Abstract
A frame structure of a vehicle includes: a first member composed of a metal plate, and a second member composed of a metal plate having a thickness thinner than that of the first member, the second member integrally connected to the first member by welding. The connection portion between the first member and the second member has an inclined surface configured to obliquely connect an upper surface of the first member and an upper surface of the second member such that the upper surface of the second member is positioned to be lowered than the upper surface of the first member in a gradual manner.
Claims18
A frame structure of a vehicle comprising:
- a first member composed of a metal plate;
- and
- a second member composed of a metal plate having a thickness thinner than that of the first member, the second member integrally connected to the first member by welding,
- wherein a connection portion between the first member and the second member has an inclined surface, which is configured to obliquely connect an upper surface of the first member and an upper surface of the second member such that the upper surface of the second member is positioned to be lowered than the upper surface of the first member in a gradual manner,
- wherein the first member and the second member have bottom surfaces, respectively, leveled to each other,
- wherein the frame structure further includes a panel member configured to be attached to the bottom surface of the first member and the bottom surface of the second member, and
- wherein the panel member and the connection portion are spaced apart from each other and the first member and the second member are spaced apart from each other, such that a paint is disposed in a space between the first member, the second member, and the panel member.
A frame structure of a vehicle comprising:
- a first member composed of a metal plate;
- a second member composed of a metal plate having a thickness thinner than that of the first member, the second member integrally connected to the first member by welding;
- and
- a glass run disposed in a portion in which the first member and the second member are connected in a stepwise manner,
- wherein the first member and the second member have bottom surfaces, respectively, leveled to each other, and
- wherein the frame structure further includes a panel member configured to be attached to the bottom surface of the first member and the bottom surface of the second member.
A method of manufacturing a frame structure of a vehicle, the method comprising:
- forming a first member composed of a metal plate;
- and
- forming a second member composed of a metal plate having a thickness thinner than that of the first member, the second member integrally connected to the first member by welding,
- wherein a connection portion between the first member and the second member has an inclined surface, which is configured to obliquely connect an upper surface of the first member and an upper surface of the second member such that the upper surface of the second member is positioned to be lowered than the upper surface of the first member in a gradual manner, and
- wherein the inclined surface is configured to be integrally connected with the upper surface of the first member and the upper surface of the second member in a way that the upper surface of the first member is higher than the upper surface of the second member,
- wherein the connection portion is integrally attached to an end of the first member contacting an end of the second member.
