Description

Technical Field

[0001] This utility model relates to the field of furniture hinge technology, and in particular to a novel damping hinge. Background Technology

[0002] A hinge is a mechanical device used to connect two relatively independent solids and allow them to rotate relative to each other. Hinges are very common furniture door connectors, utilizing the principle of movable hinges to allow the door to open or close around an axis. A hinge is mainly assembled from components such as a hinge cup, inner rocker arm, outer rocker arm, hinge body, triangular component, base, U-bolt, damping component, torsion spring, plastic tube, several connecting pins, and screws. Hydraulic hinges utilize the flow of high-density oil in hydraulic pipes to achieve a buffering effect, allowing the door to close gently even with force. During hinge assembly, the connections of each component need to be positioned to align the matching connecting holes and screw holes of the hinge body, hinge cup, base, inner strip assembly, inner rocker arm, and outer rocker arm. Then, the components are assembled into a single unit using rivets. Except for the damping component, the hinge body, combined with other components, forms the hinge body.

[0003] Chinese patent application CN103670105B discloses a hinge and a device for mounting a damper to the hinge. The device includes a hinge, a mounting bracket, a fixing assembly, and a damper. The hinge includes a hinge arm defining a chamber. The mounting bracket is mounted in the chamber of the hinge arm. The mounting bracket includes a pair of side plates and a recess connected between the side plates. A locking portion is provided on the opposing inner surfaces of the side plates. The recess includes a through hole, and a limiting protrusion is formed around the through hole. The damper includes a body and a piston rod. A recessed area is provided at the front end of the body, and a pair of abutment portions are provided at the rear end of the body. The fixing assembly connects to the mounting bracket and fixes it to the hinge arm. During installation, the piston rod passes through the through hole of the fixing frame, the limiting protrusion of the insert is embedded in the recessed area of ​​the body, and the body of the damper is pushed between the two side plates of the fixing frame, so that the abutting part of the body is locked against the locking part in the two side plates. Furthermore, invention patent CN110952854B discloses "An Optimized Damping Opening and Closing Structure for Furniture Hinges," which includes a hinge cup and a connecting arm that are hinged together by a hinge arm assembly. The hinge arm assembly includes at least an inner hinge arm, which is hinged to the hinge cup and the connecting arm, and has an extending actuating part. A damper is provided on the connecting arm, and the damper includes at least a cylinder with a groove. When the hinge cup is hinged relative to the connecting arm, the inner hinge arm acts on the groove of the cylinder through the actuating part. The cylinder slides and / or compresses on the connecting arm through the interaction of the groove and the actuating part, thereby achieving automatic reset of the damper and / or damping closure of the furniture hinge. However, the damping components of both types of hinges face the hinge cup, which makes the contact points between the damping components and other parts prone to wear. Furthermore, the transmission connection between the damping components and the hinge cup is not smooth enough, resulting in a less than smooth opening and closing motion.

[0004] Therefore, a damped hinge with smoother opening and closing is needed. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is to provide a novel damping hinge.

[0006] To address the aforementioned technical problems, this utility model provides a novel damping hinge, comprising a hinge body and a damping assembly disposed within the hinge body. The hinge body includes an arm and an inner rocker arm rotatably disposed within the arm. The damping assembly includes a damping element, a linkage element, and a sleeve. The hydraulic pipe of the damping element is disposed within the sleeve, which is fixedly disposed within the arm. The linkage element is slidably disposed within the sleeve, and it abuts against and is linked to the spindle of the damping element. The linkage element also engages and is linked to the inner rocker arm. When the hinge is closed, the inner rocker arm rotates and pulls the linkage element to compress the damping element, causing the hinge to close slowly under the resistance of the hydraulic pipe.

[0007] Furthermore, the inner rocker arm is provided with a first tooth, and the linkage is provided with a second tooth, the first tooth and the second tooth being engaged and connected.

[0008] Furthermore, the arm body is provided with a recess, and the side of the sleeve is provided with a mounting groove. The sleeve is fixedly installed in the arm body by the cooperation of the recess and the mounting groove. The sleeve is also provided with a slot to accommodate the hydraulic pipe, and the shape of the slot is adapted to the shape of the hydraulic pipe.

[0009] Furthermore, the mounting groove is a U-shaped groove surface, and the concave point is engaged with the bottom of the mounting groove.

[0010] Furthermore, the sleeve is also provided with a notch, the inner width of which is adapted to the outer width of the tail of the inner rocker arm, and snap-fit ​​grooves are provided on both sides of the notch, which are snapped onto the connecting pins of the arm body.

[0011] Furthermore, a slide rail is provided inside the sleeve, and the linkage is slidably disposed in the slide rail. The linkage is L-shaped, the second tooth is located on the long side of the linkage, the second tooth extends out of the slide rail, and the spindle abuts against the inner wall of the short side of the linkage.

[0012] Furthermore, the hinge body also includes a base, which is detachably disposed within the arm body. The base has a clearance portion that accommodates the portion of the linkage that extends out of the sleeve.

[0013] Furthermore, the hinge body also includes a hinge cup, an outer rocker arm, and a torsion spring that provides the hinge closing power. Both ends of the outer rocker arm and the inner rocker arm are rotatably connected to the hinge cup and the arm body, respectively. The torsion spring is sleeved at the connection between the outer rocker arm and the arm body.

