Problems solved by technology

In this method, although the variable magnification lens assembly and the image quality compensation lens assembly can be used to adjust the size of the displayed image, the system will be too complicated, and the front stop compensation lens assembly will also increase the design and processing difficulty and cost of the system.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.

[0024] see figure 1 with figure 2 , figure 1 is a schematic diagram of the first embodiment of the vehicle-mounted information projection system of the present invention, figure 2 It is a schematic diagram of the second embodiment of the vehicle-mounted information projection system of the present invention, figure 1 The system shown is placed in front of the driver when in use, figure 2 The system shown is suspended in front of the driver when in use. It can be seen from the figure that a vehicle-mounted information projection system includes a vehicle status micro-display system 1, a micro-projection system 2, a scattering plate 3 and a half-mirror 4. The positional relationship of the above components is as follows:

[0025] The micro-projection system 2 images t...

Abstract

The invention relates to a vehicle-carried information projection system. The vehicle-carried information projection system comprises an automobile state micro display system, a micro projection system, a scatter plate and a semi-transmitting semi-reflecting lens, wherein the micro projection system images information displayed on the automobile state micro display system onto the scatter plate, the semi-transmitting semi-reflecting lens forms a virtual image of the image on the scatter plate to an infinite long distance or a finite long distance, and the virtual image seen by human eyes is at a position having a certain distance to an automobile windscreen. The structure of the vehicle-carried information projection system can be very small, the cost is low, the flexibility is greater and the feasibility is stronger; no windscreen compensating mirror component is needed and the design and manufacturing difficulty is small; by using the scatter plate as a relay surface, the trance and dizziness caused to the human eyes are weakened, the intensity of light emitted by the automobile state micro display system is very high, after relay imaging through the scatter plate, the light emitted by the automobile state micro display system does not directly enter the human eyes and thus the displayed image seen by the human eyes is softer.

Description

technical field [0001] The invention relates to the field of vehicle-mounted information display, in particular to a vehicle-mounted information projection system adaptable to any vehicle type. Background technique [0002] When driving a car, the driver needs to look down at the dashboard or navigator frequently to judge the car's speed, fuel consumption, engine speed, car driving route and other information. This line of sight is frequently switched between the dashboard and the road ahead. Different driving modes increase the risk factor of driving. In order to avoid the frequent switching of the driver's line of sight and at the same time not prevent the driver from obtaining the vehicle's driving status information in a timely manner, the information projection system is applied to the field of vehicle information display. The vehicle information projection system integrates the vehicle's status information into the front scene through the optical system , the driver c...
