The invention provides a seat pipe shock absorption device for an electric bicycle. The seat pipe shock absorption device comprises a saddle pipe arranged on a seat pipe, wherein the saddle pipe is sheathed on the lower part of the seat pipe, the upper part of the inner wall of the saddle pipe is provided with a shaft sleeve, the seat pipe passes through the shaft sleeve, the lowest end of the seat pipe is lower than the lowest end of the shaft sleeve, a hanging wire is arranged in the saddle pipe, a shock absorption spring is sheathed outside the hanging wire, a built-in hanging screw nut is arranged under the saddle pipe, and the shock absorption spring is positioned between the lowest end of the shaft sleeve and the built-in hanging screw nut. The seat pipe shock absorption device has the beneficial effects that the structure is simple, the shock absorption effect is good, and the applicability is high.
Description
technical field [0001] The invention belongs to the field of bicycle accessories, in particular to a seat tube shock absorber in a bicycle. Background technique [0002] At present, with the improvement of people's living standards, people's means of transportation are not limited to bicycles, but replaced by cars and electric vehicles. However, due to the high maintenance costs of automobiles and the serious pollution of exhaust emissions, most people choose electric vehicles as a means of transportation. tool; while the saddle tube is one of the essential parts on the electric vehicle, the traditional saddle tube is a single straight tube, which is rigidly connected with the frame and the saddle, and its functions: one is to support the saddle; The outer hoop of the frame is used to adjust the height of the saddle. However, since a single straight pipe has no cushioning function, people will feel very uncomfortable when driving on rough roads (especially electric vehicles...
