Embodiment Construction
[0024] The present invention will be further described below in conjunction with specific embodiments. It should be understood that the following examples are only used to illustrate the present invention but not to limit the scope of the present invention.
[0025] combine figure 1 , figure 2 As shown, according to a preferred embodiment of the present invention, a kind of active spoiler structure that can be rotated and opened is provided, and the spoiler 1 in the active spoiler structure is matched with the shape of the tailgate 100 in the closed state. The wind resistance of the whole vehicle has no effect.
[0026] combine image 3 , Figure 4 As shown, the spoiler 1 in the active spoiler structure forms a passage for air flow between the spoiler 1 and the tailgate 100 in the open state, thereby reducing air resistance, realizing energy saving and emission reduction of the vehicle, and improving the service life of the new energy battery , At the same time increase ...

The invention provides an active spoiler structure capable of being rotatably opened, which comprises the following parts: a spoiler mounted at the tail part of an automobile, wherein a first lug anda second lug are arranged on the back surface of the spoiler; a rocker rotating bracket mounted on the back surface of the spoiler through the first lug and the second lug; an auxiliary rocker connected with the rocker rotating bracket through the first lug, and the other end of the auxiliary rocker is fixed on a rack fixed pressing plate; a motor in signal connection with a trip computer; a rotating shaft driven by the motor to rotate; a gear sleeved at the tail end of the rotating shaft and can rotate along with the rotating shaft; a sliding rack with one end meshed with the gear and the other end connected with the rocker rotating bracket. According to a real-time automobile speed, under the control of the trip computer, the spoiler can be rotationally started from a closed position andstays at the optimal angle capable of reducing wind resistance to the maximum extent and improving the pressure under the air. According to the active spoiler structure provided by the invention, high-speed safe driving and green, environment-friendly, energy-saving and emission-reducing effects are realized.
Description
technical field [0001] The invention relates to the field of spoilers, in particular to a rotatable and openable active spoiler structure. Background technique [0002] At present, in order to reduce the wind resistance of the whole vehicle, one of the measures usually adopted is to increase the air downforce of the vehicle at high speed. Specifically, a fixed spoiler or a four-bar linkage structure with relatively poor stability is used to drive the spoiler to open and close. . However, in this assembly form, the accumulative assembly error of the spoiler is large, the processing accuracy of the parts themselves is extremely high, and the parts rely on high-torque motors for high control. Therefore, how to adapt to vehicle speed changes with low cost and high efficiency, and provide an active spoiler that can be opened and closed according to different driving conditions to reduce wind resistance and increase vehicle air downforce is an urgent problem to be solved.
