A stroller frame, comprising at least one motor, particularly an electric motor, for assisted driving of the stroller frame, a pusher bar for pushing the stroller frame and at least one force sensor device for detecting a direction and/or an amount of force and/or a force component acting on the pusher bar, and/or for detecting a value derived from said force or force component, particularly a temporal change of the force or force component.

The present invention provides a simulated inflatable wheel including a rim, a filler tire mounted on the rim, and a tire casing covering the filler tire and having a rolling portion in rolling contact with the external environment and an abutting portion extending from two sides of the rolling portion. The abutting portion is located between the rim and the filler tire. The abutting portion abuts against the rim and the filler tire respectively. A recessed portion is formed on at least one position of an outer surface of the filler tire. The present invention utilizes the recessed portion of the filler tire to generate space between the filler tire and the rim (or the tire casing), for providing a buffer when the filler tire is deformed and improving elasticity of the filler tire. The present invention further provides a stroller including the simulated inflatable wheel.

A wheel shock absorption structure and a child carrier having the wheel shock absorption structure, including a wheel shaft and a wheel seat connected with a frame, and a lower end of the wheel seat is rotatably connected with a wheel through the wheel shaft. Further including a shock absorber with an elastic structure, an upper end of the shock absorber is removably connected with an upper end of the wheel seat, and the shock absorber rotates synchronously along with the wheel seat; a lower end of the shock absorber is rotatably connected with the wheel shaft which is slidably connected with the lower end of the wheel seat. The shock absorber is driven by sliding of the wheel shaft to generate recoverable elastic deformation to provide damping and buffering. The bending deformation of the shock absorber ensures that the wheel shock absorption structure has a better shock absorbing effect.

A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support frame to influence motion of the patient transport apparatus over a floor surface. The auxiliary wheel is movable to a deployed position with the auxiliary wheel engaging the floor surface and a stowed position with the auxiliary wheel spaced a distance from the floor surface. An actuator assembly including a lift actuator a biasing device, and a biasing load adjustment assembly. The lift actuator is operable to move the auxiliary wheel to the deployed position and to the stowed position. The biasing device configured to bias the auxiliary wheel towards the deployed position. The biasing load adjustment assembly configured to adjust a biasing force being applied by the biasing device to the auxiliary wheel.

A two-wheeled vehicle is provided. The two-wheeled vehicle includes a chassis, and a first wheel carriage moveably coupled to, and longitudinally displaceable relative to the chassis. At least a first wheel is rotationally mounted on the first wheel carriage, and coupled to the chassis through the first wheel carriage. The two-wheeled vehicle further includes a first linear actuator system coupled to the first wheel carriage, and configured to longitudinally displace the first wheel carriage relative to the chassis. A first motor is mounted to the first wheel and the first wheel carriage. The first motor is configured to provide a drive energy to the first wheel, and to be displaced along with the first wheel carriage as the first wheel is displaced by the first linear actuator system.

The present disclosure relates to a wheel connecting structure and a baby carrier. The wheel connecting structure includes a fixed base, a rotatable base, a rotating shaft and an anti-swing member. The rotatable base is rotatably connected to the fixed base by the rotating shaft. The anti-swing member has an abutting portion. The anti-swing member is arranged on one of the fixed base and the rotatable base, and the abutting portion abuts against the other of the fixed base and the rotatable base. The abutting portion is provided with a lubricating structure.

The present disclosure relates to a motorized wheel system comprising a shaft comprising a proximal end and a distal end connected by an elongated middle portion, the proximal end of the shaft connected to a collar fastener, wherein the distal end of the shaft is attached to a connector; the collar fastener configured to attach to a transportable device; a connector connecting the distal end of the shaft to an outer retention enclosure; the outer retention enclosure comprising the outer surface, an inner surface, and a substantially hollow interior at least partially disposed around a motor unit and a wheel structure; the wheel structure comprising a wheel and a stabilizing unit connecting the wheel structure to the outer retention enclosure; and the motor unit configured to provide rotational movement to the wheel structure.

A transport vehicle for transporting at least four passengers through an airport has a body. A front passenger seat is disposed in the body and is dimensioned to seat two adults thereon. A rear passenger seat disposed in the body and is dimensioned to seat two adults thereon. An operator area, for supporting an operator of the vehicle is disposed on the body. The rear passenger seat is disposed between the front passenger seat and the operator area. A distance from a front of the body to a rear of the operator area is less than a depth of an airport elevator, and a width of the body is less than a width of an airport elevator door.

An eccentric wheel adjustment device includes a hub (1), an adjustment disk (2) and a release structure (3). The hub (1) has an axle portion (10) eccentrically arranged and an inner ring portion (11) formed around the axle portion (10). The adjustment disk (2) has a disk seat (20) for the hub (1) being pivotally disposed thereon and a positioning member (21) for positioning the hub (1) on the disk seat (20).
