[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least the known structures and technologies of the region are not shown in order to avoid unnecessary ambiguity to the present application; and, for clarity, the size of the regional structure may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0030] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the battery pack bracket 10, battery pack bracket assembly 100 and energy storage system of the present application. In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0031] In order to better understand this application, Figures 1 to 6 The battery pack bracket 10, the battery pack bracket assembly 100 and the energy storage system of the embodiment of the present application are described in detail.

[0032] See also Figure 1 , an embodiment of the present application provides a battery pack bracket 10, including a bracket body 1 and a limiting member 2.

[0033] The bracket body 1 includes a first support plate 11, a second support plate 12 and a connecting plate 13. The first support plate 11 and the second support plate 12 extend along the first direction X and are spaced apart along the second direction Z. The connecting plate 13 connects the first support plate 11 and the second support plate 12 along the second direction Z and encloses a mounting groove. The mounting groove has a mounting channel S extending along the first direction X and an opening connected to the mounting channel S along the third direction Y.

[0034] That is, the first support plate 11, the second support plate 12 and the connecting plate 13 enclose a U-shaped structure having an installation channel S extending along the first direction X. The battery pack 200 can enter through the entrance K1 of the installation channel S and can be moved relative to the installation channel S along the first direction X.

[0035] The limit member 2 is connected to the bracket body 1 and is arranged in the installation groove. The limit member 2 includes a first limit plate 21 and a second limit plate 22 that are arranged to intersect each other. The limit member 2 is blocked at the opening by the first limit plate 21, and is blocked on the extension path of the installation channel S by the second limit plate 22. The third direction Y, the first direction X and the second direction Z intersect each other.

[0036] In the battery pack bracket 10 in the embodiment of the present application, the limiting member 2 is integrally arranged in the installation channel S and includes a first limiting plate 21 and a second limiting plate 22 that are arranged to intersect each other. The first limiting plate 21 and the second limiting plate 22 are respectively blocked at the opening and the extension path of the installation channel S. Therefore, when the battery pack 200 moves to the limiting member 2 relative to the installation channel S, the first limiting plate 21 and the second limiting plate 22 can cooperate with the bracket body to limit the battery pack 200 at a specified position. The overall structure is simple and the cost is low.

[0037] Specifically, when the battery pack 200 moves relative to the installation channel S to the limit member 2, the installation channel S can be used to limit the movement freedom of the battery pack 200 along the second direction Z, and the first limit plate 21 and the second limit plate 22 can be used to limit the movement freedom of the battery pack 200 along the third direction Y and the first direction X, respectively. In this way, the battery pack 200 can be effectively limited in three directions to limit the battery pack 200 at a specified position with higher stability.

[0038] It should be noted that, during actual installation, the first direction X of the bracket body can be set to a vertical direction, the battery pack 200 can fall by gravity, and the second limit plate 22 can be used as a storage plate to support the battery pack 200. Alternatively, the second direction Z of the bracket body can be set to a vertical direction, and the first support plate 11 is located below the second support plate 12 along the vertical direction, so that when the battery pack 200 moves relative to the installation channel S, the first support plate 11 is used as a storage plate to support the battery pack 200. Alternatively, the third direction Y of the bracket body can be set to a vertical direction, so that when the battery pack 200 moves relative to the installation channel S, the connecting plate 13 is used as a storage plate to support the battery pack 200. That is, the setting direction of the bracket body can be adjusted according to the installation direction of the battery pack 200, and it is sufficient to meet the requirements of stable support and fixation of the battery pack 200.

[0039] For the convenience of description, the following description will be made by taking the second direction Z as the vertical direction and the first supporting plate 11 as the storage plate as an example.

[0040] It is understandable that the freedom of movement of the battery pack 200 along the second direction Z is limited by installing the channel S. In some embodiments, the freedom of movement of the battery pack 200 along the second direction Z can be limited directly by using the first support plate 11 and the second support plate 12.

[0041] See also Figure 1 In other embodiments, the limiting member 2 further includes a third limiting plate 23, which is arranged to intersect the first limiting plate 21 and the second limiting plate 22. The third limiting plate 23 is arranged opposite to the first support plate 11 along the second direction Z, and in the second direction Z, the distance between the third limiting plate 23 and the first support plate 11 is smaller than the distance between the second support plate 12 and the first support plate 11.

