投射式顯示裝置之安全帽Projection display device hard hat

本創作係有關於一種安全帽，尤指一種投影至少一資訊到擋風罩上顯示之安全帽。This creation is about a helmet, especially a helmet that projects at least one information onto the windshield.

習知的安全帽技術如美國專利號5646784揭示一種安全帽顯示系統，具有一面甲設在該安全帽上，一全像組合器(holographic combiner)形成在該面甲上，安全帽內設有兩個影像投影器投影影像在該面甲上的全像組合器上，然後藉由該全像組合將該投影影像反射到穿戴者的雙眼，穿戴者的雙眼也可透過面甲看到外界。另一習知的安全帽例如Skully公司的Skully AR-1，美國專利公開號20130305437A1，係在安全帽內加入抬頭顯示器（HUD）且內建GPS導航及後置鏡頭，穿戴者除了可如一般安全帽通過面罩看到身體前方的外在環境，並可以通過抬頭顯示器看到身體後方的環境，以及通過抬頭頭顯示器看到GPS導航資訊。由上述習知技術可知在安全帽增加顯示的功能已經是一種趨勢，但是如何善用安全帽內的空間設置顯示裝置又能達到不影響行車視線是本領域之人所要努力的方向。A conventional hard hat technology, such as U.S. Patent No. 5,646,784, discloses a helmet display system having a side arm mounted on the helmet, a holographic combiner formed on the visor, and two in the helmet. An image projector projects an image on the hologram combiner on the visor, and then the projected image is reflected to the wearer's eyes by the omnidirectional combination, and the wearer's eyes can also see the outside through the visor . Another conventional safety helmet such as the Skully AR-1 of the Skully Company, US Patent Publication No. 20130305437A1, incorporates a head-up display (HUD) in a helmet and has built-in GPS navigation and a rear lens, in addition to being safe as a wearer. The cap sees the external environment in front of the body through the mask, and can see the environment behind the body through the head-up display, and see the GPS navigation information through the head-up display. It is known from the above-mentioned prior art that the function of increasing the display of the helmet has been a trend, but how to make good use of the space setting display device in the helmet can achieve the direction that the person in the field does not affect the driving sight.

As shown, a helmet body 11 defines a headwear space 12 for a wearer's head to wear. The front side of the helmet body 11 defines a line of sight 13 corresponding to the wearer's eye area, and the helmet body 11 has a helmet forehead portion 112 on the upper side of the line of sight window 13 corresponding to the wearer's forehead area, and a helmet. The chin portion 114 corresponds to the wearer's chin surrounding area on the lower side of the line of sight window 13. The line of sight window 13 is connected to the head wearing space 12, an upper edge 131 of the line of sight window 13 is adjacent to the helmet forehead portion 112, and the lower edge 132 of the line of sight window 13 is adjacent to the helmet chin portion 114. A reflecting unit 21 is disposed on the lower edge 132 of the line of sight window 13. The reflecting unit 21 is preferably a mirror having a reflecting surface 211 facing the upper edge 131 of the line of sight window 13. A projection unit 22 is disposed on the upper edge 131 of the line of sight window 13. The projection unit 22 is preferably a projector for transmitting at least one optical signal, and has a projection end 221 facing the lower edge 132 of the line of sight window 13 . The projection end 211 is a reflection surface 211 corresponding to the reflection unit 21. A windshield 14 is disposed at the sight window 13 and is movable to cover the sight glass window 13. The windshield 14 is made of a transparent material so that the wearer's eye sight can be seen through the windshield 14 In the external environment and driving route, the windshield 14 also protects the wearer's eyes from wind and rain. In particular, the reflecting unit 21 disposed at the lower edge 132 of the line of sight 13 has its reflecting surface 211 slightly inclined toward the windshield 14, and the windshield 14 defines a display area 141 on which the projection end 221 of the projection unit 22 is launched. The optical signal is emitted from the upper edge 131 of the line of sight window 13 to the lower edge 132 of the line of sight 13 and then reflected by the reflecting surface 211 of the reflecting unit 21 to be projected onto the display area 141 to display the optical signal image. The image of the optical signal projected by the projection unit 22 is superimposed/fused with the scene outside the windshield 14 to make the optical image appear to be farther in front of the wearer (for example, in front of the windshield 14). The virtual image appearing at 3-5 meters reduces the line of sight movement and focus adjustment of the wearer's eyes to produce a natural visual effect. The wearer can simultaneously see the light signal image and the road ahead to improve driving safety. Please continue to refer to Figure 4 for a schematic diagram of this creative implementation. As shown in the figure, referring to the foregoing first to third figures, when the wearer (or driver) 31 wears the helmet body 11 on the head, the head of the wearer 31 is located in the head wearing space 12. Since the reflection unit 21 is disposed at the lower edge 132 of the line of sight window 13 and the projection unit 22 is disposed at the upper edge 131 of the line of sight window 13, the reflection unit 21 and the projection unit 22 do not occupy the head wearing space 12 The helmet body 11 of the present creation has a sufficient head wearing space 12 to accommodate the head of the wearer 31. Furthermore, the light signal emitted from the projection end 221 of the projection unit 22 is from the upper edge 131 of the line of sight window 13 to the lower edge 132 of the line of sight window 13 and then reflected by the reflective surface 211 of the reflection unit 21 to be projected thereon. The display area 141 displays the optical signal image, and the projected reflection path of the optical signal image avoids interference with the line of sight 312 of the eye 311 of the wearer 31, and the optical signal image is reflected by the reflection unit 21 and projected onto the display area 141, and then The line of sight 312 of the wearer 31 is displayed again, so that the projected image of the light signal is superimposed with the scene outside the windshield 14 to make the optical image appear at a farther position, reducing the eyes of the wearer 31. The line of sight movement and focus adjustment produce a natural visual effect. In summary, the present invention provides the projection unit 22 and the reflection unit 21 in the helmet body 11 in a small space by the above structure, without affecting the head wearing space 12, and avoiding interference to the driving line of sight, and The image of the optical signal projected by the projection unit 22 is superimposed/fused with the scene outside the windshield 14 to make the optical image appear at a farther position, reducing the line of sight movement and focus adjustment of the eyes of the wearer 31. A natural visual effect. While the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and the scope of the present invention can be varied and modified without departing from the spirit and scope of the invention. The scope of the patent application is subject to the provisions of the attached patent application.
