[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 4As shown, an embodiment of the present invention provides a photovoltaic bracket, which includes a mounting frame 10, a photovoltaic frame 20 and a folding assembly 30. The photovoltaic frame 20 can be movably arranged on the mounting frame 10. The photovoltaic bracket has a folded state and an unfolded state. In the process of switching the photovoltaic bracket from the folded state to the unfolded state, the photovoltaic frame 20 gradually moves away from the mounting frame 10. The folding assembly 30 includes a first slider 31, a second slider 32, a first swing rod 33, a second swing rod 34 and a driving member 35. One end of the first swing rod 33 is hinged to the first slider 31, and the second swing rod 34 is hinged to the first slider 31. One end of the rod 34 is hinged to the second slider 32, wherein the first slider 31 and the second slider 32 can be relatively movably arranged on the photovoltaic frame 20, and the driving member 35 is arranged on the mounting frame 10, and / or the first slider 31 and the second slider 32 can be relatively movably arranged on the mounting frame 10, and the driving member 35 is arranged on the photovoltaic frame 20, and the driving member 35 is drivingly connected to the second end of the first swing rod 33 and the second end of the second swing rod 34 to drive the first swing rod 33 and the second swing rod 34 to swing, so that the photovoltaic bracket switches between a folded state and an unfolded state.

[0029] The photovoltaic bracket provided in this embodiment is used, and the photovoltaic bracket includes a mounting frame 10, a photovoltaic frame 20 and a folding assembly 30. The driving member 35 is used to drive the first swing arm 33 and the second swing arm 34 to swing, so that the photovoltaic bracket is switched to a folded state to improve the portability of the photovoltaic bracket during transportation. The photovoltaic bracket is placed in a temporary power use scenario so that the mounting frame is located at the installation position, and the photovoltaic panel is installed on the photovoltaic frame 20. The driving member 35 is used to drive the first swing arm 33 and the second swing arm 34 to swing, so that the photovoltaic bracket is switched to an unfolded state to complete the installation of the photovoltaic bracket. Therefore, the driving member 35 is used to switch the photovoltaic bracket between the folded state and the unfolded state, which can improve the portability of the photovoltaic power generation device and facilitate installation and disassembly.

[0030] In this embodiment, the photovoltaic support further includes a locking structure, which is disposed between the mounting frame 10 and the photovoltaic frame 20. The locking structure has a locked state and an unlocked state. When the locking structure is in the locked state, the locking structure limits the movement of the photovoltaic frame 20 relative to the mounting frame 10. When the locking structure is in the unlocked state, the locking structure allows the photovoltaic frame 20 to move relative to the mounting frame 10. By disposing the locking structure between the mounting frame 10 and the photovoltaic frame 20, the movement of the photovoltaic frame 20 relative to the mounting frame 10 is limited by the locking structure in the locked state, so that the photovoltaic frame 20 is prevented from moving relative to the mounting frame 10 under a force other than the driving force provided by the driving member 35, thereby improving the structural reliability of the photovoltaic support.

[0031] In this embodiment, the locking structure includes a fixed rack, a first movable tooth and a second movable tooth. The fixed rack extends along the arrangement direction of the first slider 31 and the second slider 32. The fixed rack, the first slider 31 and the second slider 32 are all arranged on the photovoltaic frame 20, and / or the fixed rack, the first slider 31 and the second slider 32 are all arranged on the mounting frame 10. The first movable tooth is movably arranged on the first slider 31, and the second movable tooth is movably arranged on the second slider 32. When the locking structure is in a locked state, the first movable tooth and the second movable tooth are both engaged with the fixed rack, and when the locking structure is in an unlocked state, the first movable tooth and the second movable tooth are both separated from the fixed rack. By changing the meshing state of the first movable tooth and the fixed rack and the meshing state of the second movable tooth and the fixed rack, the locking structure can be switched between the locked state and the unlocked state, thereby simplifying the structure of the locking structure. By limiting or allowing the movement of the first slider 31 and the second slider 32, the swing of the first swing arm 33 and the second swing arm 34 are indirectly limited, thereby indirectly limiting the movement of the photovoltaic rack 20 relative to the mounting rack 10. The photovoltaic rack 20 can be fixed at any angle and height for operation, and the photovoltaic rack can support its own weight, resist strong winds and maintain stability. The locking structure is switched to the unlocked state, at which time the photovoltaic rack can switch between the unfolded state and the folded state, and by changing the swing angle of the first swing arm 33 and the second swing arm 34, the height and angle of the photovoltaic rack 20 can also be adjusted.

[0032] In this embodiment, the locking structure further includes a first reset member and a second reset member, wherein the first reset member is disposed between the first movable tooth and the first slider 31 to apply a reset force to the first movable tooth close to the fixed rack, and the second reset member is disposed between the second movable tooth and the second slider 32 to apply a reset force to the second movable tooth close to the fixed rack. The use of the first reset member and the second reset member can facilitate the first movable tooth and the second movable tooth to be reset to a position meshing with the fixed rack, and prevent the meshing failure caused by external forces from interfering with the external environment.

[0033] In this embodiment, the photovoltaic bracket further includes a control member, which is respectively connected to the drive member 35 and the locking structure signal to control the operation of the drive member 35 and control the locking structure to switch between the locked state and the unlocked state. The control member is used to control the operation of the drive member 35 and control the locking structure to switch between the locked state and the unlocked state, which can facilitate the user's remote control operation, simplify the user's operation, and save effort and convenience.

[0034] In this embodiment, the photovoltaic bracket further includes a camera 40, which is arranged on the photovoltaic bracket 20, and the control component is connected to the camera 40 signal to control the driving component 35 and the locking structure according to the shooting results of the camera 40. After the photovoltaic bracket is placed at the installation position, the camera 40 is used to scan the placement scene of the photovoltaic bracket, and the control component determines the topography according to the shooting results of the camera 40, and then the control component controls the locking structure to switch to the unlocked state, and the driving component 35 drives the photovoltaic bracket to switch to the unfolded state, and the control component controls the driving component 35 to drive the first swing arm and the second swing arm to swing according to the local latitude, time and weather conditions, so as to adjust the height and angle of the photovoltaic bracket 20 by itself to maximize the power generation.
