Description

Technical Field

[0001] The invention relates to the technical field of sunshades, and in particular to a photovoltaic electric device with built-in insulating glass. Background Art

[0002] At present, insulating glass is widely used in the field of energy-saving buildings due to its good heat insulation and sound insulation effects. However, in hot weather, it is easy to cause the indoor temperature to rise and it is difficult to dissipate heat. Therefore, the existing technology uses the method of installing sunshades to improve this problem.

[0003] Patent document CN102352723A, published on February 15, 2012, discloses a hollow glass with a built-in sunshade. The invention comprises two glass surfaces, a sunshade positioned between the two glass surfaces, a traction mechanism for controlling the sunshade, and a traction device fixed to the traction mechanism. An operating device is provided on the exterior of the hollow glass, opposite the traction device. At least one of the operating device and the traction device comprises a magnetic material, and the two are connected by magnetic force. At least one of the operating device and the traction device comprises a first support structure, a first rotating shaft fixed to the first support structure, and a roller with a resistance position mounted on the first rotating shaft. During one rotation cycle, the roller has at least two contact points with the hollow glass closest to the first rotating shaft. Due to the use of the roller with the resistance position, when the sunshade stops moving, it is not only affected by the friction of the contact surface but also by the horizontal component of the magnetic force, thus providing an automatic limit function, reducing operational difficulty, and improving the operating feel.

[0004] The retractable sunshade is integrated into the insulating glass, so that the structure of the retractable rope is also isolated in the insulating glass. The existing retractable structure will cause the ropes to overlap and wind, which may easily cause unstable retraction and extension. If the ropes on one side stick together, the curtain will be tilted and then stuck, and it will seriously affect the use in the closed insulating glass. Therefore, there is an urgent need for a photovoltaic electric device with built-in insulating glass to solve the above problems. Summary of the Invention

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] See also Figure 1-12, a photovoltaic electric device with built-in insulating glass provided by an embodiment of the present invention includes a frame body 2 fixedly arranged inside the insulating glass 1, and a louver curtain 3 is arranged on its lower side; a wire winding wheel 4 is movably arranged inside the frame body 2, and its outer wall is connected to the louver curtain 3 through a suspension rope 5; a driving component is used to drive the wire winding wheel 4 to rotate spirally; a photovoltaic panel 6 is arranged on one side inside the frame body 2, and a light-transmitting area corresponding to the light-absorbing surface of the photovoltaic panel 6 is arranged on one side of the insulating glass 1 facing the outside; a power control unit 7 is arranged outside the insulating glass 1 and is electrically connected to the photovoltaic panel 6 for storing the electricity generated by the photovoltaic panel 6 to supply energy to the driving component.

[0038] Specifically, the frame body 2 is composed of multiple components spliced together, and an area for arranging a wire winding structure and a photovoltaic area for arranging the photovoltaic panel 6 are formed inside; the insulating glass 1 includes double-layer glass sandwiching the opposite sides of the frame body 2, and the two opposite horizontal sides of the insulating glass 1 are set as partitions; one side of the insulating glass 1 faces the indoor, and the other side faces the outdoor, and the photovoltaic area is arranged closer to the side of the insulating glass 1 facing the outdoor; "C"-shaped side plates are arranged at the two lower edges of the frame body 2, and the two opposite sides of the louver curtain 3 are embedded in the side plates, thereby ensuring the shading and sealing performance; the wire winding wheel 4 is in the shape of a cylindrical barrel, with its axis horizontal and parallel to the transverse extension direction of the louver curtain 3; one end of the suspension rope 5 is fixedly connected to the wire winding wheel 4, and the other end passes through each folding blade of the louver curtain 3 and then is connected to the lowermost end of the louver curtain 3; an opening for the suspension rope 5 to pass through is arranged on the bottom surface of the frame body 2; the wire winding wheel 4 and the suspension rope 5 are arranged in two groups and are balancedly arranged corresponding to the length direction of the louver curtain 3; the driving component drives the wire winding wheel 4 to rotate spirally, so that the suspension rope 5 is wound and unwound on the wire winding wheel 4 in a spiral winding shape; the photovoltaic panel 6 is vertically arranged in the photovoltaic area, and its light-absorbing surface corresponds to the side of the insulating glass 1 facing the outdoor, that is, corresponding to the light-transmitting area, which is convenient for receiving sunlight; the power control unit 7 includes a control switch and a power supply. The control switch is electrically connected to the photovoltaic panel 6 through a wire. The power supply can preferably be a lithium battery, and the lithium battery is detachably installed on the control switch. The power control unit 7 is located outside the insulating glass 1 and corresponds to the side of the insulating glass 1 facing the indoor, thereby facilitating operation and battery replacement and realizing all-weather operation; preferably, a wireless receiver is integrated on the power control unit 7 and can be connected to the grid for intelligent control. In the actual use of this technical solution, by arranging the photovoltaic panel 6 and the power control unit 7, while integrating the louver curtain 3 inside the insulating glass 1 to achieve the sunshade function, the solar light can also be used for energy storage, and then supply energy to the driving component. When needed, the wire winding wheel 4 is driven to rotate to realize the electric control lifting and adjustment of the louver curtain 3, which facilitates the use. In addition, the spiral rotation function of the wire winding wheel 4 makes the suspension rope 5 wind and unwind in a spiral shape, avoiding the problems of unstable winding and unwinding or jamming caused by mutual contact and compression of the suspension ropes 5 during winding.

