[0002] The utilization of new energy batteries significantly reduces greenhouse gas and harmful pollutant emissions. Their high-efficiency energy conversion and resource recycling reduce energy waste and dependence on minerals; simultaneously, they promote the development of renewable energy, balance grid load, reduce dependence on fossil fuels, and enhance energy security. As a major component of new energy battery packs, battery modules require busbar bracket assembly welding to the battery modules after cell stacking. This serves two purposes: firstly, it connects individual cells in series for electrical connection and improves energy output efficiency; secondly, it ensures mechanical strength and structural stability, preventing safety hazards such as contact loosening due to vibration or impact. However, existing busbar brackets typically employ a hot-riveting process, which is inconvenient for busbar installation. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A busbar mounting structure includes a structural body for supporting the busbar, and a limiting member and a limiting unit disposed on the structural body;

[0006] The limiting member is inserted into the structure body along the first direction and presses the busbar against the structure body along the second direction. The limiting unit can limit the displacement of the limiting member in the first direction.

[0007] The structure body is provided with a first limiting part and a second limiting part. The first limiting part can limit the displacement of the busbar in the first direction, and the second limiting part and the limiting member can limit the displacement of the busbar in the third direction.

[0008] Furthermore, the first limiting portion includes a limiting protrusion disposed on the structural body; the limiting protrusion protrudes along the second direction and is spaced apart from the limiting member in the third direction.

[0009] Furthermore, the second limiting part includes a limiting block disposed on the structural body; the limiting block can be inserted into the limiting groove of the busbar along the third direction and restrict the displacement of the busbar in the first direction.

[0010] Furthermore, both the limiting protrusion and the limiting member are elongated strips extending along the first direction;

[0011] The limiting blocks are a plurality of blocks spaced apart along the first direction.

[0012] Furthermore, the structure body is provided with a recessed clearance groove along the second direction; the clearance groove is used to avoid the bent portion on the busbar.

[0013] Furthermore, the limiting unit includes a stop block and a limiting slider respectively disposed at both ends of the structural body in the first direction; the limiting slider is inserted into the structural body along the third direction and abuts against both ends of the limiting member with the stop block respectively.

[0014] Furthermore, a fastener is screwed between the limiting slider and the limiting member; the fastener connects the limiting slider and the limiting member together along the first direction.

[0015] Furthermore, the limiting slider is provided with a limiting part, which presses the busbar against the structural body along the second direction.

[0016] Furthermore, the limiting member includes a main body and a protrusion protruding from one side of the main body along the second direction; the structural body is provided with a sliding groove, the protrusion is inserted into the sliding groove, the main body is provided with a limiting notch on the side opposite to the second limiting part, one side wall of the limiting notch abuts against the side of the busbar, and the other side wall of the limiting notch abuts against the end face of the busbar.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] (1) The busbar installation structure of this utility model can realize the limiting of the busbar on the structure body by means of the first limiting part and the second limiting part provided on the structure body, and the cooperation with the limiting member and the limiting unit. The setting of the limiting member inserted on the structure body can simplify the assembly process and facilitate the installation of the busbar.

[0019] (2) The first limiting part includes a limiting protrusion provided on the structural body. The limiting protrusion protrudes along the second direction and is spaced apart from the limiting member in the third direction. This arrangement can limit the busbar in the third direction. At the same time, its structure is simple, easy to manufacture, and also helps to reduce costs.

[0020] (3) The second limiting part includes a limiting block disposed on the structural body. The limiting block can be inserted into the limiting groove of the busbar in a third direction and restricts the displacement of the busbar in the first direction. In this way, by providing a limiting block inserted into the structural body in a third direction, the positioning of the limiting block can be reliably ensured, and the busbar can be easily disassembled, thereby facilitating the disassembly and maintenance of the busbar, which in turn helps to improve the production efficiency of the busbar assembly and reduce production costs.

