[0001] The utility model relates to the technical field of door and window fittings, and more specifically, to a hinge assembly and a shower room. Background Art

[0002] In the prior art, for a door connected by an outward-opening hinge assembly, during the closing process of the door, the hinge assembly cannot automatically close at a small angle, and the operator needs to push or pull the door by hand to close it. Moreover, the hinge assembly of the prior art has the phenomenon of incomplete closing, resulting in poor sealing of the door after it is closed, thus affecting the user experience.

[0003] Applying the outward-opening hinge assembly to the field of shower rooms, if the hinge assembly is not closed in place, it will cause the door of the shower room not to close tightly. When the user takes a shower, the water in the shower room is likely to flow outside the shower room, making the shower room unable to achieve the effect of separating dry and wet areas.

[0004] An embodiment of the utility model provides a hinge assembly and a shower room. The hinge assembly includes a first hinge seat, a second hinge seat and a reset assembly. A reset groove is provided at the second hinge portion of the second hinge seat. The elastic assembly can apply an elastic force to the reset fitting so that the reset fitting abuts against the end of the second hinge portion provided with the reset groove. When the second hinge seat rotates relative to the first hinge seat to the closed position, the reset fitting enters the reset groove under the drive of the elastic assembly. Therefore, the hinge assembly of this application has the advantages of automatic closing at a small angle, complete closing and accurate reset.

[0014] The technical effects of the hinge assembly according to the embodiment of the present invention are as follows:

[0015] In the hinge assembly according to the embodiment of the present application, the second hinge portion is configured as a cylinder coaxial with the first rotation axis of the hinge assembly. A reset groove is provided at the axial end of the second hinge portion. The reset assembly can rotate relative to the second hinge seat around the first rotation axis together with the first hinge seat. The reset assembly includes a reset mating part and an elastic component. The reset mating part can be driven by the elastic component to press against the end face of the second hinge portion provided with the reset groove. Thus, when the second hinge seat rotates relative to the first hinge seat to the closed position, the reset mating part can enter the reset groove under the drive of the elastic component. Therefore, the hinge assembly of the present application can achieve: a small-angle automatic closing action of the hinge assembly near the closed position. Moreover, when the hinge assembly of the present application is in the closed state, the elastic component applies an elastic force to the reset mating part, so that the reset mating part remains pressed against the inner wall surface of the reset groove, making it difficult for the reset mating part to escape from the reset groove, thereby ensuring that the hinge assembly is closed in place and reset accurately.

[0035] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined arbitrarily with each other.

[0036] Please refer to the Figure 1 to the Figure 14 structural schematic diagram of the hinge assembly 100 of the embodiment of the present application shown in the accompanying drawings. As Figure 1 , Figures 6 - 8 and Figure 10 shown, the embodiment of the present application provides a hinge assembly 100, including a first hinge seat 1, a second hinge seat 2 and a reset assembly 4; the first hinge seat 1 includes a first hinge part 1-1; the second hinge seat 2 includes a second hinge part 21 hinged to the first hinge part 1-1, the second hinge part 21 is configured as a cylinder coaxial with the first rotation axis 3 of the hinge assembly 100, and a reset groove 211 is provided at the axial end of the second hinge part 21; the reset assembly 4 is arranged to be able to rotate relative to the second hinge seat 2 together with the first hinge seat 1 around the first rotation axis 3; the reset assembly 4 includes a reset fitting 41 and an elastic assembly 42; the reset fitting 41 abuts against the end of the second hinge part 21 provided with the reset groove 211; the elastic assembly 42 is arranged to apply an elastic force to the reset fitting 41 so that the reset fitting 41 abuts against the end of the second hinge part 21 provided with the reset groove 211; wherein, the reset fitting 41 is configured as a rolling body, and the rolling body is in rolling connection with the elastic assembly 42; when the second hinge seat 2 rotates relative to the first hinge seat 1 to the closed position, the reset fitting 41 enters the reset groove 211.

