Description

  The present invention relates to a vehicle front body structure for absorbing an impact at the time of a collision.

The front body structure in various vehicles such as passenger cars has a structure for absorbing an impact when it collides with another vehicle or the like. In the front body structure, a pair of left and right side members extending in the front-rear direction of the vehicle are disposed, and the impact at the time of collision is absorbed by the side members. Furthermore, a bumper for absorbing an impact is disposed at the foremost part of the vehicle, and a bumper beam for supporting the bumper is provided (see Patent Document 1). The bumper beam is supported by the side member and transmits an impact at the time of collision to the side member.

  However, there are various types of vehicles ranging from large trucks to light cars and sports cars, and the height position of the bumper beam also changes. Therefore, when vehicles collide, the height position of a side member may shift | deviate between the vehicles. In that case, in the front body structure, the bumper beam of the colliding vehicle is received by the radiator support side extending along the vertical direction of the vehicle. However, the conventional front vehicle body structure may not have the strength to receive the impact received at the time of a collision at the collision between the bearing strength of the radiator support side itself and the attachment location of the radiator support side and the side member. In that case, the impact at the time of a collision cannot be transmitted to the side member by the radiator support side.

  Further, in the case of an offset collision in which parts of the front of the vehicle collide with each other, if a collision occurs outside the radiator support side, the impact at the time of the collision cannot be transmitted to the side member at all. Therefore, in the conventional front body structure, in order to cope with the offset collision, a member extending in the vertical direction is disposed in the vicinity of the left and right ends of the vehicle. There is also a structure that can catch the bumper beam of the vehicle. However, this front body structure increases the number of parts, complicates the structure, and increases design constraints.

  Therefore, an object of the present invention is to provide a front vehicle body structure of a vehicle that does not complicate the structure and can absorb a shock at the time of collision regardless of the type of vehicle and the form of collision.

The vehicle front body structure according to the present invention is attached to a pair of left and right side members provided along the longitudinal direction of the vehicle and a front portion of the pair of left and right side members, and is provided along the vertical direction of the vehicle. A pair of left and right radiator support sides, a pair of left and right first load transmitting members provided between an upper portion of the pair of left and right radiator support sides and an apron upper member; a lower portion of the pair of left and right radiator support sides; and a suspension member A pair of left and right second load transmission members provided between each of them is provided, and the rear surface of the radiator support side is supported by the end portions of the first load transmission member and the second load transmission member .

  In this vehicle front body structure, a pair of left and right radiator support sides are attached to a pair of left and right side members, respectively, so that an impact at the time of collision is transmitted to the side members. Further, in this front vehicle body structure, the upper part of the radiator support side is supported by the apron upper member by the first load transmission member, and the lower part of the radiator support side is supported by the suspension member by the second load transmission member. It is structured to support the support side firmly at the top and bottom. Therefore, in this front body structure, the bumper beam of the opponent vehicle can be firmly received by the radiator support side at the time of a collision, and the load generated on the radiator support side by the impact at the time of the collision can be transmitted to the side member. And in this front part vehicle structure, the impact (energy) at the time of the collision is absorbed by the side member. Also, in the front body structure, the radiator support side is provided over a wide range including the range in which the bumper beam attached at various heights of various vehicles is positioned in the vertical direction, so it can be used from sports cars and light vehicles. Regardless of the type of vehicle, even large trucks can receive the bumper beam of the opponent's vehicle at the radiator support side in the event of a collision. Further, in the front body structure, even when an underride-type collision in which a small car enters the rear part of a large truck, it is possible to receive the bump prevention bumper of the large truck. As described above, the front vehicle body structure is configured based on the conventional front vehicle body structure, and thus the structure is not complicated. Further, the front vehicle body structure can transmit the impact at the time of the collision to the side member by the radiator support side regardless of the vehicle type or the type of the collision, and the side member can absorb the impact.

