[0050] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0051] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0052] like Figure 1-5 As shown, an embodiment of the present invention provides a refrigeration device 100, which can be a refrigerator, freezer, upright refrigerator, wine cabinet, etc.

[0053] The refrigeration equipment 100 includes a cabinet 10, a door 20, and a hinge 30. The cabinet 10 contains storage space 101 for storing food or other items. The door 20 is connected to the cabinet 10 via the hinge 30 and can rotate relative to the cabinet 10 to open or close the storage space 101. The cabinet 10 can contain multiple storage spaces 101, which can be categorized as refrigeration spaces, freezing spaces, and variable temperature spaces to meet the preservation needs of different items.

[0054] The door 20 has an open state and a closed state. When the door 20 is in the closed state, the storage space 101 is sealed by the door 20. When the door 20 is in the open state, one side of the storage space 101 is open, allowing the user to store or retrieve items from the storage space 101. When the door 20 switches from the closed state to the open state, the door 20 rotates relative to the cabinet 10 by a preset angle.

[0055] The hinge 30 includes a fixed seat 31 connected to the housing 10, a movable seat 32 connected to the door 20, and a linkage assembly 33 that movably connects the movable seat 32 and the fixed seat 31. The linkage assembly 33 has a folded state and an unfolded state, and the state of the linkage assembly 33 corresponds to the state of the door 20. When the door 20 is closed, the linkage assembly 33 is in the folded state (e.g., when the door 20 is closed). Figure 4 As shown), when the door 20 is in the open state, the linkage assembly 33 is in the unfolded state (as shown). Figure 5 As shown, when the door 20 rotates relative to the housing 10 to switch from the closed state to the open state, the linkage assembly 33 unfolds from the folded state to the unfolded state. Conversely, when the door 20 rotates relative to the housing 10 to switch from the open state to the closed state, the linkage assembly 33 folds from the unfolded state to the folded state.

[0056] The refrigeration equipment 100 also includes a drive assembly 40 that connects the housing 10 and the linkage assembly 33 for automatically opening and closing the door 20. The drive assembly 40 can drive the linkage assembly 33 to switch between a folded state and an unfolded state, thereby causing the door 20 to open and close automatically.

[0057] The drive assembly 40 is located outside the housing 10 and includes a telescopic drive member 41 and a connecting frame 42. The telescopic drive member 41 includes a drive part 411 fixedly connected to the housing 10 and a telescopic rod 412 driven by the drive part 411 to extend and retract along the axial direction of the drive part 411. One end of the connecting frame 42 is rotatably connected to the telescopic rod 412, and the other end is rotatably connected to the connecting rod assembly 33. The axial direction of the drive part 411 is parallel to the width direction of the housing 10. For ease of explanation, the end of the connecting frame 42 rotatably connected to the telescopic rod 412 is referred to as the first end, and the end rotatably connected to the connecting rod assembly 33 is referred to as the second end.

[0058] It should be noted that in this article, the up and down direction refers to the position of the refrigeration equipment 100. Figure 1 The vertical direction shown can be understood as the height direction of the housing 10; the front-back direction is the position of the refrigeration device 100. Figure 2 The left and right directions are shown in the diagram, where the left side is the front and the right side is the rear. The front and rear directions can be understood as the thickness direction of the housing 10; the width direction of the housing 10 refers to the position of the refrigeration device 100. Figure 1 The left and right directions in the state shown.

[0059] When the drive unit 411 drives the telescopic rod 412 to move along the width direction of the housing 10, the telescopic rod 412 will drive the first end of the connecting frame 42 to move along the width direction of the housing 10. In this way, the connecting frame 42 will drive the linkage assembly 33 to unfold or fold, thereby causing the door 20 to rotate. While driving the linkage assembly 33 to unfold or fold, the connecting frame 42 will also rotate itself. When the telescopic rod 412 extends relative to the drive unit 411, the door 20 opens; when the telescopic rod 412 retracts relative to the drive unit 411, the door 20 closes.

