The invention relates to the technical field of vehicle resistance reduction, in particular to a vehicle surface resistance reduction device and a vehicle. Comprising a body; the first grooves extend in the first direction, the number of the first grooves is multiple, and the multiple first grooves are arranged in the second direction at intervals; an included angle is formed between the first direction and the second direction; the second grooves are formed between the adjacent first grooves, the two ends of each second groove communicate with the corresponding first groove, and the multiple second grooves are formed in the first direction at intervals; the third grooves are formed between the adjacent first grooves, the two ends of each third groove communicate with the corresponding first groove, and the multiple third grooves are formed in the first direction at intervals; the second grooves and the third grooves are arranged in a staggered mode in the second direction. The first groove, the second groove and the third groove jointly change the flow field structure of the surface of the vehicle, the friction resistance between the vehicle and air in the running process is reduced, and resistance reduction of the commercial vehicle in the running process is achieved.
本申请涉及一种车辆减阻技术领域,特别是涉及车辆表面减阻装置和车辆。包括:本体;第一沟槽,第一沟槽在第一方向上延伸设置,第一沟槽设有多个,多个第一沟槽在第二方向上间隔设置;其中,第一方向和第二方向呈夹角设置;第二沟槽,第二沟槽设置在相邻的第一沟槽之间,第二沟槽的两端分别与第一沟槽连通,多个第二沟槽在第一方向上间隔设置;第三沟槽,第三沟槽设置在相邻的第一沟槽之间,并且第三沟槽的两端分别与第一沟槽连通,多个第三沟槽在第一方向上间隔设置;第二沟槽和第三沟槽在第二方向上交错设置。第一沟槽、第二沟槽和第三沟槽共同改变车辆表面的流场结构,降低车辆行驶过程中与空气的摩擦阻力,实现商用车在行驶过程中的减阻。
