China Patent Application Publication No. 113815391

Vehicle doors are often exposed to rain when they are open, so it is essential to take measures to prevent water leakage. As a measure against water leakage in vehicle doors, it is common practice in conventional vehicle doors to provide sealing parts for each gap, as in Patent Document 1 mentioned above. However, there is a problem in that the more sealing parts there are, the more the cost increases.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a door trim for a vehicle that can reduce costs while taking measures against water leakage.

In order to solve the above problems, the vehicle door trim of the present invention has the following features:
A vehicle door trim constituting a vehicle interior side of a vehicle door having a window,
comprising a window frame portion forming a window frame of the window,
A rain gutter is provided on the upper edge of the window frame section and extends in a direction intersecting the outside and outside directions of the vehicle interior, and is open at at least one end in the extending direction to allow rainwater to flow down to the side edge of the window frame section. It is characterized by the fact that a section is formed.

In the vehicle door trim disclosed in the present application, a rain gutter portion is formed on the upper edge of the window frame portion along the direction in which the upper edge extends, and the rain gutter portion allows the rain gutter portion to extend along the side edge of the window frame portion. This allows rainwater to flow downward. Therefore, according to the vehicle door trim disclosed in the present application, it is possible to suppress rainwater from flowing into the space between the window frame portion and the window glass and into the vehicle interior side of the door trim. On the other hand, since a sealing member is not required in the rain gutter portion where rainwater can be collected, the vehicle door trim disclosed in the present application can reduce the number of sealing members and reduce the number of members and cost.

For example, in the case of a vehicle door such as a sliding door in which the upper edge of the window frame extends horizontally, rainwater tends to accumulate on the upper edge of the window frame. Although the shape of the vehicle door to which the vehicle door trim disclosed in the present application can be applied is not particularly limited, the vehicle door trim disclosed in the present application is suitable for a vehicle door having a shape in which the upper edge of the window frame portion extends in the horizontal direction. It is. The location where the rain gutter drains rainwater is not limited to the outside of the window frame (the side of the vehicle door trim), but also the inside of the window frame, that is, the outside surface of the vehicle door trim (the door panel and the vehicle door trim). (between door trim).

In the above configuration, the vehicle door may be a generally rectangular sliding door, and the upper edge of the window frame portion may be formed to generally extend in a horizontal direction.

As described above, rainwater tends to accumulate on the upper edge of the door trim of the vehicle door having this configuration. Therefore, the vehicle door trim disclosed in the present application having the rain gutter portion is suitable for the vehicle door having this configuration.

In the above configuration, a wiring connecting the vehicle door, which is a sliding door, and the vehicle body is provided between the upper part of the vehicle door and the vehicle body, and the upper edge of the window frame portion is The wiring may be covered from below when the vehicle door is closed.

The upper edge of the window frame functions as a blindfold that makes it difficult to see the wiring from the vehicle compartment when the vehicle door is in the closed state. However, since the upper edge of the window frame portion protrudes toward the inside of the vehicle interior, rain tends to accumulate in the open state. The vehicle door trim disclosed in the present application having a rain gutter portion is more suitable for the vehicle door having this configuration.

In the above configuration, an upper end wall portion extends along an upper end portion of the door panel constituting the vehicle door and covers the upper end portion from the inside of the vehicle interior; a protruding part that forms an upper edge of a window frame part and has the rain gutter part formed on the upper surface side, and when the vehicle door is closed, the vehicle body, the upper end wall surface part, and the protruding part are provided. The wiring may be arranged in a space surrounded by the parts.

This vehicle door trim has a structure for hiding the wiring of the sliding door. The vehicle door trim with this configuration has a structure in which rainwater tends to collect on the top surface of the protrusion, but the rainwater gutter collects the rainwater on the top surface of the protrusion and allows it to flow down along the side edge of the window frame. It is possible to avoid a situation in which rainwater flows down from the upper edge of the window frame to the interior side of the door trim.

In the above structure, a flange portion extending from the upper end wall surface portion toward the outside of the vehicle interior may be provided, and the other rain gutter portion may be formed in the flange portion.

The vehicle door trim having this configuration can collect rainwater that has flowed in between the upper end of the door trim and the door panel, thereby preventing rainwater from flowing down along the inside of the window glass.

In the above configuration, the vehicle door trim is located on the inside of the vehicle interior of the window glass, and has an opening that penetrates in the direction of the exterior and exterior of the vehicle interior, so that the peripheral edge of the opening is the window frame portion. It can be done.

Since the vehicle door trim having this configuration does not cover the upper edge of the window glass, measures against water leakage are required on the interior side of the window glass. Therefore, the door trim disclosed in the present application including the rain gutter portion is suitable for the vehicle door trim having this configuration.

According to the present invention, it is possible to provide a door trim for a vehicle that can reduce costs while taking measures against water leakage.

