Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] A refrigerator is a common household appliance that can keep food or other items at a constant low temperature. The refrigerator includes a box body and a door body. The box body is formed with a receiving cavity for receiving food or other items. The door body can be movably arranged on the box body so as to close or open the receiving cavity through the door body. However, when the door body is closed to close the receiving cavity, a gap is likely to appear between the door body and the box body, and the sealing performance of the receiving cavity is poor. Utility Model Content

[0003] The embodiment of the present application provides a refrigerator, which can solve the technical problem that when the door body is closed to seal the accommodating cavity, a gap is easily formed between the door body and the box body, and the sealing of the accommodating cavity is poor.

[0004] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0005] Box;

[0006] A door body, the door body being rotatably disposed on the box body;

[0007] The gravity self-closing structure comprises a fixed part and a movable part which cooperate with each other, wherein the fixed part is arranged on the box body, and the movable part is fixedly arranged on the door body;

[0008] The movable part is provided with a track groove; the fixed part is provided with a hinge shaft, and the hinge shaft can move in the track groove;

[0009] The surface of the fixed part facing the movable part is further provided with a first inclined portion and a second inclined portion, wherein the first end of the first inclined portion is connected to the fixed part, and the second end of the first inclined portion is inclined upward; the first end of the second inclined portion is connected to the second end of the first inclined portion, and the second end of the second inclined portion is inclined downward;

[0010] The movable member is provided with an abutment portion, and the abutment portion is used to abut the first inclined portion and the second inclined portion;

[0011] During the process of the door body rotating and closing, the abutting portion abuts against the first inclined portion and the second inclined portion in sequence; and the hinge shaft moves from the second end of the track groove toward the first end of the track groove.

[0012] The refrigerator of the embodiment of the present application adopts the above technical solution. When the door body rotates to close, the hinge shaft can move from the second end of the track groove to the first end of the track groove, and the abutment part abuts the first inclined part and the second inclined part in sequence. Since the door body has a certain gravity, when the door body rotates to open, it is necessary to overcome the gravity of the door body so that the door body can drive the abutment part to move from the second end of the second inclined part to the first end of the second inclined part, so that the second inclined part plays a certain role in limiting the abutment part, reducing the possibility of movement of the abutment part.

[0013] Furthermore, when the door body rotates and closes, when the abutting portion abuts against the second inclined portion, the abutting portion can move toward the second end of the second inclined portion under the weight of the door body, thereby making the process of the door body moving from the inclined portion to the second contact portion more convenient. When the abutting portion faces the second inclined portion, when the door body is closed to seal the accommodating cavity, the possibility of a gap between the door body and the box body can be reduced, thereby improving the sealing of the accommodating cavity.

[0039] In the related art, a refrigerator includes a box body and a door body, wherein the box body is formed with a receiving cavity for receiving food or other items, and the door body is movably arranged on the box body so as to close or open the receiving cavity through the door body. For example, the door body can be rotatably arranged on the box body, and when the door body is attached to the box body, the door body closes the receiving cavity, and when an angle is formed between the door body and the box body, the door body opens the receiving cavity so as to take out or put in food or other items through the receiving cavity.

[0040] However, when the door body is rotated to close the accommodating cavity through the door body, the door body moves toward the accommodating cavity. When the door body is attached to the surface of the box body, due to the influence of the air pressure change in the accommodating cavity, the door body is easily bounced off the surface of the box body, so that a gap is formed between the door body and the surface of the box body, thereby affecting the sealing of the accommodating cavity.

[0041] In view of this, the refrigerator of the embodiment of the present application

[0042] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] Reference Figure 1-Figure 4 An embodiment of the present application provides a refrigerator, which includes a cabinet 100 having a receiving cavity, a door 200 connected to the cabinet 100 to open and close the receiving cavity, and a refrigeration device for supplying cold air to the receiving cavity.

[0050] The cabinet 100 includes an inner container defining a receiving cavity, an outer shell connected to the outer side of the inner container to form the appearance of the refrigerator, and an insulating layer provided between the inner container and the outer shell to insulate the receiving cavity.

[0051] The box body 100 may define a plurality of accommodating chambers. In this embodiment, the plurality of accommodating chambers may include a refrigerating chamber and a freezing chamber located below the refrigerating chamber. It should be noted that the types and arrangements of the plurality of accommodating chambers of the refrigerator are not limited thereto.

[0052] The front end of the accommodating cavity is formed with a take-in and put-out opening, through which a user can place food into the accommodating cavity or take food out of the accommodating cavity. A rotatable door 200 is provided on the box body 100 to open or close the take-in and put-out opening of the accommodating cavity.

[0053] For example, the door body 200 may be rotatably connected to the housing 100 by a hinge assembly located at an upper portion of the door body 200 and a hinge assembly located at a lower portion of the door body 200 .

[0054] The door body 200 may have a door rear wall close to the box body 100 when the door body 200 is closed, a door front wall away from the box body 100 when the door body 200 is closed, and a door side wall connected to the door rear wall. The door front wall and the door rear wall are arranged opposite to each other, the door front wall and the door side wall are connected to form a door front edge, and the door rear wall and the door side wall are connected to form a door rear edge. The door rear edge and the door front edge are arranged parallel to each other.

[0055] In some possible implementations, the hinge assembly may be close to the door side wall, so that the door body 200 can rotate relative to the box body 100 through the hinge assembly, so as to close or open the accommodating cavity through the door body 200 .

[0056] For example, when the hinge assembly is located on the right side of the box 100, the right side wall of the door body 200 can be set as the door side wall. When the hinge assembly is located on the left side of the box 100, the left side wall of the door body 200 can be set as the door side wall.

[0057] A door seal may be provided on the rear wall of the door body 200. When the door body 200 is closed, the door seal surrounds the access opening and fits against the front end surface of the box body 100 to effectively seal the connection between the door body 200 and the box body 100, thereby ensuring that the door body 200 seals the access opening to prevent cold air from escaping. For example, the door seal may be ring-shaped.

[0058] For example, the upper and lower ends of the door body 200 may be provided with hinge assemblies. For the hinge assembly located at the upper end of the door body 200, the hinge assembly may include a hinge plate 350 connected to the upper end of the box body 100, at least one hinge shaft, and a limited shaft connected to the hinge plate 350 to form a guide for the movement of the door body 200. The hinge plate 350 and the hinge shaft may be formed integrally, or may be provided separately and assembled with each other.

[0059] The number of hinge axes may be set to one. Alternatively, the number of hinge axes may be set to at least two. For example, the number of hinge axes may be set to two, and the two hinge axes are respectively set to the first hinge axis 310 and the second hinge axis 320.

[0060] For the hinge assembly located at the upper end of the door body 200, the hinge assembly may include a guide member connected to the upper end of the door body 200. The guide member may be provided with a track groove 420. The track groove 420 may accommodate the hinge shaft, so that the door body 200 can be opened or closed by the sliding process of the hinge shaft in the track groove 420.

[0061] In some embodiments, the refrigerator may further include a gravity self-closing structure. The gravity self-closing structure may be disposed at the lower end of the door body 200, and the gravity self-closing structure may include a fixed part 300 and a movable part 400 that cooperate with each other.

[0062] The fixing member 300 can be fixedly arranged on the box body 100, and the movable member 400 can be fixedly arranged on the door body 200. The movable member 400 and the fixing member 300 can be arranged in a vertical direction. The hinge assembly at the lower end of the door body 200 can be reused to form at least one of the fixing member 300 and the movable member 400, so as to facilitate the formation process of the gravity self-closing structure.

[0063] Alternatively, the fixing member 300 may be fixedly disposed on the door body 200 , and the movable member 400 may be fixedly disposed on the box body 100 .

[0064] When the door body 200 rotates and closes to a closed state, the door body 200 can move toward the box body 100 through the gravity self-closing structure. The door body 200 can move in a vertical direction relative to the fixed part 300 driven by the movable part 400, so that the door body 200 can abut against the box body 100.

[0065] When the door body 200 needs to be rotated to open, the gravity of the door body 200 needs to be overcome to separate the door body 200 from the box body 100, so as to reduce the gap between the door body 200 and the box body 100 when the door body 200 is in a closed state, thereby improving the sealing of the accommodating cavity.

