The power line 103 passes under the reinforcement 106 and extends toward the motor 102 so as to bypass the reinforcement 106.

JP 2000-92616 A

  By the way, when the power line 103 is provided so as to bypass the reinforcement 106, a space is required between the battery 101 and the reinforcement 106 for bending the power line 103 when arranging the power line 103. By securing this space, the mounting space for the battery 101 may be reduced.

  An object of the present invention is to provide a vehicle capable of widening a battery mounting space.

  A vehicle that solves the above problems is connected to a motor and a battery that is a drive source of the motor, and extends along the outer surface of the bottom of the vehicle body toward the motor, and the reinforcement provided on the outer surface of the bottom. The vehicle travels by driving the motor, and an insertion portion through which the power line passes is defined by the outer surface of the bottom portion and the reinforcement.

  According to this, the power line can be passed through the outer surface of the bottom portion of the vehicle body and the insertion portion defined by the reinforcement. For this reason, it is not necessary to bypass the reinforcement and provide a power line, and it is not necessary to provide a space for bending the power line between the battery and the reinforcement. For this reason, the space for mounting the battery can be widened as much as there is no space for bending the power line.

  In the vehicle, the reinforcement is preferably fastened and fixed to the bottom portion. According to this, the reinforcement can be fixed to the bottom after the power line is installed at a predetermined position of the vehicle body. When the power line is installed after fixing the reinforcement, it is necessary to secure a large insertion portion in order to pass the power line through the insertion portion. For this reason, a reinforcement will be weakened compared with the case where a reinforcement is fixed to a bottom part after installing a power line. By fixing the reinforcement to the bottom after installing the power line, the insertion portion can be made smaller than when the reinforcement is fixed first, and thus weakening of the reinforcement can be suppressed.

About the said vehicle, it is preferable that the said reinforcement has a recessed part which divides the said insertion part. According to this, a recessed part is easy to provide compared with the case where a recessed part is provided in the bottom part of a vehicle body.
With respect to the vehicle, it is preferable that the recess is provided with a reinforcing member provided so as to overlap the recess, and the recess and the reinforcing member are integrally fixed to the bottom. According to this, reinforcement can be reinforced.

  According to the present invention, the battery mounting space can be widened.

As a result, the harness cover 81 is fixed to the bottom 22 of the vehicle body 21. The harness cover 81 is provided on the opposite side to the battery 13 across the reinforcement 31, that is, between the reinforcement 31 and the storage chamber 12. A part of the harness cover 81 protrudes into the second recess 48 (inside the reinforcing member 54).

  As shown in FIGS. 6A and 7, in a state where the reinforcement 31 is attached to the bottom portion 22 of the vehicle body 21, the insertion portion 90 is defined by the reinforcement 31 and the outer surface 24 of the bottom portion 22. Specifically, in the reinforcement 31, the first wall portions 42 and 62, the second wall portions 43 and 63, the base portions 44 and 64, the non-contact portions that are not in contact with the outer surface 24 of the bottom portion 22, An insertion portion 90 is defined between the first concave portion 47 and the second concave portion 48 and the outer surface 24 of the bottom portion 22. The insertion portion 90 passes through the reinforcement 31 in the length direction of the vehicle 10. The power line 28 extending from the vehicle body side connector 29 passes through the insertion portion 90. The power line 28 that has passed through the insertion portion 90 extends to the accommodation chamber 12 through a region defined between the harness cover 81 and the bottom portion 22 of the vehicle body 21.

  At the time of manufacturing the vehicle 10, when the above-described reinforcement 31 is fixed, the power line 28 is routed (routed), and after the power line 28 is installed at a predetermined position, the power line 28 enters the insertion portion 90. The reinforcement 31 is fastened and fixed by the stud bolt 32.

Next, the effect | action of the vehicle 10 of this embodiment is demonstrated.
As shown by a two-dot chain line in FIG. 6B, when the power line 28 is provided so as to bypass the reinforcement 31, a space for bending the power line 28 is required when the power line 28 is routed. Further, the power line 28 is exposed to the outside of the reinforcement 31.

  As shown in FIG. 6A, in the present embodiment, the power line 28 passes through the insertion portion 90 defined between the reinforcement 31 and the bottom portion 22. For this reason, it is not necessary to bend the power line 28 extending from the vehicle body side connector 29 in order to bypass the reinforcement 31, and it is not necessary to provide a space for bending the power line 28. For this reason, the battery 13 can be disposed close to the reinforcement 31. In the present embodiment, as shown in FIG. 6B, the battery 13 has a length L when the power line 28 is passed through the insertion portion 90 rather than when the power line 28 is provided by bypassing the reinforcement 31. Is approaching.

