[0030] It should also be noted that Figure 3 、 Figure 4 in the x direction is the movement direction of the locking structure 142, which is also the direction perpendicular to the first link 111, and at the same time is the length direction of the shelf, the y direction is the width direction of the shelf, and at the same time is the extension direction of the installation groove 151, the first chute 121, the second chute 131, the third chute 122 and the fourth chute 132, and the z direction is the direction perpendicular to the first shelf 12.
[0031] The present application provides a refrigerator, which includes an inner container 2 and a shelf assembly 1 disposed in the inner container 2. Figure 1 The inner container 2 and the shelf assembly 1 are shown in Figure 2As shown, it at least includes a first shelf 12 and a second shelf 13. The height between the first shelf 12 and the second shelf 13 can be controlled by a first connecting rod 111 and a second connecting rod 112 which are in transmission connection. When the shelf assembly 1 needs to hold more items, the first shelf 12 and the second shelf 13 are separated, so that both the first shelf 12 and the second shelf 13 can hold items, thereby improving the space utilization rate of the inner container 2. When there are smaller items, the smaller items require less storage space. Therefore, the distance between the first shelf 12 and the second shelf 13 can be adjusted according to the volume of the items, making the distance between the first shelf 12 and the second shelf 13 relatively small, so as to ensure that the smaller items can be placed on the second shelf 13. At this time, the first shelf 12 can hold larger items. The above settings can further improve the space utilization rate inside the inner container 2.
[0032] To ensure that the first shelf 12 and the second shelf 13 can move stably inside the inner container 2, the first connecting rod 111 and the second connecting rod 112 can be rotatably arranged in the inner container 2, so that the inner container 2 plays a supporting role on the first connecting rod 111 and the second connecting rod 112, and further ensures that the first connecting rod 111 and the second connecting rod 112 stably support the first shelf 12 and the second shelf 13.
[0033] This application provides a shelf assembly 1. The shelf assembly 1 can be arranged inside the above-mentioned refrigerator inner container 2. For the convenience of introduction, the following takes the shelf assembly 1 arranged inside the inner container 2 of the refrigerator as an example for introduction.
[0034] Such as Figure 2As shown in the figure, the shelf assembly 1 includes a connecting rod assembly 11 and a plurality of shelves. The connecting rod assembly 11 includes a first connecting rod 111 and a second connecting rod 112. The first end 111a of the first connecting rod 111 is drivingly connected to the first end 112a of the second connecting rod 112, so that the first connecting rod 111 is controlled to rotate and drive the second connecting rod 112 to rotate. The plurality of shelves includes a first shelf 12 and a second shelf 13. The second end 111b of the first connecting rod 111 is rotatably connected to the first shelf 12, and the second end 112b of the second connecting rod 112 is rotatably connected to the second shelf 13. The first connecting rod 111 is controlled to rotate, so that the first shelf 12 and the second shelf 13 approach or move away from each other along a direction perpendicular to the first shelf 12. By controlling the rotation of the first connecting rod 111, the first connecting rod 111 drives the second connecting rod 112 to rotate, so that the second connecting rod 112 rotates synchronously. When it is necessary to place items on multiple shelves, when the second end 111b of the first connecting rod 111 and the second end 112b of the second connecting rod 112 are controlled to rotate in a direction away from each other, the first shelf 12 and the second shelf 13 are respectively driven by the first connecting rod 111 and the second connecting rod 112 to move in a direction away from each other. At this time, the first shelf 12 and the second shelf 13 are separated, and both the first shelf 12 and the second shelf 13 can support items respectively. When the storage space in the refrigerator is sufficient and there is no need to place items on the extra shelves, the second end 111b of the first connecting rod 111 and the second end 112b of the second connecting rod 112 can be rotated in a direction close to each other. At this time, the first shelf 12 and the second shelf 13 gradually approach. When there is no storage space between the first shelf 12 and the second shelf 13, at this time, only the first shelf 12 can place items. By controlling the rotation angle of the first connecting rod 111, the rotation angle of the second connecting rod 112 can be further controlled, so as to realize the free adjustment of the distance between the first shelf 12 and the second shelf 13. The user can adjust the first shelf 12 and the second shelf 13 to an appropriate distance according to the needs or the volume of the items to be placed, so as to effectively allocate the storage space in the inner container 2 and make full use of the space of the inner container 2.
[0035] It should be noted that the number of shelves is not restrictive and can be set according to the needs of those skilled in the art. For example, the plurality of shelves may include not only the first shelf 12 and the second shelf 13, but also a third shelf and more shelves. Taking the example that the plurality of shelves further includes a third shelf and the second shelf 13 is located between the first shelf 12 and the third shelf, at this time, the connection manner between the second shelf 13 and the third shelf is the same as that between the first shelf 12 and the second shelf 13, and details will not be described here one by one.
