[0031] The following is combined with Figures 1 to 6 This application describes a door assembly and a refrigeration device. The door assembly can be applied to household appliances, such as refrigerators; however, it should be understood that the door assembly can also be applied to dishwashers, washing machines, or any other suitable equipment. The refrigeration device can be applied, for example, to a refrigerator; however, it should be understood that the refrigeration device can also be applied to a freezer or any other suitable equipment.

[0032] In one embodiment of this application, such as Figures 1 to 4As shown, this door assembly is used in refrigeration equipment. The refrigeration equipment includes a cabinet 4, and the door assembly includes a door 2, a door panel 3, a traction mechanism 9, and a first sliding door mechanism 1. The door 2 is rotatably connected to the cabinet 4 of the refrigeration equipment and is suitable for opening or closing the storage space of the cabinet 4. A first mounting groove 21 is provided on the outer side of the door 2. The door panel 3 is slidably disposed on the outer side of the door 2. The first sliding door mechanism 1 is disposed in the first mounting groove 21. One end of the first sliding door mechanism 1 is connected to the cabinet 4 via the traction mechanism 9, and the other end of the first sliding door mechanism 1 is connected to the door panel 3. During the opening or closing of the door 2, the traction mechanism 9 drives the first sliding door mechanism 1, causing the first sliding door mechanism 1 to drive the door panel 3 to move relative to the width direction of the door 2.

[0033] In this embodiment, a first mounting groove 21 is designed on the outer side of the door 2 to accommodate the first sliding door mechanism 1. The first mounting groove 21 provides the installation position and space for the first sliding door mechanism 1. To allow the door panel 3 to avoid obstacles such as side walls and objects, the door panel 3 is slidably mounted on the outer side of the door 2. The traction mechanism 9 is mainly used to connect the box body 4 and the first sliding door mechanism 1, and is used to transmit power, responsible for converting the movement of the box body 4 (such as opening or closing) into the driving force of the first sliding door mechanism 1.

[0034] When the user rotates the door 2, the traction mechanism 9, driven by the relative movement between the door 2 and the box body 4, drives the first sliding door mechanism 1 to perform a corresponding action. The first sliding door mechanism 1 is disposed in the first mounting groove 21 on the outside of the door 2. One end of the first sliding door mechanism 1 is connected to the box body 4 via the traction mechanism 9, and the other end is connected to the door panel 3. In this way, when the door 2 is opened or closed, the first sliding door mechanism 1 can receive the driving force from the traction mechanism 9 and drive the door panel 3 to move relative to the width direction of the door 2 to avoid obstacles such as side walls and objects.

[0035] According to an embodiment of the present invention, by placing the first sliding door mechanism 1 in the first mounting groove 21 on the outside of the door 2, the first sliding door mechanism 1 can be hidden within the entire door assembly. One end of the first sliding door mechanism 1 is connected to the housing 4 via a traction mechanism 9, and the other end of the first sliding door mechanism 1 is connected to the door panel 3, so that during the opening or closing of the door 2, the first sliding door mechanism 1 drives the door panel 3 to move relative to the width direction of the door 2, allowing the door panel 3 to avoid obstacles such as side walls and objects.

[0036] In some embodiments, such as Figures 1 to 4As shown, the first sliding door mechanism 1 is vertically arranged in the first mounting groove 21. The first sliding door mechanism 1 includes: a first base 13, a first slider 11, a second slider 12, and a first connecting member. A first guide rail 131 is formed on the upper side of the first base 13, and a second guide rail 132 is formed on the lower side. The first slider 11 is slidably arranged on the first guide rail 131 and is used for transmission connection with the housing 4 through the traction mechanism 9. The second slider 12 is slidably arranged on the second guide rail 132 and is connected to the door panel 3. The two ends of the first connecting member are respectively connected to the first slider 11 and the second slider 12. When the first slider 11 moves on the first guide rail 131, the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the first connecting member, so as to drive the door panel 3 to move relative to the width direction of the housing door 2.

