Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a power box. Background Art

[0002] Building blocks offer numerous advantages, not only in terms of children's development but also in their inherent versatility and interactivity. By creating unique models from basic cube shapes, building blocks help children understand spatial relationships—front and back, left and right, up and down—and thus enhance their spatial imagination. Furthermore, the building process requires children to constantly experiment, revise, and even redesign, which helps cultivate their logical thinking and problem-solving skills.

[0003] Most self-propelled assembly toys currently on the market suffer from limited functionality and scalability. Their gameplay is relatively simple, focusing primarily on assembly and construction. This can lead to boredom after extended playtime, reducing children's continued interest and desire to explore the toys. The toys are less engaging and interactive, and children are unable to experience the joy of dynamic driving or control. Utility Model Content

[0066] The power box of the present invention has a plurality of splicing holes 101 provided on the main box body 50. After the motor drive module 55 is spliced ​​with the wheel 19, the motor drive module 55 drives the wheel 19 to rotate. Specifically, the battery 58 provides power to the circuit board 56 and the motor 52. The pop-up switch 57 triggers the circuit board 56 to control the operation of the motor 52, which in turn drives the wheel 19 via the motor drive shaft 60. The motor drive module 55 is located inside the splicing main box body 50, and the wheels 19 are in contact with the ground, pressing the splicing main box body 50 downward. The motor drive module 55 and the splicing main box body 50 move relative to each other in the height direction. The first transmission spacing 61 provides a moving space for the motor drive shaft 60. At least a part of the motor drive shaft 60 is located in the first transmission spacing 61. The pressing piece 59 squeezes the pop-up switch 57, and the pop-up switch 57 triggers the motor 52 to rotate through the circuit board 56. The motor 52 drives the motor drive shaft 60 to rotate, and the motor drive shaft 60 drives the wheels 19 to rotate, thereby enabling the splicing toy car to move automatically, thereby enhancing the fun and interactivity of the power box.

[0067] It should be noted that the height of the first transmission interval 61 is such that after pressing the splicing main box body 50 , the pressing member 59 can press the pop-up switch 57 and trigger the motor 52 to transmit.

[0068] As one embodiment, the pop-up switch 57 is a conventional technology. The circuit board 56 sets the rotation time of the motor 52. The motor 52 stops rotating after the rotation time reaches the set time.

[0069] As one embodiment, the main box transmission opening 51 is elliptical, and the major axis of the ellipse is arranged along the height direction, so that the motor transmission shaft 60 and the main box transmission opening 51 have a first transmission distance 61 in the height direction.

[0070] Furthermore, the motor drive module 55 includes an inner housing 70, which is provided with a motor receiving slot 71, an inner housing transmission opening 72, a circuit board receiving slot 73, and a battery receiving slot 75.

[0083] As one embodiment, one of the first limiting portion 23 and the second limiting portion 14 is a protrusion and the other is a groove structure, and the protrusion is engaged in the groove. Preferably, the protrusion and the groove are annular to improve the reliability of the engagement between the first limiting portion 23 and the second limiting portion 14.

[0084] Furthermore, the main box transmission groove 13 and the main box transmission bar 22 extend in the axial direction. The main box transmission bar 22 is inserted into the main box transmission groove 13 in the axial direction. The main box transmission groove 13 guides the assembly of the main box transmission bar 22, thereby improving the assembly accuracy of the wheel body 10 and the motor transmission member 20.

[0085] Furthermore, the first stopper 23 is located at the end of the transmission connection cavity 21 facing the wheel body 10, and the second stopper 14 is located at the end of the transmission boss 11 away from the motor transmission member 20.
