Description

Technical Field

[0001] The invention relates to the technical field of steering wheels, and in particular to a steering wheel with a heart rate monitoring structure. Background Art

[0002] The steering wheel in the prior art does not have the function of heart rate monitoring. Heart rate is one of the important indicators reflecting the physiological state of the human body. During driving, the driver's heart rate may change due to tension, fatigue, physical discomfort or sudden illness. If the steering wheel does not have the heart rate monitoring function, the driver cannot detect abnormal changes in his heart rate in time, and thus cannot take corresponding measures in time, such as resting, adjusting driving status or seeking medical help, which increases the risk of traffic accidents.

[0003] Therefore, it is necessary to design a steering wheel with a heart rate monitoring structure to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a steering wheel with a heart rate monitoring structure.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A steering wheel with a heart rate monitoring structure, comprising: Steering wheel body; The heart rate sensing module is located on the inner edge of the steering wheel body, close to the lower or side of the driver's hand holding area. This position is convenient for sensing the heart rate signal of the driver's wrist or finger without affecting normal driving operations. It is responsible for collecting the driver's heart rate data and uses a non-contact heart rate sensor to measure the heart rate by monitoring the changes in blood flow at the fingertips or wrists. The data processing module is built into the housing in the center area of ​​the steering wheel body and is integrated with the steering wheel electronic control system. It receives the data transmitted by the heart rate sensing module, performs signal amplification, filtering, analog-to-digital conversion, and compares and analyzes the data with the preset normal heart rate range to determine whether the driver's heart rate is within a safe range. The display and communication module is built into the housing in the center area of ​​the steering wheel body and is integrated into the smart cockpit system through software; The emergency notification module is built into the housing in the center area of ​​the steering wheel body, integrated at the software level of the data processing module, and physically connected to the on-board communication module to ensure the smooth delivery of the emergency notification. These communication modules are located in the communication control unit in the vehicle's central control area or trunk.

[0006] As a preferred technical solution of the present invention, in the heart rate sensing module, the non-contact heart rate sensor built into the heart rate sensing module adopts infrared photoelectric sensor technology. This sensor works by emitting infrared light of a specific wavelength and receiving its reflected light. When the infrared light is irradiated to the driver's fingertips or wrists, the hemoglobin in the blood will absorb part of the light, and the flowing blood will cause periodic changes in the intensity of the reflected light. This change is closely related to the heart's beating cycle. The sensor can calculate the driver's real-time heart rate by capturing and analyzing the changes in these light signals. The heart rate sensing module is not only responsible for collecting heart rate data, but also has preliminary data processing capabilities. The original light signal collected by the sensor will be amplified, filtered and analog-to-digital converted by the internal circuit to extract effective information related to the heart rate. The processed heart rate data will be transmitted to the vehicle's data processing center via a data cable or wirelessly for further analysis, display and storage.

[0007] As a preferred technical solution of the present invention, in the data processing module, the original heart rate signals sent by the heart rate sensing module are received through the data transmission interface. These signals are analog signals, containing heart rate information as well as noise and interference. The data processing module will first preprocess these signals, including signal amplification, filtering and analog-to-digital conversion. The preprocessed heart rate data will be sent to the core processing unit of the data processing module for further analysis. The module will compare and analyze according to the preset normal range of heart rate to determine whether the driver's heart rate is within a safe range. If the heart rate is within the normal range, the system will not take any action immediately, but will continue to monitor and update the heart rate data. If the heart rate exceeds the normal range, the system will issue a warning to the driver through sound, light signals or display screens, reminding him to pay attention to his physical condition and recommending rest or other safety measures. In extreme cases, such as severe abnormalities in the heart rate and continued unabated, the system will automatically trigger the emergency rescue process, contact the emergency center or send an alarm to the emergency contact.

[0008] As a preferred technical solution of the present invention, the display and communication module includes one or more small display screens for directly displaying vehicle information, navigation instructions, telephone communication status, and driving assistance information on the steering wheel, so that the driver can quickly obtain the required information while keeping his eyes on the road ahead. The module integrates Bluetooth and Wi-Fi wireless communication technologies, allowing the driver to quickly connect to mobile phones, smart watches and smart devices to realize phone making / answering, music playing, and voice assistant control functions. The display and communication module communicates and interacts with other parts of the smart cockpit system through software interfaces. These interfaces are based on standard communication protocols or dedicated communication protocols. The driver can access and control the various functions of the display and communication module through the user interface of the smart cockpit system. The display screen supports touch operation, allowing the driver to execute specific commands or adjust settings by tapping or sliding the screen.

[0009] As a preferred technical solution of the present invention, in the emergency notification module, the emergency notification module relies on the heart rate data provided by the data processing module. When an abnormal heart rate or other emergency health condition of the driver is detected, the module will immediately trigger the emergency response process. Once it is confirmed that an emergency notification needs to be sent, the emergency notification module will independently decide whether to send the emergency notification according to preset rules and conditions, and determine the content and priority of the notification. The emergency notification module is connected to the on-board communication module through a dedicated data line or bus interface. When the emergency notification module decides to send an emergency notification, it will send the notification content to the designated recipient through the on-board communication module, including an emergency center, an emergency contact or a remote service center of the vehicle manufacturer. The on-board communication module is located in a communication control unit in the central control area or the trunk of the vehicle. The control unit integrates multiple communication technologies to ensure that the vehicle can maintain communication with the outside world in various environments. The emergency notification module interacts with these control units through the on-board communication module.

[0010] The present invention has the following beneficial effects: 1. Improve driving safety: The heart rate sensing module can monitor the driver's heart rate changes in real time and promptly detect abnormal heart rate caused by fatigue, tension or physical discomfort, thereby preventing traffic accidents caused by poor driver condition. When the emergency notification module detects serious abnormal heart rate or other emergency situations, it can quickly send an emergency notification through the vehicle communication module to buy precious rescue time for the driver and reduce the risk of accidents; 2. Enhanced health monitoring capabilities: The non-contact heart rate sensor provides drivers with a convenient means of health monitoring. It can continuously monitor heart rate while driving without the need for additional equipment, helping drivers to understand their health status in a timely manner. The data processing module compares and analyzes the heart rate data with the preset range, providing drivers with instant feedback on whether their heart rate is within a safe range, encouraging drivers to pay attention to and manage their own health; 3. Improve driving experience: The display and communication module is integrated into the smart cockpit system through software, allowing the driver to easily view heart rate data, receive health tips or emergency notifications and other information, enhancing the information interactivity and convenience during driving. The integrated design on the steering wheel body reduces the need for the driver to distract attention to view or operate other devices, helping the driver to stay focused and improve the driving experience.
