Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of doors and windows, and more particularly to a screen-equipped electric lifting window. BACKGROUND

[0002] As a new electric door and window product in recent years, the electric lifting window is favored by users because it has the characteristics of large opening and high transparency, and is often used in the scene of sealing a balcony or a window, which is easily exposed to direct sunlight at noon, resulting in a too dazzling indoor environment. At present, an external electric screen is used to block the light.

[0003] However, this scheme still has many problems in actual use, for example: the existing electric lifting window needs to reserve an additional space position for the electric screen, resulting in a larger cavity thickness, and the window occupies more space, which is very unreasonable. For details, please refer to the accompanying drawings Figure 5 and the Chinese utility model patent with the publication number CN218780282U - a screen fan combined lifting window, which discloses the technical content: the electric screen fan is fixed on the outer frame through the screen fan frame, and the side close to the outdoor is also connected with the window sash of the movable window through the movable groove. This setting method occupies too much space for the electric screen. On the other hand, the electric screen and the movable window are two independent products connected by a spliced structure, and the maintenance methods of the two are different. When repairing, the electric screen needs to be disassembled from the movable window using tools, resulting in too much maintenance workload.

[0004] Therefore, the connection between the electric lifting window and the screen window in the prior art has the problems of large space occupation and inconvenient maintenance. UTILITY MODEL CONTENT

[0005] The purpose of the present application is to provide a screen-equipped electric lifting window with the advantages of compact structure, space saving, convenient maintenance and maintenance.

[0007] An upper rail is provided with a screen installation cavity, a reel base is arranged in the screen installation cavity, and a detachable screen is installed on the reel base. One side of the screen installation cavity is provided with a detachable reel repair cover.

[0008] Further comprising guide grooves arranged on both sides of the electric lifting window frame, the guide grooves are connected with both sides of the screen, and are used for guiding the lifting of the screen. The edges of both sides of the screen are provided with counterweight strips, and the counterweight strips are in sliding cooperation with the guide grooves.

[0009] The application provides a screen motorized lift window, which is characterized in that a screen winding installation cavity is arranged in an upper rail of a motorized lift window frame body, the screen winding is integrated into the motorized lift window structure, and space occupation is effectively reduced. The design of a winding shaft base and a detachable winding shaft repair cover facilitates the installation and maintenance of the screen. The design of a guide groove and a counterweight strip ensures the stability and smoothness of the screen winding during lifting. The guide groove is connected to both sides of the screen winding, guides the lifting movement of the screen winding, and prevents the screen winding from deviating or deforming during lifting. The counterweight strip not only increases the weight of the screen winding, so that the screen winding is smoother during lowering, but also further ensures the stability of the screen winding movement through sliding cooperation with the guide groove. This design ingeniously integrates the screen function into the interior of the motorized lift window, eliminates the screen fan structure, and solves the problems of large space occupation and inconvenient maintenance caused by the separation of the motorized lift window and the screen in the traditional scheme.

[0010] Further, the upper rail is further provided with the motorized lift window, and the motorized lift window is arranged at the side of the screen winding installation cavity and is in sliding connection with the winding shaft base.

[0011] The application provides a screen motorized lift window, which is characterized in that a screen motorized lift window is arranged in an upper rail, and the screen motorized lift window is arranged at the side of a screen winding installation cavity, so that the screen motorized lift window and the screen winding installation structure are arranged in a compact manner. The sliding connection design between the screen motorized lift window and the winding shaft base ensures smooth operation of the screen motorized lift window and maintains coordinated work with the screen winding installation structure.

[0012] Further, a first sealing structure is arranged on a first contact surface of the winding shaft base in contact with the screen motorized lift window, and the first sealing structure is in contact with the side of the screen motorized lift window close to the indoor side, so as to reduce noise generated during lifting of the screen motorized lift window and prevent rainwater from entering the indoor side.