  The first load transmitting member may be configured integrally with an apron upper member obtained by extending a conventional apron upper member to the bumper side, or may be configured separately from the apron upper member. The second load transmission member may be configured integrally with a suspension member obtained by extending a conventional suspension member to the bumper side, or may be configured separately from the suspension member. The range in which the bumper beam attached to other vehicles is located along the vertical direction refers to the bumper beam (including collision prevention bumpers for large vehicles) attached to various types of vehicles, from light cars and sports cars to large trucks. It is a range located in the vertical direction. In other words, light cars and sports cars have a low bumper beam position, and large trucks have a high bumper beam position, so the height range to cover the bumper beam from a low position to a high position corresponding to the various vehicle types. It is.

  In the front body structure of this vehicle, by making the proof stress of the attachment location between the radiator support side and the side member equal to or greater than the deformation load of the side member itself, the radiator support side is moved from the side member by the impact that the attachment location receives at the time of collision. The load generated on the radiator support side can be transmitted to the side member without detachment. Further, in this front body structure, the deformation load characteristics of the first load transmission member and the apron upper member are equivalent to the deformation load of the side member itself even when an impact is received at the highest position where the bumper beam of another vehicle exists. The first load transmitting member and the apron upper member firmly support the upper portion of the radiator support side and generate a load corresponding to the impact even when receiving an impact at the time of collision. Further, in this front vehicle body structure, the deformation load characteristics of the second load transmission member and the suspension member correspond to the deformation load of the side member itself even when an impact is received at the lowest position where the bumper beam of another vehicle exists. By applying the load so that the load is generated, the second load transmission member and the suspension member firmly support the lower portion of the radiator support side and generate a load corresponding to the impact even when receiving an impact at the time of collision. In this way, in the front body structure, the proof strength of the radiator support side itself and the mounting portion and the deformation load of the support member are set based on the deformation load of the side member. The impact received by the radiator support side can be reliably transmitted to the support member and the side member without causing the attachment location to be removed or the radiator support side to be deformed, and a load can be generated.

  The deformation load of the side member corresponds to a load (generated axial force) generated when the side member is deformed when it collides, and is set in advance by experiments, simulations, or the like.

  The vehicle front body structure of the present invention may include a bumper beam that is attached to the front end portions of the pair of left and right side members and extends to the vicinity of the left and right ends of the vehicle.

  In this vehicle front body structure, the bumper beam attached to the front end of the side member is arranged to the left and right ends of the vehicle, so that even in the case of an offset collision that collides outside the radiator support side, the radiator support of the partner vehicle The side can be received by the bumper beam, and the received impact (load) can be transmitted from the bumper beam to the side member.

  The bumper beam extending to the vicinity of the left and right ends of the vehicle includes the case where it is arranged from the left and right ends of the vehicle by a predetermined length to the position where it is arranged from the left and right ends of the vehicle to the full left and right ends. It is desirable to arrange it to a close position.

  In the front vehicle body structure of the vehicle according to the present invention, it is preferable that the vehicle body includes a pair of left and right third load transmission members provided at both ends of the bumper beam and facing the front wheels, respectively.

  In the vehicle front body structure, by providing the third load transmission members at both ends of the bumper beam, the impact received at the end of the bumper beam at the time of a collision can be received by the tire via the third load transmission member. Therefore, in this front body structure, the bumper beam does not bend backward due to the impact at the time of the collision, so that a load is generated with respect to the impact received by the bumper beam, and the load can be transmitted to the side member.

  In the front vehicle body structure of the vehicle according to the present invention, it is preferable to include a pair of left and right fourth load transmission members provided between both ends of the bumper beam and the pair of left and right side members.

  In this vehicle front body structure, the fourth load transmission member is provided between the both ends of the bumper beam and the left and right side members, so that the impact received at the end of the bumper beam at the time of a collision is passed through the fourth load transmission member. Can be received by the side member. Therefore, in this front vehicle body structure, a load is generated with respect to the impact received by the bumper beam and the load can be transmitted to the side member without the bumper beam being bent backward due to the impact at the time of collision.

  According to the present invention, the structure is not complicated, the impact received at the time of the collision can be transmitted to the side member regardless of the type of vehicle and the form of the collision, and the impact at the time of the collision can be reliably absorbed by the side member. it can.

