When the door 20 is in the process of opening from the closed state to the first opening angle α 1 (refer to fig. 11 to 14), the second shaft 312 moves in the second free section S2 to drive the first shaft 311 to move from the initial position a1 to the stop position a2, and the door 20 moves away from the box 20 along the first direction X.
Here, when the door 20 is in the process of being opened from the closed state to the first opening angle α 1, the door 20 moves away from the cabinet 20 in the first direction X, that is, the door 20 moves toward the front end away from the cabinet 10, so that the door 20 and the cabinet 10 can be separated from each other by the hinge assembly 30, thereby improving the smoothness of opening the door.
When the door body 20 is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2 (refer to fig. 15 to 18), the fourth shaft body 322 is separated from the position-limiting section 4222, and the first shaft body 311 and/or the second shaft body 312 is limited by the locking sections 4132, 4142, 4152, 4162, so that the switching assembly 40 limits the first hinge member 31.
When the door 20 is in the process of continuously opening from the second opening angle α 2 to the maximum opening angle α 3 (refer to fig. 19 to fig. 22), the third shaft 321 rotates in situ in the third free section 421, the fourth shaft 322 moves in the fourth free section 4221 around the third shaft 321, and the door 20 continuously rotates in situ relative to the box 10.
In the present embodiment, the cabinet 10 further includes an outer side surface 13 adjacent to the hinge assembly 30 and on an extension of a rotation path of the door body 20, and a front end surface 103 disposed around the opening 102.
Here, the outer side surface 13 is a left side surface or a right side surface of the box body 10, different hinge assemblies 30 can correspond to different outer side surfaces 13, and the front end surface 103 is an end surface of the box body 10 close to the door body 20.
The door 20 includes a door body 25 and a door seal 26 connected together, and the door seal 26 includes a side door seal 261 adjacent to the outer side 13.
Here, the door seal 26 is annularly disposed on a side surface of the door body 25 close to the cabinet 10, and the side door seal 261 is a door seal disposed closest to the hinge assembly 30 and in a vertical direction.
When the door 20 is in the closed state, the door seal 26 and the front end surface 103 contact each other.
Here, the door seal 26 and the front end surface 103 contact each other to achieve a sealing engagement between the door 20 and the cabinet 10, and generally, the sealing effect is improved by the pressing, magnetic attraction, and the like of the door seal 26.
When the door body 20 is in the opening process, the distance between the side door seal 261 and the front end surface 103 is increased.
Here, in the opening process of the door body 20, the door body 20 moves away from the box 10 along the first direction X, the distance between the side door seal 261 and the front end surface 103 is increased, that is, the hinge assembly 30 can assist the door seal 26 to separate from the front end surface 103 of the box 10, so that the door body 20 can be prevented from being smoothly separated from the box 10 due to obstruction of the door seal 26 (for example, the door seal 26 is excessively extruded, the magnetic attraction force is excessively strong, and the like), and the user can open the door body 20 conveniently.
The refrigerator 100 of the present embodiment is not limited to be used to avoid the obstruction of the door seal 26, and may be used to obstruct the opening of the door 20 with other structures, for example, frost may be formed between the cabinet 10 and the door 20.
In the present embodiment, when the door body 20 is in the opening process, the hinge assembly 30 drives the door body 20 to move away from the cabinet 10 in the first direction X, and at the same time, the hinge assembly 30 drives the door body 20 to move toward the accommodation chamber S from the pivot side P.
Here, when the door 20 is in the opening process, the door 20 moves toward one side of the accommodating chamber S, that is, at this time, the door 20 rotates relative to the box 10 and also displaces relative to the box 10 along the second direction Y, so that the distance that the door 20 protrudes out of the box 10 toward the side away from the accommodating chamber S in the rotating process is greatly reduced, that is, the displacement generated by the door 20 along the second direction Y offsets the portion protruding out of the box 10 in the rotating process of the door 20, thereby preventing the door 20 from interfering with peripheral cabinets or walls and the like in the opening process, and being suitable for embedded cabinets or scenes with small space for accommodating the refrigerator 100.
