[0002] For example, Patent Document 1 discloses an easily peelable paint that is applied to the surface of a vehicle or the like. By using such an easily peelable paint, a peelable coating film can be formed on the surface of the vehicle, and this coating film can be peeled off and another coating film can be easily formed on the surface of the vehicle. Furthermore, when repairing the vehicle, the peelable coating film can be easily peeled off. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-100713 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, if a peelable coating film is formed using the technology of Patent Document 1, and if part of the coating film is scratched, the entire coating film, including the unscratched part of the coating film, will have to be peeled off from the entire surface of the coated exterior component. As a result, the coating film that did not need to be peeled off in the first place will have to be peeled off and the area will have to be repainted, which increases the repair work and repair costs.

[0005] The present invention has been made to solve such technical problems, and its object is to provide a vehicle structure in which a coating film applied to the exterior surface of an exterior member can be partially peeled off without peeling off the entire coating film. [Means for solving the problem]

[0006] In consideration of the above problems, the vehicle structure of the present invention is a vehicle structure comprising an exterior member of a vehicle and a peelable coating film formed by applying an easily peelable paint to an exterior surface of the exterior member, wherein a resin tape is provided on the exterior surface of the exterior member so as to partition a surface area of ​​the exterior surface, and the exterior surface of the exterior member is covered with the coating film together with the resin tape. Effect of the Invention

[0007] According to the present invention, the coating film is formed by applying an easily peelable paint to the exterior member of the vehicle, so that the adhesion between the coating film and the exterior member of the vehicle is easily maintained and the coating film can be easily peeled off from the exterior surface of the exterior member. Here, the exterior surface of the exterior member is covered with the coating film together with a resin tape, and the resin tape is provided so as to define the surface area of ​​the exterior surface. The resin tape allows the coating film covering the defined surface area to be partially peeled off starting from the resin tape. As a result, the coating film applied to the exterior surface of the exterior member can be partially peeled off without peeling off the entire coating film. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a vehicle structure according to the present invention will be described with reference to the drawings. The vehicle in this embodiment includes automobiles, trains, etc., but the following description will be given by taking an example of a passenger car among automobiles.

[0010] FIG. 1 is a perspective view showing a vehicle structure according to this embodiment. As shown in FIG. 1, a vehicle 1 is provided with an exterior member 6. Here, the exterior member 6 is made up of an exterior plate and an exterior part. The exterior plate constituting the exterior member 6 refers to an exterior panel that is a member constituting a vehicle body and is visible from the outside (in other words, visible from outside the vehicle). The exterior plates include, for example, a hood panel 60, a roof panel 61, a trunk lid 62, a front fender panel 63, a rear fender panel 64, a front door outer 65, a rear door outer 66, a front pillar 67, a center pillar 68, and a rear pillar 69. For example, a hot-rolled steel plate or a cold-rolled steel plate is used as the material of the exterior plate.

[0011] On the other hand, the exterior parts of the vehicle 1 refer to fitting parts that are attached to the vehicle body and can be seen from the outside, and include, for example, a front bumper cover 70, a rear bumper cover 71, a rocker panel molding 72, a door handle 73, a fuel filler cover 74, a side mirror 75, a roof molding 76, a door belt molding 77, a weather strip 78, a window molding 79, and a shark fin (not shown), etc. Resin materials are mainly used as materials for the exterior parts, but the fuel filler cover 74 is often made of steel plate.

[0012] Some or all of the exterior members 6 among the above-mentioned exterior panels and exterior parts are each formed with a peelable coating film 30. More specifically, the exterior surfaces, side end faces, and, if necessary, part of the back faces of these exterior panels and exterior parts are provided with a peelable coating film 30 formed by painting an easily peelable paint so as to cover these surfaces. By forming the coating film 30 by painting an easily peelable paint on the exterior panels and exterior parts of the vehicle 1 in this way, the adhesion between the coating film 30 and the exterior panels and exterior parts of the vehicle 1 can be easily maintained.

[0013] More specifically, as shown in Fig. 1, a resin tape 40 is provided on an exterior surface 6a (Figs. 2 to 5) of an exterior member 6 such as a hood panel 60, a roof panel 61, a front fender panel 63, a front door outer 65, and a rear door outer 66 so as to partition the surface area of ​​the exterior surface 6a. The exterior surface 6a of the exterior member 6 is covered with a coating film 30 together with the resin tape 40. Here, the exterior surface 6a is a design surface visible from the outside of the vehicle 1, and in this embodiment, at least the entire surface of the exterior surface 6a is covered with the coating film 30.

