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

[0102] The following is combined with Figures 1 to 36 to describe the door body assembly and the refrigeration device of the embedded refrigeration device of this application.

[0103] In one embodiment of this application, as Figures 1 to 2 shown, this application provides a door body assembly of an embedded refrigeration device. Please refer to Figure 1, including a cabinet door 2 and a door panel 21. The cabinet door 2 is rotatably connected to the refrigeration cabinet body 1 to open or close the storage space inside the refrigeration cabinet body 1. The refrigeration cabinet body 1 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 will describe the installation body as the cabinet 60 as an example. The door panel 21 is movably installed on the cabinet door 2, and the door panel 21 can move along the width direction of the cabinet door 2; the door panel 21 is adapted to move relative to the cabinet door 2 towards the opening side of the cabinet door 2 during the opening process of the cabinet door 2.

[0104] According to an embodiment of the present application, the door panel 21 is installed on the cabinet door 2 through a sliding mechanism (refer to Figure 4 , the sliding door mechanism 7 includes a sliding mechanism and a traction mechanism, where the sliding mechanism and the traction mechanism are not separately marked, and the structure of the traction mechanism can be referred to Figure 5 for the traction rod 709, and the sliding mechanism can be referred to Figure 5 for the first base 717, the first slider 714 and the second slider 713), and the door panel 21 can move along the width direction of the cabinet door 2, and the moving distance is d. Specifically, the traction mechanism is connected to the sliding mechanism, and during the opening or closing process of the cabinet door 2, the traction mechanism drives the sliding mechanism to move, so as to drive the door panel 21 to move relative to the cabinet door 2. According to an embodiment of the present application, the maximum opening angle of the door body assembly is 90° - 135°, and the moving distance d of the door panel is between 14.15 mm and 109.108 mm. Among them, the maximum opening angle and the minimum value of the moving distance d are positively correlated, that is, when the maximum opening angle is larger, the minimum value of the corresponding moving distance d at this time is larger. For example, when the maximum opening angle is 96°, the minimum value of the moving distance d at this time is 15.233 mm to 66.616 mm; when the maximum opening angle is 135°, the minimum value of the moving distance d required at this time is 67.883 mm to 109.108 mm.

[0105] According to an embodiment of the present application, when the maximum opening angle is 90° - 135° and the minimum value of the corresponding moving distance d is between 14.15 mm and 109.108 mm, it can further ensure that the door panel does not interfere, and based on the minimum value of the moving distance, it can be used as a design reference standard for the sliding mechanism to ensure that the obtained door body assembly can improve the user experience.

[0106] According to an embodiment of the present application, in order to meet the use requirements of the refrigeration equipment and keep the style unified between the refrigeration equipment and the installation body, combined with Figure 2, the thickness D1 of the door panel is generally between 12 mm and 25 mm, and the thickness D2 of the cabinet door is generally between 20 mm and 60 mm. Of course, the numerical ranges here do not limit the embodiments of the present application.

[0107] According to the embodiments of the present application, in order to further ensure the use safety of the door body assembly, when the door panel 21 is at the maximum opening angle, combined Figure 2 , the safety gap A between the interference position and the panel of the mounting body is 1 mm - 5 mm. The interference position refers to the position on the hinge side of the door panel 21 where interference is most likely to occur, corresponding to the outer corner on the hinge side of the door panel 21. Of course, the gap between the interference position and the panel of the mounting body can also be infinitely close to zero, and at this time, it just ensures that there is no interference between the interference position and the panel of the mounting body. The gap between the interference position and the panel of the mounting body is not limited by the examples here. In addition, for the convenience of assembling the door body assembly, the assembly gap B between the door panel and the cabinet door can be 1 mm - 10 mm, and the gap C from the cabinet door to the refrigeration cabinet body can be 3 mm - 15 mm. Similarly, the examples here do not limit the door body assembly.

[0108] Combined with the following table, the safety gap A can be selected as 1 mm, 3 mm, 4 mm, the assembly gap B can be selected as 1 mm, 2 mm, 5.6 mm, 10 mm, the assembly gap C can be selected as 3 mm, 4 mm, 8 mm, 10.5 mm, 10 mm, the door panel thickness can be selected as 12 mm, 18 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, the cabinet door thickness can be selected as 20 mm, 23 mm, 33 mm, 38 mm, 40 mm, 45 mm, 47 mm, 52 mm, 60 mm, and the distance from the bottom of the cabinet door 2 to the refrigeration cabinet body 1 at the maximum opening angle can be 35.85 mm, 20 mm, 30 mm. On this basis, corresponding to different maximum opening angles, different minimum moving distances can be obtained. Please refer to the following table.

[0109]

[0110] Table 1

[0111]

[0112] Table 2

[0113]

[0114] Table 3

[0115] The data with a gray background in Table 2 above are the preferred data, that is, corresponding to Table 2, the safety clearance A is 3 mm, the assembly clearance B is 2 mm, the clearance C is 8 mm, the door panel thickness D1 is 18 mm, the box door thickness D2 is 23 mm to 60 mm, the dimension E corresponds to 30 mm, and the data corresponding to the maximum opening angle is 96° to 135°. Correspondingly, the value of L2 ranges from 24.133 mm to 67.883 mm.

[0116] According to an embodiment of the present application, in combination with Figure 2 , when the opening angle of the box door 2 is ninety degrees, the moving distance is d1, and d1 is not less than the sum of the distance t and the distance l3, where t is the distance between the hinge axis of the box door 2 and the opening of the accommodation space, and l3 is the vertical distance from the hinge axis 101 of the box door 2 to the end face of the hinge side of the door panel 21. In the above case, that is, once the opening angle of the box door 2 reaches ninety degrees, the door panel 21 is completely outside the accommodation space. Thus, it is obvious that interference between the door panel 21 and the inner wall of the accommodation space can be avoided. And at this time, it is equivalent to that the end face of the hinge side of the door panel 21 extends beyond the installation body, and further interference between the end face of the hinge side of the door panel 21 and the outer surface of the installation body can be avoided.