[0042] That is, only one of the first support plate 11 and the second support, for example, the first support plate 11, can be used. By making the limiting member 2 further include the third limiting plate 23, the third limiting plate 23 and the first support plate 11 can be used to limit the freedom of movement of the battery pack 200 along the second direction Z. Compared with the method of directly using the first support plate 11 and the second support plate 12 for limiting, the above-mentioned setting method can reduce the limitation on the distance between the first support plate 11 and the second support plate 12 along the second direction Z. Therefore, the distance between the first support plate 11 and the second support plate 12 can be appropriately increased to increase the size of the entrance K1 of the installation channel S, so that the battery pack 200 can be more easily entered into the entrance K1 of the installation channel S while achieving reliable limiting of the battery pack 200, thereby reducing the difficulty of installation.

[0043] Among them, when the limiting member 2 includes the first limiting plate 21, the second limiting plate 22 and the third limiting plate 23, any one of the first limiting plate 21, the second limiting plate 22 and the third limiting plate 23 may be connected to the other one, or any one of the first limiting plate 21, the second limiting plate 22 and the third limiting plate 23 may be connected to the other two. Moreover, at least one of the first limiting plate 21, the second limiting plate 22 and the third limiting plate 23 may be connected to the bracket body 1, or the first limiting plate 21, the second limiting plate 22 and the third limiting plate 23 may be connected to the bracket body 1, that is, they can be connected to the support plate body and realize effective limiting and fixing of the battery pack 200.

[0044] The specific structure of the limiting member 2 is described below by taking a specific implementation as an example.

[0045] See also Figure 1 and Figure 2 In some optional embodiments, the third limiting plate 23 is connected to the bracket body 1, the first limiting plate 21 is arranged on the side of the third limiting plate 23 facing the first supporting plate 11 and extends a preset distance along the first direction X. In the first direction X, the first limiting plate 21 is arranged on the side of the second limiting plate 22 away from the entrance K1 of the installation channel S, and is connected to the second limiting plate 22 and the third limiting plate 23, so that the first limiting plate 21, the second limiting plate 22 and the third limiting plate 23 are connected to each other, and the overall stability is better and the reliability is higher.

[0046] Optionally, in the first direction X, the distance between one end of the third limiting plate 23 close to the entrance K1 of the installation channel S and the second limiting plate 22 is greater than the distance between one end of the first limiting plate 21 close to the entrance K1 of the installation channel S and the second limiting plate 22 .

[0047] Based on the above structure, when the battery pack 200 is installed, when the battery pack 200 is moved relative to the installation channel S along the first direction X, the freedom of movement of the battery pack 200 along the second direction Z can be limited by the third limiting plate 23 and the first support plate 11, and then the freedom of movement of the battery pack 200 along the third direction Y can be limited by the first limiting plate 21 arranged on the third limiting plate 23, and then the second limiting plate 22 arranged on the side of the first limiting plate 21 away from the entrance K1 of the installation channel S is pressed against the battery pack 200 to limit the freedom of movement of the battery pack 200 along the first direction X.

[0048] Therefore, during the installation process of the battery pack 200 , only the freedom of movement of the battery pack 200 along a certain direction is gradually restricted, so as to reduce the difficulty of installing the battery pack 200 .

[0049] In order to further reduce the difficulty of installing the battery pack 200, in some optional embodiments, a second guide portion 231 is provided on the side of the third limiting plate 23 facing the entrance K1 of the installation channel S, and along the direction away from the entrance K1 of the installation channel S, the distance between the second guide portion 231 and the first support plate 11 along the second direction Z gradually decreases.

[0050] By providing a second guide portion 231 on the side of the third limiting plate 23 facing the entrance K1 of the installation channel S, after the battery pack 200 enters from the entrance K1 of the installation channel S, the second guide portion 231 can be used to adjust the position of the battery pack 200 along the second direction Z, so as to guide the battery pack 200 between the third limiting plate 23 and the first support plate 11.

