Description

[Technical field]

[0001] The present invention relates to a wiring cover for a vehicle that covers a wiring portion exposed inside the vehicle in a wiring path between a heating conductor (heating wire) for anti-fogging arranged on a windshield and a power source. [Background technology]

[0002] A heating conductor called a defogger is printed in a specific pattern on the windshield of a vehicle to prevent fogging during rainy weather, etc. (see, for example, Patent Document 1). The wiring path between this heating conductor and the power source is usually covered with interior trim (lining) such as plastic, and is not visible inside the vehicle. However, in some types of vehicles, such as commercial vehicles, from the perspective of reducing costs, etc., the completed form is such that the area from the power cord outlet of the inner panel to the connection part of the heating conductor printed on the rear windshield is left exposed. The inner panel is generally made of a thin steel plate, and this inner panel is also left exposed without being covered by the lining.

[0003] The space on the rear door (back door) side is often used as a luggage compartment, and if the wiring is exposed as described above, there is a risk of it being disconnected when loading or unloading luggage, or if the luggage falls over. This also makes the interior space of the car look inferior.

[0004] To address this issue, wiring covers that cover exposed wiring are commercially available. These wiring covers are made up of a pair of left and right wires, and have a symmetrical appearance with a bent L-shape, with a gutter-shaped cavity inside. Double-sided tape is provided around almost the entire edge of the bottom surface, and the adhesive strength of the double-sided tape allows the cover to be fixed to the surface of the inner panel. By covering the exposed wiring with this wiring cover, it is possible to protect the exposed wiring and prevent a decrease in the interior appearance. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2012-191393 A Summary of the Invention [Problem to be solved by the invention]

[0006] The above commercially available wiring covers need to be fixed while maintaining symmetry between the left and right sides from the perspective of interior design, but since it is difficult to reattach them using double-sided tape, it is necessary to accurately position the cover before attaching it, which is time-consuming. In addition, this type of vehicle has low insulation, so if you stay in the car overnight, condensation may form inside the car in the morning, and in this case, water droplets may accumulate inside the wiring cover. However, in addition to the fact that it is not possible to clean the inside of the wiring cover, there is a problem that even if you want to clean the area around the wiring cover in the rear door, it is difficult to remove the wiring cover, leaving some areas that cannot be cleaned.

[0007] The present invention has been made in consideration of the above-mentioned points, and its object is to provide a wiring cover for a vehicle that can be easily corrected if its fixed position is misaligned, and that can also be easily removed for cleaning. [Means for solving the problem]

[0008] In order to achieve the above object, the vehicle wiring cover (16L, 16R) of the present invention is a vehicle wiring cover (16L, 16R) that covers an exposed wiring portion (24) that is exposed in an exposed state from a cord exit of an inner panel (14) made of a magnetic material to a connection portion of the heating conductor (6) in a wiring path between an anti-fogging heating conductor (6) arranged on a rear window glass (4) and a power source that supplies electricity to the heating conductor (6) via a cord (18), and is characterized in that the vehicle wiring cover (16L, 16R) includes a cover body (26) made of synthetic resin that covers the exposed wiring portion (24), a magnet (28) that is fixed to the side of the cover body (26) facing the inner panel (14) and is attracted to the inner panel (14), and a surface material (30) that is provided on an attraction surface (28a) of the magnet (28) and has a larger friction coefficient than the attraction surface (28a) and is soft, and can be freely attached to and detached from the inner panel (14) by magnetic force.

[0009] According to the vehicle wiring cover of the present invention, since it is fixed by magnetic force, it can be easily corrected even if it is misaligned, and it is also easy to remove for cleaning. In addition, since the magnetic attraction surface is not directly in contact with the inner panel but is attracted via a surface material with a large friction coefficient, it is difficult to be misaligned even if a horizontal (lateral) external force is applied, and the fixed state can be stably maintained. In addition, since the surface material is soft, there is no need to worry about damaging the surface (coating surface) of the inner panel.

