An embodiment vehicle body includes a roof side rail, a front pillar connected to a front portion of the roof side rail, and a roof side reinforcement extending along the roof side rail and the front pillar, wherein the roof side reinforcement is fixedly received in a cavity of the roof side rail and a cavity of the front pillar.

Vehicle body structure

An embodiment front pillar reinforcement system of a vehicle includes a front pillar inner having a first plurality of walls defining a first cavity, a front pillar outer facing the front pillar inner and having a second plurality of walls defining a second cavity, and a front pillar inner reinforcement received in the first cavity of the front pillar inner and having a third plurality of walls coupled to the first plurality of walls of the front pillar inner, respectively.

Vehicle front pillar reinforcement system

An embodiment vehicle body side structure includes a front pillar located behind a front wheel, the front pillar comprising a chamfer surface that is diagonally inclined from a lower portion of the front pillar towards an interior of a vehicle, the chamfer surface being aligned with the front wheel in a longitudinal direction of the vehicle, and a side sill connected to the lower portion of the front pillar.

Vehicle body side structure

In accordance with an embodiment, a vehicle body structure includes: a roof side rail; a front pillar connected to the roof side rail; a cowl member connected to the front pillar, and extending in a width direction of a vehicle; a cowl cross bar located below the cowl member, connected to the front pillar, and extending in the width direction of the vehicle; and a connection bracket connecting the front pillar, the cowl member, and the cowl cross bar.

A display device includes a display area and a non-display area disposed around the display area and including a pad area. The display device includes a resistance checker disposed in the non-display area, resistance test pads disposed in the pad area, resistance test lines connecting the resistance checker with the resistance test pad, and crack test lines disposed on the outer side of the resistance checker. The resistance test lines intersect the crack test lines in a plan view.

Display device

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 display device includes a substrate including a first pixel region, a second pixel region having an area smaller than that of the first pixel region, and a peripheral region surrounding the first pixel region and the second pixel region, a second pixel provided in the second pixel region, a second line connected to the second pixel, an extension line extended to the peripheral region, a dummy part located in the peripheral region to overlap with the extension line, a power line connected to the first and second pixel regions, and a connection line located in the peripheral region to be connected to the dummy part, the connection line being electrically connected to a portion of the second pixel region, wherein the second pixel region includes a first sub-pixel region connected to the connection line and a second sub-pixel region except the first sub-pixel region.

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 display device includes a pixel circuit, a first line disposed on the pixel circuit and a second line disposed on a same layer as the first line. A light emitting element is disposed on the first line and the second line. A connection pattern is disposed on a same layer as the first line and the second line and is disposed between the first line and the second line. The connection pattern connects the pixel circuit and the light emitting element. The connection pattern has a polygonal shape including at least six sides. A first vertex of the connection pattern is positioned at a shortest distance from the first line to the connection pattern and portions of the connection pattern between the first vertex and adjacent vertices are positioned farther from the first line than the first vertex.

Display device including a connection pattern

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.
