Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic panel fixing technology, and more particularly to photovoltaic panel brackets and photovoltaic panel modules. Background Technology
[0002] With the advancement of photovoltaic power generation technology, the application scope of photovoltaic power generation is becoming increasingly widespread, and residential photovoltaic power generation is developing rapidly. However, current photovoltaic power generation has certain limitations; it can only be installed on the sloping roofs of villas or the flat roofs of bungalows. For high-rise buildings, its installation utilization rate is relatively low.
[0003] Currently, there are photovoltaic panel brackets available on the market for installation on balconies. These brackets allow for adjustment of the photovoltaic panel's angle, ensuring its power generation efficiency. However, because the top of the photovoltaic panel is close to the balcony, the upper part of the panel is easily blocked by protruding objects above or placed in the shadow above, resulting in an actual power generation that is still not ideal. Utility Model Content
[0004] The purpose of this application is to address the problem in existing technologies where photovoltaic panels are easily shaded, resulting in lower actual power generation. Therefore, this application provides a photovoltaic panel support frame and a photovoltaic panel module. By changing the traditional three-link main structure to a four-link main structure, the top of the photovoltaic panel can be moved away from the mounting surface, thereby reducing shading and increasing the actual power generation of the photovoltaic panel. Furthermore, the stability and reliability of the support frame are enhanced by the fixing rods, and the four-link module is foldable, with variable connection states between the fixing rods and the four-link module, facilitating the overall folding of the support frame for easy transportation and storage.
[0005] This application provides a photovoltaic panel support, including at least two four-bar linkages and corresponding fixing rods that support and fix the four-bar linkages;
[0006] The at least two four-bar linkages are used to mount the photovoltaic panel, such that the photovoltaic panel is positioned at a first angle. The four-bar linkages are foldable and include:
[0007] Backrest, used for fixing to the external mounting surface;
[0008] Mounting rods are used to install photovoltaic panels;
[0009] A support rod connects the back rod and the mounting rod, and the mounting rod is inclined at the first angle relative to the back rod;
[0010] An extension rod is disposed away from the support rod and connects the end of the back rod and the end of the mounting rod. When the bracket is in the extended state, the top of the mounting rod has a first distance from the back rod in a first direction, the first direction being perpendicular to the mounting surface.
[0011] The two ends of the fixing rod are respectively connected to the support rod and the mounting rod, and the fixing rod is slidably connected to or detachably connected to one of the support rod and the mounting rod.
[0012] By adopting the above technical solution, the extension rod set between the back pole and the mounting rod pushes the mounting rod away from the back pole by a certain distance. This pushes the photovoltaic panel mounted on the mounting rod away from the mounting surface of the fixed back pole by a first gap, that is, pushes the photovoltaic panel outward away from the mounting surface. This allows the photovoltaic panel, especially the top of the photovoltaic panel, to be away from the shading area above the mounting surface, so as to fully receive solar energy and improve the actual power generation (output power) of the photovoltaic panel. At the same time, it can also avoid the hot spot effect and ensure the life of the photovoltaic panel. Furthermore, the fixed rod improves the stability and reliability of the four-bar linkage assembly including the extension rod, thereby improving the stability and reliability of the bracket and ensuring the safety of the photovoltaic panel.
[0013] By placing the fixing rod between the support rod and the mounting rod, the stability and reliability of the four-bar linkage are improved; furthermore, the sliding or detachable ends of the fixing rod and the foldable nature of the four-bar linkage allow the entire bracket to be folded, facilitating transportation and storage.
[0014] In some embodiments, the two ends of the support rod are respectively connected to the ends of the back rod away from the extension rod and the middle part of the mounting rod;
[0015] The four connection endpoints of the four-bar linkage are a first end, a second end, a third end, and a fourth end, wherein the first end is located between the back bar and the extension bar, the second end is located between the extension bar and the mounting bar, the third end is located between the mounting bar and the support bar, and the fourth end is located between the support bar and the back bar.
[0016] The first end, the second end, the third end, and the fourth end are rotatable connection points during the unfolding and folding of the bracket. During the folding process, the extension rod and the mounting rod fold relative to each other around the second end, and the back rod and the support rod fold relative to each other around the fourth end.
