Detailed Description

In order that the above objects, features and advantages of the present invention may be more clearly understood, a solution of the present invention will be further described below. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those described herein; it is to be understood that the embodiments described in the specification are only a part of the embodiments of the present invention, and not all of them.

As shown in fig. 1 to 3, the air guiding device provided by the embodiment of the utility model includes an air guiding plate 4 and a driving member disposed at the rear of a vehicle body, and specifically, the air guiding plate 4 and the driving member are disposed above the rear of the vehicle body. The length direction of the air deflector 4 is adapted to the width direction of the vehicle body, and the adaptation means that the length direction of the air deflector 4 is the same as or close to the width direction of the vehicle body. Guide plate 4 rotates along its length direction and sets up on the automobile body, and the driving piece is used for driving guide plate 4 and rotates, and when the driving piece drove guide plate 4 and rotates, guide plate 4 can lift up or fall towards one side of the fin 2 of automobile body. Specifically, when the spoiler 4 is raised toward the side of the rear wing 2 of the vehicle body, the air flow can be directed upward of the rear wing 2.

As shown in fig. 4, the vehicle includes a vehicle body, and a roof 1, a back door glass 3 and a tail wing 2 provided on the vehicle body, and the present invention provides a deflector 4 and a driving member on the vehicle body. As shown in fig. 2, the baffle 4 maintains its original shape when the vehicle is stationary or running at a low speed. When the vehicle-mounted computer ECU monitors that the vehicle speed does not reach 100km/h, the vehicle is judged to be in a low-speed state, the driving piece drives the guide plate 4 to be closed or to be kept in an original state, and at the moment, the influence of the wind resistance of the whole vehicle on the oil consumption is small, so that the airflow is allowed to flow through a hollow area between the tail wing 2 and the back door glass. Further optimally, a support piece can be arranged on the vehicle body, and in a normal state (the vehicle is static or runs at a low speed), the support piece is supported at the bottom of the guide plate 4, so that the situation that the guide plate 4 is continuously kept through the driving piece is avoided, and the service life of the driving piece is prolonged. The structure and the arrangement mode of the support member are not limited, and the support member only needs to play a role of supporting the guide plate 4, so that the support member is not illustrated in the figure.

As shown in fig. 3, when the vehicle is in a high-speed driving state, that is, when the vehicle-mounted computer ECU monitors that the vehicle speed reaches 100km/h, the driving member drives the guide plate 4 to rotate, so that the guide plate 4 is lifted towards one side of the tail wing 2 of the vehicle body, wherein the lifting height of the guide plate 4 is designed according to the vehicle type, and the lifted guide plate 4 is positioned above the tail wing 2 towards one side of the tail wing 2, so that the airflow flows through the top of the guide plate 4, the airflow flowing through the cavity area of the tail wing 2 is reduced, and the wind resistance of the whole vehicle is reduced.

According to the utility model, the guide plate 4 is arranged at the tail part of the vehicle body, when the vehicle runs at high speed, the driving part drives the guide plate 4 to rotate, so that the guide plate 4 is lifted towards one side of the tail wing 2, and airflow flows through the top of the guide plate 4, thereby preventing the airflow from flowing to a hollow area between the tail wing 2 and the back door glass 3, reducing the rear vortex and the wind noise level of the vehicle, reducing the wind resistance of the whole vehicle, reducing the oil consumption and improving the aerodynamic performance.

In some embodiments, the deflector 4 is provided with a rotating shaft 6, the installation direction of the rotating shaft 6 is adapted to the width direction of the vehicle body, where the adaptation means that the installation direction of the rotating shaft 6 is the same as or close to the width direction of the vehicle body, and the driving member is used for driving the rotating shaft 6 to rotate, so as to drive the deflector 4 to rotate through the rotation of the rotating shaft 6. Further optimally, the rotating shaft 6 is arranged on one side, far away from the tail wing 2, of the guide plate 4, so that when the side, far away from the tail wing 2, of the guide plate 4 rotates to a set height, the rotating stroke of the rotating shaft 6 is minimum, and the opening efficiency of the guide plate 4 is increased. Preferably, the driving member includes a driving motor 5, an output shaft of the driving motor 5 is connected to the rotating shaft 6, and in order to reduce the rotating speed of the rotating shaft 6, a speed reducer may be connected to the output shaft of the driving motor 5, and the rotating shaft 6 is connected to the output shaft of the speed reducer. The position of the driving motor 5 is not limited, as long as the driving motor can drive the rotating shaft 6 to rotate and can be hidden in the vehicle body.

Referring to fig. 1 to 3, in some embodiments, the air deflector 4 is rotatably disposed between the ceiling 1 and the back door glass 3 of the vehicle body, so as to avoid increasing the height of the whole vehicle, and specifically, a groove may be disposed at a position of the ceiling 1 close to the back door glass 3, and the air deflector 4 is installed in the groove. And when the guide plate 4 is lifted up, a gap exists between the guide plate 4 and the tail wing 2, so that in order to prevent rainwater from flowing to the groove through the gap, a rubber shielding plate can be arranged on one side of the tail wing 2 facing the guide plate 4, and the rubber shielding plate covers one end of the guide plate 4 facing the tail wing 2. When the guide plate 4 is lifted, the end part of the guide plate 4 is gradually separated from the rubber shielding plate until the guide plate 4 is completely lifted, and the rubber shielding plate is separated from the guide plate 4 and restores to the original position, so that the end part of the rubber shielding plate is supported on the inner side of the guide plate 4. On the contrary, when the guide plate 4 falls down, the guide plate 4 drives the rubber shielding plate to move downwards, and the rubber shielding plate bounces and covers the end part of the guide plate 4 after the guide plate 4 falls back to the proper position. Make the sealed guide plate 4 of rubber sunshade through this kind of design, avoid the rainwater to pass through clearance infiltration. In addition, even the rainwater passes through the clearance infiltration, also can enter into the recess, can set up water drainage tank in one side of recess, avoids the rainwater in the recess to pile up.

As shown in fig. 1 and 2, one side of the guide plate 4 facing the back door glass 3 is a slope, and when the guide plate 4 is lifted to a set height, the slope abuts against the end of the back door glass 3, so that the phenomenon that the lifting height of the guide plate 4 is too large and the wind resistance is increased is avoided. Specifically, the guide plate 4 is triangular prism-shaped, and has a stable structure, and a slope surface is formed on one side of the guide plate 4 facing the back door glass. Further optimally, the guide plate 4 is provided with the rotating shaft 6, the driving piece is used for driving the rotating shaft 6 to rotate, and the rotating shaft 6 is arranged on the edge of the guide plate 4 opposite to the slope surface, so that the structure is minimized, and the occupied space is reduced.
