Description
Technical field
The utility model relates to a kind of projector more particularly to a kind of novel projectors that projecting direction is changeable.
Background technique
Projector is also known as projector, is a kind of equipment that can be projected image or video on curtain, can be by not
The equipment such as the same computer of interface together, DVD, which are connected, plays corresponding vision signal.Projector is divided into front projection type by projection pattern
Projector (focal length) and rear projector for projecting (short focus), the most important difference in the structure of the two are setting for projection lens
Seated position and direction difference.Projector is widely used in family, office, school and public place of entertainment.Existing projector includes
Projector main body；Projector main body includes shell, electric circuitry packages, optical module, Inclination maneuver supporting element and projection lens,
Electric circuitry packages and optical module are generally located in enclosure interior, and Inclination maneuver supporting element is generally located in the preceding bottom of shell, throw
Shadow camera lens is generally located in housing side.But in family's application process, inventors have found that there are some for existing projector
The projecting direction of defect, exactly existing projector is not adjustable, and only projection lens first side can only when needing to change direction
Mobile whole projector.For example, some people like recumbency in bed and see when putting projection in the family, need to arrive image projecting
On ceiling, at this time, it may be necessary to whole projector is holded up to place, and when general projector design, it usually lays flat, erects
Using very inconvenient when putting.In addition, the projection orientation position of projector and the adjustment at inclination angle, need by adjusting Inclination maneuver
The height of supporting element is realized, is not very convenient to use.
Utility model content
It is to solve existing projector there are drawbacks described above, the utility model, which provides, a kind of facilitates people to watch with different gestures
The novel projector of influence.
To achieve the above object, the scheme that the utility model is taken is: a kind of changeable projection imaging angle and direction
Novel projector, including projector main body；Projector main body includes shell, electric circuitry packages, optical module and projection lens,

Instrument ontology；For front projection type projector main body, shell is front side in projection lens side, and shell front side bottom, which is equipped with, prolongs
Long portion, lens supports are rotationally hinged on extension front end by hinged shaft, cut with scissors between lens supports and extension for tight fit
It connects；For rear projector for projecting ontology, the housing parts opposite with its projection lens are rear-projection side, and lens supports can by hinged shaft
It is rotationally hinged on rear-projection side, it is hinged for tight fit between lens supports and rear-projection side.Tight fit can hingedly make reflecting mirror
It follows lens supports to fix in arbitrary tilt angle, realizes multi-direction projection.
As the further improvement of the first above-mentioned improvement project, aforementioned extension or rear-projection side are equipped with driving eyeglass branch
The minitype speed reducing motor of frame rotation, the output end and stud connection of minitype speed reducing motor.
As second of improvement of above scheme, aforementioned projection instrument ontology is front projection type projector main body, and shell is projecting
Camera lens side is front side, and housing bottom is equipped with the expansion bracket of free extension on front side of shell, and lens supports can be turned by hinged shaft
It is hinged on expansion bracket front end dynamicly, it is hinged for tight fit between lens supports and expansion bracket.Tight fit can hingedly make reflecting mirror
It follows lens supports to fix in arbitrary tilt angle, realizes multi-direction projection.Lens supports may be folded on by hinged shaft
On expansion bracket, and expansion bracket can be followed to be accommodated in shell.
As the improvement of above-mentioned second of improvement project, aforementioned expansion bracket includes articulated section, flexible slide bar and flexible drive
Motivation structure, articulated section setting are arranged in housing bottom, telescoping drive mechanism in shell in flexible slide bar front end, flexible slide bar setting
In vivo, flexible slide bar drives it to stretch out or retract out of shell by telescoping drive mechanism.
As the further improvement of above-mentioned second of improvement project, the articulated section of aforementioned expansion bracket is equipped with driving eyeglass branch
The minitype speed reducing motor of frame rotation, the output end and stud connection of minitype speed reducing motor.
As the improvement of above-mentioned two kinds of improvement projects, predicate lens bracket is equipped with the eyeglass card slot for placing reflecting mirror, institute
Reflecting mirror is stated to be removably disposed in eyeglass card slot.By eyeglass card slot, different reflecting mirrors is replaced with can be convenient, it is such as flat
Exchange between face reflecting mirror, concave reflecting mirror or convex shaped reflective mirrors.
From the foregoing, it will be observed that the utility model has the advantage that scientific structure is simple, design is reasonable, easy to manufacture, volume
It is small；In prior art basis, mirror front-reflection device is added in front of the projection lens of projector, by adjusting mirror front-reflection dress
The tilt angle for the reflecting mirror set achievees the purpose that change the radiation direction that projection lens projects come out, to easily control
The direction and position of projection imaging, to realize multi-faceted projection, can be imaged in the imaging of the back upper place of projector, surface,
Front upper place imaging.It is able to achieve people's viewing that is seated and is projected in image on metope, it also can be in the position for not having to change whole projector
In the case where, realize people's recumbency viewing projection image on the ceiling, it is very easy to use, keep product more humanized, has
There is preferable promotional value.