[0037] Specifically, such as Figure 2 and Figure 3 As shown, the first guide rail 131 is located on the upper side of the first base 13, providing a sliding track for the first slider 11. The second guide rail 132 is located on the lower side of the first base 13, parallel to or at a certain angle to the first guide rail 131, providing a sliding track for the second slider 12. The first slider 11 is slidably mounted on the first guide rail 131 and is connected to the housing 4 via a transmission connection. The second slider 12 is slidably mounted on the second guide rail 132 and is connected to the door panel 3. The two ends of the first connecting member are respectively connected to the first slider 11 and the second slider 12.

[0038] When the door 2 is opened or closed, the relative movement between the box body 4 and the door 2 causes the first slider 11 to move on the first guide rail 131 under driving force. Since the two ends of the first connector are fixed to the first slider 11 and the second slider 12 respectively, by reasonably setting the extension direction of the first connector, the first connector will drive the second slider 12 to move in the opposite direction on the second guide rail 132. This characteristic of synchronous and opposite movement allows the door panel 3 to slide relative to the width direction of the box body 4.

[0039] The first sliding door mechanism 1 provided by the present invention includes a first slider 11 and a second slider 12 respectively set on a first guide rail 131 and a second guide rail 132, and a first connector connecting the first slider 11 and the second slider 12. When the first slider 11 moves, it can drive the second slider 12 to move in the opposite direction. Thus, when the first slider 11 is connected to the housing 4 and the second slider 12 is connected to the door panel 3, the first sliding door mechanism 1 can drive the door panel 3 to slide relative to the width direction of the housing door 2. This allows the door panel 3 to avoid obstacles such as side walls and objects during the closing or opening of the housing door 2, thereby meeting the user's needs in different scenarios.

[0040] It should be noted that in practical applications, the design of the first slider 11 and the second slider 12 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.

[0041] From a materials perspective, the first slider 11 and the second slider 12 can be made of materials with high wear resistance, low coefficient of friction, 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 sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0042] In terms of structural design, the first slider 11 and the second slider 12 can adopt various forms of guide rail contact surfaces, such as planar contact, ball contact, or sliding bearing contact. Each of these different contact methods has its advantages and disadvantages. For example, ball contact can reduce friction and wear, but it is more expensive; while planar contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness, and ease of maintenance should be comprehensively considered when making a selection.

[0043] In addition, to enhance the load-bearing capacity and stability of the sliders, reinforcing ribs, support plates, or other auxiliary structures can be added to the first slider 11 and the second slider 12. These structures can increase the rigidity and deformation resistance of the sliders, ensuring stable sliding performance when bearing the weight of the door panel 3 and external forces.

[0044] In some embodiments, such as Figure 5 As shown, the first connector includes a first flexible cable and a second flexible cable, which can be ropes. The first flexible cable passes over one end of the first base 13, and its two ends are respectively connected to one end of the first slider 11 and the second slider 12; the second flexible cable passes over the other end of the first base 13, and its two ends are respectively connected to the other ends of the first slider 11 and the second slider 12.

[0045] Specifically, one end of the first flexible cable is fixed to a predetermined position of the first slider 11, then passes around a specific part of the first base 13 (such as a pulley or guide device on the base), and finally connects to the corresponding position of the second slider 12. In this way, when the first slider 11 moves on the first guide rail 131, the first flexible cable can smoothly transmit this movement and drive the second slider 12 to move in the opposite direction on the second guide rail 132.

[0046] Similarly, the second flexible cable also loops around the other end of the first base 13, but along a different path than the first flexible cable, to ensure balance and stability between the two sliders. One end of the second flexible cable is fixed to another predetermined position on the first slider 11 (opposite to the connection point of the first flexible cable), loops around the other side of the first base 13, and finally connects to the other end of the second slider 12. This double flexible cable design not only enhances the reliability of the connection but also makes the entire first sliding door mechanism 1 more stable and smooth during operation.

[0047] The performance of the sliding door mechanism can be further optimized by adjusting the bypass paths and fixed points of the first and second flexible cables on the first base 13. For example, the tension of the first and second flexible cables can be adjusted to ensure the synchronicity and consistency of the first slider 11 and the second slider 12 during movement.

