In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0052] Combine the following Figures 1 - 7 , the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0053] In the first aspect, Figure 1 , Figure 4 and Figure 5 As shown, the embodiment of the utility model provides a door assembly, which is applied to refrigeration equipment, including: a box door 1, a cabinet door 2, a sliding module 4 and a hanging structure 5;

[0054] 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 slide 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 slide member 42 is movably arranged on the slide rail 41; the hanging structure 5 includes a clamping joint 51 and an elastic clamping seat 52, the clamping joint 51 and the elastic clamping seat 52 are respectively arranged on the slide member 42 and the cabinet door 2, the elastic clamping seat 52 has a clamping cavity 5201 and a limiting opening connected to the clamping cavity 5201, the clamping joint 51 can be clamped in the clamping cavity 5201 by squeezing the limiting opening; the limiting opening is used to limit the clamping joint 51 in the clamping cavity 5201;

[0055] 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.

[0056] It is understandable that the door body assembly is applied to refrigeration equipment such as refrigerators and freezers. 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. A cabinet door 2 is provided on the outer side of the box door 1. The cabinet door 2 can be a door panel, and the cabinet door 2 and the surrounding cabinet body can adopt the same material to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinet body, making the coordination between the refrigeration equipment and the surrounding environment better.

[0057] For the sliding module 4, the slide rail 41 can be a C-shaped guide rail, and the sliding member 42 can be a slider. At least part of the sliding member 42 is movably arranged in the chute of the C-shaped guide rail along the extension direction of the C-shaped guide rail.

[0058] For the hanging structure 5, the clamping head 51 and the elastic clamping seat 52 can be configured to be oppositely arranged along the width direction of the box door 1 or the thickness direction of the cabinet door 2 to realize the clamping between the clamping head 51 and the elastic clamping seat 52.

[0059] At the same time, in order to ensure that the clamping head 51 and the elastic clamping seat 52 complete the clamping reliably, the hardness of the clamping head 51 is greater than that of the elastic clamping seat 52; for example, the clamping head 51 can adopt a stainless steel clamping head, and the elastic clamping seat 52 can adopt a plastic clamping seat; during the process of the clamping head 51 clamping to the elastic clamping seat 52, the clamping head 51 squeezes the limiting port, causing the limiting port to expand, and the diameter of the limiting port increases to allow the clamping head 51 to enter into the clamping cavity 5201; after the clamping head 51 completely enters into the clamping cavity 5201, the limiting port will return to its initial size to limit the clamping head 51 from disengaging from the clamping cavity 5201.

[0060] The shape of the limiting port can be circular, rectangular, triangular, etc., and no specific limitation is made thereto. In order to prevent the clamping head 51 from disengaging from the clamping cavity 5201, the maximum outer diameter of the clamping head 51 is greater than the opening size of the limiting port.

[0061] Wherein, when the clamping head 51 and the elastic clamping seat 52 complete the clamping, the elastic clamping seat 52 can be in a deformed state. At this time, the clamping head 51 and the inner wall of the clamping cavity 5201 are clamped in an interference fit manner.

[0062] Of course, in this embodiment, the clamping head 51 can also be set to be adapted to the clamping cavity 5201 on the elastic clamping seat 52 so that when the clamping head 51 and the elastic clamping seat 52 complete the clamping, the elastic clamping seat 52 can also return to its initial state (the state when no clamping head 51 is clamped in the elastic clamping seat 52). At this time, the clamping head 51 is limited in the clamping cavity 5201 of the elastic clamping seat 52.

[0063] As can be seen from the above, by arranging a sliding module 4 and a hanging structure 5 between the cabinet door 1 and the cupboard door 2, the sliding module 4 includes a sliding rail 41 and a sliding member 42 which are slidably arranged. When installing the cupboard door 2, the clamping head 51 and the elastic clamping seat 52 of the hanging structure 5 can be respectively arranged on the sliding member 42 and the cupboard door 2 in advance, and then the sliding rail 41 of the sliding module 4 is connected to the cabinet door 1 to realize the installation of the sliding module 4. Then, by controlling the clamping head 51 to squeeze the elastic clamping seat 52, the clamping between the clamping head 51 and the elastic clamping seat 52 can be realized, so as to conveniently complete the installation of the cupboard door 2, and the cupboard door 2 can slide left and right relative to the cabinet door 1 in the width direction. This way of installing the cupboard door is convenient to operate, reduces the labor intensity of the installers, and improves the installation efficiency of the cupboard door.

