Detailed implementation manners

[0040] The embodiments will be described in detail below, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following embodiments do not represent all implementation manners consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application described in detail in the claims.

[0041] A refrigerator is a refrigerating household appliance, and its main functions include refrigeration, freezing, freshness preservation, temperature adjustment, etc. By circulating the refrigerant, the internal temperature is reduced, so as to achieve the purpose of keeping food fresh.

[0042] Among them, to meet the storage requirements of ingredients at different heights, adjustable shelves are generally provided in the refrigerator. To improve the convenience of shelf adjustment and achieve easy adjustment of the shelf in the refrigerator, some refrigerators are provided with electric lifting shelves, greatly improving the user experience of using the refrigerator.

[0043] To achieve independent adjustment of each layer of the shelf and meet the synchronous lifting of both sides of the shelf, the existing technical solution is to set independent lifting components on both the left and right sides of each layer of the shelf, and configure a driving motor for each lifting module. However, most refrigerators are equipped with double-layer shelves. The above technical solution requires four lifting modules and four driving motors at the same time, which not only makes the assembly complex and costly, but also occupies more internal space of the refrigerator.

[0044] To solve the problems of complex structure of the electric lifting shelf in the refrigerator and large occupation of the internal space of the refrigerator, refer to Figure 1 、 Figure 2 and Figure 3 , some embodiments of the present application provide a shelf assembly, including:

[0045] The storage shelf 21 includes a shelf board 211 and cantilever beams 212 symmetrically arranged on both sides of the shelf board 211; wherein, the shelf board 211 is mainly used to divide the refrigerator compartment into several areas. The cantilever beams 212 are fixed to the structure on both sides of the shelf board 211, and the cantilever beams 212 are mainly used to support the shelf board 211 and allow the shelf board 211 to be suspended inside the refrigerator.

[0046] The sliding plate 229, as Figure 4 shown, includes a fixing member 2291 and a connecting member 2292; the fixing member 2291 is snap-connected to the connecting member 2292; wherein, the fixing member 2291 is a concave structure, the connecting member 2292 is a convex structure, and the protrusion of the connecting member 2292 is inserted into the recess of the fixing member 2291 to snap the fixing member 2291 and the connecting member 2292 together. The sliding plate 229 is mainly used to connect with the cantilever beam 212. By controlling the up and down movement of the sliding plate 229, the up and down movement of the storage shelf 21 is controlled, so as to facilitate the adjustment of the height of the storage shelf 21. At the same time, by setting the fixing member 2291, the fixing member 2291 connects the cantilever beam 212 and the sliding plate 229 together, which is convenient for the installation and disassembly of the cantilever beam 212.

[0047] The lifting module 22, as Figure 3 shown, is symmetrically arranged on both sides of the shelf board 211; the lifting module 22 includes a gear box 24, a support frame 221 and a plurality of lead screws 222; one end of the lead screw 222 is connected to the gear box 24, and the other end of the lead screw 222 is connected to the support frame 221.

[0048] The motor 23, the motor 23 is connected to the gear box 24, and the number of the motors 23 is the same as the number of the storage shelves 21.

[0049] The connecting rod 25 has both ends connected to the gearbox 24 respectively. Among them, the lifting modules 22 are symmetrically arranged on both sides of the partition board. The lifting modules 22 are connected to the storage rack 21 through the sliding plate 229. The lifting modules 22 are provided with gearboxes 24. The horizontally arranged connecting rod 25 and the vertically arranged lead screw 222 are connected together through the gearbox 24, so as to realize that the lead screw 222 in any one of the lifting modules 22 is rotated by controlling the motor 23, and then drive the connecting rod 25 to rotate, and finally drive the lead screw 222 in the other lifting module 22 to rotate, realizing that one motor 23 controls the rotation of the lead screws 222 in the lifting modules 22 on both sides at the same time, and then controls the rising or falling of the shelf 211.

[0050] The support rod 27 has one end connected to the gearbox 24 and the other end connected to the support frame 221; the sliding plate 229 is connected to the cantilever beam 212 through the fixing member 2291; the sliding plate 229 passes through the support rod 27 and is connected to the lead screw 222 through the connecting member 2292. Among them, the support rod 27 is mainly used to guide the movement of the sliding plate 229.

