Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to a motor drive hinge shaft fine-tuning structure, a smart toilet seat, and a smart toilet. Background Technology

[0002] Most existing smart toilet seat flip-top solutions rely on the motor's rotation axis coinciding with the hinge's rotation axis for transmission via a coaxial connection. This presents the following problems: 1. The coincidence of the motor's and hinge's rotation axes results in relatively fixed installation positions. Different motor covers need to be custom-made to accommodate different installation locations, leading to high mold development costs. 2. The fit between the flip-top and the back cover of the mechanism needs to be within acceptable limits. With a fixed hinge rotation axis, the flip-top manufacturing technology is highly demanding, resulting in a high number of scrapped flip-tops during production due to non-compliant injection molding dimensions. Utility Model Content

[0003] This utility model aims to at least partially solve one of the aforementioned technical problems in related technologies. To this end, this utility model proposes a motor drive hinge shaft fine-tuning structure.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model also proposes an intelligent cover plate with the above-mentioned motor drive hinge axis fine-tuning structure.

[0006] This utility model also proposes an intelligent toilet with the above-mentioned motor drive hinge axis fine-tuning structure.

[0007] According to the first aspect of the present invention, the motor drive hinge shaft fine-tuning structure includes:

[0008] The motor assembly includes a relatively fixed motor and a first adjusting ring, wherein the inner or outer ring of the first adjusting ring is provided with a first meshing tooth;

[0009] The connecting arm has a second adjusting ring, the inner or outer ring of which is provided with a second meshing tooth;

[0010] An angle adjustment wheel is circular in shape, with a third meshing tooth on the inner ring and a fourth meshing tooth on the outer ring. The number of teeth on the third meshing tooth is not equal to the number of teeth on the fourth meshing tooth.

[0011] When the first meshing tooth is located on the inner ring of the first adjusting ring, the second meshing tooth is located on the outer ring of the second adjusting ring, and the third meshing tooth meshes with the second meshing tooth, and the fourth meshing tooth meshes with the first meshing tooth; when the first meshing tooth is located on the outer ring of the first adjusting ring, the second meshing tooth is located on the inner ring of the second adjusting ring, and the fourth meshing tooth meshes with the second meshing tooth, and the third meshing tooth meshes with the first meshing tooth.

Detailed Implementation

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] Reference Figure 1-7 A motor drive hinge shaft fine-tuning structure, comprising:

[0038] The motor assembly includes a relatively fixed motor 200 and a first adjusting ring 110, the inner or outer ring of the first adjusting ring 110 being provided with first meshing teeth 111; the motor 200 is used to generate the torque required for the flip cover 700 to flip.

[0039] The connecting arm 300 has a second adjusting ring 310, and the inner or outer ring of the second adjusting ring 310 is provided with a second meshing tooth 311;

[0040] Angle adjustment wheel 400 is in the shape of a ring. Its inner ring is provided with a third meshing tooth 410 and its outer ring is provided with a fourth meshing tooth 420. The number of teeth of the third meshing tooth 410 and the number of teeth of the fourth meshing tooth 420 are not equal.

[0041] When the first meshing tooth 111 is located on the inner ring of the first adjusting ring 110, the second meshing tooth 311 is located on the outer ring of the second adjusting ring 310, and the third meshing tooth 410 meshes with the second meshing tooth 311, and the fourth meshing tooth 420 meshes with the first meshing tooth 111; when the first meshing tooth 111 is located on the outer ring of the first adjusting ring 110, the second meshing tooth 311 is located on the inner ring of the second adjusting ring 310, and the fourth meshing tooth 420 meshes with the second meshing tooth 311, and the third meshing tooth 410 meshes with the first meshing tooth 111.

[0042] The drive gear 500 is connected to the output shaft of the motor 200. The rotation axis of the drive gear 500 is coaxial with the axis of the angle adjustment wheel 400, ensuring that the deflection of the connecting arm 300 does not affect the meshing of the driven gear part 620 and the drive gear 500. The drive gear 500 receives the torque generated by the motor 200 through the shaft connection and transmits the torque to the driven swing arm 600 through the transmission teeth on its surface.

[0043] The driven swing arm 600 has a swing arm portion 610 and a driven gear portion 620. The driven gear portion 620 is rotatably connected to the connecting arm 300. The driven gear portion 620 meshes with the driving gear 500. The driven swing arm 600 receives the torque of the driving gear 500 through the transmission teeth on the surface of the driven gear portion 620, causing the flip cover 700 to flip up.

[0044] Working principle (example): The inner ring of the angle adjusting wheel 400 has 60 meshing teeth, each corresponding to an angle of 6 degrees. The outer ring has 72 meshing teeth, each corresponding to an angle of 5 degrees. The difference in the number of teeth between the inner and outer rings causes the connected parts (first adjusting ring 110 and connecting arm 300) to rotate in both directions, resulting in a slight 1-degree deflection of the connecting arm 300 relative to the motor assembly, thereby adjusting the rotation axis of the driven swing arm 600. For example... Figure 5-6As shown, after the connecting arm 300 deflects downward, the rotation axis of the driven swing arm 600 moves downward, causing the flip cover 700 connected to the driven swing arm 600 to also move downward. A motor-driven hinge axis fine-tuning structure is installed on both the left and right sides of the flip cover 700, allowing the flip cover 700 to be adjusted as follows: 1. Left side deflects upward, right side remains stationary, suitable for cases where the left side of the flip cover 700 has a low step height; 2. Left side deflects downward, right side remains stationary, suitable for cases where the left side of the flip cover 700 has a high step height; 3. Left side remains stationary, right side deflects upward, suitable for cases where the right side of the flip cover 700 has a low step height; 4. Left side remains stationary, right side deflects downward, suitable for cases where the right side of the flip cover 700 has a high step height; 5. Left side deflects upward, right side deflects upward, suitable for cases where the overall step height of the flip cover 700 is low; 6. Left side deflects downward, right side deflects downward, suitable for cases where the overall step height of the flip cover 700 is high.

