[0002] In today's society, the rapid progress of science and technology has greatly promoted the transformation of home lifestyles. Among them, built-in furniture, as a design concept that combines beauty and practicality, is favored by consumers. By cleverly integrating electrical appliances or storage space 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 allows 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 built-in refrigerator has shown significant advantages in improving home aesthetics and space utilization, there is still a problem that cannot be ignored in its actual use: the door is prone to interfere or collide with the side wall of the cabinet during opening, resulting in a poor user experience of the built-in refrigerator.

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

[0099] In today's society, the rapid progress of science and technology has greatly promoted the transformation of home lifestyles. Among them, built-in furniture, as a design concept that combines beauty and practicality, is favored by consumers. By cleverly integrating electrical appliances or storage space 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 allows 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 built-in refrigerator has shown significant advantages in improving home aesthetics and space utilization, there is still a problem that cannot be ignored in its actual use: the door is prone to interfere or collide with the side wall of the cabinet during opening, resulting in a poor user experience of the built-in refrigerator.

[0100] Specifically, when the built-in refrigerator (referring to refrigerator) satisfies the user's requirements for two different types of refrigerators, namely, pure flat and fully embedded, the entire door assembly will be thickened after the refrigerator door body (referred to as box door) is connected to the cabinet door panel (referred to as door panel). As a result, after the refrigerator is pushed into the storage space of the cabinet, the door assembly with the cabinet door will interfere with the cabinet during the process of opening and closing the door, relying only on the original single-axis or double-axis structural hinges of the refrigerator, resulting in the inability to open and use the door normally. Therefore, a door assembly is required that can enable the box door and the door panel to slide relative to each other, so that in the process of opening the door assembly, the door panel can slide toward the side of the door opening (that is, the door opening side), so that in the process of opening the door, the hinge side still maintains the thickness of the box door itself, which is consistent with the door opening scene without a door panel; in the process of closing the door, the door panel will move toward the hinge side to return to the state before the door is opened; thereby achieving the embedded installation requirements of the refrigerator with or without a door panel.

[0101] The above door body assembly with a door panel that can move relative to the cabinet door is prone to interfere with the cabinet because the door panel faces the opening side of the cabinet door. Based on this, the present application provides a door body assembly of an embedded refrigeration device (hereinafter referred to as the door body assembly), during which the gap between the door opening side of the door panel and the interference object meets a certain rule to prevent the door panel from interfering.

[0102] See also Figure 1, the door assembly includes a door 2 and a door panel 21. The door 2 can be rotatably connected to the refrigeration body 1, and the refrigeration body 1 is used to be embedded in the accommodating space formed by the installation body. The installation body here 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 the accommodating space can be formed, the following description will take the installation body as the cabinet 60 as an example. The door panel 21 is movably mounted on the door 2, and the door panel 21 can move along the width direction of the door 2; the door panel 21 is suitable for moving relative to the door 2 toward the opening side of the door 2 during the opening of the door 2. Combined with Figure 2 and Figure 3 , the door panel 21 has a first interference position c, which is located at the inner corner of the door opening side of the door panel 21. The "inside" and "outside" are relative to the refrigeration box 1, the side facing the refrigeration box 1 is the "inside" side, and the side facing away from the refrigeration box 1 is the "outside" side. Figure 2 The first interference position is from Figure 2 It is a point in the middle. It can be understood that for the door body assembly, the first interference position is a vertical line. If the inner corner of the door opening side is in an arc shape, the first interference position at this time is the point on the arc segment farthest from the hinge axis of the door 2.

[0103] Combination Figure 2 and Figure 3 , when the door 2 is closed, the distance between the end face of the door panel 21 on the door opening side and the corresponding side wall of the accommodation space is δ1, and 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. γ is also the vertical distance that the first interference position moves toward the corresponding side wall of the accommodation space. 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, the width direction of the door 2 and the width direction of the accommodation space form an angle.

[0104] According to the embodiment of the present application, the position of the door panel 21 on the door opening side where interference is most likely to occur is determined as the first interference position, and the position of the first interference position is determined. On this basis, the conditions that need to be met for the first interference position not to interfere are determined, thereby determining the law that needs to be satisfied between the initial gap δ1 on the door opening side of the door body assembly and the movement of the door panel 21 to ensure normal use of the embedded refrigeration device.

[0105] On the basis of the above, under the premise of ensuring that the opening side of the door panel 21 does not interfere, in order to ensure the aesthetics and safety of the embedded refrigeration equipment, the initial gap δ1 on the opening side of the door panel 21 generally does not exceed 5 mm. The embodiment of the present application further provides an upper limit value of δ1.

[0106] According to an embodiment of the present application, the spacing δ1 satisfies: δ1≤γ max .

[0107] Among them, γ max is the upper limit of δ1, corresponding to the value of γ when λ is zero and Δθ is Δθcrit.

[0108] Combination Figure 2 and Figure 3 , γ is the vertical distance that the first interference position moves toward the side wall of the corresponding accommodation space, λ is the vertical distance that the second interference position moves toward the side wall of the corresponding accommodation space, Δθ is the rotation angle of the door 2 during the opening process, and Δθ when the first interference position leaves the accommodation space is Δθcrit, where “when the first interference position leaves the accommodation space” corresponds to Figure 2 The point C in the middle is flush with the point e of the cabinet 60, that is, the interference point C is located on the horizontal line where the point e is located. γ and Δs are positively correlated, and Δs is the distance that the door panel 21 moves relative to the door opening side of the door 2 during the opening process of the door 2. Among them, the second interference position is located at the outer corner of the hinge side of the door panel 21. Figure 2 is a top view, the second interference position is from Figure 2 It is a point in the middle, and it can be understood that for the door body assembly, the second interference position is a vertical line. If the outer corner of 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 farthest from the hinge axis of the door 2.

[0109] Among them, 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 panel 21 and the cabinet board can be zero or infinitely close to zero. At this time, in order to ensure that the door opening side of the door panel 21 does not interfere with the cabinet board, the corresponding γ of the door opening side of the door panel 21 is max is the maximum γ required max , and thus δ1 does not exceed γ max .

