TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigeration, in particular to a door body assembly of an embedded refrigeration device and the embedded refrigeration device. BACKGROUND

[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 seamlessly embed 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 side wall of the cabinet during opening, resulting in poor user experience of the embedded refrigerator.

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

[0100] In today's society, the rapid progress of science and technology has greatly promoted the change of home lifestyle. Among them, the embedded furniture, as a design concept that combines aesthetics and practicality, is favored by 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 the 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 has shown significant advantages in improving the aesthetics and space utilization of the home, it still has a problem that cannot be ignored in the actual use process: that is, the door is easy to interfere or collide with the side wall of the cabinet during opening, resulting in poor user experience of the embedded refrigerator.

[0101] Specifically, in the case of meeting the user's requirements for two different types of refrigerators, namely, a flat full-embedded refrigerator and a full-embedded refrigerator, the refrigerator door (hereinafter referred to as the door) after being connected with the cabinet door panel (hereinafter referred to as the door panel) causes the entire door assembly to be thickened, resulting in that, after the refrigerator is pushed into the accommodating space of the cabinet, only the original single-axis or double-axis structure hinge of the refrigerator is used, and the door assembly with the cabinet door interferes with the cabinet during the opening and closing of the door, thereby causing the door to be unable to be normally opened and used.

[0102] Therefore, the present application provides a door assembly (hereinafter referred to as the door assembly) which can enable the door and the door panel to slide relative to each other, so that, during the opening of the door assembly, the door panel can slide towards the opening side (i.e., the opening side), and, during the opening of the door, the hinge side still maintains the thickness of the door itself, which is consistent with the opening scene of the door without the door panel; during the closing of the door, the door panel moves towards the hinge side to return to the state before the door is opened; thereby achieving the refrigerator embedding installation requirement with or without the door panel.

[0103] Wherein, as the door panel moves away from the cabinet, the door panel moves towards the cabinet panel, and, at the maximum opening angle, the end of the hinge side of the door panel is likely to interfere with the outer surface of the cabinet panel.

[0104] Based on this, the present application provides a door assembly of an embedded refrigeration device, please refer to Figure 1 , which comprises a door 2 and a door panel 21. The door 2 is rotatably connected to a refrigeration box body 1, and the refrigeration box body 1 is embedded in an accommodating space formed by an installation body. The installation body generally refers to a cabinet 60 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 takes the installation body as the cabinet 60 as an example. The door panel 21 is movably installed on the door 2, and the door panel 21 can move along the width direction of the door 2; the door panel 21 is adapted to move relative to the door 2 towards the opening side of the door 2 during the opening of the door 2, and the moving distance is d.

[0105] When the opening angle of the door 2 is ninety degrees, the moving distance d is d1 at this time, and d1 is not less than the sum of the distance t and the distance , wherein t is the distance between the hinge axis of the door 2 and the opening of the accommodating space, is the vertical distance from the hinge axis 101 of the door 2 to the end surface of the hinge side of the door panel 21. In the above case, that is, once the opening angle of the door 2 reaches ninety degrees, the door panel 21 is completely located outside the accommodating space, thereby it can be obviously avoided that the door panel 21 interferes with the inner wall of the accommodating space. At this time, the end surface of the hinge side of the door panel 21 exceeds the installation body, thereby it can also be avoided that the end surface of the hinge side of the door panel 21 interferes with the outer surface of the installation body.

[0106] On the basis of the above, if the maximum opening angle of the door body assembly is greater than ninety degrees, in order to ensure that the door panel 21 does not interfere during the opening process of the door body assembly, it is necessary to further ensure that the distance by which the interference position of the door panel 21 moves towards the cabinet after being not less than ninety degrees. Please refer to Figure 2 , the door panel 21 has an interference position c0 point, and the interference position is located at the outer corner of the hinge side of the door panel 21. The "outer" is relative to the refrigeration cabinet 1, and the side facing away from the refrigeration cabinet 1 is the "outer" side, and vice versa, the side facing towards the refrigeration cabinet 1 is the "inner" side. Since Figure 2 is a top view, the interference position c0 is a point from Figure 2 , it can be understood that for the door body assembly, the interference position is a vertical line. If the outer corner of the hinge side of the door panel 21 is in an arc shape, the interference position is the point farthest from the hinge shaft 101 of the cabinet door 2 on the arc segment.

