[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0051] Combination Figures 1 to 4 As shown, the embodiment of the present disclosure provides a refrigerator, including a box body 10 defining a storage space and at least one door assembly, wherein the storage space of the box body 10 can be further divided into a plurality of storage compartments to meet the storage requirements of different items. The door assembly includes a door body and a driving device. In this embodiment, the storage space of the box body 10 is opened or closed by driving the door body to move in translation through the driving device.

[0052] The door body 20 is arranged on the front side of the box body 10, and is used to open or close the storage space; the driving device includes a sliding assembly 30 and a connecting rod assembly 40 connected to each other, the sliding assembly 30 is arranged on the box body 10, and the connecting rod assembly 40 connects the door body and the sliding assembly 30, and the sliding assembly 30 drives the connecting rod assembly 40 to move, so as to drive the door body 20 to open or close the storage space by translational movement.

[0053] With the refrigerator provided in the embodiment of the present disclosure, the storage space of the refrigerator is opened or closed by driving the door body to move in translation through a driving device. The lateral translation opening method of the door body can not only make the refrigerator more compactly placed in the kitchen or other spaces, thereby improving space utilization, but also has good sealing performance, thereby reducing the extrusion damage to the refrigerator door seal and reducing the defective rate of the door seal.

[0054] The door body that moves laterally can be fully opened under the driving action of the driving device, so as to facilitate the storage and access of items. When the door body closes the storage space of the box body 10, the door body, the door seal and the box body 10 are evenly sealed, and the door seal is evenly stressed, so that the refrigerator has good sealing performance, can effectively maintain the temperature and humidity in the refrigerator, and improve the energy efficiency of the refrigerator. At the same time, due to its good sealing performance, the leakage of cold air can be reduced, thereby reducing energy waste.

[0055] The door seal of a refrigerator is one of the important parts of the refrigerator. It can ensure the sealing performance of the refrigerator, prevent the cold air from leaking out, and also play a role in heat preservation. The quality of the door seal directly affects the energy efficiency level and heat preservation effect of the refrigerator, so it is crucial for the normal operation of the refrigerator.

[0056] In this embodiment, the door body is arranged to be opened or closed in a translational manner, so that when closing the door, the pressure of the door body on the door seal can be reduced, thereby reducing the defective rate of the door seal and ensuring the sealing effect of the door seal.

[0057] The driving device drives the door body 20 to move in translation, wherein the driving device is arranged at the top and / or bottom of the door body 20, so that when the driving device is working, the door body moves to the left or right relative to the box body 10 to open the storage space of the box body 10. It should be noted that the driving device not only drives the door body to move, but also supports the door body to ensure that the door body moves in translation to open or close the storage space of the box body 10.

[0058] The driving device includes a sliding assembly 30 and a connecting rod assembly 40 that are connected to each other. The sliding assembly 30 is arranged on the box body 10. The connecting rod assembly 40 connects the door body and the sliding assembly 30. The sliding assembly 30 drives the connecting rod assembly 40 to move. During the movement, the connecting rod assembly 40 drives the door body to move in translation through different movement paths of each connecting rod to open or close the storage space of the box body 10.

[0059] In some embodiments, the driving device is disposed on the top of the box 10. The top of the box 10 has sufficient installation space to install the driving device, and the driving device disposed on the top of the box 10 also serves the purpose of hanging the door body.

[0060] Optionally, the sliding assembly 30 includes: a driving motor 301, which is arranged on the top of the box 10; a linear motion device, which is connected to the driving motor 301, and the driving motor 301 drives the linear motion device to perform linear motion, and moves back and forth in a straight line in a direction parallel to the door body.

[0061] The driving motor 301 works to drive the linear motion device to perform linear reciprocating motion, wherein the motion trajectory of the linear motion device is parallel to the door body.

[0062] In some embodiments, the linear motion device may include a ball screw pair structure formed by a screw and a nut. The nut is sleeved on the screw and connected to the connecting rod assembly 40, and the screw is connected to the drive motor 301. The screw rotates under the action of the drive motor 301, and the nut moves linearly along the screw, thereby driving the connecting rod assembly 40 to move.

[0063] In some embodiments, the linear motion device may include a gear and rack 303 structure formed by a gear 302 and a rack 303, the gear 302 is meshed and connected with the rack 303, the gear 302 is meshed and connected with the rack 303, the gear 302 rotates under the action of the drive motor 301, meshes with the rack 303 for transmission, and the rack 303 moves linearly along the transmission direction, thereby driving the connecting rod assembly 40 to move.

