Abstract
A frame (110) is rotatably coupled to a substrate (200) by way of a torsion spring element (100), wherein the frame (110) can be both twisted in relation to the substrate (200) and moved linearly in relation to said substrate (200). The torsion spring element (100) is made of a single piece and suitable for use in micro-electromechanical devices.
Claims6
A torsion spring element rotatably connected to a substrate and suitable for use in micro-electro-mechanical devices, wherein
- the torsion spring element can be twisted relative to the substrate, as well as moved linearly relative to the substrate;
- the torsion spring element is designed in one piece and comprises:
- a frame structure;
- an anchor structure preferably arranged within the frame structure;
- and
- spring structures connecting the anchor structure to the frame structure;
- the anchor structure connects the spring structures and the frame structure to the substrate;
- the frame structure, with deformation of the spring structures, moves as a whole relative to the anchor structure to produce rotational movements and linear movements of the torsion spring element relative to the substrate;
- and
- the spring structure has at least one pairing of two bending beam springs which extend from the anchor structure at an angle not equal to 0°, each have a kink, converge towards each other after the kink, meet at the frame structure, and are connected to the frame structure at that point.
