Description

Technical Field

[0001] The invention relates to the field of hardware accessories, and in particular to a door moving device with an anti-swaying function. Background Art

[0002] During use, the door body moves relative to the fixed structure on which the door body is installed, so that the door body moves in an opening direction or in a closing direction. There are various devices for moving the door bodies of different types of furniture.

[0003] Chinese patent CN118591675A discloses a moving mechanism for an upwardly tilted door, which is suitable for being arranged on the side of a piece of furniture or inside the side, the mechanism being housed in a box body consisting of two half shells and comprising a hinge with five points, the hinge consisting of three rods, the rods being hinged to each other at a fulcrum, the fulcrum being arranged in one of the middle regions of the rods, one end of the rod being hinged to one end of the rod at the fulcrum, the other end of the rod being hinged to the door at the point, one end of the rod being hinged to the door at the point, and the other end of the rod being provided with a pin sliding in a track formed in the box body, the rod being also hinged to the box body at the fulcrum, the rod rotating around the fulcrum during movement of the door body, characterized in that the rod acts directly or indirectly on a cam profile of a linear slider, the linear slider being subjected to the direct action of an elastic device, thereby generating a force tending to open the mechanism and thereby supporting the weight of the door body.

[0004] The patent discloses a technical solution of using a rod to act directly or indirectly on the cam profile of a linear slider: In the technical solution in which the rod indirectly acts on the cam profile of the linear slider, there are five connection points between the hinge and the box body, namely the fulcrum, the rotation center, 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 combined connection mode of two rotating connection points and three sliding connection points leads to a stronger overall stability of the structure, but the hinge needs to cooperate with the push rod and the rod. The push rod and the box body, the push rod and the rod, and the rods need to cooperate, which makes the overall structure more complicated, increasing the difficulty of assembly and production cost.

[0005] In the technical solution in which the rod acts directly on the cam profile of the linear slider, there are only three connection points between the hinge and the box body, namely, the fulcrum, 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. Two of the three connection points are sliding connection points and one rotation connection point. During the movement of the hinge, since the two connection points between it and the box body are both sliding connection points, and both of the two sliding connection points lack position limits in a direction perpendicular to the mounting surface where the moving mechanism of the upward-tilted door is located, when the size of the door connected to the moving mechanism of the upward-tilted door is large, a certain degree of shaking is generated in a direction perpendicular to the mounting surface where the moving mechanism of the upward-tilted door is located, affecting the stability of the operation of the moving mechanism of the upward-tilted door, and further affecting the accuracy of the door connected to the moving mechanism of the upward-tilted door in the closed position, resulting in interference between the door and the box body.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] See also Figure 1-Figure 8The present invention discloses a door moving device with an anti-sway function, comprising: a mounting seat 10, the mounting seat 10 is used to be mounted on a cabinet body 20; a slider 30, the slider 30 is slidably connected to the mounting seat 10, and the slider 30 has a curved track 40; an elastic mechanism 50, the elastic force of the elastic mechanism 50 acts on the slider 30; a hinge mechanism 60, the hinge mechanism 60 comprises a first connecting rod 601, a second connecting rod 602, a third connecting rod 603 and a fourth connecting rod 604, the first end of the first connecting rod 601 is rotatably connected to the mounting seat 10 to form a first connecting point, the first end of the second connecting rod 602 is rotatably connected to the mounting seat 10 to form a second connecting point, the second end of the second connecting rod 602 is provided with a wheel body 605, the wheel body 605 moves along the curved track 40 to form a third connecting point, the first end of the third connecting rod 603 is used to be rotatably connected to the door body 70 to form a fourth connecting point, and the first end of the fourth connecting rod 604 is used to be rotatably connected to the door body 70 to form a fifth connecting point.

[0024] Based on the above structure, the first end of the first connecting rod 601 in the present invention is rotatably connected to the mounting seat 10 to form a first connection point, the first end of the second connecting rod 602 is rotatably connected to the mounting seat 10 to form a second connection point, and the wheel body 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 rotating connection points, and the third connection point is a sliding connection point; when the present invention is used, a relatively stable three-point connection method is formed between the first connection point, the second connection point and the third connection point and the cabinet body 20, thereby ensuring the stability and accuracy of the operation of the hinge mechanism 60, and thus being able to carry a door body 70 with a larger mass. The above-mentioned stable three-point connection method can avoid shaking during the opening and closing of the hinge mechanism 60 and the door body 70, and avoid mutual interference between the door body 70 and the cabinet body 20; when the wheel body 605 moves to different curvature positions within a certain angle range of the curved track 40, the wheel body 605 can be supported by the elastic mechanism 50, and the door body 70 can be suspended.

