Utility model content
The purpose of this utility model is to provide a kind of laptop electric power button indicating lamp display system, solves the problem that quick and precisely cannot find notebook computer button in prior art under dark surrounds.
According to an aspect of the present utility model, provide a kind of laptop electric power button indicating lamp display system, comprising:
Be arranged on the indicator light at laptop electric power button positions place;
Be arranged on the transducer of the situation of opening for detecting notebook computer upper cover on notebook computer;
Be connected to the power control between described indicator light and described transducer, correspond to the power supply starting signal opened of notebook computer upper cover for what export according to transducer, be used for described indicator light supply the power supply that indicator light lighted or glimmers.
Preferably, described transducer is Hall element.
Preferably, described transducer is displacement transducer.
Preferably, described power control is embedded controller.
Preferably, also comprise:
Be connected to the supply unit of described indicator light input and described sensor input, for being respectively described indicator light and described transducer provides power supply.
Preferably, the input of described supply unit connects the output of power control.
Preferably, described power control comprises:
AD conversion unit, converts digital power enabling signal to for the analog power enabling signal exported by transducer;
Control unit, sends be used for supplying the indicator light power supply signal lighting or glimmer for controlling described supply unit according to converted to digital power enabling signal.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is simple and convenient, especially accurately can press laptop electric power button fast in the environment of dark, brings conveniently, and improve Consumer's Experience to user.
Below in conjunction with accompanying drawing, structure of the present utility model and principle are described in detail.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of laptop electric power button indicating lamp display system that the utility model embodiment provides;
Fig. 2 is the circuit diagram of the laptop electric power button indicating lamp display system that the utility model embodiment provides.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, should be appreciated that following illustrated preferred embodiment is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Fig. 1 shows the schematic diagram of a kind of laptop electric power button indicating lamp display system that the utility model embodiment provides, and as shown in Figure 1, comprising: the indicator light 103 being arranged on laptop electric power button positions place; Be arranged on the transducer 101 of the situation of opening for detecting notebook computer upper cover on notebook computer; Be connected to the power control 102 between described indicator light 103 and described transducer 101, correspond to the power supply starting signal opened of notebook computer upper cover for what export according to transducer, be used for described indicator light supply the power supply that indicator light lighted or glimmers.
Wherein, described transducer 101 is Hall element or displacement transducer; Described power control is embedded controller.
The utility model also comprises: the supply unit being connected to described indicator light input and described sensor input, for being respectively described indicator light and described transducer provides power supply.Wherein, the input of described supply unit connects the output of power control.
Wherein, described power control 102 comprises: AD conversion unit, converts digital power enabling signal to for the analog power enabling signal exported by transducer; Control unit, sends be used for supplying the indicator light power supply signal lighting or glimmer for controlling described supply unit according to converted to digital power enabling signal.
Fig. 2 shows the circuit diagram of the laptop electric power button indicating lamp display system that the utility model embodiment provides, as shown in Figure 2, under the state of notebook computer shutdown closing lid, the upper cover of notebook computer whether is opened by the transducer Real-Time Monitoring user on main board for notebook computer, when detecting in the overshoot that the upper cover of notebook computer is opened, transducer on main board for notebook computer will detect that upper cover opening signal is sent in embedded controller, the upper cover opening signal that embedded controller sends according to transducer, the power supply signal that the LED light being used for laptop electric power button is shinny or glimmer is sent to power supply, so that the LED light of laptop electric power button is shinny or flicker.That is, in the process that upper cover is opened, the transducer on computer main board is activated, and EC (Embedded Controller, embedded controller) triggers laptop electric power button LED light point and flashes 5 seconds.
The utility model can also be realized by amendment EC code:
Shut down of computer → transducer is that trigger source → computer upper cover is opened → wake up EC → EC and checks state → light power knob LED.
In sum, the utility model has following technique effect:
After notebook computer upper cover of the present utility model is opened, the LED light point on power knob flashes 5 seconds, is convenient to user and under dark surrounds, recognizes power knob rapidly and accurately and open computer, easy to use, and improves Consumer's Experience.
Although be described in detail the utility model above, the utility model has been not limited thereto, and those skilled in the art of the present technique can carry out various amendment according to principle of the present utility model.Therefore, all amendments done according to the utility model principle, all should be understood to fall into protection range of the present utility model.
