[0002] With the continuous enhancement of global energy shortage and environmental protection awareness, distributed photovoltaic power generation technology has developed rapidly. More and more families hope to use the residential space for photovoltaic power generation to achieve energy self-sufficiency and reduce electricity costs. However, the existing balcony photovoltaic power generation systems have problems such as large space occupation, low intelligence level, and susceptibility to weather conditions, which limit their wide application.

[0003] The current balcony photovoltaic power generation systems on the market mainly adopt the fixed bracket installation method, and the common solutions include:

[0004] Balcony railing installation: The photovoltaic modules are fixed on the balcony guardrail. The structure is simple, but there are safety hazards and it does not have the intelligent adjustment function.

[0005] Floor placement installation: The photovoltaic modules are directly placed on the balcony floor, occupying the family space and affecting daily life.

[0006] Fixed angle installation: The inclination angle of the photovoltaic panel cannot be adjusted according to the sun angle, resulting in low power generation efficiency and being greatly affected by the environment.

[0007] Although the existing balcony photovoltaic technologies provide a certain power generation capacity, there are still the following problems:

[0008] Space occupation: The traditional installation methods occupy the balcony floor or guardrail, affecting the family activity space.

[0009] Limited power generation efficiency: The fixed-angle photovoltaic panels cannot be adjusted according to the sun position, resulting in non-optimal power generation angles and reducing the power generation efficiency.

[0010] Lack of intelligent control: It cannot automatically adjust the angle or retract / extend the photovoltaic panels according to the light and weather conditions, is easily affected by bad weather such as strong winds, rain and snow, and shortens the equipment life.

[0011] Single function: It is only used for power generation, lacks additional functions such as sunshading and lighting, and fails to maximize the use value of the family balcony. Summary of the Invention

[0058] Figure 1 is a top view of an intelligent photovoltaic sunshade Figure 2 is Figure 1 a side view of Figure 3 is Figure 1Schematic diagram of the internal structure, including a housing 1 with an opening on one side for the photovoltaic module 2 to extend or retract, and capable of ceiling installation; the photovoltaic module 2 for residential power generation.

[0059] The top of the housing 1 of the present invention has a planar structure, and a hoisting assembly 6 is provided, which can be installed in the form of hoisting at the balcony or the ceiling of the building, without occupying ground space. Especially in a family, when it is hung on the ceiling of the balcony, it does not occupy the balcony floor space, releases more activity space, and does not affect family activities. The hoisting assembly 6 can be selected in ways such as eyebolts, expansion wires, etc., and is not limited here.

[0060] The present invention provides a housing 1 with an opening, and the photovoltaic module 2 can extend or retract from this opening. When fully extended, as shown in Figure 1 and Figure 2 shown, it is convenient for sunshading and photovoltaic power generation. When fully retracted, the photovoltaic module 2 can completely enter the interior of the housing 1 without occupying space after storage.

[0061] The present invention further includes: a telescopic assembly 3, whose fixed end is arranged inside the housing 1, and whose moving end is always located inside the housing 1; a rotating assembly 4, which is connected to the moving end of the telescopic assembly 3 and is hinged to the photovoltaic module 2 through a connecting rod 414; the telescopic assembly 3 can drive the rotating assembly 4 and the photovoltaic module 2 to move to control the length of the photovoltaic module 2 extending out of the housing 1; the rotating assembly 4 can drive the photovoltaic module 2 to rotate to control the angle of the photovoltaic module 2 after extending out of the housing 1; wherein, the length and angle of the photovoltaic module 2 are used to maximize sunshading and maximize power generation.

[0062] Figure 3 The connection relationship among the telescopic assembly 3, the rotating assembly 4 and the photovoltaic module 2 is shown in Figure 4 is a schematic diagram of the telescopic assembly, Figure 5 is a schematic diagram of the connection between the rotating assembly and the photovoltaic module, Figure 6 is Figure 5 a partial enlarged schematic diagram, Figure 7 is an exploded schematic diagram of the acting plate and the connecting piece.

[0063] As shown in Figure 4As shown, the telescopic assembly 3 includes a fixed end and a mobile end. The fixed end includes a first motor 301, a long shaft 302, and at least one transmission rod 303. The first motor 301, the long shaft 302, and the at least one transmission rod 303 are drivingly connected. The mobile end includes a synchronous belt 306 and a moving strip 310. The synchronous belt 306 is laid on the transmission rod 303 and is driven by the first motor 301. The moving strip 310 is connected to the synchronous belt 306 and reciprocates with the synchronous belt 306. The moving strip 310 extends to two opposite inner walls of the housing 1 respectively and is provided with an action plate 314. The action plate 314 is also connected to the inner wall of the housing 1 through a pulley 313 and a first slide rail 312. Thus, when the first motor 301 rotates forward and backward, it can drive the action plate 314 to reciprocate. The action plate 314 is used to mount the rotating assembly 4.

