[0002] A sunroom is a light-transmitting, non-traditional building constructed with a metal frame and glass embedded in the metal frame. Sunrooms usually have good lighting. In addition, with the development of new energy sources, photovoltaic power generation technology is becoming more and more mature. Therefore, the method of installing photovoltaic panels on the roof of the sunroom to generate electricity has emerged. This can not only meet people's needs for sunlight, but also effectively utilize solar energy resources, save energy and protect the environment.

[0003] In the prior art, photovoltaic panels are generally installed directly on the outside of the building. After being exposed to rain, wind and sun, and after long-term use, the photovoltaic panels may have problems such as dust accumulation, corrosion, and cracking, thereby reducing the service life of the photovoltaic panels. At the same time, photovoltaic panels are generally fixedly installed, so that their inclination angle cannot be adjusted according to the light angle, resulting in insufficient light and low sunlight utilization.

A seal is formed on one side of the top plate and a counterweight is formed on the other side for adjusting the posture of the top plate. The driving part is arranged on the crossbeam and is used for driving the push rod to move.

[0006] Furthermore, the counterweight is in the shape of a round rod and is installed on the other side of the top plate in the length direction of the top plate.

[0007] Furthermore, a positioning block is provided on the inclined beam for limiting the movement of the counterweight part and for allowing the top plate to rotate around the axis of the counterweight part.

[0008] The beneficial effects of the present invention are: 1.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1 The present application embodiment provides a movable photovoltaic roof integrated structure, such as Figure 1 to Figure 8 As shown, it includes a top frame 1, a push rod 2, a mounting plate 3, a hinge assembly 4, a sliding guide assembly 5, a top plate 6 and a driving part 7.

[0021] like Figure 1 and Figure 2 As shown, the top frame 1 is square, with a cross beam 11 in the middle, the cross beam 11 is parallel to the side of the top frame 1, six longitudinal beams 12 are vertically arranged on the cross beam 11, and each longitudinal beam 12 is arranged in an array along the length direction of the cross beam 11 and in two rows, with three longitudinal beams 12 in each row, two of which are located at both ends of the cross beam 11, and one longitudinal beam 12 is located in the middle of the cross beam 11. The two rows of longitudinal beams 13 are arranged at a predetermined distance along the width direction of the top frame 1 to leave space for the installation of components such as the push rod 2 and the mounting plate 3. At the same time, the cross beam 11, the inclined beam 13 and the top frame 1 constitute a roof metal frame with a triangular main body. Glass panels are embedded in the frame, which has high strength and structural stability, and can effectively ensure the stability of the operation of other components.

[0022] like Figure 1 , Figure 3As shown, the push rod 2 is arranged in the middle of the two rows of longitudinal beams 12 in the length direction of the cross beam 11, and is movable along the length direction of the longitudinal beam 12; there are two pairs of mounting plates 3, both of which are arranged in the length direction of the push rod 2 and are located between the two ends of the top frame 1, one side of the two mounting plates 3 is hinged to the push rod 2, and accordingly, the hinge axis is the axis of the push rod 2, and a mounting assembly 31 is provided on the mounting plate 3, which is used to attach the photovoltaic panel to the mounting plate 3 in parallel.

[0023] like Figure 1~Figure 4 As shown, the hinge assembly 4 is arranged at the top of the longitudinal beam 13, and is used to hinge the bottom of the corresponding mounting plate 3, and its hinge axis is arranged parallel to the push rod 2. Specifically, the hinge assembly 4 includes a mounting seat 41 arranged at the top of the longitudinal beam 12 and a rotating block 42 hinged on the mounting seat 41, and the hinge axis of the rotating block 42 is arranged parallel to the push rod 2. Figure 3 and Figure 4 As shown, the sliding guide assembly 5 is arranged between the mounting plate 3 and the hinge assembly 4, and is used to enable the mounting plate 3 to move along its own width direction. Specifically, the sliding guide assembly 5 includes support plates 51 vertically arranged on both sides of the bottom of the mounting plate 3, and three guide rods 52 are arranged between the two support plates 51. The guide rods 52 are arranged in the width direction of the mounting plate 3 and arranged in an array along the length direction of the mounting plate 3. Each guide rod 52 is slidably arranged along its own axis and penetrates the corresponding rotating block 42. The hinge axis of the rotating block 42 is spatially orthogonal to the axis of the guide rod 52.