  Further, when the power line 28 is provided by bypassing the reinforcement 31, the power line 28 is provided in a state of being exposed to the outside. Therefore, it is necessary to provide a cover that protects the power line 28 so as to cover a portion that bypasses the reinforcement 31. There is. That is, the harness cover 81 in the embodiment is enlarged and the power line 28 that bypasses the reinforcement 31 is covered, or the cover that covers the power line 28 that bypasses the reinforcement 31 is added to the harness cover 81 in the embodiment. It is necessary to provide it.

  In the present embodiment, since the power line 28 passes through the insertion portion 90 defined by the reinforcement 31 and the bottom portion 22, a part of the power line 28 is covered with the reinforcement 31. For this reason, since the reinforcement 31 functions as a cover for protecting the power line 28, it is not necessary to provide a cover at a portion where the reinforcement 31 is provided.

Therefore, according to the above embodiment, the following effects can be obtained.
(1) Since the power line 28 passes through the insertion portion 90 defined by the outer surface 24 of the bottom 22 of the vehicle body 21 and the reinforcement 31, it is not necessary to bypass the reinforcement 31 in order to extend the power line 28 toward the motor 11. For this reason, it is not necessary to bend the power line 28 in order to bypass the reinforcement 31. Since it is not necessary to secure a space for bending the power line 28 between the battery 13 and the reinforcement 31, the battery 13 can be brought closer to the reinforcement 31 as much as there is no space for bending the power line 28. . That is, the battery housing part 23 can be widened. Therefore, even a large-capacity battery 13 can be mounted on the vehicle 10 and the cruising distance of the vehicle 10 can be increased.

  (2) Further, the power line 28 can be protected by the reinforcement 31 by passing the power line 28 through the insertion portion 90. For this reason, it is not necessary to provide a cover for protecting the reinforcement 31 in the portion where the reinforcement 31 is provided, and the number of parts is reduced.

  (3) The reinforcement 31 is fastened and fixed by the stud bolt 32 and the nut 33. For this reason, the reinforcement 31 can be fixed after the connection harness 27 is routed. When the power line 28 is routed after fixing the reinforcement 31, it is necessary to enlarge the insertion portion 90 in order to pass the power line 28 through the insertion portion 90. If the insertion part 90 becomes large, the reinforcement 31 will be weakened. By fixing the reinforcement 31 after the power line 28 is routed, the size of the insertion portion 90 can be reduced as compared with the case where the power line 28 is routed after the reinforcement 31 is fixed. For this reason, the weakening of the reinforcement 31 is suppressed. Further, when the power line 28 is routed after fixing the reinforcement 31, it is troublesome to insert the power line 28 through the insertion portion 90, but by fixing the reinforcement 31 after the power line 28 is routed, The power line 28 can be easily handled.

  (4) The insertion portion 90 is partitioned by the first recess 47 and the second recess 48 provided in the reinforcement 31. For this reason, compared with the case where the recessed part for partitioning the insertion part 90 is provided in the vehicle body 21, the insertion part 90 is easy to partition.

  (5) A reinforcing member 54 is provided in the first recess 47 and the second recess 48. By providing the first recess 47 and the second recess 48, the rigidity of the reinforcement 31 is lowered. However, by providing the reinforcing member 54, the rigidity of the reinforcement 31 can be supplemented and the reinforcement 31 can be reinforced. it can.

In addition, you may change embodiment as follows.
The reinforcement 31 may be fixed in a manner different from the fastening and fixing. For example, it may be fixed by welding or the like.

The reinforcement 31 may be fastened and fixed by screwing a bolt inserted through the reinforcement 31 toward the bottom 22 of the vehicle 10 into the bottom 22 of the vehicle 10.
In the embodiment, the first recess 47 and the second recess 48 are provided in the reinforcement 31 so that the insertion portion 90 is defined when the reinforcement 31 is fixed to the bottom portion 22. You may provide the recessed part dented toward the compartment side. In this case, even if the recess 31 is not provided with the recess 31, the insertion portion 90 is defined between the reinforcement 31 and the bottom 22 by the recess provided in the bottom 22.

The insertion portion 90 may be defined by only the first recess 47 and the second recess 48 without providing the reinforcing member 54.
The power line 28 may be routed after the reinforcement 31 is fixed. In this case, the power line 28 can be easily routed by increasing the interval between the reinforcement 31 and the battery 13.

The reinforcement 31 may be a single member. Further, the reinforcement 31 may be one in which three or more constituent members are connected.
The reinforcement 31 may have any shape as long as it is provided so as to protrude from the bottom 22 of the vehicle 10.

  The shape of the harness cover 81 may be any shape as long as a region in which the power line 28 can be passed between the harness cover 81 and the bottom portion 22 can be defined. Further, part of the harness cover 81 may not protrude into the second recess 48.

The reinforcing member 54 may be fixed integrally with the first component member 41 only by welding, or may be fixed integrally with the first component member 41 only by fastening together with the stud bolt 32.
