[0023] The driver holds the steering wheel 1 with both hands, the pressure of the hands makes the contact grooves 5 on the conductive ring 4 closely contact with the electric needles 7 on the electric contact ring 6, because the electric needles 7 and the contact grooves 5 are matched, when the contact occurs, a closed circuit is formed in the inside of the steering wheel 1, at this time, because the indicator 2, the drying mechanism 3 and the conductive ring 4 and the electric contact ring 6 are electrically connected, the indicator 2 is started immediately after receiving the circuit closing signal, and the indicator 2 directly indicates the driver by means of lighting, so that the driver clearly knows that the current hand position state is normal, at the same time, the air outlet assembly starts to work, the outside air enters the inside of the equipment through the air direction adjusting port 32 on both sides of the equipment shell 31, the conductive ring 4 is in the form of a ring and the contact grooves 5 are uniformly distributed on the conductive ring 4, which can ensure that no matter where the driver's hand presses on the steering wheel 1, the closed circuit will be triggered, and the reset spring arranged in the inside of the contact groove 5 plays a role when the driver's hand leaves the steering wheel 1, the elastic restoring force of the reset spring makes the contact groove 5 return to the initial state, the electric needle 7 is separated from the contact groove 5, the circuit is disconnected, the indicator 2 stops lighting indication, and the air outlet assembly stops working, so that the hand-off monitoring process is completed.
[0024] Embodiment two:
[0025] Please refer to Figures 1 to 4The embodiment provides a technical scheme based on the embodiment one: the air-drying mechanism 3 comprises a device shell 31, the two sides of the device shell 31 are respectively provided with air direction adjusting openings 32 for adjusting the air direction, and the two sides of the steering wheel 1 are provided with matched air outlets 33, so that the air blows the driver's hands when the closed circuit is formed by the conductive ring 4 and the power connection ring 6, the air-drying mechanism 3 further comprises a pressure nozzle 34 arranged in the air outlet 33, and the bottom of the device shell 31 is detachably connected with a device base 35, the inside of the device base 35 is provided with a placing groove 37 for bacteriostatic agent, so that the bacteriostatic agent is sprayed from the pressure nozzle 34 when the air outlet assembly is started, the two sides of the device base 35 are fixedly connected with fixing buckles 36, and the bottom of the device shell 31 is provided with a clamping groove matched with the fixing buckles 36, so that the device shell 31 and the device base 35 are engaged and fixed;
[0026] When the driver holds the steering wheel 1 with both hands to form a closed circuit of the conductive ring 4 and the power connection ring 6, the air direction adjusting openings 32 guide the entering air to blow out from the air outlets 33 on the two sides of the steering wheel 1 through the internal passages, the air direction directly points to the driver's hands, accelerates the evaporation of the hand sweat, keeps the hands dry, improves the driving comfort and reduces the interference of the sweat on the equipment detection, meanwhile, the bottom of the device shell 31 is connected with the device base 35 in a clamping and fixing mode of the fixing buckles 36 and the clamping grooves, the bacteriostatic agent in the placing groove 37 in the device base 35 is pushed to the pressure nozzle 34 in the air outlet 33 along the pipeline under the action of the pressure generated by the air outlet assembly, is sprayed from the nozzle together with the airflow, is evenly sprinkled on the driver's hands, and the growth of bacteria on the hands is inhibited, when the driver's hands are away from the steering wheel 1 and the circuit is disconnected, the indicator 2 stops lighting as described in the embodiment one, the air-drying mechanism 3 stops the air outlet and the bacteriostatic agent spraying operation, and the whole system completes a complete working cycle, continuously guarantees the safety and hygiene in the driving process.
[0027] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.
[0028] Working principle: when the driver normally holds the steering wheel 1, the pressure applied by the hands makes the contact groove 5 on the conductive ring 4 and the electric needle 7 on the contact ring 6 come into contact with each other, thereby forming a closed circuit. At the moment when the circuit is closed, the indicator 2 connected to the circuit receives an electrical signal, and the light circuit inside the indicator is turned on, the indicator light is on, and the driver is visually displayed in a direct way that the hands are in the correct position on the steering wheel, providing visual feedback for the driver. At the same time, the air outlet assembly fixed inside the steering wheel 1 is started synchronously, and the outside air enters the device inside under the guidance of the air direction adjusting port 32 set on both sides of the device shell 31, then flows along the pre-designed internal channel, and finally blows out from the air outlet 33 matched with the steering wheel 1 on both sides, accurately blowing to the driver's hands. The rapid flow of air accelerates the evaporation process of hand sweat, effectively keeps the hands dry, and reduces the influence of sweat on the steering wheel control and detection function. During the operation of the air outlet assembly, the bacteriostatic agent pre-placed in the placing groove 37 inside the device base 35 is pushed to the pressure jet head 34 set inside the air outlet 33 under the pressure generated by the air outlet. When the airflow passes through the pressure jet head 34, the bacteriostatic agent is carried out from the jet head in the form of fine mist, uniformly falling on the driver's hands, reducing the risk of bacterial growth on the hands, and further improving the hygiene of the driving environment, providing a more comfortable and healthy driving experience for the driver. When the driver's hands leave the steering wheel 1 for various reasons, the reset spring installed inside the contact groove 5 restores the contact groove 5 to the initial position by virtue of its elastic restoring force, and the originally contacted electric needles 7 are separated from the contact groove 5, so that the circuit is disconnected. After the circuit is disconnected, the light circuit inside the indicator 2 stops working due to the loss of electrical signal, and the indicator light is turned off, no longer showing the state of the hands on the steering wheel. At the same time, the air drying mechanism 3 also stops running, and the whole system completes a complete hand-off monitoring cycle. After the driver holds the steering wheel again, the system will repeat the above working process, continuously monitoring the contact state between the driver's hands and the steering wheel, ensuring the safety of the driving process in real time, and effectively reducing the safety risks that may be caused by the hands off.