[0107] Figure 3 In Figure 1 and Figure 2 , the gap between the door panel 21 and the end face of the first cabinet panel 601 on the left is a, and the gap between the door panel 21 and the end face of the second cabinet panel 602 on the right is b, in combination with l1 , the vertical distance from the hinge shaft 101 (corresponding to the o point in the figure) of the hinge 10 to the inner side surface of the door panel 21 is l2 , the distance from the hinge shaft 101 to the opening side end face of the door panel 21 when the cabinet door 2 is not opened is l3 , and the distance from the hinge shaft 101 to the hinge side end face of the door panel 21 is , that is, the length of the door panel 21 is divided into l2 and l3 two parts with the hinge shaft 101 as the dividing point, the thickness of the door panel 21 is h, and the maximum opening angle of the cabinet door 2 is

[0108] It can be understood that , l3、l1 and h are greater, and the moving distance is greater. That is, , l3、l1 and h, the above parameters are positively correlated with the moving distance d. Obviously is not less than 90°.

[0109] In combination with Figure 2 , the positions (the dashed line in the figure represents) of the refrigerator when the refrigerator is initially not opened and when the cabinet door 2 is opened to the maximum opening angle are simplified and annotated in the figure. After the cabinet door 2 is opened to the maximum angle , there will be an interference corner marked with a black dot, wherein the c0 point represents the outer corner point of the right end of the door panel 21 when the door body is not opened, that is, the interference position mentioned in the foregoing, and it is the maximum opening angle At this time, an interference point will be generated on the outer surface of the second cabinet panel 602 adjacent to the right. The angle between the hypotenuse of oc0 and the vertical side l1 at this time is set as α; the maximum opening angle of the door is set. When the door panel 21 is not moving along the door 2, the outermost corner point on the right side of the door panel 21 is c1. The angle between the hypotenuse of c1 and the horizontal position is set to β. The vertical distance between point c1 and the horizontal line passing through the hinge axis 101 (i.e., point o) is set to e. After the door panel 21 moves by a displacement d, the outermost corner point on the right side of the door panel 21 is set to c2. The gap between point c2 and the outer surface of the adjacent second cabinet panel 602 is set to... The positional and angular relationships between points o, c0, c1, and c2 are as follows: Figure 2 As shown.

[0110] According to one embodiment of this application, from Figure 2 From this, we can conclude that when the refrigerator door is opened to its maximum angle... When the distance d is traveled, the following relationship can be obtained: .

[0111] Among them, distance , .

[0112] When the door is opened to its maximum angle When the door panel 21 does not interfere with the outer surface of the second cabinet panel 602 adjacent to the hinge side, the minimum displacement d of the door panel 21 along the cabinet door 2 needs to satisfy the following relationship: ,and >0, in this case, the refrigerator door 2 and the cabinet door 60 can be opened and closed normally. Furthermore, based on... You can get .

[0113] certainly, The calculation formula does not impose a limitation on d. For example, the above calculation formula can also have correction coefficients or correction parameters. Furthermore, the above calculation formula is for the case where the hinge axis 101 is fixed. If the door 2 is installed using a double-axis hinge 10 or a movable hinge 10, the hinge axis 101 will change as the door 2 opens, and thus... The calculation formula also changes adaptively, requiring the calculation of the movement distance of the hinge axis 101. Furthermore, if the door panel 21 and the cabinet door 2 may be perfectly fitted together or there may be a gap, the above calculation formula will differ depending on whether a gap exists between the door panel 21 and the cabinet door 2.

[0114] According to embodiments of this application, in conjunction with Figures 1 to 3 ,get Corresponding to the data in the following table.

[0115]

[0116] Table 1

[0117] According to an embodiment of the present application, the maximum opening angle of the door is between ninety degrees and one hundred and thirty-five degrees, that is, . At this opening angle of the door, all the user's taking and placing requirements can be met, and the opened door panel 21 does not occupy too much use space. Of course, the maximum opening angle of the door may also be other values.

