Abstract
The utility model discloses a kind of shell stretch mode to open camera lens and the projecting apparatus of switching on and shutting down, including projecting apparatus inner housing, projecting apparatus inner housing front end sets projection lens and infrared induction probe, the front end both sides of projection lens and infrared induction probe set left telescopic shell, right telescopic shell respectively, left telescopic shell, right telescopic shell expose projection lens and infrared induction probe when reversely pulling open, and left telescopic shell, right telescopic shell cover projection lens and infrared induction probe in opposite close.The utility model is by setting scalable shell to open projector lens, while controlling switch machine, to the ceremony sense that beginning is added during user's use, is terminated.Such as the occasion such as meeting, displaying, scalable shell is pulled open, projecting apparatus starts, and meeting ceremony starts.Merge scalable shell, projecting apparatus shutdown, meeting terminates.Its ingenious in design, simple to operate, easy to use, good reliability, cost are relatively low, effectively protect camera lens.
Description
Technical field
Porjector technology field is the utility model is related to, more particularly to a kind of shell stretch mode opens camera lens and switching on and shutting down
Projecting apparatus.
Background technology
Projector lens on the market are typically all to be open in outside at present, and such lens element is easily made dirty or scraped
Flower.To solve this problem, many projector products increase a lens protection set in addition at present.But this protective case operates
It is not strong with the body-sensing of projecting apparatus complete machine one to bother.
Utility model content
In view of the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of shell and stretched
Contracting mode opens camera lens and the projecting apparatus of switching on and shutting down, to solve the deficiencies in the prior art.
To achieve the above object, the utility model provides the projection that a kind of shell stretch mode opens camera lens and switching on and shutting down
Instrument, it is characterised in that：Including projecting apparatus inner housing, the projecting apparatus inner housing front end sets projection lens and infrared induction to visit
Head, the front end both sides of projection lens and the infrared induction probe set left telescopic shell, right telescopic shell respectively, and the left side is stretched
Contracting shell, right telescopic shell expose projection lens and infrared induction probe when reversely pulling open, and the left telescopic shell, the right side are flexible
Shell covers projection lens and infrared induction probe in opposite close.
A kind of above-mentioned shell stretch mode opens camera lens and the projecting apparatus of switching on and shutting down, it is characterised in that：The infrared sense
It should pop one's head in and be provided with infrared discharge lamps and infrared receiver lamp.
A kind of above-mentioned shell stretch mode opens camera lens and the projecting apparatus of switching on and shutting down, it is characterised in that：The infrared sense
It should pop one's head in and be set close to projection lens.
The beneficial effects of the utility model are：
The utility model is made by setting scalable shell to open projector lens, while controlling switch machine to user
Beginning, the ceremony sense terminated are added during.Such as the occasion such as meeting, displaying, scalable shell is pulled open, projecting apparatus opens
Dynamic, meeting ceremony starts.Merge scalable shell, projecting apparatus shutdown, meeting terminates.Its ingenious in design, simple to operate, user
Just, good reliability, cost are relatively low, effectively protect camera lens.
Design, concrete structure and caused technique effect of the present utility model are made furtherly below with reference to accompanying drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Brief description of the drawings
Fig. 1 is projecting apparatus off-mode structural representation of the present utility model.
Fig. 2 is projecting apparatus open state structural representation of the present utility model.
Embodiment
As shown in Figure 1, 2, a kind of shell stretch mode opens camera lens and the projecting apparatus of switching on and shutting down, it is characterised in that：Including
Projecting apparatus inner housing 3, the front end of projecting apparatus inner housing 3 set projection lens 4 and infrared induction probe 5, the projection lens 4
Left telescopic shell 1, right telescopic shell 2 are set respectively with the front end both sides of infrared induction probe 5, the left telescopic shell 1, the right side are stretched
Contracting shell 2 exposes projection lens 4 and infrared induction probe 5 when reversely pulling open, and the left telescopic shell 1, right telescopic shell 2 exist
Projection lens 4 and infrared induction probe 5 are covered when closing in opposite directions.
In the present embodiment, the infrared induction probe 5 is provided with infrared discharge lamps and infrared receiver lamp.
In the present embodiment, the infrared induction probe 5 is set close to projection lens 4.
Operation principle of the present utility model is：
Under off-mode, left telescopic shell 1 and the left and right directions of right telescopic shell 2 are pulled open, expose projection lens 4 and infrared
Inductive probe 5, infrared induction probe 5 is provided with infrared discharge lamps and infrared receiver lamp, when camera lens closed mode, telescopic shell
Infrared ray is reflected, infrared receiver lamp receives infrared signal, and now projecting apparatus is judged as closed mode, and the controller of projecting apparatus closes
Close projecting apparatus；When camera lens open mode, telescopic shell can not reflect infrared ray, and infrared receiver lamp does not receive the infrared of reflection
Signal, now projecting apparatus be judged as open state, the controller of projecting apparatus opens projecting apparatus.
The utility model is made by setting scalable shell to open projector lens, while controlling switch machine to user
Beginning, the ceremony sense terminated are added during.Such as the occasion such as meeting, displaying, scalable shell is pulled open, projecting apparatus opens
Dynamic, meeting ceremony starts.Merge scalable shell, projecting apparatus shutdown, meeting terminates.Its ingenious in design, simple to operate, user
Just, good reliability, cost are relatively low, effectively protect camera lens.
Preferred embodiment of the present utility model is carefully described above.It should be appreciated that one of ordinary skill in the art
Many modifications and variations are made according to design of the present utility model without creative work can.Therefore, all the art
Middle technical staff passes through logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model
Available technical scheme, all should be in the protection domain being defined in the patent claims.
