DETAILED DESCRIPTION

[0046] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0047] In response to the technical problems existing in the prior art, the basic technical concept of the utility model is to design the supporting guide rails in the battery cluster frame into a "thickened support in the middle and fixed at both ends" structure. By setting an upper fixing part and a lower fixing part, the position and number of the fixing parts are increased, and the middle supporting part is connected between the upper fixing part and the lower fixing part, which has better fixing and supporting effects and can improve the support stability and safety.

[0048] Embodiment of the battery cluster frame in the utility model:

[0049] like Figure 1 and Figure 2 As shown, the battery cluster rack includes a frame body 1, on which a support rail 2 is installed. Specifically, the frame body 1 includes a column 1-1, and the front and rear ends of the support rail 2 are respectively installed on the front and rear columns 1-1 by bolts 3. A plurality of support rails 2 are installed along the up and down directions. The frame body 1 includes a plurality of left and right arranged columns 1-1, and two left and right oppositely arranged support rails 2 are used to support a battery box.

[0050] like Figure 3 As shown, the support rail 2 is formed by bending a plate with uniform thickness in one piece, and the support rail 2 includes an upper fixing portion 2-1, a lower fixing portion 2-2, and an intermediate supporting portion located between the upper fixing portion 2-1 and the lower fixing portion 2-2. The thickness directions of the upper fixing portion 2-1 and the lower fixing portion 2-2 are both in the left-right direction, and the upper fixing portion 2-1 and the lower fixing portion 2-2 are respectively provided with mounting structures for fixing and mounting on the frame body 1. Since the support rail 2 is fixed to the front and rear columns 1-1 of the frame body 1 by bolts 3, the mounting structure on the upper fixing portion 2-1 is an upper bolt mounting hole 2-8 for mounting the bolt 3, and the mounting structure on the lower fixing portion 2-2 is a lower bolt mounting hole 2-9 for mounting the bolt 3. Furthermore, the upper bolt mounting holes 2-8 and the lower bolt mounting holes 2-9 are arranged in pairs, and a pair of upper bolt mounting holes 2-8 are respectively provided at the front and rear ends of the upper fixing portion 2-1, and a pair of lower bolt mounting holes 2-9 are respectively provided at the front and rear ends of the lower fixing portion 2-2, so as to ensure the fixed connection strength.

[0051] The thickness direction of the middle support portion is perpendicular to the thickness direction of the upper fixing portion 2-1 and the lower fixing portion 2-2. Figure 3 As shown, since the support rail 2 is formed by integrally bending the plate, the middle support portion includes a double-layer stacked plate 2-3. In addition, the middle support portion also includes a fixed plate 2-4 separately fixed on the upper surface of the double-layer stacked plate 2-3. The top surface of the fixed plate 2-4 constitutes a support surface for supporting the battery box. The thickness of the entire middle support portion is greater than the thickness of the upper fixed portion 2-1 and the lower fixed portion 2-2, respectively, thereby ensuring the structural strength of the middle support portion itself and the support stability for the battery box.

[0052] In this embodiment, the fixing plate 2-4 is fixed to the double-layer stacking plate 2-3 by screws 2-5, so screw holes are provided on the fixing plate 2-4, and corresponding threaded holes are provided on the double-layer stacking plate 2-3, so that the fixing plate 2-4 can be easily installed and fixed, and in order to ensure the fixing effect, multiple screws 2-5 are used for fixing, and the multiple screws 2-5 are arranged at intervals along the length direction of the fixing plate 2-4. According to the specific length of the fixing plate 2-4, a suitable number of screw holes are provided, and three are provided in this embodiment.

[0053] In this embodiment, the upper fixing portion 2-1 and the double-layer stacking plate 2-3 are integrally connected through a bending limit portion, and the bending limit portion includes a horizontal section 2-6 and a vertical section 2-7 that are vertically connected. The horizontal section 2-6 is connected to the upper fixing portion 2-1, and the vertical section 2-7 is connected to the double-layer stacking plate 2-3, wherein the side of the vertical section 2-7 constitutes a limiting plane for limiting the battery box. When installing the battery box, first place the battery box on two support rails 2 arranged opposite to each other on the left and right, and push the battery box backward along the upper surface of the fixing plate 2-4. During the pushing process, the side of the vertical section 2-7 guides and laterally limits the battery box. An accommodating space for accommodating the head of the above-mentioned bolt 3 is enclosed between the upper fixing portion 2-1 and the horizontal section 2-6 to prevent the head of the bolt 3 from protruding from the side of the vertical section 2-7 and interfering with the installation of the battery box.

