Description

Technical Field

[0001] The invention belongs to the technical field of automobile electronic systems, and in particular relates to a region dividing device and a distraction warning system. Background Art

[0002] In the field of modern transportation, driving safety has always been a focus of great concern. With the popularization of vehicles and the increasing busyness of road traffic, driver distraction has become one of the important factors leading to traffic accidents.

[0003] Traditional driving safety mainly relies on the constraints of traffic laws and the self-consciousness of drivers. However, it is often difficult to completely eliminate distracted driving behavior by relying solely on these means. For example, during long driving, drivers may be distracted by fatigue, making phone calls, checking navigation, etc., which increases the risk of accidents.

[0004] In response to the above problems, the relevant technology proposes a distraction warning system, which can issue a warning in time after detecting that the driver's line of sight deviates from the safe driving area for a long time. However, the current technology still lacks a device that can quickly and accurately divide area 1, area 2, and area 3. Specifically, in actual driving scenarios, different areas may represent different safety levels or functional requirements. For example, area 1 may be the core safety area for vehicle driving, area 2 may be the surrounding warning area, and area 3 may be a relatively distant observation area. However, due to the lack of an effective area division device, it is often difficult to clearly distinguish these different areas, which limits the actual application effect of the distraction warning system.

[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] An embodiment of the first aspect of the present invention provides a region dividing device, and an embodiment of the second aspect of the present invention provides a distraction warning system.

[0040] Among them, the area division device is applied to the distraction warning system. Specifically, the area division device is used to quickly and accurately divide different driver's gaze areas, providing clear and definite area definitions for distraction warning system testing.

[0041] Specifically, when the area division device is applied to the distraction warning system, the distraction warning system can more accurately monitor whether the driver's line of sight deviates from the safe driving area based on the clear area definition determined by the area division device, thereby providing strong protection for the driver's safe travel.

[0042] See also Figure 1 and Figure 2 As shown, the area division device provided by the embodiment of the first aspect of the present invention includes: an optical indicator 1, which is set at the position of the driver's eye point and is used to emit a laser beam; a first rotation adjustment mechanism 2, which is connected to the optical indicator 1 and is used to drive the optical indicator 1 to rotate in a vertical plane; and a second rotation adjustment mechanism 3, which is connected to the first rotation adjustment mechanism 2 and is used to drive the first rotation adjustment mechanism 2 and the optical indicator 1 to rotate in a horizontal plane.

[0043] In this embodiment, by setting the first rotation adjustment mechanism 2 and the second rotation adjustment structure, the optical indicator 1 located at the driver's eye point can rotate freely in the vertical plane and the horizontal plane, and the laser beam can be quickly adjusted to the optimal angle, thereby accurately dividing area 1, area 2, and area 3.

[0044] It should be noted that Area 1 is the overlapping part of the following areas. One is the roof area; the other is any area in the vehicle outside the two vertical planes (with the direction the driver is looking straight ahead as 0°, one plane is 55° to the right relative to the longitudinal direction of the vehicle, and the other plane is 55° to the left relative to the longitudinal direction of the vehicle, and the two planes intersect at the driver's eye point). Area 2 consists of two parts. One is the area of ​​the windshield and windows; the other is the range of 10° around the windshield and windows area from the driver's eye point. Area 3 is any area below the plane 30° downward from the driver's eye point and outside Area 1 and Area 2.

[0045] The optical indicator 1 is arranged at the position of the driver's eye point, so that the position of the optical indicator 1 corresponds to the position of the driver's eyes, so as to better simulate the driver's sight direction.

[0046] Specifically, the optical indicator 1 can be a small laser emitter, a miniature LED spotlight, or a light-emitting diode with a special optical lens, etc., which is not limited in the present invention. In practical applications, the optical indicator 1 is used to emit a laser beam to form an obvious light mark around the vehicle, thereby realizing the division of different areas.

