[0033] Example

[0034] Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a structural schematic of the conductive component 100 provided in this embodiment. Figure 2 The diagram shown is an exploded view of the conductive component 100.

[0035] The conductive component 100 provided in this embodiment includes a conductive element 110, a first reinforcing element 120, and a second reinforcing element 130. The first reinforcing element 120 has a wiring groove 121, and the conductive element 110 is at least partially embedded in the wiring groove 121. The second reinforcing element 130 is detachably connected to the first reinforcing element 120 and covers the wiring groove 121. In this embodiment, the conductive component 100 is applied to a battery pack and is typically installed inside the battery pack housing. The conductive element 110 is a copper busbar and serves as the core component for transmitting current in the battery pack. Both the first reinforcing element 120 and the second reinforcing element 130 are made of insulating materials.

[0036] The conductive component 110 is embedded in the wiring groove 121. The first reinforcing component 120 and the second reinforcing component 130 protect the conductive component 110 from mechanical stress and chemical corrosion, ensuring its stability and reliability, enabling continuous and stable current transmission, and improving the electrical performance and electrical safety of the battery.

[0037] For ease of assembly, in this embodiment, the first reinforcing member 120 and the second reinforcing member 130 are detachably connected. Specifically, the second reinforcing member 130 is slidably engaged with the wiring groove 121 and is used to slide along the length of the wiring groove 121 under the action of external force to cover or open the wiring groove 121.

[0038] In actual assembly, after the conductive component 110 is embedded in the wiring groove 121, the second reinforcing component 130 is slid into one end of the wiring groove 121 and slid until it forms a cover over the wiring groove 121. When it is necessary to disassemble the conductive component 110, the second reinforcing component 130 is slid to open the wiring groove 121. Thanks to the sliding engagement between the second reinforcing component 130 and the wiring groove 121, the assembly and disassembly of the conductive component 100 are easy, facilitating quick assembly and disassembly for users in practical applications.

[0039] In order to improve the assembly efficiency of the first reinforcing member 120 and the second reinforcing member 130, realize automatic positioning in the assembly process, and improve assembly accuracy, in this embodiment, a limiting protrusion 131 is provided on the outer side wall of the second reinforcing member 130. The limiting protrusion 131 is used to abut against the first reinforcing member 120 when the second reinforcing member 130 slides to the cover wiring groove 121.

[0040] In this embodiment, when the second reinforcing member 130 slides toward the state of covering the wiring groove 121, the limiting protrusion 131 on the outer side wall of the second reinforcing member 130 gradually approaches the end wall of the first reinforcing member 120. When the limiting protrusion 131 moves to the end wall of the first reinforcing member 120 and abuts against it, the second reinforcing member 130 just completes the covering of the wiring groove 121, and the first reinforcing member 120 and the second reinforcing member 130 are assembled in place.

[0041] To further enhance the stability of the assembly structure of the first reinforcing member 120 and the second reinforcing member 130, in addition to the sliding fit between the second reinforcing member 130 and the first reinforcing member 120, the second reinforcing member 130 and the first reinforcing member 120 can also be connected by other connection methods, such as screw connection or snap-fit.

[0042] In another embodiment, the limiting protrusion 131 can be disposed at other parts of the second reinforcing member 130, and correspondingly, a supporting part for supporting the limiting protrusion 131 can be disposed at other positions on the first reinforcing member 120.

[0043] For example, the limiting protrusion 131 can be provided at one end of the second reinforcing member 130 that extends into the wiring groove 121, and a supporting part can be provided on the groove wall of the wiring groove 121. During the process of the second reinforcing member 130 sliding along the wiring groove 121, the supporting part is located on the movement path of the limiting protrusion 131. When the second reinforcing member 130 slides to cover the wiring groove 121, the supporting part just abuts against the limiting protrusion 131.

[0044] Please refer to the following: Figure 3 , Figure 3 The diagram shown is a structural schematic of the first reinforcing member 120.

[0045] In this embodiment, the cross-section of the wiring groove 121 is rectangular. The two sides of the groove opening along the width direction of the wiring groove 121 are folded inwards to form stop flanges 122. The second reinforcing member 130 is located between the stop flanges 122 and the bottom wall of the wiring groove 121. The stop flanges 122 limit the movement of the first reinforcing member 120, preventing it from dislodging from the opening of the wiring groove 121 and ensuring the stability of the assembly structure.

[0046] In another embodiment, the structure of the wiring groove 121 can be adjusted according to the actual application conditions. For example, its cross-section can be trapezoidal, triangular, etc.

[0047] Please refer to the following: Figure 4 and Figure 5 , Figure 4 The diagram shown is a structural schematic of the second reinforcing member 130. Figure 5 As shown Figure 4 An enlarged schematic diagram of region A in the middle.

