Description

  The present invention relates to a protection sheet for a vehicle body that is used when assembling a vehicle such as an automobile and protects the front portion of the vehicle body.

  When assembling a vehicle such as an automobile, there is a possibility that, for example, a tool or the like may come into contact with and scratch the surface of the vehicle body. For this reason, the surface of the vehicle body is covered with a protective sheet as necessary to protect the surface of the vehicle body from scratches. Since the protective sheet is used at the time of assembling the vehicle, it is preferable that the protective sheet is as easy to attach and detach as possible.

  There are various methods of fixing to the protective sheet. For example, there is one in which the protective sheet is fixed to the surface of the vehicle body by a magnet on the surface of a metal door panel or the like. Further, for example, there is a type in which a hook is protruded from the upper edge of the protective sheet, and the protective sheet is fixed to the vehicle body by this hook (for example, see Patent Document 1).

Japanese Patent No. 2798376

  The surface of the vehicle body can also be protected by the protective sheet as described above. However, it is desired to develop a protective sheet that can be easily attached and detached and can reliably protect the surface of the vehicle body.

  If the protective sheet can be fixed to the vehicle body by the magnet as described above, the protective sheet can be attached and detached very easily, and the surface of the vehicle body can be well protected by the protective sheet. However, a non-magnetic material such as a resin material is also used as the material of the vehicle body, and there is a portion where the protective sheet cannot be fixed by a magnet. For example, the headlamp provided in the front part of the vehicle body has been increasing in size in recent years, and the need to protect the surface of the headlamp with a protective sheet is increasing. However, the cover of the headlamp is generally formed of a resin material, and the protective sheet cannot be fixed to the cover itself with a magnet.

  On the other hand, it is conceivable to protect the surface of the headlamp by fixing the protective sheet with the hook protruding as described above to the vehicle body. However, if the hook is simply hooked on the vehicle body, the protective sheet may come off due to vibration during transportation of the vehicle body. Further, for example, the surface of the headlamp can be protected by attaching a protective sheet with an adhesive tape or the like. However, such a protective sheet may increase the cost and may complicate the attaching / detaching operation.

  The present invention has been made in view of such circumstances, and provides a vehicle body protection sheet that can be easily attached to and detached from the vehicle body front portion and can well protect the vehicle body. Objective.

  A first aspect of the present invention that solves the above problem is a protective sheet for a vehicle body that is attached to a vehicle body body to protect the front part of the vehicle body when the vehicle is assembled, and is protruded from the vehicle body body corresponding to a hood. The protective seat for a vehicle body is provided with an engagement hole that engages with the hood damper, and the engagement hole is formed in a long hole shape whose short diameter is shorter than the diameter of the hood damper.

  In such a first aspect, the vehicle body protection sheet can be attached to the vehicle body very easily by fitting the hood damper into the engagement hole. In addition, since the engagement hole has a long hole shape, the protection sheet for the vehicle body can be attached to and detached from the vehicle body very easily. Further, since the short diameter of the engagement hole is shorter than the diameter of the hood damper, the hood damper is sandwiched between the vehicle body protection sheets, and the vehicle body protection sheet can be prevented from falling off due to vibration during transportation of the vehicle body.

  According to a second aspect of the present invention, there is provided the protection sheet for a vehicle body according to the first aspect, wherein a plurality of the engagement holes are arranged along the major axis direction.

  In the second aspect, the vehicle body protection sheet can be easily attached to the vehicle body. Moreover, since the major axis of each engagement hole is kept relatively short, the drop-off of the vehicle body protection sheet due to vibration is also suppressed. Further, even if the fixing position of the hood damper is slightly different, the vehicle body protection sheet can be attached to the vehicle body. In other words, the same body protection sheet can be applied to a plurality of vehicle types.

  According to a third aspect of the present invention, there is provided the protective sheet for a vehicle body according to the first or second aspect, characterized in that a core material made of a plastically deformable material is provided therein and is configured to be deformable. .

