[0002] With the increasing demand for the integration of household appliances and home furnishings, the embedded design of household appliances has become a trend.

[0003] However, in order to pursue a better home integration effect, sometimes it is necessary to fixedly connect a door panel to the surface of the cabinet door, and at the same time, the gap between the embedded electrical appliance and the side wall of the cabinet is required to be higher to further improve the home integration effect. This results in that after the electrical appliance is embedded in the cabinet, if the existing hinge technology is adopted, the door body assembly with the door panel will interfere with the side wall of the installation space in the cabinet during the process of opening and closing the door, so that the door body assembly of the electrical appliance cannot be normally opened or closed.

[0101] In today's society, the rapid progress of technology has greatly promoted the transformation of home living styles. Among them, as a design concept integrating aesthetics and practicality, built-in furniture is favored by consumers. By skillfully integrating electrical appliances or storage spaces into the home environment, built-in furniture not only effectively saves space but also significantly improves the overall coordination and aesthetics of the home. Taking a built-in refrigerator as an example, this design enables the refrigerator to be seamlessly embedded in the cabinet, perfectly integrating with the kitchen decoration style, creating a modern and harmonious living environment. However, although built-in refrigerators show significant advantages in enhancing home aesthetics and space utilization, there is still a problem that cannot be ignored in the actual use process: that is, the refrigerator door is prone to interference or collision with the side wall of the cabinet during the opening process, resulting in a poor use experience of the built-in refrigerator.

[0102] Specifically, when the built-in refrigerator (hereinafter referred to as the refrigerator) simultaneously meets the user's different usage requirements for the fully flush and fully built-in refrigerators, after the refrigerator door body (hereinafter referred to as the door) is connected to the cabinet door panel (hereinafter referred to as the panel), the entire door body assembly will thicken. As a result, after the refrigerator is pushed into the accommodation space of the cabinet, relying only on the original single-axis or double-axis structural hinges of the refrigerator, the door body assembly with the cabinet door will interfere with the cabinet during the process of opening and closing the door, resulting in the inability to open and use normally. Therefore, this application proposes a door body assembly that can enable the door to slide relative to the panel, so that during the process of opening the door body assembly, the panel can slide towards the side where the door is opened (i.e., the door-opening side), so that during the process of opening the door, the hinge side still maintains the thickness of the door itself, which is the same as the door-opening scenario without the panel; during the process of closing the door, the panel will move towards the hinge side and return to the state before opening the door; thus realizing the refrigerator embedding installation requirement with or without the panel.

[0103] Among them, if the moving amplitude of the panel relative to the door is too large and the movement is too obvious, it is not only easy to cause interference, but also easy to make users panic, worried that the panel will fall off, and its noise will also bring trouble to users, thereby reducing the user experience.

[0104] Based on this, this application provides a door body assembly for an embedded refrigeration device, combined with Figure 1 , including: a door 2, a sliding mechanism, a panel 21, and a traction mechanism (wherein, the sliding mechanism and the traction mechanism can refer to Figures 2 to 5 ). Among them, the door 2 is rotatably connected to the refrigeration cabinet body, and the refrigeration cabinet body is embedded in the accommodation space formed by the installation body. Here, the installation body generally refers to the cabinet 60. Of course, the installation body can also be a wall corner, or the installation body can also refer to other components, as long as it can form an accommodation space. The following description will take the installation body as the cabinet 60 as an example. The panel 21 is movably installed on the door 2 through the sliding mechanism, and the panel 21 can move along the width direction of the door 2; the traction mechanism is connected to the sliding mechanism, and during the opening or closing process of the door 2, the traction mechanism drives the sliding mechanism to move, so as to drive the panel 21 to move relative to the door 2; the opening angle of the door body assembly is positively correlated with the sliding distance ΔS of the panel 21, and the change value of the sliding distance ΔS of the panel 21 per interval of the preset angle is within the set range.

