[0007] In the above-mentioned intelligent reminder device for assisting vehicle driving, the driver takes out the driving assistance bracelet from the bracelet fixing slot and puts it on, and at the same time puts the electrode gloves on his fingers. If the piezoelectric sensor and the current sensor detect that the driver is anxious and tired while driving, the air pump is controlled to extract the gas in the air tank and blow air to the driver through the air outlet. At the same time, the solenoid valve is opened to control the gas in the air cavity to be filled into the soft cushion bin. The soft cushion bin expands and squeezes the wrist, and the buzzer sounds an alarm.

[0008] As a further improvement of the present application, a seat is installed in the cab, a safety belt opening is installed on the seat, a telescopic assembly is provided at the connection between the safety belt opening and the seat, the telescopic assembly includes a telescopic motor installed on the seat, a fixing plate installed at the output end of the telescopic motor, the fixing plate is fixed to the safety belt opening, and the control module is electrically connected to the telescopic motor.

[0015] To sum up, before driving the vehicle, the driver first takes out the driving assistance bracelet from the bracelet fixing slot and puts it on, and at the same time puts the electrode gloves on the fingers. The pressure button installed on the bracelet fixing slot detects that the driving assistance bracelet has been taken out before starting the car. After putting on the driving assistance bracelet, the tiny voltage applied by the voltage transmitter forms a closed circuit with the human body. The multiple piezoelectric sensors connected to the electrode gloves and the current sensor installed on the driving assistance bracelet monitor the human body current and voltage in real time and analyze and process them. If the driver's heart rate is detected to be too high after analysis, it is determined that the driver is anxious and fatigued when driving. The air pump installed in the steering wheel draws out the gas in the air tank and blows air to the driver through the air outlet, which has the effect of sobering up and reminding the driver at an angle that does not affect driving. At the same time, the solenoid valve opens to control the gas in the air cavity to fill the soft cushion chamber. The soft cushion chamber expands and squeezes the wrist, which reminds the driver again. The buzzer sounds an alarm to remind the driver of dangerous driving so that the driver can take mitigation measures. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-Figure 7An intelligent reminder device for assisting vehicle driving is shown, comprising a driving assistance wristband 1, a cab 2 and an intelligent controller 3. The driving assistance wristband 1 is installed in a wristband fixing groove 201 provided in the cab 2, and the driving assistance wristband 1 is fixed by the wristband fixing groove 201. A storage cover 101 is installed on the driving assistance wristband 1, and a storage bin is formed between the storage cover 101 and the driving assistance wristband 1 for storing an electrode glove 102. The electrode glove 102 is placed in the storage bin, and a plurality of piezoelectric sensors are connected to the electrode glove 102. The driver wears the electrode glove 102 and monitors the driver's body voltage in real time through the plurality of piezoelectric sensors connected thereto, and transmits the data to the detection module for collection and analysis. A padded bin 103 is provided on the driving assistance wristband 1, and an air cavity 104 is provided in the driving assistance wristband 1. The air cavity 104 The connection with the cushion chamber 103 is equipped with an electromagnetic valve and a micro air pump 105. When the detection module detects that the driver is driving dangerously, the control module controls the electromagnetic valve to fill the gas in the air cavity 104 into the cushion chamber 103 to expand and squeeze the wrist to achieve a reminder effect. At the same time, the micro air pump 105 extracts the gas in the cushion chamber 103 to the air cavity 104 after the reminder time ends. It can be used multiple times. An air pressure sensor 106 is arranged in the air cavity 104. The air pressure sensor 106 monitors the air pressure in the air cavity 104 in real time. The driving assistance wristband 1 is equipped with a voltage transmitter 107 and a current sensor 108 matched with the voltage transmitter 107. The voltage transmitter 107 sends a small voltage to the driver's body. The current sensor 108 monitors the driver's body current in real time and transmits the data to the detection module for analysis and collection; A pressure button 204 matched with the driving assistance wristband 1 is installed on the wristband fixing groove 201, and the pressure button 204 monitors in real time whether the driving assistance wristband 1 is fixed in the wristband fixing groove 201. An air outlet 206 is arranged on the steering wheel 205 of the cab 2, and the air outlet 206 is connected to an air pump 207. The input end of the air pump 207 is connected to an air storage tank 208 through an air pipe 215, and the air pump 207 is controlled to blow the gas in the air storage tank 208 out of the air outlet 206 through the air pipe 215, so as to achieve the effect of reminding the driver; The intelligent controller 3 is equipped with a display screen 301 and a buzzer 302. The buzzer 302 sounds an alarm to remind the driver when the driver drives dangerously. The display screen 301 displays vehicle and human information in real time. The intelligent controller 3 is provided with a control module, a monitoring module and an alarm module. The control module is electrically connected to the solenoid valve, the micro air pump 105, the voltage transmitter 107, the air pump 207 and the detection module respectively. The control module is used to control the reminder unit to remind the driver. The detection module is electrically connected to the piezoelectric sensor, the air pressure sensor 106, the current sensor 108 and the pressure button 204 respectively. The detection module is used to control the sensor to monitor the driver's driving status and the reminder unit status in real time. The alarm module is electrically connected to the buzzer 302 and the detection module respectively. The alarm module is used to control the buzzer 302 alarm to remind the driver.

