In the case where the fixing portion 102 is screwed to the case 50 by a screw or a bolt, the screw or the bolt penetrates the reinforcing plate 40 and presses the reinforcing plate 40 between the fixing portion 102 and the top of the case 50 by the fixing portion 102. Wherein, the size of the reinforcing plate 40 is matched with the fixing part 102, so that the whole aesthetic degree of the hinge device is ensured.

The fixing portion 102 has a plate-shaped structure, and when the fixing portion 102 is assembled with the reinforcing plate 40 and the box body 50, the plate surfaces between the adjacent components are bonded to ensure the stability after assembly.

Alternatively, the fixing portion 102 is configured with a first oblong hole 1021 and a first guide groove 1022, and the guide direction of the first guide groove 1022 coincides with the first direction. The first adjustment assembly includes: the first eccentric wheel 201 is disposed in the first oblong hole 1021, penetrates through the reinforcing plate 40, and is inserted into the top of the case 50. The first guide post 202 is provided on the reinforcing plate 40 and is inserted into the first guide groove 1022, and is slidable along the first guide groove 1022.

The portion of the first eccentric wheel 201 inserted into the fixing portion 102 and the case 50 and the portion of the first guide post 202 inserted into the fixing portion 102 may have a non-threaded outer side wall. Thus, on one hand, the processing is convenient, and on the other hand, the smooth degree of rotation and sliding is prevented from being influenced because the thread structure and the connected parts are blocked.

In the initial state, the symmetrical parting line of the first eccentric wheel 201 is arranged in line with the long axis of the first oblong hole 1021, at this time, the edge of the first eccentric wheel 201 is abutted against the hole wall of the first oblong hole 1021, under the condition of rotating the first eccentric wheel 201, the first eccentric wheel 201 is abutted against the hole wall of the first oblong hole 1021 to push the fixing part 102 to move relative to the box 50, and the fixing part 102 moves along the first direction through the guiding limit of the first guiding groove 1022 and the first guiding column 202, so that the rotating part 101 and the door 60 are driven to move along the first direction.

Illustratively, in the initial state, the first eccentric 201 rotates rightward, and the fixing portion 102 moves rightward along the first direction, thereby driving the door 60 to move rightward along the first direction. In the initial state, the first eccentric wheel 201 rotates leftwards, and the fixing portion 102 moves leftwards in the first direction, so that the door 60 is driven to move leftwards in the first direction.

The rotation angle may be at most 90 ° regardless of whether the first eccentric 201 rotates rightward or leftward. In addition, the moving distance of the fixing portion 102 and the door 60 depends on the eccentric distance of the first eccentric wheel 201 (i.e. the distance between the axis of the boss 2011 and the axis of the cylinder 2013).

When the first eccentric wheel 201 abuts against the hole wall of the first oblong hole 1021 and pushes the fixing portion 102 to move relative to the case 50, and the fixing portion 102 is biased in other directions, at this time, the first guide post 202 is inserted into the first guide groove 1022 to limit the rotation of the fixing portion 102 relative to the case 50, so that the fixing portion 102 can only translate under the pushing action of the first eccentric wheel 201.

In an initial state, the first guide post 202 is positioned at or near the center of the first guide groove 1022 such that the first guide post 202 slides leftwards or rightwards along the first guide groove 1022.

Optionally, the long axis of the first oblong hole 1021 is disposed perpendicular to the axis of the first guide slot 1022.

The long axis passing through the first oblong hole 1021 is disposed perpendicular to the axis of the first guide slot 1022, so that the hinge plate 10 and the door body 60 translate in the first direction under the adjustment of the first adjustment assembly, to prevent the door body 60 from being offset in other directions.

The long axis of the first oblong hole 1021 is arranged perpendicular to the first direction.

Optionally, the fixing portion 102 is configured with at least two first guide grooves 1022, and the two first guide grooves 1022 are respectively disposed at two ends along the long axis of the first oblong hole 1021.

