Referring to fig. 1-2, a driving unit 10 is disclosed in an embodiment of the present invention. Specifically, the driving part 10 includes a triggering device 12, a motor 14, and a control device 13.
The triggering 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 triggering 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 component 10 provided by 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 one-hand operation of the user is convenient, and the user experience is improved.
In some embodiments, the triggering device 12 includes an unlocking element 122 and a speed regulating element 123, the unlocking element 122 and the speed regulating element 123 are both connected to the control device 13, the unlocking element 122 is used for generating an unlocking signal, and the speed regulating element 123 is used for generating a speed regulating signal.
Through the arrangement of the unlocking element 122 and the speed regulating element 123, the triggering device 12 can be used for unlocking the motor 14 and also can be used for regulating the rotating speed of the motor 14, so that a user can operate more conveniently, one-hand operation is facilitated for the user, and user experience is improved.
In some embodiments, the triggering device 12 includes an operation portion 121, and an unlocking element 122 is connected to the operation portion 121, and the unlocking element 122 is configured to sense an unlocking operation on the operation 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 the 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 connected with the operation part 121, so that a user can unlock the motor 14 and/or change the rotation speed of the motor 14 only by operating the operation part 121, and the one-hand operation of the user is facilitated. In some embodiments, the unlocking operation comprises a touch operation and/or a pressing operation and/or the pacing operation comprises a pressing operation.
The unlocking operation means that the operation portion 121 receives contact and/or pressing of an external object. Alternatively, the operating portion 121 may generate the unlock signal when being contacted and/or pressed by an external object.
For example, when the user touches the operation unit 121 with a finger, the operation unit 121 detects that the user touches or presses the operation unit 121 with a hand, the operation unit 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 back the unlock signal to the control device 13, the control device 13 receives the unlock signal and then unlocks the motor 14, and the motor 14 in the unlocked state can freely rotate.
That is, when the user's finger is away from the operation portion 121, the operation portion 121 detects and recognizes that the user's finger is away from the operation portion 121, and at this time the operation portion 121 does not detect the unlocking operation, that is, the operation portion 121 does not recognize the unlocking operation, and at this time the unlocking element 122 does not receive the unlocking signal, the unlocking element 122 does not feed back the unlocking signal to the control device 13, and the control device 13 does not receive the unlocking signal, so that 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 is in the locked state.
The speed adjusting operation means that the operation part 121 is pressed by an external object. Alternatively, the operation unit 121 may generate the speed control signal when pressed by an external object.
For example, when the user presses the operation part 121 with a finger, the operation part 121 detects that the user presses the operation part 121 with a hand, the operation part 121 generates a speed regulation signal and transmits the speed regulation signal to the speed regulation element 123, the speed regulation element 123 receives the speed regulation signal and feeds back the speed regulation signal to the control device 13, and the control device 13 receives the speed regulation signal and adjusts the rotation speed of the motor 14.
That is, when the user's finger is far from the operation part 121, the operation part 121 detects and recognizes that the user's finger is far from the operation part 121, and at this time, the operation part 121 does not detect the speed adjusting operation, that is, the operation part 121 does not recognize the speed adjusting operation, and at this time, the speed adjusting element 123 does not receive the speed adjusting signal, the speed adjusting element 123 does not feed back the speed adjusting signal to the control device 13, and the control device 13 does not receive the speed adjusting 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 part 10, the speed adjusting element 123 is located on the side of the driving part 10, or both the unlocking element 122 and the speed adjusting element 123 are located on the top surface of the driving part 10.
The unlocking element 122 and the speed adjusting element 123 may be connected to the operating portion 121 through wires, it may be understood that the unlocking element 122 and the speed adjusting element 123 may be connected not only through wires, but also in different connection manners according to different situations, for example, the unlocking element 122 and the speed adjusting element 123 may be connected through bluetooth. The connection between unlocking element 122 and governor element 123 and operating section 121 is not excessively limited here.
