Description

Technical Field

[0001] This invention relates to the field of household appliance manufacturing technology, and in particular to a lifting device for storage equipment and the storage equipment itself. Background Technology

[0002] As society develops, users have increasingly higher requirements for the storage performance of refrigerators. To meet these needs and improve the user experience, many improvement solutions have emerged for refrigerators, such as increasing their height.

[0003] In related technologies, the shelves in the upper storage space of tall refrigerators are often quite high off the ground. A lifting mechanism is used to raise and lower these shelves to allow items to be accessed. However, before the high shelves can be lowered, items on the shelves below them must be removed to make room for the higher shelves. Removing items from the shelves below the higher shelves is cumbersome, making it inconvenient to access items in the upper storage space of the refrigerator. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a lifting device for storage equipment, which can realize closed-loop lifting of the supporting component, thereby facilitating users to retrieve and place items.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0063] An embodiment of the first aspect of the present invention provides a lifting device for storage equipment. Figure 1 A schematic diagram of the structure of the lifting device for storage equipment provided in an embodiment of the present invention is illustrated, such as... Figure 1As shown, the lifting device for storage equipment includes a lifting mechanism and at least one support member 3; wherein, the lifting mechanism includes a drive component 2 and a lifting unit 1, the lifting unit 1 includes a first closed-loop lifting component 11 and a second closed-loop lifting component 12 with identical structures, the first closed-loop lifting component 11 and the second closed-loop lifting component 12 are both suitable for installation on the same side wall of the storage equipment; the drive component 2 is respectively connected to the first closed-loop lifting component 11 and the second closed-loop lifting component 12 to drive the first closed-loop lifting component 11 and the second closed-loop lifting component 12 to move synchronously; at least one support member 3 is arranged at intervals along the movement direction of the first closed-loop lifting component 11, and the first end of the support member 3 is rotatably connected to the first closed-loop lifting component 11, and the second end of the support member 3 is rotatably connected to the second closed-loop lifting component 12.

[0064] It is understandable that the drive component 2 drives the first closed-loop lifting component 11 and the second closed-loop lifting component 12 to move synchronously in the same direction, such as... Figure 1 As shown, the arrows indicate the movement directions of the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12. Figure 1 The diagram shows that both the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12 rotate in a clockwise direction.

[0065] It is understandable that the first end of the carrier 3 is rotatably connected to the first closed-loop lifting assembly 11, which can drive the first end of the carrier 3 to move. The second end of the carrier 3 is rotatably connected to the second closed-loop lifting assembly 12, which can drive the second end of the carrier 3 to move. Under the synchronous drive of the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12, the carrier 3 can be raised or lowered. At the same time, the two ends of the carrier 3 are rotatably connected to the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12 respectively, which can ensure that the carrier 3 always maintains the same horizontal posture during the process of the carrier 3 changing from the rising state to the falling state (or from the falling state to the rising state).

[0066] According to an embodiment of the present invention, the lifting device for storage equipment drives the rotation of the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12, which are identical in structure and located on the same side wall, via the driving assembly 2. This rotation drives the movement of the support member 3 connected to the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12. The two ends of the support member 3 are rotatably connected to the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12, respectively. This ensures that the support member 3 always maintains the same horizontal posture, thereby enabling the adjustment of the position of the support member 3. This allows the user to easily move the support member 3 from a high position to a location convenient for the user to pick up and put down items, facilitating the user's use and preventing the user from being injured by falling objects.

[0067] Figure 2A schematic diagram of the lifting mechanism provided in an embodiment of the present invention is shown. Figure 3 Example Figure 1 A magnified view of point A in the diagram, as shown below. Figure 2 and Figure 3 As shown, the distance between the first closed-loop lifting assembly 11 and the side wall of the storage device is greater than the distance between the second closed-loop lifting assembly 12 and the side wall of the storage device; the second closed-loop lifting assembly 12 is at least partially located between the first closed-loop lifting assembly 11 and the side wall of the storage device.

