Detailed Implementation

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Please refer to Figures 1 to 5 As shown, this embodiment provides a smart handle for a fitness rowing machine, including a handle body 8 for controlling the fitness rowing machine and a monitoring module. The monitoring module is connected to the handle body 8. The monitoring module includes a Bluetooth SOC chip 1, an attitude sensor module 2, an optically distributed heart rate sensor 3, and a counting module 6. The attitude sensor module 2, the optically distributed heart rate sensor 3, and the counting module 6 are all electrically connected to the Bluetooth SOC chip 1. The Bluetooth SOC chip 1 is connected to an external terminal signal. An operation button 5 is installed on the handle body 8, and the operation button 5 is electrically connected to the Bluetooth SOC chip 1. In this embodiment, the attitude sensor module 2 is an accelerometer. In this embodiment, the external terminal includes, but is not limited to, a smartphone or a tablet computer.

[0031] This fitness rowing machine features a smart handle that integrates exercise data collection, heart rate monitoring, and VR interactive operation. It uses a counting module 6 combined with a posture sensor module 2 to acquire the user's real-time exercise status. A Bluetooth SOC chip 1 calculates the user's current posture and exercise data, which is then wirelessly transmitted to an external terminal. The transmitted data includes the current stroke frequency and stroke count of the handle body 8, the movement posture of the handle body 8, and the status of the operation buttons 5. The external terminal uses the received data for virtual reality operation, and combined with the operation buttons 5, it allows for a series of gameplay options, such as firing virtual bullets at the handle body 8 or throwing props. This achieves a seamless blend of entertainment and fitness, solving the problem of monotony associated with traditional rowing machines and providing users with a completely new fitness experience through the integration of advanced sensor technology and VR interactive operation.

[0032] In this embodiment, the counting module 6 includes an upper liner 601, a lower liner 603, a bolt 605, and a hinge seat 608. The upper liner 601 is fixed inside the handle body 8. The lower liner 603 is movably disposed below the upper liner 601. A magnet 602 is fixedly installed on the inner top of the upper liner 601. The hinge seat 608 is disposed above the upper liner 601. The lower end of the bolt 605 slides through the hinge seat 608, the upper liner 601, and the lower liner 603 in sequence and is threaded with a nut 606. A spring 607 is sleeved on the bolt 605. The top of the spring 607 abuts against the inner top of the upper liner 601, and the bottom of the spring 607 presses against the top of the lower liner 603. A reed switch 604 is fixedly installed on the lower liner 603. The signal output terminal of the reed switch 604 is electrically connected to the Bluetooth SOC chip 1.

[0033] In this embodiment, the hinge seat 608 is fixedly tied with a strap 609 by a pin. In order to facilitate the disassembly and assembly of the handle body 8 and the rowing machine, a connecting buckle 610 is fixedly sewn to the upper end of the strap 609.

[0034] By adopting the above technical solution, when the user pulls the handle body 8, the strap 609 is fixedly connected to the rowing machine through the connecting buckle 610, and the strap 609 is fixedly connected to the hinge seat 608 through the pin. This causes the hinge seat 608 to move the lower liner 603 towards the upper liner 601 through the bolt 605. At this time, the spring 607 is in a state of continuous compression. When the lower liner 603 moves the reed switch 604 towards the magnet 602 to the sensing distance range, the reed switch 604 is turned on and sends the sensing signal to the Bluetooth SOC chip 1. This is recorded as a valid motion count. That is to say, when the handle body 8 is pulled, the reed switch 604 moves towards the magnet 602 and is turned on. When the handle body 8 is released, the reed switch 604 moves away from the magnet 602 under the elastic force of the spring 607 and is turned off. With this setting, the motion count data of equipment such as rowing machines can be easily and accurately obtained. Among them, Bluetooth SOC chip 1 can be Nordic Semiconductor RF52832 Bluetooth SOC chip. This chip is a powerful low-power Bluetooth SoC that supports Bluetooth 5.0 and has a high-performance ARM Cortex-M4F processor, making it suitable for applications that require low power consumption and high-speed processing capabilities.

[0035] The attitude sensor module 2 can use the MPU6050 attitude sensor, which is a commonly used six-axis motion tracking device that integrates a three-axis gyroscope and a three-axis accelerometer. It can communicate with the main controller via I2C or SPI interface and is widely used in mobile phones, tablets, wearable devices, game controllers and other fields.