[0060] In this embodiment, the telescopic drive component 41 can be a drive element such as a cylinder, hydraulic cylinder, or electric push rod.

[0061] In other embodiments, the telescopic drive member 41 can also be an elastic damping member. That is, the drive part 411 includes a housing and an elastic member disposed between the housing and the telescopic rod 412. When the telescopic rod 412 extends relative to the drive part 411 under the action of an external force, the elastic member accumulates elastic potential energy. When the telescopic rod 412 is not subjected to an external force, the elastic potential energy of the elastic member is released, causing the telescopic rod 412 to automatically retract relative to the drive part 411. With the above configuration, when the user manually opens the door 20, it drives the telescopic rod 412 to extend out of the drive part 411 and causes the elastic member to accumulate elastic potential energy. Afterwards, when the user releases the door 20, the telescopic rod 412 can automatically retract under the action of the elastic member, so that the door 20 can automatically close. It can be seen that the drive assembly 40 can only drive the door 20 to close automatically.

[0062] like Figure 6-7As shown, in this embodiment, the refrigeration device 100 further includes a first decorative cover 50 connected to the connecting frame 42 to at least partially cover the connecting frame 42, and a second decorative cover 60 connected to the telescopic rod 412 to at least partially cover the telescopic rod 412. The connecting frame 42 and the telescopic rod 412 are components that move when the drive assembly 40 drives the door 20 to rotate. When the connecting frame 42 moves, the first decorative cover 50 moves with the connecting frame 42, and when the telescopic rod 412 moves, the second decorative cover 60 moves with the telescopic rod 412. The first decorative cover 50 and the second decorative cover 60 prevent the connecting frame 42 and the telescopic rod 412 from being directly exposed outside the cabinet 10, making the refrigeration device 100 more aesthetically pleasing and reducing the risk of accidentally pinching the user when the connecting frame 42 and the telescopic rod 412 move.

[0063] Furthermore, the refrigeration device 100 also includes a third cover 70 connected to the drive unit 411 to at least partially cover the drive unit 411, the third cover 70 covering the drive unit 411, further enhancing the aesthetics of the refrigeration device 100.

[0064] The drive unit 411 is fixedly connected to the housing 10. In other embodiments, the third decorative cover 70 may be connected to the housing 10 instead of the drive unit 411.

[0065] In this embodiment, the door 20 and the housing 10 are in a relative rotational relationship. It is conceivable that in other embodiments, the drive unit 411 may not be fixedly connected to the housing 10, but rather fixedly connected to the door 20.

[0066] like Figure 8-9 As shown, the first decorative cover 50 is generally U-shaped, covering the upper, lower, and front sides of the connecting frame 42. The rear side of the connecting frame 42 is the housing 10, which can be left uncovered. Specifically, the first decorative cover 50 is connected to the connecting frame 42 by a snap-fit ​​mechanism. It includes two first cover bodies 51 located on the upper and lower sides of the connecting frame 42, and a second cover body 52 located on the front side of the connecting frame 42. The second cover body 52 connects the two first cover bodies 51. The two first cover bodies 51 abut against the upper and lower sides of the connecting frame 42, respectively, and the second cover body 52 abuts against the front side of the connecting frame 42. The first cover body 51 also has a snap-fit ​​part 53 that abuts against the rear side of the connecting frame 42. Thus, the first decorative cover 50 cannot move relative to the connecting frame 42 in the vertical and horizontal directions or in the front and back directions.

[0067] When the first cover 50 and the connecting bracket 42 are snapped together, the connecting bracket 42 can be snapped into the first cover 50 from the "opening" formed between the two first cover bodies 51 away from the second cover body 52. ​​The snap-fit ​​part 53 may have a first guide surface 531 extending in an inclined or arc shape on the side opposite to the second cover body 52 to facilitate the snap-fit ​​of the connecting bracket 42 into the cover. The two first cover bodies 51 are specifically provided with a plurality of snap-fit ​​parts 53.

