Technical Field

[0001] This invention relates to the field of wearable device technology, specifically to an intelligent legal assistance wearable terminal. Background Technology

[0002] In legal practice, law enforcement, and dispute mediation, reliable on-site audio and video recording equipment is needed for evidence preservation. Simultaneously, law enforcement officers and lawyers often need to free their hands to work efficiently. Existing wearable recording devices suffer from several problems: limited functionality, low integration, unstable wear, inconvenient interaction, and insufficient security. Some devices only have basic recording functions, lacking crucial features such as biometric monitoring and emergency evidence preservation; some devices have unreasonable designs, resulting in poor wearing comfort and easy dislodgement; some devices have unclear status indicators, making it difficult for users to quickly determine the device's operating status; and some devices lack effective security mechanisms, posing risks of data leakage and misoperation, failing to meet the high requirements for reliability, security, and integration in legal support scenarios.

[0003] To address the shortcomings of the existing technologies, this invention proposes an intelligent legal assistance wearable terminal. By optimizing the structural design, integrating multiple functions, and improving the interaction logic, it solves the defects of existing devices and meets the actual use needs of legal evidence collection and related scenarios. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent legal assistance wearable terminal that enables high-definition audio and video acquisition, clear device status indication, biometric parameter monitoring, safe and stable wearing, and convenient interaction. In particular, it enhances the reliability and security in emergency evidence preservation scenarios, and provides efficient and reliable device support for legal assistance-related work.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: an intelligent legal assistance wearable terminal, including a shell, a camera, indicator lights, microphones, a control motherboard and a sensor group; the camera is disposed on the front side of the shell, the indicator lights are arranged around the camera and indicate different states by switching different colors, several microphones are provided on the shell, the control motherboard is disposed inside the shell, and the sensor group is disposed on the rear side of the shell for detecting heart rate, blood oxygen and emotional stress.

[0006] Furthermore, the outer shell includes a front shell, a middle frame, and a rear shell. The camera and indicator light are located on the front shell, the middle frame connects the front shell and the rear shell, and the sensor group is located on the inner side of the rear shell. The front shell is made of glass, preferably high-strength glass or sapphire glass, to ensure light transmission while providing good scratch and impact resistance. The middle frame is made of aluminum alloy, preferably aerospace-grade aluminum alloy, which combines structural strength and heat dissipation performance. The rear shell is made of ceramic or polymer composite material, which has skin-friendly properties and ensures wearing comfort.

[0007] Furthermore, the indicator light uses a ring-shaped light strip arranged around the camera, which can display colors such as blue, red, green, or yellow. Different colors and flashing modes correspond to different device operating states, specifically including: a blue breathing state indicates that the device is in standby mode and AI is listening; a solid red state indicates that audio and video recording is in progress; a solid green state indicates that the device has sufficient power and is operating normally; a fast red flashing state indicates that the emergency evidence storage mode is activated and data is being uploaded to the blockchain; and a flashing yellow state indicates that the device is malfunctioning, such as insufficient storage space or network disconnection.

[0008] Furthermore, the microphone is equipped with four high-sensitivity MEMS microphones, which are evenly distributed in a ring outside the light strip on the front side of the housing to achieve 360° omnidirectional sound pickup, beamforming noise reduction and sound source localization functions, ensuring clear audio acquisition in complex environments.

[0009] Furthermore, a multi-function button is provided on the mid-frame, which is electrically connected to the control motherboard. This multi-function button features a concentric metal texture design and integrates a capacitive fingerprint recognition module in the center. Its interaction logic includes: a short press to power on / off / wake up / sleep; a double press to quickly start / stop standard recording; and a 2-second long press to trigger an "emergency evidence storage mode," in which the device is forced to record and upload data to the blockchain in real time. Fingerprint verification is used for device unlocking and confirming high-risk operations, ensuring both physical and data security of the device.

