Description

Cup-shaped concealed hinge TECHNICAL FIELD

[0001] The present application relates to the technical field of hinges, in particular to a cup-shaped concealed hinge. BACKGROUND

[0002] The cup-shaped concealed hinge is a hardware commonly used in modern furniture, which is designed to connect cabinet doors and cabinet bodies. It not only realizes smooth opening and closing, but also hides inside the cabinet door, maintaining the simple appearance of furniture. However, the existing cup-shaped concealed hinge cannot adjust the position of the damping device, and can only produce buffering at a fixed angle, which will lead to the inability to optimize the buffering effect of the cabinet door at different opening angles. And within the fixed buffering angle range, the damping device of the cup-shaped concealed hinge will bear a higher frequency of load, leading to accelerated wear. At other angles, due to the lack of buffering, the closing speed of the cabinet door is faster, and the impact force is larger, which will also accelerate the wear of the overall structure.

DETAILED DESCRIPTION

[0053] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0054] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above-mentioned accompanying drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the terms thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units need not be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0055] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be noted that the exemplary embodiments can be implemented in various different forms, and should not be construed as being limited to the embodiments set forth herein.

[0056] As shown in FIGS. 1-15, the cup-shaped hinge can include a hinge arm 100, a connecting member, a hinge cup 400, a damping device 500, and an adjusting device 600. In some embodiments, a damping switch 700 and a dismounting frame 800 can also be included.

[0057] The connecting member is hingedly connected between the hinge arm 100 and the hinge cup 400, and includes a first connecting member 200 and a second connecting member 300. In some embodiments, the first connecting member 200 and the second connecting member 300 are collectively hingedly connected to the hinge cup 400 by a U-shaped pin 410. The hinge cup 400 can be fixed to a door / frame by a bolt or the like, and the hinge arm 600 can be clamped and fixed to a base by an embedded dismounting frame 800, and then fixed to the frame / door by the base.

[0058] The damping device 500 is slidably located in the hinge arm 100. The damping device 500 functions to effectively slow down the opening and closing speed of the cabinet door by slowly releasing the accumulated energy, providing a soft closing experience, and preventing impact and noise caused by forceful closing.

[0059] The adjusting device 600 is inserted into one side of the hinge arm 100. The adjusting device 600 is installed on one side wall of the hinge arm 100, and controls the reset stroke of the damping device 500 by changing the position of the damping device 500.

[0060] The end side of the second connecting member 300 is provided with a tail hook 310, which is used to rotate around an axis and come into contact with the damping device 500 when the hinge is within a preset angle range, so that the damping device 500 is used to slow down the opening and closing speed of the hinge. A moderate damping force is generated by the interaction of the tail hook 310 and the damping device 500, so that the hinge can gradually slow down when closing.

[0061] The adjusting device 600 is used to adjust the maximum stroke position of the damping device 500 in the hinge arm 100, so as to adjust the maximum damping stroke, which refers to the maximum displacement distance at which the damping device can provide effective damping action. By adjusting the maximum stroke position of the damping device 500 in the hinge arm 100 by the adjusting device 600, the tail hook 310 and the damping device 500 come into contact at different angles to form a buffering effect when the hinge is closed.

[0062] In this embodiment, as shown in Figs. 15 and 16, the maximum stroke position of the damping device 500 in the hinge arm 100 changes from the state without adjustment (Fig. 15) to the state with adjustment by the adjustment device 600 (Fig. 16), and thus the hinge needs to rotate a larger angle to make the tail hook 310 abut against the damping device 500. Therefore, by adjusting the maximum stroke position of the damping device 500 in the hinge arm 100 by the adjustment device 600, the maximum damping stroke is adjusted, the damping angle when the hinge is closed is changed, and thus the closing time of the hinge is changed, so as to meet different requirements of users on the closing time of the cabinet door. The damping angle refers to the angle during which the damping effect is exerted in a certain rotation or movement.

[0063] In an optional embodiment, the adjustment device 600 comprises a first rotating part 610 and a second rotating part 620. The first rotating part 610 is provided with a rotating switch 612 and a rotating shaft 611, and the rotating shaft 611 extends into the hinge arm 100 and is fixedly connected with the second rotating part 620. The rotating switch 612 can be provided with a cross-shaped recess for convenient installation. The rotating shaft 611 can be a column with a triangular or polygonal cross section, and the second rotating part 620 is provided with a plug hole matched with the rotating shaft 611. The first rotating part 610 and the second rotating part 620 are fixedly connected by inserting the rotating shaft 611 into the plug hole. The first rotating part 610 and the second rotating part 620 can also be fixedly connected by means of bolts or buckles.

[0064] The second rotating part 620 is provided with a flange part 621, and the damping device 500 is provided with a first protruding part 510 abutting against the flange part 621. The flange part 621 can be a smooth curved surface structure, which can smoothly extrude other components during rotation.

