Description
Technical field
The utility model is related to a kind of vehicle-mounted head-up displays, belong to Vehicular display device technical field.
Background technology
Vehicle-mounted head-up display be it is a kind of be imaged using all-transparent or translucent glass, will be with some relevant information of driving a vehicle
A kind of equipment in front of driver's seat is incident upon in a manner of digital picture or word.It is mainly used for allowing driver in driving conditions
In do not have to bow viewing instrument board, so that the sight of driver is always held at vehicle front, with improve driving safety and drive body
It tests.
Existing head up display is broadly divided into following several by image-forming principle：
1 is directly reflective, this kind of mode refers to that head up display is directly placed at below front windshield of vehicle, by coming back
Display shows image, by being imaged after windshield mirror-reflection, imaging scale 1:1.
2 included reflector types, this kind of mode refer to that new line display is placed on reflecting plate rear, are shown and are led by head up display
Machine shows image, is imaged after the baffle reflection placed by direction perpendicular to the ground.Included reflecting plate displaying principle can also be done
It segments below：2.a reflecting plates are plane, and head up display shows that host is placed on reflecting plate rear, and shows the display of host
Screen needs and reflecting plate is close to being placed in parallel, by being imaged after reflecting plate mirror-reflection, imaging scale 1:1；2.b reflecting plate balling-up
Face, head up display show that host is placed on reflecting plate rear, reflect or reflect by multiplex optical system, be ultimately imaged anti-
It penetrates in front of plate, imaging scale is different and different according to optical design.
Wherein, 1 optical system of scheme is most simple, and substantially without optical element, but imaging effect is by vehicle windscreen
It influences, display effect is with regard to different.For example windshield thickness, angle can all influence imaging effect；
Scheme 2.a display sizes and imaging size are 1:1, if imaging size is done sufficiently large, display screen
It needs to do sufficiently large, but should be this mode display screen needs and be disposed vertically, if display screen is too big, the sight meeting of driver
It is blocked；
The direction of scheme 2.b display screens does not limit vertical with reflecting plate, and display screen size can also be designed freely, but be answered
To need multiplex optical to reflect or reflection, the size of entire product is bigger, and complex process；
And scheme 2.a and 2.b are required for showing by addition increasing reflecting plate, but current scheme reflecting plate is all
The front and rear angles for adjusting reflecting plate manually by user oneself, to reach optimal visibility angle, and in vehicle-state flameout state
Lower reflecting plate can not automatically retract.
Utility model content
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of vehicle-mounted head-up displays.
The vehicle-mounted head-up display of the utility model, it includes pedestal, stepper motor, first gear, display screen, support
Seat, second gear and concave mirror, the chassis left side are equipped with display screen, and the chassis interior is equipped with stepper motor,
And first gear is installed on the output shaft of stepper motor, support base is installed on the right side of the pedestal, the support base with
Detaching structure is constituted between concave mirror, and concave mirror is installed above support base, and the support base lower end is equipped with the second tooth
Wheel, and second gear is engaged with first gear.
Preferably, the display screen to concave mirror distance be less than concave mirror one times of focal length, and display screen with it is recessed
Face mirror is placed in parallel.
The beneficial effects of the utility model：Its structure is simple, reasonable design, using concave mirror image-forming principle, eye at this time
The concave mirror that eyeball is seen is imaged as a virtual image upright and that image is shown more than display screen, according to this principle, so that it may with lift
The screen size of head display does small, reduces the size for the sight that is blocked to the greatest extent；It is miniature by increasing by one inside host
Stepper motor drives the shaft rotation of concave mirror bottom as power source, by motor, so as to realize, vehicle igniting, and concave mirror
It is automatically brought to best image position, flame-out back concave surface mirror is recovered to closed position；Concave mirror is doing optimal visibility angle tune simultaneously
When section, same available step motor is adjusted, to improving the convenience and experience sense of user's operation.
Description of the drawings
The utility model is described in detail by following specific implementations and attached drawing for ease of explanation,.
Fig. 1 is the overall structure sectional view of the utility model；
Fig. 2 is the optical schematic diagram of the utility model.
Reference numeral：Pedestal 1, stepper motor 2, first gear 3, display screen 4, support base 5, second gear 6, concave mirror 7,
Concave mirror a, display screen b, display screen real image c, display virtual image d, eyes e.
Specific implementation mode
As Figure 1-Figure 2, present embodiment uses following technical scheme：It includes pedestal 1, stepper motor 2, the
One gear 3, display screen 4, support base 5, second gear 6 and concave mirror 7,1 left side of pedestal is equipped with display screen 4, described
Pedestal 1 inside stepper motor 2 is installed, and first gear 3 is installed on the output shaft of stepper motor 2, the pedestal 1 is right
Side is equipped with support base 5, and 5 top of support base is equipped with concave mirror 7, and dismounting is constituted between the support base 5 and concave mirror 7
Structure, 5 lower end of support base is equipped with second gear 6, and second gear 6 is engaged with first gear 3, the display screen
4 are less than one times of focal length of concave mirror 7 to the distances of concave mirror 7, and display screen 4 is placed in parallel with concave mirror 7, using concave mirror at
As principle, the concave mirror 7 that eyes are seen at this time is imaged as a virtual image upright and that image is shown more than display screen 4.
Present embodiment operation principle is：Using concave mirror image-forming principle, the distance of display screen b to concave mirror a are small
In one times of focal length of concave mirror a, the display screen real image c that eyes e sees is formed by concave mirror a as being amplification, positive
Show virtual image d, and display screen b is in the surfaces concave mirror a and mono- times of focal length of concave mirror a, the nearlyr amplification factor of display screen b focal points
Higher, amplification factor closer from concave mirror a is smaller, until close to concave mirror a, is imaged as 1:1；When work, stepper motor 2 is utilized
Rotate the principle that can be controlled in very little angle, and can persistently slowly run every time, stepper motor 2 and first gear 3,
Under 6 mating reaction of second gear, when stepper motor 2 rotates, drives concave mirror 7 to rotate by support base 5, make concave mirror
7 can be freely rotated in fixed angle, to realize the action of 7 angular adjustment of concave mirror and either on or off, while vehicle-mounted lift
Independent circuit is equipped in head monitor overall, which reads information of vehicles, and is automatically or manually controlled according to information of vehicles
Stepper motor 2 works, and vehicle igniting, concave mirror 7 is automatically brought to best image position, and flame-out back concave surface mirror 7 is recovered to close stance
It sets.