[0021] (4) Both the limiting protrusion and the limiting element are elongated strips extending along the first direction, and the limiting blocks are multiple blocks spaced apart along the first direction. In this way, the elongated limiting protrusion and the limiting element can generate a larger contact area with the busbar, thus avoiding stress concentration. At the same time, the multiple limiting blocks spaced apart along the first direction can effectively limit the position of each busbar in the first direction, thereby facilitating subsequent welding processes, which in turn helps to reduce production difficulty and production costs.

[0022] (5) The main body of the structure is provided with a recessed relief groove along the second direction, which is used to avoid the bending part on the busbar. This setting can avoid interference between the stamped bending part on the busbar and the busbar support, thereby avoiding the busbar not being able to fit tightly with the busbar support.

[0023] (6) The limiting unit includes a stop block and a limiting slider respectively disposed at both ends of the structural body in the first direction. The limiting slider is inserted into the structural body in the third direction and abuts against both ends of the limiting component with the stop block. This arrangement can achieve limiting in the first direction and ensure the structural strength of the busbar installation structure. At the same time, the limiting slider inserted into the structural body in the third direction can achieve reliable connection and facilitate disassembly, thereby facilitating the disassembly and maintenance of the busbar and improving the production efficiency of the busbar assembly.

[0024] (7) A fastener is screwed between the limiting slider and the limiting component, and the fastener connects the limiting slider and the limiting component together in the first direction. This setting ensures the reliability of the limiting slider connection, thereby preventing the limiting slider from coming off due to vibration or impact, which is conducive to improving safety performance. At the same time, the screw connection method can not only achieve a reliable connection, but also facilitate disassembly, which is conducive to the disassembly and maintenance of the busbar, and thus further improves the production efficiency of the busbar assembly.

[0025] (8) The limiting slider is provided with a limiting part, which presses the busbar against the structure body along the second direction. This setting can improve the positioning reliability of the busbar, ensure that the busbar is firmly fixed in the second direction, and cooperate with other limiting components to form multi-directional limiting of the busbar, preventing the busbar from loosening or shaking in any direction.

[0026] (9) The limiting component includes a main body and a protrusion protruding from one side of the main body along the second direction. The main body is provided with a sliding groove, and the protrusion is inserted into the sliding groove. A limiting notch is provided on the side of the main body opposite to the second limiting part. One side wall of the limiting notch abuts against the side of the busbar, and the other side wall of the limiting notch abuts against the end face of the busbar. This configuration can ensure the reliability of the busbar's positioning in the first and second directions, while also making the busbar easy to disassemble and maintain, and also improving the production efficiency of the busbar assembly.

[0027] This application also proposes a battery pack having a bus mounting structure as described above.

[0028] The battery pack of this application, by setting the busbar mounting structure as described above, can realize the limiting of the busbar on the structure body, thereby simplifying the assembly process, facilitating the installation of the busbar, and realizing the busbar repair, which in turn helps to reduce the difficulty of battery pack production, reduce production costs, and further enhance the market competitiveness of the battery pack.

[0048] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0050] Furthermore, it should be noted that in the description of this application, if terms such as "upper," "lower," "inner," or "outer" appear, indicating orientation or positional relationship, these are based on the orientation or positional 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, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0052] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0054] The first aspect of this application provides a bus installation structure, which is mainly used to facilitate bus installation. Furthermore, the bus installation structure of this embodiment utilizes an innovative structural design to simplify the assembly process while facilitating bus installation.

[0055] In related technologies, battery modules, as a major component of new energy battery packs, require busbar bracket assembly welding to the battery modules after the module cells are stacked. This serves two purposes: firstly, it connects the individual cells in series to achieve electrical connection and improve energy output efficiency; secondly, it ensures mechanical strength and structural stability, preventing safety hazards such as contact loosening due to vibration or impact. However, existing busbar brackets in related technologies typically employ a hot riveting process, which is inconvenient for busbar installation.

[0056] In view of this, in order to overcome the shortcomings of the prior art, the bus installation structure of this embodiment combines... Figures 1 to 13 As shown, the overall design includes a structural body 2 for supporting the busbar 1, and a limiting member 3 and a limiting unit disposed on the structural body 2.

