The energy storage device includes an energy storage box and a battery pack, and the energy storage box includes a box body and a guide rail structure in the embodiment of the present application. Figure 1 Schematic diagram of the structure of energy storage devices in some embodiments.

[0044] Reference Figure 1In some embodiments, a mounting frame 30 is provided in the energy storage box 100, and multiple layers of guide rail layers are vertically spaced apart in the box body 20, each guide rail layer includes multiple guide rail structures 10, and each guide rail structure 10 is installed on the mounting frame 30. The guide rail structures 10 of each guide rail layer are arranged at intervals on the same horizontal plane. A battery installation space for inserting the battery pack 200 is formed between adjacent guide rail layers. In actual application, the guide rail structures 10 of each guide rail layer jointly guide the battery pack 200 to be inserted into the battery installation space along the longitudinal direction of the guide rail structure 10, and are supported on the guide rail structure 10. Typically, but not limited to, the number of guide rail structures 10 in each guide rail layer is two. The two guide rail structures 10 of each guide rail layer are arranged on both sides of the battery pack 200.

[0045] The battery pack 200 generally includes a housing and a plurality of battery cells arranged in the housing. The plurality of battery cells may be arranged in parallel or in series in the housing. A battery management system for managing the battery cells and a thermal management system for thermal management of the battery cells may also be provided in the battery pack 200. The battery cell is the smallest unit for performing electrochemical reactions in the battery pack 200, and generally includes a housing, an electrode assembly loaded in the housing, an electrolyte, etc. The electrode assembly is generally formed by lamination or winding of a positive electrode sheet, a negative electrode sheet, and a separator. Please refer to the conventional settings for the specific structure of the battery cell.

[0046] Figure 2 is a schematic rear view of a battery pack 200 in some embodiments, Figure 3 200 is a front view of a battery pack 200 of some embodiments. Figure 2 and Figure 3 The box body of the battery pack 200 includes a lower box body 201 and an upper box body 202 . The upper box body 202 is arranged above the lower box body 201 . The upper box body 202 and the lower box body 201 are connected to each other to form an internal space of the battery pack 200 .

[0047] Further, refer to Figure 2 and Figure 3 The lower box 201 includes a protruding edge that is protruding relative to the upper box 202. In actual application, the battery pack 200 can be inserted and supported on the guide rail structure 10 through the protruding edge of the lower box 201. It should be noted that the protruding edge is optional. For a battery pack 200 that does not include the protruding edge, it can also be directly supported on the guide rail structure 10 through the bottom side edge of the lower box 201.

[0048] In some embodiments, reference Figure 2 The rear end of the lower box 201 of the battery pack 200 is provided with a cavity hole g, which can reduce the weight of the battery pack 200 and can be inserted into the limiting member 13 on the guide rail structure 10. In some embodiments, referring to Figure 3A locking hole s is provided at the front end of the lower box body 201 of the battery pack 200 for fixing the battery pack 200 to the locking member 12 of the guide rail structure 10 .

[0049] In some embodiments, the mounting frame 30 includes a plurality of columns, each of which is fixed in the box body 20, and the guide rail structure 10 is installed on the columns. The plurality of columns are arranged at intervals in the lateral direction of the guide rail structure 10, and the two guide rail structures 10 of each guide rail layer are installed on opposite sides of two adjacent columns.

[0050] The guide rail structure 10 in the embodiment of the present application is described in detail below.

[0051] Figure 4 Schematic diagram of the exploded view of the guide rail structure 10 in some embodiments. Figure 5 for Figure 4 A partial structural schematic diagram of the guide rail structure 10 is shown.

