Conversion braking structure for power and mechanical energy

Abstract

The invention relates to an electrical energy mechanical energy transformation beaking structure, it contains an electrical energy braking unit, the one end surface of electrical energy braking unit firmly locates on a base, another end surface joint with an elastic transmission module, the elastic transmission module extends an elastic section to the electrical energy braking unit outside, this elastic section because of the elastic transmission module reciprocation moves has the oscillation amplitude, a conduction department set on the elastic section, this conduction department has bigger friction coefficient, Again a passive module setup in the conduction department, the conduction department exerts the pressure with the passive module by an elastic module to become the friction joint, enables the passive module to make the axial friction drive in the conduction department; when moves by the above structure in elastic transmission module produces oscillation amplitude, can enlarge the passive module displacement quantity, then enhances the passive module travelling speed and reduces the operating frequency of the drive pulse wave.

Description

technical field [0001] The present invention relates to an electric-mechanical-energy conversion actuation structure, in particular to an electric-energy actuator to produce a displacement action, which is converted by a mechanical structure such as an elastic transmission component, which can produce a displacement-extending effect after the conversion, thereby improving passive motion. Components move faster and reduce the operating frequency of the driving pulse, which is used for actuators in precision instruments, such as the movement of lenses or image sensors in portable electronic products with photography or camera functions. Background technique [0002] In US Patent No. 6,218,764, an actuator using an electromechanical transducer capable of driving efficiently and at high speed is provided. It mainly fixes a first component on one end of an electromechanical transducer, and another fixed second component is frictionally combined with the first component, and the f...

AI Technical Summary

Problems solved by technology

[0004] The reliability of the structure will be reduced due to the inability to make a rigid connection between the actuator and the drive shaft

[0005] Because the displacement of the piezoelectric element is directly used, its displacement is too low, so that the operating frequency of the piezoelectric actuator cannot be further reduced

[0006] The waveform used in this example has high-frequency harmonic components, resulting in an increase in leakage current

[0007] Clearance must be maintained between the actuator and the transmission rod to avoid affecting movement, resulting in wasted space and cannot be further miniaturized

[0008] The displacement and output force of piezoelectric actuators are too low, which is easily affected by load changes

[0009] Clearly, known technology leaves room for improvement
