Description

  The present invention relates to a vehicle door frame.

  Conventionally, various types of vehicle door frames have been proposed. For example, in the vehicle door frame of Patent Document 1, a clip is coupled to a decorative molding by spot welding, and a protrusion projecting outward in the vehicle width direction of the door frame is sandwiched by the clip, and the molding is attached to the door frame. It is what you wear. At this time, it has been proposed that the convex portion of the clip is locked to the concave portion of the door frame (protruding portion) to prevent the clip from coming off. Further, the door frame for a vehicle of Patent Document 2 forms a pair of leg portions extending inward in the vehicle width direction in the molding, and sandwiches the protruding portions protruding outward in the vehicle width direction of the door frame by these leg portions. The mall is attached to the door frame. At this time, it has been proposed to lock the molding protrusions of the molding (legs) to the stepped portion of the door frame (protrusion) to prevent the moldings from coming off. Both vehicle door frames can reduce the width of the molding (design width) by omitting a rivet or the like for connecting the molding to the door frame, and are excellent in assembling.

  By the way, in the vehicle door frame of Patent Document 1, since the molding and the clip are separate parts and must be spot-welded for their connection, the number of parts and the number of assembling steps are inevitably increased. Further, in the vehicle door frame of Patent Document 2, since the cross-sectional shape of the molding is constant over substantially the entire length in the longitudinal direction, for example, when adjusting the holding force for the door frame, the cross-sectional shape itself must be changed. There is a possibility, and it may be difficult to realize.

  An object of the present invention is to provide a vehicle door frame that can reduce the number of parts and the number of assembling steps, and can more easily adjust the holding force of the molding with respect to the door frame.

  In order to solve the above-mentioned problems, the invention according to claim 1 includes a glass run storage portion and a weather strip holding portion, and is formed of a plate material in a vehicle door frame that forms a window frame of a vehicle door, A frame member that forms a skeleton of the window frame; and a molding member that is formed of a plate material and forms a design surface on the outside of the vehicle. The frame member is overlapped with both edges of the plate material and extends to the outside of the vehicle. A frame-side extension portion that forms a part of the glass run storage portion; a cut-and-raised portion of one edge portion that forms the frame-side extension portion at a predetermined position in the longitudinal direction; and the other edge portion. The molding member is formed between the molding member and has an insertion portion that opens in a predetermined direction. The molding member extends inward of the vehicle and overlaps the extension portion on the frame side to form a part of the weather strip holding portion. Side extension The elastic member is formed in the molding side extension portion corresponding to the insertion portion, and is inserted into the insertion portion in a press-contact state from one direction in which the insertion portion opens to attach the molding member to the frame member. And a vehicle door frame.

  According to this configuration, the molding member is attached to the frame member by inserting the elastic piece into the insertion portion in a press-contact state from one direction in which the insertion portion opens. Therefore, the number of parts and the number of assembling steps can be reduced by eliminating the need for a separate clip and a work process for joining the clips. Further, in adjusting the holding force of the molding member with respect to the frame member, it can be easily adjusted by changing the number of the insertion portion and the elastic piece and the arrangement position thereof.

  According to a second aspect of the present invention, in the vehicle door frame according to the first aspect, the insertion portion opens toward the vehicle outer side, and the elastic piece faces the insertion portion to the vehicle inner side. The gist is to extend toward

  According to the configuration, when the molding member is attached to the frame member, the elastic piece is inserted into the insertion portion by moving the molding member toward the vehicle inner side with respect to the frame member. Since the molding member can be attached to the frame member, the assembling property can be further improved.

  According to a third aspect of the present invention, in the vehicle door frame according to the first aspect, the insertion portion opens along a longitudinal direction of the frame member, and the elastic piece faces the insertion portion. A vehicle door frame that extends along the longitudinal direction of the molding member.

