[0042] The application will be described in detail below with reference to the embodiments shown in the drawings. However, the embodiments do not limit the application, and the changes in structure, method, or function made by those skilled in the art based on the embodiments are included in the protection scope of the application.

[0043] The terms for indicating spatial relative positions such as "upper", "lower", "left", "right", "front", "back", and the like used herein are for the purpose of facilitating the description to describe the relationship of one feature relative to another feature as shown in the drawings. It can be understood that the terms for indicating spatial relative positions can be intended to include different orientations other than those shown in the drawings, and should not be construed as limiting the claims. In addition, the descriptive word "horizontal" used herein is not completely equivalent to along the direction perpendicular to the direction of gravity, and a certain angle of inclination is allowed.

[0044] As shown in FIGS. 1-7, an embodiment of the application provides a refrigeration device 100, which can be a refrigerator, a freezer, a vertical refrigerator, a wine cabinet, or the like.

[0045] The refrigeration device 100 includes a cabinet 10, a door body 20, and a hinge 30. The cabinet 10 is internally formed with a storage space 11 for storing food or other articles. The door body 20 is connected to the cabinet 10 by the hinge 30 and can rotate relative to the cabinet 10 to open or close the storage space 11. The cabinet 10 can be internally formed with multiple storage spaces 11, which can be divided into a refrigeration space, a freezing space, and a variable-temperature space to meet the storage requirements of different articles.

[0046] The door body 20 has an open state and a closed state. When the door body 20 is in the closed state (as shown in FIGS. 1-2 and 4), the storage space 11 is closed by the door body 20. When the door body 20 is in the open state (as shown in FIG. 6), one side of the storage space 11 is open, and at this time, the user can store articles in the storage space 11 or take articles out of the storage space 11. When the door body 20 switches from the closed state to the open state, the door body 20 rotates relative to the cabinet 10 by a predetermined angle.

[0047] The hinge 30 comprises a fixed seat 1 connected to the cabinet 10, a movable seat 2 connected to the door body 20, and a linkage assembly 3 movably connecting the movable seat 2 and the fixed seat 1. The linkage assembly 3 has a folded state and an unfolded state, and the state of the linkage assembly 3 and the state of the door body 20 are in a corresponding relationship. When the door body 20 is in the closed state, the linkage assembly 3 is in the folded state (as shown in FIG. 4). When the door body 20 is in the open state, the linkage assembly 3 is in the unfolded state (as shown in FIG. 7). When the door body 20 rotates relative to the cabinet 10 to switch from the closed state to the open state, the linkage assembly 3 unfolds from the folded state to the unfolded state; conversely, when the door body 20 rotates relative to the cabinet 10 to switch from the open state to the closed state, the linkage assembly 3 folds from the unfolded state to the folded state.

[0048] The refrigeration device 100 further comprises an electric drive assembly 4 connected to the door body 20 and the linkage assembly 3. The electric drive assembly 4, when powered, can drive the linkage assembly 3 to switch between the folded state and the unfolded state. In this way, by electrically controlling the electric linkage assembly 3, the door body 20 can be driven to switch between the closed state and the open state, so as to realize the automatic opening and closing of the door body 20. The electric drive assembly 4 is connected to the door body 20 and does not occupy the space inside the cabinet 10 to affect the capacity of the storage space 11.

[0049] In this embodiment, the linkage assembly 3 comprises a plurality of linkages 31. The electric drive assembly 4 comprises an electric drive 41 and a connecting frame 42. The electric drive 41 comprises a fixed portion 411 fixed to the door body 20 and an output portion 412 movable relative to the fixed portion 411. When the electric drive 41 is powered, the output portion 412 moves relative to the fixed portion 411 along the width direction of the door body 20. The connecting frame 42 comprises a first end and a second end, the first end is rotatably connected to the output portion 412, and the second end is rotatably connected to one of the plurality of linkages 31. The second end is arranged closer to the cabinet 10 than the first end. When the electric drive 41 is powered, the output portion 412 moves relative to the fixed portion 411 along the width direction of the door body 20, and the first end of the connecting frame 42 will move along the width direction of the door body 20 accordingly. In this way, the connecting frame 42 will drive the linkage 31 connected thereto to rotate, so as to unfold or fold the entire linkage assembly 3, and correspondingly, the door body 20 will also rotate relative to the cabinet 10, thereby opening or closing the storage space 11.