[0068] Furthermore, the connecting frame 42 is provided with a positioning hole 421, the axis of which extends in the front-rear direction. The first cover 50 also includes a positioning post 54 extending from the second cover 52 into the positioning hole 421. Thus, the first cover 50 cannot move along the length of the connecting frame 42 on the connecting frame 42.

[0069] It is conceivable that, in addition to being connected to the connecting frame 42 by the aforementioned snap-fit ​​method, in other embodiments, the first decorative cover 50 can also be connected to the connecting frame 42 by other means, such as by fasteners such as screws.

[0070] like Figure 10-11 As shown, in this embodiment, when the telescopic rod 412 extends or retracts relative to the drive unit 411 along the width direction of the housing 10, the second decorative cover 60 moves along the telescopic rod 412. The second decorative cover 60 is also slidably connected to the drive unit 411 along the width direction of the housing 10, that is, the second decorative cover 60 can only move along the width direction of the housing 10, and its movement trajectory is consistent with the movement trajectory of the telescopic rod 412. The third decorative cover 70 is located outside the second decorative cover 60. When the second decorative cover 60 moves along the width direction of the housing 10, it enters and extends into the third decorative cover 70.

[0071] The second cover 60 is generally U-shaped, covering the upper, lower, and front sides of the telescopic rod 412. The rear side of the telescopic rod 412 is the housing 10 and does not need to be covered. Specifically, the second cover 60 includes two third covers 61 located on the upper and lower sides of the telescopic rod 412, and a fourth cover 62 located on the front side of the telescopic rod 412. The fourth cover 62 connects the two third covers 61. Each of the two third covers 61 has a first abutment 611 abutting against the outer periphery of the driving part 411, and the fourth cover 62 has a second abutment 621 abutting against the outer periphery of the driving part 411. The angle between the second abutment 621 and any one of the first abutment 611 in the circumferential direction of the driving part 411 is greater than 90°. Thus, the second cover 60 cannot move relative to the driving part 411 in the vertical and horizontal directions or the front and back directions, but can only slide on the driving part 411 in the width direction of the housing 10.

[0072] In a preferred embodiment, the second abutment 621 and two first abutment parts 611 are evenly distributed around the drive part 411, that is, the angle between the second abutment part 621 and any one of the first abutment parts 611 in the circumferential direction of the drive part 411 is equal to 120°. Multiple first abutment parts 611 are provided on the third cover 61, and multiple second abutment parts 621 are also provided on the fourth cover 62.

[0073] The second decorative cover 60 is connected to the telescopic rod 412 by a snap-fit ​​mechanism. Specifically, a retaining ring 412a is connected to the outer periphery of the telescopic rod 412, and a retaining groove 63 matching the retaining ring 412a is formed on the second decorative cover 60. When the retaining ring 412a is engaged in the retaining groove 63, the second decorative cover 60 can move along the width direction of the box body 10 together with the telescopic rod 412.

[0074] It is conceivable that, in addition to being connected to the telescopic rod 412 by the aforementioned snap-fit ​​method, in other embodiments, the second decorative cover 60 can also be connected to the telescopic rod 412 by other means, such as by fasteners such as screws.

[0075] In other embodiments, the second cover 60 may also be slidably connected to the third cover 70 along the width direction of the housing 10.

[0076] like Figure 12-14 As shown, the third cover 70 is generally U-shaped, covering the upper, lower, and front sides of the drive unit 411. The rear side of the drive unit 411 is the housing 10, which does not need to be covered. Specifically, the third cover 70 is connected to the drive unit 411 by a snap-fit ​​mechanism. It includes two fifth cover bodies 71 located on the upper and lower sides of the drive unit 411, and a sixth cover body 72 located on the front side of the drive unit 411. The sixth cover body 72 connects the two fifth cover bodies 71. A first abutment block 711 and a second abutment block 712 are formed on the two fifth cover bodies 71, respectively. The first abutment blocks 711 and the second abutment blocks 712 abut against the rear side of the drive unit 411, and the first abutment blocks 711 and the second abutment blocks 712 also abut against the upper and lower sides of the drive unit 411, respectively. The two fifth cover bodies 71 also abut against the housing 10 in the front-back direction.

