When the angle is greater than the first preset angle, the toilet seat is controlled to flip to the seat limit position at a preset vibration frequency to compensate for the increased rebound amplitude caused by the structural gap between the seat gears after the toilet seat hits the seat limit position and rebounds, wherein the structural gap includes the meshing gap between the seat drive gears; and / or, the toilet seat is controlled to approach the seat limit position at a preset vibration frequency after each collision with the seat limit position, so as to disrupt the vibration frequency of the toilet seat caused by repeated rebounds.

[0009] Preferably, the method further includes: when the rotational angular velocity of the toilet seat is less than a preset angular velocity for a preset time, eliminating the vibration frequency of the toilet seat.

[0010] Preferably, the method further includes: after confirming that the toilet seat is in the seat limit position, driving the toilet seat motor to rotate forward for a third preset time to ensure that the toilet seat is stably in the seat limit position. Confirming the opening angle of the toilet seat includes: obtaining the opening angle of the toilet seat through an angle sensor.

[0011] Preferably, the method further includes: when the angle between the toilet seat cover and the toilet bowl is greater than a second preset angle and less than a first preset angle, reducing the output torque of the toilet seat cover motor so that the toilet seat cover decelerates to reach the first preset angle.

[0013] Preferably, the device further includes a thrust application unit, which, after confirming that the toilet seat has reached the seat limit position, drives the toilet seat motor to rotate forward for a third preset time to ensure that the toilet seat is in the seat limit position.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The concept of this application is to address the issue that in the existing technology, toilet seat covers vibrate after hitting the limit position during opening. The application proposes an automatic toilet seat opening method. This method, after the toilet seat cover is opened to a certain angle, uses a preset frequency of pushing and pulling force to drive the toilet seat cover to the limit position, thereby breaking the frequency-based vibration between the cover and the limit position. Simultaneously, this application can compensate for the increased vibration amplitude caused by the gear structure clearance of the toilet seat cover.

[0026] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] This application provides an automatic opening method, device, toilet, and system for a toilet seat cover. The toilet seat cover consists of a housing and an automatic flip-top mechanism. The automatic flip-top mechanism is provided on one side of the housing and a connecting shaft is provided on the other side. The automatic flip-top mechanism includes a gear set and a cover motor, an electromagnetic clutch, a torque balancing component, etc., which are sequentially connected through the gear set.

[0028] like Figure 1 The diagram shows a flowchart of an automatic toilet seat cover opening method according to an embodiment of this application. The method includes at least the following steps S110 to S120:

[0029] Step S110: Confirm the opening angle of the toilet seat cover, wherein the opening angle includes the angle between the toilet seat cover and the toilet bowl, and the cover includes the toilet lid and the toilet seat ring.

[0030] In this application, the opening angle of the toilet seat is obtained through an angle sensor. The boundary range of the opening angle includes the angle formed by the seat and the toilet bowl surface, and the opening angle when the seat reaches the limit position, where the limit position restricts the opening angle of the seat. The toilet seat in this application includes not only the toilet lid but also the toilet seat ring; therefore, it is understood that this application can control the opening and closing of the toilet lid independently, or simultaneously control the opening and closing of both the toilet lid and the toilet seat ring.

[0031] It is understood that due to sensor measurement errors and structural errors in the cover gear, the obtained cover opening angle may have some error. Therefore, the cover opening angle in this application can be represented by the cover travel. Specifically, the toilet cover travel is calculated from the position angle of the toilet cover. For example, when the toilet cover is in the bowl position, the angle sensor obtains the toilet cover angle, for example, -5 degrees. When the toilet cover is in the flip-up position, the angle sensor obtains the toilet cover angle, for example, 100 degrees. Therefore, the toilet cover travel is 110 degrees. In reality, the measurement of the cover travel is related to the accuracy of the angle sensor and is usually represented using an AD value. The AD value is the value after converting an analog quantity into a digital quantity; A refers to the analog quantity, and D refers to the digital quantity. The AD value is the final presentation form of the data.

[0032] Step S120: Based on the angle between the toilet seat cover and the toilet bowl, a rotation frequency is generated to control the rotation of the cover motor, causing the toilet seat cover to open to the limit position according to a preset vibration frequency.

