Embodiment 1
[0133] Embodiment 1. A power-assisted bicycle with adjustable sensors for magnetic block position and magnetic flux on the flywheel
[0134] Such as figure 1 , 3 , 4, 6,
[0135] 1. The components and structure of the electric bicycle related to the installation of the sensor: including the electric bicycle and the sensor, the rear wheel of the electric bicycle has a flywheel 1, the electric bicycle has a frame 53, the battery 55 on the electric bicycle is connected to the motor controller 29, and the motor controller 29 connect the motor 30 on the wheel;
[0136]2. The structure of the sensor and the connection relationship of the components are as follows:
[0137] [1] The sensing element is an element that converts the rotational motion of the flywheel 1 into a rectangular wave signal output;
[0138] The sensing element is to set 20 permanent magnet blocks 2 with a diameter of 0.6 cm on one surface of the flywheel 1, and the magnetic flux is 146---279 (B·H)max / KJ·m -...
Embodiment 2
[0157] Embodiment 2, a power-assisted bicycle with adjustable sensors for magnetic block position and magnetic flux on the high-density flywheel
[0158] 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 flywheel 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 Different selection values within the range, and the magnetic flux of the adjacent permanent magnet block 2 is not equal, Hall 3 keeps a distance of 0.2 cm from each permanent magnet block 2 in the rotating state, so that each permanent magnet block 2 that is rotating Hall 3, Hall 3 can generate a corresponding rectangular wave signal output. Other structures are the same as in Embodiment 1.
Embodiment 3
[0159] Embodiment 3, a power-assisted bicycle with adjustable sensors for the position of the magnetic block and the magnetic flux on the flywheel with a specific circuit
[0160] 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;
[0161] [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;
[0162] [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 peak recognizer 22 , the power-assisted starting point selector 23 , the magnet speed calculator 24 , the power-assisted model memory 25 and ...
