[0033] See also Figures 1 to 6 , Figure 1 It is a front structural schematic diagram of an embodiment of a door assembly of the present application; Figure 2 It is a schematic diagram of the exploded structure of an embodiment of a door assembly of the present application; Figure 3 It is a schematic cross-sectional structure diagram of an embodiment of a door assembly of the present application; Figure 4 It is another cross-sectional structural schematic diagram of an embodiment of a door assembly of the present application; Figure 5 is a schematic diagram of the three-dimensional structure of the handle assembly of the present application in an initial position; Figure 6 It is a schematic diagram of the three-dimensional structure of the handle assembly of the present application at the end position.

[0034] An embodiment of the present application provides a door body assembly 10. The door body assembly 10 has an outer main plane 112. The door body 11 is also formed with a recessed portion 111. The handle assembly 12 is disposed in the recessed portion 111, and the handle assembly 12 includes a handle 121 and a rotating mechanism 122. The handle 121 includes a first panel 1211. The rotating mechanism 122 is connected between the first panel 1211 and the door body 11. The handle assembly 12 has an initial position A and an end position B. In the initial position A, the first panel 1211 is flush with the outer main plane 112 to cover the recessed portion 111. When the first panel 1211 is subjected to an external force, the rotating mechanism 122 rotates to drive the first panel 1211 to move from the initial position A to the end position B, so that the recessed portion 111 is exposed.

[0035] It can be seen from the above structure that one end of the door body 11 in the present application is recessed to form a recessed portion 111, and the handle assembly 12 is arranged in the recessed portion 111. At this time, the handle assembly 12 can be hidden to avoid the handle assembly 12 being exposed outside the door body 11, which affects the appearance and wastes a certain amount of space.

[0036] By setting the rotating mechanism 122, the friction between the handle 121 and the door body 11 can be reduced, and the user can save more effort in the process of opening or closing the door body 11. In addition, in the process of opening or closing the door body 11, the user can apply a certain external force to the first panel 1211, so that the rotating mechanism 122 can rotate, and the rotation of the rotating mechanism 122 can drive the first panel 1211 to move toward the initial position A or the terminal position B. At this time, there is no need to set a motor or other electric mechanism to provide power to the rotating mechanism 122 to drive the rotating mechanism 122 to rotate. At this time, the number of structural parts can be well reduced, thereby reducing the production cost of the door body assembly 10. In addition, in the process of opening or closing the door body 11 by the user, if the rotating mechanism 122 is driven to rotate by a motor, there may be insufficient power or power failure of the motor, which may cause the door body 11 to be unable to be opened or closed normally. Therefore, by applying an external force to the first panel 1211, the opening or closing of the door body 11 can be free from environmental restrictions, thereby making it more convenient for users to use.

[0037] Furthermore, when the handle assembly 12 is located at the initial position A, the first panel 1211 is flush with the outer main plane 112 to cover the recessed portion 111. At this time, the outer main plane 112 of the door body 11 can be made smoother, and the aesthetics of the door body 11 can also be higher.

[0038] Preferably, when the handle assembly 12 is located at the initial position A, the first panel 1211 is flush with the outer main plane 112, and at this time, the first panel 1211 and the outer main plane 112 are in the same plane. Of course, the first panel 1211 and the outer main plane 112 can also be in parallel planes within a certain error range, that is, the two can be non-coplanar within a certain error range, wherein the error can be 0-5mm, which is not limited here.

[0039] It should be noted that, since the door body 11 usually has an inner main plane (not shown in the figure) and an outer main plane 112, and the inner main plane and the outer main plane 112 of the door body 11 are formed through a foaming process or other production processes to make the door body 11 have a certain thickness, the depression of the door body 11 is equivalent to the outer main plane 112 of the door body 11 being depressed toward the inner main plane of the door body 11, thereby forming a depressed portion 111.

