7が必要となり箱枠の重量が増加する。In such a conventional mounting structure for a vehicle transformer, since a tensile force due to the weight of the transformer 8 is applied to the mounting bolt 9 for mounting the transformer, the mounting bolt having a large strength is used. In addition, when mounting the transformer 8 on the frame 7, it is necessary to support the weight of the transformer 8 from below until the tightening bolts 9 are completely tightened. Furthermore, the frame 7 that serves to suspend the transformer 8 is required, and the weight of the box frame increases.

う。In order to achieve the above-mentioned object, the present invention is a vehicle transformer mounting structure which is suspended and mounted under the floor of an electric vehicle, in which a box frame is constructed under the floor of the electric vehicle. Mount the main frame and tighten the iron core of the transformer to form an iron core clamp with a length larger than the outer width of the coil wound around the iron core, and attach both ends of the iron core clamp to the main frame. I shall. In this case, the iron core tightening fitting and the main frame are attached with bolts.

Since it is mounted directly on the transformer, the transformer mounting bolt is not subjected to tensile force due to the weight of the transformer. Also, when installing the transformer, it is not necessary to support the transformer from below.

In FIGS. 1 and 2, the length C of the iron core tightening metal fitting 10 for tightening the iron core 1 around which the wire ring 2 is wound is made longer than the outer width dimension D of the wire ring 2 by the amount necessary for mounting the transformer. There is a mounting hole 4 in this portion. The iron core tightening metal fitting 10 is a metal piece having an L-shaped cross section, and is composed of a portion for tightening the iron core and a portion attached to the main frame 6 forming the box frame.

ムが不要となるのでその分だけ重量を軽減できる。According to the present invention, since a tensile force is not applied to the mounting bolt for mounting the transformer, the mounting bolt can be made small. Further, when the transformer is mounted on the main frame, it is not necessary to support the transformer from below until the mounting bolts are completely tightened, which improves the workability of mounting. Further, since the frame used for suspending the transformer used conventionally is not required, the weight can be reduced accordingly.
