Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door mounting pillar having a sufficient torsional rigidity even when the door is excessively opened.

[0002]

[Prior art]

 As shown in FIG. 6, in the automobile 9, the front door 91 is generally attached to the front pillar 92. The rear door 93 is attached to the center pillar 94. Further, a door check 4 (see FIG. 3) is installed between each door and each pillar to hold the door in the half open position and the fully open position. By the way, since the front pillar 92 and the center pillar 94 have an important role of supporting the door, they need to have sufficient durability such as rigidity. In particular, when the door is over-opened or when the door is opened or closed with a strong force, a large load is applied to the door check portion 4 such as the door hinge and the door check arm 41. The same applies to the rear pillar 95.

Therefore, as shown in FIGS. 4 and 5, the pillar 8 is composed of a pillar outer 81 and a pillar reinforcement 82 arranged inside the pillar outer 81. A check-rein hose 83 is arranged inside the pillar-rein hose 82 to reinforce them. The check-rein hose 83 is joined to the pillar-rein hose 82 by spot welding 80. 4 and 5, reference numeral 84 is an inner panel, 85 is a weld nut, and 86 is a bolt hole.

[0004]

[Problems to be solved]

 However, the above conventional technique has the following problems. That is, the check-in reinforcement 83 has a substantially S-shaped cross section as shown in FIGS. Therefore, if a large load is applied when the door is over-opened, it cannot be effectively received, and defects such as distortion and cracking may occur at the mounting portion of the door check 4 of the pillar 8.

It is considered that the reason is that the check-rein hose 83 has an S-shape and is weak in torsional rigidity around the vertical axis with respect to the pillar-rein hose 82. The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a door mounting pillar having sufficient torsional rigidity even when the door is excessively opened.

[0006]

[Means for solving the problem]

 According to the present invention, a check-rein hose having a substantially U-shaped cross section is provided in a pillar-rein hose provided along the shape of the outer pillar of the pillar so that the cross-section of the pillar-rein hose is constrained. A door mounting pillar is characterized in that a bracket having a substantially L-shaped cross section is fixed to the door mounting side for mounting the bracket, and the bracket is also fixed to the check-rein hose.

What is most noticeable in the present invention is a door to which a check-rein hose having a substantially U-shaped cross section is provided in the pillar-rein hose so as to constrain the cross-section of the pillar-rein hose as described above, and a door check portion is mounted. This means that a bracket with a substantially L-shaped cross section was fixed to the mounting side, and this bracket was also fixed to the check-in hose.

As the check-in reinforcement, for example, a steel plate processed into a concave shape having a substantially U-shaped cross section is used. The check-rein hose is provided, for example, by spot welding so as to restrain the pillar-rein hose within the pillar-rein hose. Here, constraining the pillar-in hose means preventing the collapse of the shape of the pillar-in hose and firmly supporting and reinforcing it.

As the bracket, for example, a steel plate processed into a right-angled shape having a substantially L-shaped cross section is used. The bracket is attached and fixed to the inner side of the pillar-rein hose by spot welding, for example, above or below the check-rein hose (see Fig. 2). The relationship between the check-in reinforcement and the bracket may be either upside down or left or right as long as one end having a substantially T-shaped cross section can be formed at the end (see FIG. 2). The positions of 1 and 2 are opposite).

The door check has, for example, a door check arm and a locking tool thereof, and, for example, a locking tool having a substantially T-shaped cross section on a surface facing the check-rein hose and one end of the bracket, that is, a door mounting side. It is preferable to firmly attach and fix it via. As a result, the door mounting pillar will have even better torsional rigidity when the door is over-opened (see Fig. 3).

[0011]

[Action and effect]

 In the door mounting pillar of the present invention, the check-rein hose having a substantially U-shaped cross section is arranged in the pillar re-in hose as described above. Therefore, both ends of the check-in hose are in contact with the pillar-in hose while they are in contact with each other.

On the other hand, a bracket having a substantially L-shaped cross section is fixed to the door mounting side for mounting the door check in the pillar reinose hose and the check reinhose. Therefore, the bracket has a substantially T-shaped cross-section at one end of the check-in hose in a state of back-to-back with the check-in hose (see Fig. 2). Therefore, the rigidity of the pillar rein hose and the pillar outer is improved, and the mechanical strength such as torsional rigidity and durability are improved when the door is excessively opened.

In particular, when the door check part is attached via a locking tool having a substantially T-shaped cross section, mechanical strength such as torsional rigidity and durability are further improved. Further, in the present invention, the check-in reinforcement has a bulkhead, that is, a reinforcing material. As described above, according to the present invention, it is possible to provide a door mounting pillar having a sufficient torsional rigidity even when the door is excessively opened.

