Description

Technical Field

[0001] The invention relates to the technical field of steering wheels, and in particular to a steering wheel with an anti-fatigue warning function. Background Art

[0002] The steering wheel is a wheel-shaped device for controlling the driving direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. The steering drive shaft serves as a connecting part between the steering gear and the steering shaft, which is conducive to the universalization of the steering gear, compensates for the errors generated during manufacturing and installation, and makes the installation of the steering gear and steering wheel on the vehicle more reasonable.

[0003] Chinese patent authorization announcement No. CN115027376A discloses an intelligent steering wheel for fatigue driving detection, including a steering wheel and a detector. The detector includes an instrument body, a mounting hoop and an electronic control tube. A camera is arranged on the front of the instrument body. The electronic control tube is in an arc-shaped structure and is closed at both ends. A connecting column is fixedly connected to the inner surface of the arc of the electronic control tube. Firstly, it is convenient to install, applicable to more vehicles, and convenient to promote. Secondly, it is closest to the driver to facilitate the collection of clearer image information and ensure that the driving field of view is not blocked, thereby achieving the effect of convenient installation.

[0004] The above-mentioned existing technical solution has the following shortcomings: the steering wheel uses the sliding of a steel ball inside the arc-shaped electric control tube to realize the opening and closing control of the camera, thereby detecting the driver's fatigue level. However, in this structure, when the driver is tired, his hand control of the steering wheel is uncertain. When the driver is partially fatigued driving, the steering wheel will spin due to fatigue control, and then it cannot be guaranteed that the steel ball can slide smoothly to the lowest point, which in turn causes the camera to fail to start, and it is difficult to effectively remind the driver. In addition, the device only uses voice broadcast to warn, and its warning method is single. Summary of the invention

[0021] In order to solve the problem that the fatigue warning response effect of the existing steering wheel is general and the warning method is single, the following solution is disclosed, specifically: Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown: A steering wheel with an anti-fatigue warning function, comprising a connecting part 1, a rim 2 is arranged on the outside of the connecting part 1, and warning components 15 are evenly arranged on both sides of the inside of the rim 2, through holes 19 are evenly opened on the two outer edges of the rim 2, and the outer sides of multiple warning components 15 penetrate into the corresponding through holes 19, electromagnetic slide rails 11 are installed on both inner side walls of the rim 2, and electromagnetic sliders 12 are slidably installed inside the electromagnetic slide rails 11, and the outer sides of the electromagnetic sliders 12 are connected to top blocks 13, and abutment blocks 14 are installed on the side of multiple warning components 15 close to the electromagnetic slide rails 11, and the connecting part 1 is provided with an early warning start mechanism, which uses the judgment and detection of the driver's hand gripping force to determine whether to start the early warning component 15, and the early warning start mechanism includes a control main board 18 arranged on the connecting part 1, and a plurality of pressure sensors 17 arranged on the two outer edges of the bottom end of the rim 2, the pressure sensors 17 are used to detect the driver's gripping force on the rim 2, and the control main board 18 is used to control whether to start the electromagnetic slide rail 11 and the electromagnetic slider 12; the two groups of pressure sensors 17 are connected to the control main board 18 by signal, and a timer is provided inside the control main board 18, and the control main board 18 is connected to the timing The control mainboard 18 is connected with the electromagnetic slide rail 11 and the electromagnetic slider 12 by signal. When the gripping force disappears, the control mainboard 18 is used to start the timer to determine the duration of the loss of force. After the expected duration is reached, the control mainboard 18 starts the electromagnetic slide rail 11 and the electromagnetic slider 12. The cross section of the electromagnetic slide rail 11 is arc-shaped, the cross section of the top block 13 is semicircular, and the cross section of the abutment block 14 is arc-shaped. When the top block 13 slides along the electromagnetic slide rail 11, the curved surface of the top block 13 and the curved surfaces of the plurality of abutment blocks 14 contact and abut against each other in sequence and then separate. The early warning component 15 includes a U-shaped block 1501 movably installed inside the wheel rim 2, and Springs 1502 are installed on both sides of the bottom of the U-shaped block 1501, and the two groups of springs 1502 are respectively located on both sides of the electromagnetic slide rail 11.

