Abstract
The utility model relates to a moment sensor for an electric bicycle chain wheel, mainly solving the problems that the existing sensor is difficult to realize the desired moment, measurement interruption is easily caused and operation is unreliable. The utility model is characterized in that the inner ring and the outer ring of the chain wheel are fixed by bilateral cover plates with grooves; a repositioned cylindrical spring is arranged in the groove of the outer ring of the chain wheel; an inner grating and an outer grating are respectively fixed on the inner ring of the chain wheel and the outer ring of the chain wheel; a protective cover matched with a hinge is arranged at the lateral part of the chain wheel; an infrared photoelectric subassembly is arranged at the inner cavity of the protective cover, and a spring piece and a supporting plate are arranged at the outer cavity of the protective cover. The utility model has the characteristics of the assurance of the desired measurement distance, reliable operation, the realization of the desired moment, stable performance, and water and dust prevention.
Description
The utility model relates to a kind of Electrical Bicycle axis right-hand member that is fixed on, and produces when riding to scrunch moment and to produce the device of electric weight, particularly a kind of Electrical Bicycle sprocket wheel torque sensor through opto-electronic conversion.
Existing Electrical Bicycle all is not provided with the sprocket wheel torque sensor, thereby all be to control the speed of Electrical Bicycle by being located at stepless speed-regulating device on the handgrip, its weak point one is as self-propelled vehicle, and is manually and pin is motionless, inconsistent with the custom of riding of bicycle; The 2nd, storage battery consumption is increased.So Chinese utility model patent (ZL98201683.2) proposes a kind of device of noncontact electrical measurement bicycle pedal moment, thereby can change the manual control mode of Electrical Bicycle.This device is made of axis, right pedal crank, sprocket wheel, photo-transistor, grid, light-emitting diode, ball, frame five-through pipe, axle bowl, end cap and response body, its weak point one is that end cap is fitted on the frame five-through pipe, response body is contained on the axis, both can not guarantee required measuring distance, easily cause to measure and interrupt, it is unreliable to move; The 2nd, response body connects Internal and external cycle by the multi-disc flexure strip and constitutes, and is difficult to realize required moment, so that influence the realization of its function; The 3rd, the split assembling can't seal, and water, dust are entered easily, influences the survey precision of electro-optical tubes.
The purpose of this utility model is exactly to provide a kind of at above-mentioned weak point and can guarantee required measuring distance, realize required moment, the Electrical Bicycle sprocket wheel torque sensor of exclusion seal.
Technical solution of the present utility model is: a kind of Electrical Bicycle sprocket wheel torque sensor, comprise inside and outside grating, the photoelectricity subassembly has the inside and outside circle of the sprocket wheel that relatively rotates stop gear, it is characterized in that: described sprocket wheel inner ring is fixed on the right crank assemblies; The inside and outside circle of sprocket wheel is fixed together through rivet by the cover plate of the trough of belt of its both sides; Be provided with the cylindrical spring that resets in the draw-in groove of sprocket wheel outer ring.Inside and outside grating is separately fixed on the inside and outside circle of sprocket wheel, and its sidepiece is provided with the guard shield of hinge connection with it.Described photoelectricity subassembly is the infrared electro subassembly, is arranged on shroud interior.Flexible of guard shield peripheral hardware and can be fixed in back plate on the frame five-through pipe.
Can be arranged with three groups or four groups of cylindrical springs that reset on the sprocket wheel outer ring described in the utility model technical solution.
The utility model is because the inside and outside circle of its sprocket wheel, cover plate, inside and outside grating, guard shield forms cross-linked structure, thereby can overall fixed on the standard axis, the loading and unloading debugging is convenient on the one hand, can guarantee required measuring distance on the other hand, and is reliable.Because adopt the cylindrical spring that resets, thereby can realize required moment, and stable performance, the endurance life-span is long.Owing between back plate and guard shield, be provided with elastic component, thereby when shape position error appears in the relative frame five-through pipe of right crank, can guarantee that all the guard shield end face presses on the cover board, realize the contact of floating, play the effect that dustproof and waterproof immerses internal organ.After adopting the utility model, the size of the size of the power of motor of Electrical Bicycle pedal moment when riding is controlled, thereby consistent with the custom of riding of bicycle, bodybuilding and entertainment, and can prolong the service life of storage battery and charge after ride the time.The utility model has overcome the deficiencies in the prior art part, thereby has reached the purpose of this utility model.
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in the figure.Sprocket wheel inner ring 6 is fixed on the right crank assemblies 7.Sprocket wheel outer ring 1 and sprocket wheel inner ring 6 are fixed together through rivet 4 by the cover plate 5 of both sides, and inside and outside grating 13,18 is captiveed joint with the inside and outside circle 6,1 of sprocket wheel respectively, and form chain wheel assembly 8.Be equipped with the groove of evagination on the cover plate 5, and evenly be provided with three or four through hole draw-in grooves on the cooresponding sprocket wheel of this groove outer ring 1, be provided with the cylindrical spring 2 that resets in this through hole draw-in groove, be with lining 3 on the rivet 4, be in the front end of cylindrical spring 2.Infrared electro subassembly 16 guard shield 17 inner chambers of packing into form cover assembly 9.Guard shield 17 matches with inside and outside grating 13,18, and guard shield 17 outsides are installed on the outside of outer grating 18, and contact with cover plate 5; Inner edge is provided with hook, captives joint with the stay hook on interior grating 13 inner edges.Be respectively equipped with the projection and the groove of cooperation on the inside and outside circle 6,1 of sprocket wheel, the width of groove forms stop gear in relative rotation greater than the width of projection.8, the 9 mutual interlocks of two assemblies also do not separate through rotatablely moving.Flexible 10 of guard shield 17 peripheral hardware and back plate 14, and by 11 unsteady connections of rest pin, the support shield termination is adjacent to cover plate 5 but disjunctor floats, and plays the better seal effect.Back plate 14 is fastenedly connected with frame five-through pipe 12, and frame five-through pipe 12 is former body part with axle bowl 15.When riding, right crank assemblies 7 is subjected to spacing mechanism controls moment size with sprocket wheel outer ring 1, and chain wheel assembly 8 produces relative rotary motion with cover assembly 9, and the infrared electro subassembly that parallels to the axis is finished and detected and carry cooresponding electric signal.Electrical Bicycle electric signal control motor is in view of the above done corresponding power output, pedals soon, and output is big, pedals slowly, export for a short time, does not pedal and then stops output, is accustomed in full accord with riding of ordinary bicycle.
