[0002] The power battery is the power source that provides power to the tool. In related technologies, the power battery is arranged in a compact structure, which results in the high-voltage busbar and the low-voltage connection harness being close to each other. At this time, the high-voltage busbar not only interferes with the signal of the low-voltage harness, affecting the accuracy of low-voltage acquisition, but also conducts heat to the low-voltage harness shell, leading to thermal runaway. There is also the risk that the positive and negative terminals of the high-voltage line are close to each other, and if the voltage is high, they will interfere with each other, break down the positive and negative terminals, and cause a short circuit. Summary of the Invention

[0011] According to some embodiments of this application, the base plate is provided with an anti-misassembly notch, which is located in the second region or the fourth region.

[0012] According to some embodiments of this application, the first and second partitions are composite layer structures, comprising: a first wear-resistant layer, an electromagnetic shielding layer, a heat-insulating core layer, and a second wear-resistant layer.

[0024] In related technologies, the high-voltage busbar and low-voltage connection harness of the power battery bracket are positioned close to each other. When the high-voltage busbar is energized, it causes electromagnetic interference to the low-voltage harness, significantly reducing the accuracy of the low-voltage harness's data acquisition. This results in inaccurate information processing by the Battery Management System (BMS), preventing it from properly adjusting the battery state and leading to a significant reduction in battery life. Furthermore, the high-voltage busbar generates a large amount of heat when energized. If it is too close to the low-voltage harness, the heat can be transferred to the surface of the low-voltage harness, posing a risk of thermal runaway. Additionally, the close proximity of the positive and negative terminals of the high-voltage circuit can lead to insulation failure, causing breakdown between the positive and negative terminals, forming a closed loop inside the battery, resulting in a short circuit and ultimately rendering the battery unusable.

[0025] This application provides an integrated power battery bracket.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] According to some embodiments of this application, such as Figures 1 to 6 As shown, this application provides an integrated power battery bracket, including: a base plate 1, a first separator 2, a second separator 3, a threaded bushing 4, and a snap fastener 5. The first separator 2 and the second separator 3 are disposed on the base plate 1, perpendicular to the base plate 1. The vertical structure of the separators guides heat from the high-voltage area to be conducted outward through the heat dissipation channels of the base plate, preventing heat accumulation in the low-voltage area while maintaining the heat dissipation efficiency of the high-voltage area, thus achieving precise control of thermal management. The second separator 3 intersects with the first separator 2, dividing the base plate 1 into a first region A1, a second region A2, a third region A3, and a fourth region A4. The threaded bushing 4 is disposed within the first region A1 and the third region A3, and is suitable for providing mounting positions for the high-voltage busbar 13. The snap fastener 5 is disposed within the second region A2 and the fourth region A4, and is suitable for constraining the low-voltage wiring harness 14. The voltage of the high-voltage busbar 13 is higher than that of the low-voltage wiring harness 14. The first partition 2 and the second partition 3 are configured to prevent the heat of the high-voltage busbar 13 from being transferred to the second region A2 and the fourth region A4, and to prevent the electromagnetic field of the high-voltage busbar 13 from being propagated to the second region A2 and the fourth region A4.

[0029] In this embodiment, by setting intersecting first partition 2 and second partition 3 on the base plate 1, four relatively isolated areas are defined. The first partition 2 and second partition 3 are used to eliminate the influence of the high-voltage busbar 13 on the low-voltage wiring harness 14, and to eliminate the mutual influence between the positive and negative terminals of the high-voltage busbar 13. This physical separation effectively blocks the conduction path of heat generated by the high-voltage components to the low-voltage area, significantly reducing the aging rate of the low-voltage wiring harness due to high temperature and improving system reliability. This application is the first to integrate the functions of thermal management, electromagnetic shielding, structural integration and safety protection into a single bracket structure, breaking through the limitations of traditional discrete designs; combining the physical barrier of the partition and the characteristics of the electromagnetic shielding material, a dual guarantee of active heat dissipation and passive isolation is formed, significantly improving the comprehensiveness of the technical effect; by solving the coupling problem between the high-voltage and low-voltage systems through structural design, it not only meets the single functional requirements, but also optimizes the overall performance and safety of the vehicle electrical system, which is in line with the development trend of new energy vehicles for high integration and high reliability.

