[0002] At present, one of the connecting modes of the battery adapter pole and the top cover pole is that the adapter pole passes through the through hole of the top cover pole, and then the two are connected together through the seam welding connection mode, referring to the patent CN218242018U, which discloses that a through hole is formed on the conductor (i.e. the top cover pole), and a protrusion (i.e. the adapter pole) is arranged on the adapter piece (i.e. the current collecting member) and extends into the through hole of the conductor, and the protrusion and the conductor are connected by seam welding. For the battery, the above-mentioned seam welding connection mode has the following problems: 1. The assembly of the top cover pole and the adapter pole requires high precision, and the assembly gap is generally required to be less than 0.15mm, which increases the difficulty of assembly; 2. During assembly, the inner wall of the through hole of the top cover pole and the outer peripheral wall of the adapter pole are easy to interfere and produce metal chips; 3. In order to ensure the sealing effect, a sealing ring is usually arranged at the bottom of the adapter pole, and there is a risk of light leakage and ablation of the sealing ring during seam welding. Due to the above-mentioned risk of ablation of the sealing ring and the difficulty in controlling the assembly gap, the welding is easy to produce burst points, which reduces the welding efficiency.

[0003] Therefore, the existing technology has the problem of poor connection effect of the battery adapter pole and the top cover pole. SUMMARY

[0011] Further, the top surface of the adapter post has a second connecting protrusion, the assembly part is provided with an avoiding opening corresponding to the second connecting protrusion, and at least a part of the second connecting protrusion extends into the avoiding opening.

[0012] Further, the second connecting protrusion extends out of the mounting opening; and / or the top surface of the adapter post is coplanar with the top surface of the top cover post; and / or the assembly part covers the top surface of the top cover post entirely.

[0013] Further, the peripheral edge of the mounting opening has a mounting groove, and the assembly part is arranged in the mounting groove.

[0014] Further, the inner side wall of the accommodating cavity and the outer side wall of the adapter post have a mounting gap therebetween.

[0028] In order to solve the problem of poor connection effect between the battery adapter pole 20 and the top cover pole 10 in the prior art, the application provides a pole connecting structure.

[0029] As shown in Figures 1 to 5 The pole connecting structure in the application includes a top cover pole 10, an adapter pole 20, and an assembly part 30. The top cover pole 10 is arranged on the top cover sheet, and the top cover pole 10 has a receiving cavity 11 and a mounting opening 12 communicating with the receiving cavity 11. The adapter pole 20 is connected to the current collecting member, and at least a part of the adapter pole 20 is arranged in the receiving cavity 11. The mounting opening 12 is located on the side of the top cover pole 10 away from the current collecting member. The assembly part 30 is arranged on the side of the top cover pole 10 having the mounting opening 12 and covers at least a part of the mounting opening 12, and the assembly part 30 is connected to the top cover pole 10 and the adapter pole 20 respectively.

[0030] When the pole connecting structure in the application is used, since the pole connecting structure has the assembly part 30, and the top cover pole 10 and the adapter pole 20 can be connected through the assembly part 30, compared with the direct seam welding connection mode of the top cover pole 10 and the adapter pole 20 in the prior art, the connection between the top cover pole 10 and the adapter pole 20 in the application is more flexible. At the same time, the assembly part 30 and the top cover pole 10 can be welded, and the assembly part 30 and the adapter pole 20 can be welded. By this welding mode, the ablation of the sealing ring can be avoided, which can effectively protect the sealing ring. Moreover, by adding the assembly part 30, the welding difficulty of the original welding can be effectively reduced, the assembly gap requirement of the top cover pole and the adapter pole can be reduced, and the welding effect is improved. Therefore, the pole connecting structure in the application effectively solves the problem of poor connection effect between the battery adapter pole 20 and the top cover pole 10 in the prior art.

[0031] Moreover, for the welding mode between the assembly part 30 and the top cover pole 10, and the welding mode between the assembly part 30 and the adapter pole 20, the welding mode such as overlay welding and seam welding can be selected according to the actual production requirement. Therefore, the assembly part 30 in the application is made of metal material. In addition, the connection between the adapter pole and the current collecting member can be welding connection or integral molding, and the connection mode between the two is not limited.

