Description

Optical imaging device with projection positioning

Technical Field

The present invention relates to an optical imaging device, and more particularly, to an optical imaging device with projection positioning.

Background

Head Up Display (HUD) devices are popular in airplanes and in home vehicles such as automobiles. In order to increase the driving safety of automobiles, the simple information prompt of the old HUD cannot meet the driving requirements of automobiles. Through the display technology of Augmented Reality (AR) HUD, more safety information can be provided for drivers such as: the information such as the distance between the vehicle ahead of the driver, lane deviation, lane change prompt and the like is overlapped and displayed with the road state (such as road marking, vehicle, pedestrian or sign and the like) seen by the driver, so that the practicability of the information is increased, the striking degree is expressed, and the driving safety is improved.

As shown in fig. 1, when a driver looks at a road condition from the inside of the vehicle to the outside, the horizontal line of the eyes extends outward to reach an infinite distance (the first horizontal line of sight LH1 and the second horizontal line of sight LH2 shown in fig. 1), inclines downward by 1 degree from the horizontal line of the eyes (the first inclined line of sight L11 and the second inclined line of sight L12 shown in fig. 1), extends outward to reach a distance of about 50 to 55 meters, inclines downward by 7 degrees from the horizontal line of the eyes (the third inclined line of sight L31 and the fourth inclined line of sight L32 shown in fig. 1), extends outward to reach a distance of about 6 to 8 meters, the AR HUD is designed to satisfy safe and clear display information, the vertical field of view is set to incline downward by 1 degree from the horizontal line of the eyes by 7 degrees from the starting point to the horizontal line of the eyes, and the vertical field of view of about 6 degrees and the horizontal field of view of about 12 degrees of the cover are used as the display range for enhancing the real environment with the prompting information.

However, as shown in fig. 1, different heights and driving postures of different drivers may cause different vision differences, i.e. the first eye1 of one driver and the second eye2 of another driver correspond to different sight heights, which causes the covered areas of vision to be greatly different. As shown in fig. 2, the first optical projecting element M1 can project onto the first projection area a1 on the windshield W, and if the image information reflected by the first projection area a1 is viewed by the first eye1, the image information cannot be correctly displayed in an overlapping manner with the road state due to the difference in the height of the line of sight when the image reflected by the first projection area a1 is viewed by the second eye 2.

Although the position of the first projection area a1 can be changed by adjusting the angle of the optical projection element M1 to adjust the image height, for example, chinese published patent application No. CN106461948A discloses a similar HUD image adjustment method, the angle of the optical projection element M1 projecting the image onto the windshield W is changed when the angle of the optical projection element M1 is adjusted, and this adjustment method cannot satisfy the precise angle limitation that the AR HUD needs to display the image and the road state in an overlapping manner, and is not suitable for the AR HUD. On the other hand, although the chinese patent application CN106458059A discloses a method for automatically adjusting HUD images, it must be implemented through a plurality of detectors and seat actuators, which are complex structures, and limits the driving posture of the driver, which obviously does not meet the market demand.

In summary, the present invention provides an optical imaging device with projection positioning for positioning the visual field of the driver by providing an optical imaging device, which can adjust the position of the housing for drivers with different heights, so that the image projected by the optical projection component can accurately fall into the visual area of the driver.

In addition, referring to fig. 4C, the third and fourth bases LGT22 and LGS22 are also disposed as the first and second bases LGT12 and LGS12, the center points of the third and fourth light-emitting pieces LGT24 and LGS24 are also the same as the first and second light-emitting pieces LGT14 and LGS14, a third distance D3 and a fourth distance D4 are respectively disposed between the center points of the third and fourth light-emitting pieces LGT24 and LGS24 and the second side wall 144, the third distance D3 is greater than the fourth distance D4, so that a second center distance D2 is disposed between the center points of the third and fourth light-emitting pieces LGT24 and LGS24 to prevent the third positioning light ray 3 generated by the third light-emitting piece LGT24 from being blocked by the fourth base 539s 22. In addition, the first distance D1 and the third distance D3 may have the same length or different lengths, and the second distance D2 and the fourth distance D4 may have the same length or different lengths. The first base LGT12 and the second base LGS12 are both protruded on the first sidewall 142 along the X direction, and referring back to fig. 3E, a Y direction interval DY is provided between the first base LGT12 and the second base LGS12, and the third base LGT22 and the fourth base LGS22 are also the same as the arrangement manner of the first base LGT12 and the second base LGS12, and therefore, the description thereof is omitted. The Y direction may be perpendicular to the X direction, and the Y direction may be a projection direction of the optical projection assembly 164.

