The utility model compared with prior art has following beneficial effect: this MPV (Multi-Purpose Vehicle) road direction board reasonable in design, novelty, by gear train etc. the board turning assembly that is provided with the track indication is controlled, to show different track Warning Marks; Use this track direction board to carry out lane and can save lot of manpower and material resources, a board turning assembly that only needs to be provided with the track indication overturns as required, just can carry out the track indication, convenient quick, effect is obvious; And improved the service efficiency of road, alleviated the situation that vehicle blocks up.
Embodiment
Referring to Fig. 1, present embodiment is made up of box assembly I, the board turning assembly II that is provided with the track indication and gear train, transmission controlling mechanism and the position-limit mechanism that is arranged in the box assembly I.Box assembly I is made up of four casings 4, and the board turning assembly II that is provided with the track indication all is installed on each casing 4, in each casing 4 gear train, transmission controlling mechanism and position-limit mechanism is installed all.Be provided with track display device III in the front of box assembly I, this track display device III is positioned at the below of the board turning assembly II that is provided with the track indication.The board turning assembly II that is provided with the track indication has four in the present embodiment, they are positioned at the front of box assembly I, and be connected with gear train, gear train is connected with transmission controlling mechanism, and position-limit mechanism is installed in and is provided with on the position that the board turning assembly II of track indication is complementary.
Referring to Fig. 2~Fig. 4, in the present embodiment, the board turning assembly II that is provided with the track indication is made up of several board turnings 1, and gear train is a stepper motor 6, and transmission controlling mechanism comprises transmission shaft 2, chain 5 and transmission gear 8, and position-limit mechanism adopts travel switch 7.Wherein transmission shaft 2 links to each other with stepper motor 6 and chain 5 respectively, and board turning 1 is installed on the casing 4 and by axis 9 and is connected with transmission gear 8, and the cross sectional shape of this board turning 1 can be triangle.Be subjected to windage resistance when reducing to use, in the design of the back side of casing 4 by window shutter 3 structures.
Indicate three tracks altogether on the track display device III in the present embodiment, they can be consistent with the lane markings on the road surface.
During use (when needing to change the sign on the board turning assembly II that is provided with the track indication), press the gauge tap 11 on the control box, drive transmission gear 8 by stepper motor 6, drive chain 5 motions again, make each board turning 1 among the board turning assembly II that is provided with the track indication begin to rotate thus, when the trigonocephalia on the board turning 1 10 is run into travel switch 7, dump, stepper motor 6 quits work.At this moment, the board turning assembly II that is provided with the track indication goes up the required driveway travel directions that is that shows.
When needs change sign on the board turning assembly II that is provided with track indication once more and are driveway travel directions, can repeat above-mentioned action.
Referring to Fig. 4, this is a circuit theory synoptic diagram of the present utility model, when pressing switch 11, circuit turn-on, stepper motor 6 is started working, relay 12 is also switched on simultaneously, normally opened contact 13 closures of relay 12, the effect of normally opened contact 13 are when decontroling switch 11, the conducting situation of holding circuit, allow the 6 maintenance work of stepping motor, be provided with the board turning assembly II setting in motion (referring to Fig. 3) of track indication; In case when being provided with the board turning assembly II of track indication and being turned to assigned address, travel switch 7 is touched to be opened, circuit is cut off immediately, and stepper motor 6 quits work immediately.
In addition, need to prove that in structure of the present utility model, casing 4 and the board turning assembly II that is provided with the track indication are not limited to four, also can be three, five or other; Gear train is not limited to the chain structure; Transmission controlling mechanism also is not limited to stepper motor, and it also can be controlled or the like by single-chip microcomputer; Equally, position-limit mechanism also is not limited to travel switch, and it also can wait the purpose that reaches spacing by light activated element or electronic component.
Referring to Fig. 1, this is a Facad structure synoptic diagram of the present utility model, also is to use the utility model to carry out an embodiment of lane simultaneously.Under normal conditions, track direction board of the present utility model (promptly being provided with the board turning assembly II of track indication) content displayed is divided into track guiding arrow part II-1 and text prompt part II-2 two parts.Certainly, have only track guiding arrow part II-1 also to be fine.
In the present embodiment, when in a single day vehicle needs shunting,, the board turning assembly II that is provided with the track indication on four casings 4 is overturn as required by controller, make track guiding arrow part II-1 be turned into the required vehicle pass-through direction of shunting thus, promptly allow to keep straight on and turn left; Simultaneously, text prompt part II-2 can be turned into and the track guiding arrow corresponding prohibitory sign of part II-1 and word content, i.e. no right turn sign and no right turn literal.
Because track direction board own just must be installed in before the corresponding distance in crossing, so, the interim direction board that needs to place in advance will significantly reduce, and use is very simple, and effect is also very obvious.
Referring to Fig. 5, this is to use the utility model to carry out another embodiment of lane.In the present embodiment, vehicle is shunted if desired, can make by controller needs the board turning assembly II that is provided with the track demonstration of upset to overturn as required, makes track guiding arrow part II-1 be turned into the required vehicle pass-through direction of shunting thus, promptly allows left and right commentaries on classics of vehicle and craspedodrome; Simultaneously, text prompt part II-2 is turned into the literal of " please by track direction board direction running ".
In addition, the indicating mode in the utility model has more than and is confined in the above-mentioned specific embodiment, also can adopt other multiple indicating modes, and keep straight on and turn right as allowing, and no left turn, or the like.Certainly, also can implement lane change with line traffic control or remote control thereof.More than these conversion be conspicuous for the person of ordinary skill of the art, all should belong to protection domain of the present utility model.
