According to an embodiment of the invention, a control method of a flip cover driving device is provided, and the control method is used for controlling the flip cover driving device to operate so as to drive a drum cover to turn over relative to a drum body, so as to open or close the drum body. Wherein, flip drive arrangement includes the motor, and the motor can drive the bung and for the staving upset, and the rotational speed of motor and the rotational speed of bung become positive correlation, and the rotational speed of motor is higher then the upset speed of bung is faster, otherwise, the rotational speed of motor is slower then the upset speed of bung is slower.

In this embodiment, as shown in fig. 1, the control method includes the following steps:

step S101: acquiring a real-time included angle between the barrel cover and the barrel body according to the opening and closing state of the barrel cover;

step S102: and controlling the rotating speed of the motor and the rotating speed of a real-time switch of the barrel cover according to the real-time included angle.

Specifically, in step S101, a real-time included angle between the barrel body and the barrel cover is a real-time included angle between the barrel cover and the upper surface of the barrel body during the opening process of the barrel body, when the barrel cover is in a closed state, the real-time included angle between the barrel cover and the barrel body is zero, and when the barrel cover is completely opened, the real-time included angle between the barrel cover and the barrel body is a termination angle. When the real-time included angle is different, the opening degree of the barrel cover is different, for example, if the termination angle is 90 degrees, the real-time included angle is 30 degrees, the barrel cover is in an incompletely opened state, the opening between the barrel cover and the barrel body is smaller, and when the real-time included angle is 90 degrees, the barrel cover is in a completely opened state. Therefore, the opening degree of the current barrel cover can be judged according to the vertical of the real-time included angle.

In step S102, the corresponding relationship between the real-time included angle and the motor rotation speed is established, and the rotation speed of the motor is controlled according to the value of the real-time included angle, so that different real-time included angles can correspond to different motor rotation speeds, and the barrel cover has different turning speeds when the barrel cover is opened at different degrees. Therefore, the different rotating speeds of high-speed overturning and low-speed overturning can be simultaneously considered in the process of opening or closing the barrel cover, the time of the opening process or the closing process can be reduced by the high-speed overturning, and when the barrel cover is close to a limit position (such as a closing position or a complete opening position), the impact force between the barrel cover and the barrel body is reduced by utilizing the low rotating speed, so that the impact shaking and the noise are reduced.

In one exemplary embodiment, as shown in fig. 2, the control method includes the steps of:

step S201: acquiring an opening instruction of the barrel cover;

step S202: acquiring a real-time included angle between the barrel cover and the barrel body;

step S203: and controlling the motor to rotate in a first direction according to the opening instruction and the real-time included angle so as to open the barrel cover.

In this embodiment, step S202 is the same as step S101, and is not described herein again. In step S201 and step S203, the opening command is a command for controlling the opening of the tub cover. When the opening instruction is obtained, the motor is controlled to rotate in the first direction, so that the barrel cover is controlled to turn from a closed state to an open state, and the barrel cover is opened. In particular, the opening instruction may be an electrical signal triggered by the user, for example by providing an opening key which is generated when the user touches. Or an infrared sensor is arranged, an infrared signal of a user is received through an infrared sensing principle, when the user and the infrared sensor reach a preset distance, a starting instruction is triggered and generated, and starting signals of the user can be collected through sound control, photoelectric switches and other principles and are not listed one by one.

When the opening signal is obtained, it is necessary to ensure that the motor rotates in the first direction, and further the barrel cover is driven to turn over in the opening direction.

In an exemplary embodiment, obtaining the opening command also requires determining the current state of the lid, i.e., whether the lid is in the closed position. The method comprises the steps of obtaining a cover closing signal when the barrel cover is in a closed state, when the barrel cover is determined to be in the closed state, determining that the intention of a user is to open the barrel cover by combining a trigger signal of the user, generating an opening instruction by combining the closed state of the barrel cover and the trigger signal of the user, and controlling a motor to rotate in a first direction according to the opening instruction so as to open the barrel cover.

Understandably, when the barrel cover is in the fully opened state, if the trigger signal of the user is received, the intention of the user can be determined to be to close the barrel cover, and therefore, a closing instruction is generated by combining the fully opened state of the barrel cover and the trigger signal of the user.

It should be noted that, in this embodiment, an opening instruction or a closing instruction may be correspondingly generated only according to the state of the tub cover and the user trigger signal, so as to meet the user's intention, the control logic is simpler and more accurate, and the reliability of the product in the use process is improved.

In this embodiment, the signal when the real-time included angle is determined to be zero is a lid closing signal, so as to determine the closing state of the lid.

In an exemplary embodiment, as shown in fig. 3, controlling the motor to rotate in the first direction according to the turn-on command and the real-time angle comprises the steps of:

step S301: judging whether the real-time included angle is smaller than a first preset included angle, if so, executing a step S302, otherwise, executing a step S303;

step S302: controlling the motor to run at a first rotating speed;

step S303: judging whether the real-time included angle is larger than a second preset included angle, if so, executing a step S305, otherwise, executing a step S304;

step S304: controlling the motor to operate at a second rotating speed;

step S305: judging whether the real-time included angle is equal to the termination angle, if so, executing a step S307, otherwise, executing a step 306;

step 306: controlling the motor to operate at a third rotating speed;

step 307: and controlling the motor to stop rotating.

In this embodiment, the first predetermined included angle is smaller than the second predetermined included angle, the second predetermined included angle is smaller than the end angle, the first predetermined included angle is larger than zero, and the end angle ranges from 80 ° to 100 °. And the first rotational speed and the third rotational speed are both less than the second rotational speed.

