[0036] One or more of the above technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0037] According to the active sliding door mechanism of the present application, by providing a first guide rail and a second guide rail on both sides of the first base, a first slider and a second slider are slidably provided on the first guide rail and the second guide rail respectively. The first slider and the second slider can slide synchronously along the respective guide rails under the drive of the connecting member, and the sliding directions are opposite. The first slider is connected to the box body through a traction mechanism, and the second slider is connected to the door panel provided on the outer side of the box door. So that when the box door rotates, the box body drives the two sliders to slide relatively through the traction mechanism and the connecting member, so as to drive the door panel to slide relative to the box door, so that the door panel can avoid obstacles on both sides during the opening and closing process of the box door. At the same time, by providing rolling elements between the slider and the guide rail, it is beneficial to reduce the friction force between the slider and the guide rail, making the sliding of the first slider and the second slider smoother, and thus making the sliding of the door panel smoother.

[0038] According to the door body assembly of the embodiment of the present application, an active sliding door mechanism is provided on the box door. The active sliding door mechanism is respectively connected to the box body and the door panel, so as to drive the door panel to slide in the width direction of the box door relative to the box door during the process of the box door rotating and opening or closing relative to the box body, so that the door panel can avoid obstacles such as side walls and objects during the closing or opening process of the box door. At the same time, the rolling elements of the active sliding door mechanism can reduce the friction force received by the slider, making the sliding of the door panel smoother.

[0039] According to the refrigeration device of the embodiment of the present application, by combining the box door and the door panel, the refrigeration device can avoid interference between the door panel and surrounding objects when opening and closing, greatly improving the use convenience. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the slider, the guide rail and the rolling elements between them in the active sliding door mechanism enables the door panel to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0040] Further, by providing multiple groups of first balls between the first slider and the first guide rail, and multiple groups of second balls between the second slider and the second guide rail, the rolling force application points between the slider and the guide rail are more and more dispersed, making the sliding of the first slider and the second slider more stable and smooth.

[0041] Further, by respectively arranging a first support frame between the first slider and the first guide rail and a second support frame between the second slider and the second guide rail, the first ball and the second ball are limited, preventing the first ball and the second ball from shifting, and further making the sliding of the first slider and the second slider more stable and smooth.

[0042] Furthermore, by arranging a driven sliding door mechanism to support and assist the sliding of the door panel, the sliding of the door panel is made more stable and smooth.

[0061] The following will be combined with Figures 1 to 7 Describe the active sliding door mechanism, door body assembly and refrigeration equipment of the present application. The active sliding door mechanism and door body assembly in the present application can be applied to the cabinet doors or door panels of household appliances, such as the cabinet door of a refrigerator. However, it should be understood that the door panel mechanism and door body assembly of the present application can also be applied to dishwashers, washing machines or any other suitable equipment. The refrigeration equipment in the present application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment of the present application can also be applied to freezers or any other suitable equipment.

[0062] In an embodiment of the present application, as Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown in the figure, the active 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 arranged on the box body 1, and a door panel 21 that can slide along it is provided on the outer side of the box door 2. The active sliding door mechanism 7 includes: a first base for being arranged on the box door 2. A first guide rail 710 is formed on one side of the first base, and a second guide rail 705 is formed on the other side. A rolling element, a traction mechanism, a first slider 715 and a second slider 709. The first slider 715 is sleeved on the first guide rail 710. The first slider 715 is connected to the box body 1 through the traction mechanism. The first slider 715 is slidably arranged on the first guide rail 710 through the rolling element. The second slider 709 is sleeved on the second guide rail 705. The second slider 709 is used to connect to the door panel 21. The second slider 709 is slidably arranged on the second guide rail 705 through the rolling element. A connecting member, with both ends respectively connected to the first slider 715 and the second slider 709. In the case where the first slider 715 moves on the first guide rail 710, 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.

[0063] The first base of this embodiment can be arranged on the box door 2. The connecting member can be a connecting component such as a traction rope or a transmission belt. Both ends of the connecting member are respectively connected to the first slider 715 and the second slider 709, enabling the first slider 715 to drive the second slider 709 to move synchronously, and further driving the door panel 21 to slide relative to the box door 2.

[0064] By reasonably setting the extending direction of the connecting member, the first slider 715 and the second slider 709 move in opposite directions during movement, so as to drive the door panel 21 to avoid obstacles.

