[0048] The present application will be described in detail below with reference to the specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and the structural, method, or functional changes made by those of ordinary skill in the art based on these embodiments are included in the protection scope of the present application.

[0049] In various views of the present application, certain dimensions of structures or parts are exaggerated relative to other structures or parts for ease of illustration, and thus, are used only to illustrate the basic structure of the subject matter of the present application.

[0050] Referring to FIG. 1, a schematic view of an appliance 100 according to an embodiment of the present application is shown. Figure 1

[0051] The appliance 100 includes a cabinet 10, a door 20, and a hinge assembly 30 connecting the cabinet 10 and the door 20.

[0052] It should be noted that the appliance 100 can be a refrigerator, a freezer, a wine cabinet, etc., and here, the appliance 100 is taken as an example of a refrigerator.

[0053] In addition, the hinge assembly 30 is not only applicable to the appliance 100, but also applicable to other scenarios, such as a cabinet, a wardrobe, etc., and the present application takes the hinge assembly 30 applied to the refrigerator 100 as an example for illustration, but is not limited thereto.

[0054] Referring to FIG. 2, a schematic view of the hinge assembly 30 according to an embodiment of the present application is shown. Figures 2 to 4

[0055] ​​The hinge assembly 30 comprises a first hinge member 31 connecting the cabinet 10, a second hinge member 32 connecting the door 20, and a sliding piece 40 connecting the first hinge member 31 and the second hinge member 32.

[0056] Here, the first hinge member 31 connecting the cabinet 10 means that the first hinge member 31 is connected to the cabinet 10. The first hinge member 31 can be a separate component mounted to the cabinet 10, or can be a component integrally formed on the cabinet 10.

[0057] Similarly, the second hinge member 32 connecting the door 20 means that the second hinge member 32 is connected to the door 20. The second hinge member 32 can be a separate component mounted to the door 20, or can be a component integrally formed on the door 20.

[0058] The hinge assembly 30 further comprises two shafts 311, 312 of the first hinge member 31, two grooves 401, 402 of the sliding piece 40, a limiting groove 322 of the second hinge member 32, and a rotating assembly 50 between the sliding piece 40 and the second hinge member 32.

[0059] When the hinge assembly 30 is in a closed state, one of the shafts 312 extends into one of the grooves 402 and the limiting groove 322 which are mutually overlapped, and the central axis of the shaft 312 when rotating does not coincide with the central axis of the rotating assembly 50 when rotating. The other shaft 311 extends into the other groove 401, and the other shaft 311 is located on the side of the second hinge member 32 close to the sliding piece 40. The sliding piece 40 and the second hinge member 32 are relatively stationary, and when the hinge assembly 30 is in an opening process, the second hinge member 32 moves together with the sliding piece 40 relative to the first hinge member 31 until the shafts 311, 312 are limited in the grooves 401, 402, and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40.

[0060] Here, "mutually overlapped" means that the groove 402 and the limiting groove 322 have the same shape. "The other shaft 311 is located on the side of the second hinge member 32 close to the sliding piece 40" means that the shaft 311 does not extend into the second hinge member 32, i.e. the end of the shaft 311 close to the second hinge member 32 is located above the second hinge member 32 (i.e. on the side of the second hinge member 32 close to the sliding piece 40). The shaft 311 is not connected to the second hinge member 32 itself, but can be connected to the second hinge member 32 through other structures, such as the protruding part 326 and the sliding groove 404 described later.

[0061] Here, the "two shaft bodies 311, 312 located on the first hinge piece 31" means that the two shaft bodies 311, 312 are arranged on the first hinge piece 31, and the shaft bodies 311, 312 and the first hinge piece 31 can be integrally formed or assembled into one body. The explanation of "located" in other parts of the present application can refer to the above description, and the subsequent description will not be repeated.

[0062] It should be noted that the "hinge assembly 30 in the opening process" means that the second hinge piece 32 is opened in a direction away from the first hinge piece 31, that is, the second hinge piece 32 is driven to move in a direction away from the first hinge piece 31 by acting on the second hinge piece 32 in one direction. When the hinge assembly 30 is installed on the refrigerator 100, the opening process of the hinge assembly 30 corresponds to the opening process of the door body 20.

