Adapter structure, photovoltaic support and photovoltaic system

Abstract

This application relates to a transition structure, a photovoltaic bracket, and a photovoltaic system. The transition structure, used to connect a photovoltaic frame and a supporting structure, includes a first locking member, a second locking member, and a third locking member. The first locking member has a slot for engaging with the photovoltaic frame; the second locking member is connected to the photovoltaic frame; the third locking member is detachably connected to the second and first locking members, and forms a locking space with the first locking member to hold the supporting structure. The slot of the first locking member in the aforementioned transition structure can simultaneously engage with the top wall, bottom wall, and side wall of the frame. By adding a second locking member to the first and third locking members, the second locking member is connected to the frame and simultaneously to the first and third locking members. This allows the second locking member to simultaneously contact the top wall, bottom wall, and side wall of the frame, resulting in a more secure connection point under high wind loads. Under heavy wind loads, the transition structure will not slip due to cyclic loads, greatly improving the overall reliability of the structure.

Description

Technical Field

[0001] This application relates to the field of photovoltaic frame mounting technology, and in particular to a transition structure, photovoltaic bracket and photovoltaic system. Background Technology

[0002] Flexible photovoltaic (PV) brackets are a new type of PV installation structure that uses prestressed steel cables and connecting structures to form a tension system to support PV modules. Flexible PV brackets achieve large-span spatial layouts while maintaining structural rigidity, making them suitable for complex terrains (such as steep slopes, deep-water fishponds, and soft tidal flats) and special sites (such as sewage treatment plants).

[0003] In related technologies, the connection structure uses a combination of pressure blocks to fix the frame to the cable. However, the combination of pressure blocks is only snapped onto the bottom wall of the frame, making it difficult to position during installation. It cannot effectively prevent the pressure blocks from moving back and forth at the bottom of the frame, and slippage is likely to occur during operation. Under wind load, gaps are likely to occur, causing the components to collide back and forth with the pressure blocks, which can easily lead to fatigue failure of the connection points.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] Therefore, it is necessary to provide a transition structure, photovoltaic bracket and photovoltaic system to address the problem that the combined clamping block only contacts the bottom wall of the photovoltaic frame, which makes it difficult to position during installation, easily causes slippage, and easily leads to fatigue failure of the connection point.

[0006] Firstly, a switching structure includes:

[0007] A first locking component is provided with a slot for engaging with the photovoltaic frame.

[0008] A second locking element, the second locking element being connected to the photovoltaic frame; and

[0009] The third locking member is detachably connected to the second locking member and the first locking member, and forms a locking space with the first locking member to hold the support structure.

[0010] In one embodiment, the first locking member has a first mounting hole communicating with the slot, the second locking member has a second mounting hole, the third locking member has a third mounting hole, and the photovoltaic frame has a fourth mounting hole. The third locking member is detachably connected to the second locking member and the first locking member by fasteners passing through the first mounting hole, the second mounting hole, the third mounting hole and the fourth mounting hole simultaneously.

[0011] In one embodiment, the first locking member includes a main body and a bent portion, the bent portion being disposed on the main body to form the slot, and the main body having the first mounting hole extending through it.

[0012] In one embodiment, the fastener includes a bolt and a nut, the nut being located outside the second mounting hole, and the bolt being sequentially passed through the third mounting hole, the first mounting hole, the fourth mounting hole, and the second mounting hole before being connected to the nut.

[0013] In one embodiment, the first locking member is further provided with a locking groove, which is spaced apart on one side of the slot, and the locking groove and the third locking member form the locking space.

[0014] In one embodiment, the slot is provided on one side of the first locking member along a first direction and extends along a second direction to penetrate the opposite sides of the first locking member. The slot forms a first opening on one side of the first locking member along the first direction for the photovoltaic frame to be inserted.

[0015] The lock groove extends through the first lock member along the first direction, and second openings for the support structure to be inserted are formed on both opposite sides of the first lock member along the first direction, wherein the first direction intersects the second direction.

[0016] In one embodiment, reinforcing ribs are protruding from the groove wall of the card slot.

[0017] In a second aspect, a photovoltaic support structure includes the support structure and the transition structure as described in the first aspect.

[0018] Thirdly, a photovoltaic system includes:

[0019] A photovoltaic module, the photovoltaic module including a solar cell and the photovoltaic frame of the first aspect, the photovoltaic frame being used to support the solar cell;

[0020] A photovoltaic bracket, comprising a support structure as described in the first aspect and a connecting structure, the connecting structure being used to connect the photovoltaic frame to the support structure.