[0118] According to an embodiment of the present application, after the interference site leaves the containing space, and after the interference site corresponds to the mounting body, the distance between the interference site and the panel of the mounting body is , and > 0. At this time, that is, when the interference site leaves the region corresponding to the containing space and moves towards the second cabinet panel 602 on the right side of the cabinet 60, in order to prevent interference, the distance between the interference site and the outer surface of the second cabinet panel 602 is always greater than zero.

[0119] According to still another embodiment of the present application, in combination with Figure 4 and Figure 5 , the moving distance of the door panel 21 is d and the maximum opening angle of the door body assembly is satisfies:

[0120] .

[0121] Wherein, A1 is the safety gap between the corner of the door panel 21 corresponding to the interference site and the panel of the mounting body at the maximum opening angle of the door, B is the assembly gap between the door panel 21 and the cabinet door 2, C is the gap between the cabinet door 2 and the refrigeration cabinet body 1, D1 is the thickness of the door panel 21, D2 is the thickness of the cabinet door 2, and E is the distance from the bottom of the cabinet door 2 to the refrigeration cabinet body 1 at the maximum opening angle of the door.

[0122] Figure 4 and Figure 5 , the door panel 21 and the cabinet door 2 are connected with a sliding mechanism 4, the sliding mechanism 4 is connected with a traction mechanism, and under the driving of the traction mechanism, the door panel 21 is driven to move relative to the cabinet door 2. The sliding mechanism 4 includes a sliding rail and a sliding block moving along the sliding rail (the structure of the sliding mechanism 4 is illustrated later). The sliding mechanism 4 and the traction mechanism are connected through a sliding rail hinge 10.

[0123] Wherein, when the traction mechanism is a connecting rod mechanism, if the transmission ratio of the connecting rod mechanism is 1:1, the moving distance L2 of the sliding rail hinge axis 101 is the moving distance d of the door panel 21 relative to the cabinet door 2.

[0124] Figure 4 and Figure 5 In the formula, when the door body assembly is in the closed position, the farthest distance between the end face of the refrigeration box body 1 corresponding to the hinge side and the center of the slide rail hinge 10 is L, that is, the farthest distance between the end face of the door panel 21 corresponding to the hinge side and the center of the slide rail hinge 10 is L; the distance between the end face of the refrigeration box body 1 corresponding to the hinge side and the center of the slide rail hinge 10 when the door is opened to the maximum opening angle is L1, wherein L1 is a design given quantity, and the displacement of the refrigerator door 2 from the opening to the center of the slide rail hinge 10 when the door is opened to the maximum opening angle is L2 (the maximum displacement).

[0125] , and then the relationship between L2 and can be obtained under the condition that other parameters are determined.

[0126] According to the embodiments of the present application, the difference between A1 and A can also be ignored, and A1 in the formula is replaced by A, wherein A is the safety gap between the interference position of the door panel 21 and the panel of the mounting body when the door is opened to the maximum opening angle. Obviously, , wherein as long as A meets a certain range, the calculated L2 can meet the requirement of no interference, for example, A is between 1-5 mm, and the calculated moving distance L2 can meet the requirement of no interference.

[0127] Similarly, the above formula of d and the maximum opening angle of the door body assembly does not constitute a limitation, for example, the above calculation formula can also have a correction coefficient or a correction parameter. In addition, the above calculation formula is determined for the hinge shaft center 101, if the box door 2 is installed by using a double shaft hinge 10 or a movable hinge 10, the hinge shaft center 101 will change with the opening of the box door 2, and the moving distance of the hinge shaft center 101 needs to be calculated in the formula.

[0128] According to the embodiments of the present application, the maximum opening angle of the door body assembly is 90°-145°, and the moving distance d of the door panel is between 14.15 mm and 109.108 mm. Among them, the maximum opening angle and the minimum value of the moving distance d are positively correlated, that is, the greater the maximum opening angle, the greater the minimum value of the corresponding moving distance d. For example, when the maximum opening angle is 96°, the minimum value of the moving distance d is 15.233 mm to 66.616 mm; and when the maximum opening angle is 145°, the minimum value of the moving distance d required is 67.883 mm to 109.108 mm.