[0010] In the vehicle wiring cover (16L, 16R), the magnet (28) may be a neodymium magnet, which can increase the attraction force and provide a stable fixed state.

[0011] In addition, in the vehicle wiring cover (16L, 16R), the surface material (30) may be a silicone sheet that is attached to the adhesive surface (28a). This can prevent a decrease in the adhesive force in the horizontal direction (lateral direction) and eliminates the risk of damaging the surface (paint film) of the inner panel.

[0012] In the vehicle wiring cover (16L, 16R), the cover body (26) may include a connector (22) connected to the heating conductor (6), a first cover part (26A) that covers a part of the cord (18) extending from the connector (22) along the window frame (12) of the rear window glass (4), and a second cover part (26B) that communicates with the first cover part (26A) at a substantially right angle and covers the cord (18) up to its cord outlet, and the magnet (28) is fixed to the bottom side of the second cover part (26B). In this way, by fixing the magnet to the side that is placed on the inner panel, it is possible to stably and efficiently obtain adhesion and fixation by magnetic force.

[0013] In the vehicle wiring cover (16L, 16R), the magnets (28) may be formed in a rectangular plate shape elongated in the longitudinal direction (arrow Y1 direction) of the second cover part (26B), and two magnets (28) may be fixed to the bottom surface of the second cover part (26B) at an interval in the longitudinal direction (arrow Y2 direction) of the first cover part (26A). This allows stable attraction and fixation with a small attraction area.

[0014] In the vehicle wiring cover (16L, 16R) described above, each magnet (28) may be fixed to a rib (32) integrally formed with the second cover portion (26B) with a screw member (34), and the head of the screw member (34) may not protrude from the attraction surface (28a). This allows the surface material that comes into contact with the inner panel to be flat, and a stable attraction force can be obtained. Effect of the Invention

[0015] According to the present invention, even if the fixing position is misaligned, it can be easily corrected, and it can also be easily removed for cleaning. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018] FIG. 1 is a partially omitted view of a rear door 2 of a light vehicle (off-road four-wheel drive vehicle) as an example of a vehicle, seen from the inside of the vehicle. A plurality of heating wires (heating wires) 6 extending in parallel in the horizontal direction are printed in a predetermined pattern on the rear window glass 4, forming a defogger 8. Both ends of these heating wires 6 are connected to strip-shaped conductors (bus bars) 10L and 10R. The rear window glass 4 is supported by a window frame 12, and an inner panel 14 made of a magnetic thin steel plate is exposed around the window frame 12. Below both sides of the rear window glass 4, vehicle wiring covers 16L and 16R according to this embodiment are detachably fixed to the flat surface of the inner panel 14 by magnetic force. Hereinafter, the vehicle wiring cover 16L will be abbreviated as the left wiring cover 16L and the vehicle wiring cover 16R will be abbreviated as the right wiring cover 16R as appropriate.

[0019] 2, when not covered by the left wiring cover 16L, a cord (wire harness) 18 from a power source (not shown) is exposed to the outside from the inner panel 14 through a grommet 20, and can be seen to be connected to the terminal 10a of the strip-shaped conductor 10L through a connector 22. That is, in the wiring path between the heating conductor 6 for defogging arranged on the rear window glass 4 and a power source (not shown) that energizes the heating conductor 6 through the cord 18, there is an exposed wiring portion 24 that is exposed in a bare state from the portion of the grommet 20, which is the cord outlet of the inner panel 14, which is a magnetic material, to the connection portion of the heating conductor 6, i.e., the terminal 10a of the strip-shaped conductor 10L to which the connector 22 is connected.

[0020] The left wiring cover 16L and the right wiring cover 16R also have similar exposed wiring portions 24 (see FIG. 7). That is, the left wiring cover 16L and the right wiring cover 16R are vehicle wiring covers that cover the corresponding exposed wiring portions 24.

