Description

[0001] The present invention relates to a rear structure of a motor vehicle body, in which a battery is mounted on the back of a backrest, a battery cover is provided which covers at least a back surface of the aforementioned battery, and a parcel shelf extending rearwardly on a vehicle from an upper end portion of said backrest so as to cover an upper portion of said battery, and a flange extending downward from an edge portion of said parcel shelf and coupled to an upper end portion of said battery cover by a coupling member. State of the art

[0002] In vehicles such as electric cars and fuel cell vehicles that require the installation of a large battery (electric battery), as disclosed in Patent Document 1, for example, a battery is mounted behind a backrest of a rear seat in a portion corresponding to a trunk of a general automobile. Since the battery has a high voltage, a top surface of the battery exposed rearward from an upper end of the backrest is covered by a parcel shelf, and a rear surface of the battery exposed when a tailgate is opened is covered by a rear cover serving as a battery cover to prevent vehicle occupants from easily contacting the battery.

[0003] Although the parcel shelf has a separating function and separates a normally used space from the battery or additional high-voltage devices as described above, the parcel shelf is formed with such a plate thickness and from such a material that it obtains a certain rigidity because the parcel shelf is arranged horizontally over an entire vehicle width and is supported exclusively by support members at both ends.

[0004] On the other hand, the back cover, which covers the back surface of the battery, is made of a material that is as thin and light as possible, thus reducing the weight.

[0005] Therefore, the conventional rear cover is soft and is easily warped compared to the parcel shelf.

[0006] Patent Document 1: Japanese Patent Application Laid-Open No. 2005-112284

[0007] From JP 2008-195090 A, a mounting structure of a battery instrument for a vehicle is known, which is capable of improving the usability of a luggage compartment. Although a space under a rear upper panel has not been effectively used as a trunk in a conventional vehicle, this battery instrument for a vehicle is arranged near a bottom of the rear upper panel. A space above a floor surface that can be used as a trunk is increased by the effectively utilized space. In addition, the floor surface is formed flat up to an innermost part (an end part in front of the vehicle) of the luggage compartment. Summary of the invention

[0008] In the above conventional arrangement, the rear cover is soft and easily warped compared to the parcel shelf, so that when, for example, an insertion hole (interlocking member insertion through hole) of a coupling member (a clip or the like) formed in a flange extending downward from an edge portion of the parcel shelf and an insertion hole of the coupling member formed in an upper end portion of the rear cover are offset from each other, the upper end portion of the rear cover is pressed by the coupling member and easily warped. As a result, a problem occurs in that the upper end portion of the rear cover moves in an alignment direction of the flange of the parcel shelf, and the coupling member cannot be smoothly inserted into the insertion hole in the upper end portion of the rear cover.

[0009] The present invention has been made in view of the above circumstances, and an object thereof is to provide a rear structure of a vehicle body which can improve the operability of a coupling operation between a flange extending downward from an edge portion of a parcel shelf and an upper end portion of a battery cover.

[0010] The present invention is presented with reference to a rear structure of a motor vehicle body. The vehicle body rear section comprises: a battery mounted at the rear of a backrest, a battery cover covering at least a back surface of the battery, and a parcel shelf extending rearwardly in a vehicle from an upper end portion of the seat back so as to cover an upper portion of the battery, the rear structure of a motor vehicle body being characterized in that the parcel shelf comprises a flange extending downwards from an edge portion of the parcel shelf, the flange of the parcel shelf can be coupled to an upper end section of the battery cover by a coupling member, wherein a bracket is mounted on a flange surface of the parcel shelf flange, which bracket extends from the edge portion of the parcel shelf at a distance downwards from the flange surface and The flange, the upper end portion of the battery cover, and the bracket are coupled together by the coupling member when the upper end portion of the battery cover is inserted between the flange and the bracket into the gap. (Claim 1).

[0011] In the above-described configuration, the bracket is mounted on the flange of the above-mentioned parcel shelf at a distance from the flange surface of the above-mentioned flange, and the above-mentioned flange, the above-mentioned upper end portion of the above-mentioned battery cover, and the bracket are coupled to each other by the above-mentioned coupling member when the upper end portion of the battery cover is inserted between the above-mentioned flange and the bracket. In this way, even when the coupling member applies pressure to the upper end portion of the battery cover during a coupling operation, the upper end portion of the battery cover can be received by the bracket, and thereby the battery cover can be prevented from being warped in a direction away from the flange of the parcel shelf (escape direction).The feasibility of the coupling operation between the flange extending downward from the edge portion of the parcel shelf and the upper end portion of the battery cover can thus be improved (claim 1).

