[0002] With the progress of photovoltaic power generation technology, the application range of photovoltaic power generation is more and more extensive, and household photovoltaic power generation develops rapidly. However, the current photovoltaic power generation has certain limitations and can only be installed on the sloping roof of a villa or the flat roof of a bungalow. For high-rise buildings, the installation utilization rate is low.

[0003] At present, photovoltaic panel supports installed on balconies also appear on the market, and the photovoltaic panel supports can adjust the angle of the photovoltaic panel to ensure the power generation efficiency of the photovoltaic panel. However, since the top of the photovoltaic panel is close to the balcony, the upper part of the photovoltaic panel is easily blocked by the protruding object above or located in the shadow above, so that the actual power generation is still not ideal. SUMMARY

[0018] According to the technical scheme, the extension rod and the support rod are clamped on both sides of the connecting end point, so that the back rod, the extension rod, the mounting rod and the support rod are closer to each other when the support is folded, thereby further reducing the folding volume and making the shape of the folded support more regular, thereby further facilitating transportation and storage.

[0019] In some embodiments, the mounting rod and the back rod are both U-shaped in cross section, and the openings of the two are opposite to each other;

[0020] The four connecting end points of the four-bar linkage assembly are formed by opening holes in the side walls of the U-shaped slots of the mounting rod and the back rod and arranging fasteners;

[0024] In some embodiments, the extension rod and the support rod are U-shaped in cross section, and the two side walls of the U-shaped slot are the two first clamping parts; or,

[0025] The extension rod and the support rod include two clamping plates arranged symmetrically, and the two clamping plates are the two first clamping parts.

[0026] In some embodiments, the two ends of the fixed rod are connected to the support rod and the mounting rod respectively, and are close to the end of the mounting rod away from the extension rod, so that the mounting rod is sequentially connected to the extension rod, the support rod and the fixed rod along the length direction of the mounting rod, and the mounting rod, the fixed rod and the support rod form a triangular structure outside the four-bar linkage assembly.

[0027] By adopting the above technical solution, the fixing rod is set between the support rod and the mounting rod, and is located outside the four-bar assembly, that is, a triangular support is formed on the outside of the four-bar assembly, thereby further improving the stability and reliability of the four-bar assembly; and, by forming a three-point support along the length direction of the mounting rod through the extension rod, the support rod and the fixing rod, the gravity of the photovoltaic panel on the mounting rod can be better dispersed, thereby further improving the stability and reliability of the bracket, thereby further ensuring the installation stability and reliability of the photovoltaic panel.

[0033] In some embodiments, a sliding groove is provided on the mounting rod, and the fixing rod is slidably connected to the sliding groove via a slider to adjust the first angle and can be locked and fixed.

[0034] In some embodiments, there is a gap between the two first clamping portions of the fixing rod and the support rod, so 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.

[0035] The embodiment of the present application further provides a photovoltaic panel assembly, comprising any of the above-mentioned brackets, and a photovoltaic panel;

[0037] The mounting rod of the bracket is nested in the frame of the photovoltaic panel, and both ends are fixed to the top and bottom of the frame of the photovoltaic panel respectively.

[0038] By means of the extension rod and the fixing rod of the support, the photovoltaic panel is stably and reliably pushed away from the installation surface by a certain distance, so that the photovoltaic panel, especially the top of the photovoltaic panel, can be far away from the shadow area above the installation surface, fully receive solar energy, improve the actual power generation (output power) of the photovoltaic panel, and avoid the hot spot effect, thereby ensuring the service life of the photovoltaic panel. In addition, the photovoltaic panel is installed by means of the stop rod and the drag piece on the mounting rod, i.e., the mounting rod is long and exceeds the width of the frame of the photovoltaic panel, so that the stability and reliability of the photovoltaic panel assembly in the unfolded state can be improved. The mounting rod is nested in the frame of the photovoltaic panel to assemble the support and the photovoltaic panel, i.e., the mounting rod is short and does not exceed the width of the frame of the photovoltaic panel, so that the mounting rod does not exceed the width of the frame of the photovoltaic panel when the support is folded and stored, and the regularity of the photovoltaic panel assembly in the storage state can be improved, thereby further facilitating transportation and storage.

