Power-driven four-wheeler controller

Abstract

The invention discloses a power-driven four-wheeler controller, comprising a bottom board, a heat dissipating shell, a sealing gasket, a plastic cover cap, bolts, threaded supporting columns I. threaded supporting columns II, a functional plug, a master cable binding post, a capacitor and power tubes, wherein the middle of the power-driven four-wheeler controller is provided with the hollow heat dissipating shell; the bottom board is a thick aluminum plate; the plastic cover cap is arranged at the top of the power-driven four-wheeler controller; a PCB plate I, a PCB plate II and an aluminum substrate are installed in the hollow heat dissipating shell. The 48 power tubes and 10 threaded supporting columns II are welded on the aluminum substrate tightly; the threaded supporting columns II are used to lock the aluminum substrate on the bottom board and are connected with the PCB II simultaneously; one sealing gasket is arranged between the functional plug and the plastic cover cap. The controller of the invention improves assembling efficiency and removes a hidden danger that the power tubes are burned because of heat concentration. The power-driven four-wheeler controller avoids the condition that the impedance is increased because of insufficient solder and function of the controller is lost because of high heat.

Description

technical field [0001] The invention relates to a controller for a 4KW electric vehicle, which belongs to electric vehicles, in particular to a controller for an electric four-wheel vehicle. Background technique [0002] With the development of society and the continuous increase of fuel vehicles, the shortage of natural resources such as petroleum fuels and the global warming caused by fuel emissions have become increasingly prominent. Therefore, in this context, hybrid or pure power vehicles have gradually entered people's lives, and electric vehicles have emerged as the times require. Among them, electric four-wheel vehicles have gradually become the main vehicles for picking up children and walking for the elderly due to their simple driving operability, safety and comfort, and environmental protection and pollution-free. The controller is the core component of the electric vehicle. It controls the electric current of the motor to ensure the power required for the vehic...

Problems solved by technology

[0003] The self-weight of the electric four-wheel vehicle is much larger than that of the two-wheel vehicle, and the speed is fast, and the load is relatively large. However, the power tubes in the controller of this structure are distributed in a single row, and the heat generated by the power tubes is too concentrated during operation. When the heat-conducting aluminum strip conducts to the heat-dissipating shell of the aluminum profile, the heat-conducting path is too long, and the heat-dissipating effect is poor. If the 4KW motor used in the electric four-wheel vehicle is matched, the power tube will often burn out and fail because the heat cannot be effectively exported in time. Loss of controller function
