The quick release rod comprises a rod end and a handle, and the rod end is inserted into the fixing portion.
[0007] The fixing part includes a groove and a fixing hole. The fixing hole is arranged at the bottom of the groove. The groove and the fixing hole are a concave stepped structure.
[0008] The invention also comprises a quick release seat, which comprises a quick release seat body, a convex part and a through hole. A convex part is arranged on one side of the quick release seat body, and the through hole is arranged in the convex part and the quick release seat body, and the convex part and the groove are matched with each other.
[0009] Among them, the groove includes multiple positioning grooves, one end of the protrusion includes multiple positioning heads, and each of the multiple positioning grooves is matched with each of the multiple positioning heads in a concave-convex manner; or, the groove includes multiple positioning heads, one end of the protrusion includes multiple positioning grooves, and each of the multiple positioning grooves is matched with each of the multiple positioning heads in a concave-convex manner.
[0010] One side of the fixed disc body includes a plurality of circular holes.
[0011] The rod end includes a thread, the fixing hole includes a thread, and the thread of the rod end engages with the thread in the fixing hole.
[0012] To summarize, when the fixing seat is fixed on the hub motor, it can be quickly assembled and positioned through the protrusions and grooves; when the positioning head cooperates with the positioning groove, the quick release seat will roll when it is loosened, thereby preventing the motor and wires from being damaged.

[0037] In order to make the technical features, contents and advantages of the present invention and the effects that can be achieved more clearly, the present invention is hereby described in detail as follows in the form of embodiments in conjunction with the accompanying drawings and attachments. The drawings used therein are only for illustration and auxiliary description purposes, and may not be the actual proportions and precise configurations after the implementation of the present invention. Therefore, the proportions and configuration relationships of the attached drawings should not be interpreted or limited to the application scope of the present invention in actual implementation. This should be stated in advance.
[0038] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the referred device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0039] See also Figure 1 , a three-dimensional schematic diagram of a first embodiment of a fixing device for a hub motor of the present invention. As shown in the figure, a first embodiment of a fixing device for a hub motor includes a fixing seat 11, a quick release seat 21 and a quick release rod 31.
[0040] The fixing seat 11 includes a fixing rod 12 and a fixing plate 13. The fixing rod 12 is disposed on one side of the fixing plate 13. The fixing rod 12 includes a fixing portion 14, and the fixing plate 13 includes a plurality of circular holes 15. The circular holes 15 are fixed to the wheel hub motor through at least one fixing member. The fixing member can be a screw, a bolt, a rivet or a fastener.