[0040] Optionally, the recessed portion 111 can be formed at the end of the door body 11, or the recessed portion 111 can be formed at the bottom of the door body 11, or the recessed portion 111 can be formed at the side wall of the door body 11, which can be specifically set according to the usage scenario of the door body assembly 10 and is not limited here.

[0041] In one embodiment of the present application, the door body 11 also has an outer peripheral wall 113. The recessed portion 111 is formed at the junction of the outer main plane 112 and the outer peripheral wall 113. The handle 121 includes a second panel 1212 intersecting with the first panel 1211. In the initial position A, the second panel 1212 is flush with the outer peripheral wall 113 to cover the recessed portion 111. When the recessed portion 111 is formed at the bottom of the door body 11, it can not only make the outer main plane 112 of the door body 11 more flat and simple, but also can well improve the flatness of the outer peripheral wall 113 of the door body 11. Specifically, when looking up from the bottom of the door body 11, there can be no gap at the bottom to improve the flatness of the lower surface of the door body 11, thereby improving the aesthetic appearance of the door body 11.

[0042] Optionally, when the recessed portion 111 is formed at the top of the door body 11, when looking down from the top of the door body 11, there is no gap at the top, which can improve the flatness of the upper surface of the door body 11. When the recessed portion 111 is formed on the side wall of the door body 11, the flatness of the side wall of the door body 11 can be improved. This is not limited here.

[0043] In one embodiment of the present application, the recessed portion 111 has a first inner wall surface 1111 arranged opposite to the outer main plane 112. The rotating mechanism 122 includes a rotating member 123 and a reset member 13. Among them, one end of the rotating member 123 is rotatably arranged in the recessed portion 111 and close to the first inner wall surface 1111, and the other end is rotatably connected to the handle 121. One end of the reset member 13 abuts against the first inner wall surface 1111, and the other end abuts against the rotating member 123 to drive the rotating member 123 to rotate to the initial position A. Specifically, when the first panel 1211 is subjected to an external force, at this time, since the rotating member 123 is connected to the handle 121, the rotating member 123 will also rotate due to the force. When the rotating member 123 rotates, it will drive the handle 121 to rotate together, so that the handle 121 can move from the initial position A to the terminal position B. The setting of the rotating member 123 can make the movement process of the entire handle 121 more labor-saving. The setting of the reset member 13 can automatically drive the handle 121 to move from the end position B toward the initial position A, and the user does not need to apply force to the first panel 1211 again to make the first panel 1211 return to the end position B. Therefore, the reset member 13 can autonomously drive the handle 121 to reset, so that the process of resetting the handle 121 can be more labor-saving. At the same time, the reset member 13 also has the advantage of a simple structure.

[0044] Specifically, the rotating member 123 includes a first rotating shaft 1221, a connecting portion 1222 and a second rotating shaft 1223. The first rotating shaft 1221 is rotatably disposed in the recessed portion 111 and is close to the first inner wall surface 1111. The connecting portion 1222 is connected to the first rotating shaft 1221. One end of the second rotating shaft 1223 is connected to the connecting portion 1222, and the other end is rotatably connected to the first panel 1211. When the handle assembly 12 moves from the initial position A to the terminal position B, the first panel 1211 is subjected to an external force, and the first panel 1211 moves toward the direction of the first inner wall surface 1111. At this time, the movement of the first panel 1211 drives the second rotating shaft 1223 to move, and the second rotating shaft 1223 drives the connecting portion 1222 and the first rotating shaft 1221 to move. By providing the first rotating shaft 1221 , the connecting portion 1222 and the second rotating shaft 1223 , the rotation process of the entire rotating member 123 can be made more stable. The provision of the first rotating shaft 1221 and the second rotating shaft 1223 can also save the user effort when opening or closing the door body 11 .

