DETAILED DESCRIPTION

[0033] See also Figure 1 The utility model provides a foldable shelf assembly, comprising:

[0034] The rear plate 2 can rotate around a specific fulcrum; see Figure 5 and Figure 6 , side panels 23 are provided on both sides of the rear panel 2, and support grooves 24 are provided on the inner sides of the side panels 23;

[0035] As an embodiment, a rear shaft 21 is fixed on both sides of the rear end of the rear plate 2; the rear plate 2 can rotate around the rear shaft 21 as a fulcrum;

[0036] See also Figure 3 and Figure 4, the front plate 1, both sides of which are respectively fixed with support bosses 14 for rotationally cooperating with the support groove 24 on the corresponding side;

[0037] Specifically:

[0038] Combine Figure 9 When the rear panel 2 rotates upward with a fixed fulcrum, the support boss 14 rotates in the support groove 24, so that the front panel 1 and the rear panel 2 are in a vertical stacked state, thereby forming an avoidance in the vertical direction.

[0039] When the front panel 1 and the rear panel 2 are both in a horizontal position, objects can be placed thereon.

[0040] Better yet, the rear end of the front panel 1 has a front panel guide surface 13, and the front end of the rear panel 2 has a rear panel guide surface 22; when in a horizontal posture, the panel guide surface 13 and the rear panel guide surface 22 fit together; they jointly bear the load and maintain the horizontal posture of the two.

[0041] See also Figure 9 As an embodiment of the foldable shelf assembly, both sides of the front panel 1 and the rear panel 2 are provided with support strips 5 for bearing the load.

[0042] See also Figure 8 Furthermore, a pressure plate 51 is provided above both sides of the front end of the front panel 1; the pressure plate 51 is configured to prevent the front end of the front panel 1 from tilting.

[0043] As an embodiment of the cooperation between the support boss 14 and the support groove 24, a sliding groove 25 is provided in the support groove 24; a rotating shaft 15 cooperating with the sliding groove 25 is provided on the support boss 14; a track surface 241 is formed on the bottom side of the support groove 24; specifically:

[0044] When the front plate 1 and the rear plate 2 are both in a horizontal posture, the rotating shaft 15 is located at one end in the sliding groove 25 ; the upper outer side surface of the supporting boss 14 abuts against the top inner side surface of the sliding groove 25 .

[0045] The present invention supports and maintains the horizontal posture of the front plate 1 and the rear plate 2 through the cooperation between the rotating shaft 15 and the sliding groove 25 and the cooperation between the supporting boss 14 and the supporting groove 24 .

[0046] When the horizontal posture is switched to the folded posture, the front plate 1 first moves horizontally relative to the rear plate 2 (combined with Figure 1 In the direction of the middle arrow), the rotating shaft 15 slides from one end of the sliding groove 25 to the other end;

[0047] After that, the plate 2 rotates, and the front plate 1 rotates with the rotating shaft 15 as the fulcrum. One end of the supporting boss 14 abuts against the track surface 241 and moves along the track surface 241. The abutment between the supporting boss 14 and the track surface 241 bears the load, avoiding shaking when the front plate 1 rotates relative to the rear plate 2, making the posture switching process smooth and controllable.

[0048] Furthermore, a guide shaft 16 is protruded from the support boss 14; the end face of the guide shaft 16 abuts against the groove surface of the support groove 24; when the front plate 1 rotates, it plays an auxiliary supporting role to prevent lateral movement of the front plate 1 when it rotates relative to the rear plate 2.

[0049] Furthermore, a stopper 242 is fixed within the support groove 24, creating a clearance space between the rotation axis 15 and the guide axis 16. When the front panel 1 and rear panel 2 are folded, the stopper 242 penetrates the clearance space, restricting the support boss 14 to rotation only about the rotation axis 15 and preventing horizontal movement, thereby limiting the horizontal movement of the front panel 1. To restore the front panel 1 and rear panel 2 from the folded state to a horizontal state, the front panel 1 first rotates to a horizontal position and then moves horizontally to restore the position.

[0050] More preferably, both ends of the sliding groove 25 are provided with a fulcrum hole 251 , so as to facilitate the rotation of the rotating shaft 15 at the fulcrum hole 251 .

[0051] See also Figure 2 As an embodiment of a foldable shelf assembly, both the front panel 1 and the rear panel 2 are provided with frame-shaped holes, within which are mounted shelf panels 3. Shelf panels 3 are removable, creating a vertical clearance. Users can remove shelf panels 3 from the front panel 1 and / or rear panel 2 depending on the location of items underneath. Shelf panels 3 in this embodiment are preferably glass.

[0052] More preferably, a slot 11 for inserting the shelf plate 3 is provided on the side of the frame-shaped hole; a supporting claw 12 for supporting the shelf plate 3 is fixed on the opposite side of the slot 11, so as to facilitate the removal and placement of the shelf plate 3.

[0053] In the foldable shelf assembly of the present invention, when the rear panel 2 rotates upward about the fulcrum, the support boss 14 rotates within the support groove 24, so that the front panel 1 and the rear panel 2 are stacked vertically, thereby forming a clearance in the vertical direction. When the front panel 1 and the rear panel 2 are both in a horizontal position, items can be placed.

[0054] See also Figure 7The present invention also provides a variable-layer storage unit, comprising an inner container 4, wherein the inner container 4 is provided with multiple layers of the foldable shelf assembly; the rear shaft 21 of the shelf assembly is rotatably provided on the side wall of the inner container 4; and the side wall of the inner container 4 is further fixed with a support strip 5 and a pressure plate 51;

[0055] Combine Figure 9 , users can choose to fold up the shelf components on the upper layer according to the height of the items stored on a certain layer, so that the items can be placed smoothly.

[0056] The utility model also provides a refrigerator comprising at least one variable-layer storage unit.

[0057] In summary, the present invention provides a foldable shelf assembly. When the rear panel rotates upward around the fulcrum, the supporting boss rotates in the supporting groove, so that the front panel and the rear panel are stacked vertically, thereby forming an avoidance in the vertical direction. When the front panel and the rear panel are both in a horizontal position, items can be placed. The present invention also provides a variable layer distance storage unit. According to the height of the items stored on a certain layer, the shelf assembly on the upper layer can be folded up, so that the items can be placed smoothly.

[0058] The utility model also provides a refrigerator comprising at least one variable-layer storage unit.

[0059] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
