[0023] Watch dial 1: A heart rate sensor 6 is installed on the back thereof for real-time monitoring of the user's heart rate. Armband connectors 2 for connecting to an armband 3 are provided on both sides of the watch dial 1.

[0024] Sealing ring 7: Installed on the back of the dial 1, surrounding the heart rate sensor 6. The sealing ring 7 is higher than the plane where the heart rate sensor 6 is located, which plays a role in preventing slipping and isolating the heart rate from inaccurate heart rate caused by water impact (when swimming).

[0025] Pressure detection unit 17: installed on the back of the dial 1 of the armband 3, the pressure detection unit 17 adopts a high-precision pressure sensor, such as a piezoresistive pressure sensor, which can accurately detect the pressure value between the armband 3 and the skin. Its measuring range is 0-1000 grams and the accuracy reaches ±5 grams to ensure sensitive capture of pressure changes.

[0026] Airbag module: installed in the strap of the armband 3, mainly includes an airbag body 11, an air pump 13 and a gas control valve 14. A mounting shell 8 is fixed in the middle position of the armband 3, and the air pump 13 is fixed in the mounting shell 8. Two airbag bodies 11 are provided, which are respectively located on both sides of the mounting shell 8. An air separator box 9 is also fixed in the mounting shell 8. The air pump 13 is connected to the air separator box 9 through a first pipe 12. Multiple hoses 10 at the ends of the airbag body 11 are respectively connected to the air separator box 9. The gas control valve 14 is installed on the first pipe 12. The airbag body 11 is made of soft and elastic rubber material, which does not affect the normal wearing comfort and fit of the armband 3 in the uninflated state; the air pump 13 is a miniature electric air pump, which can quickly respond to the instructions of the control unit 16 and provide sufficient inflation pressure; the gas control valve 14 is used to accurately control the inflation and deflation process of the airbag to ensure accurate control of the inflation volume and inflation speed.

[0027] Control unit 16: Connects pressure detection unit 17 and airbag module, and control unit 16 is fixed in mounting shell 8, and uses STM32 series single chip microcomputer as core processor. The control unit 16 is responsible for receiving pressure data transmitted by pressure detection unit 17, and making judgments and decisions based on preset algorithms and thresholds, so as to control the inflation operation of the airbag module. At the same time, control unit 16 also has the function of communicating with external devices such as smart phones, sports watches, etc., and can transmit data through wireless communication protocols such as Bluetooth, ANT+, such as the wearing status of armband 3, heart rate data if heart rate monitoring function is integrated, and receiving configuration instructions of external devices.

[0028] Power module 15: provides power for the pressure detection unit 17, the airbag module, and the control unit 16. It is located inside the mounting shell 8 and fixed on the top of the gas distribution box 9. It uses a rechargeable lithium battery with a capacity of 100-200 mAh and is equipped with a complete charging management circuit. It has overcharge protection, over-discharge protection, and short-circuit protection functions to ensure safe use of the battery and stable power supply.

[0029] Pressure change judgment formula Pressure change rate ,in It is the initial moment The pressure value detected, After a period of time The pressure value detected after that. Through a large amount of experimental data, it is determined that when the pressure is within 5 seconds (i.e. seconds) is continuously below 100g (the lower limit of normal wearing pressure set initially ), and the pressure drop rate Exceeding 10g / s (preset pressure drop rate threshold ), it is determined that the armband 3 may slip off. For example, if gram, gram, then g / s and , triggers the subsequent anti-falling action.

[0030] Calculation formula for the inflation amount of the airbag body 11 (approximate calculation) Assume that the inner circumference of armband 3 is (Unit: cm), the ideal thickness of the airbag body 11 after inflation is (Unit: cm), the width of the airbag body 11 is (Unit: cm), then the airbag body 11 is inflated After experimental optimization, for common armband 3 sizes, such as the inner circumference of the armband 3 cm, the ideal thickness of the airbag body 11 after inflation is designed cm, width cm, calculate the inflation volume ml, in actual application, it can be further fine-tuned according to the specifications of the armband 3 and the required holding force, for example, Milliliters are used as the standard inflation volume range to ensure that the airbag body 11 can provide sufficient clamping force after inflation to prevent the armband 3 from further slipping without causing excessive pressure on the wearer.

[0031] Inflation time calculation (based on inflation flow) The inflation flow rate of the known inflation pump 13 (Unit: ml / s), according to the required inflation volume Calculate inflation time For the selected inflator, the inflator flow rate ml / s, combined with the above selected inflation volume range ml, the inflation time In actual control, the inflation time can be set within 2-3 seconds to ensure that the slipping of the armband 3 is quickly and effectively prevented from worsening in the early stage of slipping, while avoiding the adverse effects of excessive inflation on the armband 3 and the wearer.

[0032] Working principle: When the pressure value detected by the pressure detection unit 17 reaches the preset slip threshold, a trigger signal is immediately sent to the control unit 16. After receiving the signal, the control unit 16 starts the inflation pump 13 and opens the gas control valve 14 at the same time, and controls the inflation of the airbag body 11 according to the preset inflation volume and inflation time. During the inflation process, the pressure detection unit 17 continuously monitors the pressure change. When the pressure rises back to the normal wearing range (such as 150-200 grams), the control unit 16 stops the inflation pump 13 and closes the gas control valve 14 to keep the air pressure in the airbag body 11 stable. If the pressure drops below the threshold again within a period of time after inflation (such as 10 seconds), the control unit 16 can start the inflation program again or send an alarm signal to remind the user to put on the armband 3 again.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
