Combined structure of handlebar and front fork vertical tube of electric bicycle

Abstract

The invention provides a combined structure of a handlebar and a front fork vertical tube of an electric bicycle. The combined structure comprises a handlebar vertical tube, handles on the handlebar vertical tube, a front fork and a bushing. The bushing sleeves the front fork vertical tube. The lower end of the handlebar vertical tube sleeves the bushing, and is fastened and fixed by a hoop. A bottle holder is arranged on the handlebar vertical tube. Anti-slip lines are arranged on the handles. A vertical positioning protrusion is arranged on the bushing. A positioning groove matched with the positioning protrusion is formed in the front fork vertical tube. The combined structure has the advantages that the handlebar vertical tube is directly inserted into the front fork vertical tube and is fixed by the hoop, and the bushing is arranged between the handlebar vertical tube and the front fork vertical tube, so that the combined structure is simple, firm and reliable; the front fork vertical tube is thickened, so that the strength of the front fork vertical tube is enhanced, and riding safety is improved; the handles are coated with sponge layers, so that hand holding comfort level is high, and a certain anti-slip performance is achieved; riding comfort level and safety are high.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle parts, and in particular relates to a combined structure of a handlebar and a front fork riser of an electric vehicle. Background technique [0002] A traditional bicycle includes a front fork, a rear fork, a wheel, a vehicle frame, and a handlebar, wherein the handlebar includes: a handlebar, a stem, and a standpipe, and the standpipe is expanded and tightened on the front fork pipe by a hanging screw. Since the combination structure of the electric vehicle handlebar and the front fork standpipe commonly used on the market is connected by the stem and the standpipe, this brings about a problem: the assembly operation is cumbersome, the man-hours are obviously wasted, and improper operation will cause the standpipe. The tube thread buckle slips, and in serious cases, it will cause a serious safety accident that the handlebars fall off during riding. Since the inner diameter of the eight-p...

Problems solved by technology

Since the combination structure of the electric vehicle handlebar and the front fork standpipe commonly used on the market is connected by the stem and the standpipe, this brings about a problem: the assembly operation is cumbersome, the man-hours are obviously wasted, and improper operation will cause the standpipe. The tube thread buckle slips, and in serious cases, it will cause a serious safety accident that the handlebars fall off during riding. Since the inner diameter of the eight-piece combination of the front fork is a fixed standard part, the diameter of the outer diameter embossing of the front fork is limited, and assembly is required. The stem core also limits the inner diameter of the front fork stem. Due to factors such as riding speed, the damage rate of the front fork stem is extremely high in the market.

Including maintenance and replacement in the later market also wastes man-hours to a certain extent. At present, most electric vehicles on the market have this problem. Solving this professional problem plays a very important role for electric vehicle companies and consumers.
