Technical field

This patent belongs to advertisement media field, specifically relates to be arranged on the solution of the advertising device of middle-size and small-size vehicle roof.

Background technology

Advertisement media has spread all over each corner, but, the advertisement at middle-size and small-size vehicle roof is not the most developed.External earlier year has been released taxi and has been postponed the dual surface LED display card in vehicle body direction, facilitates the pedestrian on both sides to watch.Domestic also have production, but does not use, and there is the problems such as regulation, cost benefit, technology here.Low cost LED display card image quality is coarse, and brightness is weak；High cost LED display card puts into big, and cost recovery is difficult.And, LED display card must be powered on showing picture, when sunny, even if highlighted LED is also not easy it is clear that to night, LED dazzle also can allow people not see, and causes light pollution in city；Moreover, LED display card heating itself is serious, and the heat radiation of the roof steel plate that is exposed to the sun summer makes display card internal temperature can be up to more than 70 degree, and life and reliability is all tested.The mode of another kind of low cost be directly advertisement sticker on surface, the advertisement of this single static, allow people turn a blind eye to, effect of advertising are the poorest.Accordingly, it would be desirable to one can all realize on two sides switching ad content, the fine and smooth solution the most with low cost of image quality.

Roller display card is exactly main method, and the patent of this respect is a lot, can see application in a lot of occasions, but, the display card at vehicle-mounted top has many restrictions, such as, China Hongkong requires that hiring out roof display card is less than 20 kilograms, and height is less than 370 millimeters；So narrow space, the linear velocity that both sides will realize two spools is consistent, and can quick-replaceable spool secondary, Popular Aesthetics to be met.Because there being inner space, it is also contemplated that convenient and safe inspection.Requirements above to be taken into account is relatively difficult, therefore, the most at home and abroad, does not all have vehicle-mounted top two-sided roller multiple plate display card to occur.

Summary of the invention

The present invention provides the solution that a kind of vehicle-mounted top two-sided roller multiple plate is shown, is used for solving high cost, bandwagon effect, adaptation adverse circumstances and being easy to safety check.Including: with fixed mount, display card casing, driver element, spool and advertising cloth, lighting unit, the control unit etc. of car body.

Described and car body fixed mount plays the left and right fixing with car body, for traffic safety, needs reliable linking intensity, the associating fixed form that vacuum available sucker, strong adherence and screw are fixing, it is ensured that can resist high wind；Fixing display card casing on it.Display card casing has waterproof sealing and stop.

Described display card box house uses and longitudinally circulates Scroll Mode up and down, is made up of base plate and front and back bearings fixed mount and shell.For ease of safety inspection, cover top portion can transparent or rear bearing fixed mount be transparent material；Protective cover advertising display position, both sides is transparent；Anterior protective cover is printed on correlating markings, such as: taxi, taxi etc..Fixing two bearing fixed mounts on base plate, the spool being provided with advertising cloth between bearing fixed mount is secondary.Rear bearing fixed mount is additionally operable to install driver element.

Described driver element mainly comprises motor, transmission band or chain etc..nullWhen side advertising cloth is during another spool switching advertisement picture moved to by a spool，The diameter of two spools changes，When reversely switching，Also can change，Therefore，In transmission，The rotating speed of two spools is dynamically change，This species diversity transmission have to be realized，For proving the feasibility of the present invention，Spy is as an example: four spools，Every axle is all by an independent step motor drive，Each spool pair has upper and lower two spools，When the step motor drive of a spool，The motor of another correspondence is in disabled state，But still with the presence of location torque，Therefore advertising cloth is made to be in little tension，And driven shaft pulls，Switching advertisement page，All advertisement pages have switched，When needing reversely to switch，Originally the motor being in anergy starts to drive，And the motor originally driven is in disabled state；Two groups of spool byroad reasons are identical.

Described advertising cloth is the displaying medium that a long pair comprises some pictures；Spool each one at the two ends of advertising cloth, effect is as rolling type curtain, and advertising cloth is rolled image switching.Advertising cloth between two spools is in smooth slight tensioned state, and light source rearward makes picture become clear, it is simple to viewing.In practice, periodically or non-periodically change different ad content, need to shorten the artificial time changing advertising cloth as far as possible, thering is provided two kinds of methods: one, advertising cloth is sleazy substrate, at surface mount respective advertisement picture, during replacing, tear original, stick new；Its two, cartridge reel design is become quick-changing type, one group of spool pair comprise two spools and between advertising cloth, original one group is quickly pulled down, changes with new content one group, spool cost is the highest, moreover it is possible to recycling.The efficiency changed is greatly promoted.Embodiment 1 is described in detail.

