Referring to fig. 1 to 2, an embodiment of the invention discloses a driving member 10. In particular, the drive member 10 comprises a triggering device 12, a motor 14 and a control device 13.
The trigger device 12 is used for generating an unlocking signal and a speed regulating signal. The control device 13 is connected with the motor 14 and the trigger device 12, and the control device 13 is used for unlocking the motor 14 according to the unlocking signal and controlling the rotating speed of the motor 14 according to the speed regulating signal when the motor 14 is in the unlocking state.
According to the driving part 10 of the embodiment of the invention, through the arrangement of the trigger device 12 and the control device 13, a user can realize the on-off of the motor 14 and the adjustment of the rotating speed of the motor 14 through the trigger device 12, so that the operation is more convenient, the user can conveniently operate with one hand, and the user experience is improved.
In some embodiments, the triggering device 12 comprises an unlocking element 122 and a speed regulation element 123, the unlocking element 122 and the speed regulation element 123 are both connected with the control device 13, the unlocking element 122 is used for generating an unlocking signal, and the speed regulation element 123 is used for generating a speed regulation signal.

In some embodiments, the trigger device 12 includes an operating portion 121, an unlocking element 122 connected to the operating portion 121, the unlocking element 122 being configured to sense an unlocking operation on the operating portion 121 to generate an unlocking signal. The speed adjusting element 123 is connected to the operation part 121, and the speed adjusting element 123 is used for sensing a speed adjusting operation of the operation part 121 to generate a speed adjusting signal.
The unlocking element 122 and the speed regulating element 123 are both connected with the operating part 121, so that a user can unlock the motor 14 and/or change the rotating speed of the motor 14 only by operating the operating part 121, and the user can conveniently operate the motor with one hand. In some embodiments, the unlocking operation comprises a touch operation and/or a press operation and/or the pacing operation comprises a press operation.
The unlocking operation refers to the operation portion 121 receiving contact and/or pressing by an external object. Alternatively, the operating portion 121 may generate an unlocking signal when touched and/or pressed by an external object.
For example, when the user touches the operation portion 121 with a finger, the operation portion 121 detects that the user touches or presses the operation portion 121 with a hand, the operation portion 121 generates an unlock signal and transmits the unlock signal to the unlock element 122, the unlock element 122 receives the unlock signal and feeds the unlock signal back to the control device 13, the control device 13 unlocks the motor 14 after receiving the unlock signal, and the motor 14 in the unlock state can rotate freely.
That is, when the finger of the user is far away from the operating portion 121, the operating portion 121 detects and recognizes that the finger of the user is far away from the operating portion 121, and the operating portion 121 does not detect the unlocking operation, that is, the operating portion 121 does not recognize the unlocking operation, and the unlocking element 122 does not receive the unlocking signal, and the unlocking element 122 does not feed the unlocking signal back to the control device 13, and the control device 13 does not receive the unlocking signal, so the control device 13 continues to lock the motor 14, and at this time, the motor 14 cannot rotate, and at this time, the motor 14 belongs to the locked state.
The speed adjustment operation means that the operation portion 121 receives a press from an external object. Alternatively, the operation portion 121 may generate a speed control signal when pressed by an external object.
For example, when the user presses the operating portion 121 with a finger, the operating portion 121 detects that the user presses the operating portion 121 with the finger, the operating portion 121 generates a speed regulating signal and transmits the speed regulating signal to the speed regulating element 123, the speed regulating element 123 receives the speed regulating signal and feeds the speed regulating signal back to the control device 13, and the control device 13 receives the speed regulating signal and adjusts the rotation speed of the motor 14.
That is, when the finger of the user is far away from the operating portion 121, the operating portion 121 detects and recognizes that the finger of the user is far away from the operating portion 121, and the operating portion 121 does not detect the speed regulation operation, that is, the operating portion 121 does not recognize the speed regulation operation, and the speed regulation element 123 does not receive the speed regulation signal, and the speed regulation element 123 does not feed the speed regulation signal back to the control device 13, and the control device 13 does not receive the speed regulation signal, so the control device 13 does not adjust the rotation speed of the motor 14.
Referring to fig. 2 to 4, in some embodiments, the unlocking element 122 is located on the top surface of the driving member 10, the speed adjusting element 123 is located on the side of the driving member 10, or both the unlocking element 122 and the speed adjusting element 123 are located on the top surface of the driving member 10.
The unlocking element 122 and the speed regulation element 123 may be connected to the operating part 121 through wires, and it is understood that the unlocking element 122 and the speed regulation element 123 may not only be connected through wires, but also may be connected in different manners according to different situations, for example, the unlocking element 122 and the speed regulation element 123 may be connected through bluetooth. The connection between the unlocking element 122 and the speed adjusting element 123 and the operating part 121 is not limited to a large extent.
So set up, simple structure, convenient operation. In addition, the motor 14 needs to be unlocked and rotated when the operation portion 121 is pressed, so that the operation safety of the driving member 10 is improved, and the user experience is improved.
