A portable winch assembly includes a winch mechanism connected to a support structure adapted to be manually transportable. Coupling fixing sections are also provided at the two seat width direction sides of the backboard section, the coupling fixing sections engaging with the front side of the side frames and supported by the side frames. A locking element is rigidly attached proximal to a second lengthwise edge of the slot. The linking members are further connected to a lever such that they can be moved in opposite directions from left to right or from right to left so as to cause the bell cranks to rotate in opposite directions. The method includes: detecting a first operation performed by the user on the first display region in a first operation mode different from the voice operation mode; and in response to the first operation, triggering a first operation instruction and executing the operation function corresponding to the prompt information. The array substrate comprises a substrate, a gate line and a pixel electrode disposed on the substrate, a common electrode disposed above and overlaying the gate line, wherein a strip-shaped through hole is disposed on the common electrode and at least a portion of the strip-shaped through hole is positioned right above the gate line.