[0051] Similarly, a first guide portion 211 is provided on one side of the first limiting plate 21 facing the entrance K1 of the installation channel S. As the distance away from the entrance K1 of the installation channel S, the distance between the first guide portion 211 and the connecting plate 13 along the third direction Y gradually decreases.

[0052] By providing a first guide portion 211 on the side of the first limiting plate 21 facing the entrance K1 of the installation channel S, after the battery pack 200 is introduced between the third limiting plate 23 and the first support plate 11, the first guide portion 211 can be used to adjust the position of the battery pack 200 along the third direction Y, so that the battery pack 200 is introduced between the connecting plate 13 and the first limiting plate 21, thereby achieving installation limitation of the battery pack 200.

[0053] Optionally, the first guide portion 211 and the second guide portion 231 can be configured as inclined plates, the first guide portion 211 is formed by bending the first limit plate 21 and is inclined relative to the first limit plate 21, the second guide portion 231 is formed by bending the third limit plate 23 and is inclined relative to the third limit plate 23, the inclination angle of the first guide portion 211 relative to the first limit plate 21 and the inclination angle of the second guide portion 231 relative to the third limit plate 23 can be adjusted according to the specific structure of the battery pack bracket 10, that is, they can meet the guiding requirements for the installation of the battery pack 200.

[0054] See also Figure 1 and Figure 2 In some optional embodiments, in the first direction X, the stopper 2 is disposed in the central area of ​​the bracket body 1, and the stopper 2 divides the mounting slot into symmetrical sub-mounting slots. The stopper 2 is provided with a first stopper plate 21 and a second stopper plate 22 corresponding to each sub-mounting slot, and the sub-mounting slots arranged in pairs share the same stopper 2.

[0055] By setting the limiting member 2 in the central area of ​​the bracket body, the battery pack bracket 10 can be separated by the limiting member 2 to form symmetrical sub-mounting grooves. The two battery packs 200 can be respectively inserted from the entrances K1 of the symmetrical sub-mounting grooves, and the limiting member 2 set in the central area can be used to limit the two battery packs 200, so that the two battery packs 200 can be installed through the same battery pack bracket 10, thereby increasing space utilization.

[0056] Optionally, the limit member 2 is symmetrically structured relative to the central area of ​​the bracket body 1, that is, the battery pack bracket 10 can be set to a symmetrical structure, and two battery packs 200 can be symmetrically placed to balance the force and simplify the structure of the battery pack bracket 10.

[0057] Please also read Figures 1 to 4 The embodiment of the present application further provides a battery pack bracket assembly 100, including a battery rack group 20 and a battery pack bracket 10, the battery pack bracket 10 is the battery pack bracket 10 in any of the above embodiments, and the battery pack bracket 10 is arranged on the battery rack group 20 at intervals along the second direction Z, so that multiple battery packs 200 can be installed on the battery pack bracket assembly 100 along the first direction X, thereby realizing the integration of multiple battery packs 200.

[0058] For each battery rack group 20, it may include more than two battery racks 210, and the more than two battery racks 210 are arranged at intervals along the first direction X. Each battery rack 210 is provided with a first connection hole, and the battery pack bracket 10 is provided with a plurality of second connection holes 131 at intervals along the first direction X. The battery pack bracket assembly 100 also includes bolts, which pass through the second connection holes 131 and the first connection holes in sequence, and fix the battery pack bracket 10 to the battery rack 210 to form a multi-point connection of the battery pack bracket 10, increase the stability of the battery pack bracket 10, and achieve reliable installation of the battery pack 200.

[0059] In addition, one of the battery rack 210 and the battery pack holder 10 may be provided with a recessed portion, and the other may be provided with a protruding portion 14. When the battery pack holder 10 is fixed to the battery rack 210, the battery pack holder 10 may be positioned by the recessed portion and the protruding portion 14, so as to facilitate the positioning and installation of the battery pack holder 10 on multiple battery racks 210.

[0060] To further achieve reliable installation of the battery pack 200, in some optional embodiments, the battery pack bracket assembly 100 includes N battery rack groups 20 arranged at intervals along a third direction Y, N ≥ 2, and battery pack brackets 10 are arranged on the surfaces of two adjacent battery rack groups 20 facing each other.

