Description

Technical Field

[0001] The utility model relates to the technical field of intelligent steering wheel monitoring, and particularly relates to an electrocardiogram and blood oxygen detection device embedded in an automobile steering wheel. Background Art

[0002] With the development of the Chinese economy, people's living standards have been significantly improved, and private car travel has become the norm in Chinese residents' lives. While enjoying the convenience brought by private car travel, ensuring driving safety has become the primary issue. However, every year, due to the poor physical condition of drivers, such as physical discomfort, fatigue, myocardial infarction, arrhythmia, etc., or common cardiovascular health problems, it is very easy to cause traffic accidents. Therefore, to ensure driving safety, it is generally necessary to conduct self-detection and monitoring of the driver's body, especially the electrocardiogram and blood oxygen conditions, to ensure the driver's physical health during the driving process.

[0003] During the driving process of a vehicle, traditional electrocardiogram and blood oxygen detection devices cannot detect the driver's body in real time. Therefore, for example, in existing patents (a driver health detection steering wheel and an intelligent vehicle with the application number CN202221741873.4 and a steering wheel structure of an automobile for measuring human health indicators with the application number CN201920983446.9), the detection structure is often set on the steering wheel.

[0004] However, during the actual driving process of some drivers, due to non-standard driving, there is a state where the hand is separated from the steering wheel, resulting in the detection device on the steering wheel being unable to detect and monitor the driver's electrocardiogram and blood oxygen conditions in real time.

[0005] Therefore, in combination with the existing fingerprint unlocking technology and the existing steering wheel electronic lock technology, this application specifically proposes an electrocardiogram and blood oxygen detection device embedded in an automobile steering wheel to solve the above technical problems. Content of the Utility Model

[0006] The main purpose of the utility model is to provide an electrocardiogram and blood oxygen detection device embedded in an automobile steering wheel, which can not only greatly avoid the situation of the steering wheel being released during the driving state of the driver, but also detect the blood oxygen and electrocardiogram of the driver and display them in time, facilitating the driver to monitor his own physical condition in real time during the driving process, and at the same time, sending out an alarm in time when the driver's body appears abnormal or the emotion appears abnormally excited.

[0007] To solve the above technical problems, the utility model provides an electrocardiogram and blood oxygen detection device embedded in an automobile steering wheel, which is installed on the steering wheel main body and includes:

[0008] Two groups of identification and detection devices are provided on the steering wheel body for detecting the fingerprint data, electrocardiogram signal data, and blood oxygen content data of the driver;

[0009] A steering lock device is provided on the steering wheel body for limiting and locking the rotation direction of the steering wheel body, and is electrically connected to an alarm device to issue an alarm;

[0010] A display device is provided on the steering wheel body for obtaining, processing, and displaying the data information detected by the identification and detection device through a data processor;

[0011] When the identification and detection device identifies that the driver's fingerprint is in a normal state, the steering lock device does not operate, and the steering wheel body rotates normally.

[0012] Furthermore, the identification and detection device includes a mounting housing installed on the steering wheel body and having an open end for placing the driver's finger tip, a collection screen located inside the mounting housing for fitting the driver's finger fingerprint, a fingerprint recognition module provided on the mounting housing and connected to the collection screen for collecting and recognizing the fingerprint of the finger in contact with the collection screen, and at least two groups of electrocardiogram detection modules provided inside the mounting housing for detecting the electrocardiogram signal data of the driver. The fingerprint recognition module is connected to the steering lock device through a data transmission line for controlling the operation and driving of the steering lock device.

[0013] Furthermore, the identification and detection device further includes at least two groups of LED light-emitting modules located inside the mounting housing, and a blood oxygen detection module is provided inside the mounting housing for cooperating with the LED light-emitting modules to detect the blood oxygen concentration at the driver's finger tip.

[0014] Furthermore, the LED light-emitting module is set as an infrared LED light module of 880nm.

