[0002] In today's society, the rapid progress of technology has greatly driven the transformation of home living styles. Among them, embedded furniture, as a design concept that combines aesthetics and functionality in one, is favored by the majority of consumers. Embedded furniture cleverly integrates appliances or storage spaces into the home environment, not only effectively saving space, but also significantly improving the overall coordination and aesthetics of the home. Taking an embedded refrigerator as an example, this design enables the refrigerator to be seamlessly embedded in the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, although the embedded refrigerator exhibits significant advantages in improving the aesthetics and space utilization of the home, it still has a problem that cannot be ignored in actual use: the door is prone to interference or collision with the cabinet side wall during opening, resulting in poor user experience of the embedded refrigerator.

[0100] In today's society, the rapid progress of technology has greatly driven the transformation of home living styles. Embedded furniture, as a design concept that combines aesthetics and functionality, is favored by the majority of consumers. Embedded furniture cleverly integrates appliances or storage space into the home environment, not only effectively saving space, but also significantly improving the overall coordination and aesthetics of the home. Taking embedded refrigerators as an example, this design allows the refrigerator to seamlessly integrate into the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, despite the significant advantages of embedded refrigerators in improving home aesthetics and space utilization, there is one problem that cannot be ignored in the actual use process: the door body is prone to interference or collision with the cabinet side wall during opening, resulting in poor user experience of the embedded refrigerator.

[0101] Specifically, when an embedded refrigerator (referred to as a refrigerator) simultaneously meets the user's demand for two different refrigerator use requirements of pure flat full embedding and full embedding, the refrigerator door body (referred to as the door body) after connecting with the cabinet door panel (referred to as the door panel) will cause the entire door body assembly to thicken, resulting in that after the refrigerator is pushed into the accommodating space of the cabinet, only relying on the original single-axis or double-axis structure hinge of the refrigerator, the door body assembly with the cabinet door will interfere with the cabinet during opening and closing, resulting in that it cannot be normally opened and used. Therefore, the present application proposes a door body assembly that can make the door body and the door panel relatively slide, so that during the opening of the door body assembly, the door panel can slide towards the opening side (i.e. the opening side), so that during the opening process, the hinge side still maintains the thickness of the door body itself, consistent with the opening door scene without the door panel. During the closing process, the door panel will move towards the hinge side to return to the state before opening; thereby realizing the refrigerator embedding installation requirement with and without the door panel.

[0102] In order to be aesthetically pleasing, the gap between the door panels of the same row of cabinets is usually in the range of 0mm-5mm, and thus there is a possibility of interference between the hinge side of the door panel and the cabinet panel.

[0103] Based on this, the application provides a door body assembly of an embedded refrigeration equipment (hereinafter referred to as a door body assembly), which can meet the requirement that no interference occurs on the hinge side of the door body.

[0104] According to the embodiments of the application, referring to Figure 1 and Figure 2 , the door body assembly includes a cabinet door 2 and a door panel 21. The cabinet door 2 is rotatably connected to a refrigeration cabinet 1, which is used to be embedded into an accommodating space formed by an installation body. The installation body generally refers to a cabinet in this case, 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 accommodating space, and the following description is taken as an example of the installation body being a cabinet. The door panel 21 is movably installed on the cabinet door 2, and the door panel 21 can move along the width direction of the cabinet door 2. The door panel 21 is adapted to move relative to the cabinet door 2 to the door opening side of the cabinet door 2 during opening of the cabinet door 2; the door panel 21 has a second interference site, that is, a point c in Figure 2 , and the second interference site is located at the outer corner of the hinge side of the door panel 21. Wherein, the side facing away from the refrigeration cabinet 1 is the "outer" side, and conversely, the side facing the refrigeration cabinet 1 is the "inner" side. Since Figure 2 is a top view, the second interference site is a point in Figure 2 , it can be understood that for the door body assembly, the second interference site is a vertical line. Wherein, if the outer corner of the hinge side of the door panel 21 is in the form of a circular arc, the second interference site is the point farthest from the hinge axis of the cabinet door 2 on the arc segment. When the cabinet door 2 is closed, the distance between the end surface of the hinge side of the door panel 21 and the side wall of the accommodating space corresponding thereto is δ2, and δ2 is greater than the movement distance λ of the second interference site along the width direction of the accommodating space before the second interference site leaves the accommodating space, λ is also the vertical distance of the second interference site moving towards the side wall of the corresponding accommodating space. Wherein, when the cabinet door 2 is in the closed position, the width direction of the cabinet door 2 is consistent with the width direction of the accommodating space. As the cabinet door 2 is opened, the width direction of the cabinet door 2 and the width direction of the accommodating space form an angle.

[0105] According to the embodiments of the application, the position of the door panel 21 most likely to interfere is determined as the second interference site, and the position of the second interference site on the door panel 21 is determined. On this basis, the conditions that need to be met for the second interference site not to interfere are determined, and the rules that need to be met between the initial gap (δ2) of the hinge side of the door body assembly and the movement of the door panel 21 are determined to ensure the normal use of the embedded refrigeration equipment.

[0106] On the basis of the above, under the premise of meeting the non-interference of the door body assembly, in order to ensure the aesthetics and safety of use of the embedded refrigeration equipment, as mentioned in the foregoing, the initial gaps δ1 and δ2 on both sides of the door panel 21 generally do not exceed 5 mm. The application embodiments further give the upper limit value of δ2.

[0107] According to the embodiments of the present application, the distance δ2 satisfies: δ2≤λmax.

[0108] λmax is the upper limit value of δ2, corresponding to the value of γ when Δθ is Δθcrit.

[0109] λmax is the value of λ when γ is zero and Δθ is Δθcrit, λ and Δs are negatively correlated, combined with Figure 2 and Figure 3 , γ is the vertical distance of the first interference site from the side wall of the corresponding accommodation space, λ is the vertical distance of the second interference site from the side wall of the corresponding accommodation space, Δθ is the angle of rotation during the opening of the cabinet door 2, and Δθcrit is the Δθ when the first interference site leaves the accommodation space, wherein, "when the first interference site leaves the accommodation space" corresponds to Figure 2 and Figure 3 C point and e point of the cabinet are flush, that is, the interference site c point is located on the horizontal line where e point is located. γ and Δs are positively correlated, and Δs is the distance of the door panel 21 from the opening side of the cabinet door 2 during the opening of the cabinet door 2.

[0110] In combination with Figure 2 and Figure 3 , λmax is the value of λ when γ is zero and Δθ is Δθcrit. When γ is zero, the initial gap δ1 of 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 cabinet panel, the corresponding λmax of the hinge side of the door panel 21 is the required maximum λmax.

