Description

Refrigerator with a refrigerator body

Technical Field

The application relates to the technical field of refrigeration, in particular to a refrigerator.

Background

A refrigerator is a refrigerating apparatus that maintains a constant low temperature, and is mainly used for storing and preserving foods, beverages, and various materials. Refrigerators are used in home kitchens, shops, supermarkets, offices and other settings.

The refrigerator has a plurality of shelves therein, which are spaced apart, and which can be used to place foods, beverages, and various materials. The refrigerator shelves in the market at present are generally fixedly supported through the refrigerator liner grooves so as to support various articles. Since the volume of each article is small, there is a case where the article having a large volume cannot be placed on the shelves (the size of the article is larger than the distance between two adjacent shelves). Thus, the position of the shelf needs to be adjusted.

When the shelf is adjusted in position, the user needs to remove the articles placed on the shelf and then install the shelf in a new position. As a result, the use of the device is troublesome, and the use experience of the user is deteriorated.

Disclosure of utility model

The application provides a refrigerator which is used for solving the technical problem that the use experience of a user is affected because the position of a refrigerator shelf is troublesome to adjust in the related art.

In order to achieve the above purpose, the application adopts the following technical scheme:

The application provides a refrigerator, which comprises: the box body, layer frame, supporting component and drive assembly, the box body forms and holds the chamber, holds the chamber and can be used for holding articles such as food. The layer is erected in the accommodating cavity and is used for placing articles. In this way, articles or the like can be placed on the shelves for storage in the receiving chamber.

The supporting component is located in the accommodating cavity and connected with the box body, and the supporting component is used for supporting the layer frame. The support assembly includes: the first connecting rod comprises a first end and a second end which are opposite, and the first end of the first connecting rod is hinged with the layer frame. The second link includes opposite third and fourth ends, an axis of the second link being coplanar with an axis of the first link. The third end of the second link is hinged to the second end of the first link. The fourth end of the second connecting rod is hinged with the box body. The support assembly may support the shelf.

The drive assembly is connected with at least one of the first link and the second link.

The driving assembly can drive the second end of the first connecting rod to rotate around the first end of the first connecting rod so as to drive the layer rack to lift.

After the driving assembly is started, the driving assembly drives the second end of the first connecting rod to rotate around the first end of the first connecting rod, and the axis of the first connecting rod can be gradually close to the vertical direction. Simultaneously, the third end part of the second connecting rod also rotates around the fourth end part, and the axis of the second connecting rod is gradually close to the vertical direction, so that the layer rack is driven to rise.

Similarly, when the driving assembly drives the second end of the first link to rotate around the first end of the first link in a direction opposite to the rotating direction, the axis of the first link gradually approaches to the horizontal direction. Simultaneously, the third end part of the second connecting rod reversely rotates around the fourth end part, and the axis of the second connecting rod gradually approaches to the horizontal direction, so that the layer rack is driven to descend.

After the driving component is closed, the driving component stops driving the second end part of the first connecting rod to rotate around the first end part of the first connecting rod. Meanwhile, the third end part of the second connecting rod cannot rotate around the fourth end part, so that the height of the layer frame cannot change, and the layer frame can be kept at a certain height.

Thus, when the shelf is adjusted in position (height), the user does not need to remove the articles placed on the shelf and then mount the shelf to a new position. The user can adjust the height of the shelf only by opening and closing the driving assembly. Thus, the use of the device is more convenient for users.

In some embodiments of the present application, the plurality of support assemblies are in a square structure, and the support assemblies are arranged at corners of the shelf. In this way, the stability of the support assembly supporting the shelves (and articles) may be improved.

In some embodiments of the application, the drive assembly includes a motor disposed on one of the shelf, the box, or the first and second links, an output shaft of the motor being connected to the other of the first and second links. In this way, the user can adjust the height of the shelf by turning the motor on and off.

In some embodiments of the application, the drive assembly further comprises a reduction gear, an input end of the reduction gear is in transmission connection with the output shaft of the motor, an output end of the reduction gear is connected with the first link or the second link, and the reduction gear is used for reducing the rotation speed of the output shaft.

It will be appreciated that a reduction in the rotational speed of the motor (where the input power to the motor is constant) may increase the torque of the motor output shaft. Under the heavier circumstances of the article of placing on layer frame and the layer frame, can guarantee like this that drive assembly still can drive the second tip of first connecting rod and rotate around the first tip of first connecting rod to drive layer frame and go up and down.

In some embodiments of the application, the motor is provided on one of the first link and the second link, and an output shaft of the motor is connected to the other of the first link and the second link. The motor is coaxially arranged with the speed reduction transmission device. Therefore, after the motor is started, the output end of the speed reduction transmission device can drive the second end part of the first connecting rod to rotate around the first end part of the first connecting rod so as to drive the layer rack to lift.

And/or the reduction gearing is a planetary reducer. The stability of the planetary reducer is strong, so that the stability of transmission can be improved. In addition, the planetary reducer has strong bearing capacity and can bear larger load, so that the planetary reducer can adapt to the lifting of a heavier layer rack (and articles).

In some embodiments of the present application, the driving assembly includes a first linear driver, the two supporting assemblies are located in the same plane, the first linear driver is disposed on one of the two supporting assemblies located in the same plane, an output end of the first linear driver is connected with the other one of the two supporting assemblies located in the same plane, and rotation directions of two first connecting rods of the two supporting assemblies located in the same plane are opposite.

After the first linear driver is started, the output end of the first linear driver can realize linear reciprocating motion. And under the condition that the output end of the first linear driver moves towards one direction, and the hinge shafts of the first connecting rods and the second connecting rods of the two supporting components are far away from each other, the second end parts of the first connecting rods of the two supporting components can rotate around the first end parts of the first connecting rods, so that the layer rack can be driven to ascend or descend.

