[0007] The technical problem that the invention aims to solve

[0008] In the front structure of the vehicle in Patent Document 1, since the power receiving device is fixed to the side frame extending in the front-rear direction of the vehicle body in the suspension frame, the absorption of the impact load caused by the deformation of the side frame is hindered when a collision load is input from the front, and the impact load is difficult to be fully absorbed.

[0009] Components that prevent deformation of the side frames are not limited to power receiving devices; the same technical problems also arise for vehicle-mounted equipment such as auxiliary machines located between the left and right side frames. Summary of the Invention

[0010] The present invention provides a front structure of a vehicle that, by deforming upon the input of an impact load, makes it difficult to prevent the deformation of the side frames even when the on-board equipment is located between the left and right side frames that absorb the impact load.

[0019] According to the present invention, when an impact load is input from the front of the vehicle, the vehicle-mounted equipment detaches from the side frame at the second fixing part, so that even when the vehicle-mounted equipment is located between a pair of left and right side frames, the deformation of the side frame is suppressed by the vehicle-mounted equipment.

[0020] The effects of the invention

[0021] According to the present invention, a front structure of a vehicle is provided that makes it difficult to prevent deformation of the side frames even when the vehicle-mounted equipment is located between a pair of left and right side frames that absorb impact loads by deforming when an impact load is input.

[0043] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, the following description is merely illustrative and is not intended to limit the invention, its applicability, or its uses.

[0044] Figure 1 and Figure 2 This illustrates the front structure of a vehicle according to one embodiment of the present invention. In this embodiment, the vehicle equipped with the front structure 1 according to the present invention is an electric vehicle.

[0045] like Figure 1 and Figure 2 As shown, the front structure 1 of the electric vehicle includes: a front bulkhead 10 that separates the passenger compartment C and the engine compartment E which is equipped with a drive source such as a motor; a pair of left and right front side frames 20 extending forward from the front bulkhead 10; and a subframe (also called a "suspension beam") 30 disposed below the front side frames 20.

[0046] At the front end of each front side frame 20, a main energy-absorbing box 61, composed of a cylindrical body or the like, extends forward to absorb impact loads from the vehicle body. The pair of main energy-absorbing boxes 61 on the left and right sides are connected to each other via bumper reinforcements 62 extending along the width of the vehicle body.

[0047] like Figure 3 and Figure 4As shown, the subframe 30 also has a pair of left and right suspension link support portions (hereinafter also referred to as "link support portions") 31, a main crossbeam 32 connecting the link support portions 31 along the vehicle width direction, a pair of left and right extended side frames (hereinafter also referred to as "side frames") 33 extending forward from the front end of each link support portion 31, and a front crossbeam (hereinafter also referred to as "front beam") 34 and a rear crossbeam (hereinafter also referred to as "rear beam") 35 connecting the side frames 33 at the front end and rear end along the vehicle width direction.

[0048] At the front end of the side frame 33, a secondary energy-absorbing box 63, composed of a cylindrical body or the like, is mounted via a mounting plate or the like. The front ends of the pair of secondary energy-absorbing boxes 63 on the left and right sides are connected to each other via a beam member 64 extending along the width direction of the vehicle body.

[0049] The left and right connecting rod support portions 31 are cylindrical and extend in the longitudinal direction. The left and right connecting rod support portions 31 extend approximately parallel to each other. A front suspension arm 37 is mounted on the outer side of each connecting rod support portion 31 in the vehicle width direction via a bracket 36. A vehicle body fixing portion 41 for fixing the subframe 30 to the floor frame is provided at the rear end of each connecting rod support portion 31, and a rear column-shaped member 42 for connecting the front side frame 20 and the subframe 30 is provided at the middle part of the connecting rod support portion 31 in the longitudinal direction (the front end of the main crossbeam 32).

[0050] The main crossbeam 32 extends along the width of the vehicle body and is erected from the rear end of each link support 31 to the middle, connecting the left and right pairs of link supports 31 to each other. The main crossbeam 32 is flat and its thickness in the vertical direction is smaller than that in the longitudinal direction and the width direction of the vehicle body. The main crossbeam 32 is joined to the inner surface and the upper surface of the link support 31 in the width direction of the vehicle body at both ends by welding or the like.

