Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a hinge assembly with a protrusion and a refrigeration device having the same. Background Art

[0002] Many devices have an openable door installed in their housings. Typically, the door is rotatably mounted relative to the housing. To achieve this, a single-axis hinge is typically used. The door rotates around the hinge's fixed axis in a circular motion, thereby opening or closing the door. Because the fixed axis around which the door rotates remains stationary, the door easily extends beyond the side of the device during opening. This hinge significantly limits the door's opening angle when the gap between the device and the wall is small, making it inconvenient to use. Through continuous research and development, technicians have also invented embedded hinges, but these are complex, occupy a large space, and are inconvenient to install. Summary of the Invention

[0072] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0073] In the various drawings of the present invention, for the sake of convenience, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, only the basic structure of the subject matter of the present invention is illustrated.

[0074] Ginseng Figure 1 , which is a schematic diagram of a refrigeration device 100 according to an embodiment of the present invention.

[0075] The refrigeration device 100 includes a cabinet 10 , a door 20 , and a hinge assembly 30 connecting the cabinet 10 and the door 20 .

[0076] It should be noted that the refrigeration device 100 may be a refrigerator, a freezer, a wine cabinet, etc. Here, the refrigeration device 100 is taken as an example of a refrigerator.

[0077] In addition, the hinge assembly 30 is not only applicable to the refrigeration device 100, but also applicable to other scenarios, such as cabinets, wardrobes, etc. The present invention uses the hinge assembly 30 applied to the refrigerator 100 as an example for illustration, but is not limited to this.

[0078] Combine Figures 2 to 4 , is a schematic diagram of a hinge assembly 30 with a protrusion according to an embodiment of the present invention.

[0079] The hinge assembly 30 includes a first hinge member 31 connected to the box body 10 , a second hinge member 32 connected to the door body 20 , and a sliding piece 40 connecting the first hinge member 31 and the second hinge member 32 .

[0080] Here, “the first hinge 31 connected to the box body 10 ” means that the first hinge 31 is connected to the box body 10 . The first hinge 31 may be an independent component mounted to the box body 10 , or may be a component directly integrally formed on the box body 10 .

[0081] Similarly, “the second hinge member 32 connected to the door body 20 ” means that the second hinge member 32 is connected to the door body 20 . The second hinge member 32 may be an independent component mounted to the door body 20 , or may be a component directly integrally formed on the door body 20 .

[0082] The hinge assembly 30 further includes a first shaft 311 and a second shaft 312 located on the first hinge member 31, a first groove 401 and a second groove 402 located on the slide 40, a first protrusion 321 and a second protrusion 322 located on the second hinge member 32, and a rotating assembly 50 located between the slide 40 and the second hinge member 32.

[0083] Here, "the first axis 311 and the second axis 312 located on the first hinge part 31" means that the first axis 311 and the second axis 312 are arranged on the first hinge part 31, and the first axis 311 and the second axis 312 can be integrally formed with the first hinge part 31, or can be assembled into one body with each other. The explanation of "located" in other parts of the present invention can be referred to the description here and will not be repeated later.

[0084] The first shaft body 311 includes a first slide groove 313, the first shaft body 311 passes through the first groove body 401 and extends to the second hinge part 32, the first protrusion 321 is limited in the first slide groove 313, the second shaft body 312 includes a second slide groove 314, the second shaft body 312 passes through the second groove body 402 and extends to the second hinge part 32, and the second protrusion 322 is limited in the second slide groove 314.

[0085] Here, the first protrusion 321 is a long strip structure, and the first protrusion 321 can slide in the first sliding groove 313 to drive the second hinge component 32 and the first shaft body 311 to move relative to each other. Similarly, the second protrusion 322 is a long strip structure, and the second protrusion 322 can slide in the second sliding groove 314 to drive the second hinge component 32 and the second shaft body 312 to move relative to each other.

[0086] When the hinge assembly 30 is in the opening process, the first shaft 311 moves relative to the first groove 401 and the first protrusion 321, and the second shaft 312 moves relative to the second groove 402 and the second protrusion 322, thereby driving the second hinge part 32 and the slide 40 to move relative to the first hinge part 31 until the first shaft 311 is limited to the first groove 401 and / or the second shaft 312 is limited to the second groove 402, and then the rotating assembly 50 drives the second hinge part 32 to move relative to the slide 40.

[0087] Here, the extension direction of the first protrusion 321 is consistent with the extension direction of the first groove body 401, that is, the extension direction of the first protrusion 321 is roughly the extension direction of the center line of the first groove body 401. When the hinge assembly 30 is in a closed state, in the overlapping direction of the first hinge part 31, the slide 40 and the second hinge part 32, the first protrusion 321 roughly coincides with the center line of the first groove body 401. In this way, when the first shaft body 311 slides in the first groove body 401, the first shaft body 311 can slide relative to the first protrusion 321 at the same time, and during the sliding process, no relative movement will be generated between the first protrusion 321 and the first groove body 401, so that the second hinge part 32 and the slide 40 can remain relatively stationary.

[0088] Similarly, the extension direction of the second protrusion 322 is consistent with the extension direction of the second groove body 402. Other descriptions of the second protrusion 322, the second groove body 402, and the second shaft body 312 can refer to the description of the first protrusion 321, the first groove body 401, and the first shaft body 311 above, and will not be repeated here.