  Embodiments of a front body structure for a vehicle according to the present invention will be described below with reference to the drawings.

  In the present embodiment, the front body structure of a vehicle according to the present invention is applied to the front body structure of a normal passenger car. In the front vehicle body structure according to the present embodiment, the first load transmission member is formed integrally with the apron upper member, and the second load transmission member is formed integrally with the front suspension member. In this embodiment, there are two forms for supporting both ends of the bumper beam, a form in which tire load transmitting members are disposed at both ends of the bumper beam, and a side member load transmitting member that connects both ends of the bumper beam and the front side member. There is a form to arrange.

  With reference to FIGS. 1-5, the front vehicle body structure 1 which concerns on this Embodiment is demonstrated. FIG. 1 is a perspective view of a front vehicle body structure according to the present embodiment. FIG. 2 is a plan view of the front vehicle body structure of FIG. 3 is a front view of the front vehicle body structure of FIG. FIG. 4 is a side view of the front vehicle body structure of FIG. FIG. 5 is a side view schematically showing each member of the front body structure according to the present embodiment.

  The front vehicle body structure 1 has a collision absorbing structure that absorbs an impact at the time of collision when colliding with a vehicle or the like. In particular, the front body structure 1 has a structure capable of absorbing an impact when it collides with a vehicle regardless of the type of the vehicle and the form of the collision. Therefore, the front body structure 1 includes front side members 2 and 2, bumper beams 3, tire load transmission members 4 and 4, radiator support sides 5 and 5, radiator support upper 6, radiator support lower 7, apron upper member 8, 8. A front suspension member 9 is provided.

  The front side members 2 and 2 are a pair of left and right members extending in the front-rear direction of the vehicle, and are disposed at positions sandwiching an engine (not shown) or the like. The front side members 2 and 2 are members for improving the strength and rigidity of the vehicle body, and are members for absorbing an impact that could not be absorbed by the front portion of the vehicle such as a bumper (not shown) during a collision. Of deformation load. This predetermined deformation load is set by a collision experiment, simulation, or the like, and corresponds to a load (generated axial force) generated when the front side members 2 and 2 are deformed when a collision occurs. The front side members 2 and 2 are deformed when a load greater than a predetermined deformation load is applied at the time of a collision, and the impact at the time of the collision is absorbed by the deformation.

  The bumper beam 3 is a member that supports the bumper and receives an impact at the time of collision, and is attached to the front end portions of the front side members 2 and 2. The yield strength of the bumper beam 3 is greater than the deformation load of the front side member 2. Therefore, when the bumper beam 3 receives an impact at the time of collision, the bumper beam 3 does not deform greatly and transmits the load generated in response to the impact to the front side members 2 and 2.

  The bumper beam 3 extends to the full width of the vehicle in the left-right direction of the vehicle, and covers the entire vehicle width region in the region that receives an impact at the time of collision. Thus, since the bumper beam 3 extends to the outside of the front side members 2 and 2, the portion extending to the outside is in a cantilever state. Therefore, tire load transmitting members 4 and 4 are respectively attached to the rear surfaces of both ends of the bumper beam 3 in order to prevent a portion extending outward of the bumper beam 3 from being bent by an impact at the time of collision. When an impact at the time of collision is received at the end of the bumper beam 3, the impact is absorbed by the tire load transmitting member 4, and even if the end of the bumper beam 3 is bent slightly backward, the impact is absorbed by the tire load transmitting member 4. (Load) is transmitted to the tire T, and the impact is absorbed by the tire T. Thus, the portion outside the front side members 2 and 2 of the bumper beam 3 itself has sufficient strength and the left and right ends are supported by the tire load transmitting members 4 and 4 and the tires T and T. Even if it receives a shock at the time of a collision, it does not bend or greatly deform, and it can firmly receive the shock at the time of a collision.

