Abstract
An electronic jack for lifting heavy objects, such as a portion of a vehicle is described. The electronic jack has an outer casing that houses a motor, a hydraulic system, and a hydraulic lift unit that is activated by the hydraulic system. The motor is preferred to be a twelve volt electric motor and can be electronically connected to a vehicle through a cigarette lighter adapter.
Claims1
An electronic jack comprising:
- a rectangularly shaped base comprising a front end and a rear end;
- the base further having four wheels comprising a left front wheel, a right front wheel, a left rear wheel, and a right rear wheel;
- an internal electric motor located within the base;
- a power cord having two ends, a first end and a second end, with the first end of the power cord being attached to the motor, the second end of the power cord having a cigarette lighter adapter, wherein the adaptor allows the jack to draw power from a vehicle electronics by connecting the adapter into an adapter slot within the vehicle;
- a control switch attached to the power cord in between the adapter and the first end of the power cord;
- a reduction gear unit;
- wherein the motor is connected to a plurality of reduction gears that are located within the gear reduction unit;
- the reduction gear unit is further coupled to an offset shaft;
- the offset shaft is coupled to a first arm, the first arm is coupled to a second arm
- a hydraulic pressure container is located within the base, the pressure container further comprises
- a piston, the piston being coupled to the second arm;
- a two compartment hydraulic fluid container is located within the base, the fluid container having a first and second compartments;
- wherein the first and second compartments define two compartments of equal volume and, further, the compartments are positioned side by side within the hydraulic fluid container;
- an electronic pressure relief solenoid valve located in between the compartments the valve further electronically connected to the motor;
- a pressure hose having two ends, a first end and a second end wherein the first end of the pressure hose is connected to the hydraulic pressure container via a one-way valve, while the second end of the pressure hose is connected to the first compartment of the fluid container;
- a short feeder tube having two ends, a first end and a second end, with the first end of the feeder tube connected to the second compartment of the fluid container and the second end of the feeder tube connected to the hydraulic pressure container;
- a hydraulic lift unit is located within the base;
- wherein the hydraulic lift unit is contiguous with the first compartment of the fluid container.