[0110] Combination Figure 2 and Figure 3 , the hinge axis of the door 2 corresponds to point O in the figure, l1 is the vertical distance from the hinge axis of the door 2 to the inner surface of the door panel 21, l2 is the vertical distance from the hinge axis of the door 2 to the end surface of the door panel 21 on the door opening side, l3 is the vertical distance from the hinge axis of the door 2 to the end surface of the door panel 21 on the hinge side, h is the thickness of the door panel 21, and Δs is the distance that the door panel 21 moves relative to the door 2 during the opening process.

[0111] Figure 2In the figure, the position relationship (indicated by the dotted line in the figure) and the angle relationship of the refrigeration equipment (refrigerator) when the door is not initially opened and when the door 2 is opened to any angle are simplified and annotated. In the figure, the corners where interference may occur during the door opening process are marked with black dots, among which the first interference position point c is likely to interfere with the point e on the right side of the first cabinet panel 601, that is, point e is the critical point for point c to escape interference (leave the accommodation space) during the door opening and closing process. In addition, the second interference position point d is the corner point on the right side of the door panel 21, which is the corner point where the right end face of the door panel 21 first interferes with the left end face of the second cabinet panel 602 adjacent to the right side during the door opening and closing process. It can be seen from the figure that in the initial position, on the left side of the hinge axis, the angle between the hypotenuse oc between point c and the hinge axis and the inner side of the cabinet panel is θ0, and the angle when the refrigerator door 2 is opened to any position is Δ θ, the hypotenuse oc, distance l2 and distance l1 at this position are represented by dotted lines; in the initial position, on the right side of the hinge axis, the hypotenuse between point d and the hinge axis is od, when the angle of the refrigerator door 2 opened to any position is Δθ, at the hypotenuse od, distance l1+h and distance l3 at this position are represented by dotted lines; it can be seen from the figure that during the opening process of the refrigerator door 2, if the cabinet panel does not move toward the door opening side along the refrigerator door 2, as the opening angle increases, point d will soon interfere with the left end face of the second cabinet panel 602, resulting in the refrigerator door 2 being unable to open. Therefore, in order to avoid interference affecting the opening of the door, it is necessary to move the corresponding door panel 21 toward the door opening side by a distance Δs when the door opening angle is Δθ during the opening process.

[0112] According to the embodiment 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, and 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, before the first interference position leaves the accommodation space, the larger the movement distance Δs of the door panel 21 relative to the box door 2 is, the larger δ1 is at this time, so as to prevent the door panel 21 from hitting the first cabinet panel 601 during the movement.

[0113] According to an embodiment of the present application, δ1 is positively correlated with l1, l3, h and the maximum Δs before the first interference position leaves the accommodating space, wherein l1 is the vertical distance from the hinge axis of the door 2 to the inner surface of the door panel 21, l2 is the vertical distance from the hinge axis of the door 2 to the end face of the door opening side of the door panel 21, l3 is the vertical distance from the hinge axis of the 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 the door panel 21 moves relative to the door 2 during the opening of the door 2.

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

[0115] In one embodiment, δ1≥γ=a×cosα-l2.

[0116] in,

[0117] As described above, Δθ is the angle of rotation of the door 2 during the opening process, and Δs is the distance that the door panel 21 moves relative to the opening side of the door 2 during the opening process.

[0118] Therefore, when l1 and l2 are determined, the relationship between δ1 and Δs can be obtained. When Δs is determined, Δθ can be obtained. crit , where Δθ crit is the value of Δθ when the first interference position leaves the accommodation space.

[0119] According to an embodiment of the present application, the door panel 21 has a second interference position, and the second interference position is located at the outer corner of the hinge side of the door panel 21; when the box door 2 is closed, the distance between the end face of the hinge side of the door panel 21 and the side wall of the accommodating space corresponding thereto is δ2. As described above, δ1 can be obtained when the initial gap δ2 on the hinge side of the door body is determined. If δ2 itself is uncertain, δ2 can be further determined based on the known conditions of the door body assembly. Specifically, δ2 is greater than the movement distance λ of the second interference position along the width direction of the accommodating space before the second interference position leaves the accommodating space, and λ is also the vertical distance that the second interference position moves toward the side wall of the accommodating space corresponding thereto.

[0120] On the basis of the above, under the premise of ensuring that the door assembly does not interfere with each other, in order to ensure the aesthetics and safety of the embedded refrigeration equipment, the embodiment of the present application further provides an upper limit value of δ2.

[0121] According to an embodiment of the present application, the interval δ2 satisfies: δ2≤λmax.

[0122] Among them, λmax is the value of λ when γ is zero and Δθ is Δθcrit. That is, when γ is zero, the initial gap δ1 on the door 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 on the hinge side of the door panel 21 is the maximum λmax required.

[0123] Among them, γ being zero means that δ1 can be zero at this time, that is, the initial gap between the door opening side of the door panel 21 and the cabinet panel 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 cabinet panel, the corresponding λmax of the hinge side of the door panel 21 is the required maximum λmax, and then δ2 does not exceed λmax.

[0124] According to an embodiment of the present application, λ is negatively correlated with Δs, and γ is a vertical distance that the first interference position moves toward a side wall of the corresponding accommodation space.

[0125] According to an embodiment of the present application, δ2 is positively correlated with l1, l3 and h, and negatively correlated with the maximum Δs before the first interference position leaves the accommodation space. That is, when l1, l2, l3 and h are larger, δ2 is larger in order to avoid interference between the second interference position and the second cabinet board 602. On the contrary, if the displacement Δs of the door panel 21 toward the door opening side of the box door 2 is smaller in order to avoid interference on the hinge side of the door panel 21 during the door opening process, the required δ2 is smaller.

[0126] In one embodiment, the spacing δ2 satisfies: δ2≥λ=b*cosβ-l3.

[0127] in,

[0128] Thus, when l1 and l3 are determined, the relationship between δ2 and Δs can be obtained. When δ1 and δ2 are equal, that is, the initial gaps on both sides of the door panel 21 are equal, the value range of Δs can be obtained, and further the value range of δ1 and δ2 can be obtained.

