Electric buses have good power performance, a continuous driving range of 500 kilometers, a long battery life (more than two years), low cost, and are well-matched with the entire vehicle. They can achieve the diversification of the transportation energy structure, maintain national energy security, reduce automobile emission pollution, ensure sustainable social development, improve the independent innovation capability of my country's automobile industry, and achieve leapfrog development of the automobile industry.

[0003] When driving electric buses, some drivers may experience fatigue driving, which can easily cause accidents.

However, it is impossible to remind the driver who dozes off during driving, and it is impossible to effectively stimulate the driver to make him awake and excited, which puts the safety of the people on the bus in danger and increases the accident rate. Summary of the invention

[0019] Through the above technical scheme, after the rotating friction plate and the adjusting friction disk are plugged into contact, the rotation of the adjusting friction disk can drive the rotating friction plate to rotate, and the rotation of the rotating friction plate can drive the rotating turntable to rotate, and then drive the camera to turn. The telescopic friction plate and the adjusting friction disk are slidingly plugged in, and the rotation of the adjusting friction disk can drive the telescopic friction plate to rotate, and drive the driving bevel gear to rotate, thereby driving the inner telescopic sleeve to move.

[0020] Preferably, the upper surface of the connecting frame is rotatably connected to a rotating bevel gear ring with a column through a bearing, the rotating bevel gear ring is meshed with the driving bevel gear, the outer surface of the inner telescopic sleeve is slidably inserted with an outer telescopic sleeve, the lower surface of the outer telescopic sleeve and the lower surface of the inner telescopic sleeve are both slidably inserted with the connecting column of the connecting frame, the outer surfaces of the outer telescopic sleeve and the inner telescopic sleeve are both provided with arc grooves, the inner walls of the two arc grooves are slidably inserted with the columns of the rotating bevel gear ring in turn, one end of the outer telescopic sleeve is fixedly installed with one end of the camera, and a sealing block is fixedly installed at one end of the inner telescopic sleeve.

At the same time, the spraying nozzle can be rotated in the conveying connecting seat to adjust the direction of the spray, so that it is convenient to face the driver's face when spraying the aromatherapy liquid. The connecting joint can connect one end of the water storage airbag with one end of the ultrasonic atomizing nozzle.

[0024] Preferably, the extrusion mechanism also includes a micro electric push rod, which is fixedly mounted on the inner wall of the steering wheel of the bus, and a lifting frame is fixedly mounted on one end of the piston rod of the micro electric push rod, and an adjusting rack is slidably inserted into the outer surface of the lifting frame, and the outer surface of the lifting frame is rotatably connected to a transmission gear through a bearing, and the two adjusting racks are respectively meshed with the upper surface and the lower surface of the transmission gear, and one end of the adjusting rack is rotatably connected to one end of the extrusion roller through a bearing.

[0025] Through the above technical scheme, the lifting frame can be pulled up by the micro electric push rod.

Through the combination of the strain gauge and the data collected by the camera, the driver's state is determined. After the voltage of the strain gauge gradually weakens and the camera captures the driver's slow blinking or closing of eyes for more than the set threshold, a voice reminder is given. The voice reminder is turned off by the driver. After the driver does not turn off the alarm module, the control push motor is started to generate vibration, and then the ultrasonic atomizing nozzle is controlled to spray water mist to remind the driver. Communication modules, security and encryption modules and navigation system interfaces can be added, and vehicle information and the driver's state can be transmitted to the navigation system and the nearby police system, so as to remind surrounding vehicles and police, thereby reducing the occurrence of traffic accidents.

