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

[0059] The following will be combined with Figures 1 to 6 Describe the active sliding door mechanism, door body assembly and refrigeration equipment of this application. The active sliding door mechanism and door body assembly in this application can be applied to the cabinet doors or chamber doors of household appliances, such as the chamber door of a refrigerator. However, it should be understood that the door panel mechanism and door body assembly of this application can also be applied to dishwashers, washing machines or any other suitable equipment. The refrigeration equipment in this application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment of this application can also be applied as a freezer or any other suitable equipment.

[0060] In one embodiment of this application, as Figure 1 , Figure 2 and Figure 5As 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 first slider 715 and a traction mechanism, the first slider 715 is slidably arranged on the first guide rail 710; the first slider 715 is connected to the box body 1 through the traction mechanism; a second slider 709, which is slidably arranged on the second guide rail 705, and the second slider 709 is used to be connected to the door panel 21; a transmission member, the two ends of which are respectively in transmission connection with the first slider 715 and the second slider 709; when 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 transmission member.

[0061] The first base of this embodiment can be arranged on the box door 2. The two ends of the transmission member are respectively in transmission connection with the first slider 715 and the second slider 709, so that the first slider 715 can drive the second slider 709 to move synchronously, and then drive the door panel 21 to slide relative to the box door 2.

[0062] By reasonably setting the transmission direction of the transmission 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.

[0063] Specifically, during the process of the box door 2 rotating outward to open relative to the box body 1, the box body 1 drives the first slider 715 to slide in 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 transmission member, so as to avoid interference between the door panel 21 and the outer obstacles. During the process of the box door 2 rotating to close to one side of the box body 1, the box body 1 drives the first slider 715 to slide in the direction 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 transmission member, so as to avoid interference between the door panel 21 and the obstacles after closing.

[0064] 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 slidably provided on the first guide rail 710 and the second guide rail 705 respectively. The first slider 715 and the second slider 709 can slide synchronously along the respective guide rails under the drive of the transmission 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 the 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 transmission 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.

[0065] 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.

[0066] 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 sliders, reduce wear and noise during the sliding process, and ensure the smoothness of the sliding.

[0067] 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 choosing, factors such as usage conditions, cost-effectiveness, and maintenance convenience should be comprehensively considered.

[0068] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the transmission member includes: a first rack 706, a second rack 712, and a gear 716. Among them, the first rack 706 is provided on the first slider 715, and the second rack 712 is provided on the second slider 709. The gear 716 is rotatably provided on the first base and meshes with the first rack 706 and the second rack 712.

[0069] In this embodiment, when the first slider 715 slides along the first guide rail 710, the first rack 706 slides with the first slider 715. The first rack 706 meshes with the gear 716. When the first rack 706 slides, it drives the gear 716 to rotate. The second rack 712 and the first rack 706 are respectively meshed on both sides of the gear 716. When the gear 716 rotates, it can drive the second rack 712 to slide in the opposite direction relative to the first rack 706, thereby driving the second slider 709 to slide in the opposite direction relative to the first slider 715. The structure is simple, convenient and practical.

[0070] In one embodiment of the present application, as Figure 1 and Figure 2 shown, the transmission member further includes: a pin shaft 717. The pin shaft 717 is disposed on the first base, and the gear 716 is rotatably disposed on the pin shaft 717.

[0071] In this embodiment, the pin shaft 717 is disposed on the first base so as to dispose the gear 716. The gear 716 is rotatably disposed on the pin shaft 717 and can rotate around the pin shaft 717 so as to transmit power between the first rack 706 and the second rack 712, causing the first rack 706 and the second rack 712 to slide in opposite directions, and enabling the first slider 715 and the second slider 709 to slide in opposite directions.

[0072] Specifically, as Figure 1 and Figure 2 shown, the first rack 706 and the second rack 712 are spaced apart, and at least part of the first rack 706 and the second rack 712 are oppositely disposed. The gear 716 is disposed between the first rack 706 and the second rack 712.

[0073] In this embodiment, by spacing the first rack 706 and the second rack 712 apart and making at least part of the first rack 706 and the second rack 712 oppositely disposed, there is enough space between the first rack 706 and the second rack 712 to dispose the gear 716. The opposite parts of the first rack 706 and the second rack 712 can simultaneously mesh with both sides of the gear 716. When one of the racks slides driven by the corresponding slider, this rack can drive the gear 716 to rotate, and the gear 716 drives the other rack to slide in the opposite direction, and drives the other rack and the other slider to slide in the opposite direction.