[0063] In the present embodiment, the second hinge piece 32 moves together with the sliding piece 40 relative to the first hinge piece 31 first, and then the rotating assembly 50 drives the second hinge piece 32 to move relative to the sliding piece 40. It can be seen that in the entire opening process of the hinge assembly 30, two movements are realized, and the change of the rotating shaft position can be realized in the two movement processes, which can effectively control the movement trajectory of the door body, thereby improving the degree of freedom of the opening and closing process of the door body 20 of the refrigerator 100. In particular, in the field of embedded refrigerators, the switching of the rotating shaft can avoid the mutual interference between the door body 20 and the surrounding cabinet or wall during the opening and closing process.

[0064] In the present embodiment, the hinge assembly 30 includes the first shaft body 311 and the second shaft body 312 arranged on the first hinge piece 31, and the first slot body 401 and the second slot body 402 arranged on the sliding piece 40. The first slot body 401 cooperates with the first shaft body 311, and the second slot body 402 cooperates with the second shaft body 312.

[0065] Here, the second shaft body 312 extends to the second slot body 402 and the first shaft body 311 extends to the first slot body 401, which are taken as examples for illustration.

[0066] In the present embodiment, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the second hinge piece 32 and the sliding piece 40 rotate relative to the first hinge piece 31 with the first rotating shaft P1 as the center axis. When the hinge assembly 30 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the second hinge piece 32 rotates relative to the sliding piece 40 with the second rotating shaft P2 as the center axis. The second rotating shaft P2 and the first rotating shaft P1 are staggered, that is, the position of the second rotating shaft P2 is inconsistent with the position of the first rotating shaft P1.

[0067] Here, the first rotating shaft P1 can be a virtual shaft or a physical shaft.

[0068] A virtual axis refers to an axis that does not actually exist in the hinge assembly 30, while a physical axis refers to a component that is actually included in the hinge assembly 30.

[0069] In addition, the first rotating shaft P1 can be a non-fixed shaft or a fixed shaft.

[0070] A non-fixed shaft refers to a shaft whose position is constantly changing, meaning that the relative position between the first rotating shaft P1 and the housing 10 or the door 20 is changing. A fixed shaft, on the other hand, refers to a shaft whose position is fixed, meaning that the relative position between the first rotating shaft P1 and the housing 10 or the door 20 is fixed.

[0071] Similarly, the second rotation axis P2 can be a virtual axis or a physical axis, and the second rotation axis P2 can be a non-fixed axis or a fixed axis. The second rotation axis P2 is offset from the first rotation axis P1, that is, the position of the second rotation axis P2 is not the same as the position of the first rotation axis P1.

[0072] As can be seen, the hinge assembly 30 of this embodiment can effectively control the order of the two rotations. During the two rotations, there is a change in the position of the rotation axis, which can effectively control the movement trajectory of the door 20, thereby improving the degree of freedom of the opening and closing process of the refrigerator 100 door 20. Especially in the field of built-in refrigerators, the switching of the rotation axis can avoid the door 20 from interfering with the surrounding cabinets or walls during the opening and closing process.

[0073] To further illustrate the movement trajectory of the hinge assembly 30, combined with Figure 5 The following is an example of a simplified diagram showing the hinge assembly 30 assembled to the refrigerator 100 and the refrigerator 100 embedded in the cabinet 200.

[0074] The housing 10 includes an opening 102 and a front end face 103 surrounding the opening 102. The housing 10 also includes a receiving chamber D and an outer side face 13 adjacent to the hinge assembly 30 and extending along the rotation path of the door 20. The door 20 includes a front wall 21 away from the receiving chamber D and a side wall 22 that is always sandwiched between the front wall 21 and the receiving chamber D. A side ridge 23 is provided between the front wall 21 and the side wall 22.

[0075] The hinge assembly 30 is configured such that when the first rotating shaft P1 is actuated, there is a first distance between the first rotating shaft P1 and the front end face 103 of the housing 10, and when the second rotating shaft P2 is actuated, there is a second distance between the second rotating shaft P2 and the front end face 103 of the housing 10, the second distance being greater than the first distance.

