Abstract

A headband adjustment structure includes a rotary adjusting assembly, a wearing unit having an adjustable accommodation space, a cable management module located between the wearing unit and the rotary adjusting assembly for carrying a cable, an adjustment gear set linkably coupled to the cable management module, and a driving rotation shaft set passing through the wearing unit and the cable management module, and linkably coupled to the wearing unit and the adjustment gear set, and coaxially connected to the rotary adjusting assembly. When the rotary adjusting assembly rotates the driving rotation shaft set, the driving rotation shaft set synchronously moves the wearing unit to adjust the adjustable accommodation space, and moves the cable management module through the adjustment gear set. The amount of the movement of the cable management module is different from that of the wearing unit.

Claims9

Dependent claims

A headband adjustment structure, comprising:

a rotary adjusting assembly;
a wearing unit comprising a strip body having two end portions which are opposite to and overlapped with each other, wherein the strip body surrounds to define an adjustable accommodation space inside the strip body, and the two end portions respectively comprise a first toothed rack and a second toothed rack;
a cable management module located between the wearing unit and the rotary adjusting assembly for carrying at least one cable;
an adjustment gear set linkably coupled to the cable management module;
and
a driving rotation shaft set passing through the wearing unit and the cable management module, and linkably coupled to the wearing unit and the adjustment gear set, and coaxially connected to the rotary adjusting assembly, and the driving rotation shaft set comprising a first gear member, a second gear member, and a rotary shaft body coaxially coupled to the first gear member and the second gear member, and the first gear member being engaged with the first toothed rack and the second toothed rack,
wherein, when the rotary adjusting assembly rotates the driving rotation shaft set, the first pear member moves the two end portions of the strip body to travel in opposite directions so as to adjust a size of the adjustable accommodation space and moves the cable management module through the adjustment gear set in which an amount of movement of the cable management module is different from an amount of movement of the wearing unit.
