Power switch device 18 is arranged on shell 12, power switch device 18 comprises a switch main body 26 and a switch key 28, switch main body 26 has a power supply end 30 and a ground connection end 32, as shown in Figure 2, power supply end 30 is coupled to power pins 22, ground connection end 32 is coupled to grounding pin 24, switch key 28 is to be coupled to basic computer 14, wherein switch key 28 be preferably a button handsetting to be mounted slidably on switch main body 26, use the position that optionally slides into switch main body 26 corresponding power ends 30 or ground connection end 32.Judgement control module 20 is coupled to basic computer 14 and power switch device 18, judgement control module 20 is used for according to the power supply state of basic computer 14, control the position that switch key 28 switches to corresponding power end 30 or ground connection end 32, use and set up or interrupt the power delivery between basic computer 14 and connectivity port 16, wherein judge that control module 20 can be by least one of them constructed forming of a software, a hardware and a firmware.
Control running for power switch device 18 is described in detail below, refer to Fig. 1, Fig. 2, and Fig. 3, the judgement control module 20 that Fig. 3 is use Fig. 2 of proposing according to one embodiment of the invention is controlled the process flow diagram of the switching of switch keys 28, and it comprises the following step.
Step 300: electronic installation is plugged on connectivity port 16;
Step 302: judge that control module 20 judges whether basic computer 14 is coupled to AC power or direct supply; If so, perform step 304; If not, execution step 306;
Step 304: judge that control module 20 judges whether electronic installation needs to receive the electric power transmitting from basic computer 14; If so, perform step 308; If not, execution step 310;
Step 306: judgement control module 20 is controlled the position that switch key 28 switches to the corresponding ground connection of switch main body 26 end 32;
Step 308: judgement control module 20 is controlled the position that switch key 28 switches to switch main body 26 corresponding power ends 30;
Step 310: judgement control module 20 is controlled the position that switch key 28 switches to the corresponding ground connection of switch main body 26 end 32.
At this, for above-mentioned steps, be described in detail.First, electronic installation (as mouse, portable disk etc.) is being plugged on connectivity port 16 after (step 300), judgement control module 20 will start to judge that the power supply state (step 302) of basic computer 14 usings as the reference frame of controlling switch key 28 and switch to the position of switch main body 26 corresponding power ends 30 or ground connection end 32.When judgement control module 20 is judged basic computer 14 and is not coupled to AC power or direct supply, judge that control module 20 will control the position (step 306) that switch key 28 slides into the corresponding ground connection of switch main body 26 end 32 according to this, to interrupt the power delivery between basic computer 14 and connectivity port 16, now, electronic installation will receive via connectivity port 16 electric power that basic computer 14 transmits, so can solve and mentionedly in prior art can consume constantly the power wastage problem that the electric power of portable computer device causes via connectivity port because of electronic installation.
In addition, when judgement control module 20 is judged basic computer 14 and is coupled to AC power or direct supply, for example basic computer 14 via external AC power supply line to be coupled to AC power or dc-battery be directly installed, judge that control module 20 will further judge whether electronic installation needs to receive the electric power transmitting from basic computer 14, in more detail, when judgement control module 20 is judged further electronic installation and is not needed to receive the electric power transmit from basic computer 14, such as electronic installation, charged complete etc., judge that control module 20 controls the position (step 310) that switch key 28 slides into the corresponding ground connection of switch main body 26 end 32 according to this, to interrupt the power delivery between basic computer 14 and connectivity port 16, now, electronic installation will receive via connectivity port 16 electric power that basic computer 14 transmits, so can solve and mentionedly in prior art can consume constantly the power wastage problem that the electric power of portable computer device causes via connectivity port because of electronic installation.On the other hand, when judgement control module 20 is judged electronic installation and need to be received the electric power transmitting from basic computer 14, for example electronic installation basic computer 14 in shutdown, when sleep or holding state, still need to proceed charging or still must continue that running operates for user etc., judge that control module 20 will control the position (step 308) that switch key 28 slides into switch main body 26 corresponding power ends 30 according to this, to set up the power delivery between basic computer 14 and connectivity port 16, now, electronic installation just can normally operate or proceed via connectivity port 16 charging with the electric power that successfully receives basic computer 14 and transmitted.As for above-mentioned judgement control module 20, control the design that switch keys 28 slide, it can adopt the control mode being common in prior art, such as carrying out with hardware or software control mode etc., therefore do not repeat them here.
In addition, the mode that portable computer device 10 is used for controlling the switching of switch key 28 can be not limited to the automatic decision of above-mentioned use judgement control module 20 and control design, it also can change to adopt and carry out with artificial judgment control mode, in other words, in other embodiments, portable computer device 10 can allow user to judge voluntarily whether the power supply state of basic computer 14 and electronic installation need to receive the electric power transmitting from basic computer 14 and the blocked operation that carries out switch key 28 with manual mode, for instance, when user judges basic computer 14 and has been coupled to AC power or direct supply and electronic installation and need to receives the electric power transmitting from basic computer 14 at present, user can utilize the mode of manual control that switch key 28 is dialed to the position of switch main body 26 corresponding power ends 30 so that electronic installation can successfully receive via connectivity port 16 electric power that basic computer 14 transmits, otherwise, when user judges basic computer 14 and is not coupled to AC power or direct supply, user can utilize the mode of manual control switch key 28 to be dialed to the position of the corresponding ground connection of switch main body 26 end 32, so that electronic installation can no longer be depleted to the electric power of basic computer 14 own via connectivity port 16, thereby reach energy saving effect.As for other related description, it can be analogized with reference to above-described embodiment, therefore do not repeat them here.
