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.

[0053] Combine the following Figures 1 - 8 , the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0054] In the first aspect, Figure 1 , Figure 5 and Figure 6 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;

[0055] 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;

[0056] The hanging structure 5 includes an elastic clamp 51 and a clamping seat 52, which are respectively arranged on the sliding member 42 and the cabinet door 2. The clamping seat 52 has a clamping groove 520. The elastic clamp 51 can shrink under the pressure of the clamping groove 520 and then be clamped in the clamping groove 520.

[0057] 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.

[0058] 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 cabinet body 3 of the refrigeration equipment, and the cabinet door 1 is rotatably connected to the cabinet body 3 through the hinge 9 to realize the opening or closing of the cabinet door 1 relative to the cabinet body 3. A cabinet door 2 is provided on the outer side of the cabinet 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.

[0059] 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 extending direction of the C-shaped guide rail.

[0060] For the hanging structure 5, the elastic chuck 51 and the clamping seat 52 can be oppositely arranged along the width direction of the cabinet door 1 or the thickness direction of the cabinet door 2 to realize clamping; the clamping seat 52 has a clamping groove 520 adapted to the elastic chuck 51, and the elastic chuck 51 can be embedded into the clamping groove 520 to realize the clamping between the elastic chuck 51 and the clamping seat 52.

[0061] At the same time, in order to ensure that the elastic chuck 51 and the clamping seat 52 complete the clamping reliably, the hardness of the clamping seat 52 is greater than that of the elastic chuck 51; for example, the elastic chuck 51 can be a rubber chuck, and the clamping seat 52 adopts a stainless steel clamping seat; for example, the rubber chuck includes a central column and a rubber sheath, and the rubber sheath is sleeved on the peripheral wall of the central column. The rubber sheath can contract and deform under the extrusion of the clamping groove 520 and return to its original state after leaving the clamping groove 520.

[0062] Since the clamping groove 520 is provided on the clamping seat 52, when the elastic chuck 51 and the clamping seat 52 are oppositely arranged along the width direction of the cabinet door 1 or the thickness direction of the cabinet door 2, the notch of the clamping groove 520 faces the elastic chuck 51 along the above width direction or thickness direction.

[0063] The clamping groove 520 can be configured as a circular groove, and the elastic chuck 51 can be switched from the first state to the second state under the extrusion of the clamping groove 520; when the elastic chuck 51 is in the first state, the maximum outer diameter of the elastic chuck 51 is greater than the inner diameter of the clamping groove 520; when the elastic chuck 51 is in the second state, the maximum outer diameter of the elastic chuck 51 is equal to the inner diameter of the clamping groove 520.

[0064] In this way, under the extrusion of the clamping groove 520, the elastic chuck 51 will gradually contract until it is clamped in the clamping groove 520. At this time, the side wall of the elastic chuck 51 abuts against the groove wall of the clamping groove 520, and there is a relatively large contact friction force between the side wall of the elastic chuck 51 and the groove wall of the clamping groove 520, which can prevent the elastic chuck 51 from disengaging from the clamping groove 520 based on this contact friction force.

[0065] Of course, in this embodiment, engaging structures such as grooves and protrusions can also be provided on the groove walls of the engaging groove 520. When the elastic engaging head 51 can contract under the extrusion of the engaging groove 520, it can also be engaged with the engaging structure, thereby effectively preventing the elastic engaging head 51 from disengaging from the engaging groove 520.

[0066] Obviously, this engaging design in this embodiment facilitates the installation and disassembly of the elastic engaging head 51 and the engaging seat 52, and will not cause damage to the elastic engaging head 51 or the engaging seat 52 during the installation and disassembly process.

[0067] As can be seen from the above, by providing the sliding module 4 and the 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. When installing the cabinet door 2, the elastic engaging head 51 and the engaging 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 box door 1 to realize the installation of the sliding module 4. Then, the engaging seat 52 is used to squeeze the elastic engaging head 51 to engage the elastic engaging head 51 and the engaging seat 52 into one body, thereby conveniently realizing the installation of the cabinet door 2 and ensuring that the cabinet door 2 can move relative to the box door 1 along the width direction of the box door 1.

