[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0039] To address the problem that existing sliding rail brackets typically use limiting blocks to limit the battery packs, resulting in large gaps between battery packs and poor installation stability, this utility model provides an energy storage cabinet.

[0040] like Figures 1 to 14 As shown, the energy storage cabinet is used to house multiple battery packs 1. The energy storage cabinet includes a cabinet body 10 and a supporting guide rail 20. The cabinet body 10 has a battery compartment 11 for accommodating the battery packs 1. The supporting guide rail 20 is disposed inside the battery compartment 11, and the battery packs 1 are slidably connected to the supporting guide rail 20. The tail end of the supporting guide rail 20 is provided with a first positioning structure, and the tail end of the battery packs 1 is provided with a second positioning structure for positioning and cooperating with the first positioning structure. And / or, the head end of the supporting guide rail 20 is provided with a first limiting structure, and the head end of the battery packs 1 is provided with a second limiting structure for cooperating with the first limiting structure.

[0041] In one embodiment of this application, a first positioning structure is provided at the tail of the support guide slide rail 20, and a second positioning structure is provided at the tail of the battery pack 1 for positioning and cooperating with the first positioning structure. This allows the battery pack 1 to achieve positioning connection with the support guide slide rail 20 through the cooperation of the second positioning structure and the first positioning structure, ensuring the positioning reliability of the battery pack 1 and thus ensuring the installation stability of the battery pack 1.

[0042] In another embodiment of this application, a first positioning structure is provided at the tail of the supporting guide slide rail 20, and a second positioning structure is provided at the tail of the battery pack 1 for positioning and cooperating with the first positioning structure; and a first limiting structure is provided at the head of the supporting guide slide rail 20, and a second limiting structure is provided at the head of the battery pack 1 for cooperating with the first limiting structure, so that the battery pack 1 achieves positioning and limiting connection with the supporting guide slide rail 20 through the cooperation of the second positioning structure and the first positioning structure, and through the cooperation of the second limiting structure and the first limiting structure, thereby ensuring the reliability of positioning and limiting of the battery pack 1, and thus ensuring the stability of the installation of the battery pack 1.

[0043] In another embodiment of this application, a first limiting structure is provided at the head of the support guide slide rail 20, and a second limiting structure is provided at the head of the battery pack 1 for cooperating with the first limiting structure. This allows the battery pack 1 to achieve a limiting connection with the support guide slide rail 20 through the cooperation of the second limiting structure and the first limiting structure, thereby ensuring the reliability of the limiting of the battery pack 1 and ensuring the stability of the installation of the battery pack 1.

[0044] It should be noted that in this application, the first positioning structure and the second positioning structure are concave-convex in the direction in which the battery pack 1 slides into the battery compartment 11. Thus, by using this concave-convex fit between the first and second positioning structures in the direction in which the battery pack 1 slides into the battery compartment 11, the concave-convex fit between the first and second positioning structures can be achieved just as the battery pack 1 is about to slide into its final position during the process of sliding into the battery compartment 11 along the extension direction of the support guide rail 20. This makes the operation convenient, quick, and the positioning accurate.

[0045] It should be noted that in this application, the support guide slide rail 20 is installed in the battery compartment 11 through the support frame 40. Of course, it is also possible that the support guide slide rail 20 is connected to the two side walls of the battery compartment 11 that are opposite to each other.

[0046] like Figures 3 to 11 As shown, the first positioning structure is a first positioning post 231 protruding from the tail of the supporting guide slide rail 20, and the second positioning structure is a first positioning hole 101 opened at the tail of the battery pack 1. In this way, the precise positioning of the battery pack 1 is achieved through the cooperation of the first positioning post 231 and the first positioning hole 101.

