[0027] like Figures 1 to 6 The refrigerator door structure shown includes a door body 1, a locking structure 2 for locking it onto the refrigerator, an insulation cavity 3 with openings at the top and bottom, and an end cap assembly for covering the openings of the insulation cavity 3. The end cap assembly includes a decorative strip 41 and connecting seats 42 detachably connected to the left and right ends of the decorative strip 41. At least one end of the connecting seat 42 has a connecting structure 421 for rotatably connecting it to the refrigerator. The upper and lower parts of the door body 1 have a horizontal insert 51 and a vertical insert 52 extending into the insulation cavity 3. The decorative strip 41 has a first slot 411 for inserting the horizontal insert 51 to connect it to the door body 1, and the connecting seat 42 has a second slot 423 for inserting the vertical insert 52 to connect it to the door body 1.
[0028] This design improves the overall insulation performance of the refrigerator by setting up an open, top-and-bottom insulation cavity 3 and using an end cap assembly to cover the openings. The end cap assembly includes a separately manufactured decorative strip 41 and a connecting seat 42. This modular design allows for the installation of decorative strips 41 in different colors or patterns to meet users' personalized needs. The door body 1 is equipped with a locking structure 2 for fixing it to the refrigerator. At the same time, at least one end of the connecting seat 42 is equipped with a connecting structure 421 for rotating and connecting to the refrigerator, thus ensuring the stability of the door when opening and closing and reducing wear or loosening caused by frequent use. The horizontal insert 51 and the vertical insert 52, in conjunction with the first slot 411 on the decorative strip 41 and the second slot 423 on the connecting seat 42, not only simplify the assembly process but also make full use of the space within the insulation cavity 3, making the structure compact and not bulky, thus improving the overall aesthetics.
[0029] Specifically, the connecting structure 421 can be a circular blind hole for inserting the refrigerator door hinge, or it can be a hinge shaft that rotates with the refrigerator. The horizontal insert 51 is press-fitted with the first slot 411, and the vertical insert 52 is press-fitted with the second slot 423. Alternatively, foam material can be used to make the decorative strip 41 more securely attached to the door body 1.
[0030] Furthermore, the second slot 423 is L-shaped, and the end of the transverse insert 51 is inserted into the second slot 423. The transverse insert 51 and the second slot 423 are interference-fitted. Of course, foam material can also be used to make the connecting seat 42 more securely connected to the door body 1 and the decorative strip 41.
[0031] In one embodiment, the decorative strip 41 or the main body 1 of the door is provided with a first clearance opening 412. The locking structure 2 includes a locking seat 21, on which a pin 22 that can pass through the first clearance opening 412 is movably connected. A handle 23 that can drive the pin 22 into the locking seat 21 when rotated is also rotatably connected. A return spring 24 that can return the pin 22 to its original position and extend it out of the first clearance opening 412 is also provided between the pin 22 and the locking seat 21. The locking seat 21 can be connected to the main body 1 by other connection methods such as adhesive or threaded fasteners.
[0032] Specifically, the locking base 21 has two pins 22 arranged side by side, and the handle 23 has a lever 231 that can press the pins 22 when rotated. The pins 22 have a first inclined surface on the side near the lever 231, and the lever 231 has a second inclined surface that cooperates with the first inclined surface. The handle 23 is rotatably connected to the locking base 21 via a pivot.
[0033] In one embodiment, the decorative strip 41 has insertion holes 413 on both the left and right sides, and the connecting seat 42 has a plug block 422 that can be inserted into the insertion hole 413. Furthermore, the plug block 422 can be interference-fitted with the insertion hole 413, or the plug block 422 can be connected to the decorative strip 41 by foam material or other connection methods.
[0034] In one embodiment, the door body 1 includes an inner baffle 11 and a shell 12 connected to the inner baffle 11. The inner baffle 11, the shell 12, and the upper and lower end cap assemblies together enclose a heat insulation cavity 3. The heat insulation cavity 3 can be filled with heat insulation material to further insulate against temperature. The shell 12 can be connected to the inner baffle 11 by adhesive bonding or other connection methods such as threaded fasteners.
[0035] Furthermore, the locking structure 2 is located on the inner side of the back plate 121, and the back plate 121 has a second clearance opening 123 for avoiding the handle 23. This prevents the locking structure 2 from protruding from the outer side of the back plate 121, thus making it more aesthetically pleasing.
[0036] In one embodiment, a shelf 6 for placing items is provided on the inner side of the door body 1. Specifically, a shelf 6 for placing items is provided on the inner side of the inner baffle 11.
[0037] In one embodiment, the transverse insert 51 is formed by bending the back plate 121 towards the insulation cavity 3, and the longitudinal insert 52 is formed by bending the side plate 122 towards the insulation cavity 3. This integrated design reduces the need for additional connectors, making the door structure more robust. The bending process not only increases the rigidity of the components themselves but also improves the stability of the overall structure, reducing deformation or damage caused by external forces. The bent inserts match their corresponding slots, enabling quick and precise assembly.