[0037] In the prior art, when a door is connected by an outward-opening hinge assembly, the hinge assembly cannot automatically close at a small angle during the door closing process, and the operator needs to push or pull the door manually to close it. In addition, the hinge assembly of the prior art may not close properly, resulting in poor sealing of the door after closing, and poor user experience.

[0038] In the hinge assembly 100 provided in the embodiment of the present application, the second hinged portion 21 is constructed as a cylinder coaxial with the first rotation axis 3 of the hinge assembly 100, and a reset groove 211 is provided at the axial end of the second hinged portion 21. The reset assembly 4 can rotate with the first hinge seat 1 relative to the second hinge seat 2 around the first rotation axis 3. The reset assembly 4 includes a reset fitting 41 and an elastic component 42. The reset fitting 41 can abut against the end surface of the second hinged portion 21 provided with the reset groove 211 under the elastic force of the elastic component 42. In this way, when the second hinge seat 2 rotates to the closed position relative to the first hinge seat 1, the reset fitting 41 can enter the reset groove 211 under the elastic force of the elastic component 42. Therefore, the hinge assembly 100 of the present application can realize the small-angle automatic closing action of the hinge assembly 100 near the closed position. Furthermore, when the hinge assembly 100 of the present application is in a closed state, the elastic assembly 42 applies elastic force to the reset fitting 41, so that the reset fitting 41 remains pressed against the inner wall surface of the reset groove 211, and the reset fitting 41 is difficult to escape from the reset groove 211, thereby ensuring that the hinge assembly 100 is closed in place and reset accurately.

[0039] Furthermore, the hinge assembly 100 of the present application sets the reset groove 211 at the axial end of the second hinge part 21, so that the reset fitting 41 can also be set at the axial end of the second hinge part 21, so that the thickness dimension of the hinge assembly 100 can be designed to be smaller, so that the hinge assembly 100 occupies a smaller space.

[0040] In addition, the reset fitting 41 is configured as a rolling body, and the rolling body can be rollingly connected to the elastic component 42, so that the reset fitting 41 and the end of the second hinge part 21 with the reset groove 211 are in rolling contact. Compared with the sliding contact matching method, the rolling contact matching method of the hinge assembly 100 of the embodiment of the present application can reduce the friction and wear damage between the axial ends of the reset fitting 41 and the second hinge part 21, thereby improving the service life of the hinge assembly 100.

[0041] When the hinge assembly 100 of the present application is applied to the door of a shower room, since the hinge assembly 100 of the present application can automatically close at a small angle and the closing and resetting are accurate, the shower room door connected to the hinge assembly 100 of the present application can be closed tighter and the door has better sealing performance. For a shower room using the hinge assembly 100 of the present application, it can effectively prevent the water flow from the shower spray in the shower room from flowing outside the shower room, so that the effect of separating dry and wet areas in the shower room is better.

[0042] In an exemplary embodiment, as Figure 6 , Figure 9 , Figure 10 , Figure 12 and Figure 14 shown, the rolling element is a ball or a roller; the elastic assembly 42 includes a swing rod 421 and an elastic member 422.

[0043] The swing rod 421 is rotatably connected to the first hinge seat 1. The swing rod 421 rotates relative to the first hinge seat 1 about the second rotation axis 5. The second rotation axis 5 is perpendicular to the first rotation axis 3. The rolling element is located between the swing rod 421 and the reset groove 211. A receiving groove 4211 for partially receiving the rolling element is provided on the side wall of the swing rod 421 facing the rolling element.

[0044] The elastic member 422 abuts against the swing rod 421 and is configured to apply an elastic force to the swing rod 421 so that the rolling element abuts against the end of the second hinge portion 21 provided with the reset groove 211.

