[0009] A damping member, including a damper and a sliding part provided on the damper. The damper is spaced from the driving part in the first direction. The damper drives the sliding part to move along the first direction. When the first hinge rotates relative to the second hinge, the sliding part is used to provide a reaction force to the driving part abutting against the sliding part;

[0010] Wherein, among the two abutting surfaces of the driving part and the sliding part for mutual abutment, at least one is set as a driving inclined surface, and the driving inclined surface inclines away from the sliding part in a direction away from the first hinge.

[0011] Optionally, a driving inclined surface is provided on the driving part, the sliding part includes an abutting inclined surface configured to abut against the driving inclined surface, and the abutting inclined surface is adapted to the driving inclined surface.

[0015] Optionally, the second hinge forms a receiving groove, and the driving part and the sliding part are disposed in the receiving groove;

[0016] The receiving groove includes two first side walls and a second side wall. The two first side walls are spaced apart in the first direction and extend along the second direction, and the second side wall extends along the first direction and is disposed at one end of the two first side walls away from the first hinge;

[0017] Two end faces of the driving part in the first direction are abutted against the two first side walls;

[0018] One end face of the sliding part in the second direction and facing away from the first hinge is abutted against the side away from the second side wall.

[0019] Optionally, the second hinge includes:

[0020] A bottom plate, the bottom plate includes the receiving groove; and,

[0021] A cover plate, which is disposed at the notch of the receiving groove to enclose a sealed cavity with the bottom plate.

[0022] Optionally, the driving assembly further includes an elastic member, the elastic member is disposed between the driving part and the second hinge, and the elastic member is configured to provide an elastic driving force when the driving part moves towards the sliding part and provide a reverse acting force when the driving part moves away from the sliding part.

[0023] Optionally, one end face of the sliding part in the first direction and facing away from the driving part is concavely provided with a guiding groove extending along the first direction. The damper is sleeved in the guiding groove, and one end of the damper facing away from the sliding part is fixed to the second hinge.

When the door and window are closed, the first hinge rotates relative to the second hinge, and the linkage part drives the driving part to move along the second direction. When the driving part abuts against the sliding part, the force transmitted to the sliding part by the original force through the driving inclined surface forms an angle with both the second direction and the first direction. Therefore, the original force is decomposed into the force in the first direction as a component of the original force, and the value of the component force is less than the value of the original force. Therefore, the axial force acting on the damper is reduced, reducing the risk of damage to the damper, so as to solve the problem that the existing hinges are easily damaged when excessive force is applied when opening and closing doors and windows.

[0042] Modern households have increasingly high requirements for bathroom facilities. Shower rooms with a buffering function have become the focus of users' purchases. A buffering shower room can avoid the problem of strong collision and noise generation between the glass door and the shower room body. To prevent strong collision between the glass door and the shower room body when the glass door is closed, a damper is provided inside the hinge to slow down the force exerted by the glass door on the shower room body. When the glass door rotates, too large a force will directly act on the axial direction of the damper, and the damper is prone to damage.

[0043] To solve the above problems, the present invention provides a hinge assembly. Figures 1 to 7 This is a specific embodiment of the hinge assembly provided by the present invention.

[0044] Please refer to Figure 1 、 Figure 5 and Figure 7 As shown in, the hinge assembly includes a first hinge 1, a second hinge 2, a driving component, and a damping component. The second hinge 2 is rotatably connected to the first hinge 1 along an axis extending in a first direction. The driving component includes a linkage portion 3 and a driving portion 4. The linkage portion 3 has a first end and a second end disposed opposite to each other. The first end of the linkage portion 3 is movably connected to the first hinge 1, and the second end of the linkage portion 3 is provided with the driving portion 4. The driving portion 4 is movably mounted on the second hinge 2 in a second direction approaching and departing from the first hinge 1. The damping component includes a damper 5 and a sliding portion 6 provided on the damper 5. The damper 5 is spaced from the driving portion 4 in the first direction. The damper 5 drives the sliding portion 6 to move along the first direction. When the first hinge 1 rotates relative to the second hinge 2, the sliding portion 6 is used to provide a reaction force to the driving portion 4 that abuts against the sliding portion 6. Among them, at least one of the two abutting surfaces for the driving portion 4 and the sliding portion 6 to abut against each other is provided as a driving inclined surface 41, and the driving inclined surface 41 inclines in a direction away from the sliding portion 6 in a direction away from the first hinge 1.

