[0117] In some embodiments, the sliding door mechanism 7 of this embodiment can be set on the box door 2, one of the first slider 714 and the second slider 713 is transmission-connected to the box door 2 or the box body 1, and the other is slidingly connected to the door panel 21 set on the outside of the box door 2, so that when the box door 2 rotates, the first slider 714 and the second slider 713 slide relative to each other to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid obstacles on both sides during the process of turning the box door 2 open and close.

[0118] Specifically, taking the example of a first slider 714 connected to the housing 1 via a traction member and a second slider 713 connected to the door panel 21, the first base 717 of this embodiment can be disposed on the door 2. The ends of the flexible cable 706 are respectively connected to the first slider 714 and the second slider 713, so that the first slider 714 can pull the second slider 713 to move synchronously via the flexible cable 706, thereby driving the door panel 21 to slide relative to the door 2.

[0119] By properly setting the extension direction of the flexible cable 706 , the first slider 714 and the second slider 713 move in opposite directions during movement, thereby driving the door panel 21 to avoid obstacles.

[0120] For example, when the door 2 is rotated to open outside the housing 1, the door 1 drives the first slider 714 to slide toward the first hinge 4 via the traction component. At the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., away from the first hinge 4) via the flexible cable 706, thereby preventing the door panel 21 from interfering with an obstacle outside. When the door 2 is rotated to close toward the housing 1, the housing 1 drives the first slider 714 to slide away from the first hinge 4. At the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., toward the first hinge 4) via the flexible cable 706, thereby preventing the door panel 21 from interfering with an obstacle after closing.

[0121] In some embodiments, the first slider 714 can also be connected to the door panel 21. Correspondingly, the second slider 713 is connected to the box door 2 or the box body 1 through a traction component. The working process is the same as the above embodiment and will not be repeated here.

[0122] According to the sliding door mechanism 7 of the present application, a first guide rail and a second guide rail are arranged on both sides of the first base 717, and a first slider 714 and a second slider 713 are slidably arranged on the first guide rail and the second guide rail, respectively. The first slider 714 and the second slider 713 can slide synchronously along the guide rails under the transmission of the flexible rope 706, and the sliding directions are opposite. One of the first slider 714 and the second slider 713 is connected to the box door 2 or the box body 1 through a traction component, and the other is connected to the door panel 21 arranged on the outside of the box door 2, so that when the box door 2 rotates, the two sliders slide relative to each other to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid obstacles on both sides during the process of turning the box door 2 on and off.

[0123] It should be noted that, in actual applications, the designs of the first slider 714 and the second slider 713 can be flexible and adaptable to different working scenarios and performance requirements. They are not limited to specific shapes, sizes or materials, but can be customized and optimized according to specific needs.

[0124] From a material perspective, the first slider 714 and the second slider 713 can be made of materials with high wear resistance, low friction coefficient, and good stability, such as metal alloys, engineering plastics, or special lubricating materials. These materials are selected to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0125] In terms of structural design, the first and second sliders 714, 713 can utilize various guide rail contact surfaces, such as flat contact, ball contact, or sliding bearing contact. Each of these contact methods has its own advantages and disadvantages. For example, ball contact reduces friction and wear, but is more expensive; flat contact, on the other hand, offers a simpler structure but may require more frequent lubrication and maintenance. Therefore, the selection process should comprehensively consider factors such as usage conditions, cost-effectiveness, and ease of maintenance.

[0126] Furthermore, to enhance the load-bearing capacity and stability of the sliders, reinforcing ribs, support plates, or other auxiliary structures may be added to the first slider 714 and the second slider 713. These structures can increase the rigidity and deformation resistance of the sliders, ensuring stable sliding performance when bearing the weight of the door panel 21 and external forces.

[0127] In this embodiment, the first guide rail and the second guide rail are arranged in sequence along the width direction of the first base 717, and the first guide rail and the second guide rail are arranged parallel to the width direction of the first base 717. While ensuring that the length of the first guide rail and the second guide rail can meet the sliding distance of the first slider 714 and the second slider 713, the dimensions of the first base 717 in the height direction and the thickness direction can be effectively reduced, and the structure is more compact and occupies less space.

