The invention discloses a centrally-mounted motor mounting surrounding structure for a bicycle, and relates to the technical field of bicycle machining, the centrally-mounted motor mounting surrounding structure comprises a frame assembly, a gear box and a motor, the frame assembly comprises a frame plate, a first butt joint hole, an upper cover plate and a lower cover plate, and the first butt joint hole is formed in the inner side of the top of the frame plate; an upper cover plate is arranged on the outer side of the top of the frame body plate, a lower cover plate is arranged on the outer side of the bottom of the frame body plate, the gear box body is arranged on the inner side of the frame body plate, a second butt joint hole is formed in the outer side surface of the gear box body, and a driven rotating shaft is arranged on the outer side of the right portion of the gear box body. The frame body plate is a complete frame body, compared with a traditional U-shaped semicircular middle motor installation surrounding structure, the frame body plate of the complete frame body is adopted, it can be guaranteed that the whole frame body plate is evenly stressed in the connecting process of the frame body plate and the vehicle frame, mechanical fatigue borne by the frame body plate can be greatly reduced, and the service life of the frame body plate is prolonged. Therefore, the welding between the equipment and the frame is more stable and firmer.

    本发明公开了一种自行车用中置马达安装包围结构,涉及自行车加工技术领域,包括框体组件、齿轮箱体和马达,所述框体组件包括框体板、第一对接孔、上盖板和下盖板,所述框体板的顶部内侧开设有第一对接孔,且框体板的顶部外侧安置有上盖板,所述框体板的底部外侧设置有下盖板,所述齿轮箱体安置于框体板的内侧,且齿轮箱体的外侧表面开设有第二对接孔,所述齿轮箱体的右部外侧设置有从动转轴。本发明框体板为一个完整的框体,相较于传统的U型半圆形中置马达安装包围结构,通过采用完整框体的框体板,能保证框体板与车架衔接过程中整体受力均匀,这能极大的降低框体板收到的机械疲劳,从而保证设备与车架之间焊接的更加稳定牢固。
