[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 appliance and the side wall of the cabinet is required to be higher to further improve the home integration effect. This leads to the situation that after the 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, resulting in the door body assembly of the appliance being unable to be normally opened or closed.

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.

[0105] In today's society, the rapid progress of technology has greatly promoted the transformation of home living styles. Among them, built-in furniture, as a design concept that combines beauty and practicality, is favored by the majority of consumers. By cleverly 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. Take the 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 and creating a modern and harmonious living environment. However, although the built-in refrigerator shows significant advantages in enhancing home aesthetics and space utilization, there is still a problem that cannot be ignored in its actual use: 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 user experience of the built-in refrigerator.

[0106] Specifically, when the built-in refrigerator (referred to as the refrigerator for short) meets the user's different usage requirements for both fully flush and fully built-in refrigerators at the same time, after the refrigerator door body (referred to as the door for short) is connected to the cabinet door panel (referred to as the panel for short), the entire door body assembly becomes thicker. 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 structure hinges of the refrigerator, the door body assembly with the cabinet door interferes with the cabinet during the process of opening and closing the door, resulting in abnormal opening and use. Therefore, this application proposes a door body assembly that allows 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 of opening the door (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 requirements with or without the panel.

[0107] For aesthetic reasons, the gap between the door panels of the same row of cabinets should not be too large. Therefore, in the initial stage when the door panel is just opened, there is a possibility that the relatively sliding door panel will interfere with the cabinet panels on both sides at the same time. After the door body is opened to a certain angle, there is a possibility that the hinge side of the door panel will interfere with the cabinet panel at this time.

[0108] Based on this, the present application proposes a door body assembly of an embedded refrigeration device (hereinafter referred to as the door body assembly), which can meet the requirements that neither the opening side nor the hinge side of the door panel interferes.

[0109] Combined with Figures 1 to 3 , the door body assembly of the embodiment of the present application includes a box door 2 and a door panel 21. The box door 2 is rotatably connected to the refrigeration box body 1. Among them, the refrigeration box body 1 is used to be 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. In the following, the installation body is taken as the cabinet 60 as an example for description. The door panel 21 is movably installed on the box door 2, and the door panel 21 can move along the width direction of the box door 2. During the opening process of the box door 2, the door panel 21 is adapted to move towards the opening side of the box door 2.

[0110] Combined with Figure 2 and Figure 3 , when the box door 2 is closed, the distance between the end face of the opening side of the door panel 21 and the corresponding side wall of the accommodation space is δ1, and the distance between the end face of the hinge side of the door panel 21 and the corresponding side wall of the accommodation space is δ2. Among them, δ1 is 0.5 mm - 6 mm, and the distance between the end face of the hinge side of the door panel and the corresponding side wall of the accommodation space is δ2 is 0.5 mm - 6 mm

[0111] In this case, the installation requirements of the door body assembly can be met, the hidden installation of the refrigeration device can be ensured, and at the same time, during the opening process, it can be ensured that the door body assembly does not interfere with the installation body, improving the user experience.

[0112] According to the embodiment of the present application, the door panel 21 has a first interference position c point and a second interference position d point. The first interference position is located at the inner corner of the opening side of the door panel 21, and the second interference position is located at the outer corner of the hinge side of the door panel 21. The "inner" and "outer" here are relative to the refrigeration box body 1. The side facing the refrigeration box body 1 is the "inner" side, and the side facing away from the refrigeration box body 1 is the "outer" side. Since Figure 2 and Figure 3 are top views, the first interference position and the second interference position are from Figure 2 and Figure 3When viewed, it is a point. It can be understood that for the door body assembly, the first interference position and the second interference position are respectively a vertical line. Among them, if the inner corner on the opening side is arc-shaped, the first 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. Similarly, if the outer corner on the hinge side of the door panel 21 is arc-shaped, the second 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.

[0113] According to an embodiment of the present application, the vertical distance from the hinge axis of the box door to the inner surface of the door panel is l1, the vertical distance from the hinge axis of the box door to the end face of the opening side of the door panel is l2, the vertical distance from the hinge axis of the box door to the end face of the hinge side of the door panel is l3, and the thickness of the door panel is h. l1 is 5 mm - 50 mm, l2 is 240 mm - 700 mm, l3 is (300 mm to 700 mm) minus l2, and h is 10 mm to 25 mm. In this case, the overall size of the door body assembly obtained is appropriate, and it is easy to ensure the secrecy of the refrigeration equipment and prevent interference of the door body assembly. Among them, the commonly used values of l2 include 597 mm, 600 mm, 747 mm, 750 mm, 607 mm, 610 mm. The commonly used values of h include 16 mm, 18 mm, 20 mm, 22 mm, 25 mm.

[0114] According to an embodiment of the present application, for every 0.5° increase in the opening angle of the door body assembly, the change in the moving distance Δs does not exceed 3 mm. That is, to ensure that the movement of the door panel is as uniform as possible, prevent the door panel from suddenly moving at a large angle, and thus make the movement of the door panel as concealed as possible to prevent users from panicking about the movement of the door panel.