In the case of including two first guide grooves 1022, by providing the two first guide grooves 1022 at both ends along the long axis of the first oblong hole 1021, respectively, when the first adjusting assembly adjusts the fixing portion 102 to move in the first direction with respect to the case 50, the positional guidance of both ends of the first oblong hole can be defined, so as to ensure that the fixing portion 102 moves in the first direction with respect to the case 50.

Wherein two first guide grooves 1022 are disposed in parallel. Illustratively, at least one first guide slot 1022 is disposed adjacent to the first oblong aperture 1021.

Optionally, two first guide grooves 1022 are provided at opposite edge regions of the fixing portion 102. In this way, when the fixing portion 102 moves along the first direction relative to the case 50, the two first guide grooves 1022 are matched with the first guide posts 202, so that the fixing portion 102 is ensured not to be deformed due to movement, and the whole fixing portion 102 translates along the first direction under the action of the first adjusting component, so as to drive the door 60 to move along the first direction relative to the case 50.

Optionally, the first eccentric 201 comprises: boss 2011 and post 2013. The cylinder 2013 is disposed at one end of the boss 2011, and an axis of the cylinder 2013 is parallel to and not collinear with an axis of the boss 2011, so as to form an eccentric structure of the first eccentric wheel 201.

The cylinder 2013 of the first eccentric wheel 201 is inserted into the box 50, and the edge of the boss 2011 is abutted against the hole wall of the first oblong hole 1021. The first eccentric wheel 201 rotates, the cylinder 2013 rotates relative to the box 50 in situ, and when the boss 2011 rotates, the hole wall of the boss 2011 abuts against the hole wall of the first oblong hole 1021 due to the eccentric arrangement between the boss 2011 and the cylinder 2013, and pushes the hole wall of the first oblong hole 1021, namely the fixing part 102 with the first oblong hole 1021 to move.

Referring to fig. 3, when the boss 2011 rotates rightwards from the symmetrical dividing line of the first eccentric wheel 201, that is, the axis of the boss 2011 rotates rightwards from the symmetrical dividing line of the first eccentric wheel 201, the boss 2011 pushes the fixing portion 102 to move rightwards, that is, the fixing portion 102 deflects rightwards relative to the box 50, so as to drive the rotating portion 101 and the door 60 to deflect rightwards relative to the box 50, and further adjust the displacement of the door 60 relative to the box 50, and ensure that the outer edge of the door 60 is flush with the outer edge of the box 50.

Referring to fig. 3, when the boss 2011 rotates leftwards from the symmetrical parting line of the first eccentric wheel 201, that is, the axis of the boss 2011 rotates leftwards from the symmetrical parting line of the first eccentric wheel 201, the boss 2011 pushes the fixing portion 102 to move leftwards, that is, the fixing portion 102 is offset leftwards relative to the box 50, so as to drive the rotating portion 101 and the door 60 to offset leftwards relative to the box 50, further realize adjustment of displacement of the door 60 relative to the box 50, and ensure that the outer edge of the door 60 is flush with the outer edge of the box 50.

Optionally, the boss 2011 is integrally formed with the post 2013.

Optionally, the outer diameter of boss 2011 is greater than the outer diameter of cylinder 2013; at the connection between the boss 2011 and the pillar 2013, the end surface of the boss 2011 covers the end surface of the pillar 2013.

The outer diameter of the boss 2011 is larger than that of the cylinder 2013, so that when the cylinder 2013 is inserted into the box 50, the outer edge of the boss 2011 is abutted against the hole wall of the first oblong hole 1021. In addition, at the connection position of the boss 2011 and the cylinder 2013, the end surface of the boss 2011 covers the end surface of the cylinder 2013, and the boss 2011 always covers the cylinder 2013 in the orthographic projection along the direction of the symmetrical parting line of the first eccentric wheel 201, so as to further ensure the abutting and pushing actions of the boss 2011 and the hole wall of the first oblong hole 1021 when the first eccentric wheel 201 rotates leftwards or rightwards.

Optionally, the other end face of the boss 2011 is configured with a countersink 2012, the countersink 2012 defining a fixed position of the eccentric to the rotary tool.