[0105] According to an embodiment of the present application, since the change value of the sliding distance ΔS of the door panel 21 at every preset angle interval is within a set range, it can be ensured that during the entire door opening process, the sliding distance of the door panel 21 is as uniform as possible or close to uniform. Or, even if the sliding distance cannot reach uniformity, there will be no obvious mutation, so as to ensure that the sliding of the door panel 21 is as hidden as possible and not easily discovered, reduce the noise of the door panel 21, and improve the user experience. And because the movement of the door panel 21 is relatively smooth, interference can be avoided. Moreover, since the change value of the sliding distance ΔS of the door panel 21 at every preset angle interval is within a set range, space can be saved and the minimum required sliding distance can be found.

[0106] According to an embodiment of the present application, the preset angle is 0.5°, and the set range is from 0.193 mm to 0.45 mm. At this time, a small-angle analysis is performed on the opening angle of the door 2 assembly of the box. Since for every 0.5°, the sliding distance ΔS must meet the set conditions, that is, the change value of the sliding distance ΔS is from 0.193 mm to 0.45 mm, the requirements for the sliding mechanism are relatively strict, and this corresponding sliding mechanism can maximize the user experience. Or, the opening angle can also be divided. Before the opening side of the door panel 21 leaves the accommodation space, the preset angle can be 0.5° at this time to ensure that the door panel 21 does not interfere with the side walls of the accommodation space, including the first cabinet board 601 and the second cabinet board 602. After the opening side of the door panel 21 leaves the accommodation space, the preset angle can be larger than the preset angle before leaving. For example, it can be 1°, and more sliding mechanisms that meet the requirements can be obtained.

[0107] In one embodiment, the relationship between the sliding distance ΔS and the door opening degree (i.e., the opening angle) is as follows in the table:

[0108]

[0109] Table 1

[0110] In another embodiment, when other parameters remain unchanged or are slightly adjusted, the relationship between the sliding distance ΔS and the door opening degree (i.e., the opening angle) is as follows in the table:

[0111]

[0112] Table 2

[0113] It should be noted that without limitation, the unit of the relevant distance parameter is millimeter.

[0114] Combined with Table 1, when the opening angle of the door body assembly is 0.5°, the sliding distance is 0.37 mm - 0.47 mm. In addition, when the opening angle of the door body assembly is 90°, the sliding distance is 62.95 mm - 63.04 mm.

[0115] Combined with Table 1 and Figure 32 , the traction mechanism includes a traction rod. The traction rod is hinged to the sliding mechanism through a first pin shaft and is hinged to the box body through a second pin shaft. The distance between the second pin shaft and the end face on the hinge side of the box door 2 is L1. The distance between the hinge axis of the box door 2 and the end face on the hinge side of the box door 2 is L2. The distance between the second pin shaft and the hinge axis of the box door 2 is L3. The distance between the first pin shaft and the hinge axis of the box door 2 in the thickness direction of the box door 2 is L4. The linear distance between the first pin shaft and the second pin shaft is L5. The included angle between the straight line corresponding to L5 and the straight line corresponding to L3 is θ1. The included angle between the straight line corresponding to L5 and the width direction of the accommodation space is θ2. The value of L1 ranges from 30 mm to 40 mm, the value of L2 ranges from 7 mm to 15 mm, the value of L3 ranges from 40 to 55 mm, the value of L4 ranges from 10 mm to 20 mm, the value of L5 ranges from 0.2 mm to 0.4 mm, the value of θ1 ranges from 20° to 105.68°, and the value of θ2 ranges from 15° to 18°. In one embodiment, referring to Table 1, the value of L1 is 36.29 mm, the value of L2 is 10.81 mm, the value of L3 is 47.85 mm, the value of L4 is 16.89, the value of L5 is 0.288 mm, the value of θ1 ranges from 20° to 105.68°, and the value of θ2 is 16.5°. In addition, the above values are mainly combined with product requirements and can float appropriately. For example, taking L2 as an example, within the range of 7 mm - 15 mm, it can meet the installation requirements and ensure the structural strength at the same time.

[0116] Based on the above data, the following relationship can be fitted:

[0117]

[0118] According to the embodiments of the present application, the functions of the sliding mechanism and the traction mechanism are to enable the door panel 21 to move relative to the box door 2. Obviously, the specific structural forms of both are not limited. For example, the sliding mechanism can adopt the double-slider structural form mentioned below, or the link structural form, or the rack and pinion structural form, etc. Correspondingly, the traction mechanism can adopt the structural form of a traction rod, or the direct drive method of a cylinder or a hydraulic cylinder, etc.