[0115] According to an embodiment of the present application, before the first interference position leaves the accommodation space, the moving distance Δs does not exceed 5 mm. For example, the angle corresponding to the first interference position leaving the accommodation space is 2° - 5°. Since Δs is small during this process, interference between the door panel and the accommodation space can be avoided.

[0116] In one embodiment, when the opening angle Δθ of the door body assembly is 0.5°, the moving distance Δs is 0.3 mm to 0.5 mm, and for every 0.5° increase in the opening angle of the door body assembly, the change in the moving distance Δs does not exceed 3 mm.

[0117] According to an embodiment of the present application, the relevant parameters during the opening process of the door body assembly can be referred to the following table:

[0118]

[0119] Table 1

[0120] Among them, δ1 is greater than the movement distance γ of the first interference position along the width direction of the accommodation space before leaving the accommodation space, and γ is also the vertical distance that the first interference position moves towards the side wall of the corresponding accommodation space. δ2 is greater than the movement distance λ of the second interference position along the width direction of the accommodation space before leaving the accommodation space, and λ is also the vertical distance that the second interference position moves towards the side wall of the corresponding accommodation space. Among them, when the door 2 is in the closed position, the width direction of the door 2 is consistent with the width direction of the accommodation space. As the door 2 is opened, at this time, an angle is formed between the width direction of the door 2 and the width direction of the accommodation space.

[0121] According to the embodiments of the present application, first determine that the positions on the door panel 21 that are most likely to interfere are the first interference position and the second interference position respectively, and determine the positions of the first interference position and the second interference position on the door panel 21. On this basis, determine the conditions that need to be satisfied for the first interference position not to interfere, and determine the conditions that need to be satisfied for the second interference position not to interfere, so as to determine the law that needs to be satisfied between the initial clearances (δ1 and δ2) on both sides of the door body assembly and the movement of the door panel 21 to ensure the normal use of the built-in refrigeration equipment.

[0122] According to the embodiments of the present application, when the size of the door body assembly is limited to the size in Table 1 above, γ is between -24 mm and 0.4 mm, λ is between -1 mm and 2.2 mm, and γ ≤ δ1, λ ≤ δ2.

[0123] According to the embodiments of the present application, when the size of the door body assembly is limited to the size in Table 1 above, during the opening process of the door panel assembly, the angle between the connection line of the first interference position and the hinge axis of the door and the horizontal position is set as α, and the angle between the connection line of the second interference position and the hinge axis of the door and the horizontal position is set as β. The included angle α is 2.4° - 21°, and the included angle β is 66° to 72°.

[0124] On this basis, on the premise of ensuring that the door body assembly does not interfere, in order to ensure the beauty and use safety of the built-in refrigeration equipment, as mentioned above, the initial clearances δ1 and δ2 on both sides of the door panel 21 generally do not exceed 6 mm. The embodiments of the present application further give the upper limit values of δ1 and δ2.

[0125] According to the embodiments of the present application, δ1 satisfies: δ1 ≤ γmax.

[0126] γmax is the upper limit value of δ1, corresponding to the value of γ when λ is zero and Δθ is Δθcrit.

[0127] Among them, in combination with Figure 2 and Figure 3, γ is the vertical distance that the first interference position moves towards the side wall of the accommodating space corresponding thereto, λ is the vertical distance that the second interference position moves towards the side wall of the accommodating space corresponding thereto, Δθ is the angle of rotation during the opening process of the cabinet door 2, and Δθ when the first interference position leaves the accommodating space is Δθcrit. Herein, "when the first interference position leaves the accommodating space" corresponds to Figure 2 and Figure 3 the situation where point C in Figure 2 is flush with point e of the cabinet 60, that is, the interference position point c is located on the horizontal line where point e is located. γ is positively correlated with Δs, and Δs is the distance that the door panel 21 moves relative to the opening side of the cabinet door 2 during the opening process of the cabinet door 2.

[0128] Wherein, λ being zero means that at this time δ2 can take the value of zero, that is, the initial gap between the hinge side of the door panel 21 and the second cabinet board 602 can be zero or infinitely close to zero. At this time, in order to ensure that the hinge side of the door panel 21 does not interfere with the second cabinet board 602, the corresponding γmax on the opening side of the door panel 21 is the maximum γmax required, and then the maximum value of δ1 does not need to exceed γmax.

[0129] According to the embodiment of the present application, the spacing δ2 satisfies: δ2 ≤ λmax.

[0130] Wherein, combining Figure 2 and Figure 3 , λ max is the value of λ corresponding to γ being zero and Δθ being Δθcrit. Herein, when γ is zero, the initial gap δ1 on the opening side of the door panel 21 can be zero or infinitely close to zero. In this case, when Δθ is Δθcrit, the displacement of the hinge side of the door panel 21 is λmax. In order to ensure that the hinge side of the door panel 21 does not interfere with the second cabinet board 602, the corresponding λmax on the hinge side of the door panel 21 is the maximum λmax required.