[0051] When it is necessary to adjust the height of the shelf 211, the motor 23 drives the lead screw 222 in the lifting module 22 connected to the motor 23 to rotate. At the same time, the connecting rod 25 connected to the lead screw 222 rotates simultaneously, driving the lead screw 222 on the other side to rotate. Since the sliding plate 229 is connected to the lead screw 222, during the rotation of the lead screw 222, the height of the sliding plate 229 will change with the rotation of the lead screw 222. For example, when the lead screw 222 rotates clockwise, the sliding plate 229 rises. At this time, the sliding plate 229 will drive the storage rack 21 to rise. When the lead screw 222 rotates counterclockwise, the sliding plate 229 descends. At this time, the sliding plate 229 will drive the storage rack 21 to descend, realizing the effect of driving the storage rack 21 to rise or fall by the single-side motor 23.

[0052] In some embodiments, as Figure 5 shown, the gearbox 24 includes a housing 241 and a plurality of transmission groups 242; the transmission group 242 includes a horizontal transmission shaft 2421, a vertical transmission shaft 2422, a horizontal bevel gear 2423, a vertical bevel gear 2424 and a plurality of connecting shafts 2425; the horizontal transmission shaft 2421 is connected to the horizontal bevel gear 2423, the vertical transmission shaft 2422 is connected to the vertical bevel gear 2424, one end of the horizontal transmission shaft 2421 away from the horizontal bevel gear 2423 extends out of the housing 241 and is connected to the connecting shaft 2425; both ends of the vertical transmission shaft 2422 extend out of the housing 241 and are respectively connected to the connecting shaft 2425; the horizontal bevel gear 2423 meshes with the vertical bevel gear 2424.

[0053] Among them, as Figure 6 and Figure 7As shown, when a set of transmission groups 242 are arranged in the gearbox 24, the lifting module 22 can control the lifting of one layer of the storage rack 21. When two sets of transmission groups 242 are arranged in the gearbox 24, the lifting module 22 can control the lifting of two layers of the storage rack 21. In the transmission group 242, a transverse bevel gear 2423 is arranged on the transverse transmission shaft 2421, and a longitudinal bevel gear 2424 is arranged on the longitudinal transmission shaft 2422. By meshing the transverse bevel gear 2423 and the longitudinal bevel gear 2424 together, when the longitudinal transmission shaft 2422 rotates, it will drive the transverse transmission shaft 2421 to rotate. By arranging bevel gears, the transmission direction can be changed, so that when a motor 23 is arranged on one side, the lead screws 222 and the connecting rod 25 on both sides can be driven to rotate simultaneously, realizing synchronous control of the sliding plate 229 to rise or fall.

[0054] It can be understood that multiple sets of the transverse transmission shaft 2421, the longitudinal transmission shaft 2422, the transverse bevel gear 2423 and the longitudinal bevel gear 2424 can be arranged in the gearbox 24. For example, when there is one layer of the storage rack 21, one set of the transverse transmission shaft 2421, the longitudinal transmission shaft 2422, the transverse bevel gear 2423 and the longitudinal bevel gear 2424 is arranged in the gearbox 24. When there are two layers of the storage rack 21, two sets of the transverse transmission shaft 2421, the longitudinal transmission shaft 2422, the transverse bevel gear 2423 and the longitudinal bevel gear 2424 are arranged in the gearbox 24.

[0055] As Figure 7 shown, when two sets of longitudinal transmission shafts 2422 and two sets of longitudinal bevel gears 2424 are arranged, the conical surfaces of the longitudinal bevel gears 2424 on the left and right sides face in opposite directions, that is, if the left side faces down, the right side faces up, or if the left side faces up, the right side faces down.

[0056] In some embodiments, as Figure 8As shown, when there is only one layer of the shelf 21, one end of the longitudinal transmission shaft 2422 is connected to the motor 23 through the connecting shaft 2425, and the other end of the longitudinal transmission shaft 2422 is connected to the lead screw 222 through the connecting shaft 2425; one end of the transverse transmission shaft 2421 is connected to the connecting rod 25 through the connecting shaft 2425. That is, the longitudinal transmission shaft 2422, the transverse transmission shaft 2421, the connecting rod 25, and the lead screw 222 can be used as a transmission group 242. After starting the motor 23, the motor 23 drives the longitudinal transmission shaft 2422 to rotate through the connecting shaft 2425, and the longitudinal transmission shaft 2422 drives the lead screw 222 to rotate through the connecting shaft 2425. At the same time, the longitudinal bevel gear 2424 provided on the longitudinal transmission shaft 2422 rotates, which will drive the meshing transverse bevel gear 2423 to rotate. When the transverse bevel gear 2423 rotates, the transverse transmission shaft 2421, the connecting shaft 2425, the connecting rod 25, the transverse transmission shaft 2421 on the other side, and the transverse bevel gear 2423 connected thereto will rotate simultaneously, thereby driving the longitudinal bevel gear 2424, the longitudinal transmission shaft 2422, and the lead screw 222 on the other side to rotate, realizing that the motor 23 drives the lead screws 222 on both sides to rotate simultaneously, and controlling the sliding plate 229 to rise or fall.

