Description

A kind of dynamic menu simulator

A kind of dynamic menu simulator particularly relates to a kind of device that utilizes Moire fringe emulation dynamic menu.

Existing same device, China Patent No. 91203827.6 disclosed technology for example, comprise moving grating drive unit, the grating picture, housing etc., moving grating abuts against with the grating picture and translation mutually, forms dynamic effect, be motion or static observer can see dynamic menu.Because drive unit is arranged, the complicated reliability of fixing structure is low.

The utility model has designed a kind of animating means of not drive unit, and its purpose is to provide a kind of observer who has only motion just can see the animation simulation device of animation effect.

A kind of animation simulation device, comprise transmission grating, grating picture and supporting mass thereof, web member etc. is installed, have one between transmission grating and the grating picture apart from p (p＞3d), the pitch D of benchmark grating is transmission grating pitch d (1+p/L) times, and the projection of transmission grating on the grating picture is identical with the direction of benchmark grating.Under the irradiation of natural light or other light source, near the observer design point, along be not parallel to transmission grating direction when moving, can see dynamic image.For static observer, then see still image.

So-called benchmark grating that is: overlaps on the grating picture with correct angle when a grating, has produced desired Moire fringe, and it is D that this grating just is benchmark grating, its pitch.D also can be variable when pitch (non-etc.).

At enlargement factor (among the 1+p/L), p is the equispaced between transmission grating and the grating picture.When the two is parallel, be two interplanar distances.P generally determines by the angle that requires speed and transmission grating and observer's direction of motion of viewing distance, observer's translational speed, transmission grating, p can be from several millimeters to several meters.L is the distance of observer apart from transmission grating (or grating picture).Observer on this distance can see that error is very little or is zero Moire fringe.L can be taken as observer's mean distance, or the range of observation mid point is apart from the distance of picture.For example be put in the animating means in roadside, L can be taken as the walkway mid point apart from distance of animating means etc.Generally get than the littler numerical value of range of observation mid point distance.Enlargement factor is generally in the 1.01-1.10 scope.Optimal values is 1.02-1.06.

After having adopted above-mentioned design, the observer is equivalent to will transmission grating amplify (1+p/L) and will overlap on the grating picture after doubly, and just in time the reference light grid bearing with the grating picture is identical, pitch is identical, thereby forms accurately or Moire pattern more accurately.When the observer travels forward, be equivalent to transmission grating and move backward, thereby see dynamic menu.And when observer's head is static, picture still then, thus all suitable effect of sound formed.

In above-mentioned design, transmission grating is generally used pitch gratings such as parallel.It can be the transparent film grating, or the transparent membrane of band gum, also can be the grating that forms of various lines (as plastic cord, metal wire, linen-cotton line etc.) tensioning (transparency height), also can use wire netting, plastic wire, as multiple industrial net.The grid line angle is greater than 40 °.Wide with the net simulation context, windage is little.Also available radiation grating when transmission grating and grating picture are not parallel or when being the conical surface.The grid line direction of transmission grating is by observer's direction of motion, relative position, and movement velocitys etc. are determined.For example place the trackside pedestrian to watch, grid line above stair, then is level perpendicular to ground.

Viewing effect in order to improve a little less than night or the surround lighting can design light source before, during and after transmission grating and grating picture.Shot-light can be used in the front, and the back can be with spot etc.

The supporting member of grating picture can be glass, biochip, rigid frame or iron plate etc., also can be three-picture or many pictures turnover panel.Leaf through plate (or lamp box), fan-shaped dead axle page turning advertisement plate (180 ° of each fan-shaped each rotations) of triangular prism panel turnover device, roll type multiaspect for example.Adopt turnover device supporting grating picture can increase the advertisement capacity.Picture is outer can be equipped with shot-light.

Transmission grating and grating picture are generally the plane, also can make curved surface.As the conical surface, cylinder etc.Preferably plane or cylinder.The face of cylinder for example, triangular cylinder, quadrangular face etc.One week of cylinder is provided with several pictures, watches for all directions, is integrated with the buildings column, and is then very attractive in appearance.Can establish fluorescent tube in the cylinder.

In some cases, also can be only transmission grating be set in the moving place of needs, for example show window design etc., so then simpler.

Should be noted that not all sporter can see dynamic pattern.When having only observer's velocity reversal, just can see dynamic pattern not with the moving grid line parallel.

The utility model is used visual projection's principle, makes after mathematical analysis and repetition test.The designer finds for two gratings separated by a distance, when from one side through out-of-date, can see dynamic fringe.Therefore, for the observer of a motion, can omit the grating drive unit.But, when viewing distance not simultaneously, graphic change is very big.Can't obtain a definite image.The grating drive unit has been cast out in this design, has solved the problem of picture distortion again.It finds approach practical on a kind of engineering, and a kind of solution that vision requires that satisfies is provided.Promptly selected design point makes near its range of observation design point, sees accurately or is bordering on and move (quiet) attitude pattern accurately.

Therefore, the utility model is simple in structure because of movement-less part has, reliable operation, cheap advantage; The onlooker is moving to draw then that moving, onlooker is quiet then to draw quietly because of having only, so it is all suitable also to have sound, makes us the effect of stopping, gazing at.

The utility model can be in following applications, the passage both sides of station terminal, the both sides in the place ahead of stair, staircase or both sides, table of the shop, show window or walkway, street or front upper place, the two sides of Hou Cheting, automobile, the both sides of (at a high speed) highway etc.Can be used for the motion of the emulation vehicles, household electrical appliance operations, fluid flow the running of industrial products, the effect principle of medicine, technological process etc.Also can simulate the multiclass dynamic pattern, also can do dynamically to handle literal.Image is lively, and is in bright gay color, makes us stopping, and effective, the utility model also can be used for the handicraft field.