  According to this configuration, when the molding member is attached to the frame member, the elastic piece is inserted into the insertion portion by moving the molding member along the longitudinal direction with respect to the frame member. The molding member can be attached to the frame member. In particular, when the frame member or the like is bent and formed into an arcuate shape in the longitudinal direction, when the molding member is attached to the frame member, the movement along the longitudinal direction according to the shape of the bent portion is performed. Therefore, the molding member can be firmly held by the frame member as much as the frictional force in the bent portion.

  According to a fourth aspect of the present invention, in the vehicle door frame according to any one of the first to third aspects, the elastic piece has two top portions that are in pressure contact with the other edge portion forming the insertion portion. And has a distal end portion connected to one top portion on the distal end side and a proximal end portion connected to the other top portion on the proximal end side, and both ends of the cut and raised portion are elastically formed. The gist is pinching.

  According to the same configuration, the elastic piece uses the repulsive force caused by the two top portions being in pressure contact with the other edge portion forming the insertion portion, and at the distal end portion and the proximal end portion, The molding member is attached to the frame member by elastically holding both ends of the cut and raised portion. Therefore, the elastic piece not only prevents the molding member from coming off from the frame member, but also prevents the molding member from being too close to the frame member by being overinserted in the insertion portion.

  In the present invention, it is possible to provide a vehicle door frame that can reduce the number of parts and the number of assembling steps, and can more easily adjust the holding force of the molding with respect to the door frame.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
FIG. 2 is a side view of the upper structure of the vehicle door to which the vehicle door frame according to the present embodiment is applied as viewed from the vehicle width direction outer side (vehicle outer side). As shown in the figure, a vehicle door 1 supported on a side portion of a vehicle body includes a door body 2 constituting a lower portion thereof. The door body 2 is a bag-like structure in which a door outer panel constituting the door outer plate and a door inner panel (not shown) constituting the door inner plate are combined, and can be protruded from an upward opening. Door window glass DW and the like are installed.

  Further, the vehicle door 1 includes a door frame 5 that is attached to the upper end portion of the door body 2 and constitutes a window frame of the vehicle door 1 (that is, a frame of the door window glass DW). The door frame 5 is fixed to the door body 2 (for example, a door inner panel) on the rear side of the vehicle and extends in the vehicle height direction. The door frame 5 is fixed to the door body 2 on the front side of the vehicle and the upper end of the vertical column 5a. And an upper edge portion 5b having a substantially arcuate shape that is connected to the bottom, and is opened downward. The vehicle door 1 of the present embodiment is a front door, and the upper edge portion 5b and the upright column portion 5a of the door frame 5 are arranged corresponding to the A pillar and B pillar of the vehicle body.

  The skeletons of the upright column portion 5a and the upper edge portion 5b are respectively composed of frame members 6 and 10 having a constant cross section formed by roll forming a plate material such as a steel plate. And the decoration member 7 which covers the vehicle outer side and forms the design part is attached to the frame member 6 of the upright column part 5a above the belt line BL as the upper end of the door body 2, and the upper edge A molding member 20 is attached to the frame member 10 of the portion 5b, similarly above the belt line BL and covering the outside of the vehicle to form a design portion thereof. The molding member 20 has a constant cross-sectional shape formed by roll-forming a plate material such as a rust-proof steel plate. The design portion of the decorative member 7 is gradually changed in width as it is displaced in the vehicle height direction to improve the design. The molding member 20 extends to the upper side so as to cover the upper end of the decorative member 7. This is to enhance the design by emphasizing the contour line extending in the vehicle front-rear direction of the door frame 5.