[0064] Furthermore, in practical applications, when the refrigeration equipment is installed in the cabinet in an embedded manner, during the process of opening or closing the cabinet door 1, the cupboard door 2 can be moved relative to the cabinet door 1 in the width direction, so as to prevent the cupboard door 2 from touching the surrounding cabinet during the opening and closing process of the cabinet door 1, meeting the normal opening and closing requirements of the cabinet door 1 of the refrigeration equipment.

[0065] In some embodiments, as Figure 4 shown, the clamping head 51 is arranged on one side surface of the sliding member 42 facing the cupboard door 2, and the elastic clamping seat 52 is arranged on one side surface of the cupboard door 2 facing the sliding member 42. This design can minimize the installation gap between the cabinet door 1 and the cupboard door 2 as much as possible.

[0066] Among them, the clamping head 51 and the sliding member 42 can be set as an integral structure, and the elastic clamping seat 52 can be detachably connected to the cupboard door 2 through locking parts such as bolts and rivets.

[0067] Of course, in this embodiment, the elastic clamping seat 52 can also be arranged on one side surface of the sliding member 42 facing the cupboard door 2, and the clamping head 51 can be arranged on one side surface of the cupboard door 2 facing the sliding member 42.

[0068] In some embodiments, as Figure 2 and Figure 3 shown, the clamping head 51 and the limiting port are arranged opposite to each other in the thickness direction of the cupboard door 2, and the clamping head 51 is adapted to the clamping cavity 5201.

[0069] It can be understood that during the installation process of the cupboard door 2, the operator can drive the cupboard door 2 to approach the cabinet door 1 in the thickness direction to realize the clamping between the clamping head 51 and the elastic clamping seat 52.

[0070] During the clamping process of the clamping joint 51 and the elastic clamping seat 52, the clamping joint 51 squeezes the limiting port along the thickness direction of the cabinet door 2. The limiting port expands under the extrusion of the clamping joint 51 to allow the clamping joint 51 to pass through. After the clamping joint 51 enters the clamping cavity 5201, the limiting port contracts to its initial state. At this time, the clamping joint 51 is limited within the clamping cavity 5201, and the clamping joint 51 and the elastic clamping seat 52 complete the clamping. Without being subjected to an external force along the thickness direction again, these two are not easily separated.

[0071] In some embodiments, such as Figure 2 and Figure 3 shown, to facilitate the clamping between the clamping joint 51 and the elastic clamping seat 52, the clamping joint 51 includes a spherical head 510, the clamping cavity 5201 includes a spherical cavity, the spherical head 510 is adapted to the spherical cavity, and the diameter of the limiting port is smaller than the diameter of the spherical head 510.

[0072] It can be understood that by designing the clamping cavity 5201 as a spherical cavity, the stability of the structure of the elastic clamping seat 52 can be ensured, so that the elastic clamping seat 52 can smoothly return to its initial state when being squeezed by the spherical head 510 to limit the spherical head 510 within the spherical cavity.

[0073] Among them, the diameter of the spherical head 510 is the same as the inner diameter of the spherical cavity. The spherical head 510 can be designed as 2 / 3 of the entire sphere, and the inner cavity of the spherical cavity is correspondingly designed as 2 / 3 of the entire sphere. The plane where the limiting port is located is perpendicular to the thickness direction of the cabinet door 2.

[0074] In some embodiments, such as Figure 3 shown, the elastic clamping seat 52 includes a clamping seat body 521 and a fixing ear 522. The clamping seat body 521 is connected to the fixing ear 522. The clamping cavity 5201 is provided in the clamping seat body 521, and the fixing ear 522 is connected to the cabinet door 2.

[0075] Specifically, the fixing ear 522 is provided with a mounting hole, and the fixing ear 522 can be fixed to the cabinet door 2 by a locking bolt or a locking screw passing through the mounting hole.

[0076] Furthermore, to ensure that the elastic clamping seat 52 is reliably fixed to the cabinet door 2, multiple fixing ears 522 can be provided on the elastic clamping seat 52, and the multiple fixing ears 522 are arranged around the clamping seat body 521.

[0077] Optionally, at least two fixing ears 522 can be provided on the fixing ear 522, and at least one fixing ear 522 is arranged on the upper side of the clamping seat body 521 along the height direction of the cabinet door 2.

[0078] For example, there are three fixed ears 522. One of the fixed ears 522 is arranged on the upper side of the card seat body 521 along the height direction of the cabinet door 2, and the other two fixed ears 522 are arranged on the left and right sides of the card seat body 521 along the width direction.

