Description

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 be seamlessly embedded in the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, although the embedded refrigerator exhibits significant advantages in improving the aesthetics and space utilization of the home, it still has a problem that cannot be ignored in actual use: the door is prone to interference or collision with the cabinet side wall during opening, resulting in poor user experience of the embedded refrigerator. SUMMARY

[0092] In today's society, the rapid progress of technology has greatly promoted the transformation of home living style. Among them, the embedded furniture, as a design concept that combines aesthetics and practicality, is favored by the majority of consumers. Embedded furniture cleverly integrates appliances or storage space into the home environment, not only effectively saving space, but also significantly improving the overall coordination and aesthetics of the home. Taking 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 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 body is prone to interference or collision with the cabinet side wall during opening, resulting in poor user experience of the embedded refrigerator.

[0093] Specifically, the embedded refrigerator (referred to as refrigerator) meets the user's demand for two different refrigerator use requirements of pure flat full embedding and full embedding. After the refrigerator door body (referred to as door body) is connected with the cabinet door panel (referred to as door panel), the entire door body assembly is thickened, causing the door body assembly with the cabinet door to interfere with the cabinet during opening and closing, resulting in failure to open and use normally. Therefore, combined with the above problems, the present application provides a refrigerator door body assembly and a refrigerator. Figure 1The present application provides a door body assembly capable of relative sliding between the door and the door panel, so that the door panel can slide towards the opening side of the door during the opening process of the door body assembly, so that the hinge 10 side still maintains the thickness of the door 2 itself during the opening process, consistent with the opening scenario without the door panel 21. During the closing process, the door panel 21 will move towards the hinge 10 side to return to the state before opening, thereby realizing the refrigerator embedded installation requirement with and without the door panel 21.

[0094] If the movement amplitude of the door panel 21 relative to the door 2 is too large, not only the interference prevention effect cannot be achieved, but also the use space is increased, which makes the user panic and worry about the door panel 21 falling off, and the noise also brings trouble to the user, thereby reducing the user experience.

[0095] Based on this, the present application further provides a door body assembly of an embedded refrigeration equipment, please refer to Figure 1 and Figure 2 , comprising: a door 2 and a door panel 21. The door 2 is rotatably connected to a refrigeration cabinet 1, wherein the refrigeration cabinet 1 is used to be embedded into the accommodating space formed by the installation body. Wherein, the refrigeration cabinet 1 is used to be embedded into the accommodating space formed by the installation body. The installation body generally refers to the cabinet 60, of course, the installation body can also be a wall corner, or the installation body can also refer to other components, as long as it can form an accommodating space, hereinafter the installation body is taken as the cabinet 60 as an example for description. 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. During the opening process of the door 2, the door panel 21 is adapted to move towards the opening side of the door 2, and the moving distance is . The door panel 21 has a first interference point c and a second interference point d. The first interference point is located at the inner corner of the opening side of the door panel 21, and the second interference point is located at the outer corner of the hinge 10 side of the door panel 21. Wherein, the first interference point is the position of the opening side of the door panel that is most likely to interfere, and the second interference point is the position of the hinge side of the door panel that is most likely to interfere, and the positions of the first interference point and the second interference point on the door panel 21 are determined. In addition, the above "inner" and "outer" are relative to the refrigeration cabinet 1, the side towards the refrigeration cabinet 1 is the "inner" side, and the side away from the refrigeration cabinet 1 is the "outer" side. Since Figure 2 is a top view, the first interference point and the second interference point are a point in Figure 2 , it can be understood that for the door body assembly, the first interference point and the second interference point are a vertical line respectively. Wherein, if the inner corner of the opening side is in a circular arc shape, the first interference point at this time is the point on the arc segment farthest from the hinge shaft 101 of the door 2. Similarly, if the outer corner of the hinge 10 side of the door panel 21 is in a circular arc shape, the second interference point at this time is the point on the arc segment farthest from the hinge shaft 101 of the door 2.

