Description

Technical Field

[0001] The invention relates to a hinge, in particular to an in-cup buffer hardware hinge. Background Art

[0002] Hinges are one of the important components widely used in furniture and home appliances. They are mainly used to achieve flexible connection and opening and closing movement between doors and cabinets. As people's requirements for the performance and aesthetics of home products continue to increase, hinges with buffering functions have gradually become the mainstream in the market. Buffering hinges can effectively reduce closing noise and improve user comfort by providing damping when closing the door.

[0003] At present, the common buffer hinges on the market mainly adopt the structural design of installing the buffer directly inside the hinge arm. Although this design can achieve the basic buffering function, it also has obvious defects, as shown below: 1. The hinge arm is bulky: As a core component that provides damping function, the buffer usually requires a certain length and volume. Integrating the buffer into the hinge arm will complicate the structure of the hinge arm and significantly increase its volume. This design not only restricts the overall lightweight design of the hinge, but may also increase material costs.

[0004] 2. Affecting the appearance: When the size of the hinge arm increases, it will directly affect the overall appearance of the hinge, especially in modern furniture that pursues a simple design style. The huge hinge arm appears bulky and uncoordinated, which conflicts with the overall home design.

[0005] 4. Limited functional stability: Due to the limited internal space of the hinge arm, the length and stroke of the buffer are constrained, making it difficult to fully exert its buffering function, resulting in insufficient damping effect or unstable performance.

[0006] Based on the above problems, the design of the existing buffer hinge has been difficult to meet the comprehensive needs of users for furniture hardware in terms of appearance, performance and ease of use. Therefore, it is necessary to make further improvements thereto. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a cup-buffered hardware hinge with a simple structure, easy use, improved buffer installation position and structural design to reduce the hinge arm volume, optimize the appearance design, and improve the stability of the buffering function and ease of maintenance.

[0008] The objective of the present invention is achieved in the following manner: a hardware hinge with a buffer in a cup, comprising a hinge arm and a hinge cup, wherein the hinge arm and the hinge cup are hingedly connected via an upper connecting rod and a lower connecting rod, wherein the upper connecting rod and the lower connecting rod swing relative to the hinge arm and the hinge cup to realize the opening and closing of the hinge, and wherein the hinge cup is provided with a guide groove, wherein the guide groove penetrates through the cup wall of the hinge cup, wherein a slider is slidably installed in the guide groove, wherein a buffer is also installed in the hinge cup, wherein the buffer is connected to the slider, wherein a driving arm is provided at one end of the upper connecting rod facing the hinge cup, wherein when the hinge is closed to a set angle, the driving arm contacts the slider, and the driving arm pushes the buffer to be compressed through the slider to generate a damping force for closing the door.

[0009] Furthermore, the guide groove is connected to the bottom of the hinge cup, and the bottom of the sliding block is pressed and slides on the bottom of the hinge cup.

[0010] Furthermore: a driving platform is extended upward from the tail of the sliding block, and the driving platform contacts the driving arm to drive it to move.

[0011] Furthermore: the surface of the driving platform is covered with a sound-proof rubber sleeve.

[0012] Furthermore, a return spring is also arranged in the hinge cup, the return spring presses between the hinge cup and the slider, and the return spring pushes the slider to move in the return direction.

[0013] Furthermore, reset pressing arms are arranged on both sides of the driving arm. When the hinge is opened, the reset pressing arms contact the slider to push the slider to move in the reset direction.

[0014] Furthermore: a mounting groove is arranged in the hinge cup, and the buffer is snap-fitted into the mounting groove.

[0015] Furthermore: guide blocks are arranged on both sides of the slider head, and the guide blocks are made of rubber material.

[0016] Furthermore: a reset leaf spring is arranged between the hinge arm and the lower connecting rod, and the reset leaf spring pushes the hinge to always move in the closing direction.

[0017] Furthermore: an extrusion cam is arranged on the lower connecting rod, and one of the supporting legs of the reset leaf spring slides on the surface of the extrusion cam.

[0018] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0019] 2. The buffer is designed to be installed inside the hinge cup instead of the traditional hinge arm, which successfully reduces the volume of the hinge arm. This structural layout avoids the problem of bloated hinge arm caused by the hinge arm accommodating the buffer, making the hinge as a whole lighter and more compact, which meets the design requirements of modern furniture hardware.

[0020] 3. By hiding the buffer inside the hinge cup, the invention makes the hinge arm shape more concise and smooth. Especially in modern furniture that pursues simple design, the hinge structure of the invention effectively avoids the problem of the hinge arm being too large to damage the overall beauty of the home.

[0021] 4. The buffer is installed inside the hinge cup. Through the direct cooperation between the slider and the driving arm, the compression stroke and the stability of the buffer's force are guaranteed. The buffering effect is more significant and reliable, effectively reducing the impact force and noise when the door is closed.

[0022] 5. The present invention successfully realizes the coordinated work of buffering function and reset function through the cooperation of slider, guide groove and driving arm. The driving arm pushes the buffer to compress and generate damping force through the slider, and the reset spring or reset pressure arm can quickly reset the slider when the door body is opened, so as to prepare for the next use.

