In the process of rotating and opening the door body 200, the hinge assembly 300 synchronously drives the door body 200 to translate along a preset track, so that the track of the door body 200 in the opening process can be controlled.

Hereinafter, the refrigerator embedded in the cabinet 400 is specifically described by taking the storage device as an example, and only the cabinet 400 at the rotating end of the door 200 is shown, and in actual installation, the refrigerator is entirely embedded in the cabinet 400. Of course, it should be understood that the storage device is not limited to this, and the storage device is not necessarily a refrigerator, but may be other household devices such as a microwave oven, a wardrobe, and the like. Meanwhile, the article placing device is not necessarily embedded in the cabinet 400, and can be used independently or embedded in other external environment parts such as a wall body.

When the hinge assembly 300 is disposed on the left sides of the case 100 and the door 200, the rotating end refers to the left end of the door 200, the first direction F1 is a direction approaching the cabinet 400 on the left side to the left, the second direction F2 is a direction far away from the cabinet 400 on the left to the right, the third direction F3 is a direction approaching the case 100 backward, and the fourth direction F4 is a direction far away from the case 100 forward.

Referring to fig. 3, the hinge assembly 300 includes a first rotating shaft 31 and a first guiding groove 21, and a second rotating shaft 32 and a second guiding groove 22. In the present utility model, the door body 200 is driven to translate along the preset track in the rotation and opening process by the cooperation of the double shafts (the first rotating shaft 31 and the second rotating shaft 32) and the double grooves (the first guide groove 21 and the second guide groove 22), and compared with the single-shaft hinge, the present utility model does not need high installation precision, and can greatly reduce the design cost and the installation difficulty.

Specifically, one of the first rotating shaft 31 and the first guiding groove 21 is provided on the case 100, and the other is provided on the door 200; one of the second rotating shaft 32 and the second guiding groove 22 is disposed on the case 100, and the other is disposed on the door 200.

That is, the distribution of the rotating shaft and the guiding groove may include various situations, in the first example, the first rotating shaft 31 and the second rotating shaft 32 are located in the case 100, and the first guiding groove 21 and the second guiding groove 22 are located in the door 200; in the second example, the first rotating shaft 31 and the second rotating shaft 32 are located on the door body 200, and the first guide groove 21 and the second guide groove 22 are provided on the box body 100; in the third example, the first rotating shaft 31 and the second guiding groove 22 are provided on the case 100, and the first guiding groove 21 and the second rotating shaft 32 are provided on the door 200; in the fourth example, the first rotating shaft 31 and the second guide groove 22 are provided on the door body 200, and the second rotating shaft 32 and the first guide groove 21 are provided on the box body 100.

The specific structure of the rotating shaft and the guiding groove will be described herein by taking the first example as an example, that is, the first rotating shaft 31 and the second rotating shaft 32 are located in the case 100, and the first guiding groove 21 and the second guiding groove 22 are located in the door 200. Of course, this is not a limitation.

Specifically, the hinge assembly 300 includes a hinge plate 30 fixed to the case 100, and the first rotation shaft 31 and the second rotation shaft 32 are both fixed to the hinge plate 30 and protrude toward the door 200.

Further, during the process of opening the door body 200, the first shaft 31 reciprocates in the first guide groove 21, and the second shaft 32 moves unidirectionally in the second guide groove 22. Of course, this is not a limitation.

Further, before the door body 200 is rotated and opened to 90 °, the door body 200 is in a first translation stage, and the translation direction of the door body 200 in the first translation stage has direction components of a first direction F1 and a third direction F3; after the door body 200 is rotated to be opened to 90 °, the door body 200 is in a second translation stage, and the translation direction of the door body 200 in the second translation stage has direction components of the fourth direction F4 and the second direction F2. The opening degree of the opening side can be ensured, and a larger angle can be conveniently opened.

Before the door body 200 is opened to 90 °, the door body 200 moves in a direction approaching to the cabinet 400 and moves in a direction approaching to the box body 100, so that the door body 200 is far away from the opening side of the box body 100 along the first direction F1 as far as possible, the opening degree of the opening side is ensured, and the problem that drawers, racks and the like in the box body 100 cannot be opened due to interference of the door body 200 is avoided; meanwhile, the center of gravity of the door body 200 is close to the box body 100, the integrity of the door body 200 and the box body 100 is maintained, the door body 200 is prevented from toppling over, and meanwhile, the door body 200 moves backwards, so that the maximum opening angle of the subsequent door body 200 can be further increased.