[0096] According to the embodiments of the present application, in combination with Figure 2 and Figure 3 , the gap Z between the second interference position and the side wall of the accommodating space is not greater than a first set value before the second interference position leaves the accommodating space. Before the second interference position leaves the accommodating space, there is a possibility of interference between the second interference position and the side wall of the accommodating space. The embodiments of the present application ensure that the gap between the second interference position and the side wall is not greater than the first set value on the basis of ensuring that the second interference position and the side wall of the accommodating space do not interfere, thereby preventing the movement amplitude of the door panel 21 from being too large, ensuring that the sliding of the door panel 21 gradually changes as the opening angle of the door increases, rather than the door panel 21 directly moving to the position in one step in the case where the movement amplitude required at a certain opening angle of the door is small itself, thereby improving the stability of the door body assembly and reducing the user's panic about the large movement of the door panel 21, thereby improving the user experience. Especially after the first interference position of the door panel 21 leaves the accommodating space, at this time the door panel 21 is closer to the user, thereby ensuring that the distance between the second interference position and the side wall of the accommodating space is not too large during this process, which can improve the user experience. The first set value and the second set value are not limited and only need to be small values that ensure that the distance between the door panel and the mounting body is not too far.

[0097] According to the embodiments of the present application, as the opening angle of the door body assembly gradually increases, the second interference position may eventually leave the accommodating space. Among them, after the second interference position leaves the accommodating space, the second interference position gradually moves towards the outer surface of the second cabinet panel 602, and eventually the second interference position may interfere with the outer surface of the second cabinet panel 602. The embodiments of the present application, in combination with Figure 1 to Figure 3 , after the second interference position leaves the accommodating space, the gap between the second interference position and the panel of the mounting body is not greater than a second set value, to further ensure the structural stability of the door body assembly and avoid the user's panic about the door panel 21 falling off.

[0098] According to the embodiments of the present application, in order to meet the condition that the door panel 21 does not move, there are various movement schemes of the door panel 21, including the case where the door panel 21 moves a large distance at certain opening angles of the door and does not move at other opening angles of the door. The embodiments of the present application correspond to Figure 2 and Figure 3 , the change value of the movement distance does not exceed a set displacement, thereby ensuring that the movement of the door panel 21 is relatively concealed and not easily perceived, avoiding the user's intuitive feeling about the movement of the door panel 21. Moreover, since the displacement of the door panel 21 at each set angle does not exceed the set displacement, it can avoid the knocking that may be caused by the sudden large movement of the door panel 21, thereby ensuring the safety of the user.

[0099] According to the embodiments of the present application, the smaller the set angle is, the more precise the control of the door panel 21 during the opening process of the door body assembly is, and the moving distance of the door panel 21 corresponding to each opening angle is obtained through small-angle opening control, and then the optimal door body assembly structure is obtained. For example, the set angle is 0.5° before the first interference position leaves the containing space. Of course, the set angle can also be other values before the first interference position leaves the containing space. In addition, the set angle is 1° after the first interference position leaves the containing space. Similarly, the set angle can also be other values after the first interference position leaves the containing space. Among them, the set angle after the first interference position leaves the containing space can be greater than the set angle before the first interference position leaves the containing space, and then more precise control of the door body assembly can be achieved for the stage before the first interference position leaves the containing space, which is more prone to interference. Of course, the set angle after the first interference position leaves the containing space can also be equal to the set angle before the first interference position leaves the containing space.

[0100] According to the embodiments of the present application, the angle θ of the first interference position of the door panel 21 leaving the containing space is calculated, and small-angle calculation is performed within the angle range from zero degree to angle θ of the opening angle, and the moving distance of the door panel 21 is calculated every 0.5°, and it is respectively judged whether the component of the moving distance in the width direction of the containing space exceeds the initial gap corresponding to the first cabinet panel 601 and the second cabinet panel 602 and . Then, within the opening angle range of θ~90°, small-angle calculation is again used, for example, the moving distance is calculated every 1°, and the moving distance at this time not only needs to meet the requirement of not exceeding the initial gap , but also cannot be too large. From 0° to 90°, a moving distance can be updated every 0.5°, and if the moving distance obtained through model simulation (the model of the sliding mechanism between the door panel 21 and the cabinet door 2, the sliding mechanism is used to connect the door panel 21 and the cabinet door 2, so that the door panel 21 moves relative to the cabinet door 2 under the action of the sliding mechanism, which will be introduced later) meets the above requirements for subsequent opening, the parameters can be fixed, and if the moving distance range at a certain angle is too large, the current model needs to be updated, and then the moving distance at each opening angle is recalculated based on a brand-new model. Only when the sliding distances at all angles meet the requirements, the sliding mechanism can be designed based on the current model.