[0076] In addition, when the first rotating shaft P1 is actuated, there is a third distance between the first rotating shaft P1 and the outer side surface 13 of the housing 10, and when the second rotating shaft P2 is actuated, there is a fourth distance between the second rotating shaft P2 and the outer side surface 13 of the housing 10, and the fourth distance is less than the third distance.

[0077] Here, the "first rotation axis P1 actuation" refers to the first rotation axis P1 being in a working state, i.e., at this time the second hinge member 32 rotates relative to the first hinge member 31 together with the sliding sheet 40, and similarly, the "second rotation axis P2 actuation" refers to the second rotation axis P2 being in a working state, i.e., at this time the second hinge member 32 rotates relative to the sliding sheet 40.

[0078] It should be noted that the above distance refers to the distance between the first rotation axis P1, the second rotation axis P2 and the front end face 103, the outer side face 13 of the cabinet 10 when the hinge assembly 30 moves to a certain position, rather than the distance in the closed state.

[0079] The specific description is as follows:

[0080] In actual operation, in order to improve the embedding effect, it is preferable to make the refrigerator 100 completely embedded into the cabinet 200, and the refrigerator 100 is a free-embedded refrigerator, i.e., the front end 201 of the cabinet 200 and the front wall 21 of the door body 20 away from the cabinet 10 are located in the same plane, or the front wall 21 of the door body 20 does not protrude out of the front end 201 of the cabinet 200 at all.

[0081] In the prior art, the refrigerator is a single-axis refrigerator, and a certain distance needs to be maintained between the rotation axis of the refrigerator and the side wall and the front wall of the refrigerator, so that there is enough space to meet the foaming or other processes, i.e., the position of the rotation axis of the existing refrigerator is approximately at the position of the single-axis shaft body P3 in Figure 5 In this case, after embedding the single-axis refrigerator into the cabinet 200, since the corner 203 between the front end 201 and the inner wall 202 of the cabinet 200 is correspondingly arranged with the side corner 23 of the door body 20, when the door body 20 is opened, the side corner 23 will interfere with the door body 20 to limit the maximum opening angle of the door body 20, and in order to ensure the normal opening of the door body 20, the prior art usually increases the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, which is approximately about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

[0082] In combination with Figure 5 , the shaded area represents the door body 20 in the closed state, when the door body 20 is in the opening process, if the door body 20 always rotates around the single-axis shaft body P3 as the center axis (i.e., the prior art), referring to the dotted line door body 20' in Figure 5 , since the single-axis shaft body P3 is close to the front end face 103, i.e., at this time the single-axis shaft body P3 is away from the front end 201 of the cabinet 200, when the door body 20' is opened to a certain angle, the corner 203 of the cabinet 200 will interfere with the door body 20' to limit the maximum opening angle of the door body 20'.

[0083] In the embodiment, the door body 20 first rotates around the first rotation axis P1 as the center axis, specifically, the second hinge part 32 and the sliding piece 40 rotate together relative to the first hinge part 31 by a certain angle, with the change of the positions of the second hinge part 32 and the sliding piece 40, the relative position of the second rotation axis P2 to the cabinet 10 also changes, the second rotation axis P2 gradually moves away from the front end face 103, that is, the second rotation axis P2 gradually moves towards the front end 201 of the cabinet 200, at this time, the door body 20 rotates around the second rotation axis P2 at the current position as the center axis, since the second rotation axis P2 at this time is farther away from the front end face 103 of the cabinet 10 than the first rotation axis P1, with reference to the solid line door body 20 in Figure 5 , the interference of the cabinet 200 edges 203 to the door body 20 is greatly reduced, the door body 20 is opened to a larger angle before the cabinet 200 edges 203 interfere with each other, thereby greatly improving the maximum opening angle of the door body 20.

[0084] That is, the door body 20 of the embodiment switches to rotate around the second rotation axis P2 as the center axis after being opened to a certain angle, under the premise of ensuring that the refrigerator 100 is freely embedded into the cabinet 200, the maximum opening angle of the door body 20 can be effectively improved, thereby facilitating the user to operate the refrigerator 100, and the user experience can be greatly improved.