[0064] In the present invention, the telescopic assembly 3 is always located inside the housing 1. The first motor 301 drives the long shaft 302 to rotate. The long shaft 302 is equipped with two transmission rods 303 to maintain stability. The first motor 301 is fixed on the support frame 105 through a first mounting plate 308. The transmission rods 303 are fixed on the support frame 105 through a second mounting plate 309 and remain stationary with respect to the motor 301 and the long shaft 302. Rear synchronous wheels 304 and front synchronous wheels 305 are respectively arranged at both ends of the transmission rod 303. The synchronous belt 306 is arranged on the rear synchronous wheels 304 and the front synchronous wheels 305. The rear synchronous wheel 304 is also connected to the long shaft 302 and is used to drive the synchronous belt 306 to run, thereby driving the moving strip 310 to move forward and backward. When moving forward, it can drive the photovoltaic module 2 to extend outwards, and when moving backward, it can drive the photovoltaic module 2 to retract backward.

[0065] In the present invention, the action plate 314 is provided. The action plate 314 is connected to the pulley 313. The pulley 313 cooperates with the first slide rail 312. The first slide rail 312 is fixed to the inner wall of the housing 1, that is, Figure 8 the inner wall of the side sealing plate 104. When the first motor 301 works, it drives the action plate 314 to move forward and backward. Since the rotating assembly 4 is mounted on the action plate 314, it can drive the rotating assembly 4 to move forward and backward. And because the photovoltaic module 2 is connected to the rotating assembly 4, it can also drive the photovoltaic module 2 to move forward and backward to realize extension and retraction.

[0066] In the present invention, the telescopic assembly 3 is used to realize the extension and retraction of the photovoltaic module 2, and the form of motor drive is used to control the telescopic movement. The motor can be a servo motor, which has high precision and is convenient to control.

[0067] Such as Figure 5 and Figure 6As shown in the figure, the rotating assembly 4 includes a connecting piece 404, a rack 405, a gear 413, and a rotating shaft 411. The connecting piece 404 is connected to the actuating plate 314 through a slider 403 and a second sliding rail 402. The rack 405 is fixed to the connecting piece 404. The gear 413 is installed on the rotating shaft 411. The gear 413 meshes with the rack 405. The end of the rotating shaft 411 is installed on the actuating plate 314. The rotating shaft 411 is connected to a second motor 410. The rotating shaft 411 can drive the gear 413 to rotate, thereby causing the rack 405 and the connecting piece 404 to move back and forth. The connecting piece 404 is used to hingedly connect one end of the connecting rod 414. The other end of the connecting rod 414 is hinged to the photovoltaic module 2. The photovoltaic module 2 is also connected to the actuating plate 314 through a hinge 415. Thus, when the connecting piece 404 moves back and forth, it can drive the connecting rod 414 to move, so that the photovoltaic module 2 rotates to different angles.

[0068] In the present invention, the connecting piece 404 is fixedly connected to the slider 403, and the second sliding rail 402 is fixedly connected to the actuating plate 314. The slider 403 cooperates with the second sliding rail 402. Thus, the connecting piece 404 can move with the actuating plate 314 as a base plate. When the second motor 410 works, the second motor 410 drives the rotating shaft 411 to rotate, thereby driving the gear 413 to rotate. Thus, under the meshing action, the rack 405 is driven to move. The rack 405 is fixed to the connecting piece 404 and moves more smoothly under the cooperation of the slider 403 and the second sliding rail 402.

[0069] In the present invention, the photovoltaic module 2 and the rotating assembly 4 are connected by a hinge 415 and a connecting rod 414, and both are hinged connections. When the connecting piece 404 moves backward, it pulls the connecting rod 414 to move backward. Under the action of the hinge 415, the connecting rod 414 pulls down the photovoltaic module 2 to change the angle of the photovoltaic module 2. The angle of the photovoltaic module can change from 0° to 90° to adapt to different lighting angles during the day and achieve the maximum efficiency of sunshading and power generation.

