Embodiment
Be depicted as the bistable state mechano-electronic shutter of an embodiment of the utility model like Fig. 1,2,4, comprise: inner disc 1, its central authorities are provided with first through hole 11 that forms aperture; The slip ring 2 that is installed in inner disc 1 first end face and can on inner disc 1, slides; Be connected with slip ring 2 and drive the bistable state driving mechanism 3 that slip ring 2 slides on inner disc 1; Be installed on the second opposing end face of inner disc 1 said first end face and a plurality of blades 4 that are connected with said slip ring 2, it is used to cover or opens said first through hole 11; Be installed in the circuit control unit 5 of inner disc 1 said first end face and control bistable state driving mechanism 3 forwards (being CW shown in Figure 4) or reverse (being counter clockwise direction shown in Figure 4) motion.
Wherein, bistable state driving mechanism 3 only needs circuit control unit 5 to provide the power supply of 12V to get final product work, and work rear drive slip ring 2 slides on inner disc 1, slides thereby drive the blade 4 that is connected with slip ring thereupon.Bistable state driving mechanism 3 only opens and closes moment at shutter needs the power supply power supply; All the other times do not need the power supply power supply; Therefore this bistable state mechano-electronic shutter does not have power consumption at the burn-out time durations, so do not generate heat, does not have electromagnetic effect; Reduce electromagnetic interference (EMI) greatly, effectively prolonged the serviceable life of this shutter miscellaneous equipment.And slip ring 2 is installed in the opposing end face of inner disc 1 respectively with blade 4, so can not interfere with each other at bistable state mechano-electronic shutter duration of work slip ring 2 and blade 4, has guaranteed shutter reliability in the course of the work.Below the structure of bistable state mechano-electronic shutter is elaborated.
Like Fig. 3,4, shown in 5; Inner disc 1 is the primary element that is assembling other bistable state mechano-electronic shutter components and parts; It is a disk, at its first end face slip ring 2, bistable state driving mechanism 3 and circuit control unit 5 is installed, and with the second opposing end face of first end face a plurality of blades 4 is being installed.Concrete, be provided with annular groove 12 at first end face of inner disc 1, and slip ring 2 is installed in 12 li of this annular grooves, can be annular groove 12 in when slip ring 2 receives thrust or tension along clockwise or slip counterclockwise.And blade 4 be installed in opposing second end face of inner disc 1 first end face on; Like Fig. 5,6, shown in 8; On 12 li of the annular grooves of slip ring 2, inner disc 1 and blade 4, be respectively equipped with the corresponding third through-hole in a plurality of positions 21, second through hole 13 and fourth hole 41; And bearing pin 8 passes the opposing end face that above-mentioned three through holes are separately fixed at slip ring 2 and blade 4 inner disc 1 successively; Thereby make blade 4 be located at first through hole 11 inner disc 1 central part, that can form aperture along with slip ring 2 covers or opens in the slip of 12 li of annular grooves, the control shutter does not make public or makes public.And in order to realize that slip ring 2 can be in 12 li slips of annular groove after stressed; When design; Should make second through hole 13 along the size of circumferential size, thereby make slip ring 2 and blade 4 in motion process, can be in the diverse location of second through hole 13 greater than third through-hole 21 and fourth hole 41.And in the utility model blade 4 and slip ring 2 be installed in the opposing end face of inner disc 1 respectively; In the time of can solving the fast goalkeeper's blade 4 of tradition and slip ring 2 and be installed in the same end face of inner disc 1 simultaneously, blade 4 runs improperly with slip ring 2 and lives, occurs the phenomenon that the tight or slide plate of blade closure and blade run foul of each other in the shutter course of work.
In order to make the slip ring 2 can be in 12 li slips of annular groove; As shown in Figure 4, also be equipped with at first end face of inner disc 1 and drive the bistable state driving mechanism 3 that slip ring 2 slides and be connected through circuit with bistable state driving mechanism 3 and the circuit control unit 5 of the energy be provided for it.Wherein, Circuit control unit 5 can be exported forward voltage or reverse voltage; Make the bistable state driving mechanism 3 that connects through circuit with it can realize motion forward or backwards; And the open and close that bistable state driving mechanism 3 carries out shutter in order to drive vane 4 are moved, and stablizing under two states opened and closed to the assurance shutter, so both cooperatings can be guaranteed the work that bistable state mechano-electronic shutter can be normal and stable.When design circuit control module 5, make full use of the space of shutter; Effectively dwindle the area of circuit board, adopt to be fan-shaped circuit board, thereby circuit control unit 5 is integrated into the inside of shutter; Need not adopt extra external control circuit, therefore use convenient.
The circuit control unit 5 of the utility model can adopt any circuit structure that bi-directional voltage is provided, and such as adopting simple bi-directional voltage change-over switch, perhaps adopts the voltage commutation circuit that has processor and photoelectric coupled device.
When circuit control unit 5 provides a forward voltage; Generation can make the magnetic force that slide-bar 32 moves along CW shown in Figure 4 in the electromagnetic driver 31; Thereby the driving contiguous block 33 that promotes to be fixedly connected with an end of slide-bar 32 reaches the driving brace 34 that is rotationally connected with driving contiguous block 33 and also moves along clockwise direction; Slip ring 2 CWs that promptly promote to be connected with driving brace 34 move to a place, position of second through hole 13 on the inner disc 1; And then drive blade 4 and open first through hole 11, i.e. shutter opening, and when shutter opening after as if do not receive external force then slip ring 2 can be fixed on a place, position motionless always.And when circuit control unit 5 provides a reverse voltage; Generation can make the magnetic force that slide-bar 32 moves along counter clockwise direction shown in Figure 4 in the electromagnetic driver 31; Thereby pulling slide-bar 32 and driving contiguous block 33, driving brace 34 are also along counterclockwise moving; Promptly and pulling slip ring 2 moves to the b place, position of second through hole 13 counterclockwise, and then drive blade 4 covers first through hole 11, i.e. shutter close.
In order better to indicate the state of shutter open and close; The bistable state mechano-electronic shutter of the utility model also comprises opening or closing and export the photosensitive control unit 35 of high pressure or low-voltage signal with blade 4 in bistable state driving mechanism 3; As shown in Figure 7; It comprises: with drive that contiguous block 33 is fixedly connected and the feedback signal indicator 351 of exportable high pressure or low-voltage signal, the one of which end is provided with a photographic hole 351a; Be fixed on the inner disc 1 with the optoelectronic switch that covers or expose conducting or not conducting 352 of said photographic hole 351a, it is connected through circuit respectively with electromagnetic driver 31 with feedback signal indicator 351.When driving contiguous block 33 moves along CW shown in Figure 4; Feedback signal indicator 351 also thereupon CW move; When the photographic hole 351a of one of which end is covered by optoelectronic switch 352; Optoelectronic switch 352 is switched on, feedback signal indicator 351 output HIGH voltage signals, and the expression shutter is opened; Otherwise, then optoelectronic switch 352 not conductings, feedback signal indicator 351 output LOW voltage signals, expression shutter close.
In addition, bonnet 6 is installed, shell 7 is installed at second end face at first end face of inner disc 1.The bistable state mechano-electronic shutter of the utility model can adopt corresponding product or the parts that king's electronics workbench is produced in Beijing.
Although preceding text have been done detailed description to the utility model; But the utility model is not limited thereto; The technician in present technique field can make amendment according to the principle of the utility model; Therefore, all various modifications of carrying out according to the principle of the utility model all are to be understood that to falling into the protection domain of the utility model.