[0054] The support guide rail 2 of the utility model is formed by bending a plate in one piece, and when bent, a double-layer stacked plate 2-3 is formed in the middle, and an upper fixed part 2-1 and a lower fixed part 2-2 are formed on the upper and lower sides respectively, and a fixed plate 2-4 is fixed on the double-layer stacked plate 2-3, together forming an intermediate support part that is thicker than the upper fixed part 2-1 and the lower fixed part 2-2, forming a "middle thickened support, two end fixed" structural form, increasing the position and number of the fixing part, changing the setting position of the supporting part, having better fixing and supporting effects, being able to improve the support stability and safety, and meeting the support requirements of battery boxes with heavier weight.

[0055] In other embodiments of the battery cluster rack: the mounting structure on the lower fixing portion may not be a bolt mounting hole, but a welded stud fixed to the lower fixing portion by welding. During installation, the welded stud passes through the column of the battery cluster rack, and then cooperates with the nut to connect, so that the lower fixing portion is fixed to the column. Similarly, the mounting structure on the upper fixing portion may not be a bolt mounting hole, but a welded stud fixed to the upper fixing portion by welding. During installation, the welded stud passes through the column of the battery cluster rack, and then cooperates with the nut to connect, so that the upper fixing portion is fixed to the column. Of course, in other embodiments, the support rails may also be welded and fixed to the column. In this case, the mounting structures on the upper fixing portion and the lower fixing portion are both welding grooves reserved on the edges.

[0056] In other embodiments of the battery cluster rack: the fixing plate can also be fixed to the upper surface of the double-layer stacked plate by gluing, and in this case, no screw holes and threaded holes are required. In other embodiments, the fixing plate can also be fixed to the double-layer stacked plate by welding.

[0057] In other embodiments of the battery cluster rack: when the support rail is formed by integrally bending a plate, the middle support portion can be directly formed by a double-layer stacked plate, that is, no fixed plate is provided. At this time, the upper surface of the double-layer stacked plate constitutes a support surface for supporting the battery box.

[0058] In other embodiments of the battery cluster rack: the support rails can also be integrally formed by injection molding, in which case the middle support portion is an integral structure, and the thickness of the middle support portion can be made greater than the thickness of the upper fixing portion and the lower fixing portion.

[0059] In other embodiments of the battery cluster rack: when the support guide rail is integrally formed by injection molding, the thickness of the middle support portion can also be equal to the thickness of the upper fixed portion and the lower fixed portion, respectively. Of course, if the support guide rail is integrally bent from a plate, by using plates with unequal thicknesses, such as bending a plate that is thin in the middle and thick at both ends, the thickness of the middle support portion can also be equal to the thickness of the upper fixed portion and the lower fixed portion.

[0060] In other embodiments of the battery cluster rack: when the mounting structures on the upper fixing part and the lower fixing part are welded studs or the support rails are directly welded and fixed on the columns, since there is no need to avoid the bolt heads, the bending limiter can be omitted on the support rails. At this time, the upper fixing part is directly connected to the middle support part, and the upper fixing part, the lower fixing part and the middle support part are in a "T" shape as a whole. Of course, in other embodiments, even if bolts are used to fix the support rails, the bending limiter can also be omitted on the support rails. It is only necessary to pay more attention when installing the battery box to prevent the battery box from directly hitting the bolt head and being unable to be pushed in.

[0061] In other embodiments of the battery cluster rack, the support rails may not be formed by injection molding or integral bending of a plate, but may be welded parts fixed together.

[0062] The embodiment of the support rail for the battery cluster rack in the utility model is as follows: the specific structure of the support rail for the battery cluster rack is the same as the support rail in the above-mentioned battery cluster rack embodiment, which will not be repeated here.

[0063] The embodiment of the battery cluster in the present invention is as follows: the battery cluster comprises a battery cluster frame and a battery box mounted on the battery cluster frame, wherein the specific structure of the battery cluster frame is the same as the battery cluster frame in the above embodiment and will not be repeated here.

[0064] An embodiment of the energy storage container in the utility model is as follows: the energy storage container includes a box body and a battery cluster arranged in the box body, the battery cluster includes a battery cluster frame and a battery box installed on the battery cluster frame, wherein the specific structure of the battery cluster frame is the same as the battery cluster frame in the above embodiment, and will not be repeated here.
