[0025] like Figures 1 to 5 As shown, a frame with a buffer structure comprises a frame body 1, a mounting pad 2 is mounted on the outer side of the frame body 1, a plurality of buffer bases 5 are arranged on the outer side of the mounting pad 2, a push block 4 is welded on the rear wall surface of the buffer base 5, a buffer cavity 3 for sliding the push block 4 is opened on the mounting pad 2, a buffer pad 8 is bonded to the outer wall surface of the buffer base 5, a telescopic buffer part 6 for buffering the impact force brought by the buffer base 5 is arranged between two adjacent push blocks 4 and between the push block 4 and the buffer base 5, and a movable buffer part 7 for mitigating the impact force when the two buffer bases 5 are close to each other is arranged between two adjacent buffer bases 5;

[0026] Specifically, the buffer pad 8 can receive the impact force in the first time when a collision occurs, and buffer, absorb and disperse the impact force on the outward side of the frame body 1, thereby reducing the damage of the impact force to the frame body 1; the telescopic buffer part 6 can be deformed accordingly when the buffer base 5 is hit, thereby offsetting the impact force generated during the collision, achieving a buffering effect, enhancing the buffering protection effect on the outer side of the frame body 1, effectively improving the integrity of the frame body 1 during driving, and improving driving safety.

[0028] Specifically, the damping spring 602 and the damping telescopic rod 603 can be arranged to cause telescopic deformation when the buffer base 5 is subjected to impact force, thereby effectively absorbing and buffering the impact force and reducing the damage to the frame body 1 caused by the collision.

[0029] like Figure 5 As shown, the movable buffer part 7 includes a positioning plate 702, and a casting integral positioning plate 702 is installed on one side wall of the buffer base 5, and two vertically symmetrical brackets 703 are welded on the positioning plate 702, and a plurality of equally distributed rotating rollers 704 are rotatably connected between the two brackets 703, and a receiving cavity 701 capable of accommodating the two brackets 703 and the plurality of rotating rollers 704 is opened on the other side wall of the buffer base 5;

[0030] Specifically, the rotating roller 704 can be moved into the accommodating cavity 701 when the buffer base 5 is hit and moves closer to the buffer base 5 on the other side, thereby shortening the distance between the two buffer bases 5 and reducing the damage caused by the collision between the two buffer bases 5.
