When the second upper rotating hole is located in the mounting part, the second upper rotating shaft can be detached from the opening, so that when the first upper hinge needs to be installed, the second upper rotating hole can be sleeved on the mounting part first, and then moved from the mounting part to the second rotating part, so that the installation convenience of the first upper hinge is improved. When the first upper hinge needs to be disassembled, the first upper hinge is moved from the second rotating part to the mounting part, and then disassembled from the mounting part. In this way, not only the installation convenience of the first upper hinge and the second upper rotating shaft is improved, but also the installation of the first upper hinge and the second upper rotating shaft after installation is more stable and not easy to fall off. Moreover, the first upper hinge and the second upper rotating shaft of the embodiment of the present disclosure do not need to be rotated, and can be installed by a mechanical arm, which improves the installation convenience and production efficiency.

[0084] Optionally, the second upper rotating shaft extends in the vertical direction, the mounting portion is communicated with the second rotating portion, and the mounting portion is located above and / or below the second rotating portion.

[0085] In the disclosed embodiment, the second upper rotating shaft extends in the vertical direction, and the mounting portion and the second rotating portion are arranged in the vertical direction, so that the second upper rotating hole can move between the mounting portion and the second rotating portion.

[0086] Optionally, the second upper rotating shaft includes a free end and a connecting end that are relatively arranged, the connecting end is connected to one of the door body 60 and the box body 50, and when the second rotating part and the mounting part are arranged in the direction from the free end to the connecting end, the height of the mounting part is greater than or equal to the height of the second upper rotating hole.

[0087] In the disclosed embodiment, it can be understood that the connecting end of the second upper rotating shaft is used to be fixedly connected to the box body 50 or the door body 60, and the free end of the second upper rotating shaft is used to cooperate with the box body 50 to achieve rotation. When the second rotating part and the mounting part are arranged in the direction from the free end to the connecting end, since the mounting part is closer to the connecting end, the height of the mounting part is less than the height of the second upper rotating hole, which will cause the second upper rotating hole to be unable to move completely to the outside of the mounting part, thereby causing the first upper hinge to be unable to disengage from the second upper rotating shaft. Therefore, the height of the mounting part is greater than or equal to the height of the second upper rotating hole, which can ensure that the first upper hinge can be smoothly disengaged.

[0088] For example, when the free end of the second upper rotating shaft faces upward and the mounting portion is located below the second rotating portion, the height of the mounting portion is greater than or equal to the height of the second upper rotating hole.

[0089] Optionally, when the mounting portion and the second rotating portion are arranged along the direction from the free end to the connecting end, the height of the mounting portion can be less than, equal to or greater than the height of the second upper rotating hole. Since the mounting portion is close to the free end and there are no other components at the free end, the first upper hinge and the second upper rotating axis can be disengaged even if the height of the mounting portion is less than the height of the second upper rotating hole.

[0090] Optionally, the cross section of the second rotating portion is circular, and the width of the cross section of the mounting portion is smaller than the diameter of the second rotating portion.

[0091] In the disclosed embodiment, the cross section of the second rotating part is circular, so that the second upper rotating hole can rotate around the second upper rotating shaft. The width of the cross section of the mounting part is smaller than the diameter of the second rotating part, so that when the second upper rotating hole is sleeved on the outside of the second rotating part, the second upper rotating hole cannot be separated from the second rotating part, and when the second upper rotating hole is sleeved on the outside of the mounting part, since the width of the cross section of the mounting part is smaller than the diameter of the second rotating part, the mounting part can be separated from the opening of the mounting part, thereby realizing the installation and disassembly of the first upper hinge and the second upper rotating shaft.

[0092] It should be noted that the cross section of the second rotating portion refers to a cross section perpendicular to the axial direction of the second upper rotating shaft, and the cross section of the mounting portion refers to a cross section perpendicular to the axial direction of the second upper rotating shaft.

