[0058] The following Figures 1 - 8 , through specific embodiments and their application scenarios, will provide a detailed description of the door body assembly and the refrigeration device provided by the embodiments of the utility model.

[0059] In the first aspect, as Figure 1 and Figure 6 shown, the embodiments of the present utility model provide a door body assembly applied to a refrigeration device, including: a box door 1, a cabinet door 2, a sliding module 4, and a hanging structure 5;

[0060] The cabinet door 1 is rotatably arranged on the cabinet body 3 of the refrigeration equipment through at least two hinges 9, and the cabinet door 2 is arranged on the side of the cabinet door 1 away from the cabinet body 3; the sliding module 4 includes a slide rail 41 and a sliding member 42; the slide rail 41 is arranged on the cabinet door 1 and extends along the width direction of the cabinet door 1; the sliding member 42 is movably arranged on the slide rail 41; the hanging structure 5 includes a hanging member 51 and a lap part 52, the hanging member 51 is arranged on the cabinet door 2, the lap part 52 is arranged on the sliding member 42, and the hanging member 51 is hung on the lap part 52;

[0061] Among them, the thickness of the cabinet door 1 is 18-60mm, for example, the thickness of the cabinet door 1 can be 18mm, 25mm, 35mm, 50mm, 55mm or 60mm; the thickness of the cabinet door 2 is 12-26mm, for example, the thickness of the cabinet door 2 can be 12mm, 15mm, 20mm or 26mm.

[0062] It is understandable that the door assembly is applied to refrigeration equipment such as refrigerators and freezers, and a hinge 9 is provided on the box body 3 of the refrigeration equipment, and the box door 1 is rotatably connected to the box body 3 through the hinge 9 to realize the opening or closing of the box door 1 relative to the box body 3. The outer side of the box door 1 is provided with a cabinet door 2, which can be a door panel, and the cabinet door 2 and the surrounding cabinets can be made of the same material to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinets, so that the refrigeration equipment is better coordinated with the surrounding environment.

[0063] For the sliding module 4, the slide rail 41 may be a C-shaped guide rail, the sliding member 42 may be a sliding block, and at least a portion of the sliding member 42 may be movably disposed in a slide groove of the C-shaped guide rail along an extension direction of the C-shaped guide rail.

[0064] For the hanging structure 5, the hanging part 51 is detachably installed on the cabinet door 2 by means of locking parts such as bolts and rivets. The overlapping part 52 can be a hanging groove or a bayonet provided on the sliding part 42. The hanging part 51 is quickly and reliably hung on the overlapping part 52 under the action of gravity of the cabinet door 2.

[0065] As can be seen from the above, by setting a sliding module 4 and a hanging structure 5 between the box door 1 and the cabinet door 2, the sliding module 4 includes a sliding rail 41 and a sliding member 42 that are slidably arranged, and the sliding rail 41 of the sliding module 4 can be connected to the box door 1 to achieve the installation of the sliding module 4. After the hanging member 51 of the hanging structure 5 is installed on the cabinet door 2, the hanging member 51 is directly hung on the overlapping portion 52 on the sliding member 42, so that the cabinet door 2 can be easily installed, and the cabinet door can slide left and right relative to the box door along the width direction. This cabinet door installation method is easy to operate, reduces the labor intensity of the installer, and improves the cabinet door installation efficiency.

[0066] Further, in practical applications, when the refrigeration device is installed in an embedded manner relative to the cabinet, during the process of opening or closing the door 1 of the refrigerator, the cabinet door 2 can move relative to the door 1 in the width direction, avoiding the cabinet door 2 from touching the surrounding cabinets during the opening and closing of the door 1, and preferably meeting the normal opening and closing requirements of the door 1 of the refrigeration device.

[0067] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 shown, the hanging member 51 includes a fixed seat 511 and a hook 512. The fixed seat 511 is provided on the cabinet door 2 and is connected to the hook 512; the overlapping portion 52 includes a hanging interface, and the hook 512 is hung on the hanging interface.

