Such design is: during second gear rotation, second gear drives the rotation with gear more at a slow speed, to protect Card could drive about one circle of first gear rotation after second gear rotates many circles, so that first gear is needed by one section Triangular form driving lever could be driven to cross corresponding limited block through first rotating shaft, scroll spring and driving cylinder after time.

The first ring set, connecting rod, the first centrifugal wheel, first are centrifuged setting for spring, centrifugal-block and the second shaft in the present invention Meter is: the first ring set drives the first centrifugal wheel to rotate through connecting rod, and the first centrifugation spring and centrifugal-block follow the first centrifugal wheel Rotation；When the first ring set rotates at a slow speed, the first centrifugal wheel can drive the rotation of the second shaft through centrifugal-block；When the rotation of the first ring set Rotary speed is gradually increased, and after reaching a certain critical value, and the first centrifugal wheel can not drive the rotation of the second shaft through centrifugal-block, at this time First centrifugal wheel still drives the first centrifugation spring and centrifugal-block to rotate.

The second centrifugation sliding slot, the second centrifugation spring and centrifugation plate need to meet in the present invention: in the rotation of the second centrifugal wheel In the process, when centrifugation plate is stretched out from the second centrifugation sliding slot under centrifugal force, centrifugation plate will not take off from the second centrifugation sliding slot always From.

For the second shaft, third gear, the second centrifugal wheel, centrifugation plate, the second centrifugation spring, connection strap, U-shaped board, the The design of two ring sets, telescopic rod, second gear, the first tapered friction pulley, friction pulley, the second tapered friction pulley and the 4th gear exists Third shaft is driven to rotate through third gear, the 4th gear in: the second shaft, third shaft drives the through the second tapered friction pulley One tapered friction wheel from rotation, the first tapered rubbed wheel of friction pulley drive flexible interior bar rotation, and interior bar of stretching is through outer cuff of stretching Dynamic second gear rotation.Second shaft drives the rotation of the second ring set through the second centrifugal wheel, centrifugation plate, connection strap and U-shaped board.Due to Flexible interior bar is mounted in the second ring set far from one end of flexible housing by bearing, then stretching interior under the action of bearing The rotation of bar and the rotation of the second ring set will not have an impact.For the second centrifugal wheel, when the second centrifugal wheel does not rotate, friction Take turns the rear tapered end phase frictional fit with the first tapered friction pulley；When the rotation of the second centrifugal wheel, centrifugation plate is under the action of the centrifugal force It being stretched out to outside the second centrifugal wheel, the second centrifugation spring is stretched, during centrifugation plate is stretched out to outside the second centrifugal wheel, centrifugation Plate drives flexible interior bar mobile to the direction of the second centrifugal wheel through connection strap, U-shaped board, the second ring set, and friction pulley follows in flexible Bar is mobile, and then the direction of friction pulley to the preceding tapered end of the first tapered friction pulley is mobile；When the second centrifugal wheel rotation speed by It is cumulative it is big after, the second ring set through flexible interior bar drawing friction wheel to the mobile distance of the second centrifugal wheel bigger, friction pulley and first Preceding tapered end of the position of tapered friction pulley phase frictional fit closer to the first tapered friction pulley.That is: first, at second turn When axis does not drive the second centrifugal wheel to rotate, the rear tapered end phase frictional fit of friction pulley and the first tapered friction pulley；Second, second Shaft drive the second centrifugal wheel rotation speed from zero be gradually increased rear when, inner cone extreme direction of the friction pulley to the first tapered friction pulley It is mobile；Third, when the second shaft drives the speed of the second centrifugal wheel rotation to reach maximum, friction pulley just tapered rubs with first Wipe the preceding tapered end phase frictional fit of wheel.

The design parallel with the axis of flexible interior bar with the bus of friction pulley phase CONTACT WITH FRICTION of first tapered friction pulley is protected It demonstrate,proves, when friction pulley is mobile to the inner cone extreme direction of the first tapered friction pulley, friction pulley always can be with the first tapered friction pulley Male cone (strobilus masculinus) generate frictional fit.Friction pulley to the inner cone extreme direction of the first tapered friction pulley it is mobile designed for: During the rotation speed of second shaft is gradually increased, after the transmitting of each structure, the rotation speed of the first tapered friction pulley Degree is also increasing, and friction pulley and the male cone (strobilus masculinus) diameter of the first tapered friction pulley phase frictional fit are smaller and smaller, to guarantee During the rotation speed of the second shaft and the first tapered friction pulley is gradually increased, the rotation speed of friction pulley is kept as far as possible It is constant, finally enable friction pulley to drive the rotation speed of first gear to remain unchanged as far as possible through telescopic rod and second gear.

