[0024] Please see Figure 1 , Figure 1 This is an exploded view of the hinge device provided in this application.

[0025] This application provides a hinge device. For example... Figure 1 As shown, the hinge device of this embodiment includes a metal part 10, an injection-molded part 20, and an injection-molded layer 30. The injection-molded part 20 is disposed at one end of the metal part 10 and is interference-fitted with the metal part 10. The injection-molded layer 30 is disposed on the outer surface of the metal part 10, and at least partially located on the outer side of the injection-molded part 20, forming an interlocking structure with the injection-molded part 20. The injection-molded part 20 and the injection-molded layer 30 enclose the metal part 10. The injection-molded part 20 and the injection-molded layer 30 are formed on the outer surface of the metal part 10 through an injection molding process, thereby enclosing the metal part 10 and physically isolating it from the outside environment, preventing corrosion and rust.

[0026] In an optional embodiment, an injection-molded part 20 is disposed on the metal part 10. The injection-molded part 20 is fixed to the metal part 10 by an interference fit. An injection-molded layer 30 is disposed on the metal part 10, which can enclose the metal part 10. At least part of the injection-molded layer 30 is located on the outside of the injection-molded part 20; that is, the injection-molded layer 30 is partially snapped onto the injection-molded part 20, and the remaining part encloses the metal part 10. Furthermore, an interlocking structure is formed between the injection-molded part 20 and the injection-molded layer 30, thereby fixing the injection-molded part 20 and the injection-molded layer 30 without the need for other devices to fix the injection-molded part 20 and the injection-molded layer 30 to the surface of the metal part 10.

[0027] The injection molded part 20 is disposed at one end of the metal part 10. The injection molded part 20 can be connected to external components. That is, the injection molded part 20 is disposed on the metal part 10, which can protect the metal part 10 without affecting its function.

[0028] In this embodiment, the injection molded part 20 and the injection molded layer 30 are formed on the outer surface of the metal part 10 by injection molding. When forming the injection molded part 20 and the injection molded layer 30 on the surface of the metal part 10, the metal part 10 can be placed in a plastic mold and positioned. Then, a high-strength injection molding material can be injected into the mold to form the injection molded part 20 and the injection molded layer 30 on the surface of the metal part 10. The material used for the injection molded part 20 and the injection molded layer 30 can be a polyamide composite material formed from polyamide and glass fiber. In other embodiments, other high-strength materials can also be used, and this application does not specifically limit their use.

[0029] In an optional embodiment, the injection-molded part 20 and injection-molded layer 30 on the surface of the metal part 10 can be formed using a multi-injection direction. For example, the injection-molded part 20 can be pre-molded on the metal part 10, and then the injection-molded layer 30 can be formed on the metal part 10. When forming the hinge device, the metal part 10 can be positioned in a plastic mold, and then a first injection molding is performed to form the injection-molded part 20 on the metal part 10. The injection-molded part 20 can be interference-fitted with the metal part 10 to prevent the injection-molded part 20 from separating from the metal part 10. After the injection-molded part 20 is formed on the metal part 10, a second injection molding can be performed on the metal part 10. The second injection molding can cover the remaining area of ​​the metal part 10 except for the area covered by the injection-molded part 20. The injection-molded part 20 and injection-molded layer 30 formed by the first and second injection molding can be made of the same material, or the second injection molding can also use other materials according to appearance requirements. This application does not make specific limitations here. For example, the second part can be made of PP (Polypropylene) material, that is, the injection molded part 20 can be made of polyamide composite material, and the injection layer 30 can be made of polypropylene material.

[0030] In the above embodiment, by providing an injection molded part 20 that is interference-fitted with the metal part 10 at one end of the metal part 10, and providing an injection molded layer 30 that is at least partially located outside the injection molded part 20 on the outer surface of the metal part 10 and forming an interlocking structure with the injection molded part 20, the injection molded part 20 and the injection molded layer 30 can wrap around the metal part 10, thereby protecting the metal part 10 and preventing corrosion and rust.