[0085] Moreover, the embodiment does not need to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, and the seamless connection of the refrigerator 100 and the cabinet 200 can be achieved, thereby greatly improving the embedding effect.

[0086] In addition, the second rotation axis P2 of the embodiment gradually moves towards the front end 201 of the cabinet 200 while gradually moving close to the inner wall 202 of the cabinet 200, that is, when the door body 20 rotates around the second rotation axis P2 as the center axis, the second rotation axis P2 at this time is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first rotation axis P1, in this way, the maximum opening angle of the door body 20 can be improved, and the door body 20 can be moved away from the cabinet 10 to increase the opening degree of the cabinet 10, thereby facilitating the opening and closing of the shelves, drawers and the like in the cabinet 10, or in other words, facilitating the taking and placing of articles.

[0087] Of course, the second rotation axis P2 as the center axis can also be located at other positions, for example, when the door body 20 rotates around the second rotation axis P2 as the rotation axis, the second rotation axis P2 at this time is closer to the front end 201 of the cabinet 200 than the first rotation axis P1, and the second rotation axis P2 at this time is farther away from the inner wall 202 of the cabinet 200 than the first rotation axis P1, and the like.

[0088] It can be understood that the sliding sheet 40 controls the switching sequence of the first hinge member 31 and the second hinge member 32 in the opening and closing process of the door body 20, which can effectively avoid the mutual interference between the door body 20 and the cabinet 200 in the opening and closing process.

[0089] In the embodiment, the hinge assembly 30 further comprises a second slot body 402 and a limiting slot 322. Figures 2 to 5 The hinge assembly 30 further comprises a second slot body 402 and a limiting slot 322.

[0090] The second slot body 402 is a circular arc slot, and the center axis of the circular arc slot is the second rotation axis P2.

[0091] Here, the second hinge member 32 and the sliding sheet 40 are substantially connected through two parts, one part is the connection of the rotating assembly 50, and the other part is the second slot body 402 and the limiting slot 322. Since the center axis of the limiting slot 322 is the first rotation axis P1 when rotating, and the center axis of the rotating assembly 50 is the second rotation axis P2 when rotating, the second hinge member 32 cannot rotate at the same time with the first rotation axis P1 and the second rotation axis P2 being inconsistent in position, that is, when the second shaft body 312 rotates in the limiting slot 322, the rotating assembly 50 cannot drive the second hinge member 32 to rotate relative to the sliding sheet 40, that is, the second hinge member 32 and the sliding sheet 40 are relatively static at this time.

[0092] Specifically, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the second shaft body 312 is located in the limiting slot 322. Due to the limiting effect of the second shaft body 312 on the limiting slot 322, the second hinge member 32 cannot rotate relative to the sliding sheet 40 with the second rotation axis P2 as the center axis, that is, the second hinge member 32 and the sliding sheet 40 are relatively static. At this time, through the movement of the second shaft body 312 in the second slot body 402 and the limiting slot 322, the second hinge member 32 and the sliding sheet 40 can rotate together relative to the first hinge member 31 until the first shaft body 311 is limited in the first slot body 401 and / or the second shaft body 312 is limited in the second slot body 402. At this time, the sliding sheet 40 cannot continue to rotate relative to the first hinge member 31, and the first hinge member 31 and the sliding sheet 40 are locked.

[0093] Then, when the hinge assembly 30 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, since the hinge assembly 30 further comprises the accommodation slot 324 communicating with the limiting slot 322, the second shaft body 312 can move in the accommodation slot 324 with the second rotation axis P2 as the center axis, which can drive the second hinge member 32 to rotate relative to the sliding sheet 40. At the same time, since the first shaft body 311 is spaced apart from the second hinge member 32, the first shaft body 311 will not hinder the rotation of the second hinge member 32 relative to the sliding sheet 40.

[0094] It can be understood that in other embodiments, the second hinge member 32 and the sliding sheet 40 can be kept relatively static during the process of opening from the closed state to the first opening angle a1 by adding other structures.

[0095] In addition, the second hinge member 32 and the sliding sheet can be locked by the cooperation of the second shaft body 312 and the rotating assembly 50, so that the structure of the second hinge member 32 can be simplified, and the overall structure of the hinge assembly 30 can be miniaturized.

