Abstract

The invention discloses a displacement amplifying mechanism which comprises a rigid rod body, of the two end parts are respectively a displacement input end and a displacement output end; a first spherical hinge part which is arranged on the rigid rod body, wherein the distance between the first spherical hinge part and the displacement output end is larger than the distance between the first spherical hinge part and the displacement input end; a supporting seat which is used for supporting the rigid rod body; and a second spherical hinge part arranged on the support; wherein the first spherical hinge part and the second spherical hinge part are connected in a matched mode to form a spherical hinge structure. The two-dimensional movement of the displacement input end of the rigid rod bodyenables the rigid rod body to rotate around the sphere center of the spherical hinge structure, so that the two-dimensional motion displacement of the displacement input end is amplified and then transmitted to the displacement output end of the rigid rod body, and a two-dimensional motion synchronous negative response is formed, so that a two-dimensional driving coaxial-response displacement amplifying mechanism is formed.

Description

technical field [0001] The invention relates to the technical field of displacement amplification, in particular to a displacement amplification mechanism, an optical fiber scanning device and a projector. Background technique [0002] The piezoelectric actuator is a new control and drive micro-drive based on the principle of fluctuations. It uses the inverse piezoelectric effect of piezoelectric elements to convert electrical energy into mechanical energy. Piezoelectric ceramic micro-displacement devices have the advantages of small size, large output, high resolution, and high frequency response. At the same time, they do not generate heat, have no noise, and are easy to control. They are ideal micro-displacement devices in nano-drive positioning technology. The widespread application of the mobile Internet has increased the application scenarios of mobile devices, and the miniaturization and light weight of mobile devices have become the development trend of mobile device...
