Technical Field
[0001] This utility model relates to the field of louver technology, specifically to a dimming glass louver. Background Technology
[0002] Dimmable glass blinds are a new type of door / window / partition product that integrates mechanical structure adjustment and electronic dimming function. The core is to combine "rotatable blind structure" with "dimmable glass material". It retains the angle adjustment function of traditional blinds and has the controllable light transmittance of dimming glass, taking into account practicality, privacy and decoration. It is commonly found in office spaces, home living rooms, hotel partitions and other scenarios.
[0003] Traditional dimming glass louvers are mostly supported by a single horizontal plate or a few support columns at the bottom, without forming a multi-level load-bearing structure. When the louver body is heavy, such as with large glass blades, local stress concentration is likely to occur, leading to cracking or settlement of the lower frame and affecting the louver rotation accuracy. Utility Model Content
[0004] The purpose of this invention is to provide a dimming glass louver with the advantages of protection and load-bearing capacity, thus solving the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A dimming glass louver includes a louver body. A protective support assembly for sealing and protecting the louver body and for bearing load buffering is fixedly installed on the outside of the louver body by bolts. An outer protective window frame is fixedly installed on the outside of the protective support assembly by a snap-fit. The protective support assembly includes sealing and protective vertical strips fixedly installed on the front and rear ends of both sides of the outer protective window frame. An inclined sealing guide plate is integrally formed on the inner side of the two sets of sealing and protective vertical strips.
[0007] Preferably, a buffer protective horizontal plate is fixedly connected to the lower end of the louver body, and multiple sets of equidistantly distributed pressure-resistant support columns are fixedly installed at the lower end of the buffer protective horizontal plate.
[0008] It is worth noting that the buffer protection horizontal plate is made of EVA elastic material; however, it is important to note that the spacing of the pressure-resistant support columns needs to be calculated based on the weight of the louvers, generally between 8-12cm. If the spacing is too wide, the middle of the horizontal plate may sag, while if it is too narrow, it will increase the cost.
[0009] Preferably, a load-bearing partition is fixedly installed at the lower end of the compression support column, and pressure-distributing crossbars are fixedly installed on both sides of the lower end of the load-bearing partition.
[0010] It is worth noting that the pressure-distributing horizontal bars transfer the force of the load-bearing partition to the outer protective window frame in the horizontal direction, avoiding the concentration of force in a certain area and reducing the risk of local deformation of the window frame; however, it is important to note that the pressure-distributing horizontal bars must be in close contact with the inner wall of the window frame, otherwise the force transmission will be interrupted due to gaps, forming a new stress concentration point.
[0011] Preferably, a reinforcing anti-breakage pressure plate is fixedly installed at the lower end of the pressure-dividing crossbar, and two sets of anti-collision mounting plates that are connected and assembled with the upper and lower inner walls of the outer protective window frame are fixedly installed at the lower end of the reinforcing anti-breakage pressure plate.
[0012] It is worth noting that the inside of the anti-collision mounting plate is covered with a rubber anti-collision pad; however, it is important to ensure that the connection method between the anti-collision mounting plate and the window frame is compatible with the window frame material, such as using clips, bolts, or other connection methods, to avoid loosening of the connection.
[0013] Preferably, the outer protective window frame includes two sets of first anti-deformation window frames installed on the outside of two sets of anti-collision mounting plates, and a second anti-deformation window frame is fixedly installed on the outside of the two sets of first anti-deformation window frames.
[0014] It is worth noting that the first anti-deformation window frame is made of aluminum alloy, while the second anti-deformation window frame is made of carbon steel. However, it is important to select the material combination according to the installation environment. For example, in coastal areas, an anti-rust coating should be added to prevent the carbon steel window frame from rusting.
[0015] Preferably, the louver body includes a control device installed on the inner wall of the second anti-deformation window frame. Multiple sets of louver blades are installed inside the control device. The louver blades are made of light-adjusting glass. The control device is used to drive the louver blades to rotate and adjust the light transmittance of the louver blades.
[0016] It is worth noting that the control device includes a stepper motor, a transmission gear set, and a dimming controller. The stepper motor is connected to multiple sets of louvers through the transmission gear set to drive the louvers to rotate within the range of 0°-120°. The dimming controller is electrically connected to the louvers through wires to adjust the light transmittance of the louvers. However, it is important to note that the motor power of the control device must match the total weight of the louvers to avoid overload and burnout.