[0079] In some embodiments, in order to ensure that the cabinet door 2 is reliably installed on the box door 1, a plurality of card joints 51 are provided on the sliding member 42, and a plurality of elastic card seats 52 are provided; the plurality of card joints 51 are arranged along the width direction and are arranged opposite to the plurality of elastic card seats 52 one by one.

[0080] In some embodiments, as Figure 2 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, the card joint 51 is connected to the adapter seat 422, and the elastic card seat 52 is connected to the cabinet door 2.

[0081] 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.

[0082] At the same time, the adapter seat 422 and the ball bracket 421 can be connected by welding, and the above-mentioned card joints 51 can be arranged on the adapter seat 422 so as to support the cabinet door 2 through the card joints 51.

[0083] Furthermore, along the extension direction of the slide rail 41, the extension length of the ball bracket 421 can be set to be greater than the extension 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.

[0084] 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 box door 1, a plurality of sets of sliding modules 4 and hanging structures 5 are respectively provided and are arranged opposite to each other one by one. At least one set of sliding modules 4 is arranged between the upper end of the box door 1 and the upper end of the cabinet door 2, and at least one set of sliding modules 4 is arranged between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0085] Specifically, there are four sets of sliding modules 4. Two of the sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the upper end of the box 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 box door 1 and are arranged between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0086] In some embodiments, asFigure 1 and Figure 5 As shown in Figure 5 , the cabinet 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, and the decorative member cover is used to cover the notch end of the groove 101.

[0087] It can be understood that when the cabinet door 2 is installed on the outer side of the cabinet door 1, the sliding module 4 on the cabinet door 1 is connected to the cabinet door 2 through the hanging structure 5. At this time, there is no decorative member at the notch end of the groove 101.

[0088] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the cabinet door 1, the sliding module 4 is no longer used at this time. By covering the decorative member on the notch end of the groove 101, the hidden design of the sliding module 4 can be realized, ensuring the aesthetic appearance of the cabinet door 1.

[0089] In a second aspect, as Figure 5 , Figure 6 and Figure 7 shown, the embodiment of the present utility model 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 cabinet door 1 is rotatably arranged on the box body 3 to open or close the storage compartment.

[0090] 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 the opening and closing states for each storage compartment. Among them, hinges 9 are arranged on the box body 3 on one side corresponding to each storage compartment, and the box body 3 can be rotatably connected to the cabinet door 1 of the door body assembly corresponding to the storage compartment through the hinges 9.

[0091] For each set of door body assemblies, since the cabinet door 2 can move left and right relative to the cabinet door 1 in the width direction, when the refrigeration device is fully embedded, during the process of opening the cabinet door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the cabinet door 1 to avoid the cabinet around the refrigeration device; during the process of closing the cabinet door 1, the cabinet door 2 can be controlled to move towards the side close to the hinge 9 relative to the cabinet door 1 until the cabinet door 2 returns to its original position, ensuring that the side of the cabinet door 1 is flush with the side of the cabinet door 2.

[0092] 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 obtained by all the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0093] In some embodiments, as Figure 6 and Figure 7As shown, the refrigeration device also includes: a sliding door mechanism 6, which is arranged on the cabinet body 3 or the cabinet door 1, and is transmission-connected to the cabinet door 2, and is used to drive the cabinet door 2 to move relative to the cabinet door 1 along the width direction during the opening and closing process of the cabinet door 1; the refrigeration device is configured to be arranged in the accommodating space between the first cabinet body 7 and the second cabinet body 8; during the opening or closing process of the cabinet door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the cabinet door 1 so that the cabinet door 2 avoids the first cabinet body 7 or the second cabinet body 8.

[0094] It is understandable that an opening is provided on the outside of the accommodation space between the first cabinet 7 and the second cabinet 8, and this design allows the cabinet 3 of the refrigeration equipment to be integrally embedded in the accommodation space. In the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism 6 is configured to drive the cabinet door 2 to move in the width direction away from or close to the hinge 9. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet 7 and the second cabinet 8, and avoids the side edges of the cabinet door 2 from interfering with the side walls of the first cabinet 7 and the second cabinet 8, thereby meeting the requirement that the cabinet door 1 can be opened and closed smoothly.

[0095] During the process of opening the cabinet door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance along the width direction toward the side away from the hinge 9, so that the cabinet door 2 can smoothly avoid the side wall of the second cabinet body 8, so that the cabinet door 1 can be fully opened, making it convenient for users to store and retrieve items.

[0096] Similarly, in the process of closing the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance along the width direction toward the side close to the hinge 9. When the cabinet door 1 is completely 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, so that the cabinet door 1 can be completely closed to maintain the overall aesthetics and sealing.

