Test tool for HUD (head up display) motor assemblies

Abstract

The invention discloses a test tool for HUD (head up display) motor assemblies. The test tool comprises a bottom plate, a positioning device, a test device and a clamping device. The bottom plate is horizontally arranged, the positioning device and the test device are arranged on the top surface of the bottom plate, the clamping device is arranged on the positioning device, the positioning devicecomprises a second connecting plate, a first positioning block, a second positioning block and a first positioning pin, the second connecting plate is vertically fixed to the bottom plate by the aid of a first connecting plate, the first positioning block, the second positioning block and the first positioning pin are fixedly arranged on an end surface of the same side of the second connecting plate, a second positioning pin is convexly arranged on an end surface of the side, which is far away from the second connecting plate, of the second positioning block, the test device is arranged on a first side, which is far away from the first positioning block, of the second connecting plate, the clamping device comprises quick pincers and an air cylinder, the quick pincers are arranged on the second connecting plate via a third connecting plate, the air cylinder is arranged on the second connecting plate via a fourth connecting plate, and the quick pincers and the air cylinder are arranged on the side, which is far away from the test device, of the second connecting plate. The test tool for the HUD motor assemblies has the advantage that diversified properties can be simultaneously tested by the test tool.

[0002] The vehicle-mounted head-up display device is an information display system applied to mid-to-high-end cars. It is installed above the driver's dashboard and consists of a multimedia projection system, a driving actuator and a protective cover opening and closing mechanism. Among them, the protective cover opening and closing mechanism drives the motor assembly. Components are referred to as HUD motor components, see figure 1 ; The existing DC motor tester is mainly used to test the worm gear type miniature low-voltage DC motor, and the mechanical transmission mechanism suitable for the motor assembly has a self-locking function, and the motor assembly is a simple motor transmission function without signal feedback function; while the HUD motor The component has a torque clutch function and a position signal output function. At the same time, the travel switch of the motor needs to be detected, so it is necessary to detect the motor speed, torque, current function, torque clutch function and position signal output function at the same time