[0066] For example, the refrigerator can be configured as a side-by-side refrigerator, and the number of door bodies 200 of the side-by-side refrigerator is set to two, so as to seal multiple accommodating cavities through the two door bodies 200; compared with other types of refrigerators such as cross-door refrigerators, the height of the door body 200 of the side-by-side refrigerator is higher, and the weight of the door body 200 of the side-by-side refrigerator is larger, so that the door body 200 of the side-by-side refrigerator has a better gravity self-closing effect through the gravity self-closing structure, thereby increasing the gravity that needs to be overcome when rotating the door body 200 to open.

[0067] It should be noted that the gap between the door body 200 and the box body 100 can also be reduced by providing a suction aid or other structures between the door body 200 and the box body 100. However, compared with other types of refrigerators such as cross-door refrigerators, the door body 200 of the side-by-side refrigerator is heavier, and the side-by-side refrigerator is usually unable to achieve a tight seal between the door body 200 and the box body 100 only by the suction aid, which also makes the gravity self-closing structure more suitable for refrigerators such as side-by-side refrigerators with heavy door bodies 200 or other types of refrigerators where the door body 200 can bear a large weight, so as to further improve the sealing effect of the door body 200 on the accommodating cavity.

[0068] In some embodiments, the refrigerator can be arranged in a cabinet. When the door body 200 is in a closed state, in a built-in refrigerator whose front wall of the door body 200 is flush with the front end of the cabinet wall, after the door body 200 is opened until the front wall of the door and the cabinet wall are in the same plane (the door body 200 is opened approximately 90°), interference occurs between the front wall of the door and the cabinet wall, and the door body 200 cannot be opened further, that is, the maximum opening angle of the door body 200 is 90°, which affects the user's access to items in the refrigeration device.

[0069] Exemplarily, during the process of rotating and opening the door body 200, the movement trajectory of the door body 200 can be controlled to include the following stages: while the door body 200 continues to open from a preset opening angle to a maximum opening angle, the door body 200 is driven to move from the pivot side to the opening side, thereby avoiding interference between the door body 200 and the cabinet wall when the door body 200 is further opened, thereby increasing the opening angle of the door body 200 (greater than 120°) to facilitate users to store and retrieve items.

[0070] In some embodiments, the hinge assembly can be configured such that before the door body 200 rotates and opens to a preset opening angle, the door body 200 first moves toward the opening side and then moves toward the pivoting side while rotating and opening.

[0071] During the process of rotating and opening the door body 200, the door body 200 first moves toward the opening side, that is, gradually moves away from the cabinet wall on the pivot side, which can increase the distance between the end of the door body 200 on the pivot side and the cabinet wall on the pivot side, and avoid the cabinet wall. On the one hand, even if there is no gap between the built-in refrigerator and the cabinet, interference between the door body 200 and the cabinet wall can be avoided during the door opening process. On the other hand, it can provide more space for the door body 200 to move toward the pivot side in the subsequent further opening process, avoiding interference between the door body 200 and the cabinet wall during the opening process.

[0072] It is easy to understand that after the door body 200 moves to the opening side, it moves to the pivoting side to further open the door body 200, and can expose a larger area of ​​the storage space in the box body 100 to the user, making it easier for the user to take items.

[0073] It should be noted that the pivot side mentioned above refers to the side of the built-in refrigerator corresponding to the rotation end of the door body 200. The opening side mentioned above refers to the side of the built-in refrigerator corresponding to the free end of the door body 200.

[0074] In some embodiments, the number of hinge shafts is set to one. When the door body 200 is in a closed state, the hinge shaft can be located at the first end of the track groove 420. When the door body 200 is in an open state, the hinge shaft can be located at the second end of the track groove 420. During the process of the door body 200 rotating and opening, the hinge shaft can move from the first end of the track groove 420 toward the second end of the track groove 420, thereby realizing the rotation of the door body 200.

[0075] Exemplarily, the track groove 420 may include a groove wall and an arc-shaped groove bottom connected to the groove wall in a smooth transition.

[0076] The end of the hinge shaft that matches the bottom of the arc groove may have an arc end face, and the shape of the arc end face matches the shape of the bottom of the arc groove. This can enhance the smoothness during the opening and closing of the door body 200, and make the hinge shaft and the track groove 420 match more tightly and smoothly. Of course, this is not limited to the above, and the hinge shaft can also be directly set to a columnar shape. In this case, the groove wall and the groove bottom of the track groove 420 are set to a plate shape that matches the hinge shaft.

[0077] In some embodiments, the shaft portion of the hinge shaft that matches the track groove 420 is columnar. The shaft diameter of the shaft portion is the same as the groove width of the track groove 420 to enhance the stability of the hinge mechanism. Of course, this is not limited to this. The shaft portion can also be set to a stepped type, as long as the cooperation between the shaft portion and the track groove 420 can enable the door body 200 to move according to the preset motion trajectory.

[0078] Specifically, the track groove 420 may extend along the arrangement direction of the pivot side and the opening side. During the process of the door body 200 rotating to open, the hinge shaft may first move along the track groove 420 toward the end of the track groove 420 close to the opening side, then move along the track groove 420 toward the end of the track groove 420 close to the pivot side, and then move along the track groove 420 toward the end of the track groove 420 close to the opening side. The door body 200 is driven to move toward the opening side first, then toward the pivot side, and then toward the opening side during the process of rotating to open.

[0079] Along the direction from the opening side to the pivoting side, the track groove 420 may include a first groove section, a second groove section and a third groove section connected in sequence, wherein an end of the first groove section away from the second groove section is set as the first end of the track groove 420, and an end of the third groove section away from the second groove section is set as the second end of the track groove 420.

[0080] When the door body 200 rotates to open, when the hinge shaft is in the first slot section and moves toward the second slot section, the hinge shaft is guided to move along the track slot 420 close to the opening side to drive the door body 200 to move toward the opening side first.

[0081] When the door body 200 rotates open until the hinge axis is located at the junction of the first slot section and the second slot section and continues to rotate open, the hinge axis is in the second slot section and moves toward the third slot section, guiding the hinge axis to move along the track slot 420 toward the end of the track slot 420 close to the pivot side, thereby driving the door body 200 to move toward the pivot side.

[0082] When the door body 200 rotates open until the hinge axis is located at the junction of the second groove section and the third groove section, and continues to rotate open, the hinge axis moves in the third groove section and away from the second groove section, guiding the hinge axis to move along the track groove 420 toward the end of the track groove 420 close to the opening side, thereby driving the door body 200 to move toward the opening side.

[0083] Of course, this is not limiting, and it is understandable that in other embodiments, the specific structure of the track groove 420 and the setting of the extension direction only need to be able to guide the hinge axis to move along a preset motion track.

[0084] In some embodiments, the number of hinge axes is set to two. The two hinge axes are respectively set to be a first hinge axis 310 and a second hinge axis 320. The first hinge axis 310 is closer to the second end of the track groove 420 relative to the second hinge axis 320, and the second hinge axis 320 is closer to the first end of the track groove 420 relative to the first hinge axis 310.

[0085] When the door 200 is in a closed state, the second hinge shaft 320 may be located at the first end of the track groove 420, and the first hinge shaft 310 and the second hinge shaft 320 are arranged at intervals. When the door 200 is in an open state, the first hinge shaft 310 may be located at the second end of the track groove 420.

[0086] During the process of rotating and opening the door body 200, when the first hinge shaft 310 and the second hinge shaft 320 are in the first slot section and move toward the second slot section, the hinge shaft is guided to move along the track slot 420 close to the opening side to drive the door body 200 to move toward the opening side first.

[0087] When the door body 200 rotates open until the second hinge shaft 320 is located in the first slot section and the first hinge shaft 310 is located in the second slot section, and continues to rotate open, the first hinge shaft 310 is in the second slot section and moves toward the third slot section, guiding the hinge shaft to move along the track groove 420 toward the end of the track groove 420 close to the pivot side, so as to drive the door body 200 to move toward the pivot side.

[0088] When the door body 200 rotates open until the second hinge shaft 320 is located in the second slot section and the first hinge shaft 310 is located in the third slot section, and continues to rotate open, the first hinge shaft 310 moves in the third slot section and away from the second slot section, guiding the hinge shaft to move along the track groove 420 toward the end of the track groove 420 close to the opening side, thereby driving the door body 200 to move toward the opening side.

[0089] It should be noted that the track groove 420 may be provided with a first inflection point P and a second inflection point Q which are arranged at intervals. The first inflection point P may be provided between the first groove section and the second groove section, and the second inflection point Q may be provided between the second groove section and the third groove section.

[0090] In a plane perpendicular to the door rear wall and the door side walls, for example, in the upper top surface or lower bottom surface of the door body 200, a straight line parallel to the door rear wall can be used as the first reference line, and the first reference line can be gradually moved from the door rear wall toward the door front wall. The position where the first reference line is tangent to the trajectory groove 420 can be set as the first inflection point P of the trajectory groove 420.

