Description

Technical Field

[0001] This utility model relates to the field of new energy battery pack technology, specifically to a BMS bracket for platform-based PDUs. Background Technology

[0002] In the current era of rapid development in the new energy vehicle industry, the battery pack, as the core power source of new energy vehicles, directly affects the overall vehicle operation in terms of performance and safety. The PDU (Power Distribution Unit), as a key component for the distribution and management of electrical energy within the battery pack, plays a crucial role in rationally allocating the battery pack's energy to various electrical modules within the vehicle. The rationality of its design has a significant impact on the overall performance, space utilization, and cost control of the battery pack.

[0003] Meanwhile, the BMS (Battery Management System), as a core component for monitoring and managing battery status, works in conjunction with the PDU to ensure the safe and stable operation of the battery pack.

[0004] However, current PDU design processes must consider various factors, including existing battery pack structures, customer-specific requirements, and end-of-line (EOL) testing. Because different suppliers' BMSs differ in structural dimensions, interface definitions, and functional implementations, and because different customers have varying needs regarding vehicle performance, functional configurations, and cost budgets, different customers often require different BMS design solutions. This situation has directly led to a significant increase in the types of BMS available.

[0005] The design and production of BMS requires a significant investment of R&D resources, mold costs, and production equipment. This not only results in serious resource waste but also significantly increases development costs and prolongs the product development cycle. Consequently, it makes it difficult for companies to respond quickly to market demands and gain a cost and efficiency advantage in the fierce market competition. Utility Model Content

[0006] The present invention aims to provide a BMS bracket for platform-based PDUs to solve the problem that existing BMS brackets have poor versatility and cannot adapt to the installation of different BMS.

[0007] To solve the above problems, the present invention adopts the following technical solution: a BMS bracket for platform-based PDUs, 1. comprising a mounting frame, wherein the two opposite sides of the mounting frame are a connecting surface and a mounting surface, the mounting surface being used to mount the BMS; the area of ​​the mounting surface is greater than or equal to the bottom area of ​​the BMS to be mounted;

[0008] The mounting surface is divided into a first region, a second region and a third region from left to right. Each region is provided with a number of mounting holes that can be selected to fix the BMS. The mounting holes include a first mounting hole, a second mounting hole and a third mounting hole from left to right.

[0009] The first mounting hole is located on both sides of the first region and forms a first curved arc segment that gradually extends to both sides; the second mounting hole is located on both sides of the second region and forms a second curved arc segment that gradually extends upward; the third mounting hole is located on both sides of the third region and forms a third curved arc segment that gradually extends upward.

[0010] The first region, the second region, and the third region are all provided with weight-reducing holes for the weight-reducing mounting bracket;

[0011] The connecting surface is provided with a press-fit nut corresponding to the mounting hole, and the mounting hole is provided with a matching mounting bolt. The mounting bolt passes through the mounting hole and cooperates with the press-fit nut to fix the BMS on the mounting surface.

[0012] The principle of this solution is as follows: Before installing the BMS, accurately select the appropriate BMS model and matching mounting bolts according to actual needs. During installation, first, pass the selected mounting bolts sequentially through the pre-set mounting holes. Then, connect the mounting bolts through the mounting holes with the corresponding rivet nuts. The rivet nuts have reliable locking performance; after the mounting bolts and rivet nuts are tightened, a stable connection structure is formed, firmly fixing the BMS to the mounting surface.

[0013] This installation method is not only simple and easy to operate, but also effectively ensures the stability and firmness of the BMS after installation, preventing it from loosening or shifting due to vibration, impact or other factors during use, thus providing a solid installation guarantee for the normal operation of the BMS.

[0014] The advantages of this solution are: (1) This solution breaks the technical prejudice that "BMS brackets need to be customized". In the existing technology, due to the differences in structural size, interface definition and function implementation of BMS from different suppliers, different types of BMS brackets are required. This solution directly realizes the stable connection between BMS and mounting surface through the distribution and layout of mounting holes and the universal fixing logic of "mounting bolts + rivet nuts + mounting holes", eliminating the unnecessary intermediate component of "custom brackets" and realizing the unity of structural simplification and functional enhancement.

[0015] (2) This solution can be adapted to various BMS models by setting up “mounting bolts + rivet nuts + mounting holes” (only matching the corresponding mounting holes is required), which reduces the types of parts, reduces the complexity and cost of BMS bracket development, improves the adaptability to BMS model iteration, and significantly reduces the installation difficulty and improves the assembly efficiency.

