Embodiment 1
[0025] The jump process of the bistable V-shaped mechanism has been disclosed in the domestic patent (publication number CN101834097). The mechanism has two local minimum potential energy points within the travel range. When the mechanism starts to deform from the first local potential energy minimum point, Convert the work done by the external force into deformation energy storage. When the deformation reaches a certain level, the stored deformation energy is released quickly, and the mechanism reaches the second local minimum point of potential energy to realize the bistable jump. Therefore, the present invention does not describe it in detail. describe.
[0026] figure 1 It is a tri-stable or quad-stable mechanism based on a cascaded bistable mechanism. The figure shows that the mechanism is in the first stable equilibrium state in the initial state, the upper bistable mechanism 1 is connected with the frame 3, and is threaded with the connecting rod 4 and the positioning ...
Embodiment 2
[0032] Figure 5 and Figure 6 A three-stable or four-stable mechanism with two sets of bistable cosine double-layer mechanisms is presented. On the basis of implementation 1, the upper bistable mechanism 1 and the lower bistable mechanism 2 adopt the upper cosine bistable mechanism 9 and the lower cosine bistable mechanism 10 respectively, relying on the relationship between the upper and lower cosine bistable mechanisms Interaction to realize tri-stable and four-stable functions, and by adjusting the relative position between the connecting rod 4 and the connecting groove 5 or the length of the connecting groove 5, the size of the stroke between each stable state and the distance between the strokes can be changed. The logical relationship is used to realize the adjustment of the steady-state position and the mutual conversion between the three-stable and four-stable functions. Figure 6 Between the connecting rod 4 and the connecting groove 5, the damping mechanism 11 is ...
Embodiment 3
[0034] Figure 7 A three-stable mechanism and a four-stable mechanism suitable for MEMS integrated processing are given. Relying on MEMS micromachining technology, the upper bistable mechanism 1, the lower bistable mechanism 2 and the frame 3 can be fixedly connected and connected at the same time. The rod 4 and the positioning rod 6 are fixedly connected with the upper mass block 7, and the connection groove 5 is fixedly connected with the lower mass block 7 to form an integrated mechanism, realize the overall processing of MEMS, and avoid cumbersome assembly process.
