2. Description of the Related Art Generally, a window regulator is provided in an interior of an automotive door to control the lifting and lowering of the glass and the opening and closing of the door. Particularly, the window regulator is composed of various parts such as a wire for lifting and lowering, and a mounting panel is used to easily install and assemble these parts.

Figure 1 shows a conventional mounting panel. The mounting panel 10, to which the accessories used in the interior of the vehicle door can be coupled, may be provided with a wire, a wire drum winding a wire, a pulley, a motor, and the like. In order to install such an accessory, the mounting panel 10 is provided with an X-shaped wire groove 20, a drum groove 30 in which a wire drum can be arranged, a pulley groove 40 in which a pulley can be arranged, A motor groove 50 that can be disposed, and the like are provided.

The mounting panel 10 must maintain a constant strength to support the accessory used inside the vehicle door. In order to maintain the strength of the mounting panel as described above, a conventional Korean Registered Utility Model No. 20-0374170 (published on Jan. 25, 2005) describes the reinforcing structure of the mounting panel. In the conventional mounting panel reinforcing structure, annular beads are provided outside the mounting to reinforce the rigidity of the mounting panel.

However, such a conventional mounting panel reinforcing structure has the following problems. Conventional mounting panel reinforcement structures provide a separate external component to reinforce the rigidity of the mounting panel, which increases the overall weight of the mounting panel. The increased weight of the mounting panel increases the weight of the vehicle door.

 In general, when parts and structures are joined to the mounting panel to reinforce the mounting panel, the stiffness is improved but the weight is increased. Conventionally, there is no structure that can reinforce the rigidity of the mounting panel while lightening the weight of the mounting panel. Thus, there is a problem that the rigidity can not be reinforced while lightening the mounting panel.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Referring to FIG. 2, the mounting panel 100 of the present invention includes a panel 110 and a fiber-reinforced plastic 120.

The panel unit 110 is a plate-like member to which an accessory used for an automobile door can be coupled. The panel unit 110 may be a wire, a wire drum, a motor, a speaker, or the like used for an automobile door. The panel unit 110 is provided with various grooves for connecting wires, a wire drum, a motor, and a speaker. Further, a protruding portion may be provided for coupling the wire, the wire drum, the motor, the speaker, or the like, and a portion to which the bolt is coupled may be provided. The accessories to be coupled to the panel unit 110 are not limited to the wire, the wire drum, the motor, and the speaker, and various accessories may be combined.

Referring to FIG. 3, a plurality of ribs 130 protruding from the panel unit 110 and extending in the longitudinal direction may be provided on a rear surface of the panel unit 110. Wherein a front surface of the panel unit 110 is a surface to which the fiber reinforced plastic 110 is attached and a rear surface of the panel unit 110 is an opposite surface to which the fiber reinforced plastic 110 is attached. The ribs 130 are provided to compensate the bending strength of the panel unit 110. Although the fiber-reinforced plastic 120 to be described later is strong against tensile strength, if the fiber-reinforced plastic 120 is weakly warped and has a certain warpage, the fiber-reinforced plastic 120 may be broken.

The ribs 130 are provided to complement the bending strength of the mounting panel 100 and may extend in the horizontal and vertical directions. That is, the ribs 130 are formed in a lattice shape extending in the horizontal direction and the vertical direction, so that even if the mounting panel 100 is bent in various directions, the ribs 130 can be supplemented. It should be understood that the extending direction of the rib 130 is not limited to the horizontal direction and the vertical direction but may extend in various directions. For example, the ribs 130 may extend diagonally.

Referring to FIGS. 2 and 4, the panel unit 110 may have a protrusion 111. The protruding portion 111 penetrates the fiber reinforced plastic 120 rather than being covered with the fiber reinforced plastic 120 to be described later attached to the panel portion 110. The protrusion 111 is provided for an accessory to be coupled to the panel unit 110 and can be used for various purposes. For example, the protrusion 111 may be a wire protrusion 111a for connecting a wire or a rail protrusion 111b for slidably moving a carrier plate for operating an automobile door window.