[0023] 6. The buffer is installed in the mounting groove inside the hinge cup by snap-on, which is convenient for quick installation and removal. This design greatly reduces the complexity of production and maintenance, and improves the maintainability and service life of the hinge. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described in detail below with reference to the accompanying drawings. A cup-buffered hardware hinge includes a hinge arm 1 and a hinge cup 2, wherein the hinge arm 1 and the hinge cup 2 are hingedly connected via an upper connecting rod 3 and a lower connecting rod 4, wherein the upper connecting rod 3 and the lower connecting rod 4 swing relative to the hinge arm 1 and the hinge cup 2 to realize the opening and closing of the hinge, and is characterized in that: a guide groove 5 is provided in the hinge cup 2, wherein the guide groove 5 penetrates through the cup wall of the hinge cup 2, wherein a slider 6 is slidably installed in the guide groove 5, wherein a buffer 7 is also installed in the hinge cup 2, wherein the buffer 7 is connected to the slider 6, wherein a driving arm 31 is provided at one end of the upper connecting rod 3 facing the hinge cup 2, wherein when the hinge is closed to a set angle, the driving arm 31 contacts the slider 6, and the driving arm 31 compresses the buffer 7 through the slider 6 to generate a closing damping force.

[0032] In one embodiment, the guide groove 5 is connected to the bottom of the hinge cup 2 , and the bottom of the slider 6 is pressed and slides on the bottom of the hinge cup 2 .

[0033] In one embodiment, a driving platform 61 extends upward from the tail of the slider 6 , and the driving platform 61 contacts the driving arm 31 to drive the driving arm 31 to move.

[0034] In one embodiment, the surface of the driving platform 61 is covered with a sound-proof rubber sleeve 62 .

[0035] In one of the embodiments: a return spring 71 is further provided in the hinge cup 2. The return spring 71 presses between the hinge cup 2 and the slider 6. The return spring 71 pushes the slider 6 to move in the return direction.

[0036] In one embodiment, reset pressing arms 32 are provided on both sides of the driving arm 31. When the hinge is opened, the reset pressing arms 32 contact the slider 6 to push the slider 6 to move in the reset direction.

[0037] In one of the embodiments: a mounting groove 21 is provided in the hinge cup 2 , and the buffer 7 is snap-fitted into the mounting groove 21 .

[0038] In one embodiment, guide blocks 63 are arranged on both sides of the head of the slider 6, and the guide blocks 63 are made of rubber material.

[0039] In one of the embodiments: a return leaf spring 8 is further provided between the hinge arm 1 and the lower connecting rod 4, and the return leaf spring 8 pushes the hinge to always move in the closing direction.

[0040] In one of the embodiments: an extrusion cam 9 is provided on the lower connecting rod 4 , and one of the supporting legs of the reset leaf spring 8 is located on the surface of the extrusion cam 9 and slides.

[0041] Working principle: In this case, the hinge arm 1 is hingedly connected to the hinge cup 2 through the upper connecting rod 3 and the lower connecting rod 4. When the door is opened or closed, the upper connecting rod 3 and the lower connecting rod 4 swing relative to the hinge arm 1 and the hinge cup 2, transmitting the action to realize the opening and closing of the door.

[0042] When the hinge is closed, the relative movement between the hinge arm 1 and the hinge cup 2 drives the driving arm 31 to move through the connecting rod mechanism.

[0043] A guide groove 5 penetrating the cup wall is provided in the hinge cup 2, and a slider 6 is slidably installed in the guide groove 5. The slider 6 is connected to the hinge cup 2 via a buffer 7.

[0044] When the hinge is closed to a certain angle, the driving arm 31 on the hinge arm 1 contacts the slider 6, and the movement of the driving arm 31 pushes the slider 6 to slide along the guide groove 5. The sliding of the slider 6 further compresses the buffer 7, and the buffer 7 provides a damping force, effectively slowing down the closing speed of the door body, reducing the impact force and noise.

[0045] At the same time, a return spring 71 is also provided in the hinge cup 2, and the return spring 71 presses between the slider 6 and the hinge cup 2. When the hinge transitions from the closed state to the open state, the return spring 71 pushes the slider 6 to return to the initial position, ensuring that the buffer function can continue to be effective when the door is closed next time. At the same time, the return leaf spring 8 on the lower connecting rod 4 provides auxiliary return force to ensure that the hinge always moves in the closing direction.

[0046] It should be noted that: a driving platform 61 is provided at the tail of the slider 6, and the surface of the driving platform 61 is covered with a silent rubber sleeve 62. The silent rubber sleeve 62 reduces friction noise when the driving arm 31 pushes the slider 6, thereby improving the user experience. Guide blocks 63 made of rubber material are also provided on both sides of the head of the slider 6. The guide blocks 63 are closely matched with the guide groove 5 to ensure the stability and silent performance of the slider movement and enhance durability.

[0047] The buffer 7 is mounted in a snap-fit ​​manner in the mounting groove 21 in the hinge cup 2. The snap-fit ​​structure facilitates the installation and removal of the buffer, which is beneficial to production and maintenance operations.

[0048] Compared with the conventional technology, the buffer 7 in this case is installed inside the hinge cup 2, which avoids the problem of the existing technology that the buffer is placed inside the hinge arm, resulting in a large hinge arm, making the hinge structure more compact and the appearance more simple and beautiful. At the same time, the buffer directly bears the driving force of the driving arm 31 through the slider 6, achieving a precise buffering and damping effect, which can effectively reduce the impact force and noise when the door body is closed, so it can be widely promoted and used.

[0049] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
