Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and particularly to an anti-rebound structure applicable to electric lifting windows. Background Art

[0002] With the development of building intelligence, electric lifting windows have been widely used in modern buildings such as office buildings, shopping malls, high-end residences, etc. due to their advantages of convenient operation and space saving. People's requirements for window use are not only limited to lighting and ventilation, but also pay more attention to safety and reliability, which puts higher requirements on the performance of electric lifting windows; When an electric lifting window is lifted or lowered, it is likely to violently impact the side wall of the window frame and rebound due to too fast lifting or lowering speed. Generally, existing devices basically install springs or rubber strips on the side walls of the lifting window or the window frame to absorb energy to prevent rebound. However, due to the relatively slow reaction of the elasticity of the rubber strip or spring when the lifting window has too fast a lifting or lowering speed, when the lifting or lowering speed of the lifting window is too fast, the rubber strip or spring is not only difficult to effectively absorb the impact, but even easily increases the rebound of the lifting window, affecting the safety and lifting efficiency during lifting and lowering. Summary of the Invention

[0003] The purpose of the present invention is to provide an anti-rebound structure applicable to electric lifting windows to solve the problems raised in the above background art.

[0009] Further, the rotating assembly includes a rolling disc rotatably connected to the side of the right-angle plate away from the lifting window, and a fixing rod is fixedly connected to the end of the rolling disc away from the right-angle plate; The biting assembly includes a biting plate rotatably connected to the side of the fixing rod close to the rolling disc. A toothed rack is fixedly connected to the side of the biting plate away from the rolling disc, and a notch is formed on the outer surface of the biting plate.

[0010] Further, the auxiliary assembly includes a serrated ring arranged outside the biting plate. One side of the serrated ring close to the lifting window is fixedly connected to the side wall of the lifting window. The interior of the serrated ring is hollow. A plurality of arc-shaped plates are rotatably connected to the interior of the serrated ring, and a plurality of protruding blocks one are fixedly connected to the side wall of the arc-shaped plate; The auxiliary assembly further includes a plurality of movable plates rotatably connected to the side of the arc-shaped plate away from the biting plate. One end of the movable plate away from the arc-shaped plate is rotatably connected to a turning plate. The turning plate is rotatably connected to the interior of the serrated ring, and a spring shaft is fixedly connected to the side wall of the turning plate.

[0011] Further, the friction mechanism includes a C-shaped frame arranged on the side of the rolling disc away from the lifting window. The friction mechanism further includes: an expansion assembly rotatably arranged on the side wall of the C-shaped frame; a buffer assembly installed inside the expansion assembly.

[0012] Further, the expansion assembly includes two elastic friction plates rotatably connected to the side wall of the C-shaped frame. One end of the two elastic friction plates away from the C-shaped frame is rotatably connected to a hollow block; Among them, the C-shaped frame is slidably connected to the side walls of the two elastic friction plates, and a number of second raised blocks are fixedly connected to the side walls of the C-shaped frame.

[0013] Furthermore, the buffer assembly includes an auxiliary frame fixedly connected to the top of the C-shaped frame.

A rubber strip is fixedly connected to the top of the elastic strip, and the elastic strip is made of an elastic material.

[0014] The present invention has the following beneficial effects: 1. In the present invention, when the lifting window is lifted or lowered rapidly, the lifting window will drive the rolling disc to lift or lower synchronously. When the lifting window is about to reach the limit position, the outer surface of the rolling disc will contact the trapezoidal plate, and the rolling disc will rotate rapidly through the friction with the trapezoidal plate. At this time, the rolling disc will drive the engaging plate to rotate synchronously through the fixed rod. The rotating engaging plate will slide outwards under the action of a large centrifugal force and buckle the first raised block on the inner wall of the arc-shaped plate. The engaging plate will push the arc-shaped plate to rotate, and the arc-shaped plate will push the flip plate to flip outwards through the movable plate. The flip plate will push the spring shaft to slide outwards. The spring shaft sliding outwards will contact the inner wall of the sliding space and form an instantaneous high friction force. Through the instantaneous high friction force between the spring shaft and the inner wall of the sliding space, the lifting speed of the lifting window can be reduced, avoiding the situation that the lifting window rebounds due to too fast lifting speed, improving the safety of the window during use and lifting, and improving the lifting efficiency.

[0015] 2. In the present invention, when the inner wall of the sliding space squeezes the hollow block, the two hollow blocks will squeeze the two ends of the elastic strip through the connecting strip. After the two ends of the elastic strip are squeezed, the middle part of the elastic strip will arch. Through the buffering of the rubber strip on the arched elastic strip, the impact of the lifting window on the window frame during lifting can be reduced, avoiding the situation that the window frame vibrates or deforms.

