Next, the specific working process of the hinge assembly 30 is introduced.

In this embodiment, the box body 10 includes an outer side surface 13 adjacent to the hinge assembly 30 and on the extension section of the rotation path of the door body 20. The door body 20 includes a front wall 21 away from the containing chamber S and is always sandwiched on the front wall 21 The side wall 22 between the accommodating chamber S and the front wall 21 has a side edge 23 between the front wall 21 and the side wall 22.

10-13, when the door 20 is in the closed state, the first switching member 401 and the second switching member 402 are relatively stationary, and the first upper free section 4131 and the first lower free section 4141 overlap to form a first free section S1 , The second upper free section 4151 and the second lower free section 4161 overlap 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 the end of the first section L1 away from the second section L2.

Specifically, the outer side surface 13 and the side wall 22 are located on the same plane, which can ensure the smoothness of the appearance, improve the aesthetics, and also facilitate the installation of the door body 20, but it is not limited to this.

14-17, when the door body 20 is in the process of opening from the closed state to the first intermediate opening angle α11, the first switching member 401 and the second switching member 402 are relatively stationary, and the first upper free section 4131 and the first upper free section 4131 are relatively static. The lower free section 4141 overlaps to form the first free section S1. The second upper free section 4151 and the second lower free section 4161 overlap to form the second free section S2. The second shaft 312 moves in the first section L1 to drive the first free section S1. The shaft body 311 moves from the initial position A1 to the stop position A2, and the door body 20 moves from the pivoting side P toward the containing chamber S.

Here, the side edge 23 moves to the side of the outer side surface 13 close to the receiving chamber S, that is, at this time, the hinge assembly 30 drives the side edge 23 to move to the side close to the receiving chamber S, and the door 20 is opened during the opening process. In this way, it is possible to avoid interference with surrounding cabinets or walls due to the side ribs 23 protruding from the outer side surface 13.

Here, in order to ensure the opening degree of the box body 10 as much as possible and avoid the problem that drawers, shelves, etc. in the box body 10 cannot be opened due to the interference of the door body 20, the side ribs 23 are moved to the side close to the accommodating chamber S to the outside. After the side surface 13 is in the plane, the hinge assembly 30 drives the side edge 23 to move in the plane and gradually approach the containing chamber S.

That is to say, at this time, on the basis of ensuring that the side edge 23 does not protrude from the corresponding outer side surface 13, the side edge 23 is made as close to the outer side surface 13 as possible. In this way, the door body 20 can be prevented from contacting the surrounding cabinets during the opening process. Or interference is caused by the wall, etc., and the opening of the box 10 can be ensured as much as possible.

With reference to Figures 18 to 21, when the door body 20 is in the process of continuing to open from the first intermediate opening angle α11 to the first opening angle α1, the first switching element 401 and the second switching element 402 are relatively stationary, and the first upper opening is free. The section 4131 coincides with the first lower free section 4141 to form a first free section S1, the second upper free section 4151 and the second lower free section 4161 coincide to form a second free section S2, and the second shaft 312 moves in the second section L2 The first shaft body 311 is driven to move from the stop position A2 toward the initial position A1, and the door body 20 moves from the containing chamber S toward the pivoting side P so that the side edge 23 is kept on the side of the outer side surface 13 close to the containing chamber S.

Here, the side edge 23 moves in the plane of the outer side surface 13 and gradually approaches the containing chamber S.

It is understandable that when the door body 20 is in the process of continuing to open from the second intermediate opening angle α12 to the first opening angle α1, if the door body 20 rotates in situ relative to the box body 10, the side edge 23 will gradually move closer to the receiving cavity. One side of the chamber S moves, and at the same time, the door body 20 gradually moves closer to the containing chamber S. The door body 20 will hinder the opening of the drawers, shelves, etc. in the box body 10, that is, the opening degree of the box body 10 will be reduced.

The hinge assembly 30 of this embodiment drives the side edges 24 to move in the plane where the outer side surface 13 is located, that is, the door body 20 can be kept as far away from the box body 10 as possible to ensure the opening of the box body 10 and avoid drawers and shelves in the box body 10. The problem that the object shelf and the like cannot be opened due to the interference of the door body 20 can also avoid the side edge 23 protruding out of the outer surface 13 in a direction away from the containing chamber S.

It should be noted that when the door 20 is opened from the closed state to the first opening angle α1, the fourth shaft 322 is always limited in the limiting section 4222 so that the switching assembly 40 limits the second hinge member 32.

In addition, in this process, since the first upper free section 4131 and the first lower free section 4141 always overlap into the first free section S1, the second upper free section 4151 and the second lower free section 4161 always overlap into the second free section. S2, that is, the trajectories of the first switching element 401 and the second switching element 402 are exactly the same, and the first shaft 311 moves in the first free section S1, and at the same time, the second shaft 312 moves in the second free section S2. During this process, the first switching element 401 and the second switching element 402 will never be staggered with each other, that is, the first switching element 401 and the second switching element 402 remain relatively stationary, which can avoid the first upper free section 4131 and the first lower free section 4141 are mutually misaligned, and at the same time, the second upper free section 4151 and the second lower free section 4161 are prevented from displacing each other. In this way, the smooth movement of the first shaft body 311 in the first free section S1 can be ensured, and the second shaft body 312 is free in the second free section. Section S2 moves smoothly.

With reference to Figures 22 to 25, when the door body 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the first switching element 401 and the second switching element 402 move relative to each other to make the fourth shaft body 322 is separated from the limiting section 4222, and the first shaft body 311 and/or the second shaft body 312 are limited in the

locking section

4132, 4142, 4152, 4162, so that the switching assembly 40 limits the first hinge member 31.