[0093] Optionally, the mounting portion includes an arcuate edge and a straight edge, wherein there are two arcuate edges, which are arranged opposite to each other along the radial direction of the second upper rotating shaft and are smoothly connected to the outer wall surface of the second rotating portion; the straight edge is connected between the two arcuate edges, wherein there are two straight edges, which are arranged opposite to each other; wherein, along the radial direction of the second upper rotating shaft, the distance between the two straight edges is smaller than the distance between the two arcuate edges, and the width of the cross section of the mounting portion is the distance between the two straight edges.

[0094] In the disclosed embodiment, the provision of the arc-shaped edge facilitates the smooth transition of the second upper rotating hole from the second rotating portion to the mounting portion, and the provision of the two right-angled edges reduces the width of the cross section of the mounting portion, so that after the second upper rotating hole moves to the mounting portion, it can move along the two right-angled edges, thereby realizing the separation of the second upper rotating hole from the second upper rotating shaft. Similarly, during installation, the second upper rotating hole first moves along the right-angled edges so that the second upper rotating hole is sleeved on the outside of the second upper rotating shaft, and then moves from the mounting portion to the second rotating portion, and then realizes the rotation of the second upper rotating hole relative to the second upper rotating shaft.

[0095] Optionally, the minimum distance between the two open ends of the second upper rotating hole is smaller than the diameter of the second rotating portion, and is greater than or equal to the width of the cross section of the mounting portion.

[0096] In the disclosed embodiment, the minimum distance between the two ends of the opening of the second upper rotating hole is smaller than the diameter of the second rotating portion, so that when the second upper rotating hole is in the second rotating portion, the second upper rotating shaft will not be separated from the second upper rotating hole, thereby improving the connection stability. The minimum distance between the two ends of the opening of the second upper rotating hole is larger than the width of the cross section of the mounting portion, so that the second upper rotating shaft can be separated from the opening, thereby realizing the installation and removal of the second upper rotating shaft and the second upper rotating hole.

[0097] Optionally, the length direction of the cross section of the mounting portion extends along the direction from the door body 60 to the box body 50 , and the width direction of the cross section of the mounting portion extends along the left-right direction.

[0098] In the disclosed embodiment, the length direction of the cross section of the mounting portion extends along the direction from the door body 60 to the box body 50, and the width direction extends along the left-right direction, that is, the cross section of the mounting portion is rectangular, so that the second upper rotation hole can move along the length direction of the cross section of the mounting portion, thereby realizing the installation and removal of the second upper rotation hole and the second upper rotation shaft. In this way, the second upper rotation shaft and the first upper hinge can be installed and removed along the direction of the door body 60 and the box body 50, further improving the installation convenience of the door body 60 and the box body 50.

[0099] Optionally, when the door body 60 is covered at the opening of the box body 50, the extension direction of the line connecting the two open ends of the second upper rotating hole is the same as the extension direction of the width of the cross section of the mounting portion or there is an angle between them.

[0100] In the disclosed embodiment, when the extension direction of the line connecting the two ends of the opening of the second upper rotating hole is the same as the extension direction of the width of the cross section of the mounting portion, the first upper hinge can be disassembled without rotating the first upper hinge when the door body 60 is closed. When the extension direction of the line connecting the two ends of the opening of the second upper rotating hole is at an angle to the extension direction of the width of the cross section of the mounting portion, when the first upper hinge needs to be disassembled, it is necessary to rotate a certain angle to make the extension direction of the line connecting the two ends of the opening the same as the extension direction of the width of the cross section of the mounting portion, and then disassemble the first upper hinge from the second upper rotating shaft, so as to prevent the door body 60 and the box body 50 from falling off when subjected to external force and being disassembled by mistake.

[0101] For example, the opening of the second upper rotating hole faces the left side, so when the first upper hinge needs to be removed, the door body 60 needs to be rotated 125° before it can be removed from the second upper rotating shaft.