[0111] In combination with Figure 2 and Figure 3 , the hinge axis of the cabinet door 2 corresponds to point o in the figure, l1 is the vertical distance from the hinge axis of the cabinet door 2 to the inner surface of the door panel 21, l2 is the vertical distance from the hinge axis of the cabinet door 2 to the end surface of the opening side of the door panel 21, l3 is the vertical distance from the hinge axis of the cabinet door 2 to the end surface of the hinge side of the door panel 21, h is the thickness of the door panel 21, and Δs is the distance of the door panel 21 from the cabinet door 2 during the opening of the cabinet door 2.

[0112] Figure 2 and Figure 3In this paper, the positional and angular relationships of the refrigeration equipment (refrigerator) when it is initially closed and when the door 2 is opened to any angle are simplified and annotated. Corners where interference may occur during the opening process are marked with black dots. The first interference point, c, is prone to interference with point e on the outer right side of the first cabinet panel 601. That is, point e is the critical point where point c escapes interference (leaves the storage space) during the opening and closing process. The second interference point, d, is the outer right corner of the door panel 21, which is the corner where the right end of the door panel 21 first interferes with the left end of the adjacent second cabinet panel 602 during the opening and closing process. As can be seen from the figure, in the initial position, on the left side of the hinge axis, the angle between the hypotenuse oc (where c and the hinge axis o are located) and the inner side of the door panel is θ0. The angle when the door 2 is opened to any position is... Δ θ, the hypotenuse oc at this position, distances l2 and l1 are represented by dashed lines; in the initial position, on the right side of the hinge axis, the hypotenuse between point d and the hinge axis is od, and the angle when the door 2 is opened to any position is... Δ At θ, the hypotenuse od at that position, the distances l1+h and l3 are represented by dashed lines; it can be seen from the figure that during the opening process of the cabinet door 2, if the cabinet panel does not move along the door 2 towards the opening side, as the opening angle increases, point d will soon interfere with the left end face of the second cabinet panel 602, causing the cabinet door 2 to be unable to open. Therefore, in order to avoid interference affecting the opening, during the opening process, when the door opening angle is Δθ, the corresponding door panel 21 needs to move a distance Δs towards the opening side.

[0113] According to the embodiments of this application, it can be understood that the larger l1, l3, and h are, the easier it is for the door panel 21 to interfere. Therefore, l1, l3, h, and δ2 are positively correlated. And δ2 is negatively correlated with the maximum Δs before the first interference position leaves the accommodating space.

[0114] According to an embodiment of this application, assuming that after the door panel 21 moves a distance Δs, the length of the side where point c is located and the hinge axis o is set as a, and the angle between it and the horizontal line in the figure is set as α. At this time, the length of the side where point d is located and the hinge axis o is set as b, and the angle between it and the horizontal line in the figure is set as β.

[0115] In one embodiment, the spacing δ2 satisfies: δ2 ≥ λ = b * cosβ - l3,

[0116] in,

[0117] Therefore, given that l1, l3, δ1, and Δs are determined, δ2 can be calculated.

[0118] According to an embodiment of this application, during the opening process of the cabinet door 2, the door panel 21 moves towards the opening side of the cabinet door 2, and the opening side of the door panel 21 is prone to interference with the cabinet. Based on this, the position on the opening side of the door panel 21 most prone to interference is determined as the first interference position. Specifically, the door panel 21 has a first interference position, which is located at the inner corner of the opening side of the door panel 21, corresponding to... Figure 2 Point c in the equation. Because... Figure 2 This is a top view; the first interference position starts from... Figure 2 From a distance, it appears as a single point. It can be understood that, for the door assembly, the first interference point is a vertical line. Specifically, if the inner corner of the opening side is rounded, the first interference point is the point on the rounded segment furthest from the hinge axis of the door 2.

[0119] When the door 2 is closed, the distance between the end face of the door panel 21 on the opening side and the corresponding side wall of the accommodating space is δ1. δ1 is greater than the distance γ that the first interference position moves along the width direction of the accommodating space before leaving it. γ is the vertical distance that the first interference position moves towards the side wall of the corresponding accommodating space. Here, "when the first interference position leaves the accommodating space" corresponds to... Figure 2 The case where point C in the middle is aligned with point e in the cabinet, that is, the case where the interference point C is located on the horizontal line where point e is located.

[0120] According to embodiments of this application, to ensure the aesthetics and safety of the embedded cooling device while maintaining the non-interference of the door components, embodiments of this application further provide an upper limit value for δ1. The spacing δ1 satisfies: δ1≤γmax.

[0121] γmax is the upper limit of δ1, corresponding to the value of γ when λ is zero and Δθ is Δθcrit.

[0122] Among them, combined Figure 2 and Figure 3 γ is the vertical distance the first interference position moves toward the side wall of the corresponding receiving space, λ is the vertical distance the second interference position moves toward the side wall of the corresponding receiving space, Δθ is the rotation angle of the door 2 during opening, and Δθ when the first interference position leaves the receiving space is Δθcrit, where "when the first interference position leaves the receiving space" corresponds to Figure 2 and Figure 3 The case where point C in the middle is aligned with point e in the cabinet, that is, the case where the interference point C is located on the horizontal line where point e is located. γ and Δs are positively correlated, where Δs is the distance that the door panel 21 moves relative to the opening side of the door 2 during the opening process of the cabinet door 2.

[0123] Wherein, λ is zero, which means that δ2 can be zero at this time, that is, the initial gap between the hinge side of the door plate 21 and the cabinet plate can be zero or infinitely close to zero. At this time, in order to ensure that the hinge side of the door plate 21 does not interfere with the cabinet plate, the γmax of the opening side of the door plate 21 corresponding to the door plate 21 is the required maximum γmax, and the maximum δ1 does not need to exceed γmax.

[0124] According to the embodiments of the present application, δ1 is positively related to l1, l3, h, and the maximum Δs before the first interference position leaves the containing space. Specifically, it can be understood that the greater the thickness h is, the more likely the door plate 21 is to interfere at this time. Therefore, the thickness h and δ1 are positively related. In addition, δ1 is positively related to the maximum Δs before the first interference position leaves the containing space, that is, when the first interference position leaves the containing space, the greater the moving distance Δs of the door plate 21 relative to the cabinet door 2, the greater the δ1 at this time, so as to prevent the door plate 21 from colliding with the first cabinet plate 601 during movement.

[0125] In one embodiment, δ1≥γ=a×cosα-l2.

[0126] Wherein,

[0127] As described above, Δθ is the angle of rotation during the opening of the cabinet door 2, and Δs is the distance moved by the door plate 21 relative to the opening side of the cabinet door 2 during the opening of the cabinet door 2.