[0131] Combining Figure 2 and Figure 3 , the hinge axis 101 of the cabinet door 2 corresponds to point o in the figure, l1 is the vertical distance from the hinge axis 101 of the cabinet door 2 to the inner surface of the door panel 21, l2 is the vertical distance from the hinge axis 101 of the cabinet door 2 to the end face of the opening side of the door panel 21, l3 is the vertical distance from the hinge axis 101 of the cabinet door 2 to the end face of the hinge side of the door panel 21, h is the thickness of the door panel 21, and Δs is the distance that the door panel 21 moves relative to the cabinet door 2 during the opening process of the cabinet door 2.

[0132] Figure 2 and Figure 3In this case, the positional relationship (represented by dashed lines in the figure) and angular relationship between the refrigeration device (refrigerator) when the door is initially not opened and when the door 2 is opened to any angle are simplified and annotated. In the figure, the corners that may interfere during the door opening process are marked with black dots. Among them, the first interference position c point is prone to interfere with the e point on the outer side of the right end of the first cabinet board 601. That is, the e point is the critical point where the c point gets rid of interference (leaves the accommodation space) during the door opening and closing process. The second interference position d point is the corner point on the outer side of the right end of the door panel 21, and it is the corner point where the right end face of the door panel 21 first interferes with the left end face of the adjacent second cabinet board 602 on the right side during the door opening and closing process. As can be seen from the figure, at the initial position, on the left side of the hinge axis 101, the included angle between the hypotenuse oc where the c point and the hinge axis 101 (point o) are located and the inner side of the door panel is θ0. When the door 2 is opened to any position, the angle is Δθ. At this position, the hypotenuse oc, the distance l2, and the distance l1 are represented by dashed lines; at the initial position, on the right side of the hinge axis 101, the hypotenuse where the d point and the hinge axis 101 are located is od. When the angle of the door 2 is opened to any position and is Δθ, at this position, the hypotenuse od, the distance l1 + h, and the distance l3 are represented by dashed lines; as can be seen from the figure, during the opening process of the door 2, if the door panel does not move along the door 2 towards the door opening side, as the opening angle increases, the d point will quickly interfere with the left end face of the second cabinet board 602, resulting in the inability to open the door 2. Therefore, in order to avoid interference and affect the door opening, during the door opening process, when the opening angle of the door body is Δθ, the corresponding door panel 21 needs to move a distance of Δs towards the door opening side.

[0133] According to the embodiments of the present application, it can be understood that the larger l1, l3, and h are, the easier it is for the door panel 21 to interfere at this time. Thus, l1, l3, h, and δ1 are positively correlated. In addition, δ1 is positively correlated with the maximum Δs before the first interference position leaves the accommodation space. That is, when the first interference position leaves the accommodation space, the larger the relative movement distance Δs of the door panel 21 with respect to the door 2, the larger δ1 means at this time, to prevent the door panel 21 from hitting the first cabinet board 601 during movement. The larger Δs is before the first interference position leaves the accommodation space, the less likely the hinge side of the door panel 21 is to interfere at this time. That is, δ2 can be designed to be smaller at this time. That is, Δs before the first interference position leaves the accommodation space and δ2 are negatively correlated.

[0134] According to the embodiments of the present application, assuming that after the door panel 2 moves a distance of Δs, the length of the side where the c point and the hinge axis 101 (that is, point o) are located is set to a, and the included angle between it and the horizontal line in the figure is set to α. At this time, the length of the side where the d point and the hinge axis 101 (that is, point o) are located is set to b, and the included angle between it and the horizontal line in the figure is set to β.

[0135] In one embodiment, δ1 ≥ γ = a × cosα - l2.

[0136] Among them,

[0137] As described above, Δθ is the angle of rotation during the opening of the cabinet door 2, and Δs is the distance that the door panel 21 moves relative to the opening side of the cabinet door 2 during the opening of the cabinet door 2.

[0138] Thus, when l1 and l2 are determined, the relationship between δ1 and Δs can be obtained. Among them, when Δs is determined, Δθcrit can be obtained, where Δθcrit is the value of Δθ when the first interference position leaves the accommodation space.

[0139] In one embodiment, δ2≥λ = b*cosβ - l3.

[0140] Among them,

[0141] Thus, when l1 and l3 are determined, the relationship between δ2 and Δs can be obtained. Among them, when δ1 and δ2 are equal, that is, the initial gaps on both sides of the door panel 21 are equal, at this time, the value range of Δs can be obtained, and further the value ranges of δ1 and δ2 can be obtained.