[0101] According to the embodiments of the present application, as long as the optimal moving distance at each opening angle is found out step by step in small-angle stages in order to control the displacement in a way that neither interferes nor wastes displacement, the data derivation method is not limited, and all are within the protection scope of the present patent.

[0102] According to the embodiments of the present application, the opening angle of the door body assembly and the sliding distance of the door panel 21 is positive, and the change value of the sliding distance of the door panel 21 per interval set angle is within a set range . Since the change value of the sliding distance of the door panel 21 per interval set angle is within a set range , it can be ensured that the sliding distance of the door panel 21 is as uniform as possible or close to uniform during the entire opening process, or even if the sliding distance cannot be uniform, there will be no obvious mutation, so as to ensure that the sliding of the door panel 21 is as secret as possible and not easy to be found, reduce the noise of the door panel 21, and improve the user experience. And because the movement of the door panel 21 is relatively smooth, it can avoid interference. And since the change value of the sliding distance of the door panel 21 per interval set angle is within a set range , it can save space and find the minimum sliding distance required.

[0103] According to an embodiment of the present application, the set angle is 0.5°, and the set range is 0.193 mm to 0.45 mm. At this time, the opening angle of the cabinet door 2 assembly is analyzed at a small angle. Since the sliding distance per 0.5° must meet the set condition, that is, the change value of the sliding distance is 0.193 mm to 0.45 mm, the requirement for the sliding mechanism is relatively strict, and the corresponding sliding mechanism can maximize the user experience. Alternatively, the opening angle can be divided. Before the opening side of the door panel 21 leaves the containing space, the set angle can be 0.5° to ensure that the door panel 21 does not interfere with the side wall of the containing space, including the first cabinet panel 601 and the second cabinet panel 602. After the opening side of the door panel 21 leaves the containing space, the set angle can be larger than before, for example, it can be 1°, so as to obtain more sliding mechanisms that meet the requirements.

[0104] In one embodiment, the relationship between the sliding distance and the door opening degree (i.e. the opening angle) is as follows:

[0105]

[0106] Table 1

[0107] In another embodiment, under the condition that other parameters remain unchanged or are slightly adjusted, the relationship between the sliding distance and the door opening degree (i.e. the opening angle) is as follows:

[0108]

[0109] Table 2

[0110] It should be noted that the units of the relevant distance parameters are millimeters without limitation.

[0111] In combination with Table 1, when the door body assembly has an opening angle of 0.5°, the sliding distance is 0.37-0.47 mm. In addition, when the door body assembly has an opening angle of 90°, the sliding distance is 62.95-63.04 mm.

[0112] In combination with Table 1 and Figure 37 The traction mechanism includes a traction rod, which is hinged by the first pin shaft and the sliding mechanism, and hinged by the second pin shaft and the box body. The distance between the second pin shaft and the end face of the hinge side of the box door 2 is L1, the distance between the hinge axis of the box door 2 and the end face of the hinge side of the box door 2 is L2, the distance between the second pin shaft and the hinge axis of the box door 2 is L3, the distance between the first pin shaft and the hinge axis of the box door 2 in the thickness direction of the box door 2 is L4, the straight line distance between the first pin shaft and the second pin shaft is L5, the included angle between the L5 corresponding straight line and the L3 corresponding straight line is The included angle between the L5 corresponding straight line and the width direction of the accommodation space is L1 is 30-40 mm, L2 is 7-15 mm, L3 is 40-55 mm, L4 is 10-20 mm, L5 is 0.2-0.4 mm, 20°-105.68°, 15°-18°. In an embodiment, referring to Table 1, L1 is 36.29 mm, L2 is 10.81 mm, L3 is 47.85 mm, L4 is 16.89, L5 is 0.288 mm, 20°-105.68°, 16.5°. In addition, the above values are mainly combined with product requirements and can be appropriately floated, for example, L2 is between 7 mm and 15 mm, which can meet the installation requirements and can ensure the structural strength.

[0113] From the above data, the following relationship can be fitted:

[0114] .

