[0056] Figure 4 ​As shown, the embodiment first provides a vertical beam assembly 20 for a refrigerator door body 130, which comprises: a vertical beam body 200, comprising a bottom shell 210 and a cover plate 220, the cover plate 220 being covered on the bottom shell 210 to form a foaming space 230 filled with foaming material, wherein the bottom shell 210 is provided with a plurality of accommodating cavities 240 along the longitudinal direction of the vertical beam assembly 20 respectively near one side of the refrigerator door body 130, and the plurality of accommodating cavities 240 are further provided with a plurality of sealing covers 250 respectively towards one side of the cover plate 220, the plurality of sealing covers 250 corresponding to the plurality of accommodating cavities 240 respectively to close the openings of the plurality of accommodating cavities 240 to the foaming space 230; a hinge assembly, comprising a plurality of hinges 300 respectively installed in the plurality of accommodating cavities 240 to rotatably connect the vertical beam body 200 to the refrigerator door body 130.

[0057] The scheme of the embodiment simplifies the structure of the vertical beam body 200 and reduces the production cost and installation process difficulty of the vertical beam assembly 20 by setting the vertical beam body 200 as a two-piece structure (i.e. composed of the bottom shell 210 and the cover plate 220) and setting the cover plate 220 to cover the bottom shell 210 to form a foaming space 230 filled with foaming material, thereby ensuring the heat insulation performance of the vertical beam assembly 20.

[0058] Further, the scheme of the embodiment ensures the normal flipping of the vertical beam body 200 by setting the plurality of accommodating cavities 240 on the bottom shell 210 and setting the corresponding hinges 300 in the plurality of accommodating cavities 240 respectively to rotatably connect the vertical beam body 200 to the refrigerator door body 130.

[0059] Further, the scheme of the embodiment ensures the normal operation of the hinge assembly and the normal flipping of the vertical beam assembly 20 by setting each accommodating cavity 240 to have a corresponding sealing cover 250 towards one side of the cover plate 220 to close the opening of the accommodating cavity 240 to the foaming space 230, thereby avoiding the foaming material flowing from the foaming space 230 into the accommodating cavity 240 to interfere with the hinge 300 installed in the accommodating cavity 240.

[0060] As shown, the scheme of the embodiment sets two accommodating cavities 240 on the bottom shell 210 to be distributed up and down along the longitudinal direction of the vertical beam assembly 20 and sets two hinges 300 corresponding to the two accommodating cavities 240 respectively to be installed in the two accommodating cavities 240. The two hinges 300 act together to ensure the smooth flipping of the vertical beam assembly 20.

[0061] In some other embodiments, three accommodating cavities 240 and three hinges 300 can be arranged on the bottom shell 210, or four accommodating cavities 240 and four hinges 300 can be arranged on the bottom shell 210. The more the number of the hinges 300, the more stable the vertical beam assembly 20 is installed on the door body 130, but the accommodating cavities 240 occupy more space in the vertical beam body 200 (i.e. the foaming space 230 is correspondingly reduced, thereby reducing the heat insulation performance of the vertical beam assembly 20), and the production cost is correspondingly increased. Therefore, the specific number of the accommodating cavities 240 and the hinges 300 can be set according to the length of the vertical beam assembly 20 and the production cost, etc.

[0062] As shown in FIG. 6, both ends of each of the plurality of accommodating cavities 240 are provided with a positioning portion 241, and both ends of each of the plurality of sealing covers 250 are provided with a fixing portion 251 corresponding to the positioning portion 241. The positioning portion 241 and the fixing portion 251 are matched one by one, and are used for positioning and fixing the sealing cover 250. Figures 1-7

[0063] In the scheme of the embodiment, the positioning portion 241 is arranged at both ends of the accommodating cavity 240, and the fixing portion 251 corresponding to the positioning portion 241 is arranged at both ends of the sealing cover 250. The fixing portion 251 and the positioning portion 241 are correspondingly matched one by one, thereby realizing the positioning of the sealing cover 250. At the same time, the positioning portion 241 and the fixing portion 251 are correspondingly matched one by one, and are also used for fixing the sealing cover 250. In the scheme of the embodiment, the positioning portion 241 and the fixing portion 251 are respectively provided with round holes, and a fastening screw (not shown in the figure) passes through the round holes on the fixing portion 251 and the positioning portion 241, thereby fixing the positioning portion 241 and the fixing portion 251 together. It can be understood that the fixing portion 251 and the positioning portion 241 can also be fixed together by using other fasteners, such as fastening studs, etc. In some embodiments, the positioning portion 241 and the fixing portion 251 can also be fixed together by using adhesives such as glue.

