Light-emitting Building Block Having Electricity Connection Unit

Abstract

A building block includes a hollow brick and a plurality of electricity connection units. The brick has a light member mounted on a circuit board. Each electricity connection unit is connected with the circuit board, and includes a hollow tubular member having two half tubes, two conducting members received in the tubular member, a compression spring received in the tubular member and an annular electricity connection member sleeved on a top end of the tubular member. A first wire connects with the circuit board and the compression spring. A second wire connects with the circuit board and the annular electricity connection member. The second wire has a bending portion disposed by a bottom end of the tubular member. Thus, after multiple building blocks are assembled, the electricity connection units form a circuit to illuminate the light member.

 a hollow tubular member having two half tubes connected with each other, the tubular member having a top end and a bottom end, each of the top end and the bottom end of the tubular member having a through hole, the top end and the bottom end of the tubular member being respectively received in the stud and the tube of the brick, one of the half tubes having a male engaging member and another half tube having a female engaging member, after the male engaging member being engaged with the female engaging member, the two half tubes being assembled to form the tubular member; 
 two conducting members respectively received in the top end and the bottom end of the tubular member, and extended through the through hole and projected out of the tubular member, portions of the conducting members projected out of the top end and bottom end of the tubular member being respectively received in the stud and the tube; 
 a compression spring received in the tubular member, both ends of the compression spring being respectively pressed against the two conducting member, the compression spring having a first wire which passes through the tubular member and connects with the control circuit board; and 
 an annular electricity connection member sleeved on the top end of the tubular member and received in an inside of the stud, the annular electricity connection member having a second wire extending along a side wall of the tubular member and passing through the control circuit board, the second wire having a bending portion disposed by an inner surface of the tube, the second wire connected with the control circuit board. 
   
     
     
         2 . The building block as claimed in  claim 1 , wherein the tubular member comprises a folding piece disposed between and connected with side edges of the two half tubes, the male engaging member and the female engaging member are respectively disposed at side edges opposite to the side edges connecting with the folding piece, after the folding piece is folded, the male engaging member is engaged with the female engaging member to assemble the two half tubes together. 
     
     
         3 . The building block as claimed in  claim 1 , wherein the tubular member comprises a side opening disposed at a side wall thereof to allow the first wire to pass through. 
     
     
         4 . The building block as claimed in  claim 1 , wherein the conducting member comprises a head and a tail, the head has a diameter larger than that of the through hole of the tubular member and is received in the tubular member, the tail has a diameter smaller than that of the through hole of the tubular member and extends through the through hole and projects out of the tubular member. 
     
     
         5 . The building block as claimed in  claim 1 , wherein the brick comprises a bottom base and a top cover mounted on the bottom base, the studs and the tubes are respectively disposed on the top cover and the bottom base. 
     
     
         6 . An electricity connection unit for a light-emitting building block, the electricity connection unit comprising:
 a hollow tubular member having two half tubes connected with each other, the tubular member having a top end and a bottom end, each of the top end and the bottom end of the tubular member having a through hole, one of the half tubes having a male engaging member and another half tube having a female engaging member, after the male engaging member being engaged with the female engaging member, the two half tubes being assembled to form the tubular member;   two conducting members respectively received in the top end and the bottom end of the tubular member, and extended through the through hole and projected out of the tubular member;   a compression spring received in the tubular member, both ends of the compression spring being respectively pressed against the two conducting member, the compression spring having a first wire which passes through the tubular member; and   an annular electricity connection member sleeved on the top end of the tubular member and received in an inside of the stud, the annular electricity connection member having a second wire extending along a side wall of the tubular member, the second wire having a bending portion disposed by the bottom end of the tubular member.   
     
     
         7 . The unit as claimed in  claim 6 , wherein the tubular member comprises a folding piece disposed between and connected with side edges of the two half tubes, the male engaging member and the female engaging member are respectively disposed at side edges opposite to the side edges connecting with the folding piece, after the folding piece is folded, the male engaging member is engaged with the female engaging member to assemble the two half tubes together. 
     
     
         8 . The unit as claimed in  claim 6 , wherein the tubular member comprises a side opening disposed at a side wall thereof to allow the first wire to pass through. 
     
     
         9 . The unit as claimed in  claim 6 , wherein the conducting member comprises a head and a tail, the head has a diameter larger than that of the through hole of the tubular member and is received in the tubular member, the tail has a diameter smaller than that of the through hole of the tubular member and extends through the through hole and projects out of the tubular member.