In the opening process of the door 20 according to the present embodiment, the door 20 moves in the first direction X and the second direction Y simultaneously, so that the door 20 is opened smoothly, and the door 20 does not interfere with the surrounding cabinet or wall.

In the present embodiment, the first switching member 401 is closer to the first hinge member 31 than the second switching member 402, that is, the first hinge member 31, the first switching member 401, the second switching member 402, and the second hinge member 32 are stacked in this order.
Referring to fig. 6, the hinge assembly 30 further includes a first rivet tab 4111 and a second rivet tab 4121, when the first shaft 311 extends into the first slot 411, the first rivet tab 4111 is located below the second switch member 402 and is sleeved on the first shaft 311, so as to prevent the first shaft 311 from separating from the first slot 411, and similarly, when the second shaft 312 extends into the second slot 412, the second rivet tab 4121 is located below the second switch member 402 and is sleeved on the second shaft 312, so as to prevent the second shaft 312 from separating from the second slot 412.
The first switching member 401 and the second switching member 402 are coupled to each other through the fifth shaft 50.
Here, the first switch 401 and the second switch 402 are provided with a first through hole 4014 and a second through hole 4024, and an independent rivet is inserted as the fifth shaft body 50 through the first through hole 4014 and the second through hole 4024.

It should be noted that the first through hole 4014 and the second through hole 4024 are matched with the fifth shaft 50, and the first switch member 401 rotates in place relative to the second switch member 402.
In another embodiment, a through hole may be formed in one of the first switching member 401 and the second switching member 402, and the fifth shaft 50 is disposed in the other, so that the first switching member 401 and the second switching member 402 are coupled with each other by the engagement of the fifth shaft 50 and the through hole, but not limited thereto.

Here, the size of the through hole 4026 may be larger than that of the third shaft 321, such that the third shaft 321 can move in the through hole 4026, and when the first switching member 401 and the second switching member 402 move relatively, the through hole 4026 and the third shaft 321 can be prevented from interfering with each other.
That is, the third shaft 321 and the fourth shaft 322 are located in different switching elements in this embodiment, but the invention is not limited thereto.

Here, "the first decorative piece 4015 and the second decorative piece 4025 are separated from each other" means that the first decorative piece 4015 and the second decorative piece 4025 are independent from each other, and when the first switch 401 and the second switch 402 move relatively, the first decorative piece 4015 and the second decorative piece 4025 also move relatively.
In addition, the first decorative sheet 4015 of the present embodiment is shaped like a "door", that is, the first decorative sheet 4015 covers only three sides of the first switch 401, so as to facilitate the assembly of the first decorative sheet 4015, and the three sides can be provided with snap structures to realize the engagement with the first decorative sheet 4015, and the width of the first decorative sheet 4015 is substantially equal to the sum of the thicknesses of the first lining 4011, the first slide piece 4012, and the first bush 4013 in the stacking direction of the first switch 401 and the second switch 402.

The first decorative sheet 4015 and the second decorative sheet 4025 may be made of abs (acrylonitrile butadiene styrene) plastic.
Next, a specific operation flow of the hinge assembly 30 will be described.
In the present embodiment, the box 10 includes an outer side surface 13 adjacent to the hinge assembly 30 and on an extension of a rotation path of the door body 20, the door body 20 includes a front wall 21 far from the accommodating chamber S and a side wall 22 always interposed between the front wall 21 and the accommodating chamber S, and a side edge 23 is provided between the front wall 21 and the side wall 22.
Referring to fig. 7 to 10, when the door 20 is in the closed state, the first switching member 401 and the second switching member 402 are stationary relative to each other, the first upper free section 4131 and the first lower free section 4141 are overlapped to form a first free section S1, the second upper free section 4151 and the second lower free section 4161 are overlapped to form a second free section S2, the first shaft 311 is located at the initial position a1, and the second shaft 312 is located at one end of the second free section S2.
Specifically, the outer side surface 13 and the side wall 22 are located on the same plane, so that smoothness in appearance can be ensured, the appearance is more attractive, and the door body 20 can be conveniently mounted, but not limited thereto.
