Description

Technical Field

[0001] The present application relates to the technical field of driving devices, and more particularly, to a driving control device, a toilet seat cover assembly, and a smart toilet. Background Art

[0002] Currently, driving devices are widely used in the technical field of sanitary equipment. For example, they are applied to smart toilets. The output shaft of the driving device is in transmission connection with a flipping assembly. The flipping assembly can be a toilet seat cover body, a seat ring, etc. The driving device can be used to control the flipping of the flipping assembly so that the flipping assembly is in a closed or opened state for the convenience of users.

[0003] Currently, due to the limitations of the structure of the driving device itself, during the process of controlling the flipping of the flipping assembly, the load of the electric driver of the driving device is large and small, and the entire electric driver runs unstably, which is not conducive to the electric driver to control the flipping movement of the flipping assembly. Summary of the Invention

[0004] Embodiments of the present application provide a driving control device, a toilet seat cover assembly, and a smart toilet to solve the above problems.

[0005] Embodiments of the present application achieve the above object through the following technical solutions.

[0006] In a first aspect, an embodiment of the present application provides a driving control device, including a housing, an output shaft, an electric driver, a transmission mechanism, and a slow-down elastic member. The output shaft is rotatably disposed in the housing. The electric driver is disposed in the housing and is in transmission cooperation with the output shaft. The slow-down elastic member is wound around the output shaft. One end of the slow-down elastic member is connected to the output shaft, and the other end is connected to the housing to be selectively tightened or released under the drive of the output shaft.

[0007] In a second aspect, an embodiment of the present application further provides a smart toilet assembly, which includes a mounting portion, a flipping assembly, and the above-mentioned driving control device. The flipping assembly is rotatably connected to the mounting portion. Among them, the housing is fixedly connected to the mounting portion, and the output shaft is in transmission connection with the flipping assembly, or the housing is fixed to the flipping assembly, and the output shaft is fixedly connected to the flipping assembly;

[0008] When the output shaft rotates relative to the housing, the driving control device is used to drive the flipping assembly to flip relative to the mounting portion to an opened state along a first circumferential direction or to a closed state along a second circumferential direction. The first circumferential direction and the second circumferential direction are opposite to each other. When the flipping assembly flips relative to the mounting portion along the second circumferential direction, the slow-down elastic member is used to generate a torque along the first circumferential direction.

[0009] In a third aspect, an embodiment of the present application further provides an intelligent toilet, which includes a toilet main body and the toilet seat cover assembly provided in the second aspect, and the toilet seat cover assembly is installed on the toilet main body.

[0010] Compared with the prior art, in the drive control device, the toilet seat cover assembly and the intelligent toilet provided by the present application, by winding the damping elastic member around the output shaft, one end of the damping elastic member is connected to the output shaft, and the other end is connected to the housing. The damping elastic member can generate a torque along the first circumferential direction. When applied to the toilet seat cover assembly and the intelligent toilet, it can reduce the influence of the gravity of the flipping assembly, thereby reducing the output power of the electric drive. At the same time, since the torque curve generated by the damping elastic member during the flipping process is approximately a cosine curve segment, therefore, the torque curve synthesized by the torque curve generated by the damping elastic member and the torque curve generated by the flipping assembly under the action of gravity is approximately a gentle straight line. The synthesized torque curve is the torque change corresponding to the electric drive at different flipping angles. Therefore, the torque of the electric drive changes gently with the flipping angle, making the operation of the electric drive stable and facilitating the control of the flipping movement of the flipping assembly by the electric drive.

Detailed implementation manners

[0027] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of this application.

[0028] Currently, during the flipping process of the flipping component, a certain amount of torque is applied to the flipping component jointly by a spiral spring and an electric driver, so as to drive the flipping component to flip to the open state. However, the inventor found that during the control process of the flipping action of the current electric driver, the main reason for the unstable operation of the electric driver is that: the torque applied by the spiral spring in the driving device to the flipping component varies greatly with the change of the flipping angle of the flipping component, which is caused by the unstable change of the torque of the spiral spring.