[0068] It can be understood that one end of the hook 512 is in a hook shape and is hung in the hanging interface, and the other end of the hook 512 is connected to the fixed seat 511; the fixed seat 511 is detachably connected to the cabinet door 2 through a locking member. Among them, the hanging member 51 can be an integral metal member composed of the fixed seat 511 and the hook 512.

[0069] In order to reduce the installation gap between the door 1 and the cabinet door 2, the hanging interface is provided on the side surface of the sliding member 42 facing the cabinet door 2, and the fixed seat 511 is installed on the side surface of the cabinet door 2 facing the door 1.

[0070] In some embodiments, such as Figure 4 shown, in order to ensure that the hanging member 51 can be adjustably installed on the cabinet door 2, the fixed seat 511 is provided with a plurality of mounting holes, and the fixed seat 511 is connected to the cabinet door 2 through a locking member passing through the mounting holes; among them, at least part of the mounting holes extend in a first direction, and the first direction is perpendicular or inclined to the width direction.

[0071] It can be understood that the first direction is parallel to the surface of the cabinet door 2, which enables the hanging member 51 to adjust the installation position on the surface of the cabinet door 2. In practical applications, the hanging member 51 can be initially fixed on the cabinet door 2 through a locking member passing through one of the plurality of mounting holes, and then the hanging member 51 is hung on the overlapping portion 52, and the installation position of the hanging member 51 is adjusted. After the installation position of the hanging member 51 is adjusted, the hanging member 51 is fixed through a locking member passing through other mounting holes.

[0072] Among them, when the first direction is perpendicular to the width direction, the position of the cabinet door 2 relative to the door 1 can be adjusted in the height direction by adjusting the installation position of the hanging member 51; when the first direction is inclined to the width direction, the position of the cabinet door 2 relative to the door 1 can be adjusted in the height direction and the width direction respectively by adjusting the installation position of the hanging member 51.

[0073] In some embodiments, such asFigure 4 As shown, the mounting holes include a first round hole 5101, a strip hole 5102, and a second round hole 5103; the first round hole 5101, the strip hole 5102, and the second round hole 5103 are arranged in the width direction, and the strip hole 5102 extends along the first direction.

[0074] It can be understood that when installing the hanging part 51, first, the hanging part 51 is preliminarily fixed on the cabinet door 2 through a locking part passing through the strip hole 5102, then the hanging part 51 is hung on the overlapping part 52, and the installation position of the hanging part 51 is adjusted. After the installation position of the hanging part 51 is adjusted, the hanging part 51 is fixed through the locking part passing through the first round hole 5101 and the second round hole 5103.

[0075] In some embodiments, as Figure 4 shown, the hanging part 51 further includes a reinforcing rib 513, and the reinforcing rib 513 is arranged between the fixed seat 511 and the hook 512.

[0076] It can be understood that by arranging the reinforcing rib 513 between the fixed seat 511 and the hook 512, the bonding strength between the fixed seat 511 and the hook 512 can be ensured, and the connection structure failure between the fixed seat 511 and the hook 512 due to excessive force can be prevented.

[0077] Among them, multiple reinforcing ribs 513 can be arranged, and the multiple reinforcing ribs 513 are arranged side by side.

[0078] In some embodiments, in order to ensure the structural strength of the hanging part 51, the thickness of the hanging part 51 can also be set to be greater than or equal to 2 mm. For example, the thickness of the hanging part 51 is 2 mm, 2.5 mm, 3 mm, or 3.5 mm.

[0079] In some embodiments, as Figure 3 and Figure 5 shown, the hanging interface includes a first opening area 521 and a second opening area 522; the first opening area 521 and the second opening area 522 are communicated, the first opening area 521 is arranged above the second opening area 522 along the height direction of the cabinet door 1; the opening width of the first opening area 521 is greater than the opening width of the second opening area 522, and the opening width of the second opening area 522 is adapted to the width of the hook 512, and the hook 512 is hung on the lower edge of the second opening area 522.

[0080] It can be understood that when hanging the hanging part 51 into the hanging interface, first, the hook 512 of the hanging part 51 is inserted into the first opening area 521, and then the hook 512 is controlled to move from the first opening area 521 to the second opening area 522 until the hook 512 is hung on the lower edge of the second opening area 522 under the gravity of the cabinet door 2.