[0091] In a plane perpendicular to the door rear wall and the door side walls, for example, in the upper top surface or lower bottom surface of the door body 200, a straight line parallel to the door side wall can be used as a second reference line, and the second reference line is gradually moved from the door side wall toward the middle of the door body 200. The position where the second reference line is tangent to the trajectory groove 420 can be set as the second inflection point Q of the trajectory groove 420.

[0092] The curvature of the first groove section may be smaller than that of the second groove section, and the curvature of the second groove section may be larger than that of the third groove section. The first end of the track groove 420 is close to the door front wall relative to the first inflection point P, and the first end of the first groove section is far away from the door side wall relative to the first inflection point P. The first inflection point P is close to the door rear wall relative to the second inflection point Q, and the first inflection point P is far away from the door side wall relative to the second inflection point Q. The second inflection point Q is far away from the door front wall relative to the second end of the track groove 420, and the second inflection point Q is close to the door side wall relative to the second end of the track groove 420.

[0093] In some embodiments, during the process of the door body 200 rotating to open or rotating to close, the moving directions of the first hinge shaft 310 and the second hinge shaft 320 can be determined according to the track grooves 420 at corresponding positions.

[0094] For example, when the first hinge axis 310 and the second hinge axis 320 move in the track groove 420, the first hinge axis 310 and the second hinge axis 320 will contact the inner wall of the track groove 420, and the tangent direction of the track groove 420 contacting the first hinge axis 310 can be set as the moving direction of the first hinge axis 310, and the tangent direction of the track groove 420 contacting the second hinge axis 320 can be set as the moving direction of the second hinge axis 320.

[0095] It is easy to understand that when the hinge axis moves in the first slot segment and the second slot segment, the curvature of the first slot segment is smaller than the curvature of the second slot segment, the moving direction of the hinge axis in the first slot segment changes less, and the moving direction of the hinge axis in the second slot segment changes more.

[0096] When the hinge shaft moves in the second slot section and the third slot section, the curvature of the third slot section is smaller than that of the second slot section, the moving direction of the hinge shaft in the third slot section changes less, and the moving direction of the hinge shaft in the second slot section changes more.

[0097] For example, when the first hinge axis 310 and the second hinge axis 320 move in the first slot section of the track slot 420, the moving direction of the first hinge axis 310 is relatively close to the moving direction of the second hinge axis 320. When the first hinge axis 310 moves in the first slot section of the track slot 420 and the second hinge axis 320 moves in the second slot section of the track slot 420, the angle formed by the moving direction of the first hinge axis 310 and the moving direction of the second hinge axis 320 is relatively large.

[0098] When the door body 200 rotates to close, the first hinge shaft 310 and the second hinge shaft 320 can move in the track groove 420 from the second end of the track groove 420 toward the first end of the track groove 420 .

[0099] In some embodiments, the opening angle φ of the door body 200 may have a first setting angle, a second setting angle, and a third setting angle that decrease in sequence. When the opening angle of the door body 200 is set to the first setting angle, the abutting portion 410 abuts against the first end of the first inclined portion 330. When the opening angle of the door body 200 is set to the second setting angle, the abutting portion 410 abuts against the second end of the first inclined portion 330. When the opening angle of the door body 200 is set to the third setting angle, the abutting portion 410 abuts against the second end of the second inclined portion 340.

[0100] During the process of rotating the door body 200 to open or close, the user pulls or pushes the door body 200 to rotate around the first hinge axis 310 and the second hinge axis 320. When the door body 200 rotates to between the second set angle and the third set angle, the door body 200 moves in the vertical direction relative to the fixed part 300 driven by the movable part 400.

[0101] During the process of rotating and opening the door body 200 , the door body 200 can rotate from the third setting angle toward the second setting angle, the opening angle of the door body 200 gradually increases, and the door body 200 moves upward in the vertical direction driven by the abutment portion 410 .

[0102] When the third setting angle is smaller, the user can feel the rising process of the door body 200 earlier during the door opening process; when the second setting angle is smaller, the user can feel the end of the rising process of the door body 200 earlier during the door opening process; and when the difference between the second setting angle and the third setting angle is smaller, the user can feel the shorter the rising process of the door body 200 is during the door opening process.

[0103] During the process of the door body 200 rotating and closing, the door body 200 can rotate from the second setting angle toward the third setting angle, the opening angle of the door body 200 gradually decreases, and the door body 200 drives the abutment portion 410 to move downward in the vertical direction.

[0104] When the second setting angle is smaller, the user can feel the descending process of the door body 200 earlier during the process of closing the door; when the third setting angle is smaller, the user can feel the end of the descending process of the door body 200 earlier during the process of opening the door; and the smaller the difference between the second setting angle and the third setting angle, the shorter the descending process of the door body 200 felt by the user during the process of opening the door.

[0105] During the process of rotating and closing the door body 200, the first hinge shaft 310 and the second hinge shaft 320 can move in the track groove 420 from the second end of the track groove 420 toward the first end of the track groove 420, and the first hinge shaft 310 and the second hinge shaft 320 can move from the third groove section toward the second groove section and the first groove section.

[0106] When the opening angle φ of the door body 200 is greater than the first set angle, the abutment portion 410 may be located at a side of the first end of the first inclined portion 330 away from the second end of the first inclined portion 330. The first hinge axis 310 may be located at the second end of the track groove 420, and the second hinge axis 320 may be located in the third groove section. Alternatively, the second hinge axis 320 may be located in the second groove section.

[0107] When the opening angle φ of the door body 200 is equal to the first set angle, the abutment portion 410 may be located at the first end of the first inclined portion 330. The first hinge shaft 310 may be located in the first slot section, and the second hinge shaft 320 may be located in the first slot section.

[0108] It is easy to understand that during the process of rotating and closing the door body 200, when the opening angle φ of the door body 200 is less than the first set angle, the abutment portion 410 moves obliquely upward from the first end of the first inclined portion 330 to the second end of the first inclined portion 330, and the abutment portion 410 moves from the first end of the second inclined portion 340 to the second end of the second inclined portion 340, and the door body 200 moves first upward and then downward driven by the abutment portion 410 and the inclined portion.

[0109] The first hinge shaft 310 and the second hinge shaft 320 move in the first groove section of the track groove 420, and the moving direction of the first hinge shaft 310 is relatively close to the moving direction of the second hinge shaft 320, so that the horizontal movement of the door body 200 driven by the first hinge shaft 310 and the second hinge shaft 320 is more stable, thereby reducing the sense of frustration of the door body 200 during the rotation and closing process.

[0110] In some embodiments, the first slot section may be a straight slot section. When the first hinge shaft 310 and the second hinge shaft 320 move in the first slot section of the track slot 420 , the moving direction of the first hinge shaft 310 is the same as the moving direction of the second hinge shaft 320 .

[0111] For example, when the opening angle φ of the door body 200 is greater than 30 degrees, the opening angle φ of the door body 200 is greater than the first set angle, the abutment portion 410 is located on the side of the first end of the first inclined portion 330 away from the second end of the first inclined portion 330, and the abutment portion 410 is not in contact with the first inclined portion 330 and the second inclined portion 340.

[0112] When the opening angle φ of the door body 200 is set to 30 degrees, the opening angle φ of the door body 200 is set to the first setting angle, the abutting portion 410 is located at the first end of the first inclined portion 330, and the first hinge shaft 310 moves to the first inflection point P of the track groove 420. When the opening angle φ of the door body 200 is set to: 20 degrees ≤ φ ≤ 30 degrees, the abutting portion 410 abuts against the first inclined portion 330.

[0113] When the opening angle φ of the door body 200 is 20 degrees, the opening angle φ of the door body 200 is set to a second set angle, the abutment portion 410 abuts against the second end of the first inclined portion 330, the first hinge axis 310 can be located in the first groove section, and the second hinge axis 320 can be located in the first groove section.

[0114] When the opening angle φ of the door body 200 is 10 degrees, the opening angle φ of the door body 200 is set to the third setting angle, and the abutting portion 410 abuts against the second end of the second inclined portion 340. When the opening angle φ of the door body 200 is set to: 0 degrees ≤ φ < 15 degrees, the abutting portion 410 abuts against the surface of the fixed member 300 facing the movable member 400.