[0129] According to the embodiments of the present application, when the maximum door opening angle is 90°-145°, and the minimum value of the corresponding moving distance d is between 14.15 mm and 109.108 mm, the door plate can be further guaranteed not to interfere, and based on the minimum value of the moving distance, the design reference standard of the sliding mechanism can be ensured to improve the user experience of the door body assembly.

[0130] According to the embodiments of the present application, in order to meet the use requirements of the refrigeration equipment, and to keep the style uniform between the refrigeration equipment and the installation body, in combination with Figure 2 , the thickness D1 of the door plate is generally 12 mm-25 mm, and the thickness D2 of the box door is generally 20 mm-60 mm. Of course, the numerical range herein does not constitute a limitation on the embodiments of the present application.

[0131] According to the embodiments of the present application, in order to further guarantee the use safety of the door body assembly, the door plate 21 at the maximum door opening angle, in combination with Figure 2 , the safety gap A between the interference position of the door plate 21 and the panel of the installation body is 1 mm-5 mm, and the interference position refers to the position of the hinge side of the door plate 21 that is most likely to interfere, which corresponds to the outside corner of the hinge side of the door plate 21. Of course, the gap between the interference position and the panel of the installation body can also be infinitely close to zero, so that the interference between the interference position and the panel of the installation body is just guaranteed. The gap between the interference position and the panel of the installation body is not limited by the examples herein. In addition, in order to facilitate the assembly of the door body assembly, the assembly gap B between the door plate and the box door can be 1 mm-10 mm, and the assembly gap C between the box door and the refrigeration cabinet can be 3 mm-15 mm. Similarly, the examples herein do not constitute a limitation on the door body assembly.

[0132] In combination with the following table, the safety gap A can be selected as 1 mm, 3 mm, 4 mm, the assembly gap B can be selected as 1 mm, 2 mm, 5.6 mm, 10 mm, the assembly gap C can be selected as 3 mm, 4 mm, 8 mm, 10.5 mm, 10 mm, the thickness of the door plate can be selected as 12 mm, 18 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, the thickness of the box door can be selected as 20 mm, 23 mm, 33 mm, 38 mm, 40 mm, 45 mm, 47 mm, 52 mm, 60 mm, and the distance from the bottom of the box door 2 to the refrigeration cabinet 1 at the maximum door opening angle can be 35.85 mm, 20 mm, 30 mm. On this basis, different minimum moving distances can be obtained corresponding to different maximum door opening angles, please refer to the following table.

[0135]

[0136] Table 3

[0137]

[0138] Table 4

[0139] The data with gray background in Table 3 above is the preferred data, that is, the data corresponding to the safety gap A of 3 mm, the assembly gap B of 2 mm, the gap C of 8 mm, the door plate thickness D1 of 18 mm, the cabinet door thickness D2 of 23 mm to 60 mm, the size E of 30 mm, and the maximum door opening angle of 96° to 145°. Correspondingly, the value of L2 is 24.133 mm to 67.883 mm.

[0140] According to the embodiments of the present application, in order to ensure the opening of the door body assembly, in addition to preventing the interference of the door plate 21 with the outer surface of the second cabinet plate 602, it is also necessary to ensure that the interference site of the door plate 21 does not interfere with the inner surface of the accommodation space. In combination with Figures 6 to 8 , the distance between the end surface of the hinge side of the door plate 21 and the corresponding side wall of the accommodation space is , greater than the movement distance γ of the interference site along the width direction of the accommodation space before the interference site leaves the accommodation space, so as to prevent interference.

[0141] The door plate 21 has a first interference site c point and a second interference site c o point (the interference site mentioned above is the second interference site c o point here), the first interference site is located at the inner corner of the door opening side of the door plate 21, and the second interference site is located at the outer corner of the hinge side of the door plate 21. The "inner" and "outer" are relative to the refrigeration cabinet 1, the side facing the refrigeration cabinet 1 is the "inner" side, and the side away from the refrigeration cabinet 1 is the "outer" side. Since Figures 6 to 8 is a top view, the first interference site and the second interference site are a point from the figure, and it can be understood that for the door body assembly, the first interference site and the second interference site are a vertical line respectively. If the inner corner of the door opening side is in an arc shape, the first interference site at this time is the point on the arc segment farthest from the hinge shaft center 101 of the cabinet door 2. Similarly, if the outer corner of the hinge side of the door plate 21 is in an arc shape, the second interference site at this time is the point on the arc segment farthest from the hinge shaft center 101 of the cabinet door 2.