[0142] The above formulas for calculating δ1 and δ2 do not constitute a limitation on δ1 and δ2. For example, the above calculation formulas may also have correction factors or correction parameters. In addition, the above calculation formulas are for the case where the hinge axis 101 is determined. If the cabinet door 2 is installed with a double-axis hinge or a movable hinge, at this time, the hinge axis 101 will change with the opening of the cabinet door 2, and then the calculation formulas for δ1 and δ2 also change adaptively, and the moving distance of the hinge axis 101 needs to be calculated in the formula. In addition, if there is an installation gap between the door panel 21 and the cabinet door 2, then h in the above calculation formula is the distance between the sliding surface of the door panel 21 and the outer surface of the door panel 21, and l1 is the distance from the hinge point of the cabinet door 2 to the sliding surface of the door panel 21.

[0143] According to the embodiments of the present application, δ1 = δ2, and γ = λ. Furthermore, at this time, the initial gaps on both sides of the door panel 21 and the cabinet 60 are equal, ensuring the beauty of the built-in refrigeration device. And when δ1 = δ2, at this time, the respective values of γ and λ can be obtained. Of course, δ1 and δ2 can also be unequal, and at this time, γ and λ can correspondingly be unequal. Among them, the larger δ1 is, the smaller δ2 can be. Similarly, the smaller δ2 is, the larger δ2 can be at this time.

[0144] According to an embodiment of the present application, during the installation of the built-in refrigeration device, δ1 and δ2 can be manually controlled. Of course, limit components can also be respectively provided on the door-opening side and the hinge side of the built-in refrigeration device to ensure that during the installation process, the initial gap between the door-opening side of the door panel 21 and the cabinet 60 is δ1, and the initial gap between the hinge side of the door panel 21 and the cabinet 60 is δ2. Alternatively, there can be auxiliary installation tools, the sizes of which respectively correspond to the sizes of δ1 and δ2. Then, during the installation process, through the auxiliary installation tools, ensure that the initial gap between the door panel 21 and the cabinet 60 meets the above settings.

[0145] According to an embodiment of the present application, the relative movement between the door panel 21 and the box door 2 is determined by a sliding mechanism or a traction mechanism that drives the sliding mechanism to move. In the case where the relative movement between the door panel 21 and the box door 2 is determined by the sliding mechanism, once the sliding mechanism is determined, at this time, the movement amount Δs of the door panel 21 is determined. Then, at this time, the value ranges of δ1 and δ2 can be obtained from Δs.

[0146] Alternatively, according to an embodiment of the present application, when δ1 and δ2 are determined, in this case, the functional relationship of Δs can be determined from δ1 and δ2. Then, based on Δs, a sliding mechanism or a traction cabinet that meets the requirements can be obtained. Or, when the width of the accommodation space is determined and all components of the door body assembly except Δs are determined, at this time, the specific value of δ1 + δ2 can be obtained. Then, based on δ1 + δ2, Δs at this time can be obtained. Further, when the width of the accommodation space is determined, at this time, the specific value of δ1 + δ2 can be obtained. And to ensure the beautiful and reliable installation, generally δ1 = δ2. Then, at this time, δ1 and δ2 can be respectively obtained. Then, based on δ1 and δ2, Δs at this time can be obtained.

[0147] According to an embodiment of the present application, the sliding door mechanism 7 includes a sliding mechanism and a traction mechanism.

[0148] According to an embodiment of the present application, please refer to Figures 4 to 5 , 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. The two 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.

[0149] It is understandable that the sliding mechanism of this embodiment can be arranged on the door 2 of the box. One of the first slider 714 and the second slider 713 is in transmission connection with the door 2 or the box body 1, and the other is slidably connected with the door panel 21 arranged outside the door 2. So that when the 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 door 2, so that the door panel 21 can avoid obstacles on both sides during the process of the door 2 rotating and opening / closing.

[0150] Specifically, taking the first slider 714 being connected to the box body 1 through a 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 door 2 of the box. 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 door 2.

[0151] By reasonably setting the extension direction of the flexible cable 706, the first slider 714 and the second slider 713 move in opposite directions when moving, so as to drive the door panel 21 to avoid obstacles.

[0152] For example, during the process of the door 2 rotating and opening towards the outside of the box body 1, the 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 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.

[0153] 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 door 2 or the box body 1 through a traction mechanism, and its working process is the same as that of the above embodiment, and will not be elaborated here.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] It should be noted that in this embodiment, parallelism and perpendicularity should not be in the strict 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.

[0162] 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.

[0163] In this embodiment, by connecting the first flexible cable bypassing one end of the first base 717 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; at the same time, by connecting the second flexible cable bypassing the other end of the first base 717 to the first slider 714 and the second slider 713 respectively, 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. Thus, 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, so that the door panel 21 can slide relative to the door 2 as the door 2 rotates when the door 2 is opened and closed, to avoid interference with obstacles and affect the opening and closing of the door 2.

[0164] 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 small 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.

[0165] Specifically, both the second slider 713 and the first slider 714 are provided with connection heads 711 for fixing the flexible cable 706.

[0166] In an embodiment of the present application, as Figure 5 shown, the sliding mechanism further includes: a first fixed seat 701 and a second fixed seat 702. The first fixed 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 fixed 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.