  In the third aspect, the shape of the vehicle body protection sheet can be changed in accordance with the shape of the vehicle body. Therefore, the vehicle body protection sheet can be brought into close contact with the vehicle body, and the surface of the vehicle body can be more reliably protected. In addition, the same body protection sheet can be applied to a plurality of vehicle types.

  According to a fourth aspect of the present invention, there is provided the vehicle body protection sheet according to any one of the first to third aspects, wherein at least a surface of a headlamp attached to the vehicle body is protected.

  In the fourth aspect, the surface of the headlamp made of a resin material can be reliably protected by the vehicle body protection sheet.

  According to such a protection sheet for a vehicle body of the present invention, it can be attached to and detached from the vehicle body very easily, and drop-off due to vibration during transportation of the vehicle body can be suppressed. Therefore, by employing such a vehicle body protection sheet, it is possible to reliably suppress damage to the vehicle body at the time of assembling the vehicle at a low cost.

FIG. 2 is a cross-sectional view of a vehicle body protective sheet according to an embodiment. 3 is a plan view illustrating an engagement hole of the vehicle body protection sheet according to the embodiment, and FIG. 3A is a diagram illustrating a state before the hood damper is engaged. (B) is a figure which shows the state after the hood damper was mounted | worn.

  As shown in FIG. 1, the protection sheet 10 for a vehicle body according to the present invention is attached to the front portion of the vehicle body when the vehicle 50 is assembled, and protects the front portion of the vehicle body from being scratched. Before describing the vehicle body protection sheet 10 in detail, first, the structure of the vehicle body front portion of the vehicle 50 to which the vehicle body protection sheet 10 is mounted will be briefly described.

  An engine room 52 is formed in a vehicle body 51 that includes various frames constituting the vehicle 50, and a front hood 53 that opens and closes an opening of the engine room 52 is provided in the vehicle body 51. A headlamp 54 is disposed at the front end portion of the vehicle body 51, and a front bumper 55 extending in the vehicle width direction is disposed below the headlamp 54.

  By the way, when the front hood 53 is closed, a considerable impact is applied to the vehicle body 51. Therefore, a hood damper 56 is provided in the vicinity of each headlamp 54 at the front end portion of the vehicle body 51. These hood dampers 56 are formed of a relatively hard rubber material or the like, and are mounted on the vehicle body 51 so as to protrude toward the front hood 53. When the front hood 53 comes into contact with the hood damper 56, the impact on the vehicle body 51 when the front hood 53 is closed is greatly reduced.

  In the present embodiment, as shown in FIG. 1, the vehicle body protection sheet 10 is mounted so as to cover the surface of the headlamp 54 of the vehicle 50, thereby preventing damage to the cover surface of the headlamp 54. . As will be described in detail later, the vehicle body protection sheet 10 is attached to a hood damper 56 provided so as to protrude from the vehicle body 51.

  The vehicle body protection sheet 10 includes a protection portion 11 that covers the surface of the headlamp 54 and a support portion 12 that is provided continuously from the protection portion 11 along the vehicle body 51. The protection part 11 is formed along the surface shape of the headlamp 54. Further, the protection part 11 is formed to be substantially the same as or slightly larger than the headlamp 54. That is, the protection part 11 is formed in a size that can reliably cover the surface of the headlamp 54.

  Further, as shown in FIG. 2, the vehicle body protection sheet 10 has a first layer 13 made of a nonwoven fabric provided on the vehicle body body 51 side, a second layer 14 made of a resin material such as urethane, and waterproof. It is comprised with the 3rd layer 15 which consists of material, for example, a resin film. Since the vehicle body protection sheet 10 has such a three-layer structure, the vehicle body protection sheet 10 itself does not damage the surface of the headlamp 54 or the vehicle body 51, and the surface of the headlamp 54 is contaminated. Adhesion can also be suppressed.

  The support portion 12 is formed with an engagement hole 16 with which the hood damper 56 is engaged. That is, by engaging the hood damper 56 with the engagement hole 16, the vehicle body protection sheet 10 is mounted on the vehicle body 51 while covering the surface of the headlamp 54.

