[0051] See also Figure 1-Figure 3 , Figure 1 A first schematic diagram of a photovoltaic mounting bracket provided by an embodiment of the present application with a photovoltaic assembly 800 installed thereon is shown. Figure 2 Shows Figure 1 The second schematic diagram shows a photovoltaic mounting bracket with a photovoltaic component 800 installed thereon. Figure 3 Shows Figure 1 The third schematic diagram shows a photovoltaic mounting bracket with a photovoltaic component 800 installed thereon.

[0052] The photovoltaic mounting bracket provided in one embodiment of the present application includes a first support plate 100, a crossbeam assembly 200 and a first telescopic member 300. The first support plate 100 is used to carry the photovoltaic assembly 800; the crossbeam assembly 200 includes at least two groups of crossbeam structures 210 spaced apart along a first direction; specifically, the first direction is Figure 1-Figure 3xx' direction in the figure; the beam structure 210 is used to carry the first support plate 100; the first telescopic member 300 is installed between two adjacent groups of beam structures 210; wherein the beam assembly 200 has a folded state and an unfolded state that can be switched to each other; when the beam assembly 200 switches from the folded state to the unfolded state, the beam structure 210 is deformed along the first direction and the second direction; the second direction is set at an angle to the first direction; specifically, the second direction is Figure 1-Figure 3 and the first telescopic member 300 extends along its own length direction to drive the first support plate 100 to move in the second direction and rotate around its own axis of rotation.

[0053] When the photovoltaic assembly 800 is installed by the photovoltaic mounting bracket provided by the embodiment of the present application, since the cross beam assembly 200 has a folded state and an unfolded state that can be switched to each other, the cross beam assembly 200 can be switched to the folded state during transportation, so that the entire photovoltaic mounting bracket occupies less space and is convenient for transportation. When it is transported to the destination for installation, the cross beam assembly 200 is switched to the unfolded state. During this process, the cross beam structure 210 is moved along the first direction ( Figure 1 xx' direction in the second direction ( Figure 2 The first telescopic member 300 is deformed in the direction of its own length, thereby driving the first support plate 100 to move in the second direction and rotate around its own rotation axis, thereby adjusting the installation height and angle of the photovoltaic assembly 800, and finally completing the installation and fixation of the photovoltaic assembly 800. Since the photovoltaic mounting bracket of the present application does not need to be installed and welded at the installation site, the installation process is relatively simple and the construction requirements are relatively low. At the same time, since the adjustment of the installation height and angle of the photovoltaic assembly 800 can be achieved by adjusting the state of the crossbeam assembly 200, the installation angle adjustment and maintenance of the photovoltaic assembly 800 in the later stage are also relatively convenient, which effectively reduces the use cost of the entire photovoltaic system.

[0054] It should be noted that the folding state of the photovoltaic mounting bracket can be as follows: Figure 1 As shown in FIG. 1 , the height of the entire photovoltaic mounting bracket along the second direction is relatively low. Of course, the photovoltaic mounting bracket can be further folded to further reduce the height of the entire photovoltaic mounting bracket along the second direction. Figure 2 As shown, the first support plate 100 is in a horizontal position relative to the installation plane; Figure 3 As shown, the first support plate 100 has a certain angle relative to the installation plane, which is not particularly limited and is adaptively adjusted according to the specific installation plane and the installation angle to be achieved.

[0055] It should be noted that the rotation axis of the first support plate 100 is the rotation axis of the connection between the first support plate 100 and the beam structure 210 .

[0056] The photovoltaic mounting bracket provided in the embodiment of the present application utilizes the folding geometry principle, so that it can be folded during transportation, taking up less space and having lower transportation cost. When it is installed and used, it can be unfolded again, which is simple and convenient.

[0057] Since the height and angle of the photovoltaic mounting bracket provided in the embodiment of the present application can be adjusted when the state of the beam assembly 200 is switched, it can adapt to different terrains and environmental conditions, such as mountains, deserts or roofs.

[0058] The photovoltaic mounting bracket provided in the embodiment of the present application can be adjusted to a folded state or retracted when encountering strong winds or severe weather conditions, thereby ensuring stability and safety.

