The photovoltaic support plate 201 is transmission-connected with a swing drive mechanism (not shown in the figure), and the swing drive mechanism is used to drive the photovoltaic support plate 201 to swing and maintain a set tilt angle when the box body 100 is opened. In this embodiment, the swing drive mechanism is connected to a control system, and the control system controls the swing drive mechanism to drive the photovoltaic support panel 201 to swing according to the sun's radiation angle, so as to adjust the tilt angle of the photovoltaic support panel 201 .

[0023] In this embodiment, after the photovoltaic frame 300 and the photovoltaic support panel 201 are fitted and supported, the photovoltaic frame 300 and the photovoltaic support panel 201 are non-rotatably connected, a first rotating shaft is fixed at one end of the photovoltaic support panel 201, and the first rotating shaft is rotatably installed on the inner wall of the second half box 106 to realize the rotational connection between one end of the photovoltaic support panel 201 and the second half box 106, a first external tooth 310 is provided on the outer wall of the first rotating shaft, and a retractable tooth 306 is movably provided on the photovoltaic frame 300.

[0024] In this embodiment, the photovoltaic frame 300 includes an outer frame 314 and a fixed plate 313 fixed in the outer frame 314. A telescopic plate 303 is movably installed in the outer frame 314. The telescopic plate 303 and the fixed plate 313 are in the same plane. The fixed plate 313 and the telescopic plate 303 are assembled to form a platform for placing photovoltaic panels. A strip groove is formed between the telescopic plate 303 and the fixed plate 313. A wedge block 301 is movably provided on the side of the photovoltaic frame 300 opposite to the photovoltaic support plate 201. In this embodiment, the wedge block 301 is installed in the strip groove, and a wedge surface is provided at one end of the telescopic plate 303 opposite to the fixed plate 313 to cooperate with the wedge block 301. One end of the telescopic plate 303 contacts and cooperates with the wedge block 301, and a first elastic member 302 is connected between the end of the telescopic plate 303 that contacts and cooperates with the wedge block 301 and the photovoltaic frame 300. In the initial state, the first elastic member 302 drives the telescopic plate 303 to push the wedge block 301. The wedge block 301 protrudes from the lower side of the photovoltaic frame 300 under the pushing action of the telescopic plate 303. When the photovoltaic frame 300 and the photovoltaic support plate 201 are in close contact with each other, the wedge block 301 is squeezed by the photovoltaic support plate 201 and retracts upward into the photovoltaic frame 300. Under the pushing action of the wedge block 301, the telescopic plate 303 moves in a direction away from the wedge block 301.

[0025] In this embodiment, an iris mechanism is provided in the photovoltaic frame 300, and the iris mechanism includes an inner gear ring 304, an idler wheel 305, and a transmission gear 309 coaxially fixedly connected to the inner gear ring 304. In this embodiment, the transmission gear 309 is fixedly connected to the inner gear ring 304 through a connecting rib extending along the radial direction of the inner gear ring 304, one end of the connecting rib is fixedly connected to the transmission gear 309, and the other end is fixedly connected to the inner gear ring 304. There are multiple connecting ribs, and the multiple connecting ribs are arranged radially with the transmission gear as the center. A mounting cylinder 312 is fixed on one side of the outer square frame 314, and the mounting cylinder 312 has an installation chamber, and the installation chamber is used to install the iris mechanism. The mounting cylinder 312 and the installation chamber are coaxial with the swing axis of the photovoltaic frame 300. The inner gear ring 304 is rotatably installed in the installation chamber, the idler wheel 305 is eccentrically arranged in the inner gear ring 304 and meshes with the inner gear ring 304 for transmission, the telescopic teeth 306 are inserted in the installation chamber along the radial direction of the installation chamber, and the outer wall of the installation cylinder 312 is provided with radial through holes for the telescopic teeth 306 to be telescopic, and the telescopic teeth 306 are provided with transmission racks 308, which mesh with the idler wheel 305. In this embodiment, a plurality of the idler wheels 305 and the telescopic teeth 306 are evenly spaced along the circumference of the inner gear ring 304, and the idler wheels 305 and the telescopic teeth 306 are arranged one by one. The end of the telescopic plate 303 away from the wedge block 301 is connected to a driving rack 307, and an escape notch for the driving rack 307 to pass through is provided on the outer wall of the mounting tube 312. The driving rack 307 passes through the escape notch and meshes with the transmission gear 309 located in the mounting tube 312. When the telescopic plate 303 moves in a direction away from the wedge block 301, the driving rack 307 drives the transmission gear 309 to rotate, and the inner gear ring 304 rotates synchronously with the transmission gear 309. The inner gear ring 304 drives the telescopic teeth 306 to extend outward through the corresponding idler gear 305, so that the telescopic teeth 306 mesh with the first outer teeth 310 on the first rotating shaft of the photovoltaic support panel 201, so as to achieve the anti-rotation cooperation between the photovoltaic frame 300 and the photovoltaic support panel 201.

