Description

The present invention relates to a license plate holder attached to the front of an automobile body.

Safety technology in automobiles is evolving day by day, and technology for protecting pedestrians in the event of a collision is also being developed. Bumpers have a cushioning function that softens the impact in the event of a collision accident, and the bumper is usually joined to a bumper reinforcement having a high hardness. Therefore, when the bumper deforms due to the impact of a collision with a pedestrian, the impact energy of the high-hardness bumper reinforcement may be applied to the pedestrian. Pedestrians are then more susceptible to serious injuries such as bone fractures and knee ligament injuries.

Therefore, as a device that focuses on protecting pedestrians, a technology has been developed in which a shock absorbing member is placed between the bumper and the bumper reinforcement. The impact absorbing member may be arranged not only between the bumper and the bumper reinforcement, but also between the grille and the bumper reinforcement.

Arrangement of shock absorbing members is a technique useful for protecting pedestrians, but if some vehicle member that is difficult to deform exists between the pedestrian and the shock absorbing member, the presence of such vehicle member may cause serious injury to the pedestrian. There is a possibility that

In general, it is obligatory to attach a license plate (number plate) such as an automobile registration number table to the front of an automobile body, and some automobiles are known to have a license plate holder for holding the license plate. There is also known a technique for making the license plate holder easily deformable in order to absorb the impact at the time of collision.

Although Patent Document 1 relates to a rear license plate holder attached to the rear surface of an automobile body, it describes a technique in which the entire rear license plate holder is crushed in the event of a collision (see FIG. 2). Specifically, the left and right legs of the rear license plate holder body that connects the vehicle body and the rear license plate holder body are provided with crash beats or crash holes that are vulnerable to compressive loads, and the entire license plate holder is seated. Techniques to facilitate yielding have been described.

Patent Document 2 discloses a technique based on the assumption that a shock absorbing member is provided in front of the bumper reinforcement and a license plate holder is provided in front of the shock absorbing member, and the license plate holder is cut in the center in the vehicle width direction. Techniques for providing cutouts are described. The license plate holder described in the same document has a form in which the central portion is vertically bent at the time of collision.

By the way, it is important to incorporate technology related to pedestrian protection into the license plate holder, but on the other hand, design, rigidity against user pressure during car washing, prevention of fluctuations and wind noise during driving, etc. It is also important to consider the elements of

The technology described in Patent Document 1 is a shock buffering mode in which the entire license plate holder is crushed, and the technology described in Patent Document 2 is a shock buffering mode in which the central portion of the license plate holder is vertically bent. In either case, the upper and lower sides of the license plate holder are not in contact with the automobile body. Therefore, there is a lack of design that the mounting bracket is visible from the top of the license plate holder, lack of rigidity of the license plate holder as a whole against the pressure of the user when washing the car, and fluctuations during driving and wind noise. There are drawbacks such as generation.

The present invention has been made in view of such circumstances, and the upper flange protruding from the upper side of the license plate holder and the lower flange protruding from the lower side are in contact with the automobile body, and exhibit a new shock absorbing mode. Intended to provide a license plate holder.

a lower flange that protrudes from the lower side of the license plate holder main body toward the automobile main body and is in contact with the automobile main body,
The lower side has a portion where the lower flange does not exist.

The license plate holder of the present invention absorbs impact in a mode in which the lower flange is preferentially deformed in the event of a collision. In addition, the license plate holder of the present invention has an excellent design because the upper flange and the lower flange are in contact with the vehicle body, and the license plate holder has excellent rigidity as a whole, and also reduces fluctuations and wind noise during driving.

EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated. Unless otherwise specified, the numerical range "a to b" described in this specification includes the lower limit a and the upper limit b. Further, a numerical range can be configured by arbitrarily combining these upper and lower limits and the numerical values listed in the examples. Furthermore, a numerical value arbitrarily selected from within these numerical ranges can be used as the new upper and lower numerical values.

The license plate holder of the present invention is a license plate holder attached to the front of an automobile body,
A plate-shaped license plate holder main body,
an upper flange that protrudes from the upper side of the license plate holder main body toward the automobile main body and is in contact with the automobile main body;
a lower flange that protrudes from the lower side of the license plate holder main body toward the automobile main body and is in contact with the automobile main body,
The lower side has a portion where the lower flange does not exist.

