[0057] In one embodiment of the present application, Figure 1 , Figure 3 and Figure 4 As shown, the sliding door device is applied to refrigeration equipment, and is used to be arranged on a door 2 with a door panel 21 on the outside. The door 2 is rotatably connected to the box body 1, and the door 2 is suitable for opening or closing the storage space of the box body 1. The sliding door device includes: an active sliding door mechanism 7, including: a first base, a traction mechanism, a first slider 715, a second slider 709 and a connecting member; the first base is used to be arranged on the door 2, and 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; the first slider 715 is slidably arranged on the first guide rail 710, and the first slider 715 is transmission-connected to the box body 1 through the traction mechanism; the second slider 709 is slidably arranged on the second guide rail 705; The two ends are respectively connected to the first slider 715 and the second slider 709; the driven sliding door mechanism 8 includes: a second base 817 and a third slider 813; the second base 817 is used to be set on the box door 2, and a third guide rail is formed on the second base 817, and the third slider 813 is slidably set on the third guide rail; the connecting rod 10 is connected to the second slider 709 and the third slider 813, so that when the first slider 715 moves along the first guide rail 710 driven by the traction mechanism, the first slider 715 drives the second slider 709 to move in the opposite direction on the second guide rail 705 through the connecting piece, and cooperates with the connecting rod 10 to drive the third slider 813 to move in the opposite direction on the third guide rail.

[0058] It is understandable that if Figure 1 , Figure 3 and Figure 4 As shown, the active sliding door mechanism 7 of this embodiment can be arranged on the box door 2, the first slider 715 is connected to the box body 1 through a traction mechanism, and the second slider 709 is slidably connected to the door panel 21 arranged on the outside of the box door 2, so that when the box door 2 rotates, the two sliders 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 when the box door 2 is turned on and off.

[0059] Specifically, the first base of this embodiment can be set on the box door 2. The connecting member can be a connecting member such as a traction rope, a transmission belt, etc., and the two ends of the connecting member are respectively connected to the first slider 715 and the second slider 709, so that the first slider 715 can drive the second slider 709 to move synchronously, thereby driving the door panel 21 to slide relative to the box door 2.

[0060] By properly setting the extending direction of the connecting member, the first slider 715 and the second slider 709 move in opposite directions, so as to drive the door panel 21 to avoid obstacles.

[0061] Specifically, when the door 2 is rotated to the outside of the box body 1 to open, the box body 1 drives the first slider 715 to slide in the direction close to the first hinge 4 through the traction mechanism, and at the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., away from the first hinge 4) through the connecting member, thereby avoiding interference between the door panel 21 and obstacles on the outside. When the door 2 is rotated to one side of the box body 1 to close, the box body 1 drives the first slider 715 to slide in the direction away from the first hinge 4 through the traction mechanism, and at the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., close to the first hinge 4) through the connecting member, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0062] At the same time, the third slider 813 of the driven sliding door mechanism 8 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 with the door panel 21, and play a supporting and auxiliary role in the sliding of the door panel 21, and cooperate with the active sliding door mechanism 7 to limit the movement direction of the door panel 21 to prevent the door panel 21 from shaking during the movement. In addition, the third slider 813 and the second slider 709 are connected by a connecting rod 10 to increase the synchronization of the sliding of the third slider 813 and the second slider 709, so that the sliding of the door panel 21 is more stable.

[0063] According to the sliding door device of the embodiment of the present application, the box door 2 is rotatably connected to the box body 1, the door panel 21 is slidably arranged on the outer side of the box door 2, and an active sliding door mechanism 7 is arranged on the box door 2. The active sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21, so that during the process of the box door 2 rotating relative to the box body 1 to open or close, the door panel 21 is driven to slide in the width direction of the box door 2, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening process of the box door 2, to meet the usage requirements of users in different scenarios. At the same time, by arranging a driven sliding door mechanism 8 to support and assist the sliding of the door panel 21, the sliding of the door panel 21 is more stable and smooth, and the use effect is better. In addition, the third slider 813 of the driven sliding door mechanism 8 and the second slider 709 of the active sliding door mechanism 7 are connected by a connecting rod 10, so that the sliding synchronization of the connected sliders is better, and thus the sliding of the door panel 21 is more stable.

[0064] It should be noted that in practical applications, the design 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.

