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

[0031] Combine the following Figures 1 to 5 The 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.

[0032] In one embodiment of the present application, Figures 1 to 5As shown, the sliding door mechanism 7 is applied to a refrigeration device and is arranged on the door 2. The door 2 is rotatably connected to the housing 1. A door panel 21 that can slide along the door 2 is arranged on the outer side of the door 2. The sliding door mechanism 7 includes: a base, a first slider 715, a second slider 709, and a connecting member. The base is arranged on the door 2, and a first guide rail 710 and a second guide rail 705 are formed on both sides along the height direction of the door 2. The first slider 715 is slidably arranged on the first guide rail 710, and the first slider 715 is connected to the housing 1 through a traction mechanism. The second slider 709 is slidably arranged on the second guide rail 705, and is used to be connected to the door panel 21. The two ends of the connecting member are respectively connected to the first slider 715 and the second slider 709. During the process of opening or closing the box door 2, the first slider 715 moves along the first guide rail 710 under the drive of the traction mechanism, and 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 to drive the door panel 21 to move relative to the width direction of the box door 2.

[0033] It is understandable that the width direction of the door 2 is parallel to the plane where the door 2 is located and perpendicular to the rotation axis of the door 2, so that the door panel 21 can be away from or close to the rotation axis of the door 2 (such as Figure 4 It should be noted that the parallel and perpendicular relationship of the present application needs to take into account the installation error between the various components, and the error of plus or minus 10° should be understood as the scope of protection of the patent.

[0034] The base of this embodiment is arranged on the box door 2, the first slider 715 is connected to the box body 1 through a traction mechanism, the second slider 709 is slidably connected to the door panel 21 arranged on the outside of the box door 2, and the connecting member can be a connecting member such as a traction rope and a transmission belt. The two ends of the connecting member are respectively connected to the first slider 715 and the second slider 709. When the box door 2 is opened or closed, the distance between the box body 1 and the box door 2 changes, so that the box body 1 drives the first slider 715 to slide along the first guide rail 710 through the traction mechanism. The first slider 715 can drive the second slider 709 to move synchronously through the pulling of the connecting member, and make the two sliders slide relative to each other in opposite directions to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid obstacles on both sides during the process of turning the box door 2.

[0035] 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.

[0036] At the same time, by respectively arranging the first guide rail 710 and the second guide rail 705 on both sides along the height direction of the box door 2, the first slider 715 and the second slider 709 are also arranged along the height direction of the box door 2, which is beneficial to reduce the size of the entire door body assembly along the width or thickness direction of the box door 2.

[0037] 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 a 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 and opening.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] In one embodiment of the present application, Figure 3 As shown, the sliding door mechanism 7 further includes a first rolling ball 7141 and a second rolling ball 7071. A first rolling gap is formed between the first slider 715 and the first guide rail 710, and the first rolling ball 7141 is rollably 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 rolling ball 7071 is rollably disposed in the second rolling gap.

[0042] In this embodiment, by forming a first rolling gap and a second rolling gap respectively between the first slider 715 and the first guide rail 710, and between the second slider 709 and the second guide rail 705, 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, and a rollable first ball 7141 and a second ball 7071 are respectively arranged 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 rolling the first ball 7141, and the second slider 709 can slide along the second guide rail 705 by rolling the second ball 7071, so that the friction is small and the sliding is smoother.

[0043] In one embodiment of the present application, Figure 3 As shown, the first rolling balls 7141 and the second rolling balls 7071 are provided in multiple groups, the first guide rail 710 is provided with multiple first concave surfaces arranged in sequence along its circumference, the first slider 715 is formed with a first groove, the side wall of the first groove and the multiple first concave surfaces form multiple rows of first rolling gaps, and each group of first rolling balls 7141 is respectively arranged in the multiple rows of first rolling gaps. The second guide rail 705 is provided with multiple second concave surfaces arranged in sequence along its circumference, the second slider 709 is formed with a second groove, the side wall of the second groove and the multiple second concave surfaces form multiple rows of second rolling gaps, and each group of second rolling balls 7071 is respectively arranged in the multiple rows of second rolling gaps.