[0096] In the embodiment, the second rotating shaft P2 is a fixed shaft, and the second hinge member 32 rotates relative to the sliding sheet 40 around the second rotating shaft P2.

[0097] The second rotating shaft P2 can be a virtual shaft or a physical shaft, which can be determined according to actual conditions.

[0098] In the embodiment, the rotating assembly 50 includes a third shaft body 403 and a circular hole 325 between the sliding sheet 40 and the second hinge member 32, and the third shaft body 403 rotates in the circular hole 325 as the second rotating shaft P2. Figures 2 to 5 Here, the second rotating shaft P2 is a physical shaft, the third shaft body 403 is located on the side of the sliding sheet 40 close to the second hinge member 32, the circular hole 325 is located on the second hinge member 32, and when the second hinge member 32 rotates relative to the sliding sheet 40, the third shaft body 403 rotates in the circular hole 325, and the second shaft body 312 slides in the displacement slot 324.

[0099] In addition, the rotating assembly 50 further includes a protruding part 326 and a sliding groove 404 between the sliding sheet 40 and the second hinge member 32, and the protruding part 326 slides in the sliding groove 404 around the second rotating shaft P2 as the center axis.

[0100] At this time, when the second hinge member 32 rotates relative to the sliding sheet 40, the third shaft body 403 rotates in the circular hole 325, and the protruding part 326 slides in the sliding groove 404 around the second rotating shaft P2 as the center axis, so that the stability of the rotation of the second hinge member 32 relative to the sliding sheet 40 can be improved.

[0101] In addition, when the protruding part 326 slides in the sliding groove 404 to the end of the sliding groove 404 (i.e., when the protruding part 326 slides to the limit position), the first hinge member 32 cannot continue to rotate relative to the sliding sheet 40, that is, the length of the sliding groove 404 can be used to control the maximum opening angle of the door body 20, but not limited thereto.

[0102]

[0103] ​In the embodiment, since the positioning effect of the displacement slot 324 on the second shaft body 312 is not good, when the rotating assembly 50 only includes the third shaft body 403 and the circular hole 325, the phenomenon of mutual shaking between the second hinge piece 32 and the sliding sheet 40 may exist. In order to avoid this phenomenon, the rotating assembly 50 is further provided with the protruding part 326 and the sliding groove 404, which can assist the second hinge piece 32 to stably rotate relative to the sliding sheet 40.

[0104] In the embodiment, the protruding part 326 is located on the second hinge piece 32, and the protruding part 326 is a convex rib 326. The sliding groove 404 is located on the sliding sheet 40, and the sliding groove 404 penetrates the first groove body 401 and / or the second groove body 402.

[0105] Here, the convex rib 326 is a circular arc-shaped convex rib with a certain length, the sliding groove 404 is a circular arc groove with the second rotating shaft P2 as the center shaft, and "the sliding groove 404 penetrates the first groove body 401 and / or the second groove body 402" means that the extension track of the sliding groove 404 is communicated with the first groove body 401 and / or the second groove body 402, and the convex rib 326 can slide in the sliding groove 404 to enter the first groove body 401 and / or the second groove body 402.

[0106] When the sliding groove 404 penetrates the first groove body 401, the convex rib 326 moves in the sliding groove 404 to pass through the first groove body 401. The convex rib 326 cooperates with the first groove body 401 to limit the first shaft body 311. Specifically, the convex rib 326 cooperates with the end of the first groove body 401 to limit the first shaft body 311, and the convex rib 326 is tangent to the outer contour of the first shaft body 311.

[0107] In other embodiments, in combination with Figures 6 to 10 The first shaft body 311 has a first gap 3111 cooperating with the convex rib 326. When the convex rib 326 slides to the first groove body 401, the convex rib 326 passes through the first gap 3111 to directly limit the first shaft body 311.

[0108] When the sliding groove 404 penetrates the second groove body 402, the convex rib 326 moves in the sliding groove 404 to pass through the second groove body 402. The convex rib 326 cooperates with the second groove body 402 to limit the second shaft body 312. Specifically, the convex rib 326 cooperates with the end of the second groove body 402 to limit the second shaft body 312, and the convex rib 326 is tangent to the outer contour of the second shaft body 312.

