Description
Technical Field
The invention belongs to the technical field of bicycle bells, and particularly relates to a noise-reducing environment-friendly bicycle bell based on impact sounding.
Background
When the traditional bicycle bell is used at present, the size of the bell can not be adjusted basically, and the sound of different bells is different. For some bells with large ring tones, when a rider encounters children or old people walking slowly in front of the bells in the riding process, the large ring tones can frighten the children or the old people to jump once after the rider makes the bells sound, and certain influence is caused on the children or the old people to smoothly avoid a bicycle; however, a bell with a large ring tone is advantageous for use in noisy traffic environments or relatively congested urban environments. In order to prevent the sound of a big bell from scaring children or the old, and to meet the requirement of noisy traffic environment, it is necessary to design a bell with adjustable sound. In addition, the environment is greatly promoted in China at present, and the bicycle bell with large sound is noise pollution, so that the bicycle bell can achieve the effect of changing the sound from small to large and can also achieve a certain noise reduction effect.
The invention designs a noise-reducing environment-friendly bicycle bell based on impact sound production to solve the problems.

The bell can be mounted on the bicycle by mounting the retaining ring on the handlebar.
As a further improvement of the present technique, when the first scroll spring is not compressed and deformed, the arcuate teeth on the dial do not engage the first gear.
As a further improvement of the technology, the impact balls are spaced from the peripheral cavity surfaces of the rectangular cavity. After the impact block impacts the arc-shaped bulge, the impact ball can be in clearance collision with the cavity surface of the rectangular cavity by the vibration of the impact block; in the process of impact of the impact ball and the cavity surface of the rectangular cavity, the elastic deformation of the second elastic plate can meet the reciprocating impact of the impact ball. In addition, the rectangular cavity and the impact ball in the impact block are designed to generate sound after the impact block impacts, and then the impact ball can collide with the cavity surface of the rectangular cavity by the vibration of the impact block, so that the sound generated after the impact ball impacts can be superposed with the sound generated after the impact block impacts, and the sound generated after the impact block impacts integrally is increased.
As a further improvement of the technology, when the heavy rotation wheel does not start to rotate, the part of the steel wire rope, which is positioned in the sleeve sliding groove, is in a loose state. The design is that in the process of starting rotation of the heavy rotation wheel, the loose steel wire rope cannot pull the rectangular clamping sleeve to move towards the direction far away from the impact block, so that the sound emitted by the impact block in the starting impact stage is relatively small; in addition, the steel wire rope in a loose state can increase the number of times of shifting the shifting plate, and the requirement that the bell needs to be shifted by high frequency continuously under special conditions to enable the rectangular clamping sleeve to move to the bottom of the clamping sleeve sliding groove is met.
As a further improvement of this technique, the above-mentioned ferrule spring is a compression spring.
As a further improvement of the technology, the arc-shaped bulge, the impact block and the impact ball are all made of metal materials. The sound produced by the metal material of the impact block and the impact ball vibrating after the impact block impacts the arc-shaped protrusion is more distinct than other materials.
As a further improvement of the technology, the arc-shaped bulge, the impact block and the impact ball are all made of iron.
As a further improvement of the present technology, the first elastic plate and the rectangular through groove of the rectangular ferrule are in a fitted and nested state. The design is that the part of the first elastic plate in the rectangular through groove of the rectangular cutting sleeve is tightly clamped and cannot swing.
The design of the shifting plate, the swing rod, the first scroll spring, the driving wheel, the arc-shaped tooth, the first gear, the second rotating shaft, the second gear, the one-way clutch ring and the heavy rotating wheel is as follows: the shifting plate rotates along the circle center of the driving wheel under the action of external force, the shifting plate drives the driving wheel to rotate through the oscillating bar, and the first volute spiral spring is compressed; the first scroll spring has the function that under the reset force of the first scroll spring, the driving wheel drives the shifting plate to move and reset through the swing rod. The arc-shaped tooth is matched with the first gear, firstly, when the first scroll spring is not compressed and deformed, the arc-shaped tooth on the driving wheel is not meshed with the first gear, and then when the driving wheel is reset and stops rotating, the driving wheel cannot be driven to rotate by the reverse rotation of the first gear; secondly, after the arc-shaped engaging tooth is meshed with the first gear, the driving wheel drives the first gear to rotate. After the driving wheel drives the first gear to rotate, the first gear drives the second rotating shaft to rotate; under the one-way action of the one-way clutch ring, the second rotating shaft can only drive the second gear to rotate along the driven direction of the first gear through the first one-way clutch ring; when the second rotating shaft rotates reversely, the second rotating shaft cannot drive the second gear to rotate through the one-way clutch ring. The outer circular surface of one end of the heavy rotating wheel close to the second scroll spring is provided with a tooth; the teeth on the heavy rotation wheel mesh with the second gear, and then the second gear drives the heavy rotation wheel to rotate after the second gear rotates in a direction in which the first gear is driven.