[0022] In this embodiment, during use, due to the driver's gripping posture on the wheel rim 2, the left and right groups of pressure sensors 17 receive pressure signals to ensure a normal driving state. When driving fatigued, the grip force of the driver's fingers on the wheel rim 2 disappears, so that the force on the left and right groups of pressure sensors 17 disappears, and the information is transmitted to the control main board 18 through an electrical signal to start the timer, count the force elimination time, and reduce the possibility of false triggering. Then, after the grip force disappears for a long time, the electromagnetic slide rail 11 and the electromagnetic slider 12 are controlled to start, so that the electromagnetic slider 12 slides along the electromagnetic slide rail 11, and the top block 13 moves synchronously under the sliding of the electromagnetic slider 12, and squeezes the resisting block 14 in turn. Due to the special structure of the resisting block 14, the resisting block 14 is pushed outward, so that the top column 1503 extends to the outside of the through hole 19, and the spring 2 1502 is stretched. The top column 1503 is used to push out the outer side of the wheel rim 2 to stimulate the palm of the driver with a virtual grip, thereby achieving the effect of fatigue warning. Example

[0023] This embodiment is different from the first embodiment. By using the pressurized water spraying mechanism 10, the driver's face is sprayed with water to stimulate and remind the driver of fatigue driving.

The water mechanism 10 is provided with a pressurized water spray mechanism 10, and one end of the pressurized water spray mechanism 10 extends to the interior of the lower cavity 9; the interior of the upper cavity 8 is filled with water, and the interior of the lower cavity 9 is filled with air, and the nozzle 4 and the water supply pipe 5 are both one-way pipes; the pressurized water spray mechanism 10 includes an air cylinder 1001 installed inside the wheel rim 2, and the end of the air cylinder 1001 away from the electromagnetic slide rail 11 is penetrated by a piston rod 1002, and the outer sleeve of the piston rod 1002 is provided with a spring 1003, and one end of the spring 1003 is connected to one end of the air cylinder 1001 Two guide holes 1005 are provided on opposite sides of the electromagnetic slide rail 11 near the gas cylinder 1001, and a connecting wire rope 1004 is passed through the inside of the guide hole 1005. The two ends of the connecting wire rope 1004 extend along the inner cavity of the wheel rim 2 and are connected to the two sides of the outer end of the piston rod 1002. A connecting pipe 1006 is passed through the side of the gas cylinder 1001 away from the piston rod 1002, and one end of the connecting pipe 1006 is passed through the inside of the lower cavity 9. The outside of the guide hole 1005 is sleeved with a wire ring 16, and the wire The bottom ends of the rings 16 are connected to the inner wall of the wheel rim 2, and the guide holes 1005 are guided by the wire rings 16; the distance from the guide holes 1005 to one end of the electromagnetic slide rail 11 close to the pressurized water spraying mechanism 10 is equal to the compression distance of the piston rod 1002 in the air cylinder 1001, and the electromagnetic slider 12 is slid inside the electromagnetic slide rail 11, and then the electromagnetic slider 12 contacts and squeezes the guide hole 1005, so that one end of the guide hole 1005 is stretched, and the other end pulls the piston rod 1002 to compress toward the air cylinder 1001.

[0024] In this embodiment, since the electromagnetic slider 12 slides from top to bottom, when the electromagnetic slider 12 slides to near the lower end of the electromagnetic slide rail 11, the electromagnetic slider 12 contacts the guide hole 1005 that crosses the electromagnetic slide rail 11. Due to the continuous sliding of the electromagnetic slider 12, one end of the guide hole 1005 is pulled, so that the other end of the guide hole 1005 pulls the piston rod 1002 to move outward, so that the piston rod 1002 squeezes the inside of the air cylinder 1001, thereby compressing the air inside the air cylinder 1001 and transmitting it to the inside of the lower cavity 9 through the connecting pipe 1006, so that the control proportion in the water tank 6 is increased, thereby pushing the movable partition 7 to squeeze the water flow inside the upper cavity 8 upward, so that the nozzle 4 sprays water outward, and utilizes the spray stimulation of the water flow on the driver's face to further promote the fatigue warning effect on the driver, and utilizes the function of the observation window 3 to penetrate the amount of water pre-stored in the water tank 6 at any time, and cooperates with the water adding pipe 5 to increase the water amount in the water tank 6.
