Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 and Fig. 2 shows in the back side wall 110, figure of buildings plenum, and the left side of back side wall 110 is the outside of interlayer, and the right side of back side wall 110 is the inside of interlayer.Because the inner space of buildings plenum is limited, enough displacement is obtained in order to make the projector in interlayer, in the utility model, back side wall 110 is provided with perforate 113, thus the projector originally in interlayer can be moved out to outside interlayer.
According to the portable projection arrangement of the utility model one embodiment comprise pair of guide rails 11,12, chain-drive mechanism, locomotive 3, projector 4, first detecting sensor 51, second detecting sensor 52, clamshell doors 6, clamshell doors driving mechanism, enabling detecting sensor 81, detecting sensor of closing the door 82, input media 9 and controller 10.
Wherein, pair of guide rails 11,12 is through perforate 113, and a part for guide rail 11,12 is positioned at the inside of plenum, and another part is then positioned at the outside of plenum, and this pair of guide rails is fixed on the ceiling of buildings by grape trellis 13.Chain-drive mechanism comprises drive sprocket 21, driven sprocket 22, the chain wheel drive motor 23 driving drive sprocket 21 to rotate and the chain 24 of winding on this drive sprocket and driven sprocket.Locomotive 3 is fixed on chain 24, and is provided with two pairs of wheels 31,32 that can roll in pair of guide rails.Locomotive 3 can move between the primary importance preset and the default second place along pair of guide rails 11,12; Wherein, primary importance is positioned at the inside of buildings plenum, and the second place is positioned at the outside of buildings plenum.Projector 4 is suspended in the below of locomotive 3 by many chain slings 41, thus can follow locomotive 3 and move together.Whether the first detecting sensor 51 moves to described primary importance for detecting locomotive 3, whether the second detecting sensor 52 moves to the described second place for detecting locomotive 3, in the embodiments illustrated in the figures, the first detecting sensor 51 and the second detecting sensor 52 are limit switch.
Shown in composition graphs 3 and Fig. 4, clamshell doors 6 comprises the doorframe 60 be arranged in back side wall and a pair door leaf 61,62 be arranged on doorframe 60.In a specific embodiment, doorframe 60 is arranged on the lateral surface of back side wall 110.A pair door leaf 61,62 is relative with the back side of projector 4 when closed, and has partly covered perforate 113, thus the personnel in buildings be can't see be in the projector 4 of primary importance, to keep the aesthetics of interior of building environment.Clamshell doors driving mechanism comprises a pair electric pushrod 71,72 for driving this pair door leaf 61,62 folding correspondingly respectively.Whether enabling detecting sensor 81 is opened for detecting a pair door leaf 61,62, and whether detecting sensor of closing the door 82 closes for detecting a pair door leaf 61,62.In the embodiments illustrated in the figures, this enabling detecting sensor 81 and detecting sensor 82 of closing the door are limit switch.
Shown in composition graphs 5.Input media 9 is for receiving the operational order of outside input, and input media 9 can be keyboard, mouse or touch-screen.The signal input part of controller 10 is connected with the signal output part of the signal output part of the signal output part of the first detecting sensor 51, the second detecting sensor 52, the signal output part of enabling detecting sensor 81, the signal output part of detecting sensor of closing the door 82 and input media 9 respectively, and the control output end of this controller 10 is connected with the control input end of the control input end of chain wheel drive motor 23 and the drive motor 711,721 of a pair electric pushrod respectively.Controller 10 can be such as single-chip microcomputer.
The course of work of the present utility model is as follows:
Under normal conditions, projector 4 is positioned at the primary importance shown in Fig. 1, and now, a pair door leaf 61,62 is in closure state, is equivalent to projector 4 to be hidden in plenum.When the image projected on projection screen from the camera lens 42 of projector 4 is too small, when needing to regulate the projection distance between projector and projection screen, operating personnel input regulating command by input media 9, after controller 10 receives regulating command, control electric pushrod drive motor 711 and electric pushrod drive motor 721 start, the expansion link of electric pushrod 71,72 is protruding, promotes a pair door leaf 61,62 and outwards rotates.When a pair door leaf 61,62 outwards rotate 90 °, be in door opening state time, door leaf 61 touches enabling detecting sensor 81, and enabling detecting sensor 81 generation one that is triggered is opened the door detection signal send to controller 10.After controller 10 receives this enabling detection signal, control electric pushrod drive motor 711 and electric pushrod drive motor 721 quit work, and Quality Initiative wheel drive motor 23 rotates clockwise, so locomotive 3 is moved to the second place along pair of guide rails 11,12 by primary importance.When locomotive 3 moves to the second place by primary importance, locomotive 3 touches the second detecting sensor 52, second detecting sensor 52 and to be triggered generation one second place detection signal send to controller 10.After controller 10 receives this second place detection signal, Quality Initiative wheel drive motor 23 stops operating.In this second place, the image projected projection screen from the camera lens 42 of projector 4 can than large in primary importance.After projector completes projection work, operating personnel input reset command by input media 9, after controller 10 receives reset command, Quality Initiative wheel drive motor 23 rotates counterclockwise, so locomotive 3 is moved to primary importance along pair of guide rails 11,12 by the second place.When locomotive 3 moves to primary importance by the second place, locomotive 3 touches the first detecting sensor 51, first detecting sensor 51 and to be triggered generation one primary importance detection signal send to controller 10.After controller 10 receives this primary importance detection signal, Quality Initiative wheel drive motor 23 stops operating, and controlling electric pushrod drive motor 711 and electric pushrod drive motor 721 starts, the expansion link of electric pushrod 71,72 is retracted, and drives a pair door leaf 61,62 inwardly to rotate.When a pair door leaf 61,62 is in closure state, door leaf 61 touches detecting sensor 82 of closing the door, and detecting sensor of closing the door 82 generation one that is triggered is closed the door detection signal send to controller 10.After controller 10 receives this detection signal of closing the door, control electric pushrod drive motor 711 and electric pushrod drive motor 721 quit work, and now, projector 4 is hidden in again in plenum.
