Anti-slip device for electric sightseeing vehicle

Abstract

An anti-slip device for an electric sightseeing vehicle comprises a switching circuit and a power device. The switching circuit is connected with the power device in series, and the work state of the power device is controlled. The anti-slip device further comprises a control circuit, and the control circuit is connected with the switching circuit and the power device in series. A series excited motor is adopted as the power device, and is provided with a motor exciting winding. The motor exciting winding of the series excited motor is connected with the control circuit in series. The control circuit comprises an armature winding and a brake resistor, and the armature winding is connected with the brake resistor in series. The series excited motor is adopted as the power device, the mechanical characteristic curve of the series excited motor conforms to the running characteristic of the electric vehicle, the dynamic braking technology is developed on the basis, vehicle running safety can be further improved, and the product manufacturing cost can be effectively controlled. Downhill dynamic braking is carried out through the series excited motor, the running safety of the electric vehicle is improved, and meanwhile the material product cost is lowered.

Description

Technical field: [0001] The invention belongs to a braking device for an electric sightseeing car, in particular to an anti-slope device for an electric sightseeing car. Background technique: [0002] Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as energy sources, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed. The first electric car was produced in 1834 and it was driven by a DC motor. Today, electric vehicles have changed dramatically and come in many varieties. [0003] Electric bicycles have been favored by low- and middle-income groups in cities for their cheap, convenient, and environmentally-friendly functional advantages. From the research and development of electric bicycles in China to the market launch in small batches in the mid-1990s, to the production and sales since 2012, ...

AI Technical Summary

Problems solved by technology

[0006] Traditional electric sightseeing cars can use separate excitation or AC motor to achieve energy consumption braking, but the cost of AC system and separate excitation system is high, and the mechanical characteristic curve of separate excitation motor is not suitable for the operating characteristics of electric vehicles

The series excitation motor is used, and the hydraulic system is used to brake when going down a long slope, which not only increases the driver's driving fatigue, but also has certain safety hazards