[0026] In this embodiment, a photovoltaic baffle 200 is further provided in the box body 100, and a second rotating shaft is provided at one end of the photovoltaic baffle 200. The photovoltaic baffle 200 is rotatably mounted on the inner wall of the first half box 105 through the second rotating shaft to realize the swing connection between the photovoltaic baffle 200 and the first half box 105. The swing axis of the photovoltaic baffle 200 is the fourth axis, and the fourth axis is arranged parallel to the third axis, and the fourth axis and the third axis are symmetrical about the second axis. The second rotating shaft is provided with a second external tooth 311, and the second external tooth 311 is in driving engagement with the first external tooth 310. The photovoltaic baffle 200 and the photovoltaic support plate 201 are arranged symmetrically about the second axis. When the swing driving mechanism drives the photovoltaic support plate 201 to swing, the photovoltaic baffle 200 and the photovoltaic support plate 201 swing synchronously in opposite directions. In the present invention, the photovoltaic baffle 200 and the photovoltaic support plate 201 are symmetrical on the left and right, and the inclination angles of the photovoltaic baffle 200 and the photovoltaic support plate 201 are corresponding. The photovoltaic baffle 200 is located on one side of the photovoltaic frame 300 and can reflect sunlight to the photovoltaic panel on the photovoltaic frame 300, thereby improving the efficiency of the photovoltaic panel in collecting solar energy.

[0027] In this embodiment, a mounting hole is opened on the inner wall of the second half box 106, and the mounting hole is coaxially arranged with the swing axis of the photovoltaic frame 300. A friction wheel 104 is rotatably installed in the mounting hole. The friction wheel 104 is coaxial with the mounting hole and with the swing axis of the photovoltaic frame 300. The end face of the friction wheel 104 facing the outside of the mounting hole is a friction end face, and the friction end face is frictionally matched with the side wall of the photovoltaic frame 300. When the photovoltaic frame 300 swings, the photovoltaic frame 300 drives the friction wheel 104 to rotate.

[0028] A ratchet 102 is rotatably provided in the mounting hole, and a pawl 101 cooperating with the ratchet 102 is swingably provided on the inner wall of the mounting hole. The ratchet 102 is coaxially arranged with the friction wheel 104, and the ratchet 102 is located on the side of the friction wheel 104 that is away from the friction end face. A torsion spring 103 is connected between the ratchet 102 and the friction wheel 104, one end of the torsion spring 103 is fixedly connected to the ratchet 102, and the other end is fixedly connected to the friction wheel 104. When the photovoltaic frame 300 swings in a direction away from the photovoltaic support panel 201, the photovoltaic frame 300 drives the friction wheel 104 to rotate, and the pawl 101 prevents the ratchet 102 from rotating, so that the torsion spring 103 rotates and accumulates force. In an outdoor environment, when the photovoltaic frame 300 is affected by wind and swings in a direction away from the photovoltaic support panel 201, as the photovoltaic frame 300 swings in a direction away from the photovoltaic support panel 201, the photovoltaic frame 300 will drive the friction wheel 104 to rotate, while the ratchet 102 cannot rotate due to the blocking action of the pawl 101. The friction wheel 104 rotates relative to the ratchet 102 to allow the torsion spring 103 to accumulate force. When the wind disappears, under the action of the torsion spring 103, the photovoltaic frame 300 can swing toward the photovoltaic support panel 201 again and fit closely with the photovoltaic support panel 201 for support. In addition, since the photovoltaic frame 300 and the photovoltaic support panel 201 are in a state of non-rotation before separation, the telescopic teeth 306 on the photovoltaic frame 300 are meshed with the first external teeth 310 on the first rotating shaft. When the photovoltaic frame 300 begins to swing away from the photovoltaic support panel 201, the swing of the photovoltaic frame 300 can drive the photovoltaic support panel 201 to swing away from the photovoltaic frame 300 (i.e., downward) by a certain angle, which will reduce the inclination angle of the photovoltaic support panel 201. After the photovoltaic frame 300 returns to the position of being in contact with the photovoltaic support panel 201 under the action of the torsion spring 103, the inclination angles of the photovoltaic frame 300 and the photovoltaic support panel 201 are reduced to reduce the impact of wind on the photovoltaic frame 300 and the photovoltaic panel.