[0016] 3. In the present invention, when the lifting window is about to reach the limit position, the top of the hollow block will contact the inner wall of the sliding space, and the inner wall of the sliding space will squeeze the hollow block. At the same time, when the engaging plate slides outwards under the action of a large centrifugal force and buckles the arc-shaped plate, the engaging plate will drive the rack to slide outwards synchronously and buckle the second raised block on the inner wall of the C-shaped frame, making the C-shaped frame unable to slide. At this time, the two elastic friction plates will bulge towards the inner wall of the sliding space under the extrusion of the hollow block and the restriction of the C-shaped frame. The two bulging elastic friction plates will be in close contact with the inner wall of the sliding space. Through the close contact, the lifting speed of the lifting window can be further reduced, further avoiding the situation that the lifting window rebounds due to too fast lifting speed.

[0017] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figure 1 - Figure 10 As shown, the present invention is an anti-rebound structure applicable to an electric lifting window, including a window frame 1. A sliding space is provided inside the window frame 1, and further includes: A locking mechanism 2, which is installed inside the sliding space and is used to lock the window when its lifting or lowering speed is too fast; A friction mechanism 3, which is installed on the outer surface of the locking mechanism 2 and is used to contact the inner wall of the sliding space to stop the window; Among them, when the window lifting or lowering speed is too fast, it will be locked by the locking mechanism 2, and the friction mechanism 3 will contact the inner wall of the sliding space to stop the window.

[0023] A lower window 101 is fixedly connected inside the window frame 1, and the following are installed on the window frame 1: A driving assembly 11, which is installed on the top of the lower window 101; A sliding assembly 12, which is slidably arranged inside the sliding space through a fixing member; Among them, the operation of the driving assembly 11 can drive the sliding assembly 12 to lift and lower.

[0024] The locking mechanism 2 includes right-angle plates 211 installed at the four corners on the front side of the sliding assembly 12. The locking mechanism 2 further includes: A rotating assembly 21, which is installed on the side wall of the right-angle plate 211; An engaging assembly 22, which is installed on the side wall of the rotating assembly 21; An auxiliary assembly 23, which is installed on the outer surface of the engaging assembly 22 through a rotating member.

[0025] The driving assembly 11 includes a handrail 111 fixedly connected to the top of the lower window 101. The inside of the handrail 111 is hollow. A driving motor 112 is fixedly connected to the inner wall of the bottom of the handrail 111. The output end of the driving motor 112 is rotatably connected to a bidirectional toothed rod 113, and both the left and right sides of the bidirectional toothed rod 113 rotatably penetrate into the sliding space.

[0026] The sliding assembly 12 includes two racks 121 meshingly connected to the outer surface of the bidirectional rack 113, and a lifting window 122 is fixedly connected between the two racks 121; The fixing member includes four trapezoidal plates 123 fixedly connected to the front inner wall of the sliding space. The four trapezoidal plates 123 are symmetrically arranged in two groups, and the two groups of trapezoidal plates 123 are symmetrically distributed with the lifting window 122 as the center.

[0027] The rotating assembly 21 includes a roller disk 212 rotatably connected to the side of the right-angle plate 211 away from the lifting window 122, and a fixing rod 213 is fixedly connected to the end of the roller disk 212 away from the right-angle plate 211; The engaging assembly 22 includes an engaging plate 221 rotatably connected to the side of the fixing rod 213 close to the roller disk 212. A tooth rack 222 is fixedly connected to the side of the engaging plate 221 away from the roller disk 212. A notch is formed on the outer surface of the engaging plate 221. When the lifting window 122 moves up and down rapidly, the lifting window 122 will drive the roller disk 212 to move up and down synchronously. When the lifting window 122 is about to reach the limit position, the outer surface of the roller disk 212 will contact the trapezoidal plate 123, and the roller disk 212 will rotate rapidly through the friction force with the trapezoidal plate 123. At this time, the roller disk 212 will drive the engaging plate 221 to rotate synchronously through the fixing rod 213.

[0028] The auxiliary assembly 23 includes a serrated ring 231 arranged outside the engaging plate 221. One side of the serrated ring 231 close to the lifting window 122 is fixedly connected to the side wall of the lifting window 122. The inside of the serrated ring 231 is hollow, and a number of arc-shaped plates 232 are rotatably connected inside the serrated ring 231. A number of convex blocks I are fixedly connected to the side wall of the arc-shaped plate 232; The auxiliary assembly 23 further includes a number of movable plates 233 rotatably connected to the side of the arc-shaped plate 232 away from the engaging plate 221.

A spring shaft 235 is fixedly connected to the side wall of the turning plate 234. The rotating engaging plate 221 will slide outwards under the action of large centrifugal force and latch onto the convex block I on the inner wall of the arc-shaped plate 232. The engaging plate 221 will push the arc-shaped plate 232 to rotate. The arc-shaped plate 232 will push the turning plate 234 to turn outwards through the movable plate 233. The turning plate 234 will push the spring shaft 235 to slide outwards. The sliding spring shaft 235 will contact the inner wall of the sliding space and form an instantaneous high friction force.