[0128] Therefore, under the condition that l1 and l2 are determined, the relationship between δ1 and Δs can be obtained. Wherein, under the condition that Δs is determined, Δθcrit can be obtained, wherein Δθcrit is the value of Δθ when the first interference position leaves the containing space.

[0129] The above calculation formula of δ1 and δ2 does not constitute a limitation on δ1 and δ2, for example, the above calculation formula can also have a correction coefficient or a correction parameter. In addition, the above calculation formula is for the case where the hinge axis is determined. If the cabinet door 2 is installed by using a double-axis hinge or a movable hinge, the hinge axis will change with the opening of the cabinet door 2 at this time, and then the calculation formula of δ1 and δ2 also changes adaptively, and the moving distance of the hinge axis needs to be calculated in the formula. In addition, if there is an installation gap between the door plate 21 and the cabinet door 2, then h in the above calculation formula is the distance between the sliding surface of the door plate 21 and the outer surface of the door plate 21, and l1 is the distance from the hinge point of the cabinet door 2 to the sliding surface of the door plate 21.

[0130] According to the embodiments of the present application, δ1 = δ2, and γ = λ, and thus the initial gaps on both sides of the door panel 21 and the cabinet are equal, ensuring the aesthetics of the embedded refrigeration device. When δ1 = δ2, the respective values of γ and λ can be obtained. Of course, δ1 and δ2 can also be unequal, and γ and λ can also be unequal. When δ1 is larger, δ2 can be smaller, and similarly, when δ2 is smaller, δ2 can be larger.

[0131] According to the embodiments of the present application, δ1 and δ2 can be artificially controlled during the installation of the embedded refrigeration device. Of course, limiting components can also be provided on the door opening side and the hinge side of the embedded refrigeration device, respectively, to ensure that the initial gap between the door opening side of the door panel 21 and the cabinet is δ1, and the initial gap between the hinge side of the door panel 21 and the cabinet is δ2 during installation. Alternatively, auxiliary installation tools can be provided, which have sizes corresponding to the sizes of δ1 and δ2, respectively, and thus during installation, the initial gaps between the door panel 21 and the cabinet can be ensured to meet the above settings by the auxiliary installation tools.

[0132] According to the embodiments of the present application, the relative movement between the door panel 21 and the cabinet door 2 is determined by the sliding mechanism or the traction mechanism driving the sliding mechanism to move. In the case where the relative movement between the door panel 21 and the cabinet door 2 is determined by the sliding mechanism, once the sliding mechanism is determined, the movement amount Δs of the door panel 21 is determined, and thus the value range of δ1 and the value range of δ2 can be obtained from Δs.

[0133] Alternatively, according to the embodiments of the present application, when δ1 and the parameters of the door body assembly are determined, the functional relationship between δ2 and Δs can be determined, and thus δ2 can be determined based on the determined sliding mechanism or traction mechanism.

[0134] In combination Figure 2 and Figure 3 In addition, the distance between the end face of the hinge side of the door panel 21 and the side wall corresponding to the accommodation space is δ2, and the distance between the end face of the hinge side of the door panel and the side wall corresponding to the accommodation space is δ2 is 0.5mm-6mm. In this case, the installation requirements of the door body assembly can be met, ensuring the hidden installation of the refrigeration device, and at the same time, the opening process can ensure that the door body assembly does not interfere with the installation body, improving the user experience. In one embodiment, l1 is 5mm-50mm, l2 is 240mm-700mm, l3 is (300mm to 700mm)-l2, h is 10mm to 25mm, and δ2 is 0.5mm-6mm.

[0135] In addition, when the box door 2 is closed, the distance between the end face of the door panel 21 on the opening side and the side wall of the accommodating space corresponding thereto is δ1, and δ1 is 0.5 mm-6 mm. In one embodiment, l1 is 5 mm-50 mm, l2 is 240 mm-700 mm, l3 is (300 mm to 700 mm)-l2, h is 10 mm to 25 mm, and δ1 is 0.5 mm-6 mm.

[0136] 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 door panel on the opening side is l2, the vertical distance from the hinge axis of the box door to the end face of the door panel on the hinge side is l3, 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)-l2, and h is 10 mm to 25 mm. In this case, the overall size of the door body assembly is appropriate, the concealment of the refrigeration equipment can be easily ensured, and interference of the door body assembly can be prevented. Common values of l2 include 597 mm, 600 mm, 747 mm, 750 mm, 607 mm, and 610 mm. Common values of h include 16 mm, 18 mm, 20 mm, 22 mm, and 25 mm.

[0137] According to an embodiment of the present application, when the opening angle of the door body assembly increases by 0.5°, the change in the movement distance Δs is not more than 3 mm. That is, the movement of the door panel is as uniform as possible, sudden large-angle movement of the door panel is prevented, and the door panel is as concealed as possible, so that the user is prevented from being panicked by the movement of the door panel.

[0138] According to an embodiment of the present application, before the first interference site leaves the accommodating space, the movement distance Δs is not more than 5 mm. For example, the angle corresponding to the time when the first interference site leaves the accommodating space is 2°-5°. Because Δs is small during this process, interference between the door panel and the accommodating space can be avoided.

[0139] In one embodiment, when the opening angle Δθ of the door body assembly is 0.5°, the movement distance Δs is 0.3 mm to 0.5 mm, and when the opening angle of the door body assembly increases by 0.5°, the change in the movement distance Δs is not more than 3 mm.

[0140] According to an embodiment of the present application, the related parameters during the opening process of the door body assembly can refer to the following table:

[0141] Table 1

[0142] According to the embodiment of the present application, the positions on the door panel 21 where the interference is most likely to occur are determined as the first interference position and the second interference position respectively, and the positions of the first interference position and the second interference position on the door panel 21 are determined. On this basis, the conditions to be met for the first interference position not to interfere and the conditions to be met for the second interference position not to interfere are determined, and thus the rules to be met between the initial gaps (δ1 and δ2) on both sides of the door body assembly and the movement of the door panel 21 are determined to ensure the normal use of the embedded refrigeration equipment.

[0143] According to the embodiment of the present application, in the case where 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 and λ≤δ2.

[0144] According to the embodiment of the present application, in the case where the size of the door body assembly is limited to the size in Table 1 above, during the opening of the door panel assembly, the angle between the line connecting the first interference position and the hinge center of the cabinet door and the horizontal position is set as α, and the angle between the line connecting the second interference position and the hinge center of the cabinet door and the horizontal position is set as β, the angle α is between 2.4° and 21°, and the angle β is between 66° and 72°.

