Description
Technical field
The utility model belongs to electric automobiles, particularly relates to a kind of battery-driven car of four-wheel.
Background technology
Advantages such as battery-driven car is convenient because of it, environmental protection, and become very popular walking-replacing tool, especially be fit to do old man, disabled person's walking-replacing tool.It generally includes vehicle frame, handlebar, seat, chargeable battery and wheel, and handlebar, seat and wheel are installed on the vehicle frame, and battery provides power to car load, the direction of handlebar control front-wheel and and then the control car load turn to.Because the output torque of chargeable battery is less, connects with wheel shaft as two front-wheels, will feel under power when turning to, therefore existing battery-driven car in the majority with three-wheel only has a front-wheel, and its balance of such three-wheeled electric vehicle is good inadequately again.
Summary of the invention
To be solved in the utility model is the big technical matters of four-wheel electric motor car steering torque, provide a kind of steering torque little, control four-wheel electric motor car flexibly.
It is rotatable that another purpose of the present utility model provides a kind of seat, the four-wheel electric motor car that makes things convenient for the driver to get on or off the bus.
For this reason, the technical solution adopted in the utility model is as follows: four-wheel electric motor car, comprise vehicle frame, handlebar, seat, chargeable battery, two front-wheels and two trailing wheels, handlebar, seat and wheel are installed on the vehicle frame, battery provides power to car load, the direction of handlebar control front-wheel and and then the control car load turn to, two front-wheel inboards are fixed with directed piece respectively; Manage before having vehicle frame under the handlebar, handlebar by vehicle frame before pipe be installed on the vehicle frame, pipe is provided with boss before the vehicle frame, two pilot bars are installed on the boss, pilot bar one end links to each other with boss with universal-joint, the other end links to each other with the directed piece of front-wheel inboard with universal-joint, and when rotating handlebar, pipe orders about the front-wheel rotation by pilot bar before the vehicle frame.
The utility model also can adopt following further technical scheme: connection pipe is arranged on the seat plate, and connection pipe is being connected of rotating in a circumferential direction with vehicle frame, is respectively equipped with seat locating plate and radius stay on the vehicle frame and under the seat plate; Described seat locating plate has the circular arc outer rim, has some breach on its outer rim; Described radius stay comprises limiting stopper, pull bar and locking torsion spring, on the width of limiting stopper and the seat locating plate between two adjacent breach the width of outshot be complementary, pull bar and locking torsion spring match, the control limiting stopper rotates and resets.
The mounting means of seat locating plate and radius stay can have two kinds, and a kind of is that the seat locating plate is set on vehicle frame, divides into radius stay at seat plate; Another kind is that radius stay is set on vehicle frame, divides into the seat locating plate at seat plate, and dual mode can obtain same technique effect.
For improving the traveling comfort of driving, can have handrail on the seat of battery-driven car usually, convenient for getting on or off the bus, the utility model also can adopt following further technical scheme: the chair back both sides of described seat have handrail, and handrail is rotating the connection with the chair back.
For improving the vehicle firmness and controlling safety, also have a pallet on the pipe before the vehicle frame of electric four-wheel vehicle, pipe before handlebar and the vehicle frame is fixed together, control panel is arranged on the pallet; Handlebar is to adopt enclosed being advisable.
The utility model is controlled two front-wheels respectively with two pilot bars, turning to of front-wheel utilizes lever principle to finish, simultaneously with having the universal-joint of adaptivity as Transmission, two front-wheels can distribute required moment as required, can not cancel out each other, therefore whole steering torque is less, controls flexibly; The connection pipe of seat plate is being connected of rotating in a circumferential direction with vehicle frame, make seat can be on vehicle frame rotation relatively, the seat locating plate matches with radius stay, but fixed seat again, seat turns like this, and chaufeur is got on or off the bus easily; Pallet is set on the pipe before vehicle frame, control panel is arranged on the pallet, not only elegant in appearance, also be beneficial to driver's operation, also improved the stability of vehicle structure simultaneously; Enclosed handlebar can not deviate from from driver's hand, helps safety.
