DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any way.

[0046] The embodiment of the present application provides a hinge assembly, such as Figure 1 and Figure 2 The hinge assembly 100 shown includes: a hinge body 1 and a driving module 3;

[0047] The hinge body 1 includes a mounting shell 11 having a mounting cavity and a connecting portion connected to the mounting shell 11, wherein the connecting portion is configured to be connected to the flip component;

[0048] The driving module 3 includes a driving body 32 and an output shaft 31 driven to rotate by the driving body 32;

[0049] The driving body 32 is sealedly installed in the mounting shell 11, and the output shaft 31 extends out of the mounting shell 11. The output shaft 31 is configured to be fixed in the circumferential direction with the mounting seat on which the flip component is installed, so that the hinge body 1 can drive the flip component to rotate around the output shaft 31 relative to the mounting seat under the drive of the driving module; wherein, the end of the driving body with the output shaft is sealed from the mounting shell 11 to prevent water vapor from entering the mounting shell 11 from the opening at one end of the mounting shell 11 with the output shaft 31.

[0050] The hinge assembly 100 provided in the embodiment of the present application integrates the drive module 3. Compared with the method of installing the drive module 3 on the mounting base (such as the rear shell body 400 of the toilet), the space occupied by the mounting base can be reduced, which is conducive to improving the appearance. Moreover, in the solution provided in the embodiment of the present application, the drive body 32 of the drive module 3 is installed in the mounting shell 11 of the hinge body 1, which can effectively protect the drive body 32, thereby solving the problem of the service life of the drive module being affected by water vapor.

[0051] In one embodiment, the hinge assembly further includes a torsion spring module 2, which includes a torsion spring seat 22 installed in the mounting shell 11, a torsion spring 24 installed on the torsion spring seat 22, and a connecting shaft 21. The connecting shaft 21 is rotatable relative to the torsion spring seat 22 and one end extends out of the mounting shell 11. One torsion arm of the torsion spring 24 is connected to the torsion spring seat 22, and the other torsion arm is connected to the connecting shaft 21.

[0052] Among them, the output shaft 31 and the connecting shaft 21 are coaxially arranged, and the output shaft 31 and the connecting shaft 21 are both arranged to be connected to the mounting seat and are both arranged to be fixed in the circumferential direction relative to the mounting seat, so that when the driving body 32 drives the output shaft 31 to rotate, the driving body 32 drives the hinge body 1 to rotate relative to the mounting seat.

[0053] When the hinge assembly 100 is used to connect the flip component to the mounting base, the driving body 32 drives the hinge body 1 and the flip component to rotate relative to the mounting base. When the flip component flips downward, the torsion spring 24 can slowly lower the flip component and accumulate momentum. When the flip component flips upward, the accumulated momentum torsion spring 24 can assist the flipping of the flip component upward.

[0054] It is understandable that the hinge assembly 100 may not be provided with the torsion spring module 2 , as long as the driving body 32 can drive the hinge body 1 and the flip component to rotate around the output shaft 31 when the driving module 3 is in operation.

[0055] In some embodiments, the hinge assembly 100 can be used to connect the toilet lid 200 and the rear shell body 400 at the rear end of the toilet, that is, the flip part is the toilet lid 200, and the mounting seat is the rear shell body 400 of the toilet. Of course, the hinge assembly can also be used in other fields.

[0056] like Figure 6-Figure 16 In the illustrated example, the hinge assembly 100, which integrates the driver module 3 and the torsion spring module 2, is mounted on the toilet lid 200. This eliminates the need to mount the driver module and torsion spring module on the toilet's rear housing 400, reducing the space occupied by the mounting base. This improves the overall appearance of the toilet and allows for quick and easy installation of the toilet lid and mounting base. Furthermore, by mounting the torsion spring module 2 and the driver module 3 as a single integrated module within the mounting housing 11, not only is the hinge assembly 100's appearance enhanced, but the assembly efficiency of the various components is also improved, and the components mounted within the mounting housing 11 are also protected from water.

[0057] like Figure 2 and Figure 3 As shown, the mounting shell 11 includes a shell body 111 and a cover body 112. The shell body 111 has a cavity with an opening on one side. The cover body 112 is configured to cover the opening and form the mounting cavity together with the shell body 111. A sealing member 113 is provided between the cover body 112 and the shell body 111 to prevent water from entering the mounting shell 11 through the gap between the cover body 112 and the shell body 111.