[0051] Each side frame 33 is a cylindrical shape extending in the front-to-back direction. The front part of the side frame 33 is located on the outer side in the vehicle width direction compared to the rear part. The separation distance between the left and right pairs of side frames 33 increases towards the front. The rear end of the side frame 33 is joined to the front end of the connecting rod support 31 by welding or the like.

[0052] The front beam 34 is a cylindrical component extending along the width direction of the vehicle body. The cross-sectional shape of the front beam 34, orthogonal to the width direction of the vehicle body, is a closed rectangular section. The front beam 34 is mounted between a pair of side frames 33 at the front end of each side frame 33. The portion of the front beam 34 on the outer side in the width direction of the vehicle body is fixed to the side frame 33 by bolts or other fasteners.

[0053] A pair of left and right front side pillar members 43 are provided at both ends of the front beam 34 in the vehicle width direction, which stand upright in a columnar shape from the upper surface 34d of the front beam 34. The upper end of the front side pillar member 43 is connected to the lower surface of the front end of the front side frame 20 by fastening members or the like.

[0054] The rear beam 35 is a cylindrical component extending along the width direction of the vehicle body. The cross-sectional shape of the rear beam 35, orthogonal to the width direction of the vehicle body, is a closed rectangular section. The rear beam 35 is mounted between a pair of left and right side frames 33 at the rear end of each side frame 33. The rear beam 35 is joined to the inner side of the side frame 33 in the width direction of the vehicle body at both ends by welding or the like.

[0055] like Figure 1 As shown, the vehicle has a battery B for driving an electric drive mechanism (not shown) and a contactless charger 70 that receives power from an external source and supplies the received power to the battery B. In this embodiment, the battery B is located on the passenger compartment C side, and the contactless charger 70 is located in the engine compartment E. The battery B and the contactless charger 70 are electrically connected in a manner capable of transmitting and receiving power.

[0056] Reference Figures 1-6 The contactless charger 70 and its mounting structure X are described below. Figure 1 and Figure 2 As shown, the contactless charger 70 is configured across the front beam 34 and the rear beam 35.

[0057] like Figure 4 As shown, the contactless charger 70 includes, for example: a receiving coil 71 that receives magnetic flux generated by current flowing through a power transmission coil buried in the road surface of a parking lot or the like, and generates current through electromagnetic induction to store power in the battery B; a rectifier 72 that rectifies the current of the receiving coil 71; and a housing 73 that houses the receiving coil 71 and the rectifier 72.

[0058] like Figure 5 and Figure 6 As shown, the housing 73 has: a main body portion 74 that houses the receiving coil 71; a protrusion 75 that houses the rectifier 72 and protrudes upward from the main body portion 74; fixing portions 76 and 77 that protrude in a flange-like manner from the periphery of the main body portion 74 in the vehicle width direction for fixing the non-contact charger 70 to the sub-frame 30; and an inclined portion 78 that connects the upper surface of the main body portion 74 and the rear surface of the protrusion 75 in a rib-like manner.

[0059] like Figure 5As shown, the main body 74 is formed in a generally rectangular shape and is flat in the vertical direction. The main body 74 has: a bottom part 74a that is formed in a generally rectangular shape and extends in a generally horizontal direction; a front surface part 74b that extends upward from the front edge of the bottom part 74a; a rear surface part 74c that extends upward from the rear edge of the bottom part 74a; a side part 74d that extends upward from the side edges of the left and right sides of the bottom part 74a; a front upper surface part 74e that extends rearward from the upper edge of the front surface part 74b; and a rear upper surface part 74f that extends forward from the upper edge of the rear surface part 74c. The front upper surface part 74e is narrower in the front-rear direction than the rear upper surface part 74f. A protrusion 75 is disposed between the front upper surface part 74e and the rear upper surface part 74f.

[0060] like Figure 5 and Figure 6 As shown, the protrusion 75 is a generally rectangular parallelepiped that is longer in the width direction than in the longitudinal direction. The protrusion 75 is disposed at a position offset forward from the center of the main body 74 in the longitudinal direction. The protrusion 75 has: a front surface portion 75a extending upward from the rear edge of the front upper surface portion 74e, an upper surface portion 75b extending rearward from the upper edge of the front surface portion 75a, a rear surface portion 75c extending downward from the rear edge of the upper surface portion 75b, and a side surface portion 75d extending downward from both side edges of the upper surface portion 75b and connecting the front surface portion 75a and the rear surface portion 75c.