[0024] like Figure 2~Figure 5 As shown, there are two top plates 6, both of which are arranged in the length direction of the push rod 2. The middle parts of the two top plates 6 are respectively hinged to the other side of the corresponding mounting plate 3, and the hinge axis is arranged parallel to the push rod 2. A seal 61 is formed on one side of the top plate 6, and a counterweight part 62 is formed on the other side for adjusting the posture of the top plate 6; the driving part 7 is arranged on the cross beam 11, and is used to drive the push rod 2 to move.

[0025] According to the posture of the mounting plate 3, the photovoltaic panel can be divided into a storage state and an unfolded state, as follows: Photovoltaic panel storage process: like Figure 1~Figure 5As shown, the driving unit 7 drives the push rod 2 to move downward, and the push rod 2 pulls the mounting plate 3, so that the mounting plate 3 rotates around the axis of the push rod 2 and the hinge axis of the rotating block 42, and at the same time the guide rod 52 slides along its own axis, so that the two mounting plates 3 are retracted between the two rows of longitudinal beams 12. Since the counterweight part 62 is subjected to the vertical downward gravity and cooperates with the hinge between the top plate 6 and the mounting plate 3, when the mounting plate 3 is stored, the counterweight part 62 formed on the other side of the top plate 6 will overlap on the inclined beam 13, and the seal 61 formed on one side of the top plate 6 is located above the two rows of longitudinal beams 12. As the push rod 2 moves downward to continuously retract the mounting plate 3, the counterweight part 62 will move along the inclined beam 13, and the two top plates 6 will gradually become parallel to the corresponding inclined beams 13, and the seals 61 on the two top plates 6 will gradually move closer; when the push rod 2 moves down to a preset distance, the seals 61 of the two mounting plates 3 are closed, and the mounting plate 3 and the photovoltaic panels installed thereon are stored in the space formed by the top plate 6 and the two rows of longitudinal beams 12. At this time, the photovoltaic panels are stored. By hingedly setting the mounting plate 3 and the push rod 2, and cooperating with the hinge assembly 4 and the sliding guide assembly 5, the photovoltaic panel is stored. At the same time, by hingedly setting the mounting plate 3 and the top plate 6, and under the action of the seal 61 and the counterweight 62, the two seals 61 are automatically closed during the storage process of the mounting plate 3, and the top plate 6 blocks the top of the two rows of longitudinal beams 12, so as to protect the photovoltaic panel on the mounting plate 3 from wind and rain, avoid corrosion and aging, and thus effectively improve the service life of the photovoltaic panel.

[0026] When the push rod 2 moves down to a preset distance, the push rod 2 is fixed, so that the position of the mounting plate 3 is fixed, the two seals 61 are closed, and the counterweight 62 is placed on the inclined beam 13. When the top plate 6 is subjected to external force, such as strong wind or heavy rain, the top plate 6 has a tendency to rotate around the hinge axis between it and the mounting plate 3, such as Figure 5 As shown, when the external force applied to the top plate 6 is directed toward the hinge axis between the seal 61 and the top plate 6, since the position of the mounting plate 3 is fixed, that is, the hinge axes of the two top plates 6 and the corresponding mounting plates 3 are fixed, the top plate 6 can withstand the external force directed toward the hinge axis between the seal 61 and the top plate 6 without rotation or deformation; when the external force applied to the top plate 6 is directed toward the hinge axis between the counterweight portion 62 and the top plate 6, since the counterweight portion 62 rests on the inclined beam 13, the inclined beam 13 limits the rotation of the top plate 6, so that the top plate 6 can withstand the external force directed toward the hinge axis between the counterweight portion 62 and the top plate 6 without rotation or deformation. In summary, when the photovoltaic panel is in the folded state, the shielding structure formed by the top plate 6 for the photovoltaic panel has good stability and can effectively resist external forces without deformation.

[0027] Correspondingly, such as Figure 2 As shown, the length of the top plate 6 should be greater than the length of the top frame 1. At the same time, after the two seals 61 are closed, the distance between the counterweights 62 of the two top plates 6 should be greater than the predetermined distance between the two rows of longitudinal beams 12, so that the top plate 6 can completely block the two rows of longitudinal beams 12.

