When this protective structure is missing, if the power motor is stalled or subjected to reverse impact force during operation, it will cause irreversible damage to the internal deceleration structure of the power motor.
[0006] Therefore, it is necessary to develop a new electronic ball controller gear structure that can protect the power motor. Summary of the invention

Implementation
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-4 , an embodiment provided by the utility model:
[0028] The gear structure of the three-section variable electronic ball controller includes a cross-member assembly and a moving assembly located at the bottom of the cross-member assembly and movably connected thereto. The moving assembly includes a connecting column 23 and a power source assembly. The connecting column 23 is movably engaged with the cross-member assembly. The power source assembly includes a motor mounting slot 24, a power motor 26 and a gear plate 25. The power motor 26 is installed in the motor mounting slot 24. The power motor 26 is connected to the gear plate 25 through a drive shaft. The gear plate 25 is meshedly connected to the cross-member assembly. A spring 27 is fixed on the outside of the power motor 26. The spring 27 extends to the outside of the motor mounting slot 24 and is fixedly connected to the connecting column 23. There are three springs 27 from top to bottom.
[0029] The gear plate 25 is driven by the power motor 26 to rotate in the cross member assembly, thereby driving the cross member in the cross member assembly to rotate in both directions. When the connecting column 23 is engaged with the cross member assembly, the upper part is hinged by bolts, and the bolts are connected to the cavity at the top of the connecting column 23.
[0030] During the bidirectional rotation of the cross member, the power motor 26 and the gear plate 25 are in a vertical force direction. Therefore, when the power motor 26 is subjected to excessive torque or is always stuck, the torque exceeds the force supported by the spring 27, and the size of the spring 27 will retreat backward to avoid slipping between the gear plate 25 and the cross member combination, thereby protecting the life of the power motor 26 and the internal structure.
[0031] There is a 2 mm gap inside the motor installation slot 24 , and the gap cooperates with the spring 27 to support the power motor firmly.
[0032] A large through hole 31, a small through hole 32 and an internal gear 33 are provided at the head and tail of the cross member assembly. The large through hole 31 is located at the back of the cross member assembly and has a small through hole 32 in the center. The internal gear 33 is fixed to the inner wall of the large through hole 31. A groove 311 is provided on the inner wall of the large through hole 31. A convex groove 312 matching the groove 311 is provided on the outside of the internal gear 33, and a snap-fit connection is formed between the groove 311 and the convex groove 312.
[0033] The large through hole 31 is fixedly connected to the internal gear 33 with the convex groove 312 through the groove 311, and a small through hole 32 is opened in the center of the large through hole 31. The small through hole 32 is penetrated by the connecting column 23, and the small through hole 32 is covered with bolts that penetrate into the connecting column 23. The bolts can prevent the connecting column 23 from being separated from the cross member.
[0034] The moving component also includes a moving component housing 21 and a rolling bottom wheel 22. A connecting column 23 is arranged in the moving component housing 21, and a rolling bottom wheel 22 is arranged at the bottom. The rolling bottom wheel 22 is a 360° rotating rolling ball that is evenly distributed.
[0035] like Figure 2 As shown, there are 5 rolling wheels 22 under each of the moving component housings 21, which are large in number and can rotate 360°, thus ensuring safe and effective sliding of the moving component. Even if a rolling wheel is stuck or falls off, its movement trajectory will not be affected.
[0036] The cross member assembly includes a first cross member 11, a second cross member 12, and a third cross member 13. The tail of the first cross member 11 is connected to the head of the second cross member 12, the tail of the second cross member 12 is connected to the head of the third cross member 13, and the second cross member 12 is stacked on the first cross member 11 and the third cross member 13, and is movably connected through a connecting column 23.
[0037] In the three-section variable electronic ball controller gear structure of the present invention, the cross member assembly includes three overlapping cross members, namely the first cross member 11, the second cross member 12 and the third cross member 13. The head and tail lower ends of the first cross member 11 and the head and tail lower ends of the third cross member are provided with a moving assembly, wherein the connecting column 23 in the moving assembly located at the bottom of the head of the first cross member 11 and the bottom of the tail of the third cross member passes through the corresponding small through-hole 32 and is fixed by bolts. The moving assembly at the tail of the first cross member 11 and the bottom of the head of the third cross member 13, the internal connecting column 23 needs to pass through the combined small through-hole 32 of the tail of the second cross member 11 and the head of the second cross member 12 and the combined small through-hole 32 of the head of the third cross member 13 and the tail of the second cross member 12, and are all reinforced by bolts.
[0038] During the movement of the three-section variable electronic ball controller, the meshing rotation connection between the gear plate 25 and the internal gear 33 is utilized to drive the moving component to rotate along with the gear plate 25, thereby driving the cross member to realize bidirectional rotation. When the four moving components start to work together, the variability of the training route of the three-section ball controller is driven, the reaction ability and adaptability of the trainees in dribbling are trained, and the training effect is enhanced.
[0039] Furthermore, during the movement, when the power motor 26 is subjected to excessive torque or is always stuck, the torque exceeds the force supported by the spring 27, and the size of the spring 27 will retreat to avoid it, causing slippage between the gear plate 25 and the internal gear 33, thereby protecting the life of the power motor 26 and the internal structure.
