Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and in particular to a flexible circuit fixing mechanism and fixing method for smart wearable devices. Background Technology

[0002] As a wearable device for detecting electrocardiogram (ECG) signals, an ECG vest typically includes the vest itself, contact electrodes, conductive fabric, a fixing device, and a controller. After the electrodes collect the ECG signal, it is transmitted to the controller via the conductive fabric. Currently, most ECG vests on the market use snaps to fix the conductive fabric to the controller. These snaps are prone to falling off after repeated use, resulting in a weak connection and insufficient reliability. Furthermore, the electrodes in existing ECG vests are mostly fixed connections, and some materials lack good water-resistant properties, making the vests difficult to wash. Long-term use can lead to bacterial growth, affecting hygiene and safety and the device's lifespan. In addition, the signal transmission and reception methods of existing ECG vests are relatively simple, lacking a supporting precise signal reception and processing system, which fails to meet users' needs for convenient and accurate acquisition and analysis of ECG signals. Therefore, improvements are needed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible circuit fixing mechanism and fixing method for smart wearable devices.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flexible circuit fixing mechanism for a smart wearable device includes a wearable garment and a mobile terminal. A mounting plate is detachably connected to one side of the wearable garment. A housing assembly is detachably connected to the mounting plate. A flexible circuit board and conductive foam are installed inside the housing assembly. The flexible circuit board is disposed between the conductive foam and the mounting plate. A conductive cloth is connected to one end of the conductive foam. The conductive cloth passes through the mounting plate and extends to one side of the mounting plate. The lower end of the wearable device is detachably connected to a controller, which is electrically connected to the wearable device. A second sub-adhesive is fixed to the upper end of the controller, and a second master adhesive is fixed to one end of the conductive fabric. Contact electrodes are installed on opposite sides of the conductive fabric and the second sub-adhesive, and the contact electrodes on the conductive fabric and the contact electrodes on the second sub-adhesive are in contact with each other.

[0005] Compared with existing technologies, the overall technical solution of this invention is reasonably designed, the conductive foam fixing method is easy to operate, the wearable device is comfortable to wear and convenient to use, the APP system has complete functions, and all parts work together to achieve accurate acquisition, stable transmission, efficient processing and convenient viewing of electrocardiogram signals. At the same time, it is easy to disassemble and install quickly, facilitates cleaning of wearable devices, and avoids damage to control components.

[0006] Preferably, the wearable device is fixed with a mounting base, a first master glue is installed on the mounting base, and a first sub-glue is fixed on the side of the mounting plate near the first master glue, the first sub-glue and the first master glue are connected; The mounting plate has multiple notches at equal intervals at one end near the wearable device, and multiple filter screens are provided through the mounting plate, with each filter screen corresponding to one of the multiple notches. The contact electrodes on the second sub-adhesive are connected to the controller.

[0007] Furthermore, the mounting base facilitates connection with the first masterbatch, and it adopts a detachable connection to facilitate disassembly, maintenance, cleaning, or washing of the wearable clothing equipment; The first sub-adhesive can be connected to the first master adhesive, and the notch design facilitates ventilation and air exchange through the filter screen. Simultaneously, contact electrodes ensure circuit continuity.

[0008] Preferably, the contact electrode is made of silver fiber material.

[0009] Furthermore, electrical connection can be achieved through contact electrodes, allowing the wearable device to be washed directly after the corresponding parts are removed; the connection between the controller and the wearable device is also achieved through contact electrodes, with a common adhesive strip between the controller and the wearable device for a full connection, and contact electrodes are placed on opposite sides of the controller and the wearable device for electrical connection.

[0010] Preferably, the mounting plate is fixed with positioning plates at the four corners of its upper end, and the positioning plates have limit holes. The upper end of the mounting plate abuts against the housing assembly. Two connecting brackets are fixed inside the housing assembly. A plug-in mechanism is installed inside the connecting brackets. Two crossbars are provided on the plug-in mechanism. Abutting rollers are installed on the crossbars. Two crossbars located within the same connecting frame extend to both sides of the connecting frame. Positioning plates on the same side form a group. The two connecting frames are respectively positioned between the two groups of positioning plates. The lower end of the housing assembly has two insertion holes on both sides. The four insertion holes correspond to the four limiting holes. The abutment rollers can abut against the positioning plates and penetrate the limiting holes and the corresponding insertion holes.

[0011] Furthermore, when the housing assembly moves toward the mounting plate, the contact roller can contact the positioning plate and then separate from the insertion hole. The tension spring and the return spring allow the crossbar to move away from the inner wall of the housing assembly under the action of the contact roller, while also having a return force, which facilitates quick insertion into the limiting hole and the insertion hole. During disassembly, the crossbar can be moved out of the limiting hole by inserting the rod into the insertion hole, which facilitates disassembly.

