Description

Curved corner light supplement safety device

The invention relates to a safety device for traffic, in particular to a safety device for supplementary light in a curve.

In order to promote traffic safety, in general, the locomotive will turn on the main lights to illuminate the road ahead. The illuminating direction of the locomotive main lamp is directly in front of the front of the locomotive. The illuminating range is the range where the locomotive main lamp is centered outward to a certain angle. The area outside the illuminating range is the blind spot where the light cannot be irradiated. Such an irradiation range can usually meet the irradiation requirement when the locomotive is traveling straight.

When the locomotive is cornering, the dead angle that the main lamp cannot illuminate will seriously affect the traffic safety. In other words, since the locomotive driver cannot see the road surface condition on the turning direction side, the probability of a locomotive driver having a traffic accident will greatly increase. However, setting side lights on both sides of the locomotive body to normally compensate for the blind spot of the main light is also a waste of energy and will interfere with the sight of other passers-by.

Therefore, in order to solve the above problem, the object of the present invention is to provide a safety device for supplementing the light source when the locomotive crosses a curve.

The technical method adopted by the present invention to solve the problems of the conventional technology is to provide a corner light supplement safety device, including: an inertial measurement unit, which is arranged on a locomotive car body, and is arranged to sense one side of the locomotive car body Tilted state; two fill light components are provided on the body of the locomotive, and the fill light directions of the two fill light components respectively correspond to the left and right sides of the traveling direction of the locomotive body; and a fill light control component , The signal is connected to the inertial measurement unit and two of the fill light components, the fill light control component controls the compensation of the corresponding direction side according to the current roll state of the locomotive body sensed by the inertial measurement unit The light lamp member performs fill light.

Furthermore, the present invention can control the fill light member to perform fill light in a gradual brightening manner, so as to avoid a situation in which driving of the locomotive occurs because the fill light member is suddenly bright and the vision cannot be adjusted in a short time.

The specific embodiments adopted by the present invention will be further described by the following embodiments and accompanying drawings.

Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 4. This description is not intended to limit the embodiments of the present invention, but is one of the examples of the present invention.

As shown in FIG. 1 and FIG. 2, the corner fill light safety device 100 of the present invention includes an inertial measurement unit 1, a fill light member 2 and a fill light control member 3, wherein the fill light member 2 is two , Namely the left fill light 21 and the right fill light 22.

The inertial measurement unit 1 (that is, IMU, Inertial Measurement Unit) is installed on a locomotive car body S, and is configured to sense the roll state of the locomotive car body S (as shown in FIG. 2 ). Since the locomotive body S will roll when cornering, and the direction of the roll corresponds to the turning direction, the inertial measurement unit 1 can sense the roll state of the locomotive body S to know that the locomotive body S is moving Overbending. Specifically, the inertial measurement unit 1 is a device for measuring the attitude angle (or angular rate) and acceleration of an object in three axes (that is, the X, Y, and Z axes of a rectangular coordinate system), wherein the inertial measurement The unit 1 has a gyroscope and an accelerometer to measure the state parameters of the object's attitude, angular velocity, and acceleration in three-dimensional space.

The left fill light 21 and the right fill light 22 are provided on the locomotive body S, and the light source directions of the left fill light 21 and the right fill light 22 correspond to the left and right sides of the traveling direction of the locomotive body S, respectively.

The signal of the fill light control member 3 is connected to the inertial measurement unit 1, the left fill light 21 and the right fill light 22. As shown in FIG. 2, the fill light control member 3 controls the fill light member 2 corresponding to the side of the roll direction according to the current roll state of the locomotive body S sensed by the inertial measurement unit 1 (in FIG. 2 Fill light for the left fill light 21). In this embodiment, the roll state is a state where the center line of the locomotive body S has an angle with the vertical line of the road surface.