[0048] In this embodiment, the second reinforcing member 130 includes a cover plate 132 and two side plates 133. The two side plates 133 are arranged opposite each other and are connected to the cover plate 132 at an angle. The conductive member 110 is located in the space enclosed by the cover plate 132, the bottom wall of the wiring groove 121 and the two side plates 133.

[0049] The second reinforcing member 130, formed by the angled connection between the cover plate 132 and the two side plates 133, has a stable and reliable structure. The cover plate 132 is supported by the two side plates 133, facilitating rapid assembly of the second reinforcing member 130 with the first reinforcing member 120. Furthermore, the two side plates 133 correspond significantly to the two side walls of the wiring groove 121, reliably limiting the second reinforcing member 130 within the wiring groove 121, thus ensuring the stability of the assembly structure of the second reinforcing member 130 and the first reinforcing member 120.

[0050] In fact, corresponding to the structure of the wiring groove 121, the two side plates 133 of the second reinforcing member 130 are perpendicular to the cover plate 132. When the second reinforcing member 130 covers the wiring groove 121, the two side plates 133 of the second reinforcing member 130, the cover plate 132, and the bottom wall of the wiring groove 121 together form a rectangular channel. In embodiments where the first wiring groove 121 has a different structure, the structure of the second reinforcing member 130 can be adjusted accordingly.

[0051] In order to reduce the contact area between the second reinforcing member 130 and the stop flange 122 on the first reinforcing member 120, and thus improve the smoothness of the sliding process, in this embodiment, the side of each of the two side plates 133 away from the bottom wall of the wiring groove 121 protrudes from the surface of the cover plate 132 to form a groove structure.

[0052] Understandably, the second reinforcing member 130 only contacts and slides relative to the first reinforcing member 120 through the side plate 133, and its cover plate 132 does not contact the stop fold 122, which improves the smoothness of the second reinforcing member 130 sliding in the wiring groove 121.

[0053] In fact, in order to further reduce the contact area between the second reinforcing member 130 and the first reinforcing member 120, in this embodiment, a notch 1221 is also provided on the stop fold 122 of the first reinforcing member 120.

[0054] To facilitate the entry of the second reinforcing member 130 into the wiring groove 121, in this embodiment, each of the two side plates 133 is provided with a guide slope 1331 at one end where it slides into the wiring groove 121. In practical applications, even if the second reinforcing member 130 is not fully aligned with the wiring groove 121 before entering it, it can still slide smoothly into the wiring groove 121 under the guidance of the guide slope 1331, thus successfully completing the assembly.

[0055] In this embodiment, the conductive component 110 has a first branch 111 and a second branch 112 connected at an angle. The first branch 111 is at least partially embedded in the wiring groove 121. In order to further improve safety, the surfaces of the first branch 111 and the second branch 112 are covered with an insulating protective layer.

[0056] Corresponding to the structure of the conductive member 110, in this embodiment, the second reinforcing member 130 has a first protective section 134 and a second protective section 135 connected at an angle. The first protective section 134 is composed of a cover plate 132 and two side plates 133, and covers the wiring groove 121. The second protective section 135 covers at least part of the second branch 112 on the side away from the first branch 111.

[0057] It is understandable that, since the first branch 111 and the second branch 112 of the conductive component 110 are connected at an angle, and the first branch 111 is located in the wiring groove 121, and the part of the second branch 112 that is away from the first branch 111 is at least partially covered by the second protective section 135, the movement of the conductive component 110 in the length direction of the wiring groove 121 is restricted by the first reinforcing member 120 and the second reinforcing member 130 when the assembly is completed, which further improves the stability and reliability of the overall structure.

[0058] In another embodiment, the structures of the first reinforcing member 120 and the second reinforcing member 130 can be adaptively adjusted according to the actual structure of the conductive member 110.

[0059] To further enhance the protection of the conductive component 110, in this embodiment, the conductive component 100 may also include a buffer 140, which is filled between the first branch 111 and the first reinforcing member 120 and / or the second reinforcing member 130. The buffer 140 may be made of a flexible insulating material.

[0060] To prevent the first reinforcing member 120 and the second reinforcing member 130 from enclosing the conductive member 110 and causing difficulty in heat dissipation of the conductive member 110, in this embodiment, a plurality of heat dissipation holes 123 are provided on the bottom wall of the wiring groove 121. The wiring groove 121 is connected to the outside through the heat dissipation holes 123, and the heat of the conductive member 110 can be dissipated smoothly through the heat dissipation holes 123 to avoid the conductive member 110 from getting too hot.

[0061] In summary, the conductive component 100 provided in this embodiment can improve the electrical performance and electrical safety of the battery pack.

[0062] In addition, this embodiment also provides a battery pack configured with the aforementioned conductive component 100. Benefiting from the beneficial effects of the conductive component 100, the battery pack provided in this embodiment has the characteristics of better electrical performance and higher safety.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