[0119] In one embodiment of the present application, as Figures 1 to 5As shown in the figure, the sliding mechanism 7 includes: a first base 717, a first slider 714, a second slider 713, and a flexible cable 706. A first guide rail is formed on one side of the first base 717, and a second guide rail is formed on the other side. The first slider 714 is slidably arranged on the first guide rail, and the traction mechanism is rotatably connected between the box body 1 and the first slider 717. The second slider 713 is slidably arranged on the second guide rail and is used to connect with the door panel 21. Both ends of the flexible cable 706 are respectively connected to the first slider 714 and the second slider 713. When the first slider 714 moves on the first guide rail, the first slider 714 drives the second slider 713 to move in the opposite direction on the second guide rail through the flexible cable 706, so as to drive the door panel 21 to move relative to the width direction of the box door 2.

[0120] It can be understood that the sliding mechanism 7 of this embodiment can be arranged on the box door 2. One of the first slider 714 and the second slider 713 is in transmission connection with the box door 2 or the box body 1, and the other is slidably connected with the door panel 21 arranged outside 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 the box door 2 rotating and opening and closing.

[0121] Specifically, taking the first slider 714 being connected to the box body 1 through the traction mechanism and the second slider 713 being connected to the door panel 21 as an example, the first base 717 of this embodiment can be arranged on the box door 2. Both 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 drive the second slider 713 to move synchronously through the flexible cable 706, and then drive the door panel 21 to slide relative to the box door 2.

[0122] By reasonably setting the extension direction of the flexible cable 706, the movement directions of the first slider 714 and the second slider 713 are opposite during movement, so as to drive the door panel 21 to avoid obstacles.

[0123] For example, during the process of the box door 2 rotating and opening towards the outside of the box body 1, the box door 1 drives the first slider 714 to slide towards the direction close to the first hinge 4 through the traction mechanism. 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) through the flexible cable 706, so as to avoid interference between the door panel 21 and the outside obstacles. During the process of the box door 2 rotating and closing towards one side of the box body 1, the box body 1 drives the first slider 714 to slide away from the first hinge 4, and at the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., close to the first hinge 4) through the flexible cable 706, so as to avoid interference between the door panel 21 and the obstacles after closing.

[0124] It is understandable that the first slider 714 can also be connected to the door panel 21, and correspondingly, the second slider 713 is connected to the box door 2 or the box body 1 through a traction mechanism. The working process is the same as that of the above embodiment and will not be repeated here.

[0125] According to the sliding mechanism 7 of the present application, a first guide rail and a second guide rail are arranged on both sides of a 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 door 2 or the box body 1 through a traction mechanism, and the other is connected to the door panel 21 arranged on the outside of the door 2, so that when the door 2 rotates, the two sliders slide relative to each other to drive the door panel 21 to slide relative to the door 2, so that the door panel 21 can avoid obstacles on both sides during the process of the door 2 turning on and off.

[0126] It should be noted that, in practical 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.

[0127] From the material point of view, 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. The selection of these materials is intended to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0128] In terms of structural design, the first slider 714 and the second slider 713 can adopt various forms of guide rail contact surfaces, such as plane contact, ball contact or sliding bearing contact. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness and maintenance convenience should be comprehensively considered when selecting.

[0129] In addition, in order to enhance the bearing capacity and stability of the slider, 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 anti-deformation ability of the slider, ensuring stable sliding performance when bearing the weight of the door panel 21 and external forces.

[0130] 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 each other along the width direction of the first base 717. While ensuring that the lengths of the first guide rail and the second guide rail can meet the sliding distances 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, making the structure more compact and occupying less space.

[0131] In practical applications, due to factors such as machine tool accuracy, tool wear, and material non-uniformity, there will be certain errors in the machining 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, perpendicularity, etc.). The parallelism between the first guide rail and the second guide rail is evaluated by measuring the relative position deviation between them. This deviation needs to be controlled within a certain tolerance range to ensure the smooth sliding of the slider and the stable operation of the system. This tolerance range is usually determined according to the design requirements, the use environment, and the system accuracy.

