Description

Technical Field

[0001] The invention relates to an electrical connection device with a floating structure and a charging compartment thereof. Background Art

[0002] Existing battery installation methods for electric vehicles are generally divided into fixed and replaceable types. Fixed batteries are generally fixed to the vehicle and directly charge the vehicle. Replaceable batteries, on the other hand, are generally removable and can be removed at any time and placed in a charging compartment for replacement or charging. After replacement or charging, they can be installed back into the vehicle.

[0003] In patent publication CN108063345A, the terminals are mounted on a floating plate, which is connected to a fixed plate via springs on all sides. However, because the top and bottom ends of the floating plate are connected to the fixed plate via springs, the overall height of the electrical connector is relatively large, resulting in a large footprint. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the existing electrical connector has a large overall height and occupies a large area, and to provide an electrical connection device with a floating structure and a charging compartment thereof.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] An electrical connection device with a floating structure includes a fixed plate and a floating plate. The floating plate is mounted with poles for electrical connection. Both ends of the floating plate have a set of floating connection portions protruding outward. The electrical connection device with a floating structure also includes two sets of elastic connectors. The ends of the elastic connectors are respectively connected to the floating connection portions and the fixed plate, so that the floating plate can be movably mounted on the fixed plate.

[0007] In this solution, the aforementioned structure is employed, with floating connections connected to elastic connectors only at the ends of the floating plate, while neither floating connections nor elastic connectors are present above or below. This reduces the overall height of the floating electrical connection device, resulting in a smaller footprint. This floating electrical connection device allows for a greater number of stacked battery racks, enabling the electrical connection and charging of more battery packs. Furthermore, the floating plate is connected to the elastic connectors via floating connections, allowing for replacement and adjustment of the elastic connectors, making maintenance and replacement very convenient and cost-effective.

[0008] Preferably, the two groups of floating connection parts are symmetrically arranged at both ends of the floating plate along the length direction thereof.

[0009] In this solution, the above-mentioned structural form is adopted, and the two groups of floating connection parts are symmetrically arranged at both ends of the floating plate along the length direction of the floating plate, so that the floating plate is evenly stressed at both ends in the length direction and has higher stability.

[0010] Preferably, a group of connection ports are provided at both ends of the fixed plate, the elastic connection member is located in the connection port, and the floating connection portion extends into the connection port and is movably connected to the edge of the connection port through the elastic connection member.

[0011] In this solution, the above-mentioned structural form is adopted, and the elastic connector is arranged in the connecting port opened by the fixed plate. The floating plate extends into the connecting port through the floating connection part and is connected to the elastic connector, so that each elastic connector is located in the same plane and in a non-deformed state when the electrical connection device is in the initial state, thereby extending the service life of the elastic connector and effectively reducing the overall thickness of the electrical connection device with a floating structure. The structure is more compact and the occupied area is further reduced.

[0012] In addition, the elastic connector is movably connected to the edge of the connection port. The edge of the connection port abuts against the elastic connector and restricts the movement of the floating plate, further improving the safety and stability of the electrical connection device with a floating structure.

[0013] Preferably, the floating connection portion is in the shape of a cross, and includes a first connection member and a second connection member that intersect perpendicularly, wherein the first connection member and the second connection member are both located at positions corresponding to the connection port, the first end of the first connection member is connected to the end of the floating plate, and the second end of the first connection member is connected to the second connection member and extends outward.

[0014] In this solution, the above-mentioned structure is adopted. The second end of the first connector is connected to the corresponding connection port on the fixed plate via an elastic connector. The elastic connectors connecting the first connectors at both ends of the floating plate enable the floating plate to float left and right. A second connector is connected perpendicularly to the first connector and connected to the corresponding connection port on the fixed plate via an elastic connector. The elastic connectors at the upper and lower ends of the second connector enable the floating plate to float up and down. This allows the floating plate to float in all directions and achieves greater stability. Furthermore, the structure is simple and easy to assemble.

[0015] Preferably, the second connecting member is located in the connecting port, the first end of the first connecting member is connected to the end of the floating plate, and the second end of the first connecting member extends into the connecting port and is connected to the second connecting member.

