[0058] The following is combined with Figures 1 to 5The sliding door mechanism, door assembly and refrigeration device of the present application are described. The sliding door mechanism and door assembly of the present application can be applied to the door or cabinet door of household appliances, such as the door of a refrigerator, but it should be understood that the door panel mechanism and door assembly of the present application can also be applied to a dishwasher, a washing machine or any other suitable device. The refrigeration device of the present application is applied to a refrigerator, for example, but it should be understood that the refrigeration device of the present application can also be applied to a freezer or any other suitable device.

[0059] In one embodiment of the present application, Figure 1 , Figure 2 and Figure 5 As shown, the sliding door mechanism 7 is applied to a refrigeration device, which includes a box body 1, a box door 2 and a door panel 21. The box door 2 is rotatably connected to the box body 1, and a door panel 21 is provided on the outer side of the box door 2 along which a sliding door panel 21 is provided. The sliding door mechanism 7 includes: a base, which is used to be set on the box door 2, and a first guide rail 710 is formed on the inner side, and a second guide rail 705 is formed on the outer side; a first slider 715 and a traction mechanism, the first slider 715 is slidably connected to the first guide rail 710; the first slider 715 is connected to the box body 1 through the traction mechanism; the second slider 709 is slidably mounted outside the second guide rail 705 and is used to be connected to the door panel 21; a connecting member, the two ends of which are respectively connected to the first slider 715 and the second slider 709; in the process of opening or closing the box door 2, when the first slider 715 moves along the first guide rail 710 driven by the traction mechanism, the first slider 715 drives the second slider 709 to move in the opposite direction on the second guide rail 705 through the connecting member.

[0060] The first base of this embodiment can be arranged on the box door 2, the first slider 715 is connected to the box body 1 through a traction mechanism, and the second slider 709 is connected to the door panel 21 arranged outside the box door 2 in a slidable manner. The connecting member can be a connecting member such as a traction rope and a transmission belt, and the two ends of the connecting member are connected to the first slider 715 and the second slider 709 respectively, so that the first slider 715 can drive the second slider 709 to move synchronously, thereby driving the door panel 21 to slide relative to the box door 2.

[0061] By properly setting the extending direction of the connecting member, the first slider 715 and the second slider 709 move in opposite directions, so as to drive the door panel 21 to avoid obstacles.

[0062] Specifically, when the door 2 is rotated to the outside of the box body 1 to open, the box body 1 drives the first slider 715 to slide in the direction close to the first hinge 4 through the traction mechanism, and at the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., away from the first hinge 4) through the connecting member, thereby avoiding interference between the door panel 21 and obstacles on the outside. When the door 2 is rotated to one side of the box body 1 to close, the box body 1 drives the first slider 715 to slide in the direction away from the first hinge 4 through the traction mechanism, and at the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., close to the first hinge 4) through the connecting member, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0063] According to the sliding door mechanism 7 of the present application, a first guide rail 710 and a second guide rail 705 are arranged on both sides of the first base, and a first slider 715 and a second slider 709 are slidably arranged on the first guide rail 710 and the second guide rail 705, respectively. The first slider 715 and the second slider 709 can slide synchronously along the guide rails driven by the connecting member, and the sliding directions are opposite. The first slider 715 is transmission-connected to the box body 1 through a traction mechanism, and the second slider 709 is connected to the door panel 21 arranged on the outside of the box door 2, so that when the box door 2 rotates, the box body 1 drives the two sliders to slide relative to each other through the traction mechanism and the connecting member, so as to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid obstacles on both sides during the process of the box door 2 turning to open and close.

[0064] It should be noted that, in practical applications, the designs of the first slider 715, the second slider 709 and other sliders in the present application 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.

[0065] From the material point of view, the first slider 715, the second slider 709 and other sliders in the present application can be made of materials with high wear resistance, low friction coefficient and good stability, such as metal alloys, engineering plastics or special lubricating materials. The selection of these materials is intended to improve the durability of the slider, reduce wear and noise during sliding, and ensure smooth sliding.