In this embodiment, the countersunk slot 2012 may be a cross slot, the rotating tool may be a screwdriver, and when the position of the door 60 needs to be adjusted, the user inserts the cross head of the screwdriver into the countersunk slot 2012, and rotates the first eccentric wheel 201, so that the cylinder 2013 rotates relative to the box 50. The boss 2011 of the first eccentric wheel 201 generates a pushing force to the hole wall of the first oblong hole 1021 along the first direction along with the rotation of the eccentric wheel, so that the hole wall of the first oblong hole 1021 drives the fixing part 102 to transversely translate, and the position of the hinge plate 10 relative to the box 50 is adjusted, in other words, the relative position of the door 60 and the box 50 is adjusted, and the problem of misalignment of the door 60 is solved.

In practical applications, the countersunk structure 2012 is not limited to a cross-shaped structure, and the rotating tool is not limited to a screwdriver, and the rotating tool may be a screwdriver.

Optionally, the fixing portion 102 is configured with a plurality of mounting holes 1025, and the mounting holes 1025 are used for threading the fasteners 80 to be in threaded connection with the case 50; wherein, the apertures of part of the mounting holes 1025 in the plurality of mounting holes 1025 are the same.

It should be noted that, the apertures of some of the mounting holes 1025 are the same in the plurality of mounting holes 1025, which is understood that not all of the mounting holes 1025 in the plurality of mounting holes 1025 have a uniform aperture, i.e., at least two apertures are included; it is also understood that the plurality of mounting holes 1025 unifies the aperture, i.e., only one aperture.

Whether there is only one aperture or two apertures, at least the mounting hole 1025 has an aperture that is larger than the aperture through which the fastener 80 is threaded into the housing 50. And, the distance from the hole wall of the mounting hole 1025 to the axis of the fastener 80 is greater than or equal to the moving distance of the fixing part 102 under the pushing of the eccentric wheel. In this way, the fixing portion 102 can be prevented from moving under the pushing of the eccentric wheel, so that the mounting hole 1025 is dislocated from the mounting position of the box 50, and the problem that the fastener 80 cannot be mounted can be avoided.

In the case of at least two apertures, for convenience of description and distinction, the fixing portion 102 includes at least two mounting holes 1025, which are a first mounting hole 1025 and a second mounting hole 1025, respectively, wherein the aperture of the first mounting hole 1025 is smaller than that of the second mounting hole 1025. The second mounting hole 1025 is a distance from the hole wall of the mounting hole 1025 to the axis of the fastener 80, which is greater than or equal to a moving distance of the fixing portion 102 under the pushing of the eccentric wheel.

Where the aperture of the first mounting hole 1025 is adapted to the outer diameter of the fastener 80. The first mounting hole 1025 may serve to temporarily define a position between the fixing portion 102 and the case 50 when the refrigerator is shipped. It should be noted that before rotating the eccentric wheel, the fastener 80 in the first mounting hole 1025 needs to be removed, so that the eccentric wheel can be rotated, and the fixing portion 102 is pushed to move relative to the case 50 by the rotating eccentric wheel, so as to adjust the position of the hinge plate 10 relative to the case 50, in other words, adjust the relative positions of the door 60 and the case 50, thereby solving the problem of misalignment of the door 60.

Optionally, the reinforcing plate 40 is configured with a first mounting groove 401, the bottom of the first mounting groove 401 is configured with a first hollow part 402 with an oblong shape, and the first hollow part 402 is used for penetrating the first eccentric wheel 201; the bottom area of the first mounting groove 401 is larger than the cross-sectional area of the first oblong hole 1021, and the cross-sectional area of the first oblong hole 1021 is larger than the hollowed-out area of the first hollowed-out portion 402.

The first mounting groove 401, the first hollow portion 402, and the first mounting groove 401, the first hollow portion 402 and the first oblong hole 1021 configured by the reinforcing plate 40 are defined in area, so that the reinforcing plate 40 can not only play a role in fixing the first guide post 202, but also can avoid interference with the rotation of the first eccentric wheel 201 under the condition of rotating the first eccentric wheel 201.

