Embodiment 1
[0126] Embodiment 1. A power-assisted bicycle with an adjustable magnetic block position sensor on the motor housing
[0127] Such as figure 1 , 3 , 4, 6,
[0128] 1. The components and structure of the electric bicycle related to the installation of the sensor: including the electric bicycle and the sensor, the electric bicycle has a motor 30 on the wheel, the motor 30 has a motor casing 1, the electric bicycle has a frame 53, and the battery 55 on the electric bicycle is connected to the motor control Device 29, motor controller 29 connects the motor 30 on the wheel;
[0129] 2. The structure of the sensor and the connection relationship of the components are as follows:
[0130] The sensor includes a sensing element connected in sequence, a boost model processor 21, a digital-to-analog converter 27 and an operational amplifier 28;
[0131] [1] The sensing element is an element that converts the rotational movement of the motor housing 1 into a rectangular wave signal o...
Embodiment 2
[0151] Embodiment 2, a power-assisted bicycle with an adjustable magnetic block position sensor on the high-density motor casing
[0152] Such as figure 2 , 3 , 4, 6, 40 permanent magnet blocks 2 with a diameter of 0.6 cm are arranged on one surface of a motor housing 1 with a diameter of 10.0 cm. The magnetic flux of the permanent magnet block 2 is 146---279 (B·H)max / KJ·m -3 A certain value, Hall 3 keeps a distance of 0.2 cm from each permanent magnet block 2 in the rotating state, so that when each rotating permanent magnet block 2 passes through Hall 3, Hall 3 can generate a corresponding Rectangular wave signal output. Other structures are the same as in Embodiment 1.
Embodiment 3
[0153] Embodiment 3, a power-assisted bicycle with an adjustable magnetic block position sensor on the motor casing with a specific circuit
[0154] Such as figure 1 , 3 , 5, 6, as in embodiment 1, the sensor includes a sensing element connected in sequence, a booster model processor 21, a digital-to-analog converter 27 and an operational amplifier 28;
[0155] [1] The Hall 3 in the sensing element is UGN3075; the structure of other elements and elements in the sensing element is the same as that in Embodiment 1;
[0156] [2] The auxiliary model processor 21 selects the single-chip microcomputer 31 to complete all functions, and the single-chip microcomputer 31 selects AT89S52. That is, the AT89S52 single-chip microcomputer 31 completes all functions of the analog-to-digital conversion and the wave width identifier 22 , the power-assisted starting point selector 23 , the magnet speed calculator 24 , the power-assisted model memory 25 and the power-assisted model calculator ...