[0066] In terms of structural design, the first slider 715, the second slider 709 and other sliders in the present application can adopt various forms of guide rail contact surfaces, such as plane contact, ball contact or sliding bearing contact. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness and maintenance convenience should be comprehensively considered when selecting.

[0067] In one embodiment of the present application, as Figure 3 shown, the sliding door mechanism 7 further includes a first ball 7141 and a second ball 7071. A first rolling gap is formed between the first slider 715 and the first guide rail 710, and the first ball 7141 is rotatably disposed in the first rolling gap; a second rolling gap is formed between the second slider 709 and the second guide rail 705, and the second ball 7071 is rotatably disposed in the second rolling gap.

[0068] In this embodiment, by forming a first rolling gap between the first slider 715 and the first guide rail 710 and a second rolling gap between the second slider 709 and the second guide rail 705 respectively, direct contact between the first slider 715 and the first guide rail 710, and between the second slider 709 and the second guide rail 705 can be avoided. The rotatable first ball 7141 and the second ball 7071 are respectively disposed in the first rolling gap and the second rolling gap, so that the first slider 715 can slide along the first guide rail 710 by the rolling of the first ball 7141, and the second slider 709 can slide along the second guide rail 705 by the rolling of the second ball 7071, with small friction and smoother sliding.

[0069] In one embodiment of the present application, as Figure 3 shown, there are multiple groups of the first ball 7141 and the second ball 7071. A plurality of first concave surfaces are formed on the first guide rail 710, and a first groove is formed on the first slider 715. The side walls of the first groove and the plurality of first concave surfaces form multiple rows of first rolling gaps, and each group of the first balls 7141 is respectively disposed in each row of the first rolling gaps. The second guide rail 705 forms a plurality of second concave surfaces, and a second groove is formed on the second slider 709. The side walls of the second groove and the plurality of second concave surfaces form multiple rows of second rolling gaps, and each group of the second balls 7071 is respectively disposed in each row of the second rolling gaps.

[0070] In this embodiment, by providing multiple rows of first rolling gaps and arranging a set of first balls 7141 in each row of the first rolling gaps, multiple sets of first balls 7141 can form multiple rolling support points between the first slider 715 and the first guide rail 710, making the sliding of the first slider 715 relative to the first guide rail 710 more stable and smooth. Similarly, by providing multiple rows of second rolling gaps and arranging a set of second balls 7071 in each row of the second rolling gaps, multiple sets of second balls 7071 can also form multiple rolling support points between the second slider 709 and the second guide rail 705, making the sliding of the second slider 709 relative to the first guide rail 710 more stable and smooth. At the same time, by providing a first groove on the first slider 715 and a first concave surface on the first guide rail 710, the first concave surface and the first groove relatively form a first rolling gap, and the first concave surface and the first groove respectively abut against both sides of the first ball 7141. The first ball 7141 can roll within the first rolling gap to achieve the relative sliding of the first slider 715 and the first guide rail 710. Meanwhile, the first concave surface can limit the position of the first ball 7141 on the first guide rail 710 to prevent the first ball 7141 from shifting on the first guide rail 710, making the sliding of the first slider 715 more stable and smooth. Similarly, the second groove on the second slider 709 and the second concave surface on the second guide rail 705 relatively form a second rolling gap, and the second concave surface and the second groove respectively abut against both sides of the second ball 7071, so that the second ball 7071 can roll without shifting when achieving the relative sliding of the second slider 709 and the second guide rail 705, making the sliding of the second slider 709 more stable and smooth.

[0071] Optionally, multiple first rolling gaps in each row can be arranged at intervals along the extending direction of the first guide rail 710, and multiple second rolling gaps in each row can be arranged at intervals along the extending direction of the second guide rail 705.