The position of the first hollowed-out portion 402 is matched with the position of the first oblong hole 1021, so that the first eccentric wheel 201 sequentially passes through the first oblong hole 1021 and the first hollowed-out portion 402 to be inserted into the top of the box 50. The boss 2011 of the first eccentric wheel 201 abuts against the upper edge of the first hollow portion 402 of the reinforcing plate 40, that is, the first eccentric wheel 201 is pressed against the reinforcing plate 40 area around the first hollow portion 402. Thus, the bottom area of the first mounting groove 401 is larger than the hollowed area of the first hollowed portion 402, so that interference between the first eccentric wheel 201 and the bottom wall of the first mounting groove 401 when the reinforcing plate 40 around the first hollowed portion 402 is pressed can be avoided.

And, neither the first eccentric wheel 201 rotates rightward nor leftward, interference with the side wall of the first mounting groove 401 occurs.

Alternatively, the fixing portion 102 is configured with a second oblong hole 1023 and a second guide slot 1024, and the guide direction of the second guide slot 1024 coincides with the second direction. The second adjustment assembly includes: the second eccentric wheel 301 is arranged in the second oblong hole 1023, penetrates through the reinforcing plate 40 and is inserted into the top of the box body 50; the second guide post 302 is provided in the case 50 and penetrates the reinforcing plate 40 and the second guide groove 1024, and is slidable along the second guide groove 1024.

The portion of the second eccentric wheel 301 inserted into the fixing portion 102 and the case 50 and the portion of the second guide post 302 inserted into the fixing portion 102 may have a non-threaded outer side wall. Thus, on one hand, the processing is convenient, and on the other hand, the smooth degree of rotation and sliding is prevented from being influenced because the thread structure and the connected parts are blocked.

In the initial state, the symmetrical parting line of the second eccentric wheel 301 is arranged in line with the long axis of the second oblong hole 1023, at this time, the edge of the second eccentric wheel 301 is abutted against the hole wall of the second oblong hole 1023, and under the condition of rotating the second eccentric wheel 301, the second eccentric wheel 301 is abutted against the hole wall of the second oblong hole 1023 to push the fixing part 102 to move relative to the box 50, and the fixing part 102 moves along the second direction through the second guide slot 1024 and the guide limit of the second guide post 302, so that the rotating part 101 and the door 60 are driven to move along the second direction.

Illustratively, in the initial state, the second eccentric 301 rotates counterclockwise, and the fixing portion 102 moves inward in the second direction (i.e., toward the housing cavity of the case 50 or may also be understood as a direction facing away from the user), thereby driving the door 60 to move inward in the second direction. In the initial state, the second eccentric wheel 301 rotates clockwise, and the fixing portion 102 moves outwards (opposite to inwards) along the second direction, so as to drive the door 60 to move outwards along the second direction.

The rotation angle may be at most 90 ° no matter whether the second eccentric 301 rotates clockwise or counterclockwise. In addition, the moving distance of the fixing portion 102 and the door 60 depends on the eccentric distance of the second eccentric wheel 301 (i.e. the distance between the axis of the boss 2011 and the axis of the cylinder 2013).

When the second eccentric wheel 301 abuts against the hole wall of the second oblong hole 1023 and the fixing portion 102 is pushed to move relative to the box 50, and the fixing portion 102 is biased in other directions, at this time, the second guide post 302 is inserted into the second guide slot 1024 to limit the fixing portion 102 to rotate relative to the box 50, so that the fixing portion 102 can only translate under the pushing action of the second eccentric wheel 301.

In an initial state, the second guide post 302 is positioned at or near the center of the second guide slot 1024 such that the second guide post 302 slides inwardly or outwardly (i.e., slides back and forth) along the second guide slot 1024.

Alternatively, the structure of the second eccentric 301 is the same as that of the first eccentric 201. That is, the second eccentric 301 also includes a boss 2011 and a post 2013. Other details about the boss 2011 and the post 2013 of the second eccentric 301 are not described herein, please refer to the description about the boss 2011 and the post 2013 of the first eccentric 201.

