  • Publication number: 20250052359
    Abstract: A base structure of a cooling fan and a manufacturing method of the base structure are provided. The base structure includes a bearing, a shaft sleeve and a base. The bearing defines therein a first cylindrical cavity for receiving a shaft of the cooling fan. The shaft sleeve is made of a first material and defines therein a second cylindrical cavity. The shaft sleeve includes a protrusion part and a first engagement structure arranged at a first end and a second end of the shaft sleeve, respectively. The base is made of a second material and includes a second engagement structure. The second engagement structure is interlocked with the first engagement structure since the second engagement structure is integrally formed with the base. The first material has a greater rigidity than the second material.

  • Patent number: 11005250
    Abstract: A structure for supporting a wire includes a first portion including a body portion, and an alignment portion. The alignment portion defines a first alignment opening through which the alignment portion receives a first fastener. The first alignment opening extends along a first alignment axis between. A second portion defines a second alignment opening, extending along a second alignment axis, through which the second portion receives the first fastener. The second portion is spaced a distance from the body portion to define a wire opening into which the wire is received for support by the structure. The alignment portion is movable relative to the body portion between a first position, in which the first alignment axis and the second alignment axis are coaxial, and a second position, in which the first alignment axis and the second alignment axis are non-coaxial.
