Description

Technical field:

[0001] The invention relates to the technical field of hinge research and development and design, and in particular to a buffer hinge used for furniture. Background technology:

[0002] Hinges are mainly installed on doors and windows, and more often on cabinets and furniture door panels. They are mainly divided into stainless steel hinges and iron hinges according to the material classification. In order to give people a better enjoyment, hydraulic hinges (also known as damping hinges) have appeared. Their characteristic is that they provide a buffering function when the cabinet door is closed, which minimizes the noise caused by the collision between the cabinet door and the cabinet body when it is closed.

[0003] In the conventional hinges, in order to further reduce the number of parts, the mainstream method currently on the market is to use the second linkage of the hinge to drive the movement of the damper in the damper bearing seat to overcome the resistance of the torsion spring. In the specific structure, the piston rod of the damper is generally abutted against the torsion spring. However, when this structure is in use, the damper or the piston rod abuts against the torsion spring, which causes friction when the torsion spring rotates, or there is a method of bending the top plate on the outer shell to achieve blocking. However, in actual use, the large force of the torsion spring and the damper will cause damage to the bent top plate, causing the top plate to abut against the torsion spring, thereby affecting its overall use. It cannot meet market demand and requires further research and development and improvement. Summary of the invention:

[0004] One of the objects of the present invention is to provide a hinge, in particular a buffer hinge with lower manufacturing cost.

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0030] Example 1: Reference Figure 1-10 :A cushioning hinge for furniture.

[0031] It includes a housing 4, a first rotating shaft 41, a U-shaped pin shaft 5, a hinge cup 2, and a first linking member 7, wherein one end of the first linking member 7 is rotatably mounted on the housing 4 through the first rotating shaft 41, and the other end of the first linking member 7 is rotatably connected to the hinge cup 2 through one axis of the U-shaped pin shaft 5, and the hinge cup 2 is fixed on the door panel;

[0032] A second rotating shaft 42, a torsion spring 8, and a second linking member 3 are provided, wherein one end of the second linking member 3 is rotatably installed in the housing 4 via the second rotating shaft 42, and the other end of the second linking member 3 is rotatably connected to the hinge cup 2 via the other axis of the U-shaped pin 5, the torsion spring 8 is sleeved on the first rotating shaft 41, the first torsion arm of the torsion spring 8 is fixed on the U-shaped pin 5, and the second torsion arm of the torsion spring is in contact with the first linking member 7 or the housing 4;

[0033] A buffer mechanism and a supporting structure are provided, wherein the buffer mechanism is placed between the supporting mechanism and the housing 4 and is driven by the supporting structure to move within the housing;

[0034] The supporting mechanism includes a damper bearing seat 1 as described in any of the above structures installed in a housing 4, and the damper bearing seat 1 is driven to move by a second linking member 3 through a transmission member;

[0035] The buffer mechanism includes a damper 6 installed in the damper cavity 16 of the damper bearing seat 1 , and the blocking rod 44 is installed on the first linking member 7 .

[0036] Preferably, the first linking member 7 is located on one side of the damper 6 and has an extension portion 71 bent toward the damper 6 , and the blocking rod 44 is disposed on the extension portion of the first linking member 7 .

[0037] Based on the present embodiment, the baffle rod 44 is installed at the position of the first connecting member 7. Relatively speaking, the length of the baffle rod 44 installed on the first connecting member 7 is significantly shorter than the length of the baffle rod 44 installed on the outer shell 4. Specifically, when the baffle rod 44 is shorter, the rear end seat of the damper 6 is almost completely in contact with the baffle rod 44. When the baffle rod 44 is longer, the rear end seat of the damper 6 is partially in contact with the baffle rod 44.

[0038] When the baffle rod is shorter, the force-bearing area of ​​the baffle rod 44 is larger. In reality, the retraction force of the damper 6 is very large. When the door panel is frequently opened and closed for a long time, the baffle rod 44 is not easy to bend or damaged. When the baffle rod is longer, the force-bearing area of ​​the baffle rod 44 is smaller, which is similar to the principle that when a stick is longer, it is easier to bend when squeezed in the middle, and when the stick is shorter, it is less likely to bend when squeezed in the middle.

[0039] Compared with the baffle rod arranged on the housing 4 and located between the torsion spring 8 and the damper 6, the buffering stroke of the damper can be increased, and a damper with a longer stroke can be selected.

[0040] Optionally, the blocking rod may be configured to be rotatably mounted on the first connecting member.

[0041] Preferably, the transmission member includes a second linking member 3 located on one side of the damper supporting seat 1 and a transmission tooth portion 31 is provided corresponding to the side linkage portion 13 thereof. Preferably, the transmission tooth portion 31 of the second linking member 3 extends from one side of the second linking member 3 body toward the damper supporting seat 1. When the second linking member 3 rotates, the transmission tooth portion 31 transmits the side linkage portion of the damper supporting seat 1 to cause the damper supporting seat 1 to move in the outer shell 4.

[0042] Preferably, an opening on one side opposite to the rear side plate 103 of the damper cavity 16 of the damper bearing seat 1 is arranged relative to the direction of the torsion spring, and the damper 6 is installed in the damper bearing seat 1 .