[0117] On this basis, if the maximum opening angle is greater than ninety degrees, in order to ensure that the door panel 21 does not interfere during the opening process of the door body assembly, it is further necessary to ensure that d - t - l3 is not less than the distance that the interference position of the door panel 21 moves along the depth direction of the accommodation space towards the cabinet body after ninety degrees, where the depth direction of the accommodation space is perpendicular to Figure 1 the width direction of the box door marked by the arrow when the box door is closed. Please refer to Figure 2 , the door panel 21 has an interference position at point c0, and the interference position is located at the outer corner of the hinge side of the door panel 21. The "outer" here is relative to the refrigeration cabinet body 1, and the side facing away from the refrigeration cabinet body 1 is the "outer" side, and vice versa, the side facing the refrigeration cabinet body 1 is the "inner" side. Since Figure 2 is a top view, the interference position c0 is a point when viewed from Figure 2 . It can be understood that for the door body assembly, the interference position is a vertical line. Among them, if the outer corner of the hinge side of the door panel 21 is arc-shaped, the interference position at this time is the point on the arc segment that is farthest from the hinge axis 101 of the box door 2.

[0118] According to the embodiment of the present application, the maximum opening angle Δθ is between ninety degrees and one hundred and thirty-five degrees, that is, 90° ≤ Δθ ≤ 135°. At this opening angle, all the user's taking and placing requirements can be met, and the opened door panel 21 will not occupy too much usable space. Of course, the maximum opening angle Δθ can also be other values.

[0119] According to an embodiment of the present application, after the interference position leaves the accommodation space and corresponds to the installation body, the distance between the interference position and the panel of the installation body is A, and A > 0. That is to say, when the interference position leaves the area corresponding to the accommodation space and moves towards the second cabinet panel 602 on the right side of the cabinet 60, in order to prevent interference, the distance A between the interference position and the outer surface of the second cabinet panel 602 is always greater than zero.

[0120] According to another embodiment of the present application, in combination with Figure 2 , the moving distance d of the door panel 21 and the maximum opening angle Δθ of the door body assembly satisfy:

[0121] d = (A1 + B + C + D1 + D2 - E) / sin(180 - Δθ).

[0122] Among them, A1 is the safety gap between the corner corresponding to the interference position of the door panel 21 and the panel of the installation body at the maximum opening angle, B is the assembly gap between the door panel 21 and the cabinet door 2, C is the gap between the cabinet door 2 and the refrigeration cabinet body 1, D1 is the thickness of the door panel 21, D2 is the thickness of the cabinet door 2, and E is the distance from the innermost corner of the cabinet door 2 to the refrigeration cabinet body 1 at the maximum opening angle. A1, B, C, D1, and D2 are known, and thus the relationship between d and Δθ can be obtained. Among them, E can be directly a given design quantity, or E is L3 / sin(180 - Δθ), where L3 is the distance between the axis of the slide rail hinge and the outer surface of the cabinet door. Note that l3 and L3 are different, and l3 and L3 are marked perpendicular to each other in the figure.

[0123] Figure 3 and Figure 4 In, a sliding mechanism 4 is connected between the door panel 21 and the cabinet door 2, and the sliding mechanism 4 is connected to a traction mechanism, and the door panel 21 is driven to move relative to the cabinet door 2 under the drive of the traction mechanism. The sliding mechanism 4 includes a slide rail and a slider moving along the slide rail (the structure of the sliding mechanism 4 will be illustrated later).

[0124] Among them, when the traction mechanism is a link mechanism, if the transmission ratio of the link mechanism is 1:1, the moving distance L2 of the hinge axis connected by the link mechanism and the traction mechanism is the moving distance d of the door panel 21 relative to the cabinet door 2.

[0125] Figure 2 In, when the door body assembly is in the closed position, the farthest distance from the end face of the refrigeration cabinet body 1 corresponding to the hinge side to the hinge axis is L, that is, the farthest distance from the end face of the hinge side of the door panel 21 to the hinge axis is L; the distance from the end face of the refrigeration cabinet body 1 corresponding to the hinge side to the hinge axis at the maximum opening angle is L1, where L1 is a design given quantity, and the displacement of the hinge axis when the refrigerator door 2 is opened from the closed position to the maximum opening angle is L2 (the maximum sliding amount).

[0126] L2 = d = (A1 + B + C + D1 + D2 - E) / sin(180 - Δθ), and then when other parameters are determined, the relationship between the maximum opening angle Δθ and L2 can be obtained.

[0127] According to the embodiments of the present application, the difference between A1 and A can also be ignored, and A1 in the formula can be replaced with A, where A is the safety gap between the interference position of the door panel 21 and the panel of the installation body at the maximum opening angle. Obviously, A1 = A + D1×cos(180 - Δθ). As long as A satisfies a certain range, the L2 calculated based on L2 = d = (A + B + C + D1 + D2 - E) / sin(180 - Δθ) can meet the requirements. For example, if A takes a value between 1 and 5 millimeters, the calculated moving distance L2 can meet the requirement of non-interference.

[0128] Similarly, the above formula for d and the maximum opening angle Δθ of the door body assembly is not restrictive. For example, the above calculation formula can also have a correction coefficient or correction parameter. In addition, the above calculation formula is for the case where the hinge axis 101 of the box door 2 is determined. If the box door 2 is installed with a double-axis hinge or a movable hinge, the hinge axis 101 will change as the box door 2 opens, and the moving distance of the hinge axis 101 needs to be calculated in the formula.

[0129] According to the embodiments of the present application, the sliding door mechanism 7 includes a sliding mechanism and a traction mechanism.

[0130] According to an embodiment of the present application, please refer to Figures 4 to 5 that the sliding mechanism 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 disposed 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 disposed on the second guide rail and is used to connect with the door panel 21. Both ends of the flexible cable 706 are connected to the first slider 714 and the second slider 713 respectively. 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.

[0131] It is understandable that the sliding mechanism 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.

[0132] 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.

[0133] By reasonably setting the extension direction of the flexible cable 706, the first slider 714 and the second slider 713 move in opposite directions during movement, so as to drive the door panel 21 to avoid obstacles.

[0134] 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 (that is, 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. At the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (that is, 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.

[0135] It is understandable that 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 the traction mechanism, and its working process is the same as that of the above embodiment, and will not be repeated here.

[0136] According to the sliding mechanism 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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 in parallel along 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.

[0142] 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 design requirements, usage environment, and system accuracy.

[0143] 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 to be within the scope protected by the patent.

[0144] In an embodiment of the present application, as 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 ends 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 ends of the first slider 714 and the second slider 713.

