Description

Door guard unit {DOOR GUARD UNIT}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door guard unit, and more particularly, to a door guard unit provided on an outer surface of a door for a vehicle and having a turn guard that can prevent damage to the door when the door is opened.

Generally, in a narrow parking lot, disputes arising from contact with a side vehicle, so-called 'mooncock', occur unobtrusively, and if not taken appropriate measures are taken as escapes.

Regarding the contact with these side vehicles, 83% of the respondents in Spain said they had been careful about damaging the side car when they opened the car, and 72% of the respondents in France. In this regard, many drivers are monitoring with a contact-resistant sponge, door guard, alarm, and black box. In fact, in recent years, there has been a case of continuing from "contact → image analysis → loan inquiry → compensation".

On the other hand, there are many applications and disclosures relating to the contact prevention apparatus of vehicles in addition to the Korean Public Utility Model 20-1998-046115 (hereinafter referred to as the "prior art document").

However, in the case of the conventional door guard, separation for replacing the door guard in a manner of directly attaching to the side surface of the vehicle is not easy, and there is a possibility that the painted color of the vehicle may be peeled off.

In order to solve this problem, there is a door guard which is developed in a detachable manner rather than an attachment type. However, the detachable door guard is not easy to use because it is installed every time of parking and disassembled every time it is run.

The matters described in the background section are intended to enhance the understanding of the background of the invention and may include matters not previously known to those skilled in the art.

SUMMARY OF THE INVENTION An object of the present invention is to provide a door guard unit that improves the stability and convenience of a vehicle by preventing damage to a door that may be caused by collision with an external vehicle or an obstacle when the door of the vehicle is opened.

In order to achieve the above object, according to a door guard unit according to an embodiment of the present invention, a through hole is formed at one side of a door outer panel, and a door is provided rotatably inside the door outer panel corresponding to the through hole The turn guard is fixed to the inner side of the door outer panel with the shock absorbing foam of the turn guard protruding through the through hole to be connected to the turning center of the turn guard through a rotation shaft, And an actuator for rotationally driving the actuator.

The turn guard may be formed by attaching an impact absorbing foam and a shell plate to a circular bar material formed by forming a certain section of the outer circumferential surface in a plane.

In the turn guard, the shock absorbing foam may be attached to an outer peripheral surface of the circular bar material other than the plane, and the outer skin plate may be attached to both the plane of the circular bar material and both ends of the impact absorbing foam.

Wherein the door is opened and closed according to a signal sensed by the sensing unit, and when the door is closed, the impact absorbing foam is positioned inside the through hole And control logic for controlling operation of the actuator such that the shock absorbing foam is exposed through the through hole when the door is closed.

The actuator may rotate the turn guard 180 degrees apart.

The shock-absorbing foam may be an EVA sponge or rubber.

The outside sheathing can be painted the same as the exterior sheathing color of the door outer panel.

The circular bar may be made of a reinforced plastic material.

The rotation shaft may be rotatably fixed to a bearing bracket formed at one side of the door outer panel through a bearing at the tip.

According to the present invention for achieving this object, when the door of a vehicle is opened, the impact-absorbing foam is protruded to the outside of the outer panel, so that damage to the door can be prevented in advance.

In addition, when the door is closed, the outer plate having the same shape and color as the outer panel is exposed, and the impact-absorbing foam is protruded only when the door is open, thereby preventing the appearance of the vehicle.
In addition, a flat portion is formed on a circular shaft member, a flat portion is formed of the same material as the outer shape of the door, an impact absorbing foam is formed on the circular outer peripheral surface, By protruding the absorbent foam or exposing the flat surface, the gap between the door surface and the circular bar can be minimized to improve the appearance quality.