[0065] 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 sliding.

[0066] 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.

[0067] Optionally, in some embodiments of the present application, such as Figure 3 and Figure 4 shown, the active sliding door mechanism 7 further includes: a first ball support member and a second ball support member. The first ball support member is slidably internally connected to the first guide rail 710, and the first slider 715 is slidably internally connected to the first ball support member. The second ball support member is slidably internally connected to the corresponding second guide rail 705, and the second slider 709 is slidably internally connected to the second ball support member.

[0068] In this embodiment, by providing a first ball support member between the first slider 715 and the first guide rail 710, the first ball support member can slide along the first guide rail 710 as the first slider 715 slides, so as to maintain between the first slider 715 and the first guide rail 710. The first ball support member 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 ball support member is slidably provided 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.

[0069] Specifically, in an embodiment of the present application, as Figure 3 and Figure 4 shown, the first ball support member includes: a first ball (not shown in the figure) and a first support frame 714; the second ball support member includes: a second ball (not shown in the figure) and a second support frame 707. A first limiting notch is formed on the first support frame 714, the first ball is rotatably disposed in the corresponding first limiting notch, one side of the first ball abuts against the corresponding first guide rail 710, and the other side of the first ball passes through the corresponding first limiting notch and abuts against the first slider 715. A second limiting notch is formed on the second support frame 707, the second ball is rotatably disposed in the corresponding second limiting notch, one side of the second ball abuts against the corresponding second guide rail 705, and the other side of the second ball passes through the corresponding second limiting notch and abuts against the second slider 709.

[0070] In this embodiment, a first support frame 714 is provided 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 to limit the first ball and prevent the first ball from rolling and shifting, making the sliding of the first slider 715 more stable and reliable. Both sides of the first ball abut against the first guide rail 710 and the first slider 715 respectively. When the first slider 715 rolls relative to the first guide rail 710, the first ball can roll to convert at least part of the friction received by the first slider 715 into rolling friction, making the sliding of the first slider 715 smoother. Similarly, a second support frame 707 is provided between the second slider 709 and the second guide rail 705, and a second limiting notch is formed on the second support frame 707 to set the second ball to limit the second ball and prevent the second ball from rolling and shifting, making the sliding of the second slider 709 more stable and reliable. Both sides of the second ball abut against the second guide rail 705 and the second slider 709 respectively. When the second slider 709 rolls relative to the second guide rail 705, the second ball can roll to convert at least part of the friction received by the second slider 709 into rolling friction, making the sliding of the second slider 709 smoother.

[0071] Optionally, a plurality of first balls and second balls are provided.

[0072] Optionally, in an embodiment of the present application, as Figure 3 and Figure 4 shown, the first support frame 714 is provided with first limiting notches on both opposite sides corresponding to the first guide rail 710. There are two groups of first balls, and the two groups of first balls are respectively arranged in the first limiting notches on both sides to rollingly abut against both sides of the corresponding first slider 715. The second support frame 707 is provided with second limiting notches on both opposite sides corresponding to the second guide rail 705. There are two groups of second balls, and the two groups of second balls are respectively arranged in the second limiting notches on both sides to rollingly abut against both sides of the corresponding second slider 709.

[0073] In this embodiment, by arranging the first limiting notches on both sides of the first slider 715, the two groups of first balls are respectively rotatably arranged on both sides of the first slider 715 and respectively abut against the first slider 715 and the first guide rail 710. While converting at least part of the friction received by the first slider 715 into rolling friction, the forces on both sides of the first slider 715 can be made more balanced, making the first slider 715 slide more stably and smoothly relative to the first guide rail 710. Similarly, the two groups of second balls are also respectively rotatably arranged on both sides of the second slider 709. While converting at least part of the friction received by the second slider 709 into rolling friction, the forces on both sides of the second slider 709 can be made more balanced, making the second slider 709 slide more stably and smoothly relative to the second guide rail 705.

[0074] Specifically, in an embodiment of the present application, as Figure 3 and Figure 4 shown, the driven sliding door mechanism 8 further includes a third ball support member. The third ball support member is slidably internally connected to the third guide rail, and the third slider 813 is slidably internally connected to the third ball support member.

