Description

Technical Field

[0001] This utility model relates to the field of television technology, specifically to a smart reminder device for television viewing distance. Background Technology

[0002] With the widespread use of electronic devices, children are spending increasingly more time watching television or electronic screens. However, due to children's lack of self-control, they easily get too close to screens, which has become a major reason for the high rate of myopia among children. According to relevant data, the myopia rate among children and adolescents in my country has reached over 50%, and it is showing a trend towards younger ages, becoming a significant public health issue affecting children's healthy growth. Currently, the main solutions on the market for addressing the problem of children watching screens too closely include the following:

[0003] Software reminders: Reminders pop up through TV software, but this method is easily ignored or turned off by children, so its effectiveness is limited and it cannot truly play an intervention role.

[0004] Physical timers require parents to manually set viewing time or distance, and cannot detect the distance between the child and the screen in real time, making it difficult to solve the problem of children gradually moving closer to the screen during viewing.

[0005] Signal-cutting devices: These devices directly cut off the video signal or turn off the screen when they detect that the user is too close. This method provides a very poor user experience, causing abrupt interruptions to video and sound, which can easily provoke strong resistance and defiance from children. Furthermore, the interruption requires waiting for a restart, a choppy process that severely impacts the viewing experience and makes gradual intervention impossible.

[0006] The aforementioned existing technologies all have significant drawbacks and cannot effectively solve the problem of children watching screens at excessively close distances. Software reminders have limited effectiveness, physical timers cannot intervene in real time, and signal cut-off devices are unacceptable due to poor user experience. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a smart reminder device for TV viewing distance. This device can achieve gentle, immediate and effective intervention to effectively solve the problem of myopia caused by children watching TV too closely.

[0008] The technical solution adopted by this utility model is: a smart reminder device for television viewing distance, including a detection module, a control module, and an adjustment module; the detection module includes a distance sensor module for detecting the distance between the television screen and the viewer; the control module is signal-connected to the distance detection sensor, and the control module can set the limit distance between the television screen and the viewer, and the control module is also connected to a power supply module; the adjustment module includes an electrically controlled dimming film that is signal-connected to the control module and installed in front of the television screen. When the distance between the viewer and the television screen is less than the limit distance set by the control module, the transparency of the electrically controlled dimming film gradually decreases to block the content displayed on the television screen; conversely, the electrically controlled dimming film remains transparent.

[0009] In this technical solution, the detection module uses a distance sensor module to detect the distance between the viewer and the TV screen and transmits the detection data to the control module in real time. The control module can set the viewing distance. Once the distance is less than the set limit, it controls the operation of the electronically controlled dimming film to reduce its transparency, thereby prompting the viewer to adjust the viewing distance. When the viewing distance is greater than the set distance, the dimming film adjusts to a transparent state, and the TV can be watched normally. The reminder is given by triggering the dimming film, making the intervention process natural and smooth. There is no need to cut off or turn off the TV signal. The reminder method is more gentle and maintains the continuity of the viewing experience.

[0010] Preferably, the distance sensor module is detachably installed on the front side of the television.

[0011] Preferably, the detection module further includes a face recognition module for identifying specific audience members, and the control module is signal-connected to the face recognition module for setting corresponding distance parameters for specific audience members identified by the face recognition module.

[0012] Preferably, the face recognition module includes a high-precision camera integrated with the distance sensor module and an image processing module. The high-precision camera transmits the captured user face image to the image processing module, which processes the captured image and feeds back the processed information to the control module.

[0013] Preferably, the control module includes a controller body, which is connected to a wireless control module.

[0014] Preferably, the surface of the electronically controlled dimming film is coated with a protective film.

[0015] Preferably, the edge of the electronically controlled dimming film is provided with a mounting frame, and the mounting frame is detachably connected to the front edge of the television.

[0016] The beneficial effects of this invention are as follows: This invention uses an electronically controlled dimming film to gradually reduce its transparency for alerts, avoiding the sudden interruption of picture and sound caused by traditional signal cut-off devices. This prevents children from reacting strongly or resisting, and the intervention process is natural and smooth, maintaining the continuity of the viewing experience. During use, the distance between the viewer and the television screen is detected in real time. Once the distance is less than the set limit, the dimming film is triggered immediately, achieving immediate and continuous intervention without manual operation, effectively solving the problem of excessively close viewing distances. Furthermore, this device can identify specific viewers and set personalized safe viewing distance parameters for them, making the protection more scientific and targeted, meeting the vision protection needs of different children; it has high practical value.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0023] like Figure 1 and Figure 2As shown in the illustration, this utility model provides a smart TV viewing distance reminder device, mainly composed of a detection module, a control module, and an adjustment module. These three modules interact via wired or wireless signals. The detection module is installed on the front of the TV to collect distance and facial information in real time. The control module can be integrated into the TV or fixed as an independent module on the outside of the TV, such as on the back. The adjustment module fits snugly against the TV screen surface, perfectly matching the screen size, and adjusts the transparency of the displayed content. The device also includes a power supply module to power the entire unit.