[0089] It can be seen that the first shaft 311 is simultaneously limited to the first groove 401 and the first protrusion 321, and the second shaft 312 is simultaneously limited to the second groove 402 and the second protrusion 322. In this way, when the first shaft 311 moves in the first groove 401 and the second shaft 312 moves in the second groove 402, the second hinge 32 and the slide 40 can remain relatively stationary, and the second hinge 32 and the slide 40 can be controlled to move relative to the first hinge 31.

[0090] It should be noted that "the hinge assembly 30 is in the opening process" means that the second hinge member 32 opens in a direction away from the first hinge member 31, that is, the second hinge member 32 is acted in one direction to drive the second hinge member 32 to move in a direction away from the first hinge member 31. 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.

[0091] In this embodiment, the second hinge member 32 first moves with the slide 40 relative to the first hinge member 31, and then the rotating assembly 50 drives the second hinge member 32 to move relative to the slide 40. It can be seen that during the entire opening process of the hinge assembly 30, two movements are realized. The two movement processes can realize the change of the position of the rotation axis, 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, especially in the field of built-in refrigerators. The switching of the rotation axis can avoid the door body 20 from interfering with the surrounding cabinets or walls during the opening and closing process.

[0092] That is to say, this embodiment can control the locking and unlocking between the first hinge part 31, the second hinge part 32 and the slide 40 through the structure of the hinge assembly 30. Specifically, the second hinge part 32 and the slide 40 are first controlled to be locked with each other, and then the second hinge part 32 and the slide 40 are controlled to move relative to the first hinge part 31, and then the second hinge part 32 and the slide 40 are controlled to be unlocked and the first hinge part 31 and the slide 40 are locked with each other, and then the second hinge part 32 is controlled to move relative to the slide 40.

[0093] Specifically, in this embodiment, when the hinge assembly 30 is in the process of opening from a closed state to a first opening angle α1, the second hinge member 32 and the slide 40 rotate relative to the first hinge member 31 with the first rotation axis 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 member 32 rotates relative to the slide 40 with the second rotation axis P2 as the center axis.

[0094] Here, the first rotation axis P1 may be a virtual axis or a physical axis.

[0095] The virtual axis refers to an axis that does not actually exist in the hinge assembly 30 , and the physical axis refers to a component actually included in the hinge assembly 30 .

[0096] In addition, the first rotation axis P1 can be a non-fixed axis or a fixed axis.

[0097] A non-fixed axis means that the position of the first rotating axis P1 is always in a changing process, that is, the relative position between the first rotating axis P1 and the box body 10 or the door body 20 is changing, while a fixed axis means that the position of the first rotating axis P1 is fixed, that is, the relative position between the first rotating axis P1 and the box body 10 or the door body 20 is fixed.

[0098] Similarly, the second rotation axis P2 can be a virtual axis or a physical axis, and can be a non-fixed axis or a fixed axis. The second rotation axis P2 is staggered with the first rotation axis P1, that is, the position of the second rotation axis P2 is inconsistent with the position of the first rotation axis P1.

[0099] It can be seen that the hinge assembly 30 of this embodiment can effectively control the order of the two rotations. There is a change in the position of the rotation axis during the two rotations, which can effectively control the movement trajectory of the door body 20, thereby improving the degree of freedom of the opening and closing process of the door body 20 of the refrigerator 100, especially in the field of built-in refrigerators. By switching the rotation axis, the door body 20 can be prevented from interfering with the surrounding cabinets or walls during the opening and closing process.

[0100] In order to further illustrate the motion trajectory of the hinge assembly 30, Figure 5, a simple schematic diagram in which the hinge assembly 30 is assembled to the refrigerator 100 and the refrigerator 100 is embedded in the cabinet 200 is used as an example for explanation.

[0101] The box body 10 includes an opening 102 and a front end surface 103 arranged around the opening 102. The box body 10 also includes a accommodating chamber D and an outer side surface 13 adjacent to the hinge assembly 30 and on an extension section of the rotation path of the door body 20. The door body 20 includes a front wall 21 away from the accommodating chamber D and a side wall 22 always sandwiched between the front wall 21 and the accommodating chamber D. There is a side edge 23 between the front wall 21 and the side wall 22.

[0102] The hinge assembly 30 is configured as follows: when the first rotating axis P1 is actuated, there is a first distance between the first rotating axis P1 and the front end surface 103 of the box body 10; when the second rotating axis P2 is actuated, there is a second distance between the second rotating axis P2 and the front end surface 103 of the box body 10, and the second distance is greater than the first distance.

[0103] In addition, when the first rotating axis P1 is actuated, a third distance is formed between the first rotating axis P1 and the outer side surface 13 of the box body 10. When the second rotating axis P2 is actuated, a fourth distance is formed between the second rotating axis P2 and the outer side surface 13 of the box body 10. The fourth distance is smaller than the third distance.

[0104] Here, "the first rotating axis P1 is actuated" means that the first rotating axis P1 is in a working state, that is, at this time the second hinge member 32 and the slide 40 rotate relative to the first hinge member 31. Similarly, "the second rotating axis P2 is actuated" means that the second rotating axis P2 is in a working state, that is, at this time the second hinge member 32 rotates relative to the slide 40.

