Detailed Description
Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the described embodiments are only some of the embodiments of the application, and not all of the embodiments of the application, and that the application is not limited to the example embodiments described herein.
Summary of the application
As described above, the conventional electronic lock implements the locking driving process and the unlocking driving process by the set driving time.
Fig. 1 illustrates a driving schematic of a conventional electronic lock. As shown in fig. 1, the motor rotates forward (locks) when applying a forward voltage, and rotates backward (unlocks) when applying a reverse voltage. In order to protect the motor, the duration time T1 of the forward voltage and the reverse voltage cannot exceed the motor specification set value; and the T1 values of different motors are different, and when the T1 value is not more than the specification value, the subsequent driving time is required to be reduced after the motor is driven in place, so that the mechanism transmission stress in locked rotation is reduced.
However, if the driving time T1 is set too short, locking or unlocking may not be performed in place, and if the driving time T1 is set too long, the motor is locked and the stress time of the transmission mechanism is too long, which affects the service life of the motor and the service life of the transmission mechanism. Moreover, since the driving time set by different motors is not the same, the developer of the control module of the motor needs to modify and adjust the set driving time according to the different motors used.
The basic idea of the present application is to automatically trigger the drive voltage to turn off the motor movement when the motor moves to a predetermined state, for example, when the motor of the electronic lock moves to lock or unlock, instead of controlling the drive voltage of the motor by the drive time of the motor.
Specifically, the motor apparatus provided by the present application includes: a voltage applying unit for applying a first voltage in a first direction and a second voltage in a second direction different from the first direction; a motor for moving in a first direction in response to the first voltage and in a second direction different from the first direction in response to the second voltage; a control unit for switching off the first voltage in response to the motor moving in the first direction to a first state and/or switching off the second voltage in response to the motor moving in the second direction to a second state.
Also, the motor drive control apparatus provided by the present application includes: a switching device; and a control device including: a state detection unit for detecting whether the motor moves to a predetermined state; and a voltage disconnection unit for controlling the switching device to disconnect a driving voltage of the motor in response to the motor moving to a predetermined state.
Therefore, the motor equipment and the motor drive control equipment provided by the application can disconnect the voltage for driving the motor to move when the motor moves to a preset state, so that the real-time motion protection of the motor is realized, the locked-rotor time and the transmission stress are reduced, and the service lives of the motor and the transmission mechanism are prolonged.
In addition, by switching off the driving voltage of the motor in response to the motor moving to a predetermined state, even for different motors, the driving time thereof does not need to be considered, so that the work difficulty and the workload are reduced when a motor developer develops and debugs the control module of the motor.
It is to be noted that, in the motor apparatus provided by the present application, the motor is not limited to the motor of the electronic lock, but may be various motors required to control the driving thereof.
Having described the basic principles of the present application, various non-limiting embodiments of the present application will now be described in detail with reference to the accompanying drawings.
Schematic apparatus
Fig. 2 illustrates a block diagram of an electric machine according to an embodiment of the application.
As shown in fig. 2, the motor apparatus 100 according to the embodiment of the present application includes: a voltage applying unit 110 for applying a first voltage in a first direction and a second voltage in a second direction different from the first direction; a motor 120 for moving in a first direction in response to the first voltage applied by the voltage applying unit 110 and in a second direction different from the first direction in response to the second voltage applied by the voltage applying unit 110; a control unit 130 for switching off the first voltage in response to the motor 120 moving in the first direction to a first state and/or switching off the second voltage in response to the motor 120 moving in the second direction to a second state.
It should be noted that, in the embodiment of the present application, the voltage applying unit 110 may include a power source for applying a voltage, or may not include a power source, but may be a device for receiving a voltage applied by an external power source, for example, may be implemented as a positive voltage input node and a negative voltage input node for receiving an external voltage input.
For the motor of the electronic lock as described above, the voltage applying unit 110 is used to apply the positive voltage and the negative voltage, but the embodiment of the present application is not limited thereto, and the first voltage and the second voltage may be two-phase voltages having different directions, for example, different directions, which are 120 degrees out of phase with each other, among the three-phase voltages.
The motor 120 is configured to move in a first direction in response to the first voltage and in a second direction different from the first direction in response to the second voltage. Also, for different motors, the first direction and the second direction may include various directions such as a translational direction, a rotational direction, etc., and thus, in an embodiment of the present application, the movement of the motor 120 in the first direction and the second direction may also be various movements such as a translational movement, a rotational movement, etc.
The control unit 130 is configured to control on/off of a driving voltage of the motor 120, and as described above, in order to achieve control of the motor 120 independent of a driving time, the control unit 130 controls the motor by a moving state of the motor 120, for example, a locked/unlocked state of the motor of the electronic lock as described above. Specifically, the control unit 130 may turn off the first voltage in response to the motor 120 moving to a first state in the first direction, and/or turn off the second voltage in response to the motor 120 moving to a second state in the second direction.
