Description

  The present invention relates to a seal structure of a penetrating part that seals a penetrating part such as a striker, a latch, and a shaft that penetrates the vehicle body panel so as to face the vehicle interior side from the inside of the vehicle body panel. The present invention relates to a seal structure.

  Usually, in a vehicle, a striker, a latch, a shaft, etc. are mentioned as a penetration component which penetrates so that it may face a vehicle interior side from the inside of a body panel. The conventional configuration of the striker and latch will be described below. In FIG. 9, as an example of the configuration of the lock mechanism portion of the trunk lid 1 that opens and closes the trunk room of the vehicle, the trunk lid 1 is provided with a latch 2 so that the trunk lid 1 can be locked in a closed state. A striker 3 is provided on the trunk floor side so as to engage with the latch 2 in a state where the trunk lid 1 is closed.

  And this striker 3 is a penetration part which penetrates a vehicle body panel so that it may face a trunk room side from a vehicle body panel. As shown in FIG. 10, as a seal structure around the striker 3, a vehicle body is used to penetrate the striker 3. An opening 4a is formed in the trunk rear plate 4 as an interior part attached to the interior side of the panel (trunk floor panel) to allow the striker 3 to pass therethrough. A soft sheet 5 is disposed in the opening 4 a, and the soft sheet 5 is fixed to an escutcheon 6 that covers the periphery of the opening 4 a of the trunk rear plate 4. The escutcheon 6 is attached to a predetermined portion of the surface of the trunk rear plate 4 by engaging the locking claws 6 a with the edge of the opening 4 a of the trunk rear plate 4.

  As described above, as the sealing structure of the penetrating parts such as the conventional striker 3, the soft seat 5 is attached to the escutcheon 6 that borders the opening 4a of the trunk rear plate 4, and this soft seat 5 mounting structure is adopted. In this case, a lot of mounting fixtures such as washer 8 and push-on-fix 9 are required, and the mounting work requires two steps, a setting step and a welding step of the soft sheet 5, which increases the number of fixtures and the number of mounting steps. Therefore, there is a problem of incurring a cost increase. In addition, when the welding fixing structure is adopted, the problem that the soft sheet 5 is likely to be deformed or damaged easily occurs. When the structure in which the push-on fix 9 is inserted is adopted, the soft sheet 5 or the escutcheon 6 is deformed by the mounting pressure. It has been pointed out that there is a malfunction. Further, the escutcheon 6 requires a locking claw 6a for engaging with an interior part and a mounting boss 7 for attaching the flexible sheet 5, and there is a problem that the cost of a mold for manufacturing the escutcheon 6 increases. It is pointed out at the same time.

  The present invention has been made in view of such circumstances, and has a seal structure for penetrating parts such as strikers, latches, shafts, etc., which can save the number of mounting fixtures and shorten the mounting man-hours such as soft sheets and escutcheons. It is another object of the present invention to provide a seal structure for a penetrating part that can be easily and inexpensively performed without causing problems such as deformation and breakage during mounting.

  In order to solve the above-described problems, the present invention provides a seal structure for penetrating parts such as a striker, a latch, and a shaft that penetrates a hole in a vehicle body panel so as to face the vehicle interior side from within the vehicle body panel. An opening for penetrating the penetrating part is opened in the interior part attached so as to cover the indoor surface side, and a soft sheet provided with a slit-like through hole for penetrating the penetrating part is disposed so as to close the opening, Furthermore, in the sealing structure of the penetrating part in which a frame-like escutcheon is attached along the peripheral edge of the opening of the interior part, a latching claw is formed on the back surface of the escutcheon, and the latching claw is formed on the soft sheet. The soft sheet is supported and fixed to the escutcheon by being engaged with the mounting hole.

  Here, the penetration part is not particularly limited as long as it is a part that penetrates the vehicle body panel such as a striker, a latch, a shaft, or the like so as to face the vehicle interior side from within the vehicle body panel. Furthermore, the soft sheet is a rubber sheet or a soft resin sheet, and has a flexibility and a slit-like through hole for penetrating the penetrating part. The sealing action of the slit-like through hole This improves the sealing performance of the penetrating parts. Further, the escutcheon is made of a synthetic resin injection-molded body, and is set in a frame shape that borders the peripheral edge of the opening formed in the interior part.

  Therefore, according to the present invention, it is possible to support and fix the soft sheet at a predetermined position on the back surface of the escutcheon by engaging the engaging claw protrudingly formed on the back surface of the escutcheon with the mounting hole of the soft sheet. Mounting equipment such as washers and push-on-fixes is not required, and the number of mounting steps is one step.

