A wearable device configured to selectively provide roller transportation, the wearable device including a shoe, a plurality of wheel assemblies, each wheel assembly being configured to selectively roll relative to a ground surface about an associated axis of rotation, and a frame connected between the wheel assemblies, the frame comprising a trunk and a plurality of branches extending from the trunk, each of the branches being configured for connection to at least one of the plurality of wheel assemblies, wherein at least a portion of the shoe is located vertically higher than at least a portion of the frame when at least one of the wheel assemblies is in contact with the ground surface and the at least one of the wheel assemblies is positioned to selectively roll relative to the ground surface.

The present invention discloses a flat ground cross-country type roller skate comprising a skate body (1), wherein a wheel assembly at a lower part of the skate body, wherein the wheel assembly comprises a mounting seat (6) used to mount the skate body (1) and a hoisting mechanism disposed on the mounting seat (6). There are at least three wheel assemblies disposed on the hoisting mechanism, and each wheel assembly can hoist independently under the action of the hoisting mechanism. Thus, the wheel assemblies of the roller skate can be hoisted independently so as to adapt to various roads with uneven surface.

A drive module for a skateboard, the drive module comprising at least one axle with at least one wheel which is or can be driven by an electric motor, and a frame, which is connected to the axle and has a receiving space for an energy storage unit, in particular for a secondary battery, the drive module being replaceably connectible to the skateboard. Also, a set and a skateboard comprising the drive module.

A wearable device configured to selectively provide roller transportation, the wearable device including a shoe, a plurality of wheel assemblies, each wheel assembly being configured to selectively roll relative to a ground surface about an associated axis of rotation, and a frame connected between the wheel assemblies, the frame comprising a trunk and a plurality of branches extending from the trunk, each of the branches being configured for connection to at least one of the plurality of wheel assemblies, wherein at least a portion of the shoe is located vertically higher than at least a portion of the frame when at least one of the wheel assemblies is in contact with the ground surface and the at least one of the wheel assemblies is positioned to selectively roll relative to the ground surface.

A shock-absorbing bushing is provided for a skateboard and includes a first layer and a second layer. The first layer has first value of hardness. The first layer is provided with a through hole. The second layer has a second value of hardness. The second layer is coupled to an outside surface of the first layer. The first layer and the second layer are formed of plastic materials coupled together as a unitary body and exhibiting at least two different values of hardness, such as being flexible in the interior and stiff in the exterior, or being stiff in the exterior and flexible in the interior. The skateboard shock-absorbing bushing is mountable to the skateboard by for example being coupled to an axle of a retainer seat to which a roller support frame is mounted.

The present invention discloses a flat ground cross-country type roller skate comprising a skate body (1), wherein a wheel assembly at a lower part of the skate body, wherein the wheel assembly comprises a mourning seat (6) used to mount the skate body (1) and a hoisting mechanism disposed on the mounting seat (6). There are at least three wheel assemblies disposed on the hoisting mechanism, and each wheel assembly can hoist independently under the action of the hoisting mechanism. Thus, the wheel assemblies of the roller skate can be hoisted independently so as to adapt to various roads with uneven surface.

A wheel assembly having a plurality of wheel trucks spaced apart on a base plate for supporting a vehicle that uses the wheels of the wheel truck to move along a supporting surface. Each wheel truck provides two wheels sharing an independent axle in which each independent axle includes a quick release pin configured to both removably and rotatably connect the two wheels to the wheel truck.