[0015] Furthermore, the identification and detection device further includes an induction module for inducing the driver's finger extending into the mounting housing and driving the operation of the fingerprint recognition module, electrocardiogram detection module, and blood oxygen detection module.

[0016] Furthermore, the electrocardiogram detection module includes a groove located inside the mounting housing, an electrocardiogram sensor located inside the groove for detecting the electrocardiogram signal data of the driver through the driver's finger tip, a spring cavity opened on the side wall of the groove, and a compression spring located inside the spring cavity for driving the electrocardiogram sensor to move outward from the groove.

[0017] Furthermore, the electrocardiogram detection module further includes a limiting structure provided on the mounting housing for limiting the linear movement of the electrocardiogram sensor inside the mounting housing.

[0018] Furthermore, the alarm device is installed on the steering wheel body for judging the data information detected by the identification and detection device through a data processor and issuing an alarm;

[0019] When the fingerprint recognition module fails to recognize the driver's fingerprint, the alarm device emits an alarm.

[0020] The beneficial effects of the present utility model are reflected in:

[0021] 1. By connecting the steering lock device with the recognition and detection device, the present utility model uses the fingerprint recognition module of the recognition and detection device to recognize the driver's fingerprint and control the driving steering wheel to unlock and rotate, without triggering an alarm. It can not only play the role of vehicle anti-theft during driving or avoid accidental operations such as external snatching of the steering wheel, but also avoid the situation where the driver's hands are off the steering wheel during driving, resulting in the inability to timely obtain the driver's electrocardiogram and blood oxygen condition information. It is convenient and practical, and can improve the safety of the driver when driving the vehicle.

[0022] 2. The present utility model detects the driver's fingerprint data, electrocardiogram signal data and blood oxygen content data through the recognition and detection device, and processes the detected data information through the data processor and displays it in a timely manner on the display device, which is convenient for the driver to monitor his own physical condition in real time during driving. At the same time, an alarm is issued in a timely manner when the driver's body appears abnormal or the mood appears abnormally excited. It can not only improve the safety of the driver when driving the vehicle, but also facilitate the driver to monitor his own physical condition in real time.

[0023] 3. By setting at least two groups of electrocardiogram detection modules and arranging electrocardiogram sensors in the grooves of the installation housing, and using the compression spring to drive the electrocardiogram sensors to move outward from the grooves, it can ensure continuous adhesion to the outer surface of the driver's finger. It can not only ensure that the electrocardiogram information data of the driver can be collected in a timely manner when the driver's finger is located inside the installation housing, but also ensure the accuracy of the detection of the driver's electrocardiogram signal data.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In the embodiment, refer in detail to Figures 1 to 4 .

[0033] As Figure 1 and Figure 4 shown, the present invention provides an electrocardiogram and blood oxygen detection device embedded in an automobile steering wheel, which is installed on the steering wheel main body 1 and includes:

[0034] Two groups of identification and detection devices 2, which are arranged on the steering wheel main body 1 for detecting fingerprint data, electrocardiogram signal data and blood oxygen content data of the driver;

[0035] A steering lock device 3, which is arranged on the steering wheel main body 1 for limiting and locking the rotation direction of the steering wheel main body 1, and is electrically connected to an alarm device 6 to issue an alarm;

[0036] A display device 5, which is arranged on the steering wheel main body 1 for obtaining, processing and displaying the data information detected by the identification and detection device 2 through a data processor 4;

[0037] When the identification and detection device 2 identifies that the driver's fingerprint is in a normal state, the steering lock device 3 and the alarm device 6 do not operate, and the steering wheel main body 1 rotates normally.

