Description

Technical Field

[0001] This invention relates to the field of monitoring power supply technology, and in particular to a low-power, high-reliability monitoring power supply. Background Technology

[0002] Computers are low-voltage products, meaning their components operate at relatively low voltages, typically within ±12 volts, and use direct current (DC). Ordinary AC mains power is 220 volts (110 volts in some countries), which cannot be directly used on computer components. Therefore, like many household appliances, computers require a power supply unit to convert AC mains power into a usable voltage. This unit is usually installed inside the computer. The core components of a computer operate at very low voltages, and because computers operate at very high frequencies, the power supply requirements are relatively high. Currently, computer power supplies use switching circuits to convert AC to DC, and then use choppers to control the voltage, outputting different voltages to computer components such as the motherboard, hard drive, and optical drive.

[0003] For example, Chinese Patent CN211015401U discloses an intelligent monitoring power supply, including a power supply unit, a mounting base, a dust extraction hole, and a collection component. The mounting base is fixedly connected to the bottom front and back of the power supply unit. A dust removal mechanism is fixedly connected to the inner wall of the top of the power supply unit. A heat dissipation mechanism is fixedly connected to the middle part of the power supply unit. The heat dissipation mechanism is located on the inner wall of the top of the power supply unit and is fixedly connected to the power supply unit. The heat dissipation mechanism can dissipate the heat generated inside the power supply unit to ensure the normal operation of the power supply. Through the through holes on the outside of the exhaust chamber, air is discharged into the power supply unit, and the hot air inside the power supply unit is squeezed out through the fine mesh to achieve the effect of reducing the internal temperature of the power supply. Moreover, the exhaust holes of the exhaust chamber are set in different positions, which can perform air cooling for various components inside the power supply unit, effectively improving the heat dissipation performance of the power supply.

[0004] The existing technology has the following problems:

[0005] The monitoring power supply is not equipped with any shock-absorbing components. Since the monitoring power supply is usually placed inside a chassis, which is an unsecured device, it is easily moved by external influences, causing external vibrations to be transmitted to the power supply, resulting in damage to the internal components of the power supply.

[0011] Preferably, the protective shell has disassembly holes on its front and rear sides near the left and right sides, and the disassembly holes are located on the upper end of the card plate away from the dust removal plate.

[0012] Preferably, the inner sides of the left and right walls of the placement box are fixedly connected to limit rods on both the front and back sides, and the limit rods are located on the side of the card plate away from the dust removal plate. A top plate is movably sleeved on the outer side of the limit rods, and the top plate is located on the side of the card plate close to the dust removal plate. A push rod is fixedly connected to the upper side of the top plate away from the power supply body.

By inserting the rod into the disassembly hole, the clamping plate is made to contact the housing, allowing the housing to be removed from the inside of the protective shell, thus enabling the dust removal plate to be replaced and maintained.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 , Figure 2 As shown, a low-power, high-reliability monitoring power supply includes a protective housing 1. Four rectangular support bases 2 are fixedly connected to the lower side of the protective housing 1 near the four corners. Two symmetrical ventilation mechanisms 3 are movably sleeved on the inner side of the protective housing 1 near the left and right sides. A shock-absorbing mechanism 4 is connected to the lower surface of the lower side of the protective housing 1. A power supply body 5 is fixedly connected to the upper side of the shock-absorbing mechanism 4. A heat sink 6 is fixedly connected to the upper side of the power supply body 5.

[0029] It should be noted that the heat sink 6 is used to absorb the heat generated by the power supply body 5 and increase the contact area between the heat-generating area of ​​the power supply body 5 and the air, thereby improving the heat dissipation efficiency.