  Next, in a preferred embodiment of the present invention, a hard resin plate is disposed on the back surface of the soft sheet, and the resin plate is attached with substantially the same shape at the same position as the mounting hole of the soft sheet. A hole is established, and the engagement strength of the engagement claw is enhanced by engaging the engagement claw of the escutcheon with both the attachment hole of the soft sheet and the attachment hole of the resin plate.

  Here, as the material of the resin plate, a hard resin material is preferable, the outer shape is almost the same as that of the soft sheet, and the opening that is substantially the same as the opening of the interior part is formed. An attachment hole that matches the attachment hole of the soft sheet is provided so that the soft sheet and the resin plate can be simultaneously engaged. That is, the resin plate has a back hold function for holding the soft plate from the back side.

  According to this embodiment, the flexible soft sheet is supported from the back side by the hard resin plate, and in particular, the engagement strength by the locking claw is at the edge of the mounting hole of the resin plate. Since the locking claw is firmly engaged, a strong mounting strength can be obtained, and deformation of the soft sheet can be effectively suppressed by the resin plate located on the back side thereof.

  Furthermore, in a preferred embodiment of the present invention, the locking claw provided on the escutcheon is inserted into the attachment hole of the soft sheet and then engaged with the edge of the opening of the interior part, thereby It is characterized by being fixed together on both the soft sheet and the interior part.

  And according to this embodiment, since the latching claw protrudingly formed on the back surface of the escutcheon has the function of engaging and fixing the soft sheet together with the interior parts, Since it is only necessary to form a locking claw that is engaged with both the soft sheet and the interior part, the mold equipment can be simplified and the number of mounting steps can be halved.

  As described above, according to the seal structure of the penetrating component according to the present invention, the soft sheet having the slit-like through hole that seals the periphery of the penetrating component is supported and fixed by the locking claw of the escutcheon. Compared to conventional welding fixing and machine fixing by push-on-fix, the number of equipment can be reduced and the number of mounting steps can be completed in one step of the one-touch mounting.

  Furthermore, according to the seal structure of the penetrating part according to the present invention, an escutcheon locking claw is used, and since an integral fixing method in which the soft sheet and the interior part are used together and fixed is adopted, the structure of the escutcheon, The shape can be further simplified, the number of mounting steps can be halved, and the cost can be greatly reduced.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a penetration part sealing structure according to the present invention will be described below in detail with reference to the accompanying drawings. It should be noted that the gist of the present invention is as described in the scope of claims, and the embodiments described below are merely examples of the present invention.

  1 to 4 show a first embodiment of the present invention. A seal for a striker (a member of a trunk lid locking mechanism) penetrating a vehicle body panel so as to face the indoor side from a hole of the vehicle body panel. FIG. 1 is an exploded perspective view showing the configuration of the seal structure of the striker, FIG. 2 is a cross-sectional view showing the seal structure, and FIG. FIG. 4 is a cross-sectional view showing a modification of the first embodiment.

  FIG. 1 shows a seal structure of a striker 12 that is connected to a mechanism portion (not shown) inside the vehicle body panel 10 and penetrates the vehicle body panel 10 through the hole 11 so as to face the vehicle interior side. Here, an interior part (trunk rear plate) 20 is mounted on the interior surface side of the vehicle body panel 10, and the interior part 20 has a rectangular opening 21 for allowing the striker 12 to face the interior of the vehicle interior. Has been established.

  Further, an escutcheon 30 that borders the peripheral edge of the opening 21 is attached to the surface of the interior part 20. The interior part 20 and the escutcheon 30 are made of an injection-molded body of a thermoplastic resin such as a polyethylene resin, a polypropylene resin, a polyester resin, and an ABS resin. A rectangular opening 31 having substantially the same dimensions is formed, and locking claws 32 are formed on the back surfaces of both sides of the opening 31 so as to project symmetrically.

  In the present invention, a soft sheet 40 made of synthetic rubber is disposed on the inner surface of the escutcheon 30 as a member for sealing the periphery of the striker 12. As the material of the flexible sheet 40, an optimal material may be selected as appropriate from synthetic rubbers such as diene (butadiene-styrene, butadiene-acrylonitrile), olefin (ethylene-propylene, chlorosulfonated polyethylene), and fluorine-containing compound. . The soft sheet 40 penetrates the striker 12 to the indoor side and has a slit-like through hole 41 formed in a cross shape at the center so that the periphery of the striker 12 can be sealed. A mounting hole 42 that allows the locking claw 32 is formed in a rectangular shape. As shown in FIG. 3, the dimensional relationship between the locking claw 32 of the escutcheon 30 and the mounting hole 42 of the soft sheet 40 satisfies the relationship of A ≧ B with respect to the thickness A of the locking claw 32 and the width B of the mounting hole 42. If you do.

