  However, in such a conventional battery mounting structure, the front end surface portion of the battery carrier is in contact with the rear end surface portion of the front side member member so that the front side member member receives the load of the battery body. It is configured.

  For this reason, if it is attempted to suppress the deformation of the floor panel member by improving the rigidity of the front side member member, the cross-sectional shape of the front side member member needs to be increased or the plate thickness needs to be increased. There has been a problem that increases.

  Accordingly, an object of the present invention is to provide a battery mounting structure capable of suppressing deformation of a floor panel member while reducing the weight of a front side member member.

  In order to achieve the above object, the present invention is a battery mounting structure in which a battery carrier that houses a battery main body is provided on a lower surface side of a floor panel member at a vehicle rear position of a front side member member.

It is characterized by a battery mounting structure having a slide mechanism in which an allowable space is provided in front of the battery carrier.

  According to the present invention, while the front side member member is absorbing energy while being deformed by load input from the front of the vehicle, the battery carrier is directed toward the front of the vehicle by the slide mechanism. It moves relative to the floor panel member.

  For this reason, the kinetic energy associated with the movement of the battery carrier in the vehicle forward direction can reduce the load input that the front side member member must absorb, the cross-sectional shape of the front side member member, It is possible to reduce the weight by suppressing an increase in the plate thickness.

  Moreover, since the dimension which deform | transforms and moves toward the vehicle rear becomes small, a deformation | transformation of the said floor panel member is suppressed.

  Hereinafter, a battery mounting structure according to an embodiment of the present invention will be described with reference to the drawings.

  1 to 16 show a battery mounting structure according to an embodiment of the present invention.

  First, from the overall configuration, in the battery mounting structure of this embodiment, as shown in FIGS. 1 to 6, on the lower surface side of the floor panel member 3 constituting the lower part of the passenger compartment 2 of the vehicle 1, A pair of left and right are provided, and front side member members 4 and 4 extending in the longitudinal direction along the vehicle longitudinal direction are provided.

  Further, the front side member members 4, 4 have front side member portions 4a, 4a extending along the left and right side edges of the engine room 5 constituting the front portion of the vehicle toward the front of the vehicle.

  Between the passenger compartment 2 and the engine room 5, a dash panel member 6 is formed integrally with the front edge 3a of the floor panel member 3 and is erected substantially vertically upward. Is provided.

  The rear end surfaces 4b and 4b of the front side member members 4a and 4a are abutted and fixed to the dash panel member 6 on the front side surface portion 6a.

  As shown in FIGS. 1 and 2, a brake master back device 7 is fixed to the front side surface portion 6a of the dash panel member 6 in the vicinity of the feet of the driver's seat.

  Further, a tension member 8 as a transmission means is provided on the front side surface portion 6a of the dash panel member 6 so as to straddle the front opening of the center tunnel concave portion 3b of the floor panel member 3 so as to substantially close the opening. .

  The tension member 8 has a longitudinal direction along the vehicle width direction, and both end portions 8a and 8a as fixing portions are connected to the front end edge 3a of the floor panel member 3 and the front side surface portion 6a of the dash panel member 6. It is fixed to the inclined surface portion 6b formed in the vicinity of the joint portion by welding.

  Further, the both end portions 8a and 8a are fixed by being shifted to a position lower by a predetermined dimension h1 than the portion where the rear end surfaces 4b and 4b of the front side member portions 4a and 4a are abutted and fixed. At the same time, it is fixed at a position shifted inward by a fixed dimension w1 in the vehicle width direction.

  For this reason, the front side member members 4 and 4 are shifted from the positions where the dash panel member 6 is started to be deformed toward the rear of the vehicle by a load input from the front of the vehicle. The inertial force of the battery carrier 10 is transmitted at the offset position.

  And, the rear side surfaces 4b, 4b of the front side member portions 4a, 4a of the front side member members 4, 4 are located on the lower surface side of the floor panel member 3 at a position behind the vehicle rather than the portion where the rear end surfaces 4b, 4b are abutted and fixed. 3c is provided with a battery carrier 10 for housing the battery main body 9.

  A slide mechanism 11 is provided between the battery carrier 10 and the floor panel lower side member portions 4c, 4c of the front side member members 4, 4.