[0017] Preferably, two sets of protective glass are fixedly installed on both the front and rear sides of the louver, located inside the control device, and an adjustment cavity is formed between the two sets of protective glass.
[0018] It is worth noting that: adjusting the cavity provides room for the louvers to rotate, avoiding friction with the protective glass; however, the edges of the protective glass should be chamfered to avoid scratching hands or seals during installation.
[0019] Preferably, sealing strips are fixedly installed on the upper and lower ends of the inner side of the control device, and the inclined angle of the oblique sealing guide plate is 30°-45°, which is used to guide the rainwater on the louver body downward and seal the gap between the louver body and the outer protective window frame.
[0020] It is worth noting that the sealing strip is made of silicone, and its inner side fits tightly against the edge of the protective glass to seal the gap between the regulating cavity and the outside world, preventing dust or moisture from entering the regulating cavity; however, it is important to ensure that the sealing strip fits tightly against the edge of the protective glass and avoid wrinkles during installation, otherwise leaks may occur.
[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] In this invention, the protective support component can not only prevent external dust and rainwater from entering the louver body, but also distribute the weight of the louver body and buffer external impacts, thereby improving the product's environmental adaptability and structural stability, and extending the service life of internal electronic components and mechanical parts. The outer protective window frame, as the outer frame of the entire product, bears the weight of the protective support component and the louver body, while providing physical protection for all internal components.

[0029] As an innovative category in the modern door, window, and partition industry, smart glass blinds break through the limitations of traditional single-function door and window products by deeply integrating mechanical structure adjustment and electronic dimming technology. They have become the preferred solution for office spaces, home living rooms, hotel partitions, and other scenarios. From a product positioning perspective, it is not simply a combination of two technologies, but rather a synergistic unity of "mechanical adjustment flexibility" and "electronic dimming intelligence" through precise structural design and functional adaptation. It not only continues the practical attribute of traditional blinds that control the direction of light incidence by adjusting the angle of the slats, but also incorporates the core characteristic of smart glass that changes light transmittance through changes in electric field or temperature. This allows the product to meet basic lighting needs while further taking into account privacy protection and decorative aesthetic expression.
[0030] In terms of functional integration, the advantages of this product are reflected in its multi-dimensional scenario adaptation. Taking office spaces as an example, staff can adjust the angle of the louvers according to different work states—during morning meetings, the louvers can be tilted to 45°, which can both introduce natural light and reduce energy consumption of artificial lighting, and avoid visual fatigue caused by direct sunlight on the screen. When processing confidential documents, the light transmittance of the louvers can be adjusted through the electronic control system, allowing the glass to switch from a transparent state to a semi-transparent or opaque state, achieving space isolation without the need for additional curtains, improving work efficiency while ensuring information security. In home living room scenarios, it can serve as a partition connecting the living room and balcony. During the day, adjusting the angle of the louvers can introduce soft natural light, creating a spacious and bright living atmosphere. At night, by reducing the light transmittance, it can block the view from the outside, creating a private leisure environment for family members. In hotel partition scenarios, its decorative and functional characteristics are particularly prominent. The dimming glass louvers with different textures can echo the overall decoration style of the hotel, while the flexible light transmission adjustment can meet the light and privacy needs of different areas such as guest rooms, lobby, and restaurant, enhancing the high-end quality of the hotel space.
[0031] From the perspective of the coordinated design of materials and structure, the core competitiveness of dimming glass blinds lies in the in-depth exploration of "practicality". The dimming glass material used for the blinds is usually ordinary float glass as the base material, with liquid crystal film or electrochromic material sandwiched in the middle. The light transmittance is switched by external circuit control. This material not only has the hardness and impact resistance comparable to ordinary glass, but also maintains a basic light-blocking effect when the power is off, avoiding the problem of the blinds not being able to stay in place after the power is off in traditional blinds. The mechanical adjustment structure achieves precise control of the louver rotation angle through precise gear transmission and motor control. The angle adjustment range can cover 0°-180° to meet the light control needs in different scenarios. At the same time, the stability design of the mechanical structure ensures that the blinds are not prone to jamming or loosening during long-term use, thus extending the product's service life.
