Abstract

PURPOSE:To prevent a breakage of an electron circuit unit, by installing it inside a car bumper through holding members which are broken or deformed by an outer impact, and making the said unit drop when an outer impact is given to the bumper. CONSTITUTION:When an electron circuit unit 2 is installed inside a car bumper 1, a base member 4 is fixed with a bolt 5 or the like to an upper side bumper face 3 of the bumper 1, as well as a hook member 7 of a spring which cooperates with the base member 4 is united to the side of a frame 6 to hold the said unit 2. And the said unit 2 is installed by gearing the hook member 7 to the base member 4. In such a structure, if an outer impact is given, the hook member 7 is removed from the base member 4, and the said unit 2 is to drop together with the holding frame 6. Therefore, a breakage of the said unit owing to a deformation of the bumper 1 can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for mounting an electronic circuit unit to a vehicle body.

Recently, an object detection device has been developed that detects obstacles in the direction of travel of the car by attaching an object sensor to a part of the bumper of the car. When the electronic circuit unit 2 is installed in the same bumper 1 to which the sensor is mounted, it is conceivable to install the electronic circuit unit 2 in the same bumper 1 to which the sensor is mounted, as shown in FIG. 3, in order to improve the storage property.

However, when installing such an electronic circuit unit 2 into the bumper 1 of a car, if the bumper itself is made of shock-absorbing urethane foam or the like and is relatively easily deformed by external force, the electronic circuit unit 2 is attached to the sub-circuit unit. 2 is fixedly attached to the bumper 1 side (or the vehicle body side), there is a high possibility that the bumper 1 will be dented and the electronic circuit unit 2 will be destroyed when it collides with an obstacle.

1 degree The present invention has been made in consideration of the above points.

When installing an electronic circuit unit inside a bumper made of urethane foam that is relatively easily deformed by external force, the electronic circuit unit must be installed so that the internal electronic circuit unit will not be destroyed even if the bumper is deformed by external force. The present invention provides a vehicle body mounting structure for an electronic circuit unit in which the circuit unit is mounted on the vehicle body (including a pumper).

In order to achieve the object of the present invention, the present invention provides a means for mounting the electronic circuit unit in the bumper with a mounting portion that allows the electronic circuit unit to fall off due to external force applied to the bumper in the event of a collision or the like.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the vehicle body mounting structure of the electronic circuit unit according to the present invention, as shown in FIG. 1(a), when installing the electronic circuit unit 2 in the bumper of the automobile, the base member 4 as appropriate using bolts 5, etc., and attach the electronic circuit nut 2.
A hook member 7 having a spring property that moves together with the base member 4 is integrally formed on the side of the frame 6 that holds the electronic circuit unit 2, and the electronic circuit unit 2 is mounted by engaging the hook member 7 with the base member 4. I have to.

However, according to such a mounting structure of the electronic circuit unit 2, as shown in FIG. 2(b), the hook member 7 is detached from the base member 4 and held when an impact force F is applied from the direction shown in the figure. The electronic circuit unit 2 will fall off together with the frame 6.

Therefore, if the bumper 1 is made of urethane foam or the like and is relatively easily deformed by external force,
Even if the bumper 1 is dented by colliding with an obstacle, the electronic circuit unit 2 mounted inside the bumper 1 is prevented from falling off and being destroyed.

In addition, in the structure shown in FIG. 1, even if the hook member 7 does not have spring properties, the hook member 7 can be easily deformed by the impact force F and disengaged from the base member 4, such as synthetic resin. The same effect can be obtained even if it is made of the same material.

FIG. 2 shows another embodiment of the present invention. In this case, the electronic circuit unit 2 is directly attached or fixed to the bumper avenue 3 via the support member 8, and the The member 8 is made of synthetic resin, for example, and a portion a that is easily broken by an external force is formed in advance, so that when an impact force is applied to the bumper 1, the support member 8 is
It is designed so that the electronic circuit unit 2 is broken in some parts and falls off.

It goes without saying that when the electronic circuit unit 2 is mounted inside the bumper 1, it may be mounted on the body side instead of on the bumper face 3 side. Also, an electronic circuit unit 2 is installed inside the bumper 1.
When installing the electronic circuit unit 2, the bumper 1 is generally attached to the body side with mounting members at both ends. It is preferable to attach it to the center between the members.

As described above, in the vehicle body mounting structure of the electronic circuit unit according to the present invention, the electronic circuit unit is mounted in the bumper of the vehicle via a support member that is destroyed or deformed by external force, and when the external force is applied to the bumper, the electronic circuit unit is installed in the bumper of the vehicle. The circuit unit is designed to fall off, and has the excellent advantage of effectively preventing the electronic circuit unit installed inside from being destroyed even if the bumper is deformed by external force. are doing.