Although the protrusion 111 is used for engaging the automotive door fittings, the adhesion force between the panel part 110 and the fiber reinforced plastic 120 can be increased through the protrusion 111. In the manufacturing method of the mounting panel 100 to be described later, the fiber-reinforced plastic 120 is provided in the mold, and the panel 110 is manufactured by dissolving the material of the panel 110 and injecting inserts . At this time, the material of the melted panel unit 110 is cured, and the fiber-reinforced plastic 120 is attached to the panel unit 110. The portion of the fiber-reinforced plastic 120 corresponding to the protrusion 111 is provided with a groove or cut, and the contact area between the panel portion 110 and the fiber-reinforced plastic 120 is wide, The adhesive strength between the panel part 110 and the fiber-reinforced plastic 120 is improved. (That is, the fiber-reinforced plastic 120 adheres to the surface around the protrusion 111, thereby improving the adhesion).

The panel unit 110 may be made of polypropylene resin (PP) or polyamide resin (PA). When the panel unit 110 is made of polypropylene resin, 20% to 50% of long fiber thermoplastic (LFT) may be included. Further, even when the panel unit 110 is made of a polyamide resin, 20% to 50% of LFT (Long Fiber Thermoplastic) may be included. The long fiber thermoplastic (LFT) serves to increase the strength and rigidity of the panel unit 110, thereby reducing the weight of the panel unit 110. The material of the panel unit 110 may be PA6 and PA66, and PA6 and PA66 are known materials, and a detailed description thereof will be omitted.

However, it is needless to say that the material of the panel unit 110 is not limited thereto, and various materials can be used. For example, the material of the panel 110 may vary depending on the fiber-reinforced plastic 120, and a material having high adhesion to the fiber-reinforced plastic 120 may be used.

The fiber reinforced plastic 120 is attached to the panel unit 110 and is formed by stacking a plurality of fiber sheets 121 including fibers 122 extending in one direction. The fiber sheet 121 is made of a material resistant to tensile and having a directional fiber 122.

Referring to FIG. 6, the extending directions of the fibers 122 of the plurality of fibrous sheets 121 cross each other. The fiber sheet 121 is strong against tensile in the direction in which the fibers 122 extend, but may not be strong against tensile in the other direction. In order to compensate for this, the fiber sheets 121 are overlapped with each other in the direction in which the fibers 122 extend.

That is, if three fiber sheets 121 are provided, the direction of extension of the fibers 122 of the first fiber sheet 121 is transversely oriented, and the fibers 122 of the second fiber sheet 121 are oriented horizontally. The extension direction should be vertical. Then, the fiber reinforced plastic 120 is formed by overlapping the third fiber sheet 121 with the fibers 122 extending in the lateral direction. Here, the number of the fiber sheets 121 to be stacked is not limited to three, and a plurality of the fiber sheets 121 may overlap each other.

As the fiber reinforced plastic 120 is formed by intersecting the extending directions of the fibers 122 of the plurality of the fiber sheets 121, the fiber reinforced plastic 120 is strong in tensile strength in various directions. The fiber reinforced plastic 120 may be made of various materials such as glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastics (CFRP), aramid fiber reinforced plastics (AFRP), DFRP fiber Reinforced Plastics), Zylon fiber Reinforced Plastics (ZFRP), and BFRP (Boron fiber Reinforced Plastics). However, the material of the fiber-reinforced plastic 120 is not limited thereto, and various materials may be used. The material of the panel 110 and the fiber-reinforced plastic 120 may be selected according to the adhesion between the panel 110 and the fiber-reinforced plastic 120.

The manufacturing method of the mounting panel with the fiber-reinforced plastic according to the present invention will be described in detail as follows. The configuration used in the manufacturing method of the mounting panel is the same as the above-mentioned configuration, and a detailed description of each configuration will be omitted.

Referring to FIG. 5, a manufacturing method of a mounting panel with a fiber-reinforced plastic according to the present invention includes a fiber sheet cutting step S100, a fiber sheet placing step S200, a fiber reinforced plastic making step S300, (Step S400).

The fiber sheet cutting step S100 may be performed by attaching the accessories used in the automotive door to the fiber sheet 121 including the fiber 122 extending in one direction according to the shape of the panel part 110, ). The panel unit 110 is provided with various grooves and protrusions 111 to which the automotive door fittings can be coupled, and the fiber sheet 121 is cut in consideration of such a shape. The fiber reinforced plastic 120 is formed by stacking a plurality of fiber sheets 121. In the fiber sheet cutting step S100, a plurality of fiber sheets 121 are cut.

