[0042] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0043] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0044] One embodiment of the present invention provides a refrigerator, comprising any one of the following storage components.

[0045] The refrigerator may include storage compartments of different temperature zones, and a refrigerator door for opening and closing the storage compartments. Usually, a refrigerator is provided with a refrigerating compartment with a temperature higher than 0 degrees Celsius and a freezing compartment with a temperature lower than 0 degrees Celsius, and a refrigerator door for opening and closing the corresponding refrigerating compartment and freezing compartment. In one embodiment, the storage assembly may be used to form the refrigerator door and the refrigerating compartment or the freezing compartment.

[0046] One embodiment of the present invention provides a storage component, such as Figure 1 and Figure 2 As shown, it includes a box body 100, a door body 200 and a hinge assembly 300. The door body 200 is pivotally connected to the opening side 10 of the box body 100 through the hinge assembly 300, so as to realize the opening and closing of the internal storage space of the box body 100 by the door body 200.

[0047] The hinge assembly used to realize the opening and closing of the door body, when the storage assembly is arranged in the vertical direction, can include an upper hinge assembly located on the side of the door body 200 opposite to the upper end, and a lower hinge assembly located on the side of the lower end of the door body 200.

[0048] In one embodiment, the upper hinge assembly and the lower hinge assembly can be configured as the same structure. In one embodiment, the upper hinge assembly and the lower hinge assembly can have different structures. The latter embodiment is adopted in the preferred embodiment of the present invention, combined with Figure 1 As shown, the storage assembly includes an upper hinge assembly 300 and a lower hinge assembly 500. Based on this, if not particularly emphasized, the hinge assembly 300 described herein may indicate one of the upper hinge assembly or the lower hinge assembly, or only indicate the upper hinge assembly.

[0049] Figure 2 is a top view of the storage assembly when the door body 200 is at a first angle, Figure 3 yes Figure 2 A partial enlarged view of area A in the middle. It can be understood that Figures 4 to 6 , Fig.10 The same corresponds to Figure 2The partial enlarged view of the area A in the middle indicates the states of the door body 200 when it is at other angles.

[0050] Figure 3 An embodiment of the present invention is shown, in which a hinge assembly 300 includes a first shaft 31 , a second shaft 32 , and a hinge slot 2 matched with the first shaft 31 and the second shaft 32 .

[0051] In one embodiment, the first axis 31 and the second axis 32 jointly control the rotation state of the door body 200, and in particular, the first axis 31 and the second axis 32 can jointly control the state of the door body 200 rotating with different rotation centers. In some embodiments, the first axis 31 and the second axis 32 can also be used to control the translation state of the door body 200, such as translation toward or away from one side of the box body 100, or translation toward or away from the opening side. Specifically, the reason why the first axis 31 and the second axis 32 form the above control is the relative position constraint relationship between the two axes and the hinge slot 2, and the relative position constraint relationship between the two axes.

[0052] In one embodiment, the hinge slot 2 includes at least two slot sections. For example, Figure 4 The first slot section 2A and the second slot section 2B shown in FIG. 2A; the first shaft 31 may have a stage of moving along the first slot section 2A or at least being located in the first slot section 2A, and the second shaft 32 may have a stage of moving along the second slot section 2B or at least being located in the second slot section 2B, so that the door body 200 can pivot. For example, Figure 5 The second slot segment 2B and the third slot segment 2C are shown in the figure; the first axis 31 may exist in a stage of moving along the third slot segment 2C or at least being located in the third slot segment 2C, and the second axis 32 may exist in a stage of moving along the second slot segment 2B or at least being located in the second slot segment 2B, so as to make the door body 200 pivot.

[0053] The ends of the two slot sections are connected. Figure 4 The first slot segment 2A is connected to the end of the second slot segment 2B, and specifically, the end of the first slot segment 2A is connected to the head of the second slot segment 2B. Figure 5 The ends of the second slot segment 2B and the third slot segment 2C are connected, and specifically, the head of the second slot segment 2B is connected to the head of the third slot segment 2C. Fig.14 The ends of the first slot segment 2A and the third slot segment 2C are connected, and specifically, the end of the first slot segment 2A is connected to the head of the third slot segment 2C.

[0054] During the pivoting of the door body 200, there is a stage between the first shaft 31 and the second shaft 32 relative to the door body 200: the second shaft 32 is located in one of the two groove sections, and the first shaft 31 moves along the other of the two groove sections. In this way, the second shaft 32 and the first shaft 31 at least have different movement trends, forming a restraining relationship between each other, and combined with the connection of the ends of the two groove sections, the smoothness of door opening can be improved, the sense of frustration when opening the door can be alleviated, and the door opening process can be maintained stable.

[0055] In the above-mentioned pivoting process of the door body, there is a stage where the depth of the groove section where the second shaft 32 is located is greater than the depth of the groove section where the first shaft 31 is located. Figure 3 In the embodiment, the depth of the second slot section 2B where the second axis 32 is located is greater than the depth of the first slot section 2A where the first axis 31 is located. Figure 5 In the embodiment, the depth of the second slot section 2B where the second shaft 32 is located is greater than the depth of the third slot section 2C where the first shaft 31 is located. Thus, the first shaft 31 is prevented from occupying the movement space of the second shaft 32 and from falling into the second slot section 2B; the contact area between the second shaft 32 and the second slot section 2B is increased, and the pivoting stability and the anti-seismic performance of the hinge structure are improved; during assembly, the second shaft 32 can be first assembled to the deeper second slot section 2B, and then the first shaft 31 can be assembled to the first slot section 2A or the third slot section 2C, which plays the role of assembly correction and guidance.

[0056] In one embodiment, the first shaft 31 and the second shaft 32 are fixed to the box body 100 to take into account the cleaning, assembly, life and processing technology of the shaft groove; correspondingly, the hinge groove 2 is fixed to the door body 200, which is convenient for adjusting the structure of the hinge groove 2 and even realizing the configuration of a replaceable hinge groove 2, while taking into account the advantages of shaft groove cleaning, assembly, life and processing technology.

[0057] like Figures 2 to 6 , Fig.10 , Fig.14 and Fig.15 As shown, the door body 200 includes a door side wall 21 close to the side environment part 400 when the door is closed. In other words, the storage assembly can be arranged close to the side environment part 400, and can be arranged on one side of the side environment part 400, and the door body 200 and the box body 100 are arranged on the same side of the side environment part 400. The side environment part 400 can be a wall, a cabinet wall or even other door bodies or box body structures. That is, the storage assembly provided by the present invention can be applied to household appliances that need to be attached to other wall surfaces, for example, it can be applied to embedded equipment.

[0058] The first axis 31 has a first distance from the door sidewall 21, and the second axis 32 has a second distance from the door sidewall 21. During the opening process of the door body 200, there is a stage in which the sum of the first distance and the second distance decreases.

[0059] In one case, both the first distance and the second distance decrease; for example, the first shaft 31 moves in the first slot section 2A, and the second shaft 32 moves in the second slot section 2B. In one case, the magnitude of the decrease in the first distance is greater than the magnitude of the increase in the second distance; in one case, the magnitude of the increase in the first distance is less than the magnitude of the decrease in the second distance.

[0060] In this way, the door side wall 21 moves relatively close to the first axis 31 and the second axis 32, which is equivalent to the door side wall 21 moving away from the side environment part 400, so that when the door body is pivoted open, it moves horizontally close to the opening side to avoid interference with the side environment part 400, which can be applied in embedded scenarios.

[0061] In one embodiment, when the door is closed, the first shaft 31 is located on a side of the second shaft 32 away from the door side wall 21 .

[0062] In one embodiment, if Figure 3 , Figure 4 Combination Figures 7 to 9 As shown, the length e of the first axis 31 is less than the length E of the second axis 32. The hinge groove 2 includes a first groove section 2A and a second groove section 2B connected end to end; the end of the first groove section 2A is connected to the head of the second groove section 2B. The depth Hb of the second groove section 2B is greater than the depth Ha of the first groove section 2A.

