Drive systems for Head-up Display

ZHAOWEI flip drive system can be applied to the design and customization of the head-up display flip screen gearbox. The flip gearbox is connected to the support frame. The motor drives the entire HUD screen flip mechanism to rotate around the center of rotation, thereby driving the HUD screen to rotate. The flip angle of the screen can be intelligently controlled to meet the display needs of users of different heights.

The head-up display can map important information, such as driving speed, water temperature, etc., on the holographic half mirror on the windshield, so that the driver can see the important information clearly without looking down. The head-up display is to improve people’s driving safety factor. However, some head-up displays on the market also have some bugs. During driving, the angle of the head-up display is inappropriate, and the information displayed on the display cannot be seen in a normal sitting posture, which affects driving safety.

Through the analysis of the structure of the head-up display flip screen, we find that there are two sets of transmission routes, which are fulfilled by the reversing effect of the reversing mechanism on the support of the display. One set of the transmission routes is the input shaft, the reversing mechanism, and the forward gear train. The other is the input shaft, the reversing mechanism, the reverse gear train, and the output gear. When the forward gear train participates in the transmission, the output gear rotates forward. When the reverse gear participates in the transmission, the output gear will rotate reversely. The output gear steering can be achieved through the conversion of the above two sets of transmission routes, so as to avoid excessive load and damage to the gear, and stabilize the head-up display angle during driving. It improves safety during driving.

The gearbox for the head-up display flip screen has two-stage, three-stage, and four-stage transmission changes. The reduction ratio, input speed, and torque of the gearbox can be altered and adjusted according to the transmission demand.

Characteristics of Gearbox for HUD Flip Screen