[0058] In order to make the driving body 32 sealed in the mounting shell 11, as shown in FIG. Figure 7As shown, a sealing gasket 34 is provided between the end of the driving body 32 of the driving module 3 having the output shaft 31 and the mounting housing 11 to prevent water from entering the mounting housing 11 through the opening at the end of the mounting housing 11 having the output shaft 31. A waterproof cover 25 is provided between the outer peripheral surface of the torsion spring seat 22 and the mounting housing 11 to seal the gap between the torsion spring seat 22 and the mounting housing 11. The waterproof cover 25 prevents water from entering the driving module 3 through the opening at the end of the mounting housing 11 having the connecting shaft 21.

[0059] In some embodiments, a wire passing hole 14 is provided on the mounting shell 11, and a wiring channel 213 connected from one end to the other end is provided on the connecting shaft 21, so that the wiring harness can enter the mounting shell 11 from the wire passing hole 14, and enter the wiring channel 213 from one end of the connecting shaft 21 located in the mounting shell 11 and extend from the other end of the connecting shaft 21 to be connected to the power supply component on the mounting seat; wherein, the hinge assembly 100 also includes a sealing sleeve 15, which is configured to seal the gap between the wire passing hole 14 and the wiring harness passing therethrough, thereby preventing water from entering the mounting shell 11 from the wire passing hole 14.

[0060] The hinge assembly 100 provided in this embodiment is installed on a flip component, such as a toilet lid 200. Figure 6-Figure 8 as well as Figure 11-14 As shown, the wiring harness 301 of the electrical components (such as the display device 300) arranged on the toilet cover 200 can enter the mounting shell 11 of the hinge assembly 100 through the wire hole 14, and then enter the wiring channel 213 from the first end of the connecting shaft 21 and exit from the second end. The wiring harness 301 exiting from the second end can be connected to the controller, and the controller can be installed on the mounting base where the toilet cover 200 is installed (such as the rear shell body 400 of the toilet). Because the connecting shaft 21 is fixed circumferentially relative to the mounting seat when connected to the mounting seat, when the hinge body 1 drives the toilet cover 200 to rotate, the connecting shaft 21 does not rotate. Therefore, when the wiring harness 301 passes through the wiring channel 213 of the connecting shaft 21, it will not rotate with the rotation of the toilet cover 200. This can avoid the problem of wiring harness 301 being worn due to the rotation of the toilet cover 200 and reduce the risk of wire breakage. In addition, since the wiring harness 301 is routed through the wiring channel 213 inside the connecting shaft 21, not only is the wiring convenient, but the wiring harness 301 is also hidden and connected to the controller, which can help improve the appearance of the toilet cover connection.

[0061] Among them, one or more wire holes 14 can be provided as needed. Figure 11-12 There are two wire holes 14 on the display mounting shell 11. The display device 300 on the toilet lid includes a lamp body and a display screen. The wiring harness of the lamp body and the wiring harness of the display screen can each enter the mounting shell 11 through one wire hole 14.

[0062] In one embodiment, the structure of the torsion spring module 2 is as follows: Figure 4-Figure 5 As shown, the first end (left end in the figure) of the connecting shaft 21 is located within the torsion spring seat 22, and the second end (right end in the figure) extends out of the torsion spring seat 22. A wiring channel 213 is formed in the center of the connecting shaft 21. A sealing ring 26 is also provided at the second end of the connecting shaft 21. When the second end of the connecting shaft 21 is connected to the mounting seat, the sealing ring 26 seals the connection between the connecting shaft 21 and the mounting seat. To facilitate installation of the connecting shaft 21 and the torsion spring 24 within the torsion spring seat 22, an installation opening is provided at one end of the torsion spring seat 22, distal from the second end of the connecting shaft 21. This installation opening is fitted with a shaft sleeve cover 23 having an opening 231. The opening 231 corresponds to the first end of the connecting shaft 21, allowing the wiring harness to enter the torsion spring seat 22 through the opening 231, then enter the wiring channel 213 from the first end of the connecting shaft 21, and then extend out from the second end. In order to install the torsion spring 24 on the connecting shaft 21, the connecting shaft 21 forms an annular cavity 212 around the wiring channel 213. One end of the torsion spring 24 extends into the annular cavity 212, and the torsion arm of this end is connected to the connecting shaft 21. The other end of the torsion spring 24 is located outside the annular cavity 212 and is connected to the torsion spring connecting block 27. The torsion spring connecting block 27 is fixed to the torsion spring seat 22.

