Description

Technical Field

[0001] This utility model relates to the field of electric lift window technology, specifically an electric lift window with an airtight protective structure. Background Technology

[0002] In modern architecture, windows are not only important for lighting and ventilation, but also have a significant impact on the comfort and safety of the indoor environment. With the advancement of electrical technology, most existing windows adopt electric drive structures. Electric intelligent lift windows are a type of electric window. They achieve window raising and lowering through an electric drive mechanism and integrate intelligent control systems into home appliances. They aim to improve ventilation, lighting, safety, and convenience, and are widely used in high-end residences, villas, sunrooms, office buildings, and other scenarios.

[0003] Since lift windows are mostly installed on the side of the window frame in high-rise residential buildings, there are certain requirements for the airtightness of the window frame structure. For the closed side of the lift window, existing lift windows mostly use a simple edge strip sealing structure to seal and protect the closed side seam of the window frame. The contact between the window frame and the edge strip mainly relies on the elasticity of the edge strip itself, resulting in poor contact and sealing tightness. In windy and rainy weather, it is easy to cause water seepage and air leakage at the edge seam. Therefore, an electric lift window with an airtight protective structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an electrically operated lifting window with an airtight protective structure to solve the problems mentioned in the background art.

[0025] Example

[0026] Please see Figure 1-5 This utility model provides a technical solution: an electric lift window with an airtight protective structure, including a window body mechanism and a sealing mechanism. The window body mechanism includes a window frame base 1, a fixed window base 2, a movable window base 3, a lifting drive motor 4, and a drive screw 5. The fixed window base 2 is fixedly installed on the lower middle part of the window frame base 1 as a fixed window body structure for the lower part of the window body. Specifically, see attached... Figure 1 As shown, a support beam is horizontally fixedly installed in the middle of the window frame 1. The fixed window seat 2 is fixedly installed in the lower part of the inner frame of the window frame 1 by the support beam, and the support beam serves as a partition support structure in the middle of the window frame 1.

[0027] The movable window seat 3 is vertically mounted in the middle of the window frame seat 1, driven by a lifting drive motor 4 and a drive screw 5. See attached diagram for details. Figure 2As shown, to facilitate the connection and installation of the movable window seat 3, a lifting guide groove is provided on the inner frame edge of the window frame seat 1. The side seat of the movable window seat 3 is slidably fitted into the inner side of the lifting guide groove. The lifting drive motor 4 is a servo motor in the prior art. The lifting drive motors 4 are arranged in pairs. To improve the stability of the drive transmission, a reducer is provided on the drive side of both sets of lifting drive motors 4. The two sets of reducers are symmetrically fixed on both sides of the upper part of the window frame seat 1 by bolts. The rotating shaft end of the lifting drive motor 4 is fixedly installed with the drive input rotating shaft end of the reducer, which serves as the lifting mechanism for the movable window seat 3. The power input structure for the lowering mechanism includes a drive screw 5 for lifting and lowering the movable window seat 3. The drive screw 5 is vertically mounted on the outer frame of the window frame 1 with a fixed axis and supported by a shaft seat. The upper end of the drive screw 5 is fixedly mounted to the drive output shaft end of the reducer. Both sides of the movable window seat 3 are fixedly mounted with transmission screw seats. The end rod of the drive screw 5 is threaded into the screw hole in the middle of the transmission screw seat. The lifting and sliding drive of the movable window seat 3 can be realized through the synchronous operation of the drive screws 5 on both sides. In order to facilitate the lifting and lowering drive control of the window, an operation panel 14 is provided on the rear frame side of the window frame 1.

[0028] The edge-fitting and flip-plate pressing airtight protective structure seals the inner edge seams of the movable window seat 3 through the elastic fit of the sealing edge seat 6. Specifically, the sealing mechanism is used to seal the seams of the movable window seat 3. The sealing mechanism includes the sealing edge seat 6, the flip-plate 7, the spring 8, the telescopic top column 9, and the support shaft column 10. The sealing edge seat 6 is used for sealing and protecting the rear edge of the movable window seat 3, as shown in the attached diagram. Figure 2 As shown, two sets of sealing edge seats 6 are symmetrically fixedly installed on the upper and lower rear sides of the movable window seat 3, as per the attached diagram. Figure 2 As shown, in order to achieve edge sealing protection, a sealing protrusion is provided on the rear side of the sealing edge seat 6. After closing, the sealing protrusion can achieve edge sealing protection by fitting with the frame seat 1 and the frame of the support beam seat.

