Abstract
A vehicle includes a main body configured to allow a user to ride on the main body, two driving wheels rotatably coupled to the main body, and a controlling wheel part rotatably coupled to the main body to control a direction of the vehicle in which the main body travels at a specific drive velocity by making contact with a ground surface to rotate about a vertical direction in a three-wheel mode. The main body includes a seat part formed to receive the user in a seated position, a steering part configured to obtain an inclination degree to perform steering based on the inclination degree in which the user seated on the seat part is inclined, in the three-wheel mode, and a post configured to connect the steering part with the seat part.
Claims16
A vehicle comprising:
- a main body configured to allow a user to ride on the main body;
- two driving wheels rotatably coupled to the main body;
- and
- a controlling wheel part rotatably coupled to the main body to control a direction of the vehicle, in which the main body travels at a specific drive velocity by making contact with a ground surface to rotate about a vertical axis in a three-wheel mode,
- wherein the main body includes:
- a seat part formed to receive the user in a seated position;
- a steering part configured to obtain an inclination degree of the seat part to perform steering based on the inclination degree in which the user seated on the seat part is inclined, in the three-wheel mode;
- and
- a post configured to connect the steering part with the seat part, and
- wherein the steering part includes;
- a steering shaft member coupled to the post to rotate in connection to the inclination degree of the seat part;
- a steering value obtaining part configured to obtain a steering value based on a degree in which the steering shaft member rotates;
- a steering returning part comprising an elastic member arranged in the vertical direction and a cam provided at a lower end of the elastic member having an outer surface in a curved shape, and the elastic member being coupled to the steering shaft member at an upper end of the elastic member to rotate in connection to rotation of the steering shaft member;
- and
- a steering housing including a guide surface formed inside the steering housing and inclined such that the outer surface of the cam makes contact with the guide surface while sliding.
A vehicle comprising:
- a main body configured to allow a user to ride on the main body;
- two driving wheels rotatably coupled to the main body;
- and
- a controlling wheel part rotatably coupled to the main body to control a direction of the vehicle, in which the main body travels at a specific drive velocity by making contact with a ground surface to rotate about a vertical axis in a three-wheel mode,
- wherein the main body includes:
- a seat part formed to receive the user in a seated position;
- a steering part configured to obtain an inclination degree of the seat part to perform steering based on the inclination degree in which the user seated on the seat part is inclined, in the three-wheel mode;
- and
- a post configured to connect the steering part with the seat part, and
- a steering housing including a guide surface formed inside the steering housing and inclined such that the outer surface of the cam makes contact with the guide surface while sliding,
- wherein a three-wheel gain value determined via a processor, which is used to determine a steering angle allowing the controlling wheel part to rotate as a steering value input by the user multiplied by the three-wheel gain value, is reduced as the drive velocity is increased in the three-wheel mode.