[0013] In the application, the first sealing structure is arranged on the first contact surface of the winding shaft base in contact with the screen motorized lift window and is in contact with the side of the screen motorized lift window close to the indoor side. On one hand, the first sealing structure can reduce noise generated during lifting of the screen motorized lift window. When the screen motorized lift window is lifted, the first sealing structure can reduce friction and collision between the winding shaft base and the screen motorized lift window, so that noise is effectively reduced. On the other hand, the first sealing structure can also prevent rainwater from entering the indoor side. Since the first sealing structure is in contact with the side of the screen motorized lift window close to the indoor side, the first sealing structure can form a sealing barrier between the screen motorized lift window and the winding shaft base, so that rainwater is effectively prevented from entering the indoor side from this position.

[0014] Further, a second sealing structure is arranged on a second contact surface of the winding shaft base in contact with the screen motorized lift window, and the second sealing structure is in contact with the top of the screen motorized lift window, so as to prevent the screen motorized lift window from colliding with the winding shaft base during lifting.

[0015] The second sealing structure is arranged on the second contact surface of the reel base in contact with the electric lifting window, which can play a buffering role and effectively prevent the electric lifting window from directly colliding with the reel base during lifting.

[0016] Further, the electric lifting window frame body further comprises a mullion, which is arranged on the side of the electric lifting window close to the indoor side; after the reel yarn is lowered, the counterweight strip is in contact with the upper surface of the mullion.

[0017] Further, the side of the counterweight strip in contact with the mullion is provided with an elastic buffer component to prevent the counterweight strip from impacting the mullion when it is lowered.

[0018] Further, a third sealing structure is arranged between the electric lifting window and the mullion, which is used to prevent rain and noise from the outside from entering the indoor side.

[0019] Further, the side of the reel base in contact with the reel yarn is arranged as an arc-shaped surface, which matches the cylindrical structure surface of the reel yarn when it is wound.

[0020] Further, the side of the reel repair cover in contact with the reel yarn is arranged as an arc-shaped surface, which matches the cylindrical structure surface of the reel yarn when it is wound; there is a gap between the end of the reel base and the end of the reel repair cover for releasing the reel yarn.

[0021] Further, the reel repair cover is hinged on one side of the reel yarn installation cavity.

[0022] Beneficial effects: The electric lifting window with a screen proposed in the application integrates the reel yarn into the electric lifting window structure by arranging a reel yarn installation cavity in the upper rail of the electric lifting window frame body, effectively reducing the space occupation. The design of the reel base and the detachable reel repair cover facilitates the installation and maintenance of the screen window. The design of the guide groove and the counterweight strip ensures the stability and smoothness of the reel yarn during lifting. The guide groove is connected to both sides of the reel yarn to guide the lifting movement of the reel yarn and prevent the reel yarn from deviating or deforming during lifting. The counterweight strip not only increases the weight of the reel yarn, making it more smooth when it is lowered, but also further ensures the stability of the reel yarn movement through sliding cooperation with the guide groove. This design ingeniously integrates the screen function into the electric lifting window, eliminates the screen fan structure, and solves the problems of large space occupation and inconvenient maintenance caused by the separation of the electric lifting window and the screen in the traditional scheme.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and indicated in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] At present, the existing motorized lift window needs to reserve additional installation space for the motorized winding, resulting in an increase in the overall structure thickness and the occupation of more space; and the motorized winding and the motorized lift window are independent components, which need to be handled separately during maintenance, increasing the maintenance workload. These problems seriously affect the practicability and user experience of the motorized lift window. In order to solve this problem, the present application provides a motorized screen lift window.

[0032] Please refer to Figures 1 to 5 A motorized screen lift window includes a motorized lift window frame body 1, which at least includes:

[0033] The upper rail 2 is provided with a yarn winding installation cavity 31, and the yarn winding installation cavity 31 is provided with a reel base 4, and the reel base 4 is provided with a detachable yarn winding 6; one side of the yarn winding installation cavity 31 is provided with a detachable reel repair cover 7.

[0034] Further comprising guide grooves 21 arranged on both sides of the electric lifting window frame body 1, the guide grooves 21 are connected with both sides of the yarn winding 6, and are used for guiding the yarn winding 6 to lift; the edges of both sides of the yarn winding 6 are provided with counterweight strips 61, and the counterweight strips 61 are in sliding fit with the guide grooves 21.

