Description

Technical Field

[0001] This utility model relates to a book clip device. Background Technology

[0002] Book clips, also known as page binders or reading clips, are typically made of metal or plastic and are used solely to secure and organize book pages, preventing them from flipping back during reading. They are simple in structure and inexpensive, but their function is singular, making them purely mechanical stationery. With the rapid popularization of new reading aids such as e-readers and smart pens, existing book clips are increasingly unable to meet people's diverse needs for reading experience and health protection. Medical research shows that if the ambient light level during reading is consistently below 300 lux or above 500 lux, it will significantly increase the burden on eye accommodation, leading to eye strain, dry eye syndrome, and even increased myopia. However, most readers lack real-time, intuitive means of judging light intensity and often rely on subjective feelings to decide whether to turn the lights on or off or adjust the brightness, which is highly arbitrary and lagging.

[0003] Currently, there are two main types of illuminance measurement devices on the market: The first type is a stand-alone illuminance meter: Although it has high measurement accuracy, it is large and expensive, and is usually used in laboratories or professional lighting projects, and is not suitable for daily carrying. The second type is a mobile app that works with the phone's light sensor: Although convenient, the measurement accuracy is greatly affected by the phone model, sensor position and screen brightness, and it requires unlocking the phone and launching the app, which is cumbersome and makes it difficult to form a continuous and imperceptible light environment monitoring system.

[0004] In summary, existing book clips cannot monitor and alert users to ambient light intensity in real time, while professional lux meters or mobile apps suffer from insufficient portability, ease of use, and real-time performance. Therefore, there is an urgent need for a smart book clip that is compact, inexpensive, and capable of sensing ambient light intensity in real time and providing intuitive color alerts to users, in order to fill the market gap and effectively protect readers' eyesight. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing book clips cannot monitor and indicate ambient light intensity in real time, and to propose an intelligent ambient light sensing book clip.

[0006] The present invention relates to an intelligent ambient light sensing book clip, which includes a book clip body;

[0007] It also includes dimmable LEDs, an MCU, and a light sensor;

[0008] The light sensor is used to detect ambient light intensity in real time, and the light intensity signal output terminal of the light sensor is connected to the light intensity signal input terminal of the MCU.

[0009] The MCU compares the received light intensity signal with a preset first light intensity threshold and a preset second light intensity threshold. If the first light intensity threshold is less than the second light intensity threshold, the MCU emits a blue light band signal when the light intensity signal is less than the first light intensity threshold; it emits a green light band signal when the light intensity signal is greater than the second light intensity threshold; otherwise, the MCU emits a red light band signal.

[0010] The dimmable LED is used to receive the band signals emitted by the MCU and display them accordingly.

[0011] Furthermore, the first light intensity threshold is 300 lux.

[0012] Furthermore, the second light intensity threshold is 500 lux.

[0013] Furthermore, the book clip body includes an upper clip plate, a lower clip plate, a pin, and a torsion spring; the upper clip plate and the lower clip plate are pivotally connected by the pin; the torsion spring is sleeved on the pin.

[0014] Furthermore, the dimmable LED, MCU, and light sensor are all housed within the upper clamping plate;

[0015] A photosensitive hole is opened on the side wall of the clamping end of the upper clamping plate, and a photosensitive sensor is set at the photosensitive hole; a warning hole is opened on the top surface of the upper clamping plate, and the lamp body of the dimmable LED passes through the warning hole.

[0016] Furthermore, this also includes rechargeable batteries;

[0017] The rechargeable battery powers the dimmable LED, MCU, and light sensor respectively; and the rechargeable battery is located inside the upper clamping plate.

[0018] Furthermore, the clamping surface of the upper clamping plate is provided with a first columnar protrusion; the clamping surface of the lower clamping plate is provided with a second columnar protrusion.

[0019] The first columnar protrusion is positioned opposite to the second columnar protrusion.

[0020] Furthermore, the optical sensor is model TEMT6000.