[0145] In this embodiment, by connecting the first flexible cable to the first slider 714 and the second slider 713 respectively after bypassing one end of the first base 717, 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; at the same time, by connecting the second flexible cable to the first slider 714 and the second slider 713 respectively after bypassing the other end of the first base 717, when the first slider 714 slides away from the 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 the other end of the first base 717 through the second flexible cable, so 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.

[0146] The flexible cable 706 is one of steel wire ropes, steel stranded wires or hemp ropes, and is selected according to the load to be borne by the flexible cable 706, 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, the use of hemp ropes can be considered. On the premise of meeting the usage requirements, considering the cost differences of different materials, choose 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.

[0147] Specifically, both the second slider 713 and the first slider 714 are provided with connection heads 711 for fixing the flexible cable 706.

[0148] In an embodiment of the present application, as Figure 5 shown, the sliding mechanism 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. Both ends of the first limiting groove are docked 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, which is connected to the other end of the first base 717, forms a second limiting groove. Both ends of the second limiting groove are docked 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.

[0149] In this embodiment, by respectively arranging the first fixing seat 701 and the second fixing seat 702 at both ends of the first base 717, and the first fixing seat 701 and the second fixing seat 702 respectively form a first limiting groove and a second limiting groove that are docked with the first guide rail and the second guide rail, the positions of the first flexible cable and the second flexible cable are respectively limited and guided, making the sliding of the first flexible cable and the second flexible cable smoother.

[0150] 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 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 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.

[0151] 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 of the first flexible cable.

[0152] 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 first flexible cable correspondingly adjusts its tightness, and the second flexible cable also correspondingly adjusts its tightness under the pulling of the first flexible cable by the first fixing seat 701.

[0153] It can be understood that a first fixing hole can also be provided 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 mechanism 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.

[0154] 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 of the second flexible cable.

[0155] 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.

[0156] Furthermore, in some embodiments, a second waist-shaped hole extending along the width direction of the first base 717 is provided on the first fixing seat 701. A second fixing hole is provided on the first base 717. The sliding mechanism further includes a second adjusting member 703, the second adjusting member 703 sequentially passes through the second waist-shaped hole and the second fixing hole and is fixed in the external structure, so as to adjust the position of the first fixing seat 701 relative to the external structure by the position of the second adjusting member 703 in the second waist-shaped hole.

[0157] In this embodiment, by providing a second waist-shaped hole on the first fixing base 701 and passing the second adjusting member 703 through the second waist-shaped hole and the second fixing hole in sequence to be fixed in the external structure, the first fixing base 701 is fixed in the external structure, so as to fix the sliding mechanism on the external structure (such as the box 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 base 701, and thus the position of the first fixing base 701 relative to the external structure can be cooperatively adjusted.

[0158] It can be understood that a second waist-shaped hole extending along the width direction of the first base 717 can also be provided on the second fixing base 702; the second adjusting member 703 passes through the second waist-shaped hole and the second fixing hole in sequence to be fixed in the external structure, so as to adjust the position of the second fixing base 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 embodiment and will not be elaborated here.

[0159] 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 facilitates bypassing the end of the first base 717 of the first flexible cable to be connected to the first slider 714 and the second slider 713.

[0160] It can be understood that a rotatable support bearing can also be provided in the second limiting groove; a part of the second flexible cable abuts against the support bearing in the second limiting groove, so as to adjust the extension direction of the second flexible cable, which facilitates bypassing the end of the first base 717 of the second flexible cable to be connected to the first slider 714 and the second slider 713.

[0161] 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.

[0162] In an embodiment of the present application, as Figure 5 shown, the traction mechanism includes a traction rod 709, a first rotating shaft fixing base 707 and a second rotating shaft fixing base 710. The first rotating shaft fixing base 707 is connected to the first slider 714, the second rotating shaft fixing base 710 is used for connecting to the box body 1, one end of the traction rod 709 is rotatably connected to the first rotating shaft fixing base 707, and the other end of the traction rod 709 is rotatably connected to the second rotating shaft fixing base 710.

[0163] In this embodiment, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are respectively fixed on the first slider 714 and the box body 1, and are connected by a traction rod 709 between the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, so that the distance between the first slider 714 and the second rotating shaft fixing seat 710 is always kept unchanged. When the door 2 rotates relative to the box body 1, the angle between the box body 1 and the door 2 changes. Thus, the first slider 714 is pulled through 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 door 2.

[0164] Specifically, one end of the traction rod 709 and the first rotating shaft fixing seat 707 are rotatably connected through a pin shaft 708 and a third bearing 715, and the other end and the second rotating shaft fixing seat 710 are rotatably connected through another pin shaft 708 and another third bearing 715.

[0165] In an embodiment of another aspect of the present application, as Figure 3 and Figure 4 shown, a door body assembly is provided, including: a door 2, a door panel 21 and a sliding mechanism provided in any of the above embodiments. The 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 arranged outside the door 2; the sliding mechanism is arranged on the door 2, the first slider 714 is used for driving connection with the box body 1, and the second slider 713 is connected to the door panel 21. During the opening or closing process of the 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 door 2.

[0166] Specifically, during the process of the door 2 rotating outward to open relative to the box body 1, 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, so as to drive the door panel 21 to slide in the direction away from the first hinge 4, thereby avoiding interference between the door panel 21 and external obstacles. Similarly, during the process of the door 2 rotating to close on one side of the box body 1, the sliding mechanism 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 obstacles after closing.

[0167] According to the door body assembly of the embodiment of the present application, a sliding mechanism is arranged on the door 2, and the sliding mechanism is respectively connected to the door 2 and the door panel 21, so as to drive the door panel 21 to slide in the width direction relative to the door 2 during the process of the door 2 rotating to 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 door 2.

[0168] It is understandable that the sliding mechanism has the beneficial effects of the above-mentioned embodiments, so the door body assembly correspondingly has the beneficial effects of the above-mentioned embodiments. For its specific implementation manners, reference may be made to the above-mentioned embodiments, and details are not described herein again in this application.

[0169] In an embodiment of the present application, as Figures 5 to 6 shown, a first connecting block 712 is provided on the second slider 713, and a slot for hanging the door panel 21 is formed on the first connecting block 712.

