[0043] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] The terms used in this embodiment, such as "upper", "above", "lower", "below", etc., to indicate relative positions in space are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms of relative positions in space may be intended to include different orientations of the device when it is in use or working other than the orientation shown in the drawings. For example, "upper", "lower", "left", "right", "horizontal", and "vertical" in this embodiment are all relative positions in space when the refrigerator is in normal use.

[0045] The terms first, second, third, fourth, etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated; in addition, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, the connection can be a direct connection or an indirect connection through an intermediate medium, and can be a fixed connection or a movable connection or a detachable connection or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will be combined with the attached embodiment of the present invention. Figure 1 -8. Provide a clear and complete description of the technical solutions in the implementation mode of the utility model.

[0047] An embodiment of the utility model provides a refrigerator, referring to Figure 1 and Figure 2 The refrigerator includes a box body 60, a door body 50, and a hinge mechanism. The hinge mechanism is connected between the box body 60 and the door body 50, and the door body 50 can be opened or closed.

[0048] In a specific embodiment, the above-mentioned refrigerator is a built-in upright refrigerator, but of course, it is not limited to this.

[0049] The door body 50 includes an inner lining 501, a glass panel 503, and an insulation layer 502 disposed between the inner lining 501 and the glass panel 503. Preferably, the hinge mechanism is connected to the insulation layer 502, and when the hinge mechanism is subjected to external force, the insulation layer 502 supports and buffers the hinge mechanism and does not touch the glass panel 503, so as to prevent the glass panel 503 from being damaged.

[0050] In the present invention, the hinge mechanism is installed on the top surface of the thermal insulation layer 502. Preferably, a connecting plate 504 is installed on the top surface of the thermal insulation layer 502, and the hinge mechanism is installed on the connecting plate 504.

[0051] Reference Figure 4 -8. The hinge mechanism provided by the present invention is specifically a folding hinge mechanism. The hinge mechanism can achieve the above-mentioned installation requirements, and can be installed in a refrigerator or freezer, or in other household appliances or furniture, and the present invention does not make any specific restrictions.

[0052] Specifically, refer to Figure 3 -5, the hinge mechanism includes a fixed seat 10, a movable seat 20 and a connecting rod assembly 30 connected between the fixed seat 10 and the movable seat 20.

[0053] The fixed seat 10 is used to be fixedly connected to the box body 60, and the movable seat 20 is used to be fixedly connected to the door body 50. Specifically, the movable seat 20 is fixedly connected to the connecting plate 504 and the insulation layer 502. The movable seat 20 has a folded state that is closed compared to the fixed seat 10, and an open state that is pivoted and opened compared to the fixed seat 10. When the movable seat 20 is in the folded state, the door body 50 is closed to the box body 60. When the movable seat 20 switches from the folded state to the open state, under the action of the connecting rod assembly 30, the movable seat 20 drives the door body to rotate and open along a preset trajectory.

[0054] Reference Figure 6 The fixed seat 10 includes a fixed portion 101 and two third supporting portions 102 connected to the same side of the fixed portion 101. The fixed portion 101 and the two third supporting portions 102 enclose a second mounting groove 103. When the movable seat 20 is in the folded state, part of the connecting rod assembly 30 is located in the second mounting groove 103.

[0055] The fixing part 101 is provided with a fixing hole 104, and the fixing part 101 can be installed on the box body 60 by passing fasteners such as screws and bolts through the fixing hole 104. Preferably, the fixing part 101 extends vertically and is fixed to the front surface of the box body 60, which is convenient for installation.

[0056] The two third support portions 102 are parallel to each other and extend substantially in the horizontal direction, so that the second mounting slot 103 is open toward the movable seat 20 in the horizontal direction, which facilitates the folding and unfolding of the connecting rod assembly 30 .

[0057] Reference Figure 6 and Figure 7 The movable seat 20 includes a connecting portion 201 and a mounting portion 202, a first supporting portion 203, and a second supporting portion 204 connected to the same side of the connecting portion 201. The connecting portion 201, the first supporting portion 203, and the second supporting portion 204 enclose a first mounting groove 206. When the movable seat 20 is in the folded state, part of the connecting rod assembly 30 is located in the first mounting groove 206.

