Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and particularly to an intelligent heart rate monitoring armband for running training. Background Art

[0002] With the wide application of heart rate monitoring technology in sports training and health management, wearable heart rate monitoring devices have become common auxiliary tools in high-intensity sports such as running. Traditional heart rate monitoring devices mostly adopt an armband structure, and the sensor is fixed to the arm through elastic webbing, Velcro or snap buttons, etc., and then the pulse wave signal on the skin surface is obtained for analysis.

[0003] However, in medium- and high-intensity running exercises, due to the violent swinging of the body, increased sweating, and loosening caused by long-term wearing, the armband often experiences displacement or detachment, resulting in unstable contact between the sensor and the skin, affecting the accuracy of heart rate signal acquisition and the stability of device use. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an intelligent heart rate monitoring armband for running training, which solves the problems of easy loosening of the armband, unstable fitting, and inaccurate heart rate signal acquisition in the prior art under the exercise state.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An intelligent heart rate monitoring armband for running training, including a waterproof block and a monitoring control system. A detection component is provided on the inner wall of the waterproof block, and a motor is fixedly connected to the inner wall of the waterproof block. The output end of the motor is fixedly connected to a transmission rod for driving an impeller to rotate inside the waterproof block. An airbag is installed at the bottom of the waterproof block, which is symmetrically arranged and communicated with the air outlet end of the impeller through an air pipe. Both ends of the two airbags are installed with communication pipes, and the communication pipes are used to communicate the airbags with the inside of the hollow plates on both sides of the inner wall of the waterproof block. A plurality of air outlet holes are provided at the bottom of the hollow plates, and the air outlet holes are communicated with a plurality of through grooves opened on both sides of the inner wall of the waterproof block for discharging the remaining air. A rhythm component is installed on the inner wall of the waterproof block.

[0006] Preferably, the rhythm component includes an elliptical block, the elliptical block is fixedly connected to the outer wall of the transmission rod, a contact plate is fixedly connected to the inner wall of the waterproof block, a rubber plate is provided at the bottom of the contact plate, a pressing block is slidably connected to the top of the rubber plate, and a spring is provided at the bottom of the pressing block.

[0007] Preferably, the detection component includes a detector, the detector is installed at the bottom of the waterproof block for detecting the heart rate, an arm ring is provided on the outer wall of the waterproof block, and a display screen is installed at the top of the waterproof block.

[0008] Preferably, a dust-proof net is installed on one side of the waterproof block to reduce the entry of external dust into the waterproof block and prevent the impeller from rotating.

[0009] Preferably, the elliptical block is slidably connected to the top of the extrusion block, and the spring is arranged on the top of the rubber plate.

[0010] Preferably, the extrusion block is slidably connected to the inner wall of the contact plate, and the contact plate is slidably connected to the inner wall of the rubber plate.

[0011] Preferably, the transmission rod is rotatably connected to one side of the outer wall of the dust-proof net and the inner wall of the waterproof block.

[0012] Preferably, the monitoring and control system includes:

[0013] A heart rate acquisition module for real-time acquisition of the wearer's heart rate data;

[0014] An MCU main control unit for processing heart rate data and controlling the coordinated operation of each module;

[0015] A motor drive control module for driving the impeller to rotate and adjusting the rhythm feedback frequency;

[0016] A rhythm control logic module for mapping heart rate data to a rhythm frequency and controlling rhythm feedback;

[0017] A display and human-computer interaction module for displaying heart rate data, setting and switching training modes, and providing a user interaction interface;

[0018] A power management module for providing stable power to each module.

[0019] Preferably, the MCU main control unit is electrically connected to the heart rate acquisition module, the motor drive control module, the rhythm control logic module, the display and human-computer interaction module, and the power management module respectively.

[0020] Preferably, the detector is electrically connected to the monitoring and control system, the motor is electrically connected to the monitoring and control system, and the display screen is electrically connected to the monitoring and control system.