[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 box door 1, the cabinet door 2 can move relative to the box door 1 along the width direction, avoiding the cabinet door 2 from touching the surrounding cabinets during the opening and closing process of the box door 1, and preferably meeting the opening and closing requirements of the box door 1 of the refrigeration equipment.

[0069] In some embodiments, as Figure 1 、 Figure 2 and Figure 5 shown, the elastic engaging head 51 is arranged on the side surface of the sliding member 42 facing the cabinet door 2, and the engaging seat 52 is arranged on the side surface of the cabinet door 2 facing the sliding member 42. This design can minimize the installation gap between the box door 1 and the cabinet door 2 as much as possible.

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

[0071] Of course, in this embodiment, the engaging seat 52 can also be arranged on the side surface of the sliding member 42 facing the cabinet door 2, and the elastic engaging head 51 can be arranged on the side surface of the cabinet door 2 facing the sliding member 42.

[0072] In some embodiments, as Figure 5 shown, the elastic engaging head 51 and the engaging seat 52 are oppositely arranged along the thickness direction of the cabinet door 2 and can be engaged along the thickness direction.

[0073] It can be understood that since the elastic chuck 51 and the clamping seat 52 are oppositely arranged along the thickness direction of the cabinet door 2, the clamping seat 52 can be controlled to approach the elastic chuck 51 along the thickness direction, so as to use the clamping seat 52 to squeeze the elastic chuck 51 until the elastic chuck 51 deforms and is clamped in the clamping structure of the clamping seat 52.

[0074] In some embodiments, as Figure 2 shown, the elastic chuck 51 includes a base 511 and a deformable portion 512; the first end of the base 511 is arranged on the sliding member 42 or the cabinet door 2, the second end of the base 511 is connected to the deformable portion 512, and the deformable portion 512 is used for being clamped in the clamping groove 520.

[0075] It can be understood that the base 511 can be a rigid seat body. For example, the base 511 is an iron seat body or a copper seat body. This design facilitates the reliable fixation of the base 511 on the sliding member 42 or the cabinet door 2, and the elastic chuck 51 can play a supporting role for the clamping seat 52 based on the base 511. Among them, both the base 511 and the deformable portion 512 can extend into the clamping groove 520, which enables the base 511 to be supported on the top groove wall of the clamping groove 520.

[0076] At the same time, the deformable portion 512 can be made of plastic or rubber. When the deformable portion 512 is inserted into the clamping groove 520, since the maximum outer diameter of the deformable portion 512 is greater than the inner diameter of the clamping groove 520, the deformable portion 512 will gradually contract under the extrusion of the groove wall of the clamping groove 520 until the maximum outer diameter of the deformable portion 512 matches the inner diameter of the clamping groove 520, so as to realize clamping the deformable portion 512 in the clamping groove 520.

[0077] Furthermore, the deformable portion 512 includes a plurality of petal-shaped protrusions, and the plurality of petal-shaped protrusions are arranged at intervals along the circumferential direction on the base 511; among them, the plurality of petal-shaped protrusions can approach each other under the extrusion of the clamping groove 520 and then be clamped in the clamping groove 520.

[0078] It can be understood that the base 511 is columnar, and the plurality of petal-shaped protrusions are circumferentially uniformly distributed relative to the central axis of the base 511 at the second end of the base 511, and each petal-shaped protrusion is petal-shaped. For example, when there are four petal-shaped protrusions, the shape of each petal-shaped protrusion can be 1 / 4 of a columnar body.

[0079] Since the petal-shaped protrusions are separated from each other, each petal-shaped protrusion has a relatively good elastic modulus with respect to the base 511. This enables, when the elastic chuck 51 is in the first state, the circumferential spacing between any two adjacent petal-shaped protrusions to be a first spacing; when the elastic chuck 51 is in the second state, the circumferential spacing between any two adjacent petal-shaped protrusions to be a second spacing, and the second spacing is smaller than the first spacing. Thus, under the extrusion of the clamping groove 520, the multiple petal-shaped protrusions will move closer to each other, that is, the elastic chuck 51 can contract under the extrusion of the clamping groove 520 and then be clamped in the clamping groove 520.

