[0038] The utility model proposes a seat ring assembly 100, which is applied to a toilet. The seat ring assembly 100 includes a shell 10, a hollow rotating shaft 20 and a seat ring 30; the shell 10 is provided with two first axial holes 11 spaced apart; one end of the hollow rotating shaft 20 is assembled in the first axial hole 11, and the inside of the hollow rotating shaft 20 is provided with a wire body 200 to pass through; the seat ring 30 includes a main body 31 and two hinged lugs 32 formed on one side of the main body 31, each hinged lug 32 is provided with a second axial hole 321, and the second axial hole 321 cooperates with the hollow rotating shaft 20, and the second axial hole 321 that cooperates with the hollow rotating shaft 20 is provided with a notch 322 toward the opening of the hollow rotating shaft 20, and the notch 322 is used for the wire body 200 to pass through when the hinged lug 32 is assembled on the shell 10.

[0039] The interior of the housing 10 can be used to install structures such as a control circuit board and a water pipe. There are many specific implementations of the first axial hole 11. For example, the top surface of the housing 10 is convexly provided with a mounting seat for the seat ring 30 to be assembled, and the first axial holes 11 are respectively opened on opposite sides of the mounting seat; for another example, the top surface of the housing 10 is provided with a groove, and the first axial hole 11 is set in the groove wall of the groove. There are many implementations of the first axial hole 11, which are set according to specific circumstances.

[0040] In some embodiments of the utility model, two hollow rotating shafts 20 are provided, one end of the two hollow rotating shafts 20 is respectively matched with the two first shaft holes 11, and the other end of the two hollow rotating shafts 20 is respectively connected with the two second shaft holes 321 for damping rotation, and the two second shaft holes 321 are both provided with notches 322 at the openings facing the corresponding hollow rotating shafts 20. In another embodiment of the utility model, one first shaft hole 11 is matched with the hollow rotating shaft 20, and the other first shaft hole 11 is used to match with the driving rotating shaft, so that the driving rotating shaft drives the seat ring 30 to flip.

[0041] The above-mentioned hollow shaft 20 can be rotatably installed in the first axial hole 11, and can also be fixedly installed in the first axial hole 11. Therefore, the end of the hollow shaft 20 close to the first axial hole 11 can be set to a non-circular hollow structure, such as a square, hexagon, etc. There are many specific ways to assemble the hollow shaft 20 in the first axial hole 11, which can be fixed by hot melt, bonding, etc. In some embodiments of the utility model, the outer periphery of the end of the hollow shaft 20 close to the first axial hole 11 can be detachably connected to the inner wall of the shell 10; it can be threaded connection, clamping, etc.; in some embodiments of the utility model, the opposite sides of the hollow shaft 20 are respectively provided with fixing lugs 21, and the fixing lugs 21 are fixed to the inner wall surface of the shell 10. The other end of the hollow shaft 20 is rotatably assembled with the second shaft hole 321 to realize the flipping of the seat ring 30. Preferably, the hollow shaft 20 and the second shaft hole 321 are damped rotationally assembled, so that the seat ring 30 can be flipped to a certain angle and hover, preventing the seat ring 30 from falling due to its own weight, thereby avoiding damage and noise caused by the collision between the seat ring 30 and the toilet bowl body.

[0042] The above-mentioned hinge lugs 32 are generally provided with two, but can also be provided with one. For example, the hinge lugs 32 are provided with second shaft holes 321 on opposite sides, the housing 10 is provided with a groove, and the left and right side walls of the groove are respectively provided with first shaft holes 11, and the two hollow shafts 20 are respectively assembled in the corresponding first shaft holes 11 and second shaft holes 321. When there are two hinge lugs 32, the second shaft holes 321 of the two hinge lugs 32 can be provided on the opposite side of the two, on the opposite side of the two, or on the same side of the two, which is not limited here.

[0043] The wire 200 is connected between the seat 30 and the housing 10. The wire 200 is generally used for conducting electricity. Specifically, in some embodiments of the present invention, a heating device is provided inside the main body 31 of the seat 30, and a control module is provided inside the housing 10. The control module is electrically connected to the heating device through the wire 200 to achieve the heating function of the toilet seat 30 and improve the user's comfort. In other embodiments of the present invention, a pressure sensor is provided inside the seat 30, and a control module is provided inside the housing 10. The control module is electrically connected to the pressure sensor through the wire 200 to achieve the self-flushing function of the toilet after the user gets up from the toilet.

[0044] In the seat ring assembly 100 of the utility model, the hinged lug 32 of the seat ring 30 is concavely provided with a notch 322 on the end surface of one side of the second shaft hole 321 close to the first shaft hole 11. When assembling, the wire harness extending from the second shaft hole 321 of the seat body is first passed through the first shaft hole 11 and the hollow shaft 20 in sequence, and then the notch 322 of the wire harness is kept aligned, and then the first shaft hole 11 and the second shaft hole 321 are aligned, and finally the hollow shaft 20 is assembled into the first shaft hole 11 and the second shaft hole 321 to complete the installation of the seat ring assembly 100. During the assembly process, the wire body 200 is accommodated in the notch 322 between the housing 10 and the hinged lug 32, so that the wire body 200 is not squeezed by the two, and there is no problem of squeezing or jamming the wire. At the same time, the seat ring 30 can be turned over and limited, and the notch 322 will not be exposed after assembly. From the appearance, the seat ring assembly 100 has a small gap and good aesthetics.