Here, "the first switching member 401 and the second switching member 402 move relative to each other so that the second hinge member 32 is disengaged from the limit of the switching assembly 40, and the first shaft body 311 and/or the second shaft body 312 are limited to the

locking section

4132, 4142, 4152, 4162 and the switch assembly 40 to limit the first hinge member 31" refers to the relative movement between the switch assembly 40 and the second hinge member 32 so that there is no between the switch assembly 40 and the second hinge member 32 Restricting each other, the relative movement between the switching assembly 40 and the first hinge part 31 causes the switching assembly 40 and the first hinge part 31 to be restricted to each other.

In this embodiment, the first shaft body 311 is confined to the first upper locking section 4132 and the first lower locking section 4142 at the same time, and the second shaft body 312 is confined to the second upper locking section 4152 and the second lower locking section at the same time. The stop section 4162, and the fourth shaft body 322 departs from the fourth limit section 4222, the description is as follows:

When the door body 20 is opened to the first opening angle α1, the second shaft 312 moves from the second free section S2 to the second lower locking section 4162 and is limited. At this time, the first shaft 311 and the second shaft 312 Can no longer move relative to the first free section S1 and the second free section S2, and at this time, the first shaft body 311 is adjacent to the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 is adjacent to the second The trajectories of the upper locking section 4152, the first upper locking section 4132 and the second upper locking section 4152 are adapted to the movement paths of the first shaft body 311 and the second shaft body 312.

When the door body 20 continues to open on the basis of the first opening angle α1, the door body 20 drives the second hinge member 32 connected to the door body 20 to move, and the second hinge member 32 passes through the third free section 4211 and the fourth limit section At 4222, a force is applied to the third shaft 321 and the fourth shaft 322, and then 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 body 311 is adjacent to the first upper locking section 4132, the second shaft body 312 is adjacent to the second upper locking section 4152, and the first switching member 401 can be opposed to the first shaft body 311 and the second shaft body. 312 moves by a first angle until the first shaft body 311 is confined to the first upper locking section 4132, and the second shaft body 312 is confined to the second upper locking section 4152, and at the same time, the second switching member 402 is positioned at the fifth shaft body 50 is the center of the circle and moves a second angle relative to the first shaft body 311 until the first shaft body 311 is confined within the second upper locking section 4152. In this process, the second shaft body 312 and the second lower locking section 4162 Always touch, the second angle is greater than the first angle.

That is to say, both the first switching element 401 and the second switching element 402 will rotate at a certain angle, and the rotation angle of the second switching element 402 is greater than the rotation angle of the first switching element 401, the first switching element 401 and the second switching element 401 Relative movement will also occur between 402 and they will be staggered with each other.

It is understandable that the rotation process of the first switching element 401 and the second switching element 402 does not have a certain sequence, and the two can be rotated at the same time. For example, the first switching element 401 and the second switching element 402 are in a certain sequence. Synchronously rotate within the range of the rotation angle, and then the first switching element 401 and the second switching element 402 are staggered with each other.

In actual operation, the first switching element 401 and the second switching element 402 drive the first groove body 411 and the second groove body 412 to rotate relative to the first shaft body 311 and the second shaft body 312, respectively, and the first shaft body 311 separates from the first shaft body 311 and the second shaft body 312. The free section S1 abuts the first upper locking section 4132 and the first lower locking section 4142, that is, the first shaft body 311 is confined to the first upper locking section 4132 and the first lower locking section 4142 at the same time, and the second The 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 confined to the second upper locking section 4152 and the second lower locking section at the same time. At the same time, the movement of the second switching member 402 causes the fourth shaft 322 to escape from the fourth limiting section 4222.

It can be understood that when the first shaft body 311 is located at the first upper locking section 4132 and the first lower locking section 4142, since the first switching element 401 and the second switching element 402 are mutually staggered, they are originally overlapped with each other. The first upper free section 4131 and the first lower free section 4141 will also be staggered. At this time, the first upper free section 4131 and the first lower free section 4141 are mutually staggered to restrict the first shaft body 311 from being separated from the first upper locking section 4132. And the first lower locking section 4142 can ensure that the first shaft body 311 is always maintained at the first upper locking section 4132 and the first lower locking section 4142 while the door body 20 continues to be opened.

Similarly, when the second shaft body 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 originally overlapping first The second upper free section 4151 and the second lower free section 4161 will also be staggered. At this time, the staggered second upper free section 4151 and the second lower free section 4161 restrict the second shaft 312 from separating from the second upper locking section 4152 and The second lower locking section 4162 can ensure that the second shaft 312 remains at the second upper locking section 4152 and the second lower locking section 4162 while the door 20 continues to be opened.

In addition, the rotation angle of the second switching element 402 is greater than the rotation angle of the first switching element 401, that is, the second switching element 402 and the first switching element 401 are staggered with each other, which can further improve the relationship between the first hinge element 31 and the switching assembly 40. The locking effect ensures that the first shaft 311 is always maintained at the first upper locking section 4132 and the first lower locking section 4142, and the second shaft 312 is always maintained at the second upper locking section 4152 and the first lower locking section 4142. The second locking section is at 4162.

At the same time, when the first switching element 401 and the second switching element 402 move relatively, the distance between the third shaft 321 on the first switching element 401 and the fourth shaft 322 on the second switching element 402 occurs. The third shaft body 321 is always located in the third free section 4211, and the fourth shaft body 322 moves from the fourth limit section 4222 to the fourth free section 4221, that is, the fourth shaft body 322 departs from the fourth limit section 4222 .

