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

[0056] The following is combined with Figures 1-11, the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0057] In the first aspect, Figure 1 , Figure 8 and Figure 9 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;

[0058] 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;

[0059] The hanging structure 5 includes a clamping joint 51 and an elastic clamping seat 52, which are respectively arranged on the sliding member 42 and the cabinet door 2. The elastic clamping seat 52 has a clamping groove 520 and a notch 5201 and an embedding opening 5202 communicating with the clamping groove 520, and the notch 5201 and the embedding opening 5202 are connected; the clamping joint 51 can be clamped in the clamping groove 520 from the embedding opening 5202, and one end of the clamping joint 51 away from the elastic clamping seat 52 is inserted into the notch 5201;

[0060] 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.

[0061] 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.

[0062] 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.

[0063] For the hanging structure 5 , the elastic clamping seat 52 has a clamping groove 520 adapted to the clamping joint 51 , and the clamping joint 51 can be embedded in the clamping groove 520 through the embedding opening 5202 to achieve the clamping connection between the clamping joint 51 and the elastic clamping seat 52 .

[0064] To ensure that the card connector 51 and the elastic card seat 52 complete the card connection reliably, the hardness of the card connector 51 is greater than that of the elastic card seat 52. For example, the card connector 51 can be a stainless-steel card connector, and the elastic card seat 52 can be a plastic card seat. The card connector 51 can be arranged opposite to the insertion port 5202 along the width direction of the cabinet door 1 to achieve card connection with the card slot 520 of the elastic card seat 52 along the width direction. The card connector 51 can also be arranged opposite to the insertion port 5202 along the thickness direction of the cabinet door 1 to achieve card connection with the card slot 520 of the elastic card seat 52 along the thickness direction.

[0065] Among them, when the card connector 51 and the elastic card seat 52 complete the card connection, the elastic card seat 52 can be in a deformed state. At this time, the card connector 51 and the elastic card seat 52 are connected in an interference fit manner.

[0066] Of course, it is also possible to set the card connector 51 to be adapted to the card slot 520 on the elastic card seat 52, so that when the card connector 51 and the elastic card seat 52 complete the card connection, the elastic card seat 52 can also return to the initial state (the state when the card connector 51 is not connected in the elastic card seat 52). At this time, the card connector 51 is limited in the card slot 520 of the elastic card seat 52.

[0067] As can be seen from the above, by arranging the sliding module 4 and the hanging structure 5 between the cabinet door 1 and the cabinet door 2, the sliding module 4 includes a sliding rail 41 and a sliding member 42 arranged in a sliding manner. When installing the cabinet door 2, the card connector 51 and the elastic card seat 52 of the hanging structure 5 can be respectively arranged on the sliding member 42 and the cabinet 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, control the card connector 51 to enter the card slot 520 from the insertion port 5202, so as to realize the card connection between the card connector 51 and the elastic card seat 52, and thus conveniently complete the installation of the cabinet door 2, realizing that the cabinet door 2 can slide left and right relative to the cabinet door 1 along the width direction. This cabinet door installation method is convenient to operate, reduces the labor intensity of the installation personnel, and improves the installation efficiency of the cabinet door.

[0068] Furthermore, in practical applications, when the refrigeration equipment is installed in an embedded manner relative to the cabinet, during the process of opening or closing the cabinet door 1, the cabinet door 2 can be moved relative to the cabinet door 1 along the width direction, avoiding the cabinet door 2 touching the surrounding cabinets during the opening and closing process of the cabinet door 1, and meeting the normal opening and closing requirements of the cabinet door 1 of the refrigeration equipment.

[0069] In some embodiments, such as Figure 2 and Figure 4As shown, the card connector 51 is provided on one side of the sliding member 42 facing the cabinet door 2, and the elastic card seat 52 is provided on one side of the cabinet door 2 facing the sliding member 42. This design not only facilitates the installation of the cabinet door but also can minimize the installation gap between the box door 1 and the cabinet door 2 as much as possible. When the card connector 51 is engaged in the card slot 520, the end of the card connector 51 facing the sliding member 42 penetrates through the notch 5201.

