Summary of the application
As described above, the conventional electronic lock implements the locking driving process and the unlocking driving process through the set driving time.
Fig. 1 illustrates a driving schematic diagram of a conventional electronic lock. As shown in fig. 1, the motor is normally rotated (locked) when a forward voltage is applied thereto, and is reversely rotated (unlocked) when a reverse voltage is applied thereto. In order to protect the motor, the duration T1 of the forward voltage and the reverse voltage cannot exceed the motor specification set value; and, this T1 value of different motors is also all different, when T1 is not more than the specification value, also need to reduce the subsequent drive time after the motor drives in place to reduce the mechanism transmission stress when the locked rotor.
However, if the driving time T1 is set too short, it may cause the locking or unlocking not to be in place, and if the driving time T1 is set too long, it may cause the motor to be locked and the transmission mechanism to be stressed for too long, which may affect the life of the motor and the life of the transmission mechanism. Moreover, since the driving times set by different motors are different, developers of control modules of the motors need to modify and adjust the set driving times according to the different motors used.
In view of the above technical problems, the basic idea of the present application is to automatically trigger the disconnection of the driving voltage of the motor movement when the motor moves to a predetermined state, for example, the motor of the electronic lock moves to lock or unlock, instead of controlling the driving voltage of the motor through the driving time of the motor.
Specifically, the present application provides a motor apparatus including: 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 present application provides a motor drive control apparatus including: a switching device; and a control device comprising: a state detection unit for detecting whether the motor moves to a predetermined state; and a voltage cutoff unit for controlling the switching device to cut off the driving voltage of the motor in response to the motor moving to a predetermined state.
Like this, the electrical equipment and the motor drive controlgear that this application provided can break off the voltage of driving motor motion when the motor moves to the predetermined condition to realized the real-time motion protection of motor, reduced stalling time and transmission stress, improved motor itself and drive mechanism's life.
And, through responding to the motor and moving to the predetermined state and cutting off the driving voltage of the motor, even for different motors, need not consider its drive time yet, thus make the motor developer while developing and debugging the control module of the motor, have reduced the work difficulty and work load.
It is to be noted that, in the motor apparatus provided in the present application, the motor is not limited to the motor of the electronic lock, but may be various motors whose driving needs to be controlled.
Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.
Illustrative apparatus
Fig. 2 illustrates a block diagram of an electric machine according to an embodiment of the present 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 moving 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 said first voltage in response to said motor 120 moving in said first direction to a first state and/or switching off said second voltage in response to said motor 120 moving in said 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 supply for applying a voltage, or may not include a power supply, but may include a device for receiving a voltage applied by an external power supply, 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 configured to apply a positive voltage and a negative voltage, but the embodiment of the present application is not limited thereto, and the first voltage and the second voltage may also be two-phase voltages having different directions, for example, different directions with a phase difference of 120 degrees between each other in 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, the first direction and the second direction may include various directions such as a translational direction and a rotational direction for different motors, and thus, in the 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 and a rotational movement.
The control unit 130 is configured to control on/off of the driving voltage of the motor 120, and as described above, in order to realize the control of the motor 120 that is not dependent on the driving time, the control unit 130 controls the motor through the motion state of the motor 120, for example, the locking/unlocking state of the motor of the electronic lock as described above. In particular, the control unit 130 may disconnect the first voltage in response to the motor 120 moving in the first direction to a first state, and/or disconnect the second voltage in response to the motor 120 moving in the second direction to a second state.
Here, the control unit 130 may determine the motion state of the motor 120 by detecting the motion position of the motor 120, for example, for a motor that moves in translation, it may detect whether the motor 120 moves to a predetermined spatial position, and for a motor that moves in rotation, it may detect whether the motor 120 moves to a predetermined angular position.
Therefore, according to the motor equipment provided by the embodiment of the application, the driving voltage of the motor can be automatically cut off when the motor moves to a preset state, so that the real-time motion protection of the motor is realized, the stalling time and the transmission stress are reduced, and the service lives of the motor and the transmission mechanism are prolonged.
And, through responding to the motor and moving to the predetermined state and cutting off the driving voltage of the motor, even for different motors, need not consider its drive time yet, thus make the motor developer while developing and debugging the control module of the motor, have reduced the work difficulty and work load.
Next, a specific control example of the motor device according to the embodiment of the present application will be further described with reference to fig. 3 to 9, taking the motor device as an example of a motor applied to an electronic lock.
Fig. 3 illustrates a schematic diagram of an exemplary control circuit of a motor apparatus according to an embodiment of the present application.