[0105] 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 surface 103 and the outer surface 13 of the box body 10 when the hinge assembly 30 moves to a certain position, rather than the distance in the closed state.

[0106] The specific instructions are as follows:

[0107] In actual operation, in order to improve the embedding effect, it is better to make the refrigerator 100 completely embedded in the cabinet 200. The refrigerator 100 is a free embedded refrigerator, that is, the front end 201 of the cabinet 200 and the front wall 21 of the door body 20 away from the box body 10 are in the same plane, or the front wall 21 of the door body 20 does not protrude from the front end 201 of the cabinet 200 at all.

[0108] In the prior art, refrigerators are all single-axis refrigerators, and a certain distance needs to be maintained between the rotating axis of the refrigerator and the side walls and front walls of the refrigerator, so that there is enough space to meet the needs of foaming or other processes. That is, the rotating axis position of the existing refrigerator is approximately Figure 5In this case, after the single-axis refrigerator is embedded into the cabinet 200, since the corner 203 of the cabinet 200 between the front end 201 and the inner wall 202 corresponds to the side edge 23 of the door body 20, when the door body 20 is opened, the side edge 23 will interfere with the door body 20 and limit the maximum opening angle of the door body 20. In order to ensure the normal opening of the door body 20, the usual practice in the prior art is to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100. The distance needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

[0109] Combine 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 P3 as the central axis (i.e., the prior art), refer to Figure 5 In the dotted door body 20', since the uniaxial shaft P3 is close to the front end surface 103, that is, the uniaxial shaft P3 is away from the front end 201 of the cabinet 200 at this time, when the door body 20' is opened to a certain angle, the corners 203 of the cabinet 200 will interfere with the door body 20' and limit the maximum opening angle of the door body 20'.

[0110] In the present embodiment, the door body 20 first rotates with the first rotation axis P1 as the central axis, specifically, the second hinge 32 and the slide 40 rotate together with respect to the first hinge 31 by a certain angle. As the positions of the second hinge 32 and the slide 40 change, the relative position of the second rotation axis P2 and the box body 10 also changes, and the second rotation axis P2 gradually moves away from the front end surface 103, that is, the second rotation axis P2 gradually moves toward the direction of the front end 201 of the cabinet 200. At this time, the door body 20 rotates again with the second rotation axis P2 at the current position as the central axis. Since the second rotation axis P2 at this time is farther away from the front end surface 103 of the box body 10 than the first rotation axis P1, refer to Figure 5 In the solid line door body 20, the interference effect of the corners 203 of the cabinet 200 on the door body 20 is greatly reduced. Only when the door body 20 is opened to a larger angle will the corners 203 of the cabinet 200 interfere with each other, thereby greatly improving the maximum opening angle of the door body 20.

[0111] That is to say, in this embodiment, after the door body 20 is opened to a certain angle, it switches to rotation with the second rotation axis P2 as the central axis. Under the premise of ensuring that the refrigerator 100 is freely embedded in the cabinet 200, the maximum opening angle of the door body 20 can be effectively increased, thereby facilitating the user to operate the refrigerator 100 and greatly improving the user experience.

[0112] Moreover, this embodiment does not need to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, and can achieve a seamless connection between the refrigerator 100 and the cabinet 200, greatly improving the embedding effect.

[0113] In addition, the second rotating axis P2 of the present embodiment gradually moves toward the direction approaching the front end 201 of the cabinet 200, and also gradually moves toward the inner wall 202 of the cabinet 200. That is to say, when the door body 20 rotates with the second rotating axis P2 as the center axis, the second rotating axis P2 at this time is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first rotating axis P1. In this way, the maximum opening angle of the door body 20 can be increased, and the door body 20 can be moved away from the box body 10 to increase the opening degree of the box body 10, so as to facilitate the opening and closing of shelves, drawers, etc. in the box body 10, or to facilitate the taking and placing of items.

[0114] Of course, the second rotation axis P2 which ultimately serves as the central axis may also be located at other positions. For example, when the door body 20 rotates with the second rotation axis P2 as the rotation axis, the second rotation axis P2 is closer to the front end 201 of the cabinet 200 than the first rotation axis P1, and the second rotation axis P2 is farther away from the inner wall 202 of the cabinet 200 than the first rotation axis P1, and so on.

[0115] It is understandable that the slide 40 controls the switching sequence of the first hinge 31 and the second hinge 32 during the opening and closing process of the door body 20, which can effectively avoid the door body 20 from interfering with the cabinet 200 during the opening and closing process.

[0116] In this embodiment, combined with Figures 2 to 5 The first shaft body 311 includes two first protrusions 3111 , and the two first protrusions 3111 cooperate to form a first sliding groove 313 . The second shaft body 312 includes two second protrusions 3121 , and the two second protrusions 3121 cooperate to form a second sliding groove 314 .

[0117] Here, the first protrusion 3111 and the second protrusion 3121 are both cylindrical protrusions.

[0118] In this way, when the first slide groove 313 moves relative to the first protrusion 321, the two first protrusions 3111 are actually located on both sides of the first protrusion 321 and slide relative to the first protrusion 321, which can reduce the friction between the first slide groove 313 and the first protrusion 321, and avoid the first slide groove 313 and the first protrusion 321 from getting stuck during the sliding process and being unable to continue relative movement.