[0032] However, traditional smart glass blinds still have significant shortcomings in their structural design, especially the design flaws in the lower support structure, which have become key factors affecting product performance and lifespan. In traditional solutions, the lower support often uses a simple structure with a single horizontal plate or a few support columns, without designing a multi-level load-bearing and load-bearing distribution system based on the weight characteristics and stress patterns of smart glass blinds. This design may temporarily meet the needs of small-area, lightweight blind products, but when the product is applied to large-area scenarios, such as floor-to-ceiling window blinds in office spaces or high partition blinds in hotel lobbies, the defects will become prominent.
[0033] From a stress analysis perspective, the weight per unit area of dimming glass louvers, due to the inclusion of a glass substrate and a functional film layer, is significantly greater than that of traditional plastic or aluminum alloy louver blades. As the number of louvers increases and the overall area expands, the total weight of the louver body increases significantly. At this point, the stress defects of the traditional lower support structure become particularly prominent: with a single horizontal support, the horizontal plate must bear the vertical pressure of the entire louver body, but the connection points between the horizontal plate and the frame are only at both ends. The pressure cannot be effectively distributed, easily forming a stress concentration area in the middle of the horizontal plate. After long-term use, the horizontal plate will bend and deform due to fatigue stress, and may even cause the screws connecting it to the frame to loosen. Movement and detachment; although the design of a few support columns can distribute the pressure to a certain extent, the distribution spacing of the support columns is too large and does not match the weight distribution of the louver body. As a result, some support columns have to bear pressure far exceeding the design load, while other areas are suspended due to lack of effective support. This uneven stress state will directly affect the rotation accuracy of the louvers. The louvers that should rotate synchronously will get stuck or misaligned due to slight deformation of the lower frame. Some louvers cannot be fully closed or opened, which not only affects the light control effect, but also aggravates the wear of the mechanical transmission structure and shortens the product's maintenance cycle and service life.
[0034] In a real-world application case, an office space installed a large area of traditional dimmable glass blinds. After six months of use, significant problems emerged: cracks appeared where the lower frame connected to the wall, some support columns bent due to excessive stress, causing noticeable noises when the blinds flipped, and the angle could not be precisely adjusted—even when attempting to fully close the blinds, gaps remained in some areas, failing to effectively block outdoor light; and when adjusting the light transmittance, due to the settlement of the lower frame, some blinds experienced poor electrical contact, resulting in inconsistent light transmittance, severely impacting the cleanliness and practicality of the office environment. Later repairs revealed that the lower support of the blinds consisted of only two 10mm diameter support columns without any auxiliary load-bearing structure. The total weight of the blinds was approximately 80kg, and the two support columns each had to withstand a vertical pressure of 40kg, far exceeding their design load of 25kg. Long-term overloading caused deformation of the support columns, leading to the structural failure of the entire lower frame.
[0035] Furthermore, the defects of traditional lower support structures can indirectly affect product safety and maintenance costs. When the lower frame cracks or settles due to stress concentration, if it is not repaired in time, the center of gravity of the louver body may shift, and in severe cases, there is even a risk of the entire louver falling off, posing a safety hazard to people and objects below. During the repair process, not only is it necessary to replace the deformed support structure, but also to recalibrate the louver's flip angle and circuit connections. The repair cycle is long and costly, causing unnecessary trouble and economic losses to users. In contrast, if a multi-level load-bearing distribution structure can be designed, through the synergistic effect of components such as buffer protective horizontal plates, multiple sets of pressure-resistant support columns, and load-bearing partitions, the weight of the louver body can be evenly distributed throughout the support system, which can effectively avoid stress concentration problems, improve the structural stability and service life of the product, and provide reliable protection for the application of large-area dimming glass louvers.
[0036] 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.