[0030] like Figure 2 , Figure 3 As shown, the ventilation mechanism 3 includes a placement box 31, a dust removal plate 36 is movably sleeved on the inner side of the placement box 31, the outer side of the placement box 31 is movably sleeved on the inner side of the protective shell 1 near the left and right sides, a protruding frame 32 is fixedly sleeved on the inner side of the protective shell 1 near the left and right sides, and the protruding frame 32 is located on the side of the placement box 31 near the power supply body 5, and a cooling fan 33 is movably installed on the inner side of the protective shell 1 near the left and right sides, and the cooling fan 33 is located on the side of the protruding frame 32 near the power supply body 5.

[0031] It should be noted that the dust removal plate 36 is used to absorb dust in the air passing through it, preventing the dust from falling on the power supply body 5 and the heat sink 6. The cooling fan 33 is used to accelerate the air circulation inside the protective shell 1, thereby removing the heat from the heat sink 6 and accelerating the heat dissipation of the power supply body 5.

[0032] like Figures 2-4As shown, four rectangularly distributed fixing components 35 are movably sleeved on the inner sides of the left and right walls of the placement box 31. Each fixing component 35 includes a retaining plate 351. The outer side of the retaining plate 351 is movably sleeved on the inner sides of the left and right walls of the placement box 31. The lower end of the retaining plate 351 is rotatably connected to the front and rear sides of the inner sides of the left and right walls of the placement box 31. Two first springs 352 distributed in the front and rear are movably installed on the lower end of the retaining plate 351. The side of the retaining plate 351 away from the dust removal plate 36 is movably sleeved in the fixing grooves on the front and rear sides of the inner side of the protective shell 1, near the left and right sides.

[0033] It should be noted that when the card plate 351 is inserted into the inner side of the fixing groove, the placement box 31 is fixed inside the protective shell 1. The first spring 352 is a torsion spring. The setting of the first spring 352 avoids the problem of damage to the parts due to the elasticity of the material itself.

[0034] like Figure 4 As shown, the protective housing 1 has disassembly holes 353 on the front and back sides near the left and right sides, and the disassembly holes 353 are located on the upper end of the card plate 351 away from the dust removal plate 36.

[0035] It should be noted that inserting the rod into the inside of the disassembly hole 353 causes the upper end of the card plate 351 to be pushed, causing the card plate 351 to disengage from the fixing groove, so that the placement box 31 can be removed from the inside of the protective shell 1.

[0036] like Figures 3-5 As shown, limit rods 355 are fixedly connected to the inner sides of the left and right walls of the placement box 31, and the limit rods 355 are located on the side of the card plate 351 away from the dust removal plate 36. A top plate 354 is movably sleeved on the outer side of the limit rods 355, and the top plate 354 is located on the side of the card plate 351 close to the dust removal plate 36. A push rod 357 is fixedly connected to the upper side of the top plate 354 away from the power supply body 5. A second spring 356 is movably sleeved on the outer side of the limit rods 355, and the second spring 356 is located on the side of the top plate 354 away from the power supply body 5.

[0037] It should be noted that the second spring 356 is a tension spring. When the clamping plate 351 rotates to a vertical position, the top plate 354 is no longer blocked by the clamping plate 351, causing the second spring 356 to pull the top plate 354 to move away from the power supply body 5. This causes the top plate 354 to block the clamping plate 351, preventing the clamping plate 351 from resetting. Pressing the push rod 357 instructs the top plate 354 to reset, and then the first spring 352 drives the clamping plate 351 to reset.

[0038] like Figures 1-3 As shown, a groove 34 is provided on the left side of the placement box 31 near the middle of the upper edge, and a friction texture is provided on the lower middle of the placement box 31. A notch is provided on the lower middle of the protective shell 1 near the left and right edges.

[0039] It should be noted that the groove 34 is used to facilitate the removal of the dust removal plate 36 from the inside of the placement box 31, and the notch is designed so that the placement box 31 can be pulled out from the inside of the protective shell 1.

