Description

[Technical Field]

[0001] The present application relates to the field of smart self-service devices, and more particularly to host equipment and self-service devices. [Background technology]

[0002] A self-service device is a smart device that completes user requests through interface devices such as a touch panel or keyboard, providing consumers with convenient services such as reservation reservations, cash withdrawals, paperwork, shopping, and payments. The front of current self-service devices typically features a coin insertion device, a scanning electronic payment device, and input / output devices such as a keyboard and panel. These devices penetrate the cabinet panel on the front of the self-service device, with a portion exposed on the cabinet surface for user operation and another portion extending into the cabinet and connected to the host machine of the self-service device.

[0003] However, to prevent these devices from being disassembled by anyone other than maintenance personnel, the mounting structures for these devices are all provided inside the self-service device. Therefore, when installing these devices, one person must hold the payment device or interactive device in front of the cabinet panel while another person must install the device on the back of the cabinet panel. This requires multiple workers to install, disassemble, and maintain the self-service device, resulting in low work efficiency. Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, the present application provides a self-service device that is easy to install and disassemble, and that can reduce the amount of manpower required for maintenance of the self-service device. [Means for solving the problem]

[0005] An embodiment of the present application provides a host device. The host device is mounted on a cabinet panel, the cabinet panel having a front surface, a back surface, and a mounting hole penetrating the front and back surfaces, and the host device includes a host and a back clip. The host has a first mounting surface that is in close contact with the front surface, and a support structure is provided on the first mounting surface, and the support structure abuts against the inner peripheral wall of the mounting hole. The back clip is in close contact with the back surface and is detachably connected to the host, and the support structure is housed in the back clip.

[0006] By providing the support structure and back clip, when a maintenance worker installs a host device on a cabinet panel, the host's support structure is first abutted against the inner wall of the mounting hole to hook the host to the front of the cabinet panel. At this time, a portion of the host structure is exposed through the mounting hole. Next, the maintenance worker goes around to the back of the cabinet panel and connects the back clip to the portion of the host exposed through the mounting hole. This allows the host and back clip to cooperate to sandwich the front and back of the cabinet panel, securing the host device to the cabinet panel. By using the support structure to hook the host to the mounting hole, a maintenance worker does not need to have another worker support the host device in front of the cabinet panel when installing the host on the back of the cabinet panel. As a result, all installation work can be completed by a single maintenance worker, improving the efficiency of host device installation, disassembly, maintenance, and other tasks.

[0007] In at least one embodiment, the host includes a body portion and a mounting portion, the mounting portion being located on a side of the body portion facing a back clip, the first mounting surface being on the body portion, the mounting portion at least partially extending into a mounting hole, and being detachably connected to the back clip.

[0008] By providing the main body and the mounting portion, the first mounting surface of the main body fits tightly against the front surface of the cabinet panel, and the mounting portion penetrates deep into the mounting hole and extends to the rear surface of the cabinet panel, facilitating the work of connecting the back clip to the mounting portion from the rear side of the cabinet panel.

[0009] In at least one embodiment, the support structure includes a fixing portion and a receiving portion, the fixing portion being connected to the first mounting surface, the receiving portion being connected to the fixing portion and disposed at an angle to the fixing portion, and the receiving portion being adapted to abut against an inner peripheral wall of the mounting hole.

[0010] The design of the receiving part, combined with the first mounting surface, forms a structure that restricts the movement of the host in two directions. When the first mounting surface is in close contact with the front of the cabinet panel, the receiving part abuts against the inner wall of the mounting hole, providing an upward support force from the inner wall to the host, preventing it from falling.

[0011] In at least one embodiment, the support structure further includes a blocking portion connected to an end of the receiving portion remote from the fixed portion, angled relative to the receiving portion, and extending to a rear surface of the cabinet panel, for blocking horizontal displacement of the host.

[0012] The design of the blocking part ensures that when the host is hung on the inner wall of the mounting hole and its center of gravity tries to slide off the first mounting surface, the blocking part abuts against the rear surface of the cabinet panel, preventing the host from easily falling and improving stability when hung. Furthermore, even if the host tilts slightly while the blocking part is abutting against the rear surface of the cabinet panel, the maintenance worker can still adjust the position of the mounting part on the rear side of the cabinet panel, which does not affect the installation of the back clip on the rear surface.

