The blades penetrate through the air inlet square groove, the blades at the upper end of the first ring sleeve can be blown by external wind, the blades at the lower end of the first ring sleeve cannot be blown by the external wind under the shielding of the protective shell, and therefore the blades on the first ring sleeve can be smoothly blown by the external wind to rotate, and the blades drive the first ring sleeve to rotate.

As a further improvement of the present technology, the triangular billboard is provided with a lighting system. The design is convenient for the taxi to pass through the lighting system at night, so that the pedestrian can still see the advertising words on the triangular billboard.

As a further improvement of the present technology, the first centrifugal spring is a compression spring; the first centrifugal spring is always in a compressed state. The design is that: firstly, when the first centrifugal wheel does not rotate, the centrifugal block tightly presses the second rotating shaft under the action of the first centrifugal spring; secondly, when the first centrifugal wheel rotates slowly, the extrusion force of the centrifugal block on the second rotating shaft can still ensure that the centrifugal block can drive the second rotating shaft to rotate after the pressure of the first centrifugal spring is offset by the centrifugal force generated by the centrifugal block; thirdly, when the first centrifugal wheel rotates rapidly, after the pressure of the first centrifugal spring is offset by the centrifugal force generated by the centrifugal block, the extrusion force of the centrifugal block on the second rotating shaft is insufficient to ensure that the centrifugal block can drive the second rotating shaft to rotate, and further the rotation of the first centrifugal wheel cannot drive the second rotating shaft to rotate through the centrifugal block.

As a further improvement of the technology, the inner circular surface of the pushed ring is a smooth surface; the surface of the pushed ring, which is contacted with the adjusting ring, is coated with lubricating oil. Because the internal thread on the adjustable ring is in thread fit with the external thread on the annular groove, when the adjustable ring is rotationally adjusted by a user, the adjustable ring moves towards the direction of the pushed ring along the axis of the fixed ring sleeve under the action of thread fit, and then the adjustable ring pushes the pushed ring to move towards the direction of the limiting block, so that the first spring is continuously compressed. The surface of the pushed ring, which is in contact with the adjusting ring, is coated with lubricating oil, so that when the adjusting ring pushes the pushed ring in a rotating manner, the adjusting ring cannot drive the pushed ring to rotate, and the first spring is guaranteed to be smoothly compressed. The inner round surface of the pushed ring is smooth so as to ensure that the pushed ring can be pushed smoothly.

As a further improvement of the present technology, the first spring is a compression spring, and the first spring is always in a compressed state.

As a further improvement of the technology, the diameter of the first gear is 15-18 times of that of the second gear. The design is that: in the process of rotation of the second gear, the second gear drives the first gear to rotate at a slower speed, so that the first gear can be driven to rotate for about one circle after the second gear rotates for many circles, and the first gear can drive the triangular shifting lever to cross the corresponding limiting block through the first rotating shaft, the volute spring and the driving cylinder after a period of time.

The design of a first ring sleeve, a connecting rod, a first centrifugal wheel, a first centrifugal spring, a centrifugal block, a second gear and a second rotating shaft is as follows: the first ring sleeve drives the first centrifugal wheel to rotate through the connecting rod, and the first centrifugal spring and the centrifugal block rotate along with the first centrifugal wheel; when the first ring sleeve rotates slowly, the first centrifugal wheel can drive the second rotating shaft to rotate through the centrifugal block, and the second rotating shaft drives the second gear to rotate; when the rotation speed of the first ring sleeve is gradually increased and reaches a certain critical value, the first centrifugal wheel cannot drive the second rotating shaft to rotate through the centrifugal block, and at the moment, the first centrifugal wheel still drives the first centrifugal spring and the centrifugal block to rotate.

The design of the adjusting ring, the pushed ring, the first spring, the guide block and the limiting block is as follows: because first spring is in compression state all the time, so the guide block can be located the deepest of guide slot under the effect of first spring and stopper to guarantee that the guide block can not break away from the guide slot, and then make the stopper can not break away from spacing spout under the power that resets of first spring. The adjustable ring promotes to be pushed away the ring and removes to the stopper direction, just so can further adjust the volume of being compressed of first spring to make the stopper by the extrusion enter into the strength of spacing spout bigger and bigger.

