The invention belongs to the field of crumple energy absorption and specifically provides an induced crumple energy absorbing device and a bracket of an electric automobile high-tension distribution box. The invention aims at solving a problem that a crumple structure on an automobile body is hard to reach an ideal crumple effect in the prior art. In order to solve the purpose, the induced crumple energy absorbing device comprises a first crumple piece and a second crumple piece which are connected together through a connecting piece; a limiting piece is arranged at one end, close to the second crumple piece, of the first crumple piece; and a bending structure is arranged on at least one of the first crumple piece and the second crumple piece. When the first crumple piece and the second crumple piece are extruded by each other under stress, one end of the second crumple piece can be disconnected with the first crumple piece and can move to a position to be propped against the limiting piece in a longitudinal direction of the first crumple piece so that the first crumple piece and / or the second crumple piece are bent towards a preset direction through the bending structure. Therefore, the induced crumple energy absorbing device can reach an ideal crumple effect under an effect of outside force.
Description
technical field [0001] The invention belongs to the field of collapse energy absorption, and specifically provides an induced collapse energy absorption device and a bracket for a high-voltage distribution box of an electric vehicle. Background technique [0002] The high-voltage power distribution unit (PDU) of electric vehicles is usually set in the front compartment of electric vehicles (equivalent to the engine compartment of fuel vehicles). When an electric vehicle has a frontal collision, the front cabin will be deformed by force, which often causes the PDU (moving) to collide with other components in the front cabin and be damaged, especially when the PDU is arranged in the front position of the front cabin state. In order to prevent the PDU from being damaged when the electric vehicle collides, a collapse energy-absorbing device is often provided in the front cabin to fix the PDU. When a car collides, the collapse energy-absorbing device can bend and deform in a pr...
