Description

TECHNICAL FIELD

[0001] The present application relates to the field of hardware accessories, and particularly to a door moving device with an anti-sway function.BACKGROUND

[0002] During the use of a door body, there is a movement process relative to a fixed structure mounting the door body, so that the door body moves in an opening direction or in a closing direction. Various devices are used for moving door bodies of different types of furniture.

[0003] In the related art, there is a movement mechanism for an upwardly tilting door, suitable for being arranged on a side of a piece of furniture or inside the side. The mechanism is accommodated in a box body composed of two half-shells and includes a hinge with five points, the hinge consisting of three links. The links are hinged to each other at a fulcrum, the fulcrum being arranged in one of the middle regions of these links. An end of one of the links is hinged to an end of another link at the fulcrum. An opposite end of the link is hinged to the door at a point. An end of another link is hinged to the door at a point, while an opposite end of the link carries a pin sliding in a track formed in the box body. The link is also hinged to the box body at the fulcrum. During the movement of the door body, the links rotate about the fulcrum, where a link acts directly or indirectly on a cam profile of a linear slider. The linear slider is subjected to the direct action of an elastic device, thereby generating a force tending to open the mechanism and thus supporting the weight of the door body.

[0004] In the technical solution of the aforementioned movement mechanism for the upwardly tilting door where the link directly or indirectly acts on the cam profile of the linear slider:

[0005] In the technical solution where the link indirectly acts on the cam profile of the linear slider, there are five connection points between the hinge and the box body, namely, a fulcrum, a rotation center, a sliding connection point formed by a pin sliding in a second groove, a sliding connection point formed by a pin sliding in a track, and a sliding connection point formed by a roller sliding on the cam profile of the linear slider. The combined connection method of two rotational connection points and three sliding connection points results in strong overall stability of the structure, but requires coordination between the hinge, a push rod, and links. Cooperation is needed between the push rod and the box body, between the push rod and the link, and between the links, leading to a relatively complex overall structure, which increases assembly difficulty and production costs.

[0006] In the technical solution where the link directly acts on the cam profile of the linear slider, there are only three connection points between the hinge and the box body, namely, a fulcrum, a sliding connection point formed by a pin sliding in a track, and a sliding connection point formed by a roller sliding on the cam profile of the linear slider. Among the three connection points, two are sliding connection points and one is a rotational connection point. During the movement of the hinge, since both connection points between it and the box body are sliding connection points, and these two sliding connection points both lack limitation in a direction perpendicular to the mounting surface of the upwardly tilting door movement mechanism, when the size of the door connected to this upwardly tilting door movement mechanism is large, a certain degree of sway occurs in the direction perpendicular to the mounting surface of the upwardly tilting door movement mechanism. This affects the operational stability of the upwardly tilting door movement mechanism, and further affects the accuracy of the door connected to this mechanism at the closed position, leading to issues such as interference between the door and the box body.SUMMARY

[0007] In order to overcome at least one defect described in the above prior art, the present application provides a door movement device with an anti-sway function. The first connection point, the second connection point, and the third connection point form a relatively stable three-point connection method with the cabinet body, which may carry a door body with a larger mass.

It is only intended to facilitate description of the present application and simplify description, but not to indicate or imply that the referred device or element has a specific orientation, or is constructed and operated in a specific orientation. Therefore, they should not be construed as a limitation of the present application.

[0023] Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are used only to describe specific embodiments and are not intended as a limitation of the application.

[0024] Referring to FIGS. 1-8, the present application discloses a door movement device with an anti-sway function, including: a mounting base 10 configured to be mounted on a cabinet body 20; a slider 30 slidably connected to the mounting base 10, the slider 30 having a curved track 40; an elastic mechanism 50, an elastic force of the elastic mechanism 50 acting on the slider 30; a hinge mechanism 60, the hinge mechanism 60 including a first link 601, a second link 602, a third link 603, and a fourth link 604, a first end of the first link 601 being pivotally connected to the mounting base 10 to define a first connection point, a first end of the second link 602 being pivotally connected to the mounting base 10 to define a second connection point, a second end of the second link 602 being provided with a roller 605, the roller 605 moving along the curved track 40 to define a third connection point, a first end of the third link 603 being configured to be pivotally connected to a door body 70 to define a fourth connection point, a first end of the fourth link 604 being configured to be pivotally connected to the door body 70 to define a fifth connection point.

