Abstract

PROBLEM TO BE SOLVED: To reduce the deformation of a rear pillar due to the impact by forming a cross section of a reinforce, which is provided inside of a rear pillar and having a cross section larger than a side gate in the vertical direction of a vehicle, in the fore and aft direction of the vehicle into the shape along the cross section of the rear pillar in the fore and aft direction of the vehicle. SOLUTION: A reinforce 7 is provided in a rear pillar 6, and positioned between a door beam 5 inside of a front door 4 and a side gate 3. Outer dimension thereof is formed longer than the length of the side gate 3 in the vertical direction of the vehicle, and cross section is formed into a shape so as to follow a change of the inner surface shape of the rear pillar 6, namely, along the rear pillar 6. Practically, in the cross section, the reinforce 7 is bonded to the rear pillar 6 at a door beam 5 side thereof, and the reinforce 7 is a little separated from the rear pillar 6 at a side gate 3 side thereof. With this structure, rigidity is improved, and even in the case where an impact is applied to a car body, deformation can be restricted.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular cabin structure having a gated cargo bed at the rear of the cabin, for example, used for truck-type vehicles.

[0002]

2. Description of the Related Art In a conventional truck-type vehicle shown in FIG. 5, as shown in FIG. 6, there is no reinforce 107 inside a rear pillar 106 in a cabin body 101, and the reinforce 107 is shown in FIG. As described above, the structure is only a part of the rear pillar 106.

[0003]

In such a structure, as shown in FIG. 7, when an impact acts on the vehicle body from the front (see arrow W1 in FIG. 7), the rear pillar 106 pushes against the front door 104. Then, it is sandwiched between the side gate 103 and collapsed. As a result, the front door 10
4 is sunk into the rear pillar 106 and the front door 10
The door 4 cannot be easily opened. FIG.
As shown in (2), when an impact acts on the vehicle body from the rear (see the arrow W2 in the figure), the rear pillar 106 is crushed by the side gate 103, and the front door 104 is opened. The present invention has been made in view of such a situation, and an object of the present invention is to provide a vehicle cabin structure capable of reducing deformation of a rear pillar due to an impact.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a cabin structure for a vehicle in which a cabin body having a door provided with a door beam therein is disposed in front of a side gate. In this configuration, a reinforcement that is larger in the vehicle vertical direction than the side gate is provided in the rear pillar, and the cross section of the reinforcement in the vehicle front-rear direction is formed so as to conform to the cross-sectional shape of the rear pillar in the vehicle front-rear direction. The door beam referred to here is a bar-like member that is installed in the vehicle front-rear direction, and is used for reinforcement for improving the rigidity of the door. The door beam has both ends mounted inside the door. The rear pillar is located between the door and the side gate. The reinforcement provided on the rear pillar preferably has a length in the vehicle front-rear direction substantially equal to the length of the rear pillar in the vehicle front-rear direction. That is, it is preferable that the door beam and the reinforce and the reinforce and the side gate approach each other in the vehicle front-rear direction.

[0005] A bead extending in the front-rear direction of the vehicle may be formed in the reinforce. By providing this bead, the rigidity of the reinforce is further improved, deformation due to impact can be suppressed, and energy transmission due to impact can be performed smoothly. This bead is optimally provided on the longitudinal extension of the door beam. A plurality of beads may be provided at different positions in the vertical direction of the vehicle.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a vehicle cabin structure according to the present invention will be described with reference to the drawings.
In this embodiment, the vehicle cabin structure is provided in a truck-type vehicle as shown in FIG. This vehicle has a loading bed 2 on the rear side of the cabin body 1. This bed 2
Is a three-way opening in which the side gate 3 and the rear gate 91 can be opened. In addition, the loading platform 2 may be opened in any other direction.

As shown in FIG. 2, one door beam 5 is mounted inside the front door 4. The door beam 5 is attached so that its longitudinal direction is parallel to the vehicle front-rear direction. The door beam 5 has a generally used shape and material, and its attachment is also performed by a normal method.

Next, the reinforcement 7 will be described with reference to FIGS. As shown in FIG. 1 or FIG. 2, a reinforcement 7 is provided in the rear pillar 6. The reinforcement 7 is positioned so as to be sandwiched between the door beam 5 in the front door 4 and the side gate 3. The door beam 5 and the side gate 3 are both high-strength members. As shown in the figure, the outer dimension (vehicle vertical direction) of the reinforcement 7 is longer than the length of the side gate 3 in the vehicle vertical direction. That is, in the present embodiment, a large reinforce 7 is used. And Reinforce 7
Are provided with a plurality of beads 8 along the vehicle front-rear direction. The bead 8 can be formed by subjecting the reinforce to partial drawing, but may be formed by welding other members. By such a bead 8, the rigidity of the reinforce 7 is improved. One of the beads 8 is located on an extension of the door beam 5. It is preferable that the neutral axes coincide with each other in terms of strength. Then, as shown in FIGS. 2 and 3, when the front door 4 is closed, the door beam 5 and the side gate 3 are connected to the reinforcement 7 including the beads 8.
Substantially continuously through the shock-resistant structure. The term "substantially continuous in terms of the shock-resistant structure" as used herein does not necessarily mean joining by welding or the like, but refers to a case where energy is transmitted in the direction of impact when an impact is applied. A space may be formed between them.

The reinforcement 7 is, as shown in FIG.
The rear pillar 6 is formed to conform to the shape change of the inner surface. That is, the cross section of the reinforcement 7 has a shape substantially along the rear pillar 6. More specifically, in the cross section of the reinforcement 7, the door beam 5 side is joined to the rear pillar 6, and the side gate 3 side is slightly separated from the rear pillar 6. With such a structure, the rigidity of the rear pillar 6 is improved. In FIG. 3,
A seat belt member 92 is mounted inside the rear pillar 6 (lean force 7).

Since the cabin body 1 is structured as described above, when an impact is applied to the vehicle body, the energy is transmitted from the door beam 5 to the side gate 3 when the impact is directed from the front (arrow E1 in FIG. 2). When the impact is from behind, the impact is smoothly transmitted from the side gate 3 to the door beam 5 (arrow E2 in FIG. 2). Due to such energy transmission, as shown in FIG.
The rear pillar 6 is deformed. That is, deformation of the rear pillar 6 can be suppressed as compared with the related art (see FIG. 7 or FIG. 8). Therefore, it is possible to prevent the front door 4 from being opened at the time of an impact, and to improve the opening property of the front door 4 after the impact.

[0011]

According to the present invention, in a cabin structure for a vehicle in which a cabin body having a door provided with a door beam therein is disposed in front of a side gate, a reinforcement that is larger in the vehicle vertical direction than the side gate is provided in a rear pillar. Since the cross-sectional shape of the reinforce in the vehicle front-rear direction is formed along the cross-sectional shape of the rear pillar in the vehicle front-rear direction, deformation of the rear pillar due to impact can be reduced, and the entire cabin also deforms. It becomes difficult to do. Therefore, it is possible to prevent the door from being opened at the time of an impact and to improve the door opening property after the impact.

When the bead extending in the vehicle front-rear direction is formed in the above-described lean force, the rigidity of the lean force is further improved, the energy can be more smoothly transmitted by the impact, and the deformation by the impact can be further suppressed. Can be.
