ActiveCN122085036AEven by forceControllable forceElectrical testingMaterial strength using steady bending forcesLiquid-crystal displaySpray nozzle
This invention discloses a testing device and method for liquid crystal display modules, relating to the field of liquid crystal display module testing technology. The device includes a base, a flipping bracket, a housing, and a testing platform. The testing platform is equipped with a bidirectional clamping device driven by a first motor for automatically clamping the liquid crystal display module for bending resistance testing, and an auxiliary bending mechanism to ensure uniform force distribution. The housing also houses a click-resistance testing mechanism, including an electric hammer, a pressure sensor, and a displacement sensor, for testing the screen's resistance to click pressure. After testing, debris is automatically removed by a multi-stage cleaning mechanism including a scraper and a spray nozzle. When the testing platform flips, the spray nozzle moves closer to the testing platform to improve the cleaning effect. This invention features a high degree of automation, integrating bending resistance testing and click testing, providing accurate testing and thorough cleaning, effectively improving the efficiency and safety of liquid crystal display module mechanical performance testing.

Control method, device and vehicle for contactless pinch protection of a vehicle window
This disclosure relates to a control method, device, and vehicle for contactless anti-pinch protection of vehicle windows, including: acquiring spatial motion status parameters of an obstacle relative to an onboard radar sensor on the window closing path, and obtaining the real-time position of the obstacle based on the spatial motion status parameters; generating movement parameters of the obstacle based on the real-time position at multiple time points; determining whether the obstacle meets threat conditions based on the spatial motion status parameters and movement parameters, wherein the threat conditions are used to characterize the risk of the obstacle being pinched; and triggering the window to perform anti-pinch operation when it is determined that the obstacle meets the threat conditions. This disclosure relies on the non-contact active sensing characteristics of radar, actively emitting electromagnetic waves for detection. Tens to hundreds of milliseconds before the glass and obstacle collide, the radar has already detected the obstacle's intrusion path, thereby achieving pre-collision intervention. This represents a technological upgrade from traditional passive motor load detection to active spatial sensing, allowing for early risk detection without physical contact with the obstacle.
