Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to an adjustable torque hinge and cabinet assembly. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] In modern daily life, hinges are widely used in the connection and opening / closing mechanisms of various containers, furniture, and electronic devices. Traditional hinges cannot be adjusted for their torque, and the different weights of the doors they are used with result in varying opening and closing efficiencies, thus limiting their application range.

[0004] To address this, some manufacturers install an adjusting screw on the top wall of the hinge arm. The bottom of this screw abuts against the torsion arm of the hinge's torsion spring. When the adjusting screw is moved up or down, it compresses or releases the torsion arm of the torsion spring to adjust the torque. However, with this setup, because the adjusting screw is a long and thin strip, its contact area with the torsion arm is small. During the process of moving the adjusting screw up or down, it may disengage from the torsion arm, causing the torsion spring's torque adjustment to fail. Secondly, placing the adjusting screw on the top of the hinge arm affects the overall appearance of the hinge, especially if the screw's surface finish is poor, making the metallic texture of the screw appear abrupt and significantly reducing the overall aesthetic appeal. Utility Model Content

[0005] In order to overcome the defects mentioned above in the prior art, the present invention provides an adjustable torque hinge and cabinet assembly, which can solve the problems of torque adjustment failure and low overall aesthetics of the hinge mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] An adjustable torque hinge includes a hinge cup and a hinge arm, wherein a rocker arm assembly is provided between the hinge cup and the hinge arm to achieve hinged opening and closing, wherein:

[0008] The rocker arm assembly includes an outer rocker arm and an inner rocker arm. Both ends of the outer rocker arm and both ends of the inner rocker arm are respectively hinged to the hinge cup and the hinge arm. A torsion spring is provided at the hinge point between the outer rocker arm and the hinge arm. A first torsion arm and a second torsion arm extend from both ends of the torsion spring, respectively. The first torsion arm abuts against the inner side of the hinge arm, and the second torsion arm abuts against the inner side of the inner rocker arm.

[0009] The device also includes an adjustment assembly, which includes an adjustment knob that is rotatable and passes through the side of the hinge arm, and a transmission block that is driven and engaged with the adjustment knob and located inside the hinge arm. The first torsion arm abuts against the transmission block, and the transmission block has an abutment surface that abuts against the first torsion arm and is inclined. When the adjustment knob is rotated, the transmission block can be moved along the length direction of the hinge arm, and the first torsion arm can be compressed or released through the abutment surface to adjust the torsion spring torque.

[0010] Furthermore, the end of the first torsion arm is bent to form an inclined folded edge, which abuts against the contact surface.

[0011] Furthermore, the adjustment knob is provided with a spiral rib, and at least two protrusions are arranged at intervals along the length of the hinge arm on the transmission block. The rib passes through and is engaged between two adjacent protrusions to achieve transmission connection.

[0012] When the adjustment knob is rotated, the transmission block can be moved along the length direction of the hinge arm by the cooperation between the rib and the protrusion.

[0013] Furthermore, the transmission block includes a top plate and a first side plate disposed on one side of the top plate, and the protrusion is disposed on the outer side wall of the first side plate; one end of the top plate extends to have an extension plate for abutting against the first torsion arm.

[0014] Furthermore, the transmission block also includes a second side plate disposed on the other side of the top plate, wherein the outer side wall of the second side plate is fitted with the inner side wall of the hinge arm to achieve guidance.

[0015] Furthermore, a cross groove for engaging with a screwdriver is provided on the outer end face of the adjustment knob, and the raised rib is provided on the inner end face of the adjustment knob.

[0016] Furthermore, a first pin is provided on the inner rocker arm, and the second torsion arm abuts against the first pin.

[0017] Furthermore, one end of the outer rocker arm near the hinge arm is hinged to the hinge arm via a second pin, and the torsion spring is sleeved on the second pin; one end of the inner rocker arm near the hinge arm is hinged to the hinge arm via a third pin.

[0018] Furthermore, it also includes a pair of needles threaded on the hinge cup, the pair of needles including a first needle and a second needle, the end of the outer rocker arm near the hinge cup being hinged to the hinge cup via the first needle, and the end of the inner rocker arm near the hinge cup being hinged to the hinge cup via the second needle.