Wherein the unlocking operation and the speed regulating operation are the same touch. Thus, the user does not need to touch and/or press the operating part 121 with a finger to unlock the motor 14, and then lift the finger and then press the operating part 121 to rotate the motor 14, so that unlocking and rotating of the motor 14 are controlled more conveniently, and user experience is improved.
Further, the motor 14 can rotate after being unlocked, that is, after the control device 13 unlocks the motor 14 according to the unlocking signal received by the unlocking element 122, the control device 13 controls the rotating speed of the motor 14 according to the speed regulating signal received by the speed regulating element 123, so that the motor 14 can be prevented from being started accidentally due to the fault of any electronic element in the circuit, and the safety performance of the driving part 10 is improved.
Therefore, the user can unlock the motor 14 and rotate the rotating speed only by touching and/or pressing the operation part 121, the user can operate the motor with one hand conveniently, and the user experience is improved.
In some embodiments, the driving member 10 includes a body 11, the triggering device 12 is disposed on the body 11, and the motor 14 and the control device 13 are disposed in the body 11.
The body 11 is substantially cylindrical. The body 11 may be made of plastic and/or metal material. The body 11 can protect internal components such as the control device 13 and the motor 14 from being damaged. The body 11 may be a waterproof sealing structure, that is, external liquid cannot enter the body 11 through the body 11, thereby increasing the life of the driving part 10.
Further, the part of the operation part 121 exposes the machine body 11, and the part of the operation part 121 exposing the machine body 11 is close to the surface of the machine body 11 in height, so the product is more beautiful, the pressing stroke (the pressing stroke can be less than 1mm) of the speed regulation element 123 can be greatly reduced, and thus the user can easily realize the rotating speed of the one-key micro-stroke control motor 14, and the user experience is improved.
In some embodiments, the unlocking element 122 comprises a touch sensor or a push switch, and the speed adjusting element 123 comprises at least one of a pressure sensor, a potentiometer, and a sliding element.
Specifically, the unlocking element 122 may be a capacitive element, and when the user touches the operation portion 121 with a finger, the unlocking element 122 feeds back capacitance data to the control device 13, and the control device 13 unlocks the motor 14 after receiving the capacitance data. Of course, the unlocking element 122 may not be only a capacitive element, but different elements may be used according to different situations. For example, the unlocking element 122 may be a temperature sensor, an ultrasonic sensor, a touch sensor, or a push switch.
The pressure sensor can sense a pressure signal, convert the pressure signal into an available output electric signal according to a certain rule, and transmit the electric signal to the control device 13, and the control device 13 controls the motor 14 to rotate according to the received electric signal. The potentiometer includes a resistor body and a sliding system, the sliding system can be connected with the operation part 121, when a user presses the operation part 121 with a finger, a moving contact of the sliding system moves on the resistor body, so that the voltage of the potentiometer can be changed, the potentiometer converts the voltage into a usable electric signal and transmits the electric signal to the control device 13, and the control device 13 controls the motor 14 to rotate according to the received electric signal. The sliding element may be a sliding rheostat that controls the rotation of the motor 14 by varying the resistance to achieve varying voltage levels.
In the present embodiment, the unlocking element 122 is located inside the operation portion 121, so that the user can conveniently operate the unlocking element by one key. It is understood that the unlocking element 122 may be located not only inside the operating portion 121, but also in different positions according to different needs.
In some embodiments, the unlocking element 122 is located between the operating part 121 and the speed regulating element 123. Alternatively, the operating portion 121, the unlocking member 122, and the speed adjusting member 123 are provided in this order along the outside of the body 11 toward the inside of the body 11. This arrangement makes the trigger device 12 more compact.
In some embodiments, referring to fig. 2, the triggering device 12 includes a force transmitting element 124 disposed between the operating portion 121 and the regulating member 123, the force transmitting element 124 being used to transmit the pressure of the regulating operation to the regulating member 123.
The force transmitting element 124 is capable of transmitting the pressure of the governor operation to the governor element 123, so that the governor element 123 is capable of receiving the pressure of the governor operation for feedback to the control device 13, and the rotational speed of the motor 14 is controlled by the control device 13.
In some embodiments, the force transmitting element 124 is rod-shaped and extends through the unlocking element 122.
The rod-shaped force transmitting member 124 facilitates the force transmitting member 124 to transmit the pressing force of the governor operation to the governor element 123. Of course, the force-transmitting member 124 may not be just a rod, but may take different shapes depending on the circumstances, for example, the force-transmitting member 124 may be a block.
In certain embodiments, the triggering device 12 comprises a resilient element 15 arranged between the force transmitting element 124 and the throttle element 123.
The elastic element 15 can provide a buffer time interval between the force transmission element 124 and the speed regulation element 123, so that the hand feeling of a user pressing the operation part 121 can be increased, and the user experience is improved.