[0128] In actual applications, due to factors such as machine tool accuracy, tool wear, and material unevenness, there will be certain errors in the processing of the first guide rail, the second guide rail, and the base. These errors may include dimensional errors (such as deviations in length, width, and height), shape errors (such as straightness, flatness, roundness, etc.), and position errors (such as coaxiality, parallelism, and perpendicularity). The parallelism between the first and second guide rails is evaluated by measuring the relative position deviation between them. This deviation needs to be controlled within a certain tolerance range to ensure smooth sliding of the slider and stable operation of the system. This tolerance range is usually determined based on design requirements, usage environment, and system accuracy.

[0129] It should be noted that in this embodiment, parallelism and verticality should not be strictly defined in a geometric sense. At least the manufacturing and installation errors should be considered, and the error of plus or minus 10° should be understood as within the scope of protection of the patent.

[0130] In one embodiment of the present application, as shown in Figures 3, 4, and 5, the flexible cable 706 includes a first flexible cable and a second flexible cable. The first flexible cable passes around the first end of the first base 717, and its two ends are respectively connected to one end of the first slider 714 and the second slider 713; the second flexible cable passes around the second end of the first base 717, and its two ends are respectively connected to the second ends of the first slider 714 and the second slider 713.

[0131] In this embodiment, the first end of the first flexible cable is connected to the first slider 714 and the second slider 713 by passing the first flexible cable around the first base 717. When the first slider 714 is driven by the door 2 or the box body 1 to slide in the direction away from the first end of the first base 717 through the traction component, the first slider 714 drives the second slider 713 to slide in the direction close to the first end of the first base 717 through the first flexible cable. At the same time, the second end of the second flexible cable is connected to the first slider 714 and the second slider 713 by passing the second flexible cable around the first base 717. When the first slider 714 slides toward the other end away from the first base 717 under the drive of the box door 2, the first slider 714 drives the second slider 713 to slide toward the other end close to the first base 717 through the second flexible rope, thereby achieving that when the first slider 714 slides toward both ends of the first base 717 respectively, it can drive the second slider 713 and the first slider 714 to slide in the opposite direction, thereby enabling the door panel 21 to slide relative to the box door 2 as the box door 2 rotates when the box door 2 is opened and closed, so as to avoid interference with obstacles and affecting the opening and closing of the box door 2.

[0132] Flexible rope 706 can be made of steel wire rope, steel strand, or hemp rope. The choice depends on the load, operating environment, and intended use. For applications requiring heavy loads and harsh environments, steel wire rope or steel strand is recommended; for applications with lighter loads and milder environments, hemp rope can be considered. While meeting the intended use, consider the cost differences between different materials and choose the most cost-effective one. Furthermore, steel wire rope and steel strand may require regular inspection and maintenance during use to ensure performance and safety; hemp rope, on the other hand, is relatively easy to replace and maintain.

[0133] Specifically, the second slider 713 and the first slider 714 are both provided with a connector 711 for fixing the flexible cable 706 .

[0134] In one embodiment of the present application, as shown in Figures 3, 4 and 5, the sliding door mechanism 7 also includes: a first fixed seat 701 and a second fixed seat 702, the first fixed seat 701 is connected to the first end of the first base 717, forming a first limiting groove, the two ends of the first limiting groove are connected to the first ends of the first guide rail and the second guide rail, and a part of the first flexible rope is slidably set in the first limiting groove; the second fixed seat 702 is connected to the second end of the first base 717, forming a second limiting groove, the two ends of the second limiting groove are connected to the second ends of the first guide rail and the second guide rail, and a part of the second flexible rope is slidably set in the second limiting groove.

[0135] In this embodiment, a first fixing seat 701 and a second fixing seat 702 are respectively provided at both ends of the first base 717, and the first fixing seat 701 and the second fixing seat 702 are respectively formed with a first limiting groove and a second limiting groove docking with the first guide rail and the second guide rail, respectively limiting and guiding the positions of the first flexible rope and the second flexible rope, so that the sliding of the first flexible rope and the second flexible rope is smoother.