[0119] Similarly, when the second slide groove 314 moves relative to the second protrusion 322, the two second protrusions 3121 are actually located on both sides of the second protrusion 322 and slide relative to the second protrusion 322, which can reduce the friction between the second slide groove 314 and the second protrusion 322, and avoid the second slide groove 314 and the second protrusion 322 from getting stuck and unable to continue relative movement during the sliding process.

[0120] In this embodiment, the first shaft 311 also includes a first shaft body 3112 connected to the first hinge part 31, and the second shaft 312 also includes a second shaft body 3122 connected to the first hinge part 31. The two first protrusions 3111 are located on the side of the first shaft body 3112 away from the first hinge part 31, and the two second protrusions 3121 are located on the side of the second shaft body 3122 away from the first hinge part 31.

[0121] Here, the first shaft body 3112 cooperates with the first slot body 401 , and the diameter of the first shaft body 3112 matches the opening width of the first slot body 401 , thereby preventing the first shaft body 311 and the first slot body 401 from shaking with each other.

[0122] Likewise, the second shaft body 3122 cooperates with the second slot body 402 , and the diameter of the second shaft body 3122 matches the opening width of the second slot body 402 , thereby preventing the second shaft body 312 and the second slot body 402 from shaking with each other.

[0123] Of course, in other embodiments, Figure 6 , the two first bosses 3111 and the two second bosses 3121 can be directly connected to the first hinge member 31.

[0124] In this embodiment, the hinge assembly 30 also includes a first extension portion 323 connected to the first protrusion 321 and a second extension portion 324 connected to the second protrusion 322. When the second hinge member 32 moves relative to the slide 40, the first sliding groove 313 slides relative to the first extension portion 323, and the second sliding groove 314 slides relative to the second extension portion 324.

[0125] The first extending portion 323 and the second extending portion 324 are both arc-shaped protrusions, and the central axis of the arc-shaped protrusions is the second rotation axis P2 .

[0126] Here, the second hinge member 32 and the slide 40 are actually matched through two parts, one part is the connection of the rotating assembly 50, and the other part is the first groove body 401 and the first protrusion 321 that cooperate with each other, and the second groove body 402 and the second protrusion 322 that cooperate with each other. Among them, since the central axis when the first shaft body 311 rotates relative to the first protrusion 321 and the second shaft body 312 rotates relative to the second protrusion 322 is the first rotation axis P1, and the central axis when the rotating assembly 50 rotates is the second rotation axis P2, the second hinge member 32 cannot rotate at the same time with the first rotation axis P1 and the second rotation axis P2 that are inconsistent in position, that is, when the first shaft body 311 slides at the first protrusion 321 (or the second shaft body 312 slides at the second protrusion 322), the rotating assembly 50 cannot drive the second hinge member 32 to rotate relative to the slide 40, that is, the second hinge member 32 and the slide 40 are relatively stationary at this time.

[0127] Specifically, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the first shaft 311 passes through the first sliding groove 313 and is restrained by the first protrusion 321 (or the second shaft 312 passes through the second sliding groove 314 and is restrained by the second protrusion 322). Due to the restraining effect of the first shaft 311 on the first protrusion 321, the second hinge member 32 cannot rotate relative to the slide 40 about the second rotation axis P2 as the central axis, that is, the second hinge member 32 and the slide 40 are relatively stationary. At this time, Through the movement of the first shaft 311 in the first groove 401 and the first protrusion 321 (or the movement of the second shaft 312 in the second groove 402 and the second protrusion 322), the second hinge 32 and the slide 40 can rotate together relative to the first hinge 31 until the first shaft 311 is limited to the first groove 401 and / or the second shaft 312 is limited to the second groove 402. At this time, the slide 40 can no longer continue to rotate relative to the first hinge 31, and the first hinge 31 and the slide 40 are locked with each other.

[0128] 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 also has a first extension portion 323 connected to the first protrusion 321 and a second extension portion 324 connected to the second protrusion 322, the first shaft 311 moves at the first extension portion 323 with the second rotation axis P2 as the center axis, and the second shaft 312 moves at the second extension portion 324 with the second rotation axis P2 as the center axis, the second hinge component 32 can be driven to rotate relative to the slide 40.

[0129] It is understandable that, in other embodiments, other structures may be added to ensure that the second hinge 32 and the slide 40 remain relatively stationary during the process of opening from the closed state to the first opening angle α1.

[0130] In this embodiment, the second rotation axis P2 is a fixed axis, and the second hinge 32 rotates in place relative to the sliding plate 40 around the second rotation axis P2 as a central axis.

[0131] The second rotation axis P2 can be a virtual axis or a physical axis, depending on actual conditions.

[0132] In this embodiment, continue to combine Figures 2 to 5 The rotating assembly 50 includes a third shaft 403 and a circular hole 325 located between the sliding piece 40 and the second hinge member 32 . The third shaft 403 rotates in the circular hole 325 as the second rotating axis P2 .

[0133] Here, the second rotation axis P2 is a physical axis, the third shaft 403 is located on the side of the slide 40 close to the second hinge part 32, and the circular hole 325 is located in the second hinge part 32. When the second hinge part 32 rotates relative to the slide 40, the third shaft 403 rotates in place in the circular hole 325, the first shaft 311 slides at the first extension part 323, and the second shaft 312 slides at the second extension part 324.