[0045] Also, see Figures 1 to 7 , Figure 7 It is a three-dimensional structural schematic diagram of a torsion spring of an embodiment of a door body assembly of the present application. The reset member is a torsion spring 131. The torsion spring 131 includes a main body 1311, a first extension 1312 and a second extension 1313. Among them, the main body 1311 is sleeved on the first rotating shaft 1221, and the first extension 1312 and the second extension 1313 are in contact with the first inner wall surface 1111. Since the torsion spring 131 itself has a high load-bearing capacity and rebound performance, the structure can withstand a large rotation angle and can quickly restore the deformation after deformation. At the same time, the torsion spring 131 has a long durability and lifespan. Therefore, by setting the torsion spring 131, the service life of the handle assembly 12 can also be well improved. And by the first extension 1312 and the second extension 1313 abutting against the first inner wall surface 1111, the structure of the torsion spring 131 can also be made more stable during the rotation of the handle.

[0046] Further, the second rotating shaft 1223 includes two rotating posts 1224 arranged at intervals. The first panel 1211 is provided with two rotating grooves 1213 corresponding to the two rotating posts 1224. The two rotating posts 1224 are respectively inserted into the two rotating grooves 1213. Specifically, during the installation of the rotating member 123, the two rotating posts 1224 are respectively inserted into the two rotating grooves 1213, at which time, a preliminary positioning and preliminary effect can be played on the installation of the rotating member 123. On the one hand, it can prevent the rotating member 123 from being displaced during the installation process, thereby causing the rotating member 123 to fall off or the rotating member 123 to be unable to rotate. On the other hand, it can also prevent the rotating member 123 from being separated from the first panel 1211 during the later use, thereby affecting the stability of the rotating member 123 during use. Therefore, the two rotating posts 1224 are both inserted into the rotating grooves 1213, which can also well improve the strength of its positioning and limiting, and better improve the stability of the rotating member 123 during the installation process and the later use process.

[0047] It should be noted that the distance between the two rotating grooves 1213 is greater than the height of the rotating column 1224 that is away from the second panel 1212 in the extension direction of the door body 11. At this time, in the process of inserting the rotating column 1224 into the rotating groove 1213, the rotating column 1224 that is away from the second panel 1212 can be smoothly inserted into the rotating groove 1213 corresponding to it, thereby achieving smooth installation.

[0048] Preferably, in some embodiments, a plurality of first grooves 17 are provided on both surfaces of the connection portion 1222 , and reinforcing ribs 18 are formed between adjacent first grooves 17 , so that the structural strength of the connection portion 1222 can be better improved.

[0049] A clearance block 19 is formed at one end of the connecting portion 1222 facing the second rotating shaft 1223. The size of the first groove 17 near the clearance block 19 is larger than the size of the first groove 17 at other positions. At this time, the clearance block 19 can have a certain elasticity, and can play a certain clearance role for the rotating column 1224 away from the second panel 1212 during the process of the rotating column 1224 being inserted into the rotating groove 1213, so as to avoid the failure of the installation of the rotating column 1224. Therefore, the clearance block 19 can improve the success rate of the rotating column 1224 being installed in the rotating groove 1213.

[0050] See also Figures 1 to 8 , Figure 81 is a schematic diagram of the three-dimensional structure of a handle of an embodiment of a door assembly of the present application. In order to limit the moving position of the rotating member 123, in an embodiment of the present application, one end of the recessed portion 111 has a second inner wall surface 1112 arranged opposite to the first inner wall surface 1111. The handle 121 also includes a limiting panel 1225 connected to the first panel 1211. When the handle assembly 12 is located at the initial position A, the limiting panel 1225 abuts against the second inner wall surface 1112. Specifically, in the process of the handle assembly 12 rotating from the initial position A to the final position B, the movement trajectory of the rotating member 123 forms a fan shape. At this time, corresponding to the movement trajectory, a second inner wall surface 1112 is formed in the recessed portion 111. Therefore, when the handle assembly 12 returns to the initial position A from the final position B, the rotating member 123 moves autonomously under the action of the reset member 13 so that the handle 121 moves along the second inner wall surface 1112 to the initial position A, and when the limiting panel 1225 abuts against the second inner wall surface 1112, the first panel 1211 stops moving. Therefore, in the process of the handle assembly 12 rotating from the final position B to the initial position A, the second inner wall surface 1112 and the limiting panel 1225 cooperate to effectively prevent the rotating member 123 from excessive movement in the process of rotating to the initial position A, thereby causing the first panel 1211 to protrude from the outer main plane 112 of the door body 11, affecting the flatness and simplicity of the outer main plane 112 of the door body 11. Therefore, the setting of the limiting panel 1225 can play a good limiting role on the rotating mechanism 122, thereby improving the flatness and simplicity of the outer main plane 112 of the door body 11.