Similarly, when the output end of the first linear driver moves in the opposite direction of the direction, and the hinge shafts of the first connecting rod and the second connecting rod of the two supporting components are close to each other, the second end parts of the first connecting rods of the two supporting components can rotate around the first end parts, so that the layer rack can be driven to descend or ascend.

After the first linear driver is closed, the output end of the first linear driver stops moving, and the hinge shafts of the first connecting rods and the second connecting rods of the two supporting components are not close to each other or far away from each other, that is, the second end parts of the first connecting rods of the two supporting components are not rotated around the first end parts, so that the height of the layer frame is not changed, and the layer frame can be kept at a certain height.

Thus, when the shelf is adjusted in position (height), the user does not need to remove the articles placed on the shelf and then mount the shelf to a new position. The user only needs to open and close the first linear driver to adjust the height of the layer rack, and the use is convenient.

In some embodiments of the present application, in two support assemblies located in the same plane, a first linear actuator is provided at the hinge of the first link and the second link of one support assembly, and an output end of the first linear actuator is connected to the hinge of the first link and the second link of the other support assembly.

It will be appreciated that the output of the first linear actuator may be connected at other locations than at other locations of the first and second links such that more force is generated at the output of the first linear actuator to urge the first link to rotate, i.e. the output of the first linear actuator is more efficient.

In some embodiments of the application, the two support assemblies lie in the same plane. The second end of the first connecting rod of one supporting component is fixedly connected with the third end of the second connecting rod of the other supporting component, and the second end of the first connecting rod of the other supporting component is fixedly connected with the third end of the second connecting rod of the one supporting component.

The hinge axes of the first and second links in one support assembly are the same as the hinge axes of the first and second links in the other support assembly.

In one of the support assemblies, the first end of the first connecting rod is connected with the layer rack in a sliding mode, and the fourth end of the second connecting rod is connected with the box body in a sliding mode.

In one support assembly, the first end of the first link slides in a direction on the shelf and the fourth end of the second link rotates about one end with the fourth end of the second link sliding in the direction on the box. At the same time, the fourth end of the second link of the other support assembly rotates in the same direction about the third end of the second link, with the axes of both links gradually approaching the vertical direction.

Similarly, the first link of the other support assembly and the second link of one support assembly also gradually approach the vertical direction. Thus, the layer rack can be driven to ascend.

In one supporting assembly, the first end of the first link slides on the shelf in a direction opposite to the above-mentioned one direction, and in the case where the fourth end of the second link slides on the case in a direction opposite to the above-mentioned one direction, both the first link and the second link of the other supporting assembly gradually approach the horizontal direction with reference to the above-mentioned case. The first connecting rod of the other supporting component and the second connecting rod of the supporting component are gradually close to the vertical direction, so that the layer frame can be driven to descend.

In some embodiments of the application, the drive assembly includes a second linear actuator hinged to one of the first and second links in the same support assembly, and an output end of the second linear actuator is hinged to the other of the first and second links.

After the second linear driver is started, the output end of the second linear driver can drive the second end part of the first connecting rod in the two supporting components to rotate around the first end part of the first connecting rod, so that the layer frame can be driven to lift.

The application provides a refrigerator, comprising: the box body, layer frame, supporting component and drive assembly, the box body forms and holds the chamber, and the layer frame is in holding the intracavity for place article. The supporting component is located in the accommodating cavity and connected with the box body, and the supporting component is used for supporting the layer frame.

The support assembly includes: the first connecting rod comprises a first end and a second end which are opposite, and the first end of the first connecting rod is hinged with the layer frame. The second link includes opposite third and fourth ends, an axis of the second link being coplanar with an axis of the first link. The third end of the second link is hinged to the second end of the first link. The fourth end of the second connecting rod is hinged with the box body.

The driving component is used for driving the second end part of the first connecting rod to rotate around the first end part of the first connecting rod so as to drive the layer rack to lift.

The functions and beneficial effects of the components identical to those of the above technical solution can be referred to the above description, and the description of the present application will not be repeated.

Thus, when the shelf is adjusted in position, the user does not need to remove the articles placed on the shelf and then install the shelf in a new position. The user only needs to open and close the drive assembly to adjust the height of the layer rack, and the use is convenient.

A refrigerator is a refrigerating apparatus that maintains a constant low temperature, and is mainly used for storing and preserving foods, beverages, and various materials. Refrigerators are used in home kitchens, shops, supermarkets, offices and other settings.

The refrigerator has a plurality of shelves therein, which are spaced apart, and which can be used to place foods, beverages, and various materials. The refrigerator shelves in the market at present are generally fixedly supported through the refrigerator liner grooves so as to support various articles. Since the volume of each article is small, there is a case where the article having a large volume cannot be placed on the shelves (the size of the article is larger than the distance between two adjacent shelves). Thus, the position of the shelf needs to be adjusted.

When the shelf is adjusted in position, the user needs to remove the articles placed on the shelf and then install the shelf to a new position (new height). As a result, the use of the device is troublesome, and the use experience of the user is deteriorated.

The patent publication No. CN112240665A proposes a refrigerator with a lifting shelf, which provides a technical solution for lifting the shelf of the refrigerator, but has the following drawbacks:

1. The lifting structure is complex, the cost is high, and the assembly is difficult. 2. The two ends of the layer frame are hung by steel wires, are not rigidly supported, can shake in the lifting process or the using process, and are easy to skew. 3. The steel wire pulley structure can produce great noise in the use.

The patent publication No. CN211120242U proposes a refrigerator with a lifting layer rack, and also provides a technical scheme for realizing lifting of the layer rack of the refrigerator, in the technical scheme, supporting points of the layer rack are all arranged at the rear of the layer rack, when an object is positioned at the front, the gravity of the object can cause larger pressure on the mechanism, the friction force is increased, the mechanism can be caused to operate inflexibly, or the layer rack leans forward to cause the object to slide.

