Description

Technical Field

[0001] This utility model relates to the field of lifting window technology, specifically a glass-embedded lifting window. Background Technology

[0002] With economic development and improved living standards, the demand for smart homes is increasing, and windows, as essential furniture items in residences, are also receiving higher and higher expectations. Currently, enclosed balconies, bedrooms, and offices in residential and commercial buildings typically have casement or sliding windows, which cannot be fully opened in sunny weather, resulting in inadequate ventilation. In recent years, a type of lift-up window has emerged for balcony enclosures and general window use. Its structure mainly consists of an outer lift-up window sash and an inner fixed window sash. Its advantage is that the outer lift-up window sash can be fully opened, providing a larger ventilation area and improving comfort.

[0003] For electric lift windows, a servo motor is usually used to drive a screw mechanism to control the lifting of the window, and a photoelectric sensor is used to detect obstacles and stop the machine. However, a single protection mechanism has the risk of failure. When the sliding window is lowered, the photoelectric switch detects a person's palm and the system can stop the motor. However, if the servo controller fails, the window may still slide down due to gravity and cause crush injury to the person's palm. Therefore, a glass-embedded lift window is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a glass-embedded lifting window to solve the problem mentioned in the background art. For electric lifting windows, a servo motor is usually used to drive a screw mechanism to control the lifting of the window and a photoelectric sensor is used to detect obstacles and stop the machine for protection. However, the single protection mechanism has the risk of failure. When the moving window is lowered, the photoelectric switch detects a person's palm and the system can stop the motor. However, if the servo controller fails or the mechanical jams, the window may still cause the person's palm to be squeezed and injured due to gravity as it slides down.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass-embedded lift window, comprising...

[0006] A window frame, with glass embedded in the front side of the window frame, edge strips snapped onto the four sides of the glass on the window frame, a movable window provided on the inner side of the window frame behind the glass, and protective components provided on the crossbeam of the window frame.

[0007] The protective assembly includes a fixed shaft, a cover plate, and two fixed seats. A groove is provided on the top of the crossbeam of the window frame. The fixed shaft is fixedly connected to the inside of the groove. The cover plate is movably connected to the outside of the fixed shaft. The two fixed seats are fixedly connected to the bottom of the cover plate. One end of a connecting rod is hinged to the outside of the two fixed seats. Two U-shaped grooves are fixedly connected to the bottom of the groove. Both sides of the U-shaped grooves are provided with long through grooves. The other end of the connecting rod is fixedly connected to a sliding column. The two ends of the sliding column are slidably connected to the inside of the long through groove. A driving assembly is provided at the bottom of the groove.

[0008] Preferably, the drive assembly described above includes two electric push rods, which are fixedly connected inside the groove. Each push rod end of the two electric push rods is fixedly connected to a connecting block, which is movably sleeved on the outside of the slide column and located inside the other end of the connecting rod.

[0009] Preferably, two through-beam photoelectric switches are installed on the inner sides of the window frame below the rear side of the movable window, and the electrical output terminal of the through-beam photoelectric switch is connected to the electrical input terminal of two electric push rods.

[0010] Preferably, a support plate is fixedly connected to one end of the inner side of the groove, a sealing strip is fixedly connected to the top of the support plate, and the bottom side of the cover plate abuts against the top of the sealing strip.

[0011] Preferably, the window frame described above has guide grooves on both inner sides, a sliding groove at the bottom of the guide groove, a lead screw rotatably connected inside the sliding groove, a slider movably sleeved on the outside of the lead screw, and the movable window is fixedly connected to one side of the slider.

[0012] Preferably, the slider is slidably connected inside the groove, and the slider is threadedly connected to the outside of the lead screw.

[0013] Preferably, right-angle reducers are installed at both ends of the top of the window frame, the output end of the right-angle reducer is connected to a lead screw extending to one end of the top of the window frame, servo motors are installed at both ends of the top of the window frame, the output shafts of the two servo motors are respectively installed on the right-angle reducers, and the electrical signal output end of the through-beam photoelectric switch is connected to the electrical signal input end of the two servo motors.