Referring to fig. 11 to 14, when the door 20 is in the process of opening from the closed state to the first opening angle α 1, the first switching member 401 and the second switching member 402 are relatively stationary, the first upper free segment 4131 and the first lower free segment 4141 are overlapped to form a first free segment S1, the second upper free segment 4151 and the second lower free segment 4161 are overlapped to form a second free segment S2, the second shaft 312 moves in the second free segment S2 to drive the first shaft 311 to move from the initial position a1 to the stop position a2, the door 20 moves away from the box 10 along the first direction X, the distance between the side door seal 261 and the front end surface 103 increases, and the door 20 moves from the pivot side P toward the accommodating chamber S.
In the prior art, because the hinge assembly is a single-shaft hinge assembly, the door body rotates in situ relative to the box body all the time, in actual operation, the axis position in the hinge assembly needs to be designed by considering factors such as the thickness of the door seal strip and the thickness of the door body, so that the door seal strip cannot obstruct the opening process of the door body, however, the design process of the axis position is complex, and the axis position cannot be kept at the predesigned position due to the influence of factors such as installation accuracy.
In this specific example, the door 20 moves in a direction away from the front end of the box 10 by the cooperation of the double shafts and the double grooves, so that the problem of blocking of the door seal 26 to the opening process of the door 20 can be effectively solved, high installation accuracy is not required, and the design cost and the installation difficulty can be greatly reduced.
In addition, it should be noted that when the door 20 is opened, the hinge assembly 30 drives the door 20 to move in a direction away from the front end of the box 10, so as to effectively assist the opening of the door 20, and at the same time, the hinge assembly 30 drives the door 20 to move from the pivot side P toward the accommodating chamber S, so as to prevent the door 20 from protruding out of the box 10.
It should be noted that, when the door body 20 is opened from the closed state to the first opening angle α 1, the fourth shaft body 322 is always limited by the limit section 4222, so that the switching assembly 40 limits the second hinge element 32.
In addition, in this process, since first upper free section 4131 and first lower free section 4141 are always recombined into first free section S1, second upper free section 4151 and second lower free section 4161 are always recombined into second free section S2, that is, the moving tracks of the first switching member 401 and the second switching member 402 are identical, and the first shaft 311 moves in the first free segment S1, and at the same time, the second shaft 312 moves in the second free segment S2, the first switching member 401 and the second switching member 402 are not always staggered from each other in this process, that is, the first switching member 401 and the second switching member 402 are kept stationary, the first upper free section 4131 and the first lower free section 4141 are prevented from being misaligned, while preventing the second upper free section 4151 and the second lower free section 4161 from being misaligned with each other, and thus, the first shaft 311 can move smoothly in the first free section S1, and the second shaft 312 can move smoothly in the second free section S2.
With reference to fig. 15 to 18, when the door 20 is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2, the first switching element 401 and the second switching element 402 move relatively to separate the fourth shaft 322 from the position-limiting section 4222, and the first shaft 311 and/or the second shaft 312 are/is limited by the locking sections 4132, 4142, 4152, 4162 to limit the first hinge 31 by the switching assembly 40.
Here, "the first switching element 401 and the second switching element 402 move relatively to separate the second hinge element 32 from the position of the switching component 40, and the first shaft 311 and/or the second shaft 312 are limited by the locking segments 4132, 4142, 4152, 4162 to limit the switching component 40 on the first hinge element 31" means that there is no mutual limit between the switching component 40 and the second hinge element 32 due to the relative movement between the switching component 40 and the second hinge element 32, and there is no mutual limit between the switching component 40 and the second hinge element 32 due to the relative movement between the switching component 40 and the first hinge element 31 to limit the switching component 40 and the first hinge element 31.
