Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle door applied to a cab such as a small truck.
[0002]
[Prior art]
Generally, this type of vehicle door includes a door main body including an outer panel and an inner panel, and a door pillar provided at the front of the inner panel, and door hinges are attached to the door pillar in the vertical direction. Therefore, the door body is supported by the cab body so as to be openable and closable via the door hinge.
[0003]
A weather strip is attached to the inner panel via a mounting clip. This weather strip has an annular shape that completely surrounds the outer periphery of the inner panel, and when the vehicle door is closed, it seals the space between the vehicle door and the cab body from wind and rain, etc. And also prevents vibration of the running door.
[0004]
[Problems to be solved by the invention]
By the way, the weather strip described above is mounted not only on the inner panel mounting rim but also on the door pillar. More specifically, the mounting rim has an open annular shape, while a weather strip mounting surface is formed on the door pillar, whereby both ends of the mounting rim are connected by the mounting surface of the door pillar. Therefore, when the door pillars are assembled to the inner panel, the inner panel mounting rim and the door pillar mounting surface must be smoothly connected.
[0005]
However, since the thickness of the inner panel and the door pillar are different from each other, it is very difficult to accurately connect the mounting rim and the mounting surface so that there is no gap between the mounting rim and the mounting surface. A step will occur. Further, even if the mounting rim is partially overlapped with the mounting surface to eliminate the gap, a large gap is generated between the mounting surface and the mounting rim.
[0006]
Although the gap described above can be eliminated by filling the sealer, it takes a lot of trouble to fill the sealer, so that the assembly operation of the inner panel and the door pillar is not easy, and the cost is increased by the amount of the sealer.
Further, since the gap described above impairs the adhesion of the weather strip to the mounting surface or mounting rim and creates a gap between them, it is indispensable to fill the sealer in order to fill this gap.
[0007]
Furthermore, the mounting clip used for mounting the weather strip must be inserted into a clip hole having an inner diameter corresponding to the thickness of the mounting rim or mounting surface. For this reason, as described above, when the inner panel and the door pillar have different wall thicknesses, the size of the mounting clip with respect to the mounting rim and the mounting surface must be made different. As a result, the structure of the weather strip becomes complicated, resulting in high costs.
[0008]
The present invention has been made based on the above-described circumstances, and the object of the present invention is not only to facilitate the assembly of door pillars to the inner panel with respect to the mounting of the weather strip, but also to reduce the manufacturing cost thereof, An object of the present invention is to provide a vehicle door that can improve the quality.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, a vehicle door according to the present invention (Claim 1) is provided with a door body composed of an outer panel and an inner panel , and a front part of the inner panel, and has an upper and lower door hinge and an inner panel. A thicker door pillar, a mounting rim formed integrally with the inner panel, extending along the outer periphery of the inner panel, and having the same thickness over the entire area, and a part of the mounting rim. A pillar wrap portion provided along the door pillar and overlapped with the door pillar, and the mounting rim including the pillar wrap portion are formed at predetermined intervals in the circumferential direction and have a plurality of the same inner diameter. The clip hole and the pillar wrap portion are formed to penetrate through the overlapped door pillar portion, and the clip holes corresponding to the clip holes of the portion are respectively formed. Equipped with a large-diameter relief hole and the same size attachment clip corresponding to each clip hole, and these attachment clips are inserted into the clip hole only or both the clip hole and the relief hole, and are endlessly attached to the attachment rim. Weather strip .
[0010]
With the above-described configuration, the weather strip is mounted only on the mounting rim of the inner panel, and the assembly of door pillars to the inner panel is facilitated with respect to the mounting of the weather strip.
More specifically, all weather strip mounting clips are inserted into the same inner diameter clip hole formed in the mounting rim, and the mounting clip inserted into the mounting rim pillar wrap clip hole is a door pillar relief hole , Interference with door pillars is avoided.
[0011]
It is preferable that the peripheral edge of the mounting rim is folded back including the pillar wrap portion (Claim 2 ). In this case, the folding peripheral edge of the mounting rim serves to increase the rigidity of the inner panel.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a part of a vehicle door provided in, for example, a cab of a small truck, specifically, an inner panel 2 thereof. The inner panel 2 forms a door body of a vehicle door in cooperation with an outer panel (not shown).
A door pillar 4 is integrally joined to the front portion of the inner panel 2, and the door pillar 4 extends in the vertical direction. The door pillar 4 is thicker than the inner panel 2 and has upper and lower door hinges 6 and 8, respectively. Therefore, the door body is supported by the cab through the door hinges 6 and 8 so as to be opened and closed.
[0013]
On the other hand, a latch reinforcing member 10 is integrally joined to the rear portion of the inner panel 2, and the latch reinforcing member 10 also extends in the vertical direction in the same manner as the door pillar 4. When viewed in the vertical direction, a door latch 12 is provided at the center of the latch reinforcing member 10, and the door latch 12 can be hooked to a striker (not shown) on the cab side.
[0014]
An upper reinforcing beam 16 is disposed on the inner panel 2 below the belt line portion 14. The belt line portion 14 forms the bottom of the window frame of the door body, and a window glass (not shown) projects through the belt line portion 14.
The upper reinforcing beam 16 has a substantially rectangular closed cross-section, that is, a box shape, extends along the belt line portion 14, and both ends thereof are coupled to the upper door hinge 6 and the upper portion of the latch reinforcing member 10, respectively.
