Lifting self-discharging mechanism used for full electric vehicle

Abstract

The invention discloses a lifting self-discharging mechanism used for a full electric vehicle. The lifting self-discharging mechanism used for the full electric vehicle is simple in structure, high in efficiency, safe, reliable and suitable for the full electric vehicle. The lifting self-discharging mechanism used for the full electric vehicle comprises a vehicle frame, a cross beam, a motor, a mechanical driving box, a straight spur gear, a sector gear, a compartment, guide rail grooves, sliding blocks and tie bars, wherein the motor and the mechanical driving box are both fixedly installed on the cross beam at the rear of the vehicle frame, the output shaft of the motor is connected to an input shaft of the mechanical driving box, the straight spur gear is installed at one end of an output shaft of the mechanical driving box, and the sector gear is fixedly installed at the rear of a base plate of the compartment. A motive power source of the electric vehicle serves as a power source of a lifting mechanism, after the circuit is turned on, electric energy is converted into mechanical energy through the motor and is transmitted to the mechanical driving box, then the sector gear drives the compartment to rotate clockwise or anti-clockwise, and therefore lifting and reset of the compartment are achieved. The lifting self-discharging mechanism used for the full electric vehicle is easy to implement, enables a lifting process to be stable, can improve the reliability of the entire lifting process and lowers cost.

Description

Technical field [0001] The invention relates to a lifting and self-unloading mechanism, in particular to a lifting and self-unloading mechanism suitable for small-tonnage pure electric dump trucks, and belongs to the field of vehicle engineering. Background technique [0002] With the increasing pressure of environmental protection, the application of electric vehicles has become increasingly widespread. Pure electric dump truck is a new energy special vehicle for short-distance and small-load engineering operations in cities. Compared with the traditional dump truck, its whole vehicle is smaller in size and completely relies on the power battery pack to provide power. It has zero emissions and no pollution. The power is about 50-70kW, the deadweight is usually only 1-2 tons, and the transportation distance is also Relatively short. [0003] At present, most traditional dump trucks use direct push or tie rod combined hydraulic lifting mechanisms. However, this kind of lifting me...

Problems solved by technology

[0004] (1) The structure of the hydraulic lifting mechanism is complex, the energy transmission route is long, and the oil pump, hydraulic cylinder, pipeline and other components are easy to leak

[0005] (2) The hydraulic lifting mechanism contains various precision-manufactured components such as hydraulic oil pumps, oil cylinders, and control valves. These components are expensive to manufacture and expensive

[0006] (3) The energy transmission form of the hydraulic lifting mechanism is: electrical energy—mechanical energy—hydraulic energy—mechanical energy. There are many energy conversion links, long transmission routes, and oil loss along the way, which reduces the overall mechanical transmission efficiency. only about 50%

Therefore, the hydraulic lifting mechanism cannot better solve the requirements of pure electric vehicles with high transmission efficiency, simple structure, and low cost, and there are many technical problems. It is necessary to develop a lifting mechanism directly driven by electric energy to make it run The process is more stable, reliable, efficient, and compact in structure and can reduce power consumption in engineering operations
