Description

  The present invention relates to a peripheral device, and more particularly to a keyboard capable of controlling the heat dissipation efficiency of a heat dissipation device inside a host device.

  As scientific technology advances, personal computers have become increasingly popular, but personal computer host devices are usually hermetically sealed. When the host device operates, a member inside the host device generates heat, thereby increasing the temperature inside the host device. When the temperature inside the host device is too high, a crash is likely to occur.

  In order to overcome the problem of temperature rise, a general method is to install a heat dissipation unit inside the host device. However, it is difficult to control the heat dissipation unit. In order to adjust the heat dissipation efficiency of the heat dissipation unit, the user may have to use specific application software. Inability to immediately release heat energy may cause a crash.

  The objective of this invention provides the keyboard and computer system which have an adjustment function.

  The present invention provides a keyboard having an adjustment function used for adjusting the heat dissipation efficiency of a heat dissipation unit in a host device. The keyboard of the present invention includes a switching unit that can be switched to a different state, a control unit that generates a control signal based on the state of the switching unit, and a control signal that is sent to the host device. And a communication port for adjusting the heat dissipation efficiency of the heat dissipation unit.

  The present invention provides another computer system. The computer system of the present invention includes a host device having a heat dissipation unit, a keyboard having a switching unit, and a control unit that generates a control signal based on the state of the switching unit. The host device adjusts the heat dissipation efficiency of the heat dissipation unit based on the control signal.

  According to the keyboard and the computer system of the present invention, the user can adjust the heat radiation efficiency of the heat radiating member inside the host device with the keyboard without moving the position. Therefore, since the heat dissipation efficiency of the host device can be adjusted immediately, it is possible to avoid the occurrence of a crash due to the temperature of the host device being too high, and the power consumption of the host device can be appropriately reduced. Therefore, convenience can be greatly improved.

It is the schematic which shows the computer system of this invention. It is an implementation example which shows the keyboard external appearance of this invention. It is a block diagram of the computer system of this invention.

  In order that the objects, features, and advantages of the present invention will be more clearly understood, embodiments will be described below in detail with reference to the drawings.

  FIG. 1 is a schematic diagram of a computer system of the present invention. As shown in the figure, the computer system 10 includes a host device 11 having a heat dissipation unit 111, a keyboard 13, a control unit 15, and a monitor 17. In the present embodiment, the heat dissipation unit 111 includes at least one heat dissipation member. Each heat dissipating member can release heat energy generated by a different electronic member. The present invention does not limit the type of heat dissipation member. In some embodiments, the heat dissipation member is an active heat dissipation member, for example, a fan or a water cooler.

  In the present embodiment, the keyboard 13 has a switching unit 131 used for adjusting the heat dissipation efficiency of the heat dissipation unit 111. Therefore, the heat energy inside the host device 11 can be discharged immediately. In one implementation, the switching unit 131 comprises at least one analog switch and / or at least one digital switch. The present invention does not limit the types of analog switches and digital switches. The analog switch includes a multi-stage turning knob, a DIP switch, and a button. The digital switch includes a touch panel.

  The control unit 15 connects the keyboard 13 and the host device 11 and is used to generate a control signal based on the state of the switching unit 131. A connecting line 191 sends a control signal to the host device 11. The host device 11 adjusts the heat dissipation efficiency of the heat dissipation unit 111 based on the control signal.

  For example, when the temperature inside the host device 11 rises, the user can immediately release the heat energy inside the host device 11 by adjusting the state of the switching unit 131 to increase the heat radiation efficiency of the heat radiation unit 111. Can do. Conversely, when the temperature inside the host device 11 decreases, the user can reduce the power consumption of the heat dissipation unit 111 by adjusting the state of the switching unit 131 to lower the heat dissipation efficiency of the heat dissipation unit 111. . As an example, when the heat radiating member is a fan, when the temperature in the host device 11 is high, the temperature in the host device 11 is lowered by increasing the number of rotations of the fan to increase the heat radiation efficiency, thereby reducing the temperature in the host device 11. When the temperature is appropriate, the fan speed is decreased to lower the heat dissipation efficiency.

  In this embodiment, the host device 11 has a function of monitoring temperature. The user can know the current internal temperature of the host device 11 through the BIOS basic input / output system (BIOS) or specific application software of the operating system (OS). In one possible implementation, the current internal temperature of the host device 11 can be represented by the monitor 17. In another embodiment, a display panel is provided on the keyboard 13 to represent the current internal temperature of the host device 11 and / or the operating state of the heat dissipation unit 111.

  In the present embodiment, the control unit 15 has a pulse-width modulated integrated circuit (PWMIC). Therefore, the control signal generated by the control unit 15 is a pulse width modulation signal. In FIG. 1, the control unit 15 is independently installed outside the keyboard 13. In another embodiment, the control unit 15 can be integrated into the keyboard 13. In this case, the connection line 192 between the keyboard 13 and the control unit 15 can be omitted.