[0132] It should be noted that in this embodiment, parallelism and perpendicularity should not be strictly in the geometric sense. At least manufacturing and installation errors should be considered, and errors within plus or minus 10° should be understood as within the scope protected by the patent.

[0133] In an embodiment of the present application, as Figure 3 、 Figure 4 and Figure 5 shown, the flexible cable 706 includes: a first flexible cable and a second flexible cable. The first flexible cable bypasses one 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 bypasses the other end of the first base 717, and its two ends are respectively connected to the other end of the first slider 714 and the second slider 713.

[0134] In this embodiment, by passing the first flexible cable around one end of the first base 717 and connecting it to the first slider 714 and the second slider 713 respectively, when the first slider 714 slides away from this end of the first base 717 under the drive of the door 2 or the box body 1 through the traction mechanism, the first slider 714 drives the second slider 713 to slide towards this end of the first base 717 through the first flexible cable; meanwhile, by passing the second flexible cable around the other end of the first base 717 and connecting it to the first slider 714 and the second slider 713 respectively, when the first slider 714 slides away from this other end of the first base 717 under the drive of the door 2, the first slider 714 drives the second slider 713 to slide towards this other end of the first base 717 through the second flexible cable, so as to achieve that when the first slider 714 slides towards both ends of the first base 717 respectively, it can drive the second slider 713 to slide in the opposite direction to the first slider 714, and further enable the door panel 21 to slide relative to the door 2 as the door 2 rotates when the door 2 is opened and closed, so as to avoid interference with obstacles and affect the opening and closing of the door 2.

[0135] The flexible cable 706 is one of steel wire ropes, steel stranded wires or hemp ropes. It is selected according to the load that the flexible cable 706 needs to bear, the working environment and the usage requirements. For occasions that need to bear large loads and harsh environments, it is recommended to choose steel wire ropes or steel stranded wires; for occasions with smaller loads and mild environments, hemp ropes can be considered. On the premise of meeting the usage requirements, considering the cost differences of different materials, select materials with high cost performance. In addition, steel wire ropes and steel stranded wires may need to be regularly inspected and maintained during use to ensure their performance and safety; while hemp ropes are relatively easy to replace and maintain.

[0136] Specifically, both the second slider 713 and the first slider 714 are provided with connection heads 711 for fixing the flexible cable 706.

[0137] In an embodiment of the present application, as Figure 3 、 Figure 4 and Figure 5 shown, the sliding mechanism 7 further includes: a first fixing seat 701 and a second fixing seat 702. The first fixing seat 701 is connected to one end of the first base 717, forming a first limiting groove. The two ends of the first limiting groove are butted with one ends of the first guide rail and the second guide rail, and a part of the first flexible cable is slidably arranged in the first limiting groove; the second fixing seat 702 is connected to the other end of the first base 717, forming a second limiting groove. The two ends of the second limiting groove are butted with the other ends of the first guide rail and the second guide rail, and a part of the second flexible cable is slidably arranged in the second limiting groove.

[0138] In this embodiment, by providing a first fixing seat 701 and a second fixing seat 702 at both ends of the first base 717 respectively, the first fixing seat 701 and the second fixing seat 702 are respectively formed with a first limiting groove and a second limiting groove for docking with the first guide rail and the second guide rail, so as to limit and guide the positions of the first flexible cable and the second flexible cable respectively, making the sliding of the first flexible cable and the second flexible cable smoother.

[0139] Specifically, the first fixing seat 701 is provided with a first fixing hole, and the first base 717 is provided with a first waist-shaped hole extending along the width direction of the first base 717; the sliding mechanism 7 further includes a first adjusting member 704, the first adjusting member 704 passes through the first fixing hole and is slidably arranged in the first waist-shaped hole, so as to adjust the tightness of the first flexible cable 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 first fixing seat 701 can be adjusted along the width direction of the first base 717, so that the first fixing seat 701 can tension or relax the first flexible cable, thereby adjusting the tightness degree of the first flexible cable.

