[0001] The utility model relates to the technical field of vehicle measurement, in particular to a vehicle outer dimension measuring device. Background Art

[0002] Vehicle size refers to the restrictions on the overall height, overall width and overall length of the vehicle. Vehicle height: the distance between the highest point of the vehicle and the vehicle's support plane; Vehicle width: the distance between planes parallel to the vehicle's longitudinal symmetry plane and respectively against the outermost rigid fixed protrusions on both sides of the vehicle; Vehicle length: the distance between two vertical lines that are perpendicular to the vehicle's longitudinal symmetry plane and respectively against the outermost protrusions at the front and rear of the vehicle.

[0003] In the prior art, when measuring the vehicle's external dimensions, manual measurement is mostly performed using measuring instruments such as a level ruler and an electronic plumb bob, which is not only time-consuming and labor-intensive, but also has insufficient measurement accuracy and low measurement efficiency. Therefore, we have introduced a vehicle external dimension measuring device. Utility Model Content