[0048] In this embodiment, as Figures 1 to 4 As shown, the first mounting groove 21 is located on the outside of the door 2, and the first sliding door mechanism 1 is vertically arranged in the first mounting groove 21. Compared with the horizontal arrangement of the first sliding door mechanism 1, the depth of the first mounting groove 21 can be reduced to a certain extent, which can reduce the thickness of the door 2. The first guide rail 131 and the second guide rail 132 are arranged parallel to each other. This arrangement not only enhances the stability and load-bearing capacity of the first sliding door mechanism 1, but also makes the movement of the first slider 11 and the second slider 12 more stable and smooth. The first guide rail 131 faces upward, which makes it easier for the first slider 11 on the first guide rail 131 to connect with the traction mechanism 9. The traction mechanism 9 is usually located near the top of the box body 4. The second guide rail 132 faces downward, opposite to the first guide rail 131, and cooperates to connect the door panel 3.

[0049] In some embodiments, a first ball and a first support member are provided between the first slider 11 and the first guide rail 131 and between the second slider 12 and the second guide rail 132. The first support member is provided with a first rolling notch, and the first ball is rotatably disposed in the first rolling notch.

[0050] In this embodiment, a first support frame is provided between the first slider 11 and the first guide rail 131, and the second slider 12 and the second guide rail 132 are supported by the first support frame to limit the first ball, prevent the first ball from deviating when rolling, and make the sliding of the first slider 11 and the second slider 12 more stable and reliable.

[0051] Specifically, the first rolling notch is an arc-shaped notch that matches the shape of the first ball. By setting the arc-shaped notch, the limiting effect on the first ball is improved. Moreover, when the first rolling notch contacts the first ball, the force-bearing area is larger and the force is more dispersed, which can reduce the wear between the first support frame and the first ball and extend the service life.

[0052] In some embodiments, such as Figures 1 to 4 As shown, the outer side of the door 2 is provided with a second mounting groove 22; the door assembly also includes: a second sliding door mechanism 10 and a connecting rod 8; the second sliding door mechanism 10 is disposed in the second mounting groove 22, one end of the second sliding door mechanism 10 is connected to the first slider 11 through the connecting rod 8, and the other end of the second sliding door mechanism 10 is connected to the door panel 3. The second sliding door mechanism 10 is configured to cooperate with the first sliding door mechanism 1 to drive the door panel 3 to move relative to the width direction of the door 2 during the opening or closing of the door 2.

[0053] Specifically, a second mounting groove 22 is provided on the outer side of the door 2, providing installation space for the second sliding door mechanism 10. The main function of the second sliding door mechanism 10 is to cooperate with the first sliding door mechanism 1. During the opening or closing of the door 2, the second sliding door mechanism 10 also drives the door panel 3 to move relative to the width direction of the door 2. The connecting rod 8, as a component connecting the second sliding door mechanism 10 and the first slider 11, plays the role of transmitting force and motion. When the second sliding door mechanism 10 is driven by the first slider 11 on the first sliding door mechanism 1, the second sliding door mechanism 10 can cooperate to drive the door panel 3 to move. This design allows the door panel 3 to be further driven by the second sliding door mechanism 10 on the basis of the first sliding door mechanism 1, increasing the driving force when the door panel 3 moves and increasing the stability of the door panel 3 when moving relative to the door 2.

[0054] In some embodiments, such as Figures 1 to 4 As shown, the second sliding door mechanism 10 is vertically arranged in the second mounting groove 22, including: a second base 101, a third slider 102, a fourth slider 103, and a second connecting member. A third guide rail 1011 is formed on the upper side of the second base 101, and a fourth guide rail 1012 is formed on the lower side; the third slider 102 is slidably arranged on the third guide rail 1011, and the third slider 102 is connected to the first slider 11 through a connecting rod 8; the fourth slider 103 is slidably arranged on the fourth guide rail 1012 for connecting to the door panel 3; the two ends of the second connecting member are connected to the third slider 102 and the fourth slider 103 respectively; during the opening or closing of the door 2, the third slider 102 and the fourth slider 103 move in opposite directions to drive the door panel 3 to move relative to the width direction of the door 2.

