[0042] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0043] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0046] like Figures 1-10 As shown, this embodiment provides an energy storage power supply, which includes a battery module and a power supply shell. The power supply shell includes a base shell assembly and multiple side blocks. An inner cavity is provided in the base shell assembly, and the battery module is installed in the inner cavity. Multiple windows are provided on the side wall of the base shell assembly, and the side blocks cover the windows one by one.

[0047] Further, such as Figures 1-10 As shown, slots 1 are formed at two opposing side edges of the window. The two side edges of the side block are inserted into the two slots 1 in a one-to-one correspondence. The side edge of the side block includes an inserting portion 8 and a reinforcing portion 3. The inserting portion 8 is inserted into the slot 1, and the reinforcing portion 3 is provided at the edge of the side edge that passes through the slot 1. The thickness of the reinforcing portion 3 is greater than the thickness of the inserting portion 8 and the width of the slot 1. Therefore, the reinforcing portion 3 cannot pass through the slot 1 laterally and cause the side edge of the side block to be separated from the slot 1. A stopper 2 is protruded from one side of the base shell assembly. The stopper 2 is spaced apart from the inner side wall of the base shell assembly to form the slot 1.

[0048] Specifically, the energy storage power supply provided in this embodiment loads the battery module through the power supply shell, and the base shell component of the power supply shell is plugged into and matched with the side block. A slot 1 is provided on the base shell component, and the slot 1 is formed by the limiting portion 2 and the side wall spacing inside the base shell component. The side edge of the side block is provided with a plug-in portion 8 and a reinforcement portion 3. On the one hand, the plug-in portion 8 is plugged into the slot 1 to reduce the shaking of the side block in the groove width direction. On the other hand, the limiting portions 2 on both sides of the window respectively limit the positions of the two reinforcement portions 3 in the horizontal direction to reduce the shaking of the side block in the groove depth direction, thereby limiting the movement and swaying of the side block perpendicular to the plug-in direction, thereby improving the stability of the assembly. In addition, the setting of the reinforcement portion 3 increases the edge thickness of the side block, improves the connection strength between the side block and the base shell component, and reduces the deformation of the product.

[0049] Exemplarily, the window includes a first window and two second windows, wherein the first window is arranged on the front of the base shell assembly, and the two second windows are respectively arranged on the left and right sides of the base shell assembly, and the side block includes a panel 300 and two ventilation side covers 400, the panel 300 covers the first window, and the ventilation side cover 400 covers the second window, and the ventilation side cover 400 is provided with a ventilation louver structure connecting the inside and outside of the power supply shell.

[0050] For example, Figure 1 and Figure 2 As shown, the base shell assembly includes a first base shell 100 and a second base shell 200. Specifically, the first base shell 100 is an upper shell, and the second base shell 200 is a lower shell. The first base shell 100 is provided with a first notch 101, and the second base shell 200 is provided with a second notch 201. The first base shell 100 and the second base shell 200 are buckled up and down, so that the first base shell 100 and the second base shell 200 are surrounded to form a window.

[0051] For example, Figure 4 As shown, the reinforcing portion 3 is arranged opposite to the limiting portion 2, and the thickness of the reinforcing portion 3 gradually increases along the direction close to the side edge. When the operator inserts the left and right side edges of the side stop into the slots 1 on both sides, the thickness of the reinforcing portion 3 is the smallest near the slot 1. As the distance from the slot 1 gradually increases, the thickness of the reinforcing portion 3 gradually increases. This setting provides ample avoidance space between the limiting portion 2 and the reinforcing portion 3, which can avoid mutual interference during insertion due to processing errors of the limiting portion 2, the side edge of the side stop or the reinforcing portion 3, thereby ensuring that the plug-in assembly can proceed smoothly.

[0052] In this embodiment, if Figure 4As shown, a relief slope 31 is provided on the side of the reinforcement portion 3 facing the limiting portion 2. Along the protruding direction of the reinforcement portion 3, the relief slope 31 gradually moves away from the limiting portion 2. When the thickness of the reinforcement portion 3 reaches a maximum, the reinforcement portion 3 forms a step structure, the thickness of the reinforcement portion 3 no longer increases, and its cross-section is trapezoidal. In addition to improving the fault tolerance of assembly, the relief slope 31 also has a guiding function during plugging, which is beneficial to improving the efficiency of assembly. Exemplarily, the inclination angle of the relief slope 31 is 10° to 45°. In other embodiments, the side of the reinforcement portion 3 facing the limiting portion 2 can also be set to a curved surface structure, which can also achieve the effect of gradually changing the thickness of the reinforcement portion 3.

[0053] In this embodiment, if Figure 8 As shown, the reinforcement portion 3 is configured as a strip-shaped structure extending in the same direction as the side stopper's insertion direction. That is, the reinforcement portion 3 is a continuous rib structure, which can significantly improve the edge strength of the side stopper. In other embodiments of the present invention, the reinforcement portion 3 can also be composed of multiple boss structures spaced apart along the insertion direction, which can also provide the effect of limiting and improving structural strength.

