JP 2006-137346 A

  However, the quarter window disclosed in Patent Document 1 has a configuration in which the front frame portion serving as a division bar is exposed between the door glass and the quarter window glass in the appearance of the vehicle. . For this reason, the surface gloss of the door glass and the quarter window glass is divided by the front frame portion, and there is no sense of unity between the two glasses, which hinders the vehicle exterior design.

  In view of the above problems, an object of the present invention is to propose a structure of a quarter window capable of realizing an appearance having a sense of unity with a door glass.

  In order to solve the above-mentioned problem, the invention described in claim 1 includes a frame body that includes a one-side frame portion that supports a door glass in a window portion of a vehicle door and forms a divided window portion, and the divided window. A quarter window panel attached to the frame body so as to close a portion, wherein the quarter window panel and the frame body are both formed of a resin material, and the frame body is formed by the quarter window panel. The vehicle outside is covered.

  According to a second aspect of the present invention, the quarter window panel is molded from a resin material that transmits light, and the frame is molded from a colored resin material to which a filler is added.

  According to a third aspect of the present invention, the one end portion of the quarter window panel joined to the one side frame is partially thinned.

  According to a fourth aspect of the present invention, the one-side frame portion includes a guide groove that opens toward one side in the vehicle front-rear direction and to which a glass run is attached, and the guide groove has at least side surfaces facing each other. One side has a glass run engaging protrusion that protrudes relative to the other and engages the glass run.

  According to a fifth aspect of the present invention, the glass run engagement protrusions are provided on both side surfaces of the guide groove, and are provided only at both end portions with respect to the longitudinal direction of the guide groove.

  Furthermore, in the invention according to claim 6, when the quarter window is attached to the door, the other-side frame portion of the frame body that is disposed and joined to the frame portion of the door on the outer side in the vehicle width direction. In addition, a holding portion is provided for holding the holding portion of the weather strip that keeps watertightness between the door and the vehicle body between the frame body and the frame portion.

  In the first aspect of the invention, since the outer side of the frame body is covered with the quarter window panel, the one side frame portion that supports the door glass is not exposed in the appearance of the vehicle. In addition, the quarter window panel and the frame can be joined together with a resin material without a weather strip, and the distance between the door glass and the quarter window panel can be reduced. For this reason, it is possible to realize an appearance in which the surface gloss of the door glass and the quarter window panel is continuous, and further, it is possible to make the frame of the door and the glass flush with each other, thereby improving the vehicle exterior design.

  In invention of Claim 2, the rigidity of a frame can be improved by adding a filler. Further, it is possible to produce an effect that the colored frame body becomes an edge on the appearance of the quarter window panel that transmits light.

  In the invention according to claim 3, since the joint portion of the quarter window panel with the vertical frame is thinner than the other portions, the unevenness of the quarter window on the vehicle outer side can be reduced, contributing to the reduction of the aerodynamic resistance and wind noise of the vehicle. it can.

  In the invention according to claim 4, since the guide groove is provided with a glass run engagement protrusion that protrudes with respect to the other and is engaged with the glass run on at least one of the side surfaces facing each other, the glass run is prevented from coming off. You can be sure.

  In the invention according to claim 5, by providing the glass run engaging protrusions only at both end portions in the longitudinal direction, when the guide groove is molded by the molding die, the sliding die in the longitudinal direction can be shortened. Formability can be improved. In addition, since the glass run engaging protrusions are provided on both side surfaces of the guide groove, the glass run can be reliably prevented from coming off.

  In the invention according to claim 6, the quarter window panel and the frame body are positioned on the outer side in the vehicle width direction of the frame portion of the door, and the frame portion does not form a design surface. There is no joint between the body and the frame, and it is not necessary to fill this joint with a sealing material. In addition, the joint between the frame and the frame is positioned on the inner side in the vehicle width direction of the door, and the joint of the weather strip is held and held between the frame and the frame. Water tightness is ensured. For this reason, when the quarter window is assembled to the door, it is not necessary to fill the joint between the frame body and the frame portion with a sealant, and the assembly process can be reduced. Moreover, the concern about the sticking out of the sealing agent to the door surface is also eliminated. Here, “holding and holding” does not necessarily mean that a holding force is generated, but means that the holding portion and the frame portion are held in cooperation.

The first embodiment of the present invention will be described in detail below.

  FIG. 1 is a side view showing a lateral appearance of the vehicle 1. As shown in FIG. 1, a rear door 10 (door) included in the vehicle 1 includes a door main body 11 and a frame 12, and a space surrounded by the door main body 11 and the frame 12 is a window 10 a. It has become. The window 10a can be opened and closed by raising and lowering the door glass 15 by a window regulator device (not shown). In FIG. 1, the quarter window 20 is attached so as to divide and occupy the area of the rear portion of the window portion 10 a located behind the door glass 15. The quarter window 20 is fixedly attached to the frame portion 12 and the door main body portion 11.

