Description

Technical Field

[0001] The present invention relates to the structure of a rear component for a vehicle. More specifically, it relates to the structure of a rear component for a vehicle that is connected to a rocker and a rear pillar and extends rearward of the vehicle.

[0002] In recent years, a vehicle structure has been studied in which the skeletal structure of a vehicle is formed of castings such as aluminum, and these are joined to form a vehicle body frame. For example, Patent Document 1 discloses a structure in which left and right rear frames extending in the front-rear direction on both side portions at the rear of the vehicle, left and right sub towers, and a cross member connecting the left and right rear frames in the vehicle width direction are integrally formed by casting.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the castings described in Patent Document 1 are castings having the same shape as in the case of a rear frame, a sub tower, and a cross member formed of plate members, and the thickness of the members is large, leaving room for improvement from the viewpoint of weight reduction of the vehicle.

[0005] Therefore, an object of the present invention is to achieve weight reduction of a vehicle and improvement of strength and rigidity.

Means for Solving the Problems

[0006] The rear component member for a vehicle according to the present invention is a rear component member for a vehicle that is connected to the rear end of a rocker and a rear pillar and extends rearward of the vehicle. It is a hollow member integrally cast and is composed of a main body portion, a tower portion, a suspension portion, and a front end block. The main body portion extends in the vehicle front-rear direction and has a closed cross-section composed of an upper plate, a lower plate, an outer plate in the vehicle width direction, and an inner plate in the vehicle width direction. The front end is connected to the front end block. The tower portion is connected above the main body portion and has a space for accommodating a part of a suspension device. The suspension portion extends in the vehicle front-rear direction below the main body portion and is composed of an outer plate on the outer side in the vehicle width direction connected to the outer plate in the vehicle width direction of the main body portion, an inner plate on the inner side in the vehicle width direction connected to the inner plate in the vehicle width direction of the main body portion, and a bottom plate. The front end is connected to the front end block. The front end block is composed of a rear panel at the rear of the vehicle, a front panel at the front of the vehicle, and a plate member that connects the rear panel and the front panel in the vehicle front-rear direction. It is a closed cross-section member extending in the vehicle width direction, and the end portion on the outer side in the vehicle width direction is connected to the rear pillar and the rocker. The outer plate in the vehicle width direction of the main body portion and the outer plate of the suspension portion are connected to the rear panel, and the inner plate in the vehicle width direction of the main body portion and the inner plate of the suspension portion are connected to the front panel. This is the gist of the present invention.

[0007] Thereby, weight reduction of the vehicle and improvement of the strength and rigidity of the vehicle can be achieved. Further, the impact load at the time of a rear-end collision can be smoothly transmitted to the rocker.

[0008] In the rear component member for a vehicle according to the present invention, the rear panel may be connected to the rear surface of a rear end plate that covers the rear end surface of the rocker.

[0009] Thereby, the impact load at the time of a rear-end collision can be transmitted to the entire cross-section of the rocker.

[0010] In the rear component for a vehicle of the present invention, an arm bracket to which an arm of the suspension device is connected is provided on the outer side surface in the vehicle width direction of the main body portion and the suspension portion, and the main body portion may include a first connecting member that connects the outer side plate in the vehicle width direction and the inner side plate in the vehicle width direction in the vehicle width direction at a position where the arm bracket is provided.

[0011] Thereby, the rear component for a vehicle of the present invention can reduce the weight of the vehicle and improve the strength and rigidity of the portion where the main body portion and the arm of the suspension device are connected.

[0012] In the rear component for a vehicle of the present invention, a transfer axle mount bracket to which a transfer axle is connected is provided on the inner side surface in the vehicle width direction of the main body portion and the suspension portion, and the main body portion and the suspension portion may include a second connecting member that connects the outer side plate in the vehicle width direction and the inner side plate in the vehicle width direction in the vehicle width direction at a position where the transfer axle mount bracket is provided.

[0013] Thereby, the rear component for a vehicle of the present invention can reduce the weight of the vehicle and improve the strength and rigidity of the portion where the main body portion and the transfer axle are connected and the portion where the suspension portion and the transfer axle are connected.

Also, the left side plate 12 of the main body portion 10 and the left side plate 52 of the suspension portion 50 are connected to the front panel 78 of the front end block 70. And the outer ends in the vehicle width direction of the rear panel 77 and the front panel 78 of the front end block 70 extend outward in the vehicle width direction and are connected to the left side of the rocker 81 and the rear pillar 84.

[0042] With the above configuration, in the rear component 100, part of the impact load input to the rear member 92 during a rear-end collision flows from the right side plate 11 and the left side plate 12 of the main body portion 10 to the rear panel 77 and the front panel 78 of the front end block 70, and is transmitted from the rear panel 77 and the front panel 78 to the rocker 81 via the rear pillar 84. Also, part of the impact load during a rear-end collision flows from the right side plate 51 and the left side plate 52 of the suspension portion 50 to the rear panel 77 and the front panel 78 of the front end block 70, and is transmitted from the rear panel 77 and the front panel 78 to the rocker 81. At this time, the impact load is transmitted through the rear end plate 85 attached to the rear end surface 81E of the rocker 81 to the upper plate 81A, the lower plate 81B, the right plate 81C, the left plate 81D, and the middle rib 81F of the rocker 81.

[0043] In this way, the rear component 100 can smoothly transmit the impact load during a rear-end collision to the rocker 81. Also, the rear component 100 can transmit the impact load during a rear-end collision to the entire cross-section of the rocker 81. Thereby, the rear component 100 can achieve weight reduction of the vehicle 300 and improvement in the strength and rigidity of the vehicle 300.

[0044] Moreover, since the rear component 100 includes the first connecting members 20 to 23, it is possible to reduce the weight of the vehicle 300 and improve the strength and rigidity of the portion where the main body 10 is connected to the arm of the suspension device.

[0045] Furthermore, since the rear component 100 includes the second connecting members 25 to 27, it is possible to reduce the weight of the vehicle 300 and improve the strength and rigidity of the portion where the main body 10 is connected to the transaxle and the portion where the suspension part 50 is connected to the transaxle.
