Description
Technical Field
The utility model relates to a car body substructure.
Background
In general, when a tire is replaced with a flat tire, it is necessary to float the tire from the ground. At this time, the vehicle body can be jacked up by arranging the jack at a jacking position set on the vehicle body.
Conventionally, the lift-up portions are often set on lower flanges of side members that are located at both ends in the vehicle width direction and extend in the vehicle length direction. More specifically, a cutout portion is formed as a lift-up portion in a front end portion (rear portion of the front wheel) and a rear end portion (front portion of the rear wheel) of a lower flange of the side member extending in the vehicle length direction, and a head portion of the jack is fitted into the cutout portion, whereby the jack can be positioned below the cutout portion. In addition, in general, a side sill outer cover member that covers the side sill from the outside in the vehicle width direction is also formed with a mark for indicating a raised portion.
In the case where the vehicle is an electric vehicle, a large-capacity battery pack is generally disposed under the floor, and an impact absorbing member is generally disposed below the side sill in order to protect the battery pack in the event of a side collision of the vehicle. When the impact absorbing member is disposed below the side sill, the lower flange of the side sill is covered with the impact absorbing member. Therefore, in a vehicle in which the impact absorbing member is disposed below the side sill, the raised portion is often set on the bottom surface of the impact absorbing member.
However, unlike the structure in which the raised-up portion is set on the lower flange of the side sill, in the case where the raised-up portion is set on the bottom surface of the impact absorbing member, it is not possible to form the notched portion in the impact absorbing member, and therefore, there is a problem in that it is difficult to clearly show the raised-up portion.
In some vehicles, the lower end portion of the side door covers the entire outer side of the side sill. In such a vehicle, since the side sill outer cover member is covered with the door cover member, there is a problem that it is difficult to see a mark for marking the lift-up portion.
In this regard, it is conceivable to provide a mark for indicating a lift-up portion on the side door, or to indicate a lift-up portion on the impact absorbing member, or the like. However, these practices again result in a decreased aesthetic appearance of the vehicle and increased manufacturing costs.
SUMMERY OF THE UTILITY MODEL
In view of the above, an object of the present invention is to provide a vehicle body lower structure that can clearly show a jacking portion and does not reduce the appearance of a vehicle.

The vehicle body lower structure of the present invention has an advantage that an extension portion extending inward in the vehicle width direction is formed on the bottom wall portion of the side sill outer, and the front end of the inner side in the vehicle width direction of the extension portion reaches the vicinity of the lift-up portion, so that the front end of the extension portion defines a boundary of the lift-up portion on the impact absorbing member outside in the vehicle width direction. At the same time, two projecting portions that project further inward in the vehicle width direction are formed at the front end of the extension portion on the vehicle width direction inner side, and these two projecting portions are located respectively on the front side and the rear side in the vehicle length direction of the lift-up portion, that is, the lift-up portion is sandwiched between the two projecting portions, and therefore, the position of the lift-up portion in the vehicle length direction can be clearly shown by these two projecting portions. Thus, the user can easily recognize the position of the jack-up portion at the lower portion of the vehicle.
In the above configuration, the raised portion can be clearly shown only by providing the extension portion or the like extending toward the inside in the vehicle width direction below the impact absorbing member in the side sill garnish member, and therefore, the appearance of the vehicle is not deteriorated, the structure is simple, and the cost is not significantly increased.
In the vehicle body lower structure of the present invention, preferably, a mark for marking the lift-up portion is formed on the extension portion. With this structure, the jacking portion can be more clearly shown.

Detailed Description
Hereinafter, a vehicle body lower structure according to an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to the contents described in the following embodiments. In addition, the dimensional relationship (length, width, etc.) in each drawing does not reflect the actual dimensional relationship.
Fig. 1 is a bottom view schematically showing a vehicle body lower portion structure of the present embodiment. Fig. 2 is a cross-sectional view schematically showing the vehicle body lower portion structure of the present embodiment. In each figure, arrow Fr indicates the front side In the vehicle length direction, arrow In indicates the inside In the vehicle width direction, and arrow Up indicates the upper side In the vertical direction.
In this embodiment, the vehicle body lower structure of the present invention is applied to an electric vehicle equipped with a large-capacity battery pack 20. As shown in fig. 1 and 2, a floor panel 10, a battery pack 20, a lower cover 11, a lower cover 13, a side member 30, an impact absorbing member (hereinafter referred to as an "EA member") 40, and a side member garnish member 1 are provided at a lower portion of a vehicle body.
The floor panel 10 constitutes a floor in the vehicle compartment, and both ends in the vehicle width direction thereof are connected to side members 30 as shown in fig. 2. The lower cover 11 and the lower cover 13 are used to cover projections and depressions made by various members of the vehicle bottom to reduce air resistance, allowing air to smoothly pass under the vehicle. The front lower cover 11 covers, for example, the bottom of a suspension (not shown), and the middle lower cover 13 covers a part of the bottom of the battery pack 20.
The battery pack 20 is used to supply power to a power unit (not shown) such as a motor on the electric vehicle. As shown in fig. 2, the battery pack 20 is disposed between the base plate 10 and the intermediate lower cover 13.
The side members 30 as framework members extend in the vehicle length direction along the lower edges of the side door openings at both ends in the vehicle width direction of the floor panel 10. As shown in fig. 2, the side sill 30 is a member having a closed cross-sectional structure formed by welding together a side sill inner panel 31 having a substantially hat-shaped cross section and a side sill outer panel 33 having a substantially hat-shaped cross section, and a side sill reinforcement 35 serving as a reinforcing member is disposed inside the member.