[0044] In this embodiment, by providing a first groove on the first slider 715 and providing a first concave surface on the first guide rail 710, the first concave surface and the first groove relatively form a first rolling gap, the first concave surface and the first groove respectively abut on both sides of the first ball 7141, and the first ball 7141 can roll in the first rolling gap to achieve relative sliding between the first slider 715 and the first guide rail 710. At the same time, the first concave surface can limit the first ball 7141 in the circumferential direction of the first guide rail 710 to prevent the first ball 7141 from circumferentially deviating on the first guide rail 710, so that the sliding of the first slider 715 is more stable and smooth. Similarly, the second groove on the second slider 709 and the second concave surface of the second guide rail 705 relatively form a second rolling gap, the second concave surface and the second groove respectively abut on both sides of the second ball 7071, so that the second ball 7071 does not deviate circumferentially when rolling to achieve relative sliding between the second slider 709 and the second guide rail 705, so that the sliding of the second slider 709 is more stable and smooth.

[0045] Optionally, the first concave surface is an arcuate surface that fits the first ball 7141, and a position on the side wall of the first groove corresponding to the first concave surface also forms an arcuate surface that fits the first ball 7141, so that the first concave surface and the first groove can better fit the first ball 7141, with a larger force-bearing area, and can be more stable and reliable during rolling; similarly, the second concave surface is an arcuate surface that fits the second ball 7071, and a position on the side wall of the second groove corresponding to the second concave surface also forms an arcuate surface that fits the second ball 7071, so that the second concave surface and the second groove can better fit the second ball 7071, with a larger force-bearing area, and can be more stable and reliable during rolling.

[0046] In one embodiment of the present application, Figure 3 As 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, and the first support frame 714 is provided with a first limiting notch at a position corresponding to the first rolling gap, 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, and the second support frame 707 is provided with a second limiting notch at a position corresponding to the second rolling gap, and the second ball 7071 is disposed in the second limiting notch.

[0047] In this embodiment, a first support frame 714 is set between the first slider 715 and the first guide rail 710, and a first limiting notch is formed on the first support frame 714 to set the first ball 7141, so as to limit the first ball 7141 and prevent the first ball 7141 from rolling and deviating in the first rolling gap, so that the sliding of the first slider 715 is more stable and reliable; similarly, a second support frame 707 is set between the second slider 709 and the second guide rail 705 to limit the second ball 7071, so that the sliding of the second slider 709 is more stable and reliable.

[0048] In one embodiment of the present application, Figure 1 and Figure 2 As 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 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 base, and its two ends are respectively connected to the other ends of the first slider 715 and the second slider 709.

[0049] In this embodiment, the first connecting member 706 is connected to the first slider 715 and the second slider 709 by bypassing one end of the base, and when the first slider 715 slides toward the end away from the base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide toward the end close to the base through the first connecting member 706; at the same time, the second connecting member 712 is connected to the first slider 715 and the second slider 709 by bypassing the other end of the base, and when the first slider 715 slides toward the other end away from the base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide toward the other end close to the base through the second connecting member 712, thereby achieving that when the first slider 715 slides toward both ends of the base respectively, the second slider 709 and the first slider 715 can be driven to slide in the opposite direction, so that the door panel 21 can slide relative to the box door 2 as the box door 2 rotates when the box door 2 is opened and closed, so as to avoid interference with obstacles and affecting the opening and closing of the box door 2.

[0050] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the sliding door mechanism 7 also includes: a first fixed seat 704 and a second fixed seat 711, the first fixed seat 704 is connected to one end of the base, and a first limiting groove is formed, and both ends of the first limiting groove are connected to one end of the first guide rail 710 and the second guide rail 705, and a part of the first connecting member 706 is slidably arranged in the first limiting groove; the second fixed seat 711 is connected to the other end of the base, and a second limiting groove is formed, and both ends of the second limiting groove are connected to the other end of the first guide rail 710 and the second guide rail 705, and a part of the second connecting member 712 is slidably arranged in the second limiting groove.

[0053] In this embodiment, a portion of the first connecting member 706 is abutted against the support bearing 716 to adjust the movement and extension direction of the first connecting member 706, thereby facilitating the first connecting member 706 to bypass the end of the base and connect with the first slider 715 and the second slider 709.