[0045] In some embodiments of this utility model, the motor assembly includes a motor cover 100, which has a first adjusting ring 110 and a receiving cavity 130. The motor 200 is embedded in the receiving cavity 130, the first adjusting ring 110 is located on one side of the receiving cavity 130, and the output shaft of the motor 200 passes through the first adjusting ring 110. The motor cover 100 is generally horizontally fixed to the motor 200.

[0046] In some embodiments of this utility model, the end face of the first adjusting ring 110 facing the second adjusting ring 310 is provided with a plurality of first scales 112, which are arranged circumferentially along the first adjusting ring 110, and each first scale 112 corresponds to a single tooth of the first meshing tooth 111. The end face of the second adjusting ring 310 facing the first adjusting ring 110 is provided with a plurality of second scales 312, which are arranged circumferentially along the second adjusting ring 310, and each second scale 312 corresponds to a single tooth of the second meshing tooth 311. The angle adjusting wheel 400 is provided with a first indicator 430 and a second indicator 440, the first indicator 430 indicating the first scale 112 and the second indicator 440 indicating the second scale 312. The required deflection adjustment angle is confirmed by the first indicator 430, the first scale 112, the second indicator 440, and the second scale 312. Regarding the scheme where the first meshing tooth 111 is located on the inner ring of the first adjusting ring 110, assuming the third meshing tooth 410 has 60 teeth and the fourth meshing tooth 420 has 72 teeth, the first scale 112 has clockwise arranged values ​​of -25, -24, ..., -1, 0, 1, ..., 24, 25, and the second scale 312 has clockwise arranged values ​​of -25, -24, ..., -1, 0, 1, ..., 24, 25. Furthermore, in the initial state, the "0" scale on the first adjusting ring 110 corresponds to the "0" scale on the second adjusting ring 310. The adjustment method is as follows (example): 1. Fix the spatial position of the angle adjustment wheel 400, rotate the angle of the connecting arm 300 so that the second indicator 440 (pointer Z) on the end face of the angle adjustment wheel 400 is aligned with "1" in the second scale 312; 2. Fix the spatial position of the assembled angle adjustment wheel 400 and the connecting arm 300, rotate the angle of the motor assembly so that the first indicator 430 (pointer S) on the outer ring of the angle adjustment wheel 400 is aligned with "-1" in the first scale 112, thus completing the connection between the connecting arm 300 and the motor cover 100. At this time, the motor cover 100 rotates counterclockwise by 5 degrees relative to the outer ring of the angle adjustment wheel 400, and at the same time, the connecting arm 300 rotates clockwise by 6 degrees relative to the inner ring of the angle adjustment wheel 400, so that the connecting arm 300 and the motor cover 100 finally rotate relative to each other by 1 degree, completing the fine adjustment of the 1-degree deflection of the connecting arm 300, and finally completing the assembly of the motor 200 and related transmission parts.

[0047] In some embodiments of this invention, the number of teeth on the third meshing tooth 410 is less than the number of teeth on the fourth meshing tooth 420. The smaller number of teeth on the inner ring compared to the outer ring improves the overall force distribution on the angle adjusting wheel 400.

[0048] In some embodiments of this utility model, the third meshing tooth 410 has 60 teeth and the fourth meshing tooth 420 has 72 teeth, or the third meshing tooth 410 has 72 teeth and the fourth meshing tooth 420 has 60 teeth.

[0049] In some embodiments of this utility model, the motor cover 100 has a first perimeter 120, which is arranged circumferentially along the first adjusting ring 110. The connecting arm 300 has a second perimeter 320, which is arranged circumferentially along the second adjusting ring 310. The first perimeter 120 is provided with a first arc-shaped elongated hole 121, and the second perimeter 320 is provided with a first screw mounting hole 321. A first screw passes through the first arc-shaped elongated hole 121 and the first screw mounting hole 321, and / or, the second perimeter 320 is provided with a second arc-shaped elongated hole 322, and the first perimeter 120 is provided with a second screw mounting hole 122. A second screw passes through the second arc-shaped elongated hole 322 and the second screw mounting hole 122. The arc-shaped elongated hole allows the connecting arm 300 and the motor cover 100 to be connected and fastened by screws within a certain deflection angle range.

[0050] In some embodiments of this utility model, the connecting arm 300 includes a main housing 330 and an end cover 340. The driving gear 500 and the driven gear 620 are located in the cavity formed by the main housing 330 and the end cover 340 to prevent the driving gear 500 and the driven gear 620 from coming out. The main housing 330 and the end cover 340 are provided with corresponding through holes. The two ends of the rotating shaft of the driven gear 620 are embedded in the through holes on both sides to realize the rotatable connection between the driven gear 620 and the connecting arm 300.

[0051] In some embodiments of this utility model, a flip cover 700 is also included, which is connected to the swing arm 610. After using the toilet, the user closes the flip cover 700 to cover up unsightly surfaces and prevent the spread of odors. The flip cover 700 is initially horizontal and can be flipped upwards by more than 90 degrees.
