Magnetic levitation support

Abstract

This novel magnetic levitation bracket includes a back plate with an indented outer mounting groove on its outer side; a plurality of inner magnets arranged around the inner side of the back plate, each inner magnet having a magnetic dissimilarity to its two adjacent inner magnets; a base, which is annular and rotatably disposed in the outer mounting groove; at least one outer magnet disposed on the side of the base facing the back plate, the position of the at least one outer magnet corresponding to the position of each inner magnet; and a support plate pivotally mounted on the base. When the back plate is mounted on a handheld electronic device, the user can pivot the support plate out and rotate the base to adjust it to an appropriate angle, so that the handheld electronic device can stand upright on one side, providing the user with a comfortable viewing angle. The magnetic levitation rotating mechanism can improve the feel during rotation and reduce wear and tear, thus extending the service life.

Claims

1. A magnetic levitation support, comprising: a back plate having an inner side and an outer side facing each other, the outer side being recessed to form an outer mounting groove; a plurality of inner magnets disposed around the inner side, each inner magnet having a magnetic dissimilarity to its two adjacent inner magnets; a base being annular and rotatably disposed in the outer mounting groove; at least one outer magnet disposed on a side of the base facing the back plate, the position of the at least one outer magnet corresponding to the position of each of the inner magnets; and a support plate pivotally mounted on the base; wherein... When the at least one outer magnet rotates to the position of one of the inner magnets with the same magnetic properties, the base is in a magnetic levitation state; when the at least one outer magnet rotates to the position of one of the inner magnets with different magnetic properties, the base is magnetically attracted to the back plate.

2. The magnetic levitation support as described in claim 1, wherein the base has at least one fixing groove recessed on one side facing the back plate, and the at least one external magnet is disposed in the at least one fixing groove.

3. The magnetic levitation support as described in claim 2, wherein the number of the at least one fixing slot is multiple, the number of the at least one outer magnet is multiple, and the fixing slots are arranged in a circumferential interval and correspond to the positions of the inner magnets.

4. The magnetic levitation support as described in claim 3, wherein each of the fixing slots is arranged at equal intervals, and the width of each interval is approximately equal to the width of each of the inner magnets.

5. The magnetic levitation support as described in claim 1, wherein a limiting groove is formed on the wall of the outer mounting groove near the bottom end, the limiting groove being recessed around the wall of the groove, and the base is formed with an annular protrusion, the annular protrusion being circumferentially protruding from the outer annular surface of the base, the annular protrusion extending into the limiting groove.

6. The magnetic levitation support as described in claim 1, wherein the inner side of the back plate is recessed to form a plurality of inner mounting slots, the inner mounting slots being arranged in a circumferentially spaced manner, and each inner magnet being disposed in each inner mounting slot.

7. The magnetic levitation support as described in claim 3, wherein each inner magnet has inner and outer sides, the inner magnetic poles being different from the outer magnetic poles, and each outer magnet has inner and outer sides, the inner magnetic poles being different from the outer magnetic poles.