[0057] Please refer to Figure 1 , Figure 1 is a schematic view of the use state of the existing photovoltaic panel support, that is, a schematic view of the structure of the existing photovoltaic panel assembly.

[0058] The photovoltaic panel assembly includes a photovoltaic panel and a photovoltaic panel support. The photovoltaic panel 1 is usually composed of a plurality of cell pieces and is arranged in a frame 11 and assembled with the photovoltaic panel support through the frame 11.

[0059] The existing photovoltaic panel support usually includes two three-link main body structures, namely back rods 21, mounting rods 23 and support rods 24. The support rods 24 are usually telescopic, so as to adjust the inclination angle (i.e. the first angle) of the photovoltaic panel 1. At the same time, a stop rod 4 is arranged between the two mounting rods 23, the photovoltaic panel 1 is fixed on the stop rod 4, a hook 7 is arranged at the top of the back rod 21, a connecting rod 6 is arranged between the two back rods 21, and the hook 7 is hung above the balcony, and the connecting rod 6 is connected with the balcony rail, so as to ensure that the support is stably and reliably installed on the balcony.

[0060] Although the triangular structure of the existing photovoltaic panel support is relatively stable and reliable, since the mounting rod 23 is directly connected with the back rod 21, the photovoltaic panel 1 mounted on the mounting rod 23 is relatively close to the installation surface (i.e. the outer wall of the balcony), and there can be protrusions (such as clothes for drying, flowerpots, photovoltaic panel assemblies, etc.) on the outer side of the balcony of the floor above, which can cause the photovoltaic panel 1 mounted on the balcony below to be easily blocked or located in the shadow, i.e. the amount of light received by the cell pieces in the blocked area is sharply reduced or zero, thereby reducing the actual power generation (output power) of the photovoltaic panel 1 as a whole compared with the theoretical state, and the area is prone to hot spot effect, which not only further reduces the power generation, but also easily causes damage to the cell pieces and shortens the service life of the photovoltaic panel assembly.

[0061] Although the photovoltaic panel 1 can be mounted downward relative to the top of the mounting rod 23 to increase the distance between the top of the photovoltaic panel 1 and the installation surface, the height of the balcony itself is limited (the photovoltaic panel 1 generally cannot protrude the bottom surface 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 the effective distance between the top of the photovoltaic panel 1 and the installation surface by mounting the photovoltaic panel 1 downward.

[0062] At the same time, the installation convenience also needs to be considered, and the photovoltaic panel 1 of the household balcony is usually installed by the user himself, and if the photovoltaic panel 1 needs to be reassembled from the support, it greatly increases the difficulty of the user's operation, and it is difficult to ensure the safety of the photovoltaic panel 1 after reinstallation.

[0063] Of course, the photovoltaic panel 1 can also be installed on the ground or the wall surface by the support (in which case the hook 7 is not needed). When installed on the wall surface, the problem of being blocked from above still exists; when installed on the ground, since the triangular support is close to the ground, the end of the photovoltaic panel 1 is also close to the ground, and in windy and rainy weather, the dust on the ground is easily rolled back by the wind or splashed by the rain to the end surface of the photovoltaic panel 1, causing blocking.

[0064] Embodiment 1:

[0065] Please refer to Figures 2-5 , Figure 2 is a use state schematic view of the photovoltaic panel support of the present application; Figure 3 is Figure 1 is a side view structural schematic view of the support of the present application in the unfolded state; Figure 4 is Figure 1 is a side view structural schematic view of the support of the present application in the folded state; Figure 5 is a structural schematic view of the four-bar linkage assembly 2 and the fixed rod 3 of the photovoltaic panel support of the present application after assembly.

[0066] In order to reduce the shading and improve the actual power generation of the photovoltaic panel 1, the embodiment of the present application provides a photovoltaic panel support, which comprises at least two four-bar linkage assemblies 2, the at least two four-bar linkage assemblies 2 are used for mounting the photovoltaic panel 1 and enabling the photovoltaic panel 1 to be placed at a first angle, the first angle can enable the photovoltaic panel 1 to be inclined to maximize the input of light energy, thereby improving the actual power generation; meanwhile, compared with the three-bar linkage structure of the conventional support, the four-bar linkage structure enables the top of the photovoltaic panel 1 to be far away from the mounting surface, thereby reducing the shading and improving the actual power generation of the photovoltaic panel 1.