[0102] Optionally, the second upper rotating shaft is arranged at the upper end of the box body 50 and extends upward, the first upper hinge is arranged at the upper end of the door body 60, the first upper hinge includes a first connecting part 401, a second connecting part 401 and a third connecting part 401, the first connecting part 401 is connected to the door body 60; one end of the second connecting part 401 is provided with a second upper rotating hole, the second upper rotating hole can be sleeved on the outside of the second upper rotating shaft, the second connecting part 401 is parallel to the first connecting part 401 and is staggered; the third connecting part 401 is connected between the first connecting part 401 and the other end of the second connecting part 401, and the third connecting part 401 extends in the direction from the box body 50 to the door body 60.

[0103] In the embodiment of the present disclosure, the first connection part 401 is used to realize the connection between the door body 60 and the first upper hinge. The second connection part 401 is used to set the second upper rotation hole, and the third connection part 401 extends in the direction from the box body 50 to the door body 60 so that there is a distance between the first connection part 401 and the second connection part 401, thereby being able to leave enough space for the door body 60 and the box body 50, so that the door body 60 can rotate relative to the box body 50.

[0104] Alternatively, if Figures 10 to 17 As shown, the door body 60 is constructed with a first lower rotating hole, the first lower rotating hole opens downward, the first lower rotating hole can be sleeved from top to bottom on the outside of the first lower rotating shaft, and the lower rotating shaft 73 includes the first lower rotating shaft, or, the lower hinge assembly 70 includes an upper hinge plate 71, the upper hinge plate 71 is connected to the door body 60, the upper hinge plate 71 is constructed with a second lower rotating hole 712, the second lower rotating hole 712 can be sleeved from top to bottom on the outside of the second lower rotating shaft 721, and the lower rotating shaft includes the second lower rotating shaft 721.

[0105] In the disclosed embodiment, the lower rotating shaft needs to be inserted into the rotating hole to realize the rotation of the rotating hole relative to the lower rotating shaft. Here, the door body 60 can be directly provided with a first lower rotating hole, and the first lower rotating shaft can be directly inserted into the first lower rotating hole. This structure is simple and easy to process. Similarly, the door body 60 can also be provided with a lower hinge plate 72, and the lower hinge plate 72 is provided with a second lower rotating hole 712, and the second lower rotating hole 712 can cooperate with the second lower rotating shaft 721.

[0106] Optionally, the lower hinge assembly 70 is installed on a refrigeration device, which includes a door body 60 and a box body 50. The lower hinge assembly 70 includes an upper hinge plate 71 and a lower hinge plate 72. The upper hinge plate 71 is connected to the lower end of the door body 60. The lower wall surface of the upper hinge plate 71 is provided with a rotating protrusion 711. The lower wall surface of the rotating protrusion 711 is constructed with a second lower rotating hole 712 and a stop portion, and the second lower rotating hole 712 extends along the height direction of the rotating protrusion 711; the upper wall surface of the lower hinge plate 72 is provided with a second lower rotating shaft 721, and the second lower rotating shaft 721 extends upward. The second lower rotating shaft 721 can be rotatably arranged in the second lower rotating hole 712, and the outer wall surface of the second lower rotating shaft 721 is constructed with a stop fitting portion adapted to the stop portion; wherein, when the stop portion cooperates with the stop fitting portion, the second lower rotating shaft 721 limits rotation relative to the second lower rotating hole 712.

[0107] In the embodiment of the present disclosure, when the second lower rotating shaft 721 rotates in the second lower rotating hole 712, the door body 60 and the box body 50 can be rotated. The stopper and the second lower rotating hole 712 are both provided on the lower wall surface of the rotating protrusion 711, and the stopper matching portion is provided on the outer wall surface of the second lower rotating shaft 721, so that when the door body 60 is opened to the second preset angle, the stopper and the stopper matching portion cooperate to limit the rotation of the second lower rotating shaft 721 and the second lower rotating hole 712, so that the movement of the door body 60 can be stopped to prevent the door body 60 from colliding with foreign objects due to excessive opening angle.