[0016] In the present solution, the above-mentioned structural form is adopted, the second end of the first connecting member extends into the connecting port and is connected to the connecting port through an elastic connecting member, the second connecting member is connected to the second end of the first connecting member and is connected to the connecting port through an elastic connecting member, so that each elastic connecting member is located in the connecting port, and is located in the same plane and non-deformed state when the electrical connecting device is in the initial state, thereby extending the service life of the elastic connecting member and effectively reducing the overall thickness of the electrical connecting device with a floating structure, making the structure more compact and further reducing the occupied area.

[0017] Preferably, the floating plate is provided on a surface of one side of the fixed plate, and the first end of the first connector is stepped so that the second end of the first connector and the second connector are aligned with the edge of the connector when both extend into the connector.

[0018] In the present solution, the above-mentioned structural form is adopted, and by designing the first end of the first connecting member into a stepped shape, the floating plate can be located on one side of the fixed plate and can float on the side of the fixed plate. At the same time, the second end of the first connecting member and the second connecting member are aligned with the edge of the connecting port when both extend into the connecting port, effectively avoiding protrusion from the outer surface of the fixed plate to occupy space resources and avoid interference, thereby improving the safety and stability of the electrical connection device with a floating structure.

[0019] Preferably, connecting posts are provided on the edge of the connecting port corresponding to the second end of the first connecting member and both ends of the second connecting member.

[0020] In this solution, the above-mentioned structural form is adopted, and the connecting column has a positioning and connecting function. The elastic connecting piece is sleeved on the connecting column to achieve precise positioning and installation. The installation and connection are convenient, and the elastic connecting piece is effectively avoided from being offset and detached during use, thereby greatly improving the stability of the electrical connection device with a floating structure.

[0021] Preferably, connecting columns are provided at the edge of the connecting port corresponding to the second end of the first connecting member and the two ends of the second connecting member, and the connecting columns are stepped in shape. The first end of the connecting column is located in the connecting port and connected to the edge of the connecting port, and the second end of the connecting column extends out of the connecting port and is aligned with the second end of the first connecting member and the two ends of the second connecting member.

[0022] In this embodiment, the above-mentioned structural form is adopted, and the first connector does not extend into the connection port. Instead, the first connector is arranged outside the connection port and located at a corresponding position of the connection port, making the floating connection portion simple in structure and very convenient to manufacture. Furthermore, the floating connection portion of the floating plate will not touch the inner wall surface of the connection port during use, greatly improving the safety and stability of the electrical connection device with a floating structure. At the same time, the connecting column has a positioning connection function, achieving precise positioning and installation, facilitating installation and connection, and effectively preventing the elastic connector from deviating and detaching during use, greatly improving the stability of the electrical connection device with a floating structure. When the electrical connection device is in the initial state, each elastic connector is located in the same plane and in a non-deformed state. That is, each elastic connector is subjected to minimal force when the electrical connection device is in the initial state, which helps to extend the service life of the elastic connector. It can also effectively reduce the overall thickness of the electrical connection device with a floating structure, making the structure more compact and further reducing the occupied area.

[0023] Preferably, one end of the elastic connector is sleeved on the connecting post, and the other end is sleeved on the second end of the first connector and two end portions of the second connector corresponding to the connecting post.

[0024] The number of the elastic connectors in each group is three, wherein the ends of two of the elastic connectors are respectively sleeved on the two ends of the second connector, and the other elastic connector is sleeved on the second end of the first connector.

[0025] In this solution, the above-mentioned structure is adopted, and each group of three elastic connectors is respectively mounted on both ends of the second connector and the second end of the first connector, so that the floating plate is subjected to forces on all sides, thereby improving stability. At the same time, the structure is simple and assembly is very convenient.

[0026] Preferably, the connection port is in a T-shape.

[0027] In this solution, the above-mentioned structural form is adopted, and the shape of the connecting port is T-shaped so that the second end of the first connecting member and both ends of the second connecting member are accommodated in the connecting port. It is easy to process and manufacture, and the area of ​​the connecting port is minimized, thereby ensuring the overall structural strength of the fixed plate.

