Description

Technical Field

[0001] The present invention relates to a head cover for a car, in particular to a head cover for electrical stimulation used for assisting in detecting driver fatigue or mental state. Background Art

[0002] It's easy to get tired while driving, especially when driving alone without others to remind you or keep you alert. Drivers can experience fatigue symptoms such as sluggishness, slow reactions, and a lack of concentration. This can lead to decreased ability to handle unexpected traffic situations, which can cause accidents. For example, a Chinese utility model patent, "An Anti-Fatigue Driving System for Automobiles," with patent number ZL201220275221.6 (authorization publication number CN202686330U), discloses a system comprising a camera mounted below the rearview mirror, a processor with state recognition, a body control module, and an in-car audio system. The camera is connected to the processor, which in turn is connected to the body control module, which in turn is connected to the in-car audio system. This system uses the camera to detect the driver's pupil vibration frequency, effectively determining whether the driver is driving fatigued. If so, an alarm alerts the driver. If the system determines the driver is driving recklessly, it reduces the vehicle's speed, ensuring driving safety. In addition to fatigue driving, road rage and other factors, the main causes of traffic accidents, the driver's mental state also directly affects the driving safety of the vehicle. However, with the progress of society and the accelerated pace of life, we have to speed up the pace to keep up with the development of society, which brings about increased pressure in life. According to statistics from the China Sleep Research Society, the incidence of insomnia in Chinese adults is as high as 38.2%, and the number of people with sleep disorders has reached 300 million, and is increasing year by year.

[0003] At present, in response to the above problems, the applicant has independently developed a structure such as the Chinese utility model patent with patent number ZL202022221155.1 (authorization publication number CN212756790U) "A vehicle-mounted emotional therapy device", which discloses the use of a helmet installed in front of the original headrest of the car seat, and an electrode part that can cover the temporal lobe area of ​​the passenger's head. A helmet with an electrode part is set in the original headrest of the car, thereby assisting in treating passenger anxiety. The helmet is connected to the seat through a storage box and a driving mechanism and a swing mechanism, so that the helmet can change the relative position of the helmet in real time, so that the passenger's head and body remain relatively stable, thereby improving the passenger's car experience. It has good application prospects. Among them, the electrode part covering the temporal lobe area of ​​the passenger's head is used to assist in treating the passenger's anxiety, but the helmet cannot adapt well to the size of the driver's head. In order to better identify the passenger's anxiety, the vehicle-mounted emotional therapy device can be improved in another way. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide another head cover for electrical stimulation suitable for use in automobiles in response to the above-mentioned existing technical status.

[0005] The second technical problem to be solved by the present invention is to provide a head cover for electrical stimulation that can better adapt to the size of the driver's head in response to the above-mentioned existing technical status.

[0006] The third technical problem to be solved by the present invention is to provide a head cover for electrical stimulation that can adapt to the subtle movements of the driver's head in response to the above-mentioned existing technical status.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: the head cover for electrical stimulation includes a head cover connected to the headrest of the car seat, characterized in that it also includes:

[0008] The electrode part can cover the temporal lobe area of ​​the driver's head;

[0009] an electrode fixing portion connected to the head cover and connected to the electrode portion to fix the electrode portion; and

[0010] A steering wheel having two flexible electrode pieces connected to the left and right ends of the steering wheel respectively and an embedded chip connected to the two flexible electrode pieces by wires. The embedded chip has an electrocardiogram detection module and a neural network module, which converts electrical signals collected by the flexible electrode pieces into electrocardiogram signals to obtain electrocardiogram data, and judges the driver's emotional state based on the electrocardiogram data; when it is judged that the driver's mental state is abnormal, the electrode part is driven to cover the temporal lobe area of ​​the driver's head, thereby changing the driver's mental state.

[0011] Furthermore, the ECG detection module is used to detect the driver's ECG data while driving, complete the collection and storage of the driver's ECG data, and transmit the ECG data to the neural network module. The neural network module uses a pre-trained neural network model and transmits the collected ECG data of the driver during driving as input to the neural network model to classify the driver's mental state and obtain the driver's mental state during driving, thereby completing the detection of the driver's mental state. Of course, in addition to using the steering wheel's embedded chip to obtain the driver's mental state during driving, the camera's image processing and pattern recognition technology can also be used. The system includes a face positioning module, an eye state determination module, a mouth state determination module, and a fatigue determination module. The face positioning module is connected and communicated with the eye state determination module and the mouth state determination module, and the determination results are transmitted to the mental state determination module.

