Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a slippage type energy-absorbing guardrail comprises an outer frame 1, wherein inner frames 2 are fixedly arranged inside the outer frame 1, the number of the inner frames 2 is two, a lower transverse rod 3, an upper transverse rod 4 and a middle plate 6 are arranged between one opposite sides of the two inner frames 2, a fixing hole 5 is formed in the bottom of the upper transverse rod 4, high-resilience sponge 7 is bonded on the front surface of the middle plate 6, only the outer frame 1 and the inner frames 2 are foamed, the middle plate 6 is made by adopting an integral plastic suction process, the high-resilience sponge 7 is bonded on the middle plate 6, when the slippage type energy-absorbing guardrail is extruded by external force, a passenger can be protected by the outer frame 1 and the inner frames 2, meanwhile, the slippage type energy-absorbing guardrail mainly depends on slight deformation of the middle plate 6 and resilience of the high-resilience energy-absorbing sponge 7, so as to achieve the effect of full protection, a fixing screw 8 is arranged inside the upper transverse rod 4, a slippage lock 9 is fixedly arranged outside, the bottom fixed mounting of intermediate lamella 6 has hasp 10, utilize slipping lock 9 and hasp 10 to carry out the joint with intermediate lamella 6 and last horizontal pole 4, intermediate lamella 6 rotates through the pivot with two interior frames 2 simultaneously and is connected, when the impact force is greater than the setting value, slipping lock 9 drops from hasp 10 in, and then intermediate lamella 6 begins to rotate, can avoid the knee impact force too big like this, the protection knee, also avoid the broken passenger that stabs of intermediate lamella 6 simultaneously, mounting hole 11 has been seted up on outline 1, installation square hole 12 has been seted up to outline 1 bottom, only set up mounting hole 11 and installation square hole 12 in the bottom of outline 1, the installation fixed point has been reduced, the aesthetic property of the device has been improved.

Specifically, outline 1 and interior frame 2 surface are made by the PU foaming, and outline 1 and interior frame 2's inside all is provided with skeleton 13 simultaneously to when guaranteeing that the device receives the impact, not fragile can also play the guard action to the passenger.

Specifically, the middle plate 6 is integrally formed by plastic suction, and can slightly deform to achieve an energy absorption effect.

Specifically, the middle plate 6 is rotatably connected with the two inner frames 2 through a rotating shaft, and the middle plate 6 can rotate when the impact force is too large.

Specifically, the middle plate 6 is clamped with the lock catch 10 through the slip lock 9 between the middle plate 6 and the upper cross rod 4, and the middle plate 6 is fixed, so that the middle plate 6 is limited and fixed during normal use.
