Bean Charlie's dropped in carriage (7)

I believe the answer is:

haricot

I'm a little stuck... Click here to teach me more about this clue!

'bean' is the definition.
(haricot is a type of bean)

I cannot understand how the remainder of the clue works.

(Other definitions for haricot that I've seen before include "kind of ragout" , "French bean" , "Type of bean in a chariot" , "Vegetable" , "Variety of bean" .)
