Abstract: A brake control device includes a housing, a brake lever, a hydraulic seat and a piston. The housing is formed of a plastic and includes a handlebar mounting portion at an end thereof that is mounted to a bicycle handlebar. The brake lever is pivotably connected to the housing at a pivot of the housing. The hydraulic seat is disposed within the housing and is distal from the handlebar mounting portion. The hydraulic seat is formed of a metal and defines a piston chamber and a hydraulic reservoir therein that are in fluid communication with each other. The piston is movably mounted to the piston chamber in the hydraulic seat, and is operably connected to the brake lever. The plastic of the housing is adhered to the hydraulic seat.

Abstract: An electronic device includes a linkage mechanism, a platform and a display module. The linkage mechanism includes a connecting structure, a bottom base and a top plate. The connecting structure includes a connecting plate, two pivoting members and a stopping member. The two pivoting members are respectively located at two opposite ends of the connecting plate. Each of the pivoting members includes a limiting piece. The stopping member is movably disposed on the connecting plate, and has two fastening portions respectively fastened to the limiting pieces. One of the pivoting members is pivotally disposed on the bottom base. The other pivoting member is pivotally disposed on the top plate. When the stopping member is moved and detached from the limiting pieces, the connecting structure is adapted to pivot relative to the bottom base and the top plate respectively.