[0167] In this embodiment, by providing the first fixed seat 701 and the second fixed seat 702 at both ends of the first base 717 respectively, and the first fixed seat 701 and the second fixed 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.

[0168] Specifically, the first fixed 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.

[0169] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the first fixed seat 701 can be adjusted along the width direction of the first base 717, so that the first fixed seat 701 can tighten or loosen the first flexible cable, thereby adjusting the tightness degree of the first flexible cable.

[0170] 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 tension of the first flexible cable is correspondingly adjusted, and the second flexible cable is also correspondingly adjusted in tension under the pulling of the first flexible cable by the first fixing seat 701.

[0171] 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 tension of the second flexible cable by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0172] 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 tension of the second flexible cable.

[0173] 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 tension of the second flexible cable is correspondingly adjusted, and the first flexible cable is also correspondingly adjusted in tension under the pulling of the second flexible cable by the second fixing seat 702.

[0174] 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 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 by the position of the second adjusting member 703 in the second waist-shaped hole.

[0175] 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, thereby being able to cooperate with adjusting the position of the first fixing base 701 relative to the external structure.

[0176] It can be understood that the second fixing base 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 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.

[0177] Furthermore, 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.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] In this embodiment, by fixing the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 to the first slider 714 and the box body 1 respectively, and connecting them through a traction rod 709 between the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, 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, through the transmission connection of the traction rod 709, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, the first slider 714 is pulled, 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.

[0182] 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.

[0183] 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.

[0184] Specifically, during the process of the door 2 rotating and opening towards the outside of the box body 1, the first slider 714 slides towards 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 away from the first hinge 4 through a flexible cable 706, so as to drive the door panel 21 to slide 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 and closing towards one side of the box body 1, the sliding mechanism drives the door panel 21 to slide towards the direction close to the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0185] 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 and opening or closing 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.

[0186] It can be understood that since the sliding mechanism has the beneficial effects of the above embodiments, the door body assembly correspondingly has the beneficial effects of the above embodiments. For its specific implementation manners, reference may be made to the above embodiments, and details will not be elaborated in this application.

[0187] 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.

[0188] 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 also facilitates the user to remove the door panel 21 from the second slider 713 when needed, meeting the user's usage requirements in different scenarios.

[0189] 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.

[0190] The guide member 730 is configured to be provided on the cabinet door. 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.

[0191] The connecting rod assembly 750 is movably provided on the guiding structure 731 and can deform structurally 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.

[0192] The driving rod 760 is provided on the cabinet body and is movably connected to the first end of the connecting rod assembly 750 to drive the connecting rod assembly 750 to deform structurally during the opening and closing of the cabinet door, and then the connecting rod assembly 750 drives the sliding member 740 to drive the door panel to move along the width direction.

[0193] It can be understood that as shown in the figure, a hinge is installed on the cabinet body, and a hinge shaft is provided on the hinge. 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.

[0194] 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 then drive the sliding member 740 to move along the width direction of the cabinet door.

[0195] 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. 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 sliding block 742 and the guide rail.

[0196] Through the structural deformation of the connecting rod assembly 750 itself, the distance between the second end of the connecting rod assembly 750 and the hinge is changed, thereby driving the change in the distance between the sliding member 740 and the hinge, and further realizing the change in the distance between the door panel connected to the sliding member 740 and the hinge.

[0197] Optionally, the connecting rod assembly 750 can be a parallel four-bar linkage or a crank-rocker mechanism.

[0198] For the sliding mechanism shown in this embodiment, by arranging the guide member 730 on the cabinet door, the sliding member 740 on the door panel, the sliding member 740 is movably arranged on the guide member 730 along the width direction of the cabinet door, and a guiding structure 731 is arranged on the guide 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 on the side are prevented from interfering with the cabinet; 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 around the refrigeration equipment.

[0199] In some embodiments, as Figure 8 shown, the connecting rod assembly 750 includes: a first connecting rod 751 and a second connecting rod 752.

[0200] 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.

[0201] 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 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.

[0202] 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 angle between the first link 751 and the second link 752 is changed, so that the second link 752 moves in the width direction.

[0203] 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, so that the angle between the first link 751 and the second link 752 becomes larger, and the second link 752 is pushed 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.

[0204] 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, so that the angle between the first link 751 and the second link 752 becomes smaller, and the second link 752 is pushed 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 is restored to its original position, ensuring that the door panel does not interfere with the cabinet around the refrigeration equipment.

[0205] In this embodiment, by providing the first link 751, the second link 752 and the first hinge shaft 753 in the link assembly 750, and by limiting the movement of the first hinge shaft 753 in the thickness direction, the 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.

[0206] In some embodiments, as Figure 8 shown, the driving rod 760 includes: a linkage member.

[0207] The first end of the linkage is configured to be rotatably disposed at a fixed position on the box body of the refrigeration device, and the second end of the linkage is rotatably connected to the first end of the first connecting rod 751; the fixed position is arranged deviating from the hinge position between the door and the box body.