[0065] Specifically, during the process of the box door 2 rotating and opening towards the outside of the box body 1, the box body 1 drives the first slider 715 to slide towards the direction close to the first hinge 4 through the traction mechanism. 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, thus preventing the door panel 21 from interfering with the external obstacles. During the process of the box door 2 rotating and closing towards one side of the box body 1, the box body 1 drives the first slider 715 to slide away from the first hinge 4 through the traction mechanism. 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, thus preventing the door panel 21 from interfering with the obstacles after closing.

[0066] At the same time, by respectively arranging rolling elements between the first slider 715 and the first guide rail 710, and between the second slider 709 and the second guide rail 705, the sliding friction between the slider and the guide rail is converted into rolling friction, making the sliding of the first slider 715 and the second slider 709 smoother, and thus making the sliding of the door panel 21 smoother.

[0067] According to the active sliding door mechanism 7 of the present application, by providing a first guide rail 710 and a second guide rail 705 on both sides of the first base, a first slider 715 and a second slider 709 are respectively slidably provided on the first guide rail 710 and the second guide rail 705. The first slider 715 and the second slider 709 can synchronously slide along the respective guide rails under the drive of a connecting member, and the sliding directions are opposite. The first slider 715 is connected to the box body 1 through a traction mechanism, and the second slider 709 is connected to a door panel 21 provided on the outer side of the box door 2. So that when the box door 2 rotates, the box body 1 drives the two sliders to slide relatively 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 rotating and opening / closing. At the same time, by providing rolling bodies between the slider and the guide rail, it is beneficial to reduce the friction force between the slider and the guide rail, making the sliding of the first slider 715 and the second slider 709 smoother, and thus making the sliding of the door panel 21 smoother.

[0068] 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 variable 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.

[0069] From the perspective of materials, the first slider 715, the second slider 709, and other sliders in the present application can select 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 aims to improve the durability of the slider, reduce wear and noise during the sliding process, and ensure the smoothness of sliding.

[0070] 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, etc. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is relatively high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, when selecting, factors such as usage conditions, cost-effectiveness, and maintenance convenience should be comprehensively considered.

[0071] In an embodiment of the present application, a card slot 708 is provided on the second slider 709 for plugging with a plug-in member on the door panel 21.

[0072] 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.

[0073] In this embodiment, by respectively 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, 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 tractioned, 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.

[0074] Specifically, one end of the traction rod 702 and the first rotating shaft fixing seat 713 are rotatably connected through a pin shaft 703, and the other end and the second rotating shaft fixing seat 701 are rotatably connected through another pin shaft 703.

[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 both 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 both ends are respectively connected to the other end of the first slider 715 and the second slider 709.

[0076] In this embodiment, by bypassing one end of the first base with the first connecting member 706 and connecting it 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 bypassing the other end of the first base with the second connecting member 712 and connecting it 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 achieve 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 opens and closes, so as to avoid interference with obstacles and affect the opening and closing of the box door 2.

[0077] In one embodiment of the present application, as Figure 1 and Figure 2 shown, the active sliding door mechanism 7 further includes: a first fixed seat 704 and a second fixed seat 711. The first fixed seat 704 is connected to one end of the first base and is formed with a first limiting groove. Both ends of the first limiting groove are butted against 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 first base and is formed with a second limiting groove. Both ends of the second limiting groove are butted against 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.

[0078] In this embodiment, by respectively arranging the first fixed seat 704 and the second fixed seat 711 at both ends of the first base, the first fixed seat 704 and the second fixed 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, so as to respectively limit and guide the positions of the first connecting member 706 and the second connecting member 712, making the sliding of the first connecting member 706 and the second connecting member 712 smoother and more stable.

[0079] Specifically, the first fixed seat 704 is provided with a first fixing hole, and the first base is provided with a first waist-shaped hole extending along the width direction of the first base; the active sliding door mechanism 7 further includes a first adjusting member. The first adjusting member passes through the first fixing hole and is slidably arranged in the first waist-shaped hole to adjust the tightness of the first connecting member 706 by adjusting the position of the first adjusting member in the first waist-shaped hole.

[0080] In this embodiment, by adjusting the position of the first adjusting member in the first waist-shaped hole, the position of the first fixing seat 704 can be adjusted along the width direction of the first base, so that the first fixing seat 704 can tension or relax the first connecting member 706, thereby adjusting the tightness of the first connecting member 706.