Further, in the first translation stage of the door 200, the second rotating shaft 32 moves in the second guiding slot 22 along a straight line. The second rotating shaft 32 moves along a straight line, so that the rotation amount of the door body can be increased, and a larger angle can be opened.

In one embodiment, in the first translation stage, the second rotating shaft 32 moves linearly in the second guiding groove 22 and then moves along a curve, so that the length of the second guiding groove 22 along the thickness direction of the door body 200 can be reduced, which is beneficial to thinning the door body. Of course, not limited to this, in other embodiments, the second rotation shaft 32 can also be configured to move along a straight line during the first translation stage.

It is known that at the end of the first translation phase, the door 200 is rotated open to 90 °.

Specifically, when the door body 200 is in the first translation stage and the second rotation shaft 32 moves to an inflection point between the linear movement and the curved movement along the second guide groove 22, the door body 200 is rotated to be opened to 80 °. Of course, this is not a limitation.

Further, as shown in fig. 8, when the door 200 is rotated to be opened to 90 °, the front wall 25 of the door 200 is positioned at the same plane as the pivoting side wall of the cabinet 100, so that interference between the door 200 and the cabinet 400 can be prevented.

After the door 200 is opened to 90 °, the door 200 moves in a direction away from the cabinet 400 at the rotating end, and at the same time, the door 200 moves in a direction away from the cabinet 100, so that the distance between the door 200 and the cabinet 100 can be increased, interference between the front wall 25 of the door 200 and the front end of the cabinet 400 is avoided, and the maximum opening angle of the door 200 is further increased.

In one embodiment, after the door 200 is rotated open to the end of the second translation phase, the door 200 is opened to the maximum opening angle of 110 °. Of course, this is not a limitation.

Further, before the door 200 is rotated to be opened to the first translation stage, the preset track further includes a third translation stage, and when the door 200 is opened to the end of the third translation stage and the door 200 is rotated to be opened continuously, the door 200 is switched to the first translation stage. Of course, the present invention is not limited thereto, and in other embodiments, a translation stage for translating in other directions or an in-situ rotation stage may be added between the third translation stage and the first translation stage according to the requirement.

In the third translation stage, the translation direction of the door 200 has a direction component of the first direction F1 and the fourth direction F4. The door body 200 can be far away from the opening side of the box body 100 along the first direction F1 as far as possible, the opening degree of the opening side is ensured, and the problem that drawers, racks and the like in the box body 100 cannot be opened due to interference of the door body 200 is avoided; meanwhile, the door 200 moves away from the front side of the case 100, so that the distance between the second side edge 27 and the case 100 can be increased, and interference between the second side edge 27 and the case 100 can be avoided.

Specifically, when the door body 200 is rotated to be opened to 45 °, the door body 200 starts the third translation stage, and at the end of the third translation stage, the door body is opened to 70 °. Of course, this is not a limitation.

Further, in the third translation stage, the second rotation shaft 32 moves linearly along the second guide groove 22, so that the rotation opening amount of the door body 200 can be increased, and the protrusion amount of the first side edge protruding toward the cabinet 400 caused by the movement of the door body 200 in the first direction F1 toward the cabinet 400 at the rotation end can be offset to some extent.

Further, before the third translation stage, the door 200 further has a fourth translation stage, and the translation direction of the door 200 in the fourth translation stage has a direction component of the third direction F3 and the second direction F2; in the fourth stage of translation of the door 200, the second shaft 32 moves in the second guide groove 22 in a straight line. That is, the door 200 moves toward the cabinet 100 while the door 200 moves away from the cabinet 400 at the rotating end at the beginning of the translation stage in which the hinge assembly 300 drives the door 200 to translate along the preset trajectory. On the one hand, the door body 200 moves away from the cabinet 400 at the rotating end, the distance that the first side edge 26 protrudes out of the pivoting side wall of the cabinet 100 is greatly reduced, that is, the displacement of the door body 200 along the second direction F2 counteracts the protruding out of the cabinet 100 along the first direction F1 during the rotation of the door body 200, so as to avoid interference between the door body 200 and the peripheral cabinet 400 or wall during the opening process; on the other hand, the gravity center of the door body 200 is close to the case 100, so that the integrity of the door body 200 and the case 100 is maintained and the door body 200 is prevented from tilting; meanwhile, the door body 200 moves backward, so that the maximum opening angle of the subsequent door body 200 can be further increased.

