[0056] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0058] The terms “first,” “second,” “third,” and “fourth,” etc. (if present), in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0059] As described in the background section, the battery pack includes a frame, within which multiple cell groups, a busbar, a BDU module, and a charging / discharging socket are arranged. The multiple cell groups are connected in series and parallel via the busbar, and the two ends of the busbar are connected to the charging / discharging socket and the BDU module, respectively. The charging / discharging socket is used to connect to the electric drive components of the electric vehicle.

[0060] Among them, reference Figure 8 As shown, the BDU module and the charging / discharging socket are usually located on opposite sides of the frame. The battery pack is located between the BDU module and the charging / discharging socket. When the busbar is connected to the BDU module, the end of the busbar closest to the BDU module needs to be bent in order to connect to the mounting position on the BDU module.

[0061] However, the busbar's bending radius is insufficient, making it impossible to directly flip its direction to connect with the BDU module. It can only be bent manually, resulting in a large space occupation when installed within the frame.

[0062] To address the aforementioned problems in the prior art, this utility model provides a busbar lead-out assembly, a battery pack, and a vehicle. The busbar lead-out assembly includes a lead-out member and an adapter member. The lead-out member is connected to the adapter member, and the lead-out member is located to the side of the adapter member. The lead-out member is used to connect to the busbar, and the adapter member is used to connect to the BDU module, so as to electrically connect the busbar and the BDU module through the lead-out member and the adapter member. In the battery pack, the busbar and the BDU module can be connected through the lead-out member and the adapter member, thus eliminating the need to bend the busbar and facilitating installation. Furthermore, it occupies little space, allowing for a more compact overall structure.

[0063] The following describes exemplary application scenarios of this utility model.

[0064] The busbar leading-out assembly provided by the utility model can be applied to a battery pack of a new energy automobile, such as a battery pack of a pure electric drive vehicle, a battery pack of a plug-in hybrid vehicle and the like. Specifically, the busbar leading-out assembly provided by the utility model can be connected by a leading-out piece and an adapter piece in the battery pack, so that the busbar does not need to be bent, and the installation is convenient. Moreover, the busbar leading-out assembly occupies a small space, and can make the overall structure more compact.

[0065] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.

[0066] Referring to Figures 1 to 7 The present application provides a busbar leading-out assembly 100, which comprises a leading-out piece 110 and an adapter piece 120.

[0067] The leading-out piece 110 is connected with the adapter piece 120, and the leading-out piece 110 is located at the side of the adapter piece 120.

[0068] The leading-out piece 110 is used to be connected with the busbar 400, and the adapter piece 120 is used to be connected with the BDU module 500, so as to electrically connect the busbar 400 and the BDU module 500 through the leading-out piece 110 and the adapter piece 120.

[0069] It can be understood that the busbar leading-out assembly 100 provided by the present application can be used in a battery pack, and the battery pack comprises a busbar 400 and a BDU module 500. The busbar 400 is used to connect each battery cell group 300 in series and in parallel, and the BDU module 500 is used to control the charging and discharging process of the battery cell group 300. The busbar 400 and the BDU module 500 are connected in conduction through the busbar leading-out assembly 100, so that the busbar 400 does not need to be bent additionally.

[0070] Referring to Figure 1 and Figure 6 The leading-out piece 110 is located at the side of the adapter piece 120, one end of the leading-out piece 110 away from the adapter piece 120 is connected with the busbar 400, and one end of the adapter piece 120 away from the leading-out piece 110 is connected with the BDU module 500, so that the busbar 400 does not need to be bent, and the installation is convenient.

[0071] At the same time, referring to Figure 8As shown, in the battery pack, the internal space of the frame 200 can be divided into the cell cavity and the electrical cavity by the cross beam, the cell group 300 is installed in the cell cavity, the BDU module 500 is installed in the electrical cavity, and the busbar 400 is arranged perpendicularly to the cross beam and across the cell cavity and the electrical cavity. Since the busbar 400 is perpendicular to the BDU module 500, when the bending radius of the busbar 400 is not enough, the space of the electrical cavity needs to be expanded to meet the installation requirement, which will cause the volume of the battery pack to be relatively large.