[0047] Among them, the first rotation adjustment mechanism 2 can be a gear-driven rotation adjustment mechanism, a worm-wheel type rotation adjustment mechanism, a connecting rod type rotation adjustment mechanism or a ball-joint type rotation adjustment mechanism. For example, the first rotation adjustment mechanism 2 is a gear-driven rotation adjustment mechanism, which is composed of a driving gear, a driven gear and a driving motor. The driving gear is connected to the driving motor, the driven gear is fixedly connected to the optical indicator 1, and the driving gear and the driven gear are meshed with each other. The driving motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate through meshing transmission, so that the optical indicator 1 rotates in the vertical plane. The rotation angle of the optical indicator 1 can be accurately adjusted by controlling the speed and direction of the driving motor; the first rotation adjustment mechanism 2 is a worm-wheel type rotation adjustment mechanism, including a worm wheel, a worm and an adjustment knob. The worm wheel is connected to the optical indicator 1, and the worm is manually or electrically driven by the adjustment knob. Turning the adjustment knob causes the worm to drive the worm wheel to rotate, thereby realizing the rotation of the optical indicator 1 in the vertical plane. The worm gear transmission has a large transmission ratio and self-locking performance, which can ensure that the optical indicator 1 remains stable after being adjusted to a specific angle; the first rotation adjustment mechanism 2 is a connecting rod type rotation adjustment mechanism, which is composed of multiple connecting rods and electric push rods. The connecting rods are connected to each other to form a deformable frame, the optical indicator 1 is installed on the frame, and the electric push rod is connected to a specific position of the frame. The telescopic movement of the electric push rod pushes the connecting rod frame to deform, so that the optical indicator 1 rotates in the vertical plane. By controlling the stroke and speed of the electric push rod, the rotation angle of the optical indicator 1 can be accurately adjusted; the first rotation adjustment mechanism 2 is a ball joint type rotation adjustment mechanism, including a ball joint seat and an adjusting bolt. The optical indicator 1 is connected to the ball joint seat through a ball joint, and the adjusting bolt is used to adjust the tightness of the ball joint. By tightening or loosening the adjusting bolt, the friction of the ball joint can be changed, so that the optical indicator 1 can rotate freely in the vertical plane or be fixed at a specific angle. This rotation adjustment mechanism has a simple structure and is easy to operate.

[0048] Among them, the second rotation adjustment mechanism 3 can be a ring track type rotation adjustment mechanism, a pulley drive type rotation adjustment mechanism, a magnetic suspension rotation adjustment mechanism or a harmonic gear drive type rotation adjustment mechanism. For example, the second rotation adjustment mechanism 3 is a ring track type rotation adjustment mechanism, which includes a ring track, a slider and a drive motor. The slider is installed on the ring track and connected to the first rotation adjustment mechanism 2 and the optical indicator 1, and the drive motor drives the slider to move on the ring track. The drive motor drives the slider to rotate on the ring track, so that the first rotation adjustment mechanism 2 and the optical indicator 1 connected to the slider rotate in the horizontal plane. The horizontal rotation angle of the optical indicator 1 can be accurately adjusted by accurately controlling the rotation angle of the motor; the second rotation adjustment mechanism 3 is a pulley drive type rotation adjustment mechanism, which is composed of a driving pulley, a driven pulley, a transmission belt and a motor. The driving pulley is connected to the motor, the driven pulley is connected to the first rotation adjustment mechanism 2, and the transmission belt connects the two pulleys. The motor drives the driving pulley to rotate, and the driven pulley is driven to rotate through the transmission belt, thereby rotating the first rotation adjustment mechanism 2 and the optical indicator 1 in the horizontal plane. The horizontal rotation speed and direction of the optical indicator 1 can be controlled by adjusting the speed and direction of the motor; the second rotation adjustment mechanism 3 is a magnetic suspension rotation adjustment mechanism, including a magnetic suspension base, a rotating component and an electromagnetic control system. The first rotation adjustment mechanism 2 and the optical indicator 1 are installed on the rotating component, and the magnetic suspension base supports and controls the rotation of the rotating component through electromagnetic force. The electromagnetic control system adjusts the intensity and direction of the magnetic field to make the rotating component rotate freely in the horizontal plane. This rotation adjustment mechanism has the characteristics of friction-free and high precision, and can achieve very smooth and accurate horizontal rotation adjustment; the second rotation adjustment mechanism 3 is a harmonic gear transmission type rotation adjustment mechanism, which consists of a rigid wheel, a flexible wheel and a wave generator. The wave generator is connected to the motor, the flexible wheel is connected to the first rotation adjustment mechanism 2, and the rigid wheel is fixed. The motor drives the wave generator to rotate, so that the flexible wheel produces elastic deformation, thereby realizing the rotation of the first rotation adjustment mechanism 2 and the optical indicator 1 in the horizontal plane. Harmonic gear transmission has the advantages of large transmission ratio, high precision, small size, etc., and is suitable for occasions with high space requirements.