[0115] When the opening angle φ of the door body 200 is greater than the third set angle and less than the second set angle, the first hinge shaft 310 and the second hinge shaft 320 move in the first groove section of the track groove 420, so that the door body 200 can move more stably in the horizontal direction driven by the first hinge shaft 310 and the second hinge shaft 320.

[0116] Phase 1

[0117] During the process of the door body 200 rotating and closing, when the opening angle φ of the door body 200 is greater than 30 degrees, the opening angle φ of the door body 200 is greater than the first set angle, the abutting portion 410 is located at a side of the first end of the first inclined portion 330 away from the second end of the first inclined portion 330, and the abutting portion 410 does not contact the first inclined portion 330 and the second inclined portion 340. The abutting portion 410 moves toward the first inclined portion 330, and when the opening angle φ of the door body 200 is 30 degrees, the door body 200 is at the first set angle, and the abutting portion 410 can move to the first end of the first inclined portion 330.

[0118] The first hinge axis 310 and the second hinge axis 320 can move in the trajectory groove 420 from the second end of the trajectory groove 420 toward the first end of the trajectory groove 420, the second hinge axis 320 can move through the second groove section to the first groove section, and the first hinge axis 310 can move from the third groove section through the second groove section to the first inflection point P.

[0119] It is easy to understand that when the opening angle of the door body 200 is greater than 30 degrees, the moving direction of the first hinge axis 310 and the moving direction of the second hinge axis 320 form a larger angle, and the first hinge axis 310 and the second hinge axis 320 are subjected to greater force. The abutting portion 410 abuts against the fixing member 300, so that the door body 200 only needs to move in the horizontal direction, and does not need to move in the vertical direction, so that the rotation process of the door body 200 is more stable.

[0120] Phase II

[0121] When the opening angle φ of the door body 200 is set to: 20 degrees ≤ φ ≤ 30 degrees, the abutting portion 410 abuts against the first inclined portion 330, and the door body 200 can drive the abutting portion 410 to move upward under the action of gravity, so that the abutting portion 410 moves from the first end of the first inclined portion 330 to the second end of the first inclined portion 330, and the movable member 400 drives the door body 200 to move upward through the abutting portion 410. When the opening angle φ of the door body 200 = 20 degrees, the door body 200 is at the second set angle, and the abutting portion 410 moves to the second end of the first inclined portion.

[0122] The first hinge shaft 310 and the second hinge shaft 320 move in the first groove section of the track groove 420, and the moving direction of the first hinge shaft 310 is relatively close to the moving direction of the second hinge shaft 320, so that the door body 200 can move more stably in the horizontal direction driven by the first hinge shaft 310 and the second hinge shaft 320.

[0123] Phase 3

[0124] When the opening angle φ of the door body 200 is set to: 10 degrees ≤ φ < 20 degrees, the abutting portion 410 abuts against the second inclined portion 340 to drive the abutting portion 410 to move obliquely downward on the second inclined portion 340. When the opening angle φ of the door body 200 is ≤ 10 degrees, the abutting portion 410 can abut against the fixing member 300, and the door seal located on the rear wall of the door body 200 fits with the front end surface of the box body 100 to effectively seal the connection between the door body 200 and the box body 100.

[0125] For example, when the opening angle φ of the door body 200 is greater than 30 degrees, the opening angle φ of the door body 200 is greater than the first set angle, the abutment portion 410 is located on the side of the first end of the first inclined portion 330 away from the second end of the first inclined portion 330, and the abutment portion 410 is not in contact with the first inclined portion 330 and the second inclined portion 340.

[0126] When the opening angle φ of the door body 200 is set to 30 degrees, the opening angle φ of the door body 200 is set to the first setting angle, the abutting portion 410 is located at the first end of the first inclined portion 330, and the first hinge shaft 310 moves into the first groove section. When the opening angle φ of the door body 200 is set to: 20 degrees ≤ φ ≤ 30 degrees, the abutting portion 410 abuts against the first inclined portion 330.

[0127] When the opening angle φ of the door body 200 is 20 degrees, the opening angle φ of the door body 200 is set to a second set angle, the abutment portion 410 abuts against the second end of the first inclined portion 330, the first hinge axis 310 can be located in the first groove section, and the second hinge axis 320 can be located in the first groove section.

[0128] When the opening angle φ of the door body 200 is 10 degrees, the opening angle φ of the door body 200 is set to the third setting angle, and the abutting portion 410 abuts against the second end of the second inclined portion 340. When the opening angle φ of the door body 200 is set to: 0 degrees ≤ φ < 15 degrees, the abutting portion 410 abuts against the surface of the fixed member 300 facing the movable member 400.

[0129] When the opening angle φ of the door body 200 is greater than the third set angle and less than the second set angle, the first hinge shaft 310 and the second hinge shaft 320 move in the first groove section of the track groove 420, so that the door body 200 can move more stably in the horizontal direction driven by the first hinge shaft 310 and the second hinge shaft 320.

[0130] Phase 1

[0131] During the process of the door body 200 rotating and closing, when the opening angle φ of the door body 200 is greater than 30 degrees, the opening angle φ of the door body 200 is greater than the first set angle, the abutting portion 410 is located at a side of the first end of the first inclined portion 330 away from the second end of the first inclined portion 330, and the abutting portion 410 does not contact the first inclined portion 330 and the second inclined portion 340. The abutting portion 410 moves toward the first inclined portion 330, and when the opening angle φ of the door body 200 is 30 degrees, the door body 200 is at the first set angle, and the abutting portion 410 can move to the first end of the first inclined portion 330.

[0132] The first hinge axis 310 and the second hinge axis 320 can move in the trajectory groove 420 from the second end of the trajectory groove 420 toward the first end of the trajectory groove 420, the second hinge axis 320 can move through the second groove section to the first groove section, and the first hinge axis 310 can move from the third groove section through the second groove section to the first groove section.

[0133] It is easy to understand that when the opening angle of the door body 200 is greater than 30 degrees, the moving direction of the first hinge axis 310 and the moving direction of the second hinge axis 320 form a larger angle, and the first hinge axis 310 and the second hinge axis 320 are subjected to greater force. The abutting portion 410 abuts against the fixing member 300, so that the door body 200 only needs to move in the horizontal direction, and does not need to move in the vertical direction, so that the rotation process of the door body 200 is more stable.

[0134] Phase II

[0135] When the opening angle φ of the door body 200 is set to: 20 degrees ≤ φ ≤ 30 degrees, the abutting portion 410 abuts against the first inclined portion 330, and the door body 200 can drive the abutting portion 410 to move upward under the action of gravity, so that the abutting portion 410 moves from the first end of the first inclined portion 330 to the second end of the first inclined portion 330, and the movable member 400 drives the door body 200 to move upward through the abutting portion 410. When the opening angle φ of the door body 200 = 20 degrees, the door body 200 is at the second set angle, and the abutting portion 410 moves to the second end of the first inclined portion.

[0136] The first hinge shaft 310 and the second hinge shaft 320 move in the first groove section of the track groove 420, and the moving direction of the first hinge shaft 310 is relatively close to the moving direction of the second hinge shaft 320, so that the door body 200 can move more stably in the horizontal direction driven by the first hinge shaft 310 and the second hinge shaft 320.

[0137] Phase 3

[0138] When the opening angle φ of the door body 200 is set to: 10 degrees ≤ φ < 20 degrees, the abutting portion 410 abuts against the second inclined portion 340 to drive the abutting portion 410 to move obliquely downward on the second inclined portion 340. When the opening angle φ of the door body 200 is ≤ 10 degrees, the abutting portion 410 can abut against the fixing member 300, and the door seal located on the rear wall of the door body 200 fits with the front end surface of the box body 100 to effectively seal the connection between the door body 200 and the box body 100.

[0139] For example, when the opening angle φ of the door body 200 is greater than 30 degrees, the opening angle φ of the door body 200 is greater than the first set angle, the abutment portion 410 is located on the side of the first end of the first inclined portion 330 away from the second end of the first inclined portion 330, and the abutment portion 410 is not in contact with the first inclined portion 330 and the second inclined portion 340.

[0140] When the opening angle φ of the door body 200 is set to 30 degrees, the opening angle φ of the door body 200 is set to the first setting angle, the abutting portion 410 is located at the first end of the first inclined portion 330, and the first hinge shaft 310 moves to the first inflection point P of the track groove 420. When the opening angle φ of the door body 200 is set to: 20 degrees ≤ φ ≤ 30 degrees, the abutting portion 410 abuts against the first inclined portion 330.