[0063] During the pivoting of the door body 200, there is a stage in which the first shaft 31 moves along the first slot section 2A relative to the door body 200. During the opening of the door body, there is a stage in which the second shaft 32 moves along the second slot section 2B relative to the door body 200. In one embodiment, during the opening of the door body 200, the above two stages exist at the same time, and the two stages are performed simultaneously.

[0064] Since the second slot section 2B is deeper, the stability of the pivoting process can be maintained, and the first shaft 31 is prevented from encroaching on the movement space. Since the first slot section 2A and the second slot section 2B are connected end to end, the extension direction of the two slot sections as a whole can be adjusted, so that the door body 200 can be translated to a certain extent while pivoting. Since the first slot section 2A and the second slot section 2B are connected end to end, the opening progress of the door body 200 can be continuous and smooth.

[0065] In one embodiment, the first slot section 2A and the second slot section 2B extend in different directions. In this way, the two axis movements are mutually restricted, and the door body 200 can be opened smoothly.

[0066] In one embodiment, the first connecting section 71 between the first slot section 2A and the second slot section 2B is stepped; the flange of the first connecting section 71 is configured as an arc chamfer; the flange of the first connecting section 71 is configured as a concave arc chamfer, and is specifically concave toward the bottom of the deeper second slot section 2B. In this way, the smoothness of the first shaft 31 switching slot sections can be improved; specifically, the smoothness of the first shaft 31 switching from the first slot section 2A to the third slot section 2C can be improved, and even the smoothness of the first shaft 31 switching from the first slot section 2A to the third slot section 2C can be improved.

[0067] The door body 200 includes a door side wall 21 that is adjacent to the side environment member 400 when the door is closed.

[0068] The door body 200 includes a door front wall 22 facing away from the box body 100 when the door is closed.

[0069] In one embodiment, if Figure 3 , Figure 4 and Fig.14 In the process of the door body 200 pivoting and opening from the first angle α1 to the second angle α2, the first shaft 31 moves from the first guide position P1 of the first slot section 2A to the second guide position P2 relative to the door body 200. The second guide position P2 is located at the side of the first guide position P1 close to the door side wall 21. The second guide position P2 is located at the side of the first guide position P1 away from the door front wall 22.

[0070] The first guide position P1 is a slot in the hinge slot 2; the first guide position P1 is a slot in the first slot section 2A; the first guide position P1 points to the head of the first slot section 2A. The second guide position P2 is a slot in the hinge slot 2; the second guide position P2 is a slot at the junction of the second slot section 2B and the first slot section 2A; in one embodiment, the second guide position P2 is a slot in the second slot section 2B, the depth is deeper than the first guide position P1 (specifically, it can be the depth Hb), and when the door is closed, it is closer to the door side wall and / or farther away from the door front wall relative to the head of the second slot section 2B.

[0071] Of course, in other embodiments, the second guide position P2 may also point to the head of the second slot segment 2B; the second guide position P2 may also be a slot in the first slot segment 2A, and the second guide position P2 may also point to the end of the first slot segment 2A.

[0072] In one embodiment, if Figure 3 , Figure 4 and Fig.15In the process of the door body 200 pivoting and opening from the first angle α1 to the second angle α2, the second shaft 32 moves from the first driving position Q1 of the second slot section 2B to the second driving position Q2 of the second slot section 2B relative to the door body 200. The second driving position Q2 is located at the side of the first driving position Q1 close to the door side wall 21. The second driving position Q2 is located at the side of the first driving position Q1 close to the door front wall 22.

[0073] The first driving position Q1 is a slot in the hinge slot 2; the first driving position Q1 is a slot in the second slot section 2B, and the first driving position Q1 points to the head of the second slot section 2B. The second driving position Q2 is a slot in the hinge slot 2; the second driving position Q2 is a slot in the second slot section 2B; the second driving position Q2 points to the end of the second slot section 2B.

[0074] Of course, in other embodiments, the first driving position Q1 may also be a slot in the first slot section 2A, and the first driving position Q1 may also point to the end of the first slot section 2A.

[0075] In this way, relative to the door body 200, both axes move closer to the door side wall 21. When the door body 200 pivots open, there is a movement component along the first direction F1 closer to the opening side relative to the box body 100, thereby avoiding the side environmental component 400 on the other side.

[0076] The storage assembly provided by the present invention cooperates with the hinge assembly 300, especially the first shaft 31, the second shaft 32 and the hinge groove 2, so that the door body 200 moves inward relative to the opening side at least during the process of opening from the first angle α1 to the second angle α2. The hinge assembly 300 cooperates, especially the first shaft 31, the second shaft 32 and the hinge groove 2, so that the door body 200 moves inward relatively away from the side environment member 400 at least during the process of opening from the first angle α1 to the second angle α2.

[0077] The first direction F1 may be defined as a direction perpendicular to the door side wall 21 when the door is closed and pointing toward the opening side.

[0078] The second driving position Q2 is located at a side of the first guiding position P1 close to the door side wall 21 ; the second driving position Q2 is located at a side of the first guiding position P1 away from the door front wall 22 .

[0079] like Figure 4 When the door body 200 pivots to the second angle α2, the first shaft 31 is located at the second guide position P2; the second guide position P2 is located at the junction of the second slot section 2B and the third slot section 2C. When the door body 200 continues to pivot and open from the second angle α2, there is a stage where the first shaft 31 moves along the third slot section 2C. In this way, the first shaft 31 uses the second slot section 2B as a transition and can smoothly switch from the first slot section 2A to the third slot section 2C.

[0080] When the door body 200 pivots to the second angle α2, the second shaft 32 is located at the second driving position Q2 of the second slot section 2B; the second driving position Q2 is located at the end of the second slot section 2B close to the door side wall 21. The first shaft 32 reaches a maximum degree of movement relatively close to the door side wall 21 at the initial stage of door opening, which assists the door body 200 in quick avoidance and provides a larger design space for subsequent movement.

[0081] When the door body 200 pivots to the second angle α2, the first shaft 31 is located at the second guide position P2, and the second shaft 32 is located at the second driving position Q2 of the second slot section 2B. The second driving position Q2 is located at the second guide position P2 close to the door side wall 21. The second driving position Q2 is located at the second guide position P2 close to the door front wall 22.

[0082] When the door body 200 pivots and opens from the first angle α1 to the second angle α2, the first shaft 31 moves from the first guide position P1 to the second guide position P2, and the second shaft 32 moves from the first driving position Q1 to the second driving position Q2 relative to the door body 200.

[0083] Based on this, in one embodiment, the distance between the first guide position P1 and the second guide position P2 is greater than the distance between the first axis 31 and the second axis 32 .

[0084] Based on this, in one embodiment, the second guide position P2 is located at a side of the first driving position Q1 close to the door side wall 21 ; the second guide position P2 is located at a side of the first driving position Q1 away from the door front wall 22 .

[0085] Based on this, another embodiment is a combination of the solutions provided by the above two embodiments.

[0086] In one embodiment, relative to the door body 200, when the second shaft 32 moves along one of the two groove sections, the center point of the shaft moves to form a trajectory line; for example, when the second shaft 32 moves in the second groove section 2B, the center point of the second shaft 32 or the projection of its center line on the bottom of the hinge groove 2 moves accordingly to form a second trajectory line 6B. Relative to the door body 200, when the first shaft 31 moves along the other of the two groove sections, the center point of the shaft moves to form another trajectory line; for example, when the first shaft 31 moves in the first groove section 2A, the projection of the center point of the first shaft 31 or its center line on the bottom of the hinge groove 2 moves accordingly to form a first trajectory line 6A (in some embodiments, the first trajectory line 6A may also include a portion formed by the movement of the first shaft 31 in the second groove section 2B); for example, when the first shaft 31 moves in the third groove section 2C, the center point of the first shaft 31 or the projection of its center line on the bottom of the hinge groove 2 moves accordingly to form a third trajectory line 6C.

[0087] Based on this, in one embodiment, the average curvature of the second track line 6B is greater than the average curvature of the first track line 6A, so as to realize the movement combination of translation and pivoting of the door body 200.

[0088] In a further embodiment, a combination of several features in the above embodiment is included, that is, in this embodiment, a combination of the relationship between the first axis 31, the second axis 32, the first slot segment 2A and the second slot segment 2B defined in the above embodiment is satisfied.