  1A and 1B are cross-sectional views (cross-sectional views taken along lines AA and BB in FIG. 3B) at different positions in the longitudinal direction of the upper edge portion 5b. FIG.1 (c) is a longitudinal cross-sectional view (sectional drawing along CC line of FIG.3 (b)). As shown in the figure, the frame member 10 has a cross-sectional shape that is continuous with one edge portion 10a extending from the vehicle outer side to the vehicle inner side (vehicle width direction inner side) and the vehicle inner end of the edge portion 10a. A stepped extending wall 10b extending inward of the door frame 5 facing the door glass DW (inner side of the vehicle door), continuously extending to the inner end of the extending wall 10b, and extended outward from the vehicle. A substantially rectangular main body wall 10c that comes into contact with the extending wall 10b, and on the outer side of the door frame 5 (outside of the vehicle door) toward the base end of the edge 10a continuously from the vehicle outer end of the main body wall 10c. An extending wall 10d that extends, a first edge 10e that extends continuously from the outer end of the extending wall 10d and overlaps the outer end surface of the edge 10a, and the first edge 10e Folded from the outer edge of the vehicle and inside the edge 10a And a second edge portion 10f extending inside the vehicle in a manner that overlaps in plane integrally. The first edge portion 10e and the second edge portion 10f constitute the other edge portion.

  The frame member 10 forms a closed cross-sectional shape 11 having a substantially mouth-shaped cross section by the extending wall 10b and the main body wall 10c. The outer side of the closed cross-sectional shape 11 is bent into a substantially C-shaped cross section that is open to the side to form a first weather strip holding portion 12. Moreover, both edge parts (edge part 10a, 1st and 2nd edge part 10e, 10f) of the board | plate material piled up on 3 sheets are extended to the vehicle outer side, and the frame side extension part 13 is formed. The first edge portion 10e forming the frame side extension portion 13 is formed with a pair of incisions basically extending in this direction at a plurality of predetermined positions in the longitudinal direction as shown in FIG. In addition, a cut-and-raised portion 14 that protrudes in a trapezoidal shape is formed on the outside in accordance with both cuts. The cut-and-raised portion 14 is connected to the first edge 10e between the respective leading ends in the longitudinal direction of both cuts, and is basically in the longitudinal direction of the first edge 10e (cut) between the edge 10a. An insertion portion 15 is formed that opens in a direction orthogonal (inside / outside direction). Further, both opening ends (both inward and outward directions) of the cut-and-raised portion 14 are inclined so as to gradually expand toward the tip, thereby forming a pair of locking portions 14a and 14b.

  On the other hand, the molding member 20 is arranged on the vehicle outer side and has a design portion 21 extending from the inner side to the outer side in a cross-sectional shape, and extends to the vehicle inner side continuously from the outer end of the design portion 21 to the first edge portion. A second weather strip holding portion 22 having an approximately U-shaped cross section that is open to the inside (inside the vehicle door) and overlaps the outer end face of 10e is integrally provided. In addition, the end surface exposed to the vehicle exterior side of the design part 21 forms the design surface 21a. Further, the inner end portion of the design portion 21 is folded outward to form a folded portion 23.

  Then, the second weather strip holding portion 22 as the mall side extending portion is basically at the plurality of predetermined positions in the longitudinal direction corresponding to the insertion portion 15 as shown in FIG. A pair of notches cut out in a direction perpendicular to the direction (inside and outside of the vehicle) is formed, and an elastic piece 24 extending toward the vehicle interior facing the insertion portion 15 is formed between both notches. Prepare. The elastic piece 24 is cantilevered by the second weather strip holding portion 22 at the vehicle outer side end close to the design portion 21. The elastic piece 24 is formed in a substantially W-shaped cross section, and has a substantially V-shaped cross section as two apexes between a proximal end portion 24a and a distal end portion 24b adjacent to the design portion 21 of the elastic piece 24. It has trough parts 24c and 24d, and has a flat plate-like connecting part 24e that connects between these trough parts 24c and 24d. The distance in the inner and outer directions from the apexes of the valley portions 24c and 24d to the base end portion 24a and the distal end portion 24b is set longer than the distance in the inner and outer directions to the connecting portion 24e.

  In this structure, when the molding member 20 is attached to the frame member 10, as shown in FIG. 3A, the insertion portion 15 and the elastic piece 24 face each other in the inner and outer directions. The positions of the frame member 10 and the molding member 20 in the longitudinal direction are matched, and the molding member 20 is slid to the inside of the vehicle with respect to the frame member 10. At this time, as shown in FIG. 1B and FIG. 3B, 24 is inserted and penetrated into the insertion portion 15 in a pressure contact state, and the molding member 20 is attached to the frame member 10. At this time, as shown in FIG. 1B, the cut-and-raised portion 14 forms the insertion portion 15 by raising the plate material, and the elastic piece 24 is inserted into the insertion portion 15. The thickness in the inner and outer directions of the portion 14, the edge portion 10a, the second edge portion 10f, and the elastic piece 24 can be reduced (see FIG. 1C).