[0081] Since the first connecting member 706 and the second connecting member 712 are respectively located on the first fixing seat 704 and the second fixing seat 711 on both sides of the first base, and the first connecting member 706 and the second connecting member 712 are connected to both ends of the first slider 715 and the second slider 709, when the first fixing seat 704 is adjusted to move relative to the first base through the first waist-shaped hole, the tightness of the first connecting member 706 is correspondingly adjusted, and the second connecting member 712 is also correspondingly adjusted in tightness under the pulling of the first fixing seat 704 on the first connecting member 706.

[0082] It can be understood that a first fixing hole can also be provided on the second fixing seat 711; a first waist-shaped hole extending along the width direction of the first base is provided on the first base; the active sliding door mechanism 7 further includes a first adjusting member, the first adjusting member passes through the first fixing hole and is slidably arranged in the first waist-shaped hole to adjust the tightness of the second connecting member 712 by adjusting the position of the first adjusting member in the first waist-shaped hole.

[0083] In this embodiment, by adjusting the position of the first adjusting member in the first waist-shaped hole, the position of the second fixing seat 711 can be adjusted along the width direction of the first base, so that the second fixing seat 711 can tension or relax the second connecting member 712, thereby adjusting the tightness of the second connecting member 712.

[0084] Since the first connecting member 706 and the second connecting member 712 are respectively located on the first fixing seat 704 and the second fixing seat 711 on both sides of the first base, and the first connecting member 706 and the second connecting member 712 are connected to both ends of the first slider 715 and the second slider 709, when the second fixing seat 711 is adjusted to move relative to the first base through the first waist-shaped hole, the tightness of the second connecting member 712 is correspondingly adjusted, and the first connecting member 706 is also correspondingly adjusted in tightness under the pulling of the second fixing seat 711 on the second connecting member 712.

[0085] Furthermore, in some embodiments, a second waist-shaped hole extending along the width direction of the first base is provided on the first fixing seat 704. A second fixing hole is provided on the first base. The active sliding door mechanism 7 further includes a second adjusting member, the second adjusting member passes through the second waist-shaped hole and the second fixing hole in sequence and is fixed in the external structure to adjust the position of the first fixing seat 704 relative to the external structure by the position of the second adjusting member in the second waist-shaped hole.

[0086] In this embodiment, by providing a second waist-shaped hole on the first fixing base 704 and passing the second adjusting member through the second waist-shaped hole and the second fixing hole in sequence to be fixed in the external structure, the first fixing base 704 is fixed in the external structure, so as to fix the active sliding door mechanism 7 on the external structure (such as the box door 2). At the same time, the second adjusting member can be finely adjusted in the position along the second waist-shaped hole, so as to adjust the position of the first fixing base 704, thereby being able to cooperate with adjusting the position of the first fixing base 704 relative to the external structure.

[0087] It can be understood that a second waist-shaped hole extending along the width direction of the first base can also be provided on the second fixing base 711; the second adjusting member passes through the second waist-shaped hole and the second fixing hole in sequence to be fixed in the external structure, so as to adjust the position of the second fixing base 711 relative to the external structure through the position of the second adjusting member in the second waist-shaped hole. The functions of the second adjusting member, the second waist-shaped hole and the second fixing hole are similar to those in the above embodiment and will not be elaborated here.

[0088] In an embodiment of the present application, as Figure 3 and Figure 4 shown, a first rolling gap is formed between the first slider 715 and the first guide rail 710, and a second rolling gap is formed between the second slider 709 and the second guide rail 705; the rolling elements include a first ball 7141 and a second ball 7071, the first ball 7141 is rotatably arranged in the first rolling gap, and the second ball 7071 is rotatably arranged in the second rolling gap.

[0089] 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, it is possible to avoid 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, and rotatably arranged first balls 7141 and second balls 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 through the rolling of the first balls 7141, and the second slider 709 can slide along the second guide rail 705 through the rolling of the second balls 7071, with small friction and smoother sliding.

[0090] In an embodiment of the present application, as Figure 3 and Figure 4 shown, multiple rows of first rolling gaps are formed between the first slider 715 and the first guide rail 710, and multiple rows of second rolling gaps are formed between the second slider 709 and the second guide rail 705; the rolling elements include multiple groups of first balls 7141 and multiple groups of second balls 7071, and each group of first balls 7141 is respectively arranged in each row of the first rolling gaps, and each group of second balls 7071 is respectively arranged in each row of the second rolling gaps.