[0142] When the cabinet door 2 is closed, the distance between the end surface of the door opening side of the door plate 21 and the corresponding side wall of the accommodation space is , and the distance between the end surface of the hinge side of the door plate 21 and the corresponding side wall of the accommodation space is . Among them, The distance γ is greater than the distance γ that the first interference position moves along the width direction of the receiving space before leaving the receiving space. γ is the vertical distance that the first interference position moves toward the side wall of the corresponding receiving space. The distance λ is greater than the distance the second interference position moves along the width direction of the receiving space before leaving it, where λ is the vertical distance the second interference position moves towards the side wall of the corresponding receiving space. Specifically, when the door 2 is in the closed position, the width direction of the door 2 is consistent with the width direction of the receiving space. As the door 2 opens, the width direction of the door 2 forms an angle with the width direction of the receiving space.

[0143] According to an embodiment of this application, the positions on the door panel 21 most prone to interference are firstly determined to be 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 also determined. Based on this, the conditions that must be met for the first interference position to prevent interference and the conditions that must be met for the second interference position to prevent interference are determined, thereby determining the initial gap on both sides of the door assembly. and The movement between the door panel 21 and the door panel 21 must meet certain rules to ensure the normal operation of the embedded refrigeration equipment.

[0144] Among them, combined Figures 6 to 8 , The angle of rotation during the opening of door 2 is shown. The relationship between the position (indicated by the dotted line in the diagram) and angle of the refrigeration equipment (refrigerator) when initially closed and when door 2 is opened to any angle is simplified and annotated. Corners where interference may occur during the opening process are marked with black dots in the diagram. The first interference point, c, is prone to interference with point e1 on the outer right side of the first cabinet panel 601601. That is, point e1 is the critical point where point c escapes interference (leaves the storage space) during the opening and closing process. The second interference point c... o Point c is the outer corner point on the right side of door panel 21. It is the corner point where the right end face of door panel 21 first interferes with the left end face of the adjacent second cabinet panel 602 during the opening and closing process. As can be seen from the diagram, in the initial position, on the left side of hinge axis 101, the angle between the hypotenuse oc (point c) and the inner side of door panel 21 is θ0. The angle when the door 2 is opened to any position is... At that position, the hypotenuse oc is at a distance of and distance Indicated by dashed lines; in the initial position, on the right side of hinge axis 101, c o The hypotenuse between point 101 and hinge axis 101 is oc. o When the door 2 is opened to any position, the angle is At that time, the hypotenuse c at that position o ,distance The distance l3 is represented by a dashed line; as can be seen from the figure, during the opening process of the door 2, if the door panel 21 does not move along the door 2 towards the opening side, as the opening angle increases, then c o The point 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 of the door, it is necessary to ensure that during the opening process, when the door is open at an angle of... At that time, the corresponding door panel 21 moves a distance d towards the opening side.

[0145] Based on the above, and under the premise of ensuring that the door components do not interfere with each other, in order to guarantee the aesthetics and safety of the embedded cooling equipment, as mentioned earlier, the initial gap on both sides of the door panel 21 generally does not exceed 5mm. This application further provides... The upper limit. Specifically, the spacing. satisfy: .

[0146] Among them, combined Figures 6 to 8 λmax is zero and γ is zero for The value of λ corresponding to time, When the first interference position leaves the containment space The value of γ is given by γ, where γ is zero, representing the initial gap on the opening side of door panel 21. It can be zero or infinitely close to zero. In this case, when for At that time, the displacement of the hinge side of the door panel 21 is λmax. In order to ensure that the hinge side of the door panel 21 does not interfere with the second cabinet panel 602, the λmax of the hinge side of the corresponding door panel 21 is the maximum required λmax.

