Among them, the connecting rod group 30 slides along the transverse slide rail group 21 and the vertical slide rail 22, driving the first rack 11 and the second rack 12 to switch between a transverse side-by-side state and a vertical step state.

[0044] In the disclosed embodiment, the second rack 12 is disposed adjacent to the first rack 11, so that the position state can be switched, that is, the first rack 11 and the second rack 12 can be switched between a horizontal side-by-side state and a vertical step state.

[0045] In the disclosed embodiment, the slide rail portion 20 includes a transverse slide rail group 21 and a vertical slide rail 22 connected to the transverse slide rail group 21 , providing guide support for the movement of the second rack 12 and the first rack 11 .

[0046] In the disclosed embodiment, the connecting rod group 30 is connected to both the first rack 11 and the second rack 12, so that the connecting rod group 30 can drive the first rack 11 and the second rack 12 to move. The connecting rod group 30 is slidably matched with the slide rail portion 20, so that the connecting rod group 30 can slide along the slide rail portion 20, that is, the connecting rod group 30 can slide along the horizontal slide rail group 21 and the vertical slide rail 22, so as to drive the first rack 11 and the second rack 12 to switch between the horizontal side-by-side state and the vertical step state.

[0047] When the shelf assembly 10 is applied to the refrigerator 40, when the first shelf 11 and the second shelf 12 are in a vertical step state, it is convenient for users to take and put items, thereby improving the user experience. When the first shelf 11 and the second shelf 12 are in a horizontal side-by-side state, it is convenient to store items, thereby improving the utilization rate of space.

[0048] In the prior art refrigerator, for the shelf on the upper part of the refrigerator, it is difficult for the user to place the items on the shelf close to the inside of the refrigerator, resulting in a waste of space. In this embodiment, when the first shelf 11 and the second shelf 12 are in a vertical step state, the items are placed on the first shelf 11 and the second shelf 12. Then, the first shelf 11 and the second shelf 12 are moved to a horizontal side-by-side state for storage, thereby improving the utilization rate of space.

[0049] Combination Figure 1 and Figure 2 As shown, optionally, the length direction of the first rack 11 is parallel to the length direction of the second rack 12. And the left and right ends of the first rack 11 are flush with the left and right ends of the second rack 12, so that the second rack 12 is arranged adjacent to the first rack 11.

[0050] Combination Figure 1 and Figure 2 As shown, optionally, two groups of connecting rod groups 30 are provided. Two slide rail parts 20 are provided. The two groups of connecting rod groups 30 are symmetrically arranged on both sides of the first rack 11 and the second rack 12. The two slide rail parts 20 are symmetrically arranged on both sides of the first rack 11 and the second rack 12.

[0051] In this embodiment, combined with Figure 1 and Figure 2 As shown, the first rack 11 and the second rack 12 can form a rack as a whole. Two groups of connecting rods 30 are symmetrically arranged on both sides of the first rack 11 and the second rack 12, that is, the two groups of connecting rods 30 are symmetrically arranged on the left and right sides of the rack as a whole. Two slide rails 20 are symmetrically arranged on both sides of the first rack 11 and the second rack 12, that is, the two slide rails 20 are symmetrically arranged on the left and right sides of the rack as a whole. This improves the stability of the first rack 11 and the second rack 12 when switching between the horizontal side-by-side state and the vertical step state.

[0052] Combination Figure 1 and Figure 2 As shown, optionally, the first shelf 11 and the second shelf 12 are both box structures with openings on the top.

[0053] In this embodiment, the first rack 11 and the second rack 12 are both box structures, which improves the stability of the items stored on the first rack 11 and the second rack 12 during the switching between the horizontal side-by-side state and the vertical step state, thereby improving the safety of use.

[0054] Combination Figures 1 to 3 as well as Figure 5 As shown, in some embodiments, the connecting rod group 30 includes a first connecting rod 31 and a second connecting rod 32. The first connecting rod 31 includes a first end 311 movably connected to the first rack 11 and a second end 312 movably connected to the second rack 12.