[0067] Meanwhile, the four-bar linkage assembly 2 of the support is further connected with a fixing rod 3, the fixing rod 3 is used for supporting and fixing the four-bar linkage assembly 2, thereby ensuring the stability and reliability of the four-bar linkage structure, i.e. the stability and reliability of the support, and ensuring the safety of the photovoltaic panel 1.

[0068] Specifically, the four-bar linkage assembly 2 comprises:

[0069] a back rod 21, which is used for being fixedly arranged on the external mounting surface;

[0070] a mounting rod 23, which is used for mounting the photovoltaic panel 1;

[0071] a supporting rod 24, which is connected with the back rod 21 and the mounting rod 23 and enables the mounting rod 23 to be inclined at a first angle relative to the back rod 21;

[0072] an extension rod 22, which is arranged away from the supporting rod 24 and is connected with the end of the back rod 21 and the end of the mounting rod 23, and in the unfolded state of the support, enables the top of the mounting rod 23 to have a first spacing with the back rod 21 in a first direction, the first direction being perpendicular to the mounting surface, i.e. enabling the top of the mounting rod 23 to be away from the mounting surface (such as the outer wall of the balcony or the ground, etc.) by a first spacing, thereby enabling the top of the photovoltaic panel 1 mounted on the mounting rod 23 to be also away from the mounting surface (such as the outer wall of the balcony or the ground, etc.) by the first spacing, so as to avoid the shading shadow or reduce the stain caused by the splashing, fully receive the solar energy, improve the actual power generation (output power) of the photovoltaic panel 1, and meanwhile, avoid the hot spot effect and ensure the service life of the photovoltaic panel 1.

[0073] In one embodiment, the support comprises two four-bar linkage assemblies 2, the two four-bar linkage assemblies 2 are arranged in parallel, and the distance between the two four-bar linkage assemblies 2 can be equal to the length of the photovoltaic panel 1, such an arrangement can enable the two ends of the photovoltaic panel 1 to be supported by the four-bar linkage assemblies 2, thereby ensuring the stability; of course, the distance between the two four-bar linkage assemblies 2 can also be less than the length of the photovoltaic panel 1, i.e. the two ends of the photovoltaic panel 1 are not supported by the four-bar linkage assemblies 2; the embodiment does not specifically limit the distance between the adjacent four-bar linkage assemblies 2, i.e. does not limit the support position of the four-bar linkage assemblies 2 on the photovoltaic panel 1, and the distance can be adjusted according to the actual situation.

[0074] In other alternative solutions, the support frame can also use at least three four-bar linkage assemblies 2. When three four-bar linkage assemblies 2 are used, the overall stability of the support for the photovoltaic panel 1 is enhanced. When only two four-bar linkage assemblies 2 are used to support the photovoltaic panel 1, compared with the solution of using more than two four-bar linkage assemblies 2, the cost can be saved and the overall weight of the photovoltaic panel support frame can be reduced. Therefore, the number and distance of the four-bar linkage assemblies 2 are not specifically limited in the present application.

[0075] 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, i.e., the other end of the support rod 24 is connected to the middle of the mounting rod 23, rather than the two ends of the mounting rod 23, so that the mounting rod 23 can be inclined at the first angle relative to the back rod 21 with a shorter length, the cost is controlled, and space is provided for the subsequent installation of the fixing rod 3.

[0076] In one embodiment, the four connection points of the four-bar linkage assembly 2 are the first end 201, the second end 202, the third end 203, and the fourth end 204, and the first end 201 is located between the back rod 21 and the extension rod 22, the second end 202 is located between the extension rod 22 and the mounting rod 23, the third end 203 is located between the mounting rod 23 and the support rod 24, and the fourth end 204 is located between the support rod 24 and the back rod 21.

