Description

Technical Field

[0001] This utility model relates to the field of door and window sliding supports, and in particular to an electric sliding support device for casement windows. Background Technology

[0002] In recent years, with the rapid development of the real estate industry, people have placed increasingly higher demands on the quality of their homes. They not only pay attention to the structure and layout of the house, but also have higher expectations for the functionality and convenience of details such as doors and windows. Casement windows, as a common type of window, are widely used in various residential and commercial buildings due to their good ventilation, sealing performance, and aesthetics.

[0003] A sliding hinge is a linkage-type movable connection device mainly used to connect window sashes and window frames, enabling windows to open and close smoothly. A Chinese utility model patent with publication number CN209482980U discloses a sliding hinge hinge with easy installation. It connects the cantilever to the external window sash by setting a sash mounting plate, and connects the base plate to the external window frame by setting an adjusting block and a fixing block. This eliminates the need for pre-measuring the hinge installation position, making installation simple, sturdy, and durable. The sliding hinge hinge provided by this utility model also has the effect of compensating for base plate installation errors and ensuring tight fit of moving parts.

[0004] However, these traditional casement window sliding support devices mostly rely on manual operation, which has some limitations. For example, in severe weather, such as strong winds or heavy rain, manually closing the window may not be timely, causing rainwater to seep into the room, and there is even a risk that the window sash may be damaged or fall off by strong winds. In addition, traditional sliding support devices may violently collide with the window frame when closing quickly, generating a lot of noise and affecting the user experience. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an electric sliding support device for casement windows, addressing the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric sliding support device for a casement window, comprising a sliding support hinge, the sliding support hinge comprising a base plate assembly and a cantilever assembly, the base plate assembly comprising a base plate and a slider that can slide along the surface of the base plate, the slider being connected to the cantilever assembly and driving the cantilever assembly to open and close, an electric drive mechanism for driving the slider to slide is provided below the base plate, the electric drive mechanism comprising a housing connected to the base plate, a motor and an output shaft disposed within the housing, a drive gear being provided at the output end of the motor, a rack being provided at one end of the slider parallel to the base plate, a driven gear being provided at one end of the output shaft and linked to the drive gear, and a drive gear being provided at the other end and meshing with the rack.

[0007] By adopting the above technical solution, an electric drive mechanism is installed under the base plate. The motor drives the gear transmission system to make the slider slide along the surface of the base plate, thereby driving the cantilever assembly to realize the automatic opening and closing of the window sash. This design not only realizes the automated operation of the window and improves the convenience of use, but also enhances safety, especially in inclement weather conditions. It can be combined with rain sensors or remote control to automatically close the window. At the same time, the motor can also control the closing speed to reduce noise and collision between the window sash and the window frame, extending the service life of the window. In addition, the device can be integrated with smart home systems to improve the level of home intelligence. It also has good adaptability and ease of installation, can adapt to window sashes of different weights and sizes, and can quickly replace traditional manual sliding support devices, improving installation efficiency.

[0008] The aforementioned electric sliding support device for a casement window can be further configured such that: a limiting groove is formed on the surface of the base plate, and the slider passes through the limiting groove and connects to the rack.

[0009] By adopting the above technical solution, by opening a limiting groove on the surface of the base plate and connecting the slider through the limiting groove to the rack, the slider can achieve stable and precise sliding on the surface of the base plate. This design not only improves the stability and reliability of the entire electric sliding support device and ensures the accurate opening and closing of the window sash, but also enhances the overall strength of the structure, enabling the device to withstand greater loads and be suitable for heavier window sashes. At the same time, it limits the stroke range of the slider, so that the two ends of the limiting groove represent the closed state and the maximum open state of the sliding support, respectively.

[0010] The aforementioned electric sliding support device for a casement window can be further configured such that: each side of the base plate is provided with parallel guide rails, and the guide rails and the base plate form a groove that restricts the axial disengagement of the slider.