  The slide mechanism 11 is provided with horizontal slide flange portions 10a and 10a that protrude from both left and right side edges of the battery carrier 10 and slide the upper surface portion to the lower surface side of the floor panel lower side member portions 4c and 4c. Have.

  The horizontal slide flange portions 10a, 10a are formed with a total of four long holes 10b, 10b having a longitudinal direction along the longitudinal direction of the vehicle.

  In each of the long holes 10b, the shaft portions of the bolt members 12 that are slidably inserted can obtain a movement distance longer than the relative movement distance of the floor panel member 3 of the battery carrier 10. Each has a longitudinal dimension L2 that is equal to or greater than a predetermined dimension L1 to be described later.

  Each of the bolt members 12 is screwed to the lower surface side of the floor panel lower side member portions 4c, 4c toward the upper side of the vehicle, and the head portions 12a of the bolt members 12 ... The battery carrier 10 is supported by being engaged with the peripheral edge of the long hole 10b so as not to fall down the vehicle.

  Further, the battery carrier 10 is provided with an abutting convex portion 10d at a substantially central portion in the vehicle width direction of the upper surface portion 10c so as to protrude over the substantially entire length of the battery carrier 10 in the vehicle front-rear direction.

  As shown in FIGS. 3 and 5, the front end surface 10 e of the abutting convex portion 10 d has a pressure receiving portion 8 b provided between the both end portions 8 a and 8 a of the tension member 8 when no load is applied. From, it is comprised so that the predetermined dimension L1 may space apart.

  As shown in FIGS. 2, 4, and 6, the front end surface 10 e comes into contact with the pressure receiving portion 8 b by the relative movement of the battery carrier 10 with respect to the floor panel member 3 toward the front of the vehicle. The panel member 6 is configured to transmit the inertial force of the battery carrier 10 to the panel member 6.

  In this embodiment, a predetermined dimension L1 as the space is set.

  By providing this predetermined dimension L1, while the front side member portions 4a, 4a of the front side member member 4 are absorbing energy while being deformed by a load input from the front of the vehicle, the floor panel member 3 On the other hand, the battery carrier 10 is configured to be allowed to move in the forward direction of the vehicle.

  The movable distance until the battery carrier 10 comes into contact with the pressure receiving portion 8b in the vehicle forward direction is approximately the predetermined dimension L1.

  Therefore, in this embodiment, when the battery carrier 10 is fixed to the front side member members 4 and 4 by the bolt members 12... From 8b, the front end face 10e is configured to be separated from the predetermined dimension L1.

  Next, the effect of the battery mounting structure of this embodiment will be described.

  First, the operational effects of the battery mounting structure of this embodiment will be described with reference to a schematic diagram along the history of load input shown in FIG.

  When the front member portion 4a of the front side member member 4 starts to be deformed by a load input from the front of the vehicle 1, as shown in FIG. 7A, the battery body 9 housed in the battery carrier 10 is The slide mechanism 11 starts moving together with the battery carrier 10 toward the front of the vehicle.

  That is, as shown in FIGS. 1, 3, and 5, when there is no load input from the front of the vehicle, a horizontal slide that protrudes from both left and right side edges of the battery carrier 10 in the slide mechanism 11. Bolt members 12... Are inserted into the long holes 10 b and 10 b formed in the flange portions 10 a and 10 a so as to be engaged and fixed, whereby the battery carrier 10 is connected to the front side member members 4 and 4. It is suspended on the lower surface side of the floor panel lower side member portions 4c, 4c.

  Further, a predetermined dimension L1 is provided between the front end face 10e of the battery carrier 10 and the pressure receiving portion 8b of the tension member 8, and the battery carrier 10 can be moved toward the front of the vehicle. A possible space is formed.

  From this state, when the load input is applied from the front of the vehicle, the fixing of the heads 12a of the bolt members 12 inserted through the long holes 10b, 10b is released, and the respective axes of the bolt members 12 ... The part can be slidably moved in the direction of the rear edge of the vehicle within the long hole 10b.

