Description

Power control system of electric scooter

Technical Field

The utility model relates to a power control system of an electric scooter, which is mainly applied to the technical field of electric scooters.

Background

The electric bicycle is a very popular transportation means at present, not only can people conveniently move, but also can not produce any waste gas such as carbon dioxide and the like during movement, and has the effects of energy conservation and environmental protection, and therefore, the electric bicycle is gradually the first choice of many people as a walking tool.

The electric bicycle is a traffic tool taking a battery unit as a power source, and has the same structure as a common bicycle, and the difference is that the electric bicycle is provided with a battery unit and a motor electrically connected with the battery unit as driving power, and the motor takes the electric power of the battery unit as the power source and drives wheels of the electric bicycle to rotate so as to drive the electric bicycle to move.

The prior electric bicycle is characterized in that a motor is firstly arranged on a frame and connected by a chain, a front or rear hub motor of the motor is arranged in a hub of a front wheel or a rear wheel, and a hub motor of the motor is arranged beside the hub. However, there are many disadvantages in the arrangement of the motor, in which, firstly, the center of gravity of the vehicle body is concentrated at the front part of the vehicle body or at the rear part of the vehicle body, and the position of the center of gravity will reduce the balance of the vehicle body, thereby affecting the riding stability; secondly, since the front hub motor is disposed on a front wheel and the rear hub motor is disposed on a rear wheel, such an arrangement will increase the difficulty of maintenance during maintenance of the front wheel or the rear wheel.

To solve the above-mentioned drawbacks, the prior art moves the motor to the middle part of the vehicle body so that the center of gravity can be shifted from the front part or the rear part of the vehicle body to the middle part of the vehicle body, and the motor may be generally referred to as a center motor. The center motor must have a low rotational speed and a high torque output to meet the riding requirements of the vehicle body. Therefore, in order to obtain the low rotation speed and the high torque power source output, the middle motor needs to be additionally provided with a planetary reducer with a low reduction ratio so as to achieve the low rotation speed and the high torque power source output.

However, the speed reduction ratio of the planetary reducer is low, so that the rotation speed of the central motor cannot be greatly reduced and the torsion of the central motor cannot be greatly improved. Therefore, if the power source output of the low rotation speed and the high torque is to be achieved, a motor with a middle and low rotation speed and a middle and high torque is required to meet the output requirement of the low rotation speed and the high torque required by riding. However, compared with a motor with high rotation speed and low torsion, the motor with medium and low rotation speed and medium and high torsion has the defects of large volume, heavy weight, high cost and the like. Although the middle motor is large and heavy, the middle motor can be suitable for common bicycles, but is suitable for a scooter for children to learn and train riding technology, because the size of the scooter is smaller, if the traditional middle motor is used, the size of the middle motor is relatively larger, the weight of the middle motor is heavy, and the small body of the child cannot be loaded.

Moreover, in many electric vehicles (such as electric scooter or electric scooter) used by young children, the effect of speed control is achieved by rotating the grip, however, no matter what driving method is adopted, a certain coordination and reaction force are required in control once the travelling speed is adopted, so that each user cannot be satisfied, in addition, once the sudden situation is met, the user often cannot take a reaction in real time, the danger in use is increased in an intangible way, and further improvement is required.