[0049] Specifically, the process of the area division device to realize the division of area 1 is as follows: first, with the direction of the driver looking straight ahead as a reference, the angle of the optical indicator 1 is first adjusted in the horizontal plane by the second rotation adjustment mechanism 3 so that it roughly points to the longitudinal front of the vehicle. Then, the optical indicator 1 is fine-tuned in the vertical plane by the first rotation adjustment mechanism 2 to ensure that the laser beam can cover the roof area and the area outside the two vertical planes in the vehicle. The two vertical planes are 0° in the direction of the driver looking straight ahead, one plane is 55° to the right relative to the longitudinal direction of the vehicle, and the other plane is 55° to the left relative to the longitudinal direction of the vehicle, and the two planes intersect at the driver's eye point. By continuously adjusting the two adjustment mechanisms, the laser beam accurately outlines the boundary of area 1; the process of the area division device to realize the division of area 2 is as follows: first, the optical indicator 1 is rotated in the horizontal plane by the second rotation adjustment mechanism 3 so that its laser beam can cover the area of ​​the windshield and the window. Then, the first rotation adjustment mechanism 2 is used to make fine adjustments in the vertical plane to ensure that from the driver's eye point, the 10° range around the windshield and the window area can also be accurately covered by the laser beam. By repeatedly adjusting the two adjustment mechanisms, the division of area 2 is ensured to be accurate; the process of the area division device to achieve the division of area 3 is as follows: first, the optical indicator 1 is adjusted downward in the vertical plane by the first rotation adjustment mechanism 2, so that its laser beam points to the area below the plane 30° downward from the driver's eye point. Then, the optical indicator 1 is rotated in the horizontal plane by the second rotation adjustment mechanism 3 to ensure that the area is outside area 1 and area 2. The two adjustment mechanisms are continuously adjusted to make the laser beam clearly divide the range of area 3.

[0050] It is understandable that the area division device uses a mechanical structure to divide the area, which has better reliability and is suitable for high and low temperature environments. At the same time, it can adapt to different vehicle types and driving scenarios. Whether it is a small car, a large truck, a bus or a special vehicle, it can be adjusted according to the size, height, width and driving characteristics of the vehicle to achieve the best area division effect.

[0051] In some possible implementations of the present invention, see Figure 1 As shown, the area dividing device further includes: a supporting member 4, a first end of the supporting member 4 is connected to the second rotation adjustment mechanism 3, and a second end of the supporting member 4 is connected to the three-dimensional H-point device.

[0052] In this embodiment, a stable connection point is provided for the entire area division device by providing the support member 4. Furthermore, the support member 4 is connected to the three-dimensional H-point device, and the stability of the three-dimensional H-point device can be used to ensure that the optical indicator 1, the first rotation adjustment mechanism 2, and the second rotation adjustment mechanism 3 will not be displaced unnecessarily during operation due to the vibration of the vehicle or other external force interference, so that the optical indicator 1 can always be kept at the accurate position of the driver's eye point, thereby improving the accuracy of area division.