So set up, simple structure, convenient operation. In addition, the motor 14 can be unlocked and rotated when the operation part 121 is pressed, so that the control safety of the driving part 10 is improved and the user experience is improved.
The unlocking operation and the speed regulating operation are the same touch. In this way, the user does not need to touch and/or press the operation part 121 with a finger to unlock the motor 14, and then press the operation part 121 after lifting the finger to rotate the motor 14, so that unlocking and rotation of the motor 14 are controlled to be more convenient, and user experience is improved.
Further, the motor 14 can rotate after unlocking, 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 rotation speed of the motor 14 according to the speed regulating signal received by the speed regulating element 123, so that the motor 14 is prevented from being started accidentally due to any electronic element fault in the circuit, and the safety performance of the driving component 10 is improved.
Thus, the user can unlock the motor 14 and rotate the motor at a speed by touching and/or pressing the operation part 121, which is convenient for the user to operate with one hand and improves the user experience.
In some real-time modes, the drive unit 10 includes a body 11, a trigger device 12 is provided on the body 11, and a motor 14 and a control device 13 are located within the body 11.
The body 11 is generally cylindrical. The body 11 may be made of plastic and/or metal materials. The body 11 can protect the control device 13, the motor 14 and other internal parts from damage. The body 11 may be a watertight seal, 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 similar to the surface of the machine body 11 in height, so that the product is more attractive, the pressing stroke of the speed regulating element 123 can be greatly reduced (the pressing stroke can be smaller than 1 mm), the rotating speed of the one-key micro-stroke control motor 14 can be easily realized by a user, and the user experience is improved.
In certain embodiments, unlocking element 122 comprises a touch sensor or a push switch, and governor element 123 comprises at least one of a pressure sensor, potentiometer, and 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 the capacitance data to the control device 13, and the control device 13 receives the capacitance data and then unlocks the motor 14. Of course, the unlocking element 122 may not only be a capacitive element, but may be a different element 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 the pressure signal, convert the pressure signal into a usable 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 comprises 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 movable 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 is controlled to rotate 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 operate the unlocking element with one key. It will be appreciated that the unlocking element 122 may not only be located inside the operating portion 121, but may be located at different positions according to different needs.
In certain embodiments, unlocking element 122 is located between operating portion 121 and governor element 123. Alternatively, the operating unit 121, the unlocking element 122, and the governor element 123 are provided in this order along the outside of the body 11 toward the inside of the body 11. This arrangement results in a more compact construction of the triggering device 12.
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 speed regulating element 123, the force transmitting element 124 being configured to transmit the pressure of the speed regulating operation to the speed regulating element 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 to feed back 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 member 124 is rod-shaped and extends through the unlocking member 122.
The rod-shaped force transmitting member 124 facilitates the force transmitting member 124 to transmit the pressure of the speed regulating operation to the speed regulating member 123. Of course, the force transmission element 124 may not only be rod-shaped, but may take different shapes according to different circumstances, for example, the force transmission element 124 may be block-shaped.
In certain embodiments, the triggering device 12 includes a resilient element 15 disposed between the force transmitting element 124 and the governor element 123.
The arrangement of the elastic element 15 can form a buffering period between the force transmission element 124 and the speed regulating element 123, so that the hand feeling of the 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, silica gel, rubber, metal spring, or other materials, or the elastic element 15 may be made of other elastic structures.
In some embodiments, the elastic member 15 may be disposed at an end of the force transmitting member 124 facing the speed regulating member 123, and the elastic member 15 may be disposed at a side of the speed regulating member 123 facing the force transmitting member 124. In addition, the elastic element 15 may be disposed at both the end of the force transmission element 124 facing the speed adjusting element 123 and the side of the speed adjusting element 123 facing the force transmission element 124, and the hand feeling of the user pressing the operation part 121 may be increased by the elastic element 15, so as to improve the user experience.
In some embodiments, the control device 13 includes a circuit board 131 and a processor 132, and the speed regulating 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 regulating signal.
