Grommet for coupling battery modules

Abstract

A grommet for coupling battery modules includes two coupling portions. A hinge portion connects the coupling portions at first ends thereof. A first hook structure connects the coupling portions at second ends thereof. A second hook structure connects the coupling portions at centers thereof. When the hook structures are hooked, the grommet defines two battery module receiving spaces therein.

1 . A grommet for coupling battery modules, comprising:
 two coupling portions;   a hinge portion connecting the coupling portions at first ends thereof;   a first hook structure, connecting the coupling portions at second ends thereof; and   a second hook structure, connecting the coupling portions at centers thereof;   wherein when the hook structures are hooked, the grommet defines at least two battery module receiving spaces therein.   
   
   
       2 . The grommet for coupling battery modules of  claim 1 , wherein the first ends of the coupling portions comprise notches such that the hinge portion is separated from a remainder of the first ends. 
   
   
       3 . The grommet for coupling battery modules of  claim 1 , wherein the hinge portion comprises two ends and a central portion, wherein the ends are thicker than the central portion. 
   
   
       4 . The grommet for coupling battery modules of  claim 1 , wherein the second hook structure comprises at least one hook protruding from one of the coupling portions, and at least one hole in the other coupling portion, the hole comprising a hook engaging projection therein, configured for the hook to be inserted into the hole and engaged with the hook engaging projection. 
   
   
       5 . The grommet for coupling battery modules of  claim 4 , wherein the hook comprises a reinforcing rib. 
   
   
       6 . The grommet for coupling battery modules of  claim 1 , wherein the first hook structure comprises a hook protruding from one of the coupling portions, and a hook engaging projection on the other coupling portion configured for the hook to be engaged thereon. 
   
   
       7 . The grommet for coupling battery modules of  claim 6 , wherein the hook and the hook engaging projection are tapered.
