Description

Automatic window opening and closing device

Technical Field

The utility model relates to the technical field of windows, in particular to an automatic opening and closing window device.

Background technique

As one of the essential elements of architecture since ancient times, windows not only have the functions of lighting and ventilation, but also have many functions such as heat preservation, heat insulation, noise reduction, and anti-theft. With the development of modern society, their materials have also developed from wooden windows and paper windows to today's aluminum alloy windows, plastic windows, fiberglass windows and other types. Windows play an indispensable role in people's daily life. They can not only provide necessary light and air, but also affect the indoor environment, safety and aesthetics.

Manually opened and closed windows are the most common, and have been used by people for hundreds of years. Windows need to be closed on rainy days to prevent rain from entering the room under the action of wind and causing damage to furniture, home appliances and other items. However, in daily life, people often forget to close the windows before going out. If it suddenly rains heavily, rain will enter the house through the windows, causing a mess indoors. If it rains heavily in the middle of the night, people have to wake up from their sleep to close the windows, which affects people's sleep quality and brings great inconvenience to people's daily routines.

Nowadays, there is no shortage of windows that can open and close automatically, and windows that sense rain and close automatically are already quite common. However, in actual use, in order to sense rain or wind, raindrop sensors or wind sensors are always exposed outdoors, that is, in continuous rainy or windy weather, the control system always sends a command to close the window. This may not only cause mechanical loss to the servo arm, but also consume power resources, which is not conducive to long-term use and operation.

Utility Model Content

The utility model provides an automatic window opening and closing device in order to solve the above technical problems.

In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

An automatic window opening and closing device comprises a window body, a sensing mechanism and a folding arm type electric window opener, wherein the window body comprises a window frame and a window opened outwards through a hinge, and the folding arm type electric window opener comprises a main body, a steering gear arm and a slide slot frame, wherein the main body is arranged at the outer top of the window, the slide slot frame is horizontally arranged at the outer top of the window frame, a first slide slot is arranged parallel to the upper side of the slide slot frame, the sensing mechanism is slidably connected to the first slide slot, the slide slot frame is provided with a through slot in the height direction, a second slide slot is provided on the inner wall of the through slot in the length direction, and one end of the steering gear arm is connected to the main body rotation The window frame is dynamically connected, and a roller is provided at the other end of the servo arm, and the roller is slidably connected in the second slide groove. The free end of the servo arm is connected to the bottom of the roller, and the top of the roller is fixedly connected to the sensing mechanism through a connecting rod. The sensing mechanism includes a raindrop sensor, a wind speed sensor and a wireless transmission module, and the wireless transmission module is wirelessly connected to the main body. A shielding cover is also provided on the window frame, and the opening of the shielding cover faces the window frame. The shielding cover covers the right side of the slide groove frame and the first slide groove, and an opening for the sensing mechanism to pass through begins on the left side of the shielding cover.

Furthermore, the sensing mechanism includes a bracket for mounting a raindrop sensor and a wind speed sensor, wherein the sensing plate of the raindrop sensor is arranged at the top of the bracket, and the fan blade of the wind speed sensor is arranged at the bottom of the bracket. When raindrops fall on the sensing plate, it forms an electrical conductance path between the electrodes, so that the resistance is reduced and the current can flow. The raindrop sensor measures the change in current to determine whether rain has fallen on the sensor, and these changes can be converted into electrical signals and then transmitted to the control system of the main body. When the wind blows through the fan blades, they are pushed, and the speed of rotation is proportional to the wind speed. By setting a threshold value for the rotation speed, when the set threshold value is exceeded, the corresponding electrical signal is transmitted to the control system of the main body, thereby realizing the operation of automatically closing the window.

Furthermore, the roller is a bearing including an inner ring and an outer ring, the free end of the servo arm is connected to the bottom of the inner ring, and the bottom of the linkage rod is connected to the top of the inner ring. When the servo arm rotates, the free end of the servo arm slides in the second slide groove through the roller, and the distance between the window and the window frame changes during the sliding process. During the movement of the free end of the servo arm, the sensing mechanism follows the horizontal movement through the linkage rod.

Furthermore, the length, width and height of the shielding cover are all greater than the length, width and height of the sensing mechanism. When the sensing mechanism enters the shielding cover, the various components of the sensing mechanism will not collide with the shielding cover and can be completely received therein.

