[0049] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0050] In view of this, the applicant has conducted in-depth research and improvement exploration on the steering wheel and the health monitoring steering wheel, and found that the health monitoring steering wheel is used to monitor the driver's heart rate, electrocardiogram, blood oxygen content, respiratory rate, fatigue level, blood alcohol concentration and other vital signs in real time when the driver is driving the vehicle, and display them in real time. ECG (Electrocardiograph) ECG monitoring principle: a weak current is generated during the heartbeat, and the current is transmitted to various parts through human tissues. Different potential changes are shown in various parts of the human body surface. These potential changes are recorded to form a dynamic curve, which is the electrocardiogram.

[0051] Heart rate (HR) is the frequency of heart beats, and the average person's heart rate is between 60 and 90 beats per minute. Heart rate calculation: Heart rate is the number of heart beats per minute, which can be obtained by analyzing the changes in the ECG waveform:

[0052] Heart rate (beats / min) = 60 ÷ (RR cycle) = 60 ÷ (PP cycle)

[0053] Among them, the RR cycle reflects the ventricular rhythm, which refers to the time limit between two R waves; the PP cycle reflects the atrial rate, which refers to the time limit between two P waves.

[0054] The respiratory rate (RR) of a normal adult is 12 to 20 times per minute. Respiratory rate calculation: The breathing process modulates both the amplitude and period of the ECG waveform. By extracting the changes in the amplitude and period of the ECG waveform and filtering out interference, the changes in respiratory intensity can be calculated. The respiratory frequency can be calculated based on the period of intensity changes. A normal adult breathes 16 to 20 times per minute. More than 24 times / minute is considered fast breathing, and less than 12 times / minute is considered slow breathing.

[0055] At present, the car health monitoring steering wheels on the market mainly connect the electroplated parts with the ECU's wiring harness through screw connections to transmit the collected signals to the ECU, thereby monitoring the driver's heart rate, electrocardiogram, blood oxygen value and other vital signs and providing early warning, medical solutions and other related functions. However, under the requirement of being able to transmit the vital sign parameters collected by the electroplated parts to the steering wheel ECU in real time and display them, connecting the electroplated parts with the ECU's wiring harness through screw connections is slow. In addition, conductive leather has appeared on the market as a carrier for health monitoring steering wheels, but the conductive leather and the ECU's wiring harness are generally riveted, which is not only slow, but also not conducive to fixation.

There are two conductive components 2, which serve as electrodes and are respectively located at 3H / 9H of the steering wheel body, and are symmetrically arranged on the steering wheel body. 3H / 9H indicates that the hour hand of the clock indicates the 3 o'clock and 9 o'clock positions.

The first fixed body 5 is electrically connected to the controller 7 through the wiring harness 6, thereby realizing the electrical connection between the conductive member 2 and the controller 7.

The pin portion 16 is hollow, which facilitates the pin portion 16 to deform, and then facilitates the circumferential rib 11 to be inserted into the die-casting groove 18. By embedding the circumferential rib 11 in the side wall of the die-casting groove 18, the fixation of the plastic-coated part 502 in the frame 8 can be strengthened.

The end of the pin portion 16 is close to the bottom position of the die-casting groove 18.

The circumferential spring sheet 503 presses the frame 8 downward, and the circumferential ribs 11 press the frame 8 upward by using the upward elastic restoring force of the circumferential spring sheet 503 to form a locking structure. The circumferential spring sheet 503 is, for example, a plastic spring sheet, and the frame 8 is pressed downward by the circumferential spring sheet 503. The top of the circumferential rib 11 is horizontal, and the top of the circumferential rib 11 is pressed upward by using the upward elastic restoring force of the circumferential spring sheet 503 to press the part of the side wall of the die-casting groove 18 in the frame 8. The circumferential ribs 11 and the circumferential spring sheet 503 are mutually locked, which improves the stability of the plastic-coated part 502 in the frame 8.

[0065] In one embodiment, if Figure 1 , Fig. 9 and Fig.10 As shown, an insulating buckle 13 is provided on the conductive component 2, and the insulating buckle 13 is clamped with the steering wheel body to fix the conductive component 2 and the steering wheel body. The insulating buckle 13 is, for example, a plastic buckle. The insulating buckle 13 is clamped with the foam body 4 of the steering wheel body.