[0081] Since the opening width of the first opening area 521 is greater than the width of the hook 512, the hook 512 of the hanging member 51 can be conveniently inserted into the first opening area 521. Since the opening width of the second opening area 522 is adapted to the width of the hook 512, when the hook 512 is hung on the lower edge of the second opening area 522, the side of the hook 512 will abut against the side wall of the second opening area 522 along the width direction of the door 1, and the hook 512 will be limited in the second opening area 522 in a vertically distributed hanging posture, ensuring the stability of the hanging posture of the hanging member 51.

[0082] In some embodiments, as Figure 3 shown, the sliding member 42 includes a ball bracket 421 and an adapter seat 422. The ball bracket 421 is movably arranged on the slide rail 41 along the width direction. The adapter seat 422 is connected to the ball bracket 421, and the hanging member 51 is hung on the adapter seat 422.

[0083] It can be understood that the slide rail 41 can be a C-shaped guide rail, and the ball bracket 421 and the slide rail 41 can be in rolling fit by using balls, so that the sliding member 42 can move smoothly relative to the slide rail 41 and there will be no abnormal noise during the movement.

[0084] At the same time, the adapter seat 422 and the ball bracket 421 can be connected by welding, and the hanging interface shown in the above embodiment can be constructed on the adapter seat 422 so that the hook 512 of the hanging member 51 can be hung in the hanging interface.

[0085] Furthermore, along the extending direction of the slide rail 41, the extending length of the ball bracket 421 can be set to be greater than the extending direction of the adapter seat 422. This design can increase the contact area between the ball bracket 421 and the slide rail 41 and reduce the contact friction between the ball bracket 421 and the slide rail 41, thereby ensuring the stability and reliability of the movement of the sliding member 42 relative to the slide rail 41.

[0086] In some embodiments, as Figure 7 and Figure 8 shown, the door assembly further includes: a sliding door mechanism 6. The sliding door mechanism 6 is arranged on the cabinet body 3 or the door 1. The sliding door mechanism 6 is in transmission connection with the cabinet door 2 and is used to drive the cabinet door 2 to move relative to the door 1 along the width direction during the opening and closing process of the door 1. The refrigeration device is configured to be arranged in the accommodation space between the first cabinet body 7 and the second cabinet body 8. During the opening or closing process of the door 1, the sliding door mechanism 6 changes the position of the cabinet door 2 on the door 1 so that the cabinet door 2 avoids the first cabinet body 7 or the second cabinet body 8.

[0087] It is understandable that an opening is provided on the outer side of the accommodating space between the first cabinet body 7 and the second cabinet body 8. This design enables the box body 3 of the refrigeration device to be integrally embedded into the accommodating space. During the process of the box door 1 passing through the opening to control the opening or closing of the accommodating space, the sliding door mechanism 6 is configured to drive the cabinet door 2 to move in the width direction away from or towards the hinge 9. This design can ensure that the side of the cabinet door 2 avoids the side walls of the first cabinet body 7 and the second cabinet body 8, preventing interference between the cabinet door 2 and the side walls of the first cabinet body 7 and the second cabinet body 8, and enabling the box door 1 to be opened and closed smoothly.

[0088] During the process of opening the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction towards the side away from the hinge 9. In this way, the cabinet door 2 can smoothly avoid the side wall of the second cabinet body 8, enabling the box door 1 to be fully opened, which is convenient for users to store and retrieve items.

[0089] Similarly, during the process of closing the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction towards the side close to the hinge 9. When the box door 1 is fully closed, the cabinet door 2 will return to its initial position. In this way, the cabinet door 2 can smoothly avoid the side wall of the first cabinet body 7, enabling the box door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0090] In this embodiment, the cabinet door 2 is movably arranged on the outer side of the box door 1 in the width direction of the box door 1, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the box door 1 during the opening or closing of the box door 1, so that the box door 1 can avoid the first cabinet body 7 and the second cabinet body 8 on the side during the opening and closing processes, preventing interference between the cabinet door 2 and the outside when the box door 1 rotates, and meeting the usage requirements of users in different scenarios. This design not only improves the convenience of use but also can avoid possible damage to the door body assembly during use. At the same time, this design also enables the refrigeration device to better integrate into the home environment, achieving the effects of overall aesthetics and sealing.