[0145] According to the embodiment of the present application, the sliding door mechanism 7 comprises a sliding mechanism and a traction mechanism.

[0146] According to one embodiment of the present application, referring to Figures 4 to 5 , the sliding mechanism comprises a first base 717, a first sliding block 714, a second sliding block 713 and a flexible cable 706. The first base 717 is formed with a first guide rail on one side and a second guide rail on the other side. The first sliding block 714 is slidably arranged on the first guide rail, and the traction mechanism is rotatably connected between the cabinet 1 and the first sliding block 717. The second sliding block 713 is slidably arranged on the second guide rail and is used to be connected with the door panel 21. The flexible cable 706 is connected with the first sliding block 714 and the second sliding block 713 at both ends. In the case where the first sliding block 714 moves on the first guide rail, the first sliding block 714 drives the second sliding block 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 cabinet door 2.

[0147] It can be understood that the sliding mechanism of the present embodiment can be arranged on the cabinet door 2, one of the first sliding block 714 and the second sliding block 713 is drivingly connected with the cabinet door 2 or the cabinet 1, and the other is slidingly connected with the door panel 21 arranged outside the cabinet door 2, so that when the cabinet door 2 rotates, the first sliding block 714 and the second sliding block 713 relatively slide to drive the door panel 21 to slide relative to the cabinet door 2, so that the door panel 21 can avoid the obstacles on both sides during the opening and closing of the cabinet door 2.

[0148] Specifically, taking the example of the first slider 714 being connected to the cabinet 1 through the traction mechanism and the second slider 713 being connected to the door panel 21, the first base 717 of the embodiment can be arranged on the cabinet door 2. The two 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 in turn drive the door panel 21 to slide relative to the cabinet door 2.

[0149] 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.

[0150] For example, in the process of opening the cabinet door 2 to the outside of the cabinet 1, the cabinet 1 drives the first slider 714 to slide towards 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. away from the first hinge 4) through the flexible cable 706, so as to avoid interference between the door panel 21 and the obstacle outside. In the process of closing the cabinet door 2 to the side of the cabinet 1, the cabinet 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. towards the first hinge 4) through the flexible cable 706, so as to avoid interference between the door panel 21 and the obstacle after closing.

[0151] It can be understood that the first slider 714 can also be connected to the door panel 21, and correspondingly, the second slider 713 is connected to the cabinet door 2 or the cabinet 1 through the traction mechanism, and the working process is the same as the above-mentioned embodiment, which will not be described here.

[0152] According to the sliding mechanism of the present application, first and second guide rails are arranged on both sides of the first base 717, and the first and second sliders 714 and 713 are slidably arranged on the first and second guide rails respectively. The first and second sliders 714 and 713 can slide synchronously along the guide rails under the transmission of the flexible cable 706, and the sliding directions are opposite. One of the first and second sliders 714 and 713 is connected to the cabinet door 2 or the cabinet 1 through the traction mechanism, and the other is connected to the door panel 21 arranged outside the cabinet door 2, so that when the cabinet door 2 rotates, the two sliders slide relative to each other to drive the door panel 21 to slide relative to the cabinet door 2, so that the door panel 21 can avoid obstacles on both sides during the opening and closing of the cabinet door 2.

[0153] It should be noted that in actual application, the design of the first and second sliders 714 and 713 can be flexible and varied to adapt 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.

[0154] From a material perspective, the first slider 714 and the second slider 713 can be selected to have high wear resistance, low friction coefficient, and good stability, such as metal alloy, engineering plastic, or special lubricating material. The selection of these materials aims to improve the durability of the slider, reduce wear and noise during sliding, and ensure smooth sliding.

[0155] 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, etc. These different contact methods have their own advantages and disadvantages, for example, ball contact can reduce friction and wear, but the cost is higher; while plane contact is simple in structure, but may require more frequent lubrication and maintenance. Therefore, factors such as use conditions, cost-effectiveness, and maintenance convenience should be considered when selecting.

[0156] In addition, in order to enhance the carrying capacity and stability of the slider, reinforcing ribs, support plates or other auxiliary structures can 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.

[0157] 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, which can effectively reduce the size of the first base 717 in the height direction and the thickness direction 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, and the structure is more compact and occupies less space.

[0158] In actual application, due to factors such as machine tool precision, tool wear, material unevenness, etc., 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, 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 smooth sliding of the slider and stable operation of the system. This tolerance range is usually determined according to design requirements, use environment and system precision.

[0159] It should be noted that in this embodiment, parallel and vertical should not be strictly geometrically, at least manufacturing and installation errors should be considered, and positive and negative 10° errors should be understood as the scope protected by the patent.

[0160] In an embodiment of the present application, as Figure 5As shown, the flexible cable 706 includes a first flexible cable and a second flexible cable. The first flexible cable passes around one end of the first base 717 and is connected to one end of the first slider 714 and the second slider 713, respectively. The second flexible cable passes around the other end of the first base 717 and is connected to the other end of the first slider 714 and the second slider 713, respectively.

[0161] In this embodiment, by connecting the first flexible cable around 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 the one end of the first base 717 under the drive of the cabinet door 2 or the cabinet 1 through the traction mechanism, the first slider 714 drives the second slider 713 to slide towards the one end of the first base 717 through the first flexible cable. At the same time, by connecting the second flexible cable around 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 cabinet 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, the second slider 713 can be driven to slide in the opposite direction of the first slider 714, and the door panel 21 can slide relative to the cabinet door 2 when the cabinet door 2 is opened or closed, so as to avoid interference with obstacles and affect the opening and closing of the cabinet door 2.

[0162] The flexible cable 706 is one of a steel wire rope, a steel strand, or a hemp rope. It is selected according to the required load bearing, working environment, and use requirements. For occasions that require bearing large load and harsh environment, it is recommended to select a steel wire rope or a steel strand; for occasions with smaller load and moderate environment, a hemp rope can be considered. Under the premise of meeting the use requirements, the cost difference of different materials is considered, and the material with high cost performance is selected. In addition, the steel wire rope and the steel strand may need to be regularly inspected and maintained during use to ensure their performance and safety; while the hemp rope is relatively easy to replace and maintain.

[0163] Specifically, the second slider 713 and the first slider 714 are both provided with a connecting head 711 for fixing the flexible cable 706.

[0164] In one embodiment of the present application, as Figure 5As shown, the sliding mechanism further comprises 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 and is formed with a first limiting slot. The two ends of the first limiting slot are in abutment with one end of the first guide rail and the second guide rail. A portion of the first flexible cable is slidably arranged in the first limiting slot. The second fixed seat 702 is connected to the other end of the first base 717 and is formed with a second limiting slot. The two ends of the second limiting slot are in abutment with the other end of the first guide rail and the second guide rail. A portion of the second flexible cable is slidably arranged in the second limiting slot.