[0021] Working principle: When the wearer uses this monitoring armband to monitor the heart rate during physical education teaching, first place the whole device on the upper arm through the arm ring, and then touch and control the monitoring and control system through the display screen to select the functions before use.

[0022] After the monitoring is turned on, the monitoring control system will first send an activation electrical signal to the motor, and then drive the impeller and the elliptical block connected by the transmission rod to rotate synchronously through the motor. After the impeller rotates, it will input wind power through the filtration of the dust-proof net and convey it to the airbag installed at the bottom of the waterproof block through the air pipe, so that it inflates and tightly adheres to the user's skin downward. By increasing the contact range to increase the friction force, the stability of the monitoring skin position between the waterproof block and the user is improved, avoiding the situation that the armband slides during physical education, such as long-distance running, which affects the accuracy of heart rate monitoring.

[0023] During the inflation process, the setting of multiple connecting pipes can prevent the airbag from over-inflating, and discharge the excess gas through the connection between the hollow plate and the through groove. Since multiple through grooves are arranged at one end between the two side airbags, the output air can increase the air flow speed near the user's skin, thereby promoting the drying of sweat stains, making the area around the skin detector worn dry in a ring shape, improving the wearing comfort, and reducing the adverse impact of sweat stains on heart rate monitoring.

[0024] During the application of the above functions, the monitoring control system will continuously cooperate with the detector to monitor the wearer's heart rate, and gradually adjust the motor output power in proportion as the heart rate rises to meet the armband monitoring status in different heart rate ranges.

[0025] In addition, when the elliptical block rotates following the transmission rod, it will periodically push the extrusion block to contact the rubber plate, so as to realize the deformation by squeezing the rubber plate through the extrusion block, so that the wearer can feel the periodic rhythm. And when the elliptical block does not contact the extrusion block, the spring will push the extrusion block to slide on the inner wall of the contact plate and return to the original position to wait for the next contact.

[0026] The present invention provides an intelligent heart rate monitoring armband for running training. It has the following beneficial effects:

[0027] 1. By setting a motor to drive the transmission rod to drive the impeller to rotate, and connecting the air outlet end of the impeller to the airbag through the air pipe, the present invention realizes the function of automatically driving the airbag to inflate during running, effectively improving the dynamic fitting function of the armband tightly adhering to the wearing part, avoiding the problem of the armband loosening, and being applicable to the heart rate monitoring effect under high-intensity exercise conditions.

[0028] 2. By setting an elliptical block on the transmission rod and constructing a structure in which the elliptical block drives the extrusion block to periodically contact the rubber plate, the present invention realizes the generation of rhythm feedback by using a mechanical structure without using an electric vibration device, obtaining the effect of conveying beat information to the user with low power consumption and high reliability, and effectively assisting in the control of the exercise rhythm.

[0029] 3. The present invention realizes the intelligent linkage of automatically adjusting the motor speed and the rhythm feedback frequency according to the real-time heart rate data by setting up a monitoring and control system composed of a heart rate acquisition module, an MCU main control unit, a motor drive control module, a rhythm control logic module, etc., achieving the effects of real-time synchronization of the training rhythm with the wearer's heart rate state and personalized rhythm guidance.

[0030] 4. The present invention realizes the automatic discharge of the remaining air generated after the airbag is inflated through structural guidance by setting up connecting pipes at both ends of the airbag and conducting the connecting pipes to the hollow plate and the air outlet structure, obtaining the effects of reducing the airbag pressure retention and improving the wearing comfort, and ensuring the stable operation of the armband air flow system during long-term training.