[0033] In this application, the rotation frequency of the motor includes driving the toilet seat motor to rotate forward for a first preset time, then reverse for a second preset time, and repeating this process to obtain a preset vibration frequency of the toilet seat, wherein the first preset time is greater than the second preset time; the step of generating a rotation frequency of the seat motor based on the angle between the toilet seat and the toilet bowl surface, so that the toilet seat opens to the seat limit position according to the preset vibration frequency, includes: when the angle... When the angle is greater than the first preset angle, the toilet seat is controlled to flip to the seat limit position at a preset vibration frequency to compensate for the increased rebound amplitude caused by the structural gap between the seat gears after the toilet seat hits the seat limit position and rebounds, wherein the structural gap includes the meshing gap between the seat drive gears; and / or, the toilet seat is controlled to approach the seat limit position at a preset vibration frequency after each collision with the seat limit position, so as to disrupt the vibration frequency of the toilet seat caused by repeated rebounds.

[0034] In this application, the rotation of the cover plate requires the output torque of the cover plate motor, which drives the cover plate to rotate through the interaction of the cover plate gears. Since there is a structural gap between the gears, the existence of the push-pull force in this application can compensate for part of the structural gap, thus reducing the vibration amplitude of the cover plate. Specifically, when the cover plate rebounds upon impact, the existence of the gear structural gap causes the vibration amplitude of the cover plate to increase by at least one gear structural gap. If the rotation direction of the motor cover plate gears is exactly opposite to the rotation direction of the cover plate at this time, then the gear structural gap can be compensated for.

[0035] In this application, because the smart toilet seat needs to overcome gravity and structural resistance during the opening (flipping) process, the flipping motor requires a large torque to flip the seat. Once the seat is fully open, it collides with the seat limiter, at which point the seat rebounds. The angle of rebound is related to the impact force. The seat limiter is generally located at the bottom of the seat. In this situation, the interaction between the seat and the seat limiter causes the seat to vibrate significantly. Furthermore, because the toilet seat continuously receives pressure from the lid and the rebound force from the seat limiter after flipping, these two opposing forces also cause the seat to vibrate at a certain frequency, with the vibration amplitude gradually decreasing and eventually disappearing.

[0036] In this application, the following technical measures were taken to reduce and eliminate the vibration of the toilet seat:

[0037] The toilet seat travel is monitored. When the angle sensor detects that the toilet seat has reached a preset position (e.g., 90% of the total travel) but has not reached the vertical position, the toilet seat is decelerated. Specifically, this can be achieved by reducing the motor's output torque. Alternatively, a reverse pulling force can be applied (controlling the motor to reverse and output reverse torque) to further decelerate the seat's rotation. The seat's inertia combined with the motor's torque will allow it to continue into position without accelerating. This deceleration during rotation reduces the impact force between the seat and the seat's limit position.

[0038] While slowing down the toilet seat before it reaches the vertical position can reduce the force of the impact between the seat and the limit switch, due to control precision limitations, it's impossible to guarantee that the speed will drop to zero when the seat reaches the vertical position. Furthermore, due to gravity, the seat will accelerate after flipping more than 90 degrees, increasing the impact force between the seat and the limit switch. Additionally, to ensure the toilet seat closes properly, a continuous thrust is applied for a period of time to ensure the seat reaches the limit switch position. All of these factors contribute to the impact between the seat and the limit switch, causing the seat to vibrate.

[0039] In this application, when the lid is detected to be perpendicular to the toilet bowl surface (first preset angle), a push-pull (pull-pull) positive force is applied to the lid. Specifically, the lid motor is controlled to move forward for a period of time and then reverse for a period of time, with the forward time > the reverse time. At this time, the lid generally flips backward, but there is a pulsating pulling force. This pulsating pulling force is related to the structural gap between the motor and the lid, as well as the length and weight of the lid. It is a coefficient that can be adjusted to achieve deceleration before the lid reaches its final position and vibration frequency after it reaches its final position, thereby making the lid flip smoothly, reducing the vibration amplitude and vibration time, and improving the user's perception. Specifically, since the vibration frequency between the lid and the lid limit is low, a higher frequency is set when setting the push-pull force frequency to ensure that the two frequencies do not resonate.

