Description

Technical Field

[0001] The utility model relates to the technical field of integrated steering wheels, in particular to an integrated intelligent steering wheel for driver monitoring. Background Art

[0002] With the rapid development of the automotive industry and the continuous progress of automotive intelligent technologies, driving safety has become the focus of common concern inside and outside the industry. The traditional steering wheel design mainly focuses on handling performance and driving comfort, but it seems inadequate in dealing with the increasingly complex safety challenges in the modern driving environment. Especially when autonomous driving technology has not been fully popularized, the concentration of the driver's attention and the immediate control ability of the vehicle are still the key factors to ensure driving safety.

[0003] Although the current steering wheel designs on the market have made remarkable progress in terms of handling performance and comfort, there are still obvious deficiencies in driver monitoring and warning functions. Specifically, it is difficult for traditional steering wheels to give timely warnings when the driver does not hold the steering wheel. In the case of long-distance driving or when the driver's attention is distracted, if the steering wheel fails to timely detect the driver's hand-holding state and provide an effective warning when the hand leaves the steering wheel, the risk of accidents will be greatly increased.

[0004] Although there are steering wheels on the market that can perform warning functions currently, their driver monitoring systems highly rely on electronic sensors, cameras and other electronic devices. These devices may malfunction or fail in extreme environments (such as high temperature, high humidity, electromagnetic interference, etc.), resulting in the system being unable to work properly. Moreover, due to the use of a large number of electronic components and complex algorithm processing, the cost of the driver monitoring system is relatively high, making it difficult to be popularized and applied in ordinary vehicle models.

[0005] Furthermore, we disclose an integrated intelligent steering wheel for driver monitoring to meet the actual needs in the prior art that it is difficult to give warnings in extreme environmental states when the driver's hand leaves the steering wheel and to make the overall cost moderate. Summary of the Utility Model

[0006] In view of this, the purpose of the present utility model is to provide an integrated intelligent steering wheel for driver monitoring to solve the problems in the prior art that it is difficult to give warnings in extreme environmental states when the driver's hand leaves the steering wheel and to make the overall cost moderate.

[0007] For the above purposes, the present utility model provides an integrated driver monitoring intelligent steering wheel, which includes a mounting seat with multiple technical modules arranged inside. The outer wall of the mounting seat is fixedly connected with a plurality of connecting plates at equal intervals. One end of each of the plurality of connecting plates away from the mounting seat is fixedly connected with a connecting sleeve. An upper spoke is fixedly connected between the upper ends of the plurality of connecting sleeves, and a lower spoke is slidably connected between the lower ends of the plurality of connecting sleeves. The lower spoke is slidably connected with the upper spoke. An opening groove is formed on one side of the upper end of one of the connecting plates close to the mounting seat. A warning lamp for warning the driver is arranged inside the opening groove. A control component is arranged inside the upper spoke and the lower spoke, and the control component is used to control the warning lamp to rotate and give an alarm.

[0008] Preferably, both the lower spoke and the upper spoke are arc-shaped. A limiting ring is fixedly connected to the upper end surface of the lower spoke, and a sliding plate is fixedly connected to the lower end surface of the upper spoke. The sliding plate is slidably connected inside the limiting ring. A plurality of reset springs are fixedly connected to the inner bottom surface of the limiting ring at equal intervals. The upper ends of the reset springs are fixedly connected with the sliding plate.

[0009] Preferably, the control component includes a plurality of lifting arc plates. The number of the lifting arc plates is the same as that of the lower spoke and the upper spoke, and the lifting arc plates are arranged between the upper spoke and the lower spoke.

[0010] Preferably, the lifting arc plate is arc-shaped. A plurality of support plates are fixedly connected to the lower end of the lifting arc plate at equal intervals. The lower ends of the support plates are fixedly connected with the inner wall of the lower spoke.

[0011] Preferably, a steel wire rope is slidably connected inside the plurality of lifting arc plates. Both ends of the steel wire rope are wound around and connected with the connecting plate provided with the opening groove. One end of the steel wire rope is fixedly connected with the connecting plate provided with the opening groove, and the other end of the steel wire rope is slidably connected with the connecting plate and extends into the opening groove.

