Electric balancing vehicle

Abstract

The invention discloses an electric balancing vehicle, and belongs to the technical field of walking tools. The electric balancing vehicle comprises a connecting seat, foot pedal devices, rotating mechanisms and a wheel assembly, wherein the foot pedal devices comprise a first foot pedal device and a second foot pedal device symmetrically arranged on both sides of the connecting seat; the number of the rotating mechanism is two the first foot pedal device and the second foot pedal device are connected with the two sides of the connecting seat through the rotating mechanisms. Elastic members are arranged between the rotating mechanisms and the connecting seat so that the tread surfaces of the first pedal device and the second pedal device are kept on the same plane when no external force isexerted on them. As that connecting seat is arranged between the foot pedal devices and the elastic members for pre-balancing are arranged between the rotating mechanisms and the connecting seat, thepressure in the non-rotating direction of a rotating connecting position of the electric balancing vehicle can be effectively dispersed, the coaxiality of the connecting position is ensured, and theself-balancing speed and the success rate of the electric balancing vehicle are improved.

Description

technical field [0001] The invention belongs to the technical field of walking tools, in particular to an electric balance car. Background technique [0002] Electric balance car, also known as somatosensory car and thinking car, its operating principle is mainly based on a basic principle called "dynamic stability", using the sensor inside the pedal device to detect changes in the posture of the pedal device, and Using the servo control system, the precise drive motors are adjusted accordingly to maintain the balance of the system. Common electric balance vehicles are mainly divided into electric balance vehicles controlled by joysticks or two-wheel electric balance vehicles articulated by two pedal seats. Among them, joystick-type electric balance vehicles have longer battery life and are suitable for far The two-wheel electric balance car is being loved by more and more people because of its small size and various ways of playing. [0003] The rotation mechanism of the ...

Problems solved by technology

[0003] The rotation mechanism of the current two-wheel electric balance car is to set a connecting shaft in the middle of the pedal device, and then the left and right pedal devices are mounted on the connecting shaft through the sleeve shaft to realize the relative rotation of the pedal device. When the pedal is installed, it will generate a lot of pressure on the connecting shaft, which makes it difficult to ensure the coaxiality of the sleeve shaft and the connecting shaft, resulting in serious wear of the bearings, affecting the service life of the electric balancing car, and also affecting the stability of the electric balancing car. flexibility

The left and right pedals cannot return to their positions after the external force disappears, so the left and right pedals are not necessarily on the same plane. Therefore, the existing electric balancing vehicles usually need to be started twice to complete self-balancing. When starting, the electric balance car first performs self-balancing through a weak current. The electric balance car senses that the user's foot is on the pedal device through the induction device to perform a second start, and self-balances the other pedal device. Then the user's other foot is on the other pedal device, and the electric balance bike can run normally. Although the setting of two starts is to ensure the safety of the user, it is easy to cause the induction device to malfunction in actual use, resulting in The electric self-balancing scooter will not perform self-balancing or self-balancing failure, or the electric self-balancing scooter vibrates or stops suddenly due to poor contact of the sensing device during the driving process, which affects the user experience and user safety
