Description

Technical Field

[0001] This utility model relates to the field of power circuit boards, specifically a quick-install power circuit board. Background Technology

[0002] Power supply circuit boards are the core components in electronic devices that convert input electrical energy into stable DC or AC output. Their design must take into account efficiency, safety, and anti-interference capabilities. Based on their working principles, they can be divided into linear power supplies and switching power supplies.

[0003] Currently, power circuit boards are typically installed using bolts. However, this method presents a problem: the tightness of the bolts needs to be considered, and the large number of bolts involved reduces the ease of installation. Therefore, the inventor urgently needs to design a mounting mechanism that improves the installation of power circuit boards, replacing the traditional bolt installation method and enhancing the ease and efficiency of power circuit board installation. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a quick-install power circuit board to solve the technical problems of low efficiency and cumbersome operation of the traditional bolt installation method for power circuit boards.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-install power circuit board, comprising a substrate and a circuit board body, wherein a plurality of support mechanisms are supported and installed between the substrate and the circuit board body, the support mechanisms including support columns that can be adjusted longitudinally, and a locking mechanism is provided on the surface of the substrate and at the four corners of the circuit board body to limit the position of the circuit board body.

[0006] The engaging mechanism includes a fixing component, the surface of which has several slots. Fixing pieces are fixedly installed at the four corners of the circuit board body. The outer side of the fixing piece is engaged with the slots through a locking block.

[0007] By adopting the above technical solution, the support column of the support mechanism can be adjusted longitudinally, which can flexibly adapt to the circuit board body with different heat dissipation requirements, ensure the support stability between it and the substrate, and avoid circuit board deformation caused by installation errors.

[0008] Furthermore, several of the aforementioned support mechanisms are distributed at the corners of the circuit board body, and the support points of the circuit board body do not conflict with the positions of the components on the circuit board body.

[0009] By adopting the above technical solution, the support mechanism is distributed at the corners of the circuit board body. The mechanical stress is dispersed by multiple support points, avoiding excessive local stress that could cause the circuit board body to crack or components to be damaged.

[0010] Furthermore, a heat-conducting sheet is embedded and fixedly installed on the surface of the circuit board body at a position opposite to the support column, and the heat-conducting sheet abuts against the top of the support column.

[0011] By adopting the above technical solution, the heat-conducting sheet embedded in the main body of the circuit board directly contacts the top of the support column, forming an efficient heat conduction channel. The heat generated by the main body of the circuit board during operation can be quickly transferred to the substrate for diffusion, which improves the heat dissipation efficiency compared with the traditional air cooling solution.

[0012] Furthermore, the top of the support column is bonded to the heat-conducting sheet with thermal grease, and several heat dissipation fins are arranged in a ring at equal intervals on the outer surface of the support column.

[0013] By adopting the above technical solution, the top of the support column is bonded to the thermally conductive sheet with thermally conductive grease, which fills the micro gaps on the contact surface, significantly reduces thermal resistance, and ensures efficient heat transfer from the circuit board body to the substrate.

[0014] Furthermore, an adjusting screw is threadedly connected to the lower part of the support column, the adjusting screw is rotatably connected to the base plate, and an adjusting ring is fixedly provided on the adjusting screw.

[0015] By adopting the above technical solution and adjusting the threaded connection between the screw and the support column, the precise lifting and lowering of the support column can be achieved by rotating the adjusting ring, which solves the cumbersome problem of repeated disassembly and assembly required for traditional shim adjustment.

[0016] Furthermore, the fixing member is a right-angle bent member and covers the four corners of the circuit board body. Several of the slots are arranged linearly at equal intervals along the height line of the fixing member to adapt to the installation requirements of the spacing between the circuit board body and the substrate.

[0017] By adopting the above technical solution, the right-angle bending structure of the fastener covers the four corners of the circuit board body, and the three-dimensional positioning enhances the fixing stability, preventing the circuit board body from lateral displacement or warping in a vibration environment.

