Detailed implementation manners

[0034] Next, exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described herein.

[0035] Figure 1 It is a schematic structural diagram of an output pole assembly provided by an exemplary embodiment of the present application. As Figure 1 shown, the battery provided by the embodiment of the present application may include a housing, a battery cell, a plurality of busbars, and an output pole assembly 200. The battery cell is disposed in the housing, the plurality of busbars are connected to the pole posts of the battery cell, the busbars can transmit current between the battery cells, the output pole assembly 200 is connected to the housing, and part of the busbars are disposed in the output pole assembly 200. The output pole assembly 200 can protect part of the busbars.

[0036] As Figure 1 shown, the output pole assembly 200 provided by the embodiment of the present application may include an end plate 210 and an output pole support 100. The end plate 210 is connected to the aforementioned housing, and the output pole support 100 is assembled on the end plate 210 to ensure that the output pole support 100 can be stable for a long time during operation.

[0037] Specifically, Figure 2 is a schematic structural diagram of an end plate provided by an exemplary embodiment of the present application. Figure 3 is a schematic structural diagram of an output pole support provided by an exemplary embodiment of the present application from a first perspective. As Figure 2 and Figure 3 shown, the end plate 210 is provided with a mounting groove 212. The output pole support 100 may include a support base 110, and the support base 110 is assembled in the mounting groove 212. The mounting groove 212 can play a role in mounting and positioning, facilitating the quick determination of the mounting position of the support base 110.

[0038] As Figure 2 and Figure 3 shown, the end plate 210 is further provided with a clamping cavity 211. Generally, the opening of the clamping cavity 211 corresponds to the inner cavity of the mounting groove 212. Correspondingly, the output pole support 100 may further include a protrusion 120 and an elastic body 130. The protrusion 120 is connected to the bottom of the support base 110, and the elastic body 130 is connected to the protrusion 120.

[0039] During the actual assembly process, the protrusion 120 can extend into the clamping cavity 211, thereby guiding the elastic body 130 into the clamping cavity 211. That is to say, the protrusion 120 can not only serve as an installation carrier for the elastic body 130 but also be used to guide the elastic body 130 into the clamping cavity 211.

[0040] When the protrusion 120 extends into the clamping cavity 211, the elastic body 130 undergoes elastic deformation. Under the action of the restoring force, the elastic body 130 can elastically press against the inner wall of the clamping cavity 211. In this way, it can ensure the relative fixation between the output pole support 100 and the end plate 210, making it difficult for the output pole support 100 to detach from the end plate 210, effectively improving the assembly stability.

[0041] It should be understood that when it is necessary to disassemble the output pole support 100 from the end plate 210, by operating the support base 110, the elastic body 130 undergoes greater elastic deformation, so that a gap is generated between the protrusion 120 and the inner wall of the clamping cavity 211. In this way, the protrusion 120 can smoothly move out of the clamping cavity 211, and thus the output pole support 100 can be quickly removed from the end plate 210.

[0042] It should be understood that the output pole support 100, output pole assembly 200 and battery provided in the embodiment of the present application, during the assembly process, the elastomer 130 elastically abuts against the inner wall of the holding cavity 211, so that the output pole support 100 is quickly and stably assembled on the end plate 210. During the disassembly process, the elastomer 130 is deformed to a greater extent, so that the protrusion 120 can be smoothly moved out of the holding cavity 211, and the output pole support 100 can be quickly removed from the end plate 210. In this way, the disassembly and assembly process of the output pole support 100 can be effectively simplified, and the disassembly and assembly efficiency can be effectively improved.

[0043] In one embodiment, the cross section of the holding cavity 211 may be rectangular, triangular, polygonal, etc.

[0044] In one embodiment, a buckle can be provided on the inner wall of the holding cavity 211 , which not only facilitates the snapping of the elastic body 130 , but also improves the stability of the elastic body 130 after assembly, so that the elastic body 130 is not easily separated from the holding cavity 211 .

[0045] In one embodiment, the output electrode support member 100 can be applied to the positive electrode of a battery cell, and can also be applied to the negative electrode of a battery cell.

[0046] Figure 4 This is a schematic diagram of the structure of the output pole support provided by an exemplary embodiment of the present application at a second viewing angle. Figure 4 As shown, the elastomer 130 may include an elastic strip 131, one end of which is connected to the side wall of the protrusion 120, and the elastic strip 131 is inclined relative to the side wall of the protrusion 120 in the direction close to the support seat 110. In this way, in the process of the protrusion extending into the holding cavity 211, the inclined elastic strip 131 can more easily abut against the inner wall of the holding cavity 211, that is, when the protrusion 120 extends a shorter distance, the purpose of the elastomer 130 elastically abutting against the inner wall of the holding cavity 211 can be achieved, which can effectively save assembly time and improve assembly efficiency.

[0047] In one embodiment, the inclination angle between the elastic strip 131 and the sidewall of the protrusion 120 is an acute angle.