Specifically, in step S301 and step S302, when the real-time included angle between the barrel cover and the barrel body is smaller than a first preset included angle, it is indicated that the barrel cover is in a starting stage of opening the barrel cover, in this process, the motor is controlled to rotate at a first rotation speed, so that the motor drives the barrel cover to turn over at a lower rotation speed, and a torque force between transmission structures in the starting stage of opening the barrel cover can be reduced.

It should be noted that the first preset included angle may be determined according to stress conditions between the drum covers and the transmission members of different devices, for example, an optimal angle is obtained through experimental data. For example, the first preset included angle may be 10 °, 15 °, 20 °, 25 °, or the like, and in the present embodiment, the first preset included angle is 20 °.

In the steps S303 and S304, when the real-time included angle is greater than the first preset included angle and less than the second preset included angle, the barrel cover is in an intermediate stage of the opening process, and in the process, the motor is controlled to rotate at the second rotation speed, so that the motor rotates at a higher speed, and the turnover speed of the barrel cover is increased, thereby achieving quick opening of the barrel cover, shortening the overall time of the opening process, increasing the opening efficiency, reducing the waiting time of a user, and improving the user experience.

In the steps S305 to S307, when the real-time included angle is larger than the second preset included angle and smaller than the end angle, the barrel lid is at the end stage of the opening process, in the process, the barrel lid gradually approaches the end position in the opening process, and in order to reduce the impact shaking caused by quick in-place opening, the motor is controlled to rotate at the third rotation speed, that is, the rotation speed of the motor is reduced to enable the barrel lid to operate in place at a low speed, and the barrel body is prevented from being greatly impacted and shaken at a full speed when the motor is in place.

In order to shorten the overall time for opening the cover, the second preset included angle is close to the end angle. In this embodiment, the termination angle is 90 °, and the second predetermined included angle ranges from 80 ° to 89 °.

It should be noted that, in step S305 and step S307, when the real-time included angle does not reach the end angle, it is indicated that the barrel cover is not completely opened, and at this time, the motor is still controlled to rotate in the first direction to drive the barrel cover to be opened, and the motor is controlled to stop rotating until the barrel cover is completely opened, so as to ensure that the barrel cover is opened in place, improve the reliability of opening the barrel cover, and solve the problem that the barrel cover automatically falls down after being opened to half and stopped in the existing device.

In an exemplary embodiment, the third speed is linearly changed from large to small, and when the real-time included angle between the barrel cover and the barrel body reaches the end angle, the third speed is reduced to zero, so as to further reduce the impact shaking.

In an exemplary embodiment, after the opening of the barrel cover is completed and the motor stops rotating, when a closing instruction is obtained, the motor is controlled to rotate in the second direction, so that the barrel cover is driven to reversely turn to complete the action of closing the cover. In this embodiment, the first direction is opposite to the second direction.

In this embodiment, the specific step of obtaining the close instruction includes:

step S401: acquiring a first moment when the motor stops rotating;

step S402: acquiring the current moment;

step S403: judging whether the time interval between the current moment and the first moment is greater than a preset time period, if so, executing a step S404, and if not, executing a step S402;

step S404: a close command is generated.

In this embodiment, when the barrel cover rotates to a fully open position, a real-time included angle between the barrel cover and the barrel body reaches a stop angle, and when the barrel body is fully opened, the barrel cover is ensured to be kept in an uncapped state for a preset time period, so as to achieve the purpose of time delay.

In other embodiments, the closing instruction may also be generated in response to a trigger signal of a user.

In an exemplary embodiment, as shown in fig. 4, after the closing command is obtained, the step of controlling the motor to rotate in the second direction according to the closing command and the real-time included angle includes the following steps:

step S501: judging whether the real-time included angle is larger than a third preset included angle, if so, executing a step S502, and if not, executing a step S503;

step S502: controlling the motor to operate at a fourth rotating speed;

step S503: and controlling the motor to run at a fifth rotating speed.

In this embodiment, the third predetermined included angle is greater than zero and smaller than the end angle, and the fifth rotation speed is smaller than the fourth rotation speed.

Specifically, in step S502 and step S503, the process of closing the lid is divided into a front stage and a rear stage by taking a third preset angle as a boundary, in the first stage, the real-time included angle is gradually reduced from the end angle to the third preset included angle, and in this stage, the motor is controlled to operate at a higher rotation speed, so as to realize rapid lid closing. When the real-time included angle is smaller than a third preset included angle, the motor is controlled to operate at a lower rotating speed, the overturning speed of the barrel cover is reduced, collision impact between the barrel cover and the barrel body is reduced until the barrel cover is completely closed, and then noise caused by closing the cover is reduced. In this embodiment, the third preset angle ranges from 25 ° to 35 °, for example, 25 °, 28 °, 30 °, 32 °, and the like.

In a specific embodiment, the fifth speed is linearly changed from large to small, and when the real-time included angle between the barrel cover and the barrel body is smaller than the third preset included angle, the overturning speed of the barrel body is linearly reduced to a slower speed to continue closing the cover, so as to further reduce the impact noise.

In an exemplary embodiment, in the uncovering stage, the first rotating speed, the second rotating speed and the third rotating speed are linearly changed, the first rotating speed is changed from small to large, the second rotating speed is increased first and then reduced, and the third rotating speed is changed from large to small, so that the overturning speed of the cover in the uncovering stage is integrally linearly changed, the uncovering process is smoother, and large impact shaking caused by the fact that the rotating speed of the motor is greatly instantly changed is avoided.

In the stage of closing the cover, the fourth rotating speed and the fifth rotating speed are linearly changed, and the fourth rotating speed and the fifth rotating speed are changed from large to small, so that the overturning speed of the cover in the stage of closing the cover is integrally linearly changed, the cover opening process is smoother, and the phenomenon that the instantaneous change of the rotating speed of the motor is large and the motor is suddenly stopped and generates large impact shaking is avoided.