[0170] In this embodiment, by providing the first connecting block 712 on the second slider 713 and providing a slot on the first connecting block 712, correspondingly, a connecting 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 connecting block 712, enabling the door panel 21 to 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 user's usage requirements in different scenarios.

[0171] According to another embodiment of the present application, in addition to adopting the above structure of double guide rails and double sliders, the sliding mechanism of the present application can also adopt the structure in Figures 8 to 10 . Among them, the sliding mechanism includes a guide member 730, a sliding member 740, a connecting rod assembly 750, and a driving rod 760.

[0172] The guide member 730 is configured to be provided on the cabinet door, and a guiding structure 731 is provided on the guide member 730. The sliding member 740 is configured to be provided on the door panel, and the sliding member 740 is movably provided on the guide member 730 along the width direction of the cabinet door.

[0173] The connecting rod assembly 750 is movably provided on the guiding structure 731 and can be structurally deformed under the guidance of the guiding structure 731. The second end of the connecting rod assembly 750 is movably connected to the sliding member 740.

[0174] The driving rod 760 is provided on the cabinet body and is movably connected to the first end of the connecting rod assembly 750, so as to drive the connecting rod assembly 750 to be structurally deformed during the opening and closing of the cabinet door, and further drive the sliding member 740 to drive the door panel to move along the width direction by the connecting rod assembly 750.

[0175] It is understandable that, as shown in the figure, a hinge is installed on the cabinet body, a hinge shaft is provided on the hinge, and the cabinet door is rotatably provided on the hinge shaft to realize the opening or closing of the cabinet door relative to the cabinet body.

[0176] The guiding structure 731 can ensure that the connecting rod assembly 750 moves along a predetermined path or direction, prevent it from deviating from the predetermined trajectory, and can guide the structural deformation of the connecting rod assembly 750, and further drive the sliding member 740 to move along the width direction of the cabinet door.

[0177] Optionally, the guiding structure 731 can guide the connecting rod assembly 750 to move along the tooth profile of the sprocket through the cooperation of the sprocket and the chain, and the guiding structure 731 can also guide the connecting rod assembly 750 to move along the cross-section of the guide rail through the cooperation of the slider 742 and the guide rail.

[0178] Through its own structural deformation, the connecting rod assembly 750 changes the distance between the second end of the connecting rod assembly 750 and the hinge, thereby driving the change in the distance between the sliding member 740 and the hinge, and further realizing the change in the distance of the door panel connected to the sliding member 740 relative to the hinge.

[0179] Optionally, the connecting rod assembly 750 can be a parallel four-link mechanism or a crank-rocker mechanism.

[0180] For the sliding mechanism shown in this embodiment, by arranging the guiding member 730 on the cabinet door, the sliding member 740 on the door panel, the sliding member 740 is movably arranged on the guiding member 730 along the width direction of the cabinet door, and a guiding structure 731 is arranged on the guiding member 730. The guiding structure 731 can guide the connecting rod assembly 750 to undergo structural deformation, and the second end of the connecting rod assembly 750 is movably connected to the sliding member 740. When the cabinet door is opened, the driving rod 760 drives the first end of the connecting rod assembly 750, the connecting rod assembly 750 undergoes structural deformation, and the second end of the connecting rod assembly 750 pulls the sliding member 740 to move away from the hinge, thereby driving the door panel to move away from the hinge along the width direction of the cabinet door, so that the door panel and the cabinet body on the side are prevented from interfering with the cabinet body; when the cabinet door is closed, the driving rod 760 drives the first end of the connecting rod assembly 750, the connecting rod assembly 750 undergoes structural deformation, and the second end of the connecting rod assembly 750 pulls the sliding member 740 to move towards the hinge, thereby driving the door panel to move towards the hinge along the width direction of the cabinet door, so that the door panel returns to its original position, ensuring that the door panel does not interfere with the cabinet body around the refrigeration equipment.

[0181] In some embodiments, as Figure 8 shown, the connecting rod assembly 750 includes: a first connecting rod 751 and a second connecting rod 752.

[0182] The driving rod 760 is rotatably connected to the first end of the first connecting rod 751, and the second end of the first connecting rod 751 and the first end of the second connecting rod 752 are rotatably connected through a first hinge shaft 753; the first hinge shaft 753 is arranged on the guiding structure 731 and moves along the thickness direction of the door panel under the guidance of the guiding structure 731; the second end of the second connecting rod 752 is rotatably connected to the sliding member 740.

[0183] The driving rod 760 is used to drive the first end of the first link 751 to move in the width direction. The first link 751 is used to drive the first hinge shaft 753 to move in the thickness direction, so as to change the included angle between the first link 751 and the second link 752. Furthermore, the second link 752 drives the sliding member 740 to move along a direction opposite to the driving direction of the driving rod 760.

[0184] It can be understood that the driving rod 760 provides a driving force to the first end of the first link 751. The guiding structure 731 can restrict the movement path of the first hinge shaft 753, so that the first hinge shaft 753 can only move in the thickness direction of the box door. Furthermore, the included angle between the first link 751 and the second link 752 is changed, so that the second link 752 moves in the width direction.

[0185] During the process of the box door opening the box body, the driving rod 760 drives the first end of the first link 751 to move in the width direction towards the direction close to the hinge. The first link 751 drives the first hinge shaft 753 to move in the thickness direction towards the direction close to the sliding member 740, making the included angle between the first link 751 and the second link 752 larger, and pushing the second link 752 to move away from the hinge. Furthermore, the sliding member 740 is driven to move in the width direction away from the hinge, so that the door panel and the cabinet on the side are prevented from interfering with the cabinet.

[0186] During the process of the box door closing the box body, the driving rod 760 drives the first end of the first link 751 to move in the width direction away from the hinge. The first link 751 drives the first hinge shaft 753 to move in the thickness direction away from the sliding member 740, making the included angle between the first link 751 and the second link 752 smaller, and pushing the second link 752 to move towards the hinge. Furthermore, the sliding member 740 is driven to move in the width direction towards the hinge, so that the door panel returns to its original position, ensuring that the door panel does not interfere with the cabinet around the refrigeration equipment.

[0187] In this embodiment, by arranging the first link 751, the second link 752 and the first hinge shaft 753 in the link assembly 750, and restricting the movement of the first hinge shaft 753 in the thickness direction, the included angle between the first link 751 and the second link 752 is changed, so that the second link 752 can drive the sliding member 740 to move in the width direction, realizing the movement of the door panel relative to the box door. The structure is simple and the volume is small.