Fig. 1 is a schematic diagram of a partial structure of a refrigerator according to an embodiment of the present application. In order to solve the technical problem that the adjustment of the position of the refrigerator shelf 10 in the related art is troublesome and affects the use experience of the user, an embodiment of the present application provides a refrigerator, which includes a refrigerator body, as shown in fig. 1, and further includes: the shelf 10, the support assembly 20 and the drive assembly 30 (not shown in fig. 1).

Wherein, the box body is formed with a holding cavity. The receiving chamber may be used to receive items such as food. The receiving chamber may be a refrigerating chamber or a freezing chamber of a refrigerator in daily life, for example.

Fig. 2 is a schematic diagram of a partial structure of a refrigerator according to an embodiment of the present application. The layer rack 10 is arranged in the accommodating cavity and is used for accommodating articles. As shown in fig. 2, the shelf 10 may be a plate, etc., and a plane of the plate surface of the plate may be parallel to a horizontal plane. In this manner, items and the like may be placed on the shelves 10 for storage in the receiving chamber.

Illustratively, as further shown in fig. 2, the refrigerator may further include a shelf mounting frame 11, wherein the shelf mounting frame 11 is disposed in the refrigerator body, and a chute is formed on the shelf mounting frame 11, and extends along an edge of the shelf 10 (extends in a horizontal direction). The edges of the shelves 10 fit within the runners.

Specifically, as further shown in fig. 2, the number of shelf mounts 11 is two and located on opposite sides of the shelf 10. The shelf mount 11 is symmetrical about the centre line of the shelf 10.

Thus, it is convenient for the user to slide the shelf 10 along the extending direction of the chute to take the shelf 10 out of the refrigerator or put the shelf 10 into the refrigerator.

The support assembly 20 is located in the receiving chamber and is connected to the case. As further shown in fig. 1, the support assembly 20 is used to support the shelf 10.

Fig. 3 is an enlarged view at a in fig. 1. As further shown in fig. 1, it is understood that the support assembly 20 may be positioned at the bottom of the shelf 10 in the height direction of the refrigerator, and the support assembly 20 includes: a first link 21 and a second link 22, the first link 21 comprising opposite first and second ends a, b. As shown in fig. 1 and 3, the first end a of the first link 21 is hinged with the shelf 10.

Illustratively, articulation is a relatively common manner of connection. For example, one of the first end a of the first link 21 and the shelf 10 may be provided with a hinge shaft. For example, as shown in fig. 3, the refrigerator may further include a support base 40, the support base 40 may be provided to the shelf mounting frame 11 (or to the shelf 10), and a hinge shaft may be provided on the support base 40.

Specifically, referring to fig. 1 and 3, the axis of the hinge shaft may be parallel to the horizontal direction, the hinge shaft may include opposite first and second ends, the first end of the hinge shaft may be connected with the first end a of the first link 21, the second end of the hinge shaft may be connected with the support seat 40, and the hinge shaft may be rotatably connected (e.g., rotatably connected by a bearing) with at least one of the first end a of the first link 21 and the support seat 40. In this way, the first end a of the first link 21 may be hinged with the shelf 10.

Illustratively, a first end of the hinge shaft may be connected with one of the first end a of the first link 21 and the support seat 40, and a second end of the hinge shaft may penetrate the other of the first end a of the first link 21 and the support seat 40 (e.g., the other of the first end a of the first link 21 and the support seat 40 may be opened with a through hole). In addition, the hinge shaft may be further provided with a limiting structure (e.g., a nut, a limiting protrusion, etc.) at the second end side.

Therefore, the two can be hinged, and the limiting structure can prevent the two from being separated from the hinge shaft. Of course, the embodiment of the present application may also implement hinging in other manners, and the embodiment of the present application is not limited thereto.

As further shown in fig. 1, the second link 22 includes opposed third and fourth ends c, d, it being understood that the axis of the second link 22 and the axis of the first link 21 may be coplanar. Further, as further shown in fig. 1, the plane in which the axes of the first link 21 and the second link 22 are located may be perpendicular to the plane (horizontal plane) in which the plate surface of the shelf 10 is located.

Of course, the plane where the axis of the first connecting rod 21 and the axis of the second connecting rod 22 are located may also form a certain included angle with the plane where the board of the shelf 10 is located, which is not limited in the embodiment of the present application.

Fig. 4 is an enlarged view at B in fig. 1. As further shown in fig. 1, the second link 22 includes opposed third and fourth ends c, d. As shown in fig. 1 and 4, the third end c of the second link 22 is hinged with the second end b of the first link 21.

Fig. 5 is an enlarged view at C in fig. 1. As shown in fig. 1 and 5, the fourth end d of the second link 22 may be hinged with the case. Thus, the support assembly 20 can support the shelf 10.

Illustratively, as shown in fig. 5, a support seat 40 may be provided on the case, and a fourth end d of the second link 22 may be hinged to the support seat 40.

In other figures, the hinge of the first link 21 with the shelf 10, the hinge of the first link 21 with the second link 22, and the hinge of the second link 22 with the case may be analogically referred to.

Fig. 6 is a third schematic diagram of a partial structure of a refrigerator according to an embodiment of the present application. Illustratively, in the case where the refrigerator includes one support assembly 20 as shown in fig. 6, the support assembly 20 may be located at one side of the shelf 10, and the other side of the shelf 10 may be slidably coupled with the inner wall 12 of the cabinet (the sliding direction of the shelf 10 may be perpendicular to the horizontal plane).

For example, the other end of the shelf 10 may be provided with one of a slider (or a pulley) and a guide rail, the inner wall 12 of the case may be provided with the other one of a slider (or a pulley) and a guide rail, and the extending direction of the guide rail may be parallel to the horizontal plane. In this way, the support assembly 20 can also support the shelf 10, and the shelf 10 can be lifted.