  For this reason, the abutting convex portion 10d of the battery carrier 10 is slid and moved in the vehicle tunnel front-rear direction inside the center tunnel concave portion 3b formed in a recessed manner on the lower surface side 3c of the floor panel member 3. The horizontal slide flange portions 10a and 10a are relatively moved toward the front of the vehicle along the floor panel lower side member portions 4c and 4c substantially simultaneously in the vehicle width direction left and right so as to fill this space. Further, the distance L1 between the front end face 10e and the pressure receiving portion 8b of the tension member 8 is decreased.

  Thus, while the front side member member 4 is absorbing energy while deforming from the state shown in FIG. 7A to the state shown in FIG. The battery carrier 10 is not restrained with respect to the floor panel member 3 by the slide mechanism 11 toward the front of the vehicle, and is slidable in the vehicle front-rear direction.

  Further, in this embodiment, the long holes 10b have longitudinal dimensions L2 that are equal to or larger than a predetermined dimension L1, and the shafts of the bolt members 12 that are slidably inserted are provided on the shafts. Since the movable distance that is longer than the relative movement distance of the floor panel member 3 of the battery carrier 10 is provided, while the battery carrier 10 is relatively moving toward the front of the vehicle, There is no possibility that the shaft portion of the bolt members 12 will bottom out on the vehicle rear side peripheral portion of the long hole 10b.

  Therefore, the battery carrier 10 smoothly moves relative to the floor panel member 3 so that the battery carrier 10 moves in the vehicle front direction as shown by an area S1 (L1 = about S1) shown in FIG. The load input that must be absorbed by the front side member member 4 can be reduced by the amount of kinetic energy associated with the relative movement of the load.

  Therefore, for example, the cross-sectional shape of the front side member portions 4a and 4a of the front side member members 4 and 4 and the increase in the plate thickness can be suppressed, and the weight can be reduced. In FIG. As shown, the amount of retraction of the dash panel member 6 can be reduced and the total length collapse amount can be reduced as compared with the prior art.

  Thus, the dimension of the dash panel member 6 that is deformed and moved toward the rear of the vehicle is reduced, so that the deformation of the floor panel member 3 is suppressed.

  When the battery carrier 10 moves relative to the front of the vehicle, the battery carrier 10 is placed on the pressure receiving portion 8b provided between the both ends 8a, 8a of the tension member 8, as shown in FIG. The front end face 10e of the ten abutment protrusions 10d abuts and is restrained.

  Then, the inertia force of the battery carrier 10 is transmitted to the dash panel member 6 located on the front side of the floor panel member 3 through the both end portions 8 a and 8 a of the tension member 8.

  For this reason, the load input that the front side member portions 4a, 4a of the front side member members 4, 4 must absorb is further reduced.

  Accordingly, the cross-sectional shape and thickness of the front member portions 4a and 4a can be suppressed to reduce the weight, and the deformation of the dash panel member 6 and the floor panel member 3 can be reliably suppressed. I can do it.

  Moreover, in this embodiment, as shown in FIG. 7 (c) and FIGS. 2, 4, and 6, the inertia force of the battery carrier 10 directs the dash panel member 6 toward the front of the vehicle. Since the deformation is attempted, the deformation characteristics of the dash panel member 6 and the floor panel member 3 can be further made desirable.

  In this embodiment, both end portions 8a of the tension member 8 are formed on the inclined surface portion 6b formed in the vicinity of the joint portion with the front end edge 3a of the floor panel member 3 in the front side surface portion 6a of the dash panel member 6. 8a are fixed so as to straddle the front opening of the center tunnel recess 3b.

  For this reason, desired good deformation characteristics can be given to both the dash panel member 6 and the floor panel member 3, and good deformation characteristics can be given to the left and right balance in the vehicle width direction. .

  Further, while the front side member portions 4a and 4a of the front side member members 4 and 4 are absorbing energy while being deformed by a load input from the front of the vehicle, and further to the rear of the dash panel member 6 toward the vehicle. The battery carrier 10 is slid toward the front of the vehicle by the slide mechanism 11 until the time when the deformation movement is started.

  For this reason, the load input which the said front side member members 4 and 4 must absorb can be reduced by the kinetic energy accompanying the movement to the vehicle front direction of the said battery carrier 10, and the front side member members 4 and 4 can be reduced. It is possible to reduce the weight by suppressing the cross-sectional shape of 4 and the increase in the plate thickness.