[0028] Photovoltaic panel deployment process: like Figure 5~Figure 7 As shown, when the sun is directly above the roof, the driving unit 7 drives the push rod 2 to move upward, causing the mounting plate 3 to rotate around the axis of the push rod 2 and the hinge axis of the rotating block 42. At the same time, the push rod 2 pushes out the two guide rods 52, causing the two guide rods 52 to move along their own axes out from between the two rows of longitudinal beams 12. The push rod 2 continues to move upward until the two mounting plates 3 rotate to be perpendicular to the longitudinal beams 12. At this time, the two guide rods 52 are coaxial, the mounting plates 3 are coplanar, and the photovoltaic panel is unfolded to face directly above the roof. At the same time, the gravity exerted on the counterweight 62 causes one side of the top plate 6 to face upward.

[0029] like Figure 7~Figure 9 As shown, when the sun is on both sides of the roof, the driving unit 7 continues to drive the push rod 2 to move upward, so that the mounting plate 3 rotates around the axis of the push rod 2 and the hinge axis of the rotating block 42. At the same time, the push rod 2 pulls the two guide rods 52 along its own axis to move directly above the two rows of longitudinal beams 12. The counterweight 62 is placed on the inclined beam 13 and causes the top plate 6 to rotate to one side and gradually approach the mounting plate 3. The mounting plate 3 gradually turns from a previous posture perpendicular to the longitudinal beam 12 to a posture parallel to the inclined beam 13, that is, the photovoltaic panel is adjusted from an angle facing directly above the roof to an angle facing both sides of the roof. As the push rod 2 continues to move upward, the inclination angle formed by the photovoltaic panels 3 on the two mounting plates and the plane where the top of the top frame 1 is located becomes larger and larger. In actual application, the height of the push rod 2 can be adjusted according to the specific position on both sides of the roof to change the inclination angle of the photovoltaic panel to maximize the amount of light received and effectively improve the utilization rate of sunlight.

[0030] like Figure 8 and Fig. 9 As shown, the push rod 2 continues to move up to the maximum height, and the photovoltaic panel is fully unfolded. At this time, the other side of the mounting plate 3 abuts against the inclined beam 13 to form a mechanical limit, so that the structure of the mounting plate 3 is stable. When the mounting plate 3 is subjected to external force, such as lateral wind, it can resist deformation and keep the position of the photovoltaic panel unchanged.

[0031] Correspondingly, such as Figure 6~Figure 8 As shown, the photovoltaic panel should be installed close to the push rod 2 to prevent the top plate 6 from blocking sunlight when the photovoltaic panel is in the unfolded state.

[0032] Preferably, Figure 2 As shown, side plates 63 may be provided at both ends of the top plate 6 , and when the two seals 61 are closed, the side plates 63 are also closed, so that both ends of the two rows of longitudinal beams 12 can be shielded.

[0033] Preferably, Figure 5As shown, a positioning plate 32 may be provided on the other side of the mounting plate 3, which faces between the hinge axis of the top plate 6 and the counterweight portion 62, and is used to limit the minimum distance between one side of the counterweight portion 62 of the top plate 6 and the mounting plate 3. When the photovoltaic panel is stored, the top plate 6 will be against the edge of the positioning plate 32 in conjunction with the counterweight portion 62, and the posture of the top plate 6 will be adjusted to facilitate the closing of the two seals 6, thereby improving the reliability of the storage of the photovoltaic panel.

[0034] Example 2 As a further implementation of the above embodiment 1, Figure 6 and Figure 7 As shown, the push rod 2 moves upward to make the two guide rods 52 coaxial, the two mounting plates 3 are perpendicular to the longitudinal beam 12, and the counterweight 62 makes one side of the top plate 6 seal 61 face upward. At this time, if the top plate 6 is subjected to a lateral force, such as a lateral wind blowing toward the top plate 6, since the top plate 6 is not fixed, the two guide rods 52 are in a coaxial state and slide with the rotating block 42. The lateral force may cause the top plate 6 to rotate around the hinge axis between it and the mounting plate 3. The lateral force may also be transmitted to the two guide rods 52, thereby causing the mounting plate 3, the guide rods 52 and other components to shake. Under long-term use, it may cause wear and abnormal noise at the connection and cooperation of each component. In severe cases, it may cause the photovoltaic panel to be unable to be stored and unfolded normally. This embodiment proposes a preferred solution, which is as follows: like Figure 5~Figure 7 As shown, the counterweight portion 62 is in the shape of a round rod and is installed on the other side of the top plate 11 in the length direction of the top plate 11. A positioning block 18 is provided on the inclined beam 13. The positioning block 18 is L-shaped. The bottom surface of the horizontal part of the positioning block 18 can be welded to the inclined surface 13 of the inclined beam, and the vertical part of the positioning block 18 is arranged perpendicular to the inclined beam 13. One end of the horizontal part of the positioning block 18 is set as an arc surface for receiving the counterweight portion 62.

