Description

Technical Field

[0001] The present invention relates to the technical field of sunshades, and particularly 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 difficult to dissipate heat. Therefore, the prior art adopts the method of installing sunshades to improve this problem.

[0003] Patent document CN102352723A discloses an insulating glass with a built-in sunshade on the publication date of February 15, 2012, which includes two glass media, a sunshade between the two glass media, a traction mechanism for controlling the sunshade, and a traction device fixed on the traction mechanism; outside the insulating glass, an operating device is provided opposite to the traction device; at least one of the operating device and the traction device contains magnetic materials, and the two are magnetically connected; at least one of the operating device and the traction device includes a first support structure, a first rotating shaft is fixed on the first support structure, and a roller with a resistance position is installed on the first rotating shaft. In one rotation cycle of the roller, at least two or more contact positions with the insulating glass are closest to the first rotating shaft. Due to the selection of the roller with a resistance position, when the sunshade stops moving, it is not only affected by the frictional force of the contact surface but also regulated by the horizontal component force of the magnetic force, having an automatic limit function, reducing the operation difficulty, and improving the operation feel.

[0004] Integrating the retractable sunshade into the insulating glass isolates the structure of the retractable suspension ropes in the insulating glass. The existing retractable structures will stack and wind the suspension ropes, which is likely to cause unstable retraction and release. Moreover, if the suspension ropes on one side stick together, it will cause the curtain to tilt and then get stuck, seriously affecting 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

Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0037] Please refer to 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, with a louver curtain 3 arranged on its lower side; a wire winding wheel 4 movably arranged inside the frame body 2, and the outer wall is connected to the louver curtain 3 through a lifting rope 5; a driving assembly for driving the wire winding wheel 4 to rotate spirally; a photovoltaic panel 6 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 arranged outside the insulating glass 1 and electrically connected to the photovoltaic panel 6, for storing the electricity generated by the photovoltaic panel 6 to supply energy to the driving assembly.

[0038] Specifically, the frame body 2 is composed of multiple components spliced together, and inside it forms a wire winding area for arranging the wire winding structure and a photovoltaic area for arranging the photovoltaic panel 6; the insulating glass 1 includes double-layer glass sandwiching 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 two opposite sides of the louver curtain 3 are embedded in the side plates, thereby ensuring light-shielding and sealing properties; the wire winding wheel 4 is in the shape of a cylindrical tube, with its axis horizontal and parallel to the transverse extension direction of the louver curtain 3; one end of the lifting 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 lifting rope 5 to pass through is arranged on the bottom surface of the frame body 2; the wire winding wheel 4 and the lifting rope 5 are arranged in two groups and are balancedly arranged corresponding to the length direction of the louver curtain 3; the driving assembly drives the wire winding wheel 4 to rotate spirally, so that the lifting 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 source, the control switch is electrically connected to the photovoltaic panel 6 through a wire, the power source can preferably be a lithium battery, the lithium battery is detachably installed on the control switch, the power control unit 7 is outside the insulating glass 1 and corresponds to the side of the insulating glass 1 facing the indoor, thereby being convenient for operation and convenient for battery replacement to achieve all-weather operation; preferably, a wireless receiver is integrated on the power control unit 7, and it can be connected to the grid for intelligent control. In the actual use of this technical solution, by setting the photovoltaic panel 6 and the power control unit 7, while integrating the louver curtain 3 inside the insulating glass 1 to achieve the shading function, it can also store energy using sunlight, and then supply energy to the driving assembly, driving the wire winding wheel 4 to rotate when needed to achieve the electric control lifting and adjustment of the louver curtain 3, which is convenient for use. In addition, the spiral rotation function of the wire winding wheel 4 makes the lifting rope 5 wind and unwind in a spiral shape, avoiding the problems of unsteady winding and unwinding or sticking and jamming during winding and unwinding caused by the mutual contact and compression of the lifting ropes 5 when they are wound.

[0039] Compared with the prior art, a photovoltaic electric device with built-in insulating glass proposed by an embodiment of the present invention, by providing a photovoltaic panel 6 and a power control unit 7, while integrating the louver curtain 3 inside the insulating glass 1 to achieve the sunshade function, can also store energy using sunlight, and then supply energy to the driving assembly, driving the wire reel 4 to rotate when needed to achieve the electric control lifting adjustment of the louver curtain 3, which is convenient for use. In addition, the spiral rotation function of the wire reel 4 makes the lifting rope 5 wind and unwind in a spiral shape, avoiding the problems of unstable winding and unwinding or sticking and jamming caused by the mutual contact and compression of the lifting ropes 5 during winding.

[0040] In another embodiment proposed by the present invention, the driving assembly includes a motor 8 installed inside the frame 2. The output end of the motor 8 is coaxially connected with a driving shaft 9. The wire reel 4 is coaxially connected to the driving shaft 9 to rotate synchronously, and the wire reel 4 can axially move on the driving shaft 9. A threaded assembly for axially moving the wire reel 4 synchronously when it rotates is provided inside the frame 2. 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 multi-prismatic, and more preferably a hexagonal aluminum rod; a multi-prismatic through groove matching the driving shaft 9 is opened at the axis center of the wire reel 4, thereby satisfying the synchronous rotation of the wire reel 4 and the driving shaft 9, and the wire reel 4 can axially move; the setting of the threaded assembly realizes the axial movement of the wire reel 4 while rotating, that is, the wire reel 4 performs spiral rotation. Then, under the condition that the suspension position of the lifting rope 5 connecting the louver curtain 3 does not change greatly, the wire reel 4 can realize the spiral winding and unwinding of the lifting rope 5 through spiral rotation.

