  With the above configuration, it is possible to provide a vehicle body front structure of an electric vehicle that is lightweight and compact while ensuring steering stability and ensuring the strength of the vehicle body.

  Hereinafter, the best mode for realizing the vehicle body front structure of an electric vehicle according to the present invention will be described based on Example 1 shown in the drawings.

FIG. 1 is a perspective view showing a front body structure of an electric vehicle according to a first embodiment.
Here, the steering device 30 will be described in detail with reference to FIG. FIG. 1 shows the vehicle body front structure with the front suspension 20 removed from the lower support member 5 so that the vehicle front structure can be clearly understood. The front suspension 20 is attached to the lower support member 5. The vehicle body front structure will be described with reference to FIG.

  The vehicle body front part structure forms a lower part of a vehicle compartment or the like together with the front pillar 3 and the like, and the left and right side members (sills) 1 constituting a part of the vehicle body front part structure with the front part connected by the lower front cross member 2. And a lower support member 5 that supports the left and right front suspension arms 22, and a bumper support member 13 that supports the bumper in front of the lower support member 5.

  The side members 1 extend in the front-rear direction at the left and right lower parts of the vehicle body. The side member 1 is connected by a lower front cross member 2 extending between the front end portions in the vehicle body width direction, and by a lower rear cross member 7 between the rear end portions. Left and right front pillars 3 extending upward from the left and right side members 1 are attached to the front end of the side member 1. The left and right front pillars 3 are further connected by a first upper front cross member 4 extending in the vehicle body width direction at a position above the lower front cross member 2. The first upper front cross member 4 is formed so that both end portions thereof are curved rearward and are fixed to the lower front cross member 2. It comes to be located on the front side. The lower support member 5 has a rear end fixed to a central portion of the lower front cross member 2 and protrudes forward of the vehicle body at the vehicle body center position.

  That is, the lower support member 5 projects forward from the center of the lower front cross member 2 and includes a front member 5a and a rear member 5b combined in a T shape. The rear member 5b is on the lower front cross member 2 side, extends in the vehicle front-rear direction, and has a rectangular tube shape with the vehicle front-rear end opened. The front member 5a has a quadrangular cylindrical shape with the left and right ends of the vehicle body opened, and is provided at the front end of the rear member 5b. The other end of the upper support member 6 is fixed, and a bracket 21 is attached to the open end. It has been. A front suspension arm 22 is supported on both end surfaces of the lower support member 5 through brackets 21 provided in the front-rear direction so as to be swingable.

  The upper support member 6 is connected to the both ends of the first upper front cross member 4 at one end, and is connected to the front end of the lower support member 5 so that the distance between the other ends becomes narrower toward the lower front of the vehicle body. Has been.

  The auxiliary cross member 9 connects the middle of the left and right upper support members 6 in the vehicle body width direction. The auxiliary connecting member 10 connects the auxiliary cross member 9 and the first upper front cross member 4 in the vertical direction.

  The reinforcing plates 11a and 11b are respectively formed between the upper part of the lower support member 5 on the lower front cross member 2 side and the center part of the lower front cross member 2, and the bottom part of the lower support member 5 on the lower front cross member side and the lower front cross. The central part of the member 2 is connected. The reinforcing plates 11a and 11b are made of the same material and shape at the top and bottom, and only the up and down direction at the time of attachment is reversed. For this reason, manufacturing cost can be held down. The front bumper support portion 12 extends in the vehicle body width direction at the front end portion of the lower support member 5 and has a flat front surface. The left and right bumper support members 13 extend from the front member 5 a of the lower support member 5 so as to expand toward the front bumper support portion 12, and play a role of supporting the front bumper support portion 12 to the lower support member 5. .

  That is, in the vehicle body front part structure, the lower front cross member 2, the first upper front cross member 4 and the left and right front pillars 3 have a closed structure when viewed from the front side of the vehicle body, and these members are lower support members. 5 and the upper support member 6 have a closed structure when viewed from the side. Further, the left and right upper support members 6, the first upper front cross member 4 and the lower support member 5 are also configured to be closed.