It should be noted that in this embodiment, the first upper locking section 4132 is the part of the first upper free section 4131 close to the initial position A1. When the door body 20 is opened to the first opening angle α1, the first shaft body 311 moves from the stop position A2 to the initial position A1 without reaching the initial position A1. When the door 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the first shaft body 311 moves to the initial position A1 (that is, move to the first upper locking section 4132), and at the same time, the second shaft 312 moves to the first lower locking section 4142. In this process, the door body 20 substantially continues to move from the receiving chamber S to the pivoting side P movement.

With reference to Figures 26 to 29, when the door body 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the first switching element 401 and the second switching element 402 are relatively stationary, and the third shaft 321 is at The third free section 421 moves, and the fourth shaft 322 moves on the fourth free section 4221.

Here, the range of the first opening angle α1 is approximately 80°-83°, the second opening angle α2 is approximately 90°, and the maximum opening angle α3 is greater than 90°, that is, the door body 20 is opened to 80°-83° During the process, the door body 20 first displaces in the first direction X to prevent the door body 20 from interfering with the surrounding cabinets or walls during the opening process, and the rear door body 20 displaces in the second direction Y to avoid the door body 20 The body 20 hinders the opening of the drawers, shelves, etc. in the box body 10, and finally reaches 80°～83°. After that, the switch assembly 40 moves while the door body 20 continues to open to 90°, so that the door body 20 is moved. The replacement of the rotating shaft continues to rotate, that is, after 90°, the door body 20 continues to rotate in situ relative to the box body 10 with the third shaft body 321 as the rotating shaft to further open the door body 20.

It can be understood that the angle is not limited to the above description.

It can be seen that this embodiment can effectively control the sequence switching of the first hinge member 31 and the second hinge member 32 through the unlocking and locking effects of the switching assembly 40 on the first hinge member 31 and the second hinge member 32, so that the door The body 20 can be stably opened.

It can be understood that when the door body 20 is in the closing process, that is, when the door body 20 starts to close from the maximum opening angle α3, the switching assembly 40 can also effectively control the sequence switching of the first hinge member 31 and the second hinge member 32, namely When the door body 20 is in the process of closing from the maximum opening angle α3 to the second opening angle α2, the third shaft body 321 moves in the third free section 4211, the fourth shaft body 322 moves in the fourth free section 4221, and switches The assembly 40 locks the first hinge member 31. When the door body 20 is in the process of closing from the second opening angle α2 to the first opening angle α1, the first switching member 401 and the second switching member 402 move relative to each other so that the first The hinge member 31 is disengaged from the limit of the switching assembly 40, and the fourth shaft 322 is limited in the fourth limit section 4222. The switching assembly 40 locks the second hinge member 32. When the door 20 is closed from the first opening angle α1 to In the process of fully 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 body 20 and the opening process of the door body 20 are in the opposite sequence. The unlocking and locking effects of the switching assembly 40 on the first hinge member 31 and the second hinge member 32 can effectively control the door. The switching sequence of the first hinge member 31 and the second hinge member 32 during the opening and closing of the body 20.

In this embodiment, the center of the first shaft body 311 and the side edges 23 are at a first distance, the center of the first shaft body 311 and the front wall 21 are at a second distance, and the center of the first shaft body 311 is The side walls 22 are at a third distance, the center of the third shaft 312 and the side edges 23 are at a fourth distance, the center of the third shaft 312 and the front wall 21 are at a fifth distance, and the third shaft is at a fifth distance. There is a sixth distance between the center of 312 and the side wall 22. When the door 20 is in the process of opening from the closed state to the first opening angle α1, the first distance, the second distance, and the third distance are all reduced first After the trend, it shows an increasing trend. When the door body 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the fourth distance, the fifth distance, and the sixth distance remain unchanged.

In addition, in this embodiment, the first shaft body 311 and the third shaft body 321 are staggered from each other, so that it can be applied to a scene where a built-in cabinet or a refrigerator 100 has a small space.

With reference to Fig. 30, a simple schematic diagram of the refrigerator 100 embedded in the cabinet 200 is taken as an example for description.

In this embodiment, the box body 10 includes an opening 102 and a front end surface 103 arranged around the opening 102. The box body 10 also includes a receiving chamber S and an outer side surface 13 adjacent to the hinge assembly 30 and on the extension of the rotation path of the door body 20. The door body 20 includes a front wall 21 away from the containing chamber S and a side wall 22 always sandwiched between the front wall 21 and the containing chamber S. A side edge 23 is provided between the front wall 21 and the side wall 22.

Here, when the door body 20 is in the closed state and is opened to the first opening angle α1, the door body 20 rotates about the first shaft body 311, and there is a first distance between the first shaft body 311 and the front end surface 103, When the door body 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the door body 20 rotates around the third shaft body 321, and there is a second shaft between the third shaft body 321 and the front end surface 103. The second distance is greater than the first distance. In this way, the maximum opening angle of the fully built-in refrigerator 100 can be greatly increased.

In addition, there is a third distance between the first shaft body 311 and the outer side surface 13. When the door body 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the third shaft body 321 and the outer side surface 13 There is a fourth distance between them, and the fourth distance is smaller than the third distance, which can further increase the opening degree of the box body 10.

The specific instructions are as follows:

In some movement tracks of the refrigerator 100, it can be considered that the door body 20 moves relative to the door body 20 with the first shaft body 311 and the third shaft body 321 as axes in sequence.

In this embodiment, the hinge assembly 30 further includes a second shaft body 312 matching the first shaft body 311 and a fourth shaft body 322 matching the third shaft body 321. To simplify the description, simply regard the door body 20 as the first The one shaft body 311 is used as the axis to rotate, and then the switching assembly 40 is switched to use the third shaft body 321 as the axis to rotate.

