Description
Technical field
The present invention relates to a kind of small-sized electric vehicles, and in particular to a kind of three-wheel or four-wheel electric motor car, more particularly to it is a kind of
Steering mechanism for electric vehicle.
Background technique
With the development of battery, motor and control technology, Segway Human Transporter because its is light and handy, portable, it is mobile flexibly by
The small-sized electric scooter of the welcome of people, especially three-wheel or four-wheel, is relatively easy to manipulate, relatively to user's skill requirement
It is low, therefore can be used as daily walking-replacing tool.
However, center of gravity is higher, in Ackermann steer angle, due to inertia because the use of people when this kind of vehicle being traveling of standing
Effect, if speed is very fast, when steering on the inside of wheel can warp, easily generation overturn accident.
Chinese utility model patent CN205034272U discloses a kind of three-wheel electric scooter, includes vehicle frame, installation
In the headstock of vehicle frame front upper, two front-wheels of vehicle frame front end are mounted on, and are mounted on a rear-wheel of vehicle frame rear end；Institute
Stating vehicle frame includes a support plate, is connected to two support tubes of support plate two sides, is connected to two support tube rear ends
Two rear wheel seats, be connected between two rear wheel seats by more than one connecting plate；One is fixedly connected with below the headstock
A head rod, the support plate top are fixedly connected with a headstock connecting tube, and the head rod and headstock connecting tube are detachable
Connection；Two support tube front ends extend to the front of support plate, there are two the front end of two support tubes is rotatablely connected respectively
Front-wheel seat, and an interlocking bar is connected between two front-wheel seats, interlocking bar both ends are rotated with described two front-wheel seats respectively
Connection, and torsional spring is connected between support plate among interlocking bar；The front-wheel seat and the support tube front end are connected by bolt
It connects, and bolt lower end is towards the vehicle frame back lower place.
In the technical solution, front-wheel is in mating connection in vehicle frame front by front-wheel seat, interlocking bar and torsional spring, passes through center of gravity
Laterally offset control front-wheel steer, and headstock relative frame is fixed, to improve stability of the vehicle when turning to.However,
Using this structure, for vehicle when not turning to, there is also the trends of lateral rotation between vehicle frame and front-wheel, influence vehicle in linear rows
Stability when sailing, the torsional spring stress between interlocking bar and support plate is big and frequently changes, and is easily worn part, influences the whole of vehicle
Body service life.
Therefore, it is necessary to the steering mechanism to this kind of electric vehicle to improve.
Summary of the invention