[0053] The three-dimensional H-point device is a standard tool for determining the position and posture of the driver in the vehicle. In this embodiment, the support member 4 is connected to the three-dimensional H-point device to ensure that the optical indicator 1 and the driver's eye position always maintain a relatively fixed relationship. Therefore, when adjusting the optical indicator 1, the driver's line of sight can be simulated more accurately, so that the area division is more in line with the actual driving situation.

[0054] The support member 4 may be a metal rod, a carbon fiber tube, etc., which is not limited in the present invention. The first end of the support member 4 may be firmly connected to the second rotation adjustment mechanism 3 by means of bolts, welding or clamps, and the second end may be connected to the three-dimensional H-point device by a fixing device. In practical applications, a mounting seat may be provided on the three-dimensional H-point device, and the second end of the support member 4 may be inserted into the mounting seat and fixed by tightening bolts.

[0055] In some possible implementations of the present invention, see Figure 2 As shown, the first rotation adjustment mechanism 2 includes: a rotating component 21 and a base plate 22; the rotating component 21 is rotatably disposed on the base plate 22, and the optical indicator 1 is relatively fixed to the rotating component 21.

[0056] In this embodiment, the rotating member 21 can rotate on the base plate 22, providing a basis for adjusting the angle of the optical indicator 1 in the vertical plane. This rotation can be continuous or step-by-step, and can meet the needs of regional division with different precision requirements. For example, in the division of area 1, it is necessary to accurately adjust the angle of the laser beam to cover a specific roof area and a specific range on both sides of the vehicle. The flexible rotation of the rotating member 21 can enable the optical indicator 1 to quickly and accurately align with the target area. In addition, the base plate 22 provides a stable support platform for the rotating member 21. During the driving of the vehicle, it will be subject to various vibrations and bumps, and the base plate 22 can ensure that the rotating member 21 remains relatively stable during operation, and will not shake or displace significantly due to external interference. This enables the optical indicator 1 to always maintain an accurate angular position, improving the accuracy and reliability of regional division.

[0057] The base plate 22 may be a flat plate base plate 22 or a grooved base plate 22. For example, the base plate 22 is a flat plate base plate 22, including a horizontal plate and two vertical plates arranged opposite to each other, the two vertical plates are perpendicular to the horizontal plate, a rotating shaft is arranged between the two vertical plates, a rotating member 21 is sleeved on the rotating shaft, and the optical indicator 1 is relatively fixed to the rotating member 21; the base plate 22 is a grooved base plate 22, a groove begins to be formed on the upper surface of the grooved base plate 22, a rotating shaft is arranged in the groove, and the rotating member 21 is installed in the groove and connected to the rotating shaft.

[0058] The rotating member 21 may be a rectangular rotating member 21, a spherical rotating member 21 or a disc-shaped rotating member 21, etc. In practical applications, an axial hole is provided at the center of the rotating member 21 for connecting with the rotating shaft on the base plate 22 to realize the rotatable function.

[0059] In some possible implementations of the present invention, see Figure 1 As shown, the first rotation adjustment mechanism 2 also includes: an angle indicating member 23, which is relatively fixed to the rotating member 21, and a first scale is arranged on the angle indicating member 23 along the rotation direction of the optical indicator 1, and the first scale is arranged relative to the base plate 22, and a first indication mark is arranged on the base plate 22 at a position relative to the first scale.

[0060] In this embodiment, the first scale on the angle indicating member 23 is relatively fixed to the rotating member 21. When the rotating member 21 drives the optical indicator 1 to rotate, the angle indicating member 23 also rotates synchronously. In this way, by reading the first scale on the angle indicating member 23, the rotation angle of the optical indicator 1 in the vertical plane can be accurately determined. For example, when dividing a specific area, the optical indicator 1 needs to be accurately adjusted to a specific angle. The angle indicating member 23 can provide accurate angle readings to ensure the accuracy of the adjustment.