The box house of described display card uses left and right traverse cycle Scroll Mode, the circulation spool stood by bottom skeleton and 2 and 4 sizing steering spindles form, 2 circulation spools have step motor drive respectively, and advertising cloth is pullled into U-shaped, it is achieved both sides can be watched.Changing spool pair also easy, as long as pulling out from above original, then plugging new the most permissible.

Described lighting unit is at display card box house, it is provided that sufficient backlight, in the case of can clearly watching by day, can illuminate, the most such as except taxi manned and unloaded etc. indicates.During insufficient light, illumination is necessary.In order to obtain uniform illumination, it is possible to use the softbox of frosted finish effect, it is also possible to allow softbox serve as advertising cloth by wall, the advertising cloth of exposition is stretched on softbox, more smooth, does not shakes, and backlight also can evenly be pressed close to.

Described control unit includes regulated power supply, panel, picture switching positioning inductor, temperature inductor, brightness impression device, stepper motor driver, GPS location and control program etc..Effect is to ensure that display card can be installed default function and be smoothed out.May be mounted in casing, it is also possible to be arranged on outside casing.

nullWork process of the present invention is: during longitudinal rolling mode，Side lower winding shaft step motor drive spool rotates，Overcome frictional force and the location torque of upper winding shaft motor，Pull advertising cloth downward，When position sensor senses advertising cloth breach，Stop operating，A width picture in advertising cloth just corresponding viewing window is described，Stop and set time span，Continue to pull downward on next width，The most repeatedly，During to a width topmost，Continue the shortest position of getting off，Induction apparatus senses again breach，It it is upper extreme point breach，Illustrate to have arrived at top，Start reversely，Upper winding shaft step motor drive spool rotates，Overcome frictional force and the location torque of lower winding shaft motor，Pull advertising cloth upwards，When position sensor senses advertising cloth breach，Stop operating，A width picture in advertising cloth just corresponding viewing window is described，Stop and set time span，Pull up on next width，The most repeatedly，Continue up the shortest position，Induction apparatus senses again breach，It it is lower extreme point breach，Illustrate to have arrived at bottom，The above action of repetitive cycling，Realize reciprocation cycle and show the purpose of several advertisements；Opposite side operating principle is the same, it is achieved the action of several advertisements of circularly exhibiting of both sides, allows both sides pedestrian can watch advertisement.

Laterally rolling mode is identical with longitudinal unilateral principle, and being simply transferred to both sides has display, because not occurring font to overturn, thus fairly simple, as long as one group of spool is secondary the most permissible.

The invention has the beneficial effects as follows: compact attractive in appearance, the bilateral LED screen being suitable for fictitious hosts high shows billboard；Because being printing product, image quality exquisiteness is natural, and visual sense organ exceedes the effective fruit of LED screen；Need not internal backlight by day during brightness height, save the energy；Night internal backlight by softbox uniform illumination, the most dazzling；Safety check can be carried out from outside naked eyes.Although changing advertising cloth to need cost and lost labor, but low income labourer employment can be increased, and absorb the production capacity of printing enterprise, be also beneficial to labourer's employment.

Detailed description of the invention

The present invention is further described with embodiment below in conjunction with the accompanying drawings.

Embodiment 1.

See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, longitudinal rolling mode is illustrated.Display card casing 300 is fixed on taxi 100 top by fixed mount 200, and display card casing 300 is postponed travel direction, and inside has 2 groups of spools secondary, it is simple to both sides, street pedestrian watches.

Display card casing 300 outward appearance is it can be seen that fore bearing fixed mount 301, rear bearing fixed mount 304, shell 302, base plate 313 and advertising cloth 303, and wherein fore bearing fixed mount 301 also serves as taxi 100 front panel, is not advertising display content because of it, therefore does not repeats.Rear bearing fixed mount 304 also serves as the fixing of spool drive stepping motor.In view of ventilation and heat, it is internal that outside air enters display card casing 300 by the hole bottom base plate 313, and hot-air blows out from the fixing fan 316 of rear bearing fixed mount 304.As the spool pair of left and right, therefore illustrating as a example by left side, upper left spool 305 and lower-left spool 310 that the left spool shown in Fig. 4 is secondary are contained in relevant position between the fore bearing fixed mount 301 shown in Fig. 3 and rear bearing fixed mount 304, and advertising cloth 303 is rolled to be tauted.

