For example, the air conditioner controls the wind direction of the air outlet by controlling the rotation of the swing blades at the air outlet through the motor. Or the tower fan controls the wind direction of the air outlet by controlling the rotation of the swing blades arranged on the air outlet. And then household appliances such as a humidifier or a dehumidifier control the wind direction of the air outlet or the air inlet through the swing blades.
In order to precisely control the wind direction of the air outlet, the rotation angle of the swing blade needs to be controlled, and the rotation angle of the swing blade is controlled by a motor. Thus, precisely controlling the rotation of the motor becomes a key to controlling the wind direction. However, the motor is easy to generate small errors in the rotation process, and single errors do not greatly influence the wind direction, but in the long-time use process, the running errors of the motor are gradually accumulated, so that the rotation angle of the swing blade is deviated from the target angle, the wind direction is not consistent with the target wind direction, and the accuracy of the wind direction is influenced.
For example, the motor accumulates a certain amount of running error under long-term rotation, specifically reflected on the swing blade, accumulating 5 ° of running error. The current angle of the swing blade is 25 degrees, the system actually displays that the angle of the swing blade is 30 degrees, the system needs to control the swing blade to rotate to a target angle of 60 degrees, and the system calculates the angle of 30 degrees at which the swing blade needs to rotate; however, when the system controls the motor to drive the swing blade to actually rotate for 30 degrees, the angle of the swing blade is 55 degrees, and the angle is different from the target angle by 5 degrees, so that the actual angle of the wind direction of the wind is different from the target angle, and the accuracy of the wind direction is affected.

This variant will be known to the person skilled in the art.
The application provides a swing blade calibration method, by which the angle of a swing blade can be calibrated, and the operation error of the swing blade caused by the operation error of a motor is eliminated by controlling the operation of the swing blade to a calibration position, so that the angle of the swing blade at an air outlet is conveniently and accurately controlled, and the wind direction of air outlet is further controlled.
In the present application, the vane calibration method is implemented based on a vane device, and referring to fig. 1 and 2, the vane device includes a control unit 110, a motor 120, a vane 130, and a limiting component, where the control unit 110 is used to control the motor 120 to work, and an output shaft of the motor 120 is connected to the vane 130. Preferably, the motor 120 is a stepper motor. The swing blade 130 is a strip-shaped plate.
In one embodiment, a transmission mechanism is disposed between the motor 120 and the swing blade 130, an output shaft of the motor 120 is connected to the transmission mechanism, and the transmission mechanism is connected to the swing blade 130. Preferably, the transmission mechanism is a gear transmission mechanism.
The first calibration position and the second calibration position are used for limiting the movement stroke of the swing blade 130, and the swing blade 130 rotates between the first calibration position and the second calibration position. The limiting assembly comprises a first limiting structure 150 and a second limiting structure 160, the first limiting structure 150 is arranged on a first calibration position, the second limiting structure 160 is arranged on a second calibration position, and the first calibration position and the second calibration position take a fixed point as a circle center, so that a sector-shaped calibration space is formed among the fixed point, the first calibration position and the second calibration position. In one embodiment, the first calibration bit and the second calibration bit are straight lines, the first calibration bit and the second calibration bit may extend to a fixed point, and the first calibration bit and the second calibration bit may intersect at the fixed point. In another embodiment, the first calibration bit and the second calibration bit are points disposed in the calibration space.
The swing blade 130 also rotates around the fixed point with the fixed point as the center, and the swing blade 130 rotates between the first calibration position and the second calibration position. Specifically, the first end of the swing blade 130 passes through the fixed point, the second end of the swing blade 130 extends into the calibration space, and the swing blade 130 rotates in the calibration space around the center of the circle under the driving of the motor 120. Because the first limiting structure 150 is disposed on the first calibration position, the second limiting structure 160 is disposed on the second calibration position, and when the swing blade 130 rotates to the first calibration position, the swing blade 130 will be blocked by the first limiting structure 150 and cannot rotate further in the direction of the first calibration position; when the swing blade 130 rotates to the second calibration position, the swing blade 130 is blocked by the second limiting structure 160 and cannot further rotate toward the second calibration position. In one embodiment, the first calibration bit and the second calibration bit are at an angle of 0 ° to 360 ° with respect to the fixed point. Preferably, the first calibration bit and the second calibration bit are at an angle of 0 ° to 180 ° with respect to the fixed point.