[0091] In this embodiment, by setting multiple rows of first rolling gaps and arranging a set of first balls 7141 in each row of 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 setting multiple rows of second rolling gaps and arranging a set of second balls 7071 in each row of 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.

[0092] 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.

[0093] In one embodiment of the present application, as Figure 3 shown, both the first rolling gap and the second rolling gap are provided with three rows, and both the first balls 7141 and the second balls 7071 are provided with three sets.

[0094] In this embodiment, by setting three rows of first rolling gaps and second rolling gaps and correspondingly arranging three sets of first balls 7141 and second balls 7071, the first balls 7141 and the second balls 7071 are respectively arranged in three rows between the first slider 715 and the first guide rail 710 and between the second slider 709 and the second guide rail 705, making the sliding of the first slider 715 relative to the first guide rail 710 and the sliding of the second slider 709 relative to the second guide rail 705 more stable and smooth.

[0095] Furthermore, as Figure 3 shown, the first guide rail 710 is provided with three first concave surfaces sequentially arranged along its circumferential direction, a first groove is formed on the first slider 715, and three rows of first rolling gaps are formed between the side wall of the first groove and the three first concave surfaces. The second guide rail 705 is provided with three second concave surfaces sequentially arranged along its circumferential direction, a second groove is formed on the second slider 709, and three rows of second rolling gaps are formed between the side wall of the second groove and the three second concave surfaces.

[0096] In this embodiment, 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 form a first rolling gap therebetween. 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 relative sliding between the first slider 715 and the first guide rail 710. At the same time, the first concave surface can limit the position of the first ball 7141 in the circumferential direction of the first guide rail 710, preventing the first ball 7141 from experiencing circumferential offset on the first guide rail 710 and 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 of the second guide rail 705 form a second rolling gap therebetween. The second concave surface and the second groove respectively abut against both sides of the second ball 7071, enabling the second ball 7071 to roll to achieve relative sliding between the second slider 709 and the second guide rail 705 without circumferential offset and making the sliding of the second slider 709 more stable and smooth.

[0097] 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. This enables the first concave surface and the first groove to better fit the first ball 7141, with a larger force-bearing area and greater stability and reliability during 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, enabling the second concave surface and the second groove to better fit the second ball 7071, with a larger force-bearing area and greater stability and reliability during rolling.

[0098] Optionally, in another embodiment of the present application, as Figure 4 shown, both the first rolling gap and the second rolling gap are provided with four rows, and both the first ball 7141 and the second ball 7071 are provided with four groups.

[0099] In this embodiment, by providing four rows of the first rolling gap and the second rolling gap, and correspondingly providing four groups of the first ball 7141 and the second ball 7071, the first ball 7141 and the second ball 7071 are respectively arranged in four rows between the first slider 715 and the first guide rail 710 and between the second slider 709 and the second guide rail 705, making the sliding of the first slider 715 relative to the first guide rail 710 and the sliding of the second slider 709 relative to the second guide rail 705 more stable and smooth.

[0100] Optionally, the projections of the axes of the four rows of the first rolling gap on the cross-section of the first guide rail 710 are arranged in a square, and are respectively located at the four vertices of the square. The central axis of the first guide rail 710 passes through the center of the square.

[0101] In one embodiment of the present application, as Figure 4 shown, the first guide rail 710 is provided with four first concave surfaces sequentially arranged along its circumferential direction. A first groove is formed on the first slider 715. Four rows of first rolling clearances are formed between the side walls of the first groove and the four first concave surfaces. The second guide rail 705 is provided with four second concave surfaces sequentially arranged along its circumferential direction. A second groove is formed on the second slider 709. Four rows of second rolling clearances are formed between the side walls of the second groove and the four second concave surfaces.

[0102] In this embodiment, 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 clearance. 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 clearance to realize the 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, avoiding the circumferential offset of the first ball 7141 on the first guide rail 710 and 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 of the second guide rail 705 relatively form a second rolling clearance. The second concave surface and the second groove respectively abut against both sides of the second ball 7071, so that the second ball 7071 rolls to realize the relative sliding between the second slider 709 and the second guide rail 705 without circumferential offset, making the sliding of the second slider 709 more stable and smooth.

