According to a fourth invention, in any one of the first to third inventions,
A positioning portion for positioning the end portion of the reinforcing material is provided in the insertion portion inserted into the end portion of the reinforcing material in the joint member.

  According to this configuration, it is possible to suppress displacement of the reinforcing material even if there is a manufacturing error in the reinforcing material.

  According to the first invention, since a plurality of metal reinforcing members are joined by the resin joint member, a plurality of reinforcing members having manufacturing errors can be joined, and a high reinforcing effect can be obtained. .

  According to the second aspect of the invention, since the reinforcing material is joined by the plurality of joint members so as to form an annular shape, a higher reinforcing effect can be easily obtained.

  According to the third invention, since the insertion portion to be inserted into the end portion of the reinforcing material is provided in the joint member, the reinforcing material can be reliably coupled by the joint member.

  According to the fourth invention, since the positioning portion for positioning the end portion of the reinforcing material is provided in the insertion portion of the joint member, it is possible to suppress the displacement of the reinforcing material even if the reinforcing material has a manufacturing error.

Thereby, the battery support member 1 in which the first to seventh lower reinforcement members 11 to 17, the first to fourth upper reinforcement members 21 to 24, and the first to fourth joint members 31 to 34 are insert-molded is obtained. . The stay 3 may be fastened after demolding.

  The support portion 2 of the battery support member 1 is a portion that supports the battery from below, and the first to seventh lower reinforcement members 11 to 17 are disposed on the support portion 2 that directly receives the load of the battery. Therefore, the load of the battery acts on the first to seventh lower reinforcement members 11 to 17 surely, and the reinforcing effect by the first to seventh lower reinforcement members 11 to 17 is sufficiently obtained. Further, since the first to seventh lower reinforcing members 11 to 17 are insert-molded, the first to seventh lower reinforcing members 11 to 17 and the surrounding resin material 40 are firmly integrated and reinforced. The effect is further enhanced. Therefore, the thickness of the resin material 40 can be reduced.

  Moreover, in this embodiment, since the 1st-7th lower side reinforcement materials 11-17 and the 1st-4th upper side reinforcement materials 21-24 are provided so that it may extend in length and breadth, not only the load of an up-down direction For example, it can sufficiently withstand a side impact such as a vehicle collision. Furthermore, since the 1st-4th upper side reinforcement materials 21-24 and the 1st-4th joint members 31-34 are continuing cyclically | annularly, it can also be set as a structure strong against the impact from a side by this. it can.

  As described above, according to this embodiment, the plurality of first to fourth upper reinforcing members 21 to 24 made of metal are coupled by the first to fourth joint members 31 to 34 made of resin. The reinforcing members 21 to 24 having manufacturing errors can be combined and integrated, and a high reinforcing effect can be obtained.

  Moreover, since the 1st-4th upper side reinforcement materials 21-24 were couple | bonded so that the 1st-4th joint members 31-34 may make cyclic | annular form, a higher reinforcement effect can be acquired easily.

  Moreover, since the insertion parts 31a-34a and 31b-34b inserted in the edge part of the 1st-4th upper side reinforcement materials 21-24 were provided in the 1st-4th joint members 31-34, the 1st-4th upper side The reinforcing members 21 to 24 can be reliably coupled by the first to fourth joint members 31 to 34.

  In addition, in the said embodiment, although the case where the 1st-7th lower reinforcement materials 11-17 consist of the member by which extrusion molding was carried out was demonstrated, not only this but the member by which press molding was carried out, It may be made of a resin material having a strength higher than that of the resin material 40.

  Moreover, you may form the hollow parts 31d and 31e (it shows to FIG.14 (c)) in the outer peripheral surface of the insertion parts 31a and 31b like the modification 1 of embodiment shown in FIG. The depression 31d is formed on the upper surface of the upper insertion part 31a, and the depression 31e is formed on the lower surface of the lower insertion part 31a. And the contact surface part 31f as a positioning part is provided in parts other than the hollow part 31d in the outer peripheral surface of the upper insertion part 31a. Also on the outer peripheral surface of the lower insertion portion 31a, a contact surface portion 31g as a positioning portion is provided in a portion other than the recess portion 31d. When the upper and lower insertion portions 31a and 31a are inserted into the end portion of the first upper reinforcing member 21, for example, the contact surface portions 31f and 31g come into contact with the inner peripheral surface of the end portion of the first upper reinforcing member 21, respectively. The end of the reinforcing member 21 can be positioned in the vertical direction and the horizontal direction. At this time, since the depressions 31d and 31e are formed, the surface pressure applied to the contact surface portions 31f and 31g at the time of insertion increases, and the manufacturing error absorbing action of the first upper reinforcing member 21 due to the deformation of the contact surface portions 31f and 31g. Can be increased. In addition, the 2nd-4th joint members 32-34 can be comprised similarly.

  Further, as in Modification 2 of the embodiment shown in FIG. 15, the recesses 31d and 31e may be formed on the outer peripheral surface of the insertion portion 31a, and the protrusions 31h and 31i (positioning portions) may be formed. In addition, the insertion part 31b of the 1st joint member 31 and the 2nd-4th joint members 32-34 can also be comprised similarly. Moreover, you may provide the hollow parts 31d and 31e in the wall surface which opposes, and may provide in both side surfaces.

  The protrusion 31h of Modification 2 is formed so as to protrude upward from a portion other than the formation portion of the recess 31d on the upper surface of the upper insertion portion 31a. Further, the protrusion 31i is formed so as to protrude downward from a portion other than the formation portion of the recess 31e on the lower surface of the lower insertion portion 31a. By forming the protrusions 31h and 31i, manufacturing errors of the first upper reinforcing member 21 can be absorbed by deformation of the protrusions 31h and 31i when inserted. The shape of the positioning portion is not limited to the shape described above, and various shapes that deform when inserted can be used. Moreover, in this modification, insertion force can be reduced and it can be made easy to assemble. Moreover, you may form a recessed part instead of protrusion 31h, 31i.

  In addition, the insertion part 31a, 31b, 32a, 32b, 33a, 33b, 34a, 34b of the 1st-4th joint members 31-34 may be formed in a cylinder shape, and may be formed in a plate shape. .

  The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  As described above, the battery container according to the present invention can accommodate, for example, a battery for running an electric vehicle.