[0029] As Figure 1 shown is a schematic diagram of the force analysis of the flipping component under the torque generated by its own gravity and at different flipping angles. It can be seen from this that the torque T1 generated by the flipping component under its own gravity is T1 = L * A * cosα, where L is the distance from the center of mass of the flipping component to the rotation center of the flipping component, A is the weight of the flipping component itself, and α is the flipping angle; as Figure 2 shown is a change curve graph of the cosα value at different flipping angles. It can be seen from this that the cosα value gradually decreases from the flipping angle of 0° to 90°; as Figure 3 shown, curve a is the change curve of the torque T1 at different flipping angles. The torque T1 gradually decreases from the flipping angle of 0° to 90°. As Figure 4 in, curve b is the change curve of the torque T2 of the existing spiral spring at different flipping angles under the condition of no preloading (that is, when the spiral spring is subjected to an external pre-pressure), and curve c is the change curve of the torque T2 of the existing spiral spring at different flipping angles under the condition of no preloading. It can be seen from this that the change curves of the torque T2 of the spiral spring in the case of having preloading and no preloading are both oblique lines; as Figure 5The synthesized curve d shown is synthesized from curve a and curve b. The synthesized curve d is also the torque required for the electric drive to flip the flipping component to different flipping angles. It can be seen from this that the torque of the electric drive first increases sharply and then decreases sharply during the process where the flipping angle ranges from 0° to 30°, resulting in the load of the electric drive being large and small alternately, making the operation of the electric drive very unstable. The slope of the synthesized curve d during the flipping process from 30° to 90° is very large, indicating that the torque change of the electric drive is relatively sharp during this flipping process. This will also cause a large change in the load of the electric drive. Obviously, during the entire flipping process, it is not conducive to the electric drive to control the flipping movement of the flipping component.

[0030] In view of this, the inventor further devoted research, which at least included: the structure of the slow-down elastic member in the drive control device, the structural dimensions and shape of the slow-down elastic member, the number of coiled turns of the slow-down elastic member, and the change in the cross-sectional width of the slow-down elastic member, etc. After a large amount of research and analysis, the inventor proposed the drive control device, the toilet seat cover assembly, and the intelligent toilet provided in the embodiments of the present application.

[0031] An embodiment of the present application provides a drive control device, including a housing, an output shaft, an electric drive, and a slow-down elastic member. The output shaft is rotatably arranged in the housing. The electric drive is arranged in the housing and is in transmission cooperation with the output shaft. The slow-down elastic member is wound around the output shaft. One end of the slow-down elastic member is connected to the output shaft, and the other end is connected to the housing to be selectively tightened or released under the drive of the output shaft.

[0032] For the drive control device provided in the present application, when it is applied to the toilet seat cover assembly, since the slow-down elastic member is wound around the output shaft, one end of the slow-down elastic member is connected to the output shaft, and the other end is connected to the housing, the slow-down elastic member can generate a torque along the first circumferential direction to reduce the influence of the gravity of the flipping component, thereby reducing the output power of the electric drive. At the same time, since the torque curve generated by the slow-down elastic member during the flipping process of the toilet seat cover is approximately a cosine curve segment, therefore, the torque curve obtained by synthesizing the torque curve generated by the slow-down elastic member and the torque curve generated by the flipping component under the action of gravity is approximately a gentle straight diagonal line. The synthesized torque curve is the torque change corresponding to the electric drive at different flipping angles. Therefore, the torque of the electric drive changes gently with the flipping angle, making the operation of the electric drive stable and conducive to the electric drive to control the flipping movement of the flipping component.

[0033] Please refer to Figure 5 , this embodiment provides a drive control device 200, a toilet seat cover assembly 300, and an intelligent toilet 400. The intelligent toilet 400 includes the toilet seat cover assembly 300 and a toilet main body 410. The intelligent toilet 400 can have functions such as bidet washing, feminine washing, drying, and self-cleaning.

