A stroller can include a body having a pair of driving wheels mounted to left and right sides thereof; a motor configured to rotate the pair of driving wheels; a frame comprising a lower part connected to the body, the frame extending upwards from the lower part; a handle connected to the frame; a sensor unit including a force detection sensor configured to detect force applied to the handle, a touch sensor configured to detect whether the handle is being grasped, and a wheel sensor configured to detect rotation of the pair of driving wheels; and a controller configured to calibrate the force detection sensor based on data detected by the touch sensor and the wheel sensor.

A rotational sliding bearing having a static part and a mobile part, each having a sub-shell with a sliding surface, each surface arranged within an angular range of max. 180° relative to the rotational axis in the direction of rotation of the bearing, and in a closed rest position, the sub-shells of all parts together form a bearing bush, the mobile part is arranged to pivot about a pivot axis for opening the bearing relative to the static part, such that a shaft mounted in the bearing is released in a release position, and the mobile part is shaped such that, based on the sliding surface position relative to the rotational axis, in the closed rest position, a translation of a shaft accommodated in the bearing is prevented transversely to the rotational axis and in the direction of the pivot axis of the mobile part or in the counter direction.

A wheelbarrow with an electric motor built into the wheel helps the user to push and brake the wheelbarrow. A sensor is installed on the handle support, which detects the position of the hand in the axial direction. A button is mounted on the handle support next to the handle. There is an acceleration sensor and a gyroscope on the wheelbarrow. Based on the axial movement of the hand, the wheelbarrow controller calculates the pushing or pulling force of the arms on the handles. The operation of the electric motor is controlled by the wheelbarrow controller via the motor controller, based on the information received from the motor controller, the detected sensor values and the switch status. As a result, the force of the electric motor can be used effectively for an additional drive or braking, so that the required push force of the arms can be reduced. When braking, the motor acts as a generator and charges the battery. Two batteries are placed in the supported legs of the wheelbarrow, which contributes to the weight balance of the wheelbarrow and allows good cooling of the batteries. The construction of the frame provides battery protection and is adapted to transportation on a towing hitch of a passenger car.

A multi-functional stroller comprising an incline detection system, and a braking system. The multi-functional stroller can detect when rolling uncontrolled, or when a user is not grasping the multi-functional stroller and engage the braking system to keep stroller occupant in safety. In embodiments, the multi-functional stroller can have motorized wheel hubs to aid in navigating stairs or uneven terrain.

According to an example of the present disclosure, there is provided an electric board that can switch between automatic and manual operation including a frame configured to accommodate an occupant; a plurality of wheels moving the electric board; a plurality of motors respectively installed on the wheels; and a lever coupled directly to the motor and configured to manually cut off electric power applied to the motor through an operation of a user. When the electric power applied to an electronic brake provided in the motor is cut off by the lever, an operation of the electronic brake which controls a gearwheel of the motor by the electric power is stopped, and the electric board is configured to be converted into a state of being controlled by manual power of the user.

The invention relates to a pram comfort device (10, 12) for a pram, in particular a pram axle and/or a pram wheel (12), with an axle and/or a wheel (200), wherein the axle is designed as what is referred to as an intelligent axle and/or the wheel (200) is designed as what is referred to as an intelligent wheel (200), and an additional comfort function can be provided for the pram by means of the axle and/or by means of the wheel (200). Furthermore, the invention relates to a pram underframe or a pram, wherein the pram underframe or the pram has a pram comfort device (10, 12) according to the invention.

A pallet sled includes a base and a pair of tines extending from the base. A load wheel supports outer ends of each of the tines. A wheel supports the base. At least one motor is configured to drive the base wheel or at least one of the load wheels for driving the pallet sled. The motor may be a hub motor inside the base wheel or the load wheel.

A kit for motorizing a golf bag cart, a motorized golf bag cart, and a method of motorizing a golf bag cart are disclosed herein. The kit can include brackets having clamps, a golf cart drive unit, and a remote control. Each bracket is used to replace a rear wheel assembly of a non-motorized golf bag cart. The clamps are used to attach the golf drive unit to the cart. The remote control is used to control and steer the cart via the attached golf cart drive unit. The golf cart drive unit includes two motors, two axles, two wheels and an axle aligning member. The axles slide relative to the axle aligning member to accommodate golf bag carts having different rear wheel spacing.

A vehicle system includes a chassis, a plurality of wheels coupled to the chassis and supporting the chassis for rolling on a surface, and a riding platform coupled to the chassis. The riding platform is for supporting a user behind the chassis when the riding platform is in a downward pivoted state. A linkage connects the riding platform to the chassis for selective pivotal motion relative to the chassis between an upward pivoted state in which the riding platform is pivoted into a position to allow a user to walk behind the chassis and a downward pivoted state in which the user may ride or step on the platform.

A transporting apparatus comprising: a standing platform adapted for a user to stand on and wherein the platform has at least two wheels connected to it; a carrying means; a base with at least two drive wheels associated with it and wherein the base is connected to the standing platform; a drive motor which is in communication with the at least two drive wheels and with an accelerating means; and an accelerating means which is in communication with the drive motor; the apparatus is adapted such that when in use a user is able to load items into the carrying means and then stand on the platform and then engage the accelerating means which results in the apparatus moving forward.
