Among them, a torsion spring for automatically closing the power of the hinge cup is installed at the hinged part of the hinge seat and the hinge arm.

[0003] However, the two-stage force buffer hinges on the market have the following deficiencies in actual application. After the door panel is opened 90 degrees, the door panel rebounds due to the action of the torsion spring, resulting in an opening amplitude of less than 90 degrees after the door panel is opened, affecting the normal space for placing and taking items and being inconvenient to use.

[0017] The present utility model will be further described below with reference to the accompanying drawings.

[0018] According to the attached Figures 1 to 4As shown in the figure, the two-stage force buffer hinge with a stopping function of the present utility model includes a hinge cup 1 adaptively installed with a door panel, a hinge seat 2 adaptively installed with a cabinet body, and a hinge arm 3 hinged between the hinge cup 1 and the hinge seat 2. A torsion spring 4 is connected to the hinge point between the hinge arm 3 and the hinge seat 2. The hinge seat 2 is provided with a transmission group 5 for opening and closing the hinge cup 1. The swinging end and the connecting end of the transmission group 5 are respectively hinged to the hinge cup 1 and the hinge seat 2. Among them, a limiting component is provided between the transmission group 5 and the hinge arm 3 to prevent the opened door panel from rebounding. The limiting component includes a stopping convex edge 6 and a limiting connecting piece 7. The limiting connecting piece 7 is arranged at the connection between the transmission group 5 and the hinge cup 1. The stopping convex edge 6 is arranged at the swinging end of the hinge arm 3. When the door panel rebounds after being opened, the stopping convex edge 6 is in frictional connection with the limiting connecting piece 7.

[0019] In this way, by adding a limiting component and using the structural cooperation of the stopping convex edge 6 and the limiting connecting piece 7 of the limiting component with the transmission group 5 and the hinge arm 3, when the door panel rebounds after being opened, through the frictional connection between the stopping convex edge 6 and the limiting connecting piece 7, the hinge cup 1 is effectively stopped, realizing the addition of a stopping effect without increasing components, preventing the door panel from rebounding, ensuring a sufficient opening amplitude for convenient placing and taking, and ensuring the use quality of the product.

[0020] Referring to Figures 1 to 4 As shown in the figure, for further refinement, the stopping convex edge 6 is integrally formed on the swinging end of the hinge arm 3 and forms a clearance arc position 9 with the hinge arm 3 for completely separating from the limiting connecting piece 7 after the hinge cup 1 is completely opened.

[0021] Among them, the stopping convex edge 6 has a stopping arc surface 61 that is in frictional connection with the limiting connecting piece 7 when the hinge cup 1 rebounds to 90 degrees after being opened to generate a stopping force.

[0022] That is, when the door panel is opened and the hinge cup 1 is completely opened driven by the door panel, the stopping convex edge 6 moves to the clearance arc position 9 accordingly, so that the stopping convex edge 6 and the limiting connecting piece 7 are in a completely separated state. Subsequently, under the elastic action of the torsion spring 4, the hinge cup 1 drives the door panel to rebound. When the hinge cup 1 of this structure rebounds to 90 degrees, the stopping convex edge 6 swings with the hinge arm 3, so that the stopping arc surface 61 is in frictional connection with the limiting connecting piece 7, overcoming the elastic force, thereby blocking the swinging of the hinge arm 3 and further blocking the rebounding of the door panel to achieve the stopping effect.

[0023] Among them, the limiting connecting piece 7 is set as an elastic limiting piece for providing a closing assistance force to the hinge cup 1. The elastic reaction of the force applied when the elastic limiting piece performs the closing action of the hinge cup 1 acts on the stopping convex edge 6.

[0024] When the door panel is closed and the hinge cup 1 starts to close accordingly, under the action of the force applied when the stop convex edge 6 and the limiting connecting piece 7 act, due to the self-return characteristic of the limiting connecting piece 7, the stop convex edge 6 has a certain closing assisting force, which facilitates sliding away from the limiting connecting piece 7, and enables the hinge to continue to close smoothly under the elastic action of the torsion spring 4. It is convenient to operate and improves the use quality of the product.

[0025] Refer to Figures 1 to 4 As shown, the swinging ends of the hinge arm 3 and the transmission group 5 are respectively hinged to the hinge cup 1 through U-shaped pins, and the limiting connecting piece 7 is arranged on the swinging end of the transmission group 5 and sleeved on one end of the U-shaped pin. The structure is simple, the structural stability is strengthened, and the stop effect is increased without adding components, ensuring a sufficient opening amplitude for convenient placing and taking, and ensuring the use quality of the product.

[0026] In addition, the transmission group 5 includes a transmission arm 51 and a swinging block 52. The limiting connecting piece 7 is installed on the swinging end of the transmission arm 51. The swinging end of the transmission arm 51 is hinged to the hinge cup 1 through a U-shaped pin. The connecting end of the transmission arm 51 is connected to the hinge seat 2 and one side of the swinging end of the swinging block 52 through a positioning shaft and a connecting shaft. The positioning end of the swinging block 52 is connected to the hinge seat 2 through a fixed shaft.

[0027] Moreover, the other end of the swinging end of the swinging block 52 is connected with a buffer damper 8, and the cylinder body of the buffer damper 8 is installed on the hinge seat 2.

[0028] Adopting the structural cooperation of the transmission group 5 and the buffer damper 8 of this structure improves the transmission stability of the structure, enables this structure to have a two-stage force buffering effect, ensures that the product closes automatically slowly, and reduces the generation of noise.

[0029] The above specific embodiments are only the specific embodiments with better effects of the present invention. Any structure identical or equivalent to the two-stage force buffering hinge with a stop function of the present invention is within the protection scope of the present invention.