[0025] Based on the above structure, in the present application, the first end of the first link 601 is pivotally connected to the mounting base 10 to define the first connection point, the first end of the second link 602 is pivotally connected to the mounting base 10 to define the second connection point, and the roller 605 moves along the curved track 40 to define the third connection point; the first connection point, the second connection point, and the third connection point are rotational connection points, and the third connection point is a sliding connection point. When the present application is used, the first connection point, the second connection point, and the third connection point form a relatively stable three-point connection method with the cabinet body 20, ensuring the operational stability and accuracy of the hinge mechanism 60, and thereby enabling it to carry the door body 70 with a larger mass. The aforementioned stable three-point connection method may prevent swaying during the opening and closing process of the hinge mechanism 60 and the door body 70, and avoid interference between the door body 70 and the cabinet body 20. When the roller 605 moves to different curvature positions within a certain angle range of the curved track 40, the door body 70 may achieve hovering with the support of the elastic mechanism 50.

[0026] It should be noted that the elastic force of the elastic mechanism 50 acts on the door body 70 through the slider 30, the roller 605, and the hinge mechanism 60, thereby providing a supporting force to the door body 70, so that the door body 70 may achieve hovering. The aforementioned hovering refers to the state where, after the door body 70 is connected to the cabinet body 20 via the hinge mechanism 60, the door body 70 is opened relative to the cabinet body 20 and stops at a certain opening angle.

[0027] Since the first end of the third link 603 is configured to be pivotally connected to the door body 70 to form the fourth connection point, and the first end of the fourth link 604 is configured to be pivotally connected to the door body 70 to form the fifth connection point, the hinge mechanism 60 is pivotally connected to the door body 70 through the fifth connection point and the sixth connection point.

[0028] When the lines connecting the first connection point, the second connection point, and the third connection point are not collinear, a relatively stable triangular connection is formed between the first connection point, the second connection point, the third connection point, and the cabinet body 20.

[0029] In the embodiment of the present application, the second end of the first link 601 is pivotally connected to the middle portion of the fourth link 604, the middle portion of the second link 602 is pivotally connected to the second end of the fourth link 604, and the third end of the second link 602 is pivotally connected to the second end of the third link 603.

[0030] Furthermore, during the process of opening or closing the hinge mechanism 60, the first link 601 and the second link 602 always remain parallel or substantially parallel to each other, and the third link 603 and the fourth link 604 always remain parallel or substantially parallel to each other. Compared to a cross-link hinge mechanism formed by three links, the hinge mechanism 60 of the present application has better stability, more uniform force distribution, and a smoother opening or closing process, avoiding jamming.

[0031] In the embodiment of the present application, the second link 602 is pivotally connected to the roller 605, and the second link 602 and the slider 30 are nested with each other; so that during the movement of the roller 605 along the curved track 40, the outer contour of the roller 605 abuts against the outer contour of the curved track 40, and at least one side portion of the second link 602 limits the slider 30 in a direction perpendicular to the mounting surface of the mounting base 10.

[0032] In the embodiment of the present application, the two sides of the second link 602 extend outward to be provided with limiting side plates 606 at two sides of the roller 605, a limiting slot 607 is formed between the two limiting side plates 606, and the slider 30 is embedded in the limiting slot 607, referring to FIG. 4.

[0033] Alternatively, in other embodiments, the two sides of the slider 30 extend outward to be provided with limiting side plates 606, a limiting slot 607 is formed between the two limiting side plates 606, and the roller 605 is embedded in the limiting slot 607.

[0034] Furthermore, a buffer element 608 is provided on the limiting side plate 606. For example, the buffer element 608 may be a silicone pad, a rubber pad, etc., to reduce the impact force between the second link 602 and the slider 30.

[0035] Taking the mounting base 10 installed on the inner cavity side of the cabinet body 20 as an example for description, referring to FIG. 3, the direction perpendicular to the mounting surface of the mounting base 10 is the X-direction. The slider 30 is used to limit the second link 602 in the X-direction, thereby further improving the operational stability of the hinge mechanism 60 and further avoiding the sway thereof.

[0036] To achieve relative movement between the roller 605 and the slider 30 and to allow the slider 30 to limit the second link 602 in the X-direction, an installation gap is provided between the slider 30 and the limiting slot 607 or between the second link 602 and the limiting slot 607. This installation gap is as small as possible while ensuring that relative movement between the roller 605 and the slider 30 may be achieved. For example, the installation gap is a, where a is 1 mm to 2 mm.

