Description

  The present invention relates to a vehicle door structure in which an acoustic speaker is assembled to an inner panel having a device assembly work port.

  Automobile (vehicle) doors (front doors, rear doors, etc.) usually have a window inside a door panel that is a combination of an inner panel and an outer panel for raising and lowering the door window and locking the door. An elevating mechanism and a door lock mechanism are assembled. For this reason, in the door panel, a work port (for device assembly) for assembling various devices such as a window lifting mechanism and a door lock mechanism is formed on the plate surface of the inner panel. At the same time, a waterproof sheet, most of which is a waterproof film, is used to waterproof the work opening so that water does not enter the door panel from the work opening. Yes.

  In many of these doors, in order to ensure good sound and sound quality, as shown in Patent Document 1, an acoustic speaker of an acoustic device is attached to an inner panel of a door panel.

  By the way, in automobiles equipped with an audio device, there is a demand for reproducing clear sound. For this reason, recently, high quality of sound and sound quality is being demanded.

  However, the structure that waterproofs the inner panel with a water-proof film transmits sound from the back of the acoustic speaker through the inside of the door panel to the film part that closes the opening of the work opening, and the film part vibrates (resonates). May cause (buzzing sound). Moreover, there is a problem that sound from the front of the acoustic speaker is attenuated by sound from the back of the acoustic speaker, and sound quality and sound are impaired.

  In other words, as the sound and sound quality become higher, countermeasures against such vibration noise become important.

Therefore, in some cases, the waterproofing by the water-proof film is left as it is, and the work opening is closed with a rigid sheet metal lid or resin lid to prevent the water-proof film from resonating.

[One Embodiment]
Hereinafter, the present invention will be described based on an embodiment shown in FIGS.

  FIG. 1 is a perspective view showing an appearance of a vehicle door, for example, a rear slide door 1 of a passenger car, and FIG. 2 is an exploded perspective view of a part of the door 1.

  In FIG. 2, reference numeral 2 denotes a door body (made of metal) of the front door 1. The door body 2 includes a box-shaped door panel 5 formed by combining an outer panel 3 and an inner panel 4, and a frame-shaped sash 6 formed on the upper portion of the door panel 5. Among them, the front panel portion 5a facing the vehicle compartment side of the inner panel 4 is provided with a plurality of large and small square device assembly work ports 7 on the front and rear sides in the vehicle front-rear direction as shown in FIG. ing. For example, rectangular work ports 7a and 7b are provided in the upper and lower stages on the front side, and a larger square work port 7c is provided in the rear middle stage. Further, a speaker mounting hole 8 is provided in the front middle portion of the front panel portion 5 adjacent to the work openings 7a to 7c. Then, door built-in devices (not shown) such as a window lifting mechanism and a door lock mechanism are mounted inside the door panel 3 through the work ports 7a to 7c. Further, the speaker mounting hole 8 is mounted with an acoustic speaker 9 of an acoustic device (not shown) as shown in FIG.

  Among these device assembly work ports 7a to 7c, work ports that are easily affected by the acoustic speaker 9 and are required to be waterproof, for example, all the device assembly work ports 7a to 7c are for waterproofing and sound insulation. The lid body 12 with a seal is assembled. The same structure is used for all of the lids with seals 12. 3 to 5 show the structure of the lid 12 with a seal and the portion that receives the lid 12 with a seal as details of the structure.

  Describing the structure, the receiving structure uses a structure in which a belt-shaped seating surface 13 (for receiving a lid) is formed at the edge of the device assembly work port 7c. Specifically, as shown in FIGS. 4 and 5, the seat surface 13 has, for example, an annular band shape that is stepped at the edge of the device assembly work port 7c and is continuous in the circumferential direction of the work port 7c. The structure which forms the same plane is used.

  Further, as shown in FIG. 3, the lid with seal 12 has a structure having a cover portion 15 made of synthetic resin and an annular elongated butyl rubber material 16 as a seal member. Specifically, the cover portion 15 is plate-shaped and has a shape suitable for closing the opening of the device assembly work port 7c, specifically, a shape that covers up to the seating surface 13. That is, the shape of the cover portion 15 is a shape that closes the opening of the device assembly work port 7c while the edge portion overlaps with the seating surface 13 (the edge portion of the work port) when the cover portion 15 is accommodated in the step. In addition, the cover part 15 is formed with a bead part 17 for increasing the rigidity of the entire cover part, and ensures the rigidity and strength necessary for sound insulation. Of the inner surface of the cover portion 15, the butyl rubber material 16 is attached to the entire circumference of the edge overlapping the seat surface 13 (the edge of the work port), and the seat surface 13 (the device assembly work port 7 c). It is a structure that can be sealed between.