[0064] Optionally, the linear motion device includes: a gear 302, connected to the driving motor 301; a rack 303, having a plurality of gear teeth, the rack 303 is slidably arranged on the top of the box body 10, and is arranged in a direction parallel to the door body; a rotating motor 304, arranged on the rack 303 and avoiding the gear tooth arrangement; wherein the rotating motor 304 is drivingly connected to the connecting rod assembly 40 to drive the connecting rod assembly 40 to rotate.

[0065] The gear 302 is placed flat on the top of the box 10. The gear 302 is not only connected to the driving motor 301, but also meshed with the rack 303. The rack 303 is slidably connected to the top of the box 10, so that the stability of the rack 303 during movement can be ensured. The driving motor 301 drives the gear 302 to rotate, and the rack 303 meshed with the gear 302 is forced to move in a straight line, driving the connecting rod assembly 40 to move, thereby driving the door body to move in translation.

[0066] The rack 303 is arranged near the door body. The rack 303 provided in this embodiment has a certain width so as to be connected with the connecting rod assembly 40. The connecting rod assembly 40 is connected to the upper surface of the rack 303. In some embodiments, the rack 303 is stepped, and the thickness of the rack 303 on the side where the gear teeth are located is greater than the thickness of the rack 303 connected with the connecting rod assembly 40. In this way, after the connecting rod assembly 40 is connected with the rack 303, the height of the linear motion device is reduced, thereby avoiding affecting the overall height and appearance of the refrigerator.

[0067] Optionally, the length of the rack 303 matches the width of the door body, ensuring that the door body 20 can fully open the storage space under the movement trajectory of the rack 303.

[0068] For example, assuming that the door of the refrigerator provided in this embodiment moves to the right to open the storage space, the gear is arranged at the right edge of the top of the box body 10. In this way, when the door is driven to open or close, the length of the movement trajectory of the door can be matched with the length of the movement trajectory of the rack 303. When the purpose is achieved, the use length of the rack 303 is reduced, thereby reducing the production cost.

[0069] In some embodiments, the driving motor 301 is located above or below the gear 302, and the transmission shaft of the driving motor 301 is inserted into the gear 302, so that when the driving motor 301 is turned on, the gear rotates driven by the transmission shaft.

[0070] In some embodiments, the drive motor 301 is connected to the gear through an intermediate gear transmission. Exemplarily, the free end of the transmission shaft of the drive motor 301 is provided with gear teeth, which are meshed with the gear to achieve meshing transmission. Exemplarily, the free end of the transmission shaft of the drive motor 301 is sleeved with an intermediate gear, which is meshed with the gear to achieve the transmission purpose of the drive motor 301 and the gear.

[0071] Optionally, the connecting rod assembly 40 includes: a first connecting rod 401, a first end of which is connected to the rotating motor 304 and rotates under the drive of the rotating motor 304; a second connecting rod 402, a first end of which is rotationally connected to the second end of the first connecting rod 401; a third connecting rod 403, a first end of which is rotationally connected to the second end of the second connecting rod 402, and the second end is rotationally connected to the door body; a fourth connecting rod 404, a first end of which is rotationally connected to the second connecting rod 402, and the second end is rotationally connected to the door body; wherein the second connecting rod 402, the third connecting rod 403, the fourth connecting rod 404 and the door body form a quadrilateral structure, and under the drive of the first connecting rod 401, the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 move to drive the door body to open or close the storage space by translational movement.

[0072] The connecting rod assembly 40 realizes linear reciprocating movement under the drive of the linear motion device. Under the action of the rotary motor 304, the relative positions and angles between the first connecting rod 401, the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 are changed, thereby driving the door body to move in translation.

[0073] For ease of description, the position where the door closes the storage space of the box body 10 is defined as the initial position. Similarly, the positions of the first connecting rod 401, the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 when the door closes the storage space of the box body 10 are their respective initial positions.

[0074] The rotating motor 304 rotates forward, and the door body opens; the rotating motor 304 rotates reversely, and the door body closes.

[0075] The rotating motor 304 is arranged on the rack 303 and connected to the first connecting rod 401. The first connecting rod 401 rotates around the rotating motor 304 under the action of the forward rotation of the rotating motor 304. During the rotation process, the first connecting rod 401 drives the second connecting rod 402 to move. The third connecting rod 403 and the fourth connecting rod 404 are both hinged on the second connecting rod 402. During the movement of the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 are driven to move. Among them, the second connecting rod 402, the third connecting rod 403, the fourth connecting rod 404 and the door body form a quadrilateral structure. When the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 move, the door body is also driven to change in displacement, and the door body moves parallel to the box body 10, thereby realizing the door body translational movement to open the storage space of the box body 10.

