Abstract
The invention discloses a wireless power charging and supplying type laptop. A wireless power charging and supplying mode is achieved through a magnetic resonance mode. according to the laptop, the complexity of power line connection during utilization of the laptop is eradicated, and the laptop is convenient and rapid to use.
Description
Technical field
The invention provides a kind of wireless charging for notebook computer, method of supplying power to, while having broken away from notebook computer use, connecting power line is loaded down with trivial details, more convenient to use, quick.
Background technology
Notebook computer is called again " portable computer ", and its maximum feature is exactly that volume is little, quality is light, is easy to carry.But use notebook computer all to need to plug loaded down with trivial details power lead at every turn, instead have PC to gently press power knob, just can not start shooting and come conveniently, unavoidably allow people think that some bothers, and power lead also can cause impaired possibility because of plugging frequently.
Idea by wireless way for transmitting electric power is not novel, but people focus on megawatt level (as solar energy collecting) or milliwatt level (as RFID) for a long time, how this technology is applied to the problem that has also become each large appliance manufacturers concern in various portable electronic equipments.
Summary of the invention
This patent has proposed a kind of wireless charging, power supply technique that is applicable to notebook computer, and the required electric energy of notebook is by electromagnetic transmission, thereby has saved the trouble of connecting power line and supply socket, is more convenient for the use of notebook computer.
The wireless charging of notebook computer, power supply technique have utilized magnetic resonance phenomenon, and its principle is the same with acoustic resonance, arrange the tuning fork that vibration frequency is identical, a sounding, other also can resonance sounding.Equally, be arranged in the coil of the identical vibration frequency in magnetic field, also can be by one to another power supply.Wireless charging, the power-supply unit of notebook computer are comprised of two parts: one is the transmitter being inserted on socket, and another is mounted in the receiver in notebook.The interior arrangement of transmitter and receiver can realize the copper coil of resonance, they have consistent resonance frequency, rely on resonance to carry out the transmission of energy, benefit is that energy loss is less, Propagation of Energy density is higher.
The inside of transmitter needs that the input of integrated DC power supply, frequency generating device, oscillatory circuit, shaping circuit, testing circuit, frequency interferences suppress that circuit, electric current are controlled automatically, wireless coil and capacitor resonance combination etc.Wherein frequency generating device is the vital part on transmitter.
Inner coil and capacitor resonance combination, rectifier, filtering and voltage stabilizer, the direct supply of integrating reception of needing of receiver exported.
For fear of transmitter, in the but situation of emitted energy of target of not charging, this patent has adopted active mode, when notebook computer is opened, sends and transmits code, and now transmitter just starts to corresponding notebook computer receiver power transmission.
In sum, the present invention has following technical characterstic:
2 have thoroughly broken away from the charge cable of notebook computer, have avoided the worry of looking for socket everywhere, connecing power lead, realize truly wireless
2 utilize magnetic resonance principle, have overcome distance and the position problems of way of electromagnetic induction
accompanying drawing explanation:
Fig. 1 is notebook computer wireless charging work schematic diagram
Transmitter is inserted in supply socket, and receiver is arranged in notebook computer, by magnetic resonance phenomenon generation current, is the required electric energy power supply of notebook.
Fig. 2 is notebook computer wireless charging schematic diagram
Send circle and be arranged in transmitter, receive circle and be arranged in notebook computer, first store the energy in transmitting terminal, the identical reception circle of resonant frequency near time, these energy will pass through resonance effects, and electric current is sent to receiving end, finally realize the radio transmission of electric power.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
- Wireless charging, for a notebook, it is characterized in that:Thoroughly break away from the charge cable of notebook computer, avoided the worry of looking for socket everywhere, connecing power lead, realized truly wireless.