[0072] Optionally, the first concave surface is an arc surface that fits the first ball 7141, and an arc surface that fits the first ball 7141 is also formed at the position corresponding to the first concave surface on the side wall of the first groove, so that the first concave surface and the first groove can better fit the first ball 7141, with a larger force-bearing area and more stable and reliable rolling; similarly, the second concave surface is an arc surface that fits the second ball 7071, and an arc surface that fits the second ball 7071 is also formed at the position corresponding to the second concave surface on the side wall of the second groove, so that the second concave surface and the second groove can better fit the second ball 7071, with a larger force-bearing area and more stable and reliable rolling.

[0073] In an embodiment of the present application, as Figure 3As shown, the sliding door mechanism 7 further includes: a first support frame 714 and a second support frame 707. The first support frame 714 is disposed between the first slider 715 and the first guide rail 710. At a position corresponding to the first rolling gap, the first support frame 714 is provided with a first limiting notch, and the first ball 7141 is disposed in the first limiting notch. The second support frame 707 is disposed between the second slider 709 and the second guide rail 705. At a position corresponding to the second rolling gap, the second support frame 707 is provided with a second limiting notch, and the second ball 7071 is disposed in the second limiting notch.

[0074] In this embodiment, by providing the first support frame 714 between the first slider 715 and the first guide rail 710, a first limiting notch is formed on the first support frame 714 to dispose the first ball 7141, so as to limit the first ball 7141 and prevent the first ball 7141 from rolling and shifting in the first rolling gap, making the sliding of the first slider 715 more stable and reliable; similarly, by providing the second support frame 707 between the second slider 709 and the second guide rail 705 to limit the second ball 7071, the sliding of the second slider 709 is made more stable and reliable.

[0075] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the connecting member includes: a first connecting member 706 and a second connecting member 712. The first connecting member 706 bypasses one end of the first base, and its two ends are respectively connected to one end of the first slider 715 and the second slider 709; the second connecting member 712 bypasses the other end of the first base, and its two ends are respectively connected to the other end of the first slider 715 and the second slider 709.

[0076] In this embodiment, by connecting the first connecting member 706 around one end of the first base to the first slider 715 and the second slider 709 respectively, when the first slider 715 slides away from this end of the first base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide towards this end of the first base through the first connecting member 706; at the same time, by connecting the second connecting member 712 around the other end of the first base to the first slider 715 and the second slider 709 respectively, when the first slider 715 slides away from the other end of the first base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide towards the other end of the first base through the second connecting member 712, so as to realize that when the first slider 715 slides towards both ends of the first base respectively, it can drive the second slider 709 to slide in the opposite direction to the first slider 715, and further enable the door panel 21 to slide relative to the box door 2 as the box door 2 rotates when the box door 2 is opened and closed, so as to avoid interference with obstacles and affect the opening and closing of the box door 2.

[0077] In an embodiment of the present application, asFigure 1 and Figure 2 As shown in Figure 2 , the sliding door mechanism 7 further includes: a first fixing seat 704 and a second fixing seat 711. The first fixing seat 704 is connected to one end of the first base and is formed with a first limiting groove. Two ends of the first limiting groove are butted against one ends of the first guide rail 710 and the second guide rail 705. A part of the first connecting member 706 is slidably disposed in the first limiting groove; the second fixing seat 711 is connected to the other end of the first base and is formed with a second limiting groove. Two ends of the second limiting groove are butted against the other ends of the first guide rail 710 and the second guide rail 705.

[0078] In this embodiment, by respectively disposing the first fixing seat 704 and the second fixing seat 711 at two ends of the first base, the first fixing seat 704 and the second fixing seat 711 are respectively formed with a first limiting groove and a second limiting groove that are butted against the first guide rail 710 and the second guide rail 705, respectively limiting and guiding the positions of the first connecting member 706 and the second connecting member 712, so that the sliding of the first connecting member 706 and the second connecting member 712 is smoother and more stable.

