Description

Technical Field

[0001] This utility model belongs to the field of window opening technology, and particularly relates to a chain-type electric window opener. Background Technology

[0002] With societal development, residents have increasingly higher demands for the quality of their home environment. Window openers, as part of home automation, are widely used for ventilation in indoor spaces. Currently, there are various types of window openers, among which the chain-type window opener is particularly practical. It has a very compact structure, and during operation, the chain can bend and retract into the small window opener or extend to vertically support the window sash. Its appearance achieves symmetrical coordination with the window frame, greatly improving the overall visual effect of the window.

[0003] Utility model patent with publication number CN221032129U discloses a chain-type electric window opener, relating to the field of electric window opener technology. It includes a window opener housing, with two sets of chain outlets positioned opposite each other on the front side of the window opener housing. The chain outlets are equipped with chains, and a movable shaft is equipped on the front side of the chains. Clamping blocks are hinged to both ends of the movable shaft, and a rotating shaft is fixedly installed between the two sets of clamping blocks. The movable shaft is fitted onto the outer wall of the rotating shaft, and a window frame is fixedly installed on the front side of the clamping blocks. Two sets of brushes are fixedly installed on the outer wall of the front side of the window opener housing, with the brushes positioned opposite to the chains.

[0034] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0035] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] Example 1:

[0037] like Figures 1-5 As shown, this embodiment provides a chain-type electric window opener, including:

[0038] The window opener housing 1 has bases 2 on both its left and right sides;

[0039] The electric drive unit 3 includes a motor 31, a motor control board 32, and a control system 35. The motor 31 and the motor control board 32 are disposed inside the window opener housing 1. The motor control board 32 is electrically connected to the motor 31. The control system 35 includes a microprocessor 351 and at least one interface 352 for receiving external signals.

[0040] One end of the chain 4 is connected to the output end of the motor 31. The motor 31 transmits power to the chain 4, causing the chain 4 to extend or retract to realize the opening and closing action of the window. The other end is connected to the window through at least one adjustable connector 41.

[0041] Outlet 5, located on the window opener housing 1, is used for the extension or retraction of chain 4;

[0042] The control panel 6 is equipped with a touch screen display 61, through which the user operates. The control panel 6 also includes a wireless communication module 62, which can receive remote control signals and send window status data.

[0043] The environmental monitoring unit 7 includes a photosensitive sensor 71, a temperature sensor 72, a wind speed sensor 73, and a rain sensor 74, so as to automatically adjust the opening or closing status of the window according to real-time environmental data. The environmental monitoring unit 7 also includes a control unit 8.

[0044] The control unit 8 is electrically connected to the photosensitive sensor 71, temperature sensor 72, wind speed sensor 73 and rain sensor 74. The control system 35 controls the electric drive unit 3 to drive the chain 4 to adjust the opening or closing state of the window according to the environmental index information. The control system 35 is electrically connected to the control panel 6.

[0045] In this technical solution, the chain-type electric window opener provides an automated and intelligent window operation solution, enabling users to easily control the opening and closing of windows via touch screen or remote control. At the same time, it automatically adjusts the window status based on environmental data to optimize the indoor climate and enhance the comfort and energy efficiency of the living or working environment, enabling it to automatically adjust the opening or closing status of windows based on real-time environmental data.

[0046] Function details:

[0047] Electric drive unit 3: Using stepper motor 31, it provides precise control capabilities and can adjust the opening angle or position of the window as needed.

[0048] Motor control board 32: manages the power supply and operating mode of motor 31, ensuring that motor 31 operates efficiently according to the instructions of control system 35.

[0049] Control system 35: Built-in microprocessor 351 and interface 352, receive and process external signals (such as touch screen input or remote commands) to control the movement of motor 31.

[0050] One end of the chain 4 is connected to the output of the motor 31, and the other end is connected to the window via an adjustable connector 41. When the motor 31 is running, it transmits power to the chain 4 to open or close the window.

[0051] The control panel 6 includes a touchscreen display 61, allowing users to operate directly on the touchscreen, such as setting the window opening degree and timer settings. It also includes a wireless communication module 62, which can receive remote control signals and send window status data, enabling users to control the windows remotely.

[0052] The environmental monitoring unit 7 integrates a photosensor 71, a temperature sensor 72, a wind speed sensor 73, and a rainfall sensor 74 to monitor external environmental conditions in real time. The control unit 8 consists of a calculation module, a data comparison module, and a data transmission module. The control unit 8 processes the data collected from the sensors, the calculation module calculates environmental indices, the data comparison module compares and analyzes the results, and the data transmission module feeds the information back to the main control system 35.