[0165] In the embodiment, by arranging the first fixed seat 701 and the second fixed seat 702 at the two ends of the first base 717, the first fixed seat 701 and the second fixed seat 702 are respectively formed with the first limiting slot and the second limiting slot in abutment 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, so that the sliding of the first flexible cable and the second flexible cable is smoother.

[0166] Specifically, the first fixed seat 701 is provided with a first fixed 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 comprises a first adjusting member 704. The first adjusting member 704 passes through the first fixed hole and is slidably arranged in the first waist-shaped hole. The tightness of the first flexible cable is adjusted by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0167] In the 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 along the width direction of the first base 717 is adjusted. The first fixed seat 701 can tighten or loosen the first flexible cable, so as to adjust the tightness of the first flexible cable.

[0168] Since the first flexible cable and the second flexible cable are respectively arranged on the first fixed seat 701 and the second fixed seat 702 at the two sides of the first base 717, and the first flexible cable and the second flexible cable are connected to the two ends of the first sliding block 714 and the second sliding block 713, when the first fixed seat 701 is adjusted relative to the first base 717 through the first waist-shaped hole, the tightness of the first flexible cable is adjusted, and the tightness of the second flexible cable is also adjusted under the pulling of the first fixed seat 701 on the first flexible cable.

[0169] It can be understood that the first fixed hole can also be arranged on the second fixed seat 702. The first base 717 is provided with a first waist-shaped hole extending along the width direction of the first base 717. The sliding mechanism further comprises a first adjusting member 704. The first adjusting member 704 passes through the first fixed hole and is slidably arranged in the first waist-shaped hole. The tightness of the second flexible cable is adjusted by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0170] In the embodiment, the position of the second fixed seat 702 along the width direction of the first base 717 can be adjusted by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, so that the second fixed seat 702 can tighten or loosen the second flexible cable, thereby adjusting the tightness of the second flexible cable.

[0171] Since the first flexible cable and the second flexible cable are respectively located on the first fixed seat 701 and the second fixed 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 the second fixed seat 702 is adjusted relative to the first base 717 through the first waist-shaped hole, the tightness of the second flexible cable is adjusted, and the tightness of the first flexible cable is also adjusted under the pulling of the second fixed seat 702 to the second flexible cable.

[0172] Further, in some embodiments, the first fixed seat 701 is provided with a second waist-shaped hole extending along the width direction of the first base 717. The first base 717 is provided with a second fixed hole. The sliding mechanism further includes a second adjusting member 703, which is fixed in the external structure in sequence through the second waist-shaped hole and the second fixed hole, so as to adjust the position of the first fixed seat 701 relative to the external structure by the position of the second adjusting member 703 in the second waist-shaped hole.

[0173] In the embodiment, the first fixed seat 701 is fixed in the external structure by providing the second waist-shaped hole on the first fixed seat 701 and fixing the second adjusting member 703 in the external structure in sequence through the second waist-shaped hole and the second fixed hole, 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 fixed seat 701, thereby being able to adjust the position of the first fixed seat 701 relative to the external structure.

[0174] It can be understood that the second fixed seat 702 can also be provided with a second waist-shaped hole extending along the width direction of the first base 717; the second adjusting member 703 is fixed in the external structure in sequence through the second waist-shaped hole and the second fixed hole, so as to adjust the position of the second fixed seat 702 relative to the external structure by 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 fixed hole are similar to those of the above-mentioned embodiments, which will not be described here.

[0175] Further, in some embodiments, a rotatable support bearing is arranged in the first limiting slot; a portion of the first flexible cable abuts against the support bearing in the first limiting slot. In this embodiment, by abutting a portion of the first flexible cable against the support bearing, the extension direction of the first flexible cable is adjusted, and the first flexible cable is conveniently routed around the end of the first base 717 to be connected with the first slider 714 and the second slider 713.

[0176] It can be understood that a rotatable support bearing can also be arranged in the second limiting slot; a portion of the second flexible cable abuts against the support bearing in the second limiting slot, so as to adjust the extension direction of the second flexible cable, and the second flexible cable is conveniently routed around the end of the first base 717 to be connected with the first slider 714 and the second slider 713.

[0177] Specifically, in some embodiments, the support bearing includes a first bearing 705 and a second bearing 716, which are respectively arranged at one end of the same side of the first guide rail and the second guide rail, and are respectively arranged at two sides of the first base 717.

[0178] In an embodiment of the present application, as shown in Figure 5 the traction mechanism includes a traction rod 709, a first rotating shaft fixing seat 707, and a second rotating shaft fixing seat 710. The first rotating shaft fixing seat 707 is connected to the first slider 714, and the second rotating shaft fixing seat 710 is used to be connected to the cabinet 1. One end of the traction rod 709 is rotatably connected to the first rotating shaft fixing seat 707, and the other end of the traction rod 709 is rotatably connected to the second rotating shaft fixing seat 710.

[0179] 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 cabinet 1 respectively, and connecting them through the traction rod 709, the distance between the first slider 714 and the second rotating shaft fixing seat 710 is always kept unchanged. When the cabinet door 2 rotates relative to the cabinet 1, the angle between the cabinet 1 and the cabinet door 2 changes, thereby driving the first slider 714 through the transmission connection of the traction rod 709, the first rotating shaft fixing seat 707, and the second rotating shaft fixing seat 710, so that the first slider 714 slides on the first base 717, and the second slider 713 is driven to slide to realize the movement of the door panel 21 relative to the cabinet door 2.

[0180] 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.

[0181] In another aspect of an embodiment of the present application, as shown in Figure 1 andFigure 4 As shown, a door assembly is provided, including: a door 2, a door panel 21, and a sliding mechanism as provided in any of the above embodiments. The door 2 is rotatably connected to a housing 1 and is adapted to open or close the storage space of the housing 1. The door panel 21 is slidably disposed on the outside of the door 2; the sliding mechanism is disposed on the door 2, a first slider 714 is used for transmission connection with the housing 1, and a second slider 713 is connected to the door panel 21. During the opening or closing 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.

[0182] Specifically, during the process of the door 2 rotating outwards to open the box body 1, the first slider 714 slides towards the first hinge 4 under the drive of the box body 1 via the traction mechanism. The first slider 714 drives the second slider 713 to slide away from the first hinge 4 via the flexible cable 706, thereby driving the door panel 21 to slide away from the first hinge 4, thus preventing the door panel 21 from interfering with obstacles on the outside. Similarly, during the process of the door 2 rotating towards the box body 1 to close, the sliding mechanism drives the door panel 21 to slide towards the first hinge 4, thereby preventing the closed door panel 21 from interfering with obstacles.

