Abstract

The invention discloses an interpupillary distance adjusting device and wearable equipment, the interpupillary distance adjusting device comprises a driving motor and an adjusting assembly, the driving motor is provided with a driving shaft extending along a first direction, two opposite ends of the driving shaft are two driving ends, the adjusting assembly comprises two screw joint parts and two mounting parts, and the two screw joint parts are connected with the driving shaft through screws. The two screw joint parts are spaced in the first direction, the screw directions of threads are opposite, the two screw joint parts are located on the two sides of the driving motor in the first direction respectively so as to be connected with the two driving ends respectively, the two installation parts are used for installing two lenses respectively, the two installation parts are installed on the two screw joint parts respectively in a threaded mode, and the two installation parts are used for installing the two lenses respectively. When the two screw joint parts rotate, the two lenses are driven to get close to each other or get away from each other in the first direction, so that the driving motor and the screw joint parts are directly driven, the torque is directly conducted, and the positioning precision is high.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a pupil distance adjusting device and wearable devices. Background technique [0002] At present, the interpupillary distance adjustment of VR / AR headband displays or glasses lenses usually adopts a worm gear plus a two-way integral screw drive structure, and there are also double-motor accelerators and reducers that drive the left and right two-way screw drive structures respectively. Whether it is a worm gear structure or a dual-motor acceleration and decelerator structure, the adjustment device will take up a large space, there will be cumulative errors, and the torque transmission accuracy will be low. Contents of the invention [0003] The main purpose of the present invention is to propose an interpupillary distance adjustment device, aiming to solve the problems of large space occupation, accumulated error and low torque transmission accuracy of the current adju...
