Abstract
The invention provides an annular array magnetic steel system and a magnetic attraction positioning system. The magnetic attraction positioning system comprises a first main body, a second main body and an annular array magnetic steel system, wherein the annular array magnetic steel system comprises a first magnetic ring with a first central axis and a second magnetic ring with a second central axis; the first magnetic ring comprises a first magnetic attraction unit arranged around the first central axis, the first magnetic attraction unit comprises first magnetic steel, second magnetic steel, third magnetic steel and fourth magnetic steel which are arranged around the first central axis and connected in sequence, and the magnetic pole directions of the first magnetic steel and the third magnetic steel are opposite and are arranged in the direction around the first central axis. The magnetic pole directions of the second magnetic steel and the fourth magnetic steel are opposite and the magnetic pole arrangement direction is parallel to the first central axis; the second magnetic ring comprises a second magnetic attraction unit, the second magnetic attraction unit comprises fifth magnetic steel, sixth magnetic steel, seventh magnetic steel and eighth magnetic steel which are in one-to-one correspondence with the first magnetic attraction unit. According to the scheme, the requirement for precise positioning can be better met.
Description
【Technical field】 [0001] The invention belongs to the technical field of magnetic suction positioning, and in particular relates to an annular array magnetic steel system and a magnetic suction positioning system. 【Background technique】 [0002] The magnetic alignment positioning system in wireless charging technology provides a strong enough magnetic attraction through the alignment between the magnetic steel accessories, and can automatically calibrate the eccentric position within a certain range, so that the device and the charging device are fully aligned to achieve the highest inductive Charging efficiency. However, in the related art, the magnetic attraction force, return area and magnetic shielding effect of the magnetic attraction alignment positioning system are not easy to balance, and there are often problems of insufficient magnetic attraction force, inappropriate return area and / or poor magnetic shielding effect, and it is not easy to release after positioning ...