[0038] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment:

[0040] Please refer to the attached Figure 1 - attached Figure 6, an embodiment of the present invention provides an intelligent heart rate monitoring armband for running training, including a waterproof block 1 and a monitoring control system 4. The inner wall of the waterproof block 1 is fixedly connected with a motor 6, and the output end of the motor 6 is fixedly connected with a transmission rod 7 for driving an impeller 8 to rotate on the inner wall of the waterproof block 1. An airbag 11 is installed at the bottom of the waterproof block 1, which is symmetrically arranged and communicated with the air outlet end of the impeller 8 through an air pipe 10. Both ends of the two airbags 11 are installed with connecting pipes 12, and the connecting pipes 12 are used to communicate the airbags 11 with the inside of the hollow plates 13 installed on both sides of the inner wall of the waterproof block 1. The bottom of the hollow plate 13 is provided with a plurality of air outlets, and the air outlets are communicated with a plurality of through grooves 14 opened on both sides of the inner wall of the waterproof block 1 for discharging the remaining air. The transmission rod 7 is rotatably connected to one side of the outer wall of the dust-proof net 9, and the transmission rod 7 is rotatably connected to the inner wall of the waterproof block 1.

[0041] Specifically, it includes an integrally formed waterproof block 1. The inside of the waterproof block 1 is a cavity structure for accommodating a plurality of functional components. Its external contour is arc-shaped, fitting the user's upper arm, and the surface is treated with a sweat-proof and waterproof coating, suitable for outdoor sports scenarios.

[0042] The inner wall of the waterproof block 1 is fixedly connected with a motor 6. The motor 6 is a micro DC motor, which is small in size, light in weight, and has good moisture-proof performance in packaging. The output end of the motor 6 is coaxially connected with the transmission rod 7, and the connection method adopts an embedded fastening structure to avoid loosening or slipping during high-frequency operation. The transmission rod 7 is made of carbon fiber hollow rod material, which is impact-resistant and has good rigidity. One end passes through one side of the outer wall of the dust-proof net 9, and the other end is rotatably connected to the inner wall of the waterproof block 1 through a bushing, forming a stable and reliable rotation support mechanism.

[0043] On the transmission rod 7, a multi-wing impeller 8 is installed, and its rotation direction is consistent with the air flow direction. When the impeller 8 rotates, it can forcibly output air, and the air outlet is connected to the airbag 11 through an air pipe 10. The air pipe 10 is made of flexible silica gel, which is resistant to bending and tearing, and can ensure a stable ventilation connection in the wearing state.

[0044] The airbags 11 are symmetrically arranged on both sides of the bottom of the waterproof block 1, and their material is high-elastic silica gel, which has good repeatable inflation and deflation performance. When the impeller 8 works, air is continuously injected into the airbag 11 through the air pipe 10, causing the airbag 11 to automatically bulge, realizing the dynamic fitting of the armband. To avoid air pressure accumulation, both ends of the airbag 11 are connected with connecting pipes 12. The connecting pipes 12 penetrate through the inside of the waterproof block 1, and the ends extend to the inside of the hollow plates 13 installed on both sides of the inner wall of the waterproof block 1.

[0045] The hollow panels 13 are each provided with multiple air outlets at their base, connecting to slots 14 on either side of the inner wall of the waterproof block 1, forming a complete airflow channel. This structure allows excess air from the airbag 11 to be introduced into the hollow panels 13 via the connecting tubes 12 and then smoothly discharged through the air outlets and slots 14, preventing excessive inflation of the airbag 11 and ensuring both comfort and safety.

[0046] This structure uses a motor 6 to rotate a transmission rod 7, driving an impeller 8 to deliver air to an airbag 11, which inflates and fits the arm. The air is then discharged through a connecting tube 12 and a hollow plate 13, ultimately channeled out of the body through a slot 14, forming a closed-loop pneumatic circulation system. This structural design allows for dynamic adjustment of the armband's tightness, ensuring a snug fit and a comfortable feel even during high-intensity exercise like running.

