Description

  The present invention relates to a bumper spoiler that can be mounted on a bumper of a vehicle, a spoiler mounting structure, and a spoiler mounting method.

A bumper spoiler (also referred to as an air spoiler, chin spoiler, air dam, bumper skirt, under spoiler, etc., hereinafter simply referred to as a spoiler) is mounted on a front bumper of a vehicle such as an automobile. Such a spoiler can reduce the air resistance when the vehicle travels, thereby improving the fuel consumption of the vehicle.
As a known spoiler, for example, in Patent Document 1, when a plurality of insertion mounting portions formed integrally with a bumper spoiler main body portion are respectively attached to a plurality of insertion mounting holes formed in a bumper, a locking portion is attached. A bumper spoiler that can be elastically locked to at least one of the upper edge and the lower edge of the hole is described. In Patent Document 2, a core portion made of a hard resin is embedded in the mounting portion, and the surface thereof is covered with a soft resin, thereby strengthening the rigidity of the mounting portion. An under spoiler that can absorb the amount of expansion and contraction of the under spoiler is described. Patent Document 3 describes an invention in which an under spoiler includes a mounting portion having a lip and a fin portion, and at least the mounting portion is formed of a material having a linear expansion coefficient comparable to that of a front bumper. .

However, in both Patent Document 1 and Patent Document 2, in order to mount the spoiler, it is necessary to provide a plurality of mounting holes on the surface of the bumper at a predetermined interval in the width direction of the bumper. As a result, when two bumpers are set for the vehicle type with the spoiler and the bumper for the vehicle type without the spoiler, two separate molds are required to manufacture them. Furthermore, in a bumper having a mounting hole, a weld line that impairs the appearance quality tends to occur near the mounting hole when the bumper is injection molded.
In other words, when the spoiler is not attached to the bumper manufactured on the assumption that the spoiler is attached, the attachment hole is visually observed from the outside (particularly the front surface of the vehicle) and the decorativeness is impaired. Conversely, when the spoiler is mounted on a bumper manufactured on the assumption that the spoiler is not mounted, it is necessary to form the mounting hole in an additional process after the bumper is formed.
In addition, if the spoiler is not installed on a bumper manufactured on the assumption that the spoiler is installed, the air flow will be turbulent (turbulent flow or overflow) at the insertion hole while the vehicle is running, resulting in abnormal noise. There is a risk of generating.
Furthermore, when the attachment portion is formed on the spoiler, the attachment portion of the spoiler needs to be partially removed to form the attachment portion, so that an end material of the material is inevitably generated.

  Further, in the invention of Patent Document 3, since the mounting portion having a substantially U-shaped cross section simply sandwiches the bumper ridge from the vertical direction, there is a problem in long-term mounting stability. In addition, the lip (locking part) that locks onto the bumper is molded from a polymer material and is locked to the bumper using its elastic repulsive force, so that the lip creeps due to temperature changes during use. As a result, the elastic repulsive force is reduced, and there is a problem in the mounting stability over a long period of time, such as loosening of the mounting portion of the spoiler.

The main body part 105 is softer and more elastic than the leg part 110 from the viewpoint that the main body part 105 itself is prevented from being damaged even if the main body part 105 comes into contact with a road surface or a projection on the road surface while the vehicle 1 is traveling. It is preferable to mold from a high material.
Since the leg portion 110 attached to the receiving groove 7 formed in the bumper 5 needs to maintain a stable attachment state with respect to the bumper 5 even under a use environment with temperature change, It is preferable to mold from an elastic polymer material in which the linear expansion coefficient (linear expansion coefficient) in the direction (vehicle width direction) and the linear expansion coefficient in the longitudinal direction of the bumper 5 are the same. A preferable material from the viewpoint of availability is, for example, the same material as that of the bumper (that is, an extrusion-grade resin material mainly composed of a resin material obtained by adding a rubber component to polypropylene resin and further adding a large amount of filler). Can be mentioned. Thereby, even if there is a temperature fluctuation, the length of expansion and contraction of the bumper 5 and the spoiler 100 in the longitudinal direction is the same, so that the spoiler 100 does not generate longitudinal compressive stress or tensile stress. It will not be displaced from or removed from the receiving groove 7. Further, the leg portion 110 has a higher hardness and rigidity than the main body portion 105 and is fused and integrally formed with the main body portion 105 with a material compatible with the material of the main body portion 105 (typically two parts). (Color extrusion molding). As a preferable material, for example, when the main body is molded by EPDM which is a thermosetting polymer material, EPDM having higher hardness than the material of the main body is exemplified.

