The steering wheel is a vehicle part which is contacted by a driver in a driving process, and the driver needs to put both hands on the steering wheel all the time when driving a car, so that the state of the driver is detected by arranging a corresponding detection device on the steering wheel, and the state detection method is simple and effective. Referring to fig. 1, a steering wheel 1 with a detection function is shown, where the steering wheel 1 includes: a central seat 11, spokes 12 and a rim 13. A sweat sensor 14 and a heart rate sensor 15 are provided at specific locations on the rim 13 to enable detection of the driver's condition. When the driver places both hands at the sweat sensor 14 and heart rate sensor 15, the sweat sensor 14 and heart rate sensor 15 can detect information about the driver. However, the steering wheel 1 cannot monitor the state of the driver when the driver places both hands at other positions of the steering wheel. In addition, the driving habits of different drivers are different, the positions of the drivers for gripping the steering wheel are different, the steering wheel 1 cannot meet the requirements of different drivers, and the universality is poor. To solve this problem, the present invention provides a monitoring steering wheel including: a center seat; a rim, on which a groove is arranged; the spoke is respectively connected with the central seat and the rim; a contact detection portion provided on a surface of the rim for detecting a position where a driver grips a steering wheel; the state monitoring part is arranged in the groove, can move relative to the groove and is used for monitoring the state of a driver; and the control processing part is in communication connection with the contact detection part and the state monitoring part and is used for controlling the state monitoring part to move to the position where the driver grasps the steering wheel. The monitoring steering wheel comprises a contact detection part for detecting the gripping position and a movable state monitoring part, so that the state monitoring part is always positioned at the position where a driver grips the steering wheel, and the state of the driver can be continuously monitored.
In an embodiment of the present invention, please refer to fig. 2, which shows a left side view of the monitoring steering wheel 2 according to the embodiment; referring to fig. 3, a cross-sectional view of a-a' of the monitoring steering wheel 2 according to the present embodiment is shown; referring to fig. 4, a cross-sectional view of the monitoring steering wheel 2 of the present embodiment is shown. The monitoring steering wheel 2 includes:
a center seat 21; the rim 23 is provided with a groove 231; spokes 22 connected to the central seat 21 and the rim 23, respectively; the central seat 21, the spokes 22 and the rim 23 together constitute the main body of the steering wheel;
a contact detection portion 24 provided on a surface of the rim 2 for detecting a position where a driver grips a steering wheel;
a state monitoring part 25 disposed inside the groove 231 and movable relative to the rim 23 for monitoring a state of a driver;
and a control processing portion, which is connected in communication with the contact detecting portion 24 and the state monitoring portion 25, for controlling the state monitoring portion to move to a position where the driver grips the steering wheel.
In the present embodiment, the contact detection portion 24 detects the position where the driver grips the steering wheel when the driver grips the steering wheel, and then sends the position to the control processing portion; the control processing portion controls the state monitoring portion 25 to move to a position where the driver grips the steering wheel and monitors the state of the driver.
When the driver changes the position of gripping the steering wheel for a turn or the like, the contact detection portion 24 detects the changed gripping position of the driver and sends the position to the control processing portion, which controls the state monitoring portion 25 to move to the changed gripping position of the driver and detects the state of the driver. In this embodiment, two state monitoring portions 25 may be provided to monitor the states of both hands of the driver, respectively; only one state monitoring portion 25 may be provided for monitoring the state of any one hand of the driver; preferably, the one condition monitoring portion 25 moves to the driver's left hand position for monitoring.
In an embodiment of the present invention, the control processing unit is disposed on a center console of the vehicle, and is connected to the contact detecting unit 24 and the state monitoring unit 25 through a CAN bus, respectively, and mainly functions to control the state monitoring unit 25 to move to a position where a driver currently grips a steering wheel according to a detection result of the contact detecting unit 24. The control of the control processing part to the motion of the state monitoring part can be realized by a control circuit of an unmanned aerial vehicle or a remote control car in the prior art, and the specific realization method is not repeated here.
In an embodiment of the present invention, the state monitoring unit 25 includes: a sensor 251 disposed in the recess 213 for monitoring the state of the driver; and the movement supporting piece 252 is arranged in the groove 213, is in communication connection with the control processing part, and is used for fixing the sensor and driving the state monitoring part to move.
In one embodiment of the present invention, the groove 213 is convex and includes a groove opening 2311 and a groove cavity 2312. In this embodiment, the sensor 251 is disposed in the notch 2311, and collects the status information of the driver through the notch 2311. The moving support 252 is located in the groove cavity 2312, is connected with the cavity wall of the groove cavity 2312 in a sliding and/or rolling manner, and is fixedly connected with the sensor 251. The moving support 252 can rotate around the groove 2312 to move the sensor 251 to a position where the driver grips the steering wheel.
Referring to fig. 5, in an embodiment of the present invention, teeth 232 are disposed inside the groove; the moving support 252 includes: a support 2521 disposed in the groove 231 and fixedly connected to the sensor 251; a gear 2522 provided on the support body 2521 to be engaged with the teeth 232 inside the groove 231; and the motor is arranged on the support body 2521, is in communication connection with the control processing part, and drives the gear to rotate through an output shaft.
