A multi-pedal-controlled caster and a method for using the caster are provided. The multi-pedal-controlled caster includes a main body support, a connecting rod, an orientation mechanism, a braking mechanism, a reset mechanism, a first inner tooth member, a second inner tooth member, a pair of wheel members and three elastic members, where the main body support is relatively rotatable and is combined with the connecting rod, and the first inner tooth member and the second inner tooth member are fixedly mounted on the connecting rod. A multifunctional pedal is treaded to push a first warping plate to make the first warping plate clamped into a first recess portion of the first inner tooth member, so that the caster can run in an orientated manner; and the multifunctional pedal is treaded again to push an auxiliary braking member.

The present disclosure in at least one embodiment provides a corner module for a vehicle, including a front-wheel corner module configured to drive a front wheel and including a front-wheel inwheel motor installed on the front wheel to generate a driving force and a friction braking device configured to generate a braking force on the front wheel, a rear-wheel corner module configured to drive a rear wheel and including a rear-wheel inwheel motor installed on the rear wheel to generate a driving force, a driving information detector configured to detect driving information of the vehicle, and an electronic control unit configured to control the front-wheel corner module to form a friction braking force by using the driving information and to control the rear-wheel corner module to form a regenerative braking force, wherein the front-wheel corner module uses the front-wheel inwheel motor that is provided with a lower specification than the rear-wheel inwheel motor to save the manufacturing cost, and the rear-wheel corner module has no friction braking device installed so that the rear-wheel inwheel motor is undamaged by heat.

A support arrangement having an activation mechanism to control the movement of wheels is provided. The support arrangement includes a platform, a chassis attached to the platform, a pair of wheel assemblies movably coupled to the chassis, and the activation mechanism. The pair of wheel assemblies are operable between a first state and a second state. The activation mechanism includes a track having a first stable position and a second stable position spaced along a length of the track, and a pin configured to travel along the track. Wheels are in the first state when the pin is in the first stable position and are in the second state when the pin is in the second stable position.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

The present disclosure provides a gantry for an X-ray system. The gantry may include a base section, a lifting section, and a swing section. The base section may be configured to move. A first end of the lifting section may be connected to the base section. A first end of the swing section may be rotatably connected to a second end of the lifting section. A radiation assembly may be disposed on a second end of the swing section.

A wheel assembly for an infant support apparatus includes a wheel mount, a wheel pivotally connected with the wheel mount about a pivot axis, and a brake member assembled with the wheel for movement between a braking state and a release state, the brake member when in the release state being rotatable with the wheel relative to the wheel mount, and the brake member when in the braking state engaging with the wheel mount to block rotation of the wheel relative to the wheel mount.

An article movement system includes an article and at least one ball wheel. The article has first and second article surfaces meeting at a first article edge. The ball wheel is located along the first article edge and includes a ball, a bearing arrangement and a shell. The ball engages a surface underlying the article, the bearing arrangement supports the ball for omni-directional rotational movement, and the shell is located along the first article edge and contains the ball and the bearing arrangement. The shell defines a non-circular ball opening through which a portion of the ball extends to contact the underlying surface. The article, the bearing arrangement and the shell are configured such that the ball wheel is able to support the article for omni-directional rolling motion over the underlying surface with either of the first and article surfaces parallel thereto, and at any orientation therebetween.

A portable detachable pulley is provided, which includes a gasket, and a buckle assembly is provided on the lower end face of the gasket. The buckle assembly includes two symmetrically distributed first buckles fixedly mounted on the lower end face of the gasket, and a second buckle is provided between the two first buckles. The second buckle is located at an end portion of one side of the two first buckles, and a fastening component is provided at the other end portion of the two first buckles. A connecting piece is movably mounted between the first buckle and the second buckle, and a pulley assembly for rolling is provided beneath the connecting piece. The pulley is designed for use both with and without the pulley assembly, depending on circumstances, such that the processes of assembly and disassembly are highly user-friendly and do not necessitate the use of any tools.

A desk assembly with a frame, a seat, and a desk. The frame is configured to support the desk assembly on a horizontal surface and has guide rails extending between a first end and a second end of the frame. The seat is securely attached to the first end of the frame and has an adjustable position. The desk has a desk platform and legs that are movably coupled to the guide rails. The desk is vertically adjustable between a standing position where the desk platform is positioned at a first height and a sitting position where the desk platform is positioned at a second height lower than the first height. While in use, the frame is configured to remain stationary with respect to the horizontal surface and the desk is moveable along the guide rails between the first end and the second end of the frame.

Disclosed is a corner module apparatus for a vehicle. The corner module apparatus includes processors configured to receive a braking initiation manipulation input of a vehicle from a driver. The corner module apparatus also includes a controller configured to perform braking of the vehicle by independently controlling steering of four wheels of the vehicle based on a direction angle when the braking initiation manipulation input is received by the one or more processors in a state in which the vehicle is positioned on the slope. The direction angle is an angle between an inclined direction of a slope and a longitudinal direction of the vehicle.