[0134] In addition, the rotating assembly 50 further includes a protrusion 326 and a sliding groove 404 located between the sliding plate 40 and the second hinge 32 . The protrusion 326 slides in the sliding groove 404 with the second rotating axis P2 as the center axis.

[0135] At this time, when the second hinge 32 rotates relative to the slide 40, the third shaft 403 rotates in place in the circular hole 325, and the protrusion 326 slides in the sliding groove 404 with the second rotation axis P2 as the center axis. In this way, the stability of the second hinge 32 rotating relative to the slide 40 can be improved.

[0136] In addition, when the protrusion 326 slides in the slide groove 404 to the end of the slide groove 404 (that is, when the protrusion 326 slides to the extreme position), the first hinge member 32 can no longer rotate relative to the slide 40, and the maximum opening angle of the door body 20 can be controlled by the length of the slide groove 404, but it is not limited to this.

[0137] In other embodiments, the rotating assembly 50 may not include the third shaft 403 and the circular hole 325 , that is, the second rotating axis P2 is a virtual axis.

[0138] That is to say, the rotating component 50 may only include the third shaft 403 and the circular hole 325, but not the protrusion 326 and the slide groove 404. In this case, the second rotating axis P2 is a physical axis. Alternatively, the rotating component 50 may only include the protrusion 326 and the slide groove 404, but not the third shaft 403 and the circular hole 325. In this case, the second rotating axis P2 is a virtual axis. Alternatively, the rotating component 50 includes the protrusion 326, the slide groove 404, the third shaft 403 and the circular hole 325 at the same time. In this case, the second rotating axis P2 is a physical axis.

[0139] In this embodiment, the protrusion 326 is located on the second hinge member 32 , the protrusion 326 is a ridge 326 , the sliding groove 404 is located on the sliding sheet 40 , and the sliding groove 404 passes through the first slot body 401 and / or the second slot body 402 .

[0140] Here, the ridge 326 is an arc-shaped ridge with a certain length, and the slide groove 404 is an arc groove with the second rotation axis P2 as the center axis. "The slide groove 404 passes through the first groove body 401 and / or the second groove body 402" means that the extension trajectory of the slide groove 404 is connected to the first groove body 401 and / or the second groove body 402, and the ridge 326 can slide in the slide groove 404 and enter the first groove body 401 and / or the second groove body 402.

[0141] When the slide groove 404 passes through the first groove body 401, the ridge 326 moves in the slide groove 404 and passes through the first groove body 401. The ridge 326 cooperates with the first groove body 401 to limit the first shaft body 311. Specifically, the ridge 326 cooperates with the end of the first groove body 401 to limit the first shaft body 311. The ridge 326 is tangent to the outer contour of the first shaft body 311.

[0142] In other embodiments, the slide groove 404 may also be directly located on the first shaft 311 and / or the second shaft 312 , and the first shaft 311 and / or the second shaft 312 may be directly limited by the cooperation between the ridge 326 and the slide groove 404 .

[0143] It is understandable that when the door body 20 is closed from the maximum opening angle, if the first shaft 311 and the second shaft 312 are not limited at this time, the first shaft 311 may move back in the first groove 401 and the second shaft 312 may move back in the second groove 402, that is, the reset movement of the slide 40 may be earlier than the reset movement of the second hinge 32. In this way, there is a risk that the movement trajectory of the door body 20 when closing is uncontrolled.

[0144] When the door 20 is closed by the maximum opening angle, the slide 40 can rotate only when the first and second shaft bodies 311 and 312 are separated from the limiting position of the rib 326. That is to say, when the door 20 is closed by the maximum opening angle, the second hinge member 32 is first driven to reset by the movement of the rib 326 in the slide groove 404 until the rib 326 is separated from the first groove body 401 and / or the second groove body 402, and the first protrusion 321 is reset with the first groove body 401, and the second protrusion 322 is reset with the second groove body 402, and then the second hinge member 32 and the slide 40 are driven to reset together by the movement of the first shaft body 311 in the first groove body 401 and the first protrusion 321, and the movement of the second shaft body 312 in the second groove body 402 and the second protrusion 322.

[0145] In this embodiment, combined with Figure 7The rib 326 is located on one side surface of the second hinge member 32 close to the slide 40. The slide groove 404 only passes through the second groove body 402, and the slide groove 404 extends to both sides of the second groove body 402. The rib 326 moves in the slide groove 404 and passes through the second groove body 402. The rib 326 cooperates with the end of the second groove body 402 to limit the second shaft body 312, that is, a part of the second shaft body 312 abuts the end of the second groove body 402, and the other part of the second shaft body 312 is tangent to the rib 326.

[0146] It should be noted that, when the rib 326 slides to the end of the sliding groove 404 , a portion of the rib 326 is still located in the second groove 402 to limit the second shaft 312 .

[0147] In other embodiments, the ridge 326 may only pass through the first slot 401 to limit the position of the first shaft 311 .

[0148] Alternatively, the rib 326 passes through the first groove body 401 and the second groove body 402 at the same time to limit the first shaft body 311 and the second shaft body 312 at the same time. In this case, the rib 326 can be two separately arranged ribs.