[0103] In one embodiment of the present application, as Figure 1 and Figure 2 shown, the first guide rail 710 and the second guide rail 705 are arranged in parallel. The first guide rail 710 and the second guide rail 705 are respectively arranged on two opposite sides of the first base.

[0104] In this embodiment, arranging the first guide rail 710 and the second guide rail 705 in parallel is beneficial to reducing the size of the active sliding door mechanism 7 in the length direction of the guide rail while ensuring that the first slider 715 and the second slider 709 have sufficient sliding strokes, making the whole mechanism more compact. At the same time, by arranging the first guide rail 710 and the second guide rail 705 on two opposite sides of the first base respectively, the first slider 715 and the second slider 709 can maintain a certain distance when sliding relatively, avoiding interference between them. The structure is simple, convenient and practical.

[0105] In one embodiment of the present application, as Figure 4As shown, the rolling body further includes: a first support frame 714 and a second support frame 707. The first support frame 714 is arranged 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 arranged in the first limiting notch. The second support frame 707 is arranged 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 arranged in the second limiting notch.

[0106] 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.

[0107] In another embodiment of the present application, Figure 1 , Figure 5 and Figure 6 As shown, a door assembly is provided, comprising: a box door 2, a door panel 21, and an active 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 active 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.

[0108] 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 5 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.

[0109] Specifically, during the process of the door 2 rotating toward the outside of the box body 1 to open (eg Figure 5As shown by the middle arc arrow, under the drive of the box body 1 and the traction mechanism, the first slider 715 slides towards the direction close to the first hinge 4. 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, thus avoiding interference between the door panel 21 and the obstacles outside. Similarly, during the process of the box door 2 rotating and closing towards the box body 1, the active sliding door mechanism 7 drives the door panel 21 to slide towards the direction close to the first hinge 4, thus avoiding interference between the door panel 21 and the obstacles after closing. At the same time, when the slider and the guide rail slide relative to each other, the rolling elements between the slider and the guide rail can convert sliding friction into rolling friction, reducing the frictional force received by the first slider 715 and the second slider 709, and making the sliding smoother.

[0110] For the door body assembly according to the embodiment of the present application, an active sliding door mechanism 7 is provided on the box door 2. The active sliding door mechanism 7 is respectively connected to the box body 1 and the door panel 21 to drive the door panel 21 to slide relative to the width direction of 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. At the same time, the rolling elements of the active sliding door mechanism 7 can reduce the frictional force received by the slider, making the sliding of the door panel 21 smoother.

[0111] It can be understood that if the active sliding door mechanism 7 has the beneficial effects of the above embodiment, the door body assembly correspondingly has the beneficial effects of the above embodiment. The specific implementation manner can refer to the above embodiment, and the present application will not elaborate.

[0112] In an embodiment of the present application, as Figure 6 and Figure 7 shown, the door body assembly further includes: a driven sliding door mechanism 8. The driven sliding door mechanism 8 includes a second base 817 and a third slider 813; a third guide rail is formed on the second base 817, and the third slider 813 is slidably arranged on the third guide rail, and the third slider 813 is connected to the door panel 21.

[0113] In this embodiment, by providing a driven sliding door mechanism 8 on the box door 2, the driven sliding door mechanism 8 has a second base 817. The second base 817 is provided with a third guide rail and a third slider 813 that can slide along the third guide rail. The third slider 813 is connected to the door panel 21. The third slider 813 can slide along with the door panel 21 when the door panel 21 slides relative to the box door 2, playing a supporting and auxiliary role in the sliding of the door panel 21, making the sliding of the door panel 21 relative to the box door 2 smoother. At the same time, the driven sliding door mechanism 8 can cooperate with the active sliding door mechanism 7 to limit the movement direction of the door panel 21, reducing the shaking generated by the door panel 21 during the sliding process and making the sliding more stable.

[0114] Optionally, there can be multiple driven sliding door mechanisms 8. Among them, some of the driven sliding door mechanisms 8 can be coaxially arranged with the active sliding door mechanism 7 on the cabinet door 2; another part of the driven sliding door mechanisms 8 are non-coaxially arranged with the active sliding door mechanism 7 on the cabinet door 2.