As shown in fig. 2, the EA member 40 extends in the vehicle length direction along the side member 30 below the side member 30, and is located between the battery pack 20 and the side door 50 in the vehicle width direction. Here, the EA member 40 is, for example, a member made by extrusion molding of an aluminum material. The EA member 40 is partitioned by a plurality of partition walls 41 to form a plurality of closed cross-sectional spaces 43 aligned in the vehicle width direction. As shown in fig. 1, the EA member 40 is fixed to the side sill 30 and the like by bolts 45, 47 and the like.
In the vehicle body lower portion structure of the present embodiment, since the EA member 40 is provided, the EA member 40 is deformed by deformation of the side door 50 and the side sill 30 in the event of a side collision of the vehicle, and thus, impact energy can be absorbed, and the battery pack 20 can be protected.
The side sill outer 1 is a resin member provided to improve the appearance of the vehicle and covering the side sill 30 and the EA member 40. The side sill outer 1 has a side wall portion 3 covering the side sill 30 and the EA member 40 from the outside in the vehicle width direction, and a bottom wall portion 5 extending from the lower end portion of the side wall portion 3 to the inside in the vehicle width direction and covering a part of the bottom portion of the EA member 40 (the end portion on the outside in the vehicle width direction).
In the electric vehicle according to the present embodiment, in order to improve the appearance of the vehicle, a door trim member 51 is provided at the lower end portion of the side door 50, and the lower end portion of the side door 50 extends downward to cover the entire outer side surface of the side sill 30. Therefore, as shown in fig. 2, the side wall portion 3 of the rocker outer 1 is entirely covered by the door trim member 51 when viewed from the outside in the vehicle width direction.
Here, in order to make the structure of the present embodiment easy to understand, a description will be given of a vehicle body lower portion structure of the related art.
Fig. 3 is a diagram schematically showing a vehicle body lower portion structure of a vehicle 100 according to the related art. In fig. 3, a partially enlarged portion a shows a front end portion (rear of the front wheel 170) of the lower flange of the side member 130 as viewed from below, and a partially enlarged portion B in fig. 3 shows a rear end portion (front of the rear wheel 180) of the lower flange of the side member 130 as viewed from below. As shown in fig. 3, notches 137 as raised portions are formed in the front end portion and the rear end portion of the lower flange of the side member 130, and a mark 109 for marking the raised portions is formed in the side member outer 101 covering the side member 130 from the outside in the vehicle width direction. Therefore, in the case of such a vehicle 100, the user can recognize the jack-up portion through the mark 109 and then position the jack by fitting the head portion of the jack into the cutout portion 137 of the side sill 130.
However, in the electric vehicle according to the present embodiment, since the lower flange of the side member 30 is covered with the EA member 40, the rising portion JP is often set on the bottom surface of the EA member 40. However, in the case where the lift-up portion JP is set on the bottom surface of the EA member 40, a cut portion cannot be formed in the EA member 40 in order to secure the strength of the EA member 40, and thus it is difficult for the user to find the lift-up portion JP. On the other hand, since the lower end portion of the side door 50 extends downward until the side sill 30 is completely covered, the side sill garnish 1 is covered with the door garnish 51, and even if a mark for indicating the lifted portion JP is formed on the side wall portion 3 of the side sill garnish 1, the mark is not easily visible.
In order to solve the above problem, for example, a mark for indicating the lift-up portion JP may be formed on the side door 50 or the EA member 40, but this may affect the appearance of the vehicle and increase the cost.
In contrast, in the vehicle body lower portion structure of the present embodiment, the raised portion JP is set on the bottom surface of the EA member 40, and as shown in fig. 1 and 2, the extension portion 7 is formed on the bottom wall portion 5 of the side sill outer 1, and the extension portion 7 extends inward in the vehicle width direction below the EA member 40 until the front end of the vehicle width direction inner side reaches the vicinity of the raised portion JP.
As shown in fig. 1, two projecting portions 7a and 7b are formed at the front end of the extension portion 7 on the inner side in the vehicle width direction, and project further inward in the vehicle width direction. The protruding portion 7a is located on the front side of the lift-up portion JP in the vehicle length direction, and the protruding portion 7b is located on the rear side of the lift-up portion JP in the vehicle length direction. Thus, the lift-up portion JP is sandwiched between the protruding portion 7a and the protruding portion 7b in the vehicle length direction. Further, a triangular mark 9 for indicating the lift-up portion JP is formed on the extension portion 7 by embossing or the like.
In the vehicle body lower portion structure according to the present embodiment, the extension portion 7 extending inward in the vehicle width direction is formed in the bottom wall portion 5 of the rocker outer 1, and the front end of the extension portion 7 on the vehicle width direction inner side reaches the vicinity of the lift-up portion JP. Therefore, the position of the front end of the extension portion 7 corresponds to the boundary of the lift-up portion JP on the outer side in the vehicle width direction, and the user can grasp the position of the lift-up portion JP in the vehicle width direction by the front end of the extension portion 7. Meanwhile, since the two projecting portions 7a, 7b projecting further inward in the vehicle width direction are formed at the front end of the extension portion 7, the lift-up portion JP is sandwiched between the two projecting portions 7a, 7b in the vehicle length direction. Therefore, the user can easily see the lift-up portion JP while avoiding the bolts 45, the bolts 47, the lower cover 11, the lower cover 13, and the battery pack 20, and then place the head 60 of the jack at the lift-up portion JP.
In addition, since the triangular mark 9 for marking the lift-up portion JP is formed on the extension portion 7, the user can easily recognize the position of the lift-up portion JP.
In the vehicle body lower structure of the present invention, the position of the raised portion JP is shown only by adding the extension portion 7 extending toward the inside in the vehicle width direction below the EA member 40 to the bottom wall portion 5 of the side sill garnish 1, so that the appearance of the vehicle is not deteriorated, the structure is simple, and the cost is not greatly increased.
