Abstract
The utility model discloses a kind of vehicle-mounted head-up display, including pedestal, projector is set on the pedestal, reflecting mirror is set in front of projector, convex lens is equipped between the projector and reflecting mirror；The light of projector is reflexed to concave mirror by reflecting mirror, and the reflecting surface of the concave mirror reflexes to windshield towards windshield, and by light, and light enters human eye after windshield reflects；The concave mirror is fixed by the bracket on the base, and concave mirror and bracket are articulated and connected.Vehicle-mounted head-up display provided by the utility model realizes device miniaturization, allows system as far as possible from windshield, not because thickness of glass generates ghost image, concave mirror adjustable angle, to adapt to the demand of different vehicle, different drivers.
Description
Technical field
The utility model relates to a kind of vehicle-mounted head-up displays, belong to vehicle electronic device technical field.
Background technique
Vehicle-mounted head-up display (Head Up Display, abridge HUD) projects to running information in front of driver, drives
Information needed can be obtained without bowing in the person of sailing, to improve traffic safety.
In terms of information angles of display, HUD can be divided into real image show and the virtual image show two kinds.The former shows smaller screen in the car
Curtain posts on the windshield of Special Film, and the latter appears in the outer front of vehicle, i.e., one nearly one is remote.It normally drives in making, driver
Sight is generally gathered in road ahead, if to see that nearby real image HUD information, gesture necessary adjustment ocular focusing still have at the moment
Some potential safety problems, and it be easy to cause eye fatigue.Therefore, running information is projected in front of driver, and is normally driven
It sails middle range of observation to be overlapped and merge, driver is both not necessarily to bow, and will not cause additional fatigue, be ideal HUD scheme.
Currently, more common in preceding dress market, rear dress market is more rare because virtual image type HUD volume is larger.
Utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of vehicle-mounted head-up display.
Technical solution: in order to solve the above technical problems, the technical solution adopted by the utility model is:
A kind of vehicle-mounted head-up display, including pedestal are provided with projector on the pedestal, setting reflection in front of projector
The light that projector issues is reflexed to concave mirror by mirror, reflecting mirror, and the reflecting surface of the concave mirror is towards windshield, and by light
Windshield is reflexed to, light enters human eye after windshield reflects；The concave mirror is fixed by the bracket on the base, recessed
Face mirror and bracket are articulated and connected.
Further, convex lens is equipped between the projector and reflecting mirror, for shortening the minimum focusing of projector
From so that the volume of the entire vehicle-mounted head-up display of diminution, achievees the effect that HUD is minimized.
Further, the projector is low-light level micro projector.
Further, the reflecting mirror is greater than one times of focal length of concave mirror at a distance from concave mirror, less than the two of concave mirror
Times focal length, to obtain the image of amplification.
Further, the concave mirror is connect with bracket by universal joint, can arbitrarily adjust the angle of concave mirror, with suitable
Answer different vehicle, the visual angle of different drivers and comfort level demand.
Further, the reflecting mirror deviation pedestal perpendicular bisector is inclined outwardly certain angle.
Further, tilt angle is 14 ~ 15 °.
The utility model has the advantages that vehicle-mounted head-up display provided by the utility model, for providing running information for driver.It is throwing
Convex lens is set between shadow instrument and reflecting mirror, the minimum focal distance of projector can be shortened, so that the volume of whole system is reduced,
Achieve the effect that HUD is minimized；Concave mirror will not interfere driving backwards to driver, and concave mirror is far from windshield, no
Stay ghost image；The focal length of concave mirror be F, reflecting mirror at a distance from concave mirror between F and 2F, to obtain enlarged drawing；Concave mirror
It is articulated and connected with bracket, the adjustable angle of concave mirror, to adapt to different vehicle, the visual angle of different drivers and comfort level demand.
Detailed description of the invention
Fig. 1 is the optical schematic diagram of the utility model；
Fig. 2 is the schematic perspective view of the utility model；
Fig. 3 is the side structure schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of vehicle-mounted head-up display, including pedestal 1, pedestal 1 can be printed by 3D three-dimensional printing machine
It forms.The pedestal 1 is equipped with projector 2, and reflecting mirror 4 is arranged in front of projector 2, and reflecting mirror 4 reflects the light of projector 2
To concave mirror 5, the reflecting surface of the concave mirror 5 reflexes to windshield towards windshield 6, backwards to driver, and by light
6, light enters human eye after the reflection of windshield 6, and driver is it is seen that the upright virtual image.
Convex lens 3 is equipped between the projector 2 and reflecting mirror 4.Because projector design is that remote projection image uses,
Its minimum focal distance is generally large, is greater than 15cm；And after using convex lens, minimum focal distance can reduce 6cm, whole
The anteroposterior dimension of system can also reduce 6cm.The projector 2 is low-light level micro projector, projector choosing in the present embodiment
Select 1500 lumens.
The reflecting mirror 4 is greater than one times of focal length of concave mirror at a distance from concave mirror 5, less than the two focus length of concave mirror.
The reflecting mirror 4 deviates 1 perpendicular bisector of pedestal and tilts certain angle, and tilt angle is 14 ~ 15 °.
The concave mirror 5 is fixed on pedestal 1 by bracket 7, and concave mirror 5 and bracket 7 are articulated and connected；Specifically, concave surface
Mirror 5 is connect with bracket 7 by universal joint 8, can arbitrarily adjust the angle of concave mirror, the universal joint is by a pair of of relative bearing
It is formed for 90 ° of common hinges.
Finally, head-up display provided by the utility model can make image in front of the driver at 2m, and with front 15-
The fusion of the road surface 20m takes into account the comfort of observation and drives range of observation.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
