Abstract
An impact absorption unit provided between an inside member and an outside member that form a vehicle body and configured to absorb an impact may include: a first absorption body which includes composite material and protrudes from an inside surface of the inside member toward the outer member, with an open receiving space formed in the first absorption body; and a second absorption body which includes composite material and protrudes from an inside surface of the outside member toward the inside member such that the second absorption body is inserted into the open receiving space.
Claims15
An impact absorption unit provided between an inside member and an outside member that form a vehicle body and configured to absorb an impact, the impact absorption unit comprising:
- a first absorption body including composite material and protruding from an inside surface of the inside member toward the outer member, with an open receiving space formed in the first absorption body;
- and
- a second absorption body including composite material and protruding from an inside surface of the outside member toward the inside member such that the second absorption body is inserted into the open receiving space.
A manufacturing method of an impact absorption unit provided between an inside member and an outside member that form a vehicle body and configured to absorb an impact, the manufacturing method comprising:
- forming a first absorption body using reinforced fiber and resin, the first absorption body having a receiving space that is open on a first side thereof, and of coupling a second side of the first absorption body to an inside surface of the inner member;
- forming a second absorption body using reinforced fiber and resin, the second absorption body having a protruding shape;
- coupling the second absorption body to an inside surface of the outer member;
- and
- assembling the inside member with the outside member such that the second absorption body is inserted into the open receiving space of the first absorption body.
An impact absorption reinforcement provided between an inside member and an outside member that form a vehicle body and configured to absorb an impact, the impact absorption reinforcement comprising:
- a plurality of impact absorption units,
- wherein each of the impact absorption units includes:
- a first absorption body including composite material and protruding from an inside surface of the inside member forming the vehicle body toward the outer member, with an open receiving space formed in the first absorption body;
- and a second absorption body including composite material and protruding from an inside surface of the outside member toward the inside member such that the second absorption body is inserted into the open receiving space, and
- wherein the impact absorption units are positioned such that each pair of the impact absorption units are symmetrical with each other based on one central impact absorption unit.
