  • Patent number: 12191719
    Abstract: The present disclosure provides a motor including a stator, a rotor and a first circuit board. The stator includes a winding assembly including a plurality of coils. A conductive element is extended out from the winding assembly and is electrically connected to a first electrical connector. The first electrical connector penetrates through a pillow of the stator and is electrically connected to the first circuit board. The motor further includes a second circuit board electrically connected to the first circuit board, and a first insulation plate, a second insulation plate and a third insulation plate for fixing and protecting the circuit boards. The motor also includes a clip for fixing and heat dissipating an electronic component disposed on the second circuit board.

  • Publication number: 20230412034
    Abstract: The present disclosure provides an external rotor motor including a rotor, an air guider, a pillow and a stator. The rotor includes a hub. The air guider includes a connecting ring and rotor air-guiding members. The connecting ring is disposed on the hub. The rotor air-guiding members are disposed on the connecting ring. A first gap is formed among any two adjacent rotor air-guiding members and the connecting ring. The pillow includes a stator flange, a cylinder and fins. The stator flange is disposed on the cylinder. The fins are radially arranged on a first surface of the stator flange. A second gap is formed among any two adjacent fins and the stator flange. A first acute angle is formed between a radial extension direction of each of the fins and a first tangent direction of the cylinder. The stator is mounted on the pillow and rotates along an axis.

  • Publication number: 20210330524
    Abstract: A transport apparatus has a mobile chassis, a lifting mechanism, two armpit supports structured and operated mirror-symmetrical to one another, and two seat assemblies. The lifting mechanism includes a lifting arm for assembling a chest rest and two lifting racks, and a linear actuator driving the lifting arm to pivot upward or downward. The armpit supports are assembled on the lifting racks and transversely extend toward a rear of the mobile chassis. The seat assemblies are assembled on the mobile chassis. Each of the seat assembly has a seat plate driven to rotate by a drive motor to form a seat. The weak person can be moved directly by the transport apparatus with voice command or with a remote control. Since the weak person is not moved by the care workers, the weak person can be moved in an easier and safer way.

  • Publication number: 20200229999
    Abstract: A transport apparatus for weak person has a mobile chassis for transporting the weak person, a powered lifting mechanism and a seating assembly assembled on the mobile chassis. The lifting mechanism has a lifting arm connected to be driven to pivot upward or downward by an actuator, and an armpit supporting device assembled on an upper end of the lifting arm. The seating assembly has a seat supporting mechanism, and two seat plates mounted on the left and right seating arms of the seat supporting mechanism and are connected to and driven by two driving assemblies respectively to form a seat for the weak person to sit thereon.