[0025] It should be noted that the elastic force of the elastic mechanism 50 acts on the door body 70 through the slider 30, the wheel body 605, and the hinge mechanism 60 to provide supporting force for the door body 70, so that the door body 70 can hover; the above-mentioned hovering refers to the state that after the door body 70 is connected to the cabinet body 20 through the hinge mechanism 60, the door body 70 opens relative to the cabinet body 20 and stops at a certain opening angle.

[0026] Since the first end of the third connecting rod 603 is used to be rotatably connected to the door body 70 to form a fourth connection point, and the first end of the fourth connecting rod 604 is used to be rotatably connected to the door body 70 to form a fifth connection point, the hinge mechanism 60 is rotatably connected to the door body 70 via the fifth connection point and the sixth connection point.

[0027] When the connection lines between the first connection point, the second connection point and the third connection point are not on the same line, a relatively stable triangle connection is formed between the first connection point, the second connection point and the third connection point and the cabinet 20 .

[0028] In the embodiment of the present invention, the second end of the first connecting rod 601 is rotatably connected to the middle part of the fourth connecting rod 604, the middle part of the second connecting rod 602 is rotatably connected to the second end of the fourth connecting rod 604, and the third end of the second connecting rod 602 is rotatably connected to the second end of the third connecting rod 603.

[0029] Furthermore, during the opening or closing process 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 a cross-rod hinge mechanism formed by three links, the present hinge mechanism 60 has better stability, its force is more uniform, and the opening or closing process of the hinge mechanism 60 is smoother, avoiding jamming.

[0030] In an embodiment of the present invention, the second connecting rod 602 is rotatably connected to the wheel body 605, and the second connecting rod 602 is nested with the slider 30; so that when the wheel body 605 moves along the curved track 40, the outer contour of the wheel body 605 abuts against the outer contour of the curved track 40, and at least one side portion of the second connecting rod 602 limits the slider 30 in a direction perpendicular to the mounting surface of the mounting seat 10.

[0031] In the embodiment of the present invention, the second connecting rod 602 is provided with a limiting side plate 606 extending outwardly on both sides of the wheel body 605, and a limiting slot 607 is formed between the two limiting side plates 606, and the slider 30 is embedded in the limiting slot 607. Figure 4 .

[0032] Or in other embodiments, limiting side plates 606 are extended outwardly from both sides of the slider 30 , a limiting slot 607 is formed between the two limiting side plates 606 , and the wheel body 605 is embedded in the limiting slot 607 .

[0033] 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., so as to reduce the impact force between the second connecting rod 602 and the slider 30 .

[0034] The installation of the mounting base 10 on the inner side of the cabinet 20 is used as an example for description. Figure 3 The direction perpendicular to the mounting surface of the mounting seat 10 is the X direction, and the slider 30 is used to limit the second connecting rod 602 in the X direction, thereby further improving the operating stability of the hinge mechanism 60 and further preventing it from shaking.

[0035] In order to realize the relative movement between the wheel body 605 and the slider 30 and the limitation of the second connecting rod 602 in the X direction by the slider 30, 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 the relative movement between the wheel body 605 and the slider 30. For example, the installation gap is a, and a is 1mm-2mm.

[0036] During installation, a mounting groove may be provided on the inner side of the cabinet 20 , and the mounting seat 10 may be installed in the mounting groove, thereby avoiding occupying the inner space of the cabinet 20 , thereby achieving concealed installation.

[0037] Furthermore, the door moving device with anti-sway 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 .