[0037] During installation, an installation recess may also be provided on the inner cavity side of the cabinet body 20, and the mounting base 10 is installed in this installation recess, thereby avoiding occupying the internal space of the cabinet body 20 and achieving hidden installation.

[0038] Furthermore, the door movement device with an anti-sway function further includes a first pin shaft 609, a second pin shaft 610, a third pin shaft 611, a fourth pin shaft 612, a fifth pin shaft 613, a sixth pin shaft 614, a seventh pin shaft 615, and an eighth pin shaft 616.

[0039] The first end of the first link 601 is pivotally connected to the mounting base 10 via the first pin shaft 609 to define the first connection point. The first end of the second link 602 is pivotally connected to the mounting base 10 via the second pin shaft 610 to define the second connection point. The second end of the second link 602 is provided with the roller 605, and the second end of the second link 602 is pivotally connected to the roller 605 via the third pin shaft 611. The first end of the third link 603 is pivotally connected to the door body 70 via the fourth pin shaft 612 to define the fourth connection point. The first end of the fourth link 604 is pivotally connected to the door body 70 via the fifth pin shaft 613 to define the fifth connection point. The second end of the first link 601 is pivotally connected to the middle portion of the fourth link 604 via the sixth pin shaft 614. The middle portion of the second link 602 is pivotally connected to the second end of the fourth link 604 via the seventh pin shaft 615. The third end of the second link 602 is pivotally connected to the second end of the third link 603 via the eighth pin shaft 616.

[0040] In the embodiment of the present application, the mounting base 10 includes a backplate 101 and a panel 102. A side of the second link 602 facing the backplate 101 and a side of the second link 602 facing the panel 102 are both provided with support protrusions 617.

[0041] Specifically, the backplate 101 and the panel 102 are fastened together to form the mounting base 10. The hinge mechanism 60 and the elastic mechanism 50 are concealed and disposed within the space between the backplate 101 and the panel 102, thereby protecting the hinge mechanism 60 and the elastic mechanism 50.

[0042] The support protrusions 617 are used to reduce the gap between the second link 602 and the backplate 101 as well as the panel 102, minimizing sway of the hinge mechanism 60 in the X-direction during operation. Compared to a solution of increasing the overall thickness of the second link 602, using the support protrusions 617 may reduce costs and facilitate the assembly of the second link 602 into the mounting base 10.

[0043] In the embodiment of the present application, the curved track 40 includes at least two arc-shaped track segments, and the two arc-shaped track segments smoothly transition between each other.

[0044] It should be noted that the actual trajectory of the arc-shaped track segments corresponds to the operating trajectory of the hinge mechanism 60 and the opening angle of the door body 70. Since the elastic mechanism 50 drives the slider 30 to press against the roller 605, during the process of opening or closing the door body 70, the outer contour of the roller 605 abuts against the outer contour of the curved track 40, and the tangent point between the roller 605 and the curved track 40 changes as the hinge mechanism 60 operates. That is, the roller 605 moves at different curvature positions of the curved track 40. Therefore, depending on the actual application scenario, the curved track 40 may include two arc-shaped track segments, three arc-shaped track segments, four arc-shaped track segments, etc., which is not limited herein.

[0045] In the embodiment of the present application, the door movement device with an anti-sway function further includes a modular damper 80, the modular damper 80 being detachably connected to the mounting base 10; the hinge mechanism 60 is located beside the elastic mechanism 50, the modular damper 80 is located below the elastic mechanism 50; and the second link 602 acts on the modular damper 80 when the hinge mechanism 60 is closed.

[0046] It should be noted that the modular damper 80 may directly adopt an existing damper, and the damper is integrated on a base to form the modular damper 80; the modular damper 80 is detachably connected to the mounting base 10 via screws, and replacement of the modular damper 80 is achieved by installing or removing the screws to suit different application scenarios.

[0047] When the door body 70 is closed, the hinge mechanism 60 is also closed, and the second link 602 acts on the modular damper 80, thereby achieving slow closing of the door body 70, avoiding impact of the door body 70 on the cabinet body 20 when closing, and achieving damped door closing.

