Description

Technical Field

[0001] This utility model relates to a hinge, and more specifically, to a damping buffer hinge. Background Technology

[0002] Hinges are common components used to connect two objects so that they can rotate relative to each other. Generally, such hinges consist of a cup-shaped component (hinge cup) mounted on a cabinet door and a hinge body mounted on the cup-shaped component via a folded connecting rod component (or arm component). The hinge body is mounted on the inner wall of the frame of the furniture or other storage object. When the door is closed, the connecting rod component is embedded in the cup-shaped component.

[0003] Existing hinges typically place the damping mechanism on the hinge body, which also features a three-dimensional adjustment structure. This makes the hinge body structure complex, the product bulky, inconvenient to install, and unsightly. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a damping buffer hinge.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A damping buffer hinge includes a hinge body and a hinge cup. The hinge body includes an arm assembly, an outer hinge arm, and an inner hinge arm. One end of the inner hinge arm is connected to the hinge body via a first inner hinge shaft, and the other end is connected to the hinge cup via a second inner hinge shaft. One end of the outer hinge arm is connected to the hinge body via a first outer hinge shaft, and the other end is connected to the hinge cup via a second outer hinge shaft. A torsion spring is provided on the first outer hinge shaft. A damping buffer assembly is provided inside the hinge cup. The damping buffer assembly includes a buffer seat, a damper, and a buffer member. The damper is disposed on the buffer seat and cooperates with the buffer member. The buffer member is slidably disposed on the buffer seat and has a force-receiving part that cooperates with a pushing part of the outer hinge arm. The pushing part pushes the buffer member from a first position to a second position through the force-receiving part, while the damper slows down the movement of the buffer member.

[0007] The present invention further includes the following feature: the buffer seat has a sliding groove adapted to the buffer member, and the buffer member can move from a first position to a second position within the sliding groove.

[0008] The present invention further includes a buffer seat with mounting holes for installing a damper.

[0009] The present invention is further provided that: the number of mounting holes is two, which are located on both sides of the slide groove respectively.

[0010] The present invention further includes a buffer baffle that cooperates with the damper.

[0011] The present invention further comprises: both sides of the buffer are recessed inward to form a force-bearing part, and the end of the outer hinge arm protrudes outward to form a pushing part. The pushing part is arranged opposite to the force-bearing part, and the pushing part can enter the force-bearing part as the outer hinge arm rotates to push the buffer.

[0012] The present invention is further provided with a plurality of raised ribs on the side of the buffer member facing the slide groove, the raised ribs extending along the moving direction of the buffer member.

[0013] The present invention further includes the following features: the buffer is provided with a locking slider and a locking track for the locking slider to move; the hinge cup is provided with a locking groove; and the locking slider can slide into the locking groove through the locking track to lock the buffer at the second position.

[0014] The present invention further includes the following feature: the locking slider is provided with an elastic hook, and the locking slider is slidably placed in the locking track via the elastic hook.

[0015] The present invention further includes: the buffer seat has an avoidance sliding hole, and the locking groove of the hinge cup is located below the avoidance sliding hole. When the locking slider moves along the avoidance sliding hole to the corresponding position of the locking groove, the locking slider can slide into the locking groove through the locking track.

[0016] The beneficial effects of this utility model are as follows: This utility model sets the damping buffer component in the hinge cup, thereby simplifying the structure of the hinge body and making the hinge body more compact and easier to install. At the same time, when the hinge cup rotates and closes relative to the hinge body, the pushing part of the outer hinge arm will cooperate with the force-receiving part of the buffer. At this time, the pushing part pushes the buffer from the first position to the second position through the force-receiving part. At the same time, the damper will slow down the movement of the buffer, thereby slowing down the hinge closing speed and realizing the damping buffer effect. This utility model realizes the damping buffer effect of the hinge by setting the damper and buffer in the hinge cup. The structure is simple and easy to assemble. Attached Figure Description

[0030] The present invention provides a further detailed description of an embodiment of a damping buffer hinge with reference to the accompanying drawings.

