Description

Technical Field

[0001] This utility model relates to the field of battery stacking bracket technology, and in particular to a self-locking stacking bracket for energy storage batteries. Background Technology

[0002] Against the backdrop of the rapid development of the energy storage industry, energy storage batteries, as the core component for energy storage and release, have placed higher demands on the installation, stacking, and operation and maintenance efficiency of batteries due to their large-scale application. Self-locking stacking brackets for energy storage batteries are a modular support device designed specifically for energy storage batteries. Their core feature is that they achieve the "self-locking" function through mechanical structure, while also supporting the multi-layer stacking installation of battery cells.

[0003] Traditional support brackets are inefficient to assemble and disassemble, and usually use rigid connections such as bolts. Disassembly requires tools to operate one by one, which is time-consuming and laborious. In addition, the self-locking stability is insufficient, and they are easily loosened due to natural vibration and environmental bumps, making it difficult to meet the requirements of long-term stable operation. Furthermore, the batteries are not firmly fixed and are prone to shaking and displacement. Based on this, a self-locking stacking bracket for energy storage batteries is proposed for improvement. Utility Model Content

[0004] In view of the aforementioned problems of low disassembly and assembly efficiency and insufficient self-locking stability, this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a self-locking stacking bracket for energy storage batteries, including a battery body, a plurality of C-shaped frames are rectangularly distributed on the outer side of the battery body, the C-shaped frames include a self-locking mechanism, and a fixing seat is fixedly connected to the upper outer side of the C-shaped frame by bolts; The upper parts of both sides of the fixed base are rotatably connected to a rotating shaft. The same movable shell is movably connected to the opposite side of the rotating shaft. A limit frame is movably connected inside the movable shell. A spring is movably connected to the bottom wall of the inner side of the limit frame. The top of the spring is fixedly connected to the inner wall of the movable shell.

[0006] As a preferred embodiment, the lower outer part of the C-shaped frame is fixedly connected to a hook by bolts, and the top crossbar of the limiting frame is fitted inside the hook.

[0007] As a preferred embodiment, the movable shell has symmetrically arranged movable grooves on the lower parts of both sides, and the outer end of the rotating shaft is rotatably connected to the same upper plate.

[0008] As a preferred embodiment, a first fixing rod is fixedly connected to the middle of the inner wall of the upper plate, and the first fixing rod is movably connected inside the movable groove.

[0009] As a preferred embodiment, a second fixing rod is fixedly connected to the lower inner side of the upper plate, and a self-locking plate is rotatably connected to the surface of the second fixing rod.

[0010] As a preferred embodiment, the self-locking plate has a groove at one end, and a locking block is fixedly connected to the bottom of one side of the fixing seat, the locking block being fitted into the inner wall of the groove.

[0011] As a preferred embodiment, the bottom end of the C-shaped frame is provided with a pin hole, and the pin hole is designed to be circular.

[0012] As a preferred embodiment, a positioning pin is fixedly installed at the top of the C-shaped frame, and the positioning pin is fitted into the inner wall of the pin hole.

[0013] As a preferred embodiment, the C-shaped frame has several strip grooves on its inner bottom side, and the strip grooves are of the same size.

[0014] As a preferred embodiment, anti-slip strips are fixedly installed on the inner walls of several of the strip grooves, and the top surface of the anti-slip strips is in contact with the bottom end of the battery body.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model achieves automatic engagement of the limiting frame and hook through the elastic force of the spring. When it is necessary to disassemble the stacked battery body, it is only necessary to pull the self-locking plate upward and rotate the upper plate upward to complete the unlocking, so that the upper battery body can be removed smoothly without the need for additional tools, which greatly improves the disassembly efficiency. Furthermore, through the cooperation of the groove and the locking block, it can only be opened by manually pulling it. Under natural or vibrational conditions, it will be locked and will not loosen, ensuring that the self-locking state is stable and reliable during non-human disassembly operations.