[0149] Alternatively, the protruding rib 326 directly passes through the first shaft 311 .

[0150] Specific, combined Figure 8 A limiting column 3113 is further provided on the side of the first shaft body 3112 away from the first hinge member 31. The limiting column 3113 cooperates with the first protruding column 3111 to form a gap, and the ridge 326 can pass through the gap (that is, the ridge 326 passes through the first shaft body 311) to limit the first shaft body 311.

[0151] Alternatively, the protruding rib 326 simply passes through the second shaft 312 .

[0152] Alternatively, the rib 326 directly passes through the first shaft 311 and the second shaft 312 at the same time.

[0153] Alternatively, the sliding groove 404 only passes through the first groove body 401 , and the ridge 326 passes through both the sliding groove 404 and the first shaft body 311 .

[0154] Alternatively, the sliding groove 404 only passes through the second groove body 402 , and the ridge 326 passes through both the sliding groove 404 and the second shaft body 312 .

[0155] Alternatively, the sliding groove 404 passes through the first groove body 401 and the second groove body 402 at the same time, and the ridge 326 passes through the sliding groove 404, the first shaft body 311 and the second shaft body 312 at the same time.

[0156] In other embodiments, the protrusion 326 and the sliding groove 404 may have other structures.

[0157] For example, combined with Figure 9 The protrusion 326 is located on the second hinge member 32 , the protrusion 326 is a boss 326 , the slide groove 404 is located on the slide 40 , the slide groove 404 and the first slot body 401 are staggered with each other, and the slide groove 404 and the second slot body 402 are staggered with each other.

[0158] At this time, when the second hinge 32 rotates relative to the slide 40 , the boss 326 slides in the slot 404 until the boss 326 abuts against the end of the slot 404 . The slot 404 and the boss 326 can be interchanged.

[0159] Of course, in addition to the protrusion 326 and the slide groove 404, the rotating component 50 can also be in other forms. For example, the second hinge component 32 is provided with an elastic component, and the slide is provided with a limiting hole. When the second hinge component 32 rotates relative to the slide 40, the elastic component slides at the bottom of the slide until the elastic component is limited in the limiting hole.

[0160] In this embodiment, when the hinge assembly 30 is in the process of opening from a closed state to the first opening angle α1, that is, when the second hinge member 32 and the slide 40 move relative to the first hinge member 31, the door body 20 includes multiple movement trajectories.

[0161] Combine Figure 10 In the first motion trajectory, the first shaft 311 rotates in place in the first slot 401 as the first rotation axis P1, and the second shaft 312 moves in the second slot 402 with the first rotation axis P1 as the center axis.

[0162] That is to say, during the entire opening process of the door body 20, the movement trajectory of the door body 20 is: the door body 20 first rotates in place 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.

[0163] It should be noted that in the first motion trajectory, the second shaft 312 and the second groove 402 can be omitted, and only the first shaft 311 rotates in situ in the first groove 401 to drive the door body 20 to rotate in situ around the first rotation axis P1 as the center axis.

[0164] Combine Figure 11 In the second motion trajectory, the first slot body 401 and the second slot body 402 are both long strips. When the hinge assembly 30 is in the process of opening from a closed state to the first opening angle α1, the second shaft body 312 moves in the second slot body 402 and drives the first shaft body 311 to move in the first slot body 401, and the door body 20 produces a translational displacement relative to the box body 10.

[0165] Here, "the door body 20 produces a translational amount relative to the cabinet 10" means that the door body 20 also produces a translational amount during the process of rotating relative to the cabinet 10. When corresponding to the refrigerator, the translational amount refers to the horizontal movement amount, that is, in addition to rotating relative to the cabinet 10, the door body 20 also produces a horizontal movement relative to the cabinet 10.

[0166] That is to say, during the entire opening process of the door body 20, the movement trajectory of the door body 20 is: the door body 20 first rotates and translates around the first rotation axis P1 as the center axis, and then the door body 20 switches to continue rotating in place around the second rotation axis P2 as the center axis.

[0167] Below, various specific examples of the translation of the door body 20 are introduced.

[0168] In the first specific example, combined with Figure 11 The box 10 includes a receiving chamber D and a pivot side P (combined with a hinge assembly) Figure 1 and Figure 5 ), when the hinge assembly 30 is in the process of opening from a closed state to a first opening angle α1, the door body 20 moves from the pivot side P toward the accommodating chamber D.

[0169] Specifically, the first slot body 401 includes an initial position A1 and a first stop position A2. When the hinge assembly 30 is in a 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 slot body 402. When the hinge assembly 30 is in the process of opening from a closed state to a first opening angle α1, the second shaft body 312 moves in the second slot body 402 and drives 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 toward the accommodating chamber D.

[0170] That is, the door body 20 moves a certain distance away from the cabinet 200 to avoid interference between the door body 20 and the cabinet 200 during the initial opening process.

[0171] Here, the door body 20 includes a front wall 21 away from the accommodating chamber D and a side wall 22 always sandwiched between the front wall 21 and the accommodating chamber D. The initial position A1 is farther from the front wall 21 and the side wall 22 than the first stop position A2.