[0057] In some embodiments, as Figure 9 shown, when there are two layers of the shelf 21, two motors 23 can be used to respectively control different transmission groups 242 to drive the lead screws 222 to realize the independent lifting of the double-layer shelf 21. It can be understood that the number of the transmission groups 242, the number of the motors 23, and the number of the shelves 21 are the same. When a double-layer shelf 21 is provided, one motor 23 can be provided in each of the lifting modules 22 on both sides. For example, the right motor 23 drives the upper-layer shelf 21 to lift and lower, and the left motor 23 drives the lower-layer shelf 21 to lift and lower.

[0058] In some embodiments, as Figure 3 shown, a first flanging 2211 is provided at one end of the support frame 221 close to the motor 23, and a second flanging 2212 is provided at the other end of the support frame 221 away from the motor 23; a plurality of first holes are provided in the first flanging 2211, and the longitudinal transmission shaft 2422 passes through the first holes and is connected to the motor 23 through the connecting shaft 2425; a plurality of second holes are provided in the second flanging 2212, and the lead screw 222 passes through the second holes and is connected to the second flanging 2212. Among them, the first flanging 2211 and the second flanging 2212 can, on the one hand, improve the strength and stability of the support frame 221, and on the other hand, by providing the first flanging 2211 and the second flanging 2212, a support surface can be provided to facilitate the arrangement of the lead screw 222 and the support rod 27.

[0059] In some embodiments, the shelf assembly further includes a lead screw nut 226, which is connected to the lead screw 222; the lead screw nut 226 is of a cylindrical structure, and an annular protrusion is provided in the middle of the lead screw nut 226. The connecting member 2292 is provided with a card slot 2293, and the annular protrusion is embedded in the card slot 2293, so that the connecting member 2292 is snap-connected to the lead screw nut 226. Among them, the lead screw nut 226 is of a hollow cylindrical structure, and a thread is provided inside the lead screw nut 226. When the lead screw nut 226 is connected to the lead screw 222 and the lead screw 222 rotates, the lead screw nut 226 will move on the lead screw 222 along with the rotation of the lead screw 222. An annular protrusion is provided on the circumference of the lead screw nut 226, and a card slot 2293 is provided at the open end of the connecting member 2292. During installation, after aligning the card slot 2293 with the annular protrusion and pressing the connecting member 2292, the annular protrusion of the connecting member 2292 can be embedded into the card slot 2293. At this time, the lead screw nut 226 is embedded into the open end of the connecting member 2292, so that the connecting member 2292 is connected to the lead screw nut 226. When the lead screw nut 226 moves as the lead screw 222 rotates, the lead screw nut 226 will drive the connecting member 2292 to rise or fall. By providing the lead screw nut 226, it is convenient for the lead screw 222 to be connected to the sliding plate 229 through the lead screw nut 226, and further convenient to control the lifting movement of the sliding plate 229.

[0060] In some embodiments, such as Figure 10 As shown, the shelf assembly further includes a sliding shaft 228, which is sleeved with the support rod 27; a limiting portion is provided in the middle of the sliding shaft 228, and the sliding plate 229 is provided with a groove corresponding to the limiting portion. The sliding shaft 228 is embedded in the groove and snap-connected to the sliding plate 229. Among them, the sliding shaft 228 is of a hollow cylindrical structure, and several sliding shafts 228 are sleeved on the support rod 27, and the sliding shaft 228 can slide along the support rod 27. Among them, the number of sliding shafts 228 is related to the number of connecting members 2292. One connecting member 2292 connects two sliding shafts 228. After connecting the connecting member 2292 to the lead screw nut 226, the other side of the connecting member 2292 is connected to the sliding shaft 228. On the one hand, after the connecting member 2292 is connected to the sliding shaft 228, the two sliding shafts 228 and one lead screw nut 226 together have three support points. When there are more food ingredients placed on the shelf 211, the sliding shaft 228 abuts against the support rod 27, which can disperse the pressure on the lead screw 222 to prevent the lead screw nut 226 from being subjected to too much force, resulting in the bending of the lead screw 222 and affecting the lifting function of the storage board. At the same time, by providing the sliding shaft 228, the lead screw nut 226 and the two sliding shafts 228 form a plane, which can improve the stability of the lifting of the storage board.