[0089] One implementation method, such as Figures 5 to 9 As shown, the length e of the first axis 31 is smaller than the length E of the second axis 32 .

[0090] The first shaft 31 and the second shaft 32 are formed on the hinge plate 30. The first shaft 31 and the second shaft 32 are fixed to the box body 100 through the hinge plate 30. The hinge plate 30 includes a support plate 303; the length e of the first shaft 31 is interpreted as the length of the shaft structure extending from the support plate 303; the length E of the second shaft 32 is interpreted as the length of the shaft structure extending from the support plate 303.

[0091] Combination Figure 4 , the first slot section 2A and the second slot section 2B are arranged to form a semi-enclosed area. The support plate 303 includes a limiting side surface 301 near the semi-enclosed area. The semi-enclosed area can be provided with a wiring hole, and the wire is attached to the surface of the hinge plate 30 facing away from the box body 100 and extends into the wiring hole. The wire is at least partially overlapped with the limiting side surface 301 to be restricted by the movable position. Of course, the two shafts can also be configured as a hollow structure, and the wire passes through the hollow part of the shaft from the box body 100 and extends into the door body 200.

[0092] The hinge plate 30 includes a fixing plate 302 for fixing it to the box body 100. The fixing plate 302 is closer to the box body 100 than the supporting plate 303; the fixing plate 302 is directly fixed to the box body 100; and a gap is formed between the supporting plate 303 and the box body 100. The fixing plate 302 is connected to the supporting plate 303, and a connecting piece 304 formed by bending is included therebetween to ensure a smooth transition between the fixing plate 302 and the supporting plate 303.

[0093] The hinge groove 2 includes a second groove section 2B and a third groove section 2C.

[0094] During the process of opening the door body 200, there is a stage in which the first shaft 31 moves along the third slot segment 2C relative to the door body 200. During the process of opening the door body, there is a stage in which the second shaft 32 is located in the second slot segment 2B relative to the door body 200. In one embodiment, during the process of opening the door body 200, the above two stages exist at the same time, and the two stages are performed simultaneously.

[0095] The head of the second slot segment 2B is connected to the head of the third slot segment 2C; the head of the second slot segment 2B is at least partially connected to the head of the third slot segment 2B. When the hinge slot 2 is provided on the door body 200, the end of the second slot segment 2B away from the door side wall 21 and / or away from the door front wall 22 may be connected to the end of the third slot segment 2C away from the door side wall 21 and / or close to the door front wall 22. The two shafts are located in the two bifurcated slot segments and move smoothly according to the designed trajectory, so that the door body 200 pivoting and opening process is more stable.

[0096] The depth Hb of the second slot segment 2B is greater than the depth Hc of the third slot segment 2C. On the one hand, the third slot segment 2C forms a space relatively independent of the second slot segment 2B, ensuring the stable movement and / or rotation of the second shaft 32 located in the second slot segment 2B; on the other hand, it prevents the first shaft 31 from moving abnormally or having difficulty in switching at the position where the second slot segment 2B and the third slot segment 2C meet, or even encroaching on the movement space of the second shaft 32 in the hinge slot 2.

[0097] When the door is closed, the first shaft 31 is located at the side of the second shaft 32 away from the door side wall 21 ; when the door is closed, the first shaft 31 is located at the side of the second shaft 32 close to the door front wall 22 .

[0098] The second slot section 2B and the third slot section 2C are formed on the slot mounting block 7. The hinge slot 2 is fixed to the door body 200 through the slot mounting block 7. The slot mounting block 7 includes a mounting plate 70; the depth Hc of the third slot section 2C can also be interpreted as the height of the slot structure protruding from the mounting plate 70; the depth H of the second slot section 2B can also be interpreted as the height of the slot structure protruding from the mounting plate 70.

[0099] In one embodiment, the second slot section 2B and the third slot section 2C extend in different directions. In this way, the two axis movements are mutually restricted, and the door body 200 can be opened smoothly.

[0100] In one embodiment, the second connecting section 72 between the second slot section 2B and the third slot section 2C is stepped; the flange of the second connecting section 72 is configured as an arc chamfer; the flange of the second connecting section 72 is configured as an outwardly convex arc chamfer, and specifically convexly away from the bottom of the second slot section 2B which is deeper. In this way, the smoothness of the first shaft 31 switching slot sections can be improved; specifically, the smoothness of the first shaft 31 switching from the first slot section 2A to the third slot section 2C can be improved, and even the smoothness of the first shaft 31 switching from the first slot section 2A to the third slot section 2C can be improved.

[0101] The door body 200 includes a door side wall 21 that is adjacent to the side environment member 400 when the door is closed.

[0102] The door body 200 includes a door front wall 22 facing away from the box body 100 when the door is closed.

[0103] In one embodiment, if Figures 4 to 6 and Fig.14 In the process of the door body 200 pivoting and opening from the second angle α2 to the third angle α3, the first shaft 31 moves from the second guide position P2 to the third guide position P3 of the third slot section 2C relative to the door body 200. The third guide position P3 is located at the side of the second guide position P2 close to the door side wall 21. The third guide position P3 is located at the side of the second guide position P2 away from the door front wall 22.

[0104] The second guide position P2 is a slot in the hinge slot 2; the second guide position P2 is a slot at the intersection of the second slot section 2B and the first slot section 2A; in one embodiment, the second guide position P2 is a slot in the second slot section 2B, the depth is deeper than the first guide position P1 (specifically, it can be the depth Hb), and when the door is closed, it is closer to the door side wall and / or farther away from the door front wall relative to the head of the second slot section 2B. The third guide position P3 is a slot in the hinge slot 2; the third guide position P3 is a slot in the third slot section 2C; the third guide position P3 points to the extreme position of the first axis 31 in the third slot section 2C. In one embodiment, as Figure 6 , the third guide position P3 points to the end of the third slot section 2C. In another embodiment, as Fig.10 , the third guide position P3' points to the middle of the third slot section 2C.

[0105] Of course, in other embodiments, the second guide position P2 may also point to the head of the second slot segment 2B; the second guide position P2 may also be a slot in the first slot segment 2A, and the second guide position P2 may also point to the end of the first slot segment 2A.

[0106] In one embodiment, if Figures 4 to 6 and Fig.15 During the process of the door body 200 pivoting and opening from the second angle α2 to the third angle α3, the second shaft 32 is maintained at the second driving position Q2 of the second slot section 2B relative to the door body 200.

[0107] The second driving position Q2 is a slot position in the second slot section 2B, and the second driving position Q2 points to the end of the second slot section 2B. In this way, the pivoting opening angle of the door body 200 is deepened.

[0108] like Figure 4 When the door body 200 pivots to the second angle α2, the first shaft 31 is located at the second guide position P2; the second guide position P2 is located at the junction of the second slot segment 2B and the first slot segment 2A. In the process of the door body 200 pivoting from the first angle α1 to the second angle α2, there is a stage in which the first shaft 31 moves along the first slot segment 2A relative to the door body 200. In this way, the first shaft 31 uses the second slot segment 2B as a transition and can smoothly switch from the first slot segment 2A to the third slot segment 2C.

[0109] When the door body 200 pivots to the second angle α2, the second shaft 32 is located at the second driving position Q2 of the second slot section 2B; the second driving position Q2 is located at the end of the second slot section 2B close to the door side wall 21. The first shaft 32 remains at a position close to the door side wall 21 in the later stage of door opening, so that the door body 200 deepens the pivoting amplitude at the innermost side (the side closest to the opening side) in the first direction F1. The first direction F1 can be defined as a direction perpendicular to the door side wall 21 when the door is closed and pointing to the opening side.

[0110] When the door body 200 pivots to the third angle α3, the second shaft 32 is located at the second driving position Q2 of the second slot section 2B, and the first shaft 31 is located at the third guide position P3 of the third slot section 2C. The second driving position Q2 is located at the third guide position P3 close to the door front wall 22. In one embodiment, Fig.10 , Fig.14 and Fig.15 , the second driving position Q2 is located at the third guide position P3' close to the door side wall 21; in another embodiment, as Figure 6 , Fig.14 and Fig.15 The second driving position Q2 is located on the side of the third guiding position P3 away from the door side wall 21.