[0183] According to the door assembly of the present application embodiment, a sliding mechanism is provided on the door 2. The sliding mechanism is connected to the door 2 and the door panel 21 respectively, so that when the door 2 rotates to open or close relative to the box body 1, the door panel 21 is driven to slide relative to the width direction of the door 2, so that the door panel 21 can avoid obstacles such as side walls and objects when the door 2 is closed or opened.

[0184] It is understood that since the sliding mechanism has the beneficial effects of the above embodiments, the door assembly will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.

[0185] In one embodiment of this application, such as Figures 5 to 6 As shown, the second slider 713 is provided with a first connecting block 712, and the first connecting block 712 has a slot for the door panel 21 to be hung.

[0186] In this embodiment, a first connecting block 712 is provided on the second slider 713, and a slot is provided on the first connecting block 712. Correspondingly, the door panel 21 is provided with a connecting component (such as a hook, plug, etc.) adapted to the slot, so that the door panel 21 can be installed on the first connecting block 712 and the door panel 21 can slide with the second slider 713. At the same time, it is also convenient for the user to remove the door panel 21 from the second slider 713 when needed, meeting the user's usage needs in different scenarios.

[0187] According to another embodiment of the present application, in addition to the above structure of double guide rails and double sliding blocks, the sliding mechanism of the present application can also adopt the structure in Figures 8 to 10 . The sliding mechanism includes a guide member 730, a sliding member 740, a linkage assembly 750, and a driving rod 760.

[0188] The guide member 730 is configured to be provided on the cabinet door, and the guide member 730 is provided with a guide structure 731. 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.

[0189] The linkage assembly 750 is movably provided on the guide structure 731 and can deform in structure under the guidance of the guide structure 731. The second end of the linkage assembly 750 is movably connected with the sliding member 740.

[0190] The driving rod 760 is provided on the cabinet and movably connected with the first end of the linkage assembly 750, so as to drive the linkage assembly 750 to deform in structure during the opening and closing of the cabinet door, and then drive the sliding member 740 to move the door panel along the width direction by the linkage assembly 750.

[0191] It can be understood that, as shown in the figure, the cabinet is provided with a hinge, the hinge is provided with a hinge shaft, and the cabinet door is movably provided on the hinge shaft, so as to realize the opening or closing of the cabinet door relative to the cabinet.

[0192] The guide structure 731 can ensure that the linkage assembly 750 moves along a predetermined path or direction, prevent it from deviating from the predetermined trajectory, and guide the deformation of the linkage assembly 750, and then drive the sliding member 740 to move along the width direction of the cabinet door.

[0193] Optionally, the guide structure 731 can guide the linkage assembly 750 to move along the tooth shape of the chain wheel through the cooperation of the chain wheel and the chain. The guide structure 731 can also guide the linkage assembly 750 to move along the section of the guide rail through the cooperation of the sliding block 742 and the guide rail.

[0194] The linkage assembly 750 deforms in structure, so that the distance between the second end of the linkage assembly 750 and the hinge changes, and then the distance between the sliding member 740 and the hinge changes, and further realizes the change of the distance between the door panel connected with the sliding member 740 and the hinge.

[0195] Optionally, the linkage assembly 750 can be a parallel four-bar linkage mechanism, or a crank rocker mechanism.

[0196] For the sliding mechanism shown in the embodiment, the guide 730 is arranged on the cabinet door, the sliding member 740 is arranged on the door panel, the sliding member 740 is movably arranged on the guide 730 along the width direction of the cabinet door, the guide structure 731 is arranged on the guide 730, the guide structure 731 can guide the structural deformation of the link assembly 750, and the second end of the link assembly 750 is movably connected with the sliding member 740. When the cabinet door is opened, the driving rod 760 drives the first end of the link assembly 750, the link assembly 750 deforms in structure, the second end of the link assembly 750 pulls the sliding member 740 to move towards the direction away from the hinge, and then drives the door panel to move towards the direction away from the hinge along the width direction of the cabinet door, so that the door panel is prevented from interfering with the cabinet body; when the cabinet door is closed, the driving rod 760 drives the first end of the link assembly 750, the link assembly 750 deforms in structure, the second end of the link assembly 750 pulls the sliding member 740 to move towards the direction close to the hinge, and then drives the door panel to move towards the direction close to the hinge along the width direction of the cabinet door, so that the door panel is restored to the original position, and interference between the door panel and the cabinet body around the refrigeration equipment is prevented.

[0197] In some embodiments, as shown in Figure 8 The link assembly 750 includes a first link 751 and a second link 752.

[0198] The driving rod 760 is rotatably connected with the first end of the first link 751, the second end of the first link 751 and the first end of the second link 752 are rotatably connected through a first hinge shaft 753; the first hinge shaft 753 is arranged on the guide structure 731 and moves along the thickness direction of the door panel under the guidance of the guide structure 731; the second end of the second link 752 is rotatably connected with the sliding member 740.

[0199] The driving rod 760 is used to drive the first end of the first link 751 to move along the width direction, the first link 751 is used to drive the first hinge shaft 753 to move along the thickness direction, so as to change the included angle between the first link 751 and the second link 752, and then the second link 752 drives the sliding member 740 to move in the direction opposite to the driving direction of the driving rod 760.

[0200] It can be understood that the driving rod 760 provides a driving force to the first end of the first link 751, the guide structure 731 can constrain the movement path of the first hinge shaft 753, so that the first hinge shaft 753 can only move along the thickness direction of the cabinet door, thereby changing the included angle between the first link 751 and the second link 752, so that the second link 752 moves along the width direction.

[0201] During the opening of the cabinet door, the drive rod 760 drives the first end of the first link 751 to move along the width direction toward the hinge. The first link 751 drives the first hinge shaft 753 to move along the thickness direction toward the sliding member 740, making the included angle between the first link 751 and the second link 752 larger. This pushes the second link 752 to move away from the hinge, thereby driving the sliding member 740 to move along the width direction away from the hinge, so that the door panel and the side cabinet do not interfere with each other.

[0202] During the closing process of the cabinet door, the drive rod 760 drives the first end of the first link 751 to move away from the hinge along the width direction. The first link 751 drives the first hinge shaft 753 to move away from the sliding member 740 along the thickness direction, making the included angle between the first link 751 and the second link 752 smaller. This pushes the second link 752 to move closer to the hinge, thereby driving the sliding member 740 to move closer to the hinge along the width direction, so that the door panel returns to its original position, ensuring that the door panel does not interfere with the cabinets around the refrigeration equipment.