[0108] Optionally, the lower wall portion of the rotating protrusion 711 protrudes downward 722 to form a first stop protrusion 714, the outer wall surface of the second lower rotating shaft 721 is constructed with a protrusion 722 extending along its circumference, and the upper wall portion of the protrusion 722 protrudes upward 722 to form a second stop protrusion 724, and when the stop portion cooperates with the stop matching portion, the side surface of the first stop protrusion 714 abuts against the side surface of the second stop protrusion 724, wherein the stop portion includes the first stop protrusion 714, and the stop matching portion includes the second stop protrusion 724.

[0109] In the embodiment of the present disclosure, the lower wall surface portion of the rotating protrusion 711 protrudes downward 722 to form a first stop protrusion 714, and the upper wall surface portion of the protrusion 722 disposed around the outer wall of the second lower rotating shaft 721 protrudes upward 722 to form a second stop protrusion 724, so that during the rotation of the second lower rotating hole 712 around the second lower rotating shaft 721, the side elevation of the first stop protrusion 714 and the side elevation of the second stop protrusion 724 can abut against each other, thereby limiting the rotation of the second lower rotating hole 712 relative to the second lower rotating shaft 721. The first stop protrusion 714 and the second stop protrusion 724 are simple in structure, easy to implement, low in cost, and have good application prospects.

[0110] Optionally, the lower wall surface of the first stop protrusion 714 is configured with a first sliding surface 715, the upper wall surface of the protrusion 722 is configured with a second sliding surface 725 adapted to the first sliding surface 715, and the second stop protrusion 724 protrudes upward from the upper wall surface of the second sliding surface 725; the second sliding surface 725 includes a first lifting section 7251 and a horizontal section 7252 connected to each other, the first lifting section 7251 and the horizontal section 7252 are sequentially arranged along the rotation direction of the upper hinge plate 71 when the door body 60 is opened, the horizontal section 7252 extends in the horizontal direction, and the height of the first lifting section 7251 gradually increases along the rotation direction of the upper hinge plate 71 when the door body 60 is opened;

[0111] The first sliding surface 715 includes a second lifting section 7151 matched with the first lifting section 7251. When the door body 60 is closed, the first end of the second lifting section 7151 corresponds to and abuts against an end of the first lifting section 7251 away from the horizontal section 7252. When the door body 60 is opened to a first preset angle, the first end of the second lifting section 7151 abuts against the connection between the first lifting section 7251 and the horizontal section 7252. Here, the connection between the first lifting section 7251 and the horizontal section 7252 is not strictly the connection between the first lifting section 7251 and the horizontal section 7252, but may also be a position close to the connection.

[0112] In the embodiment of the present disclosure, when the second lower rotating hole 712 rotates around the second lower rotating shaft 721, the first sliding surface 715 and the second sliding surface 725 contact and cooperate with each other, wherein the first lifting section 7251 and the horizontal section 7252 of the second sliding surface 725 make the second sliding surface 725 spiral, and similarly, the first sliding surface 715 is provided with a second lifting section 7151 matching the first lifting section 7251, so that when the door body 60 is opened from a closed state, the first end of the second lifting section 7151 moves from the first end of the first lifting section 7251 (the end away from the horizontal section) along the first lifting section 7251 toward the second end of the first lifting section 7251 (the end connected to the horizontal section), and when the first end of the second lifting section 7151 moves to the connection between the first lifting section 7251 and the horizontal section 7252, the door body 60 can hover. When no force is applied to the door body 60 , under the guidance of the first lifting section 7251 , the first end of the second lifting section 7151 moves toward the first end of the first lifting section 7251 under its own gravity, thereby enabling automatic closing of the door body 60 .

[0113] In practical applications, the cooperation between the first sliding surface 715 and the second sliding surface 725 can realize the hovering of the door body 60, and can also realize the automatic closing of the door body 60 when the opening angle is relatively small.