[0141] When the opening angle φ of the door body 200 is 15 degrees, the opening angle φ of the door body 200 is set to a second set angle, the abutment portion 410 abuts against the second end of the first inclined portion 330, the first hinge axis 310 can be located in the first groove section, and the second hinge axis 320 can be located in the first groove section.

[0142] When the opening angle φ of the door body 200 is 0 degrees, the opening angle φ of the door body 200 is set to a third set angle, and the abutting portion 410 abuts against the second end of the second inclined portion 340 .

[0143] When the opening angle φ of the door body 200 is greater than the third set angle and less than the second set angle, the first hinge shaft 310 and the second hinge shaft 320 move in the first groove section of the track groove 420, so that the door body 200 can move more stably in the horizontal direction driven by the first hinge shaft 310 and the second hinge shaft 320.

[0144] Phase 1

[0145] During the process of the door body 200 rotating and closing, when the opening angle φ of the door body 200 is greater than 30 degrees, the opening angle φ of the door body 200 is greater than the first set angle, the abutting portion 410 is located at a side of the first end of the first inclined portion 330 away from the second end of the first inclined portion 330, and the abutting portion 410 does not contact the first inclined portion 330 and the second inclined portion 340. The abutting portion 410 moves toward the first inclined portion 330, and when the opening angle φ of the door body 200 is 30 degrees, the door body 200 is at the first set angle, and the abutting portion 410 can move to the first end of the first inclined portion 330.

[0146] The first hinge axis 310 and the second hinge axis 320 can move in the trajectory groove 420 from the second end of the trajectory groove 420 toward the first end of the trajectory groove 420, the second hinge axis 320 can move through the second groove section to the first groove section, and the first hinge axis 310 can move from the third groove section through the second groove section to the first inflection point P.

[0147] It is easy to understand that when the opening angle of the door body 200 is greater than 30 degrees, the moving direction of the first hinge axis 310 and the moving direction of the second hinge axis 320 form a larger angle, and the first hinge axis 310 and the second hinge axis 320 are subjected to greater force. The abutting portion 410 abuts against the fixing member 300, so that the door body 200 only needs to move in the horizontal direction, and does not need to move in the vertical direction, so that the rotation process of the door body 200 is more stable.

[0148] Phase II

[0149] When the opening angle φ of the door body 200 is set to: 15 degrees ≤ φ ≤ 30 degrees, the abutting portion 410 abuts against the first inclined portion 330, and the door body 200 can drive the abutting portion 410 to move upward under the action of gravity, so that the abutting portion 410 moves from the first end of the first inclined portion 330 to the second end of the first inclined portion 330, and the movable member 400 drives the door body 200 to move upward through the abutting portion 410. When the opening angle φ of the door body 200 = 15 degrees, the door body 200 is at the second set angle, and the abutting portion 410 moves to the second end of the first inclined portion.

[0150] The first hinge shaft 310 and the second hinge shaft 320 move in the first groove section of the track groove 420, and the moving direction of the first hinge shaft 310 is relatively close to the moving direction of the second hinge shaft 320, so that the door body 200 can move more stably in the horizontal direction driven by the first hinge shaft 310 and the second hinge shaft 320.

[0151] Phase 3

[0152] When the opening angle φ of the door body 200 is set to: 0 degrees ≤ φ < 15 degrees, the abutting portion 410 abuts against the second inclined portion 340 to drive the abutting portion 410 to move obliquely downward on the second inclined portion 340. When the opening angle φ of the door body 200 is 0 degrees, the abutting portion 410 can abut against the fixing member 300, and the door seal located on the rear wall of the door body 200 fits with the front end surface of the box body 100 to effectively seal the connection between the door body 200 and the box body 100.

[0153] For example, the number of hinge axes may be set to one.

[0154] When the abutment portion 410 is located at the first end of the second inclined portion 340, the door body 200 is at the highest point, and a first distance is set between the bottom of the abutment portion 410 and the upper surface of the fixing member 300. The first distance is set to be greater than or equal to 3 mm and less than or equal to 6 mm. For example, the first distance can be set to any distance range of 3 mm-3.5 mm, 3.5 mm-4 mm, 4 mm-4.5 mm, 4.5 mm-5 mm, 5 mm-5.5 mm, and 5.5 mm-6 mm.

[0155] When the abutment portion 410 is located at one end of the first inclined portion 330 away from the second inclined portion 340, a second distance is set between the bottom of the abutment portion 410 and the upper surface of the fixing member 300, and the second distance is set to be greater than or equal to 5 mm and less than or equal to 8 mm. For example, the second distance can be set to any distance range of 5 mm-5.5 mm, 5.5 mm-6 mm, 6 mm-6.5 mm, 6.5 mm-7 mm, 7 mm-7.5 mm, and 7.5 mm-8 mm, so as to reduce the possibility of the hinge shaft being damaged by excessive impact force of the door body 200 while ensuring the gravity self-closing effect.

[0156] The moving distance of the door body 200 in the vertical direction can be greater than or equal to 2 mm and less than or equal to 10 mm. For example, the moving distance of the door body 200 in the vertical direction can be set within any length range of 2 mm-3 mm, 3 mm-4 mm, 4 mm-5 mm, 5 mm-6 mm, 6 mm-7 mm, 7 mm-8 mm, 8 mm-9 mm, and 9 mm-10 mm to reduce the user's sense of frustration during the door closing process.

[0157] For example, one end of the first inclined portion 330 away from the second inclined portion 340 faces the front side of the box body 100, and the angle between the tangent direction of the first inclined portion 330 away from the second inclined portion 340 and the side surface of the box body 100 is less than or equal to 15 degrees. For example, the angle between the tangent direction of the first inclined portion 330 away from the second inclined portion 340 and the side surface of the box body 100 can be set within any angle range of 0-5 degrees, 5-10 degrees, and 10-15 degrees.

[0158] It is easy to understand that in the embodiment of the present application, when the abutment portion 410 moves to the side of the first inclined portion 330 away from the second inclined portion 340, the abutment portion 410 can be suspended, the abutment portion 410 can not contact any surface of the fixed member 300, and the bottom height of the abutment portion 410 can be lower than or equal to the height of the first inclined portion 330 away from the second inclined portion 340. For example, when the bottom of the abutment portion 410 is separated from the first inclined portion 330, the height of the abutment portion 410 can remain unchanged, or the height of the abutment portion 410 can continue to decrease, thereby further reducing the distance between the movable member 400 and the fixed member 300.

[0159] The fixing member 300 may have a hollow area. When the abutment portion 410 is located on the side of the first inclined portion 330 away from the second inclined portion 340, the abutment portion 410 is located in the hollow area, so that the abutment portion 410 may not contact any surface of the fixing member 300, thereby reducing the friction between the abutment portion 410 and the fixing member 300, and making the rotation process of the door body 200 smoother.

[0160] For example, when the abutment portion 410 moves to the side of the first inclined portion 330 away from the second inclined portion 340, the abutment portion 410 can abut against the surface of the fixing member 300 facing the movable member 400; however, relative to the implementation mode in which the abutment portion 410 abuts against the fixing member 300, the abutment portion 410 in the embodiment of the present application is suspended, so that there is no need to set a structure supporting the abutment portion 410 on the side of the first inclined portion 330 away from the second inclined portion 340, further reducing the assembly space required for the fixing member, making the setting of the gravity self-closing structure more compact; and, the abutment portion 410 is suspended, which can also reduce the friction between the abutment portion 410 and the fixing member 300, making the rotation process of the door body 200 smoother.

[0161] Furthermore, relative to the implementation mode in which the first inclined portion 330 and the second inclined portion 340 are located around the hinge axis, by arranging the connected first inclined portion 330 and the second inclined portion 340 at intervals on the hinge axis, the arrangement of the first inclined portion 330 and the second inclined portion 340 is made more flexible, and the bottom of the abutment portion 410 can be closer to the surface of the fixed part 300 facing the movable part 400 relative to the bottom of the track groove 420, so that the arrangement of the gravity self-closing structure is more compact, and the distance between the lower end of the door body 200 and the hinge plate 350 is reduced.

[0162] When the abutting portion 410 moves to the side of the first inclined portion 330 away from the second inclined portion 340, the abutting portion 410 is suspended, which can further reduce the distance between the lower end of the door body 200 and the hinge plate 350, reduce the assembly space required for the fixing part 300 and the movable part 400, and make the setting between the fixing part 300 and the movable part 400 more compact, thereby increasing the height of the door body 200 and increasing the volume of the door body 200; and, when the height of the door body 200 increases, the length of the box body 100 can be increased downward, thereby increasing the volume of the box body 100 when the height of the refrigerator remains unchanged.