In the present embodiment, the first shaft 311 is simultaneously constrained by the first upper locking section 4132 and the first lower locking section 4142, the second shaft 312 is simultaneously constrained by the second upper locking section 4152 and the second lower locking section 4162, and the fourth shaft 322 is disengaged from the fourth constraining section 4222, as follows:
when the door 20 is opened to the first opening angle α 1, the second shaft 312 moves from the second free section S2 to the second lower locking section 4162 for limiting, at this time, the first shaft 311 and the second shaft 312 cannot move relative to the first free section S1 and the second free section S2 any more, and at this time, the first shaft 311 is adjacent to the first upper locking section 4132 and the first lower locking section 4142, the second shaft 312 is adjacent to the second upper locking section 4152, and the track of the first upper locking section 4132 and the track of the second upper locking section 4152 are adapted to the movement path of the first shaft 311 and the second shaft 312.
When the door 20 continues to be opened based on the first opening angle α 1, the door 20 drives the second hinge element 32 connected to the door 20 to move, the second hinge element 32 applies an acting force to the third shaft 321 and the fourth shaft 322 through the third free section 4211 and the fourth limiting section 4222, and the third shaft 321 and the fourth shaft 322 drive the first switching element 401 and the second switching element 402 to move.
Specifically, at this time, the first shaft 311 is adjacent to the first upper locking section 4132, the second shaft 312 is adjacent to the second upper locking section 4152, the first switching element 401 can move relative to the first shaft 311 and the second shaft 312 by a first angle until the first shaft 311 is limited by the first upper locking section 4132 and the second shaft 312 is limited by the second upper locking section 4152, and meanwhile, the second switching element 402 moves relative to the first shaft 311 by a second angle using the fifth shaft 50 as a center until the first shaft 311 is limited by the second upper locking section 4152, during this process, the second shaft 312 is always in contact with the second lower locking section 4162, and the second angle is greater than the first angle.
That is, the first switch 401 and the second switch 402 both rotate a certain angle, and the rotation angle of the second switch 402 is larger than that of the first switch 401, so that the first switch 401 and the second switch 402 move relative to each other and are staggered.
It can be understood that the rotation processes of the first switching member 401 and the second switching member 402 are not in a certain sequence, and the first switching member 401 and the second switching member 402 may rotate simultaneously, for example, the first switching member 401 and the second switching member 402 rotate synchronously within a certain rotation angle range, and then the first switching member 401 and the second switching member 402 are staggered.
In practical operation, the first switch element 401 and the second switch element 402 drive the first slot 411 and the second slot 412 to rotate relative to the first shaft 311 and the second shaft 312, respectively, the first shaft 311 is separated from the first free section S1 and abuts against the first upper locking section 4132 and the first lower locking section 4142, that is, the first shaft 311 is simultaneously limited at the first upper locking section 4132 and the first lower locking section 4142, the second shaft 312 is separated from the second free section S2 and abuts against the second upper locking section 4152 and the second lower locking section 4162, that is, the second shaft 312 is simultaneously limited at the second upper locking section 4152 and the second lower locking section 4162, and meanwhile, the movement of the second switch element 402 causes the fourth shaft 322 to be separated from the fourth limiting section 4222.
It can be understood that when the first shaft 311 is located at the first upper locking section 4132 and the first lower locking section 4142, since the first switching member 401 and the second switching member 402 are staggered, the first upper free section 4131 and the first lower free section 4141, which are originally overlapped with each other, are also staggered with each other, and at this time, the staggered first upper free section 4131 and the first lower free section 4141 limit the first shaft 311 from being separated from the first upper locking section 4132 and the first lower locking section 4142, so that the first shaft 311 can be ensured to be always kept at the first upper locking section 4132 and the first lower locking section 4142 in the process of continuously opening the door 20.
Similarly, when the second shaft 312 is located at the second upper locking section 4152 and the second lower locking section 4162, since the first switching member 401 and the second switching member 402 are staggered, the second upper free section 4151 and the second lower free section 4161, which are originally overlapped with each other, are also staggered, and at this time, the staggered second upper free section 4151 and the second lower free section 4161 limit the second shaft 312 from being separated from the second upper locking section 4152 and the second lower locking section 4162, so that the second shaft 312 is always kept at the second upper locking section 4152 and the second lower locking section 4162 in the process of continuously opening the door 20.
