Photovoltaic frame and photovoltaic module

Abstract

The application relates to a photovoltaic frame and a photovoltaic module. The photovoltaic frame comprises a main frame and an auxiliary frame. The main frame is provided with a mounting groove. The auxiliary frame is rotatably accommodated in the mounting groove, and the auxiliary frame is provided with a clamping groove. The clamping groove is used for clamping a laminated piece and is fixedly connected with the laminated piece through adhesive. In this way, the laminated piece is longitudinally constrained by the auxiliary frame, that is, the laminated piece is prevented from being pulled out of the clamping groove outwardly. In addition, the auxiliary frame and the laminated piece can rotate in the mounting groove, that is, the rotation constraint is released, thereby reducing the risk of module edge explosion caused by excessive constraint, and the height of the clamping groove is reduced without increasing the height of the clamping groove in the related art, which provides a design possibility space for the height reduction of the clamping groove. In addition, when the height of the clamping groove is reduced, the corresponding process adhesive amount is reduced, the cost is correspondingly reduced, and because the gap between the clamping groove and the laminated piece is reduced, the water vapor transmission rate is reduced, and the risk of reliability failure is reduced.

Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic frame and a photovoltaic module. Background Technology

[0002] With the continuous development of photovoltaic technology, photovoltaic modules, which are semiconductor devices that convert solar energy into electrical energy, have been rapidly developed. A photovoltaic module consists of a laminate (from top to bottom: glass, encapsulation layer, cell layer, encapsulation layer, and backsheet or glass), a photovoltaic frame (usually made of aluminum alloy), and a junction box. The photovoltaic frame primarily enhances the photovoltaic module's resistance to mechanical loads, facilitating installation onto photovoltaic mounting structures. It also protects the four sides of the laminate from external impacts that could cause breakage, and seals the four sides of the laminate to prevent moisture infiltration that could affect module performance and reliability.

[0003] In related technologies, photovoltaic (PV) frames are equipped with slots into which laminates are inserted and fixed to the inner wall of the slots using adhesive. When PV modules are mounted using a pressure block method, the strong constraint of the pressure block on the PV frame causes stress concentration on the laminate near the pressure block, resulting in a significant risk of component failure due to bursting. To mitigate the risk of laminate bursting in PV frame mounting, methods such as increasing the slot height, fine-tuning the surface curvature of the slot's inner cavity, and increasing the amount of adhesive within the slot are commonly employed.

[0004] All of the above solutions increase adhesive consumption, leading to higher costs and potentially causing adhesive overflow and poor appearance. Furthermore, increasing the slot height inevitably increases the contact area between the adhesive and air, resulting in reliability defects in the photovoltaic module due to increased water vapor transmission. Additionally, it increases the probability of laminated components detaching from the frame and failing. Summary of the Invention

[0005] Therefore, it is necessary to overcome the shortcomings of existing technologies and provide a photovoltaic frame and photovoltaic module that can ensure a large adhesive force to the laminate, reduce the probability of frame failure, reduce the gap between the photovoltaic frame and the laminate, reduce water vapor transmission rate, reduce cost, and reduce the risk of component failure.

[0006] A photovoltaic frame, the photovoltaic frame comprising:

[0007] The main frame has a mounting groove; and an auxiliary frame is rotatably housed in the mounting groove. The auxiliary frame has a slot, the inner wall of which is provided with adhesive and used to fasten and fix the laminate.

[0008] In one embodiment, the inner wall of the mounting groove and / or the outer wall of the auxiliary frame are provided with a rotation limiting part for limiting the rotation angle of the auxiliary frame.

[0009] In one embodiment, the initial position is defined as the position where the slot opening is parallel to the surface of the laminate, and the auxiliary frame can rotate clockwise and / or counterclockwise around its central axis based on the initial position.

[0010] In one embodiment, the auxiliary frame rotates clockwise around its central axis from the initial position by a first set angle, the first set angle being 1° to 30°; and / or, the auxiliary frame rotates counterclockwise around its central axis from the initial position by a second set angle, the second set angle being 1° to 30°.

