Modular automatic traveling apparatus

Abstract

A modular automatic traveling apparatus includes a seat and an external coupling device mounted onto the seat. The seat includes a moving device to allow the seat to move automatically and an assembling passage which has two ends formed respectively an inlet and a holding orifice. The holding orifice has a detent portion on the perimeter thereof. The external coupling device has an installation portion which is inserted into the assembling passage through the inlet and latched on the detent portion and anchored on the holding orifice, thus is movable automatically with the seat. Users can change the external coupling devices with varying functions such as a vacuum cleaner, odorator and the like to automatically perform different types of tasks through the automatic movement of the seat.

1 . A modular automatic traveling apparatus, comprising:
 a seat which includes a moving device to allow the seat to move automatically and an assembling passage including an inlet and a holding orifice at two ends thereof, and a detent portion located on the perimeter of the holding orifice; and   an external coupling device which includes an installation portion inserted into the assembling passage through the inlet and latched on the detent portion and anchored on the holding orifice to be moved automatically with the seat.   
     
     
         2 . The modular automatic traveling apparatus of  claim 1 , wherein the seat includes an upper case and a lower case coupled with the upper case to hold a holding barrel between them, the holding barrel being hollow to form the assembling passage and including the inlet and the holding orifice at two ends. 
     
     
         3 . The modular automatic traveling apparatus of  claim 2 , wherein the upper case and the lower case include respectively a first opening and a second opening respectively corresponding to the inlet and the holding orifice. 
     
     
         4 . The modular automatic traveling apparatus of  claim 2 , wherein the holding barrel and the installation portion of the external coupling device include respectively a first retaining portion and a second retaining portion to form retaining relationship between them. 
     
     
         5 . The modular automatic traveling apparatus of  claim 4 , wherein the first retaining portion and the second retaining portion are respectively a lug and a groove. 
     
     
         6 . The modular automatic traveling apparatus of  claim 2 , wherein the holding barrel and the lower case include respectively a first coupling portion and a second coupling portion that are coupled with each other. 
     
     
         7 . The modular automatic traveling apparatus of  claim 6 , wherein the first coupling portion and the second coupling portion are respectively a lug and an insertion trough. 
     
     
         8 . The modular automatic traveling apparatus of  claim 1 , wherein the external coupling device is an air humidifier. 
     
     
         9 . The modular automatic traveling apparatus of  claim 1 , wherein the external coupling device is an odorator. 
     
     
         10 . The modular automatic traveling apparatus of  claim 1 , wherein the external coupling device is a vacuum cleaner.