[0053] Workflow: Users issue commands to open or close windows via touchscreen or remote control. Control system 35 receives the commands, processes the signals, and drives electric drive unit 3 to operate chain 4 via motor 31, achieving precise opening or closing of the window. Chain 4 extends or retracts to achieve the opening and closing action of the window. Environmental monitoring unit 7 monitors the external environment in real time, such as light intensity, temperature, wind speed, and rainfall. Control unit 8 calculates and compares environmental data. If an increase in rainfall is detected, it automatically sends a signal to control system 35 to instruct the window to close. Control system 35 automatically adjusts the window status according to environmental monitoring data or user settings to ensure the comfort and safety of the indoor environment. This design not only provides the convenience of manual and remote control for chain-type electric window openers, but also adds automated adjustment functions for living and working environments through intelligent environmental response.

[0054] Specifically, the chain-type motorized window opener is equipped with a photosensor 71, a temperature sensor 72, a wind speed sensor 73, and a rain sensor 74. These sensors monitor changes in the surrounding environment in real time. The photosensor 71 measures the intensity of external light to determine whether to automatically open the window to utilize natural light when there is sufficient sunlight, or to close the window after sunset. The temperature sensor 72 monitors the external temperature and can adjust the window opening degree when the temperature is too high or too low to maintain a comfortable indoor temperature. The wind speed sensor 73 measures the external wind speed to prevent the window from being opened when the wind is too strong, thus avoiding damage or inconvenience. The rain sensor 74 senses rainfall and automatically closes the window when it starts to rain to prevent rainwater from entering the room and to prevent the window opener from being hit by rainwater, thus extending the lifespan of the window opener. All data received from the sensors is sent to the computing module of the control unit 8, which analyzes and processes the data to provide decision support for opening or closing the window. The calculation module first receives and analyzes all sensor data, converting it into real-time environmental indices. The data comparison module evaluates the calculation results and compares them with preset environmental parameter thresholds to determine whether window adjustments are needed. Once the data comparison module decides that window adjustments are necessary, this decision is transmitted to the main control system 35 via the data transmission module. The control system 35 then instructs the electric drive unit 3 to operate the chain 4 via the motor 31, achieving precise opening or closing of the window. This process is automatic and requires no manual intervention. Although the system operates automatically, users can still manually control the window status or modify automatic control parameter settings, such as adjusting the sensitivity settings for light or temperature, via the touchscreen control panel 6 or the wireless communication module. The chain-type electric window opener, through an integrated sensor network and intelligent control unit 8, can automatically adjust the window to adapt to environmental changes, improving the comfort of the living or working environment and increasing energy efficiency. It also prevents the window opener from being affected by rain, making it less prone to rust and extending its service life, resulting in more stable window opening and closing.

[0055] Example 2:

[0056] This embodiment provides a chain-type electric window opener, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0057] like Figure 5 As shown, in this embodiment, the optimized control system 35 can receive commands from the smart home system via a wireless network to achieve automated window control, including but not limited to operation via an application or voice commands.

[0058] In this technical solution, the system integrates with a smart home system through a wireless network, enabling broader automation control. This allows windows to not only automatically adjust in response to environmental changes, but also to be controlled via direct user input (such as applications or voice commands).

[0059] The goal is to enable users to directly control windows via smart devices (such as smartphones, tablets, or smart speakers) without physical contact, providing greater operational convenience. Integration with smart home systems allows window control to work in tandem with other smart devices in the home, such as air conditioning and lighting, achieving comprehensive intelligent environmental management. Users can set specific scenes or scenarios, such as "Away Mode" to automatically close all windows, or "Night Mode" to reduce window opening levels for security and privacy.

[0060] Workflow: The control panel 6 within the window opener includes a wireless communication module capable of connecting to the home's wireless network. Through this network, the window opener can communicate with the home's smart home hub or directly with devices such as smartphones. Users can issue commands via a smart home system app or a voice assistant, such as "open the living room window" or "open all windows halfway." The smart home system translates these commands into specific signals and sends them to the window opener's control system 35 via the wireless network. Upon receiving the command, the control system 35 directs the motor 31 via its internal motor control board 32. The motor 31 then transmits power to the chain 4 to adjust the window's opening and closing status. If the command involves environmental sensing, the system also references real-time data from the environmental monitoring unit 7 to ensure the operation is environmentally suitable and safe. After completing the operation, the control system 35 can send a window status update to the smart home system via the wireless communication module, confirming successful operation or reporting any problems. Users can check the window status at any time through the application and get real-time feedback. Through the integration with the smart home system via wireless network, the chain-type electric window opener not only realizes automatic response based on environmental sensors, but can also be operated through direct user commands, which greatly increases the interactivity of the system and the user's control flexibility. This integration method provides an efficient and convenient management solution for modern smart buildings.