[0011] In one embodiment, the inner wall of the mounting groove includes a first arc-shaped wall, and the outer wall of the auxiliary frame includes a second arc-shaped wall, the second arc-shaped wall being adapted to the first arc-shaped wall.

[0012] In one embodiment, the rotation limiting part includes a first limiting part disposed on the inner wall of the mounting groove and a second limiting part disposed on the outer wall of the auxiliary frame; the first limiting part is connected to the first arc-shaped wall, and the second limiting part is connected to the second arc-shaped wall; when the auxiliary frame is in the initial position, the first limiting part and the second limiting part are disposed at a distance from each other; when the auxiliary frame rotates clockwise from the initial position to the point where the first limiting part and the second limiting part abut against each other, the mounting groove limits the clockwise rotation of the auxiliary frame; when the auxiliary frame rotates counterclockwise from the initial position to the point where the first limiting part and the second limiting part abut against each other, the mounting groove limits the counterclockwise rotation of the auxiliary frame.

[0013] In one embodiment, the first limiting part is a flat wall parallel to the orientation of the card slot opening, and the second limiting part is a flat wall parallel to the orientation of the card slot opening; the first limiting part is located at the top of the auxiliary frame, and the second limiting part is located at the top of the auxiliary frame.

[0014] In one embodiment, the rotation limiting part includes a first limiting member disposed on the outer wall of the auxiliary frame and a second limiting member disposed on the inner wall of the mounting groove. The first limiting member and the second limiting member abut against each other, and the first limiting member and / or the second limiting member are elastic members.

[0015] In one embodiment, the outer wall of the auxiliary frame is provided with a guide groove, the first limiting member is embedded in the guide groove, the first limiting member has a limiting hole on the wall surface facing the second limiting member, and the second limiting member is inserted into the limiting hole.

[0016] In one embodiment, when the slot opening is parallel to the surface of the laminate, the first limiting member facing away from the guide groove fits against the inner wall of the mounting groove.

[0017] In one embodiment, there are multiple first limiting members, and all the first limiting members are arranged sequentially at intervals along the extension direction of the guide groove.

[0018] A photovoltaic module includes the aforementioned photovoltaic frame and a laminate connected to the photovoltaic frame.

[0019] The aforementioned photovoltaic frame and photovoltaic module feature a rotatable auxiliary frame within the mounting groove of the main frame. Adhesive is provided in the slot, and the laminate is installed into the slot and fixedly connected to it via adhesive. This provides longitudinal constraint on the laminate through the auxiliary frame, preventing it from detaching outwards through the slot. Furthermore, the auxiliary frame, along with the laminate, can rotate within the mounting groove, releasing rotational constraints and reducing the risk of module edge breakage due to excessive constraint. Unlike related technologies, this eliminates the need to increase the slot height to release rotational constraints, allowing for a reduction in slot height. Additionally, a lower slot height reduces the amount of adhesive applied during manufacturing, lowering costs. The reduced gap between the slot and the laminate also decreases moisture permeability, further reducing the risk of reliability failure. Attached Figure Description

Adhesive. Detailed Implementation

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] As described in the background section, existing photovoltaic frames suffer from drawbacks such as high cost due to excessive adhesive consumption, adhesive overflow, and high water vapor permeability. Furthermore, the probability of laminated components detaching from the frame is also relatively high. The inventors' research revealed that this problem arises because, to improve the photovoltaic frame's ability to prevent laminated components from detaching, the rotational constraint on the laminated components needs to be reduced, which necessitates increasing the height of the mounting slot. However, increasing the slot height results in a larger amount of adhesive being stored inside the slot.

[0030] Based on the above reasons, the present invention provides a photovoltaic frame and a photovoltaic module that can ensure a large adhesive force to the laminate, reduce the probability of frame detachment failure, and at the same time reduce the gap between the photovoltaic frame and the laminate, reduce water vapor transmission rate, reduce cost, and reduce the risk of component failure.