A vehicle door trim 10, which is an embodiment of the vehicle door trim of the present invention, will be described with reference to FIGS. 1 to 12. As shown in FIG. 1, the vehicle door trim 10 of this embodiment (hereinafter sometimes simply referred to as "door trim 10") is box-shaped with relatively large dimensions in the front-rear direction and up-down direction, and is used by many people. It is used in a vehicle 12 that can carry and transport. The vehicle 12 includes a vehicle body 14 that forms a vehicle interior (vehicle compartment) therein, and a pair of doors 16 on one side of the vehicle body 14 for allowing a large number of people to get on and off. The door trim 10 constitutes the interior side of the door 16 for getting on and off the vehicle.

The pair of entry/exit doors 16 are sliding doors, and are configured to slide in opposite directions. Specifically, the front door 16 slides forward, and the rear door 16 slides rearward. As a result, the vehicle 12 can have one side of the vehicle body 14 widely open, making it easy for people to get on and off the vehicle. Although a detailed explanation will be omitted, the door 16 slides forward or backward while separating outward from the vehicle body 14 in the vehicle width direction. The vehicle 12 is not configured to cover the upper part of the door 16 when the door 16 is open, and the door 16 is exposed to the rain when it rains. becomes.

Incidentally, in FIG. 1, the door 16 for getting on and off is shown as a flat plate, but in reality, the upper side is curved toward the inside of the vehicle interior, and the side surface of the door 16 inside the vehicle is curved toward the inside of the vehicle. , it is difficult to get wet in the rain. However, as shown in FIG. 2, the door 16 for getting on and off is generally rectangular in shape, and the upper end extends horizontally in the front-rear direction, so rainwater tends to accumulate at the upper end. Therefore, the door trim 10 of this embodiment is characterized by a structure that takes measures against water leakage in order to cope with this problem. The door trim 10 of this embodiment will be described below, focusing on its water leakage prevention structure. Although the pair of entry/exit doors 16 are configured to partially overlap in the vehicle width direction at the center in the longitudinal direction, they have almost the same configuration other than that, so in the following description, the front The explanation will be made using the side door 16 for getting on and off. Note that in some of the drawings, directions are indicated using symbols Fr, Rr, In, Out, U, and D, which are the front side, the rear side, and the interior side of the vehicle in the vehicle width direction of the passenger door 16, respectively. , represents the outside, upper, and lower sides of the vehicle interior.

As shown in FIG. 3, the entrance/exit door 16 includes a door panel 20 that forms the framework of the entrance/exit door, a plate-shaped glass panel 22 fixed to the outside of the vehicle interior of the door panel 20, and an interior side of the door panel 20. The main body is the door trim 10 of this embodiment that covers the door trim 10 of the present embodiment. The entrance/exit door 16 has a structure in which the entire outside of the vehicle interior is covered by a glass panel 22. As shown in FIG. 2, the door panel 20 and the main door trim 10 form two generally rectangular openings 24 and 25 that penetrate in the vehicle width direction. Thereby, in the door 16 for getting on and off, a part of the glass panel 22 covering the outside of the vehicle interior of the door panel 20 functions as a window glass, and two windows 26 and 27 are formed.

The door panel 20 includes an outer panel 30 and an inner panel 32. As shown in FIGS. 3 to 5, the upper end portion 20a of the door panel 20 has a shape in which an inner panel 32 bulges toward the inside of the vehicle interior, and has a cylindrical shape extending in the front-rear direction. Specifically, the inner panel 32 has an upper surface portion 32a facing diagonally upward, a wall surface portion 32b generally extending in the vertical direction, and a lower surface portion 32c facing diagonally downward. The door trim 10 covers the upper end portion 20a of the door panel 20 from the wall surface portion 32b downward.

As shown in FIG. 2, the door trim 10 includes a portion forming the above-described opening 24, that is, a window frame portion 36 of the window 26. As shown in FIG. 3, the window frame upper edge 36a, which is the upper edge of the window frame portion 36, is substantially vertically downward (actually, the window frame upper edge 36a is slightly inclined downward toward the outer side of the vehicle interior). ) is the part that forms the surface. The door trim 10 also includes an upper end wall portion 38 that protrudes upward from the window frame upper edge portion 36a and covers the entire lower surface portion 32c of the inner panel 32 and the portion of the wall portion 32b excluding the upper end from the inside of the vehicle interior. There is. The upper end of the upper end wall portion 38 is configured such that a flange portion 38a projecting outward from the vehicle interior abuts against the wall portion 32b.

The window frame upper edge portion 36a has a shape that further projects toward the interior of the vehicle from the lower end of the upper end wall surface portion 38. This makes it difficult for passengers inside the vehicle to see the wiring that is routed between the vehicle body 14 and the door 16 when the door 16 is closed, as shown in FIG. It's for a reason. Specifically, when the door 16 for getting on and off is in the closed state, the vehicle body 14, the upper end wall portion 38, and the tip portion of the window frame upper edge portion 36a that protrudes from the lower end of the upper end wall portion 38 toward the inside of the vehicle interior. (Protrusion) 36a1, and is arranged so as to extend in the front-rear direction. Although a detailed explanation will be omitted, these wirings are inserted through a bellows-shaped wiring cover 40 with a rectangular cross section, so that they can follow the opening and closing of the door 16 for getting on and off.

