Latchable power supply

A latchable power supply is a power supply having a latch mechanism to control the opening and closing of a computer.

Since the popularity of single-player or online computer games is now rampant, the information on the Internet that pollutes the minds of schoolchildren is rapidly spreading and can be said to have no protection mechanism, causing schoolchildren or users who are not self-control to indulge in it. Long-term will cause personal physical and mental damage and increase social costs; on the other hand, parents have insufficient knowledge of computers, can not control or protect the time of schoolchildren or users who do not have the ability to use computers, thus having control over time Or restricting the previous creation of the website, "Management Device for Controlling Internet Browsing Website" of the Republic of China Patent Publication No. 586278, the creation comprising a logic control chip, a memory and an electrical connector, the electrical connector being connected The logic controls the chip, and uses the logic to control the chip to read the set storage data of the memory, and then accesses the setting of the Internet through the control of the application software to limit the time for the computer connected to the logic control chip to access the Internet and Restricted browsing of the website, this management device must be set by parental editing in advance The data is stored and stored on the logic control chip. However, most parents who are worried about controlling the computer do not know how to use the computer. Editing the settings and storing the data may cause confusion for parents and cannot be managed. Moreover, the creation The pluggable logic control chip can be easily disassembled, and it is actually difficult to achieve effective management. Other computer control is created, but the conventional creation method is too complicated and difficult to understand, that is, the installation cost is too high. Does not meet actual needs.

In view of the above-mentioned deficiencies, the object of the present invention is to provide a creation that can easily limit the opening of a computer and control the use time of the computer.

The present invention is a latchable power supply that converts an input power into a drive power to provide a computer operation, and the power supply has a latch mechanism having at least one switch And a lock unit, wherein the switch unit is disposed on the power line of the power supply from the input power to the drive power and has an open state that allows power to pass through the switch unit and an open state in which the power is turned off, the lock unit is Provided on the outside of the host computer and having an open state corresponding to the on state and a latched state corresponding to the open state, the user is allowed to operate the lock unit to interlock the switching unit to determine whether the power supply is activated to supply the drive power to the computer Host. Therefore, the user can use the latch mechanism to easily turn on or off the power supply to limit the function of the computer to open, thereby controlling the use time of the computer.

The detailed description and technical contents of the present invention will now be described with reference to the following drawings: Referring to FIG. 1, the present invention is a latchable power supply device that obtains an input power 7 and is subjected to an After the remote switch 31 is triggered, the input power 7 is converted into a driving power 8 to drive the hard disk device 4, the motherboard 5, the hard disk 6 and the like in the computer host 1 (shown in FIG. 3 and FIG. 4) to operate.

The electrical connection of the conversion unit 33 or the output unit 34 makes the power supply 3 unable to operate normally, and thus the host computer 1 cannot obtain the driving power 8. Moreover, the power conversion unit 33 further includes a power factor correction circuit 331 for adjusting the current phase of the input power 7, a pulse width modulation circuit 333 for providing a duty cycle signal, and an opening and closing controlled by the operation. The switching circuit 334 of the periodic signal is coupled to a transformer 332, and the opening and closing of the switching circuit 334 determines the period during which the input power 7 passes through the transformer 332. However, the above-mentioned power factor correction circuit 331, pulse width modulation circuit 333, switch circuit 334 and transformer 332 are also known in the art, so the operation principle will not be described again. In particular, the switching unit 21 is disposed between the power factor correction circuit 331, the transformer 332, the pulse width modulation circuit 333, or the switch circuit 334, and is configured to turn on or off the power factor correction circuit 331 and the transformer by the switching unit 21. 332, the electrical connection between the pulse width modulation circuit 333 or the switch circuit 334. Therefore, the latch mechanism 2 can control the electrical connection of the power supply device 3 by being disposed at both ends of the circuit, and the user can control the computer host 1 by controlling the latch mechanism 2 to open the circuit. The time to open. Please refer to FIG. 3 and FIG. 4 , which are schematic views of two embodiments of the latch mechanism 2 disposed on the computer main body 1 , wherein the power supply device 3 is mounted on the computer main body 1 , wherein the lock unit 22 It can be disposed on the outer casing of the power supply device 3, and the user can control the state of the lock unit 22 by using a matching key 9, thereby interlocking the switching unit 21 to be turned on or off; in addition, the lock unit 22 can also be disposed on the outer casing of the computer mainframe 1. The switching unit 21 is connected in series between the internal lines of the power supply 3, and the lock unit 22 interlocks the switching unit 21 to switch the on state or the open state, thereby controlling the opening and closing of the power supply 3, and the setting position of the lock unit 22. It is not limited to the front side of the computer host 1; the above-mentioned latching mechanism 2 allows the user to restrict the opening of the computer main body 1 in a simple manner, and the latching mechanism 2 cannot be easily removed, and the control can limit the schoolchildren or have no self-control ability. The time when the computer host 1 is used.

The above-mentioned lock unit 22 does not limit the type of the latch. The lock unit 22 can be a ball lock with a plurality of lock beads, or a lock, or a fingerprint lock, and can be an RF lock. The invention has been disclosed in the above preferred embodiments, and is not intended to limit the invention. Any modifications and refinements made by those skilled in the art without departing from the spirit and scope of the invention are intended to be included in the invention.