[0115] The fitting relationship is based on the double sliding rail and double sliding block sliding mechanism provided in the subsequent embodiments.

[0116] According to the embodiments of the present application, the sliding mechanism and the traction mechanism function to enable the door panel 21 to move relative to the cabinet door 2. It is obvious that the specific structural forms of both are not limited. For example, the sliding mechanism can adopt the structural form of the double sliding blocks mentioned below, the structural form of the connecting rod, the structural form of the gear and rack, etc. Correspondingly, the traction mechanism can adopt the structural form of the traction rod, the direct driving mode of the air cylinder or the hydraulic cylinder, etc.

[0117] In combination with Figure 2 and Figure 3 , the distance between the end face of the door panel 21 on the opening side and the side wall of the accommodating space corresponding thereto when the cabinet door 2 is closed is , and the distance between the end face of the door panel 21 on the hinge side and the side wall of the accommodating space corresponding thereto is . Among them, is greater than the movement distance γ of the first interference site along the width direction of the accommodating space before the first interference site leaves the accommodating space, and γ is also the vertical distance of the movement of the first interference site towards the side wall of the corresponding accommodating space. is greater than the movement distance λ of the second interference site along the width direction of the accommodating space before the second interference site leaves the accommodating space, and λ is also the vertical distance of the movement of the second interference site towards the side wall of the corresponding accommodating space. Among them, when the cabinet door 2 is in the closed position, the width direction of the cabinet door 2 is consistent with the width direction of the accommodating space. With the opening of the cabinet door 2, the width direction of the cabinet door 2 and the width direction of the accommodating space form an angle at this time.

[0118] According to the embodiments of the present application, the conditions to be met to determine that the first interference site does not interfere, and the conditions to be met to determine that the second interference site does not interfere, thereby determining the regularity to be met between the initial gap (g1 and g2) and 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 equipment.

[0119] On the basis of the above, under the premise of meeting the non-interference of the door body assembly, in order to ensure the aesthetics and use safety of the embedded refrigeration equipment, as mentioned above, the initial gap (g1 and g2) and on both sides of the door panel 21 generally does not exceed 5 mm. Thus, on the basis of the determination of the initial gap (g1 and g2) and , while meeting the above-mentioned gap between the second interference site and the side wall of the corresponding accommodating space not exceeding the first set value, or the gap between the second interference site and the outer surface of the mounting body not exceeding the second set value, the corresponding required movement distance (δ1 and δ2) can be obtained.

[0120] In combination with Figure 2 andFigure 3 , the hinge axis 101 of the cabinet door 2 corresponds to the point o in the figure, is the vertical distance from the hinge axis 101 of the cabinet door 2 to the inner surface of the door panel 21, is the vertical distance from the hinge axis 101 of the cabinet door 2 to the end surface of the door panel 21 on the door opening side, is the vertical distance from the hinge axis 101 of the cabinet door 2 to the end surface of the door panel 21 on the hinge side, is the thickness of the door panel 21, is the distance that the door panel 21 moves relative to the cabinet door 2 during opening of the cabinet door 2.

[0121] Figure 2 and Figure 3 In the above, the relationship and angle relationship of the position of the refrigeration device (refrigerator) when the cabinet door 2 is initially not opened and when the cabinet door 2 is opened to any angle (indicated by the dashed line in the figure) are assumed to be simplified and described. In the figure, the corners that can interfere during opening of the door are marked with black dots, wherein the first interference site c point is prone to interference with the e point on the outer side of the right end of the first cabinet panel 601, that is, the e point is the critical point at which the c point escapes from interference (leaves the accommodation space) during opening and closing of the door, and the second interference site d point is the corner point on the outer side of the right end of the door panel 21, which is the corner point at which the right end surface of the door panel 21 first interferes with the left end surface of the second cabinet panel 602 adjacent to the right side during opening and closing of the door. As can be seen from the figure, at the initial position, the included angle between the oblique side oc between the c point and the hinge axis 101 (o point) on the left side of the hinge axis 101 and the inner side of the door panel is θ0, and the angle of the cabinet door 2 when opened to any position is , the oblique side oc at this position is at a distance and a distance indicated by the dashed line; at the initial position, the oblique side od between the d point and the hinge axis 101 on the right side of the hinge axis 101, when the cabinet door 2 is opened to any position, is at an angle of , the oblique side od at this position is at a distance +h and a distance l3 indicated by the dashed line; as can be seen from the figure, if the door panel does not move towards the door opening side during opening of the cabinet door 2, the d point will soon interfere with the left end surface of the second cabinet panel 602 as the opening angle increases, resulting in the cabinet door 2 being unable to open, and therefore, in order to avoid interference affecting opening of the door, when the door body is opened to an angle of , the corresponding door panel 21 moves towards the door opening side by a distance .

