Description
Technical field
The utility model relates to a kind of all-in-one, refers in particular to a kind of integrated computer with low-power consumption mouse.
Background technology
The mouse of existing integrated computer band is in order to energy-conservation, all adopt timing mode, after a period of time is not mobile, just close the photodiode (when moving for mouse, reflection ray, is dissipative cell) of mouse discontinuously, one is power saving, one is just enter after detection has movement to continue to light photodiode again, have two problems like this, one is interrupted closedown and still wants consumed energy, and one is to respond in time.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of integrated computer with low-power consumption mouse, solves the problem that the mouse energy consumption of existing computer is high.
The utility model is achieved in that
A kind of integrated computer with low-power consumption mouse, comprise main frame, described main frame one side is provided with display screen, main frame inside is provided with mainboard, and the mouse to be connected with mainboard, described mouse inner upper has the support column of a hollow, one end of described support column is embedded in top cap of mouse, the other end of support column is connected with the probe of human body infrared inductor, mouse inside also comprises energy-saving circuit, energy-saving circuit comprise comparer and with door chip, the in-phase input end of comparer is connected with the output terminal of human body infrared inductor, the reverse input end of comparer is connected with comparison reference voltage, the output terminal of comparer is connected with an input end of door chip, be connected with the output terminal of photoelectricity driving circuit with another input end of door chip, be connected with the positive pole of mouse photodiode with the output terminal of door chip, the negative pole of mouse photodiode is connected with power cathode.
The utility model has the advantage of: this integrated computer, after hand leaves mouse, just closes mouse photodiode, greatly reduces mouse energy consumption, reaches the object reducing power consumption.On holding after mouse, namely enter the wait-for-response stage, fast response time.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the profile schematic diagram of the utility model energy-saving mouth.
Fig. 3 is the circuit diagram of the circuit in the utility model.
Embodiment
Refer to shown in Fig. 1 to Fig. 3, a kind of integrated computer with low-power consumption mouse, comprise main frame 1, main frame 1 one side is provided with display screen 2, main frame 1 inside is provided with mainboard 3, and the mouse 11(to be connected with mainboard 3 schemes not shown), mouse 11 inner upper has the support column 12 of a hollow, one end of support column 12 is embedded in mouse 11 upper cover, the other end of support column 12 is connected with the probe 13 of human body infrared inductor, mouse 11 inside also comprises energy-saving circuit, energy-saving circuit comprise comparer U1 and with door chip U2, the in-phase input end of comparer U1 is connected with the output terminal of human body infrared inductor, the reverse input end of comparer U1 is connected with comparison reference voltage, the output terminal of comparer U1 is connected with an input end of door chip U2, be connected with the output terminal of photoelectricity driving circuit with another input end of door chip U2, be connected with the positive pole of mouse photodiode L1 with the output terminal of door chip U2, the negative pole of mouse photodiode L1 is connected with power cathode.Wherein, comparison reference voltage is made the voltage that human body infrared inductor exports for comparer and being compared, and comparison reference voltage has multiple implementation, and reference voltage chip can be used to realize, or resistance R1 and resistance R2 dividing potential drop as shown in Figure 3, can be used to realize.Comparison reference voltage should not be selected too low, generally can select more than 1V's.As in the circuit of Fig. 3, if positive source is 5V, then resistance R1 can select the resistance of 40K, and resistance R2 can select the resistance of 10K.The power supply of comparer U1 directly can select the power supply of USB.Mouse photodiode L1 is placed on mouse lower middle position 14 place.Wherein, human body infrared inductor is existing element, and it has probe, can export high level after sensing human body infrared, and do not sense then output low level, the utility model is not repeated herein.
In certain embodiments, these elements can select following model: power supply selects the 5V power supply of USB, and comparer U1 selects TL393, selects 7408 with door chip, select the rated operational voltage of mouse photodiode L1 with door chip power supply voltage.The utility model in use, when holding on mouse, human body infrared can arrive on the probe of human body infrared inductor by the hollow of support column, now human body infrared inductor exports high level, comparer U1 exports high level, then driving with an input end of door chip U2 is high level, when now photoelectricity driving circuit is high level, then export as high level with door chip U2, when now photoelectricity driving circuit is low level, export as low level with door chip U2, namely photoelectricity driving circuit (i.e. the circuit of mouse-driven photodiode work) can driven mouse photodiode L1, namely when staff uses mouse, mouse can normally work.When staff leaves mouse, namely without after mouse, the probe of human body infrared inductor then cannot sense, human body infrared inductor output low level, comparer U1 output low level is low level with an input end of door chip, then with door chip output low level always, now mouse photodiode L1 is in closed condition completely, saves electricity, makes mouse have low-power consumption.When hand is got back on mouse, mouse photodiode L1 can enter the state of being driven normally rapidly, improves the response time, and now mouse does not also start mobile, solves existing mouse and wants discontinuity detection just can enter the corresponding slow problem of normal work after mobile.Support column of the present utility model can block the infrared of other positions of human body, avoids the infrared impact on mouse in other positions of human body.
In certain embodiments, mouse of the present utility model is wireless mouse, and namely the connected mode of mouse and main frame is wireless connections, and mouse uses powered battery, uses the energy-saving circuit in this integrated computer greatly can also extend the service time of battery of mouse.
The above embodiment, just better embodiment of the present utility model, be not limit the utility model practical range, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should comprise in the utility model patent claim.