[0045] Specifically, as the first hinge seat 1 and the second hinge seat 2 rotate relative to each other, the rolling element in the receiving groove 4211 of the swing rod 421 can rotate relative to the first hinge seat 1 about the second rotation axis 5 together with the swing rod 421. Since the elastic member 422 applies an elastic force to the swing rod 421, the rolling element is kept in contact with the end of the second hinge portion 21 provided with the reset groove 211. In Figure 9 the embodiment shown, the rolling element is configured as a ball, and the rolling element of the present application can also be configured as a roller.

[0046] It can be understood that the reset groove 211 of the present application can be provided as one or more. For example, reset grooves 211 can be provided at both ends in the axial direction of the second hinge portion 21, or a reset groove 211 can be provided only at one end in the axial direction of the second hinge portion 21.

[0047] The reset assembly 4 of the present application can be specifically configured in a variety of structural forms. For example, the end of the elastic member 422 that abuts against the swing rod 421 can be arranged on the side of the second rotation axis 5 away from the receiving groove 4211; the end of the elastic member 422 that abuts against the swing rod 421 can also be arranged on the same side of the second rotation axis 5 together with the receiving groove 4211; the elastic member 422 and the rolling body can be distributed on the same side in the length extension direction of the swing rod 421; the elastic member 422 and the rolling body can be distributed on both sides in the length extension direction of the swing rod 421.

[0048] The structural forms of the above-mentioned reset groove 211 and the reset assembly 4 are all within the protection scope of the present application.

[0049] In an exemplary embodiment, as Figure 7 、 Figure 10 、 Figure 12 and Figure 14 shown, reset grooves 211 are provided at both axial ends of the second hinge portion 21, and the two reset grooves 211 are aligned axially on the second hinge portion 21.

[0050] Two reset mating members 41 are provided, and the two reset mating members 41 respectively abut against the two axial ends of the second hinge portion 21;

[0051] Two swing rods 421 are provided, and the two swing rods 421 each include a first end 4212 close to the reset groove 211 and a second end 4213 away from the reset groove 211. The two second rotation axes 5 are both located between the first end 4212 and the second end 4213 of their respective swing rods 421, and the two first ends 4212 are respectively arranged on the side of the corresponding reset mating member 41 facing away from the second hinge portion 21.

[0052] The elastic member 422 is clamped between the two second ends 4213 and is in a compressed state.

[0053] Specifically, reset grooves 211 are provided at both axial ends of the second hinge portion 21, and the two reset grooves 211 are aligned axially on the second hinge portion 21. Two sets of reset mating members 41 and swing rods 421 are provided, and each set of reset mating members 41 and swing rods 421 is correspondingly arranged with one axial end of the second hinge portion 21. In this way, for the hinge assembly 100 of the present application, the reset assembly 4 can perform reset actions from the two axial ends of the second hinge portion 21, making the reset closing action process of the hinge assembly 100 of the present application more stable, not prone to swaying during the reset closing process, and the reset closing position of the hinge assembly 100 more accurate and reliable.

[0054] For the hinge assembly 100 of the present application, an elastic member 422 in a compressed state is clamped between two second ends 4213, so that the two ends of one elastic member 422 can respectively drive two swing rods 421. This can simplify the structural design of the reset assembly 4 and save the space occupied by the reset assembly 4. By using the two ends of one elastic member 422 in a compressed state to respectively drive two swing rods 421, the two swing rods 421 can swing synchronously, enabling the two reset mating members 41 to act synchronously.

[0055] In an exemplary embodiment, as Figure 7 shown, in the direction from the bottom of the reset groove 211 to the opening of the reset groove 211, its width has a tendency to increase.

[0056] For the part of the end face of the second hinge portion 21 in the axial direction other than the reset groove 211, it is set as a plane 212 perpendicular to the axial direction of the second hinge portion 21; between the plane 212 and the side wall surface of the reset groove 211 is a smoothly transitioning curved surface; when the second hinge seat 2 reciprocally rotates relative to the first hinge seat 1, the rolling body reciprocally rolls between the wall surface of the reset groove 211 and the plane 212.

