Description

Rigid reinforcement structure for vehicle fenders {Sructure for reinforcing fender's stiffness in vehicle}

The present invention relates to a rigid reinforcement structure of a vehicle fender, and more particularly, to a rigid reinforcement structure of a vehicle fender to increase the rigidity of the fender by laying a reinforcement bracket between the body panel and the fender.

The fender is mounted on the outside of the vehicle body panel, and is located at the upper side of the tire on both sides of the vehicle body, and is manufactured in various forms according to the vehicle model.

The fender is generally mounted by bolting to a vehicle body panel, but as shown in FIG. 1, a space having a “Δ (delta)” shape is formed between the A-pillar of the vehicle and the front door glass, and thus the delta glass ( In case of delta glass type vehicles equipped with plastic molding, there is a problem in the mounting and rigidity reinforcement of the fender due to the layout problem inside the vehicle, and it is not easy to install a separate reinforcement on the fender and the body panel. .

Therefore, the conventional fender rigid reinforcement structure to solve this, additionally forms a flange of the bent shape on the top of the fender and the delta glass is assembled to press the support to the flange, or between the body panel and the fender under the delta glass The "L" shaped bracket was inserted into the body panel and the fender was fixed by screws.

However, the flange-based method could cause a step difference due to the tolerance of the assembly of the delta glass, and the "L" shaped bracket required an additional assembly step for screw mounting and the delta to remove the upper screw when replacing the fender. Removal of the glass was required, which could increase the after-sales cost.

Therefore, the present invention has been invented to solve the above problems, and the main object of the present invention is to provide a rigid reinforcement structure of a vehicle fender which increases rigidity of the fender and improves assembly.

The present invention for achieving the above object, in the rigid reinforcement structure of the vehicle fender for increasing the rigidity of the fender is coupled to the outside of the body panel, bent to form the coupling portion, the support portion and the connecting portion as a plate (板) shape The coupling part and the support part face each other, and the connection part includes a reinforcing bracket bent to extend to the coupling part and the support part, respectively, and the reinforcing bracket has an elastic pad attached to the support part between the body panel and the fender. Is mounted on, the coupling portion is bonded to the body panel, characterized in that the pad is mounted so as to face the fender.

The pad is made of an expanded plastic material that expands when heated, and is disposed to have a predetermined gap with the fender, and the pad is heated to close the fender so that the gap is eliminated.

The coupling part is bonded to the vehicle panel by spot welding using a welding gun, and a support hole is formed in the support part to allow the welding gun to enter and exit, and two pads are disposed side by side with the passing hole interposed therebetween. do.

In addition, a reinforcing groove is formed to cross the coupling part, the support part, and the connecting part to improve the bending rigidity of the reinforcing bracket.

In addition, the vehicle body panel (in a position where the fender is not coupled) is formed with a partially protruding protrusion, and one side of the coupling portion is formed with a bending portion having a hole formed to be bolted to the protrusion.

The present invention having the above configuration has the effect of further increasing the rigidity of the fender even in the delta glass type vehicle in which the mounting of the fender is restricted due to the layout of the vehicle (as well as the general vehicle).

In addition, the pad of the present invention may be in close contact with the fender naturally through a coating process in which heat is applied to the vehicle body after installation of the fender as a foamed plastic material that expands when heated.

Figure 4 is a cross-sectional view AA of Figure 2 is a state in which the reinforcing bracket is mounted between the body panel and the fender according to the present invention.

Hereinafter, with reference to the drawings will be described in more detail the rigid reinforcing structure of the vehicle fender according to the preferred embodiment of the present invention.

The present invention is characterized in that the reinforcing bracket 10 is mounted between the fender 20 and the body panel 30 to increase the rigidity of the fender 20 coupled to the outside of the body panel 30.

Referring to FIG. 2, the reinforcing bracket 10 has a plate shape bent in a "c" shape, and each of the reinforcing brackets is bent to form a coupling part 10c, a support part 10a, and a connection part 10b. do.

The coupling part 10c and the support part 10a are spaced apart from each other so as to be in contact with the body panel 30 and the fender 20, respectively, and the connection part 10b is the coupling part 10c and the support part 10a. Both sides are extended to the coupling part 10c and the support part 10a so as to space apart.

In addition, the support part 10a is attached with a pad 11 made of a foamed engineering plastic that expands in volume when heated to a predetermined temperature or more. The pad 11 is manufactured to have a rectangular shape and two are arranged in parallel, and a passing hole 12 is formed in the support part 10a therebetween. The passing hole 12 is formed to have a size that allows the welding gun used to spot weld the coupling part 10c to the vehicle body panel 30.

In addition, the mounting portion 13 is bent to one side of the coupling portion (10c). The mounting portion 13 is formed with a hole 14 to be bolted to the protruding portion of the body panel 30. That is, the mounting portion 14 is bent to be bolted and fixed to the protruding portion of the vehicle body panel or other panels mounted on the vehicle body panel.

The reinforcing bracket 10 is formed with a reinforcing groove 15 formed to cross the coupling part 10c, the supporting part 10a, and the connecting part 10b so as to increase bending rigidity.

As shown in FIG. 3, the reinforcement bracket 10 configured as described above is attached to the vehicle body panel on which the fender is mounted by spot welding using a welding gun. In this case, as described above, since the support gun 10 has a passing hole 12 through which the welding gun can enter and exit, welding is possible up to the upper side of the reinforcing bracket 10.

When the reinforcing bracket 10 is attached to the vehicle body panel 30, the fender 20 is mounted to the outside as shown in FIG. 4. The fender 20 is bolted at each point in a conventional conventional manner. In this case, the fender 20 may be mounted to be in close contact with the pad 11 adhered to the support 10a, but is preferably disposed to have a predetermined gap in consideration of the expansion of the pad 11.

The fender 20 assembled as described above is in close contact with the supporting portion 10a by being heated and expanded while the pad 11 is heated through a painting process that is performed later in the production process of the vehicle. Alternatively, the fender 20 may be in close contact with the support part 10a and the fender 20 by locally applying heat to a portion where the pad 11 is located after the fender 20 is replaced. .

As described above, the embodiments disclosed in the specification and the drawings are only presented as specific examples to aid the understanding of the present invention, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