The first reference position and the second reference position take a fixed point as a circle center to form a sector-shaped reference space, and the reference space is arranged in the calibration space. The third reference position is arranged at any position of the reference space. Preferably, the third reference bit is disposed at a central position between the first reference bit and the second reference bit.
The first calibration bit and the first reference bit are arranged at a first angle relative to the fixed point, and the second calibration bit and the second reference bit are arranged at a second angle. In one embodiment, the first angle is between 1 and 60 ° and the second angle is between 1 and 60 °.
In actual operation, the swing blade 130 actually works in the reference space, when a certain amount of operation error is accumulated during long-time operation of the motor 120, the control unit 110 drives the motor 120 to drive the swing blade 130 to operate to the first calibration position or the second calibration position, and eliminates the operation error of the swing blade 130 caused by the operation error of the motor 120, so that the swing blade 130 is driven to enter the reference space to operate after the first calibration position and the second calibration position are calibrated.
The reference space is disposed in the calibration space, and the first calibration position is not coincident with the first reference position, and the second calibration position is not coincident with the second reference position, so that the swing blade 130 does not operate to the first calibration position or the second calibration position in the working mode, and the swing blade 130 is prevented from abutting against the first limiting structure 150 and the second limiting structure 160, so that the motor 120 idles and is damaged.
In one embodiment, the swing blade device is a swing mechanism of an air conditioner, the swing blade 130 of the swing blade device is a swing blade on an air outlet of an air conditioner indoor unit, and the first calibration position and the second calibration position are respectively disposed at two ends of the air outlet, that is, the first limit structure 150 and the second limit structure 160 are two side walls of the air outlet. The control unit 110 controls the motor 120 to drive the swing blade 130 to operate to the first calibration position and the second calibration position, so as to calibrate the swing blade 130 and eliminate operation errors, thereby being convenient for well controlling the wind direction of the air outlet of the air conditioner.
In another embodiment, the swing blade apparatus is a swing head mechanism of a tower fan. The swing blade 130 of the swing blade device is a rotating blade of the tower fan, which is arranged on the air outlet, and the wind direction of the air outlet is controlled by controlling the relative angle relation between the rotating blade and the air outlet.
In an exemplary embodiment of the present application, in conjunction with fig. 3, the swing blade calibration method includes the following specific steps:
step S11, receiving a calibration instruction, and entering a calibration state:
the external device outputs a calibration instruction to the control unit, and the control unit receives the calibration instruction output by the external device and enters a calibration state. In one embodiment, the external device outputs the calibration instruction to the control unit when the swing blade apparatus is started. And after the preset time length after the leaf swinging device outputs the calibration instruction to the control unit last time, for example, the preset time length is 30min, the external device outputs the calibration instruction to the control unit again, and the external device is continuously circulated, so that the leaf swinging device can be automatically calibrated after long-time operation, and errors of the leaf swinging device after long-time operation can be avoided. In another embodiment, the control unit may generate the calibration command by itself after controlling the motor to operate for a fixed time.
Step S12, controlling the motor to drive the swing blade to move towards the first calibration position for a first period of time at a first rotation speed, so that the swing She Yun moves to the first calibration position, and the swing blade rotates in a calibration space defined by the first calibration position and the second calibration position with the fixed point as a center of a circle:
the motor drives the swing blade to run in the reference space, and the control unit enters a calibration state after receiving a calibration instruction. The control unit controls the motor to rotate at a first rotation speed, so that the swing blade is driven to move in a direction of a first calibration position at the first speed, the swing blade spans a first reference position under the drive of the motor, the swing blade moves to the first calibration position, and the swing blade stops rotating under the limit of a first limit structure arranged on the first calibration position.
Furthermore, the control unit controls the motor to run at a first rotational speed for a first period of time having a large time margin, so that the swing blade can run at any position in the reference space to the first calibration position. For example, if the swing blade is at the second reference position, the time from the second reference position to the first calibration position at the first speed is the first time length or less, so that the swing blade has enough time to travel to the first calibration position, and further, the operation error of the swing blade is eliminated.