[0076] When the rotating motor 304 is reversed, the first connecting rod 401 rotates in the reverse direction around the rotating motor 304. During the reverse rotation process, the first connecting rod 401 drives the second connecting rod 402 to reset to the corresponding initial position. During the reset process of the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 are driven to reset to their respective initial positions. When the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 reset, the door body is also driven to change its displacement, and the door body moves parallel to the box body 10 to its initial position, thereby realizing the door body translation movement to close the storage space of the box body 10.

[0077] Optionally, the inner side wall of the door body is constructed with a first groove and a second groove, and the first groove is located above the second groove, the second end of the third connecting rod 403 extends into the second groove, and is rotatably connected to the door body through the first connecting shaft; the second end of the fourth connecting rod 404 extends into the first groove, and is rotatably connected to the door body through the second connecting shaft.

[0078] In this way, interference between the third connecting rod 403 and the fourth connecting rod 404 can be avoided, thereby ensuring smoothness of the door body during movement.

[0079] Optionally, a first end of the third connecting rod 403 is hinged to an end of the second connecting rod 402 .

[0080] Optionally, the first end of the fourth link 404 is connected to the middle of the second link 402 , and the distance from the first end of the fourth link 404 to the first end of the third link 403 matches the distance from the second end of the fourth link 404 to the second end of the third link 403 .

[0081] By connecting the first end of the fourth link 404 to the middle of the second link 402, and designing the distance from the first end of the fourth link 404 to the first end of the third link 403 to match the distance from the second end of the fourth link 404 to the second end of the third link 403, the stability of the formed quadrilateral structure during the opening or closing process of the door body is ensured, avoiding interference between the third link 403 and the fourth link 404 during movement, thereby causing the door body to get stuck during the opening or closing process.

[0082] Optionally, the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 are stacked up and down in pairs to avoid interference.

[0083] The second link 402, the third link 403 and the fourth link 404 are stacked up and down in pairs. For example, the third link 403 and the fourth link 404 are both hinged on the second link 402, the fourth link 404 is located above the second link 402, and the third link 403 is located below the second link 402. By arranging the second link 402, the third link 403 and the fourth link 404 up and down, it is possible to avoid interference between the second link 402, the third link 403 and the fourth link 404 during the deformation of the quadrilateral structure, thereby causing the door body to get stuck during the opening or closing process.

[0084] Optionally, the third connecting rod 403 is in a broken line shape, and when the door is opened, the third connecting rod 403 is located on one side of the fourth connecting rod 404 and does not overlap.

[0085] The third connecting rod 403 is in a broken line shape, wherein the third connecting rod 403 has at least one bend. The broken line-shaped third connecting rod 403 can not only be located at one side of the fourth connecting rod 404 and not overlap the fourth connecting rod 404 when the door is opened, but also can avoid the third connecting rod 403 from occupying too much space of the connecting rod assembly 40 when the door is closed and the connecting rod assembly 40 is stored.

[0086] Optionally, the length of the second connecting rod 402 is greater than the length of the first connecting rod 401, and the length of the first connecting rod 401 is less than the distance from the rotating motor 304 to the side edge of the opening of the storage space of the box body 10.

[0087] By designing the length of the second connecting rod 402 to be greater than the length of the first connecting rod 401, and the length of the first connecting rod 401 to be less than the distance from the rotating motor 304 to the edge of the opening side of the box body 10 in the storage space, it is not only possible to prevent the second end of the second connecting rod 402 from extending out of the box body 10 and interfering with the door body during the rotation of the second connecting rod 402, but also help to reduce the space occupied by the connecting rod assembly 40 when the door body is closed.

[0088] Optionally, there are two groups of connecting rod assemblies 40, and the two groups of connecting rod assemblies 40 are respectively connected to two symmetrical sides of the door body.

[0089] The two groups of connecting rod assemblies 40 are respectively connected to two symmetrical side parts of the door body, which can not only improve the supporting effect on the door body, but also improve the stability of the movement of the door body during opening or closing.

[0090] Optionally, the refrigerator further includes: a control device, which is electrically connected to the driving motor 301 and the rotating motor 304 of the sliding assembly 30, respectively, and the control device controls the rotation of the driving motor 301 and the rotating motor 304, thereby controlling the translation distance of the door body and the opening area of ​​the storage space.

[0091] The control device controls the driving motor 301 to rotate, thereby driving the linear motion device to move to one side along a straight line, and the control device controls the rotating motor 304 to rotate, thereby driving the connecting rod assembly 40 and the quadrilateral structure formed by the door body to deform, thereby realizing the control of the door body to move horizontally to open or close the storage space. In the process of controlling the door body to move horizontally, the control of the door body's translation distance is realized by driving the moving distance of the linear motion device and the deformation degree of the connecting rod assembly 40, thereby realizing the purpose of controlling the open area of ​​the storage space.
