Specifically, the expression method of the outdoor large screen for the advertisement mainly comprises image advertisements, namely displaying the content of the advertisement by playing pictures and matching with proper word descriptions, and audio-visual advertisements, namely displaying the content of the advertisement by matching sound, images, music and rhythm, wherein the advertisement needs to leave a deep impression in the mind of a viewer while spreading the content to be displayed, the conventional outdoor large screen is basically formed by splicing a plurality of display screens 3 into a whole, and the advertisement, especially the audio-visual advertisement, is completely a dynamic display of video, although the display effect is better than that of a small screen, the dynamic display is limited in the video.
The invention has the beneficial effects that: according to the embodiment of the invention, the reciprocating mechanism is driven by the driving part 4 to move according to the requirement of advertisement content display, and the reciprocating mechanism drives the display screens 3 to displace in the vertical direction, so that the plurality of display screens 3 are dynamically changed, and the advertisement display visual effect is better.
Preferably, the outer frame 2 is of a cuboid structure, a plurality of movably spliced display screens 3 are arranged on the inner side of the outer frame, optionally, the display screens 3 are provided in two groups, a group of display screens is respectively arranged on two opposite sides of the cuboid structure, for example, a group of display screens is respectively arranged on the front side and the rear side, each group of display screens comprises a plurality of movably spliced display screens 3, and the two display screens 3 at corresponding positions on two sides of the outer frame 2 are connected to one reciprocating mechanism (see fig. 1); specifically, all set up display screen 3 in the both sides of frame 2, can install 3 devices of whole display screen in the centre of two-way road like this for the current stream of people all can watch the advertisement that is demonstrateed, thereby attracts more streams of people.
Preferably, the reciprocating mechanism comprises a rotating shaft 5 connected with the output shaft of the driving member 4 and a plurality of round blocks 6 arranged in parallel in the axial direction of the rotating shaft 5, the center of the cross section of the rotating shaft 5 and the center of the round blocks 6 are eccentrically arranged, a plurality of substrates 7 are arranged in parallel in the outer frame 2 along the axial direction of the rotating shaft 5, the substrates 7 are arranged in the outer frame 2 in a vertically sliding manner, the side surfaces of the round blocks 6 are in sliding contact with the lower surfaces of the substrates 7, the round blocks 6 are in one-to-one correspondence with the substrates 7, and the display screen 3 is connected with the substrates 7 (see fig. 3 and 4).
Specifically, when the driving member 4 works, the rotating shaft 5 connected with the driving member can be driven to rotate, the rotating shaft 5 rotates to drive the round block 6 to rotate circumferentially, the center of the cross section of the rotating shaft 5 and the center of the round block 6 are eccentrically arranged, so that when the round block 6 rotates circumferentially along with the rotating shaft 5, the rotating radius of the position, farthest from the rotating shaft 5, on the round block 6 is increased, the substrate 7 is in sliding contact with the side surface of the round block 6, if the round block 6 is taken as a reference object, the motion track of the substrate 7 is the side circumference of the round block 6, and the substrate 7 can only slide up and down in the outer frame 2, so that when the round block 6 moves circumferentially, the position, closest to the rotating shaft 5, of the side surface of the round block is alternatively in contact with the lower surface of the substrate 7 to the position, farthest from the side surface of the rotating shaft 5, the round block 6 can push up the substrate 7 along with the increase of the rotating radius, otherwise, the round block 6 can not push up the substrate 7 any more, and can move down under the action of gravity of the display screen 3 under the action of gravity of the display screen.
