Hinges are common means for connecting two objects to each other so that they can be joined in a rotatable manner, and generally, such hinges consist of a hinge cup mounted to a cabinet door and a hinge arm assembly mounted to a cabinet body. The traditional hinge has no buffering force when being opened and closed, and the connection between the cabinet door and the cabinet body is easy to break. Later, a merchant designed a way to add a damper to the hinge so that the hinge had a preliminary damping force, referred to as a one-piece force damping hinge; the disadvantage of the one-section force buffering hinge is that when the cabinet door is opened to the end, the back swing can be generated repeatedly, and the connection between the cabinet door and the cabinet body is easy to break after long-term practicality.
For this reason, patent No. CN211081433U discloses a two-stage force buffering hinge, which comprises a hinge cup, a two-stage force buffering hinge seat, a main hinge arm, an auxiliary hinge arm and a torsion spring, wherein the torsion spring is arranged at a position where the main hinge arm is hinged with a main body arm of the two-stage force buffering hinge seat, a first spring arm of the torsion spring is abutted with the inner side of the main body arm, a second spring arm of the torsion spring is abutted with the inner side of the auxiliary hinge arm, and a limit groove is arranged on the inner side of the main hinge arm; when the hinge cup is opened to a maximum angle relative to the two-section force buffering hinge support, the first spring arm and the second spring arm of the torsion spring form a negative angle, and the limiting groove is hooked on the hinge shaft. Therefore, when the first spring arm and the second spring arm of the torsion spring form a negative angle, the cabinet door connected with the hinge cup is in a free moving state relative to the cabinet body connected with the two-section force buffering hinge seat, and the cabinet door can hover freely at the moment, so that the condition that the cabinet door swings back for many times when being opened to the end is avoided. In addition, when opening the cabinet door to the end, the spacing slot on this main arm of articulation can catch on the articulated shaft to can effectively avoid touching the cabinet door by mistake and lead to the condition emergence that the cabinet door kick-backs to close.
However, the following disadvantages still exist with the hinge structure described above: 1. the hinge cup can hover the cabinet door only when the hinge cup is opened to a larger angle relative to the two-section force buffering hinge seat, so that the cabinet door is inconvenient; 2. the main hinge arm is relatively complex in structure due to the fact that the limiting groove is formed in the main hinge arm, and production and manufacturing cost of the hinge are increased.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1 to 10, the present invention firstly provides a novel two-section force buffering hinge, which comprises a movable cup seat 1 and a connecting arm 2 hinged with each other for opening and closing by a rocker arm assembly, wherein the rocker arm assembly comprises an outer rocker arm 3 and an inner rocker arm 4, and both ends of the outer rocker arm 3 and both ends of the inner rocker arm 4 are hinged with the movable cup seat 1 and the connecting arm 2 respectively. Specifically, a double needle 7 is fixedly inserted on the movable cup holder 1, the double needle 7 comprises a first stitch 701 and a second stitch 702, one end of the outer rocker arm 3 is hinged on the movable cup holder 1 through the first stitch 701, and one end of the inner rocker arm 4 is hinged on the movable cup holder 1 through the second stitch 702; the other end of the outer rocker arm 3 is hinged to the connecting arm 2 via a third pin 13, and the other end of the inner rocker arm 4 is hinged to the connecting arm 2 via a second pin 12.
In this embodiment, the buffer hinge further comprises a cover plate 6 covering the connecting arm 2, and the cover plate 6 can shield the parts in the connecting arm 2, so that the whole structure of the buffer hinge is more concise and beautiful.
In addition, the torsion spring 5 is further included, the torsion spring 5 comprises a torsion spring body 501 sleeved on the third pin shaft 13, and a first torsion arm 502 and a second torsion arm 503 which are arranged at two ends of the torsion spring body 501, wherein the first torsion arm 502 is in contact with the inner side of the top of the connecting arm 2, and the second torsion arm 503 is in contact with the inner side of the inner rocker arm 4. Preferably, the inner side of the inner rocker arm 4 is penetrated with a first pin 11, and the second torsion arm 503 is abutted against the first pin 11.
Therefore, after the movable cup seat 1 is closed to a certain angle, the inner rocker arm 4 can be driven to swing through the elasticity of the torsion spring 5, so that the automatic closing of the movable cup seat 1 is realized.
Referring to fig. 4, a folded edge 5031 is disposed at an end of the second torsion arm 503 away from the torsion spring body 501, the folded edge 5031 is disposed obliquely toward a direction approaching the first torsion arm 502, and a connection point between the folded edge 5031 and the second torsion arm 503 forms an inflection point. Thus, when the movable cup holder 1 is completely closed (as shown in fig. 8), the first pin 11 on the inner rocker arm 4 abuts against the second torsion arm 503; then the movable cup holder 1 is opened to drive the inner rocker arm 4 to swing until the first pin 11 on the inner rocker arm 4 contacts the inflection point (as shown in fig. 9), and the inner rocker arm is in a critical state at the moment; then, the movable cup holder 1 is continuously opened to drive the first pin shaft 11 to pass through the inflection point and to be abutted against the folded edge 5031, at the moment, the folded edge 5031 and the first torsion arm 502 form a negative angle, and the torsion spring 5 does not generate a certain effective force on the rotation of the rocker arm assembly, the movable cup holder 1 and the four-bar mechanism formed by the connecting arm 2, so that a cabinet door connected with the movable cup holder 1 is in a free movable state relative to a cabinet body connected with the connecting arm 2, and at the moment, the cabinet door can hover freely; the door can then hover at any angle throughout the process of continuing to open the movable cup holder 1 to fully open (as shown in fig. 10).
Therefore, the two-section force buffering hinge can avoid the condition that the cabinet door swings back for many times after being opened to a larger angle, and can prevent destructive pulling force from being generated at the joint between the cabinet door and the cabinet body. Meanwhile, the folded edges 5031 are arranged on the second torsion arms 503, so that the torsion spring 5 can be in a negative angle state faster when the movable cup seat 1 is opened, and therefore the cabinet door can hover when the movable cup seat 1 is opened at a small angle (about 30-45 degrees), and the cabinet door is convenient.
In addition, since the connection between the flange 5031 and the second torsion arm 503 forms an inflection point, when the movable cup holder 1 is closed and the inner rocker arm 4 is driven to swing in a resetting manner, the inner rocker arm 4 needs to pass through the inflection point to be abutted against the second torsion arm 503. Therefore, the inflection point can form certain resistance to the reset swing of the inner rocker arm 4, and the situation that the cabinet door is rebound and closed due to the fact that the cabinet door is touched by mistake can be effectively avoided.
Therefore, compared with the traditional hinge, the two-section force buffering hinge disclosed by the invention has the advantages that a limiting hook groove is not required to be formed on the outer rocker arm 3, the hinge structure is greatly simplified, and the production and manufacturing cost is reduced.
Wherein an included angle a is formed between the folded edge 5031 and the second torsion arm 503, and a is more than or equal to 10 degrees and less than or equal to 25 degrees. In this embodiment, the included angle a is 14 °. Therefore, in the range of the included angle a, the cabinet door can hover randomly when the movable cup seat 1 can be opened at a small angle, and meanwhile, the inflection point cannot form larger resistance to the swing of the inner rocker arm 4, so that the opening or closing process of the movable cup seat 1 is smoother.