[0079] Specifically, in an embodiment of the present application, the first fixing seat 704 is provided with a fixing hole. The sliding door mechanism 7 further includes a fixing member, and the fixing member passes through the fixing hole to be connected to an external structure.

[0083] In an embodiment of another aspect of the present application, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, a door assembly is provided, including: a box door 2, a door panel 21, and a sliding door mechanism 7 provided in any of the above embodiments. The box door 2 is rotatably connected to the box body 1 and is adapted to open or close the storage space of the box body 1. The door panel 21 is slidably disposed outside the box door 2; the sliding door mechanism 7 is disposed on the box door 2, the first slider 715 is drivingly connected to the box body 1 through a traction mechanism, and the second slider 709 is connected to the door panel 21. During the opening or closing process of the box door 2, the first slider 715 and the second slider 709 move in opposite directions to drive the door panel 21 to move in the width direction of the box door 2 relative to the box door 2.

[0084] It can be understood that the width direction of the box door 2 is parallel to the plane where the box door 2 is located and perpendicular to the rotation axis of the box door 2, so that the door panel 21 can move away from or close to the rotation axis of the box door 2 (as Figure 4 shown by the double-headed arrow in the figure). It should be noted that for the parallel and perpendicular relationships in this application, the installation errors between various components need to be considered, and an error of plus or minus 10° should be understood as the scope protected by the patent.

[0085] Specifically, during the process of the box door 2 rotating and opening towards the outside of the box body 1 (as Figure 4 shown by the arc arrow in the figure), the first slider 715 slides towards the direction close to the first hinge 4 under the drive of the box body 1 and the traction mechanism. The first slider 715 drives the second slider 709 to slide away from the first hinge 4 through a connecting member, thereby driving the door panel 21 to slide away from the first hinge 4, and further avoiding interference between the door panel 21 and the obstacles outside. Similarly, during the process of the box door 2 rotating and closing towards one side of the box body 1, the sliding door mechanism 7 drives the door panel 21 to slide towards the direction close to the first hinge 4, thereby avoiding interference between the door panel 21 and the obstacles after closing.

[0086] According to the door assembly of the embodiment of the present application, a sliding door mechanism 7 is provided on the box door 2. The sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21 to drive the door panel 21 to slide in the width direction of the box door 2 relative to the box door 2 during the process of the box door 2 rotating and opening or closing relative to the box body 1, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening process of the box door 2.

[0087] It can be understood that if the sliding door mechanism 7 has the beneficial effects of the above embodiments, the door assembly correspondingly has the beneficial effects of the above embodiments. The specific implementation manners can refer to the above embodiments, and will not be elaborated in this application.

[0088] In an embodiment of the present application, as Figure 1 and Figure 2As shown, the traction mechanism includes a traction rod 702, a first rotating shaft fixing seat 713, and a second rotating shaft fixing seat 701. The first rotating shaft fixing seat 713 is connected to the first slider 715, and the second rotating shaft fixing seat 701 is used to be connected to the box body 1. One end of the traction rod 702 is rotatably connected to the first rotating shaft fixing seat 713, and the other end of the traction rod 702 is rotatably connected to the second rotating shaft fixing seat 701.

[0089] In this embodiment, by fixing the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 on the first slider 715 and the box body 1 respectively, and connecting them through the traction rod 702 between the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, the distance between the first slider 715 and the second rotating shaft fixing seat 701 is always kept unchanged. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes. Thus, through the transmission connection of the traction rod 702, the first rotating shaft fixing seat 713, and the second rotating shaft fixing seat 701, the first slider 715 is pulled, so that the first slider 715 slides on the first base, and drives the second slider 709 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0090] In an embodiment of the present application, as Figure 1 shown, a connecting block 708 is provided on the second slider 709, and a slot for hanging the door panel 21 is formed on the connecting block 708.

[0091] In this embodiment, by providing the connecting block 708 on the second slider 709 and providing a slot on the connecting block 708 for hanging the door panel 21, it is convenient for the user to install the door panel 21 on the connecting block 708, so that when the second slider 709 slides, it can drive the door panel 21 to slide relative to the box door 2.