[0129] The above formula for calculating δ1 and δ2 does not constitute a restriction on δ1 and δ2. For example, the above calculation formula may also have a correction coefficient or correction parameter. In addition, the above calculation formula is for the case where the hinge axis is determined. If the door 2 is installed with a double-axis hinge or a movable hinge, the hinge axis will change as the door 2 is opened, and the calculation formulas of δ1 and δ2 will also change adaptively. The formula needs to calculate the moving distance of the hinge axis. In addition, if there is an installation gap between the door panel 21 and the 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 door 2 to the sliding surface of the door panel 21.

[0130] 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, the movement amount Δs of the door panel 21 is determined, and then the value range of δ1 and the value range of δ2 can be obtained from Δs.

[0131] In the embodiment of the present application, when all parameters of the door assembly are known and δ2 is known, δ1 can be determined. Alternatively, according to the embodiment of the present application, when δ1 and δ2 are determined, in this case, the functional relationship of Δs can be determined by δ1 and δ2, and then a sliding mechanism or traction cabinet that meets the requirements is obtained based on Δs. Alternatively, when the width of the accommodating space is determined, and the door assembly is determined except Δs, the specific value of δ1+δ2 can be obtained at this time, and then Δs at this time can be obtained based on δ1+δ2. Further, when the width of the accommodating space is determined, the specific value of δ1+δ2 can be obtained at this time, and in order to ensure the installation is beautiful and reliable, generally δ1=δ2, and then δ1 and δ2 can be obtained at this time, respectively, and then Δs at this time can be obtained based on δ1 and δ2.

[0132] Combination Figure 2 and Figure 3 , when the door 2 is closed, the distance between the end face of the door panel 21 on the door opening side and the side wall corresponding to the accommodating space is δ1, and δ1 is 0.5mm-6mm. In this case, the installation requirements of the door assembly can be met to ensure the hidden installation of the refrigeration equipment. At the same time, the door opening process can ensure that the door assembly does not interfere with the installation body, thereby 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 δ1 is 0.5mm-6mm.

[0133] In addition, the distance between the end face of the hinge side of the door panel 21 and the side wall corresponding to the accommodating 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 accommodating space is δ2, which is 0.5mm-6mm. 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.

[0134] According to an embodiment of the present application, the vertical distance from the hinge axis of the door to the inner surface of the door panel is l1, the vertical distance from the hinge axis of the door to the end surface of the door panel on the door opening side is l2, the vertical distance from the hinge axis of the door to the end surface of the hinge side of the door panel is l3, the thickness of the door panel is h, l1 is 5mm-50mm, l2 is 240mm-700mm, l3 is (300mm to 700mm) minus l2, and h is 10mm to 25mm. In this case, the overall size of the door body assembly obtained is suitable, and it is easy to ensure the confidentiality of the refrigeration equipment, and it can prevent interference with the door body assembly. Among them, commonly used values ​​of l2 include 597mm, 600mm, 747mm, 750mm, 607mm, and 610mm. Common values ​​of h include 16mm, 18mm, 20mm, 22mm, and 25mm.

[0135] According to the embodiment of the present application, the movement distance Δs does not change more than 3 mm for every 0.5° increase in the door opening angle of the door assembly. That is, the movement of the door panel is ensured to be as uniform as possible, and the door panel is prevented from suddenly moving at a large angle, thereby making the door panel as concealed as possible and preventing users from panicking about the movement of the door panel.

[0136] 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.

[0137] In one embodiment, when the opening angle Δθ of the door assembly is 0.5°, the moving distance Δs is 0.3 mm to 0.5 mm, and the moving distance Δs does not change by more than 3 mm when the opening angle of the door assembly increases by 0.5°.

[0138] According to the embodiment of the present application, the relevant parameters of the door assembly during the door opening process can be referred to the following table:

[0139] Table 1

[0140] According to the embodiment of the present application, the positions on the door panel 21 that are most likely to cause interference are first determined as the first interference position and the second interference position, 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 that need to be met for no interference to occur at the first interference position and the conditions that need to be met for no interference to occur at the second interference position are determined, thereby determining the rules that need 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 to ensure the normal use of the embedded refrigeration device.

[0141] According to an embodiment of the present application, when the size of the door body assembly is limited to the size in the above Table 1, γ is between -24 mm and 0.4 mm, λ is between -1 mm and 2.2 mm, and γ≤δ1, λ≤δ2.

[0142] According to an embodiment of the present application, when the size of the door body assembly is limited to the size in the above Table 1, during the opening process of the door panel assembly, the angle between the line connecting the first interference position and the hinge axis of the box door and the horizontal position is set to α, and the angle between the line connecting the second interference position and the hinge axis of the box door and the horizontal position is set to β, the angle α is 2.4°-21°, and the angle β is 66° to 72°.

[0143] According to the embodiment of the present application, during the installation of the embedded refrigeration device, δ1 and δ2 can be manually controlled. Of course, it is also possible to set corresponding limit components on the door opening side and the hinge side of the embedded 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 may be an auxiliary installation tool, the size of which corresponds to the size of δ1 and δ2, and then during the installation process, the auxiliary installation tool is used to ensure that the initial gap between the door panel 21 and the cabinet 60 meets the above settings.

[0144] According to an embodiment of the present application, the sliding door mechanism 7 includes a sliding mechanism and a traction mechanism.

[0145] According to one embodiment of the present application, see 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 be connected to the door panel 21. Both ends of the flexible cable 706 are respectively connected to the first slider 714 and the second slider 713. When the first slider 714 moves on the first guide rail, the first slider 714 drives the second slider 713 to move in the opposite direction on the second guide rail through the flexible cable 706, so as to drive the door panel 21 to move relative to the width direction of the box door 2.

[0146] It can be understood that the sliding mechanism of the present embodiment can be arranged on the box door 2, one of the first slider 714 and the second slider 713 is transmission-connected to the box door 2 or the box body 1, and the other is slidingly connected to the door panel 21 arranged on the outside of the box door 2, so that when the box door 2 rotates, the first slider 714 and the second slider 713 slide relative to each other to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid obstacles on both sides during the process of turning the box door 2 open and close.

[0147] Specifically, taking the first slider 714 connected to the box body 1 through the traction mechanism and the second slider 713 connected to the door panel 21 as an example, the first base 717 of this embodiment can be set on the box 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 pull the second slider 713 to move synchronously through the flexible cable 706, thereby driving the door panel 21 to slide relative to the box door 2.