[0072] The busbar leading assembly 100 provided by the application is used in the battery pack, the busbar 400 is connected with the leading piece 110, the adapter 120 on the side of the leading piece 110 is connected with the BDU module 500, so that the busbar 400 and the BDU module 500 are connected by bending and turning, the occupied space is small, and the overall structure of the battery pack is more compact.

[0073] For example, referring to Figure 6 As shown, the mounting positions of the busbar 400 and the BDU module 500 can be arranged in the +X direction, after the leading piece 110 is connected with the busbar 400, the extension direction of the adapter 120 is arranged in the +X direction and connected with the mounting positions on the BDU module 500 correspondingly. Of course, the mounting positions of the busbar 400 and the BDU module 500 can also be arranged in the -X direction, in this case, on the basis of the above-mentioned scheme, the adapter 120 only needs to be turned over and connected with the mounting positions on the BDU module 500 correspondingly. In this way, the busbar leading assembly 100 provided by the application can conveniently connect the mounting positions of the busbar 400 and the BDU module 500 and can be converted in the +X direction and the -X direction.

[0074] For example, the materials of the leading piece 110 and the adapter 120 can be copper, nickel, silver, gold-plated materials and other alloy materials, as long as the busbar 400 and the BDU module 500 can be connected in conduction, and the embodiments of the application do not make too many limitations on this.

[0075] In one embodiment, referring to Figure 3 and Figure 6 As shown, the leading piece 110 has a leading surface 111, and the adapter 120 has an adapter surface 121.

[0076] The leading surface 111 abuts against the busbar 400, and the adapter surface 121 abuts against the BDU module 500.

[0077] The leading surface 111 is perpendicular to the adapter surface 121.

[0078] In the above embodiment, the lead-out surface 111 of the lead-out piece 110 is perpendicular to the adapter surface 121 of the adapter piece 120, and when installed, the busbar 400 and the BDU module 500 can be connected in a vertical twist manner, thereby facilitating installation.

[0079] For example, as shown in Figure 3 and Figure 6 , when installed, the lead-out surface 111 can be in a vertical state, and the adapter surface 121 can be in a horizontal state. The lead-out piece 110 is abutted to one side of the busbar 400 through the lead-out surface 111, and the adapter piece 120 is abutted to the installation position on the top of the BDU module 500 through the adapter surface 121. In this way, the vertical lead-out direction is twisted into a horizontal lead-out direction, thereby facilitating installation.

[0080] It can be understood that, as shown in Figure 6 and Figure 7 , the busbar 400 can have a sheet structure, and the busbar 400 can be installed vertically. The vertical installation of the busbar 400 means that the wider side of the busbar 400 is installed in a vertical state, and the narrower side is installed in a horizontal state.

[0081] As shown in Figure 6 and Figure 7 , the lead-out surface 111 of the lead-out piece 110 is abutted to the wider side of the busbar 400 in the vertical direction, thereby increasing the contact area between the lead-out piece 110 and the busbar 400, improving the conduction efficiency, and facilitating the installation between the lead-out piece 110 and the busbar 400.

[0082] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the busbar lead-out assembly 100 provided by the present application further comprises a connecting piece 130.

[0083] The lead-out piece 110 and the adapter piece 120 are detachably connected through the connecting piece 130.

[0084] In the above embodiment, the connecting piece 130 is mainly used for detachable connection of the lead-out piece 110 and the adapter piece 120. When any one of the lead-out piece 110 and the adapter piece 120 is damaged, it can be replaced in time, thereby reducing the cost. Meanwhile, according to the positional relationship between the busbar 400 and the installation position on the BDU module 500, the lead-out piece 110 and the adapter piece 120 with appropriate sizes can be selected for assembly, thereby improving the flexibility of installation.