In addition, the rotation angle of the second switching member 402 is greater than that of the first switching member 401, that is, the second switching member 402 and the first switching member 401 are staggered from each other, so that the locking effect between the first hinge member 31 and the switching assembly 40 can be further improved, and it is ensured that the first shaft body 311 is always kept at the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 is always kept at the second upper locking section 4152 and the second lower locking section 4162.
Referring to fig. 19 to 22, when the door 20 is in the process of continuously opening from the second opening angle α 2 to the maximum opening angle α 3, the first switching member 401 and the second switching member 402 are stationary, the third shaft 321 moves in the third free segment 421, and the fourth shaft 322 moves in the fourth free segment 4221.
Here, the first opening angle α 1 is approximately 80 ° to 83 °, the second opening angle α 2 is approximately 90 °, and the maximum opening angle α 3 is greater than 90 °, that is, in a process that the door 20 is opened to 80 ° to 83 °, the door 20 is first displaced along the first direction X, so as to prevent the door 20 from interfering with a peripheral cabinet or wall during the opening process, and assist the door 20 to open, and finally reach 80 ° to 83 °, after that, in a process that the door 20 is continuously opened to 90 °, the switching assembly 40 moves to enable the door 20 to continue to rotate with the rotating shaft replaced, that is, after 90 °, the door 20 continues to rotate in situ with respect to the box 10 with the third shaft 321 as the rotating shaft, so as to further open the door 20.
It is to be understood that the angles are not limited by the above description.
It can be seen that, in the present embodiment, the switching assembly 40 unlocks and locks the first hinge member 31 and the second hinge member 32, so that the sequential switching of the first hinge member 31 and the second hinge member 32 can be effectively controlled, and the door body 20 can be stably opened.
It can be understood that, when the door 20 is in the closing process, that is, when the door 20 is closed from the maximum opening angle α 3, the switching component 40 can also effectively control the sequential switching of the first hinge component 31 and the second hinge component 32, that is, when the door 20 is in the process of closing from the maximum opening angle α 3 to the second opening angle α 2, the third shaft 321 moves in the third free section 4211, the fourth shaft 322 moves in the fourth free section 4221, and the switching component 40 locks the first hinge component 31, when the door 20 is in the process of closing from the second opening angle α 2 to the first opening angle α 1, the first switching component 401 and the second switching component 402 relatively move to make the first hinge component 31 separate from the limit of the switching component 40, and the fourth shaft 322 is limited in the fourth limit section 4222, the switching component 40 locks the second hinge component 32, when the door 20 is in the process of closing from the first opening angle α 1 to the complete closing, the first shaft 311 moves in the first free section S1, and the second shaft 312 moves in the second free section S2.
In other words, the closing process of the door 20 and the opening process of the door 20 are processes in reverse order, and the switching sequence of the first hinge member 31 and the second hinge member 32 in the opening and closing processes of the door 20 can be effectively controlled by the unlocking and locking actions of the switching assembly 40 on the first hinge member 31 and the second hinge member 32.
In the present embodiment, the initial position a1 is a smaller distance from the front wall 21 than the stop position a2, and the initial position a1 is a greater distance from the side wall 22 than the stop position a 2.
Specifically, the distance between the center of the first shaft body 311 at the initial position a1 and the front wall 21 is smaller than the distance between the center of the first shaft body 311 at the stop position a2 and the front wall 21.
The distance between the center of the first shaft body 311 at the initial position a1 and the side wall 22 is greater than the distance between the center of the first shaft body 311 at the stop position a2 and the side wall 22.
The first distance is formed between the center of the first shaft 311 and the front wall 21, the second distance is formed between the center of the first shaft 311 and the side wall 22, and the first distance and the second distance are changed when the door body 20 is opened.
When the door body 20 is in the process of opening from the closed state to the first opening angle α 1, the first distance is in an increasing trend, and the second distance is in a decreasing trend, and when the door body 20 is in the process of continuing to open from the second opening angle α 2 to the maximum opening angle α 3, both the first distance and the second distance are kept unchanged.
