Title:
POWER VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/076225
Kind Code:
A1
Abstract:
Provided is a power vehicle, comprising: a body (110), a head part (111), a cabin part (112) and a rear part (113); a front wing element (120) longitudinally arranged at the head part (111), wherein the front wing element (120) has an upper curved face (120a) bent upwards and a lower curved face (120b) bent upwards; and an aerodynamic device (130) longitudinally arranged at a bottom part of the vehicle, and constructed to make air flowing through same expand and generate a negative pressure, wherein when the power vehicle moves, the pressure of a vehicle bottom fluid flowing through the vehicle body bottom via the aerodynamic device (130) from the lower curved face (120b) of the front wing element (120) is lower than the pressure of a vehicle top fluid flowing through the vehicle body top via the upper curved face (120a) of the front wing element (120). According to the vehicle, by means of the combination of the front wing element and the aerodynamic device, a negative pressure is generated at the vehicle body bottom and downward pressures are thus generated, and the pressure centres of these downward pressures all maintain a stable front-back distribution proportion within a certain trim angle range, so that convection air can push the power vehicle to maintain contact with the ground, thereby effectively preventing the vehicle head from being lifted off the ground and even somersaulting backwards within a large trim angle range.