The second volute spiral spring and the heavy rotating wheel are designed to be heavier: when the heavy rotation wheel is driven by the second gear to rotate rapidly, the second scroll spring is compressed; when the drive wheel resets rotatoryly under the power that resets of first scroll spring, the drive wheel is through arc rodent, first gear drives second pivot reverse rotation, the second pivot can't continue to drive the heavy swiveling wheel rotation through one-way clutch ring and second gear this moment, because the heavy of heavy swiveling wheel, so the rotatory kinetic energy of heavy swiveling wheel is bigger, and the rotatory kinetic energy of heavy swiveling wheel this moment is greater than the hindrance energy and the bellied hindrance energy sum of arc of second scroll spring, so the heavy swiveling wheel can continue to rotate along original direction of rotation, only under the bellied hindrance of second scroll spring and arc, the rotation rate of heavy swiveling wheel can slow down gradually. For the shifting plate, when a rider continuously shifts the shifting plate, the gap shifting time of the shifting plate is about 1 second generally; in the gap time of about 1 second, the heavy rotating wheel is not completely stopped, so that the second gear can drive the heavy rotating wheel to rotate in a clearance mode in the process that a rider continuously stirs the shifting plate, and the rotating direction of the heavy rotating wheel is always unchanged. When the rider does not stir the shifting plate any more, the second gear does not drive the heavy rotating wheel to rotate any more, and then the heavy rotating wheel can be gradually stopped under the obstruction of the second volute spiral spring and the arc-shaped bulge; when the heavy rotation wheel stops rotating, the compression deformation of the second scroll spring stops, and then the second scroll spring makes the heavy rotation wheel rotate reversely under the reset force of the second scroll spring until the second scroll spring can not drive the heavy rotation wheel to rotate reversely any more.
For the adjustment mechanism: the steel wire rope moves towards the direction far away from the impact block by pulling the rectangular clamping sleeve, and then the length of the first elastic plate between the impact block and the rectangular clamping sleeve is adjusted, so that the swing amplitude allowed by the first elastic plate between the impact block and the rectangular clamping sleeve is different, the vibration amplitude of the impact block is different, and the sound generated after the impact block is impacted is different. In the process that the rectangular cutting sleeve moves towards the direction far away from the impact block, the cutting sleeve spring is compressed; the ferrule spring displaces the rectangular ferrule back when the ferrule spring is no longer compressed.
The inner circle surface of the friction sleeve is provided with a friction surface, the outer circle surface of the first rotating shaft in the friction sleeve is a friction surface, and the friction surface on the first rotating shaft is matched with the friction sleeve to play a role of: the friction surface on the first rotating shaft is in friction fit with the inner circular surface of the friction sleeve, and the friction force is larger, so that the first rotating shaft is limited and cannot rotate, when the heavy rotating wheel just starts to rotate, the heavy rotating wheel cannot drive the first rotating shaft to rotate, and the heavy rotating wheel rotates around the axis of the first rotating shaft; second, after the heavy swiveling wheel rotated certain number of turns, after the number of turns that wire rope twined on first pivot reached the limit, the torsional force that heavy swiveling wheel transmitted first pivot through wire rope will be greater than the first pivot by the spacing frictional force of friction sleeve, so heavy swiveling wheel can drive first pivot rotation through wire rope.
After the impact block and the arc-shaped bulge are impacted, the arc-shaped bulge can cause the vibration of the bell cover to sound, but because the bell cover is fixedly arranged on the base, the vibration amplitude of the bell cover is very small, the sound generated by the vibration of the bell cover is relatively small, and the sound generated by the vibration of the impact block cannot be obviously influenced; that is, the bell sound of the bell of the present invention is mainly derived from the sound generated after the impact of the impact block.
When the shifting plate is not shifted, the first scroll spring and the second scroll spring are both in an uncompressed state, the heavy rotating wheel does not start to rotate, and the part of the steel wire rope, which is positioned in the sleeve sliding groove, is in a relaxed state; the arc-shaped rodent on the poking wheel is not in a meshing relationship with the first gear; the length of the first elastic plate between the impact block and the rectangular clamping sleeve is smaller.
When the shifting plate is shifted under the action of external force, the shifting plate drives the driving wheel to rotate through the oscillating bar, the first volute spiral spring is compressed, the arc-shaped tooth is meshed with the first gear, the driving wheel drives the second rotating shaft to rotate through the first gear, the second rotating shaft drives the second gear to rotate through the one-way clutch ring, and the second gear drives the heavy rotating wheel to rotate. The heavy rotating wheel drives the impact block to rotate through the first elastic plate, the impact block impacts the arc-shaped bulge, and under the elastic deformation of the first elastic plate, the impact block can cross the arc-shaped bulge; after the impact block impacts the arc-shaped bulge, the impact block generates vibration, the impact block makes sound, the vibration of the impact block enables the impact ball to be in clearance collision with the cavity surface of the rectangular cavity, the impact ball also makes sound when colliding with the cavity surface of the rectangular cavity, the sound generated after the impact ball impacts can be superposed with the sound generated after the impact block impacts, and the sound generated after the impact block is impacted integrally is increased. Because the part of the first elastic plate, which is positioned in the rectangular through groove of the rectangular cutting sleeve, is tightly clamped and cannot swing, the length of the first elastic plate between the impact block and the rectangular cutting sleeve is smaller, and the allowable swinging amplitude of the first elastic plate between the impact block and the rectangular cutting sleeve is small, the vibration amplitude generated after the impact block impacts the arc-shaped bulge is also smaller, and under the condition, the sound generated after the impact block impacts is smaller.