[0034] In this embodiment, the toilet bowl main body 410 is generally in a bucket-like structure, and the toilet bowl main body 410 is provided with a toilet bowl opening. The toilet seat cover assembly 300 is installed on the toilet bowl main body 410 and can selectively cover or open the toilet bowl opening.

[0035] Please refer to Figure 6 and Figure 7 , in this embodiment, the toilet seat cover assembly 300 includes a mounting portion 310, a flipping assembly 320, and a drive control device 200. The flipping assembly 320 is rotatably connected to the mounting portion 310 and can selectively flip to a closed state (as shown in Figure 5 ), or flip to an open state (as shown in Figure 6 ). The mounting portion 310 is detachably installed on the toilet bowl main body 410. In the closed state, the flipping assembly 320 covers the upper end surface of the toilet bowl main body 410 and covers the main toilet bowl opening. In the open state, the flipping assembly 320 flips relative to the toilet bowl main body 410 to an opening and closing angle, and the opening and closing angle can be greater than or equal to 80°, for example, the opening and closing angle can be greater than or equal to 90°. The flipping assembly 320 can include at least one of a seat ring and a toilet seat cover body. Hereinafter, an example in which the flipping assembly 320 includes a toilet seat cover body will be described:

[0036] In this embodiment, the mounting portion 310 is provided with a receiving space and a through hole communicating with the receiving space. The through hole is used to install the output shaft structure of the drive control device 200. The flipping assembly 320 is connected to the output shaft structure and can flip around the through hole. The receiving space can be used to install components such as the drive control device 200, the main control board, and the flushing assembly.

[0037] Please refer to Figure 8 and Figure 9 , in this embodiment, the drive control device 200 includes a housing 210, an output shaft 220, an electric driver 230, and a slow-down elastic member 250. The output shaft 220 is rotatably arranged in the housing 210. The electric driver 230 is arranged in the housing 210 and is in transmission cooperation with the output shaft 220. It should be noted that the electric driver 230 can be directly connected to the output shaft 220 in transmission, or in transmission cooperation through a transmission structure. The slow-down elastic member 250 is wound around the output shaft 220. One end of the slow-down elastic member 250 is connected to the output shaft 220, and the other end is connected to the housing 210 to be selectively tightened or released under the drive of the output shaft 220.

[0038] It should be noted that the housing 210 can be fixedly connected to the mounting portion 310, and the output shaft 220 is in transmission connection with the flipping assembly 320. Alternatively, the housing 210 is fixed to the flipping assembly 320, and the output shaft 220 is fixedly connected to the flipping assembly 320. When the output shaft 220 rotates under the driving force of the electric driver 230, the flipping assembly 320 can flip relative to the mounting portion 310 along with the output shaft 220.

[0039] Hereinafter, taking the housing 210 being fixedly connected to the mounting portion 310 and the output shaft 220 being in transmission connection with the flipping assembly 320 as an example, a specific description is given as follows:

[0040] Please refer to Figure 7 and Figure 10 , in this embodiment, the housing 210 of the drive control device 200 can be installed in the receiving space of the mounting portion 310. The housing 210 includes a front shell 211 and a rear shell 212. The front shell 211 and the rear shell 212 together enclose an installation space 213. The front shell 211 is provided with an assembly hole 2131 communicating with the installation space 213. The assembly hole 2131 is used for installing the output shaft 220. The assembly hole 2131 is opposite to the through hole of the mounting portion 310, so that the output shaft 220 of the drive control device 200 can extend out from the through hole.

[0041] Please refer to Figure 9 and Figure 10 , in this embodiment, the electric driver 230 is installed in the installation space 213 and can be fixed to the inner wall of the rear shell 212. The output shaft 220 is rotatably arranged in the housing 210. The output shaft 220 includes a transmission end 221 and a transmission end 222 connected to each other. The transmission end 222 is located in the installation space 213 and is in transmission cooperation with the electric driver 230 through a transmission mechanism 240. The transmission end 221 extends out of the installation space 213 through the assembly hole 2131 to be in transmission connection with the flipping assembly 320.

