[0029] According to some embodiments of the present invention, the mounting seat 1 is interference fit with the energy absorbing tube 41, and the mounting seat 1 is sleeved on the other end of the energy absorbing tube 41. When the anti-climbing tooth 3 is subjected to impact force, the energy absorbing tube 41 moves longitudinally along the inner wall of the seat hole of the mounting seat 1, and abuts against the punch 22 after moving a certain distance. The position of the punch 22 corresponds to the position of the induction groove 42. The energy absorbing tube 41 continues to move longitudinally, and the punch 22 tears the energy absorbing tube 41 along the induction groove 42, thereby playing a role in buffering and absorbing energy.
[0030] According to some preferred embodiments of the present invention, the anti-climbing teeth 3 are welded to the energy absorbing tube 41 .
[0031] According to the utility model, a rail vehicle anti-climbing energy absorption device is provided. Figures 1 to 4 As shown, an induction notch 43 is formed on a side of the induction groove 42 away from the anti-climbing tooth 3 , and the induction notch 43 abuts against the punch 22 .
[0032] In this embodiment, the inducing notch 43 is provided to abut against the punch 22 to prevent the energy absorbing tube 41 from rotating during the longitudinal movement, thereby preventing the position of the punch 22 and the inducing groove 42 from shifting and affecting the energy absorbing effect of the energy absorbing device.
[0033] According to the utility model, a rail vehicle anti-climbing energy absorption device is provided. Figure 4 As shown, the inner side wall of the ring 21 cooperates with the edge of the punch 22 to form a curling molding cavity 23.
[0034] In this embodiment, by providing the curling molding cavity 23 , the torn energy absorbing tube 41 can move along the curling molding cavity 23 to undergo continuous curling deformation.
[0035] According to some preferred embodiments of the present invention, the curling molding cavity 23 is a continuous gradient cavity with a large front end and a small rear end, and the curling molding cavity 23 is a closed or semi-closed structure.
[0036] According to the rail vehicle anti-climbing energy absorption device provided by the present invention, the mounting seat 1 is fixedly connected to the body of the rail vehicle via bolts 5 .

Figure 3 As shown, the energy absorbing assembly 4 includes four induction grooves 42 , and the four induction grooves 42 are evenly distributed on the outer side wall of the energy absorbing tube 41 .
[0041] In this embodiment, by setting four induction grooves 42, the energy absorbing tube 41 forms metal plates of uniform size after being torn, increasing the tearing position, improving the energy absorption efficiency in the curling molding cavity 23 and the energy absorption effect of the energy absorbing tube 41.
[0042] According to the utility model, a rail vehicle anti-climbing energy absorption device is provided. Figure 4 As shown, the guide assembly 2 includes four punches 22 , which are evenly distributed on the inner wall of the ring 21 and correspond one-to-one to the four induction grooves 42 .
[0043] In this embodiment, punches 22 corresponding to the induction grooves 42 are provided to facilitate tearing and energy absorption of the energy absorbing tube 41 .
[0044] The technical solution of the present invention is further explained below in conjunction with a specific embodiment. It should be noted that this specific embodiment is only for those skilled in the art to better understand the technical solution of the present invention, and should not be regarded as an unreasonable limitation on the protection scope of the present invention.
[0045] Example 1
[0046] When the anti-climbing energy absorption device of the rail vehicle is hit, the impact force is transmitted to the energy absorption tube 41 through the anti-climbing teeth 3, and the energy absorption tube 41 retreats longitudinally under the guidance of the mounting seat 1. When the induced notch 43 of the energy absorption tube 41 contacts the punch 22 of the guide mold, the energy absorption tube 41 continues to move longitudinally and is evenly torn. The torn metal tube continues to move along the curling molding cavity 23 and undergoes continuous curling deformation under the action of the curling molding cavity 23, while generating plastic deformation force.
[0047] Compared with the prior art, the rail vehicle anti-climbing energy absorption device of the present invention has the following technical effects:
[0048] 1. Applying the principle of energy dissipation caused by plastic deformation due to tearing and continuous curling of metal tubes, the anti-climbing energy absorption device for rail vehicles adopts a lightweight design and has a simple structure;