[0037] To address the issue of poor protective performance of existing louvered blinds, the following technical solution is proposed. Please refer to [link / reference needed]. Figure 1-5 ;
[0038] The dimming glass louver includes a louver body 1. A protective support assembly for sealing, protecting, and cushioning the louver body 1 is bolted to the outside of the louver body 1. An outer protective window frame 3 is fixedly installed to the outside of the protective support assembly via clips. The protective support assembly includes sealing and protective vertical strips 201 fixedly installed on both sides and at the front and rear ends of the outer protective window frame 3. An inclined sealing guide plate 202 is integrally formed on the inner side of the two sets of sealing and protective vertical strips 201. The lower end of the louver body 1 is fixed... A buffer protective horizontal plate 203 is fixedly connected. Multiple sets of equidistantly distributed compression support columns 204 are fixedly installed at the lower end of the buffer protective horizontal plate 203. A load-bearing partition plate 205 is fixedly installed at the lower end of the compression support column 204. Pressure-distributing horizontal bars 206 are fixedly installed on both sides of the lower end of the load-bearing partition plate 205. A reinforcing anti-breakage pressure plate 207 is fixedly installed at the lower end of the pressure-distributing horizontal bar 206. Two sets of anti-collision mounting plates 208 are fixedly installed at the lower end of the reinforcing anti-breakage pressure plate 207 and are connected to the upper and lower inner walls of the outer protective window frame 3 for assembly.
[0039] The outer protective window frame 3 includes two sets of first anti-deformation window frames 301 installed on the outside of two sets of anti-collision mounting plates 208. Second anti-deformation window frames 302 are fixedly installed on the outside of the two sets of first anti-deformation window frames 301. The louver body 1 includes a control device 101 installed on the inner wall of the second anti-deformation window frame 302. Multiple sets of louver blades 102 are installed inside the control device 101. The louver blades 102 are made of dimming glass. The control device 101 is used to drive the louver blades 102 to rotate and... The light transmittance of the louver 102 is adjusted. Two sets of protective glass 103 are fixedly installed on the front and back of the louver 102 inside the control device 101. An adjustment cavity is formed between the two sets of protective glass 103. Sealing baffles 104 are fixedly installed on the upper and lower ends of the inner side of the control device 101. The inclined angle of the oblique sealing guide plate 202 is 30°-45°, which is used to guide the rainwater on the louver body 1 downward and seal the gap between the louver body 1 and the outer protective window frame 3.
[0040] Working principle: Two sets of anti-collision mounting plates 208 are connected to the upper and lower inner walls of the outer protective window frame 3, which can enhance the connection stability between the outer protective window frame 3 and the internal components and avoid overall deformation caused by external impact; In the protective support component, the sealing and protective vertical strips 201 fixed on the front and rear ends of both sides of the outer protective window frame 3 seal and protect the side of the louver body 1. The inclined sealing guide plate 202 with an integral molding and an inclination angle of 30°-45° on its inner side can guide the rainwater on the surface of the louver body 1 to flow downward to prevent rainwater from seeping into the interior, and seal the gap between the louver body 1 and the outer protective window frame 3 to improve the overall sealing performance;
[0041] The buffer and protective horizontal plate 203 fixed at the lower end of the louver body 1 can initially buffer the vertical pressure on the louver body 1. Multiple sets of equidistant pressure-resistant support columns 204 at its lower end further disperse the pressure. The load-bearing partition plate 205 at the lower end of the pressure-resistant support column 204 evenly transmits the pressure to the pressure-distributing horizontal bars 206 on both sides. The pressure-distributing horizontal bars 206 then transmit the pressure to the anti-collision mounting plate 208 and the outer protective window frame 3 through the reinforced anti-breakage pressure plate 207, forming a complete load-bearing buffer system to prevent the louver body 1 from being damaged due to excessive load.
[0042] In terms of functional adjustment, the control device 101 inside the louver body 1 is installed on the inner wall of the second anti-deformation window frame 302. It can drive the multiple sets of light-adjusting glass louvers 102 installed on the inner side to rotate, so as to adjust the opening and closing degree of the louver. At the same time, the control device 101 can adjust the light transmittance of the louvers 102 to meet the light requirements of different scenarios. The two sets of protective glass 103 fixed to the front and rear of the louvers 102 inside the control device 101 not only provide front and rear protection for the louvers 102 to prevent the louvers 102 from being directly damaged by external forces, but also form an adjustment cavity between the two sets of protective glass 103 to provide space for the rotation of the louvers 102 and avoid friction between the louvers 102 and the protective glass 103.
[0043] The sealing strips 104 fixed at the upper and lower ends of the inner side of the control device 101 seal the gap between the inside of the control device 101 and the protective glass 103, further preventing dust, rainwater and other impurities from entering the adjustment cavity, ensuring the stable operation of the louver 102 and the control device 101, and finally realizing the integrated operation of the dimming glass louver for protection and functional adjustment through the synergistic effect of each part.
