Background
In motor vehicles, weight reduction of the vehicle body structure is required for improving fuel efficiency. As a method for this purpose, there are a method of reducing the plate thickness of a member, a method of thinning a part of a member, and the like. However, the above method should be used without reducing the strength of each component.
The same is true for doors for motor vehicles. In particular, a side door of an automobile requires not only basic strength but also strength capable of withstanding a load applied as a lift glass is lifted. Further, it is necessary to prevent the door member from being deformed by repeated lifting and lowering of the lifter glass, and the door inner panel or the door outer panel from being twisted due to long-term use, which affects the lifting and lowering of the lifter glass.
A glass run channel is provided at the edge of the lifting glass to suppress vibration of the lifting glass and prevent water and dust from entering the vehicle interior from the outside. In addition, for the glass run and the lift glass, a door sash is provided to support the glass run and guide the lifting movement of the lift glass.
A door sash is an important part in order to smoothly raise and lower a sash and to reduce the weight of a door while securing the strength required for the door, and thus the door sash plays an important role in a door structure for a vehicle.

Detailed Description
In a door sash structure according to an embodiment of the present invention, a door sash includes: one end formed with a glass run mounting portion; and the other end formed with a first fixing portion fixed to the door inner panel and a second fixing portion fixed to the door outer panel, the door sash being integrally formed of resin to improve rigidity of the door pillar.
[ embodiment ]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In fig. 1 to 4, a vehicle door 1 is shown. The door panel of the door 1 includes a door inner panel 2, a door outer panel 3, and a door reinforcement 4. The door inner panel 2 and the door outer panel 3 are joined at respective edge portions 2S and 3S.
As shown in fig. 1, 3 and 4, the pillar 5 of the door 1 is provided with: an interior trim 18 for covering the door inner panel 2; an exterior trim 19 for covering the door outer panel 3; and a door sash 7 disposed inside the door panel and configured to guide a lifting movement of the lift glass 6. The door sash 7 is made of resin.
[ Structure of door sash 7 ]
The door sash 7 is formed to be long in the vertical direction and to extend toward the lower portion of the pillar 5. The door sash 7 includes a glass run mounting portion 8, and the glass run mounting portion 8 has a vertical groove shape that opens toward the vehicle front side Fr. The glass run mounting portion 8 is fitted to a mounting base portion 9K of a glass run 9 (weather strip) made of a rubber-like elastic body. The glass run 9 has a seal portion 9A, and the seal portion 9A is pressed against both glass surfaces of the lift glass 6 to prevent rainwater and the like from entering the vehicle compartment.
As shown in fig. 1 and 5, the door sash 7 has an extension 10 formed at an upper portion thereof near the rear lower end portion of the opening 1H of the door 1, and the extension 10 is formed so as to extend toward the vehicle rear side Rr. Further, the protruding portion 10 is provided with a first fixing portion 11 fixed to the door inner panel 2 and a second fixing portion 12 fixed to the door outer panel 3. The extension 10 is located on the back side of the glass run mounting portion 8. In other words, the door sash 7 includes one end 7A formed with the glass run mounting portion 8 and the other end 7B formed with the first fixing portion 11 fixed to the door inner panel 2 and the second fixing portion 12 fixed to the door outer panel 3, and the door sash 7 is integrally molded from resin.
Therefore, the door inner panel 2, the door outer panel 3, and the glass run 9 (the sash glass 6) are integrated around the door sash 7. As a result, positional deviation between the individual components (i.e., the door sash 7, the door inner panel 2, the door outer panel 3, and the glass run 9) can be suppressed, and the rigidity of the door sash 7 and the pillar 5 of the door 1 can be improved.
As described above, the strength of the connection of the door sash 7 to the door inner panel 2 and the door outer panel 3 can be improved, and the rigidity of the door sash 7 and the pillar 5 of the door 1 can be improved.
Since the door inner panel 2 and the door outer panel 3 are integrated with the door sash 7 interposed between the door inner panel 2 and the door outer panel 3, the distance between the door inner panel 2 and the door outer panel 3 can be accurately set, and the sash 6 can be smoothly raised and lowered for a long period of time.