[0040] In some embodiments of this application, when the angle between the toilet seat and the toilet bowl is greater than a second preset angle but less than a first preset angle, the output torque of the toilet seat motor is reduced to decelerate the toilet seat to the first preset angle. When the rotational angular velocity of the toilet seat is less than a preset angular velocity for a preset time, the vibration frequency of the toilet seat is cleared. After confirming that the toilet seat is in the seat limit position, the toilet seat motor is driven to rotate forward for a third preset time to ensure that the toilet seat is stably in the seat limit position.

[0041] like Figure 2 As shown in this application, when someone is detected approaching, the toilet automatically initiates the process of opening the lid. As the opening angle of the lid increases, the output torque of the lid motor also changes accordingly to prevent excessive opening force, which could lead to excessive impact force when the lid hits the lid limit. When the toilet lid's travel exceeds a preset value, such as 90% (the travel and angle of rotation can be converted to each other; the position where the travel is 90% is the second preset angle in this application), the lid has not yet reached the vertical position (the first preset angle). At this time, deceleration can effectively reduce the rotation speed of the lid. After passing the vertical position, the presence of gravity on the lid will cause it to accelerate its rotation. Due to the precision of motor control, it is difficult to achieve a situation where the speed of the lid opening to contact the lid limit is exactly zero; normally, it will rebound after reaching the lid limit. In addition, if the lid does not contact the lid limit, the subsequent thrust applied to ensure the lid is in place will also cause the lid to collide with the lid limit, resulting in a rebound. In this application, a push-pull force with a relatively high preset frequency can disrupt the resonance between the rebound force and the push force, thereby reducing the amplitude and duration of the vibration.

[0042] Specifically, when the cover plate reaches a 90° position on the pot surface, the motor torque and speed are controlled to apply a pushing force (e.g., 10ms) to the cover plate, followed by a pulling force (e.g., 5ms). This alternating action results in the cover plate receiving a combined pushing and pulling force at a fixed frequency, slowly approaching the cover plate limit. The cover plate has a built-in preset fixed frequency (its inherent vibration frequency), which is virtually imperceptible to the naked eye. This inherent vibration frequency is the frequency of vibration after the cover plate collides with the cover plate limit. In practical implementation, due to the influence of gravity after the cover plate reaches a 90° position on the pot surface, this application needs to comprehensively consider the mass of the cover plate and the influence of gravity to obtain a suitable coefficient to reduce or even eliminate the vibration of the cover plate.

[0043] The method for confirming the cover plate's position in this application is not by using a position sensor, but by confirming the position based on the cover plate's rotational angular velocity. Specifically, an angle sensor is used, and the angle sensor uses AD values ​​to represent the angle. For example, if the cover plate's movement angle is less than 3AD within 100ms, then the cover plate stops moving. If this state lasts for 1 second, then the cover plate is confirmed to be in position.

[0044] In this application, for fault tolerance, once the cover plate is confirmed to be in place, a pre-set pushing force is applied to ensure proper cover plate rotation in case of abnormalities during the cover plate opening process, such as sensor malfunctions or motor malfunctions. Specifically, a pressing force is applied for 2 seconds to ensure normal cover plate rotation.

[0045] This application embodiment also provides an automatic opening device 300 for a toilet seat cover, such as... Figure 3 The diagram shows an automatic opening structure for a toilet seat cover according to an embodiment of this application. The device 300 includes at least: an angle confirmation unit 310 and a vibration frequency application unit 320, wherein:

[0046] In one embodiment of this application, the angle confirmation unit 310 is specifically used to: confirm the opening angle of the toilet seat cover, wherein the opening angle includes the angle between the toilet seat cover and the toilet bowl, and the cover includes a toilet lid and a toilet seat ring.

[0047] In this application, the opening angle of the toilet seat is obtained by an angle sensor. The boundary range of the opening angle includes the angle formed by the seat and the toilet bowl surface and the opening angle when the seat reaches the seat limit position, wherein the seat limit is used to restrict the opening angle of the seat.