[0122] According to the embodiments of the present application, it can be understood that , , The greater the distance, the more likely the door panel 21 will interfere at this time, thereby, , , and are positively correlated. In addition, and the maximum distance between the first interference site and the containing space before the door panel 21 moves away from the containing space are positively correlated, that is, when the first interference site moves away from the containing space, the distance that the door panel 21 moves relative to the cabinet door 2 is greater, which means that the distance that the door panel 21 moves at this time is greater, in order to prevent the door panel 21 from colliding during movement. The greater the distance between the first interference site and the containing space before the door panel 21 moves away from the containing space , the less likely the hinge side of the door panel 21 will interfere at this time, that is, the smaller the distance that the door panel 21 can be designed to move at this time . are negatively correlated.

[0123] According to embodiments of the present application, it is assumed that the door panel 21 moves a distance after which the length of the side on which the point c is located and the hinge axis 101 (i.e., the point o) is a, and the angle between this side and the horizontal line in the figure is α. At this time, the length of the side on which the point d is located and the hinge axis 101 (i.e., the point o) is b, and the angle between this side and the horizontal line in the figure is β.

There are limitations; for example, the above calculation formula can also have correction coefficients or correction parameters.

[0134] According to the embodiment of the present application, the relative movement between the door panel 21 and the cabinet door 2 is determined by the sliding mechanism or the traction mechanism driving the movement of the sliding mechanism. In the case that the relative movement between the door panel 21 and the cabinet door 2 is determined by the sliding mechanism, once the moving amount is determined, the sliding mechanism is determined. Specifically, when the moving amount is determined, the traction mechanism is determined. According to the embodiment of the present application, the relative movement between the door panel 21 and the cabinet door 2 is determined by the sliding mechanism or the traction mechanism driving the movement of the sliding mechanism.

The function relationship between the moving amount and the traction mechanism can be determined. The required sliding mechanism or traction mechanism can be obtained based on the function relationship.

[0135] According to the embodiment of the present application, the sliding door mechanism 7 comprises the sliding mechanism and the traction mechanism.

[0136] According to one embodiment of the present application, referring to Figure 4 to Figure 5 , the sliding mechanism comprises a first base 717, a first sliding block 714, a second sliding block 713 and a flexible cable 706. The first base 717 is formed with a first guide rail on one side and a second guide rail on the other side. The first sliding block 714 is slidably arranged on the first guide rail, and the traction mechanism is rotatably connected between the cabinet 1 and the first sliding block 717. The second sliding block 713 is slidably arranged on the second guide rail and is used to be connected with the door panel 21. The flexible cable 706 is connected with the first sliding block 714 and the second sliding block 713 at both ends. In the case 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 panel 21 to move relative to the cabinet door 2 in the width direction.

[0137] 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 slidably connected with the door panel 21 arranged outside the cabinet door 2, so that when the cabinet door 2 rotates, the first sliding block 714 and the second sliding block 713 slide relatively to drive the door panel 21 to slide relative to the cabinet door 2, so that the door panel 21 can avoid the obstacles on both sides during the process of opening and closing the cabinet door 2.

[0138] Specifically, taking the case that the first sliding block 714 is connected with the cabinet 1 through the traction mechanism and the second sliding block 713 is connected with the door panel 21 as an example, the first base 717 of the embodiment can be arranged on the cabinet door 2. The both ends of the flexible cable 706 are connected with the first sliding block 714 and the second sliding block 713 respectively, so that the first sliding block 714 can drive the second sliding block 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.

[0139] 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.