[0036] The photo-dissolved heart rate sensor 3 can be equipped with the Maxim Integrated MAX30102 photo-dissolved heart rate sensor. This sensor integrates the functions of a photoelectric pulse oximeter and a heart rate monitor. It detects heart rate and blood oxygen saturation by measuring changes in blood absorption of light. It is suitable for monitoring users' physiological indicators in fitness equipment and solves the problem of low accuracy of traditional handheld photoelectric heart rate sensors.

[0037] In this embodiment, an LED display screen 4 is installed on the handle body 8. The LED display screen 4 is electrically connected to the Bluetooth SOC chip 1. The LED display screen 4 allows users to directly view motion data on the handle body 8.

[0038] The Bluetooth SOC chip 1, posture sensor module 2, and counting module 6 are all located inside the handle body 8. The photo-particle heart rate sensor 3 is embedded in the LED display screen 4. The LED display screen 4 has a cutout for accommodating the photo-particle heart rate sensor 3. The photo-particle heart rate sensor 3 is used to monitor the user's heart rate changes in real time. When a finger is pressed on the photo-particle heart rate sensor 3, the photo-particle heart rate sensor 3 can measure the user's heart rate changes.

[0039] Specifically, the back of the handle bar at both ends of the handle body 8 is provided with a hand grip groove 801. With the hand grip groove 801, the user will have a better feel when holding the handle body 8.

[0040] Specifically, to make it more flexible and convenient for users to hold the handle body 8, a power module 7 for power supply is installed inside the handle body 8. In this embodiment, the power module 7 includes a rechargeable lithium battery.

[0041] Specifically, the handle body 8 has a charging port 9, and the power module 7 also includes a charging power management module. The rechargeable lithium battery is electrically connected to the charging power management module, and the charging interface of the charging power management module is plugged into the charging port 9. The charging power management module ensures that the battery is charged safely and efficiently.

[0042] As can be seen from the above, the smart handle of the rowing machine in this embodiment integrates multiple sensors and modules to achieve functions such as exercise data collection, heart rate monitoring, and VR interactive operation, providing users with a brand-new fitness experience. Its working principle is summarized as follows:

[0043] Data collection and monitoring:

[0044] Attitude sensor module (such as MPU6050): Real-time acquisition of user motion attitude data, including acceleration and rotation rate, and communication with Bluetooth SOC chip (such as Nordic Semiconductor nRF52832) via I2C or SPI interface.

[0045] Photodissolved heart rate sensor (such as Maxim Integrated MAX30102): Embedded in a cutout in an LED display, the user presses their finger on the sensor, and the heart rate is monitored in real time by measuring changes in the blood's absorption of light, and the data is sent to the Bluetooth SOC chip.

[0046] Motion counting:

[0047] The counting module consists of an upper liner, a lower liner, bolts, springs, and a reed switch. When the handle is pulled, the lower liner moves via the strap and hinge. When the reed switch approaches the magnet at a certain distance, it conducts, sending a signal to the Bluetooth SOC chip, which records one valid movement count. When the handle is released, the spring returns the lower liner to its original position, and the reed switch disengages.

[0048] Data transmission and processing:

[0049] Bluetooth SOC chip: Receives data from the attitude sensor module, photodissolved heart rate sensor, and counting module, performs preliminary processing, and wirelessly transmits motion status (such as stroke rate, stroke count, and attitude), heart rate data, and operation button status to external terminals (such as smartphones and tablets) via Bluetooth.

[0050] VR interactive operation:

[0051] After receiving data from the Bluetooth SOC chip, the external terminal performs virtual reality operations. Combined with operation buttons, it enables interactive game functions such as firing virtual bullets and throwing props, increasing the fun and challenge of fitness.

[0052] Display and power supply:

[0053] LED display screen: Displays motion data, allowing users to view it directly on the controller.

[0054] Power module: Includes a rechargeable lithium battery and a charging power management module, which supplies power to the system through the charging port to ensure long-term use.

[0055] User experience optimization:

[0056] The handle itself is designed with a hand grip groove to improve grip comfort.

[0057] The internally installed power module and charging port design ensure the device's portability and battery life.

[0058] In summary, the smart handle of the rowing machine in this embodiment, through advanced sensor technology and VR interactive operation, not only solves the problem of the monotony and boredom of traditional rowing machines, but also brings users a brand-new fitness experience, making the fitness process more interesting and efficient.