[0075] In this embodiment, by arranging the third ball support member between the third slider 813 and the third guide rail, the third ball support member can slide along the third guide rail as the third slider 813 slides to remain between the third slider 813 and the third guide rail. The third ball support member can convert at least part of the friction between the third slider 813 and the third guide rail into rolling friction, making the sliding of the third slider 813 smoother.

[0076] Specifically, in an embodiment of the present application, as Figure 3 and Figure 4As shown, the third ball support member includes: a third ball (not shown in the figure) and a third support frame 814. A third limit notch is formed on the third support frame 814, and the third ball is rotatably disposed in the corresponding third limit notch. One side of the third ball abuts against the corresponding third guide rail, and the other side of the third ball passes through the third limit notch and abuts against the third slider 813.

[0077] In this embodiment, a third support frame 814 is disposed between the third slider 813 and the third guide rail. A third limit notch is formed on the third support frame 814 to dispose the third ball, so as to limit the third ball and prevent the third ball from rolling and shifting, making the sliding of the third slider 813 more stable and reliable. Both sides of the third ball abut against the third guide rail and the third slider 813 respectively. When the third slider 813 rolls relative to the third guide rail, the third ball can roll to convert at least part of the friction received by the third slider 813 into rolling friction, making the sliding of the third slider 813 smoother.

[0078] Optionally, in an embodiment of the present application, as Figure 3 and Figure 4 shown, third limit notches are provided on both sides of the third support frame 814 corresponding to the opposite sides of the third guide rail. There are two sets of third balls, and the two sets of third balls are respectively disposed in the third limit notches on both sides to rotatably abut against both sides of the corresponding third slider 813.

[0079] In this embodiment, by disposing the third limit notches on both sides of the third slider 813, the two sets of third balls are respectively rotatably disposed on both sides of the third slider 813 and respectively abut against the third slider 813 and the third guide rail. While converting at least part of the friction received by the third slider 813 into rolling friction, the forces on both sides of the third slider 813 can be made more balanced, making the third slider 813 slide more stably and smoothly relative to the third guide rail.

[0080] In an embodiment of the present application, as Figure 3 and Figure 4 shown, the connecting member includes: a first connecting member 706 and a second connecting member 712.

[0081] 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 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.

[0082] In one embodiment of the present application, as Figure 3 and Figure 4 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 forms 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 forms 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.

[0083] 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 respectively form a first limiting groove and a second limiting groove that are butted against the first guide rail 710 and the second guide rail 705, respectively limiting and guiding the positions of the first connecting member 706 and the second connecting member 712, so that the sliding of the first connecting member 706 and the second connecting member 712 is smoother and more stable.

[0084] In another embodiment of the present application, as Figure 1 、 Figure 3 and Figure 4As shown in the figure, a door body assembly is provided, including: a box door 2, a door panel 21, and a sliding door device 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 disposed on the outer side of the box door 2; the sliding door device is disposed 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 and the third slider 813 are both connected to the door panel 21. During the opening or closing process of the box door 2, the first slider 715 moves in the opposite direction to the second slider 709 and the third slider 813 to drive the door panel 21 to move in the width direction of the box door 2.

[0085] 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 shown by the double-headed arrow in Figure 2 the figure). It should be noted that for the parallel and perpendicular relationships in this 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.

[0086] In this embodiment, during the process of the box door 2 rotating and opening outward from the box body 1 (as shown by the arc arrow in Figure 2 the figure), the first slider 715 slides in the direction close to the first hinge 4 under the drive of the box body 1 and the traction mechanism. The first slider 715 drives the second slider 709 to slide in the direction away from the first hinge 4 through a connecting member, thereby driving the door panel 21 to slide in the direction away from the first hinge 4, and further avoiding interference between the door panel 21 and the external obstacles. Similarly, during the process of the box door 2 rotating and closing to 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 avoiding interference between the door panel 21 and the obstacles after closing.

[0087] At the same time, during the sliding process of the door panel 21, the third slider 813 of the driven sliding door mechanism 8 can slide along with the door panel 21 to play a role in supporting and assisting the sliding of the door panel 21. In addition, the third slider 813 of the driven sliding door mechanism 8 and the second slider 709 of the active sliding door mechanism 7 are connected by a connecting rod 10, and the sliding synchronization of the connected sliders is better, so that the sliding of the door panel 21 is more stable.