[0064] In some other embodiments, the fixing portion 251 can be provided with a hole, and the positioning portion 241 can be arranged as a columnar body matched with the shape and size of the hole on the fixing portion 251, so that the positioning portion 241 can be inserted into the hole of the fixing portion 251, thereby realizing the positioning and fixing of the sealing cover 250.

[0065] In some other embodiments, the fixing portion 251 can be provided with a protrusion, and the positioning portion 241 can be provided with a notch matched with the shape and size of the protrusion on the fixing portion 251, so that the protrusion on the fixing portion 251 can be embedded into the notch on the positioning portion 241, thereby realizing the positioning and fixing of the sealing cover 250.

[0066] As shown in FIG. 6, both ends of each of the plurality of accommodating cavities 240 are provided with a positioning portion 241, and both ends of each of the plurality of sealing covers 250 are provided with a fixing portion 251 corresponding to the positioning portion 241. The positioning portion 241 and the fixing portion 251 are matched one by one, and are used for positioning and fixing the sealing cover 250. Figures 4-6 ​As shown, one end of one of the multiple receiving cavities 240 is provided with a through hole 242 for passing through a line 244 leading to the interior of the vertical beam body 200; a sealing ring 243 is also provided at the through hole 242, and the sealing ring 243 is snapped between the sealing cover 250 and the bottom shell 210 to seal the gap between the line 244 and the through hole 242.

[0067] In some preferred embodiments, heating wires or sensors may also be installed inside the vertical beam body 200. Therefore, the power supply line 244 needs to be introduced from the refrigerator door 130 into the vertical beam body 200 to supply power to the electrical devices inside the vertical beam body 200.

[0068] In this embodiment, by providing a through hole 242 at one end of the receiving cavity 240, the wire 244 can pass through the hinge 300 on the refrigerator door 130 and then through the through hole 242 at the end of the receiving cavity 240 into the vertical beam body 200, thereby enabling power supply to the electrical components inside the vertical beam body 200. This not only improves the safety of the wire 244 installation but also enhances the aesthetics of the vertical beam assembly 20.

[0069] Furthermore, in this embodiment, a sealing ring 243 is provided at the through hole 242 at the end of the receiving cavity 240, through which the wire 244 can pass. The sealing ring 243 is engaged between the sealing cover 250 and the bottom shell 210, thereby sealing the gap between the through hole 242 at the end of the receiving cavity 240 and the wire 244, ensuring the airtightness between the receiving cavity 240 and the foaming space 230, and preventing the foaming material from flowing into the receiving cavity 240 and affecting the normal rotation of the hinge 300 inside the receiving cavity 240. In some preferred embodiments, the sealing ring 243 can be made of an elastic material (e.g., rubber) to better seal the gap between the wire 244 and the through hole 242 of the receiving cavity 240.

[0070] like Figure 5 As shown, among the multiple hinges 300, there is a limiting hinge 310. The limiting hinge 310 includes: a first pivot member 311, which is installed in the receiving cavity 240 and passes through the side wall of the bottom shell 210 and is connected to the refrigerator door 130, wherein the lower end face of the first pivot member 311 is formed as a cam surface; a second pivot member 312, which is slidably disposed below the first pivot member 311 along the longitudinal direction of the vertical beam body 200 and has an upper end face that cooperates with the cam surface of the first pivot member 311; and a spring 313, one end of which abuts against the bottom surface of the second pivot member 312 and the other end of which abuts against the abutment part 245 provided in the receiving cavity 240.