[0054] It is understandable that a rotatable support bearing 716 may also be provided in the second limiting groove; a portion of the second connecting member 712 abuts against the support bearing 716 in the second limiting groove to adjust the extension direction of the second connecting member 712, making it convenient to connect the second connecting member 712 around the end of the base and to the first slider 715 and the second slider 709.

[0055] Specifically, in one embodiment of the present application, a fixing hole is provided on the first fixing seat 704. The sliding door mechanism 7 also includes a fixing member, which passes through the fixing hole to be connected to the external structure.

[0056] In this embodiment, a fixing hole is provided on the first fixing seat 704, and a fixing member is passed through the fixing hole to be fixed in the external structure, so that the first fixing seat 704 is fixed in the external structure, thereby fixing the base on the external structure (such as the box door 2).

[0057] It is understandable that a fixing hole is provided on the second fixing seat 711. The sliding door mechanism 7 also includes a fixing member, which passes through the fixing hole to be connected to the external structure.

[0058] In this embodiment, a fixing hole is provided on the second fixing seat 711, and a fixing member is passed through the fixing hole and fixed in the external structure so as to fix the second fixing seat 711 in the external structure, thereby fixing the base on the external structure (such as the box door 2).

[0059] In another embodiment of the present application, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a door assembly is provided, comprising: 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 suitable for opening or closing the storage space of the box body 1. The door panel 21 is slidably arranged on the outside of the box door 2; the sliding door mechanism 7 is arranged on the box door 2, 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. In the process of opening or closing 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 relative to the width direction of the box door 2.

[0060] In this embodiment, during the process of the door 2 rotating to the outside of the box body 1 to open (such as Figure 4 In the embodiment shown in the figure (shown by the curved arrow in the middle), the first slider 715 slides in the direction close to the first hinge 4 under the drive of the box body 1 and the traction mechanism, and the first slider 715 drives the second slider 709 to slide in the direction away from the first hinge 4 through the connecting member, thereby driving the door panel 21 to slide in the direction away from the first hinge 4, thereby avoiding the interference between the door panel 21 and the obstacles on the outside. Similarly, in the process of the box door 2 rotating to one side of the box body 1 to close, the sliding door mechanism 7 drives the door panel 21 to slide in the direction close to the first hinge 4, thereby avoiding the interference between the door panel 21 and the obstacles after closing. At the same time, by respectively arranging the first guide rail 710 and the second guide rail 705 on both sides of the base along the height direction of the box door 2, the first slider 715 and the second slider 709 are distributed along the thickness direction of the box door 2, which is conducive to reducing the size of the door body assembly in the thickness direction or width direction of the box door 2.

[0061] According to the door body assembly of the embodiment of the present application, a sliding door mechanism 7 is provided on the box door 2, and the sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21, so that when the box door 2 is rotated to open or close relative to the box body 1, the door panel 21 is driven to slide in the width direction of the box door 2, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening of the box door 2.

[0062] It can be understood that the sliding door mechanism 7 has the beneficial effects of the above-mentioned embodiment, and the door body assembly correspondingly has the beneficial effects of the above-mentioned embodiment. Its specific implementation method can refer to the above-mentioned embodiment, and this application will not repeat it again.

[0063] In one embodiment of the present application, Figure 1 , Figure 2 , Figure 4 and Figure 5As 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 sliding block 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.

[0064] In this embodiment, the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 are respectively fixed on the first slider 715 and the box body 1, and the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 are connected by a traction rod 702, so that the distance between the first slider 715 and the second rotating shaft fixing seat 701 remains unchanged. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes, so that the first slider 715 is pulled through the transmission connection of the traction rod 702, the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, so that the first slider 715 slides on the base, and drives the second slider 709 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0065] Specifically, one end of the traction rod 702 is rotatably connected to the first rotation shaft fixing seat 713 via a pin shaft 703 , and the other end of the traction rod 702 is rotatably connected to the second rotation shaft fixing seat 701 via another pin shaft 703 .

[0066] In one embodiment of the present application, Figure 1 and Figure 2 As shown, a connecting block 708 is provided on the second sliding block 709 , and a slot for hanging the door panel 21 is formed on the connecting block 708 .

