[0019] To further illustrate the technical means and effects adopted by the utility model in order to achieve the intended purpose of the utility model, the following detailed description of the specific implementation methods, structure, features and effects of the utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0020] Please see Figures 1-4 As shown, the purpose of this embodiment is to provide a multi-port power output control board, including a circuit board 1, a power conversion module 2 fixedly disposed on one right end of the outer surface of the circuit board 1, a control module 3 fixedly disposed on the other right end of the outer surface of the circuit board 1, a plurality of small circuit components 4 fixedly disposed on the upper part of the outer surface of the circuit board 1, an input / output component 5 fixedly disposed on the upper left end of the outer surface of the circuit board 1, and a plurality of heat dissipation components 6 disposed on the upper end of the power conversion module 2.
[0021] The power conversion module 2 includes a transformer, rectifier, voltage regulator, iron core, diode, and transistor. The transformer is fixedly mounted on the circuit board 1, and the iron core is fixedly mounted on the transformer. The transformer is based on the principle of electromagnetic induction and converts the input voltage into the required output voltage through the coupling between the primary coil and the secondary coil. The iron core, as the magnetic circuit part of the transformer, can enhance the coupling between the coils and improve the conversion efficiency; at the same time, it also plays the role of supporting the coils and fixing the structure.
[0022] The rectifier is fixedly mounted on circuit board 1, the diode and transistor are fixedly mounted on the transformer, and the voltage regulator is fixedly mounted on circuit board 1. The rectifier uses the unidirectional conductivity of semiconductor materials to convert the positive and negative half-cycles of alternating current into positive voltage and zero voltage, respectively, thus obtaining pulsating direct current. The diode is the most basic rectifier element, while the transistor can adjust the collector current by controlling its base current to achieve more complex rectification functions. In the rectifier, the diode plays the role of unidirectional conductivity, enabling alternating current to be converted into direct current in a predetermined direction. At the same time, they also have certain voltage and current withstand capabilities, which can protect the subsequent circuits from overvoltage or current surges. The voltage regulator can automatically adjust the output voltage when the input voltage fluctuates or the load changes, keeping it within the set range.
[0023] The small circuit element 4 includes a relay, a sensor, a fuse, and a thermistor. The circuit board 1 is equipped with a protection circuit that can automatically detect abnormalities in the circuit and take corresponding measures to ensure the safety and reliability of the equipment and system.
[0024] The input / output component 5 includes two USB interfaces 51, two DP interfaces 52 and a 3.5mm audio interface 53. The USB interfaces 51 are fixedly mounted on the circuit board 1 and are used to connect to external devices or circuits.
[0025] The DP interface 52 is fixedly mounted on the circuit board 1. The DP interface 52 is used to connect to external devices or circuits.
[0026] A 3.5mm audio interface 53 is fixedly mounted on the circuit board 1, and a DP interface 52 is used for connection to external devices or circuits.
[0027] The heat dissipation assembly 6 includes at least a number of vertical heat-conducting plates 63 and horizontal heat-conducting plates 64. The horizontal heat-conducting plates 64 are fixedly connected to the vertical heat-conducting plates 63. The horizontal heat-conducting plates 64 have a number of heat dissipation holes 65. Two thermally conductive adhesive pillars 61 are provided on both sides of the vertical heat-conducting plates 63. The bottom of the thermally conductive adhesive pillars 61 is fixedly mounted on the circuit board 1. Connecting rods 62 are fixedly connected to both ends of the vertical heat-conducting plates 63. The thermally conductive adhesive pillars 61 are provided with grooves 68. A rotating shaft 67 is rotatably mounted on the groove 68 on one side of the thermally conductive adhesive pillar 61. An inclined surface 69 is provided on the groove 68 on the other side of the thermally conductive adhesive pillar 61. One end of the connecting rod 62 is fixedly connected to the rotating shaft 67, and the other end of the connecting rod 62 is engaged in the groove 68. Connecting posts 66 are fixedly connected between the connecting rods 62. The connecting posts 66 integrate all the connecting rods 62 into one unit so that they can rotate synchronously.
[0028] Rotating shaft 67 rotates downward, causing connecting rod 62 to rotate downward, causing heat-conducting horizontal plate 64 and heat-conducting vertical plate 63 to rotate downward. When heat-conducting horizontal plate 64 contacts power conversion module 2, connecting rod 62 at the other end is engaged in the groove 68 through inclined surface 69.
[0029] It should be noted that the inner wall of the bottom of the groove 68 into which the connecting rod 62 is engaged has several small particles to increase friction and fix the connecting rod 62 in the groove 68.
[0030] In practical use, when the power supply is turned on, the transformer in the power conversion module 2 converts the input voltage into the required output voltage through the coupling between the primary and secondary coils. The iron core, as the magnetic circuit part of the transformer, enhances the coupling between the coils and improves the conversion efficiency; it also supports the coils and fixes the structure. The rectifier utilizes the unidirectional conductivity of semiconductor materials to convert the positive and negative half-cycles of alternating current into positive and zero voltage, respectively, thus obtaining pulsating direct current. Diodes are the most basic rectifier elements, while transistors can adjust the collector current by controlling their base current to achieve more complex rectification functions, enabling alternating current to be converted into direct current in a predetermined direction. It also has certain voltage and current withstand capabilities, protecting subsequent circuits from overvoltage or current surges. The voltage regulator can automatically adjust the output voltage when the input voltage fluctuates or the load changes. The size is kept within a set range. The circuit board 1 is equipped with a protection circuit that can automatically detect abnormalities in the circuit and take corresponding measures to ensure the safety and reliability of the equipment and system. The USB interface 51, DP interface 52 and 3.5mm audio interface 53 in the input / output component 5 are used to connect with external devices or circuits. The rotating shaft 67 rotates downward, driving the connecting rod 62 to rotate downward, so that the heat-conducting horizontal plate 64 and the heat-conducting vertical plate 63 rotate downward. When the heat-conducting horizontal plate 64 contacts the power conversion module 2, the connecting rod 62 at the other end is engaged in the slot 68 through the inclined surface 69. Part of the heat is discharged through the heat dissipation holes 65 on the heat-conducting horizontal plate 64 covering the power conversion module 2, and the other part of the heat is transferred to the heat dissipation vertical plate 63 for discharge. The heat dissipation component 6 on the power conversion module 2 can be flipped to clean the dust from the power conversion module 2.