[0012] To address the second technical problem, preferably, a connecting plate for connecting the electrode fixing portion is provided within the head cover. The electrode fixing portion includes a first electrode fixing seat and a second electrode fixing seat, respectively disposed at opposite ends of the connecting plate. The first electrode fixing seat and the second electrode fixing seat are respectively provided with a first motor to drive the electrode fixing portion and the electrode portion connected to the first and second electrode fixing seats to rotate together. By driving the electrode fixing portion and the electrode portion connected to the first and second electrode fixing seats to rotate together, the electrode fixing portion and the electrode portion can be adaptively adjusted according to the head position of different drivers.

[0013] Also, in order to achieve adaptive adjustment of the electrode fixing part and the electrode part according to the head position of different drivers, preferably, the first electrode fixing seat, the second electrode fixing seat and the electrode fixing part and the electrode part corresponding thereto are connected by a first connecting arm and a second connecting arm that are hinged to each other, the first end of the first connecting arm is connected to the electrode fixing part, the second end of the first connecting arm is connected to the third end of the second connecting arm, the fourth end of the second connecting arm is connected to the first electrode fixing seat or the second electrode fixing seat, and a second motor is provided at the connection between the second end of the first connecting arm and the third end of the second connecting arm, and the second motor drives the relative rotation angle of the first connecting arm and the second connecting arm, thereby adaptively adjusting the rotation angle of the correspondingly connected electrode fixing part and the electrode part relative to the driver.

[0014] To address the third technical problem, preferably, the center of the connecting plate is separated into a first connecting plate and a second connecting plate, the first connecting plate being connected to the first electrode holder, and the second connecting plate being connected to the second electrode holder. Adjustment mechanisms are provided in the centers of the first and second connecting plates to adjust the relative expansion and contraction between the first and second electrode holders, and the adjustment mechanisms are confined to an adjustment plate located below the connecting plate. By controlling the relative expansion and contraction between the first and second electrode holders through the adjustment mechanisms, the electrode holders and the electrode portions can adaptively follow the driver's head as it rotates.

[0015] In addition, in order to adapt to the forward or backward movement of the driver's head during driving or braking, preferably, a first connecting seat extending along the driver's driving direction is provided under the first connecting plate, and correspondingly, a second connecting seat also extending along the driver's driving direction is provided under the second connecting plate. The first connecting seat and the second connecting seat are open ends facing the first connecting plate and the second connecting plate, and the two ends of the adjustment plate are respectively inserted into the open ends of the first connecting seat and the second connecting seat, so that the adjustment plate and the adjustment mechanism arranged thereon can move back and forth along the driver's driving direction.

[0016] The structural design of the adjustment mechanism is preferably such that the adjustment mechanism includes a first driven gear meshing with the end of the first connecting plate and a second driven gear meshing with the end of the second connecting plate, the first driven gear and the second driven gear being meshed with each other, and the adjustment plate is further provided with a driving wheel meshing with the first driven gear, the driving wheel being provided with a third motor for driving rotation below the adjustment plate. The rotation of the third motor drives the driving wheel to rotate forward or reverse, thereby driving the electrode fixing portion and the electrode portion corresponding to the first driven gear and the second driven gear to rotate toward a relative expansion or contraction angle.

[0017] Furthermore, a vertical plate extends downwardly from the adjustment plate and is perpendicular thereto. A fourth motor is connected to the vertical plate to drive the adjustment plate to reciprocate along the open ends of the first and second connecting seats and in the driver's driving direction. The power output of the fourth motor is connected to the vertical plate. Because the vertical plate and the adjustment plate are integrally connected, the fourth motor's power output is connected to the vertical plate, allowing the adjustment plate to adjust its position relative to the first and second connecting seats, thereby adaptively following the driver's head movements during driving.

[0018] In order to stimulate the vagus nerve of the driver's ear, preferably, the head cover is further connected to earmuffs that can communicate with the embedded chip, and the earmuffs are provided with clips that can be clamped on the driver's ears.

[0019] To enable the electrode portion to rotate around the driver's temporal lobe, the electrode fixing portion is preferably bowl-shaped, with the electrode portion positioned in the center and rotatable circumferentially. The electrode fixing portion is secured to the driver's temporal lobe, while the rotating electrode portion rotates around the driver's temporal lobe, thereby enabling the driver to change their mental state while driving.