As described above, when the passenger door 16 is opened during rain, the upper end has a width in the direction outside and outside the vehicle interior, as shown in FIGS. 3 to 5. It is easy to accumulate. Specifically, rainwater accumulates on the upper surface 32a of the inner panel 32, the flange 38a of the upper wall surface 38 of the main door trim 10, the upper surface of the tip 36a1 of the upper edge 36a of the window frame, and the wiring cover 40. easy. Therefore, if rainwater accumulates on the top surface of the door 16, after the door 16 is closed, the rainwater will enter between the inner panel 32 and the upper end wall 38, causing the main door trim 10 and the glass panel 22 and down the side surface of the glass panel 22 in the vehicle interior, or from the window frame upper edge 36a or the wiring cover 40 into the vehicle interior.

In consideration of the above, the door trim 10 of this embodiment has a structure that can suppress rainwater from entering the vehicle interior. Its structure will be explained with reference to FIGS. 6 to 12 in addition to FIG. 3. As shown in FIGS. 6 to 8, the door trim 10 is roughly divided into two parts. Specifically, the present door trim 10 includes a trim body member 50 that forms the majority of the present door trim 10, and a connection portion between the window frame upper edge portion 36a and the upper end wall surface portion 38 described above. and an assembly member 60 to be assembled to.

It has an upper surface portion 54 extending generally horizontally from an end on the indoor side to the outside of the vehicle interior, and a main body member standing wall portion 56 erected upward from the end portion of the upper surface portion 54 on the outside of the vehicle interior. However, an opening 58 is formed by cutting out most of the upper surface portion 54 and the lower end side of the main body member vertical wall portion 56, and the assembly member 60 is assembled into the opening 58.

As shown in FIGS. 3, 6, and 9, the assembly member 60 is a longitudinal member with a generally inverted T-shaped cross section. Specifically, the assembly member 60 includes an assembly member standing wall portion 62 that stands upwardly, an inner extending portion 64 that extends toward the passenger compartment from the lower end of the assembly member standing wall portion 62, and an assembly member standing wall portion 62 that extends upwardly. It has an outer extending portion 66 that extends from the lower end of the attached member standing wall portion 62 to the outside of the vehicle interior. This assembly member 60 is constructed by inserting the outer extending portion 66 into the opening 58 of the trim main body member 50 from the inside of the vehicle interior to bring the assembly member vertical wall portion 62 into contact with the main body member vertical wall portion 56, and The inner extending portion 64 and the outer extending portion 66 can be assembled by placing them on the back surface of the lower surface portion 52. Further, the assembly member 60 is configured such that each of both ends in the longitudinal direction (front-back direction) of the inner extension portion 64 engages with the edge of the opening 58 of the trim main body member 50 .

That is, in the door trim 10 of this embodiment, the window frame upper edge 36a is formed by the lower surface portion 52 and the upper surface portion 54 of the trim main body member 50, and the inner extension portion 64 and outer extension portion 66 of the assembly member 60. can be considered to be formed. Further, in the present door trim 10, the upper end wall surface portion 38 can be considered to be formed by the main body member standing wall portion 56 of the trim main body member 50 and the assembly member standing wall portion 62 of the assembly member 60.

The assembly member 60 is provided with rain gutter sections 70 and 72 on each of the inner extension section 64 and the outer extension section 66 for receiving rainwater. The rain gutter part 70 of the inner extension part 64 is formed along the edge of the inner extension part 64 on the inside of the vehicle interior, and includes a groove 70a extending in the longitudinal direction and a bottom surface at both ends of the groove 70a. and an opening hole 70b. As shown in FIG. 10, the groove 70a becomes deeper toward the end, and the bottom surface slopes downward from near the center toward the end.

Further, the rain gutter portion 72 of the outer extending portion 66 is formed along the edge of the outer extending portion 66 on the outside of the vehicle interior. As shown in FIG. 3, the outer side portion of the outer extension portion 66 has a U-shaped cross section that opens upward over the entire length, thereby forming a rain gutter portion 72. As shown in FIG. 11, the rain gutter portion 72 is deepened toward the ends, and the bottom surface slopes downward from near the center toward the ends.

As described above, the door trim 10 of the present embodiment includes the window frame part 36 that forms the window frame of the window 26, and the upper edge 36a of the window frame part 36 has a section extending in a direction intersecting the outside and outside directions of the vehicle interior. In addition, rain gutter portions 70 and 72 are formed at least at one end in the extending direction to allow rainwater to flow down to the side edge 36b of the window frame portion 36. As a result, the passenger door 16 to which the main door trim 10 is attached has a structure where rainwater easily accumulates as described above, but as shown in FIG. The rainwater that collects along the sides is received by the rainwater gutter section 70 on the inside of the vehicle interior, and the rainwater that has entered the back side of the main door trim 10 (between the main door trim 10 and the inner panel 32) is collected by the rainwater gutter section 72 on the outside of the vehicle interior. can be received by