[0061] Among them, the angle indicating component 23 is relatively fixed to the rotating component 21, which can be achieved by welding, bolt connection or integrated design, etc., as long as the angle indicating component 23 can accurately reflect the rotation angle of the rotating component 21, the present invention does not limit this.

[0062] The angle indicating member 23 is evenly distributed with first scales along the rotation direction of the optical indicator 1, so as to accurately measure the rotation angle of the rotating member 21. The unit of the first scale can be selected according to actual needs, such as degrees, radians, etc. At the same time, the accuracy of the first scale can also be adjusted according to specific application requirements to meet different angle measurement accuracy requirements.

[0063] The first scale is arranged relative to the base plate 22, so that when the rotating member 21 and the angle indicating member 23 rotate, the first scale moves relative to the base plate 22. By observing the relative position change between the first scale and the base plate 22, the rotation angle of the rotating member 21 can be determined. For example, when the rotating member 21 drives the optical indicator 1 to rotate to a certain angle, a certain value on the first scale will be aligned with the first indication mark on the base plate 22, so that the current rotation angle value can be read.

[0064] The first indicator mark may be an obvious mark, such as an arrow, a scale line or a number, so as to more intuitively read the rotation angle of the rotating member 21. When the rotating member 21 rotates, the first indicator mark will align with different values ​​on the first scale, so that the current rotation angle can be quickly and accurately determined.

[0065] In addition, in order to read the rotation angle of the optical indicator 1 in the vertical plane, there may also be the following configuration: the first rotation adjustment mechanism 2 further includes: an angle measuring component, which is relatively fixed to the rotating component 21 .

[0066] In this embodiment, the angle measuring component can provide a more accurate angle measurement result, ensuring that the rotation angle of the optical indicator 1 in the vertical plane is accurately acquired.

[0067] The angle measuring component may be an inclinometer, etc. In practical applications, when the rotating component 21 drives the optical indicator 1 to rotate in a vertical plane, the angle measuring component will also rotate together, so that the angle measuring component can directly measure the actual rotation angle of the rotating component 21 and accurately reflect the angle change of the optical indicator 1.

[0068] In some possible implementations of the present invention, see Figure 2 As shown, the second rotation adjustment mechanism 3 includes: a horizontal turntable 31, and the base plate 22 is rotatably disposed on the horizontal turntable 31.

[0069] In this embodiment, the horizontal turntable 31 can rotate freely in the horizontal plane, providing a basis for adjusting the angle in the horizontal plane for the base plate 22 and the optical indicator 1 and the first rotation adjustment mechanism 2 connected thereto. This rotation can be continuous or step-by-step, and can meet the needs of regional division with different precision requirements. For example, when determining the overall direction of regional division, the emission angle of the optical indicator 1 can be adjusted by rotating the horizontal turntable 31 so that it can accurately cover the area to be divided.

[0070] The horizontal turntable 31 has a circular or approximately circular shape so as to monitor the rotation angle of the base plate 22 in the horizontal plane.

[0071] Specifically, a rotating shaft is disposed on the upper surface of the horizontal turntable 31, the rotating shaft is perpendicular to the horizontal turntable 31, and the base plate 22 is connected to the rotating shaft to realize the rotatable function of the base plate 22. In practical applications, the rotating shaft can be driven by a motor disposed on the lower surface of the horizontal turntable 31, so that the base plate 22 can rotate in a horizontal plane, thereby driving the optical indicator 1 to rotate in the horizontal plane.

[0072] In some possible implementations of the present invention, see Figure 1 As shown, a second scale is provided on the horizontal turntable 31 along the rotation direction of the base plate 22 , the second scale is arranged opposite to the base plate 22 , and a second indication mark is arranged on the base plate 22 at a position relative to the second scale.

