Adjustment mechanism of head-mounted display device, head-mounted display device, and display method thereof

A head-mounted display device, comprising:

• a housing;
• first and second display assemblies mounted in the housing via corresponding first and second adjustment mechanisms, each adjustment mechanism comprising:
• an adjustment rod;
• and
• a transmission assembly, wherein:
• the adjustment rod is positionable in a first state and a second state wherein, the adjustment rod in the first state is dis connected from the transmission assembly and triggers, upon receipt of physical manipulation, an electrical component in the head-mounted display device to send a signal;
• and
• the adjustment rod in the second state is connected to the transmission assembly and transmits power to the transmission assembly upon receipt of a rotation operation;
• and
• the transmission assembly receives power transmitted by the adjustment rod and drives a display assembly of the head-mounted display device to perform nearsightedness or farsightedness adjustment, wherein:
• the first and second display assemblies are arranged in a first direction;
• and
• each of the corresponding first and second adjustment mechanisms is disposed on a side of the corresponding display assembly that faces away from the other display assembly;
• an adjustment rod of the adjustment mechanism is slidably received in the housing;
• the adjustment rod includes a first end that extends outside the housing;
• the adjustment rod is positioned in the first state when the first end of the adjustment rod is displaced in close proximity to the housing;
• and
• the adjustment rod is positioned in the second state when the first end of the adjustment rod is displaced away from the housing.

A head-mounted display device, comprising:

• a housing;
• first and second display assemblies mounted in the housing via corresponding first and second adjustment mechanisms, each adjustment mechanism comprising:
• an adjustment rod;
• a limiting assembly;
• and
• a transmission assembly, wherein:
• the adjustment rod is positionable in a first state and a second state wherein, the adjustment rod in the first state is dis connected from the transmission assembly and triggers, upon receipt of physical manipulation, an electrical component in the head-mounted display device to send a signal;
• and
• the adjustment rod in the second state is connected to the transmission assembly and transmits power to the transmission assembly upon receipt of a rotation operation;
• and
• the transmission assembly receives power transmitted by the adjustment rod and drives a display assembly of the head-mounted display device to perform nearsightedness or farsightedness adjustment, wherein:
• the first and second display assemblies are arranged in a first direction;
• and
• each of the corresponding first and second adjustment mechanisms is disposed on a side of the corresponding display assembly that faces away from the other display assembly;
• an adjustment rod of the adjustment mechanism is slidably received in the housing;
• the adjustment rod includes a first end that extends outside the housing;
• the adjustment rod is positioned in the first state when the first end of the adjustment rod is displaced in close proximity to the housing;
• the adjustment rod is positioned in the second state when the first end of the adjustment rod is displaced away from the housing;
• and
• the limiting assembly comprises a spring plate and a rotating member, wherein the spring plate is fastened to a mechanical part in the housing, the spring plate including a first accommodating groove and a second accommodating groove that are spaced from each other, wherein:
• the rotating member comprises a rotating portion, a first rotating arm and a second rotating arm that are each connected to the rotating portion;
• the rotating portion is rotatably disposed on the mechanical part in the housing
• the first rotating arm is provided with a first limiting pole;
• the first limiting pole is displaced between the first accommodating groove and the second accommodating groove as the rotating member rotates;
• and
• the second rotating arm is provided with a second limiting pole;
• and
• a peripheral side of the adjustment rod is provided with a clamping groove that is configured to clamp the second limiting pole, the adjustment rod is configured to drive, via the second limiting pole, the rotating member to rotate when the adjustment rod slides such that the adjustment rod is positioned in the first state when the first limiting pole is received in the first accommodating groove and the adjustment rod is positioned in the second state when the first limiting pole is received in the second accommodating groove.
