The requirements of modern households on bathroom facilities are higher and higher, and a shower room with a buffer function becomes a user buying important point, so that the buffer shower room can avoid the problems of strong collision between a glass door and a shower room body and noise manufacturing. In order to avoid strong collision between the glass door and the shower room body when the glass door is closed, a damper is arranged in the hinge to slow down the force of the glass door on the shower room body, and the damper is easy to damage due to the fact that the excessive acting force can directly act on the axial direction of the damper when the glass door rotates.

In order to solve the above-mentioned problems, the present utility model provides a hinge assembly, and fig. 1 to 7 are specific embodiments of the hinge assembly provided by the present utility model.

Referring to fig. 1, 5 and 7, the hinge assembly includes a first hinge 1, a second hinge 2, a driving assembly and a damping member, where the second hinge 2 is rotatably connected to the first hinge 1 along an axis extending in a first direction; the driving assembly comprises a linkage part 3 and a driving part 4, wherein the linkage part 3 is provided with a first end and a second end which are oppositely arranged, the first end of the linkage part 3 is movably connected with the first hinge 1, the second end of the linkage part 3 is provided with the driving part 4, and the driving part 4 is movably arranged on the second hinge 2 in a second direction close to and far from the first hinge 1; the damping piece comprises a damper 5 and a sliding part 6 arranged on the damper 5, wherein the damper 5 and the driving part 4 are arranged at intervals in the first direction, the damper 5 drives the sliding part 6 to move along the first direction, and the sliding part 6 is used for providing a reaction force for the driving part 4 abutted against the sliding part 6 when the first hinge 1 rotates relative to the second hinge 2; wherein at least one of the two abutting surfaces of the driving portion 4 and the sliding portion 6 for abutting against each other is provided as a driving inclined surface 41, and the driving inclined surface 41 is inclined in a direction away from the sliding portion 6 in a direction away from the first hinge 1.

In the technical scheme provided by the utility model, one of the first hinge 1 and the second hinge 2 is connected with a door and a window, the other is connected with a house body, when a door and a window are closed, the first hinge 1 rotates relative to the second hinge 2, the linkage part 3 drives the driving part 4 to move along the second direction, when the driving part 4 abuts against the sliding part 6, an included angle is formed between the force transmitted to the sliding part 6 by the original acting force through the driving inclined surface 41 and the second direction and the first direction, so that the force of the original acting force decomposed to the first direction is a component of the original acting force, the value of the component is smaller than the value of the original acting force, and therefore, the force acting on the damper 5 in the axial direction is reduced, the damage risk of the damper 5 is reduced, and the problem that the hinge is easy to damage when the door and the window are excessively opened and closed is solved.

It should be noted that, since the damper 5 only needs to provide a reaction force with the magnitude consistent with the magnitude of the component force to buffer the door and the window, the requirement can be satisfied by only setting the damper 5 with a smaller damping value, and the selection range of the damping value of the damper 5 is wider.

It will be appreciated that in the prior art, the direction of the movable stroke of the sliding portion 6 of the damping member is generally parallel to the direction of the movable stroke of the driving portion 4, that is, the sliding portion 6 is disposed at one end of the driving portion 4, so that the movable stroke of the sliding portion 6 is matched with the movable stroke of the driving portion 4 in order to provide a reaction resistance to the driving portion 4, so that the hinge is inevitably longer in length and larger in size, so that the associated parts are correspondingly increased in size, resulting in increased production cost, and the hinge has limited application range for some door and window structures with specific small sizes.

In the present utility model, the damper 5 is disposed at the side of the linkage part 3 and the driving part 4, and when the hinge assembly is opened and closed, the movable stroke of the sliding part 6 is significantly smaller when the driving part 4 moves by the same buffer stroke, so that the size of the damper is smaller, the whole volume of the hinge assembly is correspondingly reduced, and the production cost is also reduced.

Further, in a specific embodiment, the driving inclined surface 41 is disposed on the driving portion 4, the sliding portion 6 includes an abutting inclined surface 61 for abutting against the driving inclined surface 41, and the abutting inclined surface 61 is adapted to the driving inclined surface 41, so that the abutting area of the two inclined surfaces is larger, and the driving inclined surface 41 is prevented from being worn easily when the door and window are opened and closed frequently due to excessive pressure on the driving inclined surface 41.

It will be appreciated that referring to fig. 7, as can be seen from the force decomposition, the magnitude of the angle of the driving ramp 41 directly affects the magnitude of the component force acting on the sliding portion 6, so that different ramp gradients can be made according to the environment requirement, and the overall buffering effect is more linear under the action of the component force and the damping member.

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. Thus, in actual production, when the damping values of the sliding parts 6 are different, that is, the matched dampers 5 are different, the gradient of the driving inclined plane 41 can be set to different specifications and models, the driving parts 4 and the sliding parts 6 are independently produced and processed, and then the assembly is selected according to actual requirements, so that the universality of the hinge assembly is improved.

Further, referring to fig. 7, the driving inclined surface 41 is inclined along a third direction, 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, the direction of F2 is perpendicular to the third direction, the force component of F2 along the second direction is F3 as a result of force decomposition, the force component along the first direction is F4, and the angle between F4 and F2 is θ, so that when the F2 value is fixed, the magnitude of F4 depends on the magnitude of θ, the larger θ, the smaller the value of F4, the smaller the damping value of the damper 5 can be properly selected, whereas the smaller θ, the larger the damping value of the damper 5 needs to be set, and in a specific embodiment, the magnitude of θ is 45 ° and θ is less than or equal to 75 °. Preferably, θ=60°. Within this angular range, the matching of the damper 5 and the adapting stroke of the damping element can be optimally balanced.

So set up, the lateral wall of holding tank 2a can play the guide effect, when drive portion 4 is along the activity of second direction can be limited in between two first lateral walls 21, when slider 6 is along the activity of first direction, second lateral wall 22 can be for slider 6 provides certain reaction force, avoids slider 6 is along the swing of second direction.

Further, in order to facilitate cleaning of the hinge assembly, dirt is not easy to enter into the mutually matched parts of the movable parts in the hinge assembly, and problems of abnormal sound, unsmooth and the like of the hinge during opening and closing are avoided, so referring to fig. 1, in this embodiment, the second hinge 2 includes a bottom plate 23 and a cover plate 24, the bottom plate 23 includes the accommodating groove 2a, and the cover plate 24 covers the notch of the accommodating groove 2a so as to enclose with the bottom plate 23 to form a sealed cavity. It will be appreciated that in the hinge assembly, other movable parts are also provided in the receiving groove 2a, in addition to the driving portion 4 and the sliding portion 6.