[0013] In at least one embodiment, the support structure and the blocking portion are resilient structures.

[0014] By making the support structure and the blocking portion elastic, when the host is hooked onto the inner peripheral wall of the mounting hole via the support structure and the blocking portion, the host can be partially displaced. This allows the maintenance worker to fine-tune the relative position of the host and the back clip when attaching the back clip to the rear side of the cabinet panel, and improves installation efficiency without being hindered by the support structure and the blocking portion.

[0015] In at least one embodiment, the first mounting surface is provided with a plurality of coupling holes, and the support structure is detachably connected to any of the coupling holes.

[0016] By providing multiple connecting holes, if a maintenance technician finds that the actual mounting hole shape does not match the design, they can remove the support structure and adjust the relative position of the support structure and host to match the position of the actual mounting hole's inner wall. Because there are multiple standard mounting hole specifications for cabinet panels, designing the positions of multiple connecting holes according to different standards makes it easy to adapt the host to mounting holes of different specifications. Furthermore, if the support structure is damaged during production or transportation, it can be replaced independently, reducing material costs.

[0017] In at least one embodiment, the first mounting surface is provided with a first magnetic attraction member, and the cabinet panel is provided with a second magnetic attraction member, or the cabinet panel is made of a magnetic attraction material.

[0018] By adopting a magnetic attraction connection method, the first mounting surface is more firmly connected to the cabinet panel and will not easily fall off.

[0019] In at least one embodiment, the back clip has a second mounting surface that surrounds the mounting hole and is in close contact with the rear surface of the cabinet panel.

[0020] By designing the second mounting surface to have a shape that surrounds the mounting hole, when the host and back clip sandwich the cabinet panel, the entire inner wall of the mounting hole can be sandwiched, improving the connection strength between the host and back clip.

[0021] In at least one embodiment, the second mounting surface is provided with a recessed groove for receiving the support structure.

[0022] By providing the recess, when the back clip is connected to the host, the support structure and the blocking portion are accommodated in the recess, so that the second mounting surface does not get in close contact with the back surface of the cabinet panel, thereby improving the connection strength between the back clip and the host.

[0023] In at least one embodiment, the second mounting surface is symmetrically arranged, and a plurality of the recesses are arranged in the second mounting surface, some of which are used to accommodate a support structure.

[0024] The symmetrical design of the escape groove allows the escape groove to accommodate the support structure when the back clip is attached to the host, whether in normal or reverse installation, which eliminates the need for maintenance workers to align the escape groove with the support structure, thereby saving work time.

[0025] In another aspect, an embodiment of the present application further provides a self-service device including a cabinet and any of the host devices described above. The cabinet is provided with a cabinet panel having a front surface, a rear surface, and mounting holes extending through the front surface and the rear surface. The host device is attached to the mounting holes.

[0026] By installing a host device with a support structure on the cabinet body, when maintaining the self-service device, the host device can be first hooked onto the mounting hole during installation, and the host device will not fall when disassembled. This allows installation and disassembly of the host device to be completed by one person.

[0027] The host device described above employs a cooperative design between the support structure and back clip. When a maintenance technician installs the host device in a cabinet panel, the technician first abuts the host's support structure against the inner wall of the mounting hole, thereby hooking the host to the front of the cabinet panel. At this time, a portion of the host structure is exposed through the mounting hole. The technician then moves to the rear of the cabinet panel and connects the back clip to the portion of the host exposed through the mounting hole. The host and back clip then cooperate to clamp the front and rear of the cabinet panel, securing the host device. By using the support structure to hook the host into the mounting hole, a technician can install the host on the rear of the cabinet panel without needing a second technician to support the host device from the front. As a result, installation, disassembly, maintenance, and other tasks can be completed by one person, significantly improving work efficiency. [Brief explanation of the drawings]

[0029] In order to further clarify the technical means and effects adopted by the present application to achieve the specified objects, the following description will be given with reference to the accompanying drawings and embodiments, however, the described embodiments are only a part of the present application and do not cover all the embodiments.

[0030] All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terms used herein are intended for the purpose of describing specific embodiments only and are not intended to be limiting of this application.

