The hinge device includes a hinge base 10, a reinforcing plate 20, and an adjusting assembly.

The hinge base 10 includes a hinge portion 101, where the hinge portion 101 is of a plate structure and is configured with a first hollow portion 102, and the hinge base 10 is used to connect to the case 90. The hinge base 10 further includes a rolling portion 104, the rolling portion 104 and the hinge portion 101 are integrally formed, and the rolling portion 104 is disposed at the bottom of the case 90 and detachably connected to the case 90. The rolling part 104 is provided with rollers 105 for supporting the refrigerator and assisting the refrigerator to move and carry, thereby saving manpower.

The reinforcing plate 20 is detachably connected to the hinge portion 101, and is configured with an oblong hole 201, and the reinforcing plate 20 is used to connect the lower door body 100. The reinforcing plate 20 is connected with the hinge base 10 such that the lower door body 100 is connected with the case 90. It should be noted that, the reinforcing plate 20 is detachably connected to the hinge portion 101, and is not meant to be fixedly connected and not movable therebetween. In this embodiment, the reinforcing plate 20 and the hinge 101 can move relative to each other.

The reinforcing plate 20 is located above the hinge 101 and abuts against the plate surface of the hinge 101. The hinge part 101 carries the reinforcing plate 20, and the purpose of supporting the lower door body 100 by the hinge base 10 is achieved.

The adjusting component comprises an eccentric column 30, and the eccentric column 30 penetrates through the first hollowed-out portion 102 and the oblong hole 201. In the case of rotating the eccentric post 30, the eccentric post 30 pushes the reinforcing plate 20 to move in the first direction relative to the hinge base 10 to adjust the relative position of the lower door 100 with respect to the case 90 in the first direction.

Through the eccentric setting of eccentric post 30, under the circumstances of rotatory eccentric post 30, the lateral wall of one side of eccentric post 30 offsets with the pore wall of slotted hole 201 correspondence side to exert effort and promote reinforcing plate 20 and remove, reinforcing plate 20 is movable relative hinge seat 10, thereby realize the relative movement of reinforcing plate 20 and hinge seat 10 through adjusting the subassembly, adjust the position of reinforcing plate 20 relative box 90 along first direction, in other words, adjust the relative position of lower door body 100 and box 90, solve the problem of door body misalignment, improve the outward appearance of refrigerator.

In the present embodiment, the reference to the first direction is understood as a front-rear direction, and is also understood as a left-right direction. In case that the first direction is the front-rear direction, i.e., facing the refrigerator, the displacement of the lower door body 100 forward or backward is regulated by the hinge device, solving the problem of the misalignment of the lower door body 100 in the front-rear direction.

In this embodiment, the displacement of the lower door body 100 in the first direction is fine-tuned, so that the case body 90 and the lower door body 100 are flush with each other under the condition of ensuring the connection stability between the hinge device and the case body 90 and the lower door body 100, the problem of misalignment of the door body is solved, and the user experience is improved.

By adopting the hinge device provided by the embodiment of the disclosure, the hinge device is used for the bottom of the lower door body 100 of the refrigerator so as to adjust the problem of misalignment of the bottom of the lower door body 100; the relative positions of the reinforcing plate 20 and the hinge base 10 are adjusted by rotating the eccentric column 30, so that the relative positions of the lower door body 100 and the box body 90 along the first direction are adjusted, the problem of door misalignment is solved, and the appearance of the refrigerator is improved.

Optionally, the hinge portion 101 further includes a second hollow portion 103, and a bending portion 202 is configured at an edge of the reinforcing plate 20, where the bending portion 202 is inserted into the second hollow portion 103 to install and define a relative position of the reinforcing plate 20 and the hinge portion 101. The reinforcing plate 20 is inserted into the second hollowed-out portion 103 of the hinge portion 101 through the bending portion 202, so that the reinforcing plate 20 and the hinge portion 101 are relatively fixed.

The reinforcing plate 20 is located above the hinge portion 101, and the bending portion 202 is bent downward. In this way, when the bending portion 202 is inserted into the second hollowed portion 103, the connection stability between the reinforcing plate 20 and the hinge portion 101 can be improved.

The hollowed area of the second hollowed portion 103 is larger than the cross-sectional area of the bending portion 202, so that the bending portion 202 moves in the second hollowed portion 103 when the reinforcing plate 20 moves relative to the hinge base 10.

The hollowed area of the second hollowed portion 103 is larger than the cross-sectional area of the bent portion 202, and particularly when the reinforcing plate 20 moves relative to the hinge base 10, the bent portion 202 moves in the second hollowed portion 103 along the first direction.

