Abstract
It is an object of the present invention to prevent a vehicle door from protruding into a vehicle cabin when a collision load is applied to the door from a lateral side thereof, and to reduce costs that are required for measures to prevent the door from protruding into the vehicle cabin.
Claims3
A vehicle body structure in which a collision load applied to one of vehicle doors from a lateral side thereof is received by a load receiving member of a body via an impact beam and a door box of the door and is transmitted from the load receiving member to a cross member, the load receiving member comprising:
- a load receiving pipe that is formed as a linear tubular body disposed between the right and left doors so as to extend in a vehicle widthwise direction and is capable of transmitting the collision load from the door box of one of the doors to a door box of the other of the doors;
- and
- connecting portions that are capable of supporting the load receiving pipe at positions adjacent to the right and left doors and connecting the load receiving pipe to the cross member,
- wherein the door box has a receiving surface to which the impact beam subjected to the collision load can be pressed,
- wherein the receiving surface has a hook-like projection that is capable of preventing the impact beam pressed to the receiving surface from being disengaged from the receiving surface,
- wherein the receiving surface includes a front side inclined surface that is capable of transforming the collision load from the impact beam applied diagonally from a forward direction to a collision load which is directed in the vehicle widthwise direction, and a rear side inclined surface that is capable of transforming the collision load from the impact beam applied diagonally from a rearward direction to the collision load which is directed in the vehicle widthwise direction,
- wherein the door box is attached to a door inner panel of the door while the door box is inserted into an opening formed in the door inner panel, and
- wherein the door box has a hook portion that is formed in an upper surface thereof and is capable of engaging a periphery of the opening of the door inner panel when the door box is subjected to the collision load and is displaced toward a vehicle cabin.
A vehicle body structure in which a collision load applied to one of vehicle doors from a lateral side thereof is received by a load receiving member of a body via an impact beam and a door box of the door and is transmitted from the load receiving member to a cross member, the load receiving member comprising:
- a load receiving pipe that is formed as a linear tubular body disposed between the right and left doors so as to extend in a vehicle widthwise direction and is capable of transmitting the collision load from the door box of one of the doors to a door box of the other of the doors;
- and
- connecting portions that are capable of supporting the load receiving pipe at positions adjacent to the right and left doors and connecting the load receiving pipe to the cross member,
- wherein the door box has a receiving surface to which the impact beam subjected to the collision load can be pressed,
- wherein the receiving surface has a hook-like projection that is capable of preventing the impact beam pressed to the receiving surface from being disengaged from the receiving surface,
- wherein the receiving surface includes a front side inclined surface that is capable of transforming the collision load from the impact beam applied diagonally from a forward direction to a collision load which is directed in the vehicle widthwise direction, and a rear side inclined surface that is capable of transforming the collision load from the impact beam applied diagonally from a rearward direction to the collision load which is directed in the vehicle widthwise direction,
- wherein the connecting portions are respectively independently disposed in one and the other sides in the vehicle widthwise direction,
- wherein each of the connecting portions includes an upper fixture portion to which the load receiving pipe is secured, and a lower fixture portion which is secured to the cross member, and
- wherein the lower fixture portion has a width greater than the upper fixture portion in the vehicle widthwise direction and is positioned inside of the upper fixture portion in the vehicle widthwise direction.