  FIG. 2 is a side view of the quarter window 20 as viewed from the direction of the interior of the vehicle 1. 3 is a partial cross-sectional view taken along the line AA in FIG. 2, FIG. 4 is a partial cross-sectional view taken along the line BB in FIG. 2, and FIG.

  As shown in FIG. 2, the quarter window 20 is composed of an elongated front frame portion 21a (one side frame portion), a rear frame portion 21b (the other side frame portion), and a lower frame portion 21c. A triangular frame 21 is provided. A space surrounded by the frame body 21 becomes a divided window portion 20 a of the quarter window 20.

  Further, as well shown in FIG. 3, a flat quarter window panel 22 is joined to the frame body 21 so as to cover the frame body 21 from the outside of the vehicle and close the divided window portion 20a. The quarter window panel 22 is molded using a resin material that transmits light, and the frame body 21 is molded using a colored resin material such as black to which a filler for increasing rigidity is added. Both the quarter window panel 22 and the frame 21 are formed by using the same resin material of, for example, polycarbonate, using a two-color molding method, and are integrally joined to each other. After the molding, the quarter window panel 22 is subjected to a hard coating process, and the surface is finished to have a glossy and hard to be scratched surface.

  The front frame portion 21a has a U-shaped cross-sectional shape that opens to the front of the vehicle in FIG. 3 and includes a guide groove 21f. An elastic glass run 15a is mounted in the guide groove 21f, and the door glass 15 is guided through the glass run 15a so as to be movable up and down.

  A front end portion 22a (one end portion) of the quarter window panel 22 that covers the front frame portion 21a from the outside of the vehicle is formed thinner than the other portions of the quarter window panel 22. As a result, as shown in FIG. 3, the step D between the door glass 15 and the quarter window panel 22 in the vehicle outer direction is reduced.

  As shown in FIG. 2, in order to fix the quarter window 20 to the rear door 10, one attachment portion 27 is provided at the lower end portion of the front frame portion 21a, and two attachment portions 27 are provided at the upper and lower end portions of the rear frame portion 21b.

  As can be seen from the configurations shown in FIGS. 3, 4 and 5, the colored frame 21 such as black can be seen from the outside of the vehicle through the quarter window panel 22 that transmits light. And the effect which gives a border to the division | segmentation window part 20a of the quarter window 20 can be taken out, and it can contribute to the improvement of a vehicle external appearance design.

  Furthermore, since the quarter window panel 22 and the frame body 21 which are the main components of the quarter window 20 are both made of resin and can be joined at the time of molding, there is no need for joint parts between them and no assembly work is required. It can be made inexpensively and lightly.

(Second Embodiment)
Next, a second embodiment of the present invention will be described in detail.

  FIG. 6 is a side view showing a lateral appearance of the vehicle 101. As shown in FIG. 6, the rear door 110 included in the vehicle 101 includes a door main body 111 and a frame 112, and a space surrounded by the door main body 111 and the frame 112 serves as a window 110 a. Yes. The window 110a can be opened and closed by raising and lowering the door glass 115 by a window regulator device (not shown). In FIG. 6, the quarter window 120 is attached so as to divide and occupy the area of the rear portion of the window portion 110 a located behind the door glass 115. The quarter window 120 is fixedly attached to the frame part 112 and the door body part 111.

  FIG. 7 is a sectional view taken along line FF in FIG. 6 and shows a partial sectional view of the quarter window 120. FIG. 8 is a side view of the quarter window 120 as viewed from the direction of the passenger compartment of the vehicle 101, as viewed in the direction of arrow J in FIG. 7. Further, FIG. 9 is a GG cross-sectional view in FIG.

  First, as shown in FIG. 8, the quarter window 120 includes a triangular frame 121 composed of a long front frame portion 121 a, a rear frame portion 121 b, and a lower frame portion 121 c. A space surrounded by the frame body 121 is a divided window portion 120a.

  Next, as shown in FIGS. 7 and 8, the divided window portion 120a is closed by a flat quarter window panel 122 in which the frame 121 is joined from the outside of the vehicle. The quarter window panel 122 is molded using a resin material that transmits light, and the frame body 121 is molded using a colored resin material such as black to which a filler for increasing rigidity is added. Both the quarter window panel 122 and the frame body 121 are molded using a two-color molding method using a resin material of the same quality such as polycarbonate, and are integrated with each other.

  As shown in FIG. 7, the front frame portion 121a has a U-shaped cross-sectional shape that opens to the front of the vehicle, and includes a guide groove 121f. An elastic glass run 115a is mounted in the guide groove 121f, and the door glass 115 is guided by the guide groove 121f through the glass run 115a so as to be movable up and down.