[0038] The first end of the first connecting rod 601 is rotatably connected to the mounting seat 10 through the first pin shaft 609 to form a first connection point, the first end of the second connecting rod 602 is rotatably connected to the mounting seat 10 through the second pin shaft 610 to form a second connection point, the second end of the second connecting rod 602 is provided with a wheel body 605, the second end of the second connecting rod 602 is rotatably connected to the wheel body 605 through the third pin shaft 611, the first end of the third connecting rod 603 is rotatably connected to the door body 70 through the fourth pin shaft 612 to form a fourth connection point, the first end of the fourth connecting rod 604 is rotatably connected to the door body 70 through the fifth pin shaft 613 to form a fifth connection point; the second end of the first connecting rod 601 is rotatably connected to the middle part of the fourth connecting rod 604 through the sixth pin shaft 614, the middle part of the second connecting rod 602 is rotatably connected to the second end of the fourth connecting rod 604 through the seventh pin shaft 615, and the third end of the second connecting rod 602 is rotatably connected to the second end of the third connecting rod 603 through the eighth pin shaft 616.

[0039] In the embodiment of the present invention, the mounting base 10 includes a back plate 101 and a panel 102 , and a supporting protrusion 617 is provided on the side of the second connecting rod 602 facing the back plate 101 and the side of the second connecting rod 602 facing the panel 102 .

[0040] Specifically, the back plate 101 and the panel 102 are buckled together to form the mounting seat 10 , and the hinge mechanism 60 and the elastic mechanism 50 are hidden in the space between the back plate 101 and the panel 102 , so as to protect the hinge mechanism 60 and the elastic mechanism 50 .

[0041] The support protrusion 617 is used to reduce the gap between the second connecting rod 602 and the back plate 101 and the panel 102, thereby reducing the shaking of the hinge mechanism 60 in the X direction during operation. Compared with the solution of thickening the second connecting rod 602 as a whole, the support protrusion 617 can reduce costs and facilitate the assembly of the second connecting rod 602 on the mounting base 10.

[0042] In the embodiment of the present invention, the curved track 40 includes at least two arc-shaped track segments, and there is a smooth transition between the two arc-shaped track segments.

[0043] It should be noted that the actual trajectory of the arc track segment is adapted 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 the wheel body 605, during the process of opening or closing the door body 70, the outer contour of the wheel body 605 and the outer contour of the curved track 40 are in contact with each other, and the tangent point between the wheel body 605 and the curved track 40 changes with the operation of the hinge mechanism 60, that is, the wheel body 605 moves at different curvature positions of the curved track 40; therefore, according to the actual application scenario, the curved track 40 includes two arc track segments, three arc track segments, four arc track segments, etc., and is not limited.

[0044] In an embodiment of the present invention, the door moving device with anti-sway function also includes a modular damper 80, which is detachably connected to the mounting base 10; the hinge mechanism 60 is arranged beside the elastic mechanism 50, and the modular damper 80 is arranged below the elastic mechanism 50; when the hinge mechanism 60 is closed, the second connecting rod 602 acts on the modular damper 80.

[0045] It should be noted that the modular damper 80 can directly adopt the existing damper, and the damper can be integrated on the machine base to form a 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 disassembling and assembling the screws to adapt to different application scenarios.

[0046] When the door body 70 is closed, the hinge mechanism 60 is also closed, and the second connecting rod 602 acts on the modular damper 80, so that the door body 70 can be closed slowly, avoiding the door body 70 from impacting the cabinet body 20 when closing, and realizing damping door closing.

[0047] In an embodiment of the present invention, the elastic mechanism 50 includes an elastic element 501, an elastic adjustment block 502 and an adjusting screw 503, one end of the elastic element 501 is connected to the elastic adjustment block 502, the other end of the elastic element 501 is connected to the slider 30, the elastic adjustment block 502 is sleeved on the adjusting screw 503, and the elastic adjustment block 502 is threadedly connected to the adjusting screw 503; a first slide rail 103 and a second slide rail 104 are provided on the mounting seat 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 elastic adjustment block 502 is driven to move closer to or away from the slider 30 by rotating the adjusting screw 503 to change the compression amount of the elastic element 501.