[0031] See Figures 1 to 3 , Figure 1 A schematic diagram of the structure of a photovoltaic frame according to an embodiment of this application is shown. Figure 2 It shows Figure 1 A magnified structural diagram at point A. Figure 3 This illustration shows a schematic diagram of a laminate 30 installed in a photovoltaic frame according to an embodiment of this application. An embodiment of this application provides a photovoltaic frame comprising a main frame 10 and an auxiliary frame 20. The main frame 10 has a mounting groove 11. The auxiliary frame 20 is rotatably housed in the mounting groove 11 and has a locking slot 21. The locking slot 21 is used to engage and fix the laminate 30, and is fixedly connected to the laminate 30 by adhesive 40.

[0032] The aforementioned photovoltaic frame features a rotatable auxiliary frame 20 within the mounting groove 11 of the main frame 10, and adhesive 40 within the slot 21. The laminate 30 is installed in the slot 21 and fixedly connected to it via the adhesive 40. This design achieves longitudinal constraint on the laminate 30 through the auxiliary frame 20, preventing it from detaching outwards through the slot 21. Furthermore, the auxiliary frame 20, along with the laminate 30, can rotate within the mounting groove 11, releasing rotational constraints and reducing the risk of component breakage due to excessive constraint at the module edge. Unlike related technologies, this design eliminates the need to increase the height of the slot 21 to release rotational constraints, allowing for a reduction in the slot 21's height. Additionally, a lower slot 21 requires less adhesive, reducing costs. The reduced gap between the slot 21 and the laminate 30 also decreases water vapor transmission, further mitigating the risk of reliability failure.

[0033] It should be noted that, in this embodiment, "vertical" refers to... Figure 2 As shown by the Z-axis. Furthermore, the rotation direction of the auxiliary frame 20 within the mounting slot 11 is as follows: Figure 3 As indicated by arrow F in the diagram. Additionally, the height of slot 21 is also the distance between the slot opening and the two side walls, as shown in the diagram. Figure 2 As shown in H in the diagram.

[0034] Please see Figure 6 and Figure 7 , Figure 6 A structural view of the auxiliary frame 20 in a photovoltaic frame according to an embodiment of this application is shown. Figure 7 This illustration shows another structural view of the auxiliary frame 20 in a photovoltaic frame according to an embodiment of this application. In one embodiment, the inner wall shape of the slot 21 can be the same as that of the slot 21 in the photovoltaic frame of the related art, so as to achieve high compatibility with the process equipment of the conventional frame; or it can be different from the inner wall shape of the slot 21 in the photovoltaic frame of the related art, which can be flexibly adjusted and set according to actual needs.

[0035] Please see Figure 6 and Figure 7 In one embodiment, at least one overflow groove 211 is formed on the inner wall of the slot 21. The specific number, position, and shape of the overflow grooves 211 can be flexibly adjusted and set according to actual needs. In this embodiment, the overflow groove 211 is specifically arranged, for example, on one side of the inner wall forming the opening of the slot 21. Thus, during the assembly process, after the laminate 30 is inserted into the slot 21, the adhesive 40 inside the slot 21 can be squeezed into the overflow groove 211, preventing the adhesive 40 from overflowing outward through the slot 21.

[0036] Please see Figures 2 to 5, Figure 4 A structural diagram showing the auxiliary frame 20 in a photovoltaic frame according to an embodiment of this application is shown, in which the auxiliary frame 20 rotates clockwise. Figure 5 A structural diagram showing the counterclockwise rotation of an auxiliary frame 20 in a photovoltaic frame according to an embodiment of this application is illustrated. In one embodiment, a rotation limiting part is provided on the inner wall of the mounting groove 11 and / or the outer wall of the auxiliary frame 20 to limit the rotation angle of the auxiliary frame 20. Thus, the rotation of the auxiliary frame 20 is limited by the rotation limiting part, allowing control of the rotation angle of the auxiliary frame 20 within the mounting groove 11. This satisfies the requirement that the auxiliary frame 20 rotates within the mounting groove 11 to release rotational constraints and reduce the risk of component explosion, while also preventing excessive rotation angle of the laminate 30 from causing microcracks. Furthermore, since the auxiliary frame 20 rotates within a preset angle range, the rotational stability of the auxiliary frame 20 is improved, and defects such as detachment from the mounting groove 11 due to excessive rotation angle are avoided.