[0136] Specifically, a first fixing hole is provided on the first fixing seat 701, and a first waist-shaped hole extending along the width direction of the first base 717 is provided on the first base 717; the sliding door mechanism 7 also includes a first adjusting member 704, which passes through the first fixing hole and is slidably arranged in the first waist-shaped hole to adjust the tightness of the first flexible rope by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0137] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the first fixing seat 701 can be adjusted along the width direction of the first base 717, so that the first fixing seat 701 can tighten or loosen the first flexible rope, thereby adjusting the tightness of the first flexible rope.

[0138] Since the first flexible cable and the second flexible cable are respectively located on the first fixing seat 701 and the second fixing seat 702 on both sides of the first base 717, and the first flexible cable and the second flexible cable are connected to the first slider 714 and the second slider 713 at both ends, when the first fixing seat 701 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the first flexible cable is adjusted in tightness accordingly, and the second flexible cable is also adjusted in tightness accordingly under the pulling of the first fixing seat 701 on the first flexible cable.

[0139] In some embodiments, a first fixing hole can also be set on the second fixing seat 702; a first waist-shaped hole extending along the width direction of the first base 717 is provided on the first base 717; the sliding door mechanism 7 also includes a first adjusting member 704, the first adjusting member 704 passes through the first fixing hole and can be slidably set in the first waist-shaped hole to adjust the tightness of the second flexible rope by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0140] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the second fixing seat 702 can be adjusted along the width direction of the first base 717, so that the second fixing seat 702 can tighten or loosen the second flexible rope, thereby adjusting the tightness of the second flexible rope.

[0141] Since the first flexible cable and the second flexible cable are respectively located on the first fixing seat 701 and the second fixing seat 702 on both sides of the first base 717, and the first flexible cable and the second flexible cable are connected to the first slider 714 and the second slider 713 at both ends, when the second fixing seat 702 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the tightness of the second flexible cable is adjusted accordingly, and the tightness of the first flexible cable is also adjusted accordingly under the pulling of the second fixing seat 702 on the second flexible cable.

[0142] Furthermore, in some embodiments, the first fixing base 701 is provided with a second waist-shaped hole extending along the width direction of the first base 717. The first base 717 is provided with a second fixing hole. The sliding door mechanism 7 also includes a second adjusting member 703, which is sequentially passed through the second waist-shaped hole and the second fixing hole and fixed to the external structure. The position of the first fixing base 701 relative to the external structure is adjusted by the position of the second adjusting member 703 in the second waist-shaped hole.

[0143] In this embodiment, a second waist-shaped hole is provided on the first fixing base 701, and the second adjusting member 703 is sequentially passed through the second waist-shaped hole and the second fixing hole to be fixed to the external structure, so that the first fixing base 701 is fixed to the external structure, thereby fixing the sliding door mechanism 7 to the external structure (such as the door 2). At the same time, the second adjusting member 703 can be fine-tuned along the position of the second waist-shaped hole to adjust the position of the first fixing base 701, thereby coordinating the adjustment of the position of the first fixing base 701 relative to the external structure.

[0144] In some embodiments, the second fixing base 702 may also be provided with a second waist-shaped hole extending along the width direction of the first base 717; the second adjustment member 703 is sequentially passed through the second waist-shaped hole and the second fixing hole to be fixed to the external structure, so that the position of the second fixing base 702 relative to the external structure is adjusted by the position of the second adjustment member 703 in the second waist-shaped hole. The functions of the second adjustment member 703, the second waist-shaped hole, and the second fixing hole are similar to those in the above embodiment and are not further described here.

[0145] Furthermore, in some embodiments, a rotatable support bearing is provided in the first limiting groove; a portion of the first flexible cable abuts the support bearing in the first limiting groove. In this embodiment, by abutting a portion of the first flexible cable against the support bearing, the movement and extension direction of the first flexible cable can be adjusted, thereby facilitating the first flexible cable to pass around the end of the first base 717 and connect to the first slider 714 and the second slider 713.