Referring to FIG. 6, the fiber sheet placing step S200 is a step of disposing a plurality of fiber sheets 121 cut in the fiber sheet cutting step S100 so that the fibers 122 are crossed with each other. The fiber sheet 121 is strong in tension in the direction in which the fibers 122 extend, but may not be strong in tension in the other direction. In order to solve this problem, the fiber reinforced plastic 120 is fabricated by stacking the fiber sheets 121 while crossing the extending direction of the fibers 122 of each of the fiber sheets 121. The fiber sheet placing step (S200) is a step of arranging the plurality of fiber sheets 121 so that the fibers 122 are crossed with each other.

That is, if three fiber sheets 121 are provided, the direction of extension of the fibers 122 of the first fiber sheet 121 is transversely oriented, and the extension direction of the fibers 122 of the second fiber sheet 121 is lengthwise Lt; / RTI > And the fibers 122 of the third fiber sheet 121 are laterally oriented. Here, the number of the fiber sheets 121 to be stacked is not limited to three, and a plurality of the fiber sheets 121 may overlap each other. (In the fiber sheet cutting step S100, a plurality of fiber sheets 121 are cut in consideration of the extending direction of the fibers 122 so that the fibers 122 are arranged so as to intersect each other.)

The fiber-reinforced plastic manufacturing step S300 is a step of fabricating the fiber-reinforced plastic 120 by overlapping and processing a plurality of fiber sheets 121. A plurality of fiber sheets 121 are stacked and compressed while hot to form a plurality of fiber sheets 121 as a single fiber reinforced plastic 120. Since the fiber sheet 121 is made of the same material, when the fiber sheet 121 is compressed while being heated, the plurality of fiber sheets 121 can be melted and joined together. The method of fabricating the plurality of fiber sheets 121 in the fiber-reinforced plastic fabricating step S300 is not limited to the method described above, and a plurality of fiber sheets 121 may be combined to form a single fiber- Various processing methods can of course be used.

The panel attaching step S400 is a step of attaching the fiber reinforced plastic 120, which is formed by stacking a plurality of fiber sheets 121, to the panel part 110. [ The fiber-reinforced plastic 120 may be attached to the panel part 110 through an insert injection. A fiber reinforced plastic (120) is provided on a mold for insert injection, and the panel part (110) is manufactured by dissolving the material of the panel part (110) and injecting insert. At this time, as the material of the melted panel unit 110 is cured, the fiber reinforced plastic 120 is attached to the panel unit 110.

The protrusion 111 may be formed on the panel 110 so that the protrusion 111 penetrates the fiber reinforced plastic 120 rather than being covered with the fiber reinforced plastic 120 attached to the panel 110 It is. That is, the fiber-reinforced plastic 120 is formed with a cut groove 123 corresponding to the protrusion 111 so that the protrusion 111 can come out.

For example, the protrusion 111 may be a wire protrusion 111a for making a wire, or a rail protrusion 111b for slidingly moving the carrier plate. At this time, the fiber-reinforced plastic 120 may also be provided with a cut groove 123 corresponding to the protrusion 111 so that the protrusion 111 may come out. (See FIG. 6, a wire cut groove 123a corresponding to the wire protrusion 111a and a rail cut groove 123b corresponding to the rail protrusion 111b) may be provided.

The material of the melted panel part 110 can be moved through the cut grooves 123 and the contact area between the fiber reinforced plastic 120 and the panel part 110 is widened to improve the adhesion. That is, the panel unit 110 can increase the contact force between the fiber-reinforced plastic 120 and the panel unit 110 by increasing the contact area between the fiber-reinforced plastic 120 and the panel unit 110 through the cut- .

The material of the panel unit 110 may be a polypropylene resin or a polyamide resin and the material of the fiber reinforced plastic 120 may be glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastics (CFRP) , Aramid fiber Reinforced Plastics (AFRP), Dyneema fiber Reinforced Plastics (DFRP), Zylon fiber Reinforced Plastics (ZFRP), and Boron fiber Reinforced Plastics (BFRP). The panel 110 and the fiber-reinforced plastic 120 may be made of a material that improves the adhesion between the panel 110 and the fiber-reinforced plastic 120 when the insert is injected, taking into account the respective physical properties.

The panel 130 may be provided with a rib 130 to compensate for insufficient bending strength of the mounting panel 100. The rib 130 may be formed on the surface of the panel 110, And protrudes from the panel part 110 on the rear surface of the housing 110 and extends in the longitudinal direction. As described above, the rib 130 is not described in detail.