[0074] Further, in some embodiments, limiting portions are provided at both ends of the first rack 706 to limit the moving range of the gear 716.

[0075] In this embodiment, limit portions are provided at both ends of the first rack 706 to block the gear 716, so as to prevent the gear 716 from slipping out of both ends of the first rack 706 when the first rack 706 slides relative to the gear 716, resulting in the separation of the gear 716 and the first rack 706 from each other.

[0076] Similarly, limit portions are provided at both ends of the second rack 712 to limit the movement range of the gear 716.

[0077] In this embodiment, limit portions are provided at both ends of the second rack 712 to block the gear 716, so as to prevent the gear 716 from slipping out of both ends of the second rack 712 when the second rack 712 slides relative to the gear 716, resulting in the separation of the gear 716 and the second rack 712 from each other.

[0078] Optionally, in some embodiments of the present application, as Figure 3 shown, the active sliding door mechanism 7 further includes: a first rolling body and a second rolling body. The first slider 715 is sleeved on the first guide rail 710, and the first slider 715 is slidably disposed on the first guide rail 710 through the first rolling body; the second slider 709 is sleeved on the second guide rail 705, and the second slider 709 is slidably disposed on the second guide rail 705 through the second rolling body.

[0079] In this embodiment, by providing the first rolling body between the first slider 715 and the first guide rail 710, the first rolling body can slide along the first guide rail 710 as the first slider 715 slides, so as to remain between the first slider 715 and the first guide rail 710. The first rolling body can convert at least part of the friction between the first slider 715 and the first guide rail 710 into rolling friction, making the sliding of the first slider 715 smoother; similarly, the second rolling body is slidably disposed between the second slider 709 and the second guide rail 705, and can convert at least part of the friction between the second slider 709 and the second guide rail 705 into rolling friction, making the sliding of the second slider 709 smoother, thereby making the relative sliding between the box door 2 and the door panel 21 smoother.

[0080] In an embodiment of the present application, as Figure 3 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 bodies include a first ball 7141 and a second ball 7071. The first ball 7141 is rotatably disposed in the first rolling gap, and the second ball 7071 is rotatably disposed in the second rolling gap.

[0081] In this embodiment, by forming a first rolling gap between the first slider 715 and the first guide rail 710 and a second rolling gap between the second slider 709 and the second guide rail 705 respectively, direct contact between the first slider 715 and the first guide rail 710 and between the second slider 709 and the second guide rail 705 can be avoided. The first rolling balls 7141 and the second rolling balls 7071 are respectively arranged in the first rolling gap and the second rolling gap in a rollable manner, so that the first slider 715 can slide along the first guide rail 710 through the rolling of the first rolling balls 7141, and the second slider 709 can slide along the second guide rail 705 through the rolling of the second rolling balls 7071, with small friction and smoother sliding.

[0082] In an embodiment of the present application, as Figure 3 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 first rolling elements include multiple groups of first rolling balls 7141, the second rolling elements include multiple groups of second rolling balls 7071, and each group of first rolling balls 7141 is respectively arranged in each row of first rolling gaps, and each group of second rolling balls 7071 is respectively arranged in each row of second rolling gaps.

[0083] In this embodiment, by setting multiple rows of first rolling gaps and arranging a group of first rolling balls 7141 in each row of first rolling gaps, multiple rolling support points can be formed between the first slider 715 and the first guide rail 710 by the multiple groups of first rolling balls 7141, 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 group of second rolling balls 7071 in each row of second rolling gaps, multiple rolling support points can also be formed between the second slider 709 and the second guide rail 705 by the multiple groups of second rolling balls 7071, making the sliding of the second slider 709 relative to the first guide rail 710 more stable and smooth.

[0084] Optionally, the multiple first rolling gaps in each row can be arranged at intervals along the extending direction of the first guide rail 710, and the multiple second rolling gaps in each row can be arranged at intervals along the extending direction of the second guide rail 705.