[0146] In some embodiments, a rotatable support bearing may also be provided in the second limiting groove; a portion of the second flexible cable abuts against the support bearing in the second limiting groove to adjust the extension direction of the second flexible cable, making it convenient to pass the second flexible cable around the end of the first base 717 and connect it to the first slider 714 and the second slider 713.

[0147] Specifically, in some embodiments, the support bearing includes a first bearing 705 and a second bearing 716 , which are respectively located at one end of the first guide rail and the second guide rail on the same side and respectively located on both sides of the first base 717 .

[0148] In one embodiment of the present application, as shown in Figures 3 to 5, the traction component includes a traction rod 709, a first rotation shaft fixing seat 707, and a second rotation shaft fixing seat 710. The first rotation shaft fixing seat 707 is connected to the first slider 714, and the second rotation shaft fixing seat 710 is used to connect to the box body 1. One end of the traction rod 709 is rotatably connected to the first rotation shaft fixing seat 707, and the second end of the traction rod 709 is rotatably connected to the second rotation shaft fixing seat 710.

[0149] In this embodiment, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are respectively fixed to the first slider 714 and the box body 1, and the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are connected by a traction rod 709, so that the distance between the first slider 714 and the second rotating shaft fixing seat 710 remains unchanged. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes, so that the first slider 714 is pulled by the transmission connection of the traction rod 709, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, so that the first slider 714 slides on the first base 717, and drives the second slider 713 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0150] Specifically, one end of the traction rod 709 is rotatably connected to the first rotation shaft fixing seat 707 through a pin shaft 708 and a third bearing 715 , and the other end is rotatably connected to the second rotation shaft fixing seat 710 through another pin shaft 708 and another third bearing 715 .

[0151] In another embodiment of the present application, as shown in Figures 1 and 2, a door assembly is provided, comprising: a box door 2, a door panel 21, and a sliding door mechanism 7 as provided in any of the above embodiments. The box door 2 is rotatably connected to the box body 1 and is suitable for opening or closing the storage space of the box body 1. The door panel 21 is slidably arranged on the outside of the box door 2; the sliding door mechanism 7 is arranged on the box door 2, the first slider 714 is used for transmission connection with the box body 1, and the second slider 713 is connected to the door panel 21. During the process of opening or closing the box door 2, the first slider 714 and the second slider 713 move in opposite directions to drive the door panel 21 to move relative to the box door 2.

[0152] Specifically, when the door 2 is rotated to open outside the housing 1 (as indicated by the curved arrow in FIG4 ), the first slider 714 is driven by the housing 1 via the traction component to slide toward the first hinge 4. The first slider 714 drives the second slider 713 to slide away from the first hinge 4 via the flexible cable 706, thereby driving the door panel 21 to slide away from the first hinge 4, thereby preventing the door panel 21 from interfering with external obstacles. Similarly, when the door 2 is rotated to close toward the housing 1, the sliding door mechanism 7 drives the door panel 21 to slide toward the first hinge 4, thereby preventing the door panel 21 from interfering with obstacles after closing.

[0153] According to the door body assembly of the embodiment of the present application, a sliding door mechanism 7 is provided on the box door 2, and the sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21, so that when the box door 2 is rotated to open or close relative to the box body 1, the door panel 21 is driven to slide relative to the width direction of the box door 2, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening process of the box door 2.

[0154] In some embodiments, the sliding door mechanism 7 has the beneficial effects of the above embodiments, and the door body assembly correspondingly has the beneficial effects of the above embodiments. Its specific implementation can refer to the above embodiments, and this application will not repeat them.

[0155] In one embodiment of the present application, as shown in FIG. 3 to FIG. 5 , a first connecting block 712 is provided on the second sliding block 713 , and a slot for hanging the door panel 21 is formed on the first connecting block 712 .

[0156] In this embodiment, a first connecting block 712 is provided on the second slider 713, and a slot is provided on the first connecting block 712. Accordingly, a connecting component (such as a hook, a connector, etc.) adapted to the slot is provided on the door panel 21, so that the door panel 21 can be mounted on the first connecting block 712 and slide along the second slider 713. At the same time, it is also convenient for the user to remove the door panel 21 from the second slider 713 when needed, meeting the user's usage needs in different scenarios.