[0035] like Figure 5 and Figure 7 As shown, the push rod 2 moves upward to adjust the mounting plate 3 in the storage state to be perpendicular to the longitudinal beam 12. During this period, the counterweight portion 62 moves and rotates with the mounting plate 3 and rests on the arc surface of the positioning block 18. When the mounting plate 3 is parallel to the longitudinal beam 12, the counterweight portion 62 is inserted into the right angle formed by the horizontal and vertical portions of the positioning block 18, and the counterweight portion 62 is tangent to the contact surface of the horizontal and vertical portions of the positioning block 18.

[0036] like Figure 7As shown, the two guide rods 52 are coaxial and perpendicular to the longitudinal beam 12, and the counterweight portion 62 is stuck in the right angle formed by the horizontal portion and the vertical portion of the positioning block 18. When the top plate 6 is subjected to a lateral force, since the counterweight portion 62 is stuck in the right angle formed by the horizontal portion and the vertical portion of the positioning block 18, and the mounting plate 3 is always in a state perpendicular to the longitudinal beam 13, the top plate 6 will not rotate due to the lateral force; at the same time, the overall structure at this time uses the two guide rods 52 as the upper bottom, the line between the axes of the counterweight portion 62 as the lower bottom, and the top plate 6 part between the other side of the mounting plate 3 and the counterweight portion 62 as the waist, forming an isosceles trapezoidal structure. After the force is transmitted to the two guide rods 52, the guide rods 52 tend to move along their own axes. If the guide rod 52 serving as the upper base tries to translate left and right along its own axis, the two top plates 6 serving as waists need to rotate around the axis of the counterweight portion 62. The waist length of the isosceles trapezoid is fixed, that is, the width of the top plate 6 is fixed, and the motion trajectory of the upper base must be an arc. The arc trajectory will inevitably cause the height of the guide rod 52 serving as the upper base to change. Since the two guide rods 52 are respectively slidably fitted in the corresponding rotating blocks 42 and are coaxially arranged, the mounting plate 3 is hinged to the push rod 2, and the two guide rods 52 cannot have arc motion.

[0037] To sum up, when the mounting plate 3 is rotated to be perpendicular to the longitudinal beam 12, that is, when the photovoltaic panel is unfolded to face directly above the roof, the overall structure formed by the various components has good stability at this time, and can effectively resist the translation of the guide rod 52 along the axis caused by the lateral force and effectively reduce the shaking of other components, thereby ensuring the service life of each moving part, and stabilizing the posture of the photovoltaic panel, ensuring that the photovoltaic panel can be stored and unfolded normally, and improving reliability.

[0038] like Figure 5 , Figure 8 , Fig. 9As shown, the push rod 2 drives the mounting plate 3 perpendicular to the longitudinal beam 12 to rotate until it is parallel to the inclined beam 13. While the mounting plate 3 rotates around the hinge axis of the rotating block 42, it moves along its own axis to the top of the two rows of longitudinal beams 12, thereby driving the top plate 6 to rotate around the axis of the counterweight portion 62 to the side of its seal 61 close to the mounting plate 3. At this time, the lateral force has little effect on the overall structure because the mounting plate 3, the guide rod 52 and the top plate 6 are all close to the parallel inclined beam 13. After the lateral force is decomposed, it is a force perpendicular to the top plate 6 and an upward force along the width direction of the top plate 6. The mounting plate 3 is subjected to the same force. After the push rod 2 is fixed, the two mounting plates 3 and the connecting line of the hinge axis of the two mounting plates 3 and the top plate 6 form a structurally stable triangle, which can enable the mounting plate 3 to effectively resist the lateral force without deformation. The counterweight portion 62 is stuck in the right angle of the positioning block 18. When the mounting plate 3 is fixed, the top plate 6 will not rotate around the hinge axis with the mounting plate 3 when subjected to the lateral force, and it also has good stability. When the push rod 2 continues to move upward to the maximum height, the photovoltaic panel is fully unfolded. At this time, the other side of the mounting plate 3 abuts against the inclined beam 13 to form a mechanical limit, and continues to maintain good stability.

[0039] Preferably, Fig. 9 As shown, in order to prevent the other side of the mounting plate 3 from directly contacting the inclined beam 13 and causing wear, a receiving block 16 may be provided on the inclined beam 13, one side of which is provided with a matching groove 17 adapted to the guide rod 52 along the length direction of the inclined beam 13; when the guide rod 52 is engaged in the matching groove 17, the guide rod 52 is parallel to the inclined beam 13, which can not only effectively prevent the mounting plate 3 from directly contacting the inclined beam 13, but also effectively locate the position of the mounting plate 3.