[0029] The flip-up edge plate 7 is a rigid plate base. It is used for sealing and protecting the outer edge of the movable window base 3. The flip-up edge plate 7 is supported by the support shaft column 10, and in conjunction with the spring 8 and telescopic top column 9, it is pushed and flipped onto the inner side of the frame groove on the upper part of the window frame base 1. Specifically, see attached... Figure 3As shown, the support column 10 is movably inserted and installed inside the shaft hole in the middle of the flip side plate 7. The flip side plate 7 is fixedly rotated and installed inside the frame groove on the upper part of the window frame base 1 by the support column 10. The telescopic top column 9 is used for elastic support of the flip side plate 7. There are multiple telescopic top columns 9. Several telescopic top columns 9 are evenly distributed in an equidistant manner on the upper frame side of the window frame base 1. The telescopic top column 9 is slidably inserted and installed inside the insertion hole in the upper frame part of the window frame base 1 by the spring 8. The end of the telescopic top column 9 is ball-shaped. After installation, the lower end of the telescopic top column 9 slides and pushes against the side plate part of the flip side plate 7. The flip side plate 7 is rotated and installed in the outer groove of the window frame base 1 by the fixed axis rotation support of the support column 10 and the elastic push of the telescopic top column 9. After the movable window base 3 is closed, the flip side plate 7 can be rotated outward by the upward lifting of the window.

[0030] To achieve a closed seam, see attached Figure 3 As shown, elastic sealing strips 11 and inner sealing sheets 12 are respectively provided on the front and rear sides of the flip-up edge plate 7. The elastic sealing strips 11 and inner sealing sheets 12 are fixedly installed on the front and rear sides of the flip-up edge plate 7 in an alternating manner. After the window is closed, the elastic sealing strips 11 and inner sealing sheets 12 are tightly fitted and connected to the edges of the window frame base 1 and the movable window base 3, respectively. By utilizing the flip-up pushing force on both sides of the flip-up edge plate 7, the elastic sealing strips 11 and inner sealing sheets 12, which are arranged in an alternating manner on the front and rear sides of the flip-up edge plate 7, can achieve a tight fit and seal on both the inner and outer sides of the joint. The active pushing and fitting can effectively improve the contact tightness of the sealing side. Compared with the traditional edge strip sealing structure, it has better airtight protection. In order to achieve temporary sealing protection on the outer groove frame side of the window frame base 1 after opening, as shown in the attached... Figure 4 As shown, an outer sealing sheet 13 is fixedly installed on the lower front side of the flip-up side plate 7. After the window is opened, the outer sealing sheet 13 is fitted and supported by the inclined surface of the outer frame side of the window frame base 1.

[0031] Working principle or structural principle: When the window is opened, upon receiving the opening command, two sets of lifting drive motors 4 drive two sets of drive screws 5 to work synchronously, causing the movable window seat 3 to move downwards at a uniform speed to open. During the opening process, as the upper part of the movable window seat 3 moves downwards, the flipping side plate 7, which has lost its upward support, flips clockwise under the push of the telescopic top column 9. When it reaches the flipping stop position, as shown in the attached figure... Figure 4 As shown, the outer sealing piece 13 of the outer edge of the flip-up edge plate 7 is in contact with the inclined surface of the outer side of the window frame 1 to achieve temporary sealing of the gap on the outer side of the window frame 1. When the movable window 3 is fully opened, the edge of the sealing edge 6 at the top rear of the movable window 3 is in contact with the groove of the middle support beam of the window frame 1 to achieve sealing and protection of the moving edge of the movable window 3.

[0032] When the window is opened, the movable window seat 3 is driven to move upwards at a constant speed to close via two sets of lifting drive motors 4. During the closing process, the upward movement of the movable window seat 3 contacts the end plate of the flip-up side plate 7, and the upward lifting causes the flip-up side plate 7 to rotate counterclockwise axially. When it reaches the flip-up stop position, it is as shown in the attached figure. Figure 3 As shown, under the pressure of the flip-up edge plate 7, the inner sealing sheet 12 and the elastic sealing strip 11 on the inner and outer edges of the flip-up edge plate 7 are in close contact with the edge of the movable window seat 3 and the edge of the window frame seat 1, respectively. The contact tightness of the sealing side can be effectively improved by the active pushing and pressing. Compared with the traditional edge strip sealing structure, it has better airtight protection and can effectively prevent water seepage and air leakage in windy and rainy weather. At the same time, the rear of the movable window seat 3 is sealed by two sets of sealing edge seats 6 to achieve closed and sealed protection of the window.

[0033] In summary, this lift window adopts an airtight protective structure with edge-mounted fitting and flip-plate pressing. The joint on the inner edge of the movable window seat 3 is sealed and protected by the elastic fitting of the sealing edge seat 6. A flip-plate 7 is provided on the outer edge joint side of the movable window seat 3. The flip-plate 7 is installed in the outer groove of the window frame seat 1 by the fixed axis rotation support of the support column 10 and the elastic push of the telescopic top column 9. After the movable window seat 3 is closed, the flip-plate 7 can be flipped outward by the upward lifting of the window body. The flip-plate 7 is tightly fitted and sealed on both sides of the joint by the flip-plate 7 and the elastic sealing strip 11 and inner sealing sheet 12 arranged in an alternating pattern on the front and rear sides of the flip-plate 7. The active pushing and fitting can effectively improve the contact tightness of the sealing side, and has better airtight protection than the traditional edge strip sealing structure.
