[0039] A bottom bracket 2 is arranged on the top of the energy storage box body 1, and a support frame 201 is connected to one side edge of the bottom bracket 2 through a hinge. The support frame 201 is a rectangular frame structure consisting of a long side and a short side. A photovoltaic assembly 3 is arranged on the upper side of the support frame 201. A lateral sliding mechanism 4 is arranged on the two long sides of the support frame 201. The photovoltaic assembly 3 includes a photovoltaic panel 304 that slides parallel to the top of the lateral sliding mechanism 4. A linear sliding module is fixed to one side edge of the photovoltaic panel 304. The photovoltaic panel 304 is provided with a photovoltaic panel 4 306 connected to the linear sliding module 2 305 on the upper side thereof, a sliding convex strip is fixed to the upper edge of the photovoltaic panel 304 away from the linear sliding module 2 305, and a groove matching the sliding convex strip is provided to the lower edge of the photovoltaic panel 4 306 away from the linear sliding module 2 305, so that when the linear sliding module 2 305 drives the photovoltaic panel 4 306 to move, the photovoltaic panel 4 306 can slide smoothly on the photovoltaic panel 3 304;

[0040] A slide groove 308 is provided on the long side surface of the support frame 201, and a linear sliding module 301 is vertically fixed in the middle of the slide groove 308. Photovoltaic panels 302 are installed on both sides of the linear sliding module 301, and the photovoltaic panels 302 are fixed to the inner wall of the long side of the support frame 201; the upper side of the linear sliding module 301 is connected to the photovoltaic panel 2 303, and the photovoltaic panel 2 303 is slidably connected to the slide groove 308, and a pressure plate 307 is fixed to the upper side of the photovoltaic panel 4 306 close to the linear sliding module 2 305, and the pressure plate 307 is in contact with the upper side of the linear sliding module 2 305, and the pressure plate 307 is used to align the light The sliding of photovoltaic panel four 306 is guided; the sliding groove 308 can limit the sliding of photovoltaic panel two 303 to ensure its moving stability; the linear sliding module one 301 and the linear sliding module two 305 are composed of a linear track, a servo motor, a screw and a mounting block. This is the prior art. The servo motor is installed at one end of the linear track, and the output end of the servo motor is connected to the screw inside the linear track. The screw and the mounting block are threadedly connected, wherein the mounting block of the linear sliding module one 301 is docked with the photovoltaic panel two 303, and the mounting block of the linear sliding module two 305 is docked with the photovoltaic panel four 306.

[0041] In specific implementation, when it is necessary to unfold the photovoltaic component 3 to convert solar energy into electrical energy, the servo motor of the linear sliding module 301 is started to rotate forward to drive the screw inside the linear track to rotate, so that the rotating screw drives the mounting block to slide linearly to drive the photovoltaic panel 2 303 to slide along the slide groove 308, so that the photovoltaic panel 1 302 and the photovoltaic panel 2 303 complete the horizontally staggered extension movement. Conversely, when the servo motor of the linear sliding module 301 is started to reverse, the photovoltaic panel 1 302 and the photovoltaic panel 2 303 can be stacked together to complete storage.

[0042] See also Figure 7 , Figure 8 , Fig.10 and Fig.11The lateral sliding mechanism 4 includes a slide seat 401 fixed to the inner wall of the long side of the support frame 201, and the slide seat 401 is internally slidably connected to the guide rail 402. The surface of the long side of the support frame 201 close to the slide seat 401 is provided with a convex groove, and the convex groove is used for sliding guidance of the guide rail 402. A tension spring 403 is fixed between the slide seat 401 and the guide rail 402. A rotating block 404 is fixed at the bottom of the diagonal end of the photovoltaic panel three 304 away from the rotation axis, and the rotating block 404 is slidably connected to the inside of the guide rail 402; when two adjacent photovoltaic panels three 304 are adjusted from the storage state to the horizontal flip extension state, the rotating block 404 at a corner of the bottom of the photovoltaic panel three 304 will squeeze the guide rail 402 and export the surface of the support frame 201. The convex notch ensures that when two adjacent photovoltaic panels 304 rotate around the rotation axis at one corner, the rotating block 404 at the other corner of the photovoltaic panel 304 can slide horizontally, and then the photovoltaic panel 304 can be tightened by the docking of the rotating block 404 and the guide rail 402. At the same time, the guide rail 402 can pull the tension spring 403 between the slide 401 and the guide rail 402 when leading out of the convex notch. Therefore, when the two adjacent photovoltaic panels 304 are reset and flipped, the tension spring 403 is reset, so that the tension spring 403 can pull the guide rail 402 to retract into the slide 401; when the photovoltaic component 3 is not extended and opened, it can ensure that the guide rail 402 is retracted into the energy storage box body 1 without affecting the aesthetics of the energy storage box body 1.