[0077] The first end 201, the second end 202, the third end 203, and the fourth end 204 are rotating connection points during the unfolding and folding of the support frame, i.e., during the unfolding and folding of the support frame, the back rod 21, the extension rod 22, the mounting rod 23, and the support rod 24 can be relatively rotated by unlocking the connection structure (such as a bolt or a rivet) of the first end 201, the second end 202, the third end 203, and the fourth end 204, so as to realize the folding or unfolding of the four-bar linkage assembly 2. When the four-bar linkage assembly 2 is folded or unfolded in place, the connection structure of the first end 201, the second end 202, the third end 203, and the fourth end 204 can be locked, so that the back rod 21, the extension rod 22, the mounting rod 23, and the support rod 24 cannot be relatively rotated, and are relatively fixed, thereby achieving a certain degree of stability of the folded or unfolded state of the support frame. Moreover, the four-bar linkage assembly 2 can maintain the connection state of each rod whether it is folded or unfolded, thereby reducing isolated parts, further improving the portability of transportation and storage, and also facilitating the folding and storage of users and the unfolding and use operation.

[0078] In one embodiment, during the folding of the support frame, the extension rod 22 and the mounting rod 23 are relatively folded around the second end 202, and the back rod 21 and the support rod 24 are relatively folded around the fourth end 204, i.e., as shown in Figure 3 the mounting rod 23 moves in the direction indicated by arrow A, the above folding can be achieved.

[0079] The distance between the first end 201 and the second end 202 is a (the distance is substantially 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 (the distance is substantially equal to the length of the support rod 24), the distance between the fourth end 204 and the first end 201 is d (the distance is substantially equal to the length of the back rod 21), and b + c = a + d, a < b.

[0080] That is, by designing the connection end points and the distances of the four-bar linkage assembly 2, the four-bar linkage assembly 2 can be folded, and when folded, the back rod 21, the extension rod 22, the mounting rod 23 and the support rod 24 of the four-bar linkage assembly 2 can be as close as possible and avoid collision of the connection end points, thereby controlling the volume of the folded bracket and facilitating transportation and storage.

[0081] In an embodiment, the extension rod 22 and the support rod 24 each include two first clamping portions 205 arranged symmetrically. The two first clamping portions 205 are respectively located on both sides of the corresponding connection end points, 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 end portions 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 portion of the back rod 21 and both sides of the mounting rod 23 corresponding to the third end 203.

[0082] This mode can realize that the mounting rod 23 and the back rod 21 are in an overlapping or laminated state when the bracket is folded, that is, the back rod 21, the extension rod 22, the mounting rod 23 and the support rod 24 can be further close to fit when the bracket is folded, thereby further reducing the folded volume and making the shape of the folded bracket more regular, thereby further facilitating transportation and storage.

[0083] In an embodiment, the cross sections of the mounting rod 23 and the back rod 21 are both U-shaped, and the openings of the two are opposite.

[0084] The four connection end points of the four-bar linkage assembly 2 are formed by opening holes in the side walls of the U-shaped slots of the corresponding mounting rod 23 and back rod 21 and setting fasteners, 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, and the back rod 21, the extension rod 22, the mounting rod 23 and the support rod 24 are connected by overlapping the end portions and opening holes and setting fasteners.

[0085] At this time, in order to further improve the close degree of the back rod 21 and the mounting rod 23 when folded, the mounting rod 23 is provided with a first avoiding 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 avoiding opening 211 corresponding to the third end 203 to avoid the fastener of the third end 203; and the mounting rod 23 and the back rod 21 are in an overlapping state when the support is in a folded state.

[0086] It should be noted that the overlapping state includes complete overlapping and also includes partial overlapping.

[0087] When only the first avoiding opening 231 and the second avoiding opening 211 are provided, due to the existence of the fastener of the fourth end 204, the end of the mounting rod 23 and the back rod 21 away from the extension rod 22 is difficult to completely overlap.

[0088] In other alternative embodiments, the mounting rod 23 is provided with a third avoiding opening corresponding to the fourth end 204 to avoid the fastener of the fourth end 204, so that the mounting rod 23 and the back rod 21 can completely overlap. However, at this time, the connection between the fixing rod 3 and the mounting rod 23 is close to the third avoiding opening, and the two are superimposed, resulting in a weak strength of the mounting rod 23 at this position, which has a certain influence on the stability and reliability of the support.