[0016] (3) In addition, this solution takes into account both weight and versatility. The setting of weight-reducing holes effectively reduces the amount of material used, reduces the overall weight of the bracket while ensuring load-bearing capacity, and provides a heat circulation channel for the BMS, which helps to accelerate air convection, improve the local high temperature environment, and prevent electrical connection failure or material aging caused by excessive temperature, thereby improving the stability and service life of the BMS.

[0017] Preferably, as an improvement, the weight reduction hole includes a first weight reduction hole located in the middle of the first region, a second, third and fourth weight reduction holes located in the middle of the second region, and a fifth weight reduction hole located in the middle of the third region;

[0018] The first mounting hole is located on the upper and lower sides of the first weight reduction hole, and the positions of the first mounting holes in the vertical direction are on the same axis; the second mounting hole is located on the upper and lower sides of the third weight reduction hole, and the positions of the second mounting holes in the vertical direction are on the same axis; the third mounting hole is located on the upper and lower sides of the fifth weight reduction hole, and the positions of the third mounting hole in the vertical direction are on the same axis.

[0019] Beneficial effects: The zoned arrangement of weight-reducing holes in this design effectively reduces the overall weight, meeting the requirements of lightweight design. Simultaneously, the mounting holes are located on the upper and lower sides of the weight-reducing holes, avoiding the core area, ensuring sufficient structural material is retained at the mounting points. This prevents weakening of the connection points due to excessive weight reduction, achieving "weight reduction without sacrificing strength." The first, second, and third mounting holes are coaxially distributed along the vertical direction of their corresponding weight-reducing holes. This axial alignment design significantly improves positioning accuracy during installation, ensures uniform stress on the connectors, enhances connection stability and reliability, and effectively prevents loosening or damage caused by uneven loading or misalignment.

[0020] Preferably, as an improvement, the number of first mounting holes in the first region is at least two, the number of second mounting holes in the second region is at least two, and the number of third mounting holes in the third region is at least two.

[0021] Beneficial effects: The combination of at least two mounting holes has a clear geometric positioning relationship (such as axis alignment), which can effectively limit the translational and rotational degrees of freedom of the BMS in the mounting surface, ensure the accuracy and repeatability of the component installation position, prevent offset, tilting or misalignment during installation, and ensure assembly quality.

[0022] Preferably, as an improvement, it further includes an integrally formed connecting frame and a limiting frame; the connecting frame is located at the top of the mounting frame and extends toward the connecting surface, and the limiting frame is located at the bottom of the mounting frame and extends toward the mounting surface.

[0023] Beneficial effects: (1) The connecting frame, the limiting frame, and the mounting frame are integrally formed, avoiding assembly errors and loose connections caused by splicing multiple parts. The overall structure is more stable and can effectively improve the load-bearing capacity and deformation resistance of the BMS. (2) The limiting frame plays a guiding and limiting role during installation, ensuring that the BMS is accurately positioned. (3) The connecting frame and the limiting frame are located at the top and bottom of the mounting frame, respectively, forming an upper and lower support structure, which can effectively distribute external loads.

[0024] Preferably, as an improvement, the connecting frame is provided with a first connecting hole, and the limiting frame is provided with a second connecting hole. A matching first bolt is provided in the first connecting hole, and a matching second bolt is provided in the second connecting hole, so as to fix the BMS bracket on the PDU.

[0025] Beneficial effects: The use of double bolt connection (first bolt + second bolt) enhances the stability of the overall structure and can prevent the support from loosening due to vibration or external force.

[0026] Preferably, as an improvement, the connecting frame is a type 7 structure, which includes a longitudinal plate and a transverse plate. One end of the longitudinal plate is fixedly connected to one end of the transverse plate, and the longitudinal plate and the transverse plate are perpendicular to each other. The first connecting hole is located on the transverse plate.

[0027] Beneficial effects: The Type 7 structure, through the vertical connection of longitudinal and transverse plates, forms a Type 7 support structure with excellent bending and torsional resistance, effectively supporting the weight of the BMS bracket and the BMS itself. Simultaneously, it allows the connecting frame to fit more closely to the PDU's base mounting surface, maintaining a certain distance between the BMS bracket's connecting surface and the base mounting surface. This avoids spatial interference between the BMS and other internal components of the PDU, while also providing operating space for heat dissipation around the BMS. The design of the first connecting hole position facilitates quick location by operators, reducing the difficulty of hole alignment.

[0028] Preferably, as an improvement, a transition portion is provided at the connection between the longitudinal plate and the transverse plate, the transition portion being a rounded corner with a radius of 1-3 mm.

