The output shaft of the drive motor body 4 is protected by an output shaft protection mechanism 6, preventing power transmission disruption due to collisions between the drive motor body 4 and the wheels.
[0019] Please see Figure 1 , Figure 2 and Figure 3The anti-collision mechanism 5 includes a first mounting frame 8, a protective rod 9, a positioning rod 10, a hollow tube 11, a threaded rod 12, and a threaded sleeve 13. The first mounting frame 8 is configured in two sets, and multiple sets of protective rods 9 are fixedly installed between the two sets of the first mounting frame 8. A positioning rod 10 is fixedly installed at each of the two opposite corners of the bottom of the first mounting plate 1. A hollow tube 11 is fixedly installed at the top of the first mounting frame 8 and at the position corresponding to the positioning rod 10. The positioning rod 10 is inserted into the hollow tube 11. A threaded rod 12 is fixedly installed at the other opposite corner of the bottom of the first mounting plate 1. A threaded sleeve 13, which is threadedly connected to the threaded rod 12, is rotatably connected to the top of the first mounting frame 8 and at the position corresponding to the threaded rod 12.
[0020] When installing the anti-collision mechanism 5, firstly, insert two sets of hollow tubes 11 into the outside of the positioning rod 10. Then, the threaded sleeve 13 corresponds to the threaded rod 12. After rotating the threaded sleeve 13, the threaded sleeve 13 can be threadedly connected to the threaded rod 12. This completes the fixed installation of the first mounting bracket 8 and the protective rod 9. When the stroller is hit by a collision, the first mounting bracket 8 and the protective rod 9 can protect the drive motor body 4 and prevent the drive motor body 4 from being directly damaged by the collision displacement.
[0021] Please see Figure 1 and Figure 3 The output shaft protection mechanism 6 includes a protective plate 14 and a protective sleeve 15. The protective plate 14 is fixedly installed on both sets of the first mounting brackets 8. A "U"-shaped protective sleeve 15 is fixedly installed on one side of one set of the protective plate 14. The protective plate 14 is provided with an avoidance groove 16.
[0022] The protective plates 14 on both sides of the first mounting bracket 8 can protect the two sides of the drive motor body 4, while the protective sleeve 15 can protect the output shaft of the drive motor body 4, and the clearance groove 16 can avoid the output shaft of the drive motor body 4 and facilitate the heat dissipation of the drive motor body 4.
[0023] Please see Figure 1 , Figure 2 and Figure 3 The connecting mechanism 7 includes a drive shaft 17, a second mounting bracket 19, a fixed sleeve 20, an output rotating shaft 21, and a connecting rod 22. The output end of the drive motor body 4 is fixedly connected to the drive shaft 17. A drive groove 18 is provided on one side of the drive shaft 17. The bottom of the second mounting plate 2 is fixedly connected to the fixed sleeve 20 through the second mounting bracket 19. The output rotating shaft 21 is rotatably connected inside the fixed sleeve 20. A connecting rod 22 inserted into the drive groove 18 is fixedly installed on the output rotating shaft 21.
[0024] The second mounting bracket 19 can be used to install the fixing sleeve 20 and the output shaft 21. Then, the drive shaft 17 and drive groove 18 on the output shaft of the drive motor body 4 are connected to the connecting rod 22 of the output shaft 21. The drive motor body 4 is then fixedly installed using the locking bolt 3. This allows the drive motor body 4 to drive the wheel movement. This arrangement can protect the output shaft 21 and drive shaft 17 to prevent collisions from affecting the normal movement of the wheel.
[0025] Please see Figure 1 and Figure 3 The first mounting bracket 8, the protective rod 9, the protective plate 14 and the protective sleeve 15 are all made of rigid materials, and there is a gap between the protective rod 9 and the drive motor body 4.
[0026] Among them, the first mounting bracket 8, guard rod 9, guard plate 14 and protective sleeve 15, which are made of rigid materials, are not easily deformed and have a stronger protective effect. The gap between the guard rod 9 and the motor body 4 can prevent the guard rod 9 from directly colliding with the drive motor body 4 due to the deformation of the guard rod 9 when it is hit.
[0027] Please see Figure 1 and Figure 3 The first mounting bracket 8 has a buffer pad on the side near the drive motor body 4. The buffer pad is in contact with the drive motor body 4. The buffer pad can prevent direct impact on the drive motor body 4 and damage to the drive motor body 4 when the first mounting bracket 8 is in contact with and protecting the motor body 4.
[0028] In use, firstly, the drive motor body 4 is mounted on the frame using locking bolts 3 and the first mounting plate 1. Then, the anti-collision mechanism 5 is installed below the first mounting plate 1. This prevents the drive motor body 4 from being damaged in a collision. The anti-collision mechanism 5 is detachable, facilitating maintenance and replacement of the drive motor body 4. The second mounting plate 2 and connecting mechanism 7 then connect the drive motor body 4 to the wheels. The output shaft of the drive motor body 4 is protected by the output shaft protection mechanism 6, preventing power transmission disruption due to collisions. When installing the anti-collision mechanism 5, firstly, two sets of hollow tubes 11 are inserted into the outside of the positioning rod 10. Then, the threaded sleeve 13 corresponds to the threaded rod 12. Rotating the threaded sleeve 13 allows for threaded connection between the threaded sleeve 13 and the threaded rod 12, thus completing the first installation. The first mounting bracket 8 and the protective rod 9 are fixedly installed. When the stroller is hit by a collision, the drive motor body 4 can be protected by the first mounting bracket 8 and the protective rod 9 to prevent the drive motor body 4 from being directly damaged by the collision displacement. The protective plates 14 set on both sides of the first mounting bracket 8 can protect the two sides of the drive motor body 4, while the protective sleeve 15 can protect the output shaft of the drive motor body 4. The clearance groove 16 can avoid the output shaft of the drive motor body 4 and facilitate the heat dissipation of the drive motor body 4. The second mounting bracket 19 can install the fixed sleeve 20 and the output shaft 21. Then, the drive shaft 17 and drive groove 18 on the output shaft of the drive motor body 4 are connected to the connecting rod 22 of the output shaft 21. Then, the drive motor body 4 is fixedly installed using the locking bolt 3. In this way, the drive motor body 4 can easily drive the wheels. This setting can protect the output shaft 21 and the drive shaft 17 to prevent collisions from affecting the normal movement of the wheels.