  The tire load transmission members 4 and 4 are members that support the end portion of the bumper beam 3. The tire load transmitting member 4 extends from the bumper beam 3 to the vicinity of the tire T, has a shape that slightly expands in the left-right direction and the up-down direction toward the tire T, and the surface facing the tire T is a curved surface along the tire T. is there. When the tire load transmitting member 4 receives an impact at the time of collision through the bumper beam 3, the tire load transmitting member 4 comes into contact with the tire T as the bumper beam 3 bends slightly backward. In the tire T, the tire load transmission member 4 is received and the energy of the impact is absorbed. When the tire T moves rearward, it is received by the rocker R. Further, the tire load transmission member 4 generates a load against the impact at the time of the collision, transmits the load to the bumper beam 3, and supports the bumper beam 3 from the rear. In the present embodiment, the tire load transmitting member 4 corresponds to a third load transmitting member described in the claims.

  The radiator support sides 5 and 5 are members that support a radiator (not shown), and are members that receive an impact at the time of a collision. The radiator support sides 5 and 5 are a pair of left and right, the upper ends are connected by a radiator support upper 6, and the lower ends are connected by a radiator support lower 7. The radiator is supported by a rectangular support portion formed by the pair of left and right radiator support sides 5, 5, the radiator support upper 6 and the radiator support lower 7.

  The radiator support sides 5 and 5 extend in the vertical direction of the vehicle, have a length longer than the bumper beam range A, and are disposed at positions including the bumper beam range A (see FIG. 5). Bumper beam range A is the lowest position of the bumper beam (including anti-collision bumpers provided on trucks, etc.) provided on vehicles of various types, ranging from sports cars and light vehicles to large trucks and large buses. The height range from the bumper beam to the highest bumper beam. Accordingly, the radiator support sides 5 and 5 cover the entire height region in the region that receives an impact at the time of collision, and can receive bumper beams of various vehicle types at the time of the collision. It is desirable that the bumper beam range A be a range that includes the position of the bumper beam of all vehicle types traveling on public roads, but the radiator support sides 5 and 5 housed in the engine room have height restrictions. In the case where it is not possible to cope with all vehicle types, the radiator support sides 5 and 5 are arranged to the full height limit of the engine room.

  The radiator support sides 5 and 5 are disposed at positions inscribed in the front side members 2 and 2, and are attached to the side surfaces of the front side members 2 and 2, respectively. The proof stress of this attachment location and the proof stress of the radiator support side 5 itself are more than the deformation load of the front side member 2. Therefore, if the radiator support side 5 receives an impact at the time of a collision, it does not come off from the front side member 2 before the front side member 2 is deformed or does not greatly deform itself, and is generated in response to the impact. The transmitted load can be transmitted to the front side members 2 and 2. Furthermore, apron upper members 8 and 8 are attached to the rear surfaces of the upper ends of the radiator support sides 5 and 5, respectively, and are supported by the apron upper members 8 and 8. Further, front suspension members 9 are respectively attached to the lower ends of the radiator support sides 5, 5 and supported by the front suspension members 9. In this way, the radiator support sides 5 and 5 have sufficient strength and are supported at both upper and lower ends, so that they are not bent or greatly deformed even when subjected to an impact at the time of collision. It can receive the impact at the time of collision firmly.

  The apron upper members 8 and 8 are skeleton members of the front apron and are members that support the radiator support sides 5 and 5. The apron upper members 8 and 8 are a pair of left and right, and are composed of main body portions 8a and 8a and connection portions 8b and 8b. The main body 8a is a part that forms a skeleton of the front apron, and is disposed above the tires T and T outside the suspension towers S and S. The connection portion 8 b extends from the front end of the main body portion 8 a to the rear surface of the upper end of the radiator support side 5 in order to connect to the radiator support side 5. The front end of the connection portion 8 b is attached to the rear surface of the upper end of the radiator support side 5. In the present embodiment, the connecting portion 8b corresponds to the first load transmitting member described in the claims. Incidentally, the conventional apron upper member consists only of the main body 8a.