  Further, when the state shown in (b) of FIG. 7 is shifted to the state shown in (c) of FIG. 7, the dash is generated by the load input transmitted through the front member portions 4a and 4a. At the time when the deformation movement of the panel member 6 toward the rear of the vehicle is started, the battery carrier 10 is slid toward the front of the vehicle by the slide movement by the slide mechanism 11, and the tension member 8 The inertial force of the battery carrier 10 is transmitted to the dash panel member 6.

  Therefore, the position of the dash panel member 6 in the vehicle front-rear direction can be maintained or further pulled by the tension member 8 toward the front of the vehicle and deformed forward. The deformation of the floor panel member 3 toward the rear of the vehicle is suppressed.

  Therefore, as shown by an arrow b in FIG. 8, the amount of retreat of the dash panel member 6 can be further reduced as compared with the prior art, and an increase in the total amount of collapse is suppressed. it can.

  In this embodiment, as shown in FIG. 1, both end portions 8a and 8a provided on the tension member 8 are abutted against the rear end surfaces 4b and 4b of the front side member portions 4a and 4a and fixed. It is shifted to a position that is lower by a certain dimension h1 than the part that is being fixed, and is fixed at an offset position, and is also fixed at a position that is shifted inward by a certain dimension w1 in the vehicle width direction.

  For this reason, as shown in FIG. 10, the inertial force of the battery body 9 is other than the portion where the rear end surfaces 4b, 4b of the front side member members 4, 4 of the front side member members 4, 4 are abutted and welded. Is transmitted to the dash panel member 6.

  As described above, the fixed positions for transmitting the inertial force of the battery body 9 to the dash panel member 6 by the sliding movement of the battery carrier 10 are the front member portions 4a of the front side member members 4 and 4, 4a is connected, and is shifted from the welded portion where the dash panel member 6 starts to deform toward the rear of the vehicle by a load input from the front of the vehicle 1, so that the front side member directly The load input from the members 4 and 4 is not transmitted to the battery carrier 10.

  In addition, as shown in FIGS. 2 and 6, the vehicle front-rear direction position of the dash panel member 6 is maintained or further moved forward by the inertial force of the battery body 9 transmitted from both ends 8 a, 8 a of the tension member 8. The deformation can be further suppressed, and the deformation of the dash panel member 6 and the floor panel member 3 toward the vehicle rear is further suppressed.

  11 and 12 show Example 1 of the embodiment of the present invention.

  Note that portions that are the same as or equivalent to those in the above-described embodiment are described with the same reference numerals.

  In Example 1, a flat plate-like tension member 18 is provided instead of the tension member 8 as the transmission means of the above-described embodiment.

  The flat plate-like tension member 18 has a substantially rectangular shape with the vehicle vertical direction as the longitudinal direction, and the upper edge portion 18a extends in the vehicle width direction with the cross member member 17 and the dash panel member. 6 and is welded in a state of being sandwiched between the front side surface portion 6a.

  Further, the lower edge portion 18b of the flat plate-like tensile member 18 extends substantially vertically downward so as to substantially close the vehicle front side opening of the center tunnel recess 3b.

  The lower edge portion 18b is formed with an oval locking hole portion 18c at the approximate center in the vehicle width direction with the major axis direction extending along the vehicle width direction.

  The battery carrier 10 that holds the battery body 9 has a locking projection formed on the front end surface 10e of the abutting projection 10d so as to protrude from the front-rear direction of the vehicle in the locking hole 18c. The part 10f is provided integrally.

  Next, the effect of the battery mounting structure of the first embodiment will be described.

  In the battery mounting structure of Example 1, in addition to the operational effects of the battery mounting structure of the above embodiment, the load is further applied from the front of the vehicle in the state shown in FIG. 11 (a) and FIG. 12 (a). When an input is applied, the fixing of the heads 12a of the bolt members 12 inserted through the long holes 10b, 10b is released, and the respective shaft portions of the bolt members 12 are inside the long holes 10b. Thus, the battery carrier 10 is slidable toward the front side of the vehicle.

  During the sliding movement, the load input that the front side member 4 must absorb can be reduced by the kinetic energy associated with the relative movement of the battery carrier 10 in the vehicle front direction.

