It relates to a high loop mounting structure.

In general, vehicles are classified into various types according to the purpose of use, the driving method, and the shape of the vehicle body. Recently, as leisure activities are rapidly increasing, the distribution of leisure vehicles (RV) is increasing accordingly.

Such leisure vehicles have a growing preference for vehicles having a high roof type that expands the ceiling space to maximize the space inside the vehicle to suit leisure activities. In the case of vans, in the case of van-type vehicles, a tax benefit is provided when the interior volume ratio in the cargo compartment is satisfied to a certain level, and in some countries, the volume ratio is regulated at all.

Therefore, if the vehicle structure is not changed in consideration of various factors of the exporting country, the obstacle of market expansion may occur and the vehicle sale itself becomes impossible.

At present, one of the things that can be considered to secure a sufficient indoor volume ratio is to change the ceiling of the vehicle to a high roof structure, in which the ceiling of the vehicle has a constant capacity rather than a smooth curved or flat plate roof panel. A container-shaped high loop with an inner space is applied.

In other words, by installing a container-shaped high loop having an internal space of a predetermined capacity in the form of an inverted portion of the ceiling of the vehicle body, the indoor height of the vehicle body is increased and a sufficient indoor volume ratio is secured.

And, Figure 3 is a rear view of the vehicle showing a state in which the high loop is separated to explain the mounting state of the high loop according to the present invention, Figure 4 is a rear view of the vehicle showing the assembled state of FIG.

As shown in the drawing, the vehicle 1 is formed with a cutout portion 3a having a shape in which a center portion of the upper panel, that is, the roof panel 3 is cut out, and a method of forming the cutout portion 3a is generally known. Detailed description is omitted since it is carried out by the technique.

As such, the cutout 3a formed in the roof panel 3 of the vehicle 1 is for communicating the interior of the vehicle interior with the interior of the high roof 10 when the high roof 10 is to be described later. The shape of the cutout 3a is formed in proportion to or smaller than the size of the opening side of the high loop 10. The cutout portion 3a is provided with a structure in which a weather strip 17 made of rubber or synthetic resin having excellent cushioning properties is fitted, and the weather strip 17 is known to be applied to a door or a trunk of a vehicle. It may be used.

Meanwhile, the high roof 10 is integrally coupled to the roof panel 3 of the vehicle 1, and the high loop 10 is made of synthetic resin or fiber reinforced plastics (FRP). It is molded, and its shape is a structure in which the close contact portion 10 'having a curvature having a corresponding lower curvature so as to be in close contact with the roof panel 3 of the vehicle 1 is integrally formed.

Here, as shown in the drawing, the close contact portion 10 ′ is formed with holes (not shown) that are spaced at equal intervals, and the through holes at this time are screw holes (not shown) formed in the roof panel 3. Is formed at the position corresponding to

The high loop 10 having such a configuration is attached in close contact with the roof panel 3 by the silicone curing agent 30 and the silicone layer 20 as adhesive means, and the screw member 40 to further strengthen the bonding force. Is the final mounting structure.

First, the adhesive means will be described. The roof panel 3 applies the silicone curing agent 30 to the edge of the cutout 3a to a predetermined thickness. At this time, the silicone curing agent 30 is a kind of material for taking a network structure by chemically bonding the molecules of the silicone compound to each other, which is used for gap generation and watertight between the joining members, and is mainly used as a sealant for a vehicle. It is possible to use Cicaprimer or Sikaflex. Here, Cica Primer or Cicaplex is made of polyurethane, and it is known to be excellent in strength when hardening, and to have excellent effect of absorbing vibration and blocking noise as well as absorbing strength. do.

Subsequently, a silicone resin is applied to the upper surface of the silicone curing agent 30 to a predetermined thickness to form the silicone layer 20. At this time, the silicon layer 20 plays a role of an adhesive that enables the close contact portion 10 ′ of the high loop 10 to be completely adhered to each other and ensures stable airtightness and water tightness. In addition, when the thickness of the silicon layer 20 is appropriately applied, vibration and impact force transmitted during vehicle driving are properly dispersed and reduced to prevent breakage due to impact while preventing the high loop 10 and the roof panel 3 from being separated from each other. Will be prevented.

Meanwhile, as shown in the drawing, one end of the rainwater guide 15 of the length member is interposed between the high loop 10 and the roof panel 3 to fix the position. Here, the rainwater guide 15 is provided in the form of a strip having a thin plate shape at one end and interposed between the high roof 10 and the roof panel 3, and the other end is outside the vehicle 1. As it protrudes, the end is bent upward to form a groove. By this configuration, rainwater flowing down the high roof 10 to the roof panel 3 in the rain flows along the groove of the rainwater guide 15.

As such, the high roof 10 and the roof panel 3 having the rainwater guide 15 interposed therebetween are the roof panel 3 of the vehicle 1 by the silicon curing agent 30 and the silicon layer 20, which are the above-described adhesive means. It is a structure that is mounted by a plurality of screw members 40 in a state attached to).

That is, when the high loop 10 is attached to the roof panel 3, in the state where the through holes of the high loop 10 and the screw holes of the roof panel 3 are positioned to coincide with each other, these holes form bolts. By screwing the screw member 40 having the high loop 10 and the coupling of the roof panel 3 can be more firmly increased.

The screw member 40 is preferably provided to be fastened at a plurality of points at equal intervals in order to ensure a stable coupling between the high loop 10 and the roof panel (3), if necessary washer ( w) or nuts may be used.

Briefly described the mounting method of the high loop of the vehicle configured as described above are as follows.

First, a part of the upper surface of the vehicle 1 to be constructed, that is, the roof panel 3 is cut out to form the cutout 3a. At this time, the shape of the cutout 3a preferably matches the shape of the opening of the high loop 10 to be mounted.

Subsequently, the silicone curing agent 30 and the silicon layer 20 are uniformly applied to the vehicle body surface corresponding to the edge of the cutout portion 3a, and then the close contact portion 10 'of the high loop 10 is bonded. Let's do it.

At this time, when attaching the high loop 10 to the roof panel 3 side, the through hole formed in the high loop 10 and the screw hole formed in the roof panel 3 side must coincide.

Meanwhile, when the high loop 10 is attached to the roof panel 3, one end of the rainwater guide 15 is inserted and fixed.

Subsequently, in the state where the high loop 10 and the roof panel 3 are joined as described above, the screw member 40 having a bolt shape is formed into the through hole of the high loop 10 and the screw hole of the roof panel 3. By inserting and fastening, the mounting of the high loop 10 described above is completed.

The high loop 10 mounted by such a process is adhered by the silicone curing agent 30 and the silicon layer 20, which are adhesive means, in a state of being completely in contact with each other without a gap, thereby ensuring stable watertightness and vibration generated while driving. In addition, since the shock is properly absorbed and reduced, the high loop 10 can be prevented from being separated or flowed.

Particularly, as the mechanical coupling is performed by the plurality of screw members 40 in the state in which the high loop 10 is bonded by the adhesive means as described above, it is possible to increase the reliability due to the improvement of the bonding property.

On the other hand, the present invention is not limited to the described embodiments, it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.

The high loop mounting structure of the vehicle constructed and operated as described above is firmly coupled using a plurality of screw members in a state in which the high loop is bonded to the roof panel using a silicone hardener and a silicone layer having excellent water tightness and cushioning properties. Since it is possible to prevent the risk of high loop flow and breakage caused by vibration or shock generated while driving, there is an advantage that can improve the reliability of the product by ensuring the running stability.
