[0001] The utility model relates to the technical field of battery cell brackets, in particular to a battery cell bracket for circular battery cells. Background Art

[0002] The battery cells of lithium batteries usually consist of a positive electrode plate, a negative electrode plate, a separator and an electrode lead-out structure. In circular lithium batteries, a winding structure is generally adopted, that is, the positive electrode plate, the separator and the negative electrode plate are stacked in sequence and then wound into a cylindrical shape for installation into a circular housing. In the production workshop, it is necessary to store the battery cells through a bracket.

[0003] In the process of using the existing battery cell brackets for circular battery cells, the size of the brackets is fixed and only suitable for supporting and fixing cylindrical battery cells of one specification. However, the specifications of battery cells are different, resulting in low applicability and utilization rate. Therefore, there is an urgent need for a battery cell bracket for circular battery cells to solve the above problems. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a battery cell bracket for circular battery cells.

A top plate is fixed at the top of the columns, and universal wheels are installed at the bottom of the columns. An adjusting component is arranged on the bearing plate. The adjusting component consists of a knob, a scale disk, a limiting block with an inclined surface at one end, a rotating shaft, four threaded grooves with opposite thread directions, a guide rod, a guide block, a concave cavity and a screw block. Pressing components are fixed at the bottom of the top plate and the bearing plate. The pressing component consists of an electric push rod, a connecting plate and a silica gel pad with a soft structure.

[0007] Preferably, the bearing plates are welded between the columns, the top plate is welded at the top of the columns, and the universal wheels are fixed at the bottom of the columns through bolts.

[0008] Preferably, the concave cavity is formed on the bearing plate. There are two groups of concave cavities. The rotating shaft is rotatably connected to one group of concave cavities. The knob penetrates through the bearing plate and is fixedly connected to one end of the rotating shaft.

[0009] Preferably, the threaded grooves are formed on the rotating shaft. The screw block is threadedly connected to the threaded grooves. The screw block matches the specifications of the concave cavity.

[0010] Preferably, the guide rod is welded in the other set of concave cavities, the guide block is slidably connected to the guide rod, and the guide block matches the specifications of the concave cavity.

[0013] The beneficial technical effects of the present utility model:

[0014] By designing the adjusting component and the pressing component, when supporting and fixing the cylindrical battery cell, the knob can be driven to rotate the rotating shaft, and then the screw block drives the limiting block to move under the action of the thread groove. The distance between the limiting blocks can be adjusted according to the diameter of the cylindrical battery cell, and the dial ensures the accuracy of the adjustment. Thus, cylindrical battery cells of different specifications can be supported and fixed.

[0021] To make the technical solutions of the present invention clearer and more definite to those skilled in the art, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. However, the implementation modes of the present invention are not limited thereto.

[0022] As Figures 1-4 shown, a battery cell bracket for circular battery cells provided in this embodiment includes four groups of vertical columns 1. A plurality of groups of bearing plates 2 are installed in an array along the vertical direction between the vertical columns 1. A top plate 3 is fixed to the top end of the vertical column 1, and a universal wheel 4 is installed at the bottom end of the vertical column 1. An adjusting component 5 is arranged on the bearing plate 2. The adjusting component 5 is composed of a knob 501, a dial 502, a limiting block 503 with an inclined surface at one end, a rotating shaft 504, four threaded grooves 506 with opposite thread directions, a guide rod 507, a guide block 508, a concave cavity 505 and a screw block 509. Pressing components 6 are fixed to the bottom ends of both the top plate 3 and the bearing plate 2. The pressing component 6 is composed of an electric push rod 603, a connecting plate 601 and a silicone pad 602 made of a soft structure.

[0023] The bearing plate 2 is welded between the vertical columns 1, the top plate 3 is welded to the top end of the vertical column 1, and the universal wheel 4 is fixed to the bottom end of the vertical column 1 by bolts. The universal wheel 4 facilitates the movement of the device.

[0024] The concave cavity 505 is formed on the bearing plate 2. There are two groups of concave cavities 505. The rotating shaft 504 is rotatably connected to one group of concave cavities 505. The knob 501 penetrates through the bearing plate 2 and is fixedly connected to one end of the rotating shaft 504. The knob 501 can drive the rotating shaft 504 to rotate.

[0025] The threaded groove 506 is formed on the rotating shaft 504. The screw block 509 is threadedly connected to the threaded groove 506. The screw block 509 matches the specifications of the concave cavity 505. During the rotation of the rotating shaft 504, the screw block 509 moves under the action of the threaded groove 506.

[0026] The guide rod 507 is welded in the other group of concave cavities 505. The guide block 508 is slidably connected to the guide rod 507. The guide block 508 matches the specifications of the concave cavity 505. The combination of the guide block 508 and the guide rod 507 can support the other end of the limiting block 503.

[0027] The limiting block 503 is fixed on the screw block 509 and the guiding block 508. The dial 502 is installed on the bearing plate 2 by screws. The screw block 509 drives the limiting block 503 to move, and the distance between the limiting blocks 503 can be adjusted according to the diameter of the cylindrical battery cell. At the same time, the dial 502 ensures the accuracy of the adjustment.

[0028] The fixed part of the electric push rod 603 is bolted to both the top plate 3 and the bearing plate 2. The output end of the electric push rod 603 is screwed to the connecting plate 601. The silica gel pad 602 is bonded to the bottom wall of the connecting plate 601. When movement is required, the electric push rod 603 pushes the connecting plate 601 downward so that the silica gel pad 602 contacts the cylindrical battery cell and is freely compressed according to the arc surface of the cylindrical battery cell, thereby tightly fixing it and ensuring the stability of the cylindrical battery cell during the movement.

[0029] The working principle of this device: During use, the device is moved to the working position through the universal wheels 4. Then, the knob 501 drives the rotating shaft 504 to rotate, so that the screw block 509 drives the limiting block 503 to move under the action of the thread groove 506. The distance between the limiting blocks 503 can be adjusted according to the diameter of the cylindrical battery cell. At the same time, the dial 502 ensures the accuracy of the adjustment, and thus different specifications of cylindrical battery cells can be supported and fixed. When movement is required, the electric push rod 603 pushes the connecting plate 601 downward so that the silica gel pad 602 contacts the cylindrical battery cell and is freely compressed according to the arc surface of the cylindrical battery cell, thereby tightly fixing it and ensuring the stability of the cylindrical battery cell during the movement, effectively improving the applicability and utilization rate of the device.