[0019] Additionally, a cabinet assembly is included, comprising a cabinet body, a cabinet door, and the aforementioned adjustable torque hinge, wherein the hinge cup is mounted on the cabinet door, and the hinge arm is mounted on the cabinet body.

[0020] In summary, this utility model provides an adjustable torque hinge and cabinet assembly. By setting a transmission block between the adjustment knob and the torsion spring, and having a contact surface on the transmission block that abuts against the torsion arm of the torsion spring, the torque can be adjusted by driving the contact surface to compress or release the torsion arm of the torsion spring. Compared with the traditional method of using an adjustment screw to abut against the torsion arm of the torsion spring, its transmission reliability is higher and the risk of torsion spring torque adjustment failure is reduced. In addition, by placing the adjustment knob on the side of the hinge arm, the impact on the overall aesthetics of the hinge is reduced, and the perceived quality of the product is enhanced.

[0028] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] See Figure 1-5 This utility model provides an adjustable torque hinge, including a hinge cup 1 and a hinge arm 2. A rocker arm assembly is provided between the hinge cup 1 and the hinge arm 2 to realize hinged opening and closing. The rocker arm assembly includes an outer rocker arm 3 and an inner rocker arm 4. Both ends of the outer rocker arm 3 and the two ends of the inner rocker arm 4 are respectively hinged to the hinge cup 1 and the hinge arm 2. A torsion spring 5 is provided at the hinge point between the outer rocker arm 3 and the hinge arm 2. A first torsion arm 501 and a second torsion arm 502 extend from both ends of the torsion spring 5, respectively. The first torsion arm 501 abuts against the inner side of the hinge arm 2, and the second torsion arm 502 abuts against the inner side of the inner rocker arm 4 to provide a closing force for the hinge.

[0032] The system also includes an adjustment assembly, which comprises an adjustment knob 6 that is rotatable and passes through the side of the hinge arm 2, and a transmission block 7 that is driven and engaged with the adjustment knob 6 and located inside the hinge arm 2. The first torsion arm 501 abuts against the transmission block 7, and the transmission block 7 has an abutment surface 7041 that abuts against the first torsion arm 501 and is inclined. Specifically, the adjustment knob 6 has a spiral rib 602, and the transmission block 7 has at least two protrusions 702 spaced apart along the length of the hinge arm 2. The rib 602 passes through and is engaged between two adjacent protrusions 702 to achieve a transmission connection. Thus, when the adjustment knob 6 is rotated, the engagement between the rib 602 and the protrusion 702 can drive the transmission block 7 to move left and right along the length of the hinge arm 2, thereby compressing or releasing the first torsion arm 501 through the abutment surface 7041 to adjust the torque of the torsion spring 5.

[0033] Therefore, by adjusting the torque of the torsion spring 5, the opening force of the cabinet door can be controlled. Increasing the torque of the torsion spring 5 increases the force required to open the cabinet door, making it suitable for heavier or larger cabinet doors. Conversely, decreasing the torque makes opening easier, making it suitable for lightweight doors or scenarios requiring less effort. At the same time, the torque of the torsion spring 5 directly affects the buffering effect during closing. A higher torque may increase the closing speed (if the buffer is not adjusted synchronously), while a lower torque results in slower closing. Combined with the buffer, this allows for a smooth closing.

[0034] Therefore, the adjustable torque hinge of this utility model, by setting a transmission block 7 between the adjustment knob 6 and the torsion spring 5, has an abutment surface 7041 on the transmission block 7 that abuts against the first torsion arm 501 of the torsion spring 5. The torque is adjusted by driving the abutment surface 7041 to compress or release the torsion arm of the torsion spring 5. Compared with the traditional method of using an adjustment screw to abut against the torsion arm of the torsion spring 5, its transmission reliability is higher and the risk of torque adjustment failure of the torsion spring 5 is reduced. In addition, by passing the adjustment knob 6 through the side of the hinge arm 2, the impact on the overall aesthetics of the hinge is reduced and the product's grade is improved.

[0035] See Figure 5 The end of the first torsion arm 501 is also bent to form an inclined folded edge 5011, and the folded edge 5011 abuts against the abutting surface 7041, thereby increasing the abutting contact area between the first torsion arm 501 and the transmission block 7, improving the transmission reliability between the two, and reducing the risk of torque adjustment failure of the torsion spring 5.