[0080] In some embodiments, as Figure 3 and Figure 4 shown, to facilitate guiding the elastic chuck 51 to contract and deform under the extrusion of the clamping groove 520, the clamping groove 520 includes a guiding section 5201 and a clamping section 5202; the guiding section 5201 and the clamping section 5202 are in communication; the guiding section 5201 is used to guide the elastic chuck 51 into the clamping groove 520 and move towards the clamping section 5202; the clamping section 5202 is used to clamp the elastic chuck 51.

[0081] It can be understood that the guiding section 5201 can be configured with an inclined surface or an arc surface to guide the elastic chuck 51 into the clamping groove 520 based on the inclined surface or the arc surface; the clamping section 5202, as the part for clamping the elastic chuck 51, when the elastic chuck 51 is clamped in the clamping section 5202, the elastic chuck 51 undergoes a contraction deformation, and the peripheral wall of the elastic chuck 51 abuts against the groove wall corresponding to the clamping section 5202.

[0082] Further, to facilitate guiding the elastic chuck 51 into the elastic chuck 51 and ensure that the elastic chuck 51 undergoes a contraction deformation during the process of entering the clamping section 5202, it can be set that the first end of the guiding section 5201 is for the elastic chuck 51 to enter, the second end of the guiding section 5201 is in communication with one end of the clamping section 5202; the inner diameter of the guiding section 5201 gradually decreases from the first end to the second end.

[0083] Among them, the guiding section 5201 and the clamping section 5202 are coaxially arranged, the maximum outer diameter of the elastic chuck 51 in the first state is smaller than the inner diameter of the first end of the guiding section 5201 and larger than the inner diameter of the second end of the guiding section 5201.

[0084] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 shown, the clamping seat 52 includes a clamping seat body 521 and a fixing ear 522, the clamping seat body 521 and the fixing ear 522 are connected, and the clamping groove 520 is arranged on the clamping seat body 521; when the elastic chuck 51 is arranged on the sliding member 42, the fixing ear 522 is connected to the cabinet door 2.

[0085] 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.

[0086] Further, in order to ensure that the clamping seat 52 is reliably fixed to the cabinet door 2, the clamping seat 52 can be provided with a plurality of fixing ears 522, and the plurality of fixing ears 522 are arranged around the clamping seat body 521.

[0087] Optionally, at least two fixing ears 522 can be provided, 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.

[0088] For example, three fixing ears 522 are provided, one of which is arranged on the upper side of the clamping seat body 521 along the height direction of the cabinet door 2, and the other two fixing ears 522 are arranged on the left and right sides of the clamping seat body 521 along the width direction.

[0089] In some embodiments, in order to ensure that the cabinet door 2 is reliably installed on the box door 1, a plurality of elastic clamping heads 51 can be provided on the sliding member 42, and a plurality of clamping seats 52 are provided; the plurality of elastic clamping heads 51 are arranged in the width direction and are arranged in one-to-one correspondence with the plurality of clamping seats 52.

[0090] In some embodiments, 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 elastic clamping head 51 is connected to the adapter seat 422, and the clamping seat 52 is connected to the cabinet door 2.

[0091] It can be understood that the slide rail 41 can be a C-shaped rail, and a rolling fit can be used 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.

[0092] At the same time, the adapter seat 422 and the ball bracket 421 can be connected by welding, and the above-mentioned elastic clamping head 51 can be provided on the adapter seat 422 so as to support the cabinet door 2 through the elastic clamping head 51.

[0093] Further, 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.

