[0033] During the driving of the vehicle, when air blows against the vehicle head 100, the flow guide groove 200 will play a drainage role to guide the air along the flow guide groove 200 to both sides of the vehicle head 100, and at the same time, the air flowing in the flow guide groove 200 will form a laminar flow in the flow guide groove 200, so that the flow speed of the air in the flow guide groove 200 is accelerated, the turbulent air in the high-pressure area directly in front of the vehicle head 100 is sucked into the flow guide groove 200 and forms an orderly air flow, and the air resistance caused by the air pressure in the front of the vehicle head 100 is reduced; the arrangement of the flow guide plate assembly 300 can divide the air flowing along the flow guide groove 200 and divide the flow on both sides of the flow guide plate assembly 300, further accelerate the flow speed of the air near the flow guide plate 310, and then form a beneficial negative pressure area near the flow guide plate assembly 300, accelerate the air in front of the vehicle head 100 to flow to both sides, and further reduce the air resistance in front of the vehicle head 100.

[0034] Refer to Figure 2, the guide groove 200 includes a front part 210, two guide parts 230 and two side parts 220, wherein the front part 210 is arranged in front of the vehicle forehead 100 and extends to both sides of the vehicle forehead 100, the two side parts 220 are arranged on both sides of the vehicle forehead 100 respectively, and the two guide parts 230 are arranged at the corners on both sides of the vehicle forehead 100 respectively, the front part 210 and the two side parts 220 are connected through the two guide parts 230 respectively, wherein the guide part 230 is recessed towards the inner side close to the vehicle forehead 100, and the guide part 230 is connected with the front part 210 and the side part 220 through a smooth curved surface respectively, the side part 220 is arranged in an inclined manner with the side surface of the vehicle forehead 100, so that the side part 220 is connected with the side surface of the vehicle forehead 100 in a smooth transition manner, so as to reduce the influence of the connection between the side part 220 and the side surface of the vehicle forehead 100 on the smooth flow of the air flow when guiding the air flow to the side surface of the vehicle forehead 100.

[0035] With reference to Figure 3 And Figure 4 , the guide plate assembly 300 includes a guide plate 310 and a connecting plate 320, and the guide plate 310 and the connecting plate 320 are arranged in an integrated manner, wherein the guide plate 310 is arranged in an arc shape, and the curvature of the guide plate 310 is the same as the curvature of the corners on both sides of the vehicle forehead 100, the connecting plate 320 is provided with two, and the two connecting plates 320 are arranged above the guide plate 310 and below the guide plate 310 respectively, and the two connecting plates 320 are fixedly installed on the top end surface and the bottom end surface of the corners of the guide groove 200 respectively, so as to fixedly arrange the guide plate 310 at the corners of the guide groove 200.
