[0006] A further improvement of this utility model of a motor with a locking structure shaft is that four sets of limiting plates are provided, which are evenly distributed circumferentially on the end face of the shaft away from the motor body. The cross-sectional area of ​​the inner sidewalls of the four sets of limiting plates is circular, and the cross-sectional area of ​​the circle formed by the cross-sectional area of ​​the inner sidewalls of the four sets of limiting plates gradually decreases from the side closer to the motor body to the side farther away from the motor body.

[0007] A further improvement of this utility model of a motor with a locking structure shaft is that the limiting plate and the shaft body are integrally formed.

[0008] A further improvement of this utility model of a motor with a locking structure shaft is that a protrusion is provided on the inner side wall of the groove, the protrusion is used to lock with the external mechanical structure limit phase, and the protrusion is integrally formed with the groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model achieves connection and locking of the external mechanical structure by setting a limiting plate, thereby improving the locking performance; at the same time, the design of the groove structure and the protrusion, together with the external mechanical structure, also ensures the connection stability of the motor shaft.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3As shown, a motor with a locking structure shaft includes a motor body 1, which includes a motor shaft for connecting to an external mechanical structure. The motor shaft includes a shaft body 2, and a groove 3 is formed on the end face of the shaft body away from the motor body towards the motor body. A locking portion is provided on the edge of the end face of the shaft body away from the motor body, extending away from the motor body. The locking portion includes at least two sets of spaced-apart limiting plates 4. The inner sidewalls of the limiting plates are arc-shaped, and the distance between the inner sidewalls of the two limiting plates gradually decreases from the side closer to the motor body to the side farther away from the motor body. The two limiting plates cooperate to clamp the connecting shaft of the external mechanical structure, thereby improving the locking performance.

[0021] Furthermore, four sets of limiting plates are provided, evenly distributed circumferentially on the end face of the shaft away from the motor body. The inner sidewalls of the four sets of limiting plates are arc-shaped, and the line connecting the cross-sections of the inner sidewalls of the four sets of limiting plates forms a circle. The cross-sectional area of ​​the circle formed by the line connecting the cross-sections of the inner sidewalls of the four sets of limiting plates gradually decreases from the side closer to the motor body to the side farther away from the motor body. Preferably, the outer sidewalls of the limiting plates are also arc-shaped. The limiting plates have a certain degree of plasticity, and after the external connecting shaft is inserted, the limiting plates can clamp the connecting shaft, improving the locking performance.

[0022] Specifically, the limiting plate and the shaft are integrally formed.

[0023] Furthermore, a protrusion is provided on the inner sidewall of the groove, which is used to engage with the external mechanical structure for positioning. The protrusion and the groove are integrally formed. A positioning groove can be provided on the external connecting part, which engages with the protrusion to further achieve a stable connection.