[0024] Specifically, the detection module includes a distance sensor module 100 and a face recognition module 300, both integrated into the same housing to form an integrated detection unit, which is easy to install and remove. The detection module is installed through a detachable structure, using a magnetic base to install on the front of the TV body 800, or fixed to the reserved holes on the frame by clips. When removing it, you only need to press the elastic end of the clip or directly peel off the magnetic base, without damaging the appearance of the TV. The distance sensor module 100 is used to detect the distance between the television screen and the viewer. It can be an infrared distance sensor, an ultrasonic sensor, or a millimeter-wave radar sensor. It should be noted that for some larger televisions, multiple distance sensor modules can be arranged at intervals in front of the television to broaden the distance detection range and improve the accuracy of the viewer distance detection. The face recognition module 300 includes a high-precision camera and an image processing module. The camera uses a high-definition lens to clearly capture face images within the viewing range. The image processing module uses an embedded chip with a built-in face recognition algorithm, which can quickly extract facial feature points and distinguish viewers of different ages and identities. During operation, the high-precision camera transmits the captured face images to the image processing module in real time. After feature extraction and comparison, the processing module feeds back the recognition results (such as "child A" and "adult B") to the control module, providing a basis for setting personalized distance parameters.

[0025] The control module, including the controller body 400, is connected to the distance detection sensor signal and is connected to the wireless control module 500. The controller body 400 has a built-in storage unit that can store personalized distance parameters for multiple viewers. During operation, it can simultaneously receive signals from the distance sensor module 100 and the face recognition module 300, and output control commands to the adjustment module. The wireless control module 500 integrates Bluetooth and WiFi dual-mode modules, supporting wireless connection with a mobile app or TV remote control. Users can set and modify the maximum distance parameters and view the current viewing distance and device operating status through the app or remote control. The wireless control module 500 is compatible with corresponding software systems, and the software interface includes multiple functional modules such as distance settings, face management, and device control, allowing for remote control of the device's start and stop, suitable for various home scenarios.

[0026] For ease of installation, in this embodiment, the edge of the electronically controlled dimming film 200 is also provided with a mounting frame 700. The mounting frame 700 is used for detachable connection to the edge of the TV screen. The edge of the mounting frame 700 is installed through structures such as slots and fixing buckles. The detachable installation improves the convenience of installation and removal. At the same time, the detection module can also be fixed to the mounting frame, resulting in a higher degree of integration. The detection module can also be installed on the mounting frame 700 through magnetic or snap-fit ​​structures. In some embodiments, the mounting frame 700 can be omitted. During installation, the electronically controlled dimming film 200 is adhered to the surface of the TV screen with optical adhesive to avoid reflection and glare. The surface of the electronically controlled dimming film 200 is covered with a protective film made of PET material, 0.1mm thick, which has anti-scratch, anti-fingerprint, and anti-blue light functions, effectively protecting the dimming film from wear and tear, while reducing the harmful effects of blue light from the screen on the eyes. It also has a buffering and anti-impact function, preventing the edge of the dimming film from being damaged by force, and filling the gap between the dimming film and the TV frame, improving the overall aesthetics.

[0027] In this embodiment, the adjustment module includes an electrically controlled dimming film 200 that is signal-connected to the control module and installed in front of the television screen. When the distance between the viewer and the television screen is less than the limit distance set by the control module, the transparency of the electrically controlled dimming film 200 gradually decreases to block the content displayed on the television screen; conversely, the electrically controlled dimming film 200 remains transparent. In practical applications, the electrically controlled dimming film 200 can be a PDLC liquid crystal dimming film with a thickness of 0.2mm, a transmittance adjustment range of 0-90%, and a response time ≤0.3 seconds. It can achieve a smooth and gradual change in transparency according to control commands, rather than a sudden change, to avoid affecting the viewing experience.

[0028] Before using this device, the facial information of a specific viewer, such as a child in the home, should be entered using compatible software. At the same time, the minimum viewing distance for that viewer should be entered. Other viewers who need to be restricted can also be entered as needed.

[0029] In use, the mounting frame 700 is fastened to the front of the TV body 800, positioning the electronically controlled dimming film directly in front of the screen. Alternatively, the electronically controlled dimming film can be directly attached to the screen of the TV body 800 using optical adhesive. When the TV is turned on, the adjustment device is powered on, and the distance sensor module begins to detect the distance between the viewer and the screen in real time, with a detection frequency of 10 times / second. The face recognition module simultaneously collects facial images of people in the viewing area for identity recognition. If a specific viewer (such as a child) is identified, the control module calls the corresponding limit distance parameter (1.5 meters). When the detected actual distance (e.g., 1.2 meters) is less than the limit distance, the control module outputs a voltage signal, gradually reducing the transparency of the electronically controlled dimming film until it drops to 30%, partially obscuring the screen display content and prompting the viewer to adjust their distance. This process does not affect normal TV playback. When the viewer adjusts their distance to above the limit distance (e.g., 1.6 meters), the control module controls the transparency of the electronically controlled dimming film to gradually return to normal viewing transparency, thus restoring normal viewing. If multiple children are detected in the detection area, the control module will make a judgment based on the strictest limit distance parameter (such as the minimum of 1.5 meters) to ensure that the viewing distance of all viewers meets the health standards.

[0030] In addition, during daily use, the device administrator can manually adjust the transparency of the electronically controlled dimming film or temporarily turn off the reminder function via a mobile app or remote control to meet special viewing needs.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
