Description

Technical Field

[0002] A bicycle, also known as a pedal bike or a cycle, is powered by a user stepping on pedals to move itself and the vehicle body. It is a very green and environmentally friendly means of transportation. Moreover, to ensure the stability and safety of people during cycling, components such as the frame and wheels in the production process of bicycles need to be subjected to corresponding inspections, and relevant inspection equipment is also in a publicly available state. For example, in the authorized patent with the application number 202320705039.8, a battery case size detection device proposes that "the reference component is used to provide a first reference point when detecting the size of the battery case at a predetermined position, and the water inlet and outlet measurement component is used to provide a second reference point when detecting the positions of the water inlet and outlet on the battery case at a predetermined position.