[0061] like Figure 5 As shown, in this embodiment, the optimized electric drive unit 3 includes a position sensor 36, which can accurately measure the angle or distance of the window opening and send the data to the control system 35 for dynamic adjustment and precise stopping.

[0062] In this technical solution, the integration of position sensor 36 allows for highly precise control of the window during opening and closing, which is crucial for ensuring user comfort and energy efficiency.

[0063] Purpose: Position sensor 36 can monitor the opening angle or position of the window in real time, ensuring that the window opens or closes according to the user's specific needs, providing precise control. Precise control prevents the window from being over-opened or over-closed, thus preventing damage to the window frame or endangering the user's safety. Based on changes in the external environment (such as temperature, wind speed, and light), the window opening degree is dynamically adjusted to help maintain a stable indoor temperature, thereby improving energy efficiency.

[0064] Workflow: Position sensor 36, typically a photoelectric sensor, magnetic sensor, or linear encoder, is installed in the chain 4 drive system and measures the real-time position of the window. Position sensor 36 continuously monitors the window's movement, converting each displacement into an electrical signal. When the window opens or closes, position sensor 36 collects position data in real time and sends this data to control system 35. Upon receiving the position data, control system 35 performs real-time comparison and calculation based on the preset target opening or closing position of the window. If the actual window position deviates from the target position, control system 35 adjusts the drive command to ensure the window moves to the predetermined position or stops upon reaching the target position. Control system 35 can also adjust the target position based on data from external environmental sensors (such as temperature and wind sensors) to optimize the indoor environment. After window adjustment, control system 35 feeds back the final window position status to the user interface, such as a smart home application or central control panel 6. Users can check the real-time status of the window or adjust the degree of window opening through these interfaces. By integrating position sensor 36, the chain-type electric window opener achieves high precision and automation in window operation, providing a safe, convenient, and energy-efficient user experience. The application of this technology not only improves living comfort, but also helps reduce energy consumption by maintaining the stability of the indoor environment.

[0065] Example 3:

[0066] This embodiment provides a chain-type electric window opener, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] like Figure 5 As shown, in this embodiment, the optimized chain 4 includes a self-lubricating system 9 for applying lubricating oil to the chain 4.

[0068] In this technical solution, the design of the self-lubricating system 9 enables the chain 4 to be automatically lubricated during movement, thereby reducing friction and wear, which is crucial for improving the durability of mechanical components and reducing maintenance requirements.

[0069] Objective: The self-lubricating system 9 significantly reduces friction on the chain 4 during movement, which helps reduce wear and extend the service life of the chain 4 and related mechanical components. Because the chain 4 is self-lubricating, the need for regular lubrication is reduced, thereby lowering maintenance costs and workload. Reduced friction not only extends component life but also improves the operating efficiency and reliability of the window opener, ensuring smooth opening and closing of the window.

[0070] Workflow: The self-lubricating system 9 typically includes lubricating materials, such as lubricating oil or a specially formulated lubricating composite material, which are embedded or coated on key parts of the chain 4. The lubricating material may be designed to be gradually released with the movement of the chain 4, ensuring continuous lubrication. During the movement of the chain 4, the lubricating material is automatically and evenly released to all parts of the chain 4 through the micro-movements of the chain 4. The released lubricating material reduces direct metal-to-metal friction between the chain 4 and the drive gear and other contacting components. Advanced self-lubricating systems 9 may include sensors to monitor the lubrication status and performance of the chain 4. The control system 35 can adjust the amount of lubricating oil released based on sensor feedback to adapt to different operating conditions and environmental changes. Although the self-lubricating system 9 greatly reduces maintenance requirements, it is still necessary to periodically check the lubrication status and function of the system to ensure proper operation. The integration of the self-lubricating system 9 makes the chain-driven electric window opener more efficient, reliable, and economical in use. By automatically adjusting the lubrication status, this system not only improves the smoothness of window operation but also reduces the risk of mechanical failure due to wear, extending the overall lifespan of the equipment.

[0071] like Figure 5 As shown, in this embodiment, the optimized control system 35 further includes: a current detection module 353, used to detect the torque of the motor 31 during operation, and to convert the detected information and send it to the control unit 8. The control unit 8 controls the operating state of the motor 31 according to the information detected by the current detection module 353.

[0072] When the torque signal detected by the current detection module 353 is greater than a preset threshold, the control unit 8 shuts down the motor 31.

[0073] like Figure 5 As shown, in this embodiment, the optimized control system 35 further includes an alarm module 354, which is electrically connected to the control unit 8. When the torque signal detected by the current detection module 353 is greater than a preset threshold, the control unit 8 activates the alarm module 354 to make it emit an alarm sound.

