[0033] First, see Figure 1 and Figure 2The present application provides a shelf assembly 10, including an inner shelf frame 11 and an outer shelf frame 12, the outer shelf frame 12 is provided with a first snap-fit ​​portion 121 and an elastic member 122, the elastic member 122 and the inner shelf frame 11 are in contact with the inner shelf frame, the inner shelf frame 11 is provided with a second snap-fit ​​portion 111, the inner shelf frame 11 and the outer shelf frame 12 jointly define a accommodating cavity 13; the inner shelf frame 11 can movably change its embedded depth in the outer shelf frame 12 to adjust the height of the accommodating cavity 13, when the inner shelf frame 11 moves to the first embedded depth, the second snap-fit ​​portion 111 and the first snap-fit ​​portion 121 are engaged; when the second snap-fit ​​portion 111 and the first snap-fit ​​portion 121 are disengaged, the elastic member 122 is reset to enable the inner shelf frame 11 to move to the second embedded depth, and the first embedded depth is greater than the second embedded depth.

[0034] The shelf assembly 10 provided in the present application has a storage cavity 13 for placing items. When the height of the items to be stored is relatively low, the inner shelf frame 11 can be controlled to move toward the outer shelf frame 12. When the second latch portion 111 and the first latch portion 121 come into contact, they engage, so that the storage cavity 13 has a relatively low height, which allows for the stable storage of relatively low items. When the height of the items to be stored is relatively high, the first latch portion 121 and the second latch portion 111 are controlled to disengage, and the elastic member 122 utilizes its elastic recovery deformation to push the inner shelf frame 11 away from the outer shelf frame 12, so that the storage cavity 13 has a relatively high height, which allows for the stable storage of relatively high items. The shelf assembly 10 provided in the present application can adjust the depth of the inner shelf frame 11 embedded in the outer shelf frame 12 by controlling the engagement of the first latch portion 121 and the second latch portion 111 and utilizing the return of the elastic member 122, thereby adjusting the height of the storage cavity 13 to accommodate items of different heights. The shelf assembly 10 has a simple structure and is easy to use.

[0035] See also Figure 3 The first embedding depth X1 refers to the height of the overlapping portion of the shelf inner frame 11 and the shelf outer frame 12 in the vertical direction when the second locking portion 111 and the first locking portion 121 are locked.

[0036] Accordingly, see Figure 4 The second embedding depth X2 refers to the height of the vertically overlapping portion of the shelf inner frame 11 and the shelf outer frame 12 when the elastic member 122 is reset, where X1>X2. It should be noted that when the second latch portion 111 and the first latch portion 121 are engaged, the elastic member 122 is compressed and elastically deformed. The elastic member 122 possesses elastic potential energy. When the second latch portion 111 and the first latch portion 121 are disengaged, the elastic member 122 releases this elastic potential energy, generating an elastic force toward the shelf inner frame 11. This elastic force is greater than the weight of the shelf inner frame 11, thereby pushing the shelf inner frame 11 away from the shelf outer frame 12.

[0037] It should be noted that when the shelf assembly 10 is used to place items, the inner shelf frame 11 is located inside and above the outer shelf frame 12, and the inner shelf frame 11 is open toward one side of the outer shelf frame 12. The height H of the accommodating cavity 13 is the distance between the top of the inner shelf frame 11 and the bottom of the outer shelf frame 12 in the vertical direction. Specifically, the height of the inner shelf frame 11 is H1, and the height of the outer shelf frame 12 is H2, where H1 ≤ H2. When the second latch portion 111 and the first latch portion 121 are engaged, the height H of the accommodating cavity 13 is H = H1 + H2 - X1; when the elastic member 122 is reset, the height H of the accommodating cavity 13 is H = H1 + H2 - X2. It can be understood that (H1 + H2 - X1) > (H1 + H2 - X2).

