Embodiment 1

[0029] Such as figure 1 As shown, it includes at least the frame 1 and the flexible bistable mechanism 2 in the frame 1. The left and right ends of the flexible bistable mechanism 2 are fixed in the frame 1, and there is a first-stage connection parallel to the horizontal axis of the flexible bistable mechanism 2. Rod slider mechanism 3, the first stage linkage slider mechanism 3 includes a first stage guide rail 33, a first stage slider 31 and a first stage connecting rod 32, the first stage slider 31 is in the first stage guide rail 33, The first stage slider 31 and the shuttle 21 of the flexible bistable mechanism 2 are respectively connected to the first stage connecting rod 32 by a shaft; The position constitutes the first initial stable state. Through the position changes of the shuttle 21 and the first-stage slider 31, the flexible bistable mechanism 2 and the first-stage linkage slider mechanism form a four-stable mechanism. Its specific implementation or working sta...

Embodiment 2

[0034] Such as Figure 6 shown, with figure 1 The structure is different. In embodiment 2, there is a vertically fixed second-level guide rail 43 on the right (or left) of the first-level guide rail 33, and there is a second-level slider 41 inside the second-level guide rail 43. The second stage slide block 41 in the stage guide rail 43 and the first stage slide block 31 in the first stage guide rail 33 are respectively connected with the second stage connecting rod 42 by the shaft, so that the second stage slide block 41 is on the second stage guide rail 43 A position lower (or higher) than the horizontal axis of the first-stage slider 31 constitutes an initial stable state (first stable position) of the slider 41 . Also by the position changes of the shuttle 21 and the first stage slide block 31 and the position change of the second stage slide block 41, the flexible bistable mechanism 2, the first stage link slider mechanism and the second stage link slider mechanism form ...

Abstract

The invention belongs to the field of flexible mechanisms, relating to a multistable mechanism realizing method based on a single bistable mechanism and external characteristics thereof. A framework and a flexible bistable mechanism in the framework are comprised. The left end and the right end of the flexible bistable mechanism are fixed in the framework. The multistable mechanism realizing method is characterized in that connecting rod slide block mechanisms are in parallel to a horizontal axis of the flexible bistable mechanism; the connecting rod slide block mechanisms comprise lead rails, slide blocks and connecting rods; the slide blocks are in the lead rails; the lead rail of the next level of the connecting rod slide block mechanism is mutually vertical with the adjacent lead rail of the upper level of the connecting rod slide block mechanism; the connecting rod of the first-level connecting rod slide block mechanism is connected with a shuttle of the flexible bistable mechanism; and the last-level slide block is in the stable position of N=2M+1 through movement of the slide block in each level of the connecting rod slide block mechanism and the change of the upper position and the lower position of the shuttle of the flexible bistable mechanism, wherein M is the number of the connecting rod slide block mechanisms; and the minimum value of the M is 1. The invention depends on elastic potential energy stored in the flexible bistable mechanism to keep stable state, and does not need durative action of external forces.

Description

technical field [0001] The invention belongs to the field of flexible mechanisms, and relates to a multi-stable mechanism realization method based on a single bistable mechanism and its external characteristics. It has the characteristics of low energy consumption, simple structure, low cost, and low assembly cost, and can be used for switches , valves, relays and other products. Background technique [0002] Multistable mechanisms with multiple stable positions are commonly used in adaptive systems and some other fields. Traditional adaptive systems keep the system in the required stable position by applying external force or friction. The system that applies external force requires a lot of energy, and the system that uses friction will have losses, which will reduce the efficiency of the system and may eventually lead to system failure. . Therefore, there is a need for a mechanism that can remain in one or more stable positions without relying on external force or frict...