[0021] In one embodiment, the photovoltaic frame includes a top wall, a side wall, and a bottom wall. The top wall and the bottom wall are spaced apart from each other. The side wall is located between the top wall and the bottom wall. The top wall, the side wall, and the bottom wall are all located in the slot of the first locking member of the adapter structure. The second locking member is located between the top wall and the bottom wall and overlaps the bottom wall.

[0022] The first locking member of the aforementioned transition structure can simultaneously engage with the top, bottom, and side walls of the frame. A second locking member is added based on the first and third locking members. This second locking member connects to the frame and simultaneously to the first and third locking members, allowing it to simultaneously contact the top, bottom, and side walls of the frame. This results in a more robust connection point under high wind loads. The contact between the pressure block and the frame changes from a single-sided contact (only the bottom surface) to a multi-sided contact (like a clamp), ensuring even stress distribution and greater reliability at the connection points. Previously, the pressure block only contacted the frame on one side, making it difficult to position and install. The aforementioned transition structure directly wraps around the frame, making installation much easier. After installation, the transition structure forms a clamp-like connection with the frame, preventing slippage caused by cyclic loads under high wind loads, thus greatly improving the overall reliability of the structure.

Detailed Implementation

[0032] 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.

[0033] Flexible photovoltaic (PV) brackets are a new type of PV installation structure that uses prestressed steel cables and connecting structures to form a tension system to support PV modules. Flexible PV brackets achieve large-span spatial layouts while maintaining structural rigidity, making them suitable for complex terrains (such as steep slopes, deep-water fishponds, and soft tidal flats) and special sites (such as sewage treatment plants).

[0034] In related technologies, the connection structure used to connect the frame and the steel cable typically includes multiple clamping blocks. The first clamping block has a slot for engaging the bottom wall of the frame, and the second clamping block is located at the bottom of the first clamping block, securing the steel cable by engaging with a locking groove in the first clamping block. The first and second clamping blocks are connected by a bolt to clamp the bottom wall of the frame. Because the first and second clamping blocks only contact the bottom wall of the frame, this connection structure is difficult to position during installation and cannot effectively prevent the clamping blocks from moving back and forth at the bottom of the frame, making slippage likely during operation. Under wind loads, gaps can easily form, causing the components to collide with the clamping blocks, leading to fatigue failure at the connection point.

[0035] Based on the above issues, please refer to Figure 1This application provides a photovoltaic system 1000. The photovoltaic system 1000 includes a photovoltaic module 100 and a photovoltaic support 200. The photovoltaic module 100 includes a solar cell 10 and a photovoltaic frame 20, the photovoltaic frame 20 being used to support the solar cell 10. See also... Figure 2 and Figure 3 The photovoltaic bracket 200 includes a support structure 2 and a connecting structure 1, the connecting structure 1 being used to connect the photovoltaic frame 20 to the support structure 2.

[0036] For example, please refer to Figure 2 The supporting structure 2 can be a steel cable or a steel strand. A steel cable is a single steel wire with a large radial dimension, while a steel strand is made of multiple steel wires wound together.

[0037] Please see Figure 4 In some embodiments, the adapter structure 1 includes a first locking member 11, a second locking member 12, and a third locking member 13. The first locking member 11 is provided with a slot 111, please refer to [reference needed]. Figure 3 The slot 111 is used to engage with the photovoltaic frame 20. The second locking member 12 is connected to the photovoltaic frame 20. The third locking member 13 is detachably connected to the second locking member 12 and the first locking member 11, and forms a locking space 119 between the third locking member 13 and the first locking member 11 to hold the support structure 2. Please refer to... Figure 3 The slot 111 of the first locking member 11 of the aforementioned adapter structure 1 can simultaneously engage the top wall 201, bottom wall 203, and side wall 202 of the frame. A second locking member 12 is added based on the first locking member 11 and the third locking member 13. The second locking member 12 is connected to the photovoltaic frame 20, and simultaneously to the first locking member 11 and the third locking member 13. Thus, the second locking member 12 can simultaneously form contact with the top wall 201, bottom wall 203, and side wall 202 of the photovoltaic frame 20. Under high wind loads, the connection point is more robust, changing from the original single-sided contact with only the bottom wall 203 to a clamp-like multi-sided contact. The connection node experiences uniform force, making it more reliable. The aforementioned adapter structure 1 directly wraps around the photovoltaic frame 20, making installation easier. After installation, the adapter structure 1 forms a clamp-like connection with the photovoltaic frame 20. Under high wind loads, the adapter structure 1 will not slip due to periodic loads, greatly improving the overall reliability of the structure.