The arrangement of the circuit board 131 and the processor 132 enables the driving part 10 to better control the state of the motor 14, so that the working efficiency of the motor 14 is higher.
Specifically, the circuit board 131 may be a rigid printed circuit board 131, and of course, the circuit board 131 may not only be a rigid printed circuit board 131, but a circuit board 131 may be omitted depending on the circumstances, for example, a flexible circuit board 131 may be employed for the circuit board 131.
In some embodiments, the speed regulating 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 rotational speed of the motor 14 according to the current pressure, where the rotational speed of the motor 14 is in positive correlation with the pressure generated by pressing the operation portion 121.
The rotational speed of the motor 14 increases as the current pressure magnitude increases, and the rotational speed of the motor 14 decreases as the current pressure magnitude decreases. So can make the rotational speed of motor 14 along with the change of current pressure size and change, the user wants the rotational speed to press operating portion 121 a bit more and then press operating portion 121 a bit more and slightly, and the operation is very convenient, and the convenience of customers controls the rotational speed of motor 14, promotes user experience.
In some embodiments, the control device 13 presets a correspondence relationship between the pressure segment and the rotation speed, the greater the pressure of the pressure segment, the greater the rotation speed of the corresponding motor 14. The processor 132 is configured to determine a pressure segment in which the current pressure is located, and control the rotational speed of the motor 14 according to the pressure segment in which the current pressure is located and the correspondence.
The provision of the pressure section can make it easier to form a perfect match between the rotational speed of the motor 14 and the current pressure level, thereby making the rotational speed of the motor 14 more stable and making the rotation of the motor 14 more efficient. The processor 132 can match the current pressure and the pressure section, and control the motor 14 to rotate according to the corresponding rotation speed according to the rotation speed of the corresponding motor 14 of the pressure section where the current pressure is located, so that the situation that the current pressure and the pressure section are not matched does not occur, and the rotation efficiency of the motor 14 is improved.
In certain embodiments, the processor 132 is configured to calibrate the governor element 123 based on the pressure of the governor operation prior to unlocking the motor 14.
Since a certain pressure may occur when the user's finger touches the operation part 121, the pressure needs to be calibrated, and errors can be prevented after the calibration, so that the rotation speed and the pressure of the motor 14 can be better matched.
Specifically, the user touches the operation portion 121 with a finger, the operation portion 121 recognizes that the touch operation is generated as an unlock operation at this time, and feeds back the unlock operation to the control device 13. When the control device 13 receives the unlocking operation and unlocks the motor 14, the speed regulating element 123 acquires an initial pressure R0 and feeds the initial pressure R0 back to the processor 132, the processor 132 records a rotation speed N0 corresponding to the initial pressure R0 as 0, so that the processor 132 controls the motor 14 not to rotate, when the current magnitude R1 of the pressure of the speed regulating operation acquired by the speed regulating element 123 is greater than the initial pressure R0, the processor 132 controls the motor 14 to rotate, and when the current magnitude R2 of the pressure of the speed regulating operation acquired by the speed regulating element 123 is less than the initial pressure R0, the processor 132 controls the motor 14 to stop rotating, so that the controllability of the rotation speed of the motor 14 is better.
Specifically, the processor 132 sets the minimum pressure RL of the rotation of the motor 14 after the calibration of the speed adjusting element 123, wherein the minimum pressure RL is greater than the initial pressure R0, that is, RL > R0, only when the current magnitude of the pressure of the speed adjusting operation R1 is greater than or equal to the minimum pressure RL, that is, R1 is greater than or equal to RL, the motor 14 can rotate, and when the current magnitude of the pressure of the speed adjusting operation R1 is less than the minimum pressure RL, that is, R1< RL, the motor 14 does not rotate, so that a reaction time can be given to the user, a situation that the user rotates slightly with the motor 14 does not occur, and the user experience is improved.
