Description

A door moving device with anti-shake function Technical Field

[0001] This application relates to the field of hardware accessories, and more particularly to a door moving device with anti-shake function. Background Technology

[0002] During use, the door body moves relative to the fixed structure on which it is installed, allowing the door to move in the opening direction or in the closing direction. There are various devices used to move doors of different types of furniture.

[0003] In the related art, there is a sliding mechanism for an upward-tilting door, suitable for arrangement on or inside the side of furniture. The mechanism is housed in a box consisting of two half-shells and includes a five-point hinge composed of three rods hinged together at a fulcrum located in one of the middle regions of the rods. One end of each rod is hinged to the door at the fulcrum, and the other end is hinged to the door at the fulcrum. The other end of the rod has a pin that slides in a track formed in the box, also hinged to the box at the fulcrum. During door movement, the rods rotate about the fulcrum, wherein the rods act directly or indirectly on the cam profile of a linear slider subjected to the direct action of an elastic device, thereby generating a force that tends to open the mechanism and thus support the weight of the door.

[0004] The aforementioned upward-tilting door's moving mechanism employs a technical solution where a rod acts directly or indirectly on the cam profile of a linear slider.

[0005] In the technical solution where the rod indirectly acts on the cam profile of the linear slider, there are five connection points between the hinge and the housing: the fulcrum, the center of rotation, the sliding connection point formed by the pin sliding in the second groove, the sliding connection point formed by the pin sliding in the track, and the sliding connection point formed by the roller sliding on the cam profile of the linear slider. The combination of two rotational connection points and three sliding connection points results in strong overall stability of the structure. However, it requires the hinge to cooperate with the push rod and the rod. The push rod and the housing, the push rod and the rod, and the rod and the rod all need to cooperate, which makes the overall structure more complex and increases the difficulty of assembly and production cost.

[0006] In the technical solution where the rod directly acts on the cam profile of the linear slider, there are only three connection points between the hinge and the housing: a fulcrum, a sliding connection point formed by the pin sliding in the track, and a sliding connection point formed by the roller sliding on the cam profile of the linear slider. Two of these connection points are sliding connection points, and one is a rotational connection point. During the hinge's movement, since both connection points between it and the housing are sliding connection points, and these two sliding connection points lack limiting in the direction perpendicular to the mounting surface of the upward tilting door's moving mechanism, when the size of the door connected to the upward tilting door's moving mechanism is large, a certain degree of swaying occurs in the direction perpendicular to the mounting surface of the upward tilting door's moving mechanism. This affects the stability of the upward tilting door's moving mechanism, and consequently affects the accuracy of the door's closed position, leading to problems such as interference between the door and the housing. Summary of the Invention

[0007] To overcome at least one of the defects described in the prior art, this application provides a door moving device with anti-shake function. The first connection point, the second connection point, and the third connection point form a relatively stable three-point connection with the cabinet, which can support a door with a large mass. The stable three-point connection can prevent the hinge mechanism and the door from shaking during opening and closing, thereby avoiding interference between the door and the cabinet. When the wheel moves to different curvature positions within a certain angle range of the curved track, the door can be suspended under the support of the elastic mechanism.

[0022] The hinge mechanism is located beside the elastic mechanism, and the modular damper is located below the elastic mechanism.

[0023] When the hinge mechanism is closed, the second link acts on the modular damper.

[0024] In a preferred embodiment, the elastic mechanism includes an elastic element, an elastic adjusting block, and an adjusting screw. One end of the elastic element is connected to the elastic adjusting block, and the other end of the elastic element is connected to the slider. The elastic adjusting block is sleeved on the adjusting screw, and the elastic adjusting block is threadedly connected to the adjusting screw.

[0025] The mounting base is provided with a first slide rail and a second slide rail. The slider is slidably connected to the first slide rail, and the elastic adjustment block is slidably connected to the second slide rail.

[0026] By rotating the adjusting screw, the elastic adjusting block moves closer to or further away from the slider, thereby changing the compression of the elastic element.

[0027] In a preferred embodiment, the elastic mechanism further includes an adjusting seat and an adjusting gear, the adjusting gear being rotatably connected to the adjusting seat;

[0028] The adjusting gear is provided with a first adjusting tooth, and the end of the adjusting screw is provided with a second adjusting tooth. The first adjusting tooth and the second adjusting tooth mesh with each other. The adjusting gear is set perpendicular to the adjusting screw.

The position adjusting seat is provided with an adjusting groove, and the locking screw passes through the adjusting groove and is connected and fixed to the position fixing seat.

When the wheel moves to different curvature positions within a certain angle range of the curved track, the door can be suspended under the support of the elastic mechanism.

