[0048] Combine the following Figures 1 to 31 The sliding door mechanism, door assembly and refrigeration device of the present application are described. The sliding door mechanism and door assembly in 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 in the present application can also be applied to a dishwasher, a washing machine or any other suitable device. The refrigeration device in the present application is applied to a refrigerator, for example, but it should be understood that the refrigeration device in the present application can also be applied to a freezer or any other suitable device.

[0049] In one embodiment of the present application, Figures 1 to 5As 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 the box door 2 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 includes: a first base 717, a first slider 714, a second slider 713 and a flexible cable 706. A first guide rail is formed on one side of the first base 717, and a second guide rail is formed on the other side. The first slider 714 is slidably arranged on the first guide rail, and the traction component is rotatably connected between the box body 1 and the first slider 714. The second slider 713 is slidably arranged on the second guide rail for connecting with the door panel 21. The two ends of the flexible cable 706 are respectively connected to the first slider 714 and the second slider 713. When the first slider 714 moves on the first guide rail, the first slider 714 drives the second slider 713 to move in the opposite direction on the second guide rail through the flexible cable 706 to drive the door panel 21 to move relative to the width direction of the box door 2 .

[0050] It can be understood that the sliding door mechanism 7 of the present embodiment can be arranged on the box door 2, one of the first slider 714 and the second slider 713 is transmission-connected to the box door 2 or the box body 1, and the other is slidingly connected to the door panel 21 arranged on the outside of the box door 2, so that when the box door 2 rotates, the first slider 714 and the second slider 713 slide relative to each other 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 open and close.

[0051] Specifically, taking the first slider 714 connected to the box body 1 through the traction component and the second slider 713 connected to the door panel 21 as an example, the first base 717 of this embodiment can be set on the box door 2. The two ends of the flexible cable 706 are respectively connected to the first slider 714 and the second slider 713, so that the first slider 714 can pull the second slider 713 to move synchronously through the flexible cable 706, thereby driving the door panel 21 to slide relative to the box door 2.

[0052] By properly setting the extension direction of the flexible cable 706 , the first slider 714 and the second slider 713 move in opposite directions during movement, so as to drive the door panel 21 to avoid obstacles.

[0053] For example, when the door 2 is rotated to the outside of the box body 1 to open, the door 1 drives the first slider 714 to slide in the direction close to the first hinge 4 through the traction component, and at the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., away from the first hinge 4) through the flexible cable 706, 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 714 to slide in the direction away from the first hinge 4, and at the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., close to the first hinge 4) through the flexible cable 706, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0054] It is understandable that the first slider 714 can also be connected to the door panel 21, and correspondingly, the second slider 713 is connected to the box door 2 or the box body 1 through a traction component. The working process is the same as that of the above embodiment and will not be repeated here.

[0055] According to the sliding door mechanism 7 of the present application, a first guide rail and a second guide rail are arranged on both sides of a first base 717, and a first slider 714 and a second slider 713 are slidably arranged on the first guide rail and the second guide rail, respectively. The first slider 714 and the second slider 713 can slide synchronously along the guide rails under the transmission of the flexible rope 706, and the sliding directions are opposite. One of the first slider 714 and the second slider 713 is connected to the door 2 or the box body 1 through a traction component, and the other is connected to the door panel 21 arranged on the outside of the door 2, so that when the door 2 rotates, the two sliders slide relative to each other to drive the door panel 21 to slide relative to the door 2, so that the door panel 21 can avoid obstacles on both sides during the process of the door 2 turning on and off.

[0056] It should be noted that, in practical applications, the designs of the first slider 714 and the second slider 713 can be flexible and adaptable 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.

[0057] From the material point of view, the first slider 714 and the second slider 713 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 sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0058] In terms of structural design, the first slider 714 and the second slider 713 can adopt various forms of guide rail contact surfaces, such as plane contact, ball contact or sliding bearing contact. 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.

[0059] In addition, in order to enhance the bearing capacity and stability of the slider, reinforcing ribs, support plates or other auxiliary structures may be added to the first slider 714 and the second slider 713. These structures can increase the rigidity and anti-deformation ability of the slider, ensuring stable sliding performance when bearing the weight of the door panel 21 and external forces.

[0060] In this embodiment, the first guide rail and the second guide rail are arranged in sequence along the width direction of the first base 717, and the first guide rail and the second guide rail are arranged in parallel along the width direction of the first base 717. While ensuring that the length of the first guide rail and the second guide rail can meet the sliding distance of the first slider 714 and the second slider 713, the dimensions of the first base 717 in the height direction and the thickness direction can be effectively reduced, and the structure is more compact and occupies less space.