[0012] Preferably, a mounting block is arranged in the middle of the opening groove. A rotating shaft is fixedly connected to one side of the mounting block close to the mounting seat. Both ends of the rotating shaft are rotatably connected with the connecting plate, and a torsion spring is arranged at the connection. One end of the steel wire rope extending into the opening groove is fixedly connected with the upper end surface of the mounting block on the side away from the mounting seat.

[0013] Preferably, the middle of the mounting block is fixedly connected with the warning lamp. A conductive column is fixedly connected to the middle of the end face of the mounting block away from the warning lamp. The conductive column is electrically connected with the warning lamp. Conductive elastic pieces are fixedly connected to both sides of the middle of the lower end inside the opening groove.

[0014] Advantages of the present utility model: The integrated driver monitoring intelligent steering wheel can monitor the hand-holding state of the driver in real time. Once it detects that the driver is not holding the steering wheel, it immediately triggers the warning light to rotate perpendicular to the steering wheel and gives a timely and eye-catching warning to the driver in the form of sound and light alarm, effectively preventing the accident risks caused by distracted attention or fatigue driving. In addition, the design of this steering wheel also takes into account cost-effectiveness and durability. It adopts a warning mechanism that is not highly dependent on electronic components, and can maintain stable operation even in extreme environments. Using a pure mechanical structure greatly reduces the system failure rate. At the same time, the sliding connection design between the upper spoke and the lower spoke not only enhances the structural strength of the steering wheel, but also uses the distance between the two to trigger the control component, improving the monitoring accuracy of the driver's hand-holding state.

Detailed Embodiment

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further describe the present utility model in detail with reference to specific embodiments.

[0024] As shown Figures 1 to 5 in the figure, an integrated driver monitoring intelligent steering wheel includes a mounting seat 3 with multiple technical modules arranged inside. The outer wall of the mounting seat 3 is fixedly connected with a plurality of connecting plates 2 at equal intervals. One end of each of the plurality of connecting plates 2 far from the mounting seat 3 is fixedly connected with a connecting sleeve 1. An upper spoke 4 is fixedly connected between the upper ends of the plurality of connecting sleeves 1. A lower spoke 11 is slidably connected between the lower ends of the plurality of connecting sleeves 1. The lower spoke 11 is slidably connected with the upper spoke 4. On one side near the mounting seat 3 at the upper end of one of the connecting plates 2, an opening groove 7 is provided. Inside the opening groove 7, a warning lamp 14 for warning the driver is arranged. A control component is arranged inside the upper spoke 4 and the lower spoke 11. The control component is used to control the warning lamp 14 to rotate and give an alarm;

[0025] This integrated detection intelligent steering wheel can monitor the hand-holding state of the driver in real time. Once it detects that the driver does not hold the steering wheel, it immediately triggers the warning lamp 14 to rotate and makes it perpendicular to the steering wheel, and gives a timely and eye-catching warning to the driver in the form of sound and light, effectively preventing the accident risk caused by distraction or fatigue driving. In addition, the design of this steering wheel also takes into account cost-effectiveness and durability. It adopts a warning mechanism that is not highly dependent on electronic components, and can maintain stable operation even in extreme environments. Using a pure mechanical structure method greatly reduces the system failure rate. At the same time, the sliding connection design of the upper spoke 4 and the lower spoke 11 not only enhances the structural strength of the steering wheel, but also uses the distance between the two to trigger the control component, improving the monitoring accuracy of the driver's hand-holding state.

[0026] As shown Figure 3 in the figure, both the lower spoke 11 and the upper spoke 4 are arc-shaped. A limiting ring 10 is fixedly connected to the upper end surface of the lower spoke 11. A sliding plate 8 is fixedly connected to the lower end surface of the upper spoke 4. The sliding plate 8 is slidably connected inside the limiting ring 10. A plurality of reset springs 9 are fixedly connected to the inner bottom surface of the limiting ring 10 at equal intervals. The upper ends of the reset springs 9 are fixedly connected to the sliding plate 8;

[0027] When the driver normally holds the steering wheel, the distance between the upper spoke 4 and the lower spoke 11 changes. At this time, the reset springs 9 are in a compressed state and do not trigger the warning mechanism. However, once the driver's hand leaves the steering wheel, the relative distance between the upper spoke 4 and the lower spoke 11 changes. The lower spoke 11 moves through the reset springs 9. The lower spoke 11 drives the support plate 12 to move, causing the plurality of lifting arc plates 5 to be misaligned, thereby driving the control component to make the warning lamp 14 rotate.