[0188] In some embodiments, as Figure 8 shown, the driving rod 760 includes: a linkage member.

[0189] The first end of the linkage is configured to be rotatably disposed at a fixed position on the cabinet of the refrigeration device, and the second end of the linkage is rotatably connected to the first end of the first link 751; the fixed position is arranged deviating from the hinge position between the cabinet door and the cabinet body.

[0190] During the process of the cabinet door opening the cabinet body, the linkage is used to drive the first end of the first link 751 to move towards the side close to the hinge position, and the second link 752 drives the sliding member 740 to drive the door panel to move towards the side away from the hinge position.

[0191] During the process of the cabinet door closing the cabinet body, the linkage is used to drive the first end of the first link 751 to move towards the side away from the hinge position, and the second link 752 drives the sliding member 740 to drive the door panel to move towards the side close to the hinge position.

[0192] It can be understood that the first end of the linkage in this embodiment is rotatably disposed on the hinge. When the cabinet door rotates relative to the cabinet body around the hinge axis, the second end of the linkage rotates in a circular motion with the hinge axis as the center. Since the first end of the linkage is arranged offset from the hinge axis, the distance between the second end of the linkage and the hinge will change with the rotation of the linkage, thereby driving the link assembly 750 to move towards or away from the hinge along the width direction of the cabinet door.

[0193] During the process of the cabinet door opening the cabinet body, as the cabinet door rotates, the cabinet door drives the linkage to rotate. The second end of the linkage drives the first end of the first link 751 to move towards the side close to the hinge position, and the second end of the second link 752 drives the sliding member 740 to move towards the side away from the hinge position, thereby causing the door panel to move towards the side away from the hinge position.

[0194] During the process of the cabinet door closing the cabinet body, as the cabinet door rotates, the cabinet door drives the linkage to rotate. The second end of the linkage drives the first end of the first link 751 to move towards the side away from the hinge position, and the second end of the second link 752 drives the sliding member 740 to move towards the side away from the hinge position, thereby causing the door panel to move towards the side close to the hinge position.

[0195] In this embodiment, by arranging the first end of the linkage to deviate from the hinge position between the cabinet door and the cabinet body, the second end of the linkage can drive the first end of the first link 751, enabling the second link 752 to drive the sliding member 740 to move in the width direction. The opening and closing of the cabinet door can control the transmission of the linkage driving the link assembly 750, enabling the sliding member 740 to drive the door panel to move in the width direction without an additional driving device, and can achieve the movement of the door panel relative to the cabinet door to be synchronized with the opening and closing of the cabinet door.

[0196] In some embodiments, as Figure 9 shown, the guiding structure 731 includes: a first limiting groove 7311.

[0197] The first limiting groove 7311 extends in the thickness direction.

[0198] The first hinge shaft 753 is inserted into the first limiting groove 7311 and can move along the extending direction of the first limiting groove 7311.

[0199] It can be understood that the first limiting groove 7311 is used to limit the first hinge shaft 753, so that the first hinge shaft 753 can only move in the thickness direction. Furthermore, the included angle between the first connecting rod 751 and the second connecting rod 752 respectively connected to the first hinge shaft 753 can change, and the moving directions of the second ends of the first connecting rod 751 and the second connecting rod 752 are opposite.

[0200] The first limiting groove 7311 of this embodiment can guide the moving direction of the first hinge shaft 753. Moreover, the first limiting groove 7311 can be directly opened on the upper surface of the guiding member 730 without occupying extra space, ensuring the compactness of the structure of the sliding mechanism.

[0201] In some embodiments, as Figure 9 shown, the guiding structure 731 further includes: a second limiting groove 7312.

[0202] The second limiting groove 7312 extends in the width direction and communicates with the first limiting groove 7311.

[0203] The driving rod 760 is rotatably connected to the first end of the first connecting rod 751 through a second hinge shaft 754, and the second end of the second connecting rod 752 is rotatably connected to the sliding member 740 through a third hinge shaft 755; the second hinge shaft 754 and the third hinge shaft 755 are respectively inserted into the second limiting groove 7312 and can move along the extending direction of the second limiting groove 7312;

[0204] Wherein, the second hinge shaft 754 and the third hinge shaft 755 are respectively arranged on both sides of the first limiting groove 7311.

[0205] It can be understood that the second limiting groove 7312 is used to limit the second hinge shaft 754 and the third hinge shaft 755, so that the second hinge shaft 754 and the third hinge shaft 755 can only move in the width direction. Furthermore, the second connecting rod 752 can drive the sliding member 740 to move in the width direction. The second limiting groove 7312 of this embodiment ensures that the moving direction of the sliding member 740 will not deviate, ensuring the reliability and stability of the moving direction of the sliding member 740, and thus ensuring the reliability of the door panel moving along the width direction of the cabinet door.

[0206] In some embodiments, as Figure 8 shown, the sliding mechanism further includes: an elastic member 770.

[0207] The elastic member 770 is disposed between the guiding member 730 and the sliding member 740.

[0208] When the link assembly 750 drives the sliding member 740 to move toward the side away from the hinge position, the sliding member 740 compresses the elastic member 770 during the process of driving the door panel to move.

[0209] When the link assembly 750 drives the sliding member 740 to move toward the side close to the hinge position, the elastic member 770 drives the sliding member 740 to drive the door panel toward the hinge position.

[0210] Wherein, the hinge position is located between the box door and the box body, and the box door is rotatably disposed on the box body based on the hinge position.

[0211] It can be understood that when the link assembly 750 drives the sliding member 740 to move toward the side away from the hinge position, the elastic member 770 is compressed in the direction away from the hinge to accumulate elastic potential energy.

[0212] When the link assembly 750 drives the sliding member 740 to move toward the side close to the hinge position, the elastic potential energy of the elastic member 770 is released, and the elastic force of the elastic member 770 acts on the sliding member 740 to drive the sliding member 740 close to the hinge position.

[0213] Specifically, the elastic member 770 can be an elastic sheet, an elastic block, or a spring.