[0017] The distance between the first end and the second end is a, the distance between the second end and the third end is b, the distance between the third end and the fourth end is c, and the distance between the fourth end and the first end is d, and b+c=a+d, a<b.
[0018] By adopting the above technical solution, and through the design of the various connection endpoints and spacing of the four-bar linkage, the back bar, extension bar, mounting bar, and support bar of the four-bar linkage can be brought as close as possible when the four-bar linkage is folded, thereby controlling the volume of the folded bracket and making it easier to transport and store. Furthermore, the four-bar linkage can maintain the connection state of each bar when folded and unfolded, thereby reducing isolated parts, further improving the portability of transportation and storage, and also making it easier for users to fold, store, unfold, and use.
[0019] In some embodiments, both the extension rod and the support rod include two symmetrically arranged first clamping portions, which are located on both sides of the corresponding connection endpoints. When the bracket is folded, the mounting rod and the back rod are in an overlapping or stacked state.
[0020] By adopting the above technical solution, the extension rod and support rod are designed to be clamped on both sides of the connection end, so that when the bracket is folded, the back rod, extension rod, mounting rod and support rod can be brought closer together, thereby further reducing the folded volume and making the folded bracket more regular in shape, thus further facilitating transportation and storage.
[0021] In some embodiments, both the mounting rod and the back rod have U-shaped cross-sections, and their openings face each other.
[0022] The four connection endpoints of the four-bar linkage are formed by drilling holes and setting fasteners on the side walls of the U-shaped grooves corresponding to the mounting rod and the back rod, respectively.
[0023] The mounting rod is provided with a first clearance opening corresponding to the first end to avoid the fastener at the first end, and the back rod is provided with a second clearance opening corresponding to the third end to avoid the fastener at the third end; and the mounting rod and the back rod are in an overlapping state when the bracket is folded.
[0024] In some embodiments, the back bar corresponding to the first end and the fourth end, and the mounting rod corresponding to the second end and the third end, are all fixed with relatively protruding connecting blocks;
[0025] The connecting block includes two symmetrically arranged second clamping parts, which are respectively connected to the corresponding two first clamping parts to form the connecting endpoints; and such that when the bracket is folded, the fixing rod is nested in the two first clamping parts of the support rod and the corresponding second clamping parts of the connecting block, and the mounting rod and the back rod are stacked through the connecting block.
[0026] In some embodiments, the extension rod and the support rod have U-shaped cross-sections, and the two side walls of the U-shaped groove are respectively the two first clamping portions; or,
[0027] The extension rod and the support rod include two clamping plates arranged symmetrically, and the two clamping plates are respectively the two first clamping parts.
[0028] In some embodiments, the two ends of the fixing rod are respectively connected to the support rod and the mounting rod, and the end of the mounting rod away from the extension rod is close to the extension rod, such that the mounting rod sequentially connects the extension rod, the support rod and the fixing rod along its length direction, and the mounting rod, the fixing rod and the support rod form a triangular structure located outside the four-bar linkage assembly.
[0029] By adopting the above technical solution, the stability and reliability of the four-bar linkage are further improved by placing the fixing rod between the support rod and the mounting rod, and located outside the four-bar linkage assembly, forming a triangular support on the outside of the four-bar linkage assembly. Furthermore, the three-point support formed by the extension rod, support rod, and fixing rod along the length of the mounting rod can better distribute the gravity of the photovoltaic panel on the mounting rod, further improving the stability and reliability of the bracket, thereby further ensuring the installation stability and reliability of the photovoltaic panel.
[0030] In some embodiments, the support rod is connected to one-third of the mounting rod and is close to the extension rod;
[0031] One end of the fixing rod is connected to the middle of the support rod, and the other end is connected between the end of the support rod and the end of the mounting rod away from the extension rod.
[0032] In some embodiments, the fixing rod and the mounting rod are slidably connected, and during the folding of the bracket, the fixing rod slides along the mounting rod, thereby enabling the bracket to be folded; or,
[0033] The fixing rod and the support rod are detachably connected, and during the folding process of the bracket, the fixing rod and the support rod are in a detached and separated state, so that the bracket can be folded.