  FIG. 2 is a practical example of the appearance of the keyboard of the present invention. In this embodiment, the switching unit 131 includes switches 211 and 212. The switch 211 is used to select one heat radiating member of the heat radiating unit 111. For example, when the heat radiating unit 111 in the host device 11 has a plurality of heat radiating members, one heat radiating member can be selected by the switch 211 to adjust the heat radiating efficiency. Conversely, when the efficiency of all the heat radiating members is not individually controlled, the switch 211 can be omitted.

  The switch 212 is used to adjust the heat dissipation efficiency of a specific heat dissipation member. After the switch 211 selects one heat dissipating member, the switch 212 can adjust the heat dissipating efficiency of the selected heat dissipating member. In another implementation, the switch 211 can be omitted. In this case, the heat radiation efficiency of all the heat radiating members can be adjusted by the switch 212.

  In this embodiment, the switches 211 and 212 are both multi-stage turning knobs, but the present invention is not limited thereto. In other embodiments, the switches 211 and 212 are different types of switches.

  In this embodiment, the keyboard 13 further includes a display panel 220. The display panel 220 can represent the heat dissipation efficiency of a heat dissipation member (for example, the fan 1 or the fan 2). In other embodiments, the display panel 220 further represents the internal temperature of the host device 11, so that the user adjusts the heat dissipation efficiency of the heat dissipation member in a timely manner, so that the internal temperature of the host device 11 becomes too high. Can be avoided.

  In the present embodiment, the user can select and adjust a specific heat radiating member by the switches 211 and 212. In another embodiment, the user can select and adjust a specific heat radiating member through the display panel 220. For example, the display panel 220 is a touch panel. The user can select a certain heat radiating member by touching the display panel 220 and adjust the efficiency of the selected heat radiating member.

  In other embodiments, the switching unit 131 may further provide a switching function, in addition to the switching unit 131 being able to adjust the heat dissipation efficiency of the heat dissipation unit 111. In one embodiment, the switching unit 131 may be a mode switch ( (Not shown). When the mode switch is switched to the manual state, the host device 11 adjusts the heat dissipation efficiency of the heat dissipation unit 111 based on the control signal output to the control unit 15. When the mode switch is switched to the automatic state, the host device 11 automatically adjusts the heat radiation efficiency of the heat radiation unit 111.

  In another possible embodiment, the switch 211 can further select to adjust the heat dissipation efficiency of the heat dissipation unit 111 manually or automatically, in addition to selecting a heat dissipation member. For example, when the switch 211 is switched to the automatic state, the heat dissipation efficiency of the heat dissipation unit 111 is adjusted by a controller (not shown) inside the host device 11. When the switch 211 leaves the automatic state, the host device 11 adjusts the heat dissipation efficiency of the heat dissipation unit 111 based on the output signal of the control unit 15.

  FIG. 3 is a block diagram of the computer system of the present invention. In the present embodiment, the control unit 15 is integrated into the keyboard 13, but the present invention is not limited thereto. In other embodiments, the control unit 15 can be independently installed outside the keyboard 13. As shown in the figure, the keyboard 13 includes a switching unit 131, a display panel 132, control units 15 and 133, and a communication port 134.

  The control unit 133 has a keyboard controller (KBC) and is used to send a signal corresponding to the pressed key to the host device 11. The operating principle of the keyboard controller is well known to those skilled in the art and will not be repeated here.

  The control unit 15 generates a control signal Sc based on the switching state of the switching unit 131. The communication port 134 sends a control signal Sc to the host device 11. The host device 11 adjusts the heat dissipation efficiency of the heat dissipation unit 111 based on the control signal Sc. Further, the communication port 134 sends key information output from the control unit 133 to the host device 11.

The display panel 132 can represent the temperature inside the host device 11. In this embodiment, the host device 11 sends the temperature information _ST to the control unit 15 through the communication port 134. The control unit 15 based on the temperature information _{S T,} by controlling the display panel 132 represents the temperature of the host device 11 to the display panel 132.

  In another embodiment, the host device 11 provides the heat dissipation efficiency of the heat dissipation unit 111 to the control unit 15 through the communication port 134. The control unit 15 controls the display panel 132 to display the heat dissipation efficiency of the heat dissipation unit 111 on the display panel 132. However, the display panel 132 is never necessary. In other embodiments, the temperature of the host device 11 or the heat dissipation efficiency of the heat dissipation unit 111 can be expressed by another display device (for example, a monitor).

  The user can adjust the heat radiation efficiency of the heat radiating member inside the host device with the keyboard without moving the body. Therefore, since the heat dissipation efficiency of the host device can be adjusted immediately, it is possible to avoid the occurrence of a crash due to the temperature of the host device being too high, and the power consumption of the host device can be appropriately reduced. Therefore, convenience can be greatly improved.

  The preferred embodiments of the present invention have been described above, but this does not limit the present invention, and a few changes and modifications that can be made by those skilled in the art without departing from the spirit and scope of the present invention. Can be added. Therefore, the protection scope claimed by the present invention is based on the claims.
