These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0044] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art may adjust them as needed to suit specific applications.

[0045] Secondly, it should be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0046] Then, it should be noted that, in the description of this application, the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, unless otherwise specified, "plurality" means two or more.

[0048] As shown in the background technology, in the prior art, a battery pack generally includes a tray, a battery disconnect unit, a high-voltage copper busbar and a high-voltage plug-in. The high-voltage copper busbar is first connected to the battery disconnect unit, and the battery disconnect unit and the high-voltage plug-in are both installed on the tray. Then, the high-voltage plug-in is connected to the high-voltage copper busbar by bolts.

[0049] However, the above connection method is not convenient for installation and adjustment, and since manufacturing tolerances or assembly errors are difficult to avoid, assembly gaps or interference may occur when the high-voltage plug-in is connected to the high-voltage copper busbar, resulting in poor assembly effect of the high-voltage plug-in and the high-voltage copper busbar.

[0050] Based on this, the connection structure, battery pack and electrical equipment provided by the present application, the connection structure is connected to the tray by setting a tray, a connector, a battery disconnect unit, a copper busbar and a connection assembly, the connector being connected to the tray. The battery disconnect unit is installed in the tray, and a mounting part is provided on the battery disconnect unit. The connection assembly connects the copper busbar to the mounting part; at least part of the connection assembly can be moved relative to the mounting part, and drives the copper busbar to move, thereby adjusting the position of the copper busbar to facilitate the connection between the copper busbar and the connector. The connection structure, battery pack and electrical equipment provided by the present application are easy to install and adjust, and improve the assembly effect of the connector and the copper busbar.

[0051] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. 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 this application.

[0052] Reference Figure 1 and Figure 2 As shown, in the first aspect, the connection structure provided by the present application includes: a tray 100, a connector 200, a battery disconnect unit 300, a copper busbar 400 and a connection assembly 500, wherein the connector 200 is connected to the tray 100.

[0053] The battery disconnect unit 300 is installed in the tray 100 , and a mounting member 310 is provided on the battery disconnect unit 300 .

[0054] The connecting component 500 connects the copper busbar 400 to the mounting component 310 . The connecting component 500 is configured so that at least a portion of the connecting component 500 can move relative to the mounting component 310 and drive the copper busbar 400 to move so that the copper busbar 400 is connected to the connector 200 .

[0055] As can be understood, the tray 100 provides a stable mounting base for the battery disconnect unit 300, the connector 200, and other components. By fixing these components on the tray 100, they can remain stable during the operation of the vehicle or equipment, reducing the impact of vibration and shock on the system.

[0056] Connector 200 is an electrical connector used to connect a battery pack to a vehicle or equipment high-voltage system. It can be used in electric vehicles, power tools, and other applications that require a high-voltage battery system. Connector 200 can ensure the safe transmission of high-voltage current, reduce the possibility of arcing and short circuits, and protect the safety of equipment and personnel.

[0057] The connector 200 is connected to the tray 100. For example, a flange may be provided on the connector 200, and threaded holes may be provided on the outer wall of the tray 100. The connector 200 is connected to the outer wall of the tray 100 by bolts through the flange and the threaded holes.

[0058] It should be noted that the primary function of the Battery Disconnect Unit (BDU) 300 is to manage and control the connection and disconnection between the battery pack and the vehicle's electrical system. The BDU 300 typically includes contactors, fuses, and other safety components to ensure safe disconnection of the battery pack when necessary, preventing overcurrent, short circuits, or other electrical faults, thereby protecting the battery and the vehicle's electrical system.

[0059] The battery disconnect unit 300 is installed in the tray 100. For example, a lifting lug may be provided in the tray 100. Through holes are provided on both sides of the battery disconnect unit 300, and bolts are passed through the through holes to connect with the lifting lug.

[0060] Specifically, since the connecting component 500 connects the copper busbar 400 to the mounting component 310, and at least part of the connecting component 500 can move relative to the mounting component 310, the connecting component 500 can drive the copper busbar 400 to move, thereby adjusting the position of the copper busbar 400, and compensating for the misalignment caused by manufacturing tolerances or assembly errors, so that the copper busbar 400 and the connector 200 can be accurately aligned, facilitating the connection between the copper busbar 400 and the connector 200, thereby improving the assembly effect of the connector 200 and the copper busbar 400.

[0061] It should also be noted that during the assembly process, fixed connections may cause stress between components due to tolerance accumulation. The movable connection component 500 can relieve these stresses and reduce potential damage to the components, thereby extending the service life of the system.

[0062] Since the connecting assembly 500 is movable, workers do not need to make too many adjustments or reprocessing during the installation process, thereby improving assembly efficiency and saving time and costs.

[0063] By ensuring the correct connection between the copper busbar 400 and the plug connector 200 , the risk of poor contact is reduced, thereby improving the reliability and performance of the electrical connection.