[0065] In the actual operation, the user can rotate the rotating switch 612 to rotate the second rotating part 620 through the rotating shaft 611. When the second rotating part 620 rotates to a preset angle, the flange part 621 gradually contacts the first protruding part 510 and applies a certain pressing force. The pressing force is transmitted to the damping device 500 through the first protruding part 510, so that the relative position of the damping device 500 in the hinge arm 100 changes.

[0066] In the optional embodiment, the user can more accurately control the maximum stroke position of the damping device 500 through this adjustment mode, so as to more accurately adjust the maximum damping stroke, more accurately change the damping angle when the hinge is closed, and more accurately change the closing time of the hinge, so as to accurately meet the different needs of the user for the closing time of the cabinet door.

[0067] In the optional embodiment, the second rotating part 620 is a semicircular pie structure that is cut in a part, and the flange part 621 is located at the arc edge of the semicircular pie structure.

[0068] In the embodiment, the semicircular pie structure that is cut in a part can avoid the cut part from being in contact with the first protrusion 510 in advance, and the flange part 621 located at the arc edge of the semicircular pie structure helps to reduce the friction with the first protrusion 510 during rotation.

[0069] In the optional embodiment, the outer edge of the flange part 621 is partially elliptical. This can uniformly distribute the pressure when the flange part 621 is in contact with the first protrusion part 510, can linearly increase or decrease the maximum damping stroke, and can infinitely select a value between the maximum and minimum values of the damping stroke without jumping to a certain fixed gear.

[0070] In the optional embodiment, the second rotating part 620 is an elliptical pie structure, and the flange part 621 is located at the end structure corresponding to the major axis of the elliptical pie structure.

[0071] In the optional embodiment, a plurality of damping scale lines 130 are located outside the hinge arm 100 and are distributed around the rotating switch 612. The damping scale lines can be marked with different colors or lengths to facilitate the user to quickly identify.

[0072] One side edge of the rotating switch 612 is provided with an arrow indicating mark. The shape of the arrow can clearly point to the currently selected damping scale line 130.

[0073] Wherein, the arrow indicating mark points to different damping scale lines 130, which represents the current damping effect of the damping device 500. The user can change the direction of the arrow by rotating the rotating switch 612, so as to more intuitively adjust the closing speed of the cabinet door.

[0074] In the embodiment, a plurality of damping scale lines 130 are uniformly arranged on the outer surface of the hinge arm 100, and these scale lines are distributed around the rotating switch 612 to form a precise scale disc. Each scale line corresponds to a specific damping setting, so that the user can intuitively understand and adjust the working state of the damping device 500.

[0075] In an optional embodiment, the damping device 500 is provided with a second protruding portion 520 on the side of the damping device 500, which is used to be hooked with the tail hook 310. The second protruding portion 520 is used to be hooked with the tail hook, and when the hinge is rotated to a certain angle, the tail hook 310 will hook the second protruding portion 520, thereby triggering the damping device 500 to generate damping force.

[0076] The hinge arm 100 is provided with a blocking portion 120 matched with the third protruding portion 530, which is used to limit the maximum stroke of the damping device 500. The blocking portion 120 can be a pin located inside the hinge arm 100, and can also provide support for the damping device 500 inside the hinge arm 100. When the damping device 500 moves along the hinge arm 100, the third protruding portion 530 contacts the blocking portion 120, thereby limiting the maximum stroke position of the damping device 500.

[0077] In this embodiment, the tail hook 310 and the second protruding portion 520 can make the damping device 500 produce buffering at the right time. The blocking portion 120 and the third protruding portion 530 cooperate to limit the return stroke of the damping device 500 and make it work within a predetermined range. At the same time, the blocking portion 120 plays a supporting role to prevent the damping device 500 from falling out of the hinge arm 100.

[0078] In an optional embodiment, the damping device 500 includes a sliding seat 540 and a buffer 550. The bottom of the sliding seat 540 is provided with a mounting groove 541 for placing the buffer 550, and the mounting groove 541 is provided with an opening near one end of the first connecting piece 200. The sliding seat 540 is the main bearing structure of the buffer 550, and the mounting groove 541 is matched with the buffer 550 and can accurately accommodate the buffer 550.

[0079] The buffer 550 is partially located in the mounting groove 541, and one end of the buffer 550 protrudes out of the opening and abuts against a predetermined position. Most of the buffer 550 is mounted in the mounting groove 541 of the sliding seat 540 and closely fits the inner wall of the groove, so that it does not deviate or loosen during work. The protruding part is used to abut against a predetermined position to form buffering when the damping device 500 works.

[0080] In this embodiment, through the adaptation of the sliding seat 540 and the buffer 550, as well as the design of the mounting groove 541 and the opening, the buffer 550 can play a buffering effect at the appropriate position, thereby improving the stability and durability of the damping device 500.