[0014] Preferably, a servo controller is installed at the top of the window frame, and the electrical signal output terminal of the servo controller is connected to the electrical signal input terminals of the two servo motors respectively.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] When a person's palm is placed on the crossbeam of the window frame, the signal of the through-beam photoelectric switch is blocked. At this time, the through-beam photoelectric switch controls the two servo motors to stop running, and the sliding window stops descending, thus ensuring the safety of the person. At the same time, the through-beam photoelectric switch controls the push rods of the two electric push rods to extend. The push rods of the electric push rods drive the cover plate to rotate around the fixed axis through the connecting rod, thereby bringing the person's palm away from the bottom of the sliding window. This provides double protection, preventing injury to the person's body caused by the sliding window due to servo controller failure, and improving the safety of using the lifting window.

[0027] Example

[0028] In the existing technology, electric lifting windows are usually controlled by a servo motor driving a screw mechanism to achieve window lifting and lowering, and by using photoelectric sensors to detect obstacles and stop the machine. However, a single protection mechanism has the risk of failure. When the sliding window is lowered, the photoelectric switch detects a person's palm and the system can stop the motor. However, if the servo controller fails or the mechanical system jams, the window may still cause the person's palm to be crushed due to gravity as it slides down.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a glass-embedded lift window, including a window frame 1, a glass 2 embedded in the front side of the window frame 1, edge strips 3 snapped onto the four sides of the glass 2 on the window frame 1, a movable window 8 provided on the inner side of the window frame 1 and the rear side of the glass 2, and a protective component provided on the crossbeam of the window frame 1.

[0030] By incorporating protective components, double protection is provided, enhancing the safety of the window's operation. The protective components include a fixed shaft 14, a cover plate 15, and two fixing seats 16. A groove 13 is formed at the top of the crossbeam of the window frame 1. The fixed shaft 14 is fixedly connected to the inside of the groove 13. The cover plate 15 is movably connected to the outside of the fixed shaft 14. The two fixing seats 16 are fixedly connected to the bottom of the cover plate 15. One end of a connecting rod 17 is hinged to the outside of the two fixing seats 16. Two U-shaped grooves are fixedly connected to the bottom of the groove 13. The body 18 has long through slots 19 on both sides. The other end of the connecting rod 17 is fixedly connected to a sliding column 20. The two ends of the sliding column 20 are slidably connected to the inside of the long through slot 19. The sliding column 20 drives the other end of the connecting rod 17 to move, thereby pushing one end of the connecting rod 17 to drive the cover plate 15 to rotate around the fixed shaft 14, thereby taking the person's palm away from the bottom of the movable window 8. This provides double protection to prevent the servo controller 11 from causing injury to the person's body due to malfunction. The bottom of the groove 13 is provided with a drive component.

[0031] The drive assembly provides power for the flipping of the cover plate 15. The two electric push rods 21 are fixedly connected inside the groove 13. Each push rod end of the two electric push rods 21 is fixedly connected to a connecting block. The connecting block is movably sleeved on the outside of the sliding column 20. The connecting block is located inside the other end of the connecting rod 17. Two through-beam photoelectric switches 12 are installed on the two inner sides of the window frame 1 below the rear side of the movable window 8. The electrical output terminal of the through-beam photoelectric switch 12 is connected to the electrical input terminal of the two electric push rods 21. When a person's palm is placed on the crossbeam of the window frame 1, the signal of the through-beam photoelectric switch 12 is blocked. The through-beam photoelectric switch 12 controls the push rods of the two electric push rods 21 to extend. The push rods of the electric push rods 21 drive the sliding column 20 to move inside the long through groove 19 through the connecting block. At this time, the sliding column 20 pushes the cover plate 15 to rotate around the fixed shaft 14 through the connecting rod 17.