Here, when the door 20 is in the process of being opened from the closed state to the first opening angle α 1, the first distance tends to increase, i.e., the corresponding door 20 moves along the first direction X, and the second distance tends to decrease, i.e., the corresponding door 20 moves along the second direction Y.
In addition, in the present embodiment, the first shaft 311 and the third shaft 321 are offset from each other, and thus, the present invention is applicable to a built-in cabinet or a scene where a space for accommodating the refrigerator 100 is small.
Referring to fig. 23, a simple schematic diagram of the refrigerator 100 embedded in the cabinet 200 will be described.
In the present embodiment, the box 10 includes an opening 102 and a front end surface 103 disposed around the opening 102, the box 10 further includes an accommodating chamber S and an outer side surface 13 adjacent to the hinge assembly 30 and on an extension of a rotation path of the door 20, the door 20 includes a front wall 21 far from the accommodating chamber S and a side wall 22 interposed between the front wall 21 and the accommodating chamber S, and a side edge 23 is provided between the front wall 21 and the side wall 22.
Here, when the door 20 is in the process of being opened to the first opening angle α 1 in the closed state, the door 20 rotates around the first shaft 311, the first shaft 311 has a first distance from the front end surface 103, and when the door 20 is continuously opened from the second opening angle α 2 to the maximum opening angle α 3, the door 20 rotates around the third shaft 321, the third shaft 321 has a second distance from the front end surface 103, and the second distance is greater than the first distance, so that the maximum opening angle of the fully-embedded refrigerator 100 can be greatly increased.
In addition, a third distance is provided between the first shaft 311 and the outer side surface 13, and when the door 20 is in the process of being continuously opened from the second opening angle α 2 to the maximum opening angle α 3, a fourth distance is provided between the third shaft 321 and the outer side surface 13, and the fourth distance is smaller than the third distance, so that the opening degree of the box 10 can be further increased.
The concrete description is as follows:
in some movement tracks of the refrigerator 100, the first shaft 311 and the third shaft 321 move relative to the door 20, or the hinge assembly 30 further includes a second shaft 312 engaged with the first shaft 311 and a fourth shaft 322 engaged with the third shaft 321, for simplicity of description, it is simply regarded that the door 20 rotates with the first shaft 311 as a shaft first, and then is switched to rotate with the third shaft 321 as a shaft through the switching assembly 40.
In practice, in order to improve the insertion effect, it is preferable that the refrigerator 100 is completely inserted into the cabinet 200, and the refrigerator 100 is a free-insertion type refrigerator, that is, the front end 201 of the cabinet 200 is located on the same plane with the front wall 21 of the door 20 far from the cabinet 10, or the front wall 21 of the door 20 does not protrude out of the front end 201 of the cabinet 200 at all.
In the prior art, all refrigerators are single-shaft refrigerators, and a certain distance needs to be kept between a rotating shaft of the refrigerator and the side wall and the front wall of the refrigerator, so that enough space can be provided for satisfying foaming or other processes, that is, the position of the rotation shaft of the conventional refrigerator is approximately at the position of the first shaft body 311 in fig 23, in this case, after the single-axis refrigerator is inserted into the cabinet 200, since the corner 203 of the cabinet 200 between the front end 201 and the inner wall 202 is disposed corresponding to the side edge 23 of the door body 20, when the door 20 is opened, the side edge 23 interferes with the door 20 to limit the maximum opening angle of the door 20, in order to ensure the normal opening of the door 20, the conventional method is to increase the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100, this gap needs to be roughly around 10cm, which seriously affects the embedding effect and is not good for the rational use of limited space.
Referring to fig. 23, a shaded area represents the door 20 in a closed state, when the door 20 is in an opening process, if the door 20 always rotates around the first shaft 311 (i.e., in the prior art), referring to the dashed door 20 'in fig. 23, since the first shaft 311 is close to the front end surface 103, that is, the first shaft 311 is far away from the front end 201 of the cabinet 200, after the door 20' is opened to a certain angle, the edge 203 of the cabinet 200 interferes with the door 20 'to limit the maximum opening angle of the door 20'.