[0045] In the technical solution provided by the present invention, one of the first hinge 1 and the second hinge 2 is connected to the door or window, and the other is connected to the room body. When closing the door or window, the first hinge 1 rotates relative to the second hinge 2, and the linkage portion 3 drives the driving portion 4 to move along the second direction. When the driving portion 4 abuts against the sliding portion 6, since the force transmitted from the original acting force to the sliding portion 6 through the driving inclined surface 41 forms an angle with both the second direction and the first direction, the force decomposed to the first direction from the original acting force is a component force of the original acting force, and the value of the component force is smaller than the value of the original acting force. Therefore, the force acting on the axial direction of the damper 5 is reduced, and the risk of damage to the damper 5 is reduced, so as to solve the problem that the existing hinge is prone to damage when the door or window is opened or closed with excessive force.

[0046] It should be noted that since the damper 5 only needs to provide a reaction force with the same magnitude as the value of the component force to buffer the doors and windows, therefore, only a damper 5 with a relatively small damping value needs to be set to meet the requirements, and the selection range of the damping value of the damper 5 is wider.

[0047] It can be understood that in the prior art, generally, the direction of the movement stroke of the sliding part 6 of the damping member is parallel to the direction of the movement stroke of the driving part 4, that is, the sliding part 6 is arranged at one end of the driving part 4. Therefore, in order to provide a reaction resistance to the driving part 4, the movement stroke of the sliding part 6 matches the movement stroke of the driving part 4. Inevitably, the length of the hinge setting will be relatively long and the volume will be relatively large. As a result, the sizes of the related components will increase accordingly, leading to an increase in the production cost. Moreover, for some specific small-sized door and window structures, the application range of this kind of hinge is limited.

[0048] In the present invention, the damper 5 is arranged on the side of the linkage part 3 and the driving part 4. When the hinge assembly is opened and closed, when the driving part 4 moves the same buffering stroke, the movement stroke of the sliding part 6 is significantly smaller. Therefore, the size of the damping member is also smaller, and the overall volume of the hinge assembly will also be reduced accordingly, and the production cost will be reduced.

[0049] Furthermore, in a specific embodiment, the driving slope 41 is arranged on the driving part 4, and the sliding part 6 includes an abutting slope 61 for abutting against the driving slope 41. The abutting slope 61 is adapted to the driving slope 41. In this way, the abutting area of the two slopes is relatively large, avoiding excessive pressure on the driving slope 41. When the doors and windows are actually opened and closed relatively frequently, the driving slope 41 is easily worn.

[0050] It can be understood that, referring to Figure 7 , according to the decomposition of forces, the magnitude of the angle of the driving slope 41 directly affects the magnitude of the component force acting on the sliding part 6. Therefore, different slopes of the slope can be made according to the environmental requirements. Under the action of the component force and the damping member, the overall buffering effect is more linear.

[0051] Therefore, further, the driving part 4 is detachably connected to the linkage part 3; and / or, the sliding part 6 is detachably connected to the damper 5. In this way, in actual production, when the damping value of the sliding part 6 is different, that is, the matched damper 5 is different, the slope of the driving slope 41 can be set to different specifications and models. The driving part 4 and the sliding part 6 are separately produced and processed, and then assembled according to actual needs, improving the versatility of the hinge assembly.

[0052] Furthermore, referring toFigure 7 , the driving inclined surface 41 is inclined in the third direction, and an acute angle formed between the third direction and the second direction is θ. The acting force of the driving inclined surface 41 on the abutting inclined surface 61 is F2, and the direction of F2 is perpendicular to the third direction. Through the decomposition of forces, it can be known that the component force of F2 in the second direction is F3, and the component force in the first direction is F4. The angle between F4 and F2 is θ. Thus, when the value of F2 is constant, the magnitude of F4 depends on the magnitude of θ. The larger θ is, the smaller the value of F4 is, and the damping value of the damper 5 can be appropriately selected to be smaller. On the contrary, the smaller θ is, the larger the damping value of the damper 5 needs to be set. In a specific embodiment, 45° ≤ θ ≤ 75°. Preferably, θ = 60°. Within this angle range, the matching stroke of the damping member and the damper 5 can achieve the best balance.

[0053] Furthermore, in this embodiment, the second hinge 2 forms a receiving groove 2a, and the driving part 4 and the sliding part 6 are arranged in the receiving groove 2a; the receiving groove 2a includes two first side walls 21 and a second side wall 22. The two first side walls 21 are spaced apart in the first direction and extend along the second direction. The second side wall 22 extends along the first direction and is arranged at one end of the two first side walls 21 away from the first hinge 1; the two end faces of the driving part 4 in the first direction are abutted against the two first side walls 21; one end face of the sliding part 6 in the second direction and facing away from the first hinge 1 is abutted against and away from the second side wall 22. With such a setting, the side walls of the receiving groove 2a can play a guiding role. When the driving part 4 moves along the second direction, it can be limited between the two first side walls 21. When the sliding part 6 moves along the first direction, the second side wall 22 can provide a certain reaction force for the sliding part 6 to prevent the sliding part 6 from swinging along the second direction.

