Description

Technical Field

[0001] The utility model relates to the technical field of energy storage fixing structures, in particular to a grouping positioning and installation structure for energy storage modules. Background Art

[0002] Common energy storage devices are composed of several battery modules combined and fixed in various arrangements. Common battery modules are mostly fixed in the box as a whole. Once an individual module fails, it is very easy to endanger all other modules. Repair and replacement also require replacement of the entire module. Because the disassembly and reassembly result in differences in the service life of the modules fixed together, such repairs and replacements need to be repeated in the future. This is not only cumbersome, but also significantly shortens the service life of each module. If the entire module is replaced directly, it will incur higher costs. Improving the fixing method and layout method of the energy storage module will help improve this problem. Summary of the Invention

[0012] Figure 2 This is a structural diagram of an energy storage module according to an embodiment of the present invention. DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1-2The energy storage module grouping positioning and installation structure includes a fastening structure 1, which is used to clamp and fix multiple energy storage modules 2 arranged in combination to form an energy storage module 3, and multiple energy storage modules 3 are arranged in a box body 4; mounting bars 5 are respectively provided on both sides of the box body 4 corresponding to the fastening structure 1, and the fastening structure 1 is provided with positioning ears 6 fixedly connected to the mounting bars 5, and multiple energy storage modules 3 are arranged along the length direction of the mounting bars 5; wiring socket brackets 7 are provided at the interface ends corresponding to each of the energy storage modules 3 in the box body 4, and the wiring socket brackets 7 are installed relative to the inner wall of the box body 4 through positioning bars 8, and the energy storage module 3 and the corresponding wiring socket brackets 7 are relatively bound and fixed by a binding structure 9.

[0015] The energy storage module in this solution can be a battery unit. As needed, multiple battery units are fixed together in a certain arrangement and combination to form a battery module, and then multiple battery modules are placed in the box to form a complete energy storage device. The internal mounting strips are used to limit and fix the layout positions of multiple battery modules in the box, so that adjacent battery modules are arranged in the box with a relatively fixed spacing. The binding structure is used to make the wiring socket bracket and the energy storage module form a relatively fixed whole, and then the positioning strips are used to position and fix the multiple wiring socket brackets, which can completely fix the relative positions of the multiple energy storage modules in the box. The wiring socket bracket is used to merge and connect multiple battery module interfaces of the battery module to one interface, and is connected to the control panel in the box and the external interface of the box through a wiring lead, thereby reducing the number of wiring between the battery modules in the box. Under the premise of the same energy storage capacity, this solution divides the original large-scale battery module into multiple small-scale battery modules, and leaves a certain distance between them, so as to reduce the possibility of local failure endangering all modules. Each small-scale battery module can be replaced individually without affecting the status of other modules, thereby ensuring that each battery module maintains a longer service life as possible. The layout and fixing method of each battery module in the box facilitates the inspection and replacement of the battery modules inside the box.

[0016] The fastening structure 1 is provided with two clamping plate structures 11. The folded ears on both sides of the two clamping plate structures 11 correspond to each other and fit together to form an annular structure that wraps and clamps the multiple energy storage modules 2. The two folded ears that fit together are fixedly connected to form the positioning ears 6. The two clamping plate structures are stamped into a consistent shape. The middle part of the folded ears on both sides is a receiving groove adapted to the battery pack. The two clamping plate structures are symmetrically fitted on both sides of the battery pack so that the folded ears of the two clamping plate structures fit together and are tightened and fixed by a bolt and nut structure. An elastic insulating partition is provided between the clamping plate structure and the battery module to protect the internal battery module.

[0017] The positioning ear 6 is provided with a plurality of limiting columns 61 on the side close to the mounting bar 5, and a limiting slide groove is provided on the mounting bar 5. The limiting columns 61 are inserted into and matched with the limiting slide groove, and the limiting columns 61 slide and match along the groove direction of the limiting slide groove, and the groove direction of the limiting slide groove is set perpendicular to the length direction of the mounting bar 5; the positioning ear 6 is also provided with a mounting notch 62, and the mounting notch 62 corresponds to the mounting hole on the mounting bar 5.

[0018] The limiting posts can be the ends of bolts used to securely connect the folding ears on both sides. Since the limiting slots are fixedly provided on the mounting bar and are arranged at fixed distances along the length of the mounting bar, inserting the limiting posts into the limiting slots can effectively constrain the distance of the energy storage module in the length direction of the mounting bar, while allowing a certain range of movement in the direction perpendicular to the length of the mounting bar. The wiring socket bracket 7 is then positioned and fixed to constrain the movement of the energy storage module in the direction of the limiting slots, thereby achieving complete fixation of the battery module. The mounting notches and mounting holes are used for fastening screws to pass through and tighten with nuts on the back side of the mounting bar to achieve a fixed connection between the positioning ears and the mounting bar.

[0019] The same end of two adjacent wiring socket brackets 7 is fixedly connected to the inner wall of the box body 4 via a positioning bar 8; the other ends are fixedly connected to each other via the same positioning bar 8, which is also fixedly connected to the inner wall of the box body 4. This ensures that the positional relationship of each wiring socket bracket relative to the interior of the box is fixed, and also ensures that the relative positional relationship between adjacent wiring socket brackets is fixed.

[0020] A limiting groove 71 is provided on the side of the wiring socket bracket 7 away from the energy storage module 3. The binding structure 9 is inserted into the limiting groove 71 and is arranged on the outside of the energy storage module 3 and the corresponding wiring socket bracket 7 in a direction perpendicular to the circumferential direction of the fastening structure 1. It can cooperate with the fastening structure and work together to make the battery modules of the arranged and assembled battery modules fit more tightly and not easily loose, thereby ensuring the stability of the overall structure of the energy storage module. The binding structure can be made of metal strips, and the joints are connected by welding. The position of the binding structure can be limited by the limiting groove to prevent it from moving and affecting the stability of the energy storage module.

[0021] The wiring socket bracket 7 is spaced apart from the interface end of the energy storage module 3. The width of the clamping structure 11 matches the size of the energy storage module 2. The clamping structure 11 is provided with ears 12 extending from the clamping structure 11 corresponding to the binding position of the binding structure 9. The ears 12 are aligned with the side faces of the wiring socket bracket 7. Limiting notches are provided at positions corresponding to the limiting grooves 71, and the limiting notches are provided for the binding structure 9 to engage. The ears extending from both sides are symmetrically aligned with the two sides of the wiring socket bracket. Due to the binding and restraining action of the binding structure, the ears clamp the wiring socket bracket, forming a stable wiring space between the wiring socket bracket and the wiring end face of the battery module. The relative forces exerted on the wiring socket bracket by the positioning strips and the binding structure help maintain the stable force applied to the wiring socket bracket, thereby ensuring its secure installation and preventing the gap between the wiring socket bracket and the energy storage module from fluctuating, thereby preventing any impact on the wiring between the two.

[0022] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