[0077] The third cover 70 may also include a seventh cover 73 connecting the two fifth covers 71 and the sixth cover 72, the seventh cover 73 being located on the side of the telescopic drive 41 away from the hinge 30 in the width direction of the housing 10.

[0078] The drive unit 411 is fixedly connected to the housing 10. In this case, the two fifth covers 71 abut against the housing 10 in the front-rear direction, and the first abutment block 711 and the second abutment block 712 abut against the rear side of the drive unit 411, so that the third cover 70 cannot move relative to the drive unit 411 in the front-rear direction. The first abutment block 711 and the second abutment block 712 abut against the upper and lower sides of the drive unit 411 respectively, so that the third cover 70 cannot move relative to the drive unit 411 in the vertical direction.

[0079] The drive unit 411 is provided with a limiting groove 411a, a first limiting surface 411b and a second limiting surface 411c located on both sides of the limiting groove 411a in the width direction of the housing 10, and at least one first abutting block 711 or a second abutting block 712 located in the limiting groove 411a, between the first limiting surface 411b and the second limiting surface 411c, so that the third decorative cover 70 cannot move relative to the drive unit 411 in the width direction of the housing 10.

[0080] In this embodiment, the drive unit 411 is provided with a first slide groove 411d-1 that cooperates with the first abutment block 711 and a second slide groove 411d-2 that cooperates with the second abutment block 712. The first slide groove 411d-1 and the second slide groove 411d-2 both extend along the width direction of the housing 10. The first abutment block 711 can enter the first slide groove 411d-1 along the width direction of the housing 10, and the second abutment block 712 can enter the second slide groove 411d-2 along the width direction of the housing 10.

[0081] As a preferred embodiment, multiple first abutment blocks 711 and multiple second abutment blocks 712 are provided, and the multiple first abutment blocks 711 and multiple second abutment blocks 712 are arranged one-to-one in the vertical direction. Two limiting grooves 411a are provided, namely a first limiting groove and a second limiting groove. The first limiting groove and the second limiting groove are symmetrically arranged on the upper and lower sides of the driving part 411 so that a first abutment block 711 and a second abutment block 712 can enter therein respectively.

[0082] When the third cover 70 needs to be engaged with the drive unit 411, first align the first abutment block 711 with the first slide groove 411d-1 and the second abutment block 712 with the second slide groove 411d-2. Then, drive the third cover 70 to move along the width direction of the housing 10 until one of the first abutment blocks 711 enters the first limiting groove and one of the second abutment blocks 712 enters the second limiting groove.

[0083] In order to enable a first abutment block 711 and a second abutment block 712 to enter the two limiting grooves 411a, the drive unit 411 is also provided with two second guide surfaces 411e-1 and third guide surfaces 411e-2 that extend in an inclined or arc shape. In the width direction of the housing 10, the second guide surface 411e-1 is located on one side of the first limiting groove, and the third guide surface 411e-2 is located on one side of the second limiting groove.

[0084] It is conceivable that, in addition to being connected to the drive unit 411 by the aforementioned snap-fit ​​method, in other embodiments, the third decorative cover 70 may also be connected to the drive unit 411 by other means, such as by fasteners such as screws.

[0085] like Figure 13 , 15 As shown in -19, the drive unit 411 includes a housing 411f, a hook portion 411g and a connecting portion 411h formed on both sides of the housing 411f in the axial direction, and a telescopic rod 412 connected to the housing 411f.