[0043] Preferably, a piston rod 61 is provided at one end of the damper 6 and an end surface 62 of the damper 6 is provided at the other end. The piston rod 61 of the damper 6 is provided relative to the torsion spring 8 or the rear side plate 103 of the damper bearing seat 1 .

[0044] Preferably, the damper 6 abuts against the stop rod 44 at the end face 62 on the other side of the piston rod 61 , and the stop rod 44 blocks the end face 62 of the damper 6 to increase the resistance of the torsion spring 8 to return to its original position.

[0045] Preferably, a limiting mechanism is provided on the outer shell 4 for limiting the damper bearing seat 1 from being separated from the outer shell, and the limiting mechanism includes a limiting rod 43 provided on the outer shell, and the damper bearing seat 1 is provided between the limiting rod 43 and the U-shaped side wall of the outer shell 4.

[0046] In this embodiment, the limiting rod 43 can be used to limit the overall movement of the damper bearing seat 1 within the housing 4 when the hinge cup 2 rotates, thereby preventing the damper bearing seat 1 from being separated from the housing 4.

[0047] When this embodiment is used, when the torsion spring is reset, the hinge cup rotates to drive the second link to rotate, and the transmission tooth portion of the second link drives the link of the damper bearing seat to move as a whole in the direction of the torsion spring, so that the damper abuts against the baffle rod and generates a reverse force that causes the damper's piston rod to contract and overcome the resistance of the torsion spring to reset, thereby achieving a buffering effect.

[0048] Embodiment 2: A damper bearing seat, comprising a bearing seat body 10, wherein the bearing seat body 10 is surrounded by a left side plate 101, a right side plate 102, a rear side plate 103 and a top side plate 104 to form a damper cavity 16 for accommodating the damper, the front portion of the bearing seat body 10 has a side linkage portion 13 protruding to both sides thereof, the top side plate 104 has an arc-shaped transition portion 11, one end of the arc-shaped transition portion 11 is connected to the left side plate 101, and the other end of the arc-shaped transition portion 11 is connected to the right side plate 102, the arc-shaped transition portion 11 of the top side plate 104 is provided with a planar sliding plane portion 12 in the middle position, and the sliding plane portion 12 is located at the parallel center portion of the left side plate 101 and the right side plate 102.

[0049] In this embodiment, a sliding plane portion 12 is provided so that the surface of the top side plate 104 will not be damaged during the movement of the whole and the movement is smoother, especially when in sliding contact with the limit rod 43. The small sliding plane portion provides a sliding surface and provides positive load for the entire tube of the damper, and the overall product stability and performance are more stable.

[0050] Preferably, the two sides of the sliding plane portion 12 are respectively connected to one side of the first arc portion 111 and the second arc portion 112 of the arc transition portion 11, and the other side of the first arc portion 111 and the second arc portion 112 of the arc transition portion 11 is connected to the corresponding left plate 101 and the right plate 102.

[0051] Preferably, the two sides of the support seat body 10 are respectively provided with a tube main portion 14 extending to the inner walls of the two side plates of its outer shell 4, and the tube main portions 14 on both sides are connected to the left side plate 101 and the right side plate 102 corresponding to the support seat body 10, so that when it is installed in the outer shell 4 and moves, there will be no swinging problem.

[0052] Preferably, the top side plate 104 is connected to one side of the side linkage part 13 and the other side of the side linkage part 13 is respectively connected to the corresponding left plate 101 and right plate 102, the side linkage parts 13 on both sides of the bearing seat body 10 protrude from one side of the bearing seat body 10 to its two sides, and the side linkage parts 13 protrude from the bearing seat body 10 to its two sides. The connection between the side linkage part 13 and the bearing seat body 10 has a penetrating hook part 130, and the hook part 130 is formed by punching and shearing the left plate 101 to the right plate 102, so that the transmission surface during the transmission process is a plane rather than an arc surface, and the stability is higher.

[0053] Preferably, reinforcing ribs 113 are provided on both sides of the arc-shaped transition portion of the top side plate 104, and the reinforcing ribs 113 are formed by stamping the top side plate 104 to the connection between the left plate 101 and the right plate 102. In the present structure, the reinforcing ribs 113 are stamped as a whole, so that when it is used in a conventional damper bearing seat, the overall strength is further guaranteed, and an arc-shaped recess for bearing the damper is formed.

[0054] Preferably, the top side of the rear side panel 103 is connected to the top side panel 104, and the bottom side of the rear side panel 103 protrudes downwardly from its bottom surface to form a lower protrusion 15, and the lower protrusion 15 protrudes 0.5-3mm toward the plane of the opening on the opposite side of the top side panel. In order to control the height of the overall rear side panel of the damper bearing seat during the production process and improve the tolerance of the product, a height value of a rear side panel reference is provided when it is suitable for automatic installation, thereby improving the overall identity of the parts and making the height of the parts more controllable during the bending process and the process of part identity, which is suitable for automated processing.

[0055] Preferably, the lower raised portion 15 has an arc-shaped recessed portion 151 at the center position, and the arc mouth of the arc-shaped recessed portion 151 is matched with the diameter of the piston rod 61 of the damper 6. Based on this embodiment, it is suitable for providing an installation guide for the piston rod 61 of the damper 6 during assembly, and is suitable for rapid and automated assembly of the damper 6.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