[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 both ends of the first slider 714 and the second slider 713, when adjusting the movement of the first fixing seat 701 relative to the first base 717 through the first waist-shaped hole, the tightness degree of the first flexible cable is correspondingly adjusted, and the second flexible cable is also correspondingly adjusted in tightness under the pulling of the first fixing seat 701 on the first flexible cable.

[0142] It can be understood that the first fixing hole can also be provided on the second fixing seat 702; the first base 717 is provided with a first waist-shaped hole extending along the width direction of the first base 717; the sliding mechanism 7 further includes a first adjusting member 704, the first adjusting member 704 passes through the first fixing hole and is slidably arranged in the first waist-shaped hole, so as to adjust the tightness of the second flexible cable by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0143] 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 tension or relax the second flexible cable, thereby adjusting the tightness degree of the second flexible cable.

[0144] 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 both ends of the first slider 714 and the second slider 713, when adjusting the movement of the second fixing seat 702 relative to the first base 717 through the first waist-shaped hole, the second flexible cable correspondingly adjusts its tightness, and the first flexible cable also correspondingly adjusts its tightness under the pulling of the second flexible cable by the second fixing seat 702.

[0145] Further, in some embodiments, the first fixing seat 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 mechanism 7 further includes a second adjusting member 703, and the second adjusting member 703 passes through the second waist-shaped hole and the second fixing hole in sequence and is fixed in the external structure, so as to adjust the position of the first fixing seat 701 relative to the external structure through the position of the second adjusting member 703 in the second waist-shaped hole.

[0146] In this embodiment, by providing the second waist-shaped hole on the first fixing seat 701 and fixing the second adjusting member 703 through the second waist-shaped hole and the second fixing hole in sequence in the external structure, the first fixing seat 701 is fixed in the external structure, so as to fix the sliding mechanism 7 on the external structure (such as the door 2). At the same time, the second adjusting member 703 can be finely adjusted in the position along the second waist-shaped hole, so as to adjust the position of the first fixing seat 701, thereby being able to cooperate to adjust the position of the first fixing seat 701 relative to the external structure.

[0147] It can be understood that the second fixing seat 702 can also be provided with a second waist-shaped hole extending along the width direction of the first base 717; the second adjusting member 703 passes through the second waist-shaped hole and the second fixing hole in sequence and is fixed in the external structure, so as to adjust the position of the second fixing seat 702 relative to the external structure through the position of the second adjusting member 703 in the second waist-shaped hole. The functions of the second adjusting member 703, the second waist-shaped hole and the second fixing hole are similar to those in the above embodiments, and will not be described in detail here.

[0148] Further, in some embodiments, a rotatable support bearing is provided in the first limiting groove; a part of the first flexible cable abuts against the support bearing in the first limiting groove. In this embodiment, by abutting a part of the first flexible cable against the support bearing, the movement and extension direction of the first flexible cable are adjusted, which is convenient for bypassing the end of the first base 717 to connect the first slider 714 and the second slider 713.

[0149] It is understandable that a rotatable support bearing can also be provided in the second limit groove; a part of the second flexible cable abuts against the support bearing in the second limit groove, so as to adjust the extension direction of the second flexible cable, and it is convenient to bypass 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.

[0150] Specifically, in some embodiments, the support bearing includes a first bearing 705 and a second bearing 716. The first bearing 705 and the second bearing 716 are respectively located at one end on the same side of the first guide rail and the second guide rail, and are respectively located on both sides of the first base 717.

[0151] In an embodiment of the present application, as Figures 3 to 5 shown, the traction mechanism includes a traction rod 709, a first pin shaft fixing seat 707 and a second pin shaft fixing seat 710. The first pin shaft fixing seat 707 is connected to the first slider 714, the second pin shaft fixing seat 710 is used to be connected to the box body 1, one end of the traction rod 709 is rotatably connected to the first pin shaft fixing seat 707, and the other end of the traction rod 709 is rotatably connected to the second pin shaft fixing seat 710.

[0152] In this embodiment, by respectively fixing the first pin shaft fixing seat 707 and the second pin shaft fixing seat 710 on the first slider 714 and the box body 1, and connecting them through the traction rod 709 between the first pin shaft fixing seat 707 and the second pin shaft fixing seat 710, the distance between the first slider 714 and the second pin shaft fixing seat 710 is always kept 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. Thus, the first slider 714 is tractioned through the transmission connection of the traction rod 709, the first pin shaft fixing seat 707 and the second pin 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.

