MOBILITY AID WITH AN AUTOMATIC TURNING DECELERATION DEVICE

摘要

A mobility aid has a body, a stem, a handle bar, a fixing frame two rear wheels, two motors, a brake-releasing lever, and an automatic turning deceleration device. The automatic turning deceleration device has a fixing base, a fixing unit, a turning sensor, a turning base, a linking unit, and a control module. The turning sensor is rotatably mounted on a side of the fixing unit. The turning base is mounted around the turning sensor. The linking unit is combined on the turning base and abuts the turning sensor. The control module is mounted on a side of the turning base and links between the fixing base and the turning base. Therefore, the automatic turning deceleration device can provide a stable and steady decelerating effect for the mobility aid.

主权项

1. A mobility aid having:
a body; a stem mounted on a front side of the body; a handle bar mounted on a top of the stem; a fixing frame mounted on the stem to fix the stem on the body; two rear wheels mounted rotatably on a rear of the body and respectively located on two sides of the body; at least one motor mounted on the body to drive the rear wheels to rotate; at least one front wheel rotatably connected with the stem; a brake-releasing lever mounted on the handlebar; and an automatic turning deceleration device mounted between a bottom of the stem and the fixing frame, electrically connected with the at least one motor, and comprising
a fixing base mounted on the bottom of the stem;a fixing unit mounted on the fixing frame;a turning sensor rotatably mounted on a side of the fixing unit, electrically connected with the at least one motor, and capable of transmitting a linear decelerating signal to an electronic control system;a turning base mounted around the turning sensor and being rotatable relative to the fixing unit;a linking unit combined with the turning base and abutting the turning sensor; anda control module mounted on a side of the turning base and a bottom of the turning base and linked between the fixing base and the turning base.
