Abstract

An energy absorption device configured to be provided at a front end of a train includes a coupler seat, a support base, a crush pipe, a coupler, a guide member, an energy absorption component and an anti-climbing assembly. The support base is fixedly arranged at the front end of the train; the crush pipe is fixed to the coupler seat; a connecting end of the coupler is inserted into the crush pipe and is slidable with respect to the crush pipe; the guide member has one end fixed to the coupler seat, and another end inserted into the support base and slidable with respect to the support base; the guide member limits an oscillation of the crush pipe; the energy absorption component is provided between the coupler seat and the support base; and the anti-climbing assembly is fixedly arranged on the support base and is compressible.

First claim

What is claimed is:

1. An energy absorption device, configured to be provided at a front end of a train, comprising:
a coupler seat;
a support base configured to be fixedly arranged at the front end of the train;
a crush pipe fixed to the coupler seat;
a coupler having a connecting end inserted into the crush pipe and slidable with respect to the crush pipe;
a guide member having one end fixed to the coupler seat, and another end inserted into the support base and slidable with respect to the support base; wherein the guide member is configured to limit an oscillation of the crush pipe;
an energy absorption component arranged between the coupler seat and the support base; and
an anti-climbing assembly fixedly arranged on the support base and the anti-climbing assembly being compressible,
wherein a stopper, which is a blockage that fills an entire cross section of the guide member, is arranged inside the guide member to limit an extreme position of the connecting end of the coupler when sliding in the crush pipe.

2. The energy absorption device according to claim 1 , wherein a leading member is fixedly arranged on the support base, and the leading member of the support base is slidably connected to the coupler seat to lead a moving direction of the coupler seat.

3. The energy absorption device according to claim 1 , wherein the support base comprises a slide base and a bottom base fixed to each other, and the guide member is slidable with respect to the slide base.

4. The energy absorption device according to claim 3 , wherein the slide base is provided with a leading member for leading the guide member to slide with respect to the slide base, and the leading member of the slide base extends backward through the bottom base.

5. The energy absorption device according to claim 4 , wherein a shear energy absorption component is provided between the leading member of the slide base and the guide member to fix the leading member of the slide base to the guide member.

6. The energy absorption device according to claim 2 , wherein the anti-climbing assembly comprises a lateral anti-climbing and energy absorption component located at each of two sides of the leading member of the support base and an upper anti-climbing and energy absorption component located on an upper surface of the leading member of the support base.

7. The energy absorption device according to claim 6 , wherein a front end surface of the upper anti-climbing and energy absorption component is located at a front side of a front end surface of the lateral anti-climbing and energy absorption component.

8. The energy absorption device according to claim 6 , wherein the lateral anti-climbing and energy absorption component comprises a lateral supporting member fixedly arranged on the support base, a lateral connecting member fixed to the lateral supporting member, a lateral energy absorption member passing through the lateral connecting member and entering into the lateral supporting member, and a lateral anti-climbing member fixedly arranged at a front end of the lateral energy absorption member; and the upper anti-climbing and energy absorption component comprises an upper supporting member fixedly arranged on the support base, an upper connecting member fixed to the upper supporting member, an upper energy absorption member passing through the upper connecting member and entering into the upper supporting member, and an upper anti-climbing member fixedly arranged at a front end of the upper energy absorption member.

9. A rail vehicle, comprising a vehicle head, wherein a front end of the vehicle head is provided with the energy absorption device according to claim 1 .

10. A rail vehicle, comprising a vehicle head, wherein a front end of the vehicle head is provided with the energy absorption device according to claim 2 .

11. A rail vehicle, comprising a vehicle head, wherein a front end of the vehicle head is provided with the energy absorption device according to claim 3 .

12. The energy absorption device according to claim 2 , wherein the support base comprises a slide base and a bottom base fixed to each other, and the guide member is slidable with respect to the slide base.

13. The energy absorption device according to claim 12 , wherein the slide base is provided with a leading member for leading the guide member to slide with respect to the slide base, and the leading member of the slide base extends backward through the bottom base.

14. The energy absorption device according to claim 13 , wherein a shear energy absorption component is provided between the leading member of the slide base and the guide member to fix the leading member of the slide base to the guide member.

15. The energy absorption device according to claim 7 , wherein the lateral anti-climbing and energy absorption component comprises a lateral supporting member fixedly arranged on the support base, a lateral connecting member fixed to the lateral supporting member, a lateral energy absorption member passing through the lateral connecting member and entering into the lateral supporting member, and a lateral anti-climbing member fixedly arranged at a front end of the lateral energy absorption member; and the upper anti-climbing and energy absorption component comprises an upper supporting member fixedly arranged on the support base, an upper connecting member fixed to the upper supporting member, an upper energy absorption member passing through the upper connecting member and entering into the upper supporting member, and an upper anti-climbing member fixedly arranged at a front end of the upper energy absorption member.