[0050] In this embodiment, the width direction of the door body 20 is the left-right direction when the door body 20 is in the state shown in FIG. 1, the up-down direction can be understood as the height direction of the door body 20, i.e., the up-down direction is perpendicular to the width direction of the door body 20, and the thickness direction of the door body 20 is the left-right direction when the door body 20 is in the state shown in FIG. 2.

[0051] In one embodiment, the linkage assembly 3 comprises a first linkage 311, a second linkage 312, a third linkage 313, and a fourth linkage 314. One end of the first linkage 311 is rotatably connected to the fixed seat 1. One end of the second linkage 312 is rotatably connected to the first linkage 311, and the other end is rotatably connected to the movable seat 2. One end of the third linkage 313 is rotatably connected to the first linkage 311, and the other end is rotatably connected to the movable seat 2. One end of the fourth linkage 314 is rotatably connected to the fixed seat 1, and the other end is rotatably connected to the third linkage 313.

[0052] The rotatable connection position of the second linkage 312 and the first linkage 311 is closer to the electric drive 41 than the rotatable connection position of the third linkage 313 and the first linkage 311. The rotatable connection position of the second linkage 312 and the movable seat 2 is closer to the electric drive 41 than the rotatable connection position of the third linkage 313 and the movable seat 2. The second end of the connecting frame 42 is rotatably connected to the first linkage 311.

[0053] When the electric drive 41 is energized, the first end of the connecting frame 42 moves along the width direction of the door body 20, which causes the rotatable connection position of the first linkage 311 and the second end to move away from the movable seat 2, and the first linkage 311 rotates relative to the fixed seat 1. Since the first linkage 311 is linked with the second linkage 312, the third linkage 313, and the fourth linkage 314, the second linkage 312, the third linkage 313, and the first linkage 311 also rotate relative to the fixed seat 1 accordingly, so that the entire linkage assembly 3 can be unfolded or folded. When the connecting frame 42 drives the linkage assembly 3 to unfold or fold, the connecting frame 42 itself also rotates relative to the output portion 412 and the first linkage 311.

[0054] In one embodiment, when the electric drive 41 drives the first end of the connecting frame 42 to move along the width direction of the door body 20 towards the hinge 30, the linkage assembly 3 unfolds from the folded state, and the door body 20 opens accordingly. Conversely, when the electric drive 41 drives the first end of the connecting frame 42 to move along the width direction of the door body 20 and away from the hinge 30, the linkage assembly 3 folds from the unfolded state, and the door body 20 closes accordingly.

[0055] In one embodiment, the rotation connecting position of the first link 311 and the second end is closer to the electric drive 41 than the rotation connecting position of the second link 312 and the first link 311. As mentioned above, the rotation connecting position of the second link 312 and the first link 311 is closer to the electric drive 41 than the rotation connecting position of the third link 313 and the first link 311. Therefore, the rotation connecting position of the first link 311 and the second end is the closest to the electric drive 41. In this way, the required length of the connecting frame 42 can be reduced, and the interference problem between the connecting frame 42 and the second link 312 and the third link 313 during the folding and unfolding of the link assembly 3 can be avoided.

[0056] In one embodiment, the first link 311 comprises a link body 3111 and a reinforcing member 3112 fixed to the link body 3111 near the side of the electric drive 41. In some embodiments, the reinforcing member 3112 is made of reinforcing iron. The reinforcing member 3112 has an abutting portion 3113 abutting with the link body 3111 along the length direction of the first link 311. In embodiments, the reinforcing member 3112 can be fixed to the side of the link body 3111 towards the box 10 by welding or screwing, etc. The abutting portion 3113 abutting with the link body 3111 along the length direction of the first link 311 can prevent the reinforcing member 3112 from breaking during rotation. One end of the link body 3111 is rotationally connected to the fixed seat 1, and the second end of the reinforcing member 3112 is rotationally connected to the second end. The rotation connecting position of the second end and the reinforcing member 3112 is closer to the box 10 than the rotation connecting position of the first link 311 and the second link 312.

