Electric distribution box
View Patent ↗An electric distribution box, includes a box body for being placed in a vehicle room; a mounting portion which is provided on the box body for being fixed to a vehicle body, and a rupture induction portion which is provided at a box body side of the mounting portion for inducing the rupture of the mounting portion by an impact upon collision of a vehicle so as to separate the box body from the vehicle body. The mounting portion is divided into two virtual sections by a line passing through a center of an insertion hole of the mounting portion, the longitudinal axis being substantially parallel to an advance direction of the vehicle. The rupture induction portion is provided at one of the two virtual sections which is disposed in a direction away from a direction of laterally-inclining of the box body upon collision of the vehicle.
1. An electric distribution box, comprising:
a box body for being placed in a vehicle room;
a mounting portion, which is provided on the box body for being fixed to a vehicle body, and having an insertion hole; and
a rupture induction portion, which is provided at a box body side of the mounting portion for inducing the rupture of the mounting portion by an impact upon collision of a vehicle so as to separate the box body from the vehicle body,
wherein the mounting portion is divided into two virtual sections by a longitudinal line passing through a center of the insertion hole of the mounting portion, the longitudinal line being substantially parallel to an advance direction of the vehicle; and
wherein the rupture induction portion is arranged at one of the two virtual sections which is disposed on a side in a first direction for allowing the box body to move in a second direction perpendicular to the advance direction of the vehicle upon collision of the vehicle; and
wherein the first direction is opposite to the second direction.
2. The electric distribution box as set forth in claim 1 , wherein the rupture induction portion is a hole portion formed on the mounting portion.
3. The electric distribution box as set forth in claim 1 , wherein the box body has a front wall, rear wall and a side wall regarding to the advance direction of the vehicle;
wherein the mounting portion is provided at the rear wall;
wherein an auxiliary mounting portion is provided at a front wall side of the side wall; and
wherein an elongated hole for fixing purposes is formed on the auxiliary mounting portion so as to extend substantially along a line interconnecting the center of the mounting portion and a center of the auxiliary mounting portion.
4. The electric distribution box as set forth in claim 1 , further comprising an interference portion, which is provided on the box body, and the interference portion having a convexly-curved surface for allowing the box body to escape in a direction away from an automotive part when the box body is disengaged from the vehicle body by an impact upon collision of a vehicle and interfered with the automotive part.
5. The electric distribution box as set forth in claim 4 , wherein the interference portion includes ribs arranged in a mesh pattern.