[0041] As a preferred technical solution of this embodiment, the threaded assembly includes a sleeve 10 coaxially sleeved outside the driving shaft 9 and coaxially and fixedly connected to one end of the wire reel 4. A threaded ring 11 is threadedly sleeved outside the sleeve 10, and the threaded ring 11 is fixedly connected inside the frame 2. Specifically, the rotation direction of the wire reel 4 for winding up the lifting rope 5 corresponds to the threaded feed action between the sleeve 10 and the threaded ring 11 when the sleeve 10 rotates, causing the axial movement of the wire reel 4, so that the part of the wire reel 4 without the lifting rope 5 wound thereon approaches the vertical suspension position of the lifting rope 5, thereby continuously winding up the lifting rope 5 in a spiral shape. On the contrary, when the wire reel 4 rotates to release the lifting rope 5, the part of the wire reel 4 with the lifting rope 5 wound thereon approaches the vertical suspension position of the lifting rope 5, thereby continuously spirally releasing the lifting rope 5.

[0042] In another embodiment proposed by the present invention, a scraping rod 12 is rotatably provided outside the light-transmitting area. The driving shaft 9 is linked with the scraping rod 12 through a linkage assembly. Specifically, the rotating shaft of the scraping rod 12 is arranged at the middle position on the upper side of the light-transmitting area; the scraping rod 12 is used for scraping the surface of the light-transmitting area, thereby achieving cleaning, ensuring the light transmittance under the condition of a clean light-transmitting area, and further maintaining the sunlight receiving efficiency of the photovoltaic panel 6.

[0043] As a 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 with an eccentric rocker 14. The rotating shaft of the scraping rod 12 is elastically rotatably arranged inside the frame 2 and one end is coaxially connected with a gear 15. The gear 15 is meshed with a rack 16. A linkage member 17 is arranged at the lower end of the rack 16. The linkage member 17 is arranged to move up and down within the moving range of the eccentric rocker 14. Specifically, the axial direction of the linkage shaft 13 is parallel to that of the drive shaft 9, and the linkage shaft 13 is located above the drive shaft 9; the linkage shaft 13 is driven to rotate by the drive shaft 9; the extending direction of the rod part of the eccentric rocker 14 is parallel to the axial direction of the linkage shaft 13 and is offset from the axis of the linkage shaft 13. Thus, when the eccentric rocker 14 rotates with the linkage shaft 13, the eccentric rocker 14 performs a circular motion; the elastic rotation of the scraping rod 12 enables it to automatically maintain its position when not under force. In this position, the corresponding scraping rod 12 does not block the light-transmitting area and is on the upper side of the light-transmitting area; the rack 16 is arranged to move up and down within the frame 2; the rack 16 is arranged on the side of the linkage shaft 13 away from the scraping rod 12. The linkage member 17 approaches the axis of the eccentric rocker 14 horizontally from the lower end of the rack 16 and extends to the vertical plane corresponding to the coincidence with the axis of the eccentric rocker 14. The linkage member 17 is rod-shaped and is arranged with its direction perpendicular to the axis of the eccentric rocker 14; the height of the linkage member 17 when freely 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 its axis height, it moves from the direction away from the linkage member 17 to the direction close to the linkage member 17. Thus, it can first move above the linkage member 17 and then drag the linkage member 17 down together. The linkage member 17 drives the rack 16 to descend. The rack 16 drives the rotating shaft of the scraping rod 12 to rotate through the gear 15. The scraping rod 12 resists the elastic rotation force, and the rotation direction of the scraping rod 12 at this time enables it to scrape down through the light-transmitting area. Then, as the eccentric rocker 14 continues to rotate, when the eccentric rocker 14 moves away from the linkage member 17, the scraping rod 12 rotates back under the elastic rotation restoring force, and the linkage member 17 correspondingly returns to the initial height. In this way, the cycle can be completed.

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

[0045] As a preferred technical solution of this embodiment, a first synchronous pulley 20 is coaxially and fixedly connected to the drive shaft 9, and a second synchronous pulley 21 is coaxially and fixedly connected to the linkage shaft 13. The first synchronous pulley 20 and the second synchronous pulley 21 are connected through a synchronous belt 22. Specifically, the drive shaft 9 drives the synchronous belt 22 to roll through the first synchronous pulley 20. The synchronous belt 22 drives the second synchronous pulley 21 to rotate, and the second synchronous pulley 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 a preferred technical solution of this embodiment, the position switching of the linkage shaft 13 is realized by driving the swing arm 23 to rotate with damping by the driving shaft 9. Specifically, the driving of the swing arm 23 with damping by the driving shaft 9 can be derived from the rotational friction of the swing arm 23 on the driving shaft 9, as well as the transmission friction of the first synchronous pulley 20, the second synchronous pulley 21 and the synchronous belt 22; 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 are fixedly arranged on the inner wall of the frame body 2; the first leaning member 24 is arranged on the side of the linkage shaft 13 away from the scraping rod 12 at the first position, and the second leaning member 25 is arranged on the lower side of the linkage shaft 13 at the second position, and limits the linkage shaft 13 from continuing to move in the direction away from the scraping rod 12. The above limits the rotation of the linkage shaft 13 around the driving shaft 9 between the first leaning member 24 and the second leaning member 25. When the linkage shaft 13 abuts against the first leaning member 24 or the second leaning member 25 as it rotates with the driving shaft 9, the driving shaft 9 continues to rotate and drives the linkage shaft 13 to rotate in the same direction.

[0048] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
