Description

[Detailed description of the invention] [Industrial application field] This invention relates to the door structure of automobiles, for example, and is particularly applicable to the outer surface of the door glass that is inserted and guided into the door so as to be slidable up and down, and the door frame or the car body. The present invention relates to a door structure in which the outer surface is located substantially on the same plane.

[Conventional technology]

BACKGROUND ART In recent years, efforts have been made to make the outer surface of a vehicle body flush with no irregularities in order to reduce air resistance and wind noise when the vehicle is running, and to improve the overall appearance of the vehicle.

The flush outer surface of the vehicle body is also applied to doors on the side of the vehicle body of automobiles, etc. Conventional door structures that achieve such flush construction include, for example, the door structure shown in Figure 6. The edge 11 of the glass 1 in the longitudinal direction of the vehicle (the rear edge in FIG. 6) has this edge 1.
A slider 20 made of synthetic resin or the like is fixed to the slider 20, which extends in the vehicle vertical direction along the door glass 1 and biases the door glass 1 toward the outside of the vehicle. The slider 20 includes a mounting part 210 having a substantially U-shaped cross section that inserts and fixes the edge 11 of the door glass, and a so-called crank-shaped mounting part 210 that is offset toward the vehicle interior from the mounting part 210 and extends substantially parallel to the door glass 1. The guide part 220 is formed integrally with a mounting part 210 having a substantially U-shaped cross section that is inserted and guided into the door glass run 4 which is bent and fitted into the door frame 3 so as to make sliding contact therewith. When the guide portion 220 of the slider 20 fixed to the edge 11 of the door glass is inserted and guided into the door glass run 4 of the door frame 3, the slider 20 offsets the door glass 1 relatively to the outside of the vehicle. Therefore, above the door belt line part 6 (see Figure 7), this sixth
As shown in the figure (double-dashed line), the outer surface 12 of the door glass 1 and the door frame outer surface 31 (or the vehicle body) indicated by the two-dot chain line in the figure are located on approximately the same plane, and The door is configured so that the side surfaces are flush with each other, and the guide portion 220 of the slider 20 slides up and down within the door glass run 4 of the door frame 3, thereby securing the door to the mounting portion 210 of the slider 20. The glass 1 is configured to move up and down.

In addition, as a conventional technology showing a door structure with a flush door structure using such a slider, for example,
There is a publication number -68313 (Utility Application No. 163653, Showa 56).

[The problem that the idea aims to solve]

Generally, a window regulator mechanism (not shown) inside the door D (see FIG. 7) is located closer to the vehicle interior than the door glass 1, and the door glass 1 is connected to the window regulator mechanism. The door glass 1 is raised and lowered by this window regulator mechanism, but due to the relationship between the vehicle body shapes, such as the curved surfaces of the door D, the door frame 3, and the door glass 1, the door glass 1 and the window regulator mechanism The vertical locus A of the linear wind regulator mechanism is shown in the dashed line inside the door D in Fig.
This differs from the upward and downward trajectory B of the door glass 1 itself, which is drawn in an arc shape with the door belt line portion as a fulcrum, and a deviation (offset amount) C occurs between the upward and downward trajectory A and B of the two in the vehicle width direction. In addition, since the ascending and descending trajectory A of the window regulator is located closer to the vehicle interior than the ascending and descending trajectory B inside the door at the lower end of the door glass 1, each elevation within the door D when the door glass 1 is raised and lowered by the window regulator is Due to the offset amount C of the trajectories A and B, the door glass 1 is raised and lowered in a state in which it is strongly pulled toward the passenger compartment via the connecting portion of the window regulator mechanism.

As a result, the slider 20 fixed to the edge 11 of the door glass 1 to guide the door glass 1 in a vertically movable manner has a slider 20 between the guide portion 220 of the door glass 1 and the door glass run 4 due to the amount of offset. The guide portion 220 of the slider 20 is strongly pressed against the door glass run 4, increasing the sliding resistance, and as a result, the force for lifting and lowering the door glass 1 increases, the lifting operability is reduced, and the guide portion 220 of the slider 20, especially The surface 240 of the door glass 1 on the vehicle interior side from the lower end, the surface 250 on the vehicle outer side from the top end of the door glass 1, and the contact portion of the door glass run 4 with the guide portion 220 are easily worn.

