Technical Field

The invention relates to the field of electric bicycles, in particular to a battery box lock structure of an electric bicycle.

Background

The lock that used of built-in battery of lower tube in current electric bicycle can be divided into two kinds, and one kind is: the mechanical lock comprises two types: and a spring lock.

In the existing battery which is only in a mechanical lock structure state, the battery is tight due to the fact that the assembling relation of the battery needs to be fixed in the upward opening or side opening state, the battery cannot be jacked up when the battery is taken out, and therefore the battery needs to be taken out forcibly after the lock is opened.

Under the condition of adopting the spring lock, need enlarge the clearance and avoid the false lock risk on the keying structure when opening or inclining and open, but can have the battery to place the back not hard up like this, can let the battery drop under the road surface state of jolting when riding.