Meanwhile, in the fourth translation stage, the second rotating shaft moves linearly, so that the rotation amount of the door body 200 can be increased, a larger angle can be opened, and the stability of the door body 200 in motion can be enhanced.

Specifically, at the end of the fourth translational stage, the door 200 is rotated open to 45 °.

It can be known that, in the process of rotating and opening the door body 200, the preset track for driving the door body 200 to be flat sequentially includes the fourth translation stage, the third translation stage, the first translation stage, and the second translation stage. In the initial stage of the translation stage, the door 200 is moved in the fourth translation stage in a direction away from the cabinet 400 at the rotating end, the distance that the first side edge 26 protrudes from the pivoting side wall of the cabinet 100 is greatly reduced, that is, the displacement of the door 200 along the second direction F2 counteracts the portion of the door 200 protruding from the cabinet 100 along the first direction F1 during the rotation process of the door 200, so as to avoid interference between the door 200 and the peripheral cabinet 400 or the wall during the opening process; in the middle stage of the translation stage, the door body 200 sequentially passes through the third translation stage and the first translation stage, and the door body 200 always moves towards the direction of the cabinet 400 at the rotating end, so that the door body 200 is kept away from the opening side of the cabinet 100 as far as possible along the first direction F1, the opening degree of the opening side is ensured, the problem that drawers, racks and the like in the cabinet 100 cannot be opened due to interference of the door body 200 is avoided, and it is known that the first side edge 26 rotates towards the direction away from the cabinet 400 in the middle stage of the rotation process of the door body 200, and therefore, the door body 200 moves towards the cabinet 400 for a certain distance to avoid interference with the cabinet 400; at the later stage of the translation stage, the door body 200 is in the second translation stage, and the door body 200 moves away from the cabinet 400 at the rotating end again, so that the maximum opening angle of the door body 200 can be increased, and the user can conveniently take and put the articles.

It will be appreciated that in the above translation stage, the door 200 synchronously has a rotation motion, so that the door 200 is rotated to open, thereby facilitating the user to take and put the articles.

Further, before the hinge assembly 300 drives the door body 200 to translate along a predetermined trajectory, the door body 200 is rotated in situ to be opened to a first opening angle. That is, before the translation stage, the door body 200 is rotated and opened, and there is a stage of in-situ rotation, at this time, the door body 200 only rotates without translating in other directions, so that it can be effectively avoided that the door body 200 cannot be opened normally due to displacement of the door body 200 in a certain direction, such as the door body 200 with a turnover beam.

In one embodiment, the first opening angle is 14 °. Of course, this is not a limitation.

Referring to fig. 4, when the door 200 is in the fourth translation stage, the third translation stage, and the first translation stage, and the second rotating shaft 32 moves linearly, the displacement deviation of the first side edge 26 in the first direction F1 and the second direction F2 is within 0.2 mm. Correspondingly, during the process of opening the door body 200 from 14 ° to 80 ° in a rotating manner, the displacement deviation of the first side edge 26 in the first direction F1 and the second direction F2 is within 0.2 mm. That is, the first side 26 moves almost in a straight line, does not protrude toward the cabinet 400 too much, and preferably controls the movement track of the first side 26, so that interference between the door 200 and the cabinet 400 can be prevented.

Next, the relationship between the structure of the hinge assembly 300 and the motion trajectory of the door body will be specifically described with reference to fig. 3 to 9.

Referring to fig. 4 to 5, when the door body 200 is rotated in place during the opening process, the first shaft 31 rotates only in the first guide groove 21, the second shaft 32 moves in the second guide groove 22 around the first shaft 31, and at this time, the second shaft 32 moves along the circular arc trace 61 toward the rear wall 23 and the second side edge 27 of the door body 200.

Wherein the arrow in fig. 5 indicates the moving direction of the second rotating shaft 32.

Specifically, the first guide groove 21 includes an initial position P0, and the second guide groove 22 includes an arc segment L1 centered on the initial position P0. When the door body 200 is in the in-situ rotation stage, the first shaft 31 is maintained at the initial position P0, and the second shaft 32 moves along the arc segment L1 in the second guide groove 22 along the arc track line 61.