Further, a distance adjusting part 8 is arranged between the rotating shaft 5 and the round block 6, and the distance between the circle center of the cross section of the rotating shaft 5 and the circle center of the round block 6 is controlled by the distance adjusting part 8 (see fig. 3 and 4); specifically, the eccentric distance between the round block 6 and the rotating shaft 5 can be set in advance according to actual needs, some simple advertisements can be realized through the above mode, but along with the video content is more and more abundant, the above mode can seem to be lagged a bit, therefore, the distance adjusting piece 8 can be set according to actual needs, for example, when only some simple advertisements are displayed, the distance adjusting piece 8 can be set to the distance between the center line of the rotating screw rod control round block 6 and the rotating shaft 5, if the video content is abundant, the distance adjusting piece 8 can be set to the electric push rod, the electric push rod is electrically connected with the control center, then the stretching of the electric push rod is changed based on the video content, then the distance between the center line of the round block 6 and the rotating shaft 5 can be changed constantly, so the dynamic display effect can be better.
Further, a lifting mechanism 9 is disposed in the outer frame 2 (the lifting mechanism 9 only needs to be a structure capable of realizing a lifting function, which is the prior art and is not described herein in detail), and the driving member 4 is connected to the lifting mechanism 9 (see fig. 3 and 4); specifically, when the display screen 3 displays advertisements, the heights of some advertisements are higher, so that a look-up effect is given, a main body in a picture can give out a high, crowded, great or rising visual effect, the heights of some advertisements need to be lower, so that people can feel comfortable when seeing the advertisements, therefore, the use of the lifting mechanism 9 can drive the position adjusting unit to move upwards, all the display screens 3 are driven by the position adjusting unit to move upwards, all the display screens 3 achieve the purpose, secondly, when the weather is strong in the open air, the outer frame 2 blocks wind, the position of the outer frame 2 where the display screen 3 is arranged is not blocked by the display screen 3, and has no other structures, so that the wind force formed when the wind passes through the position is larger, because when the airflow flows from a wide area, an acceleration effect can be formed, the display screen 3 can segment the position where the display screen 2 flows through the wind, the ventilation area is further reduced, when the strong wind basically blows against the display screen 3, the influence of the display screen 3 is also influenced by the wind force, even the display screen 3 shakes, and the display screen 3 moves downwards when the display screen 3 moves downwards, the display screen 3 is damaged by the influence of the gravity, and the display screen 3 moves downwards, and the display screen 3 is larger.
Further, 3 backs of display screen are provided with connecting block 10, be provided with connecting rod 11 on the base plate 7, connecting block 10 with rotate through round pin axle 12 between the connecting rod 11 and connect and the two junction is equipped with first elastic component (first elastic component is the torsional spring), 3 upward shift stroke end point of display screen department be provided with wedge 13 on the frame 2, the low side of wedge 13 is close to base plate 7, 3 upper ends of display screen with wedge 13 corresponds (refer to fig. 3 and 5).
Specifically, the wind level is from 0 to 12, and in order to protect the display screen 3 and normally display the advertisement, an embodiment is provided, such as:
when the wind is in the level 0 to 4, the first elastic member can enable the connecting block 10 and the connecting rod 11 to be in the same horizontal line, namely, the display screen 3 is in a vertical state, and the advertisement can be normally displayed.
When the wind is in 5 to 8 levels, the reciprocating mechanism enables all the display screens 3 to be positioned on the same horizontal line, then the lifting mechanism 9 drives all the reciprocating mechanisms to move upwards integrally, the reciprocating mechanism drives the display screens 3 to move upwards to enable the upper ends of the display screens 3 to be in contact with the wedge-shaped surfaces 13, the upper ends of the display screens 3 continuously press the wedge-shaped surfaces 13 along with the driving of the display screens 3 to move upwards, the pressing force can form a pressing force, the pressing force decomposes a force vertical to the wedge-shaped surfaces 13 and a force along the inclined direction of the wedge-shaped surfaces 13 on the wedge-shaped surfaces 13, the wedge-shaped surfaces 13 are arranged on the outer frame 2, the outer frame 2 cannot be pushed, the display screens 3 are rotatably connected with the connecting rods 11 through the connecting blocks 10, and the upper ends of the display screens 3 can move along the inclined directions of the wedge-shaped surfaces 13, so the display screen 3 just can use round pin axle 12 to take place to deflect as the axle, the contained angle between display screen 3 and the connecting rod 11 increases thereupon, according to the size of wind-force, the distance that the display screen 3 shifts up can the elevating system 9 control, then its inclination just also can be controlled, and when wind blows to the display screen 3 of slope, can be guided by display screen 3, make the wind flow direction change, the power that wind gave display screen 3 promptly can be decomposed, a part is born by display screen 3, another part is along display screen 3 incline direction, so can realize the effect of uninstallation wind power, thereby play the purpose of protection display screen 3, the display screen 3 of part slope can continue to demonstrate the advertisement on frame 2, the display screen 3 of slope, can also reduce people's new line angle.