[0020] Compared with the existing technology, the advantage of the present invention is that when the driver holds both sides of the steering wheel body, both palms need to contact the flexible electrodes on both sides at the same time for a certain period of time or more. The duration needs to be set manually, and the electrocardiogram detection module inside the embedded chip converts the electrical signal transmitted from the flexible electrode into the required electrocardiogram signal. The electrocardiogram signal is input into the neural network module to judge the mental state, such as anxiety or non-anxiety, and then outputs a 40Hz alternating current signal to the electrode part to relieve the driver's emotions. It has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 6The figure shows the best embodiment of the present invention. In this embodiment, the head cover 2 for electrical stimulation includes a head cover 2 connected to the headrest of the car seat 1, an electrode portion 3 that can cover the temporal lobe area of ​​the driver's head, an electrode fixing portion 4 connected to the head cover 2 and connected to the electrode portion 3 to fix the electrode portion 3, and a steering wheel 5. The steering wheel 5 has two flexible electrodes connected to the left and right ends of the steering wheel 5 respectively, and an embedded chip connected to the two flexible electrodes by wires. The embedded chip has an electrocardiogram detection module and a neural network module, which converts the electrical signals collected by the flexible electrodes into electrocardiogram signals to obtain electrocardiogram data, and judges the driver's emotional state based on the electrocardiogram data. When the driver's mental state is determined to be abnormal, the electrode portion 3 is driven to cover the driver's temporal lobe area, thereby changing the driver's mental state. When the driver grips both sides of the steering wheel 5, both palms must simultaneously contact the flexible electrodes on both sides for a predetermined period of time. The duration is manually set. The ECG detection module within the embedded chip converts the electrical signals transmitted by the flexible electrodes into the required ECG signals. This ECG signal is input into the neural network module to determine the driver's mental state, such as anxiety or non-anxiety. A 40Hz AC signal is then output to the electrode portion 3 to alleviate the driver's mood. To enable the electrode portion 3 to rotate around the driver's temporal lobe area, the electrode fixing portion 4 is bowl-shaped. The electrode portion 3 is located in the center of the electrode fixing portion 4 and can rotate circumferentially. The fixing portion of the electrode portion 3 is fixed to the driver's temporal lobe area, while the rotating electrode portion 3 can rotate around the driver's temporal lobe area, thereby enabling the driver to change his or her mental state while driving.

[0029] Specifically, the ECG detection module is used to detect the ECG data of the driver during driving, complete the collection and storage of the driver's ECG data, and send the ECG data to the neural network module; the neural network module uses a pre-trained neural network model, and transmits the collected ECG data of the driver during driving as input to the neural network model to classify the driver's mental state, and obtain the driver's mental state during driving, thereby completing the detection of the driver's mental state. Of course, in addition to using the embedded chip of the steering wheel 5 to obtain the driver's mental state during driving, the image processing and pattern recognition technology of the camera can also be used. The system includes a face positioning module, a human eye state judgment module, a mouth state judgment module and a fatigue judgment module. The face positioning module is connected to and communicates with the human eye state judgment module and the mouth state judgment module, and the judgment result is transmitted to the mental state judgment module. The two together make a judgment on the driver's mental state. The specific flexible electrode, embedded chip, ECG detection module and neural network module are all existing technologies, not shown in the figure, and will not be repeated here.

[0030] In order to better adapt to the size of the driver's head, a connecting plate 6 for connecting the electrode fixing part 4 is provided in the head cover 2 of this embodiment. The electrode fixing part 4 includes a first electrode fixing seat 41 and a second electrode fixing seat 42 respectively arranged at both ends of the connecting plate 6 and opposite to each other. The first electrode fixing seat 41 and the second electrode fixing seat 42 are respectively provided with a first motor 420 to drive the electrode fixing part 4 and the electrode part 3 correspondingly connected to the first electrode fixing seat 41 and the second electrode fixing seat 42 to rotate together. By driving the electrode fixing part 4 and the electrode part 3 correspondingly connected to the first electrode fixing seat 41 and the second electrode fixing seat 42 to rotate together, the electrode fixing part 4 and the electrode part 3 can be adaptively adjusted according to the head position of different drivers. Similarly, in order to achieve adaptive adjustment of the electrode fixing part 4 and the electrode part 3 according to the head position of different drivers, the first electrode fixing seat 41, the second electrode fixing seat 42 and the electrode fixing part 4 and the electrode part 3 corresponding thereto in this embodiment are connected by a first connecting arm 7 and a second connecting arm 8 that are hinged to each other. The first end 71 of the first connecting arm 7 is connected to the electrode fixing part 4, the second end 72 of the first connecting arm 7 is connected to the third end 81 of the second connecting arm 8, and the fourth end 82 of the second connecting arm 8 is connected to the first electrode fixing seat 41 or the second electrode fixing seat 42. A second motor 73 is provided at the connection between the second end 72 of the first connecting arm 7 and the third end 81 of the second connecting arm 8. The second motor 73 drives the relative rotation angle of the first connecting arm 7 and the second connecting arm 8, thereby adaptively adjusting the rotation angle of the correspondingly connected electrode fixing part 4 and the electrode part 3 relative to the driver.