[0140] For example, during the process of opening the box door 2 to the outside of the box body 1, the box door 1 drives the first slider 714 to slide towards the first hinge 4, and at the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e. away from the first hinge 4) through the flexible cable 706, so as to avoid interference between the door panel 21 and the obstacle outside. During the process of closing the box door 2 to the side of the box body 1, the box body 1 drives the first slider 714 to slide away from the first hinge 4, and at the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e. towards the first hinge 4) through the flexible cable 706, so as to avoid interference between the door panel 21 and the obstacle after closing.

[0141] It can be understood that the first slider 714 can also be connected with the door panel 21, and correspondingly, the second slider 713 is connected with the box door 2 or the box body 1 through the traction mechanism, and the working process is the same as the above-mentioned embodiment, which will not be described here.

[0142] According to the sliding mechanism of the present application, the first guide rail and the second guide rail are arranged on both sides of the first base 717, and the first slider 714 and the 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 along the guide rail under the transmission of the flexible cable 706, and the sliding direction is opposite, one of the first slider 714 and the second slider 713 is connected with the box door 2 or the box body 1 through the traction mechanism, and the other is connected with the door panel 21 arranged outside the box door 2, so that when the box door 2 rotates, the two sliders slide relatively to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid the obstacles on both sides during the process of opening and closing the box door 2.

[0143] It should be noted that in actual application, the design of the first slider 714 and the second slider 713 can be flexible and varied to adapt to different working scenes and performance requirements. They are not limited to specific shapes, sizes or materials, but can be customized and optimized according to specific needs.

[0144] From the material point of view, the first slider 714 and the second slider 713 can choose materials with 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.

[0145] 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 flat 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 flat 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.

[0146] In addition, in order to enhance the carrying capacity and stability of the sliders, reinforcing ribs, support plates or other auxiliary structures can also be added to the first slider 714 and the second slider 713. These structures can increase the rigidity and anti-deformation ability of the sliders, ensuring stable sliding performance when bearing the weight of the door panel 21 and external forces.

[0147] In the present 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.

[0148] 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 sliders and stable operation of the system. This tolerance range is usually determined according to design requirements, use environment and system precision.

[0149] It should be noted that in the present embodiment, parallel and vertical should not be strictly in the geometric sense, 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.

[0150] In one embodiment of the present application, as shown in Figure 5 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 the two ends are 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 the two ends are connected to the other end of the first slider 714 and the second slider 713, respectively.

[0151] In the embodiment, the first flexible cable is wound around one end of the first base 717 and connected with 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, 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. Meanwhile, the second flexible cable is wound around the other end of the first base 717 and connected with 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 the two ends of the first base 717 respectively, the second slider 713 can slide reversely with the first slider 714, and the door panel 21 can slide relative to the cabinet door 2 to avoid interference with obstacles and affect the opening and closing of the cabinet door 2.

[0152] 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, working environment and use requirements. For occasions requiring 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.

[0153] Specifically, the second slider 713 and the first slider 714 are both provided with a connecting head 711 for fixing the flexible cable 706.

[0154] In an embodiment of the present application, as shown in Figure 5 The sliding mechanism further includes a first fixing seat 701 and a second fixing seat 702. The first fixing seat 701 is connected to one end of the first base 717 and forms a first limiting groove. The two ends of the first limiting groove are in butt joint with one end of the first guide rail and the second guide rail, and a part of the first flexible cable is slidably arranged in the first limiting groove. The second fixing seat 702 is connected to the other end of the first base 717 and forms a second limiting groove. The two ends of the second limiting groove are in butt joint with the other end of the first guide rail and the second guide rail, and a part of the second flexible cable is slidably arranged in the second limiting groove.

[0156] 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 piece 704, the first adjusting piece 704 passes through the first fixed hole and is slidably arranged in the first waist-shaped hole, so as to adjust the tightness of the first flexible cable by adjusting the position of the first adjusting piece 704 in the first waist-shaped hole.

[0157] In the embodiment, the position of the first fixed seat 701 can be adjusted along the width direction of the first base 717 by adjusting the position of the first adjusting piece 704 in the first waist-shaped hole, so that the first fixed seat 701 can tighten or loosen the first flexible cable, thereby adjusting the tightness of the first flexible cable.

[0158] 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 two sides of the first base 717, and the first flexible cable and the second flexible cable are connected with two ends of the first sliding block 714 and the second sliding block 713, 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 to correspond to the tightness, and the second flexible cable is also adjusted to correspond to the tightness under the pulling of the first fixed seat 701 to the first flexible cable.

