The details are set forth below.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a refrigeration apparatus according to the prior art.

In the related art, a hinge structure of a refrigeration apparatus such as a refrigerator applied to opening and closing of a door body generally adopts a single hinge shaft design. For example, the case 11 of the refrigerator 10 is provided with a hinge fixing plate 12, the hinge fixing plate 12 is provided with a hinge shaft 13, the door 14 of the refrigerator 10 is provided with a shaft hole (not shown), the hinge shaft 13 is inserted into the shaft hole, and the hinge shaft 13 can rotate in the shaft hole, so that the door 14 can rotate relative to the case 11, thereby realizing opening and closing of the door 14.

As home style gradually progresses toward unity, concealment, and simplicity, the built-in installation of the refrigerator 10 has also occurred, such as by embedding the refrigerator 10 in a cabinet 15. However, the existing hinge structure is limited by adopting a design of a single hinge shaft, and the door 14 is beyond the outer side wall 111 of the box 11 in the process of rotating relative to the box 11, so that the door 14 has hidden dangers of interference and collision with external structures (such as a cabinet 15 and the like) in the rotating process.

In view of this, embodiments of the present invention provide a box apparatus capable of reducing the extent to which the door body extends beyond the outer sidewall of the box during rotation, as will be described in detail below.

Referring to fig. 2, fig. 2 is a schematic top view of an embodiment of a case device according to the present invention.

In one embodiment, the cabinet apparatus may be a refrigeration device such as a refrigerator, freezer, or the like. Of course, the case device may be another device having the case 20 and the door 30, and requiring the door 30 to be rotatable with respect to the case 20. The following description is given by taking the case device as an example of the refrigerator, and is only for discussion, and not limiting the specific form of the case device.

The housing means comprises a housing 20. The case 20 is a storage medium of the case device, and a user stores articles to be refrigerated or frozen in the case 20. Specifically, the inside of the case 20 is provided with a receiving space 21, the receiving space 21 has an opening 22, and articles to be refrigerated or frozen are stored in the receiving space 21 through the opening 22.

The case device further comprises a door 30, the door 30 being used for blocking the opening 22 of the accommodating space 21. When the door 30 is closed to the opening 22, i.e. the door 30 is in a closed state, a relatively closed space is formed inside the case 20 for storing articles. The door 30 is rotatably connected to the pivoting side 23 of the housing 20, i.e. the door 30 can rotate relative to the housing 20. The housing 20 also has a target side 24, with the pivot side 23 and the target side 24 being disposed opposite each other on either side of the opening 22. The pivoting side 23 and the target side 24 are oppositely disposed in a second direction (as indicated by arrow X in fig. 2, the same applies hereinafter) which is parallel to the plane in which the opening 22 lies (as indicated by plane a in fig. 2, the same applies hereinafter).

In one embodiment, the case apparatus further includes a hinge assembly 40. The hinge assembly 40 is disposed on the pivoting side 23 of the case 20, and the hinge assembly 40 pivotally connects the case 20 and the door 30, i.e., realizes a rotational connection between the case 20 and the door 30. Specifically, the hinge assembly 40 includes a first carrier 41 and a second carrier 42, the first carrier 41 is disposed on the case 20, and the second carrier 42 is disposed on the door 30.

It should be noted that the first carrier 41 may be integrally formed with the case 20, that is, the first carrier 41 may be a part of the case 20. Of course, the first carrier 41 may also be independent of the case 20. Similarly, the second carrier 42 may be integrally formed with the door 30, i.e., the second carrier 42 may be a part of the door 30. Of course, the second carrier 42 may also be independent of the door 30.

Referring to fig. 3 and 4 together, the hinge assembly 40 has a first side Y disposed opposite in a first direction (as indicated by arrow Y in fig. 3, the same applies hereinafter) ₁ And a second side Y ₂ And a third side X oppositely arranged along the second direction ₁ And a fourth side X ₂ Wherein the first direction is perpendicular to the second direction.

The hinge assembly 40 further includes a first swing link 43. The first swing link 43 has a first pivot portion 431 and a second pivot portion 432, the first swing link 43 is rotatably connected to the first carrier 41 through the first pivot portion 431, and the first swing link 43 is also rotatably connected to the second carrier 42 through the second pivot portion 432. The hinge assembly 40 also includes a second swing link 44. The second swing link 44 has a third pivot portion 441 and a fourth pivot portion 442, the second swing link 44 is rotatably connected to the first carrier 41 through the third pivot portion 441, and the second swing link 44 is also rotatably connected to the second carrier 42 through the fourth pivot portion 442.