[0036] In one embodiment, as Figure 3As shown, the connecting rod assembly 11 further includes a third connecting rod 113 and a fourth connecting rod 114. The first end 113a of the third connecting rod 113 is drivingly connected to the first end 114a of the fourth connecting rod 114. The second end 113b of the third connecting rod 113 is rotatably connected to the first shelf 12. The second end 114b of the fourth connecting rod 114 is rotatably connected to the second shelf 13. The first connecting rod 111 and the third connecting rod 113, and the second connecting rod 112 and the fourth connecting rod 114 are symmetrically arranged along a first axis, where the first axis is perpendicular to the first shelf 12, that is, the first axis extends along the z direction. The way the third connecting rod 113 and the fourth connecting rod 114 drive the first shelf 12 and the second shelf 13 is the same as the principle of the way the first connecting rod 111 and the second connecting rod 112 drive the first shelf 12 and the second shelf 13. The arrangement of the third connecting rod 113 and the fourth connecting rod 114 can improve the support stability of the connecting rod assembly 11 for the first shelf 12 and the second shelf 13. In addition, since the first connecting rod 111 and the third connecting rod 113 are symmetric, and the second connecting rod 112 and the fourth connecting rod 114 are symmetric, therefore, the first connecting rod 111 and the third connecting rod 113 always move synchronously, and the second connecting rod 112 and the fourth connecting rod 114 always move synchronously. The distance between the second end 111b of the first connecting rod 111 and the second end 112b of the second connecting rod 112 is always equal to the distance between the second end 113b of the third connecting rod 113 and the second end 114b of the fourth connecting rod 114. Therefore, the first shelf 12 and the second shelf 13 are parallel. Since the first shelf 12 and the second shelf 13 are parallel, therefore, by controlling the rotation of the connecting rod assembly 11, the distance between the first shelf 12 and the second shelf 13 can be accurately adjusted, so as to more accurately allocate the storage space in the inner container 2.
[0037] To facilitate seeing the connection between the shelf assembly 1 and the inner container 2, the inner container 2 further includes a back plate 21. Figure 3 、 Figure 4 The connection schematic diagram between the back plate 21 and the shelf assembly 1 is separately shown in. At this time, the first connecting rod 111 and the second connecting rod 112 are rotatably arranged on the back plate 21. In one embodiment, the rotating shafts of the first connecting rod 111 and the second connecting rod 112 are fixedly arranged on the back plate 21, and both the first end 111a of the first connecting rod 111 and the first end 112a of the second connecting rod 112 can rotate around their respective rotating shafts. In another embodiment, the rotating shaft of the first connecting rod 111 is fixed to the first end 111a of the first connecting rod 111, the rotating shaft of the second connecting rod 112 is fixed to the first end 112a of the second connecting rod 112, and the back plate 21 is provided with shaft holes corresponding to the rotating shaft of the first connecting rod 111 and the rotating shaft of the second connecting rod 112 respectively. The rotating shafts of the first connecting rod 111 and the second connecting rod 112 can rotate in their respective shaft holes. The above connection methods of the first connecting rod 111 and the second connecting rod 112 with the back plate 21 are not restrictive and can be set according to the needs of those skilled in the art. All of the above are within the protection scope of this application.
[0038] In one embodiment, as Figure 3 shown, a first sliding groove 121 is provided on the first shelf 12, a second sliding groove 131 is provided on the second shelf 13, the second end 111b of the first connecting rod 111 is slidably disposed in the first sliding groove 121, and the second end 112b of the second connecting rod 112 is slidably disposed in the second sliding groove 131. When the first connecting rod 111 rotates, the second end 111b of the first connecting rod 111 can move within the first sliding groove 121, so as to ensure that when the first connecting rod 111 drives the first shelf 12 to move, the first shelf 12 can only move in a direction perpendicular to the first shelf 12, and will not cause the first shelf 12 to move in the width direction of the first shelf 12, thereby avoiding the first shelf 12 moving in the width direction of the first shelf 12 (i.e., the direction close to or away from the door body closing the opening of the inner container 2) within the inner container 2 and affecting the opening and closing of the refrigerator door body. The second end 112b of the second connecting rod 112 being slidably disposed in the second sliding groove 131 also ensures that when the second connecting rod 112 drives the second shelf 13 to move, it only moves in a direction perpendicular to the second shelf 13. Since the second shelf 13 is parallel to the first shelf 12, the direction perpendicular to the second shelf 13 is also the direction perpendicular to the first shelf 12. In addition, even if the first shelf 12 and the second shelf 13 move a certain distance in the width direction of the first shelf 12, due to the arrangement of the first sliding groove 121 and the second sliding groove 131, the first shelf 12 and the second shelf 13 can also be pushed to move in the width direction of the first shelf 12 towards the direction close to the back plate 21, thereby avoiding the first shelf 12 and the second shelf 13 from affecting the closing of the refrigerator door body.