In the initial stage, the first rotating shaft is limited by friction of the friction sleeve, and the first rotating shaft does not rotate at the moment. In the process that the heavy rotating wheel just starts to rotate, the heavy rotating wheel can drive the steel wire rope to rotate around the axis of the first rotating shaft, and the steel wire rope is wound on the first rotating shaft step by step. Because the part of the steel wire rope, which is positioned in the cutting sleeve sliding groove, is in a loose state in an initial state, the part of the steel wire rope, which is positioned in the cutting sleeve sliding groove, is in a tensioned state after being wound for four turns; along with, first pivot continues winding wire rope, and wire rope removes to the direction of keeping away from the striking block through pulling rectangular cutting ferrule, and the cutting ferrule spring is compressed, and the length of the first elastic plate between striking block and the rectangular cutting ferrule becomes long gradually, and the amplitude of oscillation that the first elastic plate between striking block and the rectangular cutting ferrule allowed becomes big gradually, and the amplitude of vibration that produces behind the striking block striking arc arch becomes big gradually, and under such a condition, the sound that the striking block produced after producing the striking also can become gradually.
The second wrap spring is compressed during rotation of the second gear driven heavy duty wheel.
After the steel wire rope with the limited number of circles is wound on the outer circular surface of the first rotating shaft, the steel wire rope pulls the rectangular clamping sleeve to move to the bottom position close to the clamping sleeve sliding groove in the direction far away from the impact block, the rectangular clamping sleeve cannot continue to move in the direction far away from the impact block, the length of the first elastic plate between the impact block and the rectangular clamping sleeve is longest, the allowed swing amplitude of the first elastic plate between the impact block and the rectangular clamping sleeve is the largest, the vibration amplitude generated after the impact block impacts the arc-shaped protrusion is the largest, and under the condition, the sound generated after the impact block impacts is the largest. After the number of turns of the steel wire rope wound on the first rotating shaft reaches the limit, the torsional force transmitted to the first rotating shaft by the heavy rotating wheel through the steel wire rope is larger than the friction force of the first rotating shaft limited by the friction sleeve, and then the heavy rotating wheel drives the first rotating shaft to rotate through the steel wire rope. Because the heavy rotation wheel and the first rotation shaft realize synchronous rotation, the steel wire rope is not wound on the outer circular surface of the second ring sleeve any more, the steel wire rope does not pull the rectangular clamping sleeve to move in the direction far away from the impact block any more, the length of the first elastic plate between the impact block and the rectangular clamping sleeve is kept unchanged, and the sound emitted after the impact block is impacted is kept unchanged.
When the shifting plate continues to shift, the second gear continues to drive the heavy rotating wheel to rotate, and the first rotating shaft continues to rotate; however, in such a case, the steel wire rope still does not wind on the outer circumferential surface of the first rotating shaft, and the sound generated after the impact block impacts will remain unchanged.
For the bicycle bell, under the condition that the dialing plate is just dialed, the sound emitted by the striking block is small, so that passers are prevented from suddenly hearing a large bell to scare for one jump, the speed of avoiding the passers from being influenced, and the condition that the passers collide with the bicycle is avoided. When the passerby does not realize the bell of the trolley, the passerby continues to stir the shifting plate, and the steel wire rope pulls the rectangular clamping sleeve to move towards the direction far away from the impact block; along with the length of the first elastic plate between the impact block and the rectangular clamping sleeve is gradually increased, the allowed swing amplitude of the first elastic plate between the impact block and the rectangular clamping sleeve is gradually increased, the vibration amplitude generated after the impact block impacts the arc-shaped protrusion is gradually increased, under the condition, the sound emitted after the impact block impacts is also gradually increased, and the road people who do not realize the ring of the small vehicle can gradually realize the ring of the large vehicle and can smoothly avoid bicycles due to the gradual increase of the ring of the vehicle. When the large vehicle bell still cannot make passerby aware of the situation, a rider can continue to increase the frequency of shifting the shifting plate, the steel wire rope pulls the rectangular clamping sleeve to move to a position close to the bottom of the clamping sleeve sliding groove in the direction away from the impact block, the length of the first elastic plate between the impact block and the rectangular clamping sleeve is longest, the allowed swing amplitude of the first elastic plate between the impact block and the rectangular clamping sleeve is the largest, the vibration amplitude generated after the impact block impacts the arc-shaped bulge is the largest, and under the condition, the sound generated after the impact block impacts is the arc-shaped bulge is the largest; passers-by may still not be aware of the largest car ring, or passers-by may not ignore the largest car ring; under this condition, the passerby probably will continue to increase to stir the board, in order to prevent that the sound that the striking piece sent from surpassing the limit to and prevent that rectangular cutting ferrule from having reached the bottom position of cutting ferrule sliding tray, the continuation winding of wire rope probably harms rectangular cutting ferrule, so when the bell sound reaches the biggest, wire rope no longer continues to be twined, has protected the inner structure of bell, and the ring sound also maintains to the biggest and does not break through the limit, has avoided bigger noise pollution. In addition, the automobile ring tone is small at first, and can also respond to the environmental call, so that certain noise pollution is reduced.