[0034] In some embodiments, the mounting rod is provided with a plurality of fixing holes, and the fixing rod is engaged with any of the fixing holes by a snap-fit member to adjust the first angle and to be locked and fixed by a locking member.
[0035] In some embodiments, the mounting rod is provided with a sliding groove, and the fixing rod is slidably connected to the sliding groove via a slider to adjust the first angle and lock it in place.
[0036] In some embodiments, there is a gap between the two first clamping portions of the fixing rod and the support rod, such that when the fixing rod and the support rod are locked, the support rod elastically deforms and forms an elastic fastening force on the third end, the fourth end and the connection between the fixing rod and the support rod.
[0037] This application also provides a photovoltaic panel assembly, including any of the brackets described above, and a photovoltaic panel;
[0038] The mounting rod of the bracket is fixed with a stop bar and a drag plate. The stop bar is located near the extension rod, and the drag plate is located at the end of the mounting rod away from the extension rod. The top of the frame of the photovoltaic panel is connected to the stop bar, and the bottom of the frame of the photovoltaic panel is supported by the drag plate; or...
[0039] The mounting rod of the bracket is nested inside the frame of the photovoltaic panel, and its two ends are fixed to the top and bottom of the frame of the photovoltaic panel, respectively.
[0040] By employing the above technical solution, the photovoltaic panels are reliably and stably pushed away from the mounting surface by the extension rods and fixing rods of the bracket. This allows the photovoltaic panels, especially the top of the panels, to be kept away from the shading area above the mounting surface, maximizing solar energy absorption and increasing the actual power generation (output power) of the photovoltaic panels. Simultaneously, it avoids hot spot effects, ensuring the lifespan of the photovoltaic panels. Furthermore, the installation of the photovoltaic panels using the stops and drag plates on the mounting rods (i.e., the mounting rods are longer than the width of the photovoltaic panel frame) improves the stability and reliability of the photovoltaic panel assembly in its unfolded state. Conversely, the assembly of the bracket and photovoltaic panels is achieved by nesting the mounting rods within the frame of the photovoltaic panel (i.e., the mounting rods are shorter and do not exceed the width of the photovoltaic panel frame). This ensures that the bracket does not exceed the width of the photovoltaic panel frame when folded and stored, improving the neatness of the photovoltaic panel assembly in its stored state and further facilitating transportation and storage.
[0041] Other features and corresponding beneficial effects of this application will be described in the latter part of the specification, and it should be understood that at least some of the beneficial effects will become obvious from the description in this application.

[0059] Please see Figure 1 , Figure 1 This is a schematic diagram of the existing photovoltaic panel support system in use, which is also a structural schematic diagram of the existing photovoltaic panel assembly.
[0060] A photovoltaic panel assembly includes a photovoltaic panel and a photovoltaic panel support. The photovoltaic panel 1 is typically composed of multiple solar cells and is set within a frame 11 and assembled with the photovoltaic panel support via the frame 11.
[0061] Existing photovoltaic panel brackets typically include two three-bar main structures: a back bar 21, a mounting bar 23, and a support bar 24. The support bar 24 is usually telescopic, thereby adjusting the tilt angle (i.e., the first angle) of the photovoltaic panel 1. Meanwhile, a stop bar 4 is set between the two mounting bars 23, and the photovoltaic panel 1 is fixed on the stop bar 4. A hook 7 is set at the top of the back bar 21, and a connecting bar 6 is set between the two back bars 21. The bracket is hung above the balcony through the hook 7 and connected to the balcony railing through the connecting bar 6, thereby ensuring that the bracket is stably and reliably installed on the balcony.