[0157] In one embodiment of the present application, as shown in Figures 2, 6, and 7, the door assembly further comprises a first driven guide rail mechanism 8. The first driven guide rail mechanism 8 is disposed parallel to the sliding door mechanism 7 on the door 2 and comprises a second base 817 and a third slider 813. A third guide rail is formed on the second base 817, and the third slider 813 is slidably disposed on the third guide rail. The third slider 813 is provided with a second connecting block 812, which has a slot formed on the second connecting block 812 for the door panel 21 to be attached.

[0158] In this embodiment, a first driven guide rail mechanism 8 is provided on the door 2, parallel to the sliding door mechanism 7. The first driven guide rail mechanism 8 includes a second base 817, a third guide rail disposed on the second base 817, and a third slider 813 capable of sliding along the third guide rail. The third slider 813 is connected to the door panel 21 via a second connecting block 812. The third slider 813 is capable of sliding with the door panel 21 as it slides relative to the door 2, providing support and assisting in the sliding of the door panel 21, thereby ensuring smoother sliding of the door panel 21 relative to the door 2. Furthermore, the first driven guide rail mechanism 8 cooperates with the sliding door mechanism 7 to restrict the movement direction of the door panel 21, reducing any shaking of the door panel 21 during sliding and ensuring more stable sliding. Furthermore, the slots in the second connecting block 812 facilitate user installation of the door panel 21 on the driven guide rail mechanism.

[0159] The first driven guide rail mechanism 8 further includes a third fixing seat 801 and a fourth fixing seat 802 . The third fixing seat 801 and the fourth fixing seat 802 are also provided with limiting grooves similar to those of the first fixing seat 701 and the second fixing seat 702 .

[0160] Specifically, a third fixing hole is provided on the third fixing seat 801, and a third waist-shaped hole extending along the width direction of the second base 817 is provided on the second base 817; the third adjusting member 804 passes through the third fixing hole and can be slidably arranged in the third waist-shaped hole to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0161] In some embodiments, a third fixing hole may also be provided on the fourth fixing seat 802; a third waist-shaped hole extending along the width direction of the second base 817 is provided on the second base 817; the third adjusting member 804 passes through the third fixing hole and is slidably provided in the third waist-shaped hole to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0162] Furthermore, the third fixing base 801 is provided with a fourth waist-shaped hole extending along the width direction of the second base 817. The second base 817 is provided with a fourth fixing hole. The fourth adjustment member 803 is sequentially passed through the fourth waist-shaped hole and the fourth fixing hole and fixed to the external structure. The position of the third fixing base 801 relative to the external structure is adjusted by the position of the fourth adjustment member 803 in the fourth waist-shaped hole.

[0163] In some embodiments, the fourth fixing seat 802 may also be provided with a fourth waist-shaped hole extending along the width direction of the third base 902; the fourth adjusting member 803 is fixed in the external structure through the fourth waist-shaped hole and the fourth fixing hole in sequence, so as to adjust the position of the fourth fixing seat 802 relative to the external structure through the position of the fourth adjusting member 803 in the fourth waist-shaped hole.

[0164] In one embodiment of the present application, as shown in Figures 2, 8 and 9, the door body assembly also includes a second driven guide rail mechanism 9, which is arranged off-axis from the sliding door mechanism 7. The second driven guide rail mechanism 9 includes a third base 902 and a fourth slider 903. A fourth guide rail is formed on the third base 902, and the fourth slider 903 is slidably arranged on the fourth guide rail. A plurality of third connecting blocks 905 are provided on the fourth slider 903, and a slot for hanging the door panel 21 is formed on the third connecting block 905.

[0165] In this embodiment, by setting up a second driven guide rail mechanism 9, the fourth slider 903 of the second driven guide rail mechanism 9 can slide with the door panel 21 when the door panel 21 slides relative to the box door 2, thereby supporting and assisting the sliding of the door panel 21, so that the door panel 21 can slide more stably and smoothly relative to the box door 2.