[0081] In an optional embodiment, a torsional spring 210 is provided at the hinge joint of the first connecting piece 200 and the hinge arm 100. The torsional spring 210 can effectively store and release energy, and assist the damping device 500 to achieve a soft damping effect.

[0082] The buffer 550 is in contact with the torsion spring 210 at one end of the opening. The buffer 550 is in contact with the torsion spring 210 at one end and in contact with the sliding seat 540 at the other end, thereby being compressed to generate a damping effect.

[0083] In this embodiment, the torsion spring 210 provides an elastic restoring force at the hinge joint of the first connecting member 200 and the hinge arm 100, and the contact of the buffer 550 with the torsion spring 210 enables the damping device 500 to more efficiently generate a buffering effect.

[0084] In an optional embodiment, a support part 110 is further included. The support part 110 is fixed to the top wall in the hinge arm 100. The bottom surface of the support part 110 is in close contact with the sliding seat 540. The bottom surface of the support part 110 and the mounting groove 541 of the sliding seat 540 together form a sliding channel for the buffer 550.

[0085] In this embodiment, the support part 110 enables the sliding seat 540 to slide in parallel and limits the position of the buffer 550 within a preset position.

[0086] Different from the above embodiments, as shown in FIG. 8, the cup-shaped concealed hinge can further include a damping switch 700.

[0087] The damping switch 700 is located on the opposite side of the damping adjustment device 600. The damping switch 700 is provided with a first column foot 710 and a second column foot 720. The first column foot 710 is used for insertion and fixation in the hinge arm 100.

[0088] The damping device 500 is provided with a limiting part 560 on the side close to the damping switch 700. The limiting part 560 and the second column foot 720 form a limiting effect.

[0089] When the damping switch 700 is closed, the second column foot 720 is on the same horizontal line as the limiting part 560. When the hinge is closed, the damping device 500 forcibly slides through the second column foot 720 with an inclination, so that the damping switch 700 is lifted to avoid the damping device 500, and the damping device 500 passes through. After the damping device 500 just passes through, because the damping switch 700 is an elastic member, the damping switch 700 immediately rebounds, so that the second column foot 720 is in contact with the limiting part 560 to prevent the damping device 500 from resetting. In this state, the damping device 500 no longer participates in the work, and the hinge changes from damping to non-damping. When the damping switch 700 is opened, the second column foot 720 avoids the limiting part 560, and does not affect the work of the damping device 500.

[0090] The working principle and working process of the cup-shaped concealed hinge of the embodiment are described as follows:

[0091] Adjusting process: as shown in FIGS. 15 and 16, the switch 621 is rotated by a certain angle, the rotating shaft 611 follows the rotation and drives the second rotating part 620 to rotate, under the condition that the second rotating part 620 rotates, the flange part 621 follows the rotation and abuts against the first protruding part 510, the flange part 621 extrudes the first protruding part 510, so that the damping device 500 changes the relative position of the hinge arm 100, and further changes the reset stroke of the damping device.

[0092] When the switch 621 is rotated back to the initial position, the abutting effect of the flange part 621 and the first protruding part 510 is weakened, and the damping device 500 returns to the original position through the stored energy of the buffer 560.

[0093] Door closing process: in some embodiments, the hinge cup 400 is fixed on the door plate, the hinge arm 100 is fixed to the inner side of the door cabinet, when the hinge cup 400 rotates to the closing direction to the adjusted damping angle, the hinge cup 400 is driven to rotate to the closing direction by the torsional force of the torsional spring 210, the first connecting part 200 and the second connecting part 300 are driven to rotate by the hinge cup 400, when the second connecting part 300 rotates to the closing direction with the hinge joint between the hinge arm 100 and the second connecting part 300 as the axis, the tail hook 310 on the second connecting part 300 hooks the second protruding part 520 arranged on the damping device 500, and drives the damping device 500 to move to the direction of the hinge joint between the hinge arm 100 and the second connecting part 300, at the same time, the buffer 550 installed in the mounting groove 541 of the sliding seat 540 abuts against the spring ring of the torsional spring 210, so that the resistance of the buffer 550 is transmitted to the inner side wall of the sliding seat 540 through the piston rod, thereby slowing down the moving speed of the damping device 500, and the slowed down moving speed of the damping device 500 slows down the rotating speed of the hinge cup 400 through the second connecting part 300, so that the door plate is slowly and gently closed, and the impact sound of the door plate and the door cabinet is eliminated.

[0094] Door opening process: when the hinge cup 400 rotates to the opening direction, the second connecting part 300 rotates to the opening direction with the hinge joint between the hinge arm 100 and the second connecting part 300 as the axis, the tail hook 310 on the second connecting part 300 moves away from the second protruding part 520 of the damping device 500, at the same time, the elastic force of the buffer 550 drives the piston rod to move out and drives the damping device 500 to move to the direction away from the hinge joint between the hinge arm 100 and the second connecting part 300, when the hinge cup 400 is fully opened, the hinge returns to the state before the closing action.