[0089] In one embodiment, the back rod 21 is fixed with a relatively protruding connecting block corresponding to the first end 201 and the fourth end 204, and the mounting rod 23 is fixed with a relatively protruding connecting block corresponding to the second end 202 and the third end 203, 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 block, and the back rod 21, the extension rod 22, the mounting rod 23 and the support rod 24 are connected through the connecting block at the end, so as to avoid opening holes on each rod and affect the strength.

[0090] At this time, in order to further improve the close degree of the back rod 21 and the mounting rod 23 when folded, the connecting block includes two symmetrically arranged second clamping portions, and the two second clamping portions are connected with the corresponding two first clamping portions 205 to form connecting end points. And in the folded state of the support, the fixing rod 3 is nested in the two first clamping portions 205 of the support rod 24 and the second clamping portions of the corresponding connecting block, and the mounting rod 23 and the back rod 21 are in a stacked state through the connecting block.

[0091] In one embodiment, the extension rod 22 and the support rod 24 include two symmetrically arranged clamping plates, and the two clamping plates are respectively two first clamping portions 205, which is simple in structure.

[0092] At this time, the strength of the clamping plate can be ensured by bending the two sides of the clamping plate outward. The strength of the clamping plate can also be ensured directly by a clamping plate with a certain thickness.

[0093] In other alternative embodiments, the cross section of the extension rod 22 and the support rod 24 is in the shape of a U, and the two side walls of the U-shaped groove are respectively two first clamping portions 205, so that the two first clamping portions 205 form an integral whole, facilitating assembly.

[0094] 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, so that the mounting rod 23 is sequentially connected to the extension rod 22, the support rod 24 and the fixing rod 3 along the length direction of the mounting rod 23, and the mounting rod 23, the fixing rod 3 and the support rod 24 form a triangular structure located outside the four-bar linkage assembly 2.

[0095] That is, by arranging the fixing rod 3 between the support rod 24 and the mounting rod 23 and outside the four-bar linkage assembly 2, a triangular support is formed outside the four-bar linkage assembly 2, further improving the stability and reliability of the four-bar linkage assembly 2. Moreover, by forming a three-point support along the length direction of the mounting rod 23 through the extension rod 22, the support rod 24 and the fixing rod 3, the gravity of the photovoltaic panel 1 received by the mounting rod 23 can be better dispersed, further improving the stability and reliability of the bracket, thereby further ensuring the installation stability and reliability of the photovoltaic panel 1.

[0096] That is, by the combination of the quadrilateral and the triangle, the overall slenderness ratio of the bracket is reduced, thereby improving the stability and reliability of the bracket.

[0097] 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.

[0098] 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 are close to the end of the mounting rod 23 close to the extension rod 22, so that the mounting rod 23 is sequentially connected to the extension rod 22, the fixing rod 3 and the support rod 24 along the length direction of the mounting rod 23, and the mounting rod 23, the fixing rod 3 and the support rod 24 form a triangular structure located inside the four-bar linkage assembly 2. This way can reduce the convex structure of the bracket, and reduce the risk of collision damage.

[0099] In one embodiment, the fixing rod 3 and the mounting rod 23 are slidably connected, and during folding of the bracket, the fixing rod 3 slides along the mounting rod 23, so that the bracket can be folded, that is, not only the four-bar linkage assembly 2 remains connected during folding and unfolding of the bracket, but also the fixing rod 3 remains connected to the four-bar linkage assembly 2, thereby further reducing isolated parts, further improving transportation and storage portability, and also facilitating folding and storage by the user and unfolding and use operation.

[0100] In one embodiment, the fixed rod 3 and the supporting rod 24 are detachably connected, and during the folding of the support, the fixed rod 3 and the supporting rod 24 are in a detached state, so that the support can be folded, that is, during the folding and unfolding of the support, the fixed rod 3 is separated from the four-bar linkage assembly 2, so that the size of each rod can be more reasonable, and the support distribution is more optimized.

[0101] In one embodiment, a plurality of fixing holes 232 are provided on the mounting rod 23, the fixed rod 3 is clamped with any fixing hole 232 through a clamping piece to adjust the first angle, and is locked and fixed through a locking piece. That is, the fixed rod 3 adjusts the connection position with the mounting rod 23 to realize the rotation of the four-bar linkage assembly 2, so as to realize the change of the included angle between the mounting rod 23 and the back rod 21, that is, the change of the first angle.