[0042] In some embodiments, such as Figure 9 and Figure 10As shown, the drive control device 200 may further include a transmission mechanism 240. The transmission mechanism 240 is in transmission cooperation with the rotating shaft of the electric driver 230 and the output shaft 220 to drive the output shaft 220 to rotate under the drive of the electric driver 230. The transmission mechanism 240 includes a worm and worm gear set 241, a reduction gear set 242 and an output gear 243 that are in transmission cooperation with the electric driver 230. The output gear 243 is fixed to the output shaft 220 and is spaced from the descent elastic member 250. The reduction gear set 242 is engaged between the output gear 243 and the worm and worm gear set 241. Since the transmission ratio of the worm and worm gear set 241 is large, the output shaft 220 can output a large torque to ensure the smooth flipping of the flipping assembly 320. Moreover, the structure of the worm and worm gear set 241 is compact, which can reduce the occupied space. Since the worm 2411 and worm gear 2412 set has self-locking property, it can lock the output shaft 220, thereby ensuring that the flipping assembly 320 maintains the opened state.

[0043] Exemplarily, the worm and worm gear set 241 includes a worm wheel 2411, a worm 2412 and a transmission gear 2413. The worm 2412 is fixedly connected to the rotating shaft of the electric driver 230 and is engaged with the worm wheel 2411. The transmission gear 2413 is coaxially and fixedly connected to the worm wheel 2411. Specifically, the reduction gear set 242 includes a first double gear 2421, a second double gear 2422 and an intermediate gear 2423. The second double gear 2422 is arranged side by side and spaced from the output gear 243. The second double gear 2422 is rotatably connected to the housing 210. Each of the first double gear 2421 and the second double gear 2422 includes a connected large gear and a small gear. The diameter of the addendum circle of the large gear is greater than that of the addendum circle of the small gear, and the module of the convex teeth of the large gear is greater than that of the convex teeth of the small gear. The first double gear 2421 is rotatably connected to the housing 210 and is located between the output gear 243 and the second double gear 2422. The small gear of the first double gear 2421 is engaged with the large gear of the second double gear 2422. The large gear of the first double gear 2421 is engaged with the transmission gear 2413. The intermediate gear 2423 is coaxially arranged with the first double gear 2421 and is engaged with the small gear of the second double gear 2422. Through the first double gear 2421 and the second double gear 2422, the stability of transmission can be ensured, and the torque of the output shaft 220 can be increased to ensure the reliability of the flipping assembly 320 during the opening and closing process. Through the reduction gear set 242, the rotation speed of the electric driver 230 can be reduced, and the output shaft 220 can drive the flipping assembly 320 to open and close smoothly at a relatively gentle speed. In addition, the electric driver 230 can also be in direct transmission cooperation with the output gear 243 through the first double gear 2421 or the second double gear 2422.

[0044] In some embodiments, the transmission mechanism 240 may be a transmission belt, a transmission sprocket, or the like. In addition, the electric driver 230 may also directly drive the output shaft 220 to rotate.

[0045] In this embodiment, the slow-down elastic member 250 is a scroll spring. The slow-down elastic member 250 is wound around the transmission end 222 of the output shaft 220. For example, the number of winding turns of the slow-down elastic member 250 around the outer circumference of the output shaft 220 may be two turns or more than two turns. For example, the number of winding turns may be an odd number of turns or an even number of turns. In addition, the number of winding turns of the slow-down elastic member 250 around the outer circumference of the output shaft 220 may also be a single turn or a non-integer number of turns (such as 1 / 2 turn, 3 / 2 turn, etc.). Specifically, the number of winding turns of the slow-down elastic member 250 can be set according to the torque that the slow-down elastic member 250 needs to bear, so that it can be applied to intelligent toilets 400 of different specifications and types.