When the hinge assembly 40 is in the initial state, the first pivot portion 431 and the third pivot portion 441 are close to the first side Y with respect to the second pivot portion 432 and the fourth pivot portion 442 in the first direction ₁ And the opposite directions of the first pivot portion 431 and the second pivot portion 432 are disposed obliquely with respect to the opposite directions of the third pivot portion 441 and the fourth pivot portion 442 for guiding the second carrier 42 to rotate with respect to the first carrier 41 and the second carrier 42 toward the fourth side X in the second direction ₂ And (5) moving.

For the hinge assembly 40 of the present embodiment applied to the above-mentioned case device, the hinge assembly 40 is in the initial state, which means that the door 30 is sealed to the opening 22. When the door 30 is blocked in the opening 22, the first pivot portion 431 and the third pivot portion 441 are away from the case 20 with respect to the second pivot portion 432 and the fourth pivot portion 442. In other words, the first pivot portion 431 is away from the case 20 with respect to the second pivot portion 432 and the fourth pivot portion 442, and the third pivot portion 441 is away from the case 20 with respect to the second pivot portion 432 and the fourth pivot portion 442. The opposite directions of the first pivot portion 431 and the second pivot portion 432 are inclined with respect to the opposite directions of the third pivot portion 441 and the fourth pivot portion 442, so that the door 30 is guided to rotate with respect to the case 20 during the opening of the door 30 with respect to the case 20 from the state of blocking the opening 22.

The first swing link 43 and the second swing link 44 swing to guide the door 30 to move toward the target side 24. In this way, in the process that the door 30 is opened relative to the case 20 from the state of closing the opening 22 under the guidance of the hinge assembly 40, the door 30 moves toward the target side 24 of the case 20, so that the extent to which the door 30 protrudes beyond the outer side wall of the case 20 is reduced, and the risk that the door 30 interferes with and collides with the external structure during the rotation process can be reduced. In other words, the present embodiment allows the gap between the case device and the external structure located beside the case device to be reduced, so that micro-gaps, or even seamless, can be achieved, which is advantageous for the case device to adopt an embedded installation mode. Fig. 5 shows the door 30 being opened relative to the case 20 from a state of closing the opening 22 under the guide of the hinge assembly 40.

Compared with the traditional hinge adopting the six-link design, the first swing rod 43 and the second swing rod 44 of the embodiment form a four-link mechanism, which means that the hinge assembly 40 of the embodiment has simple structure and lower cost, and meanwhile, the hinge assembly 40 acts smoothly and stably, which is beneficial to stably guiding the door body 30 to open and close. Compared with the conventional hinge adopting the track design, the hinge action is affected by the easy deposition of the residues in the track, but the swing of the swing rod is not easily affected by the residues deposited at the position of the hinge assembly 40 in this embodiment, that is, the influence of the residues deposited at the position of the hinge assembly 40 on the hinge assembly 40 is small.

It should be noted that the rotational connection between the pivot portion (i.e. the first to fourth pivot portions) and the carrier (i.e. the first to second carriers) may take the form of a lever and hole fit. For example, the pivoting portion is a lever structure, the carrier is provided with a pivoting hole 48, and the pivoting portion is rotatably embedded in the pivoting hole 48 on the carrier, so that the pivoting portion and the carrier can rotate relatively, as shown in the figure. Of course, in other embodiments of the present invention, the pivot portion may be a hole structure, and the carrier is provided with a corresponding pivot rod to achieve a rotational connection between the pivot portion and the carrier.

And the pivoting part can be integrated with the swing rod or be independent of the swing rod. For example, the first to fourth pivoting portions are each a lever structure, and the first pivoting portion 431 is a separate structure independent of the first swing link 43, the second pivoting portion 432 is a unitary structure with the first swing link 43, and the third pivoting portion 441 and the fourth pivoting portion 442 are each a separate structure independent of the second swing link 44. The first pivot portion 431, the third pivot portion 441, and the fourth pivot portion 442 may have a rivet structure, and a spacer may be further added between the first pivot portion 431, the third pivot portion 441, and the fourth pivot portion 442 and the corresponding swing rod.

In an embodiment, a distance a between the first pivot portion 431 and the third pivot portion 441 is smaller than a distance C between the second pivot portion 432 and the fourth pivot portion 442, as shown in fig. 3. In this way, in the process that the door 30 rotates relative to the case 20 from the state of blocking the opening 22, the first swing link 43 and the second swing link 44 swing, so that the door 30 can be guided to rotate away from the case 20, so that the door 30 does not block the opening 22, and a user is allowed to access the article in the accommodating space 21 of the case 20.

