Abstract: An application program recommending method may include acquiring current context information of the terminal, acquiring an amount of context information generated when the terminal runs a first application program, where the first application program refers to an application program stored in the terminal, determining a to-be-used recommending mechanism according to the amount of the context information generated when the terminal runs the first application program, and determining, according to the to-be-used recommending mechanism, a second application program corresponding to the current context information, where the second application program refers to a to-be-recommended application program; and displaying the second application program. In this way, accuracy of predicting an application program to be used by a user is improved. Moreover, when historical information of using an application program by the user is insufficient, a to-be-recommended application program can also be accurately determined.

Abstract: The present invention discloses a tapered braking device for electric winches which disposes a section of gear shaft, a section of core shaft, a wedge shape support, braking plates, an elastic element, a wedge shape piece A, a wedge shape piece B, a braking clutch base and so on in a gear box of an electric winch. When a motor works, the section of core shaft of the motor can drive the braking clutch base and the wedge shape pieces A, B to rotate, until a gap is formed between the friction faces of the wedge shape support and the wedge shape piece B and the braking plates so that the braking action stops. When the motor suddenly stops, a heavy load lifted by a tight wire rope reel provides a reverse pulling force so that the wedge shape piece B produces a reverse thrust force to push the friction faces of the braking plates, so the braking effect is achieved quickly.