[0070] In the present invention, the actuating plate 314 is used as a slider cooperating with the first sliding rail 312 in the telescopic assembly 3 and also as a base plate in the rotating assembly 4. As Figure 7As shown, the action plate 314 includes a main plate 3141, a slide rail mounting plate 3142 fixed to the lower end of the main plate 3141, and a connecting angle code 3145 fixed to the end of the main plate 3141. The main plate 3141 is used to connect the pulley 313. The slide rail mounting plate 3142 is used to mount the second slide rail 402. The connecting angle code 3145 is used to mount the hinge 415. The main plate 3141 is further provided with a first mounting hole 3143 and a second mounting hole 3144. The first mounting hole 3143 is used to mount the moving strip 310. The second mounting hole 3144 is used to mount the rotating shaft 411.

[0071] In the present invention, the main plate 3141 of the motherboard is parallel to the side sealing plate 104 of the housing 1, which is convenient for cooperating with the first slide rail 312 fixed on the side sealing plate 104. The first mounting hole 3143 on the main plate 3141 can mount the moving strip 310, keeping the main plates 3141 on both sides and the moving strip 310 as a whole, which is convenient for controlling the telescopic movement of the telescopic assembly 3. The second mounting hole 3144 is used to mount the rotating shaft 411 and is used as part of the rotating assembly. The rotating shaft 411 of the second motor 410 is directly mounted on the main plate 3141 through a pedestal bearing, which is convenient for forming an integral whole with the common movement of the rotating assembly 4 and the telescopic assembly 3. In the present invention, the slide rail mounting plate 3142 is located at the lower part, so that the connecting piece 404 is located at the lower part, and thus the rear end of the connecting rod 414 is low and the front end connecting the position of the photovoltaic module is high, forming a triangular structure with the hinge 415, which is convenient for adjusting the angle of the photovoltaic module 2.

[0072] As Figure 7 shown, the connecting piece 404 includes a long piece 4041 and a short piece 4042 extending from the long piece 4041. The short piece 4042 is provided with a hinge hole 4043, and the hinge hole 4043 is used to connect the connecting rod 414. The long piece 4041 is used to fix the rack 405 and is fixedly connected to the slider 403.

[0073] In the present invention, the connecting piece 404 presents an L-shaped structure, so that the position of the short piece 4042 is low, and thus the rear end position of the connecting rod 404 is low, which is convenient for adjusting the angle of the photovoltaic module 2.

[0074] Figure 8It is a schematic diagram of the outer shell decomposition. The outer shell 1 includes a frame 101, a top sealing plate 102, a bottom sealing plate 103, and side sealing plates 104. The frame 101 is provided with a support frame 105, and the support frame 105 is used to install the transmission rod 303. The top sealing plate 102 is provided with a hoisting assembly 6 for hoisting. The front and rear ends of the bottom sealing plate 103 are respectively provided with a front arc panel 1033 and a rear arc panel 1031. There is a gap between the front arc panel 1033 and the top sealing plate 102, and this gap serves as an opening for the photovoltaic module 2 to extend or retract from the outer shell 1. The rear arc panel 1031 is provided with a seal 1032 and is connected to the top sealing plate 102. The side sealing plates 104 are used to fix the first slide rail 312. The support frame 105 is also installed with a support bar 106, the support bar 106 is installed with a light strip 5, and the bottom sealing plate 103 is provided with a light-transmitting strip 1034, and the light-transmitting strip 1034 is aligned with the light strip 5.

[0075] In the present invention, an opening is provided at the front part of the outer shell 1, and the rest of the positions are closed. Only the photovoltaic module 2 can extend or retract from the front opening. And a small seal is provided at the front end of the photovoltaic module 2, which can block the opening with the small seal after the photovoltaic module 2 is completely retracted, forming a closed outer shell 1 to prevent dust from entering. The frame 101 of the present invention is a three-dimensional square frame structure, and the top, bottom, left, and right of the square frame are respectively closed by the top sealing plate 102, the bottom sealing plate 103, and the side sealing plates 104. The front and rear of the bottom sealing plate 103 are arc-shaped panels, which can close the front and rear ends of the square frame and leave an opening at the front end. The square frame is used as a load-bearing frame and also as a receiving cavity for the telescopic assembly 3, the rotating assembly 4, and the photovoltaic module 2. The telescopic assembly 3 and the rotating assembly 4 are both set relying on the square frame.

[0076] Figure 9 It is a schematic diagram of the support bar provided with a light strip. Figure 10 It is Figure 1 The bottom view of it can show the position of the light-transmitting strip 1034 to form an illumination or warning effect, with good aesthetics and also providing a night lighting effect.

