As shown in fig. 2 and 3, the door frame 1 includes a frame body 10, a weather strip holding member 20, and a decorative member 30. The frame body 10 is formed by bending (for example, roll forming) a strip-shaped sheet metal, and is formed into a shape including a body portion 11, a decorative member attachment portion 12, and a connecting portion 13 extending in the vehicle interior-exterior direction connecting the body portion 11 and the decorative member attachment portion 12 in fig. 2 and 3. The body 11 includes a lower wall 11a located below, an inner wall 11b located inside the vehicle interior, an upper wall 11c located above, and an outer wall 11d located outside the vehicle interior, and a groove 11e for attaching a weather strip is formed at the junction of the inner wall 11b and the upper wall 11c protruding toward the outside of the vehicle interior. The upper wall portion 11c and the outer wall portion 11d are overlapped and fixed at the joint portion 11 f. Thus, the lower wall portion 11a, the inner wall portion 11b, the upper wall portion 11c, and the outer wall portion 11d form a bag-like closed cross section. Further, a groove 11g is formed above the joint 11 f.
The outer wall portion 11d, the trim member mounting portion 12, and the connecting portion 13 together form an inverted concave-letter-shaped recess 14, and the recess 14 accommodates the upper end portion of the window glass DW and is fitted with a sealing member 42 for sealing the periphery of the window glass DW.
The weather strip holding member 20 is for holding the weather strip 41 and is fixed to the connecting portion 13. Specifically, the weather strip holding member 20 is formed by bending an iron plate, and includes: a facing portion 21, the facing portion 21 facing the connecting portion 13 and fixed to the connecting portion 13; a standing portion 22 that protrudes from one end of the opposing portion 21 that is close to the decorative component mounting portion 12 toward a side (in the case of fig. 2, the vehicle upper side) that intersects the opposing portion 21 and is opposite to the decorative component mounting portion 12; and a bent portion 23, the bent portion 23 being bent from the standing portion 22 toward the vehicle interior side. The weather strip holding member 20 has a plate thickness smaller than that of the frame body 10. The weather strip holding member 20 further includes an engaging portion 24, and the engaging portion 24 projects from one end of the opposing portion 21 opposite to the rising portion 22 toward a side opposite to the decorative member attachment portion 12 that intersects the opposing portion 21. As shown in fig. 2, the weather strip 41 is engaged and attached to the door frame 1 via the groove portions 11e and 11g, the engaging portion 24, and the bent portion 23, and seals a space between the door frame 1 and a vehicle body, not shown.
The decorative member 30 includes a stainless steel layer 32, and the entire outer surface of the stainless steel layer 32 is covered with a resin layer 33. The decorative member 30 covers the decorative member attachment portion 12 and the standing portion 22 from the outside of the vehicle cabin, and has a hook portion 31, and the hook portion 31 is hooked to the bent portion 23. In the present embodiment, as shown in fig. 3, the hook portion 31 includes: a surface contact portion 31a that contacts a surface 23a of the bent portion 23 on the opposite side of the surface facing the facing portion 21; and an end face contact portion 31b, the end face contact portion 31b being in contact with the end face 23b at the tip of the bent portion 23. Thereby, the upper end of the decorative member 30 is fixed to the weather strip holding member 20 by the hook portion 31, and as shown in fig. 2, the decorative member attachment portion 12 and the decorative member 30 are fixed by being bonded by the adhesive layer 34 (for example, double-sided tape).
A manufacturing process of the door frame 1 of the present embodiment will be described with reference to fig. 4. As shown in fig. 4 (a), first, the iron plate is bent (for example, roll-formed) to form the frame body 10. Then, as indicated by a black dot a in fig. 4 (a), the joint portion 11f is irradiated with laser light in the front-rear direction of the vehicle, and wire welding is performed at the joint portion 11 f. Next, as indicated by black dots B in fig. 4 (a), spot welding or line welding is performed along the front-rear direction of the vehicle at the positions where the iron plates are vertically overlapped to form the connecting portions 13. Thereby, the frame body 10 is completed.
Next, the other iron plate is bent to form the weather strip holding member 20. As shown in fig. 4 (b), the facing portion 21 is placed on the connecting portion 13, and the connecting portion 13 and the facing portion 21 are fixed by spot welding or wire welding at the black spot C. Thereby, the weather strip holding member 20 is fixed to the frame body 10.
Then, as shown in fig. 4 (c), the hooking portion 31 of the decorative member 30 is hooked to the bent portion 23 of the weather strip holding member 20, and the decorative member 30 is rotated to cover the standing portion 22 and the decorative member attachment portion 12. As shown in fig. 2, a double-sided adhesive tape is attached as an adhesive layer 34 to an inner surface of the decorative member 30 opposite to the decorative member mounting portion 12, and thus when the decorative member 30 is rotated to be in contact with the decorative member mounting portion 12, the decorative member mounting portion 12 and the decorative member 30 are fixed by the adhesive layer 34. Thereby, the manufacture of the door frame 1 is completed.
Next, the advantages of the present embodiment having the above-described configuration will be described.
(1) In the present embodiment, the weather strip holding member 20 and the decorative member 30 are separate members, and the weather strip holding member 20 is joined to the frame body 10 by welding, and the decorative member 30 is hooked on the bent portion 23 of the weather strip holding member 20, thereby integrating the frame body 10, the weather strip holding member 20, and the decorative member 30. With this configuration, since it is not necessary to integrate the weather strip holding member and the decorative member, the contact area required for fixing the weather strip holding member and the decorative member to each other in the related art can be reduced, and the width of the decorative member can be reduced accordingly, so that the design and the appearance of the decorative member can be improved. In addition, the manufacturing process of the frame mold can be simplified, and the manufacturing of the door frame 1 can be facilitated.
(2) In the present embodiment, the hook portion 31 has a surface contact portion 31a and an end surface contact portion 31b, and the end surface contact portion 31b contacts the end surface 23b at the tip end of the bent portion 23. This can restrict the displacement of the decorative member 30 in the vehicle interior/exterior direction by the end surface contact portion 31b, thereby improving the stability of the decorative member 30 and preventing the decorative member 30 from falling off.
(3) In the present embodiment, the frame body 10 and the weather strip holding member 20 are formed by bending an iron plate, and the decorative member 30 includes a stainless steel layer. Thus, the decorative member 30 exposed to the outside of the vehicle includes the stainless steel layer, so that the appearance of the decorative member 30 can be improved, and rust of the decorative member 30 can be suppressed. Further, the frame body 10 and the weather strip holding member 20 that are not exposed to the outside of the vehicle are made of iron plates, and the material cost can be reduced as compared with the case of being made of stainless steel.
(4) In the present embodiment, the weather strip holding member 20 has a plate thickness smaller than that of the frame body 10. Thus, a thin plate material is used for the weather strip holding member 20 having low rigidity requirements, and therefore, the weight and the production cost can be reduced.
(5) In the present embodiment, the connecting portion 13 and the facing portion 21 are fixed by welding. This can further reduce the production cost as compared with the case where the weather strip holding member 20 is attached by rivets or the like.
