[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Combine the following Figure 1-Figure 4 The output pole assembly provided in the embodiment of the utility model is described.

[0032] Specifically, the output pole assembly is used to connect to the bus bar 3, wherein the bus bar 3 can be a copper bar or an aluminum bar. The output pole assembly includes a cylinder structure 1 and a module output pole 2.

[0033] Among them, at least two long grooves 101 are arranged on the side wall of the cylinder structure 1 and distributed along the circumference of the cylinder. The long grooves 101 extend along the axial direction of the cylinder structure 1 and penetrate one end of the cylinder structure 1. The long grooves 101 are arranged along the wall thickness direction of the cylinder structure 1. For example, refer to Figure 2 As shown in the figure, the long slot 101 extends in the vertical direction and passes through the upper end of the cylinder structure 1. The portion between any two long slots 101 can be bent or broken to form an installation space between the two long slots 101 for the busbar 3 to pass through.

[0034] The cylinder structure 1 is also provided with a through hole 102 for the module output pole 2 to pass through, and the module output pole 2 and the busbar 3 are connected in the cylinder structure 1. Optionally, the module output pole 2 and the busbar 3 are connected by a threaded fastener.

[0035] The output pole assembly provided in the embodiment of the utility model is provided by setting a cylindrical structure 1 and setting a long groove 101 extending along the axial direction of the cylindrical structure 1 on the side wall thereof, the long groove 101 is set through along the wall thickness direction of the cylindrical structure 1 and the long groove 101 passes through one end of the cylindrical structure 1. During use, the bus 3 between the corresponding two long grooves 101 can be selectively bent or broken according to the orientation of the bus 3 to form an installation space for the bus 3 to pass through, the bus 3 enters into the cylindrical structure 1 through the installation space, the module output pole 2 enters into the cylindrical structure 1 through the through opening 102, and the bus 3 and the module output pole 2 are connected in the cylindrical structure 1.

[0036] In this way, the output pole assembly provided by the embodiment of the utility model can selectively bend or break the bus 3 between two long grooves 101 according to the actual position of the bus 3 by setting a long groove 101 on the side wall of the cylindrical structure 1, so as to form an installation space that adapts to the position of the bus 3 and allows the bus 3 to pass through, thereby realizing multi-angle access of the bus 3, solving the problem in the prior art that the installation port of the shell is fixed, resulting in the inconvenience of installing the bus 3, and achieving the effect of simplifying the bus structure and reducing the length of the bus.

[0037] In addition, refer to Figure 3 As shown, after the bus 3 passes through the installation space, the side walls on both sides of the installation space can limit the bus 3 to prevent the bus 3 from rotating, thereby preventing the threaded fasteners from loosening during the reciprocating rotation of the bus 3.

[0038] refer to Figure 2As shown, in some embodiments provided by the present invention, a groove 103 is provided at one end of the side wall of the long groove 101 close to the groove bottom of the long groove 101. Such a configuration can reduce the connection area between the part to be broken or the part to be bent of the cylinder structure 1 and the retained part of the cylinder structure 1, so that the part to be broken is easier to be broken, or the part to be bent is easier to be bent.

[0039] Furthermore, the two side walls of the long groove 101 are both provided with the grooves 103. Such a configuration can further make the part to be broken easier to be broken, or the part to be bent easier to be bent.

[0040] like Figure 2 As shown, in some embodiments provided by the present invention, the cylinder structure 1 is configured as a cylinder. In this way, the cylinder structure 1 is simple and easy to process and produce.

[0041] Of course, the cylinder structure 1 is not limited to being set as a cylinder. For example, in other embodiments provided by the present invention, the cylinder structure 1 is set as a polygonal cylinder. Optionally, the long groove 101 is set at least at each side edge of the polygonal cylinder.