[0057] The limiting member 3 is inserted into the structural body 2 along the first direction and presses the busbar 1 against the structural body 2 along the second direction. The limiting unit can restrict the displacement of the limiting member 3 in the first direction. The structural body 2 is provided with a first limiting part and a second limiting part. The first limiting part can restrict the displacement of the busbar 1 in the first direction, and the second limiting part and the limiting member 3 can restrict the displacement of the busbar 1 in the third direction.

[0058] Therefore, by using the first limiting part and the second limiting part provided on the structural body 2, and in cooperation with the limiting member 3 and the limiting unit, the busbar 1 can be limited on the structural body 2, thereby simplifying the assembly process and facilitating the installation of the busbar 1.

[0059] It should be noted that in this embodiment, the first direction refers to the length direction of the structural body 2, the second direction refers to the width direction of the structural body 2, and the third direction refers to the height direction of the structural body 2.

[0060] Based on the above general introduction, specifically, the busbar 1 in this embodiment is also provided with a battery cell terminal observation hole 12 and a foolproof hole 13.

[0061] The cell terminal observation hole 12 is used to directly observe the cell terminal from above the busbar 1, checking whether it is aligned, fully welded, free of incomplete welds, and without misalignment. This facilitates rapid quality inspection by the equipment and also serves as a visual positioning reference, ensuring that the welding path is accurately aligned with the center of the terminal, avoiding weld deviation, and thus improving production efficiency. The anti-misalignment hole 13 is used to prevent the busbar 1 from being installed backwards or misaligned, thereby improving the yield rate and further improving production efficiency. The specific structures of the cell terminal observation hole 12 and the anti-misalignment hole 13 in this embodiment can be referred to as existing cell terminal observation holes 12 and anti-misalignment holes 13, and will not be described in detail here.

[0062] Combination Figure 1 , Figure 2 , Figure 6 as well as Figure 7 As shown, in some exemplary embodiments, the first limiting part includes a limiting protrusion 21 provided on the structural body 2. The limiting protrusion 21 protrudes along a second direction and is spaced apart from the limiting member 3 in a third direction. This arrangement enables the busbar 1 to be limited in a third direction. At the same time, its structure is simple, easy to manufacture, and also helps to reduce costs.

[0063] Combination Figure 1 , Figure 2 , Figure 6 as well as Figure 7 As shown, in some exemplary embodiments, the second limiting part includes a limiting block 22 disposed on the structural body 2. The limiting block 22 can be inserted into the limiting groove of the busbar 1 in a third direction and restrict the displacement of the busbar 1 in the first direction. Thus, by providing a limiting block 22 inserted into the structural body 2 in a third direction, it is possible to ensure the reliable positioning of the limiting block 22 while also making the busbar 1 easy to disassemble, thereby facilitating the disassembly and maintenance of the busbar 1, which in turn helps to improve the production efficiency of the busbar 1 assembly and reduce production costs.

[0064] Combination Figure 1 , Figure 2 , Figure 6 as well as Figure 7 As shown, in some exemplary embodiments, both the limiting protrusion 21 and the limiting member 3 are elongated strips extending along the first direction, and multiple limiting blocks 22 are spaced apart along the first direction. Thus, the elongated limiting protrusion 21 and the limiting member 3 can generate a larger contact area with the busbar 1, avoiding stress concentration. Simultaneously, the multiple limiting blocks 22 spaced apart along the first direction effectively restrict the position of each busbar 1 in the first direction, facilitating subsequent welding processes, thereby reducing production difficulty and further reducing production costs.

[0065] Combination Figure 2 as well as Figure 13 As shown, in some exemplary embodiments, the structural body 2 is provided with a recessed relief groove 23 along the second direction, which is used to avoid the bent portion 11 on the busbar 1. This arrangement can prevent the stamped bend on the busbar 1 from interfering with the busbar 1 support, thereby preventing the busbar 1 from failing to fit tightly with the busbar 1 support.

