Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a bumper license lamp mounting device for illuminating a license plate placed on the bumper of a vehicle.

[Conventional technology]

Conventionally, as a bumper license lamp mounting device of this type, there has been known one as shown in FIG. 5, which is disclosed in, for example, Japanese Patent Laid-Open Publication No. 55-102738. Here, 1 is a vehicle body, 2 is a bumper attached to the front and rear of the vehicle body 1, 3 is a bumper strength member made of a rigid steel plate that constitutes the bumper 2, and 4 is a bumper strength member that covers the bumper strength member 3 to constitute the bumper 2. Bumper material made of flexible synthetic resin, 5 is a holder, 6 is a screw for attaching the bumper material 4 to the bumper strength member 3 by the holder 5, 7 is a lamp mounting bracket, 8 is a license lamp, 9 is a lamp installation The bracket 7 is attached to a boss portion 4a that protrudes from the bumper surface material 4.
Mounting screw to be attached to, 10 is license lamp 8
mounting screws to attach the lamp to the lamp mounting bracket 7,
Reference numeral 11 denotes a license plate, which is fixed in a recess formed in the center of the bumper surface material 4 of the bumper 2. Note that the reference numeral 12 indicates a driver used for attachment. In such a license lamp mounting device, the license plate 11 mounted in the center of the bumper 2 is attached to the lamp mounting bracket 7 on the bumper surface material 4.
It is illuminated by a license lamp 8 attached via a. However, if an impact is applied to the bumper 2, even if it is a light collision, the impact will also be applied to the license lamp 8 attached to the bumper surface material 4 via the lamp mounting bracket 7, causing the filament of the bulb to break, resulting in what is called a broken bulb. I had something to wake you up. If a ball breakage occurs, the bumper 2 must be removed from the vehicle body 1, the bumper surface material 4 and the bumper strength member 3 must be disassembled, and the mounting screws 9 must be removed, or the mounting screws 9 must be removed using a special tool. Therefore, maintenance work required a lot of man-hours and time. Also, after removing the lamp mounting bracket 7,
When the license lamp 8 is again attached to the lamp mounting bracket 7 with the mounting screws 10 and the lamp mounting bracket 7 is to be attached to the boss portion 4a of the bumper surface material 4 with the mounting screw, the resin boss portion 4
Since a was soft, it sometimes damaged the threads of the female thread. Furthermore, since the bumper surface material 4 is made of flexible synthetic resin and has low rigidity, the license lamp 8 will vibrate due to vibrations when the vehicle is running, and especially at high temperatures, the resin will soften and the license lamp 8 will vibrate.
license plate 1.
1 visibility deteriorates. Furthermore, since the boss portion 4a of the bumper surface material 4 made of synthetic resin is integrally molded, there is a problem in that the appearance quality is deteriorated due to sink marks. For this reason, a mounting device as shown in FIG. 6 has been proposed. In this mounting device, a lamp mounting bracket 7 for mounting a license lamp 8 with mounting screws 10 is mounted to the bumper strength member 3 made of steel plate of the bumper 2 by spot welding 9', and is connected to the bumper surface material 4 made of synthetic resin. has an interval δ. For this reason, even a very light collision will not cause the ball to break, and vibrations caused by vibrations when the vehicle is running will not occur. Furthermore, since there is no need to provide a boss portion 4a on the bumper surface material 4 made of synthetic resin, there is no sink mark.
The appearance quality of the bumper surface material 4 can be improved.

[Problem that the idea aims to solve]

In the license lamp mounting device improved as described above, since the lamp mounting bracket 7 is directly attached to the bumper strength member 3 made of steel plate in the bumper 2 by spot welding 9', the bumper surface made of synthetic resin may be damaged due to a light collision. If the member 4 is deformed by more than the distance δ, the lamp mounting bracket 7 will naturally also be deformed, requiring a large amount of repair costs. In this case, the bumper surface material 4 made of synthetic resin hits the lamp mounting bracket 7 and is damaged at the part A shown in the figure. Even if the lamp mounting bracket 7 is mechanically bonded to facilitate replacement, damage to the bumper surface material 4 made of synthetic resin cannot be avoided. It should be noted that if the strength of the lamp mounting bracket 7 is increased, such as by increasing the thickness of the lamp mounting bracket 7, in order to prevent the lamp mounting bracket 7 from being deformed, the collision that occurs in a light collision will become larger, which is undesirable. The above mounting device does not provide sufficient protection for the license lamp 8, and furthermore, if the lamp mounting bracket 7 is deformed in the event of a light collision, the entire bumper strength member 3 must be replaced, which increases repair costs. It was hot. Therefore, the present invention provides a license lamp mounting device for a bumper that can avoid damage to the license lamp as much as possible in the event of a light collision, can prevent damage to the bumper skin, and can easily replace the lamp mounting bracket at low cost. The purpose is to

[Means to solve the problem]

For this purpose, the present invention provides a license lamp mounting device for illuminating a license plate in a recess formed in a flexible bumper surface material covering a bumper strength member, which comprises an opening provided in the upper wall of the recess. In the license lamp mounting device for a bumper, in which a license lamp and a lamp mounting bracket are arranged in a closed space surrounded by a bumper surface material above the recess so as to illuminate the lamp through the bumper strength member, the lamp mounting bracket is attached to the bumper strength member. The base end is removably fixed at a location where work can be done through the opening, and the license lamp is supported at the tip with a predetermined distance from the bumper surface material. The method is to provide flexibility by forming a bent part so as to absorb the impact of time.

