Description

Technical Field

[0001] This utility model relates to the field of battery cell support technology, specifically a battery cell support assembly. Background Technology

[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes, which is generally not used directly. It is the energy storage component of a rechargeable battery, and its quality directly determines the quality of the rechargeable battery. Battery cells are divided into three types: aluminum-cased cells, pouch cells, and cylindrical cells.

[0003] In some cases, cylindrical battery cells are used in series, requiring specific brackets to fix them together. However, existing bracket assemblies are generally of fixed size and can only support specific battery cells, thus limiting their applicability. Utility Model Content

[0004] The purpose of this invention is to provide a battery cell support assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery cell support assembly, including a base and a clamping plate. The upper end of the base has multiple mounting slots. Four support rods are arrayed and installed on the upper end of the base between the mounting slots. The upper ends of the four support rods contact the lower end of the clamping plate. The upper end of the clamping plate has multiple through slots. The longitudinal positions of the through slots and the mounting slots correspond to each other. Multiple grooves are arrayed on the sidewalls of both the mounting slots and the through slots. A transverse spring telescopic rod is installed inside each groove. A telescopic plate that slidably connects to the groove is installed at the other end of the spring telescopic rod. A compression arc plate is installed at the other end of the telescopic plate, with the end of the compression arc plate away from the spring telescopic rod having an arc-shaped surface.

[0006] Preferably, the upper end of the clamping plate and the lower end of the base are provided with two horizontal grooves and two vertical grooves, and the two horizontal grooves and two vertical grooves are arranged alternately.

[0007] Preferably, a first strap is installed in the transverse groove of the clamping plate and the base, and a second strap is installed in the longitudinal groove of the clamping plate and the base, with the two first straps and the two second straps being installed alternately.

[0008] Preferably, the upper end of the base has four ventilation holes arranged in an array, and the surface of the support rod has multiple ventilation slots arranged in an array. The ventilation holes are connected to the ventilation slots through the cavity inside the support rod.

[0009] Preferably, the base has multiple opening slots at its lower end, located outside the ventilation holes. A driven plug-in rod is slidably connected inside the opening slot. A lifting plate is installed at the lower end of the multiple driven plug-in rods. A fan unit is installed at the center of the lifting plate. The fan unit is connected to an external power source and is located directly below the multiple ventilation holes.

[0010] Preferably, the lower end of the lifting plate is equipped with multiple soft pads.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This battery cell support assembly works by inserting a cylindrical battery cell through a through slot into the mounting slot. The cylindrical battery cell pushes outward against multiple extrusion arc plates inside the through slot and mounting slot. The extrusion arc plates drive a telescopic plate to move inward into the groove and apply pressure to a spring telescopic rod. When the spring telescopic rod is compressed, it applies a reverse elastic force to the telescopic plate and the extrusion arc plates, causing the multiple extrusion arc plates to press the battery cell inward, thereby stabilizing the position of the battery cell. In conjunction with the clamping plate and base, the upper and lower ends of the battery cell are restricted. By installing multiple telescopic and adjustable extrusion arc plates, battery cells of different widths can be installed inside the mounting slot and through slot, enhancing the applicability of the support assembly.

[0013] 2. This battery cell support assembly has a lifting plate installed under the base. The lower end of the lifting plate is threaded to the outer metal shell. The fan unit inside the lifting plate is connected to an external power source. The fan unit will drive airflow through the ventilation holes into the cavity inside the support rod and exhaust it outward through multiple ventilation slots, thereby providing a certain heat dissipation effect for the multiple battery cells located outside the support rod.