[0086] The hook portion 411g includes a first extension portion 411g-1 extending rearward from the housing 411f and a second extension portion 411g-2 extending from the first extension portion 411g-1 in a direction away from the connecting portion 411h. The housing 411f, the first extension portion 411g-1, and the second extension portion 411g-2 surround and form a snap-fit ​​groove 411m. The housing 10 is provided with an insertion port 102 for inserting the hook portion 411g to allow part of the housing 10 to be located in the snap-fit ​​groove 411m. The connecting portion 411h is connected to the housing 10 by fasteners. When fixing the drive unit 411 to the housing 10, the hook portion 411g can be inserted into the insertion port 102 on the housing 10 first, so that part of the housing 10 enters the snap-fit ​​groove 63, and then the connection can be fixed to the housing 10 by fasteners. In this way, it is convenient to connect the telescopic drive member 41 to the housing 10.

[0087] To facilitate the insertion of the hook portion 411g into the socket 102, the second extension portion 411g-2 is divided into two parts: a first part 411g-21 extending from the first extension portion 411g-1 in a direction away from the connecting portion 411h, and a second part 411g-22 extending from the first part 411g-21 in a direction away from the connecting portion 411h. The second part 411g-22 extends backward relative to the first part 411g-21, and its size in the front-rear direction gradually decreases in the direction away from the connecting portion 411h.

[0088] Furthermore, a positioning opening 103 is provided on the side of the housing 10 facing the shell 411f, and a positioning part 411n is formed on the shell 411f that is inserted into the positioning opening 103. The positioning part 411n is inserted into the positioning opening 103, which defines the position of the shell 411f relative to the housing 10 in the width direction and the vertical direction.

[0089] In this embodiment, the length of the first decorative cover 50 is greater than the length of the connecting frame 42, and both ends of the first decorative cover 50 extend beyond both ends of the connecting frame 42 in the length direction. The second decorative cover 60 extends beyond the end of the telescopic rod 412 near the hinge 30 in the width direction of the housing 10, and both ends of the cover extend beyond both ends of the drive unit 411 in the width direction of the housing 10. With the above arrangement, the first decorative cover 50, the second decorative cover 60, and the third decorative cover 70 can completely cover the connecting frame 42, the telescopic rod 412, and the drive unit 411 from the top, bottom, and front sides, respectively, with the first decorative cover 50 partially covering the second decorative cover 60.

[0090] like Figure 4-5 As shown in Figures 18-19, in this embodiment, the linkage assembly 33 includes multiple linkages. Specifically, the linkage assembly 33 includes a first linkage 331, a second linkage 332, a third linkage 333, and a fourth linkage 334. One end of the first linkage 331 is rotatably connected to the fixed base 31. One end of the second linkage 332 is rotatably connected to the first linkage 331, and the other end is rotatably connected to the movable base 32. One end of the third linkage 333 is rotatably connected to the first linkage 331, and the other end is rotatably connected to the movable base 32. One end of the fourth linkage 334 is rotatably connected to the fixed base 31, and the other end is rotatably connected to the third linkage 333. The rotational connection position between the second link 332 and the first link 331 is closer to the telescopic drive member 41 than the rotational connection position between the third link 333 and the first link 331. The rotational connection position between the second link 332 and the movable seat 32 is closer to the telescopic drive member 41 than the rotational connection position between the third link 333 and the movable seat 32. The second end of the connecting frame 42 is rotatably connected to the first link 331.

[0091] When the telescopic rod 412 of the telescopic drive member 41 extends relative to the drive part 411 along the width direction of the housing 10, that is, when the telescopic rod 412 moves toward the hinge 30, it will drive the first end of the connecting frame 42 to move along the width direction of the housing 10, and cause the rotational connection position of the first link 331 and the connecting frame 42 to move away from the fixed seat 31. The first link 331 will also rotate relative to the fixed seat 31. Since the first link 331, the second link 332, the third link 333, and the fourth link 334 are linked, the second link 332, the third link 333, and the first link 331 will also rotate relative to the fixed seat 31 accordingly, so that the entire linkage assembly 33 can be unfolded and the door 20 will open accordingly. When the connecting frame 42 drives the linkage assembly 33 to unfold, the connecting frame 42 itself also rotates relative to the telescopic rod 412 and the first link 331. Conversely, when the telescopic rod 412 of the telescopic drive member 41 retracts relative to the drive part 411 along the width direction of the housing 10, the linkage assembly 33 will fold from the unfolded state, and the door 20 will close accordingly.