[0058] The mounting portion 202 is provided with a mounting hole 207, and the mounting portion 202 can be fixed to the connecting plate 504 by passing through the mounting hole 207 with fasteners such as screws and bolts. The fasteners on the mounting portion 202 pass through the connecting plate 504 and extend into the thermal insulation layer 503. The mounting portion 202 extends in the horizontal direction, and the mounting hole 207 and the fasteners used to mount the movable seat 20 are parallel to the glass panel 503. When the refrigerator is bumped, the foam material in the thermal insulation layer 502 can play a buffering and supporting role, and the movable seat 20 and the fasteners used to mount the movable seat 20 are not easy to deform. Even if the movable seat 20 or the fasteners are slightly deformed, the displacement and stress caused by the deformation can be released by the foam material and will not act on the door body 50, so the glass panel 503 is not easy to be damaged.

[0059] The mounting portion 202 , the first supporting portion 203 , and the second supporting portion 204 are parallel to each other and extend substantially in a horizontal direction, so that the first mounting slot 206 is open toward the fixing seat 10 , which facilitates the folding and unfolding of the connecting rod assembly 30 .

[0060] Reference Figure 6 and Figure 7 , the portion of the connecting portion 201 located in the region of the mounting portion 202 extends toward the thermal insulation layer 502, so that the distance between the mounting portion 202 and the first supporting portion 203 is greater than the distance between the second supporting portion 204 and the first supporting portion 203. With such a configuration, the mounting portion 202 is closer to the thermal insulation layer 502 during installation, making the connection between the mounting portion 202 and the thermal insulation layer 502 more stable. In addition, when the movable seat 20 is folded, a gap is left between the connecting rod assembly 30 and the mounting portion 202 to avoid the fasteners, preventing the fasteners from interfering with the connecting rod assembly 30, thereby ensuring the smooth operation of the entire hinge mechanism.

[0061] A step portion 205 is connected between the mounting portion 202 and the second supporting portion 204 . The step portion 205 is inclined to play a connecting transition role, thereby increasing the overall strength of the movable seat 20 .

[0062] The width of the mounting portion 202 is greater than that of the first supporting portion 203 , so that the connection area between the movable seat 20 and the thermal insulation layer 50 is larger, thereby ensuring the stability of the connection and increasing the overall strength of the movable seat 20 , making the movable seat 20 less likely to deform.

[0063] A recess is formed at a position of the first support portion 203 corresponding to the mounting portion 202 , and the mounting hole 207 is located within the projection range of the recess, so as to facilitate fixing of fasteners when the movable seat 20 is installed.

[0064] Reference Figure 4 and Figure 5 The connecting rod assembly 30 includes a first connecting rod 301, a second connecting rod 302, a third connecting rod 303 and a fourth connecting rod 304. The two ends of the first connecting rod 301 are rotatably connected to the movable seat 20 and the second connecting rod 302 respectively. One end of the second connecting rod 302 is rotatably connected to the fixed seat 10, and the other end is rotatably connected to the first connecting rod 301. One end of the third connecting rod 303 is rotatably connected to the movable seat 20, and the other end is rotatably connected to the second connecting rod 302. One end of the fourth connecting rod 304 is rotatably connected to the fixed seat 10, and the other end is rotatably connected to the third connecting rod 303. Thus, the first connecting rod 301, the second connecting rod 302, the third connecting rod 303, the fourth connecting rod 304 and the movable seat 20 form a multi-connecting rod structure, so that the refrigerator door body 50 is switched between the folded state and the opened state.

[0065] Reference Figure 4 and Figure 5 The first link 301 and the movable seat 20 are rotatably connected to the first pivot axis 30a, and the third link 303 and the movable seat 20 are rotatably connected to the second pivot axis 30b. The first link 301 and the second link 302 are rotatably connected to the third pivot axis 30c, and the third link 303 and the second link 302 are rotatably connected to the fourth pivot axis 30d. The lines connecting the first pivot axis 30a, the second pivot axis 30b, the third pivot axis 30c, and the fourth pivot axis 30d enclose a quadrilateral.

