Problems solved by technology

The rise of self-balancing electric unicycles is about to trigger a new traffic revolution; when riding an existing electric unicycle, the user can control the forward or brake of the unicycle by adjusting the body forward or backward, and when riding at a faster speed When an emergency brake is required during walking, the user will subconsciously lean back the body to brake the unicycle as soon as possible. Excessive force on the motor of the unicycle will cause the instantaneous current to be too large, which will affect the service life of the motor

Embodiment 1

[0016] according to figure 1 and figure 2 As shown, a self-balancing unicycle with a self-adjusting function of the center of gravity described in this embodiment includes a car body 1 and two pedals 3 installed on the mounting columns 2 on both sides of the car body, and the pedals are rotatably connected with A screw mandrel 4, a motor 5 for driving the screw mandrel to rotate is installed in the pedal, and the screw mandrel is connected with the mounting column through a screw drive; the motor is electrically connected with the controller of the wheelbarrow, and when the speed of the wheelbarrow is lower than When the speed of the unicycle is higher than 12 km / h, the motor drives the screw to rotate forward to make the pedals move forward in the direction of travel of the unicycle.

[0017] A notch is formed in the middle of the pedal, and the width of the notch is 20-50mm larger than the width of the mounting column, that is, the range of the front and rear movement of t...

Embodiment 2

[0023] A self-balancing unicycle with a self-adjusting function of the center of gravity described in this embodiment includes a car body 1 and two pedals 3 installed on the mounting columns 2 on both sides of the car body, and a screw rod is rotatably connected to the pedals 4. A motor 5 for driving the screw to rotate is installed in the pedal, and the screw is connected to the mounting column through a screw drive; The switch that is electrically connected to the controller is used to switch the control mode of the controller; when the switch is in the first state, the control mode is the same as in Embodiment 1, that is, when the speed of the wheelbarrow is lower than 5km / h, the motor drives the screw to move forward Rotate to make the pedal move forward in the direction of the unicycle. When the speed of the unicycle is higher than 12km / h, the motor drives the screw to rotate in the opposite direction to make the pedal move backward in the direction of the unicycle; when t...

Embodiment 3

[0026] A self-balancing unicycle with a self-adjusting function of the center of gravity described in this embodiment includes a car body 1 and two pedals 3 installed on the mounting columns 2 on both sides of the car body, and a connecting shaft is rotatably connected to the pedals , the middle part of the connecting shaft passes through the mounting column and is fixedly connected to the mounting column by screws, a linear reciprocating motor is fixedly installed at one end of the pedal, the output shaft of the linear reciprocating motor is coaxially connected with the connecting shaft, and the control of the linear reciprocating motor and the wheelbarrow When the speed of the unicycle is lower than 5km / h, the linear reciprocating motor drives the pedal to move forward in the direction of the unicycle; when the speed of the unicycle is higher than 12km / h, the linear reciprocating motor drives the pedal to move backward in the direction of the unicycle.

Abstract

The invention discloses a self-balance wheelbarrow with a gravity center self-adjusting function. The self-balance wheelbarrow comprises a wheelbarrow body and two pedals mounted on mounting columns on two sides of the wheelbarrow body, wherein each of the pedals is connected with a screw rod in a rotatable manner; a motor for driving the screw rod to rotate is mounted in each pedal; the screw rods are in threaded connection with the mounting columns in a transmission manner; the motors are electrically connected with a controller of the wheelbarrow. When the wheelbarrow is at a higher speed, the motors drive the screw rods to rotate anticlockwise, so that the pedals move backwards relative to the forwarding direction of the wheelbarrow; therefore, when needing to brake the wheelbarrow, a user only needs to lean a little bit back, and the gravity center can be moved to the rear part of the wheelbarrow immediately; timely braking can be realized, and fall over due to great leaning back of the user can be avoided.

Description

[0001] This patent is: [0002] The name of the invention is: a self-balancing unicycle with a self-adjusting function of the center of gravity [0003] The application number is: 2014108271995 [0004] The application date is: 2014.12.25 [0005] divisional application of the patent application. technical field [0006] The invention belongs to the field of unicycle structures, and in particular relates to a self-balancing unicycle with the function of self-adjusting the center of gravity. Background technique [0007] Self-balancing electric unicycle is a means of transportation with electric drive and self-balancing function. With the rapid development of society today, traffic congestion has become a common phenomenon. Electric unicycles replace bicycles and electric vehicles as transportation tools. The rise of self-balancing electric unicycles is about to trigger a new traffic revolution; when riding an existing electric unicycle, the user can control the forward or...