[0061] In practical applications, due to factors such as machine tool accuracy, tool wear, and material non-uniformity, there will be certain errors in the processing of the first guide rail, the second guide rail, and the base. These errors may include dimensional errors (such as deviations in length, width, and height), shape errors (such as straightness, flatness, roundness, etc.), and position errors (such as coaxiality, parallelism, and verticality). The parallelism between the first and second guide rails is evaluated by measuring the relative position deviation between them. This deviation needs to be controlled within a certain tolerance range to ensure smooth sliding of the slider and stable operation of the system. This tolerance range is usually determined based on design requirements, usage environment, and system accuracy.

[0062] It should be noted that in this embodiment, parallelism and verticality should not be strictly defined in a geometric sense. At least the manufacturing and installation errors should be considered, and the errors of plus or minus 10° should be understood as within the scope of protection of the patent.

[0063] In one embodiment of the present application, Figure 3 , Figure 4 and Figure 5 As shown, the flexible cable 706 includes: a first flexible cable and a second flexible cable. The first flexible cable passes around one end of the first base 717, and both ends are respectively connected to one end of the first slider 714 and the second slider 713; the second flexible cable passes around the other end of the first base 717, and both ends are respectively connected to the other ends of the first slider 714 and the second slider 713.

[0064] In this embodiment, one end of the first flexible rope is passed around the first base 717 and connected to the first slider 714 and the second slider 713 respectively. When the first slider 714 slides in the direction away from the end of the first base 717 driven by the box door 2 or the box body 1 through the traction component, the first slider 714 drives the second slider 713 to slide in the direction close to the end of the first base 717 through the first flexible rope. At the same time, the other end of the second flexible rope is passed around the first base 717 and connected to the first slider 714 and the second slider 713 respectively. When a slider 714 slides toward the other end away from the first base 717 under the drive of the box door 2, the first slider 714 drives the second slider 713 to slide toward the other end close to the first base 717 through the second flexible rope, thereby achieving that when the first slider 714 slides toward both ends of the first base 717 respectively, the second slider 713 and the first slider 714 can be driven to slide in the opposite direction, thereby enabling 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 affecting the opening and closing of the box door 2.

[0065] The flexible rope 706 is one of steel wire rope, steel strand or hemp rope. The flexible rope 706 is selected according to the load, working environment and use requirements that it needs to bear. For occasions that need to withstand large loads and harsh environments, it is recommended to choose steel wire rope or steel strand; for occasions with small loads and mild environments, hemp rope can be considered. On the premise of meeting the use requirements, consider the cost differences of different materials and choose the most cost-effective material. In addition, steel wire rope and steel strand may need regular inspection and maintenance during use to ensure their performance and safety; hemp rope is relatively easy to replace and maintain.

[0066] Specifically, the second slider 713 and the first slider 714 are both provided with a connector 711 for fixing the flexible cable 706 .

[0067] In one embodiment of the present application, Figure 3 , Figure 4 and Figure 5 As shown, the sliding door mechanism 7 also includes: a first fixed seat 701 and a second fixed seat 702, the first fixed seat 701 is connected to one end of the first base 717, and a first limiting groove is formed, and both ends of the first limiting groove are connected to one end of the first guide rail and the second guide rail, and a part of the first flexible cable can be slidably set in the first limiting groove; the second fixed seat 702 is connected to the other end of the first base 717, 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 and the second guide rail, and a part of the second flexible cable can be slidably set in the second limiting groove.

[0069] Specifically, a first fixing hole is provided on the first fixing seat 701, and a first waist-shaped hole extending along the width direction of the first base 717 is provided on the first base 717; the sliding door mechanism 7 also includes a first adjusting member 704, and the first adjusting member 704 passes through the first fixing hole and is slidably arranged in the first waist-shaped hole to adjust the tightness of the first flexible rope by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0070] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the first fixing seat 701 can be adjusted along the width direction of the first base 717, so that the first fixing seat 701 can tighten or loosen the first flexible rope, thereby adjusting the tightness of the first flexible rope.

[0071] Since the first flexible cable and the second flexible cable are respectively located on the first fixed seat 701 and the second fixed seat 702 on both sides of the first base 717, and the first flexible cable and the second flexible cable are connected to the first slider 714 and the second slider 713 at both ends, when the first fixed seat 701 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the first flexible cable is adjusted in tightness accordingly, and the second flexible cable is also adjusted in tightness accordingly under the pulling of the first fixed seat 701 on the first flexible cable.

[0075] Further, in some embodiments, the first fixing seat 701 is provided with a second waist-shaped hole extending in the width direction of the first base 717. The first base 717 is provided with a second fixing hole. The sliding door mechanism 7 also includes a second adjusting member 703, which passes through the second waist-shaped hole and the second fixing hole in sequence and is fixed in the external structure, so as to adjust the position of the first fixing seat 701 relative to the external structure through the position of the second adjusting member 703 in the second waist-shaped hole.