[0039] Compared with the prior art, the photovoltaic electric device with built-in insulating glass proposed in the embodiment of the present invention can integrate the venetian blinds 3 into the inner side of the insulating glass 1 to achieve the sunshade function by setting a photovoltaic panel 6 and a power control unit 7. At the same time, it can also utilize sunlight to store energy, and then supply energy to the driving component. When needed, it drives the take-up wheel 4 to rotate to achieve the electrically controlled lifting and lowering adjustment of the venetian blinds 3, which is convenient for use. In addition, the spiral rotation function of the take-up wheel 4 allows the hanging rope 5 to be spirally wound and retracted, avoiding the problem of unstable retraction or adhesion caused by the mutual contact and pressure of the hanging rope 5 when winding.

[0040] In another embodiment proposed by the present invention, the driving assembly includes a motor 8 installed in the frame 2, the output end of the motor 8 is coaxially connected to the driving shaft 9, the take-up wheel 4 is coaxially connected to the driving shaft 9 for synchronous rotation, and the take-up wheel 4 can move axially on the driving shaft 9, and a threaded assembly is provided in the frame 2 for making the take-up wheel 4 move axially synchronously when rotating. Specifically, the motor 8 is electrically connected to the circuit composed of the photovoltaic panel 6 and the power control unit 7, and is controlled to start and stop by the power control unit 7; the driving shaft 9 is preferably a polygonal prism, and further preferably a hexagonal aluminum rod; the axis of the take-up wheel 4 is provided with a polygonal prism-shaped through groove matching the driving shaft 9, thereby ensuring that the take-up wheel 4 and the driving shaft 9 rotate synchronously, and the take-up wheel 4 can move axially; the setting of the threaded assembly realizes that the take-up wheel 4 rotates and moves axially at the same time, that is, the take-up wheel 4 rotates spirally, and under the condition that the suspension position of the suspension rope 5 connected to the blind 3 does not change significantly, the take-up wheel 4 can realize the spiral winding of the suspension rope 5 through spiral rotation.

[0041] As the preferred technical solution of this embodiment, the threaded assembly includes a sleeve 10 coaxially sleeved outside the driving shaft 9 and coaxially fixedly connected to one end of the take-up wheel 4. A threaded ring 11 is threadedly sleeved on the outer side of the sleeve 10, and the threaded ring 11 is fixedly connected to the frame 2. Specifically, when the take-up wheel 4 rotates to reel in the direction of the lifting rope 5, the corresponding sleeve 10 rotates and the threaded ring 11 produces a threaded feeding effect, causing the axial movement of the take-up wheel 4, so that the part without the rope 5 is close to the vertical suspension position of the rope 5, thereby continuously spirally winding and reeling in the rope 5. Conversely, when the take-up wheel 4 rotates to release the rope 5, the take-up wheel 4 approaches the vertical suspension position of the rope 5 with the part with the rope 5, thereby continuously spirally releasing the rope 5.