Illustratively, as further shown in FIG. 1, the support assembly 20 may also be a plurality. The shape of the shelf 10 may be a square structure, for example, as shown in fig. 1 and 2, the shape of the shelf 10 may be a rectangular parallelepiped. Of course, the shape of the shelf 10 may be a cube or the like.

As further shown in fig. 1, support assemblies 20 may be provided at the corners of the shelf 10. In this way, the stability of the support assembly 20 and the (article) support shelf 10 can be improved.

Illustratively, the shelves may also be other shapes. For example, a disk shape, etc.

For example, the number of support members 20 may be two. Alternatively, the plane in which the two support assemblies 20 lie may be perpendicular to the horizontal plane and may pass through the center of gravity of the shelf 10.

In particular, the plane in which the support assembly 20 lies may be parallel to the line along the edges of the shelf 10. Of course, the plane in which the support assembly 20 lies may also be parallel to the diagonal of the shelf 10.

The planes of the two support members 20 may be the same plane. The planes of the two support assemblies 20 may not be the same plane, which is not limited in the embodiment of the present application.

Fig. 7 is a front view of a shelf 10 and a support assembly 20 according to an embodiment of the present application. Fig. 8 is a left side view of one of the shelves 10 and the support assembly 20 provided in accordance with an embodiment of the present application. As shown in fig. 1, 7 and 8, the number of the supporting members 20 may be four, the four supporting members 20 may be divided into two groups, and two supporting members 20 in one group may be the same plane, where the two supporting members 20 in each group are respectively located.

The planes of the two sets of support members 20 may be parallel. The planes of the two sets of support assemblies 20 may also be non-parallel, which is not limited in this embodiment of the application.

More specifically, the first links 21 of the four support members 20 may be positioned at four corners of the shelf 10 where they are hinged to the shelf 10. Of course, the hinge connection between the first links 21 of the four support assemblies 20 and the shelf 10 may not be located at the four corners of the shelf 10, which is not limited by the embodiment of the present application.

The driving assembly 30 is used for driving the second end b of the first link 21 to rotate around the first end a of the first link 21 so as to drive the shelf 10 to lift.

The driving assembly 30 is connected with at least one of the first link 21 and the second link 22. For convenience of description, the specific connection of the driving assembly 30 will not be described herein, and reference will be made to the following description.

Thus, an embodiment of the present application provides a refrigerator, including: the case, the shelf 10, the supporting assembly 20 and the driving assembly 30 are formed with a receiving cavity which can be used to receive food and the like. The layer rack 10 is arranged in the accommodating cavity and is used for accommodating articles. In this manner, items and the like may be placed on the shelves 10 for storage in the receiving chamber.

The support assembly 20 is located in the accommodating cavity and connected with the box body, and the support assembly 20 is used for supporting the layer frame 10. The support assembly 20 includes: a first link 21 and a second link 22, the first link 21 including opposite first and second ends a and b, the first end a of the first link 21 being hinged to the shelf 10. The second link 22 includes opposite third and fourth ends c, d, the axis of the second link 22 and the axis of the first link 21 being coplanar. The third end c of the second link 22 is hinged to the second end b of the first link 21. The fourth end d of the second link 22 is hinged to the box. The support assembly 20 may support the shelf 10.

The driving assembly 30 is connected with at least one of the first link 21 and the second link 22.

The driving assembly 30 can drive the second end b of the first link 21 to rotate around the first end a of the first link 21, so as to drive the shelf 10 to lift.

Fig. 9 is a schematic structural view (left side view) of a layer frame 10 and a supporting component 20 according to an embodiment of the present application. After the driving assembly 30 is opened, the axis of the first link 21 may gradually approach the vertical direction when the driving assembly 30 drives the second end b of the first link 21 to rotate around the first end a of the first link 21. At the same time, the third end c of the second link 22 also rotates around the fourth end d, and the axis of the second link 22 also gradually approaches the vertical direction, thereby driving the shelf 10 to rise. As shown in fig. 9, it can be appreciated that in the case where the shelf 10 is raised to the highest, the axis of the first link 21 and the axis of the second link 22 may both be parallel to (or very close to) the vertical direction.

Fig. 10 is a second (left side view) schematic diagram of a layer frame 10 and a supporting component 20 according to an embodiment of the present application. Similarly, in the case where the driving unit 30 drives the second end b of the first link 21 to rotate around the first end a of the first link 21 in the direction opposite to the above-described rotation direction, the axis of the first link 21 gradually approaches the horizontal direction. At the same time, the third end c of the second link 22 also rotates reversely around the fourth end d, and the axis of the second link 22 also gradually approaches the horizontal direction, thereby driving the shelf 10 to descend. As shown in fig. 10, it can be understood that in the case where the shelf 10 is lowered to the lowest position, the axis of the first link 21 and the axis of the second link 22 may both be parallel to (or very close to) the horizontal direction.

After the driving assembly 30 is closed, the driving assembly 30 stops driving the second end b of the first link 21 to rotate around the first end a of the first link 21. Meanwhile, the third end c of the second link 22 does not rotate about the fourth end d, and thus, the height of the shelf 10 does not change, so that the shelf 10 can be maintained at a certain height.

In this way, the user does not need to remove the articles placed on the shelf 10 before installing the shelf 10 in a new position when the shelf 10 is adjusted in position (height). The user can adjust the height of the shelf 10 by simply turning on and off the driving assembly 30. Thus, the use of the device is more convenient for users.

Fig. 11 is a schematic structural diagram of a driving assembly 30 according to an embodiment of the application. In some embodiments, as shown in fig. 11, the drive assembly 30 may include a motor 31. The motor 31 may be provided to one of the shelf 10, the case, or the first and second links 21 and 22, and the output shaft 311 of the motor 31 may be connected to the other of the first and second links 21 and 22. In this way, the user can adjust the height of the shelf 10 by turning on and off the motor 31.

Illustratively, the motor 31 may be a (small) servomotor. The motor 31 may also be of other types, for example. The embodiment of the present application is not limited thereto.

