[0037] When a vehicle is running, noise will inevitably be generated after the external airflow collides with the vehicle body, and the noise will be greater when the vehicle is running faster. The noise will affect the riding experience of the driver and passengers, and the traditional flow guide device on the vehicle can only reduce the resistance caused by the external airflow to the vehicle body, and cannot weaken the noise generated after the external airflow collides with the vehicle body.

[0038] In view of this, the present application provides a vehicle, which includes a flow guide device. As long as the vehicle includes the flow guide device, it belongs to the vehicle of the present application. The flow guide device aims to solve the problem that the traditional flow guide device on the vehicle can only reduce the resistance caused by the external airflow to the vehicle body, and cannot weaken the noise generated after the external airflow collides with the vehicle body. Figures 1 to 3 The structural schematic diagram of an embodiment of the flow guide device provided in the present application.

[0039] Please refer to Figures 1 to 3 The flow guide device 100 provided in the present application is installed on a vehicle 200, and the vehicle 200 includes a top shell 210. The flow guide device 100 includes a first flow guide plate 1 arranged on the top shell 210. The first flow guide plate 1 and the top shell 210 define a first air duct 11 therebetween. The first flow guide plate 1 has a first windward side 1a and a first leeward side 1b oppositely arranged along the extension direction of the first air duct 11. The first flow guide plate 1 further has a first air inlet 111 arranged on the first windward side 1a and in communication with one end of the first air duct 11.

[0040] The first leeward side 1b of the first flow guide plate 1 is provided with a first noise reduction part. The first noise reduction part includes a first air outlet 112 in communication with the other end of the first air duct 11 away from the first air inlet 111. The side wall of the first air outlet 112 is configured to reduce the noise generated by the airflow flowing through the first air outlet 112.

[0041] In the technical solution of the present application, the flow guide device 100 is installed on the top shell 210 of the vehicle 200, thereby weakening the noise generated after the external airflow collides with the vehicle body. Specifically, the flow guide device 100 includes a first flow guide plate 1 installed on the top shell 210, and the first flow guide plate 1 can define a first air duct 11 with the top shell 210. When the vehicle 200 is running, part of the airflow in contact with the vehicle 200 will pass through the first air duct 11. The first air duct 11 is provided with a first noise reduction part at a first air outlet 112 thereof, and when the airflow rushes out of the first air outlet 112 of the first air duct 11, the side wall of the first air outlet 112 can reduce the noise generated by the airflow flowing through the first air outlet 112, thereby weakening the noise generated after the external airflow collides with the vehicle body, and improving the riding experience of the passengers and the driver.

[0042] In some embodiments, the side wall of the first air outlet 112 includes a plurality of first sound absorbing parts arranged at intervals along the circumference of the first air outlet 112, and each first sound absorbing part is recessed outward along the axial direction of the first air duct 11, so that each first sound absorbing part forms a first sound absorbing groove in communication with the first air duct 11.

[0043] The first noise reduction part includes a plurality of first sound absorbing parts, and each first sound absorbing part can form a first sound absorbing groove in communication with the first air duct 11 at the first air outlet 112. When the airflow passes through the first air duct 11 and passes out of the first air outlet 112, it will enter the plurality of first sound absorbing grooves, and the noise generated by the airflow will repeatedly reflect in the corresponding first sound absorbing groove, thereby weakening the noise generated by the airflow.

[0044] When the conventional vehicle 200 is running, the airflow will hit the front end of the vehicle 200, so the front end of the conventional vehicle 200 is generally provided with a slope to guide the airflow to the top of the vehicle 200, thereby reducing the resistance of the airflow to the vehicle 200. At this time, part of the airflow may be difficult to enter the first air duct 11 from the first air inlet 111 due to the flow angle, resulting in that the noise reduction effect of the first flow guide plate 1 is not ideal. Therefore, in some embodiments of the present application, the flow guide device 100 further includes a second flow guide plate 2 installed on the top of the first flow guide plate 1, and the second flow guide plate 2 and the top of the first flow guide plate 1 define a second air duct 21 therebetween, and the second flow guide plate 2 has a second windward side and a second leeward side oppositely arranged along the extension direction of the second air duct 21.

[0045] The second flow guide plate 2 further has a second air inlet 211 provided on the second windward side and in communication with one end of the second air duct 21. The second leeward side of the second flow guide plate 2 is provided with a second noise reduction part 22, and the second noise reduction part 22 includes a second air outlet 212 in communication with the end of the second air duct 21 away from the second air inlet 211. The side wall of the second air outlet 212 is configured to reduce the noise generated by the airflow flowing through the second air outlet 212.

[0046] The second flow guide plate 2 and the first flow guide plate 1 define a second air duct 21, and the second flow guide plate 2 is also provided with a second noise reduction part 22. In actual application, the airflow that is difficult to enter the first air duct 11 can enter the second air duct 21 through the second air inlet 211, and the airflow entering the second air duct 21 can flow out from the second air outlet 212. When the airflow flows out from the second air outlet 212, the second noise reduction part 22 at the second air outlet 212 can weaken the noise generated by the airflow, thereby further weakening the noise of the airflow and improving the riding experience of the passengers and the driver.

[0047] In some embodiments, the sidewall of the second air outlet 212 includes a plurality of second sound absorption parts 221 arranged at intervals along the circumference of the second air outlet 212, and each second sound absorption part 221 is recessed outward along the axial direction of the second air duct 21, so that each second sound absorption part 221 forms a second sound absorption groove 221a in communication with the second air duct 21.