[0148] By properly setting the extension direction of the flexible cable 706 , the first slider 714 and the second slider 713 move in opposite directions during movement, so as to drive the door panel 21 to avoid obstacles.

[0149] For example, when the door 2 is rotated to the outside of the box body 1 to open, the door 1 drives the first slider 714 to slide in the direction close to the first hinge 4 through the traction mechanism, 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, thereby preventing the door panel 21 from interfering with obstacles on the outside. When the door 2 is rotated to one side of the box body 1 to close, the box body 1 drives the first slider 714 to slide in the direction 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, thereby preventing the door panel 21 from interfering with obstacles after closing.

[0150] It is understandable that the first slider 714 can also be connected to the door panel 21, and correspondingly, the second slider 713 is connected to the box door 2 or the box body 1 through a traction mechanism. The working process is the same as that of the above embodiment and will not be repeated here.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] In practical applications, due to factors such as machine tool accuracy, tool wear, and material non-uniformity, there will be certain errors in the processing of the first guide rail, the second guide rail, and the base. These errors may include dimensional errors (such as deviations in length, width, and height), shape errors (such as straightness, flatness, roundness, etc.), and position errors (such as coaxiality, parallelism, and perpendicularity). The parallelism between the first and second guide rails is evaluated by measuring the relative position deviation between them. This deviation needs to be controlled within a certain tolerance range to ensure smooth sliding of the slider and stable operation of the system. This tolerance range is usually determined based on design requirements, usage environment, and system accuracy.

[0158] It should be noted that in this embodiment, parallelism and verticality should not be strictly defined in a geometric sense. At least the manufacturing and installation errors should be considered, and the errors of plus or minus 10° should be understood as within the scope of protection of the patent.

[0159] In one embodiment of the present application, 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 both ends are respectively connected to one end of the first slider 714 and the second slider 713; the second flexible cable passes around the other end of the first base 717, and both ends are respectively connected to the other ends of the first slider 714 and the second slider 713.

[0160] In this embodiment, one end of the first flexible rope is passed around the first base 717 and connected to the first slider 714 and the second slider 713 respectively. When the first slider 714 slides in the direction away from the end of the first base 717 driven by the box door 2 or the box body 1 through the traction mechanism, the first slider 714 drives the second slider 713 to slide in the direction close to the end of the first base 717 through the first flexible rope. At the same time, the other end of the second flexible rope is passed around the first base 717 and connected to the first slider 714 and the second slider 713 respectively. When a slider 714 slides toward the other end away from the first base 717 under the drive of the box door 2, the first slider 714 drives the second slider 713 to slide toward the other end close to the first base 717 through the second flexible rope, thereby achieving that when the first slider 714 slides toward both ends of the first base 717 respectively, the second slider 713 and the first slider 714 can be driven to slide in the opposite direction, thereby enabling the door panel 21 to slide relative to the box door 2 as the box door 2 rotates when the box door 2 is opened and closed, so as to avoid interference with obstacles and affecting the opening and closing of the box door 2.

[0161] The flexible rope 706 is one of steel wire rope, steel strand or hemp rope. The flexible rope 706 is selected according to the load, working environment and use requirements that it needs to bear. For occasions that need to withstand large loads and harsh environments, it is recommended to choose steel wire rope or steel strand; for occasions with small loads and mild environments, hemp rope can be considered. On the premise of meeting the use requirements, consider the cost differences of different materials and choose the most cost-effective material. In addition, steel wire rope and steel strand may need regular inspection and maintenance during use to ensure their performance and safety; hemp rope is relatively easy to replace and maintain.

[0162] Specifically, the second slider 713 and the first slider 714 are both provided with a connector 711 for fixing the flexible cable 706 .

[0163] In one embodiment of the present application, Figure 5As shown, the sliding mechanism also 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, and a first limiting groove is formed, and both ends of the first limiting groove are connected to one end of the first guide rail and the second guide rail, and a part of the first flexible cable can be slidably set in the first limiting groove; the second fixed seat 702 is connected to the other end of the first base 717, and a second limiting groove is formed, and both ends of the second limiting groove are connected to the other end of the first guide rail and the second guide rail, and a part of the second flexible cable can be slidably set in the second limiting groove.

[0164] In this embodiment, by setting the first fixed seat 701 and the second fixed seat 702 at both ends of the first base 717, the first fixed seat 701 and the second fixed seat 702 are respectively formed with the first limiting groove and the second limiting groove connected to the first guide rail and the second guide rail, respectively, to limit and guide the positions of the first flexible rope and the second flexible rope, so that the sliding of the first flexible rope and the second flexible rope is smoother.

[0165] Specifically, a first fixing hole is provided on the first fixing seat 701, and a first waist-shaped hole extending along the width direction of the first base 717 is provided on the first base 717; the sliding mechanism also includes a first adjusting member 704, and 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 rope by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0166] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the first fixing seat 701 can be adjusted along the width direction of the first base 717, so that the first fixing seat 701 can tighten or loosen the first flexible rope, thereby adjusting the tightness of the first flexible rope.

[0167] 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 the first slider 714 and the second slider 713 at both ends, when the first fixed seat 701 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the first flexible cable is adjusted in tightness accordingly, and the second flexible cable is also adjusted in tightness accordingly under the pulling of the first fixed seat 701 on the first flexible cable.

[0168] It is understandable that a first fixing hole can also be set on the second fixing seat 702; a first waist-shaped hole extending along the width direction of the first base 717 is provided on the first base 717; the sliding mechanism also includes a first adjusting member 704, the first adjusting member 704 passes through the first fixing hole, and can be slidably set in the first waist-shaped hole to adjust the tightness of the second flexible rope by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0169] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the second fixing seat 702 can be adjusted along the width direction of the first base 717, so that the second fixing seat 702 can tighten or loosen the second flexible rope, thereby adjusting the tightness of the second flexible rope.

[0170] 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 the first slider 714 and the second slider 713 at both ends, when the second fixed seat 702 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the second flexible cable is adjusted in tightness accordingly, and the first flexible cable is also adjusted in tightness accordingly under the pulling of the second fixed seat 702 on the second flexible cable.

