Problems solved by technology

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.
[0003] Some existing multi-stable mechanisms are partially flexible mechanisms, and the problems of assembly and friction still exist. Some fully flexible bistable mechanisms have a relatively small number of stable states, which cannot meet product needs.

Embodiment 1

[0024] figure 1 , figure 2 , image 3 and Figure 4 The description of the working state of the first embodiment of the present invention is given.

[0025] Such as figure 1 As shown, a method for realizing a fully flexible four-stable mechanism includes a flexible bistable mechanism 1 and a flexible fixed guide mechanism 2; the flexible bistable mechanism 1 is a bistable flexible mechanism. The flexible fixed guide mechanism 2 has a guide block 21, and the upper and lower ends of the guide block 21 are respectively connected with two groups of flexible beams, a total of four groups of flexible beams; each group of flexible beams includes the upper section 24 of the inclined flexible beam, the middle section of the inclined flexible beam 23 and the lower section 22 of the inclined flexible beam, the upper and lower two groups of flexible beams have the same shape, the upper section 24 of the inclined flexible beam and the lower section 22 of the inclined flexible beam hav...

Embodiment 2

[0031] Example 2 has the same structure as Example 1, but the initial state is different.

[0032] Such as Figure 5 As shown, the shuttle 11 of the flexible bistable mechanism 1 is in the lower initial position, and the upper ends of the two groups of flexible beams above the guide block 21 are connected with the shuttle 11 to form a figure 1 stable state in . also press Figure 6 , Figure 7 and Figure 8 direction, the other three stable states can be obtained.

[0033] Below we combine Figure 5 , Figure 6 , Figure 7 and Figure 8 The fully flexible tetrastable state constituted is further described.

[0034] When the guide block 21 is from the first stable equilibrium position ( Figure 5 The position of the middle guide block 21) moves to the right, the flexible beam of the flexible fixed guide mechanism 2 deforms and pushes the shuttle 11 of the flexible bistable mechanism 1 to move upward, and the shuttle 11 will jump to the second after passing through an un...

Abstract

The invention belongs to the field of compliant mechanisms and relates to a fully compliant tetra-stable mechanism and an implementation method thereof. The fully compliant tetra-stable mechanism comprises a compliant bistable mechanism and a compliant fixed guide mechanism, wherein the compliant bistable mechanism is a bistable compliant mechanism; the compliant fixed guide mechanism is provided with a guide block; the upper and lower ends of the guide block are respectively connected with two groups of compliant beams, totally four groups of compliant beams; the lower ends of the two groups of compliant beams at the lower end of the guide block are fixed and the upper ends of the two groups of compliant beams at the upper end of the guide block are connected with a shuttle of the compliant bistable mechanism. The implementation method of the tetra-stable mechanism is formed according to the fully compliant tetra-stable mechanism. The fully compliant tetra-stable mechanism has little energy consumption, simple structure, low cost, good stability and high repeatability precision and dispenses with external force or friction effect and assembly.

Description

technical field [0001] The invention belongs to the field of mechanical flexible mechanisms, and relates to a fully flexible four-stable mechanism and a method for realizing the four-stable mechanism, which can be used in products such as switches, valves, positioners, and reconfigurable equipment, and has low energy consumption, The structure is simple, the cost is low, and no assembly is required. 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. . [0003] Some existing multistable mechanisms are partially flexible mechanisms, and the problems of assembly and...