[0029] Beneficial effects: The design of the transition section can effectively disperse stress, making the load more evenly distributed at the connection, and can reduce the risk of local deformation and cracking, thereby improving the fatigue resistance and load-bearing capacity of the overall structure.

[0030] Preferably, as an improvement, the limiting frame has a rectangular structure, and the limiting frame and the mounting frame are connected by an arc transition.

[0031] Beneficial effects: The curved transition effectively alleviates stress concentration, resulting in a more even distribution of force and reducing the risk of crack initiation, thereby improving the overall load-bearing capacity and service life of the structure. It also eliminates sharp edges, reducing the risk of scratches or cuts caused by collisions or contact.

[0032] Preferably, as an improvement, the distance between the second connecting hole and the mounting surface is 45mm-50mm.

[0033] Beneficial effects: Spacing settings are mainly used to provide suitable installation conditions for the BMS, ensuring that the BMS can be installed accurately and stably in the specified location.

[0034] Preferably, as an improvement, the weight-reducing hole is square.

[0035] Beneficial effects: Square holes have a larger opening area and edge length, providing better airflow channels at the same density. They can effectively guide airflow through the interior or surrounding area, accelerate heat dissipation, and prevent local overheating.

[0036] The beneficial effects of this solution are: (1) The ingenious design of the BMS support structure in this solution not only effectively ensures the overall stability and reliability of the support, but also gives the support good mechanical strength and lightweight characteristics. At the same time, while ensuring the rationality of the structure, it maximizes the compatibility with the installation requirements of different BMS, and is both practical and economical.

[0037] (2) The mounting holes in this solution are designed and distributed in a targeted manner. Through clever layout, multiple sets of mounting points with different spacings are formed, which can match the different requirements of different BMS in terms of hole spacing. At the same time, the setting and distribution of weight-reducing holes provide sufficient guarantee for the heat dissipation requirements of different BMS. The first to fifth weight-reducing holes can flexibly adapt to different heat dissipation paths according to the size of the BMS and the heat generation area.

[0038] (3) In this scheme, the weight reduction holes are set to achieve structural lightweighting while also taking into account heat dissipation optimization and mechanical performance improvement.

[0039] (4) The structural design of the connecting frame in this solution realizes the gap connection between BMS and PDU. While satisfying its own space layout, this design also fully considers the rationality of the overall layout of PDU, and provides effective installation points for peripheral components (such as wire harnesses), thereby improving the high integration level of the entire battery pack and effectively reducing space occupation.

Detailed Implementation

[0052] The following detailed description illustrates the specific implementation method:

[0053] The implementation examples are basically as follows Figure 1 As shown: A BMS bracket for platform-based PDUs includes an integrally molded mounting bracket 1, a connecting bracket 2, and a limiting bracket 3; the connecting bracket 2 is located at the top of the mounting bracket 1, and the limiting bracket 3 is located at the bottom of the mounting bracket 1. The integrally molded structure design of the BMS bracket can effectively improve the overall strength and rigidity of the bracket, thereby enhancing the overall stability and reliability of the bracket. Specifically, in this embodiment, the BMS bracket is laser-cut, bent, and finally riveted with a riveting nut. The BMS bracket is made of DC01 material, with an outer envelope dimension of 390mm*148.5mm*68.5mm, a thickness of 1.5mm, and a total weight of 0.5740kg. The material composition and mechanical properties of the selected DC01 material meet the requirements of Q / BQB 408.

[0054] Specifically,

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the mounting bracket 1 is the main support structure used to install and support the BMS4. The two opposite sides of the mounting bracket 1 are a connecting surface 110 and a mounting surface 120. The area of ​​the mounting surface 120 is greater than or equal to the bottom area of ​​the BMS4 to be installed. Several mounting holes 130 are provided on the upper and lower sides of the mounting surface 120, and rivet nuts 140 corresponding to the mounting holes 130 are installed on the connecting surface 110. During installation, by passing the mounting bolts sequentially through the mounting holes 130 and engaging with the corresponding rivet nuts 140, the BMS4 is securely fixed to the mounting surface 120.

[0056] Specifically, the mounting surface 120 is divided into a first region, a second region, and a third region from left to right. Each region is equipped with several mounting holes 130 for fixing the BMS4. The mounting holes 130 include a first mounting hole 1301, a second mounting hole 1302, and a third mounting hole 1303 from left to right. The first mounting hole 1301 is located on both sides of the first region and has a first curved arc segment that gradually extends to both sides. The second mounting hole 1302 is located on both sides of the second region and has a second curved arc segment that gradually extends upward. The third mounting hole 1303 is located on both sides of the third region and has a third curved arc segment that gradually extends upward.

