Description

Technical Field

[0001] This disclosure relates to the field of vehicle roll cage technology, and more particularly to a semi-cage roll cage and a vehicle. Background Technology

[0002] A roll cage is a protective structure installed on the vehicle body to improve the safety of the passenger compartment under extreme conditions such as rollover and collision. In related technologies, to ensure the strength of the roll cage, it is usually constructed to extend from the front row to the rear row, which is complex. This structure greatly restricts the posture of the driver and passengers, resulting in poor driving and riding comfort. Furthermore, the roll cage is usually a welded, non-removable whole, and its large size makes it difficult to install, remove, and access the vehicle body. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides a semi-cage roll cage and a vehicle.

[0004] According to a first aspect of the present disclosure, a semi-cage roll cage is provided, comprising:

[0005] A first support frame is used to install at a position corresponding to the B-pillar of the vehicle body, and to support the B-pillar, the roof assembly of the vehicle body, and the floor assembly of the vehicle body; and

[0006] A second support frame extends backward and downward from the first support frame to connect to the vehicle body; the first support frame and the second support frame are detachably connected.

[0007] Optionally, the top end of the second support frame is detachably connected to the first support frame near its top end.

[0008] Optionally, the first support frame includes:

[0009] A first crossbar is used to support the top cover assembly from the bottom; and

[0010] Two first vertical bars support the corresponding B-pillars from the inside. The top ends of the two first vertical bars are connected to the two ends of the first horizontal bar, and the bottom ends of the two first vertical bars are used to connect to the base plate assembly.

[0011] Optionally, the first support frame further includes:

[0012] The second horizontal bar connects the two first vertical bars; and

[0013] Two first diagonal braces are provided, each with one end connected to a corresponding first vertical bar near its bottom, and the other end extending diagonally upwards and connecting to a first horizontal bar near its end. This allows the second horizontal bar and the two first diagonal braces to intersect and form a radial force transmission path.

[0014] Wherein, a first reinforcing corner brace is provided at the angle formed between the two first diagonal bars and the first horizontal bar, and / or a second reinforcing corner brace is provided at the angle formed between two of the two first diagonal bars and the second horizontal bar.

[0015] Optionally, the bottom ends of the two first vertical rods are respectively provided with first mounting seats, which are used for detachable connection with the base plate assembly.

[0016] Optionally, the second support frame includes two second vertical rods, the bottom ends of which are respectively connected to the base plate assembly, and the top ends of which respectively extend obliquely upward and are connected to the first crossbar near its two ends.

[0017] Optionally, the bottom ends of the two second vertical rods are respectively provided with second mounting seats, which are used for detachable connection with the base plate assembly.

[0018] Optionally, the second support frame further includes two second diagonal rods, one end of which is connected to the bottom of a corresponding second vertical rod, and the other end extends obliquely upward and is connected to the top of another second vertical rod, so that the two second diagonal rods intersect to form an X-shaped force transmission path.

[0019] Optionally, the first support frame is provided with two joint struts, and the top ends of the two second vertical rods are respectively connected to the corresponding joint struts.

[0020] Optionally, the top end of the second vertical rod forms a first semi-cylindrical joint, and the end of the joint support rod away from the first support frame forms a second semi-cylindrical joint.

[0021] The first semi-cylindrical joint and the second semi-cylindrical joint are connected to form a cylindrical segment coaxial with the joint support rod.

[0022] According to a second aspect of the present disclosure, a vehicle is provided, including the aforementioned semi-cage roll cage.

[0023] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: They can improve ride comfort while ensuring the structural strength of the semi-cage roll cage. Specifically, the first support frame is installed on the vehicle body at the position corresponding to the B-pillar, and the second support frame is located behind the first support frame. The semi-cage roll cage as a whole does not need to occupy the A-pillar and front compartment area, thus ensuring the comfort of the occupants. Simultaneously, a second support frame extending downwards at an angle is provided behind the first support frame, forming a triangular support structure, which can effectively enhance the overall strength of the semi-cage roll cage, thereby preventing the collapse and intrusion of the vehicle's B-pillar and roof structure during rollover, providing comprehensive protection for the safety of the occupants. Furthermore, the first and second support frames are detachably connected, allowing them to be installed separately to the vehicle body first, and then connected as a whole. Similarly, during disassembly, simply disconnect the connection points of the two components and remove them from the vehicle body. During the disassembly and assembly process, the first and second support frames can enter and exit through the rear door openings respectively, without the need to disassemble other parts of the vehicle body to provide access space. This makes the installation and disassembly of the semi-cage roll cage more convenient and faster, minimizing the space requirements for the installation path.

