The antenna module 4 is mounted using the fixing bolt 5, and the square nut 6 which is fastened to the fixing bolt 5 is welded on the inner side.

The existing square nut fixing structure as described above should have welding equipment to fix the square nut fastened to the fixing bolts on the body panel by welding, and in order to perform the welding work, the working space for the welding equipment should be sufficient. Additional costs for the welding work are also required.

In addition, since the operator must directly carry out the welding operation to which the square nut is attached, the welding of the square nut to the body panel of excessive size or heavy weight may cause a safety accident. Have.

An object of the present invention devised to solve the problems as described above is to easily fix the square nut fastened to the fixing bolt during the bolting operation to the vehicle body panel without using an additional process without welding.

In order to achieve the object of the present invention as described above, in the bolting operation, folding the seat panel as large as the size of the square nut fastened to the fixing bolt in two stages to establish a support so that the square nut does not rotate or escape from the inside thereof and again. Provided is a nut fixing bracket structure formed to be fixed to a desired panel position.

Hereinafter, a nut fixing bracket structure according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4a is a perspective view showing a nut fixing bracket according to an embodiment of the present invention, Figure 4b is a view showing a cross-sectional view of the BB portion in Figure 4a, Figure 5 is a development showing a state in which the nut fixing bracket is unfolded Perspective view.

As shown in the figure, the nut fixing bracket 120 for attaching the square nut 110 fastened to the fixing bolt during the bolting operation on the body panel 100 is formed in a size similar to the size of the square nut 110. The first, second and third seating panels 122, 124 and 126 are formed by being folded in multiple stages, and the first, second and third seating panels 122, 124 and 126 are molded into a square flat plate. In the center, a bolt insertion hole 128 is formed in which a fixing bolt is inserted, and is connected by a connection panel 140 each formed in a rectangular shape.

The first seat panel 122, which forms a lower surface when the nut fixing bracket 120 is multi-stage bent due to the square nut 110 positioned at the center thereof, is formed to prevent the square nut 110 from being detached at one end thereof. 1 The guide part 130 is formed.

The second seat panel 124 which is connected to the other side of the first seat panel 122 and forms the intermediate surface when the nut fixing bracket 110 is bent in multiple stages is separated from the square nut 110 at the upper and lower ends thereof. The second and third guide parts 132 and 134 are formed to prevent the same.

The third left side panel 126, which is connected to the other side of the second left side panel 124 and forms the upper surface at the time of multi-stage bending, has the other end at a predetermined angle so as to prevent separation when the nut fixing bracket 120 is fixed. It is shape | molded by ((alpha)).

The nut fixing bracket structure according to the embodiment of the present invention having the above configuration includes a square nut 110 fastened to the fixing bolt 150 between the first left side panel 122 and the second left side panel 124. In the mounted state, the third seat panel 126 is inserted into the bracket fixing hole 160 formed on the vehicle body panel 100 to be fixed to the vehicle body panel 100.

FIG. 6 is a cross-sectional view of a quarter panel to which a nut fixing bracket is applied according to an embodiment of the present invention. As shown in the drawing, the inside of the side outer panel 10 formed at the rear of the vehicle body 1 is illustrated. Quarter inner panel 20 is bonded by welding, the antenna module 30 is mounted on the outer surface of the quarter inner panel 20 using a fixing bolt 150, the inner surface on the The square nut 110 which is fastened to the fixing bolt 150 is joined using the nut fixing bracket 120.

A bracket fixing hole 160 into which the third seat panel of the nut fixing bracket 120 is inserted is formed on the quarter inner panel 20 together with a bolt hole into which the fixing bolt 150 is inserted.

The present invention having the above configuration can be easily operated at a desired time at a desired position in the design process during the vehicle assembly process, and the time for welding the square nut in the state in which the operator holds the vehicle panel by hand can be omitted. When the square nut is assembled on a large sized body panel, the process of welding the square nut on a separate panel and re-welding it can be omitted, thus reducing the production cost of the vehicle. It has the effect of reducing the risk of safety accidents by reducing the risk of welding.
