Description

Technical Field

[0001] This utility model relates to the field of batteries, and in particular to an energy storage battery box. Background Technology

[0002] With the rapid development of renewable energy and the increasing demand for flexible energy storage in power systems, energy storage boxes, due to their modularity and rapid deployment capabilities, are gradually becoming an important solution for grid peak shaving, emergency power supply, and off-grid scenarios. In energy storage boxes, the battery pack, as the core energy storage unit, is the central component. The way the battery pack is secured within the storage box directly affects the safety, shock resistance, maintenance efficiency, and space utilization of the battery system.

[0003] However, in existing energy storage battery boxes, the battery pack is generally only limited and fixed in the front-to-back direction to facilitate its movement and disassembly in case of malfunction. The battery pack is generally not restricted in the vertical direction because battery boxes are typically located in a fixed location and do not move or vibrate vertically. However, for mobile energy storage battery boxes, the battery box needs to move with the vehicle and may experience complex environments during movement, thus placing more stringent requirements on the battery pack's fixation. For example, when the battery pack is in a high-intensity vibration environment, it is prone to movement relative to the battery box, affecting the overall operational stability and safety of the battery box. Utility Model Content

[0004] To address the technical problem in the prior art where the battery pack is unstable in its positioning within the energy storage battery box and is prone to movement relative to the cluster frame, this utility model provides an energy storage battery box, comprising: a battery pack, the battery pack including a supported portion extending in the left-right direction; a cluster frame, the cluster frame being provided with a support plate, the support plate including a longitudinal support portion and a lateral limiting portion, and a limiting block being provided on the support plate;

[0005] Furthermore, it also includes a pressure rod that extends in the front-rear direction. The pressure rod includes a fixed mounting part and a pressing part. The fixed mounting part is connected to the support plate, and the pressing part presses the supported part of the battery pack.

[0006] Furthermore, the pressure bar is L-shaped.

[0007] Furthermore, the fixed mounting part is constructed as a hollow rectangle.

[0008] Furthermore, the pressure bar is made of aluminum.

[0009] Furthermore, the fixed mounting part is provided with screw holes, and the pressure rod is fixed to the support plate by inserting screws into the screw holes.

[0010] Furthermore, a buffer member is provided between the pressure rod and the supported part of the battery pack.

[0011] Furthermore, the pressure rod is provided with a limiting hole, and the support plate is provided with a limiting protrusion, which is inserted into the limiting hole.

[0012] Furthermore, multiple limiting holes are provided.

[0013] The energy storage battery box of this utility model improves the stability of the battery pack within the box by setting a pressure bar to press the supported part of the battery pack, thereby restricting the movement of the battery pack in the vertical direction. This reduces the risk of the battery pack moving due to unstable positioning and improves the safety performance of the battery box. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] The energy storage battery box of this utility model includes a cluster frame 10 and a battery pack 20 mounted on the cluster frame 10. The cluster frame 10 can be installed in the battery box by welding. The cluster frame 10 includes vertical support rods 101 extending in the vertical direction and multiple support plates 102 extending in the front-back direction. In the front-back direction, the multiple vertical support rods 101 are spaced apart, and the support plates 102 are spaced apart in the left-right direction. The support plates 102 and the vertical support rods 101 are connected as a whole by welding. The left and right ends of the battery pack 20 are provided with supported parts (not shown), which can be supported by the support plates 102 and can move relative to the support plates 102 in the front-back direction and be fixed on the cluster frame 10 when pushed by an external force.

[0021] like Figure 1-3 As shown, the support plate 102 extends in the front-to-back direction and is generally L-shaped. The support plate 102 includes a longitudinal support portion 1022 and a transverse limiting portion 1021. The longitudinal support portion 1022 is constructed as a generally rectangular flat plate extending in the front-to-back direction; the transverse limiting portion 1021 is constructed as a generally rectangular plate-like member extending in the vertical direction; the longitudinal support portion 1022 and the transverse limiting portion 1021 are integrally formed and are typically high-strength components stamped from metal materials such as aluminum or steel. A limiting block 40 is also provided on the support plate 102. In the front-to-back direction, the limiting block 40 is located at the middle position of the longitudinal support portion 1022, and the limiting block 40 is connected to the longitudinal support portion 1022 by welding. Figure 1 As shown, the limiting block 40 is Z-shaped. When the battery pack moves in the front-to-back direction, the end of the battery pack abuts against the limiting block 40, preventing the battery pack from moving further in the front-to-back direction, thereby restricting the rearward movement of the battery pack. At the same time, since the limiting block 40 is located in the middle of the longitudinal support 1022, it can simultaneously restrict the movement of two battery packs in the front-to-back direction within the battery box.