[0040] Example 3 As a further implementation of the above-mentioned embodiment 2, since the lengths of the push rod 2, the mounting plate 3 and the top plate 6 are all relatively long, and the stroke of the push rod 2 moving up and down is relatively long, the selection of the driving part 7 is very important.

[0041] The storage and deployment of photovoltaic panels require that the driving stroke of the driving unit 7 be long enough, and that the driving unit 7 has the function of supporting the push rod 2 at multiple points along its length direction to avoid uneven force between the driving unit 7 and the push rod 2. When the push rod 2 is driven to move to a higher height, the push rod 2 and the driving unit 7 will shake, wear, make abnormal noises, etc., and long-term use may damage the driving unit 7. The photovoltaic panel also needs to be fixed in a specific posture according to the sunlight, which means that the driving unit 7 also needs to have a self-locking function, that is, when the driving unit 7 stops working, the push rod 2 can maintain the current position, thereby fixing the posture of the photovoltaic panel. The driving unit 7 needs to meet the above conditions to enable the photovoltaic panel to be normally deployed and stored.

[0042] like Figure 1As shown, there is a pair of cross beams 11, and two rows of longitudinal beams 12 are respectively located on the corresponding cross beams 11. Three groups of mounting frames 71 are arranged on the cross beam 11, and the three groups of mounting frames 71 are evenly arranged along the length direction of the cross beam 11. The mounting frame 71 in the middle position is located in the middle of the cross beam 11, and a bearing frame 74 is also provided below the middle of the cross beam 11. The driving part 7 includes a commutator 75 and two electric screw lifting mechanisms 72. The commutator 75 is arranged on the mounting frame 71 in the middle position and is fastened by screws. The two electric screw lifting mechanisms 72 are respectively installed on the mounting frames 71 on both sides of the commutator 75. The screws face the length direction of the longitudinal beam 12 and are connected to the push rod 2. A transmission rod 76 arranged parallel to the push rod 2 is provided between the electric screw lifting mechanism 72 and the commutator 75, one end of which is connected to the output end of the commutator 75, and the other end is connected to the input end of the electric screw lifting mechanism 72. A motor 73 is provided on the bearing frame 74, and its driving end is connected to the input end of the commutator 75.

[0043] The motor 73 rotates, and the commutator 75 converts the power of the motor 73 into the rotation of the transmission rod 76 around its own axis, so that the active end of the electric screw lifting mechanism 72, that is, the screw 77, moves up and down. The two electric screw lifting mechanisms 72 are linked by the transmission rod 76 and the commutator 75, so that the push rod 2 can be supported at multiple points, and the synchronization of the lifting of the two screw rods 77 can be effectively guaranteed, thereby improving the stability of the photovoltaic panel when it is stored and unfolded; at the same time, the screw rod 77 has a longer stroke, which can meet the requirements of pushing rod lifting.

[0044] When selecting the screw 77 in the electric screw lifting mechanism 72, a trapezoidal screw needs to be used because the drive unit 7 needs to have a self-locking function, that is, the lead angle of the screw 77 needs to be smaller than the friction angle. The trapezoidal screw has a self-locking function because of its smaller lead angle and greater friction.

[0045] Specifically, Figure 1 As shown, in order to enhance the self-locking property of the screw rod 77, two sliding rods 14 arranged in an array along the length direction of the push rod 2 can be provided between the two cross beams 11. The two sliding rods 14 are respectively located at both ends of the push rod 2. The sliding rods 14 face the length direction of the longitudinal beam 12 and are connected to the push rod 2. Two guide seats 15 are provided on the cross beam 11. The two sliding rods 14 slide through the guide seats 15 along their own axes. In this way, through the cooperation of the sliding rod 14 and the guide seat 15, not only can the lifting and lowering of the push rod 2 be guided, and the lifting and lowering stability of the push rod 2 can be improved, but also the lateral force can be separated, the radial load of the screw rod 77 can be reduced, the self-locking property can be improved, and the stability and reliability of the storage and deployment of the photovoltaic panel can be further improved.

[0046] Preferably, in order to further ensure the self-locking property of the screw rod 77, an electromagnetic brake may be provided at the screw rod 77 to automatically lock the screw rod 77 when the power is cut off.

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
