[0055] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0056] In this application, the term "lateral" refers to a direction generally perpendicular to the central axis of a column.

[0057] Figure 1 A vehicle 1 according to an embodiment of the present application is schematically shown. A plurality of battery pack assemblies 11 and a charging interface 10 are provided in the vehicle 1. A bus assembly 2 for the vehicle is connected between the battery pack assembly 11 and the charging interface 10. It should be understood that the bus assembly 2 can also be used to electrically connect other electrical components of the vehicle 1, for example, between the battery pack assembly 11 and the motor (not shown in the figure).

[0058] According to the following Figures 2 to 9 The busbar assembly 2 will be described.

[0059] Figure 2 The busbar assembly 2 according to the first embodiment of the present application is schematically shown. Figure 2 As shown, the busbar assembly 2 includes a first busbar 21 and a second busbar 22. Figure 4 As shown, the first busbar 21 has a first connection portion 211, and a connection head 23 is mounted on the first connection portion 211. Figure 5 As shown, the second busbar 22 has a second connection portion 222. The second connection portion 222 matches the first connection portion 211, and a connection slot 24 is installed on the second connection portion 222. The connector 23 is suitable for being plugged into the connection slot 24 to electrically connect the first busbar 21 and the second busbar 22.

[0060] When the busbar assembly 2 of the present application is assembled into the vehicle 1, the first busbar 21 and the second busbar 22 do not need to be pre-connected into a predetermined shape, but one of the first busbar 21 and the second busbar 22 can be installed first according to the actual situation, and then the other can be installed. In this way, the busbar assembly 2 can be prevented from interfering with other components of the vehicle 1, so that the busbar assembly 2 can be assembled smoothly. For example, Fig. 9As shown, during the assembly of the battery pack assembly, the battery cell 13 protrudes from the lower shell 12; the substantially "L"-shaped busbar assembly 2 (including the "L"-shaped bent first busbar 21 and the straight second busbar 22) needs to be configured such that one end is connected to the inner wall of the lower shell 12 (i.e., between the lower shell 12 and the battery cell 13), and the other end is above the battery cell 13. In this way, the second busbar 22 can first be vertically installed at a predetermined position on the inner wall of the lower shell 12, so that the second connecting portion 222 is outside the lower shell 12 and the connecting groove 24 faces the outside of the lower shell 12; then the battery cell 13 is installed in the lower shell 12; finally, the "L"-shaped first busbar 21 is installed in accordance with the battery cell 13, and the connector 23 of the first busbar 21 is inserted into the connecting groove 24. During the entire assembly process, the first busbar 21 , the second busbar 22 and the battery cell 13 do not interfere with each other; and no welding operation is required to prevent damage to the battery cell 13 .

[0061] It should be understood that, if necessary, the connector 23 may be first inserted into the connecting groove 24 to form the first bus 21 and the second bus 22 into a whole, and then the bus assembly 2 may be assembled as a whole.

[0062] According to the busbar assembly 2 of the present application, the connector 23 is detachably connected to the connecting slot 24, so that it is convenient to replace or maintain any one of the first busbar 21 and the second busbar 22 according to actual conditions.

[0063] In addition, according to the busbar assembly 2 of the present application, the first busbar 21 and the second busbar 22 can have a shorter length, which helps prevent the first busbar 21 and the second busbar 22 from being deformed, thereby reducing the difficulty of manufacturing these busbars and facilitating the packaging and transportation of the busbars. At the assembly site, the first busbar 21 and the second busbar 22 are assembled as needed.

[0064] It should be understood that the connector 23 can be arranged at the end of the first busbar 21, or at the middle or other position of the first busbar 21 according to actual conditions; the same is true for the connecting groove 24. For simplicity, in this application, the busbar assembly 2 is described by taking the example that the connector 23 is arranged at the end of the first busbar 21 and the connecting groove 24 is also arranged at the end of the second busbar 22.