[0030] The beneficial effects of the present invention are: 1. By setting a touch device, the driver's grip on the bus steering wheel can be monitored, and the push plate can be limited by plugging between the plug rod and the plug sleeve. At the same time, the spring connected between the plug rod and the plug sleeve facilitates the resetting of the push plate. The driver can make the push plate contact the strain gauge by holding both sides of the bus steering wheel. After the strain gauge is deformed, a voltage signal is generated. The driver's support force on the bus steering wheel is judged by the strength of the voltage signal. When dozing off, the hand grip will continue to weaken, so it can be judged that the driver is dozing off. By starting the push motor, the push frame can be pushed back and forth to vibrate the driver's hand, thereby achieving the effect of reminding the driver. The existing pure electric bus fatigue driving reminder method generally uses voice reminders, but it is impossible to remind the driver who dozes off during driving, and it is impossible to effectively stimulate the driver to make him awake and excited, causing the safety of the people on the bus to be endangered and increasing the accident rate. Technical problems.

[0031] 2. By setting up an identification device, the driver's face can be monitored. At the same time, after the camera is turned, the front of the vehicle can be monitored. The camera is controlled to rotate or retract by a driving motor. After the rotating friction plate and the adjusting friction disk are plugged in and contacted, the rotation of the rotating friction plate can drive the rotating turntable to rotate, and then drive the camera to turn. The telescopic friction plate and the adjusting friction disk are slidably plugged in to drive the driving bevel gear to rotate, thereby driving the inner telescopic sleeve to move, so that the camera can be turned after shrinking and the position of the camera can be adjusted, so that the camera has two functions. When the camera is facing the outside of the vehicle, the position in front of the vehicle can be monitored, and the sealing block can seal the exposed hole at the other end to prevent dust from entering.

[0032] 3. By setting a reminder device, the driver can be reminded by spraying. When the water storage airbag needs to be placed, the outer squeezing roller is pulled outward to move, and the adjusting rack is driven to move. The transmission gear is rotated to drive the inner squeezing roller to move inward, so that the water storage airbag can be placed between the two squeezing rollers. After pushing the outer squeezing roller inward, the water storage airbag can be squeezed. The lifting frame is pulled up by the electric push rod to squeeze the water in the water storage airbag upward. At the same time, the rotating gear of the squeezing roller rotates under the action of the double-sided rack, so that the water in the water storage airbag is squeezed to the ultrasonic atomizing nozzle, which is convenient for the ultrasonic atomizing nozzle to atomize, so that the sprayed water mist is sprinkled on the driver's face for refreshing. The existing pure electric bus fatigue driving reminder method generally performs voice reminders, but cannot remind drivers who doze off during driving, and cannot effectively stimulate the driver to make him awake and excited, causing the safety of people on the car to be endangered and increasing the accident rate.

[0050] like Figure 2 As shown, in order to intelligently control the sensing device, the identification device and the reminder device, the main control module 12 is located inside the steering wheel 1 of the bus, and collects and analyzes the data collected by the strain gauge 26 and the camera 67.

[0051] The main control module 12 is composed of a signal conditioning module, a microcontroller module, a data acquisition module, an alarm module, an identification module and a storage module. The signal conditioning module is electrically connected to the strain gauge 26, the signal conditioning module is electrically connected to the data acquisition module, the data acquisition module is electrically connected to the microcontroller module, the alarm module is electrically connected to the microcontroller module, the identification module is electrically connected to the camera 67, the identification module is electrically connected to the microcontroller module, and the storage module is electrically connected to the microcontroller module.

[0052] The control main module 12 can process and analyze the data collected by the strain gauge 26 and the camera 67 to judge the driver's state. The driver's state is determined by combining the data collected by the strain gauge 26 and the camera 67. After the voltage of the strain gauge 26 gradually weakens and the camera 67 captures the driver's slow blinking or closing of the eyes for more than the set threshold, a voice reminder is given. The voice reminder is turned off by the driver. After the driver does not turn off the alarm module, the control push motor 32 is started to generate vibration, and then the ultrasonic atomizing nozzle 7 is controlled to spray water mist to remind the driver.

