Abstract

A detection device for the noise and current of automobile electric seat includes the automobile seat loading test table, sport controller, sensor and signal processor. The automobile seat loading test table and sensors are set in the isolation booth; the sport controller and signal processor are set in the controlling ark out of the isolation booth. The system can fix the automobile seat automatically and load the simulating human load, controls each electric engine run and detect the noise and electric engine current to judge if it meets the request and print the product test table. The character of invention is high automatization, standardization and accuracy measurement. The whole detection process is finished automatically; the each test load is identical with the action journey and accord with the detection condition. It detects the current and noise precisely and remove the artificial subjective factors to meet the request of quality management.

Description

technical field [0001] The invention relates to a detection device in the field of mechanical technology, in particular to a detection device for noise and motor current of an electric seat of an automobile. Background technique [0002] Electric seats are commonly used in mid-to-high-end cars, that is, the motor is controlled by buttons to adjust the seat's lifting, front and rear, left and right movement, backrest pitching and other actions. In the production of this kind of electric seat, it is necessary to inspect the noise generated by the motor movement and the motor current. The former is mainly the requirement for the comfort of the car environment, and the latter is the inspection of the motor performance and assembly process to prevent the use of defective products. The motor may be damaged due to excessive resistance caused by improper assembly. In the previous production, manual inspection was adopted, that is, the inspector manually operated the seat movement, ...