[0065] In one embodiment, the first busbar 21, the second busbar 22, the connector 23 and the connection slot 24 are all made of copper. In this way, after the connector 23 is plugged into the connection slot 24, the electrical connection between the first busbar 21 and the second busbar 22 is naturally achieved. It should be understood that the first busbar 21, the second busbar 22, the connector 23 and the connection slot 24 can also be made of other metal materials with good electrical conductivity according to actual conditions. In addition, the materials of the first busbar 21 and the second busbar 22 and the materials of the connector 23 and the connection slot 24 can also be different.

[0066] In one embodiment, a mounting hole (not shown in the figure) is constructed on the first connecting portion 211. The connector 23 is an independently formed component and is fixedly installed in the mounting hole. For example, the connector 23 can be welded or threaded into the mounting hole. In other embodiments, the connector 23 can also be interference fit into the mounting hole. In other embodiments, the connector 23 can also be integrally formed with the first bus 21; for example, the connector 23 is machined on the first bus 21. Similar to the connector 23, the connecting groove 24 can also be an independently formed component and installed on the second bus 22, or it can be integrally formed with the second bus 22. For simplicity, in this application, the bus assembly 2 is described by taking the connector 23 and the connecting groove 24 as independently formed components as an example.

[0067] Alternatively, if Figure 4 As shown, the first connecting portion 211 is configured with a first connecting surface 213, and the connecting head 23 protrudes from the first connecting surface 213. Figure 5 As shown, the second connecting portion 222 is configured with a second connecting surface 223 that matches the first connecting surface 213, and the connecting groove 24 opens on the second connecting surface 223. After the connector 23 is inserted into the connecting groove 24, the first connecting surface 213 is in close contact with the second connecting surface 223 (as shown in FIG. Figure 2 As shown). According to this structure, the contact area between the first connection portion 211 and the second connection portion 222 is large, which helps to improve the connection stability between the first busbar 21 and the second busbar 22. In addition, after the first connection surface 213 and the second connection surface 223 are in close contact, it is difficult for the external environment to contact the connector 23 and the connection groove 24, which protects the connector 23 and the connection groove 24 and also helps to improve the connection stability between the first busbar 21 and the second busbar 22.

[0068] Optionally, Figure 4 As shown in FIG. 2 , a first insulating layer 214 is disposed on the first busbar 21, and the first insulating layer 214 deviates from the first connecting surface 213. Figure 5As shown, a second insulating layer 224 is provided on the second busbar 22, and the second insulating layer 224 deviates from the second connection surface 223. According to this structure, the first insulating layer 214 can be used to prevent the first busbar 21 from leaking electricity, and the second insulating layer 224 is also the same. In addition, the first connection surface 213 is not covered by the first insulating layer 214, and the second connection surface 223 is not covered by the second insulating layer 224. In this way, after the connector 23 is inserted into the connection slot 24, the first connection surface 213 is also electrically contacted with the second connection surface 223, which helps to improve the conductive performance of the busbar assembly 2.

[0069] Optionally, Figure 4 As shown, the connector 23 includes a neck 231 extending from the first connecting surface 213 and a head 232 at the end of the neck 231. The cross-sectional dimension of the head 232 is greater than the cross-sectional dimension of the neck 231. Figure 5 As shown, the connection groove 24 includes a groove body 241 having an inner cavity 243 and two elastic clamping members 242 extending from the side wall of the groove body 241 into the inner cavity 243. The groove body 241 is arranged in the second connecting portion 222. These elastic clamping members 242 are in the same cross section of the inner cavity 243, and there are gaps between these elastic clamping members 242. In this way, when the connector 23 is plugged into the connection groove 24, the head 232 passes through the gap between the elastic clamping members 242 and enters the inner cavity 243, and the neck 213 is clamped by the elastic clamping members 242. According to this structure, the elastic clamping member 242 clamps the neck 213 and blocks the head 232 from withdrawing from the inner cavity 243, thereby realizing the fixed connection between the connector 23 and the connection groove 24, which does not require an additional auxiliary fixing mechanism, is convenient and quick to operate, and is easy to disassemble and assemble. In addition, during the assembly process, the operator can clearly feel that the elastic clamping member 242 clamps the neck 231 of the connector 23, thereby easily judging whether the first busbar 21 and the second busbar 22 are well connected. It should be understood that in the present application, "these elastic clamping members 242 can be in the same cross section of the inner cavity 243" cannot be understood as a plurality of elastic clamping members 242 being coplanar in a mathematical sense, but one or some elastic clamping members 242 can be slightly deviated from the cross section of the inner cavity 243.

