Problems solved by technology
Most of the existing distance measuring devices are to remind the driver of the car, but cannot remind the driver behind to pay attention. On the expressway, when there are not too many vehicles, it is more wasteful to turn on the warning lights behind, such as anti-fog lights.

Embodiment Construction
[0009] Such as figure 1 Among them, a laser ranging warning light includes a car body 1, a laser range finder 3 is installed behind the car body 1, the laser range finder 3 is electrically connected to the warning light 2, and the laser range finder 3 and the warning light 2 are powered by a battery powered by. The laser rangefinder 3 can detect the distance between the rear and the car. When the distance is too close, for example, when reaching 5 meters, the warning light 2 is turned on and flashes at a rapid speed, thereby reminding the rear driver to keep the distance between cars and avoid rear-end collision.

The invention relates to a laser distance measuring warning lamp, which comprises a vehicle body, wherein a laser distance measuring instrument is arranged behind the vehicle body and is electrically connected with the warning lamp, and the electricity of the laser distance measuring instrument and the warning lamp is supplied by a storage battery. The laser distance measuring warning lamp provided by the invention has the advantages that the laser distance measuring instrument is electrically connected with the warning lamp, the warning on a driver in the vehicle can be realized, the warning on a driver in a rear vehicle can also be realized, and the occurrence of rear-end accidents is avoided.
Description
technical field [0001] The invention relates to an active anti-collision device on a motor vehicle, in particular to a laser ranging warning light. Background technique [0002] When there is heavy fog, the sky is dark or there are many vehicles, accidents such as collisions and rear-end collisions will occur, which will bring great harm to the safe driving of vehicles. Most of the existing ranging devices are to remind the driver of the car, but cannot remind the driver behind to pay attention. On the highway, when there are not too many vehicles, it is more wasteful to turn on the warning lights at the back, such as anti-fog lights. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a laser ranging warning light, which can remind drivers behind to prevent rear-end collisions. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a laser rang...