For adjusting ring, by the design of throw-out collar, the first spring, guide block and limited block: since the first spring is in pressure always Contracting state, so guide block, under the action of the first spring and limited block, guide block can be located at the bosom of guide groove, to guarantee guide block It will not be detached from from guide groove, so that limited block will not be detached under the reset force of the first spring from limit sliding chutes.It adjusts Ring push it is mobile to limit Block direction by throw-out collar, thus can further adjust the first spring by decrement so that limit It is increasing that position block is pressed into the strength in limit sliding chutes.

First gear, first rotating shaft, scroll spring, driving cylinder, triangular form driving lever, limited block and one-way clutch in the present invention The design of ring: first gear drives driving cylinder to rotate through first rotating shaft, scroll spring, and triangular form driving lever follows driving cylinder rotation, It is clockwise for setting and driving the direction of rotation of cylinder at this time；Driving cylinder drives triangular form billboard to rotate clockwise；One-way clutch ring Designed for: allow drive cylinder rotate clockwise, forbid drive cylinder rotate counterclockwise, and then guarantee triangular form billboard It will not rotate counterclockwise.

The effect that inclined-plane on limited block is matched with triangular form driving lever: first, when first rotating shaft does not rotate, drive cylinder When not rotating, in the raw, triangular form driving lever is in contact scroll spring with the inclined-plane of a limited block；Second, when first When shaft rotates, first rotating shaft drives driving cylinder to rotate through scroll spring, at this time since the first spring is compressed, drives on cylinder Triangular form driving lever is difficult to for limited block being pressed into limit sliding chutes, then triangular form driving lever and driving cylinder will not rotate, whirlpool Coil spring is by compressed energy-storage；Third, when scroll spring is compressed to it is a certain amount of when, at this time scroll spring through drive cylinder be supplied to three The power of stirring of angle-style driving lever is entirely capable of being pressed into limited block in limit sliding chutes, and then first rotating shaft can be through scrollwork bullet Spring, driving cylinder and triangular form driving lever cross the limited block；4th, after triangular form driving lever crosses corresponding limited block, then Continuing under rotation and the reset of scroll spring for second shaft, drives cylinder and triangular form driving lever that can rotate to next limit rapidly The position of block, subsequent triangular form driving lever are in contact with the inclined-plane of the limited block cooperation again.

The increase adjustment of the first amount of spring compression can make limited block be pressed into limit sliding chutes in the present invention Strength it is bigger so that the compressed amount of scroll spring is also required to bigger, finally first rotating shaft is made to need the more time Energy storage is rotated, it is more next to reach the time that first rotating shaft successively crosses limited block through scroll spring, driving cylinder and triangular form driving lever Longer, driving cylinder drives the Frequency downshift of triangular form billboard rotation switching, to meet triangular form billboard under different situations The effect of publicity.

The design of three limited blocks along circumferential direction, so that driving cylinder is after triangular form driving lever crosses each limited block Rotating angle is 120 degree, so that driving cylinder drives the rotation angle of triangular form billboard to be set at 120 degree, meets three Angle-style billboard brings the purpose of three wide announcements of publicity triangular form billboard by rotary cutting.

Billboard in the present invention is mounted on the roof of taxi.When taxi not when driving, blade does not drive first Ring set rotation, first rotating shaft do not rotate, and in the raw, triangular form driving lever connects scroll spring with the inclined-plane of a limited block Touching, the advertising plane on the two sides of triangular form billboard publicizes the external world at this time.Second centrifugal wheel does not rotate, friction pulley and first The rear tapered end phase frictional fit of tapered friction pulley.

Setting: when taxi when driving, blade drives the first ring set to rotate clockwise after being blown by wind；When the row of taxi When sailing speed and reaching 30km/h, the first centrifugal wheel can not just drive the rotation of the second shaft through centrifugal-block.

