Technical Field
[0001] This utility model relates to the field of battery cell support technology, and in particular to a battery cell support that can be quickly assembled. Background Technology
[0002] In the field of new energy, battery cells are the core components of energy storage and power supply. Their installation and fixation rely on special brackets to ensure structural stability and safety of use. As a result, battery cell bracket technology has become a key factor affecting battery pack assembly efficiency, space utilization and ease of operation and maintenance.
[0003] Currently, most battery cell brackets on the market are of the split type, which consists of two parts that are spliced together. During the splicing process, screwdrivers, wrenches and other tools are needed to tighten the bolts one by one, which is a cumbersome operation. Especially in the assembly of large-scale battery packs, this will significantly prolong the overall assembly time and reduce production efficiency. At the same time, the bolts are prone to loosening under long-term vibration, which may cause gaps between the battery cell and the bracket, resulting in the risk of battery cell displacement, collision or even short circuit, affecting the service life and safety performance of the battery pack. Therefore, this application proposes a battery cell bracket that can be spliced quickly. Utility Model Content

[0006] Optionally, the bottom of the upper ring is connected to the bottom of the lower ring, and the upper and lower rings have the same diameter and are coaxial. The mating groove is set as an arc-shaped L-shape, and the arc of the mating groove is coaxial with the lower ring. The mating plate is set as an arc-shaped L-shape, and the mating plate is coaxial with the upper ring. The width of the horizontal part of the mating plate matches the width of the vertical part of the mating groove, and the height of the horizontal part of the mating plate and the mating groove is the same.
[0007] Optionally, the limiting assembly includes a fixing tube, a limiting rod, an anti-detachment plate, and a first spring. The bottom of the lower ring has four through holes arranged in a circular array, each of which is connected to the center of the bottom of one of the four docking slots. The fixing tube is fixedly installed at the bottom of the lower ring and located at the through holes. The limiting rod is inserted through the through holes and into the fixing tube. The anti-detachment plate is located inside the fixing tube and fixedly sleeved on the limiting rod, with the top of the anti-detachment plate fitting against the bottom of the lower ring. The first spring is sleeved on the limiting rod, with both ends of the first spring fixedly connected to the bottom of the anti-detachment plate and the bottom of the inner wall of the fixing tube, respectively. The bottom of the fixing tube has an opening, with the bottom end of the limiting rod inserted through the opening. The bottom of the docking plate has a limiting groove that matches the top end of the limiting rod. When the horizontal part of the docking plate is rotated and inserted into the horizontal part of the docking slot, the top end of the limiting rod can be inserted into the limiting groove at the bottom of the docking plate.
[0008] Optionally, the unlocking component includes an inner ring and an outer ring. Each lower support plate has an arc-shaped slot inside. The inner ring is fitted into the slot on the four lower support plates, and the outer ring is fitted onto the outside of the four lower support plates. Four connecting blocks are installed in a circular array between the inner wall of the outer ring and the outer wall of the inner ring. The bottom ends of the four limiting rods are fixedly connected to the top of the inner ring. A vertical positioning rod is installed at the center of each of the four slots. Four positioning holes are evenly opened on the inner ring, and the four positioning holes on the inner ring are respectively fitted onto the corresponding positioning rods.

During assembly, simply align the four sets of L-shaped docking plates of the upper bracket with the vertical part of the L-shaped docking slot of the lower bracket and insert them. During insertion, the bottom of the docking plate will press the top of the limiting rod to move it downward. Then, rotate the upper bracket to make the docking plate slide into the horizontal part of the docking slot. When the docking plate is rotated until the limiting slot at its bottom is aligned with the top of the limiting rod, the limiting rod will automatically insert into the limiting slot at the bottom of the docking plate under the action of the first spring force, completing the locking. The whole process requires no additional tools, and the operation steps are simplified. Especially in large-scale battery pack assembly scenarios, it can significantly shorten the assembly time of a single bracket, greatly improve the overall production efficiency, and reduce manual operation costs and learning threshold.
