Embodiment 1
[0120] Embodiment 1. A power-assisted bicycle equipped with multi-magnetic block position unevenly distributed turntable sensors
[0121] Such as figure 1 , 3 , 4, 6,
[0122] 1. The components and structure of the electric bicycle related to the installation of the sensor: the two ends of the central axis 51 of the wheel of the electric bicycle are fixedly connected with the frame 53 of the electric bicycle, and the central axis 51 is covered with a hub 52 with a sleeve, and the hub 52 with a sleeve is on the central axis 51 external rotation, the hub 52 with a cover is fixedly connected with the wheel 54 of the bicycle, and the hub 52 with a cover rotates synchronously with the wheel 54; the battery 55 of the electric bicycle is connected to the motor controller 29, and the motor controller 29 is connected to the motor 30 on the wheel;
[0123] 2. The structure of the sensor and the connection relationship of the components are as follows:
[0124] The sensor includes a ...
Embodiment 2
[0145] Embodiment 2, a power-assisted bicycle with high-density multi-magnetic blocks and unevenly distributed rotary disc sensors
[0146] Such as figure 2 , 3 , 4, 6, one surface of a high-strength aluminum rotating disk 1 with a diameter of 10.0 cm is provided with 40 permanent magnet blocks 2 with a diameter of 0.6 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
[0147] Embodiment 3, a power-assisted bicycle with a specific circuit equipped with a multi-magnetic block position unevenly distributed turntable sensor
[0148] 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;
[0149] [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;
[0150] [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 mod...
