Description
Technical field
This technology belongs to anti-rollover field, in particular to a kind of anti-rollover electronic system for electric three-wheel car.
Background technology
In recent years, the advantages such as electric three-wheel car is convenient with it, energy consumption is low, strong operability, are constantly subject to broad masses, particularly the liking of the elderly. But, with the raising of electric three-wheel car popularity rate, the traffic accident caused by the rollover of electric three-wheel car rises year by year. According to traffic police department statistics, the traffic accident that only city, Ziyang causes because of electric three-wheel car every year reaches more than 100, and the car rollover event of electric three-wheel together occurred in the recent period causes 14 people's injures and deaths especially.
The major cause of electric three-wheel car rollover is: as shown in Figure 1, and (a) is stressing conditions when electric three-wheel car is in normal operation. Gravity G on the centripetal force F1 that electric three-wheel car weight is subject in horizontal direction in the heart and vertical direction, the support power F that electric tricycle wheel touchdown point is subject to ground props up. Now, the support power in outboard wheels (left wheel), the centripetal force that gravity and car are subject to forms a lever, fulcrum is a point, and equilibrium relationship is, wherein h is the distance of center of gravity to ground, l is the distance between two wheel touchdown points, for center of gravity is to the horizontal throw of inboard wheel touchdown point. When the centripetal force that electric three-wheel car is subject to constantly increases, for making lever balance, the support power suffered by outboard wheels will constantly decline, and the support power of inboard wheel increases. When the support power that outboard wheels is subject to is reduced to 0 (as Suo Shi (b)), being now the stagnation point of electric three-wheel car rollover, the support power of inboard wheel reaches maximum value, reaches maximum value, and equilibrium relationship is. When centripetal force continues to increase, electric three-wheel car is turned on one's side.
There is relevant anti-rollover electric three-wheel car on the market, as: " patent No. 200920298283 anti-rollover front carriage type electric tricycle ", wagon box is arranged on the front device of driver's seat by this innovation and creation ground, when being mainly used in overcoming the turning of conventional electric tricycle, handlebar, by the dragging of rear wagon box, rocks violent. But, once excessive easily the causing of the speed of trailing wheel gets rid of tail, officer is thrown away. Further, the in-built goods of wagon box too much easily disturbs the sight line of officer. At present, market being applied wider is " Octoid gear " electric three-wheel car, and relevant patent has " patent No. 201,120,405,742 1 kinds of lateral turnover resisting rear-mounted electric three-wheel cars " and " a kind of shaftless anti-rollover electric three-wheel car ".Mainly being characterized as of " patent No. 201120405742 " described invention, the lower section of vehicle frame is installed with crossbeam, and the both sides of crossbeam are by anti-rollover trailing wheel support and connection trailing wheel, and two trailing wheels are provided with inclination angle respectively to inner side so that both sides wheel becomes splayed structure. As shown in Fig. 1 (c), the design of " Octoid gear " reduces the distance h of center of gravity to ground, increases l so that F value increase, the value of F1 reduces. And inboard wheel continues to tilt when electric three-wheel car is turned, reducing h further and increase, the stability of electric three-wheel car improves further. " patent No. 201220243076 " is characterized as two wheels and is rotationally connected by rotating shaft and Wheel mounting bracket, and two wheels are all to outer incline, and wheel and horizontal plane angle scope are 80 degree to 85 degree. The electric three-wheel car that this kind " Octoid gear " designs, employing be all front-wheel drive. Electronic employing front-wheel drive has very big shortcoming, its one, front-wheel is as driving wheel, and when electric three-wheel car accelerates, front-wheel easily skids, and is unfavorable for Power output. Its two, front-wheel is as after driving, front-wheel should be responsible for Power output, is responsible for again turning to, and work burden is big, and heavy headstock can reduce into curved quick degree, it is easy to bring out understeer. Therefore the design of front-wheel is not advocated. In sum, existing electric three-wheel car anti-rollover all adopts simple machinery means, and susceptibility is not high; In addition, concerning user, it is necessary to buy novel anti-rollover electric three-wheel car, just have anti-rollover effect, extremely uneconomical. For this reason, it is proposed to the present invention. The present invention is the anti-rollover device of a kind of polarity formula, after user buys this device, it is possible to be directly arranged on existing electric three-wheel car, reduces the financial loss newly purchasing vehicle.