Resin such as polypropylene is preferable as the material of the license plate holder of the present invention. It is preferable to use a resin in which a crystalline resin and an elastomer are combined.
Preferably, the license plate holder of the present invention is manufactured in a one-piece molding process.

The plate-like license plate holder main body holds the license plate by being combined with the license plate with its outer surface facing the back surface of the license plate. The license plate holder main body and the license plate are joined with their upper sides aligned, or the license plate is positioned within a range of 15 mm downward from the upper side of the license plate holder main body. It is preferable that they are connected with the upper sides of the .
It should be noted that the portion of the license plate holder main body that is connected to the license plate is preferably made of metal.

The area of the outer surface of the license plate holder body is approximately 1/5 to 2/3 or 1/4 to 1/2 of the area of the back surface of the license plate. The "area of the outer surface of the license plate holder main body" described here means the area surrounded by the upper, lower, left and right sides of the license plate holder main body. It also includes the area of the opening surface.
For reference, the size of a license plate on a typical Japanese car is 16.5 cm long and 33 cm wide, and the size of a license plate on a large car is 22 cm long and 44 cm wide.

The thickness of the license plate holder main body can be exemplified in the ranges of 1.5 to 3 mm and 1.7 to 2.7 mm.

Preferably, the upper side of the license plate holder main body is straight. If the upper side of the license plate holder main body is straight, a sense of uniformity with the shape of the license plate can be obtained.

There are no particular restrictions on the shape of the lower side of the license plate holder main body. Although the shape of the lower side may be linear, it is preferable to have a recessed shape in which the central portion of the lower side is positioned closer to the upper side than both ends of the lower side. By forming the lower side into a concave shape, the central lower portion of the license plate holder main body section is more likely to bend, so that the lower flange can be deformed more preferentially. Examples of the concave shape include an arc shape, the shape of an isosceles trapezoid with an upper base and a pair of legs, and the shape of a pair of equilateral triangles.

The upper flange protrudes from the upper side of the license plate holder body toward the automobile body. The vehicle body contact portion at the end of the upper flange in the projecting direction contacts the vehicle body when the license plate holder of the present invention is attached to the vehicle body.

It is preferable that the upper flange is formed continuously on the entire upper side in terms of design surface and deformation strength relationship with the lower flange. However, within the scope of the present invention, the upper side may have a portion where the upper flange does not exist. Examples of the ratio of the non-existing portion of the upper flange to the length of the upper side (R _upper ) are 0 to 30%, 0 to 25%, 0 to 20%, 0 to 15%, and 0 to 10%.

The thickness of the upper flange can be exemplified within the range of 1.5 to 3 mm and 1.7 to 2.7 mm.

The lower flange protrudes from the lower side of the license plate holder body toward the automobile body. The vehicle body contact portion at the end of the lower flange in the projecting direction contacts the vehicle body when the license plate holder of the present invention is attached to the vehicle body.
In addition, the lower flange is not continuous with the entire lower side of the license plate holder main body, and there are portions where the lower flange does not exist on the lower side.

Since there is a portion where the lower flange does not exist on the lower side, the rigidity of the lower flange side is low when the entire upper flange and the entire lower flange are compared. Therefore, when a force acts from the outer surface side of the license plate holder main body (when a force to the extent that the license plate holder buckles acts), the lower flange is preferentially deformed.

When the lower flange preferentially deforms, the automobile body contact portion at the end of the lower flange slides on the surface of the automobile body. As a result, the angle between the lower flange and the license plate holder body is larger than when installed. At this time, the license plate holder of the present invention is in a buckled state.

As a specific example of when the license plate holder buckles, a state in which the deformation angle between the lower flange and the license plate holder main body is larger than the deformation angle between the upper flange and the license plate holder main body can be exemplified.
Also, as a specific aspect of when the license plate holder buckles, the distance that the vehicle body contact portion at the end of the lower flange moves on the surface of the vehicle body is A state longer than the distance traveled on the surface can be exemplified.

The ratio (R _bottom ) of the non-existing portion of the lower flange to the entire length of the lower side of the license plate holder main body is 10 to 90%, 20 to 85%, 30 to 80%, 40 to 75%, 50 to 70. % can be exemplified.
R _upper and R _bottom satisfy the relationship R _upper < R _bottom .