The door sash 7 is attached to a notch portion formed in the door panel. However, since the notched portion is likely to be formed with a gap, there is a possibility that water and dust intrude into the notched portion, and vibration and sound propagate through the notched portion. On the other hand, according to the structure of the embodiment of the present invention, the gap can be filled with the moldability of the resin, thereby suppressing it. In other words, by using the door sash 7 made of a resin having high moldability, it is possible to form a shape having high sealing properties between the door inner panel 2 and the door outer panel 3, and further, it is possible to suppress the entry of vibration, noise, and water.
[ Structure of the extension 10 ]
As shown in fig. 3 and 5, a portion 31 of the upper portion of the protruding portion 10 on the vehicle front side Fr is formed integrally with the annular wall portion 20 having a rectangular shape that opens toward the vehicle width direction outer side W2 (i.e., the vehicle cabin outer side) when viewed in side view, and the annular wall portion 20 having a rectangular shape that opens toward the vehicle width direction inner side W1 (i.e., the vehicle cabin inner side) when viewed in side view. A portion 32 of the upper portion of the protruding portion 10 on the vehicle rear side Rr is formed in a U shape that opens toward the vehicle rear side Rr when viewed in a sectional view (see fig. 3). The first fixing portion 11 is constituted by forming the bolt insertion hole 40 in the side wall 32S of the portion 32 on the vehicle rear side Rr that is on the vehicle width direction inner side W1. In this manner, the annular wall portion 20 is disposed between the glass run mounting portion 8 and the first fixing portion 11.
As shown in fig. 3, a side wall 32K (corresponding to a boundary portion between the door sash 7 and the outer panel 3) located on the vehicle width direction outer side W2 of the portion 32 located on the vehicle rear side Rr is configured by extending a tip end of the annular wall portion 20 toward the vehicle rear side Rr, and the side wall 32K faces the door outer panel 3. Therefore, the door sash 7 can be given resistance to surface contact with the door outer panel 3, and this resistance acts when the side wall 32K contacts the door outer panel 3. Further, even in the case where the cushioning material for cushioning the contact with the plate surface is provided, since the side wall 32K supports the cushioning material, the mounting state of the cushioning material is stable. In addition, the annular wall portion 20 that supports the glass run mounting portion 8 can be reinforced with the side wall 32K.
At the intermediate portion 33 and the lower portion 34 in the up-down direction of the protruding portion 10, the annular wall portion 20 having a rectangular shape that opens toward the vehicle width direction outer side W2 when viewed in side view is formed integrally with the annular wall portion 20 having a rectangular shape that opens toward the vehicle width direction inner side W1 when viewed in side view in a state of being aligned in the up-down direction and the vehicle front-rear direction (align). The second fixed portion 12 is configured by forming a bolt insertion hole 40 in a wall portion 37 of the protruding portion 10 located on the vehicle rear side Rr with respect to the annular wall portion 20. In other words, the plurality of annular wall portions 20 are arranged in the range in the vehicle front-rear direction from the glass run mounting portion 8 to the second fixing portion 12 and in the range in the up-down direction from the glass run mounting portion 8 to the second fixing portion 12. As a result, the intermediate walls between adjacent annular wall portions 20 increase, so that the strength and rigidity of the annular wall portions 20 can be improved to suppress collapse of the annular wall portions 20.
The plurality of annular wall portions 20 may be arranged in a range in the vehicle front-rear direction from the glass run mounting portion 8 to the first fixing portion 11 and/or may be arranged in a range in the up-down direction from the glass run mounting portion 8 to the first fixing portion 11.
The first fixing portion 11 is located rearward and upward of the second fixing portion 12 (upward of the vehicle rear side Rr), and is located on the vehicle width direction inner side W1 with respect to the second fixing portion 12. In fig. 6, a plurality of annular wall portions 20 (five annular wall portions in the present embodiment (the number of annular wall portions is not limited thereto)) each having a rectangular shape that opens toward the vehicle width direction inner side W1 are shown by thick lines.
As shown in fig. 5, the annular wall portion 20 has a front wall 21 and a rear wall 22 in the vehicle front-rear direction, and has an upper wall 23 and a lower wall 24 in the vehicle up-down direction. In other words, the back of the glass run mounting portion 8 is provided integrally with an annular wall portion 20 having a front wall 21, a rear wall 22, an upper wall 23, and a lower wall 24.
