Abstract
The utility model relates to an auxiliary component of an electric bicycle, and particularly to a stepping force sensor device of the electric bicycle. The structure of the stepping force sensor device of the electric bicycle comprises a main power disc which is equipped outside a crank of the electric bicycle. An inner surface and an outer surface of an outer circle of the main power disc are respectively provided with an inner driven disc and an outer driven disc. A spring is provided between the main power disc and the inner driven disc and the outer driven disc. The back parts of the inner driven disc, the outer driven disc and the main power disc are connected with a back sealing cover. A tank body between the back sealing cover and the inner driven disc is internally provided with a sensor circuit, a large coding disc and a small coding disc. Compared with the prior art, the stepping force sensor device of the electric bicycle has the following advantages: more professional design and manufacture, reduced manufacture cost, good mounting manufacturability, high convenience in maintenance, and easy realization for batch production.
Description
Technical field
The utility model relates to a kind of Electrical Bicycle accessory; Specifically provide a kind of Electrical Bicycle pedaling force sensor device; It can measure the firmly size of people when trampling Electrical Bicycle; The data that measure through sensor can realize that motor and manpower trample acting simultaneously, reach the effect that the combination drive Electrical Bicycle is advanced.
Background technology
Prior electric bicycle pedaling force sensor has two types usually.A kind of is middle shaft type, and a kind of is Wheel-type.These two kinds of structures all need to survey the legpower device and are installed on attachments of a bicycle axis or wheel disc, the crank, measure the purpose of legpower with realization.Because bicycle middle shaft, wheel disc, crank specification style are various, requiring of user is different, causes supporting inconvenience, and is difficult to realize standardized batch manufacturing.Moreover owing to receive the restriction of the bicycle part of highly-specialised and typing, the selection space of pedaling force sensor structure is little, and each item technical index also is difficult for the accuracy requirement that reaches high.
Summary of the invention
The utility model is to above problem, a kind of Electrical Bicycle pedaling force sensor device is provided, as a kind of self contained system that measures data on the bicycle part that is used in; Can also connect with the attachments of a bicycle that are associated cleverly simultaneously; This device observing and controlling precision is high, compact conformation, and cost is low; Good manufacturability is fit to specialized batch manufacturing.
The utility model solves the technical scheme that its technical matters adopted:
A kind of Electrical Bicycle pedaling force sensor device; Comprise and be installed on the outer active force dish of Electrical Bicycle crank; Clutch plate and outer clutch plate in the inside and outside two sides of active force dish cylindrical is respectively arranged with; Be provided with spring between said active force dish and the inside and outside clutch plate, the rear of said inside and outside clutch plate and active force dish is connected with the back seal cover cap, is provided with sensor circuit, unitary Item dish and lower Item dish in the casing between said back seal cover cap and the interior clutch plate.
Be respectively arranged with plain bearing between active force dish and back seal cover cap, outer clutch plate and the interior clutch plate.
The center of active force dish is provided with the tapped bore that is connected with bicycle crank, and the cylindrical circumferential position of outer clutch plate is provided with the mounting hole that is connected with the standard bicycle wheel disc.
A kind of Electrical Bicycle pedaling force sensor device of the utility model as supportive body, is installed outer clutch plate and interior clutch plate by the active force dish respectively on the bearing that active force disk center axle both sides are fixed, forming first is the case structure at center with the active force dish.When the active force dish is stressed, torsion is passed to spring, spring passes to the casing of being made up of clutch plate with torsion more then.This device is equipped with two flute profile coding disks (unitary Item dish and lower Item dish) on the left side of casing outer end, fix with driven casing for one, and another and active force dish are fixed.Because stressed spring produces elastic deformation; So can produce certain relative displacement between unitary Item dish and the lower Item dish; The opto-electronic pickup that be installed on the bonnet this moment can read displacement data, is transferred to the controller of Electrical Bicycle after being handled by electronic chip then.
The described active force center hole of the utility model has hickey, bicycle crank that can external all size.
The described outer clutch plate cylindrical of the utility model has connection holes, bicycle wheel disc that can external all size.
Seal cover cap inboard, the described back of the utility model is the case structure composition second layer sealed type case structure at center with the active force dish, is used to install electronic circuit board.The back seal cover cap outside is inlaid with check screw can external bicycle chain bracing frame.
Compared with prior art; A kind of Electrical Bicycle pedaling force sensor device of the utility model; It is fully independently a legpower collection and a processing equipment; And can connect with the bicycle part (for example crank, wheel disc etc.) of standard through external mode, its advantage be manufacture and design more specialized, manufacturing cost reduces, mounting process property is good and easy to maintenance, is easy to realize mass production.
Description of drawings
Fig. 1 is a kind of structural representation of Electrical Bicycle pedaling force sensor device.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment a kind of Electrical Bicycle pedaling force sensor device of the utility model is done further to describe.
Shown in accompanying drawing; A kind of Electrical Bicycle pedaling force sensor device; Comprise and be installed on the outer active force dish 1 of Electrical Bicycle crank; Clutch plate 2 and outer clutch plate 3 in the inside and outside two sides of active force dish 1 cylindrical is respectively arranged with; Be provided with spring 4 between said active force dish 1 and the inside and outside clutch plate, the rear of said inside and outside clutch plate and active force dish 1 is connected with back seal cover cap 5, is provided with sensor circuit 6, unitary Item dish 7 and lower Item dish 8 in the casing between said back seal cover cap 5 and the interior clutch plate 2.
The center of active force dish 1 is provided with the tapped bore 12 that is connected with bicycle crank, and the cylindrical circumferential position of outer clutch plate 3 is provided with the mounting hole 13 that is connected with the standard bicycle wheel disc.
Back seal cover cap 5 is installed on the plain bearing 9 of active force dish 1 inboard.Back seal cover cap 5 the place aheads are connected with interior clutch plate 2.
Back seal cover cap 5 is provided with sensor circuit 6.
After more than assembling is accomplished that sliding damper 14 is fixing with active force dish 1.
After the present embodiment assembling is accomplished, can bicycle crank be installed on the screwed hole of centre 12 of active force dish 1, bicycle wheel disc be fastened on the mounting hole 13 of outer clutch plate 3.Chain guard is supported on the chain guard support and connection hole 15 that is installed in back seal cover cap 5, can be assemblied on the Electrical Bicycle car load and use.
Experiment proof the utility model can with standard wheel disc, the crank connecting link of plurality of specifications, working stability data reliable, that obtain are accurate, can obtain smooth-going comfortable, the brisk labour-saving effect of riding with the Electrical Bicycle of this Data Control manpower and electric power coordinated drive.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection domain of the utility model.