In the present embodiment, the third shaft 321 is located on the first switching element 401, and in the opening process of the door 20, the switching assembly 40 moves relative to the first hinge element 31 and the second hinge element 32 to make the third shaft 321 gradually away from the front end surface 103, that is, the third shaft 321 gradually moves toward the direction close to the front end 201 of the cabinet 200, that is, the whole door 20 moves toward the direction away from the box 10, referring to the solid-line door 20 in fig. 23, the interference effect of the corner 203 of the cabinet 200 on the door 20 is greatly reduced, and the corner 203 of the cabinet 200 interferes with each other when the door 20 is opened to a larger angle, so that the maximum opening angle of the door 20 is greatly increased.
That is to say, in the embodiment, the door 20 can rotate around the third shaft 321 through the switching component 40, so that the maximum opening angle of the door 20 can be effectively increased on the premise that the refrigerator 100 is freely embedded into the cabinet 200, the refrigerator 100 can be conveniently operated by a user, and the user experience can be greatly improved.
In addition, in the present embodiment, the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100 does not need to be increased, the refrigerator 100 and the cabinet 200 can be connected seamlessly, and the insertion effect is greatly improved.
In addition, the switching assembly 40 of the present embodiment drives the third shaft 321 to gradually move toward the front end 201 of the cabinet 200, and simultaneously drives the third shaft 321 to gradually approach the inner wall 202 of the cabinet 200, that is, when the door 20 rotates about the third shaft 321, the third shaft 321 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first shaft 311, so as to increase the maximum opening angle of the door 20, and further make the door 20 away from the cabinet 10 to increase the opening degree of the cabinet 10, thereby facilitating the opening and closing of the racks, drawers, etc. in the cabinet 10, or facilitating the taking and placing of articles.
Of course, the third shaft 321, which is finally used as a rotation shaft, may be located at other positions, for example, when the door 20 rotates around the third shaft 321, the third shaft 321 is closer to the front end 201 of the cabinet 200 than the first shaft 311, and the third shaft 321 is farther away from the inner wall 202 of the cabinet 200 than the first shaft 311.
It can be understood that, the switching assembly 40 controls the switching sequence of the first hinge member 31 and the second hinge member 32 during the opening and closing processes of the door 20, so as to effectively prevent the door 20 from interfering with the cabinet 200 during the opening and closing processes.
In addition, it should be noted that the motion trajectory of the door 20 can be effectively controlled through a specific design of the shaft body slot, in this embodiment, the box 10 includes a pivoting side P connected to the hinge assembly 30, when the door 20 is in the opening process, the hinge assembly 30 at least drives the door 20 to move from the pivoting side P toward the accommodating chamber S, so as to avoid the door 20 from interfering with a peripheral cabinet or wall in the opening process, and the following embodiments may be referred to for the specific design of the shaft body slot.
In the present embodiment, the hinge assembly 30 located at different regions of the door 20 has a different structure, and the hinge assembly 30 is a hinge assembly 30 located between the upper portion of the door 20 and the cabinet 10, and hereinafter, the hinge assembly 30' located between the lower portion of the door 20 and the cabinet 10 will be briefly described with reference to fig. 24.
The lower hinge assembly 30' differs from the upper hinge assembly 30 in that: the first hinge part 31 ' of the hinge assembly 30 ' has a protrusion 313 ', the second hinge part 32 ' has a corresponding hook 323 ', the hook 323 ' is an elastic part, when the door 20 is in a closed state, the protrusion 313 ' acts on the hook 323 ' to deform, so that the door 20 is tightly matched with the box 10, and when the door 20 is in an opening state, the door 20 drives the hook 323 ' to move, and the hook 323 ' deforms to separate from the protrusion 313 '.
That is, when the door 20 is in the closed state, the protruding portion 313 'and the hook 323' are in interference fit, so that the closing effect of the door 20 is enhanced.
It should be noted that, since the switching component 40 'is connected between the first hinge member 31' and the second hinge member 32 ', the second hinge member 32' further includes an extension 324 'passing through the switching component 40' in the thickness direction, and the extension 324 'is connected to the hook 323', so that the hook 323 'is horizontally disposed and can be matched with the protrusion 313'.