[0048] In the embodiment of the present application, the elastic mechanism 50 includes an elastic element 501, an elastic adjustment block 502, and an adjustment screw 503, one end of the elastic element 501 is connected to the elastic adjustment block 502, another end of the elastic element 501 is connected to the slider 30, the elastic adjustment block 502 is sleeved on the adjustment screw 503, and the elastic adjustment block 502 is threadedly connected to the adjustment screw 503; a first slide rail 103 and a second slide rail 104 are provided on the mounting base 10, the slider 30 is slidably connected to the first slide rail 103, and the elastic adjustment block 502 is slidably connected to the second slide rail 104; the adjustment screw 503 is rotated to drive the elastic adjustment block 502 to move closer to or away from the slider 30, thereby changing a compression amount of the elastic element 501.

[0049] When the door body 70 and the cabinet body 20 are closed, the hinge mechanism 60 is closed, pushing the slider 30 towards the elastic adjustment block 502, thereby compressing the elastic element 501. When the door body 70 and the cabinet body 20 are opened, the hinge mechanism 60 opens, pushing the slider 30 away from the elastic adjustment block 502, thereby resetting the elastic element 501. The elastic element 501 provides a supporting force to the door body 70 through the hinge mechanism 60, allowing the door body 70 to stop at a certain opening angle and preventing it from directly returning to the closed position due to the influence of its own gravity. The magnitude of the elastic force of the elastic element 501 corresponds to the gravity of the door body 70, with the criterion being able to support the door body 70. The magnitude of the elastic force of the elastic element 501 may be selected according to the actual application scenario.

[0050] In the embodiment of the present application, the elastic mechanism 50 further includes an adjustment seat 504 and an adjustment gear 505, the adjustment gear 505 being rotatably connected to the adjustment seat 504. A first adjustment tooth 506 is provided on the adjustment gear 505, a second adjustment tooth 507 is provided at an end portion of the adjustment screw 503, the first adjustment tooth 506 meshes with the second adjustment tooth 507, and the adjustment gear 505 is arranged perpendicular to the adjustment screw 503. The adjustment gear 505 is rotated to drive the adjustment screw 503 to rotate.

[0051] Specifically, the first slide rail 103, the second slide rail 104, and the adjustment seat 504 are all fixedly connected to the mounting base 10. The first slide rail 103, the second slide rail 104, and the adjustment seat 504 may all be fixedly connected to the mounting base 10 by means of screw connection or welding. The specific method of fixed connection depends on the actual situation and is not limited. The adjustment seat 504 is disposed between the slider 30 and the elastic adjustment block 502, and the specific installation position of the adjustment seat 504 is such that it does not interfere with the movement of the slider 30 and the elastic adjustment block 502.

[0052] Specifically, the elastic element 501 is a straight tube spring or elastic silicone. To achieve directional extension and contraction of the elastic element 501, both the slider 30 and the elastic adjustment block 502 are provided with guide columns 508. The elastic element 501 is sleeved outside the guide columns 508, and the guide columns 508 guide the extension and contraction of the elastic element 501.

[0053] The specific adjustment process for the compression amount of the elastic element 501 is as follows: The adjustment gear 505 is rotated in a forward direction to drive the adjustment screw 503 to rotate forward, thereby driving the elastic adjustment block 502 away from the slider 30, leading to a reduction in the compression amount of the elastic element 501. If the elastic element 501 needs to be replaced, it may be rotated forward until the elastic adjustment block 502 completely disengages from the adjustment screw 503, allowing for the replacement of the elastic element 501. The adjustment gear 505 is rotated in a reverse direction to drive the adjustment screw 503 to rotate in reverse, thereby driving the elastic adjustment block 502 closer to the slider 30, leading to an increase in the compression amount of the elastic element 501.

[0054] When the elastic element 501 is replaceable, an end of the elastic element 501 abuts the slider 30, and an opposite end of the elastic element 501 abuts the elastic adjustment block 502.

[0055] The aforementioned forward rotation refers to clockwise rotation, and the reverse rotation refers to counterclockwise rotation; or, the aforementioned forward rotation refers to counterclockwise rotation, and the reverse rotation refers to clockwise rotation; the selection is made according to the actual application scenario and is not limited herein.

[0056] In the embodiment of the present application, the door movement device with an anti-sway function further includes a position adjuster 90. The position adjuster 90 includes a locking screw (not shown in the drawings), a position fixing seat 901, and a position adjustment seat 902. The position fixing seat 901 is configured to be fixedly connected to the door body 70. The first end of the third link 603 and the first end of the fourth link 604 are both pivotally connected to the position adjustment seat 902. An adjustment slot 903 is provided on the position adjustment seat 902. The locking screw passes through the adjustment slot 903 and is fixedly connected to the position fixing seat 901.