[0091] In some embodiments, as Figure 8 shown, the sliding door mechanism 6 is connected to the sliding member 42 to drive the sliding member 42 to move along the slide rail 41.

[0092] It is understandable that during the opening and closing of the box door 1, the sliding door mechanism 6 drives the sliding member 42 to move relative to the slide rail 41 in the width direction. Since the sliding member 42 is connected to the cabinet door 2 through the hanging structure 5, the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the box door 1, ensuring that the cabinet door 2 does not interfere with the side cabinet body. This design realizes the integration of the sliding door mechanism 6 and the sliding module 4.

[0093] Among them, since there are multiple sliding modules 4, at least one of the multiple sliding modules 4 close to the hinge 9 can be integrally designed with the sliding door mechanism 6.

[0094] In some embodiments, as Figure 7 and Figure 8 shown, the box door 1 is rotatably connected to the box body 3 through the hinge 9, and the cabinet door 2 can move between a first position and a second position along the width direction relative to the box door 1; when the cabinet door 2 is in the first position, the box door 1 closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 approaches the hinge 9; when the cabinet door 2 is in the second position, the box door 1 opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 moves away from the hinge 9, and the side of the cabinet door 2 and the side of the box door 1 are misaligned to avoid the side wall of the first cabinet 7 or the second cabinet 8.

[0095] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the box door 1 closes the storage compartment, the box door 1 is in a closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 9 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the box door 1 are flush. At this time, the cabinet door 2 can completely block the box door 1 to ensure that the cabinet door 2 of the refrigeration device exposed in the accommodation space is consistent with the surrounding first cabinet 7 and second cabinet 8 in appearance.

[0096] When the box door 1 opens the storage compartment, the box door 1 is in an open state, and the side of the cabinet door 2 is at a second distance (the second distance is greater than the first distance) relative to the hinge 9 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the box door 1 are misaligned and form a gap that can accommodate the side wall of the first cabinet 7 or the second cabinet 8, so as to avoid collision or interference between the cabinet door 2 and the first cabinet 7 or the second cabinet 8 caused by the opening of the box door 1.

[0097] In some embodiments, as Figure 8 shown, the sliding door mechanism 6 includes: a trigger and a linear drive. The trigger is used to obtain the opening and closing signal of the box door 1; the linear drive is arranged between the box door 1 and the cabinet door 2 and is connected to the trigger; wherein, the linear drive is used to drive the cabinet door 2 to move along the width direction of the box door 1 according to the opening and closing signal fed back by the trigger.

[0098] It can be understood that in order to facilitate controlling the working state of the linear drive according to the opening and closing signal fed back by the trigger, the trigger can be electrically connected to the control module, and the control module and the linear drive are electrically connected.

[0099] The trigger can be a photoelectric switch, which judges the opening and closing state of the box door 1 by detecting the distance change of the box door 1 relative to the box body 3. The trigger can also be an angle sensor, which judges the opening and closing state of the box door 1 by detecting the angle change of the box door 1 relative to the box body 3;

[0100] The linear driving member can be a telescopic rod such as a cylinder or an electric push rod. The linear driving member extends in the width direction. The first end of the linear driving member is connected to the cabinet door 1, and the second end of the linear driving member is connected to the cabinet door 2, so as to drive the cabinet door 2 to move relative to the cabinet door 1 in the width direction.

[0101] Wherein, in the case that the door body assembly includes the above-mentioned sliding module 4 and the hanging structure 5, the linear driving member is arranged on the cabinet door 1. The first end of the linear driving member is connected to the cabinet door 1, and the second end of the linear driving member is connected to the sliding member 42 of the sliding module 4.

[0102] Taking the trigger member as an angle sensor as an example below, the control of the cabinet door 2 by the linear driving member during the opening and closing of the cabinet door 1 will be specifically described as follows.