When wind is in a level of 9 to 12, the lifting mechanism 9 operates to drive the position adjusting unit to move downwards, all the display screens 3 move downwards by utilizing the self gravity and the gravity of the parts such as the substrate 7 and the like, and all the display screens 3 move downwards to the lower part of the outer frame 2 to protect the display screens 3.
Still further, the connecting block 10 is fixedly connected to the pin 12, the connecting rod 11 is rotatably connected to the pin 12, a limiting member is disposed at a connection position between the connecting block 10 and the connecting rod 11, and the limiting member includes a limiting groove 14 formed in the pin 12 and a limiting block 15 fixedly connected to the connecting rod 11 (see fig. 7 and 8); specifically, when wind is in a level of 0 to 4, the first elastic member can enable the connecting block 10 and the connecting rod 11 to be in the same horizontal line, that is, the display screen 3 is in a vertical state and can normally display advertisements, but the thrust generated by the wind to the display screen 3 needs to be balanced all the time by the elastic force of the first elastic member, and the display screen 3 also has gravity, if the elastic force of the first elastic member is not available, the display screen 3 can swing downwards around the pin shaft 12 due to the influence of the gravity of the display screen 3, so that the first elastic member always works when the wind is small, the service life of the first elastic member can be shortened.
In the above embodiment, the reason why the separation between the limiting groove 14 and the limiting block 15 needs to be with the help of external force is that the limiting block 15 can slide on the surface of the pin shaft 12 with the same radian all the time in the process of entering the limiting groove 14, the sliding process is free from resistance, otherwise, when the limiting block 15 is separated from the limiting groove 14, the edge of the limiting groove 14 needs to be overcome, the limiting block needs to be moved from a lower position to a higher position, therefore, the separation can be completed only by overcoming a certain resistance, the elastic deformation of the limiting block 15 can be generated, but the force required by the elastic deformation is generated, the wind power is in the level of 0 to 4, and the gravity of the display screen 3 is insufficient to overcome the force required by the elastic deformation of the limiting block 15.
When wind is in a level of 9 to 12, the advertisement is no longer convenient to display, and the display screens 3 need to be protected, in the embodiment, the lifting mechanism 9 drives the position adjusting units to move downwards, all the display screens 3 move downwards by utilizing the gravity of the display screens 3 and the gravity of the parts such as the base plate 7 and the like, all the display screens 3 move to the lowest part of the outer frame 2, but the display screens 3 are still in a vertical state and are still influenced by wind power, and if the display screens 3 can be in a horizontal state at the moment, the wind power borne by the display screens can be greatly reduced, and the problem is solved by arranging the guide grooves 17 in the embodiment of the invention.