The invention relates to a design of a first gear, a first rotating shaft, a volute spiral spring, a driving cylinder, a triangular deflector rod, a limiting block and a one-way clutch ring, which comprises the following steps: the first gear drives the driving cylinder to rotate through the first rotating shaft and the volute spiral spring, the triangular deflector rod rotates along with the driving cylinder, and the rotating direction of the driving cylinder is set to be clockwise; the driving cylinder drives the triangular billboard to rotate clockwise; the design purpose of the unidirectional clutch ring is as follows: the driving cylinder is allowed to rotate clockwise, and the driving cylinder is forbidden to rotate anticlockwise, so that the triangular billboard is guaranteed not to rotate anticlockwise.

Inclined plane and triangle driving lever matched with effect on the stopper: firstly, when the first rotating shaft does not rotate and the driving cylinder does not rotate, the volute spiral spring is in a natural state, and the triangular deflector rod is in contact with the inclined plane of a limiting block; secondly, when the first rotating shaft rotates, the first rotating shaft drives the driving cylinder to rotate through the volute spiral spring, and at the moment, because the first spring is compressed, the triangular shifting lever on the driving cylinder is difficult to extrude the limiting block into the limiting sliding groove, so that the triangular shifting lever and the driving cylinder cannot rotate, and the volute spiral spring is compressed to store energy; thirdly, when the volute spiral spring is compressed to a certain amount, the volute spiral spring can completely push the limiting block into the limiting sliding groove by the poking force provided by the driving cylinder to the triangular poking rod, and then the first rotating shaft can cross the limiting block through the volute spiral spring, the driving cylinder and the triangular poking rod; fourthly, after the triangular shifting lever crosses the corresponding limit block, the driving cylinder and the triangular shifting lever can rapidly rotate to the position of the next limit block under the continuous rotation of the second rotating shaft and the reset of the volute spiral spring, and then the triangular shifting lever is contacted and matched with the inclined plane of the limit block again.

According to the invention, the larger the force of the limiting block which is extruded into the limiting sliding groove is, the larger the compression amount of the volute spiral spring needs to be, and finally the first rotating shaft needs more time to rotate and store energy, so that the time that the first rotating shaft sequentially passes through the limiting block through the volute spiral spring, the driving cylinder and the triangular shifting rod is longer and longer, the frequency of the driving cylinder driving the triangular advertising board to rotate and switch is slowed down, and the advertising effect of the triangular advertising board under different conditions is met.

The design of three stopper along circumferential direction for the rotation angle that the driving cylinder crossed behind each stopper through the triangle driving lever is 120 degrees, and then makes the rotation angle that the driving cylinder drove the triangle bill-board set at 120 degrees, satisfies the purpose that the triangle bill-board propagated the trilateral advertisement of triangle bill-board through rotatory switching.

The billboard is arranged on the top of a taxi. When the taxi does not run, the blade does not drive the first ring sleeve to rotate, the first rotating shaft does not rotate, the volute spiral spring is in a natural state, the triangular deflector rod is in contact with the inclined plane of the limiting block, and the advertisement surfaces on the two sides of the triangular billboard are publicized to the outside at the moment.

Setting: when a taxi runs, the blades are blown by wind to drive the first ring sleeve to rotate anticlockwise; when the running speed of the taxi reaches 30km/h, the first centrifugal wheel just can not drive the second rotating shaft to rotate through the centrifugal block.

