Description

Technical Field

[0001] The utility model belongs to the field of detection equipment, in particular to an automatic detection device for automobile pedals. Background Art

[0002] Automobile step-up and down pedals are auxiliary devices designed specifically for SUVs and off-road vehicles. Their primary function is to facilitate boarding and alighting for passengers, especially the elderly and children. These pedals are made of durable metal and can withstand significant pedaling force, enhancing the vehicle's practicality and overall appearance. Currently, automobile pedals primarily consist of a pedal body, an active pedal seat, and a passive pedal seat. The active and passive pedal seats synchronously and parallelly extend and retract the pedal body. Due to the rigidity limitations of the pedal body, the pedal mounting rods of the active and passive pedal seats must be highly synchronized and parallel; otherwise, the pedals will malfunction and become damaged. Therefore, quality inspection of movement synchronization and parallelism is crucial in the production of automobile pedals. However, current automobile pedal movement quality inspections rely primarily on manual inspections, and both accuracy and efficiency need to be improved. Utility Model Content
