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： 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： A vehicle rear structure is provided, including a spoiler device disposed at a rear bumper of a vehicle. The spoiler device includes a movable portion and at least one fixed portion. The movable portion is disposed 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. The at least one fixed portion includes a driving component for driving the movable portion to move in a front-rear direction of the vehicle. A gap exists between the movable portion and the rear bumper. An upper surface of a rear side portion of the movable portion has a protrusive portion formed into a protrusive shape protruding toward an upper side of the vehicle, such that the movable portion shields the gap at the storage position.

摘要： The disclosure provides a vehicle body lower structure, which can improve aerodynamic performance and improve driving stability. 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. The airflow guiding plate includes a first airflow guiding plate and a second airflow guiding plate. The first airflow guiding plate is arranged in front of the left and right front wheels of the vehicle, and the second airflow guiding plate is arranged under the center of the vehicle body. Moreover, the protruding amount of the first airflow guiding plate is different from the protruding amount of the second airflow guiding plate in the deploying position.

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. The vehicle body lower structure further includes: a shaft member, which extends in the left-right direction of the vehicle, thereby rotatably connecting the front end of the airflow guiding plate to the vehicle body; a belt member, one end of which is connected to the airflow guiding plate and the other end thereof is connected the vehicle body; and an actuator, which is used to wind the belt member. In addition, the belt member is bent when the airflow guiding plate moves from the deploying position to the receiving position.

摘要： The disclosure provides a vehicle body lower structure, which may improve aerodynamic performance and inhibit the airflow guiding plate from being over-expanded or detached. 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. The vehicle body lower structure further includes: a hook member, which is provided on the upper surface of the airflow guiding plate. When the airflow guiding plate is in the deploying position, the hook member is locked onto the buckle part of the vehicle body. When the airflow guiding plate is located at the receiving position, the hook member is separated from the buckle part of the vehicle body.