[0030] According to some embodiments of this application, the first partition 2 and the second partition 3, as key structural components of the support, are securely mounted on the base plate 1, and both are perpendicular to the base plate 1 to ensure structural stability and isolation effect. The second partition 3 intersects the first partition 2 at a certain angle, forming four distinct areas: the first area A1, the second area A2, the third area A3, and the fourth area A4. This layout not only achieves effective isolation between the high-voltage busbar 13 and the low-voltage wiring harness 14, but also reduces the possibility of electromagnetic interference and heat conduction through physical separation. Specifically, the first area A1 and the third area A3 are designed as the installation areas for the high-voltage busbar 13, while the second area A2 and the fourth area are used to arrange the low-voltage wiring harness 14, thereby achieving complete spatial isolation between high and low voltage. Through physical separation, the electromagnetic field and heat generated by the high-voltage busbar 13 are effectively prevented from diffusing into the low-voltage wiring harness 14 area, protecting the low-voltage wiring harness 14 from interference.

[0031] According to some embodiments of this application, optionally, in general, the first partition 2 and the second partition 3 are arranged perpendicular to each other, which has strong applicability. In special cases, for example, if the size of the high-voltage busbar 13 is large, the included angle between the first partition 2 and the second partition 3 can be appropriately adjusted to increase the area of ​​the first region A1 and the third region A3 to meet the size of the high-voltage busbar 13.

[0032] According to some embodiments of this application, threaded bushings 4, as dedicated mounting components for the high-voltage busbar 13, are positioned within the first region A1 and the third region A3. These bushings not only provide a secure mounting point but also ensure a reliable connection between the high-voltage busbar 13 and the bracket through their precise thread design. Optionally, the threaded bushing 4 includes an inner liner and an outer liner. The inner liner is made of metal (e.g., stainless steel, copper, copper alloy, etc.) and has internal threads for easy engagement with screws and bolts. It is typically made of high-strength, corrosion-resistant metal to withstand the heat and electrodynamic forces generated when high-voltage current passes through. The outer liner is made of plastic and can be integrally mounted with the base plate 1 or detachably connected to the base plate 1, for example, through snap-fit ​​connections, tongue-and-groove connections, bolt connections, etc.

[0033] According to some embodiments of this application, the clip 5, as a fixing element of the low-voltage wire harness 14, is designed in the second region A2 and the fourth region. Through its elastic design, the clip 5 achieves rapid clamping and fixing of the wire harness, greatly improving assembly efficiency. These clips 5 not only have sufficient strength to withstand the weight of the wire harness and external tension, but also achieve rapid fixing and release of the wire harness through their unique structural design. Specifically, the clips 5 are typically made of elastic materials, such as plastic or rubber. Clips 5 made of flexible materials effectively protect the wire harness while fixing it, preventing damage caused by friction or compression.

[0034] According to some embodiments of this application, the material of the buckle 5 can be polypropylene, silicone, etc.

[0035] According to some embodiments of this application, in a power battery system, the high-voltage busbar 13 typically carries a high voltage and current, while the low-voltage harness 14 is responsible for transmitting control signals and low-power electrical energy. In order to eliminate the interference of heat and electromagnetic fields generated by the high-voltage busbar 13 on the low-voltage harness 14, this application designs the first separator 2 and the second separator 3 as plates with excellent heat insulation and electromagnetic shielding properties.

[0036] According to some embodiments of this application, such as Figure 6 As shown, the first partition 2 and the second partition 3 are composite material structures, each comprising: a first wear-resistant layer 15, an electromagnetic shielding layer 16, a heat-insulating core layer 17, and a second wear-resistant layer 18. The first wear-resistant layer 15 is made of polycarbonate or polyamide. The electromagnetic shielding layer 16, located on the first wear-resistant layer 15, is a conductive plastic composite material layer, metal foil, or metallized fabric. The heat-insulating core layer 17, located on the side of the electromagnetic shielding layer 16 away from the first wear-resistant layer 15, is made of aerogel felt, closed-cell foam plastic, or vacuum insulation board. The second wear-resistant layer 18, located on the side of the heat-insulating core layer 17 away from the first wear-resistant layer 15, is also made of polycarbonate or polyamide.