[0024] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0032] Reference Figure 1 Figure 3 This disclosure exemplarily illustrates a semi-cage roll cage, including a first support frame 1 and a second support frame 2. The first support frame 1 is installed at a position corresponding to the B-pillar of the vehicle body and supports the B-pillar, the roof assembly, and the floor assembly of the vehicle body. Here, the roof assembly refers to the roof, roof frame, and other related components located at the top of the vehicle body, while the floor assembly refers to the floor, sill beam, and other related components located at the bottom of the vehicle body. The "support" here can be a direct abutment support, or it can have a certain gap and provide abutment when the B-pillar or roof assembly collapses inward. The second support frame 2 extends backward and downward from the first support frame 1 to connect to the vehicle body. Specifically, it can be connected to the floor assembly of the vehicle body, or it can be connected to the rear longitudinal beam, etc. This disclosure does not limit this. The first support frame 1 and the second support frame 2 are detachably connected, for example, by fasteners such as bolts.

[0033] It should be explained that the above "position corresponding to the B-pillar of the vehicle body" refers to the position of the vehicle body in the front-rear direction corresponding to the B-pillar, that is, the first support frame 1 is located at the corresponding position of the B-pillar (behind the front seat mounting position), and the first support frame 1 does not occupy the A-pillar area or the front driver's seat space.

[0034] This disclosure does not impose any restrictions on the specific structure of the first support frame 1 and the second support frame 2, as long as the first support frame 1 can be installed between the two B-pillars, the roof assembly, and the base plate assembly to resist deformation in the direction of the B-pillars and the roof assembly. Similarly, the second support frame 2 only needs to extend backward and downward from the first support frame 1 to form a triangular support effect. The specific structure of the two support frames will be described exemplarily below.

[0035] By using the above technical solution, the structural strength of the semi-cage roll cage can be guaranteed while improving ride comfort. Specifically, the first support frame 1 is installed on the vehicle body at the position corresponding to the B-pillar, and the second support frame 2 is located behind the first support frame 1. The semi-cage roll cage as a whole does not occupy the A-pillar and front compartment area of ​​the vehicle, thus ensuring the comfort of the occupants. At the same time, the second support frame 2, which extends downward at an angle, is set behind the first support frame 1 to form a triangular support structure, which can effectively enhance the overall strength of the semi-cage roll cage, thereby preventing the collapse and intrusion of the vehicle's B-pillar and roof structure during rollover, providing comprehensive protection for the safety of the occupants. In addition, the first support frame 1 and the second support frame 2 are designed to be detachably connected. During installation, they can be installed separately to the vehicle body first, and then connected as a whole. Similarly, during disassembly, it is only necessary to disassemble the connection points of the two and remove them from the vehicle body respectively. During the disassembly and assembly process, the first support frame 1 and the second support frame 2 can enter and exit through the rear door opening respectively without disassembling other parts of the vehicle body to provide access space, thus making the installation and disassembly of the semi-cage roll cage more convenient and faster, minimizing the space requirements of the installation path.

[0036] Reference Figure 1 In some embodiments of this disclosure, the top end of the second support frame 2 can be detachably connected to the first support frame 1 near its top end. This design, placing the connection point near the top end, allows the second support frame 2 to provide greater support force to the first support frame 1 along the vehicle height direction, thereby improving the deformation resistance of the semi-cage roll cage to the roof assembly of the vehicle body.

[0037] As described above, this disclosure does not limit the specific structure of the first support frame 1 and the second support frame 2. The structure of the two and the specific connection method between them will be limited below in conjunction with specific embodiments.