[0062] Although the existing triangular structure of the photovoltaic panel support is relatively stable and reliable, the photovoltaic panel 1 installed on the mounting rod 23 is close to the installation surface (i.e., the outer wall of the balcony) because the mounting rod 23 is directly connected to the back rod 21. Furthermore, there may be protrusions on the outer side of the balcony on the upper floor (such as clothes drying, flower pots, photovoltaic panel modules, etc.), which makes the photovoltaic panel 1 installed on the lower balcony easily blocked or located in its shadow. That is, the amount of sunlight received by the cells in the blocked area is drastically reduced or zero, which makes the overall actual power generation (output power) of the photovoltaic panel 1 lower than the theoretical state. In addition, the area is prone to hot spot effect, which not only further reduces the power generation, but also easily damages the cells and shortens the life of the photovoltaic panel module.
[0063] Although the distance between the top of the photovoltaic panel 1 and the mounting surface can be increased by installing the photovoltaic panel 1 downward relative to the top of the mounting rod 23, the height of the balcony itself is limited (the photovoltaic panel 1 usually cannot protrude from the bottom of the balcony), and in order to ensure the stability and reliability of the installation of the photovoltaic panel 1, it is difficult to achieve an effective distance between the top of the photovoltaic panel 1 and the mounting surface by installing the photovoltaic panel 1 downward.
[0064] At the same time, ease of installation also needs to be considered. The photovoltaic panels 1 on household balconies are usually installed by the users themselves. If the photovoltaic panels 1 need to be disassembled and reassembled from the bracket, it will greatly increase the difficulty of operation for the users and make it difficult to guarantee the safety of the photovoltaic panels 1 after reinstallation.
[0065] Of course, the photovoltaic panel 1 can also be installed on the ground or wall using a bracket. When installed on the wall, it is also subject to shading from above; when installed on the ground, because the triangular bracket is close to the ground, the end of the photovoltaic panel 1 is also close to the ground. In windy and rainy weather, dust on the ground is easily blown back by the wind or rain splashed onto the surface of that end of the photovoltaic panel 1, causing shading.
[0066] Example 1:
[0067] Please see Figure 2-5 , Figure 2 This is a schematic diagram illustrating the usage status of the photovoltaic panel support in this application; Figure 3 for Figure 1 A side view of the structure in the deployed state of the support frame; Figure 4 for Figure 1 A side view of the bracket in its folded state; Figure 5 This is a schematic diagram of the assembled structure of the four-bar linkage 2 and the fixing rod 3 in the photovoltaic panel support of this application.
[0068] To reduce shading and increase the actual power generation of the photovoltaic panel 1, this application provides a photovoltaic panel support, including at least two four-bar linkages 2. The at least two four-bar linkages 2 are used to install the photovoltaic panel 1, and the photovoltaic panel 1 is placed at a first angle. The first angle allows the photovoltaic panel 1 to tilt to maximize the light energy input, thereby increasing the actual power generation. At the same time, compared with the three-bar linkage structure of conventional supports, the four-bar linkage structure allows the top of the photovoltaic panel 1 to be away from the mounting surface, thereby reducing the shading it receives and increasing the actual power generation of the photovoltaic panel 1.
[0069] Furthermore, the four-bar linkage 2 of this bracket is also connected to a fixing rod 3, which is used to support and fix the four-bar linkage 2, thereby ensuring the stability and reliability of the four-bar linkage structure, that is, the stability and reliability of the bracket, and ensuring the safety of the photovoltaic panel 1.
[0070] Specifically, the four-bar linkage 2 includes:
[0071] Back rod 21 is used for fixed installation on the external mounting surface;
[0072] Mounting rod 23 is used to mount photovoltaic panel 1;
[0073] The support rod 24 connects the back rod 21 and the mounting rod 23, and the mounting rod 23 is inclined at a first angle relative to the back rod 21.
[0074] An extension rod 22 is positioned away from the support rod 24 and connects the end of the back rod 21 and the end of the mounting rod 23. When the bracket is in the extended state, the top of the mounting rod 23 and the back rod 21 have a first distance in a first direction, which is perpendicular to the mounting surface. This means that the top of the mounting rod 23 is a distance of the first distance from the mounting surface (e.g., the outer wall of the balcony). Consequently, the top of the photovoltaic panel 1 mounted on the mounting rod 23 is also a distance of the first distance from the mounting surface (e.g., the outer wall of the balcony), thus avoiding shading, fully receiving solar energy, increasing the actual power generation (output power) of the photovoltaic panel 1, and avoiding hot spot effects to ensure the lifespan of the photovoltaic panel 1.