[0031] It should be noted that when a component is described as being "connected" or "provided" on another component, the component may be directly connected to the other component, or an intermediate component may be present. In this application, unless otherwise clearly defined or limited, terms such as "attach," "connect," and "fix" are to be interpreted broadly. For example, they may be fixedly connected, detachably connected, integrally connected, mechanically connected, or electrically connected, or may be directly connected or indirectly connected via an intermediate medium. Furthermore, "connecting" may also mean internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this application depending on the specific circumstances.

[0032] The terms "first," "second," etc. are used only to distinguish different objects and do not indicate or imply relative importance. Nor do they imply a quantity, a particular order, or a primary relationship of the indicated technical features. In describing the embodiments of the present application, unless otherwise clearly and specifically limited, "plurality" means two or more. Descriptions of shapes such as length, thickness, and width in the examples of the present application are merely illustrative and do not absolutely limit the present application. Hereinafter, several examples of the present application will be described in detail with reference to the accompanying drawings. Unless a contradiction arises, the following examples and features in the examples can be combined with each other.

[0033] A self-service device is a smart device that completes user requests through interactive devices such as a touch panel or keyboard, providing consumers with convenient services such as reservation reservations, paperwork, shopping, and payments. Current self-service devices typically have a coin slot, a scanning electronic payment device, and input / output devices such as a keyboard or panel on the front. These devices penetrate the cabinet panel on the front of the self-service device, with a portion exposed on the cabinet surface for user operation and another portion extending into the interior of the cabinet and connected to the host computer of the self-service device.

[0034] However, to prevent these devices from being disassembled by anyone other than maintenance personnel, the mounting structures for these devices are all provided inside the self-service device. Therefore, when installing these devices, one person must support the payment device or interactive device in front of the cabinet panel while another person must install the device on the back of the cabinet panel. This requires multiple workers to install, disassemble, and maintain the self-service device, resulting in low work efficiency.

[0035] 1 and 2, a host device 200 according to an embodiment of the present application is attached to a cabinet panel 1. The cabinet panel 1 has a front surface 101, a rear surface 102, and an attachment hole 11 penetrating the front surface 101 and the rear surface 102. The host device 200 includes a host 2 and a back clip 3.

[0036] 2 and 3, the host 2 has a first mounting surface 211 that is in close contact with the front surface 101. A support structure 23 is provided on the first mounting surface 211. The support structure 23 abuts against the inner peripheral wall 111 of the mounting hole 11. The back clip 3 is in close contact with the rear surface 102 and is detachably connected to the host 2. The support structure 23 is housed within the back clip 3.

[0037] The cabinet panel 1 of a self-service device can be opened and closed like a door to expose the internal structure of the cabinet. These cabinets are usually provided with device structures that can be operated by a user on the cabinet panel 1. Several mounting holes 11 are pre-installed to attach these device structures. Because the cabinet panel 1 is formed from a sheet metal part stamped with a mold, the edges of the mounting holes 11 have a thin structure. The host 2 is a device that allows user operation, and its surface that comes into close contact with the cabinet panel 1 is a first mounting surface 211. A support structure 23 provided on the first mounting surface 211 cooperates with the edge of the mounting hole 11 to enable the host device 200 to be hung on the inner wall 111 of the mounting hole 11.

[0038] The edges of the mounting holes 11 can be bent toward the inside of the cabinet, thereby increasing the area of ​​the inner peripheral wall 111 and improving the support effect of the support structure 23, while reducing the sharpness of the edges of the mounting holes 11 and reducing the possibility of injuring maintenance workers.

[0039] Two support structures 23 are provided for one host 2. The support structures 23 are arranged on both sides of the first mounting surface 211 in the horizontal direction. This allows the two support structures 23 to be hung on the inner peripheral wall 111 of the mounting hole 11 at both sides, improving balance and stability when the host 2 is hung.

[0040] Self-service devices are used in a wide variety of applications, including subway ticket vending machines, gas and charging stations, numbering machines in hospitals and banks, store beverage vending machines, parcel delivery and delivery storage machines, water dispensers, and coffee makers. Each of these self-service devices includes a cabinet body. The cabinet typically accommodates multiple types of host devices 200, such as a scanning device, a coin slot, a card reader, a keyboard, a display, a touch panel, and a numbering machine. These devices can be equipped with the aforementioned support structure 23, allowing a single maintenance technician to complete the installation and removal of various types of host devices.