[0085] Furthermore, as Figure 3 shown, the first guide rail 710 is provided with multiple first concave surfaces arranged in sequence along its circumferential direction, the first slider 715 is formed with a first groove, and the side walls of the first groove and the multiple first concave surfaces form multiple rows of first rolling gaps. The second guide rail 705 is provided with multiple second concave surfaces arranged in sequence along its circumferential direction, the second slider 709 is formed with a second groove, and the side walls of the second groove and the multiple second concave surfaces form multiple rows of second rolling gaps.

[0086] 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. Meanwhile, 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 on 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.

[0087] Optionally, the first concave surface is an arc surface that fits the first ball 7141, and an arc surface that fits the first ball 7141 is also formed at the position corresponding to the first concave surface on the side wall of the first groove, so that the first concave surface and the first groove better fit the first ball 7141, with a larger force-bearing area and more stable and reliable rolling. Similarly, the second concave surface is an arc surface that fits the second ball 7071, and an arc surface that fits the second ball 7071 is also formed at the position corresponding to the second concave surface on the side wall of the second groove, so that the second concave surface and the second groove better fit the second ball 7071, with a larger force-bearing area and more stable and reliable rolling.

[0088] In one embodiment of the present application, as Figure 3 shown, the first rolling element further includes: a first support frame 714, and the second rolling element further includes: a second support frame 707. The first support frame 714 is disposed between the first slider 715 and the first guide rail 710. The first support frame 714 is provided with a first limiting notch at a position corresponding to the first rolling gap, and the first ball 7141 is disposed in the first limiting notch. The second support frame 707 is disposed between the second slider 709 and the second guide rail 705. The second support frame 707 is provided with a second limiting notch at a position corresponding to the second rolling gap, and the second ball 7071 is disposed in the second limiting notch.

[0089] In this embodiment, by providing a first support frame 714 between the first slider 715 and the first guide rail 710, a first limiting notch is formed on the first support frame 714 to provide a first ball 7141, so as to limit the first ball 7141 and prevent the first ball 7141 from rolling and shifting in the first rolling gap, making the sliding of the first slider 715 more stable and reliable. Similarly, by providing a second support frame 707 between the second slider 709 and the second guide rail 705 to limit the second ball 7071, the sliding of the second slider 709 is made more stable and reliable.

[0090] In an embodiment of another aspect of the present application, as Figure 1 , Figure 4 and Figure 5 shown, a door assembly is provided, including: 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 adapted to open or close the storage space of the box body 1. The door panel 21 is slidably provided on the outer side of the box door 2; the active sliding door mechanism 7 is provided on the box door 2, and the first slider 715 is drivingly connected to the box body 1 through a traction mechanism, and the second slider 709 is connected to the door panel 21. During the opening or closing process of the box door 2, the first slider 715 and the second slider 709 move in opposite directions to drive the door panel 21 to move relative to the width direction of the box door 2.

[0091] It can be understood that the width direction of the box door 2 is parallel to the plane where the box door 2 is located and perpendicular to the rotation axis of the box door 2, so that the door panel 21 can move away from or close to the rotation axis of the box door 2 (as Figure 4 shown by the double-headed arrow in

[0092] ). It should be noted that for the parallel and perpendicular relationships in the present application, the installation errors between various components need to be considered, and an error of plus or minus 10° should be understood as the scope protected by the patent. Specifically, during the process of the box door 2 rotating and opening outward from the box body 1 (as Figure 4 shown by the arc arrow in

[0093] ), the first slider 715 slides in the direction close to the first hinge 4 under the drive of the box body 1. The first slider 715 drives the second slider 709 to slide in the direction away from the first hinge 4 through a transmission member, thereby driving the door panel 21 to slide in the direction away from the first hinge 4, and further preventing the door panel 21 from interfering with the outer obstacles. Similarly, during the process of the box door 2 rotating and closing toward one side of the box body 1, the active sliding door mechanism 7 drives the door panel 21 to slide in the direction close to the first hinge 4, thereby preventing the door panel 21 from interfering with the obstacles after closing.According to the door body assembly of the embodiment of the present application, an active sliding door mechanism 7 is provided on the box door 2, and the active sliding door mechanism 7 is respectively connected to the box body 1 and the door panel 21, so as 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.

[0094] 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, and its specific implementation manner can refer to the above embodiment, and the present application will not be elaborated herein.