[0054] Furthermore, in order to facilitate the cleaning of the hinge assembly, dirt is not easily introduced into the mating parts of the moving components in the hinge assembly, avoiding problems such as abnormal noise and inflexibility when the hinge is opened and closed. Therefore, please refer to Figure 1 , in this embodiment, the second hinge 2 includes a bottom plate 23 and a cover plate 24. The bottom plate 23 includes the receiving groove 2a, and the cover plate 24 covers the opening of the receiving groove 2a to enclose a sealed cavity with the bottom plate 23. It can be understood that in the hinge assembly, except for the driving part 4 and the sliding part 6, other moving parts are also arranged in the receiving groove 2a.

[0055] Further, in order to provide a certain damping feeling when the door and window structure is opened, in this embodiment, the driving assembly further includes an elastic member 7. The elastic member 7 is disposed between the driving portion 4 and the second hinge 2. The elastic member 7 is used to provide an elastic driving force when the driving portion 4 moves toward the sliding portion 6, and provide a reverse acting force when the driving portion 4 moves away from the sliding portion 6. Thus, when the door and window is opened and the first hinge 1 rotates relative to the second hinge 2 at an angle of about 90°, the linkage portion 3 is driven to move toward the first hinge 1. At this time, the elastic member 7 is in a state of being gradually compressed. Therefore, when opening the door and window structure, it is necessary to overcome the reaction force generated by the deformation of the elastic member 7, so that when the user uses it, a better damping effect can be obtained.

[0056] More specifically, please refer to Figure 5 and Figure 6 . In a specific embodiment, there are two elastic members 7. The two elastic members 7 are spaced apart in the first direction and are respectively disposed on both sides of the linkage portion 3. Thus, the two elastic members 7 can provide a greater reaction force and make the linkage portion 3 move more smoothly along the second direction.

[0057] Specifically, please refer to Figure 6 . In an embodiment, a guide groove 6a extending in the first direction is recessed in an end face of the sliding portion 6 in the first direction and facing away from the driving portion 4. The damper 5 is sleeved in the guide groove 6a, and one end of the damper 5 facing away from the sliding portion 6 is fixed to the second hinge 2. When the sliding portion 6 moves relative to the damper 5 in the first direction, the guide groove 6a is used to guide the damper 5. Thus, when the damper 5 works and moves in the first direction, the swinging of the damper 5 and the sliding portion 6 is avoided, ensuring the stability of the fitting between the driving inclined surface 41 and the abutting inclined surface 61.

[0058] Specifically, please refer to Figure 1 and Figure 3, in a specific embodiment, the first hinge 1 is provided with a first jack 1a along the first direction, and the driving part 4 is provided with a second jack 4a along the first direction; a first connection hole 3a is provided at the first end of the linkage part 3, and a second connection hole 3b is provided at the second end of the linkage part 3. The linkage part 3 is rotatably connected to the first hinge 1 through a first rotating shaft 8 passing through the first jack 1a and the first connection hole 3a, and the linkage part 3 is rotatably connected to the driving part 4 through a second rotating shaft 9 passing through the second jack 4a and the second connection hole 3b. Thus, when the first hinge 1 is rotatably connected to the second hinge 2 through a third rotating shaft, an installation hole for the third rotating shaft is provided on the first hinge 1. Since it is spaced from the first jack 1a, when the first hinge 1 and the second hinge 2 rotate relative to each other, the first jack 1a rotates around the installation hole. Therefore, it can drive the rotation of the first end of the linkage part 3. In the second direction, the second end of the linkage part 3 has a moving stroke along the second direction, thereby driving the driving part 4 to move along the second direction.

[0059] The present invention also provides a door and window structure, and the door and window structure includes the above hinge assembly. Since the door and window structure includes the hinge assembly, the specific structure of the hinge assembly refers to the above embodiments. Since the hinge assembly of this door and window structure adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

[0060] Specifically, a first installation part is provided on the first hinge 1, and the first installation part is connected to the door body or the window body. A second installation part is provided on the second hinge 2, and the second installation part is used to be connected to the building body.

[0061] More specifically, the first installation part is set as a first threaded hole, and the second installation part is set as a second threaded hole. Thus, it can be screwed with the first threaded hole or the second threaded hole through a bolt.

[0062] The present invention also provides a shower room, and the shower room includes the above door and window structure. Since the shower room includes the door and window structure, the specific structure of the door and window structure refers to the above embodiments.