[0064] The present application provides a connection structure, a battery pack, and an electrical device. The connection structure is provided by setting a tray 100, a connector 200, a battery disconnect unit 300, a copper busbar 400, and a connection assembly 500. The connector 200 is connected to the tray 100. The battery disconnect unit 300 is installed in the tray 100, and a mounting member 310 is provided on the battery disconnect unit 300. The connection assembly 500 connects the copper busbar 400 to the mounting member 310; at least part of the connection assembly 500 can move relative to the mounting member 310 and drive the copper busbar 400 to move, thereby adjusting the position of the copper busbar 400 to facilitate the connection between the copper busbar 400 and the connector 200. The connection structure, battery pack, and electrical device provided by the present application are easy to install and adjust, and improve the assembly effect of the connector 200 and the copper busbar 400.

[0065] In some embodiments, reference Figures 2 to 5 As shown, the connection assembly 500 includes a first connection member 510 and a second connection member 520 connected to the first connection member 510 . The first connection member 510 is used to connect the copper busbar 400 .

[0066] The mounting member 310 defines a mounting hole 311 therein, and the second connecting member 520 is inserted into the mounting hole 311 .

[0067] Specifically, the first connector 510 provides a stable connection point for the copper busbar 400 , simplifies the installation process of the copper busbar 400 , and ensures the reliability of the electrical connection.

[0068] It should be noted that although the copper busbar 400 is fixed on the first connector 510, the first connector 510 is connected to the second connector 520, and the second connector 520 is inserted into the mounting hole 311 of the mounting member 310. The second connector 520 can be moved and adjusted to a certain extent relative to the mounting hole 311, so that the first connector 510 and the copper busbar 400 can move and adjust synchronously with the second connector 520, which helps to compensate for the misalignment caused by manufacturing tolerances or assembly errors during the assembly process, so that the copper busbar 400 can be accurately aligned and connected to the connector 200.

[0069] In some embodiments, reference Figure 5 As shown, the second connecting member 520 has a first limiting portion 521 , and the second connecting member 520 abuts against the hole wall of the mounting hole 311 through the first limiting portion 521 .

[0070] It should be noted that by providing a first limiting portion 521 on the second connecting member 520, the first limiting portion 521 abuts against the hole wall of the mounting hole 311, so that the second connecting member 520 remains stable in the mounting hole 311, thereby improving the stability and reliability of the connection between the second connecting member 520 and the mounting member 310.

[0071] In some embodiments, reference Figure 5 As shown, a second limiting portion 3111 is defined in the mounting hole 311 . The second limiting portion 3111 is configured to abut against the first limiting portion 521 to limit the first limiting portion 521 within the mounting hole 311 .

[0072] Specifically, by providing the second limiting portion 3111, the second limiting portion 3111 limits the first limiting portion 521 within the mounting hole 311, thereby preventing the second connecting member 520 from detaching from the mounting hole 311, thereby improving the reliability of the connection between the second connecting member 520 and the mounting member 310.

[0073] The second limiting portion 3111 abuts against the first limiting portion 521 , providing a dual limiting function, thereby ensuring accurate positioning of the second connecting member 520 within the mounting hole 311 and preventing the second connecting member 520 from being excessively moved or over-inserted.

[0074] In some embodiments, reference Figure 5 As shown, a first abutting portion 511 and a second abutting portion 512 are respectively provided at both ends of the first connecting member 510 . The first abutting portion 511 and the second abutting portion 512 respectively abut against opposite sides of the copper busbar 400 to restrict the copper busbar 400 on the first connecting member 510 .

[0075] It can be understood that by providing the first abutting portion 511 and the second abutting portion 512 , the copper busbar 400 is ensured to be firmly fixed on the first connecting member 510 , thereby preventing the copper busbar 400 from loosening or shifting during use and improving the stability of the connection.

[0076] By ensuring the stability and correct positioning of the copper busbar 400 , the reliability of the electrical connection is improved, the possibility of electrical failure due to poor connection is reduced, and the safety of the system is improved.

[0077] In some embodiments, reference Figure 6 As shown, the connecting assembly 500 includes a third connecting member 530 and an elastic member 540. The elastic member 540 and the copper busbar 400 are sequentially mounted on the mounting member 310. The mounting member 310 is connected to the third connecting member 530. The opposite sides of the copper busbar 400 are respectively in contact with the elastic member 540 and the third connecting member 530.

[0078] Specifically, the elastic member 540 has a certain flexibility and compressibility and can be deformed within a certain range, allowing the copper busbar 400 to be fine-tuned and repositioned during the installation process, thereby alleviating the misalignment caused by manufacturing tolerances or assembly errors, so that the copper busbar 400 and the connector 200 can be accurately aligned, thereby improving the assembly effect of the connector 200 and the copper busbar 400.