[0153] Specifically, one end of the traction rod 709 and the first pin shaft fixing seat 707 are rotatably connected through a pin shaft 708 and a third bearing 715, and the other end and the second pin shaft fixing seat 710 are rotatably connected through another pin shaft 708 and another third bearing 715. Among them, the pin shaft 708 between the traction rod 709 and the first pin shaft fixing seat 707 is the first pin shaft, and the pin shaft between the traction rod 709 and the second pin shaft fixing seat 710 is the second pin shaft.

[0154] In an embodiment of another aspect of the present application, as Figure 1 and Figure 2As shown in the figure, a door assembly is provided, including: a box door 2, a door panel 21, and a sliding mechanism 7 provided in any of the above embodiments. The box door 2 is rotatably connected to the box body 1 and is adapted to open or close the storage space of the box body 1. The door panel 21 is slidably disposed on the outer side of the box door 2; the sliding mechanism 7 is disposed on the box door 2, and a first slider 714 is used for driving connection with the box body 1, and a second slider 713 is connected to the door panel 21. During the opening or closing process of 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.

[0155] Specifically, during the process of the box door 2 rotating outwardly relative to the box body 1 to open (as shown by the curved arrow in Figure 4 ), the first slider 714 slides in the direction close to the first hinge 4 under the drive of the box body 1 through a traction mechanism, and the first slider 714 drives the second slider 713 to slide in the direction away from the first hinge 4 through a flexible cable 706, thereby driving the door panel 21 to slide in the direction away from the first hinge 4, and further avoiding interference between the door panel 21 and the external obstacles. Similarly, during the process of the box door 2 rotating toward one side of the box body 1 to close, the sliding mechanism 7 drives the door panel 21 to slide in the direction close to the first hinge 4, thereby avoiding interference between the door panel 21 and the obstacles after closing.

[0156] According to the door assembly of the embodiment of the present application, the sliding mechanism 7 is disposed on the box door 2, and the sliding mechanism 7 is respectively connected to the box door 2 and the door panel 21, so as to drive the door panel 21 to slide in the width direction relative to the box door 2 during the process of the box door 2 rotating open or close relative to the box body 1, 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.

[0157] It can be understood that if the sliding mechanism 7 has the beneficial effects of the above embodiments, the door assembly correspondingly has the beneficial effects of the above embodiments, and its specific implementation manners can refer to the above embodiments, and the present application will not be elaborated herein.

[0158] In an embodiment of the present application, as Figures 3 to 5 shown, a first connection block 712 is provided on the second slider 713, and a slot for hanging the door panel 21 is formed on the first connection block 712.

[0159] In this embodiment, by providing the first connection block 712 on the second slider 713 and providing a slot on the first connection block 712, correspondingly, a connection component (such as a hook, a plug-in component, etc.) adapted to the slot is provided on the door panel 21, so as to install the door panel 21 on the first connection block 712, so that the door panel 21 can slide with 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 usage requirements of the user in different scenarios.

[0160] In an embodiment of the present application, Figure 2 , Figure 6 and Figure 7 As shown, the door body assembly further includes: a first driven guide rail mechanism 8. The first driven guide rail mechanism 8 is arranged in parallel with the sliding mechanism 7 on the box door 2 and includes a second base 817 and a third slider 813. A third guide rail is formed on the second base 817, the third slider 813 is slidably arranged on the third guide rail, a second connecting block 812 is provided on the third slider 813, and a slot for hanging and connecting the door panel 21 is formed on the second connecting block 812.