Next, the fixing tool 150 according to the present embodiment will be described with reference to the drawings. FIG. 7A is a front view showing the fastener 150 according to the first embodiment. FIG. 7B is a side view showing the fastener 150. FIG. 7C is a plan view showing the fastener 150.
The fixing tool 150 is a material that can maintain elasticity without creep deformation at a temperature (−30 ° C. to + 80 ° C.) at which the spoiler 100 is normally used (higher hardness and higher than the material that forms the leg 110). It is preferable to mold using a material having creep resistance and high elasticity. Typically, for example, a stainless steel spring steel plate, a metal plate including a spring steel plate subjected to rust prevention treatment such as galvanization, etc., or a material such as polyacetal resin, nylon (polyamide resin), etc. What was shape | molded by injection molding using the rich synthetic resin material is mentioned.

As shown in FIGS. 7A to 7C, when the fixing tool 150 according to the present embodiment is mounted in the housing concave groove 7 formed on the surface of the bumper 5, the upper side wall 9, the lower side wall 11, and the bottom wall are provided. 15 has an upper side portion 154, a lower side portion 158, and a bottom side portion 162 that come into contact (contact) with each other, and has a substantially U-shaped cross section. It is preferable that the inner surface shape of the cross section of the fixing device 150 before being mounted is slightly larger than the outer shape of the leg portion 110 and the outer surface shape is substantially the same as the inner surface shape of the housing groove 7. Since the upper side 154 and the lower side 158 have the same structure, the upper side 154 and the lower side 158 can be used in common even if they are reversed in the vertical direction.
At the end of the opening 30 side in the width direction of the upper side portion 154 (projection direction of the leg portion 110), the end of the upper side portion 154 on the opening 30 side in the width direction is bent in the direction of the lower side portion 158, thereby sharpening the tip. The first upper protrusions (first fixing portions) 155A and 155B having a substantially triangular shape (typically, a right triangle shape) are formed symmetrically. Similarly, first lower protrusions (first fixing portions) 159A and 159B are formed symmetrically on the opening 30 side end in the width direction of the lower side portion 158, respectively, and the first upper protrusions 155A and 155B The first lower protrusions 159A and 159B are opposed to each other.
In addition, in both longitudinal ends of the upper side portion 154 and the lower side portion 158, a second upper side obtained by cutting and raising a part of the upper side portion 154 and the lower side portion 158 into a substantially triangular shape (typically a right triangle shape). The protrusions (second fixing portions) 156A and 156B and the second lower protrusions (second fixing portions) 160A and 160B are formed symmetrically. The second upper projections 156A and 156B and the second lower projections 160A and 160B have an acute angle shape with the base portion 162 side as the base and the tip portion sharpened toward the opening 30, and the angle α toward the outer side from the fixing tool 150. Each is formed so as to protrude at an acute angle (for example, approximately 30 degrees). The positions where the second upper protrusions 156A and 156B and the second lower protrusions 160A and 160B are formed are not limited to the longitudinal ends of the fixing device 150, but are within the range of the upper side portion 154 and the lower side portion 158. It can be anywhere.