[0061] The fixing parts 76 and 77 protrude outward from the side portion 74d of the main body portion 74 in the direction of vehicle width. The fixing parts 76 and 77 have a front fixing part (first fixing part) 76 provided on the front right and left sides of the main body portion 74, and a rear fixing part (second fixing part) 77 provided on the rear right and rear left sides of the main body portion 74.

[0062] The inclined portion 78 is formed by a plurality of plate members that form a triangle when viewed from the side. The inclined portion 78 is disposed between the rear surface portion 75c of the protrusion 75 and the rear upper surface portion 74f of the main body 74. The inclined portion 78 is formed to slope upwards towards the front. The plurality of plate members are arranged at equal intervals along the width direction of the main body 74 from the center portion of the body width direction. In this embodiment, the inclined portion 78 is constituted by heat sinks for cooling the non-contact charger 70.

[0063] The inclined portion 78 has a longitudinal edge portion 78a extending vertically along the rear surface portion 75c, a bottom edge portion 78b extending rearward from the lower end of the longitudinal edge portion 78a along the rear upper surface portion 74f, and an inclined edge portion 78c connecting the upper end of the longitudinal edge portion 78a and the rear end of the bottom edge portion 78b.

[0064] The longitudinal edge 78a and the rear surface 75c of the protrusion 75 are approximately at the same height. The bottom edge 78b extends from the rear surface 75c to the center of the rear upper surface 74f in the front-rear direction. The inclined edge 78c rises forward from the center of the rear upper surface 74f in the front-rear direction and ends at the rear upper edge 75e of the protrusion 75. In this embodiment, the angle α formed by the inclined edge 78c and the bottom edge 78b is set to be 20 degrees or more and 45 degrees or less.

[0065] like Figure 4 and Figure 6 As shown, the main body 74 is located between the side frames 33 in the width direction of the vehicle body, and is configured to span the front beam 34 and the rear beam 35, which is a rear component, in the front-rear direction.

[0066] The upper front surface 74e of the main body 74 overlaps with the front beam 34 in the longitudinal direction and is located below the front beam 34. The longitudinal position of the upper front surface 74b of the main body 74 is approximately the same as the front surface 34a of the front beam 34. The longitudinal dimension of the upper front surface 74e is approximately the same as that of the front beam 34. In this embodiment, the main body 74 is fixed to the front beam 34 at the front fixing part 76 with the upper front surface 74e abutting against the lower surface 34b of the front beam 34.

[0067] At least a portion of the rear upper surface portion 74f of the main body 74 overlaps with the rear beam 35 in the longitudinal direction and is located below the rear beam 35. The longitudinal position of the rear surface portion 74c of the main body 74 is approximately the same as the rear surface 35c of the rear beam 35. The longitudinal dimension of the rear upper surface portion 74f is larger than that of the rear beam 35, and an inclined portion 78 is disposed near the front surface 35a of the rear beam 35. In this embodiment, the main body 74 is fixed to the side frame 33 at the rear fixing portion 77 with the rear upper surface portion 74f abutting against the lower surface 35b of the rear beam 35.

[0068] like Figure 6 As shown, the protrusion 75 is disposed between the front beam 34 and the rear beam 35 in the front-rear direction. The protrusion 75 overlaps with the front beam 34 and the rear beam 35 in the vertical direction. The vertical position of the upper surface portion 75b of the protrusion 75 is approximately consistent with the vertical position of the upper surfaces 34d and 35d of the front beam 34 and the rear beam 35.

[0069] The front surface portion 75a of the protrusion 75 is configured to face the rear surface 34c of the front beam 34 from the rear. The front surface portion 75a of the protrusion 75 is the opposing surface to the front beam 34. The rear surface portion 75c of the protrusion 75 is positioned in front of the rear beam 35.

[0070] The inclined section 78 is positioned forward relative to the rear beam 35. More specifically, the rear end 78d of the inclined section 78 extends to the vicinity of the rear beam 35. In other words, the rear beam 35 is positioned near the rear end 78d of the inclined section 78.

[0071] In this embodiment, the area near the rear end 78d of the inclined portion 78 refers to the position where the rear beam 35 abuts against the inclined portion 78 when a specified impact load is input from the front of the vehicle body (e.g., the load input to the vehicle body in a full overlap frontal collision test or offset frontal collision test, etc., in JNCAP, etc.). The rear beam 35 may also be separated vertically from the inclined portion 78 and its front-rear position may overlap with the rear end 78d of the inclined portion 78, or the rear beam 35 may be separated from the inclined portion 78.

