Abstract
The present invention is a kind of mechanical bell that is used for bicycle.The bell body overhang is directly stirred the bell body with hand and is made it produce vibration on spring.Send the tinkle of bells with the bell clapper percussion that is positioned at the bell intracoelomic cavity during vibration of bell body.Bell clapper is placed on the guide piece, is subjected to do reciprocal relative motion after the percussion of bell body under the guiding of guide piece.The suffered impulsive force of the vibrative direction of the bell physique heart is very little during cycling, can not cause the tinkle of bells.The present invention is simple in structure, and transmission mechanism-free and trigger piece do not exist transmission device to go wrong and the problem that lost efficacy, and productive costs is low, and the tinkle of bells is intensive loud.
Description
The present invention is a kind of mechanical bell that is used for bicycle.The mechanical bell that is used for bicycle at present has the bell of commentaries on classics, pulls bell and change the hammer bell greatly, and they all have transmission device and as the plate handle of driving link.
Chinese patent " stockless inertial bicycle bell " (application number: 87215622) reform, directly pull the rotation of bell body with hand and send the tinkle of bells, need not wheel tooth fan transmission device, surmount from full device and trigger piece to changeing bell.This patent has retaining hammer plate, its essence is cam drive.Under the effect of spring hammerhead jib, reach rotating shaft between bell clapper and retaining hammer plate and increase at the bearing friction resistance.Directly stir bell body rotation with hand, its rotating speed is lower, bell body comparatively fast stop operating (flywheel is contained in the bearing, and size is restricted, and its effect is little) under the friction drag effect.
The objective of the invention is to create a kind of do not have any transmission device, the less bicycle use mechanism bell of friction drag.
The present invention is achieved in that the bell body overhang on spring, directly stirs the bell body with hand and makes it produce vibration.Send the tinkle of bells with the bell clapper percussion that is positioned at the bell intracoelomic cavity during vibration of bell body.If the bell physique heart is 0 point.Speed vector V when 0 of bell body vibration is in balance position
oExpression.As everyone knows, the easiest direction of vibration in the spring stiffness minimum.In other words, V
oThe spring stiffness of direction is little.V
oThe spring stiffness of direction influences the size and the dense degree of the tinkle of bells.Its optimum value is drawn by experiment.And V
oThe spring stiffness of perpendicular direction is got higher value in the scope that structure allows.Bell clapper is placed on the guide piece, is subjected to do reciprocal relative motion after the percussion of bell body under the guiding of guide piece.The sense of motion of bell clapper barycenter is wanted and V during the firm setting in motion of bell clapper
oSubstantially parallel and the basic coincidence of direction.The present invention is installed on the bicycle should make V
oDirection is parallel with the road surface or approaching parallel, and is perpendicular with bicycle straight-line travelling direction or approaching vertical.Facts have proved that during cycling because road surface is smooth inadequately at V
oThe impulsive force that direction causes is very little, and V
oThough suffered impulsive force is bigger, this direction spring stiffness is bigger for perpendicular direction (from bottom to top and by behind the forward direction), and impulsive force produces and makes the component of bell clapper generation relative motion very little, can not cause the tinkle of bells.
If make the bell clapper bell body inwall of when static, getting along well contact the noise that to avoid both to contact and send when riding with the another spring.
The present invention is the same with " stockless inertial bicycle bell " not to have the plate handle, all is directly to stir the bell body with hand, but the former makes the bell body produce vibration, and the latter makes the bell body produce rotation.The mechanical bell of making according to the present invention has following advantage: 1, simple in structure, without any transmission device, not only do not have the gear wheel transmission device, do not have cam drive yet, produces excellent low, do not exist because of transmission device goes wrong to make the mechanical bell inefficacy.2, the friction drag that does not exist spring force to cause.Mechanical efficiency is higher, and the tinkle of bells comparatively dense is loud.
Figure one and figure two are depicted as one embodiment of the present of invention.Figure two is a front view, and figure one is the cutaway view of figure two along the A-A position.
1 is frame among the figure one, and 2 are the arc spring of spring steel band coiling (its transversal surface is an oblong), and 3 is guide piece, and 4 is cylindrical bell clapper, and 5 is the bell body, and 6 is cylindrical spring.2 one ends and the frame 1 of arc spring link, and the other end and guide piece 3 link.Bell clapper 4 is contained in the hole of guide piece 3 (figure one is not shown).One end of cylindrical spring 6 is fixed on the A place of bell clapper 4, and the other end and guide piece 3 link.Bell body 5 and guide piece 3 link (figure one is not shown).0 is the barycenter of bell body 5, V
oVelocity vector when being in balance position for 0 of bell body vibration.Stir the bell body with hand and make it produce vibration, the path of motion that the bell physique heart is 0 is shown in band arrow arc fine line among the figure.Obviously, the sense of motion and the V of bell clapper barycenter during the firm setting in motion of bell clapper 4
oParallel.Bell clapper 4 back and forth knocks the both sides of bell body 5 inwalls and sends the tinkle of bells.
1,2,3,4,5,6 is identical with figure one among the figure two.Can find out that from figure two bell body 5 is tightened in the screw of guide piece 3, bell clapper 4 is contained in the hole of guide piece 3.7 is spheroid.Be fixed together with the bottom of frame 1.8 is top board, and 9 is lower platen.Tighten after the screw (not shown) 8 and 9 with 7 and whole mechanical bell be fixed in the bicycle handle bar.Because 7 is spheroids, mechanical bell can be regulated with respect to the position of handlebar, makes V
oParallel with the road surface or approaching parallel, vertical with bicycle straight-line travelling direction or approaching vertical.The spring steel of coiling arc spring 2, width is more much bigger than thickness, so and V
oThe spring stiffness of perpendicular direction compares V
oDirection is much bigger, and the Shi Buhui that rides causes the tinkle of bells because of impulsive force.
Two ends can equate with the distance of bell body inwall when bell clapper was static, also can be unequal; A distance end far away may no longer knock the inwall of bell body when unequal, and the tinkle of bells frequency reduces half.
If the foregoing description can use equally without cylindrical spring 6, but there are bell clapper and the contacted noise of bell body (change the hammer bell at present and also have this situation, just degree more lightly) when riding.
The foregoing description can be without spheroid 7, and frame 1 and top board 8 are made whole with simplified structure.This mechanical bell must be chosen to be at the position that meets the demands on the handgrip when installing.
The foregoing description can also directly be fixed on frame 1 on bicycle handle bar's screw mandrel without spheroid 7, top board 8 and lower plate 9.
The present invention can also design like this: guide piece does not follow the bell body to vibrate together during the vibration of bell body, and guide piece and pedestal are linked together.