[0012] The unlocking assembly consists of an inner ring, an outer ring, and a connecting block. When the bracket needs to be disassembled for cell inspection or replacement, simply press down on the outer ring. The connecting block will then move the inner ring down along the positioning rod. Simultaneously, the inner ring will pull the four sets of limit rods away from the limit groove of the docking plate. At this point, the upper bracket can be rotated in the opposite direction to complete the disassembly. The entire unlocking process requires no complicated tools, is convenient and efficient, and significantly reduces the time and labor costs of later battery pack maintenance, thus improving maintenance convenience.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figures 1-8 This utility model provides a technical solution: a quick-assembly battery cell support, including a lower support 1 and an upper support 2. The lower support 1 consists of a base plate 11, a lower support plate 12, and a lower ring 13. The lower support plate 12 is provided with four sets arranged in a circular array and vertically installed on the top of the base plate 11. The lower ring 13 is fixedly installed on the top of the four lower support plates 12. The upper support 2 consists of a top plate 21, an upper support plate 22, and an upper ring 23. The upper support plate 22 is provided with four sets arranged in a circular array and vertically installed on the bottom of the top plate 21. The upper ring 23 is fixedly installed on the bottom of the four upper support plates 22. Four sets of docking grooves 131 are formed in a circular array on the top of the lower ring 13, and four sets of docking plates 231 are installed in a circular array on the bottom of the upper ring 23. The four sets of docking plates 231 can be respectively engaged and connected in the corresponding docking grooves 131. Four sets of limiting components are installed at the bottom, and these four sets of limiting components can engage with the docking plates 231 in the corresponding docking slots 131. Unlocking components 3 are installed at the bottom of the four sets of limiting components. The unlocking components 3 can be lifted and set between the four sets of lower support plates 12. Through the docking and assembly of the upper bracket 2 and the lower bracket 1, in conjunction with the limiting components and unlocking components 3, a complete tool-free operation process of "assembly-locking-unlocking" is constructed from the structural design, reducing the complexity of operation. It also breaks the traditional bracket-dependent bolt tool fastening mode, providing core structural support for tool-free assembly and unlocking. At the same time, the symmetrical design of the lower bracket 1 and the upper bracket 2 can form a stable cell housing space. The lifting unlocking components 3 cleverly utilize the space between the lower support plates 12 to achieve functional integration without occupying the cell installation area, taking into account both structural compactness and practicality.
[0016] like Figure 1 , Figure 2 and Figure 3As shown, the bottom of the upper ring 23 is aligned with the bottom of the lower ring 13, and the upper ring 23 and the lower ring 13 have the same diameter and are coaxially arranged. The mating groove 131 is an arc-shaped L-shape, and the arc of the mating groove 131 is coaxial with that of the lower ring 13. The mating plate 231 is also an arc-shaped L-shape, and the mating plate 231 is coaxial with the upper ring 23. The width of the horizontal portion of the mating plate 231 matches the width of the vertical portion of the mating groove 131, and the heights of the horizontal portions of the mating plate 231 and the mating groove 131 are the same. The upper ring 231... The design of the upper bracket 2 and the lower bracket 13 having the same diameter and being coaxial ensures that the axes are precisely aligned when the upper bracket 2 and the lower bracket 1 are spliced, avoiding structural offset caused by eccentricity; the docking groove 131 and the docking plate 231 are both designed as arc-shaped L-shapes and are coaxial with the upper ring 23 and the lower ring 13 respectively, further improving the splicing positioning accuracy and reducing assembly errors. In addition, the size design of the docking plate 231 and the docking groove 131 allows the docking plate 231 to be smoothly inserted into the docking groove 131 and rotated, ensuring subsequent engagement and limiting.