[0043] See also Figure 3-Figure 5 , Figure 7-Figure 14A guide groove 202 is provided on the short side of the support frame 201. The guide groove 202 is composed of an I-shaped groove and a strip-shaped opening. The width of the strip-shaped opening is greater than the diameter of the column 507. The guide groove 202 allows the column 507 to move through the strip-shaped opening, so that the column 507 is not hindered when moving. A driving mechanism 5 is provided on one of the short sides of the support frame 201. The driving mechanism 5 includes two groups of driving rods 501 movably connected to the surface of the short side of the support frame 201. Two screw rods 502 are movably connected between the two short sides of the support frame 201. A push-pull member 506 is sleeved on the screw rod 502. A column 507 is fixed to one end of the push-pull member 506. Two adjacent photovoltaic panels 304 are movably connected through a rotating shaft, and the bottom end of the rotating shaft is movably connected to the upper end of the column 507. Then, the inner wall of the long side of the support frame 201 is provided with a flip mechanism 7, and the flip mechanism 7 includes an anti-deflection frame 701 fixed to the inner wall of the long side of the support frame 201, and a worm 702 is connected to the side of the support frame 201 close to the anti-deflection frame 701, and a transmission rod 6 is connected between the driving rod 501 and the worm 702, and the two ends of the transmission rod 6 are respectively connected to the driving rod 501 and the worm 702 through universal joints, so that the driving rod 501 can drive the inclined transmission rod 6 to drive the worm 702 to rotate when rotating, and the inner wall of the long side of the support frame 201 is connected to a worm wheel 703 meshing with the worm 702 through a bearing seat, and the outer side of the worm wheel 703 is connected to a support arm 704 sliding with the anti-deflection frame 701, and the upper side of the bottom bracket 2 is fixed with an inclined rail seat 707 connected to the support arm 704;

[0044] The two screw rods 502 are arranged with opposite thread rotation directions. When the two screw rods 502 rotate in the same direction, the two screw rods 502 with opposite thread rotation directions can drive the two misplaced push-pull members 506 to move closer to or away from each other. Synchronous wheels are fixed to the outer side of one end of the screw rod 502 close to the driving rod 501 and the outer side of one end of the driving rod 501. The outer side of the synchronous wheels of the two driving rods 501 is sleeved with a synchronous belt 1 503. The outer side of the synchronous wheel between the driving rod 501 and the screw rod 502 is sleeved with a synchronous belt 2 504. A motor 505 connected to one of the driving rods 501 is installed on the outer side of the support frame 201.

[0045] The push-pull member 506 is composed of a threaded sleeve and an I-beam welded together. The threaded sleeve of the push-pull member 506 is threadedly connected to the screw rod 502. The I-beam of the push-pull member 506 is slidably connected to the I-groove of the guide groove 202. The I-beam of the push-pull member 506 is vertically fixed to the column 507. Two parallel support rods are fixed to the inner wall of the support frame 201, and the two support rods slide with the I-beams of the two push-pull members 506 respectively. The I-beams of the push-pull member 506 can be supported respectively by the two parallel support rods, ensuring that the push-pull member 506 has stability when supporting the photovoltaic panel three 304 through the column 507.

