Description

Technical Field

[0001] The present invention relates to a vehicle door structure.

Background Art

[0002] Generally, a vehicle door widely used is a door with a sash that surrounds a door glass attached to an upper part of a vehicle of a door body formed by combining a door outer panel and a door inner panel. In this type of door, in order to prevent intrusion of rainwater or the like from the outside when the door is closed, a weather strip or the like is attached between the sash and the vehicle body. And, the weather strip adheres between the sash and the vehicle body to prevent intrusion of water droplets or the like from the outside. Further, the sash is formed by joining a sash outer and a sash inner, and a glass run mounting channel for mounting a glass run for slidingly guiding a door glass, or a weather strip mounting channel (retainer) for mounting a weather strip is integrally formed or joined.

[0003] By the way, since the sash outer and the sash inner are joined, dew condensation generated due to temperature change or the like or water droplets that have intruded from a connection part or the like may stay in a hollow part formed inside and surrounded by the sash outer and the sash inner. Therefore, rust may occur inside the sash, and there is a risk that moisture containing rust will leach out from the sash and stain an outer surface of a vehicle body or the like.

[0004] Therefore, for example, in Patent Document 1, dew condensation or water that has intruded inside the sash is quickly discharged without staying, and in order to suppress rusting inside the sash, a front sash and a rear sash where a sash outer panel and a sash inner panel overlap are provided, and a technique is disclosed in which moisture is discharged by communicating a lower part inside a hollow cross-sectional part S formed by the sash outer and the sash inner to the inside of the door body through a communication passage (for example, see Patent Document 1).

Prior Art Documents

[0005] [Patent Document 1] Japanese Patent Publication No. 2000-108664 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, the technology described in Patent Document 1 does not have a drainage channel for moisture that has seeped between the sash outer and sash inner or weatherstrip mounting channel (retainer), and if the lower end of the joint at the bottom of the vehicle is open, there is a problem that so-called rust stains may seep out and stain the exterior surface of the vehicle body.

[0007] Therefore, the present invention has been made in view of the above-mentioned problems, and provides a vehicle door structure that prevents rust stains from flowing onto the exterior surface of the door sash. [Means for solving the problem]

Arrows FR shown in the drawings as appropriate indicate the front (front) of the vehicle V to which the vehicle door 1 is installed, arrow UP indicates the upward direction in a front view, and arrow LH indicates the left direction in a front view. In the following description, when using the directions of up and down, front and back, and left and right, unless otherwise specified, they refer to the up and down direction, the front and back direction in a front view, and the left and right direction in a front view of the vehicle V.

[0012] <Embodiment> The configuration of the vehicle door 1 will be explained using Figures 1 to 4. The explanation will use a vehicle door 1 mounted on the right side in a front view of the vehicle V as an example.

[0013] <Configuration of vehicle door 1> As shown in Figure 1, the vehicle door 1 is composed of an outer panel portion 10, an inner panel portion 20, a door window portion 30, a door sash portion 40, a sash retainer portion 50, a weatherstrip portion 60, and a glass run weatherstrip portion 70.

[0014] (Regarding the outer panel section 10 and the inner panel section 20) The outer panel portion 10 is a plate-shaped member that constitutes the outer panel of the vehicle door 1. The inner panel portion 20 is a plate-shaped member that constitutes the inner panel of the vehicle door 1 and is positioned further inward in the vehicle width direction than the outer panel portion 10. The outer panel portion 10 and the inner panel portion 20 are manufactured by pressing metal plates or the like. The outer panel section 10 and the inner panel section 20 are combined with each other and joined by welding or the like at the front and rear upper and lower ends of the vehicle. Furthermore, the outer panel section 10 and the inner panel section 20 are provided with drainage channels or drainage holes (not shown) to discharge any water droplets or other substances that have entered the interior to the outside.

[0015] (Regarding the door window section 30) The door window section 30 is a plate-shaped tempered glass panel mounted in the vehicle door 1 so as to be able to move up and down. When the door window section 30 is raised, it closes the door sash section 40, which will be described later. In a side view of the vehicle V, the door window section 30 has a roughly trapezoidal shape, with its front and rear edges formed to match the inclination of the door sash section 40.

