Abstract
The utility model relates to a force cell for an electric power-aid vehicle, which is composed of a crank, a force transmitting disk, a chain wheel disk, a press sheet, etc. The utility model is mainly characterized in that the force transmitting disk is fastened on a crank shaft sleeve of a center shaft of a manpower vehicle; the chain wheel disk is sheathed on the crank shaft sleeve; a gasket is arranged between the force transmitting disk and the chain wheel disk; the press sheet is fastened on a crank shaft sleeve at the outer side of the chain wheel disk; the corresponding positions of the same radiuses of the force transmitting disk and the chain wheel disk are provided with spring holes; the inner parts of the holes are provided with springs; the force transmitting disk opposite to the position of the spring holes is provided with a magnetic sheet pair at the corresponding positions of the same radiuses of the force transmitting disk and the chain wheel disk, and hall elements are arranged on the fixed position right towards the magnetic sheet pair. The utility model has an appropriate power-aid relationship, and therefore, the purposes of electricity saving, labor saving, and convenient riding are achieved.
Description
The utility model relates to a kind of force-measuring sensing device of Moped Scooter.
The present electronic rickshaw that uses by the manpower pedal, advances rickshaw by electric power and people's masterpiece driving force or when having electricity.But often need a kind of matching relationship of suitable mutual increasing or decreasing between two kinds of power, that is to say that when firmly pedaling soon, needing to increase have corresponding power-assisted, or manpower needs to reduce corresponding power-assisted when pedaling slowly, or the people does not give power-assisted when not pedaling.And the adapting device of existing two kinds of power can't reach the cooperation ratio of suitable increasing or decreasing, uses operation cumbersome, and cost of manufacture is high high, also is not easy to installation and maintenance.
The deficiency that the purpose of this utility model exists at prior art and provide a kind of simple in structure, cost is low, processing ease, the installation and maintenance force-measuring sensing device of Moped Scooter easily, it can make power-jdriven gear provide the power-assisted of proper ratio when manpower is ridden, and reaches laborsaving, the light effect of riding of power saving.
The purpose of this utility model is achieved in that a kind of force-measuring sensing device of Moped Scooter, it is by driver, controller, battery, formations such as force-measuring sensing device, its force-measuring sensing device is by crank, force transmiting disk, chain sprocket, compositions such as compressing tablet, it is characterized in that the crank axle that force transmiting disk is fastened on the rickshaw axis puts, chain sprocket is enclosed within crank axle and puts, be lined with pad between force transmiting disk and the chain sprocket and be divided into the gap, the crank axle that compressing tablet is fastened on the chain sprocket outside puts, retaining is toward chain sprocket, making chain sprocket put rotation at crank axle is unlikely to again to rock, on the identical correspondence position of force transmiting disk, be provided with the spring eye more than a group or two groups with the chain sprocket radius, the hole is built-in with the spring through compressing in advance, make chain sprocket be subjected to producing relative rotation with force transmiting disk behind certain revolving force, right with the magnetic sheet that the force transmiting disk and the chain sprocket radius same position of spring eye position opposite is provided with more than a group or two groups, a magnetic sheet is fastened on the chain sprocket, another magnetic sheet is fastened on the force transmiting disk, two magnetic sheet staggers on circumference certain distance, two sprocket hole alignment that the magnetic sheet end face is provided with by chain sprocket, right fixed position is provided with Hall element to face magnetic sheet, when chain sprocket during along with the force transmiting disk uniform rotation, right two magnetic sheets of each group magnetic sheet are identical by the mistiming of Hall element end face.Its principle of work: when cyclist's pedal crank, the spring that fastening force transmiting disk on it is crossed by pretension is passed to chain sprocket with power, drives rickshaw by chain again and travels forward; When pedal power hour, force transmiting disk no longer compression spring can be passed to chain sprocket with power, the distance that is fixed on the magnetic sheet on the force transmiting disk this moment and is fixed between the magnetic sheet on the chain sprocket is maximum, and two magnetic sheets are the longest relatively through the mistiming that is fixed on the Hall element under the vehicle frame; When pedal power strengthens, behind the force transmiting disk compression spring power is passed to chain sprocket, at this moment, chain sprocket rotates on the axle sleeve of crank, is fixed on two distances between the magnetic sheet on the dish and dwindles, the mistiming of the magnetic signal of two magnetic sheet process Hall elements shortens relatively, pedal power is big more, and spring is compressed many more, and the distance between the magnetic sheet is more little, mistiming through Hall element is short relatively more, and vice versa; Hall element is imported controller computer with magnetic signal, by the power-assisted size of computer control Moped Scooter driver.Pedal power is big more, and the signal time difference of two magnetic sheets is short relatively more, and the output power of driver is big more; Pedal power is more little, and the magnetic signal mistiming of two magnetic sheets is long relatively more, and the output power of driver is more little, reaches the laborsaving purpose of power saving of Moped Scooter thus.
The utility model is simple in structure, cost is low, convenient, the processing ease of installation maintenance, has suitable power-assisted relation, reaches laborsaving, the light effect of riding of power saving.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