[0028] Preferably, the pole is mounted on the floating plate through a pole mounting plate, the pole mounting plate is provided with a mounting hole for the pole to pass through and be installed, the fixed plate and the floating plate are respectively provided with a first mounting opening and a second mounting opening at positions corresponding to the pole mounting plate, the pole mounting plate is passed through the second mounting opening and extends into the first mounting opening.

[0029] In this solution, the above-mentioned structural form is adopted, and the pole mounting plate is passed through the second mounting opening and extends into the first mounting opening, which can effectively reduce the overall thickness of the electrical connection device with a floating structure, make the structure more compact, and further reduce the occupied area; at the same time, the installation and setting are very convenient, and the stability of the pole is guaranteed.

[0030] Preferably, the two groups of connection ports are symmetrically arranged on both sides of the first installation port.

[0031] In this solution, the above-mentioned structural form is adopted. The pole will pass through the first installation opening. The two sets of elastic connectors and the two sets of floating connectors are respectively located in the two sets of connection openings. The two sets of connection openings are symmetrically arranged on both sides of the first installation opening. This ensures that the floating plate is evenly stressed and has higher stability. At the same time, interference between the elastic connector and the pole is avoided, greatly improving the safety and stability of the electrical connection device with a floating structure.

[0032] Preferably, the floating plate has a limiting post protruding from one side surface of the fixed plate, the fixed plate is provided with a limiting hole corresponding to the limiting post, the diameter of the limiting hole is larger than the outer diameter of the limiting post, the limiting hole is sleeved on the limiting post and is used to limit the range of movement of the floating plate relative to the fixed plate;

[0033] Alternatively, the fixed plate extends a limiting column toward one side of the floating plate, and the floating plate is provided with a limiting hole corresponding to the limiting column, and the aperture of the limiting hole is larger than the outer diameter of the limiting column; the limiting column is inserted into the limiting hole and is used to limit the range of movement of the floating plate relative to the fixed plate.

[0034] In this solution, the above-mentioned structural form is adopted, and a limiting hole is arranged on the limiting column to play a limiting role, thereby limiting the range of movement of the floating plate relative to the fixed plate, thereby effectively avoiding damage caused by excessive displacement and dislocation of the floating plate during movement, and further improving the safety and stability of the electrical connection device with a floating structure.

[0035] Preferably, the limiting column includes a limiting portion and a fixing portion connected to each other, the limiting portion is inserted into the limiting hole in the fixed plate or the floating plate, and the fixing portion is connected to the floating plate or the fixed plate.

[0036] In this solution, the above structural form is adopted, which has a simple structure and is very convenient to install and set up.

[0037] Preferably, the limiting portion includes a shoulder and a column, the shoulder is connected to the first end surface of the column and protrudes outward from the outer circumferential surface of the column along the radial direction of the column, and the second end surface of the column is provided with a first threaded hole recessed inwardly;

[0042] A charging compartment includes the electrical connection device with a floating structure as described above.

[0043] In this solution, the aforementioned structure is employed, with floating connections only at the ends of the floating plate, and no floating connections above or below. This reduces the overall height of the floating electrical connection device, resulting in a smaller footprint. Therefore, while the height of the battery rack remains constant, the placement of these charging compartments along the height of the battery rack compresses the height of each layer, thereby increasing the number of battery racks and enabling the charging of more battery packs. Furthermore, the elastic connectors can be replaced and adjusted, making maintenance and replacement very convenient and cost-effective.

[0044] On the basis of conforming to the common sense in this field, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0045] The positive progress effect of the present invention is:

[0078] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0079] Example 1

[0080] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, an electrical connection device with a floating structure according to an embodiment of the present invention includes a fixed plate 1 and a floating plate 2. The floating plate 2 is mounted with a pole 3 for electrical connection. Both ends of the floating plate 2 have a set of outwardly protruding floating connection portions 21. The electrical connection device with a floating structure also includes two sets of elastic connectors 4. The ends of the elastic connectors 4 are respectively connected to the floating connection portions 21 and the fixed plate 1, so that the floating plate 2 can be movably mounted on the fixed plate 1.