[0011] The above technical solution features parallel guide rails on both sides of the base plate. These guide rails, together with the base plate, form a sliding groove. Their function is to restrict the slider's axial movement, ensuring that the slider can only slide along the designed path. The guide rail design provides additional support and guidance, making the slider smoother during sliding, reducing the possibility of deviation and wobbling, and enhancing the stability and safety of the entire electric sliding support device. Furthermore, the cooperation between the guide rails and the sliding groove helps improve the accuracy of the slider's movement, ensuring proper meshing between the rack and pinion, thereby achieving precise control of the window sash opening and closing. This structural design simplifies the assembly and maintenance process of the device, while extending its service life and improving its durability and reliability.

[0012] The above-mentioned electric sliding support device for casement windows can be further configured such that: the slider has guide surfaces on both sides that are adapted to the thickness of the sliding groove, and a hinge seat that is hinged to the cantilever assembly is provided between the guide surfaces, wherein the thickness of the hinge seat is greater than the guide surface.

[0013] Using the above technical solution, the guide surfaces on both sides of the slider are matched with the thickness of the slide groove to ensure the stability and accuracy of the slider during the sliding process. A hinge seat with a thickness exceeding that of the guide surfaces is installed between the guide surfaces. This hinge seat is connected to the cantilever assembly, allowing the cantilever assembly to perform hinged movement. This design enhances the strength and support of the structure, enabling the cantilever assembly to withstand greater torque. At the same time, the concave-convex contact surface design ensures the stable sliding limit of the slider and the base plate. The hinge seat design allows the window sash to rotate smoothly when opening and closing, improving the operational flexibility and durability of the entire electric sliding support device.

[0014] The aforementioned electric sliding support device for a casement window can be further configured such that: one end of the base plate corresponding to the rack is provided with a guide flange plate that abuts against the rack.

[0015] By adopting the above technical solution, a guide flange is provided at one end of the base plate corresponding to the rack, which abuts against the rack to enhance the fixing and guiding effect of the rack on the base plate, prevent the rack from shifting or falling off when subjected to external force, ensure the correct meshing between the rack and the drive gear, and thus ensure the stable sliding of the slider along the rack.

[0016] The aforementioned electric sliding support device for a casement window can be further configured such that: a transmission gear set is provided between the driving gear and the driven gear, and the gear ratio between the driving gear and the driven gear is greater than 1.

[0017] By adopting the above technical solution, the gear ratio between the driving gear and the driven gear is greater than 1, which amplifies and precisely controls the output power of the motor. This results in the driven gear rotating at a lower speed than the driving gear, providing greater output torque. This more effectively drives the slider to move along the rack, achieving smooth opening and closing of the window sash. It can maintain stable operation even when facing large loads or resistance. At the same time, the multi-stage gear transmission system can distribute the load, reduce the wear of individual gears, and improve the durability and reliability of the entire transmission system. In addition, the precise setting of the gear ratio can also achieve fine adjustment of the opening and closing speed of the window sash to adapt to different usage needs and environmental conditions, enhancing the user experience.

[0018] The aforementioned electric sliding support device for a casement window can be further configured such that: the transmission gear set includes a first transmission shaft, a second transmission shaft, a third transmission shaft, a fourth transmission shaft, a fifth transmission shaft, a sixth transmission shaft, a seventh transmission shaft, and an eighth transmission shaft arranged sequentially along the direction from the motor to the output shaft; the first transmission shaft is provided with a first transmission large gear and a first transmission small gear meshing with the drive gear; the second transmission shaft is provided with a second transmission large gear and a second transmission small gear meshing with the first transmission small gear; and the third transmission shaft is provided with a third transmission large gear and a third transmission small gear meshing with the second transmission small gear. The transmission shaft has a driving pinion, a fourth transmission gear and a fourth transmission pinion meshing with the third transmission pinion, a fifth transmission gear and a fifth transmission pinion meshing with the fourth transmission pinion, a sixth transmission gear and a sixth transmission pinion meshing with the fifth transmission pinion, a seventh transmission gear and a seventh transmission pinion meshing with the sixth transmission pinion, and an eighth transmission gear with an eighth transmission gear meshing with the seventh transmission pinion and an eighth transmission pinion meshing with the driven gear.

