Description

Keep off W-HUD device before standing upright

Technical Field

The utility model relates to the field of automobile HUDs (head Up display), in particular to a vertical front windshield W-HUD device.

Background

Currently, the HUDs provided in automobiles are roughly classified into two types: one is a W-HUD projected directly on the front windshield, and the other is a C-HUD with a small flip cover screen at the top of the instrument; two kinds of HUD all adopt projection technique, but when W-HUD was close to vertically preceding windshield in the face of the bus, because preceding windshield is perpendicular to be installed, the eyepoint is higher apart from the driver's cabin, and the glass area can't use the wedge PVB mould to eliminate the ghost image greatly, therefore does not have almost any reflection angle and can image the image in the position that is fit for bus navigating mate eyes. Simultaneously to C-HUD, because of the bus instrument desk is lower, can't place the display content in the suitable position that is close driver's sight the place ahead, consequently HUD does not obtain the application on the bus.

SUMMERY OF THE UTILITY MODEL

The utility model aims to: an upright front windshield W-HUD device is provided for implementing a W-HUD on a bus in an upright front windshield by an optical technical strategy that can be used for the status of the bus upright front windshield.

The technical scheme of the utility model is as follows:

a vertical front windshield W-HUD device comprises a HUD host and an optical diaphragm, wherein the HUD host is arranged on an instrument desk of a whole vehicle, and the optical diaphragm is attached to vertical front windshield glass; the HUD host comprises a host shell, and a HUD signal receiving unit, a HUD image generating unit and a HUD projection mirror which are sequentially connected in the host shell, wherein a HUD reflector is further fixed at the rear end in the host shell; the upper part of the host shell is covered with a curved lens.

Preferably, the HUD signal receiving unit of the HUD host is in communication connection with the whole vehicle instrument; the image that HUD image generation unit produced is projected on the HUD speculum through the HUD projecting mirror, and the HUD speculum reflects the image curved lens on the host computer shell, and curved lens changes the image light path to on the optical film piece on the windscreen before standing upright.

Preferably, the HUD host computer is fixed in whole car instrument desk front portion, HUD host computer top and whole car instrument desk top parallel and level.

Preferably, the included angle between the vertical front windshield and the horizontal plane in the vehicle interior is 85-90 degrees.

Preferably, the longitudinal length of the curved lens on the host shell is 150-200mm, and the transverse width is 90-110 mm.

Preferably, the HUD projection mirror is 60-100 mm away from the lowest point of the whole vehicle instrument desk and 200-300 mm away from the vertical front windshield.

The utility model has the advantages that:

according to the vertical front windshield W-HUD device, the HUD host machine is projected onto the HUD reflector through the HUD projection lens, the HUD reflector reflects an image to the curved lens on the host machine shell, the curved lens converts an image light path to the optical film on the vertical front windshield, a driver can see a corresponding virtual image at a normal driving position, the W-HUD is realized on a bus with the vertical front windshield, the structure is simple, the cost is low, and a good display effect is achieved.

Drawings

The utility model is further described with reference to the following figures and examples:

FIG. 1 is a schematic view of the installation of the upright front windshield W-HUD device of the present invention;

FIG. 2 is a schematic diagram of the external structure of the HUD host of the present invention;

FIG. 3 is a schematic view showing the structure and light path of the vertical front shield W-HUD device of the present invention.

Detailed Description

As shown in fig. 1, the vertical front windshield W-HUD device of the utility model comprises a HUD host 1 and an optical diaphragm 2, wherein the HUD host 1 is installed on a vehicle instrument desk, and the optical diaphragm 2 is attached to a vertical front windshield 3; the included angle between the vertical front windshield and the horizontal plane in the vehicle interior is 85-90 degrees.

As shown in fig. 2 and 3, the HUD host 1 includes a host housing, and a HUD signal receiving unit 11, a HUD image generating unit 12, and a HUD projection mirror 13 which are sequentially connected inside the host housing, and a HUD reflector 14 is further fixed at the rear end inside the host housing; the upper part of the host shell is covered with a curved lens 15. The HUD signal receiving unit 11 of the HUD host 1 is in communication connection with the whole vehicle instrument; the image generated by the HUD image generating unit 12 is projected onto the HUD mirror 14 through the HUD projection lens 13, the HUD mirror 14 reflects the image onto the curved lens 15 on the main body casing, and the curved lens 15 converts the image optical path onto the optical diaphragm 2 on the upright windshield 3.
