Detailed implementation method

[0045] The present utility model will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present utility model, and any changes in structure, method, or function made by those of ordinary skill in the art based on these embodiments are included within the protection scope of the present utility model.

[0046] Spatial relative position terms used herein, such as "upper", "lower", "left", "right", "front", "rear", etc., are for the purpose of facilitating description of the relationship of one feature relative to another as shown in the accompanying drawings. It can be understood that depending on the placement position of the product, the spatial relative position terms may be intended to include different orientations other than those shown in the figures, and should not be construed as a limitation on the claims. Additionally, the descriptive term "horizontal" used herein is not exactly equivalent to being perpendicular to the direction of gravity, and a certain degree of inclination is allowed.

[0047] As Figure 1 -7 shows, a refrigeration device 100 provided by an embodiment of the present utility model may be a refrigerator, a freezer, a vertical refrigerator, a wine cabinet, etc.

[0048] The refrigeration device 100 includes a box body 10, a door body 20, and a hinge 30. A storage space 11 for storing food or other items is formed inside the box body 10. The door body 20 is connected to the box body 10 through the hinge 30 and can rotate relative to the box body 10 to open or close the storage space 11. Multiple storage spaces 11 may be formed inside the box body 10, and the multiple storage spaces 11 can be divided into a refrigerating space, a freezing space, and a variable temperature space to meet the preservation requirements of different items.

[0049] The door body 20 has an open state and a closed state. When the door body 20 is in the closed state (as Figure 1 -2, 4 show), the storage space 11 is closed by the door body 20. When the door body 20 is in the open state (as Figure 6 shown), one side of the storage space 11 is open. At this time, the user can store items in the storage space 11 or take items 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 a preset angle relative to the box body 10.

[0050] The hinge 30 includes a fixed seat 1 connected to the box body 10, a movable seat 2 connected to the door body 20, and a connecting rod assembly 3 that movably connects the movable seat 2 and the fixed seat 1. The connecting rod assembly 3 has a folded state and an unfolded state, and the state of the connecting rod assembly 3 corresponds to the state of the door body 20. When the door body 20 is in the closed state, the connecting rod assembly 3 is in the folded state (as Figure 4 shown), and when the door body 20 is in the open state, the connecting rod assembly 3 is in the unfolded state (as Figure 7As shown. When the door body 20 rotates relative to the box body 10 to switch from the closed state to the open state, the link assembly 3 unfolds from the folded state to the unfolded state; conversely, when the door body 20 rotates relative to the box body 10 to switch from the open state to the closed state, the link assembly 3 folds from the unfolded state to the folded state.

[0051] The refrigeration device 100 further includes an electric drive assembly 4 connecting the door body 20 and the link assembly 3. When the electric drive assembly 4 is powered on, it can drive the link assembly 3 to switch between the folded state and the unfolded state. Thus, by electrically controlling the electric link assembly 3, the door body 20 can be driven to switch between the closed state and the open state to achieve 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 box body 10 to affect the capacity of the storage space 11.

[0052] In this embodiment, the link assembly 3 includes a plurality of links 31, and the electric drive assembly 4 includes an electric drive member 41 and a connecting frame 42. The electric drive member 41 includes a fixing portion 411 fixed to the door body 20 and an output portion 412 that moves relative to the fixing portion 411 in the width direction of the door body 20 when the electric drive member 41 is powered on. The connecting frame 42 includes 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 links 31. The second end is disposed closer to the box body 10 than the first end. When the electric drive member 41 is powered on, the output portion 412 moves relative to the fixing portion 411 in the width direction of the door body 20, and the first end of the connecting frame 42 will correspondingly move in the width direction of the door body 20. Thus, the connecting frame 42 will drive the link 31 connected thereto to rotate, causing the entire link assembly 3 to unfold or fold. Correspondingly, the door body 20 will also rotate relative to the box body 10 to open or close the storage space 11.

[0053] It should be noted that herein, the width direction of the door body 20 is the left - right direction when the door body 20 is in the Figure 1 state shown. The up - down direction can be understood as the height direction of the door body 20, that is, the up - down direction is perpendicular to the width direction of the door body 20. The thickness direction of the door body 20 is the left - right direction when the door body 20 is in the Figure 2 state shown.

