Description

Technical Field

[0001] This application relates to the field of automotive driving structures, and more particularly to a vehicle seat for monitoring driver vital signs. Background Technology

[0002] With the rapid development of the automotive industry and the continuous increase in car ownership, people are increasingly concerned about vehicle safety while enjoying the convenience it brings. Traditional automotive safety technologies mainly focus on collision safety protection, such as airbags, seat belts, and reinforced vehicle body structures. These technologies can provide effective protection for occupants in the event of a collision, significantly reducing the risk of injury or death. However, in addition to external factors such as vehicle collisions, the driver's own physical condition is also an important factor that cannot be ignored in the causes of traffic accidents.

[0003] In recent years, traffic accidents caused by drivers losing control of their vehicles due to sudden illnesses (such as heart disease, epilepsy, hypoglycemia, etc.) have become increasingly common. These accidents are often sudden, with drivers potentially losing control of the vehicle at the moment of onset, posing significant safety hazards to themselves, passengers, and other road users. Therefore, how to monitor drivers' vital signs in real time and accurately during driving, promptly identify potential health risks, and take corresponding measures to prevent accidents has become a crucial issue that urgently needs to be addressed in the field of automotive safety.

[0004] To meet the demand for driver vital sign monitoring, the automotive industry and related research institutions have begun to actively explore the possibility of applying vital sign monitoring technology to car seats. Currently, some car seat products with preliminary vital sign monitoring functions have appeared on the market. These products mainly collect some vital sign parameters of the driver by integrating different types of sensors into the seat.

[0005] For example, some seats use built-in pressure sensors to monitor the driver's posture and weight distribution, indirectly inferring the driver's physical condition. When the driver exhibits abnormal posture or changes in weight distribution due to discomfort, the sensors can capture these signals and issue an alert through the vehicle's system. Other seats employ photoelectric sensors, utilizing photoplethysmography (PPG) to measure physiological indicators such as the driver's heart rate and blood oxygen saturation. These technologies provide solutions for monitoring driver vital signs to some extent, but they also have some significant limitations.

[0006] Some vehicle seat sensor layouts lack scientific basis, failing to effectively cover key areas where the driver's body contacts the seat, resulting in incomplete monitoring data. Furthermore, some sensors have fixed installation methods, unable to be flexibly adjusted according to the driver's body shape and posture, which also affects monitoring accuracy and comfort. For example, if the sensor position does not make good contact with the driver's body, it may lead to inaccurate signal acquisition, or even a failure to acquire a valid signal.

[0007] Most existing vehicle seat vital signs monitoring systems operate independently of other vehicle control systems. The monitoring results are only used to issue simple alerts and cannot be effectively integrated with the vehicle's active safety systems (such as autonomous driving assistance systems and emergency braking systems). When a driver's health problem is detected, the vehicle cannot take timely measures to prevent an accident, thus reducing the practical value of vital signs monitoring technology.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0037] Specifically, such as Figures 1-5As shown in the embodiment of this application, a vehicle seat 100 for monitoring the vital signs of a driver is provided. The main body of the seat 100 is provided with a seat cushion 110 and a backrest 120. The overall structure of the seat 100 is the same as that of a traditional seat 100. A support component 300 and a sensing component 200 are provided on the seat 100. The support component 300 supports the sensing component 200, so that the sensing component 200 is located inside the seat 100, which facilitates the sensing component 200 to detect the vital signs of the person on the seat 100.

[0038] Specifically:

[0039] The support assembly 300 is provided with a first support member 310 and a second support member 320. The first support member 310 is disposed in the backrest 120 and supports the sensing component 200 in the backrest 120. The second support member 320 is disposed in the seat cushion 110 and supports the sensing component 200 in the seat cushion 110. The first support member 310 includes a main support rod 311 and a secondary support rod 312. The main support rod 311 is vertically installed along the backrest 120 and is connected to the conventional structural support of the backrest 120 to enhance the installation strength of the main support rod 311. A sensing component 200 is disposed at the top of the main support rod 311 near the headrest of the seat 100. The sensing component 200 detects the physiological characteristics of the driver's neck.