  Further, at the edge portion of the outer cover portion 15 sandwiching the butyl rubber material 16 disposed on the entire circumference, there are a plurality of small holes 19 necessary for screwing the cover portion 15 with a minimum number as a fixing portion. For example, it is provided at three predetermined locations. A screw hole 14 is provided in the seating surface 13 in accordance with the point of the small hole 19. At the edge portion of the cover portion 15 on the inner side of the butyl rubber material 16, a claw portion 20 is provided so as to be located between the small holes 19, specifically, approximately in the middle between the small holes 19. The claw portion 20 protrudes from the inner surface of the cover portion 15, and the shape of the claw 20 a at the tip portion is when the device assembly work port 7 c is closed with the cover portion 15 while pressing the butyl rubber material 16 against the seat surface 13. It has a shape that engages and disengages with the end of the seating surface 23 (the opening end of the device assembly work hole 7c). That is, it is performed by screwing performed by screwing the screw member 21 into the screw hole 14 from the small hole 19 and by engaging the claw portion 20 with the end of the seat surface 23 (the opening end of the device assembly work hole 7c). Therefore, the lid 12 with the seal is fixed while the butyl rubber material 16 is pressed against the seating surface 13. Further, utilizing the fact that the small holes 19 and the claw portions 20 are arranged in a staggered manner on both sides of the butyl rubber material 16, the entire periphery of the cover portion 15 is connected to the device assembly work port 7 c with a uniform fastening force. The structure can be fastened (fixed). In addition, the dashed-two dotted line in FIG. 3 has shown the area | region of the opening of the work opening 7c for apparatus assembly.

  As shown in FIG. 2 and FIG. 3, first, the cover 15 is fitted into the step of the peripheral edge in accordance with the shape of the device assembly work port 7 c as shown in FIGS. 2 and 3. . Then, the claw portions 20 are engaged with the ends of the seat surface 20 while the cover portion 15 is pressed and the butyl rubber material 16 is deformed between the seat surface 20. Then, the lid 12 with the seal is supported in a state in which the device assembling work port 7c is closed by the cooperation of the sticking force of the butyl rubber material 16 sticking to the seat surface 13 and the engaging force of the claw portion 20 ( Temporary fixing). Thereafter, when the screw member 21 is screwed through the small holes 19 that coincide with the screw holes 14, the cover portion 15 closing the device assembly work port 7c is fixed to the front panel portion 5a. As a result, the device assembly work port 7 c is closed by the lid 12 while being sealed with the work port 7 c by the butyl rubber material 16.

  The openings of the other device work ports 7a and 7b are also closed by the sealed lid body 12 in the same manner.

  The device assembly work ports 7a to 7c thus blocked by the lid body 12 are all shielded by a rigid body called the lid body 12 and are also provided at the edges of the device assembly work ports 7a to 7c. The rigidity strength is increased. At the same time, the device assembly work ports 7a to 7c are waterproofed by the sealing function provided by the lid 12 itself.

  Therefore, the adoption of the lid body 12 with the seal ensures the sealing performance of the device assembly work ports 7a to 7c by the lid body 12 itself, which has conventionally been a cause of the generation of resonance noise (billing noise). The waterproof sheet that has been used for waterproofing is no longer necessary. Therefore, it is possible to prevent a reduction in assembling workability when assembling the rear slide door 1 (door) and to reduce a cost burden. At the same time, the sound speaker 9 is improved by the sound insulation provided by the rigidity of the lid 12 with the seal (due to the sealing performance of the high-rigidity cover 15 and the butyl rubber material 16) and the rigidity of the device assembly work ports 7a to 7c. It can cope with pressure from the back side (back pressure), sound leakage from the back side, etc., and can improve sound quality and sound (acoustic performance: high). Moreover, the lid 12 with the seal is easy to prepare in accordance with the shape of the device assembly work ports 7a to 7c, and has an advantage that it can be easily applied to many vehicle types.

  In particular, the main structure of the lid 12 with the seal is a structure in which the butyl rubber material 16 is provided on the inner surface of the cover portion 15 that prevents the opening of the device assembly work port 12, so that a simple structure is sufficient. In addition, the cover portion 15 can be deformed by having a plate shape, and is not in the same planar shape in which the edge of the device assembly work port 12 is easily closed, but has an uneven shape (a shape that cannot be followed by the butyl rubber material 16 alone). However, it can follow the changed shape (followability: good) and can be easily used for the device assembly work port 12 of any vehicle type.

  In addition, since the structure with the screwed structure (fixed by the screw member 21) and the locking structure (fixed by the claw portion 20) is used as the fixing of the sealed lid body 12, the sealed lid body 12 is It can fix firmly, reducing the part fixed with the troublesome screw member 21. FIG. In particular, this structure can greatly fix the assembly of the rear slide door 1 because the lid 12 can be stably fixed while omitting troublesome screwing work.

    In addition, since the parts to be screwed and the parts to be locked are arranged in a staggered manner on both sides of the butyl rubber material 16, the butyl rubber material to which the fastening force by screwing and the fastening force by the claw portion 20 are attached. 16 has an advantage that the lid 12 can be fixed stably and effectively.