Detailed Implementation

[0041] To better understand and implement this application, the technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings.

[0042] In the description of this application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0044] Referring to Figures 1-8, this application discloses a door moving device with anti-shake function, including: a mounting base 10 for mounting on a cabinet 20; a slider 30 slidably connected to the mounting base 10, the slider 30 having a curved track 40; a spring mechanism 50, the spring force of the spring mechanism 50 acting on the slider 30; and 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. The first end of the first link 601 is rotatably connected to the mounting base 10 to form a first connection point, the first end of the second link 602 is rotatably connected to the mounting base 10 to form a second connection point, the second end of the second link 602 is provided with a wheel 605, the wheel 605 moves along the curved track 40 to form a third connection point, the first end of the third link 603 is rotatably connected to the door 70 to form a fourth connection point, and the first end of the fourth link 604 is rotatably connected to the door 70 to form a fifth connection point.

[0045] Based on the above structure, the first end of the first link 601 in this application is rotatably connected to the mounting base 10 to form a first connection point, the first end of the second link 602 is rotatably connected to the mounting base 10 to form a second connection point, and the wheel 605 moves along the curved track 40 to form a third connection point. The first connection point, the second connection point, and the third connection point are rotatable connection points, and the third connection point is a sliding connection point. When this application is used, the first connection point, the second connection point, and the third connection point form a relatively stable three-point connection with the cabinet 20, ensuring the stability and accuracy of the hinge mechanism 60's operation, and thus enabling it to support the door 70, which has a larger mass. The aforementioned stable three-point connection can prevent the hinge mechanism 60 and the door 70 from shaking during opening and closing, and prevent interference between the door 70 and the cabinet 20. When the wheel 605 moves to different curvature positions within a certain angle range of the curved track 40, the door 70 can be suspended under the support of the elastic mechanism 50.

[0046] It should be noted that the elastic force of the elastic mechanism 50 acts on the door 70 through the slider 30, the wheel 605, and the hinge mechanism 60 to provide support for the door 70, thereby enabling the door 70 to be suspended. The above-mentioned suspension refers to the state in which the door 70 is opened relative to the cabinet 20 and stops at a certain opening angle after the door 70 is connected to the cabinet 20 through the hinge mechanism 60.

[0047] Since the first end of the third link 603 is used to rotatably connect with the door body 70 to form a fourth connection point, and the first end of the fourth link 604 is used to rotatably connect with the door body 70 to form a fifth connection point, the hinge mechanism 60 is rotatably connected with the door body 70 through the fifth connection point and the sixth connection point.

[0048] When the lines connecting the first connection point, the second connection point, and the third connection point are not on the same line, a relatively stable triangular connection is formed between the first connection point, the second connection point, the third connection point, and the cabinet 20.

[0049] In this embodiment of the application, the second end of the first link 601 is rotatably connected to the middle part of the fourth link 604, the middle part of the second link 602 is rotatably connected to the second end of the fourth link 604, and the third end of the second link 602 is rotatably connected to the second end of the third link 603.

[0050] Furthermore, during the opening or closing of the hinge mechanism 60, the first link 601 and the second link 602 always remain parallel or approximately parallel to each other, and the third link 603 and the fourth link 604 always remain parallel or approximately parallel to each other. Compared with the cross-link hinge mechanism formed by three links, this hinge mechanism 60 has better stability, its force is more even, and the opening or closing process of the hinge mechanism 60 is smoother, avoiding jamming.

[0051] In this embodiment, the second link 602 is rotatably connected to the wheel 605, and the second link 602 is nested with the slider 30; so that during the movement of the wheel 605 along the curved track 40, the outer contour of the wheel 605 abuts against the outer contour of the curved track 40, and at least one side of the second link 602 limits the slider 30 in a direction perpendicular to the mounting surface of the mounting base 10.

[0052] In this embodiment, the second connecting rod 602 extends outward on both sides of the wheel body 605 and is provided with limiting side plates 606. A limiting groove 607 is formed between the two limiting side plates 606, and the slider 30 is embedded in the limiting groove 607, as shown in Figure 4.

[0053] In other embodiments, limiting side plates 606 extend outward from both sides of the slider 30, and a limiting groove 607 is formed between the two limiting side plates 606, with the wheel 605 embedded in the limiting groove 607.

[0054] Furthermore, a buffer element 608 is provided on the limiting side plate 606. For example, the buffer element 608 can be a silicone pad, a rubber pad, etc., to reduce the impact force between the second connecting rod 602 and the slider 30.

[0055] Taking the mounting base 10 installed on the inner cavity side of the cabinet 20 as an example, referring to Figure 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 connecting rod 602 in the X direction, thereby further improving the stability of the hinge mechanism 60 and further preventing it from shaking.