  As described above, in the configuration of the vehicle body front portion of the first embodiment, since a plurality of closed structures are provided in the vehicle front portion, it is possible to ensure sufficient strength while being lightweight and compact. Thus, the impact can be absorbed at the time of collision.

  Further, each member (the front member 5a and the rear member 5b) of the lower support member 5 has a wall surface cut out in a range that does not affect the strength, and can be reduced in weight.

  Furthermore, since the front part of the vehicle body is composed of as few parts as possible, the maintainability is good.

FIG. 2 is a view showing the vicinity of the steering device 30.
In the structure near the steering device 30, an upper steering shaft 32 a extends from the steering wheel 31, and the upper steering shaft 32 a is built in the column 39. The column 39 is fixed to the bottom 38b of the column fixing portion 38 by a column fixing plate 39a. At this time, the steering wheel 31 is arranged in an offset state from the center of the vehicle body.

  The column fixing portion 38 is fixed to the second upper front cross member 34 at the side portion 38a. The second upper front cross member 34 is provided so as to connect the left and right side pillars 17 above the first upper front cross member 4. The column fixing portion 38 is also fixed to the first upper front cross member 4 via the shaft support member 35.

  The upper steering shaft 32a passes through the upper steering shaft hole 37a and is connected to the lower steering shaft 32b via the universal joint 33a.

  The lower steering shaft 32b passes through the lower steering shaft hole 37b and is connected to the pinion shaft 41 of the steering gear portion 40 through the universal joint 33b. The lower steering shaft hole 37b is fixed to the upper support member 6 by a shaft hole support portion 37c. The shaft hole support portion 37 is fixed to the auxiliary connecting member 10.

  The rack shaft column 42 of the steering gear portion 40 is fixed to the back portion 36a of the steering support lower bracket 36 via the rack shaft column fixing portion 42a. The steering support lower bracket 36 is fixed by the lower front cross member 2 and the left and right upper support members 6. The rack shaft column 42 is fixed to the rear member 5b of the lower support member 5 via the rack shaft column fixing portion 42b.

  As described above, in the steering device of the present embodiment, the steering gear portion 40 is positioned at the center portion and is connected to the steering wheel 31 by the steering shaft 32. If it is not necessary to change the configuration of the lower support member 5 or the like that requires strength, and the steering shaft 32 can be expanded and contracted by, for example, spline fitting, the steering wheel 31 can be moved left and right without changing the steering system components. Any of them can be arranged (corresponding to claim 1).

  Further, the steering wheel 31 is disposed at a position offset from the center of the vehicle body. Therefore, it is possible to secure a space for placing a passenger or luggage next to the driver (corresponding to claim 2).

  The column 39 is fixed to the bottom 38b of the column fixing portion 38 by a column fixing plate 39a. Here, since the column fixing portion 38 is a concave member made up of the side portion 38a and the bottom portion 38b, the column fixing portion 38 and the second upper front cross member 34 can be fixed to form a strong structure. The column fixing portion 38 and the first upper front cross member 4 are fixed by a shaft support member 35. At this time, the column 39 can be firmly fixed to the bottom portion 38b of the column fixing portion 38 by fixing the column 39 with the column fixing plate 39a. With the above configuration, the steering system parts are reliably supported with a light-weight structure, and the vehicle body strength is improved (corresponding to claim 3).

  The steering gear portion 40 is attached to a steering support lower bracket 36 fixed to the lower support member 5 and the upper support member 6. The steering support lower bracket 36 extends upward with respect to the lower support member 5 and penetrates a back portion 36a to which the steering gear portion 40 is attached and a rack shaft extending from the lower support member 5 in the vehicle width direction, and the upper portion 36a and the upper support. It consists of a side plate connecting the member 6. Thus, the strength of the vehicle body is improved with a lightweight structure (corresponding to claims 4 and 5).

