[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0028] like Figure 1-Figure 4As shown, a specific embodiment of the present invention provides an aluminum alloy photovoltaic sunroom, comprising an aluminum alloy vertical beam 1, an aluminum alloy horizontal beam 2, a light-transmitting plate 3, a double-sided photovoltaic unit 4 and a light-guiding unit 5; the aluminum alloy horizontal beam 2 is arranged at a preset height of the aluminum alloy vertical beam 1, and the light-transmitting plate 3 is arranged on the outer surfaces of the aluminum alloy horizontal beam 2 and the aluminum alloy vertical beam 1; the double-sided photovoltaic unit 4 is arranged on the top of the aluminum alloy photovoltaic sunroom, comprising a double-sided photovoltaic panel 41 and a containing box 42, and the double-sided photovoltaic panel 41 is arranged on the top of the containing box 42; the light-guiding unit 5 comprises a reflecting mechanism 51 and an optical fiber 52, and the reflecting mechanism 51 is arranged on the wall side of the aluminum alloy photovoltaic sunroom, and is used to guide the light on the wall side of the aluminum alloy photovoltaic sunroom into the optical fiber 52; one end of the optical fiber 52 is arranged at the reflecting mechanism 51, and the other end extends into the containing box 42.

[0029] By adopting the above scheme, the advantages of the existing double-sided photovoltaic panels 41 can be fully utilized, and the light from the side of the building can be guided to the back of the double-sided photovoltaic panels 41 located on the top of the building through the optical fiber 52, thereby increasing the power generation. By focusing the light of a larger area through the reflective mechanism 51, the light intensity in the optical fiber 52 can be increased, thereby improving the photoelectric conversion efficiency.

[0030] In order to simplify the structure of the sun room, the aluminum alloy vertical beam 1 is provided with a wire harness accommodating cavity 11 and a wire entry hole 12 on the side; the optical fiber 52 can enter the wire harness accommodating cavity 11 from the wire entry hole 12 and reach the top of the aluminum alloy photovoltaic sun room, thereby preventing the optical fiber 52 from being arranged outside the aluminum alloy vertical beam 1 and affecting the overall appearance of the sun room, and also protecting the relatively fragile optical fiber 52 and preventing the optical fiber 52 from being damaged by the outside.

[0031] Preferably, both the front and back sides of the double-sided photovoltaic panel 41 have photoelectric conversion capabilities, the housing box 42 and the double-sided photovoltaic panel 41 together form a closed space, and the inner surface of the housing box 42 is provided with a reflective layer 43. The light in the optical fiber 52 is emitted from its end to the back of the double-sided photovoltaic panel 41, and part of the light that diverges outward is reflected by the reflective layer 43 back to the back of the double-sided photovoltaic panel 41 for photoelectric conversion, thereby improving the overall photoelectric conversion rate.

[0032] Combination Figure 5As shown, in order to allow the light from the side of the building to be introduced into the optical fiber 52 according to demand, or to be illuminated into the room to provide daylighting, this embodiment provides a newly designed reflective mechanism 51. The reflective mechanism 51 includes a reflective film 53, an elastic film 54, a shell 55 and a bending control mechanism 56. The edge of the reflective film 53 is fixed to the shell 55 through the elastic film 54; a limit sleeve 531 is provided on the bottom surface of the reflective film 53, and the bending control mechanism 56 includes an elastic strip 561 and a push-pull mechanism. The elastic strip 561 passes through the limit sleeve 531, one end of which is fixed in the shell 55, and the other end can be driven by the push-pull mechanism to translate, thereby changing its own bending degree. The reflective film 53 is coated with a reflective coating on its surface, and its own elasticity is relatively low. The elastic film 54 can be made of rubber to provide sufficient elastic deformation when the reflective film 53 is deformed.