When a taxi runs at a low speed, the blades are blown by wind to drive the first ring sleeve to rotate anticlockwise, the first ring sleeve drives the first centrifugal wheel to rotate anticlockwise through the connecting rod, the first centrifugal spring and the centrifugal block rotate along with the first centrifugal wheel, at the moment, the first centrifugal wheel can drive the second rotating shaft to rotate anticlockwise through the centrifugal block, and the second rotating shaft drives the first gear to rotate clockwise through the second gear. First gear drives first pivot clockwise rotation, and first pivot drives the driving barrel rotation through volute spiral spring, and because first spring is compressed this moment, the triangle driving lever on the driving barrel is difficult to extrude the stopper and enter into spacing spout, so triangle driving lever and driving barrel can not rotate, and volute spiral spring is compressed the energy storage. When the volute spiral spring is compressed to a certain amount, the volute spiral spring can completely enable the limiting block to be extruded into the limiting sliding groove through the poking force provided by the driving cylinder to the triangular poking rod, and then the first rotating shaft can cross the limiting block through the volute spiral spring, the driving cylinder and the triangular poking rod. After the limiting block is extruded into the limiting sliding groove and the triangular shifting rod passes over the limiting block, the limiting block moves and resets under the action of the first spring. After the triangle driving lever crosses the corresponding limiting block, the driving cylinder and the triangle driving lever can rapidly rotate to the position of the next limiting block under the continuous rotation of the second rotating shaft and the reset of the volute spiral spring, then the triangle driving lever is contacted and matched with the inclined plane of the limiting block again, and the rotating angle of the driving cylinder is 120 degrees at the moment. Then the driving cylinder drives the triangular billboard to rotate 120 degrees, the triangular billboard drives the fixed rod to rotate, and the triangular billboard is rotated and switched to propagate the advertisement on the other side of the triangular billboard. When the triangular billboard rotates and is switched next time, the process that the triangular deflector rod passes over the limiting block after the scroll spring is compressed to a certain amount is repeated.

When the running speed of the taxi exceeds 30km/h, the first ring sleeve drives the first centrifugal wheel to still rotate anticlockwise through the connecting rod, but the first centrifugal wheel cannot drive the second rotating shaft to rotate through the centrifugal block, so that the second rotating shaft does not rotate any more, the second rotating shaft does not input power any more, and the triangular billboard does not rotate and is switched. Such a design has the advantages that: when the running speed of the taxi exceeds 30km/h, pedestrians cannot easily see the advertising words of the triangular billboard clearly, the function of rotating and switching the triangular billboard has no better effect, and therefore, after the running speed of the taxi exceeds 30km/h, the triangular billboard stops rotating and switching. In addition, the design that the triangular billboard stops rotating also avoids the action that the triangular billboard still does not stop rotating and switching after the running speed of the taxi exceeds 30km/h, thereby reducing the structural wear of the triangular billboard caused by long-time rotating and switching; the service life of the related structure is prolonged equivalently when the triangular billboard is switched in a rotating way.

The one-way clutch ring can limit the counterclockwise rotation of the triangular billboard, and the clockwise rotation of the triangular billboard can pass through the corresponding limit block after the scroll spring stores enough energy; when the external action causes the clockwise rotation triangular billboard to be in, the clockwise rotation switching of the triangular billboard needs enough energy, so that the general external action is not enough to cause the clockwise rotation switching of the triangular billboard, thereby greatly reducing the possibility that the triangular billboard can be freely rotated and switched after being influenced by the external action. When the triangular billboard is switched clockwise, the driving cylinder can completely drive the triangular billboard to rotate 120 degrees quickly under the reset force of the scroll spring, and the reset action of the scroll spring can compensate the error of the triangular billboard during rotation switching, so that the triangular billboard is ensured to rotate 120 degrees every time.

Compared with the traditional billboard technology, the triangular billboard can stop rotating and switching when a taxi runs at a high speed, and intermittently rotate and switch when the taxi runs at a low speed, so that the triangular billboard can effectively propagate three-side advertisements, and the advertising benefit is greatly increased. In addition, the driver can promote through rotatory adjustable ring and be pushed away the ring to the compression capacity of increase first spring makes first pivot cross the time of stopper more and more long through spiral spring, drive cylinder and triangle driving lever in proper order, and the frequency that the drive cylinder drove the rotatory switching of triangle bill-board becomes slow, thereby satisfies the advertising effect of triangle bill-board under the different situation. The invention has simple structure and better use effect.