[0017] like Figure 5 , Figure 6 and Figure 7As shown, the limiting assembly includes a fixing tube 132, a limiting rod 133, an anti-detachment plate 134, and a first spring 135. The bottom of the lower ring 13 has four through holes 136 arranged in a circular array. Each of the four through holes 136 communicates with the center of the bottom of one of the four mating grooves 131. The fixing tube 132 is fixedly installed at the bottom of the lower ring 13 and located at the through holes 136. The limiting rod 133 is inserted through the through holes 136 and the fixing tube 132. The anti-detachment plate 134 is located at the center of the fixing tube 135. The fixed tube 132 is fixedly sleeved on the limiting rod 133, and the top of the anti-detachment plate 134 is attached to the bottom of the lower ring 13. The first spring 135 is sleeved on the limiting rod 133, and the two ends of the first spring 135 are respectively fixedly connected to the bottom of the anti-detachment plate 134 and the bottom of the inner wall of the fixed tube 132. The bottom of the fixed tube 132 has an opening, and the bottom end of the limiting rod 133 is inserted through the opening. The bottom of the mating plate 231 has an opening that connects with the top of the limiting rod 133. When the horizontal portion of the mating plate 231 is rotated into the horizontal portion of the mating groove 131, the top end of the limiting rod 133 can be inserted into the limiting groove 232 at the bottom of the mating plate 231. With the help of the first spring 135, the limiting component allows the limiting rod 133 to automatically spring into the limiting groove 232 of the mating plate 231 when the mating plate 231 rotates to the horizontal portion of the mating groove 131, achieving automatic locking after splicing without the need for additional manual operation, thus simplifying assembly. The process is streamlined and assembly time is shortened. The limiting rod 133 passes through the through hole 136 and the fixing tube 132. The anti-detachment plate 134 can prevent it from falling out, ensuring that the limiting rod 133 is always in an effective working position. The top of the limiting rod 133 is adapted to the limiting groove 232. After being tightly locked, it can restrict the rotation and movement of the docking plate 231 and prevent the upper bracket 2 and the lower bracket 1 from becoming loose. The fixing tube 132 can also protect the limiting rod 133 and the first spring 135.
[0018] like Figure 5 , Figure 7 and Figure 8As shown, the unlocking component 3 includes an inner ring 31 and an outer ring 32. Each lower support plate 12 has an arc-shaped slot 121 inside. The inner ring 31 is fitted into the slots 121 on the four lower support plates 12, and the outer ring 32 is fitted onto the outside of the four lower support plates 12. Four connecting blocks 33 are installed in a circular array between the inner wall of the outer ring 32 and the outer wall of the inner ring 31. The bottom ends of the four limiting rods 133 are fixedly connected to the top of the inner ring 31. A vertical positioning rod 122 is installed at the center of each of the four slots 121. Four positioning holes 35 are evenly distributed on the inner ring 31, and each of the four positioning holes 35 is fitted onto the corresponding positioning rod 122. The bottom of the openings at both ends of each slot 121 is fixed to the bottom of the inner ring 31. Connected to the second spring 34, the unlocking component 3, through the linkage design of the inner ring 31, outer ring 32 and connecting block 33, can simultaneously drive the four limit rods 133 to move down and disengage from the limit groove 232 by pressing down the outer ring 32, thus unlocking the four sets of limit components at one time, avoiding the tedious operation of unlocking one by one, greatly improving the efficiency of bracket disassembly, and reducing the time cost of later battery cell maintenance or replacement. The positioning rod 122 can provide guidance for the lifting and lowering of the inner ring 31 to ensure its horizontal downward movement. The second spring 34 can push the inner ring 31 to reset after unlocking, preparing for the next splicing and locking. Moreover, the unlocking component 3 is cleverly integrated and installed in the space between the lower support plates 12, without occupying the battery cell area, simplifying the transmission path, reducing the number of parts, and reducing structural complexity and manufacturing costs.
[0019] like Figure 2 , Figure 3 and Figure 4 As shown, the bottom plate 11 has a bottom groove 110 at the top and the top plate 21 has a top groove 210 at the bottom. The bottom groove 110 and the top groove 210 have the same diameter and are coaxially arranged. A rotatable pressure plate 24 is provided in the top groove 210. The bottom groove 110 and the top groove 210 can provide a precise installation and positioning space for the battery cell, ensuring that the axis of the battery cell is aligned after installation. The pressure plate 24 in the top groove 210 can provide a certain degree of protection for the top of the battery cell when the upper bracket 2 is rotated.
[0020] like Figure 3 and Figure 4 As shown, the top groove 210 has an annular groove 211 inside, and the side wall of the pressure plate 24 has multiple hemispherical grooves in a circular array. Each hemispherical groove is provided with a rotatable ball 241, and the part of each ball 241 extending out of the hemispherical groove is located in the annular groove 211. This design allows the pressure plate 24 to rotate in the top groove 210, and the top of the installed battery cell presses against the bottom of the pressure plate 24. In this way, when the upper bracket 2 is rotated, the pressure plate 24 will not rotate with the upper bracket 2.
[0021] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