[0203] This embodiment uses a first connecting rod 751, a second connecting rod 752, and a first hinge shaft 753 in the connecting rod assembly 750. By limiting the movement of the first hinge shaft 753 in the thickness direction, the angle between the first connecting rod 751 and the second connecting rod 752 is changed, allowing the second connecting rod 752 to drive the sliding member 740 to move in the width direction, thus realizing the movement of the door panel relative to the cabinet door. The structure is simple and the size is small.

[0204] In some embodiments, such as Figure 8 As shown, the drive rod 760 includes a linkage.

[0205] The first end of the linkage is configured to be rotatably fixed on the cabinet of the refrigeration equipment, and the second end of the linkage is rotatably connected to the first end of the first link 751; the fixed position is offset from the hinge position between the door and the cabinet.

[0206] During the process of opening the cabinet door, the linkage is used to drive the first end of the first linkage 751 to move toward the side closer to the hinge position, and the second linkage 752 drives the sliding member 740 to move the door panel toward the side away from the hinge position.

[0207] During the process of closing the cabinet door, the linkage is used to drive the first end of the first linkage 751 to move away from the hinge position, and the second linkage 752 drives the sliding member 740 to move the door panel towards the hinge position.

[0208] It can be understood that the first end of the linkage member in the embodiment is rotatably arranged on the hinge, and when the cabinet door rotates relative to the cabinet body around the hinge shaft, the second end of the linkage member rotates around the hinge shaft as the center. Since the first end of the linkage member is arranged in a staggered manner with the hinge shaft, the distance between the second end of the linkage member and the hinge changes with the rotation of the linkage member, thereby driving the linkage assembly 750 to move towards or away from the hinge along the width direction of the cabinet door.

[0209] In the process of opening the cabinet body by the cabinet door, with the rotation of the cabinet door, the cabinet door drives the linkage member to rotate, the second end of the linkage member drives the first end of the first linkage rod 751 to move towards the side close to the hinge position, the second end of the second linkage rod 752 drives the sliding member 740 to move towards the side away from the hinge position, thereby making the door panel move towards the side away from the hinge position.

[0210] In the process of closing the cabinet body by the cabinet door, with the rotation of the cabinet door, the cabinet door drives the linkage member to rotate, the second end of the linkage member drives the first end of the first linkage rod 751 to move towards the side away from the hinge position, the second end of the second linkage rod 752 drives the sliding member 740 to move towards the side away from the hinge position, thereby making the door panel move towards the side close to the hinge position.

[0211] In the embodiment, the first end of the linkage member is arranged to deviate from the hinge position between the cabinet door and the cabinet body, so that the second end of the linkage member can drive the first end of the first linkage rod 751, and the second linkage rod 752 can drive the sliding member 740 to move along the width direction. The opening and closing of the cabinet door can control the transmission of the linkage assembly 750 driven by the linkage member, and the sliding member 740 can drive the door panel to move along the width direction. Without additional driving devices, the movement of the door panel relative to the cabinet door can be synchronized with the opening and closing of the cabinet door.

[0212] In some embodiments, as shown in FIG. 7A, the guiding structure 731 includes a first limiting slot 7311. Figure 9

[0213] The first limiting slot 7311 extends along the thickness direction.

[0214] The first hinge shaft 753 is inserted into the first limiting slot 7311 and can move along the extension direction of the first limiting slot 7311.

[0215] It can be understood that the first limiting slot 7311 is used to limit the first hinge shaft 753, so that the first hinge shaft 753 can only move along the thickness direction, thereby changing the included angle between the first linkage rod 751 and the second linkage rod 752 connected with the first hinge shaft 753 respectively, and the moving direction of the second end of the first linkage rod 751 is opposite to that of the second end of the second linkage rod 752.

[0216] ​The first limiting groove 7311 can guide the moving direction of the first hinged shaft 753, and the first limiting groove 7311 can be directly arranged on the upper surface of the guide piece 730, without occupying additional space, thereby ensuring the compactness of the structure of the sliding mechanism.

[0217] In some embodiments, as shown in Figure 9 The guide structure 731 further includes a second limiting groove 7312.

[0218] The second limiting groove 7312 extends along the width direction and is in communication with the first limiting groove 7311.

[0219] The driving rod 760 is rotationally connected with the first end of the first connecting rod 751 through a second hinged shaft 754, and the second end of the second connecting rod 752 is rotationally connected with the sliding piece 740 through a third hinged shaft 755; the second hinged shaft 754 and the third hinged shaft 755 are respectively inserted into the second limiting groove 7312 and can move along the extension direction of the second limiting groove 7312.

[0220] The second hinged shaft 754 and the third hinged shaft 755 are respectively arranged on the two sides of the first limiting groove 7311.

[0221] It can be understood that the second limiting groove 7312 is used for limiting the second hinged shaft 754 and the third hinged shaft 755, so that the second hinged shaft 754 and the third hinged shaft 755 can only move along the width direction, thereby enabling the second connecting rod 752 to drive the sliding piece 740 to move along the width direction. The second limiting groove 7312 of the present embodiment ensures that the moving direction of the sliding piece 740 will not deviate, thereby ensuring the reliability and stability of the moving direction of the sliding piece 740, and further ensuring the reliability of the door panel moving along the width direction of the cabinet door.

[0222] In some embodiments, as shown in Figure 8 The sliding mechanism further includes an elastic piece 770.

[0223] The elastic piece 770 is arranged between the guide piece 730 and the sliding piece 740.

[0224] When the connecting rod assembly 750 drives the sliding piece 740 to move towards the side away from the hinged position, the sliding piece 740 compresses the elastic piece 770 in the process of driving the door panel to move.

[0225] When the connecting rod assembly 750 drives the sliding piece 740 to move towards the side close to the hinged position, the elastic piece 770 drives the sliding piece 740 to drive the door panel to move towards the hinged position.

[0226] The hinged position is located between the cabinet door and the cabinet body, and the cabinet door is rotationally arranged on the cabinet body based on the hinged position.

[0227] It can be understood that when the linkage assembly 750 drives the sliding piece 740 to move towards the side away from the hinge position, the elastic piece 770 is extruded in the direction away from the hinge to accumulate elastic potential energy.

[0228] When the linkage assembly 750 drives the sliding piece 740 to move towards the side close to the hinge position, the elastic potential energy of the elastic piece 770 is released, and the elastic force of the elastic piece 770 acts on the sliding piece 740 to drive the sliding piece 740 to move close to the hinge position.

[0229] Specifically, the elastic piece 770 can be an elastic sheet, an elastic block, or a spring.