[0081] By only having floating connections 21 connected to the elastic connector 4 at the left and right ends of the floating plate 2, while not having either of these at the top and bottom ends, the overall height of the floating electrical connection device is reduced, resulting in a smaller footprint. This floating electrical connection device allows for more stacked battery racks, enabling the electrical connection and charging of more battery packs. Furthermore, the floating plate 2 is connected to the elastic connector 4 via the floating connections 21, allowing for easy replacement and adjustment of the elastic connector 4, making maintenance and replacement very convenient and cost-effective.

[0082] In this embodiment, two sets of floating connection portions 21 are symmetrically disposed at both ends of the floating plate 2 along its length. By symmetrically disposing the two sets of floating connection portions 21 at both ends of the floating plate 2 along its length, the floating plate 2 is subjected to uniform force at both ends of its length, thereby enhancing stability.

[0083] A set of connection openings 11 are provided at both ends of the fixed plate 1. Elastic connectors 4 are located within the connection openings 11. Floating connectors 21 extend into the connection openings 11 and are flexibly connected to the edges of the connection openings 11 via the elastic connectors 4. The elastic connectors 4 are positioned within the connection openings 11 defined in the fixed plate 1, and the floating plate 2 extends into the connection openings 11 via the floating connectors 21, connecting to the elastic connectors 4. This ensures that each elastic connector 4 is located in the same plane and in a non-deformed state when the electrical connection device is in its initial state. This means that each elastic connector 4 is subjected to minimal force when the electrical connection device is in its initial state, extending the service life of the elastic connectors 4. This also effectively reduces the overall thickness of the electrical connection device with a floating structure, making the structure more compact and further reducing its footprint. Furthermore, the elastic connectors 4 are flexibly connected to the edges of the connection openings 11, with the edges of the connection openings 11 abutting against the elastic connectors 4 and restricting the movement of the floating plate 2, further enhancing the safety and stability of the electrical connection device with a floating structure.

[0084] The floating connection 21 is cross-shaped and includes a first connector 211 and a second connector 212, both of which intersect perpendicularly. The first connector 211 and the second connector 212 are located at positions corresponding to the connection port 11. The first end of the first connector 211 is connected to the end of the floating plate 2, while the second end of the first connector 211 is connected to the second connector 212 and extends outward. The second end of the first connector 211 is connected to the connection port 11 at a corresponding position on the fixed plate 1 via an elastic connector 4. The elastic connector 4 connecting the first connector 211 at both ends of the floating plate 2 enables the floating plate 2 to float left and right. The second connector 212 is connected perpendicularly to the first connector 211 and connected to the connection port 11 at a corresponding position on the fixed plate 1 via the elastic connector 4. The elastic connector 4 at the upper and lower ends of the second connector 212 enables the floating plate 2 to float up and down. This allows the floating plate 2 to float in all directions and achieves greater stability. Furthermore, the structure is simple and easy to assemble.

[0085] In one embodiment, the second connector 212 is located within the connection port 11. The first end of the first connector 211 is connected to the end of the floating plate 2, and the second end of the first connector 211 extends into the connection port 11 and is connected to the second connector 212. The second end of the first connector 211 extends into the connection port 11 and is connected to the connection port 11 via the elastic connector 4. The second connector 212 is connected to the second end of the first connector 211 and is connected to the connection port 11 via the elastic connector 4. This ensures that the elastic connectors 4 are located within the connection port 11 and are in the same plane and non-deformed when the electrical connection device is in the initial state. This extends the service life of the elastic connectors 4 and effectively reduces the overall thickness of the electrical connection device with a floating structure, making the structure more compact and further reducing the occupied area.

[0086] The floating plate 2 is positioned on a surface on one side of the fixed plate 1. The first end of the first connector 211 is stepped, ensuring that the second end of the first connector 211 and the second connector 212 are aligned with the edge of the connection port 11 when both are inserted into the connection port 11. By designing the first end of the first connector 211 as a stepped shape, the floating plate 2 can be positioned on one side of the fixed plate 1 and float there. Furthermore, the second end of the first connector 211 and the second connector 212 are aligned with the edge of the connection port 11 when both are inserted into the connection port 11. This effectively prevents the floating plate 2 from protruding from the outer surface of the fixed plate 1, taking up space, and preventing interference, thereby improving the safety and stability of the electrical connection device with a floating structure.