In addition, a slider 2 is installed on the surface of the door glass run 4.
In order to reduce the sliding resistance with the guide part 220 of the door glass run 4, a low friction coefficient material such as urethane is coated in a thin film form. The low friction coefficient material applied to the surface of the glass run 4 is also worn away, and the material (rubber, etc.) of the door glass run 4 is exposed. Since the surface 250 of the upper end of the guide portion 220 on the outer side of the vehicle is in direct sliding contact, the sliding resistance further increases, the force for lifting and lowering the door glass 1 increases, and the operability of lifting and lowering the door glass 1 further deteriorates.

Therefore, the purpose of this invention is to reduce the sliding resistance between the door glass run and the guide portion of a slider that holds the door glass and slides vertically in the door glass run when the door glass is raised and lowered.

[Means to solve the problem]

Therefore, in this invention, the door glass is raised and lowered in an arcuate trajectory with the vicinity of the door belt line as a fulcrum by a window regulator mechanism that is located inside the door and raises and lowers the door glass. The door interior vertical movement trajectory of the lower end of the door glass is located on the outside of the vehicle with respect to the vertical movement trajectory,
The slider is fixed to an edge of the door glass in the longitudinal direction of the vehicle so as to extend in the vertical direction of the vehicle, and includes a mounting portion fixed to the edge of the door glass, and a slider that is offset from the mounting portion toward the vehicle interior and attached to the door frame. and a guide portion that slides in a door glass run fitted into the door frame, and the slider shifts the door glass toward the outside of the vehicle so that the outer surface of the door glass and the outer surface of the door frame are substantially on the same plane. In the door structure, the guide portion of the slider fixed to the edge of the door glass is formed into a thin portion by cutting out the side surface of the slider near the lower end thereof on the side of the vehicle interior.

[Effect]

According to the above-mentioned means, the side surface of the guide portion of the slider fixed to the edge of the door glass near the lower end of the vehicle compartment side is cut out to form a thin portion, so that when the door glass is raised and lowered, the slider is The pressing force of the guide part against the door glass run in the vehicle width direction is reduced by the thinner wall, and the guide part can be moved with a small force when the door glass is raised and lowered.

[Example] Hereinafter, an example of this invention will be described based on the accompanying drawings.

The drawings from FIG. 1 to FIG. 5 show an embodiment of this invention. For example, as shown in FIG. (referred to as D) as an example. FIG. 1 shows a cross-section taken along the line - inside the door D, which is below the door belt line part 6 in the door D shown in FIG. The section above the belt line portion 6 has a similar cross-sectional shape, and the edge 1 of the door glass 1 in the vehicle longitudinal direction
A slider 2 made of synthetic resin or the like is fixed to the edge 11 of the door glass, and extends in the vertical direction of the vehicle along the edge 1 (in FIG. 1, the rear edge), and offsets the door glass 1 to the outside of the vehicle. The slider 2 includes a mounting part 21 having a substantially U-shaped cross section that inserts and fixes the edge 11 of the door glass, and a door glass run that is offset from the mounting part 21 toward the vehicle interior and fitted into the door frame 3. Guide part 2 slidingly contacts inside 4
It is composed of 2. The slider 2 has a guide portion 22 inserted and guided into the door glass run 4.
This allows the door glass 1 to be offset to the outside of the vehicle, and above the door belt line portion 6 of the door D shown in FIG. 5, the door glass 1 shown in FIG.
As shown in , the outer surface 12 of the door glass 1 and the outer surface 31 of the door frame 3 indicated by the two-dot chain line in the figure can be positioned on substantially the same plane, and the outer surface of the vehicle body at the door portion is flush with the outer surface 12 of the door frame 3 . By vertically sliding the guide portion 22 of the slider 2 within the door glass run 4 of the door frame 3, the door glass 1 fixed to the mounting portion 21 of the slider 2 is vertically moved. It is configured to go up and down.

