It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.

[0038] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components.

[0039] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but are in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is less than that of the second feature.

[0040] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] This embodiment provides an energy storage power supply, which includes a battery module and a power supply housing. A receiving cavity for accommodating the battery module is formed in the power supply housing, as Figure 1 and Figure 2 shown. The power supply housing includes a first housing component 10 and a second housing component 20, and the receiving cavity is formed by the mutual snap-fit of the first housing component 10 and the second housing component 20.

[0042] Furthermore, as Figure 2 and Figure 3 shown, a first sliding connector is provided on the first housing component 10, and a second sliding connector is provided on the second housing component 20. Both the first sliding connector and the second sliding connector extend along the vertical direction, and the first sliding connector can be slidably connected to the second sliding connector, so that the first housing component 10 and the second housing component 20 are mutually snap-fitted to form a receiving cavity for accommodating the battery module, and the first housing component 10 is locked to the second housing component 20 to fix the two. Specifically, the lower end of the first housing component 10 is locked to the bottom of the second housing component 20.

[0043] Specifically, the energy storage power supply provided in this embodiment loads the battery module in the power supply housing. During assembly, the battery module is fixed to the second housing component 20, and then the first housing component 10 and the second housing component 20 are buckled with each other through the first sliding connection member and the second sliding connection member. After buckling, the lower end of the first housing component 10 is locked to the bottom of the second housing component 20, and the assembly can be completed. This reduces the usage of screws, improves the assembly efficiency, reduces the labor cost and material cost of assembly, and hides the locking structure at the bottom of the second housing component 20, so that no screws are exposed on the entire power supply housing, improving the aesthetics.

[0044] Exemplarily, as Figures 3 - 10 shown, the first housing component 10 includes a first base shell 11, a first side shell 12 and a second side shell 13. The first side shell 12 and the second side shell 13 are respectively connected to both ends of the first base shell 11 in the first direction, and first sliding connection members are provided on both the first side shell 12 and the second side shell 13. The second housing component 20 includes a second base shell 21 and two side covers 22. The two side covers 22 are respectively connected to both ends of the second base shell 21 in the second direction. The first direction is perpendicular to the second direction, and second sliding connection members are provided on both the two side covers 22. The lower ends of the first side shell 12 and the second side shell 13 are both locked to the second base shell 21. The first direction is the AB direction in the attached drawing, and the second direction is the CD direction in the attached drawing. In this embodiment, the first base shell 11 is the top shell, the first side shell 12 is the front shell, the second side shell 13 is the rear shell, and the first side shell 12 and the second side shell 13 are respectively arranged on the front and rear sides of the first base shell 11; the second base shell 21 is the bottom shell, and the two side covers 22 are respectively arranged on the left and right sides of the second base shell 21.

[0045] In this embodiment, as Figures 2 - 10 shown, first sliding connection members are provided on both sides of the first side shell 12 in the second direction, and first sliding connection members are provided on both sides of the second side shell 13 in the second direction; correspondingly, second sliding connection members are provided on both sides of the two side covers 22 in the first direction. The above four groups of first sliding connection members and second sliding connection members are in one-to-one correspondence and cooperate with each other to realize reliable sliding and buckling between the first housing component 10 and the second housing component 20.

[0046] Exemplarily, a concave-convex matching guide rail and guide groove structure can be adopted between the first sliding connection member and the second sliding connection member. In this embodiment, as Figures 2 - 10As shown, the first sliding connector is the groove seat 30, and the second sliding connector is the guide rail strip 40. The guide rail strip 40 can be inserted into the groove seat 30 in the vertical direction. When the guide rail strip 40 is inserted into the groove seat 30, the groove seat 30 limits the degrees of freedom of the guide rail strip 40 in the groove depth direction and the groove width direction. That is to say, by simply buckling the first housing assembly 10 and the second housing assembly 20 with each other, the degrees of freedom between the two in the horizontal direction can be restricted, ensuring that the power supply housings are locked with each other in the front, rear, left, and right directions. Compared with the one-way limiting assembly method, the stability is better, and the amount of installation screws can be reduced, reducing the labor cost and material cost of assembly.

