Problems solved by technology
In the prior art, the power transmitting antenna usually adopts such as figure 1 The planar setting shown in the figure, due to the need for alignment, poses a large restriction on the placement of the power receiving end carrying the power receiving antenna, and the user experience is poor
Although some existing technologies improve the degree of freedom of the position of the power receiving end by setting multiple overlapping transmitting coils on a plane to form a power transmitting antenna, the degree of freedom of the position of the power receiving end is limited and cannot greatly improve the user experience.

A contactless power transmitting antenna and a power transmitting terminal are disclosed, by providing such that an axial face of the transmitting coil (referred to as a coil face) covers a side around the axial direction of the electric energy transmitting antenna, The magnetic field of the transmitting coil is uniformly distributed around the axial side of the electric energy transmitting antenna, so that the electric energy receiving end can be placed at any position in the circumferential direction of the electric energy transmitting antenna, a better coupling degree can be obtained, and the freedom degree of the position of the receiving coil is further improved.
Description
[0001] This application is a divisional application of a Chinese patent application with an application date of August 31, 2016, an application number of 201610796785.7, and an invention titled "Power Transmitting Antenna and Power Transmitting Device Using It". technical field [0002] The present invention relates to power electronics technology, and more specifically, to a power transmitting antenna and a power transmitting device using the same. Background technique [0003] Based on its convenient and practical features, the non-contact power supply technology is widely used in the field of electronic products, especially low-power consumer electronic products, such as mobile phones, MP3 players, digital cameras, portable computers, etc. Such as figure 1 As shown, taking the existing resonant non-contact power supply device as an example, it usually includes a resonant and magnetic coupling circuit composed of a power transmitting antenna and a power receiving antenna. ...