As shown in fig. 4D, the optical imaging device 10 further includes a control circuit CTR electrically connected to the display 18, the driver 20, the first positioning light-emitting device LGT1, the second positioning light-emitting device LGS1, the third positioning light-emitting device LGT2 and the fourth positioning light-emitting device LGS2, and further electrically connected to the first auxiliary light-emitting device LG1, the second auxiliary light-emitting device LG2, the third auxiliary light-emitting device LG3 and the fourth auxiliary light-emitting device LG 4.

Furthermore, as shown in fig. 5A to 5C, the display 18 of the optical imaging device 10 of the present invention generates the image IMG to be reflected to the optical projection element 164 along the reflection path RF by the reflector 162, so that the image IMG is projected according to a visual optical path P1, the angle θ between the visual optical path P1 and the linear direction of the housing 14 when moving is kept constant, and after the projected image IMG is reflected by the windshield W, a reflective optical path P2 is formed, which corresponds to the visual optical path P1, and the first eye1 and the second eye2 with different visual heights have corresponding visual optical paths P1 and reflective optical path P2, so that after the optical imaging device 10 is moved linearly, the meridians can be projected to the corresponding first visual region V1 and second visual region V2 in the first projection region a1 and the second projection region a2 respectively, so that the first eye1 can see the projected image IMG in the first visual region V1, the second eye2 can see the projected image IMG in the second visual region V2.

In the present embodiment, the positioning manner corresponding to the first eye1 is exemplified, as shown in fig. 6A to fig. 6C, it is assumed that the first positioning light emitting element LGT1 and the second positioning light emitting element LGS1 are overlapped in the driver's sight line, so that the positioning optical path P3 represents the positioning light rays L1, L2 with overlapped positions, and the positioning light rays L1, L2 with overlapped positions travel along the positioning reflection path P4 after being reflected by the windshield W, whereas as shown in fig. 6B, the positioning reflection path P4 does not fall into the first visual region V1 corresponding to the first eye1, that is, the positioning light rays L1, L2 are outside the first visual region V1, and thus the first eye1 cannot see the positioning light rays L1, L2 with overlapped positions in the first visual region V1.

At this time, the first light P32 generated by the first positioning light emitting element LGT1 at other angles and the second light P34 generated by the second positioning light emitting element LGS1 at other angles are projected on the first projection area a1 and enter the first visual area V1, so that the first eye1 can see the light spots corresponding to the first positioning light emitting element LGT1 and the second positioning light emitting element LGS1 in the first visual area V1. Therefore, the driver corresponding to the first eye1 can know that the image IMG projected by the optical imaging device 10 will be projected outside the first visual area V.

As shown in fig. 6C, after the driver adjusts the positioning, the driver 20 adjusts the position of the housing 14 so that the light spots corresponding to the first positioning light-emitting assembly LGT1 and the second positioning light-emitting assembly LGS1 overlap. At this time, the positioning optical path P3 is overlapped with the visual optical path P1, so the drawing only indicates the positioning optical path P3 to indicate that the positioning optical path P1 is overlapped with the visual optical path P1, and the positioning reflective path P4 is also overlapped with the reflective optical path P2, so that the first eye1 can see the overlapped positioning light beams L1 and L2 in the first visual area V1, so that a driver corresponding to the first eye1 can know that the image IMG projected by the optical imaging device 10 is projected into the first visual area V. The positioning method corresponding to the second eye2 is the same as the positioning method of the first eye1, and therefore, the positioning of the second eye2 is not described in detail.