[0071] The abutting part 245 is a half annular protrusion arranged at the bottom end of the accommodating cavity 240, used for abutting against the spring 313, so that the spring 313 can provide elastic force to the second rotating shaft part 312 under compression. In other embodiments, the bottom end of the accommodating cavity 240 can also not be provided with the abutting part 245, so that the spring 313 in the compressed state directly abuts against the bottom end face of the accommodating cavity 240.

[0072] When the door body 130 is opened, the vertical beam assembly 20 will form a certain overturning angle, and the overturning angle will change, which will cause the vertical beam assembly 20 to fail to normally overturn during the closing process of the door body 130, and further cause the refrigerator door body 130 to fail to normally close.

[0073] In the scheme of the embodiment, the lower end face of the first rotating shaft part 311 and the upper end face of the second rotating shaft part 312 located below the first rotating shaft part 311 are wave-shaped cam faces matched with each other. When the first rotating shaft part 311 rotates relative to the vertical beam body 200, it also slides relative to the second rotating shaft part 312 along the cam faces, and further drives the second rotating shaft part 312 to move up and down along the longitudinal direction of the vertical beam body 200.

[0074] In the scheme of the embodiment, the spring 313 is arranged below the second rotating shaft part 312 to exert upward elastic force on the second rotating shaft part 312, so that the second rotating shaft part 312 can move upward, thereby promoting the sliding of the first rotating shaft part 311 relative to the second rotating shaft part 312 along the cam faces, and further promoting the rotation of the first rotating shaft part 311 relative to the vertical beam body 200.

[0075] In the scheme of the embodiment, the cam faces of the first rotating shaft part 311 and the second rotating shaft part 312 and the spring 313 are arranged, so that under the action of the elastic force of the spring 313 and the special shape structure of the cam faces, the first rotating shaft part 311 and the second rotating shaft part 312 will not easily produce relative motion with the rotation of the door body 130 or the accidental touch of the user after the vertical beam assembly 20 is opened, which avoids the change of the overturning angle of the vertical beam assembly 20 after the refrigerator door body 130 is opened, and further ensures the normal opening and closing of the refrigerator door body 130.

[0076] In addition, when the door body 130 of the refrigerator 10 is opened, the second rotating shaft member 312 can provide an assisting force for the relative rotation of the first rotating shaft member 311 under the elastic force of the spring 313 when the cam surfaces of the second rotating shaft member 312 and the first rotating shaft member 311 are not completely matched, so that the vertical beam body 200 is closer to the door body 130. When the door body 130 of the refrigerator 10 is closed, the second rotating shaft member 312 can also provide an assisting force for the relative rotation of the first rotating shaft member 311 under the elastic force of the spring 313 when the cam surfaces of the second rotating shaft member 312 and the first rotating shaft member 311 are not completely matched, so that the vertical beam body 200 is closer to the cabinet 100 of the refrigerator 10.

[0077] The scheme of the embodiment avoids the random flipping of the vertical beam assembly 20 after the door body 130 of the refrigerator is opened, thereby ensuring the normal opening and closing of the door body 130 of the refrigerator.

[0078] As shown in Figure 6 and Figure 4 , the two sides of the cover plate 220 extend towards the bottom shell 210 and are formed with a plurality of buckles 221, and the sidewall of the bottom shell 210 is correspondingly provided with a plurality of protrusions 211, and the plurality of buckles 221 and the plurality of protrusions 211 are matched one by one to fix the cover plate 220 to the bottom shell 210.

[0079] The scheme of the embodiment is that a plurality of buckles 221 are arranged on the cover plate 220, and corresponding protrusions 211 are arranged on the sidewall of the bottom shell 210, and the buckle 221 and the protrusion 211 are buckled together to fix the cover plate 220 to the bottom shell 210.

[0080] In other embodiments, protrusions 211 can also be arranged on the cover plate 220, and corresponding buckles 221 can be arranged on the sidewall of the bottom shell 210 to fix the cover plate 220 and the bottom shell 210 together, and the specific arrangement mode can be arranged according to actual needs.

[0081] Figure 7 is another angle structure schematic view of the vertical beam assembly 20 for the door body 130 of the refrigerator according to an embodiment of the present application. Figure 8 is Figure 9 a partial enlarged view of region E in Figure 8 is Figure 10 a partial enlarged view of region F in Figure 8 is Figure 11 a partial enlarged view of region G in

[0082] In order to better show the structure inside the vertical beam body 200, Figure 8 The cover plate 220 is hidden in the middle.