[0010] Furthermore, the lower end of the housing is equipped with a charging port and docking station contacts. The charging port uses a USB-C interface for high-speed data transmission and wired fast charging; the docking station contacts are a set of magnetic PogoPin contacts for connecting to a dedicated docking station, enabling fast charging, data synchronization, and fixed-position shooting functions.

[0011] Furthermore, the sensor array includes a PPG biosensor, a skin conductance sensor, and an infrared sensor. The PPG biosensor is used to monitor heart rate and blood oxygen saturation; the skin conductance sensor is used to monitor stress levels and mood fluctuations; and the infrared sensor assists in wear detection and ambient light perception, improving the safety and intelligence of the device.

[0012] Furthermore, the rear shell of the outer casing is equipped with neodymium magnets, specifically a set of neodymium iron boron strong magnets, to ensure that the device can be stably attached to clothing.

[0013] Furthermore, the control motherboard adopts a highly integrated modular design, with a low-power AIoT chip at its core, surrounded by closely arranged storage, communication, and power management modules to ensure low-power operation and stable performance. The device also features an optimized heat dissipation design, with the metal mid-frame serving as the primary heat sink. Thermal grease is used internally to conduct heat from the chip to the mid-frame and rear shell, ensuring stable operation over extended periods. In terms of antenna design, 4G / 5G, Wi-Fi, and Bluetooth antennas are integrated into the non-metallic parts of the mid-frame, utilizing the metal mid-frame itself as part of the antenna to optimize signal transmission. The device achieves an IP67 waterproof and dustproof rating through sealing rings, waterproof membranes, and nano-coatings, adapting to complex operating environments.

[0014] The advantages of this invention compared to the prior art are: This invention integrates multiple functions such as high-definition audio and video acquisition, device status ring indication, biometric parameter monitoring, emergency evidence storage, and safe wearing, meeting the core needs of legal assistance scenarios in one stop, without the need to carry multiple additional devices; The ring light strip of the present invention intuitively indicates the operating status of the device through different colors and flashing patterns, allowing users to quickly determine whether the device is in standby, recording, emergency evidence storage, or abnormal status, thereby improving usage efficiency. This invention enables high-speed data transmission, fast charging, and connection to a dedicated docking station via a USB-C interface and magnetic PogoPin expansion contacts, expanding the device's usage scenarios and improving its applicability.

[0020] The following is a detailed description of an intelligent legal assistance wearable terminal according to the present invention, with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1-2 This invention will be described in detail below.

[0022] This embodiment provides a smart legal assistance wearable terminal, featuring a compact circular badge / brooch design, approximately 45mm in diameter and 10mm thick, exuding both professionalism and technological sophistication. The device casing 1 employs a classic sandwich structure, comprising a front shell, a middle frame, and a back shell, with the structural and material configurations of each part as follows: The front cover is made of sapphire glass, which has excellent light transmission, scratch resistance and impact resistance. The camera 2 is fixedly installed in the center of its inner side, and a ring light strip (indicator light 3) is arranged around the camera 2. Four microphone openings are evenly distributed in a ring on the outer side of the ring light strip. The mid-frame is made of aerospace-grade aluminum alloy, which serves as the main support structure of the device and also undertakes heat dissipation. The right side of the mid-frame has a multi-function button 7. The non-metallic part of the mid-frame integrates 4G / 5G, Wi-Fi, and Bluetooth antennas, and uses the metal mid-frame itself as part of the antenna to optimize signal transmission. The back cover is made of skin-friendly ceramic material. The sensor group 6 is fixedly installed on the inside, and a set of neodymium iron boron strong magnets are provided on the outside. A movable physical safety lock can be added as needed. A micro-hole array can also be designed around the sensor group 6 on the back cover for internal heat dissipation.

[0023] Camera 2 is a custom-designed 200° ultra-wide-angle, low-distortion high-definition camera, installed in the center of the front shell, ensuring that the first-person view can cover most scenes, enabling high-definition video capture and meeting the requirements for video quality and perspective in legal evidence collection scenarios.