[0018] Furthermore, the locking block has a wedge-shaped structure, and the inner side of the top of the fixing member has an inclined surface, which serves as a guide inclined surface for the locking block.

[0019] By adopting the above technical solution, the wedge-shaped structure of the card block and the inner guide slope of the fixing component can make the circuit board body automatically slide into the card slot by one-way pressing during installation, without the need for manual alignment, which greatly reduces the assembly difficulty.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model replaces traditional bolt installation with a snap-fit ​​mechanism, improving installation efficiency. The wedge-shaped inclined surfaces of the fixing component and the snap-fit ​​block cooperate to achieve "press-snap" fixation of the circuit board body, eliminating the need for tools and reducing installation time. At the same time, the multi-level slots on the fixing component allow for flexible adjustment of the distance between the circuit board body and the substrate, adapting to different heat dissipation or mechanical strength requirements.

[0022] 2. This utility model uses the adjusting screw of the support mechanism to drive the support column to rise and fall, and forms an efficient heat dissipation channel through the heat-conducting plate and heat dissipation fins to reduce the temperature of the circuit board; the support point avoids the component layout of the main body of the circuit board to avoid mechanical interference, and the right-angle bent fastener covers the four corners of the circuit board to enhance the lateral limiting stability and prevent displacement in the vibration environment.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1:

[0030] A quick-release power circuit board, such as Figure 1-4 As shown, it includes a substrate 1 and a circuit board body 2. Several support mechanisms 3 are supported and installed between the substrate 1 and the circuit board body 2. The support mechanism 3 includes a support column 301 that can be adjusted in the longitudinal position. The surface of the substrate 1 and the four corners of the circuit board body 2 are provided with a locking mechanism 4 to restrict the position of the circuit board body 2.

[0031] The locking mechanism 4 includes a fixing member 401, the surface of which has several slots 402. Fixing pieces 403 are fixedly installed at the four corners of the circuit board body 2. The outer side of the fixing piece 403 is connected to the slots 402 by a locking block 404 through the fixing member 401. The support column 301 of the support mechanism 3 can be adjusted longitudinally to flexibly adapt to the circuit board body 2 with different heat dissipation requirements, ensuring the support stability between it and the substrate 1 and avoiding circuit board deformation due to installation errors. At the same time, the locking mechanism 4 uses the inclined surface of the fixing member 401 and the locking block 404 to quickly fix the circuit board body 2 through the mechanical action of "pressing and locking", which significantly reduces the installation time and does not require tool operation, making it especially suitable for scenarios that require frequent maintenance.

[0032] See Figure 1 , Figure 2 , Figure 3 Several support mechanisms 3 are distributed at the corners of the circuit board body 2, and the support points of the circuit board body 2 do not conflict with the positions of the components on the circuit board body 2. The support mechanisms 3 are distributed at the corners of the circuit board body 2, and the mechanical stress is dispersed by supporting multiple points, so as to avoid the circuit board body 2 cracking or components being damaged due to excessive local stress. At the same time, the support points avoid the layout of components on the circuit board body 2, which solves the problem of installation failure caused by spatial conflicts in traditional support structures.

[0033] See Figure 1 , Figure 2 , Figure 3 A heat-conducting plate 302 is embedded and fixedly installed on the surface of the circuit board body 2, opposite to the position of the support column 301. The heat-conducting plate 302 abuts against the top of the support column 301. The heat-conducting plate 302 embedded in the circuit board body 2 directly abuts against the top of the support column 301, forming an efficient heat conduction channel. The heat generated by the circuit board body 2 during operation can be quickly transferred to the substrate 1 for diffusion. Compared with the traditional air cooling solution, the heat dissipation efficiency is improved. At the same time, the heat-conducting plate 302 is embedded in the surface of the circuit board body 2, without occupying extra space, avoiding assembly interference problems caused by external heat sinks.

