Description

Clips for Automotive Grommet Holes

The present invention is that the vibration noise is introduced into the interior of the car through the grommet hole that is left in the vehicle body after the assembly process of the grommet hole formed in a plurality of parts for mounting or locating various parts and devices on the vehicle body panel The present invention relates to a clip for a car grommet hole that can be effectively prevented. In particular, a hole penetrating the center is provided, a radial reinforcing part is provided at the upper part, and a circular flange part is provided at the lower part of the body of the through hole. An insert member is formed in the portion and a locking protrusion is formed to penetrate the grommet hole, and is inserted into and coupled to the through hole of the insert member, and at the same time, a stop protrusion is provided at the lower end of the body portion, and a flat head is provided at the upper portion thereof. Mounting member having a reinforcing rib made of a flexible material under the head A flange bottom portion of the insert member is interviewed and fixed to an upper surface of the stopper protrusion formed on the body portion of the mounting member, and a reinforcing rib of the mounting member is coupled to the upper surface of the flange portion of the insert member to bend. A reinforcement part of an insert member and a head part of a mounting member and a packing for a vehicle grommet hole clip are covered.

In general, the body is installed on the frame or directly connected to the suspension system to accommodate people or cargo, and is separate from the frame and integral with the frame. These bodies include the front body, the underbody and the side body. And the rear body, which is composed of first and second front pillars which form a support part of the front window including the engine compartment from the front fore end of the vehicle body. In order to alleviate the impact force in the room in the event of a frontal collision of the vehicle, the impact energy is sufficiently absorbed through proper stiffness adjustment in the front and rear directions. In addition, the engine and steering system are designed to minimize the amount of intrusion into the vehicle interior during a collision. When designing the engine room, inherent performance protection, workability, maintenance, It is considered and manufactured to properly block the inflow of noise into the car interior.

Since the underbody is directly mounted with a driving device such as a suspension device of an engine mounting transmission rear wheel driver, and is directly subjected to external force by this, the member has a structure reinforced with an element element. Unlike trucks, it has a three-dimensional structure without a frame, because the weight of the vehicle is lighter than that of the frame type, and because it is integrated with a body other than the frame, it can be designed with high rigidity. And high productivity. However, since the vibration of noise from the power transmission device is directly transmitted to the body, it is necessary to measure the soundproof soundproofing for this purpose, and for this purpose, it is manufactured considering the beads and members on the floor surface. In addition, when setting spare tire and fuel tank mounting positions on the trunk floor surface, it is designed and manufactured in consideration of energy absorption and fuel leakage prevention in the event of a collision.

The side body is a structural member forming a side portion of the vehicle, and serves to suppress deformation of the vehicle during vehicle overturning and side collision and to secure durability. The belt line top cross section of each pillar tends to be possible to widen the sieve, but the bending and torsional stiffness of the car body must be taken into account. The lower end portion of the belt line has a larger cross section compared to the upper portion, and many parts of the belt change rapidly, but are manufactured in consideration of the decrease in rigidity of the door because it supports the door. In addition, in the vicinity of the rear wheel of the side body, since the negative pressure of the outer surface is generally high during driving, a ventilation hole is provided in this area.

The rear body is located behind the passenger compartment, and is generally composed of the cargo compartment and the part including the side body and the part of the underbody. It is divided into a structure in which the side body of the body is attached, and a structure in which the cabin and the trunk room are not separated.

Self-panel and seat back supports contribute significantly to the torsional stiffness of the car body when the cabin and the trunk room are separated. However, vehicles that do not distinguish between the cabin and the trunk room do not have a self-panel and seat back support. Has a double structure or a fully closed cross section.

Finally, grommet holes having various sizes and shapes are formed through the bodies to pass through wire harnesses of electrical components or to mount various types of components and devices.

Conventionally, various kinds of devices and devices are installed by fixing various kinds of wire harnesses and weld nuts by welding operations as described above, and when the conventional grommet holes are used or not used, vibration noise of a vehicle, etc. To prevent this, various types of tape or extension nuts and clips are blocked.

However, since the grommet hole is formed to have different sizes, there is a problem of having a tape suitable for a grommet hole having various sizes and a problem of having extension nuts and clips having various diameters.

In addition, there is a problem that the work efficiency is deteriorated due to the delay of the work time and the difficulty of the work by providing a cover member according to various diameters and at the same time selecting the cover member according to the diameter to prevent the grommet hole.

The present invention is that the vibration noise is introduced into the interior of the car through the grommet hole that is left in the vehicle body after the assembly process of the grommet hole formed in a plurality of parts for mounting or locating various parts and devices on the vehicle body panel To provide a clip for a car grommet hole that can effectively prevent, as well as to simply and quickly block the grommet hole, the present invention is a circular body formed with a locking projection having an upper surface on the outer peripheral surface having a horizontal surface An insert member having a through-hole vertically formed in the center thereof, having a reinforcing portion formed horizontally to be divided in four directions on the upper portion of the body portion, and a flange portion having an annular groove portion formed on the lower portion of the body portion, and a horizontal plane The circular head part to be provided is formed in the upper portion, and at the same time having a concentric circle in the lower center The lower portion has a body portion is formed with a stop projection having a horizontal surface on the upper surface, and has a predetermined distance from the lower portion of the head is formed radially vertically downward and at the same time the end is horizontally inwardly bent to form a reinforcing rib It is composed of a mounting member, wherein the body portion and the flange portion of the insert member is installed through the grommet hole and the reinforcement portion is interviewed with the packing member to be interviewed around the upper surface of the grommet hole, the body portion of the mounting member is the insert The upper surface of the stopper protrusion is inserted into the through hole of the member and at the same time supports the bottom of the flange portion of the insert member, and the lower end of the reinforcing rib of the mounting member is engaged between the upper surface of the flange portion of the insert member and the stopping protrusion. When the parts are bent outwardly and joined, the bottom of the head is raised. Is interviewed to the reinforcing of the upper side is coupled.