Here, the control unit 130 may determine the movement state of the motor 120 by detecting the movement position of the motor 120, for example, whether the motor 120 moves to a predetermined spatial position for a translational movement of the motor, and whether the motor 120 moves to a predetermined angular position for a rotational movement of the motor.
Therefore, the motor equipment provided by the embodiment of the application can automatically disconnect the driving voltage of the motor when the motor moves to a preset state, thereby realizing the real-time motion protection of the motor, reducing the locked-rotor time and the transmission stress, and prolonging the service lives of the motor and the transmission mechanism.
In addition, by switching off the driving voltage of the motor in response to the motor moving to a predetermined state, even for different motors, the driving time thereof does not need to be considered, so that the work difficulty and the workload are reduced when a motor developer develops and debugs the control module of the motor.
Next, a specific control example of the motor apparatus according to an embodiment of the present application will be further described with reference to fig. 3 to 9, taking the motor apparatus as an example of a motor applied to an electronic lock.
Fig. 3 illustrates a schematic diagram of an exemplary control circuit of an electromechanical device according to an embodiment of the present application. Fig. 4 illustrates a schematic diagram of an exemplary control arrangement of an electromechanical device according to an embodiment of the present application. Fig. 5 illustrates a schematic diagram of an exemplary module arrangement of an electromechanical device according to an embodiment of the present application.
As shown in fig. 3, the exemplary control circuit includes control switches S1 and S2, which are shown in fig. 4 as dome-triggered jog/tact switches, and as shown in fig. 5, are triggered closed/opened by a dome in response to movement of a motor.
As shown in fig. 3, d+ is positive in the lock control voltage, D-is negative in the voltage, and the motor is driven in the forward direction, while d+ is negative in the unlock control voltage, D-is positive in the voltage, and the motor is driven in the reverse direction. In the initial locking state, S1 is opened, and S2 is closed; in the unlocking initial state, S1 is closed, S2 is opened, and during motor driving, S1 is opened, S2 is opened.
Fig. 6 illustrates a circuit schematic diagram of a locking process of a motor apparatus of an electronic lock according to an embodiment of the present application. Fig. 7 illustrates a block diagram of a locked in place state of a motor apparatus of an electronic lock according to an embodiment of the present application.
As shown in FIG. 6, when the electronic lock is in the unlocked state, the locking driving process is started, and a forward voltage is applied to D+/D-, namely D+ is positive voltage V+, and D-is negative voltage V-. In the initial state, Q1 is on, Q2 is off, S1 is off, and S2 is on. Here, it will be understood by those skilled in the art that in the embodiment of the present application, the initial state of locking is an unlocked in-place state, and as will be further described below, in the unlocked in-place state, S1 is open and S2 is closed. Also, as described above, during the locking, both S1 and S2 are opened, and thus S2 is set to be closed before the movement of the lock lever of the motor-driven electronic lock and opened after the movement of the lock lever.
The motor drive execution process current flow is shown in the left part of fig. 6, i.e., D → Q1 → m→ d2→ D-.
When the motor moves to a first state in the locking process, for example, after the lock rod of the electronic lock is driven to move in place, the triggering spring piece contacts the inching/tacting switch S1 and enables the inching/tacting switch S1 to be closed. The circuit state is shown on the right side of fig. 6 and the state of the module is shown in fig. 7. At this time, after the S1 is closed, the driving transistor Q2 is turned on, and the transistor Q2 is turned on and the driving transistor Q1 is turned off, so that the driving circuit of the motor is disconnected and the motor stops running.
Here, whether the motor moves to the first state may be determined by setting the LOCK-in-place state feedback signal F-LOCK, and specifically, the LOCK-in-place state feedback signal F-LOCK varies as follows: after the driving voltage is applied, the inching/tacting switch S1 is opened before locking in place, F-LOCK is in a low potential state V-, S1 is in a closed state after locking in place, and F-LOCK is in a high potential state V+.
Fig. 8 illustrates a circuit schematic diagram of an unlocking process of a motor device of an electronic lock according to an embodiment of the present application. Fig. 9 illustrates a block diagram of the motor apparatus of the electronic lock in an unlocked in-place state according to an embodiment of the present application.
As described above, the unlock drive process is initiated when the electronic lock is in the locked-in-place state, and a reverse voltage is applied at D+/D-, i.e., D+ is a negative voltage V-, and D-is a positive voltage V+. In the initial state of unlocking, Q3 is on, Q4 is off, S2 is off, and S1 is on. Also, during unlocking, both S1 and S2 are open, and thus S1 is set to be closed before the lock lever of the motor-driven electronic lock moves, and open after the lock lever moves.