[0021] As shown in Fig. 3 (a perspective view from the top) and Fig. 4 (a perspective view from the bottom), the left wiring cover 16L includes a synthetic resin cover body 26 that covers the exposed wiring portion 24, a magnet 28 that is fixed to the side (bottom side) of the cover body 26 that faces the inner panel 14 and is attracted to the inner panel 14, and a silicone sheet 30 that is provided on an attracting surface 28a (see Fig. 5) of the magnet 28 and serves as a soft surface material with a higher friction coefficient than the attracting surface 28a, and is detachable from the inner panel 14 by magnetic force. The magnet 28 is a neodymium magnet with a high attracting force, and the silicone sheet 30 is attached to the attracting surface 28a. The inside of the cover body 26 is a trough-shaped cavity (a protective space for the cord 18, etc.).

[0022] The cover body 26 includes a connector 22 connected to the heating wire 6, a first cover portion 26A that covers a part of the cord 18 extending from the connector 22 along the window frame 12 of the rear window glass 4, and a second cover portion 26B that communicates with the first cover portion 26A at a substantially right angle and covers the remaining part of the cord 18 up to the grommet 20, which is the cord outlet, and the magnets 28 are fixed to the bottom surface side of the second cover portion 26B. The magnets 28 are formed in a rectangular flat plate shape that is elongated in the longitudinal direction (arrow Y1 direction) of the second cover portion 26B, and two magnets 28 are fixed to the bottom surface side of the second cover portion 26B at intervals in the longitudinal direction (arrow Y2 direction) of the first cover portion 26A. Each magnet 28 is screwed to a rib 32 integrally formed with the second cover portion 26B at two points at intervals in the arrow Y1 direction by screws 34 as screw members, and the heads of the screws 34 do not protrude from the suction surface 28a. 3 and 4, reference numerals 27a and 27b denote recesses (notches) for avoiding interference with the window frame 12. In FIG.

[0023] The screw fastening configuration of the magnet 28 will be described in detail with reference to Fig. 5. Fig. 5 is an enlarged cross-sectional view of the main part taken along the line XX in Fig. 3 and Fig. 4. Since the shape of the second cover part 26B is slightly oblique, the positions of the two magnets 28 are also shifted in the direction of the arrow Y1, and only the screw fastening portion of the magnet 28 on the left side of Fig. 4 (right side of Fig. 3) is shown in cross section.

[0024] Each rib 32 is formed in a plate shape extending inward from the inner surface 26a-1 of the side plate 26a of the second cover part 26B, and a cylindrical part 32a is integrally formed in the center. A screw 34 is screwed into a screw hole 32a-1 formed in the cylindrical part 32a. The magnet 28 is formed with a head receiving hole 28b having a trapezoidal (tapered) cross section for receiving the head of the screw 34, and a straight insertion hole 28c communicating with the head receiving hole 28b. When screwed, the head of the screw 34 is flush with the adsorption surface 28a or slightly recessed from the adsorption surface 28a. The head of the screw 34 and the head receiving hole 28b are covered with a silicon sheet 30, and only the silicon sheet 30 comes into contact with the inner panel 14.

[0025] Since the attractive surface 28a of the magnet 28 has a dense and smooth surface texture that is almost mirror-finished, if it is brought into contact with the inner panel 14 and attached and fixed as is, it will slide easily in the lateral (horizontal) direction due to reduced contact friction. It is known that the attractive force of magnetism is strong in the vertical direction, but decreases to, for example, about 1 / 5 in the horizontal direction perpendicular to the vertical direction. If an unexpected horizontal external force acts on the left wiring cover 16L due to a hit by luggage or the like, causing the left wiring cover 16L to shift position in the horizontal direction, there is a possibility that the cord 18 will break due to the impact.

