Abstract

The utility model discloses a wireless charging device, including a power supply module, an RF emission module, a button, a charging module, an RF reception module and a display module. The power supply module and the button are respectively connected with the RF emission module; the charging module and the display module are respectively connected with the RF reception module; and the RF emission module and the RF reception module employ omnidirectional antennas. In the utility model, the scheme of omnidirectional wireless microwave electric energy transmission is employed, the problem is solved that the electromagnetic radiation in the prior art is strong, bidirectional communication and bidirectional identification between the emission terminal and the reception terminal are realized, and the technology problem is solved when a plurality of wireless devices are charged simultaneously.

Description

Wireless charging device

Technical field

The utility model relates to a kind of wireless charging device, relates in particular to a kind of discernible wireless charging device.

Background technology

Many wireless charging devices occurred on the market now, can mobile device have been charged such as mobile phone, PDA, digital camera, MP3, notebook computer etc.When charging, often to be placed on the appointed area to single power consumption equipment and just can charge, if the residing position of power consumption equipment exceeds the scope of its regulation, charging effect is just very poor.The big limitations of this directive property the popularization of wireless charging device on market.Secondly, the electromagnetic radiation intensity of this charging device is very big, and directive property is very strong, and when a plurality of mobile devices need charge, this charging modes can't cause its charge efficiency not high to its whole chargings.

Summary of the invention

The purpose of the utility model is to provide a kind of wireless charging device, solves the big problem of prior art electromagnetic radiation intensity, solves the problem that a plurality of wireless devices can't charge simultaneously.

The purpose of

the utility model is achieved through following technical scheme:

A kind of wireless charging device; Comprise supply module 1, RF transmitter module 2, button 3, charging module 4, RF receiver module 5, display module 6; Said supply module 1, button 3 link to each other with RF transmitter module 2 respectively; Said charging module 4, display module 6 link to each other with RF receiver module 5 respectively, and said RF transmitter module 2, RF receiver module 5 adopt omnidirectional antennas.

Compared with prior art; The beneficial effect of the utility model is: adopt the scheme of the wireless microwave transmission electric energy of omnirange, solve the big problem of prior art electromagnetic radiation intensity, realize the two-way communication of transmitting terminal and receiving terminal; Bidirectional recognition solves the technical problem that a plurality of wireless devices charge simultaneously.

Description of drawings

Fig. 1 is the structural representation of wireless charging device transmitter module;

Fig. 2 is the structural representation of wireless charging device receiver module.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.As shown in Figure 1; The utility model transmitter module comprises supply module 1, RF transmitter module 2, button 3; As shown in Figure 2, the utility model receiver module comprises charging module 4, RF receiver module 5, display module 6, and said supply module 1, button 3 link to each other with RF transmitter module 2 respectively; Said charging module 4, display module 6 link to each other with RF receiver module 5 respectively, and said RF transmitter module 2, RF receiver module 5 adopt omnidirectional antennas.Supply module 1 provides required electric energy by alternating current, and supply module 1 is after over commutation, filtering, voltage stabilizing, for RF transmitter module 2 provides required reference power supply.Button 3 is connected through the I/O mouth with RF transmitter module 2, when matching with receiver module, uses the authority that is used to distribute charging device.Authority distributing method is following: transmitter module is outwards launched wireless signal; Receiving equipment is received return address information behind the signal; Transmitter module is preserved the relevant information of each equipment; Near receiver module, push button 3 with transmitter module this moment, and at this moment receiver module and transmitter module have just bound together.The pairing process of Here it is wireless charging device, the equipment of being bound just can and transmitter module between carried out wireless charging, the authority that then is not recharged of the equipment of binding not.The antenna of receiver module is received the microwave electric power signal that transmitter module sends; Give charging module 4 through RF receiver module 5 with electric energy transmitting; Charging module 4 is made up of rechargeable battery; Be used for storage of electrical energy. meanwhile, RF receiver module 5 shows charged state through display module 6, is convenient to client in real time monitoring correlation energy transmission situation.RF receiver module 5 and real-time voltage and current state to RF transmitter module 2 feedback rechargeable batteries are used under the state of emergency, taking measures, and prevent power consumption equipment is damaged.

The utility model adopts the scheme of the wireless microwave transmission electric energy of omnirange, solves the big problem of prior art electromagnetic radiation intensity, realizes the two-way communication of transmitting terminal and receiving terminal, and bidirectional recognition solves the technical problem that a plurality of wireless devices charge simultaneously.The charged state of power consumption equipment can feed back to transmitting terminal through wireless signal, and transmitting terminal is made judgement according to the voltage and the change in current of receiving terminal battery to charged state, in time turn-offs the launched microwave signal.When not having charging or charging end, the transmitting terminal power consumption is very little, low power consumption standby.The bidirectional recognition function of transmitting terminal and receiving terminal can be discerned the receiving terminal of metal object and unbundling, and this moment, transmitting terminal can not get into emission state.When the battery temperature of receiver module surpassed the temperature of systemic presupposition, transmitting terminal stopped emission work immediately.When the battery terminal voltage of receiver module and electric current surpassed the state of system's regulation, transmitting terminal also can stop emission work immediately.

Except that the foregoing description, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