When the shifting plate is not shifted any more, the driving wheel drives the shifting plate to move and reset through the oscillating bar under the reset force of the first volute spiral spring. When the second gear does not drive the heavy rotating wheel any more, the heavy rotating wheel can be gradually stopped under the obstruction of the second volute spiral spring and the arc-shaped bulge; when the heavy rotating wheel stops rotating, the first rotating shaft also stops rotating, and the reset force of the second scroll spring is smaller than the limit friction force of the friction sleeve on the first rotating shaft, so that when the heavy rotating wheel is prepared to rotate reversely by the second scroll spring, the reset force of the second scroll spring is not enough to drive the first rotating shaft to rotate through the heavy rotating wheel; the second scroll spring can only make the heavy rotating wheel rotate reversely; when the second scroll spring is released, the heavy rotating wheel rotates reversely to enable the impact block to impact the last arc-shaped bulge, and at the moment, the residual reset energy of the second scroll spring still enables the impact block to cross the last arc-shaped bulge, so that the second scroll spring can enable the impact block to rotate and reset to the original position through the heavy rotating wheel. In the process that the heavy rotating wheel rotates reversely, the steel wire rope wound on the first rotating shaft is released; after the heavy rotation wheel stops rotating reversely, the steel wire rope wound on the second sleeve is also released, under the action of gravity of the steel wire rope, the steel wire rope on the upper side of the heavy rotation wheel is basically in a tensioned state under the action of gravity, and the part of the steel wire rope, which is positioned in the sleeve sliding groove, is in a loose state.
Compared with the traditional bell technology, the vibration amplitude of the impact block is controlled by the swing amplitude allowed by the first elastic plate between the impact block and the rectangular clamping sleeve, and the control on the sound intensity is further realized. In the adjusting mechanism, the steel wire rope moves towards the direction far away from the impact block by pulling the rectangular clamping sleeve, and then the length of the first elastic plate between the impact block and the rectangular clamping sleeve is adjusted, so that the swing amplitude allowed by the first elastic plate between the impact block and the rectangular clamping sleeve is different, the vibration amplitude of the impact block is different, and the sound generated after the impact block is impacted is different. The design that the sound emitted by the impact block is changed from small to big is characterized in that passers are prevented from hearing a big bell suddenly and frightening one jump to influence the speed of avoiding the passers from the bicycle, and the condition that the bicycle bumps into the passers is avoided; the gradual increase of the vehicle ring can enable passers who do not realize the small vehicle ring to gradually realize the big vehicle ring, so that the passers can smoothly avoid bicycles. In addition, the automobile ring tone is small at first, and can also respond to the environmental call, so that certain noise pollution is reduced. The invention has simple structure and better use effect.

The inner circumferential surface of the friction sleeve 60 has a friction surface; the outer circular surface of the first rotating shaft 61 in the friction sleeve 60 is a friction surface; the friction surface on the first shaft 61 is engaged with the friction sleeve 60.
As shown in fig. 9, 10, 13 and 14, the adjusting mechanism 15 comprises a wire rope 35, a rectangular ferrule 27, a first elastic plate 28, an impact block 29, a rectangular cavity 30, a second elastic plate 31, an impact ball 32, a ferrule spring 51 and a rectangular through slot 52, as shown in fig. 10 and 13, wherein the rectangular ferrule 27 is installed in the rectangular guide rail in a sliding fit manner; one end of the rectangular cutting sleeve extends out of the rectangular guide rail 26, and the other end of the rectangular cutting sleeve is positioned in the cutting sleeve sliding groove 25; the rectangular cutting sleeve 27 is provided with a rectangular through groove 52; as shown in fig. 10 and 14, one end of the first elastic plate 28 is mounted on the bottom groove surface of the ferrule sliding groove 25, and the other end thereof passes through the rectangular through groove 52 of the rectangular ferrule 27 and is mounted with the striking block 29; as shown in fig. 14, the impact block 29 has a rectangular cavity 30 therein; one end of the second elastic plate 31 is arranged on the side cavity surface of the rectangular cavity 30 close to the first elastic plate 28, and the other end is provided with an impact ball 32; as shown in fig. 12 and 13, one end of each of the two ferrule springs 51 is mounted on the end surface of the rectangular ferrule 27, and the other end is mounted on the bottom groove surface of the ferrule sliding groove 25; two ferrule springs 51 are located on both sides of the first resilient plate 28, and both ferrule springs 51 are located in the ferrule sliding groove 25; as shown in fig. 10, one end of the wire rope 35 is mounted on the rectangular ferrule 27 on the end surface of the ferrule sliding groove 25, and the other end is connected to the outer circumferential surface of the first rotating shaft 61 via the first fixed pulley 33 and the second fixed pulley 34; the impact block 29 cooperates with the arc-shaped protrusion 9.