[0037] According to some embodiments of this application, the first separator 2 and the second separator 3, as core components of the integrated power battery bracket, have a composite layer structure design that is of great significance for improving the overall performance and safety of the bracket. The composite layer structure design enables the first separator 2 and the second separator 3 to simultaneously possess multiple functions such as wear resistance, electromagnetic shielding, and heat insulation. This not only effectively protects the high-voltage busbar 13 and the low-voltage wiring harness 14 from interference and damage from the external environment, but also improves the overall safety and reliability of the battery module. Simultaneously, the composite layer structure design also helps to reduce the overall weight of the bracket and increase the energy density of the battery module.

[0038] Specifically, the first wear-resistant layer 15 and the second wear-resistant layer 18 mainly serve to protect and support, preventing the electromagnetic shielding layer 16 and the heat insulation core layer 17 from wear and damage during long-term use. The electromagnetic shielding layer 16, through materials such as conductive plastic composite material layers, metal foil, or metallized fabric, effectively blocks the interference of the electromagnetic field generated by the high-voltage busbar 13 on the low-voltage wiring harness 14, ensuring the acquisition accuracy of the low-voltage wiring harness 14 and the normal operation of the BMS system. The heat insulation core layer 17, using highly efficient heat insulation materials such as aerogel felt, closed-cell foam plastic, or vacuum insulation board, effectively blocks the transfer of heat generated by the high-voltage busbar 13 to the low-voltage wiring harness 14 area, preventing thermal runaway.

[0039] A suitable adhesive is needed to bond the electromagnetic shielding layer 16 to the wear-resistant layer to ensure a tight bond and prevent detachment. The thickness and material selection of the heat insulation core layer 17 need to be determined based on the specific application scenario and safety standards. The overall performance of the partition can be further optimized by adjusting the thickness and order of each layer. For example, increasing the thickness of the electromagnetic shielding layer 16 can improve its electromagnetic shielding effect; increasing the thickness of the heat insulation core layer 17 can improve its heat insulation performance. Optionally, the first partition 2 and the second partition 3 can also be configured as a double electromagnetic shielding layer 16, with the two electromagnetic shielding layers 16 symmetrically arranged on both sides of the heat insulation core layer 17 for better results.

[0040] According to some embodiments of this application, the integrated power battery bracket further includes a first enclosure plate 6, which is disposed within the first region A1 and the third region A3. The first enclosure plate 6 is connected to the first partition plate 2 and the second partition plate 3, and encloses the first region A1 and the third region A3 into a groove-shaped structure. The first enclosure plate 6 has a guide interface 7 parallel to the base plate 1, and the length and height of the guide interface 7 are adapted to the dimensions of the high-voltage busbar 13.

[0041] According to some embodiments of this application, to further enhance the installation stability and heat dissipation performance of the high-voltage busbar 13, a first enclosure plate 6 is added to the bracket. This first enclosure plate 6 is installed within the first region A1 and the third region A3, and is tightly connected to the first partition plate 2 and the second partition plate 3, forming a closed groove structure that effectively prevents the high-voltage busbar 13 from loosening or falling off under vibration or external impact. This groove structure not only provides a safe installation environment for the high-voltage busbar 13, but also, through the design of its guide interface 7, achieves precise positioning and rapid installation of the busbar. The length and height of the guide interface 7 are carefully calculated to ensure a perfect match with the dimensions of the high-voltage busbar 13, thereby avoiding poor contact or short circuit problems caused by improper installation.

