Description

  The present invention relates to a vehicle resin window disposed in a vehicle so as to be movable up and down, and a vehicle door using the same.

2. Description of the Related Art Conventionally, a vehicle window made of glass, resin, or the like disposed on a vehicle door or the like so as to be movable up and down is known.
Among these, as a resin window (hereinafter referred to as a resin window), a plate-like main body portion including a visible region and a portion having other functions are integrally molded by taking advantage of the resin moldability. There is.

  In addition, as a vehicle window lifting device, for example, as described in Patent Documents 1 and 2, it is known to provide a rack that is fixed to a window body and in which a tooth row is formed on one side edge. It has been. A gear meshing with the rack is connected to a drive shaft of a motor fixed to the door body, and the window body is raised and lowered by the rotation of the motor. The rack teeth are arranged in the thickness direction of the window body or on the side edges of the window body. Such a structure does not require a space for the swing arm to swing and the volume required in the door panel is small compared to a structure in which the motor moves up and down the window body via the swing arm. That's it.

Japanese Utility Model Publication No. 60-150291 JP 2002-120556 A

In the case of a resin window, the rack (driven gear) of Patent Document 1 can be integrally formed when the window body is formed. Therefore, considering that the drive gear meshing with the driven gear and the rotating means such as the motor driving the drive gear are arranged in the door center direction with relatively few design restrictions, for example, the structure as shown in FIG. Conceivable.
As shown in the figure, the resin window 9 is provided with a driven gear 94 on the inner side surface 922 of the protruding piece 92 opposite to the side edge of the main body 91. The driven gear 94 meshes with a drive gear 984 such as a drive gear that is driven by rotating means 983 such as a motor.

However, the resin window 9 having the above-described configuration has the following problems.
That is, as shown in FIG. 8A, when the resin window 9 is molded using the molding die 97, the portion that molds the periphery of the protruding piece portion 92 of the resin window 9 is, for example, the first molding die 971. Molding is performed using the second mold 972. The first mold 971 includes two divided molds 971a and 971b. The split mold 971a is connected to a pin 971c inserted through a guide hole 979 provided in the split mold b, and is provided to be separated from the 971b by relatively advancing the pin 971c. The split mold 971a is provided with a gear forming portion 970 for forming the driven gear 94. Then, a resin as a material for the resin window 9 is poured between the first mold 971 and the second mold 972 to mold the periphery of the projecting piece portion 92 of the resin window 9.

  Here, the driven gear 94 is formed on the inner side surface 922 of the projecting piece 92 that is a surface perpendicular to the first surface 911 of the main body 91. Therefore, after the resin window 9 is molded, the split mold 971a provided with the gear forming portion 970 is directly directed from the resin window 9 in the direction X (the teeth of the driven gear 94) perpendicular to the first surface 911 of the main body portion 91. It was difficult to release in a direction perpendicular to the direction of the mountain and valley. This is because a chipped tooth or the like of the driven gear 94 may occur at the time of mold release.

  Therefore, as shown in FIG. 8 (b), the split mold 971a is once in a direction Y parallel to the first surface 911 of the main body 91 (a direction parallel to the tooth valley of the driven gear 94). And then removed from the driven gear 94 and then released from the resin window 9. In this way, by removing the molding die (divided molding die 971a) forming the driven gear 94 in a direction parallel to the direction of teeth of the driven gear 94, chipping of the driven gear 94 is suppressed. Thus, the resin window 9 can be molded.

However, in order to perform the above-described operation, a plurality of molds are arranged on the first surface 911 of the main body 91 of the resin window 9. That is, as shown in FIG. 8A, a split mold 971a for forming the driven gear 94 and a split mold b adjacent to the split mold 971a are required. Therefore, as shown in FIG. 8B, on the first surface 911 of the main body portion 91 including the visible region, division marks are formed on the boundary (division position A) between the division mold 971a and the division mold 971b. End up.
Since this divisional mark cannot be placed at a position where it can be visually recognized, for example, it is necessary to extend the weather strip disposed on the door-side support portion or the door to hide the divisional mark. As a result, the visible range was narrowed.

  The present invention has been made in view of such a conventional problem, and it is possible to sufficiently ensure a visible region without excessively narrowing a visible region, and to reduce a design restriction and a vehicle resin window. The present invention intends to provide a vehicle door using the same.

The present invention relates to a resin window for a vehicle disposed in a vehicle so as to be movable up and down.
A plate-like main body, and at least one of the side edges of the main body, and a protruding piece that protrudes in the thickness direction from one surface of the main body and is integrally formed with the main body And
A gear forming surface in which a driven gear is provided in the vertical direction is formed on the inner side surface of the projecting piece portion opposite to the side edge side of the main body portion.
An angle α formed by the one surface of the main body and the gear forming surface is an obtuse angle (claim 1).