[0109] In other embodiments, the second shaft body 312 has a second gap 3121 cooperating with the convex rib 326. When the convex rib 326 slides to the second groove body 402, the convex rib 326 passes through the second gap 3121 to directly limit the second shaft body 312.

[0110] It can be understood that when the door body 20 is closed from the maximum opening angle, if the first shaft body 311 and the second shaft body 312 are not limited at this time, the first shaft body 311 may move back in the first groove 401, the second shaft body 312 may move back in the second groove 402, that is, the reset movement of the second hinge piece 32 may be earlier than the reset movement of the slide piece 40, so that there is a risk that the movement track of the door body 20 when closed is not controlled.

[0111] The present embodiment realizes the limiting of the first shaft body 311 and / or the second shaft body 312 through the cooperation of the convex rib 326 and the sliding groove 404, so that when the door body 20 is closed from the maximum opening angle, the slide piece 40 can only rotate when the first shaft body 311 and the second shaft body 312 are disengaged from the limiting of the convex rib 326, that is, when the door body 20 is closed from the maximum opening angle, the second hinge piece 32 is first driven to reset through the movement of the convex rib 326 in the sliding groove 404 until the convex rib 326 is disengaged from the first groove 401 and / or the second groove 402, and the limiting groove 322 overlaps the second groove 402, and then the second hinge piece 32 is driven to reset together with the slide piece 40 through the movement of the first shaft body 311 in the first groove 401 and the movement of the second shaft body 312 in the second groove 402 and the limiting groove 322.

[0112] Next, various specific examples of the protruding portion 326 and the sliding groove 404 are introduced.

[0113] In the first specific example, in combination with Figure 6 , the convex rib 326 is located on the side surface of the second hinge piece 32 close to the slide piece 40, the sliding groove 404 only penetrates the second groove 402, and the sliding groove 404 extends to both sides of the second groove 402, the convex rib 326 moves in the sliding groove 404 to pass through the second groove 402, and the convex rib 326 cooperates with the end of the second groove 402 to limit the second shaft body 312, that is, a part of the second shaft body 312 abuts against the end of the second groove 402, and another part of the second shaft body 312 is tangent to the convex rib 326.

[0114] It should be noted that when the convex rib 326 slides to the end of the sliding groove 404, part of the convex rib 326 is still located in the second groove 402 to limit the second shaft body 312.

[0115] In the second specific example, in combination with Figure 7 and Figure 8The convex rib 326 is located in the slot 324, the sliding groove 404 only penetrates the second groove 402, and the sliding groove 404 extends to both sides of the second groove 402. The second shaft body 312 has a second notch 3121 on the side away from the first hinge part 31. The second notch 3121 overlaps the sliding groove 404. The convex rib 326 passes through the sliding groove 404 and the second notch 3121 at the same time. When the convex rib 326 slides to the end of the sliding groove 404, part of the convex rib 326 is located in the second notch 3121 to limit the second shaft body 312.

[0116] In a third specific example, in combination with Figure 9 and Figure 10 The convex rib 326 includes a first convex rib 3261 on the side surface of the second hinge part 32 close to the sliding sheet 40 and a second convex rib 3262. The sliding groove 404 includes a first sliding groove 4041 penetrating the first groove 401 and a second sliding groove 4042 penetrating the second groove 402. The first sliding groove 4041 and the second sliding groove 4042 are staggered with each other. The first sliding groove 4041 extends to both sides of the first groove 401, and the second sliding groove 4042 extends to both sides of the second groove 402. The first convex rib 3261 moves in the first sliding groove 4041 to pass through the first groove 401. The first convex rib 3261 is limited by the end of the first groove 401, that is, part of the first shaft body 311 abuts against the end of the first groove 401, and the other part of the first shaft body 311 is tangent to the first convex rib 3261. At the same time, the second convex rib 3262 moves in the second sliding groove 4042 to pass through the second groove 402. The second convex rib 3262 is limited by the end of the second groove 402, that is, part of the second shaft body 312 abuts against the end of the second groove 402, and the other part of the second shaft body 312 is tangent to the second convex rib 3262.

