Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flush door handle assembly for a vehicle including a blocking lever,

The present invention relates to a vehicle flush door handle assembly including a blocking lever, and more particularly, to a vehicle flush door handle assembly including a blocking lever for preventing a handle portion from being pulled out by an inertial force generated by an external force applied to a door panel .

Generally, the door of the vehicle is provided with a handle portion protruding outside the door panel to open and close the door. When the handle portion is provided so as to protrude outwardly, there is a problem that the handle portion is damaged by an external impact, the fuel cost is lowered due to wind resistance when the vehicle is running, wind noise is generated by wind, and driving noise is generated.

In recent years, in order to solve such a problem, a flush door handle has been developed in which a handle portion is embedded in a door panel except when the door is opened. Korean Patent No. 1637820 (hereinafter referred to as Patent Document 1) discloses such a retractable handle device for a vehicle.

Referring to Fig. 1, the retractable handle device for a vehicle 100 disclosed in Patent Document 1 normally keeps the housed state (a) in which the handle 140 is located inside the door panel 1, The handle 140 is pulled out to become the pop-up state (c).

The handle 140 is rotatably coupled to the driving arm 130 and the driving arm 130 is rotated by the electric actuator 110. When the electric actuator 110 is operated, The controller 140 moves from the stored state (a) to the pop-up state (c) while rotating.

That is, the through hole through which the handle 140 is drawn out from the door panel 1 is formed to have a size considering the turning radius of the handle 140, and therefore, as shown in the pop-up state of FIG. 1 (c) A clearance is generated between the through hole 140 and the through hole.

As described above, when a clearance is generated between the handle and the through hole at the time of pulling in or pulling out the handle, the foreign matter may flow into the retractable handle device through such clearance and cause a malfunction and malfunction of the device And there is a problem that the user is deteriorated in aesthetic sense.

When an external force is applied to the door panel 1 due to an accident or the like, an inertial force is generated in the direction in which the handle 140 is pulled out, There is a problem that the handle 140 may be pulled out and the handle 140 may be broken or the door may be opened to cause an additional accident of the occupant.

With this configuration, when the user pulls the handle 300 at the pop-up position where the handle 300 is drawn out, the handle 300 rotates to rotate the open lever 730 together and the open lever 730 The flange portion 712 rotates to rotate the door open power generating portion 720 to pull the cable fastened to the cable fastening member 722 to generate power for opening the door .

FIG. 20 is a perspective view showing a state in which the blocking lever is provided in the vehicle flush door handle assembly, FIG. 21 is a perspective view showing a state in which the blocking lever is operated, FIG. 22 is a state As shown in Fig.

20 to 22, the blocking lever 800 is rotated at a predetermined angle with the rotary part 500 by an inertial force generated by applying an external force F to the door panel 10, (500) to prevent the handle portion (300) from being pulled out.

That is, when an external force such as an external impact is applied to the door panel 10 due to a vehicle accident or the like, the handle portion 300 is operated to be drawn out to the pop-up position by an inertial force to cause breakage of the handle portion 300 .

Further, a larger external force may be applied to the handle portion 300 to be drawn out to the pop-up position, and then the door may be opened. In this case, there is a problem that can cause additional damage to the occupant.

In the present invention, the blocking lever 800 is provided to prevent the rotary part 500 from rotating when an external force F is applied to the door panel 10, so that the handle part 300 is drawn out It is possible to prevent the door from being opened.

More specifically, the blocking lever 800 includes a lever body 810 that is coupled to the housing 200 to be rotatably coupled to the lever body 810, and a weight 820 that protrudes from the lever body 810 toward the handle unit 300 The lever body 810 protrudes from the lever body 810 toward the rotary part 500 and contacts the rotary part 500 when the lever body 810 and the rotary part 500 rotate at a predetermined angle due to an inertial force, A stopper 830 for restricting the rotation of the rotary part 500 and a blocking part 830 which is disposed between the housing 200 and the lever body 810 and which applies an elastic force to return to the original position when the lever body 810 rotates, And a lever elastic member 840.

That is, when an inertial force is generated due to an external force, the rotary part 500 is rotated by the weight of the handle part 300, and the lever body 810 is rotated by the weight 820, In the same direction. At this time, the stopper 830 rotated together with the lever body 810 contacts the rotary part 500, thereby preventing the rotary part 500 from rotating.

When the rotation unit 500 is rotated by the operation of the power generating unit 600, the avoidance groove 550 through which the stopper 830 passes is formed so as not to contact the stopper 830, When the door panel 10 rotates due to an inertial force generated by an external force applied thereto, the supporting surface 560 is formed to be in contact with and supported by the stopper 830.

In this configuration, when the rotary unit 500 is rotated by the power generating unit 600, the lever body 810 does not rotate, which is a general door opening operation, and the stopper 830 is rotated The rotation of the rotary part 500 is prevented by passing through the avoidance groove 550 formed in the rotary part 500.

When the inertial force is generated by the external force, the rotary part 500 and the lever body 810 rotate together in the same direction. At this time, the stopper 830, which rotates together with the lever body 810, (500), and comes into contact with the support surface (560) of the rotary part (500), thereby restricting the rotation of the rotary part (500).

The lever body 810 is returned to its original position by the blocking lever elastic member 840 and the rotary part 500 is also returned to its original position by the rotary part elastic member 540 .