  Here, as shown in FIG. 4 in which the region Z in FIG. 1B is enlarged, the elastic piece 24 penetrating the insertion portion 15 is between the connecting portion 24e and the cut-and-raised portion 14 (first edge portion 10e). In a form having a slight gap, the two valley portions 24c and 24d are pressed against the outer surface of the edge portion 10a, and accordingly, the base end portion 24a and the distal end portion 24b repel the cut and raised portion 14 from both sides. Generate power. That is, in the elastic piece 24, the points P1 and P2 where the both valley portions 24c and 24d are respectively pressed against the outer surface of the edge portion 10a, and the base end portion 24a and the distal end portion 24b are pressed against both the locking portions 14a and 14b, respectively. The insertion portion 15 is engaged at four points P3 and P4. And the elastic piece 24 couple | bonds the frame member 10 and the molding member 20 by elastically pinching both the latching parts 14a and 14b of the raising part 14 by this repulsive force. Therefore, the elastic piece 24 inserted into the insertion portion 15 not only prevents the molding member 20 from coming off from the frame member 10, but also prevents the molding member 20 from being too close to the frame member 10 due to being excessively inserted into the insertion portion 15. To do.

  As shown in FIGS. 1 (a) and 1 (b), the first and second weather strip holders 12 and 22 constituting the weather strip holder are cross-sectioned, for example, with a rubber material over the entire length in the longitudinal direction. A uniformly formed weather strip 30 is mounted in a liquid-tight manner to prevent water from entering the first and second weather strip holding portions 12 and 22. When the vehicle door 1 is closed, the weather strip 30 is pressure-tightly pressure-bonded to the vehicle opening B to suppress water intrusion into the vehicle interior.

  On the other hand, the molding member 20 attached to the frame member 10 has a substantially U-shaped cross section that is opened to the inside by the folded portion 23, the second edge portion 10f (frame side extending portion 13), and the extending wall 10b. A glass run storage portion 31 is formed. A glass run 32 having a substantially U-shaped cross section made of, for example, a rubber material is liquid-tightly attached to the glass run storage portion 31 over the entire length in the longitudinal direction. The glass run 32 protrudes at least from the opening end having a substantially U-shaped cross section of the glass run storage portion 31, and suppresses the intrusion of water into the glass run storage portion 31. And the glass run 32 can contact elastically both the vehicle outer periphery and the vehicle inner periphery of the door window glass DW. The glass run 32 elastically holds the door window glass DW so that it can be opened and closed.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the molding member 20 is attached to the frame member 10 by inserting the elastic piece 24 into the insertion portion 15 from one direction in which the insertion portion 15 opens. The number of parts and assembly man-hours can be reduced by eliminating the need for a separate clip for attachment and a work process for coupling. Further, in adjusting the holding force of the molding member 20 with respect to the frame member 10, it can be easily adjusted by changing the number of sets of the insertion portion 15 and the elastic piece 24 and the arrangement position thereof.

  (2) In this embodiment, when the molding member 20 is attached to the frame member 10, the elastic piece 24 is inserted into the insertion portion 15 by moving the molding member 20 toward the vehicle interior with respect to the frame member 10. Since the molding member 20 can be attached to the frame member 10, the assembling property can be further improved.

  (3) In the present embodiment, the elastic piece 24 uses the repulsive force that accompanies the press contact of the valleys 24c and 24d to the edge 10a, so that the base end 24a and the tip 24b The molding member 20 is attached to the frame member 10 by elastically holding both ends (the locking portions 14a and 14b). Therefore, the elastic piece 24 not only prevents the molding member 20 from coming off from the frame member 10, but also prevents the molding member 20 from being too close to the frame member 10 by being overinserted in the insertion portion 15.

