Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an improvement of a vehicle muzzle guard.

[Conventional technology]

Conventionally, as shown in FIG.
A vehicle mound guard 5 is installed to prevent the fender panel 4 from getting dirty or damaged by splashes thrown up by the tires 3 while the vehicle is running.

In such a vehicle muzzle guard 5, a resin muzzle guard main body 11 having a predetermined rigidity is attached to a flange 6 formed by bending along the opening edge of the wheel house 2 with a fixing member (not shown) such as a bolt. It is installed and fixed (utility development 57-189981)
(see publication).

[Problems with conventional technology]

By the way, as shown in FIG. 6, when the automobile 1 is backing up, there are cases where the rear wheels or the front wheels end up riding on a large protrusion 8 such as a sidewalk curb due to an incorrect operation. In such a case, the mudguard main body 11 is sandwiched between the tire 3 and the protrusion 8, and as the tire 3 rotates in the opposite direction, the driving force of the tire 3 is transmitted to the mudguard main body 11, resulting in a very large Since the vehicle body is pulled downward by the force, stress acts on the mounting portion of the vehicle muzzle guard 5, and the fender panel 4 and the like of the vehicle 1 may be deformed.

In order to prevent such a situation, for example,
As shown in the figure, a groove 10 is formed along the width direction in the muzzle guard body 11, or a plurality of holes are formed so that the muzzle guard 5 for the vehicle is sandwiched between the tire 3 and the protrusion 8. When the vehicle muzzle guard 5 is pulled downward from the vehicle body due to the reverse rotation of the tires 3, the vehicle muzzle guard 5 is pulled into the groove 10.
Alternatively, it is conceivable that the fender panel 4 is broken at the hole to prevent deformation of the fender panel 4, etc., but this has the disadvantage that it looks bad and the quality of the appearance deteriorates.

Therefore, the technical problem of this invention is that when a car accidentally runs over a large protrusion such as a sidewalk curb when reversing, and the muzzle guard is caught between the protrusion and the tire, the driving force of the tire is lost to the muzzle guard. The object of the present invention is to effectively prevent deformation of a vehicle body panel caused by the mudguard being pulled downwards from the vehicle body without impairing the appearance quality.

[Technical means to solve problems]

In order to solve such technical problems, in the present invention, a concave portion is provided by cutting out the upper part of the mud guard main body at the portion facing the tire, and a recess is provided on both sides of the concave portion in the width direction of the mud guard main body. Through holes in the fixing member are opened across the recess, and each through hole is provided with a slit extending into the recess and having a width narrower than the diameter of the through hole.

[Effect]

Therefore, in the vehicle mound guard according to the present invention, the through holes of the fixing member provided on both sides of the notched recess of the mud guard main body are provided with slits extending to the notched recess, so that when the vehicle backs up, If the Mazudo guard body is caught between the tire and a protrusion on the road surface, and the driving force of the wheel is transmitted to the Mazudo guard body, and the Mazudo guard body is pulled downwards by a very large force, it will act on the Mazudo guard body. Stress is concentrated in the through hole of each fixing member. Since the slit provided in the through hole is close to the recess, first, a break occurs between the slit and the recess. After that, if the driving force of the wheel acts on the mudguard body,
The fracture progresses from the through hole toward the side end of the mudguard body, and eventually the mudguard body is completely fractured in the width direction.

Vehicle muzzle guard 12 configured in this way
In this case, the mud guard body 13 is
is sandwiched between the tire 3 and a protrusion 8 such as a sidewalk curb, and the driving force of the tire 3 is transferred to the mud guard body 1.
3 and the mudguard main body 13 is pulled downward with a very large force, the stress acting on the mudguard main body 13 is transmitted to the through holes 24, 27, 29, 30 of the rivet 15 as a fixing member and the tapping. Through holes 25, 46 of screw 16
Concentrate on. In this case, since the through hole 27 of the mud guard main body 13 communicates with the recess 18 via the slit 26, when the mud guard main body 13 is pulled downward, the rivet 15 of the through hole 27 is relatively connected. It moves to the recess 18, and the fixation in the through hole 27 is released.

On the other hand, only the through hole 24 is formed in the vehicle body internal fixing part 52 and it is fixed with only one rivet 15, and is not fixed at multiple locations like the vehicle body external fixing part 53, so that it cannot be fixed inside the vehicle body. Direction fixing part 52
In this case, the tensile load is concentrated only on the through hole 24. Since the slit 26 provided in the through hole 24 of the rivet 15 provided in the internal fixing portion 52 of the vehicle body is provided very close to the recess 18, the slit 26 and the short side 19 of the recess 18
Fracture occurs due to the application of a tensile load, and the fixation of the vehicle interior fixing portion 52 is released. Then, as the tire 3 rotates, the mudguard main body 13 is further pulled downward, so that the downward tensile load of the vehicle body is concentrated on the through hole 25, which is the lowest fixed part of the vehicle body outer side fixing part 53. do. In this case, since the slit 31 provided in the through hole 25 is provided very close to the recess 18, breakage occurs between the slit 31 and the short side 20 of the recess 18. The fracture that occurs between the slit 31 and the recess 18 progresses toward the outer edge 54 of the mound guard body 13, and then, as shown in FIG. 4, the mound guard body 13 is completely fractured. , falling off the vehicle.

In addition, in this embodiment, the muzzle guard body 1
3 is fixed to the vehicle body via the mounting member 14, but the invention is not limited to this embodiment, and it may be fixed directly to the wheel house without using the mounting member.

[Effect of idea]

Since the present invention has the above configuration,
When a car accidentally runs over a large protrusion such as a curb on the sidewalk when reversing, the muzzle guard gets caught between the protrusion and the tire, and the driving force of the tire is transmitted to the muzzle guard, causing the muzzle guard to be pulled downwards. This can cause the muzzle guard to break in the width direction and fall off from the vehicle body. Therefore, it is possible to prevent the situation in which the mud guard is pulled downward by the driving force of the tires, which causes a tensile load to be transmitted to the vehicle body, causing the vehicle body panel to deform. Furthermore, the arrangement of the through-holes in the fixing member and the slits provided in the through-holes do not make it easier to break by providing a groove or a hole across the width of the body of the mudguard. It is possible to prevent the appearance quality from deteriorating as in the conventional case.