[0032] Optionally, the mounting opening 12 is arranged on the top surface of the top cover pole 10, and at least a part of the assembly part 30 is arranged on the top surface of the top cover pole 10. Of course, according to the actual design requirement, the position of the mounting opening 12 and the arrangement mode of the adapter pole 20 in the receiving cavity 11 can be adaptively adjusted. In the following embodiments of the application, the axis of the top cover pole 10 and the axis of the adapter pole 20 are parallel to each other.

[0033] Preferably, the axis of the accommodating cavity 11, the axis of the top cover pole 10 and the axis of the adapter pole 20 are collinear.

[0034] Specifically, the inner side wall of the accommodating cavity 11 and the outer side wall of the adapter pole 20 have a mounting gap therebetween. By so arranging, not only can the adapter pole 20 be more easily mounted to the inside of the accommodating cavity 11, but also the metal chips generated during the assembly of the top cover pole 10 and the adapter pole 20 can be reduced, thereby improving the use performance of the battery. That is, in the present application, the peripheral edge of the mounting opening 12 and the accommodating cavity 11 are both larger than the peripheral edge of the adapter pole 20. Also, in the present application, the shape of the axial section of the accommodating cavity 11 can be circular, square, oval, hexagonal, octagonal, etc.

[0035] Preferably, the top surface of the top cover pole 10 and the top surface of the adapter pole 20 are parallel to each other, and the top surface and the bottom surface of the assembly piece 30 can be parallel to the top surface of the top cover pole 10 or can not be parallel to the top surface of the top cover pole 10, as long as the assembly piece 30 can be stably welded with the top cover pole 10 and the adapter pole 20.

[0036] In the embodiment as shown in Figure 2 , the top surface of the adapter pole 20 is coplanar with the top surface of the top cover pole 10. Also, the assembly piece 30 covers the entire top surface of the top cover pole 10. In the present embodiment, by so arranging, the overall shape of the pole connecting structure can be more regular, thereby facilitating the subsequent assembly of the battery.

[0037] In the embodiment as shown in Figure 3 , the top surface of the adapter pole 20 is below the top surface of the top cover pole 10. Also, the assembly piece 30 has a first connecting protrusion 31 on the side facing the top cover pole 10, and at least a portion of the first connecting protrusion 31 extends into the accommodating cavity 11 and connects with the adapter pole 20. In the present embodiment, by so arranging, the stability of the connection between the top cover pole 10 and the assembly piece 30 and between the adapter pole 20 and the assembly piece 30 can be effectively ensured, thereby effectively avoiding the falling off of the assembly piece 30, and further ensuring the use performance of the pole connecting structure.

[0038] In the embodiments as shown in Figure 4 and Figure 5 , the top surface of the adapter pole 20 has a second connecting protrusion 21, and the assembly piece 30 is provided with a avoiding opening 32 corresponding to the second connecting protrusion 21, and at least a portion of the second connecting protrusion 21 extends into the avoiding opening 32. In the present embodiment, by so arranging, the welding difficulty between the adapter pole 20 and the assembly piece 30 can be effectively reduced, thereby ensuring the assembly difficulty of the pole connecting structure.

[0039] In the embodiments as shown in Figure 4In the shown embodiment, the second connecting protrusion 21 extends out of the mounting opening 12. Optionally, the top surface of the adapter post 20 is coplanar with the top surface of the top cover post 10. Further optionally, the fitting 30 covers the entire top surface of the top cover post 10. Also, the top surface of the second connecting protrusion 21 can be parallel to the top surface of the fitting 30. Also, the cooperation between the second connecting protrusion 21 and the avoiding opening 32 can further ensure that the fitting 30 is easier and more accurate to install.

[0040] In the shown embodiment, the peripheral edge of the mounting opening 12 has a mounting groove 121, and the fitting 30 is arranged in the mounting groove 121. In this embodiment, by arranging in this way, the volume of the post connecting structure can be effectively reduced, thereby facilitating the miniaturization design of the post connecting structure.