When the time from the swinging She Yun to the first calibration position is less than the first time length, the residual time is left, the swinging leaves have moment for continuing to rotate towards the first calibration position, but under the limit of the first limit structure, the swinging leaves stop running, and the motor idles. When the motor runs for a first time, the control unit controls the motor to stop rotating.
In one embodiment, the control unit controls the motor to drive the pendulum She Yun to the second calibration position, so as to eliminate the operation error of the pendulum blade.
In one embodiment, the first rotation speed is variable speed, specifically, the first time period is divided into three time periods, the first rotation speed rotates at a first sub-rotation speed in the first time period, rotates at a second sub-rotation speed in the second time period, and rotates at a third sub-rotation speed in the third time period. In this embodiment, the first sub-rotation speed is smaller than the second sub-rotation speed, and the second sub-rotation speed is smaller than the third sub-rotation speed, so that the swing blade gradually increases from the first sub-rotation speed to the third sub-rotation speed in three time periods of the first time period, thereby ensuring that the motor does not step out, and simultaneously running to the first calibration position or the second calibration position at a faster speed, and improving user experience.
In one embodiment, in conjunction with fig. 4, the step S12 further includes the following steps:
step S121, when the pendulum She Yun moves to the first calibration position, triggering the travel switch disposed on the first calibration position, so that the travel switch outputs a calibration signal:
the swing blade device further comprises a travel switch, and the travel switch is electrically connected with the control unit. In fig. 1 and fig. 2, a first travel switch 170 is disposed on the first calibration position, and a second travel switch 180 is disposed on the second calibration position. The motor drives the pendulum She Yun to move to the first calibration position, and triggers the first travel switch 170, so that the first travel switch 170 outputs a calibration signal to the control unit. In another embodiment, the travel switch may be replaced with a photoelectric switch.
Step S122, receiving the calibration signal, and driving the motor to change the rotation direction:
after the control unit receives the calibration signal, if the motor does not run for a first time period at a first rotating speed, the control unit also drives the motor to stop rotating, so that the motor is prevented from idling and being damaged when the motor runs to a first calibration position and is limited by a first limiting structure.
The control unit then drives the motor to rotate in a direction opposite to the first rotational speed in preparation for the next operation of the pendulum blade to the first reference position or the second reference position or the third reference position by driving the pendulum blade.
Step S13, controlling the motor to drive the pendulum She Yunhang at the second rotation speed for a second period of time, so that the pendulum leaf moves to a preset first reference position or second reference position or third reference position, wherein a reference space defined by the first reference position and the second reference position is arranged in the calibration space, the first reference position is close to the first calibration position, the second reference position is close to the second calibration position, and the third reference position is arranged in the reference space:
when the swing blade is driven by the motor to run to the first calibration position, the running error before the swing blade is eliminated, and then the control unit controls the motor to drive the swing blade to run to the reference space at the second rotating speed, and the swing blade is enabled to run to the first reference position, the second reference position or the third reference position so as to calibrate the swing blade.
Specifically, the control unit controls the motor to rotate at the second rotation speed, and controls the motor to operate for a second period of time, and after the motor operates for the second period of time, the motor drives the pendulum She Yun to move to the first reference position, the second reference position or the third reference position so as to calibrate the pendulum leaf. When the swing blade is positioned at the first reference position or the second reference position or the third reference position, the control unit stores information when the swing blade is positioned at the first reference position or the second reference position or the third reference position in the storage unit, so that when the swing blade is required to be controlled to move to the first movement position, the angle required by the swing blade when the swing blade moves from the first reference position or the second reference position or the third reference position to the first movement position is calculated. The first motion bit is any position between the first reference bit and the second reference bit.
For example, the first reference position is 0 °, the second reference position is 60 °, the third reference position is 30 °, the first calibration position is at an angle of-1 °, and the second calibration position is at an angle of 61 °. The control unit controls the motor to rotate for a second time period at a second rotating speed, so that the motor drives the swinging blade to move from the first calibration position to the first reference position, and the motor drives the swinging She Yun to perform 1 degree. Then, the swing blade device needs to drive the swing blade to run to a first movement position at 45 degrees, the control unit calculates that the difference angle between the first reference position and the first movement position is 45 degrees, and the motor is controlled to drive the swing She Yunhang for a third duration at a third rotating speed, so that the swing blade runs from the first reference position to a fourth calibration position.