[0077] Figure 11 It is a schematic diagram of the frame of the photovoltaic module. The photovoltaic module 2 includes a frame and photovoltaic panels, and the photovoltaic panels are installed on the frame. The frame includes a long side frame 201, a short side frame 202, and a reinforcing bar 203. The long side frame 201 is also provided with a long profile 204, and the long profile 204 is used to connect the hinge 415. The long side frame 201 is also provided with a connecting ear 205, and the connecting ear 205 is used to hinge the connecting rod 414.

[0078] The present invention also provides an overflow port at the short side frame 202 on the front side for discharging rainwater to prevent water accumulation.

[0079] The present invention further includes a sensing component for monitoring the angle parameter of the photovoltaic module 2, and the angle parameter is used to control the working state of the photovoltaic module 2.

[0080] Specifically, the sensing component includes a wind-sensing gyroscope, and the wind-sensing gyroscope is arranged on the photovoltaic panel. The wind-sensing gyroscope is installed in the installation groove 207 of the front short side frame 202. Under normal circumstances, the up-and-down swing of the photovoltaic panel monitored by the wind-sensing gyroscope should not exceed 5°. When in a bad situation, if the up-and-down swing of the wind-sensing gyroscope exceeds 5° and lasts for more than three times continuously, the system automatically retracts the photovoltaic panel.

[0081] It also includes a rotary encoder disc and a photoelectric inductor for monitoring the angle parameter of the gear 413; the rotary encoder disc is fixed to the rotating shaft 411, and the photoelectric inductor is used to monitor the number of turns of the rotation of the rotary encoder disc and is used to control the buffer start and stop of the photovoltaic module 2.

[0082] The present invention also sets a control box 7. Inside the control box 7 are components such as a power supply and a single-chip microcomputer. The single-chip microcomputer is signal-connected to the sensing component, the first motor 301, and the second motor 410, and is used to receive data and send instructions.

[0083] The rotary encoder disc and the photoelectric inductor of the rotary encoder disc 412 and the photoelectric inductor 401 are as Figure 6 shown. The rotary encoder disc is fixed to the rotating shaft 411, and the photoelectric inductor 401 is fixed to the mounting strip 407. The mounting strip 407 is fixed to the acting plate 314 through the mounting piece 406. When the second motor 410 works to drive the rotary encoder disc 412 to rotate, the photoelectric inductor 401 monitors the number of turns of the rotation of the rotary encoder disc 412. The number of turns for buffering is set in advance. For example, to adjust the photovoltaic module to 30°, the photoelectric inductor monitors the number of turns of the rotation of the rotary encoder disc in real time and converts the number of turns of the rotary encoder disc into the angle of the photovoltaic panel. This is the prior art and will not be elaborated here. For example, at the beginning of rotation, the single-chip microcomputer controls the second motor 410 to start slowly. When the photovoltaic panel rotates to 5°, it accelerates to a uniform speed state. When the photovoltaic panel rotates to 25°, the single-chip microcomputer controls the second motor 410 to slow down until it stops, realizing slow start and slow stop to prevent the photovoltaic panel from jamming or being damaged.

[0084] It also includes a telescopic photoelectric inductor, and the telescopic photoelectric inductor is used to monitor the extended length of the photovoltaic module 2.

[0085] The telescopic photoelectric inductor includes an induction piece 409 and a photoelectric inductor 408, and is used to monitor the moving length of the rack 405 to illustrate the extended length of the photovoltaic module 2, so as to control sunshading.

[0086] The present invention also sets a WiFi control module, which cooperates with terminals such as mobile phones, tablets, and remote controls to facilitate remote control.

[0087] A method for using an intelligent photovoltaic sunshade

[0088] Control the first motor 301 to operate, so that the first motor 301 drives the long shaft 302 and at least one transmission rod 303 to rotate, thereby driving the synchronous belt 306 to rotate and driving the moving strip 310 to move forward. The moving strip 310 drives the acting plate 314 to move forward, and the acting plate 314 drives the photovoltaic module 2 to extend outwards until it extends to the required length. At this time, the photovoltaic module 2 extends partially or completely;

[0089] When the photovoltaic module 2 extends completely, control the second motor 410 to operate, so that the second motor 410 drives the rotating shaft 411 to rotate, thereby driving the gear 413 to rotate. The gear 413 drives the rack 405 to move backward. Under the hinge action of the connecting rod 414 and the hinge 415, the photovoltaic module 2 is urged to rotate downward with the hinge 415 as the axis, thereby adjusting the sunshading and power generation angles of the photovoltaic module 2;

[0090] Real-time monitor the angle parameters of the photovoltaic module. When the angle parameters meet the first condition, control the second motor 410 to operate to adjust the angle of the photovoltaic module 2. When the angle parameters meet the second condition, control the second motor 410 and the first motor 301 to operate to retract the photovoltaic module 2;

[0091] When the second motor 410 is operating, real-time monitor the number of rotation turns of the rotary code disc. When the number of turns meets the third condition, slow down the speed of the second motor 410.