[0111] In one embodiment, relative to the door body 200, when the first axis 31 moves along one of the two groove segments, the center point of the axis moves to form a trajectory line; for example, when the first axis 31 moves in the third groove segment 2C, the center point of the first axis 31 or the projection of its center line on the bottom of the hinge groove 2 moves accordingly to form a third trajectory line 6C.

[0112] In one embodiment, the third track line 6C is an arc line; in particular, the third track line 6C is a circular arc line.

[0113] In one embodiment, the third track line 6C is an arc line, and the center of the arc is located at the second driving position Q2 of the second slot section 2B. When the door body 200 pivots to the second angle α2, the second shaft 32 is located at the second driving position Q2.

[0114] In one embodiment, the third trajectory line 6C is an arc line, and the radius is equal to the distance between the first axis 31 and the second axis 32 .

[0115] Relative to the door body 200, when the second shaft 32 moves along one of the two groove sections, the center point of the shaft moves to form a trajectory line; for example, when the second shaft 32 moves in the second groove section 2B, the projection of the center point of the second shaft 32 or its center line on the bottom of the hinge groove 2 moves accordingly to form a second trajectory line 6B.

[0116] Based on this, in one embodiment, the average curvature of the second track line 6B is greater than the average curvature of the third track line 6C, so that the door body 200 can achieve a combined movement of translation and pivoting as well as a pivoting movement.

[0117] In a further embodiment, a combination of several features in the above embodiment is included, that is, in this embodiment, a combination of the relationship between the first axis 31, the second axis 32, the second slot segment 2B and the third slot segment 2C defined in the above embodiment is satisfied.

[0118] In one embodiment, if Figures 3 to 8 and Fig.10 As shown, the hinge groove 2 includes a first groove section 2A and a third groove section 2C connected end to end; the end of the first groove section 2A is connected to the head of the third groove section 2C. The depth Ha of the first groove section 2A is greater than the depth Hc of the third groove section 2C.

[0119] During the pivoting of the door body 200, there is a stage in which the first shaft 31 moves along the first slot segment 2A and the third slot segment 2C in sequence relative to the door body 200. In one embodiment, during the pivoting opening of the door body 200, there is a stage in which the first shaft 31 moves along the first slot segment 2A and the third slot segment 2C in sequence; in one embodiment, during the pivoting closing of the door body 200, there is a stage in which the first shaft 31 moves along the third slot segment 2C and the first slot segment 2A in sequence.

[0120] Since the third groove section 2C is shallower, it can ensure that the first shaft 31 is smoothly limited and switched from other deeper groove sections to the third groove section 2A.

[0121] In one embodiment, when the first shaft 31 moves in the third slot section 2C, the door body 200 pivots around the second shaft 32; therefore, the third slot section 2C is shallower, which can ensure the stability of the in-situ pivoting process. In one embodiment, when the first shaft 31 moves in the first slot section 2A, the door body 200 pivots while moving toward or away from the opening side, and the second shaft 32 moves away from or toward the opening side relative to the door body 200; therefore, the first slot section 2A is deeper, which can ensure that during the composite movement, the two shafts will not have difficulty in movement due to excessive mutual restriction.

[0122] In one embodiment, the first slot section 2A and the third slot section 2C extend in different directions, so that the first axis 31 can be directed to change direction as the door body 200 pivots, so that the door body 200 can be opened at a larger angle.

[0123] In one embodiment, the door body 200 includes a door front wall 22 that is away from the box body 100 when the door is closed. The third groove section 2C is deflected to the side away from the door front wall 22 compared to the first groove section 2A. In this way, the door body pivoting range is deepened, and the door body 200 is assisted to achieve the action path of first moving inward and then rotating in place, so as to prevent problems such as difficulty in taking objects due to excessive inward movement.

[0124] In one embodiment, during the movement of the first axis 31 along the first slot section 2A and the third slot section 2C in sequence, the curvature of the trajectory formed by the movement of the first axis 31 in the hinge slot 2 first gradually decreases and then remains unchanged. The trajectory, specifically the projection of the center point of the first axis 31 or its center line on the bottom of the hinge slot 2, is formed by the movement during the above movement. The curvature of the trajectory generated by the movement of the first axis 31 first gradually decreases, so that the translation component in the direction of approaching or moving away from the side environment part 400 and approaching or moving away from the box body 100 gradually increases while the door body pivots, especially in the embodiment where at least the first slot section 2A extends in the direction close to the door side wall 21 and away from the door front wall 22 when closing the door, in the middle of the movement along the above trajectory, the door body 200 can generate a large translation component away from the side environment part 400 and away from the box body 100, preventing the door body 200 from interfering with the surrounding structure, and can slow down the development process of the pivot, further preventing the door body 200 from interfering with the surrounding structure. In the later stage of the pivoting of the door body 200, the curvature of the above-mentioned trajectory line remains unchanged, and the door body 200 can rotate in situ to achieve rapid opening.

[0125] In one embodiment, relative to the door body 200, when the first shaft 31 moves in the first groove section 2A, the projection of the center point of the first shaft 31 or its center line on the bottom of the hinge groove 2 moves accordingly to form a first trajectory line 6A (in some embodiments, the first trajectory line 6A may also include a portion formed by the movement of the first shaft 31 in the second groove section 2B); when the first shaft 31 moves in the third groove section 2C, the projection of the center point of the first shaft 31 or its center line on the bottom of the hinge groove 2 moves accordingly to form a third trajectory line 6C.

[0126] Based on this, in one embodiment, the average curvature of the third trajectory line 6C is greater than the average curvature of the first trajectory line 6A, so that the door body 200 can pivot with a greater amplitude when the first axis 31 moves along the third trajectory line 6C.

[0127] Figure 5 The state when the door body 200 is opened to the middle angle α02 is shown, at which time the first shaft 31 moves to the middle guide position P02, and the second shaft 32 is located at the second driving position Q2. Figure 4 and Figure 6As shown, the door body 200 includes a door side wall 21 close to the side environment part 400 when the door is closed, and a door front wall 22 facing away from the box body 100 when the door is closed; the door side wall 21 and the door front wall 22 intersect to form a door outer edge 22, and when the door body 200 is opened to the middle angle α02, the door outer edge 22 is located at the middle outer edge position W02.

[0128] In one embodiment, the intermediate angle α02 is 90 degrees, or any angle between 85 degrees and 95 degrees.

[0129] When the door is closed, the door side wall 21 is flush with the corresponding side wall of the box body 100; in one embodiment, when pivoting to the middle angle α02, the door front wall 22 is located on the side of the above-mentioned side wall of the box body 100 close to the opening side in the first direction F1; in another embodiment, when pivoting to the middle angle α02, the door front wall 22 is flush with the above-mentioned side wall of the box body 100.

[0130] In one embodiment, when pivoting to the middle angle α02, the first axis 31 is located on the side of the second axis 32 away from the door front wall 22; in one embodiment, when pivoting to the middle angle α02, the first axis 31 is located on the side of the second axis 32 away from the door side wall 21.

[0131] In one embodiment, the intermediate angle α02 is greater than the second angle α2. In the process of the door body 200 pivoting from the second angle α2 to the intermediate angle α02, there is a stage in which the first axis 31 moves to form the intermediate track line 6C1. The intermediate track line 6C1 is an arc line; the center of the intermediate track line 6C1 is located at or near the axis center of the second axis 32; the radius of the intermediate track line 6C1 is equal to the distance between the first axis 31 and the second axis 32.

[0132] The middle track line 6C1 may be the third track line 6C, which means that the middle angle α02 is equal to the third angle α3; when the door body pivots to the middle angle α02, the first shaft 31 moves to the extreme position. The middle track line 6C1 may also be a part of the third track line 6C.