[0087] In this embodiment, connecting posts 12 are provided along the edge of the connection port 11, corresponding to the second end of the first connector 211 and both ends of the second connector 212. The connecting posts 12 serve as a positioning connection. By fitting the elastic connector 4 over the connecting posts 12, precise positioning and installation are achieved, making installation and connection convenient. This effectively prevents the elastic connector 4 from drifting or disengaging during use, significantly improving the stability of the floating electrical connection device.

[0088] One end of the elastic connector 4 is sleeved onto the connecting post 12, and the other end is sleeved onto the second end of the first connector 211 and both ends of the second connector 212 corresponding to the connecting post 12. Each set of elastic connectors 4 comprises three, with two elastic connectors 4 sleeved onto both ends of the second connector 212, and one elastic connector 4 sleeved onto the second end of the first connector 211. By sleeved onto both ends of the second connector 212 and the second end of the first connector 211, each set of three elastic connectors 4 ensures that forces are applied on all sides of the floating plate 2, enhancing stability. Furthermore, the structure is simple and assembly is very convenient.

[0089] In one embodiment, the connection port 11 is shaped like a T. The T-shaped connection port 11 accommodates the second end of the first connection member 211 and both ends of the second connection member 212 within the connection port 11, facilitating processing and manufacturing, minimizing the area of ​​the connection port 11, and ensuring the overall structural strength of the fixing plate 1.

[0090] The pole 3 is mounted on the floating plate 2 via a pole mounting plate 5. The pole mounting plate 5 has mounting holes through which the pole 3 is installed. The fixed plate 1 and floating plate 2 have first and second mounting openings 13 and 22, respectively, at locations corresponding to the pole mounting plate 5. The pole mounting plate 5 is inserted into the second mounting opening 22 and extends into the first mounting opening 13. The pole 3 is first installed and secured in the mounting hole of the pole mounting plate 5. The pole mounting plate 5 is then mounted on the floating plate 2. With the pole mounting plate 5 inserted into the second mounting opening 22 and into the first mounting opening 13, the overall thickness of the floating electrical connection device is effectively reduced, resulting in a more compact structure and a smaller footprint. Furthermore, installation is very convenient and the stability of the pole 3 is ensured.

[0091] The two sets of connection openings 11 are symmetrically arranged on either side of the first mounting opening 13. The pole 3 passes through the first mounting opening 13. The two sets of elastic connectors 4 and the two sets of floating connectors 21 are located within the two sets of connection openings 11. The symmetrical arrangement of the two sets of connection openings 11 on either side of the first mounting opening 13 ensures uniform force distribution on the floating plate 2, enhancing stability. This also prevents interference between the elastic connectors 4 and the pole 3, significantly improving the safety and stability of the floating electrical connection device.

[0092] In this embodiment, a limiting post 23 protrudes from one side of the floating plate 2 toward the fixed plate 1. A limiting hole 14 is defined in the fixed plate 1 corresponding to the limiting post 23. The diameter of the limiting hole 14 is larger than the outer diameter of the limiting post 23. The limiting hole 14 is inserted into the limiting post 23 and serves to limit the range of motion of the floating plate 2 relative to the fixed plate 1. By inserting the limiting hole 14 into the limiting post 23, the limiting hole 14 acts to restrict the range of motion of the floating plate 2 relative to the fixed plate 1, thereby effectively preventing damage caused by excessive displacement or misalignment of the floating plate 2 during movement, further improving the safety and stability of the electrical connection device with a floating structure. Of course, in other embodiments, a limiting post protrudes from one side of the fixed plate 1 toward the floating plate 2. The floating plate 2 defines a limiting hole corresponding to the limiting post. The diameter of the limiting hole is larger than the outer diameter of the limiting post. The limiting post is inserted into the limiting hole and serves to limit the range of motion of the floating plate 2 relative to the fixed plate 1.

[0093] The limiting post 23 includes a limiting portion 231 and a fixing portion 232 that are interconnected. The limiting portion 231 is inserted into the limiting hole 14 in the fixed plate 1 or the floating plate 2, and the fixing portion 232 is connected to the floating plate 2 or the fixed plate 1. In this embodiment, the limiting portion 231 and the fixing portion 232 are connected to achieve the connection of the fixing portion 232 to the floating plate 2. The limiting portion 231 is inserted into the limiting hole 14 of the fixed plate 1, resulting in a simple structure and very convenient installation.

