[0026] In the description of the present invention, the terms "upper", "lower", "left", "right", "front", "rear" and other position or positional relationships are based on the positions or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore should not be construed as a limitation to the present invention.

[0027] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0028] Referring to Figures 1 to 6 As shown, a toilet seat assembly provided in this embodiment includes a cover plate 11, a seat ring 12, a sub-seat ring 13, a fixed support 40 and two groups of connecting shafts 20. The seat ring 12 has two coaxial shaft holes 121. The two shaft holes 121 of the seat ring 12 are respectively assembled with two groups of connecting shafts 20 and are hinged to the cover plate 11 through the two groups of connecting shafts 20. The fixed support 40 is fixedly connected to the two groups of connecting shafts 20. In this way, the hinged setting of the cover plate 11 and the seat ring 12 is realized.

[0029] The seat ring 12 further has an insertion space 122 located between the two shaft holes 121, and further includes two mounting shafts 30. The two mounting shafts 30 are respectively detachably assembled on the two groups of connecting shafts 20 and form circumferential limits with the connecting shafts 20, that is, the left mounting shaft 30 is connected to the left connecting shaft 20, and the right mounting shaft 30 is connected to the right connecting shaft 20. In this way, the mounting shaft 30 is fixed in its circumferential direction.

[0030] The two mounting shafts 30 have mounting sections 31 exposed outside the insertion space 122. A plugging notch 132 with a minimum diameter adapted to the mounting section 31 is formed on the shaft sleeve 131 of the sub-seat ring 13. When the plugging notch 132 of the sub-seat ring 13 corresponds to the position of the minimum diameter of the mounting section 31, the mounting section 31 of the mounting shaft 31 can be inserted or pulled out.

[0031] In this embodiment, the cross-section of the installation section 31 is in a runway shape, which is equivalent to the structure obtained by cutting off two symmetrical "D" - shaped parts from a circle; the minimum diameter of the installation section 31 is the distance between the two straight cutting surfaces 311. The size of the insertion notch 132 of the sub - seat ring 13 is adapted to the minimum diameter of the installation section 31, that is, the size of the insertion notch 132 of the sub - seat ring 13 is slightly larger than the minimum diameter of the installation section 31 but much smaller than the maximum size of the installation section 31. When it is necessary to install or disassemble the sub - seat ring 13, rotate the sub - seat ring 13 to the position where its insertion notch 132 corresponds to the minimum diameter of the installation section 31, and then the installation and disassembly operations can be easily achieved, while in other positions, the stable assembly of the sub - seat ring 13 is ensured; thus, the installation and disassembly operations of the sub - seat ring 13 do not adopt the interference fit method, and even frequent installation and disassembly operations will not damage the sub - seat ring 13, ensuring the service life of the product.

[0032] Specifically, after the sub - seat ring 13 is assembled, it is located between the cover plate 11 and the seat ring 12.

[0033] Meanwhile, the two installation shafts 30 are respectively detachably assembled on two sets of connecting shafts 20 and form circumferential limits with the connecting shafts 20. If the sub - seat ring 13 is not used for a long time, the two installation shafts 30 can also be removed together to avoid the pollution of the exposed installation shafts 30 and the difficulty of cleaning, and also maintain the aesthetics of the product well. Specifically, the way to remove the installation shaft 30 is to pull out the installation shaft 30 in the direction towards the center of the insertion space 122. After removing the installation shaft 30, the shaft hole 121 of the seat ring 12 can be blocked by a suitable plug.

[0034] The cross - section of the above - mentioned installation section 31 adopts a runway - shaped structure. After being assembled into the bushing 131 of the sub - seat ring 13, the arc segments on both sides can cooperate with the bushing 131 of the sub - seat ring 13 to achieve the stable flipping of the sub - seat ring 13. Of course, in other embodiments, the cross - section of the installation section 31 can also be a rectangular structure, a "D" - shaped structure, etc.

[0035] Further, in this embodiment, a first slow-falling shaft 24 is further assembled in the bushing 131 of the sub-seat ring 13. The first slow-falling shaft 24 has a limiting convex portion 25 corresponding to the insertion notch 132. At least one of the mounting shafts 30 is provided with a limiting notch 312 on the mounting section 31. In this embodiment, the two mounting shafts 30 have the same structure and unified fittings, that is, the mounting sections 31 of the two mounting shafts 30 are both provided with limiting notches 312. The first slow-falling shaft 24 can be matched with one of the mounting shafts 30. When the insertion notch 132 of the sub-seat ring 13 is inserted into the mounting section 31, the limiting convex portion 25 of the first slow-falling shaft 24 is synchronously inserted into the limiting notch 312 of the mounting shaft 30 and forms circumferential limitation with the mounting shaft 30. In this way, the slow descent of the sub-seat ring 13 can be realized. Of course, in other embodiments, the structure of the first slow-falling shaft 24 may not be adopted.

[0036] Specifically, the mounting shaft 30 includes a limiting convex column section 33, a cylindrical section 32 and the mounting section 31 connected in sequence. The limiting convex column section 33 is detachably inserted into the connecting shaft 20 and forms circumferential limitation with the connecting shaft 20. The cylindrical section 32 passes through the shaft hole 121 of the seat ring 12. The mounting section 31 is exposed in the insertion space 122 of the seat ring 12. In this way, the specific assembly of the mounting shaft 30 is realized. Of course, in other embodiments, the structure of the mounting shaft 30 is not limited to this. For example, the limiting convex column section 33 is replaced with a limiting groove hole provided in the cylindrical section 32, and the connecting shaft 20 is provided with a convex column and inserted into the limiting groove hole of the cylindrical section 32, which can also realize the circumferential limiting cooperation between the connecting shaft 20 and the mounting shaft 30.