[0057] Specifically, in the embodiment as Figure 10 shown, the hinge assembly 100 is in the closed position, and at this time, the end of the rolling body along the axial direction of the second hinge portion 21 has rolled into the interior of the reset groove 211. As Figures 11 to 12 shown in the embodiment, the hinge assembly 100 is in a partially open position, and at this time, the end of the rolling body along the axial direction of the second hinge portion 21 rolls to the position of the plane 212. As Figures 13 to 14 shown in the embodiment, the hinge assembly 100 is in the fully open position, and at this time, the end of the rolling body along the axial direction of the second hinge portion 21 rolls to a position on the plane 212 that is farther from the reset groove 211.

[0058] In the direction from the bottom of the reset groove 211 to the opening of the reset groove 211, its width has a tendency to increase, and this structural design is beneficial for the rolling body to roll into the interior of the reset groove 211. The between the plane 212 and the side wall surface of the reset groove 211 is set as a smoothly transitioning curved surface, and this structural design is beneficial for the rolling body to smoothly roll between the plane 212 and the reset groove 211.

[0059] In an exemplary embodiment, as Figure 7 shown, a protruding portion 213 adjacent to the reset groove 211 is formed by radially protruding outward on the outer peripheral surface of the second hinge portion 21.

[0060] The end face 2131 of the protruding portion 213 is a plane, and a smoothly transitioning curved surface is provided between it and the side wall surface of the reset groove 211.

[0061] Specifically, a radially outwardly protruding portion 213 adjacent to the reset groove 211 is formed on the outer peripheral surface of the second hinge portion 21. The end surface 2131 of the protruding portion 213 forms a part of the plane 212, so that the area of the end surface 2131 can be larger, which is beneficial to the rolling motion of the rolling elements on the end surface 2131. Moreover, the protruding portion 213 can also prevent the rolling elements from coming out of the reset groove 211, making the closing and resetting of the hinge assembly 100 of the present application more stable and reliable. In addition, the protruding portion 213 can limit the range of the relative rotation angle between the first hinge seat 1 and the second hinge seat 2.

[0062] In an exemplary embodiment, as Figure 6 , Figure 9 and Figure 14 shown, the elastic member 422 is a spring, and a positioning protrusion 4214 inserted into the spring is provided on the side of the second end 4213 of the swing rod 421 facing the spring.

[0063] Specifically, a positioning protrusion 4214 inserted into the spring is provided on the side of the second end 4213 of the swing rod 421 facing the spring. The positioning protrusion 4214 has a limiting effect to prevent the separation between the spring and the second end 4213 of the swing rod 421. At the same time, the positioning protrusion 4214 has a guiding effect on the elastic deformation displacement of the spring to prevent the spring from swaying and skewing when deforming.

[0064] In an exemplary embodiment, as Figure 7 and Figure 8 shown, an installation notch 1-2 is provided at one end of the first hinge seat 1 close to the second hinge seat 2; a protruding portion 22 inserted into the installation notch 1-2 is provided at one end of the second hinge seat 2 close to the first hinge seat 1, and the second hinge portion 21 is located on the protruding portion 22.

[0065] The first hinge portion 1-1 includes two support portions 1-11. Along the direction of the first rotation axis 3, the two support portions 1-11 are located on opposite sides of the installation notch 1-2.

[0066] As Figure 5 and Figure 6 shown, the hinge assembly 100 further includes a pin shaft 6. The pin shaft 6 passes through the second hinge portion 21, and both ends of the pin shaft 6 are respectively connected to the two support portions 1-11.

[0067] Specifically, an installation notch 1-2 is provided at one end of the first hinge seat 1 close to the second hinge seat 2, and the second hinge seat 2 is provided with a protruding portion 22 corresponding to the installation notch 1-2, so that the size of the hinge assembly 100 can be designed to be smaller, reducing the space occupied by the hinge assembly 100.

