An activity box includes two pairs of wheels having blind holes, two axles having two ends releasably insertable into the blind holes, and a box defining a space having a defined volume sufficiently large to fit the axles. The wheels include a first magnetically attractable component. The axles include a second magnetically attractable component secured at each end of each axle. The axles have a length spanning a width of the box, which has two pairs of through holes on two opposing sides to accommodate the axles, such that the axles are threaded through the through holes. The two pairs of wheels are rotatably attached to the box by magnetically coupling the first magnetically attractable component to the second magnetically attractable component, such that the activity box is configured to be used as a cart that can be rolled over a surface.

A toy vehicle control mechanism for performing stunts includes a rod permitting a user to selectively manipulate a toy vehicle. The rod includes a rod-tip and a shaft, and a connection piece is secured to a toy vehicle as an interface for the rod-tip. The rod-tip is formed to include an opening having a shape and a size so that the connection piece can travel around within the opening and a notch at a tip edge of the rod-tip such that the toy vehicle can be manipulated by selectively engaging the notch with various portions of the connection piece, the notch having a shape and a size permitting a selected portion of the connection piece to enter into the notch without the selected portion of the connection piece penetrating into the opening.

Recreational device including support including first guide defining main axis, slider movably constrained to the support and movable along the main axis, at least one covering element configured to be detachably constrained to the support, elastic element constrained to the slider and to the support and acting between them along the main axis. The elastic element defines a rest configuration wherein it is in a rest position between slider and support and an operating configuration wherein slider and support are in contrast to the elastic element. The covering element includes at least a first interaction surface, the slider includes at least one component protruding outwards and defining at least a second interaction surface configured to interact with the first interaction surface, and the second interaction surface is configured to undo the connection between covering element and support when the elastic element is in operating configuration.

An unpowered downhill autonomous car kit is provided for a user to build. The kit includes a control circuit board, a servo, and a roadway detection sensor. The control circuit board is programmed by a user to interpret patterns marked on a race course that are detected by the roadway detection sensor, and then the control circuit board instructs the servo to steer the car based on the detected roadway patterns. The challenge is for the user to program the car kit in a manner such that during a race, the car will avoid vertical barriers on the race course by correctly interpreting the patterns viewed by the roadway detection sensor. The roadway patterns are intentionally not consistent as the car moves from one roadway segment to the next, so as to increase the technical challenge.

The present disclosure provides a child-mother toy, including: a first assembly and a second assembly. The second assembly includes a supporting member, a triggering subassembly, a unfolding subassembly and an ejection subassembly, and the triggering subassembly, the unfolding subassembly and the ejection subassembly are disposed to the supporting member. Before the triggering subassembly is triggered, the unfolding subassembly is folded at the supporting member so as to define an accommodating cavity together with the supporting member, the accommodating cavity is configured to accommodate the first assembly therein; and after the triggering subassembly is triggered, the unfolding subassembly is unfolded to open the accommodating cavity, and meanwhile the ejection subassembly ejects the first assembly out of the accommodating cavity.

A toy vehicle having a longitudinal central axis aligned in a direction of travel and for travel through a passageway of an elongated tubular track having a non-linear pathway which extends in three dimensions and which at least partly confines said toy vehicle, said toy vehicle comprising a first plurality of translational elements comprising two+2n, wherein n=1 or more, translational elements spaced about the longitudinal central axis of the toy vehicle for engagement with the inner surface of the elongated tubular track; and a second plurality of translational elements comprising two+2m, wherein m=1 or more, translational elements spaced about the longitudinal central axis of the toy vehicle for engagement with the curved inner surface of the elongated tubular track, wherein each of the translational elements of the first plurality of translational elements and each of the translational elements of the second plurality of translation elements are independently moveable in relation to each other and are biased in at least an outward radial direction from the longitudinal central axis of the toy vehicle, and a control system for controlling at least the operable rotational speed of at least two translational elements, wherein said at least two translational elements are drive translational elements.

A magnet holder insert comprising a magnet and magnet holder housing designed with internal wall features capable of keeping the magnet properly positioned in the holder device, and external wall features capable of keeping the magnet holder device securely mounted in the finished part. The internal and external fastening elements of the magnet holder housing are designed in such a way as to promote rapid and secure assembly of both the magnet device and the finished part. The exposed surface of the magnet holder device can be configured with flat or dome shaped exposed contact surfaces, depending on how secure or flexible the magnetic joining feature is intended, capable of attaching to another magnet device or a material susceptible to magnetic attraction.

A magnetic smart modular toy includes a main body and plural external components magnetically assembled to the main body. Users can control the action of the toy by a smart mobile device to carry out a near-distance or long-distance batter or contest game with other persons. During the game, if any one of the external components on the main body of the toy falls out due to collisions, the toy will be able to change an action mode, and upload the information to a cloud platform by the smart mobile device, so that a third party's smart mobile device can display the status of the toy, so as to produce the effect of a long-distance interactive game or contest.

The present disclosure provides a collision judgment method and apparatus. The method includes: determining, by a moving device, according to acceleration data collected by an acceleration sensor, that the moving device collides; sending collision information to the corresponding control device, including at least a moving device identifier and a collision time; sending, by the corresponding control device, the collision information to a collision judgment device; detecting, by the collision judgement device, whether at least two collision information sent by the at least two control devices is received within a predetermined time interval; when the at least two collision information is received within the predetermined time interval, and a difference between collision times carried in the at least two collision information is less than a preset threshold, determining that moving devices corresponding to moving device identifiers carried in the at least two collision information collided with one other.
