ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a locking device of tailgate for vehicle, more particularly to a locking device of tailgate for vehicle which can simultaneously control the locking of a tailgate latch and the locking of a glass latch.
BACKGROUND OF THE INVENTION
Generally, a locking device of a tailgate for vehicle locks or unlocks the tailgate latch according to the state that a key lock is locked or unlocked, and the tailgate latch is locked when the key lock is unlocked.
FIG. 5
is a schematic diagram of the state that the prior tailgate-locking device is mounted on a vehicle. The prior tailgate-locking device can unlock a tailgate latch
10
when a key lock
80
is unlocked, and the tailgate
99
can be opened by hand.
And when the key lock
80
is locked, the tailgate latch
10
is locked by the mechanical operation of the locking device mounted on a base plate
100
and the tailgate
99
cannot be unlocked.
Meanwhile, recently a vehicle has been produced where the glass
98
of the tailgate
99
can be opened. This vehicle requires that the glass
98
is not opened when the tailgate gate
99
is locked.
Generally the prior tailgate-locking device, however, can control only locking and unlocking of the tailgate latch
10
and cannot control the locking and unlocking of the glass
98
.
Therefore, in a vehicle that the glass of the tailgate can be opened, the conventional tailgate-locking device cannot control the locking and unlocking of the glass in the tailgate.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a locking device of tailgate for a vehicle, which can simultaneously control the locking of the tailgate latch and the locking of the glass latch:
The present invention comprises a base plate having three mounting portions, a connecting flange and two limit flanges; a locking lever pivotally mounted on the base plate and connected with a key lock through a key locking rod and a tailgate latch through a tailgate latch locking rod respectively; an open lever pivotally mounted on the base plate and connected with a glass latch through a glass locking rod and a glass open handle, and being operated by the glass open handle; and the locking lever having a stopper for limiting the operation of the open lever, and the open lever having a stopper for limiting the operation of the locking lever.
A protrusion portion is provided on the base plate on which the open lever is pivotally connected so as to reduce the friction force that is occurred when the open lever is pivoted.
A protrusion portion is also provided on the base plate on which the locking lever is pivotally connected so as to reduce the friction force that is occurred when the locking lever is pivoted.
The protrusion of the locking lever is contacted with the protrusion of the open lever, when the tailgate is unlocked so that the glass latch can be unlocked.
Therefore, the locking device in accordance with the present invention can simultaneously control the locking of the tailgate latch and the locking of the glass latch when locking the tailgate with the key lock.