[0039] In addition, the first chute 121 and the second chute 131 can also limit the rotation angle of the first link 111 and the second link 112 and the maximum distance between the first shelf 12 and the second shelf 13. Taking the first link 111 as an example, when the second end 111b of the first link 111 rotates away from the second end 112b of the second link 112, the first link 111 rotates along an arc and drives the first shelf 12 to move along the z-axis and the y-axis until the first shelf 12 abuts against the back plate 21. Since the second end 111b of the first link 111 rotates along an arc, when the first shelf 12 is blocked by the back plate 21, the first shelf 12 cannot continue to move along the y-axis. Therefore, the first link 111 can only drive the first shelf 12 to move along the z-axis and the second end 111b of the first link 111 itself moves along the y-axis on the first chute 121. When the second end 111b of the first link 111 slides to one end of the first chute 121 close to the back plate 21, the second end 111b of the first link 111 cannot continue to slide along the y-axis on the first chute 121. At this time, the first link 111 cannot continue to rotate, and the first link 111 drives the first shelf 12 to rotate to the limit position along the z-axis. The movement of the second link 112 driving the second shelf 13 is the same as that of the first link 111. At this time, the second link 112 drives the second shelf 13 to reach the limit position in the opposite direction of the z-axis. At this time, the distance between the first shelf 12 and the second shelf 13 reaches the maximum. The first chute 121 and the second chute 131 play a role in limiting the first link 111 and the second link 112, and at the same time, they also limit the maximum distance between the first shelf 12 and the second shelf 13.
[0040] In one embodiment, as Figure 3 shown, a third chute 122 is provided on the first shelf 12, a fourth chute 132 is provided on the second shelf 13, the second end 113b of the third link 113 is slidably disposed in the third chute 122, and the second end 114b of the fourth link 114 is slidably disposed in the fourth chute 132. The principle of the cooperation between the third chute 122 and the fourth chute 132 and the third link 113 and the fourth link 114 is the same as the principle of the cooperation between the first chute 121 and the second chute 131 and the first link 111 and the second link 112, and will not be elaborated here one by one.
[0041] It should be noted that, as Figure 3 shown, the first chute 121 and the third chute 122 can be two separate chutes, and the second chute 131 and the fourth chute 132 can also be two separate chutes. Of course, as Figure 4As shown, the third slide groove 122 and the first slide groove 121 can also be the same slide groove, namely the first slide groove 121, and the fourth slide groove 132 and the second slide groove 131 can also be the same slide groove, namely the second slide groove 131. At this time, the second end 111b of the first connecting rod 111 and the second end 113b of the third connecting rod 113 share a first slide groove 121, and the second end 112b of the second connecting rod 112 and the second end 114b of the fourth connecting rod 114 share a second slide groove 131. The above is not restrictive and can also be set according to the needs of technical personnel in this field. The above are all within the protection scope of the present application.
[0042] It should also be noted that the first connecting rod 111 and the second connecting rod 112 can be slidably connected to the first shelf 12 and the second shelf 13 along the y-direction through a sliding groove. Of course, the first connecting rod 111 and the second connecting rod 112 can also be only rotatably connected to the first shelf 12 and the second shelf 13 respectively. At this time, the second end 111b of the first connecting rod 111 and the second end 112b of the second connecting rod 112 cannot move relative to the first shelf 12 and the second shelf 13 along the y-direction, and the same is true for the third connecting rod 113 and the fourth connecting rod 114. The above is not restrictive and can be set according to the needs of technical personnel in this field. The above are all within the protection scope of the present application.
[0043] In one embodiment, the shelf assembly 1 further includes a locking member 14, which includes a connecting structure 141 and a locking structure 142 slidably disposed on the connecting structure 141. The first end 111a of the first connecting rod 111 is rotatably connected to the connecting structure 141, and the locking structure 142 can move to a first position and a second position along a direction perpendicular to the first connecting rod 111. In the first position, the locking structure 142 is engaged with the first end 111a of the first connecting rod 111, and the first connecting rod 111 cannot continue to rotate. In the second position, the locking structure 142 is separated from the first connecting rod 111. Since the principle of connecting the connecting structure 141 to the first connecting rod 111 is the same as the principle of connecting the connecting structure 141 to any one of the second connecting rod 112, the third connecting rod 113, and the fourth connecting rod 114, or any two of the transmission connections, as shown in FIG. Figure 5 , Figure 6As shown in the figure, taking the rotatable arrangement of the third link 113 and the fourth link 114 on the connecting structure 141 as an example for introduction. At this time, the locking structure 142 can slide along the x direction. When it slides between the first end 113a of the third link 113 and the first end 114a of the fourth link 114 and engages with the third link 113 and the fourth link 114, neither the third link 113 nor the fourth link 114 can continue to rotate. Since the first link 111, the second link 112, the third link 113, and the fourth link 114 move synchronously, the first link 111 and the second link 112 also no longer continue to rotate. At this time, the first shelf 12 and the second shelf 13 are stably arranged in the inner container 2.