[0068] Understandable Figure 2 The four arrows in the middle, from left to right, represent the upward direction of the first closed-loop lifting component 11, the upward direction of the second closed-loop lifting component 12, the downward direction of the first closed-loop lifting component 11, and the downward direction of the second closed-loop lifting component 12, respectively.

[0069] It is understandable that during the upward movement of the support member 3, the first end of the support member 3 is connected to one side of the first closed-loop lifting assembly 11 in the upward direction, and the second end of the support member 3 is connected to one side of the second closed-loop lifting assembly 12 in the upward direction; during the downward movement of the support member 3, the first end of the support member 3 is connected to one side of the first closed-loop lifting assembly 11 in the downward direction, and the second end of the support member 3 is connected to one side of the second closed-loop lifting assembly 12 in the downward direction; when there are multiple support members 3, and both the upward and downward directions of the first closed-loop lifting assembly 11 are connected to the support member 3, in order to avoid interference between the upward and downward support members 3, this embodiment makes the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12 have an interlaced part, that is, there is a distance difference between the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12 and the side wall of the storage device, which can be that the distance between the first closed-loop lifting assembly 11 and the side wall of the storage device is greater than the distance between the second closed-loop lifting assembly 12 and the side wall of the storage device.

[0070] According to an embodiment of the present invention, the lifting device for storage equipment is designed with an interleaved portion between the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12, which can avoid interference between the rising support member 3 and the falling support member 3.

[0071] In one embodiment of the present invention, such as Figure 3 As shown, the first closed-loop lifting assembly 11 includes a transmission bar 112 and several transmission components 111. The drive assembly 2 can be connected to the transmission bar 112 or to one of the transmission components 111.

[0072] It is understandable that several transmission components 111 are spaced apart and rotatably connected to the side wall of the storage equipment, and transmission bars 112 are sleeved on several transmission components 111. The arrangement of several transmission components 111 can be reasonably designed according to needs. For example, several transmission components 111 can be arranged in a rectangular shape, a racetrack shape, or other closed-loop structure. The structural form of transmission bars 112 corresponds to the closed-loop trajectory formed by several transmission components 111.

[0073] It is understandable that all the transmission components 111 of the first closed-loop lifting assembly 11 can be rotatably connected to the side wall of the storage device, the transmission bar 112 can rotate relative to the transmission component 111, the output of the drive assembly 2 can be power-coupled with the transmission bar 112, and the drive assembly 2 can directly drive the transmission bar 112 to rotate, thereby driving the carrier 3 to move during the rotation of the transmission bar 112; the output of the drive assembly 2 can also be connected to one of the transmission components 111, and the transmission bar 112 can drive the transmission bar 112 to rotate, and the transmission bar 112 can drive the carrier 3 to move.

[0074] It is understood that the transmission bar 112 can be a transmission belt, and the transmission component 111 can be a transmission wheel that cooperates with the transmission belt; the transmission bar 112 can also be a transmission chain, and the transmission component 111 can be a transmission sprocket that cooperates with the transmission chain. In other embodiments, the first closed-loop lifting assembly 11 can also be other transmission structures.

[0075] It should be noted that the structure of the second closed-loop lifting component 12 is the same as that of the first closed-loop lifting component 11, and will not be described again in this embodiment.

[0076] It is understood that the drive assembly 2 may include two drive motors, which are respectively connected to one of the transmission components 111 of the first closed-loop lifting assembly 11 and one of the transmission components 111 of the second closed-loop lifting assembly 12. Alternatively, the two drive motors may be dynamically coupled to the transmission bar 112 of the first closed-loop lifting assembly 11 and the transmission bar 112 of the second closed-loop lifting assembly 12, respectively, so that the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12 can be driven to rotate in the same direction by the two drive motors.

