TILT HINGE BRACKET OF STEERING COLUMN FOR VEHICLE AND STEERING COLUMN FOR VEHICLE HAVING THE SAME
Disclosed are a tilt hinge bracket of a vehicle steering column and a steering column for a vehicle having the same. The disclosed tilt hinge bracket performs a tilt operation of a steering column without a hinge part as a rotation center during a tilt operation of the steering column, and has a rigid structure that can support the steering column. This can reduce the number of parts and simplify manufacturing and assembling processes.
1 . A tilt hinge bracket of a vehicle steering column, the tilt hinge bracket comprising:
a column plate coupled with a steering column and formed with a column through hole through which the steering column is passed;
a bending plate bent at a predetermined angle with respect to the column plate and formed with a steering shaft through hole through which a steering shaft is passed; and
a mounting plate bent at a predetermined angle with respect to the bending plate and coupled with a vehicle body,
wherein when the steering column is tilt-operated, a bent portion between the column plate and the bending plate or a bent portion between the bending plate and the mounting plate is elastically deformed, thereby forming a tilt angle of the steering column and absorbing impact energy.
2 . The tilt hinge bracket as claimed in claim 1 , wherein in the bent portion between the bending plate and the mounting plate, at least one embossing is formed so as to support elastic deformation.
3 . The tilt hinge bracket as claimed in claim 1 , wherein the bending plate is provided with a reinforcing flange bending at a predetermined angle at one side edge or both side edges of the bending plate so as to support elastic deformation.
4 . The tilt hinge bracket as claimed in claim 1 , wherein the bent portion between the column plate and the bending plate is curvedly formed.
5 . The tilt hinge bracket as claimed in claim 1 , wherein at least one of the column through hole and the steering shaft through hole is provided with a reinforcing flange bending at a predetermined angle at an edge thereof.
6 . A vehicle steering column comprising:
a steering shaft connected to a steering wheel;
a column tube within which the steering shaft is mounted and rotatably coupled;
an upper mounting bracket which is coupled with the column tube and fixes the steering column on a vehicle body; and
a tilt hinge bracket,
wherein the tilt hinge bracket comprises: a column plate coupled with the steering column and formed with a column through hole, in which through the column through hole, the steering column is passed; a bending plate bent at a predetermined angle with respect to the column plate and formed with a steering shaft through hole, in which through the steering shaft through hole, the steering shaft is passed; and a mounting plate bent at a predetermined angle with respect to the bending plate, and coupled with the vehicle body,
wherein when the steering column is tilt-operated, a bent portion between the column plate and the bending plate or a bent portion between the bending plate and the mounting plate is elastically deformed, thereby forming a tilt angle of the steering column and absorbing impact energy.