[0117] It should be noted that when the first convex rib 3261 slides to the end of the first sliding groove 4041, part of the first convex rib 3261 is still located in the first groove 401 to limit the first shaft body 311. At the same time, when the second convex rib 3262 slides to the end of the second sliding groove 4042, part of the second convex rib 3262 is still located in the second groove 402 to limit the second shaft body 312.

[0118] In other embodiments, the protruding part 326 and the sliding groove 404 can have other structures.

[0119] For example, in combination with Figure 11 and Figure 12 The protruding part 326 is located in the second hinge part 32. The protruding part 326 is a convex column 326. The sliding groove 404 is located in the sliding sheet 40. The sliding groove 404 is staggered with the first groove 401, and the sliding groove 404 is staggered with the second groove 402.

[0120] At this time, when the second hinge part 32 rotates relative to the sliding piece 40, the convex column 326 slides in the sliding groove 404 until the convex column 326 abuts against the end of the sliding groove 404, and the sliding groove 404 and the setting position of the convex column 326 can be interchanged.

[0121] Of course, in addition to the protrusion 326 and the sliding groove 404, the rotating assembly 50 can also be in other forms, for example, the second hinge part 32 is provided with an elastic part, and the sliding piece is provided with a limiting hole, when the second hinge part 32 rotates relative to the sliding piece 40, the elastic part slides at the bottom of the sliding piece until the elastic part is limited in the limiting hole.

[0122] In the embodiment, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α1, that is, when the second hinge part 32 moves together with the sliding piece 40 relative to the first hinge part 31, the door body 20 includes multiple movement trajectories.

[0123] In combination Figure 13 In the first movement trajectory, the first shaft body 311 rotates in place in the first groove body 401 as the first rotation axis P1, and the second shaft body 312 moves in the second groove body 402 with the first rotation axis P1 as the central axis.

[0124] That is, in the entire opening process of the door body 20, the movement trajectory of the door body 20 is that the door body 20 first rotates in place with the first rotation axis P1 as the central axis, and then the door body 20 switches to continue to rotate in place with the second rotation axis P2 as the central axis.

[0125] It should be noted that in the first movement trajectory, the second shaft body 312 and the second groove body 402 can be omitted, and only the first shaft body 311 rotates in place in the first groove body 401 to drive the door body 20 to rotate in place with the first rotation axis P1 as the central axis.

[0126] In combination Figure 14 In the second movement trajectory, the first groove body 401 and the second groove body 402 are both in a strip shape, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α1, the second shaft body 312 moves in the second groove body 402 to drive the first shaft body 311 to move in the first groove body 401, and the door body 20 generates a translation amount relative to the cabinet 10.

[0127] Here, the "translation amount of the door body 20 relative to the cabinet 10" means that in the process of the door body 20 rotating relative to the cabinet 10, there is also a translation amount, when corresponding to a refrigerator, the translation amount refers to a horizontal movement amount, that is, in addition to the door body 20 rotating relative to the cabinet 10, the door body 20 also generates a horizontal movement amount relative to the cabinet 10.

[0128] That is, during the whole opening process of the door body 20, the movement track of the door body 20 is that the door body 20 rotates and translates with the first rotation axis P1 as the center axis, and then the door body 20 switches to continue rotating in place with the second rotation axis P2 as the center axis.

[0129] Next, various specific examples of the translation of the door body 20 are introduced.

[0130] In the first specific example, in combination with Figure 14 , the cabinet 10 includes a containing chamber D and a pivot side P connected with the hinge assembly, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α1, the door body 20 moves from the pivot side P to the containing chamber D.

[0131] Specifically, the first groove body 401 includes an initial position A1 and a first stop position A2, when the hinge assembly 30 is in the closed state, the first shaft body 311 is located at the initial position A1, and the second shaft body 312 is located at one end of the second groove body 402, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α1, the second shaft body 312 moves in the second groove body 402 to drive the first shaft body 311 to move from the initial position A1 to the first stop position A2, and the door body 20 moves from the pivot side P to the containing chamber D.

[0132] That is, the door body 20 moves a certain distance away from the cabinet 200, so as to avoid mutual interference between the door body 20 and the cabinet 200 in the preliminary opening process.