[0038] In some embodiments, the elastic member 122 is a spring, and a retaining post 112 is provided on the shelf inner frame 11. The spring is sleeved around the outer periphery of the retaining post 112. It will be appreciated that when the elastic force generated by the elastic member 122 is large, the shelf inner frame 11 will be completely lifted or even released from the spring. Gravity will then cause the shelf inner frame 11 to move downward until it abuts the spring. By sleeved around the outer periphery of the retaining post 112, when the spring is reset and the shelf inner frame 11 moves downward under gravity, the retaining post 112 can be positioned. Furthermore, when the elastic member 122 supports the shelf inner frame 11, the cooperation between the retaining post 112 and the spring prevents the shelf inner frame 11 from completely falling off the shelf outer frame 12 during shaking, thereby improving the stability of the shelf assembly 10.

[0039] In some embodiments, the shelf frame 12 is provided with a mounting groove 123, and the elastic member 122 is located in the mounting groove 123 and fixedly connected to the bottom of the mounting groove 123. In this way, the elastic member 122 can be prevented from completely separating from the shelf frame 12 when resetting.

[0040] In some embodiments, the shelf frame 12 is provided with a mounting slot 123, within which an elastic member 122 is positioned. The elastic member 122 and the mounting slot 123 are detachably connected. After repeated adjustments to the height of the accommodating cavity 13, i.e., after repeated compression and resetting of the elastic member 122, the elastic member 122 may fatigue and lose its elasticity. The elastic member 122 can be removed and replaced with a new one. The cost of the elastic member 122 is relatively low, thereby increasing the utilization rate and service life of the shelf assembly 10 at a low cost.

[0041] In some embodiments, two elastic members 122 are provided, symmetrically positioned on either side of the first latch portion 121. Multiple elastic members 122 enhance the spring force, thereby facilitating movement of the inner shelf frame 11 away from the outer shelf frame 12, increasing the height of the accommodating cavity 13, and supporting the gravity of the inner shelf frame 11. Accordingly, two limiting posts 112 are provided, symmetrically positioned on either side of the second latch portion 111, to engage with the two elastic members 122, respectively.

[0042] In some embodiments, the shelf assembly 10 has a set of first locking portions 121 , second locking portions 111 , and elastic members 122 on both sides along the horizontal direction to ensure that both sides of the accommodating cavity 13 have the same height.

[0043] In some embodiments, a limiting post 112 is provided on the shelf inner frame 11, and an elastic member 122 is sleeved around the outer circumference of the limiting post 112. When the shelf inner frame 11 moves to a first embedding depth, the end of the limiting post 112 away from the shelf inner frame 11 is embedded in the mounting groove 123. It will be understood that when the shelf inner frame 11 is controlled to move toward the shelf outer frame 12, the limiting post 112 simultaneously moves toward the shelf outer frame 12, specifically toward the mounting groove 123, thereby guiding the movement of the shelf inner frame 11 until the second latch portion 111 and the first latch portion 121 are engaged.

[0044] In some embodiments, the sidewalls of the outer shelf frame 12 are provided with a retaining groove 124, and the outer wall of the inner shelf frame 11 is provided with a retaining protrusion 113. The retaining protrusion 113 is located within the retaining groove 124. When the inner shelf frame 11 moves to the second embedding depth, the retaining protrusion 113 and the end of the retaining groove 124 engage with each other, thereby preventing the inner shelf frame 11 and the outer shelf frame 12 from completely separating. It should be noted that the retaining groove 124 is defined along the direction of movement of the inner shelf frame 11. When the inner shelf frame 11 changes its embedding depth within the outer shelf frame 12, the retaining protrusion 113 moves synchronously within the retaining groove 124. When the elastic member 122 is reset, i.e., when the inner shelf frame 11 moves to the second embedding depth, the retaining protrusion 113 and the upper end of the retaining groove 124 engage with each other in a vertical direction, thereby preventing the inner shelf frame 11 from completely separating from the outer shelf frame 12.