The bell can be mounted on the bicycle by mounting the fixing ring 1 on the handlebar.
As shown in FIG. 8, when the first scroll spring 20 is not compressed and deformed, the arcuate teeth 22 on the dial do not engage the first gear 19.
As shown in FIG. 14, the impact ball 32 is spaced from the peripheral cavity surfaces of the rectangular cavity 30. Then the shock of the impact block 29 can cause the impact ball 32 to intermittently collide with the cavity surface of the rectangular cavity 30 after the impact block 29 collides with the arc-shaped protrusion 9; the elastic deformation of the second elastic plate 31 can satisfy the reciprocal impact of the impact ball 32 during the impact of the impact ball 32 with the cavity surface of the rectangular cavity 30. In addition, the rectangular cavity 30 and the impact ball 32 in the impact block 29 are designed so that sound is generated after the impact block 29 impacts, and then the impact ball 32 impacts the cavity surface of the rectangular cavity 30 due to the vibration of the impact block 29, so that the sound generated after the impact of the impact ball 32 can be superimposed on the sound generated after the impact of the impact block 29, and the sound generated after the impact of the impact block 29 as a whole is increased.
As shown in fig. 10, when the re-rotation wheel 14 does not start rotating, the portion of the wire rope 35 located in the ferrule sliding groove 25 is in a relaxed state. The design is that during the initial rotation of the heavy rotation wheel 14, the loose steel wire rope 35 can not pull the rectangular cutting sleeve 27 to move away from the impact block 29, so that the sound generated in the initial impact stage of the impact block 29 is relatively small; in addition, the steel wire rope 35 in a loose state can increase the shifting times of the shifting plate 5, and the requirement that the bell needs to continuously shift the shifting plate 5 at high frequency under special conditions so that the rectangular clamping sleeve 27 can be moved to the bottom of the clamping sleeve sliding groove 25 is met.
The ferrule spring 51 is a compression spring.
The arc-shaped protrusion 9, the impact block 29 and the impact ball 32 are all made of metal materials. The sound produced by the metal material of the impact block 29 and the impact ball 32 after the impact block 29 impacts the arc-shaped protrusion 9 is more distinct than other materials after the impact block 29 and the impact ball are vibrated.
The arc-shaped protrusion 9, the impact block 29 and the impact ball 32 are all made of iron.
The first elastic plate 28 is in a fit-nesting state with the rectangular through groove 52 of the rectangular ferrule 27. This is so that the portion of the first resilient plate 28 that is located in the rectangular channel 52 of the rectangular ferrule 27 is tightly captured against wobbling.
The design of the poking plate 5, the swing rod 6, the first scroll spring 20, the driving wheel 10, the arc-shaped tooth 22, the first gear 19, the second rotating shaft 17, the second gear 13, the one-way clutch ring 12 and the heavy rotating wheel 14 in the invention is as follows: the shifting plate 5 rotates along the circle center of the driving wheel 10 under the action of external force, the shifting plate 5 drives the driving wheel 10 to rotate through the oscillating bar 6, and the first volute spiral spring 20 is compressed; the first scroll spring 20 has the function that under the reset force of the first scroll spring 20, the driving wheel 10 drives the shifting plate 5 to move and reset through the swing rod 6. The arc-shaped tooth 22 is matched with the first gear 19 in that firstly, when the first scroll spring 20 is not compressed and deformed, the arc-shaped tooth 22 on the driving wheel 10 is not meshed with the first gear 19, so that when the driving wheel 10 is reset and stops rotating, the reverse rotation of the first gear 19 can not drive the driving wheel 10 to rotate; secondly, when the arc-shaped tooth 22 is engaged with the first gear 19, the driving wheel 10 drives the first gear 19 to rotate. After the driving wheel 10 drives the first gear 19 to rotate, the first gear 19 drives the second rotating shaft 17 to rotate; under the unidirectional action of the unidirectional clutch ring 12, the second rotating shaft 17 can only drive the second gear 13 to rotate along the driven direction of the first gear 19 through the first unidirectional clutch ring 12; when the second rotating shaft 17 rotates in the reverse direction, the second rotating shaft 17 cannot drive the second gear 13 to rotate through the one-way clutch ring 12. The outer circumferential surface of the end of the heavy rotation wheel 14 close to the second scroll spring 23 has a mesh; the teeth of the heavy rotation wheel 14 are engaged with the second gear 13, and then the second gear 13 rotates the heavy rotation wheel 14 after the second gear 13 rotates in a direction in which the first gear 19 is driven.