[0020] It can be seen that the driving assistance wristband 1 is fixed by the wristband fixing groove 201. When the driving assistance wristband 1 is taken out, the pressure button 204 sends a signal to the detection module. The multiple piezoelectric sensors connected to the electrode glove 102 monitor the driver's body voltage in real time and transmit the data to the detection module for collection and analysis. At the same time, the voltage transmitter 107 sends a small voltage to the driver's body, and the current sensor 108 monitors the driver's body current in real time. If the detection module analyzes that the driver is driving dangerously, the control module controls the solenoid valve to fill the gas in the air cavity 104 into the soft cushion bin 103 to expand and squeeze the wrist. At the same time, the air pump 207 blows the gas in the air tank 208 out of the air outlet 206 through the air pipe 215 to achieve a reminder effect. After that, the micro air pump 105 extracts the gas in the soft cushion bin 103 to the air cavity 104. The air pressure sensor 106 monitors the air pressure in the air cavity 104 in real time during the reminder process to limit the amount of inflation, and the buzzer 302 simultaneously sends an alarm to remind, and the display screen 301 displays vehicle and human information in real time.

[0021] See also Figure 1 , Figure 6 and Figure 7 A seat 209 is installed in the cab 2, and a safety belt opening 210 is installed on the seat 209. A telescopic component is provided at the connection between the safety belt opening 210 and the seat 209. The protrusion of the safety belt opening 210 is controlled by the telescopic component to achieve a reminder effect. The telescopic component includes a telescopic motor 211 installed on the seat 209 and a fixed plate 212 installed at the output end of the telescopic motor 211. The fixed plate 212 is fixed to the safety belt opening 210. The control module is electrically connected to the telescopic motor 211. The control module controls the telescopic motor 211 to control the fixed plate 212 to carry the safety belt opening 210 to protrude from the seat 209 and squeeze the driver to remind him.

[0022] See also Figure 2A spring 202 is installed on the wristband fixing groove 201, and the spring 202 is used to apply force to the fixing buckle 203 to squeeze the driving assistance wristband 1 for fixing. The spring 202 is connected to a fixing buckle 203 that matches the driving assistance wristband 1 and is used to fix the driving assistance wristband 1.

[0023] See also Figure 4 The bottom of the air tank 208 is connected to an air charging pipe 216, on which a filter 217 is installed. The other end of the air charging pipe 216 passes through the outside of the cab 2. The gas outside the cab 2 is filtered by the filter 217 installed on the air charging pipe 216 and then input into the air tank 208 for blowing reminder.