  Further, the lower steering shaft hole 37b and the shaft hole support portion 37c are cut out in a range that does not affect the strength, and a light and strong structure can be obtained.

FIG. 3 is a view showing the vicinity of the front suspension 20.
The front suspension 20 mainly includes a front suspension arm 22, a coil spring 23, a shock absorber 24, a stabilizer 25, a stabilizer support portion 26, a bush 27, a steering knuckle 28, and a front suspension fixing portion 29.

  The front suspension arm 22 is supported on the vehicle body side by the lower support member 5 attached to the lower front cross member 2. The lower support member 5 is located at the center of the vehicle body.

  The first upper front cross member 4 is bent and installed so as to protrude forward from the front pillar 3, and the suspension fixing portion 29 is fixed to the front of the first upper front cross member 4 by welding.

  The coil spring 23 reduces the impact from the road surface. The shock absorber 24 absorbs vibrations in the vehicle vertical direction.

  The stabilizer 25 uses the twist of a torsion bar built in the stabilizer 25 when the left and right wheels move up and down while the vehicle is running, and reduces the inclination of the vehicle by using a spring force generated by the twist. In order to cause the stabilizer 25 to twist, the stabilizer 25 needs to be fixed to the vehicle body. In the first embodiment, the stabilizer 25 is bolted to the front bumper support portion 12. That is, the front bumper support part 12 has both a role of supporting the front bumper (not shown) and a role of supporting the stabilizer 25.

  The stabilizer support part 26 fixes the stabilizer 25. The wheel-in motor 8 is also fixed to the stabilizer support portion 26.

  The bush 27 absorbs and reduces shocks in the front-rear direction that cannot be absorbed by the coil spring 23 and the shock absorber 24.

  The steering knuckle 28 is attached to the front suspension arm 22 via a ball joint (not shown), and enables a rotational movement for vertical movement and steering.

  As described above, in the configuration of the front suspension 20 portion of the first embodiment, the lower support member 5 is located at the center of the vehicle body when the front suspension arm 22 is attached, so that it is compact. A sufficient space for mounting the front suspension arm 22 can be secured. Therefore, unlike the conventional configuration having the left and right side members, there is no concern about the interference between the front suspension arm, the wheels, and the side members, thereby increasing the degree of freedom in design.

  Further, when the lower support member 5 is located at the center of the vehicle body, the suspension arm 22 can be lengthened even when the vehicle width is designed to be small as in a small vehicle. As a result, it is possible to suppress a change in suspension geometry due to the swing of the front suspension arm 22, and to ensure the stability and steering performance of vehicle travel.

  Further, the first upper front cross member 4 is bent and installed so as to protrude forward from the front pillar 3, and a suspension fixing portion 29 is fixed to the front of the first upper front cross member 4 by welding. Yes. It is possible to absorb the impact from the front by bending, and since the suspension fixing portion 29 is fixed to the front of the first upper front cross member 4, the front suspension 20 is optimally positioned to absorb the impact. Can be attached to.

  Further, the stabilizer 25 is bolted to the front bumper support portion 12. That is, the front bumper support part 12 can combine the role of supporting the front bumper (not shown) and the role of supporting the stabilizer 25.

  Since the front suspension arm 22 is supported by the lower support member 5 composed of each of the quadrangular columnar members (the front member 5a and the rear member 5b) whose wall surfaces are cut out within a range not affecting the strength, the strength is ensured with a small amount of material. Can lead to cost reduction. Since the front suspension arm 22 is firmly fixed, it is possible to ensure sufficient strength both in the front-rear direction and in the lateral force, and the burden on the shock absorber 24 can be reduced. Further, since each member has a wall surface cut out, the weight can be reduced.

FIG. 4 is a diagram illustrating a case where the small window 14 is provided at the lower part of the front vehicle body panel 16.
A small window 14 is provided in a lower portion of the front body panel 16 in addition to the windshield 15. Thereby, for example, when it is difficult to see the situation of the lower front part of the vehicle such as in a garage, it is easy to drive by looking at the lower part of the vehicle through the small window 14 and it is possible to prevent collision with an obstacle. Therefore, it is possible to provide a car that is easy to drive especially for elderly people.

