The invention relates to the technical field of flow guide covers, and discloses an air flow guide device for reducing truck wind resistance, the air flow guide device comprises a bottom plate and a flow guide plate, the left side of the upper surface of the bottom plate is fixedly connected with a first concave connecting piece, the left side of the lower surface of the flow guide plate is fixedly connected with a connecting block, and the connecting block is located on the inner side of the first concave connecting piece; transverse grooves are symmetrically formed in the front portion and the rear portion of the upper surface of the bottom plate, and fixing blocks are symmetrically and fixedly connected to the positions, located on the right side of the first concave connecting piece, of the upper surface of the bottom plate; according to the invention, the flow guide plate can be changed to be inclined between the bottom plate and the flow guide plate by utilizing the arranged concave connecting piece I and the connecting block, so that air can flow back conveniently, or the flow guide plate can be folded to be horizontal, and thus the folding is convenient when the vehicle runs in a height-limited place, and the problem that the flow guide plate can block the vehicle when the vehicle is inclined is avoided.
本发明涉及导流罩技术领域,且公开了一种降低卡车风阻的空气导流装置,包括底板和导流板,所述底板的上表面左侧固定连接有凹形连接件一,所述导流板的下表面左侧固定连接有连接块,所述连接块位于所述凹形连接件一的内侧,且通过转轴与所述凹形连接件一转动连接,所述底板的上表面前方和上表面后方均对称开设有横槽,所述底板的上表面位于所述凹形连接件一的右侧对称固定连接有固定块;本发明中的底板和导流板之间,利用设置的凹形连接件一和连接块,可以改变导流板呈倾斜状,从而便于对空气倒流,或者折叠成水平状,从而方便在限高的地方行驶时折叠,避免倾斜时的导流板会阻挡的问题。