[0230] The embodiment can ensure that the movement of the sliding piece 740 relative to the guide piece 730 is more stable and reliable based on the elastic deformation of the elastic piece 770 by arranging the elastic piece 770 on the sliding mechanism.

[0231] In some embodiments, as shown in Figures 8 to 10 The guide piece 730 includes a fixed plate 732 and a sliding groove 733.

[0232] The fixed plate 732 is configured to be arranged on the cabinet door.

[0233] The sliding groove 733 is arranged on the fixed plate 732 and extends in the width direction, and at least part of the sliding piece 740 is movably arranged in the sliding groove 733 in the width direction.

[0234] It can be understood that the fixed plate 732 of the embodiment is used to be fixedly connected with the cabinet door, the sliding groove 733 is used to guide the movement of the sliding piece 740 in the width direction of the cabinet door, and based on the sliding cooperation between the sliding piece 740 and the sliding groove 733, it can be ensured that the sliding piece 740 can stably and reliably move in the width direction of the cabinet door.

[0235] In some embodiments, as shown in Figure 9 and Figure 10 The guide piece 730 further includes a sliding sleeve 734, and the sliding sleeve 734 is arranged at one end of the sliding groove 733 away from the hinge position.

[0236] The sliding piece 740 includes a guide rod 741 and a sliding block 742, the guide rod 741 is arranged in the sliding sleeve 734, the guide rod 741 is provided with a sliding contact 745, and the sliding contact 745 is movably arranged in the sliding groove 733 in the width direction; the sliding block 742 is connected with the guide rod 741 and is configured to be connected with the door plate.

[0237] The elastic piece 770 is arranged between the sliding sleeve 734 and the sliding contact 745.

[0238] It can be understood that the sliding groove 733 of the embodiment is arranged in an arc shape to match 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 sliding groove 733, and with the movement of the sliding piece 740 on the sliding groove 733, the sliding contact 745 also moves, the sliding sleeve 734 is fixedly arranged relative to the fixed plate 732, the elastic piece 770 is limited between the sliding sleeve 734 and the sliding contact 745, when the guide rod 741 moves towards the side away from the hinge, the sliding contact 745 moves towards the sliding sleeve 734, causing the elastic piece 770 between the sliding sleeve 734 and the sliding contact 745 to be compressed, when the guide rod 741 moves towards the side close to the hinge, the elastic piece 770 releases the elastic potential energy and elongates, the sliding contact 745 moves in the direction away from the sliding sleeve 734, and the sliding sleeve 734 and the sliding contact 745 constrain the elastic piece 770 from both sides to ensure the reliability of the compression and elongation of the elastic piece 770.

[0239] Furthermore, one end of the sliding block 742 is connected with the guide rod 741, and the other end is connected with the door plate, so that when the guide rod 741 moves along the width direction of the cabinet door, the sliding block can drive the door plate to move along the width direction of the cabinet door.

[0240] In some embodiments, as shown in Figure 8 The elastic piece 770 includes a spring, which is sleeved on the outer side of the guide rod 741 and is limited between the sliding sleeve 734 and the sliding contact 745.

[0241] It can be understood that when the elastic piece 770 is a spring, the hollow structure of the spring allows 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 spring changes between the compressed and elongated states, and the sliding sleeve 734 and the sliding contact 745 can limit the two sides of the spring from both ends of the guide rod 741, facilitating the stopping of both ends during compression and elongation of the spring. The spring of the embodiment makes the structure simple and compact when the door plate is reset relative to the cabinet door, has a small volume, and saves the installation space of the door plate.

[0242] In some embodiments, as shown in Figure 8 and Figure 9 The sliding piece 740 further includes a first connecting arm 743 and a second connecting arm 744.

[0243] The first connecting arm 743 and the second connecting arm 744 are arranged in the width direction and are spaced apart, the first end of the guide rod 741 is connected with 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 with the second end of the sliding block 742 through the second connecting arm 744.

[0244] The sliding sleeve 734 and the sliding contact 745 are located between the first connecting arm 743 and the second connecting arm 744.

[0245] 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 from both ends of the guide rod 741 and the sliding block 742, so that the connection of the guide rod 741 and the sliding block 742 is more firm, and the sliding block 742 is more easily attached when moving along the width direction of the cabinet door.

[0246] Further, the sliding block 742 of the embodiment is vertically arranged with the first connecting arm 743 and the second connecting arm 744, so that when the door panel is installed on the sliding block 742, the fixed plate 732 is installed at the top end of the cabinet door, and the door panel and the cabinet door can be attached in parallel, ensuring the flatness of the door panel installed on the cabinet door, and facilitating the movement of the door panel along the cabinet door.

[0247] Of course, in addition to the above slide rail and block form or connecting rod form, the sliding mechanism can also adopt a gear and rack form or a cable structure form, and the specific structure is not limited, as long as the sliding mechanism can drive the door panel to move relative to the cabinet door. Correspondingly, the traction mechanism is not limited by the above examples, for example, the traction mechanism can adopt a cylinder, a rope and the like, and specific examples are not given one by one. In addition, the traction mechanism can be an electric structure or a mechanical structure.

[0248] In an embodiment of the present application, Figure 4 、 Figure 11 and Figure 12 As shown in the figure, the door body assembly further comprises a first driven guide rail mechanism 8.

The third sliding block 813 is provided with a second connecting block 812, and the second connecting block 812 is formed with a slot for hanging the door panel 21.

The third sliding block 813 can slide with the door panel 21 when the door panel 21 slides relative to the cabinet door 2, which supports and assists the sliding of the door panel 21, making the door panel 21 slide more smoothly relative to the cabinet door 2. At the same time, the first driven guide rail mechanism 8 can limit the movement direction of the door panel 21 in cooperation with the sliding mechanism, reducing the shaking of the door panel 21 during sliding, and making the sliding more stable. In addition, the slot on the second connecting block 812 can facilitate the user to install the door panel 21 on the driven guide rail mechanism.

[0250] Further, the first driven guide rail mechanism 8 further comprises a third fixed seat 801 and a fourth fixed seat 802, which are also provided with limiting grooves similar to the first fixed seat 701 and the second fixed seat 702.

[0252] It can be understood that the fourth fixed seat 802 can also be provided with a third fixed hole; the second base 817 is provided with a third waist-shaped hole extending along the width direction of the second base 817; the third adjusting part 804 passes through the third fixed hole and is slidably arranged in the third waist-shaped hole to adjust the position of the third adjusting part 804 in the third waist-shaped hole.

[0253] Further, the third fixed seat 801 is provided with a fourth waist-shaped hole extending along the width direction of the second base 817. The second base 817 is provided with a fourth fixed hole.