  Thus, in order to seal the periphery of the striker 12, the soft sheet 40 is disposed so as to cover the opening 21 of the interior component 20 that covers the vehicle body panel 10, and the escutcheon 30 is attached to the interior component 20 from the surface side. . At this time, as shown in FIG. 2, the locking claw 32 of the escutcheon 30 is inserted into the mounting hole 42 of the soft sheet 40, and the locking claw 32 is fixedly fixed to the edge of the opening 21 of the interior part 20. Thus, installation can be completed with one touch.

  Therefore, there is an advantage that mounting equipment such as a washer and push-on fix required conventionally can be eliminated, mounting equipment can be saved, and man-hours can be shortened. Further, in the first embodiment, the structure in which both the soft sheet 40 and the interior part 20 are fixedly fastened by the locking claws 32 of the escutcheon 30 is adopted. However, as shown in the modified example of FIG. The seat 40 is supported by the locking claws 32, and the trim engagement locking claws 33 that are engaged with the edges of the openings 21 of the interior part 20 are separately set on the outer side of the seat 40. A configuration in which the flexible sheet 40 and the interior part 20 are individually fixed to the escutcheon 30 using 32 and 33 may be employed.

  5 to 8 show a second embodiment of the present invention, which is similarly applied to the seal structure of the striker 12. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The second embodiment is characterized in that a hard resin plate 50 for supporting the soft sheet 40 from the back side is provided. That is, the resin plate 50 is located between the interior component 20 and the soft sheet 40, and is composed of an injection molded body made of a hard thermoplastic resin such as polypropylene resin or polyamide resin as a material. Yes. In the resin plate 50, an opening 51 having substantially the same outer shape as the opening 21 of the interior component 20 and the opening 31 of the escutcheon 30 is formed in the center, and substantially coincides with the mounting holes 42 of the soft sheet 40 on both sides thereof. A rectangular attachment hole 52 is opened at a position where the operation is performed. Accordingly, as shown in FIG. 6 in which the escutcheon 30, the soft sheet 40, and the resin plate 50 are assembled to the interior part 20, the locking claws 32 formed on the back surface of the escutcheon 30 are attached to the soft sheet 40. It is inserted into the hole 42 and the mounting hole 52 of the resin plate 50, and is fixed to the edge of the opening 21 of the interior part 20.

  Therefore, also in the second embodiment, the soft sheet 40 and the resin plate 50 can be sandwiched and fixed between the interior part 20 and the escutcheon 30 only by using a pair of locking claws 32 formed on the escutcheon 30. This is advantageous in terms of work man-hours because it requires only a small number of fixtures and is completed in only one assembly process. Further, as shown in FIG. 7, two types of locking claws 32 and 33 are arranged in parallel on the escutcheon 30, and the soft sheet 40 and the resin plate 50 are fixedly fixed from the locking claw 32 on one side, and the other side It is also possible to adopt a configuration in which the locking claw 33 is engaged with the edge of the opening 21 of the interior part 20.

  As described above, in the second embodiment, since the hard resin plate 50 is disposed on the back side of the soft sheet 40 and the soft sheet 40 is fully supported from the back side, the deformation of the soft sheet 40 is made as much as possible. The attachment strength by the engagement claw 32 can be prevented and the engagement claw 32 is received at the edge of the attachment hole 52 of the hard resin plate 50, so that the attachment strength can be maintained firmly.

  Next, FIG. 8 shows a modified example of the engaging structure of the locking claw 32. Regarding the locking claw 32 of the escutcheon 30 and the mounting hole 42 of the soft sheet 40, the thickness A and the mounting hole of the locking claw 32 are shown. The relation of the width dimension B of 42 is A ≧ B, and if the slit 43 indicated by the symbol C is provided, the workability at the time of attaching the locking claw 32 in the attachment hole 42 of the soft sheet 40 can be improved. . The slit 43 only needs to satisfy the condition of A ≦ C.

  The first embodiment and the second embodiment described above are applied to the seal structure of the striker 12 disposed in the lock mechanism portion of the trunk lid panel. However, the vehicle body panel 10 faces the vehicle interior side from the vehicle body panel 10. In addition to the striker 12, the seal structure of the penetrating part penetrating the through hole can be applied to all penetrating parts such as a latch and a shaft. In addition, the shape of the slit-shaped through hole 41 provided in the soft sheet 40 and the shape of the mounting hole 42 may be changed as appropriate. Further, in consideration of the material and thickness of the soft sheet 40, the hard resin plate 50 is used. Thus, a configuration in which the back side of the soft sheet 40 is supported in a back-hold shape may be added.
