Description
Technical field
The utility model relates to publicity apparatus field, particularly a kind of loudspeaker van.
Background technology
Existing exploitation car, it has rear projection screen at the equal device in each face in compartment, when carrying out advertising, although rear projection screen can play the object of throwing in advertisement, but, rear projection screen still can some printing opacity, can have influence on the input quality of projector, the advertising rendered on rear projection screen is thickened after light enters into compartment.
And the projector on existing exploitation car is generally the projector of larger power consumption, make so onboard generator to be installed, not only power consumption consumption is large, increases cost, and temperature in compartment is also high, temperature is high produces certain impact to projector, accelerates the aging of projector parts.
Utility model content
The utility model affects the technological deficiency that quality thrown in by projector after the rear projection screen printing opacity in order to overcome each face in compartment in above-mentioned prior art, invented a kind of loudspeaker van.
For solving the problems of the technologies described above, the utility model provides following scheme:
A kind of loudspeaker van, comprising: van-type car body, its railroad car lateral wall offers some loading frameworks, and on it, device has rear projection screen, and in compartment wall corresponding inside it, device has the photomask that described rear projection screen can be blocked or opens; Travel mechanism, it comprises: the guide rail of device in compartment; The rotation mounting seat of device on described guide rail; And LED projector, it is installed in described rotation mounting seat, and by rotating mounting seat, this LED projector can project on any one piece of rear projection screen.
In technique scheme, compartment wall device for upper end corresponding inside described rear projection screen has bearing, and it is provided with the support bar that can rotate, its end is connected with the driving shaft of one first motor, and this support bar is connected with described photomask one end.
In technique scheme, described rotation mounting seat comprises the track base be connected with slide; The second motor that bottom is fixedly connected with described track base; Its driving shaft is connected with described LED projector, rotates to drive described LED projector.
In technique scheme, also comprise a controller, it controls described first motor or/and the second motor rotates.
Compared with prior art, the utility model has following beneficial effect:
1, the loudspeaker van in the utility model, the LED projector that utilization can rotate and the photomask that rear projection screen can be blocked or open, LED projector can not only be made to project on any one piece of rear projection screen, and, when LED projector renders to any one piece of rear projection screen, other rear projection screens carry out light by corresponding photomask and block, and light can not be entered in compartment, so that LED projector can be in best commit condition;
2, by LED low-power consumption projector, it, compartment internal heat generation amount is little and power consumption is low, not only can reduce costs, and can reduce energy consume.
Accompanying drawing explanation
Fig. 1 is the utility model advertising car owner TV structure schematic diagram;
Fig. 2 is the utility model loudspeaker van side portion structure schematic diagram;
Mark the following drawings mark thereon by reference to the accompanying drawings:
1-van-type car body, 2-rear projection screen, 3-LED projector, 4-second motor, 5-track base, 6-guide rail, 7-support bar, 8-bearing, 9-photomask, 10-first motor, 11-loads framework, 12-controller.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
It will be appreciated that, mentioned in following embodiment of the present utility model " on ", D score, "left", "right", " front " and " reverse side " all with the direction shown in each figure for benchmark, these words being used for limiting direction are only used to be convenient to illustrate, do not represent the restriction to the concrete technical scheme of the utility model.
As shown in Figure 1, according to comprising of the utility model embodiment: van-type car body 1, rear projection screen 2, photomask 9, travel mechanism and LED projector 3; The railroad car lateral wall of van-type car body 1 offers some loading frameworks 11, on it, device has rear projection screen 2, compartment wall device for upper end corresponding inside rear projection screen 2 has two bearings 8, two bearings 8 are provided with the support bar 7 that can rotate, its end is connected with the driving shaft of one first motor 10, and this support bar 7 is connected with photomask 9 one end, when the first motor 10 drives support bar 7 to drive photomask 9 to move down, rear projection screen 2 can hide by photomask 9 completely; When the first motor 10 drives support bar 7 to drive photomask 9 up to move, rear projection screen 2 is opened by photomask 9; Travel mechanism comprises: the guide rail 6 of device in compartment; The rotation mounting seat of device on guide rail 6, it comprises the track base 5 be slidably connected with guide rail 6; The second motor 4 that bottom is fixedly connected with track base 5; LED projector 3 is connected with the driving shaft of the second motor 4, rotates with driving LED projector 3; By rotating mounting seat, this LED projector 3 can project on any one piece of rear projection screen 2.
The utility model embodiment principle of work is: when LED projector 3 is thrown on any one piece of rear projection screen 2, the corresponding photomask 9 of this rear projection screen 2 is opened, the corresponding photomask 9 of other rear projection screens 2 is occlusion state, if LED projector 3 changes rear projection screen 2 when throwing in, the rear projection screen 2 before thrown in is occlusion state, again the rear projection screen 2 thrown in is open mode, makes the transmittance in compartment low like this, can throw in environment for LED projector 3 provides best.
For more convenient operation, can increase by a controller 12, it controls the first motor 10 or/and the second motor 4 rotates, and manually closely need not regulate and control, save time.
The utility model is by LED low-power consumption projector, and it, compartment internal heat generation amount is little and power consumption is low, not only can reduce costs, and can reduce energy consume.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model; Therefore, although this instructions has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