[0133] When the door body 200 is pivoted from the second angle α2 to the intermediate angle α02, there is a stage in which the door outer edge 24 moves to form the intermediate outer edge track segment L21. The intermediate outer edge track segment L21 is an arc line; the center of the intermediate outer edge track segment L21 is located at or near the axis of the second axis 32; the radius of the intermediate outer edge track segment L21 is equal to the distance between the first axis 31 and the second axis 32.

[0134] When the door body 200 is pivoted from the second angle α2 to the third angle α3, there is a stage in which the door outer edge 24 moves to form a second outer edge track L2. The second outer edge track L2 is an arc line; the center of the second outer edge track L2 is located at or near the axis of the second axis 32; the radius of the second outer edge track L2 is equal to the distance between the first axis 31u and the second axis 32.

[0135] The middle outer edge track segment L21 can be the second outer edge track L2, which means that the middle angle α02 is equal to the third angle α3; when the door body pivots to the middle angle α02, the first shaft 31 moves to the extreme position. The middle track line 6C1 can also be a part of the third track line 6C.

[0136] The door body 200 includes a door side wall 21 close to the side environment member 400 when the door is closed, and the hinge groove 2 includes a third groove section 2C. Figure 6 In the embodiment shown, the end of the third slot section 2C is limited by the position of the end close to the door side wall 21, and the end of the third slot section 2C is the limit position of the movement of the first shaft 31; Figures 10 to 13 In the illustrated embodiment, a limit block 81 is further provided in the hinge groove 2. When the door body 200 pivots to the third angle α3', the limit block 81 cooperates with the first shaft 31 to limit its movement so that it reaches the third limit position P3'. That is, in this embodiment, the movement of the first shaft 31 and the limit axis are limited by the limit block 81.

[0137] by Figures 10 to 13 As an example of the embodiment shown in the figure, in one embodiment, the restriction of the above-mentioned limit position can be released. After being released, when the door body is pivoted from the third angle α3' to the maximum angle (for example Figure 6 During the process of the first axis 31 moving from the third guide position P3' of the third groove section 2C to the third angle α3 shown in the figure, the first axis 31 continues to move along the third groove section 2C from the third guide position P3' of the third groove section 2C. At this time, the pivoting degree of the door body 200 can be further deepened, the third track line 6C formed by the movement of the first axis 31 in the third groove section 2C is further extended, and the second outer edge track L2 formed by the movement of the door outer edge 24 is further extended.

[0138] In one embodiment, when pivoting to Fig.10 When the third angle α3' is shown, the stopper 81 limits the first shaft 31 to the third guide position P3' located before the end of the third slot section 2C. After the stopper 81 is removed to release the limit position limit of the first shaft 31, the door body 200 continues to pivot open, and at least the following can be achieved in the end: Figure 6 In the state shown, the first shaft 31 is located at the end of the third slot section 2C. Figure 6 The third angle α3 shown may be defined as being the maximum angle.

[0139] In one embodiment, during the process of the door body 200 pivoting and opening from the third angle α3' to the maximum angle, the length of the third track line 6C formed by the movement of the first axis 31 is positively correlated with the maximum angle. The longer the third track line 6C is configured, the greater the maximum angle that the door body 200 can pivot to. In one embodiment, during the process of the door body 200 pivoting and opening from the third angle α3' to the maximum angle, the length of the second outer edge track L2 formed by the movement of the door outer edge 24 is positively correlated with the maximum angle. The greater the maximum angle that the door body 200 can pivot to, the longer the length of the second outer edge track L2.

[0140] The hinge groove 2 includes a first groove section 2A, a second groove section 2B and a third groove section 2C.

[0141] like Figure 3 and Figure 4 As shown, in the process of the door body 200 pivoting from the first angle α1 to the second angle α2, relative to the door body 200, there is a stage in which the first shaft 31 moves along the first slot section 2A and the second shaft 32 moves along the second slot section 2B. The first angle α1 is smaller than the second angle α2. In one embodiment, the second angle is one of 50 degrees to 60 degrees; in one embodiment, the first angle is one of -5 degrees to 5 degrees.

[0142] like Figures 4 to 6 Combined with Fig.10 As shown, when the door body 200 is pivoted from the second angle α2 to the maximum angle (such as Figure 6 During the process of reaching the third angle α3 shown in FIG. 1 , relative to the door body 200, there is a stage in which the first axis 31 moves along the third slot section 2C and the second axis 32 is located in the second slot section 2B. In one embodiment, the maximum angle is one of 90 degrees to 140 degrees.

[0143] like Figures 3 to 6 Combination Fig.10 As shown, the door body 200 is pivoted from the first angle α1 to a third angle (such as Figure 6 The third angle α3 shown, or Fig.10 During the process of adjusting the angle α3′ as shown in the figure, relative to the door body 200, there is a stage in which the first shaft 31 moves from the first slot segment 2A through the second slot segment 2B and enters the third slot segment 2C.

[0144] The door body 200 includes a door front wall 22 facing away from the box body 100 when the door is closed, and a door side wall 21 close to the side environment member 400 ; the door front wall 22 and the door side wall 21 meet to form a door outer edge 24 .

[0145] In one embodiment, if Figure 3 and Figure 4As shown, during the process of the door body 200 opening from the first angle α1 to the second angle α2, there is a stage in which the door outer edge 24 moves away from the side environment member 400. In this way, interference with the side environment member 400 is avoided.

[0146] like Figure 3 and Figure 4 Combined with Fig.14 and Fig.15 As shown, in one embodiment, during the process of the door body 200 pivoting from the first angle α1 to the intermediate angle, there is a stage in which the movement component of the door outer edge 24 in the first direction F1 decreases (eg, Figure 4 The first direction F1 is a direction away from the side environment member 400 , and can be a direction perpendicular to the side of the side environment member 400 close to the box body 100 and away from the side environment member 400 .

[0147] In one embodiment, the transition angle is one between 20 degrees and 30 degrees.

[0148] In one embodiment, during the process of the door body 200 pivoting from the first angle α1 to the intermediate angle, there is a stage in which the movement component of the door outer edge 24 in the second direction F2 increases (e.g. Figure 4 The second direction F2 is a direction approaching the box body 100, and in particular, may be a direction perpendicular to the box body front wall close to the door body 100 and approaching the box body 100.

[0149] The intermediate angle is greater than the first angle α1. When the door body 200 pivots to the intermediate angle, the second shaft 32 moves from the first driving position Q1 to the intermediate driving position Q01.

[0150] The intermediate driving position Q01 is located between the first driving position Q1 and the second driving position Q2. Relative to the door body 200, the intermediate driving position Q01 is located on the side of the first driving position Q1 close to the door side wall 21; the intermediate driving position Q01 is located on the side of the first driving position Q1 away from the door front wall 22.

[0151] The movement component of the door outer edge 24 in the first direction F1 gradually decreases from large to small at the initial stage of door opening, which can effectively avoid interference with the side environment component 400 and gradually increase the backward movement range to ensure continuous avoidance of interference while pivoting open.

[0152] In one embodiment, when the door body 200 is pivoted and opened from the first angle α1 to the intermediate angle, the door outer edge 24 moves from the first outer edge position W1 to the intermediate outer edge position W01 relative to the box body 100. The intermediate outer edge position W01 is located on the side of the first outer edge position W1 close to the box body 100; the intermediate outer edge position W01 is located on the side of the first outer edge position W1 away from the side environment member 400.

[0153] In one embodiment, when the door body 200 is pivoted and opened from the first angle α1 to the intermediate angle, the door outer edge 24 moves along the first front outer edge track L11 relative to the box body 100. The equivalent track center of the first front outer edge track L11 is located on the side of the first front outer edge track L11 close to the side environment member 400; the first front outer edge track L11 is convex toward the side away from the side environment member 400.

[0154] The first outer edge position W1 has a first outer edge distance (vertical distance) with the side environment element 400 ; the vertical distances between other points on the first front outer edge trajectory L11 except the first outer edge position W1 and the side environment element 400 are all smaller than the first outer edge distance.

[0155] In one embodiment, during the process of the door body 200 pivoting and opening from the intermediate angle to the second angle α2, there is a stage in which the movement component of the door outer edge 24 in the first direction F1 increases (eg, Figure 4 The first direction F1 is a direction away from the side environment member 400 , and can be a direction perpendicular to the side of the side environment member 400 close to the box body 100 and away from the side environment member 400 .