[0077] It is also understood that the drive assembly 2 has a first side and a second side, the transmission bar 112 of the first closed-loop lifting assembly 11 is dynamically coupled to the first side of the drive assembly 2, and the transmission bar 112 of the second closed-loop lifting assembly 12 is dynamically coupled to the second side of the drive assembly 2.

[0078] It is understandable that, such as Figure 2As shown, the portion where the second closed-loop lifting assembly 12 intersects with the first closed-loop lifting assembly 11 forms the installation space for the drive assembly 2. Specifically, the installation space is formed between the transmission bar located in the upward direction of the second closed-loop lifting assembly 12 and the transmission bar located in the downward direction of the first closed-loop lifting assembly 11. The drive assembly 2 includes a drive motor and a drive shaft. The drive motor is mounted on the side wall of the storage device, and the drive shaft is coaxially connected to the output shaft of the drive motor. The drive shaft has a first side that engages with the transmission bar located in the upward direction of the second closed-loop lifting assembly 12, and a second side that engages with the transmission bar located in the downward direction of the first closed-loop lifting assembly 11. The drive shaft is driven by the drive motor in a downward direction... Figure 2 When rotated clockwise, the transmission bar 112 of the first closed-loop lifting assembly 11 and the transmission bar 112 of the second closed-loop lifting assembly 12 can rotate clockwise simultaneously.

[0079] It is understandable that by using a single drive motor to drive the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12 to rotate synchronously, the synchronicity of their movements can be ensured. At the same time, compared with two drive motors, the structure is simpler and the cost is reduced.

[0080] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12 each have four transmission components 111. The four transmission components 111 are arranged in a rectangular shape. Two of the transmission components 111 are suitable for installation on the top of the storage device, and the other two transmission components 111 are located in the middle or lower part of the storage device.

[0081] Understandably, taking the first closed-loop lifting assembly 11 as an example, by installing two of the transmission components 111 on the top of the storage device, items on the higher-positioned support member 3 at the top of the storage device can be moved to a position convenient for the user to retrieve and place items. The other two transmission components 111 can be located in the middle of the storage device, so that the support member 3 between the top and middle of the storage device can be freely lifted and lowered, and the lower part of the storage device can adopt a conventional placement method. The other two transmission components 111 can also be located in the lower part of the storage device, so that the support member 3 of the entire internal space of the storage device can achieve closed-loop lifting and lowering, so that the user does not need to squat down to retrieve and place items at lower positions, thereby improving the convenience of user use.

[0082] Figure 4 A schematic diagram of the structure of the carrier provided in the embodiment of the present invention is illustrated. Figure 5 Example Figure 1 A magnified view of section B in the diagram, as shown below. Figure 4 and Figure 5As shown, the first end of the carrier 3 is provided with a first connecting part 31, which is rotatably connected to the first closed-loop lifting assembly 11; the second end of the carrier 3 is provided with a connecting part 32, which is rotatably connected to the second closed-loop lifting assembly 12 and forms a clearance space 33, and the first closed-loop lifting assembly 11 is at least partially located in the clearance space 33.

[0083] It is understood that the first end of the carrier 3 is provided with a first connecting part 31 that is rotatably connected to the first closed-loop lifting assembly 11; the first connecting part 31 can connect a rod, and correspondingly, a first mounting hole that cooperates with the connecting rod is opened on the transmission bar 112 of the first closed-loop lifting assembly 11. The carrier 3 and the first closed-loop lifting assembly 11 are rotatably connected by the first connecting part 31 in the first mounting hole of the transmission bar 112 of the first closed-loop lifting assembly 11.

[0084] It is understandable that the second end of the carrier 3 is provided with a connecting component 32. Since there is an intersecting part between the transmission bar 112 of the first closed-loop lifting assembly 11 and the transmission bar 112 of the second closed-loop lifting assembly 12, the connecting component 32 at the second end of the carrier 3 should have a clearance space 33 so that the first closed-loop lifting assembly 11 is at least partially located in the clearance space 33, thereby avoiding interference between the transmission bar 112 of the first closed-loop lifting assembly 11 and the transmission bar 112 of the second closed-loop lifting assembly 12 during their movement.

