Disclosed is a stroller with detachable auxiliary power structure, which includes a stroller body, a power control module, and a battery unit. The stroller body includes a front wheel member, a rear wheel member, a left folding member, and a right folding member. Front ends and rear ends of the right and left folding frames are pivotally connected to the front wheel member and the rear wheel member, respectively. The power control module is mounted to a bottom of the rear wheel member and includes a drive motor that outputs a rotational speed and a torque, a gear box, and a power output shaft that has one end connected to the gear box and an opposite end connected to the rear right wheel or the rear left wheel. The battery unit is connected to the drive motor to serve as a power source.

The invention relates to a three-wheeled transport carriage, in particular for a golf bag, comprising a first elongated frame part and a second elongated frame part which can be pivoted relative to the first frame part and on the front end of which a front wheel is pivotally attached via a wheel holding bracket. The two rear wheels are hinged to a cross-member in the hinge region between the first and second frame parts in a pivotal manner about approximately 90.

A walking-type electric carrier, comprising a handlebar, a driving mechanism, and a carrier frame that is connected to the driving mechanism; the handle bar comprises an armrest cross-bar, a vertical post that is vertically connected to the armrest cross-bar; the vertical post is connected to the driving mechanism; the vertical post is provided with a lifting handle, and the armrest cross-bar is provided with a detachable handle component; the handle component comprises a handle base and a handle body; the handle base and the handle body are detachably connected; the driving mechanism is controlled by the handle body to propel the carrier to move.

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.

A gyroscopically-responsive power assisted moment arm is disclosed for use in connection with vehicles such as load carrying devices. A moment arm extends to a pivot point such that when a longitudinal force is applied at the moment arm, a sensor senses such force and outputs an energizing signal to a motor to drive a wheel. If a rotational or vertical force is applied to the moment arm, the motor need not be driven. According to the invention, therefore, a power assist can be provided to a user to drive a wheel in a desired direction of transport while not causing drive during tipping or unloading of the load carrying portion of the vehicle. Such an apparatus can be advantageously applied to a power assisted wheelbarrow, as one exemplary application.

In the specification and drawings an accessory cart is described and shown with a base, a housing element that is connected to the base and extends upward from the base, and a platform, which is connected to the housing element with the height of the platform being automatically adjustable.

A patient support apparatus includes a base having a length and including a plurality of caster wheels enabling movement of the patient support apparatus across a floor surface. An auxiliary wheel support structure is secured to the base and rotatably supports at least one non-castered auxiliary wheel about a rotational axis transverse to the length of the base for engagement with the floor surface. The auxiliary wheel support structure may be configured to support the auxiliary wheel and to enable movement of the auxiliary wheel out of engagement with the floor surface to a non-engaged position wherein the at least one auxiliary wheel is out of engagement with the floor surface. A control apparatus is in communication with and moves the at least one auxiliary wheel between at least one deployed position and a non-engaged position.

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.

A motorized wheelbarrow assembly for includes a wheelbarrow that has a pair of handles and a wheel rotatably coupled between the pair of handles. The wheel may roll along a support surface. A drive unit is coupled to the wheelbarrow. The drive unit is in mechanical communication with the wheel. The drive unit selectively rotates the wheel to urge the wheelbarrow along the support surface.

The present invention provides an electric pullet truck in the technical field of land transportation equipment. The electric pullet truck comprises a frame including two forks; a steering drive assembly including i) a drive wheel component disposed behind the frame; ii) an oil cylinder component to drive the forks up, which includes a cylinder body and a plunger which could telescopically move within the cylinder body, wherein the cylinder body is fixedly connected with the drive wheel component; iii) a supporting seat component including an annular sleeve and two support arms extending from both sides of the annular sleeve, wherein the annular sleeve is covered outside of a lower portion of the oil cylinder body; and iv) a handle seat component fixedly connected with an upper portion of the cylinder body. The electric pullet truck of the invention has advantages like a high degree of integration and smooth steering.