[0163] When the door body 200 is at the third setting angle, the door body 200 may not be in the closed state. Alternatively, the door body 200 may not be in the closed state.

[0164] The third setting angle can be set to be greater than or equal to -5 degrees and less than or equal to 10 degrees, and the third setting angle is smaller than the second setting angle. For example, the third setting angle can be set within any angle range of -5 degrees to 0 degrees, 0 degrees to 5 degrees, 5 degrees to 8 degrees, 8 degrees to 10 degrees, 10 degrees to 12 degrees, 12 degrees to 15 degrees, 15 degrees to 18 degrees, and 18 degrees to 20 degrees.

[0165] During the process of rotating the door body 200 to open or close, the user pulls or pushes the door body 200 to rotate around the first hinge axis 310 and the second hinge axis 320. When the door body 200 rotates to between the second set angle and the third set angle, the door body 200 moves in the vertical direction relative to the fixed part 300 driven by the movable part 400.

[0166] During the process of rotating and opening the door body 200 , the door body 200 can rotate from the third setting angle toward the second setting angle, the opening angle of the door body 200 gradually increases, and the door body 200 moves upward in the vertical direction driven by the abutment portion 410 .

[0167] When the third setting angle is smaller, the user can feel the rising process of the door body 200 earlier during the door opening process; when the second setting angle is smaller, the user can feel the end of the rising process of the door body 200 earlier during the door opening process; and when the difference between the second setting angle and the third setting angle is smaller, the user can feel the shorter the rising process of the door body 200 is during the door opening process.

[0168] During the process of the door body 200 rotating and closing, the door body 200 can rotate from the second setting angle toward the third setting angle, the opening angle of the door body 200 gradually decreases, and the door body 200 drives the abutment portion 410 to move downward in the vertical direction.

[0169] When the second setting angle is smaller, the user can feel the descending process of the door body 200 earlier during the process of closing the door; when the third setting angle is smaller, the user can feel the end of the descending process of the door body 200 earlier during the process of opening the door; and the smaller the difference between the second setting angle and the third setting angle, the shorter the descending process of the door body 200 felt by the user during the process of opening the door.

[0170] In some embodiments, the surface of the fixed member 300 facing the movable member 400 may be provided with a first inclined portion 330 and a second inclined portion 340. The first end of the first inclined portion 330 is connected to the fixed member 300, the second end of the first inclined portion 330 is close to the movable member 400 relative to the first end of the first inclined portion 330, and the first inclined portion 330 is inclined upward.

[0171] The first end of the second inclined portion 340 is connected to the second end of the first inclined portion 330 , the second end of the second inclined portion 340 is connected to the fixing member 300 , and the second inclined portion 340 is inclined downward.

[0172] The surface of the movable member 400 facing the fixed member 300 may be provided with an abutment portion 410, which can be used to abut against the surface of the fixed member 300 facing the movable member 400. The abutment portion 410 can also be used to abut against the first inclined portion 330 and the second inclined portion 340, so that the movable member 400 drives the door body 200 to move up and down in the vertical direction through the abutment portion 410.

[0173] The height of the first inclined portion 330 may be equal to the height of the second inclined portion 340 , and the first inclined portion 330 may be connected to the second inclined portion 340 , so that the abutting portion 410 can move from the first inclined portion 330 to the second inclined portion 340 , or from the second inclined portion 340 to the first inclined portion 330 .

[0174] The first inclined portion 330 may be configured such that when the contact portion 410 contacts the first inclined portion 330 and moves from the first end of the first inclined portion 330 to the second end of the first inclined portion 330, the movable member 400 may drive the door body 200 to move upward through the contact portion 410. When the contact portion 410 contacts the first inclined portion 330 and moves from the second end of the first inclined portion 330 to the first end of the first inclined portion 330, the movable member 400 may drive the door body 200 to move downward through the contact portion 410.

[0175] The second inclined portion 340 may be configured such that when the contact portion 410 contacts the second inclined portion 340 and moves from the first end of the second inclined portion 340 to the second end of the second inclined portion 340, the movable member 400 may drive the door body 200 to move downward through the contact portion 410. When the contact portion 410 contacts the second inclined portion 340 and moves from the second end of the second inclined portion 340 to the first end of the second inclined portion 340, the movable member 400 may drive the door body 200 to move upward through the contact portion 410.

[0176] For example, when the door body 200 is in a closed state (i.e., when φ=0°), the abutting portion 410 may abut against the surface of the fixed member 300 facing the movable member 400, and the abutting portion 410 may be located on a side of the second inclined portion 340 away from the first inclined portion 330. When the door body 200 is in an open state (e.g., when φ=90°), the abutting portion 410 may abut against the surface of the fixed member 300 facing the movable member 400, and the abutting portion 410 may be located on a side of the first inclined portion 330 away from the second inclined portion 340.

[0177] During the process of rotating and opening the door body 200, the abutment portion 410 can move from the surface of the fixing member 300 to the second end of the second inclined portion 340, and move along the second end of the second inclined portion 340 to the first end of the second inclined portion 340. The movable member 400 drives the door body 200 to move upward through the abutment portion 410.

[0178] The abutment portion 410 moves from the first end of the second inclined portion 340 to the second end of the first inclined portion 330, and moves along the second end of the first inclined portion 330 to the first end of the first inclined portion 330. The movable part 400 drives the door body 200 to move downward through the abutment portion 410, so that the abutment portion 410 can move from the first end of the first inclined portion 330 to the surface of the fixing part 300 facing the movable part 400, so that the abutment portion 410 can move from the side of the second inclined portion 340 away from the first inclined portion 330 to the side of the first inclined portion 330 away from the second inclined portion 340.

[0179] During the process of rotating and closing the door body 200, the abutment portion 410 can move from the surface of the fixing member 300 to the first end of the first inclined portion 330, and move along the first end of the first inclined portion 330 to the second end of the first inclined portion 330. The movable member 400 drives the door body 200 to move upward through the abutment portion 410.

[0180] The abutment portion 410 moves from the second end of the first inclined portion 330 to the first end of the second inclined portion 340, and moves along the first end of the second inclined portion 340 to the second end of the second inclined portion 340. The movable member 400 drives the door body 200 to move downward through the abutment portion 410, so that the abutment portion 410 can move from the second end of the second inclined portion 340 to the surface of the fixing member 300 facing the movable member 400, so that the abutment portion 410 can move from the side of the first inclined portion 330 away from the second inclined portion 340 to the side of the second inclined portion 340 away from the first inclined portion 330.

[0181] It is easy to understand that when the abutment portion 410 is located on the surface of the fixing member 300, the bottom of the abutment portion 410 can abut against the surface of the fixing member 300, or the bottom of the abutment portion 410 can also be spaced apart from the surface of the fixing member 300. For example, the following description assumes that the bottom of the abutment portion 410 abuts against the surface of the fixing member 300.

[0182] The door body 200 has a certain gravity. During the process of rotating and opening the door body 200, the gravity of the door body 200 needs to be overcome so that the door body 200 can drive the abutment part 410 to move from the second end of the second inclined part 340 to the first end of the second inclined part 340, thereby the second inclined part 340 plays a certain limiting role on the abutment part 410, reducing the possibility of movement of the abutment part 410; and, during the process of rotating and closing the door body 200, when the abutment part 410 abuts against the second inclined part 340, the abutment part 410 can move toward the second end of the second inclined part 340 under the action of the gravity of the door body 200, thereby making the process of the door body 200 moving to the side of the second inclined part 340 away from the first inclined part 330 more convenient.

[0183] For example, when the abutment portion 410 moves to the side of the second inclined portion 340 away from the first inclined portion 330, the door seal located on the rear wall of the door body 200 can surround the loading and unloading opening, so that the door seal fits against the front end surface of the box body 100 to effectively seal the connection between the door body 200 and the box body 100, thereby ensuring that the door body 200 seals the loading and unloading opening through the cooperation of the gravity self-closing structure and the door seal to prevent cold air from overflowing.

[0184] Reference Figure 5-Figure 10 ,as well as Figure 15-17 In some possible embodiments, the first hinge axis 310 contacts the track groove 420 to form a first contact point, the second hinge axis 320 contacts the track groove 420 to form a second contact point, the abutment portion 410 contacts one of the first inclined portion 330 and the second inclined portion 340 to form a third contact point, and the first contact point, the second contact point and the third contact point are not colinear.