  The deformation load of the apron upper member 8 (main body portion 8a and connection portion 8b) is not less than a value obtained by multiplying the deformation load of the front side member 2 by (b / a) (see FIG. 5). a is the distance between the central axis of the front side member 2 and the central axis of the connecting portion 8b. b is the distance between the central axis of the front side member 2 and the upper limit of the bumper beam range A. Therefore, the value obtained by multiplying the deformation load of the front side member 2 by (b / a) indicates that when the radiator support side 5 collides with a vehicle having a bumper beam at the highest position among various vehicle types, the radiator support side 5 This corresponds to the deformation load of the apron upper member 8 required when generating a load corresponding to the deformation load of 2.

  The front suspension member 9 is a member to which a front suspension (not shown) or the like is assembled, and is a member that supports the radiator support sides 5 and 5. The front suspension member 9 includes a main body portion 9a and connection portions 9b and 9b. The main body 9a is a part to which a front suspension or the like is assembled, and is disposed at the lower part of the vehicle body between the tires T and T. The connecting portions 9b and 9b extend from the left and right front ends of the main body portion 9a to the rear surfaces of the lower ends of the radiator support sides 5 and 5, respectively, in order to connect to the radiator support sides 5 and 5, respectively. The front end of the connection portion 9 b is attached to the rear surface of the lower end of the radiator support side 5. In the present embodiment, the connecting portion 9b corresponds to the second load transmitting member described in the claims. Incidentally, the conventional front suspension member consists only of the main body 9a.

  The deformation load of the front suspension member 9 (main body portion 9a and connection portions 9b and 9b) is equal to or greater than the value obtained by multiplying the deformation load of the front side member 2 by (d / c) (see FIG. 5). c is the distance between the central axis of the front side member 2 and the central axis of the connecting portion 9b. d is the distance between the central axis of the front side member 2 and the lower limit of the bumper beam range A. Therefore, the value obtained by multiplying the deformation load of the front side member 2 by (d / c) indicates that when the radiator support side 5 collides with a vehicle having a bumper beam at the lowest position among various vehicle types, the radiator support side 5 This corresponds to the deformation load of the front suspension member 9 necessary when generating a load corresponding to the deformation load of 2.

  Here, with reference to FIG. 6, the other form for supporting the both ends of the bumper beam 3 is also demonstrated. FIG. 6 is a plan view showing another embodiment for supporting both ends of the bumper beam according to the present embodiment. In this embodiment, the front vehicle body structure 1 includes side member load transmission members 14 and 14 instead of the tire load transmission members 4 and 4. In the present embodiment, the side member load transmitting member 14 corresponds to a fourth load transmitting member described in the claims.

  The side member load transmission members 14 and 14 are members that support the end portion of the bumper beam 3. The side member load transmission members 14, 14 are respectively attached between the rear surfaces of both ends of the bumper beam 3 and the outer surfaces of the front side members 2, 2. When the side member load transmitting member 14 receives an impact at the time of collision through the bumper beam 3, a load is generated with respect to the impact at the time of the collision, and the load is transmitted to the side member 2 and the bumper beam 3. Is supported from behind.

  Referring to FIG. 7, front vehicle body structure 1 when an ordinary passenger car GC having front vehicle body structure 1 and a large truck LT having a front vehicle body structure having the same configuration as front vehicle body structure 1 undergo an offset collision. The shock absorbing action in will be described. FIG. 7 is a diagram showing the positional relationship between the bumper beam and the radiator support side of both vehicles when a normal passenger vehicle having a front vehicle body structure and a large truck collide with each other according to the present embodiment.

  As shown in FIG. 7, the position of the bumper beam 3 of the ordinary passenger car GC is lower than the position of the bumper beam 3 of the large truck LT. The offset collision is a collision at a portion outside the radiator support sides 5 and 5 of each other. However, in the ordinary passenger car GC and the large truck LT, the bumper beam 3 extends to the full width of the vehicle, and the radiator support side 5 sufficiently covers the region where the counterpart bumper beam 3 is located. Therefore, in the ordinary passenger car GC, when an offset collision occurs, the end of the bumper beam 3 hits the lower part of the radiator support side 5 of the large truck LT, and the upper part of the radiator support side 5 hits the end of the bumper beam 3 of the large truck LT. That is, in the ordinary passenger car GC, the impact of the collision is received at the end of the bumper beam 3 and the upper part of the radiator support side 5.