Therefore, the annular wall portion 20 extending between the door inner panel 2 and the door outer panel 3 exhibits resistance to the compressive force from the door inner panel 2 and the door outer panel 3, thereby suppressing deformation of the door sash 7. In addition, the closed cross section of the annular wall portion 20 is formed on the back side of the glass run 9, so that the fixation of the glass run 9 is stable. As a result, the vertically movable glass 6 can be smoothly moved up and down.
Specifically, a load applied to one panel surface of one of the door panels (the door inner panel 2 or the door inner panel 3) is received by the panel surface of the other of the door panels, and the annular wall portion 20 supports the door sash 7 between the door inner panel 2 and the door outer panel 3.
Therefore, deformation of the door panel can be suppressed, and the influence of the glass run 9 on the vertical movement of the vertically movable glass 6 can be reduced. In addition, the load acting on the lift glass 6 and the glass run 9 is received by the closed cross section of the annular wall portion 20 on the back side thereof, and is supported by the panel surfaces of the door inner panel 2 and the door outer panel 3 on the back side thereof. Therefore, deformation can be suppressed.
As shown in fig. 5, at the vehicle rear side Rr of the annular wall portion 20 that is formed at the intermediate portion 33 in the vertical direction of the protruding portion 10 and has a rectangular shape when viewed in side view, a second annular wall portion 25 is formed around the second fixing portion 12, and a third annular wall portion 26 is formed adjacently below the second annular wall portion. The rear wall 28 of the second annular wall portion 25 is formed in an arc shape that is convex toward the vehicle rear side Rr. The rear wall 29 and the lower wall 30 of the third annular wall 26 are formed in an arc shape projecting rearward and downward, and the rear wall 29 and the lower wall 30 are smoothly connected.
As shown in fig. 3, the covering portion 39 for covering the opening portion of the annular wall portion 20 that opens toward the vehicle transverse direction outer side W2 extends from the end portion of the door outer panel 3 located on the vehicle front side Fr toward the vehicle front side Fr. According to this structure, the opening necessary for forming the door sash 7 is closed by the covering portion 39, whereby a closed cross section is formed by the door sash 7 and the annular wall portion 20. Therefore, the door sash 7 can be further reinforced to suppress deformation of the opening.
[ fixing Structure Using the first fixing part 11 ]
As shown in fig. 3, the end portions of the door inner panel 2 and the door reinforcement 4 on the vehicle front side Fr overlap in the vehicle width direction. The nut 41 is fixed to the end portion of the door reinforcement 4 on the vehicle front side Fr from the vehicle width direction outer side W2 such that one end surface of the nut 41 is superimposed on the side wall 32S of the portion 32 of the extension portion 10 on the vehicle rear side Rr. Then, the bolt 50 is inserted into the bolt insertion hole formed in the end portions of the door inner panel 2 and the door reinforcement 4 on the vehicle front side Fr, and the bolt 50 is screwed into the nut 41. Further, the tip end portion of the bolt 50 protruding from the nut 41 is fitted into the bolt insertion hole 40 of the first fixing portion 11. The nut 41 is formed with an enlarged diameter portion 41A, and the enlarged diameter portion 41A abuts against the annular wall portion 20 from the vehicle rear side Rr.
[ fixing Structure Using the second fixing part 12 ]
As shown in fig. 4, the wall portion 37 of the extension portion 10 and the base portion 19D bulging from the inner surface of the exterior trim 19 sandwich the end portion of the door outer panel 3 on the vehicle front side Fr in the vehicle width direction. Then, the bolt 50 is inserted into the bolt insertion hole 40 formed in the wall portion 37 and the base portion 19D and the bolt 50 is screwed into the nut 41 disposed in the base portion 19D, whereby the wall portion 37 and the base portion 19D are clamped and fixed to the end portion of the door outer panel 3 on the vehicle front side Fr.
The lift glass 6 is typically formed in a pentagon shape; however, in recent years, the lift glass 6 may have a quadrangle shape. The embodiment of the present invention is particularly effective for the door 1 having the sash 6 of an approximately quadrangular shape because a load burden on the door sash 7 is large during the up-and-down movement of the sash 6 having a quadrangular shape.
[ other embodiments ]
