Problems solved by technology

[0002] Current head-mounted display devices, such as but not limited to AR (Augmented Reality, augmented reality) glasses, VR (Virtual Reality, virtual reality) glasses, and MR (Mixed Reality, mixed reality) glasses, are applied to these head-mounted display devices The interpupillary distance adjustment mechanism usually adopts gear meshing transmission. When the head-mounted display device is subjected to impact, such as falling to the ground and suffering a violent impact, it may cause abnormal or even functional failure of the interpupillary distance adjustment mechanism, such as Tooth jumping, gear deformation and abnormal meshing, etc., and then make the interpupillary distance adjustment function of the head-mounted display device invalid

Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0039] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses an interpupillary distance adjusting mechanism and head-mounted display equipment, and the interpupillary distance adjusting mechanism comprises a cylinder body; a piston which is connected in the cylinder body in a sliding mode, wherein the piston comprises a driving piston and a driven piston which are arranged at an interval, and the driven piston is used for being connected with a lens cone of the head-mounted display equipment; and a driving part which is in driving connection with the driving piston; a transmission cavity is formed between the driving piston and the driven piston and filled with fluid. According to the technical scheme, the risk that the pupil distance adjusting function of the head-mounted display equipment is abnormal can be reduced, and the service life of the equipment is further prolonged.

Description

technical field [0001] The present invention relates to the technical field of head-mounted display devices, in particular to an interpupillary distance adjustment mechanism and a head-mounted display device. Background technique [0002] Current head-mounted display devices, such as but not limited to AR (Augmented Reality, augmented reality) glasses, VR (Virtual Reality, virtual reality) glasses, and MR (Mixed Reality, mixed reality) glasses, are applied to these head-mounted display devices The interpupillary distance adjustment mechanism usually adopts gear meshing transmission. When the head-mounted display device is subjected to impact, such as falling to the ground and suffering a violent impact, it may cause abnormal or even functional failure of the interpupillary distance adjustment mechanism, such as Tooth jumping, gear deformation and abnormal meshing, etc., and then make the interpupillary distance adjustment function of the head-mounted display device invalid. ...
