摘要： The disclosure provides a vehicle body lower structure. The vehicle body lower structure includes an airflow guiding plate that is arranged on the vehicle body of a vehicle and is movable between a receiving position covering the lower part of the vehicle body and a deploying position protruding downward. Specifically, the airflow guiding plate includes a front airflow guiding plate and a rear airflow guiding plate. The front airflow guiding plate is rotatably arranged on the vehicle body with its front end, and the rear airflow guiding plate is rotatably arranged with its front end on the rear end of the front airflow guiding plate, and its rear end is slidably arranged on the vehicle body in the front-rear direction of the vehicle. Moreover, the orientation of the front airflow guiding plate is different from the orientation of the rear airflow guiding plate in the deploying position.

摘要： A spoiler structure includes a base portion that is attached to a vehicle body and a movable flow adjustment portion that is moved relative to the base portion from a front position on a vehicle front side to a rear position on a vehicle rear side via an intermediate position. A rear end of the movable flow adjustment portion is moved upward with movement of the movable flow adjustment portion from the front position to the intermediate position. The rear end of the movable flow adjustment portion is moved downward with movement of the movable flow adjustment portion from the intermediate position to the rear position. A height position of the rear end of the movable flow adjustment portion at the rear position is lower than a height position of the rear end of the movable flow adjustment portion at the front position.

摘要： In an undercover structure according to the present invention, a first cover part that is a lowermost part of an undercover has a first rear end positioned ahead of a front wheel axle. Further, a curved part with a predetermined curvature is formed at the first rear end of the first cover part in a side view. This generates a strong negative pressure in a region ahead of the front wheel axle 21. Accordingly, the flow rate of air flowing to each wheelhouse 23 decreases (the flow rate of the airflow between a road and a vehicle generated along the bottom surface of the first cover part 15a of the undercover 15 increases). This causes an attraction force that attracts the vehicle to a road surface to act on a vehicle body of the vehicle, thereby making traveling stability more excellent.

摘要： A spoiler device is adapted to be installed on a rear edge of a vehicle body component arranged on a vehicle and includes a spoiler body having an upper surface portion and a bent portion bent downward from a rear end of the upper surface portion and a movable mechanism connected to the spoiler body to drive the spoiler body to move relative to the vehicle body component. The spoiler body is movable between a storing position where a front end of the upper surface portion is close to an upper surface of the vehicle body component and an extending position where the upper surface portion extends rearward relative to the vehicle body component via the movable mechanism. Taking an imaginary line extending along the upper surface as a reference, the front end in the extending position is located on or further downward than the imaginary line.

摘要： A vehicle rear structure includes a spoiler device at a rear bumper of a vehicle; a floor panel; left and right side frames at two sides of the floor panel and extending along a front-rear direction of the vehicle; and an impact beam extending along a left-right direction of the vehicle and connected to rear ends of the left and right side frames through a connecting portion. The spoiler device includes a movable portion movable between a storage position connected to the rear bumper and an expansion position protruding from the rear bumper toward a rear side of the vehicle; and at least one fixed portion including a driving component for driving the movable portion to move in the front-rear direction of the vehicle, at a further rear side of the floor panel, and at the connecting portion connected between the left and right side frames and the impact beam.

摘要： A vehicle lower structure includes a deflector panel provided on a vehicle body of a vehicle and movable between a stored position covering a lower portion of the vehicle body and an unfolded position protruding downwards. The deflector panel includes a front deflector panel and a rear deflector panel. The front deflector panel is rotatably arranged on the vehicle body along a first rotation axis with a front end thereof. The rear deflector panel is rotatably arranged on a rear end of the front deflector panel along a second rotation axis with a front end thereof and is rotatably and slidably arranged on the vehicle body along a third rotation axis in a vehicle front-rear direction with a rear end thereof. The rear deflector panel is provided with a guide member protruding upwards. The guide member is covered from above by a covering portion formed on the vehicle body.

摘要： The disclosure provides a vehicle body lower structure. The vehicle body lower structure includes: a deflector, disposed on a vehicle body and movable between a stowed position covering a lower part of the vehicle body and a deployed position protruding downward; and a shaft member, extending in a vehicle left-right direction and rotatably connecting a front end of the deflector to the vehicle body. The deflector is maintained in the deployed position protruding downward by its own weight, and receiving an impact load from below, the deflector moves from the deployed position to the stowed position.

摘要： A bumper spoiler structure includes: a bumper panel provided in a bumper of a vehicle; a bumper spoiler capable of advancing and retreating relative to the bumper panel by being moved in an inside-outside direction of the vehicle; a first actuator movable in the inside-outside direction and configured to move the bumper spoiler in the inside-outside direction; a first controller configured to control the first actuator; a second actuator configured to move the bumper spoiler and the first actuator in the inside-outside direction; and a second controller configured to control the second actuator. When at least one of the first actuator and the first controller is lost in a deployed state in which the bumper spoiler protrudes with respect to the bumper panel, the second controller moves the bumper spoiler and the first actuator toward an inner side of the vehicle by using the second actuator.