[0048] It is understood that due to sensor measurement errors and structural errors in the cover gear, the obtained cover opening angle may have certain errors. Therefore, the cover opening angle in this application can be represented by the cover travel. Specifically, the toilet cover travel is calculated from the position angle of the toilet cover. For example, when the toilet cover is in the bowl position, the angle sensor obtains the toilet cover angle, for example, -5 degrees. When the toilet cover is in the flip-up position, the angle sensor obtains the toilet cover angle, for example, 100 degrees. Based on this, the travel of the toilet cover is 110 degrees. In reality, the measurement of the cover travel is related to the accuracy of the angle sensor and is usually represented by the AD value.

[0049] In one embodiment of this application, the vibration frequency application unit 320 is specifically used to: generate a rotation frequency for controlling the rotation of the cover motor according to the angle between the toilet seat cover and the toilet bowl, so that the toilet seat cover opens to the cover limit position of the toilet seat cover according to the preset vibration frequency.

[0050] In this application, the rotation frequency of the motor includes driving the toilet seat motor to rotate forward for a first preset time, then reverse for a second preset time, and repeating this process to obtain a preset vibration frequency of the toilet seat, wherein the first preset time is greater than the second preset time; the step of generating a rotation frequency of the seat motor based on the angle between the toilet seat and the toilet bowl surface, so that the toilet seat opens to the seat limit position according to the preset vibration frequency, includes: when the angle... When the angle is greater than the first preset angle, the toilet seat is controlled to flip to the seat limit position at a preset vibration frequency to compensate for the increased rebound amplitude caused by the structural gap between the seat gears after the toilet seat hits the seat limit position and rebounds, wherein the structural gap includes the meshing gap between the seat drive gears; and / or, the toilet seat is controlled to approach the seat limit position at a preset vibration frequency after each collision with the seat limit position, so as to disrupt the vibration frequency of the toilet seat caused by repeated rebounds.

The method as described in claim 1, characterized in that, The method further includes: When the angle between the toilet seat cover and the toilet bowl is greater than the second preset angle but less than the first preset angle, the output torque of the toilet seat cover motor is reduced so that the toilet seat cover decelerates to reach the first preset angle.

6. An automatic opening device for a toilet seat cover, characterized in that, The device includes: An angle confirmation unit confirms the opening angle of the toilet seat cover, wherein the opening angle includes the angle between the toilet seat cover and the toilet bowl, and the cover includes a toilet lid and a toilet seat ring. The vibration frequency application unit generates a rotation frequency for controlling the rotation of the cover motor based on the angle between the toilet seat cover and the toilet bowl surface, so that the toilet seat cover opens to the cover limit position of the toilet seat cover according to the preset vibration frequency. The rotation frequency of the motor includes driving the toilet seat motor to rotate forward for a first preset time, then to rotate in reverse for a second preset time, and repeating this process to obtain a preset vibration frequency of the toilet seat, wherein the first preset time is greater than the second preset time. The step of generating a rotation frequency for controlling the lid motor based on the angle between the toilet seat cover and the toilet bowl surface, so that the toilet seat cover opens to the limit position of the toilet seat cover according to a preset vibration frequency, includes: When the included angle is greater than the first preset angle, the toilet seat is controlled to flip to the seat limit position at a preset vibration frequency to compensate for the increased rebound amplitude caused by the structural gap between the seat gears after the toilet seat hits the seat limit position and rebounds. The structural gap includes the meshing gap between the seat drive gears. The toilet seat is controlled to vibrate at a preset frequency, so that after each impact and rebound, the position of the toilet seat is close to the limit position of the seat, thereby disrupting the vibration frequency of the toilet seat caused by repeated rebounds.

7. The apparatus as described in claim 6, characterized in that, The device also includes, The thrust application unit, after confirming that the toilet seat has reached the seat limit position, drives the toilet seat motor to rotate forward for a third preset time to ensure that the toilet seat is in the seat limit position.

8. A toilet seat, comprising: Automatic opening device and processor for toilet seat cover; And a memory arranged to store computer-executable instructions, which, when executed, cause the processor to perform the method of any one of claims 1 to 5.

9. A computer-readable storage medium storing one or more programs, which, when executed by a toilet comprising a plurality of applications, cause the toilet to perform any of the methods described in claims 1 to 5.