[0171] Further, in some embodiments, the first fixing seat 701 is provided with a second waist-shaped hole extending in the width direction of the first base 717. The first base 717 is provided with a second fixing hole. The sliding mechanism further includes a second adjusting member 703, which passes through the second waist-shaped hole and the second fixing hole in sequence and is fixed in the external structure, so as to adjust the position of the first fixing seat 701 relative to the external structure through the position of the second adjusting member 703 in the second waist-shaped hole.

[0172] In this embodiment, the first fixing seat 701 is fixed to the external structure by providing a second waist-shaped hole on the first fixing seat 701, and the second adjusting member 703 is sequentially passed through the second waist-shaped hole and the second fixing hole to be fixed to the external structure, so as to fix the sliding mechanism to the external structure (such as the box door 2). At the same time, the second adjusting member 703 can be fine-tuned in the position along the second waist-shaped hole to adjust the position of the first fixing seat 701, so as to cooperate with adjusting the position of the first fixing seat 701 relative to the external structure.

[0173] It is understandable that the second fixing seat 702 may also be provided with a second waist-shaped hole extending along the width direction of the first base 717; the second adjusting member 703 passes through the second waist-shaped hole and the second fixing hole in sequence and is fixed in the external structure, so that the position of the second fixing seat 702 relative to the external structure is adjusted 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 fixing hole are similar to those in the above embodiment and are not described in detail here.

[0174] Furthermore, in some embodiments, a rotatable support bearing is provided in the first limit groove; a portion of the first flexible cable abuts against the support bearing in the first limit groove. In this embodiment, by abutting a portion of the first flexible cable against the support bearing, the activity of the first flexible cable and its extension direction can be adjusted, so that the first flexible cable can be connected to the first slider 714 and the second slider 713 around the end of the first base 717.

[0175] It is understandable that a rotatable support bearing may also be provided in the second limit groove; a portion of the second flexible cable abuts against the support bearing in the second limit groove to adjust the extension direction of the second flexible cable, making it convenient to connect the second flexible cable around the end of the first base 717 and the first slider 714 and the second slider 713.

[0176] Specifically, in some embodiments, the support bearing includes a first bearing 705 and a second bearing 716 , which are respectively located at one end of the same side of the first guide rail and the second guide rail and are respectively located on both sides of the first base 717 .

[0177] In one embodiment of the present application, Figure 5 As shown, 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 sliding block 714, and the second rotating shaft fixing seat 710 is used to be connected to the box body 1. One end of the traction rod 709 is rotatably connected to the first 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.

[0178] In this embodiment, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are respectively fixed on the first slider 714 and the box body 1, and the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are connected by a traction rod 709, so that the distance between the first slider 714 and the second rotating shaft fixing seat 710 remains unchanged. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes, so that the first slider 714 is pulled through the transmission connection of the traction rod 709, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, so that the first slider 714 slides on the first base 717, and drives the second slider 713 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0179] Specifically, one end of the traction rod 709 is rotatably connected to the first rotating shaft fixing seat 707 via a pin shaft 708 and a third bearing 715 , and the other end is rotatably connected to the second rotating shaft fixing seat 710 via another pin shaft 708 and another third bearing 715 .

[0180] In another embodiment of the present application, Figure 1 and Figure 4 As shown, a door assembly is provided, comprising: a box door 2, a door panel 21, and a sliding mechanism as provided in any of the above embodiments. The box door 2 is rotatably connected to the box body 1, and is suitable for opening or closing the storage space of the box body 1. The door panel 21 is slidably arranged on the outside of the box door 2; the sliding mechanism is arranged on the box door 2, the first slider 714 is used for transmission connection with the box body 1, and the second slider 713 is connected to the door panel 21. In the process of opening or closing the box door 2, the first slider 714 and the second slider 713 move in opposite directions to drive the door panel 21 to move relative to the box door 2.

[0181] Specifically, when the door 2 is rotated to the outside of the box body 1 to open, the first slider 714 slides toward the first hinge 4 through the traction mechanism under the drive of the box body 1, and the first slider 714 drives the second slider 713 to slide away from the first hinge 4 through the flexible cable 706, thereby driving the door panel 21 to slide away from the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles outside. Similarly, when the door 2 is rotated to one side of the box body 1 to close, the sliding mechanism drives the door panel 21 to slide toward the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0182] According to the door body assembly of the embodiment of the present application, a sliding mechanism is arranged on the box door 2, and the sliding mechanism is respectively connected to the box door 2 and the door panel 21, so that when the box door 2 is rotated to open or close relative to the box body 1, the door panel 21 is driven to slide in the width direction of the box door 2, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening of the box door 2.

[0183] It can be understood that if the sliding mechanism has the beneficial effects of the above-mentioned embodiments, then the door body assembly will correspondingly have the beneficial effects of the above-mentioned embodiments. Its specific implementation method can refer to the above-mentioned embodiments, and this application will not elaborate on it.

[0184] In one embodiment of the present application, Figures 5 and 6 As shown, a first connecting block 712 is disposed on the second sliding block 713 , and a slot for hanging the door panel 21 is formed on the first connecting block 712 .

[0185] In this embodiment, by providing the first connection block 712 on the second slider 713 and providing a slot on the first connection block 712, correspondingly, the door panel 21 is provided with a connection component (such as a hook, a connector, etc.) adapted to the slot, so that the door panel 21 is installed on the first connection block 712, so that the door panel 21 can slide with the second slider 713. At the same time, it is also convenient for the user to remove the door panel 21 from the second slider 713 when needed, meeting the user's usage needs in different scenarios.

[0186] According to another embodiment of the present application, in addition to the above double guide rail and double slider structure, the sliding mechanism of the present application can also adopt Figures 8 to 10 The sliding mechanism includes a guide member 730 , a sliding member 740 , a connecting rod assembly 750 and a driving rod 760 .

[0187] The guide member 730 is configured to be disposed on the door, and a guide structure 731 is disposed on the guide member 730 . The sliding member 740 is configured to be disposed on the door panel, and the sliding member 740 is movably disposed on the guide member 730 along the width direction of the door.

[0188] The connecting rod assembly 750 is movably disposed on the guide structure 731 and can undergo structural deformation under the guidance of the guide structure 731 . The second end of the connecting rod assembly 750 is movably connected to the sliding member 740 .