[0041] By providing the support structure 23 and the back clip 3, when a maintenance worker attaches the host device 200 to the cabinet panel 1, the host 2 is first hooked to the front surface 101 of the cabinet panel 1 by abutting the support structure 23 of the host 2 against the inner peripheral wall 111 of the mounting hole 11. At this time, a portion of the structure of the host 2 is exposed from the mounting hole 11. Next, the worker goes around to the back surface 102 of the cabinet panel 1 and connects the back clip 3 to the portion of the host 2 exposed from the mounting hole 11. As a result, the host 2 and the back clip 3 work together to sandwich the front surface 101 and the back surface 102 of the cabinet panel 1, and the host device 200 is fixed to the cabinet panel 1.

[0042] By using the support structure 23 to hook the host 2 into the mounting hole 11, when a maintenance worker installs the host 2 on the back 102 side of the cabinet panel 1, there is no need for another maintenance worker to support the host device 200 on the front 101 side of the cabinet panel 1. This allows the entire installation work to be completed by a single maintenance worker, greatly improving the efficiency of installation, removal, and maintenance work of the self-service device.

[0043] 1, 2, and 4, in some embodiments, the host 2 includes a main body portion 21 and an attachment portion 22. The attachment portion 22 is located on the side of the main body portion 21 facing the back clip 3, and a first attachment surface 211 is provided on the main body portion 21. At least a portion of the attachment portion 22 fits into the attachment hole 11, and is detachably connected to the back clip 3.

[0044] The main body 21 has a case and functional components, including a circuit board and user-operable elements such as a keyboard, buttons, and a display connected to the circuit board.

[0045] A flat first mounting surface 211 is formed on one side of the case. The area of ​​the first mounting surface 211 can cover the area of ​​the mounting hole 11. A mounting portion 22 is protruded from the first mounting surface 211. A plurality of interfaces 221 are provided on the mounting portion 22. These interfaces 221 and electrical cables electrically connect the functional components of the main body 21 to the circuit structure of the cabinet. The area of ​​the mounting portion 22 is smaller than that of the first mounting surface 211. The thickness of the mounting portion 22 exceeds the thickness of the sheet metal of the cabinet panel 1.

[0046] The outer dimensions of the mounting portion 22 match the outer dimensions of the mounting hole 11. For example, if the mounting hole 11 is rectangular, the mounting portion 22 has a rectangular parallelepiped shape. This design makes it possible to arrange the interfaces 221 on the mounting portion 22 by making maximum use of the area of ​​the mounting hole 11, and also makes it easy to smoothly lead the cables connected to the interfaces 221 into the interior of the cabinet.

[0047] By providing main body portion 21 and mounting portion 22, first mounting surface 211 of main body portion 21 comes into close contact with front surface 101 of cabinet panel 1. This allows mounting portion 22 to penetrate deeply into mounting hole 11 and extend to rear surface 102 of cabinet panel 1, facilitating the operation of connecting back clip 3 to mounting portion 22 from the rear surface 102 side of cabinet panel 1.

[0048] 3 and 4, in some embodiments, the host device 200 includes multiple types of hosts 2, and different hosts 2 are provided with different attachment portions 22. The back clip 3 is detachably connected to any of the attachment portions 22.

[0049] A single self-service device typically has multiple types of hosts 2 installed. The types of hosts 2 include, but are not limited to, scanners, card readers, coin slot machines, touch panels, displays, etc. Because different hosts 2 have different dimensions and shapes, the number and types of connectors on the hosts 2 also vary. As a result, the external dimensions of the mounting portion 22 of different hosts 2 also vary.

[0050] The mounting portion 22 has a screw hole 24 formed therein facing toward the inside of the cabinet. The back clip 3 has a through hole 33. The back clip 3 can be connected to the mounting portion 22 by passing a screw 34 through the through hole 33 and screwing it into the screw hole 24 of the mounting portion 22. Four screw holes 24 are formed in one mounting portion 22. The four screw holes 24 are located at the four corners of the mounting portion 22, respectively. The positions of the screw holes 24 of different mounting portions 22 vary depending on the dimensions of the mounting portion 22. The back clip 3 has a plurality of through holes 33. The plurality of through holes 33 form a plurality of schemes matching the screw holes 24 so that the same back clip 3 can be adapted to a plurality of types of mounting portions 22.