[0208] During the process of the door opening the box body, the linkage is used to drive the first end of the first connecting rod 751 to move toward the side close to the hinge position, and the second connecting rod 752 drives the sliding member 740 to drive the door panel to move toward the side away from the hinge position.

[0209] During the process of the door closing the box body, the linkage is used to drive the first end of the first connecting rod 751 to move toward the side away from the hinge position, and the second connecting rod 752 drives the sliding member 740 to drive the door panel to move toward the side close to the hinge position.

[0210] It can be understood that the first end of the linkage in this embodiment is rotatably disposed on the hinge. When the door rotates relative to the box 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 as the linkage rotates, thereby driving the connecting rod assembly 750 to move along the width direction of the door toward or away from the hinge.

[0211] During the process of the door opening the box body, as the door rotates, the door drives the linkage to rotate. The second end of the linkage drives the first end of the first connecting rod 751 to move toward the side close to the hinge position, and the second end of the second connecting rod 752 drives the sliding member 740 to move toward the side away from the hinge position, thereby causing the door panel to move toward the side away from the hinge position.

[0212] During the process of the door closing the box body, as the door rotates, the door drives the linkage to rotate. The second end of the linkage drives the first end of the first connecting rod 751 to move toward the side away from the hinge position, and the second end of the second connecting rod 752 drives the sliding member 740 to move toward the side away from the hinge position, thereby causing the door panel to move toward the side close to the hinge position.

[0213] In this embodiment, by arranging the first end of the linkage to deviate from the hinge position between the door and the box body, the second end of the linkage can drive the first end of the first connecting rod 751, enabling the second connecting rod 752 to drive the sliding member 740 to move in the width direction. The opening and closing of the door can control the transmission of the linkage driving the connecting rod assembly 750, enabling the sliding member 740 to drive the door panel to move in the width direction without an additional driving device, and the movement of the door panel relative to the door can be synchronized with the opening and closing of the door.

[0214] In some embodiments, as Figure 9 shown, the guiding structure 731 includes: a first limiting groove 7311.

[0215] The first limiting groove 7311 extends in the thickness direction.

[0216] 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.

[0217] 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.

[0218] 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 additional space, ensuring the compactness of the structure of the sliding mechanism.

[0219] In some embodiments, as Figure 9 shown, the guiding structure 731 further includes: a second limiting groove 7312.

[0220] The second limiting groove 7312 extends in the width direction and communicates with the first limiting groove 7311.

[0221] 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;

[0222] Among them, the second hinge shaft 754 and the third hinge shaft 755 are respectively arranged on both sides of the first limiting groove 7311.

[0223] 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 prevents the moving direction of the sliding member 740 from deviating, ensuring the reliability and stability of the moving direction of the sliding member 740, and thus ensuring the reliability of the movement of the door panel along the width direction of the cabinet door.

[0224] In some embodiments, as Figure 8 shown, the sliding mechanism further includes: an elastic member 770.

[0225] The elastic member 770 is disposed between the guiding member 730 and the sliding member 740.

[0226] 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.

[0227] 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.

[0228] Wherein, the hinge position is located between the cabinet door and the cabinet body, and the cabinet door is rotatably disposed on the cabinet body based on the hinge position.

[0229] 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.

[0230] 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.

[0231] Specifically, the elastic member 770 can be an elastic sheet, an elastic block, or a spring.

[0232] 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.

[0233] In some embodiments, as Figures 8 to 10 shown, the guiding member 730 includes: a fixing plate 732 and a sliding groove 733.

[0234] The fixing plate 732 is configured to be disposed on the cabinet door.

[0235] 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.

[0236] It can be understood that the fixing plate 732 of this embodiment is used for fixedly connecting with the cabinet door, and the sliding groove 733 is used for guiding the movement of the sliding member 740 along the width direction of the cabinet 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 cabinet door.

[0237] 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.

[0238] 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.

[0239] Wherein, an elastic member 770 is disposed between the sliding sleeve 734 and the sliding contact 745.

[0240] It can be understood that the chute 733 in this embodiment is arc-shaped to be adapted to 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.

[0241] 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.

[0242] In some embodiments, as Figure 8 shown, the elastic member 770 includes a spring. The spring is sleeved on the outer side of the guide rod 741 and is limited between the sliding sleeve 734 and the sliding contact 745.

[0243] 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 the spring changes in terms of compression and elongation. Moreover, the sliding sleeve 734 and the sliding contact 745 can limit both sides of the spring from both ends of the guide rod 741, facilitating the stopping of both ends of the spring during compression and elongation. 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 saving the installation space of the door panel.

[0244] 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.

[0245] 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.

[0246] The sliding sleeve 734 and the sliding contact 745 are located between the first connecting arm 743 and the second connecting arm 744.

[0247] 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 box door, it is easier to fit the width direction.

