1 to 6, a hinge unit for a vehicle console armrest according to an embodiment of the present invention includes an upper bracket 100, a lower bracket 200, and an auxiliary bracket 300. In this case, the hinge unit of the console armrest for a vehicle according to the embodiment of the present invention may further comprise a spring 400.

The upper bracket 100 is fixed to an armrest (not shown), and upper and lower hinge holes 110 through which the hinge shaft 10 is passed are symmetrically disposed on both sides of the upper bracket 100. Upper hinge holes 110, Shaped first guide holes 120 are provided symmetrically with respect to each other.

In this case, the first guide hole 120 guides the rotation of the upper bracket 100 fixedly coupled to the lower bracket 200 when the user rotates relative to the lower bracket 200, as the user opens the armrest Role. That is, the auxiliary bracket 300, which will be described later, guides the rotary motion while relatively moving along the inner side wall of the first guide hole 120.

At this time, the inner side wall of the first guide hole 120 is provided with a completely closed prescribed inner side wall (see FIG. 4) in which the auxiliary bracket 300 hits the armrest or the fully closed state of the upper bracket 100 The outer side inner wall 120c, and the inner side wall 120d, which define the fully opened state of the armrest or the upper bracket 100 by colliding with the auxiliary bracket 300, ≪ / RTI >

The clip releasing part 121 is formed on the outer side inner wall 120c or the auxiliary bracket 300 is held on the outer side inner wall 120c and the inner side wall 120d by a design change This is based on a technical idea within the same range.

On the other hand, both ends of the inner wall of the first guide hole 120 preferably meet the auxiliary bracket 300 to define the fully opened state of the armrest and the fully closed state of the armrest. That is, as described above, the inner wall 120a and the auxiliary bracket 300, which are in contact with the auxiliary bracket 300 and define the armrest or the fully closed state of the upper bracket 100, collide with the auxiliary bracket 300, The fully open prescribed inner side wall 120b defining the fully opened state of the bracket 100 determines the rotation limit of the armrest.

At this time, when the auxiliary bracket 300 is positioned at both ends of the inner wall of the first guide hole 120, the sectional centers c1 and c2 of the auxiliary bracket 300 are positioned at 90 degrees around the central axis of the hinge shaft 10 It is preferable to form the first central angle [theta] 1.

In other words, since it is a general construction that the armrest is opened in a parallel state and a vertical state, the sectional center c1 when the auxiliary bracket 300 hits the side wall 120a in the full closing specification, Sectional center c2 of the center of the hinge shaft 10 when hit against the side wall 120b forms a first central angle? 1 of 90 degrees with the center of the hinge shaft 10 or the center of the upper hinge hole 110.

On the other hand, if the first guide hole 120 is formed so as to have a smaller hole area from the inner wall 120a to the completely closed inner wall 120b, the overlapped portion of the auxiliary bracket 300 described later increases So that the opening speed due to the opening of the armrest is delayed, thereby improving the operational feeling.

On the other hand, the spring fixing holes 130 may be provided symmetrically on both sides of the upper bracket 100. This is a space in which both ends of a spring 400 to be described later are fitted.

The arc-shaped second guide holes 230 may be symmetrically arranged on both sides of the lower bracket 200 about the lower hinge holes 210. This is to form a space for guiding the movement of the spring 400 having the both ends inserted into the spring fixing hole 130 of the upper bracket 100.

5, the inner wall of the second guide hole 230 is provided with a completely closed internal side wall 230a that defines the fully closed state of the armrest or the upper bracket 100 when the spring 400 hits it, A full opening defining inner wall 230b, an outer inner wall 230c, and an inner inner wall 230d that define the fully open state of the armrest or upper bracket 100 when the spring 400 hits it.

At this time, both ends of the inner wall of the second guide hole 230 preferably meet the spring 400 to define the fully opened state of the armrest and the fully closed state of the armrest. That is, as described above, when the spring 400 collides with the inner wall 230a of the fully closed specified state in which the spring 400 hits the armrest or the fully closed state of the upper bracket 100, the armrest or the upper bracket 100 100 defined in the fully opened state of the inner wall 230b determines the rotation limit of the armrest.

In this case, when the spring 400 is positioned at both ends of the inner wall of the second guide hole 230, the cross-sectional centers c3 and c4 of the spring 400 are inclined at 90 degrees with respect to the axis of the hinge shaft 10 It is preferable to form the central angle [theta] 2.

In other words, since it is general that the armrest is opened in a parallel state and in a vertical state, the center of the cross section c3 when the spring 400 hits the inner wall 230a of the complete closure specification, 2 of 90 degrees with the center of the central axis of the hinge shaft 10 or the lower hinge hole 210 when the center hinge hole 230b is hit.

The spring 400 applies an opening torque to the primary position as shown in FIG. 6 (b) rather than applying an opening torque to the upper bracket 100 until the armrest is fully opened, It has been experimentally confirmed that it is more suitable for the user's convenience to be provided by the rotational force of the armrest, but rather to provide the closing rotational force to the primary position when the armrest is closed.

The spring 400 may be rotatably provided together with the rotational motion of the upper bracket 100. In other words, the spring 400 is fixed to both ends of the spring fixing hole 130 provided on both side surfaces of the upper bracket 100, and when the upper bracket 100 is rotated, And can be rotatably provided together with the upper bracket 100 while being guided by the hole 230.

The hinge unit of the armrest of the vehicle according to the embodiment of the present invention is constructed such that the auxiliary bracket 300 moves along the first guide hole 120 of the upper bracket 100, The guide structure of the spring 400 forming the upper bracket 100 is further applied to more effectively achieve stable rotation of the upper bracket 100.

At this time, as described above, it is preferable that both ends of the inner wall of the second guide hole 230 are defined by the spring 400 to collide with the fully closed state of the armrest and the fully closed state of the armrest.

In addition, as described above, when the spring 400 is positioned at both ends of the inner wall of the second guide hole 230, the sectional centers c3 and c4 of the spring 230 are positioned at the center of the hinge shaft 10 It is preferable to form the second central angle [theta] 2 of 90 degrees.