[0038] Reference Figure 1 and Figure 2In embodiments of this disclosure, the first support frame 1 may include a first horizontal bar 101 for supporting the roof assembly from the bottom and two first vertical bars 102 for supporting the corresponding B-pillars from the inside. The top ends of the two first vertical bars 102 may be connected to the two ends of the first horizontal bar 101, and the bottom ends of the two first vertical bars 102 may be used to connect to the base plate assembly. In this embodiment, the first horizontal bar 101 and the two first vertical bars 102 may form a gantry-shaped profile that matches the shape of the B-pillar and roof assembly of the vehicle body, thereby providing support for the corresponding parts on the inside and bottom sides. It should be noted that "bottom" here refers to the position near the lower side in the height direction of the vehicle body, and "inside" refers to the side near the centerline of the vehicle body in the width direction. The two first vertical bars 102 and the first horizontal bar 101 may be integrally formed or welded together. The two first vertical bars 102 and the first horizontal bar 101 are not absolutely straight bars, and their extension trajectories may be adaptively designed according to the B-pillar and roof assembly.

[0039] It should be noted that the first horizontal bar 101 and the two first vertical bars 102, as well as other members mentioned below, can all be hollow steel pipes, etc., and this disclosure does not impose any restrictions on them. Specific designs can be adapted to meet structural strength and lightweight requirements.

[0040] To enhance the structural strength of the first support frame 1 and improve its ability to resist deformation of the B-pillar and roof assembly, refer to Figure 1 and Figure 2 In some embodiments of this disclosure, the two first vertical bars 102 and the first horizontal bar 101 can be enclosed to form a gantry-shaped profile, and the first support frame 1 may also include a first reinforcing structure disposed on the inner side of the gantry-shaped profile.

[0041] This disclosure does not limit the first strengthening structure, for example in Figure 1 and Figure 2 In the illustrated embodiment, the first reinforcing structure may include a second horizontal bar 301 connected between the two first vertical bars 102 and two first diagonal bars 302. Each of the two first diagonal bars 302 may have one end connected to the bottom of the corresponding first vertical bar 102, and the other end extending obliquely upwards and connecting to the end of the first horizontal bar 101, so that the second horizontal bar 301 and the two first diagonal bars 302 intersect to form a radial force transmission path. This design, compared to the traditional triangular frame reinforcing structure with more redundant structures, optimizes the force transmission path, improves space utilization, eliminates redundant structures, and reduces overall weight. Furthermore, in some other embodiments, the first reinforcing structure may also include an additional first vertical bar to form a star-shaped force transmission structure.

[0042] This disclosure does not limit the cross connection method of the second horizontal bar 301 and the two first diagonal bars 302, for example, in Figure 2 In the illustrated embodiment, one of the first diagonal bars 302 can be a long bar welded between the first horizontal bar 101 and the first vertical bar 102, while the other first diagonal bar 302 includes two short bars. One short bar is welded at one end to the first vertical bar 102 and at the other end near the middle of the aforementioned long bar (first diagonal bar 302). The other short bar is welded at one end to the first horizontal bar 101 and at the other end near the middle of the aforementioned long bar (first diagonal bar 302). The second horizontal bar 301 also includes two short bars. One of them is welded at one end to the first vertical bar 102 and at the other end near the middle of the aforementioned long bar (first diagonal bar 302), while the other is welded at one end to the first vertical bar 102 and at the other end to the side wall of the short bar of the first diagonal bar 302 that includes two short bars. When welding the two bars, a weld joint can be first opened on the side wall of one of them, and then the end of the other bar can be aligned and installed to the weld joint and welded. In addition, in some other embodiments, the second crossbar 301 and the two first diagonal bars 302 may each include two short bars. In this case, a connector needs to be set in the middle of the gantry profile, and the six short bars are welded to the connector at one end to form a radial force transmission structure.