[0073] In this embodiment, the second scale on the horizontal turntable 31 is arranged relative to the base plate 22, so that when adjusting the rotation angle of the base plate 22 on the horizontal turntable 31, the rotation angle can be accurately determined by reading the value on the second scale.

[0074] The second scale is arranged opposite to the base plate 22, and is used to measure and indicate the rotation angle of the base plate 22 on the horizontal turntable 31. In practical applications, by reading the value on the scale, the rotation angle of the base plate 22 relative to the initial position can be accurately determined.

[0075] Specifically, the second scale is evenly arranged on the upper surface of the horizontal rotating disk 31 along the circumferential direction of the horizontal rotating disk 31, so as to accurately measure the rotation of different angles. The unit of the second scale can be selected according to actual needs, such as degree, radian, etc. At the same time, the second scale can use numbers, lines or other marking forms to represent different angle values.

[0076] The second indicator mark is used in conjunction with the second scale mark on the horizontal turntable 31 to more accurately read the rotation angle of the base plate 22. In actual application, when the base plate 22 rotates on the horizontal turntable 31, the indicator mark will point to different scale marks on the horizontal turntable 31, thereby displaying the current angle position of the base plate 22.

[0077] Specifically, the second indicator mark can be an arrow, a mark point or other obvious symbols, etc. In practical applications, the second indicator mark is located at a fixed position on the base plate 22, so that when the base plate 22 rotates, the indicator mark can always correspond to the second scale on the horizontal turntable 31.

[0078] In some possible implementations of the present invention, see Figure 1 and Figure 2As shown, a first positioning member 5 and a second positioning member 6 are provided on the base plate 22; the first positioning member 5 penetrates the base plate 22 along a first direction, and the first positioning member 5 is used to press the rotating member 21; the second positioning member 6 penetrates the base plate 22 along a second direction, and the second positioning member 6 is used to press the horizontal turntable 31.

[0079] In this embodiment, the first positioning member 5 penetrates the base plate 22 along the first direction and presses the rotating member 21, which can effectively prevent the rotating member 21 from loosening or displacement during operation. When the optical indicator 1 rotates in the vertical plane with the rotating member 21, the stable connection can ensure the accuracy and reliability of the angle adjustment. The second positioning member 6 penetrates the base plate 22 along the second direction and presses the horizontal turntable 31, which can effectively prevent the base plate 22 from loosening or displacement during operation. When the optical indicator 1 rotates in the horizontal plane with the base plate 22, the stable connection can ensure the accuracy and reliability of the angle adjustment.

[0080] The first positioning member 5 and the second positioning member 6 can both be top screws. In practical applications, when it is necessary to fix the position of the rotating member 21 so that it cannot rotate at will, the first positioning member 5 can be adjusted to tightly press the rotating member 21, thereby achieving the positioning of the rotating member 21. In addition, when the second positioning member 6 penetrates the base plate 22 along the second direction and presses the horizontal turntable 31, the relative movement between the base plate 22 and the horizontal turntable 31 can be effectively limited by friction and other effects, thereby preventing the base plate 22 from rotating on the horizontal turntable 31.

[0081] Specifically, the first direction may be a direction perpendicular to the surface of the base plate 22 , and the second direction may be a direction perpendicular to the surface of the horizontal turntable 31 .

[0082] In some possible embodiments disclosed in the present invention, the optical indicator 1 is a cross laser pen; the driver's eye point is located directly above the riding reference point, and the distance between the riding reference point and the driver's eye point is 635 mm.

[0083] In this embodiment, the cross laser pen can emit a clear cross-shaped laser pattern, which can clearly indicate a specific direction and position in space. Furthermore, in the area division, the cross laser can more accurately define the boundaries of different areas, so that the driver and relevant personnel can intuitively see the area range that needs attention. At the same time, it should be noted that setting the driver's eye point just above the riding reference point and determining the interval between the two to be 635mm can make the area division more in line with the driver's actual perspective and observation needs, and improve the practicality and effectiveness of the area division.

[0084] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0085] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