[0016] (Regarding the door sash section 40) The door sash section 40 is provided on the upper part of the vehicle door 1, surrounding the door window section 30. The door sash section 40 is joined to the outer panel section 10 and the inner panel section 20 by welding or the like. The door sash section 40 is composed of an outer door sash section 41 and an inner door sash section 42. The outer door sash section 41 and the inner door sash section 42 are members processed by roll forming, for example, by bending a long sheet material such as a metal plate in stages to form a predetermined cross-sectional shape. The door sash section 40 is then constructed by joining the outer door sash section 41 and the inner door sash section 42 by hemming or the like. The door sash section 40 has glass guides, pillars, decorative shapes, grooves, reinforcing ribs, clip fitting holes, etc., which are not shown. In addition, the door sash part 40 forms a rear door sash part 43. As shown in FIG. 2, the rear door sash part 43 extends in the vehicle up-and-down direction on the vehicle rear side of the door sash part 40, and joins the upper side of the vehicle rear part of the outer panel part 10 and the inner panel part 20 on the lower side of the vehicle rear part of the door sash part 40. Also, as shown in FIG. 3, an outer sash outer surface OO as an outer surface in the vehicle width direction of the outer door sash part 41 and an inner sash outer surface IO as an inner surface in the vehicle width direction of the inner door sash part 42 are formed as appearance surfaces that come into contact with people's eyes on the door sash part 40. Further, on the door sash part 40, an outer sash inner surface OI of the outer door sash part 41 and an inner sash inner surface II of the inner door sash part 42 are formed as surfaces that do not come into contact with the eyes as inner surfaces formed by joining and surrounding the outer door sash part 41 and the inner door sash part 42. In addition, an internal space RS is formed inside the door sash part 40 by a space surrounded by the outer door sash part 41 and the inner door sash part 42, or a space surrounded by the inner door sash part 42 by bending or the like. The internal space RS discharges water droplets TD that have entered the internal space RS from a drain groove or drain hole provided in the outer panel part 10 and the inner panel part 20 to the outside through the inside of the door panel formed by being surrounded by the outer panel part 10 and the inner panel part 20.

[0017] (Regarding the sash retainer part 50) As shown in Fig. 2, the sash retainer portion 50 extends in the vehicle up-and-down direction and is fixed in contact with the inner door sash portion 42a, and holds a weather strip portion 60 (not shown in Fig. 2) to be described later. Specifically, the sash retainer portion 50 is joined by welding or the like to the inner door sash portion 42a, which is the surface of the inner door sash portion 42 formed in the rear door sash portion 43 and facing the rear side of the vehicle. The sash retainer portion 50 is formed by processing a metal plate or the like, and folds are provided on both side portions in the vehicle width direction for holding the weather strip portion 60 from the upper end to the lower end of the sash retainer portion 50 in the vehicle. The lower end portion of the sash retainer portion 50 in the vehicle has an inclination from the outer side in the vehicle width direction toward the upper side in the vehicle width direction. As shown in Fig. 3, a minute space IS having a minute interval is formed between the sash retainer portion 50 and the inner door sash portion 42a. Specifically, the minute space IS is an unintended gap formed because the surfaces of the respective members are non-uniform when the inner sash outer surface IO of the inner door sash portion 42a and the sash retainer portion 50 are brought into contact and joined. The minute space IS is formed on the inner sash outer surface IO, which is an appearance surface that can be seen by people. In addition, a drain portion WS (shown within the two-dot chain line in Fig. 2) is formed at the lower end portion of the sash retainer portion 50 in the vehicle. The configuration of the drain portion WS will be described later.

[0018] (Regarding the weather strip portion 60) The weather strip portion 60 is disposed so as to surround the periphery on the inner side in the vehicle width direction of the vehicle door 1 from the inner panel portion 20 to the door sash portion 40 in order to prevent intrusion of rainwater or the like into the vehicle door 1 from the inner side in the vehicle width direction. The weather strip portion 6 is molded from a soft resin or a rubber material or the like, and in the sash retainer portion 50, it is fitted and fixed to the fold provided in the sash retainer portion 50. Further, in the inner door sash portion 42 and the inner panel portion 20, the weather strip portion 60 is fixed by clips or the like not shown.