[0076] In this embodiment, the first fixing seat 701 is provided with a second waist-shaped hole, and the second adjusting member 703 is sequentially passed through the second waist-shaped hole and the second fixing hole to be fixed in the external structure, so that the first fixing seat 701 is fixed in the external structure, so that the sliding door mechanism 7 is fixed on the external structure (such as the box door 2). At the same time, the second adjusting member 703 can be fine-tuned in the position along the second waist-shaped hole to adjust the position of the first fixing seat 701, so as to cooperate with the adjustment of the position of the first fixing seat 701 relative to the external structure.

The functions of the second adjusting member 703, the second waist-shaped hole and the second fixing hole are similar to those in the above embodiment and are not described in detail here.

[0078] Furthermore, in some embodiments, a rotatable support bearing is provided in the first limit groove; a portion of the first flexible cable abuts against the support bearing in the first limit groove. In this embodiment, by abutting a portion of the first flexible cable against the support bearing, the activity of the first flexible cable and its extension direction can be adjusted, so that the first flexible cable can be connected to the first slider 714 and the second slider 713 around the end of the first base 717.

[0079] It is understandable that a rotatable support bearing may also be provided in the second limit groove; a portion of the second flexible cable abuts against the support bearing in the second limit groove to adjust the extension direction of the second flexible cable, making it convenient to connect the second flexible cable around the end of the first base 717 and the first slider 714 and the second slider 713.

[0080] Specifically, in some embodiments, the support bearing includes a first bearing 705 and a second bearing 716 , which are respectively located at one end of the same side of the first guide rail and the second guide rail and are respectively located on both sides of the first base 717 .

[0081] In one embodiment of the present application, Figures 3 to 5 As shown, the traction component includes a traction rod 709, a first rotating shaft fixing seat 707 and a second rotating shaft fixing seat 710.

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 714 is pulled through the transmission connection of the traction rod 709, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, so that the first slider 714 slides on the first base 717, and drives the second slider 713 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0083] Specifically, one end of the traction rod 709 is rotatably connected to the first rotating shaft fixing seat 707 via a pin shaft 708 and a third bearing 715 , and the other end is rotatably connected to the second rotating shaft fixing seat 710 via another pin shaft 708 and another third bearing 715 .

Similarly, when the box door 2 rotates toward one side of the box body 1 to close, the sliding door mechanism 7 drives the door panel 21 to slide toward the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles after closing.

The third slider 813 can slide with the door panel 21 when the door panel 21 slides relative to the box door 2, and plays a supporting and auxiliary role in the sliding of the door panel 21, so that the door panel 21 can slide more smoothly relative to the box door 2. At the same time, the first driven guide rail mechanism 8 can cooperate with the sliding door mechanism 7 to limit the movement direction of the door panel 21, reduce the shaking of the door panel 21 during the sliding process, and slide more stably. In addition, the slot on the second connecting block 812 can facilitate the user to install the door panel 21 on the driven guide rail mechanism.

At the same time, the second connecting block 812 can cooperate with the sliding door mechanism 7 to limit the movement direction of the door panel 21, so as to prevent the door panel 21 from swinging during the movement. At the same time, since the second driven guide rail mechanism 9 and the sliding door mechanism 7 are arranged in a different axis, the third connecting block 905 can cooperate with the sliding door mechanism 7 to limit the movement direction of the door panel 21, so as to prevent the door panel 21 from deflecting around the sliding direction when sliding, and the sliding process is more stable and reliable.

[0134] In one embodiment of the present application, Figure 2 As shown, the door assembly and the cabinet 1 are used to be arranged in an installation space formed between a first cabinet and a second cabinet; during the opening or closing process of the cabinet door 2, the sliding door mechanism 7 is configured to drive the door panel 21 to move a preset distance on the cabinet door 2 so that the door panel 21 avoids the side walls of the first cabinet and the second cabinet.

[0135] In this embodiment, the box body 1 is arranged between the first cabinet body and the second cabinet body. It can be understood that 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 body. When the box door 2 is closed, the door panel 21 is flush with the outer walls of the first cabinet body and the second cabinet body on both sides, so that the door panel 21 and the outer wall of the cabinet body can maintain visual consistency with a smaller gap, which is more beautiful.

[0136] When the door 2 is rotated outward to open, the sliding door mechanism 7 drives the door panel 21 to slide a preset distance 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, resulting in the door 2 being 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 a preset distance 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, resulting in the door 2 being unable to be completely closed and affecting the function of the cabinet 1, and when the door 2 is completely closed, the door panel 21 can be restored to a state flush with the cabinet. By designing a reasonable preset distance, it is possible to avoid interference between the door panel 21 and the cabinet walls on both sides when sliding relative to the door 2.

[0137] In another embodiment of the present application, the door assembly and the box body 1 are used to be arranged in a cabinet; during the opening or closing process of the box door 2, the sliding door mechanism 7 is configured to drive the door panel 21 to move a preset distance on the box door 2 so that the door panel 21 avoids the side wall of the cabinet.

[0138] In this embodiment, the box body 1 is arranged in a single cabinet.
