摘要： A mobility vehicle may comprise a frame, a first pivot arm, a second pivot arm, and a suspension assembly. The first pivot arm may be coupled to the frame and coupled to a drive wheel. The second pivot arm may be coupled to the frame and coupled to a ground engaging caster wheel. The suspension assembly may be coupled to the frame. The suspension assembly may include a first spring assembly and a second spring assembly. The first spring assembly may be disposed about a first spring axis and coupled to the first pivot arm. The second spring assembly may be disposed about a second spring axis and coupled to the second pivot arm. The first spring axis and the second spring axis may be disposed relative to each other at an angle of no greater than about 150° when the mobility vehicle is operating on horizontal ground.

摘要： The present disclosure includes methods of operating a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, one or more pairs of arm assemblies, and one or more sensors. The arm assembly includes a wheel configured to move from a first spatial location when the wheelchair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly, and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair. The methods adjust the maximum operational speed of the wheelchair when the seat is in an elevated position based on sensor data relating to one or more of the arm limiter position and the position of the frame.

摘要： In some embodiments, a vehicle may include a frame having longitudinal axis. The vehicle may include a steering assembly having a steering input and at least one wheel. The steering assembly may be coupled to the frame and configured to steer the vehicle based on input from a steering input. The vehicle may include a first drive wheel and a second drive wheel. The vehicle may include a steering position sensor configured to detect steering input including a position of the steering input and at least one of i) a rate of change of position of steering input and ii) steering position time. The vehicle may include at least one controller configured to process a signal from the steering position sensor and, in response to the processed signal, drive the first drive wheel and the second drive wheel, the first drive wheel being driven independent of the second drive wheel.

摘要： The present invention relates to a scissors lift comprising a bottom frame, a top frame and a scissors mechanism arranged between the bottom frame and the top frame to displace the bottom frame and the top frame relative to each other by transfer of an actuation force. The scissors mechanism comprises a central hollow scissors arm delimited between opposite scissors arm surfaces, wherein the central hollow scissors arm has a bottom pivotal connection connecting it to the bottom frame and a top pivotal connection connecting it to the top frame. Further, the mechanism comprises two passive scissors arms being pivotally connected to the bottom frame and pivotally connected to the top frame. Each of the two passive scissors arms are pivotally connected to the central hollow scissors arm on the opposite scissors arm surfaces of the central hollow scissors arm. Further, the scissors lift comprises a motor providing said actuation force, said motor located between said opposite scissors arm surfaces of said central hollow scissors arm. Thereby, the motor may be protected and at least partially enclosed by the scissors lift and even by the central hollow scissors arm, allowing a safer and/or more easily maintained scissors lift.