[0042] In another embodiment proposed by the present invention, a scraper rod 12 is rotatably arranged on the outside of the light-transmitting area, and the drive shaft 9 is linked to the scraper rod 12 through a linkage assembly. Specifically, the rotating shaft of the scraper rod 12 is set in the middle position on the upper side of the light-transmitting area; the scraper rod 12 is used to scrape the surface of the light-transmitting area, thereby achieving cleaning, ensuring the light transmittance of the light-transmitting area when it is clean, and then maintaining the efficiency of the photovoltaic panel 6 in receiving sunlight.

[0043] As the preferred technical solution of this embodiment, the linkage assembly includes a linkage shaft 13 linked to the drive shaft 9, one end of the linkage shaft 13 is coaxially connected to an eccentric rocker 14, the rotating shaft of the scraper rod 12 is elastically rotatable and arranged inside the frame 2 and one end is coaxially connected to a gear 15, the gear 15 is meshed and connected to a rack 16, and a linkage member 17 is provided at the lower end of the rack 16. The lifting movement of the linkage member 17 is arranged in the range of movement of the eccentric rocker 14. Specifically, the axial direction of the linkage shaft 13 is parallel to the drive shaft 9, and the linkage shaft 13 is located on the upper side of the drive shaft 9; the linkage shaft 13 is driven to rotate by the drive shaft 9; the extension direction of the rod portion of the eccentric rocker 14 is parallel to the axial direction of the linkage shaft 13, and is arranged deviating from the axis center of the linkage shaft 13, thereby the eccentric rocker 14 is moved along When the linkage shaft 13 rotates, the eccentric rocker 14 performs a circular motion; the elastic rotation of the scraper rod 12 enables it to automatically maintain its position when it is not subjected to force. In this position, the corresponding scraper rod 12 does not block the light-transmitting area and is located on the upper side of the light-transmitting area; the rack 16 is arranged in the frame 2 for lifting and lowering movement; the rack 16 is arranged on the side of the linkage shaft 13 away from the scraper rod 12, and the linkage member 17 is horizontally approached from the lower end of the rack 16 to the axis of the eccentric rocker 14, and extends to the vertical plane corresponding to the axis of the eccentric rocker 14. The linkage member 17 is rod-shaped and points to the axis of the vertical eccentric rocker 14; the height of the linkage member 17 when it is free and stationary is lower than the maximum height reached by the rotation of the eccentric rocker 14, and is near this height. This is the initial height of the linkage member 17. When the eccentric rocker 14 rotates above the height of its axis, it moves from the direction away from the linkage member 17 to the direction close to the linkage member 17, thereby first moving to the top of the linkage member 17, and then dragging the linkage member 17 downward to descend together, and the linkage member 17 drives the rack 16 to descend, and the rack 16 rotates the rotating shaft of the scraper rod 12 through the gear 15. The scraper rod 12 resists the elastic rotation, and the rotation direction of the scraper rod 12 at this time can make it scrape downward through the light-transmitting area, and then continue to rotate with the eccentric rocker 14. The eccentric rocker 14 leaves the linkage member 17, and the scraper rod 12 rotates under the elastic rotation restoring force, and the linkage member 17 is correspondingly linked back to the initial height, thus completing the cycle.

[0044] As the preferred technical solution of this embodiment, the rotating shaft of the scraper rod 12 is connected to the elastic cavity 19 set in the frame 2 through the coil spring 18. Specifically, the coil spring 18 limits the rotation of the scraper rod 12, so that the scraper rod 12 automatically remains on the upper side of the non-blocking light-transmitting area.

[0045] As the preferred technical solution of this embodiment, a first synchronous wheel 20 is coaxially fixedly connected to the drive shaft 9, and a second synchronous wheel 21 is coaxially fixedly connected to the linkage shaft 13. The first synchronous wheel 20 and the second synchronous wheel 21 are connected by a synchronous belt 22. Specifically, the drive shaft 9 drives the synchronous belt 22 to roll through the first synchronous wheel 20, and the synchronous belt 22 drives the second synchronous wheel 21 to rotate, and the second synchronous wheel 21 drives the linkage shaft 13 to rotate.

