Description
Technical Field
[0001] This invention relates to an intelligent car and motorcycle adaptive steering rearview mirror, belonging to the field of car and motorcycle manufacturing. Background Technology
[0002] Existing rearview mirrors for cars and motorcycles lack automatic adjustment. While they don't obstruct the driver's view during straight driving and small turns, they become obstructed during larger turns, especially when towing semi-trailers or full trailers. The driver's side mirror's view is blocked by the trailer when turning left, and the passenger side mirror's view is further away from the vehicle due to the turning of the tractor or trailer, making it impossible to observe pedestrians, vehicles, and obstacles within the turning radius. The opposite occurs when turning right. Especially during larger and maximum turns, the rearview mirror completely obscures the road conditions outside the vehicle's side, forcing drivers to rely on intuition, experience, and anticipation of road conditions. If an emergency occurs at this time, the inability to effectively observe and take timely evasive action poses a significant safety hazard to pedestrians, non-motorized vehicles, and other motor vehicles. Similarly, when a motorcycle makes a sharp left turn, the view in the left rearview mirror is obstructed by the rider's body, and the view in the right rearview mirror is further behind the motorcycle due to the handlebars turning. The opposite is true when turning right. Obviously, turning a motorcycle requires a high level of concentration, and glancing at the rearview mirror out of the corner of one's eye is much more convenient and safer than turning one's head to look at the sides and rear. This is one of the reasons why accidents are more frequent when vehicles are turning or making U-turns. Summary of the Invention
[0003] In order to solve the above-mentioned problems in the prior art, the purpose of this invention is to provide a safer, more efficient, convenient, stable, reliable and cost-effective intelligent car and motorcycle following steering rearview system.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an intelligent car and motorcycle adaptive steering rearview mirror, including a sensor mounting bracket mounted on the frame with the steering gear on the same plate, a steering analog signal sensor on the upper part, the linkage contact shift fork of the sensor being connected to the steering gear rocker arm, the wiring terminals of the sensor being connected to the corresponding wiring terminals of the analog signal function processing control unit through a line, and the other end of the control unit being connected to the wiring terminals of the rearview mirror manual adjustment control switch and the horizontal adjustment servo motors of the left and right rearview mirrors through a line respectively.
[0005] Furthermore, the sensor's contact fork and the steering rocker arm move in parallel and synchronously through a flexible hinge formed by two ball joints and an adjustable push rod, and the automatic adjustment range for the left and right sides is set to the range of 10 degrees to 40 degrees respectively.
[0006] Furthermore, the analog signal function processing control unit receives the position signal from the steering analog signal sensor, performs analog analysis and amplification processing, and immediately issues a power command to cause the horizontal adjustment servo motors on the left and right rearview mirror adjustment supports to rotate synchronously in the same direction as the steering angle.
[0007] Furthermore, in addition to switching between the automatic and manual adjustment functions, the rearview mirror manual adjustment control switch also has the function of connecting and disconnecting the linkage relationship between the horizontal adjustment servo motors of both rearview mirrors, so that the lens angles of both rearview mirrors can be adjusted horizontally left and right independently, and the vertical adjustment servo motors of both sides can be controlled to adjust vertically up and down.
[0008] The beneficial effects of this invention are as follows: This follow-up steering rearview system adopts a synchronous linkage design between the sensor contact fork and the steering gear rocker arm. On motorcycles, it is mounted on the front fork axle of the handlebars and steering wheel. It can reflect the steering position information in real time, accurately and reliably. Therefore, this follow-up steering rearview system works stably and reliably, allowing the rearview angles of the left and right rearview mirrors to rotate synchronously and in the same direction with the steering angle. This completely improves the blind spots when turning on tractor-trailers, full trailers, motorcycles, etc., greatly reduces the risk of accidents, and effectively protects personal and property safety. Compared with the prior art, the cost is slightly increased, but the convenience and safety are greatly improved, which is of great significance. Therefore, it has a high cost performance and wide applicability. Attached Figure Description Figure 1 The image shows an intelligent car and motorcycle adaptive steering rearview system.