[0037] Please see Figures 2 to 5 In one embodiment, the initial position is defined as the position where the slot opening of the card slot 21 is parallel to the surface of the laminate 30 (e.g., ...). Figure 2 as well as Figure 3 As shown), the auxiliary frame 20 can rotate clockwise around its central axis from its initial position. Thus, when the opening of the slot 21 is parallel to the surface of the laminate 30, the laminate 30 does not rotate, and the auxiliary frame 20 remains in its initial position (as shown). Figure 2 as well as Figure 3 As shown); when the laminate 30 rotates clockwise (as shown) Figure 4 As shown in the figure, since the auxiliary frame 20 can rotate clockwise from its initial position, the rotation constraint can be released, reducing the risk of the parts breaking.

[0038] Please see Figures 2 to 5 In another embodiment, the initial position is set when the slot opening of the card slot 21 is parallel to the surface of the laminate 30 (e.g., ...). Figure 2 as well as Figure 3 As shown), the auxiliary frame 20 can rotate counterclockwise around its central axis from its initial position. Thus, when the opening of the slot 21 is parallel to the surface of the laminate 30, the laminate 30 does not rotate, and the auxiliary frame 20 remains in its initial position (as shown). Figure 2 as well as Figure 3 (as shown); when the laminate 30 rotates counterclockwise (e.g.) Figure 5 As shown in the figure, since the auxiliary frame 20 can rotate counterclockwise from its initial position, the rotation constraint can also be released, reducing the risk of parts breaking.

[0039] Please see Figures 2 to 5 In one specific embodiment, the initial position is set when the opening of the slot 21 is parallel to the surface of the laminate 30 (e.g., ...). Figure 2 as well as Figure 3 As shown, the auxiliary frame 20 can rotate clockwise and counterclockwise around its central axis from its initial position. Thus, since both clockwise and counterclockwise rotation of the auxiliary frame 20 are restricted, its left and right rotation is limited to a preset angle range, improving its rotational stability and preventing it from detaching from the mounting slot 11 due to excessive rotation angle.

[0040] It should be noted that the orientation of the slot 21 is as follows: Figure 2 or Figure 3 As shown on the Z-axis.

[0041] Please see Figures 2 to 5 In one embodiment, the auxiliary frame 20 is rotated clockwise around its central axis from its initial position by a first predetermined angle. Optionally, the first predetermined angle includes, but is not limited to, 1° to 30°.

[0042] Specifically, the first set angle includes, but is not limited to, 1°, 5°, 10°, 15°, 30°, or any value from 1° to 30° as needed.

[0043] Please see Figures 2 to 5 In one embodiment, the auxiliary frame 20 is rotated counterclockwise around its central axis from its initial position by a second predetermined angle. Optionally, the second predetermined angle includes, but is not limited to, 1° to 30°.

[0044] Specifically, the second set angle includes, but is not limited to, 1°, 5°, 10°, 15°, 30°, or any value from 1° to 30° as needed.

[0045] Please see Figures 2 to 5 In one embodiment, the inner wall of the mounting groove 11 includes a first arcuate wall 111. The outer wall of the auxiliary frame 20 includes a second arcuate wall 22. The second arcuate wall 22 is adapted to the first arcuate wall 111. Thus, when the auxiliary frame 20 rotates within the main frame 10, the second arcuate wall 22 rotates along the first arcuate wall 111, resulting in good rotational stability.