[0034] See Figure 1 , Figure 2 , Figure 3 The top of the support column 301 is bonded to the heat-conducting sheet 302 with thermal grease. Several heat dissipation fins 305 are arranged in an equidistant ring on the outer surface of the support column 301. The top of the support column 301 is bonded to the heat-conducting sheet 302 with thermal grease, which fills the micro gaps on the contact surface, significantly reduces thermal resistance, and ensures efficient heat transfer from the circuit board body 2 to the substrate 1. At the same time, the annular heat dissipation fins 305 on the outer surface of the support column 301 accelerate air convection heat dissipation by increasing the surface area, forming a dual heat dissipation mechanism of "conduction-convection", which can effectively control the temperature rise of the circuit board even under high load conditions.

[0035] Example 2:

[0036] See Figure 1 , Figure 2 , Figure 3 An adjusting screw 303 is threadedly connected to the lower part of the support column 301. The adjusting screw 303 is rotatably connected to the base plate 1. An adjusting ring 304 is fixedly installed on the adjusting screw 303. The threaded connection between the adjusting screw 303 and the support column 301 allows for precise raising and lowering of the support column 301 by rotating the adjusting ring 304. This solves the cumbersome problem of repeated disassembly and assembly required for traditional shim adjustment. At the same time, the rotatable connection structure between the adjusting screw 303 and the base plate 1 ensures the stability of the adjustment process and avoids displacement of the circuit board body 2 caused by manual operation.

[0037] See Figure 1 , Figure 2 , Figure 3 The fastener 401 is a right-angle bent component that covers the four corners of the circuit board body 2. Several slots 402 are arranged linearly at equal intervals along the height line of the fastener 401 to accommodate the installation requirements of the distance between the circuit board body 2 and the substrate 1. The right-angle bent structure of the fastener 401 covers the four corners of the circuit board body 2, and enhances the fixing stability through three-dimensional limiting, preventing the circuit board body 2 from lateral displacement or warping in a vibration environment. At the same time, the slots 402 arranged linearly at equal intervals on the fastener 401 provide multi-level height adjustment function, allowing users to select the locking position according to actual needs, which significantly expands the application range of this structure.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The locking block 404 has a wedge-shaped structure, and the inner side of the top of the fixing member 401 has an inclined surface, which serves as the guide inclined surface for the locking block 404. The wedge-shaped structure of the locking block 404 and the inner guide inclined surface of the fixing member 401 cooperate to allow the circuit board body 2 to automatically slide into the slot 402 by one-way pressing during installation, without the need for manual alignment, which greatly reduces the assembly difficulty. At the same time, the inclined contact setting of the wedge-shaped structure reduces the frictional resistance during the locking process, avoids wear of the fixing piece 403 or the slot 402 due to repeated disassembly and assembly, and extends the service life of the mechanism.

[0039] The implementation principle of this embodiment is as follows:

[0040] Installation stage: The circuit board body 2 is placed on the substrate 1, and the fixing pieces 403 at its four corners are embedded in the slots 402 of the fixing piece 401 through the wedge-shaped blocks 404. The inclined surface of the blocks 404 cooperates with the inner guide inclined surface of the fixing piece 401 to achieve quick positioning by "pressing and sliding in", replacing the traditional bolt fastening.

[0041] Adjustment and fixing: The support column 301 is driven to rise and fall by rotating the adjustment screw 303, so that the top of the support column 301 is in close contact with the heat-conducting plate 302 at the bottom of the circuit board body 2 to form a stable support. At the same time, the support point avoids the components on the circuit board body 2. The heat dissipation fins 305 distributed in a ring on the surface of the support column 301 are combined with thermal grease to efficiently conduct the heat of the circuit board body 2 to the substrate 1 and the heat dissipation fins 305.

[0042] Adaptability design: The multi-level slots 402 on the fastener 401 allow for flexible adjustment of the distance between the circuit board body 2 and the substrate 1 to meet different heat dissipation or mechanical strength requirements.