  In the resin window of the present invention, a gear forming surface provided with the driven gear is formed on the inner side surface of the protruding piece. The angle α formed by the one surface of the main body and the gear forming surface is an obtuse angle. Therefore, when molding the resin window, a molding die for forming the driven gear (hereinafter, appropriately referred to as a gear molding die) is parallel to the one surface of the main body from the driven gear. There is no need to remove it (hereinafter referred to as the surface direction as appropriate). That is, it can be extracted in a direction other than the surface direction of the main body.

  Conventionally, since the direction in which the gear mold is pulled out from the driven gear is the surface direction of the main body, there are a plurality of molds that form the one surface side of the main body (see FIG. 8 described above). reference). On the other hand, in the present invention, the plurality of molds are integrated into an integral mold, and the integral mold can be removed from the driven gear and simultaneously released from the resin window ( (See FIG. 4 in the embodiment described later). Therefore, it is possible to eliminate the division marks on molding that have conventionally occurred by using a plurality of molding dies, and it is possible to mold the resin window with a sufficiently visible region. Further, the molding process can be facilitated by integrating the molding die.

  In addition, even if it is difficult to use the above-described integral mold due to the structure of the resin window or the driven gear, the integral mold is, for example, the one surface of the main body portion and the protruding piece portion. If the structure is divided at the boundary, the division position can be set at a place that does not affect the visible region of the resin window (see FIG. 6 in the embodiment described later). For this reason, it is possible to prevent formation of division marks in the visible region. Thereby, it can shape | mold in the state ensured enough, without narrowing the visible region of the said resin window too much.

  In the present invention, the gear forming surface is formed on the inner side surface of the protruding piece, and the driven gear is provided on the gear forming surface. Therefore, for example, when the resin window is attached to a vehicle door, a space for arranging a driving gear meshing with the driven gear and a rotating means for driving the driving gear is set in the center direction of the resin window, that is, the door. It can be sufficiently secured in the central direction. Therefore, design constraints can be reduced, and the degree of design freedom can be increased. This makes it possible to expand to various types of vehicles.

  Thus, according to the present invention, it is possible to provide a vehicle resin window that can be sufficiently secured without excessively narrowing the visible region and can reduce design restrictions.

2nd invention arrange | positions the resin window for vehicles of the said 1st invention so that raising / lowering is possible,
The vehicle door includes a drive gear meshing with the driven gear and a rotating means for driving the drive gear.

  The vehicle door of the present invention is configured such that the resin window can be moved up and down. The gear forming surface is formed on the inner side surface of the projecting piece in the resin window, and the driven gear is provided on the gear forming surface. Therefore, when the resin window is attached to the door, a space for arranging the driving gear meshing with the driven gear and the rotating means for driving the driving gear is set in the central direction of the resin window, that is, the door. It can be sufficiently secured in the central direction. Therefore, design restrictions on the door can be reduced, and design freedom can be increased. This makes it possible to expand to various types of vehicles.

3rd invention is the method of shape | molding the resin window for vehicles of the said 1st invention with a shaping | molding die, Comprising:
The molding die includes a first molding die corresponding to the surface shape on the one surface side of the main body portion in the resin window, and a second molding die corresponding to the surface shape on the other surface side of the main body portion. Become
The first mold is divided at a position corresponding to a boundary between the one surface of the main body and the projecting piece in the resin window. (Claim 3).

  In the method for molding a resin window for a vehicle according to the present invention, the first mold corresponding to the surface shape of the one surface side of the main body portion in the resin window is the one surface of the main body portion and the protruding piece portion. Is divided at a position corresponding to the boundary. That is, the dividing position of the first mold can be set at a place that does not affect the visible region of the resin window (FIG. 6 in the embodiment described later). For this reason, it is possible to prevent formation of division marks in the visible region. Thereby, it can shape | mold in the state ensured enough, without narrowing the visible region of the said resin window too much.

In the first to third aspects of the invention, when the resin window is molded, a mold (gear mold) for forming the driven gear is set in a direction parallel to the direction of the teeth of the driven gear ( Specifically, it is more preferable to pull out in the direction in which the tooth crest protrudes.
In this case, chipping of the driven gear at the time of molding can be suppressed, and the resin window can be molded with high accuracy.

A vehicle resin window according to an embodiment of the present invention will be described.
As shown in FIGS. 1 to 4, this example relates to a resin window 2 that is disposed so as to be movable up and down at a side door 8 for a vehicle. Note that the terms indicating the direction and position such as “front and rear”, “up and down”, “inside and outside” indicate the direction and position in a state where the resin window 2 is attached to the door 8.