[0075] In one embodiment, the support includes two four-bar linkages 2 arranged in parallel. The distance between the two four-bar linkages 2 can be equal to the length of the photovoltaic panel 1. This arrangement ensures that both ends of the photovoltaic panel 1 are supported by the four-bar linkages 2, guaranteeing stability. Of course, the distance between the two four-bar linkages 2 can also be less than the length of the photovoltaic panel 1, meaning that both ends of the photovoltaic panel 1 are not supported by the four-bar linkages 2. This embodiment does not specifically limit the distance between adjacent four-bar linkages 2, that is, it does not limit the support position of the four-bar linkages 2 on the photovoltaic panel 1, and can be adjusted according to the actual situation.
[0076] In other alternative solutions, this support structure can also employ at least three or more four-bar linkage components 2. Using three four-bar linkage components 2 enhances the overall stability of the photovoltaic panel 1. When only two four-bar linkage components 2 are used to fix and support the photovoltaic panel 1, compared to solutions with more than two four-bar linkage components 2, costs can be saved and the overall weight of the photovoltaic panel support structure can be reduced. Therefore, the number and spacing of the four-bar linkage components 2 are not specifically limited in this application.
[0077] In one embodiment, one end of the support rod 24 is connected to the end of the back rod 21 away from the extension rod 22, and the other end is connected to the middle of the mounting rod 23. That is, the connection position between the other end of the support rod 24 and the mounting rod 23 is located in the middle of the mounting rod 23, rather than at both ends of the mounting rod 23. This allows the mounting rod 23 to be tilted at a first angle relative to the back rod 21 with a shorter length, controlling costs and providing space for the subsequent installation of the fixing rod 3.
[0078] In one embodiment, the four connection endpoints of the four-bar linkage 2 are a first end 201, a second end 202, a third end 203 and a fourth end 204, respectively. The first end 201 is located between the back bar 21 and the extension bar 22, the second end 202 is located between the extension bar 22 and the mounting bar 23, the third end 203 is located between the mounting bar 23 and the support bar 24, and the fourth end 204 is located between the support bar 24 and the back bar 21.
[0079] The first end 201, the second end 202, the third end 203, and the fourth end 204 are rotatable connection points during the unfolding and folding of the bracket. That is, during the unfolding and folding process, the connection structure (e.g., bolts or rivets) of the first end 201, the second end 202, the third end 203, and the fourth end 204 can be unlocked, allowing the back rod 21, the extension rod 22, the mounting rod 23, and the support rod 24 to rotate relative to each other, thus enabling the folding or unfolding of the four-bar assembly 2. When the four-bar assembly 2 is folded or unfolded, the connection structure of the first end 201, the second end 202, the third end 203, and the fourth end 204 can be locked, preventing relative rotation of the back rod 21, the extension rod 22, the mounting rod 23, and the support rod 24, achieving relative fixation and thus stabilizing the bracket in its folded or unfolded state to a certain extent. Furthermore, the four-bar assembly 2 maintains the connection state of each rod regardless of whether it is folded or unfolded, thereby reducing isolated parts, further improving transport and storage portability, and facilitating user folding, storage, and unfolding operations.
[0080] In one embodiment, during the folding process of the bracket, the extension rod 22 and the mounting rod 23 fold relative to each other around the second end 202, and the back rod 21 and the support rod 24 fold relative to each other around the fourth end 204, i.e. Figure 3 As shown, the mounting rod 23 can be moved in the direction indicated by arrow A to achieve the above-mentioned folding.
[0081] The distance between the first end 201 and the second end 202 is a (this distance is basically equal to the length of the extension rod 22), the distance between the second end 202 and the third end 203 is b, the distance between the third end 203 and the fourth end 204 is c (this distance is basically equal to the length of the support rod 24), and the distance between the fourth end 204 and the first end 201 is d (this distance is basically equal to the length of the back rod 21), and b+c=a+d, a<b.
