Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery covers, and particularly relates to a cylindrical lithium battery cover assembly. Background Art

[0002] A lithium battery is a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high requirements for the environment. With the development of science and technology, lithium batteries have become the mainstream;

[0003] In the process of assembling existing lithium batteries, multiple cylindrical lithium batteries are placed side by side in a tray. Conductive sheets are arranged in the tray placement grooves to connect the multiple batteries. Then, the top of the lithium battery needs to be covered with a cover assembly to make the whole lithium battery stable. Conductive sheets are arranged in the limit grooves at the bottom of the cover, so as to facilitate the connection of multiple lithium batteries. However, in the actual use process, there are situations where the conductive sheets at the bottom of the cover are corroded and damaged, thus affecting the use effect of the lithium battery. The replacement operation of the conductive sheets inside the cover is troublesome, affecting the overall maintenance effect of the lithium battery. Therefore, new technical solutions need to be designed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a cylindrical lithium battery cover assembly to solve the technical problems that the conductive sheets at the bottom of the cover are corroded and damaged, thus affecting the use effect of the lithium battery, and the replacement operation of the conductive sheets inside the cover is troublesome.

[0005] To achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a cylindrical lithium battery cover assembly, including:

[0006] An end plate and a conductive mechanism;

[0007] A plurality of uniformly distributed through holes are opened at the top of the end plate, and a conductive mechanism is installed in the through holes;

[0008] The conductive mechanism includes a fixing block, the fixing block is inserted into the through hole, a conductive sheet is arranged at the bottom of the fixing block, springs are fixed on both sides of the top of the conductive sheet, and the top of the springs is connected to the fixing block. In the actual use process, when the conductive sheet needs to be repaired, maintained, or replaced, the separate conductive mechanism in the through hole is directly pulled out from the top of the end plate, and then the fixing block and the conductive sheet are directly taken out, thus facilitating the repair or replacement, improving the convenience of the operation. At the same time, in the use process, the function of the spring can ensure that the conductive sheet is tightly pressed against the top of the battery, thus ensuring the battery power-on effect and avoiding the situation of loosening and affecting the use effect of the lithium battery.

[0009] Preferably, a limiting slot is formed in the side wall of the fixing block, and a matching limiting plug is inserted into the inner cavity of the limiting slot. The two sides of the bottom of the limiting plug are respectively fixedly connected with the two springs. By inserting the limiting plug into the limiting slot, after the conductive mechanism is disassembled, the limiting plug can be directly pulled out of the limiting slot to disassemble the conductive sheet, which further improves the convenience of disassembling the conductive sheet and further improves the use effect.

[0010] Preferably, connecting plates are fixedly arranged on both sides of the top of the fixing block, and the connecting plates are connected with the end plate by bolts, so that the fixing block can be fixed, and at the same time, the conductive mechanism can be disassembled by removing the bolts, and the disassembly is convenient.

[0011] Preferably, a groove is formed in the bottom of the conductive sheet. The arrangement of the groove enables accurate limiting of the bald head at the top of the battery and ensures the stability of the battery.

[0012] Preferably, mounting plates are fixedly arranged on both side walls of the end plate, and mounting holes are formed in the surfaces of the mounting plates. The arrangement of the mounting holes facilitates the installation and fixation of the whole device.

[0013] Preferably, a rubber ring is fixedly arranged on one side wall of the end plate close to the lithium battery. The arrangement of the rubber ring ensures the sealing performance after the end plate is installed.

[0014] Preferably, a power-on wire is connected to one side wall of the conductive sheet, and the power-on wire is connected to the conductive sheet in a plug-in manner. Thus, when replacing the conductive sheet, the wire can be directly unplugged, and when replacing the new conductive sheet, the wire can be plugged in and used again.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, each separate conductive mechanism is inserted into the limiting hole of the cover plate, so that when the conductive sheet is rusty and affects the use, the conductive mechanism can be directly disassembled from the top of the cover plate without overall disassembly, which makes it convenient and fast to replace the conductive sheet in the conductive mechanism and improves the efficiency of maintenance and repair.

[0017] 2. In the present utility model, the conductive sheet is inserted into the fixing block by using the limiting plug, so that when disassembling the conductive sheet, the limiting plug can be directly pulled out, which further improves the convenience of replacing the conductive sheet and improves the operation efficiency of the staff.

At the same time, during the use process, the function of the spring 23 can ensure that the conductive sheet 22 is tightly pressed against the top of the battery, so as to ensure the battery power-on effect and avoid the situation that loosening affects the use effect of the lithium battery;

[0028] Furthermore, connecting plates 27 are fixed on both sides of the top of the fixing block 21, and the connecting plates 27 are connected to the end plate 1 through bolts 28, so that the fixing block 21 can be fixed, and at the same time, the conductive mechanism 2 can be disassembled by removing the bolts 28, and the disassembly is convenient;

[0029] Even further, a groove 24 is provided at the bottom of the conductive sheet 22. The setting of the groove 24 makes the positioning of the bald head on the top of the battery accurate and ensures the stability of the battery;

[0030] It is worth introducing that mounting plates 13 are fixed on both side walls of the end plate 1, and mounting holes 14 are provided on the surface of the mounting plates 13. The setting of the mounting holes 14 makes it convenient to install and fix the whole device;

[0032] As Figure 1 and Figure 3 shown; a limiting slot 25 is formed on the side wall of the fixing block 21, and a matching limiting plug 26 is inserted into the inner cavity of the limiting slot 25. The two sides of the bottom of the limiting plug 26 are respectively fixedly connected with two springs 23;

[0033] By inserting the limiting plug 26 into the limiting slot 25, after the conductive mechanism 2 is disassembled, the limiting plug 26 can be directly pulled out from the limiting slot 25 to disassemble the conductive sheet 22, which further improves the convenience of disassembling the conductive sheet 22 and further improves the use effect;
