Description

Technical Field

[0001] This utility model relates to the field of electrochromic glass technology, specifically to an organic electrochromic laminated glass. Background Technology

[0002] Organic electrochromic laminated glass, as a core functional material for intelligent building envelopes, directly determines the building's lighting comfort, thermal performance, and energy efficiency through its optical control precision and long-term stability.

[0003] However, the current research and industrialization of organic electrochromic laminated glass for buildings still has certain shortcomings. Existing organic electrochromic films are prone to chemical degradation and physical deformation under extreme environments such as high and low temperature cycling and ultraviolet radiation, resulting in a narrowing of the dynamic range of transmittance and reduced cycle durability, making it difficult to meet the long-term service requirements of building windows. Moreover, due to the difference in the coefficients of thermal expansion between the glass substrate, the electrochromic film, and the interlayer material, interface delamination and microcracks are easily generated under alternating temperature and humidity stress, weakening impact resistance, and the edge encapsulation reliability is insufficient, posing a risk of functional layer leakage. In addition, traditional drive systems rely on fixed voltage regulation modes, which cannot match the changes in light intensity and indoor heat load in real time, resulting in excessively long coloring or fading conversion times and high energy consumption, restricting the implementation of intelligent light and heat control scenarios in buildings.

[0004] Therefore, this invention provides an organic electrochromic laminated glass that solves the above-mentioned problems. Utility Model Content

[0016] Beneficial effects

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1-4 An organic electrochromic laminated glass includes a structural layer, which includes a first glass substrate 1, a barrier layer 2, a core electrochromic layer 3, an intermediate adhesive layer 4, and a second glass substrate 5 arranged sequentially from the inside to the outside. A mounting groove is reserved at the edge of the first glass substrate 1.

[0027] Edge composite sealing structure 6, which is wrapped around the edge of the structural layer;

[0028] Drive control module 8 is installed in the mounting slot;

[0029] Monitoring layer 7 is installed in the non-transparent area on the outer edge of the second glass substrate 5;

[0030] Through the design of a multi-layered composite structure, the material's conductivity, environmental stability, and interface compatibility are synergistically optimized, ensuring that the thin film maintains a stable dynamic range of transmittance under harsh environments such as long-term ultraviolet irradiation and alternating temperature and humidity. The edge composite sealing structure 6 is used to block the permeation path of water vapor or oxygen, solving the problem of hydrolytic failure in humid water. It also uses expanded microspheres to adaptively compensate for thermal expansion and contraction, avoiding edge warping and improving overall sealing performance. The drive control module 8 is used to provide precise and low-energy driving voltage to achieve intelligent regulation. The monitoring layer 7 is used to collect multi-dimensional data such as light intensity and temperature in real time to monitor the glass's operating status and provide a data model for the adaptive regulation algorithm.

[0031] In some embodiments, such as Figure 2 As shown, the core electrochromic layer 3 is composed of viologen derivatives, inorganic nano-tungsten oxide and ionic liquid. The ionic liquid forms a three-dimensional ionic conductive network inside the core electrochromic layer 3.

[0032] Viologen derivatives, as intrinsically electrochemical active phases, undergo reversible redox reactions. Changes in their molecular structure lead to alterations in their absorption or transmission characteristics of visible light. Inorganic nano-tungsten oxide, as a charge transport enhancement phase, has a rigid framework that inhibits the thermal motion of viologen derivative molecular chains, preventing structural distortion under high and low temperature cycling, while simultaneously accelerating the charge transfer rate. Combined with a three-dimensional ion-conducting network, this significantly improves the uniformity and rate of color change response.

[0033] In some embodiments, such as Figure 2 As shown, the edge composite sealing structure 6 includes, from the inside out, an interface anchoring layer, a main sealing barrier layer, and a gradient buffer layer. The contact interface between the gradient buffer layer and the main sealing layer and the outer protective layer all adopt a sawtooth transition.

[0034] The interface anchoring layer is a laser micro-melting alloy point. The laser micro-melting alloy point is arranged in a staggered quincunx pattern. The laser micro-melting alloy point is set at the edge joint of the three layers of the first glass substrate 1, the intermediate adhesive layer 4, and the second glass substrate 5.

[0035] The main sealing barrier layer is composed of weather-resistant two-component silicone sealant and expandable microspheres, with the thickness of the weather-resistant two-component silicone sealant being 1.5–2.0 mm.

[0036] The laser micro-fusion welding alloy points of the interface anchoring layer form physical anchoring points through metallurgical bonding, which strengthens the interface adhesion between the sealing structure and the glass substrate and the intermediate adhesive layer, and blocks the water vapor and oxygen penetration paths between the layers. The weather-resistant two-component silicone sealant of the main sealing barrier layer has a low water vapor permeability. The built-in expansion microspheres adapt to the volume expansion or contraction with extreme temperature changes, accurately compensating for the thermal expansion and contraction difference between the glass and the sealing layer, and avoiding edge warping or cracking. The serrated transition design of the contact interface between the gradient buffer layer and the main sealing layer and the outer protective layer absorbs thermal stress twice through geometric deformation, further reducing the risk of interface shear stress concentration.

[0037] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the drive control module 8 integrates a circuit unit, a control unit, and a communication unit; the control unit includes an edge computing chip and a lightweight neural network module; the communication unit is a low-power wireless communication module.

[0038] The monitoring layer 7 includes a light intensity sensor probe and an infrared thermal imager miniature probe, which are integrated into the four corner edges of the second glass substrate 5.

[0039] The drive control module 8 is used to provide a precise and low-energy drive voltage, which is conducted to the core electrochromic layer 3 through the FTO / ITO conductive layer of the first glass substrate 1, thereby realizing intelligent control. The monitoring layer 7 is used to collect multi-dimensional data such as light intensity and temperature in real time, monitor the glass operating status, and provide a data model for the adaptive control algorithm.

[0040] Working principle: In the initial state, the glass is in a natural fading state. At this time, the light transmittance of the core electrochromic layer 3 is at its maximum. At this time, the monitoring layer 7 continuously collects environmental data, and the drive control module 8 is in standby state.

[0041] When the monitoring layer 7 detects that parameters such as light intensity and temperature have reached the preset threshold, it immediately sends a signal to the drive control module 8. The drive control module 8 analyzes the data and generates a drive voltage command. The core electrochromic layer 3 will undergo an oxidation-reduction reaction under the action of the drive voltage, thereby achieving rapid coloring and blocking strong light and heat. When the environmental parameters are lower than the threshold, the drive control module 8 switches the voltage polarity 8, and the core electrochromic layer fades and restores light transmission.

[0042] The full-process edge composite sealing structure 6 can continuously block water vapor or oxygen and absorb thermal stress, ensuring the long-term stable operation of each component.
