The utility model discloses have the crashproof pad that strikes cushioning effect and can lead to, its whole constitutes good level gradient energy dissipation system by nose, frame post group, energy-absorbing unit, rear portion support component structure. Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses set up the energy-absorbing unit between the frame post, thereby take place the casualties problem through the energy-absorbing unit in order to reduce vehicle acceleration too big.
In the process of impact energy absorption, the frame column is connected with the road surface through the rocker and slides on the guide rail through the guide hole, the rocker structure is a steel plate with two overlapped ends, the friction between the frame column and the ground is reduced by welding the bottom end of the frame column, and the stumbling resistance formed by overlarge friction between the frame column and the ground in the impact process is reduced.
When the vehicle hits the nose, the guide rail structure can play a guiding role for the vehicle, namely the vehicle cannot be out of control in the process of safe speed reduction.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Please refer to fig. 1-4, in the embodiment of the present invention, an anti-collision pad for expressway, belong to TS level and have impact buffering effect and guidable anti-collision pad, energy-absorbing unit including external frame energy dissipation system and internal core energy dissipation, three wave plates 1 pass through bolted connection by frame post 2, the external frame of whole anti-collision pad is fixed through preceding stiff end 3 and back stiff end 4, the anti-collision pad front portion is equipped with curved nose 5 of D word, when the wave plate group received the striking motion, frame post 2 slided on the road surface along guide rail 7 through wane 6, be equipped with internal core energy-absorbing unit between frame post 2, in this embodiment, energy-absorbing unit adopts honeycomb 8.
Referring to fig. 1-4, in an embodiment of the present invention, when a vehicle hits the nose 1, the guide rail structure will guide the vehicle, i.e. the vehicle will not run away during the process of safe deceleration; in the process of impact energy absorption, the frame column 2 is connected with the road surface through the wane 6 and slides on the guide rail 7, the wane 6 is a steel plate with two overlapped ends, the friction between the frame column and the ground is reduced by welding the bottom end of the frame column, and the friction between the frame column and the ground is reduced because the friction between the frame column and the ground is overlarge in the impact process; and the nose end 5, the corrugated plate 1, the honeycomb structure 8 and the rear support 4 form a structure which realizes integral multi-stage energy dissipation, realizes the stepped reduction and offset of impact kinetic energy of the vehicle, and effectively avoids the injury of the impact kinetic energy to passengers while continuously dissipating the energy through the deformation of the energy dissipation structure.
Referring to fig. 5-6, in another embodiment of the present invention, the nose end 5 is connected to the rear frame 2 through a bolt in the external frame energy dissipation system, the three wave plate 1 is connected to the frame column 2 through a bolt, the rear fixing end 4 is connected to the frame column through a bolt, and the front fixing end 3 and the rear fixing end 4 are connected to the ground through anchor bolts.
Specifically, as shown in fig. 5-6, the rear support 4 includes a base and a plurality of ribs 9 arranged on the base. The base is provided with a ground connection threaded hole 10 and is installed in front of a highway ramp through a bolt and the ground connection threaded hole 10. The side end part of the rib plate 9 is welded with a steel plate, the middle lower part of the steel plate is provided with a guide rail hole for connecting a guide rail, the guide rail 7 sequentially passes through the guide hole arranged at the bottom of the support part to extend to a position far away from the rear support 4 and is fixed by the front fixed end 3, and as shown in fig. 7, the guide rail 7 is connected with the front fixed end and the rear fixed end through the guide rail hole.
