Description

a self-balancing car

technical field

The utility model relates to the field of Renli electric vehicles in trackless land vehicles, in particular to a self-balancing vehicle.

Background technique

The traditional two-wheeled manned self-balancing vehicle mainly realizes turning through a swing lever that can swing left and right, wherein, there are two operation modes for the swing lever: one is that the length of the swing lever is longer, and the user is riding When riding, the swing lever is operated by both hands, and the steering of the two-wheel balance vehicle is realized; the other is that the length of the swing lever is relatively short, and the user swings left or right by clamping the swing lever with both legs when riding, and Realize the steering to the two-wheel balance car.

In the above two solutions, in the first technical solution, the user needs to hold the swing rod with both hands all the time when riding, and the swing rod mainly plays a supporting role when the user uses it. Needing to wiggle the sway bar to steer requires some adaptability. In the second solution, the swing rod is always clamped by the legs, and the user's hands or legs are always in a tense state, which is prone to fatigue and the user's experience is poor; in addition, the swing rod is easily pulled by other external forces and interferes with the user's riding. Ride the self-balancing car, causing the self-balancing car to malfunction without the intention of the rider.

Chinese Publication No. CN 104386183 A discloses the structure of the left and right pedals disclosed in the two-wheel balance car. Although a technology that solves the existing problems of the swing bar is proposed, the left and right pedals need to be equipped with distance sensors. By comparing the difference between the left and right distance sensors To make a steering change, the control analysis is more complicated. In addition, because the center of gravity of the person on the balance bike is inherently swaying, it is impossible to ensure that the strokes of the left and right pedals of the rider are completely consistent when driving in a straight line. This is an obvious opinion. Therefore, the rider needs to constantly adjust the stroke of the left and right pedals, and the constant micro-adjustment, the operating experience becomes worse.

In addition, to ensure the stability of the self-balancing car during the start and stop of the self-balancing car, many vehicles have not mentioned the solution of automatic control, so a self-balancing car is needed, and its control mechanism can not only adjust the steering of the self-balancing car, but also control Stability of self-balancing vehicles in start-stop and non-use.

Utility model content

In order to solve the problems of the prior art, the utility model designs a steering mechanism with independent steering control, and can realize the self-balancing vehicle to keep stable when the self-balancing vehicle is started, stopped and not in use.

A self-balancing vehicle comprises a main body of the balancing vehicle. A steering wheel is arranged on the pedal surface of the main body of the balancing vehicle. Guard plates are installed above the wheels on both sides of the main body of the balancing vehicle. Support rods are arranged on the left and right sides of the guard plate.

As a preference: the steering wheel is hidden in the cavity of the tread surface through the lifting mechanism. Realize that when the user steps on the self-balancing vehicle and is stepped on, the bottom surface of the foot will contact with the same contact surface as the pedal surface.

As a preference: the lifting mechanism of the steering wheel is a heart type self-locking elastic push rod or an electric linear push rod or a lead screw. When the self-balancing car is not in use, it can be raised above the tread surface by the lifting mechanism to realize the parking command; when the user steps on the self-balancing car, it is pressed to realize the starting command.

As a preference: the steering wheel is composed of a resistor body and a movable brush. Rotation of the steering wheel by footsteps produces a variable signal that can be read by the controller to identify the degree of rotation reversal.

As a preference: the contact between the support rod and the ground is controlled by the motor rotation shaft or the electric linear push rod.

To sum up, the beneficial effects of the utility model are: the self-balancing car designed by the patented technology adopts the foot pedal to drive the rotating steering wheel to change the driving direction of the self-balancing car, and the swing rod in the prior art is combined with The steering function is separated to solve the defects of poor adaptability and easy misoperation of the existing swing lever. The swing bar of the self-balancing vehicle is only responsible for the safety function that the rider can rely on. Foot-operated steering wheel, easy to operate, can be applied to self-balancing vehicles with or without rods, and can also play a start and stop command effect, and further control the support rod through the contact state of the steering wheel and the rider Waiting for the triggering of the parking mechanism used for parking, the effect can serve multiple purposes.

detailed description

As shown in Figure 1: a self-balancing car, including a self-balancing car main body 10, when the wheels 12 on both sides of the self-balancing car main body 10 have a driver standing on the self-balancing car main body 10, the battery pack, sensors, Under the control of mechanisms such as the control unit, the upright traveling state is maintained. The pedal surface of the self-balancing vehicle body 10 is provided with a steering wheel 40, which can be hidden in the cavity 41 of the tread surface, and the upper surface of the steering wheel 40 is flush with the tread surface. The steering wheel 40 is composed of a resistor body and movable brushes. The specific structure is similar to the internal structure of the potentiometer. The steering wheel 40 generates a variable signal after being rotated by the driver's foot static friction contact, and the signal can be read by the control unit to identify the degree of rotation of the steering wheel 40 in the opposite direction. The steering wheel 40 does not need to return to a fixed position after each use, and the control unit can read the initial rotation angle before the movement as a variable zero point, and the left-handed and right-handed angles can be positive or negative according to the signal relative to the adjustable zero point value judgments. In this technology, the handle bar 11 installed on the main body 10 of the self-balancing vehicle only needs to play the role of stably supporting the driver, and the safety and stability factor is greatly improved. The present invention solves the defects of poor use adaptability and easy misoperation of the existing swing rod.
