[0029] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0030] It should be understood that the terms used herein, such as "upper", "lower", "outer", "inner", etc., indicating spatial relative positions 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 drawings. The spatial relative position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0031] The present invention provides a refrigerator 100, see Figure 1 and Figure 2 As shown, the refrigerator 100 includes a cabinet 1, a door 2 for opening and closing the cabinet 1, and a hinge mechanism 300 connected between the cabinet 1 and the door 2, and the door 2 of the refrigerator 100 is opened and closed by the hinge mechanism 300.

[0032] For further information, see Figures 3 to 10 As shown, the hinge mechanism 300 includes a fixed seat 5 for mounting on the box body 1, a movable seat 6 for mounting on the door body 2, and a connecting rod assembly 7 connected between the fixed seat 5 and the movable seat 6. It is known that in the process of the door body rotating and opening, the movable seat 6 moves synchronously with the door body 2, and under the action of the connecting rod assembly 7, the movement trajectory of the door body 2 and the movable seat 6 can be controlled.

[0033] It can be understood that, in the refrigerator 100, the door body 2 and the box body 1 have a pivot side that is rotatably connected, and the pivot end 4 in the present invention is an end of the hinge mechanism 300 that is close to the pivot side after being installed in the refrigerator 100.

[0034] The connecting rod assembly 7 includes a first connecting rod 71, a second connecting rod 72, and a linkage rod 73 for driving the first connecting rod 71 and the second connecting rod 72 to move along a preset trajectory. It is known that during the rotation and opening process of the door body 2, driven by the linkage rod 73, the first connecting rod 71 and the second connecting rod 72 move along their respective preset trajectories to control the movement trajectories of the door body 2 and the movable seat 6.

[0035] Specifically, one end of the first connecting rod 71 is rotatably connected to the side of the fixed seat 5 away from the pivot end 4, and the other end is rotatably connected to the side of the movable seat 6 close to the pivot end 4. One end of the second connecting rod 72 is rotatably connected to the side of the fixed seat 5 close to the pivot end 4, and the other end is slidably connected to the side of the movable seat 6 away from the pivot end 4. The two ends of the linkage rod 73 are respectively connected to the first connecting rod 71 and the second connecting rod 72, so as to drive the first connecting rod 71 and the second connecting rod 72 to move according to a preset trajectory. The present invention can make the movable seat 6 move according to a preset trajectory when the movable seat 6 is rotated and opened relative to the fixed seat 5 through the first connecting rod 71, the second connecting rod 72 and the linkage rod 73 in the connecting rod assembly, so that when the hinge mechanism 300 of the present invention is applied to a refrigerator, the movement trajectory of the door body 2 can be controlled, the versatility of the refrigerator 100 is improved, and the refrigerator 100 will not interfere with the cabinet when the door body 2 is opened even in an embedded application scenario, and the opening degree of the door body 2 can be guaranteed.

[0036] It can be understood that the movable seat 6 of the hinge mechanism 300 has an open state and a closed state. When the movable seat 6 is in the open state, the door body 2 is also in the open state. When the movable seat 6 is in the closed state, the door body 2 is also in the closed state. Figure 4 is a schematic structural diagram of the hinge mechanism 300 when the movable seat 6 is in an open state. Figure 6 , Figure 8 and Fig. 9 Schematic diagram of the structure of the hinge mechanism in the closed state of the movable seat. In the present invention, the movable seat 6 is driven to switch between the open state and the closed state by the movement of the connecting rod assembly 7, with the pivot end 4 as the rotation center. Specifically, the connecting rod assembly 7 has an unfolded state and a folded state. When the connecting rod assembly 7 is in the unfolded state, the movable seat 6 is in the open state. When the connecting rod assembly 7 is in the folded state, the movable seat 6 is in the closed state.

[0037] Furthermore, the door body 2 of the refrigerator 100 in the present invention has an end cover at one end close to the hinge mechanism 300, and the movable seat 6 is integrally arranged with the end cover, which not only simplifies the installation steps of the hinge mechanism 300, but also increases the overall strength of the movable seat 6.

[0038] Furthermore, when the door body 2 rotates and opens to the second stage after the first stage, the connecting rod assembly 7 is used to drive the movable seat 6 to drive the door body 2 to rotate in place. After the door body 2 moves forward, the door body 2 is ensured to rotate in place. Even if the refrigerator 100 is placed in a deep and narrow space, such as the application scenario of the built-in refrigerator 100, the door body 2 can be prevented from interfering with the surrounding objects, and the opening range of the door body 2 is further increased, which is convenient for users to take and put items in the refrigerator 100, thereby improving the user experience. It can be understood that the first stage and the second stage are not limited to two stages that occur continuously.