[0189] The driving rod 760 is disposed in the box body and movably connected to the first end of the connecting rod assembly 750 to drive the connecting rod assembly 750 to undergo structural deformation during the opening and closing process of the box door, and then the connecting rod assembly 750 drives the sliding member 740 to drive the door panel to move along the width direction.

[0190] It is understandable that, as shown in the figure, the box body is installed with a hinge, the hinge is provided with a hinge shaft, and the box door is rotatably provided on the hinge shaft to realize the opening or closing of the box door relative to the box body.

[0191] The guide structure 731 can ensure that the connecting rod assembly 750 moves along a predetermined path or direction, prevent it from deviating from a predetermined trajectory, and can guide the structural deformation of the connecting rod assembly 750, thereby driving the sliding member 740 to move along the width direction of the door.

[0192] Optionally, the guide structure 731 can guide the connecting rod assembly 750 to move along the tooth shape of the sprocket by cooperating with the sprocket and the chain, and the guide structure 731 can also guide the connecting rod assembly 750 to move along the cross section of the guide rail by cooperating with the sliding block 742 and the guide rail.

[0193] The connecting rod assembly 750 changes the distance between the second end of the connecting rod assembly 750 and the hinge through its own structural deformation, thereby causing the distance between the sliding member 740 and the hinge to change, further achieving a change in the distance between the door panel connected to the sliding member 740 and the hinge.

[0194] Optionally, the connecting rod assembly 750 may be a parallel four-bar linkage or a crank rocker mechanism.

[0195] With respect to the sliding mechanism shown in this embodiment, the guide member 730 is arranged on the box door, the sliding member 740 is arranged on the door panel, the sliding member 740 is movably arranged on the guide member 730 along the width direction of the box door, and a guide structure 731 is arranged on the guide member 730, the guide structure 731 can guide the connecting rod assembly 750 to perform structural deformation, and the second end of the connecting rod assembly 750 is movably connected to the sliding member 740, when the box 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 rotate. The sliding member 740 moves in the direction away from the hinge, thereby driving the door panel to move along the width direction of the door in the direction away from the hinge, so that the door panel and the cabinet body on the side do not interfere with the cabinet body; when the 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 in the direction close to the hinge, thereby driving the door panel to move along the width direction of the door in the direction close to the hinge, so that the door panel returns to its original position, ensuring that the door panel does not interfere with the cabinet body around the refrigeration equipment.

[0196] In some embodiments, Figure 8 As shown, the connecting rod assembly 750 includes a first connecting rod 751 and a second connecting rod 752 .

[0197] The driving rod 760 is rotationally 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 rotationally connected through the 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 connecting rod 752 is rotationally connected to the sliding member 740.

[0198] The driving rod 760 is used to drive the first end of the first connecting rod 751 to move along the width direction, and the first connecting rod 751 is used to drive the first hinge shaft 753 to move along the thickness direction to change the angle between the first connecting rod 751 and the second connecting rod 752, and then the second connecting rod 752 drives the sliding member 740 to move in the direction opposite to the driving direction of the driving rod 760.

[0199] It is understandable that the driving rod 760 provides driving force to the first end of the first connecting rod 751, and the guide structure 731 can constrain the moving path of the first hinge shaft 753, so that the first hinge shaft 753 can only move along the thickness direction of the door, thereby changing the angle between the first connecting rod 751 and the second connecting rod 752, so that the second connecting rod 752 moves along the width direction.

[0200] During the process of the door opening the box body, the driving rod 760 drives the first end of the first connecting rod 751 to move along the width direction toward the direction close to the hinge, and the first connecting rod 751 drives the first hinge shaft 753 to move along the thickness direction toward the sliding member 740, so that the angle between the first connecting rod 751 and the second connecting rod 752 becomes larger, pushing the second connecting rod 752 to move in the direction away from the hinge, and then driving the sliding member 740 to move along the width direction away from the hinge, so as to prevent the door panel and the side cabinet from interfering with the cabinet body.

[0201] During the process of closing the door, the driving rod 760 drives the first end of the first connecting rod 751 to move in the direction away from the hinge along the width direction, and the first connecting rod 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 connecting rod 751 and the second connecting rod 752 becomes smaller, pushing the second connecting rod 752 to move in the direction close to the hinge, and then driving the sliding member 740 to move in the width direction close to the hinge, so that the door panel returns to its original position, ensuring that the door panel does not interfere with the cabinet body around the refrigeration equipment.

[0202] In this embodiment, a first connecting rod 751, a second connecting rod 752 and a first hinge shaft 753 are provided in the connecting rod assembly 750, and the first hinge shaft 753 is limited to movement in the thickness direction. By changing the angle between the first connecting rod 751 and the second connecting rod 752, the second connecting rod 752 can drive the sliding member 740 to move in the width direction, thereby realizing movement of the door panel relative to the box door. The structure is simple and the volume is small.

[0203] In some embodiments, Figure 8 As shown, the driving rod 760 includes: a linkage.

[0204] The first end of the linkage is configured to be rotatably disposed at a fixed position on the housing 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 disposed away from the hinged position between the door and the housing.

[0205] When the door opens the box, the linkage member drives 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.

[0206] When the door closes the box, the linkage member drives 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.

[0207] It can be understood that the first end of the linkage in the present embodiment is rotatably provided on the hinge. When the box door rotates relative to the box body around the hinge axis, the second end of the linkage rotates in a circle with the hinge axis as the center. Since the first end of the linkage is staggered with the hinge axis, the distance between the second end of the linkage and the hinge will change with the rotation of the linkage, thereby driving the connecting rod assembly 750 to move closer to or away from the hinge along the width direction of the box door.

[0208] During the process of the box door opening the box body, as the box door rotates, the box door drives the linkage to rotate, and 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.

[0209] During the process of closing the box body by the box door, as the box door rotates, the box door drives the linkage to rotate, and 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.

[0210] In this embodiment, the first end of the linkage is set to deviate from the hinge position between the door and the box body, so that the second end of the linkage can drive the first end of the first connecting rod 751, so that the second connecting rod 752 can 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 drive connecting rod assembly 750, so that the sliding member 740 can drive the door panel to move in the width direction. Without the need for an additional driving device, the movement of the door panel relative to the door can be synchronized with the opening and closing of the door.

[0211] In some embodiments, Fig. 9 As shown, the guiding structure 731 includes: a first limiting groove 7311 .

