Abstract: A fan frame of an axial-flow fan is provided to reduce the vibration generated during the rotation of the impeller that is transmitted to the outside of the axial-flow fan via the fan frame. The fan frame includes a housing, a base and a plurality of connection members. The base includes a shaft-coupling portion. Each of the plurality of connection members includes two ends respectively connected to the housing and the base. Each of the plurality of connection members is defined with an extension line passing through the two ends of the connection member. Each of the plurality of connection members includes a first bending portion and a second bending portion. The first bending portion extends around a first notch, and the second bending portion extends around a second notch. The extension line extends through the first and second notches.

Abstract: An antenna structure includes a housing, a first connecting portion, a matching unit, a second connecting portion, and a first switching circuit. The housing defines a slot, a first gap, and a second gap. The housing is divided into a first portion and a second portion by the slot, the first gap, and the second gap. The second portion is grounded. One end of the first connecting portion electrically connected to the first portion and another end of the first connecting portion electrically connected to a feed point through the matching unit. The first portion is divided into a first radiating portion and a second radiating portion by the first connecting portion. One end of the second connecting portion is electrically connected to the first radiating portion and another end of the second connecting portion is grounded through the first switching circuit.

Abstract: A motor is provided to improve the damp proof or dustproof effect of the conventional motor. The motor includes an isolating housing, a sealing member and an inner assembly. The isolating housing includes first and second housing parts. A through-hole is formed between the first and second housing parts. The through-hole communicates an internal space of the isolating housing with an external space. The sealing member includes a frame portion and a wire receiving portion. The wire receiving portion is integrally formed with the frame portion. The frame portion is arranged between the first and second housing parts. The wire receiving portion is disposed at the through-hole. A lead wire is received in the wire receiving portion, and includes one end extending into the internal space of the isolating housing. The inner assembly is received in the internal space of the isolating housing and electrically connected to the lead wire.

Abstract: An antenna structure includes an antenna holder, a feed unit, a grounding unit, a first radiating unit, a second radiating unit, a third radiating unit, a parasitic unit, and a coupling unit. The feed unit and the grounding unit are positioned on the antenna holder and are spaced apart from each other. The first radiating unit and the third radiating unit are both electrically connected to the feed unit. The parasitic unit is electrically connected to the grounding unit. The first radiating unit couples with the second radiating unit and the parasitic unit. The second radiating unit further couples with the coupling unit and is grounded through the coupling unit.

Abstract: A motor and a sealing member thereof are provided in the present invention. The motor includes a housing, a stator and a rotor. The stator is received in the housing. The rotor includes a shaft and a permanent magnet. The shaft is rotatably coupled to the housing, and one end of the shaft extends out of the housing through a shaft hole. A gap is formed between the shaft and the shaft hole. The permanent magnet is coupled with the shaft and spaced from the stator. A sealing member is arranged on the housing and surrounds the shaft hole. The sealing member includes a blocking portion abutting with a predetermined part of the rotor outside the housing. The blocking portion seals the gap. As such, dustproof and damp-proof functions of the motor are improved.

Abstract: The present disclosure provides an impeller and a mold for manufacting the impeller. The impeller includes a plurality of blades, and there is an overlapped area between two adjacent blades. The mold includes a first part, a second part and a plurality of slide groups. The first part and the second part move in a mold opening direction. At least a portion of each slide group is located in the overlapped area, and each slide group has a first slide block and a second slide block, and a movement direction of the first slide block and the second slide block is perpendicular to the mold opening direction. By using that the movement direction of the slide group is perpendicular to the mold opening direction, the impeller with blades that have the overlapped area may be manufactured. The blades of the impeller may have a special shape.