[0046] As a preferred technical solution of this embodiment, a swing arm 23 is hinged on the drive shaft 9, and the linkage shaft 13 is rotatably connected to the swing arm 23. Under the rotation of the swing arm 23, the linkage shaft 13 has a first position and a second position located on the upper and lower sides of the drive shaft 9. When the linkage shaft 13 is in the first position, the eccentric rocker 14 toggles the linkage member 17 during the rotation process, and when the linkage shaft 13 is in the second position, the eccentric rocker 14 toggles the suspension rope 5 during the rotation process. Specifically, the swing arm 23 is used to limit the relative position between the drive shaft 9 and the linkage shaft 13, and also to keep the synchronous belt 22 taut; during the rotation friction and Under inertia, when the driving shaft 9 rotates, it will drive the swing arm 23 to rotate, and the swing arm 23 drives the linkage shaft 13 to rotate around the driving shaft 9; when the linkage shaft 13 is in the first position, the linkage shaft 13 corresponds to the upper side of the driving shaft 9, and the driving shaft 9 drives the linkage shaft 13 to switch to the rotation direction in the first position through the swing arm 23, and the corresponding driving shaft 9 drives the take-up wheel 4 to rotate to reel in the line; when the linkage shaft 13 is in the second position, the linkage shaft 13 corresponds to the lower side of the driving shaft 9, and the driving shaft 9 drives the linkage shaft 13 to switch to the rotation direction in the second position through the swing arm 23, and the corresponding driving shaft 9 drives the take-up wheel 4 to rotate to release the line. In actual use, when the driving shaft 9 rotates to make the take-up wheel 4 take up the wire to retract the blinds 3, the swing arm 23 will drive the linkage shaft 13 to rotate to the first position first, and then the linkage shaft 13 will remain in the first position. At this time, the driving shaft 9 continues to rotate, and the linkage shaft 13 rotates through the first synchronous wheel 20, the synchronous belt 22 and the second synchronous wheel 21. The linkage shaft 13 drives the eccentric rocker 14 to rotate to interact with the linkage member 17, thereby realizing the automatic scraping of the light-transmitting area by the scraper 12, thereby achieving the cleaning function of the light-transmitting area; and when the driving shaft 9 rotates to make the take-up wheel 4 take up the wire When the venetian blind 3 is unwound by unwinding, the swing arm 23 drives the linkage shaft 13 to rotate to the second position first, and then the linkage shaft 13 remains in the second position. At this time, the driving shaft 9 continues to rotate, and the linkage shaft 13 rotates in conjunction with the first synchronous wheel 20, the synchronous belt 22 and the second synchronous wheel 21. The linkage shaft 13 drives the eccentric rocker 14 to rotate to continuously move the hanging rope 5. The hanging rope 5 vibrates and keeps unwinding smoothly, thereby preventing the hanging rope 5 from sticking to the take-up wheel 4 or getting stuck. This realizes the automatic risk elimination function and maintains the long-term normal retraction and unfolding of the venetian blind 3.

[0047] As the preferred technical solution of this embodiment, the position switching of the linkage shaft 13 is achieved by driving the swing arm 23 with damping through the drive shaft 9. Specifically, the driving shaft 9 driving the swing arm 23 with damping can be derived from the rotational friction of the swing arm 23 on the drive shaft 9, as well as the transmission friction of the first synchronous wheel 20, the second synchronous wheel 21 and the synchronous belt 22; the inner wall of the frame 2 is fixedly provided with a first leaning member 24 and a second leaning member 25 for positioning the first position and the second position of the linkage shaft 13 respectively; the first leaning member 24 is arranged on the side of the linkage shaft 13 away from the scraper rod 12 in the first position, and the second leaning member 25 is arranged on the lower side of the linkage shaft 13 in the second position, and the linkage shaft 13 is limited to continue to move in the direction away from the scraper rod 12, so that the linkage shaft 13 is limited to rotate around the drive shaft 9 between the first leaning member 24 and the second leaning member 25. When the linkage shaft 13 is against the first leaning member 24 or the second leaning member 25 as the drive shaft 9 rotates, the drive shaft 9 continues to rotate and drives the linkage shaft 13 to rotate in the same direction.

[0048] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