Lower-left spool motor 308 is fixed in motor fixed plate 309, and small synchronous pulley 312 is fixed on the axle of lower-left spool motor 308, is fixed on the most together on rear bearing fixed mount 304.Big synchronous pulley 311 is fixedly connected with lower-left spool 310, it is possible to drive lower-left spool 310 to rotate.Big synchronous pulley 311 is connected with Timing Belt with small synchronous pulley 312, tightens Timing Belt by the elongated hole of motor fixed plate.Because the speed driving spool is relatively low, in order to reduce the specification of motor, the number of teeth of big synchronous pulley 311 is 3 times of small synchronous pulley 312.Other three spools are as it is shown on figure 3, be the same.The motor moment that an opposing is rotated all the time in the case of not having power, referred to as location torque, moment when driving than energising is much smaller, around this principle, when lower-left spool motor 308 rotates counterclockwise, drive lower-left spool 310, overcome the location torque under frictional force and upper left spool motor 306 disabled state, advertising cloth 303 is pulled downward on, note the location torque relation because of gear ratio of now upper left spool motor 306, upper left spool 305 is amplified to 3 times, is more beneficial for tightening advertising cloth 303.

The sensing hole at advertising cloth edge as shown in Figure 4,8 middle position locations for each advertisement page, the groove type photoelectric switch 307 being fixed on rear bearing fixed mount 304 is relied on to sense, note that advertising cloth is translucent, hole is applicable, if transparent, need to stamp opaque mark in relevant position.When groove type photoelectric switch 307 senses that labelling, lower-left spool motor 308 stop operating, and advertising cloth 303 is positioned at next width location advertising.So repeatedly arriving position as shown in Figure 5, be a width advertisement topmost, continue to pull downward on, program is arranged on the short time i.e. senses next labelling, then illustrate to have arrived top, need recycled back.Now, upper left spool motor 306 drives, simultaneously lower-left spool motor 308 anergy, and advertising cloth 303 is pulled upward, and advertisement page location and lower end determine, the same with the principle pulled up.As the principle of left and right spool pair is also, circulate and so forth, it is achieved the advertisement page switching of both sides.

Quick-replaceable spool is secondary significant for reality application, and for the feasibility of proof scheme, the quick-changing type structure of spool as shown in Figure 6, this structure not determined that, outer the wear attachment structure similar with this is all derived from this.Connector 321, through big synchronous pulley 311 and rear bearing 319, tight fit connection, is then fixed on rear bearing fixed mount 304 by rear bearing 319, and fore bearing 320 is fixed on fore bearing fixed mount 301.During fast-assembling, lower-left spool 310 square hole generally facing to the center of rear bearing 319, connecting rod 322 is inserted from the square hole side of connector, import to, in the square hole of lower-left spool 310, be inserted into front end, the head round bar portion of connecting rod 322 is imported fore bearing 320 inner ring hole, it it is the cooperation in slightly gap herein, then at the screwed hole of connector 321, compress by key screw connecting rod 322, prevent it from scurrying out.When pulling down, it is only necessary to unclamp screw, extracting connecting rod 322, lower-left spool just is gone.Specifically be not meant to use square hole form, can from technique and cost consideration, with the pole of fluting can also, be connected as long as can facilitate with spool, the most permissible relative to preventing from rotating.

Backlight 318 two as shown in Figure 3, this is signal, is actually subjected to increase and decrease by effect.Light is radiated on two pieces of softbox 317, makes light the most scattered, then shines on advertising cloth 303, forms backlight, improves brightness, allows pedestrian see ad content clearly at relatively dark situation.

Embodiment 2.

See Fig. 7, horizontal rolling mode is illustrated.Owing to laterally rolling, the picture of both sides will not overturn, and structure is very simple, and left spool 601 is set with on left driving shaft 607, walks around 4 rotating shafts 602, and right spool 606 is enclosed within right driving axle 608, and motor 605 rotates, and pulls advertising cloth 603.Sequence of movement, positioning and arrive extreme position etc., as the principle of longitudinal rolling mode one side, simply the difference of rotating direction, repeats no more.