For example, assuming that the initial pressure R0 is 50Ω, assuming that the lowest pressure RL is 60, that is, rl=r0+10Ω, when the current magnitude of the pressure R1 of the speed adjusting operation is 55Ω, the processor 132 controls the motor 14 not to rotate because R1< RL, and when the current magnitude of the pressure R1 of the speed adjusting operation is 60deg.Ω, the processor 132 controls the motor 14 to rotate because R1> RL.
Specifically, the processor 132 sets rotational speed gears when calibrating the speed adjusting element 123, different rotational speed gears correspond to different pressure segments, and when the current magnitude of the pressure of the speed adjusting operation falls into the different pressure segments, the rotational speed of the motor 14 rotates according to the rotational speed of the corresponding pressure segment. Wherein, the different rotational speed gears correspond to different pressure segments, which means that after the processor 132 calibrates the speed adjusting element 123, a plurality of pressure segments are set based on the minimum pressure RL, the different rotational speeds correspond to different rotational speeds, and the greater the pressure of the pressure segments, the greater the rotational speed of the corresponding motor 14.
Assuming that there are N (N is not less than 0, N is a natural number) gears, which are the 0 th, 1 st, 2 nd and 3 rd … … nth gears, respectively, wherein the 0 th gear refers to the current magnitude R1 of the pressure of the speed regulating operation is smaller than the minimum pressure RL, and because R1< RL, the processor 132 controls the motor 14 not to rotate, at this time, in the 0 th gear, the rotation speed of the motor 14 is 0rmp, and the first pressure segment refers to the pressure range of 0< R1< RL.

Gear 2 refers to the current magnitude of the pressure of the speed regulating operation R1 being greater than or equal to the 1 st gear pressure RL1 and being smaller than the 2 nd gear pressure RL2, wherein the 2 nd gear pressure RL2>1 st gear pressure RL1, that is, in gear 2, RL1 is less than or equal to R1< RL2, at this time, the rotation speed of the motor 14 is set to be P1 (wherein P1> P), and the third pressure section refers to the pressure range of RL1 is less than or equal to R1< RL 2. The 3 rd gear refers to the current magnitude of the pressure of the speed regulating operation R1 being greater than or equal to the 2 nd gear pressure RL2 and being smaller than the 3 rd gear pressure RL3, wherein the 3 rd gear pressure RL3>2 nd gear pressure RL2, that is, in the 3 rd gear, RL2 is less than or equal to R1< RL3, at this time, the rotation speed of the motor 14 is set to P2 (wherein P2> P1), and the fourth pressure section refers to the pressure range of RL2 is less than or equal to R1< RL 3. Similarly, the nth gear refers to the current magnitude of the pressure R1 of the speed adjusting operation being equal to or greater than the (N-1) gear pressure RL (N-1) and being smaller than the N gear pressure RLN, wherein the N gear pressure RLN > (N-1) gear pressure RL (N-1), that is, when RL (N-1) +.r1 < RLN, in the nth gear, the rotational speed of the motor 14 is set to be P (N-1) (where P (N-1) > P (N-2)), and the (n+1) th stage pressure section refers to the pressure range RL (N-1) +.r1 < RLN.
