An air mobility device improves propulsion due to the Coandă effect when flying so as to increase a flying range and reduces noise when flying.

Air mobility device using compressed air

A propeller safety device is provided. The propeller safety device is configured to insert a moving part of a propeller into a fixed part during a crash of an air mobility to allow a reduction in the total length of the propeller, thereby preventing the propeller from hitting the ground. Accordingly, a secondary accident due to fragments formed when the rotating propeller hits the ground is prevented.

Propeller safety device

A propeller control system of an air mobility is configured to insert a movable part forming a propeller into a fixed part in a situation where the air mobility is stored and crashes, thereby reducing an entire length of the propeller. As a result, an entire size of the air mobility is reduced when the air mobility is stored, which may prevent secondary accidents caused by fragments generated by contact of the rotated propeller with the ground in the situation where the air mobility crashes.

Propeller control system of air mobility

A propeller apparatus of an air mobility includes a housing having an inner space, where multiple slits are formed along a circumferential surface of the housing to extend in a vertical direction; a driving unit having connection portions formed to match respective ones of the slits in the housing; multiple link units configured to match the respective ones of the slits in the housing, where the link units are rotatably connected to the connection portions, respectively, of the driving unit; and multiple wing units configured to be rotated in a manner of being linked with the link units, which rotate when the driving unit moves up and down, thereby being folded to or deployed from the housing. The propeller apparatus is configured to prevent an accident due to scattering of a propeller when the air mobility falls, and to improve space utilization during storage of the air mobility.

Propeller apparatus of air mobility

A propeller apparatus of an air mobility is arranged such that a propeller is configured to fold when the air mobility crashes, thereby preventing additional accidents caused by fragments generated by the propeller hitting the ground, and enabling the propeller to be reused by unfolding the folded propeller after the air mobility lands.

A vehicle front structure includes: a front side member disposed on a front of a vehicle; a bumper beam mounting bracket joined to a front end surface of the front side member; a subframe mounting bracket joined to a rear surface of the bumper beam mounting bracket, and having a seating surface to which a front end of a front subframe is joined; a heat exchanger support joined to the bumper beam mounting bracket; and a first reinforcing member joining the bumper beam mounting bracket and the heat exchanger support.

Vehicle front structure

A front body structure of a vehicle may be configured such that a cowl cross member connecting shock absorber mounting portions to each other includes a cowl cross member lower portion, a cowl cross member upper extension portion, and a cowl cross member upper portion, wherein the cowl cross member is provided with two first closed space and second closed space that are defined by the cowl cross member upper extension portion to be isolated from each other, and the cowl cross member is connected to a fender apron upper member and a cowl panel through a hood hinge mounting bracket.
