Example Embodiment

[0027] Example 1

[0028] See figure 1 , This embodiment provides an electric bicycle, which includes a central shaft 11, two cranks 12 connected to the central shaft 11, a rear wheel 13, an electric motor 14 for driving the rear wheel 13 to rotate, a Rotation sensor 15, a processing chip 16, a resistance device 17, a speed control handle and a switch.

[0029] One end of the crank 12 is connected to the central shaft 11, and the other end is connected to a foot pedal 121. The crank 12 is driven by the user's legs to rotate, and the rotation of the crank 12 drives the central shaft 11 to rotate. In this embodiment, the central shaft 11 is not directly connected to the rear wheel, that is to say, when the electric bicycle is not powered on, the user turns the crank 12 and cannot make the electric bicycle move forward.

[0030] The rotation sensor 15 includes a first copper ring 151, a second copper ring 152, a wire frame 153, two brushes 154, a current detection device 155 and two ma...

Example Embodiment

[0045] Example 2

[0046] The difference between this embodiment and Embodiment 1 is only:

[0047] See figure 2 The rotation sensor 15 includes two sets of copper rings 151, two wire frames 153, two sets of brushes 154, a current detection device 155 and three sets of magnetic poles 156.

[0048] One end of the crank 12 is connected to the central shaft 11, and the other end is connected to a foot pedal 121. The crank 12 is driven by the user's legs to rotate, and the rotation of the crank 12 drives the central shaft 11 to rotate.

[0049] The wire frames each include two metal rods and a conductor connecting one end of the two metal rods. The four metal rods of the two wire frames are on the same plane and are all perpendicular to the central axis 11, and any two adjacent two The angle between the metal rods is 90 degrees.

[0050] The other ends of the two metal rods are respectively connected to the two copper rings in a group. Each group of brushes corresponds to a group of copp...

Example Embodiment

[0055] Example 3

[0056] The electric bicycle of this embodiment is basically the same as that of Embodiment 1, except that:

[0057] The rotation sensor includes a two-degree-of-freedom gyroscope device, the outer ring of the gyroscope is arranged in the crank, the inner ring of the gyroscope is perpendicular to the axis of the central axis, and the gyroscope is used to detect the According to the rotation speed of the crank, the processing chip is used to control the motor according to the rotation speed to drive the rear wheels to rotate.

Abstract

The invention provides an electric bicycle and a control method thereof. The electric bicycle comprises a center shaft, two cranks connected with the center shaft, a rear wheel and a motor used for driving the rear wheel to rotate. The electric bicycle comprises a rotating sensor and a processing chip. The rotating sensor is used for detecting the rotating speed of the cranks. The processing chip is used for controlling the motor to drive the rear wheel to rotate according to the rotating speed. According to the electric bicycle, the advancing speed of the bicycle is controlled by treading bicycle pedals with feet, the high movement speed can be provided for a user through the electric bicycle, and the electric bicycle can become a bodybuilding tool so that the body health of the user can be facilitated.

Description

technical field [0001] The invention relates to an electric bicycle and a control method thereof. Background technique [0002] An electric bicycle refers to a mechatronic personal vehicle that uses a battery as an auxiliary energy source on the basis of an ordinary bicycle, and is equipped with operating components such as a motor, a controller, a battery, a handlebar, and a display instrument system. In China, the use of electric bicycles is very frequent, and the improvement of electric bicycles is a hot topic. [0003] In the prior art, the forward speed of the electric bicycle is controlled by the speed-regulating handle, and the control method is relatively single, which cannot provide users with more experience in use. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the defect that the control mode of the electric bicycle in the prior art is single and cannot bring better experience to the user, and to p...
