Description

Head-up display device with curved mirror capable of being manually adjusted

Technical Field

The utility model relates to an auto-parts especially relates to a but curved surface mirror manually regulated's new line display device.

Background

The head-up display device projects important driving information such as speed per hour, navigation and the like onto a windshield in front of a driver, so that the driver can see the driving information without lowering the head or turning the head as much as possible. Head-up display devices have gradually replaced instrument display screens. The AR HUD is an augmented reality heads-up display device that captures and emphasizes pedestrians, vehicles, or road signs on the road through combination with a vehicle radar, a camera, etc., and can also perform early warning on driving safety information.

The adjusting assembly in the existing AR HUD device is driven by a common motor or a stepping motor, a curved mirror is driven to rotate by a gear, a lead screw or a sliding block and other mechanisms, and the travel of the curved mirror is limited by calculating by using a limit switch. The mechanism has the disadvantages that the motor and the limit switch which are electrically adjusted need to be matched with each other through an operation interface, the matched cost is high, and the structural scheme is complex. In addition, because the gear cooperation, structures such as lead screw all have the clearance, and have the vibration in the form in-process, and the curved mirror shake will lead to the formation of image shake to influence and drive experience. Some structures are provided with springs and the like, but the springs have low service life and are easy to cause permanent deformation and failure.

For example, the chinese patent document discloses an "adjustable reflection apparatus and a vehicle-mounted head-up display system", which is under the publication number CN215181159U, and includes a fixed bracket, a curved mirror, and a rotation adjustment device. The rotation adjusting device comprises a base frame with a limit end, a driving piece assembled on the base frame and a transmission seat assembled at the edge position of the curved mirror. The driving piece comprises a gear shaft, and the free end of the gear shaft is rotatably connected to the limiting end. The transmission seat is provided with a tooth pattern surface meshed with the gear shaft, and two limit stoppers are respectively arranged at two ends of the tooth pattern surface along the rotating direction of the curved mirror. The two limit stop blocks are respectively arranged at two sides of the limit end, and in the process that the driving piece drives the transmission seat and the curved mirror to rotate, the two limit stop blocks are respectively matched with the limit ends in an abutting mode so as to limit the transmission seat to move back and forth between the two limit stop blocks. This patent can effectively improve the precision of butt joint between curved mirror and the rotation regulation device for curved mirror is more steady at the rotation in-process, and improves the limit performance of rotation regulation device to curved mirror greatly. However, the disadvantage of this patent is that the vehicle body inevitably vibrates during the running process, and there are many gaps in the gear transmission structure, which can cause the curved mirror to vibrate out of synchronization with the vehicle body, so that the projected picture is continuously jittered relative to the vehicle body, and the view of the driver is affected.