[0068] As Figure 7 shown, the second hinge portion 21 is provided with a hole extending along the axial direction of the second hinge portion 21. AsFigure 8 As shown, holes with an extending direction the same as that of the first rotation axis 3 are respectively provided on two support seats 1-11. When assembling the hinge assembly 100, the pin shaft 6 penetrates through the hole extending along its axial direction of the second hinge portion 21, and both ends of the pin shaft 6 are respectively inserted into the holes on the two support seats 1-11 with the same extending direction as that of the first rotation axis 3. In this way, the first hinge seat 1 can rotate relative to the second hinge seat 2 around the first rotation axis 3.

[0069] In an exemplary embodiment, as Figure 6 shown, the hinge assembly 100 further includes a gasket 61. The gasket 61 is sleeved outside the pin shaft 6, and the gasket 61 is located between the second hinge portion 21 and the support portion 1-11.

[0070] Specifically, during the rotation of the hinge assembly 100, the gasket 61 can reduce the wear and damage between the second hinge portion 21 and the support portion 1-11.

[0071] In an exemplary embodiment, as Figure 6 and Figure 10 shown, the hinge assembly 100 further includes: a pressing plate 7 and two pins 8. The pressing plate 7 is arranged on the side of the swing rod 421 facing away from the support portion 1-11.

[0072] As Figure 9 shown, both swing rods 421 are provided with shaft holes 4215. The two pins 8 respectively penetrate through the two shaft holes 4215. One end of each of the two pins 8 is respectively connected to the two support portions 1-11, and the other end of each of the two pins 8 is connected to the pressing plate 7.

[0073] Specifically, the pressing plate 7 has a limiting effect on the swing rod 421. The swing rod 421 is located between the pressing plate 7 and the support portion 1-11, and the pressing plate 7 can limit the movement of the swing rod 421 in the direction along the second rotation axis 5. During the rotation of the hinge assembly 100, the pressing plate 7 can prevent the swing rod 421 from shaking.

[0074] As Figure 6 shown, the pressing plate 7 is provided with a hole extending along the direction of the second rotation axis 5. As Figure 8 shown, the support portion 1-11 is provided with a hole extending along the direction of the second rotation axis 5. When assembling the hinge assembly 100, the pin 8 penetrates through the shaft hole 4215 of the swing rod 421, and both ends of the pin 8 are respectively inserted into the holes extending along the direction of the second rotation axis 5 of both the pressing plate 7 and the support portion 1-11, so that the swing rod 421 can be limited between the pressing plate 7 and the support portion 1-11.

[0075] In an exemplary embodiment, as Figure 8 and Figure 10As shown, the first hinge seat 1 further includes a limit rib 1-3, and the limit rib 1-3 extends from one support portion 1-11 to the other support portion 1-11; the limit rib 1-3 is higher than the support portion 1-11, and the pressure plate 7 is connected to the limit rib 1-3 through a fastener 9.

[0076] Specifically, the limit rib 1-3 has a limiting effect on the second hinge portion 21. The limit rib 1-3 can be used to install and fix the pressure plate 7. As Figure 6 and Figure 8 shown, holes extending along the direction of the second rotation axis 5 are provided on both the limit rib 1-3 and the pressure plate 7, and the fastener 9 passes through the above holes to fixedly connect the pressure plate 7 and the limit rib 1-3 together.

[0077] In an exemplary embodiment, as Figure 6 and Figure 12 shown, the hinge assembly 100 further includes a limit frame 10 fixed on the first hinge seat 1, the reset assembly 4 is located inside the limit frame 10, and the limit frame 10 includes a first limit wall 10-1.

[0078] The first limit wall 10-1 is in the same extending direction as the limit rib 1-3 and is spaced apart. The elastic member 422 is disposed between the first limit wall 10-1 and the limit rib 1-3.

