[0030] The following is combined with Figures 1-4 This invention describes the electrode holder provided by the present invention.

[0031] Given the difficulties in connecting the battery module tabs and the resulting deformation in traditional technologies, please refer to [link to relevant documentation] for information on the problems with existing technologies. Figure 1 and Figure 3 This utility model provides an electrode holder, including a support frame 1, a support plate 2, and a partition plate 3.

[0032] The support frame 1 includes a first support block 11 and a second support block 12 arranged opposite to each other, forming the main frame. Both the first support block 11 and the second support block 12 are provided with connectors for connecting to the battery module. The connectors can be clips, bolts, or screws, as long as they allow for detachable connection to the battery module; this invention does not limit the specific type of connector.

[0033] A support plate 2 is positioned between the first support block 11 and the second support block 12. The support plate 2 has multiple slots 21 for the tabs to pass through. After passing through the slot 21, the tab is bent and abuts against the support plate 2. It is important to note that the width of the slot 21 is slightly greater than the thickness of the tab. After the tab is led out from the battery module, it passes vertically through the corresponding slot 21, then bends and flattens against the upper surface of the support plate 2. The support plate 2 provides a rigid support surface for the tab, allowing it to be quickly flattened through a rolling process after bending, eliminating twisting or wrinkles caused by the tab being suspended, thus ensuring flatness and consistency when the tab is soldered to the external circuitry.

[0034] A partition 3 is located on one side of the support plate 2, and each slot 21 has a partition 3 on both sides. Adjacent partitions 3 form independent isolation channels, and the tabs need to pass through the isolation channels before entering the slot 21. The isolation channels formed by the partitions 3 can separate adjacent tabs and prevent short circuits between tabs.

[0035] The tab bracket provided by this utility model provides a stable support structure formed by the support frame 1 and the support plate 2. The tab passes through the slot 21 on the support plate 2, bends, and abuts against the support plate 2. The support plate 2 facilitates the flattening of the tab, thereby ensuring the welding quality of the tab. Furthermore, the partition 3 separates the individual tabs, ensuring that they do not come into contact and cause a short circuit. The tab bracket provided by this utility model improves the efficiency and quality of battery module tab connections.

[0036] As mentioned earlier, the electrode tab needs to be bent and abut against the support plate 2 after passing through the slot 21. In practical applications, the electrode tab needs to be rolled flat. Considering that the rolling will put pressure on the support plate 2, in order to prevent the support plate 2 from deforming, in the technical solution provided by this utility model, at least one side of the partition plate 3 is provided with multiple reinforcing ribs 31, and each reinforcing rib 31 is arranged sequentially at intervals along the length direction. The reinforcing rib 31 structure can resist structural deformation, ensure the flatness of the support plate 2, and thus ensure the welding quality.

[0037] In one optional embodiment, the reinforcing ribs 31 are strip-shaped, each rib 31 is inclined, one end of each reinforcing rib 31 is connected to the partition plate 3, and the other end is connected to the support plate 2. Thus, by connecting the partition plate 3 and the support plate 2, a whole can be formed, and the deformation resistance of the support plate 2 is further improved through the reinforcing ribs 31 and the partition plate 3. In another optional embodiment, the reinforcing ribs 31 are triangular, with one side wall of each reinforcing rib 31 connected to the partition plate 3 and the other side wall connected to the support plate 2. Because the triangular reinforcing ribs 31 have two side walls that fit against the partition plate 3 and the support plate 2 respectively, the connection is more stable, and the support is also more stable, thus greatly improving the reinforcement effect on the support plate 2.

[0038] Please see Figure 1and Figure 4 In the technical solution provided by this utility model, the connector includes a metal insert 13 disposed on the first support block 11 and the second support block 12. The metal insert 13 is embedded in the first support block 11 and the second support block 12, and has a screw hole 14. The metal insert 13 can be integrally formed with the first support block 11 or the second support block 12 by injection molding, and its surface has a screw hole 14 for fastening to the side plate of the battery module with screws. The rigid material of the metal insert 13 can avoid the stripping problem caused by frequent tightening or vibration of traditional plastic threads, significantly improving the connection stability.

[0039] To prevent the tab bracket from wobbling during installation and connection, affecting installation efficiency and accuracy, the technical solution provided in this utility model includes two limiting grooves 15 on the side of the first support block 11 and the second support block 12 near the partition plate 3. The two limiting grooves 15 are respectively located near the two ends of the first support block 11 and the second support block 12. The limiting grooves 15 are designed to work in conjunction with external limiting fixtures. During battery module assembly, the limiting blocks of the limiting fixtures are embedded in the limiting grooves 15, and the tab bracket can be fixed by applying a pushing force on the other side of the support plate 2. This design ensures the stability of the tab bracket during installation, avoiding alignment deviations caused by external forces.

[0040] In addition, please see Figure 1 and Figure 2 Both the first support block 11 and the second support block 12 have multiple insulating sheet clearance slots 16 on the side near the partition 3. Each insulating sheet clearance slot 16 corresponds to the insulating sheet of the battery module, and the insulating sheet clearance slots 16 can prevent interference between the tab bracket and the insulating sheet. Furthermore, the insulating sheet clearance slots 16 include multiple clearance sub-slots 17 arranged sequentially at intervals along the height direction of the first support block 11 or the second support block 12. The clearance sub-slots 17 can increase the surface area of ​​the first support block 11 or the second support block 12 where they are located, thereby increasing the electrical clearance and creepage distance between the metal insert 13 and the battery module, further improving insulation protection capabilities and preventing leakage risks under high voltage environments.

[0041] Please see Figure 4 Furthermore, cylindrical positioning posts 18 are provided on the side of the first support block 11 and the second support block 12 away from the partition plate 3. The position of the positioning posts 18 corresponds to the positioning holes of the battery module cover. During installation, the positioning posts 18 are inserted into the positioning holes of the cover to achieve pre-positioning, ensuring precise alignment between the tabs and the cover, reducing cumulative assembly errors, and achieving insulation protection for the battery module tabs. In addition, welding identification holes 19 are provided on the side of the first support block 11 or the second support block 12 away from the partition plate 3 to facilitate camera positioning during automatic welding.

[0042] This utility model also provides a battery, including the above-described electrode holder. Based on this, this utility model also provides a vehicle, including the above-described battery. Since the main utility model feature lies in the electrode holder, the structure of the battery and the vehicle will not be described in detail.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
