Abstract

PURPOSE:To prevent the adhesion of ice and snow lumps by providing a heating means at a mud guard body installed directly behind the tire of a vehicle so as to catch muddy water or the like splashed by the tire. CONSTITUTION:Surface heating bodies 3 using metallic foil are embedded in a mud guard body 1. The respective surface heating bodies 3 are connected by conductors 4, and a cord 5 is connected to the conductors at both ends. During the operation of a heating means 2, water splash and snow flakes colliding with the mud guard body 1 are separated into water, snow and air while the energy is absorbed by protrusions 12, and water and snow are rapidly discharged downward being guided by drain ribs 9. In the mud guard body 1 with a plate part 13 formed, snow flakes and water splash splashed by a tire collide directly with this plate part 13 without colliding with a front member. The collision energy is absorbed by protruding parts 18 formed at the plate part 13, and the water and snow are discharged downward passing between the protruding parts 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle mudguard provided immediately after a vehicle tire.

[0002]

2. Description of the Related Art Conventional mudguards for vehicles are disclosed in Japanese Patent Application Laid-Open No. 60-12379 and Japanese Utility Model Laid-Open No. 62-88683.
The ones described in Japanese Patent No. 2,132,148A are known. These have been devised mainly to reduce the phenomenon in which the splash of the vehicle tires rolls up to form a fine mist as the traveling speed increases and spreads laterally or rearward of the vehicle, that is, the splash phenomenon.

[0003]

In the conventional mudguard, water is frozen or snow adheres to the front surface of the mudguard during traveling on a snowy road or in a climate below freezing. The ice blocks and snow blocks that had adhered to the mudguard dropped due to vibration during travel, which also hindered the travel of the rear vehicle. Also, if snowflakes or the like adhere, the effect of reducing splash will be significantly reduced.

Therefore, an object of the present invention is to provide a mudguard for a vehicle in which the adhesion of ice blocks and snow blocks is prevented.

[0005]

In order to achieve the above object, the present invention provides a heat generating means in a mudguard body which is installed immediately after a vehicle tire and receives muddy water splashed by the tire. .

[0006]

In the present invention, for example, the mudguard body is heated by operating the heat generating means during traveling on a snowy road, and even if the mudguard body in the heated state is snowed, it melts,
It does not happen that snowflakes adhere or fall.

The front surface of the mudguard body 1 is constructed as shown in FIGS. 6 and 7. The plurality of drain ribs 9
Both ends are gradually lowered downward from the central portion, and 8 rows are provided symmetrically in the vertical direction at regular intervals and above and below the drain ribs 9 between these drain ribs 9 and the uppermost row and the lowermost row. A plurality of protrusions 12 are formed on the. Further, the lower end of the mudguard body 1 is extended downward to form a thin plate-like portion 13 which is flexible and cuttable outside the projection area of the front member 6. On both side surfaces of the region where the drainage rib 9 is formed, a recess 14 is formed at a predetermined interval, and a long hole 15 and a mounting hole 16 are formed. By forming such a concave portion 14, thin portions are formed on both side surfaces of the mudguard body 1,
Provides flexibility. When attaching the front member 6 to the front surface of the mudguard body 1 via the plate 7,
When the front member 6 is extended upward along the inner curved surface of the tire house 11 (see FIG. 3), wrinkles tend to occur on the front member 6, but due to the presence of the concave portion 14, this portion bends and wrinkles. It is designed to prevent the occurrence of. In addition, the plate-like portion 13 is provided with a plurality of groove portions 1 along the horizontal direction and at a predetermined interval in the vertical direction (about 20 mm).
7 is formed. A plurality of convex portions 18 are formed between these groove portions 17. The protrusion 18 may be similar to the protrusion 12. The overall size of the mudguard body 1 is 375 mm in width and 445 mm in height, and the region where the drain rib 9 and the protrusion 12 are formed is 260 mm in width and 2 in height.
It was set to 52 mm. The groove 17 formed in the plate-shaped portion 13
May be a ridge.

The mudguard body 1 has a drainage rib 9 and a protrusion 1.
The area forming 2 and 2 has the dimensions as described above, and each rib 9
When the distance between the two is 42 mm, the protrusion 12 is 2000 to 30
00 pieces are formed. Although the projections 12 are shown only partially in FIG. 6, they are provided almost uniformly over the entire area described above. The projection 12 has a pin shape as shown in FIG. 7, and the projection 12 is formed higher than the drain rib 9. These protrusions 12 absorb energy,
The splash is separated into water and air, and all the separated water is guided by the drain ribs 9 and quickly discharged downward. Protrusion 12
Is preferably about 2 to 6 per cm ² , and if more is provided, the drainage efficiency at the location of the mudguard body 1 will be poor. Since both ends of the drainage rib 9 are lowered, the splash that has collided is dropped onto the road surface.

As shown in FIG. 8, the front member 6 is composed of a lattice-shaped member in which a vertical member 19 and a horizontal member 20 are combined, and the vertical member 19 is located on the front surface. The vertical member 19 has a triangular cross section, and the apex of the triangle is located on the front side. An opening 21 is formed between the vertical member 19 and the horizontal member 20. The distance a between the vertices of the triangles of the vertical member 19 was about 6.7 mm, the height b of the vertical member 19 was about 3.7 mm, and the length D of the bottom side of the vertical member 19 was about 3.3 mm. The thickness c of the lateral member 20 was about 2 mm.
The opening 21 has a long shape along the circumferential direction of the tire 10 in order to smoothly attract the splash from the tire 10. The cross section of the vertical member 19 has a triangular shape in order to sufficiently exert the splash reducing function.
The apex angle is preferably an acute angle of 90 degrees or less. The shape of the opening 21 is not limited to the rectangular shape, but can be various shapes.

It is preferably formed of a material such as a plastic elastomer.

As described above, in order to effectively prevent splash, it is preferable to attach the front member 6 as shown in FIG. 8 to the front surface of the mudguard body 1 as shown in FIG. With the structure, when the vehicle travels on a snowy road, the snowflakes bounced up by the tire 10 pass through the opening 21 and collide with the mudguard body 1, and the drainage rib 9 and a large number of protrusions 12 are formed on the mudguard body. Snowflakes tend to adhere to the surface of No. 1. Therefore, the effect of reducing splash and the effect of reducing snow smoke are reduced. Therefore, by operating the heat generating means 2 to raise the temperature of the front surface of the mudguard body 1 to 0 ° C. or higher, even if there are the drain ribs 9 and many projections 12, the splash of water freezes or snowflakes are attached to form ice blocks or snow blocks. Prevents adhesion. Heating means 2
When is operating, splashes and snowflakes collide with the mudguard body 1 and energy is absorbed by the projections 12, and the water and snow are separated from the air. The water and snow are guided by the drain ribs 9 and quickly discharged downward. To be done. In the mudguard body 1 having the plate-shaped portion 13, the splashes and snowflakes splashed by the tire 10 directly collide with the plate-shaped portion 13 without colliding with the front member 6. Collision energy is absorbed by the protrusions 18 formed on the plate-shaped portion 13,
It will be discharged downward through the space. Splashes and snowflakes that collide with the front member 6 are caused by the vertical member 19
Has a triangular cross-section, so sprays and snowflakes will have openings 2
It becomes easier to pass through 1 and it becomes difficult to return to the outside of the front member 6.

The plate-shaped portion 13 can be adapted to various heights of the tire house 11 by cutting it at the line groove portion. It may not be formed. Further, the mudguard body 1 can be used alone without providing the front member 6 on the front surface.