[0079] Specifically, the limit frame 10 has a limiting effect on the reset assembly 4 to prevent the reset assembly 4 from deflecting and shaking during the rotation of the hinge assembly 100. When the hinge assembly 100 is in a humid environment, the limit frame 10 also has a waterproof function. The limit frame 10 can prevent water from entering the inside of the reset assembly 4 and the second hinge portion 21, and the limit frame 10 can prevent the hinge assembly 100 from being corroded by moisture.

[0080] The elastic member 422 is disposed between the first limit wall 10-1 and the limit rib 1-3. Both the first limit wall 10-1 and the limit rib 1-3 have a limiting and protecting effect on the elastic member 422, and can prevent the elastic member 422 from deflecting and shaking during elastic deformation.

[0081] In an exemplary embodiment, as Figures 3 to 6 shown, the hinge assembly 100 further includes a first back plate 11 and a second back plate 12. The first back plate 11 and the first hinge seat 1 are oppositely arranged and connected together through a first fastener 13, and the second back plate 12 and the second hinge seat 2 are oppositely arranged and connected together through a second fastener 14.

[0082] Specifically, when a door is installed on the side of the first hinge seat 1 facing the support portion 1-11, the first back plate 11 can be used to press and fix the door. At this time, the door is located between the first back plate 11 and the first hinge seat 1, and the first fastener 13 penetrates the door in the thickness direction of the door. When a door is installed on the side of the second hinge seat 2 facing the second hinge portion 21, the second back plate 12 can be used to press and fix the door. At this time, the door is located between the second hinge seat 2 and the second back plate 12, and the second fastener 14 penetrates the door in the thickness direction of the door.

[0083] In an exemplary embodiment, as Figure 4 and Figure 6 shown, the first hinge seat 1 is provided with a first protrusion 1-4 on the side facing the first back plate 11, the second hinge seat 2 is provided with a second protrusion 23 on the side facing the second back plate 12, the first protrusion 1-4 and the second protrusion 23 are both provided with threaded holes, the first fastener 13 passes through the first back plate 11 and is connected to the threaded hole of the first protrusion 1-4, and the second fastener 14 passes through the second back plate 12 and is connected to the threaded hole of the second protrusion 23.

[0084] Specifically, the first protrusion 1-4 can limit the relative distance between the first hinge seat 1 and the first back plate 11, and the second protrusion 23 can limit the relative distance between the second hinge seat 2 and the second back plate 12. Optionally, as Figure 7 and Figure 8 shown, the first hinge seat 1 is provided with two first protrusions 1-4 to make the connection between the first hinge seat 1 and the first back plate 11 more stable, and the second hinge seat 2 is provided with two second protrusions 23 to make the connection between the second hinge seat 2 and the second back plate 12 more stable.

[0085] In an exemplary embodiment, as Figure 4 and Figure 6As shown, the hinge assembly 100 further includes a plurality of expansion sleeves 15, and the plurality of expansion sleeves 15 are respectively sleeved outside the first protrusion 1-4 and the second protrusion 23. Specifically, the plurality of expansion sleeves 15 are respectively sleeved outside the first protrusion 1-4 and the second protrusion 23. The expansion sleeve 15 can be made of POM material. In this way, when the first protrusion 1-4 and the second protrusion 23 pass through the holes of the external structure, the connection between the first protrusion 1-4 and the second protrusion 23 and the external structure can be made tighter. For example, the external structure can be a door. One door is arranged between the first hinge seat 1 and the first back plate 11, and one door is arranged between the second hinge seat 2 and the second back plate 12. The first protrusion 1-4 is arranged to pass through the hole in the thickness direction of one door, and the second protrusion 23 is arranged to pass through the hole in the thickness direction of the other door. The expansion sleeve 12 can make the connection between the first protrusion 1-4 and the second protrusion 23 and the door tighter. In particular, when the hinge assembly 100 is applied to the glass door of a shower room, due to the relatively smooth and slippery characteristics of the glass, with the above structural design of the expansion sleeve 15, the glass door can be better fixed on the hinge assembly 100.