In one embodiment, referring to FIG. 4, 9 gear positions are assumed, namely, 0 th, 1 st, 2 nd, 3 rd, 4 th, 5 th, 6 th, 7 th, 8 th, 9 th, and the lowest pressure RL is 60 Ω, the 1 st gear pressure RL1 is 70 Ω, the 2 nd gear pressure RL2 is 80 Ω, the 3 rd gear pressure RL3 is 90 Ω, the 4 th gear pressure RL4 is 100 Ω, the 5 th gear pressure RL5 is 110 Ω, the 6 th gear pressure RL6 is 120 Ω, the 7 th gear pressure RL7 is 130 Ω, the 8 th gear pressure RL8 is 140 Ω, and the 9 th gear pressure RL9 is 150 Ω, at this time, the pressure range of the first pressure section is 0Ω < r1<60 Ω, the pressure range of the second pressure section is 60deg.OMEGA.ltoreq.r1 <70Ω, the pressure range of the third pressure section is 70Ω.ltoreq.r1 <80 Ω, the pressure range of the fourth pressure section is 80Ω.ltoreq.r1 <90 Ω, the pressure range of the fifth pressure section is 90Ω.ltoreq.r1 <100 Ω, the pressure range of the sixth pressure section is 100deg.OMEGA.ltoreq.r1 <110 Ω, the pressure range of the seventh pressure section is 110Ω.ltoreq.r1 <120 Ω, the pressure range of the eighth pressure section is 120Ω.ltoreq.r1 <130 Ω, the pressure range of the ninth pressure section is 130Ω.ltoreq.r1 <140 Ω, and the pressure range of the tenth pressure section is 140Ω.ltoreq.r1 <150 Ω. Wherein the first pressure section corresponds to gear 0, wherein the second pressure section corresponds to gear 1, wherein the third pressure section corresponds to gear 2, wherein the fourth pressure section corresponds to gear 3, wherein the fifth pressure section corresponds to gear 4, wherein the sixth pressure section corresponds to gear 5, wherein the seventh pressure section corresponds to gear 6, wherein the eighth pressure section corresponds to gear 7, wherein the ninth pressure section corresponds to gear 8, wherein the tenth pressure section corresponds to gear 9.
It is assumed that the rotational speed of the motor 14 corresponding to the 0 th gear is 0rmp, the rotational speed of the motor 14 corresponding to the 1 st gear is 5000rmp, the rotational speed of the motor 14 corresponding to the 2 nd gear is 5500rmp, the rotational speed of the motor 14 corresponding to the 3 rd gear is 6000rmp, the rotational speed of the motor 14 corresponding to the 4 th gear is 6500rmp, the rotational speed of the motor 14 corresponding to the 5 th gear is 7000rmp, the rotational speed of the motor 14 corresponding to the 6 th gear is 7500rmp, the rotational speed of the motor 14 corresponding to the 7 th gear is 8000rmp, the rotational speed of the motor 14 corresponding to the 8 th gear is 8500rmp, and the rotational speed of the motor 14 corresponding to the 9 th gear is 9000rmp. In this way, the current magnitude R1 of the pressure according to the speed regulation operation falls into different pressure segments, and the processor 132 controls the motor 14 to rotate at the corresponding rotation speed according to the rotation speed corresponding to the corresponding pressure segment. For example, the current magnitude of the pressure of the governor operation R1 is 125Ω, and the current magnitude of the pressure of the governor operation R1 is located in the eighth pressure segment, i.e., the 7 th gear, so the processor 132 controls the motor 14 to rotate at the rotational speed corresponding to the 7 th gear, i.e., the rotational speed of the motor 14 is 8000rmp.
Of course, the number of gears is not only 9, but also different gears can be adopted according to different requirements, for example, the number of gears can be 2, 3, 13, 15 and the like, and the gears can be divided according to actual situations. The more gears, the smoother the change in rotational speed of the motor 14, the closer to a continuously variable transmission. The fewer the number of gears, the more pronounced the change in rotational speed of the motor 14.
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 the time when the current magnitude RL of the pressure of the speed regulation operation reaches the highest pressure RH. That is, when R1. Gtoreq.RH, the rotational speed is rotated according to the rotational speed corresponding to the highest pressure RH.

