Title: A steering apparatus for an electric-power cart
Inventor: HAHN HOWARD SUNG
IPC: B62B3/00
Filed: 2021-01-15
Abstract: The present invention relates to a steering apparatus for an electric cart, capable of enabling a rotation force of a bar-shaped steering handle (2) controlled by a user while on an electric cart (1) including a foothold provided in the back thereof to switch a direction of a front wheel through a power transmission shaft (3). A helical gear device (22) provided in the bottom of a steering column (21) connected with the steering handle (2) is made to increase a rotation angle, the output of a motor (31) is controlled in response to the increased rotation angle of the steering column, and the output of the motor is increased through a deceleration gear part (32) connected with an output shaft of the motor (31) to enable a steering gear assembly (5) to smoothen rotation for a direction switch of the wheel through the power transmission shaft (3). Therefore, the rotation force of the steering handle is amplified and the rotation angle and the torque are sensed through a sensor to increase the output due to the motor controlled by the control part such that the wheel can be rotated through a stabilizer link connected with the steering gear assembly. Accordingly, since a rotation radius of the electric cart is reduced due to an increase in the rotation angle of the wheel, the direction of the electric cart can be smoothly switched even on a narrow backside road, which can lead to an effect of improving safety and convenience in a steering handle operation by a user.
