1. A head-mounted device support assembly, comprising:
a housing assembly, configured to accommodate a length-adjustable arm and a tightness adjustment mechanism; wherein the length-adjustable arm has an original length; a first switch is arranged on the housing assembly; wherein the tightness adjustment mechanism is connected to the length-adjustable arm and configured to adjust a length of the length-adjustable arm;
a force-receiving member, detachably arranged on the housing assembly; and
a control module, electrically connected to the tightness adjustment mechanism and configured to control, based on an adjustment signal from the tightness adjustment mechanism, the tightness adjustment mechanism to drive the length-adjustable arm to move, allowing the length to be increased or reduced to a target length from the original length;
wherein the force-receiving member comprises an elastic pad, and an ejecting member disposed within the elastic pad; the ejecting member is disposed in correspondence to the first switch and extends along a thickness direction of the elastic pad;
wherein the first switch comprises a first metal piece and a first elastic member, the elastic pad has a mounting recess defined therein, and an opening of the mounting recess faces the first elastic member;
wherein the ejecting member comprises a support piece attached to a bottom of the mounting recess, and an ejector pin disposed on a surface of the support piece and extending in a direction towards the opening of the mounting recess;
when the force-receiving member is in a moving state under an external force, the ejector pin is capable of contacting and pushing the first elastic member, allowing the first elastic member to be separated from the first metal piece, wherein an electrical connection path between the control module and the tightness adjustment mechanism is disconnected, and the length of the length-adjustable arm is the target length;
when the force-receiving member is in an initial state, there is a gap between the ejector pin and the first elastic member, and the electrical connection path is connected.
