Abstract
The utility model discloses a mini-type projector capable of automatically adjusting a projection direction, comprising a shell and a central processing unit arranged inside the shell. The mini-type projector capable of automatically adjusting the projection direction further comprises a gravity sensor arranged in the shell; and the gravity sensor is connected with the central processing unit in a communication manner. The mini-type projector capable of automatically adjusting the projection direction adopts the gravity sensor, so that the mini-type projector which inversely or vertically placed can normally project, and further an application field of the mini-type projector is expanded and the flexibility is strong.
Description
Technical field
The utility model relates to a kind of projector apparatus, relates in particular to a kind of micro projector that can automatically adjust projecting direction that changes projecting direction.
Background technology
For micro-projector 10, because the occasion of its use is changeable, therefore just might make its modes of emplacement that multiple variation is arranged, and unlike can only normally lie on the worktable shown in the accompanying drawing 1, projection is projected on the vertical wall 20, use to have obtained restriction.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of micro projector that can automatically adjust projecting direction is provided.
For achieving the above object, the described micro projector that can automatically adjust projecting direction, comprise housing and be arranged at the interior central processing unit of housing, be characterized in, the described micro projector that can automatically adjust projecting direction also comprises the gravity sensor that is arranged in its housing, and described gravity sensor is connected with described central processing unit communication.
The beneficial effects of the utility model are, the described micro projector that can automatically adjust projecting direction adopts gravity sensor, but makes the micro projector normal projection of being inverted or vertically placing, thereby has widened the application scenario of this micro projector, and dirigibility is stronger.
Description of drawings
Fig. 1 shows the projection pattern synoptic diagram of conventional projector.
Fig. 2 shows and uses the micro projector that can automatically adjust projecting direction described in the utility model, the perspective view when it is in inverted state.
Fig. 3 shows and uses the micro projector that can automatically adjust projecting direction described in the utility model, the perspective view when it is in the state of vertical placement.
Fig. 4 shows the functional-block diagram that can automatically adjust the micro projector of projecting direction described in the utility model.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 4, the described micro projector 10 that can automatically adjust projecting direction, comprise housing, be arranged at the central processing unit 11 in the housing and the little throwing module 12 that is connected with described central processing unit 11 communications, the described micro projector 10 that can automatically adjust projecting direction also comprises the gravity sensor 13 that is arranged in its housing, and described gravity sensor 13 is connected with described central processing unit 11 communications.
Perspective view when micro projector 10 is inverted and is vertically placed as described in showing respectively such as Fig. 2 and Fig. 3, when it is inverted, being arranged at gravity sensor 13 in its shell will work as the modes of emplacement of front projector 10 and transfer to central processing unit 11, making the projection light source of output turn over turnback by central processing unit 11 controls, is normal thereby make the image that is projected on the wall 20.When micro projector 10 is in the state of vertical placement, being arranged at gravity sensor 13 in its shell will work as the modes of emplacement of front projector and transfer to central processing unit 11, by central processing unit 11 controls the projection light source of output being turned over turn 90 degrees or 270 degree, is normal thereby make the image that is projected on the wall 20.
Being the utility model preferred embodiment only in sum, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to technology category of the present utility model.