[0083] The vertical beam assembly 20 for the refrigerator door body 130 further comprises two sealing members 260, which are respectively arranged at the two ends of the vertical beam body 200 and are clamped between the bottom shell 210 and the cover plate 220 to seal the gap between the bottom shell 210 and the cover plate 220.

[0084] The scheme of the embodiment seals the gap between the bottom shell 210 and the cover plate 220 by arranging the sealing member 260 and embedding the sealing member 260 between the end of the cover plate 220 and the end of the bottom shell 210, thereby improving the sealing performance of the vertical beam assembly 20.

[0085] As shown in Figure 8 In the scheme of the embodiment, each sealing member 260 comprises a first plate portion 261 abutting against the end of the bottom shell 210, a second plate portion 262 extending from the first plate portion 261 at one end of the bottom shell 210 and extending outward along the longitudinal direction of the vertical beam body 200, and a clamping groove 263 with an opening facing the cover plate 220 formed in the first plate portion 261, and the two ends of the cover plate 220 are respectively provided with a flange 222 clamped into the clamping groove 263.

[0086] The first plate portion 261 of the sealing member 260 is arranged to abut against the end of the bottom shell 210 to seal the gap between the cover plate 220 and the bottom shell 210. The clamping groove 263 for clamping the flange 222 of the cover plate 220 is further arranged on the first plate portion 261 to position and fix the cover plate 220. When the refrigerator door body 130 is in a closed state, the second plate portion 262 at the two ends of the vertical beam body 200 further seals the gap between the door body 130 and the cabinet 100, thereby improving the sealing effect of the vertical beam assembly 20.

[0087] As shown in Figure 9 The top end of the bottom shell 210 is provided with a guide groove 270 for guiding the overturning of the vertical beam body 200, and the groove wall of the guide groove 270 is provided with spaced apart rib plates 271 connected with the side wall of the bottom shell 210 to improve the strength of the vertical beam body 200.

[0088] The scheme of the embodiment guides the overturning of the vertical beam assembly 20 during the opening and closing of the refrigerator door body 130 by arranging the guide groove 270 at the top end of the bottom shell 210, thereby ensuring the normal opening and closing of the door body 130.

[0089] Further, the scheme of the embodiment improves the strength of the vertical beam body 200 by arranging the ribs 271 at intervals on the outer periphery of the groove wall of the guide groove 270 and arranging the ribs 271 to be connected to the side wall of the bottom shell 210. In addition, the interval arrangement of the plurality of ribs 271 also accelerates the heat dissipation speed of the top end of the bottom shell 210 during the manufacturing process, thereby avoiding material deformation (such as shrinkage) caused by uneven / local slow heat dissipation of the end portion of the bottom shell 210, improving the production quality and reducing the production loss.

[0090] The bottom end of the bottom shell 210 is also provided with a pouring hole 231 for injecting foaming material into the foaming space 230.

[0091] The scheme of the embodiment arranges the pouring hole 231 at the bottom end of the bottom shell 210, which not only facilitates the injection of foaming material into the foaming space 230, but also has an attractive structure, thereby improving the attractiveness of the vertical beam assembly 20.

[0092] In some preferred embodiments, the vertical beam assembly 20 adopts a closed mold foaming manner. After the cover plate 220 and the bottom shell 210 are buckled together to form a sealed foaming space 230, foaming material is injected into the foaming space 230 through the pouring hole 231 at the bottom end of the bottom shell 210, thereby ensuring that no overflow occurs during foaming.

[0093] The vertical beam assembly 20 for the refrigerator door body 130 also includes an end cover 280 arranged telescopically at the bottom end of the bottom shell 210, and an elastic member 281 arranged between the bottom shell 210 and the end cover 280, one end of which abuts against the end portion of the bottom shell 210 and the other end of which abuts against the end cover 280.

[0094] In some preferred embodiments, the elastic member 281 can be a compression spring for providing the end cover 280 with a downward moving elastic force.