[0032] A support plate 22 is fixedly connected to one end of the inner side of the groove 13, and a sealing strip 23 is fixedly connected to the top of the support plate 22. The bottom side of the cover plate 15 abuts against the top of the sealing strip 23. The sealing strip 23 can improve the sealing performance of the groove 13 and prevent external dust or sewage from entering the interior of the groove 13. Since the side of the cover plate 15 is on the outside, the sealing strip 23 is provided.

[0033] To improve the safety of the lifting window, guide grooves 4 are provided on both inner sides of the window frame 1, and sliding grooves 5 are provided at the bottom of the guide grooves 4. A lead screw 6 is rotatably connected inside the sliding groove 5. A lead screw protective cover is installed on the outside of the lead screw 6 to prevent the lead screw 6 from getting stuck due to dust. A slider 7 is movably sleeved on the outside of the lead screw 6. The movable window 8 is fixedly connected to one side of the slider 7. The slider 7 is slidably connected inside the sliding groove 5. The slider 7 is threaded to the outside of the lead screw 6. Right angle reducers 9 are installed at both ends of the top of the window frame 1. The output end of the right angle reducer 9 is connected to the lead screw 6 extending to one end of the top of the window frame 1. Servo motors 1 are installed at both ends of the top of the window frame 1. The output shafts of the two servo motors 10 are respectively mounted on the right-angle reducer 9. The electrical signal output terminal of the through-beam photoelectric switch 12 is connected to the electrical signal input terminal of the two servo motors 10. During the descent of the movable window 8, when a person's palm is placed on the crossbeam of the window frame 1, the signal of the through-beam photoelectric switch 12 is blocked. At this time, the through-beam photoelectric switch 12 controls the two servo motors 10 to stop running, and the movable window 8 stops descending, thereby ensuring the safety of the personnel. The through-beam photoelectric switch 12 consists of a projector and a receiver. Structurally, the two are separate from each other. Its structural principle and working principle are existing technologies and will not be described in detail here.

[0034] A servo controller 11 is installed at the top of the window frame 1. The electrical signal output terminal of the servo controller 11 is connected to the electrical signal input terminal of the two servo motors 10 respectively. When it is necessary to raise or lower the movable window 8, the servo controller 11 outputs an electrical signal to control the two servo motors 10 to start. The output shaft of the servo motor 10 drives the two lead screws 6 to rotate simultaneously through the right angle reducer 9. The two lead screws 6 simultaneously drive the sliders 7 to move inside the slide groove 5, so that the two sliders 7 drive the movable window 8 to rise or fall. The model of the servo controller 11 is CNS-SF50HB. Its structure and working principle are existing technologies and will not be described in detail here.

[0035] The working principle or structural principle is as follows: When the sliding window 8 needs to be raised or lowered, the servo controller 11 outputs an electrical signal to control the two servo motors 10 to start. The output shafts of the servo motors 10 drive the two lead screws 6 to rotate simultaneously through the right-angle reducer 9. The two lead screws 6 simultaneously drive the sliders 7 to move inside the slide groove 5, so that the two sliders 7 drive the sliding window 8 to rise or fall. During the descent, when a person's palm is placed on the crossbeam of the window frame 1, the signal of the through-beam photoelectric switch 12 is blocked. At this time, the through-beam photoelectric switch 12 controls the two servo motors 10 to stop running, and the sliding window 8 stops descending. This provides a guarantee for personnel safety. When the two servo motors 10 stop running, the through-beam photoelectric switch 12 controls the extension of the push rods of the two electric push rods 21. The push rods of the electric push rods 21 drive the sliding column 20 to move inside the long through groove 19 through the connecting block. At this time, the sliding column 20 drives the other end of the connecting rod 17 to move, thereby pushing one end of the connecting rod 17 to drive the cover plate 15 to rotate around the fixed shaft 14, thereby taking the person's palm away from the bottom of the moving window 8. This provides double protection to prevent the servo controller 11 from causing injury to the person's body due to failure, and improves the safety of using the lifting window.