  Then, as shown in FIG. 11B and FIG. 12B, the engagement hole portion 18c formed in the lower edge portion 18b of the flat plate-like tensile member 18 is engaged with the engagement from the vehicle rear direction. The flat plate-like tension member 18 is moved forward with the battery carrier 10 together with the battery carrier 10 while the locking projection 10f is inserted and the locking projection 10f is locked in the locking hole 18c. It is deformed and moved toward.

  For this reason, it is possible to reliably reduce the dimension of the dash panel member 6 that is deformed and moved toward the rear of the vehicle, and to suppress deformation of the floor panel member 3.

  In addition, since the inertial force of the battery body 9 that deforms the dash panel member 6 can be reliably transmitted to the flat plate tension member 18, the front end surface 10e and the flat plate tension constituting the pressure receiving surface. The degree of freedom in setting the separation distance of the predetermined dimension L3 from the lower edge portion 18b of the member 18 can be increased, and the slide movement distance of the battery carrier 10 that can obtain desired deformation characteristics can be set.

  Other configurations and operational effects are the same as or equivalent to those of the above-described embodiment, and thus description thereof is omitted.

  13 and 14 show Example 2 of the embodiment of the present invention.

  Note that portions that are the same as or equivalent to those in the above-described embodiment are described with the same reference numerals.

  In the second embodiment, a V-shaped tensile member 28 is provided instead of the flat plate-like tensile member 18 as the transmission means of the first embodiment.

  As shown in FIG. 13, the V-shaped tension member 28 is mainly configured by a flat plate member having a substantially V-shape when viewed from the front of the vehicle, and extends obliquely upward and leftward in the vehicle width direction. Upper end portions 28a, 28a provided are respectively fixed to the front side surface portion 6a of the dash panel member 6 by welding.

  Among these, any one upper end part 28a is extended to the upper position vicinity of the front side part 6a in which the said brake master back apparatus 7 is provided, and is fixed by welding.

  The lower edge portion 28b of the V-shaped tension member 28 extends substantially vertically downward so as to substantially block the vehicle front side opening of the center tunnel recess 3b.

  An oval locking hole 28c is formed in the lower edge portion 28b at the approximate center in the vehicle width direction so that the major axis direction is along the vehicle width direction.

  Further, the battery carrier 10 that holds the battery body 9 has a locking projection formed on the front end surface 10e of the abutting projection 10d so as to protrude from the front-rear direction of the vehicle in the locking hole 28c. The part 10f is provided integrally.

  Next, the effect of the battery mounting structure of the second embodiment will be described.

  In the battery mounting structure of Example 2, in addition to the operational effects of the battery mounting structure of the above embodiment, the load is further applied from the front of the vehicle in the state shown in FIG. 13 (a) and FIG. 14 (a). When an input is applied, the fixing of the heads 12a of the bolt members 12 inserted through the long holes 10b, 10b is released, and the respective shaft portions of the bolt members 12 are inside the long holes 10b. Thus, the battery carrier 10 is slidable toward the front side of the vehicle.

  The load input that the front side member 4 must absorb can be reduced by the amount of kinetic energy associated with the relative movement of the battery carrier 10 in the vehicle forward direction.

  Then, as shown in FIG. 13 (b) and FIG. 14 (b), the locking hole portion 28c formed in the lower edge portion 28b of the V-shaped tension member 28 is opened from the vehicle rear direction. The locking projection 10f is inserted and the V-shaped tension member 28 is deformed and moved together with the battery carrier 10 toward the front of the vehicle while the locking projection 10f is locked. Let

  For this reason, the position of the dash panel member 6 in the vehicle front-rear direction can be maintained or further pulled forward by the V-shaped tension member 28 and deformed forward. 6 and the deformation | transformation toward the vehicle rear of the said floor panel member 3 are suppressed.

  In the second embodiment, one upper end portion 28a of the V-shaped tension member 28 is extended to the vicinity of the upper position of the front side surface portion 6a where the brake master back device 7 is provided and fixed by welding. ing.

  For this reason, the front side surface portion 6a of the dash panel member 6 can be deformed in the vehicle forward direction around the vicinity of the upper position of the front side surface portion 6a where the brake master back device 7 is provided.