[0054] Specifically, the link assembly 3 includes a first link 311, a second link 312, a third link 313, and a fourth link 314. One end of the first link 311 is rotatably connected to the fixed seat 1, one end of the second link 312 is rotatably connected to the first link 311, and the other end is rotatably connected to the movable seat 2. One end of the third link 313 is rotatably connected to the first link 311, and the other end is rotatably connected to the movable seat 2. One end of the fourth link 314 is rotatably connected to the fixed seat 1, and the other end is rotatably connected to the third link 313. Among them, the rotational connection position of the second link 312 and the first link 311 is closer to the electric drive member 41 than the rotational connection position of the third link 313 and the first link 311. The rotational connection position of the second link 312 and the movable seat 2 is closer to the electric drive member 41 than the rotational connection position of the third link 313 and the movable seat 2. The second end of the connecting frame 42 is rotatably connected to the first link 311.

[0055] When the electric drive member 41 is energized, the first end of the connecting frame 42 moves along the width direction of the door body 20, which will cause the rotational connection position of the first link 311 and the second end to move away from the movable seat 2. The first link 311 will also rotate relative to the fixed seat 1. And because the first link 311 is linked with the second link 312, the third link 313, and the fourth link 314, the second link 312, the third link 313, and the first link 311 will also rotate relative to the fixed seat 1 accordingly, so that the entire link assembly 3 can be unfolded or folded. When the connecting frame 42 drives the link assembly 3 to unfold or fold, the connecting frame 42 itself is also rotating relative to the output portion 412 and the first link 311. Specifically, when the electric drive member 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 link assembly 3 will unfold from the folded state, and the door body 20 will open accordingly. On the contrary, when the electric drive member 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 link assembly 3 will fold from the unfolded state, and the door body 20 will close accordingly.

[0056] As a preferred solution of this embodiment, the rotational connection position of the first link 311 and the second end is closer to the electric drive member 41 than the rotational connection position of the second link 312 and the first link 311. As described above, the rotational connection position of the second link 312 and the first link 311 is closer to the electric drive member 41 than the rotational connection position of the third link 313 and the first link 311. Therefore, comparatively speaking, the rotational connection position of the first link 311 and the second end is the closest to the electric drive member 41. In this way, the required length of the connecting frame 42 can be reduced, and there is no need to consider the interference problem between the connecting frame 42, the second link 312, and the third link 313 during the folding and unfolding process of the link assembly 3.

[0057] Specifically, the first link 311 includes a link body 3111 and a reinforcing iron 3112 fixedly connected to the side of the link body 3111 close to the electric drive member 41. The reinforcing iron 3112 has an abutting portion 3113 that abuts against the link body 3111 along the length direction of the first link 311. The reinforcing iron 3112 can be specifically fixed to the side of the link body 3111 facing the box body 10 by means such as welding or screw connection. The abutting portion 3113 abuts against the link body 3111 along the length direction of the first link 311, which can prevent the reinforcing iron 3112 from breaking when rotating. One end of the above-mentioned fixed seat 1 is rotatably connected to the link body 3111, and the second end is rotatably connected to the reinforcing iron 3112. The rotation connection position of the second end and the reinforcing iron 3112 is closer to the box body 10 than the rotation connection position of the first link 311 and the second link 312.

[0058] The reinforcing iron 3112 is made of a metal material to have a certain structural strength. The remaining components of the hinge 30 assembly, namely 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 materials. In this way, the hinge 30 can bear the weight of the door body 20 and can reliably rotate the door body 20 relative to the box body 10.

[0059] It can be imagined that in other embodiments, the second end of the connecting frame 42 can also be rotatably connected to one of the second link 312, the third link 313, and the fourth link 314.

[0060] Continue to cooperate Figure 8 As shown in FIGS. 11-15, in this embodiment, the door body 20 includes a door body 21 and a decorative box 22 connected to the door body 21. The decorative box 22 can be specifically made of a 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. When the user uses the refrigeration device 100, it is difficult to touch the electric drive member 41. The setting of the decorative box 22 ensures the safety of the user and also plays a role in beautifying the appearance of the refrigeration device 100.

[0061] The receiving cavity 23 has an avoidance opening 24 that matches the connecting frame 42. The connecting frame 42 extends from the receiving cavity 23 to the outside of the decorative box 22 through the avoidance opening 24. The setting of the avoidance opening 24 can prevent the connecting frame 42 and the decorative box 22 from interfering when the door body 20 switches between the closed state and the open state.