Assuming a maximum pressure RH of 160Ω, and therefore a pressure range of 150+.R1 <160Ω for the eleventh pressure segment, the current magnitude of the pressure R1 for the governor operation is still less than the maximum pressure RH, and therefore the processor 132 will control the motor 14 to rotate at a speed of 10 th gear, with a corresponding speed of 9500rmp for the motor 14. When the current magnitude of the pressure R1 of the speed-adjusting operation is greater than or equal to the highest pressure RH, that is, R1 is greater than or equal to RH, at this time, the 11 th gear is the 11 th gear, the rotation speed of the 11 th gear is 10000rmp, and the twelfth pressure section is R1 is greater than or equal to RH, that is, when the current magnitude of the pressure R1 of the speed-adjusting operation exceeds the highest pressure RH, the processor 132 controls the motor 14 to rotate at the rotation speed of the motor 14 corresponding to the 11 th gear. For example, the current magnitude R1 of the pressure of the speed adjusting operation is 170Ω, the pressure range is 170Ω >160Ω, that is, the current magnitude R1 of the pressure of the speed adjusting operation is greater than the highest pressure RH, and the processor 132 controls the motor 14 to rotate at the rotational speed of the motor 14 corresponding to the 11 th gear. For another example, the current magnitude of the pressure R1 of the speed adjusting operation is 180Ω, the pressure range is 180Ω >160Ω, that is, the current magnitude of the pressure R1 of the speed adjusting operation is greater than the highest pressure RH, and the processor 132 controls the motor 14 to rotate at the rotational speed of the motor 14 corresponding to the 11 th gear.
In certain embodiments, the processor 132 is configured to unlock the motor 14 after the unlocking element 122 receives an unlocking operation for a predetermined period of time.
By the arrangement, risks brought by misoperation of a user can be effectively reduced.
If the user is taking up the drive member 10 and erroneously touching the triggering device 12, this may lead to an unnecessary risk if the motor 14 is momentarily turned at this time. For example, a child may take the drive member 10 to play, but may not want to use it, however, as soon as the drive member 10 is taken, the motor 14 is rotating, potentially injuring the child. 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 performance of the driving part 10.
Wherein the predetermined period of time may be 3 seconds, or 4 seconds, or 5 seconds. The user needs to maintain the unlocking operation after a predetermined period of time for the processor 132 to unlock the motor 14.

The processor 132 can match the current pressure and the pressure section, and control the motor 14 to rotate according to the corresponding rotation speed according to the rotation speed of the corresponding motor 14 of the pressure section where the current pressure is located, so that the situation that the current pressure and the pressure section are not matched does not occur, and the rotation efficiency of the motor 14 is improved.
In some embodiments, unlocking the motor 14 of the drive component 10 according to an unlocking signal generated by the triggering device 12 of the drive component 10 includes:
the motor 14 is unlocked after a predetermined period of time after the unlocking element 122 of the triggering device 12 generates the unlocking signal.
Since a certain pressure may occur when the user's finger touches the operation part 121, the pressure needs to be calibrated, and errors can be prevented after the calibration, so that the rotation speed and the pressure of the motor 14 can be better matched.
Specifically, the user touches the operation portion 121 with a finger, the operation portion 121 recognizes that the touch operation is generated as an unlock operation at this time, and feeds back the unlock operation to the control device 13. When the control device 13 receives the unlocking operation and unlocks the motor 14, the speed regulating element 123 acquires an initial pressure R0 and feeds the initial pressure R0 back to the processor 132, the processor 132 records a rotation speed N0 corresponding to the initial pressure R0 as 0, so that the processor 132 controls the motor 14 not to rotate, when the current magnitude R1 of the pressure of the speed regulating operation acquired by the speed regulating element 123 is greater than the initial pressure R0, the processor 132 controls the motor 14 to rotate, and when the current magnitude R2 of the pressure of the speed regulating operation acquired by the speed regulating element 123 is less than the initial pressure R0, the processor 132 controls the motor 14 to stop rotating, so that the controllability of the rotation speed of the motor 14 is better.
Specifically, the processor 132 sets the minimum pressure RL of the rotation of the motor 14 after the calibration of the speed adjusting element 123, wherein the minimum pressure RL is greater than the initial pressure R0, that is, RL > R0, only when the current magnitude of the pressure of the speed adjusting operation R1 is greater than or equal to the minimum pressure RL, that is, R1 is greater than or equal to RL, the motor 14 can rotate, and when the current magnitude of the pressure of the speed adjusting operation R1 is less than the minimum pressure RL, that is, R1< RL, the motor 14 does not rotate, so that a reaction time can be given to the user, a situation that the user rotates slightly with the motor 14 does not occur, and the user experience is improved.