[0082] By designing the connection endpoints and spacing of the four-bar linkage 2, the four-bar linkage 2 can be folded. When folded, the back rod 21, extension rod 22, mounting rod 23 and support rod 24 of the four-bar linkage 2 can be as close as possible and avoid collision of the connection endpoints, thereby controlling the volume of the folded bracket and making it easier to transport and store.
[0083] In one embodiment, both the extension rod 22 and the support rod 24 include two symmetrically arranged first clamping portions 205. The two first clamping portions 205 are located on both sides of the corresponding connection endpoints, that is, the two ends of the two first clamping portions 205 of the extension rod 22 are respectively clamped on both sides of the ends of the back rod 21 and the mounting rod 23, and the two ends of the two first clamping portions 205 of the support rod 24 are respectively clamped on both sides of the other end of the back rod 21 and both sides of the mounting rod 23 corresponding to the third end 203.
[0084] This method allows the mounting rod 23 and the back rod 21 to overlap or stack when the bracket is folded. This means that when the bracket is folded, the back rod 21, extension rod 22, mounting rod 23 and support rod 24 can be brought closer together, thereby further reducing the folded volume and making the folded bracket more regular in shape, thus further facilitating transportation and storage.
[0085] In one embodiment, both the mounting rod 23 and the back rod 21 have U-shaped cross sections, and their openings face each other.
[0086] The four connection ends of the four-bar linkage 2 are formed by drilling holes and fasteners on the side walls of the U-shaped grooves of the corresponding mounting rod 23 and back rod 21, respectively. That is, the first end 201, the second end 202, the third end 203 and the fourth end 204 are all located on the back rod 21 or the mounting rod 23. The back rod 21, the extension rod 22, the mounting rod 23 and the support rod 24 are connected by overlapping ends and drilling holes and fasteners.
[0087] At this time, in order to further improve the closeness of the back rod 21 and the mounting rod 23 when folded, the mounting rod 23 is provided with a first clearance opening 231 corresponding to the first end 201 to avoid the fastener of the first end 201, and the back rod 21 is provided with a second clearance opening 211 corresponding to the third end 203 to avoid the fastener of the third end 203; and so that when the bracket is folded, the mounting rod 23 and the back rod 21 are in an overlapping state.
[0088] It should be noted that this overlap includes both complete overlap and partial overlap.
[0089] When only the first clearance opening 231 and the second clearance opening 211 are provided, the ends of the mounting rod 23 and the back rod 21 that are far from the extension rod 22 are difficult to completely overlap due to the presence of the fourth end fastener 204.
[0090] In other alternative embodiments, the mounting rod 23 is provided with a third clearance opening corresponding to the fourth end 204 to avoid the fasteners of the fourth end 204, thereby enabling the mounting rod 23 and the back rod 21 to completely overlap. However, in this case, since the connection between the fixing rod 3 and the mounting rod 23 is close to the third clearance opening, the two overlap, resulting in a weaker strength of the mounting rod 23 at that point, which has a certain impact on the stability and reliability of the bracket.
[0091] In one embodiment, the back rod 21 corresponding to the first end 201 and the fourth end 204, and the mounting rod 23 corresponding to the second end 202 and the third end 203 are all fixed with relatively protruding connecting blocks. That is, the first end 201, the second end 202, the third end 203 and the fourth end 204 are all located on the connecting blocks. The back rod 21, the extension rod 22, the mounting rod 23 and the support rod 24 are connected through the connecting blocks at the ends, thereby avoiding the need to drill holes on each rod and affecting the strength.
[0092] At this point, to further improve the closeness between the back rod 21 and the mounting rod 23 when folded, the connecting block includes two symmetrically arranged second clamping parts, which are respectively connected to the corresponding two first clamping parts 205 to form connecting endpoints. This ensures that when the bracket is folded, the fixing rod 3 is nested within the two first clamping parts 205 of the support rod 24 and the corresponding second clamping parts of the connecting block, and the mounting rod 23 and the back rod 21 are stacked together via the connecting block.
[0093] In one embodiment, the extension rod 22 and the support rod 24 include two symmetrically arranged clamping plates, and the two clamping plates are two first clamping parts 205, which has a simple structure.