[0059] The photovoltaic mounting bracket provided in the embodiment of the present application can drive the first support plate 100 to move along the second direction, so that the photovoltaic assembly 800 can be higher from the ground, and the photovoltaic assembly 800 is not easily blocked by grass. At the same time, it can also block dust caused by splashing water, so that the photovoltaic assembly 800 has a better photoelectric conversion effect.

[0060] The following is a detailed description of the structure of the photovoltaic mounting bracket. Figure 4-Figure 6 , Figure 4 Shows Figure 1 A schematic diagram of the connection between the third connecting rod 213 and the fourth connecting rod 214 in the photovoltaic mounting bracket is shown. Figure 5 Shows Figure 4 The diagram shows a connection diagram of the first mounting end 2131 of the third connecting rod 213 and the second mounting end 2141 of the fourth connecting rod 214. Figure 6 Shows Figure 1 The fourth schematic diagram shows a photovoltaic mounting bracket with a photovoltaic component 800 installed.

[0061] See also Figure 1-Figure 3 In some embodiments, the crossbeam structure 210 includes a plurality of connecting rods rotatably connected to each other. When the plurality of connecting rods rotate with each other, the crossbeam structure 210 can be deformed along the first direction and the second direction. By configuring the crossbeam structure 210 as a plurality of connecting rods rotatably connected to each other, when the connecting rods rotate, the entire crossbeam structure 210 can be deformed along the first direction and the second direction, thereby causing the first support plate 100 to move and rotate. In this way, the adjustment of the installation height and installation angle of the photovoltaic module 800 is realized in a simple and convenient manner, and the manufacturing cost of the entire crossbeam structure 210 is low.

[0062] See also Figure 1-Figure 3 In some embodiments, the crossbeam structure 210 includes a first connecting rod 211, a second connecting rod 212, a third connecting rod 213 and a fourth connecting rod 214 which are connected end to end in rotation; and the connection between the first connecting rod 211 and the second connecting rod 212 is connected to the first telescopic member 300 for rotation. Through the cooperation between the four connecting rods and the first telescopic member 300, when the connecting rods rotate with each other, the first telescopic member 300 is extended or shortened along its own length direction, thereby realizing the crossbeam assembly 200 in the Figure 1-Figure 3 Adjust the switch between any states.

[0063] See also Figure 1-Figure 3 In some embodiments, the cross beam structure 210 further includes a second telescopic member 215; one end of the second telescopic member 215 is connected to the connection between the first connecting rod 211 and the second connecting rod 212, and the other end of the second telescopic member 215 is connected to the connection between the third connecting rod 213 and the fourth connecting rod 214. By providing the second telescopic member 215, the four connecting rods rotate with each other, so that when the cross beam structure 210 is deformed, the cross beam structure 210 can be supported by the second telescopic member 215, making the entire cross beam structure 210 more stable.

[0064] See also Figure 1-Figure 3 In some embodiments, the first connecting rod 211, the second telescopic member 215 and the fourth connecting rod 214 are jointly arranged to form a first deformation structure; the second connecting rod 212, the third connecting rod 213 and the second telescopic member 215 are jointly arranged to form a second deformation structure. Specifically, the first deformation structure is a triangle, and the second deformation structure is also a triangle. The stability of the triangle makes the stability of the entire beam structure 210 higher.

[0065] See also Figure 1-Figure 3 In some embodiments, the photovoltaic mounting bracket further includes a first damper 410. The first damper 410 is mounted on the first connecting rod 211 and / or the second connecting rod 212. By mounting the first damper 410 on the first connecting rod 211 and / or the second connecting rod 212, the first damper 410 can effectively absorb vibration energy, protect the photovoltaic assembly 800, and make the wind resistance stability of the entire photovoltaic mounting bracket better, reduce the risk of hidden cracks of the photovoltaic assembly 800 under large vibration conditions, and extend the service life of the photovoltaic mounting bracket and the photovoltaic assembly 800. At the same time, the first damper 410 can also help control the speed and strength of folding and unfolding of the cross beam assembly 200 when switching between the folding state and the supporting state, so as to prevent instability or structural damage caused by rapid expansion and contraction. And reduce the safety risks caused by extreme weather or accidental impact; reduce the energy loss caused by vibration, improve the power generation efficiency of the photovoltaic system; reduce the noise that may be generated during the expansion and contraction process.