[0079] By providing buffering and shock absorption functions, the elastic member 540 can reduce the mechanical stress caused by misalignment, thereby not only protecting the connection assembly 500 but also ensuring that the copper busbar 400 can remain stable in the correct position.

[0080] It should be noted that the third connecting member 530 provides a stable support point, and works together with the elastic member 540 to ensure that the copper busbar 400 can remain in the correct position after adjustment, thereby preventing misalignment during use.

[0081] Assemblers can utilize the deformation characteristics of the elastic member 540 to achieve a better alignment effect without the need for additional processing or adjustment of the components, thereby improving the assembly accuracy and reliability of the system.

[0082] In some embodiments, reference Figure 6 As shown, one of the third connecting member 530 and the mounting member 310 is provided with an internal thread, and the other is provided with an external thread matching the internal thread.

[0083] It can be understood that the threaded connection provides a strong mechanical connection method, can withstand greater mechanical stress and vibration, can ensure a tight connection between the third connecting member 530 and the mounting member 310, and improve the reliability of the connection.

[0084] The third connecting member 530 and the mounting member 310 can be connected or separated by simply rotating without the need for additional tools or complicated operations, making the assembly and disassembly process simple and efficient, thereby improving assembly efficiency.

[0085] In a specific implementation, an internal thread can be set on the third connecting member 530, and an external thread matching the internal thread can be set on the mounting member 310; or an internal thread can be set on the mounting member 310, and an external thread matching the internal thread can be set on the third connecting member 530. The embodiment of the present application does not impose too many restrictions on this.

[0086] In some embodiments, reference Figure 7 As shown, one of the third connecting member 530 and the mounting member 310 is provided with an inserting hole 312 , and the other has an inserting portion 531 that can be inserted into the inserting hole 312 .

[0087] It can be understood that the plug-in design allows for quick and easy connection and disassembly without the need for complicated tools or operations. The assembly or disassembly process can be completed with a simple insertion or removal action, thereby improving assembly and disassembly efficiency.

[0088] In a specific implementation, a plug-in hole 312 can be set on the third connecting member 530, and a plug-in portion 531 that can be plugged into the plug-in hole 312 can be set on the mounting member 310; or a plug-in hole 312 can be set on the mounting member 310, and a plug-in portion 531 that can be plugged into the plug-in hole 312 can be set on the third connecting member 530. The embodiments of the present application do not impose too many restrictions on this.

[0089] In some embodiments, reference Figure 7 As shown, a protrusion 5311 is provided on the plug-in portion 531 , and a limiting groove 3121 is provided in the plug-in hole 312 . The protrusion 5311 is engaged in the limiting groove 3121 to limit the plug-in portion 531 in the plug-in hole 312 .

[0090] Specifically, the protrusion 5311 is snapped into the limiting groove 3121, providing additional mechanical locking to prevent it from loosening or falling off due to vibration or external force during use, thereby improving the stability and safety of the plug-in portion 531 in the plug-in hole 312.

[0091] The limiting groove 3121 not only provides a locking function, but also helps to accurately position the plug-in portion 531 so that the plug-in portion 531 can be aligned and maintain the correct position during the assembly process, thereby improving the reliability of the assembly.

[0092] In some embodiments, reference Figure 6 and Figure 7 As shown, the mounting member 310 is provided with a third abutting portion 313 , and two ends of the elastic member 540 abut against the copper busbar 400 and the third abutting portion 313 respectively.

[0093] It should be noted that the third abutting portion 313 provides a support point for the elastic member 540 , so that the elastic member 540 can stably abut against the copper busbar 400 , thereby helping to improve the stability and reliability of the copper busbar 400 during use.

[0094] In some embodiments, reference Figure 8 As shown, the plug connector 200 has a first connecting portion 210 , and the copper busbar 400 is provided with a second connecting portion 410 , and the first connecting portion 210 is connected to the second connecting portion 410 .

[0095] Specifically, by providing the first connecting portion 210 and the second connecting portion 410, not only a stable mechanical connection is provided between the plug connector 200 and the copper busbar 400, but also a reliable electrical connection is achieved. For example, the first connecting portion 210 and the second connecting portion 410 can be connected by bolts or other methods, and this embodiment of the present application does not impose any restrictions on this.

[0096] In some embodiments, reference Figure 8As shown, at least one of the connector 200 and the copper busbar 400 is provided with a guide slope 211 .

[0097] It can be understood that the guide bevel 211 helps to achieve automatic alignment during the assembly process. When the connector 200 and the copper busbar 400 approach each other, the guide bevel 211 can guide them into the correct position and angle, thereby simplifying the alignment process and improving assembly efficiency.

[0098] In a second aspect, the present application provides a battery pack, comprising a battery pack body and a connection structure provided in the first aspect above and arranged on the battery pack body.