The triangular billboard 4 is provided with an illumination system. The design is convenient for the taxi to pass through the lighting system at night, so that the pedestrians can still see the advertising words on the triangular billboard 4.

The first centrifugal spring 34 is a compression spring; the first centrifugal spring 34 is always in a compressed state. The design is that: firstly, when the first centrifugal wheel 18 is not rotated, the centrifugal block 33 tightly presses the second rotating shaft 19 under the action of the first centrifugal spring 34; secondly, when the first centrifugal wheel 18 rotates slowly, after the pressure of the first centrifugal spring 34 is offset by the centrifugal force generated by the centrifugal block 33, the extrusion force of the centrifugal block 33 on the second rotating shaft 19 can still ensure that the centrifugal block 33 can drive the second rotating shaft 19 to rotate; third, when the first centrifugal wheel 18 rotates rapidly, after the centrifugal force generated by the centrifugal block 33 cancels the pressure of the first centrifugal spring 34, the pressing force of the centrifugal block 33 on the second rotating shaft 19 is not enough to ensure that the centrifugal block 33 can drive the second rotating shaft 19 to rotate, and further the rotation of the first centrifugal wheel 18 cannot drive the second rotating shaft 19 to rotate via the centrifugal block 33.

The inner circular surface of the pushed ring 58 is a smooth surface; the surface of the pushed ring 58 in contact with the adjusting ring 46 is coated with a lubricating oil. Since the internal thread of the adjusting ring 46 is threadedly engaged with the external thread of the annular groove 60, when the adjusting ring 46 is adjusted by the user, the adjusting ring 46 moves along the axis of the fixed ring sleeve 45 toward the pushed ring 58 under the action of the threaded engagement, and the adjusting ring 46 pushes the pushed ring 58 to move toward the stopper 54, so that the first spring 57 continues to be compressed. The surface of the pushed ring 58 in contact with the adjusting ring 46 is coated with a lubricating oil so that when the adjusting ring 46 rotationally pushes the pushed ring 58, the adjusting ring 46 does not rotate the pushed ring 58, thereby ensuring that the first spring 57 can be smoothly compressed. The inner circular surface of the pushed ring 58 is smooth to ensure that the pushed ring 58 can be pushed smoothly.

The first spring 57 is a compression spring, and the first spring 57 is always in a compressed state.

As shown in fig. 5, the diameter of the first gear 47 is 15 to 18 times the diameter of the second gear 28. The design is that: during the rotation of the second gear 28, the second gear 28 drives the first gear 47 to rotate at a slower speed, so as to ensure that the first gear 47 can be driven to rotate for about one turn after the second gear 28 rotates for many turns, so that the first gear 47 can drive the triangular shifting lever 53 to pass through the corresponding limit block 54 after a period of time elapses through the first rotating shaft 48, the spiral spring 52 and the driving cylinder 42.

The design of the first ring sleeve 16, the connecting rod 15, the first centrifugal wheel 18, the first centrifugal spring 34, the centrifugal block 33, the second gear 28 and the second rotating shaft 19 in the invention is as follows: the first ring sleeve 16 drives the first centrifugal wheel 18 to rotate through the connecting rod 15, and the first centrifugal spring 34 and the centrifugal block 33 rotate along with the first centrifugal wheel 18; when the first ring sleeve 16 rotates slowly, the first centrifugal wheel 18 can drive the second rotating shaft 19 to rotate through the centrifugal block 33, and the second rotating shaft 19 drives the second gear 28 to rotate; when the rotation speed of the first ring 16 gradually increases and reaches a certain threshold value, the first centrifugal wheel 18 cannot drive the second rotating shaft 19 to rotate via the centrifugal block 33, and at this time, the first centrifugal wheel 18 still drives the first centrifugal spring 34 and the centrifugal block 33 to rotate.

