Technical Field
[0001] The utility model belongs to the technical field of bicycle structures, and particularly relates to a folding structure of a power-assisted bicycle bracket. Background Art
[0002] A folding power-assisted bicycle is an electric vehicle that can be folded, and it is a super-lightweight electric vehicle. However, it is different from ordinary electric vehicles. Its unique features lie in its small product volume, foldability, delicate design, excellent materials, and excellent manufacturing process. The production materials are made of special lightweight materials such as magnesium alloy, and the weight is extremely light.
[0003] The folding part of a traditional folding power-assisted bicycle is usually connected by a hinge. After the folding power-assisted bicycle is unfolded, the two parts are fixed together by a buckle. This connection method makes the connection part not firm enough, which is an important factor affecting the load-bearing capacity of the folding power-assisted bicycle. In order to increase the firmness of the connection of the folding power-assisted bicycle, a folding structure of a power-assisted bicycle bracket is provided.
[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

By setting a U-shaped card sleeve to clamp on two connecting brackets, the force on the connection part of the two connecting brackets can be avoided during use, and the firmness of the folding structure can be increased. By inserting a plug rod into the limit sleeve, the U-shaped card sleeve can be limited to prevent it from falling off.
[0006] To achieve the above purpose, the utility model provides a folding structure of a power-assisted bicycle bracket. The folding structure includes two connecting brackets, a hinge, and a connecting piece. The two connecting brackets are combined to form a bicycle crossbeam. The connecting brackets are connected by a hinge and a connecting piece, and the hinge and the connecting piece are respectively located on both sides of the bicycle crossbeam. The folding structure further includes a reinforcement component for strengthening the connection part of the two connecting brackets.
[0007] Chute grooves are formed on both sides of the connecting bracket.
[0008] The reinforcement component includes a U-shaped card sleeve. Symmetrically distributed card strips are provided on both inner walls of the U-shaped card sleeve. The opening of the U-shaped card sleeve faces downward, and the card strips thereon are respectively clamped into the corresponding chute grooves.
[0009] Furthermore, the connecting piece includes a first fixed shaft and a second fixed shaft respectively fixed on the two connecting brackets, and a hook is rotatably provided on the first fixed shaft.
[0010] Further, the folding structure further includes four limiting components for limiting the reinforcement components, and the four limiting components are respectively fixed at both ends of the side plates of the U-shaped sleeve.
[0011] Further, the limiting component includes a limiting sleeve fixed on the connecting bracket and a shaft sleeve fixed on the U-shaped sleeve. A horizontal insertion rod is slidably arranged on the shaft sleeve. One end of the insertion rod is inserted into the corresponding limiting sleeve, and a connecting rod is vertically fixed above the other end. A spring is fixedly connected between the connecting rod and the shaft sleeve.
[0012] Further, a driving block is fixed on the connecting rod.
[0013] Further, a control component for controlling the movement of the limiting component is provided on the reinforcement component.
[0014] Further, the control component includes an L-shaped bracket fixed above the U-shaped sleeve. A sliding shaft is slidably arranged on the top plate of the L-shaped bracket. A pressing block is fixed at the upper end of the sliding shaft, and a first connecting strip is vertically fixed at the lower end. Second connecting strips are vertically fixed at both ends of the first connecting strip, and triangular blocks are fixed at both ends of the second connecting strip. Under the action of the spring, the inclined surface on the triangular block contacts the upper edge of the side close to the limiting sleeve of the driving block.
[0015] Further, a protective sleeve is fixed above the top plate of the L-shaped bracket, and the pressing block is located inside the protective sleeve.
[0016] The folding structure of a power-assisted bicycle bracket proposed by the present utility model can bring the following beneficial effects:
[0017] 1. The folding structure of the present utility model can avoid the force on the connection part of the two connecting brackets during use by setting the U-shaped sleeve to clamp on the two connecting brackets, increasing the firmness of the folding structure.
