Abstract

The utility model relates to a projector, in particular to a projector capable of projecting motion background. The projector is characterized in that a motion background component is assembled inside a casing, the motion background component is a first corrugated glass sheet driven to rotate by a motor, concave and convex grains are formed on the first corrugated glass sheet, and a projection light can generate refraction through the concave and convex grains. Positions of the concave and convex grains can be changed continuously when the first corrugated glass is driven to rotate by the motor, and then light changes dynamically and projection background projected by the projector has dynamic visual effect. Therefore, images projected by the projector are more vivid and variable.

Known projector is the interior lantern slide of this slide plateform of light-illuminating that utilizes this projecting lamp; amplify via convex lens at last and be projeced into the outside video picture of projector; being usually used in teaching, work briefing or works shows ... etc. occasion; its necessity and convenience are arranged in fact; only known projector is a machine of showing static images; regular meeting makes the beholder produce dullness, uninteresting sensation during the image that projects; reduce beholder's concentrated force, so cause wholwe-hearted on class or job morale low ... etc. problem.

Summary of the invention

The technical problems to be solved in the utility model is: the projection image of known projection machine is for static, easily makes the beholder produce dullness, uninteresting sensation, and causes the situation that can't concentrate on.

Technical solution of the present utility model is: a kind of projector is provided, it comprises a casing, convex lens, a slide plateform and a projecting lamp, these convex lens are located at casing one side, this slide plateform is located at this convex lens one side of casing inner near, this projecting lamp is located at the side of casing inside away from these convex lens, and the light of this projecting lamp can see through this slide plateform and convex lens in regular turn and project the casing outside, it is characterized in that:

One dynamic background assembly, it comprises one first motor, and one first corrugated glass, this first motor is located at casing inside, this first corrugated glass is located between projecting lamp and the slide plateform, and this first corrugated glass surface forms concave convex texture, and this first corrugated glass is fixedly arranged on the rotating shaft of this first motor, and this first corrugated glass can be subjected to first motor driven and rotates.

Aforesaid projector, this dynamic background assembly still comprises one second motor and one second corrugated glass, this second motor is located at casing inside, this second corrugated glass is located between slide plateform and projecting lamp, and this second corrugated glass surface forms concave convex texture, this second corrugated glass and the first corrugated glass crossover are provided with, and this second corrugated glass is fixedly arranged on the rotating shaft of second motor, and this second corrugated glass can be subjected to second motor driven and rotates.

Aforesaid projector, this dynamic background assembly still comprises a motor fixing base, and this motor fixing base is fixedly arranged on the casing inside bottom, and this first motor is fixedly arranged on this motor fixing base.

Aforesaid projector, this dynamic background assembly still comprises a motor fixing base, and this motor fixing base is fixedly arranged on the casing inside bottom, and this first motor and second motor are fixedly arranged on this motor fixing base.

The utility model has the advantages that: by establishing first corrugated glass that has concave convex texture to this surface, make light produce refraction by this first corrugated glass, and by this first corrugated glass rotation of this first motor driven, the position of concave convex texture is constantly changed, and then make light produce dynamic the variation, and just produce dynamic background effect via the dosing slide image that this light projects, make static originally projection image become lively, in addition, by establishing second corrugated glass that is provided with to this and the first corrugated glass crossover, and this second motor, it is more various to make that light changes, the effect of dynamic background also is rich in variability more.

Embodiment

To shown in Figure 2, disclose a kind of specific embodiment of projector provided by the utility model as Fig. 1, it comprises a casing 10, convex lens 11, a projecting lamp 12, a slide plateform 13 and a dynamic background assembly 2.

These convex lens 11 are located at casing 10 1 sides, and this slide plateform 13 is located at casing 10 inner near convex lens 11 1 sides, and this projecting lamp 12 is located at the side of casing 10 inside away from convex lens 11, and this slide plateform 13 is located between these convex lens 11 and the projecting lamp 12; This dynamic background assembly 2 comprises one first motor 21 and one first corrugated glass 22, this first motor 21 is located at casing 10 inside, this first corrugated glass 22 is located between this slide plateform 13 and the projecting lamp 12, this first corrugated glass 22 can be disc, and surperficial formation rule or irregular concave convex texture, the center of circle of this first corrugated glass 22 is fixedly arranged on the rotating shaft of this first motor 21, and can be subjected to the driving of this first motor 21 and rotate, this dynamic background assembly 2 can further comprise a motor fixing base 23, this motor fixing base 23 is located at casing 10 inside bottom surface, and this first motor 21 is fixedly arranged on this motor fixing base 23.

See also Fig. 3 to Fig. 5, it is the another kind of specific embodiment that discloses projector provided by the utility model, wherein, this dynamic background assembly 2 further comprises one second motor 24 and one second corrugated glass 25, this second motor 24 and first motor 21 are fixedly arranged on the two ends of this motor fixing base 23 respectively, this second corrugated glass 25 is located between this slide plateform 13 and the projecting lamp 12, this second corrugated glass 25 and the 22 crossover settings of first corrugated glass, and the surface of this second corrugated glass 25 has rule or irregular concave convex texture, this second corrugated glass 25 is fixedly arranged on the rotating shaft of this second motor 24, and driven by second motor 24 and rotate.

As shown in Figure 6, the utility model projector is when using, driving by this first motor 21 and second motor 24, drive this first

corrugated glass

22 and 25 rotations of second corrugated glass, the light of this projecting lamp 12 sees through first corrugated glass 22 in regular turn, second corrugated glass 25, lantern slide 3 in the slide plateform 13, amplification via convex lens 11 at last is projected to outside the development, because the surface of this first corrugated glass 22 and second corrugated glass 25 respectively has concave convex texture, make light produce refraction by concave convex texture, and see through the driven in rotation of motor, the position of this concave convex texture continues to change, make light present dynamic change by first corrugated glass 22 and second corrugated glass 25, therefore the background that is projected to external image also produces dynamic visual effect, makes projection image lively and active; In addition, increasing second corrugated glass 25 and second motor 24 that are provided with, is more changeable for the refraction that makes light source, makes projection image have variability more.
