Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of an automobile door, and particularly to a plastic door whose main body is composed of an inner panel and an outer panel made of plastic material.

(Prior art) In general, plastic materials are lighter than metal materials and have advantages such as not rusting, and as plastic technology has improved in recent years, they are inferior to metal materials in terms of strength, appearance, etc. Things that don't exist are now being manufactured. Along with this, various parts of automobiles are gradually being made of plastic, and as part of this, for example,
As shown in Japanese Patent No. 64316, attempts have been made to form automobile doors from plastic materials. In this case, the main body of the door is constructed by joining an inner panel and an outer panel, both of which are made of plastic material, and if necessary, a metal frame member is provided between the two panels. .

By the way, a triangular window is sometimes installed in the front of a car door, but in the case of a plastic door like the one mentioned above, especially when there is no window frame above the door body, how do you use this triangular window? There is a question as to whether it is appropriate to provide such a structure. In other words, it is difficult to attach a triangular window directly to the inner panel or outer panel made of plastic material in order to ensure strength, so a support frame for the triangular window is fixed to the door body and the triangular window is attached to the frame. For example, a window member made of a transparent plastic plate or the like will be installed, but in that case, the structure of the support frame to be installed on the door body is a matter of strength, ease of assembly, number of parts, etc. The question is whether it is advantageous or not, and the same problem also arises regarding the structure for attaching the window member to this support frame.

(Purpose of the invention) The present invention solves the above-mentioned problems when a triangular window is provided in a plastic door whose main body is constructed by joining an inner panel and an outer panel that are both made of plastic material. The triangular window or its support structure has excellent strength, is advantageous in terms of ease of assembly and the number of parts, and has a structure that allows for the flat surface of the vehicle body and improved external appearance. The purpose is to realize this.

(Structure of the invention) That is, in the plastic door structure for an automobile according to the invention, the door body is composed of an inner panel and an outer panel, both of which are made of plastic material, and a frame member is joined to the inner panel. In a door in which a triangular window is provided above the front part of the door body, the frame member is made to protrude above the front part of the door body to form a frame part of the triangular window consisting of a front side part and a rear part, and the above-mentioned The plastic window member that forms the triangular window is integrally formed with a U-shaped locking part on the front side and a similarly U-shaped guide part that guides the front edge of the window glass on the rear side. and the locking part on the front side is locked to the front side of the frame from the outside of the vehicle, and the guide part on the rear side is fixed to a protrusion protruding from the rear side of the frame. By fixing the window member from the inside of the vehicle with a member, the window member is attached to the outside of the vehicle in the frame portion, and a sealing member for sealing between the window glass and the window glass is disposed within the guide portion of the rear side of the window member. In addition, a sealing member is disposed between the window member and the front and rear sides of the frame portion so that the window member is located on the outside of the vehicle and is substantially flush with the window glass. . According to such a configuration, the frame member provided to reinforce the door body is also used as a support frame for the triangular window, and the front part of the window member is fixed to this frame part, and the rear part is fixed to this frame part. It can be easily and reliably attached simply by fixing it with a fixing member. Particularly, according to the present invention, the window members constituting the triangular window are disposed on the outside of the vehicle at the front and rear sides of the frame through sealing members so that they are substantially flush with the window glass. By doing so, there is no difference in level between the window member and the window glass of the triangular window, and the fixing member that fixes the rear side of the window member to the rear side of the frame serves as a guide for the rear side of the window member. Since the guide part is located on the inside of the vehicle, and a seal member is installed inside the guide part to seal between the guide part and the front edge of the window glass, even if the window member is transparent,
The fixing member is covered from the outside by the sealing member.

(Effects of the invention) As described above, according to the invention, in a plastic door for an automobile in which a triangular window is provided above the front part of the main body, the frame supporting the triangular window is a frame member for reinforcing the door main body. Since it is constructed by the above structure, a strong frame portion can be formed without requiring any special support member. Since the window member can be installed by simply locking the front part and fixing the rear part to this frame, the window member can be installed efficiently, and the front side of the window member can be fixed with bolts, etc. Since no members are used, the number of parts can be reduced accordingly. Furthermore, the step between the window member and the window glass is eliminated,
A flat surface of the car body will be realized, and the fixing member for fixing the rear side of the window member to the frame will no longer be visible from the outside, resulting in a good appearance of the car body. become. In this way, the structure of the triangular window part of a plastic door is excellent in terms of strength, ease of assembly, number of parts, appearance, etc. Moreover, since the window member is made of plastic, the front side part is easily engaged. The stop portion, the guide portion of the rear side portion, etc. can be easily formed, and a structure with excellent manufacturability can be realized.
