Stable state shutter structure.
Background technology
In recent years, the size of camera model develops with technology and reduces, but blade drive device size still restricts
The size of camera model, especially prominent in infrared camera industry.
More than infrared regime shutter, gear box combination is added using direct current generator at present and drive blade rotation, entered by spring
Row initial state shutter position is fixed, and its structure is as shown in figure 1, comprise motor 1, blade 2, focal plane 3 and support 4, motor 1
It is fixed on support 4, blade 2 is fixed on the axle of motor 1, blade 2 rotates under the drive of motor 1, blocks Jiao
Plane 3, thus realize the closing of light path；Motor 1 reversely rotates in the same manner, drives blade 2 to leave focal plane 3, realizes light path
Open.The direct current generator of this shutter structure size itself is larger, and especially length is longer, is easy to do with rear portion circuit board
Relate to, in addition spring structure increased the complexity of product, be unfavorable for product miniaturization, integrated development；The most critical issue is to adopt
Carry out initial state position with spring mechanism to fix, thus when leading to shutter closure, motor is constantly in locked rotor condition, affect motor
Service life, reduces the reliability of whole product.
Content of the invention
The technical problem to be solved be provide that a kind of size is little, long service life and reliability high for phase
The shock resistance bistable state shutter structure of machine module.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of shock resistance bistable state for camera model is fast
Door, including the magnetic valve with driving lever, support and blade, also includes balancing weight, described balancing weight and described fast gate flap
The end of piece is fixedly connected, and offers pulling hole on described balancing weight；Offer dialling along described magnetic valve on the bracket
The groove of the swaying direction of bar, the driving lever of described magnetic valve passes through described groove, and is inserted in described pulling hole；On described support
Position near described groove is fixedly installed rotating shaft, and described rotating shaft is each passed through described balancing weight and described blade, institute
State balancing weight and blade can together with around described axis of rotation, the entirety that described balancing weight and blade are fixed together
The barycenter of structure is located at the position that described rotating shaft is located.
The invention has the beneficial effects as follows：The present invention utilize magnetic valve bistable characteristic (magnetic valve driving lever has two in itself
Stable state, when driving lever is in stable state, under magnetic field force effect, holding position is fixed), shutter is opened and is respectively arranged with closure state
On two steady state points of magnetic valve, blade increases balancing weight simultaneously, and the barycenter of whole rotary part is adjusted to rotation
On axle, increased the impact resistance of shutter；Magnetic valve is semi-contact part, and loss ratio direct current generator and gear box combination are low,
And there is not stall problem, long service life, shutter reliability can be greatly increased.
On the basis of technique scheme, the present invention can also do following improvement.
Further it is contemplated that reducing the physical dimension of the present invention, described magnetic valve is miniature electromagnetic valve.
Further it is contemplated that avoiding the driving lever of magnetic valve balancing weight and blade when swinging to occur axially-movable to drop
The functional reliability of the low present invention, described rotating shaft offers draw-in groove away from one end axial direction of described support, in described draw-in groove
It is socketed with jump ring.
Further it is contemplated that lifting the balancing weight reliability fixing with blade, described balancing weight and blade one
Body formed or be bolted to connection.
Further it is contemplated that lifting the reliability that rotating shaft and support are fixed, described rotating shaft is integrally formed with support or passes through
Bolt is fixedly connected.

Specific embodiment
Below in conjunction with accompanying drawing, the principle of the present invention and feature are described, example is served only for explaining invention, not
For limiting the scope of invention.
As shown in Figures 2 and 3, a kind of shock resistance bistable state shutter structure for camera model, including the electricity with driving lever
Magnet valve 5, support 4 and blade 2, also include balancing weight 8, and balancing weight 8 is fixedly connected with the end of described blade 2, and
Pulling hole is offered on balancing weight 8；The groove of the swaying direction of driving lever along magnetic valve 5 is offered on support 4, magnetic valve 5
Driving lever passes through groove, and is inserted in pulling hole；On described support 4, the position near groove is fixedly installed rotating shaft 6,6 points of rotating shaft
Not Chuan Guo balancing weight 8 and blade 2, balancing weight 8 and blade 2 can together with rotate around rotating shaft 6, balancing weight 8 and shutter
The integrally-built barycenter that blade 2 is fixed together is located at the position that rotating shaft 6 is located.
Magnetic valve 5 is miniature electromagnetic valve 5, and rotating shaft 6 offers draw-in groove away from one end axial direction of support 4, in draw-in groove inner sleeve
It is connected to jump ring 7, the end of blade 2 is stacked together with balancing weight 8, and is bolted to connection, rotating shaft 6 and support 4
It is integrally formed.
Operation principle：
As shown in Figure 2 and Figure 4, shutter close now (i.e. blade 2 covers focal plane 3), magnetic valve 5 power-off is simultaneously located
In the first stable state, blade 2 and balancing weight 8 keep stable under the effect of magnetic valve 5 magnetic field force.Due to balancing weight 8 and shutter
The barycenter of blade 2 is located at rotating shaft 6, so now the driving lever institute stress of magnetic valve 5 is minimum, under thump, still can keep steady
State.Now such as need shutter to open, only need to lead to positive electricity, the driving lever rotate counterclockwise of magnetic valve 5 to magnetic valve 5, drive blade 2
6 rotation, reaches the second stable state the power-off of magnetic valve 5 around the shaft.
As shown in Figure 2 and Figure 5, shutter now is opened (i.e. blade 2 leaves focal plane 3), and magnetic valve 5 power-off is simultaneously located
In the second stable state, blade 2 and balancing weight 8 keep stable under the effect of magnetic valve 5 magnetic field force.Due to balancing weight 8 and shutter
The barycenter of blade 2 is located at rotating shaft 6, so now the driving lever institute stress of magnetic valve 5 is minimum, under thump, still can keep steady
State.Now such as need shutter to close, only need to lead to anti-electricity to magnetic valve 5, the driving lever of magnetic valve 5 turns clockwise, and drives blade 2
6 rotation, reaches the first stable state the power-off of magnetic valve 5 around the shaft.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
