Description of the invention: [Technical field to which the invention pertains] In particular, it relates to a four-state steady state. The present invention relates to a constant force system constant force system. [Prior Art] The tractable mechanism can reduce the gap and friction of the rigid joints, the assembly process, and the cost reduction. ^ Particularly suitable for microelectromechanical systems (MEMS), especially MEMS. The process is still limited, and it is impossible to manufacture a rigid joint with good fit. The application of the flexible mechanism can improve the process yield and is widely used in MEMS. Taking a bistable microelectromechanical system 丨 as an example, referring to FIG. 1 and FIG. 2, a micro socket u, a micro connector 12, and a plurality of flexible elements η are included. The elbow 1 is not fixed at the fixed point and connected to the micro joint. Thereby, the flexible element 13 can interlock the micro-joint to the "first" steady state position separated from the micro-socket u and the second plugged into the micro-socket 11 without supplying energy. Steady position. Thereby, the bistable microelectromechanical system i is particularly suitable for use in a switching device 'capable of being in a steady state position without energy supply, not only having an energy saving effect' but also having a relatively high positioning accuracy with respect to a steady state position. However, the aforementioned bistable microelectromechanical system and system i have only two steady-state positions, and the MEMS technology that is increasingly complicated in operation cannot meet the requirements for use. SUMMARY OF THE INVENTION There are four steady-state bits. Therefore, it is an object of the present invention to provide a four-stable constant-force system. 201244019 __ Thus, the four-steering system of the present invention comprises an actuating element, a flexing element set. The actuating element is for transmitting - the active element set has at least one first flexible element acting on the actuating element, and at least - the second scoring element acting on the first flexible element, the first and second flexible The component is used to bear the aforementioned line shape of the Xianli production, so that the actuating element: springs in the range of the bounce, and a first critical value of the positive and negative forces, the second critical value and the third critical Value, output four steady-state ^ so that the actuating element maintains the original steady-state position without the influence of the front=spring range when the force does not exceed the aforementioned critical value, and can be 'stable' when the force exceeds the aforementioned critical value Three other steady-state positions outside the origin. The effect of the present invention is that when the force does not exceed the aforementioned critical value, it is maintained at a steady state position without being affected by the range of the front f-spring, and can be 'stable outside the origin when the force exceeds the aforementioned threshold value. The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 3, a preferred embodiment of the four-state steady force system of the present invention comprises an actuating member 3, a carrier 4, a pair of support members 5, and a flexible member group 6 for transmitting the actuating member 3. A force. This carrier 4 is used to mount the actuating element 3. The pair of floor members 5 are juxtaposed on both sides of the carrier 4 and are fixed at a fixed point. The flexible element group 6 has two first flexible elements 6i and two second flexible elements 201244019. The first flexible elements 61 are respectively carried by the carrier 4. The _楚_枝liL U,,,. The pair of support members 5 and the first flexible element 62 are suspended in the 哕哉_actuating member 3i, and are coupled to the carrier.

Referring to Fig. 3' and Fig. 5, when the HIM $ piece 3 stays at the origin two and: force..., the first flexible element ": two: 62 without any deformation, the strain generated The amount and the change sample are 〇, the force output by the actuating element 3 is 〇. ::, if the force F is gradually increased, and at the second='the first-flexible element (4) and the second flexible element Degree _^ Γ Γ ' and the degree of reversal of the first flexible element 61 is significantly greater than the second flexible actuating element ... ... a few pieces 62' see Figure 5, Figure 6, to the two When the party member is greater than the force F of the force, the first member 61 will have an irreversible deformation, causing the actuating member 3 to jump and stabilize at a second steady-state position that is out of the aforementioned bounce range. b, at this time 201244019 'The forces acting on these four-stable (four) force systems will quickly blame, and the strain energy of these four-stable constant-force systems is stable at a minimum. Thus, the effect of j Flmax can be regarded as For the 疋-th-threshold value, the four-stable (four) force system is stable to the second steady-state position, ie, point b, 'the first flexible element' and the first flexible 7C member 62 Total strain energy will remain at a minimum. The second flexible member 62 continues to be elastically deformed, and the second flexible member 62 continues to be elastically deformed between the force F and the F2max. Referring to FIG. 2, FIG. 7' to the actuating member 3, when the force is greater than the force F2, the second flexible element 62 generates an unrecoverable flute. The actuating element 3 jumps and stabilizes at a steady-state position that is out of the aforementioned bounce range. e. At this time, the forces of the four-stable (four) force system will quickly return to zero, and the strain energy of the four steady-state force systems is stable and extremely small. Thereby, the force f2_ can be regarded as a "second" or the like. The system is stabilized at the third steady state position. At this time, the total strain energy of the second tangible elements 62 held by the 疋 61 维 维 维 维 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 At this time, if the actuating element 3 is driven in the reverse direction and the force F does not exceed :::, the first flexible element 61 will continue to produce elastic deformation. See Figure 5, @8' to the action. When the component 3 is subjected to the I-shaped force F greater than the force, the first flexible component can be unrecoverable, and the actuating component 3 can be jumped to the fourth steady state position, that is, the point d. The forces subjected to these four-stable constant-force systems will quickly return to zero, while the strain energy of the steady-state constant-force system is stabilized at a minimum. Thereby, W can be regarded as a third critical value, and the four-stable constant-force system 201244019: stable "four-steady position, that is, point d, the first flexible element 61 J 4 second flexible element The total strain energy of 62 will be maintained at a minimum value. As can be seen from the above, the four steady-state force system of the present invention has the following advantages: the first critical value of the positive and negative forces F can be used. , the 帛L boundary value F2_ and the second critical value Fimax, change its steady position. Thereby, the actuating element #3 is not affected by the aforementioned bounce range when the force does not exceed the aforementioned threshold value. Steady-state position, and can be 'stabilized at four steady-state positions when the force exceeds the aforementioned critical value, and then meet the requirements of MEMS technology with multiple steady-states. ^ However, the above is only the comparison of the present invention.