[0012] The present invention can achieve the following advantage.

[0013] The above-mentioned bracket is formed along a corner portion of the flange of the above-mentioned parcel shelf and is mounted on the above-mentioned flange, one end section of the above-mentioned battery cover in the vehicle transverse direction is bent towards the front of the vehicle and an upper end portion of a corner portion of the above-mentioned battery cover is inserted between the corner portion of the flange of the above-mentioned parcel shelf and the bracket (claim 2).

[0014] The above-mentioned bracket is formed along the corner portion of the flange of the above-mentioned parcel shelf and fixed to the above-mentioned flange, the upper end portion of the corner portion of the above-mentioned battery cover is inserted between the corner portion of the flange of the above-mentioned parcel shelf and the bracket, the parcel shelf can thus be restricted in the front, rear, right and left directions, and since the parcel shelf only needs to be positioned with a portion other than the corner portion of the parcel shelf over the upper end portion of the battery cover in the coupling process, the operability of the coupling process can be further improved (claim 2).

[0015] The present invention can achieve the following advantage.

[0016] In the above-mentioned bracket, a guide portion is provided which guides the upper end portion of the above-mentioned battery cover between the above-mentioned flange and the bracket (claim 3).

[0017] The guide portion that guides the upper end portion of the aforementioned battery cover between the aforementioned flange and the bracket is provided in the aforementioned bracket, and therefore the upper end portion of the aforementioned battery cover can be easily inserted between the aforementioned flange and the bracket. Thus, the operability of the aforementioned coupling process can be further improved (claim 3).

[0018] The present invention can achieve the following advantage.

[0019] At a rear end portion of the above-mentioned parcel shelf, a damping material compressed by a tailgate is provided (claim 4).

[0020] The damping material compressed by the tailgate is provided at the rear end portion of the above-mentioned parcel shelf, and therefore the influence of an air pressure applied to the battery cover when the tailgate is closed can be absorbed by the damping material (claim 4). Advantageous effects of the invention

[0021] The present invention can provide the rear structure of a vehicle body which can improve the operability of the coupling operation between the flange extending downward from the edge portion of the parcel shelf and the upper end portion of the battery cover.

[0022] Hereinafter, an embodiment of the present invention will be described based on the drawings.

[0023] Fig. 1(a) to 1(c) and Fig. 5 show a rear structure of a motor vehicle body of an electric car. The electric car includes a large battery 1 (an electric battery, see Fig. 5) mounted on the back of a backrest on a floor panel, and a tailgate 2 which is pivoted on an upper side about a transverse axis O (see Fig. 5) is pivotable. Reference number 3 in Fig. 1(a) indicates a rear bumper.

[0024] The aforementioned backrest is a part that accommodates and supports the back of a passenger (a seated person) and, together with a seat cushion that accommodates and supports the buttocks and thighs of a passenger, forms a rear seat (a rear seat) of a motor vehicle. The backrest is pivotable at its bottom about a transverse axis and can be folded between a standing position and a position lying on the seat cushion.

[0025] Batteries of electric cars are typically large, and the battery 1 of the electric car in the present embodiment is also large and therefore occupies a large area of ​​a trunk behind the seatback. In this type of electric car, in which the large battery 1 is mounted on the back of the seatback, it is necessary to prevent vehicle occupants from easily coming into contact with the battery 1. Therefore, a front cover 4 (see Fig. 1 (c)) for covering the front surface of the battery 1 which is exposed when the seatback is tilted forward, and a rear cover 5 (corresponding to a battery cover) for covering a rear surface of the battery 1 which is exposed when the tailgate 2 is opened, and a parcel shelf 6 which extends from an upper end portion of the seatback to the vehicle rear side Rr to cover the battery 1 on the upper side.

[0026] In gasoline-powered vehicles, the rear side of the seatback serves as a trunk space, and the aforementioned parcel shelf serves as a horizontal storage area from the top of the seatback to the tailgate. When the parcel shelf is also attached to the vehicle body, the parcel shelf can be secured to a vehicle side section only by fitting a concave fitting portion of the parcel shelf onto a side shaft portion of a side panel as an interior material. Furthermore, the parcel shelf is designed to rotate about the axis of the side shaft portion, so that the parcel shelf does not interfere with the loading and unloading of a storage space because the parcel shelf rotates about the axis of the side shaft portion when loading and unloading items.

