Abstract

The utility model discloses a wireless charging desk which comprises a desktop and a wireless charger, wherein the wireless charger is connected with an external power source by a conducting wire and a plug.

Description

The wireless charging table

Technical field

The utility model belongs to a kind of charging device, particularly, is a kind of wireless charging table that utilizes the electromagnetic induction technology for the terminal electronic equipment charge.

Background technology

Wireless charging is not meant just can transmit electric energy through physical connection, is embodied as the purpose of the less relatively electronic product charging of power consumption such as mobile phone, MP3, bluetooth earphone.At present, realize wireless charging mainly through three kinds of modes, i.e. electromagnetic induction, radio wave and resonance effect, wherein electromagnetic induction the most commonly through the coil-induced generation electric current of primary and secondary, thereby is transferred to receiving terminal with energy from transmission ends.

Yet traditional charging method need be used charger, socket, perhaps comes to be the terminal electronic equipment charge through data wire; The user is often because leave behind charger or data wire; Perhaps do not have socket and can't be in time be the terminal electronic equipment charge, brought very big inconvenience to the user, in addition; Because the cause of terminal electronic equipment brand, model; Terminal electronic equipment needs and charger or the supporting use of data wire, and charger or data wire can not be accomplished the charging process to a plurality of terminal devices, like mobile phone, notebook, digital camera etc.

The utility model content

The purpose of the utility model is to overcome the deficiency of prior art, and a kind of wireless charging table with wireless charging function is provided.

For achieving the above object, the wireless charging table that the utility model provided comprises desktop, wireless charger, and said wireless charger is connected external power supply through lead with plug.

The remarkable result of the utility model is: increased wireless charger at the normal domestic use desk or on handling official business with table; When the user need be to the terminal electronic equipment charge; Only need terminal electronic equipment is placed on the induction zone on the desktop, can accomplish charging process, solved the user because of leaving behind charger or data wire to terminal electronic equipment; Perhaps do not have socket and can't in time be the difficult problem of terminal electronic equipment charge, make charging process simple more, convenient; Simultaneously; Because wireless charger has the full function of closing automatically of electricity; Avoided unnecessary energy consumption, solved existing charger because of overcharging the potential safety hazard that produces, in addition; Wireless charger can charge to a plurality of terminal electronic equipment simultaneously simultaneously, has brought very big facility for people's daily life, work.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.

Embodiment 1: Fig. 1, shown in 2, and a kind of wireless charging table comprises desktop 1; Also comprise wireless charger 2, said wireless charger 2 is connected external power supply through lead 3 with plug 4, and on desktop 1, forms induction zone 5; Wherein, lead 3 links to each other with wireless charger 2 interior transmission coils, when plug 4 inserts external receptacle; External power supply is the transmission coil power supply in the wireless charger 2 through lead; Transmission coil in the wireless charger 2 produces induced field, and when terminal electronic equipment placed the induction zone 5 on the desktop 1, the receiving coil in the terminal electronic equipment was sensed and sent the induced field that coil produces; Produce electric current, it is the battery charge in the terminal electronic equipment that the electric current of generation is handled the back through step-down rectifying circuit.

Embodiment 2: like Fig. 3, shown in 4, a kind of wireless charging table comprises desktop 1; Also comprise wireless charger 2; Said wireless charger 2 is connected external power supply through lead 3 with plug 4, and wherein external power supply adopts alternating current, and the electric current that flows through in the wireless charger 2 changes; Produce radio wave; Radio wave is sent to the conductor of terminal electronic equipment through air, and the electromagnetic field that radio wave causes changes and in the conductor of receiving terminal, produces electric current again, and it is the battery charge in the terminal electronic equipment that the electric current of generation is handled the back through step-down rectifying circuit.

Claims

1. a wireless charging table comprises desktop (1), it is characterized in that: also comprise wireless charger (2), said wireless charger (2) is connected external power supply through lead (3) with plug (4).
