Vehicle external contour length and wheelbase measuring apparatus for vehicle check station

Abstract

The invention discloses a vehicle external contour length and wheelbase measuring apparatus for a vehicle check station. The vehicle external contour length and wheelbase measuring apparatus is characterized in that a track is arranged on one side edge on the ground of a parking area and is parallel to the advancing direction of a vehicle, a moving vehicle is arranged on the track through wheels, which are connected with a transmission mechanism, and the transmission mechanism is connected with a stepping motor which is connected with a controller. A laser range finding scanner is connected on the moving vehicle, the laser range finding scanner and the controller are respectively connected with a first wireless communication module, a storage battery is arranged in the moving vehicle, and the storage battery is respectively connected with a laser range finder, the controller and the first wireless communication module. A charging pile is arranged on the starting end of the track, a fixed charging interface is arranged in the charging pile, and a mobile charging interface aligning with the fixed charging interface is arranged in the moving vehicle. The first wireless communication module is wirelessly connected with a second wireless communication module, and the second wireless communication module is connected to a main machine body. The vehicle external contour length and wheelbase measuring apparatus saves space, and has the advantages of high measurement precision and high efficiency.

Description

technical field [0001] The invention relates to a vehicle testing equipment, in particular to a vehicle profile length and vehicle wheelbase measuring device at a vehicle testing station. Background technique [0002] With the progress of society, cars have become an indispensable means of transportation for social production and family life, and the number of vehicles is increasing day by day. Every car must be tested regularly according to the regulations. According to the motor vehicle safety technical performance testing standard GB21861- In 2014, it was required to detect the length of the vehicle outline and the wheelbase of the vehicle. When the existing detection stations detect the length of the vehicle and the wheelbase of the vehicle, they are all measured by the vehicle passing through at a constant speed. The detection equipment is fixed, and the vehicle is required to drive at a lower speed. And pass through the testing equipment at a constant speed, it is diff...

[0002] With the progress of society, cars have become an indispensable means of transportation for social production and family life, and the number of vehicles is increasing day by day. Every car must be tested regularly according to the regulations. According to the motor vehicle safety technical performance testing standard GB21861- In 2014, it was required to detect the length of the vehicle outline and the wheelbase of the vehicle. When the existing detection stations detect the length of the vehicle and the wheelbase of the vehicle, they are all measured by the vehicle passing through at a constant speed. The detection equipment is fixed, and the vehicle is required to drive at a lower speed. And pass through the testing equipment at a constant speed, it is difficult to control the speed of driving a large vehicle during the actual detection, resulting in a serious discrepancy between the measurement result and the actual vehicle length, insufficient stability, and large actual errors, and the constant speed passing measurement requires a long time for the site; still to be done technical solution