[0072] like Figure 4 As shown, the front fixing part 76 protrudes outward from the side portion 74d on the front side of the main body 74 in the vehicle width direction. The front fixing part 76 is located below the front beam 34 and is fixed to the front beam 34 by a front fastening member 76a such as a bolt. The front fixing part 76 and the front beam 34 are fastened in a vertically overlapping state by inserting the front fastening member 76a from below, for example, by screwing it into a welding pad nut or the like provided on the front beam 34.

[0073] The rear fixing part 77 protrudes outward from the side part 74d on the rear side of the main body 74 in the vehicle width direction. The rear fixing part 77 is located below the rear end side of the side frame 33 and is fixed to the side frame 33 by a rear fastening member 77a such as a bolt. The rear fixing part 77 and the side frame 33 are aligned in the vertical direction so that the rear fastening member 77a is inserted from below, for example, by screwing into a welding pad nut or the like provided on the rear beam 35, thereby fixing the non-contact charger 70 to the subframe 30.

[0074] The rear fixing part 77 has a fixing structure X that can detach due to impact loads from the front of the vehicle. The fixing structure X breaks when an impact load is input from the front of the vehicle. In this embodiment, the size (strength) of the rear fastening member (bolt) 77a is set such that when an impact load is input from the front of the vehicle, the rear fastening member 77a breaks, for example, due to tension and / or shear, and the rear fixing part 77 can detach from the side frame 33. The strength of the rear fastening member 77a is less than that of the front fastening member 76a. The rear fastening member 77a may also be made of a bolt whose base can break by an impact load input from the front of the vehicle.

[0075] In the front structure 1 of the vehicle constructed in this way, when an impact load is input from the front of the vehicle, such as Figure 7As shown in (a), the beam member 64 and the auxiliary energy-absorbing box 63 are flattened and deformed while retracting, and the side frame 33 is flattened and deformed and begins to retract. When the side frame 33 retracts, the front beam 34 fixed to the front end of the side frame 33 retracts. The rear surface 34c of the retracted front beam 34 abuts against the front surface 75a of the protrusion 75, and a portion of the impact load is transferred to the non-contact charger 70, while the load in the shear direction acts on the rear fastening member 77a of the rear fixing part 77. As a result, the rear fastening member 77a, which serves as the fixing structure X between the rear fixing part 77 and the side frame 33, breaks, and the connection between the rear fastening member 77a and the side frame 33 is released.

[0076] like Figure 7 As shown in (b), when the contactless charger 70 retracts, the inclined side 78c of the inclined portion 78 abuts against the rear beam 35, and the contactless charger 70 moves downward and rearward along the inclined side 78c towards the rear beam 35. At this time, since the movement of the rear beam 35 is performed in a way that presses downward relative to the contactless charger 70, the rear fastening member 77a, which is fastened in the vertical direction, is pulled out from the side frame 33 downward, and the contactless charger 70 disengages from the sub-frame 30.

[0077] like Figure 7 As shown in (c), as the flattening deformation of the side frame 33 progresses further, the non-contact charger 70 moves rearward so that the rear beam 35 is guided by the inclined portion 78 and positioned on the upper surface portion 75b of the protrusion 75. Thus, since the protrusion 75 moves downward relative to the rear beam 35, it is possible to suppress the flattening deformation of the side frame 33 that would be hindered if the protrusion 75 were sandwiched between the front beam 34 and the rear beam 35.

[0078] The front structure 1 of the vehicle according to the above embodiment has the following effects.

[0079] The front structure 1 of the vehicle includes: a pair of left and right side frames 33, which extend in the front-rear direction;

[0080] Front beam 34, which is mounted between a pair of side frames 33 on the left and right sides; and

[0081] The contactless charger 70, which serves as an on-board device, is located between a pair of left and right side frames 33.

[0082] The contactless charger 70 has:

[0083] Front fixing part 76, which is fixed to the front beam 34; and

[0084] The rear fixing part 77 is located behind the front fixing part 76 and is fixed to the side frame 33 with a fixing structure that can be detached by impact load from the front of the vehicle.

