Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the structure of an opening/closing body for automobiles, and more specifically, the structure of an opening/closing body that freely opens and closes the opening of the vehicle body, such as a lift gate of a hatchback type automobile. Regarding.

(Prior art and its problems) As disclosed in Japanese Utility Model Application No. 60-37420, this type of opening/closing body has a weather strip in which a window glass is supported by a frame member and this frame member is provided around the opening of the vehicle body. There is one that is configured so that it comes into contact with the tap.

That is, as shown in the third figure, flanges 112 are formed on the plate-shaped outer frame 111 at the tips of both side edges of an inner frame 112 having a substantially U-shaped cross section.
a, 112a are joined to form a hollow frame member 113 having a substantially rectangular cross section, and this hollow frame member 11
The periphery of the window glass 115 is adhered to the back surface 113a side of the opening/closing body 1 through the sealant 114.
10, and the flange edge 121a of the outer panel 121 and the edge 12 of the inner panel 122.
A weather strip 123 is attached to the joint with the hollow frame member 1 to form the periphery of the opening on the vehicle body 120 side.
The inner surface 113b of the weather strip 13 is in contact with the weather strip 123 to seal the interior and exterior of the vehicle. In FIG. 4, 116 is a welt that covers the joint flange portion of the hollow frame member 113, and 123 is a pillar trim.

However, in the conventional structure described above, since the inner frame 112 of the hollow frame member 113 is a single plate having a substantially U-shaped cross section, distortion in the vehicle width direction is likely to occur, and as a result, the weather strip 123 Poor contact is likely to occur between the two. Therefore, in order to prevent the occurrence of contact failure, the outer frame 11
If the thickness of the plate 2 is increased to increase the rigidity, the opening/closing body 110
The weight of the weather strip 123 increases, and the weather strip 123
If the hardness of the opening/closing body 110 is increased, there is a problem in that the opening/closing body 110 may fail to close.

Furthermore, since the contact area between the hollow seal member 113 and the weather strip 123 is configured to be directly exposed to water, if the contact failure as described above occurs, water will immediately enter the vehicle interior. This will result in

Furthermore, since the joint between the outer frame 111 and the outer frame 112 of the hollow frame member 113 protrudes toward the center of the vehicle width, the protruding portion blocks the window glass 115, narrowing the field of view from inside the vehicle. It is closed.

(Purpose of the invention) In view of the above-mentioned circumstances, an object of the present invention is to maintain an opening/closing body structure for an automobile that can improve the sealing performance with the vehicle body while maintaining the light weight of the frame member.

(Structure of the invention) For this reason, the opening/closing body structure of a vehicle according to the invention includes an outer frame having an inverted U-shaped cross section and an inner frame having an inverted U-shaped cross section, which is shallower than the outer frame, at the side edges of both frames. By having a frame member on at least both sides of the frame member, which is joined in a state where the parts are overlapped, a window glass is attached to the back surface of the outer frame of the frame member, and the area between the side edges of the inner frame is used as a sealing surface with the vehicle body, In addition to increasing the rigidity of the frame members to prevent poor contact with the weather strip on the vehicle body side, it also prevents water from directly hitting the sealing surface, and furthermore, the joint between the inner frame and outer frame is It is designed so that it does not overhang the area.

(Embodiment of the invention) The illustrated opening/closing body 20 is a lift gate attached to the rear part of the vehicle body 10 so as to be openable and closable.As shown in the second figure, the lift gate 20 includes an outer frame 21 having a substantially inverted U-shaped cross section. Similarly, the cross section is approximately inverted U.
A back surface 2 of a hollow frame member 23 formed by joining an inner frame 22 which is shaped like a letter and has a shallower bottom than the outer frame 21 at the inner end side of each side edge.
A window glass 25 is bonded to the 3a side via a sealant 24. Further, welts 26, 26 are fitted to the joints of the outer frame 21 and the inner frame 22, respectively.

On the other hand, a weather strip 14 is attached to the periphery of the rear opening 11 of the vehicle body 10 to cover the joint between the outer panel 12 and the inner panel 13, and when the lift gate 20 is closed, the inner panel of the hollow frame member 23 The weather strip 14 is arranged so as to be in contact with the bottom surface 22a of the weather strip 22.

In FIG. 2, 15 is a pillar trim, 16 is a damper hinge installed between the lift gate 20 and the vehicle body 10, and 17 is a reinforcement.

In this structure, the hollow frame member 23 is formed by forming a double frame having a substantially inverted U-shaped cross section and joining the ends of both frames, and also attaching the bottom surface 22c of the inner frame 22 to the weather surface on the vehicle body 10 side. Since the surface is in contact with the strip 14, the force applied to the bottom surface 22a of the inner frame 22 is received by both the outer frame 21 and the inner frame 22 through the joint, improving frame rigidity. At the same time, the weight of the frame as a whole can be maintained almost the same as before. In addition, since the sealing surface with the vehicle body is covered by the joint between both frames, water from the outside is blocked by this joint and does not directly enter the sealing area, improving sealing performance. I can do it. Furthermore, since the joint between the two frames fits within the space between the side edges of the outer frame 21, the view of the window glass 25 is not obstructed.

(Effects of the invention) As described above, according to the opening/closing body structure of an automobile according to the present invention, the simple structure of overlapping two U-shaped frames maintains the lightness of the frame member and improves the sealing performance with the vehicle body. It is possible to improve the