[0053] Working principle: When the driver is driving, he needs to hold both sides of the bus steering wheel 1 with both hands, so that he can press the pressing pieces 2 on both sides of the bus steering wheel 1 through the protective cover 11, and the pressing piece 2 moves toward the inside of the bus steering wheel 1, and the plug rod 21 moves in the plug sleeve 22, and the connecting spring 23 in the plug sleeve 22 is stretched. One end of the pressing piece 2 moves on the support frame 24, squeezing the reset spring 25, and one end presses the strain gauge 26. The generated voltage is amplified, filtered, and other processes are performed on the transmitted voltage signal by the signal conditioning module in the general control module to enhance the signal, and then the conditioned analog signal is converted into a digital signal through the data acquisition module, and the data transmitted by the data acquisition module is received by the microprocessor module for analysis and processing, and can be stored in the storage module for preservation; The camera 67 monitors the driver's face. When the driver becomes drowsy, the grip of the hand on the steering wheel 1 of the bus will continue to weaken, the force received by the strain gauge 26 will decrease, and the camera 67 captures the driver's slow blinking or closing of eyes. The camera 67 transmits the collected data to the recognition module for judgment. After the driver's slow blinking or closing of eyes exceeds the set threshold, the microprocessor module controls the alarm module to start and gives a voice reminder to the driver. When the driver fails to turn off the voice within the set time, the microprocessor module controls the push motor 32 to start, which drives the rotation of the cam 33. The cam 33 squeezes the push frame 3 to move, and the column on the push frame 3 can pass through the pressing sheet 2 to squeeze the protective cover 11. The shock-absorbing spring 31 is repeatedly compressed and reset, which can push the driver's hand while generating vibration to remind the driver. Then, the micro electric push rod 8 is controlled to pull the lifting frame 81 to rise, and the lifting frame 81 is driven to rise. The rotating gear 85 on the squeezing roller 84 moves on the double-sided rack 86, and can drive the two squeezing rollers 84 to rotate in the opposite direction. After squeezing the refreshing liquid in the water storage air bag 74, the refreshing liquid is atomized by the ultrasonic atomizing nozzle 7, and then enters the spraying nozzle 72 through the conveying connection seat 71 and sprays to the driver's face to remind the driver; When the water storage airbag 74 needs to be placed, the protective door panel 87 is opened, and the outer squeezing roller 84 is pulled outward to drive the adjustment rack 82 to move, and the transmission gear 83 is rotated to drive the inner squeezing roller 84 to move inward, so that the water storage airbag 74 is placed between the two squeezing rollers 84. After the outer squeezing roller 84 is pushed inward, the water storage airbag 74 can be fixed; When it is not necessary to drive the car and the camera 67 is needed to monitor the status in front of the car, the driving motor 4 is started to drive the adjusting friction disc 41 to rotate. At the same time, the adsorption electromagnet 44 located above is energized to adsorb the deflection frame 42. After the tower spring 43 is stretched, the deflection frame 42 lifts the adjusting friction disc 41. After the adjusting friction disc 41 can be plugged with the telescopic friction plate 62 above, the rotation of the adjusting friction disc 41 drives the telescopic friction plate 62 to rotate, drives the driving bevel gear 61 to rotate, drives the rotating bevel gear ring 63 to rotate through the transmission of the driving bevel gear 61, and after the column on the rotating bevel gear ring 63 is slidably plugged, the outer telescopic sleeve 65 and the inner telescopic sleeve 64 are pulled to move relative to each other, and then the camera 67 and the sealing block 68 are retracted into the steering wheel 1 of the bus; After the upper adsorption electromagnet 44 is powered off, the lower adsorption electromagnet 44 is powered on, the deflection frame 42 is deflected downward, the tower spring 43 is compressed, and the lower end of the friction disc 41 is adjusted to be plugged into the rotating friction plate 51 below, driving the rotating friction plate 51 to rotate in the store, driving the rotating turntable 5 to rotate, and after driving the connecting frame 6 to rotate, the inner camera 67 is turned to the outside of the bus steering wheel 1, so as to monitor the front of the bus.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
