Abstract
The utility model relates to a bistable electric magnet for a mechanical locking device of a system, which is generally used for a computer lock or other devices which need to work according to a locking and unlocking mode. Compared with the existing product having similar functions, the utility model is characterized in that a permanent magnet is additionally arranged in a magnetic conductive loop, and the utility model has a self-hold function when a device in the attracting state; consequently, pulse current can pass the device at the instant moment of the change of the opening state and the close state, and the device does not need to be energized in any holding process; consequently, the utility model is extremely energy-saving and improves the over-all performance of a complete machine.
Description
Affiliated technical field:
The utility model relates to the electric operator on the battery powered motor machine locking device (particularly room with computer or electronic lock).
Background technology:
Existing computer lock, the general electromagnet that adopt of the topworks of system comprise three kinds of structures of horizontal, disc type and vertical type the design of adopting direct current generator to drive worm mechanism also being arranged more, they all are to adopt dry cell power supply.In order to guarantee long-term, the effectively work of total system, the high reliability of topworks and super low-power consumption have become the main restricting factor of product quality.In order to handle this problem, the electromagnet in the existing computer lock had adopted maintenance process behind the big current start of moment (as about 0.3 second) to adopt the mode of less electric current operation already, in the hope of reaching power savings.And when reducing startup and holding current, must weaken the elastic force of back-moving spring, this has reduced the stability and the reliability of system to a certain extent.Also should be emphasized that: for the system that adopts dry cell power supply, even the method for operation that has adopted " little electric current " to keep, expending of electric energy still can not be satisfactory.
Summary of the invention:
The purpose of this utility model provides a kind of improvement project that locks with electromagnet, and the stability that can strengthen inhaling, putting two states can cut down the consumption of energy on the other hand significantly on the one hand, to guarantee complete machine running for a long time and reliably.
The technical scheme that the utility model adopted is: 1, install the annular permanent-magnet body that posts magnetic conductive iron sheet additional in the right-hand member inboard of magnetic conduction support, the moving iron core (sheet) that makes it and implement locking effect is on the same axis, and allow pull bar on the iron core (sheet) pass wherein, so that permanent magnetism physical efficiency and moving iron core (sheet) adhesive when unlocking condition make its state obtain stable the maintenance and not consuming electric power.2, adopt the conversion of moving iron core (sheet) state of pulse current control, to reach required lock-out state or release conditions.
The beneficial effects of the utility model are: 1, in (generally being electromagnetic actuation) this following period of time of opening the door, below 1/100 of non-bistable state product is approximately reduced in the electromagnet power consumption.2, present technique make to adopt electromagnet realize that " often opening " state of locking becomes possibility, and is being used for office or was not wishing that the occasion of frequent switch door must finish by the more electric system of operational failure in the past.3, since electromagnetic actuation and discharge system in two states stability (as vibration proof, anti-outside magnetic interference) be greatly improved, so the fault rate of complete machine significantly reduces.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further illustrated.
Accompanying drawing is the structural representation according to the designed horizontal bistable electro-magnet of the scheme that the utility model proposes.
1. moving iron core (being lock core, lock pin) or moving iron plate, 2. magnetic conduction support, 3. solenoid, 4. back-moving spring, 5. permanent magnet, 6. stops among the figure.Wherein solenoid can be 1 or 2, and 2 solenoidal system, control circuits are simpler.
Embodiment:
Shown in dotted portion in the accompanying drawing, at common state (lock-out state), moving iron core or moving iron plate (1) stretch out, stop (6) has been placed restrictions on its extension elongation, because stretching out of it, stopped and the action of the fork of door locking handle interlock that guarantee that door locking handle can not rotate, door just can not be opened.
When needs are unblanked, in solenoid (3), pass to direct impulse electric current (added, opposite with aforementioned direction pulse current was oppositely when our definition was locked a door accordingly), because the effect of electromagnetic force, the elastic force that lock core overcomes spring (4) moves to right, and is positioned at permanent magnet (5) the institute adhesive of the right-hand inboard of magnetic conduction support (2) until its right-hand member.Obviously, because lock core held, door locking handle is rotated and open the door.
Owing in system, installed permanent magnet (5), thereby moving iron core (1) only needs the effect (for example about 15ms) of moment electromagnetic force just can change original state, and on solenoid of the present utility model, need not to consume any energy maintained in arbitrarily long-time, and this system for dry cell power supply is crucial.
When the needs device when unlocking condition becomes lock-out state, only need on solenoid (3), to pass to the reverse impulse electric current and get final product.
Claims (3)
1. a computer is locked and is used bistable electro-magnet, mainly by moving iron core or moving iron plate (1), magnetic conduction support (2), solenoid (3), back-moving spring (4), stop (6), etc. form, it is characterized in that: installed the permanent magnet (5) that opposite side posts magnetic conductive iron sheet additional in the inboard of magnetic conduction support right-hand member, make it when unlocking condition can with moving iron core or moving iron plate (1) adhesive and stable its state that keeps mutually.
2. use bistable electro-magnet by the described computer lock of claim 1, it is characterized in that: the moving iron core of a permanent magnet and a locking action or moving iron plate are on same axis.
3. use bistable electro-magnet by the described computer lock of claim 1, it is characterized in that: permanent magnet is circular, so that pass the pull bar on moving iron core or the moving iron plate from the annulus hole.