  The angle θ2 formed by the upper side portion 154 and the lower side portion 158 (the angle formed by the two-dot chain line in FIG. 7B) before mounting the fixing device 150 in the storage concave groove 7 is the storage concave portion. It is preferable to set the angle slightly larger than the angle θ1 (see FIG. 4) formed by the groove 7 (typically, an angle larger by about 5 degrees to 30 degrees). When the fixing tool 150 is mounted in the housing concave groove 7, the upper side portion 154 and the lower side portion 158 are elastically deformed in a direction in which the angle θ2 decreases (in the direction of arrow Y in FIG. 7B). As a result, the distance between the first upper protrusions 155A, 155B and the first lower protrusions 159A, 159B is reduced, and the protrusions 155A, 155B, 159A, 159B bite into the leg portions (fitting protrusions) 110, respectively. The fixing tool 150 is stably fixed (locked) to the spoiler 100. Furthermore, the upper side portion 154 and the lower side portion 158 attempt to restore in the direction of the arrow X in FIG. 7B by the respective elastic repulsive forces. As a result, the biting state of the second upper protrusions 156A, 156B and the second lower protrusions 160A, 160B with respect to the inner wall in the housing groove 7 is more stable, so that the fixing tool 150 is stably fixed to the bumper 5. Stop).

  As shown in FIG. 7A, a positioning hole (hole) 165 is formed in the bottom side portion 162 of the fixing tool 150 so as to penetrate the bottom side portion 162. The hole 165 is formed in a shape that can be fitted to the mounting portion side positioning protrusion 20 formed in the housing concave groove 7. By fitting the positioning protrusion 20 into the hole 165 and the removal portion 112, the spoiler 100 can be easily positioned in the longitudinal direction with respect to the bumper 5. Note that a positioning hole 165 is formed in the fixing tool 150 mounted at the center position of the spoiler 100 according to the present embodiment, and a positioning hole is formed in the fixing tool 150A mounted on the corner portion 5B or the end of the spoiler 100. 165 is not necessarily required, but even if it has the positioning hole 165, there is no problem.

Next, the mounting method and mounting state (mounting structure) of the spoiler 100 having the above-described configuration in the housing groove 7 formed on the surface of the bumper 5 will be described. The fixing tool is attached to at least the terminal in the longitudinal direction of the spoiler 100, but is preferably further attached to the center position of the spoiler 100, and more preferably, to a portion corresponding to the corner portion 5B as in the present embodiment. Is also installed.
As shown in FIG. 3, before attaching the spoiler 100 to the bumper 5 (attaching the leg portion 110 by fitting it into the receiving groove 7), the lengths of both ends in the longitudinal direction of the spoiler 100 (leg portion 110) are preliminarily set. The fixing device 150A is attached (fixed) to the leg portion 110 at the first position P1 and the second position P2 corresponding to the corner portion 5B of the bumper 5, and the leg at the third position P3, which is the center position in the longitudinal direction of the spoiler 100. A fixing tool 150 is attached (fixed) to the portion 110. Specifically, when the fixing tool is formed of a material such as a plastically deformable metal, an angle θ2 formed by the upper side 154 and the lower side 158 so that the legs 110 can be mounted in the fixing tools 150 and 150A. (See FIG. 7B) is adjusted in advance (the opening 30 of the fasteners 150 and 150A is formed to expand), and the legs 110 are fitted into the fasteners 150 and 150A, and the upper side portion is fitted with a tool or the like. 154 and the lower side portion 158 are plastically deformed in a direction in which θ2 is reduced (a direction in which the opening 30 of the fixing tool 150, 150A is reduced; a direction of arrow Y in FIG. 7B), and the first upper protrusion 155A of the fixing tool 150, 150A. , 155B and the first lower protrusions 159A, 159B are bitten into the leg portions (fitting protrusions) 110 and locked. Thereby, the fasteners 150 and 150A are attached to the leg portion 110. Alternatively, the upper side portion 154 can be mounted with a tool or the like so that the leg portion 110 can be mounted in the fixing tools 150 and 150A regardless of whether the fixing tool is molded from the material such as the metal or the synthetic resin having elasticity. And the lower side portion 158 are elastically deformed (in the direction of arrow X in FIG. 7B), and the leg portion 110 is fitted into the enlarged opening 30 to remove the tool or the like, thereby elastically moving the upper side portion 154 and the lower side portion 158. The fixing tools 150 and 150A are fixed (attached) to the legs 110 by a restoring force (recovered in the direction of arrow Y in FIG. 7B). When the fixing tool 150 is attached to the third position P3, the removal portion 112 formed in the leg 110 and the positioning hole 165 formed in the fixing tool 150 are attached so as to communicate with each other. The positioning projection 20 formed in the groove 7 can be fitted.