[0046] Please see Figures 2 to 5Specifically, the auxiliary frame 20 includes a base plate 23, a side plate 24, and a top plate 25. The opposite ends of the side plate 24 are connected to the base plate 23 and the top plate 25, respectively, and the base plate 23, the side plate 24, and the top plate 25 together form a slot 21. The second arc-shaped wall 22 is provided, for example, on one end of the base plate 23 away from the side plate 24, and on one end of the top plate 25 away from the side plate 24. The second arc-shaped wall 22 is provided at multiple locations at the connection points between the base plate 23 and the side plate 24, and at the connection points between the top plate 25 and the side plate 24. These locations abut against and cooperate with the first arc-shaped wall 111 to achieve stable rotation of the auxiliary frame 20 within the mounting slot 11.

[0047] Please see Figures 2 to 5 In one embodiment, the rotation limiting part includes a first limiting part 112 disposed on the inner wall of the mounting groove 11 and a second limiting part 26 disposed on the outer wall of the auxiliary frame 20. The first limiting part 112 is connected to the first arcuate wall 111, and the second limiting part 26 is connected to the second arcuate wall 22. When the auxiliary frame 20 is in the initial position, the first limiting part 112 and the second limiting part 26 are spaced apart from each other. When the auxiliary frame 20 rotates clockwise from the initial position until the first limiting part 112 and the second limiting part 26 abut against each other, the mounting groove 11 limits the clockwise rotation of the auxiliary frame 20; when the auxiliary frame 20 rotates counterclockwise from the initial position until the first limiting part 112 and the second limiting part 26 abut against each other, the mounting groove 11 limits the counterclockwise rotation of the auxiliary frame 20.

[0048] Please see Figures 2 to 5 In one embodiment, the first limiting part 112 is a flat wall parallel to the opening of the slot 21, and the second limiting part 26 is a flat wall parallel to the opening of the slot 21. The first limiting part 112 is located at the top of the auxiliary frame 20, and the second limiting part 26 is located at the top of the auxiliary frame 20. In this way, on the one hand, compared with setting the top of the main frame 10 as an arc-shaped wall, it can not only limit rotation, but also ensure that the top thickness of the main frame 10 is large enough to ensure sufficient strength; on the other hand, it can reduce the distance between the top surface of the main frame 10 and the laminate 30, thereby reducing the defect of dust accumulation on the top of the main frame 10.

[0049] Of course, in some alternative solutions, the first limiting part 112 and the second limiting part 26 are not limited to the straight wall in the above embodiment. They can also be flexibly adjusted and set to other shapes according to actual needs, including but not limited to regular shapes such as wavy lines, broken lines, or other irregular shapes, as long as they are not set as arc-shaped walls.

[0050] Please see Figures 2 to 5In one embodiment, the rotation limiting part includes a first limiting member 27 disposed on the outer wall of the auxiliary frame 20 and a second limiting member 113 disposed on the inner wall of the mounting groove 11. The first limiting member 27 and the second limiting member 113 abut against each other, and the first limiting member 27 and / or the second limiting member 113 are elastic members. Thus, when the auxiliary frame 20 rotates under the drive of the laminate 30, the elastic members are simultaneously deformed, and the elastic members play a buffering role, which is also conducive to driving the auxiliary frame 20 and the laminate 30 to return to their original positions.

[0051] Optionally, the elastic element includes, but is not limited to, elastic strips, elastic blocks, elastic rods, springs, etc. Its specific material can be either metal or non-metal; non-metallic materials include, for example, rubber, resin, or sponge.

[0052] Please see Figure 2 , Figure 6 and Figure 7 In one embodiment, the outer wall of the auxiliary frame 20 is provided with a guide groove 28, the first limiting member 27 is embedded in the guide groove 28, the first limiting member 27 is provided with a limiting hole 271 on the wall surface facing the second limiting member 113, and the second limiting member 113 is inserted into the limiting hole 271.

