[0012] Compared with the prior art, a wheel hub motor installation structure for a children's wheel adopting the above technical solution has the following beneficial effects:
[0013] 1. In use, when it is necessary to install the tire, the staff presses the top of the rear of the fixing buckle on the connecting column, and the elastic force provided to the fixing buckle by the spring in the circular groove, when no external force is received, the spring can make the fixing buckle be located above the fixing compartment, and when external force acts, the fixing buckle can be moved downward as a whole, and when the fixing buckle is pressed until it is flush with the notch, the connecting column is inserted into the wheel hub, and when the connecting column reaches the corresponding position, the top of the fixing buckle is released, and the fixing buckle moves upward due to the elastic force of the spring, so that the top of the front side of the fixing buckle is stuck in the slot, thereby fixing the connecting column in the wheel hub, and when disassembly is required, it is only necessary to press the rear end of the fixing buckle until it is flush with the notch to pull out the connecting column, and the device can quickly realize the connection and disassembly of the connecting column and the wheel hub, which is convenient for the later replacement and inspection of the wheel hub. By means of the sliding arrangement of the groove at the bottom of the fixing buckle and the limiting column, the movement range of the fixing buckle can be limited, and the fixing buckle can be prevented from deviating from its normal position when moving up and down, thereby ensuring the stable operation of the system. The wheel hub and the tire are connected and fixed, so that the tire can be rotated through the connecting column. By means of the sliding arrangement of the slide groove and the two fixing columns, the connecting column can be limited to improve the accuracy of the connecting column 1 during the connection process. The fixing column provides an additional support point for the device, enhances the stability of the overall structure, and also realizes the precise adjustment of the position of the connecting column, thereby improving the applicability and flexibility of the system.
[0014] 2. During use, the drive motor and the connecting column are connected by a coupling. The coupling is not only responsible for transmitting the torque of the drive motor, but also ensures the stability of the drive motor transmission. The bearing ring is arranged at the front end of the bottom plate shell, which provides a stable support point for the output end of the drive motor and reduces the friction between the drive motor and the bottom plate shell. The threaded holes arranged on the bottom plate shell and the connecting holes arranged on the outer cover shell are used to fix the bottom plate shell and the outer cover shell by bolts, thereby protecting the drive motor from the influence of the external environment. The limit strip arranged on the inner side of the outer cover shell is slidably arranged in the limit grooves on the left and right sides of the bottom plate shell, thereby realizing the limitation of the outer cover shell and improving the overall stability.
[0015] 3. By setting the glass cover at the observation port, the staff can observe the operation of the drive motor more clearly through the glass cover, which is more convenient for checking the drive motor. The sound insulation layer set on the inner wall of the outer cover shell can effectively reduce the noise generated by the drive motor during operation. BRIEF DESCRIPTION OF THE DRAWINGS