[0147] Based on the embodiments of this application, it can be understood that 、 as well as The larger the value, the more necessary it is to prevent interference. The bigger, that is, 、 as well as Equal Positive correlation It is negatively correlated with the maximum d before the interference site leaves the containment space. The vertical distance from the hinge axis 101 of the door 2 to the inner surface of the door panel 21 is denoted as . The vertical distance from the hinge axis 101 of the door 2 to the hinge side end face of the door panel 21 is denoted as . d is the thickness of the door panel 21, and d is the distance that the door panel 21 moves relative to the door 2 during the opening process.

[0148] In one embodiment, the distance satisfies: .

[0149] wherein, , .

[0150] Similarly, the above calculation formula does not constitute a limitation on , for example, the above calculation formula can also have a correction coefficient or a correction parameter. In addition, the above calculation formula is determined for the case of the hinge axis 101, if the cabinet door 2 is installed with a double shaft hinge 10 or a movable hinge 10, the hinge axis 101 will change with the opening of the cabinet door 2, and at this time The calculation formula of is also adaptively changed, and the moving distance of the hinge axis 101 needs to be calculated in the formula. In addition, if there is a mounting gap between the door plate 21 and the cabinet door 2, at this time 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,

[0151] According to the embodiment of the present application, the sliding door mechanism 7 comprises a sliding mechanism and a traction mechanism.

[0152] According to one embodiment of the present application, please refer to Figures 9 to 10 , 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 plate 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 that 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 plate 21 to move relative to the width direction of the cabinet door 2.

[0153] It can be understood that the sliding mechanism of the 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 plate 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 slide relatively to drive the door plate 21 to slide relative to the cabinet door 2, so that the door plate 21 can avoid the obstacles on both sides during the opening and closing of the cabinet door 2.

[0154] 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, enabling the first slider 714 to 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.

[0155] 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, to drive the door panel 21 to avoid obstacles.

[0156] For example, during 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, while 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 avoiding interference between the door panel 21 and the obstacle outside. During 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, while 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, thereby avoiding interference between the door panel 21 and the obstacle after closing.

[0157] 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 its working process is the same as the above-mentioned embodiment, which will not be described here.

[0158] 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 is rotated, 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 process of opening and closing the cabinet door 2.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] In an embodiment of the present application, as Figure 10As 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.

[0167] 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.

[0168] 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.

[0169] Specifically, the second slider 713 and the first slider 714 are both provided with a connecting head 711 for fixing the flexible cable 706.

[0170] In one embodiment of the present application, as Figure 10As 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.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] In the embodiment, 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, the first fixed seat 701 is fixed in the external structure, so as to fix the sliding mechanism on the external structure (such as the box door 2). At the same time, the second adjusting member 703 can be finely adjusted in the position along the second waist-shaped hole, so as to adjust the position of the first fixed seat 701, thereby being able to adjust the position of the first fixed seat 701 relative to the external structure.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] In an embodiment of the present application, as shown in Figure 10 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.

[0185] 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 the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 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.

[0186] 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.

[0187] In another aspect of an embodiment of the present application, as shown in Figure 9As shown, a door body assembly is provided, comprising a cabinet door 2, a door panel 21 and a sliding mechanism as provided in any of the above embodiments. The cabinet door 2 is rotatably connected to the cabinet 1 and is adapted to open or close the storage space of the cabinet 1. The door panel 21 is slidably arranged on the outside of the cabinet door 2. The sliding mechanism is arranged on the cabinet door 2, the first sliding block 714 is adapted to be drivingly connected to the cabinet 1, and the second sliding block 713 is connected to the door panel 21. During the opening or closing of the cabinet door 2, the first sliding block 714 and the second sliding block 713 move in opposite directions to drive the door panel 21 to move relative to the cabinet door 2.

[0188] Specifically, during the opening of the cabinet door 2 to the outside of the cabinet 1, the first sliding block 714 is driven by the traction mechanism to slide towards the first hinge 4 under the drive of the cabinet 1, and the first sliding block 714 drives the second sliding block 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 the obstacle outside. Similarly, during the closing of the cabinet door 2 to the side of the cabinet 1, the sliding mechanism drives the door panel 21 to slide towards the first hinge 4, thereby avoiding interference between the door panel 21 and the obstacle after closing.