[0047] The rhythm assembly includes an elliptical block 15, which is fixedly connected to the outer wall of the transmission rod 7. A contact plate 16 is fixedly connected to the inner wall of the waterproof block 1. A rubber plate 17 is provided at the bottom of the contact plate 16. An extrusion block 19 is slidably connected to the top of the rubber plate 17. A spring 18 is provided at the bottom of the extrusion block 19. The elliptical block 15 is slidably connected to the top of the extrusion block 19, and the spring 18 is provided at the top of the rubber plate 17. The extrusion block 19 is slidably connected to the inner wall of the contact plate 16, and the contact plate 16 is slidably connected to the inner wall of the rubber plate 17.

[0048] Specifically, the rhythm component is located inside the waterproof block 1. It has a compact structure and works in conjunction with the transmission structure to output rhythmic physical tactile signals to help the wearer control the running rhythm. The rhythm component mainly includes an elliptical block 15, a contact plate 16, a rubber plate 17, a spring 18, and a squeeze block 19.

[0049] Elliptical block 15 is a non-circular, eccentric component with an overall elliptical shape. Its central axial hole is located eccentrically, allowing it to be fixedly mounted on the outer wall of transmission rod 7. As transmission rod 7 rotates, elliptical block 15 rotates with it, causing its outer profile to periodically vary in height during each rotation, thereby providing intermittent lifting action on the substructure. Elliptical block 15 forms a sliding connection with extrusion block 19, ensuring a close fit during installation without locking it in place. This allows rotation of elliptical block 15 to push extrusion block 19 up and down.

[0050] The extrusion block 19 is located at the bottom of the elliptical block 15. Its main body is a vertically arranged rectangular three-dimensional structure made of a hard elastic material, which provides a certain degree of rigidity and resilience. A compression spring 18 is installed at its lower end. This spring 18 is vertically mounted between the rubber plate 17 and the extrusion block 19 and is normally in a compressed and preloaded state. The extrusion block 19 is lifted by the elliptical block 15 and then falls back under the restoring force of the spring 18, forming a regular up-and-down reciprocating motion, thus generating a contact and pressing effect.

[0051] Spring 18 is a medium-rigidity coil spring, its ends fixed to the top of rubber plate 17 and the bottom of extrusion block 19, respectively. Rubber plate 17 is a flat elastic cushioning layer installed at the bottom of contact plate 16, serving as a support surface for spring 18 and providing shock absorption. Made of a flexible material and of moderate thickness, rubber plate 17 can absorb a certain amount of mechanical impact, enhancing wearing comfort.

[0052] Contact plate 16 is a vertical guide-type structure, fixedly attached to the inner wall of waterproof block 1. It provides a position-limiting guide function. Its inner cavity is equipped with a vertical slot to constrain the movement of extrusion block 19. Extrusion block 19 slides within contact plate 16, preventing lateral displacement and allowing only vertical movement to ensure consistent rhythm feedback direction. Contact plate 16 is also connected to rubber plate 17 through a sliding connection, providing a flexible buffer space for the entire rhythm assembly when subjected to stress, preventing structural fatigue.

[0053] When the transmission rod 7 is driven by the motor 6, the elliptical block 15 begins to rotate as a follower. Its profile lifts and releases the extrusion block 19 once per rotation cycle. This process is counteracted by the spring 18, achieving a rhythmic physical push. The overall feedback frequency depends on the rotational speed of the transmission rod 7, which is in turn controlled by the output of the rhythm control logic module in the monitoring and control system 4.

[0054] The detection component includes a detector 5, which is installed at the bottom of the waterproof block 1 and is used to detect the heart rate. The outer wall of the waterproof block 1 is provided with an arm ring 3, and the top of the waterproof block 1 is installed with a display screen 2.

[0055] Specifically, the detection component is located at the bottom of the waterproof block 1 and is primarily used to monitor the wearer's heart rate in real time and feed the collected physiological data back to the monitoring and control system 4. This component includes a detector 5 mounted on the bottom surface of the waterproof block 1. Detector 5 is a skin-contact physiological signal acquisition device that uses photoplethysmography (PPG) technology. It incorporates a light-emitting diode (LED) and a photosensor. It acquires pulse waves by reflecting signals from changes in blood flow in the skin's microvessels, thereby accurately detecting heart rate.

