Shock-absorption and high-strength concave-convex reinforcement pipe for bicycle or scooter

Abstract

The invention discloses a shock-absorption and high-strength concave-convex reinforcement pipe for a bicycle or a scooter. The shock-absorption and high-strength concave-convex reinforcement pipe comprises a concave reinforcement pipe body and a convex reinforcement pipe body, wherein the concave reinforcement pipe body comprises a tubular body, the radian of the tubular body adapts to and is matched with the radian of the sunk part of a bicycle frame pipe, the convex reinforcement pipe body comprises a tubular arc body obtained after a pipe is cut in the circumferential direction, the radianof the tubular arc body adapts to and is matched with the radian of the protruding part of the bicycle frame pipe, and a cavity between the tubular arc body and the protruding part of the bicycle frame pipe is filled with filler; the concave reinforcement pipe body is connected with the bicycle frame pipe through longitudinal welding lines in the extending direction of the bicycle frame pipe, welding holes are formed in the concave reinforcement pipe body in the vertical direction of the bicycle frame pipe, and the concave reinforcement pipe body penetrates through the welding holes and is connected with the bicycle frame pipe through transverse welding lines; the convex reinforcement pipe body is connected with the bicycle frame pipe through longitudinal welding lines in the extending direction of the bicycle frame pipe. In the shock-absorption and high-strength concave-convex reinforcement pipe, according to the conditions of an arc opening of the pipe, the convex or concave reinforcement pipe body is designed, a hydraulic mould is manufactured, pipes are operated, and the portion between every two pipes is filled with the filler during welding, so that enough matching tightnessand welding strength are ensured.

Description

technical field [0001] The invention relates to the field of aluminum material processing, in particular to a shock-absorbing high-strength concave-convex reinforcing pipe for bicycles or scooters. Background technique [0002] In terms of processing and manufacturing of bicycles (including scooters, electric vehicles, etc.), the industry is pursuing the integration of the overall appearance of the product. After the frame is welded, the weld bead at the joint part will be ground smoothly, so that the two pipes combined together can produce a unified vision. However, due to manual grinding, the welding material after grinding is too small, and the welding status of the joint cannot be judged, and the strength is unstable. Especially, the head pipe end is more prone to safety accidents due to the large force and stress concentration during riding. [0003] It is necessary to solve the problems of insufficient solder and unstable strength after grinding, otherwise it will alwa...

[0002] In terms of processing and manufacturing of bicycles (including scooters, electric vehicles, etc.), the industry is pursuing the integration of the overall appearance of the product. After the frame is welded, the weld bead at the joint part will be ground smoothly, so that the two pipes combined together can produce a unified vision. However, due to manual grinding, the welding material after grinding is too small, and it is impossible to judge the welding status of the joint, and the strength is unstable. Especially, the head pipe end is more prone to safety accidents due to the large force and stress concentration during riding.

[0003] It is necessary to solve the problems of insufficient solder and unstable strength after grinding, otherwise it will always exist as a safety hazard
