The mother refrigerator 10 has the complete functions of a household refrigerator 1, including functions such as freezing, refrigeration and soft freezing, and at the same time adds an interface (or a wireless charging module) to provide a charging function for the sub-refrigerator 20. The bottom of the sub-refrigerator 20 has a wheel structure (universal wheel), a wireless communication module, a charging interface 11 (wired or wireless), a rechargeable battery 22 and a modular warehouse. The sub-refrigerator 20 can be used independently or as a whole with the mother refrigerator 10. When the sub-refrigerator 20 and the mother refrigerator 10 are integrated, they can be used as an integral refrigerator 1. The sub-refrigerator 20 has the same or similar storage and preservation functions as the mother refrigerator 10, as an extension of the mother refrigerator 10. The sub-refrigerator 20 can also be moved to the destination by voice or wireless control. For example, the sub-refrigerator 20 includes a freezer and a refrigerator. When the sub-refrigerator 20 and the mother refrigerator 10 are in a separate mode, the sub-refrigerator 20 is powered by a battery 22 and can be moved manually. When the mother refrigerator 10 is charging the sub-refrigerator 20, the mother refrigerator 10 cools the sub-refrigerator 20 and charges the battery 22 in the sub-refrigerator 20 at the same time. When the sub-refrigerator 20 is low on power, it automatically or manually returns to the mother refrigerator 10 for charging, or it can use the backup battery 22. After replacing the battery 22, the storage function is maintained. The sub-refrigerator 20 as a whole can be moved outdoors, which is more portable.

The second transverse partition 16 is horizontally disposed between the third accommodating cavity 14 and the fourth accommodating cavity 15; the second longitudinal partition 17 is vertically disposed in the fourth accommodating cavity 15 to assist in supporting the second transverse partition 16.

[0065] like Figure 1 As shown, the periphery of the second transverse partition plate 16 is fixedly connected to the inner wall of the mother refrigerator 10, dividing the mother refrigerator 10 into a third storage space and a fourth storage space. The second longitudinal partition plate 17 is vertically arranged in the fourth storage cavity 15, and the upper end of the second longitudinal partition plate 17 abuts against the second transverse partition plate 16 to assist in supporting the second transverse partition plate 16. The second longitudinal partition plate 17 divides the fourth storage cavity 15 into two sub-spaces in the left and right directions for accommodating a plurality of first bins 12.

[0066] In some embodiments, the second transverse partition plate 16 is further disposed in the fourth accommodating chamber 15 to divide the fourth accommodating chamber 15 into a plurality of sub-spaces in the vertical direction for accommodating a plurality of first storage bodies 12 .

[0067] Optionally, at least part of the first warehouse body 12 and the second warehouse body 23 are heat-insulating warehouse bodies.

[0068] The first warehouse body 12 and the second warehouse body 23 are both detachable warehouse bodies. The first warehouse body 12 and the second warehouse body 23 are set as detachable warehouse bodies and are set as heat-insulating warehouse bodies. The first warehouse body 12 and the second warehouse body 23 can be taken out separately for easy carrying.

[0069] Optionally, the refrigerator 1 further includes an elastic connection structure 18. The elastic connection structure 18 is disposed on the side wall of the mother refrigerator 10. When the sub-refrigerator 20 is connected to the mother refrigerator 10 for charging via the charging interface 11 and the adapter interface 21, the elastic connection structure 18 contacts the side wall of the sub-refrigerator 20. The corresponding elastic connection structure 18 presses the sub-refrigerator 20 to trigger the elastic connection structure 18 to pop out and push the sub-refrigerator 20 to be separated from the mother refrigerator 10.

[0070] like Figures 1 to 5 As shown, a charging interface 11 is provided on the side wall of the mother refrigerator 10, and an adapter interface 21 is provided on the side wall of the sub-refrigerator 20 corresponding to the charging interface 11. An elastic connecting structure 18 is provided around the charging interface 11 for fixing the sub-refrigerator 20 to the mother refrigerator 10 to prevent an unstable connection between the charging interface 11 and the adapter interface 21.