When taxi at a slow speed when driving, blade drives the first ring set to rotate clockwise after being blown by wind, the first ring set is through even Extension bar drives the first centrifugal wheel to rotate clockwise, and the first centrifugation spring and centrifugal-block follow the first centrifugal wheel to rotate, and at this time first Centrifugal wheel can drive the second shaft to rotate clockwise through centrifugal-block.Second shaft through third gear, the 4th gear, third shaft, Second tapered friction pulley, the first tapered friction pulley, friction pulley and telescopic rod drive second gear to rotate counterclockwise.Second gear band Dynamic first gear rotates clockwise；First gear drives first rotating shaft to rotate clockwise, and first rotating shaft drives through scroll spring and drives Dynamic cylinder rotation drives the triangular form driving lever on cylinder to be difficult to for limited block to be pressed into limit at this time since the first spring is compressed In the sliding slot of position, then triangular form driving lever and driving cylinder will not rotate, scroll spring is by compressed energy-storage.When scroll spring is compressed to When a certain amount of, stir power of the scroll spring through driving cylinder to be supplied to triangular form driving lever is entirely capable of being pressed into limited block at this time Into limit sliding chutes, and then first rotating shaft can cross the limited block through scroll spring, driving cylinder and triangular form driving lever.In limited block After being pressed into limit sliding chutes, and after triangular form driving lever crosses the limited block, then under the effect of the first spring reset, The limited block is mobile to be resetted.After triangular form driving lever crosses corresponding limited block, then continuing rotation and whirlpool in the second shaft Under the reset of coil spring, drive cylinder and triangular form driving lever that can rotate to the position of next limited block rapidly, subsequent triangular form is dialled Bar is in contact with the inclined-plane of the limited block cooperation again, and driving the angle of cylinder rotation at this time is 120 degree.So driving cylinder drives three Angle-style billboard rotates 120 degree, and triangular form billboard drives fixed link rotation, and triangular form billboard rotary cutting brings publicity triangle The advertisement of the another side of type billboard.When triangular form billboard rotates switching next time, repeats scroll spring and be compressed to one Triangular form driving lever is made to cross the process of limited block after quantitative.

When the travel speed of taxi is gradually increased and when close to 30km/h, the first ring set drives through the first centrifugal wheel at this time The rotation speed of second shaft reaches maximum.Due to the friction pulley design mobile to the inner cone extreme direction of the first tapered friction pulley, So that the rotation speed of friction pulley is as far as possible during the rotation speed of the second shaft and the first tapered friction pulley is gradually increased It remains unchanged, enables friction pulley to drive the rotation speed of first gear to remain unchanged as far as possible through telescopic rod and second gear, most Whole first gear drives the speed of driving cylinder intermittence rotation to remain unchanged as far as possible through first rotating shaft and scroll spring, guarantees to hire out Vehicle be less than 30km/h travel speed when, triangular form billboard rotation switching speed remain unchanged as far as possible, improve three The effect of angle-style billboard publicity.

After the travel speed of taxi is more than 30km/h, the first ring set drives the first centrifugal wheel still up time through connecting rod Needle rotation, only the first centrifugal wheel can not drive the rotation of the second shaft through centrifugal-block, and such second shaft will not rotate any more, the Two shafts no longer input power, triangular form billboard will will not rotate any more switching.Such design advantage is: in taxi Travel speed is more than 30km/h, and pedestrian is not easy to see the advertising slogan of triangular form billboard, the rotation switching of triangular form billboard Function will there is no better effects, so triangular form billboard will stop after the travel speed of taxi is more than 30km/h Spin-ended turn of switching.In addition, the design that triangular form billboard stops rotating also avoids triangular form billboard in the traveling of taxi Speed is more than not stop the movement of rotation switching after 30km/h still, to reduce triangular form billboard because of long-time rotary cutting Structural wear caused by changing；It is equivalent to the service life of associated structure when extending the rotation switching of triangular form billboard.

After the travel speed of taxi is more than 30km/h, the second shaft no longer rotates, in the reset of the second centrifugation spring Under effect, centrifugation sheet reset to home position is centrifuged plate through connection strap, U-shaped board, the second ring set and flexible interior bar and drives friction pulley Movement resets to home position, that is, the position of friction pulley and the rear tapered end phase frictional fit of the first tapered friction pulley.

One-way clutch ring in the present invention can limit the rotation counterclockwise of triangular form billboard, and triangular form billboard Corresponding limited block can just be crossed after needing scroll spring to store enough energy by rotating clockwise；When occur external influence make it is suitable When hour hands rotary triangle type billboard, the switching that rotates clockwise of triangular form billboard needs sufficiently large energy, so generally External influence be insufficient to allow triangular form billboard to rotate clockwise switching, to substantially reduce triangular form billboard by outer A possibility that boundary can rotate freely switching after influencing.After triangular form billboard occur and rotating clockwise switching, in scroll spring Reset force under, driving cylinder can drive triangular form billboard that can quickly rotate 120 degree completely, and the reset response energy of scroll spring The error when rotation switching of triangular form billboard is made up, guarantees that triangular form billboard rotates every time and is cut to 120 degree.

