As one arrangement, the shackle may include a root portion 81 and a hooking portion 82. The hooking portion 82 is connected to the root portion 81 and is bent toward the door rear wall 33 and the door side wall 32. The screw penetrates through the root connection part 81 and is connected with the door body 30 to strengthen the connection strength of the root connection part 81 and the door body 30, so that the hooking part 82 only deforms when the latch hook is separated from the stop part 403.
The first engaging portion provided on the hinge plate 40 at a side away from the first body side wall is a stopper portion 403, and a hooking gap 404 is formed on a side of the stopper portion 403 close to the case.

When the door 30 is closed from the open state, as shown in fig. 10 to 12, a closing force F is applied to the door 30 W At the closing force F W Under the action, the door body 30 is gradually closed; as the door body 30 is rotated to be closed, the free end of the hooking portion 82 gradually approaches the stop portion 403.
As shown in fig. 10, when the door 30 is closed to G B0 When the hooking portion 82 abuts against the stopper portion 403; then at the closing force F W Under the action of the door body 10, the stop portion 403 interacts with the hooking portion 82, the hooking portion 82 is elastically deformed, and the door closing force F is applied W The free end of the hooking portion 82 gradually enters the hooking gap 404 (the corresponding stopping portion 403 enters the hooking portion 82) under the combined action of the forces of the stopping portion 403.
As shown in fig. 11 to 12, when the door 30 is closed to G B1 When the door body 30 is closed, the elastic deformation amount of the hooking portion 82 reaches the maximum deformation amount. When the door 30 is closed to G B1 After that, the elastic energy stored by the deformation of the hooking part 82 in the earlier stage is released, under the combined action of the acting forces of the hooking part 82 and the stopping part 403, the hooking part 82 is restored to the loose state, and the hooking part 82 is driven to further enter the hooking gap 404, so that the door body 30 is quickly and automatically closed, the locking of the locking hook and the hinge plate 40 is realized, and the door is realizedLocking of the body 30 to the case 10; above, G B0 ＞G B1 。
As a settable way, G B0 Setting the value to be any one of 15-20 degrees and G B1 Setting the value to be any one of 3-8 degrees; the door body 30 is closed to G B1 After that, the door body 30 is automatically closed. The door body 30 is closed to G B1 The hooking portion 82 releases elastic energy at a later stage, and the force released by the hooking portion 82 at this stage is referred to as locking force F S Locking force F S Causing the door 30 to close in place.
In the closing process of the door body 30, the door closing force F W Continuing until the door body 30 is closed to G B1 After the door body 30 is rotated and closed until the elastic deformation of the hooking portion 82 is maximized, the door closing force F is removed W The door body 30 has an inertial force F G So that the door body 30 maintains the original moving tendency of closing.
In summary, the door 30 is formed by G B0 Closing to G B1 During the closing force F W Under the combined action of the stop part 403, the hooking part 82 is elastically deformed; when the door body 30 is closed to G B1 When the hooking portion 82 is elastically deformed, the maximum deformation of the door body 30 is reached; at the door body 30, G is used B1 In the process of closing, the elastic force of the hooking part 82 is released, and the locking force F S The elastic force of the hooking part 82 and the acting force and inertial force F of the stop part 403 G Under the combined action of the above, the door body 30 is automatically and rapidly closed.
In combination with the arrangement of the second groove bottom 52 in this embodiment, settable, G 0 ＜G B1 . Namely, the door body 30 is formed by G B1 In the process of closing, the door body 30 is automatically closed under the action of elastic potential energy released from the hooking portion 82 of the locking structure.
As the closing angle of the door body 30 decreases, the elastic potential energy of the hooking portion 82 decreases, which easily results in insufficient driving force of the door body 30 at the final stage of closing; the inclined second groove bottom 52 and the downward moving gap 3 are arranged to enable the closing angle of the door body 30 to be smaller than G 0 Has the characteristic of automatic closing to assist the closing of the door body 30, and ensures the existence of the door body 30Effectively closing. In summary, the second groove bottom 52 with the inclined surface and the downward moving gap 3 can assist in closing the door body 30, so that the door body 30 cannot be effectively closed due to insufficient elastic potential energy of the hooking portion 82 in the later closing stage of the door body 30, and the closing effectiveness of the door body 30 is ensured.

As another embodiment, the straight slot sections are parallel to the door front wall 31.
Wherein, the central track line of the first track groove 50 is marked as a first track line S, which is defined by the shape of the first track groove 50 and comprises a straight track section and a curve track section which are connected in a smooth transition way; the curved track segment is located on the side of the straight track segment adjacent the door sidewall 32 and is convex to the side adjacent the second side edge N. In this embodiment, the distance between the curved track section and the door side wall 32 gradually decreases in the direction from the door rear wall 33 to the door front wall 31, and the straight track section is parallel to the door front wall 31; the movement thereof will be described later taking this setting as an example. As a further alternative, the curved track section of the first track line S is arranged as a right circular arc.

Specifically, the first trajectory groove 50 is located at one side of the second trajectory groove 60 near the door front wall 31 and the door side wall 32; the hinge assembly having the above track features enables the door body 30 to move in an inward (near the second body side wall) direction by a distance while rotating, thereby compensating for the outward displacement of the first side edge W caused by the simple rotation of the door body 30, and limiting the first side edge W to exceed the reference plane M 0 Effectively avoiding interference with the cabinet when the door 30 is opened.
Since the first track groove 50 and the first driving shaft 41 and the second track groove 60 and the second driving shaft 42 are in a relative movement relationship, when the door body 30 is opened with the first track groove 50 and the second track groove 60 as stationary references, the first driving shaft 41 moves in the first track groove 50, and the second driving shaft 42 moves in the second track groove 60.

Since the first driving shaft 41 and the second driving shaft 42 are fixed to the hinge plate 40; the movement of the door 30 relative to the box 10 is equivalent to the relative movement of the two in the plane of the top wall of the box 10 (or in the plane parallel to the top wall of the box 10). In the plane of the top wall of the case 10, the movement of the axis line segment PQ relative to the track groove 5 provided on the door 30 is equivalent to the movement of the hinge plate 40 relative to the door 30, and is also equivalent to the movement of the case 10 relative to the door 30.