Specifically, the elastic element 15 may be made of soft plastic, silicone, rubber, metal spring, or other materials, or the elastic element 15 may be made of other materials with other elastic structures.
In some embodiments, the elastic element 15 may be disposed at an end of the force transmitting element 124 facing the speed adjusting element 123, and the elastic element 15 may be disposed at a side of the speed adjusting element 123 facing the force transmitting element 124. In addition, the elastic element 15 can be arranged at one end of the force transmission element 124 facing the speed regulation element 123 and one side of the speed regulation element 123 facing the force transmission element 124, so that the hand feeling of the user for pressing the operation part 121 is increased through the elastic element 15, and the user experience is improved.
In some embodiments, the control device 13 includes a circuit board 131 and a processor 132, and the throttle element 123 is disposed on the circuit board 131. The processor 132 is disposed on the circuit board 131, and the processor 132 is configured to control the state of the motor 14 according to the unlocking signal and the speed-adjusting signal.
The arrangement of the circuit board 131 and the processor 132 enables the drive unit 10 to better control the state of the motor 14, resulting in a more efficient operation of the motor 14.
Specifically, the circuit board 131 may be a rigid printed circuit board 131, and of course, the circuit board 131 may not be only the rigid printed circuit board 131, but may be used instead of the circuit board 131 according to different situations, for example, the circuit board 131 may be a flexible circuit board 131.
In some embodiments, the governor element 123 is configured to detect a current pressure generated by pressing the operation portion 121, and the processor 132 is configured to control the rotation speed of the motor 14 according to the current pressure, wherein the rotation speed of the motor 14 is in positive correlation with the pressure generated by pressing the operation portion 121.
The rotation speed of the motor 14 increases as the current pressure magnitude increases, and the rotation speed of the motor 14 decreases as the current pressure magnitude decreases. So can make the rotational speed of motor 14 change along with the change of current pressure size, the user wants the rotational speed just to press operating portion 121 heavy bit fast, wants the rotational speed just to press operating portion 121 light bit slowly, and the operation is very convenient, and convenience of customers controls motor 14 rotational speed, promotes user experience.
In some embodiments, the control device 13 is preset with a corresponding relationship between the pressure section and the rotation speed, and the rotation speed of the corresponding motor 14 is increased as the pressure of the pressure section is increased. The processor 132 is configured to determine a pressure segment where the current pressure is located, and control the rotation speed of the motor 14 according to the pressure segment where the current pressure is located and the corresponding relationship.
The pressure section is arranged to make it easier to match the rotation speed of the motor 14 with the current pressure, so that the rotation speed of the motor 14 is more stable and the rotation of the motor 14 is more efficient. The processor 132 can match the current pressure and the pressure section, and control the motor 14 to rotate at the corresponding rotating speed according to the rotating speed of the motor 14 corresponding to the pressure section where the current pressure is located, so that the situation that the current pressure is not matched with the pressure section does not occur, and the rotating efficiency of the motor 14 is improved.
In certain embodiments, the processor 132 is configured to calibrate the throttle element 123 based on the pressure of the throttle operation before the motor 14 is unlocked.
Since a certain pressure may occur when the user touches the operation portion 121, the pressure needs to be calibrated, and an error can be prevented from occurring after calibration, so that the rotation speed and the pressure of the motor 14 can be better matched.

In this way, the current pressure R1 of the speed regulation operation can fall into different pressure segments, and the processor 132 controls the motor 14 to rotate at a corresponding rotation speed according to the rotation speed corresponding to the corresponding pressure segment. For example, the current magnitude R1 of the pressure of the governor operation is 125 Ω, and the current magnitude R1 of the pressure of the governor operation is located in the eighth pressure stage, i.e., the 7 th gear, so that the processor 132 controls the motor 14 to rotate at the rotation speed corresponding to the 7 th gear, i.e., the rotation speed of the motor 14 is 8000 rmp.
Of course, the gear can be not only 9, but also different gears can be adopted according to different requirements, for example, the gear can be 2, 3, 13, 15, and the like, and the gears can be divided according to actual conditions. When the number of gears is larger, the rotation speed change of the motor 14 is smoother and closer to the stepless speed change. The smaller the number of gear positions, the more obvious the change of the rotation speed of the motor 14 is.
Further, the processor 132 may set a highest pressure RH of the motor 14, and when the current magnitude R1 of the pressure of the speed regulation operation obtained by the speed regulation element 123 is greater than the highest pressure RH, the motor 14 rotates according to a rotation speed corresponding to when the current magnitude R L of the pressure of the speed regulation operation reaches the highest pressure RH.

However, by the processor 132 unlocking the motor 14 after the unlocking element 122 receives the unlocking operation for a predetermined period of time, such a situation can be effectively prevented from occurring, thereby improving the safety of the driving part 10.
Wherein the predetermined period of time may be 3 seconds, or 4 seconds, or may be 5 seconds.
