Specific implementation mode
The present invention is described in further detail with reference to the accompanying drawings and examples.
A kind of efficient electrically controlled latch gear of the present invention, as shown in Figure 1：Including shell 2；Shell 2 is equipped with coil block
Power supply interface 1 and circuit board interface 7；Magnetic guiding frame 3 and circuit board 4 are equipped in shell 2；Magnetic guiding frame 3 is equipped with coil block 9；Line
Coil assembly 9 is electrically connected with coil power supply interface 1；Axis pin 5 is equipped in coil block 9,5 one end of axis pin is equipped with bipolarity magnet steel group
Part 6,5 other end of axis pin stretch out shell 2；Circuit board 4 is equipped with Hall sensor 10, and circuit board 4 electrically connects with circuit board interface 7
It connects.Hall sensor 10 on circuit board 4 is located near bipolarity magnetic steel component 6；Hall sensor 10 uses Hall switch collection
At circuit.RC filter circuits 8 are equipped between signal output end Uout on circuit board 4 and ground terminal GND.Axis pin 5 is located at coil
In the centre bore of component 9, and it is slidably connected with the centre bore of coil block 9；Axis pin 5 is connect with the armature of coil block 9.
Embodiment
The efficient electrically controlled latch gear of this example is used for the locking and unlock of servo-drive system.This example includes a coil block,
Axis pin is placed in coil center, and a bipolarity magnet steel is installed on axis pin, passes through Hall sensor and processing circuit detection unlock letter
Number.
Specifically as shown in Figure 1, by coil block power supply interface 1, shell 2, magnetic guiding frame 3, circuit board 4, axis pin 5, bipolarity
Magnetic steel component 6, circuit board interface 7, RC filter circuits 8, coil block 9, Hall sensor 10 and spring 11 form.
Axis pin 5 is active pin shaft, and Hall sensor 10 uses hall ic to pacify as position detection component
On the circuit board 4, bipolarity magnetic steel component 6 is mounted on axis pin 5 dress.When coil block 9 is connect by coil block power supply interface 1
When energization source, coil block 9 magnetizes armature, and the armature being magnetized and magnetic guiding frame 3 generate larger electromagnetism the suction-combining force and axis pin 5 driven to transport
Dynamic, axis pin 5 drives bipolarity magnetic steel component 6 to move, and so that bipolarity magnetic steel component 6 is covered or be detached from Hall sensor 10, realizes
Lock pin 5 is attracted or locking, while Hall sensor 10 exports feedback signal.The present invention has the characteristics that simple in structure.Using suddenly
The height of your switching device output voltage judges the state of lock pin, has a stronger versatility.
The course of work and principle of the present invention
The device of the invention is fixed on the boss locking disk on motor shaft by the flexible interference of axis pin 5, is locked and is unlocked.
Axis pin 5 stretches out under the effect of spring 11 when power-off, is inserted between two boss, and motor is prevented to rotate；And axis pin 5 is received when being powered
It returns, non-interference with boss, motor can be freely rotated.When 9 no power of coil block, spring 11 is in relaxation state, bullet
The axial compressive force that spring 11 generates moves the direction for pushing armature to be extended to spring 11, the axis pin 5 and brake disc being connect with armature
On slot contraposition accurately in the case of, axis pin 5, which can correspond to, to be fallen into corresponding slot, if rotary electric machine axis at this time, due to brake disc
It is fixed on motor shaft, and axis pin 5 is stuck in brake disc, therefore the angular range that motor shaft can rotate only brakes dish groove institute
The range of limitation.In such a way that axis pin 5 limits, motor shaft and rudder face can be locked in by electromagnetism locking device allows error of zero model
In enclosing, the lock function of the electromagnetism locking device is realized.