[0055] In this embodiment, the second base 101 serves as the main body of the second sliding door mechanism 10, providing a stable mounting base and sliding track. The third guide rail 1011 formed by the second base 101 is the sliding path of the third slider 102, and the fourth guide rail 1012 is the sliding path of the fourth slider 103. The third slider 102 is slidably mounted on the third guide rail 1011 and is driven by the first slider 11 via the connecting rod 8. The fourth slider 103 is slidably mounted on the fourth guide rail 1012 and connected to the door panel 3.

[0056] During the sliding process, the third slider 102 is driven by the connecting rod 8 to move linearly along the third guide rail 1011, thereby driving the fourth slider 103 to move, causing the door panel 3 to move accordingly. The connecting rod 8 connects the first slider 11 and the third slider 102, enabling the second sliding door mechanism 10 to receive the driving force from the first sliding door mechanism 1 and transmit this force to the door panel 3, driving it to move.

[0057] In this embodiment, as Figures 2 to 5 As shown, the second mounting groove 22 is located on the outside of the door 2, and the second sliding door mechanism 10 is vertically arranged in the second mounting groove 22. The third guide rail 1011 is coaxially arranged with the first guide rail 131, and the third guide rail 1011 and the fourth guide rail 1012 are arranged parallel to each other, so that when the first slider 11 moves on the first guide rail 131, the connecting rod 8 drives the third slider 102 to move synchronously on the third guide rail 1011, so that the position of the first slider 11 and the third slider 102 can be adjusted by a single traction mechanism 9, so that the door panel 3 can move under the drive of the second slider 12 and the fourth slider 103.

[0058] To facilitate the installation of the first sliding door mechanism 1, the second sliding door mechanism 10, and the connecting rod 8, such as Figures 1 to 3 As shown, the door 2 is provided with a third mounting groove 23, which is connected to the first mounting groove 21 and the second mounting groove 22. A part of the connecting rod 8 is movably disposed in the third mounting groove 23; one end of the connecting rod 8 is located in the first mounting groove 21 and is connected to the second slider 12; the other end of the connecting rod 8 is located in the second mounting groove 22 and is connected to the third slider.

[0059] In practical applications, due to factors such as machine tool precision, tool wear, and material inhomogeneity, the machining of the first guide rail 131, second guide rail 132, third guide rail 1011, fourth guide rail 1012, first base 13, and second base 101 may contain certain errors. These errors may include dimensional errors (such as deviations in length, width, and height), shape errors (such as straightness, flatness, and roundness), and positional errors (such as coaxiality, parallelism, and perpendicularity). The parallelism between the first guide rail 131 and the second guide rail 132 is evaluated by measuring their relative positional deviation. This deviation needs to be controlled within a certain tolerance range to ensure smooth sliding of the corresponding sliders and stable operation of the system.

[0060] In other words, the direction of the guide rail in this embodiment, whether it is parallel or perpendicular, should not be strictly geometric. At least manufacturing and installation errors should be taken into account, and an error of ±10° should be understood as being within the scope of patent protection.

[0061] In one example, a second ball and a second support are provided between the third slider 102 and the third guide rail 1011 and between the fourth slider 103 and the fourth guide rail 1012. The second support is provided with a second rolling notch, and the second ball is rotatably disposed in the second rolling notch.

[0062] In this embodiment, by providing a second support frame between the third slider and the third guide rail 1011 and between the fourth slider 103 and the fourth guide rail 1012, the second support frame is used to limit the second ball bearing, preventing the second ball bearing from shifting during rolling, thus making the sliding of the third slider more stable and reliable.

[0063] Typically, the second rolling notch is an arc-shaped notch that matches the shape of the second ball. By setting an arc-shaped notch, the limiting effect on the second ball is improved. Moreover, when the second rolling notch contacts the second ball, the force-bearing area is larger and the force is more dispersed, which can reduce the wear between the second support frame and the second ball and extend the service life.