[0056] In order to achieve relative movement between the wheel 605 and the slider 30, and to limit the second connecting rod 602 in the X direction, there is an installation gap between the slider 30 and the limiting slot 607 or between the second connecting rod 602 and the limiting slot 607. The installation gap is as small as possible while ensuring that relative movement between the wheel 605 and the slider 30 can be achieved. For example, the installation gap is a, where a is 1mm-2mm.

[0057] During installation, an installation groove can be set on the inner side of the cabinet 20, and the mounting base 10 can be installed in the installation groove, thereby avoiding occupying the internal space of the cabinet 20 and achieving concealed installation.

[0058] Furthermore, the door moving device with anti-shake function also includes a first pin 609, a second pin 610, a third pin 611, a fourth pin 612, a fifth pin 613, a sixth pin 614, a seventh pin 615, and an eighth pin 616.

[0059] The first end of the first link 601 is rotatably connected to the mounting base 10 via the first pin 609 to form a first connection point. The first end of the second link 602 is rotatably connected to the mounting base 10 via the second pin 610 to form a second connection point. The second end of the second link 602 is provided with a wheel 605. The second end of the second link 602 is rotatably connected to the wheel 605 via the third pin 611. The first end of the third link 603 is rotatably connected to the door body 70 via the fourth pin 612 to form a fourth connection point. The first end of the fourth link 604 is rotatably connected to the door body 70 via the fifth pin 613 to form a fifth connection point. The second end of the first link 601 is rotatably connected to the middle of the fourth link 604 via the sixth pin 614. The middle of the second link 602 is rotatably connected to the second end of the fourth link 604 via the seventh pin 615. The third end of the second link 602 is rotatably connected to the second end of the third link 603 via the eighth pin 616.

[0060] In this embodiment of the application, the mounting base 10 includes a back plate 101 and a front panel 102. The second connecting rod 602 is provided with a support protrusion 617 on the side facing the back plate 101 and the side facing the front panel 102.

[0061] Specifically, the back plate 101 and the front panel 102 are fastened together to form a mounting base 10, and the hinge mechanism 60 and the elastic mechanism 50 are hidden in the space between the back plate 101 and the front panel 102, thereby protecting the hinge mechanism 60 and the elastic mechanism 50.

[0062] By using the support protrusion 617 to reduce the gap between the second link 602 and the back plate 101 and the front panel 102, the swaying of the hinge mechanism 60 in the X direction during operation is reduced. Compared with the solution of thickening the second link 602 as a whole, the use of the support protrusion 617 can reduce costs and facilitate the assembly of the second link 602 onto the mounting base 10.

[0063] In this embodiment of the application, the curved track 40 includes at least two arc-shaped track segments, with a smooth transition between the two arc-shaped track segments.

[0064] It should be noted that the actual trajectory of the arc-shaped track segment is adapted to the running trajectory of the hinge mechanism 60 and the opening angle of the door 70. As the elastic mechanism 50 drives the slider 30 to press against the wheel 605, during the opening or closing of the door 70, the outer contour of the wheel 605 abuts against the outer contour of the curved track 40, and the point of tangency between the wheel 605 and the curved track 40 changes with the operation of the hinge mechanism 60. That is, the wheel 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., without limitation.

[0065] In this embodiment, the door moving device with anti-shaking function further includes a modular damper 80, which is detachably connected to the mounting base 10; the hinge mechanism 60 is disposed on the side of the elastic mechanism 50, and the modular damper 80 is disposed below the elastic mechanism 50; when the hinge mechanism 60 is closed, the second link 602 acts on the modular damper 80.

[0066] It should be noted that the modular damper 80 can directly use existing dampers and integrate them on the base to form the modular damper 80; the modular damper 80 is detachably connected to the mounting base 10 by screws, and the modular damper 80 can be replaced by removing and installing screws to suit different application scenarios.

[0067] When the door 70 is closed, the hinge mechanism 60 also closes. The second link 602 acts on the modular damper 80, thereby enabling the door 70 to close slowly, avoiding impact on the cabinet 20 when the door 70 closes, and achieving damped closing.

[0068] In this embodiment, the elastic mechanism 50 includes an elastic element 501, an elastic adjusting block 502, and an adjusting screw 503. One end of the elastic element 501 is connected to the elastic adjusting block 502, and the other end of the elastic element 501 is connected to the slider 30. The elastic adjusting block 502 is sleeved on the adjusting screw 503, and the elastic adjusting block 502 is threadedly connected to the adjusting screw 503. The mounting base 10 is provided with a first slide rail 103 and a second slide rail 104. The slider 30 is slidably connected to the first slide rail 103, and the elastic adjusting block 502 is slidably connected to the second slide rail 104. By rotating the adjusting screw 503, the elastic adjusting block 502 is moved closer to or further away from the slider 30 to change the compression amount of the elastic element 501.

