Claim 7:
8. An automatic vehicle jack assembly for automatically lifting a vehicle for performing service on the vehicle, said assembly comprising:
a plurality of scissor jacks, each of said scissor jacks being mounted to a bottom side of the vehicle, each of said scissor jacks being positioned adjacent to a respective one of a plurality of wheels on the vehicle for lifting the respective wheel upwardly from a support surface when each of said scissor jacks aligned with the respective wheel is actuated into an extended position, each of said scissor jacks being actuatable into a retracted position thereby facilitating the respective wheel to roll along the support surface, each of said scissor jacks comprising:
a housing having a top wall, a bottom wall and an outer wall extending between said top wall and said bottom wall, said outer wall having a front side, a back side, a first lateral side and a second lateral side, said housing being elongated between said front side and said back side, each of said first lateral side and said second lateral side of said outer wall being substantially open into an interior of said housing, said top wall having a pair of first tabs each extending outwardly beyond a respective one of said front side and said back side of said outer wall, said top wall having a pair of second tabs each extending outwardly beyond a respective one of said first lateral side and said second lateral side of said outer wall, each of said second tabs being centrally positioned between said front side and said back side, each of said first tabs having mounting holes extending through said first tabs, each of said second tabs having mounting holes extending through said second tabs, said top wall abutting the bottom side of the vehicle having fasteners extending through said mounting holes in each of said first tabs and each of said second tabs for fastening said housing to the bottom side of the vehicle;
a screw being rotatably positioned within said housing, said screw having a first end rotatably engaging said front side of said outer wall, said screw having a second end rotatably engaging said back side;
a motor being coupled to said front side of said outer wall of said housing, said motor engaging said first end of said screw, said motor being actuatable to rotate said screw in a first direction or a second direction;
a pair of sleeves, each of said sleeves having said screw extending therethrough such that each of said sleeves threadably engages said screw, each of said sleeves travelling toward a respective one of said first end and said second end of said screw when said motor rotates in said first direction, each of said sleeves travelling away from said respective first end and second end of said screw when said motor rotates in said second direction;
a pair of scissors, each of said scissors having an upper end and a lower end, each of said scissors pivotally engaging each other, said upper end of each of said scissors pivotally engaging a respective one of said sleeves, each of said scissors being collapsed when said motor rotates said screw in said first direction such that said lower end of said scissors is positioned adjacent to said bottom wall of said housing, each of said scissors being extended when said motor rotates said screw in said second direction such that said lower end of said scissors is spaced downwardly from said bottom wall of said housing, said lower end of each of said scissors having a plurality of lobes each extending away from said lower end, said lobes on a respective one of said scissors being spaced apart from each other and being distributed around a substantial circumference of said lower end of said respective scissor, said lobes on said lower end of each of said scissors being positioned between respective lobes on said lower end of a respective one of said scissors when said scissors are extended and retracted to retain said scissors at a degree of extension or retraction when said motor is turned off; and
a foot having a pair of panels each extending upwardly from a top surface of said foot, said panels being spaced apart from each other, said lower end of each of said scissors being positioned between each of said panels, said lower end of each of said scissors pivotally engaging a respective one of said panels, a bottom surface of said foot abutting the support surface when said scissors are extended wherein said foot is configured to facilitate said scissors to lift the vehicle upwardly from the support surface; and
a control panel being positioned within a cab of the vehicle wherein said control panel is configured to be accessible to a driver of the vehicle, said control panel being in communication with each of said scissor jacks thereby facilitating said control panel to independently or simultaneously actuate each of said scissor jacks between said extended position or said retracted position, said control panel including a plurality of control buttons being movably integrated therein, each of said control buttons being electrically coupled to said motor of a respective one of said scissor jacks for actuating said motor in said respective scissor jack to rotate said screw in said respective scissor jack in either said first direction or said second direction for lifting or lowering the vehicle, said control panel being electrically coupled to a power source comprising an electrical system of the vehicle.