[0048] When the door body 70 and the cabinet body 20 are closed, the hinge mechanism 60 is closed, pushing the slider 30 close to the elastic force adjustment block 502, so that the elastic element 501 is compressed; when the door body 70 and the cabinet body 20 are opened, the hinge mechanism 60 is opened, pushing the slider 30 away from the elastic force adjustment block 502, so that the elastic element 501 is reset. The elastic element 501 provides a supporting force for the door body 70 through the hinge mechanism 60, so that the door body 70 can stop at a certain opening angle to avoid being directly reset to the closed position due to the gravity of the door body 70 itself; the elastic force of the elastic element 501 is adapted to the gravity of the door body 70, so as to be able to support the door body 70. The elastic force of the elastic element 501 can be selected according to the actual application scenario.

[0049] In an embodiment of the present invention, the elastic mechanism 50 also includes an adjusting seat 504 and an adjusting gear 505, and the adjusting gear 505 is rotatably connected to the adjusting seat 504; a first adjusting tooth 506 is provided on the adjusting gear 505, and a second adjusting tooth 507 is provided at the end of the adjusting screw 503, the first adjusting tooth 506 and the second adjusting tooth 507 are meshed with each other, and the adjusting gear 505 is arranged vertically to the adjusting screw 503, and the adjusting screw 503 is driven to rotate by rotating the adjusting gear 505.

[0050] Specifically, the first slide rail 103, the second slide rail 104 and the adjustment seat 504 are all connected and fixed to the mounting seat 10. The first slide rail 103, the second slide rail 104 and the adjustment seat 504 can be connected and fixed to the mounting seat 10 by screw connection or welding. The specific connection and fixing method depends on the actual situation and is not limited. The adjustment seat 504 is arranged between the slider 30 and the elastic adjustment block 502, and the specific setting position of the adjustment seat 504 is based on not interfering with the movement of the slider 30 and the elastic adjustment block 502.

[0051] Specifically, the elastic element 501 is a straight tube spring or elastic silicone; in order to achieve directional expansion and contraction of the elastic element 501, a guide column 508 is provided on the slider 30 and the elastic adjustment block 502, and the elastic element 501 is sleeved outside the guide column 508, and the guide column 508 is used to guide the expansion and contraction of the elastic element 501.

[0052] The specific adjustment process of the compression amount of the elastic element 501 is as follows: By rotating the adjusting gear 505 forward, the adjusting screw 503 is driven to rotate in the forward direction, thereby driving the elastic force adjusting block 502 away from the slider 30, so that the compression of the elastic element 501 is reduced; if the elastic element 501 needs to be replaced, it can be rotated forward until the elastic force adjusting block 502 is completely disengaged from the adjusting screw 503, so that the elastic element 501 can be replaced; by rotating the adjusting gear 505 backward, the adjusting screw 503 is driven to rotate in the reverse direction, thereby driving the elastic force adjusting block 502 close to the slider 30, so that the compression of the elastic element 501 is increased.

[0053] 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 force adjustment block 502 .

[0054] The above-mentioned forward rotation is clockwise rotation, and the reverse rotation is counterclockwise rotation; or, the above-mentioned forward rotation is counterclockwise rotation, and the reverse rotation is clockwise rotation; the selection is made according to the actual application scenario and is not limited.

[0055] In an embodiment of the present invention, the door moving device with anti-sway function also includes a position adjuster 90, which includes a locking screw (not shown in the accompanying drawings), a position fixing seat 901 and a position adjustment seat 902. The position fixing seat 901 is used to be connected and fixed to the door body 70. The first end of the third connecting rod 603 and the first end of the fourth connecting rod 604 are both rotatably connected to the position adjustment seat 902. An adjustment groove 903 is provided on the position adjustment seat 902, and the locking screw passes through the adjustment groove 903 and is connected and fixed to the position fixing seat 901.

[0056] When the hinge mechanism 60 is installed, the two ends of the hinge mechanism 60 need to be installed on the cabinet 20 and the door body 70 respectively, and the cabinet 20 and the door body 70 need to be aligned; the position adjuster 90 is provided to reduce the number of calibrations between the cabinet 20 and the door body 70. During installation, the first connecting rod 601 and the second connecting rod 602 of the hinge mechanism 60 are first installed on the cabinet 20, and then the position fixing seat 901 of the position adjuster 90 is installed, and the third connecting rod 603 and the fourth connecting rod 604 of the hinge mechanism 60 are installed on the position adjustment seat 902.