The above description: the driving assembly 30 is connected with at least one of the first link 21 and the second link 22.

Illustratively, the drive assembly 30 (i.e., the motor 31) may be coupled to both the first and second links 21, 22. For example, the motor 31 may be provided at one of the first and second links 21 and 22, and the output shaft 311 of the motor 31 may be connected to the other of the first and second links 21 and 22.

For example, the motor 31 may be disposed at the second link 22 at a hinge of the first link 21 and the second link 22, the output shaft 311 of the motor 31 may be connected to the first link 21, and the output shaft 311 of the motor 31 may be connected to the first link 21 at a rotation axis where the first end a of the first link 21 rotates about the second end b of the first link 21. The axis of the output shaft 311 of the motor 31 may or may not be collinear with the axis of rotation of the first end a of the first link 21 about the second end b of the first link 21 (this may be achieved by providing a pair of bevel gears for meshing drive).

Thus, after the motor 31 is driven, the output shaft 311 of the motor 31 can drive the second end b of the first link 21 to rotate around the first end a of the first link 21, so as to drive the shelf 10 to lift.

Of course, the motor 31 may be disposed on the first link 21, and the specific manner of disposing the motor 31 may be similar to the case where the motor 31 is disposed on the second link 22.

Illustratively, the drive assembly 30 may be coupled with one of the first and second links 21, 22.

Specifically, the motor 31 may be further provided to the shelf 10, and the output shaft 311 of the motor 31 may be connected to the first link 21 or the second link 22. For example, the output shaft 311 of the motor 31 may be connected to the first link 21, and the output shaft 311 of the motor 31 may be connected at a rotation axis where the second end b of the first link 21 rotates about the first end a of the first link 21.

Thus, after the motor 31 is turned on, the output shaft 311 of the motor 31 may drive the second end b of the first link 21 to rotate around the first end a of the first link 21.

For example, the output shaft 311 of the motor 31 may also be connected to the second link 22, and the output shaft 311 of the motor 31 may be connected to the second link 22 at a rotation axis where the third end c of the second link 22 rotates about the fourth end d of the second link 22.

Thus, after the motor 31 is turned on, the output shaft 311 of the motor 31 may drive the third end c of the second link 22 to rotate around the fourth end d of the second link 22, so as to drive the second end b of the first link 21 to rotate around the first end a of the first link 21.

Specifically, the motor 31 may be further provided to the case (the inner wall 12), and the output shaft 311 of the motor 31 may be connected to the first link 21 or the second link 22. For example, the output shaft 311 of the motor 31 may be connected to the second link 22, and may be connected to the second link 22 at a rotation axis where the third end c of the second link 22 rotates about the fourth end d of the second link 22.

After the motor 31 is turned on, the output shaft 311 of the motor 31 may drive the third end c of the second link 22 to rotate around the fourth end d of the second link 22, so as to drive the second end b of the first link 21 to rotate around the first end a of the first link 21, thereby driving the shelf 10 to lift.

For example, the output shaft 311 of the motor 31 may also be connected to the first link 21, and may be connected to the second end b of the first link 21 at a rotational axis about which the first end a of the first link 21 rotates.

Thus, after the motor 31 is started, the output shaft 311 of the motor 31 may drive the second end b of the first link 21 to rotate around the first end a of the first link 21.

Further, in one support assembly 20, the number of the motors 31 may be set as the case may be (the number of the motors 31 may be set to 0).

For example, in the case where the number of the above-mentioned supporting members 20 is one, the number of the motors 31 is at least one.

In the case where the number of the motors 31 is one, the arrangement of one motor 31 may be referred to as one arrangement of the motors 31.

In the embodiment of the application, only one motor 31 is arranged, so that the second end b of the first connecting rod 21 can be driven to rotate around the first end a of the first connecting rod 21, and the layer frame 10 is driven to lift. In this way, costs can be saved.

In the case where the number of motors 31 is plural, for example, the number of motors 31 is 6. The above describes six arrangements of the motors 31, and one motor 31 of the plurality of motors 31 may refer to one arrangement of the motors 31 described above.

In the embodiment of the present application, 6 motors 31 are provided, and it can be understood that the acting force for driving the shelf 10 to lift is greater, so that the shelf 10 can bear greater gravity (for example, heavier objects are placed on the shelf 10), so as to meet the use requirement of a user.

Of course, the number of motors 31 may be 2, 3, 4, or 5, and the arrangement of the motors 31 may be referred to the arrangement of the 6 motors 31. The number of motors 31 may be greater than 6, and the arrangement modes of the motors 31 other than 6 may be specific, for example, the number of motors 31 using the same arrangement mode may be multiple, or the motors 31 may also drive the second end b of the first link 21 to rotate around the first end a of the first link 21 in other arrangement modes, and may drive the layer frame 10 to lift.

In the case where the number of the above-described support assemblies 20 is two, the number of the motors 31 in one support assembly 20 is at least one, and the manner of setting the motors 31 can be described with reference to the above.

In the case that the number of the support assemblies 20 is four, at least one motor 31 may be disposed on two support assemblies 20 diagonally opposite to the layer frame 10 (square structure), at least one motor 31 may be disposed on three support assemblies 20 among the four support assemblies 20, or at least one motor 31 may be disposed on the four support assemblies 20. The motor 31 may be arranged in the manner described above.

Fig. 12 is a second schematic structural diagram of a driving assembly 30 according to an embodiment of the application. In some embodiments, as shown in fig. 11 and 12, the drive assembly 30 may further include a reduction gear 32, and the reduction gear 32 may include three external gears 322 and an internal gear 323, all four in driving connection. The input 321 of the reduction gear 32 is in driving connection (for example by means of a gear drive connection) with the output shaft 311 of the motor 31, the output (i.e. the annulus 323) of the reduction gear 32 being connected to the first connecting rod 21 (not shown in fig. 11 and 12) or to the second connecting rod 22 (not shown in fig. 11 and 12), the reduction gear 32 being used to reduce the rotational speed of the output shaft 311 of the motor 31.

