Description
Technical field
The present invention relates 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.
Invention content
In view of the above-mentioned problems, the technical problem to be solved in the present invention is to provide a kind of vehicle-mounted head-up displays.
The vehicle-mounted head-up display of the present invention, it includes pedestal, stepper motor, first gear, display screen, support base, the
Two gears and concave mirror, the chassis left side are equipped with display screen, and the chassis interior is equipped with stepper motor, and stepping
First gear is installed on the output shaft of motor, support base is installed on the right side of the pedestal, and is equipped with above support base recessed
Face mirror, the support base lower end is equipped with second gear, and second gear is engaged with first gear.
Preferably, constituting detaching structure between the support base and concave mirror.
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.
Beneficial effects of the present invention：Its structure is simple, reasonable design, and using concave mirror image-forming principle, eyes are seen at this time
To concave mirror be imaged as a virtual image upright and that image is shown more than display screen, according to this principle, so that it may with aobvious coming back
It is small to show that the screen size of device is done, reduces the size for the sight that is blocked to the greatest extent；By increasing a miniature stepping inside host
Motor drives the shaft rotation of concave mirror bottom as power source, by motor, and so as to realize, vehicle is lighted a fire, and concave mirror is automatic
Best image position is gone to, flame-out back concave surface mirror is recovered to closed position；Simultaneously concave mirror when doing optimal visibility angular adjustment,
Same available step motor is adjusted, to improve the convenience and experience sense of user's operation.
Description of the drawings
The present invention 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 present invention；
Fig. 2 is the optical schematic diagram of the present invention.
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
