Description

Technical Field

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

[0002] The cup-shaped concealed hinge is a hardware commonly used in modern furniture, designed specifically for connecting cabinet doors and cabinet bodies. It not only enables smooth opening and closing, but can also be hidden inside the cabinet door to maintain the simple appearance of the 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 result in the inability to optimize the buffering effect of the cabinet door at different opening and closing angles. And within the fixed buffering angle range, the damping device of the cup-shaped concealed hinge will be subjected to a higher frequency load, resulting in increased wear. At other angles, due to the lack of buffering, the cabinet door closes faster and with greater impact, which will also accelerate the wear of the overall structure.

It should be understood that these terms can be interchanged under appropriate circumstances, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here.

[0054] Next, exemplary embodiments according to the present application will be described in more detail with reference to the drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein.

[0055] As Figures 1 to 15 shown, the cup-shaped concealed hinge may include: a hinge arm 100, a connecting member, a hinge cup 400, a damping device 500, and an adjusting device 600. In some embodiments, it may further include a damping switch 700 and a disassembly bracket 800.

[0056] The connecting member is hinged between the hinge arm 100 and the hinge cup 400, and the connecting member 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 jointly hinged to the hinge cup 400 through a U-shaped pin 410. The hinge cup 400 can be fixed to the door / frame by bolts, etc., and the hinge arm 600 can be clamped and fixed to the base through the internally embedded disassembly bracket 800, and then fixed to the frame / door through the base.

[0057] The damping device 500 is slidably located within the hinge arm 100. The function of the damping device 500 is to effectively slow down the opening and closing speed of the cabinet door by slowly releasing the accumulated energy, provide a gentle closing experience, and prevent impacts and noises caused by slamming the door.

[0058] The adjusting device 600 is inserted through one side of the hinge arm 100. The adjusting device 600 is installed on one side wall of the hinge arm 100. The adjusting device 600 controls the reset stroke of the damping device 500 by changing the position of the damping device 500.

[0059] The end side of the second connecting member 300 is provided with a tail hook 310, which is used to rotate around the axis and contact 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. The interaction between the tail hook 310 and the damping device 500 generates a moderate damping force, so that the hinge can be gradually decelerated when closing.

[0060] The adjusting device 600 is used to adjust the maximum stroke position of the damping device 500 in the hinge arm 100 to adjust the maximum damping stroke, which refers to the maximum displacement distance at which the damping device can provide effective damping. The adjusting device 600 is used to adjust the maximum stroke position of the damping device 500 in the hinge arm 100, so that when the hinge is closed, the tail hook 310 and the damping device 500 collide at different angles to form a buffering effect.

[0061] In this embodiment, Figure 15 , 16 , from a state where no adjustment is performed ( Figure 15 ) to a state where a certain angle is adjusted by the adjusting device 600 ( Figure 16 ), the maximum stroke position of the damping device 500 in the hinge arm changes, and the hinge needs to rotate a larger angle to make the tail hook 310 collide with the damping device 500. Therefore, the maximum stroke position of the damping device 500 in the hinge arm 100 is adjusted by the adjusting device 600, and the maximum damping stroke is adjusted, the damping angle when the hinge is closed is changed, and the hinge closing time is changed, meeting the different needs of users for the closing time of the cabinet door. The damping angle refers to the angle at which the damping effect takes effect during a certain rotation or movement process.

[0062] In an optional embodiment, the adjustment device 600 includes 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 to the second rotating part 620. The rotating switch 612 can be provided with a cross groove for easy installation. The rotating shaft 611 can be a cylinder with a triangular or polygonal cross section, and the second rotating part 620 is provided with a socket adapted to 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 socket. The first rotating part 610 and the second rotating part 620 can also be fixedly connected by bolts or buckles.

[0063] The second rotating part 620 is provided with a flange part 621, and the damping device 500 is provided with a first protrusion part 510 that contacts the flange part 621. The flange part 621 may be a smooth curved surface structure, which can smoothly press other components when rotating.

[0064] The rotation switch 612 drives the second rotating part 620 to rotate through the rotating shaft 611. When the second rotating part 620 rotates to a preset angle, the flange part 621 squeezes the first protruding part 510 to change the position of the damping device 500 in the hinge arm 100. In actual operation, the user can rotate the rotation switch 612 to make the rotating shaft 611 drive the second rotating part 620 to rotate. 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 pressure. This pressure is transmitted to the damping device 500 through the first protruding part 510, so that the relative position of the damping device 500 inside the hinge arm 100 changes.