[0019] (Regarding the glass run weatherstrip section 70) The glass run weatherstrip section 70 is molded from a soft resin or rubber material and is arranged to surround the door window section 30. The glass run weatherstrip section 70 has a U-shaped cross-section that sandwiches the door window section 30 from both sides. The glass run weatherstrip section 70 is fixed to the inner door sash section 42 by clips or the like (not shown). Furthermore, in the glass run weatherstrip portion 70, an internal space RSg is formed between the inner door sash portion 42 and the glass run weatherstrip portion 70 on the outer peripheral side that does not come into contact with the door window portion 30.

[0020] <Configuration of the drainage section WS> The configuration of the drainage section WS will be explained using Figures 2 and 3.

[0021] As shown in Figure 2, the drain section WS is composed of a door sash section 40, a sash retainer section 50, a paint sealer PS, and drain holes WH. Specifically, the drain section WS is composed of an inner door sash section 42a, a sash retainer section 50 joined to the rear side of the vehicle of the inner door sash section 42a by welding or the like, a paint sealer PS that seals the gap between the inner door sash section 42a and the sash retainer section 50, and drain holes WH and WHg provided on the inner door sash section 42a side facing the inner door sash section 42a and the sash retainer section 50.

[0022] (About Paint Sealer PS) Paint sealer PS is a resin or similar substance that is applied to or used to fill in joints and small gaps in sheet metal. Paint sealer PS is applied continuously without gaps from the inside in the vehicle width direction, through the lower part of the vehicle, to the outside in the vehicle width direction, so as to seal the gap between the sash retainer portion 50 and the inner door sash portion 42a. Specifically, as shown by the thick solid and thick dashed lines in Figure 2, at the lower end of the sash retainer portion 50, the paint sealer PS is applied downward along the outer edge in the vehicle width direction above the drain hole WH, continuously through the lower end of the vehicle without gaps, and then upward along the inner edge in the vehicle width direction, up to the part of the vehicle above the drain hole WH provided in the inner door sash portion 42a. Furthermore, as shown in Figure 3, the paint sealer PS is applied to the boundary between the inner sash outer surface IO of the inner door sash portion 42a and the sash retainer portion 50 to fill the gap.

[0023] (Regarding drainage holes WH and WHg) The drain hole WH is, for example, a round hole located in the lower part of the inner door sash portion 42a of the internal space RS, and penetrates the inner door sash portion 42a from the rear side to the front side of the vehicle. In other words, the drain hole WH penetrates toward the internal space RS formed by the inner surface II of the inner sash. The drain hole WHg is formed in a shape that extends further through the inner door sash portion 42. A glass run weatherstrip portion 70 is provided on the vehicle front side of the drain hole WHg. The drain holes WH and WHg overlap when viewed from the front of the vehicle, and are formed to penetrate the inner door sash portion 42a and the inner door sash portion 42, and to penetrate toward the internal space RSg provided in the glass run weatherstrip portion 70. Furthermore, paint sealer PS is applied to both sides in the vehicle width direction and to the lower side of the vehicle around the drain hole WH, and the drain hole WH is located below the upper end of the paint sealer PS application.

[0024] <Effects and Actions> The operation of the door sash portion 40 of the vehicle door 1 according to this embodiment, which is configured as described above, will be explained with reference to Figures 3 and 4.

[0025] Water droplets may form on the door sash 40 due to rainwater, car wash water, condensation caused by temperature changes, etc. As shown in Figure 3, in the outer door sash section 41, water droplets TD penetrate the outer surface OO of the outer sash and the inner surface OI of the outer sash on the vehicle width side. In the inner door sash section 42, water droplets TD penetrate the outer surface IO of the inner sash and the inner surface II of the inner sash. Water droplets TD penetrate the internal space RS formed by the inner door sash section 42 and the minute space IS formed at the contact surface between the inner door sash section 42a and the sash retainer section 50 by capillary action, etc.