[0036] See Figure 2 The transmission block 7 has an inverted U-shaped structure and includes a top plate 701 and a first side plate 702 and a second side plate 703 respectively disposed on both sides of the top plate 701. The hinge arm 2 also has an inverted U-shaped structure and includes a top wall and a first side wall and a second side wall respectively disposed on both sides of the top wall. The transmission block 7 is disposed inside the hinge arm 2, with the top plate 701 opposite to the top wall, the first side plate 702 opposite to the first side wall, and the second side plate 703 opposite to the second side wall. A plurality of protrusions 7021 are disposed on the outer side wall of the first side plate 702 of the transmission block 7. A mounting hole 201 is provided on the first side wall of the hinge 2. The adjustment knob 6 is rotatably inserted through the mounting hole 201, and the inner end face of the adjustment knob 6 is provided with a protruding rib 602 that engages with a plurality of protrusions 7021. One end of the top plate 701 extends into an extension plate 704 for abutting against the first torsion arm 501. The bottom of the extension plate 704 is provided with the aforementioned abutment surface 7041. The outer side wall of the second side plate 703 fits against the inner side of the second side wall of the hinge arm 2 to achieve guidance, thereby improving the stability of the transmission block 7 moving along the length direction of the hinge arm 2.

[0037] In this embodiment, three protrusions 7021 are provided and are arranged sequentially at intervals along the length of the hinge arm 2 on the first side plate 702. Of course, in other embodiments, two or four protrusions 7021 may also be provided, and the specific number of protrusions 7021 is not limited here.

[0038] In addition, a cross groove 601 for cooperating with a screwdriver is provided on the outer end face of the adjustment knob 6, so that the user can turn the adjustment knob 6 with a screwdriver to adjust the torque of the torsion spring 5.

[0039] See Figure 4 The inner rocker arm 4 is fitted with a first pin 8, and the second torsion arm 502 abuts against the first pin 8. It also includes a second pin 9 and a third pin 10. The outer rocker arm 3 has a second hinge hole 302 at one end near the hinge arm 2, and the hinge arm 2 has a seventh hinge hole 202. The outer rocker arm 3 is hinged to the hinge arm 2 by the second pin 9 passing through both the second hinge hole 302 and the seventh hinge hole 202. The torsion spring 5 is sleeved on the second pin 9. Additionally, the inner rocker arm 4 has a fourth hinge hole 402 at one end near the hinge arm 2, and the hinge arm 2 has an eighth hinge hole 203. The inner rocker arm 4 is hinged to the hinge arm 2 by the third pin 10 passing through both the fourth hinge hole 402 and the eighth hinge hole 203.

[0040] Furthermore, it also includes a double needle 11 that passes through the hinge cup 1. The double needle 11 includes a first needle 1101 and a second needle 1102. The outer rocker arm 3 has a first hinge hole 301 at one end near the hinge cup 1. The hinge cup 1 has a fifth hinge hole 101. The first needle 1101 passes through the first hinge hole 301 and the fifth hinge hole 101 respectively to achieve hinge on the hinge cup 1. The inner rocker arm 4 has a third hinge hole 401 at one end near the hinge cup 1. The hinge cup 1 has a sixth hinge hole 102. The second needle 1102 passes through the third hinge hole 401 and the sixth hinge hole 102 respectively to achieve hinge on the hinge cup 1.

[0041] In addition, this utility model also includes a cabinet assembly, including a cabinet body, a cabinet door, and the aforementioned adjustable torque hinge, wherein the hinge cup 1 is installed on the cabinet door, and the hinge arm 2 is installed on the cabinet body.

[0042] In summary, this utility model provides an adjustable torque hinge and cabinet assembly. By setting a transmission block 7 between the adjustment knob 6 and the torsion spring 5, the transmission block 7 is provided with an abutment surface 7041 that abuts against the torsion arm of the torsion spring 5. The torque can be adjusted by driving the abutment surface 7041 to compress or release the torsion arm of the torsion spring 5. Compared with the traditional method of using an adjustment screw to abut against the torsion arm of the torsion spring 5, the transmission reliability is higher and the risk of torque adjustment failure of the torsion spring 5 is reduced. In addition, by placing the adjustment knob 6 through the side of the hinge arm 2, the impact on the overall aesthetics of the hinge is reduced, and the product's sense of quality is enhanced.