[0014] A clear layer may be further formed on the outside of the coating film 30. By forming the clear layer in this manner, the weather resistance and chemical resistance of the coating film 30 can be improved, and the gloss and luxurious feel can be further enhanced.

[0015] Here, when the exterior member 6 is an exterior plate, the exterior plate has a steel plate, an electrodeposition layer formed so as to cover the entire steel plate, and an intermediate coat layer, a base layer, and a clear coat layer formed in this order on the electrodeposition layer on the front side of the exterior plate, although not shown. In this case, the surface of the clear coat layer corresponds to the exterior surface 6a of the exterior member 6.

[0016] The coating film 30 is a resin coating film, and is a peelable coating film formed by applying an easily peelable paint to the exterior member 6. Since the coating film 30 is formed by applying an easily peelable paint as described above, it has the property of being peelable, as compared to a normal coating film consisting of an electrodeposition layer, an intermediate coat layer, a base layer, and a clear coat layer.

[0017] The material of the easily peelable paint is not particularly limited as long as it is a paint that can be easily peeled off from the fender panel 13. For example, an example of the easily peelable paint is a paint in which xylene, ethylbenzene, an antioxidant, methyl ethyl ketone, a silica reactant, titanium oxide (nanoparticles), an organic solvent, etc. are added to a urethane resin or an acrylic resin as a main material.

[0018] The coating film 30 can be obtained by placing a resin tape 40 (described later) on the exterior surface 6a of the exterior member 6, applying this easily peelable paint to the exterior surface 6a together with the resin tape 40 by spraying or brushing, etc., and then drying. When applying the easily peelable paint, the parts on which the coating film 30 is not to be formed may be covered with a masking material to prevent the easily peelable paint from adhering to them.

[0019] The resin tape 40 is a tape made of resin, and examples of the material thereof include polyethylene, polypropylene, and polyvinyl chloride, and is preferably a flexible tape.

[0020] The resin tape 40 may be surface-treated so as to have adhesion to the exterior surface 6a of the exterior member 6, or an adhesive may be provided on the surface that comes into contact with the exterior surface 6a. This allows the coating film 30 to be formed while maintaining the position of the resin tape 40 attached to the exterior surface 6a of the exterior member 6 during application of the easily peelable paint.

[0021] Furthermore, it is preferable that the tensile strength of the resin constituting the resin tape 40 is higher than the tensile strength of the material constituting the coating film 30. This makes it possible to prevent the resin tape 40 from being cut during peeling of the coating film 30, starting from the resin tape 40, as described below. Furthermore, since the thickness of the resin tape 40 can be made thin while ensuring such an effect, even if the coating film 30 is formed so as to cover the resin tape 40, the step caused by the thickness of the resin tape 40 can be made less visible.

[0022] Below, we will first briefly explain a front door outer 65 (hereinafter referred to as "door panel 65") as an example of an exterior member 6, and the coating film 30 and resin tape 40 provided on the exterior surface 65a of the door panel 65, with reference to Figures 2(a) to 3(a).

[0023] Fig. 2(a) is an enlarged cross-sectional view of a boundary portion between the door panel 65 and the door belt molding 77 (hereinafter referred to as "belt molding 77") shown in Fig. 1. Fig. 2(b) is a plan view of the door panel 65 shown in Fig. 1, and is a view for explaining the position of the resin tape 40. Fig. 3(a) is a cross-sectional view of a main portion of the door panel 65.

[0024] 2(a), the belt molding 77 is attached to the door panel 65 via attachments 90a and 90b. A resin tape 40A (40) is provided on the door panel 65 along the boundary adjacent to the belt molding 77.

[0025] 2(b), resin tapes 40B and 40C are provided on exterior surface 65a of door panel 65 so as to partition the surface area of ​​exterior surface 65a of door panel 65 along the front-rear direction of vehicle 1. Note that resin tapes 40B and 40C correspond to the "resin tape" of the present invention.

[0026] An exterior surface 65a of the door panel 65 is covered with the resin tapes 40A to 40C and the coating film 30. Here, of the coating film 30, the portion located above the resin tape 40B is the upper coating film portion 30a, the coating film located between the resin tapes 40B and 40C is the middle coating film portion 30b, and the portion located below the resin tape 40C is the lower coating film portion 30c.