[0161] In this embodiment, by arranging the first driven guide rail mechanism 8 parallel to the sliding mechanism 7 on the box door 2, the first driven guide rail mechanism 8 has a second base 817, a third guide rail is provided on the second base 817, and a third slider 813 that can slide along the third guide rail. The third slider 813 is connected to the door panel 21 through the second connecting block 812. The third slider 813 can slide along with the door panel 21 when the door panel 21 slides relative to the box door 2, playing a supporting and assisting role in the sliding of the door panel 21, making the sliding of the door panel 21 relative to the box door 2 smoother. At the same time, the first driven guide rail mechanism 8 can cooperate with the sliding mechanism 7 to limit the movement direction of the door panel 21, reduce the shaking of the door panel 21 during the sliding process, and make the sliding more stable. In addition, the slot on the second connecting block 812 can facilitate the user to install the door panel 21 on the driven guide rail mechanism.

[0162] Furthermore, 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.

[0163] 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; a third adjusting member 804 passes through the third fixing hole and is slidably arranged in the third waist-shaped hole to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0164] It can be understood that a third fixing hole can 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; a third adjusting member 804 passes through the third fixing hole and is slidably arranged in the third waist-shaped hole to adjust the position of the third adjusting member 804 in the third waist-shaped hole

[0165] Further, a fourth waist-shaped hole extending in the width direction of the second base 817 is provided on the third fixing base 801. A fourth fixing hole is provided on the second base 817. The fourth adjusting member 803 passes through the fourth waist-shaped hole and the fourth fixing hole in sequence and is fixed to the external structure, so as to adjust the position of the third fixing base 801 relative to the external structure by the position of the fourth adjusting member 803 in the fourth waist-shaped hole.

[0166] It can be understood that a fourth waist-shaped hole extending in the width direction of the third base 902 can also be provided on the fourth fixing base 802; the fourth adjusting member 803 passes through the fourth waist-shaped hole and the fourth fixing hole in sequence and is fixed to the external structure, so as to adjust the position of the fourth fixing base 802 relative to the external structure by the position of the fourth adjusting member 803 in the fourth waist-shaped hole.

[0167] In an embodiment of the present application, as Figure 2 、 Figure 8 and Figure 9 shown, the door body assembly further includes a second driven guide rail mechanism 9. The second driven guide rail mechanism 9 is arranged coaxially with the sliding 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. 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. Slots for hanging the door panel 21 are formed on the third connecting blocks 905.

[0168] In this embodiment, by providing the second driven guide rail mechanism 9, the fourth slider 903 of the second driven guide rail mechanism 9 can slide along with the door panel 21 when the door panel 21 slides relative to the box door 2, playing a supporting and auxiliary role in the sliding of the door panel 21, making the sliding of the door panel 21 relative to the box door 2 more stable and smooth.

[0169] At the same time, since the second driven guide rail mechanism 9 is arranged coaxially with the sliding mechanism 7, the third connecting block 905 can cooperate with the sliding mechanism 7 to limit the movement direction of the door panel 21, avoiding the deflection of the door panel 21 around the sliding direction during sliding, and the sliding process is more stable and reliable.

[0170] In an embodiment of the present application, as Figure 8 and Figure 9 shown, fifth fixing seats 901 and sixth fixing seats 904 are respectively arranged at both ends of the third base 902 of the second driven guide rail mechanism 9 for fixedly connecting with the box door 2.

[0171] Further, in an embodiment of the present application, as Figure 2 、 Figures 6 to 9As shown, the sliding 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 door 2. The first driven guide rail mechanism 8 is arranged parallel to the sliding mechanism 7, and the second driven guide rail mechanism 9 is arranged coaxially with the sliding mechanism 7.

[0172] It can be understood that the width direction of the door 2 is parallel to the plane where the door 2 is located and perpendicular to the rotating shaft of the door 2, so that the door panel 21 can move away from or close to the rotating shaft of the door 2 (as Figure 4 shown by the double-headed arrow in the figure).

[0173] In this embodiment, by arranging the first driven guide rail mechanism 8 parallel to the sliding mechanism 7, the third slider 813 can slide parallel to the sliding mechanism 7, better assisting the door panel 21 to slide relative to the door 2 under the drive of the sliding mechanism 7. At the same time, the second connecting block 812 can cooperate with the sliding mechanism 7 to limit the movement direction of the door panel 21, preventing the door panel 21 from swinging during the movement. At the same time, since the second driven guide rail mechanism 9 is arranged coaxially with the sliding mechanism 7, the third connecting block 905 can cooperate with the sliding mechanism 7 to limit the movement direction of the door panel 21, preventing the door panel 21 from deflecting around the sliding direction during sliding, and the sliding process is more stable and reliable.