[0052] Please refer to Figure 4 and Figure 5 The guide rail structure 10 provided in the embodiment of the present application includes a support rail 11, a locking member 12 and a limiting member 13. The support rail 11 includes a first end D1 and a second end D2 which are arranged opposite to each other in the longitudinal direction. The first end D1 is configured to allow the battery pack 200 to be inserted and supported on the support rail 11 along the longitudinal direction. The locking member 12 has an assembly state and a locking state relative to the first end D1. When the locking member 12 is in the assembly state, the battery pack 200 is allowed to be inserted from the first end D1. When the locking member 12 is in the locking state, it is fixedly connected with the battery pack 200 located on the support rail 11. The limiting member 13 is arranged at the second end D2. The limiting member 13 includes a limiting surface 13f and a plug-in matching structure 13g. The limiting surface 13f is arranged facing the first end D1 and is used to abut against the battery pack 200 located on the support rail 11. The plug-in matching structure 13g is used to plug with the battery pack 200 located on the support rail 11 along the longitudinal direction.

[0053] The longitudinal direction of the support rail 11 is its extension direction, and its transverse direction is perpendicular to its longitudinal direction. The longitudinal dimension of the support rail 11 is greater than its transverse dimension. In practical applications, the longitudinal and transverse directions of the support rail 11 are both horizontal directions. Figure 4 In the structure shown, X represents the longitudinal direction of the support rail 11, Y represents the transverse direction of the support rail 11, and Z represents the vertical direction.

[0054] The first end D1 is the front end of the support rail 11, and the second end D2 is the rear end of the support rail 11. In actual application, the battery pack 200 is inserted into the support rail 11 along the longitudinal direction from the first end D1 of the support rail 11 and supported on the support rail 11 until the battery pack 200 abuts against the limiting surface 13f of the limiting member 13 at the second end D2, and the battery pack 200 is inserted into place.

[0055] The locking member 12 has an assembled state and a locked state relative to the first end D1, and can switch between the two states. Specifically, the locking member 12 can be detachably arranged at the first end D1. Before inserting the battery pack 200, the locking member 12 (such as a locking bolt) is removed from the first end D1 so as not to interfere with the insertion of the battery pack 200. When the battery pack 200 is inserted into place, the locking member 12 is reinstalled on the first end D1, and the locking member 12 can be locked to the front end of the battery pack 200 through the locking hole s on the battery pack 200. Of course, the locking member 12 can also be always arranged at the first end D1, for example, the locking member 12 can be rotatably arranged at the first end D1, and it can switch between the assembled state and the locked state when rotating.

[0056] The limiting member 13 includes a limiting surface 13f and a plug-in matching structure 13g. The plug-in matching structure 13g may be a protruding structure protruding toward the first end D1 relative to the limiting surface 13f, or may be a recessed structure recessed away from the first end D1, as long as it can be plugged into the corresponding plug-in position on the battery pack 200. When the battery pack 200 is plugged into place, the limiting surface 13f limits the battery pack 200 in the longitudinal direction. At the same time, the plug-in matching structure 13g is smoothly plugged into the corresponding plug-in position on the battery pack 200, and the plug-in matching structure 13g cooperates with the corresponding plug-in position to limit the rear end of the battery pack 200 in the vertical and horizontal directions.

[0057] In a specific embodiment, a cavity hole g is provided at a corresponding plug-in position on the battery pack 200, and the plug-in matching structure 13gze may be a protruding structure protruding from the limiting surface 13f.

[0058] When the guide rail structure 10 is applied to the energy storage box 100 of the energy storage device 1000, when the battery pack 200 is inserted into place on the support rail 11, the limiting surface 13f of the limiting member 13 cooperates with the locking member 12 to limit the battery pack 200 in the front-to-back direction, and at the same time, the plug-in matching structure 13g of the limiting member 13 can limit the rear end of the battery pack 200 in the horizontal and vertical directions. Compared with the solution in the related art that only locks the front end of the battery pack 200, the solution of the embodiment of the present application also uses the limiting surface 13f and the plug-in matching structure 13g to limit the rear end of the battery pack 200 in the longitudinal, horizontal and vertical directions, so that the battery pack 200 is installed more reliably, the transportation process of the battery pack 200 is safer, and the safety hazards of the battery pack 200 are reduced.