[0046] In this embodiment, the slow-down elastic member 250 may be a flat scroll spring or other types of scroll structures. Under the action of torsion, the spring material of the flat slow-down elastic member 250 undergoes bending elastic deformation, causing the spring to twist in the plane, and the magnitude of the deformation angle is proportional to the torque. The flat slow-down elastic member may be a non-contact type flat scroll spring or a contact type flat scroll spring.

[0047] In this embodiment, the slow-down elastic member 250 includes a spring coil body 2511 wound around the output shaft 220 for at least one turn. Exemplarily, the slow-down elastic member 250 includes two adjacent spring coil bodies 2511. The projection of one of the adjacent spring coil bodies 2511 along the radial direction of the slow-down elastic member 250 may completely overlap the projection of the other. In this way, the two adjacent spring coil bodies 2511 can be stacked as much as possible in the axial direction of the slow-down elastic member 250, reducing the width dimension of the slow-down elastic member 250 along its axial direction. In this embodiment, the spring coil body 2511 is a sheet structure with a relatively thin thickness. Exemplarily, the maximum cross-sectional width dimension of the spring coil body 2511 may be greater than or equal to 3 times or more than 3 times the thickness of the spring coil body 2511, and can be specifically adjusted according to actual needs.

[0048] In this embodiment, one end of the slow-down elastic member 250 is fixedly connected to the transmission end 222, and the other end can be fixedly connected to the rear shell 212. When the output shaft 220 rotates relative to the outer shell 210, the drive control device 200 can drive the flipping assembly 320 to flip relative to the mounting portion 310 along the first circumferential direction X1 to the open state, or flip along the second circumferential direction X2 to the closed state, and the first circumferential direction X1 and the second circumferential direction X2 are reverse to each other. When the flipping assembly 320 flips relative to the mounting portion 310 along the second circumferential direction X2, the slow-down elastic member 250 is tightened, and the coils of the slow-down elastic member 250 can be in close contact with each other and are all tightly wound around the outer circumference of the output shaft 220. Therefore, the slow-down elastic member 250 can generate a torque along the first circumferential direction X1. The torque generated by the slow-down elastic member 250 along the first circumferential direction X1 can partially offset the gravitational force of the flipping assembly 320. In this way, the electric driver 230 only needs to output a smaller torque to drive the flipping assembly 320 to overcome the torque of its own gravitational force and flip along the first circumferential direction X1 to the open state, thereby reducing the output power of the electric driver 230.

[0049] In this embodiment, when the flipping assembly 320 is in the closed state, the torque generated by the slow-down elastic member 250 along the first circumferential direction X1 is less than the weight of the flipping assembly 320. For example, when the torque generated by the slow-down elastic member 250 along the first circumferential direction X1 is less than the torque generated by the self-gravitational force of the toilet seat cover body, the toilet seat cover body can remain in the closed state under the action of its own weight. When the electric driver 230 generates a torque along the first circumferential direction X1 on the toilet seat cover body, the torque generated by the electric driver 230 and the torque generated by the slow-down elastic member 250 along the first circumferential direction X1 act together to overcome the torque generated by the self-gravitational force of the toilet seat cover body, so as to drive the toilet seat cover body to flip to the open state.

[0050] Please refer to Figure 13 and Figure 14 In this embodiment, the slow-down elastic member 250 can be connected to the transmission end 221 and the rear shell 212 by a snap connection. Specifically, the slow-down elastic member 250 includes an elastic coil body 251, a first snap connection end 253, and a second snap connection end 254. The elastic coil body 251 is wound around the outer circumference of the output shaft 220. The elastic coil body 251 includes multiple coil spring bodies 2511, and the multiple coil spring bodies 2511 are connected in sequence and wound around the outer circumference of the output shaft 220. In this embodiment, the first snap connection end 253 and the second snap connection end 254 are respectively connected to two connection ends of the elastic coil body 251. The two connection ends are respectively the innermost end and the outermost end of the elastic coil body 251. The first snap connection end 253 can be bent relative to the innermost end, and it can be bent to be substantially parallel to the radial direction of the elastic coil body 251. The output shaft 220 is provided with a slot portion 223, and the first snap connection end 253 is embedded in the slot portion 223 to be snap-connected to the output shaft 220.