  A glass run engaging protrusion for holding the glass run 115a in the mounting position and preventing the glass run 115a from easily falling off the guide groove 121f at the leading end of the U-shaped cross section of the guide groove 121f. 121e is formed. As the shape of the glass run engagement protrusion 121e, for example, various forms are conceivable as shown in the perspective views of FIGS. 10A to 10C as viewed in the direction of the arrow K in FIG. That is, a plurality of glass run engagement protrusions 121e are arranged at the same position on both sides (both side surfaces 121A) of the U-shape of the guide groove 121f with a predetermined length in the length direction of the guide groove 121f. In the case of (b)), the glass run engagement protrusions 121e that are continuous over the entire length of both sides of the guide groove 121f are arranged (in the case of (c)). The optimum shape may be selected in consideration of the ease of forming the entire quarter window 120. Thus, since the glass run engagement protrusions 121e are provided on both side surfaces 121A of the guide groove 121f, the glass run 115a can be reliably prevented from coming off. The glass run engagement protrusion 121e is not necessarily provided on both side surfaces 121A. For example, the guide groove 121f protrudes from at least one side surface 121A of the side surfaces 121A facing each other to the other side surface 121A. It may be. Needless to say, the shape and function of the glass run engagement protrusion 121e of the second embodiment shown in FIGS. 10A, 10B, and 10C are the same as the guide groove 21f of the first embodiment. It can also be applied to.

  Here, a method of forming the glass run engagement protrusion 121e will be described.

  As shown in FIG. 11A, a resin molding die 171 for molding the frame body 121 includes an upper die 171a, a lower die 171b, a main punching die 171c for molding a glass run engaging protrusion 121e, and a two-part split. The auxiliary punching die 171d.

  As shown in FIG. 11 (a), the main punching die 171c has a double taper on the side of the glass run engaging protrusion 121e, and two subtaps with one taper in the space formed by the upper and lower dies 171a and 171b. The die 171d is disposed so as to be engaged.

  As shown in FIGS. 11B and 11C, after the molding, the frame body 121 is taken out from the upper and lower molds 171a and 171b, the main punching mold 171c is pulled out on the side opposite to the glass run engaging protrusion 121e, and the taper is tapered. As a result, the auxiliary punching die 171d separated from the side surface of the guide groove 121f is pulled out from the guide groove 121f.

  By using the two types of punching die as described above, a part having an overhang in the punching direction can be easily molded.

  FIG. 12 shows a molding die and a molding procedure when the glass run engagement protrusion 121e is not provided on the lower side surface of the guide groove 121f. 11 is the same as the molding die and the molding procedure shown in FIG. 11 except that the main punching die 172c is a single taper and there is one sub punching die 172d.

  In the molding die 173 of FIG. 13, the main punching die 173c and the secondary punching die 173d are not tapered, and the secondary punching die 173d is divided into two near the middle of the guide groove 121f in the guide length direction. After completion of molding, the sub-cutting die 173d is pulled out in the guide length direction. This is a molding die used when the frame body 121 is curved as shown in FIG. 13 and it is difficult to form a taper between the main punching die 173c and the sub punching die 173d.

  The molding die 174 shown in FIG. 14 is used when the glass run engagement protrusion 121e is not formed near the center of the guide length of the guide groove 121f, and is formed in the guide groove 121f at the center of the main punching die 174c. 13 is the same as the molding die 173 shown in FIG. 13 except that it has a protrusion 174e that engages with the two auxiliary punching dies 174d. In this way, by providing the glass run engagement protrusion 121e only at both end portions 121B of the guide length of the guide groove 121f, the guide of the auxiliary punching die 174d is compared with the auxiliary punching die 173d of the molding die 173 shown in FIG. The length in the long direction can be shortened, and the moldability can be improved.

  As further shown in FIG. 8, in order to fix and attach the quarter window 120 to the rear door 110, there are two attachment portions 128, 129 at the upper and lower end portions of the rear frame portion 121b, and the front frame portion 121a. One attachment portion 127 is provided at the lower end portion.

  Further, as shown in the sectional view of the attachment portion 129 in FIG. 9, a nut 141 is embedded in the attachment portion 129 and molded. Although not shown, the mounting portions 127 and 128 have a structure in which a nut 141 is embedded, similarly to the mounting portion 129.

  As shown in FIGS. 7, 8, and 9, the rear frame part 121 b includes a holding part 121 d that extends along the length direction of the rear frame part 121 b. The holding part 121d is integrally formed in a shape that protrudes on the surface of the rear frame part 121b that faces the vehicle compartment direction.