[0043] Reference Figure 1 and Figure 2 In some embodiments of this disclosure, a first reinforcing gusset 401 may be provided at the angle formed between the two first diagonal bars 302 and the first horizontal bar 101. Alternatively, a second reinforcing gusset 402 may be provided at the angle formed between the two first diagonal bars 302 and the second horizontal bar 301. Furthermore, in some embodiments, both the first reinforcing gusset 401 and the second reinforcing gusset 402 may coexist. Figure 2 In the illustrated embodiment, the second reinforcing gusset 402 can be positioned at the angle formed between the two first diagonal braces 302. Furthermore, in some other embodiments, the second reinforcing gusset 402 can also be positioned at the angle formed between a first diagonal brace 302 and a second crossbar 301; this disclosure does not impose any limitations on this. By providing the aforementioned reinforcing gussets, nodes subjected to high stress can be reinforced, effectively preventing collapse in the corresponding area during rollover, and enhancing the overall structural stability of the semi-cage roll cage. This disclosure does not limit the size of the first reinforcing gusset 401 and the second reinforcing gusset 402; they can be flexibly adjusted according to the load-bearing target of the roll cage.

[0044] When installing the aforementioned reinforcing angle brace, it is first necessary to fabricate it to match the shape of the included angle space between the two rods. Then, it is inserted into the corresponding included angle and welded to the corresponding rod to complete the installation. This disclosure does not limit the specific materials and structures of the aforementioned reinforcing angle brace. For example, in some embodiments, the reinforcing angle brace can be a fan-shaped hollow structure made of steel.

[0045] Furthermore, in order to ensure the stiffness of the aforementioned reinforced corner braces while also meeting the requirements of lightweight design, refer to Figure 1 and Figure 2 The first reinforcing corner brace 401 and the second reinforcing corner brace 402 may be provided with flanged holes 5. Alternatively, in some other embodiments, at least one of the first reinforcing corner brace 401 and the second reinforcing corner brace 402 may be provided with flanged holes 5.

[0046] Reference Figure 1 and Figure 2 In the embodiments disclosed herein, the bottom ends of the two first vertical rods 102 may each be provided with a first mounting seat 601, which is used for detachable connection with the base plate assembly. By designing the first mounting seat 601, a detachable connection with the vehicle body can be achieved, facilitating its installation and removal. Specifically, it can be connected to the base plate of the vehicle body, or it can be connected to the door sill of the vehicle body. The first mounting seat 601 can be welded to the first vertical rod 102.

[0047] This disclosure does not limit the structure of the first mounting base 601; for example, it can be constructed as a plate and have multiple threaded holes. By setting the first mounting base 601 to a universal structure, it is possible to connect with the door sills of different vehicle models without modifying the vehicle body structure.

[0048] Reference Figure 1 In some embodiments of this disclosure, an arc-shaped segment 1011 may be formed between the first horizontal bar 101 and the first vertical bar 102. By using the arc-shaped segment 1011 to transition and connect the bars in the two extending directions, the structural strength of the first support frame 1 can be improved, thereby enhancing its support capacity for the roof assembly and the B-pillar.

[0049] Reference Figure 1 and Figure 3 In some embodiments of this disclosure, the second support frame 2 may include two second vertical rods 201. The bottom ends of the two second vertical rods 201 may be connected to the base plate assembly, and the top ends of the two second vertical rods 201 may extend obliquely upward and be connected to the positions near the two ends of the first horizontal rod 101, thereby providing triangular support for the first support frame 1 and improving the deformation resistance of the semi-cage roll cage to the top cover assembly.

[0050] Reference Figure 3In some embodiments of this disclosure, to connect the second vertical rod 201 to the base plate assembly, the bottom ends of the two second vertical rods 201 can each be provided with a second mounting seat 602, which is used for detachable connection with the base plate assembly. This design allows for detachable connection between the second mounting seat 602 and the vehicle body, facilitating installation and removal. Specifically, the second mounting seat 602 can be connected to the rear longitudinal beam of the vehicle body, and its specific structure can be adapted to the actual structure of the rear longitudinal beam. The second mounting seat 602 and the second vertical rod 201 can be welded together. Furthermore, the second mounting seat 602 can also simultaneously provide mounting points for the vehicle's interior trim panels, resulting in higher integration; the structure of the second mounting seat 602 can be adapted to actual needs.

[0051] To enhance the structural strength of the second support frame 2, refer to Figure 3 In some embodiments of this disclosure, the second support frame 2 may further include a second reinforcing structure disposed between the two second vertical rods 201.