[0021] Furthermore, the MCU is model ESP8266.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] By placing the dimmable LED, MCU, and light sensor inside the upper clamp, the light sensor can monitor the reading environment in real time. The three-segment color mark of the dimmable LED (blue-green-red) instantly provides feedback on the light intensity range, allowing users to determine whether the environment is suitable for reading without additional operation, significantly reducing the risk of eye fatigue. By combining ambient light perception with the depth of the book clip structure, the light intensity of the reading environment is indicated in real time through color changes, while also taking advantage of low power consumption and miniaturization.

[0029] Specific Implementation Method 1: Combination Figures 1 to 5 This embodiment describes an intelligent ambient light sensing book clip, which includes a book clip body.

[0030] It also includes a dimmable LED5, an MCU6, and a light sensor7;

[0031] The light sensor 7 is used to detect the ambient light intensity in real time, and the light intensity signal output terminal of the light sensor 7 is connected to the light intensity signal input terminal of the MCU 6.

[0032] MCU6 is used to compare the received light intensity signal with a preset first light intensity threshold and a preset second light intensity threshold. If the first light intensity threshold is less than the second light intensity threshold, MCU6 emits a blue light band signal when the light intensity signal is less than the first light intensity threshold; emits a green light band signal when the light intensity signal is greater than the second light intensity threshold; otherwise, MCU6 emits a red light band signal.

[0033] The dimmable LED5 is used to receive the band signals emitted by the MCU6 and display them accordingly.

[0034] In this embodiment, the MCU's workflow is as follows: First, a power-on self-test is performed. After the dimmable LED5 flashes three times, it indicates that the MCU6 is in a normal state. At this time, the light sensor 7 detects the ambient light. Second, the MCU6 determines whether the light intensity signal is less than the first light intensity threshold. If so, the MCU6 sends a blue light band signal to the dimmable LED5, and the dimmable LED5 displays blue. Otherwise, the MCU6 determines whether the light intensity signal is greater than the second light intensity threshold. If so, the MCU6 sends a green light band signal to the dimmable LED5, and the dimmable LED5 displays green. If the light intensity signal is less than the second light intensity threshold, the MCU6 sends a green light band signal to the dimmable LED5, and the dimmable LED5 displays green. When the light intensity is between the first and second threshold values, the MCU6 emits a red light signal to the dimmable LED5, which then displays red. In other words, the intelligent ambient light sensor book clip indicates the ambient light intensity range through the color change of the dimmable LED5: when the light intensity signal is less than the first threshold, the dimmable LED5 displays blue, indicating that the ambient light is too dim for reading; when the light intensity signal is between the first and second thresholds, the dimmable LED5 displays green, indicating that the ambient light is suitable for reading; and when the light intensity signal is greater than the second threshold, the dimmable LED5 displays red, indicating that the ambient light is too strong for reading. By indicating the light intensity through color, it warns whether the ambient light is suitable for reading. The dimmable LED5 is an RGB adjustable LED, and its brightness and color can be adjusted in real time according to the ambient light intensity.

[0035] Specific Implementation Method Two: This implementation method further defines the intelligent ambient light sensing book clip described in Specific Implementation Method One. In this implementation method, the first light intensity threshold is 300 lux.

[0036] In this embodiment, the first light intensity threshold of 300 lux corresponds to the minimum illuminance for reading, ensuring the scientific accuracy and authority of the prompts.

[0037] Specific Implementation Method 3: This implementation method further defines the intelligent ambient light sensing book clip described in Specific Implementation Method 2. In this implementation method, the second light intensity threshold is 500 lux.

[0038] In this embodiment, the second light intensity threshold of 500 lux corresponds to the upper limit of comfort; and forms a unique "dual threshold three colors" correspondence with the first light intensity threshold of 300 lux, so that users do not need to memorize numbers, but only need to look at the colors.

[0039] Specific Implementation Method Four: This implementation method further defines the intelligent ambient light sensing book clip described in Specific Implementation Method One. In this implementation method, the book clip body includes an upper clamping plate 1, a lower clamping plate 2, a pin 3, and a torsion spring 4. The upper clamping plate 1 and the lower clamping plate 2 are pivotally connected by the pin 3. The torsion spring 4 is sleeved on the pin 3.