In actual operation, in order to improve the embedding effect, it is better to completely embed the refrigerator 100 into the cabinet 200. The refrigerator 100 is a freely embedded refrigerator, that is, the front end 201 of the cabinet 200 and the front wall 21 of the door 20 away from the cabinet 10 It is located on the same plane, or the front wall 21 of the door body 20 does not protrude from the front end 201 of the cabinet 200 at all.

In the prior art, all refrigerators are single-axis refrigerators, and a certain distance must be maintained between the rotation axis of the refrigerator and the side wall and front wall of the refrigerator. In this way, there can be enough space to satisfy foaming or other processes. The position of the rotation axis of the refrigerator is roughly at the position of the first shaft 311 in FIG. 30. In this case, after the single-axis refrigerator is embedded in the cabinet 200, the cabinet 200 is sandwiched between the front end 201 and the inner wall 202. 203 is arranged corresponding to the side edge 23 of the door body 20. When the door body 20 is opened, the side edge 23 will interfere with the door body 20 to limit the maximum opening angle of the door body 20. In order to ensure the normal opening of the door body 20, the prior art The usual method is to increase the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100. The gap roughly needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of the limited space.

With reference to Figure 30, the shaded area represents the door 20 in the closed state. When the door 20 is in the opening process, if the door 20 always rotates around the first shaft 311 (ie, prior art), refer to Figure 30 Dotted line door 20', because the first shaft 311 is close to the front end 103, that is, the first shaft 311 is away from the front end 201 of the cabinet 200 at this time. When the door 20' is opened to a certain angle, the corners 203 of the cabinet 200 will change It interferes with the door body 20' to limit the maximum opening angle of the door body 20'.

In this embodiment, the third shaft body 321 is located on the first switching member 401. During the opening of the door body 20, the switching assembly 40 moves relative to the first hinge member 31 and the second hinge member 32 to make the third shaft body 321 gradually moves away from the front end surface 103, that is, the third shaft body 321 gradually moves toward the front end 201 of the cabinet 200, that is, at this time, the entire door body 20 moves away from the box body 10, refer to the solid line in FIG. 30 The interference effect of the door 20 and the corners 203 of the cabinet 200 on the door 20 is greatly reduced, and the corners 203 of the cabinet 200 will interfere with each other when the door 20 is opened to a larger angle, thereby greatly increasing the maximum opening angle of the door 20.

That is to say, in this embodiment, the switch assembly 40 can make the late door 20 rotate around the third shaft 321 as the axis, and the maximum opening of the door 20 can be effectively increased on the premise that the refrigerator 100 is freely inserted into the cabinet 200. The angle, thereby facilitating the user to operate the refrigerator 100, can greatly improve the user experience.

Moreover, in this embodiment, there is no need to increase the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100, and a seamless connection between the refrigerator 100 and the cabinet 200 can be achieved, which greatly improves the embedding effect.

In addition, while the switching assembly 40 of this embodiment drives the third shaft 321 to gradually move toward the front end 201 of the cabinet 200, it also drives the third shaft 321 to gradually approach the inner wall 202 of the cabinet 200, that is, when When the door body 20 rotates with the third shaft body 321 as the axis, the third shaft body 321 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first shaft body 311 at this time. In this way, the door body 20 can be improved. The maximum opening angle can make the door 20 far away from the box body 10 to increase the opening degree of the box body 10, which facilitates the opening and closing of shelves, drawers, etc. in the box body 10, or in other words, facilitates the picking and placing of items.

Of course, the third shaft body 321 ultimately serving as the rotating shaft can also be located in other positions. For example, when the door body 20 rotates around the third shaft body 321, the third shaft body 321 at this time is compared with the first shaft. The body 311 is close to the front end 201 of the cabinet 200, 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 of the door body 20, which can effectively prevent the door body 20 from interfering with the cabinet 200 during the opening and closing process.

In addition, it should be noted that the specific shaft groove design can effectively control the movement trajectory of the door 20. In this embodiment, the box 10 includes the pivot side P connected to the hinge assembly 30. When the door 20 is in the During the opening process, the hinge assembly 30 at least drives the door body 20 to move from the pivoting side P toward the accommodating chamber S, so as to prevent the door body 20 from interfering with the surrounding cabinets or walls during the opening process. The specific design can refer to the following implementation.

In this embodiment, the structure of the hinge assembly 30 located in different areas of the door body 20 will be different. The above-mentioned hinge assembly 30 is the hinge assembly 30 located between the upper part of the door body 20 and the box body 10. Below, in conjunction with FIGS. 31 and 32 , A brief introduction to the hinge assembly 30' located below the door body 20 and the box body 10.

The difference between the lower hinge assembly 30' and the upper hinge assembly 30 is that the first hinge part 31' of the lower hinge assembly 30' has a convex portion 313', and the second hinge part 32' has a corresponding hook 323', The hook 323' is an elastic member. When the door body 20 is in the closed state, the convex portion 313' acts on the hook 323' to deform to make the door body 20 and the box body 10 closely fit. When the door body 20 is in the opening process, The door body 20 drives the hook 323' to move, and the hook 323' is deformed and detaches from the convex portion 313'.

In other words, when the door body 20 is in the closed state, there is an interference fit between the convex portion 313' and the hook 323', which enhances the closing effect of the door body 20.

It should be noted that, since the switching assembly 40' is connected between the first hinge part 31' and the second hinge part 32', the second hinge part 32' also includes an extension 324' that passes through the switching assembly 40' in the thickness direction, The extension section 324' is connected to the hook 323', so that the hook 323' is arranged horizontally and can be matched with the convex portion 313'.

