Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-5 , an anti-collision device for an electric vehicle frame that is convenient to adjust, comprising a U-shaped frame 1, an arc-shaped anti-collision beam 2 is arranged at one end of the U-shaped frame 1, a plurality of cross-shaped buffer plates 21 are arranged inside the arc-shaped anti-collision beam 2, adjustable shock-absorbing components are arranged at both ends between the U-shaped frame 1 and the arc-shaped anti-collision beam 2, the two shock-absorbing components are also provided with sliding components, and an adjustment mechanism for adjusting the distance between the arc-shaped anti-collision beam 2 and the U-shaped frame 1 is also arranged inside the U-shaped frame 1;

[0024] The shock absorbing assembly includes a piston cylinder 3, a circular rotating ring 5 is threadedly connected to the outer side of the piston cylinder 3, a circular moving tube 4 is arranged at one end of the circular rotating ring 5 and located on the outer side of the piston cylinder 3, and the circular moving tube 4 is slidably connected to the piston cylinder 3, a piston rod 9 is slidably connected to the inside of the piston cylinder 3, a circular connecting block 6 is fixed to the end of the piston rod 9 away from the piston cylinder 3, a rigid spring 7 is arranged between the circular connecting block 6 and the circular moving tube 4 and located on the outer side of the piston cylinder 3, an arc-shaped connecting block 8 is arranged at the end of the circular connecting block 6 away from the circular moving tube 4, and the arc-shaped connecting block 8 is close to one end of the arc-shaped anti-collision beam 2 and is rotatably connected to the arc-shaped anti-collision beam 2;

[0025] An external thread groove is provided on the outside of the piston cylinder 3, and an internal thread groove is provided inside the circular rotating ring 5. The piston cylinder 3 and the circular rotating ring 5 are threadedly connected through the external thread groove and the internal thread groove. Through the threaded connection between the circular rotating ring 5 and the piston cylinder 3, the rotation of the circular rotating ring 5 can drive the circular moving tube 4 to slide on the outside of the piston cylinder 3.

[0026] A plurality of rectangular sliders are fixed inside the circular moving tube 4, and a rectangular slide groove adapted to the rectangular slider is also arranged on the outside of the piston cylinder 3. The circular moving tube 4 and the piston cylinder 3 are slidably connected through the cooperation of the rectangular slider and the rectangular slide groove, so that the circular moving tube 4 can slide on the outside of the piston cylinder 3. The sliding of the circular moving tube 4 causes the rigid spring 7 to deform, thereby adjusting the damping stroke of the shock absorbing assembly and adjusting the buffering strength of the shock absorbing assembly.

[0027] When the buffering force needs to be adjusted, the circular rotating ring 5 is rotated. The rotation of the circular rotating ring 5 enables the circular moving tube 4 to slide on the outside of the piston cylinder 3, and the rectangular slider to slide inside the rectangular slide groove, thereby adjusting the distance between the circular moving tube 4 and the circular connecting block 6, and thereby adjusting the buffering performance of the device;

[0028] The adjusting mechanism includes a circular rotating member 12, a first transverse gear 13 is fixed to one end of the circular rotating member 12, a transverse connecting rod 17 is fixed to one end of the first transverse gear 13 away from the circular rotating member 12, a second transverse gear 14 is fixed to one end of the transverse connecting rod 17, the first transverse gear 13 and the second transverse gear 14 have opposite thread rotation directions, the second transverse gear 14 is threadedly connected to a rectangular sliding block 15 on the outer side of the first transverse gear 13, a circular connecting column 16 is fixed to the bottom of the rectangular sliding block 15, the bottom of the circular connecting column 16 is rotatably connected to the circular moving tube 4 through a bearing, the rectangular sliding block 15 is located inside the U-shaped frame 1 and is slidably connected, the circular connecting column 16 runs through the inside of the U-shaped frame 1 and is slidably connected to the U-shaped frame 1, and the transverse connecting rod 17 runs through the inside of the U-shaped frame 1 and is rotatably connected to the U-shaped frame 1 through a bearing;

[0029] The circular rotating member 12 is provided with an inner hexagonal groove. By providing the inner hexagonal groove, the circular rotating member 12 can rotate inside the U-shaped frame 1. A transverse slide groove is provided inside the U-shaped frame 1. The rectangular sliding block 15 is located inside the transverse slide groove and is slidably connected to the U-shaped frame 1 through the transverse slide groove. By providing the transverse slide groove, the rectangular sliding block 15 can slide inside the U-shaped frame 1.

[0030] The sliding assembly includes a circular fixed column 10, which is fixed at the middle position of the U-shaped frame 1 near one end of the arc-shaped anti-collision beam 2, and a circular sliding column 11 is slidably connected inside the circular fixed column 10, and the circular sliding column 11 is close to one end of the arc-shaped anti-collision beam 2 and is fixedly connected to the arc-shaped anti-collision beam 2, so that the arc-shaped anti-collision beam 2 can slide longitudinally toward the direction of the U-shaped frame 1;

[0031] The hexagonal piece is used to enable the circular rotating member 12 to rotate inside the U-shaped frame 1. The rotation of the circular rotating member 12 enables the first transverse gear 13, the transverse connecting rod 17 and the second transverse gear 14 to rotate. The rotation of the first transverse gear 13 and the second transverse gear 14 causes the movement directions of the two rectangular sliding blocks 15 to be opposite. The circular connecting column 16 is connected to the circular moving tube 4 by rotation, and the arc-shaped connecting block 8 is connected to the arc-shaped anti-collision beam 2 by rotation, so that the arc-shaped anti-collision beam 2 can be moved, thereby enabling the spacing between the U-shaped frame 1 and the arc-shaped anti-collision beam 2 to be adjusted.

[0032] Working principle: When the buffering force needs to be adjusted, the circular rotating ring 5 is rotated. The rotation of the circular rotating ring 5 enables the circular moving tube 4 to slide on the outside of the piston cylinder 3, and the rectangular slider can slide inside the rectangular slide groove, thereby adjusting the distance between the circular moving tube 4 and the circular connecting block 6, and thereby adjusting the buffering performance of the device;

[0033] By using the setting of the hexagonal piece, the circular rotating member 12 can rotate inside the U-shaped frame 1. The rotation of the circular rotating member 12 enables the first transverse gear 13, the transverse connecting rod 17 and the second transverse gear 14 to rotate. The rotation of the first transverse gear 13 and the second transverse gear 14 makes the movement directions of the two rectangular sliding blocks 15 opposite. Through the rotational connection between the circular connecting column 16 and the circular moving tube 4 and the rotational connection between the arc-shaped connecting block 8 and the arc-shaped anti-collision beam 2, the arc-shaped anti-collision beam 2 can be moved, thereby allowing the distance between the U-shaped frame 1 and the arc-shaped anti-collision beam 2 to be adjusted.