[0172] In the second specific example, combined with Figure 12The first slot body 401 includes an initial position A1 and a first stop position A2, and the second slot body 402 includes a connected first section L1 and a second section L2. When the hinge assembly 30 is in the process of opening from a closed state to a first intermediate opening angle α11, the first shaft body 311 remains 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 α11 to the first opening angle α1, the second shaft body 312 moves in the second section L2 and drives 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 toward the accommodating chamber D.

[0173] 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 interference between the door body 20 and the cabinet 200 during the initial opening process.

[0174] Here, in a double-door refrigerator or a multi-door refrigerator with vertical beams, there are a left door and a right door arranged side by side. The door body 20 is first rotated in place by a certain angle to avoid interference between the left door and the right door.

[0175] In the third specific example, combined with Figure 13 The first slot 401 includes a first stop position A2, a second stop position A3 and an initial position A1 between the first stop position A2 and the second stop position A3. The second slot 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 α11, the first shaft 311 remains in the initial position A1, and the second shaft 312 moves in the first section L1 with the first shaft 311 as the central axis. When the hinge assembly 30 is in the process of opening from the first intermediate opening angle When α11 continues to open to the second intermediate opening angle α12, the second shaft 312 moves in the second section L2 and drives the first shaft 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 toward the accommodating chamber D. When the hinge assembly 30 is in the process of continuing to open from the second intermediate opening angle α12 to the first opening angle α1, the second shaft 312 moves in the third section L3 and drives the first shaft 311 to move from the first stop position A2 to the second stop position A3, and the door body 20 moves from the accommodating chamber D toward the pivot side P.

[0176] Here, when the door body 20 moves from the accommodating chamber D toward the pivot side P, the opening of the box body 10 can be increased as much as possible while avoiding interference between the door body 20 and the cabinet 200, so as to prevent the door body 20 from hindering the normal pulling and pulling of drawers, shelves and other components in the box body 10.

[0177] 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 the 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 this is not limited to it. The initial position A1 may coincide with the second stop position A3, or the initial position A1, the first stop position A2 and the second stop position A3 may also be located on different straight lines.

[0178] Next, the specific working process of the hinge assembly 30 of the first embodiment is introduced.

[0179] Combine Figures 14 to 18 When the hinge assembly 30 is in a closed state, the first shaft 311 extends to the first groove 401 and the first protrusion 321, and the first shaft 311 is located at the initial position A1 of the first groove 401. The second shaft 312 extends to the second groove 402 and the second protrusion 322. The second shaft 312 is located at the end of the second groove 402. The third shaft 403 is located in the circular hole 325, the rib 326 is located in the slide groove 404, and the rib 326 does not enter the second groove 402. The second hinge member 32 and the slide 40 are relatively stationary.

[0180] Combine Figures 19 to 23 When the hinge assembly 30 is in the process of opening from a closed state to a first intermediate opening angle α11, the second hinge 32 and the slide 40 move relative to the first hinge 31, the first shaft 311 remains in the initial position A1, and the second shaft 312 moves within the first section L1 with the first shaft 311 as the center axis, and the door body 20 rotates in place, wherein the first intermediate opening angle α11 is approximately 10°.

[0181] Combine Figures 24 to 28 When the hinge assembly 30 is in the process of continuing to open from the first intermediate opening angle α11 to the second intermediate opening angle α12, the second hinge 32 and the slide 40 continue to move relative to the first hinge 31, and the second shaft 312 moves in the second section L2 to drive the first shaft 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 toward the accommodating chamber D.

[0182] Combine Figures 29 to 33 When the hinge assembly 30 is in the process of continuing to open from the second intermediate opening angle α12 to the first opening angle α1, the second hinge part 32 and the slide 40 continue to move relative to the first hinge part 31, and the second shaft 312 moves in the third section L3 and drives the first shaft 311 to move from the first stop position A2 to the second stop position A3. The door body 20 moves from the accommodating chamber D toward the pivot side P. Here, the first opening angle α1 is approximately 90°.

[0183] At this time, the first shaft 311 moves to the end of the first slot 401 , and the second shaft 312 moves to the end of the second slot 402 , so that the sliding plate 40 cannot continue to rotate relative to the first hinge 31 .

[0184] Combine Figures 34 to 38 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 door body 20 continues to apply force to the second hinge member 32, and the second hinge member 32 rotates relative to the slide 40.

[0185] Specifically, the first shaft 311 moves at the first extension portion 323 with the second rotation axis P2 (that is, the third shaft 403) as the center axis, and the second shaft 312 moves at the second extension portion 324 with the second rotation axis P2 as the center axis. At the same time, the rib 326 moves in the slide groove 404 and passes through the second groove body 402. The rib 326 cooperates with the end of the second groove body 402 to limit the second shaft body 312, that is, a portion of the second shaft body 312 abuts the end of the second body 402, and the other portion of the second shaft body 312 is tangent to the rib 326.

[0186] Then, when the ridge 326 moves in the sliding groove 404 to the end of the sliding groove 404 , the door body 20 reaches the maximum opening angle.

[0187] In other embodiments, combined Figures 39 to 42 The hinge assembly 30' further includes two shafts 311', 312' located on the first hinge member 31', two grooves 401', 402' located on the slide 40', a limiting protrusion 321' located on the second hinge member 32' and a rotating assembly 50' located between the slide 40' and the second hinge member 32'.