Relative to traditional billboard technologies, the triangular form billboard in the present invention can the stopping when taxi is run at high speed Rotation switching, and switching is rotated to intermittence when taxi is run at a low speed, so that triangular form billboard be enable effectively to publicize Three wide announcements, considerably increase advertisement benefit.The friction pulley design mobile to the inner cone extreme direction of the first tapered friction pulley, can make Taxi is obtained in different low speed downward driving speed, the speed of the rotation switching of triangular form billboard remains unchanged as far as possible, more Improve the effect of triangular form billboard publicity.In addition, driver can be pushed by rotating adjustment ring by throw-out collar, to increase The decrement of first spring so that first rotating shaft through scroll spring, driving cylinder and triangular form driving lever successively cross limited block when Between it is increasingly longer, driving cylinder drives the Frequency downshift of triangular form billboard rotation switching, to meet triangular form under different situations The effect of publicity of billboard.The configuration of the present invention is simple has preferable using effect.

Specific embodiment: the billboard in the present invention is mounted on the roof of taxi.When taxi not when driving, leaf Piece 9 does not drive the first ring set 16 to rotate, and first rotating shaft 48 do not rotate, scroll spring 52 in the raw, triangular form driving lever 53 It is in contact with the inclined-plane 61 of a limited block 54, the advertising plane on the two sides of triangular form billboard 4 publicizes the external world at this time.The Two centrifugal wheels 21 do not rotate, the rear tapered end phase frictional fit of friction pulley 25 and the first tapered friction pulley 29.

Setting: when taxi when driving, blade 9 drives the first ring set 16 to rotate clockwise after being blown by wind；Work as taxi Travel speed when reaching 30km/h, the first centrifugal wheel 18 can not just drive the rotation of the second shaft 19 through centrifugal-block 33.

When taxi at a slow speed when driving, blade 9 drives the first ring set 16 to rotate clockwise after being blown by wind, the first ring set 16 The first centrifugal wheel 18 is driven to rotate clockwise through connecting rod 15, the first centrifugation spring 34 and centrifugal-block 33 follow the first centrifugal wheel 18 Rotation, the first centrifugal wheel 18 can drive the second shaft 19 to rotate clockwise through centrifugal-block 33 at this time.As shown in figure 14, the second shaft 19 through third gear 20, the 4th gear 32, third shaft 31, the second tapered friction pulley 30, the first tapered friction pulley 29, friction pulley 25 and telescopic rod 27 drive second gear 28 counterclockwise rotate.As shown in figure 5, second gear 28 drives first gear 47 clockwise Rotation；As shown in Figure 5,6, first gear 47 drives first rotating shaft 48 to rotate clockwise, and first rotating shaft 48 is through 52 band of scroll spring Dynamic driving cylinder 42 rotates, and at this time since the first spring 57 is compressed, the triangular form driving lever 53 on cylinder 42 is driven to be difficult to limited block 54 are pressed into limit sliding chutes 59, then triangular form driving lever 53 and driving cylinder 42 will not rotate, scroll spring 52 is compressed Energy storage.When scroll spring 52 is compressed to a certain amount of, scroll spring 52 is through driving cylinder 42 to be supplied to triangular form driving lever 53 at this time Power of stirring be entirely capable of being pressed into limited block 54 in limit sliding chutes 59, and then first rotating shaft 48 can be through scroll spring 52, cylinder 42 and triangular form driving lever 53 is driven to cross the limited block 54.After limited block 54 is pressed into limit sliding chutes 59, And after triangular form driving lever 53 crosses the limited block 54, then the limited block 54 is mobile to be resetted under 57 reset response of the first spring. After triangular form driving lever 53 crosses corresponding limited block 54, then second shaft 19 continue rotation and scroll spring 52 is answered Under position, drive cylinder 42 and triangular form driving lever 53 that can rotate to the position of next limited block 54, subsequent triangular form driving lever 53 rapidly Be in contact with the inclined-plane 61 of the limited block 54 cooperation again, and the angle for driving cylinder 42 to rotate at this time is 120 degree.So drive cylinder 42 Triangular form billboard 4 is driven to rotate 120 degree, triangular form billboard 4 drives fixed link 3 to rotate, the rotation switching of triangular form billboard 4 Come publicize triangular form billboard 4 another side advertisement.When triangular form billboard 4 rotates switching next time, scrollwork bullet is repeated Spring 52 be compressed to it is a certain amount of after make triangular form driving lever 53 cross limited block 54 process.