[0029] When a movable photovoltaic support of the present invention is used, the photovoltaic panel is fitted on the fixing plate 313 of the photovoltaic frame 300, and the second half box 106 of the box body 100 is fixedly installed at a set position, such as a roof, an open space, etc. At night and in rainy and snowy weather, the opening and closing driving mechanism drives the first half box 105 and the second half box 106 to buckle together, so that the box body 100 is closed, and then the photovoltaic frame 300 and the photovoltaic panel are hidden in the box body 100, thereby protecting the photovoltaic panel. During the day and when it is sunny, the opening and closing driving mechanism drives the first half box 105 to open, and the first half box 105 and the second half box 106 are unfolded to a 180° state, so that the box body 100 is fully opened, and the swing driving mechanism drives the photovoltaic support plate 201 to swing to a set tilt angle and remain at this position. The swing drive mechanism can control the swing drive mechanism according to the angle of sunlight to drive the photovoltaic support panel 201 to swing, so as to adjust the inclination angle of the photovoltaic support panel 201, thereby enabling the photovoltaic panel on the photovoltaic frame 300 to adapt to the angle of sunlight and improve the efficiency of the photovoltaic panel in collecting solar energy.

[0030] When there is wind outside, the photovoltaic frame 300 will be affected by the wind. If the wind makes the photovoltaic frame 300 fit more closely with the photovoltaic support plate 201, the inclination angle of the photovoltaic frame 300 does not need to be changed. When the photovoltaic frame 300 is affected by the wind and swings in the direction away from the photovoltaic support plate 201, the inclination angle of the photovoltaic frame 300 needs to be reduced. The specific adjustment process is: as the photovoltaic frame 300 swings in the direction away from the photovoltaic support plate 201, before the photovoltaic frame 300 and the photovoltaic support plate 201 are separated, the telescopic teeth 306 on the photovoltaic frame 300 are engaged with the first external teeth 310 on the first rotating shaft. When the photovoltaic frame 300 starts to swing in the direction away from the photovoltaic support plate 201, the swing of the photovoltaic frame 300 can drive the photovoltaic support plate 201 to swing in the direction away from the photovoltaic frame 300 (i.e., downward) by a certain angle, which will reduce the inclination angle of the photovoltaic support plate 201. And when the photovoltaic frame 300 swings in the direction away from the photovoltaic support plate 201, the photovoltaic frame 300 will drive the friction wheel 104 to rotate, and the ratchet 102 cannot rotate under the blocking action of the pawl 101, and the friction wheel 104 rotates relative to the ratchet 102 to store force in the torsion spring 103. When the wind disappears, under the action of the torsion spring 103, the photovoltaic frame 300 can swing toward the photovoltaic support plate 201 again and fit with the photovoltaic support plate 201. Since the inclination angle of the photovoltaic support plate 201 has been reduced at this time, after the photovoltaic frame 300 returns to the fit support with the photovoltaic support plate 201 under the action of the torsion spring 103, the inclination angles of the photovoltaic frame 300 and the photovoltaic support plate 201 are reduced, which can reduce the impact of wind on the photovoltaic frame 300 and the photovoltaic panel. At the same time, the reduction in the inclination angle of the photovoltaic support plate 201 will also reduce the inclination angle of the photovoltaic baffle 200 to avoid affecting the photovoltaic panel to collect solar energy.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