[0156] In one embodiment, during the process of the door body 200 pivoting and opening from the intermediate angle to the second angle α2, there is a stage in which the movement component of the door outer edge 24 in the second direction F2 decreases (eg, Figure 4 The second direction F2 is a direction approaching the box body 100, and in particular, may be a direction perpendicular to the box body 100 and close to the front wall of the box body 100 and close to the door body 100.

[0157] The intermediate angle is smaller than the second angle α2. When the door body 200 pivots to the intermediate angle, the second shaft 32 moves from the intermediate driving position Q01 to the second driving position Q2.

[0158] The intermediate driving position Q01 is located between the first driving position Q1 and the second driving position Q2. Relative to the door body 200, the intermediate driving position Q01 is located on the side of the second driving position Q2 away from the door side wall 21; the intermediate driving position Q01 is located on the side of the second driving position Q2 away from the door front wall 22.

[0159] The movement component of the door outer edge 24 in the second direction F2 gradually decreases in the middle stage of door opening, which can effectively avoid interference with the box body 100 (such as squeezing the door seal) and gradually increase the inward movement to ensure that interference is continuously avoided while pivoting open.

[0160] In one embodiment, when the door body 200 is pivoted and opened from the intermediate angle to the second angle α2, the door outer edge 24 moves from the intermediate outer edge position W01 to the second outer edge position W2 relative to the box body 100. The second outer edge position W2 is located on the side of the intermediate outer edge position W01 close to the box body 100; the second outer edge position W2 is located on the side of the intermediate outer edge position W01 away from the side environment member 400.

[0161] In one embodiment, when the door body 200 is pivoted and opened from the intermediate angle to the second angle α2, the door outer edge 24 moves along the first rear outer edge track L12 relative to the box body 100. The equivalent track center of the first rear outer edge track L12 is located on the side of the first rear outer edge track L12 away from the side environment member 400; the first rear outer edge track L12 is convex toward the side close to the side environment member 400.

[0162] The middle outer edge position W01 has a second outer edge distance (vertical distance) with the side environment component 400 ; the vertical distances between other points on the first rear outer edge trajectory L12 except the middle outer edge position W01 and the side environment component 400 are all less than the second outer edge distance.

[0163] In one embodiment, when the door body 200 opens from the first angle α1 to the second angle α2, there is a stage in which the movement component of the door outer edge 24 in the first direction F1 first decreases and then increases. The first direction F1 is the direction away from the side environment element 400.

[0164] In one embodiment, when the door body 200 is opened from the first angle α1 to the second angle α2, the movement component of the door outer edge 24 in the second direction F2 first increases and then decreases. The second direction F2 is the direction approaching the box body 100.

[0165] In one embodiment, when the door body 200 is pivoted from the first angle α1 to the second angle α2, the door outer edge 24 moves from the first outer edge position W1 to the second outer edge position W2 relative to the box body 100. The second outer edge position W2 is located on the side of the first outer edge position W1 close to the box body 100; the second outer edge position W2 is located on the side of the first outer edge position W1 away from the side environment member 400.

[0166] In one embodiment, when the door body 200 is pivoted from the first angle α1 to the second angle α2, the outer edge 24 of the door moves relative to the box body 100 to form a first outer edge trajectory L1. The first outer edge trajectory L1 is S-shaped. In one embodiment, the door body 200 is pivoted counterclockwise to open, and the first outer edge trajectory L1 is "reverse S-shaped"; in one embodiment, the door body 200 is pivoted clockwise to open, and the first outer edge trajectory L1 is "positive S-shaped".

[0167] The first outer edge position W1 has a first outer edge distance (vertical distance) with the side environment element 400 ; the vertical distances between other points on the first outer edge trajectory L1 except the first outer edge position W1 and the side environment element 400 are all smaller than the first outer edge distance.

[0168] like Figures 5 and 6 As shown, the door body 200 is pivoted from the second angle α2 to the third angle α3 (or Fig.10 In the process of pivoting and opening from the second angle α2 to the middle angle α02), there is a stage where the door outer edge 24 moves close to the side environment member 400. Specifically, in the process where the door outer edge 24 moves from the second outer edge position W2 to the third outer edge position W3 (or, from the second outer edge position W2 to the middle outer edge position W02), there is a stage where the door outer edge 24 moves close to the side environment member 400.

[0169] When the door body 200 is pivoted from the second angle α2 to the third angle α3 (or Fig.10 In the process of pivoting from the second angle α2 to the middle angle α02), there is a stage where the door outer edge 24 moves away from the side environment member 400. Specifically, when the door outer edge 24 moves from the second outer edge position W2 to the third outer edge position W3 (or Fig.10 or, in the process of moving from the second outer edge position W2 to the middle outer edge position W02), there is a stage in which the door outer edge 24 moves away from the side environment member 400.

[0170] In one embodiment, during the process of the door body 200 pivoting from the second angle α2 to the third angle α3, the door outer edge 24 always moves away from the side environment member 400. In one embodiment, during the entire process of the door body pivoting, the door outer edge 24 always moves away from the side environment member 400.

[0171] In one embodiment, the door body 200 is pivoted from the second angle α2 to the third angle α3 (or Fig.10In the process of pivoting from the second angle α2 to the middle angle α02), there is a stage where the door outer edge 24 first moves closer to the side environment member 400 and then moves away from the side environment member 400. Specifically, when the door outer edge 24 moves from the second outer edge position W2 to the third outer edge position W3 (or Fig.10 or, in the process of moving from the second outer edge position W2 to the middle outer edge position W02), there is a stage in which the door outer edge 24 first approaches and then moves away from the side environment member 400.

[0172] When the door body 200 is pivoted from the second angle α2 to the third angle α3 (or Fig.10 In the process of pivoting from the second angle α2 to the middle angle α02), there is a stage in which the movement component of the door outer edge 24 in the third direction F3 first decreases and then increases in the opposite direction (that is, the movement component in the first direction F1 increases), and the movement component of the door outer edge 24 in the second direction F2 first increases and then decreases. The third direction F3 is the direction close to the side environment member 400, the second direction F2 is the direction close to the box body 100, and the first direction F1 is the direction away from the side environment member 400.

[0173] During the process of the door body 200 pivoting and opening, there is a stage in which the door outer edge 24 moves close to the box body 100. In one embodiment, during the entire process of the door body 200 pivoting and opening, the door outer edge 24 always moves close to the box body 100.

[0174] like Figure 3 , Figure 4 Combination Fig.15 As shown, during the process of the door body 200 pivoting and opening from the intermediate angle to the second angle α2, the door outer edge 24 moves to form a first rear outer edge track L12. Figure 4 and Figure 6 As shown, during the process of the door body 200 pivoting from the second angle α2 to the third angle α3, the door outer edge 24 moves to form a second outer edge trajectory L2; of course, the second outer edge trajectory L2 can also point to a partial trajectory segment, for example, pivoting from the second angle α2 to the middle angle α02 (such as Figure 5 ) formed by the middle outer edge track segment L21, or refers to Fig.10 The shorter second outer edge trajectory L2' is formed in the process.

[0175] The average curvature of the second outer edge track L2 is greater than the average curvature of the first rear outer edge track L12. In this way, a more sufficient pivoting amount is formed in the later stage of door opening.

[0176] like Figures 3 to 6 Combination Fig.10As shown, during the process of the door body 200 pivoting to open, the outer edge 24 of the door moves to form an outer edge trajectory (specifically including a first outer edge trajectory L1 and a second outer edge trajectory L2). The outer edge trajectory is located at other positions of the door outer edge 24 after the outer edge closing position, and is located on the side of the outer edge closing position away from the side environment part 400. In one embodiment, the first angle α1 is 0 degrees; the first outer edge position W1 is the outer edge closing position, that is, the position of the outer edge 24 when the door is closed; other positions in the outer edge trajectory located after the first outer edge position W1 (for example, the intermediate outer edge position W01, the second outer edge position W2, the middle outer edge position W02, Figure 6 The third outer edge position W3 shown, Fig.10 The third outer edge position W3 ′) shown is located at the side of the first outer edge position W1 away from the side environment member 400 . In this way, the entire process of the door body 200 pivoting and opening at least will not interfere with the side environment member 400 .