[0094] At this point, the strength of the clamping plate can be ensured by bending it outwards from both sides. Alternatively, its strength can be ensured directly by using a clamping plate of a certain thickness.
[0095] In other alternative embodiments, the extension rod 22 and the support rod 24 have U-shaped cross sections, and the two side walls of the U-shaped groove are two first clamping parts 205, so that the two first clamping parts 205 form a whole, which is convenient for assembly.
[0096] In one embodiment, the two ends of the fixing rod 3 are respectively connected to the support rod 24 and the mounting rod 23, and are close to the end of the mounting rod 23 away from the extension rod 22. That is, the connection between the fixing rod 3 and the mounting rod 23 is located between the end of the support rod 24 and the end of the mounting rod 23 away from the extension rod 22, so that the mounting rod 23 is connected to the extension rod 22, the support rod 24 and the fixing rod 3 in sequence along its length direction, and the mounting rod 23, the fixing rod 3 and the support rod 24 form a triangular structure located outside the four-bar linkage 2.
[0097] Specifically, by placing the fixing rod 3 between the support rod 24 and the mounting rod 23, and located outside the four-bar assembly 2, a triangular support is formed on the outer side of the four-bar assembly 2, further improving the stability and reliability of the four-bar assembly 2. Furthermore, by forming a three-point support along the length of the mounting rod 23 through the extension rod 22, the support rod 24, and the fixing rod 3, the weight of the photovoltaic panel 1 on the mounting rod 23 can be better distributed, further improving the stability and reliability of the bracket, thereby further ensuring the installation stability and reliability of the photovoltaic panel 1.
[0098] In other words, by combining quadrilaterals and triangles, the overall slenderness ratio of the stent is reduced, thereby improving the stability and reliability of the stent.
[0099] Preferably, the fixing rod 3 is connected to the middle of the support rod 24, and the support rod 24 is connected to 1 / 3 of the mounting rod 23 and close to the extension rod 22, thereby further improving the stability and reliability of the bracket.
[0100] In other alternative embodiments, the two ends of the fixing rod 3 are respectively connected to the support rod 24 and the mounting rod 23, and the mounting rod 23 is positioned close to the end of the extension rod 22, such that the mounting rod 23 sequentially connects the extension rod 22, the fixing rod 3, and the support rod 24 along its length, forming a triangular structure inside the four-bar assembly 2. This method reduces the protruding structure of the bracket and lowers its risk of collision damage.
[0101] In one embodiment, the fixed rod 3 is slidably connected to one of the support rod 24 and the mounting rod 23, and the four-bar linkage 2 is foldable, thereby enabling the bracket to be folded as a whole.
[0102] In one specific embodiment, the fixing rod 3 and the mounting rod 23 are slidably connected, and during the folding process of the bracket, the fixing rod 3 slides along the mounting rod 23, so that the bracket can be folded. That is, during the folding and unfolding process of the bracket, not only does the four-bar assembly 2 remain connected, but the fixing rod 3 also remains connected to the four-bar assembly 2, thereby further reducing isolated parts, further improving the portability of transportation and storage, and also facilitating the user's folding, storage and unfolding operation.
[0103] In one specific embodiment, the fixed rod 3 and the support rod 24 are detachably connected, and during the folding process of the bracket, the fixed rod 3 and the support rod 24 are in a disassembled and separated state, so that the bracket can be folded. That is, during the folding and unfolding process of the bracket, the fixed rod 3 is separated from the four-bar assembly 2, thereby making the size of each rod more reasonable and the support distribution more optimized.
[0104] In one embodiment, the mounting rod 23 is provided with multiple fixing holes 232. The fixing rod 3 is engaged with any of the fixing holes 232 by a snap-fit component to adjust the first angle, and is locked in place by a locking component. That is, by adjusting the connection position between the fixing rod 3 and the mounting rod 23, the four-bar linkage 2 is rotated, thereby changing the angle between the mounting rod 23 and the back rod 21, i.e., changing the first angle.
[0105] Preferably, in order to allow the fixing rod 3 and the mounting rod 23 to be slidably connected, the multiple fixing holes 232 are connected, and the snap-fit can be disengaged from the fixing holes 232, and the locking member can slide between the multiple fixing holes 232.