[0064] In this embodiment, the connecting rod 8, as a key component connecting the first sliding door mechanism 1 and the second sliding door mechanism 10, is crucially positioned. In this embodiment, a portion of the connecting rod 8 is movably disposed in the third mounting groove 23. This design allows the connecting rod 8 to flexibly adapt to changes in the relative positions of the components in the first and second sliding door mechanisms 10 during movement, ensuring the stability and reliability of the connection. One end of the connecting rod 8 is located in the first mounting groove 21 and is tightly connected to the first slider 11 in the first sliding door mechanism 1. Thus, when the first sliding door mechanism 1 is subjected to a driving force, this force can be transmitted to the second sliding door mechanism 10 through the connecting rod 8. Simultaneously, the other end of the connecting rod 8 is located in the second mounting groove 22 and is connected to the third slider 102 in the second sliding door mechanism 10. In this way, the second sliding door mechanism 10 can receive the driving force from the first sliding door mechanism 1 and cooperate with the drive door panel 3 to move accordingly. The interconnected design of the third mounting groove 23 for housing the connecting rod 8 ensures a stable and smooth connection between the components, improving the stability and reliability of the entire door assembly. Furthermore, the arrangement of the third mounting slot 23 makes the layout of components such as the first sliding door mechanism 1, the second sliding door mechanism 10, and the connecting rod 8 more reasonable and compact, saving space inside the door 2.

[0065] In one embodiment of this application, such as Figures 1 to 4 As shown, the two ends of the traction mechanism 9 are rotatably connected to the housing 4 and the first slider 11, respectively. Specifically, the traction mechanism 9 includes a traction rod, a first rotating shaft fixing seat, and a second rotating shaft fixing seat. The traction rod can be a straight guide rod or a curved guide rod, which can be adjusted according to specific needs. The first rotating shaft fixing seat is connected to the first slider 11, and the second rotating shaft fixing seat is used to connect to the housing 4. One end of the traction rod is rotatably connected to the first rotating shaft fixing seat, and the other end of the traction rod is rotatably connected to the second rotating shaft fixing seat.

[0066] In this embodiment, by fixing the first rotating shaft fixing seat and the second rotating shaft fixing seat to the first slider 11 and the box body 4 respectively, and connecting the first rotating shaft fixing seat and the second rotating shaft fixing seat through a traction rod, when the box door 2 rotates relative to the box body 4, the angle between the box body 4 and the box door 2 changes, thereby pulling the first slider 11 through the transmission connection of the traction rod, the first rotating shaft fixing seat and the second rotating shaft fixing seat, so that the first slider 11 slides on the first base 13, and drives the second slider 12 to slide to realize the movement of the door panel 3 relative to the box door 2.

[0067] In some embodiments, such as Figure 4As shown, a fourth mounting groove 24 is also provided on the outer side of the door panel 3, and the door assembly also includes a driven guide rail mechanism 14. The driven guide rail mechanism 14 is disposed in the fourth mounting groove 24, and is connected to the door panel 3. It is configured to guide the door panel 3 to move relative to the width direction of the door 2 during the opening or closing process of the door 2.

[0068] Specifically, the fourth mounting slot 24 provides mounting space for the driven guide rail mechanism 14. The main function of the driven guide rail mechanism 14 is to guide the door panel 3 to move relative to the width direction of the door 2 during the opening or closing process. This design allows the door panel 3 to be further guided by the driven guide rail mechanism 14 on the basis of the first sliding door mechanism 1 and the second sliding door mechanism 10, thereby increasing the smoothness of the door panel 3 when moving relative to the door 2.

[0069] The driven guide rail mechanism 14 includes a third base and a fifth slider. A fifth guide rail is formed on the outer side of the third base; the fifth slider is slidably mounted on the fifth guide rail. In this embodiment, the fifth base serves as the main body of the driven guide rail mechanism 14, and the third base provides a stable mounting base and sliding track. The fifth guide rail formed by the fifth base is the sliding path of the fifth slider. The fifth slider is directly connected to the door panel 3. During sliding, the fifth slider moves linearly along the fifth guide rail, thereby causing the door panel 3 to move accordingly. Since the fifth slider is directly connected to the door panel 3, its sliding performance and stability directly affect the movement effect of the door panel 3.

[0070] Based on the above embodiments, in some embodiments, one of the first mounting groove 21 and the fourth mounting groove 24 is disposed at the top of the outer side of the door 2, and the other is disposed at the bottom of the outer side of the door 2.

