The arrangement direction of the notch structure 1161d can be adjusted according to actual requirements, that is, the notch structure 1161d can be arranged along a preset direction, so that the first tube 1161b can be bent towards the preset direction. The preset direction may be any direction. In this embodiment, the notch structure 1161d includes a first notch 1161e and a second notch 1161 f. The first and second notches 1161e and 1161f are disposed in opposite directions.

In the left-right direction of the atv 100, the second segment 1161h is bent leftward relative to the first segment 1161g through the first notch 1161e, and the second segment 1161h is bent rightward relative to the third segment 1161j through the second notch 1161 f. The first and third segments 1161g and 1161j are disposed substantially parallel and the first segment 1161g extends substantially in a front-to-rear direction. The notch 1161d may be formed by laser cutting, manual cutting, or the like. The notch structure 1161d may be a triangular prism, a triangular pyramid, or the like, and the shape of the notch structure 1161d may be adjusted according to actual needs, and only the first tube 1161b needs to be bent.

In one implementation, the third main beam 1161 has a substantially rectangular cross-section, i.e., the first square tube 1161b has a substantially rectangular cross-section, and the second square tube 1161c has a substantially rectangular cross-section. The first tube 1161b includes a first side 1161k, a second side 1161m, a third side 1161n, and a fourth side 1161 p. The notch structure 1161d at least divides the first side surface 1161k, the second side surface 1161m, and the third side surface 1161n, that is, the fourth side surface 1161p of the first tube 1161b is in a connected state, so that at least one side surface of the first tube 1161b is in an undivided state. It can be understood that the notch structure 1161d at least divides any three sides of the first tube 1161b, and the specific divided three sides can be adjusted according to actual requirements.

Specifically, taking the first segment 1161g and the second segment 1161h as an example, the first side surface 1161k after being divided includes a first surface on the first segment 1161g and a second surface on the second segment 1161h, the second side surface 1161m after being divided includes a third surface on the first segment 1161g and a fourth surface on the second segment 1161h, and the third side surface 1161n after being divided includes a fifth surface on the first segment 1161g and a sixth surface on the second segment 1161 h. In this embodiment, the first tube 1161b is bent with the fourth side 1161p as a bending surface, the first surface and the second surface are joined together, the third surface and the fourth surface are joined together, and the fifth surface and the sixth surface are joined together, thereby completing the bending of the first tube 1161 b. It will be appreciated that the bends of the first and second segments 1161g, 1161h are first bends and the bends of the second and third segments 1161h, 1161j are second bends. The second bending mode and the first bending mode are basically consistent and opposite in bending direction.

In one implementation, the first tube 1161b includes a first cut and a second cut divided by a gap structure 1161 d. Wherein the intersection line of the first and second cut surfaces is located on the fourth side 1161 p. After the first tube 1161b is bent with the fourth side 1161p as a bending surface, the first cut surface and the second cut surface are substantially attached to each other. An angle η formed by the first section and the second section is greater than or equal to 0 DEG and less than or equal to 90 deg. Specifically, the angle η formed by the first tangent plane and the second tangent plane is not less than 15 ° and not more than 75 °. In the present embodiment, the angle η formed by the first cut surface and the second cut surface is not less than 30 ° and not more than 60 °. Through the arrangement, the bending angle of the first square tube 1161b can be controlled through the range of the control angle eta, so that the pipe fitting requirements of different frames 11 are met. In addition, by controlling the range of the angle η, the process defect of the bent piece can be overcome, the surface of the first square tube 1161b is prevented from sinking, the strength of the first square tube 1161b is improved, the electrophoresis effect of the first square tube 1161b is improved, and therefore the strength of the all-terrain vehicle 100 is improved.