[0114] Optionally, the first stop protrusion 714 includes a first side elevation 7141, which is located at the second end of the first sliding surface 715, and the second stop protrusion 724 includes a second side elevation 7241, which is located at the second end of the second sliding surface 725, wherein, when the door body 60 is closed, the first end of the first sliding surface 715 corresponds to the first end of the second sliding surface 725, and the first side elevation 7141 and the second side elevation 7241 are spaced apart; when the door body 60 is opened to a second preset angle, the second end of the first sliding surface 715 corresponds to the second end of the second sliding surface 725, and the first side elevation 7141 abuts against the second side elevation 7241 to limit the upper hinge plate 71 from rotating in the direction of opening the door body 60.

[0115] In the embodiment of the present disclosure, the lengths of the first sliding surface 715 and the second sliding surface 725 are different, so that enough space can be reserved to allow the second lower rotating hole 712 to rotate around the second lower rotating shaft 721. Therefore, when the door body 60 is closed, the first end of the first sliding surface 715 corresponds to the first end of the second sliding surface 725, and the first side elevation 7141 is spaced from the second side elevation 7241. When the door body 60 is opened to a preset angle, the first sliding surface 715 moves along the second sliding surface 725, and when the first side elevation 7141 and the second side elevation 7241 abut against each other, the door body 60 cannot continue to rotate, thereby achieving the stopping of the door body 60.

[0116] It should be noted that the first end of the first sliding surface 715 is the first end of the second lifting section 7151 , and the first end of the second sliding surface 725 is the first end of the first lifting section 7251 .

[0117] Optionally, the lower wall surface of the first stop protrusion 714 is also constructed with a third sliding surface 716, and the third sliding surface 716 is higher than the first sliding surface 715.

The first end of the fourth sliding surface 726 is connected to the first end of the second sliding surface 725, and the fourth sliding surface 726 is higher than the height of the first end of the second sliding surface 725. When the door body 60 is closed, the third sliding surface 716 abuts against the fourth sliding surface 726, and when the door body 60 is opened, the third sliding surface 716 and the fourth sliding surface 726 are separated.

[0118] In the disclosed embodiment, the third sliding surface 716 and the fourth sliding surface 726 increase the circumferential contact area between the rotating protrusion 711 and the second lower rotating shaft 721 when the door body 60 is closed, thereby improving the connection stability of the hinge assembly and the movement stability of the door body 60 when it is opened from a closed state.

[0119] Optionally, the first stop protrusion 714 also includes a third side facade 7142 arranged opposite to the first side facade 7141, the third sliding surface 716 is connected between the third side facade 7142 and the first end of the first sliding surface 715, and the connection between the third sliding surface 716 and the first sliding surface 715 forms a first stop surface 7161; the second stop protrusion 724 also includes a fourth side facade 7242 corresponding to the second side facade 7241, and the fourth side facade 7242 is connected to the first end of the second sliding surface 725; wherein, when the door body 60 is closed, the first stop surface 7161 and the fourth side facade 7242 abut against each other to limit the upper hinge plate 71 from rotating in the direction of closing the door body 60; when the door body 60 is opened, the first stop surface 7161 and the fourth side facade 7242 are separated.

[0120] In the disclosed embodiment, when the door body 60 is closed, the first stop surface 7161 and the fourth side elevation surface 7242 abut against each other, which can limit the door body 60 from rotating inward and play a certain stopping role in the closing direction of the door body 60.

[0121] Optionally, the lower wall surface of the rotating protrusion 711 is also constructed with a fifth sliding surface 717, and the fifth sliding surface 717 is connected between the two ends of the first stop protrusion 714; the second stop protrusion 724 is in an arc shape extending along the circumference of the second lower rotating shaft 721, and the upper wall surface of the second stop protrusion 724 is also constructed with a sixth sliding surface 727 adapted to the fifth sliding surface 717, and the sixth sliding surface 727 is higher than the fourth sliding surface 726; wherein, when the door body 60 is closed, the fifth sliding surface 717 abuts against the sixth sliding surface 727, and when the door body 60 is opened, the fifth sliding surface 717 and the sixth sliding surface 727 are separated.