[0085] According to the present invention, when an impact load is input from the front of the vehicle, since the non-contact charger 70 detaches from the side frame 33 at the rear fixing part 77, the deformation of the side frame 33 can be suppressed by the non-contact charger 70 even when the non-contact charger 70 is located between a pair of left and right side frames 33.

[0086] It also features a rear beam 35 (suspension crossbeam 30) as a rear component, which is positioned at the rear compared to the front beam 34.

[0087] The contactless charger 70 has a guide 78 that moves the contactless charger 70 downward when it comes into contact with the front beam 34 due to an impact load from the front of the vehicle.

[0088] According to this structure, when an impact load is applied from the front of the vehicle, the non-contact charger 70 can be reliably moved further downwards and detached.

[0089] The guide section is located on the contactless charger 70.

[0090] The guide section is an inclined section 78 that is opposite to the front surface 35a of the rear beam 35 and slopes upwards towards the front.

[0091] According to this structure, when an impact load is input from the front of the vehicle, the non-contact charger 70 can be easily moved under the rear beam 35 by the inclined part 78, which can facilitate the non-contact charger 70 to detach from the side frame 33.

[0092] The rear beam 35 is positioned near the rear end of the inclined section 78.

[0093] According to this structure, when the non-contact charger 70 moves backward, the rear beam 35 can be reliably brought into contact via the inclined portion 78.

[0094] The rear fastening member 77a (fixing structure X) of the rear fixing part 77 breaks when an impact load is input from the front of the vehicle.

[0095] According to this structure, due to the input of impact load from the front of the vehicle, the rear fastening component 77a breaks, which can easily cause the non-contact charger 70 to detach from the side frame 33.

[0096] The contactless charger 70 has a protrusion 75 that has a surface opposite to the rear surface 34c of the front beam 34.

[0097] According to this structure, due to the input of impact load from the front of the vehicle, the crossbeam presses the front bottom surface and protrusion of the contactless charger backward, thus making it easy for the contactless charger to detach from the side frame.

[0098] The contactless charger 70 has a rear upper surface portion 74f extending behind the protrusion 75.

[0099] The inclined portion 78 is erected from the rear upper surface portion 74f toward the rear upper edge portion 75e of the protrusion portion 75.

[0100] According to this structure, when an impact load is input from the front of the vehicle, the rear beam 35 is prone to move towards the upper surface 75b of the protrusion 75 of the non-contact charger 70. As if the inclined portion 78 is located below the rear upper edge 75e of the protrusion 75, the step generated between the rear surface 75c of the protrusion 75 and the inclined portion 78 can be suppressed, and the movement of the rear beam 35 can be suppressed.

[0101] The rear beam 35 is part of the suspension crossbeam (subframe) 30 used to support the suspension.

[0102] According to this structure, the non-contact charger 70 can be detached from the side frame 33 without using the suspension crossbeam (subframe) 30 to install other components.

[0103] The guide section 78 is a heat sink for cooling the contactless charger 70.

[0104] According to this structure, a guide section 78 can be formed using a heat sink.

[0105] Furthermore, the present invention is not limited to the structure described in the above embodiments, and various modifications can be made.

[0106] In this embodiment, the structure in which the rear fastening member 77a of the rear fixing part 77 breaks when an impact load is input from the front of the vehicle is described, but it is not limited to this, for example, Figure 5 As shown by the double-dotted line, it may also have a slit 77c extending forward from the hole 77b through which the rear fastening member 77a of the rear fixing part 77 is inserted. Thus, when the non-contact charger 70 retracts due to an impact load from the front of the vehicle, the rear fastening member 77a disengages from the rear fixing part 77 through the slit 77c, thereby releasing the fastening between the rear fixing part 77 and the side bracket 33.

[0107] In this embodiment, the structure of the contactless charger 70 (housing 73) with the guide portion 78 has been described, but it is not limited thereto. Figure 6 As shown by the double-dotted line, the guide 78 can also be formed by tilting the rear beam 35 in a forward and upward direction, or the tilting part can be installed in front of the rear beam 35.

[0108] In this embodiment, the structure in which the upper end of the inclined side 78c is located at the upper rear edge of the protrusion 75 has been described, but it is not limited thereto. The upper end of the inclined side 78c can be located at a position where the rear beam 35 abuts against the rear surface portion 75c of the protrusion 75 and the upper end of the inclined side 78c may form a step that does not obstruct the downward and rearward movement of the non-contact charger 70 when an impact load is input. For example, it can be located below the upper rear edge.