[0051] When fastening the host device 200, only one set of screw holes 24 and some of the through holes 33 are used, resulting in excess through holes 33. These excess through holes 33 can be used to organize the cables on the back surface connected to the interface 221. For example, by passing the cables through the through holes 33, it is possible to organize the cable routing, or to use a binding band to combine the cables with the through holes 33 and tie them to the back clip 3. This keeps the wiring of the entire host device 200 neat and tidy, allowing maintenance workers to easily track the wiring during subsequent maintenance of the device, improving work efficiency.

[0052] By providing a versatile back clip 3, it is no longer necessary to design multiple types of back clips 3 for a single self-service device in order to attach multiple types of host devices 200. A single self-service device is typically equipped with multiple types of host devices 200, such as a scanner, card reader, coin slot machine, and touch display. The size of the host device 200 varies depending on the type. Using a versatile back clip 3 makes it easier for maintenance workers to attach the back clip 3, improving work efficiency. Furthermore, since it is no longer necessary to design multiple types of back clips 3 when manufacturing a self-service device, production efficiency is improved and parts costs can be reduced.

[0053] 5 , in some embodiments, the support structure 23 includes a fixing portion 231 and a receiving portion 232. The fixing portion 231 is connected to the first mounting surface 211. The receiving portion 232 is connected to the fixing portion 231 and is disposed at an angle to the fixing portion 231. The receiving portion 232 is used to abut against the inner circumferential wall 111.

[0054] Due to the design of the receiving portion 232, the receiving portion 232 and the first mounting surface 211 combine to form a structure that restricts movement of the host 2 in two directions. When the first mounting surface 211 is in close contact with the front surface of the cabinet panel 1, the receiving portion 232 abuts against the inner peripheral wall 111 of the mounting hole 11, and the inner peripheral wall 111 applies an upward support force to the host 2, preventing the host 2 from falling.

[0055] 5, in some embodiments, the support structure 23 further includes a blocking portion 233. The blocking portion 233 is connected to the end of the receiving portion 232 that is farther from the fixing portion 231. Moreover, the blocking portion 233 is disposed at an angle to the receiving portion 232 and extends to the rear surface 102, and is used to block horizontal displacement of the host 2.

[0056] Due to the design of the blocking portion 233, when the host 2 is hung on the inner peripheral wall 111 of the mounting hole 11, if the center of gravity of the host 2 moves away from the first mounting surface 211 and slides down, the blocking portion 233 abuts against the back surface 102 of the cabinet panel 1, preventing the host 2 from falling off and improving stability when hung. Furthermore, even if the host 2 tilts slightly when the blocking portion 233 abuts against the back surface 102 of the cabinet panel 1, the maintenance worker can adjust the position of the mounting portion 22 from the back surface 102 side of the cabinet panel 1, so the installation work of the back clip 3 is not affected.

[0057] As shown in FIG. 4, in some embodiments, the support structure 23 is a resilient structure.

[0058] By employing an elastic structure for the support structure 23 and the blocking portion 233, the host 2 can be partially displaced when the host 2 is hooked onto the inner peripheral wall 111 of the mounting hole 11 via the support structure 23 and the blocking portion 233. This allows the maintenance worker to fine-tune the relative positions of the host 2 and the back clip 3 when attaching the back clip 3 on the rear surface 102 side of the cabinet panel 1, and the operation is not restricted by the support structure 23 or the blocking portion 233, improving attachment efficiency.

[0059] 4, in some embodiments, a plurality of coupling holes (not shown) are provided in the first mounting surface 211. The support structure 23 is detachably connected to any of the coupling holes.

[0060] The processing precision of the mounting holes 11 of some cabinets may not be high. Furthermore, when replacing the host 2, the model of the host 2 may be different, and the dimensions of the original mounting hole 11 and the current host 2 may not perfectly match. As a result, when the original support structure 23 is hung on the inner peripheral wall 111 of the mounting hole 11, the mounting portion 22 may not be fully exposed through the mounting hole 11 to the rear surface 102 of the cabinet panel 1. In such cases, the relative positions of the mounting portion 22 and the mounting hole 11 can be adjusted by changing the mounting position of the support structure 23.

