Problems solved by technology

[0005] At present, research on mechanical energy storage and rapid release on the microscopic scale and MEMS micro-impact hammers driven by low voltage is very limited. Among them, MEMS devices that can store and release μJ-level energy require too high a driving voltage, usually tens of Volts or even hundreds of volts to drive, so it cannot be widely used in practice

Abstract

The invention discloses a miniaturized impact hammer with low driving voltages. The miniaturized impact hammer is composed of such six portions: a cylindrical impacter, a beam for storing energy, a reduction gear set, a locking mechanism, a micro slider-crank mechanism and a comb-shaped driver. The beam and a spring body are used for storing energy, compared to a single locking structure, the reduction gear set is additionally arranged, a bull gear and a pinion gear are nested to each other, the pinion gear drives the bull gear, the reference circle radius of the pinion gear is r, the reference circle radius of the bull gear is R, and the driving force of the pinion gear is r / R of resistance of the bull gear. At the same time, under multistage gear set effects, the driving force of the pinion gear can be greatly reduced. According to the invention, through the effect of an electrostatic force, the comb-shaped driver is enabled to generate horizontal transverse displacement, through themicro slider-crank mechanism, the horizontal transverse displacement is converted into circumferential motion to drive the gear set to run so as to drive the hammer of the impacter to store and release the energy, the driving force is greatly reduced, and the energy is stored and released under the driving effects of small voltages.

Description

technical field [0001] The present invention relates to a micromechanical structure that can be widely used in jumping robots, needle-free delivery of drugs and vaccines, studying fracture on a microscopic scale, and designing a self-destructing sensor. Background technique [0002] Micro Electro Mechanical Systems (MEMS for short) is the broadening and extension of microelectronics technology. It is a system that integrates microelectronics technology and precision machining technology, and integrates microelectronics and machinery. Compared with macroscopic electromechanical devices, MEMS has the advantage of small size, and the thickness generally does not exceed 1cm. In addition, MEMS devices can be produced in large quantities and at low cost with a process compatible with integrated circuits, so the cost performance is greatly improved compared with traditional manufacturing technologies. MEMS technology is the most suitable technology for developing intelligent produ...