In addition, the first auxiliary light R1 and the second auxiliary light R2 generated by the first auxiliary light emitting device LG1 and the second auxiliary light LG2 respectively can also enter the first visual area V1 to form a light spot in the eyes of the driver, so as to assist the driver to determine the direction in which the housing 14 needs to be adjusted, and further assist the driver to quickly adjust the light spots corresponding to the first positioning light emitting device LGT1 and the second positioning light emitting device LGs1 to overlap through the driver 20. On the other hand, the first positioning light emitting assembly LGT1 and the second positioning light emitting assembly LGS1 may have different colors of light; alternatively, the first auxiliary light emitting device LG1 and the second auxiliary light emitting device LG2 and the first positioning light emitting device LGT1 and the second positioning light emitting device LGs1 may have different colors of light, which can effectively assist the driver to identify the direction of the housing 14 to be adjusted.

Please refer to fig. 7A to 7C, which are a perspective view, another perspective view and a side view of an optical imaging device according to another embodiment of the present invention. The difference between fig. 3A to 3C and fig. 7A to 7C lies in that the first sliding-connection portion 122a of the first moving part 122 and the second sliding-connection portion 124a of the second moving part 124 shown in fig. 3A to 3C are in a linear direction, the first connecting member 142a and the second connecting member 144a of the housing 14 are correspondingly disposed on the first sliding-connection portion 122a of the first moving part 122 and the second sliding-connection portion 124a of the second moving part 124, the first moving part 222 having a first curved sliding-connection portion 222b and the second moving part 224 having a second curved sliding-connection portion 224b shown in fig. 7A to 7C are in a non-linear direction, and the rest of the first sliding-connection portion 222a and the rest of the second sliding-connection portion 224a are still in a linear direction. In addition, the driver 30 is connected to the slider 32 through the driving shaft 302, the slider 32 slides on the sliding member 246, and the sliding member 246 is pivoted to the housing 24 through the pivot member 248.

As shown in fig. 7A to 7C, since the windshield may be not only a horizontal plane but also a curved plane, in order to match the curved windshield, a first curved sliding-contact portion 222b of the first moving member 222 and a second curved sliding-contact portion 224b of the second moving member 224 are in a non-linear direction and further form a curved direction, so that the corresponding first curved connecting member 242b and second curved connecting member 242b on the housing 24 move in the curved direction when the driver 30 drives the sliding member 246 through the rotation of the driving shaft 302.

As mentioned above, the driving shaft 302 is disposed through the sliding block 32, the sliding block 32 is slidably disposed on the sliding rail 264a of the sliding member 246, so that when the driver 30, the first moving member 222 and the second moving member 224 are fixed, one side of the housing 24 where the sliding member 246 is disposed will move in a curved direction along with the movement of the first curved connecting member 242B and the second curved connecting member 244B, so as to allow the housing 24 to move in a curved direction in addition to the linear movement, and further move in a curved direction to adjust the projection angle of the optical projection assembly 16, so as to project the optical image corresponding to the curved windshield, as shown in fig. 8A and 8B, when the driving shaft 302 is rotated by the driver 30, the optical imaging device 10 will move in the first curved moving direction C1, so that the first curved moving direction C1 corresponds to the curvature of the curved windshield Wa, and when the optical imaging device 10 moves in the second curved moving direction C2, the second curved moving direction C2 corresponds to the curvature of the curved windshield Wa.

In summary, the optical imaging device with projection positioning of the present invention is configured to arrange a plurality of positioning light-emitting components on the sidewall of the housing, and generate a plurality of positioning lights through the plurality of positioning light-emitting components, so that the driver can refer to the positioning lights and correctly adjust the image projected by the positioning optical imaging device to the visual area. Thus, the optical projection component of the invention can be used for projecting images to visual areas with different visual heights. In addition, the optical projection component of the invention can also be designed with a moving mechanism corresponding to a plane or curved windshield, so that the shell can move towards a preset direction corresponding to the style of the windshield. Therefore, the optical projection assembly can meet the requirement of an AR HUD on accurate angle limitation of overlapping display of an image and a road state, and can meet the design requirement of the AR HUD without arranging a sensor with higher cost or a complex adjusting mechanism.

As is apparent from the above description, the present invention has achieved a breakthrough in structure, improved aspects, industrial applicability and advancement, and is in accordance with the provisions of the patent laws.