The motor drive execution process current flows as shown in the left part of fig. 8, i.e., d→q3→m→d1→d+.
The unlocking process triggers the spring to contact the jog/tact switch S2 and cause the jog/tact switch S2 to close when the motor moves to a second state, for example, after the lock lever of the drive electronic lock moves into place. The circuit state is shown in the right part of fig. 8 and the state of the module is shown in fig. 9. After S2 is closed, the driving triode Q4 is conducted, the driving triode Q3 is cut off, and therefore the motor driving loop is disconnected, and the motor stops running.
Likewise, it may be determined whether the motor is moving to the second state by setting an UNLOCK-in-place state feedback signal F-UNLOCK. The UNLOCK in place state feedback signal F-UNLOCK varies as follows: after the driving voltage is applied, the inching/tacting switch S2 is opened before unlocking in place, F-UNLOCK is in a low potential state V-, S2 is in a closed state after locking in place, and F-UNLOCK is in a high potential state V+.
Here, it will be understood by those skilled in the art that although the control circuit is illustrated as a circuit for integrally controlling the locking and unlocking processes of the electronic lock in fig. 3 to 9, in an embodiment of the present application, the control unit may include a switching unit for controlling the motor to be disconnected in the first state and the second state, respectively.
That is, in the motor apparatus according to the embodiment of the present application, the voltage applying unit applies the first voltage with the first loop including the first control element between the positive voltage and the negative voltage; the control unit comprises a first switch unit for being triggered to turn on a second control element in response to the motor moving in the first direction to a first state; the conduction of the second triode turns on a second loop between the positive voltage and the negative voltage, which includes the second control element, and turns off the first control element.
Also, in the motor apparatus according to the embodiment of the present application, the voltage applying unit applies the third voltage with a third loop including a third control element between the positive voltage and the negative voltage; the control unit comprises a second switch unit for being triggered to turn on a fourth control element in response to the motor moving in the second direction to a second state; the turn-on of the fourth control element turns on a fourth loop including the fourth control element between the positive voltage and the negative voltage, and turns off the third control element.
In addition, it will be appreciated by those skilled in the art that although in fig. 3 to 9, transistors are used to control the on and off of the circuit loop, the transistors may be replaced with MOS transistors or other switching elements.
Therefore, in the motor apparatus according to the embodiment of the present application, the first control element, the second control element, the third control element, and the fourth control element are transistors or MOS transistors.
Also, in the motor apparatus according to the embodiment of the present application, the first loop further includes a first diode connected in series with the first transistor, a conduction direction of the first diode being opposite to the first direction; and the second loop further comprises a second diode connected in series with the third triode, the second diode having a conduction direction opposite to the second direction.
Further, in the motor apparatus according to the embodiment of the present application, the first switch unit and the second switch unit are micro switches or tact switches.
In addition, in the embodiment of the present application, the voltage state between the first and second switching units and the opposite ends of the voltage applying unit may be changed by the closing and opening of the first and second switching units, and thus, whether the motor moves to the first and second states may be monitored using the voltage state.
That is, in the motor apparatus according to the embodiment of the present application, the first switching unit is opened before the motor moves to the first state, and is closed after the motor moves to the first state; the second switching unit is turned off both before and after the motor moves to the first state; the first switching unit is turned off both before and after the motor moves to the second state; and the second switching unit is opened before the motor moves to the second state and closed after the motor moves to the second state.
Also, in the motor apparatus according to the embodiment of the present application, whether the motor moves to the first state and the second state is monitored by a voltage state between the first switching unit and an end of the second switching unit opposite to the voltage applying unit.
Therefore, even for the driving of different motors, the motor equipment provided by the embodiment of the application does not need to consider the driving protection time, so that the difficulty and the workload of a user of the motor equipment are greatly reduced when the control module is developed and debugged.
In addition, the motor equipment provided by the embodiment of the application has a real-time locked rotor protection function, so that the locked rotor time and transmission stress are reduced, the service life of the motor is prolonged, and the service life of a transmission mechanism is prolonged.
In addition, the motor equipment provided by the embodiment of the application realizes double-position in-place state feedback by utilizing the state change of the jog/tact switch, and can accurately realize the driving and protection of the motor by matching with the detection of the monitoring unit.

In one example, in the above-described motor drive control apparatus 200, the state detection unit 221 is configured to detect whether the motor is driven by a forward voltage to rotate in a first direction to a first predetermined state or driven by a reverse voltage to rotate in a second direction opposite to the first direction to a second predetermined state by the state of the switching device 210.
In one example, in the above-described motor drive control apparatus 200, in response to the motor rotating to the first predetermined state, the switching device 210 is triggered to turn off the forward voltage applied to the motor; and, in response to the motor rotating to the second predetermined state, the switching device 210 is triggered to turn off the reverse voltage applied to the motor.