[0031] from Figure 1 It is known that a damping buffer hinge includes a hinge body 1 and a hinge cup 2. Typically, the hinge body 1 is installed on the side wall of the cabinet, while the hinge cup 2 is installed on the cabinet door. When the cabinet door is closed relative to the cabinet body, the hinge cup 2 will rotate and close relative to the hinge body 1.

[0032] from Figure 2 It is known that the hinge body 1 includes an arm assembly 11, an outer hinge arm 12, and an inner hinge arm 13. One end of the inner hinge arm 13 is connected to the hinge body 1 via a first inner hinge shaft 14, and the other end is connected to the hinge cup 2 via a second inner hinge shaft 15. One end of the outer hinge arm 12 is connected to the hinge body 1 via a first outer hinge shaft 16, and the other end is connected to the hinge cup 2 via a second outer hinge shaft 17. A torsion spring 18 is provided on the first outer hinge shaft 16. One torsion bar of the torsion spring 18 abuts against the inner side of the outer hinge arm 12, and the other torsion bar abuts against one end of the first inner hinge shaft 14. In order to prevent the first inner hinge shaft 14 from wearing, a wear-resistant sleeve 19 can be provided at this end, so that the torsion bar of the torsion spring 18 abuts against the wear-resistant sleeve 19.

[0033] The hinge cup 2 is equipped with a damping buffer assembly 3, from which... Figures 3 to 7 It is understood that the damping buffer assembly 3 includes a buffer seat 31, a damper 32, and a buffer member 33; the damper 32 is disposed on the buffer seat 31 and cooperates with the buffer member 33. During the movement of the buffer member 33, the buffer member 33 will compress the telescopic shaft of the damper 32 to reduce its moving speed; the buffer member 33 is slidably disposed on the buffer seat 31, and the buffer member 33 is provided with a force-receiving part 331 that cooperates with the pushing part 121 of the outer hinge arm 12; wherein the force-receiving part 331 is formed by both sides of the buffer member 33 being recessed inward. Alternatively, the force-bearing part 331 can be formed by adding components or other methods. The end of the outer hinge arm 12 protrudes outward to form the pushing part 121. Similarly, the pushing part 121 can be formed by adding components or other methods. The pushing part 121 is arranged opposite to the force-bearing part 331. The pushing part 121 can enter the force-bearing part 331 as the outer hinge arm 12 rotates to push the buffer 33. The pushing part 121 and the force-bearing part 331 do not contact each other when the hinge just begins to close, so that the hinge can close quickly.

[0034] When the hinge enters the buffering phase, the pushing part 121 pushes the buffer member 33 from the first position to the second position through the force-receiving part 331, while the damper 32 slows down the movement of the buffer member 33. In this invention, the first position is the position of the outer hinge arm 12 on the buffer seat 31 before pushing the buffer member 33 to move; typically, the damper 32 is in a free state at this position. Figure 9 As shown; the second position is after the hinge is closed, the outer hinge arm 12 pushes the buffer 33 to move on the buffer seat 31 to the final position, and normally the damper 32 is in a compressed state at this position. Figure 10 As stated above.

[0035] The buffer seat 31 has a groove 311 adapted to the buffer member 33. The buffer member 33 can move back and forth from a first position to a second position within the groove 311. The groove 311 guides and limits the movement of the buffer member 33 during its movement between the first and second positions. Several ribs 332 are provided on the side of the buffer member 33 facing the groove 311. The ribs 332 extend along the moving direction of the buffer member 33. The ribs 332 enhance the overall strength of the buffer member 33 and reduce the contact area between the buffer member 33 and the groove 311, thereby reducing wear and noise caused by friction during the movement of the buffer member 33. The buffer seat 31 also has mounting holes 312 for installing the damper 32, facilitating its installation.