[0054] For example, Figure 3-Figure 8 As shown, the slot 1 includes a first slot section 11 and a second slot section 12. The first slot section 11 is formed in the first base shell 100, and the second slot section 12 is formed in the second base shell 200. When the first base shell 100 and the second base shell 200 are interlocked, the first slot section 11 and the second slot section 12 extend along the same straight line. The first slot section 11 and the second slot section 12 are assembled to form a complete slot 1. During assembly, the operator inserts the panel 300 and the two ventilation side covers 400 into the second slot sections 12 on their corresponding second base shell 200, and then interlocks the first base shell 100 with the second base shell 200, the panel 300, and the two ventilation side covers 400 from above, so that the left and right side edges of the panel 300 and the two ventilation side covers 400 are correspondingly inserted into the first slot section 11. This facilitates assembly, reduces the amount of screws used, improves assembly efficiency, eliminates product processing errors, reduces mold thin steel, increases mold strength, and improves mold life.

[0055] For example, Figure 3-Figure 8 As shown, a plurality of first connecting posts 102 are provided within the first base shell 100, and a plurality of second connecting posts 202 are correspondingly provided on the second base shell 200. The first connecting posts 102 and the second connecting posts 202 are connected in a one-to-one correspondence to lock the first base shell 100 to the second base shell 200. Specifically, threaded holes are provided on the first connecting posts 102, and escape holes are provided on the second connecting posts 202 that pass through the first connecting posts 102 and the second base shell 200. Fastening screws are provided through the escape holes and threadably engage with the threaded holes, thereby locking the first connecting posts 102 and the second connecting posts 202, and limiting and securing the battery modules within the base shell assembly.

[0056] For example, Figure 3-Figure 8 As shown, the inner wall of the first base shell 100 and the side wall of the first connecting column 102 enclose a first accommodating space 104, which can accommodate the reinforcement portion 3. A first limiting section 21 is provided on the side wall of the first connecting column 102, and the inner wall of the first base shell 100 and the first limiting section 21 are spaced apart to form a first groove section 11. The inner wall of the second base shell 200 and the side wall of the second connecting column 202 enclose a second accommodating space 204, which can accommodate the reinforcement portion 3. A second limiting section 22 is provided on the side wall of the second connecting column 202, and the inner wall of the second base shell 200 and the second limiting section 22 are spaced apart to form a second groove section 12. When the first base shell 100 and the second base shell 200 are interlocked, the first limiting section 21 and the second limiting section 22 extend along the same straight line, and together they constitute the limiting portion 2. By rationally arranging the positions of the first connecting column 102 and the second connecting column 202, part of the first connecting column 102 and the second connecting column 202 are arranged near the edge of the window, and the first connecting column 102 and the second connecting column 202 are cleverly utilized as the structure for forming the slot 1. One structure plays two roles at the same time, making the structure of the base shell assembly more compact.

[0057] For example, Figure 4 and Figure 6 As shown, a first limiting rib 103 is protruded from the inner wall of the first base shell 100. The first limiting rib 103 extends in the same direction as the first slot section 11. The first limiting rib 103 and the first limiting section 21 are spaced apart to form the first slot section 11. Specifically, the first limiting rib 103 can, on the one hand, limit the position and width of the first slot section 11. During the production of the first base shell 100, the manufacturer can adjust the protruding height of the first limiting rib 103 according to assembly requirements, which provides greater flexibility and makes it easier to control the width dimensional error of the first slot section 11. On the other hand, the provision of the first limiting rib 103 prevents the side stopper from directly pressing against the inner wall of the first base shell 100, further improving the structural strength and assembly stability.

[0058] For example, Figure 8 As shown, a second limiting rib 203 is protruded from the inner wall of the second base shell 200. The second limiting rib 203 extends in the same direction as the second slot segment 12. The second limiting rib 203 and the second limiting segment 22 are spaced apart to form the second slot segment 12. Specifically, the second limiting rib 203 can, on the one hand, limit the position and width of the second slot segment 12. During the production of the second base shell 200, the manufacturer can adjust the protruding height of the second limiting rib 203 according to assembly requirements, which provides greater flexibility and makes it easier to control the width dimensional error of the second slot segment 12. On the other hand, the provision of the second limiting rib 203 prevents the side stopper from directly pressing against the inner wall of the second base shell 200, further improving the structural strength and assembly stability.

[0059] For example, Figure 9 and Figure 10 As shown, the other two side edges of the base shell assembly corresponding to the window (i.e., the upper side edge 7 and the lower side edge 6) are respectively provided with multiple first abutment ribs 4, and the first abutment rib 4 is provided with a first plug-in interface 41 at one end close to the window. The other two side edges of the side block are respectively plugged into the first plug-in interface 41 to assist in positioning and installing the side block.

[0060] Further, such as Figure 9 and Figure 10 As shown, at least one of the other two side edges of the base shell assembly corresponding to the window is provided with a second abutting rib 5, and at least one of the other two side edges of the side stop is provided with a second insertion port 61, and the second abutting rib 5 is inserted into the second insertion port 61. In this embodiment, the second base shell 200 is provided with a second abutting rib 5, and the lower side edge 6 of the side stop is provided with a second insertion port 61, and the second abutting rib 5 is inserted into the second insertion port 61, to help limit the left and right movement of the side stop, further improving assembly reliability.

[0061] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