[0051] Preferably, the second inner wall surface 1112 is an arc surface corresponding to the motion trajectory of the rotating member 123. Of course, in some other embodiments, the second inner wall surface 1112 may also be a plane, which is not limited here.

[0052] Furthermore, the recessed portion 111 further includes a hand grip groove 1314. The hand grip groove 1314 extends toward an end away from the second panel 1212. When the user opens and closes the door body 11, the user can place the hand in the hand grip groove 1314. Therefore, the setting of this structure is more ergonomic, so that the user can save more effort in opening and closing the door body 11.

[0053] See also Figures 1 to 10 , Fig. 9 is a schematic structural diagram of the handle assembly of the present application when it is located at an initial position; Fig.10It is a schematic diagram of the structure when the handle assembly of the present application is located at the terminal position. In one embodiment of the present application, a plurality of stop blocks 1214 are arranged at intervals on the side of the first panel 1211 away from the second panel 1212. When the handle assembly 12 is in the initial position A, the stop block 1214 abuts against the inner side wall of the hand-grip groove 1314. Specifically, when the stop block 1214 abuts against the inner side wall of the hand-grip groove 1314, the handle assembly 12 stops moving. Therefore, the structure of the stop block 1214 can effectively prevent the handle assembly 12 from moving excessively and causing the first panel 1211 to protrude from the surface of the door body 11. Therefore, this structure can play a good role in limiting the position of the handle assembly 12, thereby improving the flatness and neatness of the outer main plane 112 of the door body 11.

[0054] In some embodiments, a second groove 171 is further formed in the recessed portion 111, and the second groove 171 is arranged close to the second inner wall surface 1112 and parallel to the buckle groove 1314. The connecting portion 1222 forms a limiting rib 181 at one end away from the second panel 1212. When the handle assembly 12 is in the initial position A, the limiting rib 181 abuts against the inner wall surface of the second groove 171. At this time, the limiting rib 181 can also play a certain limiting role in the rotation of the rotating member 123, so as to avoid the rotating member 123 from moving excessively and causing the first panel 1211 to protrude from the surface of the door body 11, thereby improving the flatness and neatness of the outer main plane 112 of the door body 11.

[0055] Preferably, in some embodiments, two rotating mechanisms 122 are usually provided. In this case, during the installation of the rotating member 123, the limiting rib 181 abuts against the inner wall of the second groove 171, which can also play a good positioning role in the installation of the rotating member 123, so that the two rotating mechanisms 122 can be located on the same straight line, so as to facilitate the installation of the handle 121.

[0056] Of course, the number of the rotating mechanisms 122 may be greater, and there is no limitation here.

[0057] See also Figures 1 to 11 , Fig.111 is a schematic diagram of the three-dimensional structure of the pressure cover of an embodiment of the door body assembly of the present application. In an embodiment of the present application, the handle assembly 12 also includes a pressure cover 14 and a fastener 15. Among them, the pressure cover 14 is covered on the outer peripheral wall 113 of the door body 11 and is arranged corresponding to the first rotating shaft 1221. The pressure cover 14 is provided with a first through groove 141 for the first rotating shaft 1221 to pass through at the first rotating shaft 1221. The pressure cover 14 is also provided with a second through groove 142, and the fastener 15 passes through the second through groove 142 to connect with the door body 11. Specifically, in the process of installing the rotating member 123, the first rotating shaft 1221 is passed through the first through groove 141, and is connected to the door body 11 through the second through groove 142 by the fastener 15. At this time, it can play a good fixing role on the rotating member 123, so that the entire rotating member 123 can ensure the stability of the structure during the rotation process. Furthermore, the fastener 15 also has the advantages of simple and quick installation operation.