[0045] Considering that the notch 322 is too large to be exposed on the top surface of the housing 10, affecting the aesthetics, and the notch 322 is too small to make it difficult for the wire body 200 to align with the notch 322, affecting the convenience of assembly, therefore, in some embodiments of the utility model, the arc of the notch 322 in the circumferential direction of the second shaft hole 321 is not less than 1 / 2π and not more than 2 / 3π. Specifically, it can be 2 / 3π, 3 / 5π, 1 / 2π, etc., which can ensure the aesthetics and assembly convenience of the seat ring assembly 100.

[0046] Furthermore, considering that too small a depth of the notch 322 also affects the convenience of assembly, while too large a depth affects the structural strength of the hinge lug 32, in some embodiments of the utility model, the ratio of the depth of the notch 322 along the axial direction of the first axial hole 11 to the wire diameter of the wire body 200 is not less than 1 / 1 and not more than 2 / 1. Specifically, it can be set to 1 / 1, 1.5 / 1, 1.75 / 1, 2 / 1, etc., to ensure the structural strength of the hinge lug 32 and the convenience of assembly of the seat ring assembly 100.

[0047] In some embodiments of the utility model, the top surface of the housing 10 is provided with two assembly grooves 12, the two assembly grooves 12 are spaced apart in the left-right direction, the two side walls adjacent to the two assembly grooves 12 are provided with first shaft holes 11, the front side walls of the assembly grooves 12 are penetrated, and a hinged lug 32 is assembled in one of the assembly grooves 12. In this way, the toilet has a better flatness and a high aesthetic appearance.

[0048] In some embodiments of the utility model, the bottom wall of the assembly groove 12 is provided with a limiting protrusion 13, and the two end surfaces of the notch 322 in the circumferential direction are respectively used to cooperate with the front and rear sides of the limiting protrusion 13 to limit the rotation angle of the seat ring 30. In this way, the notch 322 can not only avoid the wire body 200 and prevent the wire from being stuck during the assembly process of the seat ring 30, but also limit the rotation angle of the seat ring 30 after the assembly of the seat ring 30 to prevent the seat ring 30 from turning over too much.

[0049] Taking into account that when the seat ring 30 is in the closed state, the force arm between the center of gravity of the seat ring 30 and the rotating shaft is relatively long, and the root of the limiting protrusion 13 is subjected to a relatively large shear force, which may easily cause the limiting protrusion to be squeezed and broken. In some embodiments of the utility model, the front side surface of the limiting protrusion 13 is set as an inclined surface; so that the pressure direction of the limiting protrusion 13 is inclined downward, the shear force of the limiting protrusion 13 in the horizontal direction is relatively small, and the shear strength of the root of the limiting protrusion 13 is higher.

[0050] Considering that the seat ring 30 is mainly supported by the hollow shaft 20 when the seat ring 30 is open, the force between the limiting protrusion 13 and the wall surface of the notch 322 is relatively small, therefore, in other embodiments of the present invention, the rear side surface of the limiting protrusion 13 is set as a vertical surface. This has a good limiting effect.

[0051] Furthermore, in some embodiments of the present invention, the rear side wall of the assembly groove 12 is set to be an arc surface, and the end of the hinge lug 32 is correspondingly set to be an arc shape. In this way, when the seat ring 30 is flipped to any angle, the gap between the hinge lug 32 and the rear side wall of the assembly groove 12 is small.

[0052] Further, in some embodiments of the present invention, the hinged lug 32 includes a fixing portion 323 and an end portion 324, the end portion 324 is assembled in the assembly groove 12, the fixing portion 323 is connected between the end portion 324 and the main body 31, and the fixing portion 323 is located outside the assembly groove 12 and is arranged with increasing thickness in a direction away from the assembly groove 12. In this way, the fixing portion 323 can extend to the bottom surface flush with the bottom surface of the housing 10, which is convenient for fitting with the top surface of the toilet body, and the product consistency is better.

[0053] In some embodiments of the utility model, the housing 10 is provided with two assembly grooves 12, the two assembly grooves 12 are spaced apart in the left-right direction, a first shaft hole 11 is opened on one side wall of the assembly groove 12, and the seat ring 30 is provided with two hinge lugs 32, and one hinge lug 32 is assembled in one assembly groove 12. In this way, under the restriction of the two hinge lugs 32, the seat ring 30 can be prevented from turning left and right, and the seat ring 30 has better stability and higher structural strength.

[0054] Furthermore, in some embodiments of the present invention, the first shaft holes 11 of the two assembly grooves 12 are respectively located on the adjacent side walls of the two assembly grooves 12. In this way, during assembly, it is convenient for the assembler to simultaneously observe the two second shaft holes 321 and take into account the assembly of the two hinged lugs 32, which is conducive to further improving the convenience of assembly.

[0055] The utility model also provides a toilet (not shown), including a barrel body and the seat assembly 100, and a housing 10 connected to the top of the barrel body. The specific structure of the toilet refers to the above embodiment. Since the toilet uses all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0056] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