[0037] An elastic member 23 is provided between the connecting shaft 20 and the mounting shaft 30. The elastic member 23 is specifically a spring. The elastic member 23 applies an elastic force to the mounting shaft 30 in the direction towards the insertion space 122. The elastic force applied by the elastic member 23 to the mounting shaft 30 makes it easier to remove the mounting shaft 30. At the same time, an outward elastic force is applied to the connecting shaft 20 to ensure the assembly of the connecting shaft 20 and the cover plate 11.

[0038] Further, two fixing supports 40 are provided. The two fixing supports 40 are respectively fixedly matched with two groups of connecting shafts 20. Specifically, the fixing support 40 includes a mounting base 41 and a plug post 42 connecting the mounting base 41. A plug hole is provided on the connecting shaft 20. The fixing support 40 is fixedly inserted into the plug hole of the connecting shaft 20 through the plug post 42. Of course, in other embodiments, the fixing support 40 can also be an integral structure, that is, one fixing support 40 fixedly connects two groups of connecting shafts 20 at the same time.

[0039] Furthermore, when the sub-seat ring 13 is rotated to a position perpendicular to the mounting base 41 of the fixed support 40, that is, after being installed on the toilet, when the sub-seat ring 13 is rotated to a vertical position, the insertion notch 132 of the sub-seat ring 13 corresponds to the minimum diameter position of the mounting section 31, thereby realizing the assembly and disassembly of the sub-seat ring 13. In this way, the sub-seat ring 13 is prevented from falling off during use. Of course, in other embodiments, the sub-seat ring 13 can also be rotated to an inclined position of 45° or 60° to the toilet seat surface, and the insertion notch 132 of the sub-seat ring 13 corresponds to the minimum diameter position of the mounting section 31.

[0040] Furthermore, both groups of connecting shafts 20 include a fixed shaft section 21 and a second slow-fall shaft 22 connected to each other; the fixed support 40 is fixedly connected to the fixed shaft section 21; the installation shaft 30 forms a circumferential limit with the fixed shaft section 21; that is, the fixed support 40, the installation shaft 30 and the fixed shaft section 21 form a fixed whole. In the two groups of connecting shafts 20, the second slow-fall shaft 22 of one group of connecting shafts 20 forms a circumferential limit with the seat ring 12, thereby realizing the slow descent of the seat ring 12; the second slow-fall shaft 22 of the other group of connecting shafts 20 forms a circumferential limit with the cover plate 11, thereby realizing the slow descent of the cover plate 11. Of course, in other embodiments, the two groups of connecting shafts 20 can also be structures with only the fixed shaft section 21, that is, the seat ring 12 and the cover plate 11 do not have the slow descent function.

[0041] Furthermore, in order to better realize going to the toilet at night, in this embodiment, the cover plate 11 is equipped with a power box 113, a light source box 112 and a light guide strip 111; the side of the cover plate 11 facing the seat ring 12 is defined as the inner side, and the side away from the inner side is defined as the outer side; the outer side of the cover plate 11 is provided with an embedding groove and a mounting opening connected to the embedding groove and extending to the inner side; the light guide strip 111 is embedded in the embedding groove, and the light source box 12 is assembled in the mounting opening, and the light source box 12 is provided with a controller, an ambient light detection module, a sound sensor module and a light source; the output ends of the ambient light detection module and the sound sensor module are respectively connected to the input end of the controller, and the control output end of the controller is connected to the light source; the light emitting surface of the light source faces the light guide strip 111; the power box 113 is assembled on the inner side of the cover plate 11 and provides power to the light source box 12.

[0042] By using dual detection of the ambient light detection module and the sound sensor module, the controller can be designed to control the light source to emit light only when both the light detection and the sound detection meet the set conditions. In this way, it can effectively avoid emitting light during the day or when no one is around and causing energy consumption.

[0043] One application method of this solution is as follows: The toilet lid assembly is applied to a toilet. When not in use, the toilet lid assembly generally covers the toilet bowl part. At this time, the outer side of the cover plate 11 is set upward, which can well sense the ambient light. The ambient light detection module detects the light intensity of the environment and outputs it to the controller, and the sound sensing module detects the vibration sound wave and outputs it to the controller; When going to the toilet at night, only when the light intensity is lower than the set value and vibration is sensed at the same time, the controller controls the light source to emit light. The light emitted by the light source enters the light guide bar 111, and the light guide bar 111 conducts the light and emits it outward, so as to achieve good lighting and clearly indicate the position of the toilet; It is convenient for users to achieve basic lighting without turning on the light at night. When the user leaves, the sound sensing module does not detect the sound wave, and the controller controls the light source not to work.

[0044] Furthermore, the controller, the ambient light detection module, and the sound sensing module all adopt existing technology products. For example, the controller adopts a CPU controller, the ambient light detection module can adopt a sensor with a photosensitive resistor, and the sound sensing module adopts a vibration sensor, etc. The specific connection structure and installation method are already mastered by those skilled in the art and will not be elaborated here.

[0045] Although the present utility model is specifically shown and introduced in combination with the preferred implementation, those skilled in the art should understand that various changes can be made to the present utility model in terms of form and details without departing from the spirit and scope of the present utility model defined by the appended claims, and all of them are within the protection scope of the present utility model.