[0214] In this embodiment, by arranging the elastic member 770 in the sliding mechanism, based on the elastic deformation of the elastic member 770, it can be ensured that the movement of the sliding member 740 relative to the guiding member 730 is more stable and reliable.

[0215] In some embodiments, as Figures 8 to 10 shown, the guiding member 730 includes: a fixing plate 732 and a sliding groove 733.

[0216] The fixing plate 732 is configured to be disposed on the box door.

[0217] The sliding groove 733 is disposed on the fixing plate 732 and extends along the width direction, and at least part of the sliding member 740 is movably disposed in the sliding groove 733 along the width direction.

[0218] It can be understood that the fixing plate 732 of this embodiment is used for fixedly connecting with the box door, and the sliding groove 733 is used for guiding the movement of the sliding member 740 along the width direction of the box door. Based on the sliding fit between the sliding member 740 and the sliding groove 733, it is ensured that the sliding member 740 can move stably and reliably along the width direction of the box door.

[0219] In some embodiments, as Figure 9 and Figure 10As shown, the guide member 730 further includes a sliding sleeve 734 disposed at one end of the chute 733 away from the hinge position.

[0220] The sliding member 740 includes a guide rod 741 and a sliding block 742. The guide rod 741 passes through the sliding sleeve 734. A sliding contact 745 is provided on the guide rod 741 and is movably disposed in the chute 733 in the width direction; the sliding block 742 is connected to the guide rod 741 and is configured to be connected to the door panel.

[0221] Wherein, an elastic member 770 is disposed between the sliding sleeve 734 and the sliding contact 745.

[0222] It can be understood that the chute 733 in this embodiment is arc-shaped to fit the outer wall of the guide rod 741. The sliding sleeve 734 is used to guide the movement of the guide rod 741 relative to the chute 733. And as the sliding member 740 moves on the chute 733, the sliding contact 745 also moves accordingly. The sliding sleeve 734 is fixedly disposed relative to the fixing plate 732. The elastic member 770 is limited between the sliding sleeve 734 and the sliding contact 745. When the guide rod 741 moves toward the side away from the hinge, the sliding contact 745 moves toward the sliding sleeve 734, causing the elastic member 770 between the sliding sleeve 734 and the sliding contact 745 to be compressed. When the guide rod 741 moves toward the side close to the hinge, the elastic member 770 releases elastic potential energy and elongates, and the sliding contact 745 moves in the direction away from the sliding sleeve 734. The sliding sleeve 734 and the sliding contact 745 constrain the elastic member 770 from both sides of the elastic member 770 to ensure the reliability of the compression and elongation of the elastic member 770.

[0223] And, one end of the sliding block 742 is connected to the guide rod 741, and the other end is connected to the door panel, so that when the guide rod 741 moves in the width direction of the cabinet door, the sliding can drive the door panel to move in the width direction of the cabinet door.

[0224] In some embodiments, as Figure 8 shown, the elastic member 770 includes a spring sleeved on the outer side of the guide rod 741 and limited between the sliding sleeve 734 and the sliding contact 745.

[0225] It can be understood that when the elastic member 770 is set as a spring, the hollow structure of the spring enables the spring to be sleeved on the outer wall of the guide rod 741. And in the length direction of the guide rod 741, the state of compression and elongation of the spring changes. And the sliding sleeve 734 and the sliding contact 745 can limit both sides of the spring from both ends of the guide rod 741, which is convenient for stopping at both ends when the spring is compressed and elongated. The spring in this embodiment makes the structure simple and compact when the door panel is reset relative to the cabinet door, with a small volume and saves the installation space of the door panel.

[0226] In some embodiments, asFigure 8 and Figure 9 As shown in Figure 9 , the sliding member 740 further includes a first connecting arm 743 and a second connecting arm 744.

[0227] The first connecting arm 743 and the second connecting arm 744 are arranged at intervals in the width direction. The first end of the guide rod 741 is connected to the first end of the sliding block 742 through the first connecting arm 743, and the second end of the guide rod 741 is connected to the second end of the sliding block 742 through the second connecting arm 744.

[0228] The sliding sleeve 734 and the sliding contact 745 are located between the first connecting arm 743 and the second connecting arm 744.

[0229] It can be understood that the first connecting arm 743 and the second connecting arm 744 connect the guide rod 741 and the sliding block 742 respectively from both ends of the guide rod 741 and the sliding block 742, making the connection between the guide rod 741 and the sliding block 742 relatively firm. And when the sliding block 742 moves along the width direction of the door of the box, it is easier to fit the width direction.

[0230] Furthermore, in this embodiment, the sliding block 742 is perpendicularly arranged with the first connecting arm 743 and the second connecting arm 744. When the door panel is installed on the sliding block 742, the fixing plate 732 is installed at the top of the door of the box. The door panel and the door of the box can be parallel and fit, ensuring the flatness of the door panel installed on the door of the box. And it is beneficial for the door panel to move along the door of the box.

[0231] Of course, in addition to adopting the above forms of slide rails and sliders or link forms, the sliding mechanism can also adopt the form of a gear and rack, or the form of a cable structure, etc. The specific structure is not limited, as long as the sliding mechanism can drive the door panel to move relative to the door of the box. Correspondingly, the traction mechanism is not limited by the above examples. For example, the traction mechanism can adopt structural forms such as air cylinders and ropes, and specific examples are not listed one by one. In addition, the traction mechanism can be an electric structure or a mechanical structure.

[0232] In an embodiment of the present application, Figure 4 、 Figure 11 and Figure 12 As shown in Figure 11 and Figure 12 , 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 on the door of the box 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, and a second connecting block 812 is provided on the third slider 813. A slot for hanging the door panel 21 is formed on the second connecting block 812.

[0233] In this embodiment, by providing a first driven guide mechanism 8 parallel to the sliding mechanism on the box door 2, the first driven guide mechanism 8 has a second base 817. A third guide rail and a third slider 813 that can slide along the third guide rail are provided on the second base 817. The third slider 813 is connected to the door panel 21 through a 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 mechanism 8 can cooperate with the sliding mechanism to limit the movement direction of the door panel 21, reducing the shaking of the door panel 21 during the sliding process and making 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 mechanism.

[0234] Further, the first driven guide 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 limit slots similar to those of the first fixing seat 701 and the second fixing seat 702.

