Description

Steering limiting device of riding electric vehicle and control method thereof

Technical Field

The invention relates to the field of electric bicycles.

Background

Electric bicycle is vehicle commonly used, its nimble convenient characteristic makes it can walk in narrow and small interval, because electric bicycle generally is two-wheeled structure, its front wheel is the directive wheel, if it is lower too big to deflect, if deflect to the front wheel axis and rear wheel axis perpendicular, then probably cause the car turnover, therefore the front wheel of electric motor car all has limit structure, it is lower to restrict its turning to guarantee driving safety, but under the state of not riding (push away), because receive and turn to the restriction, then when operations such as turn round, move, it is comparatively heavy, need many times to adjust just can reach ideal requirement, bring inconvenience for the use.

Disclosure of Invention

The invention aims to solve the technical problem of realizing a steering limiting device of a riding electric vehicle, which can limit the steering range under the riding state without limiting the steering of a front wheel under the non-riding state.

In order to achieve the purpose, the invention adopts the technical scheme that: the electric motor car of riding turns to limiting device, and the electric motor car of riding is equipped with the steering spindle, the steering spindle is fixed on the frame, the lower extreme of steering spindle is fixed with the front wheel, and the upper end is fixed with the handlebar hand, the rigid coupling has c shape limit structure on the steering spindle, be fixed with electronic jar on the frame, electronic jar telescopic link is the gag lever post, and when electronic jar shrink, the open position of c shape limit structure is stretched out to the gag lever post, and when electronic jar extended, the gag lever post stretched into the turned angle of restriction steering spindle in the open position of c shape limit structure.

The device is provided with a controller, the controller is connected with a battery through a key knob, and the controller is connected with an electric cylinder and controls electric work.

And a position sensor is fixed on the steering shaft and outputs a sensing signal to the controller.

The end part of the limiting rod is of an inward-concave arc structure.

The control method based on the riding electric vehicle steering limiting device comprises the following steps:

when the riding electric vehicle is powered on, the controller acquires the position sensor, and when the signal of the position sensor is within a preset limiting range, the electric cylinder is driven to extend out of the limiting rod;

after the electric motor car of riding cuts off the power supply, the electronic jar of controller drive retracts the gag lever post.

The invention has the advantages that the steering of the front wheel can be limited according to the state of the vehicle, the riding safety can be ensured, and the position of the electric vehicle can be conveniently adjusted in the non-riding state.

The following is a brief description of the contents of each figure and the symbols in the figures in the description of the invention:

FIG. 1 is a schematic structural view of a steering limiting device of a riding electric vehicle;

the labels in the above figures are: 1. a steering shaft; 2. a limiting structure; 3. an electric cylinder; 4. a limiting rod.

Detailed Description

The following description of the embodiments with reference to the drawings is provided to describe the embodiments of the present invention, and the embodiments of the present invention, such as the shapes and configurations of the components, the mutual positions and connection relationships of the components, the functions and working principles of the components, the manufacturing processes and the operation and use methods, etc., will be further described in detail to help those skilled in the art to more completely, accurately and deeply understand the inventive concept and technical solutions of the present invention.

The electric bicycle for riding is provided with a steering shaft 1, the steering shaft 1 is fixed on a bicycle frame, a front wheel is fixed at the lower end of the steering shaft 1, a handlebar is fixed at the upper end of the steering shaft 1, a c-shaped limiting structure 2 is fixedly connected onto the steering shaft 1, an opening of the c-shaped limiting structure 2 is used for limiting the rotation angle of the steering shaft 1, and the electric bicycle can be designed according to requirements, wherein if the angle is 60 degrees, the central position of the opening of the c-shaped limiting structure 2 is arranged, and a connecting line from the opening to the center of the c-shaped limiting structure 2 is vertical to the axis.

Be fixed with electronic jar 3 on the frame, 3 telescopic links of electronic jar are gag lever post 4, when 3 contractions of electronic jar, gag lever post 4 stretches out c shape limit structure 2's open position, steering spindle 1 can 360 degrees rotations in theory this moment, when 3 extensions of electronic jar, gag lever post 4 stretches into the turned angle of restriction steering spindle 1 in c shape limit structure 2's the open position, the rotation angle of steering spindle 1 is the opening size this moment, need have a little clearance between the tip of gag lever post 4 and the steering spindle 1, avoid wearing and tearing steering spindle 1, in order to guarantee the spacing reliability of gag lever post 4, the tip of gag lever post 4 is inside sunken arc structure.

The device is provided with a controller, the controller is connected with a battery through a key knob, and the controller is connected with the electric cylinder 3 and controls electric work. A position sensor is fixed on the steering shaft 1 and outputs a sensing signal to a controller, so that the time for limiting the steering angle can be controlled;

the control method based on the steering limiting device of the riding electric vehicle comprises the following steps: when the riding electric vehicle is powered on, the controller acquires the position sensor, and when the signal of the position sensor is within a preset limiting range, the electric cylinder 3 is driven to extend out of the limiting rod 4; after the electric motor car of riding cuts off the power supply, the electronic jar 3 of controller drive retracts gag lever post 4.

The invention has been described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the specific implementation in the above-described manner, and it is within the scope of the invention to apply the inventive concept and solution to other applications without substantial modification.