The first end 311, the second end 312, the third end 321 and the fourth end 322 are all slidably matched with the slide rail portion 20.

[0055] In this embodiment, the first end 311 of the first connecting rod 31 is movably connected to the first rack 11, and the second end 312 of the first connecting rod 31 is movably connected to the second rack 12, so that the first end 311 of the first connecting rod 31 can rotate relative to the first rack 11, and the second end 312 of the first connecting rod 31 can rotate relative to the second rack 12.

[0056] In this embodiment, the third end 321 of the second connecting rod 32 is movably connected to the first rack 11, and the fourth end 322 of the second connecting rod 32 is movably connected to the second rack 12, so that the third end 321 of the second connecting rod 32 can rotate relative to the first rack 11, and the fourth end 322 of the second connecting rod 32 can rotate relative to the second rack 12.

[0057] In this embodiment, by making the second connecting rod 32 parallel to the first connecting rod 31, the first end 311, the second end 312, the third end 321 and the fourth end 322 can form four vertices of a parallelogram structure, thereby achieving stable support for the first shelf 11 and the second shelf 12 and improving the stability of the movement of the first shelf 11 and the second shelf 12.

[0058] In this embodiment, the first end 311, the second end 312, the third end 321 and the fourth end 322 are all slidably matched with the slide rail portion 20 to achieve sliding cooperation between the connecting rod group 30 and the slide rail portion 20, thereby driving the first shelf 11 and the second shelf 12 to switch between the horizontal side-by-side state and the vertical step state.

The third end 321 of the second connecting rod 32 is hinged to the first rack 11. The fourth end 322 of the second connecting rod 32 is hinged to the second rack 12.

[0061] Combination Figure 2 As shown, optionally, when the first shelf 11 and the second shelf 12 are in a horizontally side-by-side state, along the direction from the second shelf 12 to the first shelf 11, the first connecting rod 31 protrudes from the second connecting rod 32, so that the first end 311, the second end 312, the third end 321 and the fourth end 322 form four vertices of a parallelogram structure, thereby achieving stable support for the first shelf 11 and the second shelf 12 and improving the stability of the movement of the first shelf 11 and the second shelf 12.

[0062] Exemplary, combined Figure 1 and Figure 2 As shown, when the first rack 11 and the second rack 12 are in a horizontally parallel state, the direction from the second rack 12 to the first rack 11 is from the back to the front.

[0063] Combination Figure 5As shown, optionally, the connecting rod assembly 30 further includes a first pulley 33, a second pulley 34, a third pulley 35 and a fourth pulley 36.

The third pulley 35 is disposed on a side of the third end 321 of the second connecting rod 32 away from the first rack 11, and the third pulley 35 is slidably matched with the rail portion 20. The fourth pulley 36 is disposed on a side of the fourth end 322 of the second connecting rod 32 away from the second rack 12, and the fourth pulley 36 is slidably matched with the rail portion 20.

[0064] In this embodiment, the first pulley 33, the second pulley 34, the third pulley 35 and the fourth pulley 36 are used to improve the smoothness of the sliding cooperation between the connecting rod group 30 and the slide rail portion 20, thereby improving the smoothness of switching between the horizontal side-by-side state and the vertical step state of the first shelf 11 and the second shelf 12.

[0065] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the transverse rail group 21 includes a first rail 211 and a second rail 212. The second rail 212 is spaced apart from the first rail 211. One end of the second rail 212 is connected to the vertical rail 22. When the first rack 11 and the second rack 12 are in a horizontal side-by-side state, the first rail 211 and the second rail 212 both extend in a direction from the second rack 12 to the first rack 11. The first end 311 and the second end 312 of the first connecting rod 31 both slide in cooperation with the first rail 211. The third end 321 of the second connecting rod 32 slides in cooperation with the second rail 212 and the vertical rail 22. The fourth end 322 of the second connecting rod 32 slides in cooperation with the second rail 212.