[0095] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the door body assembly further includes a traction mechanism, and 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, the second rotating shaft fixing seat 701 is used for connecting 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.

[0096] 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, the first slider 715 is tractioned through the transmission connection of the traction rod 702, the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, so that the first slider 715 slides on the 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.

[0097] In an embodiment of the present application, as Figure 5 and Figure 6 shown, the door body assembly further includes: a driven sliding door mechanism 8, and 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, the third slider 813 is slidably arranged on the third guide rail, and the third slider 813 is connected to the door panel 21.

[0098] In this embodiment, by providing a driven sliding door mechanism 8 on the cabinet door 2, the driven sliding door mechanism 8 has a second base 817, a third guide rail is provided on the second base 817, and a third slider 813 that can slide along the third guide rail, and 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 cabinet door 2, playing a role in supporting and assisting the sliding of the door panel 21, making the sliding of the door panel 21 relative to the cabinet 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 of the door panel 21 during the sliding process and making the sliding more stable.

[0099] 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 arranged on the cabinet door 2 with different axes from the active sliding door mechanism 7.

[0100] 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 movement direction or maintaining the relative positional relationship between components is required.

[0101] The driven sliding door mechanism 8 and the active sliding door mechanism 7 are arranged with different axes, which means 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.

[0102] In an embodiment of another aspect of the present application, as Figure 4 and Figure 5 shown, a refrigeration device is provided, including: a cabinet 1 and a door body assembly as provided in any of the above - mentioned embodiments. Among them, the cabinet 1 forms a storage space, and the cabinet door 2 is rotatably connected to the cabinet 1 and is adapted to open or close the storage space.

[0103] In this embodiment, the door body assembly includes: a cabinet door 2, a door panel 21, and a sliding door device. The sliding door device includes at least two active sliding door mechanisms 7, and the active sliding door mechanisms 7 are arranged on the cabinet door 2 and are 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.

[0104] By providing 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 between two cabinets, the door panel 21 can be set flush with the side wall of the groove or the cabinets on both sides to reduce the gap between the refrigeration device and the adjacent wall or cabinet, making it more beautiful.

[0105] Meanwhile, 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 away as possible from obstacles such as the wall of the side door of the cabinet body 1 or the cabinet, so as to prevent these obstacles from blocking the door panel 21 and affecting the rotation of the cabinet door 2, resulting in the cabinet door 2 being unable to be opened or closed normally.

[0106] The combination of the cabinet 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 usability. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the slider and guide rail in the active sliding door mechanism 7 enables the door panel 21 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0107] 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, and its specific implementation manners can refer to the above embodiments, which will not be elaborated in this application.

[0108] It can be understood that there can be multiple storage spaces.

[0109] It can be understood that the multiple storage spaces can be arranged arbitrarily, such as arranged vertically or horizontally. The 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.

[0110] As Figure 4 shown, based on an application scenario of the above embodiments: The refrigeration equipment can be installed in a trough-shaped structure in the middle of a cabinet. A door panel 21 is arranged on the outer side of the cabinet door 2 of the cabinet body 1 of the refrigeration equipment, and the material and color of the door panel 21 can be designed to be similar to or the same as the material color of the outer wall of the cabinet. When the cabinet 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.

[0111] When the cabinet 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 prevent the door panel 21 from interfering with the cabinet wall on the side close to the first hinge 4, resulting in the cabinet door 2 being unable to be opened to a larger angle. When the cabinet door 2 rotates to close, the active sliding door mechanism 7 drives the door panel 21 to slide towards the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side far from the first hinge 4, resulting in the cabinet door 2 being unable to be completely closed and affecting the refrigeration preservation effect in the storage space. And when the cabinet door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet again.

[0112] In one embodiment of the present application, the box body 1 has a first storage space and a second storage space. There are two door body assemblies, namely 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.

[0113] In this embodiment, by providing the first storage space and the second storage space on the box body 1, the items to be stored are separately stored according to requirements. The first storage space and the second storage space are respectively provided with the first door body assembly and the second door body assembly, so that when the box doors 2 of the first door body assembly and the second door body assembly are rotated to open and close, the corresponding door panels 21 can slide relative to the box door 2 to avoid obstacles.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