[0014] Furthermore, the outer rocker arm and the inner rocker arm are rotatably connected to the hinge cup via U-shaped pins.

[0015] Furthermore, one end of the torsion spring abuts against the end of the arm body, and the other end abuts against the cross pin of the inner rocker arm.

[0016] Implementing the embodiments of this utility model has the following beneficial effects:

[0017] The damping component does not require mechanical connection with the arm body and inner rocker arm. Quick connection can be achieved by using the first tooth on the inner rocker arm and the second tooth of the linkage component, thereby reducing the number of hinge parts, thus reducing the assembly process and cost of the hinge.

[0018] The sleeve conceals the connection between the inner rocker arm and the damping assembly, making the hinge more aesthetically pleasing and preventing the linkage from dislodging, thereby improving the stability of the linkage.

[0019] A notch is drilled into the arm body, and the sleeve is slidably installed into the arm body through a "U"-shaped mounting groove. The notch is locked at the bottom of the mounting groove, ensuring precise installation of the sleeve. Attached Figure Description

[0028] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1-3 As shown, a novel damping hinge includes a hinge body and a damping component 1 disposed within the hinge body. The hinge body includes an arm 2, an inner rocker arm 3 rotatably disposed within the arm 2, a base 4, a hinge cup 5, an outer rocker arm 6, and a torsion spring 7 that provides the hinge closing power.

[0030] like Figure 4 and5 As shown, the damping assembly 1 includes a damping element 11, a linkage element 12, and a sleeve 13. The hydraulic pipe 111 of the damping element 11 is sleeved in the sleeve 13, and the sleeve 13 is fixedly installed in the arm body 2. The linkage element 12 is slidably installed in the sleeve 13. The spindle 112 of the damping element 11 abuts against the inner wall of the linkage element 12, so that the linkage element 12 and the spindle 112 abut and move together. The inner rocker arm 3 is provided with a first tooth 31, and the linkage element 12 is provided with a second tooth 121. The first tooth 31 and the second tooth 121 are meshed and connected. No mechanical connection is required between the damping component 1 and the arm body 2 and the inner rocker arm 3. A quick connection can be achieved by using the first tooth 31 on the inner rocker arm 3 and the second tooth 121 of the linkage 12, thereby reducing the number of hinge parts, thus reducing the assembly process and cost of the hinge. The linkage 12 meshes with the inner rocker arm 3. When the hinge is closed, the inner rocker arm 3 rotates and pulls the linkage 12 to compress the damping component 11, and the hinge closes slowly under the resistance of the hydraulic pipe 111.

[0031] like Figure 1 , 4 As shown in Figure 5, the arm body 2 has a recess 21, and the side of the sleeve 13 has a mounting groove 131. The sleeve 13 is fixedly installed inside the arm body 2 through the cooperation of the recess 21 and the mounting groove 131. The sleeve 13 hides the connection between the inner rocker arm 3 and the damping component 1, making the hinge more aesthetically pleasing and preventing the linkage 12 from dislodging, thereby improving the stability of the linkage 12. The sleeve 13 also has a groove 132 for accommodating the hydraulic pipe 111. The mounting groove 131 is a U-shaped groove, and the recess 21 is engaged with the bottom of the mounting groove 131. By inserting the recess 21 into the arm body 2, the sleeve 13 is slidably installed into the arm body 2 through the U-shaped mounting groove 131, with the recess 21 engaged with the bottom of the mounting groove 131, ensuring precise installation of the sleeve 13.

[0032] like Figure 6 As shown, the sleeve 13 is also provided with a notch 133. The inner width of the notch 133 is adapted to the outer width of the tail of the inner rocker arm 3. The notch 133 is provided with a snap-fit ​​groove 134 on both sides, which snaps onto the connecting pin 22 of the arm body 2. By snapping onto the connecting pin 22 with the snap-fit ​​groove 134, the connection between the sleeve 13 and the arm body 2 is more secure. The sleeve 13 is also provided with a slide rail 135. The linkage 12 is slidably disposed in the slide rail 135. The linkage 12 is "L" shaped. The second tooth 121 is located on the long side of the linkage 12 and extends out of the slide rail 135. The spindle 112 abuts against the inner wall of the short side of the linkage 12.

[0033] like Figure 6 and 7The base 4 is detachably mounted inside the arm body 2 by screws. The base 4 has a clearance part 41, which accommodates the part of the linkage 12 that extends out of the sleeve 13. The linkage 12 can slide back and forth without touching the base 4, reducing unnecessary friction between parts.

[0034] like Figure 3 and 7 As shown, both ends of the outer rocker arm 6 and the inner rocker arm 3 are rotatably connected to the hinge cup 5 and the arm body 2, respectively. A torsion spring 7 is fitted at the connection between the outer rocker arm 6 and the arm body 2. The outer rocker arm 6 and the inner rocker arm 3 are rotatably connected to the hinge cup 5 via U-shaped pins 8. One end of the torsion spring 7 abuts against the end of the arm body 2, and the other end abuts against the cross pin of the inner rocker arm 3. When the hinge is closed, the torsion spring 7 returns to its original deformation, generating elastic force that closes the hinge cup 5. The damping element 11 generates resistance, slowing down the closing speed of the hinge cup 5.

[0035] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