[0177] The relationship among the door body 200 , the door outer edge 24 , the box body 100 and the side environment member 400 may be configured as one of the above-mentioned embodiments, or a combination of the above-mentioned embodiments.

[0178] The different extension directions can be interpreted as different overall directions. Figure 3 The first slot section 2A and the second slot section 2B have different shapes, curvatures, arcs, and curvature radii; for example Figure 3 Specifically, the third slot segment 2C is in the shape of a circular arc or approximately a circular arc, and the first slot segment 2A and the second slot segment 2B are in the shape of an irregular curve, an elliptical arc, or approximately an elliptical arc.

[0179] The track lines formed in the slot segments with different extension directions also have different extension directions or overall shapes. For example, the third track line 6C is an arc, and the first track line 6A and the second track line 6B are irregular curves or elliptical arcs. For example, when the user stands facing the door, the third track line 6C deflects away from the user relative to the first track line 6A, and the second track line 6B deflects towards the user relative to the first track line 6A.

[0180] like Figures 7 to 13As shown, the hinge assembly 300 includes a limit block 81 detachably connected to the hinge slot 2. During the pivoting of the door body 200, there is a stage in which the hinge axis (for example, the first axis 31 and / or the second axis 32) moves in the hinge slot 2 relative to the door body 200. During the pivoting of the door body 200, there is a state in which the hinge axis cooperates with the limit block 81, and when the two cooperate, the pivot angle between the door body 200 and the box body 100 is prevented from changing. In this way, the pivot angle of the door body 200 can be limited with a simple structure to prevent the door body from being over-opened or over-closed to cause a collision with other surrounding objects. In some embodiments, a certain degree of opening can also be maintained to facilitate the placement of items.

[0181] The preventing the pivot angle between the door body 200 and the box body 100 from changing may specifically prevent the pivot angle from increasing, or prevent the pivot angle from decreasing, or prevent the pivot angle from increasing and decreasing at the same time, so as to maintain it at a stable angle or angle range.

[0182] In one embodiment, the limit block 81 can be specifically used to limit the limit angle of the door body 200 pivoting. In one embodiment, the limit block 81 is used to limit the limit angle of the door body 200 pivoting to not greater than a first limit angle, and the first limit angle is less than or equal to the maximum angle of the door body 200 pivoting; in another embodiment, the limit block 81 is used to limit the limit angle of the door body 200 pivoting to not less than a second limit angle, and the second limit angle is greater than or equal to the minimum angle of the door body 200 pivoting.

[0183] The limiting angles such as the first limiting angle and the second limiting angle are set by the limiting block 81. Specifically, the limiting angles are set by the shape of the limiting block 81 and the setting position of the limiting block 81 in the hinge groove 2.

[0184] The hinge axis is fixed to the box body 100, and the door body 200 includes a door side wall 21 close to the side environment part 400 when the door is closed. In the process of the door body 200 pivoting to open, there is a stage in which the distance between the hinge axis and the door side wall 21 decreases. In an embodiment in which the hinge axis is configured as a single-axis system (including only one pivot axis), the distance may be the vertical distance between the pivot axis and the door side wall 21. In an embodiment in which the hinge axis is configured as a dual-axis or multi-axis system (including two or more axes, such as a first axis 31 and a second axis 32), the distance may be the sum or average of the vertical distances between the dual axes or multiple axes and the door side wall 21.

[0185] Since the distance between the hinge axis and the door side wall 21 is reduced, the door body 200 can generate at least a motion component perpendicular to the door side wall 21 when pivoting (specifically, it can generate a translation component in this direction while pivoting). In this way, the door body 200 can be moved outward to prevent the two doors of the double-door refrigerator from interfering with each other or insufficient release of the opening side access space; or the door body 200 can be moved inward to avoid interference with the side environment part 400, so as to be applied to embedded devices.

[0186] The hinge axis includes a first axis 31, and the hinge slot 2 includes a third slot section 2C.

[0187] In one embodiment, the limit block 81 is disposed in the third slot section 2C. Thus, the movement of the first shaft 31 in the third slot section 2C can be limited to limit the change in the pivot angle of the door body 200 and the box body 100.

[0188] During the pivoting of the door body 200, there is a stage in which the first shaft 31 moves in the third slot section 2C relative to the door body 200. During the pivoting of the door body 200, there is a state in which the first shaft 31 cooperates with the stop block 81, and when the two cooperate, at least the pivoting angle between the door body 200 and the box body 100 is prevented from increasing. In this way, the maximum angle (limit angle) that the door body 200 can reach when pivoting and opening can be adjusted by setting the stop block 81, and in particular, it can be used to prevent the door body 200 from interfering with the side environment member 400.

[0189] In one embodiment, the hinge axis (particularly the first axis 31 ) is fixed to the box body 100 , and the door body 200 includes a door side wall 21 close to the side environment member 400 when the door is closed.

[0190] In one embodiment, the stopper 81 is disposed at the end of the third slot section 2C close to the door side wall 21. In the process of the door body 200 pivoting and opening, there is a stage in which the first axis 31 moves along the third slot section 2C, and in this stage, there is a stage in which the distance between the first axis 31 and the door side wall 21 decreases. In this way, the door side wall 21 at least generates a motion component close to the first axis 31 relative to the box body 100. When the first axis 31 is located on the side of the door side wall 21 away from the side environment member 400, the door side wall 21 or the door body 200 can be translated away from the side environment member 400 to prevent interference.

[0191] The side of the door side wall 21 at the door body 200 is defined as the pivot side, and the other side of the door body 200 opposite to the door side wall 21 is defined as the movable side (the movable side is farther away from the side environment member 400 relative to the pivot side when the door is closed). Through the above configuration, the interference between the pivot side and the side environment member 400 can be avoided to a great extent; as the pivot opening stage progresses, the first shaft 31 gradually approaches and finally cooperates with the limit block 81 located at the end of the third groove section 2C near the door side wall 21. At this time, the movable side or the door front wall 22 can be further prevented from interfering with the side environment member 400 by limiting the extreme angle of the pivot.

[0192] like Fig.10 As shown, when the pivot angle between the door body 200 and the box body 100 is a limiting angle, the hinge shaft cooperates with the limiting block 81. The limiting angle is one of 75 degrees to 120 degrees, and can be specifically 105 degrees.

[0193] like Figures 11 to 13 As shown, the stopper 81 includes a first side portion 811. The hinge shaft includes a first shaft 31, and the first shaft 31 is used to cooperate with the stopper 81. The first side portion 811 is close to the side of the first shaft 31 and is formed into a shape that matches the surface of the first shaft 31. In this way, it can fit the outer surface of the first shaft 31 to achieve full limit and reduce the strain on the first shaft 31.

[0194] In one embodiment, the stopper 81 further includes a second side portion 812. The hinge slot 2 includes a third slot section 2C for setting the stopper 81. The second side portion 812 has a second dimension d in the depth direction of the third slot section 2C, and the first side portion 811 has a first dimension D in the depth direction of the third slot section 2C. In one embodiment, the first dimension D is greater than the second dimension d, so as to increase the structural strength of the side that cooperates with the first shaft 31 by increasing the dimension.

[0195] In one embodiment, the limit block 81 also includes a plurality of reinforcing ribs 813 connected from the first side portion 811 to other parts of the limit block 81. In one embodiment, the plurality of reinforcing ribs 813 extend from the first side portion 811 in a direction close to the second side portion 812 to enhance the structural strength in a direction from the first side portion 811 to the second side portion 812 to prevent the collision of hinge axes such as the first axis 31 from causing the limit block 81 to be dislocated or strained. In one embodiment, the reinforcing ribs 813 bulge from the surface of the groove wall of the limit block 81 away from the hinge groove 2 in a direction away from the groove wall of the hinge groove 2; when the first side portion 811 and the second side portion 812 are configured to have a size difference, the bulge height of the reinforcing ribs 813 does not exceed the first side portion 811 to balance the structural strength and the space occupied by the limit block 81.

