Embodiment 1
[0118] Embodiment 1. A power-assisted bicycle with unevenly distributed magnetic block position sensors on the motor housing
[0119] Such as figure 1 , 3 , 4, 6,
[0120] 1. Electric bicycle components and structures related to the installation of sensors: including electric bicycles and sensors. The electric bicycle has a motor 30 on its wheels, a motor 30 with a motor housing 1, an electric bicycle has a frame 53, and an electric bicycle battery 55 is connected to the motor control The motor controller 29 is connected to the motor 30 on the wheel.
[0121] 2. The structure of the sensor and the connection relationship of the components are as follows:
[0122] The sensor includes a sensing element, a booster model processor 21, a digital-to-analog converter 27, and an operational amplifier 28 connected in sequence;
[0123] [1] The sensor element is the element that converts the rotational movement of the motor housing 1 into a rectangular wave signal output;
[0124] The sensing el...
Embodiment 2
[0142] Embodiment 2. A power-assisted bicycle with unevenly distributed magnetic block position sensors on the high-density motor shell
[0143] 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 the motor housing 1 with a diameter of 10.0 cm. The magnetic flux of permanent magnet block 2 is 146---279(B·H)max / KJ·m -3 For a certain value in, Hall 3 and each permanent magnet block 2 in the rotating state maintain a distance of 0.2 cm, so that when each permanent magnet block 2 in rotation passes through Hall 3, Hall 3 can generate a corresponding Rectangular wave signal output. The other structure is the same as in Example 1.
Embodiment 3
[0144] Embodiment 3. A power-assisted bicycle with sensors for uneven distribution of magnetic block positions on a motor housing with specific circuits
[0145] Such as figure 1 , 3 , 5, 6, as in Embodiment 1, the sensor includes a sensing element, a booster model processor 21, a digital-to-analog converter 27, and an operational amplifier 28 connected in sequence;
[0146] [1] The Hall 3 in the sensor element selects UGN3075; the other elements and the structure of the element in the sensor element are the same as in embodiment 1;
[0147] [2] The help model processor 21 selects a single-chip computer 31 to complete all functions, and the single-chip 31 selects AT89S52. That is, the AT89S52 single-chip microcomputer 31 completes all functions of the analog-to-digital conversion and the width recognizer 22, the assist starting point selector 23, the magnetic block rotation speed calculator 24, the assist model memory 25 and the assist model calculator 26.
[0148] [3] The digital-to...
