The PCB board of this scheme adopts the multiple spot installation fixed, and the torus middle part is the double-screw bolt of the card post of protrusion PCB board or fixable screw.
Preferably, the transmission mounting surface is a strip-shaped annular surface arranged along the outline of the base plate body, a mounting boss is arranged on the second side surface of the base plate body, and the mounting boss is positioned on the inner side of the transmission mounting surface.
Preferably, the substrate body is integrally formed.
Originally between motor and the derailleur just need be connected, there is the installation face of mutually supporting between the two, in this scheme, set up the ECU base plate between motor and derailleur, two sides of base plate body, one cooperates with the motor, one cooperates with the derailleur, rational utilization installation space, wherein the first side of base plate body is except motor installation face, the bottom is space in addition, this scheme has set up convex mounting groove, can be used to place electronic control element, the derailleur installation face of the second side of base plate body is cyclic annular and derailleur fixed, inside PCB board installation stationary plane that then can set up of derailleur installation face, utilize the space in the derailleur, the base plate body is located the inside boss that can set up inside protrusion of derailleur of cyclic annular derailleur installation face, the PCB board can be fixed on the boss.
Compared with the prior art, the beneficial effects of the utility model are that: place in between motor and the derailleur in, improve the integrated level greatly, rational in infrastructure, cancellation sheet metal shell makes weight reduction, and the interface integrated level improves, and the cost reduces by a wide margin, reduces the space that ECU accounts for the automobile body simultaneously.
