Compression resistance detection device for vehicle-mounted display screen

By using a control assembly consisting of a drive unit, a servo motor, and a reset spring, the contact rod can be adjusted bidirectionally. This solves the problem that existing testing devices cannot cover the critical areas of the display screen, enabling full-area pressure resistance testing and providing accurate pressure resistance performance assessment.

AI Technical Summary

Technical Problem

Existing vehicle display testing devices cannot fully simulate the pressure resistance performance in multiple directions and angles, especially in key areas such as the edges and corners of the screen, resulting in blind spots and making it impossible to fully assess the actual pressure resistance performance of the display.

Method used

The control assembly, which combines a pressure sensor output by a drive unit with a servo motor and a return spring, enables bidirectional adjustment of the touch lever, covering the entire display area, including edges and corners, to simulate multi-directional force scenarios.

Benefits of technology

It enables full-area pressure resistance testing of vehicle-mounted displays, eliminates blind spots in testing, provides accurate pressure resistance performance evaluation data, and ensures the authenticity and validity of the test data.

Abstract

The utility model relates to the technical field of display screen detection, and discloses a pressure resistance detection device for a vehicle-mounted display screen, which comprises a detection machine, a top driving piece for providing stable pressure applying power, a workbench clamping piece for fixing the display screen, and a pressure sensor at the output end of the driving piece, the pressure value of contact between the feeler lever and the display screen can be obtained in real time, the accuracy of detection data is guaranteed, and a foundation is laid for compressive property evaluation. The control assembly realizes bidirectional adjustment of the feeler lever, one side of the moving seat is connected with a reset spring, the other side of the moving seat is wound with a winding roller of a servo motor, and the servo motor winds and unwinds the stay wire to be matched with the reset spring to drive the moving seat to reciprocate in the direction; a threaded roller between the two moving seats is driven by a driving machine, the moving table is slidably sleeved on a fixed sliding rod, the sliding rod is limited to enable the moving table to translate along the rod and drive the feeler lever to synchronously move, the feeler lever can flexibly cover the whole area of a display screen through bidirectional adjustment, and detection blind areas of key parts such as edges and corners are eliminated.