In the door structure configured in this way, the first
As shown in FIGS. 4 to 4, the wall thickness of the guide portion 22 of the slider 2, that is, the guide portion 22 that comes into sliding contact with the door glass run 4, is measured near the end 23 of the surface 24 on the passenger compartment side from the lower end of the door glass 1. The guide portion 22 of the slider 2 is made thin and has a thin portion 5 formed thereon.

That is, as explained in the prior art shown in FIG. 6 and FIG. The door glass 1 and the guide portion 22 of the slider 2 move upward and downward with an arcuate trajectory, and the guide portion 22 of the door glass 1 and the slider 2 moves toward the vehicle interior door D due to the offset amount C between the upward and downward trajectory A of the window regulator mechanism and the upward and downward trajectory B of the door glass 1. This embodiment (Figs. 1 to 4) shows the inside of the door D, which is designed to relieve the force of being pressed against the door glass run 4 in the inside and outside (upper part of the door) directions. ), the thickness in the vehicle width direction of the surface 24 on the vehicle interior side at the lower end 23 of the door glass 1 that is pressed most strongly against the door glass run 4 in the guide part 22 of the slider 2 that is in sliding contact with the door glass run 4 is set to the lower end 23. A predetermined length L (see FIGS. 3 and 4) is partially shaved off toward the top of the vehicle to form a partially thinned portion 5.

When the door glass is raised and lowered, as shown in FIG. Even if the interior side surface 24 of the lower end 23 of the door glass 1 in the guide portion 22 of the slider 2 is strongly pressed against the door glass run 4 in the door D shown in FIG. As shown in FIG. 4, the lower end 23 is formed with a predetermined length L toward the top of the vehicle and a thin wall thickness in the vehicle width direction to reduce the pressing force. As a result, the sliding resistance generated between the guide portion 22 of the slider 2 and the door glass run 4 can be reduced, the lifting operation force when raising and lowering the door glass 1 can be reduced, and the lifting operability can be improved.
In order to reduce the sliding resistance between the guide part 22 of the slider 2 and the door glass run 4, it is possible to reduce the wear of the low friction coefficient material applied in a thin film on the surface of the door glass run 4. Since sliding contact can be made through the low friction coefficient material on the surface of the door glass run 4, the sliding contact surface with the guide portion 22 of the slider 2, especially the surface 24 of the lower end 23 on the passenger compartment side, and the guide portion 22 of the door glass run 4 is Durability can be improved, and good operability of raising and lowering the door glass 1 can be maintained over a long period of time.

In addition, in the above embodiments (Figs. 1 to 4),
Although the configuration in which the thin wall portion 5 is formed on the lower end 23 of the guide portion 22 of the slider 2 and the surface 24 facing the vehicle interior is shown, the lower end of the slider 2 moves toward the vehicle interior using the door belt line portion 6 as a fulcrum when the door glass 1 is raised or lowered. Since it is strongly pulled, the surface 25 on the outside of the vehicle from the top end of the door glass 1 is also pushed strongly toward the outside of the vehicle using the door belt line part 6 as a fulcrum, so that the surface 25 on the outside of the vehicle from the top of the door glass 1 also Although not shown, the thin portion 5 may be formed similarly to the embodiments shown in FIGS. 1 to 4 described above. By forming the thin wall portion 5 also on the surface 25 of the guide portion 22 of the slider 2 on the outer side of the vehicle from the upper end, the effects of the embodiments shown in FIGS. 1 to 4 described above can be more reliably obtained. be able to.

[Effect of idea]

As mentioned above, this idea involves notching the side surface of the slider's guide section near the lower end on the passenger compartment side to form a thin section, so that when the slider's guide section moves up and down the door glass, the vehicle moves toward the door glass run. The pressing force in the width direction is eased, the sliding resistance between the slider guide part and the door glass run can be reduced, and the slider guide part and the door glass run that are in sliding contact with each other can reduce wear resistance, improve durability, and raise and lower operations. You can improve your sexual performance.