[0057] In addition, the first, second, and third regions are each provided with several weight-reducing holes 150 for reducing the weight of the mounting bracket 1, which reduces the overall weight of the BMS bracket and saves overall materials, while ensuring effective support for the BMS. Specifically, the weight-reducing holes 150 are square, including a first weight-reducing hole 1501 located in the middle of the first region, a second weight-reducing hole 1502, a third weight-reducing hole 1503 and a fourth weight-reducing hole 1504 located in the middle of the second region, and a fifth weight-reducing hole 1505 located in the middle of the third region.

[0058] The first mounting hole 1301 is located on the upper and lower sides of the first weight reduction hole 1501, and the holes of the first mounting hole 1301 in the vertical direction are on the same axis. The second mounting hole 1302 is located on the upper and lower sides of the third weight reduction hole 1503, and the holes of the second mounting hole 1302 in the vertical direction are on the same axis. The third mounting hole 1303 is located on the upper and lower sides of the fifth weight reduction hole 1505, and the holes of the third mounting hole 1303 in the vertical direction are on the same axis.

[0059] The first region has at least two first mounting holes 1301, the second region has at least two second mounting holes 1302, and the third region has at least two third mounting holes 1303. Specifically, in this embodiment, the number of first mounting holes 1301 is 6, the number of second mounting holes 1302 is 8, and the number of third mounting holes 1303 is 6.

[0060] Furthermore, in this embodiment, from left to right, the hole spacing of the first mounting hole 1301 along the same axis in the vertical direction is 80mm, 85mm, and 105mm respectively; the hole spacing of the second mounting hole 1302 along the same axis in the vertical direction is 85mm, 85mm, 80mm, and 86mm respectively; and the hole spacing of the third mounting hole 1303 along the same axis in the vertical direction is 105mm, 85mm, and 86mm respectively.

[0061] The setting and distribution of mounting holes 130 precisely meet the differentiated needs of different BMS4 models in terms of hole spacing. Whether it is the hole position adjustment caused by functional iteration of different BMS4 models, or the change of fixing point due to size difference in the same series of products, stable fixing can be achieved by selecting matching combinations of mounting holes 130 (such as close combination of first mounting hole 1301 and second mounting hole 1302, medium-distance combination of second mounting hole 1302 and third mounting hole 1303, or far-distance combination of first mounting hole 1301 and third mounting hole 1303, etc.), without any modification to the basic structure.

[0062] Meanwhile, the placement and distribution of the weight-reducing holes 150 provide ample assurance for the heat dissipation needs of different BMS4s. Different specifications of BMS4s have different layouts of heat-generating components and designs for heat dissipation channels. The first weight-reducing hole 1501 to the fifth weight-reducing hole 1505, arranged from left to right, can flexibly adapt to different heat dissipation paths according to the size of the BMS4 and the heat-generating area. For example, a small BMS4 can efficiently dissipate heat using the area surrounding the middle third weight-reducing hole 1503, while a large BMS4 can form a through-flow airflow channel through multiple sets of weight-reducing holes 150, preventing heat accumulation in the installation area. Furthermore, the distribution of mounting holes 130 and weight-reducing holes 150 creates a synergistic effect of "functional complementarity": while the mounting holes 130 meet the fixing requirements, their correspondence with the weight-reducing holes 150 (such as the mounting holes 130 being located on the upper and lower sides of the weight-reducing holes 150) avoids the fixing structure from obstructing the heat dissipation space of the weight-reducing holes 150; while the weight-reducing holes 150, based on the reserved heat dissipation channel, play a role in weight reduction, which can reduce materials, realize the overall lightweight design of the bracket, and further improve the adaptability and convenience of installing different BMS4.

[0063] In this embodiment, the dimensions of the first weight-reduction hole 1501 are 30mm*40mm, the second weight-reduction hole 1502 are 90mm*72mm, the third weight-reduction hole 1503 are 35mm*40mm, the fourth weight-reduction hole 1504 are 65mm*72mm, and the fifth weight-reduction hole 1505 are 23mm*40mm. This design not only effectively reduces the weight of the BMS bracket but also meets the requirements of structural strength and material saving, while ensuring good support performance for the BMS.

[0064] like Figure 5 As shown, the connecting bracket 2 is located at the top of the mounting bracket 1 and extends towards the connecting surface 110, while the limiting bracket 3 is located at the bottom of the mounting bracket 1 and extends towards the mounting surface 120. The connecting bracket 2 is provided with a first connecting hole 5, and the limiting bracket 3 is provided with a second connecting hole 6. A matching first bolt is disposed in the first connecting hole 5, and a matching second bolt is disposed in the second connecting hole 6, thereby fixing the BMS bracket to the PDU.