[0088] According to the door body assembly of the embodiment of the present application, a sliding door device is provided on the box door 2. The sliding door device includes an active sliding door mechanism 7. The active sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21, so as to drive the door panel 21 to slide in the width direction of the box door 2 during the process of the box door 2 rotating relative to the box body 1 to open or close, 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, by providing a driven sliding door mechanism 8 to support and assist the sliding of the door panel 21, the sliding of the door panel 21 is more stable and smooth, and the use effect is better. In addition, the third slider 813 of the driven sliding door mechanism 8 and the second slider 709 of the active sliding door mechanism 7 are connected by a first connecting rod 10, so that the sliding synchronization of the connected sliders is better, and thus the sliding of the door panel 21 is more stable.

[0089] It can be understood that if the sliding door device 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 be elaborated herein.

[0090] In an embodiment of the present application, as Figure 3 and Figure 4 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, 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.

[0091] 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 base, and drives the second slider 709 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0092] In an embodiment of the present application, as Figure 3 and Figure 4 shown, at least one of the second slider 709, the third slider 813 and the connecting rod 10 is provided with a slot for the door panel 21 to be hung.

[0093] In this embodiment, by providing a slot for hanging the door panel 21 on at least one of the second slider 709, the third slider 813, and the connecting rod 10, it is convenient for the user to hang the door panel 21 on the sliding door device, so that the door panel 21 can slide relative to the cabinet 1 under the drive of the sliding door device.

[0094] In an embodiment of another aspect of the present application, as Figure 1 and Figure 2 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 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.

[0095] In this embodiment, the door assembly includes: a cabinet door 2, a door panel 21, and a sliding door device. The sliding door device includes a main sliding door mechanism 7 and a driven sliding door mechanism 8. The main sliding door mechanism 7 is arranged on the cabinet door 2 and is configured to drive the door panel 21 to move in the width direction of the cabinet door 2 during the opening or closing of the cabinet door 2. The driven sliding door mechanism 8 can assist the sliding of the door panel 21.

[0096] The third slider 813 of the driven sliding door mechanism 8 and the second slider 709 of the main sliding door mechanism 7 are connected by a connecting rod 10, so that the sliding synchronization of the connected sliders is better, and thus the sliding of the door panel 21 is more stable.

[0097] By providing the door panel 21 on the cabinet door 2, when the refrigeration device is built-in and arranged in a groove-shaped space, or 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.

[0098] At the same time, when the cabinet door 2 rotates, the main 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 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 opened or closed normally.

[0099] The combination of the cabinet door 2 and the door panel 21 enables the refrigeration device 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 sliders and guide rails in the main sliding door mechanism 7, and the connection of the third slider 813 of the driven sliding door mechanism 8 and the second slider 709 of the main sliding door mechanism 7 by the first connecting rod 10 enable the door panel 21 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0100] It can be understood that the door body assembly has the beneficial effects of the above embodiments, and the refrigeration device 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.

[0101] It can be understood that there can be multiple storage spaces.

[0102] 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 requirements. For example, some storage spaces are set as refrigerating chambers, and another part of the storage spaces are set as freezing chambers.

[0103] As Figure 2 shown, based on an application scenario of the above embodiment is as follows: The refrigeration device can be installed in a groove-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 box body 1 of the refrigeration device, 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 groove-shaped structure, and is as close as possible to the opening of the groove-shaped structure, so that the door panel 21 and the outer wall of the cabinet can maintain visual consistency and have a small gap, which is more beautiful.

[0104] When the cabinet door 2 rotates outward to open, the active sliding door mechanism 7 drives the door panel 21 to slide in a direction away from the first hinge 4, so as to avoid interference between the door panel 21 and the cabinet wall on the side close to the first hinge 4, resulting in the cabinet door 2 being unable to open 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 in a direction close to the first hinge 4, so as to avoid interference between the door panel 21 and the cabinet wall on the side away 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 body again.

[0105] In an 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 a first door body assembly and a second door body assembly. The cabinet 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 cabinet door 2 of the second door body assembly is rotatably connected to the box body 1 to open or close the second storage space.

[0106] In this embodiment, by providing a first storage space and a second storage space on the box body 1, the items to be stored are stored separately according to requirements. The first storage space and the second storage space are respectively provided with a first door body assembly and a second door body assembly, so that when the cabinet 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 cabinet doors 2 to avoid obstacles.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than limiting 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.
