Description

  The present invention relates to an automobile storage box structure applied to an automobile having a bumper portion.

  A battery unit used in an electric vehicle needs to be charged when the amount of stored electricity decreases. To charge the battery, a charging cord is required. A current sent from an electric supply source (for example, a 100-volt or 200-volt commercial power source) via a charging cord during charging is supplied to the battery unit via a charging device mounted on the vehicle body.

  Two types of charging cords are known: a constant connection type, one end of which is always connected to an electric vehicle, and a separation type, which is connected to a power supply terminal of the electric vehicle only during charging. In the always-connected charging cord, a plug provided at the other end of the charging cord is inserted into a socket of an electric supply source during charging. On the other hand, in the separated type charging cord, plugs are provided at both ends, and at the time of charging, one plug is connected to the power supply terminal of the vehicle body, and the other plug is inserted into the socket of the electric power source.

  There is no risk of losing the always-on type charging cord, but a storage section is required to store a long power cord of several meters or more in the vehicle body. In addition, it is necessary to prevent rainwater from being charged on the stored charging cord or plug. For example, in a charging cord storage structure for a motorcycle disclosed in Patent Document 1 below, a cord box and a plug receiver that can store a charging cord are provided in the vicinity of a pipe that constitutes a vehicle body frame.

Japanese Patent No. 3347433

  The charging cord storage structure for a motorcycle disclosed in Patent Document 1 cannot be applied to a passenger car. In addition, when the charging cord is stored in the vehicle compartment as in a general automobile, there is room for improvement such as causing the vehicle interior to become dirty.

  Accordingly, an object of the present invention is to provide a storage box structure for an automobile that can store stored items such as a charging cord outside the vehicle compartment in a position where it will not rain.

  The automobile storage box structure of the present invention includes a bracket member that is fixed to a vehicle body and has a bumper mounting portion, a box body that is fixed to the bracket member and has a storage port for stored items, and a box body that is attached to the vehicle body and has the box body.

When not charging, the charging cord 60 is stored in the box body 31 and the lid member 34 is closed. The lid member 34 is held so as not to be opened by a holding member 87 (shown in FIG. 1) and is in a locked state.

  As shown in FIG. 2, when the lid member 34 is in the fully closed position, the lid member 34 closes the entrance / exit 55 of the box body 31, and the outer surface of the outer member 80 of the lid member 34 is connected to the outer surface of the bumper body 32. By being substantially flush with each other, the lid member 34 can form a part of the bumper face of the rear bumper portion 12. Further, since the first seal member 56 is in close contact with the inner member 81 of the lid member 34, rainwater or the like is prevented from entering the inside of the box body 31.

  When the charging cord 60 is used for charging, the lid member 34 is unlocked by operating an operating member (not shown) as an opener provided in the vicinity of the driver's seat. Then, the lid member 34 is opened by placing a hand on the recess 86 of the lid member 34. When the lid member 34 moves to the front open position as shown by a two-dot chain line in FIG. 2, the inner member 81 of the lid member 34 assumes a substantially horizontal posture.

  When the lid member 34 is opened, the charging cord 60 can be taken out by opening the loading / unloading port 55 of the box body 31. Thus, the battery unit can be charged by connecting the plug 61 of the charging cord 60 taken out from the box body 31 to a commercial power source or the like.

  The lid member 34 can also be closed while the charging cord 60 is pulled out from the box body 31. In that case, the lid member 34 is closed with the charging cord 60 positioned on the recess 86 of the lid member 34 as shown in FIG. By passing the charging cord 60 through the recess 86 in this way, the charging cord 60 can be positioned in the vehicle width direction by the recess 86, and the charging cord 60 can be prevented from moving excessively.

  Since the second seal member 72 is provided at a position corresponding to the recess 86 in the opening 71 of the bumper main body 32, the second gap between the recess 86 of the closed lid member 34 and the charging cord 60 is second. The sealing member 72 can be sealed. For this reason, it is possible to prevent rainwater or the like from entering the inside of the box body 31 through the charging cord 60 during charging.

  When charging is completed, the charging cord 60 is stored in the box body 31, the lid member 34 is closed, and the lid member 34 is locked by the holding member 87. When the lid member 34 is closed, the lid member 34 closes the entrance / exit 55 of the box body 31 and the first seal member 56 prevents rainwater and the like from entering.

  According to the storage box portion 21 of the present embodiment, equipment such as a charging cord 60 or small luggage can be stored in a position where it does not rain, for example, in the box main body 31 disposed inside the bumper main body 32. . Further, since the charging cord 60 can be handled outside the vehicle body 11, the interior of the vehicle interior is not contaminated by the charging cord 60. In addition, when the lid member 34 is closed, the entrance / exit 55 of the box body 31 is covered by the lid member 34, so that it is possible to avoid rain on the charging cord 60 and the like housed in the box body 31.

  The bumper body 32 of the present embodiment has an opening 71 for placing the lid member 34, so the rigidity of the bumper body 32 becomes a problem. However, the frame portion 75 of the reinforcement member 33 is provided so as to surround the entire periphery of the opening 71, and the reinforcement member 33 is attached to the skeletal members 11 a and 11 b of the vehicle body 11 having high rigidity via the bracket member 30. Since it is being fixed, it can control that bumper main part 32 changes. Therefore, the lid member 34 provided in the bumper main body 32 can be accurately arranged at a predetermined position with respect to the box main body 31 on the vehicle body 11 side.

  Although the electric vehicle in which the storage box portion is disposed in the rear bumper portion has been described in the above embodiment, the storage box portion may be provided in a place other than the rear bumper portion (for example, the front bumper portion). The storage box structure of the present invention can also be applied to a hybrid vehicle using both an internal combustion engine and a motor. In carrying out the present invention, it goes without saying that the structure and arrangement of the components of the invention including the vehicle body, the bracket member, the box body, the bumper body, the reinforcement member, and the lid member can be changed as appropriate.
