  • Patent number: 10980147
    Abstract: A quick release cooling fan structure without wires includes a housing, a quick release member, a carrying member, and a conductive member. A motor is fixed and electrically connected to the carrying member, and the carrying member is quickly assembled to the quick release member in a rotate-in manner. An abutting block of the quick release member is engaged with the locking portion of the housing. The connecting piece of the quick release member cooperates with the groove of the housing for quick assembly, the conductive member is disposed in the first through hole, and the conductive end is inserted through the first and second through holes to come into electric contact with the conductive portion, and thus the internal electric connection inside the cooling fan can be achieved without the use of wires, and the assembly and disassembly of the cooling fan can also be achieved.