[0038] Please see Figure 3In some embodiments, the photovoltaic frame 20 includes a top wall 201, a side wall 202, and a bottom wall 203. The top wall 201 and the bottom wall 203 are spaced apart from each other, and the side wall 202 is located between the top wall 201 and the bottom wall 203. The top wall 201, the side wall 202, and the bottom wall 203 are all located within the slot 111 of the first locking member 11 of the adapter structure 1. The second locking member 12 is located between the top wall 201 and the bottom wall 203, and overlaps the bottom wall 203. By securing the top wall 201, the bottom wall 203, and the side wall 202 of the photovoltaic frame 20 within the slot 111, the contact area between the photovoltaic frame 20 and the first locking member 11 is increased, improving connection stability. The second locking member 12 overlapping the bottom wall 203 increases the contact points with the photovoltaic frame 20, making the connection between the adapter structure 1 and the photovoltaic frame 20 tighter and more stable. This design allows for better load distribution under external forces (such as wind and gravity), preventing localized stress concentration and improving the overall stability of the connection. Since the second locking member 12 contacts the bottom wall 203, it effectively limits the slippage of the transition structure 1 relative to the photovoltaic frame 20 under conditions of high wind loads. Compared to traditional connection structures that only contact one side of the frame's bottom wall 203, the overlapping of the second locking member 12 creates a clamp-like multi-sided contact, increasing the friction between the transition structure 1 and the photovoltaic frame 20, reducing slippage caused by periodic loads, and ensuring the reliability of the structure under complex working conditions. When the second locking member 12 overlaps on the bottom wall 203, the stress distribution on the transition structure 1 is more uniform. The top wall 201, side wall 202, and bottom wall 203 all contact the slot 111 of the first locking member 11, and the second locking member 12 overlaps with the bottom wall 203. This ensures that the stress on the entire connection node is no longer concentrated at a single point or surface, but is distributed across multiple locations. This uniform stress distribution can effectively reduce fatigue damage to various components and extend the service life of the photovoltaic bracket 200.

[0039] Please see Figure 3 In other optional embodiments, the photovoltaic frame 20 further includes a first support wall 204 and a second support wall 205. The first support wall 204 is disposed on the bottom wall 203 and is spaced apart from the side wall 202. The second support wall 205 is disposed on the first support wall 204 and is spaced apart from the top wall 201. The provision of the first support wall 204 and the second support wall 205 can improve the structural strength of the photovoltaic frame 20.

[0040] It should be noted that the photovoltaic frame 20 in this embodiment can also be other irregular structures, not limited to the configuration of a top wall 201, a bottom wall 203, and a side wall 202. Similarly, the slot 111 of the first locking member 11 in this embodiment is not limited to a square slot, but can also be an irregularly shaped slot adapted to other photovoltaic frames 20.

[0041] Please see Figure 4 Since the second locking member 12 overlaps the bottom wall 203 of the photovoltaic frame 20, and the second locking member 12 needs to be connected to both the first locking member 11 and the second locking member 12, the second locking member 12 is at least partially overlapped with the first locking member 11. In an optional embodiment, the second locking member 12 may be entirely located on the first locking member 11. Alternatively, a portion of the second locking member 12 may be located on the first locking member 11, and another portion may be located outside the first locking member 11.

[0042] Please see Figure 5 In some embodiments, the first locking member 11 has a first mounting hole 112 communicating with the slot 111, the second locking member 12 has a second mounting hole 121, the third locking member 13 has a third mounting hole 131, and the photovoltaic frame 20 has a fourth mounting hole 206 (see [reference]). Figure 3 The third locking member 13 is detachably connected to the second locking member 12 and the first locking member 11 by fasteners 14 passing through the first mounting hole 112, the second mounting hole 121, the third mounting hole 131, and the fourth mounting hole 206. The fasteners 14, passing through the first mounting hole 112, the second mounting hole 121, the third mounting hole 131, and the fourth mounting hole 206, tightly connect the first locking member 11, the second locking member 12, the third locking member 13, and the photovoltaic frame 20 together, forming a robust whole. Under external forces (such as wind or gravity), this connection method effectively prevents relative displacement between components, ensuring the structural stability of the photovoltaic system 1000 and reducing safety hazards caused by loose connections. The detachable connection of the third locking member 13 to the second locking member 12 and the first locking member 11 via fasteners 14 allows installers to easily assemble the components during the installation of the photovoltaic system 1000. During installation, simply snap the first locking member 11 onto the photovoltaic frame 20, align the second mounting hole 121 of the second locking member 12 with the fourth mounting hole 206 of the photovoltaic frame 20, and then assemble the third locking member 13 with the first locking member 11 to fix the support structure 2. Secure it by passing fasteners 14 through the corresponding mounting holes. This detachable connection method reduces installation difficulty and improves installation efficiency. Because the first locking member 11, the second locking member 12, the third locking member 13, and the photovoltaic frame 20 are connected together by fasteners 14, the force can be reasonably transmitted and distributed among these four components when subjected to external forces. The multi-faceted contact between the slot 111 of the first locking member 11 and the photovoltaic frame 20, the overlapping of the second locking member 12, and the locking action of the third locking member 13 together constitute a stable force-bearing system.