Specific implementation methods
[0011] like Figure 1The intelligent car / motorcycle adaptive steering rearview system shown includes: a left rearview mirror 1 and a right rearview mirror 3, fixed to the cab or motorcycle handlebars by a rearview mirror mounting bracket 2; a worm gear spline 9 mounted on the upper part of the steering gear 10, connecting a telescopic fork, a universal joint, and a steering wheel; a lower steering gear rocker arm 16 connected to a movable rod contact fork 13 of a steering analog signal sensor 12 via a ball joint 15 and an adjustable push rod 14; and a steering analog signal sensor 12 mounted on the frame along with the steering gear 10 via a sensor mounting bracket 11. When applied to a motorcycle, this steering analog signal sensor... The analog signal sensor 12 is installed at the triangular platform of the front fork shaft. Its contact fork 13 is connected to the front fork fixing bracket through the ball joints 15 on both sides and the adjustable push rod 14. The wiring terminals of the sensor 12 are connected to the analog signal function processing control unit 8 through primary and secondary lines. One end of the rearview mirror manual adjustment control switch 7 opens and closes the power supply terminal of the control unit 8. The other wiring terminals are connected to the power supply, ground, and the horizontal adjustment servo motors 5 and vertical adjustment servo motors 6 of the two rearview mirrors, respectively. The output terminal of the analog signal function processing control unit 8 is connected to the horizontal adjustment servo motor 5.
[0012] Furthermore, the contact fork 13 of the steering analog signal sensor 12 and the steering rocker arm 16 form parallel synchronous motion through the flexible hinge of the ball joints 15 at both ends and the adjustable push rod 14, and the left and right automatic adjustment ranges are respectively set to the range of 10 degrees to 40 degrees.
[0013] Furthermore, the analog signal function processing control unit 8 receives the position signal from the steering analog signal sensor 12, performs analog analysis and amplification processing, and immediately issues a power command to cause the horizontal adjustment servo motors 5 on the left and right rearview mirror adjustment supports 4 to rotate horizontally in the same direction as the steering angle.
[0014] Furthermore, the rearview mirror manual adjustment control switch 7, in addition to switching between the above-mentioned automatic and manual adjustment functions, also has the function of connecting and disconnecting the parallel connection of the horizontal adjustment servo motors 5 of the two rearview mirrors, so that the lens angles of the two rearview mirrors 1 and 3 can be adjusted horizontally left and right independently, and the vertical adjustment servo motor 6 can be controlled to adjust vertically up and down.
[0015] Existing rearview mirrors lack adaptive steering adjustment. The preset rearview angle is only suitable for normal straight driving and small turns. When reversing, making a U-turn, or crossing traffic lights, the mirrors cannot effectively observe vehicles, pedestrians, and obstacles within the turning radius. When turning right, the blind spot on the passenger side makes driving more dangerous. Relying solely on driving experience and advance prediction of road conditions is insufficient to cope with the increasingly frequent traffic behaviors of pedestrians, non-motorized vehicles, and other vehicles, such as passing, overtaking, changing lanes, and even failing to yield. Motorcycles also pose similar safety hazards, which has long been one of the sources of frequent accidents.
[0016] This intelligent adaptive steering rearview system features an automatic tracking and adjustment design for the angles of the side mirrors. When a car or motorcycle turns left, the control unit, based on the input signal from the steering simulation position sensor, synchronously issues a command to control the angles of the side mirrors to rotate to the left simultaneously with the vehicle's turning angle, based on their current position. When turning right, the angles of the side mirrors rotate to the right simultaneously. When the steering wheel is straightened, the angles of the side mirrors return to their original positions synchronously with the steering angle. In other words, when the vehicle turns, the rearview mirror angles follow the same direction; when the turn stops, the rearview mirror adjustment stops; and when the steering wheel is straightened, the rearview mirror angles return to their original positions. The adjustment range of this adaptive steering rearview system is set from 10 degrees to 40 degrees, slightly larger than the maximum turning angle of the outer wheel (33.5 degrees). When the front wheel steering angle is below 10 degrees, due to the small deflection angle and clear rear visibility, the adaptive steering adjustment system does not intervene, avoiding unnecessary adjustments that interfere with normal driving. This completely eliminates safety hazards caused by blind spots, significantly improving driving convenience and safety.
[0017] By controlling the input power of the analog signal processing control unit, the rearview mirror manual adjustment control switch adds automatic and manual mode switching functions, while retaining the original vehicle function of manually adjusting the horizontal and vertical angles of both rearview mirrors independently. It also has the function of setting the original position of the rearview mirrors before automatic adjustment. Without replacing the original vehicle wiring, without conflict, and with a small economic investment, it achieves intelligent fully automatic control, ensures driving safety, and solves a long-criticized industry problem. Therefore, it is cost-effective and easy to promote.