It should be noted that the distance between the different pivot portions should be understood as the minimum distance between the central axes of the different pivot portions. The pivot part and the bearing piece rotate relatively around the central axis of the pivot part.

In one embodiment, the housing assembly also typically includes a dock seal (not shown) disposed on the door 30. The door body 30 seals the opening 22 of the accommodating space 21 by the door seal, so that the accommodating space 21 can have a good sealing effect when the door body 30 is sealed in the opening 22.

When the door body 30 is blocked in the opening 22, the first swing link 43 is close to the target side 24 relative to the second swing link 44. In the process that the door body 30 rotates relative to the box body 20 from the state of blocking the opening 22, the distance that the fourth pivot portion 442 moves towards the box body 20 is smaller than the distance that the second pivot portion 432 moves away from the box body 20, so that the door body 30 integrally moves away from the box body 20, the structural stability of the door seal can be prevented from being influenced due to excessive extrusion of the door seal, and meanwhile interference and collision between the door body 30 and the box body 20 can be avoided as much as possible.

Further, when the door body 30 is blocked in the opening 22, the second pivot portion 432 is disposed close to the target side 24 with respect to the first pivot portion 431, i.e., the first swing link 43 is disposed obliquely toward the target side 24, as shown in fig. 2 and 3. In this way, in the process of rotating the door 30 relative to the case 20 in a state of closing the opening 22, the distance that the second pivot portion 432 moves away from the case 20 is greater than the distance that the fourth pivot portion 442 moves toward the case 20, so as to ensure that the door 30 moves away from the case 20 as a whole.

Further, a distance B between the first pivot portion 431 and the second pivot portion 432 is greater than a distance D between the third pivot portion 441 and the fourth pivot portion 442, as shown in fig. 3. In this way, in the process of rotating the door 30 relative to the case 20 in a state of closing the opening 22, the distance that the second pivot portion 432 moves away from the case 20 is greater than the distance that the fourth pivot portion 442 moves toward the case 20, so as to ensure that the door 30 moves away from the case 20 as a whole.

In one embodiment, the hinge assembly 40 further includes a stop 45. The stopper 45 is provided on the first carrier 41 and/or the second carrier 42. In other words, the stopper 45 is disposed on the first carrier 41, or the stopper 45 is disposed on the second carrier 42, or the stopper 45 is connected to the first carrier 41 and the second carrier 42, respectively. Fig. 4 shows an exemplary case in which the stopper 45 is provided to the first carrier 41. The stopper 45 of the present embodiment is used to limit the maximum door opening angle of the door body 30.

Specifically, when the door 30 is blocked in the opening 22, the first swing link 43 is close to the target side 24 with respect to the second swing link 44. During the rotation of the door 30 relative to the case 20 from the state of blocking the opening 22, the stopper 45 is abutted against the second swing link 44 to limit the maximum door opening angle of the door 30, as shown in fig. 6. In other words, when the second swing link 44 swings to abut the stopper 45, the door body 30 reaches the maximum door opening angle.

Further, when the door 30 is blocked in the opening 22, the fourth pivot portion 442 of the second swing link 44 is far from the target side 24 relative to the third pivot portion 441. In this way, the swing stroke of the second swing link 44 can be increased, and thus the maximum door opening angle of the door body 30 can be increased. For example, the maximum door opening angle of the door 30 of the present embodiment may reach 90 ° or more, for example, 120 °, 150 °. And, the risk of the second swing link 44 interfering with the first pivot portion 431 of the first swing link 43 and colliding can be reduced.

It should be noted that, in this embodiment, by adjusting the posture of the second swing link 44 when the door body 30 is plugged in the opening 22, the maximum swing stroke of the second swing link 44 may be adjusted, and thus the maximum door opening angle of the door body 30 may be adjusted. Specifically, the maximum door opening angle of the door body 30 is adjusted by adjusting the included angle between the second swing rod 44 and the first direction when the door body 30 is blocked in the opening 22, and the first direction is perpendicular to the plane where the opening 22 is located.

In an embodiment, when the thickness of the door body 30 is 50mm, the distance a between the first pivot portion 431 and the third pivot portion 441 is 20±1mm, the distance B between the first pivot portion 431 and the second pivot portion 432 is 27.2±1mm, the distance C between the second pivot portion 432 and the fourth pivot portion 442 is 40±2mm, and the distance D between the third pivot portion 441 and the fourth pivot portion 442 is 20.4±1mm.

