Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide an external window that automatically opens without any human action or external force when power is off, so as to solve the technical problems existing in the above-mentioned prior art. When there is power, the opening or closing of the movable window can be controlled, and the movable window can be positioned and hovered at any time, and the movable window can be automatically opened when power is off.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-4 As shown, this embodiment provides an external window that automatically opens without any human action or external force when the power is off, including a window frame 1, a movable window 2, a fixed window 3, a slide rail 4, a slider 5, a lifting device, a controller and a power supply. The movable window 2 is slidably connected to the window frame 1, and the fixed window 3 is fixed to the window frame 1. The movable window 2 is located above the fixed window 3 when sealed. The four sides of the movable window 2 and the fixed window 3 are made of aluminum alloy, and the middle is glass. There are multiple sliders 5, and the sliders 5 are fixed on the side walls of the movable window 2. The slide rail 4 is fixed on the inner wall of the window frame 1, and the slide rail 4 guides the sliders 5. The lifting device is fixed on the movable window 2. The function of the lifting device is to drive the movable window 2 to move up and down. Those skilled in the art can select the lifting device according to actual needs, such as a telescopic rod, a cylinder, an electric push rod, a hydraulic push rod, a pneumatic push rod, a chain push rod and other devices with lifting functions. The lifting device is electrically connected to the controller, and the lifting device is controlled to rise or fall by the controller. The controller is electrically connected to the power supply, and the power supply provides a power source for the controller.

[0030] When in use, the resident can control the start or stop of the lifting device through the controller, and the rise or fall of the lifting device drives the movable window 2 to rise or fall, and the resident can open or close the movable window 2 according to their needs. In addition, the resident can also adjust the lifting height of the movable window 2 according to their needs, thereby adjusting the size of the vent. When a fire occurs, the lifting device fails, and the movable window 2 can fall by its own weight, thereby realizing the opening of the movable window 2.

[0031] In this embodiment, the slide rail 4 includes a vertical portion and an inclined portion, and the inclined portion is fixed to the upper end of the vertical portion. When the movable window 2 is in the process of rising or falling, the slider 5 is on the vertical portion, and the movable window 2 and the fixed window 3 are not on the same vertical plane. When the movable window 2 needs to be closed, the movable window 2 is driven up by the lifting device, and when it enters the inclined portion, the movable window 2 gradually fits the fixed window 3, so that the movable window 2 and the fixed window 3 are on the same vertical plane, improving the sealing effect.

[0032] As for the sliders 5 and the slide rails 4, in this embodiment, there are four sliders 5 and four slide rails 4, the sliders 5 are respectively fixed to the upper and lower ends of both sides of the movable window 2, and the slide rails 4 are respectively symmetrically fixed to both sides of the window frame 1, and each slider 5 corresponds to a slide rail 4. The vertical parts of the two slide rails 4 on one side are distributed up and down, so that the upper and lower ends of the movable window 2 are always on the same vertical plane.

[0033] As for the lifting device, in this embodiment, the lifting device includes a motor 6, a screw rod 7, a screw rod fixing seat 8 and a motor fixing seat 9. The output end of the motor 6 is fixed to the first end of the screw rod 7, and the motor 6 drives the screw rod 7 to rotate. One side of the movable window 2 has a through channel, and the second end of the screw rod 7 passes through the through channel. The inner diameter of the through channel is larger than the diameter of the screw rod 7, so that the screw rod 7 can be prevented from colliding with the inner wall of the through channel during the rotation process. The screw rod fixing seat 8 is hinged to the bottom of the movable window 2, and the screw rod fixing seat 8 has an internal thread. The screw rod fixing seat 8 is threadedly connected with the screw rod 7. When in use, the screw rod 7 rotates to drive the screw rod fixing seat 8 to move up and down, and then the screw rod fixing seat 8 drives the movable window 2 to move up and down. The motor 6 is fixed to the first end of the motor fixing seat 9, and the second end of the motor fixing seat 9 is hinged to the bottom of the window frame 1. The function of the hinge connection between the screw rod fixing seat 8 and the motor fixing seat 9 is that when the slider 5 enters the inclined portion from the vertical portion, the vertical plane where the movable window 2 is located will move. In order to match the movable window 2, the screw rod 7 must also be offset at a certain angle, so the hinge connection is adopted. The motor 6 is electrically connected to the controller, and the controller controls the start of the motor 6.