[0212] The first limiting groove 7311 extends along the thickness direction.

[0213] 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 .

[0214] 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 along the thickness direction, thereby allowing the angle between the first connecting rod 751 and the second connecting rod 752 respectively connected to the first hinge shaft 753 to change, and the second end of the first connecting rod 751 and the second end of the second connecting rod 752 move in opposite directions.

[0215] The first limiting groove 7311 of this embodiment can guide the moving direction of the first hinge shaft 753, and the first limiting groove 7311 can be directly opened on the upper surface of the guide member 730 without occupying additional space, thereby ensuring the compactness of the structure of the sliding mechanism.

[0216] In some embodiments, Fig. 9 As shown, the guide structure 731 also includes: a second limiting groove 7312 .

[0217] The second limiting groove 7312 extends along the width direction and is connected to the first limiting groove 7311 .

[0218] The driving rod 760 is rotatably connected to the first end of the first connecting rod 751 through the second hinge shaft 754, and the second end of the second connecting rod 752 is rotatably connected to the sliding member 740 through the 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 extension direction of the second limiting groove 7312;

[0219] The second hinge axis 754 and the third hinge axis 755 are respectively arranged on two sides of the first limiting groove 7311 .

[0220] 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 along the width direction, and then the second connecting rod 752 can drive the sliding member 740 to move along the width direction. The second limiting groove 7312 of this embodiment prevents the moving direction of the sliding member 740 from being offset, thereby ensuring the reliability and stability of the moving direction of the sliding member 740, thereby ensuring the reliability of the movement of the door panel along the width direction of the box door.

[0221] In some embodiments, Figure 8 As shown, the sliding mechanism further includes: an elastic member 770 .

[0222] The elastic member 770 is disposed between the guide member 730 and the sliding member 740 .

[0223] When the connecting rod assembly 750 drives the sliding member 740 to move toward a side away from the hinge position, the sliding member 740 compresses the elastic member 770 in the process of driving the door panel to move.

[0224] When the connecting rod 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 to move toward the hinge position.

[0225] The hinged position is located between the box door and the box body, and the box door is rotatably arranged on the box body based on the hinged position.

[0226] It is understandable that when the connecting rod assembly 750 drives the sliding member 740 to move toward a side away from the hinge position, the elastic member 770 is squeezed in a direction away from the hinge to accumulate elastic potential energy.

[0227] When the connecting rod 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, driving the sliding member 740 to approach the hinge position.

[0228] Specifically, the elastic member 770 may be an elastic sheet, an elastic block, or a spring.

[0229] In this embodiment, an elastic member 770 is provided in the sliding mechanism. Based on the elastic deformation of the elastic member 770 , it can ensure that the movement of the sliding member 740 relative to the guide member 730 is more stable and reliable.

[0230] In some embodiments, Figures 8 to 10 As shown, the guide member 730 includes a fixing plate 732 and a sliding groove 733 .

[0231] The fixing plate 732 is configured to be disposed on the box door.

[0232] The slide slot 733 is disposed on the fixed plate 732 and extends along the width direction. At least a portion of the sliding member 740 is movably disposed in the slide slot 733 along the width direction.

[0233] It can be understood that the fixed plate 732 of this embodiment is used to be fixedly connected to the box door, and the slide groove 733 is used to guide the sliding member 740 to move along the width direction of the box door, based on the sliding cooperation between the sliding member 740 and the slide groove 733, to ensure that the sliding member 740 can move stably and reliably along the width direction of the box door.

[0234] In some embodiments, Fig. 9 and Fig.10 As shown, the guide member 730 further includes a sliding sleeve 734 , which is disposed at one end of the sliding slot 733 away from the hinged position.

[0235] The sliding member 740 includes a guide rod 741 and a sliding block 742. The guide rod 741 is inserted into the sliding sleeve 734. A sliding contact 745 is provided on the guide rod 741. The sliding contact 745 is movably provided in the sliding groove 733 along the width direction. The sliding block 742 is connected to the guide rod 741 and is configured to be connected to the door panel.

[0236] The elastic member 770 is disposed between the sliding sleeve 734 and the sliding contact 745 .

[0237] It can be understood that the slide groove 733 of this 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 slide groove 733, and as the sliding member 740 moves on the slide groove 733, the sliding contact 745 also moves accordingly, the sliding sleeve 734 is fixedly arranged relative to the fixed plate 732, and 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 close to the hinge, the elastic member 770 releases its elastic potential energy and stretches, 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 extension of the elastic member 770.

[0238] In addition, 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 along the width direction of the door, the sliding can drive the door panel to move along the width direction of the door.

[0239] In some embodiments, Figure 8 As shown, the elastic member 770 includes a spring, which is sleeved on the outer side of the guide rod 741 and limited between the sliding sleeve 734 and the sliding contact 745 .

[0240] It is understandable 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 the spring changes its state of compression and extension in the length direction of the guide rod 741, 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, so as to facilitate the stopping of the two ends of the spring during compression and extension. The spring of this embodiment makes the structure of the door panel simple and compact when it is reset relative to the box door, and the volume is small, which saves the installation space of the door panel.

[0241] In some embodiments, Figure 8 and Fig. 9 As shown, the sliding member 740 further includes: a first connecting arm 743 and a second connecting arm 744 .

[0242] The first connecting arm 743 and the second connecting arm 744 are spaced apart 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 .

[0243] The sliding sleeve 734 and the sliding contact 745 are located between the first connecting arm 743 and the second connecting arm 744 .

[0244] It is understandable 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 respectively, so that the connection between the guide rod 741 and the sliding block 742 is more secure, and when the sliding block 742 moves along the width direction of the box door, it is easier to fit the width direction.

[0245] Furthermore, the sliding block 742 of the present embodiment is arranged perpendicularly to 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 on the top of the box door, and the door panel and the box door can fit parallel to each other, ensuring the flatness of the door panel installed on the box door and facilitating the movement of the door panel along the box door.

[0246] Of course, in addition to the above-mentioned slide rail slider or connecting rod form, the sliding mechanism can also be in the form of a gear rack, or 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 by the above examples. For example, the traction mechanism can be in the form of a cylinder, a rope, etc., and the specific examples are not given one by one. In addition, the traction mechanism can be an electric structure or a mechanical structure.