[0071] Optionally, the elastic connection structure 18 includes a top plate 181, an elastic member 182 and an elastic buckle 183. The top plate 181 is arranged on the side wall of the mother refrigerator 10 corresponding to the side wall of the sub-refrigerator 20; the elastic member 182 connects the top plate 181 and the side wall of the mother refrigerator 10; the elastic buckle 183 movably connects the top plate 181 and the side wall of the mother refrigerator 10, and the top plate 181 is pressed to open the elastic buckle 183 so that the elastic member 182 pushes the sub-refrigerator 20 out.

[0072] like Figure 2 and Figure 3As shown, the top plate 181 is annularly arranged around the periphery of the charging port 11, and one side of the top plate 181 is connected to the side wall of the mother refrigerator 10 through an elastic member 182. The side wall of the mother refrigerator 10 is also provided with a second hook 1832 and a third hook 1833, and a plug hole 1834 is provided between the second hook 1832 and the third hook 1833. A first hook 1831 is provided on one side of the top plate 181 corresponding to the plug hole 1834. The first hook 1831 is made of rubber material. The top plate 181 is pressed horizontally toward the mother refrigerator 10 to compress the elastic member 182, and at the same time, the first hook 1831 is inserted from the plug hole 1834 to between the second hook 1832 and the third hook 1833. When the sub-refrigerator 20 needs to be connected to the main refrigerator 10 for charging, press the top plate 181 horizontally, and a first click sound will be emitted when the first hook 1831 is engaged with the second hook 1832. At this time, stop pressing the top plate 181, and the first hook 1831 and the second hook 1832 will be engaged, connecting the sub-refrigerator 20 to the main refrigerator 10, keeping the sub-refrigerator 20 in the charging state. The depth of the charging interface 11 of the mother refrigerator 10 is greater than the length of the matching interface of the sub-refrigerator 20, so that when the sub-refrigerator 20 needs to be separated from the mother refrigerator 10, the top plate 181 is pressed horizontally again to make the outer side of the first hook 1831 contact the third hook 1833. At this time, the matching interface 21 is pressed and inserted deeper into the charging interface 11, and the third hook 1833 squeezes the first hook 1831 to reduce the hook angle of the first hook 1831. When the hook angle of the first hook 1831 is reduced, the first hook 1831 and the second hook 1832 cannot be hooked with each other. At this time, the pressing of the top plate 181 is released. The first hook 1831 is a rubber hook and cannot restore the hook angle of the first hook 1831 in the first time. At this time, the top plate 181 loses the hook connection between the first hook 1831 and the second hook 1832, and pops outward under the elastic force of the elastic member 182 to push the sub-refrigerator 20 out to separate from the mother refrigerator 10. After the sub-refrigerator 20 leaves the main refrigerator 10, the hook angle of the first hook 1831 gradually returns to its original hook angle, so that when the sub-refrigerator 20 is charged again, pressing the top plate 181 can make the first hook 1831 hook with the second hook 1832 again.

[0073] In some embodiments, the elastic member 182 includes one or more of a spring, a spring washer, and a rubber washer.

[0074] In some embodiments, the mother refrigerator 10 further includes a spring groove, which is horizontally arranged on the side wall of the mother refrigerator 10 and is used to install the elastic member 182 .

[0075] like Figure 2 As shown, one end of the spring is arranged in the spring groove, and the other end protrudes horizontally out of the spring groove and is fixedly connected to the top plate 181.

[0076] In some embodiments, there are two elastic buckles 183 , which are symmetrically arranged at the two ends of the top plate 181 in the up and down directions.

[0077] In some embodiments, there are multiple elastic snap-ons, and the multiple elastic snap-ons are evenly distributed around the top plate 181 with the charging port 11 as the center.

[0078] Optionally, a moving wheel 29 is provided at the bottom of the sub-refrigerator 20 .

[0079] like Figure 1 As shown, a moving wheel 29 is provided at the bottom of the sub-refrigerator 20. The moving wheel 29 can be a one-way wheel or a universal wheel to facilitate the control of the movement of the sub-refrigerator 20.