[0115] Specifically, the coaxial arrangement of the driven sliding door mechanism 8 and the active sliding door mechanism 7 means sharing the same center line or axis, which helps to ensure that the door panel 21 can maintain a stable linear motion during the sliding process, reducing the possibility of deviation or swing. The coaxial arrangement is used in situations where precise control of the motion direction or maintaining the relative positional relationship between components is required.

[0116] The non-coaxial arrangement of the driven sliding door mechanism 8 and the active sliding door mechanism 7 means that they do not share the same center line or axis. This configuration is used to provide additional support, stability, or prevent the door panel 21 from deflecting around the sliding direction during the sliding process. The non-coaxial arrangement is used in situations where it is necessary to disperse forces, increase stability, or achieve complex motion trajectories.

[0117] In an embodiment of another aspect of the present application, as Figure 5 and Figure 6 shown, a refrigeration device is provided, including: a cabinet 1 and a door assembly as provided in any of the above embodiments. Among them, the cabinet 1 is formed with a plurality of storage spaces, and each door assembly corresponds to one of the storage spaces, so that during the opening or closing process of any cabinet door 2, the door panel 21 is driven to move relative to the corresponding cabinet door 2.

[0118] In this embodiment, the door assembly includes: a cabinet door 2, a door panel 21, and an active sliding door mechanism 7. The active sliding door mechanism 7 is arranged on the cabinet door 2 and is configured to drive the door panel 21 to move relative to the width direction of the cabinet door 2 during the opening or closing process of the cabinet door 2.

[0119] By arranging the door panel 21 on the cabinet 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.

[0120] At the same time, when the cabinet door 2 rotates, the active sliding door mechanism 7 can drive the door panel 21 to move relative to the cabinet door 2 during the rotation of the cabinet door 2 to move as far as possible away from obstacles such as the wall or cabinet on the side of the cabinet 1 of the door panel 21, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the cabinet door 2, resulting in the cabinet door 2 being unable to be normally opened or closed.

[0121] The combination of the box door 2 and the door panel 21 enables the refrigeration equipment 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 even more obvious. In addition, the settings of the slider, guide rail and rolling elements between them in the active sliding door mechanism 7 enable the door panel 21 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0122] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, the refrigeration equipment 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.

[0123] 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 needs. For example, some storage spaces are set as refrigerating chambers, and another part of the storage spaces are set as freezing chambers.

[0124] As Figure 5 shown, based on an application scenario of the above embodiment: The refrigeration equipment can be installed in a trough-shaped structure in the middle of a cabinet. A door panel 21 is provided on the outer side of the box door 2 of the box body 1 of the refrigeration equipment. 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. When the box door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet 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 can maintain visual consistency and have a small gap, making it more beautiful.

[0125] When the box door 2 rotates outward to open, the active sliding door mechanism 7 drives the door panel 21 to slide 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, resulting in the box door 2 being unable to open to a larger angle. When the box door 2 rotates to close, the active sliding door mechanism 7 drives the door panel 21 to slide towards the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side far from the first hinge 4, resulting in the box door 2 being unable to close completely and affecting the refrigeration preservation effect in the storage space. And when the box door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet body again.

[0126] In an embodiment of the present application, as Figure 6 shown, the box body 1 has a first storage space and a second storage space. There are two door body assemblies, namely the first door body assembly and the 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.

[0127] In this embodiment, a first storage space and a second storage space are provided on the box body 1 to separately store the items to be stored according to requirements. A first door assembly and a second door assembly are respectively provided corresponding to the first storage space and the second storage space, so that when the box doors 2 of the first door assembly and the second door assembly are rotated and opened or closed, the corresponding door panels 21 can slide relative to the box doors 2 to avoid obstacles.

[0128] In a specific embodiment of the present application, three groups of first balls 7141 and / or second balls 7071 are provided for the first door assembly, and four groups of first balls 7141 and / or second balls 7071 are provided for the second door assembly. The weight of the second door assembly is greater than that of the first door assembly.

[0129] In this embodiment, three groups of first balls 7141 and / or second balls 7071 are provided for the first door assembly to carry the first door assembly with a lighter weight, making the structure more compact. Four groups of first balls 7141 and / or second balls 7071 are provided for the second door assembly to carry the first door assembly with a lighter weight, making the structure more stable and reliable.

[0130] 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 within the scope of the claims of the present invention.
