Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a busbar tooling and an energy storage product. Background Technology

[0002] Energy storage products are devices that convert external energy into electrical energy and store it internally, providing power to external electrical devices (such as new energy vehicles and portable electronic devices) when needed. Energy storage products are widely used in daily life, greatly enhancing convenience and enriching people's lives. However, in recent years, with the use of high-power applications, the power consumption of energy storage products has increased dramatically. When the energy storage in an electrical device is insufficient, the user can recharge the device. Generally, energy storage products consist of multiple battery modules, connected in series and parallel via busbars. Specifically, the busbars and battery modules can be connected by laser welding. Therefore, busbar welding has become a key technology. Typically, the busbar needs to be placed before laser welding, and its positioning is crucial. If the busbar is misaligned, the laser welding point may be misaligned, resulting in poor welding; if the laser hits the battery module, it can cause safety issues such as fire.

[0003] In the process of developing this application, the applicant discovered that currently, when assembling a busbar into a battery module, there is no effective tooling for positioning the busbar, and the busbar is prone to wobbling after placement, causing welding deviations.

[0030] Please see Figures 1 to 4 The busbar fixture 100 provided in this embodiment includes a positioning plate 10 and a positioning pin 20. The positioning plate 10 is provided with a positioning hole 11 for positioning and exposing the busbar 300. The positioning plate 10 is provided with a mounting hole 12, and the positioning pin 20 is disposed in the mounting hole 12. The positioning pin 20 is movably connected to the positioning plate 10 and can abut against the side wall 202 of the battery module 200 connected to the busbar 300. With this busbar fixture 100, when the busbar 300 is placed on the battery module 200, the busbar 300 can be positioned through the positioning hole 11 on the positioning plate 10, reducing the risk of the busbar 300 swinging. The busbar 300 is exposed at the positioning hole 11, which facilitates the subsequent welding connection between the busbar 300 and the battery module 200. In addition, due to the setting of the positioning pin 20, when the positioning pin 20 abuts against the side wall 202 of the battery module 200, it not only facilitates the positioning between the positioning plate 10 and the battery module 200, but also improves the stability of the positioning plate 10 relative to the battery module 200, further reducing the risk of the busbar 300 swinging at the positioning hole 11, and improving assembly, production efficiency and safety reliability.

[0031] The battery module 200 has a head 201, which is the location of the terminal post, and is connected to the busbar 300. The battery module 200 also has a tail (not shown) opposite to the head 201, and the sidewall 202 of the battery module 200 is located between the head 201 and the tail.

[0032] In some embodiments, the number of positioning holes 11 is multiple, and each positioning hole 11 is used for positioning and exposing a busbar 300. The specific number and position of the positioning holes 11 can be reasonably set according to the actual needs of the battery module 200.

[0033] In some embodiments, the busbar fixture 100 further includes a first fastener 30, which is locked to the positioning plate 10. The first fastener 30 passes through the mounting hole 12 and through the positioning pin 20. The positioning pin 20 is movably connected to the first fastener 30, providing a specific implementation method for the movable connection between the positioning pin 20 and the positioning plate 10.

[0034] The first fastener 30 is a screw, bolt, stud, or other fastener with a fastening function. For example, the first fastener 30 can be an M3*25 cylindrical hexagonal socket head cap screw.

[0035] In some embodiments, the positioning pin 20 is provided with a sliding hole 221, and the first fastener 30 passes through the sliding hole 221. The positioning pin 20 is movably connected to the first fastener 30 through the sliding hole 221. When the positioning pin 20 is moved, the positioning pin 20 slides relative to the first fastener 30 through the sliding hole 221, thereby enabling the positioning pin 20 to abut against the side wall 202 of the battery module 200, and also enabling the positioning pin 20 to eliminate the restriction on the battery module 200.

[0036] In some embodiments, the positioning pin 20 includes a connecting actuating part 21 and an abutting part 22. A sliding hole 221 is disposed in the abutting part 22, and the abutting part 22 is used to abut against the side wall 202 of the battery module 200. With this arrangement, when the actuating part 21 is turned, the positioning pin 20 can move relative to the first fastener 30 through the sliding hole 221, thereby enabling the positioning pin 20 to move relative to the positioning plate 10. This allows the abutting part 22 in the positioning pin 20 to abut against the side wall 202 of the battery module 200, and also allows the abutting part 22 to eliminate the restriction on the battery module 200.

[0037] In some embodiments, the mounting hole 12 is a waist-shaped hole, and the first fastener 30 passes through the waist-shaped hole along the width direction D1; along the width direction D1 of the waist-shaped hole, the actuating part 21 protrudes from the abutting part 22, thereby increasing the size of the actuating part 21 and facilitating the actuation of the positioning pin 20.

[0038] The length direction of the waist-shaped hole refers to the direction along the two straight sections of the waist-shaped hole, and the width direction D1 of the waist-shaped hole is perpendicular to the length direction of the waist-shaped hole.

[0039] In some embodiments, the number of mounting holes 12 is multiple, the number of positioning pins 20 is multiple, one positioning pin 20 is disposed in one positioning hole 11, and multiple positioning pins 20 are distributed on the positioning plate 10 so that the multiple positioning pins 20 can abut against the periphery of the battery module 200. Multiple sidewalls 202 of the battery module 200 form the periphery of the battery module 200. For example, if the battery module 200 has four sidewalls, then the four sidewalls of the battery module 200 form the periphery of the battery module 200. For example, the number of positioning pins 20 is six, wherein two positioning pins 20 are disposed opposite each other on two short sides of the positioning plate 10, two positioning pins 20 are distributed on one long side of the positioning plate 10, and two positioning pins 20 are distributed on the other long side of the positioning plate 10. With this setting, when the positioning pin 20 abuts against the periphery of the battery module 200, the fixing stability of the positioning pin 20 to the battery module 200 is further improved, and the positioning stability of the positioning hole 11 on the positioning plate 10 to the busbar is improved.

[0040] It is understood that when there are multiple positioning pins 20, there are also multiple first fasteners 30, and each first fastener 30 passes through a positioning pin 20.

[0041] In some embodiments, the busbar fixture 100 further includes a second fastener 40, which is used to lock the positioning plate 10 to the battery module 200. The setting of the second fastener 40 improves the stability of the busbar fixture assembled to the battery module 200 and improves the positioning stability of the positioning hole 11 on the positioning plate 10 for the busbar 300.

[0042] The second fastener 40 is a screw, bolt, stud, or other fastener with a fastening function. For example, the second fastener 40 can be an M6*12 screw.

[0043] In some embodiments, the number of the second fasteners 40 is at least two, and at least two of the second fasteners 40 are distributed on the positioning plate 10.

[0044] This application also provides an embodiment of an energy storage product 1000, such as... Figure 3 and Figure 4 As shown, the energy storage product 1000 includes a battery module 200, a busbar 300, and the aforementioned busbar fixture 100. For the specific structure and function of the busbar fixture 100, please refer to the above embodiments, which will not be repeated here. The positioning plate 10 of the busbar fixture 100 is stacked on the head 201 of the battery module 200, the busbar 300 is positioned in the positioning hole 11, and the positioning pin 20 abuts against the side wall 202 of the battery module 200.
