Abstract

The present disclosure relates to a smart belt including: a belt body; a belt buckle provided on the belt body; a GPS positioning mechanism for generating a traveling direction; and a rotatable direction indication mechanism for indicating the traveling direction; a drive mechanism for driving the direction indication mechanism to rotate to indicate the traveling direction according to the traveling direction given by the GPS positioning mechanism; and a light source used to project the traveling direction indicated by the direction indication mechanism onto the road surface. The beneficial effects of the present disclosure are: users' hands can be freed and the portability and convenience of navigation usage can be improved.

First claim

The invention claimed is:

1. A smart belt comprising:
a belt body; and
a belt buckle, which is provided on the belt body;
wherein the smart belt further comprises:
a GPS positioning mechanism for generating a travel direction;
a rotatable direction indication mechanism for indicating the traveling direction, which is provided on the belt buckle;
a drive mechanism for driving the direction indication mechanism to rotate to indicate the traveling direction according to the traveling direction given by the GPS positioning mechanism;
a light source for projecting the traveling direction indicated by the direction indication mechanism onto a road surface.

2. The smart belt according to claim 1 , wherein the light source is disposed on a side of the direction indication mechanism close to the belt buckle.

3. The smart belt according to claim 2 , wherein the light source is disposed at a position higher than a position of the direction indication mechanism in a direction perpendicular to the road surface.

4. The smart belt according to claim 1 , wherein the direction indication mechanism comprises:
a support structure having a cylindrical shape and its axial direction perpendicular to a main surface of the belt buckle, and having a receiving space in its central area;
a direction pointer which is located in the receiving space.

5. The smart belt according to claim 4 , wherein the direction indication mechanism further comprises:
a fixed dial having a scale, wherein the fixed dial is stacked on a side of the support structure close to the belt buckle, and the fixed dial is coaxially arranged with the support structure.

6. The smart belt according to claim 5 , wherein there are 4 main scales and 4, 8 or 12 sub scales provided uniformly on the fixed dial.

7. The smart belt according to claim 5 , wherein the direction pointer comprises a fixed fulcrum pivoted on the support structure and a free end rotatable about the fixed fulcrum, and the fixed fulcrum is located at an axis of the support structure.

8. The smart belt according to claim 1 , wherein the drive mechanism comprises:
a link gear capable of rotating the direction indication mechanism;
a drive gear capable of driving the link gear to rotate;
a motor that can control the drive gear to rotate; and
a transmission part connecting the motor and the drive gear.

9. The smart belt according to claim 1 , wherein the smart belt further comprises a voice output mechanism that can output the traveling direction by voice.

10. The smart belt according to claim 9 , further comprising a function key provided on the belt buckle, for controlling on/off of the direction indication mechanism, the light source and/or the voice output mechanism.