[0185] It is easy to understand that when the abutting portion 410 abuts against the first inclined portion 330 or the second inclined portion 340, the movable part 400 can abut against the fixed part 300 through three positions, namely the first contact point, the second contact point and the third contact point. The first contact point, the second contact point and the third contact point are not colinear, so that the fixed part 300 can apply a supporting force to the movable part 400 from different positions, thereby making the movement process of the movable part 400 more stable.

[0186] During the door's rotation and closing process, Fig.17 This is a schematic diagram of the positions of the first contact point, the second contact point, and the third contact point forming a triangle when the abutting portion 410 of the embodiment of the present application abuts against the first end of the first inclined portion 330 .

[0187] It should be noted that the first contact point, the second contact point and the third contact point form a triangle, the inner angle of the triangle can be greater than or equal to 20 degrees, and during the rotation and closing process of the door body, the inner angle of the triangle formed by the first contact point, the second contact point and the third contact point is greater than or equal to 20 degrees.

[0188] Since the movable part 400 is subjected to different force directions when in contact with the fixed part 300 at the first contact point, the second contact point and the third contact point, the movable part 400 can move in the horizontal direction relative to the first hinge axis 310 and the second hinge axis 320, and can also be displaced in the vertical direction relative to the first inclined portion 330 and the second inclined portion 340.

[0189] The inner angles of the triangle formed by the first contact point, the second contact point and the third contact point are all greater than or equal to 20 degrees, so that the force direction of the movable part 400 is more flexible, and the force at each position of the first contact point, the second contact point and the third contact point is relatively more uniform, thereby reducing the burden on the first hinge axis 310, the second hinge axis 320, the first inclined portion 330 and the second inclined portion 340, and reducing the possibility of deformation or breakage of any of the first hinge axis 310, the second hinge axis 320, the first inclined portion 330 and the second inclined portion 340.

[0190] In some embodiments, in the hinge assembly located at the lower end of the door body 200, the first hinge axis 310 and the second hinge axis 320 can be arranged on the surface of the fixed part 300 facing the movable part 400, and the first hinge axis 310 and the second hinge axis 320 can both extend upward in the vertical direction; and the track groove 420 can be correspondingly arranged on the surface of the movable part 400 facing the fixed part 300.

[0191] When the door body 200 is rotated to open or close, in the horizontal direction, the first hinge shaft 310 moves relative to the track groove 420 along the extension direction of the track groove 420, and the second hinge shaft 320 moves relative to the track groove 420 along the extension direction of the track groove 420. In the vertical direction, when the movable member 400 drives the door body 200 to move in the vertical direction through the abutment portion 410, the fixed member 300 is relatively fixed to the door body 200, so that the first hinge shaft 310 moves relative to the track groove 420 in the vertical direction, and the second hinge shaft 320 moves relative to the track groove 420 in the vertical direction.

[0192] For example, when the movable part 400 drives the door body 200 to move upward through the abutment portion 410, part of the first hinge shaft 310 extends out of the track groove 420, and the distance between the first hinge shaft 310 and the bottom surface of the track groove 420 increases; part of the second hinge shaft 320 extends out of the track groove 420, and the distance between the second hinge shaft 320 and the bottom surface of the track groove 420 increases.

[0193] It is easy to understand that the length of the first hinge axis 310 extending out of the track groove 420 and the length of the second hinge axis 320 extending out of the track groove 420 are equal to the distance between the second end of the first inclined portion 330, the first end of the second inclined portion 340 and the surface of the fixing member 300, and the greater the length of the first hinge axis 310 located in the track groove 420, the better the stability of the first hinge axis 310, and the greater the length of the second hinge axis 320 located in the track groove 420, the better the stability of the second hinge axis 320.

[0194] For example, when the distance between the second end of the first inclined portion 330, the first end of the second inclined portion 340 and the surface of the fixed member 300 remains unchanged, the stability of the first hinge axis 310 in the track groove 420 can be improved by increasing the length of the first hinge axis 310 and the depth of the track groove 420, and the stability of the second hinge axis 320 in the track groove 420 can be improved by increasing the length of the second hinge axis 320 and the depth of the track groove 420, so as to reduce the possibility of the movable member 400 being separated from the fixed member 300.

[0195] An angle between a line connecting the first hinge axis 310 and the second hinge axis 320 and an arrangement direction of the first inclined portion 330 and the second inclined portion 340 may be set to be greater than or equal to 0 degrees and less than or equal to 45 degrees.

[0196] For example, the angle between the line between the first hinge axis 310 and the second hinge axis 320 and the arrangement direction of the first inclined portion 330 and the second inclined portion 340 can be set to one of 0 degrees-5 degrees, 5 degrees-10 degrees, 10 degrees-15 degrees, 15 degrees-20 degrees, 20 degrees-25 degrees, 25 degrees-30 degrees, 30 degrees-35 degrees, 35 degrees-40 degrees, and 40 degrees-45 degrees.

[0197] In some embodiments, the position of the first inclined portion 330 and the position of the second inclined portion 340 may be determined according to the opening angle of the door body 200 .

[0198] For example, when the opening angle φ of the door body 200 is set to: 15 degrees ≤ φ ≤ 25 degrees, the abutting portion 410 abuts against the first inclined portion 330. When the opening angle φ of the door body 200 = 25 degrees, the opening angle of the door body 200 is set to the first set angle.

[0199] The abutting portion 410 abuts against the first end of the first inclined portion 330 . When the opening angle φ of the door body 200 is 15 degrees, the opening angle of the door body 200 is set to the second set angle, and the abutting portion 410 abuts against the second end of the first inclined portion 330 .

[0200] When the opening angle φ of the door body 200 is set to: 5 degrees ≤ φ < 15 degrees, the abutting portion 410 abuts against the second inclined portion 340 . When the opening angle φ of the door body 200 is 5 degrees, the opening angle of the door body 200 is set to the third set angle.

[0201] The contact portion 410 contacts the second end of the second inclined portion 340 . When the opening angle φ of the door body 200 is 15 degrees, the contact portion 410 can move from the second end of the first inclined portion 330 toward the first end of the second inclined portion 340 .

[0202] During the process of the door body 200 rotating and closing, when the opening angle φ of the door body 200 is greater than 25 degrees, the abutting portion 410 abuts against the surface of the fixing member 300, and the abutting portion 410 is located on the side of the first inclined portion 330 away from the second inclined portion 340. When the opening angle φ of the door body 200 is 25 degrees, the abutting portion 410 can move from the surface of the fixing member 300 to the first end of the first inclined portion 330. When the opening angle φ of the door body 200 is set to: 15 degrees ≤ φ ≤ 25 degrees, the abutting portion 410 abuts against the first inclined portion 330, and the movable member 400 drives the door body 200 to move upward through the abutting portion 410.

[0203] When the opening angle φ of the door body 200 is 15 degrees, the abutment portion 410 can move from the second end of the first inclined portion 330 to the first end of the second inclined portion 340; when the opening angle φ of the door body 200 is set to: 5 degrees ≤ φ < 15 degrees, the abutment portion 410 abuts against the second inclined portion 340, and the door body 200 can drive the abutment portion 410 to move downward under the action of gravity, so as to drive the abutment portion 410 to move to the second end of the second inclined portion 340; when the opening angle φ of the door body 200 is 5 degrees, the abutment portion 410 abuts against the second end of the second inclined portion 340, and the door seal located on the rear wall of the door body 200 fits against the front end surface of the box body 100 to effectively seal the connection between the door body 200 and the box body 100.

[0204] It should be noted that if the user pushes the door body 200 to rotate and close the door body 200, the door body 200 will have a jumping process of first upward and then downward when the abutting portion 410 abuts against the first inclined portion 330 and the second inclined portion 340 in sequence, thereby causing the user to have a certain sense of frustration. The distance between the second end of the first inclined portion 330, the first end of the second inclined portion 340 and the surface of the fixing member 300 can be adjusted to change the moving distance of the door body 200 in the vertical direction, thereby reducing the user's sense of frustration during the door closing process and improving the user's experience.

[0205] For example, the first setting angle, the second setting angle and the third setting angle of the door body 200 can be changed by adjusting the position and length of the first inclined portion 330 and the second inclined portion 340 to change the moving time of the door body 200 in the vertical direction. For example, when the length of the first inclined portion 330 increases, the moving time of the door body 200 in the vertical direction increases, and the difference between the second setting angle and the first setting angle increases; when the length of the second inclined portion 340 increases, the moving time of the door body 200 in the vertical direction increases, and the difference between the third setting angle and the second setting angle increases; and when the distance between the second end of the first inclined portion 330, the first end of the second inclined portion 340 and the surface of the fixing member 300 remains unchanged, the inclination angle of the first inclined portion 330 decreases, and the inclination angle of the second inclined portion 340 increases.