[0024] Indicator light 3 uses an RGB multi-color LED ring arranged around camera 2 and is electrically connected to the control motherboard 5. It indicates the device's operating status through different colors and flashing modes. The specific functional logic is as follows: Blue Breath: The device is in standby mode and AI is monitoring. At this time, the device is in a low-power state and can respond to operation commands at any time. Solid red: Recording is in progress. At this time, camera 2 and microphone 4 work synchronously to collect on-site audio and video data. Solid green light indicates that the device has sufficient power, is operating normally, and has no abnormal malfunctions. Red Flash: Emergency evidence storage mode activated, data is being uploaded to the blockchain. At this time, the device will forcibly start the audio and video recording function, regardless of the current state, and upload the collected data to the blockchain node in real time to ensure that the evidence is tamper-proof. Yellow flashing: Device malfunction, including insufficient storage space, network disconnection, sensor failure, etc. In this case, the device will emit a warning sound and the yellow light strip will flash to remind the user to deal with it in time.

[0025] Microphone 4 uses four high-sensitivity MEMS microphones 4, which are evenly distributed in a ring outside the ring light strip and electrically connected to the control motherboard 5 to achieve 360° omnidirectional sound pickup. At the same time, it uses beamforming noise reduction technology to filter ambient noise, improve the clarity of audio acquisition, and has a sound source localization function, which can accurately identify the direction of the sound source and provide more comprehensive audio information for legal evidence collection.

[0026] The multi-function button 7 is located on the right side of the middle frame, featuring a concentric circle textured metal design with a non-slip and wear-resistant surface. In high-end models, a capacitive fingerprint recognition module can be integrated into the center of the multi-function button 7, which is electrically connected to the control motherboard 5. Its interaction logic is as follows: A short press: triggers power-on when the device is powered off; triggers wake-up / sleep switching when the device is in power-on standby / sleep mode. Double-press: Quickly start / stop standard recording without entering the system interface, improving recording startup efficiency; Press and hold for 2 seconds: Ignore any status and trigger "Emergency Evidence Storage Mode". At this time, the device will forcibly start camera 2 and microphone 4 to record audio and video, and immediately connect to the network to upload the data to the blockchain in real time. At the same time, the red light strip will flash rapidly to remind people around that the device is in emergency evidence storage mode. Fingerprint verification: Fingerprint verification is required after the device is powered on to unlock the operation interface; fingerprint verification is required again when performing high-risk operations such as formatting, deleting recordings, or turning off data uplink, to ensure that only authorized personnel can operate the device and prevent accidental deletion or leakage of data.

[0027] The charging port 8 and the docking station contact 9 are located at the bottom of the housing 1. The charging port 8 uses a USB-C interface, which supports USB 3.0 high-speed data transmission and 20W wired fast charging. The docking station contact 9 is a set of 4-pin magnetic PogoPin contacts with anti-misinsertion function. After being connected to a dedicated docking station, it can realize fast charging, data synchronization and fixed position shooting functions. For example, after connecting to a car mount, the device can be fixed in the car to realize audio and video recording during driving.

[0028] Sensor group 6 is installed inside the rear housing and electrically connected to the control motherboard 5. It includes a PPG biosensor, a skin conductance sensor, and an infrared sensor. The functions of each sensor are as follows: The PPG biosensor uses photoelectric plethysmography technology to monitor the user's heart rate and blood oxygen saturation in real time. The data is displayed on the device's accompanying APP in real time, making it convenient for users to understand their own physiological status. Skin conductance sensor: By detecting changes in the resistance of the user's skin surface, it can determine the user's stress level and emotional fluctuations. When the device detects that the user is in a high stress state, the accompanying APP will issue a stress warning. Infrared sensor: It has dual functions. First, it is wear detection. When the device leaves the user's skin, the device will automatically lock the screen to prevent unauthorized operation. Second, it is ambient light sensing. It will automatically adjust the exposure parameters of camera 2 and the brightness of the ring light strip according to the ambient light intensity to ensure clear video capture and obvious light strip indication in strong or low light environments.