[0046] In specific implementation, when the photovoltaic assembly 3 is in the storage state, the first side edges of the two adjacent photovoltaic panels 304 close to the rotation axis are in a close placement state, and the second side edges of the two adjacent photovoltaic panels 304 close to the rotation axis are in a horizontally opened state. By starting the motor 505 of the driving mechanism 5 to drive one of the driving rods 501 to rotate forward, the other driving rod 501 connected to the synchronous belt 1 503 follows and rotates forward, and the synchronous belt 2 504 transmits the power of the driving rod 501 to the screw rod 502, so that the two screw rods 502 are threadedly driven with the threaded sleeves of the push-pull member 506 during forward rotation, so as to drive the two misaligned push-pull members 506 away from each other, so that the push-pull member 506 drives the column 507 to slide linearly along the support rod through the I-beam, so that the rotating block 404 on the photovoltaic panel 304, which is diagonally arranged with the rotation axis, slides in the guide rail 402, and then the column 507 can push the rotation axis of the two adjacent photovoltaic panels 304 to move toward the outside of the support frame 201;

[0047] When the I-beam of the push-pull member 506 drives the column 507 at one end to move out of the guide groove 202, the push-pull member 506 will drive the two adjacent photovoltaic panels 304 to continue to flip, until the two adjacent photovoltaic panels 304 complete a 90° flip around the rotation axis, so that the first side edges of the two adjacent photovoltaic panels 304 close to the rotation axis are horizontally opened, and at the same time, the second side edges of the two adjacent photovoltaic panels 304 close to the rotation axis are closely placed, and the two adjacent photovoltaic panels 304 are horizontally flipped and opened to the extreme position, and the push-pull member 506 cooperates with the column 507 to support the two adjacent photovoltaic panels 304 and the photovoltaic panel 4 306 on the photovoltaic panel 304, and then, by starting the photovoltaic panel 3 The linear sliding module 2 305 on the side of 304 drives the screw inside the linear track to rotate through the servo motor, so that the rotating screw drives the mounting block to slide linearly to drive the photovoltaic panel 4 306 and the photovoltaic panel 3 304 to extend and misalign, so that the photovoltaic panel 4 306 and the photovoltaic panel 3 304 can be illuminated at the same time after being extended and placed. At this time, the photovoltaic panel 3 304 and the photovoltaic panel 4 306 in the storage state can be flipped and moved from the upper side of the support frame 201 to the side of the support frame 201 through the positive movement of the driving mechanism 5. By adopting the flipping extension at a horizontal angle, the photovoltaic panel 3 304 and the photovoltaic panel 4 306 can greatly reduce the occupation of the top space of the energy storage box body 1;

[0048] On the contrary, when the driving mechanism 5 moves in the reverse direction, the photovoltaic panel three 304 and the photovoltaic panel four 306 in the extended and opened state can be flipped and moved from the side of the support frame 201 to the upper side of the support frame 201 for storage and protection.

[0049] See also Figure 7 , Fig. 9 , Fig.10 , Figure 12-14 The upper and lower surfaces of the worm wheel 703 are provided with an inner circular slideway 703a, an extrusion slideway 703b and an outer circular slideway 703c. The inner circular slideway 703a and the outer circular slideway 703c are a "C"-shaped structure distributed in concentric circles. One end of the inner circular slideway 703a and one end of the outer circular slideway 703c are connected to the extrusion slideway 703b. The central axis of the inner circular slideway 703a, the outer circular slideway 703c and the worm wheel 703 are coaxially arranged;

[0050] A U-shaped opening is opened on one side of the support arm 704, and a bayonet pin 705 is symmetrically fixed to the end of the U-shaped opening of the support arm 704. The worm 702 is inserted into the middle of the U-shaped opening of the support arm 704, and the worm 702 and the inner wall of the U-shaped opening of the support arm 704 do not contact each other. The bayonet pin 705 is docked with the inner circular slideway 703a, and a guide wheel 706 is connected to the side of the support arm 704 away from the worm wheel 703, and the guide wheel 706 is inserted into the inclined rail seat 707.