[0039] Furthermore, the movable seat 6 is provided with a slide groove 8, see Figure 6 For the sake of clarity, Figure 6 The structure of the movable seat is hidden in the figure, and the second connecting rod 72 is provided with a sliding shaft 9 that cooperates with the sliding groove 8. Through the cooperation between the sliding groove 8 and the sliding shaft 9, the second connecting rod 72 is slidably connected to the movable seat 6. It can be understood that the sliding groove 8 can be integrally provided with the movable seat 6, or can be embedded on the end surface of the movable seat 6.

[0040] Further, see Figure 7 As shown, the slide slot 8 includes a first guide arc segment 81 away from the side of the pivot end 4 and a second guide segment 82 close to the side of the pivot end 4; the first guide arc segment 81 includes a starting end 811 away from the second guide segment 82 and a terminal end 812 close to the second guide segment 82. When the slide shaft 9 is located at the starting end 811, the door body 2 is in a closed state. The sliding of the slide shaft 9 from the starting end 811 to the terminal end 812 is the first stage of the door body 2 rotating and opening from the closed state. The connecting rod assembly 7 drives the movable seat 6 to drive the door body 2 to move forward, so that the connecting rod assembly 7 can open and close the movable seat 6 in a smaller space while ensuring the opening range of the movable seat 6. It can be understood that the terminal end 812 of the first guide arc segment 81 is connected to the second guide end.

[0041] Furthermore, when the sliding shaft 9 is located at the end of the second guide segment 82 away from the first guide arc segment 81, the door body 2 is in a maximum open state.

[0042] In a specific embodiment of the present invention, the process from closing to opening of the door body 2 is as follows: the sliding shaft 9 on the second connecting rod 72 first slides from the starting end 811 of the first guide arc segment 81 to the terminal end 812, so that the connecting rod assembly 7 first drives the door body 2 to move forward, and then the sliding shaft 9 on the second connecting rod 72 slides from the second guide segment 82 close to the terminal end 812 to the second guide segment 82 away from the terminal end 812, so that the connecting rod assembly 7 drives the door body 2 to rotate in situ, so that the connecting rod assembly 7 can open and close the movable seat 6 in a smaller space while ensuring the opening range of the movable seat 6; without affecting the opening range of the door body 2 of the refrigerator 100, it can also prevent the refrigerator 100 from being placed in a deep and narrow space, causing the door body 2 to interfere with other objects when opening the door, thereby avoiding damage to the surface of the door body 2 of the refrigerator 100, thereby improving the user experience.

[0043] Further, see Figure 8 and Fig. 9 As shown, for the sake of clarity, the structure of the movable seat is hidden in the figure, and Figure 8 and Fig. 9 At the same time, the structure of the slide slot 8 is hidden. The fixing seat 5 has a fixing portion 51 for fixing to the box body 1 and a connecting plate 52 for connecting to the connecting rod assembly 7; when the door body 2 is in a closed state, the first guide arc segment 81 extends from the starting end 811 to the direction close to the fixing portion 51, and the arc center of the first guide arc segment 81 is located at a side away from the fixing portion 51; the second guide segment 82 extends from the terminating end 812 to the direction close to the fixing portion 51.

[0044] In the vertical direction, the first connecting rod 71, the linkage rod 73 and the second connecting rod 72 are staggered so that when the connecting rod assembly 7 moves, there is no interference between the first connecting rod 71, the linkage rod 73 and the second connecting rod 72. At the same time, when the movable seat 6 is in the closed state, the connecting rod assembly 7 occupies a small space.

[0045] Furthermore, the first connecting rod 71 has a first linkage section 711 located on the side of the second connecting rod 72 away from the fixing portion 51 when the movable seat 6 is in the closed state, and one end of the linkage rod 73 is rotatably connected to the first linkage section 711, and the other end is rotatably connected to the second connecting rod 72.

[0046] Furthermore, the second connecting rod 72 has a second linkage section 721 located on the side of the first connecting rod 71 close to the fixed portion 51 when the movable seat 6 is in the closed state, and one end of the linkage rod 73 is rotatably connected to the second linkage section 721, and the other end is rotatably connected to the first connecting rod 71.

[0047] In a specific embodiment, one end of the linkage rod 73 is connected to the first linkage section 711 , and the other end is connected to the second linkage section 721 , so as to open and close the movable seat 6 in a smaller space while ensuring the opening range of the movable seat 6 .

[0048] Further, see Figure 5 As shown, the first connecting rod 71 includes a first connecting point 712 rotatably connected to the side of the fixed seat 5 away from the pivot end 4, and a second connecting point 713 rotatably connected to the side of the movable seat 6 close to the pivot end 4; the second connecting rod 72 includes a third connecting point 722 rotatably connected to the side of the fixed seat 5 close to the pivot end 4, and a fourth connecting point 723 slidably connected to the side of the movable seat 6 away from the pivot end 4; when the movable seat 6 is in a closed state, refer to Figure 4 As shown, the third connection point 722 is located on the side of the second connection point 713 away from the fixed portion 51, so that the connecting rod assembly 7 is folded and stored between the fixed seat 5 and the movable seat 6. When the movable seat 6 is in a closed state, the occupied area of ​​the hinge mechanism 300 is reduced, thereby reducing the gap between the cabinet 1 and the door body 2 when the door body 2 of the refrigerator 100 is in a closed state.