[0042] During installation, the operator only needs to insert the front end of the high-voltage manifold 13 through the guide interface 7 to tighten the bolts and screws. The shape and size of the front end of the high-voltage manifold 13 are compatible with the first area A1, the third area A3, and the guide interface 7. When the front end of the high-voltage manifold 13 is fully inserted through the guide interface 7, the mounting hole 10 (or mounting notch) on the high-voltage manifold 13 is aligned with the threaded bushing 4. At this point, screwing in the bolts and screws will complete the fixation of both, improving assembly efficiency and accuracy.

[0043] According to some embodiments of this application, the integrated power battery bracket also includes a reinforcing rib 12, which is disposed in the first region A1 and the third region A3.

[0044] In this embodiment, optionally, the reinforcing rib 12 is typically made of the same material as the base plate 1 to ensure good mechanical properties and durability. Through reasonable layout and design, the reinforcing rib 12 can effectively disperse the stress generated by the support when subjected to external pressure or vibration, thereby preventing deformation or damage to the support. The presence of the reinforcing rib 12 significantly improves the overall rigidity of the support, enabling it to better withstand external pressure and vibration without deformation.

[0045] According to some embodiments of this application, there are multiple reinforcing ribs 12, which are spaced apart along a first direction or a second direction, and the multiple reinforcing ribs 12 intersect to form a mesh structure.

[0046] In this embodiment, to further optimize the mechanical properties of the support, this application adopts a design scheme in which multiple reinforcing ribs 12 are spaced apart along the first and second directions. These reinforcing ribs 12 form a grid-like structure inside the support, further enhancing the overall rigidity of the support.

[0047] According to some embodiments of this application, the integrated power battery bracket further includes a second enclosure plate 8, which is disposed within the second region A2 and the fourth region A4. The second enclosure plate 8 is connected to one of the first partition plate 2 and the second partition plate 3, and encloses the second region A2 and the fourth region A4 into a groove-shaped structure with a slot on one side. A wire hole 9 is provided on the side of the second enclosure plate 8 near the slot. The wire hole 9 is configured to allow a low-voltage wiring harness 14 to enter the second region A2 or the fourth region A4 and be engaged in a snap-fit ​​5.

[0048] In this embodiment, to further optimize the arrangement and protection of the low-voltage wiring harness 14, a second enclosure 8 is specially designed in the second region A2 and the fourth region of the bracket. This second enclosure 8 is tightly connected to either the first partition 2 or the second partition 3 (chosen according to the actual layout), forming a groove-like structure with slots on the side. This groove-like structure not only provides a safe arrangement environment for the low-voltage wiring harness 14, but also achieves precise guidance and fixation of the harness through the design of its wire hole 9. Specifically, the position and size of the wire hole 9 are carefully calculated to ensure that the low-voltage wiring harness 14 can smoothly enter the groove and be accurately fixed by the clip 5, thereby avoiding a chaotic arrangement of the harness and potential safety hazards.

[0049] The second enclosure 8, by forming a groove structure, provides a clear arrangement path for the low-voltage wiring harness 14, avoiding wiring confusion and crossing. The design of the wire hole 9 allows the low-voltage wiring harness 14 to enter the groove according to the preset path, improving assembly efficiency and accuracy. The cooperation between the clip 5 and the wire hole 9 ensures the low-voltage wiring harness 14 is firmly fixed in the groove, preventing the wiring harness from loosening or falling off due to vibration or external impact.

[0050] According to some embodiments of this application, the number of threaded bushings 4 is two, three or more.

[0051] In this embodiment, the threaded bushing 4, as a key component of the integrated power battery bracket, primarily functions to provide a stable mounting position for the high-voltage busbar 13. Increasing the number of threaded bushings 4 can distribute the fixing pressure of the high-voltage busbar 13 on the bracket, improving the overall structural stability. Simultaneously, the design of multiple threaded bushings 4 helps optimize current distribution and reduce safety hazards caused by localized overheating. When the battery module suffers external impact, multiple fixing points can also better absorb the impact force, protecting the internal structure of the battery from damage.

