Description
Technical Field
[0001] The utility model relates to a head-up display for an automobile, and more particularly to an easy-to-install rotating mirror module. Background Art
[0002] Head-up display (HUD), also known as a head-up display system, has gradually shifted from military use to civilian applications with the advancement of technology and its widespread adoption in the automotive sector. In cars, HUD technology projects critical driving information such as vehicle speed, gear position, engine speed, and navigation information onto the windshield in front of the driver's line of sight, allowing the driver to quickly access and process this information without having to look down at the instrument panel. This design not only improves driving convenience but also effectively reduces safety hazards caused by driver distraction.
[0003] Chinese patent publication number CN105759426B discloses an intelligent automotive head-up display device. Its key technical features include: a main unit, a power supply base, and a Bluetooth keypad. The main unit is powered by the power supply base and fixed above the vehicle dashboard. The Bluetooth keypad is fixed to the vehicle steering wheel and connected to the main unit via Bluetooth. The main unit includes a micro-projection light engine, a reflective screen, a concave mirror, a control circuit, and a motor. The control circuit controls the angles of the reflective and concave mirrors via the motor, controlling the micro-projection light engine to project information onto the reflective screen to form an intermediate image. The concave mirror then magnifies the information and displays it on a virtual screen between 1.6 and 10 meters from the driver's seat. The main unit further includes a temperature control device, which includes a fan and a temperature control device built into the micro-projection light engine. The built-in temperature control device regulates the operating temperature of the micro-projection light engine to maintain an optimal operating temperature range of 0°C to 70°C under ambient temperatures of -40°C to +85°C. The fan draws air from above the main unit and exhausts hot air through side outlets on the main unit to help dissipate heat from the main unit.
[0004] In the above technical solution, the installation and disassembly of the concave mirror are relatively complicated and lack convenience, so a new technical solution is needed to solve the above technical problems. Utility Model Content
