Detachable structure of a chassis

Abstract

A detachable structure of a chassis for use with a light-duty electric vehicle is disclosed. The detachable structure comprises a first framework, a second framework and a fastening device which connects the first framework to the second framework. The fastening device includes a coupling device, a first fastener, and a second fastener. The coupling device is arranged by coupling at least a recess in a transverse bar, whereas the first fastener is configured as a pivoting hook being fastened onto the second fastener which is configured as a transverse rod.

1 . A detachable structure of a chassis, comprising: 
 a first framework;    a second framework;    a fastening device, detachably connecting the first framework to the second framework; wherein the fastening device includes:    a coupling device, including a first coupler disposed for provisionally connecting the first framework and the second framework, the first coupler including a transverse bar and a recess for receiving the transverse bar; whereby the first framework and the second framework completely constitutes the chassis after the transverse bar engages in the recess in position;    a first fastener, having a pivoting handle which is provided with a female unit;    a second fastener, having a male unit, being adapted to be engaged in the female unit of the first fastener after the coupling device connects the first framework with the second framework.    
   
   
       2 . The detachable structure of a chassis as claimed in  claim 1 , wherein the coupling device further comprises a second coupler disposed for provisionally connecting the first framework and the second framework, the second coupler includes a transverse bar and a recess for receiving the transverse bar, whereby the first framework and the second framework completely constitutes the chassis after the transverse bar of each of the first and second couplers engages in the recess of each of first coupler and second couplers in position.  
   
   
       3 . The detachable structure of a chassis as claimed in  claim 2 , wherein the first coupler opposes to the second coupler with respect to the first fastener and second fastener.  
   
   
       4 . The detachable structure of a chassis as claimed in  claim 1 , wherein the first framework has a first end and the second framework has a second end, and the coupling device connects the first end to the second end.  
   
   
       5 . The detachable structure of a chassis as claimed in  claim 4 , wherein the first fastener further comprises a first bracket which has two opposing sidewalls and a fixing plate connecting therebetween, of which the sidewalls and the fixing plate define a space for receiving the pivoting handle which pivots between the sidewalls.  
   
   
       6 . The detachable structure of a chassis as claimed in  claim 5 , wherein the female unit disposed on the pivoting handle is a hook assembly, and the male unit of the second fastener is a transverse rod.  
   
   
       7 . The detachable structure of a chassis as claimed in  claim 6 , wherein the pivoting handle further comprises two pivoting shafts and two opposing sidewalls each having an inner end and an outer end, in which each of the pivoting shafts has two ends with one end thereof being fixed onto the outer end of one of the sidewalls of the pivoting handle, and the other end pivoting onto the respective sidewall of the first bracket.  
   
   
       8 . The detachable structure of a chassis as claimed in  claim 7 , wherein the hook assembly includes two parallel hooks formed on the two sidewalls of the pivoting handle.  
   
   
       9 . The detachable structure of a chassis as claimed in  claim 8 , wherein the second fastener further comprises a second bracket having two opposing sidewalls between which the transverse rod is disposed.  
   
   
       10 . The detachable structure of a chassis as claimed in  claim 5 , wherein the pivoting handle further comprises a handlebar disposed between the sidewalls thereof to facilitate a user's operation.  
   
   
       11 . The detachable structure of a chassis as claimed in  claim 5 , further comprising a seat support vertically disposed on the first end of the first framework, in which the first fastener is disposed on the seat support with the fixing plate of the bracket being mounted on a surface thereof.