[0206] In addition, the position of the first set angle of the door body 200 can be changed by adjusting the position of the first end of the first inclined portion 330, and the position of the third set angle of the door body 200 can be adjusted by adjusting the position of the second end of the second inclined portion 340 to determine the movement time of the door body 200 in the vertical direction.

[0207] For example, the length of the first inclined portion 330 may be equal to the length of the second inclined portion 340, so that the inclination angle of the first inclined portion 330 is equal to the inclination angle of the second inclined portion 340. Alternatively, the length of the first inclined portion 330 may be greater than the length of the second inclined portion 340, so that the inclination angle of the first inclined portion 330 is smaller than the inclination angle of the second inclined portion 340. Alternatively, the length of the first inclined portion 330 may be smaller than the length of the second inclined portion 340, and the inclination length of the first inclined portion 330 is greater than the inclination angle of the second inclined portion 340.

[0208] For example, when the opening angle φ of the door body 200 is set to: 15 degrees ≤ φ ≤ 45 degrees, the abutting portion 410 abuts against the first inclined portion 330; when the opening angle φ of the door body 200 is 45 degrees, the opening angle of the door body 200 is set to the first set angle, and the abutting portion 410 abuts against the first end of the first inclined portion 330; when the opening angle φ of the door body 200 is 15 degrees, the opening angle of the door body 200 is set to the second set angle, and the abutting portion 410 abuts against the first inclined portion 330. the second end of the door body 200; when the opening angle φ of the door body 200 is set to: 8 degrees ≤ φ < 15 degrees, the abutment portion 410 abuts against the second inclined portion 340, and when the opening angle φ of the door body 200 is 8 degrees, the opening angle of the door body 200 is set to a third set angle, and the abutment portion 410 abuts against the second end of the second inclined portion 340, and when the opening angle φ of the door body 200 is 15 degrees, the abutment portion 410 can move from the second end of the first inclined portion 330 toward the first end of the second inclined portion 340.

[0209] In some embodiments, reference Figure 2 The abutting portion 410 may be provided with a first abutting surface 411 and a second abutting surface 412 connected to each other, and the first abutting surface 411 and the second abutting surface 412 are both inclined relative to the vertical direction.

[0210] When the door body 200 is in a closed state (i.e., when φ=0°), the bottom of the abutment portion 410 can abut against the surface of the fixed member 300 facing the movable member 400, and the abutment portion 410 can be located on the side of the second inclined portion 340 away from the first inclined portion 330; when the door body 200 is in an open state (for example, when φ=90°), the bottom of the abutment portion 410 can abut against the surface of the fixed member 300 facing the movable member 400, and the abutment portion 410 is located on the side of the first inclined portion 330 away from the second inclined portion 340.

[0211] In the first abutting surface 411 and the second abutting surface 412 , the first abutting surface 411 is used to abut the inclined surface of the first inclined portion 330 , the second abutting surface 412 is used to abut the inclined surface of the second inclined portion 340 , and the bottom end of the first abutting surface 411 is connected to the bottom end of the second abutting surface 412 .

[0212] During the process of rotating and opening the door body 200, the bottom of the abutment portion 410 can move from the surface of the fixing member 300 to the second end of the second inclined portion 340, and the second abutment surface 412 can move along the second end of the second inclined portion 340 to the first end of the second inclined portion 340, and the movable member 400 drives the door body 200 to move upward through the abutment portion 410; and the bottom of the abutment portion 410 moves from the first end of the second inclined portion 340 to the second end of the first inclined portion 330 through the arc surface, and the first abutment surface 411 can move along the second end of the first inclined portion 330 to the first end of the first inclined portion 330, and the movable member 400 drives the door body 200 to move downward through the abutment portion 410, so that the abutment portion 410 can move from the first end of the first inclined portion 330 to the surface of the fixing member 300 facing the movable member 400, so that the abutment portion 410 can move from the side of the second inclined portion 340 away from the first inclined portion 330 to the side of the first inclined portion 330 away from the second inclined portion 340.

[0213] During the process of rotating and closing the door body 200, the bottom of the abutment portion 410 can move from the surface of the fixing member 300 to the first end of the first inclined portion 330, the first abutment surface 411 moves along the first end of the first inclined portion 330 to the second end of the first inclined portion 330, and the movable member 400 drives the door body 200 to move upward through the abutment portion 410; and the bottom of the abutment portion 410 moves from the second end of the first inclined portion 330 to the first end of the second inclined portion 340 through the arc surface, the second abutment surface 412 moves along the first end of the second inclined portion 340 to the second end of the second inclined portion 340, and the movable member 400 drives the door body 200 to move downward through the abutment portion 410, so that the abutment portion 410 can move from the second end of the second inclined portion 340 to the surface of the fixing member 300 facing the movable member 400, so that the abutment portion 410 can move from the side of the first inclined portion 330 away from the second inclined portion 340 to the side of the second inclined portion 340 away from the first inclined portion 330.

[0214] For example, in a vertical plane, the first abutment surface 411 can be arranged parallel to the inclined surface of the first inclined portion 330, and the second abutment surface 412 can be arranged parallel to the inclined surface of the second inclined portion 340, so as to increase the fitting area between the first abutment surface 411 and the first inclined portion 330 and the fitting area between the second abutment surface 412 and the second inclined portion 340, thereby improving the stability of the bottom end of the abutment portion 410 moving along the moving path during the rotation and closing of the door body 200.

[0215] When the bottom of the abutment portion 410 is located at the connection between the surface of the fixing member 300 and the first end of the first inclined portion 330, the first abutment surface 411 is in contact with the first inclined portion 330. When the abutment portion 410 moves from the first end of the first inclined portion 330 toward the second end of the first inclined portion 330, the area in which the first abutment surface 411 is in contact with the first inclined portion 330 gradually decreases. When the abutment portion 410 moves to the second end of the first inclined portion 330, the first abutment surface 411 is completely separated from the first inclined portion 330, and the bottom of the abutment portion 410 abuts against the arc surface.

[0216] When the bottom of the abutting portion 410 moves to the first end of the second inclined portion 340 and moves from the first end of the second inclined portion 340 toward the second end of the second inclined portion 340, the area of ​​the second abutting surface 412 fitting with the second inclined portion 340 gradually increases. When the abutting portion 410 moves to the second end of the second inclined portion 340, the fitting area between the second abutting surface 412 and the second inclined portion 340 is the largest, and the bottom of the abutting portion 410 abuts against the surface of the fixed part 300 facing the movable part 400.

[0217] When the inclination angle of the first inclined portion 330 is equal to the inclination angle of the second inclined portion 340, the inclination angle of the first abutting surface 411 can be equal to the inclination angle of the second abutting surface 412; when the inclination angle of the first inclined portion 330 is smaller than the inclination angle of the second inclined portion 340, the inclination angle of the first abutting surface 411 can be correspondingly smaller than the inclination angle of the second inclined portion 340, so as to increase the fitting area between the first abutting surface 411 and the first inclined portion 330 and the fitting area between the second abutting surface 412 and the second inclined portion 340.

[0218] For example, the inclination angle of the second inclined portion 340 can also be greater than the inclination angle of the first inclined portion 330. When the door body 200 is in a closed state (i.e., when φ=0°), the larger the inclination angle of the second inclined portion 340, the more difficult it is for the second abutment surface 412 to move from the first end of the second inclined portion 340 to the second end of the second inclined portion 340, and the tighter the connection between the door body 200 and the box body 100. Therefore, the sealing of the closed loading and unloading port of the door body 200 can be improved by adjusting the inclination angle of the second inclined portion 340.

[0219] In some embodiments, the inclined surface of the first inclined portion 330 and the inclined surface of the second inclined portion 340 can be set in the same vertical plane as the moving path, that is, the inclined surface of the first inclined portion 330 and the inclined surface of the second inclined portion 340 are both facing the vertical direction; or, the inclined surface of the first inclined portion 330 and the inclined surface of the second inclined portion 340 can also face the first hinge axis 310 and the second hinge axis 320. When the movable part 400 rotates relative to the fixed part 300 through the first hinge axis 310 and the second hinge axis 320, the abutment portion 410 can abut against the surfaces of the first inclined portion 330 and the second inclined portion 340 facing the first hinge axis 310 and the second hinge axis 320.
