[0032] The utility model makes further specific description in combination with the drawings. A cup inner buffering hardware hinge, it includes hinge arm 1 and hinge cup 2, hinge arm 1 is connected with hinge cup 2 through upper connecting rod 3 and lower connecting rod 4 hinge connection, upper connecting rod 3 and lower connecting rod 4 swing relative to hinge arm 1 and hinge cup 2, realize the opening and closing of hinge, its characterized in that: hinge cup 2 is provided with guide slot 5, guide slot 5 is set up through the cup wall of hinge cup 2, slider 6 is slidably installed in guide slot 5, hinge cup 2 is also installed with buffer 7, buffer 7 is connected with slider 6, upper connecting rod 3 is provided with drive arm 31 towards one end of hinge cup 2, when hinge is closed to the set angle, drive arm 31 is in contact with slider 6, drive arm 31 pushes buffer 7 compression and generates door closing damping force through slider 6.

[0033] In one embodiment: the guide slot 5 is in communication with the cup bottom of hinge cup 2, and the bottom of the slider 6 is in pressure sliding on the cup bottom of the hinge cup 2.

[0034] In one embodiment: the tail of the slider 6 extends upwardly with a driving table 61, the driving table 61 is in contact with the driving arm 31 to push the movement thereof.

[0035] In one embodiment: the surface of the driving table 61 is covered with a mute rubber sleeve 62.

[0036] In one embodiment: the hinge cup 2 is further provided with a reset spring 71, the reset spring 71 is in pressure between the hinge cup 2 and the slider 6, and the reset spring 71 pushes the slider 6 to move in a reset direction.

[0037] In one embodiment: the driving arm 31 is further provided with a reset pressing arm 32 on both sides thereof, the reset pressing arm 32 is in contact with the slider 6 when the hinge is opened, and pushes the slider 6 to move in a reset direction.

[0038] In one embodiment: the hinge cup 2 is provided with a mounting groove 21, and the buffer 7 is buckledly mounted in the mounting groove 21.

[0039] In one embodiment: the slider 6 is provided with a guide block 63 on both sides of the head thereof, and the guide block 63 is made of rubber material.

[0040] In one embodiment: the hinge arm 1 and the lower connecting rod 4 are further provided with a reset leaf spring 8, and the reset leaf spring 8 pushes the hinge to always move in a closing direction.

[0041] In one embodiment: the lower connecting rod 4 is provided with an extrusion cam 9, and one supporting leg of the reset leaf spring 8 is in sliding on the surface of the extrusion cam 9.

[0042] Working principle: in this case, the hinge arm 1 is connected with the hinge cup 2 through the upper connecting rod 3 and the lower connecting rod 4. When the door body 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, and the action is transmitted to realize the opening and closing of the door body.

[0043] When the hinge is closed, the relative movement between the hinge arm 1 and the hinge cup 2 will drive the driving arm 31 to move through the connecting rod mechanism.

[0044] Among them, the hinge cup 2 is provided with a guide groove 5 penetrating the cup wall, and the sliding block 6 is slidingly installed in the guide groove 5. The sliding block 6 is connected with the hinge cup 2 through the buffer 7.

[0045] When the hinge is closed to a certain angle, the driving arm 31 on the hinge arm 1 contacts the sliding block 6, and the movement of the driving arm 31 pushes the sliding block 6 to slide along the guide groove 5. The sliding of the sliding block 6 further compresses the buffer 7, and the buffer 7 provides damping force, effectively reducing the speed of closing the door body, reducing the impact force and noise.

[0046] At the same time, the hinge cup 2 is also provided with a reset spring 71, which is pressed between the sliding block 6 and the hinge cup 2. When the hinge is transitioned from the closed state to the open state, the reset spring 71 pushes the sliding block 6 to reset to the initial position, ensuring that the buffer function can continue to be effective when closing the door next time. At the same time, the reset plate spring 8 on the lower connecting rod 4 provides auxiliary reset force, ensuring that the hinge always moves in the closing direction.

[0047] It should be noted that: the tail of the sliding block 6 is provided with a driving table 61, and the surface of the driving table 61 is covered with a silent rubber sleeve 62. The silent rubber sleeve 62 reduces friction noise when the driving arm 31 pushes the sliding block 6, improving user experience. The head of the sliding block 6 is also provided with guide blocks 63 made of rubber material, which are tightly matched with the guide groove 5, ensuring the stability and silent performance of the sliding block movement, and enhancing the durability.

[0048] Among them, the buffer 7 is buckledly installed in the installation groove 21 in the hinge cup 2. The buckle structure makes the buffer easy to install and disassemble, which is conducive to production and maintenance operation.

[0049] Compared with the traditional technology, the buffer 7 in this case is installed inside the hinge cup 2, which avoids the problem that the buffer is placed in the hinge arm in the prior art, resulting in a large volume of the hinge arm, making the hinge structure more compact and the appearance more simple and beautiful. At the same time, the buffer directly bears the pushing force of the driving arm 31 through the sliding block 6, realizing precise buffer damping effect, which can effectively reduce the impact force and noise when the door body is closed, so it can be widely used.

[0050] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
