Abstract
The invention discloses a kind of loudspeaker van, including: 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 be opened；Travel mechanism, comprising: the guide rail that device is in compartment；Device rotation mounting seat on 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.The present invention can solve the problem that compartment iuuminting rate is bigger.
Description
Technical field
The present invention relates to publicize apparatus field, particularly to a kind of loudspeaker van.
Background technology
Existing exploitation car, its equal device in each face in compartment has rear projection screen, is carrying out advertisement a surname
During biography, although rear projection screen can play throw in advertisement purpose, but, rear projection screen can some printing opacity,
Light influences whether the input quality of projector after entering into compartment so that render to the advertisement on rear projection screen
Publicity thickens.
And, the projector on existing exploitation car is generally the projector of bigger power consumption, so makes
To install electromotor onboard, not only power consumption consumes big, increases cost, and the temperature in compartment is the highest,
Temperature is high produces certain impact to projector, accelerates the aging of projector parts.
Summary of the invention
The present invention is in order to after overcoming the rear projection screen printing opacity in each face in compartment in above-mentioned prior art, impact is thrown
The technological deficiency of quality thrown in by shadow instrument, has invented a kind of loudspeaker van.
For solving above-mentioned technical problem, the invention provides below scheme:
A kind of loudspeaker van, including: van-type car body, its railroad car lateral wall offers some loading frameworks,
On it, device has rear projection screen, in compartment wall corresponding inside it device have described rear projection screen can be blocked or
The photomask opened；Travel mechanism, comprising: the guide rail that device is in compartment；Device is at described guide rail
On rotation mounting seat；And LED projector, it is installed in described rotation mounting seat, and leads to
Crossing rotation 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, on it
Being provided with the support bar that can rotate, its end is connected with the drive shaft of one first motor, and this support
It is connected with described photomask one end on bar.
In technique scheme, described rotation mounting seat includes the track base being connected with slide；The end
The second motor being connected is fixed in portion with described track base；Its drive shaft is connected with described LED projector, with
Described LED projector is driven to rotate.
In technique scheme, also including a controller, it controls described first motor or/and the second motor
Rotate.
Compared with prior art, there is advantages that
1, the loudspeaker van in the present invention, utilizes the LED projector that can rotate and can will carry on the back
Throw the photomask that screen blocks or opens, 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 are by corresponding screening
Light film carries out light and blocks so that light can not enter in compartment, so that LED projector is at
Good input state；
2, by LED low-power consumption projector, it is compartment internal heat generation amount is little and power consumption is low, not only
Cost can be reduced, and energy consume can be reduced.
Accompanying drawing explanation
Fig. 1 is advertising car owner's TV structure schematic diagram of the present invention；
Fig. 2 is loudspeaker van side portion structure schematic diagram of the present invention；
In conjunction with accompanying drawing labelling the following drawings labelling thereon:
1-van-type car body, 2-rear projection screen, 3-LED projector, 4-the second motor, 5-track base, 6-guide rail,
7-support bar, 8-bearing, 9-photomask, 10-the first motor, 11-loads framework, 12-controller.
Detailed description of the invention
Below in conjunction with the accompanying drawings, a specific embodiment of the present invention is described in detail, but it should reason
Solve protection scope of the present invention not limited by detailed description of the invention.
It is to be appreciated that mentioned in the implementation below of the present invention " on ", D score, " left ",
" right ", " front " and " reverse side ", all on the basis of the direction shown in each figure, these are used for the side of restriction
To word be intended merely to facilitate explanation, do not represent the restriction of technical scheme concrete to the present invention.
As it is shown in figure 1, including according to the specific embodiment of the invention: 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 framework 11, on it, device has rear projection screen 2, and compartment wall device for upper end corresponding inside rear projection screen 2 has
Two bearings 8, are provided with the support bar 7 that can rotate, its end and one first electricity on two bearings 8
The drive shaft of machine 10 connects, and is connected with photomask 9 one end on this support bar 7, when the first motor 10
When driving support bar 7 to drive photomask 9 to move down, rear projection screen 2 can be completely covered by by photomask 9；
When the first motor 10 drives support bar 7 to drive photomask 9 up to move, photomask 9 is by rear projection screen 2
Open；Travel mechanism includes: device guide rail 6 in compartment；The end, is installed in device rotation on guide rail 6
Seat, it includes the track base 5 being slidably connected with guide rail 6；Bottom second electricity that be connected fixing with track base 5
Machine 4；LED projector 3 is connected with the drive shaft of the second motor 4, to drive LED projector 3 to rotate；
By rotating mounting seat, this LED projector 3 can project on any one piece of rear projection screen 2.
Embodiment of the present invention operation principle is: when LED projector 3 is thrown on any one piece of rear projection screen 2
Time, the corresponding photomask 9 of this rear projection screen 2 opens, and the corresponding photomask 9 of other rear projection screens 2 is equal
For occlusion state, if LED projector 3 changes rear projection screen 2 when throwing in, the rear projection screen before thrown in
2 is occlusion state, and the rear projection screen 2 again thrown in is open mode, so makes the light transmittance in compartment low,
Can be that LED projector 3 provides and most preferably throws in environment.
For more convenient operation, can increase by a controller 12, it controls the first motor 10 or/and the second motor 4
Rotate, it is not necessary to manually closely regulate and control, time-consuming.
The present invention passes through LED low-power consumption projector, and it is compartment internal heat generation amount is little and power consumption is low, no
Only can reduce cost, and energy consume can be reduced.
Last it is noted that above example only in order to the present invention is described and and the unrestricted present invention retouched
The technical scheme stated；Therefore, although the present invention is carried out by this specification with reference to each above-mentioned embodiment
Detailed description, but, it will be understood by those within the art that, still can be to the present invention
Modify or equivalent；And all without departing from the technical scheme of the spirit and scope of the present invention and change
Entering, it all should be contained in scope of the presently claimed invention.