[0027] As described above, the resin tapes 40A to 40C are preferably adhered (tightly attached) to the exterior surface 65a so as to be peelable. Furthermore, the resin tapes 40A to 40C are preferably adhered or bonded to the coating film 30 as well. The adhesive strength of the resin tape 40 to the coating film 30 is preferably higher than the adhesive strength of the resin tape to the exterior surface 65a. This makes it easier to partially peel off the coating film 30 together with the resin tape 40 from the exterior surface 65a of the door panel 65.

[0028] In this embodiment, for example, the resin tape 40A arranged along the boundary of the belt molding 77 may have a part exposed from the coating film 30 on the belt molding 77 side. This makes it easier to peel the coating film 30 from the exterior surface 65a starting from the exposed part of the resin tape 40A.

[0029] 2(b), of both end portions 40a, 40a of the resin tapes 40B, 40C, at least one end portion 40a serves as a starting point for partially peeling off the coating film 30. Therefore, of both end portions 40a, 40a of the resin tapes 40B, 40C, at least one end portion 40a may be exposed from the coating film 30. This makes it easier to partially peel off the coating film 30 from the exterior surface 65a, starting from the exposed portion of the resin tapes 40B, 40C.

[0030] Below, a method for peeling off the coating film 30 formed on the exterior surface 65a of the door panel 65 and a method for re-forming the coating film 30 on the surface from which the coating film 30 has been partially peeled off will be described with reference to Figures 3(b) and (c) as well as Figure 3(a) already described.

[0031] FIG. 3(b) is a schematic cross-sectional view showing a state in which the coating film 30 has been partially peeled off starting from the resin tape 40 from the state shown in FIG. 3(a), and FIG. 3(c) is a schematic cross-sectional view showing a state in which the coating film 30 has been re-applied to the exterior surface 65a of the door panel 65 from the portion in which the coating film 30 was peeled off from the state shown in FIG. 3(b).

[0032] First, when peeling off the entire coating film 30 from the entire exterior surface 65a of the door panel 65, the resin tape 40A provided along the boundary adjacent to the belt molding 77 is used. Specifically, the resin tape 40A is used as a starting point, and the resin tape is pulled down from top to bottom, so that the coating film 30 can be peeled off entirely from the exterior surface 65a. At this time, the resin tapes 40B and 40C are also peeled off together with the coating film 30. When the coating film is to be formed again, as described above, after placing the resin tape at a desired location, an easily peelable paint may be applied to the exterior surface 65a of the door panel 65 together with the resin tape.

[0033] Next, the resin tape 40B or the resin tape 40C is used to partially peel off the coating film 30 from the exterior surface 65a of the door panel 65. For example, when peeling off the upper coating film portion 30a of the upper part of the coating film 30 shown in FIG. 2(b), an operator pulls the resin tape 40B diagonally upward to the right starting from the end portion 40a of the resin tape 40B. This allows the upper coating film portion 30a of the coating film 30 to be partially peeled off, leaving the middle coating film portion 30b and the lower coating film portion 30c below the resin tape 40B, as shown in FIG. 3(b).

[0034] Furthermore, when re-forming the upper coating portion 30a, for example, a resin tape 40D is attached along the edge of the intermediate coating portion 30b, and an easily peelable paint is applied to the resin tape 40D and the exposed exterior surface 65a (upper surface) of the door panel 65.

[0035] When peeling off the intermediate coating film portion 30b and the lower coating film portion 30c of the coating film 30, the worker pulls the resin tape 40 diagonally downward to the right, starting from the end portion 40a of the resin tape 40B. This allows the intermediate coating film portion 30b and the lower coating film portion 30c of the coating film 30 to be peeled off, leaving the upper coating film portion 30a.

[0036] Similarly, starting from end portion 40a of resin tape 40C, the upper coating film portion 30a and the intermediate coating film portion 30b may be peeled off leaving behind the lower coating film portion 30c, and further, the lower coating film portion 30c may be peeled off leaving behind the upper coating film portion 30a and the intermediate coating film portion 30b.

[0037] In this way, for example, when the coating film 30 is partially damaged, it is possible to partially peel off the damaged coating film 30. Furthermore, by partially peeling off the coating film 30, the coating film 30 can be repaired by applying an easily peelable paint to the exposed surface of the exterior surface 65a of the door panel 65.