[0248] Further, the sliding block 742 of this embodiment 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 box door, and the door panel and the box door can be parallel and fitted, ensuring the flatness of the door panel installed on the box door. And it is beneficial for the door panel to move along the box door.

[0249] 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 box door. Correspondingly, the traction mechanism is not limited to the above examples. For example, the traction mechanism can adopt structural forms such as cylinders and ropes, and will not be listed one by one here. In addition, the traction mechanism can be an electric structure or a mechanical structure.

[0250] 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 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 the door panel 21 is formed on the second connecting block 812.

[0251] In this embodiment, by providing a first driven guide rail mechanism 8 parallel to the sliding mechanism on the box door 2, the first driven guide rail 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 rail mechanism 8 can cooperate with the sliding mechanism 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.

[0252] Further, 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 limit slots similar to those of the first fixing seat 701 and the second fixing seat 702.

[0253] 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.

[0254] 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

[0255] Further, a fourth waist-shaped hole extending along the width direction of the second base 817 is provided on the third fixing seat 801. A fourth fixing hole is provided on the second base 817. A fourth adjusting member 803 passes through the fourth waist-shaped hole and the fourth fixing hole in sequence and is fixed in 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.

[0256] It can be understood that a fourth waist-shaped hole extending along the width direction of the third base 902 can also be provided on the fourth fixing seat 802; a fourth adjusting member 803 passes through the fourth waist-shaped hole and the fourth fixing hole in sequence and is fixed in 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.

[0257] 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 provided on the fourth slider 903. Slots for hanging the door panel 21 are formed on the third connecting blocks 905.

[0258] 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 in supporting and assisting 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.

[0259] 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 making the sliding process more stable and reliable.

[0260] In an embodiment of the present application, as Figure 13 and Figure 14 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.

[0261] Further, 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. The second driven guide rail mechanism 9 is arranged coaxially with the sliding mechanism.

[0262] 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 move away from or close to the hinge axis of the box door 2.

[0263] 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 box 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 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.

[0264] In an 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 box 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 box 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.

[0265] In this embodiment, by respectively arranging the first end cover 210 and the second end cover 220 at both ends of the box door 2, and forming a 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 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, the first driven guide rail mechanism 8, the second driven guide rail mechanism 9 and the box door 2 are made more compact and beautiful.

[0266] Optionally, in an 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 box door 2. The sliding mechanism and the first driven guide rail mechanism 8 are arranged on the top of the box door 2, and the second driven guide rail mechanism 9 is arranged on the bottom of the box door 2.

[0267] In this embodiment, by arranging the sliding mechanism and the first driven guide rail mechanism 8 on the top of the box door 2 and the second driven guide rail mechanism 9 on the bottom of the box door 2, the top of the box 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 box 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 box door 2 is more stable and reliable.

[0268] 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.

[0269] 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.

[0270] Further, 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, forming 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, forming a third notch 1401. One end of the third connecting block 905 provided with a slot passes through the third notch 1401.

[0271] 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 aesthetically pleasing. 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 outside the first main decorative cover 13 through the first notch 1303 and the second notch 1304 respectively to connect with 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 aesthetically pleasing. The second driven guide rail mechanism 9 passes through the third notch 1401 and is used to connect with the door panel 21, so that the second driven guide rail mechanism 9 can cooperate to guide the door panel 21 to move relative to the door 2 during the opening or closing process of the door 2.

[0272] 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.

[0273] In one embodiment of the present application, as Figure 19 , Figure 23 and Figure 24 shown, one of the first main decorative cover 13 and the first end cover 210 is provided with a first protrusion, and the other is provided with a first groove corresponding to the first protrusion. The first main decorative cover 13 is detachably connected to the first end cover 210 through the first protrusion and the first groove.

The second main decorative cover 14 is detachably connected to the second end cover 220 through the second protrusion and the second groove.

[0275] In this embodiment, the first end cover 210 is provided with a first protrusion, and the first main decorative cover 13 is provided with a first groove. The first protrusion and the first groove can be engaged with each other to fix the first main decorative cover 13 and the first end cover 210 to each other.

[0276] It can be understood that the positions of the first protrusion and the first groove can be interchanged, that is, the first end cover 210 is provided with a first groove, and the first main decorative cover 13 is provided with a first protrusion.

[0277] Similarly, as Figure 20 , Figure 26 and Figure 27 shown, the second end cover 220 is provided with a second protrusion, and the second main decorative cover 14 is provided with a second groove. The second protrusion and the second groove can be engaged with each other to fix the second main decorative cover 14 and the second end cover 220 to each other.

[0278] 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 main decorative cover 14 is provided with a second protrusion.

[0279] In one embodiment of the present application, as Figure 22 , Figure 25 and Figure 28As shown, the door body assembly further includes: a first auxiliary decorative cover 17 and a second auxiliary decorative cover 18. The first auxiliary decorative cover 17 is detachably disposed on the first end cover 210 for shielding the sliding mechanism and the first driven guide rail mechanism 8; the second auxiliary decorative cover 18 is detachably disposed on the second end cover 220 for shielding the second driven guide rail mechanism 9.