[Effect]

If the amount of elastic displacement of the bumper surface material is smaller than the predetermined distance between the bumper surface material and the license lamp during a light vehicle collision, the bumper surface material will not collide with the license lamp, so damage to the license lamp can be avoided as much as possible. . In addition, if the amount of elastic displacement of the bumper surface material is larger than the above-mentioned predetermined interval, the bumper surface material will collide with the lamp mounting bracket, but at that time, the lamp mounting bracket will bend and absorb the impact, so that the bumper surface material will Damage can be prevented. Further, since the lamp mounting bracket can be attached and detached from the bumper strength member from the outside through the opening provided in the upper wall of the recess of the bumper surface material, the license lamp and the lamp mounting bracket can be replaced easily and inexpensively.

In these figures, reference numeral 1 indicates a vehicle body, 2 indicates a bumper, 3 indicates a bumper strength member made of a rigid steel plate, and 4 indicates a bumper strength member made of a rigid steel plate.
5 is a bumper surface material made of flexible synthetic resin, 5 is a holder, and 6 is a screw. The bumper 2 is constructed by attaching the bumper surface material 4 to the bumper strength member 3 by the holder 5. Reference numeral 7 indicates a lamp mounting bracket, which is bent into two stages at a bending portion 7a so that it can be easily deformed by the impact of a light collision, and its tip 7b is made of synthetic resin. The bumper surface material 4 is bent roundly so as not to damage it. A license lamp 8 is attached to the tip 7b of the lamp mounting bracket 7 by fixing the license lamp socket with screws 10. An interval δ is provided. Also, the base end 7c of the lamp mounting bracket 7
is fixed to the bumper strength member 3 with screws 9. Reference numeral 11 indicates a license plate located at the lower center of the bumper 2 and installed in a recess 4a formed in the bumper surface material 4. Reference numeral 12 indicates a driver used during maintenance. The base end 7c of the lamp mounting bracket 7 is attached so that maintenance work can be performed using a screwdriver.
is fixed to the bumper strength member 3 at a location diagonally upward from an illumination opening 4b formed in the upper wall of the recess 4a. Hereinafter, the operation of the bumper license lamp mounting device of one embodiment configured as described above will be explained. First, if the vehicle has had a minor collision and the bumper surface material 4 made of flexible synthetic resin is not deformed beyond the distance δ from the tip end 7b of the lamp mounting bracket 7, the flexible bumper surface material 4 should be As shown in FIG. 3, the bumper surface material 4 made of a flexible synthetic resin deforms elastically to absorb the impact without damaging the license lamp 8, and returns to its original state with its own elasticity. On the other hand, when the bumper surface material 4 is elastically deformed beyond the predetermined interval δ, the bumper surface material 4 collides with the tip 7b of the lamp mounting bracket 7, but at this time the lamp mounting bracket 7 is deformed as shown in FIG. As it bends from the bending part 7a and absorbs the shock,
Damage to the bumper surface material 4 made of synthetic resin is prevented, and only damage to the license lamp 8 occurs. Also in this case, the bumper surface material 4 restores itself with its own elasticity. Here, the damaged license lamp 8 and the bent lamp mounting bracket 7 can be replaced without removing the bumper 2 from the vehicle body 1. That is, by inserting the driver 12 into the opening 4b made in the upper wall of the recess 4a of the bumper surface material 4 and removing the screw 9, the lamp mounting bracket 7 can be removed from the bumper strength member 3 with the license lamp 8 still attached. I can do it. Further, when only the bulb of the license lamp 8 is replaced due to a burnout, the license lamp 8 can be removed by operating the screwdriver 12 from the opening 4b and removing the screw 10.

[Effect of the idea]

As explained above, according to the present invention, if the amount of elastic displacement of the bumper surface material is smaller than the predetermined distance between the bumper surface material and the license lamp during a minor vehicle collision, the bumper surface material will not collide with the license lamp. Damage to the license lamp can be avoided as much as possible. In addition, if the amount of elastic displacement of the bumper surface material is larger than the above-mentioned predetermined interval, the bumper surface material will collide with the lamp mounting bracket, but at that time, the lamp mounting bracket will bend and absorb the impact, so that the bumper surface material will Damage can be prevented. Further, since the lamp mounting bracket can be attached and detached from the bumper strength member from the outside through the opening provided in the upper wall of the recess of the bumper surface material, the license lamp and the lamp mounting bracket can be replaced easily and inexpensively.