[0038] Furthermore, by partially peeling off the coating film 30 in a similar manner, and then applying an easily peelable paint of a different color to the coating film 30 to the exposed surface of the exterior surface 65a of the door panel 65 by partially peeling off the coating film 30, it is also possible to partially change the color of the coating film 30.

[0039] Here, the door panel 65 is exemplified as an exterior member to be provided on the exterior surface of the coating film 30 and the resin tape 40, but the present invention is not limited thereto, and may be applied to outer panels such as the hood panel 60, the roof panel 61, the trunk lid 62, the rear fender panel 64, the rear door outer 66, the front pillar 67, the center pillar 68, and the rear pillar 69. In addition, the present invention may be applied to exterior parts such as the front bumper cover 70, the rear bumper cover 71, the rocker panel molding 72, the door handle 73, the fuel filler cover 74, and the side mirror 75, which are exemplified as exterior parts among the exterior members 6.

[0040] For example, as shown in Fig. 4, it may be applied to a roof panel 61. Fig. 4 is a plan view of the roof panel 61 shown in Fig. 1, and is a diagram for explaining the position of the resin tape 40.

[0041] 4, resin tapes 40F, 40R are provided along a front edge 61f and a rear edge 61r of an exterior surface 61a of a roof panel 61. Here, resin tapes 40L, 40S are provided on the exterior surface 61a of the roof panel 61 so as to divide the surface area of ​​the exterior surface 61a.

[0042] A resin tape 40L is provided in the center of the exterior surface 61a of the roof panel 61 along the front-to-rear direction of the vehicle 1 so as to connect the front edge 61f and the rear edge 61r. Furthermore, a resin tape 40S is provided so as to connect the resin tape 40L to a side edge 61s of the roof panel 61. The exterior surface 61a of the roof panel 61 is covered with a coating film 30 together with the resin tapes 40L, 40S, 40F, and 40R.

[0043] In this way, when it is desired to peel off the entire coating film 30, resin tape 40F or resin tape 40R can be used, and when it is desired to peel off part of the coating film 30, resin tape 40L and resin tape 40S can be used.

[0044] Furthermore, when a convex stripe is formed on the exterior member 6, the resin tape 40 may be provided at the position shown in Fig. 5(a). Fig. 5(a) is a cross-sectional view showing the positional relationship between the exterior member 6 and the resin tape 40, and (b) is a cross-sectional view in which the coating film 30 has been partially peeled off starting from the resin tape 40 from the state shown in (a).

[0045] For example, as shown in Figures 5(a) and (b), in the case where a convex rib portion 6p is formed on an exterior member 6 and it is desired to peel off a portion 30g of the coating film 30 on one side across the convex rib portion 6p, a resin tape 40P can be provided on one exterior surface 6a adjacent to the convex rib portion 6p so as to be aligned with the convex rib portion 6p.

[0046] Furthermore, when it is desired to peel off the portion 30t of the coating film 30 covering the top surface 6q of the ridge portion 6t, a resin tape 40T may be provided to cover the top surface 6q of the ridge portion 6t. When it is desired to peel off the portion 30w of the coating film 30 covering the top surface 6y of the ridge portion 6w, which is wider than the ridge portion 6t, a resin tape 40W may be provided on one side of the width direction of the top surface 6y. Since the thickness of the portion 30e of the coating film 30 covering the edge of the top surface 6y is slightly thinner than the other portions, when it is desired to peel off the portion 30w of the coating film 30 starting from the resin tape 40W, the coating film 30 is easily torn at the portion 30e, and the portion 30w of the coating film 30 covering the top surface 6y can be easily peeled off.

[0047] As described above, according to the embodiment shown in Figures 1 to 5, the coating film 30 is formed by applying an easily peelable paint to an exterior member 6 such as the fender panel 13 of the vehicle 1, so that adhesion between the coating film 30 and the exterior member 6 of the vehicle 1 can be easily maintained.

[0048] Additionally, in this embodiment, the exterior surface 6a of the exterior member 6 is covered with the coating film 30 together with the resin tape 40, and the resin tape 40 is provided so as to define the surface area of ​​the exterior surface 6a. The resin tape 40 allows the coating film 30 covering the defined surface area to be partially peeled off, with the resin tape 40 as a definition. As a result, the coating film 30 applied to the exterior surface 6a of the exterior member 6 can be partially peeled off without peeling off the entire coating film 30.

[0049] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various design modifications can be made without departing from the spirit of the present invention as described in the claims.