[0061] By arranging battery pack brackets 10 on the surfaces facing each other of two adjacent battery rack groups 20, when installing the battery pack 200, the battery pack 200 can be arranged between the two adjacent battery rack groups 20 along the third direction Y, and the battery pack brackets 10 on both sides can be used to limit and support the battery pack 200, thereby improving the reliability of the installation of the battery pack 200.

[0062] Specifically, in the first direction X, the battery pack holders 10 arranged opposite to each other form an entrance K1 of the installation channel S on the same side, so when installing the battery pack 200, the two ends of the battery pack 200 along the third direction Y can be synchronously installed at the entrance K1 of the installation channel S, and the battery pack 200 can be moved relative to the installation channel S along the first direction X. When the battery pack 200 moves to a specified position, the installation limit of the battery pack 200 can be synchronously achieved through the limit members 2 on the battery pack holders 10 on both sides, and the entire installation structure is simpler and more reliable.

[0063] See also Figures 3 to 6Since the battery pack 200 has only the freedom of movement to exit from the entrance K1 of the installation channel S in the first direction X after the battery pack support 10 is installed and limited, in some optional embodiments, the battery pack support assembly 100 further includes an end plate 30, which is connected to at least one of the battery rack assembly 20 and the battery pack support 10, and is disposed at the entrance K1 of the installation channel S on the battery pack support 10 in the first direction X. By arranging the end plate 30 at the entrance K1 of the installation channel S on the battery pack support 10, the battery pack 200 can be fixed in the installation channel S, thereby achieving the position fixation of the battery pack 200 and making the battery pack 200 more stable.

[0064] Among them, the bracket body 1 may be provided with a third connecting hole 15 near the entrance K1 of the installation channel S, and the end plate 30 may be provided with a fourth connecting hole 310. The battery pack bracket assembly 100 also includes bolts, which are sequentially passed through the fourth connecting hole 310 and connected to the third connecting hole 15, thereby connecting the end plate 30 to one end of the battery pack bracket 10.

[0065] Optionally, in addition to the fourth connection hole 310, the end plate 30 may also be provided with a fifth connection hole 320, which is used to cooperate with the battery pack 200, so that after the battery pack 200 is installed on the battery pack bracket 10, the end plate 30 is simultaneously connected to the battery pack 200 and the battery pack bracket 10, further improving the position fixing of the battery pack 200. In addition, the end plate 30 may also be provided with a first threading hole 330 and a second threading hole 340, which are respectively used to fix the wiring harness and pipeline of the battery pack 200 to ensure the function of the battery pack 200.

[0066] It can be understood that when N≥3, the multiple battery rack groups 20 include battery rack groups 20 located at both ends and battery rack groups 20 located in the middle. In the third direction Y, the battery rack groups 20 located at both ends are only provided with battery pack brackets 10 on one side, and the battery rack group 20 located in the middle is provided with battery pack brackets 10 on both side surfaces along the third direction Y.

[0067] Therefore, in this case, in some optional embodiments, the paired battery pack brackets 10 on the Mth battery rack group 20 share the same end plate 30, 1<M<N, N≥3.

[0068] That is, the end plates 30 of the battery rack group 20 can be set to different structures. For the convenience of description, the end plates 30 on the battery rack groups 20 located at both ends are defined as first end plates 30a, and the end plates 30 on the battery rack group 20 located in the middle are defined as second end plates 30b. Since the battery pack holders 10 are provided on the two side surfaces of the battery rack group 20 located in the middle along the third direction Y, the length of the second end plate 30b along the third direction Y can be extended so that the projection of the second end plate 30b along the first direction X can cover the battery pack holders 10 on both sides of the battery rack group 20. Then, the battery pack holders 10 on both sides can share the same second end plate 30b to simplify the structure of the battery pack holder assembly 100.

[0069] The embodiment of the present application also discloses an energy storage system, including a battery pack 200 and the battery pack bracket assembly 100 in the above embodiment, and the battery pack 200 is installed on the battery pack bracket assembly 100. Since the energy storage system includes the battery pack bracket assembly 100 in the above embodiment, it also has the characteristics of easy installation, reliable limiting, and low cost, and is more convenient for promotion and application.

[0070] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