[0029] The outer back cover is equipped with a set of 3 neodymium magnets to ensure that the device can be firmly attached to clothing and will not fall off even during rapid movement or limb activity. At the same time, an additional movable physical safety lock can be added to the outer back cover. After the device is attached to clothing, the lock can be moved to the locked position. The buckle structure of the lock engages with the clothing fibers to further prevent the device from falling off accidentally and improve wearing safety.

[0030] The control motherboard 5 adopts a highly integrated modular design. The core chip is a low-power AIoT chip with a main frequency of 1.2GHz, paired with 2GB LPDDR4 memory and 32GB eMMC flash memory, which supports low-power operation of the device and large-scale audio and video data storage. The motherboard also integrates a power management module and a communication module to ensure stable communication and battery life of the device. The metal frame serves as the main heat sink. Thermal grease is applied to the surface of the chip on the control motherboard 5 to conduct the heat generated by the chip during operation to the mid-frame and the back cover. The heat is then dissipated to the outside through the heat dissipation grille on the back cover, ensuring that the core temperature does not exceed 45°C during long-term operation and avoiding high temperature affecting the performance of the device. The device is designed with an IP67 waterproof and dustproof rating. Silicone sealing rings are provided at the joints between the front shell and the middle frame, and between the middle frame and the rear shell. Waterproof membranes are provided at the microphone 4 and the charging port 8. The surface of the control motherboard 5 is coated with a nano waterproof coating, which can effectively prevent dust and water from entering the device and ensure the reliability of the device in complex environments.

[0031] The specific implementation process of the intelligent legal assistance wearable terminal of the present invention is as follows: Press the multi-function button 7 briefly to power on the device. The ring light will then flash blue. At this point, you will need to verify your fingerprint using the fingerprint recognition module. Once the verification is successful, the device will unlock and enter standby mode, with the ring light remaining blue. In standby mode, press the multi-function button 7 twice to activate the camera 2 and microphone 4 to start recording audio and video, and the ring light will be solid red; press the multi-function button 7 twice again to stop recording, the data will be automatically stored in the internal flash memory, the device will return to standby mode, and the ring light will return to blue breathing mode. In any state, pressing and holding the multi-function button for 72 seconds will immediately trigger the emergency evidence storage mode, forcibly starting camera 2 and microphone 4 to record audio and video, and the ring light will flash red rapidly. At the same time, the real-time collected data will be uploaded to the blockchain node via 4G / 5G or Wi-Fi network to ensure that the data cannot be tampered with. The emergency evidence storage mode can only be stopped by fingerprint verification. After stopping, the data will be stored in the internal flash memory and the blockchain, and the device will return to standby mode. When the device is worn, the infrared sensor detects that the device is in contact with the skin and automatically activates the PPG biosensor and skin conductance sensor to monitor heart rate, blood oxygen saturation and pressure levels in real time. The data is synchronously transmitted to the accompanying APP, which the user can view. If the device is removed from the skin, the infrared sensor detects it and the device automatically locks the screen and stops monitoring the bio-parameters. When the device experiences abnormalities such as insufficient storage space, network disconnection, or sensor failure, the ring light will flash yellow, and the device will emit a buzzer to remind the user to handle the situation in a timely manner. The device can be charged via USB-C charging port 8. During charging, the ring light strip will flash green in a breathing pattern. Once fully charged, the ring light strip will remain solid green. When connected to a dedicated docking station, fast charging, data synchronization, and fixed-position shooting can be achieved via docking station contacts 9. At this time, the ring light strip will flash green twice to indicate a successful connection.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
