Description
Technical Field
[0001] The present invention relates to the technical field of power supply equipment, and in particular to a multi-output port power supply equipment capable of adjusting output power. Background Art
[0002] A multi-port power supply (MPS) is a device that can provide power to multiple electronic devices. It typically has multiple power connectors, allowing it to simultaneously charge or power multiple devices. By independently powering each device, a failure in one power path will not affect the normal operation of other devices, thereby improving the reliability and stability of the entire system. A mobile power supply device disclosed in the authorization announcement number CN 210510772 U relates to the field of power supply technology. The mobile power supply device includes a power module, a winch, and a housing. The power module includes a battery and a voltage conversion unit. The battery, voltage conversion unit, and winch are all fixedly arranged in the housing. The winch is used to store cables. The voltage conversion unit is connected to the load via cables. The housing is also provided with movable parts so that the mobile power supply device can be moved to supply power to the load, thereby making the mobile power supply device more convenient and flexible to use. In addition, the battery, voltage conversion unit, and winch are all fixedly arranged in the housing, so that the various components of the mobile power supply device are centralized and easy to manage.
[0003] In the process of using an existing multi-output port power supply device, the multi-output port power supply device usually connects the mains current supply connector to the inside, then connects the external connectors to the corresponding power supply connectors, and finally the current is passed through the power supply connector to the external electrical components, thereby realizing the power supply operation of the multi-output port power supply device. During the power supply operation of the multi-output port power supply device, a fan is used to reduce the temperature inside the multi-output port power supply device to prevent the temperature inside the multi-output port power supply device from being too high and affecting the normal operation of the device; Existing multi-output port power supply equipment generally does not have the function of adjusting the output power during operation. If it is necessary to connect electrical components of different specifications, it is often necessary to adjust it through an external transformer or power regulator to meet subsequent use. There are certain usage restrictions. Even if there are a small number of multi-output port power supply equipment with adjustable output power, the heat generated during the adjustment work is relatively large. Although the heat can be dissipated and cooled by the fan later, the position of the fan is fixed, resulting in a limited coverage area of the fan, so the heat dissipation effect is relatively poor. Some multi-output port power supply equipment with adjustable output power adjusts the position of the fan at the same time through multiple sets of drive devices. Although this method increases the coverage area of the fan, it also makes the internal structure of the multi-output port power supply equipment with adjustable output power more complicated and the cost is relatively high. For this reason, we propose a multi-output port power supply equipment with adjustable output power. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following advantages: 1. During the power supply operation of the multi-output port power supply device with adjustable output power, the fan starts to run through the control of the single-chip microcomputer. When the fan is running, suction is generated to discharge the hot air inside the cabinet through the vents. At this time, negative pressure is formed inside the cabinet, and the fresh air outside is filtered through the filter and finally enters the interior of the cabinet through the air inlet, thereby achieving the effect of cooling and heat dissipation. During the operation of the fan, the servo motor starts to run through the control of the single-chip microcomputer, and the output shaft of the servo motor drives the two-thirds gear to rotate.

By adjusting the position of the fan, the fan coverage area is increased, and the cooling and heat dissipation effect is further improved. Through the coordination of the two-thirds gear and the gear, the push plate can be driven to rotate, thereby adjusting the position of the fan, thereby increasing the fan coverage area, and further improving the cooling and heat dissipation effect. The whole process can be completed with only one motor, and the cost is relatively low.
[0015] 2. When the output power of the multi-port power supply device with adjustable output power needs to be adjusted, the adjustment motor starts running through the control of the single-chip microcomputer. The output shaft of the adjustment motor drives the bidirectional screw to rotate, and the bidirectional screw drives the two adjustment seats to move toward the end near the center of the cabinet. At this time, the distance between the two adjustment seats gradually decreases, thereby reducing the distance between the two transmission rods. As the distance decreases, the transmission rods exert an upward thrust on the fixing plate through the connecting seat, causing the fixing plate to drive the conductive post upward through the mounting seat, thereby changing the contact point between the conductive post and the resistance coil, thereby increasing the resistance value in the power supply line, thereby adjusting the output power of the multi-port power supply device with adjustable output power. By coordinating the adjustment seat and the connecting seat, the contact point between the conductive post and the resistance coil can be adjusted according to actual conditions, thereby adjusting the output power of the multi-port power supply device with adjustable output power. This simple operation replaces the traditional method of adjusting the output power of the multi-port power supply device with adjustable output power through an external transformer or power regulator.

During operation, the mains power is supplied through the conductive column 76 through the regulation of the single-chip microcomputer 3. Thereafter, the mains power passes through the conductive column 76, the resistance coil 79 and the voltage detector 11 in sequence, and finally the current is passed into the external electrical components through the power supply connector 5, thereby realizing the power supply work of the multi-output port power supply device with adjustable output power, and the conductive column 76 is always in contact with the resistance coil 79 under the influence of the elastic potential energy of the reset spring 77, ensuring that the electrical circuit is normally conductive to avoid interruption of the power supply work, and the voltage monitor 11 detects the voltage of the power supply circuit in real time.

At this time, the distance between the two adjustment seats 12 gradually decreases, thereby reducing the distance between the two transmission rods 15. Because the distance is reduced, the transmission rod 15 will give an upward thrust to the fixed plate 79 through the connecting seat 14, so that the fixed plate 79 drives the conductive column 76 to move upward through the mounting seat 74, thereby changing the connection between the conductive column 76 and the resistance coil 79. The contact position increases the resistance value in the power supply circuit, thereby adjusting the output power of the multi-output port power supply device with adjustable output power. During the power supply operation of the multi-output port power supply device with adjustable output power, the fan 63 starts to run through the regulation of the single-chip microcomputer 3. When the fan 63 runs, suction is generated to discharge the hot air inside the cabinet 1 through the vent 68.

During the operation of the fan 63, the servo motor 9 starts to run through the regulation of the single-chip microcomputer 3. The output shaft of the servo motor 9 drives the two-thirds gear 10 to rotate. When the two-thirds gear 10 is meshed with the gear 18 on the left, the gear 18 on the left drives the gear 18 on the right to rotate through the meshing connection, and then the gear 18 drives the push plate 65 to rotate upward through the mounting rod 64, the torsion spring 67 is twisted, and the push plate 65 drives the fan 63 to move upward through the mounting plate 62, and the spring 66 extends. When the two-thirds gear 10 is separated from the left gear 18, the torsion spring 67 rotates and resets to generate a torque that drives the push plate 65 to rotate downward and reset through the mounting rod 64, and the tension generated by the contraction of the spring 66 drives the fan 63 to move downward and reset through the mounting plate 62. By adjusting the position of the fan 63, the coverage area of the fan 63 is increased, and the cooling and heat dissipation effect is further improved.