[0048] The second noise reduction part 22 includes a plurality of second sound absorption parts 221, and each second sound absorption part 221 can form a second sound absorption groove 221a in communication with the second air duct 21 at the second air outlet 212. When the airflow passes through the second air duct 21 and flows out from the second air outlet 212, it enters the plurality of second sound absorption grooves 221a, and the noise generated by the airflow is repeatedly reflected in the corresponding second sound absorption grooves 221a, thereby weakening the noise generated by the airflow.

[0049] In some embodiments, the second flow guide plate 2 is arranged close to the first leeward side 1b of the first flow guide plate 1. When the conventional vehicle 200 is driving, the airflow will hit the front end of the vehicle 200, so the front end of the conventional vehicle 200 is generally provided with a slope, and the airflow will flow obliquely upward to the upper side of the vehicle 200, thereby reducing the resistance of the airflow to the vehicle 200. At this time, part of the airflow may be difficult to enter the first air duct 11 due to the flow angle, resulting in that the noise reduction effect of the first flow guide plate 1 is not ideal. When the second flow guide plate 2 is arranged close to the first leeward side 1b of the first flow guide plate 1, the airflow flowing obliquely upward can enter the second air duct 21 through the second air inlet 211, so that more airflow enters the second air duct 21, thereby making the noise reduction effect of the second flow guide plate 2 better.

[0050] In the driving process of the vehicle 200, the vehicle 200 often needs to decelerate, and the commercial vehicle is difficult to brake in time in some cases. Therefore, in some embodiments, the first flow guide plate 1 is provided with a rotating opening 12. The flow guide device 100 further includes a deceleration plate 3 rotatably arranged in the rotating opening 12, and the deceleration plate 3 is configured to block the rotating opening 12 or extend out of the rotating opening 12 in the rotating process.

[0051] When the vehicle 200 needs to decelerate, the deceleration plate 3 can extend the rotating opening 12 by rotating, so that the deceleration plate 3 can block part of the airflow, thereby increasing the resistance of the vehicle 200 when driving. When the vehicle 200 is driving normally, the deceleration plate 3 adjusts the position by rotating, so that the deceleration plate 3 can block the rotating opening 12 to avoid affecting the vehicle 200. The deceleration plate 3 can assist the vehicle 200 to brake, thereby increasing the driving safety of the vehicle 200.

[0052] When the vehicle 200 is driving at different speeds, the speed of the airflow around the vehicle 200 will also be different, which makes the flow direction of the airflow different. Therefore, in some embodiments, the first windward side 1a of the first deflector plate 1 is hinged to the top shell 210. The flow guiding device 100 further comprises a driver connected to the first leeward side 1b of the first deflector plate 1, and the driver is configured to drive the first deflector plate 1 to rotate around the first windward side 1a thereof to adjust the orientation of the first deflector plate 1.

[0053] The flow guiding device 100 drives the first deflector plate 1 to rotate by the driver, thereby adjusting the orientation of the first deflector plate 1, so that the orientation of the first deflector plate 1 can correspond to the flow direction of the current airflow, thereby making the noise reduction effect of the first deflector plate 1 better. When noise reduction is not needed, the driver is controlled by the driver to rotate the first deflector plate 1 to be attached to the top shell 210 of the vehicle 200, thereby avoiding interference with the driving of the vehicle 200.

[0054] When the first deflector plate 1 rotates, the first deflector plate 1 can adjust the orientation to correspond to the flow direction of the current airflow, thereby making the noise reduction effect of the first deflector plate 1 better. Specifically, the included angle between the extension direction of the first deflector plate 1 and the length direction of the vehicle 200 is greater than or equal to 0 degrees and less than or equal to 25 degrees. Of course, the adjustment range of the first deflector plate 1 can be larger or smaller, and the specific adjustment range can be adjusted adaptively according to the use requirements.

[0055] In some embodiments, the flow guiding device 100 further comprises a driving parameter sensor and a controller. The driving parameter sensor is used to sense one or more of the height of the cargo box of the vehicle 200, the speed of the vehicle 200, and the outside wind speed. The controller is electrically connected to the driving parameter sensor and the driver, respectively, and the controller is configured to control the output of the driver according to the data sensed by the driving parameter sensor.

[0056] The vehicle 200 senses the driving parameters by the driving parameter sensor, and the controller can determine the current appropriate working angle of the first deflector plate 1 according to the driving parameters. The controller can control the driver to work according to the working angle, so that the first deflector plate 1 can be rotated and adjusted to the corresponding working angle, thereby ensuring the noise reduction effect of the first deflector plate 1.

[0057] Specifically, the driving parameter that the driving parameter sensor can sense can include one or more of the height of the cargo box of the vehicle 200, the speed of the vehicle 200, and the speed of the external wind. Of course, the driving parameter sensor can also determine the corresponding working angle of the first deflector 1 by sensing other parameters, and the specific driving parameter that is sensed can be adjusted according to the actual application scenario.

[0058] In addition, the driving parameter sensor can actually include one or more of a speed sensor, a radar, or a height sensor, and the specific implementation of the driving parameter sensor can be adjusted and selected according to the use demand.

[0059] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure as long as the combination does not exist.

[0060] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