[0052] This disclosure does not limit the second strengthening structure; see reference. Figure 3 In some embodiments of this disclosure, the second reinforcing structure may include two second diagonal rods 7. Each second diagonal rod 7 may have one end connected to a corresponding second vertical rod 201 near its bottom, and the other end extending obliquely upwards and connecting to the other second vertical rod 201 near its top, so that the two second diagonal rods 7 can intersect to form an X-shaped force transmission path. This design, compared to the traditional triangular frame reinforcing structure with more redundant structures, optimizes the force transmission path, improves space utilization, eliminates redundant structures, and reduces overall weight. Furthermore, in other embodiments, the second reinforcing structure may also be configured in the same radial shape as the first reinforcing structure; this disclosure does not limit this.

[0053] This disclosure does not impose restrictions on the cross connection method of the two second diagonal bars 7, for example, in Figure 3 In the illustrated embodiment, one of the second diagonal rods 7 can be a long rod welded between the two second vertical rods 201, while the other second diagonal rod 7 comprises two short rods. One short rod is welded at one end to the second vertical rod 201 and at the other end near the middle of the aforementioned long rod (second diagonal rod 7), and the other short rod is welded at one end to the second vertical rod 201 and at the other end near the middle of the aforementioned long rod (second diagonal rod 7). When welding the two rods, a weld joint can be first opened on the side wall of one of them, and then the end of the other rod can be aligned and installed to the weld joint and welded. In addition, in some other embodiments, both second diagonal rods 7 may each comprise two short rods. In this case, a connector needs to be provided at the middle position of the two second vertical rods 201, and one end of each of the four short rods is welded to the connector to form an X-shaped force transmission structure.

[0054] Reference Figures 1-3 To connect the first support frame 1 and the second support frame 2, in some embodiments, the first support frame 1 may be provided with two joint struts 8, and the top ends of the two second vertical bars 201 may be respectively connected to the corresponding joint struts 8. The two joint struts 8 may be welded to the aforementioned arc-shaped segment 1011. Furthermore, in other embodiments, the second support frame 2 may also be directly welded to the first vertical bar 102 or the first horizontal bar 101 of the first support frame 1.

[0055] Furthermore, referring to Figure 2 and Figure 3 The top end of the second vertical rod 201 can form a first semi-cylindrical joint 901, and the end of the joint support rod 8 away from the first support frame 1 can form a second semi-cylindrical joint 902. The first semi-cylindrical joint 901 and the second semi-cylindrical joint 902 are connected to form a cylindrical segment 903 coaxial with the joint support rod 8. This design allows for a coaxial cylindrical segment 903 after the two semi-cylindrical joints are connected, thus creating a better force transmission path when the second support frame 2 supports the first support frame 1, improving the overall structural strength of the semi-cage roll cage. Furthermore, in some other embodiments, the joint support rod 8 and the second vertical rod 201 can be configured as a sleeved cylindrical shaft relationship, which is not a limitation of this disclosure.

[0056] Furthermore, in some embodiments of this disclosure, the first semi-cylindrical connector 901 may be provided with a plurality of first connecting holes 9011, and the second semi-cylindrical connector 902 may be provided with a plurality of second connecting holes 9021 opposite to the first connecting holes 9011. When it is necessary to connect the two, fasteners such as bolts are used to sequentially pass through the corresponding connecting holes to complete the connection. At the same time, when it is necessary to disassemble, the first support frame 1 and the second support 2 can be disassembled simply by removing the fasteners. In some embodiments of this disclosure, the lengths of the connector strut 8 and the second vertical rod 201 can be adjusted for adaptability, so that the first support frame 1 and the second support frame 2 can be disassembled and installed by entering and exiting the vehicle through the rear door opening, which is convenient for disassembly and installation, provides high flexibility for users, and has little impact on other parts of the vehicle (no disassembly required).

[0057] According to a second aspect of this disclosure, a vehicle is provided that includes the aforementioned semi-cage roll cage, the advantages of which will not be elaborated here.

[0058] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0059] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0060] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0061] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0062] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0063] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0064] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0065] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”