The second wrap spring 23 and the heavy rotor 14 are of a relatively heavy design: when the heavy rotation wheel 14 is rotated fast by the second gear 13, the second scroll spring 23 is compressed; when the driving wheel 10 is rotated again under the returning force of the first scroll spring 20, the driving wheel 10 drives the second rotating shaft 17 to rotate reversely through the arc-shaped tooth 22 and the first gear 19, at this time, the second rotating shaft 17 cannot drive the re-rotation wheel 14 to rotate continuously through the one-way clutch ring 12 and the second gear 13, because of the weight of the re-rotation wheel 14, the rotation kinetic energy of the re-rotation wheel 14 is relatively large, and at this time, the rotation kinetic energy of the re-rotation wheel 14 is greater than the sum of the blocking energy of the second scroll spring 23 and the blocking energy of the arc-shaped protrusion 9, so that the re-rotation wheel 14 continues to rotate in the original rotation direction, and only under the blocking of the second scroll spring 23 and the arc-shaped protrusion 9, the rotation speed of the re-rotation. For the dial plate 5, when the rider continuously dials the dial plate 5, the clearance dialing time of the dial plate 5 is generally about 1 second; however, in the gap time of about 1 second, the re-rotation wheel 14 has not completely stopped, so that the second gear 13 drives the re-rotation wheel 14 to rotate intermittently and the rotation direction of the re-rotation wheel 14 is not changed all the time while the rider keeps toggling the dial plate 5. When the rider does not stir the dial plate 5 any more, the second gear 13 does not drive the heavy rotating wheel 14 to rotate any more, and then the heavy rotating wheel 14 is stopped gradually under the obstruction of the second volute spiral spring 23 and the arc-shaped protrusion 9; when the rotation of the heavy rotation wheel 14 is stopped, the compression deformation of the second scroll spring 23 is stopped, and the second scroll spring 23 reversely rotates the heavy rotation wheel 14 under the restoring force of the second scroll spring 23 until the second scroll spring 23 can no longer drive the heavy rotation wheel 14 to reversely rotate.
For the adjustment mechanism 15: the wire rope 35 moves in a direction away from the impact block 29 by pulling the rectangular cutting sleeve 27, and then the length of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 is adjusted, so that the allowed swing amplitude of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 is different, the vibration amplitude of the impact block 29 is also different, and the sound generated after the impact block 29 is impacted is also different in size. During movement of the rectangular ferrule 27 away from the strike block 29, the ferrule spring 51 is compressed; when the ferrule spring 51 is no longer compressed, the ferrule spring 51 moves the rectangular ferrule 27 back.
The inner circle surface of the friction sleeve 60 is provided with a friction surface, the outer circle surface of the first rotating shaft 61 in the friction sleeve 60 is a friction surface, and the friction surface on the first rotating shaft 61 and the friction sleeve 60 are matched to act as: because the friction surface on the first rotating shaft 61 is in friction fit with the inner circular surface of the friction sleeve 60 and the friction force is relatively large, the first rotating shaft 61 is limited and cannot rotate, when the heavy rotating wheel 14 starts to rotate, the heavy rotating wheel 14 cannot drive the first rotating shaft 61 to rotate, and the heavy rotating wheel 14 rotates around the axis of the first rotating shaft 61; secondly, after the heavy rotation wheel 14 rotates a certain number of times, and the number of times that the steel cable 35 is wound on the first rotation shaft 61 reaches a limit, the torsion force transmitted by the heavy rotation wheel 14 to the first rotation shaft 61 through the steel cable 35 will be greater than the friction force limited by the friction sleeve 60 of the first rotation shaft 61, and then the heavy rotation wheel 14 will drive the first rotation shaft 61 to rotate through the steel cable 35.
After the impact block 29 and the arc-shaped protrusion 9 are impacted, the arc-shaped protrusion 9 may cause the vibration of the bell cover 4 to generate sound, but because the bell cover 4 is fixedly arranged on the base 3, the vibration amplitude of the bell cover 4 is very small, so the sound generated by the vibration of the bell cover 4 is relatively small, and the sound generated by the vibration of the impact block 29 cannot be obviously influenced; that is, the bell sound of the bell of the present invention is mainly derived from the sound generated after the impact of the impact block 29.
The specific implementation mode is as follows: when the dial plate 5 is not dialed, the first scroll spring 20 and the second scroll spring 23 are both in an uncompressed state, the heavy rotating wheel 14 does not start to rotate, and the part of the steel wire rope 35, which is positioned in the ferrule sliding groove 25, is in a relaxed state; the arc-shaped teeth 22 on the dial wheel are not in meshing relationship with the first gear 19; the length of the first resilient plate 28 between the impact block 29 and the rectangular ferrule 27 is relatively small.