It will be appreciated that a decrease in the rotational speed of the motor 31 (in the case where the input power of the motor 31 is constant) may increase the torque of the output shaft 311 of the motor 31. In the case of heavy weight of the shelf 10 and the articles placed on the shelf 10, it is ensured that the driving assembly 30 can still drive the second end b of the first link 21 to rotate around the first end a of the first link 21, thereby driving the shelf 10 to lift.

For example, as shown in fig. 12, the reduction gear 32 may be a planetary reducer. The stability of the planetary reducer is strong, so that the stability of transmission can be improved. In addition, the planetary reducer has a high bearing capacity and can bear a high load, so that the planetary reducer can adapt to the lifting of the heavy layer frame 10 (and articles).

The reduction gear 32 may also be a worm reducer or the like, for example. By way of example, reduction gear 32 may also be other gear reducers, such as a spur gear reducer, a conical-spur gear reducer, and the like.

For example, as shown in fig. 11, the motor 31 and the reduction gear 32 may be coaxially disposed. Of course, when the reduction gear 32 is of another type, the motor 31 and the reduction gear 32 may be disposed on different axes, and the embodiment of the present application may be determined according to the circumstances.

Thus, after the motor 31 is turned on, the output end of the reduction transmission device 32 can drive the second end b of the first connecting rod 21 to rotate around the first end a of the first connecting rod 21, so as to drive the shelf 10 to lift. Fig. 13 is a second left side view of a shelf 10 and a support assembly 20 according to an embodiment of the present application. In some embodiments, as shown in fig. 13, the driving assembly 30 may include a first linear driver 33, where the two support assemblies 20 are located in the same plane, the first linear driver 33 is disposed on one of the two support assemblies 20 located in the same plane, and an output end 331 of the first linear driver 33 is connected to the other one of the two support assemblies 20 located in the same plane, and rotation directions of the two first links 21 of the two support assemblies 20 located in the same plane are opposite.

After the first linear actuator 33 is turned on, the output end 331 of the first linear actuator 33 can perform linear reciprocating motion. When the output end 331 of the first linear actuator 33 moves in one direction and the hinge shafts of the first link 21 and the second link 22 of the two support members 20 are away from each other, the second end b of the first link 21 of the two support members 20 can rotate around the first end a of the first link 21, thereby driving the shelf 10 to ascend or descend.

Similarly, when the output end 331 of the first linear actuator 33 moves in the opposite direction to the above direction, the hinge shafts of the first link 21 and the second link 22 of the two support assemblies 20 approach each other, the second end b of the first link 21 of the two support assemblies 20 can rotate around the first end a of the first link 21, thereby driving the shelf 10 to descend or ascend.

After the first linear actuator 33 is turned off, the output end 331 of the first linear actuator 33 stops moving, and the hinge shafts of the first link 21 and the second link 22 of the two support members 20 are not moved toward or away from each other, i.e., the second ends b of the first link 21 of the two support members 20 are not rotated about the first ends a of the first link 21, so that the height of the shelf 10 is not changed, thereby maintaining the shelf 10 at a certain height.

In this way, the user does not need to remove the articles placed on the shelf 10 before installing the shelf 10 in a new position when the shelf 10 is adjusted in position (height). The user can adjust the height of the shelf 10 by only turning on and off the first linear driver 33, which is convenient for use.

It should be noted that, with respect to the embodiment shown in fig. 13, four support assemblies 20 and a plurality of first linear drives 33 are provided in the embodiment of the present application, the arrangement of two support assemblies 20 on the right side may refer to the left side view, and the arrangement of the first linear drives 33 on the right side may refer to the above description.

Illustratively, the first linear actuator 33 may be an electric push rod, a cylinder, a hydraulic cylinder, or the like.

Illustratively, the two support assemblies 20 are arranged in two ways. For example, as further shown in fig. 13, during the ascent of the shelf 10 (or with the rotation of the second end b of the first link 21 about the first end a of the first link 21), the hinge axes of the first link 21 and the second link 22 in the two support assemblies 20 may be away from each other. And the hinge axes of the first link 21 and the second link 22 of the two support assemblies 20 may be close to each other during the descent of the shelf 10.

In this way, the first link 21 and the second link 22 may not occupy additional space in the lifting process of the shelf 10, thereby saving space in the refrigerator.

Fig. 14 is a third left side view of a shelf 10 and a support assembly 20 according to an embodiment of the present application. For example, as shown in fig. 14, the hinge shafts of the first link 21 and the second link 22 in the two support assemblies 20 may also approach each other during the ascent of the shelf 10. And the hinge axes of the first link 21 and the second link 22 in the two support assemblies 20 may be away from each other during the descent of the shelf 10.

Specifically, with respect to fig. 14, four support assemblies 20 and a plurality of first linear drives 33 are also provided in the embodiment of the present application, and the arrangement of two support assemblies 20 on the right side may refer to the left view, and the arrangement of the first linear drives 33 on the right side may refer to the left view.

In some embodiments, as shown in fig. 13 and 14, in two support assemblies 20 located in the same plane, a first linear actuator 33 is provided at the hinge of the first link 21 and the second link 22 of one support assembly 20, and an output end 331 of the first linear actuator 33 is connected to the hinge of the first link 21 and the second link 22 of the other support assembly 20.

It will be appreciated that the force generated by the output 331 of the first linear actuator 33 may be more effective to urge the first link 21 to rotate, i.e., the output of the first linear actuator 33 may be more efficient, than if the first linear actuator 33 were coupled to other locations of the first link 21 and the second link 22, and the output 331 of the first linear actuator 33 is coupled to other locations.