[0058] Optionally, the first through slot 141 may also be a half slot, in which case one end of the first rotating shaft 1221 is disposed in the half slot, and then the fastener 15 passes through the second through slot 142 and is connected to the door body 11 to fix the rotating member 123, and in this case the stability of the rotating member 123 during rotation can also be achieved. This is not limited here.

[0059] In one embodiment of the present application, the door body assembly 10 also includes a cover plate 16. The cover plate 16 is provided on one side of the door body 11 where the recessed portion 111 is provided. An opening is formed on the cover plate 16 corresponding to the recessed portion 111. The cover plate 16 includes a first cover plate 161 and a second cover plate 162. The first cover plate 161 is provided on the outer main plane 112 of the door body 11. The second cover plate 162 is provided on the outer peripheral wall 113 of the door body 11. The provision of the first cover plate 161 can well shield some other structural members on the outer main plane 112 of the door body 11, so as to improve the aesthetics of the outer main plane 112 of the door body 11. The provision of the second cover plate 162 can well shield some other structures on the outer peripheral wall 113. Therefore, the structure of the cover plate 16 can well improve the overall aesthetics of the door body 11.

[0060] It should be noted that there is a certain gap between the second cover plate 162 and the second panel 1212 . When the handle assembly 12 moves to the end position B, the second panel 1212 extends toward the inside of the door body 11 .

[0061] See also Figures 1 to 12 , Fig.12It is a front structural diagram of an embodiment of a refrigeration device of the present application. Another embodiment of the present application provides a refrigeration device 20, and the refrigeration device 20 includes any of the above-mentioned door body assemblies 10. By providing a rotating mechanism 122, the magnitude of the friction between the handle 121 and the door body 11 can be reduced, and the user can save more effort in the process of opening or closing the door body 11. In addition, in the process of opening or closing the door body 11, the user can apply a certain external force to the first panel 1211, thereby enabling the rotating mechanism 122 to rotate, and the rotation of the rotating mechanism 122 can drive the first panel 1211 to move toward the initial position A or the end position B. At this time, there is no need to provide a motor or other electric mechanism to provide power to the rotating mechanism 122 to drive the rotating mechanism 122 to rotate. At this time, the number of structural parts can be well reduced, thereby reducing the production cost of the door body assembly 10. Furthermore, when the user opens or closes the door body 11, if a motor is used to drive the rotating mechanism 122 to rotate, the motor may not be able to open or close normally due to insufficient power or power outage. Therefore, by applying an external force to the first panel 1211, the opening or closing of the door body 11 is not restricted by the environment, which makes it more convenient for users to use. Furthermore, when the handle assembly 12 is located at the initial position A, the first panel 1211 is flush with the outer main plane 112 to cover the recessed portion 111. At this time, the outer main plane 112 of the door body 11 can be made smoother, and the aesthetics of the door body 11 can also be higher. Optionally, the refrigeration device 20 can be a refrigerator, a freezer, etc., which is not limited here.

[0062] Of course, in some other embodiments, the door body 11 can also be applied to structures such as cabinets, which can also improve the overall aesthetics of the cabinet.

[0063] It should be noted that the terms "horizontal", "vertical" and the like do not mean that the components are absolutely horizontal or vertical, but can be slightly tilted; the terms "parallel", "vertical" and the like do not mean that the components are absolutely parallel or vertical, but can form a certain angle deviation. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. In addition, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the present application is usually placed when used, which is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.