In an alternative embodiment, when the thickness of the door body 30 is 60mm, the distance a between the first pivot portion 431 and the third pivot portion 441 is 24.5±1mm, the distance B between the first pivot portion 431 and the second pivot portion 432 is 36.4±1mm, the distance C between the second pivot portion 432 and the fourth pivot portion 442 is 50±2mm, and the distance D between the third pivot portion 441 and the fourth pivot portion 442 is 29.7±1mm.

In another alternative embodiment, when the thickness of the door body 30 is 77mm, the distance a between the first pivot portion 431 and the third pivot portion 441 is 28±1mm, the distance B between the first pivot portion 431 and the second pivot portion 432 is 41.2±1mm, the distance C between the second pivot portion 432 and the fourth pivot portion 442 is 59±2mm, and the distance D between the third pivot portion 441 and the fourth pivot portion 442 is 36.9±1mm.

When the door body 30 of the embodiment of the present invention has different thicknesses, the distance a between the first pivot portion 431 and the third pivot portion 441, the distance B between the first pivot portion 431 and the second pivot portion 432, the distance C between the second pivot portion 432 and the fourth pivot portion 442, and the distance D between the third pivot portion 441 and the fourth pivot portion 442 are reasonably set in the above manner, so that the degree of the door body 30 protruding beyond the outer side wall of the case 20 is reduced, the degree of the door body 30 extruding the door seal is reduced, and the risk of interference and collision of the door body 30 in the rotation process is reduced. In other words, the hinge assembly 40 disclosed in the embodiments of the present invention can be applied to door bodies 30 having different thicknesses.

It should be noted that the thickness of the door 30 should be understood as the length of the door 30 in the first direction when the door 30 is plugged into the opening 22.

Referring to fig. 7 and 8, fig. 7 is a schematic perspective view of a box device according to the present invention, and fig. 8 is a schematic view of a box device M shown in fig. 7.

In an embodiment, the first bearing member 41 and the case 20 may be assembled by a fastener such as a screw. If the second carrier 42 is also assembled with the door 30 by using fasteners such as screws, the assembly tolerance requirement between the second carrier 42 and the door 30 in the third direction (as shown by arrow Z in fig. 8, the same applies below) tends to be increased, and the assembly difficulty also increases.

The third direction is perpendicular to the plane defined by the first direction and the second direction. In other words, the third direction is the height direction of the door 30. The assembly of the fasteners such as screws requires high assembly tolerances in the height direction between the second carrier 42 and the door body 30.

In view of this, the second bearing member 42 of this embodiment is assembled with the door body 30 by shaft hole matching. Specifically, one of the second carrier 42 and the door body 30 is provided with a connection shaft 46, and the other is provided with a connection hole 47, and the connection shaft 46 is embedded in the connection hole 47 to fix the second carrier 42 to the door body 30.

The second bearing piece 42 and the door body 30 adopt a shaft hole matching mode, the hinge assembly 40 can be guaranteed to normally guide the door opening and closing action of the door body 30 only by embedding the connecting shaft 46 into the connecting hole 47, and the depth requirement for embedding the connecting shaft 46 into the connecting hole 47 is low, so that the assembly tolerance requirement of the second bearing piece 42 and the door body 30 in the third direction can be reduced, and the assembly difficulty can be reduced.

Fig. 8 exemplarily shows a case where the second carrier 42 is provided with the coupling shaft 46 and the door body 30 is provided with the coupling hole 47.

Referring to fig. 9 to 11, fig. 9 is a schematic structural view of another state of the case device shown in fig. 7, fig. 10 is a schematic structural view of an N region of the case device shown in fig. 9, and fig. 11 is a schematic structural view of an embodiment of the hinge assembly and the driving mechanism of the present invention.

In one embodiment, the housing apparatus further includes a drive mechanism 50. The driving mechanism 50 is in transmission connection with at least one swing link (including the first swing link 43, the second swing link 44, etc.) of the hinge assembly 40, and the driving mechanism 50 is used for driving the swing link to swing so as to drive the second carrier 42 to rotate relative to the first carrier 41. For the hinge assembly 40 of the present embodiment applied to the above-mentioned case device, the door 30 is driven to rotate relative to the case 20. In other words, the case device of the present embodiment realizes automatic opening and closing of the door 30 by the driving mechanism 50.