36, the hinge assembly 30a further includes a first riveting piece 4111a, a second riveting piece 4121a, a fifth shaft body 50a (including a riveting post 51a and a riveting post gasket 52a), a first through hole 4014a, and a second through hole 4024a , Through hole 4026a, the first switching member 401a includes a first lining 4011a, a first sliding plate 4012a, and a first bushing 4013a that are sequentially stacked, and the second switching member 402a includes a second lining 4021a, a first Two sliding pieces 4022a and a second bushing 4023a. The first switching member 401a also includes a first decorative piece 4015a covering the peripheries of the first sliding piece 4011a, the first sliding piece 4012a and the first bushing 4013a, and the second switching piece 402a It also includes a second decorative sheet 4025a covering the periphery of the second lining 4021a, the second sliding sheet 4022a, and the second bushing 4023a. The specific description of these components of the hinge assembly 30a can refer to the description of the first embodiment. No longer.

Next, the specific working process of the hinge assembly 30a is introduced.

In this embodiment, the box body 10a includes an outer side surface 13a adjacent to the hinge assembly 30a and on the extension section of the rotation path of the door body 20a. The door body 20a includes a front wall 21a away from the containing chamber S and always sandwiched on the front wall 21a. The side wall 22a between the accommodating chamber S and the front wall 21a has a side edge 23a between the front wall 21a and the side wall 22a.

37 to 40, when the door 20a is in the closed state, the first switching member 401a and the second switching member 402a are relatively stationary, and the first upper free section 4131a and the first lower free section 4141a overlap to form a first free section S1 , The second upper free section 4151a and the second lower free section 4161a overlap to form a second free section S2, the first shaft body 311a is located at the initial position A1, and the second shaft body 312a is located at one end of the second free section S2.

Specifically, the outer side surface 13a and the side wall 22a are located on the same plane, which can ensure the smoothness of the appearance, improve the aesthetics, and also facilitate the installation of the door body 20a, but it is not limited to this.

41 to 44, when the door body 20a is in the process of opening from the closed state to the first opening angle α1, the first switching member 401a and the second switching member 402a are relatively stationary, and the first upper free section 4131a and the first The lower free section 4141a overlaps to form a first free section S1. The second upper free section 4151a and the second lower free section 4161a overlap to form a second free section S2. The second shaft 312a moves in the second free section S2 to drive the first free section S2. The shaft body 311a moves from the initial position A1 to the stop position A2, and the door body 20a moves from the pivoting side P toward the accommodation chamber S.

Here, the side edge 23a moves to the side of the outer side 13a close to the accommodating chamber S, that is, at this time, the hinge assembly 30a drives the side edge 23a to move toward the side close to the accommodating chamber S, and the door body 20a is opened during the opening process. In this way, it is possible to avoid interference with surrounding cabinets or walls due to the side ribs 23a protruding from the outer surface 13a.

Here, in order to ensure the opening of the box 10a as much as possible and avoid the problem that drawers, shelves, etc. in the box 10a cannot be opened due to the interference of the door 20a, the side ribs 23a move to the side close to the accommodating chamber S to the outside. After the side surface 13a is in the plane, the hinge assembly 30a drives the side edge 23a to move in the plane and gradually approach the containing chamber S.

That is to say, at this time, on the basis of ensuring that the side rib 23a does not protrude from the corresponding outer side 13a, the side rib 23a is made as close to the outer side 13a as possible. In this way, it is possible to prevent the door body 20a from contacting the surrounding cabinets during the opening process. Or the wall may interfere, and the opening of the box 10a can be ensured as much as possible.

It should be noted that when the door body 20a is opened from the closed state to the first opening angle α1, the fourth shaft body 322a is always limited at the limiting section 4222a so that the switching assembly 40a limits the second hinge member 32a.

In addition, in this process, since the first upper free section 4131a and the first lower free section 4141a always overlap into the first free section S1, the second upper free section 4151a and the second lower free section 4161a always overlap into the second free section. S2, that is, the trajectories of the first switching element 401a and the second switching element 402a are exactly the same, and the first shaft 311a moves in the first free section S1, and at the same time, the second shaft 312a moves in the second free section S2. During this process, the first switching element 401a and the second switching element 402a will not be staggered with each other, that is, the first switching element 401a and the second switching element 402a remain relatively static, which can avoid the first upper free section 4131a and the first lower free section 4141a is misaligned with each other, and at the same time, the second upper free section 4151a and the second lower free section 4161a are prevented from misaligning each other. In this way, it can be ensured that the first shaft body 311a moves smoothly in the first free section S1, and the second shaft body 312a is free in the second free section. Section S2 moves smoothly.

With reference to FIGS. 45 to 48, when the door body 20a is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the first switching member 401a and the second switching member 402a move relative to each other to make the fourth shaft body 322a is separated from the limiting section 4222a, and the first shaft body 311a and/or the second shaft body 312a is limited to the

locking sections

4132a, 4142a, 4152a, 4162a, so that the switching assembly 40a limits the first hinge member 31a.

Here, "the relative movement of the first switching element 401a and the second switching element 402a causes the second hinge element 32a to escape the limit of the switching assembly 40a, and the first shaft body 311a and/or the second shaft body 312a are limited to the

locking section

4132a, 4142a, 4152a, 4162a so that the switch assembly 40a limits the first hinge part 31a" refers to the relative movement between the switch assembly 40a and the second hinge part 32a so that there is no between the switch assembly 40a and the second hinge part 32a. To limit each other, the relative movement between the switching assembly 40a and the first hinge part 31a causes the switching assembly 40a and the first hinge part 31a to limit each other.