[0092] In an embodiment of another aspect of the present application, as Figure 4 and Figure 5 shown, a refrigeration device is provided, including: a box body 1 and a door body assembly as provided in any of the above embodiments. Wherein, the box body 1 forms a storage space, and the box door 2 is rotatably connected to the box body 1 and is adapted to open or close the storage space.

[0093] In this embodiment, the door body assembly includes: a box door 2, a door panel 21, and a sliding door mechanism 7. The sliding door mechanism 7 is arranged on the box door 2 and is configured to drive the door panel 21 to move relative to the width direction of the box door 2 during the opening or closing process of the box door 2.

[0094] By providing the door panel 21 on the box door 2, when the refrigeration device is an embedded type and is arranged in a groove-shaped space, or is arranged between two cabinets, the door panel 21 can be set flush with the side wall of the groove or the cabinets on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet, making it more beautiful.

[0095] Meanwhile, when the door 2 rotates, the sliding door mechanism 7 can drive the door panel 21 to move relative to the door 2 during the rotation of the door 2 so as to move as far away from obstacles such as the wall of the side door of the cabinet body 1 or the cabinet body, etc., to prevent these obstacles from blocking the door panel 21 and affecting the rotation of the door 2, resulting in the door 2 being unable to be opened or closed normally.

[0096] The combination of the door 2 and the door panel 21 enables the refrigeration device to avoid interference between the door panel 21 and surrounding objects when opening and closing, greatly improving the convenience of use. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the slider and guide rail in the sliding door mechanism 7 enables the door panel 21 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0097] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, then the refrigeration device correspondingly has the beneficial effects of the above embodiments, and its specific implementation manner can refer to the above embodiments, which will not be elaborated in this application.

[0098] It can be understood that there can be multiple storage spaces.

[0099] It can be understood that multiple storage spaces can be arranged arbitrarily, such as arranged vertically or horizontally. Multiple storage spaces can set storage conditions according to storage requirements. For example, some storage spaces are set as refrigerating chambers, and some other storage spaces are set as freezing chambers.

[0100] As Figure 4 shown, based on an application scenario of the above embodiments as follows: The refrigeration device can be installed in a trough-shaped structure in the middle of a cabinet body. A door panel 21 is arranged on the outer side of the door 2 of the cabinet body 1 of the refrigeration device, and the material and color of the door panel 21 can be designed to be similar to or the same as the material color of the outer wall of the cabinet body. When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet body at the opening edge of the trough-shaped structure and fits as closely as possible to the opening of the trough-shaped structure, so that the door panel 21 and the outer wall of the cabinet body can maintain visual consistency and have a small gap, which is more beautiful.

[0101] When the door 2 rotates outward to open, the sliding door mechanism 7 drives the door panel 21 to slide in a direction away from the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side close to the first hinge 4, resulting in the door 2 being unable to be opened to a larger angle. When the door 2 rotates to close, the sliding door mechanism 7 drives the door panel 21 to slide in a direction close to the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side far from the first hinge 4, resulting in the door 2 being unable to be completely closed and affecting the refrigeration preservation effect in the storage space. And when the door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet body again.

[0102] In one embodiment of the present application, the box body 1 has a first storage space and a second storage space. There are two door body assemblies, namely a first door body assembly and a second door body assembly. The box door 2 of the first door body assembly is rotatably connected to the box body 1 to open or close the first storage space, and the box door 2 of the second door body assembly is rotatably connected to the box body 1 to open or close the second storage space.

[0103] In this embodiment, by providing the first storage space and the second storage space on the box body 1, the items to be stored are stored separately according to requirements. The first storage space and the second storage space are respectively provided with a first door body assembly and a second door body assembly, so that when the box doors 2 of the first door body assembly and the second door body assembly are rotated to open and close, the corresponding door panels 21 can slide relative to the box door 2 to avoid obstacles.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
