Description

Technical Field

[0001] The utility model relates to the technical field of power supplies, in particular to a high-efficiency and energy-saving board-mounted power supply. Background Art

[0002] An onboard power supply is one that integrates the power supply circuitry onto the printed circuit board (PCB) or uses an onboard power module. This allows the power supply to be integrated onto the same board as the application circuitry. This allows the power supply to operate directly from the mains, without the need for external conversion or an external power adapter.

[0003] When the onboard power supply is in use, the high temperature of the onboard power supply will result in high energy consumption. Therefore, the onboard power supply will be cooled to reduce the energy consumption during operation and achieve the purpose of energy saving.

[0004] In actual use, an on-board power supply is usually fixed to a PCB circuit board to convert the current so that other electrical components on the PCB circuit board can directly use the mains power. However, the existing fixing method on the market usually directly solders the on-board power supply to the PCB circuit board. When the on-board power supply needs to be repaired in the future, the disassembly method is relatively cumbersome. At the same time, during installation, complex tools are also required to solder the on-board power supply body to the PCB circuit board, and the disassembly and assembly method is relatively cumbersome. In view of this, we propose a high-efficiency and energy-saving on-board power supply to solve the above problems. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present invention provides an efficient and energy-saving on-board power supply, which has the advantage of being easy to disassemble and repair, and solves the problem that the on-board power supply body is directly welded on the PCB circuit board, which is not conducive to later maintenance.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-efficiency and energy-saving on-board power supply, comprising an on-board power supply body and a PCB circuit board;

[0007] Two groups of conductive sheets, the two groups of conductive sheets are electrically connected to two ends of the board-mounted power supply body respectively;

[0008] Two fixing boxes, the two fixing boxes are respectively fixed at two ends of the board-mounted power supply body, and the fixing boxes are also provided with disassembly and assembly components;

[0009] The board-mounted power supply body is provided with a heat dissipation component;

[0010] The disassembly assembly comprises a threaded sleeve threadedly connected to the top surface of the fixed box, a rotating shaft is fixed inside the threaded sleeve, a knob is fixed on the top surface of the rotating shaft, and a top cone is fixed on the bottom surface of the rotating shaft;

[0011] The disassembly and assembly components also include movable plates that pass through the fixed boxes and are slidably connected thereto. The outer surfaces of the movable plates are fixed with retaining rings, and the opposite ends of the two retaining rings are fixed with springs. The outer surface of the fixed box is fixed with a positioning plate.

[0012] Furthermore, opposite ends of the two springs are fixed to two ends of the inner cavity of the fixed box respectively, and the two springs are sleeved with the movable plate.

[0013] Furthermore, one opposite end of the two movable plates is semi-annular, the top cone is conical, and both ends of the top cone are slidably connected to the two movable plates respectively.

[0014] Furthermore, a buffer pad is fixed to the bottom surface of the board-mounted power supply body, and the buffer pad is soft.

[0015] Furthermore, the heat dissipation component includes a plurality of heat dissipation fins fixed at two ends of the board-mounted power supply body and distributed at equal distances. The heat dissipation component also includes heat dissipation holes opened at the other two ends of the board-mounted power supply body.

[0016] Furthermore, two positioning holes are provided on the PCB circuit board, the two fixed boxes are respectively located inside the two positioning holes, the bottom surface of the positioning plate is in contact with the PCB circuit board, and the bottom surface of the movable plate is in contact with the PCB circuit board.

[0017] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0018] 1. When the on-board power supply of this high-efficiency and energy-saving board-mounted power supply needs to be fixed on the PCB circuit board, the bottom ends of the two fixing boxes are first inserted into the two positioning holes reserved on the PCB circuit board. When the bottom surfaces of the two positioning plates are in contact with the PCB circuit board, the two movable plates are extended by turning the knob, so that the top surfaces of the movable plates are in contact with the bottom surface of the PCB circuit board, thereby fixing the on-board power supply body to the PCB circuit board and avoiding the traditional method of installing it by welding, which is not conducive to the subsequent disassembly and maintenance of the on-board power supply body.

[0019] 2. This high-efficiency and energy-saving onboard power supply can dissipate the heat generated by the onboard power supply body during operation by fixing multiple heat dissipation fins at both ends of the onboard power supply body, and by providing heat dissipation holes at the other two ends of the onboard power supply body, air can be driven to flow into the onboard power supply body, further dissipating the hot air in the onboard power supply body. By driving the onboard power supply body to dissipate heat, the onboard power supply body can effectively achieve the purpose of energy saving. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation

[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts fall within the protection scope of the utility model.