[0016] 2. This utility model uses pin holes and positioning pins to initially complete the docking, avoiding offset or misalignment during stacking, ensuring that the hooks and limit frames can be accurately aligned, and improving stacking efficiency. The anti-slip strip works in conjunction with the C-shaped frame, with the C-shaped frame wrapping around the battery body from the outside and the anti-slip strip directly contacting the bottom of the battery body from the inside, preventing the battery body from shaking or shifting, and ensuring the overall center of gravity is stable after stacking.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-6 This is the first embodiment of the present utility model, which provides a self-locking stacking bracket for energy storage batteries, including a battery body 1. Several C-shaped frames 2 are rectangularly distributed on the outer side of the battery body 1. The C-shaped frames 2 include a self-locking mechanism 3. A fixing seat 31 is fixedly connected to the upper outer side of the C-shaped frame 2 by bolts, and a hook 37 is fixedly connected to the lower outer side of the C-shaped frame 2 by bolts. The upper parts of both sides of the fixed base 31 are rotatably connected to the rotating shaft 32. The same movable shell 33 is movably connected to the opposite side of the rotating shaft 32. The movable shell 33 is movably connected to the inside of the movable shell 33. The bottom wall of the inner side of the limiting frame 35 is movably connected to the spring 36. The top of the spring 36 is fixedly connected to the inner wall of the movable shell 33. The top crossbar of the limiting frame 35 is embedded in the hook 37. The lower sides of the movable shell 33 are symmetrically provided with movable grooves 34, and the outer end of the rotating shaft 32 is rotatably connected to the same upper plate 38. A first fixing rod 39 is fixedly connected to the middle of the inner wall of the upper plate 38, and the first fixing rod 39 is movably connected to the inside of the movable groove 34; A second fixing rod 310 is fixedly connected to the lower inner side of the upper plate 38, and a self-locking plate 311 is rotatably connected to the surface of the second fixing rod 310. A groove 312 is provided at one end of the self-locking plate 311, and a locking block 313 is fixedly connected to the bottom side of the fixing seat 31. The locking block 313 is fitted into the inner wall of the groove 312.

[0021] During use, when it is necessary to disassemble the stacked battery body 1, first pull the self-locking plate 311 upward to rotate it around the second fixing rod 310, thereby disengaging the groove 312 from the locking block 313 and releasing the locking state of the self-locking plate 311 itself. Next, rotate the upper plate 38 upward. The upper plate 38 drives the first fixed rod 39 to move upward in the movable groove 34. During the upward movement of the first fixed rod 39, it will press against the movable shell 33, causing it to flip upward. When the movable shell 33 flips, it will squeeze the spring 36. The elastic force of the spring 36 will push the limit frame 35 to move upward, thereby causing the top crossbar of the limit frame 35 to disengage from the hook 37. At this time, the hook 37 of the upper battery is separated from the lower limit frame 35, and the upper battery body 1 can be smoothly removed, thereby unlocking. This design uses the elastic force of spring 36 to achieve automatic engagement between limit bracket 35 and hook 37. When it is necessary to disassemble the stacked battery body 1, simply push the self-locking plate 311 upward and rotate the upper plate 38 upward to unlock it, so that the upper battery body 1 can be removed smoothly without the need for additional tools, which greatly improves the disassembly efficiency. Furthermore, through the cooperation of groove 312 and locking block 313, it can only be opened by manual manipulation. Under natural or vibrational conditions, it will be locked and will not loosen, ensuring that the self-locking state is stable and reliable during non-human disassembly operations.

[0022] Reference Figures 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a pin hole 21 is provided at the bottom end of the C-shaped frame 2, and a positioning pin 22 is fixedly installed at the top end of the C-shaped frame 2, with the positioning pin 22 fitting into the inner wall of the pin hole 21.

[0023] During use, when the upper battery C-shaped frame 2 is stacked with the lower C-shaped frame 2, the pin hole 21 at the bottom of the upper C-shaped frame 2 will be pre-aligned with the positioning pin 22 at the top of the lower C-shaped frame 2 to complete the initial docking, avoid offset or misalignment during stacking, and ensure that the hook 37 and the limiting frame 35 can be accurately aligned, thereby improving stacking efficiency.

[0024] Several strip grooves 4 are provided on the bottom inner side of the C-shaped frame 2. Anti-slip strips 5 are fixedly installed on the inner wall of the several strip grooves 4. The top surface of the anti-slip strips 5 is in contact with the bottom end of the battery body 1.

[0025] During use, the anti-slip strip 5 works in conjunction with the C-shaped frame 2. The C-shaped frame 2 wraps around the battery body 1 from the outside, and the anti-slip strip 5 directly contacts the bottom of the battery body 1 from the inside, preventing the battery body 1 from shaking or shifting, and ensuring the overall center of gravity is stable after stacking.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