[0031] In an optional embodiment, such as Figure 2As shown, the metal part 10 includes a pivot portion 11, a bending portion 12, and a fixing portion 13 connected in sequence. The pivot portion 11 is located at one end of the bending portion 12, and the fixing portion 13 is located at the other end of the bending portion 12. The pivot portion 11 and the fixing portion 13 are set at a preset angle to the bending portion 12. The injection molded part 20 is disposed at the end of the pivot portion away from the bending portion 12. Since the pivot portion 11 and the fixing portion 13 are set at a preset angle to the bending portion 12, when the injection molded part 20 is injection molded onto the metal part 10, the injection molded part 20 can be injection molded onto the pivot portion 11. When the injection molded part 20 is injection molded onto the pivot portion 11, the injection molded part 20 can be interference-fitted with the pivot portion 11, thereby preventing the injection molded part 20 from separating from the metal part 10 after it has been injection molded onto the metal part 10.

[0032] In this embodiment, the bending portion 12 has a certain curvature, and the pivot portion 11 and the fixing portion 13 are set at a preset angle to the bending portion 12. That is, when the injection layer 30 is formed on the metal part 10, the injection layer 30 can be fixed by the bending portion 12, the pivot portion 11 and the fixing portion 13, thereby preventing the injection layer 30 from separating from the metal part 10 after the injection layer 30 is formed on the metal part 10.

[0033] In an optional embodiment, such as Figure 3 As shown, the injection-molded layer 30 includes a first injection-molded portion 31 and a second injection-molded portion 32. The first injection-molded portion 31 is disposed on the outer surface of the bent portion 12, and the second injection-molded portion 32 is disposed on the outer surface of the fixed portion 13. The first injection-molded portion 31 and the second injection-molded portion 32 can be integrally formed, that is, after the injection-molded part 20 is formed on the metal part 10, the injection-molded layer 30 is then integrally formed on the metal part 10.

[0034] In this embodiment, the first injection molding part 31 and the second injection molding part 32 are detachably connected. A snap-fit ​​member 311 is provided at one end of the first injection molding part 31 near the fixing part 13, and a snap-fit ​​member 321 is provided at one end of the second injection molding part 32 near the bending part 12. The snap-fit ​​member 311 is connected to the snap-fit ​​member 321. That is, the injection molding layer 30 can be formed by multiple injection molding processes. Specifically, as... Figure 4 As shown, when the injection molded part 20 is formed, the second injection molded part 32 can be formed simultaneously. That is, when the injection molded part 20 is provided on the metal part 10, the second injection molded part 32 is simultaneously provided on the metal part 10. After the injection molded part 20 and the second injection molded part 32 are formed on the metal part 10, as shown... Figure 5As shown, a first injection molding portion 31 is then provided on the metal part 10. A snap-fit ​​member 311 is provided at one end of the first injection molding portion 31 near the fixing portion 13, and a snap-fit ​​member 321 is provided at one end of the second injection molding portion 32 near the bending portion 12. That is, when the second injection molding portion 32 is formed by the first injection molding, a snap-fit ​​member 321 is provided at one end of the second injection molding portion 32 near the bending portion 12, so as to facilitate fixing the first injection molding portion 31 and the second injection molding portion 32 when the first injection molding portion 31 is formed.

[0035] After the second injection part 32 is formed on the metal part 10, since the second injection part 32 has a snap-fit ​​member 321, when the first injection part 31 is formed subsequently, the injection material can be directly injected into the snap-fit ​​member 321. After fixing, a snap-fit ​​member 311 is formed, so that the snap-fit ​​member 311 and the snap-fit ​​member 321 are snapped and fixed to fix the first injection part 31 and the second injection part 32 to form the injection layer 30.

[0036] In an optional embodiment, such as Figure 2 As shown, a groove 111 is provided on the rotating shaft portion 11, and the injection molded part 20 is connected to the rotating shaft portion 11 via the groove 111. The groove 111 on the rotating shaft portion 11 allows the injection molded part 20 to be fixed in place during injection molding, thus preventing the injection molded part 20 from disengaging from the rotating shaft portion 11. A through hole 21 is provided at the end of the injection molded part 20 away from the rotating shaft portion 11. The through hole 21 is used for connection to external components, allowing the metal part 10 to be fixed to external components via the injection molded part 20.