Furthermore, a solar power panel is installed on the main body and the sensing mechanism, and the solar power panel passes through the housing of the main body and the sensing mechanism respectively and is electrically connected to the internal power supply system. The solar power panel is fixed to the mounting frame by bolts, and then the output cable of the solar power panel is connected to the input cable of the electric window opener or the sensing mechanism.

Furthermore, the shells of the main body and the shielding cover are both made of waterproof material.

Furthermore, the main body is also provided with a current sensor and a Hall sensor for monitoring the movement state of the window. If the window is clamped by an object or resistance occurs, the current and the rotation speed will change. At this time, the control system will issue a command based on the feedback to reverse the current direction of the folding arm electric window opener. By changing the current direction, the servo arm will stop or reverse movement, thereby avoiding clamping a person or object.

Furthermore, a wireless communication module connected to the sensing mechanism and the communication device is installed inside the main body, and the wireless communication module is electrically connected to the control system. The mobile phone App is connected to the control system of the window through the wireless communication module, and then the mobile phone App sends instructions to the control system, and the control system controls the opening and closing state of the window according to the instructions. At the same time, the control system can send feedback information to the mobile phone App to inform the current state of the window to ensure that the user can accurately understand the position of the window.

Compared with the prior art, the utility model has the following beneficial effects:

1. When the window is closed, the sensing mechanism can be brought into the shielding cover to isolate it from the external weather, thereby reducing the detection energy consumption and operating loss, increasing the service life of the equipment and reducing the maintenance frequency;

Embodiment 1

As shown in Figures 1, 2, 3 and 4, an automatic window opening and closing device disclosed in the utility model comprises a window body, a sensing mechanism 6 and a folding-arm electric window opener, wherein the window body comprises a window frame 1 and a window 2 opened outward by hinges, and the folding-arm electric window opener comprises a main body 3, a servo arm 4 and a slide slot frame 5, wherein the main body 3 is arranged at the outer top of the window 2, the slide slot frame 5 is horizontally arranged at the outer top of the window frame 1, a first slide slot 7 is arranged parallel to the upper side of the slide slot frame 5, the sensing mechanism 6 is slidably connected to the first slide slot 7, the slide slot frame 5 is provided with a through slot 8 in the height direction, the through slot 8 is provided with a second slide slot 9 on the inner wall in the length direction, one end of the servo arm 4 is connected to the The main body 3 is rotatably connected, and a roller 10 is provided at the other end of the servo arm 4. The roller 10 is slidably connected in the second slide groove 9. The free end of the servo arm 4 is connected to the bottom of the roller 10. The top of the roller 10 is fixedly connected to the sensing mechanism 6 through a connecting rod 11. The sensing mechanism 6 includes a raindrop sensor, a wind speed sensor and a wireless transmission module. The wireless transmission module is wirelessly connected to the main body 3. A shielding cover 12 is also provided on the window frame 1. The opening of the shielding cover 12 faces the window frame 1. The shielding cover 12 covers the right side of the slide groove frame 5 and the first slide groove 7. The left side of the shielding cover 12 begins to have an opening for the sensing mechanism 6 to pass through.

The sensing mechanism 6 includes a bracket 13 for mounting a raindrop sensor and a wind speed sensor, a sensing plate 14 of the raindrop sensor is arranged at the top of the bracket 13, and a fan blade 15 of the wind speed sensor is arranged at the bottom of the bracket 13. Specifically, the working principle of the raindrop sensor is that in clear weather, the resistance of the sensing plate 14 is very high and it is difficult for the current to pass through. However, when raindrops fall on the sensing plate 14, it will form an electrical conductance path between the electrodes, so that the resistance is reduced and the current can flow through. The raindrop sensor measures the change in current to determine whether rain falls on the sensor. These changes can be converted into electrical signals and then transmitted to the control system of the main body 3, thereby realizing the automatic window closing operation. The working principle of the wind speed sensor is that through the multiple rotating fan blades 15 installed on the bracket 13, when the wind blows through the fan blades 15, they will be pushed, and the speed of rotation is proportional to the wind speed. By setting the threshold of the rotation speed, when the set threshold is exceeded, the corresponding electrical signal is transmitted to the control system of the main body 3, thereby realizing the automatic window closing operation.