[0070] In one embodiment, Figure 5As shown, the elastic clamping member 242 is constructed as an elastic rod. The two elastic rods are substantially parallel and extend through the inner cavity 243. Overall, this connection groove 24 and the connector 23 together form a form similar to a snap fastener. The gap between the two elastic rods can be determined based on the cross-sectional dimensions of the neck 231 of the connector 23 and the cross-sectional dimensions of the head 232, which will not be repeated here. It should be understood that in other embodiments, the number of elastic rods can also be greater than two, for example, three. In this case, these elastic rods are set to be non-parallel, for example, they can be surrounded to form a gap for the head 232 to pass through; it should be noted that these elastic rods are still used to clamp the neck 231.

[0071] Figure 6 Another form of the connecting groove 24 is schematically shown. In the connecting groove 24, the elastic clamping member 242 is configured as an elastic protrusion, which extends from the side wall of the groove body 241 to the inner cavity 243. The connecting groove 24 of this structure can be an integral structure, which is simpler and can be easily installed on the second busbar 22. In addition, the number of the elastic protrusions can be multiple (for example, four), and these elastic protrusions are spaced apart and distributed along the circumferential direction to clamp the neck 231 of the connector 23 more stably.

[0072] Optionally, Figure 4 As shown, the number of connectors 23 is two. Figure 5 As shown, the number of the connecting slots 24 is also two. According to this structure, after the two connectors 23 are plugged into the corresponding connecting slots 24, the first bus 21 and the second bus 22 will no longer move relative to each other, which helps to maintain the shape of the bus assembly 2. Compared with the case where the number of connectors 23 is greater than two (the number of connecting slots 24 is the same as the number of connectors 23), the solution of the present application has lower requirements on the setting accuracy of the connectors 23 and the connecting slots 24, and the difficulty of plugging the connectors 23 into the connecting slots 24 is also lower. Of course, in the case where the first bus 21 and the second bus 22 need to be able to rotate relative to each other, only one connector 23 and a corresponding one connecting slot 24 may be provided.

[0073] In one embodiment, Figure 4 and Figure 5 As shown, the first connection surface 213 and the second connection surface 223 are both substantially rectangular. In this case, the two connection heads 23 are substantially arranged along the direction of the width W1 of the first connection surface 213; accordingly, the two connection grooves 24 are also substantially arranged along the direction of the width W2 of the second connection surface 223. Of course, the two connection heads 23 can also be substantially arranged along the length direction of the first connection surface 213, and the same is true for the two connection grooves 24.

[0074] Alternatively, if Figure 4As shown, a first sheath 215 is installed on the first busbar 21, and the first sheath 215 includes a first sheath body 216. The first sheath body 216 is installed on the first connecting portion 211 and deviates from the first connecting surface 213. Figure 5 As shown, a second sheath 225 is installed on the second busbar 22, and the second sheath 225 includes a second sheath body 226. The second sheath body 226 is installed on the second connecting portion 222 and deviates from the second connecting surface 223. After the connector 23 is inserted into the connecting groove 24, the first sheath body 216 is connected to the second sheath body 226. In this way, the first sheath body 216 and the second sheath body 226 surround the first connecting portion 211 and the second connecting portion 222 (as shown in FIG. Figure 2 According to this structure, after the first busbar 21 and the second busbar 22 are connected together, the first sheath body 216 and the second sheath body 226 connected together help prevent dust and other pollutants in the external environment from gathering between the first connection surface 213 and the second connection surface 223, and between the connector 23 and the connection groove 24, thereby helping to reduce the resistance of the busbar assembly 2 and improve the connection stability of the first busbar 21 and the second busbar 22.

[0075] In one embodiment, the first sheath 215 and the second sheath 225 are both plastic sheaths to prevent the busbar assembly 2 from leaking electricity.