[0069] When the door 70 is closed to the cabinet 20, the hinge mechanism 60 closes, pushing the slider 30 closer to the spring adjustment block 502, thereby compressing the spring element 501. When the door 70 is opened to the cabinet 20, the hinge mechanism 60 opens, pushing the slider 30 away from the spring adjustment block 502, thereby resetting the spring element 501. The spring element 501 provides a supporting force to the door 70 through the hinge mechanism 60, allowing the door 70 to stop at a certain angle of opening, preventing it from being directly reset to the closed position due to its own weight. The elasticity of the spring element 501 is adapted to the weight of the door 70, with the aim of supporting the door 70. The elasticity of the spring element 501 can be selected according to the actual application scenario.

[0070] In this embodiment, the elastic mechanism 50 further includes an adjusting seat 504 and an adjusting gear 505, which is rotatably connected to the adjusting seat 504. The adjusting gear 505 is provided with a first adjusting tooth 506, and the end of the adjusting screw 503 is provided with a second adjusting tooth 507. The first adjusting tooth 506 and the second adjusting tooth 507 mesh with each other. The adjusting gear 505 is arranged perpendicular to the adjusting screw 503. By rotating the adjusting gear 505, the adjusting screw 503 is driven to rotate.

[0071] Specifically, the first slide rail 103, the second slide rail 104, and the adjusting seat 504 are all connected and fixed to the mounting base 10. The first slide rail 103, the second slide rail 104, and the adjusting seat 504 can all be connected and fixed to the mounting base 10 by screws or welding. The specific connection and fixing method depends on the actual situation and is not limited. The adjusting seat 504 is located between the slider 30 and the elastic adjusting block 502, and the specific setting position of the adjusting seat 504 is based on not interfering with the movement of the slider 30 and the elastic adjusting block 502.

[0072] Specifically, the elastic element 501 is a straight tube spring or elastic silicone; in order to realize the directional extension and retraction of the elastic element 501, guide posts 508 are provided on the slider 30 and the elastic adjustment block 502, and the elastic element 501 is sleeved on the guide post 508, and the extension and retraction of the elastic element 501 is guided by the guide post 508.

[0073] The specific adjustment process for the compression of the elastic element 501 is as follows:

[0074] By rotating the adjusting gear 505 in the forward direction, the adjusting screw 503 is driven to rotate in the forward direction, thereby moving the elastic adjusting block 502 away from the slider 30, thus reducing the compression of the elastic element 501. If the elastic element 501 needs to be replaced, it can be rotated in the forward direction until the elastic adjusting block 502 is completely disengaged from the adjusting screw 503, thus allowing the elastic element 501 to be replaced. By rotating the adjusting gear 505 in the reverse direction, the adjusting screw 503 is driven to rotate in the reverse direction, thereby moving the elastic adjusting block 502 closer to the slider 30, thus increasing the compression of the elastic element 501.

[0075] When the elastic element 501 is replaceable, one end of the elastic element 501 abuts against the slider 30, and the other end of the elastic element 501 abuts against the elastic adjustment block 502.

[0076] The aforementioned forward rotation is clockwise rotation, and reverse rotation is counterclockwise rotation; or, the aforementioned forward rotation is counterclockwise rotation, and reverse rotation is clockwise rotation; the choice is made according to the actual application scenario and is not limited thereto.

[0077] In this embodiment of the application, the door moving device with anti-shaking function further includes a position adjuster 90. The position adjuster 90 includes a locking screw (not shown in the figure), a position fixing seat 901, and a position adjusting seat 902. The position fixing seat 901 is used to connect and fix to the door body 70. The first end of the third link 603 and the first end of the fourth link 604 are rotatably connected to the position adjusting seat 902. The position adjusting seat 902 is provided with an adjusting groove 903. The locking screw passes through the adjusting groove 903 and connects and fixes to the position fixing seat 901.

[0078] Since the hinge mechanism 60 requires its two ends to be installed on the cabinet 20 and the door 70 respectively during installation, and the cabinet 20 and the door 70 need to be aligned, the position adjuster 90 is used to reduce the number of calibrations between the cabinet 20 and the door 70. During installation, the first link 601 and the second link 602 of the hinge mechanism 60 are first installed on the cabinet 20, then the position fixing seat 901 of the position adjuster 90 is installed, and the third link 603 and the fourth link 604 of the hinge mechanism 60 are installed on the position adjusting seat 902.