  Next, attachment of the rear door 110 of the quarter window 120 will be described in detail.

  In a state where the quarter window 120 is attached to the rear door 110, the rear frame portion 121 b is disposed on the outer side in the vehicle width direction with respect to the frame portion 112. Then, the screw means 161 is fastened to the nut 141 of the attachment portion 129 through the through hole 112 c provided in the seat surface portion 112 b on the frame portion 112, and the rear frame portion 121 b is fixed to the frame portion 112. Similarly, in the attachment portion 128, the rear frame portion 121 b is fixed to the frame portion 112 by the screw means 161. Further, in the attachment portion 127, the lower end portion of the front frame portion 121 a is fixed to the door main body portion 111 by the screw means 161.

  With the quarter window 120 attached to the rear door 110, the holding portion 121d is positioned close to the vehicle rear side of the frame portion 112. Then, the quarter window panel 122 and the rear frame portion 121b are located outside the frame portion 112 in the vehicle width direction. That is, the door frame part 112 and the quarter window 120 overlap in the vehicle width direction. The frame part 112 is provided with a locking part 112 a extending along the length direction of the frame part 112. The holding part 121d and the locking part 112a are arranged so as to face each other, and are arranged to extend in parallel to each other.

  The weather strip 116 is attached by being held by the holding portion 121d and the locking portion 112a. That is, the mounting portion 116a provided in the weather strip 116 is supported on the seat surface portion 112b of the door frame portion 112, and is sandwiched between the holding portion 121d and the locking portion 112a and attached to the rear door 110. . When the rear door 110 is closed, the weather strip 116 is compressed between the rear door 110 and the vehicle body 117 to ensure watertightness between them.

  As described above, the quarter window 120 attached to the configured rear door 110 has the following advantages.

  The quarter window panel 122 and the rear frame portion 121b are positioned outside the frame portion 112 in the vehicle width direction, and the frame portion 112 does not form a design surface, so the rear frame portion is positioned outside the rear door 110 in the vehicle width direction. There is no joint between 121b and the frame part 112, and it is not necessary to fill this joint with a sealing material. Further, a joint portion between the rear frame portion 121b and the frame portion 112 (a through hole 112c provided in the seat surface portion 112b and a screw means 161 attached through the through hole 112c) is located inside the rear door 110 in the vehicle width direction. In fact, the water tightness of the joint portion is ensured by being covered by the attachment portion 116a of the weather strip 116 held between the rear frame portion 121b and the frame portion 112. For this reason, when the quarter window 120 is assembled to the rear door 10, it is not necessary to fill the joint between the rear frame portion 121b and the frame portion 112 with a sealant, and the assembly process can be reduced. Moreover, the concern about the sticking out of the sealing agent to the door surface is also eliminated.

  In the cross-sectional shape of the frame portion 112, a predetermined width dimension necessary for mounting the weather strip 116 in the vehicle width direction is secured. Since the screw means 161 is disposed so as to overlap the mounting portion 116a of the weather strip 116 in the vehicle width direction, it is not necessary to increase the cross-sectional shape as compared with, for example, a frame portion of a vehicle having no quarter window.

  Furthermore, the frame portion is generally manufactured at a low cost by a roll forming method in which a steel plate is bent. In order to sandwich and hold the weather strip 116, the frame portion 112 has only one locking portion 112a. For this reason, it can be set as the simplified cross-sectional shape with few bending, and reduction of a shaping | molding cost is achieved.

  As described above, the rear frame portion 121b is disposed on the outer side in the vehicle width direction with respect to the frame portion 112. If the width of the frame portion 112 is set to be equal to or narrower than the rear frame portion 121b in the vehicle front-rear direction, the frame portion 112 can be hidden behind the rear frame portion 121b in a side view of the vehicle. And the division | segmentation window part 120a can be set to a large area.

  In addition, because the front frame portion 121a and the rear frame portion 121b are covered with the quarter window panel 122 and are not exposed on the surface in the appearance of the vehicle, the door glass 115, the quarter window panel 122, and the rear of the quarter window 120 are also provided. In a vehicle that employs the gloss panel 117a in the vehicle body 117, it is possible to realize an external appearance that is integrated so that surface gloss is continuous over a large area.

  In the present embodiment, the quarter window 20 (120) is disposed on the rear door 10 (110) located on the rear side of the vehicle 1 (101), and is located behind the door glass 15 (115). It attached so that the area of the rear part of the part 10a (110a) might be divided and occupied. However, for example, the quarter window 20 (120) is disposed on the front door located on the front side of the vehicle 1 (101), and is located in front of the door glass so as to divide and occupy the area of the front portion of the window portion. It may be modified to be attached to. In this case, the relationship between the one end and the other end is reversed.
