DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 , a wearable health monitoring PCBA, comprising a circuit board 1, to which a gyroscope sensor assembly 2 is connected;

[0027] The gyro sensor assembly 2 includes a mounting plate 201, to which a gyro sensor 202 is fixedly connected, and a shielding cover 203 is provided on the gyro sensor 202; the shielding cover 203 can effectively isolate the electromagnetic interference generated by the outside world and electronic components, reduce their influence on the gyro sensor 202, thereby improving the measurement accuracy and stability of the gyro sensor 202, which is particularly important for wearable health monitoring devices, because accurate data is the basis for evaluating the health status of users.

[0028] The bottom of the shielding cover 203 is fixedly connected with an inserting strip 204, and the top of the mounting plate 201 is provided with a slot 205, and the inserting strip 204 is movably inserted into the inside of the slot 205. By inserting the inserting strip 204 into the slot 205, the shielding cover 203 and the mounting plate 201 can be firmly connected. When the shielding cover 203 is damaged or needs to be replaced, it can be easily removed and a new shielding cover 203 can be installed, which greatly simplifies the repair and replacement process.

[0029] A fixing strip 206 is fixedly connected to the bottom of one side of the insert strip 204, a fixing groove 207 is provided at the bottom of the mounting plate 201, the fixing groove 207 is communicated with the slot 205, and the fixing strip 206 is movably inserted in the fixing groove 207. The cooperation between the fixing strip 206 and the fixing groove 207 provides an additional fixing point for the shielding cover 203, which increases the overall stability of the gyro sensor assembly 2 and reduces the possibility of loosening or displacement due to movement or external impact.

[0030] The sum of the lengths of the inserting strip 204 and the fixing strip 206 is equal to the length of the slot 205. The inserting strip 204 and the fixing strip 206 can be inserted into the slot 205, and the shielding cover 203 can be rotated to insert the fixing strip 206 into the fixing groove 207, which can effectively prevent the shielding cover 203 from loosening during use.

[0031] A receiving groove 208 is provided on the side of the inserting strip 204 away from the fixing strip 206, and a thrust spring 209 is fixedly connected inside the receiving groove 208, and one end of the thrust spring 209 abuts against the inner wall of the slot 205. When the inserting strip 204 is inserted into the slot 205, the thrust spring 209 is compressed, and the shielding cover 203 is rotated to insert the fixing strip 206 into the fixing groove 207, and the thrust spring 209 will try to restore to its original length, thereby providing an outward thrust, so that the fixing strip 206 is more tightly inserted into the fixing groove 207.

[0032] The top of the circuit board 1 is coated with a waterproof coating 3 , which can effectively prevent moisture from penetrating into the surface and interior of the circuit board 1 .

[0033] The top of the waterproof coating 3 is coated with an antistatic coating 4. The waterproof coating 3 ensures that the circuit board 1 can work normally in a humid environment and prevents moisture penetration from causing circuit failure, while the antistatic coating 4 provides protection against static electricity and prevents electrostatic discharge from damaging sensitive electronic components on the circuit board 1. This double protection significantly improves the reliability and durability of the circuit board 1.

[0034] A first foam adhesive 5 is bonded to one side of the top of the circuit board 1, and a second foam adhesive 6 is bonded to the other side of the top of the circuit board 1. The first foam adhesive 5 and the second foam adhesive 6 have compression deformation resistance and elastic durability, providing long-term shockproof protection for the circuit board 1. This shockproof performance can effectively absorb and reduce the impact of external shock or vibration on the circuit board 1, reducing the risk of component damage caused by vibration.

[0035] A health monitoring component is fixedly connected to the top of the circuit board 1. The health monitoring component includes a body temperature sensor, a heart rate sensor, a blood oxygen sensor and a blood pressure sensor.

[0036] The body temperature sensor is used to detect the body temperature information of the wearer. Specifically, the body temperature sensor is a thermistor or an integrated temperature sensor chip. In some embodiments, at least one body temperature sensor can be in contact with the user, and the detected temperature information is the user's body temperature information. Here, multiple body temperature sensors can be used to detect the same or close positions. For example, when detecting the user's body temperature, the skin near the same position can be detected to obtain multiple detection data. The circuit board 1 can optimize and analyze the multiple detection data, and obtain the optimized temperature value by taking the average value, etc., to improve the accuracy of the detection.

[0037] The heart rate sensor is used to detect the heart rate information of the wearer. In this embodiment, the heart rate sensor is arranged on the back of the circuit board 1 and is electrically connected to the circuit board 1. The back of the heart rate sensor is exposed to be able to contact the user. When the user wears it, the heart rate sensor contacts the human body, thereby detecting the heart rate information and transmitting it to the circuit board 1.

[0038] The blood oxygen sensor is arranged on the circuit board 1 and is used to detect the wearer's blood oxygen saturation. Blood oxygen saturation (SpO2) is the percentage of the capacity of oxygenated hemoglobin (HbO2) bound by oxygen in the blood to the capacity of all hemoglobin (Hb, hemoglobin) that can be bound, that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of respiratory circulation. Currently, photoelectric blood oxygen sensors can be reflective and transmissive. Reflective blood oxygen sensors such as Silicon Labs' (also known as "Core Technology") Si1171 biometric optical sensor. Transmissive blood oxygen sensors can use Silicon Labs' Si1181 biometric optical sensor (with PD+AFE integrated inside).

[0039] The blood pressure sensor is arranged on the circuit board 1 and is used to detect the wearer's blood pressure information. The blood pressure sensor is a high-accuracy, high-stability force-sensitive chip, such as an optical tool for measuring blood flow changes using photoplethysmography (PPG) and a thin-film force sensor for measuring pressure disclosed in a paper in the journal Science Translational Medicine. The skin touches the sensor, and the matching algorithm calculates the user's blood pressure information.

[0040] Working principle: When in use, the inserting strip 204 is inserted into the slot 205, the thrust spring 209 is compressed, and the shielding cover 203 is rotated to insert the fixing strip 206 into the fixing slot 207. The thrust spring 209 provides an outward thrust to make the fixing strip 206 more tightly inserted into the fixing slot 207, which can effectively prevent the shielding cover 203 from loosening during use;

[0041] The shielding cover 203 may be wrapped around the outside of the gyro sensor 202 , and the shielding cover 203 may effectively isolate electromagnetic interference generated by the outside world and electronic components, reduce their influence on the gyro sensor 202 , and thus improve the measurement accuracy and stability of the gyro sensor 202 .

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