[0122] In the disclosed embodiment, the fifth sliding surface 717 and the sixth sliding surface 727 further increase the contact area between the rotating protrusion 711 and the protrusion 722. In this way, when the door body 60 is closed, the setting stability of the lower hinge assembly 70 can be increased, and when the door body 60 is opened from the closed state, the rotation stability of the upper hinge plate 71 can be increased.

[0123] Optionally, a second stop surface 7271 is formed at the connection between the fourth sliding surface 726 and the sixth sliding surface 727. When the door body 60 is closed, the second stop surface 7271 abuts against the third side vertical surface 7142 to limit the upper hinge plate 71 from rotating in the direction of opening the door body 60; when the door body 60 is opened, the second stop surface 7271 is separated from the third side vertical surface 7142.

[0124] In the disclosed embodiment, when the door body 60 is closed, the second stop surface 7271 and the third side elevation surface 7142 abut against each other, which can limit the door body 60 from rotating inward and play a certain stopping role in the closing direction of the door body 60.

[0125] It can be understood that the first sliding surface 715, the third sliding surface 716 and the fifth sliding surface 717 are sequentially arranged on the lower wall surface of the rotating protrusion 711 along the circumference of the rotating protrusion 711, and the first sliding surface 715, the third sliding surface 716 and the fifth sliding surface 717 have different heights, thereby forming the first stop surface 7161, the first side vertical surface 7141 and the third side vertical surface 7142. In this way, the circumferential stability of the second lower rotating hole 712 when rotating around the second lower rotating shaft 721 can be improved, and the setting of multiple stop surfaces can improve the stopping effect on the door body 60.

[0126] Similarly, the second sliding surface 725, the fourth sliding surface 726 and the sixth sliding surface 727 are sequentially arranged on the upper wall surface of the protrusion 722 in the circumferential direction of the second lower rotating shaft 721, and the second sliding surface 725, the fourth sliding surface 726 and the sixth sliding surface 727 have different heights, thereby forming the second stop surface 7271, the second side vertical surface 7241 and the fourth side vertical surface 7242. In this way, the circumferential stability of the second lower rotating hole 712 when rotating around the second lower rotating shaft 721 can be improved, and the setting of multiple stop surfaces can improve the stopping effect on the door body 60.

[0127] Optionally, the protrusion 722 is in a ring shape extending circumferentially around the second lower rotating shaft 721 , and an outer side wall of the protrusion 722 extends upward to form an accommodating cavity 7221 , and a lower wall surface of the second lower rotating hole 712 is located in the accommodating cavity 7221 .

[0128] In the disclosed embodiment, the outer side surface of the protrusion 722 extends upward to form a receiving cavity 7221, so that the matching parts of the lower wall surface of the rotating protrusion 711 and the protrusion 722 of the second lower rotating shaft 721 are both located in the receiving cavity 7221, thereby hiding the matching structure and improving the appearance.

[0129] Optionally, when the refrigeration device includes a second upper hinge 40 and a lower hinge assembly, the second lower rotating shaft 721 corresponds to the first upper rotating shaft 10, that is, the distance between the center of the second lower rotating shaft 721 and the front wall of the box is the same as the distance between the first upper rotating shaft 10 and the front wall of the box. The distance between the center of the second lower rotating shaft 721 and the outer edge of the door body on the side close to the second lower rotating shaft 721 is the same as b. In this way, the thickness of the door body used can be reduced by the second upper hinge 40 and the lower hinge assembly 70, thereby reducing the overall size of the refrigeration device, achieving the door body rotation of 90 degrees to be flush with the box, and then the refrigeration device can be flatly embedded in the furniture to achieve home integration.