[0092] In a preferred embodiment, the rotational connection position between the second end of the first link 331 and the connecting frame 42 is closer to the telescopic drive member 41 than the rotational connection position between the second link 332 and the first link 331. As described above, the rotational connection position between the second link 332 and the first link 331 is closer to the telescopic drive member 41 than the rotational connection position between the third link 333 and the first link 331. Therefore, comparatively, the rotational connection position between the first link 331 and the second end of the connecting frame 42 is closest to the telescopic drive member 41. This reduces the required length of the connecting frame 42 and eliminates the need to consider interference issues between the connecting frame 42 and the second link 332 and the third link 333 during the folding and unfolding of the link assembly 33.

[0093] Specifically, the first connecting rod 331 includes a rod body 331a and a reinforcing iron 331b fixedly connected to the side of the rod body 331a near the telescopic drive member 41. The reinforcing iron 331b has a reinforcing portion 331b-1 that abuts against the rod body 331a along the length direction of the first connecting rod 331. The reinforcing iron 331b can be fixed to the side of the rod body 331a facing the housing 10 by means of screws or welding. The reinforcing portion 331b-1 abuts against the rod body 331a along the length direction of the first connecting rod 331, which can prevent the reinforcing iron 331b from breaking during rotation. The aforementioned fixed base 31 is rotatably connected to one end of the rod body 331a, and the connecting frame 42 is rotatably connected to the reinforcing iron 331b. The rotatable connection position of the connecting frame 42 and the reinforcing iron 331b is set closer to the housing 10 than the rotatable connection positions of the first connecting rod 331 and the second connecting rod 332.

[0094] The reinforcing iron 331b is made of metal to provide structural strength. The other components of the hinge 30 assembly, namely the fixed seat 31, the movable seat 32, the first link 331, the second link 332, the third link 333, and the fourth link 334, are also made of metal. In this way, the hinge 30 can bear the weight of the door 20 and reliably allow the door 20 to rotate relative to the housing 10.

[0095] In other embodiments, it is conceivable that the second end of the connecting frame 42 may also be rotatably connected to one of the second link 332, the third link 333, and the fourth link 334.

[0096] In summary, the refrigeration device 100 provided in this embodiment includes the following steps during assembly:

[0097] The telescopic drive component 41 is installed on the housing 10. Specifically, the hook portion 411g on the drive component 411 is first inserted into the insertion port 102 of the housing 10, and then the connecting portion 411h and the housing 10 are connected by fasteners such as screws. During this process, the positioning portion 411n is inserted into the positioning port 103.

[0098] The reinforcing iron 331b is pre-connected to the rod 331a with fasteners such as screws to form the first connecting rod 331. Then, the fixing seat 31 of the hinge 30 is connected to the housing 10.

[0099] Install the connecting bracket 42, and rotatably connect one end of the connecting bracket 42 to the telescopic rod 412 and the other end to the first connecting rod 331 via a pin;

[0100] The first decorative cover 50 is snapped onto the connecting bracket 42;

[0101] The second cover 60 is snapped onto the telescopic rod 412 and the second cover 60 is slidably connected to the drive unit 411;

[0102] The third decorative cover 70 is snapped onto the drive unit 411. Specifically, the first abutment block 711 is aligned with the first slide groove 411d-1 and the second abutment block 712 is aligned with the second slide groove 411d-2. Then, the third decorative cover 70 is driven to move along the width direction of the housing 10 until one of the first abutment blocks 711 enters the first limiting groove 411a and one of the second abutment blocks 712 enters the second limiting groove 411a.