[0035] The yarn winding installation cavity 31 is arranged in the upper rail 2 of the electric lifting window frame body 1, which does not increase the overall thickness and effectively utilizes the original space. In order to facilitate installation and maintenance, the reel base 4 is arranged in the yarn winding installation cavity 31, and the reel repair cover 7 is designed on one side. Specifically, one end of the reel repair cover 7 is hinged to one side of the yarn winding installation cavity 31, when the yarn winding 6 needs to be repaired, the reel repair cover 7 is turned around the hinge end, and the yarn winding 6 is lifted out of the yarn winding installation cavity 31, which not only realizes the integration of the screen window, but also greatly improves the maintenance convenience.

[0036] Please refer to Figure 4 In order to ensure the stable operation of the yarn winding 6, the guide grooves 21 are arranged on both sides of the electric lifting window frame body 1, and are connected with both sides of the yarn winding 6, and are used for guiding the yarn winding 6 to lift. At the same time, in order to increase the stability of the yarn winding 6 and the smoothness when descending, the counterweight strips 61 are arranged at the edges of both sides of the yarn winding 6, and are in sliding fit with the guide grooves 21. The guide grooves 21 are arranged on the window frames 3 on both sides of the electric lifting window frame body 1, the window frames 3 are connected with both sides of the yarn winding 6, and the yarn winding 6 is lifted along the guide grooves, so that the yarn winding 6 can cover the entire window frame area of the electric lifting window 5 when the electric lifting window 5 is opened, and block the mosquitoes from flying into the room. Preferably, in order to make the yarn winding 6 better lift along the guide grooves 21, the yarn winding end covers 62 are arranged at both ends of the yarn winding 6, and the yarn winding end covers 62 are in fit with the guide grooves 21, and can better slide.

[0037] The yarn winding installation cavity 31 is arranged in the upper rail 2 to cancel the screen fan structure in the prior art, and the problems of space occupation and maintenance convenience are solved. The yarn winding 6 is integrated in the electric lifting window frame body 1, and does not need additional installation space. The detachable reel repair cover 7 design makes maintenance and replacement simple and fast, and greatly reduces the maintenance time and cost.

[0038] In specific implementation, the winding installation cavity 31 can be in a cylindrical shape to match the shape of the winding 6 when it is being wound. The winding shaft base 4 can be made of wear-resistant materials such as high-strength engineering plastics or light metal alloys to ensure stability during long-term use. The guide groove 21 can be made of materials with low friction coefficients such as polytetrafluoroethylene (PTFE) coated metals or high-molecular materials to reduce resistance when the winding 6 is being raised and lowered. The counterweight strip 61 can be made of metal materials such as aluminum alloys or stainless steel to ensure weight without adding too much thickness. The sliding fit between the counterweight strip 61 and the guide groove 21 can be designed with rollers to further reduce friction and improve smoothness of operation.

[0039] Therefore, the technical scheme of the present application effectively solves the problems of additional space occupation and inconvenient maintenance of traditional external electric winding 6 by integrating the winding installation cavity 31 into the upper rail 2 of the electric lifting window 5. This not only improves space utilization but also makes the product appearance more simple and elegant.

[0040] Further, the electric lifting window 5 is arranged in the upper rail 2 and is located at the side of the winding installation cavity 31 and is in sliding connection with the winding shaft base 4.

[0041] Among them, by arranging the electric lifting window 5 in the upper rail 2 and arranging it at the side of the winding installation cavity 31, a compact layout of the electric lifting window 5 and the winding 6 installation structure is realized. The sliding connection design between the electric lifting window 5 and the winding shaft base 4 ensures smooth operation of the electric lifting window 5 and does not interfere with the operation of the winding 6.

[0042] Further, the first contact surface 41 of the winding shaft base 4 in contact with the electric lifting window 5 is provided with a first sealing structure 8, which is in contact with the side of the electric lifting window 5 close to the indoor side, for reducing noise generated when the electric lifting window 5 is raised and lowered and preventing rainwater from entering the indoor side.