[0063] In one embodiment, the driving body 32 of the driving module 3 may include a gear box and components such as a motor and a gear assembly located in the gear box, and the output shaft 31 is driven to rotate through the gear assembly. Its specific structure is known to those skilled in the art and will not be described in detail here.

[0064] Because the driving module 3 needs to be connected to the controller through a wiring harness, so that the controller can control the driving module 3, thereby controlling the flipping of the flip component. Figure 13-14 In the example shown, the wiring harness 33 of the driving module 3 may also enter the wiring channel 213 from the first end of the connecting shaft 21 and then extend from the second end.

[0065] The embodiment of the present application also provides a toilet cover device, such as Figures 6-17 As shown, it includes a toilet cover 200 and the hinge assembly 100 as described above, and the connecting portion of the hinge body 1 of the hinge assembly 100 is fixed to the toilet cover 200, that is, the flip component is the toilet cover 200.

[0066] In one embodiment, the electrical components provided on the toilet lid 200 include a display device 300 , and a wiring harness 301 of the display device 300 enters the hinge assembly 100 , enters the wiring channel 213 from the first end of the connecting shaft 21 , and extends from the second end.

[0067] To improve the appearance, the display device 300 is configured to cover the area of ​​the connection portion of the toilet cover 200 connected to the hinge body 1 to prevent fasteners such as screws connecting the connection portion from being exposed to the outside and affecting the appearance of the toilet cover 200.

[0068] Figure 15-16 As shown (combined with Figure 1 and Figure 2 ), the hinge body 1 is provided with two first connection parts 12 and two second connection parts 13 respectively located outside the two first connection parts 12, and the hinge body 1 is connected to the toilet cover 200 through the two first connection parts 12 and the two second connection parts 13.

[0069] Figure 18 and Figure 19 The bottom of the toilet lid 200 is shown to be provided with two slots 201, with the bottom ends of the slots 201 being open. The two first connecting parts 12 are inserted into the slots 201 and fixed by bolts. The inner side of the toilet lid 200 is provided with a raised connecting rib 202, and the two second connecting parts 13 are connected to the connecting rib 202 by bolts. The provision of the connecting rib 202 can strengthen the structure of the toilet lid 200. Moreover, by providing the two first connecting parts 12 and the two connecting parts 13 respectively connected to the toilet lid 200, the connection between the toilet lid 200 and the hinge assembly 100 is firm, so that the hinge assembly 100 can drive the toilet lid 200 to flip stably and reliably.

[0070] Figure 20 The electrical installation body 302 of the display device 300 is fixed to the connecting rib 202 of the toilet lid 200. The electrical installation body 302 includes a decorative portion 3021, which extends to the hinge body 1 and is connected to the hinge body 1. The decorative portion 3021 can cover part of the structure of the hinge body 1, such as the wire hole 14, which can help improve the aesthetics. The first connecting portion 12 and the second connecting portion 13 of the hinge body 1 are installed in the area surrounded by the electrical installation body 302. In this way, when the display screen 303 is installed on the electrical installation body 302, Figure 21 As shown, the locations where the first connecting portion 12 and the second connecting portion 13 are installed are completely covered by the display device 300 .

[0071] The embodiment of the present application also provides a toilet, such as Figure 22 As shown, it includes a toilet body 500, a rear shell body 400 arranged at the rear end of the toilet body 500, and the toilet cover device as described above; the mounting seat is the rear shell body 400, and the output shaft 31 of the hinge assembly 100 is connected to the rear shell body 400, so that the toilet cover 200 flips around the output shaft 31 relative to the rear shell body 400.

[0072] like Figure 22-Figure 24In the illustrated example, the hinge assembly 100 includes a torsion spring assembly 2, an output shaft 31, and a connecting shaft 21 of the torsion spring assembly 2, each mounted on a rear housing body 400.
