The inner diameter of thin tube 10 is smaller than the inner diameter of thick tube. Buffer energy-absorbing component absorbs and moderates the impact force received by side pole 5 in working state. The movable plate 13 that is rotatably connected with the antiskid plate 11 is arranged on the antiskid plate 11, and the main beam 1 is connected with the movable plate 13. The locking mechanism is arranged on the antiskid plate 11, and the locking mechanism includes the vertical plate 15, the horizontal plate 16 and the driving assembly 17. The vertical plate 15 is arranged at the bottom of the antiskid plate 11, and the vertical plate 15 is perpendicular to the antiskid plate 11. The horizontal plate 16 is slidably arranged on the vertical plate 15. The driving assembly 17 is arranged on the antiskid plate 11. The driving assembly 17 drives the horizontal plate 16 to slide along the vertical plate 15 in the height direction in the working state. The driving assembly includes the screw rod 171, the worm wheel 172 and the worm 173. The sliding groove is arranged on the vertical plate 15, and the guide rod is arranged in the sliding groove. One end of the horizontal plate 16 is inserted into the sliding groove and is slidably connected with the inner wall of the sliding groove. The guide rod penetrates through the horizontal plate 16 and is slidably connected with the horizontal plate 16. The screw rod 171 is inserted into the sliding groove and is rotatably connected with the vertical plate 15. The screw rod 171 penetrates through the horizontal plate 16 and is screwedly connected with the horizontal plate 16. The worm wheel 172 is coaxially connected with the screw rod 171. The worm 173 is rotatably connected with the antiskid plate 11 and is meshed with the worm wheel 172. The plum blossom belt column hole 1731 is arranged on the outer end surface of the worm 173. The locking mechanism supports the main beam 1 in cooperation with the mounting plate 2 in the working state. The pedal 19 is arranged on both sides of the frame 18. The main beam 1 is connected with the frame 18 through the mounting plate 2 and the preloading hole. The antiskid plate 11 is connected with the pedal 19 through the locking mechanism.
[0029] In the embodiment, the main beam 1 is connected with the pre-installed hole on the motorcycle frame 18 through bolts, the anti-skid plate 11 falls on the pedal 19 of the frame 18, and the vertical plate 15 is on the side of the pedal 19 away from the frame 18. By means of a special tool inserted into the plum blossom hole 1731 and rotating the worm 173, the worm 173 drives the worm wheel 172 to rotate, the worm wheel 172 drives the screw rod 171 to rotate, so that the horizontal plate 16 rises and clamps the pedal 19 from below through the anti-skid plate 11, the anti-skid plate 11 increases the outer contour of the frame, cooperates with the guard bar structure to make the gap between the motorcycle body and the ground when the motorcycle falls, and helps to prevent the rider's legs from being crushed. When the motorcycle falls, the side bar 5 lands first, the frame weight drives the piston 4 to slide through the pull rod 6, until the side bar 5 abuts against the outer end surface of the hollow column 3, in this state, the side bar 5 cooperates with the anti-skid plate 11 to keep the gap between the landing side of the motorcycle body and the ground within a safe range. The spring 8 is retracted in the state of the side bar 5 close to the main beam 1 and buffers the whole motorcycle body, avoiding the motorcycle body indirectly and rigidly colliding with the ground due to the landing of the side bar 5, thereby effectively preventing the motorcycle body structure from deforming due to the inertia of the collision. The side bar 5 is retracted, at this time, the air in the hollow column 3 is pushed by the piston 4 and quickly discharged along the one-way exhaust pipe 9 and the thin pipe 10, during the process of the motorcycle body righting, the spring 8 releases potential energy and pushes the piston 4 back, the external air can only slowly enter the hollow column 3 along the thin pipe 10, so that the side bar 5 restores to the original state at a slower speed. The structure is beneficial to prevent the side bar 5 from rigidly colliding with the ground, thereby preventing the side bar 5 from being bent due to the instantaneous heavy pressure, prolonging the service life of the side bar 5, and is beneficial to prevent the motorcycle body from indirectly and rigidly colliding with the ground, thereby playing a good protection role on the motorcycle.
