Description

Technical Field

[0001] The present invention belongs to the technical field of direct current power supplies, and in particular relates to a multi-channel programmable direct current power supply device. Background Art

[0002] In many fields such as electronic equipment testing, industrial automation control, scientific research experiments, etc., DC power supply is the core power supply equipment, and its performance stability and reliability are of vital importance. Multi-channel programmable DC power supply device has the characteristics of being able to provide multiple independent and adjustable DC output channels at the same time, and the voltage, current and other parameters of each channel can be precisely controlled through programming, meeting the diverse power supply needs in complex systems. It plays an increasingly important role in the application of modern electronic technology. For example, in the integrated circuit testing scenario, different functional modules need to be provided with DC power supplies of different specifications. The multi-channel programmable characteristics enable a single power supply device to achieve coordinated power supply and precise control of multiple modules, greatly improving test efficiency and accuracy.

[0003] However, existing multi-channel programmable DC power supply devices still have some problems that need to be solved in practical applications. On the one hand, since the internal components of the power supply generate a lot of heat during operation, if the heat dissipation effect is not good, a long-term high-temperature environment will accelerate the aging of the components, resulting in a shortened service life of the power supply and internal components. It may also cause problems such as output parameter fluctuations, affecting the stability and reliability of the power supply. On the other hand, when the DC power supply fails and needs to be replaced, traditional devices often require the use of professional tools to disconnect the complex connection structure. The replacement process is tedious and time-consuming, seriously affecting the efficiency of equipment maintenance. In addition, in scenarios where multiple DC power supplies need to work together, there is a lack of a convenient assembly structure, making it difficult to quickly adapt to the needs of multiple DC power supplies being used together. This not only increases the difficulty of installation, but also is not conducive to the rational use of space. In view of this, we propose a multi-channel programmable DC power supply device.

Within the rectangular slot 26, from left to right, are located a filter plate 2 30, a plurality of motors 29, a mounting bracket 27, a plurality of fan blades 28, and a protective net 31. A protective shell 17 is provided on one side of the rectangular block 25. Three filter plates 18 are fixedly mounted on the periphery of the protective shell 17.

[0052] A limiting component is located inside the base 1 and is used to limit the protective shell 17;

[0053] A fixing groove 34 is provided on one side of the base 1, and two L-shaped plates 37 are provided on the other side of the base 1;

The rotation of the plurality of fan blades 28 can draw outside air into the rectangular slot 26 through the second filter plate 30. The air drawn in by the plurality of fan blades 28 then passes through the protective net 31 and blows toward the DC power supply 4, while the hot air in the protective shell 17 is discharged to the outside through the three first filter plates 18. This can accelerate the air circulation in the protective shell 17, ensure that the heat generated by the DC power supply 4 can be taken out to the outside, ensure that the DC power supply 4 can be dissipated, thereby extending the service life of the power supply and internal components, and ensuring the stability and reliability of the power supply operation.

[0056] At the same time, the protective shell 17 can protect the DC power supply 4, ensuring that the DC power supply 4 will not be damaged due to external impact, thereby extending the service life of the DC power supply 4;

[0057] When the DC power supply 4 is damaged, the personnel can release the limit of the protective shell 17 through the limiting component, and the personnel can move the protective shell 17 and remove the protective shell 17. Then, the personnel can release the fixing of the mounting plate 3 through the fixing component, and the personnel can pull the DC power supply 4 and the mounting plate 3 out of the mounting slot 2. At this time, the DC power supply 4 can be replaced, and then the replaced DC power supply 4 is placed between the four limiting plates 7. The four limiting plates 7 can ensure the stability of the DC power supply 4. When the mounting plate 3 is fully inserted into the mounting slot 2, the fixing component can fix the mounting plate 3, ensuring that when the DC power supply 4 is damaged, it is convenient for personnel to replace the DC power supply 4, and the replacement method is simple and fast without the need for other replacement tools;

[0058] When multiple sets of DC power supplies 4 are needed, personnel can insert the two L-shaped plates 37 on one base 1 into the fixing grooves 34 on the other base 1, and then drive the two L-shaped plates 37 away from each other through the driving component until one end of the two L-shaped plates 37 is inserted into the fixing grooves 34. At this time, the two fixing grooves 34 can limit the two bases 1, thereby fixing the two bases 1 together. Personnel can assemble multiple bases 1 together through the above operations to meet the needs of using multiple DC power supplies 4 together, and the assembly method is simple and quick, ensuring that personnel can easily assemble multiple DC power supplies 4 quickly.

[0062] Among them, personnel can press two pressing plates 14, and the two pressing plates 14 will respectively drive the two sliding blocks 10 to move, so that the two sliding blocks 10 move away from each other. The movement of the sliding blocks 10 will squeeze the springs 13 to shrink until one end of the sliding block 10 moves out of the corresponding limit groove 11. At this time, the two sliding blocks 10 can release the mounting plate 3, and personnel can pull the DC power supply 4 and the mounting plate 3 out of the mounting groove 2. At this time, the DC power supply 4 can be replaced, and then the replaced DC power supply 4 can be placed between the four limit plates 7.