[0026] For this reason, a silicon sheet 30 having a larger coefficient of friction than the adsorption surface 28a is attached to the adsorption surface 28a to increase the frictional force between the adsorption surface 28a and the inner panel 14, thereby suppressing horizontal positional deviation. The silicon sheet 30 is thin, about 0.5 mm, so it has almost no effect on the decrease in magnetic force (adsorption force). The thickness of the silicon sheet 30 is set so that the end surface 26a-2 on the bottom side of the second cover portion 26B is slightly raised from the inner panel 14 so that the bottom surface of the second cover portion 26B does not directly contact the inner panel 14 and inhibit the function of the silicon sheet 30 in suppressing horizontal positional deviation.

[0027] If the attraction surface 28a of the magnet 28 were to come into direct contact with the surface of the inner panel 14, there would be a risk of the surfaces of the two metals coming into contact and being damaged, but since the soft silicone sheet 30 is in contact with the surface, this is not a concern.

[0028] FIG. 6 shows the state in which the exposed wiring portion 24 is covered with the left wiring cover 16L, that is, the use state shown in FIG. 1. The left wiring cover 16L is attracted and fixed by magnetic force simply by placing the second cover part 26B on the flat surface 14a of the inner panel 14. With this one-touch fixation, the terminal 10a of the strip conductor 10L, the connector 22, and a part of the cord 18 are covered with the first cover part 26A together with a part of the window frame 12, and the remaining part of the cord 18 up to the grommet 20 is covered with the second cover part 26B. That is, the exposed wiring portion 24 can be covered and protected by the simple operation of one-touch fixation by magnetic force, and at the same time, deterioration of the appearance (interior quality) due to the exposed wiring can be suppressed. There is no trouble of accurately determining the arrangement position as in the method of fixing with double-sided tape.

[0029] If the cover is misaligned, it can be easily corrected any number of times, and it can be easily removed for cleaning, so cleaning can be done without leaving any uncleaned areas. In other words, even if condensation droplets adhere to the inside of the cover, it can be removed and wiped, and when removed, the entire fixing area of ​​the inner panel 14 can be wiped without any obstacles. Unlike double-sided tape, no adhesive marks are left behind after removal. After cleaning is completed, it can be fixed again with one touch by simply placing it in the specified position on the inner panel 14.

[0030] As described above, in this embodiment, the inner panel 14 made of a thin steel plate as a magnetic body is exposed, and the vehicle wiring covers 16L, 16R are easily fixed by magnetic force. In addition, a surface material with a large friction coefficient is provided on the attraction surface 28a of the magnet 28 to suppress a decrease in the attraction force in the horizontal direction.

[0031] Although the left wiring cover 16L has been described above as a representative example, the right wiring cover 16R is similar except that the orientation is reversed, and is indicated by the same reference numeral as shown in Fig. 7. Since there is a difference (asymmetry) in the shape, etc. of the flat surface 14a of the inner panel 14 on the left and right sides of the rear window glass 4, there is a slight difference in dimensions between the left wiring cover 16L and the right wiring cover 16R, but there is almost no difference in appearance in terms of left-right symmetry from the viewpoint of interior design.

[0032] Since it is difficult to reattach the cover using double-sided tape, even if the left-right symmetry is lost, the cover must be left as it is, resulting in a decrease in the interior design quality. In contrast, the left wiring cover 16L and the right wiring cover 16R according to this embodiment can be easily and arbitrarily corrected if there is a misalignment, so that it is easy to adjust the balance of the left wiring cover 16L and the right wiring cover 16R in terms of left-right symmetry, which also contributes to improving the interior design quality.

[0033] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible within the scope of the claims and the technical ideas described in the specification and drawings. For example, the shape of the cover body 26 is not limited to the above, and can be appropriately modified in design as long as it can cover and protect the exposed wiring part 24. The shape of the magnet 28 is also not limited to the above, and can be appropriately modified in design as long as a predetermined attractive force is obtained. The surface material is also not limited to the silicone sheet 30, and other synthetic resins, rubber-based materials, etc. can be appropriately used as long as they do not damage the surface of the inner panel 14. Furthermore, the fixing of the magnet 28 to the second cover part 26B is not limited to screws, and may be fixed by adhesive. [Explanation of symbols]