The circular arc track line 61 includes a first end D21 and a second end D22 opposite to each other, and when the door 200 is in the closed state, the axis of the second rotating shaft 32 is located at the first end D21; the second shaft 32 moves from the first end D21 to the second end D22 along the circular arc trajectory 61 in the stage of rotating the door body 200 in place, and the door body 200 is switched to the fourth translation stage when the shaft center of the second shaft 32 moves to the second end D22 and the door body 200 continues to rotate and open.

The circular arc trajectory 61 refers to the trajectory of the axis center of the second rotating shaft 32 during the movement of the circular arc segment L1.

Referring to fig. 4 and 6, in the fourth translation stage of the door body 200, the first shaft 31 moves in a curved line in the first guide groove 21, the second shaft 32 moves in a straight line in the second guide groove 22, at this time, the first shaft 31 moves in a curved line toward the first side edge 26 and the front wall 25, and the second shaft 32 moves in a straight line along the first straight line trace 63 toward the rear wall 23 and the second side edge 27 of the door body 200.

Wherein the arrow in fig. 6 indicates the moving direction of the first rotation shaft 31.

Specifically, the first guide groove 21 includes a first position P1 located at an end of the initial position P0 near the first side edge 26, the second guide groove 22 includes a first straight line segment L2 communicating with the circular arc segment L1, the first straight line segment L2 extends obliquely toward the rear wall 23 of the door body 200 and the second side edge 27, and the first straight line segment L2 has a third position D27. When the door 200 is in the first translation stage, the first shaft 31 moves from the initial position P0 to the first position P1, and the second shaft 32 moves in the second guide groove 22 along the first straight line L2 along the first straight line path 63 until the axis of the second shaft 32 is located at the third position D27.

Referring to fig. 4, 7-8, the middle stage of the translation stage is shown, that is, the door body sequentially passes through the third translation stage, and the first translation stage is rotated and opened to 90 °. When the door body 200 is switched from the fourth translation stage to the third translation stage, the first rotating shaft 31 is reversed in the first guide groove 21, and when the door body 200 is in the middle stage of the translation stage, the first rotating shaft 31 moves in the first guide groove 21 in a same direction, and the second rotating shaft 32 moves in the second guide groove 22 in a straight line and then in a curved line.

Wherein the two arrows in fig. 7 respectively indicate the moving directions of the first rotating shaft 31 and the second rotating shaft 32. The arrow in fig. 8 indicates the moving direction of the second rotating shaft 32.

In one embodiment, during the third translation stage, the second rotating shaft moves linearly in the second guiding slot 22, and during the first translation stage, the second rotating shaft 32 moves linearly in the second guiding slot 22 and then moves in a curved line.

Specifically, in the third translation stage and the first translation stage, the direction in which the second rotation shaft 32 moves linearly is the same as the direction in which the second rotation shaft 32 moves linearly in the fourth translation stage, that is, in the first translation stage, the second rotation shaft 32 moves linearly along the first linear trace 63. Of course, this is not a limitation.

During the first translation phase, the second rotation shaft 32 moves along a curved trajectory that bends toward the rotation end surface 24 and the first side edge 26 when the second rotation shaft 32 moves in a curved manner.

Specifically, the first guide groove 21 includes a second position P2 located at an end of the initial position P0 away from the first side edge 26, the second guide groove 22 further includes a curved section L3 that communicates with an end of the first straight section L2 away from the circular arc section L1, and the curved section L3 is bent and extended toward the rotating end surface 24 and the first side edge 26, that is, the curved section L3 is bent and extended toward the rotating end surface 24 and a direction away from the second side edge. The first straight line segment L2 has a fourth position D26 located on the side of the third position D27 near the curved line segment L3, and a second boundary position D23 connected to the curved line segment L3. When the door 200 is in the third and first translation stages, the first rotating shaft 31 moves from the first position P1 to the second position P2 in the first guide groove 21, and the second rotating shaft 32 moves from the third position D27 to the second guide groove 22 along the first straight line segment L2 and the curved line segment L3 in sequence.

During the third translation stage of the door 200, when the first shaft 31 moves from the first position P1 to the initial position P0, the shaft center of the second shaft 32 moves from the third position D27 to the fourth position D26. At this time, the third translation stage is ended, and the door body 200 is rotated to be opened to 70 °.

