the battery pack 100 from shifting relative to the positioning support portion 240a, so that the battery pack 100 can be more conveniently and reliably installed on the fixing assembly 200. It can be understood that in other embodiments, the angle is not limited to 90°, for example, the angle can be 70° or 80°, etc.

[0039] like Figure 1 , Figures 5 to 9As shown, further, a plurality of positioning ribs are protruding from the base 210, namely a first positioning rib 213, a second positioning rib 215, a third positioning rib 217 and a fourth positioning rib 219. The first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 together form a fixed area 212, so that each first positioning rib 213 and each second positioning rib 215 are in contact with the outer wall of the battery pack 100. In this embodiment, the first positioning rib 213 and the second positioning rib 215 are arranged opposite to each other along the length direction of the base 210, the third positioning rib 217 and the fourth positioning rib 219 are arranged opposite to each other along the length direction of the base 210 (i.e. parallel to the X-axis direction), the first positioning rib 213 and the third positioning rib 217 are arranged opposite to each other along the width direction of the base 210 (i.e. parallel to the Y-axis direction), and the second positioning rib 215 and the fourth positioning rib 219 are arranged opposite to each other along the width direction of the base 210 so that the first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 are all in contact with the outer wall of the battery pack 100. In this embodiment, when the adapter bracket 240 is disassembled from the fixing area 212, the first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 are all in contact with the outer wall of the battery pack 100. Furthermore, when the adapter bracket 240 is installed in the fixing area 212, the first positioning rib 213 and the third positioning rib 217 abut against the first end side of the adapter bracket 240 side by side, and the second positioning rib 215 and the fourth positioning rib 219 abut against the second end side of the adapter bracket 240 side by side, so that the adapter bracket 240 is quickly fixed and positioned in the fixing area 212. In this embodiment, two first lateral slots 2402 are provided on the first end side of the adapter bracket 240, and the first positioning rib 213 and the third positioning rib 217 are respectively abutted against the two first lateral slots 2402; two second lateral slots 2404 are provided on the second end side of the adapter bracket 240, and the second positioning rib 215 and the fourth positioning rib 219 are abutted against the two second lateral slots 2404 side by side, so that the first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 are better abutted against the two end sides of the adapter bracket 240.

[0040] like Figure 1As shown, further, the first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 are all integrally formed on the base 210, so that the first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 are all reliably fixed on the base 210, and the structure of the base 210 is more compact. It can be understood that in other embodiments, the first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 are not limited to being integrally formed on the base 210. For example, the base 210, the first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 are all individually formed, and the first positioning rib 213, the second positioning rib 215, the third positioning rib 217 and the fourth positioning rib 219 are all glued or welded on the base 210.

[0041] like Figure 1 , Figure 7 , Fig. 9 and Fig.11 As shown, further, the support surface where the fixing area 212 is located is a mesh groove structure surface, that is, the support surface where the fixing area 212 is located is provided with a plurality of mesh grooves 2122, and the plurality of mesh grooves are sequentially connected to form a mesh groove structure surface, thereby improving the structural strength of the base 210 and reducing the weight of the base 210. Further, at least n continuous mesh grooves 2122 form a wind-passing mesh belt 2124, wherein n is an integer; the wind-passing mesh belt 2124 is arranged between the first positioning rib 213 and the second positioning rib 215; and / or, the wind-passing mesh belt 2124 is arranged between the second positioning rib 215 and the third positioning rib 217; and / or, the wind-passing mesh belt 2124 is arranged between the third positioning rib 217 and the fourth positioning rib 219; and / or, the wind-passing mesh belt 2124 is arranged between the fourth positioning rib 219 and the first positioning rib 213, thereby improving the heat dissipation effect of the bottom of the battery pack.

[0042] Furthermore, the height of each grid slot constituting the wind-passing grid belt is a first wind-passing height, and the height of the grid slot connected to each positioning rib is a second wind-passing height. The first wind-passing height is lower than the second wind-passing height, so that there is a flow gap between the wind-passing grid belt and the battery pack or the adapter bracket. In this way, the air flow on the two end surfaces of the battery pack is convected through the flow gap, thereby improving the heat dissipation performance of the energy storage power supply.

[0043] like Figure 1 , Figure 8 , Fig. 9 and Fig.12As shown, further, the mounting screw hole 213 is opened in the fixing area 212, so that the adapter bracket 240 is detachably connected to the fixing area 212 through the mounting member 300, and then the battery pack 100 is reliably fixedly connected to the fixing area 212 through the adapter bracket 240. In this embodiment, the base 210 is provided with a fixing platform 260 in the fixing area 212, and the mounting screw hole 213 is opened in the fixing platform 260, and the outer peripheral wall of the fixing platform 260 is connected to the mesh groove structure surface. In this embodiment, the height of the fixing platform 260 is equal to the second wind-passing height, so that the air flow parallel to the Y-axis direction at the two end faces of the battery pack is convenient for convection, thereby improving the heat dissipation performance of the energy storage power supply. Furthermore, the height of the grid groove connected to the positioning rib and the height of the fixing column are both equal to the second wind-passing height, and the wind-passing grid belt is passed between the fixing column and the positioning rib adjacent to the fixing column, so that the air flow parallel to the Y-axis direction at the two end faces of the battery pack is convenient for convection, thereby further improving the heat dissipation performance of the energy storage power supply.

[0044] like Figure 1 and Fig.12 As shown, further, the fixed platform 260 includes a retaining ring 262, a fixed column body 264 and a plurality of connecting ribs 266. The retaining ring 262 and the fixed column body 264 are both connected to the base 210. The retaining ring 262 is arranged around the fixed column body 264, and a connecting gap 263 is formed between the retaining ring 262 and the fixed column body 264. A plurality of connecting ribs 266 are located in the connecting gap 263. The plurality of connecting ribs 266 are distributed at intervals along the circumference of the fixed column body 264, and each connecting rib 266 is connected to the base 210, the outer peripheral wall of the fixed column body 264 and the inner peripheral wall of the retaining ring 262, so that the fixed platform 260 is firmly connected to the base 210, and at the same time, the weight of the fixed platform 260 is reduced, and the structural strength of the fixed platform 260 is increased under the same material conditions. The outer peripheral wall of the retaining ring 262 is connected to the mesh groove structural surface.

[0045] like Figure 6 As shown, in one embodiment, the positioning support portion 240a and the fixing portion 240b are an integral stamping structure, so that the structure of the adapter bracket 240 is more compact and the adapter bracket 240 has better structural strength. In this embodiment, the adapter bracket 240 is a metal stamping bracket. In other embodiments, the positioning support portion 240a and the fixing portion 240b are separately formed and welded together.

[0046] like Figure 6As shown, further, the second battery pack 100b includes a battery pack main body 110 and a corrugated rib structure plate 120 fixed to the outside of the battery pack main body 110, and the corrugated rib structure plate 120 is formed with a plurality of heat dissipation through grooves 122 spaced apart along the length direction, and both ends of each heat dissipation through groove 122 extend to both ends of the width direction of the corrugated rib structure plate 120, respectively, so that the air flow on both sides of the battery pack main body 110 can be interactively dissipated through any heat dissipation through groove 122, thereby improving the heat dissipation performance of the battery pack main body 110 and being beneficial to air circulation and heat dissipation. Compared with the flat plate structure, the corrugated rib structure plate 120 disclosed in the present invention has a larger air heat exchange area, thereby improving the thermal management effect of the battery pack 100, and under the premise of the same amount of plastic used, the structural strength of the corrugated rib structure plate 120 disclosed in the present invention is better.
