Abstract

The invention relates to a central motor for an electric power-assisted bicycle. The central motor comprises a shell and a radiating net. The top end of the shell is connected with a top cover. Fastening bolts are installed on the surfaces of the front end and the rear end of the top cover. A first shaft rod is inserted into the top cover in a penetrating manner. The bottom end of the first shaftrod is connected with a lantern ring located under the shell. The heat dissipation net is embedded in the outer surface of the bottom of the shell. A first notch is formed in the surface of a carryingplate. An inner plate is installed in the carrying plate. A protruding rod is welded to the lower surface of the carrying plate. A groove is formed in the upper surface of the bottom plate. A third through hole corresponding to the first through hole in position is formed in the inner side of a second notch. The diameter of the first through hole is the same as that of the third through hole. According to the invention, it is convenient to disassemble the central motor and maintain internal parts, heat dissipation is convenient, and the bearing plate is high in rigidity and convenient to use.

Description

technical field [0001] The invention relates to the technical field of electric power-assisted bicycles, in particular to a central motor for electric power-assisted bicycles. Background technique [0002] Bicycles are a common means of transportation in daily life. Riding a bicycle is not only convenient for travel, but also can exercise the body. Therefore, there are many bicycles on the market. Among them, bicycles that use electric energy for power assistance have gradually become a popular direction in the market, and electric power-assisted bicycles The internal mid-mounted motor is a very important component; [0003] However, when the existing mid-mounted motors on the market are in use, it is difficult to disassemble, which makes it difficult to maintain the internal parts, and the heat dissipation is not convenient, the rigidity of the load-bearing plate is not strong enough, and it is not convenient to use, so the current development A kind of middle-mounted moto...
