Description

M265314 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is about a brand new designer who can adjust the inclination angle of the handlebars in multiple stages, and its angular positioning is indeed correct. [Prior art]

According to the current common electric vehicle handlebar adjustment structure, there is a related patent case as shown in Announcement No. 5 4 7 4 18, which mainly includes a faucet bottom bar, a fixed seat, a positioning bolt, a fixed piece and The paddle [for its detailed structure, please refer to its patent gazette], it mainly uses the upper end of the paddle to press or release it inward, so that the paddle is pulled out or pushed back, and the positioning bolt is The bolt is disengaged or penetrates into the positioning hole of the docking piece of the fixing seat, so that the electric vehicle faucet can freely adjust the forward tilt, backward tilt angle or lock and fix. Taking a closer look at the aforementioned adjustment structure of the handlebar of an electric vehicle, it is mainly positioned by penetrating the bolt of the positioning bolt relative to the positioning hole on the docking piece. However, this positioning angle is often limited by the number of holes in the docking piece. This makes it impossible to adjust the angle of the handle of the faucet at multiple angles. In addition, this positioning structure uses the expansion and contraction of the bolt of the positioning bolt relative to the positioning hole on the butt piece to achieve the purpose of angle control. However, according to the structure disclosed in the previous case, the entire handle only relies on a positioning bolt. For positioning, once the positioning bolt does not protrude into the positioning hole, the handle is easy to be accidentally folded, and its positioning is quite dangerous in use.

[New content] This creation is about an adjustment structure of the handlebar of an electric vehicle, and aims to provide a brand-new designer who can adjust the inclination angle of the handlebar and has a reliable positioning.