In this embodiment, the first shaft body 311a is confined to the first upper locking section 4132a and the first lower locking section 4142a at the same time, and the second shaft body 312a is confined to the second upper locking section 4152a and the second lower locking section at the same time. The stop section 4162a, and the fourth shaft body 322a is separated from the fourth limit section 4222a, the description is as follows:

When the door body 20a is opened to the first opening angle α1, the second shaft body 312a moves from the second free section S2 to the second lower locking section 4162a and is restricted. At this time, the first shaft body 311a and the second shaft body 312a Can no longer move relative to the first free section S1 and the second free section S2, and at this time, the first shaft body 311a is adjacent to the first upper locking section 4132a and the first lower locking section 4142a, and the second shaft body 312a is adjacent to the second The trajectories of the upper locking section 4152a, the first upper locking section 4132a and the second upper locking section 4152a are adapted to the movement paths of the first shaft body 311a and the second shaft body 312a.

When the door body 20a continues to open on the basis of the first opening angle α1, the door body 20a drives the second hinge member 32a connected to the door body 20a to move, and the second hinge member 32a passes through the third free section 4211a and the fourth limit section 4222a applies force to the third shaft 321a and the fourth shaft 322a, and then the third shaft 321a and the fourth shaft 322a drive the first switching element 401a and the second switching element 402a to move.

Specifically, at this time, the first shaft body 311a is adjacent to the first upper locking section 4132a, the second shaft body 312a is adjacent to the second upper locking section 4152a, and the first switching member 401a can be opposed to the first shaft body 311a and the second shaft body. 312a moves at a first angle until the first shaft body 311a is confined to the first upper locking section 4132a, and the second shaft body 312a is confined to the second upper locking section 4152a, and at the same time, the second switching member 402a uses the fifth shaft body 50a is the center of the circle and moves a second angle relative to the first shaft 311a until the first shaft 311a is confined within the second locking section 4152a. During this process, the second shaft 312a and the second lower locking section 4162a are always Contact, the second angle is greater than the first angle.

That is, both the first switching element 401a and the second switching element 402a will rotate at a certain angle, and the rotation angle of the second switching element 402a is greater than the rotation angle of the first switching element 401a, the first switching element 401a and the second switching element 401a 402a will also move relative to each other and stagger each other.

It is understandable that the rotation process of the first switching element 401a and the second switching element 402a does not have a certain sequence, and the two can be rotated at the same time. For example, the first switching element 401a and the second switching element 402a are in a certain Synchronously rotate within the range of the rotation angle, and then the first switching element 401a and the second switching element 402a are staggered from each other.

In actual operation, the first switching element 401a and the second switching element 402a drive the first groove body 411a and the second groove body 412a to rotate relative to the first shaft body 311a and the second shaft body 312a, respectively, and the first shaft body 311a separates from the first shaft body 311a. The free section S1 is in contact with the first upper locking section 4132a and the first lower locking section 4142a, that is, the first shaft body 311a is confined to the first upper locking section 4132a and the first lower locking section 4142a at the same time, and the second The shaft 312a is separated from the second free section S2 and abuts on the second upper locking section 4152a and the second lower locking section 4162a, that is, the second shaft 312a is confined to the second upper locking section 4152a and the second lower locking section at the same time. At the same time, the movement of the second switching member 402a causes the fourth shaft 322a to escape from the fourth limiting section 4222a.

It can be understood that when the first shaft body 311a is located at the first upper locking section 4132a and the first lower locking section 4142a, the first switching element 401a and the second switching element 402a are mutually staggered, and originally overlapped with each other. The first upper free section 4131a and the first lower free section 4141a will also be staggered. At this time, the first upper free section 4131a and the first lower free section 4141a are mutually staggered to restrict the first shaft body 311a from leaving the first upper locking section 4132a. And the first lower locking section 4142a can ensure that the first shaft body 311a is always maintained at the first upper locking section 4132a and the first lower locking section 4142a while the door body 20a continues to be opened.

Similarly, when the second shaft 312a is located at the second upper locking section 4152a and the second lower locking section 4162a, since the first switching element 401a and the second switching element 402a are mutually staggered, the originally overlapping first The second upper free section 4151a and the second lower free section 4161a will also be staggered. At this time, the second upper free section 4151a and the second lower free section 4161a are mutually staggered to restrict the second shaft 312a from separating from the second upper locking section 4152a and The second lower locking section 4162a can ensure that the second shaft 312a is always maintained at the second upper locking section 4152a and the second lower locking section 4162a while the door 20a continues to be opened.

In addition, the rotation angle of the second switching element 402a is greater than the rotation angle of the first switching element 401a, that is, the second switching element 402a and the first switching element 401a are staggered with each other, which can further improve the relationship between the first hinge element 31a and the switching assembly 40a. The locking effect ensures that the first shaft body 311a is always maintained at the first upper locking section 4132a and the first lower locking section 4142a, and the second shaft body 312a is always maintained at the second upper locking section 4152a and the second upper locking section 4142a. At the second locking section 4162a.

At the same time, when the first switching element 401a and the second switching element 402a move relatively, the distance between the third shaft 321a located on the first switching element 401a and the fourth shaft 322a located on the second switching element 402a occurs. The third shaft body 321a is always located in the third free section 4211a, and the fourth shaft body 322a moves from the fourth limit section 4222a to the fourth free section 4221a, that is, the fourth shaft body 322a leaves the fourth limit section 4222a .