[0076] Alternatively, if Figure 4 and Figure 7 As shown, four through holes 217 are formed on the first sheath body 216. Figure 5 and Figure 8 As shown, four cams 227 are correspondingly configured on the second sheath body 226. In this way, after the connector 23 is inserted into the connection groove 24, the cams 227 can be adapted to be snapped into the corresponding through holes 217 to connect the first sheath body 216 with the second sheath body 226. During the assembly process, the operator can easily align the cams 227 with the corresponding through holes 217, thereby conveniently connecting the first sheath body 216 with the second sheath body 226. Moreover, the cams 227 and through holes 217 snapped together are also easy to separate, which facilitates the disassembly of the first busbar 21 from the second busbar 22 as needed. It should be understood that the cams 227 can also be set on the first sheath body 216; correspondingly, the through holes 217 are set on the second sheath body 226.

[0077] In one embodiment, a guiding slope (not shown in the figure) is configured on the latching protrusion 227 to further facilitate the operator to latch the latching protrusion 227 into the corresponding through hole 217 .

[0078] In one embodiment, Figure 4As shown, the first busbar 21 is generally in the shape of a cuboid, including a top surface 201, a bottom surface 202, two side surfaces 203 and two end surfaces 204 (only one end surface is shown in the figure). The first connecting portion 211 is located at the end of the first busbar 21, and the first connecting surface 213 is a part of the bottom surface 202. Figure 7 As shown, the first sheath body 216 includes a top wall 2161, an end wall 2164 and two opposite side walls 2163. The end wall 2164 and the two side walls 2163 are connected to the top wall 2161, and the end wall 2164 is also connected between the two side walls 2163. Two through holes 217 are respectively provided on the two side walls 2163. The top wall 2161 of the first sheath 215 is in contact with the top surface 201 of the first busbar 21, the end wall 2164 is in contact with the corresponding end surface 204, and the two side walls 2163 are respectively in contact with the corresponding two side surfaces 203. In the assembled state, the bottom surface 202 of the first busbar 21 faces the second busbar 22, so that the first connecting surface 213 is in contact with the second connecting surface 223.

[0079] like Figure 5 and Figure 8 As shown, the second busbar 22 is similar to the first busbar 21 , and the second sheath body 226 is similar to the first sheath body 216 , which will not be described in detail here. It should be noted that the two side walls of the second sheath body 226 are provided with protrusions 227 that match the through holes 217 .

[0080] Optionally, Figure 4 and Figure 7 As shown, the first sheath 215 also includes a first fixing portion 218. The first fixing portion 218 is connected to the first sheath body 216, and extends in accordance with the first busbar 21 and away from the first connecting portion 211. In this way, the first fixing portion 218 and the first busbar 21 can be wrapped and fixed together using an adhesive tape, thereby fixing the first sheath 215 to the first busbar 21. In addition, according to actual needs, an adhesive can also be applied between the first busbar 21 and the first sheath body 216 and / or the first fixing portion 218 to fix the first sheath 215 to the first busbar 21.

[0081] Similar to the first sheath 215, the second sheath 225 includes a second fixing portion 228 (eg, Figure 5 and Figure 8 The second fixing portion 228 is connected to the second sheath body 226 and extends along the second busbar 22 and away from the second connecting portion 222. In this way, the second fixing portion 228 and the second busbar 22 can be fixed together by using an adhesive tape, or an adhesive can be applied to the second busbar 22 and the second sheath body 226 and / or the second fixing portion 228, so as to fix the second sheath 225 to the second busbar 22.

[0082] Figure 3 A variation of the busbar assembly 2 is schematically shown. Figure 3 As shown, in the busbar assembly 2, the first connecting portion 211 is folded relative to the rest of the first busbar 21, and the second busbar 22 is not folded. The second busbar 22 is arranged to be substantially at a right angle to the first busbar 21. This realizes the turning of the busbar assembly 2 to adapt to the installation environment in the vehicle. It should be understood that the first busbar 21 and / or the second busbar 22 can also be bent into other forms according to actual conditions, which will not be repeated here.

[0083] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