[0280] In this embodiment, in some usage scenarios, when the door panel 2 does not need to be installed on the outside of the box door 2, the first main decorative cover 13 on the first end cover 210 can be replaced by the first auxiliary decorative cover 17, and the second main decorative cover 14 on the second end cover 220 can be replaced by the second auxiliary decorative cover 18 respectively, so as to shield the two driven guide rail mechanisms of the sliding mechanism, improve the visual consistency of the box door 2, make it more beautiful, and meet different usage requirements of users.

[0281] In some embodiments of the present application, in one embodiment of the present application, one of the first auxiliary decorative cover 17 and the first end cover 210 is provided with a first protrusion, and the other is provided with a first groove corresponding to the first protrusion. The first auxiliary decorative cover 17 is detachably connected to the first end cover 210 through the first protrusion and the first groove.

[0282] One of the second auxiliary decorative cover 18 and the second end cover 220 is provided with a second protrusion, and the other is provided with a second groove corresponding to the second protrusion. The second auxiliary decorative cover 18 is detachably connected to the second end cover 220 through the second protrusion and the second groove.

[0283] In this embodiment, the first end cover 210 is provided with a first protrusion, and the first auxiliary decorative cover 17 is provided with a first groove. The first protrusion and the first groove can be engaged with each other to fix the first auxiliary decorative cover 17 and the first end cover 210 to each other.

[0284] It can be understood that the positions of the first protrusion and the first groove can be interchanged, that is, the first end cover 210 is provided with a first groove, and the first auxiliary decorative cover 17 is provided with a first protrusion.

[0285] Similarly, the second end cover 220 is provided with a second protrusion, and the second auxiliary decorative cover 18 is provided with a second groove. The second protrusion and the second groove can be engaged with each other to fix the second auxiliary decorative cover 18 and the second end cover 220 to each other.

[0286] 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.

[0287] 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.

[0288] 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 the hand into the handle groove, facilitating the user to manually open or close the box door 2, with a simple structure and convenient operation.

[0289] It can be understood that as Figure 28 shown, when the door panel 21 does not need to be installed, the second driven guide mechanism 9 in the second installation groove can be removed. Correspondingly, the second auxiliary decorative cover 18 is provided with a concave handle portion 1801 at the position corresponding to the second installation groove, facilitating the user to manually open and close the box door 2.

[0290] 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.

[0291] 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 mechanisms through the first hook 2111 and the second hook 2112, thereby slidably connecting the door panel 21 to the box 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 the door panel 21 not prone to shaking.

[0292] 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 box 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 box door 2. This makes it easier for the user to align the slot with the first hook 2111 and the second hook 2112, and the installation is more convenient.

[0293] 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 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.

[0294] 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.

[0295] In an embodiment of the present application, the door body assembly and the box body 1 are configured to be disposed 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.

[0296] In this embodiment, the box body 1 is disposed 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.

[0297] When the box door 2 rotates outward to open, the sliding mechanism drives the door panel 21 to slide a preset distance in a direction 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 box door 2 being unable 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 in a direction close to 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 box door 2 being unable to be completely closed and affecting 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.

[0298] In another embodiment of the present application, the door body assembly and the box body 1 are configured to be disposed 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.

[0299] In this embodiment, the box body 1 is disposed 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.

[0300] 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 on the side close to the first hinge 4, resulting in the box door 2 being unable 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 on the side away from the first hinge 4, resulting in the box door 2 being unable to close completely and affecting 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. 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.

[0301] In an embodiment of another aspect of the present application, as Figure 1 and Figure 2 shown, a refrigeration device is provided, including: a box body 1 and a door body assembly provided in any of the above embodiments. Among them, the box body 1 forms a storage space, and the box door 2 is rotatably connected to the box body 1 and is adapted to open or close the storage space.

[0302] In this embodiment, the door body assembly includes: a box door 2, a door panel 21, and a sliding mechanism. The sliding mechanism is provided on the box door 2 and is configured to drive the door panel 21 to move relative to the width direction of the box door 2 during the opening or closing process of the box door 2.

[0303] By providing the door panel 21 on the box 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 set flush with the groove side wall or the 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.

[0304] At the same time, when the box door 2 rotates, the sliding mechanism can drive the door panel 21 to move relative to the box door 2 during the rotation process of the box door 2 to move as far as possible away from obstacles such as the wall or cabinet body on the side of the side door of the box body 1, so as to prevent these obstacles from blocking the door panel 21 and affecting the rotation of the box door 2, resulting in the box door 2 being unable to open or close normally.

[0305] The combination of the box door 2 and the door panel 21 enables the refrigeration device to avoid interference between the door panel 21 and surrounding objects during both opening and closing, greatly improving the usability. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the sliding mechanism enables the door panel 21 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0306] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, the refrigeration device 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.
