The mounting housing 1 is fixed at the front or rear of the vehicle, and the light source 2, the lens group 3 and the controller 4 are all mounted in the mounting housing 1; the lens group 3 is arranged at one end of a light outlet of the light source 2, the light source 2 and the controller 4 are both fixed on the side wall of the installation shell 1, and the light source 2 is connected with the controller 4 and a sensor of the vehicle; the sensor comprises a speed sensor, a steering wheel angle sensor, a steering lamp switch sensor, a brake lamp switch sensor, a windshield wiper switch sensor, a fog lamp switch sensor, a GPS positioning module, a camera and the like; the light emitting direction of the lens group 3 is inclined relative to the running direction of the vehicle, so that the light beam emitted by the light source 2 can be projected onto the lane where the vehicle is located through the lens group 3, and a light ray mark corresponding to the lane line is formed, thereby improving the problem that the lane fog lamp cannot directly project sufficient light onto the lane line, and the lane departure or the collision risk with other vehicles occurs under the conditions of fog days or other low visibility.

Referring to fig. 1 to 4, a mounting housing 1 for mounting respective components includes a mounting housing 11 and a globe housing 12; wherein the mounting housing 11 comprises a mounting cavity 111, the light source 2, the lens group 3 and the controller 4 are fixed in the mounting cavity 111; the globe case 12 is provided at one end of the mounting case 11 and covers the mounting cavity 111. After the light source 2, the lens group 3 and the controller 4 are all fixed in the installation cavity 111, the light source 2, the lens group 3 and the controller 4 are sealed in the installation cavity 111 by the lampshade shell 12, so that the light source 2, the lens group 3 and the controller 4 are effectively prevented from being influenced by external factors such as rainwater, fog and dust, and normal operation of the lane fog lamp is ensured.

Referring to fig. 1 to 4, the lens group 3 includes a convex lens 31 and a concave lens 32, the convex lens 31 and the concave lens 32 being fixed to an inner wall of the mounting housing 11, the convex lens 31 corresponding to the light outlet of the light source 2, one end of the concave lens 32 corresponding to the convex lens 31, and the other end of the concave lens 32 corresponding to the globe housing 12; an air layer is formed between the convex lens 31 and the concave lens 32, a group of rotating lens groups 33 with adjustable angles are arranged in the air layer, the rotating lens groups 33 are connected with the controller 4, and the controller 4 controls the angle change of the rotating lens groups 33 according to the projection direction and the shape of the light beams emitted by the light source 2, so that the focusing and projection positions of the light beams after passing through the lens groups 3 are changed; the lens group 3 is used for converting the light beam emitted by the light source 2 into a required light mark through optical processes such as reflection, refraction, scattering and the like, and projecting the light mark onto a lane where a vehicle is located.

Referring to fig. 1 to 4, the rotary mirror set 33 includes a mirror 331, a connection ring 332, and a rotation table 333, the connection ring 332 is fixed on a rotation plane of the rotation table 333, the mirror 331 is fixed on the connection ring 332, and the rotation table 333 is connected with the controller 4, so that the rotary mirror set 33 can achieve angle adjustability. The controller 4 changes the focusing and projecting position of the light beam after passing through the lens group 3 by controlling the rotation of the rotation table 333 according to the projecting direction and shape of the light beam to change the angle of the reflecting mirror 331. Such an adjustment mechanism can ensure that the beam is projected onto the lane in which the vehicle is located, forming a light mark corresponding to the lane line. By flexibly adjusting the angle of the reflecting mirror 331, the lane fog lamp can accurately project the light mark to the correct position according to different running states and surrounding environments. For example, when the vehicle is traveling a curve or changing a lane, the controller 4 may adjust the angle of the reflecting mirror 331 according to the signal of the steering wheel angle sensor or the turn signal switch sensor so that the projection direction and shape of the light beam are consistent with the actual lane line.

Specifically, when the visibility is greater than 200 meters, the controller 4 turns off the light source 2, and does not project any light mark; when the visibility is less than or equal to 200 meters, the controller 4 turns on the white or yellow low-brightness light source 2 to project a dotted line mark with the same width and interval as the actual lane line; when the visibility is less than or equal to 100 meters, the controller 4 turns on the white or yellow medium-brightness light source 2 and projects a solid line mark with the same width and interval as the actual lane line; when the visibility is 50 meters or less, the controller 4 turns on the red or orange high-brightness light source 2 and projects a solid line mark wider and denser than the actual lane line. The color, the brightness and the shape of the light mark are automatically adjusted according to different visibility, so that the light mark is matched with an actual lane line, and the recognition and the adherence of a driver to the lane line are improved.

