Description
Technical field
The invention belongs to the checkout equipment in detection technique field, particularly electric bicycle, more specifically, relate to the checkout equipment that detects electric bicycle driving force ratio.
Background technology
Electric bicycle is to be the energy with the accumulator, and the bicycle of power-assist power is provided.In recent years, a lot of cities have been eliminated motorcycle and are provided the power assist vehicle of power with fuel engines, and electric bicycle becomes the new lover who rides instead of walk in the city because of its light laborsaving, environmental protection, and its recoverable amount is increasing, and manufacturer is also more and more.The consumer always wishes that electric bicycle is laborsaving more good more, and The faster the better for speed, and considers from the angle of traffic safety, and is obviously really not so.Because electric bicycle itself is a kind of light bicycle, its body frame structure for automotive, clamping device all design by low speed, low load, pursue high speed, large driving force simply, will cause potential safety hazard.So, be necessary the speed and the driving force of electric bicycle are made restriction.
Existing traffic law and industry standard have been done qualification to the top speed of electric bicycle, but when this speed is actually separately by motor-driven, the top speed that electric bicycle can reach on level road, existing detection means also can only be measured this speed.This index is not considered the situation that manpower and motor-driven power act on simultaneously, does not consider the influence of different condition of road surface to the speed of a motor vehicle yet, and is comprehensive not to the utmost.Such electric bicycle, can be short of power under some situation when abrupt slope (as above) can surpass speed limit and some situation is next.
For addressing this problem, the someone has proposed a kind of new standard, promptly limits the driving force of motor, specifically, is according to the different speed of a motor vehicle, limits the ratio of motor-driven power and manpower.When the speed of a motor vehicle is low, can rely on the driving force of motor morely; When the speed of a motor vehicle is higher, will reduce the driving force of motor; After the speed of a motor vehicle reaches a certain numerical value, will rely on manpower fully.This scheme makes the bicyclist naturally and understandably not define top speed (being the top speed that bicyclist's manpower can reach) with motor as the major impetus source; When road conditions are relatively poor, then allow motor that more power is provided simultaneously, embodied the thinking of motor preferably as " auxiliary power ".
After adopting this thinking, the control mode of electric bicycle also will change, no longer by manual governing the output power of control motor, but the size by manpower on the sensor senses electric bicycle pedal, output power according to the program decision motor that presets, rationally adjust the ratio of motor-driven power and manpower, realize the man-machine vehicle operating of making a concerted effort to drive.Like this, the bicyclist need not use the hand control motor, and two hands all can be used for the control of direction and brake, has further guaranteed traffic safety.And people and machine to electric bicycle cooperation acting, make motor can not be in big current work state for a long time with certain proportion, help protecting motor, prolong mileages of continuation.Therefore, this vehicle form is expected to replace traditional electric bicycle, becomes main product, has the people to propose concrete ratio standard, when speed of a motor vehicle v when 15km/h is following, the ratio a of motor-driven power and manpower is 1; When speed of a motor vehicle v when the above 24km/h of 15km/h is following, ratio a is 1-(v-15)/9; When the speed of a motor vehicle when 24km/h is above, need not replenish manpower with motor, promptly ratio a is 0.
From above background introduction as can be seen, realize the electric bicycle of this form, key is to detect accurately and effectively driving force ratio, and in the prior art to the detection of dispatching from the factory of electric bicycle, only limit to indexs such as startability, max. speed, grade climbing performance, braking ability, lack detection method, more lack relevant detection equipment motor-driven force rate value.The applicant once applied for a kind of analoging detecting device, it comprises test stage body and switch board, be electrically connected between test stage body and the switch board and have data line to connect simultaneously, switch board has voltage, direct supply that electric current is adjustable, can be used as the working power of detected object; The test stage body is provided with clamping device, but the engaged wheel of fixed test object; The test stage body on and be provided with charger, can simulate the loaded weight of human body to detected object; Also be provided with the road conditions analogue means of double wheel hub on the test stage body, described double wheel hub one in front and one in back is provided with, and is installed in rotation on the test stage body with its axle center respectively, thereby the driving wheel of detected object is clipped between two wheel hubs; On one of them wheel hub position/displacement transducer is housed, on another wheel hub damp generator is housed.This pick-up unit can carry out the detection of some conventional indexs, but also can't detect driving force ratio.