[0066] In one specific embodiment, the first damper 410 is installed on the first connecting rod 211. In another specific embodiment, the first damper 410 is installed on the second connecting rod 212. In another embodiment, the first connecting rod 211 and the second connecting rod 212 are both installed with the first damper 410.

[0067] In some embodiments, when the first damper 410 is installed on the first connecting rod 211, the first damper 410 is arranged along the extension direction of the first connecting rod 211. When the first damper 410 is installed on the second connecting rod 212, the first damper 410 is arranged along the extension direction of the second connecting rod 212. Since the first connecting rod 211 and the second connecting rod 212 are both inclined rods, the force on the inclined rods is mainly axial force, and the axial force component has the highest efficiency. Therefore, under the action of strong wind load, the first damper 410 can absorb the vibration caused by the strong wind, achieve structural stability, and prevent hidden cracks in the photovoltaic module 800.

[0068] See also Figure 4 In some embodiments, the photovoltaic mounting bracket further includes a connector 500; the end of the third connecting rod 213 close to the fourth connecting rod 214 is configured with a first mounting end 2131; the end of the fourth connecting rod 214 close to the third connecting rod 213 is configured with a second mounting end 2141; the connector 500 passes through the first mounting end 2131 and the second mounting end 2141, and is rotatably connected with the first mounting end 2131 and the second mounting end 2141. The connector 500 passes through the first mounting end 2131 and the second mounting end 2141, and is rotatably connected with the first mounting end 2131 and the second mounting end 2141, thereby realizing the rotatable connection between the third connecting rod 213 and the fourth connecting rod 214. Such a design makes the structure of the entire photovoltaic mounting bracket relatively simple.

[0069] See also Figure 5In some embodiments, the first mounting end 2131 includes at least two first mounting vertical plates 21311 spaced apart from each other; and a first mounting cavity 21312 is formed between two adjacent first mounting vertical plates 21311; the second mounting end 2141 is configured with a second mounting vertical plate 21411, and the second mounting vertical plate 21411 is at least partially accommodated in the first mounting cavity 21312; the connecting member 500 sequentially passes through the first mounting vertical plate 21311 and the second mounting vertical plate 21411, and is rotatably connected to the first mounting vertical plate 21311 and the second mounting vertical plate 21411. By forming the first mounting cavity 21312 between two adjacent first mounting vertical plates 21311, and disposing the second mounting vertical plate 21411 in the first mounting cavity 21312, and then sequentially passing the connecting member 500 through the first mounting vertical plate 21311 and the second mounting vertical plate 21411, the connection between the first mounting end 2131 and the second mounting end 2141 is more stable.

[0070] In one specific embodiment, the number of the first mounting vertical plates 21311 is three, and the number of the second mounting vertical plates 21411 is two. The connecting member 500 is a pin structure. Thus, the connection between the first mounting end 2131 and the second mounting end forms a structure of three (three first mounting vertical plates 21311) plugging two (two second mounting vertical plates 21411) pins (connecting member 500), which has good stability.

[0071] In some embodiments, the third connecting rod 213 and / or the fourth connecting rod 214 are telescopic rods. By setting the third connecting rod 213 and / or the fourth connecting rod 214 as telescopic rods, the heights of the two beam structures 210 arranged along the first direction in the second direction (such as Figure 2 and Figure 3 As shown), the installation angle of the photovoltaic assembly 800 is adjusted. In one specific embodiment, the third connecting rod 213 is a telescopic rod. In another specific embodiment, the fourth connecting rod 214 is a telescopic rod. In another specific embodiment, the third connecting rod 213 and the fourth connecting rod 214 are both telescopic rods. Specifically, the telescopic rod can be a hydraulic electric telescopic rod.

