An anti-rebound structure suitable for electric lifting windows

Abstract

The present invention relates to the technical field of doors and windows, and discloses an anti-rebound structure suitable for electric lift windows, comprising a window frame, a sliding space defined within the window frame, and a locking mechanism installed within the sliding space for generating instantaneous high friction when the window is raised or lowered too quickly. In the present invention, when the lift window is raised or lowered rapidly, the lift window drives a roller to rise or fall synchronously. When the lift window is about to reach its limit position, the outer surface of the roller contacts a trapezoidal plate, and the roller rapidly rotates due to friction between the roller and the trapezoidal plate. A spring shaft sliding outward contacts the inner wall of the sliding space, generating instantaneous high friction. The instantaneous high friction between the spring shaft and the inner wall of the sliding space reduces the lifting speed of the lift window, preventing the lift window from rebounding due to excessive lifting speed, thereby improving safety during window use and lifting, and increasing lifting efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and in particular to an anti-rebound structure suitable for an electric lifting window. Background Art

[0002] With the development of intelligent buildings, electric windows have been widely used in modern buildings due to their advantages of convenient operation and space saving, such as office buildings, shopping malls, high-end residences, etc. People's requirements for windows are not limited to lighting and ventilation, but also pay more attention to safety and reliability, which puts higher requirements on the performance of electric windows.

[0003] When an electric window is raised or lowered, it is easy for the window to violently impact the side wall of the window frame and rebound due to the high raising or lowering speed. Generally, existing devices basically absorb energy by installing springs or rubber strips on the side wall of the window or window frame to prevent rebound. However, due to the elasticity of the rubber strips or springs, their reaction is relatively slow when the window is raised or lowered too quickly. When the window is raised or lowered too quickly, the rubber strips or springs are not only unable to effectively absorb the impact, but may even increase the rebound of the window, affecting the safety and efficiency of the lifting process.

[0065] The fixing member includes four trapezoidal plates 123 fixedly connected to the inner wall of the front side of the sliding space. The four trapezoidal plates 123 are symmetrically arranged in groups of two, and the two groups of trapezoidal plates 123 are symmetrically distributed with the lifting window 122 as the center.

[0066] The rotating assembly 21 includes a roller 212 rotatably connected to a right-angle plate 211 away from the lifting window 122 , and a fixed rod 213 is fixedly connected to one end of the roller 212 away from the right-angle plate 211 ;

A notch is provided on the outer surface of the bite plate 221. When the lifting window 122 is raised and lowered quickly, the lifting window 122 will drive the roller 212 to rise and fall synchronously. When the lifting window 122 is about to reach the limit position, the outer surface of the roller 212 will contact the trapezoidal plate 123, and the roller 212 will rotate rapidly due to the friction between the trapezoidal plate 123. At this time, the roller 212 will drive the bite plate 221 to rotate synchronously through the fixed rod 213.

[0068] The auxiliary assembly 23 includes a serrated ring 231 disposed on the outside of the bite plate 221. The side of the serrated ring 231 near the lift window 122 is fixedly connected to the side wall of the lift window 122. The interior of the serrated ring 231 is hollow.

[0069] The auxiliary component 23 also includes several movable plates 233 rotatably connected to the side of the arc plate 232 away from the bite plate 221. The end of the movable plate 233 away from the arc plate 232 is rotatably connected to a flip plate 234. The flip plate 234 is rotatably connected to the inside of the serrated ring 231. The side wall of the flip plate 234 is fixedly connected to a spring shaft 235. The rotating bite plate 221 will slide outward under the action of large centrifugal force and buckle the raised block 1 on the inner wall of the arc plate 232. The bite plate 221 will push the arc plate 232 to rotate. The arc plate 232 will push the flip plate 234 to flip outward through the movable plate 233. The flip plate 234 will push the spring shaft 235 to slide outward. The outward sliding spring shaft 235 will contact the inner wall of the sliding space and form an instantaneous high friction force.

[0070] The friction mechanism 3 includes a C-shaped frame 311 disposed on the side of the roller 212 away from the lifting window 122, and the friction mechanism 3 also includes:

[0071] An expansion assembly 31 is rotatably mounted on a side wall of a C-shaped frame 311;

[0072] The buffer component 32 is installed inside the expansion component 31. The bulging deformation of the expansion component 31 can further increase the friction between the rotating component 21 and the inner wall of the sliding space.