Illustratively, the first linear actuator 33 may be coupled (e.g., may be hinged) to the hinge shafts of the first and second links 21, 22 of one support assembly 20, and the output 331 of the first linear actuator 33 may be coupled (e.g., may be hinged) to the hinge shafts of the first and second links 21, 22 of the other support assembly 20.

Illustratively, the first linear actuator 33 may be coupled to either the first link 21 or the second link 22 in one of the support assemblies 20 and located at the hinge of the first link 21 and the second link 22. The output 331 of the first linear actuator 33 may be connected to the first link 21 or the second link 22 of the other support assembly 20 and located at the hinge of the first link 21 and the second link 22 of the other support assembly 20.

Fig. 15 is a left side view of a shelf 10 and a support assembly 20 according to an embodiment of the present application. In other embodiments, as shown in fig. 15, in two support assemblies 20 that are located in the same plane, a first linear actuator 33 is provided at the first link 21 or the second link 22 of one support assembly 20, and is not located at the hinge of the first link 21 and the second link 22. The output 331 of the first linear actuator 33 is connected to the first link 21 or the second link 22 of the other support assembly 20, and may not be located at the hinge of the first link 21 and the second link 22.

With respect to fig. 15, the embodiment of the present application also provides four support assemblies 20 and a plurality of first linear drives 33, and the two support assemblies 20 on the right side may be disposed in a manner that references the left view, and the first linear drives 33 on the right side may be disposed in a manner that references the left view.

Thus, after the first linear driver 33 is turned on, the output end 331 of the first linear driver 33 performs linear motion, so as to drive the first connecting rod 21 in the two support assemblies 20 to rotate (the second end b of the first connecting rod 21 rotates around the first end a of the first connecting rod 21), thereby driving the shelf 10 to lift.

As an example, continuing to refer to fig. 15, the first linear actuator 33 may be hinged with the first link 21 of one support assembly 20 and may be located at the center of the first link 21 of one support assembly 20. The output end 331 of the first linear actuator 33 may be hinged to the first link 21 of the other support member 20 and located at the center of the first link 21 of the other support member 20.

After the first linear driver 33 is turned on, the output end 331 of the first linear driver 33 can implement linear reciprocating motion, and the output end 331 of the first linear driver 33 can drive the first connecting rod 21 in the two support assemblies 20 to rotate (the second end b of the first connecting rod 21 rotates around the first end a of the first connecting rod 21), and meanwhile, the first linear driver 33 can rotate around the hinge shaft of the first connecting rod 21 with the two support assemblies 20, so that the layer frame 10 can be driven to lift.

Of course, the first linear actuator 33 may be hinged to the first link 21 of one support assembly 20, and may not be located at the center of the first link 21 of one support assembly 20. The output end 331 of the first linear actuator 33 may be hinged to the first link 21 of the other support assembly 20, and may not be located at the center of the first link 21 of the other support assembly 20.

Furthermore, the first linear actuator 33 may be hinged to the first link 21 of one support assembly 20, and the output 331 of the first linear actuator 33 may be hinged to the second link 22 of the other support assembly 20.

Fig. 16 is a fifth left side view of a shelf 10 and a support assembly 20 according to an embodiment of the present application. Illustratively, as shown in fig. 16, the first linear actuator 33 may also be hinged with the second link 22 of one support assembly 20, and may be located at the center of the second link 22 of one support assembly 20. The output end 331 of the first linear actuator 33 may also be hinged to the second link 22 of the other support assembly 20, and may be located at the center of the second link 22 of the other support assembly 20.

For the embodiment shown in fig. 16, four support assemblies 20 and a plurality of first linear drives 33 are provided in the embodiment of the present application, and the two support assemblies 20 on the right side of the layer frame 10 may be disposed in a manner referred to as a left view, and the first linear drives 33 on the right side of the layer frame 10 may be disposed in a manner referred to as a left view.

The above description: the driving assembly 30 is connected with at least one of the first link 21 and the second link 22, and the first link 21 and the second link 22 herein should be understood as the first link 21 and the second link 22 in one support assembly 20.

Illustratively, the drive assembly 30 may be coupled to one of the first and second links 21, 22 in one support assembly 20. In the case where the above-described shelf 10 is of a square structure, the number of the supporting members 20 is four, and the supporting members 20 are respectively provided at the corners of the shelf 10, for example.

Specifically, the embodiments shown in fig. 13, 14, 15, and 16 (and the illustrative descriptions of the corresponding drawings) are all cases in which the driving assembly 30 (the first linear driver 33) is connected to one of the first link 21 and the second link 22 in one support assembly 20 located in the same plane (the plane is named as the first plane, which may be located on one side of the shelf 10, which may be located on the side seen from the left view), and one of the first link 21 and the second link 22 in the other support assembly 20.

In addition, the number of the first linear drivers 33 may be plural, and each of the plurality of first linear drivers 33 may be disposed in the manner described above, and the plurality of first linear drivers 33 may cooperate to rotate the second end b of the first link 21 about the first end a of the first link 21.

Also, two support assemblies 20 located on the other plane (this plane is named as the second plane, which may be located on the other side of the shelf 10, and the second plane may be located on the side of the right view) also need to be provided with the first linear drives 33, and the number and arrangement of the first linear drives 33 may be referred to in the case of the first plane.

Specifically, the first linear actuator 33 may also be provided to the shelf 10 (e.g., the first linear actuator 33 may be hinged to the shelf 10), and the output end 331 of the first linear actuator 33 may be hinged to one of the first link 21 and the second link 22 in one of the support assemblies 20.

Thus, after the first linear actuator 33 is turned on, the first linear actuator 33 can also drive the second end b of the first link 21 in one support assembly 20 to rotate around the first end a of the first link 21.