[0024] In summary, before driving the vehicle, the driver first takes out the driving assistance wristband 1 from the fixing buckle 203 set in the wristband fixing groove 201 and puts it on. The pressure button 204 installed on the wristband fixing groove 201 detects that the driving assistance wristband 1 has been taken out before starting the car. After putting on the driving assistance wristband 1 and putting on the electrode glove 102 placed in the storage compartment, the tiny voltage applied by the voltage transmitter 107 forms a closed circuit with the human body. At the same time, the multiple piezoelectric sensors connected to the electrode glove 102 monitor the driver's body voltage in real time. The driving assistance wristband 1 The current sensor 108 installed on the ring 1 monitors the driver's body current in real time and transmits the data to the detection module for analysis and collection. If the driver's heart rate is judged to be too high after analysis, it is determined that the driver is anxious and fatigued when driving. The control module controls the solenoid valve to fill the gas in the air cavity 104 into the cushion chamber 103 to expand and squeeze the wrist. At the same time, the air pump 207 blows the gas in the air tank 208 out of the air outlet 206 through the air pipe 215 to achieve a reminder effect. The control module controls the telescopic motor 211 to control the fixing plate 212 to protrude with the safety belt mouth 210 The seat 209 squeezes the driver to remind him, and the micro air pump 105 extracts the gas in the cushion chamber 103 to the air cavity 104 after the reminder time ends. It can be used multiple times. The air pressure sensor 106 monitors the air pressure in the air cavity 104 in real time. If the air pressure is detected to be reduced to the minimum air pressure value during inflation (the minimum air pressure value of the air cavity 104 after the cushion chamber 103 is inflated and reminded in the control module), it is determined that the expansion degree of the cushion chamber 103 has reached the reminder effect. If the air pressure is detected to be increased to the maximum air pressure value (the minimum air pressure value of the air cavity 104 in the control module) during air extraction The maximum pressure of the storable gas is reached), then it is determined that the cushion compartment 103 has retracted to the normal state, and control will be suspended. During the reminder process, the display screen 301 will display the vehicle and human body information in real time, and the buzzer 302 will simultaneously sound an alarm for reminder. The gas outside the cab 2 can also be filtered through the filter 217 installed on the inflation pipe 216 and then input into the air storage box 208 for blowing reminders, which reduces costs and can ensure the health and safety of the driver in advance after filtering. The reminder process reduces the risk of frightening the driver and causing accidents caused by dangerous driving.

[0025] The second implementation method: Figure 1 and Fig. 9 An intelligent reminder device for assisting vehicle driving is shown. Different from the first embodiment, a face detector 218 is installed on the top of the inner cavity of the cab 2. The face detector 218 is installed on the top of the inner cavity of the cab 2 so as not to affect the driver's driving sight. An eye movement sensor 219 and a speed sensor 222 are installed on the face detector 218. The detection module is electrically connected to the eye movement sensor 219 and the speed sensor 222 respectively. The eye movement sensor 219 monitors the driver's eye movement frequency in real time. If the eye movement frequency decreases and remains for a long time, it is determined that the driver is distracted and has dangerous driving behavior. The control module controls the air pump 207 to blow the gas in the air tank 208 out of the air outlet 206 through the air pipe 215 to achieve the effect of preliminary reminder. If the eye movement frequency is still in an abnormal state, the control module controls the driving assistance bracelet 1 and the telescopic motor 211 to remind the driver, and the buzzer 302 issues an alarm until the driver data is normal. The speed sensor 222 monitors the driver's driving speed in real time. If the driving speed decreases steadily for a long time, it is preliminarily determined that the driver is driving abnormally, and the control module controls the reminder unit to remind the driver.

[0026] See also Figure 8 and Fig. 9 A tire pressure sensor 220 is provided at the connection between the steering wheel 205 and the cab 2, and a tire temperature sensor 221 is provided on the steering wheel 205. The detection module is electrically connected to the tire pressure sensor 220 and the tire temperature sensor 221 respectively. The tire pressure sensor 220 monitors the pressure on the steering wheel 205 in real time. If the detected pressure is too low, it is determined that the driver is distracted while driving and does not hold the steering wheel 205. The control module controls the reminder unit to remind the driver. The tire temperature sensor 221 monitors the temperature of the steering wheel 205 in real time. If the overall temperature of the steering wheel 205 is too low, the control module controls the reminder unit to remind the driver.

[0027] See also Figure 1 and Fig. 9 An oxygen sensor 223 is installed in the cab 2, the detection module is electrically connected to the oxygen sensor 223, a ventilator 224 is installed in the cab 2, the seat 209 is made of elastic high-strength material, the control module is electrically connected to the ventilator 224, the oxygen sensor 223 monitors the oxygen content in the cab 2 in real time, if the detected oxygen content drops to the limit value (the lowest value of the oxygen content in the cab 2 during normal driving in the detection module), it is determined that the oxygen content in the cab 2 is scarce, and hypoxia is prone to occur, affecting normal driving, and the control module controls the ventilator 224 to ventilate the cab 2 and provide oxygen.

[0028] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection.