[0247] In one embodiment of the present application, Figure 4 , Fig.11 and Fig.12 As shown, the door assembly further includes: a first driven guide rail mechanism 8. The first driven guide rail mechanism 8 is arranged parallel to 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, and the third slider 813 is slidably arranged on the third guide rail. The third slider 813 is provided with a second connecting block 812, and the second connecting block 812 is formed with a slot for the door panel 21 to be hung.

[0248] In this embodiment, a first driven rail mechanism 8 is provided on the box door 2 in parallel with the sliding mechanism, the first driven rail mechanism 8 has a second base 817, a third rail and a third slider 813 that can slide along the third rail are provided on the second base 817, and the third slider 813 is connected to the door panel 21 through the second connecting block 812. The third slider 813 can slide with the door panel 21 when the door panel 21 slides relative to the box door 2, and plays a supporting and auxiliary role in the sliding of the door panel 21, so that the door panel 21 slides more smoothly relative to the box door 2. At the same time, the first driven 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 slide more stably. In addition, the slot on the second connecting block 812 can facilitate the user to install the door panel 21 on the driven rail mechanism.

[0249] Furthermore, the first driven guide rail mechanism 8 also includes a third fixed seat 801 and a fourth fixed seat 802 , and the third fixed seat 801 and the fourth fixed seat 802 are also provided with limiting grooves similar to the first fixed seat 701 and the second fixed seat 702 .

[0250] Specifically, a third fixing hole is provided on the third fixing seat 801, and a third waist-shaped hole extending along the width direction of the second base 817 is provided on the second base 817; the third adjusting member 804 passes through the third fixing hole and can be slidably arranged in the third waist-shaped hole to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0251] It is understandable that the fourth fixing seat 802 may also be provided with a third fixing hole; the second base 817 is provided with a third waist-shaped hole extending along the width direction of the second base 817; the third adjusting member 804 passes through the third fixing hole and is slidably arranged in the third waist-shaped hole, so as to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0252] Further, the third fixing seat 801 is provided with a fourth waist-shaped hole extending in the width direction of the second base 817. The second base 817 is provided with a fourth fixing hole. The 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, so that the position of the third fixing seat 801 relative to the external structure is adjusted by the position of the fourth adjusting member 803 in the fourth waist-shaped hole.

[0253] It is understandable that the fourth fixed seat 802 may also be provided with a fourth waist-shaped hole extending along the width direction of the third base 902; the fourth adjustment member 803 passes through the fourth waist-shaped hole and the fourth fixed hole in sequence and is fixed in the external structure, so as to adjust the position of the fourth fixed seat 802 relative to the external structure through the position of the fourth adjustment member 803 in the fourth waist-shaped hole.

[0254] In one embodiment of the present application, Figure 4 , Fig.13 and Fig.14 As shown, the door body assembly also includes a second driven guide rail mechanism 9, which is arranged off-axis from the sliding mechanism.

By adjusting the position of the fixing member in the waist-shaped hole, the position of the first hook 2111 can be fine-tuned, which is convenient for installing the door panel 21 and fine-tuning the position and angle of the door panel 21.

[0291] It is understandable that the structure of the second hook 2112 is similar to that of the first hook 2111 , and will not be described in detail herein.

[0292] In one embodiment of the present application, the door assembly and the cabinet 1 are used to be arranged in an installation space formed between a first cabinet and a second cabinet; during the opening or closing process of the cabinet door 2, the sliding mechanism is configured to drive the door panel 21 to move a preset distance on the cabinet door 2 so that the door panel 21 avoids the side walls of the first cabinet and the second cabinet.

[0293] In this embodiment, the box body 1 is arranged between the first cabinet body and the second cabinet body. It can be understood that the material and color of the door panel 21 can be designed to be similar or the same as the material color of the outer wall of the cabinet body. When the box door 2 is closed, the door panel 21 is flush with the outer walls of the first cabinet body and the second cabinet body on both sides, so that the door panel 21 and the outer wall of the cabinet body can maintain visual consistency with a smaller gap, which is more beautiful.

[0294] When the door 2 is rotated outward to open, the sliding mechanism drives the door panel 21 to slide a preset distance in the direction away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side close to the first hinge 4, which causes the door 2 to be unable to open to a larger angle. When the door 2 is rotated to close, the sliding mechanism drives the door panel 21 to slide a preset distance in the direction close to the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side away from the first hinge 4, which causes the door 2 to be unable to be completely closed and affects the function of the cabinet 1, and when the door 2 is completely closed, the door panel 21 can be restored to a state flush with the cabinet. By designing a reasonable preset distance, it is possible to avoid interference between the door panel 21 and the cabinet walls on both sides when sliding relative to the door 2.

[0295] In another embodiment of the present application, the door assembly and the box body 1 are used to be arranged in a 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.

[0296] In this embodiment, the box body 1 is arranged in a single cabinet. It can be understood that the material and color of the door panel 21 can be designed to be similar 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 with a smaller gap, which is more beautiful.

[0297] When the door 2 is rotated outward to open, the sliding mechanism drives the door panel 21 to slide a preset distance in the direction away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side close to the first hinge 4, which causes the door 2 to be unable to open to a larger angle. When the door 2 is rotated to close, the sliding mechanism drives the door panel 21 to slide a preset distance in the direction close to the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side away from the first hinge 4, which causes the door 2 to be unable to be completely closed and affects the function of the cabinet 1, and when the door 2 is completely closed, the door panel 21 can be restored to a state flush with the cabinet. By designing a reasonable preset distance, it is possible to avoid interference between the door panel 21 and the cabinet walls on both sides when sliding relative to the door 2.

[0301] 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 of the box door 2 to stay as far away as possible from obstacles such as the wall or cabinet of the side door of the box body 1, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the box door 2, causing the box door 2 to be unable to open or close normally.

[0302] The combination of the door 2 and the door panel 21 can prevent the door panel 21 from interfering with surrounding objects when the refrigeration device is opened and closed, greatly improving the convenience of use. This design advantage is particularly obvious in a narrow kitchen environment. In addition, the setting of the sliding mechanism enables the door panel 21 to move smoothly during the opening and closing process, thereby improving the service life and stability of the refrigerator.
