1. An energy and shock absorbing device for a child car seat, comprising:

  • a seat (1) including a seat body (11);

    a base (2) for supporting the seat (1), the seat (1) being arranged on the base (2) slidably along a path;

    a frame (12) detachably connected to the bottom of the seat body (11), the frame (12) comprising a crossbeam (123);

    a sliding block (122) provided at the bottom of the frame (12), at one or more of a left and right portion of crossbeam (123), and slidably fitting with the base (2);

    a limit block (22) being formed on the base (2) and located in front of the seat (1) in the path along which the seat (1) slides relative to the base (2); and

    an energy absorbing material (4) arranged on a planar supporting surface of the base (2), between the limit block (22) and the crossbeam (123), the energy absorbing material (4) being deformable to provide buffer force when the seat (1) slides towards the limit block (22) and cooperates with the limit block (22) to compress the energy absorbing material (4);

    wherein two sliding rails (21) are provided on the supporting surface for supporting the seat (1) to slide, the sliding rails (21) linearly extending lengthwise along a front-rear direction in the plane of the supporting surface with the energy absorbing material (4) being arranged between the two sliding rails (21);

    wherein the crossbeam and the limit block span between the two sliding rails and the energy absorbing material (4) engages a portion of the crossbeam (123) and the limit block (22) that spans between the sliding rails when the seat slides towards the limit block;

    wherein the energy absorbing material (4) is a honeycomb aluminum; and

    wherein an axis along a lengthwise greatest dimension of each hole of the honeycomb aluminum extends in the front-rear direction of the seat (1).