[0038] In specific implementation, the identification and detection device 2 is connected to the steering lock device 3. The identification and detection device 2 is used to identify the driver's fingerprint and control the driving of the steering wheel to unlock and rotate, without triggering an alarm. At this time, it can play a role in preventing theft during vehicle driving or avoid accidental operations such as external grabbing of the steering wheel. When the driver's hand leaves the steering wheel during the process of driving the vehicle (when the finger leaves the identification and detection device 2), a corresponding sound alarm will be triggered through the alarm device 6, prompting the driver's hand to always remain connected to the identification and detection device 2. This can not only ensure the safety of the driver when driving the vehicle, but also avoid the situation where the steering wheel is released from the driver's hand during the driving state, resulting in the inability to timely obtain the driver's electrocardiogram and blood oxygen status information, facilitating the convenient, efficient and practical acquisition of the driver's physical condition information.

[0039] It should be noted here that in the normal state: when the identification and detection device 2 misidentifies the driver's fingerprint, a sound alarm will be issued through the alarm device 6 and the corresponding fingerprint information will be displayed and stored through the display device 5, which is convenient for subsequent police investigation and handling.

[0040] It should be noted that the above-mentioned steering lock device 3 can directly refer to the ESCL steering wheel electronic lock structure in the prior art; the above-mentioned display device 5 can refer to the existing patent (a network data storage device with edge computing, application number CN202222747921.7), and its device internally has a data storage device and can perform edge computing processing according to the usage scenario and usage conditions; the above-mentioned alarm device 6 can directly adopt the buzzer in the prior art (or, for example, the existing public patent with application number CN201010215211.9: an electric vehicle alarm device), and different intelligent sound-emitting devices can also be used depending on the situation; the above-mentioned data processor 4 is composed of an amplifier, an analog-to-digital converter and a system computer. Among them, the data information detected by the identification and detection device 2 is sequentially converted into digital information through the amplifier and the analog-to-digital converter, and after data processing in the system computer, it is sent to the display device 5 for data display, or when the data processing exceeds the set threshold (thresholds are set for both electrocardiogram signals and blood oxygen data to prevent the driver from suffering from sudden cardiovascular diseases or heart diseases), an alarm is issued through the alarm device 6 to prompt the driver. Here, the system computer can adopt any data processing chip in the prior art.

[0041] Specifically, such as Figure 2 and Figure 4As shown in the figure, the identification and detection device 2 includes a mounting housing 21 installed on the steering wheel body 1 and having one end open for placing the driver's finger tip, a collection screen 22 located inside the mounting housing 21 for fitting the driver's finger fingerprint, a fingerprint recognition module 23 provided on the mounting housing 21 and connected to the collection screen 22 for collecting and recognizing the fingerprint of the finger fitting on the collection screen 22, and at least two groups of electrocardiogram detection modules 24 provided inside the mounting housing 21 for detecting the electrocardiogram signal data of the driver. The fingerprint recognition module 23 is connected to the steering lock device 3 through a data transmission line for controlling the operation and drive of the steering lock device 3.

[0042] At this time, the alarm device 6 is installed on the steering wheel body 1 for judging and issuing an alarm about the data information detected by the identification and detection device 2 through the data processor 4, that is, when the fingerprint recognition module 23 fails to recognize the driver's fingerprint state, the alarm device 6 issues an alarm.

[0043] Therefore, the fingerprint data, electrocardiogram signal data and blood oxygen content data of the driver are detected by the identification and detection device 2, and the detected data information is processed by the data processor 4 and displayed in a timely manner on the display device 5, which is convenient for the driver to monitor his own physical condition in real time during driving. At the same time, when the driver's body appears abnormal or the mood appears abnormally excited, an alarm is issued in a timely manner, which can not only improve the safety of the driver driving the vehicle, but also facilitate the driver to monitor his own physical condition in real time.

[0044] Specifically, when the driver's finger is inside the mounting housing 21, when the finger fingerprint is attached to the collection screen 22, the fingerprint recognition module 23 can recognize the driver's fingerprint information, and then determine the driver's identity information. The electrocardiogram detection modules 24 of the two groups of identification and detection devices 2 can detect the electrocardiogram information of the driver through the driver's finger.

[0045] It should be noted that both the collection screen 22 and the fingerprint recognition module 23 here are prior arts (reference can be made to the existing public patent: a wristband type electrocardiogram and blood oxygen meter with the application number CN201420323471.1).