[0053] Please see Figure 2 and Figure 3 In one embodiment, when the opening of the slot 21 is parallel to the surface of the laminate 30, that is, when the slot 21 is in a horizontal state (e.g. Figure 2 or Figure 3 As shown, the wall of the first limiting member 27 facing away from the guide groove 28 is in contact with the inner wall of the mounting groove 11. In this way, the contact state between the first limiting member 27 and the inner wall of the mounting groove 11 can ensure that the slot opening of the card slot 21 is horizontal during the frame assembly process, so that the laminate 30 can smoothly enter the card slot 21.

[0054] In one embodiment, the first limiting member 27 is provided with a flat surface, an arc surface, or other shapes on the wall surface opposite to the guide groove 28.

[0055] Please see Figure 2 , Figure 6 and Figure 7 In one embodiment, multiple first limiting members 27 are provided, and all first limiting members 27 are arranged sequentially at intervals along the extension direction of the guide groove 28. In this way, it is not necessary to set the first limiting members 27 as a single piece, but to set multiple members and arrange them at intervals in the guide groove 28, which can reduce the amount of material used and thus reduce costs.

[0056] It should be noted that the extension direction of the guide groove 28 is also the length direction of the guide groove 28, such as... Figure 1 or Figure 7 As indicated by arrow L in the diagram.

[0057] Specifically, multiple first limiting members 27 are arranged in the guide groove 28 at equal or unequal intervals.

[0058] As an alternative, the number of first limiting members 27 can be set to one and placed in the guide groove 28.

[0059] Please see Figures 1 to 3 In one embodiment, a photovoltaic module includes a photovoltaic frame of any of the above embodiments and a laminate 30 connected to the photovoltaic frame.

[0060] The aforementioned photovoltaic module features a rotatable auxiliary frame 20 within the mounting groove 11 of the main frame 10, and adhesive 40 within the slot 21. The laminate 30 is installed in the slot 21 and fixedly connected to it via the adhesive 40. This design achieves longitudinal constraint on the laminate 30 through the auxiliary frame 20, preventing it from detaching outwards through the slot 21. Furthermore, the auxiliary frame 20, along with the laminate 30, can rotate within the mounting groove 11, releasing rotational constraints and reducing the risk of module edge breakage due to excessive constraint. Unlike related technologies, this design eliminates the need to increase the height of the slot 21 to release rotational constraints, allowing for a reduction in the slot 21's height. Additionally, a lower slot 21 requires less adhesive, reducing costs. The reduced gap between the slot 21 and the laminate 30 also decreases water vapor transmission, further mitigating the risk of reliability failure.

[0061] It should be noted that the laminate 30 in this embodiment includes glass, encapsulation layer, battery layer, encapsulation layer and backplate or glass arranged sequentially from top to bottom.

[0062] Optionally, the photovoltaic module can be a single-glass photovoltaic module or a double-glass photovoltaic module. For double-glass photovoltaic modules, both the top and bottom layers of the laminate 30 are made of glass, for example, resulting in better light transmission, higher power generation efficiency, and better wear resistance. This makes them suitable for photovoltaic power stations in residential areas, coastal areas, chemical plants, and areas with high acid rain or salt spray. For single-glass photovoltaic modules, only the top layer of the laminate 30 is made of glass, while the bottom layer can be made of materials such as polyvinyl fluoride composite film or thermoplastic elastomer. This facilitates installation and reduces losses during transportation, making them suitable for industrial applications.

[0063] In one embodiment, the adhesive 40 in this embodiment includes, but is not limited to, silicone, polyurethane, polystyrene, polyacrylate, ethylene vinyl acetate copolymer, etc., which can be flexibly selected according to actual needs.

[0064] It should be noted that the "second limiting member 113" can be a part of the "main body frame 10", that is, the "second limiting member 113" and the "other parts of the main body frame 10" are integrally formed; or it can be an independent component that can be separated from the "other parts of the main body frame 10", that is, the "second limiting member 113" can be manufactured independently and then combined with the "other parts of the main body frame 10" to form a whole.

[0065] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; 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 in this application based on the specific circumstances.

[0068] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0069] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
