Abstract
The invention discloses a MEMS (Micro-electromechanical System) lever-type sheet-shaped interlocking mechanism, relating to a MENS structure and a precision positioning technology and belonging to the field of Micro-mechanics. The mechanism which is a sheet-shaped mechanism can move a slider under the condition of low accelerated speed, and the slider can be interlocked with a lever to realize accurate positioning when the slider moves to a preset position, moreover the interlocking between the slider and the lever is difficult to break under the action of a backward force. The MENS lever-type sheet-shaped interlocking mechanism consists of the slider, the lever and an external frame. When the slider moves to a right place under the action of centrifugal force, the slider is locked up by the matching of a clamp on the lever and a grooved on the slider, the slider can be positioned precisely and cannot spring back. All parts can be processed separately and then assembled according to a preset design, the implementation can be carried out simply, the lever and the external frame can be assembled together conveniently by using the semicircular clamp and the groove.
Description
Technical field
The present invention relates to a kind of MEMS (Micro-Electro-Mechanical System, MEMS) lever sheet mutual interlocking gear, belong to the micromechanics field.
Background technology
Along with the continuous development of society and and the continual renovation of technology, people improve constantly for the requirement of product, this makes that reducing its cost when product function is preeminent becomes the conflicting requirement that people must face.One of method that solves this difficult problem is exactly to adopt MEMS, be MEMS, it makes system and product develop towards miniaturization, intellectuality, integrated direction, can predict: MEMS can bring another time technological revolution to human society, it will exert far reaching influence to science and technology, the mode of production and the human being's production quality of 21 century, is to be related to national science and technology development, national defense safety and a key technology of prosperous economy.The characteristics of MEMS also are simultaneously that what to embody that its essential attribute requires is that device volume is little, in light weight, power consumption is low, inertia is little, resonant frequency is high, the response time is short, have only and have satisfied these conditions, just can better promote the development of manufacturing technology.
Deeply, various design philosophys cleverly continue to bring out China's research aspect the MEMS structural design in recent years gradually.The MEMS design key is a small size, high reliability, and low power consuming is easy to processing.General detent mechanism, slide block needs bigger initial moment, and when realizing the location, also consume very big energy: the limited space of MEMS structure except the movement environment of Lock-in (as Centrifugal Environment, fall environment) do not wish to provide again other power source as power resources yet, and reliability also has much room for improvement, so be badly in need of a kind of low energy consumption and detent mechanism that can accurately locate simple in structure.
Summary of the invention
The purpose of this invention is to provide a kind of MEMS lever sheet mutual interlocking gear, this mechanism can discern extraneous mechanical environment, and locatees accurately and reliably within a certain period of time.
MEMS lever sheet mutual interlocking gear is by slide block, and " lever ", outer rim is formed, and entire mechanism is a sheet mechanism.Each several part can be processed respectively, assembles according to design in advance then to get final product, and implements simple.
The major technique feature of MEMS lever sheet mutual interlocking gear of the present invention is: MEMS lever sheet mutual interlocking gear is by slide block, and " lever ", outer rim is formed.Be subjected to the slide block movement of the centrifugal action back that puts in place to carry out locking by the dop on " lever " and himself structural groove fit, slide block is precisely located and can resilience;
The object of the present invention is achieved like this: MEMS lever sheet mutual interlocking gear is by slide block, and " lever ", outer rim is formed.When this mechanism was subjected to centrifugal action, slide block was to the direction motion that deviates from pivot, and its front end is run into " lever " end, and " lever " other end dop slips into the interior locking of groove on the slide block, resilience that realization is precisely located and slide block can not break off relations.
The MEMS lever sheet mutual interlocking gear action principle and the course of work of super low energy consumption of the present invention are: slide block moves towards the direction that deviates from pivot under centrifugal action, behind the certain hour, its front end is run into " lever " end, " lever " other end is that dop is taken advantage of a situation and slipped into locking in the groove on the slide block, realizes precisely the resilience of can not breaking off relations of location and slide block; The centroid position of slide block is on mounting center O point right side.
Description of drawings
Fig. 1 is the overall construction drawing of mechanism
Fig. 2 is the structure chart of frame
Fig. 3 is " lever " structure chart
Fig. 4 is the structure chart of slide block
Wherein: 1-frame, 2-" lever ", 3-dop, 4-slide block, 5-slide block groove.
The specific embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the overall construction drawing of this mechanism, and in Fig. 1, framework 1 is fixing, and all the other structures can produce relative 1 motion.
Its assembling and annexation are as follows:
MEMS lever sheet mutual interlocking gear is by frame 1, and " lever " 2 and slide block 4 are formed, and its centroid position is on mounting center O point right side, and the slide block locking mechanism is finished jointly by dop 3 and slide block groove 5.Each several part is processed respectively, simple assembling.
The action principle of the present invention and the course of work are:
Is that the center is when rotatablely moving at MEMS lever sheet mutual interlocking gear with the O point, slide block 4 moves to the direction that deviates from pivot under action of centrifugal force, behind the certain hour, its front end is run into " lever " end, " lever " other end dop is taken advantage of a situation and is slipped into locking in the groove on the slide block, realizes precisely the resilience of can not breaking off relations of location and slide block.