With reference to Figures 49 to 52, when the door body 20a is in the process of continuing to open from the second opening angle α2 to the second intermediate opening angle α21, the first switching member 401a and the second switching member 402a are relatively stationary, and the fourth shaft body 322a moves in the moving section M1 to drive the third shaft 321a to move from the starting position B1 to the pivoting position B2. The door moves from the containing chamber S to the pivoting side P so that the side edge 23a is kept on the outer surface 13a close to the containing One side of chamber S.

It should be noted that in this embodiment, the line connecting the starting position B1 and the pivoting position B2 is parallel to the moving section M1, that is, at this time, the door body 20a may not rotate but only translate, but not With this limitation, in other embodiments, the door body 20a may also move away from the box body 10a while rotating.

It is understandable that when the door body 20a is in the process of continuing to open from the second opening angle α2 to the second intermediate opening angle α21, if the door body 20a rotates in situ relative to the box body 10a, the side edge 23a will gradually move closer to the receiving cavity. One side of the chamber S moves, and at the same time, the door body 20a gradually moves closer to the containing chamber S. The door body 20a will obstruct the opening of the drawers, shelves, etc. in the box body 10a, that is, reduce the opening degree of the box body 10a.

The hinge assembly 30a of this embodiment can move the door body 20a as far away from the box body 10a as possible through the translation of the door body 20a, ensuring the opening of the box body 10a, and avoiding the drawers and shelves in the box body 10a from being interfered by the door body 20a. The problem of inability to open can also prevent the side edge 23a from protruding out of the outer surface 13a in a direction away from the containing chamber S.

With reference to Figures 53 to 56, when the door body 20a is in the process of continuing to open from the second intermediate opening angle α21 to the maximum opening angle α3, the first switching element 401a and the second switching element 402a are relatively stationary, and the third shaft body 321a Keeping at the pivoting position B2, the fourth shaft 322a moves in the rotating section M2 with the third shaft 321a as the center, and the door 20a continues to rotate in situ relative to the box 10a.

Here, the range of the first opening angle α1 is approximately 80°-83°, the second opening angle α2 is approximately 90°, and the maximum opening angle α3 is greater than 90°, that is, the door body 20a opens to 80°-83° During the process, the door body 20a is first displaced in the first direction X to avoid interference between the door body 20a and the surrounding cabinets or walls during the opening process, and finally reaches 80°～83°. After that, the door body 20a continues In the process of opening to 90°, the switch assembly 40a moves to make the door body 20a replace the rotating shaft and continue to rotate, that is, the door body 20a is displaced in the second direction Y after 90°, so as to prevent the door body 20a from obstructing the inside of the box body 10a. The drawers, shelves, etc. are opened, and the rear door body 20a uses the third shaft body 321a as a rotation axis to continue to rotate in situ relative to the box body 10a to further open the door body 20a.

It can be understood that the angle is not limited to the above description.

It can be seen that this embodiment can effectively control the sequence switching of the first hinge part 31a and the second hinge part 32a through the unlocking and locking effect of the switching assembly 40a on the first hinge part 31a and the second hinge part 32a, so that the door The body 20a can be stably opened.

It can be understood that when the door body 20a is in the process of closing, that is, when the door body 20a starts to close from the maximum opening angle α3, the switching assembly 40a can also effectively control the sequence switching of the first hinge member 31a and the second hinge member 32a, namely When the door 20a is in the process of closing from the maximum opening angle α3 to the second opening angle α2, the third shaft 321a moves in the third free section 4211a, and the fourth shaft 322a moves in the fourth free section 4221a, and switches The assembly 40a locks the first hinge member 31a. When the door body 20a is in the process of closing from the second opening angle α2 to the first opening angle α1, the first switching member 401a and the second switching member 402a move relative to each other so that the first The hinge member 31a is out of the limit of the switching assembly 40a, and the fourth shaft body 322a is limited to the fourth limit section 4222a. The switching assembly 40a locks the second hinge member 32a. When the door body 20a is closed from the first opening angle α1 to In the process of being completely closed, the first shaft body 311a moves in the first free section S1, and the second shaft body 312a moves in the second free section S2.

In other words, the closing process of the door body 20a and the opening process of the door body 20a are in the opposite sequence. The unlocking and locking functions of the first hinge member 31a and the second hinge member 32a by the switching assembly 40a can effectively control the door. The switching sequence of the first hinge part 31a and the second hinge part 32a during the opening and closing of the body 20a.

In this embodiment, the center of the first shaft body 311a and the side edges 23a are at a first distance, the center of the first shaft body 311a and the front wall 21a are at a second distance, and the center of the first shaft body 311a is There is a third distance between the side walls 22a. When the door body 20a is opened from the closed state to the first opening angle α1, the first distance, the second distance, and the third distance all show a decreasing trend.

In addition, there is a fourth distance between the center of the third shaft 312a and the side edges 23a, the fifth distance between the center of the third shaft 312a and the front wall 21a, and the distance between the center of the third shaft 312a and the side wall 22a The interval is the sixth interval. When the door body 20a is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the fourth interval, the fifth interval and the sixth interval all increase first and then remain unchanged .

It should be noted that the distance change is not limited to the above description. For example, when the door body 20a is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the fifth distance always remains unchanged, and the fourth The distance and the sixth distance both increase first and then remain unchanged, and so on.

In addition, in this embodiment, the first shaft body 311a and the third shaft body 321a are staggered from each other, so that it can be applied to a scene where a built-in cabinet or a space for accommodating the refrigerator 100a is small.

For other descriptions of this embodiment, reference may be made to the previous embodiment, which will not be repeated here.

In this embodiment, with reference to FIGS. 57 to 60, the refrigerator 100 is a refrigerator 100 with a wiring module 60.