[0085] Exemplarily, the lead-out piece 110 and the adapter piece 120 can be provided with through holes, the connecting piece 130 is provided with threaded holes, and the lead-out piece 110 and the adapter piece 120 are fixed on the connecting piece 130 by bolts respectively. The lead-out piece 110 and the adapter piece 120 can also be provided with buckle parts respectively, and the connecting piece 130 is provided with a clamping groove, and the lead-out piece 110 and the adapter piece 120 are locked and connected with the clamping groove on the connecting piece 130 by the buckle parts. Of course, the detachable connection structure between the lead-out piece 110, the adapter piece 120 and the connecting piece 130 can also be other structures, and the application does not make too many limitations on this.

[0086] Exemplarily, the material of the connecting piece 130 can be copper, nickel, silver, gold-plated material and other alloy materials, and the embodiments of the application do not make too many limitations on this.

[0087] In an embodiment, as shown in Figure 2 , Figure 4 and Figure 5 , the lead-out piece 110 is provided with a first mounting clamping groove 112, and the adapter piece 120 is provided with a second mounting clamping groove 122.

[0088] The first mounting clamping groove 112, the second mounting clamping groove 122 and the connecting piece 130 are matched by mortise and tenon structure to connect the lead-out piece 110 and the adapter piece 120.

[0089] In the above embodiment, the lead-out piece 110, the adapter piece 120 and the connecting piece 130 are connected by the mortise and tenon structure, without the need to additionally introduce fastening structures such as bolts, and the installation is very convenient. At the same time, this connection method has good stability, and the lead-out piece 110 and the adapter piece 120 will not move relatively, causing damage to the busbar 400 and the BDU module 500.

[0090] Specifically, as shown in Figure 2 , Figure 4 and Figure 5 , the first mounting clamping groove 112 includes a first guide segment 1121 and a first limiting segment 1122 in communication with the first guide segment 1121, the second mounting clamping groove 122 includes a second guide segment 1221 and a second limiting segment 1222 in communication with the second guide segment 1221, and the connecting piece 130 is provided with a mounting through hole 131.

[0091] The connecting piece 130 is configured to be inserted on the lead-out piece 110 through the mounting through hole 131.

[0092] The adapter piece 120 is configured to be inserted on the lead-out piece 110 and the connecting piece 130 at the second guide segment 1221 through the first guide segment 1121, and the mounting through hole 131, the first guide segment 1121 and the second limiting segment 1222 are in communication.

[0093] In the above embodiment,Figure 2 As shown, one end of the first guiding segment 1121 is open, and the other end of the first guiding segment 1121 is in communication with the first limiting segment 1122. One end of the second guiding segment 1221 is open, and the other end of the second guiding segment 1221 is in communication with the second limiting segment 1222.

[0094] In the installation, referring to Figure 4 As shown, the connecting piece 130 can be inserted into the leading-out piece 110 through the installation through hole 131, and then the connecting piece 130 is aligned with the second limiting segment 1222 of the adapter piece 120, part of the leading-out piece 110 is aligned with the second guiding segment 1221 of the adapter piece 120, and the opening of the first guiding segment 1121 on the leading-out piece 110 is aligned with the part of the adapter piece 120 for forming the second limiting segment 1222.

[0095] Then, referring to Figure 1 and Figure 5 As shown, the adapter piece 120 is moved towards the leading-out piece 110 and the connecting piece 130, so that the adapter piece 120 is inserted into the leading-out piece 110 and the connecting piece 130, and the installation through hole 131, the first guiding segment 1121 and the second limiting segment 1222 are in communication, and the mortise and tenon connection between the leading-out piece 110, the adapter piece 120 and the connecting piece 130 is completed.

[0096] Through the above structure, the installation and cooperation between the leading-out piece 110, the adapter piece 120 and the connecting piece 130 can be facilitated, so as to improve the installation efficiency.

[0097] For example, referring to Figure 1 , Figure 2 and Figure 3 As shown, the leading-out piece 110, the adapter piece 120 and the connecting piece 130 can all be rectangular bodies, the shape of the installation through hole 131 can be rectangular, the first installation clamping groove 112 can be a 7-shaped structure, and the second installation clamping groove 122 can be a T-shaped structure. The size of the installation through hole 131 is adapted to the leading-out piece 110, the size of the second limiting segment 1222 is adapted to the connecting piece 130, the size of the second guiding segment 1221 is adapted to the leading-out piece 110, and the size of the first guiding segment 1121 and the size of the first limiting segment 1122 are both adapted to the adapter piece 120.