[0019] By adopting the above technical solution, eight transmission shafts are sequentially arranged in the direction from the motor to the output shaft, and each transmission shaft is equipped with meshing gears of different sizes. This achieves the step-by-step transmission and amplification of the motor's output power. This multi-stage gear transmission system not only increases the output torque, enabling the device to easily cope with heavy loads, but also makes the operation smoother through step-by-step deceleration. At the same time, it achieves precise control over the opening and closing speed and position of the window sash, enhancing the user experience. In addition, the multi-stage gear transmission system helps to distribute the load, reduce the wear of individual gears, and improve the durability and reliability of the entire transmission system, thus significantly improving the performance and service life of the entire electric sliding support device.

[0020] The aforementioned electric sliding support device for a casement window can be further configured such that: the electric drive mechanism also includes a control board, the control board is equipped with a wireless receiver, and the control board is electrically connected to the motor.

[0021] Using the above technical solution, the electric drive mechanism integrates a control board and a wireless receiver. The control board is electrically connected to the motor, allowing remote control of the motor's operation via wireless signals, thus automating the window opening and closing process. This design improves ease of operation, allowing users to control the window remotely or through a smart home system without manual operation. Furthermore, the wireless control method simplifies the installation process, eliminating the need for complex wiring, making the entire system installation more flexible and economical, and also facilitating future maintenance and upgrades.

[0022] The aforementioned electric sliding support device for a casement window can be further configured as follows: the cantilever assembly includes a window sash mounting plate, a long support cantilever, a first short support cantilever, and a second short support cantilever; the base plate assembly further includes a fixing block fixedly connected to the base plate; one end of the first short support cantilever is hinged to the end of the window sash mounting plate, and the other end is hinged to the fixing block; one end of the second short support cantilever is hinged to the first hinge shaft of the long support cantilever, and the other end is hinged to the fixing block; one end of the long support cantilever is hinged to a slider, and the other end is hinged to the second hinge shaft of the window sash mounting plate; the first hinge shaft is located in the middle of the long support cantilever, and the second hinge shaft is located in the middle of the window sash mounting plate.

[0023] Using the above technical solution, the cantilever assembly consists of a window sash mounting plate, a long support cantilever, a first short support cantilever, and a second short support cantilever. It connects to the fixing block and the base plate in the base plate assembly, forming a stable support structure. The two ends of the first short support cantilever are hinged to the window sash mounting plate and the fixing block, respectively. The second short support cantilever connects the long support cantilever and the fixing block. One end of the long support cantilever is hinged to the slider, and the other end is hinged to the window sash mounting plate. The first hinge axis on the long support cantilever is located in the middle, and the second hinge axis on the window sash mounting plate is also located in the middle position. This design allows the cantilever assembly to flexibly transmit the force generated by the slider movement, achieving smooth opening and closing of the window sash. It also ensures the stability of the window sash in different positions, enhances the strength and reliability of the entire window support structure, and makes the installation and maintenance of the window sash more convenient.

[0024] The aforementioned electric sliding support device for a casement window can be further configured such that the fixing block is fixedly installed on the base plate by a number of riveting components.

[0025] Using the above technical solution, the fixing block is securely mounted on the base plate using several riveted components. This fixing method not only ensures a firm connection between the fixing block and the base plate, providing sufficient support and stability, but also simplifies the installation process by eliminating the need for complex mechanical fasteners or welding, facilitating quick assembly and disassembly. Furthermore, the riveted connection offers excellent vibration and impact resistance, adapting to window use in various environmental conditions and reducing the risk of window sash wobbling or detachment due to unstable fixing. This improves the durability and reliability of the entire electric sliding support device, ensuring long-term stable operation of the window.

The first hinge shaft 221 is located in the middle of the long support cantilever 22, and the second hinge shaft 221 is located in the middle of the window sash mounting plate 21. Both the long support cantilever 22 and the window sash mounting plate 21 can rotate around their respective midpoint hinge shafts, thereby ensuring the balance and stability of the window sash during opening and closing. The midpoint hinge helps to evenly distribute the weight and force of the window sash, reducing the torsional and bending pressure on the cantilever assembly 2.