[0027] Please refer to Figure 1 A kind of high-efficiency energy-saving on-board power supply in the embodiment, including on-board power supply body 1 and PCB circuit board 3, two positioning holes are set on PCB circuit board 3, buffer pad is fixed on the bottom surface of on-board power supply body 1, and buffer pad is soft;Two groups of conductive sheets 2, two groups of conductive sheets 2 are electrically connected at the two ends of on-board power supply body 1 respectively;Two fixed boxes 4, two fixed boxes 4 are located inside two positioning holes respectively, two fixed boxes 4 are fixed at the two ends of on-board power supply body 1 respectively, and dismounting assembly is further provided in fixed box 4;On-board power supply body 1 is provided with heat dissipation assembly.

[0028] Please refer to Figure 2 In order to drive on-board power supply body 1 to heat dissipation, so as to achieve the purpose of energy saving, the heat dissipation assembly in the embodiment includes multiple heat dissipation fins 5 equidistantly distributed fixed at the two ends of on-board power supply body 1, and the heat dissipation assembly further includes heat dissipation hole 6 set at the other two ends of on-board power supply body 1.

[0029] Therefore, by fixing a plurality of heat dissipation fins 5 at both ends of the on-board power supply body 1, the heat generated by the on-board power supply body 1 during operation can be dissipated, and by providing heat dissipation holes 6 at the other two ends of the on-board power supply body 1, air can be driven to flow into the on-board power supply body 1, and the hot air in the on-board power supply body 1 can be further discharged. By driving the on-board power supply body 1 to dissipate heat, the on-board power supply body can effectively achieve the purpose of energy saving.

[0030] See also Figure 4 、 Figure 5 In order to fix the onboard power supply body 1 and the PCB board, the disassembly and assembly components in this embodiment include a threaded sleeve 7 threadedly connected to the top surface of the fixing box 4, a rotating shaft 8 is fixed inside the threaded sleeve 7, a knob 9 is fixed to the top surface of the rotating shaft 8, and a top cone 10 is fixed to the bottom surface of the rotating shaft 8.

[0031] The disassembly and assembly components also include movable plates 11 that pass through the fixed box 4 and are slidably connected thereto. The bottom surface of the movable plate 11 fits against the PCB circuit board 3. The top cone 10 is conical, and the two ends of the top cone 10 are slidably connected to the two movable plates 11 respectively. The opposite ends of the two movable plates 11 are semi-annular. A retaining ring 12 is fixed to the outer surface of the movable plate 11. The two retaining rings 12 are fixed with springs 13 at the opposite ends. The opposite ends of the two springs 13 are respectively fixed to the two ends of the inner cavity of the fixed box 4, and the two springs 13 are socketed with the movable plate 11; a positioning plate 14 is fixed to the outer surface of the fixed box 4, and the bottom surface of the positioning plate 14 fits against the PCB circuit board 3.

[0032] When it is necessary to fix the on-board power supply body 1 on the PCB circuit board 3, first, the bottom ends of the two fixing boxes 4 are inserted into the two positioning holes reserved on the PCB circuit board 3. When the bottom surfaces of the two positioning plates are in contact with the PCB circuit board, the knob 9 is turned. When the knob 9 is turned, the knob 9 will drive the rotating shaft 8 fixed thereto to rotate. During the rotation of the rotating shaft 8, because the outer surface of the rotating shaft 8 is fixed with a threaded sleeve 7, when the knob 9 is rotated, the threaded sleeve 7 on the outer surface of the rotating shaft 8 is driven to rotate. The threaded sleeve 7 is threadedly connected to the fixing box 4. Therefore, during the rotation of the threaded sleeve 7, the rotating shaft 8 is driven to move downward. Further, when the rotating shaft 8 moves downward, the two ends of the top cone 10 are driven to push the two movable plates 11 respectively, so that the two movable plates 11 extend out of the fixing box 4, so that the top surface of the movable plate 11 is in contact with the bottom surface of the PCB circuit board 3, thereby achieving the fixation of the on-board power supply body 1 and the PCB circuit board 3, avoiding the traditional method of installing it by welding, which is not conducive to the subsequent disassembly and maintenance of the on-board power supply body 1.
