[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0022] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", and "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0023] As Figures 1 to 2As shown in the figure, a preferred embodiment of the present utility model provides a refrigerator storage box, which includes a housing 1 and a sealing cover plate assembly.

[0024] The housing 1 is fixedly installed in the storage compartment of the refrigerator. The housing 1 is box-shaped and has an open top for placing and taking items. On the left and right sides of the top opening of the housing 1, there is respectively provided a chute 2, and the two chutes 2 are both arranged along the front and back direction of the housing 1, and the lengths of the two chutes 2 are both equal to the front and back length of the housing 1.

[0025] The sealing cover plate assembly includes a soft cover plate 3 and a hard cover plate 4. The soft cover plate 3 is honeycomb-shaped and can be freely stretched. In addition, the honeycomb core material is made of spunlace non-woven polyester fiber, which has the effects of waterproof and heat preservation. One side of the soft cover plate 3 is fixedly connected to the outer wall of the rear side plate of the housing 1, and the opposite side is fixedly connected to one side of the hard cover plate 4.

[0026] On the bottom surface of the hard cover plate 4, two groups of pulley sets are arranged at intervals left and right, and correspond to the two chutes 2 at the top opening of the housing 1 one by one. Each group of pulley sets includes at least two pulleys 5 arranged at intervals front and back. In this embodiment, preferably two pulleys 5 are provided, and each pulley 5 is placed in the corresponding chute 2 to form a sliding connection.

[0027] Sliding the hard cover plate 4 forward can stretch the soft cover plate 3. When the hard cover plate 4 slides to a suitable position, the soft cover plate 3 and the hard cover plate 4 can jointly seal the top opening of the housing 1. Sliding the hard cover plate 4 backward can shorten the soft cover plate 3 to open the top opening of the housing 1.

[0028] Furthermore, driving devices are respectively arranged on the left and right sides of the housing 1 for driving the hard cover plate 4 to slide back and forth.

[0029] The two sets of driving devices have the same structure. Specifically, the driving device includes a motor 6, a gear 7 and a rack 8. The motor 6 is fixedly installed on the outer wall of the housing 1 through a bracket and is located at the middle position in the front and back of the housing 1. The output shaft of the motor 6 is in transmission connection with the gear 7. The length of the rack 8 is equal to the front and back length of the hard cover plate 4. The rack 8 is arranged along the front and back direction of the housing 1 and is fixedly installed at the position of the outer edge bottom surface of the hard cover plate 4. The gear 7 is meshed with the rack 8.

[0030] This driving device can be linked with the refrigerator door body. When the user opens the refrigerator door body, the top opening of the housing 1 automatically opens. When the user closes the refrigerator door body, the top opening of the housing 1 automatically closes. Of course, the realization of the above linkage function can refer to the existing technology and will not be elaborated here.

[0031] In summary, a refrigerator storage box described in the embodiment of the present utility model can automatically open and close the storage box, has a high degree of intelligence and good user experience. In addition, it has good sealing performance and has the effects of waterproof and heat preservation.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