[0235] Specifically, the third fixing seat 801 is provided with a third fixing hole, and the second base 817 is provided with a third waist-shaped hole extending along the width direction of the second base 817; a third adjusting member 804 passes through the third fixing hole and is slidably disposed in the third waist-shaped hole to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0236] It can be understood that the fourth fixing seat 802 can also be provided with a third fixing hole; the second base 817 is provided with a third waist-shaped hole extending along the width direction of the second base 817; a third adjusting member 804 passes through the third fixing hole and is slidably disposed in the third waist-shaped hole to adjust the position of the third adjusting member 804 in the third waist-shaped hole

[0237] Further, the third fixing seat 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. A 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 to adjust the position of the third fixing seat 801 relative to the external structure by the position of the fourth adjusting member 803 in the fourth waist-shaped hole.

[0238] It can be understood that the fourth fixing seat 802 can also be provided with a fourth waist-shaped hole extending along the width direction of the third base 902; a 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 to adjust the position of the fourth fixing seat 802 relative to the external structure by the position of the fourth adjusting member 803 in the fourth waist-shaped hole.

[0239] In an embodiment of the present application, as Figure 4 , Figure 13 and Figure 14 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, 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 arranged on the fourth slider 903, and a slot for hanging the door panel 21 is formed on the third connecting block 905.

[0240] In this embodiment, by arranging 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 role of supporting and assisting the sliding of the door panel 21, so that the door panel 21 slides more stably and smoothly relative to the box door 2.

[0241] At the same time, since the second driven guide rail mechanism 9 is arranged coaxially with the sliding mechanism, the third connecting block 905 can cooperate with the sliding mechanism 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.

[0242] In an embodiment of the present application, as Figure 13 and Figure 14 shown, both ends of the third base 902 of the second driven guide rail mechanism 9 are respectively provided with a fifth fixing seat 901 and a sixth fixing seat 904 for fixedly connecting with the box door 2.

[0243] Furthermore, in an embodiment of the present application, as Figure 4 , Figures 11 to 14 shown, the sliding mechanism, 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 mechanism are arranged in parallel, and the second driven guide rail mechanism 9 is arranged coaxially with the sliding mechanism.

[0244] It can be understood that the width direction of the box door 2 is parallel to the plane where the box door 2 is located and perpendicular to the rotating shaft of the box door 2, so that the door panel 21 can be far away from or close to the rotating shaft of the box door 2.

[0245] In this embodiment, by arranging the first driven guide rail mechanism 8 parallel to the sliding mechanism, the third slider 813 can slide parallel to the sliding mechanism, better assisting the door panel 21 to slide relative to the cabinet door 2 under the drive of the sliding mechanism. At the same time, the second connecting block 812 can cooperate with the sliding mechanism 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, the third connecting block 905 can cooperate with the sliding mechanism 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.

[0246] In one embodiment of the present application, as Figures 17 to 20 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 cabinet door 2, and a first installation groove 213 is formed on the first end cover 210. The sliding mechanism 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 cabinet 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.

[0247] In this embodiment, by respectively arranging the first end cover 210 and the second end cover 220 at both ends of the cabinet door 2, and forming the first installation groove 213 on the first end cover 210 to install the sliding mechanism and the first driven guide rail mechanism 8, and forming the second installation groove on the second end cover 220 to install the second driven guide rail mechanism 9, the structures of the sliding mechanism, the first driven guide rail mechanism 8, the second driven guide rail mechanism 9 and the cabinet door 2 are made more compact and beautiful.

[0248] Optionally, in one embodiment of the present application, as Figure 18 shown, both the first driven guide rail mechanism 8 and the second driven guide rail mechanism 9 are arranged along the width direction of the cabinet door 2. The sliding mechanism and the first driven guide rail mechanism 8 are arranged on the top of the cabinet door 2, and the second driven guide rail mechanism 9 is arranged on the bottom of the cabinet door 2.

[0249] In this embodiment, by arranging the sliding mechanism and the first driven guide rail mechanism 8 on the top of the cabinet door 2 and the second driven guide rail mechanism 9 on the bottom of the cabinet door 2, the top of the cabinet door 2 is connected to the door panel 21 through the sliding mechanism and the first driven guide rail mechanism 8, and the bottom of the cabinet door 2 is connected to the door panel 21 through the second driven guide rail mechanism 9, so that the connection between the door panel 21 and the cabinet door 2 is more stable and reliable.

[0250] It is understandable that in another embodiment of the present application, both 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 sliding mechanism and the first driven guide rail mechanism 8 are arranged at the bottom of the corresponding door 2, and the second driven guide rail mechanism 9 of the first door body assembly is arranged at the top of the corresponding door 2.

[0251] In this embodiment, by arranging the sliding mechanism and the first driven guide rail mechanism 8 at the bottom of the door 2 and the second driven guide rail mechanism 9 at the top of the door 2, the top of the door 2 is connected to the door panel 21 through the sliding mechanism, the first driven guide rail mechanism 8, and the bottom of the door 2 is connected to the door panel 21 through the second driven guide rail mechanism 9, so that the connection between the door panel 21 and the door 2 is more stable and reliable.

[0252] Furthermore, as Figure 21 , Figure 23 , Figure 24 , Figure 26 and Figure 27 shown, in an embodiment of the present application, the door body assembly further includes: a first main decorative cover 13 and a second main decorative cover 14. The first main decorative cover 13 is detachably arranged on the first end cover 210, and is formed with a first notch 1303 and a second notch 1304. One end of the first connecting block 712 provided with a slot passes through the first notch 1303, and one end of the second connecting block 812 provided with a slot passes through the second notch 1304. The second main decorative cover 14 is detachably arranged on the second end cover 220, and is formed with a third notch 1401. One end of the third connecting block 905 provided with a slot passes through the third notch 1401.

[0253] In this embodiment, by arranging the first main decorative cover 13 on the door 2, the first main decorative cover 13 can cover the entire sliding mechanism and the first driven guide rail mechanism 8, preventing the sliding mechanism and the first driven guide rail mechanism 8 from being completely exposed, making it more beautiful. At the same time, the first main decorative cover 13 is formed with a first notch 1303 and a second notch 1304, so that the sliding mechanism and the first driven guide rail mechanism 8 can extend to the outside of the first main decorative cover 13 through the first notch 1303 and the second notch 1304 respectively to be connected to the door panel 21 to achieve the function of driving the door panel 21 to slide. By detachably arranging the second main decorative cover 14 on the door 2 to cover the second driven guide rail mechanism 9, preventing the second driven guide rail mechanism 9 from being exposed, making the entire door 2 more beautiful. The second driven guide rail mechanism 9 passes through the third notch 1401, and the second driven guide rail mechanism 9 is used to connect to the door panel 21, so that the second driven guide rail mechanism 9 can cooperate to guide the movement of the door panel 21 relative to the door 2 during the opening or closing process of the door 2.

