Retractable OUTSIDE DOOR HANDLE ASSEMBLY USING LATERAL TRACTION FOR VEHICLE

The present invention is a side traction method for a vehicle that can move the handle part by moving the handle part forward or backward by inserting a part of the handle part into the guide groove of the rotation part by rotating the rotation part formed by extending the guide groove on the outer circumferential direction. It relates to an outside door handle assembly.

In a vehicle, a door handle is mounted on the outside of the door so that the driver can board the vehicle from the outside. In general, these door handles have a shape in which the exterior protrudes. However, for the sake of the recent appearance, the door handle is normally located inside the door, and for horizontal or diagonal projecting or flat type (hereinafter referred to as "flat type") outside door handle only when necessary for boarding the vehicle. Demand is increasing.

All vehicles are prevented from being separated from the vehicle body through the fastening of the striker and the door latch, so it is necessary to separate the fastening of the two parts before the driver can get on the vehicle. Generally, the cable connected to the door handle or key is required. Striker and door latch were separated by towing. Occasionally, a motor is used to tow a cable without using a handle or key, but it has been difficult to apply to a flat door handle due to excessive price and volume.

In addition, when the flat door handle is mounted on the door, the thickness should be designed to be 65-70 mm or less so as not to interfere with the inner door glass. In order to realize this requirement, the conventional flat door handle is folded and opened when closed. Various links (joints), etc. were used to open the poem.
