[0018] See also Figure 1-Figure 4 , a motor hanger mounting structure includes a frame 10, a motor 11, and a motor hanger 12; the frame 10 is configured as a V-shaped structural area in the middle lower part of the electric power-assisted bicycle body, the motor hanger 12 is configured as a U-shaped structure and is detachably mounted on the bottom middle part of the frame 10, the motor 11 is mounted in the middle of the motor hanger 12, and is supported and positioned by the motor hanger 12, and the motors 11 and 2 are spaced apart and are adjustably supported and fixed by multiple sets of adjustable positioning members 20, so as to ensure that the heat generated by the motor 11 during operation can be diffused into the gap space between the motor 11 and the motor hanger 12, and then slowly transferred and released outwards through the motor hanger 12, and side mounting shells 13 are clamped and mounted on both ends of the motor hanger 12, and the motor 11 is sealed and included in the inner side of the motor hanger 12 by the side mounting shell 13, and the inside of the motor hanger 12 is opened and closed by the side mounting shell 13, so that the motor 11 can be easily repaired and replaced;

[0019] In the embodiment of the present invention, an output shaft 29 is provided on one side of the motor 11. An output shaft hole 28 is provided on the side mounting housing 13 corresponding to the output shaft 29. The output shaft 29 movably extends outward through the output shaft hole 28. For an electric power-assisted bicycle, the pedal shaft is typically located at the bicycle's center axis, i.e., the area between the down tube and seat tube of the frame 10. The pedal shaft is where the rider transmits power through the pedals and is typically connected to the crank and chain system.

[0020] The motor 11 in this solution is a mid-mounted motor, which is installed near the center axis of the vehicle body, in the area between the down tube and the seat tube, so that the position of the motor 11 and the pedal shaft are relatively close, but not completely overlapping. The motor 11 detects the rider's pedaling force and speed through sensors and provides corresponding auxiliary power to help the rider ride more easily.

[0021] In one embodiment of the present invention, the motor hanger 12 and the side mounting housing 13 are both made of thermally conductive materials, that is, the heat generated by the motor 11 during operation is transferred to the space between the motor 11 and the motor hanger 12, and then can be gradually transferred and discharged outward along the motor hanger 12 and the side mounting housing 13;

[0022] At the same time, multiple groups of stepped locating pins are installed on the sides of the motor 11, and non-through stepped locating holes 27 are provided on the side mounting shell 13 corresponding to the stepped locating pins. At the same time, multiple mounting clamps 26 are evenly installed on the side wall of the motor hanger 12 corresponding to one side of the side mounting shell 13, and mounting holes 25 are provided on the side wall of the motor hanger 12 corresponding to the mounting clamps 26. The mounting clamps 26 are clamped with the mounting holes 25 to maintain the closed installation between the side mounting shell 13 and the motor hanger 12. At the same time, the mounting clamps 26 are connected to the stepped locating holes 27 in a stepped manner to further improve the accuracy of the installation of the side mounting shell 13 and the motor hanger 12.

[0023] As a preferred embodiment of the present invention, a clamping plate 14 is installed on the top of both ends of the motor hanger 12, and a clamping pin 15 is installed on the side of the end of the clamping plate 14 facing the frame 10. A clamping slot 16 is provided on the frame 10 corresponding to the clamping pin 15. When the motor hanger 12 is connected to the frame 10, the clamping pin 15 and the clamping slot 16 are first clamped and positioned, and then a fastening bolt 18 is threadedly provided on the middle part of the clamping pin 15. A threaded hole 17 is provided inside the clamping slot 16. After the clamping pin 15 and the clamping slot 16 are clamped and positioned, the fastening bolt 18 is rotated to thread it into the threaded hole 17, so as to fix the clamping plate 14 to the frame 10, thereby realizing a detachable connection between the motor hanger 12 and the frame 10, and a bolt cap 19 is installed on the outer end of the fastening bolt 18, which is convenient for externally controlling the fastening bolt 18 to rotate;

[0024] In order to ensure that the latch 15 and the slot 16 are in full contact and engagement, a horizontal structure is provided on the bottom wall of the frame 10 corresponding to the slot 16. After the latch 15 and the slot 16 are engaged, the engaging plate 14 and the frame 10 are in full contact.

[0025] As a preferred embodiment of the present invention, the adjustable positioning member 20 includes a connecting block 24 fixed on the inner wall of the motor hanger 12, and the connecting block 24 is rotatably connected to a screw barrel 23 on one side facing the motor hanger 12. The end of the screw barrel 23 is threadedly connected to a screw rod 22, and the end of the screw rod 22 is installed with an arc-shaped buffer support plate 21. The buffer support plate 21 is in full contact with the outer wall of the motor 11, and its buffering effect is utilized to provide a certain degree of protection for the motor 11. At the same time, the contact force between the buffer support plate 21 and the motor hanger 12 is controlled by rotating the screw barrel 23 to adjust the screw rod 22, thereby ensuring that supporting force is applied to the motor 11 from multiple directions, stably placing it inside the motor hanger 12, and keeping the motor 11 and the motor hanger 12 spaced apart, thereby providing protection for the safe operation of the motor 11.

[0026] The working principle of the present invention is: in the idle position of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in a working order. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. When in use, the clamping plates 14 at both ends of the motor hanger 12 are moved to the lower sides of the frame 10, and then the clamping pin 15 and the clamping slot 16 are clamped and positioned, and then the fastening bolt 18 is driven to be threadedly fixed with the threaded hole 17 by rotating the bolt cap 19, so that the motor hanger 12 and the frame 10 are fixed. Then, place the motor 11 inside the motor hanger 12, pre-plug the output shaft 29 into the output shaft hole 28 on the side mounting shell 13, and then rotate the screw 23 on each set of adjustable positioning parts 20 to make the buffer support plate 21 at the end fully contact with the outer wall of the motor hanger 12, position the motor 11 in multiple directions, and then fix the side mounting shell 13 on both sides of the motor hanger 12. At this time, keep the motor 11 able to run safely. At the same time, when the motor 11 is running, the heat generated by it can be diffused between the motor 11 and the motor hanger 12, and then gradually transferred outward through the motor hanger 12 and the side mounting shell 13 for heat dissipation.

[0027] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