[0056] To ensure detection accuracy, the bottom contour of the detector 5 slightly protrudes from the bottom surface of the waterproof block 1 to facilitate full contact with the skin.

[0057] Detector 5 and monitoring control system 4 are electrically connected to transmit signals. Heart rate data is processed in real time by the acquisition module in the control system and serves as the basis for rhythm feedback and rhythm frequency regulation. Data changes are synchronously updated on display screen 2, allowing the user to easily monitor their current physiological status.

[0058] The top of the waterproof block 1 is provided with a display screen 2. The display screen is a flexible micro OLED touch screen, which is compact in size but has sufficient brightness, and has the characteristics of high contrast and low power consumption. It can clearly display heart rate, rhythm level, training mode and device status information. Users can perform operations such as mode switching and rhythm feedback adjustment through simple swiping or touching, and cooperate with the human-computer interaction module to achieve intuitive control.

[0059] To ensure the stable wearing of the device during exercise, an armband 3 is provided on the outer wall of the waterproof block 1. The armband 3 adopts an elastic adjustable fixing structure, which can be quickly adjusted according to the thickness of the user's arm. The surface is made of anti-slip woven material, and the inner side is equipped with a soft cushion layer, which has good fit and breathability, and is not easy to slip or cause discomfort during long-term wearing. The armband 3 is connected to the waterproof block 1 through a buckle structure, and the installation and disassembly are convenient, which is convenient for the daily wearing and maintenance of the device.

[0060] A dust-proof net 9 is installed on one side of the waterproof block 1 to reduce the entry of external dust into the waterproof block 1 and prevent the impeller 8 from rotating.

[0061] Specifically, a dust-proof net 9 is provided on one side of the waterproof block 1. The dust-proof net 9 serves as the first protective structure on the air inlet path of the impeller 8, and is used to block external particulate matter from entering the waterproof block 1, effectively avoiding the interference of foreign objects such as dust, hair, and impurities on the rotation of the impeller 8 and the operation of the air flow channel.

[0062] The dust-proof net 9 is made of a microporous metal wire mesh or a medical-grade weather-resistant fiber material, and the pore diameter is between 0.2 and 0.5 mm. While ensuring good ventilation effect, it has a high filtration accuracy. Its structure is fixedly installed at the ventilation port opened on the side wall of the outer shell of the waterproof block 1 by a snap-on or screw connection method, and the installation is firm and not easy to loosen. There is an edge sealing rubber ring around the net frame, which fits tightly with the outer shell, enhances airtightness, and prevents fine dust from entering through the gap.

[0063] The inner side of the dust-proof net 9 is arranged adjacent to the outer side of the transmission rod 7. The transmission rod 7 forms a rotational connection support point with the outer wall of the dust-proof net 9 at this place, which not only plays a role in limiting and stabilizing the operation of the transmission shaft, but also further reduces the structural vibration and offset phenomenon, and improves the operation reliability of the whole machine.

[0064] Since the impeller 8 is a high-speed rotating component, its operating state is very sensitive to the intrusion of foreign objects. Once dust or fluff is inhaled, it may cause uneven air flow, a decrease in the output air volume, and even cause the bearing to jam. In this embodiment, the dust-proof net 9 is provided, which can significantly reduce such risks, and shows good protection effect in the actual long-term training application, and improves the durability and safety of the device.