[0059] Specifically in the embodiment, refer to Figure 1The limiting member 13 includes a first bent piece arranged at an angle with the support rail 11, and the first bent piece includes a surface facing the first end D1, and the surface constitutes a limiting surface 13f. A second bent piece is provided on the first bent piece, which is arranged at an angle with the first bent piece, and the second bent piece extends horizontally toward the first end D1, and the second bent piece constitutes a plug-in matching structure 13g. With such a structure, the limiting member 13 and the support rail 11 can be stamped and formed as an integrated whole, thereby reducing production costs.

[0060] In some embodiments, reference Figure 5 , a buffer layer 13h is provided on the limiting surface 13f. The buffer layer 13h can be a layer structure with buffering and energy absorption effect, such as a rubber layer, a silicone layer, a sponge layer, etc., which can be provided on the limiting surface 13f by bonding, fastening connection, etc. If the plug-in matching structure 13g is provided on the limiting surface 13f, the plug-in matching structure 13g and the buffer layer 13h are staggered to avoid interference between the two.

[0061] During the insertion of the battery pack 200, the buffer layer 13h can make the rear end of the battery pack 200 flexibly contact with the limiter 13, reducing the probability of the battery pack 200 and the limiter 13 being damaged due to rigid contact, and playing a certain protective role for the battery pack 200 and the guide rail structure 10.

[0062] In some embodiments, the support rail 11 includes a support plate 11a and a side plate 11b that are intersectingly arranged, both of which are arranged to extend along the longitudinal direction, and the side plate 11b is erected at one end of the support plate 11a in the transverse direction of the guide rail structure 10. The surface of the support plate 11a adjacent to the side plate 11b is a support surface m for supporting the battery pack 200.

[0063] In actual use, the support plate 11a is arranged roughly horizontally, and the support surface m is the upper surface of the support plate 11a. The side plate 11b is roughly vertically arranged on the support plate 11a, which can limit the battery pack 200 to a certain extent in the horizontal direction, guide the battery pack 200 to move linearly along the support plate 11a, and cause less horizontal position deviation.

[0064] When the guide rail structure 10 is applied to the energy storage box 100, the side plates 11b of the two guide rail structures 10 of each guide rail layer are arranged on different sides of the support plate 11a thereof, and the side plates 11b of the two guide rail structures 10 limit the battery pack 200 in the lateral space between them, so that the battery pack 200 can be inserted and installed without derailment. The side of the support plate 11a away from the side plate 11b is open to avoid the battery pack 200.

[0065] The support plate 11a and the side plate 11b can be obtained by bending the same plate blank.

[0066] In some embodiments, the side plate 11b includes a reinforcing folded edge 11c, which is bent laterally toward the side where the support plate 11a is located, and an insertion space k is formed between the reinforcing folded edge 11c and the support surface m.

[0067] The reinforcing fold 11c is usually obtained by bending a part of the side plate 11b. The setting of the reinforcing fold 11c can enhance the strength of the side plate 11b. The reinforcing fold 11c is vertically spaced from the support surface m to form an insertion space k. In actual application, the protruding peripheral edge 201a of the lower box 201 of the battery pack 200 can be inserted into the insertion space k in the longitudinal direction. The insertion space k can be used to limit the battery pack 200 to a certain extent in the vertical direction.

[0068] Specifically, the number of the reinforcing folded edges 11 c may be multiple, and the multiple reinforcing folded edges 11 c are arranged at intervals in the longitudinal direction.

[0069] In some embodiments, reference Figure 4 and Figure 5 The reinforcing fold 11c includes a guiding bevel c1, which is disposed at an end of the reinforcing fold 11c close to the first end D1. Along the direction toward the first end D1, the distance between the guiding bevel c1 and the supporting surface m increases gradually.

