Abstract
A personal travel tool comprises a cart with a seat and a steering handle, wherein the seat and the cart are connected with each other via a rotating shaft; two side wheels are further fixed on the seat for reaching the ground via the rotation of the seat; and a limit device for limiting turning stroke of the seat is further arranged on the cart. The seat can rotate relative to the cart; and the gravity center of the human body and the seat can be adjusted in the way that a user stoops or lies back and a steering handle is pulled or pushed. When the gravity center shifts forwards, the seat rotates forwards, the two side wheels naturally decrease to form a four-wheel driving state; and when the gravity center shifts backwards, the seat rotates backwards, the two side wheels naturally rise to form a two-wheel driving state. Therefore, the changing-over between the high and low speed driving states can be conveniently and naturally realized, and better stability is realized; in addition, when the human body leans forwards due to an inertial effect under an emergency brake, the travel tool is automatically converted into the four-wheel driving state, so as to play a buffering role and improve safety property without needing the feet to land on the ground in the entire driving process.
Description
Technical field
The present invention relates to field of vehicles, particularly a kind of individual walking-replacing tool.
Background technology
Individual's walking-replacing tool be solve that urban highway is crowded, the ideal scheme of energy dissipation and environmental pollution.Bicycle, Electrical Bicycle, battery-operated motor cycle are the individual walking-replacing tools of main flow at present.They are two wheel constructions, maneuverability, easy to operate.Bicycle, Electrical Bicycle, battery-operated motor cycle are compared bubble car, miniature four-wheel car, at higher moving velocity and turn to and have better stability under the situation.Because bubble car and four-wheeled are because wheelspan and wheelbase are less, comparing conventional truck stability reduces greatly, can improve its stability by lowering the center of gravity, but center of gravity cross the low limited and vehicle driving posture in the visual field that can make and become lying posture more, and be not suitable for driving in the city.
Yet under lower-speed state, cart need be used the pin auxiliary balance, and this gives to ride and makes troubles, and also makes cart be difficult to accomplish closure designs, drives for inclement weathers such as rainy day and cold wind down and makes troubles.In addition, the flexible motion of both legs during for the ease of usefulness pin auxiliary balance, the seat of cart one all design narrowlyer, and this feasible traveling comfort of riding reduces greatly.
The cart that the fixed type auxiliary wheel is housed is when low speed driving, because auxiliary wheel is higher than driving wheel, so can not keep car body upright; When turning to, higher speed, also has the rollover risk because in fact tilting of car body is equivalent to three-wheel vehicle.
And one mechanism's complexity of lifting mode auxiliary wheel, operation inconvenience, design concept is subject to the viewpoint of " auxiliary balance ", only with pin or hand shift lifting, thereby auxiliary wheel gives ground-surface maximum support power less, have at car body under the situation of certain lateral deviation, this bearing force deficiency is so that car body restores balance, and the rotating shaft of auxiliary wheel is parallel with driving wheel in addition, can not roll on the direction perpendicular to driving wheel, this has hindered the recovery of car body balance greatly.In addition, because the auxiliary wheel design is too small, travels to exist under secondary status and jolt, it is also uncomfortable to ride.Also have other drawback, do not list one by one at this.In a word, the lifting mode auxiliary wheel mechanism is difficult to promote and comes owing to variety of problems.
Summary of the invention
The purpose of this utility model is to provide a kind of can realize convenient, the switching naturally of high, low speed motoring condition, has better stability, and under the situation of emergency brake, can be automatically converted to the four-wheel motoring condition, play buffer action, increased safety performance, in whole driving procedure, pin need not land, thereby can accomplish fully closed individual walking-replacing tool.
For achieving the above object, the technical solution adopted in the utility model is: comprise the cart that has seat and steering handle, said seat links to each other by rotating shaft with cart, also be fixed with two side wheels on the seat, rotation by seat makes side wheel contact with ground, and also is provided with the inhibiting device that is used to limit the seat rotational travel on cart.
The lock that is used for locking or unclamps seat also is installed on the utility model cart; Side wheel is cardan wheel or castor; Side wheel is positioned at the car body stage casing, and four wheel diamondwises are arranged; Side wheel also can be positioned at the place ahead of cart front-wheel both sides or front-wheel; Side wheel is positioned at under-seat or both sides.
Seat of the present utility model cart relatively rotates, and the driver relies on and bends or lie on the back to move to be aided with the center of gravity that spurs or promote to turn to handgrip adjusting self and seat.During the center of gravity reach, seat forwards rotates, and two side wheels descend naturally, becomes the four-wheel motoring condition; Seat rearward rotates when moving after the center of gravity, and two side wheels rise naturally, becomes two to take turns motoring condition.Thereby realized that the high, low speed motoring condition is convenient, switched naturally, has better stability, and under the situation of emergency brake, because the effect of inertia forward lean can be automatically converted to the four-wheel motoring condition, play buffer action, increased safety performance, pin need not land in whole driving procedure.
Description of drawings
Fig. 1 is the utility model four-wheel motoring condition lateral plan; Fig. 2 is that the utility model two is taken turns the motoring condition lateral plan.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in further detail.
Referring to Fig. 1,2, the utility model comprises the cart 3 that has seat 1 and steering handle 5, seat 1 links to each other by rotating shaft 4 with cart 3, on seat 1, also be fixed with two side wheels 2, rotation by seat makes side wheel contact with ground, and also is provided with the inhibiting device that is used to limit seat 1 rotational travel on cart 3.Seat cart relatively rotates, and the driver relies on and bends or lie on the back to move to be aided with the center of gravity that spurs or promote steering handle 5 adjustings self and seat.During the center of gravity reach, seat 1 forwards rotates, and two side wheels 2 descend naturally, becomes the four-wheel motoring condition; Seat 1 rearward rotates when moving after the center of gravity, and two side wheels 2 rise naturally, becomes two to take turns motoring condition.And on cart 3 lock that is used for locking or unclamps seat can also be installed, make that seat 1 can be movable when need switching motoring condition, seat 1 maintains static at ordinary times, further increases stability.
Two side wheels 2 are designed to cardan wheel.Take turns when travelling two, in case unbalanced situation occurs, the driver relies on self gravitation to add both hands to turning to the pulling force of handgrip 5 as long as pulling turns to handgrip 5 and bends to regulate center of gravity immediately, just can to side wheel 2 provide enough to ground-surface bearing force to restore balance.The rotating direction of side wheel 2 has the component perpendicular to vehicle heading at this moment, the resistance that the obstruction vehicle body that can not exist above-mentioned auxiliary wheel to exist recovers.In addition, also can utilize the rotation of the inertia spare seat of human body when brake and acceleration, further facilitate the conversion freely of two states.