Although the number of non-existing portions of the lower flange on the lower side is not limited, 1, 2, 3, 4, 5, and 6 can be exemplified. Although the number of lower flanges on the lower side is not limited, 1, 2, 3, 4, 5, and 6 can be exemplified.
From the standpoint of rigidity of the license plate holder, the lower flange is preferably present in the center of the lower side. Moreover, it is preferable that the lower flange and the portion where the lower flange does not exist are bilaterally symmetrical.

The surface shape of the lower flange may be rectangular or trapezoidal. Considering moldability during manufacture, it is preferable that the tapered shape tapers toward the automobile contact portion at the end.

The thickness of the lower flange can be exemplified within the range of 1.5 to 3 mm and 1.7 to 2.7 mm. Preferably, the thickness of the lower flange is less than the thickness of the upper flange.

The automobile body contact portion at the end of the lower flange preferably has a shape extending outwardly beyond the peripheral edge of the license plate holder body portion. Such a shape can be rephrased as an obtuse angle D formed between the license plate holder main body and the surface of the lower flange. By selecting such a shape, the lower flange can easily slide outward from the periphery of the license plate holder main body. Examples of the range of the angle D are 90°<D≦120°, 90°<D≦110°, 93°≦D≦105°, and 95°≦D≦100°.

The license plate holder body is mounted at an angle of 80 to 100° with respect to the ground when mounted on the vehicle body such as the grille or bumper.
The length of protrusion of the upper flange from the upper side of the license plate holder main body toward the automobile body (L _upper ) and the length of protrusion of the lower flange from the lower side of the license plate holder main body toward the automobile main body (L _bottom ) are It is designed so that the angle of the license plate holder body with respect to the ground is 80-100°, depending on the angle of the grill or bumper to be installed with respect to the ground.
Therefore, L _upper and L _bottom can have any relationship of L _upper >L _bottom , L _upper =L _bottom , and L _upper <L _bottom .

A flange with a long flange projection length has a longer movement distance of the contact portion of the automobile body at the end of the flange than a flange with a short flange projection length when the angle variation at the time of collision is the same. Therefore, in order to increase the degree of deformation of the lower flange, it is preferable that L _upper and L _bottom satisfy the relationship L _upper <L _bottom .

The lower side of the license plate holder main body portion may be provided with a convex portion that protrudes from the lower side of the license plate holder main body portion toward the automobile main body but does not come into contact with the automobile main body. Due to the presence of the protrusion, the rigidity of the license plate holder main body is improved, so that the handleability of the license plate holder is improved during manufacturing and installation work.

The left and right sides of the license plate holder body preferably have left and right flanges that follow the shape of the grille or bumper and contact the grille or bumper. The left and right flanges may be designed such that their tips extend outward beyond the periphery of the license plate holder main body.
The left and right flanges may be continuous with the upper and lower flanges. The boundaries between the left and right flanges and the lower flange are preferably designed to be thin, and may be provided with grooves extending in the projection direction of the flanges.

The license plate holder of the present invention is attached to the front grille or bumper of the automobile body by fastening members.
The license plate holder main body has a mounting portion through which the fastening member penetrates and is mounted in contact with the front surface of the vehicle body. As the number of attachment portions, 2 to 4 can be exemplified, and 2 is preferable. It is preferable that the mounting portions are provided symmetrically in the upper half region of the license plate holder main body. By providing the mounting portion in the upper half region of the license plate holder main body, the lower flange can be deformed more preferentially.

The shape of the mounting portion is not limited, but a quadrilateral base is preferable so that the license plate holder body can be easily deformed toward the lower side. In addition, it is preferable that the mounting portion is provided with a fragile portion such as an opening so that it can easily buckle toward the lower side.

The license plate holder body has an alignment part for facilitating alignment during installation, and an auxiliary flange for increasing the rigidity of the license plate holder body within the scope of the present invention. may It is preferable that the positioning portion and the auxiliary flange also have a shape that easily buckles toward the lower side.

Since the license plate holder of the present invention absorbs impact in a mode in which the lower flange is preferentially deformed at the time of collision, pedestrian leg protection performance is ensured. Therefore, the license plate holder of the present invention is useful for suppressing shear fractures near the knees of pedestrians who have been hit, and for the medial collateral ligament connecting the femur and the tibia, the lateral collateral ligament connecting the femur and the fibula, and the knee. It can be said to be useful for protecting the anterior cruciate ligament and posterior cruciate ligament inside the joint.
