Packaging structure for electronic device

Abstract

A packaging structure for an electronic device. The packaging structure comprises a main body and an auxiliary element. The main body comprises a first side, a second side opposite to the first side, a third side and a bottom adjacent to the third side. The auxiliary element is disposed on the main body. The main body moves along the surface with the auxiliary element contacting the surface.

1 . A packaging structure for an electronic device, comprising
 a main body comprising a first side, a second side facing the first side, a third side and a bottom adjacent to the third side;   an auxiliary element disposed on the main body, wherein the main body moves along a surface by contacting the surface with the auxiliary element.   
   
   
       2 . The packaging structure as claimed in  claim 1 , wherein the auxiliary element comprises at least one pad body disposed on the bottom, whereby the main body moves along the surface by contacting the surface with the auxiliary element. 
   
   
       3 . The packaging structure as claimed in  claim 2 , wherein the auxiliary element further comprises a cord with one end extending through the pad body and fixed to the first side and the other end detachably joined to the second side to fix the pad body on the bottom. 
   
   
       4 . The packaging structure as claimed in  claim 3 , wherein the pad body is a cylinder rotatably disposed on the bottom. 
   
   
       5 . The packaging structure as claimed in  claim 1 , wherein the auxiliary element comprises at least one pad body disposed at the junction of the third side and the bottom, whereby the main body moves along the surface by contacting the surface with the auxiliary element. 
   
   
       6 . The packaging structure as claimed in  claim 5 , wherein the pad body is a cylinder. 
   
   
       7 . The packaging structure as claimed in  claim 1 , wherein the auxiliary element comprises at least one sliding member disposed at the junction of the third side and the bottom, whereby the main body moves along the surface by contacting the surface with the auxiliary element. 
   
   
       8 . The packaging structure as claimed in  claim 7 , wherein the sliding member is a metal sheet. 
   
   
       9 . A packaging box, comprising:
 a main body comprising a handle surface and an auxiliary element surface;   a handle disposed on the handle surface;   an auxiliary element disposed on the auxiliary element surface, wherein when the handle is pulled up, the auxiliary element surface is nearest to the surface of the main body, and the auxiliary element bears the weight of the packaging box and moves relative to the surface.   
   
   
       10 . The packaging box as claimed in  claim 9 , wherein the auxiliary element comprises a ring member having a hollow portion and a cord comprising a first end and a second end both connected to the main body, the cord extends through the hollow portion to secure the ring member to the auxiliary element surface. 
   
   
       11 . The packaging box as claimed in  claim 10 , wherein the ring element further has a gap allowing the cord to enter the hollow portion. 
   
   
       12 . The packaging box as claimed in  claim 10 , wherein the cord is rigid to bear the weight of the main body, whereby the ring member is maintained a predetermined distance from the main body and rotates along the surface. 
   
   
       13 . The packaging box as claimed in  claim 9 , wherein the auxiliary element surface is at the junction of a bottom and a side of the main body, the auxiliary element surface is a curved surface, and the auxiliary element is a curved sliding element, whereby when the packaging box is picked up at different angles, the auxiliary sliding element keeps substantially the same contacting area and slides along the surface. 
   
   
       14 . The packaging box as claimed in  claim 9 , wherein the ring member is a cylinder.