[0092] Among them, the first condition when the angle parameters meet the first condition can be that the angle of the up-and-down swing of the photovoltaic module is greater than 5° and less than 3 times, which can be set to change the working angle of the photovoltaic module. The second condition can be that the angle of the up-and-down swing is greater than 5° and more than 3 times, which can be set to directly retract the photovoltaic module.

[0093] The photovoltaic panel of the present invention can intelligently adjust the inclination according to the sun angle to ensure the best power generation efficiency. According to the local lighting time in different quarters, the system automatically sets different angles in several time periods within a day to achieve the best power generation efficiency. The conversion between different angles is automatically adjusted by the system without human intervention, realizing the intelligent use of family residences. Of course, the present invention can still be manually controlled by configuring terminals such as APPs.

[0094] The present invention is installed and fixed by using the balcony ceiling, which does not occupy the practical area of the family. At the same time, the photovoltaic panel can automatically adjust the angle according to the light to achieve the highest efficiency of power generation, and can also retract and extend the photovoltaic panel according to the day and night weather conditions, effectively avoiding the damage and service life problems of the photovoltaic panel caused by external reasons.

[0097] All components are pre-installed and tested in the factory to ensure the stability and reliability of the system.

[0098] 2. Ceiling installation:

[0099] Install hooks and expansion screws in the selected area at the top of the balcony, and hoist the equipment firmly.

[0100] 3. Wiring and power generation:

[0101] Professional personnel will connect the photovoltaic power generation line to the household power supply and extend the photovoltaic panel to generate electricity during daylight hours.

[0102] The present invention has the following advantages:

[0103] 1. Innovative installation method:

[0104] Adopt ceiling-mounted installation to avoid occupying balcony space and improve the aesthetics of the residence.

[0105] The present invention extends outside the building through electric automatic control, which can be understood as cantilevering outside the outer surface of the building at the upper end of the balcony; the applicable scenario is for buildings of 6 floors and below;

[0106] The entire set of photovoltaic power generation equipment is pre-installed offline and then installed on the ceiling. The present invention gives an implementable overall size: width * depth * height = 1670mm * 1530mm * 160mm, while the general size of a household balcony is: width * depth * height = 3000mm * 1650mm * 3000mm. After installing the entire set of photovoltaic devices on the ceiling according to the space size, the net height of the balcony is still 2840mm, without affecting the normal usable area of the household balcony.

[0107] 2. Intelligent angle adjustment:

[0108] Combined with motor drive and intelligent algorithm to ensure that the photovoltaic panel is always at the best illumination angle, improving the power generation efficiency.

[0109] The angle of the photovoltaic panel for power generation is automatically adjusted according to the illumination angle in several time periods of a day. The two sides of the photovoltaic panel are automatically inclined by the motor, that is, the connecting rod 414 for angle adjustment. The motor inclined support force is greater than 250KG, so that the entire device works stably and efficiently, avoiding the shaking of the entire device and affecting power generation;

[0110] 3. Automatic telescopic system:

[0111] Built-in wind speed detection and rain sensor to automatically retract the photovoltaic panel to prevent damage in bad weather.

[0112] The present invention adopts a single-chip microcomputer + WiFi + motor + synchronous belt + sensor + wind-sensing gyroscope to intelligently detect the weather conditions during the day and night. For example, when it rains or has strong winds, the wind-sensing gyroscope senses the shaking amplitude of the photovoltaic panel and then determines whether to adjust the angle or retract the photovoltaic panel, thereby effectively improving the power generation efficiency and extending the service life.

[0113] 4. Integrated shading and lighting:

[0114] Extended photovoltaic panels provide shade, and built-in LED light strips can be used for nighttime illumination.

[0115] The extended photovoltaic panels can be infinitely adjusted in angle by remote control to serve as sunshade. At the same time, a light strip is installed at the bottom to provide lighting at night.

[0116] 5. High reliability design:

[0117] Using high-strength materials and double-support structure, the maximum load-bearing capacity of the motor is 250kg, ensuring long-term and stable operation of the equipment.

[0118] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