[0049] It can be understood that the connecting plate 52 of the present invention is connected to the upper end of the fixing portion 51, and cantilevers vertically from the connection with the fixing portion 51 in a direction away from the fixing portion 51. When the door body 2 is closed, the projection of the connecting plate 52 in the vertical direction coincides with the door body 2.

[0050] Understandably, see Figure 4 As shown, when the movable seat 6 is in the open state, the third connection point 722 is located on a side of the second connection point 713 close to the fixing portion 51 .

[0051] In the present invention, when the movable seat 6 is converted from a closed state to an open state, the first connection point 712 and the third connection point 722 connected to the fixed seat 5 rotate in situ, and the second connection point 713 and the fourth connection point 723 movably connected to the movable seat 6 move, and the first connecting rod 71 takes the first connection point 712 as the rotation center, and the second connecting rod 72 takes the third connection point 722 as the rotation center. Driven by the linkage rod 73, the second connection point 713 rotates from the side of the third connection point 722 close to the fixed portion 51 to the side of the third connection point 722 away from the fixed portion 51; accordingly, the fourth connection point 723 slidably connected to the movable seat 6 moves from one end close to the fixed portion 51 to the side away from the fixed portion 51, and at the same time moves to the side close to the pivot end 4, thereby increasing the distance between the door body 2 and the box body 1, so that the door body 2 will not interfere with external cabinets, etc. during the opening process.

[0052] Further, see Fig. 9 As shown, the first connecting rod 71 also includes an avoiding section 714 connected to the first linkage section 711, and the first connection point 713 is arranged on the avoiding section 714; when the movable seat 6 is in a closed state, along the direction close to the pivot end 4, the avoiding section 714 first extends obliquely toward the direction close to the fixed portion 51, and then extends obliquely toward the direction away from the fixed portion 51. When the movable seat 6 is closed, the structure of the avoiding section 714 can avoid interference between the first connecting rod 71 and the second connecting rod 72, and at the same time reduce the gap between the door body 2 and the box body 1.

[0053] When the movable seat 6 is in a closed state, the first linkage section 711 first extends horizontally in a direction close to the pivot end 4, and then extends obliquely toward the fixed seat 5 close to the pivot end 4, thereby further reducing the gap between the door body 2 and the box body 1 when the movable seat 6 is closed.

[0054] Further, when the movable seat 6 is in the closed state, refer to Fig.10 As shown, the second connecting rod 72 includes a third section 724 extending from the third connection point 722 toward the fixed portion 51, and a fourth section 725 extending from one end of the third section 724 away from the third connection point 722 toward the fixed portion 51, and the second linkage section 721 is arranged on the third section 724.

[0055] Specifically, the third section 724 includes a first arc section 7241 provided with the third connection point 722 and extending toward the fixed portion 51, and a first extension section 7242 connected to one end of the first arc section 7241 away from the third connection point 722 and extending horizontally; one end of the linkage rod 73 is connected to the connection between the first arc section 7241 and the first extension section 7242, and the other end is connected to the first connecting rod 71, so that the linkage rod 73 drives the first connecting rod 71 and the second connecting rod 72 to move according to a preset trajectory.

[0056] Furthermore, the first connecting rod 71 and the second connecting rod 72 are arranged on opposite sides of the connecting plate 52 in the vertical direction, and the linkage rod 73 is located between the first connecting rod 71 and the second connecting rod 72; the fixed seat 5 is recessed with a avoidance groove 53, and when the movable seat 6 is in a closed state, one end of the linkage rod 73 connected to the second connecting rod 72 is located in the avoidance groove 53. On the premise of ensuring the movement trajectory of the connecting rod assembly 7, the volume of the connecting rod assembly 7 in the folded state is further reduced, and the distance between the movable seat 6 and the fixed seat 5 is further reduced, thereby reducing the gap between the door body 2 and the box body 1 of the small refrigerator 100.

[0057] In a specific embodiment of the present invention, the first connecting rod 71 is located on the upper side of the linkage rod 73, and the second connecting rod 72 is located on the lower side of the linkage rod 73. It can be understood that the upper side of one end of the linkage rod 73 is connected to the first linkage section 711, and the lower side of the other end of the linkage rod 73 is connected to the second linkage section 721, so that when the connecting rod assembly 7 is in a folded state, there will be no interference between the first connecting rod 71, the second connecting rod 72, and the linkage rod 73.

[0058] It is understandable that, except for the hinge mechanism 300, the other structures of the refrigerator 100 follow the structure of the existing refrigerator, and will not be described in detail here.

[0059] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0060] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