[0103] In practical applications, the angle sensor is installed on the hinge axis corresponding to the hinge 9 to monitor the rotation state of the cabinet door 1 relative to the hinge axis. When the cabinet door 1 is opened, the angle sensor feeds back an opening signal to the linear driving member, and the linear driving member drives the cabinet door 2 to move in the width direction of the cabinet door 1 away from the hinge 9; when the cabinet door 1 is closed, the angle sensor feeds back a closing signal to the linear driving member, and the linear driving member drives the cabinet door 2 to move in the width direction of the cabinet door 1 towards the hinge 9.

[0104] Furthermore, as the opening or closing amplitude of the cabinet door 1 is different, the angle sensor can also obtain the rotation angle of the cabinet door 1. The linear driving member can determine the preset value of the movement according to the rotation angle. During the opening process of the cabinet door 1, according to the rotation angle when the cabinet door 1 is opened, the stroke of the telescopic end of the linear driving member is determined, and then the linear driving member drives the cabinet door 2 to move a preset distance away from the hinge 9 to avoid interference between the cabinet door 2 and the external cabinet body; correspondingly, during the closing process of the cabinet door 1, according to the rotation angle when the cabinet door 1 is closed, the stroke of the telescopic end of the linear driving member is determined, and then the linear driving member drives the cabinet door 2 to move a preset distance towards the hinge 9 to avoid interference between the cabinet door 2 and the external cabinet body, and finally the reset of the cabinet door 2 is realized.

[0105] In some embodiments, as Figure 1 shown, in order to ensure the stability and reliability of the movement of the cabinet door 2 relative to the cabinet door 1, multiple sets of the sliding module 4 and the hanging structure 5 are respectively provided and arranged in a one-to-one correspondence. At least one set of the sliding module 4 is arranged between the upper ends of the cabinet door 1 and the cabinet door 2, and at least one set of the sliding module 4 is arranged between the lower ends of the cabinet door 1 and the cabinet door 2.

[0106] Specifically, there are four sets of sliding modules 4, two of which are arranged along the width direction of the door 1 and are arranged between the upper end of the door 1 and the upper end of the cabinet door 2, and the other two sets of sliding modules 4 are arranged along the width direction of the door 1 and are arranged between the lower end of the door 1 and the lower end of the cabinet door 2.

[0107] In some embodiments, as Figure 1 and Figure 6 shown, the door 1 is provided with a groove 101, and the sliding module 4 is arranged in the groove 101; the door body assembly further includes a decorative member for covering the notch end of the groove 101.

[0108] It can be understood that when the cabinet door 2 is installed on the outer side of the door 1, the sliding module 4 on the door 1 is connected to the cabinet door 2 through the hanging structure 5, and there is no decorative member at the notch end of the groove 101 at this time.

[0109] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the door 1, the sliding module 4 is no longer used at this time. By covering the notch end of the groove 101 with the decorative member, a hidden design of the sliding module 4 can be achieved, ensuring the aesthetic appearance of the door 1.

[0110] In a second aspect, as Figure 6 、 Figure 7 and Figure 8 shown, an embodiment of the present invention further provides a refrigeration device, including: a box body 3 and the door body assembly as described in any one of the above, the box body 3 has a storage compartment, and the door 1 is rotatably arranged on the box body 3 to open or close the storage compartment.

[0111] It can be understood that the box body 3 can be provided with multiple storage compartments, and the multiple storage compartments are arranged in sequence from top to bottom along the height direction of the box body 3. The box body 3 is configured with a set of door body assemblies for controlling its opening and closing state for each storage compartment. Among them, the box body 3 is provided with hinges 9 on one side corresponding to each storage compartment, and the box body 3 can be rotatably connected to the door 1 of the door body assembly corresponding to the storage compartment through the hinges 9.

[0112] For each set of door body assemblies, since the cabinet door 2 can move left and right relative to the door 1 along the width direction, when the refrigeration device is fully embedded, during the process of opening the door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the door 1 to avoid the cabinets around the refrigeration device; during the process of closing the door 1, the cabinet door 2 is controlled to move towards the side close to the hinge 9 relative to the door 1 until the cabinet door 2 returns to its original position, ensuring that the side edges of the door 1 and the cabinet door 2 are flush.

[0113] Since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiments, the refrigeration device shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