[0074] In this technical solution, the current detection module 353 automatically cuts off the power supply when it detects abnormal operation or equipment failure, and sends an alarm to a preset mobile device or alarm module 354 via the wireless communication module 62. Rapidly cutting off the power supply in abnormal situations prevents potential safety accidents, such as damage caused by mechanical failure or accidental window closure. Immediately sending an alarm to the user or monitoring system via the wireless communication module 62 ensures that relevant personnel can respond quickly in the event of a failure or abnormal operation. Automatically stopping operation upon detecting a fault helps prevent the problem from escalating and protects the equipment from further damage.

[0075] Workflow: The control system 35 incorporates built-in sensors and algorithms to monitor the window opener's operational status in real time, including but not limited to parameters such as motor 31 current, voltage, opening speed, and force. When these parameters exceed the normal operating range, the system determines it as abnormal operation or malfunction. Once an abnormality or malfunction is detected, the control system 35 immediately cuts off the power supply to the motor 31, stopping the window operation to prevent further physical damage or equipment failure. Simultaneously, the control system 35 sends alarm information to preset mobile devices or alarm modules 354 via a built-in wireless communication module 62 (such as Wi-Fi, Bluetooth, or mobile network). Alarm information typically includes key information such as the fault type, occurrence time, and equipment location for rapid diagnosis and response. Users and administrators can preset alarm receiving devices, set alarm conditions, and view equipment status and historical alarm records through a mobile application or network interface 352. This not only provides operational convenience but also enhances the flexibility and effectiveness of safety management. This safety feature significantly improves the safety and reliability of the chain-type electric window opener, enabling timely interruption of operation and notification of maintenance personnel in the event of an abnormality or malfunction. This not only protects user safety but also reduces potential equipment damage.

[0076] Example 4:

[0077] This embodiment provides a chain-type electric window opener, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0078] like Figure 1 As shown, in this embodiment, the optimized window opener housing 1 is provided with two brushes 10 on the outside of the housing 1, which are located on both sides of the opening of the window opener housing 1, and are used to clean the surface of the extended or retracted chain 4.

[0079] In this technical solution, the main function of the brush 10 is to clean the extended or retracted chain 4.

[0080] The purpose is to keep chain 4 clean by removing dust and impurities, reducing wear and extending its service life. A clean chain 4 moves more smoothly, reducing jamming or resistance during operation and improving the efficiency of the window opener. Regular cleaning prevents dust and small particles from entering the machine's interior, thus avoiding damage to internal parts.

[0081] Workflow: Each brush 10 is installed on both sides of the opening in the window opener housing 1, precisely aligned with the movement trajectory of the chain 4. When the chain 4 extends or retracts, the brush 10 contacts the surface of the chain 4, achieving a physical cleaning effect. During the operation of the window opener, whether opening or closing the window, the chain 4 passes over the brushes 10 on both sides. The bristles of the brush 10 are long enough and of moderate hardness to effectively scrape off dust, dirt, or other particles adhering to the chain 4. The cleaning process is automatic and does not require manual operation by the user, ensuring that the chain 4 remains clean with each movement. Through continuous cleaning, the brush 10 not only protects the chain 4 but also indirectly protects other mechanical components inside the window opener, preventing malfunctions or performance degradation caused by the accumulation of contaminants. The addition of the brush 10 is an important feature in the design of the chain-driven electric window opener. Through a simple and effective physical cleaning mechanism, it ensures that the chain 4 remains clean during extension and retraction, thereby improving the reliability and efficiency of the entire system. This not only simplifies maintenance but also extends the service life of the equipment, making it key to efficient operation.

[0082] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the optimized electric drive unit 3 further includes a power line 33 and a reducer 34. The power line 33 is connected to the window opener housing 1 and electrically connected to the motor control board 32. The reducer 34 is disposed on the output shaft of the motor 31. The motor 31 changes its speed through the reducer 34 and transmits it to the chain 4.

[0083] In this technical solution, the reducer 34 is mounted on the output shaft of the motor 31 to increase torque and slow down speed, thereby controlling the movement of the chain 4 more precisely. One end of the chain 4 is connected to the output end of the reducer 34, and the other end is connected to the window via an adjustable connector 41. When the motor 31 is running, the reducer 34 transmits power to the chain 4, realizing the opening or closing action of the window.

[0084] Workflow: The user issues a command to open or close the window via a touchscreen or remote control. The control system 35 receives the command, processes the signal, and drives the electric drive unit 3 to operate the chain 4 through the motor 31 and reducer 34 to achieve precise opening or closing of the window. The reducer 34 (which drives a large gear through a small gear, which in turn drives a small gear, which in turn drives a sprocket) transmits the force generated in this process to the chain 4. Finally, the chain 4 extends or retracts to achieve the opening and closing action of the window. The reduction speed transmitted to the chain 4 is slowed down by the reducer 34, making the window opening operation more stable.