[0051] In specific implementation, when the motor 505 of the driving mechanism 5 drives the driving rod 501 to realize positive rotation, the driving rod 501 can drive the worm 702 to rotate forwardly through the transmission rod 6, so that the worm 702 is positively meshed with the worm wheel 703 to drive the worm wheel 703 to rotate forwardly, so that the worm wheel 703 will slide with the pin 705 at one end of the support arm 704 through the inner circular slideway 703a on the surface when rotating forward. When the worm wheel 703 rotates to the extrusion slideway 703b to extrude the pin 705, the extrusion slideway 703b will push the pin 705 to move into the outer circular slideway 703c. At this time, the support arm 704 will move in a directional manner in the anti-bias frame 701, and the support arm 704 will be squeezed and rolled with the inclined rail seat 707 through the guide wheel 706. Since a hinge is used between the bottom bracket seat 2 and the support frame 201 The rotatable connection means that when the guide wheel 706 at one end of the support arm 704 moves along the inclined rail seat 707 and drives the support arm 704 to rise in height, the anti-bias frame 701 drives the support frame 201 to rotate upward around the hinge on one side of the bottom bracket seat 2, and the first self-locking of the angular rotation of the support frame 201 is achieved through the meshing transmission of the worm 702 and the worm wheel 703, and then the second self-locking of the angular rotation of the support frame 201 is achieved through the docking of the outer circular slideway 703c with the latch 705 on the support arm 704, so that the opening angle of the bottom bracket seat 2 and the support frame 201 is double-self-locked, ensuring that the photovoltaic module 3 has high efficiency and stability when tilting, and at the same time ensuring that the two adjacent photovoltaic panels 304 can synchronously adjust the inclination of the photovoltaic module 3 when they are horizontally flipped and extended;

[0052] On the contrary, when the motor 505 of the driving mechanism 5 drives the driving rod 501 to achieve reverse rotation, the worm wheel 703 will move in the opposite direction through the support arm 704 and the inclined rail seat 707, so that the support frame 201 rotates back to fit with the bottom bracket seat 2, and the first self-locking of the angular rotation of the support frame 201 is achieved through the meshing transmission of the worm 702 and the worm wheel 703, and then the second self-locking of the angular rotation of the support frame 201 is achieved through the docking of the inner circular slide 703a with the latch 705 on the support arm 704, so that the bottom bracket seat 2 and the support frame 201 are stably fitted and abutted and will not be accidentally opened.

[0053] See also Figure 5 and Figure 6 A rotary drive motor 8 is fixed on the top of the energy storage box body 1, and the top output end of the rotary drive motor 8 is fixed to the lower surface of the bottom support seat 2. By arranging the rotary drive motor 8 between the top of the energy storage box body 1 and the lower surface of the bottom support seat 2, and controlling the rotation angle of the rotary drive motor 8 through a program, the photovoltaic component 3 on the bottom support seat 2 can be driven to rotate and change its orientation, thereby adapting to the position of the sun.

[0054] In summary, the photovoltaic assembly 3 is driven to complete horizontal extension and opening by starting the driving mechanism 5, so that the photovoltaic panel 1 302, the photovoltaic panel 2 303, the photovoltaic panel 3 304 and the photovoltaic panel 4 306 are extended to the surrounding areas on the top of the energy storage box body 1, and during the extension, the self-locking and adjustment of the flip mechanism 7 can drive the photovoltaic assembly 3 on the support frame 201 to be limited to a specific tilt state, and the rotation direction of the photovoltaic assembly 3 is changed by program-controlled rotary drive motor 8 to ensure that the photovoltaic assembly 3 converts light energy into electrical energy, and the photovoltaic assembly 3 transmits the electrical energy to the battery pack of the energy storage assembly 101 for energy storage under the control of the photovoltaic controller, and then is connected to the external electrical equipment directly through the battery pack or after conversion through the inverter, so as to provide energy to the external electrical equipment, and the battery management system is used to manage and monitor the battery pack in real time.