[0048] like Figure 4 As shown, the elastic body 130 may further include a barb portion 132, which is connected to the end of the elastic strip 131 away from the protrusion 120, and the barb portion 132 is connected to the elastic strip 131 at an angle. In this way, after the elastic strip 131 enters the retaining cavity 211, the barb portion 132 can increase the contact area with the inner wall of the retaining cavity 211, thereby allowing the output pole support member 100 to be more stably assembled on the end plate 210.

[0049] like Figure 4As shown, the included angle between the side wall of the barb portion 132 and the side wall of the elastic strip 131 is an obtuse angle, and the side wall of the barb portion 132 is arranged parallel to the side wall of the protrusion 120. In this way, during the process of the protrusion 120 extending into the clamping cavity 211 along its own length direction, the barb portion 132 can extend into the clamping cavity 211 along the length direction of the protrusion 120 synchronously with the protrusion 120. When the barb portion 132 elastically abuts against the inner wall of the clamping cavity 211, the protrusion 120 will not tilt relative to the barb portion 132. Therefore, after assembly, the situation of tilting and jamming of the output pole support member 100 relative to the end plate 210 can be avoided, which is beneficial to quickly disassembling the output pole support member 100 from the end plate 210 subsequently.

[0050] As Figure 3 shown, the number of the elastic bodies 130 is two, and the two elastic bodies 130 are spaced apart and distributed on the protrusion 120. After the protrusion 120 extends into the clamping cavity 211, both of the two elastic bodies 130 can elastically abut against the inner wall of the clamping cavity 211. In this way, the assembly stability of the output pole support member 100 on the end plate 210 can be improved, and the probability of the output pole support member 100 detaching from the end plate 210 can be further reduced.

[0051] Figure 5 is Figure 2 the enlarged schematic view of the position A in Figure 2 、 Figure 3 and Figure 5 shown, the installation groove 212 is recessed and opened at the top of the end plate 210. The side wall of the installation groove 212 protrudes and extends inwardly with a first extension portion 213 and a second extension portion 214. The first extension portion 213 and the second extension portion 214 are relatively spaced apart. A first guiding groove 215 extending outwardly and recessed is formed between the first extension portion 213 and the bottom wall of the installation groove 212. A second guiding groove 216 extending outwardly and recessed is formed between the second extension portion 214 and the bottom wall of the installation groove 212; correspondingly, first guiding bodies 140 and second guiding bodies 150 are protrudingly provided on both side walls of the support seat 110. The first guiding body 140 cooperates with the first guiding groove 215, and the second guiding body 150 cooperates with the second guiding groove 216, so as to facilitate quickly snapping the support seat 110 into the installation groove 212.

[0052] Specifically, during the assembly process, first align the first guiding body 140 with the first guiding groove 215, and then move the support seat 110 so that the first guiding body 140 cooperates with the first guiding groove 215. During the process of the first guiding body 140 cooperating with the first guiding groove 215, the second guiding body 150 cooperates with the second guiding groove 216. In this way, under the combined guiding action of the first guiding groove 215 and the second guiding groove 216, the support seat 110 can be accurately snapped into the installation groove 212, effectively improving the assembly efficiency.

[0053] In one embodiment, during the assembly process, the second guiding body 150 can also be aligned with the second guiding groove 216 first, and then the support base 110 is moved so that the second guiding body 150 cooperates with the second guiding groove 216. During the cooperation between the second guiding body 150 and the second guiding groove 216, the first guiding body 140 cooperates with the first guiding groove 215, realizing the function of accurately and quickly snapping the support base 110 into the installation groove 212.

[0054] As Figure 3 shown, the length of the second guiding body 150 is greater than the length of the first guiding body 140, and during the cooperation between the second guiding body 150 and the second guiding groove 216, part of the second guiding body 150 is always located outside the second guiding groove 216. In this way, during the guiding process, the moving direction of the second guiding body 150 can be adjusted in a timely manner according to the part located outside the second guiding groove 216, thereby avoiding the situation of skew and jamming of the support base 110 during the assembly into the installation groove 212, and effectively improving the assembly accuracy and assembly efficiency.

[0055] In one embodiment, it can also be that the length of the first guiding body 140 is greater than the length of the second guiding body 150, and part of the first guiding body 140 is located outside the first guiding groove 215.

[0056] As Figure 3 shown, the extending direction of the first guiding body 140 coincides with the extending direction of the second guiding body 150. In this way, when the first guiding body 140 enters the first guiding groove 215, the second guiding body 150 can enter the second guiding groove 216 smoothly, and it is not easy for the second guiding body 150 to be stuck outside the second guiding groove 216, which is beneficial to more smoothly assembling the support base 110 into the installation groove 212; or when the second guiding body 150 enters the second guiding groove 216, the first guiding body 140 can enter the first guiding groove 215 smoothly, and it is not easy for the first guiding body 140 to be stuck outside the first guiding groove 215.