[0070] Among them, the card connector 51 and the sliding member 42 can be set as an integral structure, and the elastic card seat 52 can be detachably connected to the cabinet door 2 through locking members such as bolts and rivets.

[0071] Of course, in this embodiment, the elastic card seat 52 can also be provided on one side of the sliding member 42 facing the cabinet door 2, and the card connector 51 can be provided on one side of the cabinet door 2 facing the sliding member 42.

[0072] In some embodiments, as Figure 2 、 Figure 3 and Figure 8 shown, the card slot 520 and the notch 5201 both extend along the width direction of the box door 1. The insertion opening 5202 is provided at one end of the card slot 520 along the width direction. The card connector 51 is adapted to the card slot 520 and can be engaged in the card slot 520 along the width direction; the card connector 51 is vertically limited between the upper side wall and the lower side wall of the card slot 520.

[0073] It can be understood that by setting the card slot 520 to extend along the width direction, it is convenient to control the relative movement of the card connector 51 and the card slot 520 along the width direction, so as to realize the extrusion of the elastic card seat 52 by the card connector 51 along the width direction and then engage with the elastic card seat 52. When the card connector 51 is engaged in the card slot 520, the card connector 51 is vertically limited between the upper side wall and the lower side wall of the card slot 520. This design can prevent the card connector 51 from disengaging from the card slot 520 under the action of vertical pressure or tension, ensuring the reliability of the engagement between the card connector 51 and the elastic card seat 52, and thus using the card connector 51 and the elastic card seat 52 to form a hanging structure 5 to connect the sliding module 4 and the cabinet door 2.

[0074] When the card connector 51 is fixed on the sliding member 42, the end of the card connector 51 away from the bottom of the card slot 520 is connected to the sliding member 42. By configuring the card slot 520 with the notch 5201 and the insertion opening 5202, it is convenient to control the card connector 51 to enter the card slot 520 from the insertion opening 5202 along the width direction, and it is possible to control the relative movement of the card connector 51 along the width direction with respect to the card slot 520 until the card connector 51 is engaged in the set position within the card slot 520.

[0075] Optionally, the cross-sectional shape of the clamping joint 51 along the vertical plane may be a rectangle, and the clamping groove 520 is a rectangular groove adapted to the clamping joint 51 .

[0076] Optionally, in order to effectively prevent the clamping joint 51 from being disengaged from the clamping groove 520 , the cross-sectional shape of the clamping joint 51 along the vertical plane may be an isosceles trapezoid, and the clamping groove 520 is a dovetail groove adapted to the shape of the clamping joint 51 .

[0077] In some embodiments, Figure 3 As shown, the snap-in slot 520 includes a guide section 5211 and a snap-in section 5212; the guide section 5211 and the snap-in section 5212 are connected; the guide section 5211 is used to guide the snap-in connector 51 to enter the snap-in slot 520 and move toward the snap-in section 5212; the snap-in section 5212 is adapted to the snap-in connector 51 and is used to realize the snap-in connection of the snap-in connector 51.

[0078] It can be understood that the snap-in slot 520 has a slot 5201 and an embedding opening 5202, the guide section 5211 and the snap-in section 5212 can be configured to be connected along the width direction, the slot 5201 is extended along the extension direction of the guide section 5211 and the snap-in section 5212, the embedding opening 5202 is located at the end of the guide section 5211 away from the snap-in section 5212, and the end of the snap-in section 5212 away from the guide section 5211 can be designed to be sealed.

[0079] like Figure 5 As shown, when the clamping connector 51 is clamped into the clamping slot 520, the clamping connector 51 is first set at a position corresponding to the embedding opening 5202 of the clamping slot 520, and then moved toward the inside of the clamping slot 520 along the width direction.

[0080] like Figure 6 As shown, the clamping joint 51 is located at the guiding section 5211 of the clamping groove 520 , and at this time, the guiding section 5211 guides the clamping joint 51 to move toward the clamping section 5212 of the clamping groove 520 along the width direction.