[0102] Preferably, in order to make the fixed rod 3 and the mounting rod 23 be slidably connected, the plurality of fixing holes 232 are communicated, and the clamping piece can be separated from the fixing hole 232, and the locking piece can slide between the plurality of fixing holes 232.

[0103] In one specific embodiment, the size of the clamping piece is adapted to the fixing hole 232, and the clamping piece can be inserted into the fixing hole 232 and the fixed rod 3; the size of the locking piece is smaller than the fixing hole 232, the locking piece can sequentially penetrate the clamping piece and the fixed rod 3, and locking is realized.

[0104] In one embodiment, a sliding groove is provided on the mounting rod 23, and the fixed rod 3 is slidably connected with the sliding groove through a sliding block to adjust the first angle, and can be locked and fixed.

[0105] In one embodiment, there is a gap between the fixed rod 3 and the two first clamping portions 205 of the supporting rod 24, so that when the fixed rod 3 and the supporting rod 24 are locked, the supporting rod 24 elastically deforms, and an elastic fastening force is formed on the third end 203, the fourth end 204, and the connection between the fixed rod 3 and the supporting rod 24, so as to improve the connection reliability of each connection end, and further improve the stability and reliability of the support.

[0106] Especially, when the four connection ends of the four-bar linkage assembly 2 are respectively formed by opening holes on the side walls of the U-shaped grooves of the corresponding mounting rod 23 and back rod 21 and setting fastening pieces, in order to realize the overlap of the back rod 21 and the mounting rod 23, a certain gap is required at the connection end, for example, the overlapping position of the two first clamping portions 205 of the supporting rod 24 and the connection between the back rod 21 and the mounting rod 23 has a certain gap, and through the locking of the fixed rod 3 and the supporting rod 24, the supporting rod 24 elastically deforms, so that the connection between the two ends of the supporting rod 24 and the back rod 21 and the mounting rod 23 is more stable and reliable.

[0107] In one embodiment, the materials of the back rod 21, the extension rod 22, the mounting rod 23, the support rod 24 and the fixing rod 3 are stainless steel or aluminum alloy. The rods are made of stainless steel, which has high strength, so that the bracket has high reliability. The rods are made of aluminum alloy, which has light weight, so that the safety of the photovoltaic panel 1 after installation can be improved.

[0108] Embodiment 2:

[0109] The embodiment of the present application also provides a photovoltaic panel assembly, which comprises the bracket of embodiment 1 and the photovoltaic panel 1. The bracket is used to push the photovoltaic panel 1 away from the installation surface by a certain distance through the extension rod 22 and the fixing rod 3, so that the photovoltaic panel 1, especially the top of the photovoltaic panel 1, can be far away from the shadow area above the installation surface, fully receive solar energy, improve the actual power generation (output power) of the photovoltaic panel 1, and avoid the hot spot effect, thereby ensuring the service life of the photovoltaic panel 1.

[0110] In one embodiment, the mounting rod 23 of the bracket is fixed with the stop rod 4 and the drag piece 5. The stop rod 4 is arranged close to the extension rod 22, and the drag piece 5 is arranged 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 with the stop rod 4, and the bottom of the frame 11 of the photovoltaic panel 1 is supported by the drag piece 5. In this way, the length of the mounting rod 23 is longer than the width of the frame 11 of the photovoltaic panel 1, so that the stability and reliability of the photovoltaic panel assembly in the unfolded state can be improved.

[0111] In one embodiment, a connecting rod 6 is arranged between the two back rods 21 of the two four-bar linkage assemblies 2 to be connected with the installation surface, for example, the balcony railing, so as to improve the stability of the bracket. Hooks 7 are arranged at the top of the two back rods 21 of the two four-bar linkage assemblies 2 to hang the bracket on the balcony.

[0112] In one embodiment, the mounting rod 23 of the bracket is nested in the frame 11 of the photovoltaic panel 1, and the two ends of the mounting rod 23 are fixed with the top and the bottom of the frame 11 of the photovoltaic panel 1, respectively. In this way, the length of the mounting rod 23 is shorter than 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 it is folded and stored, and the neatness of the photovoltaic panel assembly in the storage state can be improved, thereby facilitating transportation and storage.