In this example, as shown in FIGS. 1 to 4, the resin window 2 protrudes from the first surface 211 of the main body 21 in the thickness direction at the plate-like main body 21 and the front side edge 218 of the main body 21. The front projecting piece 22 is formed integrally with the main body 21.
A gear forming surface 222a in which the driven gear 24 is provided in the vertical direction is formed on the inner side surface 222 of the front projecting piece 22 opposite to the side edge of the main body 21. Further, the angle α formed by the first surface 211 of the main body 21 and the gear forming surface 222a is an obtuse angle.
This will be described in detail below.

  As shown in FIG. 1, the vehicle door 8 includes an inner panel (not shown) on the inner side of the vehicle and an outer panel 82 on the outer side of the vehicle. A window opening 821 that forms a visible region of the resin window 2 is provided above the outer panel 82. Further, a front guide frame 3 and a rear guide frame 4 are disposed in the vertical direction in front of and behind the window opening 821, respectively. The front guide frame 3 and the rear guide frame 4 are provided so as to extend below the lower end of the window opening 821. A resin window 2 is inserted between the front guide frame 3 and the rear guide frame 4.

  Further, as shown in the figure, a motor (rotating means) 83 and a drive gear (drive gear) 84 driven by the motor 83 are disposed in front of the inner panel, adjacent to the rear of the front guide frame 3. Has been. The front guide frame 3 is formed with a frame opening 30 on the inner panel side near the drive gear 84, and a part of the gear forming surface 222 a of the resin window 2 extends from the frame opening 30. Exposed.

As shown in FIG. 2, the resin window 2 protrudes from the first surface 211 of the main body 21 in the thickness direction at the plate-shaped main body 21 and the front side edge 218 and the rear side edge 219 of the main body 21. The front protrusion 22 and the rear protrusion 23 are configured. Here, the first surface 211 of the main body 21 is a surface on the vehicle inner side of the main body 21.
The resin window 2 is formed by integrally forming the main body portion 21, the front protruding piece portion 22, and the rear protruding piece portion 23, and has a substantially “U” shape in a horizontal cross section. The resin window 2 in this example is made of polycarbonate resin.

  As shown in FIGS. 1 and 2, the front projecting piece 22 and the rear projecting piece 23 in the resin window 2 slide in the front guide frame 3 and the rear guide frame 4 to form an engagement structure (not shown). Therefore, the movement of the front protrusion 22 and the rear protrusion 3 in the front-rear direction is restricted. In addition, the resin window 2 is more easily elastically deformed than glass because of its material. For this reason, the resin window 2 is prevented from being bent by the above structure.

As shown in FIGS. 2 and 3, a gear forming surface 222 a in which the driven gear 24 is provided in the vertical direction is formed on the inner side surface 222 of the front projecting piece 22. The driven gear 24 meshes with a drive gear 84 that is driven by a motor 83. Here, the inner side surface 222 of the front projecting piece portion 22 is an inner side surface opposite to the outer side surface 221 on the side edge side (front side edge side) of the main body portion 21 in the front projecting piece portion 22. .
Further, as shown in FIG. 2, the angle α formed by the first surface 211 of the main body 21 and the gear forming surface 222a is an obtuse angle.

  As shown in FIGS. 2 and 3, the inner side surface 222 of the front projecting piece 22 is formed with a connecting surface 222b that connects the first surface 211 of the main body 21 and the gear forming surface 222a. . By providing the connecting surface 222b, the wall portion 25 can be formed on one side surface of the driven gear 24. The wall 25 can increase the strength of the driven gear 24.

  As shown in FIGS. 1 and 2, the driven gear 24 formed on the gear forming surface 222 a of the front projecting piece portion 22 meshes with the drive gear 84 at the frame opening 30 of the front guide frame 3. The resin window 2 can be moved up and down along the front guide frame 3 and the rear guide frame 4 by driving the drive gear 84 with respect to the driven gear 24 of the front projecting piece 23 by the motor 83. It is configured.

Next, the molding of the resin window 2 of this example will be briefly described. In this example, the molding around the front protruding piece 22 that forms the driven gear 24 will be described.
First, as shown in FIG. 4A, a molding die 7 for molding the resin window 2 is set at a predetermined position. In the portion for molding the periphery of the front projecting piece portion 22 of the resin window 2, the first molding die 71 for molding mainly the first surface 211 side of the main body portion 21 and the second surface 212 side for molding the resin window 2. 2 molds 72 are set. The first mold 71 is provided with a gear forming portion 710 for forming the driven gear 24.