[0031] In order to adapt to the changes in the driver's head, the center of the connecting plate 6 of this embodiment is separated into a first connecting plate 61 and a second connecting plate 62. The first connecting plate 61 is connected to the first electrode fixing seat 41, and the second connecting plate 62 is connected to the second electrode fixing seat 42. An adjusting mechanism 9 that can adjust the relative expansion and contraction between the first electrode fixing seat 41 and the second electrode fixing seat 42 is provided in the center of the first connecting plate 61 and the second connecting plate 62. The adjusting mechanism 9 is restricted on the adjusting plate 10 located under the connecting plate 6. The relative expansion and contraction between the first electrode fixing seat 41 and the second electrode fixing seat 42 is controlled by the adjusting mechanism 9, so that when the driver's head rotates, the electrode fixing part 4 and the electrode part 3 can adaptively follow the expansion and contraction of the driver's head. In addition, in order to adapt to the forward or backward movement of the driver's head during driving or braking, a first connecting seat 610 extending along the driver's driving direction is provided under the first connecting plate 61. Correspondingly, a second connecting seat 620 also extending along the driver's driving direction is provided under the second connecting plate 62. The first connecting seat 610 and the second connecting seat 620 are open ends facing the first connecting plate 61 and the second connecting plate 62. The two ends of the adjustment plate 10 are respectively inserted into the open ends of the first connecting seat 610 and the second connecting seat 620, so that the adjustment plate 10 and the adjustment mechanism 9 arranged thereon can move back and forth along the driver's driving direction. The structural design of the adjustment mechanism 9 is preferably such that the adjustment mechanism 9 includes a first driven gear 91 meshing with the end of the first connecting plate 61 and a second driven gear 92 meshing with the end of the second connecting plate 62. The first driven gear 91 and the second driven gear 92 are meshed with each other, and the adjustment plate 10 is further provided with a driving wheel 93 meshing with the first driven gear 91. The driving wheel 93 is provided with a third motor 94 under the adjustment plate 10 to drive its rotation. The rotation of the third motor 94 drives the driving wheel 93 to rotate forward or reverse, thereby driving the electrode fixing portion 4 and the electrode portion 3 corresponding to the first driven gear 91 and the second driven gear 92 to rotate toward a relative expansion or contraction angle. The adjustment plate 10 also extends downwardly from a vertical plate 20 perpendicular thereto. A fourth motor 30 is connected to the vertical plate 20, driving the adjustment plate 10 to reciprocate along the open ends of the first and second connecting seats 610, 620, and in the driver's driving direction. The power output of the fourth motor 30 is connected to the vertical plate 20. Since the vertical plate 20 and the adjustment plate 10 are integrally connected, the power output of the fourth motor 30 is connected to the vertical plate 20, thereby enabling the adjustment plate 10 to adjust its position relative to the first and second connecting seats 610, 620, thereby adaptively following the driver's head movements while driving. Finally, to stimulate the driver's vagus nerves, the hood 2 is also connected to earmuffs 40 that can communicate with the embedded chip. The earmuffs 40 are provided with clips 50 that can be clamped to the driver's ears.

[0032] The method of using the head cover 2 for electrical stimulation is as follows: when the driver is driving a car, he needs to touch the flexible electrodes on both sides with both palms at the same time for a certain period of time or more, and the duration needs to be set manually. The ECG detection module inside the embedded chip converts the electrical signal transmitted by the flexible electrodes into the required ECG signal, which is input into the neural network module to judge the mental state, such as anxiety or non-anxiety, and then outputs a 40Hz AC signal to the electrode part 3 to relieve the driver's mood. In order to fix the electrode fixing part 4 and the electrode part 3 on the driver's temporal lobe area, the electrode fixing part 4 and the electrode part 3 are fixed by the fixed electrode. The positioning device collects the position change data of the driver relative to the electrode fixing part 4 and the electrode part 3, and processes the data to obtain the change data to control the rotation of the first motor 420, the second motor 73, the third motor 94 and the fourth motor 30, so that the electrode fixing part 4 and the electrode part 3 can move forward or backward, expand or contract, rotate or non-rotate relative to the driver's temporal lobe area to adapt to the subtle movements of the driver's head, meet the needs of relieving the mental state while improving comfort. The mental state of this embodiment mainly refers to anxiety, of course, it can also be adjusted to be irritable, angry, drowsy, etc.

[0033] In addition, in addition to utilizing the electrical signal conversion method of the flexible electrode on the steering wheel, the camera 80 set on the vehicle frame can also be combined with the recording method. The number of cameras 80 can be selected as needed to better judge the driver's mental state.