The wiring module 60 includes a fixed end 61 and a free end 62 that are arranged oppositely. The fixed end 61 is connected to the door body 20. The free end 62 is movably arranged on the box body 10. The wiring E of the box body 10 passes through the free end 62 and the fixed end in turn. The end 61 extends to the door body 20.

Here, "the free end 62 is movably arranged on the box body 10" means that the free end 62 and the box body 10 are not fixed. As the door body 20 is opened, the free end 62 can move relative to the box body 10, so that the free end 62 can move relative to the box body 10. The wire E in the wire module 60 can also move freely as the door 20 is opened.

It should be noted that as the refrigerator 100 becomes more intelligent and multifunctional, some functional modules, such as an ice making module, a display module, etc., are usually provided on the door 20 of the refrigerator 100. These modules usually need to be connected to the The control module in the box 10 is connected. The wiring E of this embodiment extends to the door 20 through the wiring module 60, which can effectively avoid the phenomenon that the wiring E is pulled during the opening and closing process of the door 20, and can be adapted to The door body 20 with various motion trajectories, for example, when the hinge assembly 30 drives the door body 20 to move from the pivoting side P toward the accommodating chamber S, the extension trajectory of the wiring E will also change. In this embodiment, the wiring module 60 is used. The design can be fully adapted to this movement of the door body 20, and the extension track of the wiring E can be flexibly adjusted by the wiring module 60 to avoid wire jamming.

In this embodiment, the refrigerator 100 further includes a limiting space 101. The limiting space 101 includes a notch 1011 disposed toward the door body 20. The fixed end 61 of the cable routing module 60 passes through the notch 1011 to connect to the door body 20. When the door body 20 is in the process of opening, the door body 20 drives the wire routing module 60 to move in the limiting space 101, and the free end 62 is always located in the limiting space 101.

Here, the limiting space 101 is located at the top 11 of the box body 10, the wiring module 60 is arranged parallel to the top 11 of the box body 10, and the fixed end 61 is movably connected to the door body 20. Of course, the limiting space 101 can also be set in other areas .

Specifically, in this embodiment, the wiring module 60 includes a first housing 601 and a second housing 602. The second housing 602 is disposed adjacent to the top 11 of the box 10, and the first housing 601 is opposite to the second housing 602. 602 is away from the top 11 of the box 10, the first housing 601 and the second housing 602 cooperate with each other to form an accommodating cavity 603 for accommodating the wire E. The two ends of the accommodating cavity 603 are opened as a fixed end 61 and a free end 62.

The door body 20 protrudes upwards from the top 11 of the box body 10. The edge of the top 11 close to the door 20 is provided with a stop 111 protruding from the top 11, and the stop 111 is provided with a notch 1011. The refrigerator 100 includes a protrusion A plurality of protrusions 112 of the top portion 11 are formed, and the plurality of protrusions 112 are enclosed to form a limiting space 101.

Here, the first hinge member 31 is fixed at the edge position of the top 11, and in order to adapt to the design of the door body 20 protruding from the top 11, the first hinge member 31 of the hinge assembly 30 is roughly Z-shaped. Thus, the first hinge member 31 It can be extended from the top 11 of the box body 10 to the top of the door body 20 to be compatible with the switching assembly 40 on the top of the door body 20, and the plurality of protrusions 112 include a first hinge between the first hinge part 31 and the cable routing module 60. The protruding portion 1121 and the second protruding portion 1122 are spaced apart from the first protruding portion 1121. The first protruding portion 1121 can prevent the wiring module 60 from interfering with the first hinge member 31, and the outline of the first protruding portion 1121 and the wiring The movement trajectory of the module 60 is adapted, and the second protrusion 1122 may be a plurality of protrusions to reduce the collision between the wiring module 60 and the second protrusion 1122.

The refrigerator 100 may further include a cover body 103, which is located on the top 11 and covers the limiting space 101, the first hinge member 31, etc. The cover body 103 can be adapted to the stop 111, and the shape of the cover body 103 can be adjusted according to It depends on specific needs.

In addition, the fixed end 61 and the notch 1011 of the cable routing module 60 are located close to the hinge assembly 30. It can be understood that during the opening process of the door body 20, the cable routing module 60 will be exposed in the opening gap of the door body 20, and the fixed end 61 and the notch 1011 are arranged close to the hinge assembly 30. On the one hand, the movement trajectory of the wiring module 60 can be reasonably controlled, and on the other hand, it can prevent the wiring module 60 from affecting the appearance and normal use of the refrigerator 100.

The wiring module 60 is arranged horizontally and extends through the slot 1011 to the door body 20. The door body 20 is provided with a wiring hole H, and the wiring E extends from the fixed end 61 and extends from the wiring hole H to the door body 20 Inside, the area C adjacent to the wiring hole H is pivotally connected to the fixed end 61 area, and the door body 20 includes a cover 24 covering the fixed end 61, the wiring hole H and the area C. In this way, the wiring module 60 can be realized The movable connection with the door body 20, when the door body 20 is in the opening process, the door body 20 drives the wire routing module 60 to move, and the wire routing module 60 can move freely according to different trajectories in the limit space 101, that is, The movement trajectory of the wiring module 60 can be completely adapted to the movement trajectory of the door body 20, thereby avoiding wire jamming.

In addition, the wiring module 60 includes a circular arc segment D, which can further prevent the wiring E from being disturbed inside the receiving cavity 603.

It should be noted that, in order to avoid the wear and sliding noise of the wiring module 60, a buffer member or sliding member, etc. can be provided between the second housing 602 of the wiring module 60 and the top 11 of the box body 10, which may be based on actual conditions. It depends on the situation.