[0045] In some embodiments, when the shelf inner frame 11 moves to the first embedding depth, the limiting protrusion 113 and the end of the limiting groove 124 engage with each other. Specifically, when the second latch portion 111 and the first latch portion 121 engage, that is, when the shelf inner frame 11 moves to the first embedding depth, the limiting protrusion 113 and the lower end of the limiting groove 124 in the vertical direction engage with each other, further limiting the engagement and ensuring that the second latch portion 111 and the first latch portion 121 engage with each other.

[0046] It should be noted that the limiting protrusion 113 is located in the lower middle portion of the outer wall of the shelf inner frame 11 . Thus, when the elastic member 122 is reset, the second embedding depth can be made shallower, thereby increasing the height of the accommodating cavity 13 as much as possible to store taller items.

[0047] In some embodiments, a flange 114 is provided on the side of the shelf inner frame 11 away from the shelf outer frame 12, and the second snap-fit ​​portion 111 is provided on the flange 114 and extends in a direction close to the shelf outer frame 12; the first snap-fit ​​portion 121 and the elastic member 122 are provided on the end surface 125 of the shelf outer frame 12 close to the shelf inner frame 11, and the elastic member 122 extends along the movement direction of the shelf inner frame 11.

[0048] In some embodiments, when the shelf inner frame 11 moves to the first embedding depth, the flange 114 abuts against the end face 125 of the shelf outer frame 12. At this time, the first embedding depth X1 = the height H1 of the shelf inner frame 11. In other words, at this time, the height H of the accommodating cavity 13 = the height H2 of the shelf outer frame 12. In this way, the height of the accommodating cavity 13 can be lowered as much as possible to store items of lower height.

[0049] It should be noted that, in this embodiment, the limiting column 112 is arranged on the flange 114 and extends in the direction close to the shelf outer frame 12. The height of the limiting column 112 along the movement direction of the shelf inner frame 11 is less than or equal to the height of the mounting groove 123 to ensure that the limiting column 112 can be fully embedded in the mounting groove 123, so that the flange 114 and the end face 125 of the shelf outer frame 12 are in contact.

[0050] In a second aspect, an embodiment of the present application further provides a refrigerator, which includes the above-mentioned shelf assembly 10.

[0051] In some embodiments, see Figure 5 The refrigerator also includes a door body 20, a shelf assembly 10 is provided on the door body 20, a shelf outer frame 12 is fixedly connected to the door body 20, and a shelf inner frame 11 is movably connected to the shelf outer frame 12 to adjust the height of the accommodating cavity 13, which is suitable for storing items of different heights.

[0052] In some embodiments, multiple shelf assemblies 10 are arranged in parallel and spaced apart on the door body 20. Specifically, during use of the refrigerator, the multiple shelf assemblies 10 are arranged in a vertically spaced manner. The multiple shelf assemblies 10 can fully utilize the space on the door body 20 to store more items.

[0053] In some embodiments, the distance between adjacent shelf assemblies 10 is greater than the height of the shelf inner frame 11. It should be noted that the distance between shelf assemblies 10 refers to the distance between the shelf outer frames 12. The distance between adjacent shelf assemblies 10 is greater than the height H1 of the shelf inner frame 11 to facilitate the movement of the shelf inner frame 11 to change its embedded depth within the shelf outer frame 12, thereby adjusting the height of the accommodating cavity 13.

[0054] In some embodiments, at least one of the heights of the elastic members 122, the inner shelf frames 11, and the outer shelf frames 12 in the multiple shelf assemblies 10 can be different to accommodate storage requirements for items of varying heights. Specifically, elastic members 122 having different lengths when resetting, or inner and outer frames of varying heights can be combined to accommodate a wider range of storage heights.

[0055] In some embodiments, when three or more shelf assemblies 10 are provided on the door body 20, the distances between adjacent shelf assemblies 10 are different. This is advantageous for storing items of different heights. For taller items, they can be placed in a shelf assembly 10 that is farther away from the previous shelf assembly 10.

[0056] The basic concepts have been described above. It will be apparent to those skilled in the art that the detailed disclosure above is merely illustrative and does not limit the present application. Although not explicitly stated herein, those skilled in the art may make various modifications, improvements, and amendments to the present application.
