a damper 110 is arranged outside the arc-shaped channel 101 on at least one side of the hinge base 10; as shown in fig. 7-8, the damper 110 includes a damper body 111, and an arc-shaped guide rail 112 for moving the end of the movable shaft 3 is disposed on one side of the damper body 111; a damping cavity is arranged in the damper body 111, two damping cylinder covers 113 which are arranged up and down are fixedly arranged in the damping cavity, and a damping rod 114 is arranged in the middle of each damping cylinder cover 113 in a sliding manner; a piston 115 is fixedly arranged on a damping rod 114 between the two damping cylinder heads 113, and the piston 115 divides a chamber between the two damping cylinder heads 113 into an upper first chamber 116 and a lower second chamber 117; the piston 115 is provided with a damping hole 118 which is communicated with a first chamber 116 and a second chamber 117;
a damping spring 119 is arranged between the top end of the damping rod 114 and the top wall of the damping cavity, a pressure plate 120 is fixedly arranged at the bottom end of the damping rod 114, and the pressure plate 120 is connected with the inner wall of the damping cavity in a sliding manner;
a connecting cavity 121 is arranged between the arc-shaped guide rail 112 and the damping cavity, a damping end block 122 which can seal the connecting cavity 121 and is of an arc-shaped structure is arranged in the arc-shaped guide rail 112, and the damping end block 122 is connected with the arc-shaped guide rail 112 in a sliding manner;

In the process of closing the door, the movable shaft 3 moves downwards along the arc-shaped channel 101, meanwhile, the movable shaft 3 also moves downwards along the arc-shaped guide rail 112, and when the movable shaft 3 moves downwards to a certain position, namely the door body closes to a certain angle, the movable shaft 3 presses the damping end block 122, so that the damping end block 122 moves downwards; the downward movement of damping end block 122 generates pressure on the hydraulic oil, which presses against pressure plate 120, causing damping rods 114 to move upward;
during the upward movement of the damping rod 114, on the one hand, the damping spring 119 generates a damping force; on the other hand, the piston 115 compresses the non-Newtonian fluid in the first chamber 116 upward.
non-Newtonian fluids are fluids that do not satisfy the experimental law of Newtonian viscosity, i.e., fluids in which the shear stress and the shear strain rate are not in a linear relationship, and when the non-Newtonian fluid is subjected to a small force or a small impact velocity, the overall characteristics of the non-Newtonian fluid are similar to those of a liquid, but when the non-Newtonian fluid is impacted by an abrupt change of energy, the non-Newtonian fluid rapidly changes into a tough jelly.
Therefore, when the piston 115 is pressed against the non-newtonian fluid in the first chamber 116 during the closing of the door body, the force is initially small, and the non-newtonian fluid exhibits fluid characteristics, which flow along the damping orifice 118 into the second chamber 117; when the piston 115 continues to press upwards, the non-newtonian fluid in the first chamber 116 is forced to increase, the viscous characteristic of the non-newtonian fluid gradually changes into jelly, and the non-newtonian fluid further difficultly falls along the damping hole 118, so that a damping force is provided for the upward movement of the damping rod 114, namely, the downward movement of the movable shaft 3 and the closing of the door body.
In addition, during the downward movement of the movable shaft 3, the compression spring 6 is pressed to generate an elastic force, and the elastic force also provides a damping force for the closing of the door body.
Therefore, when the door body is closed, the compression spring 6, the damping spring 119 in the damper 110 and the non-newtonian fluid in the first chamber 116 form multiple damping, thereby preventing the door body 01 from dropping rapidly.

When the door is closed, the hinge head 1 rotates anticlockwise around the hinge shaft 2 and simultaneously drives the movable shaft 3 to move downwards along the arc-shaped channel 101 on the hinge seat 10, the included angle between the hinge head 1 and the hinge seat 10 gradually becomes 180 degrees, the support plate 5 drives the upper spring seat 7 to move downwards, the compression spring 6 is pressed to generate elastic force, and the elastic force generates damping force for closing the door; simultaneously, the damping spring 119 and the non-Newtonian fluid in the first chamber 116 also generate a damping force; the existence of multiple damping force prevents the door body 01 from falling down rapidly, can reduce the damage to the cabinet body 02, and simultaneously reduces the noise.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the present invention, and it should be understood by those skilled in the art that various modifications and changes may be made without inventive efforts based on the technical solutions of the present invention.