[0166] At the same time, since the second driven guide rail mechanism 9 and the sliding door mechanism 7 are arranged on different axes, the third connecting block 905 can cooperate with the sliding door mechanism 7 to limit the movement direction of the door panel 21, thereby preventing the door panel 21 from deflecting around the sliding direction when sliding, and the sliding process is more stable and reliable.

[0167] In one embodiment of the present application, as shown in FIG8 and FIG9 , a fifth fixing seat 901 and a sixth fixing seat 904 are respectively provided at both ends of the third base 902 of the second driven guide rail mechanism 9 for fixed connection with the box door 2 .

[0168] In one embodiment of the present application, as shown in Figures 2 and 6 to 9, the sliding door mechanism 7, the first driven guide rail mechanism 8 and the second driven guide rail mechanism 9 are arranged along the width direction of the box door 2, the first driven guide rail mechanism 8 and the sliding door mechanism 7 are arranged in parallel, and the second driven guide rail mechanism 9 is arranged off-axis with the sliding door mechanism 7.

[0169] In some embodiments, the width direction of the door 2 is parallel to the plane where the door 2 is located and perpendicular to the rotation axis of the door 2, so that the door panel 21 can move away from or close to the rotation axis of the door 2 (as shown by the double-headed arrow in Figure 4).

[0170] In this embodiment, by arranging the first driven guide rail mechanism 8 parallel to the sliding door mechanism 7, the third slider 813 can slide parallel to the sliding door mechanism 7, effectively assisting the door panel 21 in sliding relative to the door 2 under the drive of the sliding door mechanism 7. Simultaneously, the second connecting block 812 cooperates with the sliding door mechanism 7 to restrict the movement direction of the door panel 21, preventing the door panel 21 from swinging during movement. Furthermore, because the second driven guide rail mechanism 9 is offset from the sliding door mechanism 7, the third connecting block 905 cooperates with the sliding door mechanism 7 to restrict the movement direction of the door panel 21, preventing the door panel 21 from deflecting about the sliding direction during sliding, thereby ensuring a more stable and reliable sliding process.

[0171] In one embodiment of the present application, as shown in Figures 12 to 15, the door body assembly also includes: a first end cover 210 and a second end cover 220, the first end cover 210 is arranged at one end of the box door 2, and a first mounting groove 213 is formed on the first end cover 210, and the sliding door mechanism 7 and the first driven guide rail mechanism 8 are arranged in the first mounting groove 213; the second end cover 220 is arranged at the second end of the box door 2, and a second mounting groove is formed on the second end cover 220, and the second driven guide rail mechanism 9 is arranged in the second mounting groove.

[0172] In this embodiment, by respectively arranging a first end cover 210 and a second end cover 220 at both ends of the box door 2, and forming a first mounting groove 213 on the first end cover 210 to install the sliding door mechanism 7 and the first driven guide rail mechanism 8, and forming a second mounting groove on the second end cover 220 to install the second driven guide rail mechanism 9, the structure of the sliding door mechanism 7, the first driven guide rail mechanism 8, the second driven guide rail mechanism 9 and the box door 2 is more compact and beautiful.

[0173] Optionally, in one embodiment of the present application, as shown in Figure 13, the first driven guide rail mechanism 8 and the second driven guide rail mechanism 9 are both arranged along the width direction of the box door 2, the sliding door mechanism 7 and the first driven guide rail mechanism 8 are arranged at the top of the box door 2, and the second driven guide rail mechanism 9 is arranged at the bottom of the box door 2.

[0174] In this embodiment, the sliding door mechanism 7 and the first driven guide rail mechanism 8 are arranged at the top of the box door 2, and the second driven guide rail mechanism 9 is arranged at the bottom of the box door 2, so that the top of the box door 2 is connected to the door panel 21 through the sliding door mechanism 7 and the first driven guide rail mechanism 8, and the bottom of the box door 2 is connected to the door panel 21 through the second driven guide rail mechanism 9, thereby making the connection between the door panel 21 and the box door 2 more stable and reliable.