[0065] In an optional embodiment, through this adjustment method, the user can more accurately control the maximum stroke position of the damping device 500, thereby more accurately adjusting the maximum damping stroke, more accurately changing the damping angle when the hinge is closed, and then more accurately changing the hinge closing time, so as to accurately meet the user's different requirements for the cabinet door closing time.

[0066] In an optional embodiment, the second rotating portion 620 is a semicircular pancake-shaped structure with a portion thereof being cross-cut, and the flange portion 621 is located at an arc edge of the semicircular pancake-shaped structure.

[0067] In this embodiment, a portion of the semicircular pancake-shaped structure that is cross-cut can prevent the cross-cut portion from colliding with the first protrusion 510 in advance, and the flange portion 621 located at the arc edge of the semicircular pancake-shaped structure helps reduce friction with the first protrusion 510 during rotation.

[0068] In an optional embodiment, the outer edge of the flange portion 621 is partially elliptical, so that the flange portion 621 can evenly distribute pressure when in contact with the first protrusion 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 fixed gear.

[0069] In an optional embodiment, the second rotating portion 620 is an elliptical pie-shaped structure, and the flange portion 621 is located at an end structure corresponding to the long axis of the elliptical pie-shaped structure.

[0070] In an optional embodiment, a plurality of the damping scale lines 130 are located outside the hinge arm 100 and distributed around the rotation switch 612. The damping scale lines can be marked with different colors or lengths for quick identification by the user.

[0071] An arrow indicator is provided on one side edge of the rotary switch 612. The shape of the arrow can clearly point to the currently selected damping scale line 130.

[0072] Among them, when the arrow indicating mark points to different damping scale lines 130, it indicates the current damping effect of the damping device 500. The user can change the direction of the arrow by rotating the rotary switch 612, so as to more intuitively adjust the closing speed of the cabinet door.

[0073] In this embodiment, a plurality of damping scale lines 130 are evenly arranged on the outer surface of the hinge arm 100. These scale lines are distributed around the rotary switch 612 to form a precise scale disk. 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.

[0074] In an alternative embodiment, the damping device 500 is provided with: a second protrusion 520 is located on the side of the damping device 500 and is used for hooking with the tail hook 310. The second protrusion 520 is used for hooking with the tail hook. When the hinge rotates to a specific angle, the tail hook 310 will hook the second protrusion 520, thereby triggering the damping device 500 to generate a damping force.

[0075] The hinge arm 100 of the third protrusion 530 is provided with a blocking portion 120 that cooperates with the third protrusion 530 to limit the maximum stroke of the damping device 500. The blocking portion 120 can be a rivet located inside the hinge arm 100, and can also provide support for the damping device 500 in the hinge arm 100. When the damping device 500 moves inside the hinge arm 100, the third protrusion 530 contacts the blocking portion 120, thereby limiting the maximum stroke position of the damping device 500.

[0076] In this embodiment, the settings of the tail hook 310 and the second protrusion 520 can enable the damping device 500 to generate buffering at an appropriate time. The blocking portion 120 and the third protrusion 530 cooperate to limit the return stroke of the damping device 500 when it resets and make it work within a preset range. At the same time, the blocking portion 120 plays a supporting role to prevent the damping device 500 from falling off the hinge arm 100.

[0077] In an alternative embodiment, the damping device 500 includes a slide base 540 and a buffer 550. The bottom of the slide base 540 is provided with an installation groove 541 for placing the buffer 550, and an opening is provided at one end of the installation groove 541 close to the first connecting member 200. The slide base 540 is the main bearing structure of the buffer 550, and the installation groove 541 matches the buffer 550 and can accurately accommodate the buffer 550.

[0078] The buffer 550 is partially located in the mounting groove 541, and one end of the buffer 550 extends out of the opening and abuts against a predetermined position. Most of the buffer 550 is installed in the mounting groove 541 of the slide seat 540, and fits tightly against the inner wall of the groove so that it does not deviate or loosen during operation. The protruding portion is used to abut against the predetermined position to form a buffer when the damping device 500 is working.

[0079] In this embodiment, through the adaptation of the slide seat 540 and the buffer 550 , as well as the design of the mounting groove 541 and the opening, the buffer 550 can exert a buffering effect at an appropriate position, thereby improving the stability and durability of the damping device 500 .

[0080] In an optional embodiment, a torsion spring 210 is sleeved at the hinge of the first connecting member 200 and the hinge arm 100. The torsion spring 210 can effectively store and release energy, and assist the buffer device 500 to achieve a soft damping effect.