In this embodiment, the motor can drive the gear 2522 to rotate, and the output shaft of the motor can be fixedly connected to the center of the gear 2522. In this embodiment, when the driver grips the steering wheel or the position where the driver grips the steering wheel changes, the contact detection portion 24 detects the position where the driver currently grips the steering wheel and sends the position to the control processing portion. Thereafter, the control processing portion activates the motor, which drives the gear 2522 to rotate and drives the state monitoring portion 25 to move to a position where the driver currently grips the steering wheel. When the gear 2522 is rotated to a position where the driver currently grips the steering wheel, the control processor controls the motor to stop operating, at which time the output shaft of the motor no longer rotates and the gear 2522 stops moving. The moving support is fixed in the position where the driver is currently gripping the steering wheel due to the intermeshing of gear 2522 and teeth 232. In order to accurately fix the motion support piece at the position where the driver currently grasps the steering wheel, the motor is preferably a band-type brake motor. The band-type brake motor is a motor which can quickly lock an output shaft when the motor stops so as to prevent the motor from continuously moving, and common band-type brake modes comprise a mechanical band-type brake, an electrical band-type brake and the like.
In this embodiment, the function of the control processing unit controlling the motor to start or stop may be implemented by using an existing motor remote control circuit and method, which are not described herein again.
In an embodiment of the present invention, the sensor 251 includes: a photoelectric heart rate sensor 2511 which is connected with the control processing part in a communication way and is used for monitoring the heart rate of the driver; an infrared body temperature sensor 2512 which is in communication connection with the control processing part and is used for monitoring the body temperature of the driver; and a photoelectric blood pressure sensor 2513 which is in communication connection with the control processing part and is used for monitoring the blood pressure of the driver.
The photoelectric heart rate sensor 2511, the infrared body temperature sensor 2512 and the photoelectric blood pressure sensor 2513 are all non-contact sensors, and the parameters of the heart rate, the body temperature, the blood pressure and the like of a driver can be measured without contacting with a human body in the measurement process. In this embodiment, the sensor 251 can perform non-sensory measurement, and can transmit the measured data to the control processing unit for analysis so as to determine the current state of the driver. For example, when the sensor 251 detects that the heart rate, the body temperature or the blood pressure of the driver is abnormal, the control processing part can determine that the current state of the driver is not suitable for driving according to the information, so that corresponding measures can be taken in time to avoid danger. The photoelectric heart rate sensor, the infrared body temperature sensor and the photoelectric blood pressure sensor can be realized by adopting the existing sensors, and the size and the shape of the corresponding sensor are properly adjusted and are connected with the control processing part in a communication way in practical application.
In an embodiment of the present invention, the photoelectric heart rate sensor 2511, the infrared body temperature sensor 2512, and the photoelectric blood pressure sensor 2513 sequentially monitor the status information of the driver in a time slice rotation manner.
In this embodiment, in order to avoid mutual interference among the photoelectric heart rate sensor 2511, the infrared body temperature sensor 2512, and the photoelectric blood pressure sensor 2513, the three devices operate in a time slice rotation manner, for example: the photoelectric heart rate sensor 2511 works for 30 seconds, the infrared body temperature sensor 2512 works for 30 seconds, and the photoelectric blood pressure sensor 2513 works for 30 seconds, so that one cycle is completed. Thereafter, the photoelectric heart rate sensor 2511 operates and begins the next cycle.

A pressure sensor is a device or apparatus that can sense a pressure signal and can convert the pressure signal into a usable output electrical signal according to a certain rule, and generally comprises a pressure sensitive element and a signal processing unit. Because a plurality of pressure sensors are distributed at different positions on the surface of the rim, when a user grasps the steering wheel, the pressure sensors at corresponding positions detect pressure and feed back the pressure to the control processing part, and the control processing part determines the current position of grasping the steering wheel by the driver according to the position of the pressure sensors. The response time of the pressure sensor is mostly in the millisecond level, so that the pressure sensor can monitor the position where the driver grasps the steering wheel and the change of the grasping position of the driver in real time.
In an embodiment of the present invention, the contact detecting portion includes: the base plate covers the surface of the rim; the first conductive wire layer is arranged on the surface of the substrate; the first isolating layer covers the surface of the first conductive silk layer; the second conductive wire layer is arranged on the surface of the first isolation layer; the second isolating layer covers the surface of the second conductive silk layer; and the protective layer covers the surface of the second isolation layer.
The first conductive wire layer is composed of insulated conductive wires laid continuously along the X-axis direction, and the second conductive wire layer is composed of insulated conductive wires laid continuously along the Y-axis direction. When the driver grips the steering wheel, the capacitance of the human body is superimposed on the circuit of the contact detection portion, resulting in a change in the capacitance of the circuit in the contact detection portion. The current position of the driver gripping the steering wheel can be confirmed according to the change condition of the capacitance.

The mylar layer 241 is an elastic material, and the first ITO layer 244 and the second ITO layer 242 are separated when the driver does not grip the steering wheel. Referring to fig. 6B, when the driver grasps the steering wheel, the mylar layer 241 at the corresponding position deforms downward and makes the second ITO layer 242 contact the first ITO layer 241, so that the circuit is turned on, and the position where the driver grasps the steering wheel currently can be determined according to the turned-on position of the circuit.