[0042] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by the present invention, the through opening 102 is arranged on the side wall of the cylindrical structure 1. In this way, after the module output pole 2 passes through the through slot, the side walls on both sides of the through opening 102 can limit the module output pole 2 to prevent the module output pole 2 from rotating, thereby preventing the problem of the threaded fasteners loosening during the reciprocating rotation of the module output pole 2.

[0043] In some embodiments provided by the present invention, the output pole assembly further includes a mounting seat 4. The end of the cylindrical structure 1 that is away from the notch of the long slot 101 is connected to the mounting seat 4. For example, the structure of the battery module can constitute the mounting seat 4. Or the mounting seat 4 can also be a structure other than an independent battery module. During use, the mounting seat 4 is connected to the battery module. It should be noted that the notch of the long slot 101 refers to the end of the long slot 101 that passes through the end face of the mounting seat 4. For example, Figure 2 For example, the notch of the long slot 101 in the figure is arranged upward.

[0044] In this embodiment, the installation and fixation of the output pole assembly is facilitated by providing the installation seat 4.

[0045] In some embodiments provided by the present invention, the cylinder structure 1 and the mounting seat 4 are configured as an integral structure. For example, the cylinder structure 1 and the mounting seat 4 are configured as a plastic integral structure. In this configuration, the connection strength between the cylinder structure 1 and the mounting seat 4 is high, and the cylinder structure 1 has an insulating effect and will not transmit current, thereby reducing the probability of the busbar or the module output pole transmitting current to personnel through the cylinder structure 1.

[0046] Of course, the cylinder structure 1 and the mounting seat 4 are not limited to being set as an integral structure. For example, in other embodiments provided by the present invention, the cylinder structure 1 is connected to the mounting seat 4 through a connecting piece. Optionally, the connecting piece is set as a threaded fastener. Such a setting facilitates the disassembly of the cylinder structure 1. For example, the cylinder structure 1 can be easily disassembled and replaced after the structure of the cylinder structure 1 is damaged.

[0047] Of course, the cylinder structure 1 is not limited to being connected to the mounting seat 4 through a connector. For example, in other embodiments provided by the present invention, the cylinder structure 1 is snap-fitted to the mounting seat 4. Figure 2 and Figure 3 As shown, a slot 104 is provided at one end of the cylinder structure 1 close to the mounting seat 4, and the mounting seat 4 is clamped in the slot 104. With such a configuration, the cylinder structure 1 and the mounting seat 4 can be installed and removed without tools.

[0048] In some embodiments provided by the present invention, the busbar 3 and the module output pole 2 are both connected to the mounting seat 4. Specifically, threaded fasteners such as screws or bolts pass through the busbar 3 and the module output pole 2 and are threadedly connected to the mounting seat 4. By connecting both the busbar 3 and the module output pole 2 to the mounting seat 4, when the busbar 3 or the module output pole 2 is subjected to an action force, the action force is transmitted to the mounting seat 4 and borne by the mounting seat 4, reducing the conduction of the action force between the busbar 3 and the module output pole 2, so that the connection between the busbar 3 and the module output pole 2 is more stable.

[0049] In some embodiments provided by the utility model, the output pole assembly further includes a cover 5. The cover 5 is detachably covered on one end of the cylinder structure 1 away from the mounting seat 4. In this embodiment, by covering the cylinder structure 1 with the cover 5, the cylinder structure 1 can be sealed, reducing the probability of contact between the portion where the module output pole 2 and the bus 3 are connected and personnel. It can be understood that the portion other than the portion where the bus 3 and the module output pole 2 are connected is wrapped with an insulating outer skin.

[0050] Optionally, the cover body 5 includes a sleeve, which is sleeved on the outer side of an end of the cylinder structure 1 away from the mounting seat 4 .

[0051] refer to Figure 3As shown, in some embodiments provided by the present invention, a protrusion structure is provided on the outer wall of the cover body 5. By providing the protrusion structure, it is convenient for the operator to apply force to the cover body 5 to disassemble the cover body 5.
