[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] The purpose of this invention is to provide a wearable device for sports physiological detection to solve the problems existing in the prior art. It integrates electromyography (EMG) sensors and photoelectric sensors on the device body, so that it can be worn while acquiring relevant data of athletes in real time for timely feedback.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Please refer to the following: Figure 1 , Figure 2As shown, a wearable device for sports physiological monitoring is provided, including a watch body with a built-in motherboard, an electromyography (EMG) sensor for detecting muscle fatigue, and an optical sensor 8 for detecting heart rate and blood oxygen levels. Both the EMG sensor and the optical sensor 8 are electrically connected to the motherboard. The probes of the EMG sensor and the optical sensor 8 are positioned on the side of the watch body closest to the skin. The watch body includes a main body and a strap. Lugs 4 are located on both sides of the main body, and the strap is connected to the lugs 4. The main body houses the motherboard, the EMG sensor, and the photoelectric sensor. Through the strap, the watch body is worn on the forearm, upper arm, wrist, ankle, calf, and thigh. The EMG sensor detects muscle fatigue intensity at the wearing location, and the optical sensor 8 detects heart rate and blood oxygen levels. This allows for wearable sensor monitoring while acquiring muscle fatigue intensity, heart rate, and blood oxygen data related to exercise status, providing timely feedback on the exerciser's condition. The probes of both the EMG sensor and the optical sensor 8 protrude from the end face of the watch body, allowing for better contact with the skin and improving data detection accuracy.
[0029] In this embodiment, the optical sensor 8 is a PPG sensor.
[0030] In this embodiment, the probe of the electromyography (EMG) sensor includes an EMG positive electrode 12, an EMG negative electrode 10, and an EMG GND electrode 11 arranged in sequence. The EMG GND electrode 11 is located between the EMG positive electrode 12 and the EMG negative electrode 10 and is grounded. During device operation, the EMG positive electrode 12, the EMG negative electrode 10, and the EMG GND electrode 11 will collect the signals from the three EMG electrodes in real time. The EMG GND electrode 11 is grounded. The EMG positive electrode 12 and the EMG negative electrode 10 amplify the differential EMG signals through a differential amplifier while suppressing common-mode signal interference. Based on the changes in muscle signal amplitude and the amplitude level over a period of time, the duration and intensity of muscle exertion are graded to determine the degree of muscle fatigue.
[0031] Because athletes cannot constantly focus on observing their own physical condition during high-intensity sports activities and fire rescue operations, they need to be monitored by coaches or off-site commanders. Therefore, wearable sports physiological monitoring devices also include a remote information transmission module for transmitting monitoring information to a remote terminal, which can be a mobile device such as a mobile phone, tablet, or computer. The inclusion of the remote information transmission module expands the applicability of the device.
[0032] In this embodiment, a Bluetooth module is integrated on the motherboard. The Bluetooth module is electrically connected to a separately installed remote information transmission module. The separately installed remote information transmission module can be installed on a mobile phone or on a portable embedded system, such as a device integrated with a Raspberry Pi and 5G or LoRa communication modules. The Bluetooth module transmits data information to the remote information transmission module, which then transmits the data information to a remote terminal. The independent setting of the remote information transmission module helps to reduce the size of the watch body and improve its wearing comfort. The independently set remote information transmission module can be installed in a suitable position on the athlete's body. In another embodiment, the remote information transmission module is integrated on the motherboard.
[0033] To alert monitoring personnel that there is a risk in the current exercise status of the participants, an alarm device is installed on the remote terminal. The alarm device can be an alarm light or an alarm horn.
[0034] Based on the remote information transmission module, and when applied to situations where others need to monitor the athlete's movement status, the end of the watch body away from the human body can be sealed off, eliminating the display screen, saving energy, and increasing the device's usage time.
[0035] The meter has a built-in power supply to provide power to each module, and a charging terminal is provided on the meter for charging the power supply.
[0036] The motherboard also has a power monitoring module to transmit power data to a remote terminal, and an alarm device will sound when the power is low.
[0037] A gyroscope and an accelerometer can also be installed in the watch body to measure whether the athlete is moving. If the athlete is detected to be inactive for a long time, the remote terminal can issue an alarm.
[0038] An additional calculation module can be set up. The calculation module continuously acquires data measured by the optical sensor 8 multiple times, calculates the average value of the data and then outputs it to eliminate the interference caused by instantaneous motion on the data.
[0039] This embodiment also includes a charging base for use with the watch body. The charging end includes a contact positive electrode 6 and a contact negative electrode 7. The charging base is provided with a charging contact electrode negative electrode 21 and a charging contact electrode positive electrode 22. The contact positive electrode 6 and the charging contact electrode positive electrode 22 are arranged opposite to each other, and the contact negative electrode 7 and the charging contact electrode negative electrode 21 are arranged opposite to each other. Specifically, the contact positive electrode 6 and the contact negative electrode 7 are arranged on the end face of the watch body where the sensor probe is located, realizing convenient connection between the contact electrode and the charging contact electrode. The charging base is provided with a USB charging port 26. The charging base is provided with a receiving groove 24 for accommodating the probe of the electromyography sensor and the probe of the optical sensor 8. In actual use, the watch body can be directly placed on the charging base to achieve charging, improving charging convenience.
[0040] The charging base is equipped with buckles 23 around its perimeter, which are used to secure the meter body and improve the charging stability of the meter body.
[0041] The watch body is equipped with a power button 2 and an indicator light 1 for displaying the watch body's working status. The indicator light 1 can use multiple colors to represent its working status, such as blue for Bluetooth connection status, red for charging status, and green for charging completion status.
[0042] In this embodiment, the outer shell 3, the bottom shell 9, and the housing 25 of the charging base are all made of ABS plastic. The bottom shell 9 of the watch body is provided with screw fixing positions 5 for connecting to the outer shell 3 by screws.
[0043] An emergency alarm button can be installed on the meter body. By pressing the alarm button multiple times, the alarm device can automatically sound an alarm.
[0044] When using this equipment in a fire, it must be worn inside a fireproof suit.
[0045] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