[0012] Preferably, the insertion mechanism includes a slide rail fixed inside the connecting frame, a reset mechanism on the slide rail, a movable frame on the reset mechanism, and a horizontal shaft through which the lower ends of the two movable frames pass. The horizontal shaft and the connecting frame are fixedly connected. Sliding members are slidably installed at both ends of the horizontal shaft. Horizontal and vertical members are fixed on the sliding members. The two horizontal members are respectively fixed on the two horizontal and vertical members. A reset spring is fixed between the sliding members and the movable frames.

[0013] Furthermore, when the housing assembly is pressed down, the contact roller and the positioning plate come into contact, and the contact roller contacts the side wall of the positioning plate and corresponds to the limiting hole. Through the action of the tension spring and the return spring, the contact roller can quickly pass through the limiting hole and the insertion hole, and it is easy for the contact roller to move out of the limiting hole and the insertion hole.

[0014] Preferably, the reset mechanism includes a tension spring fixed on the inner opposite sidewall of the slide rail, and the tension spring and the movable frame are fixedly connected.

[0015] Furthermore, the tension spring helps to quickly reset the movable frame by pushing the sliding member back to its original position via the reset spring, so that after the contact roller contacts the positioning plate and aligns with the limiting hole, it can be quickly inserted into the insertion hole on the housing assembly.

[0016] Preferably, the slide rail has a U-shaped structure, and both ends of the slide rail are fixed inside the connecting frame.

[0017] Furthermore, the U-shaped design facilitates the installation and fixation of the slide rail components, and enables the movable frame to move stably along the slide rail components.

[0018] Preferably, the positioning plate and the inner wall of the housing assembly abut each other.

[0019] Furthermore, the four positioning plates can respectively abut against the four corners inside the housing assembly to fully realize the connection and fixation between the housing assembly and the mounting plate.

[0020] Preferably, the mobile terminal and the controller establish a wireless communication connection via Bluetooth, and the mobile terminal has an APP system installed. The APP system includes a signal receiving module, a signal processing module, a data storage module, a display module, and an early warning module. The signal receiving module receives and initially filters the ECG signals transmitted by the controller. The signal processing module amplifies, filters, and extracts features from the ECG signals. The data storage module stores user information and ECG-related data. The display module displays ECG data and analysis results in chart form. The early warning module issues warning prompts when ECG parameters are abnormal.

[0021] Furthermore, the mobile app can receive, display, and control data within the controller; The signal receiving module is used to receive the ECG signal transmitted by the controller via Bluetooth and to perform preliminary filtering of the signal to remove interference noise during transmission. Signal processing module: Processes the received raw ECG signals, including signal amplification, filtering, feature extraction such as heart rate, QRS complex and other feature parameters, and generates standardized ECG data and analysis results; Data storage module: Used to store users' personal information, raw ECG data, and processed analysis results; supports querying and exporting historical data. Display module: Displays ECG data and analysis results intuitively in the form of charts such as ECG waveforms and heart rate trend graphs, making it convenient for users to view in real time; Early warning module: It presets the normal range threshold for ECG parameters. When the analysis results show that the ECG parameters exceed the threshold, it issues an early warning to the user through sound, pop-up window and other means, and supports one-click sharing with emergency contacts.

[0022] The present invention also proposes a method for fixing flexible circuits in smart wearable devices, comprising the following steps: S1: The mounting plate and the mounting base are fixedly connected by the first master glue and the first daughter glue, and the housing assembly and the mounting plate are detachably connected to facilitate connection with wearable clothing devices and to facilitate the maintenance of the components inside the housing assembly and the mounting plate. S2: Install the mobile terminal between the mounting plate and the housing assembly, so that the flexible circuit board is connected to the contact electrodes on the second sub-adhesive through the conductive cloth, so that the flexible circuit board can be electrically connected to the controller. S3: Attach conductive foam to the top and bottom ends of the flexible circuit board, with the two conductive foams at the top and bottom ends respectively contacting the top of the housing assembly and the top of the mounting plate. S4: Connect the housing assembly and mounting plate, which can be detachably connected via corresponding components for inspection and maintenance; S5: Wearable devices can detect the wearer's condition so that it can be displayed in a mobile app and controlled via the mobile app.

[0023] The beneficial effects of this invention are: 1. The flexible circuit board can be clamped by two conductive foams. The conductive foam is a flexible material to effectively protect the flexible circuit board and fully clamp the flexible circuit board to ensure its stability, so as to ensure the connection effect between the conductive cloth and the flexible circuit board. 2. The flexible circuit board on the conductive cloth and the second adhesive uses separate contact electrodes made of silver fiber material. It is detachably connected to the conductive cloth base by Velcro. Most of the materials of the wearable device and the conductive cloth fixing device are waterproof and washable. The contact electrodes can be removed in advance when washing, which solves the problem that existing ECG clothing is difficult to wash, ensures the hygiene and safety of the equipment, and extends the service life of the equipment. 3. The precise ECG signal receiving APP system and controller communicate wirelessly via Bluetooth to realize the real-time reception, processing, storage and display of ECG signals. It has feature extraction and early warning functions, which not only makes it convenient for users to keep track of their own ECG status in real time, but also provides timely warnings when abnormalities occur, thereby improving the user experience and the practicality of ECG monitoring.