Fig. 4 illustrates a schematic diagram of an exemplary control arrangement of a motor apparatus according to an embodiment of the present application. Fig. 5 illustrates a schematic diagram of an exemplary modular arrangement of an electromechanical machine 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-activated micro/tact switches, and as shown in fig. 5, are activated to close/open by the dome in response to movement of the motor.
As shown in fig. 3, in the locking control voltage, D + is positive voltage, D-is negative voltage, and the motor is driven in the forward direction, while in the unlocking control voltage, D + is negative voltage, D-is positive voltage, and the motor is driven in the reverse direction. In the locked initial state, S1 is open and S2 is closed; in the unlock initial state, S1 is closed and S2 is opened, and during the motor driving, S1 is opened and 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 motor apparatus of an electronic lock in a locked-in-place state 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 the forward voltage is applied to D +/D-, i.e. D + is the voltage positive V + and D-is the voltage negative V-. In the initial state, Q1 is on, Q2 is off, S1 is off, and S2 is on. Here, it can be understood by those skilled in the art that in the embodiment of the present application, the initial state of locking is the in-place state of unlocking, and as will be further explained below, in the in-place state of unlocking, S1 is opened and S2 is closed. Also, as described above, both S1 and S2 are opened during the lock-up process, and thus S2 is configured to be closed before the lock lever of the motor-driven electronic lock is moved and to be opened after the lock lever is moved.
The motor drive execution course current flows as 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 to a proper position, the triggering elastic sheet contacts the micro/tact switch S1 and closes the micro/tact switch S1. 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 S1 is closed, the transistor Q2 is driven to be turned on, the transistor Q2 is driven to be turned on, and the transistor Q1 is driven to be 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 a LOCK-in-position state feedback signal F-LOCK, which is changed as follows: after the driving voltage is applied, the micro/tact switch S1 is turned off 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 apparatus of an electronic lock according to an embodiment of the present application. Fig. 9 illustrates a module diagram in an unlocked-in-position state of a motor apparatus of an electronic lock according to an embodiment of the present application.
As mentioned above, when the electronic lock is in the locked state, the unlocking driving process is started, and the reverse voltage is applied to D +/D-, that is, D + is the voltage negative V-, and D-is the voltage positive V +. In the unlocked initial state, 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 is moved and to be open after the lock lever is moved.
The motor drive execution course current flows as shown in the left portion of fig. 8, i.e., D- → Q3 → M → D1 → D +.
Unlocking when the motor moves to a second state, for example, when the lock rod of the electronic lock is driven to move to a position, the trigger spring plate contacts the micro/tact switch S2 and closes the micro/tact switch S2. 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 transistor Q4 is driven to be conducted, the transistor Q4 is conducted, and the transistor Q3 is driven to be cut off, so that a motor driving loop is cut off, and the motor stops running.
Likewise, it may be determined whether the motor has moved to the second state by setting the UNLOCK-to-position state feedback signal F-UNLOCK. The UNLOCK-in-place state feedback signal F-UNLOCK varies as follows: after the driving voltage is applied, the micro/tact switch S2 is turned off before unlocking to the proper position, F-UNLOCK is in a low potential state V-, and S2 is in a closed state after locking to the proper position, and F-UNLOCK is in a high potential state V +.
Here, it may be understood by those skilled in the art that, although the control circuit is exemplified as a circuit for integrally controlling the locking and unlocking processes of the electronic lock in fig. 3 to 9, in the embodiment of the present application, the control unit may include a switch unit for controlling the motor to be turned off in the first state and the second state, respectively.

Also, in the motor apparatus according to the embodiment of the present application, the voltage applying unit applies the third voltage in a third loop including a third control element between the positive voltage and the negative voltage; the control unit comprises a second switch unit, and the second switch unit is used for responding to the motor moving to a second state in the second direction and being triggered to conduct a fourth control element; the turning 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, although the circuit loops are controlled to be turned on and off by transistors in fig. 3 to 9, the transistors may be replaced by MOS transistors or other switching elements, as will be understood by those skilled in the art.

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 one ends of the first switching unit and the second switching unit opposite to the voltage applying unit.
Therefore, even if the motor equipment according to the embodiment of the application drives different motors, the drive protection time of the motor equipment does not need to be considered, so that the difficulty and the workload of a user of the motor equipment are greatly reduced when the user develops and debugs the control module.
In addition, the motor equipment has a real-time locked rotor protection function, locked rotor time and transmission stress are reduced, the service life of the motor is prolonged, and the service life of the transmission mechanism is prolonged.
