Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, Figure 2 and Figure 3, multifunctional notebook computer containment vessel comprises upper casing 9, drain pan 1.Wherein, upper casing 9 is made up of plastic material, when use, wrap up the appearance surface shell (back side of display screen) of notebook computer, inside comprises the planar inductor (primary coil of wireless power) 11 being connected with drain pan high-frequency inversion module 3, strong magnetic magnet 13 and upper casing power supply input interface 10.Drain pan 1 is made up of aluminum material, and the upper and lower surface of housing is distributed with louvre 8, is convenient to laptop heat-dissipation, is designed to wedge structure simultaneously, meets base of principle of human engineering; Drain pan 1 inside has comprised that poly-lithium battery 2(quality is little, thin thickness), notebook power supply output interface 7, upper casing power supply output interface 4, former limit high-frequency inversion module 3, functional switch 5, the internal battery charging inlet 6 of being powered by built-in poly-lithium battery.Multifunctional note containment vessel is placed in to notebook computer outside, and upper casing input interface 10 and the upper casing power supply output interface 4 of powering is connected.The material selection of containment vessel, will play a protective role gently as principle taking quality simultaneously, and therefore drain pan adopts aluminum material, and upper casing considers that aluminum is to producing magnetic shielding, disturbs wireless power function, therefore adopts plastic material.Integral product weight can be controlled in 500 grams.
The function of supplying power of notebook computer is realized: for popularity and the simplification of the use of increase equipment, without original notebook product is reequiped.When the powered battery that carries when computer is not enough; function of supplying power that can starting protection shell; the notebook power supply output interface 7 of containment vessel is inserted to the power hole of computer and can realize this function; this designs the prerequisite based on not changing original computer architecture; therefore containment vessel need be with power supply interface; when product has behind certain market; the shell that may change computer is manufactured rule; at the power positive cathode of computer base design computer; directly power by contact for containment vessel internal battery, now can remove the notebook power supply output interface 7 of containment vessel.
Wireless charging function is realized: need to charge to mobile phone time, only need open function switch, then mobile phone is placed in to the induction zone corresponding to upper casing of notebook-type computer protecting shell.Mobile phone wireless charge function with for notebook computer function of supplying power without conflicting, internal battery shell is supplied with computer power and the required electric energy of wireless charging simultaneously.
For mobile phone wireless charging, according to the state of notebook to there being two kinds of laying states:
(1) in notebook computer use procedure; directly mobile phone is invested to containment vessel upper casing (seeing accompanying drawing 2); both are fixed position by strong magnetic magnet 13; available small-sized magnet (ndfeb magnet) is realized: only need in notebook containment vessel, fix some magnet; in mobile phone shell, the magnet of fixing corresponding polarity, can realize both adhesives.
(2), in computer closed condition, now need the mobile phone of charging only need keep flat and be placed in upper casing and can realize charge function; Simultaneously because this technology adopts electromagnetic resonance formula wireless charging principle; long transmission distance is far above the wireless charging platform based on induction on the market; so mobile phone does not need to be close to containment vessel; allowing people to pick up mobile phone operates; upper casing wireless charging induction zone is not left in zone of action, has therefore greatly strengthened the practicality and the dirigibility that use.
High-frequency inversion modular circuit structure in containment vessel as shown in Figure 4; after open wireless charge switch; poly-lithium battery 2 in notebook Multi-functional protective shell is exported 12V direct current; supply high frequency inversion chip MC3306; circuit can be exported the frequency of two-way mutual symmetry from the extremely square wave of several million HZ frequencies of hundreds of KHZ; drive two metal-oxide-semiconductor IPD 160N04L to recommend output through L5101 again; electric capacity and coil inductance through overmatching form resonant circuit; resonance frequency is identical with output square wave frequency, realizes the transmitting of electric energy.
Wireless energy receiving circuit is positioned at mobile phone 12; the resonance frequency of secondary coil is consistent with the primary coil resonance frequency in containment vessel; by resonance, delivery of electrical energy is arrived to secondary; after overcommutation, filtering, voltage stabilizing, be charging mobile phone battery again, thereby realized the wireless charging function of computer protection shell.Described radio energy receiver module belongs to more easily realizes part, does not do further investigated in the utility model, and voltage stabilizing chip can adopt LM2596, and commutation diode can adopt high-frequency diode IN41418 or IN5819.
In the time that the built-in battery capacity of notebook-type computer protecting shell is low, need charge to the built-in poly-lithium battery 2 of containment vessel, now use supporting power supply adaptor, by internal battery charging inlet 6, access power frequency civil power can charge to battery.
Can open as required or close wireless charging function by functional switch 5, close this function after the former limit of wireless charging will stop consuming electric energy, reach as required use, the object of green energy conservation.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection domain of the present utility model.