[0037] In an optional embodiment, such as Figure 4 As shown, an annular groove 22 is provided on the outer surface of the injection molded part 20, and the injection molded layer 30 is connected to the injection molded part 20 through the annular groove 22. During the first injection molding of the injection molded part 20, the annular groove 22 can be provided at the end of the injection molded part 20 away from the through hole 21. Then, during the second injection molding of the injection molded layer 30, the injection molded layer 30 can wrap around the annular groove 22, thereby fixing the injection molded part 20 and the injection molded layer 30 together and preventing the injection molded layer 30 from detaching from the injection molded part 20. Furthermore, the method of forming the annular groove 22 can effectively prevent external liquids from entering the interior of the injection molded part 20 and the injection molded layer 30, thereby preventing corrosion of the metal part 10.

[0038] This application also provides a smart toilet, which includes: a hinge device 50 and a toilet body 40, wherein the hinge device 50 is the hinge device 50 of any of the above embodiments.

[0039] In an optional embodiment, the toilet body 40 includes a first housing 41 and a second housing 42. The through hole 21 of the injection-molded part 20 is hinged to the first housing 41, and the fixing part 13 of the hinge device 50 is connected to the second housing 42, so that the first housing 41 and the second housing 42 are hinged together by the hinge device 50. The hinge device 50 is disposed between the first housing 41 and the second housing 42. When using the smart toilet, it is necessary to open the first housing 41 and the second housing 42, that is, the second housing 42 can rotate relative to the first housing 41. Specifically, when the hinge device 50 is disposed on the toilet body 40, the through hole 21 on the plastic part can be connected to the first housing 41, and the fixing part 13 of the hinge device 50 can be connected to the second housing 42, so that when the second housing 42 is opened, the second housing 42 can rotate relative to the first housing 41 under the action of the hinge device 50.

[0040] In this embodiment, the fixing part 13 on the hinge device 50 may be provided with a number of holes. When fixing the fixing part 13 on the hinge device 50 to the second housing 42, screws may be used to fix the fixing part 13 to the second housing 42, or other fixing methods may be used, such as pin fixing, etc. This application does not make specific limitations here.

[0041] In this embodiment, two hinge devices 50 may be provided between the first housing 41 and the second housing 42, that is, they may be symmetrically arranged between the first housing 41 and the second housing 42, thereby hinged between the first housing 41 and the second housing 42. In other embodiments, three or four hinge devices may be provided between the first housing 41 and the second housing 42, which is not specifically limited here.

[0042] In an optional embodiment, a receiving space (not shown) is formed within the first housing 41, and a damping element (not shown) is provided on the inner sidewall of the first housing 41 within the receiving space. The through hole 21 is connected to the damping element, and the hinge device 50 is at least partially located within the receiving space. With the receiving space formed within the first housing 41, when the hinge device 50 is mounted on the toilet body 40, the hinge device 50 can be at least partially located within the receiving space. Specifically, when the first housing 41 and the second housing 42 are closed, the hinge device 50 can be accommodated within the receiving space. When the second housing 42 is rotated relative to the first housing 41, i.e., when the second housing 42 is opened, the hinge device 50 can extend from the receiving space.

[0043] In this embodiment, when the hinge device 50 is fixed on the first housing 41, the through hole 21 on the injection molded part 20 can be fixed on the damping member. When it is necessary to open the second housing 42, the second housing 42 can be pushed, so that the hinge device 50 rotates relative to the damping member. Due to the presence of the damping member, when the second housing 42 is opened, the second housing 42 is prevented from retracting to the closed state of the first housing 41.

[0044] In an optional embodiment, the first housing 41 is the seat cover of the smart toilet, and the second housing 42 is the back cover of the smart toilet. When using the smart toilet, the second housing 42 can be moved, causing the hinge device 50 to rotate relative to the first housing 41. Specifically, the hinge device extends from the receiving space of the first housing 41, thus opening the second housing 42 relative to the first housing 41. After using the smart toilet, the second housing 42, i.e., the back cover, can be closed, causing the hinge device 50 to close the second housing 42 relative to the first housing 41. At this time, the hinge device 50 retracts into the receiving space.

[0045] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
