[0024] The present invention will be further described in detail below with reference to embodiments:
[0025] like Figures 1-6 As shown, this utility model provides a computer power supply with an automatic power-off alarm function when tipped over, including a support component 1 and a power-off component 2. The support component 1 includes a power supply housing 10 and a circuit board 14. The circuit board 14 is fixedly installed inside the power supply housing 10. A fixing hole 11 is fixedly connected to the bottom of the power supply housing 10, through which the computer power supply is fixed inside the chassis. A power connection cable 12 is fixedly installed inside the power supply housing 10. A power supply body 13 is fixedly installed inside the power supply housing 10. The circuit board 14 is fixedly installed inside the power supply housing 10. A vent 16 is opened inside the power supply housing 10. A cooling fan 15 is fixedly installed inside the power supply housing 10, through which the cooling fan 15 and the vent 16 dissipate heat from the power supply body 13 when it is working.
[0026] like Figures 2-6As shown, the power-off assembly 2 is fixedly installed inside the support assembly 1. The power-off assembly 2 includes a hollow column 23 and a swing column 26. The swing column 26 is movably installed inside the hollow column 23. The hollow column 23 is fixedly installed inside the power supply housing 10. A normally open relay 24 is fixedly installed inside the power supply housing 10. A buzzer 21 is fixedly installed on one side of the power supply housing 10. The buzzer 21 emits a sound to remind the user that the computer power supply is tilted or tipped over. A terminal block 22 is fixedly installed inside the power supply housing 10. A fixed contact 29 is fixedly installed inside the power supply housing 10. A movable contact is slidably installed inside the power supply housing 10. Contact 28, the movable contact 28 has a connecting slot 202 inside, and an electromagnet 27 is fixedly installed inside the power supply housing 10. When the computer power supply tilts or falls over, the swing column 26 swings inside the hollow column 23, contacts the conductive arc plate 25, closes the normally open relay 24, conducts the power-off circuit, energizes the electromagnet 27, separates the movable contact 28 from the fixed contact 29, disconnects the computer power supply, and makes the buzzer 21 sound to remind the user. Through the combined action of the swing column 26, the conductive arc plate 25 and the buzzer 21, accidents such as fires caused by heat accumulation inside the computer power supply after it falls over are prevented.
[0027] A movable block 203 is slidably installed inside the power supply housing 10. A connecting spring 201 is provided on the top of the movable block 203. A conductive arc-shaped plate 25 is fixedly installed inside the hollow column 23. The hollow column 23 is fixedly installed inside the power supply housing 10. A toggle lever 20 is fixedly installed on the outside of the movable block 203. When the power circuit is turned on after a power outage, the movable contact 28 moves under the action of the electromagnet 27, pushing the movable block 203 upward and then falling into the connecting slot 202, locking the movable contact 28. Under the action of the connecting spring 201, the movable contact 28 can only be brought into contact with the fixed contact 29 by manually pulling the toggle lever 20. Through the combined action of the electromagnet 27, the movable contact 28, and the movable block 203, accidental contact between the fixed contact 29 and the movable contact 28 is prevented when the power is off, thus improving the safety of use.
[0028] The working principle of this computer power supply with automatic power-off alarm function when tipped over will be explained in detail below.
[0029] like Figures 1-6As shown, when using this computer power supply with automatic power-off alarm function upon tipping, the power supply is fixed inside the chassis through the fixing hole 11. When the power supply is working, the cooling fan 15 and ventilation holes 16 dissipate heat from the main body 13. When the power supply tilts or tipes over, the swing column 26 swings inside the hollow column 23, contacting the conductive arc plate 25, causing the normally open relay 24 to close, thus completing the power-off circuit. This energizes the electromagnet 27, separating the moving contact 28 from the fixed contact 29, disconnecting the power supply, and causing the buzzer 21 to sound, alerting the user. The combined action of the plate 25 and the buzzer 21 prevents accidents such as fires caused by heat buildup inside the computer power supply after it is tilted. When the power-off circuit is turned on, the electromagnet 27 causes the movable contact 28 to move, pushing the movable block 203 upward and then falling into the connecting slot 202, locking the movable contact 28. Under the action of the connecting spring 201, the movable contact 28 can only be brought into contact with the fixed contact 29 by manually pulling the lever 20. Through the combined action of the electromagnet 27, the movable contact 28, and the movable block 203, accidental contact between the fixed contact 29 and the movable contact 28 is prevented when the power is off, thus improving the safety of use.
[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
