[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0036] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0039] This invention provides, in one aspect, the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8A refrigerator door with a resilient self-locking door shelf is shown, comprising: a refrigerator door 1, at least one door shelf 2, and at least one resilient hook 3. The door shelf 2 is detachably connected to the refrigerator door 1; the resilient hook 3 is disposed on the door shelf 2; the resilient hook 3 includes a hook body 31, a spring piece 32, and a limiting block 33. The hook body 31 is disposed on the door shelf 2, and both the spring piece 32 and the limiting block 33 are disposed on the hook body 31. The spring piece 32 has a protrusion 321; a limiting component 11 matching the resilient hook 3 is provided on the refrigerator door 1 at the position corresponding to each resilient hook 3; the resilient hook 3 is snapped together with the limiting component 11 via the protrusion 321, thereby allowing the door shelf 2 to be detachably connected to the refrigerator door 1.

[0040] It should be noted that existing refrigerator door shelves are usually fixed by adhesive tape or by ribs. This method of fixing makes it inconvenient to disassemble and assemble the refrigerator door shelf, and the adhesive strength of the tape will decrease or the ribs will loosen after repeated disassembly and assembly. Alternatively, refrigerator door shelves are fixed with non-elastic buckles. However, there is a gap between the refrigerator door shelf and the refrigerator door. When the user opens and closes the door, the refrigerator door shelf will swing and make noise. Nowadays, there is a type of refrigerator door shelf on the market that is fixed with elastic buckles. However, when removing the refrigerator door shelf 2, you have to pinch the buckle by hand to remove the door shelf 2. The operation is relatively troublesome, and the buckle structure usually protrudes, affecting the appearance.

[0041] The elastic lug 3 of this invention is connected to the limiting component 11 by a protrusion 321, so that the door shelf 2 can be detachably connected to the refrigerator door 1. During assembly, the user only needs to apply a downward force to the door shelf 2, so that the spring piece 32 and the protrusion 321 are engaged with the limiting component 11. Under the action of gravity, the protrusion 321 always abuts against the limiting component 11. When it is necessary to remove the door shelf 2, the user only needs to lift the door shelf 2 upward, so that the protrusion 321 is disengaged from the limiting component 11, thereby achieving the effect of quick assembly and disassembly of the door shelf 2.

[0042] Furthermore, such as Figure 1 As shown, the limiting component 11 includes a first anti-sloping boss 111 and a second anti-sloping boss 112; wherein, the first anti-sloping boss 111 is located on the refrigerator door 1 at the position corresponding to the spring piece 32; the second anti-sloping boss 112 is located on the refrigerator door 1 at the position corresponding to the limiting block 33; a gap is maintained between the first anti-sloping boss 111 and the second anti-sloping boss 112, and the protrusion 321 abuts against the first anti-sloping boss 111 so that the door shelf 2 can be detachably connected to the refrigerator door 1.

[0043] It should be noted that a gap is maintained between the first anti-sloping boss 111 and the second anti-sloping boss 112. The elastic hook 3 passes through the channel formed by the gap between the first anti-sloping boss 111 and the second anti-sloping boss 112, and the elastic hook 3 is fastened to the limiting component 11 by the abutment of the protrusion 321 against the first anti-sloping boss 111.

[0044] Furthermore, such as Figure 1 As shown, the end of the second anti-sloping boss 112 near the limiting block 33 is tilted clockwise, and the ends of the limiting block 33 and the ear body 31 near the second anti-sloping boss 112 are tilted clockwise. The tilt angle of the second anti-sloping boss 112 is the same as the tilt angle of the limiting block 33.

[0045] It should be noted that, as Figure 7 , Figure 8 As shown, the spring piece 32 is tilted clockwise, and under the action of gravity, the protrusion 321 on the spring piece 32 always abuts against the first anti-tilt boss 111. This ensures that the door shelf 2 is fastened to the door inner liner 13 and will not slip off. The slope of the inclined surface of the elastic lug 3 spring piece 32 is the same as the slope of the inclined surface of the first anti-tilt boss 111 on the door inner liner 13, so that the two match each other. The slope of both is preferably 3°. The first step on the door shelf 2 matches the two supporting parts 14 on the door inner liner 13, so that the door shelf 2 does not wobble. During the assembly process, the assembly is easy at the beginning, and at the end, the inertial elastic lug 3 spring piece 32 always abuts against the first anti-tilt boss 111 on the door inner liner 13, so that the door shelf 2 is assembled very tightly and does not wobble.

[0046] Furthermore, the protrusion 321 is disposed at the end of the spring piece 32 away from the lug body 31, and the protrusion 321 is disposed on the side of the spring piece 32 close to the first anti-sloping protrusion 111.

[0047] In addition, the spring 32 and the limiting block 33 are both located below the lug body 31.

[0048] Furthermore, the end of the limiting block 33 is provided with a limiting part 331, which extends along the direction of the spring piece 32, and a gap is maintained between the limiting part 331 and the spring piece 32.

[0049] Understandably, maintaining a gap between the limiting part 331 and the spring piece 32 allows the spring piece 32 a certain reasonable range of motion. This allows the spring piece 32 sufficient bending space, ensuring that the elastic lug 3 can smoothly pass through the channel formed between the first anti-sloping boss 111 and the second anti-sloping boss 112.

[0050] Furthermore, such as Figure 5 As shown, a notch A is provided between the spring piece 32 and the side wall of the door shelf 2, and the spring piece 32 and the hanging ear body 31 form an elastic structure.