[0040] In this embodiment, the book clip body adopts a classic four-piece structure of "upper clip plate - lower clip plate - pin - torsion spring", which is completely consistent with the operation of ordinary book clips, and users can get started without learning; the clamping force of the torsion spring 4 increases linearly with the opening angle, so that thick books will not loosen and thin books will not deform, providing a uniform pre-tightening force basis for the columnar protrusions to engage in subsequent embodiments.

[0041] Specific Implementation Method 5: This implementation method further defines the intelligent ambient light sensing book clip described in Specific Implementation Method 4. In this implementation method, the dimmable LED 5, MCU 6 and light sensor 7 are all disposed in the upper clamping plate 1.

[0042] A photosensitive hole is opened on the side wall of the clamping end of the upper clamping plate 1, and a photosensitive sensor 7 is set at the photosensitive hole; a warning hole is opened on the top surface of the upper clamping plate 1, and the lamp body of the dimmable LED 5 passes through the warning hole.

[0043] In this embodiment, the upper clamping plate 1 and the lower clamping plate 2 are made of ABS plastic (lightweight and 3D printable); the upper clamping plate 1 has a light-transmitting part, which is made of acrylic light guide plate or open hole. Integrated hidden design: the photosensitive hole is located on the side wall of the clamping end to avoid being blocked by the hand; the warning hole is located on the top surface, and the dimmable LED5 lamp body is still below the upper surface of the upper clamping plate 1 after it protrudes, to prevent accidental bumps; both acrylic light guide plate and open hole can be selected to balance uniform light output and cost.

[0044] Specific Implementation Method Six: This implementation method further defines the intelligent ambient light sensing book clip described in Specific Implementation Method Four. In this implementation method, a rechargeable battery 8 is also included.

[0045] The rechargeable battery 8 supplies power to the dimmable LED 5, MCU 6 and light sensor 7 respectively; and the rechargeable battery 8 is disposed in the upper clamping plate 1.

[0046] In this embodiment, the rechargeable battery 8 uses a blade lithium battery + USB boost charging circuit, which increases the thickness of the book clip by less than 3mm, but in return, it provides a "rechargeable" experience, eliminating the hassle of replacing disposable button batteries and environmental issues.

[0047] Specific Implementation Method Seven: This implementation method further defines the intelligent ambient light sensing book clip described in Specific Implementation Method Four. In this implementation method, the clamping surface of the upper clamping plate 1 is provided with a first columnar protrusion 9; the clamping surface of the lower clamping plate 2 is provided with a second columnar protrusion 10.

[0048] The first columnar protrusion 9 and the second columnar protrusion 10 are arranged opposite to each other.

[0049] In this embodiment, the first columnar protrusion 9 and the second columnar protrusion 10 form a "tooth-like" engagement, which increases the local pressure on the page and avoids scratching the paper. When the book clip is used for thick books, the protrusions can be embedded in the spine groove, increasing the clamping force by more than 30%, ensuring that the book clip and internal electronic components do not shift or fall during page turning and moving.

[0050] Specific Implementation Method Eight: This implementation method further defines the intelligent ambient light sensing book clip described in Specific Implementation Method One. In this implementation method, the light sensor 7 is model TEMT6000.

[0051] In this embodiment, the light sensor 7 is a surface-mount ambient light sensor; the TEMT6000 surface-mount package is only 3 mm × 4 mm, which can be directly soldered to the MCU6, reducing the need for flexible wiring and lowering assembly complexity and failure rate. Embedding the surface-mount ambient light sensor (TEMT6000) inside the upper clamping plate 1, it directly faces the reading environment through the photosensitive hole, allowing for continuous and interference-free acquisition of the current desktop illuminance during reading, thus solving the problem of the book clip and illuminance meter being "independent and unable to be integrated".

[0052] Specific Implementation Method Nine: This implementation method further defines the intelligent ambient light sensing book clip described in Specific Implementation Method One. In this implementation method, the MCU6 is model ESP8266.

[0053] In this embodiment, the ESP8266 MCU integrates Wi-Fi functionality (which can be reserved for subsequent OTA upgrades or data uploads), and also has a built-in ADC that can directly read the 7 analog signals from the light sensor; furthermore, the small size of this MCU helps to reduce the overall size and weight of the smart ambient light sensor book clip.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