[0034] In order to realize the hinge connection of the screw fixing seat 8 and the motor fixing seat 9, the present embodiment further includes a fixing block 10, and there are multiple fixing blocks 10, two fixing blocks 10 form a group, and the number of groups of fixing blocks 10 is the same as the number of screw fixing seats 8 and motor fixing seats 9. The fixing blocks 10 are fixed to the bottom of the movable window 2 and the bottom of the window frame 1, that is, each group of fixing blocks 10 is respectively located on both sides of the screw fixing seat 8 or the motor fixing seat 9, and the two ends of the screw fixing seat 8 and the motor fixing seat 9 are respectively hinged to a fixing block 10.

[0035] Further, there are two sets of lifting devices, which are fixed on both sides of the movable window 2, and through channels are provided on both sides of the movable window 2. The movable window 2 is driven up and down by the two sets of lifting devices at the same time, so as to avoid unilateral force on the movable window 2.

[0036] In order to prevent external dust from entering the screw 7 and the motor 6, the present embodiment also includes a motor protection cover 12 and two screw protection covers 11. The motor protection cover 12 is fixed to the bottom of the window frame 1, and the two motors 6 are located in the motor protection cover 12. The motor protection cover 12 is a C-shaped plate. The open end of the motor protection cover 12 is fixed to the bottom of the window frame 1, and the two sides of the motor protection cover 12 are closed, so that the motor 6 can be isolated from the outside. The two screw protection covers 11 are respectively fixed to the two sides of the inner wall of the window frame 1, and the two screws 7 are respectively located in the two screw protection covers 11. Each screw protection cover 11 includes two baffles, and the two baffles are respectively fixed to the two sides of the screw 7.

[0037] In this embodiment, a window seat 13 is further included, and the window seat 13 is fixed to the upper end of the fixed window 3. The window seat 13 is a rectangular frame, and when the movable window 2 rises to the highest point, the window seat 13 cooperates with the movable window 2 to achieve sealing.

[0038] Furthermore, in order to achieve a close fit between the movable window 2 and the window seat 13, in this embodiment, a plurality of electromagnets 14 are fixed on the movable window 2 and the window seat 13, and the electromagnets of the movable window 2 and the window seat 13 are directly opposite, and the electromagnets 14 are electrically connected to the controller. When the movable window 2 rises to the position of the window seat 13, the movable window 2 is firmly adsorbed on the window seat 13 by the electromagnets 14. When the movable window 2 descends, the controller cuts off the power of the electromagnet 14 and then controls the motor 6 to make the movable window 2 descend. When the power is cut off, the motor 6 has no power source, and the electromagnet 14 has no power source and cannot be electromagnetically attracted. The movable window 2 can descend by its own gravity, thereby creating a large-area smoke exhaust window and escape exit.

[0039] In order to realize multifunctional control, in this embodiment, the controller is also electrically connected to the temperature release device, smoke detector, fire detector, gas leak detector, outdoor temperature air quality detector, outdoor rain detector, indoor air quality detector, indoor carbon dioxide concentration detector, indoor oxygen content detector, Bluetooth detector, infrared detector, etc., and the environment is detected by the above multiple sensors, and the data can be transmitted to the controller in real time. The controller transmits the data to the cloud server, mobile phone, fire rescue agency, building fire protection system and property in real time. The opening and closing instructions received by the controller can be issued by human remote control, and the controller can also receive control instructions and send signals to open and close the outer window through various forms such as on-site switches, mobile phones, software analysis, data algorithms or fire protection system triggers. The controller can also accurately control the two motors 6 to rotate at the same time. The connection between the fingerprint identifier and the controller is to realize fixed person control, and only the designated person can decide whether to open and close the movable window 2. The purpose of the electrical connection between the emergency button and the controller is that when a fire occurs, it may be too late to control the controller. At this time, pressing the emergency button opens the movable window 2 to facilitate the escape of the residents. The mobile phone is electrically connected to the controller, which can realize remote control of the residents. When the residents are going home and need to ventilate in advance, they can use the mobile phone to remotely control the movable window 2 to open for ventilation. The camera is electrically connected to the controller, which can realize timely closing of the window and alarm and notify the property and the owner when there is any abnormal movement outside the window. The controller is also electrically connected to the backup power supply to prevent the original power supply from being out of power or damaged, and the backup power supply can be switched immediately. When both the original power supply and the backup power supply fail, the movable window 2 can be automatically opened without any human action or any external force, which realizes the advantages of efficiently removing smoke inside the building during a fire and facilitating the rescue of firefighters and the escape of personnel.