[0189] According to the door body assembly of the present application, the sliding mechanism is arranged on the cabinet door 2 and connected to the cabinet door 2 and the door panel 21, respectively, to drive the door panel 21 to slide relative to the width direction of the cabinet door 2 during the opening or closing of the cabinet door 2 relative to the cabinet 1, so that the door panel 21 can avoid obstacles such as walls or objects on the side during the closing or opening of the cabinet door 2.

[0190] It can be understood that the sliding mechanism has the beneficial effects of the above embodiments, and the door body assembly accordingly has the beneficial effects of the above embodiments, and the specific embodiments can be referred to the above embodiments, which will not be described herein.

[0191] In an embodiment of the present application, as shown in Figures 10 to 11 The first connecting block 712 is provided on the second sliding block 713, and the insertion slot is formed on the first connecting block 712 for the door panel 21 to be hung.

[0192] In the present embodiment, the first connecting block 712 is arranged on the second sliding block 713, and the insertion slot is arranged on the first connecting block 712. Correspondingly, the door panel 21 is provided with a connecting assembly (such as a hook, a plug, etc.) adapted to the insertion slot, so as to mount the door panel 21 on the first connecting block 712, so that the door panel 21 can slide with the second sliding block 713. At the same time, it is also convenient for the user to dismount the door panel 21 from the second sliding block 713 when needed, so as to meet the use requirements of the user in different scenarios.

[0193] 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 13 to 15 . The sliding mechanism includes a guide member 730, a sliding member 740, a linkage assembly 750, and a driving rod 760.

[0194] The guide member 730 is configured to be arranged on the cabinet door, and the guide member 730 is provided with a guide structure 731. The sliding member 740 is configured to be arranged on the door panel, and the sliding member 740 is movably arranged on the guide member 730 along the width direction of the cabinet door.

[0195] The linkage assembly 750 is movably arranged 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.

[0196] The driving rod 760 is arranged 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.

[0197] 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 arranged on the hinge shaft, so as to realize the opening or closing of the cabinet door relative to the cabinet.

[0198] 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.

[0199] 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.

[0200] 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.

[0201] Optionally, the linkage assembly 750 can be a parallel four-bar linkage mechanism, or a crank rocker mechanism.

[0202] For the sliding mechanism shown in the embodiment, the guide 730 is arranged on the cabinet door, the sliding piece 740 is arranged on the door panel, the sliding piece 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 piece 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 piece 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 piece 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.

[0203] In some embodiments, as shown in Figure 13 The link assembly 750 includes a first link 751 and a second link 752.

[0204] 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 piece 740.

[0205] 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 piece 740 to move in the direction opposite to the driving direction of the driving rod 760.

[0206] 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.

[0207] In the process of opening the cabinet by the cabinet door, the driving rod 760 drives the first end of the first connecting rod 751 to move along the width direction towards the side close to the hinge, the first connecting rod 751 drives the first hinge shaft 753 to move along the thickness direction towards the side close to the sliding piece 740, the included angle between the first connecting rod 751 and the second connecting rod 752 is increased, the second connecting rod 752 is pushed to move towards the side away from the hinge, and the sliding piece 740 is further driven to move along the width direction towards the side away from the hinge, so that the door plate is prevented from interfering with the cabinet.

[0208] In the process of closing the cabinet by the cabinet door, the driving rod 760 drives the first end of the first connecting rod 751 to move along the width direction towards the side away from the hinge, the first connecting rod 751 drives the first hinge shaft 753 to move along the thickness direction towards the side away from the sliding piece 740, the included angle between the first connecting rod 751 and the second connecting rod 752 is decreased, the second connecting rod 752 is pushed to move towards the side close to the hinge, and the sliding piece 740 is further driven to move along the width direction towards the side close to the hinge, so that the door plate is restored to the original position and interference between the door plate and the cabinet around the refrigeration equipment is prevented.

[0209] The embodiment achieves the movement of the door plate relative to the cabinet door by setting the first connecting rod 751, the second connecting rod 752 and the first hinge shaft 753 in the connecting rod assembly 750, changing the included angle between the first connecting rod 751 and the second connecting rod 752 by limiting the movement of the first hinge shaft 753 along the thickness direction, and driving the sliding piece 740 to move along the width direction by the second connecting rod 752, so that the structure is simple and the volume is small.