[0028] As shown Figures 2 to 5As shown in the figure, the control component includes a plurality of lifting arc plates 5. The number of lifting arc plates 5 is the same as that of the lower disc spokes 11 and the upper disc spokes 4. The lifting arc plates 5 are arranged between the upper disc spokes 4 and the lower disc spokes 11. The lifting arc plates 5 are arc-shaped. The lower ends of the lifting arc plates 5 are fixedly connected with a plurality of support plates 12 at equal intervals. The lower ends of the support plates 12 are fixedly connected with the inner wall of the lower disc spokes 11. A steel wire rope 6 is slidably connected inside the plurality of lifting arc plates 5. The two ends of the steel wire rope 6 are wound around and connected to the connecting plate 2 provided with an opening groove 7. One end of the steel wire rope 6 is fixedly connected to the connecting plate 2 provided with an opening groove 7. The other end of the steel wire rope 6 is slidably connected to the connecting plate 2 and extends into the inside of the opening groove 7. An installation block 17 is arranged in the middle of the opening groove 7. A rotating shaft 15 is fixedly connected to one side of the installation block 17 close to the installation seat 3. Both ends of the rotating shaft 15 are rotatably connected to the connecting plate 2, and a torsion spring 16 is arranged at the connection. The torsion spring 16 is arranged on the inner wall of the connecting plate 2 and sleeved outside the rotating shaft 15. One end of the steel wire rope 6 extending into the inside of the opening groove 7 is fixedly connected to one side of the upper end surface of the installation block 17 away from the installation seat 3. A warning lamp 14 is fixedly connected to the middle of the installation block 17. A conductive column 13 is fixedly connected to the middle of one side end face of the installation block 17 away from the warning lamp 14. The conductive column 13 is electrically connected to the warning lamp 14. Conductive elastic pieces 18 are fixedly connected to both sides of the middle of the lower end inside the opening groove 7. The conductive elastic pieces 18 are electrically connected to the battery inside the vehicle. When the engine works and the vehicle is running, power will be supplied to the conductive elastic pieces 18;

[0029] When the driver normally holds the steering wheel, due to the action of the hand pressure, the skateboard 8 will move synchronously, and misalignment will occur between multiple skateboards 8. At this time, the return spring 9 is still in a relatively compressed stable state. A steel wire rope 6 is connected inside multiple skateboards 8. The steel wire rope 6 is wound inside the connecting plate 2 and is slidably connected to the connecting plate 2, and is connected to the mounting block 17 through the opening groove 7. Once the driver's hand leaves the steering wheel, the return spring 9 begins to release the potential energy it has accumulated, pushing the lower disc spoke 11 to move. This movement causes a significant change in the relative positions between the skateboards 8, making multiple skateboards 8 in a horizontal plane, thereby causing the steel wire rope 6 to slide between the connecting plate 2 and the mounting block 17. As the tension of the steel wire rope 6 decreases, the mounting block 17 is affected by the torsion spring 16 on the rotating shaft 15 and begins to rotate around its rotating shaft 15, causing the mounting block 17 to rotate to a position perpendicular to the steering wheel. During the rotation of the mounting block 17, the conductive column 13 on it comes into contact with the conductive elastic piece 18 inside the opening groove 7, thus establishing an electrical connection. This connection provides the required electrical energy for the warning light 14, enabling it to emit light and sound an alarm. With the establishment of the electrical connection, the warning light 14 starts to work, emitting strong light signals and sound signals to attract the driver's attention. When the driver re-grips the steering wheel, the skateboard 8 returns to its original position under the action of the return spring 9, the steel wire rope 6 readjusts its position, and the mounting block 17 rotates back to its initial state under the action of the torsion spring 16, disconnecting the electrical connection and the warning light 14 goes out. At this time, the system re-enters the monitoring state, waiting for the next trigger. The conductive elastic piece 18 on this steering wheel is only powered by the vehicle's battery when the engine is running and the vehicle is moving. Therefore, when the vehicle is not moving and the driver's hand is not in contact with the steering wheel, the warning light 14 will not enter the alarm state.

[0030] The present utility model aims to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