When the shifting plate 5 is shifted under the action of external force, the shifting plate 5 drives the driving wheel 10 to rotate through the swing rod 6, the first volute spiral spring 20 is compressed, the arc-shaped tooth 22 is meshed with the first gear 19, the driving wheel 10 drives the second rotating shaft 17 to rotate through the first gear 19, the second rotating shaft 17 drives the second gear 13 to rotate through the one-way clutch ring 12, and the second gear 13 drives the heavy rotating wheel 14 to rotate. The heavy rotation wheel 14 drives the impact block 29 to rotate through the first elastic plate 28, and the impact block 29 impacts the arc-shaped protrusion 9, and under the elastic deformation of the first elastic plate 28, the impact block 29 can cross the arc-shaped protrusion 9; after the impact block 29 impacts the arc-shaped bulge 9, the impact block 29 generates vibration, the impact block 29 makes sound, the vibration of the impact block 29 enables the impact ball 32 to collide with the cavity surface of the rectangular cavity 30 in a clearance mode, the impact ball 32 also makes sound when colliding with the cavity surface of the rectangular cavity 30, the sound generated after the impact ball 32 collides can be superposed with the sound generated after the impact block 29 collides, and the sound generated after the impact block 29 integrally collides is increased. Since the portion of the first elastic plate 28 located in the rectangular through groove 52 of the rectangular ferrule 27 is tightly clamped and does not swing, the length of the first elastic plate 28 between the impact block 29 and the rectangular ferrule 27 is relatively small, and the amplitude of the allowed swing of the first elastic plate 28 between the impact block 29 and the rectangular ferrule 27 is small, the amplitude of the vibration generated after the impact block 29 impacts the arc-shaped protrusion 9 is relatively small, and in such a case, the sound generated after the impact block 29 impacts is relatively small.
At the initial stage, the first rotating shaft 61 is not rotated because the first rotating shaft 61 is frictionally retained by the friction sleeve 60. During the initial rotation of the heavy rotation wheel 14, the heavy rotation wheel 14 rotates the wire rope 35 around the axis of the first rotating shaft 61, and the wire rope 35 is wound around the first rotating shaft 61 step by step. Because the part of the steel wire rope 35 in the ferrule sliding groove 25 is in a loose state in the initial state, the part of the steel wire rope 35 in the ferrule sliding groove 25 is in a tensioned state after being wound for four turns; as the first rotating shaft 61 continues to wind the wire rope 35, the wire rope 35 moves away from the impact block 29 by pulling the rectangular sleeve 27, the sleeve spring 51 is compressed, the length of the first elastic plate 28 between the impact block 29 and the rectangular sleeve 27 gradually increases, the allowable swing amplitude of the first elastic plate 28 between the impact block 29 and the rectangular sleeve 27 gradually increases, the vibration amplitude generated after the impact block 29 impacts the arc-shaped protrusion 9 gradually increases, and in such a case, the sound generated after the impact block 29 impacts also gradually increases.
During the rotation of the heavy rotation wheel 14 driven by the second gear 13, the second wrap spring 23 is compressed.
After the wire rope 35 with the limited number of turns is wound on the outer circumferential surface of the first rotating shaft 61, the wire rope 35 pulls the rectangular cutting sleeve 27 to move to a position close to the bottom of the cutting sleeve sliding groove 25 in the direction away from the impact block 29, the rectangular cutting sleeve 27 cannot move continuously in the direction away from the impact block 29, the length of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 is the longest, the allowed swing amplitude of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 is the largest, the vibration amplitude generated after the impact block 29 impacts the arc-shaped protrusion 9 is the largest, and under the condition, the sound generated after the impact block 29 impacts is also the largest. After the number of turns of the wire rope 35 wound on the first rotating shaft 61 reaches the limit, the torsion force transmitted by the heavy rotating wheel 14 through the wire rope 35 to the first rotating shaft 61 is greater than the friction force of the first rotating shaft 61 limited by the friction sleeve 60, and then the heavy rotating wheel 14 drives the first rotating shaft 61 to rotate through the wire rope 35. Because the heavy rotation wheel 14 and the first rotation shaft 61 realize synchronous rotation, the wire rope 35 will not be wound on the outer circumferential surface of the second loop any more, the wire rope 35 will not pull the rectangular cutting sleeve 27 to move away from the impact block 29, the length of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 will remain unchanged, and the sound generated after the impact block 29 impacts will remain unchanged.
When the shifting plate 5 continues to shift, the second gear 13 continues to drive the heavy rotating wheel 14 to rotate, and the first rotating shaft 61 continues to rotate; however, in such a case, the wire rope 35 still does not wind on the outer circumferential surface of the first rotating shaft 61, and the sound generated after the impact block 29 impacts will remain unchanged.