The effects obtained by the configuration described in this embodiment are listed below.
1) Since a plurality of closed structures are provided at the front part of the vehicle body, sufficient strength can be ensured and an impact can be absorbed during a collision.

  In addition, since the steering gear portion 40 is positioned at the center portion and is connected to the steering wheel 31 by the steering shaft 32, the configuration of the vehicle body side, particularly the lower support member 5 that requires strength, is changed. There is no need. In addition, for example, if the steering shaft 32 can be expanded and contracted by spline fitting or the like, the steering wheel 31 can be arranged on either the left or right without changing the steering system components.

  Further, a wheel-in motor 8 is used as a front wheel drive motor. As a result, the space can be reduced, and the weight and simplification of the vehicle body structure can be achieved. Therefore, cost reduction can be achieved (corresponding to claim 1).

  2) The steering wheel 31 is disposed at a position offset from the center of the vehicle body. Therefore, it is possible to secure a space for placing a passenger or luggage next to the driver (corresponding to claim 2).

  3) The column 39 is fixed to the bottom 38b of the column fixing portion 38 by a column fixing plate 39a. Since the column fixing portion 38 is a concave member made up of the side portion 38a and the bottom portion 38b, the column fixing portion 38 and the second upper front cross member 34 can be fixed to form a strong structure. Since the column fixing portion 38 and the first upper front cross member 4 are fixed by the shaft support member 35, the column 39 is fixed to the bottom portion 38b of the column fixing portion 38, thereby firmly fixing the column 39. be able to. Accordingly, the steering system parts are reliably supported with a lightweight structure, and the vehicle body strength is improved (corresponding to claim 3).

  4) The steering gear portion is attached to a steering support lower bracket fixed to the lower support member and the upper support member. Accordingly, the vehicle body strength is improved with a lightweight structure (corresponding to claim 4).

  5) The steering support bracket 36 extends upward with respect to the lower support member 5 and penetrates the back portion 36a to which the steering gear portion 40 is attached and the rack shaft extending from the lower support member 5 in the vehicle width direction, and the back portion 36a and the upper support member. 6 is composed of side plates that connect the two. Accordingly, the vehicle body strength is improved with a lightweight structure (corresponding to claim 5).

  6) The middle portions of the left and right upper support members 6 are connected by the auxiliary cross member 9 in the vehicle body width direction. Further, the auxiliary cross member 9 and the first upper front cross member 4 are connected by the auxiliary connecting member 10. That is, the strength between the left and right upper support members 10 and the first upper front cross member 4 can be improved with a lightweight structure. Thereby, the energy absorption capability at the time of a collision can be improved (corresponding to claim 6).

  7) The small support plate 11 is used to connect the lower support member 5 and the central portion of the lower front cross member 2. The reinforcing plate 11 has a width that is narrower on the front side than on the rear side, and the wall surface is cut out in a range that does not affect the strength. That is, since the reinforcing plate 11 is small and the front side is narrower than the rear side, the strength between the lower support member 5 and the lower front cross member 2 is improved while preventing interference with the front suspension arm 22. Can be made. Further, since the wall surface of the reinforcing plate 11 is cut out, the weight can be reduced. As the weight is reduced, the wheel-in motor 8 can be a low-power motor, so the size of the wheel-in motor 8 can be reduced, and the space can be reduced. (Corresponding to claim 7).

  8) A front bumper support portion 12 extending in the vehicle body width direction is provided at the front end portion of the front member 5a of the lower support member 5, and the front bumper support portion 12 has a flat front surface. That is, the front bumper support portion 12 can absorb an impact with a simple structure. Moreover, since the front surface has a flat structure, the bumper can be easily attached. (Corresponding to claim 8).