[0094] In some embodiments, such as Figure 1As shown, in order to ensure the stability and reliability of the movement of the cabinet door 2 relative to the box door 1, multiple sets of sliding modules 4 and hanging structures 5 are respectively provided and arranged in a one-to-one correspondence. At least one set of sliding modules 4 is provided 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 provided between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0095] Specifically, four sets of sliding modules 4 are provided. Two of the sliding modules 4 are arranged along the width direction of the box door 1 and are provided between the upper end of the box door 1 and the upper end of the cabinet door 2. The other two sets of sliding modules 4 are arranged along the width direction of the box door 1 and are provided between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0096] In some embodiments, as Figure 1 and Figure 6 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.

[0097] It can be understood that 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, no decorative member is provided at the notch end of the groove 101.

[0098] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the box door 1, at this time the sliding module 4 is no longer used. 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 box door 1.

[0099] 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 box door 1 is rotatably arranged on the box body 3 to open or close the storage compartment.

[0100] 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, a hinge 9 is provided on the box body 3 on the side 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.

[0101] 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 equipment is fully embedded, during the process of opening the box door 1, the cabinet door 2 can be controlled to move relative to the box door 1 toward the side away from the hinge 9 to avoid the cabinet body around the refrigeration equipment; during the process of closing the box door 1, the cabinet door 2 can be controlled to move relative to the box door 1 toward the side close to the hinge 9 until the cabinet door 2 returns to its original position to ensure that the side of the box door 1 is flush with the side of the cabinet door 2.

[0102] Since the refrigeration equipment includes a door body assembly, the specific structure of the door body assembly refers to the above embodiment, and the refrigeration equipment shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0103] In some embodiments, Figure 7 and Figure 8 As 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] In this embodiment, the cabinet door 2 is movably arranged on the outside of the box door 1 along 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 process 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, avoiding 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 equipment to better integrate into the home environment, achieving the effects of overall aesthetics and sealing.

[0108] In some embodiments, 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.

[0109] It can be understood that during the opening and closing process of the box door 1, the sliding door mechanism 6 drives the sliding member 42 to move relative to the slide rail 41 along 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 touch the cabinet body on the side. This design realizes the integration of the sliding door mechanism 6 and the sliding module 4.

[0110] 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.

[0111] 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 relative to the box door 1 along the width direction; 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 is 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 body 7 or the second cabinet body 8.

[0112] 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 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 side of the cabinet door 2 and the side of the box door 1 are flush, and at this time, the cabinet door 2 can completely cover the box 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.

[0113] When the door of the storage compartment is opened, the door 1 of the box is in an open state. 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 a gap is formed that can accommodate the side of the first cabinet 7 or the second cabinet 8, so as to prevent the cabinet door 2 from colliding with or interfering with the first cabinet 7 or the second cabinet 8 due to the opening of the box door 1.

[0114] In some embodiments, as Figure 8 shown, the sliding door mechanism 6 includes: a triggering member and a linear driving member. The triggering member is used to obtain the opening and closing signal of the box door 1; the linear driving member is arranged between the box door 1 and the cabinet door 2 and is connected to the triggering member; wherein, the linear driving member 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 triggering member.

[0115] It can be understood that, in order to facilitate controlling the working state of the linear driving member according to the opening and closing signal fed back by the triggering member, the triggering member can be electrically connected to the control module, and the control module and the linear driving member are electrically connected.

[0116] The triggering member can be a photoelectric switch, and the photoelectric switch 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;

[0117] The linear driving member can be a telescopic rod such as a cylinder or an electric push rod. The linear driving member extends along 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 realize driving the cabinet door 2 to move relative to the box door 1 along the width direction.

[0118] 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 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.

[0119] Taking the triggering member as an angle sensor as an example below, the control of the linear driving member on the cabinet door 2 during the opening and closing process of the box door 1 will be specifically described as follows.

[0120] In practical applications, the angle sensor is installed on the hinge shaft corresponding to the hinge 9 to monitor the rotation state of the box door 1 relative to the hinge shaft. 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 along 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 along the width direction of the box door 1.

[0121] Furthermore, as the opening or closing amplitude of the box door 1 varies, the angle sensor can also obtain the rotation angle of the box 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 box door 1, according to the rotation angle when the box 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 box door 1, according to the rotation angle when the box 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 the reset of the cabinet door 2 is achieved.

[0122] 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.
