Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a front pillar structure of a vehicle such as an automobile.
[0002]
[Prior art]
Front pillars such as passenger cars are required to have a strength that does not bend even during an offset collision. Is responsible for. Further, a pillar antenna is inserted into and removed from the front pillar, and a drain hose and the like are inserted therein.
[0003]
By the way, the pillar antenna, the drain hose, etc. are disposed in the front pillar from the front side of the front pillar reinforcement (front pillar outer side) to the back side (front pillar inner side) or vice versa. Is done.
[0004]
For example, in the case of the pillar antenna, as shown in FIG. 4, the pole of the pillar antenna is connected through the long hole 101 from the front side (front pillar outer side) to the back side (front pillar inner side) of the front pillar reinforcement 100. 102 is inserted diagonally.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional front pillar structure, a long hole through which the pole of the pillar antenna is inserted obliquely is formed in the front pillar reinforcement, so that the rigidity and strength of the front pillar reinforcement are reduced accordingly. As a result, this increased the size of the front pillar reinforcement and the thickness.
[0006]
Accordingly, an object of the present invention is to avoid the increase in size and increase in the thickness of the front pillar reinforcement by allowing the pillar antenna to pass through the front pillar without forming a long hole or the like in the front pillar reinforcement. An object of the present invention is to provide a front pillar structure of a vehicle that can perform the above.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the front pillar structure of the vehicle according to the present invention is such that the front pillar reinforcement arranged in the front pillar is divided in the longitudinal direction, and the divided end portions are overlapped and joined. In the front pillar structure of the vehicle, an opening for inserting a member is formed in the overlapping portion, and a member such as a pillar antenna is inserted into the opening while maintaining a bonding strength of the overlapping portion. The strength was able to be secured sufficiently.
Since the front pillar reinforcement is formed with a bead that also serves as a guide when the member is inserted into the opening, the rigidity of the front pillar reinforcement can be improved, and the insertion of a member such as a pillar antenna is facilitated. .
[0008]
Further, the vehicle front pillar structure according to the present invention is a vehicle front pillar structure in which a front pillar reinforcement disposed in the front pillar is divided in the longitudinal direction, and the divided end portions are overlapped and joined. An opening for inserting a member is formed in the overlapping portion by forming a beat deep in the longitudinal direction of the front pillar reinforcement with one end opened at one of the divided end portions.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a front pillar structure of a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.
[0010]
[Example]
1 is an enlarged perspective view of a main part of a front pillar structure showing an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 3 is an exploded perspective view of the front pillar structure.
[0011]
As shown in the figure, a front pillar reinforcement 4 and a front pillar ring having a substantially L-shaped cross section are formed between closed cross sections formed by a side panel outer 1 including a front pillar outer, a front pillar inner upper 2, a roof side rail inner 3 and the like. A front pillar 6 is configured by interposing the force upper 5.
[0012]
A pillar antenna 7 is passed through the front pillar 6, and a pole 7a of the pillar antenna 7 is freely inserted and removed at a junction block 8 portion attached to the side panel outer 1, and a feeder cable 7b is not shown. It is connected to a tuner such as a car radio (see FIG. 1).
[0013]
The upper end portion (divided end portion) of the front pillar reinforcement 4 and the lower end portion (divided end portion) of the front pillar reinforcement upper 5 are superposed and joined by spot welding, and the overlap portion An opening 9 for inserting the pole 7a of the pillar antenna 7 is formed.
[0014]
That is, a groove-shaped receiving port 10 is formed in a trumpet shape on the outer side of the front pillar at the upper end portion of the front pillar reinforcement 4, and at a portion facing the front pillar outer side of the front pillar reinforcement upper 5. Corresponding to the receiving port 10 (with the axes aligned), a bead 11 for improving rigidity serving as a guide for the pole 7a of the pillar antenna 7 is formed over a predetermined length in the vertical direction.
[0015]
Because of this configuration, the pole 7a of the pillar antenna 7 inserted in and out of the junction block 8 of the side panel outer 1 is guided by the bead 11 of the front pillar reinforcement upper 5, and the bead 11 It penetrates the opening 9 formed from the receiving port 10 of the front pillar reinforcement 4 and extends to the front pillar inner side.
[0016]
A feeder cable 7b connected to the pole 7a is connected to a tuner such as a car radio through a through-hole opened in a front pillar inner (not shown).
[0017]
As described above, in this embodiment, the opening 10 is effectively formed in the overlap portion of the front pillar reinforcement 4 and the front pillar reinforcement upper 5 without impairing the bonding strength, and the pole 7a of the pillar antenna 7 is inserted. Thus, the pillar antenna 7 can be passed through the front pillar 6 without making a hole in the front pillar reinforcement upper 5 or the like as in the prior art.
[0018]
As a result, the strength of the front pillar reinforcement 4 and the front pillar reinforcement upper 5 that are important in a vehicle collision or the like can be sufficiently secured.
[0019]
In the present embodiment, the bead 11 formed on the front pillar reinforcement upper 5 is made to correspond to the receiving port 10 of the front pillar reinforcement 4, so that the opening 9 is formed, so that the rigidity of the front pillar reinforcement upper 5 is improved. On the other hand, it is easy to insert the pillar antenna 7 into the opening 9.
[0020]
The opening 9 may be formed by forming the bead 11 deeply without forming the receiving port 10. Further, it is not necessary to form only the receiving port 10 and form the bead 11.
[0021]
Further, an elongated member such as a drain hose may be inserted into the opening 9 instead of the pillar antenna 7.
[0022]
Further, the present invention is not limited to the above-described embodiments, and it goes without saying that various changes such as changes in dimensions and shapes of various members and parts can be made without departing from the gist of the present invention.
[0023]
【The invention's effect】
As described above, according to the present invention , in the front pillar structure of the vehicle in which the front pillar reinforcement disposed in the front pillar is divided in the longitudinal direction, and the divided end portions are overlapped and joined, An opening for inserting a member is formed in the overlapping portion, and a member such as a pillar antenna is inserted into the opening while maintaining the bonding strength of the overlapping portion, so that the strength of the front pillar reinforcement can be sufficiently secured. The enlargement of the front pillar reinforcement and the increase in the wall thickness can be avoided.
[0024]
Also, since the front pillar reinforcement is formed with a bead that also serves as a guide when the member is inserted into the opening, the rigidity of the front pillar reinforcement can be improved, and the insertion of a member such as a pillar antenna is easy. become.