[0052] The high-voltage busbar 13 is tightly connected to the support base plate 1 via threaded bushings 4, forming a stable current transmission path. Each threaded bushing 4 is precisely designed to ensure sufficient and uniform contact with the high-voltage busbar 13, reducing resistance and heat generation. In practical applications, the number of threaded bushings 4 needs to be determined based on the specific size of the battery module, current requirements, and safety standards. For example, for large power battery modules, three or more threaded bushings 4 may be needed to ensure sufficient fixing force and current transmission capacity. Furthermore, the layout of the threaded bushings 4 also needs to consider the heat dissipation requirements of the battery module, avoiding concentrated placement in high-temperature areas to prevent localized overheating.

[0053] According to some embodiments of this application, the base plate 1 is further provided with mounting holes 10, which are located in the second region A2 and the fourth region A4. The mounting holes 10 are configured to cooperate with screws or bolts to mount the base plate 1 onto the integrated power battery.

[0054] In this embodiment, the mounting hole 10 allows the bracket to be securely fixed to the power battery, ensuring the stability and safety of the battery module under various operating conditions. The mounting hole 10 simplifies and speeds up the installation and removal of the bracket, improving production efficiency. Simultaneously, the tightening action of screws or bolts ensures close contact between the bracket and the power battery, reducing loosening or displacement caused by vibration or impact. Furthermore, the design of the mounting hole 10 considers the heat dissipation requirements of the battery module, avoiding its placement in high-temperature areas to prevent heat from being conducted to the outside of the bracket and affecting battery performance.

[0055] During installation, first place the bracket in the designated position on the power battery. Then, pass screws or bolts through the mounting holes 10 to the corresponding holes on the bracket and the power battery. Finally, use a tool to tighten the screws or bolts to ensure a tight connection between the bracket and the power battery. For disassembly, simply reverse the process to easily remove the bracket.

[0056] According to some embodiments of this application, a mis-installation notch 11 is provided on the base plate 1, and the mis-installation notch 11 is located in the second region A2 or the fourth region A4 (choose one).

[0057] In this embodiment, the anti-misinstallation notch 11 is a key aspect of the user-friendly design of the integrated power battery bracket. The anti-misinstallation notch 11 effectively prevents directional errors or positional shifts in the bracket during installation, improving installation efficiency and accuracy. The design of the anti-misinstallation notch 11 significantly reduces the error rate during installation, minimizing rework and repair costs caused by improper installation. Simultaneously, it enhances the overall safety and reliability of the battery module, preventing performance degradation or safety hazards due to bracket installation errors.

[0058] The anti-misinstallation notch 11 is typically located on the edge or at a specific position of the bracket base plate 1, and its shape and size match the corresponding protrusion or groove on the power battery. During installation, the operator only needs to align the anti-misinstallation notch 11 of the bracket with the protrusion or groove on the power battery to ensure the correct installation orientation and position of the bracket. This design makes the installation process more intuitive and simple, reducing operational difficulty and error rate. The shape, size, and position of the anti-misinstallation notch 11 need to be determined according to the specific design of the battery module.

[0059] According to some embodiments of this application, the base plate 1 is circular, elliptical, polygonal, or rounded rectangle in shape.

[0060] In this embodiment, the shape design of the base plate 1 is an important manifestation of the integrated power battery bracket's adaptability to the needs of different power battery modules. By selecting a suitable shape for the base plate 1, the bracket can better match the power battery module, improving the overall structural stability and safety. Different base plate 1 shapes have different advantages, disadvantages, and applicable scenarios. For example, a circular base plate has good symmetry and rotational stability, suitable for battery modules that require frequent rotation or orientation adjustments; an elliptical base plate can reduce weight while ensuring structural strength, suitable for weight-sensitive applications; a polygonal base plate can adapt to different spatial layouts and installation requirements by adjusting the number of sides and angles; a rounded rectangular base plate combines the advantages of rectangles and circles, possessing both good space utilization and a certain degree of rotational stability. The basic principles of this application have been described above with reference to specific embodiments. However, it should be noted that the advantages, benefits, and effects mentioned in this application are merely examples and not limitations, and should not be considered as essential features of each embodiment of this application. Furthermore, the specific details disclosed above are only for illustrative and facilitative purposes, not limitations, and do not restrict this application from being implemented using the specific details described above.