[0033] The elastic strip 561 has a preset curvature in the initial state. Figure 6 and Figure 7 As shown, the push-pull mechanism includes: a threaded column 562 fixedly connected to one end of the elastic strip 561, and a limit groove 563 arranged axially on the surface of the threaded column 562; a driving nut 564, which is sleeved on the surface of the threaded column 562 and has a first locking groove 565 on the side; a driving wheel 566, which is connected to the telescopic motor 567 and meshed with the driving nut 564; a limit plate 568, the bottom surface of which can move along the limit groove 563 and the end of which can extend into the first locking groove 565.

[0034] Preferably, the push-pull mechanism also includes a reversing solenoid valve 569 and a reversing ring 560, the reversing ring 560 is sleeved on the outside of the threaded column 562 and connected to the limit plate 568; a positioning ring 551 fixedly connected to the shell 55 is provided on the outside of the reversing ring 560, the reversing solenoid valve 569 is provided on the positioning ring 551, and a second locking groove 552 is provided on the side of the positioning ring 551 facing the limit plate 568, the reversing solenoid valve 569 is also connected to the reversing ring 560, and can drive the limit plate 568 to move between the first locking groove 565 and the second locking groove 552 through the reversing ring 560.

[0035] The working principle of the above-mentioned reflective mechanism 51 is as follows: when there is sufficient sunlight outside and it is necessary to use the light from the side of the building to generate electricity, the elastic strip 561 is in the initial position, at which time the elastic strip 561 is slightly bent downward, and then the reversing solenoid valve 569 drives the limit plate 568 to retract, and the limit plate 568 is clamped into the second locking groove 552. At this time, the rotation of the threaded column 562 is locked by the limit plate 568 and can only move horizontally. The telescopic motor 567 drives the driving nut 564 to rotate through the driving wheel 566, and the driving nut 564 drives the threaded column 562 to extend toward the reflective film 53 through its own internal thread. Since the position of the other end of the elastic strip 561 is limited, the elastic strip 561 can only bend gradually, driving the reflective film 53 to be concave downward, so that the reflective film 53 forms a concave lens, which reflects and converges the light at the light-inlet end of the optical fiber 52, and guides the light into the back of the double-sided photovoltaic panel 41 through the light-guiding effect of the optical fiber 52.

[0036] When there is insufficient sunlight outside and more lighting is needed in the sun room, the various components of the push-pull mechanism are operated in reverse, so that the elastic strip 561 returns to the initial position. Then, the reversing solenoid valve 569 drives the limit plate 568 to extend, and the front end of the limit plate 568 is stuck in the first locking groove 565. At this time, the threaded column 562 and the drive nut 564 are locked together, and the telescopic motor 567 drives the drive nut 564 to rotate through the active wheel 566, and the threaded column 562 rotates 180 degrees, so that the elastic strip 561 is rotated to a state of slightly bending upward. Then, the steps of driving the reflective film 53 to bend downward are imitated, so that the reflective film 53 bulges upward to form a convex lens structure. The light from the outside on the side of the sun room is scattered by the reflective film 53 with a convex lens structure, and enters the room more gently to provide lighting function, meeting the indoor lighting needs on cloudy days.

[0037] With the above structure, the reflective mechanism 51 can focus or diverge light according to demand, has a compact structure, is low in cost, has little deformation of the reflective film 53, and has a long service life.

[0038] In order to ensure that the light-emitting film forms a reflective surface close to an arc shape, two sets of the push-pull mechanisms may be arranged perpendicularly to each other at the bottom of the reflective film 53 .

[0039] In addition, in order to ensure that when the incident angle of sunlight is different, the reflective mechanism 51 can still align the reflected light to the incident end of the optical fiber 52. The reflective mechanism 51 is connected to the swing mechanism 57, and the swing mechanism 57 includes a seat bearing 571, a swing shaft 572 and a servo motor 573. The swing shaft 572 is arranged on both sides of the reflective mechanism 51, and the swing shaft 572 extends into the seat bearing 571 and is connected to the servo motor 573. When the servo motor 573 rotates, it can drive the reflective mechanism 51 to swing to a predetermined angle through the swing shaft 572.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