[0073] The expansion assembly 31 includes two elastic friction plates 312 rotatably connected to the side walls of the C-shaped frame 311 , and one end of the two elastic friction plates 312 away from the C-shaped frame 311 is rotatably connected to a hollow block 313;

[0074] The two elastic friction plates 312 will bulge toward the inner wall of the sliding space under the squeezing of the hollow blocks 313 and the restriction of the C-shaped frame 311, and the two raised elastic friction plates 312 will be in close contact with the inner wall of the sliding space.

[0075] The buffer assembly 32 includes an auxiliary frame 321 fixedly connected to the top of the C-shaped frame 311. The end of the auxiliary frame 321 away from the C-shaped frame 311 passes through the hollow block 313 and extends to the outside of the hollow block 313. The bottom of the auxiliary frame 321 is fixedly connected to a return spring, and the bottom of the return spring is fixedly connected to the side wall of the right-angle plate 211.

[0076] Among them, an elastic strip 322 is slidably connected between the two auxiliary frames 321, and the elastic strip 322 is rotatably connected to the connecting strip 323 at one end close to the hollow block 313. The connecting strip 323 is rotatably connected to the side wall of the hollow block 313 at one end close to the hollow block 313. A rubber strip is fixedly connected to the top of the elastic strip 322. The elastic strip 322 is made of elastic material. When the inner wall of the sliding space squeezes the hollow block 313, the two hollow blocks 313 will squeeze the two ends of the elastic strip 322 through the connecting strip 323. After the two ends of the elastic strip 322 are squeezed, the middle part of the elastic strip 322 will arch.

[0077] When in use, first install the window frame 1 to the appropriate position, and then start the drive motor 112 when needed. The drive motor 112 will drive the two-way gear rod 113 to rotate when working. When the two-way gear rod 113 rotates, it will drive the lifting window 122 to move up and down through the rack 121 engaged with it. Then, when the lifting window 122 is about to reach the limit position, the inner wall of the sliding space will contact the rubber strip on the elastic strip 322 and achieve the purpose of anti-rebound under the buffering of the rubber strip.

[0078] When the lifting window 122 is lifted and lowered quickly, the lifting window 122 will drive the roller 212 to lift and lower synchronously. When the lifting window 122 is about to reach the limit position, the outer surface of the roller 212 will contact the trapezoidal plate 123, and the roller 212 will rotate rapidly due to the friction between the roller and the trapezoidal plate 123. At this time, the roller 212 will drive the bite plate 221 to rotate synchronously through the fixing rod 213. The rotating bite plate 221 will slide outward under the action of the large centrifugal force and buckle the protrusion block 1 on the inner wall of the arc plate 232. The bite plate 221 will push When the curved plate 232 rotates, the curved plate 232 will push the flip plate 234 to flip outward through the movable plate 233, and the flip plate 234 will push the spring shaft 235 to slide outward. The outward sliding spring shaft 235 will contact the inner wall of the sliding space and form an instantaneous high friction force. The instantaneous high friction force between the spring shaft 235 and the inner wall of the sliding space can reduce the lifting speed of the lifting window 122, avoiding the lifting window 122 from rebounding due to excessive lifting speed, thereby improving the safety of the window during use and lifting, and improving the lifting efficiency.

[0079] When the lifting window 122 is about to reach the limit position, the top of the hollow block 313 will contact the inner wall of the sliding space, and the inner wall of the sliding space will squeeze the hollow block 313. At the same time, when the bite plate 221 slides outward under the action of the large centrifugal force and buckles the curved plate 232, the bite plate 221 will drive the tooth frame 222 to slide outward synchronously and buckle the raised block 2 on the inner wall of the C-shaped frame 311, so that the C-shaped frame 311 cannot slide. At this time, the two elastic friction plates 312 will bulge toward the inner wall of the sliding space under the squeezing of the hollow block 313 and the restriction of the C-shaped frame 311. The raised two elastic friction plates 312 will be in close contact with the inner wall of the sliding space. The close contact can further reduce the lifting speed of the lifting window 122, and further prevent the lifting window 122 from rebounding due to excessive lifting speed.

[0080] When the inner wall of the sliding space squeezes the hollow block 313, the two hollow blocks 313 will squeeze the two ends of the elastic strip 322 through the connecting strip 323. After the two ends of the elastic strip 322 are squeezed, the middle part of the elastic strip 322 will be arched. The rubber strip on the arched elastic strip 322 can cushion the impact of the lifting window 122 on the window frame 1 when it is raised or lowered, thereby avoiding vibration or deformation of the window frame 1.