【Example】

 A door mounting pillar according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 to 3, the door mounting pillar of this example has a check-rein hose 1 having a substantially U-shaped cross section in a pillar rein hose 82 provided along the shape of a pillar outer 81 of a center pillar. The opening side 11 is provided so as to face the lower side (ground side) of the vehicle so as to constrain the cross section of the pillar reinforce 82.

Further, as shown in the figure, the bracket 2 having a substantially L-shaped cross section is fixed to the door mounting side 40 for mounting the door check 4 in the pillar reinforce hose 82, and the bracket 2 has the check-in line. Also fixed to the hose 1. As shown in FIGS. 1 and 2, the check-in hose 1 is made of a steel plate processed into a concave shape having a substantially U-shaped cross section. As shown in FIG. 2, the check-rein hose 1 supports the pillar-rein hose 82 inside the pillar-rein hose 82 by spot welding 80 and directs the opening 11 toward the lower part of the vehicle so as to reinforce (restrain). Be provided.

As shown in FIGS. 1 and 2, the bracket 2 is made of a steel plate processed into a right-angled shape having a substantially L-shaped cross section. As shown in FIG. 2, the check-in hose 1 and the bracket 2 are integrally joined to each other by spot welding 80 in a back-to-back state. Therefore, the one end portion 10 of the check-in hose 1 and the bracket 2 have a substantially T-shaped cross section. The check-rein hose 1 and the bracket 2 can be reversed in the vertical positional relationship.

As shown in FIGS. 1 to 3, the door check 4, such as the door check arm 41, has a cross section on a surface facing the one end 10 of the check-in hose 1 and the bracket 2, that is, a door mounting side 40. It is attached via a substantially T-shaped locking tool 3 and a rotating pin 31. As shown in FIG. 2, the locking tool 3 is attached and fixed by a bolt 88 so as to be back-to-back with one ends of the check-in hose 1 and the bracket 2. Here, the combination of the check-in hose 1 and the bracket 2 forms the end of the check-in hose.

As shown in FIG. 3, in the door check arm 41, one end of the inner panel 42 of the door 4 is joined to the outer panel 43 by a hemming 44. The above configuration was mainly described for the center pillar, but the same applies to the front pillar. Others are the same as the conventional one. 1 to 3, reference numeral 84 is a pillar inner panel, 85 is a weld nut for fixing the locking tool 3, 86 is a bolt hole, and 87 is a flange.

Next, the function and effect will be described. In the door mounting pillar of this example, the check-rein hose 1 having a substantially U-shaped cross section is provided in the pillar rein hose 82 with the opening side 11 facing downward in the vehicle body so as to constrain the cross section of the pillar rein hose 82. .. Therefore, both ends of the check-rein hose 1 are in contact with the inside of the pillar-rein hose 82 to restrain the pillar-rein hose 82. Here, restraining the pillar reinforcement 82 means that the shape of the check reinforcement 1 is prevented from being deformed, and the check reinforcement 1 is strongly supported and reinforced.

On the other hand, as shown in FIGS. 1 and 2, the bracket 2 having a substantially L-shaped cross section is also attached to the door mounting side 40 for mounting the door check 4 in the pillar line hose 82 and the check-in hose 1. It is fixed. Therefore, as shown in FIG. 2, the bracket 2 has a substantially T-shaped cross section in a state where the bracket 2 is back-to-back with the check-in hose 1. Therefore, the rigidity of the pillar outer 81 and the pillar ring hose 82 is improved, and the mechanical strength such as torsional rigidity and the durability are improved when the door is excessively opened.

As shown in FIGS. 1 to 3, the door check 4 is attached to the door attachment side 40 via a locking tool 3 having a substantially T-shaped cross section. Particularly, the check-rein hose 1 is attached and fixed so as to reinforce each other in a state of back-to-back with the door mounting side 40 having a substantially T-shaped cross section formed by the one end 10 and the bracket 2. Therefore, when the door is over-opened, the mechanical strength such as torsional rigidity and durability will be further improved. The reason is that the back-to-back structure is a structure capable of sufficiently receiving a large load on the door mounting side 40 even if a large load is applied to the door mounting side 40. In addition, in the present invention, the check-in reinforcement 1 has a role of a bulkhead. As described above, according to this example, it is possible to obtain a door mounting pillar having a sufficient torsional rigidity even when the door is excessively opened. This effect is because the check-in reinforcement 1 itself has a role of a bulkhead. In addition, the same effect can be obtained whether it is the front pillar or the center pillar.