In addition, in the case where the first linear drivers 33 are disposed on the layer frame 10, a plurality of first linear drivers 33 are required in the embodiment of the present application, for example, four first linear drivers 33 are provided (corresponding to the case where the layer frame 10 has a square structure and the layer frame 10 includes four support members 20, and the four support members 20 are disposed at the corners of the layer frame 10, respectively), and one first linear driver 33 is connected to one of the first link 21 and the second link 22 in one support member 20 (for connection, reference may be made to the description above).

Alternatively, three first linear drives 33 may be provided in the embodiment of the present application, and the three first linear drives 33 are connected to three support assemblies 20 of the four support assemblies 20 in a one-to-one correspondence manner.

Alternatively, two first linear drives 33 may be provided, where the two support assemblies 20 are respectively connected to two support assemblies 20 located at opposite angles of the layer frame 10 in the four support assemblies 20 in a one-to-one correspondence manner.

Illustratively, the first linear actuator 33 may also be disposed within the housing (e.g., the first linear actuator 33 may be hinged to the housing, and the output 331 of the first linear actuator 33 may be hinged to one of the first and second links 21, 22.

Thus, after the first linear actuator 33 is turned on, the first linear actuator 33 may also drive the second end b of the first link 21 to rotate around the first end a of the first link 21.

Illustratively, the first linear drive 33 may also be coupled to both the first and second links 21, 22 in one support assembly 20. For example, the first linear actuator 33 may be hinged at the center of the first link 21 in one support assembly 20, and the output 331 of the first linear actuator 33 may be hinged at the center of the second link 22 in one support assembly 20.

Thus, after the first linear actuator 33 is turned on, the first linear actuator 33 may also drive the second end b of the first link 21 to rotate around the first end a of the first link 21.

Fig. 17 is a sixth left side view of a shelf 10 and a support assembly 20 according to an embodiment of the present application. In some embodiments, as shown in fig. 17, two support assemblies 20 are located in the same plane, the second end b of the first link 21 of one support assembly 20 is fixedly connected to the third end c of the second link 22 of the other support assembly 20, and the second end b of the first link 21 of the other support assembly 20 is fixedly connected to the third end c of the second link 22 of one support assembly 20.

The hinge axes of the first link 21 and the second link 22 in one support assembly 20 are the same as the hinge axes of the first link 21 and the second link 22 in the other support assembly 20.

Referring to fig. 17, in one of the support assemblies 20, a first end a of a first link 21 is slidably connected to the shelf 10, and a fourth end d of a second link 22 is slidably connected to the case.

In one support assembly 20, the second end b of the first link 21 rotates about the first end a of the first link when the first end a of the first link 21 slides in a certain direction and the fourth end d of the second link 22 also slides in the certain direction. Meanwhile, the fourth end d of the second link 22 of the other support assembly 20 rotates in the same direction about the third end c of the second link 22, with the axes of both links gradually approaching the vertical direction.

Similarly, the first link 21 of the other support assembly 20 and the second link 22 of one support assembly 20 are also gradually closer to the vertical direction. Thus, the shelf 10 can be driven to rise.

In one support assembly 20, in the case where the first end portion a of the first link 21 slides on the shelf 10 in a direction opposite to the above-described one direction and the fourth end portion d of the second link 22 slides on the case in a direction opposite to the above-described one direction, both the first link 21 and the second link 22 of the other support assembly 20 gradually come closer to the horizontal direction with reference to the above-described case. The first link 21 of the other support assembly 20 and the second link 22 of one support assembly 20 are also gradually close to the vertical direction, so that the shelf 10 can be driven to descend.

As an example, continuing to refer to fig. 17, the first link 21 of one support assembly 20 and the second link 22 of the other support assembly 20 may be integrally formed. Further, as further shown in fig. 17, the axes of the two links may be collinear. The first link 21 of the other support assembly 20 and the second link 22 of one support assembly 20 may also be integrally formed. The axes of the two links may be collinear.

Illustratively, the second end b of the first link 21 of one support assembly 20 and the third end c of the second link 22 of the other support assembly 20 may also be only fixedly connected, and the second end b of the first link 21 of the other support assembly 20 and the third end c of the second link 22 of the one support assembly 20 may also be only fixedly connected.

In particular, the axis of the first link 21 of one support assembly 20 and the axis of the second link 22 of the other support assembly 20 may not be collinear. The first link 21 of one support assembly 20 and the first link 21 of the other support assembly 20 may be symmetrical about a vertical line passing through a common hinge axis. The second link 22 of one support assembly 20 and the second link 22 of the other support assembly 20 may be symmetrical about a vertical line passing through a common hinge axis.

In this way, the lifting of the shelf 10 can be achieved during the rotation of the first links 21 of the two support assemblies 20.

Illustratively, the first end a of the first link 21 may be provided with a pulley or a slider, and the shelf 10 (bottom) may be provided with a rail on which the pulley or slider may roll (or slide). The fourth end d of the second link 22 may be connected to a pulley or a slider, and the inside (bottom) of the case may be provided with a rail on which the pulley or the slider may slide.

Thus, the first end a of the first link 21 may be slidably connected to the shelf 10, and the fourth end d of the second link 22 may be slidably connected to the case.

Specifically, as further shown in fig. 17, the driving assembly 30 includes a second linear actuator 34, and in the same supporting assembly 20, the second linear actuator 34 is hinged to one of the first link 21 and the second link 22, and an output end of the second linear actuator 34 is hinged to the other of the first link 21 and the second link 22.

After the second linear driver 34 is turned on, the output end of the second linear driver 34 may drive the second end b of the first link 21 in one support assembly 20 to rotate around the first end a of the first link 21, and it may be understood that the rotation of the first link 21 in one support assembly 20 may also drive the rotation of the first link 21 in the other support assembly 20, so as to drive the lifting of the layer frame 10.

The second linear actuator 34 may be, for example, an electric push rod, a cylinder, a hydraulic cylinder, or the like.

It should be noted that, in the embodiment of the present application, only one driving assembly 30 (the motor 31 and the reduction gear 32) may be provided.
