Description

Technical Field

[0001] This utility model belongs to the field of automotive parts testing technology, specifically an automated seat testing device. Background Technology

[0002] With economic and social development, automobiles are becoming increasingly intelligent. As the most important and complex interior component of a car, the comfort requirements for car seats are also rising. Features such as 12-way power adjustment, seat ventilation, heating, automatic memory, lumbar support adjustment, and seat massage have become standard equipment in mid-range and higher-end sedans. These functions require a large number of circuits and control devices to be encased inside the seat, so all functions of the seat need to be tested after production.

[0003] Current automotive seat inspection suffers from the following pain points: High reliance on manual labor: Traditional inspection relies on manual operation of each item, which is inefficient and prone to errors; Incomplete functional coverage: It is difficult to simultaneously inspect comprehensive items such as mechanical performance (e.g., durability of dummy buttock pressure), electrical functions (button response, ECU communication), and optical indicators (ambient light spectrum); Poor compatibility: The inspection fixtures need to be frequently adjusted for different car models, resulting in insufficient flexibility.

[0004] Application No. 2017201349150 discloses a fully automated automotive seat electrical inspection device based on robots, including an electrical control cabinet, an automatic docking mechanism, a seat motion detection mechanism, a seat function and SBR (Self-Rating Blowering) detection mechanism, and an equipment frame. This patent solution uses an industrial robot to replace humans. However, mid-to-high-end passenger car seats integrate complex button controls, requiring various finger movements to adjust the buttons, making the solution in this patent unsuitable. Furthermore, the seats integrate welcome light strips, requiring detection of the strip's color and brightness uniformity, which this patent solution cannot achieve. The SBR detection mechanism needs to simulate the downward pressure of a human buttocks, requiring precise force control and simulating multiple different force compressions. Different car models have different pressure points, requiring the detection mechanism to change positions to accommodate these variations, all of which this patent solution cannot achieve. The automatic docking mechanism in this solution can only use specific seats and cannot be universally applicable. Its mechanical structure occupies a large space, and the working area of ​​the industrial robot needs to be completely enclosed, making human-robot collaboration impossible. Utility Model Content
