An electric skateboard has a frame assembly that includes a deck with an opening of the deck to house a battery case mounted to a bottom of the deck. The frame includes a top plate that covers the opening and forms with the battery case an enclosure. A battery pack is positioned in at least partially in the enclosure. Front and a rear trucks are mounted to the bottom of the deck. At least one of the first and front and rear trunks is coupled to first and second wheels mounted on axles of the front and rear trucks. The front truck is mounted on the front end and a rear truck is mounted on rear end of the deck. First and second wheels are powered by one motor with a differential and a shaft coupled to the first and second wheel. The motor is coupled to the shaft to rotate the first and second wheels. The motor is electrically connected to the battery pack through a rear channel. The motor rotates the first and second wheels in the same directions and propels the electric skateboard forward and backward.

Disclosed is a self-balancing vehicle including a left housing assembly, a right housing assembly, a left wheel train, a right wheel train and a rotation mechanism. The left wheel train is connected with the left housing assembly. The first end of the rotation mechanism is connected with the right wheel train and the right housing assembly, and the second end of the rotation mechanism is inserted into the left housing assembly and rotationally connected with the left housing assembly. The rotation mechanism is just arranged in the right housing assembly, but connected with the right housing assembly and the right wheel train respectively, thus reducing the strength requirements of the self-balancing vehicle on the left housing assembly and simplifying the components of the left housing assembly.

A self-balancing vehicle includes a vehicle body having a housing with left and right sides which are independently moveable. A unitary support bar is disposed within the housing, and a left drive wheel and an opposed right drive wheel are each coupled to the support bar. A bracket encircles the support bar; the bracket has a cylindrical body formed with a slot through the body. A set screw is fixed to the support bar and is received within the slot to limit rotational movement of the support bar with respect to the bracket.

A moving wheel platform that minimizes wheel interactions with noncontinuous and uneven surfaces. The platform provides rotation-inhibiting structures onto or into the moving wheel platforms that aids with eliminating wheel bite.

Skateboard training devices are provided to assist all levels and ages of skateboard enthusiasts in learning tricks. The devices can comprise a deck including a core comprising a set of materials, wherein the core is partially or entirely surrounded by an outer protective material. In some aspects, the core can be made of one or more of a wood, a plastic, a metal, a composite, a fiberglass, and nylon. In some aspects, the outer protective material comprises a foam material. In some aspects, the core can comprise a foam material that is denser than an outer protective foam material.

The utility model relates to the field of skateboard fitting, specifically relating to an adapter for surfskate comprising a fixing plate, a rotating plate, an centre shaft screw and a locking nut wherein said fixing plate and rotating plate link together via centre shaft screw and locking nut; a torsion spring is sleeved on centre shaft screw between fixing plate and rotating plate, and the top of torsion spring is fixed on fixing plate, and the bottom is fixed on rotating plate; said centre shaft screw located on top and bottom of rotating plate are sleeved with a thrust bearing wherein thrust bearing on the top of rotating plate is provided within torsion spring; on the side of fixing plate closing to rotating plate is equipped with limiting groove and on the side of rotating plate closing to fixing plate is equipped with limiting block matching with limiting groove.

Systems and methods for intelligent data center power management and energy market disaster recovery comprised of data collection layer, infrastructure elements, application elements, power elements, virtual machine elements, analytics/automation/actions layer, analytics or predictive analytics engine, automation software, actions software, energy markets analysis layer and software and intelligent energy market analysis elements or software. Plurality of data centers employ systems and methods comprising a plurality of Tier 2 data centers that may be running applications, virtual machines and physical computer systems to enable data center and application disaster recovery from utility energy market outages. Systems and methods may be employed to enable application load balancing and data center power load balancing across a plurality of data centers by moving application and power loads from one data center location using power during peak energy hours to another data center location using power during off-peak hours.

A sliding balance board has an eccentrically mounted center wheel as a pivotable central balancing member, a wheel with one-way sprag clutch bearings mounted near the left end of the board and a wheel with one-way sprag clutch bearings mounted near the right end of the board. A user balances himself/herself on the board, and yet slides the board to the left and right, back and forth by shifting his/her weight left and right, synchronized to the rocking motion of the eccentrically mounted center wheel.

A skateboard truck includes a metal bolt called a kingpin and a threaded fastener, called a hex nut, which when combined hold the two main components of a truck together: the baseplate, which is mounted to the bottom surface of the skateboard deck; and the turning part of the truck called the hanger, which is mounted onto the baseplate by means of the kingpin, and affixed tightly into the baseplate by means of a threaded hex nut. Two bushings placed along the shaft of the kingpin and on either side of a flange protruding from the hanger hold the hanger in place by the tightening of the kingpin into the threaded shaft nut fastener. The kingpin is oriented such that a threaded portion of the kingpin (on an end opposite a bolt head portion) is generally facing towards a bottom surface of the skateboard deck.
