[0065] Figure 8 This is a schematic diagram of the structure of the upper end cover provided in this application. Fig. 9 for Figure 8 Magnified view of area D in . Fig.10 This is a schematic diagram of the structure of the upper frame provided for this application.

[0066] like Figures 7 to 10 As shown, in some embodiments of the present application, a second clamping portion may be formed on one side of the upper end cover 215 facing the upper frame 211. The second clamping portion is disposed below the first clamping block 2151. A second clamping member group extending toward the upper end cover 215 is formed on the upper frame 211, and the second clamping member group is connected to the second clamping portion to improve the connection stability between the upper end cover 215 and the upper frame 211.

[0067] In some embodiments of the present application, the second clamping portion includes a second clamping groove 2223. In some embodiments, the first clamping groove 2223 can be set as a line extending along the length direction of the upper end cover 215. In other embodiments, a plurality of first clamping grooves 2223 can be provided. The plurality of first clamping grooves 2223 are sequentially distributed along the length direction of the upper end cover 215.

[0068] like Fig. 9 and Fig.10 As shown, the notch of the second card slot 2223 is arranged toward the upper frame 211. The upper slot wall of the second card slot 2223 is provided with a second card block 2153. The lower slot wall of the second card slot 2223 is provided with a third card block 2154. The second card assembly may include a first buckle 2112 and a second buckle 2113. The first buckle 2112 is formed with a hook body portion bent upward. The first buckle 2112 extends into the second card slot 2152 and is engaged and connected with the second card block 2153. The second buckle 2113 is formed with a hook body portion bent downward. The second buckle 2113 extends into the second card slot 2152 and is engaged and connected with the third card block 2154. Through the above connection, it is possible to avoid displacement of the upper end cover 215 and the upper frame 211 in the height direction of the door body 2.

[0069] The upper end cover 215 , the left frame 213 , the lower frame 212 and the right frame 214 can enclose a door cavity, so that the door cavity can be sealed and filled with foam material to achieve the heat preservation and thermal insulation performance of the door body 2 .

[0073] Fig.11 This is a schematic structural diagram of the handle structure provided in this application under the first visual perspective. Fig.12 This is a schematic diagram of the structure of the handle structure provided in this application under the second visual perspective.

[0074] like Figure 3 , Figure 7 , Fig.11 and Fig.12 As shown, in some embodiments of the present application, the door body 2 includes a handle structure 22. A buckle groove 216 is formed on the upper side of the door frame 21 facing away from the box body 1. The handle structure 22 is arranged above the buckle groove 216 and is used to open the door body 2.

[0075] In some embodiments of the present application, the buckle groove 216 is formed on the upper end cover 215, and the handle structure 22 is connected to the upper end cover 215, forming a space suitable for human hand buckling with the buckle groove 216 to open the door body 2. It can be understood that in other embodiments, the buckle groove 216 can be formed on the left frame 213 or the right frame 214, and in this case, the handle structure 22 is connected to the left frame 213 or the right frame 214.

[0076] The handle structure 22 includes a connecting portion 221. The connecting portion 221 is connected to the top of the door frame 21 to fix the handle structure 22 on the upper end cover 215.

[0077] The handle structure 22 includes a handle portion 222. The handle portion 222 is connected to a side of the connection portion 221 away from the box body 1, covers a side of the door frame 21 facing away from the box body 1, and extends into the buckle groove 216 to form a space for human hand buckling.

[0078] A first inclined surface 2221 is formed on the lower part of the handle portion 222 facing the side of the door frame 21. The first inclined surface 2221 is inclined upward from the bottom end of the handle portion 222, so that the thickness of the lower end of the handle portion 222 is greater than the thickness of the upper end of the handle portion 222, thereby increasing the contact area between the human hand and the handle portion 222. The first inclined surface 2221 extends from the bottom end of the handle portion 222 to the middle position in the height direction of the handle portion 222, so that the thickness of the upper end of the handle portion 222 can be kept unchanged, thereby avoiding an increase in the thickness of the door body 2. The lower end surface 2222 of the handle portion 222 is set as an arc surface. When a human hand contacts the handle portion 222, the fingers are generally in a bent state. The lower end surface 2222 of the handle portion 222 is set as an arc surface, which can improve its fit with the human hand, avoid hurting the hand, and improve the user experience.

[0079] like Figure 7 As shown, the bottom of the buckle groove 216 is set as an arc surface, which can match the curvature of the back of the human hand to further improve the user experience.

[0080] Fig.13 This is a schematic diagram of the connection structure between the handle structure and the upper end cover provided in this application. Fig.14 This is a schematic diagram of the structure of the upper cover provided in this application under the second visual sense. Fig.15 for Fig.14 Magnified view of area C.