[0047] Exemplarily, as Figures 4 - 8 shown, a plurality of reinforcing ribs 101 are provided on the inner sides of the first side shell 12 and the second side shell 13. The arrangement of the plurality of reinforcing ribs 101 on the first side shell 12 is the same as that on the second side shell 13. Taking the second side shell 13 as an example, as Figure 8 shown, a plurality of reinforcing ribs 101 are provided on both sides of the second side shell 13 in the second direction. The reinforcing ribs 101 on both sides are arranged at intervals in the vertical direction. The reinforcing ribs 101 extend in the horizontal direction. An avoidance groove 31 is formed between one end of the reinforcing rib 101 and the inner wall of the second side shell 13. The plurality of avoidance grooves 31 arranged at intervals in the vertical direction are combined to form the groove seat 30. The reinforcing ribs 101 in this embodiment can strengthen the structural strength of the first side shell 12 and the second side shell 13, and utilize the reinforcing ribs 101 to form the avoidance grooves 31. The plurality of avoidance grooves 31 are combined to form the groove seat 30. The design is ingenious, and the groove seat 30 is formed together when the reinforcing ribs 101 are formed, simplifying the production process and the mold structure.

[0048] Exemplarily, a limiting flange is provided in the groove seat 30. The limiting flange is provided at the groove opening of the groove seat 30 and is used to limit the degree of freedom of the guide rail strip 40 in the groove depth direction of the groove seat 30. Specifically, the groove seat 30 limits the degree of freedom of the guide rail strip 40 in the groove width direction through the side walls on its left and right sides, and the limiting flange limits the degree of freedom of the guide rail strip 40 in the groove depth direction. The two cooperate to limit the position of the guide rail strip 40 in the horizontal direction.

[0049] Exemplarily, as Figures 4 - 8 shown, the limiting flange includes a plurality of limiting protrusions 32. The limiting protrusions 32 are provided in the groove seat 30. Specifically, a plurality of limiting protrusions 32 are provided on the inner sides of the first side shell 12 and the second side shell 13. The arrangement of the plurality of limiting protrusions 32 on the first side shell 12 is the same as that on the second side shell 13. Taking the second side shell 13 as an example, as Figure 8As shown, a plurality of limiting protrusions 32 are arranged at intervals in the vertical direction on the inner side of the second side shell 13. The limiting protrusions 32 and the avoidance grooves 31 are arranged in an alternating manner. The limiting protrusions 32 are used to limit the freedom degree of the guide rail strip 40 in the groove depth direction of the groove seat 30. The alternating arrangement between the limiting protrusions 32 and the avoidance grooves 31 can reduce the forming difficulty of the two and simplify the die structure.

[0050] Exemplarily, as Figure 10 shown, the guide rail strip 40 includes a connecting portion 41, a first limiting portion 42, and a second limiting portion 43. One end of the connecting portion 41 is connected to the second housing assembly 20. The first limiting portion 42 and the second limiting portion 43 are arranged at intervals at the other end of the connecting portion 41. The first limiting portion 42 is disposed opposite to the bottom of the groove seat 30, and the second limiting portion 43 is disposed opposite to the inner side surface of the limiting flange. Specifically, both the first limiting portion 42 and the second limiting portion 43 are perpendicular to the connecting portion 41, and both ends of the first limiting portion 42 and the second limiting portion 43 extend toward both sides of the connecting portion 41. The two ends of the first limiting portion 42 and the second limiting portion 43 are respectively used to abut against the left and right side walls of the groove seat 30. The side surface of the first limiting portion 42 facing away from the second housing assembly 20 is used to abut against the bottom of the groove seat 30, and the side surface of the second limiting portion 43 facing the second housing assembly 20 is used to abut against the inner side surface of the limiting flange.

[0051] Exemplarily, as Figures 3 - 8 shown, both sides of the first side shell 12 and the second side shell 13 in the second direction are bent toward the side cover 22. On the one hand, it is convenient for the cooperation between the groove seat 30 and the guide rail strip 40, avoiding the sliding and buckling structures being arranged at the corners, reducing the requirement for processing accuracy and the processing difficulty. On the other hand, a rounded corner structure is formed at the corner to improve the aesthetics.