[0065] The monitoring and control system 4 includes:

[0066] A heart rate acquisition module, which is used to acquire the heart rate data of the wearer in real time;

[0067] The MCU main control unit is used to process the heart rate data and control the coordinated operation of each module;

[0068] The motor drive control module is used to drive the impeller 8 to rotate and adjust the rhythm feedback frequency;

[0069] The rhythm control logic module is used to map the heart rate data into a rhythm frequency and control the rhythm feedback;

[0070] The display and human-computer interaction module is used to display the heart rate data, set and switch the training mode, and provide a user interaction interface;

[0071] The power management module is used to provide a stable power supply for each module.

[0072] The MCU main control unit is electrically connected to the heart rate acquisition module, the motor drive control module, the rhythm control logic module, the display and human-computer interaction module, and the power management module respectively. The detector 5 is electrically connected to the monitoring and control system 4, the motor 6 is electrically connected to the monitoring and control system 4, and the display screen 2 is electrically connected to the monitoring and control system 4.

[0073] Specifically, the system mainly includes: a heart rate acquisition module, an MCU main control unit, a motor drive control module, a rhythm control logic module, a display and human-computer interaction module, and a power management module.

[0074] Among them, the heart rate acquisition module is electrically connected to the detector 5 and is responsible for real-time acquisition of the wearer's heart rate information. The detector 5 is installed at the bottom of the waterproof block 1, fits the user's skin, obtains the pulse signal through PPG photoplethysmography technology, and transmits it to the MCU main control unit after preliminary amplification and filtering processing. The sampling frequency and sensitivity of the heart rate acquisition module are adjustable to adapt to the signal quality changes under different exercise intensities.

[0075] The MCU main control unit is the data processing and instruction distribution center of the entire system, and a multi-level judgment algorithm and training strategy model are running inside it. On the one hand, the main control unit receives the data from the heart rate acquisition module, performs dynamic filtering, smoothing processing and interval recognition on the data, and judges the current heart rate state; on the other hand, it issues control instructions to each functional module, including rhythm feedback adjustment, motor 6 operation state switching, display update, energy consumption scheduling and other operations.

[0076] The motor drive control module is electrically connected to the motor 6, adjusts the rotation speed of the motor 6 according to the control signal output by the MCU, and thus drives the change of the rotation frequency of the transmission rod 7 and the impeller 8. The rotation speed of the impeller 8 directly determines the inflation and deflation rhythm of the airbag 11, forming the basis of the beat feedback that the user can perceive. The drive module supports PWM speed regulation and soft start protection functions, and can achieve smooth transition during the rhythm change process to avoid discomfort caused by sudden changes.

[0077] The rhythm control logic module is a unique functional module of this system. Its function is to map and convert real-time heart rate data with a set rhythm model. According to the training mode setting, this module can correspond the target heart rate range to the rhythm frequency output. For example, the rhythm speeds up at high heart rates and slows down at low heart rates, realizing personalized feedback of "driving the exercise rhythm by the body state". The rhythm control logic supports multiple mapping functions, such as linear, piecewise, exponential, etc., which can be selected by the user or automatically adapted.

[0078] The display and human-machine interaction module is connected to the display screen 2 and is responsible for displaying information such as heart rate, rhythm level, and training mode in real time. The display screen 2 is set on the top of the waterproof block 1 and is a small OLED touch screen. Functions such as training mode switching, rhythm intensity adjustment, and system status viewing can be realized through gesture sliding or clicking. This module also includes expansion interfaces such as button input and vibration reminder to improve the convenience of user interaction.

[0079] The power management module provides stable power supply for each electronic component. This module is connected to the main battery pack and has overvoltage, overcurrent, and short-circuit protection functions, as well as low-power standby and intelligent wake-up strategies. When the system is running, the main control unit can adjust the power supply mode according to the task load to achieve optimal energy efficiency and extend the battery life of the device.

[0080] The MCU main control unit is electrically connected to each of the above modules respectively to form a complete control link. The detector 5, the motor 6, and the display screen 2 are all connected to the monitoring and control system 4 through signal lines to ensure fast system response, accurate data transmission, and timely feedback adjustment.

[0081] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