[0098] In an embodiment, referring to Figure 1 and Figure 3 As shown, the leading-out piece 110, the adapter piece 120 and the connecting piece 130 are perpendicular to each other.

[0099] In the above embodiment, the leading-out piece 110, the adapter piece 120 and the connecting piece 130 are perpendicular to each other, which can avoid occupying too much working space, and the stability of the connection between the three is stronger.

[0100] Specifically, referring to Figure 6 and Figure 7 shown, the lead-out piece 110 is connected with one side of the busbar 400 through the lead-out surface 111, the adapter piece 120 is connected with the mounting position of the BDU module 500 through the adapter surface 121, and the connecting piece 130 can abut against the shell of the BDU module 500 to support the lead-out piece 110 and the adapter piece 120, avoiding the connection of the lead-out piece 110 and the adapter piece 120 from sinking under gravity and causing damage. Thus, the lead-out piece 110, the adapter piece 120 and the connecting piece 130 are perpendicular to each other, which can avoid occupying too much working space, make the overall structure more compact, and also make the installation more stable.

[0101] In an embodiment, referring to Figure 1 , Figure 2 and Figure 6 shown, the lead-out piece 110 is provided with at least one first mounting hole 113, and the adapter piece 120 is provided with at least one second mounting hole 123.

[0102] The busbar lead-out assembly 100 provided by the application further comprises a first fastener and a second fastener, and the first fastener is used to connect the lead-out piece 110 and the busbar 400 through the first mounting hole 113.

[0103] The second fastener connects the adapter piece 120 and the BDU module 500 through the second mounting hole 123.

[0104] In the above embodiment, the first fastener can pass through the first mounting hole 113 on the lead-out piece 110 to connect the lead-out piece 110 and the busbar 400 together. For example, the first fastener can be an insulating cable tie, which passes through the first mounting hole 113 to tightly connect the lead-out piece 110 and the busbar 400. Of course, the first fastener can also be other similar structures as long as it can connect the lead-out piece 110 and the busbar 400, and the application does not make too many limitations on this.

[0105] Referring to Figure 6 and Figure 7 shown, the second fastener can pass through the second mounting hole 123 on the adapter piece 120 to connect the adapter piece 120 and the mounting position on the BDU module 500 together. For example, the second fastener can be a pull rivet nut, one end of which passes through the second mounting hole 123 to connect the adapter piece 120 and the mounting position on the BDU module 500. Of course, the second fastener can also be other similar structures as long as it can connect the adapter piece 120 and the mounting position on the BDU module 500, and the application does not make too many limitations on this.

[0106] Exemplarily, the at least one first mounting hole 113 and the at least one second mounting hole 123 can each be one or multiple, and the application does not make too many limitations on this.

[0107] In an embodiment, referring to Figure 1 and Figure 2 , at least one end of the lead-out piece 110 is provided with a first chamfer 114, and at least one end of the adapter piece 120 is provided with a second chamfer 124.

[0108] In the above embodiment, the end of the lead-out piece 110 is provided with the first chamfer 114, so that when the lead-out piece 110 is connected with the busbar 400, the end of the lead-out piece 110 will not scratch the surface of the busbar 400, thereby avoiding the busbar 400 from being abraded during installation.

[0109] The end of the adapter piece 120 is provided with the second chamfer 124, so that when the adapter piece 120 is connected with the BDU module 500, the end of the adapter piece 120 will not scratch the BDU module 500, thereby avoiding the BDU module 500 from being abraded during installation.

[0110] Referring to Figure 6 , Figure 7 and Figure 8 , the application provides a battery pack, which comprises a busbar 400, a BDU module 500 and the busbar lead-out assembly 100 as above.

[0111] The busbar 400 is connected with the lead-out piece 110 of the busbar lead-out assembly 100, and the BDU module 500 is connected with the adapter piece 120 of the busbar lead-out assembly 100.