[0022] The energy storage battery box of this utility model also includes a pressure rod 30. The pressure rod 30 is a long, L-shaped profile extending in the front-to-back direction. Made of aluminum, the pressure rod 30 includes a fixing mounting part 301 and a pressing part 302. The fixing mounting part 301 is a hollow cuboid extending in the front-to-back direction and has multiple screw holes 303 and limiting holes 304. The pressing part 302 extends from the fixing mounting part 301 in the left-to-right direction, thus making the pressure rod 30 L-shaped, with the pressing part 302 perpendicular to the fixing mounting part 301. In this embodiment, both the fixing mounting part 301 and the pressing part 302 of the pressure rod 30 are designed to be hollow. This hollow profile reduces the overall weight of the pressure rod 30, thereby reducing its manufacturing cost. In this embodiment, a limiting hole 304 is also provided on the fixed mounting part 301. After the battery pack 20 is installed in place, the pressure rod 30 is installed into the battery box. During the installation process, the limiting hole 304 is inserted into the limiting protrusion on the support plate, so that the pressure rod is installed in the corresponding position on the support plate. After the pressure rod is positioned, the pressing part 302 on the pressure rod contacts the supported part on the battery pack and covers the supported part of the battery pack from the top, so that the supported part on the battery pack is clamped between the pressing part 302 on the pressure rod and the longitudinal limiting part 1022 on the support plate, thereby restricting the movement of the battery pack in the vertical direction. Then, the screw 50 is inserted into the screw hole 303 of the pressing rod 30, and the pressure rod is fixed on the support plate 102 by the screw 50. In this embodiment, to reduce the risk of loose fixation between the battery pack and the pressure rod due to friction caused by vibration, a buffer member 60 is provided on the pressing part of the pressure rod and the supported part of the battery pack. The buffer member can be a flexible member such as a sponge, so that there is a buffer between the pressing part 302 and the supported part. When the battery box is vibrated, the buffer member can buffer the friction that may exist between the two, enhance the connection stability between the pressing part 302 and the supported part of the battery pack, reduce the wear of the pressing part 302 caused by the vibration of the battery box, and improve the fixation effect between the pressure rod and the battery pack. In this embodiment, the pressure rod 30 has multiple screw holes. The number of screws can be set according to the size of the battery pack and the length of the pressure rod in the front-to-back direction. When the length of the pressure rod in the front-to-back direction is relatively short, the number of screw holes can be set to be relatively small, such as four or six. When the length of the pressure rod in the front-to-back direction is relatively long, the number of screw holes can be set to be more, such as ten or fourteen. The number of screw holes is not specifically required and can be adjusted according to the length of the pressure rod.In this embodiment, a limiting hole is provided on the pressure rod, and a limiting protrusion is provided on the support plate. However, the assembly method of the limiting hole and the limiting protrusion can be changed according to the specific situation. For example, the limiting protrusion can be provided on the pressure rod, and the limiting hole can be provided on the support plate. This can also play the role of limiting the pressure rod, thereby improving the assembly efficiency and positioning effect of the pressure rod.

[0023] In this embodiment, a front limiting member 80 is also provided at the front end of the battery box. The front limiting member 80 and the battery pack can be fixed by screws 50, thereby limiting the movement of the battery pack towards the front end of the battery box. The movement of the battery pack at the rear end is limited by the limiting block 40, and the movement of the battery pack in the front-to-back direction is limited by the combined action of the limiting block and the front limiting member. The movement of the battery pack in the left-to-right direction is limited by the lateral limiting members 1021 at both ends. Therefore, the battery is stably fixed in the front-to-back, left-to-right, and up-down directions, and thus stably fixed on the battery cluster frame. Even if the battery box is subjected to great vibration during movement, because the battery pack is stably fixed in all directions, it will not move relative to the battery box and can be stably located in the box, which can improve the safety of the battery pack in the box.

[0024] The energy storage battery box of this utility model improves the stability of the battery pack within the box by setting a pressure bar to press the supported part of the battery pack, thereby restricting the movement of the battery pack in the vertical direction. This reduces the risk of the battery pack moving due to unstable positioning and improves the safety performance of the battery box.
