Optionally, reinforcing ribs are provided on the sides of the second wedge 332 to increase the support strength of the second wedge 332 .

In this embodiment, the movable seat 333 can be made of POM material, thereby reducing the friction between the first wedge 312 and the second wedge 332 and reducing wear, so as to extend the life of the hinge assembly 30 service life. In other embodiments, the movable seat 333 can also be made of other materials, such as plastic. Therefore, any technical solution that is the same or similar to this embodiment is covered by the protection scope of the present invention.

In this embodiment, the second hinge structure 33 is installed on the box 10 , and the first hinge structure 31 is installed on the door 20 . During the closing process of the door body 20, the first hinge structure 31 rotates relative to the second hinge structure 33 until the first inclined surface 3121 abuts the third inclined surface 3321. When the door body 20 is closed, Under the action of force, the first wedge 312 in the first hinge structure 31 slides relative to the second wedge 332 along the third inclined surface 3321 through the first inclined surface 3121 until the first inclined surface 3121 and the third inclined surface 3121 are connected. The connection point of the two inclined planes 3122 moves to the plane 3323. If the door body 20 continues to be pushed, the door body 20 will move due to the gravity of the door body 20 and the sliding effect between the second inclined plane 3122 and the fourth inclined plane 3322. The door body 20 can realize automatic closing, that is, it can realize automatic closing when the door body 20 is closed to a certain angle.

And under the mutual resistance of the second inclined surface 3122 and the fourth inclined surface 3322, the door body 20 is closed more tightly, which can effectively solve the problem of the door body 20 not being closed tightly. It should be noted that the angle at which the door 20 automatically closes due to the interaction between the first wedge 312 and the second wedge 332 can be set as needed, such as 1 to 5 degrees.

In this embodiment, the slide groove 3111 includes a first groove 3112 that cooperates with the first shaft body 3311 and a second groove 3113 that cooperates with the second shaft body 3312. When the hinge assembly 30 is in the open position, During the closing process, the first shaft 3311 is in the first groove 3112, and the second shaft 3312 moves in the second groove 3113, so that the first shaft 3311 and the second shaft can 3312 can be adjusted and has high flexibility. Of course, in some embodiments, the first shaft 3311 and the second shaft 3312 can also move within a slide groove.

Further, the first groove 3112 is configured as a linear groove, and the second groove 3113 is configured as a curved groove. During the movement of the second shaft 3312 in the second groove 3113, the first shaft 3311 can reciprocate in the first groove 3112, and the second shaft 3312 can rotate around the The first shaft 3311 rotates, so that when the door 20 is opened, the door 20 can translate from the pivot side 12 of the box 10 to the storage room 11 side, thereby preventing the door 20 from being opened. Interference with surrounding cabinets or walls during opening.

Specifically, as shown in FIGS. 4 to 11 , the box 10 has a storage chamber 11 and a pivot side 12 connected to the hinge assembly 30 . The first slot 3112 includes an initial position L1 and a first stop position L2. The second slot 3113 includes a first end T1, a second end T2, and a third connecting end located between the first end T1 and the second end T2. One section S1 and the second section S2.