[0196] For the above groove wall, when the stopper 81 is fixed inside the hinge groove 2 through the groove bottom of the hinge groove 2, the reinforcing rib 813 bulges away from the groove bottom. When the stopper 81 is fixed inside the hinge groove 2 through the groove side wall of the hinge groove 2, the reinforcing rib 813 bulges away from the groove side wall.

[0197] The groove wall of the hinge groove 2 is provided with a fixing hole 80; the explanation of the groove wall is the same as above, and it can be the groove bottom or the groove side wall. The limit block 81 is detachably connected to the hinge groove 2 through a fastener 82 that cooperates with the fixing hole 80. In one embodiment, the fastener 82 is provided on the opening side of the hinge groove 2; the main part of the fastener 82 is provided on the side of the limit block 81 away from the fixing hole 80. During disassembly and assembly, the fastener 82 can be matched with the fixing hole 80 from the opening side of the hinge groove 2. Even in the scenario where the storage component is fully assembled, the limit block 81 can be conveniently disassembled and assembled.

[0198] In one embodiment, a plurality of fixing holes 80 are arranged at intervals along the extension direction of at least part of the hinge groove 2; in one embodiment, a plurality of fixing holes 80 are arranged at intervals in the third groove section 2C for cooperation with the first shaft 31; in other embodiments, a plurality of fixing holes 80 can also be arranged at intervals in the first groove section 2A for cooperation with the first shaft 31, and / or arranged at intervals in the second groove section 2B for cooperation with the second shaft 32 or the first shaft 31.

[0199] In one embodiment, a plurality of fixing holes 80 are arranged at intervals at the bottom of at least one of the above-mentioned groove sections to facilitate the disassembly and assembly of the limit block 81 .

[0200] In one embodiment, the fastener 82 cooperates with at least one of the plurality of fixing holes 80 to fix the limit block 81 at a corresponding position in the hinge slot 2. In other words, by cooperating and disengaging the fastener 82 from the fixing hole 80, the limit block 81 can be switched between different fixing holes 80, thereby achieving position adjustment of the limit block 81 in the extending direction of the slot section.

[0201] In one embodiment, the stopper 81 includes a first side portion 811 and a through hole 810. The first side portion 811 is used to cooperate with the hinge shaft, and can be used to cooperate with the first shaft 31. The through hole 810 is provided on the side of the stopper 81 away from the first side portion 811 to limit the position of the first side portion 811 in the hinge slot 2 from the other side. The fastener 82 passes through the through hole 810 and the fixing hole 80 to fix the stopper 81 to the hinge slot.

[0202] When the fastener 82 is disposed on one side of the groove bottom, the fastener 82 sequentially passes through the fixing hole 80 and the through hole 810. When the fastener 82 is disposed on one side of the groove opening, the fastener 82 sequentially passes through the through hole 810 and the fixing hole 80.

[0203] When the hinge shaft cooperates with the first side portion 811 or even squeezes the first side portion 811 due to a collision, the through hole 810 and the fastener 82 are disposed at a relatively far distance, thereby preventing the hinge shaft and the first side portion 811 from further interfering with the fastener 82 and causing damage.

[0204] The stopper 81 includes a second side portion 812, and the hinge slot 2 includes a third slot section 2C for setting the stopper 81. The second side portion 812 is close to the side of the slot wall of the third slot section 2C and is formed into a shape matching the slot wall of the third slot section 2C.

[0205] In one embodiment, the ends of the limit blocks 81 are configured to be arc-shaped.

[0206] In one embodiment, the limit block 81 is configured to be a metal material or a plastic material with good mechanical properties.

[0207] The hinge axis includes a first axis 31 and a second axis 32. The hinge slot 2 includes a second slot segment 2B and a third slot segment 2C connected at their heads; the second slot segment 2B and the third slot segment 2C extend in different directions.

[0208] During the pivoting of the door body 200 , relative to the door body 200 , there is a stage in which the first shaft 31 moves along the third slot segment 2C and the second shaft 32 is located in the second slot segment 2B.

[0209] The door body 200 includes a door side wall 21 that is adjacent to the side environment member 400 when the door is closed.

[0210] The door body 200 includes a door front wall 22 facing away from the box body 100 when the door is closed.

[0211] The following will specifically describe the relevant motion characteristics of the storage assembly provided by the present invention when the limiting block 81 is provided. The motion in the first slot section 2A not affected by the limiting block 81 will not be described in detail below and can be configured according to the embodiments provided above.

[0212] In one embodiment, if Figures 4 to 5 , Fig.10 and Fig.14 In the process of the door body 200 pivoting and opening from the second angle α2 to the third angle α3', the first shaft 31 moves from the second guide position P2 to the third guide position P3' of the third slot section 2C relative to the door body 200. The third guide position P3' is located on the side of the second guide position P2 away from the door side wall 21. The third guide position P3' is located on the side of the second guide position P2 away from the door front wall 22.

[0221] In one embodiment, the third track line 6C′ is an arc line, and the radius is equal to the distance between the first axis 31 and the second axis 32 .

[0222] Relative to the door body 200, when the second shaft 32 moves along one of the two groove sections, the center point of the shaft moves to form a trajectory line; for example, when the second shaft 32 moves in the second groove section 2B, the projection of the center point of the second shaft 32 or its center line on the bottom of the hinge groove 2 moves accordingly to form a second trajectory line 6B.

[0239] When the door body 200 pivots and opens from the first angle α1 to the second angle α2, the first shaft 31 moves from the first guide position P1 to the second guide position P2, and the second shaft 32 moves from the first driving position Q1 to the second driving position Q2 relative to the door body 200.

[0240] Based on this, in one embodiment, the distance between the first guide position P1 and the second guide position P2 is greater than the distance between the first axis 31 and the second axis 32 .

[0241] Based on this, in one embodiment, the second guide position P2 is located at a side of the first driving position Q1 close to the door side wall 21 ; the second guide position P2 is located at a side of the first driving position Q1 away from the door front wall 22 .

[0243] like Figure 1 and Fig.16 As shown, when the storage assembly includes a lower hinge assembly 500 , the above description of the hinge assembly 300 can be interpreted as a description of the upper hinge assembly; the above configuration of the hinge assembly 300 can be transferred to the lower hinge assembly 500 .

[0244] The lower hinge assembly 500 includes a lower slot mounting block 51 . The configuration of the lower slot mounting block 51 may be the same as or similar to the configuration of the slot mounting block 7 described above, and will not be described in detail herein.

[0245] The lower hinge assembly 500 includes a lower fixing plate 521 for fixing, a lower supporting plate 522 for setting two shafts, and a first lower shaft 531 and a second lower shaft 532 which are arranged on the lower supporting plate 522 and extend upward to cooperate with the lower groove mounting block 51 .

[0246] The lower fixing plate 521 and the lower supporting plate 522 are fixed perpendicularly to each other.

[0247] A boss structure 530 is formed at the position where the first lower shaft 531 and the second lower shaft 532 are connected to the lower support plate 522. The boss structure 530 is arranged along the circumference of the two shafts to increase the width of the shaft in the radial direction and improve the structural strength.

[0249] In summary, the storage assembly and the refrigerator having the same provided by the present invention are provided with a limit block in the hinge groove, and the cooperation between the limit block and the hinge shaft at least prevents the pivot angle between the door body or the box body from changing, such as preventing the pivot angle from continuing to increase, preventing the pivot angle from continuing to decrease, or maintaining the pivot angle at the current value, thereby achieving the limitation of the pivot freedom in at least one direction (one-way, such as the opening direction or the closing direction) of the door body in the open state, alleviating the need for additional control of the door body, and improving the convenience of operating the internal space of the storage assembly in at least this state. Since the pivot angle is prevented from changing, it is also possible to prevent the corners of the door body from interfering with the environmental parts, avoiding problems such as loud noises and damage. Since the limit block is detachably connected to the hinge groove, the moment of preventing the pivot angle from changing can be adjusted according to demand by changing the positional relationship between the limit block and the hinge shaft, which has extremely strong convenience and flexibility.