[0062] The connecting frame 42 is at least partially located within the receiving cavity 23. As a preferred solution of this 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 connecting frame 42 is arranged in an arc shape. On the one hand, it can match the rotation trajectory of the door body 20 to reduce the size occupied by the avoidance 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. On the other hand, as Figure 4 shown, the arc-shaped connecting frame 42 can be generally divided into a first frame body 424 close to the output part 412 and a second frame body 425 close to the first connecting rod 311. The extending direction of the second frame body 425 is as shown by the dotted line E in Figure 5 . It can be imagined that, compared with the case where the connecting frame 42 extends linearly, when the connecting frame 42 is arranged in an arc shape, the included angle between the extending direction of its second frame body 425 and the first connecting rod 311 is smaller. Thus, the driving force required for the electric driving part 41 to drive the door body 20 to rotate can be reduced.

[0063] Specifically, the cross-section of the connecting frame 42 is generally U-shaped, including a first plate body 421 and a second plate body 422 arranged at intervals in the up-down direction, and a connecting plate 423 connecting the first plate body 421 and the second plate body 422. The avoidance opening 24 includes a first avoidance opening 241 opened on one side of the decorative box 22 close to the hinge 30 when the door body 20 is in the closed state, and two second avoidance openings 242 opened on one side of the decorative box 22 close to the cabinet 10 when the door body 20 is in the closed state. The two second avoidance openings 242 respectively match the first plate body 421 and the second plate body 421. Since the first plate body 421 and the second plate body 422 are relatively thin, the two second avoidance openings 242 can be strip-shaped, and only need to allow the first plate body 421 and the second plate body 422 to pass through. Thus, the area occupied by the second avoidance openings 242 is relatively small. Correspondingly, the decorative cover 222 can cover the electric driving part 41 as much as possible, and the electric driving part 41 can be better hidden in the receiving cavity 23.

[0064] In this embodiment, the electric driving part 41 is an electric strut 43. The electric strut 43 is a standard part that can be purchased on the market. It includes a housing 431 and a telescopic rod 432 that can be telescopically arranged relative to the housing 431. The housing 431 is fixed to the door body 21. After the electric strut 43 is powered on, 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 rotatably connected to the telescopic rod 432. After the electric strut 4 is powered on, the telescopic rod 432 drives the first end of the connecting frame 42 to move in the width direction of the door body 20, and the door body 20 can be automatically opened and closed. It can be seen that the above-mentioned fixing part 411 is the housing 431, and the above-mentioned output part 412 is the telescopic rod 432.

[0065] The door body 20 further includes a mounting base 25 fixed to the door main body 21. The mounting base 25 has at least two spherical connectors 251. At least two grooves 4311 are formed on the housing 431 and are matched with the at least two connectors 251. The at least two connectors 251 are respectively clamped in the at least two grooves 4311. In this way, the housing 431 is fixedly connected to the mounting base 25. In this embodiment, both the connector 251 and the groove 4311 are provided with two. The mounting base 25 is specifically connected to the door body 20 through fasteners such as screws.

[0066] A positioning groove 252 is formed on the mounting base 25, and a positioning protrusion 212 matched with the positioning groove 252 is formed on the door main body 21. When fixing the mounting base 25 to the door main body 21, the positioning protrusion 212 can be first inserted into the positioning groove 252 so that the mounting base 25 can be fixed to a predetermined position on the door main 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.

[0067] It can be conceived that a positioning groove 252 can also be formed on the door main body 21, and a positioning protrusion 212 matched with the positioning groove 252 is formed on the mounting base 25.

[0068] In other embodiments, the electric driving member 41 can also be other elements such as a linear motor that can output a linear displacement after being energized.

[0069] In this embodiment, the decorative box 22 includes a box body 221 with an opening 2211 on one side, and a decorative cover 222 that is snap-connected to the box body 221 to close the opening 2211. The box body 221 and the decorative cover 222 enclose a receiving cavity 23. The box body 221 is snap-connected to the door body 20. When connecting the decorative box 22 to the door main body 21, first snap-connect the box body 221 to the door body 20, and make the electric driving member 41 enter the receiving cavity 23 through the opening 2211. Then snap-connect the decorative cover 222 to the box body 221 to close the opening 2211. In this embodiment, the opening 2211 is specifically located on the side of the box body 221 facing the box body 10 when the door body 20 is in the closed state.