[0040] like Figure 2 , Figure 6 As shown, the shock absorption mechanism 4 includes a mechanism box 41. Four rectangular corner platforms 42 are attached to the lower side of the mechanism box 41 near the four corners. The lower side of the corner platforms 42 is fixedly connected to the lower inner surface of the protective shell 1 near the front and rear sides. A third spring 43 is fixedly connected to the inner vertical surface of each of the four corner platforms 42. The side of the third spring 43 near the power supply body 5 is fixedly connected to the outer side of the mechanism box 41 near the four corners.

[0041] It should be noted that the third spring 43 is a shock-absorbing spring with internal damping components, which causes the third spring 43 to absorb the lateral force on the power supply body 5 due to vibration.

[0042] like Figure 2 , Figure 6 As shown, a fixed seat 45 is movably sleeved on the outer side of the mechanism box 41, and several evenly distributed fourth springs 44 are fixedly connected to the lower inner surface of the mechanism box 41. The upper side of the fourth springs 44 is fixedly connected to the upper inner surface of the fixed seat 45, and the lower side of the power supply body 5 is fixedly connected to the upper side of the fixed seat 45.

[0043] It should be noted that the mounting base 45 is a shock-absorbing spring with internal damping components, which causes the mounting base 45 to absorb the vertical force on the power supply body 5 due to vibration.

[0044] The working principle of this invention is as follows: First, the third spring 43 is a shock-absorbing spring containing a damping component, which absorbs the lateral force on the power supply body 5 caused by vibration. The fixing base 45 is also a shock-absorbing spring containing a damping component, which absorbs the vertical force on the power supply body 5 caused by vibration. Through the absorption of external vibrations by the third spring 43 and the fourth spring 44, the impact on the power supply body 5 is dissipated, thus protecting the power supply body 5 and preventing damage to internal components or poor wire connection caused by vibration. Then, the heat sink 6 is used to absorb... The heat generated by the power supply body 5 is absorbed, and the contact area between the heat-generating area of ​​the power supply body 5 and the air is increased to improve heat dissipation efficiency. The dust removal plate 36 is used to absorb dust in the air passing through it, preventing this dust from falling on the power supply body 5 and the heat sink 6. The cooling fan 33 is used to accelerate the air circulation inside the protective shell 1, thereby removing the heat from the heat sink 6 and accelerating the heat dissipation of the power supply body 5. The cooling fan 33 drives the air to circulate quickly from the inside of the protective shell 1, so that the heat generated by the power supply body 5 during operation is removed, allowing the power supply body 5 to be cooled down quickly, so that the power supply body 5 can operate for a long time. Finally, when the card plate 351 is locked... When the box 31 is placed inside the fixing slot, it is fixed inside the protective shell 1. The first spring 352 is a torsion spring. The design of the first spring 352 avoids the problem of damage to the components due to the elasticity of the material itself. The rod is inserted into the inside of the disassembly hole 353, which pushes the upper end of the clamping plate 351, causing the clamping plate 351 to disengage from the fixing slot, so that the box 31 can be removed from the inside of the protective shell 1. The second spring 356 is a tension spring. When the clamping plate 351 is rotated to a vertical position, the top plate 354 is no longer blocked by the clamping plate 351, so that the second spring 356 pulls the top plate 354 away from the power source. The top plate 354 moves to one side, causing the top plate 354 to block the card plate 351, preventing the card plate 351 from resetting. Pressing the push rod 357 instructs the top plate 354 to reset, and then the first spring 352 drives the card plate 351 to reset. The pull groove 34 is used to facilitate the removal of the dust removal plate 36 from the inside of the placement box 31. The notch allows the placement box 31 to be pulled out from the inside of the protective shell 1. By inserting the rod from the inside of the disassembly hole 353, the card plate 351 is contacted to fix the placement box 31, allowing the placement box 31 to be removed from the inside of the protective shell 1, thereby replacing and maintaining the dust removal plate 36. The operation is simple, disassembly is convenient, and installation is quick.