When the vehicle is running on a curve or changing the road, the controller 4 adjusts the projection direction and shape of the light beam according to the signals of the steering wheel angle sensor or the turn signal switch sensor, so that the light mark is consistent with the actual lane line. For example, in a left turn, the controller 4 deflects the light beam to the left and projects a left curved dashed or solid line mark; in a right turn, the controller 4 deflects the light beam to the right and projects a dotted or solid mark of the right curve; when changing the lane, the controller 4 moves the light beam leftwards or rightwards, and projects a dotted line or a solid line mark corresponding to the target lane line, so that the mark is consistent with the actual lane line, and the judgment and response of the driver on the road condition are improved.

When the vehicle is braked, the controller 4 increases the brightness and the flicker frequency of the light beam according to the signal of the brake light switch sensor to warn the vehicle behind. For example, when braking, the controller 4 causes the light beam to turn red or orange, and to blink at a higher frequency, and to project a solid line mark that is the same as or wider than the actual lane line, giving it a stronger warning effect, thereby improving the attention and avoidance of the rear vehicle to the front vehicle.

Referring to fig. 1 to 4, in order to facilitate the connection and fixation of the installation housing 11 with the front or rear of the vehicle, a connection block 112 is provided on the outer wall of the installation housing 11, and a lane fog lamp may be conveniently installed at the front or rear of the vehicle by providing a screw hole on the connection block 112; meanwhile, the connection block 112 may be matched to the structure of the vehicle, for example, connected to a front bumper or a rear bumper of the vehicle. Through fixed connection, the lane fog lamp can be stably installed on the vehicle and cannot be influenced by vibration or jolt in the running process of the vehicle.

Referring to fig. 1 to 4, the light source 2 may be an LED lamp, a laser lamp or other light sources 2 capable of emitting different colors, brightness and shapes, and the selection and adjustment of these light sources 2 can realize the clarity, vividness and accuracy of the light marks according to different usage scenes and environments.

The implementation principle of the lane fog lamp provided by the embodiment of the application is as follows: the lane fog lamp comprises a mounting housing 1, a light source 2, a lens group 3 and a controller 4. The mounting housing 1 is fixed at the front or rear of the vehicle, the light source 2 is disposed in the mounting housing 1, the lens group 3 is disposed in front of the light source 2, and the controller 4 is connected with the light source 2 and the sensors of the vehicle.

The controller 4 controls the light source 2 to emit light beams of different colors, brightness and shapes according to the driving state of the vehicle and the visibility of the surrounding environment detected by the sensor, and projects the light beams onto a lane where the vehicle is located through the lens group 3 which is obliquely arranged relative to the driving direction of the vehicle, thereby forming a light ray mark corresponding to the lane line.

The controller 4 controls the light source 2 to emit light beams of different colors, brightness and shapes according to the driving state of the vehicle and the visibility of the surrounding environment detected by the sensor, and focuses and projects the light beams onto the lane where the vehicle is located through the lens group 3 to form a light ray mark corresponding to the lane line.

The controller 4 controls the light source 2 to emit light beams of different colors, brightness and shapes according to the driving state of the vehicle and the visibility of the surrounding environment detected by the sensor, and focuses and projects the light beams onto the lane where the vehicle is located through the lens group 3 to form a light ray mark corresponding to the lane line.

When the vehicle is running on a curve or changing the road, the controller 4 adjusts the projection direction and shape of the light beam according to the signals of the steering wheel angle sensor or the turn signal switch sensor, so that the light mark is consistent with the actual lane line. For example, in a left turn, the beam is deflected to the left and a left curved dashed or solid line mark is projected; when turning right, the light beam deflects right and projects a dotted line or a solid line mark of right bending; at the time of lane change, the light beam is moved to the left or right, and a broken line or a solid line mark corresponding to the target lane line is projected.

When the vehicle is braked, the controller 4 increases the brightness and the flicker frequency of the light beam according to the signal of the brake light switch sensor to warn the vehicle behind. For example, at the time of braking, the light beam is made red or orange, and blinks at a higher frequency, and the solid line mark that is the same as or wider than the actual lane line is projected.