[0210] In some embodiments, as shown in Figure 13 The driving rod 760 includes a connecting piece.

[0211] The first end of the connecting piece is configured to be rotatably arranged at a fixed position on the cabinet of the refrigeration equipment, and the second end of the connecting piece is rotatably connected with the first end of the first connecting rod 751; the fixed position is arranged away from the hinge position between the cabinet door and the cabinet.

[0212] In the process of opening the cabinet by the cabinet door, the connecting piece is used to drive the first end of the first connecting rod 751 to move towards the side close to the hinge position, and the second connecting rod 752 drives the sliding piece 740 to drive the door plate to move towards the side away from the hinge position.

[0213] In the process of closing the cabinet by the cabinet door, the connecting piece is used to drive the first end of the first connecting rod 751 to move towards the side away from the hinge position, and the second connecting rod 752 drives the sliding piece 740 to drive the door plate to move towards the side close to the hinge position.

[0214] 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.

[0215] 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.

[0216] 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.

[0217] 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.

[0218] In some embodiments, as shown in FIG. 7A, the guide structure 731 includes a first limiting slot 7311. Figure 14

[0219] The first limiting slot 7311 extends along the thickness direction.

[0220] 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.

[0221] 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.

[0222] ​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.

[0223] In some embodiments, as shown in Figure 14 The guide structure 731 further includes a second limiting groove 7312.

[0224] The second limiting groove 7312 extends along the width direction and is in communication with the first limiting groove 7311.

[0225] 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.

[0226] The second hinged shaft 754 and the third hinged shaft 755 are respectively arranged on the two sides of the first limiting groove 7311.

[0227] 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.

[0228] In some embodiments, as shown in Figure 13 The sliding mechanism further includes an elastic piece 770.

[0229] The elastic piece 770 is arranged between the guide piece 730 and the sliding piece 740.

[0230] 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.

[0231] 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.

[0232] 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.

[0233] 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.

[0234] 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.

[0235] Specifically, the elastic piece 770 can be an elastic sheet, an elastic block, or a spring.

[0236] 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.

[0237] In some embodiments, as shown in Figures 13 to 15 The guide piece 730 includes a fixed plate 732 and a sliding groove 733.

[0238] The fixed plate 732 is configured to be arranged on the cabinet door.

[0239] 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.

[0240] 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.

[0241] In some embodiments, as shown in Figure 14 and Figure 15 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.

[0242] 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.

[0243] The elastic piece 770 is arranged between the sliding sleeve 734 and the sliding contact 745.

[0244] 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.

[0245] 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.

[0246] In some embodiments, as shown in Figure 13 the elastic piece 770 includes a spring, the spring is sleeved on the outer side of the guide rod 741 and is limited between the sliding sleeve 734 and the sliding contact 745.

[0247] It can be understood that when the elastic piece 770 is arranged as a spring, the hollow structure of the spring enables the spring to be sleeved on the outer wall of the guide rod 741, and in the length direction of the guide rod 741, the 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.

[0248] In some embodiments, as shown in Figure 13 and Figure 14 the sliding piece 740 further includes a first connecting arm 743 and a second connecting arm 744.

[0249] The first connecting arm 743 and the second connecting arm 744 are arranged in the width direction, 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.

[0250] The sliding sleeve 734 and the sliding contact 745 are located between the first connecting arm 743 and the second connecting arm 744.

[0251] 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.

[0252] 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.

[0253] 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.

[0254] In an embodiment of the present application, Figure 9 、 Figure 16 and Figure 17 As shown in the figure, the door body assembly further comprises a first driven guide rail mechanism 8. The first driven guide rail mechanism 8 is arranged in parallel with the sliding mechanism on the cabinet door 2 and comprises a second base 817 and a third sliding block 813. The second base 817 is formed with a third guide rail, and the third sliding block 813 is slidably arranged on the third guide rail. 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.

[0255] In the embodiment, the first driven guide rail mechanism 8 is arranged in parallel with the sliding mechanism on the cabinet door 2, the first driven guide rail mechanism 8 has a second base 817, the second base 817 is provided with a third guide rail and a third sliding block 813 which can slide along the third guide rail, and the third sliding block 813 is connected with the door panel 21 through the second connecting block 812. 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.