  9) The front bumper support portion 12 is attached to the lower support member 5 by left and right bumper support members 13 that expand from the front end portion of the lower support member 5 toward the vehicle body. That is, it is possible to support the front bumper support portion 12 with a simple and lightweight configuration, and to increase the collision energy absorption capability at the time of collision (corresponding to claim 9).

  10) The lower support member 5 is composed of a front member 5a which is a quadrangular prism shape and opens in the left-right direction of the vehicle, and a rear member 5b which is also a quadrangular prism shape and opens in the front-rear direction of the vehicle. Since each member (the front member 5a and the rear member 5b) of the lower support member 5 has a quadrangular prism shape, the lower support member 5 can be prevented from being twisted, and a change in suspension geometry can be suppressed. In addition, the front member 5a and the rear member 5b can ensure sufficient strength, and can improve shock absorption at the time of collision. Furthermore, since the front member 5b is opened in the left-right direction of the vehicle and the front portion is flat, the front bumper support portion 12 can be easily attached (corresponding to claim 10).

  11) The vehicle body side support of the front suspension arm 22 is performed by the bracket 21 provided on the lower support member 5 attached to the lower front cross member 2. Since the lower support member 5 is located at the center of the vehicle body, a sufficient space for mounting the front suspension can be secured even though the structure is compact. This increases the degree of freedom in design because there is no concern about the interference between the front suspension arm or the wheel and the side member unlike the conventional configuration having the left and right side members. Therefore, for example, the vehicle height can be lowered, and the stability of vehicle travel can be ensured.

  Further, since the lower support member 5 is located at the center of the vehicle, the suspension arm 22 can be lengthened even when the vehicle width is designed to be small like a small car. As a result, it is possible to suppress a change in suspension geometry due to the swing of the front suspension arm 22, and to ensure the stability and steering performance of vehicle travel.

  Further, since the front suspension arm 22 is supported by the lower support member 5 made up of each of the quadrangular columnar members (the front member 5a and the rear member 5b) whose wall surfaces are cut out within a range not affecting the strength, the strength is reduced with a small amount of material. As a result, it becomes possible to reduce the cost by reducing the size and weight. Since the front suspension arm 22 is firmly fixed, it is possible to ensure sufficient strength both in the front-rear direction and in the lateral force, and the burden on the shock absorber 24 can be reduced. Further, since each member has a wall surface cut out, the weight can be reduced (corresponding to claim 11).

  12) The first upper front cross member 4 was bent and installed so as to protrude forward from the front pillar 3, and the suspension fixing portion 29 was fixed to the front of the first upper front cross member 4 by welding. Since the first upper front cross member 4 is bent, the impact from the front can be absorbed. Further, since the suspension fixing portion 29 is provided in front of the first upper front cross member 4, the front suspension 20 is attached at an optimal position for absorbing the impact. Therefore, stable operation can be provided (corresponding to claim 12).

  13) The stabilizer 25 is bolted to the front bumper support 12. That is, the front bumper support part 12 has both a role of supporting the front bumper (not shown) and a role of supporting the stabilizer 25. That is, both the support of the front bumper (not shown) and the support of the stabilizer 25 can be performed with one member, and the support can be performed with a small number of members. Therefore, it is possible to achieve a compact and lightweight configuration while ensuring strength, and cost reduction can be achieved (corresponding to claim 13).

  14) The stabilizer support portion 26 serves as both the support portion of the stabilizer 25 and the support portion of the wheel-in motor 8.

  That is, both the stabilizer 25 and the wheel-in motor 8 can be supported by one member, and the support can be performed by a small number of members. Therefore, it is possible to achieve a compact and lightweight configuration while ensuring strength, and cost reduction can be achieved (corresponding to claim 14).

  15) A small window 14 is provided in the front body panel 16. That is, since the field of view of the lower front part of the vehicle is ensured when entering the garage or the like, it is possible to provide a vehicle that is particularly easy to drive for the elderly and the like (corresponding to claim 15).