[0066] Combination Figures 1 to 4 as well as Figure 6 , Figure 11 , Figure 12 As shown, in some exemplary embodiments, the limiting unit includes a stop block 24 and a limiting slider 4 respectively disposed at both ends of the structural body 2 in a first direction. The limiting slider 4 is inserted into the structural body 2 in a third direction and abuts against both ends of the limiting member 3 with the stop block 24. This arrangement can achieve limiting in the first direction and ensure the structural strength of the busbar mounting structure. At the same time, the limiting slider 4 inserted into the structural body 2 in a third direction can achieve reliable connection and facilitate disassembly, thereby facilitating the disassembly and maintenance of the busbar 1 and improving the production efficiency of the busbar 1 assembly.

[0067] Figures 2 to 4 as well as Figures 8 to 12 As shown, in some exemplary embodiments, a fastener 5 is screwed between the limiting slider 4 and the limiting member 3, and the fastener 5 connects the limiting slider 4 and the limiting member 3 together along a first direction. This arrangement ensures the reliability of the connection of the limiting slider 4, thereby preventing the limiting slider 4 from dislodging due to vibration or impact, thus improving safety performance. At the same time, the screwed connection method not only achieves a reliable connection but also facilitates disassembly, which is beneficial for the disassembly and maintenance of the busbar 1, and further improves the production efficiency of the busbar 1 assembly.

[0068] In specific implementation, the limiting member 3 is provided with a screw hole 34, while the limiting slider 4 is provided with a clearance hole 42. The fastener 5 passes through the clearance hole 42 on the limiting slider 4 and is screwed into the screw hole 34 on the limiting member 3, thereby limiting the limiting slider 4 in a third direction. It is worth mentioning that the fastener 5 in this embodiment is a bolt, which is well known to those skilled in the art, and will not be described in detail here.

[0069] Combination Figures 11 to 12 As shown, in some exemplary embodiments, the limiting slider 4 is provided with a limiting portion 41, which presses the busbar 1 against the structural body 2 along the second direction. This configuration can improve the positioning reliability of the busbar 1, ensure that the busbar 1 is firmly fixed in the second direction, and cooperate with other limiting components to form multi-directional limiting of the busbar 1, preventing the busbar 1 from loosening or shaking in any direction.

[0070] Continue to combine Figure 2 , Figure 4 , Figures 8 to 10 As shown, in some exemplary embodiments, the limiting member 3 includes a main body 31 and a protrusion 32 protruding from one side of the main body 31 along the second direction. The structural body 2 is provided with a groove 25, in which the protrusion 32 is inserted. A limiting notch 33 is provided on the side of the main body 31 opposite to the second limiting part. One sidewall of the limiting notch 33 abuts against the side of the busbar 1, and the other sidewall of the limiting notch 33 abuts against the end face of the busbar 1. This configuration ensures reliable positioning of the busbar 1 in the first and second directions while facilitating disassembly and maintenance of the busbar 1, thereby improving the production efficiency of the busbar 1 assembly.

[0071] In this embodiment, during the bus installation structure, specifically when the bus 1 is installed onto the structural body 2 that supports the bus 1, the limiting block 22 is inserted into the limiting groove of the bus 1 and can limit the displacement of the bus 1 in the first direction. At the same time, the limiting protrusion 21 protruding along the second direction is used to limit the displacement of the bus 1 in the first direction.

[0072] Subsequently, the limiting member 3 is inserted into the structural body 2 along the first direction. Specifically, the limiting member 3 includes a main body 31 and a protrusion 32 protruding from one side of the main body 31 along the second direction. The structural body 2 is provided with a groove 25, and the protrusion 32 is inserted into the groove 25. The main body 31 is provided with a limiting notch 33 on the side opposite to the second limiting part. One side wall of the limiting notch 33 abuts against the side of the busbar 1, and the other side wall of the limiting notch 33 abuts against the end face of the busbar 1. One side of the main body 31 abuts against the stop block 24 located at one end of the structural body 2. At this time, the limiting member 3 can press the busbar 1 against the structural body 2 along the second direction and can cooperate with the limiting block 22 to limit the displacement of the busbar 1 in the third direction.

