Description
Technical field
The utility model relates to a kind of Wireless Keyboard utilizing super capacitor to realize solar recharging and hypervelocity charging.
Background technology
Solar cell is very ripe, and cost is not high yet, and in a lot of Low Power Consumption Portable equipment, application prospect is extensive.But is not a lot of at present in consumer electronics product.Such as intelligent watch, telepilot, keyboard etc. do not use solar cell on a large scale.This is because solar energy density ratio is lower, so the output voltage of small-sized solar battery, electric current are very little.And along with the change of luminous environment, its voltage, curent change scope are very large, and general electronic system and battery all need metastable electric current and voltage could normal work.For common rechargeable lithium battary, charging voltage is also generally need constant voltage and just can charge normal (this electric current is generally greater than the electric current that small-sized solar battery produces) higher than the electric current of certain threshold values.In order to output voltage and the electric current of constant solar cell, its circuit cost is higher than solar cell, and the cost performance of system is very low.So a lot of portable electric appts does not generally use small-sized solar battery at present.
Super capacitor more and more receives the concern of people as a kind of emerging means of energy storage, its feature clearly: environmental protection, hypervelocity charging, life-span are long, non-maintaining.The medium that automobile at present in a lot of public transport is also using super capacitor to make power storage.Electric capacity has an extraordinary characteristic, and that is exactly do not have threshold values to limit when charging, and no matter how many electric currents can directly charge, as long as and voltage lower than the withstand voltage of electric capacity, the fluctuation for voltage, electric current does not also limit.
There are many Wireless Keyboards being communication modes with BLE (abbreviation of Bluetooth Low Energy version) at present on the market, have employed the same computer of communication modes of BLE, Pad even mobile communication, realize the function of Wireless Keyboard input, but this Wireless Keyboard often uses tradition No. 7 batteries, and service time neither be very long; Dead battery capability needs to change battery; There is no hypervelocity charge function.
Utility model content
In order to solve the problems referred to above that prior art exists, the utility model proposes a kind of Wireless Keyboard utilizing super capacitor to realize solar recharging and hypervelocity charging, for existing market Wireless Keyboard Problems existing, realized solar recharging and the hypervelocity charge function of Wireless Keyboard by introducing super capacitor and flexible solar battery.
For achieving the above object, the utility model is solved by following technical scheme:
A kind of Wireless Keyboard utilizing super capacitor to realize solar recharging and hypervelocity charging of the present utility model, comprise housing, low power consumption control device in housing, the push-button array be connected with this low power consumption control device communication, also comprise solar cell, this solar cell passes into described low power consumption control device through current limiting pressure-limiting circuit, super capacitor after converting the luminous energy of collection to electric energy successively, and this low power consumption control device carries out communication by antenna and main frame; One external charger is connected with described current limiting pressure-limiting circuit.
Wireless Keyboard described in the utility model, described super capacitor connects described low power consumption control device by a current-limiting circuit.
Wireless Keyboard described in the utility model, described external charger is that output voltage is more than or equal to 5V, and output current is greater than the charger of 0.5A.
Wireless Keyboard described in the utility model, described solar cell is flexible solar film, and it is fitted in described surface of shell.
Wireless Keyboard described in the utility model, described super capacitor is withstand voltage more than 5V, capacity is greater than 1F.
Owing to adopting above technical scheme, compared with prior art, the scheme that the utility model adopts super capacitor to add solar cell has following advantage than existing simple battery powered Wireless Keyboard:
1. environmental protection: the super capacitor life-span is very long, does not almost have the restriction of charging times, therefore need not replace in the product life cycle.Electric capacity itself is also environment-friendly materials manufacture, so have huge advantage for environmental protection.
2. solar recharging: the bottleneck problem of sun power to battery charging application is trickle charge, by just directly solving the problem of trickle charge with the direct substituting battery of super capacitor, and greatly reduces system cost; Owing to adopting solar recharging, when normal indoor light, need charging hardly, even if because weather or other factors cause charging, also can solve use problem with hypervelocity charging.
3. hypervelocity charging: electric capacity inherently has the characteristic of hypervelocity charging, and such as, the super capacitor of 1 1F just can be full of for 2.5 seconds when 2A electric current, 5V, and the super capacitor of 4F just can be full of for 10 seconds when identical charging current and voltage.Use conventional DC voltage to be more than or equal to 5V, the charger that output current is greater than 0.5A just can realize hypervelocity charging, and this is the change of matter for Consumer's Experience.