  (4) In the present embodiment, the molding member 20 is basically attached to the frame member 10 in such a manner that the plate thickness of one sheet is raised at the frame side extension portion 13. The thickness in the inner and outer directions from the cut-and-raised portion 14 to the frame-side extending portion 13 can be further reduced. As a result, the thickness of the design surface 21a (design part 21) of the molding member 20 affected by this can also be reduced.

(5) In the present embodiment, the tip surface facing the vehicle exterior side of the edge portion 10a is sandwiched so as to be covered by the first edge portion 10e and the second edge portion 10f, thereby suppressing rust generation on the tip surface. it can.
(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, only the attachment direction of the molding member 20 to the frame member 10 is changed by changing the opening direction of the insertion portion 15 and the extending direction of the elastic piece 24 of the first embodiment. Since it is a structure, the same code | symbol is attached | subjected about the same structure and the description is partially abbreviate | omitted.

  As shown in FIG. 5, the frame member 10 is basically formed with a pair of parallel cuts extending in the direction, and a cut-and-raised part 50 that protrudes in a trapezoidal shape in accordance with both cuts. Is formed. The cut-and-raised part 50 is connected to the first edge part 10e between the respective leading ends in both the in-car direction and the longitudinal direction of the first edge part 10e (notch) between the edge part 10a. An insertion portion 51 that is open to the bottom is formed. Further, both opening ends (both ends in the inner and outer directions) of the cut and raised portion 50 are inclined so as to gradually expand toward the tip, thereby forming a pair of locking portions 50a and 50b.

  On the other hand, the molding member 20 is formed with a pair of notches that are notched in the inner and outer directions and parallel to each other, and an elastic piece 52 that extends forward in the longitudinal direction facing the insertion portion 51 between the notches. Prepare. The elastic piece 52 is cantilevered by the second weather strip holding portion 22 at the vehicle outer side end close to the design portion 21. The elastic piece 52 is formed in a substantially W-shaped cross section, and has a substantially V-shaped cross section as two apexes between a proximal end portion 52a and a distal end portion 52b adjacent to the design portion 21 of the elastic piece 52. While having the trough parts 52c and 52d, it has the flat connection part 52e which connects between these both trough parts 52c and 52d. The distances in the inner and outer directions from the apexes of the valley portions 52c and 52d to the base end portion 52a and the distal end portion 52b are set longer than the distance in the inner and outer directions to the connecting portion 52e.

  In such a structure, when the molding member 20 is attached to the frame member 10, the inside and outside of the frame member 10 and the molding member 20 are arranged so that the insertion portion 51 and the elastic piece 52 face each other in the longitudinal direction. The molding member 20 is slid to the vehicle inner side with respect to the frame member 10 by matching the position in the direction.

  At this time, since the frame member 10 and the molding member 20 are bent into an arcuate shape and have curvature in the longitudinal direction (see FIG. 2), when the frame member 10 and the molding member 20 are attached, A frictional force acts on the sliding contact surface between the side extending portion 13 (first edge portion 10e) and the second weather strip holding portion 22. Since this frictional force acts strongly by the synergistic effect of the frame member 10 and the curved portion of the molding member 20, the frame member 10 and the molding member 20 are firmly held by this frictional force.

As described above in detail, according to the present embodiment, the following effects can be obtained in addition to the effects (1) and (3) to (5) in the first embodiment.
(1) In the present embodiment, when the molding member 20 is attached to the frame member 10, the elastic piece 52 is moved to the insertion portion 51 by moving the molding member 20 along the longitudinal direction with respect to the frame member 10. The molding member 20 can be attached to the frame member 10 by being inserted. At this time, since the frame member 10 and the molding member 20 are bent into a bow shape in the longitudinal direction and have a curvature in the longitudinal direction, when the molding member 20 is attached to the frame member 10, Since the movement is made along the longitudinal direction according to the shape, the molding member can be firmly held by the frame member by the frictional force in the bent portion.
