| 摘要 |
An antenna rotation mechanism includes a bearing holder, a bearing, a first pressing member, a second pressing member, a plurality of first elastic arms and a plurality of second elastic arms. The bearing is disposed on an elastic fixing socket of the bearing holder. The first pressing member is disposed on first plane of the bearing and the second pressing member is disposed on second plane of the bearing. When the first pressing member abuts against the each first elastic arm along a first axial direction, the each first elastic arm provides a first radial thrust to the bearing, to force the bearing to move to an axle center. When the second pressing member abuts against the each second elastic arm along a second axial direction, the second first elastic arm provides a second radial thrust towards the bearing to force the bearing to move to the axle center. |

1. An antenna rotation mechanism, comprising:
a bearing holder; a bearing, disposed on an elastic fixing socket of the bearing holder; a first pressing member, disposed on a first plane of the bearing; a second pressing member, disposed on a second plane of the bearing; a plurality of first elastic arms, connected to the first pressing member, each of the first elastic arms being connected to the first pressing member, wherein when the first pressing member abuts against the each of the first elastic arms along a first axial direction, the each of the first elastic arms provides a first radial thrust force to the bearing, such that the bearing moves towards an axle center; and a plurality of second elastic arms, connected to the second pressing member, each of the second elastic arms being connected to the second pressing member, wherein when the second pressing member abuts against the each of the second elastic arms along a second axial direction, the each of the second elastic arms provides a second radial thrust force to the bearing, such that the bearing moves towards the axle center. |
