Of course, in some embodiments, the rotating portion 21 and the bending portion 22 may be fixed in other manners, or even integrally formed.

Wherein the hinge area 211 is adapted to hinge with the hinge cup structure 1. In some embodiments, the hinge region 211 may wrap around the roller 2111 and the arc tab 2112, wherein the arc tab 2112 is an extension on both sides of the hinge region. As shown in fig. 8 to 9, the hinge cup structure 1 is provided with a hinge portion 17, and both sides of the hinge portion 17 are provided with first pin holes 172. The first shaft pin 171 passes through the first pin hole 172 and the drum 2111 to hinge the hinge area 211 and the hinge cup structure 1. Of course, in some embodiments, other configurations may be used to effect articulation.

The following describes the structure of the hinge cup structure 1.

In an alternative embodiment, the hinge cup structure 1 provides a pressing force for closing the door.

The hinge cup structure includes: hinge cup body 11 and torsion spring.

The hinge cup body 11 is provided with a groove 111, and the side wall of the groove 111 is respectively provided with a square hole 112 and a special-shaped hole 113 in sequence. The torsion spring comprises a torsion spring main body, and a claw and an extension part which are obtained by extending the torsion spring main body; the claw is fixed in the square hole 112, and the extension part passes through the special-shaped hole 113 and can be propped against one end of the connecting structure 2. When the included angle between the hinge cup structure 1 and the connecting structure 2 is in a first range, the extending part abuts against one end of the connecting structure 2, and generates acting force on the connecting structure 2. The torsion springs may be plural, for example, a first torsion spring 12 and a second torsion spring 13, and the first torsion spring 12 and the second torsion spring 13 are respectively located at two sides of the hinge cup body 11. Wherein the first torsion spring 12 is provided with a first pawl 121 and a first extension 122. The second torsion spring 13 is provided with a second pawl 131 and a second extension 132.

Based on the above structure, when the door is pushed to be closed to an angle of about 40-35 degrees, the first torsion spring 12 and the second torsion spring 13 press the connecting structure 2 by abutting the arc lug 2112, and the generated pressing force drives the door to rotate around the reel 2111 as the axis to close the door.

In an alternative embodiment, the hinge cup structure 1 provides a damping force that buffers rotational door closing penetrability forces.

The hinge cup structure includes: a hinge cup body 11 and a damping device 16. The hinge cup body 11 is provided with a recess 111. A damping device 16, said damping device 16 comprising a damper 162; the damper 162 is located in the groove 111, one end of the damper faces the inner wall of the groove 111, and the other end of the damper faces the connecting structure 2; wherein, when the included angle between the hinge cup structure 1 and the connecting structure 2 is in the second range, the ends of the damper 162 respectively abut against the inner wall of the groove 111 and the ends of the connecting structure and generate damping force. When the hinge region 211 of the connection structure 2 contacts one end of the damping device 16 during the door closing process, the damping force of the damping device 16 can buffer the rotational door closing penetrability force, so that the door is slowly and gently closed, and the noise generated by the door striking the door frame is eliminated.

In some embodiments, the damper 162 may include a cylinder and a damper rod, one end of the damper rod being abutted against the inner wall of the groove 111, and the other end of the damper rod being located within the cylinder. The outer wall of the bottom of the oil cylinder is an inclined plane. When the hinge area 211 of the connection structure 2 contacts the inclined surface of the oil cylinder, thrust is generated on the oil cylinder, so that the oil cylinder is triggered to generate a directional damping force, and the rotation speed of the connection structure 2 of the door is slowed down. It should be noted that, the inclined plane is provided with and helps the atress even, increases the life of attenuator, and then increases the life of device.

It should be noted that, in the hinge cup structure 1, a torsion spring or a damping device may be provided, or may be provided at the same time. When the door is simultaneously arranged, the door can be driven to rotate around the winding drum 2111 as the axis to close the door, and noise generated when the door impacts the door frame can be eliminated.

In an alternative embodiment, a switching function may also be provided, i.e. to fix the door in a specific state. The damping device 16 further comprises: a clamp 161 and a switch 163; wherein the press hoop 161 is fixed above the groove 111 and forms an accommodating space with the groove 111, the accommodating space being used for limiting the movable range of the damper 162; a clamping groove 1611 is formed on one side of the pressing hoop 161; the switch 163 is slidably disposed in the engagement slot 1611 and has a downward projection. Correspondingly, a protrusion 1621 is arranged on the outer wall of the damper 162; wherein the boss contacts the protrusion 1621 when the switch 163 is slid to the first position range, and the boss is separated from the protrusion 1621 when the switch is slid to the second position range.

When the switch 163 is slid to the first position range, the boss of the switch 163 prevents the damper 162 (cylinder) from being compressed by the interference protrusion 1621, and thus prevents the rotation of the connection structure 2, and thus the rotation of the door. When the switch 163 slides to the second position range, the boss below the switch 163 is separated from the boss 1621, and at this time, the damper 162 (cylinder) generates a damping force to slow down the rotation of the link structure 2, but does not prevent further rotation of the link structure 2, under the thrust of the hinge region 211 of the link structure 2.

In some embodiments, the bottom of the post is beveled. When the cylinder of the oil damper 162 approaches the damper 162, the protrusion 1621 breaks through the inclined surface to the back surface of the inclined surface and abuts against the back surface. At this time, the damper 162 does not generate a damping force when the angle within a certain range is opened and closed.

In an alternative embodiment, the hinge cup structure 1 further includes a torsion spring protection sleeve, and the torsion spring protection sleeve is sleeved on the torsion spring. The torsion spring protective sleeve may be provided in plurality, such as a first torsion spring protective sleeve 14 and a second torsion spring protective sleeve 15. The first torsion spring protection sleeve 14 is sleeved on the first torsion spring 12, and the second torsion spring protection sleeve 15 is sleeved on the second torsion spring 13. The torsion spring protective sleeve comprises two separated parts, wherein the first part is sleeved on the clamping jaw, and the second part is sleeved on the torsion spring main body and the extension part. The second part comprises a sleeve which is matched with one end of the torsion spring main body, and a shaft post is arranged in the middle of the sleeve and is inserted into a coil of the torsion spring main body.