[0035] like Figures 1-6As shown, an electric drive mechanism for driving the slider 12 to slide is provided below the base plate 11. The electric drive mechanism includes a housing 3 connected to the base plate 11, a motor 31 and an output shaft 32 disposed inside the housing 3. The output end of the motor 31 is provided with a drive gear 311. One end of the slider 12 is provided with a rack 121 arranged parallel to the base plate 11. One end of the output shaft 32 is provided with a driven gear 321 that is linked to the drive gear 311, and the other end is provided with a drive gear 322 that meshes with the rack 121. A limit groove 111 is formed on the surface of the base plate 11. One end of the slider 12 passes through the limit groove 111 and is connected to the rack 121 through a mounting post 122. Parallel... The guide rail 112 is provided, and the guide rail 112 and the base plate 1 form a groove 113 that restricts the axial disengagement of the slider 12. The slider 12 has guide surfaces 123 on both sides that are adapted to the thickness of the groove 113. A hinge seat 124 is provided between the guide surfaces 123 to be hinged to the long support cantilever 22. The thickness of the hinge seat 124 is greater than that of the guide surface 123, so that the surface of the hinge seat 124 is higher than the groove 113, which facilitates the rotation and opening and closing of the long support cantilever 22 without interfering with the base plate 11. The base plate 11 has a guide flange plate 110 at one end corresponding to the rack 12, which abuts against the rack 12. A transmission gear set 4 is provided between the driving gear 311 and the driven gear 321.

[0036] like Figures 2-5 As shown, the transmission gear set 4 includes a first transmission shaft 41, a second transmission shaft 42, a third transmission shaft 43, a fourth transmission shaft 44, a fifth transmission shaft 45, a sixth transmission shaft 46, a seventh transmission shaft 47, and an eighth transmission shaft 48 arranged sequentially along the direction from the motor 31 to the output shaft 32. The first transmission shaft 41 is equipped with a first transmission large gear 411 and a first transmission small gear 412 that mesh with the drive gear 311. The second transmission shaft 42 is equipped with a second transmission large gear 421 and a second transmission small gear 422 that mesh with the first transmission small gear 412. The third transmission shaft 43 is equipped with a third transmission large gear 431 and a third transmission small gear 432 that mesh with the second transmission small gear 422.

The sixth drive shaft 46 has a sixth drive gear 461 and a sixth drive gear 462 that mesh with the fifth drive pinion 452. The seventh drive shaft 47 has a seventh drive gear 471 and a seventh drive pinion 472 that mesh with the sixth drive pinion 462. The eighth drive shaft 48 has an eighth drive gear 481 that meshes with the seventh drive pinion 472 and an eighth drive pinion 482 that meshes with the driven gear 321.

[0037] like Figures 1-3As shown, the electric drive mechanism also includes a control board 5, which is equipped with a wireless receiver 51. The control board 5 is electrically connected to the motor 31, enabling the electric sliding support device to wirelessly connect with a mobile APP. Users can remotely control the window sash opening and closing at home. At the same time, the motor 31 is preferably a non-locking motor. When the window sash is manually opened and closed, the motor 31 will rotate along with it to avoid causing a load when manually opening and closing.

[0038] like Figure 7 The diagram shows the electric sliding support device mounted on a casement window. The base plate assembly 1 of the electric sliding device is installed on the window frame 6, and the cantilever assembly 2 is connected to the window sash 61. A wireless receiver 51 and a rain sensor can also be installed on the casement window. When the window is open for ventilation and it rains, the rain sensor detects the rain and sends a signal to the control board 5 to close the window via the wireless receiver 51. Simultaneously, it sends a message to the user app. The motor 31 drives the output shaft 32 to rotate via the transmission gear set 4, causing the drive gear 322 to rotate and drive the gear... The end of the rack 121 away from the fixed block 13 moves, causing the slider 12 to rotate to the end of the limiting groove 111, thereby driving the window sash 61 on the window sash mounting plate 21 to close. However, when remote ventilation is required, the user only needs to send a control command remotely. The wireless receiver 51 sends a window opening signal to the control board 5. The motor 31 will drive the output shaft 32 to rotate through the transmission gear set 4, causing the drive gear 322 to rotate, driving the rack 121 to move toward the end of the fixed block 13, causing the slider 12 to rotate to the beginning of the limiting groove 111, thereby driving the window sash 61 on the window sash mounting plate 21 to open.