[0086] In an exemplary embodiment, as Figures 3 to 6 shown, the hinge assembly 100 further includes a first gasket 16 and a second gasket 17. At least one first gasket 16 is provided between the first back plate 11 and the first hinge seat 1, and at least one second gasket 17 is provided between the second back plate 12 and the second hinge seat 2.

[0087] Specifically, the first gasket 16 and the second gasket 17 can be made of high-density polyethylene (HDPE) material. The first gasket 16 can slow down the wear between the first back plate 11 and the first hinge seat 1 and the door, and prevent the first back plate 11 and the first hinge seat 1 from damaging the outer surface of the door. The second gasket 17 can slow down the wear between the second back plate 12 and the second hinge seat 2 and the door, and prevent the second back plate 12 and the second hinge seat 2 from damaging the outer surface of the door.

[0088] The plurality of first gaskets 16 and the plurality of second gaskets 17 can all be set to different thicknesses, so that the thickness of the door installed on the hinge assembly 100 can be adjusted.

[0089] In an exemplary embodiment, as Figure 6 shown, the first gasket 16 is provided with a notch 16-1 for avoiding the reset assembly 4 and the expansion sleeve 15.

[0090] Specifically, the notch 16-1 has the function of making way, preventing interference between structures such as the reset assembly 4 and the second hinge portion 21 and the first gasket 16.

[0091] The working principle of the hinge assembly 100 of the present application is as follows: The first hinge seat 1 can rotate relative to the second hinge seat 2 about the first rotation axis 3. As Figures 13 to 14 shown, when the hinge assembly 100 is in the fully open position, the two rolling bodies are respectively located on the two planes 212 at the axial ends of the second hinge portion 21, and the elastic member 422 is in a compressed state. When the hinge assembly 100 rotates from Figure 13 the fully open position shown in, to Figure 11 the partially open position shown in, the two rolling bodies respectively roll along the two planes 212 towards the direction close to the two reset grooves 211. At this time, the two rolling bodies are respectively located on the two planes 212 at the axial ends of the second hinge portion 21. When the hinge assembly 100 rotates from Figure 11 the partially open position shown in, to Figure 10 the closed position shown in, the two swing rods 421 make rotational movements driven by the elastic restoring force of the elastic member 422, so that the two rolling bodies respectively automatically roll into the two reset grooves 211, thereby realizing the small-angle automatic closing action of the hinge assembly 100. Moreover, restricted by the driving force of the elastic member 422 and the swing rod 421, it is difficult for the two rolling bodies to escape from their respective reset grooves 211, making the hinge assembly 100 of the present application close tightly and the closing reset accurate.

[0092] The embodiment of the present application provides a shower room, which includes a shower room main body, a door, and the hinge assembly 100 as described in any one of the above exemplary embodiments. The door is installed on the shower room main body and is connected to the hinge assembly 100.

Therefore, the shower room has the structural features and advantages of the hinge assembly 100 as described in any one of the above exemplary embodiments.

[0094] The hinge assembly 100 of the present application has the advantages of small-angle automatic closing and accurate closing reset. The shower door connected to the hinge assembly 100 also has the advantage of accurate closing reset. The door of this shower room can be closed tightly, and the sealing performance of the door of the shower room is good, which can prevent the water flow during shower spraying from flowing to the outside of the shower room.

[0095] In an exemplary embodiment, the door includes a first door and a second door. The first door is connected to the first hinge seat 1, and the second door is connected to the second hinge seat 2; the shower room is arranged such that when the second hinge seat 2 rotates relative to the first hinge seat 1 to the closed position, the first door and the second door are flush.

[0096] Specifically, the door of the shower room of the present application can be an outward-opening door. When the second hinge seat 2 and the first hinge seat 1 rotate relative to each other to Figure 10When in the closed position shown, the first door and the second door are flush, and at this time, the door of the shower room is in the closed position. When the second hinge seat 2 and the first hinge seat 1 rotate relative to each other to Figure 11 and Figure 13 the position shown, the second door or the first door is opened.
