Abstract
Description
Technical Field
[0001] This utility model belongs to the field of insulated glass technology, and in particular relates to a large-format photovoltaic integrated insulated glass with built-in blinds. Background Technology
[0002] Built-in blinds can now be installed inside insulated glass units, offering advantages such as sound insulation, heat insulation, low energy consumption, and strong privacy. Compared to external blinds, they also boast longer lifespan, greater stability, and better dustproofing. Similarly, photovoltaic panels can be integrated into the blinds, generating electricity during shading, as illustrated in the utility model patent application number 202222097813.X. This further enhances practicality, convenience, and energy efficiency.
[0003] However, for the use of large-format insulated glass, the glass is long and tall. If built-in photovoltaic louvers are installed in the hollow cavity, the length and number of louver blades will be large. The existing louver device drive components and transmission system will have a problem of being unable to drive due to the large load. At the same time, due to the narrow and limited space of the glass profile and the hollow cavity, it is not possible to use large-volume drive or arrange a large number of drive.
[0004] Therefore, designing a built-in louver device suitable for large-format insulated glass is a problem that needs to be solved by those skilled in the art. Summary of the Invention
[0005] The purpose of this invention is to provide a large-format photovoltaic integrated insulated glass unit with built-in blinds. By designing a novel blind device, it can be divided into multiple modular blind modules. Each blind module can independently control the rotation of its blades, thereby controlling the opening and closing of the shading mechanism. Through the design of the drive shaft, hollow shaft, electromagnetic coupling, and brake disc, the rolling and unrolling of the blinds can be controlled separately. The rolling drive is applied to the control of a single blind module, and a small-scale drive can meet the usage requirements, avoiding the problem of the large weight of the blinds corresponding to the large-format insulated glass unit causing the inability to drive them, and meeting the installation requirements of confined spaces.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a large-format photovoltaic integrated hollow glass with built-in louvers, including hollow glass and louver device, wherein the louver device is disposed in the hollow cavity of hollow glass.
[0008] The louver device includes a drive shaft and several louver shafts, and louver blinds are connected to the louver shafts.
[0009] One end of the drive shaft is connected to a drive unit, and several bearing seats are linearly arranged on the drive shaft. The drive unit and the bearing seats are fixed inside the top profile of the insulating glass.
[0010] The louvered shaft is a hollow shaft, and several louvered shafts are linearly sleeved on the drive shaft. A gap is formed between two adjacent louvered shafts, and an electromagnetic coupling is provided between one end of the louvered shaft and the drive shaft at the gap.
[0011] A brake disc is fixed to the circumferential side of the other end of the louver shaft, and several electronically controlled calipers are linearly fixed inside the top profile of the insulating glass. The several electronically controlled calipers are respectively engaged with the brake discs on the several louver shafts.
[0012] Both ends of the louver shaft are fixed with wire reels;
[0013] The venetian blind includes several linearly distributed blades, each blade being a photovoltaic panel structure. A fixing rope is fixed between the rear sides of both ends of the blades, and the top of the fixing rope is fixed to the top profile of the insulating glass. A flipping rope is fixed between the front sides of both ends of the blades, and an electric pull rod is provided between the top of the flipping rope and the top profile of the insulating glass.
[0014] The bottom blades of the venetian blind are each fixed with a lifting rope at both ends, and the remaining blades are provided with clearance openings at both ends. The lifting ropes pass through the clearance openings and are connected to the reel.
[0015] Furthermore, the blades on several of the venetian blinds correspond one-to-one, and a micro-slit is formed between the ends of the blades of two adjacent venetian blinds.
[0016] Furthermore, the electromagnetic coupling includes a driving end and a driven end, the driving end being fixed on the transmission shaft at the interval, and the driven end being fixed on the end of the louver shaft.
[0017] Furthermore, the bearing housing on the drive shaft is located at the interval between two adjacent louvered shafts, and the bearing housing is offset from the electromagnetic coupling.
[0018] Furthermore, the drive includes a reducer, one end of the transmission shaft is connected to the output end of the reducer, a motor is fixed on the reducer, the motor is connected to the input end of the reducer, and an encoder is provided on the output end of the motor.
[0019] Furthermore, the fixing rope is a cable structure, and several of the blades are electrically connected to the fixing rope. The top profile of the insulating glass is provided with a busbar connected to several fixing ropes.
[0020] This utility model has the following beneficial effects:
[0021] This invention features a novel louver device that can be divided into multiple modular louver modules. Each louver module can independently control the rotation of its blades, thereby controlling the opening and closing of the shading mechanism. Through the design of a drive shaft, hollow shaft, electromagnetic coupling, and brake disc, the louver's winding and unwinding can be controlled separately. The winding drive is applied to the control of a single louver module, and a small-scale drive is sufficient to meet the usage requirements. This avoids the problem of large-format hollow glass panels being unable to drive due to the weight of the louvers, and meets the installation requirements of confined spaces.

[0037] The Venetian blind 4 includes several linearly distributed blades 401. The blades 401 are photovoltaic panel structures. A fixing rope 402 is fixed between the rear sides of both ends of the several blades 401. The top of the fixing rope 402 is fixed to the top profile of the insulating glass. A flip rope 403 is fixed between the front sides of both ends of the several blades 401. An electric pull rod 404 is provided between the top of the flip rope 403 and the top profile of the insulating glass.
[0038] The bottom blades 401 of the Venetian blind 4 are fixed with lifting ropes 405 at both ends, and the remaining blades 401 are provided with clearance openings 406 at both ends. The lifting ropes 405 pass through the clearance openings 406 and are connected to the reel 302.

[0045] The working principle of this utility model is as follows:
[0046] Initial state reference Figure 1-3 As shown, the Venetian blinds are in the open position;
[0047] Scenario 1: If you want to control the light blocking of a single Venetian blind 4, start the electric pull rod 404 corresponding to Venetian blind 4, pull the flip rope 403 to raise it a certain distance while keeping the fixed rope 402 stationary, so that the slats 401 of Venetian blind 4 flip to block the light.
[0048] Scenario 2: If you want to control all Venetian blinds 4 to block light, control all Venetian blinds 4 simultaneously using the method in Scenario 1.
[0049] Scenario 3: To control the lifting of one Venetian blind 4, first control the electromagnetic coupling 5 corresponding to Venetian blind 4 to close, connecting the veil shaft 3 to the drive shaft 2, while the other veil shafts 3 are separated from the drive shaft 2. Then, control the electric clamp 6 corresponding to the veil shaft 3 to open, separating the veil shaft 3 from the profile. By starting the drive 201, the drive shaft 2 is rotated at a certain angle (the rotation angle is determined by the encoder), which in turn drives the lifting rope 405 to rise, lifting the bottommost blade 401 (the lifting rope 405 is coiled inside the reel 302). This achieves the stacking and lifting of the blades 401 from bottom to top. After the lifting is complete, control the corresponding electric clamp 6 to cooperate with the brake disc 301 to achieve a tight fit, and control the electromagnetic coupling 5 to open and the drive 201 to reverse and reset.
[0050] Scenario 4: If it is necessary to control the rolling up of all Venetian blinds 4 or several corresponding Venetian blinds 4, the Venetian blinds 4 shall be rolled up and retracted in sequence according to the control method in Scenario 3.