Optionally, the eccentric post 30 includes: the eccentric part comprises a first boss 301 and a second boss 302 which are eccentrically arranged, the first boss 301 is arranged in the oblong hole 201, the second boss 302 is arranged in the first hollowed-out part 102, and the outer side wall of the second boss 302 is abutted against the first hollowed-out part 102.

Alternatively, the first boss 301 has a cylindrical shape. Optionally, the second boss 302 is cylindrical.

The first boss 301 and the second boss 302 are arranged eccentrically, i.e. the axis of the first boss 301 and the axis of the second boss 302 are arranged parallel and not collinear.

The second boss 302 is disposed on the first hollow portion 102, and the outer sidewall abuts against the first hollow portion 102. In this way, when the second boss 302 is inserted into the first hollow portion 102, the connection stability between the eccentric post 30 and the hinge portion 101 can be improved.

The first boss 301 is provided in the oblong hole 201, and a part of the outer side wall of the first boss 301 abuts against the wall of the oblong hole 201.

In the initial state, the symmetrical dividing line of the eccentric part and the long axis of the oblong hole 201 are arranged in a collinear manner; at this time, part of the outer side wall of the first boss 301 is abutted against the hole wall of the oblong hole 201. In the case of rotating the eccentric post 30, the sidewall of the first boss 301 abuts against the hole wall of the oblong hole 201 to push the reinforcing plate 20 to move, and drives the lower door body 100 to move along the first direction relative to the case 90, so as to adjust the displacement of the lower door body 100 in the first direction.

Illustratively, as shown in connection with fig. 2, the first direction of the present embodiment is the front-rear direction of the refrigerator. That is, the adjustment assembly adjusts the displacement of the lower door body 100 in the front-rear direction, thereby ensuring that the lower door body 100 of the refrigerator is flush with the case 90 and the adjacent lower door bodies 100 in the front-rear direction.

In practical use, the hinge mount 10 and the reinforcing plate 20 in the present embodiment are disposed laterally. The eccentric column 30 is vertically disposed.

In the case that the first direction is the front-rear direction of the refrigerator, the symmetrical parting line of the eccentric portion is laterally set to an initial state in which the eccentric portion is rotated rearward, and the reinforcing plate 20 is moved rearward in the first direction, thereby driving the lower door body 100 to be moved rearward in the first direction. In the initial state, the eccentric portion rotates forward, and the reinforcing plate 20 moves forward in the first direction, thereby driving the lower door body 100 to move forward in the first direction.

Wherein, no matter the eccentric wheel rotates backwards or forwards, the rotation angle is at most 90 degrees. The distance of movement of the reinforcing plate 20 and the lower door body 100 depends on the eccentric distance of the eccentric portion.

When the first boss 301 abuts against the hole wall of the oblong hole 201 and pushes the reinforcing plate 20 to move relative to the box body 90, and the reinforcing plate 20 is shifted to other directions, at this time, the bending portion 202 of the reinforcing plate 20 is inserted into the second hollowed-out portion 103 of the hinge portion 101, so that not only can the reinforcing plate 20 be relatively fixed to the hinge portion 101, but also the reinforcing plate 20 can be limited to rotate relative to the hinge portion 101, and the reinforcing plate 20 can be intelligently translated under the pushing action of the first boss 301.

Alternatively, the long axis of oblong hole 201 is disposed perpendicular to the first direction.

Optionally, the vertical plane where the long axis of the first oblong hole 201 is located is parallel to the plate surface of the door body.

Alternatively, the hinge housing 10 is connected to the lower door body 100 by the hinge shaft 80, and the hinge shaft 80 is disposed vertically. The long axis of the oblong hole 201 is disposed perpendicular to the axis of the hinge shaft 80. Under the adjusting action of the adjusting component, the hinge device not only can limit the moving direction of the reinforcing plate 20 through the cooperation of the bending part 202 and the second hollowed part 103, but also can limit the rotation of the reinforcing plate 20 through the hinge shaft 80, so that the lower door body 100 translates along the first direction to prevent the lower door body 100 from shifting to other directions. Thus, the double-protection function is achieved, and the failure of any one structure is avoided.

Optionally, the side wall of the first boss 301 is configured with an annular groove 3011 in the circumferential direction; the first boss 301 penetrates through the reinforcing plate 20 and partially protrudes from the upper plate surface of the reinforcing plate 20. The groove wall of the annular groove 3011 in this embodiment is located higher than the upper plate surface of the reinforcing plate 20 or is flush with the upper plate surface of the reinforcing plate 20.