[0081] like Figure 7 As shown, as the card connector 51 continues to move forward along the width direction, the card connector 51 reaches the card connector section 5212 of the card connector groove 520. Since the card connector section 5212 is adapted to the card connector 51, the card connector 51 will no longer move relative to the card connector groove 520, thereby completing the card connector 51 based on the card connector groove 520.

[0082] Furthermore, if Figure 3 and Figure 8As shown, the first end of the guide section 5211 is used for the entry of the card connector 51, and the second end of the guide section 5211 is connected to one end of the card connection section 5212; the slot width of the guide section 5211 gradually decreases from the first end to the second end, and the slot width of the card connection section 5212 is smaller than the slot width of the first end of the guide section 5211, and larger than the slot width of the second end of the guide section 5211.

[0083] It is understandable that the width of the end of the clamping joint 51 facing the sliding member 42 is smaller than the width of the notch at the first end of the guide section 5211, and larger than the width of the notch at the second end of the guide section 5211. In this way, when the clamping joint 51 moves along the guide section 5211 toward the clamping section 5212, the clamping joint 51 will gradually squeeze the notch 5201 of the guide section 5211 until the clamping joint 51 enters the clamping section 5212.

[0084] Since the clamping section 5212 is adapted to the clamping joint 51, the slot width of the clamping section 5212 is adapted to the width of the end of the clamping joint 51 toward the sliding member 42. When the clamping joint 51 enters into the clamping section 5212, the clamping joint 51 is limited along the width direction between the end of the clamping section 5212 toward the guide section 5211 and the end of the clamping section 5212 away from the guide section 5211. The clamping joint 51 will not move relative to the clamping section 5212 along the width direction and the vertical direction.

[0085] In some embodiments, Figure 4 As shown, the elastic holder 52 includes a holder body 521 and a fixing ear 522 , the holder body 521 and the fixing ear 522 are connected, the engaging groove 520 is provided on the holder body 521 , and the fixing ear 522 is connected to the cabinet door 2 .

[0086] Specifically, a mounting hole is provided on the fixing ear 522 , 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.

[0087] Furthermore, in order to ensure that the elastic holder 52 is reliably fixed to the cabinet door 2 , the elastic holder 52 may be provided with a plurality of fixing ears 522 , and the plurality of fixing ears 522 are arranged around the holder body 521 .

[0088] Optionally, at least two fixing ears 522 may be provided, and at least one fixing ear 522 is provided on the upper side of the holder body 521 along the height direction of the cabinet door 2 .

[0089] For example, three fixing ears 522 are provided, one of which is provided on the upper side of the card holder body 521 along the height direction of the cabinet door 2, and the other two fixing ears 522 are provided on the left and right sides of the card holder body 521 along the width direction.

[0090] 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 in the vertical direction and are arranged opposite to the plurality of elastic card seats 52 one by one.

[0091] 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 in the width direction, the adapter seat 422 is connected to the ball bracket 421, the card joint 51 is arranged on the adapter seat 422, and the elastic card seat 52 is arranged on the cabinet door 2.

[0092] It can be understood that the slide rail 41 can be a C-shaped rail, and a rolling fit can be utilized between the ball bracket 421 and the slide rail 41 by means of 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.

[0093] At the same time, the adapter seat 422 and the ball bracket 421 can be connected by welding, and the card joint 51 shown in the above embodiments can be arranged on the adapter seat 422 so as to support the cabinet door 2 through the card joint 51.

[0094] Further, 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 force 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.

[0095] 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.

[0096] Specifically, four sets of sliding modules 4 are provided, two of which 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.

[0097] In some embodiments, as Figure 1 and Figure 9 shown, the box 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.

[0098] Understandably, when the cabinet door 2 is installed on the outer side of the box door 1, the sliding module 4 on the box door 1 is connected to the cabinet door 2 through the hanging structure 5. At this time, there is no decorative piece at the notch end of the groove 101.

[0099] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the box door 1, the sliding module 4 is no longer used at this time. By covering the decorative piece 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 box door 1.

[0100] In a second aspect, as Figure 9 、 Figure 10 and Figure 11 shown, the 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 box door 1 is rotatably provided on the box body 3 to open or close the storage compartment.