[0085] It is also understood that the connecting component 32 includes a clearance part 321 and a second connecting part 322. The clearance part 321 is connected to the second end of the carrier 3. The clearance part 321 has an open clearance groove on the side away from the second closed-loop lifting assembly 12, and the clearance groove forms a clearance space 33. The second connecting part 322 is connected to the clearance part 321 and is rotatably connected to the second closed-loop lifting assembly 12.

[0086] It is understandable that the second connecting part 322 can also be a connecting rod. Accordingly, a second mounting hole that cooperates with the connecting rod is opened on the transmission bar 112 of the second closed-loop lifting assembly 12. The second connecting part 322 is rotatably set in the second mounting hole of the transmission bar 112 of the second closed-loop lifting assembly 12, thereby realizing the rotatable connection between the bearing member 3 and the second closed-loop lifting assembly 12.

[0087] It is understandable that when there are multiple carriers 3, multiple spaced first mounting holes are opened on the transmission bar 112 of the first closed-loop lifting assembly 11. The first ends of the multiple carriers 3 are respectively rotatably set on the multiple first mounting holes of the transmission bar 112 of the first closed-loop lifting assembly 11. At the same time, multiple spaced second mounting holes are also opened on the transmission bar 112 of the second closed-loop lifting assembly 12. The number of second mounting holes corresponds to the number of first mounting holes, and their positions correspond one-to-one. The second ends of the multiple carriers 3 are respectively rotatably set on the multiple second mounting holes of the transmission bar 112 of the second closed-loop lifting assembly 12. This realizes the rotational connection between the carriers 3 and the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12, and ensures that the carriers 3 remain horizontal during the rotation of the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12.

[0088] It should be noted that each carrier 3 has a first connecting part 31 at its first end and a connecting part 32 at its second end. The carrier 3 can be stably supported on the first closed-loop lifting assembly 11 and the second closed-loop lifting assembly 12 through the first connecting part 31 and the connecting part 32. Thus, the carrier 3 can move under the drive of a lifting mechanism, thereby ensuring that the shelf 7 on the carrier 3 always moves in a horizontal state.

[0089] According to an embodiment of the present invention, a lifting device for a storage device has a carrier 3 provided with a first connecting part 31 and a connecting component 32, and the connecting component 32 forms a clearance space 33. The first closed-loop lifting assembly 11 is at least partially located in the clearance space 33, which can avoid interference between the movement process of the transmission bar 112 of the first closed-loop lifting assembly 11 and the transmission bar 112 of the second closed-loop lifting assembly 12.

[0090] In a preferred embodiment of the present invention, there are two lifting mechanisms, and the two lifting mechanisms are respectively adapted to be installed on two opposite side walls of the storage device; each lifting mechanism is connected to at least one bearing member 3, and the bearing members 3 on the two lifting mechanisms correspond one-to-one.

[0091] It is understandable that by moving the two lifting mechanisms in sync, the load-bearing components 3 on the two lifting mechanisms can be moved. The two corresponding load-bearing components 3 on the two lifting mechanisms form a load-bearing unit. A shelf 7 is placed on each load-bearing unit, so that each shelf 7 is supported between the two corresponding load-bearing components 3, thereby improving the stability of the movement of the shelf 7 on the support.

[0092] A second aspect of the present invention provides a storage device. Figure 6 One of the structural schematic diagrams of the storage device provided in the embodiment of the present invention is illustrated. Figure 7 A second schematic diagram of the structure of the storage device provided in an embodiment of the present invention is shown. Figure 8 Example 3 illustrates the structure of the storage device provided in the embodiment of the present invention, such as...
