Head mounted display device
A head mounted display device includes a host, two sliding parts, two locking parts and two brackets. The host has two connecting bases located on opposite sides of the host. The two sliding parts are respectively slidably connected to the corresponding connecting base. The two locking parts are respectively used to lock the corresponding sliding part in a retracted position or a pulled-out position relative to the corresponding connecting base. The two brackets are respectively pivotally connected to one end of the corresponding sliding part away from the host.
1 . A head mounted display device, comprising:
a host, has two connecting bases located on opposite sides of the host;
two sliding parts, respectively slidably connected to the corresponding connecting base;
two locking parts, respectively used to lock the corresponding sliding part in a retracted position or a pulled-out position relative to the corresponding connecting base; and
two brackets, respectively pivotally connected to one end of the corresponding sliding part away from the host,
wherein each of the connecting bases has a hole, each of the locking parts has a first segment and a second segment connected to each other, a rod diameter of the first segment of each of the locking parts is larger than a rod diameter of the second segment, each of the sliding parts has a slot, each of the slots has a connecting section and a first end and a second end located at both ends of the connecting section, a hole diameter of each of the first ends and a hole diameter of each of the second ends are greater than or equal to the rod diameter of each of the first segments, a width of each of the connecting sections is less than the rod diameter of each of the first segments and greater than or equal to the rod diameter of each of the second segments, a hole diameter of each of the holes is smaller than the rod diameter of each of the first segments and greater than or equal to the rod diameter of each of the second segments, each of the second segments passes through the corresponding hole,
when each of the locking parts locks the corresponding sliding part in the retracted position, the first segment is located at the first end, and
when each of the locking parts locks the corresponding sliding part in the pulled-out position, the first segment is located at the second end.
2 . The head mounted display device according to claim 1 , wherein each of the locking parts further has a pressing part, located at one end of the second segment away from the first segment, and the pressing part and the first segment are respectively located at both sides of the corresponding hole.
3 . The head mounted display device according to claim 2 , further comprises two elastic parts, respectively set on the corresponding second segment and located between the corresponding connecting base and the corresponding pressing part, wherein an elastic restoring force of the elastic parts causes the pressing parts to have a tendency to move away from the holes.
4 . The head mounted display device according to claim 1 , further comprises two elastic parts, respectively arranged at pivot joints of the corresponding bracket and the corresponding sliding part.
5 . The head mounted display device according to claim 1 , wherein sliding directions of the sliding parts are parallel to each other.
6 . The head mounted display device according to claim 1 , wherein the sliding parts and the connecting bases are rectangular tubes.
