Abstract

The present invention relates to a separate head-up display device, an adhesive paste set on a bottom side of the base of a display module is provided to adhere on a windshield, to reduce shakes that a reflective sheet of a reflective sheet adjustment module is fixed on the dashboard and the windshield, and rotary joint structures are further set between the display module and the reflective sheet adjustment module, so that a driver may easily adjust the direction of the reflective sheet to obtain an optimal viewing angle, to thereby improve driving safety.

Claims

1. A separate head-up display device, including:

a display module, which includes a display unit, a base and a circuit board, the display unit electrically connected to the circuit board is provided to receive images output from the circuit board and project images;

a reflective sheet adjustment module, which includes a reflective sheet, a base plate, a support arm and a sliding element, the sliding element is selectively connected to and moveable along the base plate, a first joint unit and a third joint unit are connected to a side of the reflective sheet, a second joint unit is connected to a side of the base plate, the second joint unit and the first joint unit are engaged together to form a first rotary joint;

the support arm, a fourth joint unit is connected to a front end of the support arm, a fifth joint unit is set on a rear end of the support arm, the fourth joint unit and the third joint unit are engaged together to form a second rotary joint;

the sliding element, a sixth joint unit is connected to a front end of the sliding element, the sixth joint unit and the fifth joint unit of the support arm are engaged together to form a third rotary joint;