For the bell of the invention, under the condition that the dialing plate 5 is just dialed, the sound emitted by the striking block 29 is smaller, thus preventing passers from suddenly hearing a big bell to threaten one jump, influencing the speed of avoiding the passers from being ridden by the passers, and avoiding the passers by being bumped by the bicycle. When the passerby does not realize the ring of the trolley, the passerby continues to stir the shifting plate 5, and the steel wire rope 35 pulls the rectangular clamping sleeve 27 to move towards the direction far away from the impact block 29; as the length of the first elastic plate 28 between the striking block 29 and the rectangular sleeve 27 is gradually increased, the allowable swing amplitude of the first elastic plate 28 between the striking block 29 and the rectangular sleeve 27 is gradually increased, and the vibration amplitude generated after the striking block 29 strikes the arc-shaped protrusion 9 is gradually increased, in such a case, the sound generated after the striking block 29 strikes is also gradually increased, and the gradual increase of the car bell sound can enable a passerby who does not recognize the car bell sound to gradually recognize the big car bell sound, so that the passerby can smoothly avoid a bicycle. When the large car bell still cannot make the passerby aware of, the rider may continue to increase the frequency of toggling the dial plate 5, the wire rope 35 pulls the rectangular cutting sleeve 27 to move to the position close to the bottom of the cutting sleeve sliding groove 25 in the direction away from the impact block 29, the length of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 reaches the maximum, the allowed swing amplitude of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 reaches the maximum, the vibration amplitude generated after the impact block 29 impacts the arc-shaped protrusion 9 reaches the maximum, and in such a case, the sound generated after the impact block 29 impacts is also maximized; passers-by may still not be aware of the largest car ring, or passers-by may not ignore the largest car ring; in this case, the rider is likely to continue to enlarge the dial plate 5, in order to prevent the sound from the striking block 29 from exceeding the limit, and to prevent the rectangular ferrule 27 from being continuously wound when the bottom position of the ferrule sliding groove 25 is reached, the rectangular ferrule 27 is likely to be damaged by the continuous winding of the wire rope 35, so that when the bell sound reaches the maximum, the wire rope 35 is not continuously wound, the internal structure of the bell is protected, the bell sound is maintained to the maximum without breaking the limit, and the greater noise pollution is avoided. In addition, the automobile ring tone is small at first, and can also respond to the environmental call, so that certain noise pollution is reduced.
When the dial plate 5 is not dialed any more, the driving wheel 10 drives the dial plate 5 to move and reset through the swing rod 6 under the reset force of the first scroll spring 20. When the second gear 13 no longer drives the heavy rotation wheel 14, the heavy rotation wheel 14 will gradually stop under the obstruction of the second scroll spring 23 and the arc-shaped protrusion 9; when the heavy rotation wheel 14 stops rotating, the first rotation shaft 61 also stops rotating, and at this time, the restoring force of the second scroll spring 23 is smaller than the limiting friction force of the friction sleeve 60 on the first rotation shaft 61, so that when the second scroll spring 23 makes the heavy rotation wheel 14 ready for reverse rotation, the restoring force of the second scroll spring 23 is not enough to drive the first rotation shaft 61 to rotate through the heavy rotation wheel 14; second scroll spring 23 only rotates heavy duty wheel 14 in the reverse direction; when the second spiral spring 23 is nearly released and the heavy rotation wheel 14 rotates in the reverse direction so that the striking block 29 strikes the last arc-shaped protrusion 9, the rest of the restoring energy of the second spiral spring 23 still makes the striking block 29 pass over the last arc-shaped protrusion 9, so that the second spiral spring 23 can rotate the striking block 29 to restore to the original position through the heavy rotation wheel 14. During the reverse rotation of the heavy rotation wheel 14, the wire rope 35 wound around the first rotation shaft 61 is released; after the heavy rotation wheel 14 stops rotating reversely, the wire rope 35 wound around the second loop is also released, the wire rope 35 on the upper side of the heavy rotation wheel 14 is basically in a tensioned state under the action of gravity of the wire rope 35, and the part of the wire rope 35 located in the ferrule sliding groove 25 is in a relaxed state.
In conclusion, the invention has the main beneficial effects that: the bell of the present invention controls the vibration amplitude of the striking block 29 by using the swing amplitude allowed by the first elastic plate 28 between the striking block 29 and the rectangular clip 27, thereby realizing the control of the sound intensity. In the adjusting mechanism 15, the wire rope 35 moves in a direction away from the impact block 29 by pulling the rectangular cutting sleeve 27, and then the length of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 is adjusted, so that the allowed swing amplitude of the first elastic plate 28 between the impact block 29 and the rectangular cutting sleeve 27 is different, the vibration amplitude of the impact block 29 is also different, and the sound generated after the impact block 29 is impacted is also different. The design that the sound emitted by the impact block 29 is changed from small to big is that passers-by are prevented from hearing a big bell suddenly and frightening one jump to influence the speed of avoiding the bicycles, and the bicycles are prevented from colliding with the passers-by; the gradual increase of the vehicle ring can enable passers who do not realize the small vehicle ring to gradually realize the big vehicle ring, so that the passers can smoothly avoid bicycles. In addition, the automobile ring tone is small at first, and can also respond to the environmental call, so that certain noise pollution is reduced. The invention has simple structure and better use effect.