[0040] A secondary support rod 312 is provided on both sides of the main support rod 311. Multiple secondary support rods 312 are provided and connected to the main support rod 311. A sensing component 200 is provided at the end of the secondary support rod 312 away from the main support rod 311. Each secondary support rod 312 is equipped with a corresponding sensing component 200. The sensing components 200 are evenly installed inside the backrest 120 through the secondary support rods 312, so that when the driver sits on the seat 100, the sensing components 200 can detect the position of the human back. Through the setting of the secondary support rods 312, multiple sensor components can evenly and comprehensively detect the human back.

[0041] In this embodiment, the secondary support rods 312 are evenly distributed on the main support rods 311, and a slide rail 313 is provided on the secondary support rods 312 at a position away from the main support rods 311. The slide rail 313 connects to the end of the adjacent secondary support rods 312 away from the main support rods 311. A sensing component 200 is provided on the slide rail 313, and the sensing component 200 slides on the slide rail 313.

[0042] In this embodiment, the sensing component 200 mainly includes a support base 210 and a buffer 220. The support base 210 is mounted on a slide rail 313 and can be configured as a driving component that moves on the slide rail 313. The buffer 220 mounted on the support base 210 can buffer the sensor to a certain extent. The sensor is mounted on the buffer 220 at one end away from the support base 210 and is positioned close to the backrest 120, so that the sensor can directly detect the driver's physiological data.

[0043] The sensors used in this application are of various types. Preferably, the types of sensors used in this application can be pressure sensors, such as a flexible fabric pressure sensor implanted on the surface of the seat 100, which detects chest cavity deformation caused by breathing through pressure distribution and extracts respiratory frequency signals; at the same time, it judges the degree of fatigue based on the frequency of posture changes; a non-contact piezoelectric sensor can detect heart rate and breathing patterns, and calculate physiological parameters through chest cavity vibration signals without direct contact with the skin; a capacitive electrocardiogram (cECG) sensor is integrated on the surface of the seat 100, which detects electrocardiogram signals non-contactly through the principle of capacitive coupling, and can penetrate clothing to obtain heart rate data.

[0044] As described above, the buffer component 220 mainly includes a buffer spring, which connects the support base 210 and the sensor.

[0045] To better detect the physiological data of drivers and personnel, pressure plates 230 are installed at the output ends of some sensors. The installation of pressure plates 230 can better detect personnel.

[0046] Specifically, the second support member 320 includes a support frame 321, which is rectangular and horizontally positioned within the seat cushion 110. Multiple sensing components 200 are evenly distributed at the top of the support frame 321. These sensing components 200 comprehensively cover the pressure distribution over the driver's buttocks and thighs, enabling the sensors to more accurately monitor the driver's posture and weight distribution, providing crucial data for assessing the driver's physical condition.

[0047] Furthermore, pressure measuring plates 322 are also installed at the top of the support frame 321. Multiple pressure measuring plates 322 are installed, all horizontally. Multiple pressure measuring plates 322 and multiple sensing components 200 are sequentially mounted on the support frame 321, forming a dense monitoring network. This arrangement not only improves the accuracy of monitoring but also enables the system to more sensitively detect subtle changes in the driver's posture and weight distribution, providing the possibility for timely detection of potential health risks.

[0048] Furthermore, the pressure measuring board 322 is electrically connected to the control terminal 400, and the pressure data collected by the pressure measuring board 322 can be transmitted to the control terminal 400 in real time for analysis and processing. Based on this data, the control terminal 400 can further infer the driver's physical condition, such as whether there are potential risks such as fatigue driving or physical discomfort, and take corresponding measures to remind the driver or activate the vehicle's safety system.

[0049] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