[0070] In this embodiment, the door body 21 has a first end face 211 located at its upper or lower end. There is one electric driving member 41, which is fixedly connected to the first end face 211. The door body 20 further includes a clamping portion 26 protruding from the first end face 211. The clamping portion 26 includes a clamping plate 261 spaced from the first end face 211 and a connecting portion 262 connecting the first end face 211 and the clamping plate 261. In the width direction of the door body 20, the size occupied by the clamping plate 261 is larger than that occupied by the connecting portion 262. The box body 221 is located on one side of the first end face 211 in the up and down direction and has a first side wall 2212 close to the first end face 211. A clamping opening 2213 is formed on the first side wall 2212. In the width direction of the door body 20, the size occupied by the clamping opening 2213 is larger than that occupied by the connecting portion 262 but smaller than that occupied by the clamping plate 261. In the up and down direction, the distance between the clamping plate 261 and the first end face 211 is not less than the size occupied by the first side wall 2212.

[0071] After the above settings are adopted, by moving the box body 221 along the thickness direction of the door body 20, the clamping portion 26 can be made to enter the clamping opening 2213 (as Figure 14 shown). The first side wall 2212 of the box body 221 is located between the clamping plate 261 and the first end face 211, and the first side wall 2212 and the clamping plate 261 at least partially overlap in the up and down direction, so that the box body 221 cannot be separated from the door body 21 in the up and down direction.

[0072] The door body 21 includes a first snap groove 213 recessed from the first end face 211. A first snap 2214 is formed on the first side wall 2212 and is matched with the first snap groove 213. After the first snap 2214 is snapped into the first snap groove 213, the box body 221 cannot move relative to the door body 21 in the width direction and the thickness direction of the door body 20.

[0073] It can be seen that the cooperation between the clamping portion 26 and the clamping opening 2213 and the cooperation between the first snap groove 213 and the first snap 2214 can make the box body 221 be reliably clamped and connected to the door body 21.

[0074] The decorative cover 222 includes a decorative cover body 2221, a side strip 2222 extending from the decorative cover body 2221 towards the box body 221. The shape of the side strip 2222 is matched with the shape of the opening 2211. In this way, the side strip 2222 can be snapped into the opening 2211, so that the decorative cover 222 cannot move relative to the box body 221 in the width direction and the up and down direction of the door body 20. The decorative cover 222 further includes a second buckle 2223 extending from the side strip 2222 towards the inside of the receiving cavity 23 in the thickness direction of the door body 20. A second buckle groove 2215 matching the second buckle 2223 is recessed on the side wall of the box body 221. The second buckle 2223 and the second buckle groove 2215 cooperate with each other, and the decorative cover 222 cannot be separated from the box body 221 in the thickness direction of the door body 20.

[0075] It can be seen that the cooperation between the side strip 2222 and the opening 2211, and the cooperation between the second buckle 2223 and the second buckle groove 2215 can enable the decorative cover 222 to be reliably snap-connected to the box body 221.

[0076] In this embodiment, the first end face 211 is located at the lower end of the door body 21, and the electric drive assembly 4 is located below the door body 21, with a relatively low position, so that it is not easily touched by the user when using the refrigeration device 100.

[0077] It can be conceived that in other embodiments, the first end face 211 can also be located at the upper end of the door body 20. At this time, the electric drive assembly 4 is located above the door body 21, with a certain height, and it is also not easily touched by the user when using the refrigeration device 100.

[0078] Generally, the door body 20 is connected to the box body 10 through two hinges 30, and the two hinges 30 are respectively connected to the upper side and the lower side of the door body 20. It can be conceived that if the opening force required to open the door body 20 is relatively large, two electric drive assemblies 4 can be equipped on one door body 20. The two electric drive assemblies 4 respectively drive the link assemblies 3 of the two hinges 30 to switch between the folded state and the unfolded state. Using two electric drive parts, the driving force is relatively large, which can ensure that the door body 20 is opened.

[0079] In summary, the refrigeration device 100 provided by the present utility model has the following advantages:

[0080] An electric drive assembly 4 is provided between the door body 20 and the link assembly 3 of the hinge 30. When the electric drive assembly 4 is powered on, it can drive the link assembly 3 of the hinge 30 to switch between the folded state and the unfolded state, thereby realizing the automatic opening and closing of the door body 20. Moreover, the electric drive assembly 4 is connected to the door body 20 and does not occupy the internal space of the box body 10 to affect the capacity of the storage space 11.

[0081] The electric drive member 41 is hidden in the receiving cavity 23 of the decorative box 22. During the process of the electric drive member 41 driving the door body 20 to rotate, the structure of the electric drive member 41 is not exposed, making the appearance of the refrigeration device 100 more beautiful and the user safer when using the refrigeration device 100.