[0066] Reference Figure 4 and Figure 5 , the second link 302 and the fixing base 10 are rotatably connected to the fifth pivot axis 30e, the fourth link 304 and the fixing base 10 are rotatably connected to the sixth pivot axis 30f, and the fourth link 304 and the third link 303 are rotatably connected to the seventh pivot axis 30g. The connecting lines of the fourth pivot axis 30d, the fifth pivot axis 30e, the sixth pivot axis 30f, and the seventh pivot axis 30g also enclose a quadrilateral. The structural combination of the two quadrilaterals enables the hinge mechanism to run according to a preset trajectory and smoothly switch between the folded state and the opened state.

[0067] Reference Figure 4 and Figure 5 When the hinge mechanism is in the folded state, the first link 301 and the third link 303 are close to each other. In the process of switching the hinge mechanism from the folded state to the open state, the end of the third link 303 facing the movable seat 20 gradually approaches the middle position of the opposite ends of the first link 301. The first link 301 is provided with an avoidance groove 3011 corresponding to the end of the third link 303 on the side facing the third link 303. When the hinge mechanism is in the open state, the end of the third link 303 can be engaged with the avoidance groove 3011. The structure of the hinge mechanism is more compact, saving installation space.

[0068] Reference Figure 8 A first receiving groove 3021 is formed on the second connecting rod 302, the height of the first connecting rod 301 and the third connecting rod 303 is less than the height of the second connecting rod 302, and the first connecting rod 301 and the third connecting rod 303 are rotatably connected in the first receiving groove 3021. In the folded state, part of the structure of the first connecting rod 301 and the third connecting rod 303 is folded and stored in the first receiving groove 3021, so that the connecting rod assembly 30 is more compact in the folded state, saving installation space.

[0069] Reference Figure 8The fourth connecting rod 304 includes a first pivoting portion 3041 rotatably connected to the fixing seat 10, a second pivoting portion 3042 rotatably connected to the third connecting rod 303, a first engaging portion 3043, and a second engaging portion 3044. The first engaging portion 3043 and the second engaging portion 3044 are located between the first pivoting portion 3041 and the second pivoting portion 3042. The first engaging portion 3043 extends from the first pivoting portion 3041 to the second pivoting portion 3042 and is connected to the second engaging portion 3044.

[0070] The thickness of the first engaging portion 3043 is greater than the overall thickness of the third connecting rod 303 and less than the height of the second mounting groove 103. The third connecting rod 303 is formed with a second receiving groove 3031, and the thickness of the second engaging portion 3044 is less than the height of the second receiving groove 3031. When the hinge mechanism is in the folded state, the first engaging portion 3043 is engaged in the second mounting groove 103, and the second engaging portion 3044 is engaged in the second receiving groove 3031. The structure of the hinge mechanism in the folded state is more compact, which greatly reduces the required installation space.

[0071] The movable seat 20 in the hinge mechanism provided by the utility model is installed from top to bottom, so when the hinge mechanism is connected to the refrigerator, the fasteners used to fix the movable seat 20 are parallel to the glass panel 503, and the movable seat 20 is fixedly connected to the insulation layer 502. When the refrigerator is bumped, if the hinge mechanism and the fasteners are deformed, there is space between the fasteners and the glass panel 503 for deformation, and the deformation amount will be directly transmitted to the insulation layer 502. Under the buffering and supporting effect of the foaming material, the glass panel 503 is not easily damaged.

[0072] Furthermore, the connecting rod assembly 30 in the hinge mechanism has a relatively compact structure, so that the overall volume of the hinge mechanism after folding is relatively small, which greatly saves the installation space required for the hinge mechanism and saves production costs.

[0073] As a preferred solution of this embodiment, the fixing seat 10, the mounting seat 20, the first connecting rod 301, the second connecting rod 302, the third connecting rod 303, and the fourth connecting rod 304 are all made of bent metal plates, but of course, this is not limited to this.

[0074] Reference Figure 2 and Figure 3 The refrigerator further includes a wiring mechanism 40, and the hinge mechanism is arranged below the wiring mechanism 40. The installation position of the hinge mechanism is closer to the insulation layer 502, so that the installation of the hinge mechanism and the door body 50 is more stable.

[0075] In other embodiments, the wiring mechanism 40 may also be disposed below the hinge mechanism. As long as the movable seat 20 is installed from top to bottom and is connected to the insulation layer 502 , the specific structure and position are not limited.

[0076] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