In this embodiment, the fill light control member 3 is provided to control the fill light member 2 to perform fill light when it is determined that the roll state of the locomotive vehicle body S exceeds a predetermined tilt angle threshold θ. In the second figure, the roll state of the locomotive body S is left-leaning, and the angle between the center line of the locomotive body S and the vertical line of the road surface just exceeds the tilt angle threshold θ, so the fill light control member 3 controls the left fill light The lamp 21 performs fill light.

As shown in FIG. 3, the fill light control member 3 is installed when it is determined that the roll state of the locomotive body S is returned to within the range of the tilt angle threshold θ (the center line of the locomotive body S and the vertical line of the road surface Angle θ1 is smaller than the tilt angle threshold θ), the left fill light 21 is controlled to end fill light. However, the present invention is not limited to this. The inclination angle threshold θ is a value that can be set arbitrarily, and the inclination angle threshold θ may not be set. As long as the inertial measurement unit 1 senses the roll state of the locomotive body S, the fill light control member 3 The fill light member 2 on the corresponding direction side is controlled to perform fill light.

Further, in this embodiment, the left fill light 21 and the right fill light 22 are normally turned off, and are turned on under the control of the fill light control member 3 to perform fill light.

In the present embodiment, the fill light control member 3 is provided to control the fill light member 2 corresponding to the roll direction side to perform fill light while controlling the fill light unit 2 corresponding to the roll direction according to the current roll state of the locomotive body S, and the control is opposite to the roll direction The fill light member 2 on the side stops the fill light. As shown in FIG. 4, when the locomotive body S is switched from the left-leaning state in FIG. 2 to the right-leaning state in FIG. 4, the fill light control member 3 controls the right fill light 22 to perform fill light, and controls the left fill light 21 Stop fill light.

Further, in this embodiment, the two fill light members 2 (that is, the left fill light 21 and the right fill light 22) each include a plurality of light-emitting elements (not shown), and the fill light control member 3 is provided According to the current roll state of the locomotive body S sensed by the inertial measurement unit 1 (degree of inclination of the locomotive body S), the fill light member 2 corresponding to the side of the roll direction is controlled to execute with a corresponding number of light emitting elements Fill light. For example, if the inclination of the locomotive body S is small, only some of the light emitting elements perform fill light; when the inclination of the locomotive body S is large, more light emitting elements perform fill light; when the locomotive body S When the inclination is large to a certain value, all light-emitting elements perform fill-in light. For example, when the angle θ2 of the rolling state of the locomotive body S in FIG. 4 greatly exceeds the tilt angle threshold θ, the number of light-emitting elements performing fill light is greater, so the light of the fill light is brighter than in FIG. 2 . In one example, the light-emitting elements are LED bulbs, which are arranged on the locomotive body S, but the invention is not limited thereto.

Specifically, the fill-light control member 3 has a power regulator (not shown in the drawings of the present invention), and the signal of the power-regulator is connected to the fill-light lamp component 2 for pulse width modulation (PWM, Pulse Width Modulation) Control the fill light member 2 to perform fill light gradually. Of course, the method for controlling the dimming of the fill light member 2 of the present invention is not limited to this. The present invention can also control the fill light by adjusting the resistance of the fill light member 2 by the power regulator The lamp member 2 performs fill light in a gradually brightening manner.

In summary, the corner light supplement safety device 100 of the present invention utilizes the feature that the locomotive body S tilts when the locomotive is cornering, and cooperates with the inertial measurement unit 1 to determine when the locomotive is cornering, so it can be appropriately matched with the corresponding side The inclined fill light member 2 (the left fill light 21 or the right fill light 22) compensates for the light source that the main light cannot illuminate the blind spot, thereby increasing the driving safety of the locomotive when crossing a curve. Furthermore, the present invention can control the fill light member 2 to perform fill light in a gradually brightening manner by adjusting the pulse width or adjusting the resistance of the fill light member 2, thereby avoiding the locomotive driving due to the supplement The situation where the light lamp member 2 is suddenly bright and the vision cannot be adjusted in a short time.