In a state in which the fasteners 150 and 150A are attached to the spoiler 100 (leg part 110), the first upper protrusions 155A and 155B and the first lower protrusions 159A and 159B formed on the fasteners 150 and 150A are the leg parts. (Fitting protrusion) Each bites into the surface of 110 and is locked. Accordingly, the fixing tools 150 and 150A are prevented from moving in the longitudinal direction of the spoiler 100 with respect to the spoiler 100 (specifically, the protrusions 155A and 159A cause the protrusions 155B of the fixing tools 150 and 150A to the spoiler 100). The movement in the direction of the protrusion 155A is blocked, and the movement in the direction of the protrusion 155B from the protrusion 155A is blocked by the protrusion 155B and the protrusion 159B, and the movement in the width direction (the protruding direction of the leg 110) is blocked. Therefore, the positional offset of the fixing tools 150 and 150A with respect to the spoiler 100 does not occur, and the fixing tools 150 and 150A are prevented from being detached from the spoiler 100.
As shown in FIGS. 5 and 6, the elastic lip 120 formed on the leg portion 110 is elastically deformed and is in contact with the fixing tools 150 and 150A (the back surface of the upper side portion 154). Due to the elastic restoring force (elastic repulsive force) of 120, the locking of the legs 110 (spoiler 100) to the fasteners 150, 150A is more stable.

  Next, the spoiler 100 is pressed into the housing concave groove (mounting portion) 7 of the bumper 5 at the third position P3 where the fixing tool 150 is mounted, and the fixing tool 150 is mounted on the bumper 5. Specifically, the positioning hole 165 of the fixing device 150 and the removal portion 112 of the leg portion 110 are fitted to the mounting portion side positioning protrusion 20 formed in the housing concave groove 7, and the second upper protrusion 156 </ b> A of the fixing device 150. , 156B and the second lower protrusions 160A, 160B are bitten into the housing concave groove 7 to attach the spoiler 100 to the bumper 5. As a result, the center position of the spoiler 100 in the longitudinal direction relative to the center position of the bumper 5 is positioned. Then, with the longitudinal tension applied to the spoiler 100, the spoiler 100 is pressed into the housing concave groove 7 of the bumper 5 at the second position P2 and the first position P1, and the second upper protrusion 156A of the fixing tool 150A, The spoiler 100 (fixing tool 150 </ b> A) is attached to the bumper 5 by causing 156 </ b> B and the second lower protrusions 160 </ b> A and 160 </ b> B to bite into the inner wall of the housing groove 7. By positioning the spoiler 100 in the longitudinal direction with respect to the bumper 5 at the third position P3, the spoiler 100 can be mounted symmetrically along the longitudinal direction of the bumper.