[0061] In some embodiments, such as Figure 10As shown, threads are provided at both ends of the support rod 27. One end of the support rod 27 is connected to the gearbox 24 through a nut, and the other end of the support rod 27 passes through the second hole and is connected to the second flanging 2212 through a nut. One end of the support rod 27 is connected to the gearbox 24 through a nut. The support rod 27 can be fixed to the gearbox 24 through the nut, thereby realizing the support for the gearbox 24. The other end of the support rod 27 passes through the second hole and is connected to the second flanging 2212 through a nut. The other end of the support rod 27 can be fixed to the second flanging 2212 through the nut, thereby realizing the fixation of the support rod 27 between the first flanging 2211 and the second flanging 2212.

[0062] In some embodiments, as Figure 1 shown, it further includes a decorative cover 28. The decorative cover 28 is provided with a through hole 281. The length of the through hole 281 is the same as the length of the lead screw 222. The decorative cover 28 is buckled with the support frame 221, and the cantilever beam 212 passes through the through hole 281 and is connected to the sliding plate 229. During installation, after the lifting module 22 is fixed to the set position of the inner liner of the refrigerator by screws, the decorative cover 28 can be snap-connected to the front of the support frame 221 to cover the gearbox 24, the motor 23, and the lead screw 222, and a moving space for the lifting of the cantilever beam 212 is reserved through the through hole 281. By providing the decorative cover 28, the exposed structural parts of the lifting module 22 are blocked to improve the aesthetics inside the inner liner of the refrigerator.

[0063] In some embodiments, the cantilever beam 212 is provided with a plurality of reinforcing ribs. The extending direction of the reinforcing ribs is the same as the direction of the shelf 211. Among them, the reinforcing ribs are mainly used to enhance the bending resistance of the cantilever beam 212 to ensure that the cantilever beam 212 can effectively resist the bending stress when subjected to a load. The reinforcing ribs are arranged along the length direction of the cantilever beam 212, that is, in the same direction as the shelf 211 connected to the cantilever beam 212, and extend from one end of the cantilever beam 212 to the other end to provide sufficient bearing capacity and stability. When the cantilever beam 212 bears a load, the stress can be dispersed and transmitted through the reinforcing ribs, thereby reducing the risk of bending damage when the cantilever supports the shelf 211.

[0064] In some embodiments, as Figure 11 shown, the embodiment of the present application further provides a refrigerator, including a box body 1 and the shelf assembly 2 provided in the above embodiments. The shelf assembly 2 is arranged inside the box body 1.

[0065] As can be seen from the above technical solutions, the present application provides a shelf assembly, including: a storage shelf 21, including a shelf board 211 and cantilever beams 212 symmetrically arranged on both sides of the shelf board 211; a sliding plate 229, including a fixing member 2291 and a connecting member 2292; a lifting module 22, symmetrically arranged on both sides of the shelf board 211; the lifting module 22 includes a motor 23, a gearbox 24, a support frame 221 and a plurality of lead screws 222; the motor 23 is connected to the gearbox 24, the motor 23 and the gearbox 24 are arranged at one end of the support frame 221, one end of the lead screw 222 is connected to the gearbox 24, and the other end of the lead screw 222 is connected to the support frame 221; a connecting rod 25, both ends of the connecting rod 25 are respectively connected to the gearbox 24; a support rod 27, one end of the support rod 27 is connected to the gearbox 24, and the other end of the support rod 27 is connected to the support frame 221; the sliding plate 229 is connected to the cantilever beam 212 through the fixing member 2291; the sliding plate 229 passes through the support rod 27 and is connected to the lead screw 222 through the connecting member 2292. The present application sets the lifting module 22 and the sliding plate 229 to be connected, and the lifting module 22 matches multiple groups of sliding plates 229 to realize the height conditions of a multi-layer shelf, so as to solve the problems of complex structure and large space occupation of the electric lifting shelf in the refrigerator.