[0133] Here, the door body 20 includes a front wall 21 away from the containing chamber D and a side wall 22 always clamped between the front wall 21 and the containing chamber D, and the initial position A1 is farther away from the front wall 21 and the side wall 22 than the first stop position A2.

[0134] In the second specific example, in combination with Figure 15 , the first groove body 401 includes an initial position A1 and a first stop position A2, and the second groove body 402 includes a first section L1 and a second section L2 connected with each other, when the hinge assembly 30 is in the process of being opened from the closed state to the first intermediate opening angle α11, the first shaft body 311 remains at the initial position A1, and the second shaft body 312 moves in the first section L1 with the first shaft body 311 as the center axis, when the hinge assembly 30 is in the process of being opened from the first intermediate opening angle α11 to the first opening angle α1, the second shaft body 312 moves in the second section L2 to drive the first shaft body 311 to move from the initial position A1 to the first stop position A2, and the door body 20 moves from the pivot side P to the containing chamber D.

[0135] That is, the door body 20 first rotates a certain angle in place, and then moves a certain distance away from the cabinet 200, so as to avoid mutual interference between the door body 20 and the cabinet 200 in the initial opening process.

[0136] Here, in the side-by-side left and right doors of the side-by-side door refrigerator or the multi-door refrigerator with vertical beams, the door body 20 first rotates a certain angle in place to avoid mutual interference between the left and right doors.

[0137] In a third specific example, in combination with Figure 16 , the first slot body 401 includes a first stop position A2, a second stop position A3, and an initial position A1 located between the first stop position A2 and the second stop position A3, and the second slot body 402 includes a first section L1, a second section L2, and a third section L3 connected in sequence. When the hinge assembly 30 is in the process of opening from the closed state to the first intermediate opening angle a11, the first shaft body 311 is kept in the initial position A1, and the second shaft body 312 moves in the first section L1 with the first shaft body 311 as the center axis. When the hinge assembly 30 is in the process of continuing to open from the first intermediate opening angle a11 to the second intermediate opening angle a12, the second shaft body 312 moves in the second section L2 to drive the first shaft body 311 to move from the initial position A1 to the first stop position A2, and the door body 20 moves from the pivot side P to the containing chamber D. When the hinge assembly 30 is in the process of continuing to open from the second intermediate opening angle a12 to the first opening angle a1, the second shaft body 312 moves in the third section L3 to drive the first shaft body 311 to move from the first stop position A2 to the second stop position A3, and the door body 20 moves from the containing chamber D to the pivot side P.

[0138] Here, when the door body 20 moves from the containing chamber D to the pivot side P, the opening degree of the cabinet 10 can be increased as much as possible under the premise of avoiding mutual interference between the door body 20 and the cabinet 200, so as to avoid the door body 20 from hindering the normal pulling of the drawer, the shelf, and other components in the cabinet 10.

[0139] It should be noted that the initial position A1, the first stop position A2, and the second stop position A3 are located on the same straight line, and the initial position A1 is a position between the first stop position A2 and the second stop position A3, that is, there is a gap between the initial position A1 and the first stop position A2 and the third stop position A3, but it is not limited thereto. The initial position A1 can coincide with the second stop position A3, or the initial position A1, the first stop position A2, and the second stop position A3 can also be located on different straight lines.

[0140] In other embodiments, in combination with Figure 17 and Figure 18When the first hinge part 3 is in the first position, the limiting groove 321 is coincided with the first groove body 401, the first shaft body 311 extends to the coincided limiting groove 321 and the first groove body 401, and the second shaft body 312 extends to the second groove body 402, and the second shaft body 312 is spaced apart from the second hinge part 32.

[0141] That is, the other embodiments are different from the foregoing embodiments in that the limiting groove 321 in the other embodiments is overlapped with the first groove body 401, while the limiting groove 322 in the foregoing embodiments is overlapped with the second groove body 402.

[0142] The other descriptions of the hinge assembly 30 can refer to the foregoing embodiments, and will not be described here again.

[0143] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, for example, the technologies in different embodiments can be used together to achieve the corresponding effects, and the solutions are within the protection scope of the present application. It should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