  In the normal passenger car GC, when the impact of the collision is received at the end of the bumper beam 3, the bumper beam 3 is supported by the tire load transmission member 4 and the load generated in response to the impact is transmitted to the bumper beam. The impact energy is absorbed by the tire T. The bumper beam 3 transmits the load generated by the impact and the load from the tire load transmitting member 4 to the front side member 2 without bending at the end. In the ordinary passenger car GC, when the impact of the collision is received at the upper portion of the radiator support side 5, the radiator support side 5 is supported by the apron upper member 8 and the load generated in response to the impact is transmitted to the radiator support side 5. In the radiator support side 5, the load generated by the impact and the load from the apron upper member 8 are transmitted to the front side member 2 without detaching the attachment portion with the front side member 2 or bending the upper end portion. To do. The front side member 2 is deformed when the load transmitted from the bumper beam 3 or the radiator support side 5 exceeds its own deformation load, and the deformation absorbs the impact caused by the collision.

  According to the front vehicle body structure 1, the radiator support sides 5 and 5 are configured to include the bumper beam range A, so that they can be used against collisions with various types of vehicles from sports cars and light vehicles to large trucks. Thus, the radiator support sides 5 and 5 can receive the impact of the collision. Further, according to the front vehicle body structure 1, the bumper beam 3 is configured to fill the vehicle width, so that the bumper beam 3 collides with various types of collisions from an offset collision to a full lap collision that collides at a part of the front. Can be shocked.

  In the front vehicle body structure 1, the radiator support sides 5, 5 are supported from the rear by the apron upper members 8, 8 and the front suspension member 9, and the deformation load and the radiator support side 5 of the apron upper members 8, 8, front suspension member 9 are supported. , 5 and the front side members 2 and 2 have sufficient strength based on the deformation load of the front side members 2 and 2, so that the impact at the time of collision is firmly received by the radiator support sides 5 and 5 The load according to the impact can be transmitted to the front side members 2 and 2. Further, in the front vehicle body structure 1, both ends of the bumper beam 3 are supported from the rear by the tire load transmission members 4, 4 or the side member load transmission members 14, 14, and the strength of the bumper beam 3 is changed to the deformation load of the front side members 2, 2. Therefore, the impact at the time of collision can be firmly received by the bumper beam 3 and a load corresponding to the impact can be transmitted to the front side members 2 and 2.

  As described above, in the front vehicle body structure 1, regardless of the type of vehicle and the form of the collision, the radiator support sides 5 and 5 and the bumper beam 3 stop receiving the impact of the collision, and the load corresponding to the impact is received by the front side members 2 and 2. Can be communicated to. As a result, in the front body structure 1, the impact at the time of collision that could not be absorbed by the front bumper or the like can be reliably absorbed by the front side members 2 and 2.

  In particular, the front vehicle body structure 1 basically responds by changing the shape of the front side member, the bumper beam, the radiator support side, the apron upper member, and the front suspension member that are conventionally provided, or by changing the strength. Therefore, the structure is not complicated with respect to the conventional front body structure, and the number of parts is slightly increased.

  As mentioned above, although embodiment which concerns on this invention was described, this invention is implemented in various forms, without being limited to the said embodiment.

  For example, although the present embodiment is applied to a general ordinary passenger car, it can be applied to various vehicle types such as a light vehicle, a sports car, and a truck.

  In the present embodiment, the first load transmission member is integrated with the apron upper member, and the second load transmission member is integrated with the suspension member. However, the apron upper member and / or the suspension member are the same as the conventional one. The configuration may be such that the first load transmission member and / or the second load transmission member are separated.

  In the present embodiment, tire load transmission members (third load transmission members) or side member load transmission members (fourth load transmission members) are provided at both ends of the bumper beam, and the impact at the time of collision is received at both ends of the bumper beam. However, without providing the third load transmission member and the fourth load transmission member, the strength of the bumper beam itself may be a large strength capable of receiving an impact at the time of collision even in a cantilever state. .