During the first translation stage of the door body 200, when the first shaft 31 continues to move from the initial position P0 to the second position P2, and moves from the fourth position D26 to the second junction position D23 along the first linear trace 63, the shaft center of the first shaft 31 is located between the initial position P0 and the second position P2, and at this time, the opening angle of the door body 200 is 80 °; when the first shaft 31 moves to the second position P2, the shaft center of the second shaft 32 moves along the curved track line to an end of the curved segment L3 away from the first straight segment L2, and at this time, the third translation stage ends, and the door body 200 is rotated and opened to 90 °.

Further, referring to fig. 4, the track of the first side edge 26 is shown, and during the movement of the second rotating shaft 32 along the first straight line segment L2, the corresponding track segment L12 of the first side edge 26 is shown, where the displacement deviation of the first side edge 26 in the first direction F1 and the second direction F2 is within 0.2 mm. That is, the first side edge 26 moves almost linearly, does not protrude excessively toward the cabinet 400, and can avoid interference between the door 200 and the cabinet 400.

Further, along the direction away from the first straight line segment L2, the curved line segment L3 extends in a curved manner toward the direction of the rotating end surface 24 and the second side edge 27, and then extends in a curved manner toward the direction of the rotating end surface 24 and the first side edge 26. The included angle between the tangent line of the curve section L3 and the rotating end surface is increased and then decreased. In the initial stage of switching the second rotating shaft 32 from the first straight line segment L2 to the curved line segment L3, the included angle between the moving direction of the second rotating shaft 32 and the rotating end surface 24 is gradually increased, so that the blocking of the movement of the second rotating shaft 32 caused by the inflection point can be avoided, and the fluency of the door body 200 during the rotating and opening period is enhanced.

Specifically, when the door body 200 is rotated to be opened to 90 °, the front wall 25 of the door body 200 is positioned on the same plane as the pivoting side wall of the case 100. Of course, this is not a limitation.

The first linear trajectory 63 refers to a movement trajectory of the axis of the second rotating shaft 32 when the second rotating shaft 32 moves along the first linear line L2. The curved track line refers to a movement track of the axis of the second rotating shaft 32 when the second rotating shaft 32 moves in the curved section L3.

Referring to fig. 4 and 9, wherein the arrow in fig. 9 indicates the moving direction of the first shaft 31, when the door 200 is switched from the first translation stage to the second translation stage, the first shaft 31 is reversed again in the first guide slot 21, that is, the first shaft 31 moves from the second position P2 back toward the first position P1; when the door body 200 is in the second translation stage, the first rotating shaft 31 moves in a curved line in the first guide groove 21, and the second rotating shaft 32 moves in a straight line in the second guide groove 22. At this time, the second rotating shaft 32 moves linearly along the second linear trajectory 64 toward the rotating end surface 24 and the first side edge 26 of the door body 200. In the final opening stage of the door body 200, the stability of the movement of the door body 200 can be enhanced by the linear movement of the second rotation shaft 32, and at the same time, the large-angle rotation can be realized.

Specifically, the second guiding groove 22 further includes a second straight line segment L4 connected to an end of the curved line segment L3 away from the first straight line segment L2, and the second straight line segment L4 extends obliquely toward the rotating end surface 24 and the first side edge 26. When the door 200 is in the second translation stage, the first shaft 31 moves from the second position P2 to the first position P1 in the first guide groove 21, and the second shaft 32 moves linearly along the second linear path 64 in the second linear section L4.

It can be seen that the junction between the curved section L3 and the second straight section L4 is a first junction D24, and the first translation stage is ended when the door 200 is rotated and opened until the axis of the second rotating shaft 32 is located at the first junction D24.

Further, when the first rotating shaft 31 moves from the second position P2 to the first position P1 in the first guide groove 21 to the initial position P0, the second rotating shaft 32 moves to the end of the second straight line segment L4 away from the curved line segment L3, and at this time, the axis center of the second rotating shaft 32 is located at the end position D25 of the second straight line trace line 64, and the door body 200 is opened to the maximum opening angle 110 °. That is, when the door body 200 is in the closed state and when the door body 200 is opened to the maximum opening angle, the first rotation shaft 31 is positioned uniformly, and the length of the first guide groove 21 can be shortened, so that the thickness of the door body 200 can be reduced.

The second linear trajectory 64 refers to a movement trajectory of the axis of the second rotating shaft 32 when the second rotating shaft 32 moves in the second linear section L4.