[0188] When the hinge assembly 30' is in a closed state, one of the shafts 311' extends to one of the grooves 401' and the limiting protrusion 321', and the central axis of the shaft 311' during rotation does not coincide with the central axis of the rotating assembly 50' during rotation, wherein the other shaft 312' extends into the other groove 402', and the other shaft 312' is spaced apart from the second hinge part 32', and the slide 40' and the second hinge part 32' are relatively stationary. When the hinge assembly 30' is in the opening process, the second hinge part 32' and the slide 40' move relative to the first hinge part 31' until the shafts 311' and 312' are limited to the grooves 401' and 402', and then the rotating assembly 50' drives the second hinge part 32' to move relative to the slide 40'.

[0189] Here, “the other shaft 312 ′ is spaced apart from the second hinge 32 ′” means that the shaft 312 ′ does not extend to the second hinge 32 ′.

[0190] In this embodiment, the locking and unlocking between the first hinge member 31', the second hinge member 32' and the slide 40' can be controlled by the structure of the hinge assembly 30'. Specifically, the second hinge member 32' and the slide 40' are first controlled to be locked with each other, and then the second hinge member 32' and the slide 40' are controlled to move relative to the first hinge member 31'. Then, the second hinge member 32' and the slide 40' are controlled to be unlocked and the first hinge member 31' and the slide 40' are locked with each other, and then the second hinge member 32' is controlled to move relative to the slide 40'.

[0191] In this embodiment, when the hinge assembly 30' is in the process of opening from a closed state to a first opening angle α1, the second hinge member 32' and the slide 40' rotate relative to the first hinge member 31' with the first rotation axis 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 member 32' rotates relative to the slide 40' with the second rotation axis P2 as the center axis. The second rotation axis P2 is staggered with the first rotation axis P1, that is, the position of the second rotation axis P2 is inconsistent with the position of the first rotation axis P1.

[0192] In addition, the hinge assembly 30' includes a first shaft 311' and a second shaft 312' provided on the first hinge part 31', and a first groove 401' and a second groove 402' provided on the slide 40'. The first groove 401' cooperates with the first shaft 311', and the second groove 402' cooperates with the second shaft 312'.

[0193] In the first specific example of this embodiment, Figures 39 to 40 When the hinge assembly 30' is in the closed state, the limiting protrusion 321' matches the first groove 401', the first shaft 311' extends to the first groove 401' and the limiting protrusion 321', and the second shaft 312' only extends to the second groove 402'. The second shaft 312' and the second hinge member 32' are spaced apart.

[0194] Here, when the hinge assembly 30' is in the process of opening from a closed state to a first opening angle α1, since the central axis of the rotation of the first shaft 311' and the second shaft 312' (i.e., the first rotation axis P1) does not coincide with the central axis of the rotation of the rotating assembly 50' (i.e., the second rotation axis P2), when the first shaft 311' rotates within the limiting protrusion 321', the rotating assembly 50' cannot drive the second hinge component 32' to rotate relative to the slide 40', that is, at this time the second hinge component 32' and the slide 40' are relatively stationary.

[0195] 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' also has an extension portion 323' connected to the limiting protrusion 321', the first shaft 311' moves at the extension portion 323' with the second rotation axis P2 as the center axis, thereby driving the second hinge member 32' to rotate relative to the slide 40'.

[0196] In the second specific example, combined with Figures 41 to 42 When the hinge assembly 30' is in a closed state, the limiting protrusion 322' matches the second groove 402', the second shaft 312' extends to the second groove 402' and the limiting protrusion 322', the first shaft 311' only extends to the first groove 401', and the first shaft 311' and the second hinge member 32' are spaced apart.

[0197] Here, when the hinge assembly 30' is in the process of opening from a closed state to a first opening angle α1, since the central axis of the rotation of the first shaft 311' and the second shaft 312' (i.e., the first rotation axis P1) does not coincide with the central axis of the rotation of the rotating assembly 50' (i.e., the second rotation axis P2), when the second shaft 312' rotates at the limiting protrusion 322', the rotating assembly 50' cannot drive the second hinge component 32' to rotate relative to the slide 40', that is, at this time the second hinge component 32' and the slide 40' are relatively stationary.

[0198] 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' also has an extension portion 324' connected to the limiting protrusion 322', the second shaft body 312' moves in the extension portion 324' with the second rotation axis P2 as the center axis, thereby driving the second hinge member 32' to rotate relative to the slide 40'.

[0199] It can be seen that the difference between this embodiment and the previous embodiment is that: in this embodiment, only one limiting protrusion is provided on the second hinge member 32', that is, the second hinge member 32' is only provided with a limiting protrusion 321' that cooperates with the first shaft body 311', or a limiting protrusion 322' that cooperates with the second shaft body 312'. At this time, the second hinge member 32' and the slide 40' can be coordinated with the rotating component 50' to achieve relative stillness.

[0200] The detailed description of the rotating assembly 50 ′ of this embodiment can be referred to the first embodiment, and will not be repeated here.

Although the present invention has been described in detail with reference to preferred embodiments, for example, if the techniques in different embodiments can be used in combination to simultaneously achieve corresponding effects, such solutions are also within the scope of protection of the present invention.
