Problems solved by technology

This needs to improve the traditional speed control handle, but if the improved speed control handle (that is, the speed control handle without reversing switch and can turn the handle to control the positive and negative rotation of the motor) compared with the speed control handle before the improvement The price difference of the speed handle exceeds the price of the reversing switch, which is undoubtedly difficult to promote and use

Embodiment 1

[0061] see Figure 4-8 The forward and reverse speed-regulating handlebar for the electric vehicle shown includes a fixed piece consisting of a handlebar 100 and a handle base 1 fixed on the handlebar 100, and rotates the handle 2 arranged on the handlebar. See Figure 1-3 A boss 22 and an arc-shaped body 24 with an arc-shaped groove 23 are provided on the handle end face 21 axially opposite to the handle seat. The arc-shaped groove is used to place arc-shaped magnetic steel (arc-shaped permanent magnet) 3 . The arc center angle B of the arc permanent magnet is about 100°.

[0062] see Figure 7 , 8 , There is an annular groove 11 on the handle seat opposite to the axial direction of the handle. The axis of the ring groove 11, the axis of the handle, the axis of the handle rod, and the axis of the arc magnetic steel are all coaxial. The bottom surface of the ring groove 11 is provided with a positive limit block 12 , an arc-shaped spring seat 13 , and a Hall sensor 4 .

Embodiment 2

[0070] Embodiment 2 is different from Embodiment 1 in that: when the arc-shaped permanent magnet rotates to different positions relative to the Hall sensor, the output signal of the Hall sensor is a pulse width modulation signal with a duty ratio of 5%-95%. In the reset position, the duty cycle of the hall sensor output signal (reference signal) is about 50%.

[0071] When the electric vehicle needs to move forward, apply counterclockwise torque to the handle and turn the handle counterclockwise. As the angle of rotation of the handle (relative to the reset position) increases, the duty cycle of the output signal of the Hall sensor will change from 50% to 50%. Gradually increase. Until the arc-shaped body 24 contacts the positive limit block 12 in the circumferential direction and the handle cannot continue to rotate counterclockwise, the duty cycle of the output signal of the Hall sensor reaches a maximum of 95%. The controller controls the motor to output a larger torque ac...

Embodiment 3

[0074] see Figure 9 (and refer to Figure 5 , 6 ), the difference between embodiment 3 and embodiment 1 is that there is no reverse limit card 14 in embodiment 1 on the outer wall 15 of the ring groove in embodiment 3, and the handle 2 and slider 5 in embodiment 3 One-piece structure (the slider can be regarded as a part of the handle 2). The turning handle is in the reset position under the joint action of the left turning spring and the right turning spring. When the handle is turned, the handle (and slider) turn together.

Abstract

The technology provides a forward and reverse speed adjustable handle for an electric vehicle. The forward and reverse speed adjustable handle can be turned in both forward and reverse directions to control the forward or reverse turning of an electric vehicle. The forward and reverse speed adjustable handle has the advantages of simple structure, no back-up switch, convenience in operation and high reliability, and the cost is equivalent to that of an ordinary speed regulating handle. The forward and reverse speed adjustable handle comprises a fixed part consisting of a handle stem and a handle seat, and a turning handle, wherein a left turning spring and a right turning spring are arranged between the fixed part and the turning handle; the left turning spring enables the turning handle to counterclockwise turn relative to the handle stem, and the right turning spring enables the turning handle to clockwise turn relative to the handle stem; the turning handle is in a reset position under the combined action of the left turning spring and the right turning spring. When an external force is applied to the turning handle, the turning handle can clockwise or counterclockwise turn from the reset position; a Hall sensor and an arc-shaped permanent magnet are respectively arranged on the turning handle and the fixed part oppositely but without contact; when the turning handle is turned, the Hall sensor moves relative to the arc-shaped permanent magnet, senses different positions of the arc-shaped permanent magnet and outputs relevant different signals.

Description

technical field [0001] The technology relates to a forward and reverse speed regulating handle for an electric vehicle and an electric vehicle power control device including the speed regulating handle, belonging to the technical field of automatic control. Background technique [0002] Traditional electric vehicles (including electric (two-wheel, three-wheel) bicycles and electric (two-wheel, three-wheel) motorcycles) generally include a motor that drives the electric vehicle, a controller that controls the motor, and a regulator that controls the running direction and speed. Speed ​​handlebars and a reverse switch. The speed regulating handle comprises a handle bar, a handle base fixed on the handle bar, and a turning handle arranged on the handle bar. When no external force is applied to the handle, the handle is in the reset position. When an external force is applied to the handlebar, the handlebar can only rotate in one direction (generally counterclockwise) from the...
