Definitions

  • This invention relates to a seat cushion panel of a vehicle manufactured using a magnesium alloy and a method of manufacturing the same.
  • seat frames have been manufactured using light-weight materials instead of more traditional steels. More specifically, the seat frames made of a magnesium alloy by means of a high pressure casting method are advantageous in that repeated mass production is possible. These seats also make it possible to significantly reduce noise levels through dimensional accuracy.
  • seat cushion panels are installed on the top of a base they barely affect the safety evaluations of these seats. Further, being of a rather simple shape, the seat cushion panels can be manufactured using steel materials by means of a press and then connected to other auxiliary parts by welding.
  • This invention provides a reinforcing means of a round shape which is applicable only to a high pressure casting process in molding a seat cushion panel adapted to replace the notched part present in a conventional press molding, where stress is concentrated, thereby improving the quality of products.
  • This invention further provides a switch bracket, which is employed in a motor-driven seat, with a clip-inserting structure for its installation instead of a conventional welding method, thereby reducing the number of steps in a molding process required for manufacturing a seat cushion panel of a vehicle.
  • This invention further provides a magnesium alloy seat cushion panel of a vehicle wherein the area for installing S spring is designed in a supportive structure where both ends are closed unlike the conventional ones where one end is open, thereby increasing the fatigue endurance strength.
  • This invention further provides a method for manufacturing a magnesium alloy seat cushion panel of a vehicle, wherein a casting gate is provided in the center of a mold so that the molten metal can be dispersed at various directions to be flowed into a mold at the time of a casting via a die casting process to enable a high pressure casting.
  • FIG. 1 is a perspective view of a part of the seat cushion panel of a vehicle made of a magnesium alloy according to an embodiment of the present invention, wherein the notched part in the conventional steel press product is replaced with a round shape;
  • FIG. 2 is a perspective view of a part of the seat cushion panel of a vehicle made of a magnesium alloy according to an embodiment of the present invention, wherein an area for installing the conventional S spring with one open end is replaced with one with both ends closed;
  • FIG. 3 is a perspective view of a clip-inserting structure of a switch bracket of a seat cushion panel of a vehicle made of a magnesium alloy according to an embodiment of the present invention.
  • FIG. 4 shows perspective views for the flow of molten metal over time and the location of a gate installation at the time of casting a seat cushion panel of a vehicle made of a magnesium alloy, according to an embodiment of the present invention.
  • This invention relates to a seat cushion panel of a vehicle manufactured using a magnesium alloy and a method of manufacturing the same. More particularly, this invention relates to a seat cushion panel of a vehicle manufactured using a magnesium alloy and a method for manufacturing the same, wherein the properties of a magnesium alloy used for manufacturing the conventional steel press seat cushion panels are particularly reinforced while its advantageous properties such as light-weight and easy castability are much improved.
  • a reinforcing means in a certain part of the housing panel 10 to overcome the problem of concentrated stress being loaded on a certain portion of the housing panel 10 that is known to be vulnerable to the concentrated stress.
  • the above reinforcing means includes a reinforcing means 11 having a round shape mounted on the curved portion of the housing panel while a spring mounting element having a supportive structure with both ends closed is formed on the area where the S spring is to be mounted.
  • a clip-inserting structure in the housing panel 10 so that a switch bracket 13 ( FIG. 3 ), which is employed in a motor-driven seat, can be readily fixed.
  • a casting gate 20 ( FIG. 4 ) installed in the center of a mold so that a molten metal can be dispersed in various directions and flow through the casting gate 20 at the time of molding via a die casting process.
  • the molten metal is introduced at the rate of 4.0-5.0 m/sec under the virtual pressure of 600 bar, wherein the sleeve is formed to have a diameter of 100 mm.
  • FIG. 1 shows a part of the seat cushion panel of a vehicle made of a magnesium alloy according to an embodiment of the present invention, wherein the notched part present in the conventional steel press product is converted to be round in shape.
  • FIG. 2 shows a part of the seat cushion panel of a vehicle made of a magnesium alloy according to an embodiment of the present invention, wherein an area for installing the conventional S spring with one open end is replaced with that having both ends closed.
  • FIG. 3 shows a clip-inserting structure of a switch bracket in the seat cushion panel of a vehicle made of a magnesium alloy according to an embodiment of the present invention.
  • this invention relates to a magnesium alloy seat cushion panel of a vehicle wherein a conventional steel seat cushion panel prepared by pressing is replaced with a magnesium alloy prepared by a high pressure casting process.
  • This rectifies mechanical properties while accompanying the conversion of its shape, and adds a rectifying means and improvement in the location of a casting gate.
  • the physical properties of the magnesium alloy used in manufacturing the seat cushion panel of a vehicle of the present invention are greatly reinforced, in particular with respect to its mechanical strength, by means of changing the shape, adding a new reinforcing means and improving the location of installing a casting gate, while maintaining the superior intrinsic properties of the magnesium alloy having a light-weight.
  • the seat cushion panel of this invention is designed to use all the parts prepared and used in a conventional pressing method for manufacturing the same.
  • a change in shape of a mold 15 for manufacturing the seat cushion panel of a vehicle so that the equal strength can be maintained in the seat cushion panel manufactured using the magnesium alloy of this invention as to that of the conventional steel made seat cushion panel. That is, a notched part, the particular part of the conventional seat cushion panel which is relatively vulnerable to concentrated stress, is replaced in this invention with a reinforcing means having a round shape.
  • the spring mounting part 12 ( FIG. 2 ), where the S spring is to be mounted, is designed with a supportive structure where both ends are closed unlike the conventional supportive structure where one end is open. Therefore, the seat cushion panel of a vehicle manufactured using a magnesium alloy according to this invention can achieve equally powerful physical properties as those manufactured using the conventional steel material while still maintaining the advantage of having light weight. Meanwhile, the step of forming a seat cushion of a vehicle is the most critical step to reflect a given design at its optimum level. In particular, the optimization of a casting process is one of the essential steps of this invention. In forming a seat cushion panel using a magnesium alloy, a solidification process can be performed rapidly under the optimized condition of a casting gate. Therefore, the casting should be performed using a high speed die casting process, and accordingly, it is essential to select a most appropriate location for installing a casting gate via rheological analysis.
  • FIG. 4 shows the flow of molten metal over time and the location of a gate installation at the time of casting a seat cushion panel of a vehicle made of a magnesium alloy, according to an embodiment of the present invention.
  • molten metal flows into a nearby area to uniformly fill-in the area.
  • the molten metal disperses in various directions, thereby firstly filling in the very end of the mold instead of being united in the middle. This reduces occurrences of casting defects.
  • the insertion time of the molten metal into a mold is significantly reduced as compared to that of a conventional insertion time, and is thus suitable for using a magnesium alloy material which solidifies rapidly.