For example, assuming that the initial pressure R0 is 50Ω, assuming that the lowest pressure RL is 60, that is, rl=r0+10Ω, when the current magnitude of the pressure R1 of the speed adjusting operation is 55Ω, the processor 132 controls the motor 14 not to rotate because R1< RL, and when the current magnitude of the pressure R1 of the speed adjusting operation is 60deg.Ω, the processor 132 controls the motor 14 to rotate because R1> RL.

It is assumed that the rotational speed of the motor 14 corresponding to the 0 th gear is 0rmp, the rotational speed of the motor 14 corresponding to the 1 st gear is 5000rmp, the rotational speed of the motor 14 corresponding to the 2 nd gear is 5500rmp, the rotational speed of the motor 14 corresponding to the 3 rd gear is 6000rmp, the rotational speed of the motor 14 corresponding to the 4 th gear is 6500rmp, the rotational speed of the motor 14 corresponding to the 5 th gear is 7000rmp, the rotational speed of the motor 14 corresponding to the 6 th gear is 7500rmp, the rotational speed of the motor 14 corresponding to the 7 th gear is 8000rmp, the rotational speed of the motor 14 corresponding to the 8 th gear is 8500rmp, and the rotational speed of the motor 14 corresponding to the 9 th gear is 9000rmp. In this way, the current magnitude R1 of the pressure according to the speed regulation operation falls into different pressure segments, and the processor 132 controls the motor 14 to rotate at the corresponding rotation speed according to the rotation speed corresponding to the corresponding pressure segment. For example, the current magnitude of the pressure of the governor operation R1 is 125Ω, and the current magnitude of the pressure of the governor operation R1 is located in the eighth pressure segment, i.e., the 7 th gear, so the processor 132 controls the motor 14 to rotate at the rotational speed corresponding to the 7 th gear, i.e., the rotational speed of the motor 14 is 8000rmp.

Referring to fig. 6, in another example, taking the above numerical example, it is assumed that there are 11 gears, that is, the 9-gear pressure RL9 is 150Ω, the pressure range of the tenth pressure section is 140Ω+.ltoreq.r1 <150Ω, and the rotational speed of the motor 14 corresponding to the 9 th gear is 9000rmp. Assuming a maximum pressure RH of 160Ω, and therefore a pressure range of 150+.R1 <160Ω for the eleventh pressure segment, the current magnitude of the pressure R1 for the governor operation is still less than the maximum pressure RH, and therefore the processor 132 will control the motor 14 to rotate at a speed of 10 th gear, with a corresponding speed of 9500rmp for the motor 14. When the current magnitude of the pressure R1 of the speed-adjusting operation is greater than or equal to the highest pressure RH, that is, R1 is greater than or equal to RH, at this time, the 11 th gear is the 11 th gear, the rotation speed of the 11 th gear is 10000rmp, and the twelfth pressure section is R1 is greater than or equal to RH, that is, when the current magnitude of the pressure R1 of the speed-adjusting operation exceeds the highest pressure RH, the processor 132 controls the motor 14 to rotate at the rotation speed of the motor 14 corresponding to the 11 th gear. For example, the current magnitude R1 of the pressure of the speed adjusting operation is 170Ω, the pressure range is 170Ω >160Ω, that is, the current magnitude R1 of the pressure of the speed adjusting operation is greater than the highest pressure RH, and the processor 132 controls the motor 14 to rotate at the rotational speed of the motor 14 corresponding to the 11 th gear. For another example, the current magnitude of the pressure R1 of the speed adjusting operation is 180Ω, the pressure range is 180Ω >160Ω, that is, the current magnitude of the pressure R1 of the speed adjusting operation is greater than the highest pressure RH, and the processor 132 controls the motor 14 to rotate at the rotational speed of the motor 14 corresponding to the 11 th gear.