[0043] Please see Figure 5In some embodiments, the fastener 14 includes a bolt 141 and a nut 142. The nut 142 is located outside the second mounting hole 121. The bolt 141 passes through the third mounting hole 131, the first mounting hole 112, the fourth mounting hole 206, and the second mounting hole 121 in sequence before connecting to the nut 142. The nut 142 and bolt 141 provide a more stable connection between the first locking member 11, the second locking member 12, and the third locking member 13 and the photovoltaic frame 20. It is understood that the head of the bolt 141 abuts against the bottom of the third locking member 13, and the shank of the bolt 141 passes through the third mounting hole 131 of the third locking member 13, the first mounting hole 112 of the first locking member 11, the fourth mounting hole 206 of the bottom wall 203 of the photovoltaic frame 20, and the second mounting hole 121 of the second locking member 12 in sequence. The nut 142 is located at the top of the second locking member 12 and connects to the exposed threaded rod.

[0044] Please see Figure 5 In an optional embodiment, the fastener 14 further includes a washer 143, which is sleeved on the shank of the bolt 141 and abuts against the head of the bolt 141. The washer 143 is sandwiched between the head of the bolt 141 and the bottom surface of the third locking member 13.

[0045] The specific structure of the first locking element 11 will be described below:

[0046] Please see Figure 6 In some embodiments, the first locking member 11 includes a main body 113 and a bent portion 114. The bent portion 114 is disposed on the main body 113 to form a slot 111, and the main body 113 is provided with a first mounting hole 112. In other words, only the main body 113 of the first locking member 11 is connected to the second locking member 12 and the third locking member 13, and the bottom wall 203 of the photovoltaic frame 20 is provided with a fourth mounting hole 206. During installation, the fastener 14 passes through the third mounting hole 131 connecting the third locking member 13, the first mounting hole 112 on the main body 113, the fourth mounting hole 206 on the bottom wall 203, and the second mounting hole 121 of the second locking member 12 in sequence. The added bent portion 114 can increase the connection area between the first locking member 11 and the photovoltaic frame 20, so that the first locking member 11 can abut against the side wall 202 and the top wall 201 of the photovoltaic frame 20, thereby increasing the connection stability of the first locking member 11.

[0047] In other alternative embodiments, both the main body 113 and the bent portion 114 are provided with a first mounting hole 112. During installation, the fastener 14 passes sequentially through the third mounting hole 131 connecting the third locking member 13, the first mounting hole 112 on the main body 113, the fourth mounting hole 206 on the bottom wall 203, the second mounting hole 121 on the second locking member 12, and the first mounting hole 112 on the bent portion 114.

[0048] Please see Figure 6In some embodiments, reinforcing ribs 116 protrude from the groove wall of the slot 111. The reinforcing ribs 116 enable the slot 111 to form a wedge-shaped deformation and fasten after it is engaged with the photovoltaic frame 20, making the connection between the first locking member 11 and the photovoltaic frame 20 more reliable.

[0049] Please see Figure 6 Furthermore, the reinforcing rib 116 can be one or more, such as two, three, four, etc. When there are multiple reinforcing ribs 116, they can be along the first direction (e.g., Figure 6 The intervals are set in the AA direction (as shown), or along the second direction (such as...). Figure 6 The stiffeners are spaced apart in the BB direction (as shown), with the first and second directions intersecting. The distance between two adjacent stiffeners 116 can be the same or different.

[0050] Please see Figure 6 The slot 111 includes a first slot wall surface 111a, a second slot wall surface 111b, and a third slot wall surface 111c that are connected to each other. The second slot wall surface 111b is located between the first slot wall surface 111a and the third slot wall surface 111c. The first slot wall surface 111a and the third slot wall surface 111c are spaced apart, and the third slot wall surface 111c is the side closest to the third locking member 13. The reinforcing rib 116 can be provided on at least one of the first slot wall surface 111a, the second slot wall surface 111b, and the third slot wall surface 111c. For example, the reinforcing rib 116 is provided on the third slot wall surface 111c, or the reinforcing rib 116 is provided on both the first slot wall surface 111a and the third slot wall surface 111c. Taking the reinforcing rib 116 being provided on the third slot wall surface 111c as an example, the reinforcing rib 116 is set at an angle to the second slot wall surface 111b, for example, it can be set at a right angle or an acute angle. The embodiments of this application do not limit the cross-sectional shape of the reinforcing rib 116, for example, it can be square, parallelogram, trapezoid, dovetail or triangle, etc.