Further, the first guide groove 21 extends obliquely from the second position P2 toward the first position P1 toward the first side edge 26. The door body 200 can translate along a preset track in the translation stage.

Further, as shown in fig. 4, in the process of driving the door body 200 to translate along the preset track by the hinge assembly 300, the first rotating shaft 31 is approximately elliptical arc protruding towards the direction away from the rotating end surface 24 relative to the driving track line 5 of the first guiding groove 21. It is known that the shape of the first guide groove 21 is adapted to the drive track line. Therefore, when the first rotating shaft 31 moves in the first guiding groove 21, it can move along a curve, and at the same time, the distance between the two ends of the first guiding groove 21 in the thickness direction of the door body 200 can be reduced, which is beneficial to the design of the thinned door body 200.

Specifically, referring to fig. 4 to 9, the driving track line 5 includes a first driving position D11, a second driving position D12 located at a side of the first driving position D11 near the first side edge 26, and a third driving position D13 located at a side of the first driving position D11 far from the first side edge 26, a first driving track section 51 is defined between the first driving position D11 and the second driving position D12, the driving track line 5 between the second driving position D12 and the third driving position D13 is a second driving track section 52, and the driving track line between the third driving position D13 and the first driving position D11 is a third driving track section 53. When the first shaft 31 is at the initial position P0, the shaft center of the first shaft 31 is located at the first driving position D11; the door body 200 is in a fourth stage of translation when the first shaft 31 moves from the initial position P0 to the first position P1, the shaft center of the first shaft 31 moves from the first driving position D11 along the first driving track section 51 to the second driving position D12, and when the first shaft 31 is located at the first position P1, the shaft center of the first shaft 31 is located at the second driving position D12. When the first shaft 31 moves from the first position P1 to the initial position P0, the door body 200 is in the third translation stage, and the shaft center of the first shaft 31 moves from the second driving position D12 to the first driving position D11 along the second driving track section 52. When the first shaft 31 moves from the initial position P0 to the second position P2, the door body 200 is in the first translation stage, the shaft center of the first shaft 31 moves from the first driving position D11 to the third driving position D13 along the second driving track section 52, and when the first shaft 31 is in the second position P2, the shaft center of the first shaft 31 is in the third driving position D13. When the first shaft 31 moves from the second position P2 to the initial position P0, the door body 200 is in the second translation stage, the shaft center of the first shaft 31 moves from the third driving position D13 to the first driving position D11 along the third driving track section 53, and when the first shaft 31 moves to the initial position P0, the shaft center of the first shaft 31 is reset to the first driving position D11.

As shown in fig. 4, the first end D21, the second end D22, the fourth position D26, and the end position D25 are the same distance from the first driving position D11, that is, are all on the same-diameter arc C1 centered on the first driving position D11.

In a specific embodiment, the distance between the axes of the first rotating shaft 31 and the second rotating shaft 32 is 15 mm-23 mm, so that the movement track between the first rotating shaft 31 and the second rotating shaft 32 can be ensured not to be crossed, and the stability and feasibility of the movement of the door body 200 are enhanced.

Further, when the door body 200 is in the closed state, the distance between the first rotating shaft 31 and the front wall 25 is smaller than the distance between the second rotating shaft 32 and the front wall 25, so that on one hand, smoothness of movement of the second rotating shaft 32 along the second guide groove 22 in the door opening rotation process can be enhanced, and damage caused by interference between the second rotating shaft 32 and the second guide groove 22 is avoided, and door opening is affected; meanwhile, the inclination angle between the subsequent first straight line segment L2 and the front wall 25 can be reduced, and the trend that the first straight line segment L2 extends along the length direction of the door body 200 is increased, which is beneficial to thinning the door body 200.

In summary, in the storage device according to the present utility model, the door 200 is moved in a direction approaching the cabinet 400 before the door 200 is opened to 90 ° and is moved in a direction approaching the cabinet 100, and at the same time, the door 200 is moved in a direction separating from the cabinet 400 at the rotating end and is moved in a direction separating from the cabinet 100 after the door 200 is opened to 90 °. The opening degree of the opening side can be ensured, and the problem that drawers, racks and the like in the box body 100 cannot be opened due to interference of the door body 200 is avoided; and, the maximum opening angle of the subsequent door body 200 can be further increased.