The first mounting hole 1025 and the fastener 80 penetrating through the first mounting hole 1025 are arranged between the first oblong hole 1021 and the second oblong hole 1023.

In addition, the second guide post 302 is provided not only to pass through the first guide groove 1022 but also to pass through the reinforcing plate 40. In this way, not only can the fixing portion 102 be moved in the second direction by the second guide post 302, but also the movement of the reinforcing plate 40 can be restricted.

Alternatively, the long axis of the second oblong hole 1023 is disposed perpendicular to the long axis of the second guide slot 1024.

The long axis passing through the second oblong hole 1023 is perpendicular to the axis of the second guide slot 1024, so that the hinge plate 10 and the door body 60 translate in the second direction under the adjustment of the second adjustment assembly, to prevent the door body 60 from being offset in other directions.

The long axis of the second oblong hole 1023 is arranged perpendicular to the second direction.

Optionally, a vertical plane where the long axis of the second oblong hole 1023 is located is disposed parallel to the plate surface of the door body 60.

Optionally, the fixing portion 102 is configured with at least two second guide grooves 1024, and the two second guide grooves 1024 are respectively disposed at two ends along the long axis of the second oblong hole 1023.

In the case of including two second guide grooves 1024, by disposing the two second guide grooves 1024 at both ends along the long axis of the second oblong hole 1023, respectively, when the second adjusting assembly adjusts the fixing portion 102 to move in the second direction relative to the case 50, the positional guidance of both ends of the second oblong hole can be defined to ensure that the fixing portion 102 moves in the second direction relative to the case 50.

Wherein two second guide slots 1024 are disposed in parallel. Illustratively, at least one second guide slot 1024 is disposed adjacent to the second oblong aperture 1023.

Optionally, two second guide grooves 1024 are provided at opposite edge regions of the fixing portion 102. In this way, when the fixing portion 102 moves along the second direction relative to the case 50, the two second guide grooves 1024 are matched with the second guide posts 302, so that the fixing portion 102 is guaranteed not to deform due to movement, and the whole fixing portion 102 translates along the second direction under the action of the second adjusting component, so as to drive the door 60 to move along the second direction relative to the case 50, thereby adjusting the position of the hinge plate 10 relative to the case 50, in other words, adjusting the relative positions of the door 60 and the case 50, and solving the problem of misalignment of the door 60.

Optionally, the reinforcing plate 40 is configured with a second mounting groove 403, and a second hollow portion 404 with an oblong shape is configured at the bottom of the second mounting groove 403, where the second hollow portion 404 is used to penetrate the second eccentric wheel 301; the bottom area of the second mounting groove 403 is larger than the cross-sectional area of the second oblong hole 1023, and the cross-sectional area of the second oblong hole 1023 is larger than the hollowed-out area of the second hollowed-out portion 404.

The second mounting groove 403, the second hollow portion 404, and the second oblong hole 1023 configured by the reinforcing plate 40 are defined in area, so that the reinforcing plate 40 can not only play a role in fixing the second guide post 302, but also can avoid interference with the rotation of the second eccentric wheel 301 in the case of rotating the second eccentric wheel 301.

The position of the second hollowed-out portion 404 is matched with the position of the second oblong hole 1023, so that the second eccentric wheel 301 sequentially passes through the second oblong hole 1023 and the second hollowed-out portion 404 and is inserted into the top of the box 50. The boss 2011 of the second eccentric wheel 301 abuts against the upper edge of the second hollow portion 404 of the reinforcing plate 40, that is, the second eccentric wheel 301 is pressed against the reinforcing plate 40 area around the second hollow portion 404. In this way, the bottom area of the second mounting groove 403 is larger than the hollowed area of the second hollowed portion 404, so that the second eccentric wheel 301 can be prevented from interfering with the bottom wall of the second mounting groove 403 when pressing the reinforcing plate 40 around the second hollowed portion 404.

And, neither the clockwise nor counterclockwise rotation of the second eccentric 301 is interfered with the sidewall of the second mounting groove 403.