[0027] However, in the aforementioned electric vehicle according to the present invention, the parcel shelf 6 has a partitioning function and separates a normally used space from the battery 1 or additional high-voltage devices. Therefore, the parcel shelf 6 has a structure in which, unlike the parcel shelf of the gasoline-powered vehicle, the parcel shelf 6 is rotated about the transverse axis only when the parcel shelf 6 is being fixed or undergoes maintenance. The parcel shelf 6 is provided with the aforementioned partitioning function, and both of its surfaces are horizontally supported in the vehicle transverse direction. Therefore, the parcel shelf 6 is formed with a plate thickness and from a material that imparts a certain rigidity, and is formed, for example, from a hard wood material with a plate thickness of 2.5 mm. Parcel shelf 6 and supporting structure of parcel shelf 6

[0028] As in Fig. 2(a) and Fig. 2(b), the parcel shelf 6 is formed in the shape of a laterally elongated rectangular shell having a flange 16 extending downward from the entire outer edge region, and an intermediate portion in the longitudinal and width directions (vehicle longitudinal direction) is provided as a concave portion 47 (see Fig. 5), which is concave downwards. As in Fig. 5, the parcel shelf 6 extends from near the upper end section of the backrest in the longitudinal direction of the vehicle to near the tailgate trim 7 of the tailgate 2.

[0029] In the aforementioned concave portion 47, a large vent opening 47H (see Fig. 5 and Fig. 6(c)) having a laterally elongated rectangular shape. A laterally elongated air intake duct 8 is also attached to an upper surface of the parcel shelf 6 so as to cover the above-mentioned vent opening 47H and rises from the upper surface of the parcel shelf 6. The air intake duct 8 includes a front wall 8M that extends obliquely upward toward the rear, an upper wall 8J that has an arc shape in cross section and extends from an upper end portion of the front wall 8M toward the vehicle rear Rr, and a pair of right and left side walls 8S. A rear end portion of the upper wall 8J abuts the upper surface of the parcel shelf 6 and thus also functions as a rear wall. A grille-shaped air inlet 8K is formed substantially over the entire surface of the above-mentioned front wall 8M, and air passing through the air inlet 8K through the above-mentioned vent opening 47H cools the battery 1.

[0030] On a rear side 16A1 of a laterally elongated rear flange 16A of the flange 16 of the parcel shelf 6 (corresponding to a rear end portion of the parcel shelf 6), a plurality of damping rubbers 9 (corresponding to a damping material) are provided, which are compressed by the tailgate trim panel 7. The damping rubbers 9 are annular in cross section.

[0031] As in Fig. As shown in Fig. 6(c), a pair of shoulders 11T, which hold and support both right and left end portions of the rear end portion of the parcel shelf 6 when placed in the horizontal position, are formed separately and project from a pair of right and left side panel trims 11. In the pair of right and left side panel trims 11, side shaft portions 11B are provided, which project toward the inner side W1 in the vehicle transverse direction. As shown in Fig. As shown in Fig. 2(d), a bearing portion 14, to which the above-mentioned lateral shaft portion 11B is rotatably inserted relative to a left-side flange 16B of the parcel shelf 6, is provided, and a bracket 17 is fixed to an inner surface 16B1 (a flange surface facing the inner side W1 in the vehicle transverse direction) of the left-side flange 16B. As shown in Fig. 2(d) and Fig. As shown in Fig. 6(c), a bearing portion 14, to which the above-mentioned side shaft portion 11B is relatively rotatably fitted, is provided in a right-side flange 16C of the parcel shelf 6, and a bracket 17 is fixed to an inner surface 16C1 (a flange surface facing the inner side W1 in the vehicle width direction) of the right-side flange 16C. The bearing portion 14 is formed in a downwardly open "C" shape, and a lower portion of the bearing portion 14 is also cut out. A pair of guide surfaces 13, which widen downward to guide the side shaft portion 11B to the bearing portion 14, extend downward from both open ends of the bearing portion 14. Structure of the back cover 5

[0032] The above-mentioned back cover 5, which covers the back surface of the battery 1, is formed of a thin and light material, thereby reducing its weight, and is formed, for example, of a PP (polypropylene) material with a plate thickness of 2 mm.

[0033] Since the above-mentioned battery 1 is large and occupies a large area of ​​the trunk space on the rear side of the seatback, the rear cover 5 is also set to a length substantially equal to the entire width of the vehicle body rear portion, and the dimension in the vertical direction is set to a length equal to the length from a rear trim panel to the parcel shelf 6. Both right and left end portions of the rear cover 5 extend toward the vehicle front side Fr to cover both right and left side surfaces of the battery 1 from the vehicle width direction outer side W2. As described above, the vehicle width direction end portions of the rear cover 5 (the left and right end portions) are bent toward the vehicle front side Fr.