  Next, as shown in the figure, a molten polycarbonate resin that is a material of the resin window 2 is poured into the mold 7 to mold the resin window 2. As a result, the main body 21 and the front projecting piece 22 are formed between the first mold 71 and the second mold 72. The driven gear 24 is formed on the gear forming surface 222 a of the inner side surface 222 of the front projecting piece 22 by the gear forming portion 710 of the first mold 71.

Next, as shown in FIG. 4B, the mold 7 is released from the resin window 2. Here, in this example, the first molding die 71 is moved in the direction X perpendicular to the first surface 211 of the main body portion 21 of the resin window 2, and the gear molding portion 710 is removed from the driven gear 24 at the same time. The entire mold 71 is released directly from the resin window 2. Thereafter, the second mold 72 is released from the resin window 2.
Thus, the resin window 2 is molded.

Next, the effect in the resin window 2 of this example is demonstrated.
In the resin window 2 of this example, as shown in FIGS. 2 and 3, a gear forming surface 222 a provided with the driven gear 24 is formed on the inner side surface 222 of the projecting piece 22. And the angle (alpha) which the 1st surface 211 of the main-body part 21 and the gear formation surface 222a comprise is an obtuse angle. Therefore, as shown in FIG. 4, when molding the resin window 2, a molding die for forming the driven gear 24 (in this example, the first molding die 71) is moved from the driven gear 24 to the first surface of the main body 21. There is no need to pull in a direction Y (plane direction) parallel to 211. That is, in this example, the main body 21 is extracted in the direction X perpendicular to the first surface 211 and can be extracted in a direction other than the surface direction Y.

  As a result, conventionally, as shown in FIG. 8B described above, the direction in which the split mold 971a forming the driven gear 94 is removed from the driven gear 24 is the surface direction Y of the main body 921. There were a plurality of molds for forming the first surface 911 side of 91. On the other hand, in this example, as shown in FIG. 4, the first molding die 71 is formed by integrating the molding die that forms the first surface 211 side of the main body portion 21. As a result, the entire first mold 71 can be released directly from the resin window 2. Therefore, the division | segmentation trace on shaping | molding conventionally produced by using a some shaping | molding die can be eliminated, and it can shape | mold in the state which ensured the visible region of the resin window 2 enough. Further, the molding process can be facilitated by integrating the molds.

  Further, in this example, a gear forming surface 222 a is formed on the inner side surface 222 of the front projecting piece 22, and a driven gear 24 is provided on the gear forming surface 222 a. Therefore, when the resin window 2 is attached to the vehicle door 8, a space for arranging the drive gear 84 that meshes with the driven gear 24 and the motor 83 that drives the drive gear 84 is arranged in the center direction of the resin window 2, that is, It can be sufficiently secured in the central direction of the door 8. Therefore, design constraints can be reduced, and the degree of design freedom can be increased. This makes it possible to expand to various types of vehicles.

  Thus, according to this example, it is possible to provide a vehicle resin window 2 that can sufficiently secure a visible region and reduce design restrictions.

  Moreover, in this example, as shown in FIG. 4, the integrated 1st shaping | molding die 71 was used as a shaping | molding die which forms the 1st surface 211 side of the main-body part 21 of the resin window 2. As shown in FIG. However, for example, as shown in FIG. 5, in the case where the resin window 2 is curved in the vertical direction, it is separated directly from the resin window 2 using the integrated first mold 71 shown in FIG. It may be difficult to mold the structure.

Therefore, in such a case, as shown in FIG. 6A, the first mold 71 is positioned at the position corresponding to the boundary between the first surface 211 of the main body 21 and the front protruding piece 22 in the resin window 2. What is necessary is just to comprise by the division | segmentation shaping | molding die 71a, 71b divided | segmented by (4).
When the mold 7 is released from the resin window 2 after the resin window 2 is molded, the split mold 71a is divided into the split mold 71a and the split mold 71b as shown in FIG. 6B. It is moved in a direction parallel to the direction, and the gear forming portion 710 is removed from the driven gear 24, and at the same time, the split forming die 71a is released directly from the resin window 2. Further, as shown in FIG. 6 (c), the split mold 71 b is moved in the direction X perpendicular to the first surface 211 of the main body 21 of the resin window 2, and the split mold 71 b is separated directly from the resin window 2. Mold. Thereafter, the second mold 72 is released from the resin window 2.
Thus, the resin window 2 is molded.

Thereby, the division | segmentation position A of the division molds 71a and 71b can be set to a place that does not affect the visible region of the resin window 2. In addition, it is possible to prevent the formation of division marks in the visible region. Therefore, it can shape | mold in the state ensured enough, without narrowing the visible region of the resin window 2 too much.
It is of course effective to apply the mold having the structure shown in FIG. 6 to a case where the resin window 2 is linear (see FIG. 3) without being bent in the vertical direction.
