Abstract
The utility model discloses a direct-current motor with an antitheft latching mechanism, and belongs to the field of safety control equipment. The motor can control an armature to be inserted into or depart from a motor-rotor output shaft through a relay, so as to enable the motor-rotor output shaft not to move freely during power-off or illegal use, thereby achieving the antitheft purpose.
Description
Technical field
The utility model relates to a kind of DC motor that possesses anti-theft feature, refers in particular to and adopts electromagnet to carry out the DC motor of anti-theft locking.
Background technology
At present, the rotor of known DC motor also can freely rotate when no power, does not carry out locking, and like this, motor, cold time, also can make motor rotor rotate by external force.For example, if when this motor is used for needing antitheft equipment (electric bicycle, electric automobile), for example, as long as destroyed other burglar-proof mechanism (lock) of equipment, just can use Manual-pushing equipment moving, be unfavorable for antitheft.
Summary of the invention
In order to overcome the deficiency that DC motor can not locking in no power situation, the utility model provides a kind of novel burglary-resisting system, the electromagnet of the enough employing DC power supply of this system energy carries out locking to DC motor, allow motor automatic locking in the situation that of power-off or the legal use of with no authorized, thereby realize stable effectively antitheft.
The utility model solves the technical scheme that its technical problem adopts: on the armature spindle of DC motor, process a groove and a locking armature controlling organization, the motion of its locking armature is the control that is subject to an electromagnet.Locking armature is fixed on a spring, and the thrust that spring provides is less than the suction that electromagnet provides.Locking armature is stuck in a groove on armature spindle, and motor cannot be rotated, even motor energising, as long as armature does not leave groove, motor rotor just cannot move.The break-make of electromagnet is subject to a Control, when the control relay of motor energising and locking armature is closed, the electromagnet energising that armature connects, produce magnetic field, the attraction of initiation to armature, when attraction is greater than the thrust of spring, armature leaves motor rotor groove, so the rotor of motor can rotate freely, and normally works.
The beneficial effects of the utility model are that, when it does not have energising or Control terminal not to input significant level, the locking armature of motor output shaft will snap in the groove of motor output shaft, thereby motor cannot be moved, has increased the anti-theft capability of product.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, motor rotor, 2, motor rotor groove, 3, locking armature, 4, spring, 5, electromagnet, 6, relay, 7, positive source, 8, Control terminal
In Fig. 1: when power supply is not connected, (8) there is no voltage, or when Control terminal (8) does not have voltage, (5) cannot adhesive, locking armature (3) snaps in the motor rotor groove (2) of motor rotor (1) like this, and motor rotor (1) cannot be rotated; Once power connection, or Control end has been inputted control voltage, the switch connection that relay (6) is inner, make electromagnet (5) have electric current to pass through, so generation magnetic force, attracts locking armature (3), when suction is greater than spring (4) to the thrust of locking armature (3), locking armature (3) is sucked from motor rotor (1), so motor rotor (1) can freely rotate.If the unexpected voltage out of hand of Control terminal (8) or power supply suddenly disappear, the inner switch of relay (6) will disconnect, the suction of electromagnet (5) disappears, spring (4) promotes locking armature (3) and is close to motor rotor (1), at this moment, motor rotor (1) rotates at most 1 circle, locking armature (3) will snap in the motor rotor groove (2) of motor rotor (1), motor rotor (1) locking, cannot free movement.
Claims (7)
1. a DC motor that possesses anti-theft locking mechanism, is characterized in that output shaft processed a groove and a locking armature controlling organization;
Described locking armature controlling organization comprises: locking armature, spring, electromagnet, relay, power connector end, Control terminal.
2. a kind of DC motor that possesses anti-theft locking mechanism as claimed in claim 1, while it is characterized in that it is not switched on or Control terminal does not input significant level, the locking armature of motor output shaft will snap in the groove of motor output shaft, and motor cannot be moved.
3. a kind of DC motor that possesses anti-theft locking mechanism as claimed in claim 1, is characterized in that its armature is fixed on a spring, and the thrust that spring provides is less than the suction that electromagnet provides.
4. a kind of DC motor that possesses anti-theft locking mechanism as claimed in claim 1, is characterized in that the motion of its locking armature is subject to a magnet control.
5. a kind of DC motor that possesses anti-theft locking mechanism as claimed in claim 1, is characterized in that the break-make of its electromagnet is subject to a Control.
6. a kind of DC motor that possesses anti-theft locking mechanism as claimed in claim 1, the break-make that it is characterized in that its electromagnet is controlled by the level of a Control terminal input.
7. a kind of DC motor that possesses anti-theft locking mechanism as claimed in claim 1, is characterized in that the power supply that power supply that its electromagnet is used is used with motor is identical, and is all direct current.