[0051] Please see Figure 6 In some embodiments, the first locking member 11 is further provided with a locking groove 115, which is spaced apart on one side of the slot 111, and a locking space 119 is formed between the locking groove 115 and the third locking member 13. The locking groove 115 allows the first locking member 11 to engage with the support structure 2. The locking groove 115 can be an arc-shaped groove or other shape that matches the radial cross-section of the support structure 2, which can increase the contact area between the first locking member 11 and the support structure 2 and improve the connection stability.

[0052] Please see Figure 6 The locking groove 115 and the slot 111 can be configured in several ways, but are not limited to: In one embodiment, the slot 111 is located on the first locking member 11 along a first direction (e.g., Figure 6 One side of the plane (as shown in direction AA), and along the second direction (as shown in direction AA). Figure 6The slot 111 extends along the first direction (as shown in BB direction) to both opposite sides of the first locking member 11. A first opening for the photovoltaic frame 20 to be inserted is formed on one side of the first locking member 11 along the first direction. A locking groove 115 extends along the first direction through the first locking member 11, and second openings for the support structure 2 to be inserted are formed on both opposite sides of the first locking member 11 along the first direction. In other words, the locking directions of the slot 111 for engaging the photovoltaic frame 20 and the locking groove 115 for engaging the support structure 2 are the same, facilitating engagement and improving the support effect of the support structure 2 on the photovoltaic frame 20.

[0053] In another embodiment, the slot 111 is provided on the first locking member 11 along a first direction (e.g., Figure 6 One side of the plane (as shown in direction AA), and along the second direction (as shown in direction AA). Figure 6 The locking groove 111 extends along the BB direction to penetrate the opposite sides of the first locking member 11. The locking groove 111 forms a first opening on one side of the first locking member 11 along the first direction for the photovoltaic frame 20 to be inserted. The locking groove 115 penetrates the first locking member 11 along the second direction and forms second openings on both opposite sides of the first locking member 11 along the second direction for the support structure 2 to be inserted. In other words, the locking directions of the locking groove 111 for engaging the photovoltaic frame 20 and the locking groove 115 for engaging the support structure 2 intersect.

[0054] Please see Figure 6 In an optional embodiment, the first locking member 11 has a through-hole 117, which communicates with the first mounting hole 112 and the third mounting hole 131. The mounting cavity 117 reduces the weight of the first locking member 11 and minimizes the impact of its own weight.

[0055] Please see Figure 5 and Figure 6 In an optional embodiment, the first locking member 11 is provided with a first hook portion 118, and the third locking member 13 is provided with a second hook portion 132. The first hook portion 118 and the second hook portion 132 engage to form a locking space 119, which can further improve the connection stability of the first locking member 11 and the third locking member 13. Along the second direction (e.g.) Figure 6 In the BB direction shown, the locking groove 115 is located between the first hook portion 118 and the mounting cavity 117.

[0056] Please see Figure 7 In an optional embodiment, the outer edge of the second locking member 12 is provided with an abutment portion 122, which is used to abut against the bottom wall 203 of the photovoltaic frame 20 (see [link]). Figure 3 ( ), used to limit the installation of the second locking member 12 and improve the connection stability of the second locking member 12.

[0057] Please see Figure 5The following describes in detail the usage method of a transition structure 1 in this application embodiment: After the slot 111 of the first locking member 11 is engaged with the photovoltaic frame 20, the first locking member 11 and the photovoltaic frame 20 are transferred to the support structure 2, so that the support structure 2 is located in the locking slot 115 of the first locking member 11. The second hook 132 of the third locking member 13 is engaged with the first hook 118 of the first locking member 11. The second locking member 12 is placed on the bottom wall 203 of the photovoltaic frame 20, so that the washer 143 in the fastener 14 is fitted onto the bolt 141. The shank of the bolt 141 passes through the third mounting hole 131 of the third locking member 13, the first mounting hole 112 on the main body 113 of the first locking member 11, the second mounting hole 121 on the bottom wall 203 of the photovoltaic frame 20, and the second mounting hole 121 of the second locking member 12, and is then fastened to the nut 142 of the fastener 14, thereby completing the installation of the transition structure 1.

[0058] 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.

[0061] 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.

[0062] 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.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
