As shown in fig. 5, the guide roller 22 is internally provided with a cavity 222; a rubber block 223 is fixedly connected in the cavity 222; when the vehicle collides with the guide roller 22, the rubber block 223 in the cavity 222 of the guide roller 22 buffers the kinetic energy generated by the collision, and reduces the kinetic energy generated when the vehicle collides with the guide roller 22, so that the collision between the vehicle and the guide roller 22 is not easy to generate rigid impact.
As shown in fig. 3, a pair of first through holes 24 are formed in the side wall of the protective frame 2, which is close to the baffle plate 12; a pair of second through holes 121 are formed in the side wall, close to the protective frame 2, of the baffle 12; the first rack plate 131 is in sliding fit with the inner side wall of the first through hole 24, and the first rack plate 131 is in sliding fit with the inner side wall of the second through hole 121; when the first rack plate 131 slides along the outer side wall of the straight rod 13 under the driving of the spur gear 36, the first rack plate 131 slides along the side wall of the first through hole 24 and the side wall of the second through hole 121, and the first rack plate 131 is limited by the arrangement of the first through hole 24 and the second through hole 121, so that the sliding of the first rack plate 131 is more stable.
Working principle: firstly, the mounting seat 1 is mounted in the embedded groove 41 in the tunnel body 4, when a vehicle running in the tunnel body 4 accidentally collides against the inner side wall of the tunnel body 4, the vehicle firstly passes through the speed reducing belt 43, and the vehicle is primarily decelerated under the action of the speed reducing belt 43; when the vehicle laterally impacts the inner side wall of the tunnel body 4, the vehicle firstly impacts the guide roller 22, a rubber block 223 is arranged in the guide roller 22, and kinetic energy generated by the impact is buffered through the rubber block 223, so that the kinetic energy generated when the vehicle impacts the guide roller 22 is reduced; when a vehicle collides with the guide roller 22, the impact force generated by the collision drives the protective frame 2 to slide towards the inside of the first chute 11, the first spring 23 is extruded in the sliding process of the protective frame 2, and the first spring 23 is compressed and deformed, so that the kinetic energy generated by the vehicle collision is converted into the elastic potential energy of the first spring 23, the buffer of the vehicle is realized, and the driver is protected; when the vehicle laterally impacts the guide roller 22, the vehicle drives the guide roller 22 to rotate, the laterally impacted vehicle is guided by the guide roller 22, so that the wheel on one side of the vehicle, which is close to the protection frame 2, falls into the guide groove 14, after the wheel falls into the guide groove 14, the wheel presses the straight plate 331 to slide downwards, so that the straight plate 331 contacts with the sliding plate 31, under the cooperation of the arc 333 and the inclined surface 311, the straight plate 331 pushes the sliding plate 31 to compress the second spring 34 and slide towards the inside of the second sliding groove 15, the sliding plate 31 drives the second rack 35 to slide along the third sliding groove 16 in the sliding process, and the second rack 35 is meshed with the straight gear 36, so that the straight gear 36 and the second rotating shaft 32 are driven to rotate, and in the rotating process of the second straight gear 36, the straight gear 36 drives the first rack 131 to slide along the outer side wall of the straight rod 13, so that the pressing plate 132 at the end part of the first rack 131 is gradually close to the guide roller 22 and extrudes the guide roller 22; when the pressing plate 132 and the guide roller 22 are mutually pressed, the rubber protrusions 221 and the rubber plate 133 are pressed and deformed, so that the friction force of the contact part of the pressing plate 132 and the guide roller 22 is increased, the guide roller 22 is not easy to rotate, and when the guide roller 22 is blocked to rotate, the friction mode of the contact part of the guide roller 22 and the side wall of the vehicle is changed from rolling friction to sliding friction, so that the friction force of the contact part of the guide roller 22 and the vehicle is increased, the speed of the vehicle is reduced under the action of the friction force, and the driver strives for time to park the vehicle; in the sliding process of the straight plate 331, the side wall of the straight plate 331 is gradually far away from the rubber strip 173, when the straight plate 331 loses contact with the rubber strip 173, the push plate 171 drives the rubber strip 173 to extend out of the fourth chute 17 under the elastic force of the fourth spring 172, so that the rubber strip 173 contacts and extrudes the wheel, the speed of the wheel is reduced by the friction force between the rubber strip 173 and the wheel, the vehicle is further decelerated, and the backing plate 18 arranged at the bottom of the guide groove 14 is used for supporting the straight plate 331, so that the third spring 332 is protected; when the vehicle runs in the tunnel body 4, the illumination lamp 421 at the bottom of the U-shaped frame 42 illuminates the tunnel, so that the vehicle running in the tunnel has a better sight line, and the safety coefficient of running is improved.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