[0159] 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 piece 704, the first adjusting piece 704 passes through the first fixed hole and is slidably arranged in the first waist-shaped hole, so as to adjust the tightness of the second flexible cable by adjusting the position of the first adjusting piece 704 in the first waist-shaped hole.

[0160] In the embodiment, the position of the second fixed seat 702 can be adjusted along the width direction of the first base 717 by adjusting the position of the first adjusting piece 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.

[0161] 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 sliding block 714 and the second sliding block 713, 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 correspondingly adjusted in tightness, and the first flexible cable is also correspondingly adjusted in tightness under the pulling of the second flexible cable by the second fixed seat 702.

[0162] 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 through the position of the second adjusting member 703 in the second waist-shaped hole.

In the present embodiment, by abutting a part of the first flexible cable on the supporting bearing, the activity and the extension direction of the first flexible cable are adjusted, so as to facilitate the connection of the first flexible cable around the end of the first base 717 with the first sliding block 714 and the second sliding block 713.

[0166] It can be understood that the second limiting groove can also be provided with a rotatable support bearing; a portion of the second flexible cable abuts on the support bearing in the second limiting groove, so as to adjust the extension direction of the second flexible cable, facilitating the connection of the second flexible cable around the end of the first base 717 with the first sliding block 714 and the second sliding block 713.

[0167] 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 at two sides of the first base 717.

[0168] In an embodiment of the present application, as shown in Figure 5 The traction mechanism includes a traction rod 709, a first rotating shaft fixing seat 707 and a second rotating shaft fixing seat 710. The first rotating shaft fixing seat 707 is connected to the first sliding block 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.

[0169] In the present embodiment, by fixing the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 on the first sliding block 714 and the cabinet 1 respectively, and connecting them through the traction rod 709, the distance between the first sliding block 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 sliding block 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 sliding block 714 slides on the first base 717, and the second sliding block 713 is driven to slide to realize the movement of the door plate 21 relative to the cabinet door 2.

[0170] 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.

[0171] In another aspect of the embodiment of the present application, as shown in Figure 3 and Figure 4As 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 pivotally 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.

[0172] 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, and the second sliding block 713 is driven by the flexible cable 706 to slide away from the first hinge 4, 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.

[0173] 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, so as 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 the wall, object or other obstacles on the side during the closing or opening of the cabinet door 2.

[0174] 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.

[0175] In one embodiment of the present application, as shown in Figure 5 to Figure 6 The first connecting block 712 is provided on the second sliding block 713, and the slot is formed on the first connecting block 712 for hanging the door panel 21.

[0176] In the present embodiment, the first connecting block 712 is provided on the second sliding block 713, and the slot is formed on the first connecting block 712. Correspondingly, the connecting assembly (such as a hook, a plug, etc.) adapted to the slot is provided on the door panel 21, so as to mount the door panel 21 on the first connecting block 712, and 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.

[0177] 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 Figure 8 to Figure 10 . The sliding mechanism includes a guide member 730, a sliding member 740, a linkage assembly 750, and a driving rod 760.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] 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.

[0185] Optionally, the linkage assembly 750 can be a parallel four-bar linkage mechanism, or a crank rocker mechanism.

[0186] 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.

[0187] In some embodiments, as shown in Figure 8 The link assembly 750 includes a first link 751 and a second link 752.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] 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 driven to move towards the side away from the hinge, and the sliding piece 740 is 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.

[0192] 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 driven to move towards the side close to the hinge, and the sliding piece 740 is 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 is prevented from interfering with the cabinet around the refrigeration equipment.

[0193] The embodiment drives the sliding piece 740 to move along the width direction by changing the included angle between the first connecting rod 751 and the second connecting rod 752 through the first hinge shaft 753 limited to move along the thickness direction, and realizes the movement of the door plate relative to the cabinet door, so that the structure is simple and the volume is small.

[0194] In some embodiments, as shown in FIG. 7, the driving rod 760 includes a connecting piece. Figure 8

[0195] 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.

[0196] 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, 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.

[0197] 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, 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.

[0198] ​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.

[0199] 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.