[0254] It is understandable that the colors and materials of the first main decorative cover 13 and the second main decorative cover 14 in this embodiment can be designed according to the needs of users, and cooperate with the materials and colors of the outer surface of the box door 2 (for example, be kept consistent or cooperate with the outer surface of the box door 2 to form a decorative pattern) to improve the overall aesthetics of the cabinet body.

[0268] It can be understood that the positions of the second protrusion and the second groove can be interchanged, that is, the second end cover 220 is provided with a first groove, and the second auxiliary decorative cover 18 is provided with a second protrusion.

[0269] In some embodiments, at least one of the first end cover 210, the second end cover 220, the first auxiliary decorative cover 17 and the second auxiliary decorative cover 18 is provided with a handle slot for the user to open or close the box door 2.

[0270] In this embodiment, by providing a handle groove on at least one of the first end cover 210, the second end cover 220, the first auxiliary decorative cover 17, and the second auxiliary decorative cover 18, it is convenient for the user to insert their hand into the handle groove, facilitating the user to manually open or close the door 2. The structure is simple and the operation is convenient.

[0271] It can be understood that as Figure 28 shown, when the door panel 21 does not need to be installed, the second driven guide rail mechanism 9 in the second installation groove can be removed. Correspondingly, the second auxiliary decorative cover 18 is provided with an inwardly concave handle portion 1801 at the position corresponding to the second installation groove, facilitating the user to manually open and close the door 2.

[0272] In an embodiment of the present application, as Figure 15 and Figure 16 shown, a first hook 2111 is provided at the top of the door panel 21, and a second hook 2112 is provided at the bottom of the door panel 21. The length of the second hook 2112 is greater than the length of the first hook 2111. The first hook 2111 and the second hook 2112 are adapted to be inserted into the corresponding slots.

[0273] In this embodiment, by respectively providing the first hook 2111 and the second hook 2112 at the top and bottom of the door panel 21, the door panel 21 can be connected to the slots on the sliding mechanism and the two driven guide rail mechanisms through the first hook 2111 and the second hook 2112, thereby slidably connecting the door panel 21 to the door 2. The first hook 2111 and the second hook 2112 are respectively located at the top and bottom of the door panel 21, making it not easy for the door panel 21 to shake.

[0274] In addition, the length of the second hook 2112 is greater than the length of the first hook 2111. When installing the door panel 21 on the outside of the door 2, the slot at the bottom first engages with the second hook 2112 of the door panel 21 to initially position the bottom of the door panel 21. Then, adjust the position and angle of the door panel 21 so that the first hook 2111 at the top of the door panel 21 is inserted into the slot at the top of the door 2. This makes it easier for the user to align the slots with the first hook 2111 and the second hook 2112, and the installation is more convenient.

[0275] Specifically, the first hook 2111 includes a connecting portion and a hook portion provided on the connecting portion. The hook portion is in the shape of a hook and is used for engaging with the slot. The connecting portion is provided with at least one waist-shaped hole extending in the horizontal direction and at least one waist-shaped hole extending in the vertical direction. Corresponding to the first hook 2111 on the door panel 21, there are fixing holes. The door panel 21 and the first hook 2111 are fixedly connected by fixing members passing through the waist-shaped holes and the fixing holes. By adjusting the position of the fixing member in the waist-shaped hole, the position of the first hook 2111 can be finely adjusted, facilitating the installation of the door panel 21 and finely adjusting the position and angle of the door panel 21.

[0276] It is understandable that the structure of the second hook 2112 is similar to that of the first hook 2111, and will not be elaborated here.

[0277] In an embodiment of the present application, the door body assembly and the box body 1 are configured to be arranged in the installation space formed between the first cabinet body and the second cabinet body; during the opening or closing process of the box door 2, the sliding mechanism 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 walls of the first cabinet body and the second cabinet body.

[0278] In this embodiment, the box body 1 is arranged between the first cabinet body and the second cabinet body. It is understandable 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 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 can maintain visual consistency and have a smaller gap, which is more beautiful.

[0279] When the box door 2 rotates outward to open, the sliding mechanism 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 near the first hinge 4 and causing the box door 2 to not be able to open to a larger angle. When the box door 2 rotates to close, the sliding mechanism 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 far from the first hinge 4 and causing the box door 2 to not be able to close completely, which affects the function of the box body 1. And when the box door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet body again. 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 box door 2.

[0280] In another embodiment of the present application, the door body assembly and the box body 1 are configured to be arranged in the cabinet; during the opening or closing process of the box door 2, the sliding mechanism 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.

[0281] In this embodiment, the box body 1 is arranged in a single cabinet. It is understandable 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 box 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 smaller gap, which is more beautiful.

[0282] When the cabinet door 2 rotates outward to open, the sliding mechanism 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 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 the state flush with the cabinet body again. 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.

[0285] By arranging the door panel 21 on the cabinet door 2, when the refrigeration device is an embedded type and is arranged in a groove-shaped space, or is arranged between two cabinet bodies, the door panel 21 can be arranged flush with the groove side wall or the two cabinet bodies on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet body, making it more beautiful.

[0286] At the same time, when the cabinet door 2 rotates, the sliding mechanism can drive the door panel 21 to move relative to the cabinet door 2 during the rotation process of the cabinet door 2 to move as far as possible away from obstacles such as the wall or cabinet body on the side of the cabinet body 1 side door, so as to prevent these obstacles from blocking the door panel 21 and affecting the rotation of the cabinet door 2, resulting in the cabinet door 2 being unable to be normally opened or closed.

[0287] The combination of the cabinet door 2 and the door panel 21 enables the refrigeration device to avoid interference between the door panel 21 and surrounding objects when opening and closing, greatly improving the use convenience. Especially in a narrow kitchen environment, this design advantage is more obvious.