[0015]
Further, a lower reinforcing beam 18 is disposed on the inner panel 2 below the upper reinforcing beam 16, and the lower reinforcing beam 18 extends in parallel with the upper reinforcing beam 16. The lower reinforcing beam 18 is formed of a pipe member, and both ends thereof are coupled to the lower door hinge 8 and the lower portion of the latch reinforcing member 10, respectively.
The inner panel 2 is integrally formed with a mounting rim 20 for a weather strip, and this mounting rim 20 is a complete ring extending along the outer peripheral portion of the inner panel 2 as shown by a one-dot chain line in FIG. I am doing.
[0016]
That is, as shown in FIG. 2, the mounting rim 20 has a pillar wrap portion 22 extending along the outer surface of the door pillar 4, and the pillar wrap portion 22 is overlapped with the door pillar 4. A large number of clip holes 24 are formed in the mounting rim 20, and these clip holes 24 are arranged on the strip mounting line L of the mounting rim 20 at a predetermined interval and have the same inner diameter.
[0017]
In FIG. 2, reference numeral 26 indicates attachment holes for the door hinge 8, and these attachment holes 26 are formed in the door pillar 4.
An endless weather strip 28 is mounted on the mounting rim 20. More specifically, the weather strip 28 extends in close contact with the mounting rim 20, and the mounting clip is inserted into the clip hole 24 of the mounting rim 20 to be fixed to the mounting rim 20.
[0018]
Referring to FIG. 3, the mounting state of the weather strip 28 on the pillar wrap portion 22 of the mounting rim 20 is specifically shown. The mounting clip 30 of the weather strip 28 is inserted into the clip hole 24 of the pillar wrap portion 22 and passes through the door pillar 4. That is, the door pillar 4 is formed with a relief hole 32 corresponding to the clip hole 24 of the pillar wrap portion 22 at a portion where the pillar wrap portion 22 of the mounting rim 20 overlaps, and the inner diameter of these relief holes 32 is the clip hole. The diameter is larger than 24. Therefore, the attachment clip 30 inserted into the pillar wrap portion 22 can penetrate the door pillar 4 without interfering with the door pillar 4.
[0019]
Furthermore, the peripheral edge 34 of the mounting rim 20 is folded over the entire periphery, and the peripheral edge of the pillar wrap portion 22 is also superimposed on the door pillar 4.
As apparent from FIG. 3, the weather strip 28 is in tight contact constantly Kyabupira 36 of the cab side, and the weather strip 2 8 welt bayonet is attached to the end of Kyabupira 36, the weather strip 2 8 is in close contact at all times with both of the inner panel 2 and the door trim 40.
[0020]
According to the vehicle door described above, the mounting rim 20 of the inner panel 2 has a pillar wrap portion 22 to form an integral annular shape, and there are no gaps or steps in the middle of the mounting rim 20. Therefore, the weather strip 28 can be satisfactorily adhered to the mounting rim 20 without requiring filling of a sealer for filling a gap or a step, which greatly contributes to improving the quality of the vehicle door. Moreover, the integral annular shape of the mounting rim 20 increases the rigidity of the mounting rim 20 itself.
[0021]
Further, the presence of the mounting rim 20 described above facilitates the assembly of the door pillar 4 with respect to the inner panel 2, and further, since the sealer is unnecessary as described above, the manufacturing cost of the vehicle door is greatly reduced.
Since the mounting rim 20 is formed integrally with the inner panel 2, the thickness thereof is uniform over the entire longitudinal direction, and the inner diameters of the clip holes 24 can be made the same. Therefore, since the weather strip 28 only needs to be provided with the attachment clip 30 of the same size, the structure of the weather strip 28 is simplified, and the weather strip 28 can be obtained at a low cost. This also greatly contributes to reducing the manufacturing cost of the vehicle door.
[0022]
Furthermore, since the escape hole 32 of the door pillar 4 has a larger diameter than the clip hole 24, this also facilitates the assembly of the door pillar 4 to the inner panel 2 and the mounting of the weather strip 28.
Furthermore, since the peripheral edge 34 of the mounting rim 20 of the inner panel 2 is folded back, the rigidity of the inner panel 2 is further increased, which contributes to improving the quality of the vehicle door.
[0023]
The present invention is not limited to the above-described embodiment, and various modifications can be made.
The present invention is suitable for a vehicle door applied to a cab of a light truck, but is not limited thereto, and can be similarly applied to various vehicle doors.
[0024]
【The invention's effect】
As described above, according to the vehicle door of the present invention (Claim 1), since the pillar wrap portion is integrally provided on the mounting rim of the inner panel, the assembly of the door pillar with respect to the inner panel is easy. In addition, since the weather strip can be easily adhered to the mounting rim, the vehicle door can be easily assembled and the quality thereof can be improved.
[0025]
In addition, the mounting rim, including its pillar wrap, is uniform in thickness, so that the inner diameter of the mounting rim clip holes can be made the same, and the weather strip mounting clips can all be the same size. Strips can be obtained inexpensively.
The door pillar has a relief hole for the mounting clip, which is larger in diameter than the clip hole, making it easier to assemble the door pillar to the inner panel, and the peripheral edge of the mounting rim also has its pillar wrap part including by, if folded, the rigidity of the inner panel improved.