[0057] The reinforcing member 3112 is made of metal material to have a certain structural strength. The rest of the components of the hinge 30 assembly, including the fixed seat 1, the movable seat 2, the first link 311, the second link 312, the third link 313, and the fourth link 314, are also made of metal material. In this way, the hinge 30 can bear the weight of the door body 20 and reliably rotate the door body 20 relative to the box 10.

[0058] In other embodiments, the second end of the connecting frame 42 can also be rotationally connected to one of the second link 312, the third link 313, and the fourth link 314.

[0059] In combination with Figs. 8-15, in the present embodiment, the door body 20 comprises a door body 21 and a decorative box 22 connected to the door body 21. The decorative box 22 can be made of plastic material and has a receiving cavity 23. The electric drive member 41 is hidden in the receiving cavity 23. The decorative box 22 covers the electric drive member 41, so that the user is difficult to touch the electric drive member 41 when using the refrigeration equipment 100. The arrangement of the decorative box 22 ensures the safety of the user and also beautifies the appearance of the refrigeration equipment 100.

[0060] The receiving cavity 23 has a clearance opening 24 matched with the connecting frame 42. The connecting frame 42 extends from the receiving cavity 23 to the outside of the decorative box 22 through the clearance opening 24. The arrangement of the clearance opening 24 provides space for the movement of the connecting frame 42, so that the connecting frame 42 and the decorative box 22 do not interfere with each other when the door body 20 switches between the closed state and the open state.

[0061] The connecting frame 42 is at least partially located in the receiving cavity 23. In an embodiment, the connecting frame 42 is arc-shaped and protrudes relative to the cabinet 10 when the door body 20 is in the closed state. The arc-shaped connecting frame 42 can match the rotation track of the door body 20, so as to reduce the size of the clearance opening 24 in the width direction of the door body 20 and the size of the connecting frame 42 exposed outside the receiving cavity 23 during the rotation of the door body 20. As shown in Fig. 4, the arc-shaped connecting frame 42 can be roughly divided into a first frame body 424 close to the output portion 412 and a second frame body 425 close to the first connecting rod 311. The extension direction of the second frame body 425 is shown by the dashed line E in Fig. 5. Compared with the case where the connecting frame 42 extends linearly, the extension direction of the second frame body 425 of the arc-shaped connecting frame 42 is smaller in the angle with the first connecting rod 311, so that the driving force required by the electric drive member 41 to drive the rotation of the door body 20 is reduced.

[0062] In an embodiment, the connecting frame 42 has a substantially U-shaped cross section, including a first plate body 421 and a second plate body 422 arranged in a vertical direction, and a connecting plate 423 connecting the first plate body 421 and the second plate body 422. The clearance 24 includes a first clearance 241 and a second clearance 242. The first clearance 241 is formed on the side of the decorative box 22 close to the hinge 30 when the door body 20 is in a closed state. Two second clearances 242 are formed on the side of the decorative box 22 close to the cabinet 10 when the door body 20 is in a closed state. The two second clearances 242 are respectively matched with the first plate body 421 and the second plate body 422. Since the first plate body 421 and the second plate body 422 are relatively thin, the two second clearances 242 can have a strip shape, and only need to allow the first plate body 421 and the second plate body 422 to pass through. In this way, the second clearance 242 occupies a smaller area, and accordingly, the decorative cover 222 can cover the electric drive member 41 as much as possible, and the electric drive member 41 can be better hidden in the receiving cavity 23.

[0063] In the embodiment, the electric drive member 41 is an electric support rod 43, which is a standard part available on the market. The electric support rod 43 includes a housing 431 and a telescopic rod 432 telescopically arranged relative to the housing 431. The housing 431 is fixed to the door body 21. After the electric support rod 43 is powered, the telescopic rod 432 can move relative to the housing 431 in the width direction of the door body 20. The first end of the connecting frame 42 is rotationally connected to the telescopic rod 432. After the electric support rod 43 is powered, the telescopic rod 432 drives the first end of the connecting frame 42 to move in the width direction of the door body 20, thereby automatically opening and closing the door body 20. It can be seen that the fixed part 411 is the housing 431, and the output part 412 is the telescopic rod 432.