  Here, the engagement hole 16 has a long hole shape as shown in FIG. Therefore, the vehicle body protection sheet 10 can be attached to the vehicle body 51 relatively easily without positioning the hood damper 56 and the engagement hole 16 with high accuracy. For example, even if there is a slight variation in the attachment position of the hood damper 56 to each vehicle body 51, the variation is absorbed by the engagement hole 16 being a long hole. The mating hole 16 can be reliably engaged. Further, by providing the engagement hole 16 as a long hole, for example, the vehicle body protection sheet 10 can be shared with a plurality of vehicle types in which the attachment positions of the hood damper 56 are slightly different.

  Here, as shown in FIG. 3A, the short diameter D <b> 1 of the engagement hole 16 before the hood damper 56 is engaged is shorter than the diameter D <b> 2 of the hood damper 56. For this reason, when engaging the hood damper 56 with the engagement hole 16, it is necessary to slightly expand the engagement hole 16 in the minor axis direction. As a result, as shown in FIG. 3B, in a state where the hood damper 56 is engaged with the engagement hole 16, the hood damper 56 is sandwiched between the support portions 12 and receives a predetermined pressure.

  By engaging the hood damper 56 with the engagement hole 16 in this way, the vehicle body protection sheet 10 is attached to the vehicle body 51, so that the vehicle body protection sheet 10 can be attached to the vehicle body 51 very easily. Detachable. Further, for example, even when the vehicle body is subjected to vibration during transportation, the vehicle body protection sheet 10 can be prevented from falling off from the vehicle body 51.

  The length of the engagement hole 16 in the major axis direction is not particularly limited, but if it is too long, the pressure received by the hood damper 56 engaged with the engagement hole 16 from the support portion 12 becomes too weak. For this reason, the length of the engagement hole 16 in the major axis direction is preferably about three times the minor axis direction at the longest.

  Moreover, in this embodiment, although the one engaging hole 16 was provided in the support part 12, the engaging hole 16 may be provided with two or more. For example, as shown in FIG. 4, the support portion 12 may be provided with three engagement holes 16 arranged along the major axis direction. With such a configuration, the vehicle body protection sheet 10 can be more easily attached to the vehicle body 51. In addition, it becomes possible to share one vehicle body protection sheet 10 for a plurality of vehicle types in which the attachment positions of the hood damper 56 are different. Moreover, since the major axis of each engagement hole 16 is kept relatively short, the dropout of the vehicle body protection sheet due to vibration is also suppressed.

  Although the vehicle body protection sheet 10 according to this embodiment is formed in advance along the surface shape of the headlamp 54, the vehicle body protection sheet 10 may be configured to be deformable. For example, as shown in FIG. 5, a core material 20 made of a plastically deformable material, such as a metal material, may be provided inside the vehicle body protection sheet 10. In this example, a plurality of the core members 20 are provided in a lattice shape. Of course, the arrangement of the core members 20 may be determined as appropriate and is not particularly limited. In this configuration, the shape of the vehicle body protection sheet 10 can be matched to the shape of the headlamp 54 by deforming the vehicle body protection sheet 10 together with the core member 20. Therefore, even when the vehicle body protection sheet 10 is shared by a plurality of vehicle types, the surface of the headlamp 54 can be more reliably protected. Moreover, cost reduction can also be achieved by sharing the vehicle body protection sheet 10 for a plurality of vehicle types.

  As mentioned above, although one Embodiment of this invention was described, Of course, this invention is not limited to the above-mentioned embodiment. The present invention can be modified as appropriate without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the vehicle body protection sheet 10 that covers and protects the surface of the headlamp 54 is described as an example. However, the vehicle body protection sheet 10 according to the present invention protects the front portion of the vehicle body. I just need it. Therefore, for example, the protection sheet 10 for the vehicle body may cover and protect the front bumper 55, or may cover and protect the head lamp 54 and the front bumper 55 integrally.
