ッテリフレームとの間に格納するようにしている。2. Description of the Related Art In an electric vehicle, an on-vehicle battery occupies a considerable weight and a mounting space. Therefore, as shown in, for example, Japanese Unexamined Patent Publication (Kokai) No. 52-35023, the load of a plurality of batteries is conventionally used. A battery frame with a dedicated rigid structure is formed to fully withstand the battery, and the upper surface of this battery frame is joined to the lower surface of the floor panel by fastening it with bolts and nuts to the lower surface of the floor member. Are stored between these floor panels and the battery frame.

仲々難しい。As described above, the battery frame has its upper surface overlapped with the lower surface of the floor member and is fastened and fixed in the vertical direction by bolts and nuts. As a result, the battery frame tends to inwardly deform, and even if a sealing material is interposed between the battery frame upper surface and the floor member lower surface, the sealing reaction force of this sealing material cannot be sufficiently obtained. Therefore, it is difficult to secure sufficient sealing function.

る。According to a first aspect of the present invention, an upper surface of a battery frame having a plurality of batteries mounted thereon is
In the structure in which the lower surface of the floor member joined to the lower surface of the floor panel is fastened and fixed in the vertical direction via a sealing material,
A flange is provided upright on the inner peripheral edge and the outer peripheral edge of the upper surface of the battery frame to form a member fitting groove, and the outer peripheral edge flange is slanted outwardly while the outer wall of the floor member is formed on the outer peripheral edge. Inclination molding is performed according to the inclination of the flange, the member fitting groove is externally fitted to the floor member, and a sealing material is sandwiched between the member fitting groove and the floor member to fasten and fix the battery frame to the floor member. I am doing it.

A fitting portion that is externally fitted to the flange engaging portion is formed on the lower peripheral edge of the cover, and the fitting portion is externally fitted to the flange engaging portion of the seal material that is externally fitted to the inner peripheral edge flange, and the battery A cover is attached to the battery frame. According to the third aspect of the present invention, the battery cover is fixed to the floor member in advance by superimposing the side surface of the fitting portion at the lower peripheral edge thereof on the inner wall of the floor member.

を高めてシール性を確保する。According to the present invention, when the battery frame tends to fall inward due to the load of the plurality of batteries, the outer peripheral side flange forming the outer peripheral wall of the member fitting groove of the battery frame is located outside the floor member. It tends to come into pressure contact with the wall, and enhances the sealing reaction force of the sealing material interposed between them to secure the sealing property.

水侵入を防止することができる。According to the second aspect, even if water permeates into the fitting portion between the member fitting groove and the floor member, the flange engaging portion of the sealing material rises and the inner peripheral edge of the upper surface of the battery frame. Since it fits on the flange and the fitting part of the battery cover fits on the outside of the flange, water will not penetrate through these fitting parts to prevent water from entering the battery frame. it can.

Is fixed to the floor member 2 in advance, the battery 1
When it becomes necessary to replace 7, the battery frame 11
It suffices if the battery 17 is detached from the floor member 2 and the battery 17 is attached and detached. Since the attachment and detachment of the battery 17 does not involve the attachment and detachment work of the battery cover 19, which is relatively large, workability can be improved.

As for the inner peripheral portion of the fitting portion with, the flange engaging portion 26 of the sealing material 25 rises and fits into the inner peripheral edge flange 23, and the fitting portion 27 of the battery cover 19 fits outside thereof. Therefore, even if water enters between the bottom surface of the floor member 2 and the top surface of the battery frame 11, the inner peripheral edge flange 23, the flange engaging portion 26, and the fitting portion 27 are crossed over. Although water can be prevented from entering the battery frame 11, the inner peripheral edge flange 23 comes into pressure contact with the inner peripheral wall of the fitting portion 27 when the battery frame 11 tends to fall inward as described above. , And acts to increase the seal reaction force by pressing the seal member 25 between them.

Even if the battery frame tends to fall inward, the sealing material is tightened between the outer peripheral edge flange of the member fitting groove that is inclined outward and the inclined outer wall of the floor member to increase the seal reaction force, Since a seal line having a high seal reaction force is formed on the outer peripheral portion of the fitting portion between the floor member and the member fitting groove, sufficient sealing performance can be ensured.

の侵入防止を徹底することができる。(2) The flange engaging portion formed on the inner peripheral side of the seal member rises to fit on the inner peripheral edge flange of the member fitting groove, and the fitting portion of the battery cover fits on the outer side thereof. Therefore, even if water invades between the bottom surface of the floor member and the top surface of the battery frame, the water may get over the fitting portion between the inner peripheral edge flange and the flange engaging portion and the fitting portion. Instead, it is possible to thoroughly prevent water from entering the battery frame.

ができる。(3) Since the battery cover is fixed to the floor member in advance, when the battery frame tends to fall inward, the inner peripheral flange of the member fitting groove and the inner peripheral wall of the fitting portion of the battery cover are separated. Since the sealing material is tightened to increase the sealing reaction force, a double sealing line with a high sealing reaction force can be formed on the outer peripheral side and the inner peripheral side of the fitting portion between the floor member and the member fitting groove. It is possible to improve the sealing property.

作業性を著しく改善することができる。(4) Since the battery cover is fixed to the floor member, the workability can be remarkably improved without attaching and removing the large battery cover when the battery is attached and detached when the battery is replaced.

はない。(5) Even if the member fitting groove is formed on the upper surface of the battery frame, the outer peripheral edge flange is inclined outward, while the outer wall of the floor member is aligned with the inclination of the outer peripheral edge flange. Since the floor member and the member fitting groove are formed to be slanted, they can be smoothly fitted by the guide action of these inclined surfaces, which may cause a slight inconvenience in the fastening work between the floor member and the battery frame. There is no.