[0064] The door body 20 further includes a mounting seat 25 fixed to the door body 21. The mounting seat 25 has at least two connecting heads 251 in a spherical shape. The housing 431 is formed with at least two grooves 4311 matched with the at least two connecting heads 251. The at least two connecting heads 251 are respectively clamped in the at least two grooves 4311, so that the housing 431 is fixedly connected to the mounting seat 25. In the embodiment, the connecting head 251 and the groove 4311 are both provided with two, and the mounting seat 25 is specifically connected to the door body 20 by fasteners such as screws.

[0065] In some embodiments, the mounting seat 25 is formed with a positioning groove 252, and the door body 21 is formed with a positioning protrusion 212 matched with the positioning groove 252. When the mounting seat 25 is fixed to the door body 21, the positioning protrusion 212 can be first fitted into the positioning groove 252, so that the mounting seat 25 can be fixed to a predetermined position of the door body 21. The number of the positioning groove 252 and the positioning protrusion 212 is equal, and both can be provided with two or more.

[0066] In some other embodiments, the door body 21 is provided with a positioning slot 252, and the mounting seat 25 is provided with a positioning protrusion 212 matched with the positioning slot 252.

[0067] In some other embodiments, the electric drive 41 can also be a linear motor or other element capable of outputting linear displacement after being powered.

[0068] In the present embodiment, the decorative box 22 comprises a box body 221 having an opening 2211 on one side, and a cover 222 connected with the box body 221 to close the opening 2211. The box body 221 and the cover 222 form a receiving cavity 23, and the box body 221 is connected with the door body 20. When connecting the decorative box 22 with the door body 21, the box body 221 is first connected with the door body 20, and the electric drive 41 is arranged in the receiving cavity 23 through the opening 2211, and then the cover 222 is connected with the box body 221 to close the opening 2211. In one embodiment, the opening 2211 is located on the side of the box body 221 facing the cabinet 10 when the door body 20 is in the closed state.

[0069] In the present embodiment, the door body 21 has a first end face 211 at the upper end or the lower end. The electric drive 41 is arranged in one and fixedly connected with the first end face 211. The door body 20 further comprises a connecting portion 26 protruding from the first end face 211, which comprises a connecting plate 261 and a connecting portion 262, wherein the connecting plate 261 is arranged spaced apart from the first end face 211, and the connecting portion 262 connects the first end face 211 and the connecting plate 261. In the width direction of the door body 20, the size of the connecting plate 261 is greater than that of the connecting portion 262. The box body 221 is located on one side of the first end face 211 in the up-down direction and has a first side wall 2212 close to the first end face 211, and the first side wall 2212 is provided with a connecting hole 2213. In the width direction of the door body 20, the size of the connecting hole 2213 is greater than that of the connecting portion 262, but less than that of the connecting plate 261. In the up-down direction, the distance between the connecting plate 261 and the first end face 211 is not less than the size of the first side wall 2212.

[0070] After the above arrangement, moving the box body 221 in the thickness direction of the door body 20 can make the connecting portion 26 enter the connecting hole 2213 (as shown in FIG. 14), the first side wall 2212 of the box body 221 is located between the connecting plate 261 and the first end face 211, and the first side wall 2212 and the connecting plate 261 at least partially overlap in the up-down direction, so that the box body 221 cannot be separated from the door body 21 in the up-down direction.

[0071] The door body 21 comprises a first buckle groove 213 formed by being recessed from the first end face 211, and the first side wall 2212 is provided with a first buckle 2214 matched with the first buckle groove 213, and after the first buckle 2214 is buckled into the first buckle groove 213, the box body 221 cannot move relative to the door body 21 along the width direction and the thickness direction of the door body 20.

[0072] Through the cooperation of the clamping part 26 and the clamping surface 2213 and the cooperation of the first buckle groove 213 and the first buckle 2214, the box body 221 can be reliably clamped and connected to the door body 21.

[0073] The decorative cover 222 comprises a decorative cover body 2221 and a side strip 2222 extending from the decorative cover body 2221 towards the box body 221.