[0067] In this embodiment, a connecting block 708 is provided on the second slider 709, and a slot is provided on the connecting block 708 for hanging with the door panel 21, so that the user can install the door panel 21 on the connecting block 708 conveniently, so that when the second slider 709 slides, it can drive the door panel 21 to slide relative to the box door 2.

[0068] It is understandable that the door panel 21 is also provided with a plug-in component or a hook that matches the slot.

[0069] In another embodiment of the present application, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a refrigeration device is provided, comprising: a box body 1 and a door assembly as provided in any of the above embodiments. The box body 1 forms a storage space, and the door 2 is rotatably connected to the box body 1, suitable for opening or closing the storage space.

[0070] In this embodiment, the door assembly includes: a door 2, a door panel 21 and a sliding door mechanism 7. The sliding door mechanism 7 is disposed on the door 2 and is configured to drive the door panel 21 to move relative to the width direction of the door 2 during the process of opening or closing the door 2.

[0071] By setting a door panel 21 on the cabinet door 2, when the refrigeration equipment is embedded and set in a groove-shaped space, or set between two cabinets, the door panel 21 can be set flush with the cabinets on the side walls or both sides of the groove to reduce the gap between the refrigeration equipment and the adjacent walls or cabinets, making it more beautiful.

[0072] At the same time, when the box door 2 rotates, the sliding door mechanism 7 can drive the door panel 21 to move relative to the box door 2 during the rotation of the box door 2 to stay as far away as possible from obstacles such as the wall or cabinet of the side door of the box body 1, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the box door 2, causing the box door 2 to be unable to open or close normally.

[0073] The combination of the door 2 and the door panel 21 can prevent the door panel 21 from interfering with surrounding objects when the refrigeration device is opened and closed, greatly improving the convenience of use. This design advantage is particularly obvious in a narrow kitchen environment. In addition, the arrangement of the slider and the guide rail in the sliding door mechanism 7 enables the door panel 21 to move smoothly during the opening and closing process, thereby improving the service life and stability of the refrigerator, and at the same time helping to reduce the size of the door assembly and the refrigerator in the thickness or width direction.

[0074] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiments. The specific implementation methods thereof may refer to the above embodiments, and will not be described in detail in this application.

[0075] It is understandable that there may be multiple storage spaces.

[0076] It is understandable that the multiple storage spaces can be arranged arbitrarily, such as up and down, left and right, etc. The multiple storage spaces can be set with storage conditions according to storage needs, for example, part of the storage space is set as a refrigerator, and another part of the storage space is set as a freezer.

[0077] like Figure 5 As shown, an application scenario based on the above embodiment is as follows: the refrigeration equipment can be installed in a groove structure in the middle of a cabinet. A door panel 21 is provided on the outside of the door 2 of the cabinet 1 of the refrigeration equipment, and the material and color of the door panel 21 can be designed to be similar or the same as the material color of the outer wall of the cabinet. When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet at the opening edge of the groove structure, and fits the opening of the groove structure as closely as possible, so that the door panel 21 and the outer wall of the cabinet can maintain visual consistency and the gap is small, which is more beautiful.

[0078] When the door 2 is rotated outward to open, the sliding door mechanism 7 drives the door panel 21 to slide in the direction away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side close to the first hinge 4, which causes the door 2 to be unable to open to a larger angle. When the door 2 is rotated to close, the sliding door mechanism 7 drives the door panel 21 to slide in the direction close to the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side away from the first hinge 4, which causes the door 2 to be unable to be completely closed and affects the refrigeration preservation effect in the storage space. When the door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet body.

[0079] In one embodiment of the present application, Figure 4 As shown, the box body 1 has a first storage space and a second storage space. There are two door body assemblies, including 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.

[0080] In this embodiment, the first storage space and the second storage space are provided on the box body 1, so that the items to be stored can be stored separately according to the needs. The first storage space and the second storage space are respectively provided with a first door assembly and a second door assembly, so that when the box door 2 of the first door assembly and the second door assembly is turned to open or close, the corresponding door panel 21 can slide relative to the box door 2 to avoid obstacles.

[0081] 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 is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions 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 be included in the scope of the claims of the present invention.