[0070] The guiding bevel c1 can be obtained by bending the end of the reinforcing folded edge 11c upward. The two ends of the reinforcing folded edge 11c in the longitudinal direction are recorded as the first folded edge end and the second folded edge end, and the first folded edge end is arranged close to the first end D1, and the guiding bevel c1 is formed at least on the first folded edge end. Of course, for the sake of aesthetics and structural symmetry, so that the structural strength of the side plate 11b is more uniform, the same structure as the guiding bevel c1 can also be arranged on the second folded edge end.

[0071] "The distance between the guiding bevel c1 and the supporting surface m" refers to the distance in the vertical direction, which increases toward the first end D1, thereby forming a trumpet-shaped guiding space between the guiding bevel c1 and the supporting surface m. The battery pack can be smoothly extended into the insertion space under the guidance of the guiding space, thereby improving the convenience of assembly.

[0072] In some embodiments, the guide rail structure 10 includes a buffer spring buckle 11d, which is protrudingly disposed on a lateral side of the side plate 11b close to the support plate 11a, and the buffer spring buckle 11d can be elastically deformed in the lateral direction.

[0073] For the convenience of explanation, the side of the side plate 11b that is close to the support plate 11a in the horizontal direction is recorded as the inner side, and the other side is recorded as the outer side. One end of the buffer spring buckle 11d is fixed to the side plate 11b, and the other end is suspended and protrudes from the inner side of the side plate 11b. The protruding end of the buffer spring buckle 11d is used to abut against the left / right side of the battery pack 200.

[0074] When the size of the battery pack 200 is deviated, the deformation of the buffer spring buckle 11d compensates for the size error of the battery pack 200, ensuring that the battery pack 200 can be smoothly inserted. At the same time, the elastic force provided by the buffer spring buckle 11d can also clamp the battery pack 200, improving the installation reliability of the battery pack 200.

[0075] Figure 6 Schematic side view of the guide rail structure 10 according to some embodiments.

[0076] In some embodiments, reference Figure 6 The guide rail structure 10 includes an insert spring buckle 11e, which is protruding from the other lateral side of the side plate 11b. The insert spring buckle 11e has a root connected to the side plate 11b and an inserting portion e1 extending downward from the root. The inserting portion e1 is protruding from the side surface of the side plate 11b away from the supporting surface m; and along the direction from top to bottom, the distance between the inserting portion e1 and the side plate 11b increases gradually.

[0077] That is, the plug-in spring buckle 11e is protruding from the outside of the side plate 11b, the root of the plug-in spring buckle 11e is fixed to the side plate 11b, the plug-in portion e1 is suspended and tilted from top to bottom away from the side plate 11b, and the lateral interval with the side plate 11b increases during the tilting process.

[0078] When installing the guide rail structure 10, the plug-in portion e1 of the plug-in spring buckle 11e can be inserted into the corresponding hole of the mounting frame 30 to roughly install the guide rail structure 10. In this way, the provision of the plug-in spring buckle 11e not only improves the mounting capacity of the guide rail structure 10, but also facilitates the installation operation of the guide rail structure 10.

[0079] Among them, openings can be provided on the side plate 11b at positions corresponding to the buffer spring buckle 11d and the plug spring buckle 11e. The provision of the openings can not only reduce the material used for the side plate 11b. Moreover, the buffer spring buckle 11d can be deformed and accommodated in the corresponding opening under the push of the battery pack 200, that is, the space in the opening serves as the deformation space of the buffer spring buckle 11d, which helps to reduce the lateral space occupied by the guide rail structure 10 in the energy storage box 100 and improve the space utilization rate of the energy storage box 100.

[0080] At the same time, during the installation of the guide rail structure 10, when the plug-in portion e1 fails to be successfully inserted into the corresponding hole of the mounting frame 30, the plug-in portion e1 can be deformed and accommodated in the opening, which also helps to reduce the lateral space occupied by the guide rail structure 10 in the energy storage box 100 and improve the space utilization rate of the energy storage box 100.

[0081] In some embodiments, reference Figure 4 and Figure 5 The side plate 11b is provided with a mounting portion b1 for mounting the guide rail structure 10 on an external structure.