[0071] Generally, the first mounting slot 21, the second mounting slot 22, and the third mounting slot 23 are all located on the top of the outer side of the door 2, for mounting the first sliding door mechanism 1, the second sliding door mechanism 10, and the connecting rod 8. The fourth mounting slot 24 is located at the bottom of the outer side of the door 2, for mounting the driven guide rail mechanism 14. By simultaneously mounting the first sliding door mechanism 1, the second sliding door mechanism 10, the connecting rod 8, and the driven guide rail mechanism 14, the upper part of the door panel 3 is driven by the first sliding door mechanism 1 and the second sliding door mechanism 10, and the lower part of the door panel 3 is guided by the driven guide rail mechanism 14, so that the door panel 3 can operate stably during the sliding process relative to the width direction of the door 2.

[0072] In another embodiment of this application, such as Figures 1 to 6As shown, a refrigeration device is provided, including: a housing 4 and a door assembly as provided in any of the above embodiments. The housing 4 forms a storage space, and a door 2 is rotatably connected to the housing 4, suitable for opening or closing the storage space. The door assembly, applied to the refrigeration device, includes: a door 2, a door panel 3, a traction mechanism 9, and a first sliding door mechanism 1. The door 2 is rotatably connected to the housing 4, suitable for opening or closing the storage space of the housing 4, and a first mounting groove 21 is provided on the outer side of the door 2; the door panel 3 is slidably disposed on the outer side of the door 2; the first sliding door mechanism 1 is disposed in the first mounting groove 21, one end of the first sliding door mechanism 1 is connected to the housing 4 via the traction mechanism 9, and the other end of the first sliding door mechanism 1 is connected to the door panel 3. During the opening or closing of the door 2, the traction mechanism 9 drives the first sliding door mechanism 1, causing the first sliding door mechanism 1 to drive the door panel 3 to move relative to the width direction of the door 2.

[0073] Specifically, during the process of the door 2 rotating outward to open the box body 4, the first sliding door mechanism 1 drives the door panel 3 to slide away from the hinge 5, thereby preventing the door panel 3 from interfering with obstacles on the outside. During the process of the door 2 rotating to close the box body 4, the first sliding door mechanism 1 drives the door panel 3 to slide closer to the hinge 5, thereby preventing the closed door panel 3 from interfering with obstacles.

[0074] In this embodiment, when a door panel 3 is installed on the cabinet door 2 and the refrigeration equipment is embedded in a recessed space or between two cabinets, the door panel 3 can be installed flush with the cabinets on the side wall or sides of the recess to reduce the gap between the refrigeration equipment and the adjacent wall or cabinet, making it more aesthetically pleasing.

[0075] In some embodiments, such as Figure 5 and Figure 6 As shown, the door assembly and the cabinet 4 are arranged within the installation space formed between the first cabinet 6 and the second cabinet 7. An opening is provided on the outer side of the installation space, allowing the door assembly and cabinet 4 to be integrally embedded into the cabinet. During the process of the cabinet door 2 passing through the opening to control the opening or closing of the storage space, the first sliding door mechanism 1 is configured to drive the door panel 3 to move a predetermined distance away from or towards the hinge 5 on the cabinet door 2, so that the door panel 3 avoids the side walls of the first cabinet 6 and the second cabinet 7.

[0076] During the opening or closing of the storage space controlled by the opening through the door 2, the first sliding door mechanism 1 is configured to drive the door panel 3 to move a preset distance away from or towards the hinge 5 on the door 2. In order to avoid interference between the door panel 3 and the side walls of the first cabinet 6 and the second cabinet 7, and to ensure that the door panel 3 can be smoothly opened or closed without colliding or getting stuck with the side walls of the cabinets, the preset distance movement is necessary.

[0077] For example, such as Figure 5 and Figure 6 As shown, during the opening of the cabinet door 2, the first sliding door mechanism 1 drives the door panel 3 to move a preset distance away from the hinge 5 along the cabinet door 2. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 7, allowing the cabinet door 2 to be fully opened, making it convenient for users to store and retrieve items.

[0078] Similarly, during the closing process of the cabinet door 2, the first sliding door mechanism 1 drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 6, allowing the cabinet door 2 to be completely closed, maintaining overall aesthetics and airtightness.

[0079] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand 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 covered within the scope of the claims of the present invention.