[0072] By using the third connecting rod 213 and / or the fourth connecting rod 214 as a telescopic rod, the length of the third connecting rod 213 or the fourth connecting rod 214 can be adjusted, so that the photovoltaic mounting bracket can be extended to Figure 2 or Figure 3 When in the state, the entire beam structure 210 can form a triangular structure, and the support stability of the entire beam structure 210 is high and it is not easy to deform.

[0073] In some of the embodiments, the photovoltaic mounting bracket includes a controller. When the third connecting rod 213 is a telescopic rod, the controller is electrically connected to the third connecting rod 213. When the fourth connecting rod 214 is a telescopic rod, the controller is electrically connected to the fourth connecting rod 214. When the third connecting rod 213 and the fourth connecting rod 214 are both telescopic rods, the controller is electrically connected to both the third connecting rod 213 and the fourth connecting rod 214. When it is necessary to adjust the installation height and installation angle of the photovoltaic assembly 800, the controller combines the intelligent sensor and the control algorithm to realize the automatic telescopic adjustment of the third connecting rod 213 and / or the fourth connecting rod 214, thereby responding to the position of the sun, seasonal changes or specific power generation needs in real time.

[0074] See also Figure 1-Figure 3 In some embodiments, the photovoltaic mounting bracket further includes a second support plate 600; the second support plate 600 is arranged opposite to the first support plate 100; the second support plate 600 is connected between two groups of beam structures 210 arranged at intervals along the first direction. By providing the second support plate 600, the structural stability of the entire beam assembly 200 is improved. Specifically, the first connecting rod 211 and the fourth connecting rod 214 are both rotatably connected to the second support plate 600.

[0075] In some embodiments, the number of the beam assemblies 200 is at least two groups, and the at least two groups of beam assemblies 200 are arranged at intervals along the third direction; the third direction is arranged at an angle to the first direction and the second direction; specifically, the third direction is Figure 6 By setting the number of the cross beam assembly 200 to at least two groups, the cross beam assembly 200 can provide better support stability for the first support plate 100. Figure 6 In one specific embodiment, the number of the beam assemblies 200 is two. Of course, in other embodiments, the number of the beam assemblies 200 may also be three, four, etc., and there is no special limitation on this, and it can be adaptively increased or decreased according to the size of the photovoltaic assembly 800.

[0076] See also Figure 6 In some embodiments, the photovoltaic mounting bracket further includes a back support assembly 700; the back support assembly 700 is installed between the two sets of beam assemblies 200, and the back support assembly 700 is connected to the first support plate 100. By providing the back support assembly 700, the support effect on the first support plate 100 is better, and thus the stability of the photovoltaic assembly 800 installed on the first support plate 100 is better.

[0077] See also Figure 6In some embodiments, the back support assembly 700 includes two oblique telescopic support members 710 disposed at an angle; and the other ends of the two oblique telescopic support members 710 away from each other are respectively rotatably connected to the two sets of beam assemblies 200. By providing two oblique telescopic support members 710 disposed at an angle, when the first support plate 100 moves along the second direction and rotates around its own rotation axis, the oblique telescopic support members 710 can be telescoped and support the first support plate 100, so that the stability of the first support plate 100 is better.

[0078] See also Figure 6 In some embodiments, the back support assembly 700 further includes a second damper 720; the second damper 720 is installed on at least one oblique telescopic support member 710. By providing the second damper 720, the wind resistance of the back support assembly 700 is improved, and the photovoltaic assembly 800 is more stable when installed on the first support plate 100.

[0079] The present application sets a first damper 410 and a second damper 720 so that the first damper 410 and the second damper 720 can absorb and reduce vibrations caused by wind, earthquakes or other external factors, protect the photovoltaic assembly 800 and the photovoltaic mounting bracket from damage, and extend their service life. At the same time, during the expansion and contraction process of the beam structure 210, the two dampers can help control the speed and force of folding and unfolding of the beam assembly 200 when switching between the folded state and the supporting state, and prevent instability or structural damage caused by rapid expansion and contraction. It also reduces safety risks caused by extreme weather or unexpected impacts; reduces energy loss caused by vibration, improves the power generation efficiency of the photovoltaic system; and reduces noise that may be generated during the expansion and contraction process.