[0044] It should be noted that the above is introduced by taking the rotatable connection of the first end 113a of the third link 113 and the first end 114a of the fourth link 114 with the connecting structure 141 as an example. Of course, any one of the first end 111a of the first link 111, the first end 112a of the second link 112, the first end 113a of the third link 113, and the first end 114a of the fourth link 114 can be set to be rotatably connected to the connecting structure 141. Or, the first end 111a of the first link 111 and the first end 112a of the second link 112 are rotatably connected to the connecting structure 141. At this time, the locking structure 142 can slide along the x direction and lock the link connected to the connecting structure 141, so as to ensure that the link is locked by the locking structure 142 after the link moves in place, ensure that the link can be fixed, and further ensure that the first shelf 12 and the second shelf 13 are stably arranged in the inner container 2.
[0045] In one embodiment, the shelf assembly 1 further includes a support member 15, as Figure 7 、 Figure 8 shown, the support member 15 is provided with an installation groove 151, and the connecting structure 141 is slidably arranged in the installation groove 151. Since the installation groove 151 extends along the width direction of the first shelf 12 and the second shelf 13, the connecting structure 141 can reciprocate in the installation groove 151 along the extension direction of the installation groove 151, that is, the y direction. The setting of the installation groove 151 can guide the movement direction of the connecting structure 141, and the installation groove 151 can also support the connecting structure 141. In addition, since the third link 113 and the fourth link 114 are rotatably connected to the connecting structure 141, the installation groove 151 of the support member 15 can support the connecting structure 141 and the third link 113 and the fourth link 114, so as to ensure the stability of the movement of the third link 113 and the fourth link 114.
[0046] In one embodiment, as Figures 3 to 8As shown, the connecting rod assembly 11 further includes four fifth connecting rods 115. One end of each of the four fifth connecting rods 115 is a gear, and the gears of two of them are meshed with each other to form a closed structure. The other ends of two of the four fifth connecting rods 115 are respectively rotatably connected to the second end 111b of the first connecting rod 111 and the second end 113b of the third connecting rod 113. The other ends of the other two of the four fifth connecting rods 115 are respectively rotatably connected to the second end 112b of the second connecting rod 112 and the second end 114b of the fourth connecting rod 114. Since the four fifth connecting rods 115 rotate through meshing, when one of them rotates, the other three will also rotate synchronously. Moreover, during the rotation of the four fifth connecting rods 115, they always maintain axial symmetry. The arrangement of the four fifth connecting rods 115 can improve the stability of the first connecting rod 111, the second connecting rod 112, the third connecting rod 113, and the fourth connecting rod 114 in supporting the first shelf 12 and the second shelf 13.
[0047] It should be noted that the meshing ends of the four fifth connecting rods 115 can also be slidably arranged along the y direction on the support member 15, and the four fifth connecting rods 115 are all rotatably arranged on the support member 15. At this time, the support member can support the first ends of the fifth connecting rods 115, thereby ensuring the stability of the connection between the fifth connecting rods 115 and the first connecting rod 111 to the fourth connecting rod 114.
[0048] In one embodiment, as Figure 2 shown, there are two sets of connecting rod assemblies 11. The two sets of connecting rod assemblies 11 are symmetrically arranged along the axis of symmetry of the first shelf 12 ( Figure 2 where P is the axis of symmetry of the first shelf 12), and the two sets of connecting rod assemblies 11 are respectively connected to the first shelf 12 and the second shelf 13. At this time, since the two sets of connecting rod assemblies 11 are arranged along the width direction of the first shelf 12 and the second shelf 13, the two sets of connecting rod assemblies 11 can stably support the first shelf 12 and the second shelf 13, thereby ensuring that the first shelf 12 and the second shelf 13 can stably place items.
[0049] In one embodiment, the first end 111a of the first connecting rod 111 and the first end 112a of the second connecting rod 112 are connected by gear meshing transmission. Through gear meshing, the first connecting rod 111 can directly drive the second connecting rod 112 to rotate, and at the same time, it can also save the space occupied by the first end 111a of the first connecting rod 111 and the first end 112a of the second connecting rod 112 in the inner container 2.
[0050] Of course, the first end 111a of the first connecting rod 111 and the first end 112a of the second connecting rod 112 can also be connected by other means. For example, chain connection or pulley connection. The above are not restrictive and can be set according to the needs of those skilled in the art. All of the above are within the protection scope of this application.
[0051] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