[0106] In one specific embodiment, the size of the snap-fit component is adapted to the fixing hole 232 and can be inserted into the fixing hole 232 and the fixing rod 3; the size of the locking component is smaller than the fixing hole 232, and the locking component can pass through the snap-fit component and the fixing rod 3 in sequence to achieve locking.
[0107] In one embodiment, the mounting rod 23 is provided with a sliding groove, and the fixing rod 3 is slidably connected to the sliding groove via a slider to adjust the first angle and lock it in place.
[0108] In one embodiment, there is a gap between the two first clamping portions 205 of the fixing rod 3 and the support rod 24, so that when the fixing rod 3 and the support rod 24 are locked, the support rod 24 elastically deforms and forms an elastic fastening force on the third end 203, the fourth end 204 and the connection between the fixing rod 3 and the support rod 24, thereby improving the connection reliability of each connection end, and thus improving the stability and reliability of the bracket.
[0109] In particular, when the four connection ends of the four-bar linkage 2 are formed by opening holes in the side walls of the U-shaped grooves of the corresponding mounting rods 23 and back rods 21 and setting fasteners, in order to achieve the overlap of the back rods 21 and mounting rods 23, there needs to be a certain gap at the connection ends. For example, there is a certain gap at the overlap position of the two first clamping parts 205 of the support rod 24 and the connection of the back rods 21 and mounting rods 23. By locking the fixed rods 3 and the support rods 24, the support rods 24 can be elastically deformed, which can make the connection between the two ends of the support rods 24 and the back rods 21 and mounting rods 23 more stable and reliable.
[0110] In one embodiment, the back pole 21, extension pole 22, mounting pole 23, support pole 24, and fixing pole 3 are made of stainless steel or aluminum alloy. Stainless steel provides high strength, thus increasing the reliability of the support structure; while aluminum alloy provides lighter weight, improving the safety of the photovoltaic panel 1 after installation.
[0111] Example 2:
[0112] This application embodiment also provides a photovoltaic panel assembly, including the bracket of embodiment 1 and photovoltaic panel 1. Through the extension rod 22 and the fixing rod 3 of the bracket, the photovoltaic panel 1 can be stably and reliably pushed away from the mounting surface at a certain distance, so that the photovoltaic panel 1, especially the top of the photovoltaic panel 1, can be away from the shading area above the mounting surface, fully receive solar energy, improve the actual power generation (output power) of the photovoltaic panel 1, and at the same time, avoid the hot spot effect and ensure the life of the photovoltaic panel 1.
[0113] In one embodiment, the mounting rod 23 of the bracket is fixed with a stop bar 4 and a drag bar 5. The stop bar 4 is located near the extension rod 22, and the drag bar 5 is located at the end of the mounting rod 23 away from the extension rod 22. The top of the frame 11 of the photovoltaic panel 1 is connected to the stop bar 4, and the bottom of the frame 11 of the photovoltaic panel 1 is supported by the drag bar 5. In this method, the mounting rod 23 is relatively long, exceeding the width of the frame 11 of the photovoltaic panel 1, which can improve the stability and reliability of the photovoltaic panel module in the unfolded state.
[0114] In one embodiment, a connecting rod 6 is provided between the two back bars 21 of the two four-bar linkages 2 to connect to the mounting surface, such as a balcony railing, to improve the stability of the bracket. Hooks 7 are provided at the top of the two back bars 21 of the two four-bar linkages 2 to hang the entire bracket on the balcony.
[0115] In one embodiment, the mounting rod 23 of the bracket is nested within the frame 11 of the photovoltaic panel 1, and its two ends are fixed to the top and bottom of the frame 11 of the photovoltaic panel 1, respectively. In this method, the mounting rod 23 is relatively short and does not exceed the width of the frame 11 of the photovoltaic panel 1, so that the bracket does not exceed the width of the frame 11 of the photovoltaic panel 1 when folded and stored, which can improve the neatness of the photovoltaic panel module in the stored state and further facilitate transportation and storage.
