Steering roll connector for a vehicle
The present invention relates to a steering roll connector for a vehicle. The steering roll connector includes a roll stator, a roll rotor, a roller plate, and a locking unit. The roll stator is fixed to a vehicle. The roll rotor is coaxial to the stator, is rotatable relative to the stator, and includes a rotor connector provided with a steering wheel connector. The roller plate is rotatably disposed between the roll stator and the roll rotor. When a steering wheel shaft of the vehicle is not installed on the steering roll connector, the locking unit maintains the steering roll connector in a neutral position. When the steering wheel shaft is installed on the steering roll connector, the locking unit enables the roll rotor to rotate relative to the roll stator.
1. A steering roll connector for a vehicle comprising:
a roll stator fixed to the vehicle;
a roll rotor arranged coaxially and rotatably with respect to the roll stator, the roll rotor including a rotor connector provided with a steering wheel connector;
a roller plate rotatably disposed between the roll stator and the roll rotor; and
a locking unit configured to maintain the steering roll connector in a neutral position when a steering wheel shaft of the vehicle is not mounted on the steering roll connector, and enable the roll rotor to be rotated relative to the roll stator when the steering wheel shaft of the vehicle is mounted on the steering roll connector,
wherein the locking unit comprises:
a locking part disposed at a rotor locking mounting part disposed at a roll rotor side;
a stator locking mounting part formed at the roll stator to correspond to the position of the locking part; and
a roller plate locking mounting part formed at the roller plate,
wherein the locking part comprises:
a locking block movably disposed at the rotor locking mounting part;
a locking elastic part configured to abut at one end thereof against the rotor locking mounting part and abut at the other end thereof against the locking block to elastically support the locking block; and
a locking hinge part brought into close contact at one end thereof with the lock block and brought into close contact at the other end thereof with a steering wheel shaft side of the vehicle in such a manner as to be disposed at the other end thereof pivotally at the roll rotor,
wherein,
when a steering wheel shaft of the vehicle is not mounted on the steering roll connector, the roller plate locking mounting part and the stator locking mounting part are disposed to correspond to each other and forms a predetermined space together to enable the locking block to be inserted and accommodated therein when a steering wheel shaft of the vehicle is not mounted on the steering roll connector, and
when the steering wheel shaft of the vehicle is mounted on the steering roll connector, the locking hinge part pivots to move the locking block out of the predetermined space.
2. The steering roll connector for a vehicle according to claim 1 , wherein the locking block comprises:
a locking block body movably disposed at the rotor locking mounting part;
an elastic part-mounting part disposed at one end of the locking block body to support the locking elastic part;
a hinge contact part formed at the locking block body to come into close contact with the locking hinge part; and
a movable part formed at the other end of the locking block body to be inserted into and be moved out of the predetermined space.
3. The steering roll connector for a vehicle according to claim 1 , wherein the locking hinge part comprises:
a locking hinge body disposed at the rotor locking mounting part so as to be pivotally rotated about a locking hinge center part;
a locking block contact part formed at one end of the locking hinge body so as to come into close contact with the locking block; and
a movable part formed at the other end of the locking hinge body so as to so as to come into close contact with the steering wheel shaft of the vehicle.
4. The steering roll connector for a vehicle according to claim 3 , wherein the roll rotor comprises a locking stopper through-opening for allowing the locking hinge body to pass therethrough, and
the locking hinge center part is mounted pivotally in the locking stopper through-opening.
5. The steering roll connector for a vehicle according to claim 4 , wherein the roll rotor further comprises a locking stopper formed on the outer surface of the locking stopper through-opening so as to prevent the locking hinge part from escaping from the locking stopper through-opening.
6. The steering roll connector for a vehicle according to claim 3 , wherein the locking block contact part is formed in a “ ”-shape.
7. The steering roll connector for a vehicle according to claim 6 , wherein the locking block comprises:
a locking block body movably disposed at the rotor locking mounting part;
an elastic part-mounting part disposed at one end of the locking block body to support the locking elastic part;
a hinge contact part formed at the locking block body to come into close contact with the locking hinge part; and
a movable part formed at the other end of the locking block body to be insertable into and be movable out of the predetermined space, and
wherein the locking block contact part can be accommodated in the hinge contact part.