[0066] In this embodiment, by setting the second slide rail 212 and the first slide rail 211 at a distance, when the first shelf 11 and the second shelf 12 are in a horizontal side-by-side state, the first slide rail 211 and the second slide rail 212 both extend in the direction from the second shelf 12 to the first shelf 11, so that the first slide rail 211 and the second slide rail 212 can slide and cooperate with the first connecting rod 31 and the second connecting rod 32 set in parallel.

[0067] In this embodiment, the first end 311 and the second end 312 of the first connecting rod 31 are slidably matched with the first slide rail 211 , so that the first end 311 and the second end 312 of the first connecting rod 31 can slide along the first slide rail 211 .

[0068] In this embodiment, one end of the second slide rail 212 is connected to the vertical slide rail 22, and the third end 321 of the second connecting rod 32 slides with both the second slide rail 212 and the vertical slide rail 22, so that the third end 321 of the second connecting rod 32 can slide along the second slide rail 212 and the vertical slide rail 22.

[0069] In this embodiment, the fourth end 322 of the second connecting rod 32 is slidably matched with the second slide rail 212 , so that the fourth end 322 of the second connecting rod 32 can slide along the second slide rail 212 .

[0070] Combination Figure 4 As shown, optionally, the vertical slide rail 22 is arranged to intersect with the second slide rail 212 to achieve switching of the first rack 11 and the second rack 12 between a horizontal side-by-side state and a vertical step state.

[0071] Exemplary, combined Figure 4 As shown, when the first rack 11 and the second rack 12 are in a horizontally parallel state, the direction from the second rack 12 to the first rack 11 is from the back to the front, that is, the first rail 211 and the second rail 212 both extend in the front-to-back direction. In this example, the vertical rail 22 extends in the up-down direction, and the upper end of the vertical rail 22 is connected to the front end of the second rail 212. And along the direction from top to bottom, the vertical rail 22 gradually tilts toward the rear end of the second rail 212.

[0072] Combination Figure 3 and Figure 4 As shown, in some embodiments, the transverse slide rail group 21 further includes a vertical rib 213. The vertical rib 213 is disposed on the first slide rail 211. And the vertical rib 213 separates the first slide rail 211 into a first slide section 2111 and a second slide section 2112. When the first rack 11 and the second rack 12 are in a horizontal side-by-side state, along the direction from the second rack 12 to the first rack 11, the second slide section 2112 and the first slide section 2111 are sequentially disposed. The first end 311 of the first connecting rod 31 is slidably matched with the first slide section 2111. The second end 312 of the first connecting rod 31 is slidably matched with the second slide section 2112.

[0073] In this embodiment, the first slide rail 211 is divided into a first slide section 2111 and a second slide section 2112 by the vertical rib 213, and the first end 311 of the first connecting rod 31 is slidably matched with the first slide section 2111, and the second end 312 of the first connecting rod 31 is slidably matched with the second slide section 2112, so that the first end 311 of the first connecting rod 31 can slide along the first slide section 2111, and the second end 312 of the first connecting rod 31 can slide along the second slide section 2112. In addition, when the first rack 11 and the second rack 12 are in a vertical step state, the vertical rib 213 can limit the second end 312 of the first connecting rod 31 to prevent the second end 312 of the first connecting rod 31 from sliding out of the second slide section 2112, thereby improving the stability of the first rack 11 and the second rack 12 when they are in a vertical step state.

[0074] Combination Figure 3 and Figure 4 As shown, optionally, an opening is provided on one side of the first slide section 2111 away from the second slide section 2112, for allowing the first end 311 of the first connecting rod 31 to slide out of the first slide section 2111, so that the first shelf 11 and the second shelf 12 can be switched from a horizontal side-by-side state to a vertical stepped state.

[0075] Combination Figure 4 As shown, in some embodiments, the rack assembly 10 further includes a limiting groove 13. The limiting groove 13 is disposed in the first slide section 2111. When the first rack 11 and the second rack 12 are in a horizontally parallel state, the first end 311 of the first connecting rod 31 is located at the limiting groove 13.