[0081] like Figures 13 to 15 As shown, in some embodiments of the present application, connecting blocks 217 may be respectively provided at both ends of the upper end cover 215. The connecting block 217 extends into the buckle groove 216. The connecting block 217 is connected to the handle structure 22 through the first connecting member 23. In this way, the upper end cover 215 can be connected to the handle structure 22 from the inside, thereby improving the integrity of the door body 2. In this embodiment, the first connecting member 23 may be a screw. A first connecting hole 2172 is provided on the connecting block 217, and the axial direction of the first connecting hole 2172 is perpendicular to the connecting portion 221. A first through hole 2211 is provided on the connecting portion 221. By screwing through the first through hole 2211 and the first connecting hole 2172 in sequence, a stable connection between the handle structure 22 and the connecting block 217 can be achieved.

[0082] like Figure 7 As shown, a first avoidance surface 2171 may be provided on one side of the connection block 217 facing the first inclined surface 2221. The first avoidance surface 2171 is provided as an inclined surface corresponding to the first inclined surface 2221. The first avoidance surface 2171 is correspondingly connected to the first inclined surface 2221 to improve the compactness of the connection between the upper end cover 215 and the handle structure 22.

[0083] In some embodiments of the present application, a first gap 218 may be formed between the upper end cover 215 and the upper frame 211. The handle structure 22 includes an extension portion 223. The extension portion 223 is disposed on the side of the connecting portion 221 facing the upper end cover 215, and is inserted into the first gap 218. The connecting portion 221 of the handle structure 22 is located behind the extension portion 223 and forms a groove structure with the rear side of the upper end cover 215, and the upper frame 211 is inserted into the groove structure, so that the lower surface of the connecting portion 221 can limit the upper frame 211 in the height direction. In this way, the upper end cover 215, the upper frame 211 and the handle structure 22 can limit each other to form a stable structure.

[0084] In some embodiments of the present application, a second avoidance surface 2231 is formed on one side of the extension portion 223 facing the upper end cover 215. The second avoidance surface 2231 gradually approaches the upper end cover 215 from the free end of the extension portion 223 upward, that is, the front side of the free end of the extension portion 223 forms an inclined surface inclined downward. A third avoidance surface 2173 may be formed on one side of the upper portion of the connecting block 217 close to the extension portion 223. The third avoidance surface 2173 is arranged to be inclined downward from the top of the connecting block 217. In this way, the second avoidance surface 2231 and the third avoidance surface 2173 are arranged opposite to each other. When installing the door body 2, first connect the upper end cover 215, the left frame 213, the lower frame 212 and the right frame 214 together, then buckle the handle portion 222 of the handle structure 22 in front of the upper end cover 215, and then rotate the handle structure 22 downward to insert the extension portion 223 into the rear of the upper end cover 215 until the connecting portion 221 is connected to the top of the upper end cover 215. During the rotation process, the second avoidance surface 2231 and the third avoidance surface 2173 can cooperate with each other, which facilitates the installation of the handle structure 22.

[0085] like Figure 8 , Fig. 9 and Fig.13 As shown, in some embodiments of the present application, a second connection hole 2174 is provided on the connection block 217. The axial direction of the first connection hole 2172 is perpendicular to the extension portion 223. A second through hole 2232 is provided on the extension portion 223. The door body 2 may include a second connection member 24. The second connection member 24 passes through the second through hole 2232 and the second connection hole 2174 in sequence to achieve the connection between the back of the handle structure 22 and the back of the upper end cover 215, further improving the connection stability between the handle structure 22 and the upper end cover 215. The second connection member 24 can be a screw, which has a simple structure and high connection stability.

[0086] like Figure 7 , Fig.11 and Fig.15As shown, both ends of the handle portion 222 may be provided with a slot 2223. The slot 2223 is provided on the side of the handle portion 222 facing the connection block 217. The connection block 217 may be provided with a protrusion 2175, and the protrusion 2175 is correspondingly connected to the slot 2223. In this way, the handle portion 222 can be limited, and the connection stability between the handle structure 22 and the door frame 21 is further improved.

[0087] In summary, the present application sets the side of the handle portion 222 facing the door frame 21 as an inclined surface, so that the thickness of the lower end of the handle portion 222 is greater than the thickness of the upper end of the handle portion 222, thereby increasing the contact area between the handle portion 222 and the human hand without increasing the thickness of the door body 2; and by setting the lower end surface 2222 of the handle portion 222 as an arc surface, the fit between the handle portion 222 and the human hand is improved, which can prevent the handle portion 222 from hurting the hand and improve the comfort of use of the handle structure 22.

[0088] In addition, by setting a card slot 2223 at both ends of the handle portion 222 facing the upper end cover 215, a protrusion 2175 is set on the upper end cover 215, so that the protrusion 2175 is correspondingly connected with the card slot 2223, the connection stability between the handle structure 22 and the door frame 21 is improved, and the use experience of the door body 2 is further improved.

[0089] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and application concept of the present application, and all these changes or substitutions should fall within the protection scope of the claims attached to the present application.
