The invention provides a bicycle pedal structure. The bicycle pedal structure comprises a crank, wherein a mounting hole is formed in the lower part of the crank and forms a bearing seat; a bearing, which is mounted in the bearing seat; and a pedal structure, which is an integrally-formed whole and comprises a pedal. A mandrel is arranged in the middle of the pedal; the pedal is mounted and fixedon the bearing through the mandrel; the bearing is in interference fit with the bearing seat; the mandrel penetrates through the inner ring of the bearing; the mandrel is provided with a top ring, andthe top ring is used for fixing the inner ring of the bearing; the tail part of the mandrel is provided with a thread, and the mandrel is fixedly arranged on the inner ring of the bearing by screwingin a nut and matching with the top ring; compared with an original double-bearing structure, only one bearing is needed, the cost is reduced, and the risk of problems is reduced; in addition, the pedal is integrally formed, mold opening and manufacturing are easier, the cost is reduced, the pedal is firm and durable due to integral forming, and problems are not prone to occurring.

    本发明提供一种自行车脚踏结构,包括曲柄;所述曲柄下方设有安装孔,所述安装孔形成轴承座;轴承,安装于所述轴承座内;踏板结构,为一体成型的整体,包括:踏板;所述踏板中间设有为芯轴;所述踏板通过所述芯轴安装固定于所述轴承上;所述轴承与所述轴承座为过盈配合;所述芯轴穿过轴承的内圈;所述芯轴上设有顶圈,所述顶圈固定所述轴承的内圈;所述芯轴尾部设有螺纹,通过螺母旋入,配合所述顶圈将芯轴固定安装于所述轴承的内圈上;相对于原先的双轴承结构,本发明只需一个轴承,降低了成本,也使得出现问题的风险降低;另外,踏板采用一体成型制成,开模、制作更为简单,成本降低,一体成型也使得踏板结实耐用,不容易出现问题。
