detailed description

The embodiments of the present utility model are described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present utility model. All similar structures and similar changes of the utility model should be included in the protection of the utility model. scope.

As shown in Figures 1-2, a self-propelled suitcase provided by the embodiment of the present invention includes a box body 1, and a front wheel seat 2 is respectively fixed at the two front bottom corners of the box body 1, and the box body 1 Two rear bottom corners of the body 1 are respectively fixed with a rear wheel seat (not shown in the figure), a front wheel 3 is respectively housed on the two front wheel seats 2, and a rear wheel is respectively housed on the two rear wheel seats, and it is characterized in that :

A rotatable steering shaft 7 is placed on the front wheel base 2, and a steering motor 71 for driving the steering shaft 7 to rotate is placed on the front wheel base 2. The steering shaft 7 is integrally vertical, and its vertical position Relative to the front wheel base 2 is fixed, the steering shaft 7 is fixed with a front wheel frame 8, the front wheel frame 8 is equipped with a traveling motor for driving the front wheels to rotate, the stator 62 of the traveling motor is fixed on the front wheel frame, and the front wheel frame 8 is mounted on the front wheel frame. The rotor 61 is coaxially fixed with the front wheel;

The front wheel includes a circular hard tire 31 coaxially fixed on the rotor 61 of the traveling motor, and a circular hub 32, wherein the hub 32 is provided with a plurality of brake grooves 33, and each brake groove 33 surrounds the front wheel. The axis of rotation of the wheel is axisymmetrically arranged at intervals, and the front wheel frame 8 is provided with a pin hole 81 penetrating left and right, and a brake pin 9 that can slide along the axis of rotation of the front wheel and can enter and exit each brake groove 33 is housed in the pin hole 81, and A brake steering gear 91 for driving the brake pin 9 to slide is housed on the front wheel frame 8;

The box body 1 is equipped with a controller 4 for controlling the operation of the steering motor, the traveling motor and the brake steering gear.

The embodiment of the utility model also includes a mobile terminal 5, and the mobile terminal 5 is interconnected with the controller 4 on the box body 1 through wireless communication.

In the embodiment of the utility model, the controller and the mobile terminal are both existing technologies.