When the fasteners 150 and 150A are mounted in the receiving groove 7, the tip portions of the second upper projections 156A and 156B and the second lower projections 160A and 160B are directed toward the openings 30 of the fixtures 150 and 150A as described above. The protrusions 156A, 156B, 160A, 160B themselves do not get caught on the upper side wall 9 and the lower side wall 11 during mounting and can be easily pressed by pressing. 150A can be mounted in the receiving groove 7. Note that the upper side 154 and the lower side 158 of each of the fixing tools 150 and 150A mounted in the receiving concave groove 7 close the opening 30 by the pressing force from the upper side wall 9 and the lower side wall 11 of the receiving concave groove 7. Elastically deforms in the direction. Accordingly, the tips of the first upper protrusions 155A and 155B and the first lower protrusions 159A and 159B bite into the legs 110 more strongly.
In a state in which the fasteners 150 and 150A are mounted in the housing concave grooves 7 formed on the surface of the bumper 5, the second upper protrusions 156A and 156B and the second lower protrusion 160A formed on the fasteners 150 and 150A. , 160B bite into the inner surface (upper side wall 9 and lower side wall 11) of the receiving concave groove 7 and are locked (fixed). As a result, the fasteners 150 and 150A are prevented from moving in the longitudinal direction of the bumper 5 with respect to the bumper 5 (accommodating groove 7) (specifically, the protrusions 156A and the protrusions 160A fix the fasteners 150 and 150A. The bumper 5 is prevented from moving in the direction from the protrusion 156B to the protrusion 156A, and the protrusion 156B and the protrusion 160B are prevented from moving in the direction from the protrusion 156A to the protrusion 156B. Therefore, the fixing tools 150 and 150A are prevented from being disengaged from the bumper 5 without displacement of the fixing tools 150 and 150A with respect to the bumper 5.
As shown in FIG. 4, at a position where the fixing member is not attached to the leg portion 110, the leg portion 110 is fitted into the receiving concave groove 7 and the leg portion 110 is received by the elastic repulsive force of the elastic lip 120. Lock in the groove 7.
With this configuration, the bumper 5 does not need to be provided with a mounting hole for mounting the spoiler 100. Therefore, one type of bumper that does not have a mounting hole is commonly used for a vehicle model with a spoiler and a vehicle model with no spoiler. Can be used. Further, by attaching the spoiler 100 to the bumper 5 with the fixing tools 150 and 150A, a stable mounting state can be obtained.

As another mounting method, before the spoiler 100 is mounted on the bumper 5, the fixing tool 150 </ b> A is preliminarily placed in the first position P <b> 1 of both ends in the longitudinal direction of the bumper 5 (in the housing groove 7) and the corner portion of the bumper 5. At the second position P <b> 2 of 5 </ b> B, the fixing tool 150 is mounted at the third position P <b> 3 that is the center position in the longitudinal direction of the bumper 5. Specifically, the angle θ2 (see FIG. 7B) formed by the upper side portion 154 and the lower side portion 158 of each of the fixing tools 150 and 150A is adjusted to be larger than the angle θ1 (see FIG. 4) formed by the housing groove 7. In addition, the fixing tools 150 and 150A are attached to the corresponding positions by being pressed (fixed). When the fixing tool 150 is mounted at the third position P3, the positioning hole 165 of the fixing tool 150 is fitted into the mounting portion side positioning protrusion 20 formed in the housing groove 7 and mounted.
Next, the spoiler 100 is pressed against the fixing tool 150 attached to the third position P <b> 3 of the bumper 5, and the leg portion 110 of the spoiler 100 is attached to the fixing tool 150. Specifically, the removal portion 112 of the leg portion 110 is fitted to the positioning protrusion 20 passing through the positioning hole 165 of the fixing device 150 attached to the third position P3 of the bumper 5, so that the first of the fixing device 150 is fixed. The spoiler 100 is attached to the bumper 5 by causing the upper protrusions 155A and 155B and the first lower protrusions 159A and 159B to bite into the surface of the leg portion 110. Then, with the longitudinal tension applied to the spoiler 100, the spoiler 100 is pressed into the housing concave groove 7 of the bumper 5 at the second position P2 and the first position P1, and the first upper protrusion 155A of the fixing tool 150A, The spoiler 100 (leg part 110) is attached to the bumper 5 by causing 155B and the first lower protrusions 159A and 159B to bite into the surface of the leg part 110. Thereby, the effect similar to the said method is acquired.