The hinge device further includes: a spacer 40 which is inserted into the annular groove 3011 and abuts against the plate surface of the reinforcing plate 20 to fix the eccentric post 30; wherein the radius of the spacer 40 is larger than the minor diameter of the oblong hole 201.

When the eccentric post 30 is inserted into the oblong hole 201 of the reinforcing plate 20, the spacer 40 is fitted into the annular groove 3011, and the end surface area of the spacer 40 is larger than the cross-sectional area of the oblong hole 201. Thus, the spacer 40 can stop the eccentric post 30 from being removed from the oblong hole 201 of the reinforcing plate 20, thereby achieving the purpose of fixing the eccentric post 30.

The radius of the spacer 40 is larger than the minor diameter of the oblong hole 201, and it is understood that the spacer 40 may protrude from the oblong hole 201 after being fitted in the annular groove 3011, and may abut against the upper plate surface of the reinforcing plate 20, thereby restricting and fixing the eccentric post 30.

To facilitate insertion of the spacer 40 into the annular groove 3011, one end of the spacer 40 is open, thus facilitating clamping of the spacer 40 into the annular groove 3011 of the first boss 301.

Optionally, the adjusting assembly further includes a first nut 50, the first nut 50 having an internal thread-free structure; the eccentric post 30 further includes: the adjusting portion 303 is coaxially disposed with the second boss 302, so that the second boss 302 rotates synchronously when the adjusting portion 303 rotates, and the cross-sectional area is larger than that of the second boss 302.

The cross-sectional area of the adjusting portion 303 is greater than that of the second boss 302, that is, the adjusting portion 303 cannot penetrate through the first hollow portion 102.

In the case that the second boss 302 is disposed through the first hollow portion 102 of the hinge portion 101, the adjusting portion 303 is blocked by the hinge portion 101 around the first hollow portion 102 and abuts against the lower surface of the hinge portion 101, so as to limit the length of the eccentric post 30 disposed through the first hollow portion 102. In addition, the adjustment portion 303 abuts against the hinge portion 101, and the stability of the connection between the eccentric post 30 and the hinge portion 101 can be improved, so that the eccentric post 30 is prevented from shaking.

Wherein, the outer side wall of the adjusting portion 303 is configured with a plurality of limiting planes 3031, and the first nut 50 is sleeved on the adjusting portion 303 and abuts against the limiting planes 3031; the first nut 50 is rotated, and the first nut 50 drives the adjusting portion 303 to rotate, so that the first boss 301 is driven to rotate to push the reinforcing plate 20 to move.

The first nut 50 is sleeved on the adjusting portion 303 and is matched with the adjusting portion 303, and the two limiting planes 3031 cannot rotate relatively, so that when the first nut 50 is rotated, the adjusting portion 303 also rotates, and further the second boss 302 and the first boss 301 are driven to rotate, so that the reinforcing plate 20 is pushed to move.

The plurality of limiting planes 3031 of the outer sidewall structure of the adjustment portion 303 may be disposed in a crossing manner or may be disposed in parallel.

By rotating the first nut 50, the first nut 50 drives the adjusting portion 303 to rotate, thereby driving the eccentric portion to rotate to push the reinforcing plate 20 to move. In practice, the user may rotate the first nut 50 by manually rotating the first nut 50 or by screwing the first nut 50 with a wrench.

Alternatively, the cross-sectional area of the adjusting portion 303 is larger than the cross-sectional area of the first hollow portion 102, that is, the adjusting portion 303 cannot penetrate through the first hollow portion 102. So that the end surface of the adjusting portion 303 abuts against the hinge portion 101 when the eccentric post 30 penetrates the hinge portion 101, the relative position of the eccentric post 30 and the hinge portion 101 is defined.

In the case that the eccentric post 30 is inserted into the first hollow portion 102 of the hinge portion 101, the adjusting portion 303 is blocked by the hinge portion 101 around the first hollow portion 102, and the rest of the adjusting portion 303 abuts against the lower surface of the hinge portion 101, so as to define the length of the eccentric post 30 inserted into the first hollow portion 102, that is, the relative position of the eccentric post 30 and the hinge portion 101. In addition, the adjustment portion 303 abuts against the hinge portion 101, and the stability of the connection between the eccentric post 30 and the hinge portion 101 can be improved, so that the eccentric post 30 is prevented from shaking.