[0051] In this embodiment, the second clamping end 254 is connected to the outermost end of the elastic ring body 251 and is clamped with the housing 210. Specifically, the rear housing 212 is provided with a slot structure 2121, the opening of the slot structure 2121 is arranged facing the output shaft 221, the second clamping end 254 is bent relative to the outermost end of the elastic ring body 251, and it can be bent to be substantially parallel to the radial direction of the elastic ring body 251. The second clamping end 254 can be inserted into the slot structure 2121 from the opening.

[0052] In addition, the slow-down elastic member 250 can also be connected to the transmission end 221 and the rear housing 212 by means of fastener connection, welding, etc.

[0053] Please continue to refer to Figure 13 and Figure 14 , in this embodiment, the slot portion 223 includes a first stop wall 2231 and a second stop wall 2232. The first stop wall 2231 and the second stop wall 2232 are arranged at an angle along the circumferential direction of the output shaft 220. The angle β between the first stop wall 2231 and the second stop wall 2232 can be greater than or equal to 90°, or the first stop wall 2231 and the second stop wall 2232 can also be arranged in parallel at intervals, and the angle β between the two is 0°. Specifically, it can be adjusted according to actual needs to meet the different idle rotation strokes of the flipping assembly 320. The first clamping end 253 is connected to abut against the first stop wall 2231 or the second stop wall 2232.

[0054] When the output shaft 220 of the electric driver 230 rotates along the first circumferential direction X1, it can drive the flipping assembly 320 to flip relative to the mounting portion 310 along the second circumferential direction X2 to the closed state. During this process, the first clamping end 253 abuts against the first stop wall 2231, and under the action of the first stop wall 2231, the first clamping end 253 drives the elastic ring body 251 to continuously tighten, and the slow-down elastic member 250 generates a torque along the first circumferential direction X1 on the flipping assembly 320. When the output shaft 220 of the electric driver 230 rotates along the second circumferential direction X2, it can drive the flipping assembly 320 to flip relative to the mounting portion 310 along the first circumferential direction X1 to the open state. During this process, the first clamping end 253 of the slow-down elastic member 250 will abut against the first stop wall 2231 and act on the flipping assembly 320 with a torque along the first circumferential direction X1 through the output shaft 220. In this way, the electric driver 230 only needs to act on the flipping assembly 320 with a smaller torque along the first circumferential direction X1 to overcome the torque generated by the weight of the flipping assembly 320 so that the flipping assembly 320 can flip. Since the first stop wall 2231 and the second stop wall 2232 are arranged at an angle along the circumferential direction of the output shaft 220, the slow-down elastic member 250 can continue to move by means of this angle to apply a torque to the flipping assembly 320, and the flipping assembly 320 can idle to a larger opening and closing angle.

[0055] In some embodiments, as Figure 13 shown, the descent elastic member 250 has a cross-sectional width dimension W along the axial direction of the descent elastic member 250. The cross-sectional width dimension W can be equal everywhere along the curling direction of the descent elastic member 250, and the descent elastic member 250 has a constant cross-sectional structure. Herein, the curling direction refers to the direction in which the descent elastic member 250 is curled from the outermost end to the innermost end. By setting the descent elastic member 250 as a cross-sectional structure, it can be ensured that each part of the descent elastic member 250 has a high strength, improving its service life, and ensuring that its torque changes smoothly with the change of the flipping angle, which is beneficial for the electric driver 230 to control the flipping motion.