Further, a vertical sliding groove 16 is formed in the back of the display screen 3, the connecting block 10 is arranged in the sliding groove 16 in a vertically sliding manner, a second elastic member is connected between the connecting block 10 and the lower end of the sliding groove 16, a guide groove 17 is formed in the outer frame 2 at the position of the terminal point of the downward movement stroke of the display screen 3, and the lower end of the display screen 3 corresponds to the guide groove 17 (see fig. 3 and 6); specifically, when the wind is in the 9 to 12 levels, the lifting mechanism 9 drives the position adjusting unit to move downwards, all the display screens 3 move downwards by utilizing the self gravity and the gravity of the parts such as the substrate 7, and the like, after the lower ends of the display screens 3 are contacted with the guide grooves 17, the lower ends of the display screens 3 always give a thrust perpendicular to the inner walls of the guide grooves 17 and a force along the track direction of the inner walls of the guide grooves 17 to the inner walls of the guide grooves 17, the guide grooves 17 are arranged on the outer frame 2, the outer frame 2 is difficult to be pushed, so that the lower ends of the display screens 3 can move along the track direction of the inner walls of the guide grooves 17, and in the moving process, the guide grooves 17 can generate opposite acting forces to the lower ends of the display screens 3 when guiding, so that the display screens 3 are pushed to deflect upwards by taking the pin shafts 12 as the shafts, in the process that the lifting mechanism 9 drives the reciprocating mechanism to move to the lowest position in the outer frame 2, when the deflection of the display screen 3 is hindered by the guide groove 17, the display screen 3 tends to be pushed to move upwards, and at the moment, the display screen 3 is in an inclined state, and the connecting block 10 can slide downwards in the sliding groove 16, so that the connecting block 10 can move downwards along with the reciprocating mechanism and extrude the first elastic piece, along with the downward movement of the connecting block 10, the rotating shaft position of the display screen 3 is lowered, and the display screen 3 is in an inclined state, so that the display screen 3 can continuously deflect along the inclined direction, when the reciprocating mechanism is lowered to the lowest point, the display screen 3 is also in a basically horizontal state, and when wind flows through the position of the display screen 3, the resistance of the display screen 3 to the wind can be greatly reduced, so that the display screen 3 is further protected.
Preferably, the groove wall of the guide groove 17 is composed of a first inclined surface 18, a second arc surface 19 and a third inclined surface 20, the second arc surface 19 is located at the lower end of the first inclined surface 18 and the second inclined surface, and the lower end of the display screen 3 sequentially comes into sliding contact with the first inclined surface 18, the second arc surface 19 and the third inclined surface 20 when entering the guide groove 17 (see fig. 3, 5 and 6); specifically, its lower extreme contacts with first inclined plane 18 earlier in the in-process that display screen 3 moved down, then move down along the incline direction of first inclined plane 18, make display screen 3 use round pin axle 12 to take place to deflect as the axle, when the in-process of display screen 3 lower extreme through second arc surface 19, second arc surface 19 can play the effect of turning to display screen 3, make display screen 3's deflection angle bigger, and after display screen 3 lower extreme reachd third inclined plane 20, display screen 3 also deflects gradually to the horizontality, so guide way 17 plays the guide effect to display screen 3, make it deflect to the horizontality from vertical state.
Preferably, the display screen 3 is in a stroke part between the end of the upward movement stroke and the end of the downward movement stroke, and the connecting block 10 is always abutted against the upper end of the sliding chute 16 (see fig. 3 and 5); specifically, utilize display screen 3 self gravity, make spout 16 upper end support with connecting block 10 all the time and lean on, can drive the in-process that display screen 3 reciprocated at reciprocating mechanism, the problem of rocking about can not appearing in display screen 3, be connected with the second elastic component with the upper end and the lower extreme of spout 16 respectively if the upper and lower surface of connecting block 10, then because the inertia of display screen 3 self, reciprocating mechanism drives the in-process that display screen 3 reciprocated, just can make display screen 3 appear rocking problem, thereby influence the dynamic bandwagon effect of advertisement, still can influence display screen 3 to go up its upper end and wedge 13 contact go on of emergence slope process, promptly display screen 3 upper end and wedge 13 contact back, can receive the reaction force that comes from wedge 13, thereby produce the resistance to display screen 3, make the demonstration unable slope that takes place, but take place the circumstances that moves down on connecting block 10, just so can's unable according to the wind-force size, the inclination of more accurate control display screen 3.