[0200] 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.

[0201] 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.

[0202] In some embodiments, as shown in Figure 9 The guide structure 731 includes a first limiting slot 7311.

[0203] The first limiting slot 7311 extends along the thickness direction.

[0204] 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.

[0205] 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.

[0206] 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.

[0207] In some embodiments, as shown in Figure 9 The guide structure 731 further includes a second limiting groove 7312.

[0208] The second limiting groove 7312 extends along the width direction and is in communication with the first limiting groove 7311.

[0209] 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.

[0210] The second hinged shaft 754 and the third hinged shaft 755 are respectively arranged on the two sides of the first limiting groove 7311.

[0211] 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 ensuring the reliability of the door panel moving along the width direction of the cabinet door.

[0212] In some embodiments, as shown in Figure 8 The sliding mechanism further includes an elastic piece 770.

[0213] The elastic piece 770 is arranged between the guide piece 730 and the sliding piece 740.

[0214] 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.

[0215] 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.

[0216] 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.

[0217] 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.

[0218] 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.

[0219] Specifically, the elastic piece 770 can be an elastic sheet, an elastic block, or a spring.

[0220] 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.

[0221] In some embodiments, as shown in Figure 8 to Figure 10 The guide piece 730 includes a fixed plate 732 and a sliding groove 733.

[0222] The fixed plate 732 is configured to be arranged on the cabinet door.

[0223] 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.

[0224] 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 move stably and reliably in the width direction of the cabinet door.

[0225] In some embodiments, as shown in Figure 9 and Figure 10 The guide piece 730 further includes a sliding sleeve 734, and the sliding sleeve 734 is arranged at one end of the sliding groove 733 away from the hinge position.

[0226] 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, 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.

[0227] The elastic piece 770 is arranged between the sliding sleeve 734 and the sliding contact 745.

[0228] 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.

[0229] 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.

[0230] In some embodiments, as shown in Figure 8 The elastic piece 770 includes a spring, which is sleeved on the outer side of the guide rod 741 and is limited between the sliding sleeve 734 and the sliding contact 745.

[0231] It can be understood that when the elastic piece 770 is 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.

[0232] In some embodiments, as shown in Figure 8 and Figure 9 The sliding piece 740 further includes a first connecting arm 743 and a second connecting arm 744.

[0233] 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.

[0234] The sliding sleeve 734 and the sliding contact 745 are located between the first connecting arm 743 and the second connecting arm 744.

[0235] 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.

[0236] 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 mounted on the sliding block 742, the fixed plate 732 is mounted 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 mounted on the cabinet door, and facilitating the movement of the door panel along the cabinet door.

[0237] 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.

[0238] In an embodiment of the present application, Figure 4 、 Figure 11 and Figure 12 As shown in the figure, the door body assembly further comprises a first driven guide rail mechanism 8.

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

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

[0240] Further, the first driven guide rail mechanism 8 further comprises a third fixed seat 801 and a fourth fixed seat 802, which are also provided with limiting grooves similar to the first fixed seat 701 and the second fixed seat 702.

[0242] It can be understood that the fourth fixed seat 802 can also be provided with a third fixed hole; the second base 817 is provided with a third waist-shaped hole extending along the width direction of the second base 817; the third adjusting part 804 passes through the third fixed hole and is slidably arranged in the third waist-shaped hole, so as to adjust the position of the third adjusting part 804 in the third waist-shaped hole.

[0243] Further, the third fixed seat 801 is provided with a fourth waist-shaped hole extending along the width direction of the second base 817. The second base 817 is provided with a fourth fixed hole. The fourth adjusting part 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 third fixed seat 801 relative to the external structure through the position of the fourth adjusting part 803 in the fourth waist-shaped hole.

[0244] It can be understood that the fourth fixed seat 802 can also be provided with a fourth waist-shaped hole extending along the width direction of the third base 902; the fourth adjusting part 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 adjusting part 803 in the fourth waist-shaped hole.

[0245] In an embodiment of the present application, as shown in Figure 4 , Figure 13 and Figure 14 , the door body assembly further comprises a second driven guide rail mechanism 9, which is arranged in a different axis with the sliding mechanism. The second driven guide rail mechanism 9 comprises a third base 902 and a fourth sliding block 903.