[0076] In this embodiment, the first end 311 of the first connecting rod 31 is limited by the limiting groove 13, so as to improve the stability of the first rack 11 and the second rack 12 when they are in a horizontal side-by-side state.

[0077] Combination Figure 4 As shown, optionally, the second sliding section 2112 is provided with a limiting groove corresponding to the second end 312 of the first connecting rod 31 to improve the stability of the first rack 11 and the second rack 12 when they are in a horizontal side-by-side state.

The rail portion 20 further includes a support rail 23, which is located on a side of the second rail 212 away from the first rail 211. The support wheel 14 and the support rail 23 are slidably matched.

[0079] In this embodiment, the support wheel 14 is slidably matched with the support rail 23 to enable the support wheel 14 to move relative to the support rail 23, thereby improving the stability of the first shelf 11 and the second shelf 12 when switching between the horizontal side-by-side state and the vertical step state.

[0080] Combination Figure 3 and Figure 4 As shown, optionally, along the direction from back to front, the support rail 23 is arranged to be inclined downward, and the front end of the support rail 23 extends upward.

[0081] In this embodiment, the support rail 23 is tilted downward from the back to the front, which can improve the smoothness of the first rack 11 and the second rack 12 moving from the horizontal side-by-side state to the vertical step state. The front end of the support rail 23 extends upward to stop the support wheel 14, thereby improving the stability of the first rack 11 and the second rack 12 in the vertical step state.

[0082] Combination Figure 4 As shown, optionally, the support rail 23 is provided with a limiting groove corresponding to the support wheel 14 to improve the stability of the first shelf 11 and the second shelf 12 when they are in a horizontal side-by-side state.

[0083] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the slide rail portion 20 further includes an inclined rib 24. The inclined rib 24 is located on a side of the second slide rail 212 away from the first slide rail 211. When the first rack 11 and the second rack 12 are in a horizontally parallel state, the support rail 23 and the inclined rib 24 are sequentially arranged along the direction from the second rack 12 to the first rack 11, and the distance between the inclined rib 24 and the second slide rail 212 gradually increases. When the first rack 11 and the second rack 12 are in a vertical step state, the second connecting rod 32 is mounted on the inclined rib 24.

[0084] In this embodiment, the inclined rib 24 is located on the side of the second slide rail 212 away from the first slide rail 211. When the first shelf 11 and the second shelf 12 are in a horizontal side-by-side state, the supporting slide rail 23 and the inclined rib 24 are sequentially arranged along the direction from the second shelf 12 to the first shelf 11, and the distance between the inclined rib 24 and the second slide rail 212 gradually increases. This enables the second connecting rod 32 to be mounted on the inclined rib 24 to support the second connecting rod 32 when the first shelf 11 and the second shelf 12 are in a vertical step state, thereby improving the stability of the first shelf 11 and the second shelf 12 when they are in the vertical step state.

[0085] For example, when the first rack 11 and the second rack 12 are in a horizontally parallel state, when the direction from the second rack 12 to the first rack 11 is from the back to the front, the inclined rib 24 is located at the front side, and the supporting rail 23 is located at the rear side. Along the direction from the back to the front, the distance between the inclined rib 24 and the second rail 212 gradually increases, so that when the first rack 11 and the second rack 12 are in a vertical step state, the second connecting rod 32 can be placed on the inclined rib 24.

[0086] Combination Figure 3 and Figure 4 As shown, optionally, the slide rail portion 20 further includes a support seat. The first slide rail 211, the second slide rail 212, the vertical slide rail 22, the vertical rib 213, the support slide rail 23 and the inclined rib 24 are all arranged on the support seat.

[0087] When the shelf assembly 10 is applied to the refrigerator 40, the support base provided with the first slide rail 211, the second slide rail 212, the vertical slide rail 22, the vertical rib 213, the support slide rail 23 and the inclined rib 24 can be installed on the inner wall of the refrigerator 40 to improve the installation efficiency.