[0073] Furthermore, the limiting slider 4 is inserted into the structural body 2 along the third direction. At this time, the limiting slider 4 and the stop block 24 respectively abut against the two ends of the limiting member 3, thereby limiting the limiting member 3 in the first direction. Finally, the limiting slider 4 and the limiting member 3 are connected together by the fastener 5 along the first direction, thereby limiting the limiting slider 4 in the third direction.

[0074] When it is necessary to disassemble and repair the bus installation structure of this embodiment, simply remove the fastener 5 to remove the limiting slider 4. After removing the limiting slider 4, the limiting member 3 can be removed from the slide groove 25, and then the bus 1 can be adjusted.

[0075] It should be noted that any related structures not mentioned in this embodiment can be referred to as those well known to those skilled in the art, and will not be described in detail here.

[0076] It is worth noting that, regarding this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still... Figures 1 to 13 As shown, it may include, for example, a structural body 2 for carrying the busbar 1, and a limiting member 3 and a limiting unit disposed on the structural body 2.

[0077] The limiting member 3 is inserted into the structural body 2 along the first direction and presses the busbar 1 against the structural body 2 along the second direction. The limiting unit can restrict the displacement of the limiting member 3 in the first direction. The structural body 2 is provided with a first limiting part and a second limiting part. The first limiting part can restrict the displacement of the busbar 1 in the first direction, and the second limiting part and the limiting member 3 can restrict the displacement of the busbar 1 in the third direction. The first limiting part includes a limiting protrusion 21 provided on the structural body 2. The limiting protrusion 21 protrudes along the second direction and is spaced apart from the limiting member 3 in the third direction.

[0078] The second limiting part includes a limiting block 22 disposed on the structural body 2. The limiting block 22 can be inserted into the limiting groove of the busbar 1 along a third direction and restricts the displacement of the busbar 1 in the first direction. The limiting protrusion 21 and the limiting member 3 are both elongated strips extending along the first direction, and there are multiple limiting blocks 22 spaced apart along the first direction. The structural body 2 is provided with a relief groove 23 that is recessed in the second direction. The relief groove 23 is used to avoid the bent portion 11 on the busbar 1.

[0079] The limiting unit includes a stop block 24 and a limiting slider 4 respectively disposed at both ends of the structural body 2 in the first direction. The limiting slider 4 is inserted into the structural body 2 in the third direction and abuts against both ends of the limiting member 3 with the stop block 24. A fastener 5 is screwed between the limiting slider 4 and the limiting member 3, and the fastener 5 connects the limiting slider 4 and the limiting member 3 together in the first direction.

[0080] The limiting slider 4 is provided with a limiting part 41, which presses the busbar 1 against the structural body 2 along the second direction. The limiting member 3 includes a main body 31 and a protrusion 32 protruding from one side of the main body 31 along the second direction. The structural body 2 is provided with a sliding groove 25, in which the protrusion 32 is inserted. The main body 31 is provided with a limiting notch 33 on the side opposite to the second limiting part. One side wall of the limiting notch 33 abuts against the side of the busbar 1, and the other side wall of the limiting notch 33 abuts against the end face of the busbar 1.

[0081] In the preferred embodiment of the busbar installation structure above, the specific setting and arrangement of the first limiting part, the second limiting part, the limiting slider 4 and the limiting member 3, etc., can still be referred to the description in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the first limiting part, the second limiting part, the limiting slider 4 and the limiting member 3, etc., can also be referred to the description in the above exemplary embodiments.

[0082] The busbar installation structure of this embodiment adopts the above design. Through the first limiting part and the second limiting part provided on the structure body 2, and in cooperation with the limiting member 3 and the limiting unit, the busbar 1 can be limited on the structure body 2. The limiting member 3 inserted on the structure body 2 can simplify the assembly process and facilitate the installation of the busbar 1.

[0083] An embodiment of the second aspect of this application provides a battery pack having a bus mounting structure as described above.

[0084] The battery pack of this application, by setting the busbar mounting structure as described above, can limit the busbar 1 on the structure body 2, thereby simplifying the assembly process, facilitating the installation of the busbar 1, and enabling the busbar 1 to be repaired. This helps to reduce the difficulty of battery pack production, thereby reducing production costs and further enhancing the market competitiveness of the battery pack.