[0051] It is understandable that, such as Figures 4-8 As shown, by setting notch A, the spring piece 32 can have a certain range of free movement. Furthermore, the elastic lug 3 is integrally formed with the door shelf 2. Both the elastic lug 3 and the door shelf 2 are made of plastic, so the spring piece 32 has a certain degree of elasticity. Under no external force, the distance between the spring piece 32 and the limiting block 33 is greater than the distance between the first anti-sloping boss 111 and the second anti-sloping boss 112. Therefore, during the installation of the door shelf 2 into the door inner liner 13, the elastic lug 3 needs to pass through the channel formed between the first anti-sloping boss 111 and the second anti-sloping boss 112. The elastic lug 3 is squeezed by the first anti-sloping boss 111 and the second anti-sloping boss 112, and the spring piece 32 contracts, allowing the elastic lug 3 to smoothly enter the channel formed between the first anti-sloping boss 111 and the second anti-sloping boss 112. After the elastic lug 3 enters the matching position, due to the elasticity of the spring piece 32, the protrusion 321 is pushed forward and abuts against the first anti-sloping boss 111. At this point, the door shelf 2 is firmly secured to the inner door liner 13 by the protrusion 321.

[0052] Similarly, when it is necessary to remove the door shelf 2 from the inner door liner 13, simply lift the door shelf 2 upwards to disengage the spring piece 32 from the first anti-sloping boss 111.

[0053] Furthermore, such as Figure 4 and Figure 5 As shown, a groove 311 is provided on the ear body 31, and the groove 311 extends to the outer wall of the door shelf 2.

[0054] It is understandable that, while ensuring the structural strength of the ear loop body 31, opening grooves 311 on the ear loop body 31 can reduce unnecessary structural materials and lower production costs.

[0055] Furthermore, the refrigerator door 1 includes a door shell 12, a door liner 13, and at least two support parts 14. The door liner 13 is disposed on the door shell 12, and the door liner 13 has a first receiving groove 131. The two support parts 14 are respectively symmetrically disposed on the inner side wall of the door liner 13. The limiting component 11 is disposed on the side wall of the support part 14.

[0056] It should be noted that, as Figure 3 , Figure 4 As shown, the first receiving groove 131 is used to receive the door shelf 2, and two supporting parts 14 are respectively arranged on the left and right sides of the door inner liner 13. Two limiting components 11 are symmetrically arranged on the side walls of the two supporting parts 14. The door shelf 2 is supported by the two supporting parts 14, which makes the door shelf 2 more stably connected to the door inner liner 13. In addition, the two supporting parts 14 can form a limiting structure to prevent the door shelf 2 from swaying left and right.

[0057] Furthermore, the side wall of the door shelf 2 is provided with at least two symmetrical first step portions 21, and a second step portion 22 is provided on the door shelf 2 near the first step portion 21. The elastic hanging ear 3 is provided on the second step portion 22, and the first step portion 21 is matched and connected with the support portion 14.

[0058] Understandably, the first step portion 21 matches the supporting portion 14, preventing the door shelf 2 from wobbling left and right within the door inner liner 13, thus improving the user experience. The limiting component 11, composed of the first anti-sloping boss 111 and the second anti-sloping boss 112, matches and connects with the second step portion 22, allowing the elastic hook 3 to be precisely fastened within the gap between the first anti-sloping boss 111 and the second anti-sloping boss 112. Furthermore, it ensures that the protrusion 321 on the spring piece 32 precisely abuts against the first anti-sloping boss 111. This allows the door shelf 2 to be stably fastened onto the door inner liner 13.

[0059] Furthermore, the limiting block 33 is connected to the door shelf 2, the elastic hanging ear 3 is integrally formed with the door shelf 2, and the door shelf 2 is provided with a second receiving groove 23.

[0060] Understandably, the second container 23 is mainly used to hold tableware, food ingredients and other items.

[0061] In another aspect, the present invention provides a refrigerator door including a refrigerator door with an elastic self-locking door shelf as described in any of the first aspects. The user can flexibly install and remove the door shelf 2. When installing the door shelf 2, the user only needs to apply a downward force to the door shelf 2, causing the spring piece 32 and the protrusion 321 to engage with the limiting component 11. Under the action of gravity, the protrusion 321 always abuts against the limiting component 11. When removing the door shelf 2, the user only needs to lift the door shelf 2 upwards, causing the protrusion 321 to disengage from the limiting component 11, thereby achieving the effect of quick installation and removal of the door shelf 2. This improves the user experience when using the refrigerator.

[0062] In summary, the present invention has the following beneficial effects: A refrigerator door 1 with an elastic self-locking door shelf 2 includes: a refrigerator door 1; at least one door shelf 2. The door shelf 2 is detachably connected to the refrigerator door 1; at least one elastic hanging ear 3 is provided on the door shelf 2; wherein, the elastic hanging ear 3 includes a hanging ear body 31, a spring piece 32 and a limiting block 33, the hanging ear body 31 is provided on the door shelf 2, the spring piece 32 and the limiting block 33 are both provided on the hanging ear body 31, and the spring piece 32 is provided with a protrusion 321; a limiting component 11 matching the elastic hanging ear 3 is provided on the refrigerator door 1 at the position corresponding to each elastic hanging ear 3; the elastic hanging ear 3 is snapped together with the limiting component 11 through the protrusion 321, so that the door shelf 2 is detachably connected to the refrigerator door 1. During assembly, the user only needs to apply a downward force to the door shelf 2, causing the spring piece 32 and the protrusion 321 to engage with the limiting component 11. Under the action of gravity, the protrusion 321 always abuts against the limiting component 11. During disassembly, the user only needs to lift the door shelf 2 upwards, causing the protrusion 321 to disengage from the limiting component 11, thereby achieving the effect of quick assembly and disassembly of the door shelf 2.

[0063] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