[0091] In addition to realizing multi-base assembly, the drive assembly can also use the L-shaped plate 37 as a retractable fixed bracket through precise adjustment of the bidirectional threaded rod 38. When a single base 1 needs to be fixed on a workbench or cabinet, the L-shaped plate 37 can be extended and inserted into the preset fixing hole, and the knob 39 is tightened to achieve a rigid connection between the base and the support surface; at the same time, when the equipment is transported, the L-shaped plate 37 can be adjusted in reverse to clamp the two sides of the base, and cooperate with the internal shock-absorbing structure to form double protection, preventing components from loosening due to vibration during transportation, thereby improving the reliability of the equipment in mobile scenarios.

[0092] When the fixed component, the rectangular block 25, the limit component and the driving component work together, a modular heat dissipation network with dynamic reconstruction capability can be constructed. The DC power supply module 4 can be quickly disassembled and assembled through the sliding groove 9, the sliding block 10, the round rod 12, the spring 13 and the pressing plate 14 of the fixed component. In conjunction with the moving groove 35, the moving block 36, the L-shaped plate 37, the bidirectional threaded rod 38, the knob 39 and the rotating rod 40 of the driving component, the L-shaped plates 37 of multiple bases 1 are plugged into the fixed groove 34 to form a matrix structure. At this time, the rectangular groove 26, the mounting frame 27, the fan blades 28, the motor 29, the filter plate 2 30 and the protective net 31 in the rectangular block 25 form a through structure under the drive of the motor 29. The three-dimensional air duct passes through each protective shell 17, and the side wall filter plate 18 of the protective shell 17 locked by the slot 15, block 16, slide 19, limit block 20, round rod 21, spring 22, limit hole 23, pressing plate 24, groove 32 and protrusion 33 of the limit assembly and the filter plate 2 30 of the rectangular block 25 constitute an airflow channel node. The driving assembly can be adjusted by the knob 39 to change the spacing of the base 1 according to the distribution of the heat source, and the direction of the air duct can be dynamically optimized, so that the entire device can be used as a multi-channel power supply while also being transformed into an industrial-grade heat dissipation array with adaptive layout, providing auxiliary heat dissipation for other surrounding heating equipment, and realizing dual functional reuse of power supply and heat dissipation.

[0093] Working principle: When in use, personnel can start a number of motors 29, and the output shafts of the motors 29 will respectively drive the fan blades 28 to rotate. The rotation of the fan blades 28 can draw the outside air into the rectangular slot 26 through the filter plate 2 30. Then, the air drawn in by the fan blades 28 passes through the protective net 31 and blows toward the DC power supply 4, while the hot air in the protective shell 17 is discharged to the outside through the three filter plates 1 18, which can speed up the air circulation in the protective shell 17, ensure that the heat generated by the DC power supply 4 can be taken out to the outside, ensure that the DC power supply 4 can be cooled, thereby extending the service life of the power supply and internal components, and ensuring the stability and reliability of the power supply operation;

[0094] At the same time, the protective shell 17 can protect the DC power supply 4, ensuring that the DC power supply 4 will not be damaged due to external impact, thereby extending the service life of the DC power supply 4;

[0095] When the DC power supply 4 is damaged, personnel can press the pressing plate 24 downward. The downward movement of the pressing plate 24 will drive the limit block 20 to move downward. The downward movement of the limit block 20 will squeeze the two springs 22 to shrink until the top of the limit block 20 moves out of the limit hole 23. At this time, the limit block 20 can release the limit of the protective shell 17, and personnel can move the protective shell 17. The movement of the protective shell 17 will drive the two card blocks 16 and the protrusion 33 to move until the two card blocks 16 move out of the two card slots 15, and the protrusion 33 moves out of the groove 32. At this time, the protective shell 17 can be removed. Then, personnel can press the two pressing plates 14. The two pressing plates 14 will respectively drive the two sliding blocks 10 to move, so that the two sliding blocks 10 move away from each other. The movement of the sliding block 10 will squeeze several springs 13 to shrink until one end of the sliding block 10 is out of the corresponding limit slot 11 When the cam 11 is in the closed position, the two springs 13 are engaged, and the two springs 13 are engaged to retract the cam 11. When the cam 11 is in the closed position, the two springs 13 are engaged to retract the cam 11. When the cam 11 is in the closed position, the two springs 13 are engaged to retract the cam 11. When the cam 11 is in the closed position, the two springs 13 are engaged to retract the cam 11. When the cam 11 is in the closed position, the two springs 13 are engaged to retract the cam 11.

[0096] When multiple sets of DC power supplies 4 are needed, personnel can insert the two L-shaped plates 37 on one base 1 into the fixed slots 34 on the other base 1, and then turn the knob 39. The rotation of the knob 39 will drive the rotating rod 40 to rotate, and the rotation of the rotating rod 40 will drive the bidirectional threaded rod 38 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 38 will drive the two moving blocks 36 to move away from each other, and the two moving blocks 36 moving away from each other will drive the two L-shaped plates 37 to move away from each other until one end of the two L-shaped plates 37 is inserted into the fixed slots 34. At this time, the two fixed slots 34 can limit the two bases 1, thereby fixing the two bases 1 together. Personnel can assemble multiple bases 1 together through the above operations to meet the needs of using multiple DC power supplies 4 together, and the assembly method is simple and fast, ensuring that it is convenient for personnel to quickly assemble multiple DC power supplies 4.
