Description

Technical Field

[0001] This utility model relates to the field of power supply technology, specifically a three-dimensional power supply device with a circuit layer. Background Technology

[0002] Currently, the common structure of traditional power supply devices involves soldering electronic components onto a PCB substrate, followed by adding a metal or plastic casing for insulation and connecting other mounting devices. However, this design has several drawbacks. If a plastic casing is used, the heat generated by the electronic components is difficult to dissipate due to the insulating properties of plastic, resulting in poor heat dissipation and affecting power supply performance and stability. If a metal casing is used, an insulating layer must be added between the PCB and the metal casing to prevent short circuits, and the electronic components must have ample space or be wrapped with insulating sheets before assembly. This not only increases assembly difficulty and cost but also prevents heat from being effectively conducted away through the metal casing, again causing poor heat dissipation. Furthermore, existing power supply devices rely on additional casings for insulation protection, further increasing the complexity and cost of the device.

[0003] In the field of optoelectronic modules, existing linear optoelectronic modules and optical modules typically mount electronic components and LEDs onto an aluminum substrate, then use a transparent plastic shell for insulation and protection. However, the material properties of the aluminum substrate limit its bending ability, allowing only planar mounting and fixing. Furthermore, during installation, the electronic components are exposed on the surface of the aluminum substrate and cannot be hidden inside. This limits the application scenarios and design flexibility of optoelectronic modules to some extent, failing to meet diverse market demands. Therefore, a three-dimensional power supply device with a circuit layer is proposed to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a three-dimensional power supply device with a circuit layer, which has the advantages of improving the performance of the power supply device, simplifying the assembly process, enhancing protection capabilities, and expanding the application range. It solves the problems of heat dissipation difficulties, complex assembly structure, single insulation protection method, and limited installation of optoelectronic modules in existing power supply devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional power supply device with a circuit layer, comprising a flexible metal-based copper-clad laminate, mounting holes, a fire-retardant silicone coating, and electronic components. The flexible metal-based copper-clad laminate has mounting holes, and electronic components are welded into the cavity of the flexible metal-based copper-clad laminate. The electronic components are coated with a fire-retardant silicone coating. A fixing structure is provided on the flexible metal-based copper-clad laminate. An electronic component patch area is provided within the cavity of the flexible metal-based copper-clad laminate. A wire connected to a load is inserted into the mounting hole, and the wire is connected to the three-dimensional power supply device. A hexagonal nut is threaded onto the flexible metal-based copper-clad laminate, and a threaded rod is externally connected to the hexagonal nut, with a mechanical component externally connected to the threaded rod.

[0006] Furthermore, the substrate of the flexible metal-based copper-clad laminate is one or more of copper, iron, and aluminum, and the electronic components are encapsulated in the internal cavity.

[0007] Furthermore, the material of the fire-retardant silicone coating is one or more of acrylic resin, polyurethane resin, silicone resin, epoxy resin, and parylene.

[0008] Furthermore, the electronic components include isolation circuits, non-isolation circuits, linear drive circuits, and other control circuits, and the flexible metal-based copper-clad laminate is trimmed according to the design dimensions using a cutting device.

[0009] Furthermore, the mounting holes are divided into fixing holes and cable outlet holes. The hexagonal nut is used to thread the flexible metal-based copper-clad laminate onto the fixed structure through the fixing holes, and the wires are connected through the cable outlet holes for assembly with other electrical systems.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] 1. This utility model directly attaches electronic components to the surface of a flexible metal-based copper-clad laminate. The heat generated during operation can be quickly dissipated through the flexible metal-based copper-clad laminate, which greatly improves the heat conduction capacity of the internal electronic components. This significantly improves the working efficiency of the entire power circuit and increases the driving power within the same area, thereby achieving energy saving.

[0012] 2. The assembly structure of this utility model is simple, reducing the number of materials and parts used, and simplifying the assembly process. This not only reduces production costs, but also reduces the size of the power supply device, meeting the requirements of environmental protection and compact design.

[0013] 3. According to design requirements, this utility model can surface-mount different types of electronic devices, such as isolated circuits, non-isolated circuits and linear drive circuits, onto a flexible metal-based copper-clad laminate. Furthermore, the wiring on the flexible metal-based copper-clad laminate can be distributed in multiple directions after mechanical processing, which helps to further reduce the size of electronic devices, improve space utilization, and meet the usage needs of different scenarios.

[0014] 4. This utility model has good fireproof, waterproof, corrosion-proof and insulation protection properties. It is a protective, corrosion-resistant and fluid-resistant power drive or electronic control device that can operate stably in a variety of complex environments.

[0015] 5. This utility model has strong application flexibility. If a power cord is added, it can be used as an independent portable power supply device. If electronic wires are added and the base material is painted, it can also be used as a power supply device for decorative hardware parts that cover junction boxes, thus expanding its application field.

[0035] Step 1: Select Flexible Metal-Based Copper Clad Laminate 1

[0036] Based on specific heat dissipation requirements, the substrate of the flexible metal-based copper clad laminate 1 should be selected appropriately. The commonly used substrate is aluminum. In scenarios with high heat dissipation requirements, aluminum or copper-based copper clad laminates with excellent thermal conductivity should be given priority.