[0061] By providing multiple connecting holes, if a maintenance worker finds that the shape of the actual mounting hole 11 is not as designed, he or she can remove the support structure 23 and adjust the relative positions of the support structure 23 and the host 2 to match the position of the inner wall 111 of the actual mounting hole 11. Because there are multiple standard specifications for the mounting holes 11 of the cabinet panel 1, designing the positions of multiple connecting holes to match these specifications makes it possible to adapt the host 2 to mounting holes 11 of different specifications. Furthermore, even if the support structure 23 is damaged during the production process or transportation, only the support structure 23 can be replaced, thereby reducing item costs.

[0062] 2, in some embodiments, a first magnetic attraction member (not shown) is provided on the first mounting surface 211. A second magnetic attraction member is provided on the cabinet panel 1, or the cabinet panel 1 itself is made of a magnetic attraction material.

[0063] A magnet is embedded in the first mounting surface 211. The cabinet panel 1 is typically made of an iron-containing material such as stainless steel or galvanized steel. Therefore, the first mounting surface 211 can be magnetically attached to the front surface 101 of the cabinet panel 1, thereby reducing the supporting force borne by the support structure 23. Alternatively, a magnet can be installed at a corresponding position on the back surface 102 of the cabinet panel 1, and the magnet on the first mounting surface 211 and the magnet on the cabinet panel 1 can interact with each other to magnetically attach the host 2 to the cabinet panel 1.

[0064] By adopting the magnetic adsorption method, the first mounting surface 211 is more firmly connected to the cabinet panel 1 and will not easily fall off.

[0065] 2 and 3, in some embodiments, the back clip 3 is provided with a second mounting surface 31. The second mounting surface 31 is disposed so as to surround the mounting hole 11 and is in close contact with the back surface 102.

[0066] The back clip 3 has a frame structure. The second mounting surface 31 of the back clip 3 has a "round" shape. When viewed from the front of the cabinet panel 1, the projection of the second mounting surface 31 surrounds the mounting hole 11. The cutout portion of the back clip 3 is used to avoid the cable connected to the connector.

[0067] By setting the second mounting surface 31 to a shape that surrounds the mounting hole 11, when the host 2 and the back clip 3 sandwich the cabinet panel 1, it becomes possible to sandwich the entire inner wall 111 where the mounting hole 11 is located, thereby improving the connection strength between the host 2 and the back clip 3.

[0068] See Figure 2. In some embodiments, the second mounting surface 31 is provided with a recess 32, which is used to accommodate the support structure 23.

[0069] The depth and width of the retraction groove 32 are sized to accommodate the support structure 23, and when the second mounting surface 31 is in close contact with the back surface 102 of the cabinet panel, the support structure 23 will not abut against the back clip 3 within the retraction groove 32. The retraction groove 32 forms a notch 321 on the outer edge of the frame of the back clip 3, allowing the blocking portion 233 to move through the notch 321 within the retraction groove 32. As a result, when a maintenance worker adjusts the position of the back clip 3 to align it with the mounting portion 22, the blocking portion 233 does not interfere with the movement of the back clip 3.

[0070] By providing the escape groove 32, when connecting the back clip 3 to the host 2, the support structure 23 and the blocking portion 233 are accommodated in the escape groove 32, so that the second mounting surface 31 is not prevented from coming into close contact with the back surface 102 of the cabinet panel 1. This improves the connection strength between the back clip 3 and the host 2.

[0071] 2, in some embodiments, the second mounting surface 31 has a symmetrical shape and includes a plurality of recessed grooves 32 formed in the second mounting surface 31. Some of the recessed grooves 32 are configured to accommodate the support structure 23.

[0072] The back clip 3 has a frame structure, and with a line passing through the midpoints of two opposing sides of the back clip 3 as an axis of symmetry, the retraction grooves 32 are arranged symmetrically along another pair of opposing sides.

[0073] By designing the escape groove 32 symmetrically, the escape groove 32 can accommodate the support structure 23 whether the back clip 3 is mounted properly or inverted when attaching the back clip 3 to the host 2. This eliminates the need for a maintenance worker to take the trouble of aligning the escape groove 32 with the support structure 23, thereby reducing the work time.

[0074] It should be noted that those skilled in the art should recognize that the above embodiments are for the purpose of illustrating the present application, and are not intended to limit the present application. Any appropriate modifications and variations to the above embodiments within the true spirit of the present application are included in the disclosure scope of the present application.