For the design of the adjusting ring 46, the pushed ring 58, the first spring 57, the guide block 55 and the stop block 54: because the first spring 57 is always in a compressed state, the guide block 55 is located at the deepest position of the guide groove 56 under the action of the first spring 57 and the limiting block 54, so that the guide block 55 is ensured not to be separated from the guide groove 56, and the limiting block 54 is further enabled not to be separated from the limiting sliding groove 59 under the reset force of the first spring 57. The adjustment ring 46 pushes the pushed ring 58 to move toward the stopper 54, so as to further adjust the amount of compression of the first spring 57, and thus the stopper 54 is pushed into the stopper chute 59 with a greater force.

The design of the first gear 47, the first rotating shaft 48, the volute spring 52, the driving cylinder 42, the triangular shift lever 53, the limit block 54 and the one-way clutch ring 43 in the invention is as follows: the first gear 47 drives the driving cylinder 42 to rotate through the first rotating shaft 48 and the spiral spring 52, and the triangular shift lever 53 rotates along with the driving cylinder 42, as shown in fig. 8, the rotating direction of the driving cylinder 42 at this time is set to be clockwise; the driving cylinder 42 drives the triangular billboard 4 to rotate clockwise; the design of the one-way clutch ring 43 aims at: the clockwise rotation of the driving cylinder 42 is allowed and the counterclockwise rotation of the driving cylinder 42 is prohibited, thereby ensuring that the triangular signboard 4 does not rotate counterclockwise.

Inclined plane 61 on stopper 54 and triangle driving lever 53 matched with effect: first, when the first rotating shaft 48 does not rotate and the driving cylinder 42 does not rotate, the spiral spring 52 is in a natural state, and the triangular shift lever 53 contacts with the inclined surface 61 of a stopper 54; secondly, when the first rotating shaft 48 rotates, the first rotating shaft 48 drives the driving cylinder 42 to rotate through the spiral spring 52, at this time, because the first spring 57 is compressed, the triangular shift lever 53 on the driving cylinder 42 is difficult to extrude the limiting block 54 into the limiting sliding groove 59, then the triangular shift lever 53 and the driving cylinder 42 cannot rotate, and the spiral spring 52 is compressed to store energy; thirdly, when the spiral spring 52 is compressed to a certain amount, the shifting force provided by the spiral spring 52 to the triangular shifting rod 53 through the driving cylinder 42 at this time can completely extrude the stopper 54 into the stopper chute 59, and the first rotating shaft 48 can cross over the stopper 54 through the spiral spring 52, the driving cylinder 42 and the triangular shifting rod 53; fourthly, after the triangular shift lever 53 passes over the corresponding stopper 54, the driving cylinder 42 and the triangular shift lever 53 can be rapidly rotated to the position of the next stopper 54 under the continuous rotation of the second rotating shaft 19 and the return of the spiral spring 52, and then the triangular shift lever 53 is again in contact with and engaged with the inclined surface 61 of the stopper 54.

According to the invention, the increase and adjustment of the compression amount of the first spring 57 can ensure that the force of the limiting block 54 which is extruded into the limiting sliding groove 59 is larger, and further the compression amount of the scroll spring 52 is required to be larger, and finally the first rotating shaft 48 needs more time to rotate and store energy, so that the time that the first rotating shaft 48 sequentially passes through the limiting block 54 through the scroll spring 52, the driving cylinder 42 and the triangular shifting lever 53 is longer and longer, the frequency of the driving cylinder 42 driving the triangular advertising board 4 to rotate and switch is slower, and the advertising effect of the triangular advertising board 4 under different conditions is met.

The design of three stopper 54 along the circumferential direction for the rotation angle that the driving cylinder 42 crossed behind each stopper 54 through triangle driving lever 53 is 120 degrees, and then makes the rotation angle that the driving cylinder 42 drove triangle bill-board 4 set at 120 degrees, satisfies the purpose that triangle bill-board 4 propaganda triangle bill-board 4's trilateral advertisement through rotatory switching.