Step S14, receiving a working instruction, exiting the calibration state, entering the working state, and driving the swing blade to rotate in the reference space by the driving motor:
after the blade swinging device finishes calibration, when the working instruction output by the external equipment is received, the blade swinging device exits the calibration state and enters the working state. The control unit receives a rotation signal output by external equipment, acquires a target angle represented by the rotation signal, calculates a difference angle between the target angle and a current reference position of the swing blade, calculates the rotating speed and the rotating time length of a corresponding motor, and controls the motor to drive the swing blade to move from the current reference position to the position of the target angle.
In one embodiment, the control unit outputs a first signal to the external device after calibration is completed, and the external device obtains information that the blade swinging device completes calibration by analyzing the first signal after receiving the first signal.
In one embodiment, in conjunction with fig. 5, before the step S12, the step S11 further includes the following steps:
step S111, controlling a direction sensor to detect the running direction of the swing blade, and obtaining a direction signal:
referring to fig. 2, the control unit is further electrically connected to the direction sensor 140, and after the control unit controls the motor to drive the swing blade to operate, the direction sensor 140 is controlled to detect the operation direction of the swing blade. The swing blade generally rotates in a horizontal space or a vertical space, and the direction sensor 140 acquires a direction signal indicating the rotation direction of the swing blade by detecting the rotation of the swing blade. Preferably, the direction sensor 140 is a triaxial acceleration sensor.
Step S112, based on the direction signal, entering a different calibration mode:
after the control unit receives the direction signal, the direction signal is analyzed to obtain the rotation direction information, and different calibration modes are entered. Referring specifically to fig. 6, the following steps are provided:
step S1121, when the direction signal characterizes the horizontal rotation direction, entering a first calibration mode:
when the control unit analyzes and acquires the horizontal rotation direction information from the direction signal, the control unit enters a first calibration mode.
Step S1122, when the direction signal indicates the vertical rotation direction, entering a second calibration mode:
when the control unit analyzes the direction signal to obtain the vertical rotation direction information, the control unit enters a second calibration mode. The rotational speeds of the motors between the first calibration mode and the second calibration mode are different.
In one embodiment, in conjunction with fig. 7, the steps S11 further include the preceding steps S101 and S102, where an error may occur in the swing blade after the motor is operated for a predetermined period of time, and the operation error is eliminated by recalibrating the swing blade after the predetermined period of time. Specifically, the method comprises the following steps:
step S101, after the motor is controlled to work for a preset time, outputting a time signal to the outside:
the control unit starts timing after driving the motor to work, and when the motor works for a preset time, the swing blade may have a running error, so the control unit generates a time signal after the motor works for a preset time, and the control unit outputs the generated time signal to the external equipment. Preferably, the preset time period is set to 10 minutes.
Step S102, receiving a calibration instruction issued by the external device in response to the time signal:
after the external equipment receives the time signal output by the control unit, the external equipment generates the calibration instruction according to the time signal, and the external equipment transmits the calibration instruction to the control unit so as to drive the control unit to calibrate the swing blade device through the calibration instruction.
In another embodiment, the swing blade device is further provided with a detection component, the detection component detects the operation error of the swing blade, when the detection component detects that the swing blade has the operation error, the detection component outputs a detection signal to the control unit, the control unit outputs the detection signal to the external device, and the external device issues a calibration instruction to the control unit to calibrate the swing blade, so that the operation error is eliminated.
In this embodiment, the detection component is an infrared sensor, and a first detection position is disposed in the reference space corresponding to an emission path of infrared rays emitted by the infrared sensor. When the pendulum She Yun moves to the first detection position, the infrared ray is pendulum She Zudang, and the infrared sensor correspondingly generates a first detection signal; when the swing blade does not operate to the first detection position, the infrared sensor correspondingly generates a second detection signal. In this embodiment, the detecting means may be any one of a laser sensor, an ultrasonic sensor, a radar sensor, and a photoelectric sensor.
Specifically, in connection with fig. 8, the method further includes a pre-step S103, a step S104, and a step S105 before the step S11.