It should be noted that, the hinge assembly 40 of the present embodiment may be the hinge assembly 40 described in the foregoing embodiment, that is, the hinge assembly 40 includes a first swing link 43 and a second swing link 44, and the driving mechanism 50 is in driving connection with at least one of the first swing link 43 and the second swing link 44. Of course, the hinge assembly 40 of the present embodiment may also include a greater number of swing rods, for example, the hinge assembly 40 of the present embodiment adopts a six-bar mechanism, etc., which is not limited herein. The following description is given by taking the example that the hinge assembly 40 includes the first swing link 43 and the second swing link 44 as a discussion, and is not limiting.

In one embodiment, the drive mechanism 50 includes a drive member 51. The driving member 51 is used as a power element of the driving mechanism 50 and is used for driving the swing rod of the hinge assembly 40 to swing, so as to drive the hinge assembly 40 to drive the door body 30 to automatically open and close.

Alternatively, the driving member 51 may be a motor or the like, which is not limited herein.

The first swing link 43 has a first pivot portion 431 and a second pivot portion 432, and the second swing link 44 has a third pivot portion 441 and a fourth pivot portion 442, each of which adopts a lever structure. Considering that the pivoting portion rotates relative to the bearing member during the rotation of the door body 30, the present embodiment allows the driving member 51, such as a motor, to drive the pivoting portion to rotate, so that the swing rod to which the pivoting portion belongs swings, and further drives the hinge assembly 40 to act to drive the door body 30 to open and close the door. The door body 30 can be driven to open or close by the driving member 51 rotating forward or backward. It should be noted that the driving mechanism 50 of the present embodiment may be in driving connection with any one or more of the first to fourth pivot portions.

It can be understood that the rotation rule of the pivoting portion when the driving mechanism 50 drives the pivoting portion to rotate is the same as the rotation rule of the pivoting portion when the user manually opens and closes the door.

Further, in view of the fact that the door 30 has enough space for installing the driving mechanism 50, and that the door 30 is convenient to conceal the driving mechanism 50, the driving mechanism 50 is prevented from being exposed to affect the overall appearance of the box device, and it is preferable that the driving mechanism 50 is installed on the door 30 in this embodiment. Correspondingly, the drive mechanism 50 is in driving connection with the second pivot portion 432 and/or the fourth pivot portion 442. In other words, the driving mechanism 50 may be in transmission connection with only the second pivot portion 432, or the driving mechanism 50 may be in transmission connection with only the fourth pivot portion 442, or the driving mechanism 50 may be in transmission connection with the second pivot portion 432 and the fourth pivot portion 442, respectively.

Further, when the door 30 is closed to the opening 22, the first swing link 43 is close to the target side 24 with respect to the second swing link 44. In other words, at this time, the second pivot portion 432 is closer to the target side 24 than the fourth pivot portion 442, that is, the fourth pivot portion 442 is located at the edge of the door 30, which has limited space, so the driving mechanism 50 is preferably in driving connection with the second pivot portion 432 in this embodiment, so that the driving mechanism 50 is disposed in the door 30 and the driving connection between the driving mechanism 50 and the hinge assembly 40 is maximally facilitated, as shown in fig. 10 and 11.

In one embodiment, the drive mechanism 50 further includes a bracket 52 and a coupling 53. In the case where the driving mechanism 50 is provided to the door body 30, the bracket 52 is provided to the door body 30, and the driving element 51 is provided to the bracket 52, that is, the driving element 51 is provided to the door body 30 via the bracket 52. And, the driving member 51 is drivingly connected to the second pivot portion 432 and/or the fourth pivot portion 442 via a coupling 53.

For the hinge adopting the conventional track design, the driving piece 51 such as the motor is difficult to realize the movement of the shaft lever along the track, namely, the conventional hinge is limited by the structural design of the hinge, and the door body 30 is difficult to automatically open and close. In the present embodiment, the hinge assembly 40 adopts a swing rod design, and the driving member 51 such as a motor can easily swing the swing rod, so that the hinge assembly 40 in this embodiment can adapt to the driving mode of the driving mechanism 50, thereby being beneficial to realizing automatic door opening and closing of the door body 30.

In an embodiment, the case device may further include a damping element (not shown). Any one or more of the first to fourth pivoting portions described in the above embodiments may be provided with a damping element to increase the damping force received during rotation of the pivoting portion.

The present embodiment achieves the stop-and-go function of the door body 30 by the damping element. Specifically, the damping force provided by the damping element can keep the door body 30 stopped at the current position when the door body 30 hovers at an arbitrary angle during the rotation of the door body 30. And when a user or the above-described driving mechanism 50 applies a sufficient driving force to the door body 30, the driving force overcomes the damping force, so that the door body 30 resumes rotation.