When the travel speed of taxi is gradually increased and when close to 30km/h, the first ring set 16 is through the first centrifugal wheel 18 at this time The rotation speed of the second shaft 19 is driven to reach maximum.Since friction pulley 25 is moved to the inner cone extreme direction of the first tapered friction pulley 29 Dynamic design, so that during the rotation speed of the second shaft 19 and the first tapered friction pulley 29 is gradually increased, friction pulley 25 rotation speed remains unchanged as far as possible, so that friction pulley 25 drives the rotation of first gear 47 through telescopic rod 27 and second gear 28 Rotary speed can remain unchanged as far as possible, and final first gear 47 drives driving 42 intermittence of cylinder through first rotating shaft 48 and scroll spring 52 The speed of rotation remains unchanged as far as possible, guarantee taxi be less than 30km/h travel speed when, the rotation of triangular form billboard 4 The speed of switching remains unchanged as far as possible, improves the effect of the publicity of triangular form billboard 4.

After the travel speed of taxi is more than 30km/h, the first ring set 16 through connecting rod 15 drive the first centrifugal wheel 18 according to It so rotates clockwise, only the first centrifugal wheel 18 can not drive the rotation of the second shaft 19, such second shaft through centrifugal-block 33 19 will not rotate any more, and the second shaft 19 no longer input power, triangular form billboard 4 will will not rotate any more switching.Such design Advantage is: it is more than 30km/h in the travel speed of taxi, pedestrian is not easy to see the advertising slogan of triangular form billboard 4, Triangular form billboard 4 rotation switching function will there is no better effects, so the travel speed in taxi is more than 30km/ After h, triangular form billboard 4 will stop rotating switching.In addition, the design that triangular form billboard 4 stops rotating also avoids triangle Type billboard 4 does not stop the movement of rotation switching still after the travel speed of taxi is more than 30km/h, to reduce triangle Type billboard 4 is because of structural wear caused by rotation switching for a long time；Be equivalent to extend triangular form billboard 4 rotation switching when The service life of associated structure.

After the travel speed of taxi is more than 30km/h, the second shaft 19 no longer rotates, in the second centrifugation spring 37 Under reset response, centrifugation plate 36 resets to home position, and centrifugation plate 36 is through connection strap 22, U-shaped board 38, the second ring set 23 and stretches Interior bar 24 drives the movement of friction pulley 25 to reset to home position, that is, the rear tapered end of friction pulley 25 and the first tapered friction pulley 29 The position of phase frictional fit.

One-way clutch ring 43 in the present invention can limit the rotation counterclockwise of triangular form billboard 4, and triangular form advertisement The rotating clockwise of board 4 can just cross corresponding limited block 54 after needing scroll spring 52 to store enough energy；It is extraneous when occurring When effect is so that rotate clockwise triangular form billboard 4, the switching that rotates clockwise of triangular form billboard 4 needs sufficiently large energy Amount, so general external influence is insufficient to allow triangular form billboard 4 to rotate clockwise switching, to substantially reduce triangular form A possibility that billboard 4 can rotate freely switching after being influenced by the external world.Switching is rotated clockwise when there is triangular form billboard 4 Afterwards, under the reset force of scroll spring 52, driving cylinder 42 can drive triangular form billboard 4 that can quickly rotate 120 degree completely, and whirlpool The reset response of coil spring 52 can overcome the disadvantages that the error when rotation switching of triangular form billboard 4, guarantee that triangular form billboard 4 revolves every time Turn to be cut to 120 degree.

In conclusion main beneficial effect of the invention is: the triangular form billboard 4 in the present invention can be in taxi high speed It stops rotating when driving switching, and rotates to intermittence switching when taxi is run at a low speed, to enable triangular form billboard 4 Three wide announcements are effectively publicized, advertisement benefit is considerably increased.Inner cone extreme direction of the friction pulley 25 to the first tapered friction pulley 29 Mobile design can make taxi in different low speed downward driving speed, and the speed of the rotation switching of triangular form billboard 4 is most Amount remains unchanged, and more improves the effect of the publicity of triangular form billboard 4.In addition, driver can by rotating adjustment ring 46 come It pushes by throw-out collar 58, to increase the decrement of the first spring 57, so that first rotating shaft 48 is through scroll spring 52, driving 42 and of cylinder The time that triangular form driving lever 53 successively crosses limited block 54 is increasingly longer, and driving cylinder 42 drives the rotation switching of triangular form billboard 4 Frequency downshift, to meet the effect of publicity of triangular form billboard 4 under different situations.The configuration of the present invention is simple has preferable Using effect.
