Battery Powered Vehicle Jack

A vehicle jack, comprising:

• a base coupled to a battery;
• a carriage movably coupled to translate along the base, the carriage include a drive nut;
• a saddle configured to engage a vehicle;
• a lift arm including a first end pivotally coupled to the saddle to define a first axis and a second end pivotally coupled to the carriage to define a second axis;
• a crank arm with a third end that is pivotally coupled to the base to define a third axis and a fourth end that is pivotally coupled to the lift arm to define a fourth axis that is between the first axis and the second axis;
• a lead screw threadably engaged with the drive nut;
• and
• an electric motor configured to receive power from the battery and operable rotate the lead screw to adjust an angle between the lift arm and the crank arm to move the vehicle jack between a raised position corresponding to a minimum value of the angle and a lowered position corresponding to a maximum value of the angle.

A vehicle jack, comprising:

• a base coupled to a battery, the base including a first sidewall defining a first slot, a second sidewall defining a second slot, and a bracket between the first sidewall and the second sidewall;
• a carriage movably coupled to translate along the base, the carriage include a drive nut, a first pad that is received in the first slot, and a second pad that is received in the second slot;
• a saddle configured to engage a vehicle;
• a lift arm positioned between the first sidewall and the second sidewall, the lift arm including a first end pivotally coupled to the saddle to define a first axis and a second end defining a yoke that is pivotally coupled to the carriage to define a second axis;
• a crank arm with a third end that is pivotally coupled to the bracket and a fourth end that is pivotally coupled to the lift arm to define a fourth axis that is between the first axis and the second axis,
• a lead screw threadably engaged with the drive nut the lead screw having a first end that is rotatably coupled to the bracket;
• and
• an electric motor configured to receive power from the battery and coupled to a second end of the lead screw to rotate the lead screw to adjust to cause a vertical movement at a first end of the lift arm between a lowered position corresponding to a maximum angle between the lift arm and the crank arm and a raised position corresponding to a minimum angle between the lift arm and the crank arm.
