Embodiment Construction

[0024] The present invention will be further explained below in conjunction with the accompanying drawings.

[0025] like figure 1 As shown, it is an embodiment of the present invention, the uniform power wireless power supply device comprises a cavity box body, the upper edge and the lower edge are provided with two parallel and symmetrical annular wireless power supply transmission coils 1 and 2, the two wireless power supply transmission coils 1 and 2. The coils have the same shape and size, and the uniform power wireless power supply area is located in the cylindrical cavity formed by the two wireless power transmission coils. In addition, one side wall of the box-type device is provided with a control system 3 for measuring, controlling and indicating functions.

[0026] In addition, two parallel transmitting coils are placed in the outer frame of the device. The double-ray coils can be coils of any shape, such as square, circular, etc. The distance between the two annul...

Abstract

The invention discloses a uniform-power wireless power unit, which is in box shape; the upper and lower edges of the box-shaped device are provided with two parallel, symmetrical and annular wireless power supply sending devices for providing a uniform magnetic field; one side wall of the box-shaped device is provided with a control system used for measuring, controlling and indicating, and comprising a control circuit, a driving circuit, a power circuit and an energy transmission loop; the control circuit generates a control signal and sends the control signal to the driving circuit which provides a driving signal for the power circuit according to the control signal; the power circuit provides electric energy with set power and frequency for the energy transmission loop according to the driving signal; and the energy transmission loop converts the electric energy into magnetic energy for sending. The uniform-power wireless power unit is simple in structure and efficient in performance and has better practicability.

Description

technical field [0001] The present invention relates to a wireless power supply device, in particular to a magnetically coupled wireless power supply device capable of transmitting uniform power. Background technique [0002] At present, wireless power supply technology has developed rapidly, especially the development of magnetically coupled wireless power supply devices. Many magnetically coupled wireless power supply devices have applied for patents, and low-power wireless power supply systems have been launched, especially The wireless power supply system for mobile phones began to be practical. However, most of the existing patents in this field are wireless power supply systems designed based on one transmitting and one receiving system, such as the existing wireless power supply system for mobile phones. The disadvantage is that in the power supply range of the power supply system, the received power is not uniform, that is, the power density is not evenly distribute...