[0056] In some embodiments, as Figure 13 shown, the descent elastic member 250 has opposite first side surface 252 and second side surface 255 along its axial direction. The first side surface 252 and the second side surface 255 are arranged around the output shaft 220. The distance between the first side surface 252 and the second side surface 255 is defined as the cross-sectional width dimension. Herein, the first side surface 252 and the second side surface 255 are arranged in multiple turns around the output shaft 220. Exemplarily, the first side surface 252 and the second side surface 255 can be substantially planar. The adjacent two turns of the first side surface 252 are substantially flush, and the adjacent two turns of the second side surface 255 are substantially flush. Both can be substantially parallel to the radial direction of the output shaft 220. This is not only convenient for processing, but also can ensure that the descent elastic member 250 has a small size along its axial direction, avoiding occupying too much axial length of the output shaft 220.

[0057] It should be noted that the maximum torque T of the descent elastic member 250 is positively correlated with the cross-sectional width dimension W of the descent elastic member 250 and the thickness of the descent elastic member 250. The initial torque T of the descent elastic member 250 is positively correlated with the cross-sectional width dimension W1 of the outermost end of the descent elastic member 250.

[0058] As Figure 15 shown, when the flipping assembly 320 is flipped relative to the mounting portion 310 to a flipping angle α, the torque generated by the descent elastic member 250 along the first circumferential direction X1 is equal to the torque Tα generated by the weight of the flipping assembly 320 at the flipping angle α, where Tα = L * A * cosα, where L is the distance from the centroid of the flipping assembly 320 to the rotation center of the flipping assembly 320, A is the weight of the flipping assembly 320, and the flipping angle α is less than 90°, for example, the flipping angle α is greater than or equal to 70° and less than or equal to 80°.

[0059] As Figure 15As shown, curve e is the torque curve generated by the slow-down elastic member during the flipping process of the flip cover. Its torque curve is approximately a cosine curve segment. The composite curve f is the torque curve obtained by combining the torque curve generated by the slow-down elastic member and the torque curve generated by the flipping assembly under its own gravity. From Figure 15 it can be seen that the composite curve f is approximately a gentle straight line with a low slope. The composite torque curve is the torque change corresponding to the electric driver 230 at different flipping angles. Therefore, the torque of the electric driver 230 changes gently with the change of the flipping angle, making the electric driver 230 operate smoothly and facilitating the control of the flipping movement of the flipping assembly 320 by the electric driver 230.

[0060] In some embodiments, when the flipping assembly 320 is flipped relative to the mounting portion 310 to the opened state, the slow-down elastic member 250 can generate a torque along the second circumferential direction X2. In this way, when the electric driver 230 stops working, the flipping assembly 320 can be maintained in the opened state under the action of the slow-down elastic member 250, preventing the flipping assembly 320 from continuing to flip to a larger opening and closing angle. As Figure 15 shown, when the flipping assembly is flipped to 90°, the slow-down elastic member 250 can generate a torque of -0.2 N·m along the second circumferential direction X2. When the electric driver 230 stops working, the torque generated by the slow-down elastic member 250 can maintain the opened state of the flipping assembly 320.

[0061] The drive control device 200, the toilet seat cover assembly 300, and the intelligent toilet provided by the present application are configured by winding the slow-down elastic member 250 around the output shaft 220. One end of the slow-down elastic member 250 is connected to the output shaft 220, and the other end is connected to the housing 210. The slow-down elastic member 250 can generate a torque along the first circumferential direction X1 to reduce the influence of the gravity of the flipping assembly 320, thereby reducing the output power of the electric driver 230. At the same time, since the torque curve generated by the slow-down elastic member 250 during the flipping process is approximately a cosine curve segment, the torque curve obtained by combining the torque curve generated by the slow-down elastic member 250 and the torque curve generated by the flipping assembly 320 under the action of gravity is approximately a gentle straight line. The composite torque curve is the torque change corresponding to the electric driver 230 at different flipping angles. Therefore, the torque of the electric driver 230 changes gently with the flipping angle, making the electric driver 230 operate smoothly and facilitating the control of the flipping movement of the flipping assembly 320 by the electric driver 230.