[0175] In some embodiments, in another embodiment of the present application, the first driven guide rail mechanism 8 and the second driven guide rail mechanism 9 are both arranged along the width direction of the box door 2, the sliding door mechanism 7 and the first driven guide rail mechanism 8 are arranged at the bottom of the corresponding box door 2, and the second driven guide rail mechanism 9 of the first door body assembly is arranged at the top of the corresponding box door 2.

[0176] In this embodiment, the sliding door mechanism 7 and the first driven guide rail mechanism 8 are arranged at the bottom of the box door 2, and the second driven guide rail mechanism 9 is arranged at the top of the box door 2, so that the top of the box door 2 is connected to the door panel 21 through the sliding door mechanism 7 and the first driven guide rail mechanism 8, and the bottom of the box door 2 is connected to the door panel 21 through the second driven guide rail mechanism 9, thereby making the connection between the door panel 21 and the box door 2 more stable and reliable.

[0177] As shown in Figures 16, 18, 19, 21, and 22, in one embodiment of the present application, the door assembly further comprises: a first main decorative cover 13 and a second main decorative cover 14.

[0201] In some embodiments, the structure of the second hook 2112 is similar to that of the first hook 2111 and is not further described here.

[0202] In one embodiment of the present application, as shown in Figure 2, the door assembly and the cabinet 1 are used to be arranged in an installation space formed between a first cabinet and a second cabinet; during the opening or closing process of the cabinet door 2, the sliding door mechanism 7 is configured to drive the door panel 21 to move a preset distance on the cabinet door 2 so that the door panel 21 avoids the side walls of the first cabinet and the second cabinet.

[0203] In this embodiment, the box body 1 is arranged between the first cabinet body and the second cabinet body. In some embodiments, the material and color of the door panel 21 can be designed to be similar or the same as the material color of the outer wall of the cabinet body. When the box door 2 is closed, the door panel 21 is flush with the outer walls of the first cabinet body and the second cabinet body on both sides, so that the door panel 21 and the outer wall of the cabinet body can maintain visual consistency and the gap is smaller, which is more beautiful.

[0204] When the door 2 swings outward to open, the sliding door mechanism 7 drives the door panel 21 to slide a preset distance away from the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side closest to the first hinge 4, which could prevent the door 2 from opening to a wider angle. When the door 2 swings closed, the sliding door mechanism 7 drives the door panel 21 to slide a preset distance toward the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side away from the first hinge 4, which could prevent the door 2 from fully closing and affect the function of the cabinet 1. When the door 2 is fully closed, the door panel 21 can return to a flush position with the cabinet. By designing a reasonable preset distance, the door panel 21 can avoid interference with the cabinet walls on both sides when sliding relative to the door 2.

[0205] In another embodiment of the present application, the door assembly and the box body 1 are used to be set in a cabinet; during the opening or closing process of the box door 2, the sliding door mechanism 7 is configured to drive the door panel 21 to move a preset distance on the box door 2 so that the door panel 21 avoids the side wall of the cabinet.

[0206] In this embodiment, the box body 1 is set in a single cabinet body. In some embodiments, the material and color of the door panel 21 can be designed to be similar or the same as the material color of the outer wall of the cabinet body. When the box door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet body, so that the door panel 21 and the outer wall of the cabinet body can maintain visual consistency and the gap is smaller, which is more beautiful.

[0207] When the door 2 swings outward to open, the sliding door mechanism 7 drives the door panel 21 to slide a preset distance away from the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side closest to the first hinge 4, which could prevent the door 2 from opening to a wider angle. When the door 2 swings closed, the sliding door mechanism 7 drives the door panel 21 to slide a preset distance toward the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side away from the first hinge 4, which could prevent the door 2 from fully closing and affect the function of the cabinet 1. When the door 2 is fully closed, the door panel 21 can return to a flush position with the cabinet. By designing a reasonable preset distance, the door panel 21 can avoid interference with the cabinet walls on both sides when sliding relative to the door 2.
