Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Fig. 2, be a kind of reflector adjusting apparatus 200 that embodiment of the present invention provides, it comprises an optical engine casing 210, one mirror units 220 and a catoptron 240.
Described optical engine casing 210 comprises a bottom surface 211, one advances optical channel 212 and goes out optical channel 213, describedly advance optical channel 212 and go out optical channel 213 vertical settings, and form a sidewall 214 at the described joint that advances optical channel 212 and go out optical channel 213, described sidewall 214 and advance optical channel 212 and go out all to have a certain degree between the optical channel 213 to be obliquely installed.211 contiguous described sidewalls, 214 places, bottom surface of described optical engine casing 210 are provided with first through hole 217 of a circle, and the top 215 of described sidewall 214 is provided with at least two screws 216.
Described mirror unit 220 is fixed on the inboard of described sidewall 214.Described mirror unit 220 is the structure of one similar " Z " shape, and it comprises the first side wall 221, the second sidewalls 222 and the 3rd sidewall 223, and the described the first side wall 221 and second sidewall 222 are positioned at the opposite end of described the 3rd sidewall 223, and extends in the opposite direction.Described the first side wall 221 is stuck in the top of the sidewall 214 of described optical engine casing 210, and adjusting handle 225 and at least two second through holes 226 that are positioned at described adjusting handle 225 both sides are set on the described the first side wall 221.Described second through hole 226 is the class rectangular opening of circular arc for minor face, there are two bolts 230 to pass described second through hole 226 and place described screw 216, therefore when mirror unit 220 is adjusted, bolt 230 is unscrewed, described second through hole 226 can slide along bolt 230.Described second sidewall 222 is used to carry a catoptron 240.The bottom 228 of described second sidewall 222 is provided with the pillar 229 of a circle, and described pillar 229 is corresponding with described first through hole 217 and can be contained in described first through hole 217.Described pillar 229 is a clearance fit with described first through hole 217, and the diameter of promptly described pillar 229 is littler than the diameter of described first through hole 217, thereby described pillar 229 can freely be rotated in described first through hole 217.And described mirror unit 220 can second sidewall 222 bottom 228 carry out slight inclination for axle, thereby can realize adjustment to mirror unit 220.As shown in Figure 3, in the present embodiment, the bottom 228 of described second sidewall 222 is an arc surface, therefore when mirror unit 220 serve as when spool carrying out slight inclination with the bottom 228 of second sidewall 222, described mirror unit 220 is rotating more level and smooth.For the ease of the machine-shaping of described mirror unit 220, be provided with a groove 231 in the bottom 228 of described second sidewall 222, described pillar 229 is positioned at described groove 231.
Described catoptron 240 places on the 3rd sidewall 223 of described mirror unit 220, and the optical surface 241 of described catoptron 240 is towards the inboard of described optical engine casing 210.In the present embodiment, with double faced adhesive tape 242 side relative with optical surface 241 on the described catoptron 240 is bonded on the described mirror unit 220.
The assembling and the adjustment process of described reflector adjusting apparatus 200 are as follows: described mirror unit 220 is put into described optical engine casing 210, described pillar 229 is placed in described first through hole 217, this moment, described second sidewall 222 was towards optical engine casing 210 inside, and the bottom 228 of described second sidewall 222 contacts with the bottom surface 211 of described optical engine casing 210, described the first side wall 221 is towards optical engine casing 210 outsides, and be stuck in the top 215 of the sidewall 214 of described optical engine casing 210, described catoptron 240 usefulness double faced adhesive tapes 242 are fixed on the described mirror unit 220, available then described adjusting handle 225 serves as that axle rotates with mirror unit 220 with described pillar 229, and serve as that a slight inclination takes place axle with the bottom 228 of second sidewall 222, extremely shown in Figure 6 as Fig. 4, thus can realize being fixed on the adjustment of the catoptron 240 on the mirror unit 220.After catoptron 240 is adjusted to suitable position, the bolt 230 that passes described second through hole 226 is locked together with described screw 216, thereby just mirror unit 220 can be fixed on the described optical engine casing 210.
Since the adjusting handle 225 of described mirror unit 220 place described optical engine casing 210 sidewall 214 top 215 and by bolt 230 mirror unit 220 is fixed on the optical engine casing 210, therefore after the assembling of whole projector is finished, once more the position of catoptron 240 is adjusted if need, only need the loam cake (not shown) of projector is removed, then bolt 230 is unscrewed or taken off, utilize adjusting handle 225 to adjust once more the position of described catoptron 240.
Reflector adjusting apparatus of the present invention, carry out the pillar of clearance fit by on mirror unit, being provided with one with first through hole of described optical engine casing bottom surface, can make the catoptron that is fixed on the mirror unit is that axle rotates with the pillar, and is a run-off the straight with the bottom of second sidewall of mirror unit; Catoptron is pasted and fixed on the mirror unit with double faced adhesive tape, and the activity duration is short; Adjusting the back is fixed on mirror unit on the optical engine casing with bolt, can not become flexible, adjusting handle and bolt all are arranged on the top of described optical engine casing simultaneously, only need take the loam cake of projector apart and just can adjust the catoptron that is fixed on the mirror unit, and be convenient and swift.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