[0065] Specifically, such as Figure 6 As shown, the connecting frame 2 has a type 7 structure, which includes a longitudinal plate 220 and a transverse plate 210. One end of the longitudinal plate 220 is fixedly connected to one end of the transverse plate 210, and the longitudinal plate 220 and the transverse plate 210 are perpendicular to each other. A transition portion 230 is provided at the connection between the longitudinal plate 220 and the transverse plate 210. This transition portion 230 is a rounded corner with a radius of 1-3 mm, which can effectively disperse stress and avoid material fatigue fracture caused by sharp corners, thereby enhancing the fatigue resistance of the structure.

[0066] Furthermore, the first connecting hole 5 is located on the transverse plate 210. The design of the position of the first connecting hole 5 not only ensures that the connecting frame 2 can be stably connected to other components, but also facilitates precise positioning and operation during the assembly process. At the same time, it improves the stability and reliability of the overall structure, while helping to maintain the compactness and aesthetics of the structure.

[0067] In this embodiment, the width of the connecting bracket 2 extending toward the connecting surface 110 is 20mm, so that the connecting surface 110 of the BMS bracket and the base mounting surface (i.e. the base mounting surface of the PDU enclosure) maintain a certain distance. This can not only avoid spatial interference between the BMS4 and other components inside the PDU, but also reserve operating space for heat dissipation around the BMS. At the same time, it can avoid space waste caused by excessive size.

[0068] like Figure 7 As shown, the limiting frame 3 has a rectangular structure, which not only provides a stable support base but also facilitates installation with other components. The limiting frame 3 and the mounting frame 1 use an arc-shaped transition connection, which effectively reduces stress concentration, enhances the overall structural strength, and makes the connection smoother and more natural, improving assembly fluidity. Furthermore, the distance between the second connecting hole 6 and the mounting surface 120 is 45mm-50mm, mainly used to provide suitable installation conditions for the BMS4, ensuring that the BMS4 can be accurately and stably installed in the designated position. When part of the BMS4 is installed, the bottom end of the BMS4 will form a tight contact with the upper surface of the limiting frame 3. This contact method can evenly transfer the force borne by the BMS4 to the limiting frame 3. With the support of the limiting frame 3, it effectively prevents the BMS4 from shaking or shifting during use, thus ensuring the support stability of the BMS4 after installation and providing a reliable structural guarantee for its normal operation.

[0069] Specific implementation process:

[0070] like Figure 8 , Figure 9 , Figure 10 , Figure 11As shown, before performing the BMS4 installation operation, the appropriate model of BMS4 and the matching mounting bolts should be accurately selected according to the actual needs.

[0071] During installation, firstly, the selected mounting bolts are passed sequentially through the preset mounting holes 130. Then, the mounting bolts passing through the mounting holes 130 are engaged with the corresponding rivet nuts 140. The rivet nuts 140 have reliable locking performance. When the mounting bolts and rivet nuts 140 are tightened, a stable connection structure is formed, firmly fixing the BMS4 to the mounting surface 120.

[0072] This installation method is not only simple and easy to operate, but also effectively ensures the stability and firmness of the BMS4 after installation, preventing it from loosening or shifting due to vibration, impact or other factors during use, thus providing a solid installation guarantee for the normal operation of the BMS4.

[0073] In summary, this solution breaks the technical prejudice that "BMS brackets need to be customized." In existing technologies, due to differences in structural dimensions, interface definitions, and functional implementations among BMS from different suppliers, different types of BMS brackets are required. This solution directly achieves a stable connection between the BMS4 and the mounting surface 120 through a universal fixing logic of "mounting bolts + rivet nuts 140 + mounting holes 130," eliminating the unnecessary intermediate component of "customized brackets" and achieving a balance between structural simplification and functional enhancement. It is also compatible with multiple BMS4 models (only requiring matching of the corresponding mounting holes 130), reducing the number of parts, lowering the complexity and cost of BMS bracket development, improving adaptability to BMS model iterations, significantly reducing installation difficulty, and increasing assembly efficiency.

[0074] Furthermore, through the ingenious design of the BMS support structure, this solution not only effectively ensures the overall stability and reliability of the support, but also gives the support good mechanical strength and lightweight characteristics. At the same time, while ensuring structural rationality, it maximizes compatibility with the installation requirements of different BMS4, combining practicality and economy.
