  • Patent number: 9656384
    Abstract: A toolbox includes a body having multiple recesses defined in each of two facing insides thereof, and a groove is defined in each of the two facing insides of the body and located above the recesses. At least one bit receiving unit is pivotably connected to the body by pivotably engaging two pivots on two ends of the bit receiving unit with the recesses of the two facing insides. Two protrusions extend from each of the two ends of the at least one bit receiving unit and are located above the pivot corresponding thereto. When the bit receiving unit is pivoted upward, the protrusions are engaged with the grooves of the two facing insides of the toolbox so that the bit receiving unit is well positioned. When the bit receiving unit is positioned horizontally, the protrusions are engaged with the recesses of the two facing insides of the toolbox.

  • Patent number: 8974340
    Abstract: A hybrid mechanism is provided, including: an engine, a first motor, a second motor, a clutch, a hybrid unit, a differential, and a battery. The clutch, the second motor and the engine are sequentially coupled to one end of the hybrid unit, and the first motor and the battery are coupled to the other end of the hybrid mechanism. The battery provides supplying currents to the first motor or the second motor or receives range-extend currents from the second motor. The hybrid unit includes a first sun gear, a second sun gear, at least one planetary gear coupled to the first and second sun gears, and a planet carrier coupled to the at least one planetary gear. The hybrid mechanism has four modes. The hybrid unit harmonizes the first driving force from the first motor and the engine and the second driving force from the second motor and outputs a harmonized driving force to the differential.
