Vehicle lamp projection system based on millisecond wave radar

Abstract

The invention discloses a vehicle lamp projection system based on millisecond wave radar, one side of a vehicle lamp projection device is provided with a projection lamp device, the projection lamp device comprises a projection lamp, one end of the projection lamp is fixedly provided with a C-shaped frame, two ends of the C-shaped frame are fixedly provided with rectangular frames, adjacent side surfaces of the rectangular frames are respectively fixedly provided with a first stress block and a second stress block, and the first stress block and the second stress block are connected with the projection lamp. A first telescopic rod is fixed to the lower end of the first stress block, a second telescopic rod is fixed to the lower end of the second stress block, wedge-shaped blocks are fixed to one end of the first telescopic rod and one end of the second telescopic rod, the horizontal ends of the wedge-shaped blocks are fixed to one side of the vehicle lamp projection equipment, and a cross-shaped rod is rotationally connected to the inner wall of the rectangular frame. The two long ends of the cross-shaped rod are rotationally connected with the inner walls of the two sides of the rectangular frame, Y-shaped rods are fixed to the two short ends of the cross-shaped rod, and one end of each Y-shaped rod is fixed to one side of the automobile lamp projection equipment. The millimeter wave radar sends out electric signals to control the first telescopic rod and the second telescopic rod to stretch out and draw back, so that the projection direction of the projection lamp is changed, the projection range can be effectively widened, informatization interaction between vehicles and between vehicles and pedestrians is promoted, and the practicability of the projection lamp is improved.

Description

technical field [0001] The invention relates to the field of vehicle lamp projection, in particular to a vehicle lamp projection system based on millisecond wave radar. Background technique [0002] As the driving assistance system of the vehicle, the lamp projection system can realize the information interaction between vehicles and between vehicles and pedestrians. [0003] The system is used for vehicles to detect pedestrians or other vehicles around them through millimeter-wave radar at night, and the relevant driving signs are projected on the road surface by the projector lamp, which is convenient for prompting pedestrians and other vehicles, thereby improving the safety of traffic driving. [0004] However, when the current vehicle lamp projection system is driving on an uphill road, since the direction of the projection lamp cannot be adjusted, the projected picture cannot be projected on the road, the function of the projection lamp will be invalid, and better infor...

Problems solved by technology

[0004] However, when the existing car light projection system is driving on an uphill road, because the projection lamp cannot adjust the direction, the projected image cannot be projected on the road surface, the function of the projection lamp will be invalid, and better information interaction cannot be achieved. , when the picture projected by the projection lamp is just projected on the pedestrian's face, the projected light will directly hit the pedestrian's eyes, which will affect the pedestrian's safe walking