[0026] If water droplets TD enter the internal space RS, the water droplets TD move towards the lower side of the vehicle through the inside of the door sash section 40, which is surrounded by the inner door sash section 42, and into the interior of the vehicle door 1, which is surrounded by the outer panel section 10 and the inner panel section 20. Then, the water droplets TD are discharged to the outside of the vehicle V by drainage grooves or drainage holes provided in the outer panel section 10 and the inner panel section 20. Furthermore, the internal space RS is the surface that the inner surface II of the inner sash is in contact with, and is a surface that is not visible to the human eye. Therefore, even if the water droplets TD in the internal space RS contain rust, they move through the interior, which is not visible to the human eye, and are discharged to the outside of the vehicle V, thus the water droplets TD are discharged to the outside without soiling the exterior surface.

[0027] On the other hand, if a water droplet TD enters the microspace IS, as shown in Figure 4, the water droplet TD moves towards the lower side of the vehicle, as indicated by arrow BB, between the inner door sash portion 42a and the sash retainer portion 50, and moves to the drain portion WS located in the lower part of the microspace IS. The drain portion WS is surrounded by paint sealer PS, and the water droplet TD is stored in the drain portion WS between the inner door sash portion 42a and the sash retainer portion 50. The accumulated water droplets TD are drained from the drain hole WH provided in the inner door sash portion 42a, which is located below the upper end of the paint sealer PS coating, towards the internal space RS inside the inner door sash portion 42a, as indicated by the arrow BC. The internal space RS is the space surrounded by the inner surface II of the inner sash and is a surface that is not visible to the human eye. Therefore, even if the water droplets TD in the internal space RS contain rust, they are discharged to the outside of the vehicle V by moving through the interior, which is not visible to the human eye, thus preventing the water droplets TD from contaminating the exterior surface. Furthermore, if water droplets TD overflow from the internal space RS, the water droplets TD pass through the drain hole WHg, which penetrates from the drain hole WH towards the internal space RSg, and are drained into the internal space RSg provided in the glass run weatherstrip section 70. The water droplets TD are then discharged to the outside of the vehicle V through the drain grooves or drain holes provided in the outer panel section 10 and the inner panel section 20 via the internal space RSg.

[0028] As described above, the vehicle door 1 according to this embodiment includes a door sash portion 40 provided on the upper part of the vehicle surrounding the door window portion 30, and a sash retainer portion 50 that extends in the vertical direction of the vehicle, is fixed in surface contact with the door sash portion 40, and holds a weatherstrip portion 60 that prevents rainwater and the like from entering the inside of the vehicle door 1 in the vehicle width direction. Paint sealer PS is applied continuously without gaps around the lower side of the sash retainer portion 50, from the inside in the vehicle width direction through the lower part of the vehicle to the outside in the vehicle width direction, so as to seal the gap between the sash retainer portion 50 and the door sash portion 40. Below the upper end of the applied paint sealer PS, drainage holes WH and drainage holes WHg are provided on the side of the door sash portion 40 where the door sash portion 40 and the sash retainer portion 50 are in surface contact, surrounded by paint sealer PS on both sides in the vehicle width direction and the lower side of the vehicle. In other words, if a water droplet TD enters the minute space IS formed by the surface contact between the door sash portion 40 and the sash retainer portion 50, the water droplet TD is stored in the drain portion WS surrounded by the paint sealer PS. Then, the water droplet TD moves from the drain hole WH or drain hole WHg provided in the drain portion WS and penetrating toward the inner surface II of the inner sash to the invisible internal space RS or internal space RSg. Therefore, even if the water droplet TD remains inside for a long time and turns into rust, the vehicle door 1 can discharge the water droplet TD from the invisible internal space RS or internal space RSg without staining the exterior surface. Therefore, it is possible to prevent rust stains from flowing onto the exterior surface of the door sash.

[0029] In the embodiment of the present invention, the drain hole WH is exemplified as a round hole, but it may also be an elliptical, elongated, or rectangular slit.

[0030] Furthermore, although the sash retainer portion 50 is exemplified as being joined to the inner door sash portion 42 by welding or the like, it may also be integrally formed with the inner door sash portion 42 by roll molding or the like.

[0031] While embodiments of this invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments and includes designs and the like that do not depart from the spirit of this invention. [Explanation of symbols]
