[0024] The present invention will be further described below:

[0025] Please see Figures 1-6 ,

[0026] This utility model discloses a toy that can flip on the surface of a tracked vehicle, including a flipping shell 1, a sphere 2, a tracked vehicle shell 3, a magnet 4, and a track 5. The top of the tracked vehicle shell 3 is provided with a conveyor belt groove 11 for placing a conveyor belt 10. The flipping shell 1 is a hollow cylindrical structure with hemispherical ends, which is placed on the upper surface of the conveyor belt 10. The sphere 2 is an iron ball placed inside the flipping shell 1. A magnet 4 that can attract the sphere 2 is fixed below the conveyor belt 10. The track 5 is provided below the two side walls of the tracked vehicle shell 3. The tracked vehicle shell 3 of this utility model can be moved by the track 5. The magnet 4, fixed to the top of the inner wall of the conveyor belt 10 within the conveyor belt groove 11 at the top of the tracked vehicle housing 3, can drive the ball 2 to move along the length of the inner cavity of the flipping shell 1, thereby causing the flipping shell 1 to continuously flip on the upper surface of the conveyor belt 10. The constantly flipping flipping shell 1 can attract children's curiosity. The flipping process of the flipping shell 1 is full of various mechanical knowledge, which can open up children's thinking, promote their learning and exploration of knowledge, and also have a certain educational significance for children. Furthermore, the image of a soldier is drawn on the outer wall of the flipping shell 1, such as a soldier constantly flipping on the top of the tracked vehicle, which enhances the fun of the toy.

[0027] Furthermore, the outer diameter of the sphere 2 is smaller than the inner diameter of the flip shell 1, making the sphere 2 roll more smoothly inside the flip shell 1; the hollow iron ball of the sphere 2 has a circular cross-section, which reduces the weight of the sphere 2, allowing the flip shell 1 to flip in a vertical plane, or even at the bottom of the plane, without falling off.

[0028] Furthermore, the conveyor belt 10 includes a conveyor belt body 101, a drive roller 102, a driven roller 103, a drive shaft 104, a driven shaft 105, a fixed plate 106, a connecting block 107, a conveyor belt motor 108, a drive gear 109, a driven gear 110, and a conveyor toothed belt 111. The front and rear sides of the inner wall of the conveyor belt body 101 are respectively provided with a drive roller 102 and a driven roller 103 for matching and conveying. The drive roller 102 and the driven roller 103 are respectively axially arranged with the drive roller 102 and driven roller 103. The drive shaft 104 and driven shaft 105 are respectively provided at both ends of the fixed plate 106 for the drive shaft 104 and driven shaft 105 to pass through. The bottom of the fixed plate 106 is connected to the top of a plurality of connecting blocks 107. The bottom of the connecting blocks 107 is connected to the bottom of the inner cavity of the conveyor belt trough 11. The front bottom of the conveyor belt trough 11 is provided with a motor slot for placing the conveyor belt motor 108. The output end of the conveyor belt motor 108 and one end of the drive shaft 104 are respectively connected to... The conveyor belt has a drive gear 109 and a driven gear 110, which are matched and transmitted through the transmission belt 111. When the conveyor belt motor 108 is turned on, it drives the drive gear 109, the driven gear 110, the drive shaft 105, the drive roller 102, and the conveyor belt body 101 to rotate in sequence. The conveyor belt body 101 is fixed to the top of the conveyor belt groove 11 by the fixing plate 106 and the connecting block 107, so that there is a certain gap between the bottom of the conveyor belt body 101 and the bottom of the conveyor belt groove 11, so that it can transmit normally. The magnet 4 is set on the top of the inner wall of the conveyor belt body 101, and there is a very small gap between them. The magnet 4 will not move with the conveyor belt body 101. Therefore, the flipping shell 1 set on the top of the conveyor belt body 101 will be transmitted with the conveyor belt body 101, while the ball 2 inside the flipping shell 1 will not be transmitted with the conveyor belt body 101 due to the magnetic attraction of the magnet 4. Thus, the ball 2 rolls inside the flipping shell 1, causing the flipping shell 1 to keep flipping.

[0029] Furthermore, the magnet 4 is fixed to the top of the transmission mechanism 6. The magnet 4 can move along the top of the inner wall of the conveyor belt body 101 through the transmission mechanism 6, thereby driving the flipping shell 1 to flip at any position on the top of the conveyor belt body 101.