[0043] Among them, please refer to Figure 2 , Figure 3 The winding shaft base 4 can be in a "7" shape structure, the side of the winding shaft base 4 parallel to the lifting direction of the electric lifting window 5 is the first contact surface 41, and the first sealing structure 8 is arranged on the first contact surface 41. The first sealing structure 8 can be a sealing wool strip, which can effectively reduce the noise generated when the electric lifting window 5 is raised and lowered. Since the sealing wool strip is arranged on the side of the electric lifting window 5 close to the indoor side, it can form a sealing barrier between the electric lifting window 5 and the winding shaft base 4, effectively blocking rainwater from entering the indoor side from this position, improving the air and water tightness of the electric lifting window with winding.

[0044] The first contact surface 41 is provided with a mounting groove, and the first sealing structure 8 is embedded in the mounting groove and in contact with the electric lifting window 5. The embedded mounting mode can improve the stability and durability of the first sealing structure 8.

[0045] Further, the second contact surface 42 of the reel base 4 in contact with the electric lifting window 5 is provided with a second sealing structure 9, which is in contact with the top of the electric lifting window 5, for preventing the electric lifting window 5 from colliding with the reel base 4 during lifting.

[0046] The reel base 4 has a second contact surface 42 perpendicular to the lifting direction of the electric lifting window 5, and the second contact surface 42 is provided with a second sealing structure 9, which is a buffer rubber strip. Figure 3 When the electric lifting window 5 is closed, the buffer rubber strip can prevent the electric lifting window 5 from colliding with the reel base 4 and reduce noise. In combination with the first sealing structure 8, the buffer rubber strip can also prevent rainwater from entering the room from this position, further improving the water and air tightness of the electric lifting window with screen.

[0047] In specific embodiments, the second sealing structure 9 has a protruding part in contact with the top of the electric lifting window 5. The second sealing structure 9 is fixed on the reel base 4 through a pre-set clamping groove, ensuring stable installation of the sealing strip. The surface of the sealing strip is specially treated to have a low friction coefficient, which can reduce the resistance when in contact with the electric lifting window 5.

[0048] Further, the electric lifting window frame 1 further comprises a mullion 10 arranged on the side of the electric lifting window 5 close to the room, and the counterweight strip 61 is in contact with the upper surface of the mullion 10 after the screen reel 6 is lowered.

[0049] The technical scheme adds a mullion 10 structure to the electric lifting window frame 1 to solve the problem of fixing the screen reel 6 after it is lowered. The mullion 10 is arranged on the side of the electric lifting window 5 close to the room, providing a stable support point for the screen reel 6. When the screen reel 6 is completely lowered, the counterweight strip 61 is in contact with the upper surface of the mullion 10, which not only ensures that the screen reel 6 remains in a tensioned state but also prevents the screen reel 6 from continuing to slide down. Through this design, the screen reel 6 can remain stable during the lowering process, avoiding the possibility of shaking or unevenness when the screen reel 6 is lowered. At the same time, the arrangement of the mullion 10 also provides additional support for the electric lifting window 5, enhancing the stability of the entire window structure. The contact between the counterweight strip 61 and the mullion 10 not only fixes the screen reel 6 but also prevents external wind from affecting the screen reel 6, improving the stability and safety of the entire system.

[0050] The setting position of the mullion 10 can be adjusted according to actual needs. Generally, the mullion 10 can be set at 1 / 2 of the height of the electric lifting window 5, so as to ensure the stability of the descending winding yarn 6 while not excessively affecting the view of the electric lifting window 5. The material of the mullion 10 can be selected from aluminum alloy, stainless steel or high-strength engineering plastic, etc. to ensure sufficient strength and durability.

[0051] The contact mode of the counterweight strip 61 with the mullion 10 can be that a magnetic material is added at the bottom of the counterweight strip 61 to form magnetic force adsorption with the metal material on the mullion 10, thereby improving the reliability of fixation.

[0052] Further, the side of the counterweight strip 61 in contact with the mullion 10 is provided with an elastic buffer component to prevent the counterweight strip 61 from impacting the mullion 10 when descending.