[0047] like Figures 3 to 11As shown, the first positioning structure is a first positioning post 231 protruding from the tail of the support guide slide rail 20, and the second positioning structure is a first positioning hole 101 opened at the tail of the battery pack 1. The support guide slide rail 20 includes a slide rail body 21, a support block 22, and a positioning structure 23. The slide rail body 21 is located inside the battery compartment 11. The support block 22 is vertically arranged at the tail of the slide rail body 21, and the support block 22 is provided with a clearance through hole 221 for avoiding the first positioning post 231. A third positioning post 222 protrudes from the side surface of the support block 22 away from the battery pack 1. The positioning structure 23 protrudes from the first positioning post 231, and the positioning structure 23 is also provided with a third positioning hole 232 for cooperating with the third positioning post 222. In this way, by setting the support guide slide rail 20 into a structure including slide rail body 21, support block 22 and positioning structure 23, the reliability of the connection between the support guide slide rail 20 and the side wall of the battery compartment 11 through the slide rail body 21 is ensured. The setting of the support block 22 plays a supporting and limiting role for the positioning structure 23. By setting the first positioning post 231 protruding on the positioning structure 23 and opening the first positioning hole 101 on the battery pack 1, the reliability of the cooperation between the first positioning post 231 and the first positioning hole 101 is ensured. In addition, the cooperation between the third positioning post 222 and the third positioning hole 232 ensures the reliability of the connection between the positioning structure 23 and the support block 22.

[0048] It should be noted that in this application, the support frame 40 is fixed inside the battery compartment 11, and the slide rail body 21 is connected to the support frame 40; of course, the slide rail body 21 can also be directly connected to the side wall of the battery compartment 11.

[0049] In one exemplary embodiment, there are multiple third positioning posts 222, with at least two of them located on opposite radial sides of the clearance hole 221; there are multiple third positioning holes 232, each corresponding to one of the multiple third positioning posts 222. This combination of multiple third positioning holes 232 and multiple third positioning posts 222 increases the number of connection points between the positioning structure 23 and the support block 22, thereby ensuring the reliability of the connection between the positioning structure 23 and the support block 22.

[0050] like Figures 3 to 11As shown, there are two third positioning posts 222, which are located on the radial sides of the clearance through hole 221 in the height direction of the energy storage cabinet; there are two third positioning holes 232, which correspond one-to-one with the two third positioning posts 222; one of the third positioning holes 232 has a circular cross-section, and the cross-sectional area of ​​the circular third positioning hole 232 is larger than the cross-sectional area of ​​the third positioning post 222; the other third positioning hole 232 has an oblong cross-section, and the oblong third positioning hole 232 extends along the height direction of the energy storage cabinet. Thus, one of the two third positioning holes 232 has a circular cross-section, and the cross-sectional area of ​​the circular third positioning hole 232 is larger than the cross-sectional area of ​​the third positioning post 222. Meanwhile, the other third positioning hole 232 has an oblong cross-section, and the oblong third positioning hole 232 extends along the height direction of the energy storage cabinet. When the battery pack 1 is slid into the battery compartment 11, due to the error in the connection between the slide rail body 21 and the side wall of the battery compartment 11, in order to ensure that the first positioning post 231 and the first positioning hole 101 can be effectively inserted and engaged, after the battery pack 1 is slid into the battery compartment 11 along the support guide slide rail 20, the positioning structure 23 can be positioned relative to the support block 22 through the circular third positioning hole 232 and the oblong third positioning hole 232 on it, according to the actual sliding position of the battery pack 1, to ensure that the first positioning post 231 and the first positioning hole 101 can be effectively positioned and engaged.

[0051] Of course, in order to ensure the reliability of the movement of the positioning structure 23, the cross-sectional area of ​​the bypass hole 221 is greater than the cross-sectional area of ​​the first positioning post 231 on the positioning structure 23, so as to ensure that the bypass hole 221 will not affect the movement adjustment of the positioning structure 23.

[0052] It should be noted that, in an embodiment of this application (not shown), the cross-sections of both third positioning holes 232 are cross-shaped, and the cross-shaped third positioning holes 232 extend along the height and width directions of the energy storage cabinet, respectively. Thus, by making the cross-sections of both third positioning holes 232 cross-shaped and extending the cross-shaped third positioning holes 232 along the height and width directions of the energy storage cabinet, it is ensured that the positioning structure 23 can be adjusted in either the height or width direction of the energy storage cabinet.

