Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
For a motor drive controller for electric vehicle system, this motor drive controller comprises radiator 1, controller PCB plate 2, moulds shell cover 3, sealing ring 4, packing ring 5, multiple second binding post 62 and multiple first binding posts 61 etc.Radiator 1 is the heat radiation of system and the installation of components and parts, provides good carrier.The circuit part of the integrated whole controller of controller PCB plate 2.The effect of moulding shell cover 3 mainly protects whole system jointly with radiator 1, reduces the unfavorable factor such as vibrations, dust storm, liquid in the process of moving and, on the impact of whole system, and is provided as the carrier of external information alternating current devices.High temperature resistant, fire-retardant sealing ring 4 in use, embeds and moulds in the groove of shell cover 3, by the connection of screw, cause sealing ring 4 to compress, thus ensures the high-protection level moulding shell cover 3 and radiator 1; In addition the use of shell cover 3 is moulded, can insulation distance between reduction of device and housing, reduce the size of whole product.High temperature resistant, fire-retardant packing ring 5 be by with the assembly deflections moulding shell cover 3, ensure binding post and mould insulation between shell, heatproof, fire-retardant, sealing effectiveness.Second binding post 62 and multiple first binding post 61, as standard fitting, solve input, the signal transmission exported and Receiver Problem.
Controller PCB plate 2 all will be arranged on radiator 1, then will mould shell cover 3 and be placed on radiator 1, lock-screw, and waterproof and dustproof, anti-foreign impacts power are strong, convenient for installation and maintenance.
Concrete, as shown in Figures 1 to 6, a kind of motor drive controller for electric vehicle system, it comprises radiator 1, controller PCB plate 2, moulds shell cover 3, sealing ring 4; Mould shell cover 3 be open at one end and be provided with the housing of holding tank 31, the bottom of this holding tank 31 is provided with multiple first wiring hole 32, and the sidewall of this holding tank 31 is provided with multiple second wiring hole 33; Radiator 1 is sealedly connected on the open-mouth moulding shell cover 3, and is tightly connected; Preferably, mould screw between shell cover 3 with radiator 1 to be connected.Controller PCB plate 2 is arranged on radiator 1, and is placed in holding tank 31; Controller PCB plate 2 is provided with multiple second binding post 62 and multiple first binding post 61, first binding post 61 and the first wiring hole 32 one_to_one corresponding, and the first wiring hole 32 is stretched out in one end of the first binding post 61; Second binding post 62 and the second wiring hole 33 one_to_one corresponding, the second binding post 62 is corresponding with the second wiring hole 33, and the second wiring hole 33 is stretched out in one end of the second binding post 62; Mould between shell cover 3 and radiator 1 and be provided with sealing ring 4.
Further: mould shell cover 3 and be provided with annular groove 34 near the side of radiator 1, sealing ring 4 is arranged in annular groove 34.
Further: between the first binding post 61 and the first wiring hole 32, to be provided with packing ring 5.
The beneficial effects of the utility model are: structure is simple, good heat dissipation effect, and degree of protection is high, be convenient to I&M, be particularly suitable for identical product, different capacity section expansion with derivative, not only shorten product development cycle, the versatility of internal components, is also convenient to cost control simultaneously.Radiator 1 directly uses flat radiator 1, selection, easy to process, according to different power, can increase thickness or the change overall dimension of radiator 1, solve heat dissipation problem.Mould the use of shell cover 3, sealing ring 4, packing ring 5, well solve the impact of environmental factor such as isolation environmental liquids, dust etc., guarantee performance and the life-span of motor drive controller.