[0034] Both right and left lower end portions of the rear cover 5 are formed in an arc shape, which is slightly curved when viewed from the vehicle rear side Rr. A large mark M is formed substantially at a central portion of the rear cover 5, which informs a passenger who is clearing the rear through the tailgate 2 that the battery 1 has a high voltage. Both outer sides of the mark M of the rear cover 5 are provided as concave-convex portions 12, which have a wave shape in vertical section. Accordingly, the rigidity and strength of the rear cover 5 are improved.

[0035] As in Fig. 3(a), Fig. 3(b) and Fig. 5, an upper end portion of the rear cover 5 is provided as a flange 15 having an L-shaped cross section, a rear side flange 15A of the flange 15 projects from a portion below the rear side flange 15A toward the vehicle front side Fr, and a left side flange 15B and a right side flange 15C project from a portion below the left side flange 15B or the right side flange 15C toward the inside of the vehicle compartment.

[0036] As in Fig. 7 and Fig. 8(a) to Fig. 8(c), a side portion flange 35 protrudes from a side portion of the rear cover 5 to the outer side W2 in the vehicle width direction, and the side portion flange 35 is laterally inserted between a side trim 60 and a side portion bracket 61 coupled to the side trim 60 (see Fig. 8(a)). A lower flange 36 also projects downward from a lower end portion of the rear cover 5, and a lateral center portion of the lower flange 36 is inserted between a rear cowl 18 and a center bracket 62 coupled to the rear cowl 18 (see Fig. 8(b)). In addition, the lower flange 36 (a lower flange portion) is inserted on both sides of the lateral center portion of the above-mentioned lower flange 36 between the rear cowl 18 and a bracket 63 coupled to the rear cowl 18 (see Fig. 8(c)). Coupling structure of the parcel shelf 6 and the rear cover 5

[0037] As in Fig. 2(b) and Fig. 2(d), a left-side bracket 21 formed in a band plate shape is coupled to an inner surface 16D1 (corresponding to a flange surface) of a left-side corner portion 16D formed by the rear-side flange 16A and the left-side flange 16B of the flange 16 of the parcel shelf 6 at a distance (for example, 2 mm) from the inner surface 16D1.

[0038] As in Fig. 2(b), Fig. 2(c) and Fig. As shown in Fig. 2(d), a right-side bracket 22 formed in a band plate shape is coupled to an inner surface 16E1 (corresponding to a flange surface) of a right-side corner portion 16E formed by the rear flange 16A and the right-side flange 16C of the flange 16 of the parcel shelf 6, spaced apart (for example, by 2 mm) from the inner surface 16E1. Since the parcel shelf 6 is bilaterally symmetrical, the structure of a right-side end portion of the parcel shelf 6 will be described below.

[0039] The right-side bracket 22 is angled along the right-side corner portion 16E of the flange 16 of the parcel shelf 6. Furthermore, both longitudinal end portions of the right-side bracket 22, between which a bending point lies, are each fastened to the inner surface 16E1 of the right-side corner portion 16E of the flange 16 of the parcel shelf 6 with rivets 20.

[0040] As in Fig. 3(a) to Fig. As shown in Fig. 3(e), a right-side corner portion 15E formed by the rear flange 15A and the right-side flange 15C of the rear cover 5 is inserted between the right-side corner portion 16E of the flange 16 of the parcel shelf 6 and the right-side bracket 22, and the right-side corner portion 16E of the flange 16 of the parcel shelf 6, the right-side corner portion 15E of the flange 15 of the parcel shelf 5, and the right-side bracket 22 are coupled together by a pair of clips 23 (corresponding to a coupling member). A pair of insertion through holes 23H (see Fig. 2(c) and Fig. 3(a) to Fig. 3(d)) is formed in the right-side corner portion 15E of the flange 15 of the rear cover 5 and the right-side bracket 22.

[0041] As in Fig. 3(d) and Fig. As shown in Fig. 6(c), in the right-side corner portion 16E of the flange 16 of the above-mentioned parcel shelf 6, coupling portions R1 of the above-mentioned pair of clips 23 are arranged between the fastening portions R2 of the pair of rivets 20, a coupling portion R1 of one of the clips 23 is arranged adjacent to a fastening portion R2 of one of the rivets 20, and a coupling portion R1 of the other clip 23 is arranged adjacent to a fastening portion R2 of the other rivet 20. Thus, the right-side bracket 22 becomes difficult to deform even under pressure from the clips 23, so that a load on the right-side bracket 22 can be reduced.