The roller 10 is a bearing including an inner ring and an outer ring. The free end of the servo arm 4 is connected to the bottom of the inner ring, and the bottom of the linkage rod 11 is connected to the top of the inner ring. Specifically, the servo arm 4 is controlled by a servo motor arranged inside the main body 3, and rotates in a corresponding direction after receiving an instruction from the control system. When the servo arm 4 rotates, the free end of the servo arm 4 slides in the second slide groove 9 through the roller 10. During the sliding process, the distance between the window 2 and the window frame 1 changes accordingly. During the movement of the free end of the servo arm 4, the sensing mechanism 6 follows the horizontal movement through the linkage rod 11.

The length, width and height of the shielding cover 12 are all greater than the length, width and height of the sensing mechanism 6. Specifically, when the sensing mechanism 6 enters the shielding cover 12, the various components of the sensing mechanism 6 will not collide with the shielding cover 12, and can be completely retracted therein, so that the sensing plate 14 and the fan blade 15 on the bracket 13 are in a relatively closed space and no signal command is generated. Preferably, the inner side wall of the shielding cover 12 is also provided with a protruding baffle, which does not affect the sliding of the sensing mechanism 6 on the first slide groove 7, but can block the rotation of the fan blade 15, that is, when strong wind rushes into the shielding cover 12, the fan blade 15 will not rotate to generate a signal command.

Solar power panels are installed on the main body 3 and the sensing mechanism 6, and the solar power panels pass through the shells of the main body 3 and the sensing mechanism 6 respectively and are electrically connected to the internal power supply system. Specifically, first, determine the optimal lighting installation position of the solar power panel, and then fix the solar power panel with screws through the mounting frame. Then connect the output cable of the solar power panel to the input cable of the electric window opener or the sensing mechanism 6. Preferably, a solar controller is provided to better manage the charging and distribution of solar energy. This can ensure that the battery or energy storage system is properly charged and supply power to the electric window opener and the sensing mechanism 6 as needed.

The housings of the main body and the shielding cover 12 are both made of waterproof material.

The main body is also provided with a current sensor and a Hall sensor for monitoring the movement state of the window. Specifically, when the window 2 executes the opening and closing command, the folding arm electric window opener starts to work, and the current sensor monitors the working current of the folding arm electric window opener in real time, while the Hall sensor monitors the rotation speed of the folding arm electric window opener. If the window 2 clamps an object or resistance, the current and rotation speed will change. At this time, the control system will issue a command based on the feedback to reverse the current direction of the folding arm electric window opener. By changing the direction of the current, the servo arm 4 will stop or move in the opposite direction, thereby avoiding clamping a human body or object.

A wireless communication module connected to the sensing mechanism 6 and the communication device is installed inside the main body 3, and the wireless communication module is electrically connected to the control system. Specifically, the mobile phone App is connected to the control system of the window 2 through the wireless communication module, which can be achieved through communication technologies such as Wi-Fi, Bluetooth, Zigbee, etc. Then the mobile phone App sends instructions to the control system, and the control system controls the opening and closing state of the window 2 according to the instructions. At the same time, the control system can send feedback information to the mobile phone App to inform the current state of the window 2 to ensure that the user can accurately understand the position of the window 2. This can greatly improve the convenience and safety of operation for, for example, the elderly, children, the disabled, etc., and can well avoid accidents such as pinching and falling stools.

Based on the first embodiment, this embodiment proposes a specific working principle of an automatic window opening and closing device.

The specific implementation principle process is as follows:

When the window 2 is in the open state, the sensing mechanism 6 is exposed to the outdoor environment and monitors the rain and strong wind at any time. If it rains or the speed of the fan blade 15 is greater than a certain set threshold, the sensing mechanism 6 sends an electrical signal to the wireless communication module on the main body 3 through the wireless transmission module, and transmits it to the control system, and the steering gear arm 4 starts to rotate. During the rotation, the roller 10 slides to the right in the second slide groove 9, and at the same time drives the sensing mechanism 6 to move to the right until the window 2 is completely closed, and the sensing mechanism 6 is located in the shielding cover 12. During the rotation of the steering gear arm 4, if there is resistance or it touches an object, the steering gear arm 4 will stop or move in the opposite direction to avoid clamping a person or an object.

When the window 2 is in the closed state, the sensing mechanism 6 is located in the shielding cover 12, and the raindrop sensor and the wind speed sensor will not send electrical signal instructions, thereby reducing energy consumption and protecting the raindrop sensor and the wind speed sensor from long-term wind and rain, thereby preventing the equipment from being damaged by bad weather. When the weather improves, the window 2 can be opened manually or through a mobile phone app.

Of course, the present invention may have many other implementation modes. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
