Description
Technical field
The utility model relates to the elec. vehicle engine installation, particularly the air-cooled controller of battery-driven car alternating current dynamo.
Background technology
AC driving progressively replacing direct drive and the constant speed that is applied to blower fan, water pump drags and the speed-adjusting driving system of electric locomotive, electronlmobil among.Wherein permagnetic synchronous motor, threephase asynchronous machine and switched reluctance machines are three kinds of alternating current dynamos that are most widely used.In electric automobiles, electric machine controller will move towards industrialization as a kind of product.Compactness rational in infrastructure, quick for installation, fundamental prerequisite that debugging is convenient, the safety performance height is following electric machine controller should possess also are most important character.Under condition with equipower, can make the structure of actuator more reasonable, the requirement that can make actuator satisfy the car driveability has again become the problem that the development of everybody common concern will solve.
Illustrated in figures 1 and 2 is the air-cooled controller electrical structure diagram of battery-driven car AC asynchronous motor of prior art.Comprising fin-inserted radiator 100, casing 101, case lid 103, master control board 102, power model 111,112,113, chemical capacitor 121,122,123,124, current sensor 131,132, main bus-bar plate 141,142, insulcrete 143, absorption circuit 151,152,153, the connection jaws of positive, negative, U phase, V phase, W phase is 161,162,163,164,165, signal socket connector 166.The layout of each components and parts is as shown in Figure 1 and Figure 2: casing 101 is fixing with fin-inserted radiator 100, case lid 103 is installed on the casing 101 again, thereby constitutes the controller case body portion; In inner structure, power model 111,112,113 is installed on the radiator 100, chemical capacitor 121,122,123,124 is by being connected the top that is positioned at power model 111,112,113 with main bus-bar plate 141,142, insulcrete 143 is the isolation layer of main bus-bar plate 141,142, current sensor 131,132 is respectively as the current monitoring device of V, W phase, master board 102 is installed on the casing 101 by sight shield, is arranged in the top of controller inner structure; The connection jaws 161,162,163,164,165 and the signal socket connector 166 of positive, negative, U phase, V phase, W phase are positioned on the casing.
In the above controller architecture components and parts mounting arrangements, there is following shortcoming:
1, the controller case body portion is made up of casing 101 and case lid 103 two parts, tank surface has been installed connection jaws 161,162,163,164,165 and the signal socket connector 166 of positive, negative, U phase, V phase, W phase, need so when mounted casing 101 at first is fixed on the radiator 100, and then carry out the installation of the inner components and parts of controller, add a cover case lid 103 at last.So the inner components and parts of controller be installed in one around carry out in the osed top space, increased the controller mounting hardness; Same when the dismounting of controller, also have a same problem, need earlier the connector wire harness to be disconnected with inner, unload the transfer plug-in unit after, the casing of just dismantling.Because the inner structure of controller is compact, a such structure brings a lot of inconvenience for the Installation and Debugging of controller and the replacing of inner components and parts.
2, because master control board is positioned at the top of each components and parts, so when changing other part, at first master control board will be dismantled.So just increased the dismounting step, also increased the possibility of the improper damage of master control board, and because master control board is installed in the unlimited environment of relative major loop, the electromagnetic distrubance that receives major loop is bigger, might cause the work mal of master control board.
The utility model content
The purpose of this utility model provides the air-cooled controller of a kind of later-model battery-driven car alternating current dynamo, by changing the structure of controller, makes the compactness rational in infrastructure of controller, quick for installation, debugging convenience, and the effectiveness of shielding of the inner master control board of enhancement controller.
The technical solution adopted in the utility model: casing, the case lid of controller are united two into one, what changed controller goes out line position and outlet method, the line position that goes out of controller is positioned on the radiator, inner all device mounting of controller can be carried out under the environment that opens wide all around like this, add a cover casing at last on the basis of the whole installations in inside again; When dismantling controller, the casing of controller is opened, controller inside is unlimited fully, even if like this under the compact situation of controller inner structure, also can install easily, dismantles, inner components and parts of changer controller more.
The air-cooled controller internal modifications of the utility model the mounting means and the position of master control board, master control board is installed in one fully independently in the shielding box, shielding box is fixed on the radiator, has so promptly made things convenient for controller in-to-in structure to install.Strengthened the antijamming capability of master control board again.
The air-cooled controller of the utility model has changed the direct mutually mode from the casing outlet of positive, negative, U phase, V phase, W in the past, has adopted the air plug outlet, has strengthened the degree of protection of controller.