[0023] like Figures 1 to 6As shown, the battery cell support assembly in this embodiment includes a base 1 and a clamping plate 2. The upper end of the base 1 has multiple mounting slots 6 arranged in a rectangular array. Four support rods 8 are arrayed between the mounting slots 6 on the upper end of the base 1. The four support rods 8 are located near the center of the upper end of the base 1 and are arranged in a rectangular array. The upper ends of the four support rods 8 contact the lower end of the clamping plate 2. The support rods 8 and the clamping plate 2 are detachably snap-fit ​​connected, connecting the clamping plate 2 and the base 1 together. The upper end of the clamping plate 2 has multiple through slots 5, whose longitudinal positions correspond to those of the mounting slots 6. The dimensions of the through slots are consistent with those of the mounting slot 6, and each through slot 5 is on the same vertical line as the center of the mounting slot 6. The dimensions of the through slot 5 are smaller than those of the mounting slot 6, while the dimensions of the through slot 5 are larger than those of the battery cell electrode post. The side walls of the mounting slot 6 and the through slot 5 are provided with multiple grooves 15 arranged in an array. A transverse spring telescopic rod 16 is installed inside the groove 15. The spring telescopic rod 16 will contract after being squeezed by external force, and the spring telescopic rod 16 has a certain strength. The other end of the spring telescopic rod 16 is equipped with a telescopic plate 17 that is slidably connected to the groove 15. The other end of the telescopic plate 17 is equipped with a compression arc plate 9. The end of the compression arc plate 9 away from the spring telescopic rod 16 is an arc-shaped surface.

[0024] Specifically, the upper end of the clamping plate 2 and the lower end of the base 1 are provided with two horizontal grooves 12 and two vertical grooves 13. The two horizontal grooves 12 and the two vertical grooves 13 are arranged alternately. A first strap 3 is installed in the horizontal grooves 12 of the clamping plate 2 and the base 1, and a second strap 4 is installed in the vertical grooves 13 of the clamping plate 2 and the base 1. The two first straps 3 and the two second straps 4 are arranged alternately. The connection strength between the clamping plate 2 and the base 1 can be enhanced by the two first straps 3 and the two second straps 4.

[0025] Furthermore, the upper end of the base 1 has four ventilation holes 10 arranged in an array, and the surface of the support rod 8 has multiple ventilation slots 11 arranged in an array. The ventilation holes 10 are connected to the ventilation slots 11 through the cavity 19 inside the support rod 8. The lower end of the base 1, located outside the ventilation holes 10, has multiple opening slots. A driven plug-in rod 18 is slidably connected inside the opening slot. The lower ends of the multiple driven plug-in rods 18 are jointly installed with a lifting plate 7. A fan unit 14 is installed at the center of the lifting plate 7. The fan unit 14 is connected to an external power supply and is located directly below the multiple ventilation holes 10. By setting the lifting plate 7 below the base 1, the lower end of the lifting plate 7 is connected to the external cavity 10. The metal shell is threaded together. The fan unit 14 inside the lifting plate 7 is connected to an external power source. The fan unit 14 will drive the airflow through the ventilation hole 10 into the cavity 19 inside the support rod 8, and exhaust it outward through multiple ventilation slots 11. This can play a certain role in heat dissipation for multiple battery cells located outside the support rod 8. It should be noted that during installation, the lifting plate 7 should first be fixed to the surface of the external metal shell with bolts. After fixing the position of the lifting plate 7, multiple battery cells are installed inside the base 1 in sequence. The first strap 3 and the second strap 4 are added. Finally, the mounting opening slot of the base 1 is connected to the driven plug-in rod 18.

[0026] Furthermore, multiple soft pads 20 are installed at the lower end of the lifting plate 7, which create a certain gap under the lifting plate 7, allowing air to circulate normally under the fan unit 14.

[0027] The method of use in this embodiment is as follows: insert the cylindrical battery cells into the mounting slot 6 at the upper end of the base 1 in sequence, then connect the clamping plate 2 to the support rod 8. The through slot 5 inside the clamping plate 2 can limit the electrode post at the upper end of the battery cell to prevent the battery cell from detaching from the through slot 5. Then add the first binding strap 3 and the second binding strap 4 to increase the structural strength of the bracket. Fix the position of the lifting plate 7 with bolts. Finally, connect the base 1 to the driven plug rod, and then connect the position of the base 1 to the outer metal shell with bolts to complete the assembly of the bracket and the battery cells.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