[0174] In an embodiment of the present application, as Figures 12 to 15 shown, the door body assembly further includes: a first end cover 210 and a second end cover 220. The first end cover 210 is arranged at one end of the door 2, and a first installation groove 213 is formed on the first end cover 210. The sliding mechanism 7 and the first driven guide rail mechanism 8 are arranged in the first installation groove 213; the second end cover 220 is arranged at the other end of the door 2, and a second installation groove is formed on the second end cover 220. The second driven guide rail mechanism 9 is arranged in the second installation groove.

[0175] In this embodiment, by respectively arranging the first end cover 210 and the second end cover 220 at both ends of the door 2, forming a first installation groove 213 on the first end cover 210 to install the sliding mechanism 7 and the first driven guide rail mechanism 8, and forming a second installation groove on the second end cover 220 to install the second driven guide rail mechanism 9, the structures of the sliding mechanism 7, the first driven guide rail mechanism 8, the second driven guide rail mechanism 9 and the door 2 are made more compact and beautiful.

[0204] It can be understood that the structure of the second hook 2112 is similar to that of the first hook 2111 and will not be elaborated here.

[0205] In an embodiment of the present application, as Figure 2 shown, the door body assembly and the cabinet 1 are used to be arranged in the installation space formed between the first cabinet and the second cabinet; during the opening or closing process of the cabinet door 2, the sliding 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.

[0206] In this embodiment, the cabinet 1 is arranged between the first cabinet and the second cabinet. It can be understood that the material and color of the door panel 21 can be designed to be similar to or the same as the material color of the outer wall of the cabinet. When the cabinet door 2 is closed, the door panel 21 is flush with the outer walls of the first cabinet and the second cabinet on both sides, so that the door panel 21 and the outer wall of the cabinet can maintain visual consistency and have a small gap, which is more beautiful.

[0207] When the cabinet door 2 rotates outward to open, the sliding mechanism 7 drives the door panel 21 to slide a preset distance away from the first hinge 4, so as to prevent the door panel 21 from interfering with the cabinet wall on the side close to the first hinge 4, resulting in the cabinet door 2 being unable to open to a larger angle. When the cabinet door 2 rotates to close, the sliding mechanism 7 drives the door panel 21 to slide a preset distance towards the first hinge 4, so as to prevent the door panel 21 from interfering with the cabinet wall on the side away from the first hinge 4, resulting in the cabinet door 2 being unable to close completely and affecting the function of the cabinet body 1. And when the cabinet door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet body. By designing a reasonable preset distance, it is possible to prevent the door panel 21 from interfering with the cabinet walls on both sides when sliding relative to the cabinet door 2.

[0208] In another embodiment of the present application, the door body assembly and the cabinet body 1 are used to be arranged in a cabinet; during the opening or closing process of the cabinet door 2, the sliding 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 wall of the cabinet.

[0209] In this embodiment, the cabinet body 1 is arranged in a single cabinet. It can be understood that the material and color of the door panel 21 can be designed to be similar to or the same as the material color of the outer wall of the cabinet. When the cabinet door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet, so that the door panel 21 and the outer wall of the cabinet can maintain visual consistency and have a small gap, which is more beautiful.

[0210] When the cabinet door 2 rotates outward to open, the sliding mechanism 7 drives the door panel 21 to slide a preset distance away from the first hinge 4, so as to prevent the door panel 21 from interfering with the cabinet wall on the side close to the first hinge 4, resulting in the cabinet door 2 being unable to open to a larger angle. When the cabinet door 2 rotates to close, the sliding mechanism 7 drives the door panel 21 to slide a preset distance towards the first hinge 4, so as to prevent the door panel 21 from interfering with the cabinet wall on the side away from the first hinge 4, resulting in the cabinet door 2 being unable to close completely and affecting the function of the cabinet body 1. And when the cabinet door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet body. By designing a reasonable preset distance, it is possible to prevent the door panel 21 from interfering with the cabinet walls on both sides when sliding relative to the cabinet door 2.