[0081] The end of the buffer 550 extending out of the opening contacts the torsion spring 210. The buffer 550 contacts the torsion spring 210 at one end and contacts the sliding seat 540 at the other end, thereby compressing the sliding seat 540 to produce a damping effect.

[0082] In this embodiment, the torsion spring 210 provides an elastic restoring force at the hinge between the first connecting member 200 and the hinge arm 100, and the interference between the buffer 550 and the torsion spring 210 enables the damping device 500 to produce a buffering effect more efficiently.

[0083] In an optional embodiment, a support portion 110 is further included. The support portion 110 is fixed to the top wall of the hinge arm 100. The bottom surface of the support portion 110 is in close contact with the damping device 500 for sliding. The convex portion on the bottom surface of the support portion 110 and the mounting groove 541 of the slide seat 540 together form a slideway for the buffer 550.

[0084] In this embodiment, the support portion 110 can make the slide seat 540 slide in parallel and limit the position of the buffer 550 to be within a preset position.

[0085] The difference from the above embodiment is that, Figure 8 As shown, the cup-shaped concealed hinge may further include a damping switch 700 .

[0086] The damping switch 700 is located at 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 to be inserted into the hinge arm 100 for fixing.

[0087] A limiting portion 560 is provided on one side of the damping device 500 close to the damping switch 700. The limiting portion 560 cooperates with the second column foot to form a limiting effect.

[0088] Wherein, when the damping switch 700 is closed, the second column foot 720 is on the same horizontal line as the limit part 560. When the hinge is closed, the damping device 500 will be driven to forcibly slide over the second column foot 720 with an inclination, so that the damping switch 700 is lifted up to avoid the position, allowing the damping device 500 to pass. When the damping device 500 just passes, since the damping switch 700 itself is an elastic member, the damping switch 700 will immediately rebound, so that the second column foot 720 conflicts with the limit 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 turned on, the second column foot 720 avoids the limit part 560 and does not affect the work of the damping device 500.

[0089] The working principle and working process of the cup-shaped concealed hinge of this embodiment are described below:

[0090] Adjustment process: Figure 15 , 16 As shown, by rotating the rotary switch 621 to a certain angle, the rotating shaft 611 follows the rotation and drives the second rotating part 620 to rotate. When the second rotating part 620 rotates, the flange part 621 follows the rotation and contacts the first protruding part 510. The flange part 621 squeezes the first protruding part 510, thereby changing the relative position of the damping device 500 to the hinge arm 100, thereby changing the reset stroke of the damping device.

[0091] When the rotary switch 621 is turned back to the starting position, the interference effect between the flange portion 621 and the first protrusion 510 is weakened, and the damping device 500 returns to its original position through the stored energy of the buffer 560 .

[0092] Closing process: In some embodiments, the hinge cup 400 is fixed on the door panel, and the hinge arm 100 is fixed on the inner side of the door cabinet. When the hinge cup 400 rotates towards the closing direction to the adjusted damping angle, the torsion of the torsion spring 210 drives the hinge cup 400 to rotate towards the closing direction. The hinge cup 400 drives the first connecting member 200 and the second connecting member 300 to rotate. When the second connecting member 300 rotates towards the closing direction with the hinge point between the hinge arm 100 and the second connecting member 300 as the axis, the tail hook 310 on the second connecting member 300 will hook the second protrusion 520 provided on the damping device 500 and drive the damping device 500 to move towards the hinge point between the hinge arm 100 and the second connecting member 300. At the same time, the buffer 550 installed in the installation groove 541 of the slide seat 540 abuts against the spring coil of the torsion spring 210, so that the resistance of the buffer 550 is transmitted to the inner side wall of the slide seat 540 through the piston rod, thereby slowing down the moving speed of the damping device 500. At the same time, the damping device 500 slows down the moving speed, which causes the rotating speed of the hinge cup 400 to slow down through the second connecting member 300, so that the door panel closes slowly and gently, eliminating the impact sound between the door panel and the door cabinet.

[0093] Opening process: When the hinge cup 400 rotates towards the opening direction, the second connecting member 300 rotates towards the opening direction with the hinge point between the hinge arm 100 and the second connecting member 300 as the axis. The tail hook 310 on the second connecting member 300 will leave the second protrusion 520 of the damping device 500. At the same time, the elastic force of the buffer 550 causes the piston rod to eject and drive the damping device 500 to move away from the hinge point between the hinge arm 100 and the second connecting member 300. When the hinge cup 400 finishes opening, the hinge returns to the state before the closing action.