[0097] In this embodiment, the cabinet door 2 is movably arranged on the outside of the cabinet door 1 along the width direction of the cabinet door 1, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the cabinet door 1 during the process of opening or closing the cabinet door 1, so that the cabinet door 1 can avoid the first cabinet body 7 and the second cabinet body 8 on the side during the process of opening and closing, avoiding the interference between the cabinet door 2 and the outside when the cabinet door 1 rotates, and can meet the user's use needs in different scenarios. This design not only improves the convenience of use, but also avoids possible damage to the door body assembly during use. At the same time, this design also allows the refrigeration equipment to be better integrated into the home environment, achieving the effect of overall beauty and sealing.

[0098] In some embodiments, Figure 7 As shown, the sliding door mechanism 6 is connected to the sliding member 42 to drive the sliding member 42 to move along the sliding rail 41 .

[0099] It is understandable that during the opening and closing of the cabinet 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 cabinet door 1, ensuring that the cabinet door 2 does not touch the side cabinet body. This design realizes the integration of the sliding door mechanism 6 and the sliding module 4.

[0100] 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.

[0101] In some embodiments, as Figure 6 and Figure 7 shown, the cabinet door 1 is rotatably connected to the cabinet body 3 through the hinge 9, and the cabinet door 2 can move between a first position and a second position relative to the cabinet door 1 in the width direction; when the cabinet door 2 is in the first position, the cabinet door 1 closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 is close to the hinge 9; when the cabinet door 2 is in the second position, the cabinet door 1 opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 is far from the hinge 9, and the sides of the cabinet door 2 and the cabinet door 1 are misaligned to avoid the side walls of the first cabinet body 7 or the second cabinet body 8.

[0102] It is understandable that the storage compartment is used to store items to be refrigerated or frozen. When the cabinet door 1 closes the storage compartment, the cabinet door 1 is in the 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 equipment. For example, the sides of the cabinet door 2 and the cabinet door 1 are flush. At this time, the cabinet door 2 can completely block the cabinet door 1, ensuring that the cabinet door 2 of the refrigeration equipment exposed in the accommodation space is consistent with the surrounding first cabinet body 7 and second cabinet body 8 in appearance.

[0103] When the cabinet door 1 opens the storage compartment, the cabinet door 1 is in the 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 equipment. For example, the sides of the cabinet door 2 and the cabinet door 1 are misaligned and form a gap that can accommodate the side of the first cabinet body 7 or the second cabinet body 8, so as to avoid collision or interference between the cabinet door 2 and the first cabinet body 7 or the second cabinet body 8 caused by the opening of the cabinet door 1.

[0104] In some embodiments, as Figure 7 shown, the sliding door mechanism 6 includes: a trigger member and a linear drive member. The trigger member is used to obtain the opening and closing signal of the cabinet door 1; the linear drive member is arranged between the cabinet door 1 and the cabinet door 2 and is connected to the trigger member; wherein, the linear drive member is used to drive the cabinet door 2 to move along the width direction of the cabinet door 1 according to the opening and closing signal fed back by the trigger member.

[0105] It is understandable that, for the convenience of controlling the working state of the linear driving member according to the opening and closing signals fed back by the triggering member, the triggering member and the control module can be electrically connected, and the control module and the linear driving member can be electrically connected.

[0106] The triggering member 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 triggering member 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;

[0107] 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 box door 1, and the second end of the linear driving member is connected to the cabinet door 2 to drive the cabinet door 2 to move relative to the box door 1 in the width direction.

[0108] Among them, in the case where the door body assembly includes the above-mentioned sliding module 4 and the hanging structure 5, the linear driving member is arranged on the box door 1. The first end of the linear driving member is connected to the box door 1, and the second end of the linear driving member is connected to the sliding member 42 of the sliding module 4.

[0109] Taking the triggering 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 box door 1 will be specifically described as follows.

[0110] In practical applications, the angle sensor is installed on the hinge axis corresponding to the hinge 9 to monitor the rotation state of the box door 1 relative to the hinge axis. When the box 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 away from the hinge 9 in the width direction of the box door 1; when the box 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 towards the hinge 9 in the width direction of the box door 1.

[0111] Furthermore, as the opening or closing amplitude of the box door 1 is different, the angle sensor can also obtain the rotation angle of the box 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 box door 1, according to the rotation angle when the box 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 box door 1, according to the rotation angle when the box 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 realizes the reset of the cabinet door 2.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Although the present utility model 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 utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