[0042] In the right-hand bracket 22 there is a guide section 22G (see Fig. 2(c) and Fig. 4(e)) is provided, which guides the right-side corner portion 15E of the flange 15 of the above-mentioned rear cover 5 between the right-side corner portion 16E of the flange 16 of the parcel shelf 6 and the right-side bracket 22. The guide portion 22G is provided inclined such that an upper end portion of the right-side bracket 22 is located on a radially outermost side of the parcel shelf 6 at the uppermost side. The upper end portion of the right-side bracket 22 is angled toward the inside of the right-side bracket 22 and thus provided as a flange 22H. Consequently, the strength of the left-side bracket 22 can be increased.

[0043] The schematic representations of the Fig. 6(a) and the Fig. 6(b) show a method of attaching the parcel shelf 6. The parcel shelf 6 can be attached by attaching methods as described in (1) and (2) below. (1) As in Fig. 6(a), the parcel shelf 6 is lowered directly from above the battery 1, (1a) the storage sections 14 (see Fig. 6(c)) of the parcel shelf 6 are placed from above onto the lateral shaft sections 11B of the side wall panels 11 and (1b) a left-side corner portion 15D of the flange 15 of the rear cover 5 is inserted between the left-side corner portion 16D of the flange 16 of the parcel shelf 6 and the left-side bracket 21, and the right-side corner portion 15E of the flange 15 of the rear cover 5 is inserted between the right-side corner portion 16E of the flange 16 of the parcel shelf 6 and the right-side bracket 22.

[0044] In this case, the above steps (1a) and (1b) are performed simultaneously. (2) As in Fig. 6(b), (2a) the bearing sections 14 of the parcel shelf 6 are placed from the vehicle front side Fr (or from the front top) onto the lateral shaft sections 11B of the side wall panels 11 and (2b) the left-side corner portion 16D of the flange 16 of the rear cover 5 is inserted between the left-side corner portion 16D of the flange 16 of the parcel shelf 6 and the left-side bracket 21, and the right-side corner portion 15E of the flange 15 of the rear cover 5 is inserted between the right-side corner portion 16E of the flange 16 of the parcel shelf 6 and the right-side bracket 22 by rotating the parcel shelf 6 toward the vehicle rear side Rr around the axis of the side shaft portions 11B.

[0045] In the present invention The flange 15 of the rear cover 5 can be held by the left-side bracket 21 and the right-side bracket 22 even when the clips 23 apply pressure to the flange 15 of the rear cover 5 during a coupling process, so that the rear cover 5 can be prevented from being distorted in a direction away from the flange 16 of the parcel shelf 6. Thus, the feasibility of the coupling process can be improved.

[0046] Fig.5 is a vertical sectional side view showing an operation of opening and closing the tailgate 2. The rear cover 5 covers an entire surface of an open part of the trunk at the bottom of the parcel shelf 6, and a distance from the tailgate 2 is set small (for example, 8 mm). In addition, the rear cover 5 is fixed to the parcel shelf 6 solely by the clips 23, and in another position, it is supported solely by the brackets (21, 22, 61, 62, and 63) and not fixed. When the lid is closed, there is a small air leakage path because the rear cover 5 has a large area, so that a large air pressure is applied.In the present invention, since the plurality of damping rubbers 9 compressed by the tailgate trim 7 are provided at the rear of the rear flange 16A of the flange 16 of the parcel shelf 6, the effect of the air pressure can be absorbed by the damping rubbers 9 provided on the parcel shelf 6. As described above, the advantage is also obtained by fixing the upper end portion of the rear cover 5 to the rear end portion of the parcel shelf 6 when the tailgate is opened and closed.

[0047] Since the above-mentioned guide portion 22G is provided in the right-side bracket 22, the right-side corner portion 15E of the flange 15 of the rear cover 5 can be easily inserted between the right-side corner portion 16E of the flange 16 of the parcel shelf 6 and the right-side bracket 22. Other embodiments (1) The above-mentioned bracket may be provided in the center of the back surface of the flange 16 of the parcel shelf 6 in addition to the left-side corner portion 16D or the right-side corner portion 16E of the flange 16 of the parcel shelf 6. (2) Although it is not necessary to consider the appearance of the above-mentioned front cover 4 compared to the rear cover 5, since the front cover 4 is hidden on the back of the rear seat and the front cover 4 can be fixed from the top of the parcel shelf 6 with the front cover 4 on the top, the appearance can be further improved by providing a bracket as in the rear cover 5.