[0094] The limiting portion 231 includes a shoulder 2311 and a column 2312. The shoulder 2311 is connected to the first end face of the column 2312 and protrudes outward from the outer circumferential surface of the column 2312 along the radial direction of the column 2312. The second end face of the column 2312 is provided with a first threaded hole recessed inward; the fixing portion 232 is a bolt; a second threaded hole 24 is provided on one of the fixed plate 1 or the floating plate 2; the limiting hole 14 is a through hole, and the through hole is provided on the other of the fixed plate 1 or the floating plate 2, and the shoulder 2311 is used to abut against the other of the fixed plate 1 or the floating plate 2 to limit the shoulder 2311 from extending into the through hole; the column 2312 extends into the through hole, and the bolt is screwed into the second threaded hole 24 and the first threaded hole in sequence.

[0095] First, insert the limiting portion 231 into the through-hole of the fixed plate 1. Then, extend the column 2312 into the through-hole. The shoulder 2311 abuts the side of the fixed plate 1, ensuring that the limiting portion 231 and the fixed plate 1 are in contact. This facilitates installation and allows for precise positioning. Then, a bolt is screwed from the second threaded hole 24 of the floating plate 2 into the first threaded hole of the column 2312, completing the installation of the limiting column 23. This simple structure allows for easy installation and high stability.

[0096] The embodiment of the present invention also discloses a charging pod, which includes the electrical connection device with a floating structure as described above. By only having floating connection parts 21 at the left and right ends of the floating plate 2 and not having floating connection parts 21 at the upper and lower ends, the overall height of the electrical connection device with a floating structure is reduced, and the height occupies a small area. Therefore, when the height of the battery rack remains unchanged, arranging such a charging pod along the height direction of the battery rack can compress the height of each layer of the battery rack, thereby increasing the number of layers of the battery rack to achieve the purpose of charging more battery packs. At the same time, the elastic connector 4 can be replaced and adjusted, and maintenance and replacement are very convenient and low-cost.

[0097] Example 2

[0098] like Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the same parts of the electrical connection device with a floating structure in this embodiment as in embodiment 1 will not be repeated, and only the differences will be described. In this embodiment 2, each elastic connection member 4 is not disposed inside the connection port 11 but outside the connection port 11.

[0099] A connecting column 12 is provided at the edge of the connecting port 11 corresponding to the second end of the first connecting member 211 and both ends of the second connecting member 212. The connecting column 12 is in a stepped shape. The first end of the connecting column 12 is located inside the connecting port 11 and is connected to the edge of the connecting port 11. The second end of the connecting column 12 extends out of the connecting port 11 and is aligned with the second end of the first connecting member 211 and both ends of the second connecting member 212.

[0100] In this embodiment, the first connector 211 does not extend into the connection port 11. Instead, it is positioned outside the connection port 11 and located at a corresponding position therewith. This simplifies the structure of the floating connection portion 21 and makes it very easy to manufacture. Furthermore, during use of the floating plate 2, the floating connection portion 21 does not contact the inner wall of the connection port 11, significantly improving the safety and stability of the floating electrical connection device. Furthermore, the connection post 12 serves as a positioning connection. By fitting the elastic connector 4 onto the connection post 12, precise positioning and installation are achieved, making installation and connection easy and effectively preventing the elastic connector 4 from drifting or disengaging during use, significantly improving the stability of the floating electrical connection device. Furthermore, the shape of the connecting column 12 is stepped, so that when the floating plate 2 is in contact with the fixed plate 1, the second end of the connecting column 12 is flush with the floating connection portion 21; alternatively, when the floating plate 2 is not subjected to external force, the second end of the connecting column 12 is flush with the floating connection portion 21, so that when the electrical connection device is in the initial state, each elastic connector 4 is located in the same plane and in a non-deformed state, that is, when the electrical connection device is in the initial state, each elastic connector 4 is subjected to the minimum force, which extends the service life of the elastic connector 4 and can effectively reduce the overall thickness of the electrical connection device with a floating structure, making the structure more compact and further reducing the occupied area.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