[0101] Understandably, 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, a hinge 9 is provided on one side of the box body 3 corresponding to each storage compartment, and the box body 3 can be rotatably connected to the box door 1 of the door body assembly corresponding to the storage compartment through the hinge 9.

[0102] For each set of door body assemblies, since the cabinet door 2 can move left and right relative to the box door 1 in the width direction, when the refrigeration device is fully embedded, during the process of opening the box door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the box door 1 to avoid the cabinet around the refrigeration device; during the process of closing the box door 1, the cabinet door 2 is controlled to move towards the side close to the hinge 9 relative to the box door 1 until the cabinet door 2 returns to its original position, ensuring that the side of the box door 1 is flush with the side of the cabinet door 2.

[0103] Since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiment, the refrigeration device shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0104] In some embodiments, as Figure 10 and Figure 11As 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.

[0105] 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 direction away from or close to the hinge 9 along the width direction. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet 7 and the second cabinet 8, avoids interference between the cabinet door 2 and the side walls of the first cabinet 7 and the second cabinet 8, and meets the requirement that the cabinet door 1 can be opened and closed smoothly.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] In some embodiments, Figure 11 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 .

[0110] It is understandable that during the opening and closing process 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 utilized 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.

[0111] 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.

[0112] In some embodiments, as Figure 10 and Figure 11 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 approaches 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 moves away from the hinge 9, and the sides of the cabinet door 2 and the cabinet door 1 are offset to avoid the side walls of the first cabinet body 7 or the second cabinet body 8.

[0113] 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 cover the cabinet door 1, ensuring that the cabinet door 2 of the refrigeration equipment exposed in the accommodating space is consistent with the surrounding first cabinet body 7 and second cabinet body 8 in appearance.

[0114] 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 offset, and a gap is formed 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.

[0115] In some embodiments, as Figure 11 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; among them, 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.

[0116] It is understandable that, for the convenience of controlling the working state of the linear drive member according to the opening and closing signals fed back by the triggering member, the triggering member can be electrically connected to the control module, and the control module can be electrically connected to the linear drive member.

[0117] The triggering member can be a photoelectric switch, which judges the opening and closing state of the door 1 by detecting the distance change of the 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 door 1 by detecting the angle change of the door 1 relative to the box body 3;

[0118] The linear drive member can be a telescopic rod such as a cylinder or an electric push rod. The linear drive member extends along the width direction. The first end of the linear drive member is connected to the door 1, and the second end of the linear drive member is connected to the cabinet door 2 to drive the cabinet door 2 to move relative to the door 1 along the width direction.

[0119] Among them, in the case where the door body assembly includes the above-mentioned sliding module 4 and the hanging structure 5, the linear drive member is arranged on the door 1. The first end of the linear drive member is connected to the door 1, and the second end of the linear drive member is connected to the sliding member 42 of the sliding module 4.

[0120] Taking the triggering member as an angle sensor as an example below, the control of the cabinet door 2 by the linear drive member during the opening and closing process of the door 1 will be specifically described as follows.

[0121] In practical applications, the angle sensor is installed on the hinge axis corresponding to the hinge 9 to monitor the rotation state of the door 1 relative to the hinge axis. When the door 1 is opened, the angle sensor feeds back an opening signal to the linear drive member, and the linear drive member drives the cabinet door 2 to move away from the hinge 9 along the width direction of the door 1; when the door 1 is closed, the angle sensor feeds back a closing signal to the linear drive member, and the linear drive member drives the cabinet door 2 to move towards the hinge 9 along the width direction of the door 1.

[0122] Furthermore, as the opening or closing amplitude of the door 1 is different, the angle sensor can also obtain the rotation angle of the door 1. The linear drive member can determine the preset value of the movement according to the rotation angle. During the opening process of the door 1, according to the rotation angle when the door 1 is opened, the stroke of the telescopic end of the linear drive member is determined, and then the linear drive 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 door 1, according to the rotation angle when the door 1 is closed, the stroke of the telescopic end of the linear drive member is determined, and then the linear drive 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.

[0123] 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 substitutions 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.