[0088] Combination Figure 3 and Figure 4 As shown, in some embodiments, one end of the inclined rib 24 away from the supporting rail 23 is close to one end of the vertical rail 22 away from the second rail 212; when the first shelf 11 and the second shelf 12 are in a vertical step state, the third end 321 of the second connecting rod 32 is located at one end of the vertical rail 22 away from the second rail 212.

[0089] In this embodiment, by positioning the end of the inclined rib 24 away from the supporting rail 23 close to the end of the vertical rail 22 away from the second rail 212, it is possible to achieve that when the first shelf 11 and the second shelf 12 are in a vertical step state, the third end 321 of the second connecting rod 32 is located at the end of the vertical rail 22 away from the second rail 212, and the second connecting rod 32 is mounted on the inclined rib 24, thereby improving the stability of the first shelf 11 and the second shelf 12 when they are in the vertical step state.

[0090] Combination Figure 2 and Figure 5 As shown, in some embodiments, the rack assembly 10 further includes an auxiliary wheel 15 . The auxiliary wheel 15 is disposed on the second connecting rod 32 , and the auxiliary wheel 15 is slidably matched with the second slide rail 212 .

[0091] In this embodiment, the auxiliary wheel 15 slides with the second slide rail 212 to improve the smoothness and stability of the switching process between the horizontal side-by-side state and the vertical step state of the first shelf 11 and the second shelf 12.

[0092] Combination Figures 1 to 6 As shown, the embodiment of the present disclosure further provides a refrigerator 40. The refrigerator 40 includes a box body 41 and a shelf assembly 10 as in any of the previous embodiments. The box body 41 defines a storage space 42. The shelf assembly 10 is disposed in the box body 41 and is located in the storage space 42.

[0093] The refrigerator 40 provided in the embodiment of the present disclosure includes a shelf assembly 10. When the first shelf 11 and the second shelf 12 are in a vertical step state, it is convenient for users to take and put items, thereby improving the user experience. When the first shelf 11 and the second shelf 12 are in a horizontal side-by-side state, it is convenient to store items in the refrigerator 40, thereby improving the utilization rate of space.

[0094] Exemplary, combined Figures 1 to 6 As shown, when the rack assembly 10 stores items normally, the first rack 11 and the second rack 12 are in a horizontal side-by-side state. The first rack 11 is located at the front side, and the second rack 12 is located at the rear side. The first slide rail 211, the second slide rail 212, the first connecting rod 31 and the second connecting rod 32 all extend along the front-to-back direction. The vertical ribs 213 are arranged along the up-down direction. The vertical ribs 213 separate the first slide rail 211 into a first slide section 2111 and a second slide section 2112, wherein the first slide section 2111 is located at the front side, and the second slide section 2112 is located at the rear side.

[0095] When the user needs to take or place items, the user pulls the first shelf 11 forward, driving the first end 311 of the first connecting rod 31 to slide along the first sliding section 2111, the second end 312 of the first connecting rod 31 to slide along the second sliding section 2112, the third end 321 of the second connecting rod 32 to slide along the second slide rail 212 and the vertical slide rail 22, and the fourth end 322 of the second connecting rod 32 to slide along the second slide rail 212. Until the first end 311 of the first connecting rod 31 slides out of the first sliding section 2111, and the third end 321 of the second connecting rod 32 slides along the second slide rail 212 and the vertical slide rail 22 to the end of the vertical slide rail 22 away from the second slide rail 212 (the lower end of the vertical slide rail 22), at this time, the second connecting rod 32 is mounted on the inclined rib 24. That is, by moving the second rack 12 forward, the first rack 11 first moves forward and then moves downward, so that the first rack 11 and the second rack 12 move to a vertical step state, which is convenient for users to take and put items.

[0096] After the user takes or places items, he or she lifts and pushes the first rack 11 backward, driving the connecting rod assembly 30 to slide relative to the slide rail 20. That is, the first rack 11 first moves upward and then backward, and the second rack 12 moves backward, so that the first rack 11 and the second rack 12 return to a horizontally parallel state, thereby improving the utilization rate of the space.