Alternatively, the first boss 301, the second boss 302, and the adjustment portion 303 are integrally formed. Alternatively, the eccentric post 30 is a solid structure. Thus, the structural strength of the eccentric post 30 is facilitated to be ensured during the rotation of the eccentric post 30.

Alternatively, the outer sidewalls of the first boss 301, the second boss 302, and the adjustment portion 303 have no screw structure. On the one hand, the contact surfaces of the eccentric post 30, the reinforcing plate 20, the hinge part 101 and the first nut 50 are facilitated to be attached, so that dust is prevented from entering, and the smoothness of rotation is affected.

Optionally, the adjustment assembly further comprises a second nut 60, the eccentric post 30 further comprising: a threaded portion 304 that is screwed with the second nut 60; wherein the second nut 60 abuts against the first nut 50 to fix the first nut 50.

The second nut 60 is connected to the threaded portion 304 of the eccentric post 30 through the threads, the second nut 60 abuts against the first nut 50, and the relative fixation of the first nut 50 and the eccentric post 30 is achieved through the relative fixation of the second nut 60 and the eccentric post 30, so that the self-adjusting portion 303 of the first nut 50 can be prevented from sliding down under the action of gravity.

Optionally, the cross-sectional area of the adjusting portion 303 is larger than the cross-sectional area of the threaded portion 304, so as to prevent the first nut 50 from interfering with the threaded structure of the threaded portion 304 when being sleeved up from the threaded portion 304 of the eccentric post 30 to the adjusting portion 303. In addition, when the second nut 60 is screwed to the screw portion 304, the second nut 60 can be stopped by the adjusting portion 303, so that the screw connection length between the second nut 60 and the screw portion 304 can be ensured, and the connection stability and the firmness between the second nut 60 and the eccentric post 30 can be ensured.

Optionally, the hinge device further comprises: the base 70 is screw-coupled with the screw part 304 of the eccentric post 30 to support the eccentric post 30.

The base 70 is in threaded connection with the threaded portion 304 of the eccentric post 30, not only can play a role in supporting the eccentric post 30, but also indirectly supports the reinforcing plate 20 and the lower door body 100 through supporting the eccentric post 30, so that the lower door body 100 is prevented from falling under the action of gravity after being used for a period of time.

In the case of refrigerator use, the height of the hinge part 101 to the ground can be adjusted by adjusting the screw connection length between the base 70 and the screw part 304 of the eccentric post 30, thereby ensuring the stability of the refrigerator in use. Especially in the case of uneven ground, the adjusting effect is remarkable.

Optionally, the hinge device further comprises: a hinge shaft 80 for connecting the reinforcing plate 20 and the lower door body 100; wherein the hinge shaft 80 is inserted and screw-coupled with the reinforcing plate 20, so that the distance from the end of the hinge shaft 80 to the plate surface of the reinforcing plate 20 is adjusted by rotating the hinge shaft 80 to adjust the distance in the vertical direction of the lower door body 100.

The hinge shaft 80 is inserted into the lower door body 100, and when the hinge shaft 80 is rotated, no relative displacement occurs between the hinge shaft 80 and the lower door body 100.

The hinge shaft 80 is in threaded connection with the reinforcing plate 20, and when the hinge shaft 80 is rotated, the distance from the end of the hinge shaft 80 to the plate surface of the reinforcing plate 20 increases or decreases, thereby driving the distance from the lower door body 100 to the plate surface of the reinforcing plate 20 to increase or decrease, and realizing adjustment of the relative position of the lower door body 100 in the vertical direction.

Optionally, the hinge shaft 80 includes a socket section 802 and a screw section 803, the socket section 802 is socket-coupled to the lower door body 100, and the screw section 803 is screw-coupled to the reinforcing plate 20.

Optionally, a stop portion 801 is configured at the plugging section 802 of the hinge shaft 80, the stop portion 801 is formed to protrude outwards from an outer side wall of the hinge shaft 80, and the stop portion 801 abuts against the bottom of the lower door body 100. Optionally, stop 801 is located at the interface of plug section 802 and threaded section 803. In this way, on the one hand, the lower door body 100 can be supported by the stopper 801, i.e., the connection area of the lower door body 100 with the hinge shaft 80 can be increased. On the other hand, the stop portion 801 is located above the reinforcing plate 20 and abuts against the upper plate surface of the reinforcing plate 20, so that the hinge shaft 80 can be stopped from moving downwards excessively along the vertical direction, the supporting acting force of the reinforcing plate 20 on the hinge shaft 80 and the lower door body 100 through the stop portion 801 can be improved, the stability of the lower door body 100 in the using process is further improved, and the falling phenomenon is avoided.