[0046] At the same time, it can be further explained that two groups of identification and detection devices 2 are provided on the steering wheel body for the driver to use with both hands. To avoid the driver's hand fatigue, when the identification and detection device 2 stops driving and operating the steering lock device 3, the two identification and detection devices 2 can be arranged on the same series circuit, so that when the driver is driving the vehicle and changes hands to touch the other identification and detection device 2, the steering lock device 3 is still not triggered to operate, ensuring the normal driving of the vehicle.

[0047] In addition, the recognition and detection device 2 further includes at least two groups of LED light-emitting modules 27 located inside the installation housing 21. A blood oxygen detection module 25 is arranged inside the installation housing 21 to cooperate with the LED light-emitting module 27 to detect the blood oxygen concentration at the fingertip of the driver. The LED light-emitting module 27 is set as an infrared LED light module of 880 nm.

[0048] During the use of the recognition and detection device 2, the blood oxygen detection module 25 belongs to the prior art, and a detection device using the existing blood oxygen detection principle can be directly adopted (existing blood oxygen detection principle: emitting light, then receiving the optical signal, and calculating the blood oxygen value through the optical difference).

[0049] In addition, the recognition and detection device 2 further includes an induction module 26, which is used to sense the driver's finger extending into the installation housing 21 and drive the fingerprint recognition module 23, the electrocardiogram detection module 24, and the blood oxygen detection module 25 to operate.

[0050] The induction module 26 can sense whether the driver's finger extends into the installation housing 21. Since the driving operation of the fingerprint recognition module 23, the electrocardiogram detection module 24, and the blood oxygen detection module 25 is driven after being sensed by the induction module 26, the power supply loss during the actual use of the recognition and detection device 2 can be greatly saved.

[0051] The induction module 26 here can directly adopt an infrared induction device in the prior art.

[0052] In a specific embodiment, as Figure 3 shown, the electrocardiogram detection module 24 includes a groove 245 located inside the installation housing 21, an electrocardiogram sensor 244 located inside the groove 245 for detecting the electrocardiogram signal data of the driver through the fingertip of the driver, a spring cavity 241 opened on the side wall of the groove 245, and a compression spring 242 located inside the spring cavity 241 for driving the electrocardiogram sensor 244 to move outward from the groove 245.

[0053] Therefore, in the specific implementation, by setting at least two groups of electrocardiogram detection modules 24 and arranging the electrocardiogram sensor 244 inside the groove 245 of the installation housing 21 and using the compression spring 242 to drive the electrocardiogram sensor 244 to move outward from the groove 245, it can ensure continuous adhesion to the outer surface of the driver's finger, which can not only ensure timely collection of the driver's electrocardiogram information data when the driver's finger is located inside the installation housing 21, but also ensure the accuracy of the detection of the driver's electrocardiogram signal data.

[0054] At this time, it needs to be further explained that the electrocardiogram detection module 24 further includes a limiting structure 243 arranged on the installation housing 21 for limiting the linear movement of the electrocardiogram sensor 244 inside the installation housing 21.

[0055] The limiting structure 243 here can be, for example, Figure 3 a sliding rod and a chute-slider structure as shown to limit the sliding of the electrocardiogram sensor 244, or other publicly available limiting structures 243 can be used to limit the moving position of the electrocardiogram sensor 244.

[0056] The electrocardiogram sensor 244 here can directly adopt the electrocardiogram sensor in the prior art (reference can be made to the publicly available patent: a steering wheel with a safety prompt function, application number CN201420630932.X).

[0057] Finally, it should be noted that usually the identification and detection device 2 is powered and driven by the vehicle power supply. However, depending on the actual usage situation, a replaceable independent power supply can also be installed in the device for the overall power supply of the device.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0059] In addition, it should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0060] In addition, if there are descriptions such as "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" can explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or the solution where A and B are satisfied simultaneously. In addition, in the embodiments of the present invention, "a plurality" means two or more. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