[0053] The elastic buffer component can be in various forms, such as a rubber strip, an elastic sealing strip or a silica gel sealing strip. These materials have good elasticity and sealing performance and can adapt to the possible small gap between the electric lifting window 5 and the mullion 10. The third sealing structure 11 can have different cross-sectional shapes, such as U-shaped, V-shaped or lip-shaped, to better fit the surface of the electric lifting window 5 and the mullion 10. Figure 2 、 Figure 3 The elastic buffer component provided on the side of the counterweight strip 61 in contact with the mullion 10 effectively solves the problem that the counterweight strip 61 may impact the mullion 10 when descending. This design not only reduces noise and improves user comfort, but also prolongs the service life of the electric lifting window 5 and reduces maintenance costs. At the same time, this simple and effective solution does not significantly increase the complexity and cost of the product, and has good practicability and economy.

[0054] In some embodiments of the present application, the elastic buffer component can adopt various materials and structural forms. For example, rubber, silica gel, elastic plastic or other materials with good elasticity and buffering performance can be used. These materials can be made into strips, sheets or other suitable shapes for installation on the side of the counterweight strip 61 in contact with the mullion 10.

[0055] Further, a third sealing structure 11 is arranged between the electric lifting window 5 and the mullion 10, and the third sealing structure 11 is used to prevent rain and noise from the outside from entering the room.

[0056] The third sealing structure 11 arranged between the electric lifting window 5 and the mullion 10 can effectively fill the gap between the electric lifting window 5 and the mullion 10, form a sealed barrier and solve the problem of rain and noise from the outside entering the room.

[0057] The third sealing structure 11 can be implemented in various forms, such as a flexible rubber strip, an elastic sealing strip or a silica gel sealing strip. These materials have good elasticity and sealing performance and can adapt to the possible small gap between the electric lifting window 5 and the mullion 10. The third sealing structure 11 can have different cross-sectional shapes, such as U-shaped, V-shaped or lip-shaped, to better fit the surface of the electric lifting window 5 and the mullion 10.

[0058] In the installed position, the third sealing structure 11 can be fixed on the mullion 10 or the edge of the electric lift window 5. Specifically, a mounting groove can be formed on the mullion 10, and the sealing strip is embedded in the groove; or a recess is designed on the edge of the electric lift window 5, and the sealing strip is fixed in the recess.

[0059] The third sealing structure 11 cooperates with the first sealing structure 8 and the second sealing structure 9 of the electric lift window 5 to provide comprehensive waterproof and noise-proof protection. When the electric lift window 5 is closed, the third sealing structure 11 closely adheres to the mullion 10, while the first sealing structure 8 and the second sealing structure 9 on the upper part ensure the sealing of the top, forming a closed space that effectively blocks the influence of the external environment, improving the water and air tightness of the electric lift window with screen.

[0060] Further, the side of the reel base 4 in contact with the winding screen 6 is designed as an arc surface that matches the surface of the cylindrical structure formed when the winding screen 6 is wound.

[0061] Further, the side of the reel base 4 in contact with the winding screen 6 is designed as an arc surface that matches the surface of the cylindrical structure formed when the winding screen 6 is wound.

[0062] Further, the side of the reel base 4 in contact with the winding screen 6 is designed as an arc surface that matches the surface of the cylindrical structure formed when the winding screen 6 is wound.

[0063] Further, the side of the reel base 4 in contact with the winding screen 6 is designed as an arc surface that matches the surface of the cylindrical structure formed when the winding screen 6 is wound.

[0064] Further, the reel repair cover 7 is hinged on one side of the winding screen mounting cavity 31.

[0065] Wherein the reel repair cover 7 is hinged on one side of the yarn installation cavity 31, the flexible opening and closing of the reel repair cover 7 can be achieved. Through the hinged structure, the reel repair cover 7 can be easily opened and closed without the need for complete disassembly. This design greatly improves the convenience of installation, replacement and maintenance of the yarn 6. When it is necessary to check, repair or replace the yarn 6, only the hinged reel repair cover 7 needs to be opened to easily access the inside of the yarn installation cavity 31. After the operation is completed, the reel repair cover 7 is closed. This design not only simplifies the maintenance process, but also reduces the risk of disassembling parts, improves the safety and efficiency of the overall operation. In addition, the hinged design also ensures the positioning accuracy of the reel repair cover 7. Each time it is closed, the reel repair cover 7 can be accurately returned to its original position, ensuring the sealing of the yarn installation cavity 31 and the stability of the overall structure. This design not only facilitates daily use and maintenance, but also ensures the normal function and performance of the electric lift window 5.
