Abstract
The utility model relates to an electronic power-assisted steering controller which comprises a controller body, an encapsulation body and a heat dissipation body, wherein the encapsulation body comprises an upper cover plate, a shell and a lower cover plate, and is characterized in that the controller body comprises a mainboard and a power amplifier board which can be separated from each other; the mainboard is closely combined with the heat dissipation body; the heat dissipation body is provided with radiating fins; and a gap is arranged between the power amplifier board and the heat dissipation body. The electronic power-assisted steering controller is good in performances of encapsulation and heat dissipation, and light in weight. The electronic power-assisted steering controller is applicable to encapsulating multiple electronic power-assisted steering, and is especially applicable to the electronic power-assisted steering controller of a high-power alternating current (AC) motor.
Description
Technical field
The utility model relates to a kind of electronic power assist steering controller, especially relates to a kind of electronic power assist steering controller that is applicable to high-power AC motor.
Background technology
Along with the fast development of economy and the exhaustion day by day of world energy sources, energy-conservation and environmental protection is paid attention to by people gradually.The breakthrough of electronic power assist steering control technology makes and adopts electronic power assist steering to replace the traditional mechanical power-assisted steering to become a reality.The electronic power assist steering controller is controlled as power-assisted steering of new generation, advantage such as have efficient low-consume, energy-conserving and environment-protective, response is fast, the life-span is long.But the electronic power assist steering controller time can produce a lot of heats in work, if these heats can not in time distribute, can influence electronic power assist steering controller useful life.Therefore, solve heat dissipation problem and become one of technology of most critical in the great-power electronic booster steering controller technology.At present, the electronic power assist steering controller encapsulates some and adopts die casting aluminium, such encapsulation inner space sealing, and also narrow and small, can not form effective cross-ventilation, can only outwards dispel the heat by shell, radiating efficiency is low; Also have some electronic power assist steering controller encapsulation to adopt the shell that has fin, heat dispersion increases, but inside also lacks cross-ventilation, thereby radiating efficiency is still not good enough; For rising to radiating efficiency, adopt the mode that enlarges cooling surface area usually, promptly adopt to enlarge fin, but this can increase raw materials consumption, increase case weight.
The utility model content
The purpose of this utility model is to provide a kind of perfect heat-dissipating, and is in light weight, electronic power assist steering controller encapsulation safe in utilization.
The technical solution of the utility model provides a kind of electronic power assist steering controller, comprise controller body, encapsulation main body and heat radiator body, encapsulation main body comprises upper cover plate, shell and lower cover again, it is characterized in that, the controller body comprises mainboard and power amplifier board, and mainboard and power amplifier board are separable, and mainboard and heat radiator body are combined closely, heat radiator body is provided with radiating fin, leaves the space between power amplifier board and the radiator body.
Below be further improved preferred version:
The height of described radiating fin is 20mm, and thickness is 3mm.
Described lower cover adopts the buckle-type connected mode to be connected with shell.
Described upper cover plate adopts screw and shell to fix.
The beneficial effects of the utility model:
The utility model perfect heat-dissipating, in light weight, safe in utilization; The mainboard and the power amplifier board of controller are separated, increase circulation of air, improve heat-sinking capability; There is radiating fin the radiator body outside, and the height of radiating fin is 20mm, and thickness is 3mm, is convenient to withdrawing pattern technology, has both helped guaranteeing radiating efficiency preferably, makes package surface have self-cleaning ability preferably again; Encapsulation main body is made of shell, upper cover plate, lower cover three parts, makes the controller overall volume reduce, and increases attractive in appearancely, but does not influence whole radiating effect; Lower cover adopts the mode of buckle to be connected with shell, and mounting means is easy, is easy to dismounting; Upper cover plate adopts screw to fix with shell and fixes, and does not need the integral disassembly, assembly controller during debugging, opens upper cover plate and can debug and keep in repair.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing: comprise controller body, encapsulation main body and heat radiator body, encapsulation main body comprises upper cover plate, shell and lower cover again, it is characterized in that, the controller body comprises mainboard and power amplifier board, mainboard and power amplifier board are separable, mainboard and heat radiator body are combined closely, and heat radiator body is provided with radiating fin, leave the space between power amplifier board and the radiator body.The height of described radiating fin is 20mm, and thickness is 3mm.Described lower cover adopts the buckle-type connected mode to be connected with shell.Described upper cover plate adopts screw and shell to fix.
Encapsulation main body is inner, and by three convexes with controller mainboard, power amplifier board separately there is the space of 10mm the centre, is beneficial to air flows, strengthens radiating effect.When temperature contrast being arranged everywhere in the space of two planks, internal air pressure is different, makes to produce free convection in the space, thereby heat is taken out of fast, further improves heat dispersion.The high 20mm of radiating fin, arranged direction has considered that fully controller is arranged in the air flows situation in the driver's cabin; Radiating fin wall thickness 3mm is convenient to withdrawing pattern technology.Radiator body and mainboard are fixed by screw, make it to connect as one, and have increased whole radiating effect and attractive in appearance.Lower cover adopts the buckle-type connected mode to be connected with shell, is convenient to assembly and disassembly.