[0053] It should be noted that, in this application, the difference between the diameter d1 of the circular third positioning hole 232 and the diameter of the third positioning post 222 ranges from 4 to 6 mm; or, the center distance d2 of the waist-shaped third positioning hole 232 ranges from 4 to 6 mm. Thus, by reasonably optimizing the range of the difference between the diameter d1 of the circular third positioning hole 232 and the diameter of the third positioning post 222, the ease of position adjustment and the reliability of movement of the positioning structure 23 are ensured; or, by reasonably optimizing the range of the center distance d2 of the waist-shaped third positioning hole 232, the ease of position adjustment and the reliability of movement of the positioning structure 23 are ensured.

[0054] It should be noted that, in this application, the line connecting the geometric centers of the two third positioning holes 232 passes through the same diameter of the first positioning post 231.

[0055] It should be noted that in this application, there are at least two third positioning posts 222, and at least two of the third positioning posts 222 are first studs. The number of third positioning holes 232 is the same as the number of first studs and they correspond one-to-one. The supporting guide slide rail 20 also includes first nuts 24, and the number of first nuts 24 is the same as the number of first studs and they correspond one-to-one. Each first stud passes through its corresponding third positioning hole 232 and is connected to its corresponding first nut 24. In this way, by tightening the corresponding first studs with the first nuts 24, the reliability and convenience of the connection between the positioning structure 23 and the support block 22 are ensured.

[0056] It should be noted that, in this application, if Figure 13 and Figure 14 As shown, the first limiting structure is a first limiting hole opened on the support guide slide rail 20; the head of the battery pack 1 is provided with a lug structure 102, and a second limiting hole is opened on the lug structure 102. The second limiting structure is a second stud 103 that passes through the second limiting hole; the energy storage cabinet also includes a second nut 30, and the second stud 103 passes through the second limiting hole and the first limiting hole in sequence and is connected to the second nut 30. In this way, the head of the battery pack 1 and the head of the support guide slide rail 20 are fastened together by the first and second studs 103 and the second nut 30, ensuring the reliability of the limiting of the battery pack 1.

[0057] It should be noted that, in an embodiment of this application (not shown), the first positioning structure is a second positioning hole formed at the tail of the supporting guide rail 20, and the second positioning structure is a second positioning post protruding from the tail of the battery pack 1. Thus, the precise positioning of the battery pack 1 is achieved through the cooperation of the second positioning hole and the second positioning post.

The cabinet body 10 has a battery compartment 11 for accommodating a battery pack 1.

And / or, the head of the supporting guide rail 20 is provided with a first limiting structure, and the head of the battery pack 1 is provided with a second limiting structure for cooperating with the first limiting structure.

[0059] In one embodiment of this application, a first positioning structure is provided at the tail of the support guide slide rail 20, and a second positioning structure is provided at the tail of the battery pack 1 for positioning and cooperating with the first positioning structure. This allows the battery pack 1 to achieve positioning connection with the support guide slide rail 20 through the cooperation of the second positioning structure and the first positioning structure, ensuring the positioning reliability of the battery pack 1 and thus ensuring the installation stability of the battery pack 1.

[0060] In another embodiment of this application, a first positioning structure is provided at the tail of the supporting guide slide rail 20, and a second positioning structure is provided at the tail of the battery pack 1 for positioning and cooperating with the first positioning structure; and a first limiting structure is provided at the head of the supporting guide slide rail 20, and a second limiting structure is provided at the head of the battery pack 1 for cooperating with the first limiting structure, so that the battery pack 1 achieves positioning and limiting connection with the supporting guide slide rail 20 through the cooperation of the second positioning structure and the first positioning structure, and through the cooperation of the second limiting structure and the first limiting structure, thereby ensuring the reliability of positioning and limiting of the battery pack 1, and thus ensuring the stability of the installation of the battery pack 1.