[0029] The friction mechanism 3 includes a C-shaped frame 311 arranged on the side of the roller disk 212 away from the lifting window 122. The friction mechanism 3 further includes: An expansion assembly 31, and the expansion assembly 31 is rotatably arranged on the side wall of the C-shaped frame 311; The buffer assembly 32 is installed inside the expansion assembly 31. Through the bulging deformation of the expansion assembly 31, the frictional force between the rotating assembly 21 and the inner wall of the sliding space can be further increased.

[0030] The expansion assembly 31 includes two elastic friction plates 312 rotatably connected to the side wall of the C-shaped frame 311. One end of the two elastic friction plates 312 away from the C-shaped frame 311 is rotatably connected to a hollow block 313. Among them, the C-shaped frame 311 is slidably connected to the side walls of the two elastic friction plates 312. A number of second raised blocks are fixedly connected to the side wall of the C-shaped frame 311. 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 engaging plate 221 slides outward under the action of a large centrifugal force and buckles the arc-shaped plate 232, the engaging plate 221 will drive the rack 222 to slide outward synchronously and buckle the second raised blocks on the inner wall of the C-shaped frame 311, making the C-shaped frame 311 unable to slide. At this time, the two elastic friction plates 312 will bulge toward the inner wall of the sliding space under the extrusion of the hollow block 313 and the restriction of the C-shaped frame 311, and the two bulging elastic friction plates 312 will be in close contact with the inner wall of the sliding space.

[0031] The buffer assembly 32 includes an auxiliary frame 321 fixedly connected to the top of the C-shaped frame 311. One end of the auxiliary frame 321 away from the C-shaped frame 311 penetrates through the hollow block 313 and extends to the outside of the hollow block 313. A return spring is fixedly connected to the bottom of the auxiliary frame 321, and the bottom of the return spring is fixedly connected to the side wall of the right-angle plate 211. Among them, an elastic strip 322 is slidably connected between the two auxiliary frames 321. One end of the elastic strip 322 close to the hollow block 313 is rotatably connected to a connecting strip 323. One end of the connecting strip 323 close to the hollow block 313 is rotatably connected to the side wall of 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 an elastic material. When the inner wall of the sliding space squeezes the hollow block 313, the two hollow blocks 313 will squeeze both ends of the elastic strip 322 through the connecting strip 323, and the middle part of the elastic strip 322 will arch up after being squeezed at both ends.

[0032] During use, first install the window frame 1 in the appropriate position, and then start the drive motor 112 when needed. When the drive motor 112 is working, it will drive the bidirectional rack 113 to rotate. When the bidirectional rack 113 rotates, it will drive the lifting window 122 to rise and fall through the rack 121 meshed with it. Subsequently, 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.

[0033] When the lifting window 122 moves up and down rapidly, the lifting window 122 drives the roller disc 212 to move up and down synchronously. When the lifting window 122 is about to reach the limit position, the outer surface of the roller disc 212 contacts the trapezoidal plate 123, and the roller disc 212 rotates rapidly through the frictional force between it and the trapezoidal plate 123. At this time, the roller disc 212 drives the engaging plate 221 to rotate synchronously through the fixed rod 213. The rotating engaging plate 221 slides outward under the action of a large centrifugal force and buckles the first raised block on the inner wall of the arc plate 232. The engaging plate 221 pushes the arc plate 232 to rotate. The arc plate 232 pushes the flip plate 234 to flip outward through the movable plate 233. The flip plate 234 pushes the spring shaft 235 to slide outward. The spring shaft 235 sliding outward contacts the inner wall of the sliding space and forms an instantaneous high frictional force. Through the instantaneous high frictional force between the spring shaft 235 and the inner wall of the sliding space, the lifting speed of the lifting window 122 can be reduced, preventing the lifting window 122 from rebounding due to excessive lifting speed, improving the safety during the use and lifting of the window, and improving the lifting efficiency.

[0034] When the lifting window 122 is about to reach the limit position, the top of the hollow block 313 contacts the inner wall of the sliding space, and the inner wall of the sliding space squeezes the hollow block 313. At the same time, when the engaging plate 221 slides outward under the action of a large centrifugal force and buckles the arc plate 232, the engaging plate 221 drives the rack 222 to slide outward synchronously and buckle the second raised block on the inner wall of the C-shaped frame 311, making the C-shaped frame 311 unable to slide. At this time, the two elastic friction plates 312 bulge toward the inner wall of the sliding space under the extrusion of the hollow block 313 and the restriction of the C-shaped frame 311. The two bulging elastic friction plates 312 are in close contact with the inner wall of the sliding space. Through the close contact, the lifting speed of the lifting window 122 can be further reduced, further preventing the lifting window 122 from rebounding due to excessive lifting speed.

[0035] When the inner wall of the sliding space squeezes the hollow block 313, the two hollow blocks 313 squeeze the two ends of the elastic strip 322 through the connecting bar 323. After the two ends of the elastic strip 322 are squeezed, the middle part of the elastic strip 322 arches. Through the buffering of the rubber strip on the arched elastic strip 322, the impact of the lifting window 122 on the window frame 1 during lifting can be reduced, preventing the window frame 1 from vibrating or deforming.