[0030] Furthermore, the transmission mechanism 6 includes a base plate 61, a front baffle 62, a rear baffle 63, an X-axis drive motor 64, an X-axis lead screw 65, an X-axis guide rod 66, an X-axis transmission block 67, a Y-axis drive motor 68, a Y-axis lead screw 69, a bearing seat 70, a Y-axis guide rod 71, and a Y-axis transmission block 72. The base plate 61 is fixed to the inner walls of the two fixing plates 106 on both sides. The front baffle 62 and the rear baffle 63 are respectively fixed to the front and rear sides of the upper surface of the base plate 61. The X-axis drive motor 64 is located at the center of the front of the front baffle 62. The output end of the X-axis drive motor 64 is connected to the bearing seat 68. The front end of the X-axis lead screw 65 is connected to the rear end of the X-axis lead screw 65, which passes through the middle of the front baffle 62 and is fitted into the sleeve hole in the middle of the front wall of the rear baffle 63. The X-axis guide rod 66 is connected between the front and rear walls of the front baffle 62 and the rear baffle 63. The X-axis transmission block 67 has X-axis transmission block threaded holes in the middle of the front and rear walls that are threaded to match the external thread of the X-axis lead screw 65. The front and rear walls of the X-axis transmission block 67 have X-axis guide holes on both sides for the X-axis guide rod 66 to pass through. The Y-axis drive motor 6 is fixed to the top left end of the X-axis transmission block 67. 8. The bearing seats 70 are fixed to the top left and right ends of the X-axis transmission block 67. The left end of the Y-axis lead screw 69 is connected to the output end of the Y-axis drive motor 68, and the right end of the Y-axis lead screw 69 is fixedly connected to the inner ring of the bearing in the bearing seat 70. The left and right walls of the Y-axis transmission block 72 are provided with Y-axis transmission block threaded holes that are threaded and mesh with the external thread of the Y-axis lead screw 69. Two Y-axis guide rods 71 ​​are connected between the bearing seats 70 on both sides. The left and right walls of the Y-axis transmission block 72 are provided with Y-axis guide holes for the Y-axis guide rods 71 ​​to pass through. The magnet 4 is fixed to the top of the Y-axis transmission block 72. The upper surface of the magnet 4 is in contact with the top of the inner wall of the conveyor belt body 101. When the magnet 4 needs to move along the X-axis, the user turns on the X-axis drive motor 64, which drives the X-axis lead screw 65 to rotate, thereby driving the X-axis transmission block 67 to move along the X-axis. When the magnet needs to move along the Y-axis, the user turns on the Y-axis drive motor 68, which drives the Y-axis lead screw 69 to rotate, thereby driving the Y-axis transmission block 72 to move along the Y-axis, thus enabling the magnet 4 to move to any position on the top of the inner wall of the conveyor belt body 101.

[0031] Furthermore, the track 5 includes several track units 51, connecting shafts 52, and connecting heads 53. The track unit 51 has a square structure, and its ends are provided with shaft holes for the connecting shafts 52 to pass through. The length of the connecting shaft 52 is greater than the length of the track unit 51. The end of the connecting head 53 is provided with two connecting head shaft holes 531 for the two ends of the connecting shaft 52 to pass through. The ends of the two adjacent connecting shafts 52 of two adjacent track units 51 are connected by the connecting head 53. Adjacent track units 51 are hinged together by connecting shafts 52 and connecting heads 53 to ensure that the track 5 can move forward stably.

[0032] Furthermore, the track unit 51 includes a base plate 511, a reinforcing plate 512, a reinforcing cover 513, connecting bolts 514, and connecting nuts 515. The base plate 511 has a square structure, with limiting grooves 516 on both sides of its middle portion for inserting limiting members 54. The front and rear sides of the upper and lower surfaces of the base plate 511 are provided with plate grooves 517 for placing the reinforcing plate 512. The outer wall of the reinforcing plate 512 is provided with an "X"-shaped connecting rib 518, and the inner wall of the reinforcing cover 513 is provided with a connecting rib 518 for connecting with the reinforcing rib 512. The connecting groove 519 is connected to the reinforcing plate 512 and the end of the groove 517 are provided with bolt holes for the connecting bolt 514 to pass through. The end of the connecting bolt 514 is matched and connected with the connecting nut 515. By setting the reinforcing plate 512 and the reinforcing cover 513, the strength of the track unit 51 is ensured, and the damage to the track unit 51 is reduced when passing through gravel terrain. The reinforcing plate 512 is connected to the base plate 511 by the connecting bolt 514, which facilitates maintenance and replacement when the reinforcing plate 512 and the reinforcing cover 513 are damaged.

[0033] Furthermore, the limiting member 54 includes a limiting head 541 and a limiting block 542. The limiting head 541 has a square structure, and its ends are provided with limiting head holes 543 for two adjacent connecting shafts 52 to pass through. The inner wall of the limiting head 541 is connected to the limiting block 542, which is in the shape of a "V". By setting the limiting slot into which the limiting member 54 is inserted, it is ensured that the guide wheel 7, the drive wheel 8 and the load wheel 9 will not detach from the track 5.

[0034] Furthermore, the inner side of the track 5 is provided with a guide wheel 7, a drive wheel 8, and a road wheel 9. The guide wheel 7 is sleeved on the front inner wall of the track 5 via an axle, and the drive wheel 8 is sleeved on the rear inner wall of the track 5 via an axle. The outer edges of both ends of the drive wheel 8 are provided with drive teeth 81, the ends of which can be inserted between adjacent connectors 53. The drive wheel 8 is provided with a drive shaft in its axial direction. The drive shaft drives the drive wheel 8 to rotate through a drive mechanism, and the drive teeth 81 follow its rotation, thereby driving the adjacent connectors 53 to move, ultimately realizing the movement of the track. The track 5 rotates; a plurality of road wheels 9 are evenly spaced on the lower inner wall of the track 5. Preferably, the road wheels 9 are fixed by suspension to ensure that when the track 5 contacts a protrusion on the ground, the road wheels 9 can move up and down by suspension, so that the track 5 can easily pass over the protrusion. The guide wheel 7, the drive wheel 8 and the road wheels 9 are provided with a limiting slot for the insertion of the limiting block 542 in the middle of their outer walls. By setting the limiting slot for the insertion of the limiting block 542, it is ensured that the guide wheel 7, the drive wheel 8 and the road wheels 9 will not detach from the track 5.