[0036] like Figure 4 and Figure 5 Depending on the required buffer resistance, one or two dampers 32 can be installed, meaning the number of mounting holes 312 can be one or two. When there is only one mounting hole, it can be located on one side of the slide groove 311; when there are two mounting holes 312, they are located on both sides of the slide groove 311.

[0037] The buffer 33 is provided with a buffer baffle 333 that cooperates with the damper 32. The two ends of the buffer baffle 333 extend outward and abut against the telescopic shaft of the corresponding damper 32, so that the damper 32 can be distributed on both sides of the buffer 33 to provide stable and reliable resistance. This layout is more reasonable and will not affect the cooperation between the buffer 33 and the outer hinge arm 12.

[0038] To enable both buffered and unbuffered modes for the hinge, a buffer switching structure is incorporated, allowing users to switch the hinge to either buffered or unbuffered mode as needed. The specific structure of the buffer switching structure is as follows: the buffer element 33 is equipped with a locking slider 4 and a locking track 334 for the movement of the locking slider 4. The locking slider 4 is equipped with an elastic hook 41. When the locking slider 4 is engaged, the elastic hook 41 presses into the locking track 334 and hooks the lower end face of the locking track 334, thereby assembling the locking slider 4 onto the locking track 334. This structure does not restrict the locking slider 4 from moving back and forth on the locking track 334, allowing the locking slider 4 to slide within the locking track 334 via the elastic hook 41. The hinge cup 2 is equipped with a locking groove 5 that mates with the locking slider 4. Figure 8 As shown.

[0039] When it is necessary to switch the hinge from the buffered mode to the unbuffered mode, manually operate the locking slider 4 to move the buffer 33 to the second position. At this time, the locking slider 4 is positioned opposite the locking groove 5, and the locking slider 4 can slide into the locking groove 5 through the locking track 334, locking the buffer 33 in the second position. Figure 11 and Figure 12 As described above, when it is necessary to switch the hinge from the unbuffered mode to the buffered mode, simply slide the locking slider 4 out of the locking groove 5 through the locking track 334. At this time, the buffer 33 moves from the second position to the first position under the action of the damper 32.

[0040] The buffer seat 31 has an avoidance sliding hole 313. The locking groove 5 of the hinge cup 2 is located below the avoidance sliding hole 313. When the locking slider 4 moves along the avoidance sliding hole 313 to the corresponding position of the locking groove 5, the locking slider 4 can slide into the locking groove 5 through the locking track 334 to avoid interference between the locking slider 4 and the buffer seat 31.

[0041] This invention incorporates a damping buffer component 3 in the hinge cup 2, thereby simplifying the structure of the hinge body 1, making the hinge body 1 more compact and easier to install. Simultaneously, when the hinge cup 2 rotates and closes relative to the hinge body 1, the pushing part 121 of the outer hinge arm 12 engages with the force-receiving part 331 of the buffer component 33. At this time, the pushing part 121 pushes the buffer component 33 from the first position to the second position through the force-receiving part 331. Simultaneously, the damper 32 slows down the movement of the buffer component 33, thereby slowing down the hinge closing speed and achieving a damping buffering effect. This invention achieves the damping buffering effect of the hinge by incorporating a damper 32 and a buffer component 33 in the hinge cup 2. The structure is simple and easy to assemble. Furthermore, the hinge also features a buffer conversion structure, allowing the user to switch the hinge to a buffered or unbuffered mode as needed. When switching the hinge from a buffered mode to an unbuffered mode, the locking slider 4 slides into the locking groove 5 through the locking track 334, locking the buffer component 33 in the second position. When it is necessary to switch the hinge from the unbuffered mode to the buffered mode, simply slide the locking slider 4 out of the locking groove 5 through the locking track 334. At this time, the buffer 33 moves from the second position to the first position under the action of the damper 32.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
