Abstract
The utility model relates to the field of displays and discloses an image reflection device of a head-up display. The image reflection device comprises at least one reflection mirror, wherein the reflection mirror is used for reflecting a light ray emitted by a projection light source one or more times and amplifying the light ray. The reflection mirror is a planar reflection mirror or a concave reflection mirror. By adopting the image reflection device, the product size can be reduced and the space can be saved while an effect of projection content amplification is achieved.
Description
Technical field
The utility model relates to field of display, particularly a kind of image reflection unit of head-up display.
Background technology
Common projection light source is applied in head-up display, as shown in Figure 1, reach the project content amplification effect, needs to take suitable large space, and namely product structure is larger, is subjected to the more difficult realization of restriction ratio of interior space.
Summary of the invention
The purpose of the utility model embodiment is to provide a kind of image reflection unit of head-up display, adopt present technique to carry out one or many reflection and amplification to described image, when reaching the project content amplification effect, dwindled the volume of product, conserve space.
The image reflection unit of a kind of head-up display that the utility model embodiment provides, comprise at least one catoptron, wherein,
Described catoptron carries out one or many reflection amplification for the light that projection light source is sent.
Alternatively, described catoptron is plane mirror.
Alternatively, described catoptron is concave mirror.
Therefore application the present embodiment technical scheme, because the light that utilizes light transmition and principle of reflection to send projection light source carries out one or many reflection amplification, when reaching the project content amplification effect, dwindled the volume of product.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is that in prior art, common projection light source is applied in the schematic diagram in head-up display;
The image reflection unit schematic diagram of the first head-up display that Fig. 2 provides for the utility model;
The image reflection unit schematic diagram of the second head-up display that Fig. 3 provides for the utility model;
The image reflection unit schematic diagram of the third head-up display that Fig. 4 provides for the utility model;
The image reflection unit schematic diagram of the 4th kind of head-up display that Fig. 5 provides for the utility model;

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
Embodiment:
The image reflection unit of a kind of head-up display that the present embodiment provides, as shown in Figure 2, the image reflection unit of described head-up display comprises a catoptron, wherein,
Can be, but not limited to, described catoptron is plane mirror 2, and the light that 2 pairs of projection light sources 1 of described plane mirror are sent carries out primary event.Perhaps, as shown in Figure 3, described catoptron is concave mirror 3, and the light that 3 pairs of projection light sources 1 of described concave mirror are sent carries out the primary event amplification.
As shown in Figure 4, the image reflection unit of described head-up display comprises two or more plane mirrors 2, and the light that 2 pairs of projection light sources 1 of described plane mirror are sent carries out twice or reflection repeatedly.
Perhaps as shown in Figure 5, the image reflection unit of described head-up display comprises two or more concave mirrors 3, and the light that 3 pairs of projection light sources 1 of described concave mirror are sent carries out twice or reflection is step by step repeatedly amplified.
As shown in Figure 6, the image reflection unit of described head-up display comprises at least one plane mirror 2 and at least one concave mirror 3, and projection light source 1, after level crossing 2 and concave mirror 3 mixed reflections amplifications, produces the reflected image of reflection and amplification.
Therefore the application the technical program, when reaching the project content amplification effect, dwindled the volume of product, saved space.
Above-described embodiment, do not form the restriction to this technical scheme protection domain.The modification of doing within any spirit at above-mentioned embodiment and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of this technical scheme.
Claims (3)
1. the image reflection unit of a head-up display, is characterized in that, comprises at least one catoptron, wherein,
Described catoptron carries out one or many reflection amplification for the light that projection light source is sent.
2. the image reflection unit of a kind of head-up display as claimed in claim 1, is characterized in that, described catoptron is plane mirror.
3. the image reflection unit of a kind of head-up display as claimed in claim 1, is characterized in that, described catoptron is concave mirror.
