[0033] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present disclosure.
[0034] Figure 1 A structural schematic diagram of a motor seat of an electric bicycle provided by the present embodiment is shown, Figure 2 A structural schematic diagram of the motor seat and the motor 100 provided by the present embodiment is shown.

The edge of the first punch side plate 2 is welded on the welding surface of the punch base plate 1. The edge of the second punch side plate 3 is welded on the welding surface of the punch base plate 1. Wherein, the first accommodating space 4 for accommodating the motor 100 is formed between the punch base plate 1, the first punch side plate 2 and the second punch side plate 3.
[0035] The motor seat of the electric bicycle provided by the embodiment adopts a stamping process to manufacture key components of the motor seat, i.e., a stamped base plate 1, a first stamped side plate 2, and a second stamped side plate 3. Compared with the widely used forging process in the traditional manufacturing method, the stamping process has incomparable advantages. The forging process often needs to go through complex heating, forging, and subsequent finishing processes. This process not only consumes time and effort, but also requires a large amount of energy and expensive equipment, resulting in high manufacturing costs. The stamping process is quite different. It relies on high-precision molds and can achieve accurate molding of parts through one-time stamping operation, without the need for complex heating and forging steps, and without the need for subsequent finishing processes, thereby significantly reducing energy consumption and equipment investment costs at the source. More importantly, the stamping process perfectly integrates with modern automated production lines, realizing a high-speed continuous production mode. On the automated production line, after the raw materials are accurately fed and positioned, they can be instantly transformed from raw materials to finished products under the rapid action of the stamping machine. This efficient production method not only greatly improves production efficiency and shortens product delivery cycle, but also significantly improves product consistency and quality stability due to reduced human intervention. Therefore, the stamped base plate 1, the first stamped side plate 2, and the second stamped side plate 3 manufactured by the stamping process not only inherit the significant features of low cost and high efficiency of the stamping process, but also play a crucial role in the processing of the motor seat. They not only significantly reduce the overall manufacturing cost of the motor seat, saving a large amount of production cost for the enterprise, but also improve the processing efficiency.

[0037] Further, the stamped base plate 1 is an arc-shaped plate, and the edges of the first stamped side plate 2 and the second stamped side plate 3 are arc lines that fit the arc-shaped plate. The arc-shaped stamped base plate 1 can adapt to the layout of the electric bicycle frame, so that only one plate needs to be stamped during processing and manufacturing, which can meet the layout requirements of the electric bicycle frame.
[0038] Further, the stamped base plate 1 and the first stamped side plate 2 form a second accommodating space 5 that accommodates the cover 101 of the motor 100, and the stamped base plate 1 can cover the cover 101 of the motor 100 to effectively protect the cover 101 of the motor 100.
